Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a bottom-handling type threshing machine that is mounted on a combine harvester or a harvester, or used as a stationary type.

(b) Prior art In conventional threshing machines, the handling barrel is pivotally supported on a fixed machine frame, the receiving net is taken out laterally, and the oscillating sorting body is housed in a disassemblyable side wall. Ta.

(c) Problems to be solved by the invention In the above-mentioned known sub-handling type thresher, when removing clogs in the handling chamber or performing maintenance inspections, the handling cylinder was pivotally supported on the fixed machine frame, so the handling cylinder could become obstructed. When performing maintenance and inspection on the oscillating sorter, it is difficult to do the work simply by removing the receiving net, and the operation space is too small if only the window cover on the side wall is removed, and the oscillating sorter must be removed. It was not possible to carry out maintenance inspections under such conditions.

(d) Means for solving the problem The present invention is a threshing block by dividing the frame body that pivotally supports the handling drum into front and back parts at the back of the handling room, and rotating the threshing block around the upper part of the divided part. The receiving net in the handling room is attached to the frame body to form a receiving net block, and this receiving net block is removably attached to the machine frame. The sorting body is screwed onto the swing arm so that it can be attached and detached from above, and the threshing block can be rotated upward or removed to open the handling chamber to expose the receiving net. The above-mentioned problem was solved by removing the receiving net block in this state so that the upper surface of the oscillating sorting body was exposed.

(e) Effect When performing maintenance and inspection on the handling room, the upper part of the receiving net is opened wide by raising and rotating the threshing block or removing it, and if the receiving net block is removed in this state, the upper part of the oscillating sorter is opened. can be opened, and the swinging sorter can be removed from this opening.

(F) Example An example of the present invention will be explained with reference to the drawings.
The threshing block A is composed of side walls 1, 1, a top plate 2 and a front plate 3 that connect these side walls, and a handling cylinder 4 that is mounted between the side walls 1, 1 by a handling cylinder shaft. The side walls 1, 1 and the top plate 2 are divided into front and rear parts at the back of the handling room, and the divided part of the top plate 2 is rotatably connected with hinges 5, 5, and the overlapping part of the side walls 1, 1 is The receivers 6, 6 are removably screwed together with butterfly bolts 7, 7, and the threshing block A can be removed when the screwed portions are removably connected.

In addition, the receiving net 8 is stretched over a receiving net frame 11 that fits into the inner surfaces of the machine walls 1a, 1a that constitute the lower edges of the supply port 9 and the discharge port, and the receiving net block is constructed as shown in FIG. B, and is detachably attached with bolts 12.

Furthermore, an oscillating sorting body 13 provided below the receiving net 8
is composed of a transfer plate 13a and a sorting net 13b, and its front part is mounted on swing arms 15, 15 loosely fitted to eccentric wheels 14, 14, and its rear part is mounted on swing arms 16, 16.
It is removably screwed onto the top with a bolt 17 inserted from above.

A feed chain 18 is stretched over the front plate 3 of the threshing block A, and a pinch rail 19 is attached to the front surface of the receiving net block B via a bullet by a receiving plate 20, and the sorting net 13b A first receiving gutter 21 is provided below, and a second receiving gutter 23 is provided behind it, and a second thrower 24 with a discharge port opening into the handling chamber is provided at the transfer end of the second receiving gutter 23. A blowing fan 25 provided below the handling port and a suction fan 26 provided above one side of the dust evacuation chamber constitute a sorting air path.

Next, the transmission device will be explained with reference to FIG. 4. The shaft of the blower fan 25 is driven by the power of the engine, and the belt 3 is connected to the pulley 26 of the shaft, the second transfer spiral pulley 27, and the counter pulleys 28 and 29.
The three-stage counter pulley 28 drives the suction fan pulley 32 via the belt 31 and the threshing pulley 34 via the belt 33, and the feed chain 18 is attached to the handling barrel shaft. It is driven by a shaft equipped with a worm, a worm gear meshing therewith, and a drive sprocket, and the swing pulley 35 and the helical pulley 36 are driven by the counter pulley 29 via a belt 37.

In the above-mentioned threshing machine, the grains being threshed and small straw waste generated in the handling chamber by threshing the supplied grain culm are leaked from the receiving net 8 to the swinging sorter 13 and are transferred. The grains that have leaked out from the sorting net 13b are sorted by wind and sent to the first receiving gutter 2.
1 and thrown from the end of the sorting net 13b are further screened, and the second items are transferred to the second thrower 24 by the second transfer spiral in the second receiving gutter 23 and then to the handling room. The straw that is thrown back and the dust inlet 23
The dust from a is sorted by air and discharged to the outside of the machine by a suction fan 26.

Therefore, when removing straw debris stuck in the handling chamber, or when performing maintenance and inspection of the handling room and receiving net 8, etc., the butterfly bolts 7... are removed and the threshing block A shown in Fig. 2 is removed. When the net is rotated 180 degrees upwards, the upper surface of the handling chamber is opened to the extent that the entire receiving net 8 is exposed, so that maintenance and inspection can be easily carried out without obstacles such as the handling cylinder 4 or the feed chain 18. can be done.

In addition, when maintaining and inspecting the receiving net 8 itself or various devices below it, the receiving net 8 can be maintained externally by removing the receiving net block B, and the pinching rail 19 can be maintained.
Also, the swinging sorter 13 can be maintained without the receiving net 8.

Furthermore, by removing the bolts 17 with the receiving net block B removed, the swinging sorting body 13 can be removed, making it possible to easily maintain and inspect the swinging mechanism and other devices located below.

In addition to the above-mentioned transmission device, FIG. 4 also shows the installation structure of the receiving net 8, in which the arc-shaped upper surface plate b of the receiving net block B has a cutout window 38 that is slightly smaller than the receiving net 8. , a receiving net 8 is placed on the cutout window 38, and a plurality of band-shaped corrugated plates 40a are placed on each side edge of the receiving net 8,
Furthermore, the pushers 40 are superimposed on the upper surface, and the bolts 42 are inserted through the holes 41 of these pushers 40 and tightened into the screw holes 43 on the periphery of the cutout window 38, thereby closing the receiving net 8. is removably attached to the receiving net block B, so when the objects to be threshed are different, such as rice, wheat, soybeans, and other grains, receiving nets 8 with different mesh sizes can be selected and easily replaced. If the sorting net 13b is replaced accordingly, the swing sorting body 13 can be removed.

(g) Effects of the invention Since the invention is constructed as described above, when the threshing block A is rotated upward or removed, the entire upper part of the receiving net 8 becomes open, which obstructs maintenance and inspection of the handling room. It can be done easily, quickly and safely without any objects.

Moreover, when the receiving net actuator B is removed,
Of course, it is possible to maintain or replace the receiving net 13b with the receiving net 13b taken out of the machine.
Maintenance and inspection of the various devices located at the bottom of 3 can be easily performed in an open state.
