Description

  The present invention takes in root crops such as onions and potatoes, or crops such as fruits grown on vegetation, and sorts crops such as root vegetables and fruits by workers riding on the aircraft, so that soil, sand, defective products, The present invention relates to an agricultural machine that discharges leaves and the like and collects good crops in a collection box.

  Conventionally, after picking up crops such as onions and potatoes from the field soil with a harvesting farm work machine and placing them on the field top soil for drying, the farm picks up the equipment while running the crops provided in front of the farm work machine for collecting the crops. And pick it up and feed it to a pallet circulation conveyor arranged in a square shape at the rear. On the other hand, the worker sits on a chair provided on the machine body and sorts the crops from the crops, earth and sand, etc. sent by the round pallet circulation conveyor. It was dropped from the pallet and collected. In addition, a part of the plant body of soil blocks, sand, stones, defective crops, leaves and stems mixed with agricultural products on the pallet circulation conveyor is removed from the pallet and discarded. These agricultural machines and their working methods are disclosed in Patent Documents 1 and 2.

However, in the inventions of Documents 1 and 2, the good products collected by the round-shaped circulation conveyor are inclined by forcibly lowering the outside of the pallet at the conveyor side before the circulation conveyor makes a round, It falls outside and collects in a lower collection box.
However, if the circulating horizontal pallet is tilted so that the outer edge is downward at the falling edge, the crop is sandwiched between the horizontal pallet in front and the tilted pallet, and the crop is damaged without falling. It was damaged or hindered the smooth circulation movement of the circulation conveyor. Further, since there is a crop fall space, a collection box, and a roller conveyor for taking in and out the crop box, the driver's seat or the operator's chair cannot be arranged on this side.

  In addition, if the crops on the conveyor are insufficient, it is difficult to circulate again, and it is necessary to finish the crop processing work that needs to be sorted in one round. There was.

The problem to be solved by the present invention is to reliably collect crops so that they are not caught in the fall of crops collected and to circulate the circulation conveyor smoothly.
Another issue is that the worker's chairs are placed on the three sides of the round-shaped circulation conveyor so that the three workers on the three sides can sort and discharge the waste and operate the machine. It is to be able to efficiently perform these operations while traveling in the field.
Next, crops falling from the circulation conveyor are accommodated in a collection box with little drop impact and few scratches.
Furthermore, it is to secure a loading space for the empty box of the collection box and to prevent the installation column from hindering the work of the operator.

The configuration of the present invention that solves this problem is as follows.
1) A plurality of horizontal pallets on which root vegetables or fruit crops are placed on the upper surface are connected to the aircraft that can run in the field, and the connected planar arrangement is connected in a square shape and each pallet is placed. A pallet circulation conveyor having a structure for driving so as to circulate and move along the square shape is provided, and a crop carry-in conveyor for feeding the crops onto the pallet of the pallet circulation conveyor is provided. In an agricultural machine with a plurality of chairs on the fuselage on the outside of the pallet circulation conveyor, the worker's chair performing the sorting work of the crops, the waste removal work or the crop processing work,
A box installation that supports the crop collection box below the inner space surrounded by the pallet circulation conveyor and holds the collection box horizontally from the lower side of the square pallet conveyor to the outside of the square area. A farm work machine 2) provided with a device, and provided with a crop feeding device for dropping a crop on the pallet into a collection box below the inner space in the middle of the pallet circulation conveyor. A belt conveyor with a substantially vertical surface is arranged so that the feed direction of the crop on the top of the pallet circulation conveyor and the belt feed direction of the belt conveyor are diagonally crossed, and the crop on the pallet is pallet-circulated on the belt surface of the belt conveyor. Agricultural work machine described in 1) above, which is structured to be guided to the inner space of the conveyor. Is a structure that can be switched by manual switching means to two positions, a position that is oblique to the feed direction of the pallet circulation conveyor and a retreat position that does not obstruct the passage of crops on the pallet. Agricultural machine 4) The belt conveyor has a frame angle in which one end of the frame is pivotally supported outside the conveyor path of the pallet circulation conveyor, and the belt surface is oblique to the feed direction of the pallet circulation conveyor, and the belt conveyor. Agricultural working machine 5) according to the above 3), comprising a holding means capable of manually switching the belt surface of the belt to the frame angle at the retreat position outside the conveyor path of the pallet circulation conveyor and holding the frame at the angular position. The belt conveyor has a plurality of brushes attached to the lower end of the belt, which sweeps the upper surface of the pallet passing below, with a predetermined distance between them, ) Agricultural implement 6) Any one of the above-mentioned crop feeding devices provided with a drop guide for guiding the crops so that the crops guided inward from the pallets fall into the collection box at a position inside the pallet circulation conveyor. The farm working machine according to any one of 1) to 5) 7) A farm product is a farm product that has been dug out of a field, placed on the field top soil and dried, and the farm product carry-on conveyor picks up the farm product on the field table It exists in the farm work machine in any one of said 1) -6) which is a crop picking-up apparatus.

  According to the present invention, the collection box is disposed below the center of the pallet circulation conveyor, the feeding conveyor is disposed, and the good products of the crops on the pallet circulation conveyor are fed downward to the center. Compared to the space that needed to drop crops and the collection box in the outer space, the central space was used to place more chairs for workers to sit in the outer area of the pallet circulation conveyor. It was possible to perform sorting work and waste removal work around the long outside. The operator's work area can be expanded, so that the work ability can be increased and the speed of the aircraft can be increased.

Also, in the structure where the ceiling shelf is held by the inner support column above the fuselage, the support is provided on the inner side, eliminating the conventional disadvantage that the operator has conventionally restricted manual work by contacting the outer support column. This makes it easier to perform manual work over a wide range without any manual obstacles.
In addition, since a ceiling shelf is provided on the top of this support column, an empty collection box can be stacked on this ceiling shelf, and the collection box filled with agricultural products is discharged outside and left on the field. Since the empty collection box on the ceiling shelf is placed in the box installation device inside the pallet circulation conveyor, it can be quickly installed because it is above the same machine body.

  Furthermore, if a belt conveyor is used as the crop feeding device and it can be manually switched between a pallet circulating conveyor pallet feeding direction and a retreat position, it is possible to select crops and eliminate waste. If the work is inadequate, it is possible to easily increase the time or work quality of the manual processing by further rotating the pallet circulation conveyor one or two times for the crop.

In addition, when a belt conveyor is used for the crop feeding device, and a plurality of brushes are attached to the belt surface of the belt conveyor at a predetermined pitch, the brushes together with the belt remove soil, sand, and small soil blocks remaining on the top surface of the pallet. Sweep diagonally from outside to inside to clean the top surface of the pallet.
This prevents soil-covered crops from being transported on the surface of the pallet, and the soil, mud, and plant fragments remaining and gradually becoming a large amount by sweeping them to the inside of the pallet at the position of this belt conveyor, The top surface of the pallet prevents soil and sand from accumulating. Further, the crops of the brush slide with the belt surface to forcibly move crops that are difficult to move inward.

  Further, the crop carrying conveyor of the present invention is a crop picking device, and an endless slat conveyor whose front end is lightly stabbed into the field at the front thereof, and the left and right sprockets above the endless conveyor using the conveyor bar (slat) In the case where the extruded member is installed between the grooves for locking the bar material, the adhering / fixed material of the conveyor bar material (slats) of stone, soil, and plant pieces in the upper sprocket part of the endless belt can be eliminated, Preventing the endless slat conveyor pick-up function from being lowered and ensuring the fall of sand and sand is eliminated.
