A straw removal belt covered with a belt cover 23 is extended toward the outside of the straw removal side, and an opening 25 is formed at the lower front side of the inlet side plate 24 which is the lower side of the supply port 20. An input pulley 26 and an output pulley 27 are installed coaxially on the outer side of the 24 in the longitudinal direction, and a transmission belt 28 that wraps around the output pulley 27 is installed to transmit power to each part. A shell cylinder 1 is extended from the No. 1 thrower 1a connected to the lower part of the straw side and inclined toward the front and rear of the machine, and the inside of the front side of the threshing machine A is formed as a space, and the above-mentioned supply A frame 29 is installed on the plate 21 so as to be able to be connected thereto.

An engine E is mounted on the frame 14 close to the front part of the threshing machine A, which is below the clamping rod 18, and an engine cover 30 is attached to the engine E, so that the grain culm of the threshing machine A is supplied. An opening/closing plate 32 with a net 31 stretched thereon is removably attached to the side of the engine cover 30 which is the rear side of the engine via each screw 33, and the side of the engine E which is the side facing the opening/closing plate 32 The control unit 10 is equipped with various adjustment parts 10 such as levers and governors, a muffler 34, an air cleaner 11, and the like.

A gear case 8 that protrudes into the lower front side of the threshing machine A is directly connected to the front side of the engine E, and a transmission shaft 35 that is directly connected to the crankshaft of the engine E and extends in the longitudinal direction of the machine body is connected to the gear case 8. A reduction gear 6, which is a bevel gear, is fitted to the tip of the shaft, and a PTO shaft 9, which is integrated with a reduction gear 7 in the form of a bevel gear that meshes with the reduction gear 6, is extended laterally to the gear case 8. The opening 28
Both pulleys 36 and 3 are attached to the PTO shaft 9, which is viewed from above.
7 is fitted, and a transmission pulley 38 is mounted on the inner side of the inlet side plate 24 and is pivoted on the side of the transmission case 12.
A belt 39 is placed around the pulley 36, and a belt 40 is placed around the pulley 26 and the pulley 37 on the outside of the entrance side plate 24, and both belts 39, 4
0 each has a tension clutch pulley 4
Tension clutch pulleys 41 and 42 are installed so that they can be operated by means of a clutch lever 43 that abuts the tension clutch pulleys 1 and 42 and protrudes toward the rear side of the engine cover 30, respectively.

At the rear of the threshing machine A, the engine cover 30
An operation box C is installed at the rear upper part of the threshing machine A at approximately the same height as the threshing machine A. The inside of the operation box C is divided into two chambers by a partition plate 44, and on one side there are the levers 3a and rear protrusions. A control device 3 consisting of a handle rod 3b is installed, and on the other side, a paddy tank 2 is installed, with which the tip of the shell lifting cylinder 1 communicates, and the paddy tank 2
A main paddy outlet 45 and an overflow paddy outlet 46 are provided vertically at the lower part of the main paddy outlet 45 .

In addition, the upper part of the bent support rod 47 is fitted into both protrusions protruding from the lower front surface of the operation box C, and both ends 47a, 47a of the support rod 47 are connected to the threshing machine A below the clamping rod 18. The operation box C is fixedly installed at the front and is installed to support the operation box C. As shown in FIG. The connecting rod 5 is installed so as to be biased toward the rear of the straw removal side of the machine A, and the tip of the connecting rod 5 formed in a U-shape in plan is aligned with the top surface of the operation box C and fixed with each screw 48. Both ends 5a, 5a of the chain cover 22 which forms the front part of the machine on the side of the feed chain 4
It is configured by fixing with each screw 48 according to the top.

From the upper part of the support rod 47 are both outlets 45 and 46.
Paddy receiving rods 4 located on both sides of the paddy bag and suspending the paddy bag
9, 49 are extended, and the frame 1 is installed below it.
It is constructed by erecting a paddy holder 50 that is supported from the 4th side.

Therefore, the engine E sucks air from the air cleaner 11 installed on the grain culm supply side of the threshing machine A, and when it is started, air is passed through the gear case 8 and decelerated, and is then transferred from the PTO shaft 9 to the threshing machine A via the belt 40. , and transmission case 1 from belt 39
2 to the traveling devices B and B, and each clutch can be selectively engaged by operating the clutch lever 43. When moving, an operator at the rear of the aircraft can move the vehicle in the approximate width direction of the aircraft. This means that the vehicle can be driven by operating the control position 3 at the central position.

The engine E has a power transmission structure directly connected to a gear case 8 that enters the lower part of the threshing machine A.
By opening the opening/closing plate 32 on the lateral side, the lateral side of the engine E can be opened, and each adjustment can be made without any obstructions from the lateral side of the engine E. This means that adjustments can be made to the parts 10, air cleaner 11, etc.

During work, attach the pedestal 29 to the supply plate 21,
A paddy bag is inserted through both paddy receiving rods 49 and suspended.
The operator will stand at position A, which is near the starting end of the feed chain 4, and feed the grain stems on the pedestal 29, but the end side of the operation box C, which is located at a high position, will be placed at the center O, and the operator will be placed on the supply side. Therefore, the operator can work without any obstacles, and can immediately operate the control device 3 and clutch lever 43 from the A position.

The operation box C is connected to the threshing machine A by means of a connecting rod 5.
Since it is supported from the sides, it has a sturdy structure even when maneuvering or receiving and unloading paddy.

As described above, the present invention provides a self-propelled self-threshing system in which a threshing machine is mounted above a traveling device and an engine is mounted on the rear side of the threshing machine. At the same time, a gear case is directly connected to the front side of the engine, and the gear case is inserted into the lower part of the threshing machine, and the threshing machine and the threshing case are connected through a PTO shaft installed laterally from inside the gear case. The power is transmitted to the traveling device through the respective engines, and each adjustment section and air cleaner of the engine are arranged on the grain culm supply side of the threshing machine. You can easily adjust each adjustment section, air cleaner, etc. without any obstructions, and since each adjustment section and air cleaner are located on the grain culm supply side, there is no straw waste generated during threshing. Since the gear case inserted into the lower part of the thresher is directly connected to the front side of the engine, it is possible to transmit power with high conduction efficiency, and this transmission structure allows the longitudinal length of the entire machine to be shortened, making it possible to reduce the overall length of the machine. It has the advantage that it can be downsized, has a simple structure, and can be suitably implemented.
