Description

[Detailed description of the invention] The present invention involves introducing rice husks, etc. into a crushing barrel with the axial direction as the transverse direction from one end side of the crushing barrel, and then using feed blades provided in the crushing barrel to transport rice husks, etc. This invention relates to an improvement in a crusher for crushing rice husks, etc., which crushes rice husks by forcefully pushing it toward the other end and rotating it under pressure.

As shown in FIG. 1, the rice husk crusher of the above-mentioned configuration has a cylindrical peripheral wall 10,
The supporting leg 1 is in a position where its axial direction is along the horizontal direction.
1, the openings at both front and rear ends of the trunk peripheral wall 10 are closed by end walls 12 and 13 to form the crushing cylinder 1, and the crushing cylinder 1 has a front end side (the first An intake port 1a is formed on the upper surface (left end side in the figure), and a discharge port 1b is provided on one side of the rear end side of the trunk wall 10, and the discharge port 1b is closed with a pressure cover 14. A rotating shaft 2 is provided inside the crushing barrel 1 so as to pass through it in the front and rear directions, and its front and rear shaft ends are mounted on bearing support members provided on the front and rear end walls 12 and 13, so that the rotation thereof can be controlled. Straight plate-shaped feed blades 3 are attached to the shaft 2 in a radial manner when viewed from the axial direction, aligned in the axial direction. Torso 1
It is tilted with respect to the rotational direction so that rice husks, etc. to be thrown into the crushing cylinder 1 are sent out toward the rear end side of the crushing cylinder 1,
In addition, crushing rods 4...
are fixedly attached, and thereby rice husks, etc. input from the receiving port 1a are transferred to the rear end of the inner cavity of the crushing barrel 1 by the feed blades 3, which are rotated by the drive rotation of the rotary shaft 2. The rice husks, etc., are packed in the crushing rod and are compressed tightly, and are formed into a cylinder shape that follows the inner cavity of the crushing barrel 1 and rotated. By making
It is designed to be crushed.

The rice husk etc. crusher configured in this manner strongly pushes the rice husk etc. introduced into the crushing barrel 1 toward the end wall 13 at one end of the crushing barrel 1. During the work, the materials to be crushed, such as crushed rice husks, gradually solidify on the inner wall surface of the rear end of the crushing barrel 1, obstructing the rotation of the feeder blades 3, and reducing the crushing efficiency. Not only that, but the material to be crushed becomes firmly packed in the rear end side of the inner cavity of the crushing shell 1, which makes it impossible for the feed blades 3 to rotate and causes the rotary shaft 2 to stop rotating. Become. In such a case, conventionally, the direction of drive rotation of the rotary shaft 2 is reversed, and the packed material to be crushed is moved to the front end side of the crushing shell 1 by the feed blades 3 whose feeding direction is reversed. I try to deal with it by pointing it back at them.

By the way, the rice husk crusher of the above-mentioned form connects the PTO shaft S provided on the tractor T to its input shaft 2a via the coupling ring 5, as shown in FIG. In some cases, the machine may be activated to perform crushing work. When operating in this way, the tractor T
Since the PTO shaft rotates only in one direction and does not reverse, when the object to be crushed becomes clogged, the rotation shaft 2
By rotating the blades in the opposite direction, it is not possible to return the clogged material to be crushed to the receiving port 1a side by the rotating sending blades 3 and release the clog. For this reason, when a blockage occurs, the inside of the crushing drum 1 is opened to the outside and the material to be crushed that is clogged inside is scraped out manually. When axially mounting the crushing cylinder in the crushing cylinder 1, the end wall 13 on the rear end side of the crushing cylinder 1 is welded to the cylinder peripheral wall 10, and the end wall 1
The bearing support part 15 is removably assembled on the outer surface of the rotary shaft 2, and the front end wall 12 of the rotary shaft 2 on the side where the input shaft 2a is installed is removed. The crushing cylinder is inserted from the front end side of the crushing cylinder 1, and the bearing support part 15 is attached and pivotally supported at the point where the shaft end of the rear end protrudes from the end wall 12 on the rear end side. In order to open the inside of the rotary shaft 2 to the outside, it is necessary to twist and pull out the rotary shaft 2 along with the feed blades 3 in the reverse process of the assembly work of the rotary shaft 2. This makes the cancellation process extremely troublesome.

The present invention was developed to solve this problem, and when operating a rice husk crusher by connecting the PTO shaft of a tractor to its input shaft, the present invention is designed to solve this problem. To provide a new means for easily clearing a blockage when it occurs.

For this purpose, in the present invention, in the above-mentioned rice husk crusher, an end wall on the rear end side is provided at the open opening on the rear end side of the circumferential wall of the crushing barrel so as to close the opening. The present invention proposes a means for constructing a crusher for rice husks, etc. by detachably assembling the rear end of the trunk wall.
