Thus, the upper cover 7 extends rearward so as to surround the upper part of the straw conveying device 11, and in the working state, the inner surface of the upper cover 7 comes into contact with the flanges 24, When the transport chain 13 is brought close to the clamping rod 12 in opposition to the elasticity of the springs 25, 25, and the upper cover 7 is opened, the elastic chain of the springs 25, 25 clamps the straw transport chain 13. Rod
It is moved upward with respect to 12 (note that a cover surrounding the upper part of the straw conveying device 11 may be separately provided and opened and closed in conjunction with the upper cover 7).

FIG. 4 shows a transmission mechanism, and 26 is a shaft 27 of the drive gear 17.
, A bevel gear 28 meshing with the bevel gear 26, 29 a pulley fixed to the shaft 30 of the bevel gear 28, 31
Is a pulley fixed to the handle shaft 32, 33 is a belt, 34 is a bevel gear, 35 is a bevel gear meshing with a bevel gear 35, 36 is an input pulley, 37 is a bevel gear box of the bevel gear 26 and bevel gear 28, and the bevel gear box 37 Is configured to move up and down in accordance with the up and down movement of the straw transport chain 13.

In the figure, reference numeral 39 denotes a sensor for detecting a straw clog provided in the transfer section 38.

FIG. 5 shows a second embodiment, in which a contact member 40 is provided on the inner surface side of the upper cover 7 and when the upper cover 7 is closed,
When the contact member 40 comes into contact with the upper surfaces of the flanges 24, 24, the straw conveying chain 13 approaches the clamping rod 12 against the elasticity of the springs 25, 25, and the upper cover 7 is opened. With the elasticity of the springs 25, 25, the straw conveying chain 13 is moved upward with respect to the clamping rod 12. The abutting member 40 is formed of an elastic member so that the straw conveying chain 13 can freely move upward.
12 is fixed to the fuselage side.

In the above-described embodiment, the straw transport chain 13 is configured to move upward. However, the straw transport chain 13 may be configured to move laterally or to rotate around the shaft 27 of the drive gear 17.

(Operation) Next, the operation will be described.

Since the present invention is configured as described above, when the body is advanced, weeding is carried out by the weeding body 4, raised by the raising device, converged by the front spike transfer device and the front root transfer device, and automatically fed threshing device. 5 is taken over by the grain stalk supply device 8,
In the state where the tip is supplied to the threshing room of the threshing device 5,
The root is transferred by the culm supply device 8 and threshed.
It is supplied to 11 and transported backward by the straw transport device 11.

In the above case, when the amount of the threshed waste straw is large, the starting end of the straw transporting device 11 may be clogged.

In the present invention, the straw transport chain 13 of the straw transport device 11 is
The guide rail 16 of the straw conveying chain 13 is vertically movably attached to the cylindrical parts 23, 23 of the support arm 21 by the longitudinal parts 20, 20, and the upper ends of the longitudinal parts 20, 20 are provided with flanges 24, 24. Formed, said collar 24, 24
The springs 25, 25 are respectively provided between the longitudinal parts 20, 20 between the cylindrical parts 23, 23.
Is provided, the waste clogging detection sensor 39 detects the clogged waste of the transfer portion 38, and when the upper cover 7 is opened, the downward pressing of the flanges 24, 24 by the inner surface of the upper cover 7 is performed. The flanges 24, 24 are moved upward by the elasticity of the springs 25, 25, and the guide rail 16 is moved upward by the upward movement of the flanges 24, 24, so that the straw conveying chain 13 is raised with respect to the clamping rod 12. Move.

Therefore, only by opening the upper cover 7, the straw transport chain 13 is separated from the clamping rod 12, and the straw can be easily clogged and the straw removed.

Next, when the upper cover 7 is closed, the inner surface of the upper cover 7 comes into contact with the flanges 24, 24 and pushes down, and the straw conveying chain 13 is pressed against the clamping rod 12 against the elasticity of the springs 25, 25. As a result, the straw-carrying chain 13 approaches the pinching rod 12 and comes to the working position.

In the second embodiment shown in FIG. 5, a contact member 40 is provided on the inner surface side of the upper cover 7, and when the upper cover 7 is closed, the contact member 40 comes into contact with the upper surfaces of the flanges 24, 24, The straw conveying chain 13 is brought closer to the clamping rod 12 against the elasticity of the springs 25, 25, and the contact member 40 is formed of an elastic member, so that the straw conveying chain 13 can freely move upward. Because
When a large amount of straw is supplied to the start end of the straw transport chain 13, the straw transport chain 13 freely moves upward against the elasticity of the abutting member 40. And the transfer of the straw from the straw supply device 8 to the straw transport chain 13 is improved.

(Effect) Conventionally, a straw transporting device including a clamping rod for transporting threshed waste straw and a straw transporting chain provided on the upper side thereof is provided outside laterally of the handling cylinder chamber in which the handling cylinder is fixed to an axis, A straw conveying device of a threshing device in which an upper cover is provided above the straw conveying device is known.

When the amount of the threshed waste is large, the known thing may cause a clogging phenomenon at the start end thereof. When removing the clogged straw culm, since the straw transport chain cannot be removed, the clamping rod side is removed and the clamping rod side is attached again to perform threshing work. Therefore, the work of removing the clogged straw was very troublesome.

However, the present invention is directed to a straw transport comprising a clamping rod 12 for transporting threshed straw, and a straw transport chain 13 provided on the upper side thereof, outside the handling chamber where the handling cylinder 6 is fixed. A straw transporting device of a threshing device, comprising a device 11 and an upper cover 7 provided above the straw transporting device 11;
13 is configured to move up or down by an operation mechanism that operates in conjunction with the opening operation of the upper cover 7, and returns to the original position by an operation mechanism that operates in conjunction with the closing operation of the upper cover 7. Since the straw transporting device of the threshing device having the above configuration is used, only by opening the upper cover 7, the straw transporting chain 13 moves with respect to the pinching rod 12 to form a gap, and the jam is easily clogged. The waste straw can be removed, and when the upper cover 7 is closed, the straw transport chain 13 returns to the original position in conjunction with this operation, and the threshing operation can be performed.
