Description

[Detailed description of the invention] In this invention, the base of the scraping rod is pivotally attached to the inner eccentric shaft of the cylindrical body, the other end is inserted through a hole drilled on the outer periphery, and the cylindrical body is rotated. This invention relates to a scraping roll that has the effect of scraping shell culms, etc. with a scraping rod.

When the cylindrical body of the raking roll is long or when the raking rod is installed biased toward one end of the cylindrical body, it becomes particularly difficult to pivot the raking rod to the eccentric shaft inside the cylindrical body. .

This invention is constructed as follows in order to solve the difficulty of assembling the scraping roll.

That is, a cylindrical body 40 having a recessed hole 1 on its outer periphery through which the scraping rod 3 is inserted is equipped with a flange 6 on one end that supports a fixed shaft 7 having an eccentric shaft 2 to which the scraping rod 3 is pivotally attached. At the same time, a drive shaft 18 for rotating the cylinder 4 is provided at the other end of the cylinder 4.
This is a configuration of a roll for scraping in a shell culm, etc., which is equipped with an extension cylinder 5 having a cylindrical extension body 5.

This invention has the following technical effects by configuring it in this way.

That is, a fixed shaft 7 that pivotally supports a flange 6 attached to one end of the cylinder 4, and an extension cylinder 5 attached to the other end of the cylinder 4.
Since both ends of the scraping roll are supported by the drive shaft 18 of the scraping roll, it can be supported reliably, and the structure is simpler than a structure in which an eccentric shaft is fixed to one end of the scraping roll and the cylinder is rotated. be.

In addition, since the extension cylinder 5 having the drive shaft 18 is attached to the cylinder 4 that houses the eccentric shaft 2, by separating the extension cylinder 5 from the cylinder 4, the eccentric shaft can be removed from the separated end. 2 can be easily attached to the base of the rake rod 3.

To explain the embodiment with reference to the drawings, the scraping roll is composed of an extension cylinder 5, a cylinder 4, and a flange 6, each of which is integrally formed by providing fitting unevenness on the corresponding end surface so that the center of rotation coincides with the other. It is possible to assemble the

A pair of recessed holes 1 are provided on the outer peripheral surface of the cylinder 4 symmetrically with respect to the center of rotation, and openings 25 and 26 of appropriate diameters are provided in the left and right side walls 23 and 24, and +i, fixed and fixed holes are provided in the cylinder. The base portions 9 of a pair of raking rods 3 are pivotally supported to the bent pongee 2 fixed by a shaft arm 8, and the tips of the raking rods 3 are slidably inserted through the recessed holes 1.

The fixed shaft I has a flange 19 on its end surface and is fixed to a side wall 20 with bolts 21.

The base 9 of the rake rod 3 is inserted into the eccentric shaft 2, pushed in the axial direction by a spring 10, and prevented from being pulled out by a nut 11 to provide appropriate rotational resistance.

A bearing 12 is fitted into the center of the flange 6, and a fixed shaft 7 is inserted through the bearing so that the flange 6 can rotate relative to the flange 6 and is fixed to the cylindrical body 4 with bolts 13.

The flange 6 can be moved to a position where the entire arm 8 faces the opening 26 by removing the bolt 13 while the eccentric shaft 2 is fitted into the cylinder 4.

Further, the arm body 8 and the eccentric shaft 2 are set in a relationship such that they can be inserted into and removed from the opening 26.

One side outer periphery of the extension cylinder 5 is formed into a recess into which the convex part of the cylinder 4 is fitted, and is fixed with a port 14 that is inserted integrally with the cylinder 4 through the hole 27.

A boss portion 15 having a square fitting hole in the center is provided on the other side of the extension cylinder 5, and a square shaft portion 22 of a drive shaft 18 rotatably pivoted to the side wall 16 by a bearing 17 is fitted into the boss portion 15. Fits into the hole.

When the drive shaft 18 is rotated, the scraping roll consisting of the cylindrical body 4, flange 6, and extension cylindrical body 5 rotates, and the side wall 2
The rake rod 3 has a base 9 pivoted on an eccentric shaft 2 fixed at 0.
It rotates around this eccentric shaft 2 while being pushed by the outer circumferential wall of the cylinder 4, and protrudes and retracts from the outer circumferential surface of the cylinder 4.

By making the free end side of the eccentric shaft 2 of the cylinder 4 openable in this manner, the bases 9 of the pair of scraping rods 3 are inserted into the eccentric shaft 2 through this opening, and the bases 9 are held together by the spring 10. Complicated assembly such as pressing can be easily performed.
