[Problem that the idea aims to solve]

In the conventional technology, the stirring plate in the working position is moved in the radial direction of the rotary cylinder by any of the above methods. It stands vertically or almost vertically along the line. However, in this case, the threshed In many cases, the resistance given to the This causes waste to be moved around the handling room more than necessary, making it easier for waste to get mixed in with the first process. There are disadvantages such as the rotation load being too large due to the stirring plate. It has become clear that The object of the present invention is to realize a threshing device with an agitation plate that does not have the above-mentioned disadvantages.

0004

[Means to solve the problem] For the above purpose, the present invention is based on the handling barrel structure of the axial flow type threshing device described at the beginning. This is a process in which the stirring plate is raised against the outer circumferential surface of the rotating cylinder to produce stirring action. In addition to being configured so that the posture can be changed freely between the posture and the non-working posture where stirring action does not occur, The threshing material that collides with the stirring plate in the working position and is thrown away spirals. The characteristic configuration is that the teeth are inclined toward the direction in which the threshing material is fed. do.

[0005]

[Effect]

In the characteristic configuration described above, it is attached to the stirring plate during the working posture and is detached from it by tilting. The impact when the processed grain collides, that is, the threshing load, is reduced. And with a stirring plate So that the threshed material that is splashed away is directed in the direction in which the threshed material is fed by the spiral handling teeth. As a result, the transfer action within the treatment room for processed materials is promoted, making it easier to discharge straw. At the same time, the flow of the processed material changes suddenly at the stirring plate part as in the conventional method. Damage or breakage of the processed material due to excessive impact of the stirring plate during threshing of difficult-to-thel grain materials such as rice. Inconvenient phenomena such as straw being carried around can be reduced. It also has good shedding properties for wheat, etc. When threshing potatoes, it is best to put the stirring plate in a non-working position. The setting of the inclination angle is Select as appropriate depending on the threshed product.

[0006]

[Effect of the idea]

Therefore, by simply modifying the stirring plate in the working position, While it is possible to improve threshing efficiency by promoting the discharge of waste, it also prevents grain damage and It is possible to improve problems such as the mixing of cut straw into the grain and the decrease in threshing efficiency due to overload. , we can provide a handling barrel structure for axial flow type threshing equipment that improves the performance and efficiency of the equipment. came.

【Example】

Embodiments of the present invention will be described below based on the drawings. Figure 1 shows an axial flow type threshing device A of a full-culm input type combine harvester, where B is a handling cylinder and C is a selection cylinder. It is a separate device. The handling cylinder B has a predetermined lead on the outer periphery of the rotating cylinder 4 attached to the drive shaft 1 facing forward and backward. Consisting of a large number of handling teeth 6 forming a single spiral body (corresponding to spiral handling teeth) 5 with corners. In addition, a wire rod 9 is provided in the frame 8 below the handling chamber 7 in which the handling cylinder B is housed. A cone cave 10 is arranged. The sorting device C includes a swing sorting mechanism 11, a winch 12, a No. 1 screw 13, and a No. 2 screw. The material collected by the No. 1 screw 13 is collected by a group (not shown). In the rental tank, the material collected by the No. 2 screw 14 is returned to the swinging sorting mechanism 11. It has become so. The single handling tooth 6 in the handling barrel B is configured to span a 90 degree range as a spiral body 5. The handling tooth 6 is formed by integrating the handling tooth portion and the flange portion by pressing. Ma In addition, it is installed across the handling teeth 6 that are adjacent to each other in the axial direction, and imparts an agitation action to grain threshing. Stirring plates 19 are provided at multiple locations.

[0008] Next, the stirring plate 19 will be explained. As shown in FIG. 2, the stirring plate 19 has a spiral structure 5 Brackets 20, 20 located between the pitches of and bolted to the front and rear handling teeth 6. An inclination angle α where the front side is closer to the upper side in the rotation direction when viewed from above with respect to the rotation axis P of the handling cylinder B It is pivotably supported around an axis X with A non-working position with the axis X located on the side and along the outer periphery of the rotary cylinder 4. It can be fixed freely with the mounting bolt 21 so that it can be used for threshing grains with good threshing properties such as wheat. The handling cylinder B will be in a state suitable for. Therefore, the stirring plate 19 can be handled after removing the mounting bolts 21 and putting it into a free swinging state. When the barrel B rotates, it swings around the axis X due to centrifugal force and moves along the radial direction of the rotating barrel 4. The machine becomes in an upright working position, and the handling cylinder B is in a state suitable for threshing difficult-to-thresh materials such as rice. However, due to the inclination angle of the axis X, the threshing process collides with the stirring plate 19 and is thrown away. The objects are now directed in the direction in which the helical body 5 feeds the threshed material. By providing a plurality of holes for pivoting the bracket 20, etc., when the stirring plate 19 is erected, It is convenient in practice if the inclination angle α can be selected and set as appropriate.
