Abstract

PURPOSE:To prevent that an operator positioned at the front portion of a frame receives dust, by extending to near end portion of a screw auger forming a threshing cylinder to the outside of a threshing chamber and arranging an engine at the rear portion of the frame in a specific state. CONSTITUTION:The rear end portion of a screw auger 7 is extended outside a threshing chamber and straws, etc., are carried to the rear end portion of the screw auger and discharged outside the frame. The output shaft 21 of an engine 20 is disposed at the rear portion of the frame and the screw auger is directly driven with a belt. The cooling wind 22 for the engine is directed in the same direction as the directions of dust discharging and straw discharging.

Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention relates to a culm removal device for a screw type threshing machine, and more particularly to a culm removal device for a screw type threshing machine in which the handling barrel of the threshing section is constituted by a screw auger. [0002]

[Conventional technology]

By enlarging the diameter of the screw auger, which is originally used to convey grain in the axial direction, and giving it a predetermined rotational speed, and making the screw blades maintain the circumferential speed necessary for the crops, the effect of conveying the crops can be improved. In addition, it has a threshing function. In addition, if the screw auger's catch gutter is changed to a catch net of an appropriate size for the crops, the grains threshed in the handling chamber will leak downward from the catch net, and the stems and straw waste culm will flow in the axial direction. It now has a so-called sorting function that transports it to the outside of the machine and discharges it outside the machine. This is a screw type threshing machine. As shown in FIG. 3, the culm discharge section of the threshing section in a conventional screw-type thresher is equipped with auxiliary devices such as a beater 51 behind the screw auger 50, thereby removing stems and straw waste as shown by the broken line 52. The culm was being discharged outside the machine. [0003]

[Problem to be solved by the invention]

The conventional method described above not only requires an auxiliary device for ejecting the culm, but also wastes space in the handling room. Also, it is easier for the operator to catch the dust generated by auxiliary equipment such as beaters). SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a screw type threshing machine that does not require conventional auxiliary equipment and does not expose the operator to dust. [0004]

[Means to solve the problem]

In order to achieve the above objects, the present invention provides the following screw type threshing machine. That is, in a machine in which the handling body is formed of a screw auger, the rear end of the screw auger is extended outside the handling room, and the engine is arranged at the rear of the fuselage, and the direction of cooling air for the engine is directed from the exhaust culm of the screw auger. This is a screw-type threshing machine characterized by the fact that the direction is the same as that of the grain. [0005]

[Effect]

Not only can the culm be discharged using the screw auger itself that extends outside the handling room, but the exhaust culm and dust are blown to the rear of the machine by the cooling air from the engine located at the rear of the machine, so the operator does not receive dust, and the engine intake air is not exposed to dust. [0006]

【Example】

First, the entire screw type threshing machine will be explained with reference to FIG. Grain is raked in by a raking reel 1 and harvested by a cutting blade 2.
The harvested crops are moved from the raking auger 3 to the feeder house 4.
The grain is transported to a handling room 6 by a chain conveyor 5, and threshed by a handling drum 7 consisting of a screw auger. The threshed grains fall from the receiving net 8 onto the sorting auger 9,
The rotating auger 9 moves the direction toward its terminal end. During this conveyance process, grains and fine straw waste leak downward from the receiving net 9a stretched over the receiving gutter portion of the auger 9, and only the long straw is carried toward the dust exhaust port 10. Leakage including grains that have fallen from the receiving net 9a is conveyed onto the No. 1 gutter 13 by a belt conveyor 12, and the grains are transferred to the No. 1 gutter 13 and into the No. 2 gutter by being subjected to sorting air by a blower fan 11 such as a chisel. The object fell into the second gutter 14,
The grains that have fallen into the trough 13 are transferred to a paddy tank 17 by a grain-lifting conveyor 16, and the two spices are returned to a handling room 6 by a second return conveyor. Note that 15 is a crawler equipped with a threshing device. [0007] In the present invention, in the culm discharge part of the threshing part as described above, the rear end part 7a of the screw auger extends outside the handling chamber 6, and the length of the extension is one pitch or more. Therefore, the straw etc. threshed in the handling chamber 6 are discharged by the rear end 7a of the screw auger and discharged outside the machine as shown by arrow a. Also, since the screw auger requires a large amount of power, Fig. 2
As shown in the figure, the output shaft 21 of the engine 20 is arranged at the rear, and the screw auger 7 is directly driven by the belt 23. By setting the direction of the engine cooling air 22 in the same direction as the dust exhaust and the exhaust culm, the intake air of the operator and the engine is prevented from receiving dust. Further, since the engine 20 is located at the rear end of the machine body, the weight is balanced with the reaping section which is largely overbanked at the front of the machine body. [0008]

【Effect of the invention】

According to the present invention, the culm can be directly excavated by the screw auger itself extending outside the handling room, so there is no need for an auxiliary device such as a beater. Since the auger can be lengthened accordingly, the threshing ability is improved and long straw waste does not fall onto the swinging sorting board, improving the sorting performance. In addition, since the direction of the cooling air from the engine located at the rear of the aircraft is the same as the direction of the screw auger's exhaust culm, dust is discharged to the rear of the aircraft, and the operator located at the front of the aircraft is not exposed to dust and can easily access the engine intake air. Since the engine is located at the rear of the aircraft, it has the effect of balancing the weight with the large overhanging reaping section at the front of the aircraft.
