14 is a swinging sorting shelf of the sorting section 4, and the mounting structure of the swinging sorting shelf 14 is the gist of the present application. The right frame 15 and the wooden frame 16 of the swinging sorting shelf 14 are formed to have a length of about a cup in the front and back direction of the threshing section 3.

As shown in FIGS. 3 and 4, the swinging sorting shelf 14 is formed into a substantially rectangular profile. On the front side of the swinging sorting shelf 14, a transfer shelf 17 for transferring the grains falling from the handling net 9 rearward is provided, and on the rear side of the swinging sorting shelf 14, a straw rack 18 in the front-rear direction is provided. A sheave 19 in the left and right direction is provided between the transfer shelf 17 and the stroke rack 18. The sheave 19 is rotatably fixed to the right frame 15 and the wooden frame 16 by a shaft 20.

At the rotating end of the sheave 19, there is an arc hole 2 formed in the right frame 15.
A pin η is provided which projects outward through the pin η, and the respective protruding ends of the pin η are connected to each other by a connecting rod n in the front-rear direction. Therefore, when the connecting rod n is moved in the front-back direction, the sheave 1
9 rotates around the shaft, and the inclination angle can be adjusted freely.

Reference numeral 24 denotes an intermediate lever, and the pin η is fixed at the center thereof, and the shaft is fixed at the upper rotating end thereof.

The lower rotating end of the intermediate lever 24 has one end of the rod δ as its axis. A spring 58 is provided between the intermediate lever 24 and the right frame 15, and biases the intermediate lever 24 in the counterclockwise direction. The other end of the rod b is pivoted to the pivot end of the pivot lever 26.The base of the zero pivot lever is rotatably fixed to the right frame δ by a pivot shaft n. As shown in FIG. 3, it extends below the transfer shelf 17 between the right frame 15 and the wooden frame 16, and the cam body n is fixed at the center thereof. Therefore, when the cam body rotates, the connecting rod n moves in the front and back direction,
The inclination angle of the sheave 19 is set to gR.

A roller n is attached to the cam body 4 as desired.

A roller body 30 and a roller body 31 are pivotally fixed to the outer front sides of the right frame 15 and the wooden frame 16, respectively.

Reference numeral 32 denotes a swinging bracket that is detachably fixed to the left and right frames 15 and 16 by a shaft, and a rotating shaft U is fixed to the base end of the swinging bracket η. 35 is a pulley of the rotating shaft 34, and this pulley is connected to the motor via a bell 36. This configuration becomes a swinging mechanism.

Therefore, on the left wall g and right wall wing of the threshing section 3 and the sorting section 4, there is a long substantially horizontal left guide rail 39 and a right guide rail 4 before and after the roller bodies (9) and the roller bodies 31 are transferred, respectively.
0, and a U-shaped left inclined groove 41 and a right inclined groove 42 are connected to the front end of the left guide rail blade and the right guide rail 40,
Or formed separately.

Therefore, the swing sorting shelf 14 has a roller body (9) on the front side;
31 and the inclined grooves 41 and 42, the rear side is supported by the left and right walls g and 38, respectively, by the swinging mechanism.

43 is an upper link that is axis W to the frame 1 via a shaft 44, 45 is an L-shaped lower link that is axis W to the frame 1 via an axis 46, and 47 is a rotation of the upper link 43 and the L-shaped lower link 45. This is a connecting link that connects the moving ends, and the upper link 43, the L-shaped lower link 45, and the connecting link 47 constitute a parallel link 4B. An abutting plate 49 is fixed to the E end of the connecting link 47. The corresponding contact plate 49 has an angular shape, and the cam body n is attached to the front inclined part of the corresponding contact plate 49.
bring it into contact.

The angle of inclination between the front inclined parts is the same as the angle of inclination of the inclined grooves 41 and 42. This point is also an important gist of the present application. The angle of inclination of the rear inclined portion 51 is arbitrary. L
One end of a wire 52 is locked to the other rotating end of the mold lower link 6, and the other end of the wire 52 is locked to an operating lever provided on the driver's seat 7.

54 is the blower fan, 5 is the first gutter, my father is the second gutter, 57
is a suction fan. (Function) Next, the function will be described.

As described above, the present invention is a 9-hour shaking sorting shelf! 4 colo body 30
, the roller body 31 is tilted to the left y441. Since it is movable with respect to the right inclined groove C, the swinging bracket can be moved by the rotating shaft (32).
When rotated, the swing sorting shelf 14 as a whole swings obliquely up and down and back and forth along the inclination angle of the inclined grooves 41 and 42.

