Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a spiral handle tooth for transferring an object to be processed is attached to the main part of the handle body in the axial direction thereof, and the spiral handle tooth is juxtaposed in the longitudinal direction of the screw so as to protrude from the outer peripheral edge of the screw. The present invention relates to an axial-flow type handling cylinder having handling teeth.

[0002]

[Prior Art]

 Conventionally, in the spiral handle of an axial flow type handle, the handle is provided at equal intervals over the entire length of the screw and at the same angle with respect to the radial direction of the handle body.

[0003]

[Problems to be solved by the device]

 However, if the number of handling teeth is increased, the threshing load increases when the water content of the processed material or the processed material is large, making it difficult or impossible to drive the handling cylinder. When the amount of dust such as cracks and broken straws increased, and conversely the number of handling teeth was reduced, the threshing performance deteriorated and it was difficult to properly set the number of handling teeth. An object of the present invention is to improve threshing performance, reduce threshing load, and reduce the amount of dust generated by improving the installation condition of the handle teeth.

[0004]

[Means for Solving the Problems]

 According to the characteristic configuration of the first invention, a spiral handle tooth for transferring an object to be processed is attached to a main part of the handle body, and the screw is protruded from the outer peripheral edge of the screw. In the axial flow type handling cylinder with the handling teeth arranged side by side in the longitudinal direction, the handling teeth in which the parallel spacing of the handling teeth in the specific range on the starting end side of the workpiece transfer of the main part of the handling cylinder body is in other ranges It is set to be smaller than the parallel spacing. Further, the characteristic configuration of the second invention is that a spiral handle tooth for transferring an object to be processed is attached to a main part of the handle body, and the screw is protruded from the outer peripheral edge of the screw to the spiral handle tooth. In an axial flow type handling cylinder equipped with teeth arranged side by side in the longitudinal direction, the clearance angle of the handling teeth in a specific range on the starting end side of the workpiece transfer of the main part of the handling cylinder body It is set to be smaller than the clearance angle of.

[0005]

[Action]

 When the actual state of the threshing action state by the axial flow type handling cylinder was confirmed experimentally, it was found that in the main part of the handling cylinder main body, a specific range on the starting end side of the workpiece transfer, for example, about 1/3 of the starting end side, It was found that most of the grain was shattered. Based on this fact, various investigations were carried out to find out what arrangement of the handle teeth is appropriate, and as shown in the characteristic configuration of the first invention, the side-by-side spacing of the handle teeth in the specific range on the starting end side is treated in other ranges. It has been found that if the distance is set smaller than the interval between teeth, the threshing performance can be easily improved, the threshing load can be reduced, and the generation of dust accompanying threshing can be suppressed. In other words, by increasing the number of handling teeth installed in the shredding range, it is possible to improve the threshing performance by increasing the frequency of operation of the handling teeth in the shattering treatment range, and to complete the most shredding. The treated items are given a relatively weak threshing action such that the handling teeth with a large interval between them act to reduce untreated residue and crust grains and grains attached to branch shoots, thereby reducing the threshing load and reducing the amount of dust generated. It has become possible to reduce the number.

Further, as in the characteristic configuration of the second aspect of the present invention, it is easy to set the clearance angle of the handle teeth in the specific range on the start end side to be smaller than the clearance angle of the handle teeth in other ranges. It was found that the threshing performance can be improved, the threshing load can be reduced, and the generation of dust associated with threshing can be suppressed. In other words, the threshing performance can be improved by reducing the clearance angle of the handling teeth in the range of threshing to enhance the crop capture function, and for most of the processed products that have undergone shattering, a handling tooth with a large clearance angle should be used. By applying a comparatively weak threshing action to the extent that it causes unremoved residue, clam grains and grains attached to branch shoots, it has become possible to reduce the threshing load and the amount of waste generated.

[0007]

[Effect of the device]

 As a result, it has become possible to provide a more excellent axial flow threshing device that can easily improve threshing performance, reduce threshing load, and reduce the amount of dust generated all at once.

Attached in a state of protruding from the outer peripheral edge and juxtaposed in the longitudinal direction of the screw, the grain culms are threshed by the action of the spiral handling teeth 6 as the handling body 5 is driven and rotated, and transferred to the rear. It is configured as follows. As shown in FIG. 2 and FIG. 3, the side-by-side spacing L ₁ of the handling teeth 6b in a specific range X of about 1/3 of the main body 5b of the handling body 5 on the starting material transfer start side is set to another range It is made smaller than the parallel spacing L ₂ of the handle teeth 6c in Y to make the threshing function of the specific range X where most of the grains are shattered high, and in other ranges Y, the threshing function is a little. It is designed to reduce the amount of threshing load and the amount of dust generated while reducing the amount of clam grains and grains attached to branch shoots by reducing the amount of untreated grain. Incidentally, the specific range X is provided with about 16 handle teeth 6b per turn, and the other range Y is provided with about 8 handle teeth 6c per turn.
