Further, reference numeral 28 denotes a guide piece 28 which is rotatably fixed to the upper end of the support rod 24 of the clamping rod 23 and is also used for shortcuts.
is attached to the back of the support rod 24 at the bar 30.
1, and the upper surface of the fork is formed so that the distal end does not protrude beyond the chain feed pawl 22 and the base end protrudes beyond the chain feed pawl 22.

Note that 31 indicates a piece of shell culm 41 attached to the guide frame 18.

This vertical conveying body 14 is arranged such that the starting end sprocket 19 at the lower end thereof is located under the terminal end of the lower conveying device 11, and the terminal end sprocket 20 at the upper end is located at the starting end of the clamping rod 16 disposed along the foot chain 5. It is supported by a support stand 32 provided on the upper surface of the fuselage 1.

That is, by connecting the shaft 33 protruding from the front side of the support stand 32 in the direction of movement of the combine to the shaft 34 attached to the cheno guide frame 18 via the crank 35,
The lower part of the vertical transport body 14 is supported rotatably in the vertical direction.

On the other hand, 36 is a cross-sectional bracket attached to the upper surface of the support base 32 with bolts 37, and at its upper end, a guide member 38 equipped with two guide tubes 39 and 40 in parallel is attached to the poles 1-4.
1 is stopped, and the axes of the guide tubes 39 and 40 of the guide body 38 are inclined rearward by an appropriate angle θ with respect to a direction perpendicular to the direction of movement of the combine in a plan view of the combine, and (when viewed from the pre-reaping processing section), at an appropriate angle α diagonally upward with respect to the horizontal line.
It is configured to tilt only.

Reference numeral 42 denotes a sleeve that is slidably inserted into the upper guide tube 39 of the induction body 38, and the conduction case 43 fixed to the tip thereof is a guide shaft that is slidably inserted into the sleeve 42 and the lower guide tube 40. 44, both guide tubes 39
．． A hydraulic cylinder 45 installed parallel to the combine harvester 40 is configured to reciprocate laterally with respect to the direction in which the combine harvester moves.

In this case, the piston 46 of the hydraulic cylinder 45 has a screw rod 47 connected thereto, which is fitted into a boss 43' integrally formed on the transmission case 43, and is screwed onto the screw rod 47.48.
48 and are adjustably connected.

Further, 49 is a chain guide frame 18 of the vertical conveyor 14.
The case 49 and the conduction case 43 have support tubes 43" and 4 protruding from each of the case 49 and the conduction case 43.
9' are fitted and rotatably connected, and one end of the transmission shaft 50 provided inside is connected to the shaft 51 in the transmission case 43 with the bevel gear 5.
2.53, while the other end is transmitted to a shaft 54 in the chino case 49 by a bevel gear 55.56, from which the chino 58 is transmitted to the shaft 57 of the end sprocket 20 in the longitudinal conveyor 14. There is.

On the other hand, a sleeve 42 is attached to the shaft 51 inside the conduction case 43.
A hexagonal hole hollow shaft 59 rotatably inserted therein is fixed, and the base end of a hexagonal shaft 60 slidably inserted into the hollow shaft 59 is attached to an output shaft 62 of a transmission mechanism 61 attached to the fuselage 1. The hexagonal shaft 60 on the combine machine body side is inserted into and removed from the hollow shaft 59 on the vertical conveyance body 14 side, so that the vertical conveyance body 14 is connected to The power transmission section to the vertical transport body 14 and the power input section in the vertical conveyance body 14 are detachably connected.

A safety pin 64 connecting the end sprocket l-20 and its shaft 57 is provided within the annular groove 20' of the sprocket 20 to prevent straw from getting wrapped around it.

In this configuration, the power of the transmission mechanism 61 is transmitted from the hexagonal shaft 60 to the end sprocket 20 via the hollow shaft 59, shafts 51 and 50. Since the chain 21 wound around is driven in the direction of the arrow, the shell culm from the lower conveying device 11 is passed between the chain 21 and the clamping rod 23 at the starting end of the vertical conveying body 14, and is successively transferred. It is conveyed and then fed between the foot chain 5 and its clamping rod 16 from 20 end sprockets.

In order to make the handling depth constant depending on the length of the culm to be handled, the hydraulic cylinder 45 is operated to rotate the vertical conveyor 14 about the crank 35 at the bottom, and the end sprocket 20 is rotated between the foot chain 5 and the foot chain 5. The clamping rod 16 is moved to the left and right in a plan view, that is, if the culm is long, the end of the vertical conveyor is moved to the side, and if the culm is short, it is moved inward. This allows the handling depth to be uniform.

In this case, the lower part of the vertical conveyor 14 is rotatably attached to the support base 3z via the crank 35, while the upper part is attached to the support base so that it can move left and right with respect to the foot chain 5 by means of the induction body 38. 32, the lower part is attached to the support frame 7 of the pre-processing section 17 as in the conventional case.
The vertical conveyor body 14 is constructed into a unitized structure with a support structure independent from the pre-processing section and the threshing device, and is not attached to another member so that the upper part is attached to the threshing device 6 respectively. be done.

Furthermore, by removably connecting the power transmission section from the combine machine body side to the vertical conveying body 14 and the power input section in the vertical conveying body 14, the vertical conveying body 14 can be connected to the vertical conveying body 14.
4 also has an independent structure when transmitting power.

Therefore, in order to assemble this vertical conveyor 14 into a combine harvester,
First, after attaching it to the support stand 32 in the above-mentioned manner, place the whole support stand 32 on the combine harvester body 1, and then attach the support stand 32 to the combine harvester body 1.
It is sufficient to fix the unit to the machine body 1 with bolts or the like, and connect the power transmission part from the combine machine body side to the vertical transport body 14 and the power input part in the vertical transport body 14, and also remove the vertical transport body 14 from the combine. In this case, by uncoupling the power transmission section and the power input section and removing bolts etc. fixing the support base 32 to the machine body 1, the combine harvester can be removed at once.

According to the present invention, it is possible to extremely easily assemble the vertical conveying body to the combine harvester, and the vertical conveying body can be inspected and repaired safely and easily.
