Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus which performs a threshing action by applying a handling process to a treated grain stem conveyed by a feed chain using a handling cylinder.

[0002]

2. Description of the Related Art In the above-mentioned handling system, a feed chain sandwiches a stem portion of a processed grain stem and pulls a head portion.

[0003]

In this case, the tip portion of the spike is inevitably delayed, and the posture of the treated cereal culm becomes inclined from the posture required for the handling process, so that the sufficient handling process cannot be received. . In this way, the point where the tip side is likely to be delayed was determined by adopting a method of improving the delay of the tip side as much as possible by providing a marrow in the culm introduction part of the handling cylinder and combing the tip side into the handling room. However, it is not enough, and further improvement is required. An object of the present invention is to provide a threshing apparatus that eliminates delays at the tip side and that does not damage the grain culm by a mechanism that acts gently on the treated grain culm.

[0004]

Means for Solving the Problems [Structure] The characteristic structure of the present invention according to claim 1 is to move a grain stalk from a grain stalk insertion port of a handling room to guide a handled grain stalk conveyed by a feed chain. On the culm guide surface of the lower lip board provided along the direction,
A projection is formed to guide the handling grain from the conveying surface of the lower lip plate in a direction approaching the handling cylinder, and a grain facing the grain stem conveying direction on the upper side of the projection has a grain stem. The point is that the first inclined surface is provided such that the height of the protrusion becomes higher toward the lower side in the moving direction, and the operation and effect are as follows. [Operation] In other words, the presence of the projections can provide resistance to the stock root portion sandwiched on the threshing feed chain side and eliminate the stock root preceding state. it can. In addition, since the projection has the first inclined surface, the treated grain stalk moves along with the movement of the threshing feed chain, and when it comes into contact with the projection, the surface is the first inclined surface. The treated culm is gently lifted along its slope. [Effect] Therefore, the treated culm can be treated in an intended posture, and a sufficient shedding action can be performed in the handling room, and the cereal culm is damaged by the presence of the first inclined surface. Appropriate resistance can be given without receiving.

[Structure] According to a second aspect of the present invention, in the invention according to the first aspect, the height of the projection increases as the surface of the projection facing the feed chain moves away from the feed chain. It is formed on the second inclined surface, and its operation and effect are as follows. [Function and effect] Since the second inclined surface is provided, it can be extended almost straight into the handling room from the base of the stock held by the threshing feed chain to the tip of the spike, thereby forcing the handling grain pulp to an unreasonable posture. With the action of the two inclined surfaces, proper movement resistance can be given by the projections without damaging the grain stem.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A self-removing combine threshing apparatus A will be described. As shown in FIG. 1 and FIG. 2, while inserting the cereal stalk a sandwiched by the threshing feed chain 1 through the cereal stalk insertion port 3A of the handling room 3 provided with the handling drum 2 with the movement of the threshing feed chain 1, The cereal stem a is configured to give the handling function of the handling cylinder 2. A receiving net 4 is provided for allowing the grains separated from the cereal stem by the tooth handling 2A to leak downward, and a sorting unit B for rocking and sorting the grains, the paddy with branches, and the like leaked from the receiving net 4 is provided. It is provided below.

As shown in FIG. 2, a side opening 3B is provided on the side of the handling room 3 to allow the movement of the grain culm a sandwiched by the threshing feed chain 1, and the grain culm is directed downward from the side opening 3B. An inclined lower lip plate 5 for guiding the cereal stem a that moves together with the threshing feed chain 1 while guiding the tip side of a to the receiving net 4 is provided.

[0008] The implanting structure of the tooth handling 2A will be described. As shown in FIG. 1, a handling tooth 2A is planted in the handling cylinder 2, and the handling tooth 2A is provided at a grain stalk introduction inlet portion of a grain stalk insertion opening 3A of the handling cylinder 2 and is provided with a feed chain 1A. A straightener 2a acting to pull the tip of the transported grain culm for threshing sandwiched in the handling chamber into the handling room, a reinforcing tooth 2b planted at an intermediate position in the handling cylinder axial direction, and a rear end portion Provided parallel teeth 2c
And it is comprised. The toothing 2A is a wire tooth type in which one bar is bent and both ends are implanted in the gripping cylinder 2. In the case of the straightening element 2a, the height of the teeth is relatively low and the legs at both ends are implanted in the gripping cylinder 2. The width is wide, and the height of the teeth is slightly increased and the leg width is reduced in the case of the reinforcing teeth, and the height of the teeth is further increased and the width of the legs is further reduced in the case of the parallel teeth.

The projection 6 provided on the transport surface of the lower lip plate 5 will be described. As shown in FIGS. 2 to 5, at a position corresponding to the above-described reinforcing teeth 2 b, a single protruding piece is projected on the inclined conveying surface of the lower lip plate 5 so as to guide the treated culm in a direction approaching the handling cylinder 2. One protrusion 6 is provided. This projection 6 is shown in FIGS.
As shown in FIG. 5, a surface (first inclined surface) 6A facing the threshing feed chain 1 (second inclined surface) 6B and a surface (first inclined surface) 6A on the upstream side in the transport direction toward the grain culm introduction port are inclined surfaces. In addition, gentle movement resistance is given to the treated culm. That is, the inclined surface 6A on the upper side in the transport direction is
It is configured such that the lower side in the transport direction is closer to the handling drum 2, and when the root portion of the handling grain culm that is nipped and transported by the threshing feed chain 1 comes into contact with the inclined surface 6A,
With the movement of the threshing feed chain 1, the treated grain culm is raised along the inclined surface 6A. As a result, a movement resistance acts on the treated cereal stem by the projections 6, thereby preventing the root portion of the treated cereal stem from tending to precede the head portion. In other words, as described above, the aligner 2a is provided at the front end of the handling cylinder 2, and the aligner 2a is introduced into the handling chamber so as to fry the tip from the middle stem portion of the treated grain culm. I do. Thereby, the handling grain culm becomes a posture in which the stock side and the tip side are orthogonal to the handling cylinder axis direction, and can be handled comfortably. However, the soshiko 2a
If the introduction of cereal stalks in the cultivation did not work well, the stock side tends to precede.
Thus, the sliding resistance is given, and the delay of the tip portion can be recovered. Since the surface of the projection 6 that comes into contact with the base is an inclined surface, gentle resistance can be given, and damage to the base of the base can be avoided.

As shown in FIG. 7, an inclined surface 6B is also provided on the surface of the projection 6 toward the threshing feed chain 1, and this is provided between the threshing feed chain 1 and the handling cylinder 2 and the receiving net 3. The stem portion where the treated grain stalk a that has penetrated into contact with the projection 6 does not bend.

[Another embodiment] A. In the above-described embodiment, the two inclined surfaces 6A and 6B are provided as the inclined surfaces of the protrusion 6, but it is sufficient that at least the surface 6A facing the upper side in the transport direction is the inclined surface. B. The projection 6 may be formed by bending a leaf spring or the like in a curved manner. This can also provide moderate resistance.
