Description

[Detailed Description of the Invention] This invention relates to an improvement of a raking roll that rakes in the husk of rice or the like with a raking rod that emerges and retracts from a hole drilled in the outer periphery of the cylindrical body as the cylindrical body rotates.

The hole in which the scraping rod of the scraping roll enters and retracts is worn and enlarged by the reciprocating sliding of the scraping rod, which may cause the scraping rod to lose its function of scraping the culm.

This invention is intended to eliminate such inconveniences and is constructed as follows.

That is, a scraping rod hole 6 is bored in the rotating cylinder 2 through which the scraping rod 4 pivotally attached to the eccentric shaft 3 of the inner cavity of the rotating cylinder 2 is inserted, and a 5-surface area around the scraping rod hole 6 is formed on the outer periphery. A recess 31 of an appropriate depth is formed in the recess 31, and a cylindrical receiver 1 whose axial direction is substantially orthogonal to the axial direction of the scraping rod 4 is placed in the recess 31, and the outer part of the receiver 1 is connected to the rotary cylinder 2. The structure of the scraping roll such as a shell culm is provided so as to be able to be fitted and removed without protruding from the outer periphery of the 5 surfaces.

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

In other words, the raking rod 4 does not come into sliding contact with the raking rod hole 6, but slides with the removable receptacle 1 provided around the raking rod hole 6. It will wear out due to sliding contact.
If the receiver 1 wears out, it can be removed and replaced to replace the raking rod 4.
functions are retained.

Moreover, this replacement work can be easily performed from outside the rotary cylinder 2.

In addition, by fitting the receiver 1 into the recess 31 provided on the outer periphery 5 of the rotary cylinder 2 with the outer part of the receiver 1 not protruding from the outer periphery 5 of the rotary cylinder 2, the receiver 1 is inserted into the outer circumference 5 of the rotary cylinder 2. The shell culm protruding from the outer periphery 5 will not become entangled, and will not be displaced by the force in the rotational direction of the rotary cylinder 2 generated when the scraping rod 4 scrapes the shell culm.

Furthermore, since the receiving body 1 is formed into a cylindrical shape whose axial direction is substantially perpendicular to the axial direction of the scraping rod 4, the contact area between the scraping rod 4 and the receiving body 1 is small, so there is little sliding resistance, and scratching is possible. The appearance of the insertion rod 4 becomes light and smooth.

When explaining the embodiment based on the drawings, the scraping roll 2 is as follows:
It is composed of a vertical cylindrical body 7, a cylindrical body 8, and a flange 9, and can be assembled by providing fitting irregularities on the corresponding outer peripheral end faces of each body so that the centers of rotation coincide.

A boss portion 1 is provided at one end of the extension cylinder 7 and has a fitting hole into which a square shaft portion of a drive shaft 13 supported by a bearing 12 on a side plate 10 is inserted.
4, and the other end is provided with an outer peripheral portion 15 that fits into the cylindrical body 8 and a bolt hole 16 for assembly.

One end of the cylindrical body 8 is provided with an outer periphery convex part 17 for fitting the extension cylindrical body 7 and a screw hole 18 for assembly, and the other end is provided with an outer periphery convex part for fitting with the flange 9 and a screw hole 20 for assembly. and

A pair of raking rod holes 6 into which the raking rod 4 enters and retracts are provided in the outer circumferential surface 5 of the cylinder 8 symmetrically with respect to the center of rotation.
A recess 31 is formed around the recess 31, and the receiver 1, which comes into sliding contact with the rake rod 4, is removably fitted into the recess 31 with a bolt 21.

The flange 9 is provided with four outer circumferential parts 22 into which the cylinder 8 is fitted, and a boss part 25 in which a fixed shaft 23 fixed to the side plate 11 is pivotally supported by a bearing 24.

The eccentric shaft 3 is fixed to the fixed shaft 23 via the legs 26, and the base of the raking rod 4 is inserted into the eccentric shaft 3, pushed in the axial direction by the spring 27, and tightened with the nut 28. Adds rotation resistance.

The raking rod 4 pivotally connected to the eccentric shaft 3 is fitted into the cylindrical body 8 so as to be freely retractable into the raking rod hole 6, and the extension cylindrical body 7,
The cylindrical body 8 and flange 9 are integrally assembled with bolts 29° and 30°.

When the drive shaft 13 is rotated, the scraping roll 2 rotates, and the scraping rod 4 rotates around the eccentric shaft 3 while being pushed by the receiver 1, and moves in and out of the peripheral surface of the scraping roll.

When this scraping roll 2 is used, the scraping rod 4 and the receiver 1 come into contact with each other violently and wear out, so the receptor 1 is worn out and the scraping rod hole 6
However, by removing the bolt 21 and replacing the receiver 1, it is possible to return to the original fitted state of the raking rod hole 6.

In this way, by providing the receiver 1 in a removable manner so that the raking rod 4 can slide into and out of the periphery of the raking rod hole 6, parts that wear out quickly can be replaced and the raking rod 4 can be removed easily. The service life of the roll 2 is extended.
