Description

[Detailed explanation of the invention] (a) Industrial application field The present invention has a handling chamber and a wind sorting section arranged above and below on a traveling vehicle, and a reaping section in front of the vehicle. This invention relates to a threshing device in a reaping threshing machine that supplies the entire amount of grain into a handling chamber for threshing.

(b) Prior Art Conventionally, a reaping and threshing machine and its threshing device for supplying the entire amount of harvested grain culm into a handling chamber for threshing processing have been disclosed, for example, in Japanese Utility Model Application No. 4122/1983 or Japanese Utility Model Application No. 58/1983.
It has been published in Publication No. 137029, etc.

However, as in the above-mentioned Japanese Unexamined Utility Model Publication No. 137029/1980, the handling teeth are independently implanted between the pitches of the spiral body wound around the peripheral surface of the handling cylinder.

Therefore, the straw culms were caught in the independent handling teeth and stagnated regardless of the conveying action of the wound spiral body, resulting in a clogging phenomenon in the handling chamber.

(c) Problems to be solved by the invention In view of the above-mentioned actual situation, the present invention prevents the straw culm from being caught and wrapped around the handling teeth, completely eliminates the phenomenon of clogging in the handling chamber, and improves the handling barrel and receiving net. It was provided for the purpose of efficiently performing the threshing process by eliminating the increase in load on the machine, eliminating wasted power, and uniformly distributing grain culms within the handling room and improving processing capacity. It is something.

(d) Means for solving the problem Therefore, in order to achieve the above-mentioned object, the present invention provides a handling chamber and a wind selection section above and below on a traveling vehicle, and a reaping section is provided in the front. In a reaping and threshing machine that feeds the entire amount of grain harvested into a handling chamber for threshing, the grain culm is transferred from the grain culm supply port side to the straw culm discharge side on the circumference of the handling barrel, which is stored on a shaft in the handling chamber. A spiral body is wound so that the outer peripheral edge of the spiral body has an appropriate distance from the receiving net, and the non-transfer working surface on the back side of the transport working surface of the spiral body is made to protrude from the outer peripheral edge and have a receding angle. The rod-shaped handling teeth were closely fixed on the base side and evenly spaced.

(E) Effect With this structure, the entire amount of grain culm harvested in the reaping section is supplied into the handling chamber from the grain culm supply port, and is forcibly transferred toward the straw culm discharge side by the spiral body. The outer edge works together with the receiving net to rub the grain culm and thresh it.

In this case, the rod-shaped handling teeth not only have a threshing effect, but also catch and disperse the grain culms that are being transferred in a group by the spiral body, and homogenize the grain culms in the process of being transferred within the handling chamber. The grain culm is pressed against the receiving net side by the receding angle and rubbed, and the threshing process is performed efficiently.

A dust suction port 8b is provided on the rear side of the suction and dust removal chamber 8, that is, the side wall 8a opposite to the handling chamber B, and an annular hole that fits into the notch 9a of the suction and dust removal impeller 9 is provided on the inner peripheral wall 8c. A partition wall 10 is erected to divide the inside of the suction and dust removal chamber 8 into a handling chamber B side and a dust suction port 8b side.

The above-mentioned handling barrel 7 has a line extending from the grain culm supply port B' side to the straw culm discharge side X over the entire circumference from the front part to the rear part.
A spiral body 11 for transporting the grain culms is wound around the spiral body 11, and its outer peripheral edge 11a is kept at an appropriate distance from the receiving net 12.

Reference numeral 13 denotes a rod-shaped handling tooth, the tip of which is located at the outer peripheral edge 11 on the non-transfer acting surface on the back side of the transfer acting surface of the spiral body 11.
The base side is fixed and equally spaced, protruding about 10 to 12 mm from A, and the tip rotates slightly behind the rotation direction shown by arrow A in Figure 2. The receding angle α is set so that

A vertical wall 14 is suspended in the front-rear direction below the relatively large mesh receiving net 12 forming the handling chamber B to form two processing chambers D and D' below the handling chamber B,
The bottoms of each of the processing chambers D and D' are configured in the form of a gutter with meshes 15 and 15a through which the grains pass, and screw conveyors 16 and 16a that transport the grains from the front to the rear are built into the gutter. A wind selection section C is provided below the processing chambers D and D'.

