Handling equipment - Receiving hopper | RH 12 Combi

Intake volume up to 8 m³, soil cleaning, picking and pre-grading.

The compact receiving hopper, type RH 12 Combi, especially suits medium sized farms. The hopper floor, which is made of soft rubber, the roller package consisting of PU spiral rollers and the infinitely drive enable maximum crop protection and optimum throughput. Several handling steps in the storage and preparation process can be combined in just one machine: Crop intake, soil cleaning, picking, power pre-grading and pre-grading. The machine can be assembled from a wide range of options to meet the customer's specific requirements. On the optional available roller picking table, the crop is conveyed in rotation, which provides an excellent picking possibility. Furthermore, the platform on both sides offers sufficient space and a perfect, safe stand to the picking staff. Depending on the requirements as regards accuracy of grading and gentle crop handling, the RH 12 Combi can be combined with a web grader or a one- resp. two-step coil unit, made of polyurethane.

Benefits

Height adjustable 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.

Roller picking table

The ergonomically designed roller picking table allows the crop to be inspected from all sides, as the crop rotates around its own axis. The comfortable platform offers space for up to 4 persons. 

Developed for the picking staff

The clearly laid out operator terminal GBT 818 has been specifically developed for the picking personnel on the RH Combi. The display shows all the essential parameters that are important for the picking process.

Crop protective, flxible hopper floor made of rubber

The hopper floor made of rubber, with its specially arranged 15 mm high flights ensures as well a safe and gentle transport of the crop as a reliable emptying of residues.

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.

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.

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.

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.

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.

Trouble-free operation

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

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.

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.

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.

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.

SoftFlow

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

Variable use

The receiving hopper RH 12 Combi can be used variably thanks to a wide range of different sorting or pre-grading units. The optional use of a web grader WG 900 or additional PU spiral rollers for pre-grading behind the picking table enables the crop stream to be fractionated into two or three fractions of different size.

Even and gentle crop transfer

The rollers for soil cleaning and those of the roller picking table are mechanically coupled. In this way a constant and protective crop flow is always ensured, even if the spacing of the rollers of the cleaning unit is modified.

• Compactly designed receiving hopper, particularly suitable for narrow building arrangements
• Gentle intake due to soft rubber floor
• The special shape of the rubber-flights on the belt leads to optimum dragging effect and supports a high protection of the harvested crop.
• Optimum crop flow due to infinitely variable hopper floor speed
• Gentle crop discharge from the hopper floor onto the spiral coils.
• Gentle soil cleaning with PU spiral rollers
• Infinitely speed adjustment in two packets (coil 1, 3, 5 and 2, 4, 6) ensure an optimal and crop protective soil separation
• Quick adaption of the soil cleaning to varying amount of trash via infinitely distance adjustment of the PU-coils
• Perfect transfer in variable conditions: A constant and protective crop flow from the soil cleaning unit onto the roller picking table is even ensured, when the distance of the rollers of the cleaning unit are adjusted. This is made possible by a mechanical coupling of the cleaning unit and the roller picking table.
• Ergonomically designed picking platform.
• The receiving hopper RH 12 Combi can be used variably thanks to a wide range of different sorting or pre-grading units. The optional use of a web grader WG 900 or additional PU spiral rollers for pre-grading behind the picking table enables the crop stream to be fractionated into two or three fractions of different size.
• Maintenance free direct drives
• Comfortable operation via operator terminal type GBT 831
