Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large number of drivable rotary brushes in a state in which the axis of rotation of the brushes is in a lateral direction and in which the rotary brushes form a receiving and accommodating portion for rinsing crop water. The present invention relates to a crop cleaning apparatus configured to wash crops such as carrots and radishes placed in parallel in a receiving / holding unit with a rotating brush.

[0002]

2. Description of the Related Art Conventionally, the above-mentioned crop cleaning apparatus has been constructed so that the crops washed with water are artificially taken out from the receiving storage.

[0003]

However, the work of taking out the washed crops is troublesome, and there is room for further improvement in terms of workability improvement. An object of the present invention is to make it possible to easily and quickly take out the washed crop from the receiving storage unit without damage to the crop.

[0004]

The feature of the present invention is to provide a large number of drivable rotating brushes in a state in which the axis of rotation is in a horizontal direction, and the rotating brushes form a receiving container for washing the crops. In the crop cleaning device installed side by side in the formed state, the crop discharge tool is provided in the receiving storage part so as to be reciprocally movable in the direction of the rotation axis of the rotary brush, and the crop discharge port can be opened and closed at one end of the movement of the crop discharge tool. And a drive unit for moving the crop discharge tool to the discharge port side while the rotary brush is driven and rotated.

[0005]

Action: In other words, after the crop is washed with water, the discharge port is opened, and when the rotating brush is driven, the drive unit moves the crop discharge tool to the discharge port side. Rotation of the brush reduces friction between the brush and the crop. The crop can be smoothly moved to the discharge port side, and the washed crop can be taken out from the receiving and accommodating portion easily and promptly and without damage to the crop.

[0006]

As a result, it has become possible to provide a crop cleaning device which is much more excellent in workability and which can easily and rapidly take out a washed crop from a receiving and accommodating portion without damage to the crop.

[0007]

[Example] As shown in FIG. 1, a crop cleaning device 1 for rinsing long and narrow crops such as carrots and radishes is provided, and a belt conveyor 3 and a conveyor are provided to carry the crops out of a hopper 2 for storing the rinsed crops. Provided with a belt conveyor 4 with protrusions, provided with a crop alignment transport device 5 for aligning the crops from the belt conveyor 4 in a posture in which the longitudinal direction is lateral to the transport direction and sending the crops one by one, and the crop alignment transport device 5 A crop sorting device 7 is provided for sending the crops supplied one by one from the collection units 6 according to weight ranks.
A chute 8 and a belt conveyor 9 are provided to return crops falling from the hopper 2, and a chute 10 and a container 11 for collecting crops not sorted by the weighing and sorting apparatus 7 are provided to automatically sort the crops by weight. It constitutes a crop selection device.

In order to form the crop cleaning device 1, as shown in FIGS. 2 and 3, a large number of drivable rotating brushes 12 are provided.
In a state where the axis of rotation is in a horizontal direction, and in a state in which the receiving accommodating portion 13 for rinsing the crop water is formed by the rotating brushes 12, the rotating brushes are juxtaposed inside the water receiver 15 with the drainage channel 14,
A water supply pipe 16 for showering the washing water on the crops in the receiving and accommodating portion 13 is provided, and the crops are washed by the action of the brush 12 which is driven and rotated. Receiving housing 13
A crop discharge tool 17 is provided therein by a pair of rotary screw shafts 18 so as to be reciprocally movable in the direction of the rotation axis of the rotary brush 12, and a crop discharge port 19 is provided at a moving end of the crop discharge tool 17 so as to be opened and closed by a shutter 20. , Outlet after washing crops with water 19
Open, move the crop discharge tool 17 to the discharge port 19 side,
It is configured such that the washed crop can be easily and quickly taken out from the receiving storage 13 into the hopper 2. As shown in FIG. 4, all of the rotating brushes 12 are linked by a chain 21 to a first motor 22, and both rotating screw shafts are linked by a chain 23 to a second motor 24 which can be switched between forward and reverse rotation. In a state in which 12 is driven and rotated, the crop discharge tool 17 is moved to the discharge port 19 side by the second motor 24,
The rotation of the brush 12 reduces the friction between the brush 12 and the crop so that the crop can be smoothly moved to the discharge port 19 side. It is configured to be moved to a retracted position on the side opposite to the discharge port 19.

As shown in FIG. 5, an elastically stretchable sheet 25 is stretched in the hopper 2 and a cushion material 26 is placed on the sheet 25 to cushion the crop damage caused by the crop cleaning device 1 being fed with the crop. The bottom wall 2a of the hopper 2 is constructed so that it can be prevented by the cushioning action of the material 26 and the sheet 25.
While increasing the capacity of the hopper 2 by loosening the inclination of
The sheet 25 is configured to be surely dropped and supplied to the conveyor 3 by the sheet 25 being steeply inclined by the elastic restoring force as the amount of stored crops decreases. The left and right side walls 2b of the hopper 2 are connected to each other by a water supply pipe 27 on the conveyance end side of the conveyor 3 so that the hopper 2 can perform final cleaning as necessary, and the water supply pipe 27 can reinforce both side walls 2b. Is configured.

[Other Embodiments] To form the receiving housing 13 for washing the crop with the rotating brush 12, the rotating brush 12 is used.
The arrangement of can be changed appropriately. A specific configuration in which the crop discharging tool 17 is reciprocally movable can be appropriately selected, and a driving configuration for moving the crop discharging tool 17 to the discharge port 19 side while the rotary brush 12 is driven and rotating is, for example, a rotary brush driving motor 22. It may be a forward / reverse and stop switching operation unit or the like that is interlocked with, and these drive configurations are collectively referred to as drive units 18 and 24. The drive units 18 and 24 of the crop discharger 17 may be of a manual operation type or an automatic operation type, and may be configured such that, for example, when the cleaning process is completed by a timer, the discharge process is automatically executed. In the discharging process, the crop cleaning device 1 may be configured to be tilted by the drive device so that the discharge port 19 side becomes lower. The target for supplying the cleaning crop from the crop cleaning apparatus 1 is not limited.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
