Crop storage technology - Receiving hopper | RH 20 / RH 24

Intake volume up to 25 m³, soil cleaning and pre-grading

The Receiving hopper RH 20 and RH 24 suit medium to larger farms. Special constructive features of the hopper are the large horizontal discharge at the top end, active pocket sealings and the particularly soft PU spiral rollers of the cleaning unit. These features enable maximum crop protection and highest throughput capacity. The infinitely variable drive (standard) allows easy adaptation to various requirements. The various options allow an optimum adaption to the customer needs.

Highest crop protection

The soft, wear-resistant polyurethane (PU) spiral rollers achieve lowest impact on the crop and an effective separating performance.In addition, jammed stones and entangled haulm are avoided.

Benefits

Thoroughly cleaned

The centrifugal cleaning system Turbo Clean offers the possibility to remove sticky soil from the rollers. Turbo Clean is ideal for sticky, adhesive soils. By use of an automatic timer it can be activated without the need for manual intervention.

Continuously proven settings

The "Adjustment Control" feature for GRIMME receiving hoppers enables the digital display of speeds and spacings of the PU spiral rollers. Especially for inexperienced operators, the system allows quick and precise adjustment of the machine to recurring harvesting conditions and tuber sizes to achieve consistent separation results and accurate pre-grading. For maximum accuracy of the graded tubers, be sure to check the fractionated crop with potato sizing squares.

Mechanically height-adjustable rubber intake flap

The height of the rubber intake flap can be adjusted easily and without tools, so that a simple, perfect adaptation to different transport vehicles is possible.

Gentle and crop protective

The deep, soft bunker bags ensure a gentle crop handling and even unloading.

Maintenance-free

The rollers are driven directly and without loss of power by one hydraulic motor each. The speed of each pair of rollers can be adjusted independently of each other. Furthermore, the groups of rollers are adjustable in distance to achieve the best results with different crop sizes.

Powerful and gentle

For maximum crop protection with the highest separation performance, GRIMME has perfected the soft PU spiral rollers over the years. The soft spiral rollers have a high self-cleaning effect to achieve an optimal cleaning result without obstructions even under difficult, sticky conditions.

Optimum crop flow

The infinitely adjustable hopper floor speed enables an optimum crop flow

Especially designed for receiving hoppers

The GRIMME operator terminal GBT 831 has been specially developed to operate the receiving hoppers and Combis. All functions can be adjusted and displayed in a convenient and clearly laid-out manner.

Capacity Control

A sensor which monitors the filling level of the receiving hopper regulates the optimum hopper floor speed at all times. In this way the entire storage line is used to its capacity without manual readjustment.

Capacity Control

Long service life

The sturdy bunker floor chain ensures a long service life and minimal maintenance.

Gentle crop transfer

The minimal drop step enables gentle crop transfer from the hopper floor to the PU spiral rollers.

Infinitely adjustment

The speed of the roller-sets can be infinitely adjusted for optimum and particularly gentle crop cleaning. The infinitely variable spacing and inclination adjustment of the PU spiral rollers enables quick adaptation of the soil cleaning to varying soil and trash proportions. The intensity of cleaning can be adapted via levelling adjustment.

Comfortable operation

The individually configurable operator terminal VC 50 allows each user to adapt his own user-interface in that way, that he is able to make settings as quickly and conveniently as possible.

The storage line evolves into an assembled unit

Flow Control connects all machines that belong to one storing line to each other. The entire line can be stopped by each machine without delay or automatically stops itself in case of trouble. The entire storage line can be started at the push of a button in a programmed start-up sequence from any terminal. In order to avoid blockages, the machines start from the final discharge point of the storage line back to the receiving hopper with a programmable time offset. The minimal manual control effort allows the entire line to be operated by a single person, thus reducing the need for additional manpower. In conjunction with the automatic speed control of the hopper floor, called Capacity Control, a uniform crop flow in the entire storing line can be ensured under all conditions.

Trouble-free operation

The Top Clean belt scrapers ensure that the belts run smoothly on heavy, sticky soils.

Thoroughly cleaned

pre-grading into up to three different size fractions (calibres)

The receiving hoppers of the RH 20 and RH 24 series are able to clean the crop and to pre-grade it in a single pass of the machine. With the aid of one or two pre-grading units, connected in series, it is possible to generate up to three pre-grades.

SoftFlow

Simple solution for a gentle and crop-protecting transfer from one conveyor to the next via soft, flexible and self-cleaning PU-fingers.
