Grimme DR 1500 potato digger – description and properties

Grimme potato rotor: DR 1500, SE 150-60, 75-30, BR 150, GT 170, potato digger, price

Combine Grimme produced by a German company. The technique is delivered to many countries around the world. The harvester also performs many functions. The machine digs potatoes, separates tubers from the tops, puts the vegetables in the hopper, and then unloads it into the van, which delivers the hopper to the right place.

The units are supported on the side. The comb is in the main part. The gravel unit consists of rollers for cutting the leaves and selecting the depth of the gravel, knives and cutting slicers. Potatoes with tops arrive on a belt that feeds the tubers to the sieve unit.

Here the tops are separated, the root vegetables are cleaned of chaff, and the tubers are sorted by size. Smaller vegetables go into a special compartment and then into a funnel with flexible soil. The potatoes are then unloaded onto transport.

The combines are characterized by high productivity. The machines have a ring-shaped elevator, in which the tips are collected, and the tubers are perfectly cleaned. The device contains a large selection of options, there is a possibility of levelling, the main difference from the models of other manufacturers is a smooth running. The disadvantage is the difficulty of repair, as it is difficult to find spare parts.

Machines can be single-row and double-row. The first are used to work in a small area. They can be used on stony surfaces. The hopper holds 2-4 tons of potatoes. The two-row have a hopper capacity of 5.5-7.5 tons, these machines process large areas. The conveyor belt can be lowered. This technique is able to work in poor environmental conditions.

How to make a potato digger with your own hands

Artisans have many options. The simplest one contains a shovel-shaped insertion group, the function of which is to lift a row of potatoes and release the tubers. Next comes the elevator, consisting of two chains, between which there are poles. Its frame also serves to accommodate the gear and engine.

Significant carburetor of a Chinese chainsaw

To make the frame of the elevator, 45×45 mm corners are used. On top, a group of plows lifts a pile of land with potatoes and chain wheels, through which the conveyor belt is driven. On the sides, slopes are made of steel board, which serve to cover the chains. In addition, 4 brackets are provided, 2 of which serve for the slats that adjust the angle to the machine, the other 2 – to attach the conveyor to the latter.

The elevator consists of a rod chain conveyor, which is used in branded combine harvesters. With their own hands shorten the chain, leaving 44 sticks, the latter is made shorter – 30 cm and installed on the chain wheels on the frame.

The engine is from a moped, D-6. Its power is enough to drive an elevator. The engine is assembled together with a reducer, which transmits the rotation to the draft shaft of the sponsor. The gearbox consists of 2 chain gears and chain wheels. The first fit from a moped, the second fit from a bicycle with minor modifications.

Popular models

Nowadays, various models of the combine are produced. Let’s consider the changes in more detail.

Design and operating functions

The Grimme DR 1500 is characterized by a modular design, with which you can quickly change individual units and use the device in different environments. The optional equipment expands the potential of the model. The running gear is designed according to the standard scheme (in the form of a wheeled body). A pneumatic braking system is used here.

When torque is twisted on the units come chains and waves. An optional hydraulic tilt setting mechanism is available. It ensures that the side conveyors remain horizontal on slopes, which prevents the bulb flow from shifting in the direction of the slope.

The tractor trailer is reorganized in terms of sides, height and length. Hydraulic drawbar adjustment is available on request. The pivot shaft is in the middle, which means that the wheels can turn to the right and left.

The harvesting process for the Grimme DR 1500 is a sequence of operations involving the main elements. The gravel section collects the plant matter. The excavator is represented by 2 drums, shovel delta and slicers, which are reorganized laterally and in height. Depending on the situation, the excavator closes automatically so that the potatoes do not fall backwards.

After the roder, the vegetable mass arrives on the first sieve belt in a flower ribbon construction. The working area of this sponsor is 5.5 square meters. The mass then enters the second conveyor belt with a sieve area of 1.75 square meters. The elements ensure gentle use of the crop. The first conveyor has a vibration-driven sponsor, and the second conveyor has a vibration-rotating sponsor. The devices are continuously adjustable. The model uses conveyors with a passage width of 40, 35, 30, 26, 24, 20, 18 and 15 mm. The third sieve with a passage width of 20 mm is the last one. For areas overgrown with weeds, a mechanical vibrator is used, which optimally distributes the river along the sponsor and improves the separation of impurities from the plant mass. The sieve belts are fitted with large ribs, patented by Grimme, to prevent the tubers from coming into contact with the sharp parts.