The front part of the wind selection section C is equipped with a pressure winch 17.
The sorting air generated by the pressurized air winnower 17 flows in the front-rear direction, that is, in the same direction as the handling barrel shaft 7a, bypassing the rear side of the blower processing chambers D and D' and communicating with the dust suction port 8b through a sorting air path. 18, and the screw conveyor 16, 16a

In addition, 20 is a first item removal gutter, and 21 is a second item removal gutter.

Therefore, when the machine is moved forward, the standing grain culms are placed in a backward position by the rotary reel 1, and the culm base is harvested by the cutting blade 2, and those on the right side are transferred to the left by the spiral of the guide 3, and are harvested on the left side. It joins up with the other feeders and is fed into the feeder house 4 by the scooping rod 8a.

The fed grain culm is sent to the front part of the handling chamber B from the grain culm supply port B' by the grain culm transporting body 5 which rotates in the direction shown by arrow B, and is conveyed by the transfer action surface of the spiral body 11. The straw is forcibly transferred backward, that is, toward the straw culm discharge side X, and the outer peripheral edge 11a cooperates with the receiving net 12 to rub the grain culm and perform a threshing action.

In this case, the protruding rod-shaped handling teeth 13 whose base portions are closely fixed to the non-transporting surface of the spiral body 11 not only have a threshing action but also handle grain culms that are to be transported as a group by the spiral body 11. Grain culms that are hooked and dispersed and are being transported are made uniform in the handling chamber B, and the grain culms are pressed against the receiving net 12 side by the receding angle α to perform the threshing process efficiently. The grains of the culm are removed and discharged from the handling chamber B side of the suction and dust removal chamber 8.

In addition, unprocessed materials such as grains and ear cuts, and dust such as straw waste pass through the receiving net 12 with a relatively large mesh and fall into the respective processing chambers D and D'.

The fallen grains, etc. are transferred to each processing chamber D, D' by screw conveyors 16, 16a to form a mesh 1.
5, the bottom of 15a is directed backward to receive the transfer action,
Grain and fine dust leak through the meshes 15, 15a, unprocessed items such as ears of ears are shredded, and straw waste is transferred to the rear by whirlwind blades 19, 19a rotating in the direction of arrow C.
It is jumped up in a state of merging in the center by.

The grains and fine dust leaking from the meshes 15 and 15a are sorted by the sorting air that is blown through the sorting air passage 18 by the pressure winch 17 and the suction dust removal impeller 9. The second articles are taken out of the machine from the article take-out gutter 20 and the second article take-out gutter 21, and the fine dust is sent through the sorting air passage 18.

On the way, the fine dust is transferred to the whirlwind blade 1.
9 and 19a further enhance the feeding action, and the straw dust thrown up by the whirlwind blades 19 and 19a is sucked into the dust suction port 8b side of the suction dust removal chamber 8 and discharged outside. It eventually joins the straw culms discharged from the handling room B side and is discharged outside the machine.

(g) Effects of the invention As detailed above, the present invention has a handling chamber and a wind sorting section arranged above and below on a traveling vehicle, a reaping section in the front, and a total amount of grain culm harvested by the reaping section. In a reaping and threshing machine that supplies straw into a handling chamber for threshing, a spiral body for transferring the straw from the grain culm supply port side to the straw culm discharge side is attached to the outer periphery of the helical body on the circumferential surface of the handling barrel that is stored in the handling chamber. is wound with an appropriate spacing from the receiving net, and on the non-transporting surface of the helical body on the back side of the transporting surface, rod-shaped handling teeth projecting from the outer periphery and having a receding angle are attached to the base thereof. Since the sides are tightly fixed and evenly distributed, the entire amount of grain that is harvested in the reaping section and supplied into the handling chamber from the grain supply port is transferred to the straw culm discharge side by the spiral body. The outer peripheral edge works with the receiving net to scrape and thresh the grain culms while being forcibly transferred toward the direction of the grain. Since the base side is tightly fixed and protruding,
The feeding action of the straw culm by the transfer surface is smooth, and the straw culm does not get caught at the base of the rod-shaped handling teeth, preventing the straw from being wrapped around the rod-shaped handling teeth, thereby preventing clogging in the handling chamber.

In addition, the rod-shaped handling teeth, at the same time as the threshing action, catch and disperse the grain culms that are being transferred as a group by the spiral body, homogenize the grain culms in the process of being transferred within the handling chamber, and retract the grain culms. Since the horns press against the receiving net side for rubbing, the threshing capacity is improved and the process can be carried out more efficiently.
