This vertical conveying body 14 has a starting end sprocket 19 at the lower end located at the lower end of the lower conveying device 11, and a terminal end sprocket 20 at the upper end located at the spanner rod 1 disposed along the foot chain 5.
They are supported by support stands 32 provided on the upper surface of the fuselage 1 so as to be located at the starting ends of the fuselage 1.

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

On the other hand, reference numeral 36 denotes a cross-sectional bracket attached to the upper surface of the support base 32 with bolts 37, and at its upper end there is a guide member 38 equipped with two guide tubes 39, 40 in parallel with the bolts 41.
When the guide body 38 is stopped, the axes of both guide tubes 39 and 40 are tilted rearward by an appropriate angle θ with respect to a direction perpendicular to the direction of movement of the combine when viewed from above, and the guide body 38 is tilted at an appropriate angle θ from the front side of the combine. It is configured to be inclined diagonally upward by an appropriate angle α with respect to the horizontal line when viewed from the pre-reaping processing unit.

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
, 40, and is configured to reciprocate laterally with respect to the direction of movement of the combine by means of a hydraulic cylinder 45 installed parallel to the combine harvester.

In this case, the piston 46 of the hydraulic cylinder 45 has a screw rod 47 connected thereto fitted into a boss 43' integrally formed on the transmission case 43, and nuts 48, 4 screwed onto the screw rod 47.

The chino 58 is transmitted to the shaft 51 of the.

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 into the hollow shaft 59 is fixed, and the base end of a hexagonal shaft 600 slidably inserted into the hollow shaft 59 is connected to the output shaft 62 of the transmission mechanism 61 attached to the fuselage 1. They are connected via a universal joint 63.

The safety pin 64 that connects the end sprocket 20 and its shaft 57 is provided within the annular groove 20' of the sprocket 20, and is configured to be wrapped with straw to prevent any damage.

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, the 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 then conveyed and then fed between the foot chain 5 and its clamping rod 16 through the 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 from side to side in a plan view, that is, if the culm is long, the end of the longitudinal conveyor Q is moved to the side, and if the culm is short, it is moved inward. This allows the handling depth to be uniform.

When moving the upper part of the vertical conveying body 14 left and right according to the length of the culm, in the present invention, the upper part of the vertical conveying body 14 is supported by two pieces, a sleeve 42 and a guide shaft 44, so as to be able to reciprocate left and right. Therefore, the weight of the vertical transport body 140 is divided into both parts, so it has high rigidity and can withstand a large load.
Moreover, since the cylinder 45 is disposed between the sleeve 42 and the guide shaft 44, there is no twisting when the vertical transport body 14 is moved by the operation of the cylinder 45, and the cylinder 45 is disposed between the sleeve 41 and the guide shaft 44. Since the weight of the vertical transport body 140 does not act on the cylinder 45, the cylinder 45 can reciprocate from side to side with a light force and can be done extremely smoothly. Since the sleeve 42 and the guide shaft 44 can be set arbitrarily, the sleeve 4
As shown in FIG. 4, the axes of the vertical conveyor 14 and the guide shaft 44 are tilted at an appropriate angle θ rearward with respect to a direction perpendicular to the traveling direction in a plan view of the combine, so that the terminal end of the vertical conveyor 14 is tilted in this angular direction. By moving the culm to overlap the foot chain 5 when the culm is long, or by moving the axes of the sleeve 42 and guide shaft 44 to the horizontal line when viewed from the front of the combine as shown in FIG. By tilting it diagonally upward by an appropriate angle α,
The upper part of the vertical transport body 14 is attached to the foot chain 5 as shown in FIG.
It is possible to arbitrarily move it along the inclination direction of one surface.

Furthermore, since the power transmission shaft for driving the chino of the vertical transport body is built into the sleeve 42, the structure is simpler than when the transmission shaft is provided outside the sleeve, and the rotating part does not protrude outside. Therefore, it also has the effect of being safe because the workers do not have to touch their hands or feet.

By configuring the cross section of the vertical transport body 14 perpendicular to the longitudinal direction to be inclined diagonally outward and forward at an appropriate angle β, as shown in FIG. 4, instead of being parallel to the traveling direction of the combine as in the conventional case , the lower conveying device 11 forces the culm to the vertical conveying body 14, and the joint becomes smooth.
By independently supporting both the upper and lower ends on the support stand 32 as in the above-mentioned embodiment, the vertical conveyance device can be made into a unit, and assembly into a combine harvester, repair and inspection, etc. can be easily carried out. Hole 37' of bolt 37 for mounting bracket 36 to 32 and inductor 38 to bracket 36
The holes 41' for the mounting bolts 41 are formed in each column length slot, etc., so that the bracket 36 can be adjusted horizontally.
It is also possible to arbitrarily adjust the relative positions of the end of the vertical conveyor 14 and the foot chain 5 in the vertical and longitudinal directions, as well as the inclination angles θ and α. It is.