When reaping and threshing work is performed in this state, the husk harvested by the reaping section 5 is sent to the threshing section 3 by the culm conveying device W16, is threshed in the threshing section 3, and falls from the handling net 9. The grains are received by the transfer shelf 17, transferred to the rear, and fall onto the first receiving gutter, where they are taken out of the machine.The waste from the dust removal cylinder falls onto the sheave 19, and - long grains are collected. The long items fall onto the - number receiving gutter 5, and the second items fall onto the second receiving gutter 5 and are reprocessed.

Therefore, when sorting using the sieve 19, the width of the gap of the sieve 19, that is, the angle of inclination, is adjusted to 14 mm depending on the size of the straw.
Good sorting can be done by making a knot.

That is, when the wire 52 is pulled by the operating lever and the connecting link 47 is moved upward, the front inclined portion of the abutment plate 49 pushes up the cam body and rotates the rotation axis n. Move the rod δ to the left by levering the lever, and move the intermediate lever 24.
rotates around the shaft, moves the connecting rod n to the left, rotates and tilts the sheave 19 attached to the connecting rod n via the pin η, and narrows the gaps between the sheaves 19. When the abutting plate 49 is moved downward by the operation lever 8, the cam body 28 is urged in the downward direction by the spring group, so the abutting plate 0 rotates in the opposite direction by the amount that the abutting plate 49 has moved downward, and the connection is completed. Move the rod n to the right to widen the gap between the sheaves 19.

Therefore, as described above, the gap between the sheave 19 and the cam body 2
8, but since the inclined grooves 41 and C and the front inclined part of the contact plate 49 are formed at the same angle, even if the swinging sorting shelf 14 swings, the cam Since the body 28 only slides on the upper surface of the front inclined portion and does not rotate once, the gap between the sheaves 19 does not change.

When the swinging sorting shelf 14 is removed from the machine for maintenance and inspection, the swinging bladder 9 is removed from the shaft and the swinging sorting shelf 14 is pulled rearward in this state. (9) The roller body 31 moves rearward while moving along the left inclined groove 41, the right inclined groove 42, the left guide rail blade, and the right guide rail cut, and the cam body 4 and the contact plate 49 move backward. Since this is a contact connection, the cam body n can move rearward over the front inclined portion of the contact plate 49, and the swing sorting shelf 14 can be removed from the machine body with great ease.

When attaching the swing sorting shelf 14 that has undergone maintenance and inspection to the aircraft, place the roller bodies 31 between the roller bodies of the swing sorting shelf 14 on the left guide rail and the right guide rail, and push them forward. The roller body (9) is guided by the left guide rail vane and the right guide rail blade, and the roller body 31 engages with the left inclined groove 41 and the right inclined groove C, and the cam body n engages with the abutting plate 49. Because the sheave 19 is pushed out in one direction by contact with the rear inclined portion 51 and then contacts the front inclined portion (material), the inclination angle of the sheave 19 is constant depending on the position of the contact plate 49, and the inclination There is no difference between the angle and the display of the operating lever lever, and the operation can be performed extremely easily simply by attaching the swing bracket 32 to the shaft vane.

(Effects) In the known inclination angle adjustment mechanism, the other end of the wire connected to the operating lever was directly connected to the sheave. Therefore, when removing the swinging sorting shelf from the aircraft,
It is necessary to disconnect the sheave and the wire, and when the swing sorting shelf is inserted, it is necessary to connect the sheave and the wire, which is a troublesome operation.

In other words, dimensional accuracy is required when attaching and detaching the wire.
Even if there is a slight deviation, the inclination angle of the sheave and the display on the operating lever will not match, which will hinder the sorting work.

However, the present invention provides a swing sorting shelf 1 having a sheave 19.
4 is removably attached to the sorting section 4, and the sheave 1
Reference numeral 9 denotes a threshing machine whose inclination can be freely adjusted via a wire 52 by operating an operating lever 53 provided on the machine body side. A contact plate 1 is provided on the machine body side that changes in height by operating the control lever group, and when the swing sorting shelf 14 is inserted into the machine body side.

Since the cam body 4 is designed to adjust the sheave angle of the swing sorting device in the threshing machine in contact with the contact plate 48, the machine body and the swing sorting shelf 14 have a removable structure, but the sheave angle 19 and the wire 52 do not need to be attached or detached, so the swing sorting shelf 14 can be easily attached and detached, and the inclination angle of the sheave and the display on the operating lever are more consistent than in the conventional case.