The tips of the root crops are separated at the first and second sponsons’ outlets. There are small grippers on the conveyor belt to ensure that long grass residues are released from the flow. Elevator for small grass is used for cleaning. The element is equipped with razor-sharp rubberized strips, making it versatile for any type of soil. Good sorting is also performed in poor conditions (the presence of stones, clumps of earth and small grass).

According to the elements of the sieve, the crop falls into a circular elevator with a 2-row tolerance. Due to its high capacity, the elevator eliminates the possibility of bottlenecks where the tubers get damaged. A special supporting belt, which works in synchronization with the elevator and facilitates the continuous operation of the harvesting grid, ensures that the tubers are always in perfect harmony with each other. In front of the belt, there are 2 half-waves that distribute the vegetables on the feeding belt.

The sorting process also takes place on a sorting table with an overturning roller and 2 conveyor belts.

The final product goes into a hopper with a floor belt that can hold up to 4.5 tons and has a variable output. One of the features of the Grimme Mähdescher DR 1500 is the top location of the hopper, which gives more space for manipulation during the emptying process. The filling cone in the middle of the design is set in different hopper positions, which allows you to work with tall machines as well. The scraper floor has a high unloading speed and ensures complete emptying in 20 seconds. The system is driven by a hydraulic motor. The hopper is driven to the unloading position by 2 hydraulic cylinders, 2 other hydraulic cylinders drive the harvester to the transport position and fold the head of the hopper.

Design and operation of Grimme potato harvesters

Grimme potato harvesters cover a wide range of self-propelled and excluded mechanisms for fast recovery of the root crop. The main working tool of the Grimm potato harvesters is the grave digger, which is buried several decimeters into the ground, which exceeds the mixed tubers with the soil mass. The crest consists of such structural elements:

  • Rollers that contribute to the removal of the mass separated by foliage;
  • 2 knives;
  • Knife for slicing feathers.

The angle of the knives and the depth of the whole ridge are individual.

In order to rake off the root crops from the layer of soil and contamination of the tops, the next stage of work on the shevator is carried out. In addition to being peeled, the potatoes can also be calibrated for size. Most of the vegetable mix goes into a special attractor with a movable floor, from which it is then reloaded into a truck and transported to storage locations.

Vegetable peelers

By using combinations to peel potatoes, manual labor can be minimized. Grimmma machines, which are represented by a German high-tech company, are very popular in today’s market. The production of agricultural machinery is located in the city of Damma.

The factory started its work in 1936. Then Franz Grimme first stopped the machine, with which it was possible to peel potatoes. Over time, the company managed to establish a conveyor production of specialized devices for harvesting beets, potatoes and other vegetables. Grimme products are exported to 120 countries. A wide dealer network is constantly inclined to expand.

Features

The potato harvesters presented by Griobe are in great demand among farmers. Thanks to their use, many functions can be performed at the same time. Such machines offer potato cleaning and launching of tubers from the tips. At the same time, the separation of various impurities takes place.

During cleaning, the potatoes are stored in a special hopper, and then unloaded into another vehicle and delivered to the specified location. Grimme combines have a side trench type. The ridge is on the outside of the main machine.

Potato harvesters are equipped with a special harvesting device. One of these devices consists of rollers to remove the haulm and adjust the depth of immersion, two knives and spring-loaded cutting discs. It should be noted that the angle of the knives can also be adjusted.

During operation this device removes a layer of soil of a certain thickness. The potatoes together with the tops fall on a special belt, which conveys the dug up crop to the sifting mechanism. Here, the tops are cut off, the potatoes are freed from soil and leaves, and the crop is sorted according to size. The smaller tubers go into a special compartment. After this, the potatoes go into a special hopper with a movable floor, from where the crop is unloaded to another vehicle.

advantages and disadvantages

Grimme combines are distinguished by the high quality of processing and the corresponding level of productivity. These machines are equipped with a ring elevator, in which the modified shoots are collected. The large volume of this element and the constantly working support belt prevent accidental accumulation of the crop. In addition, the advantages of this model include:

  • optimal cleaning of the tubers;
  • good visibility from the cab;
  • Large optional kit and the ability to customize it;
  • Slope compensation function;
  • The smoothest possible running of the machine.
