Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention is a storage chamber in which a screw type handling cylinder formed by winding a spiral with a handling tooth wound around a storage shaft is installed in a handling chamber. The present invention relates to a handling barrel in a total culm throw-in type thresher that supplies the entire amount of grain culms to a handling room and performs threshing treatment.

(B) Conventional technology As a conventional technology configuration for changing the working height of the handling teeth attached to the spiral in the all-cullet throwing type threshing machine as described above, for example, it is disclosed in Japanese Utility Model Publication No. 61-128940. Known to be.

However, in the structure disclosed in this publication, the gap between the handle tooth and the net is changed by changing the operating height of the handle tooth, and it becomes impossible to maintain a constant clearance, which is a problem such as unhandled. Occurs.

(C) Problems to be solved by the invention As described above, in the conventional technology, the gap between the tooth and the mesh is changed by changing the working height of the tooth, and it becomes impossible to maintain a constant clearance. Since problems such as leaving teeth occur, the present invention keeps this constant without changing the gap between the handle teeth and the net to prevent unhandled teeth, while changing the operating height of the handle teeth The present invention was devised for the purpose of providing an all-cule-type threshing machine that can be adapted to the difficulty level of grain shattering.

(D) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention stores a screw-type handle barrel in which a spiral having handle teeth is wound around the handle shaft in a handle chamber. In the whole culm throwing type thresher for threshing by supplying the whole amount of grain culms to the handling room, in the side part from the upper hand to the lower hand in the rotation direction of the spiral part for attaching the handling teeth, An arcuate adjustment plate whose outer peripheral edge is formed in substantially the same shape as the outer peripheral portion of the spiral is bent, and the upper hand of the arcuate adjustment plate is pivotally attached to the spiral and the lower hand is separated from the circumferential surface of the body. The arc-shaped adjusting plate is freely retracted from the outer peripheral portion of the spiral so that the operating height of the handle can be changed and adjusted.

(E) Action With this configuration, the grain culm supplied to the starting end side of the handling chamber is threshed while being fed toward the end side by the screw type handling barrel. When the grain culms supplied to the chamber are difficult to shed, the lowering of the arc-shaped adjusting plate is brought closer to the peripheral surface of the handle body and is retracted from the outer periphery of the spiral to adjust the working height of the handle teeth to a high level. is there.

Then, since the treating tooth has a high action strength, the threshing action becomes great and the threshing treatment can be performed without difficulty.

When the grain culm is easily shredded or in the case of crops such as soybeans where crushed grains are likely to occur, the arcuate regulating plate body should be moved away from the peripheral surface of the handling cylinder, contrary to the above. Adjust the working height of the handling tooth to a low level by protruding it from the spoiler.

As a result, the threshing action of the handling tooth on the grain culm is reduced and an appropriate threshing treatment is performed.

Then, in this case, the operating height of the handle tooth is adjusted to be high or low as described above, but by this, the gap between the handle tooth and the receiving net does not change and the unhandled portion does not occur.

The main part of the present invention will now be described with reference to FIGS. 1 to 3. In the screw type handling cylinder (4), the spiral (3) is spirally formed on the entire peripheral surface from the start end side to the end side. Wrapped around,
The base portion of the handle tooth (2) is integrally attached to one side surface of the spiral (3) with an appropriate gap and is configured to rotate in the arrow (a) direction.

Reference numeral (5) is an arc-shaped adjusting plate body, which has an outer peripheral edge (5a) having substantially the same shape as the outer peripheral portion of the spiral (3) and has a portion of the spiral (3) portion to which the handle tooth (2) is attached. Rotation direction (a) While turning the upper hand to the lower hand on the other side, the upper hand is pivotally attached to the spiral (3) by the pin (28) and this pin (28) is attached to the lower hand. An elongated hole (29) drawn as an axis is drilled, and a bolt (30) is passed through the elongated hole (29) and screwed into the spiral (3). The handle cylinder (4) is configured so as to be spaced apart from and close to the peripheral surface of the handle cylinder (4) so that it can be retracted from the outer peripheral portion of the spiral (3).

Therefore, tighten the arc-shaped adjusting plate (5) with the bolt (30),
As shown in the dotted line in FIG. 1 and FIG. 3 or FIG. 2 due to the relaxation, the spiral tooth (2) is recessed from the outer peripheral portion and the outer peripheral edge (5a) is made to substantially coincide with the operating height of the treating tooth (2) ( H) has the same height as the height itself protruding from the outer peripheral portion of the spiral (3), and, for example, as shown by the phantom line in FIG. 1, the arc-shaped adjusting plate (5) is attached to the outer peripheral portion of the spiral (3). When projected from above, the arcuate adjusting plate (5) is overlapped with the side surface of the handle tooth (2), and the working height (H) of the handle tooth (2) is adjusted to a low working height (h).

Furthermore, if the lower hand of the arcuate adjusting plate (5) is separated and completely overlaps the handle teeth (2), the working height (H) becomes zero.

Further, FIG. 4 shows another embodiment of the arcuate adjusting plate body (5), in which the outer peripheral edge (5a) is bent by the outer peripheral part of the spiral (3) to cover this part. Is done.

(G) Effect of the Invention As described in detail above, the present invention has a screw-type handle barrel, which is formed by winding a spiral with a handle tooth around the peripheral surface, in the handle chamber, and the handle chamber is mounted to the handle chamber. In the whole culm throwing type threshing machine that supplies the whole amount of grain culms to the threshing process, in the side portion from the upper hand to the lower hand in the rotation direction of the spiral part for attaching the handling tooth, the outer peripheral edge of the spiral is attached. An arc-shaped adjusting plate is formed so as to have a shape substantially the same as that of the outer peripheral portion, and the upper hand of the arc-shaped adjusting plate is pivotally attached to the spiral so that the lower hand can be moved away from and close to the handling cylinder peripheral surface. Since the body is projected and retracted from the outer periphery of the spiral to change and adjust the working height of the handling tooth, if the grain culms supplied to the handling room are difficult to shed, the arc-shaped adjustment plate is used as a lower hand. Shrink the granules by adjusting the working height of the treatment teeth by moving the teeth closer to the peripheral surface of the treatment cylinder and immersing them from the outer periphery of the spiral. If the crop is used too much and the grain culm is easily shattered or if crushed grains such as soybeans are prone to crushing, the arc-shaped adjusting plate should be used in reverse of the above to handle the lower side of the girdle. It is separated from the spiral and protruded from the spiral to adjust the action height of the treating tooth to a low level to reduce the shedding action, and it is possible to adapt to the difficulty of the shedding habit of various crops, so the range of application to crops is widened. Moreover, according to the present invention, the gap between the handle tooth and the receiving net does not change due to the adjustment of the working height of the handle tooth and is always constant, so that there is no problem such as unhandled tooth.
