Next, the operation will be described. Move the fuselage forward, and the reaper 3
The harvested cereals are supplied to the threshing room 10 by the cereal culm supply and transport device 46, threshed by the handling drum 11 rotating in the threshing room 10, and the threshed grains are handled by the handling net 1.
2, falls on the transfer shelf 20 of the swing sorting shelf 18 and is transferred by the transfer protrusion 19 of the transfer shelf 20 to be transferred to the wind selection chamber 1.
6, on the sheave 21 of the swinging sorting shelf 18, the swaying sheave 21 and the blast from the blower Karin 13 separate the straw chips and the grains, and the grains fall from the gaps of the sheave 21. It is taken out of the machine from the conveyor 23 first. in this case,
The swing sorting shelf 18 is divided into a starting end portion 29 of the transfer shelf 20 portion and a terminating side portion 30 where the sheave 21 is mounted, and the starting end portion 29 and the terminating side portion 30 are separately formed of synthetic resin. Therefore, each can be molded by another mold, and the mold can be reduced in size to reduce the cost required for manufacturing the mold.

Further, since at least the start end portion 29 is formed of a synthetic resin having excellent wear resistance, the durability is improved. In this case, since the start end side portion 29 and the end side portion 30 are separately formed of a synthetic resin, the start end side portion 29 is made of a synthetic resin having excellent wear resistance.
0 is easy to mold with a general synthetic resin, and also in this respect, the performance can be improved by using different materials without increasing the cost. Further, the terminal side portion 30 can be elastically deformed to some extent, and by utilizing this, the left and right side plates 35 of the terminal side portion 30 are expanded left and right, and in this state, the mounting shaft portion 40 and the adjustment shaft portion of the sheave 21 are adjusted. 41 is inserted through the mounting hole 39 and the arc-shaped long hole 42 for mounting, thereby facilitating the mounting operation. In particular, since the end side portion 30 is formed by the left and right side plates 35 and the bottom plate 36, a cutout portion 37 is formed on the rear side of the bottom plate 36, and the separation net 38 formed separately is attached to the cutout portion 37. The left and right side plates 35 are spread to the left and right and become cheaper,
The attachment of the sheave 21 becomes easy.

Further, since the separation screen 38 formed separately is attached to the terminal side 30, the cutout 37 of the terminal side 30 at the portion where the selection screen 38 is to be attached can be enlarged, and as a result, the area of the selection screen 38 can be increased. Can be widened to improve sorting accuracy and sorting efficiency. Thus, the threshing target material that does not fall from the handling net 12 enters the dust processing chamber 26 through the communication port at the end of the threshing chamber 10, and is processed and processed by the dust processing blade of the rotating dust processing cylinder. The kernels fall down from the dust treatment net and are selected by air in the air separation chamber 16. Straw and the like that does not fall from the dust treatment net fall from the dust outlet and are wind-selected to be straw waste. The kernels fall and the waste is discharged outside the machine. In addition, since straw waste does not fall from the gap of the sheave 21,
By the swinging of the swinging sorting shelf 18 and the blowing of the air blower 13, the air moves to the discharge side, and at the end side of the wind selection chamber 16, dust and straw chips are sucked and eliminated by the suction and dust fan 25, and the suction and dust fan 25. The straw waste that is not sucked up reaches the straw rack 22, and the straw waste that does not fall from the straw rack 22 is discharged outside the machine.

The spikes, spikes attached to the branch and the like, which have fallen due to the swinging of the swinging sorting shelf 18, are collected by the second conveyor 24, and are secondly processed from the end of the second conveyor 24 by the second object returning device 28. In the second processing chamber 27, the second product is removed by the second processing blade of the rotating second processing cylinder.
The processed grain and the second processed material are dropped on the transfer shelf 20 of the oscillating sorting shelf 18 from the second processed material discharge port. , Again sorted by rocking and wind. And threshing room 10
The thresh inside falls and collects on one side in which the second processing chamber 27 is provided by the action of the centrifugal force that rotates together with the gravity and the rotation of the handling cylinder 11. Since the end (start end) 32 is located on the right side and the upright moving plate 34 is provided so as to be inclined on the left side as it reaches the end side of the transfer shelf 20 in the transfer direction, the transfer shelf 20 swings. Due to the action of the pulling plate 34 and the right side (the side opposite to the grain culm supply and transport device 46)
The thresh that has fallen and collected on the left
6), and can be supplied while being diffused in the width direction of the wind selection chamber 16, thereby improving the sorting efficiency and accuracy in the wind selection chamber 16.

In this case, if the shift plate 34 is formed integrally with the transfer shelf 20 by using a synthetic resin, manufacturing and assembling becomes easy, and the lower surface of the shift plate 34 can be easily brought into close contact with the transfer shelf 20, so that it is ensured. Let it work. However, since the total length of the swing sorting shelf 18 in the swing direction is determined by the mounting space in the machine body, even if the swing sorting shelf 18 is divided into a start end side portion 29 and an end side portion 30, it is natural. While the start side 2
9 and the end side 30 are fixed to the entire length of the swing sorting shelf 18, but the length of the start end 29 and the end side 30 is determined by the mounting space, the first conveyor 23 and the second conveyor. Since the setting can be made in consideration of the arrangement of 24 or the air volume (wind power) of the air blower 13 and the like, the length ratio of the start end portion 29 and the end side portion 30 is changed in consideration of these conditions. Performance can be improved. However,
Making several types, selecting and installing them costs a lot. In view of the mounting space, the arrangement of the first conveyor 23 and the second conveyor 24, or the air volume (wind force) of the air blower 13 and the like, the length ratio is formed to the maximum common promise, and the separately formed sub-transfer shelf 43a is formed. By attaching and detaching to the start end side of the end side part 30, the swing sorting shelf 18 with good performance can be constituted without increasing the cost too much, and the mounting space and the arrangement of the first conveyor 23 and the second conveyor 24 are also reduced. validate.

In this case, the transfer shelves 20 are added to the sub-transfer shelves 43a.
Since the closing plate 34 is provided so as to follow the closing plate 34 provided at the end of the transfer shelf 20 and the start end side of the closing plate 34 is overlapped with the end of the transfer shelf 20, the closing plate 34 is reliably operated, and not only the transfer is performed. And improve the wind selection performance. A vertical engagement groove 45 is provided at the end of the approach plate 34 on the start end side portion 29 side.
If the starting end of the shift plate 34 of the sub-transfer shelf 43a which can be freely attached to and detached from the sub-transfer shelf 43a is fitted from above, the mounting becomes easy, and the shift plate 34 of the transfer shelf 20 and the sub-transfer shelf 43a
The step (corner) of the overlapping portion with the approach plate 34 is reduced, and the catch of straw or the like is reduced. Further, when the sub sheave 43b is replaced and used in place of the sub transfer shelf 43a, it becomes more effective.

[0021]
