かかっていた。According to the above-mentioned conventional construction, there is a problem that the handling cylinder cannot be manufactured without a special machine tool such as a roll machine. Further, in order to attach the teeth to the handle cylinder, the operator must screw the male threaded portion of the round bar and the nut into the cylindrical handle cylinder by inserting his / her hand through an opening at one end thereof. The operation had to be troublesome.

てある。The constitution, operation and effect of the invention according to claim 1 are as follows. (Structure) A plurality of crosspiece members are disposed in a state of being distributed around the handle cylinder axis in a posture along the handle cylinder axis, and the handle cylinder is provided via a support member provided at a plurality of locations in the handle cylinder axis direction. A handle cylinder is formed by being supported on a shaft, and a number of teeth are protruded from the beam member, and the beam member corresponds to a front beam member portion corresponding to the front half of the handle cylinder and a rear half portion of the handle cylinder. It is divided into a rear side bar member and is detachably attached to each of the support members.

特殊な工作機械がなくても製作することができる。[A] [A] The handling cylinder is provided with a plurality of crosspiece members at a plurality of positions in the handling cylinder axis direction in a state of being distributed around the handling cylinder axis in a posture along the handling cylinder axis. Since the handle cylinder is formed so as to be supported by the handle cylinder shaft via the provided support member, the handle cylinder can be manufactured without a special machine tool such as a roll machine.

合に比べて、作業を簡単に行うことができる。[B] Since the teeth are protruded from the bar member, the teeth are formed by, for example, a round bar material bent in a mountain shape, and both ends of the round bar member are formed on the bar member. When the nut is screwed from the back side of the cross member to the external thread formed at both ends of the round bar, or the base end of the toothing is In the case where the beam is fixed to the support member, the screwing operation of the male thread portion and the nut and the work of welding and fixing the proximal end of the toothing to the handle cylinder are performed before assembling the beam member to the support member. It can be performed using a large work space for each, and as in the past, the hands were inserted into the cylindrical handling cylinder from the opening at one end side, and the male threaded part on the round bar side and the nut were screwed together, etc. The operation can be performed easily as compared with the case of performing the operation.

When the worn teeth are to be replaced because they are attached, only the cross-bar portion of the front bar portion and the rear bar member that has the tooth that needs replacement, that is, generally the Since the teeth on the front half are more easily worn than the teeth on the rear half, it is possible to remove only the front cross member from the support member and replace the teeth. And
After replacing the toothing of the front side bar member portion, if the toothing on the rear half of the handling cylinder has become more worn than the toothing of the front side bar member portion, remove only the rear side bar member portion from the support member,
The toothing of the rear cross member can be replaced.

交換すればよい。For example, a toothing is formed by a round bar material bent in a chevron shape, and both ends of the round bar material are inserted into a pair of through holes formed in the front and rear beam members. When nuts are screwed into male threads formed at both ends of the bar from the back side of the bar member, after removing the toothing from the front and rear bar members, a new toothing is used. What is necessary is just to attach to the bar member part, and when the base end part of a tooth handling is welded and fixed to a handling cylinder, it is only necessary to replace the bar member part to which the tooth handling is welded and fixed with a new one.

The handling cylinder can be manufactured even in a factory having only a normal machine tool such as a drilling machine or a simple cutting machine, and the above operation (b) can reduce the labor of an operator required to attach the handling teeth to the handling cylinder. By the above operation (c),
When replacing worn teeth, it is not necessary to remove the entire bar member, and it is only necessary to remove the front or rear bar member portion from the support member, so that the workability of maintenance work can be improved. .

る。[E] At least one of the front side bar member portion and the rear side bar member portion is provided with two different tooth arrangement patterns.
Since it is composed of various types of cross-bar members and these are alternately attached to the support member in the circumferential direction of the handling cylinder, for example, as shown in FIG. 3, the structure is such that the handling teeth are arranged in a staggered manner on the handling cylinder. Thus, the shedding performance can be improved. And, in order to improve the particle-dropping performance in this way, it is only necessary to manufacture two types of crosspiece members having different tooth arrangement patterns. For example, various types of crossmember members having different tooth arrangement patterns are manufactured. Thus, the cross member can be manufactured at a lower cost as compared with a structure in which these are alternately attached to the support member in the circumferential direction of the handling cylinder.

すればよい。The beam member 4 is divided into a front beam member portion 4A and a rear beam member portion 4B, and is detachably attached to the first, second, and third support members 12A, 12B, and 12C, respectively. , When replacing the teeth 3 due to wear or the like,
Of the front side bar member portion 4A and the rear side bar member portion 4B,
Only the beam member portion having the tooth handling 3 requiring replacement, that is, generally, the tooth handling 3 on the front half of the handling cylinder is replaced by the tooth handling 3 on the rear half.
Since it is more susceptible to wear, only the front side bar member portion 4A needs to be removed from the first and second support members 12A and 12B and replaced with a front side bar member portion 4A having new teeth 3. This exchange can be performed in a short time because it is only necessary to release the pair of front and rear bolts 13 and then perform the fastening operation again. After the front bar member portion 4A is replaced, if the teeth 3 of the rear bar member portion 4B wear more than the teeth 3 of the front bar member portion 4A, only the rear bar member portion 4B is supported by the second and third supports. What is necessary is just to remove it from the members 12B and 12C and replace it with the rear side bar member portion 4B with the new toothing 3.

果的にささり籾を落とすことができる。As shown in FIG. 6, the pitch of the teeth 3 on the rear end side of the rear beam member 4B is set smaller than the pitch of the teeth 3 on the front end, The handle teeth 3 on the rear end side of the rear side bar member portion 4B located at every other position are inclined with respect to the rotation direction of the handling cylinder 2, and the remaining rear portion positioned between the rear side bar member portions 4B The toothed teeth 3 on the rear end side of the side beam member portion 4B may be inclined in the direction opposite to the rotation direction of the gripping cylinder 2. According to this structure, the waste straw is separated in the front-rear direction by the handling teeth 3 on the rear end side, so that the cut rice can be more effectively dropped.
