In an embodiment, the first cutter and the second cutter are provided with second threaded holes corresponding to each other, and the first cutter and the second cutter can be fixed by passing through the first threaded hole and the second threaded hole through bolts.

The connection between the cutter and the fixed block can be reinforced by respectively arranging the threaded holes in the first fixed groove and the second fixed groove, and the corresponding threaded holes are also arranged on the cutter, so that the first cutter and the second cutter are directly connected, and the cutter can be further prevented from loosening.

In one embodiment, a side of the connecting end, which is close to the cutter end, is provided with a crushing end which inclines downwards, and the crushing end is connected with the cutter end to form a cutter head.

In one embodiment, the height of the fixing block is smaller than that of the cutter body, and the distance between the upper end surface of the fixing block and the upper end surface of the cutter body is equal to the distance between the lower end surface of the fixing block and the lower end surface of the cutter body.

Detailed Description

The present invention is further illustrated by the following description in conjunction with the accompanying drawings, which are to be construed as merely illustrative and not limitative of the remainder of the disclosure, and on reading the disclosure, various equivalent modifications thereof will become apparent to those skilled in the art and fall within the limits of the appended claims.

As shown in fig. 1, 2 and 4, the split type cutter comprises a cutter body 1, a plurality of fixing blocks 2 are mounted on the outer circumference of the cutter body 1, each fixing block 2 comprises a first fixing end 201 and a second fixing end 202, the first fixing end 201 is higher than the second fixing end 202, and the first cutter 3 is sleeved on the fixing blocks 2.

Since the first cutter 3 and the second cutter have the same shape, the first cutter 3 will be explained as an example.

As shown in fig. 3, a first fixing groove 307 adapted to the fixing block 2 is formed in the first cutter 3, a plurality of first threaded holes 305 are formed in the first fixing groove 307, the first cutter 3 can penetrate through the first threaded holes 305 through bolts to be screwed with the fixing block 2, it should be noted that the first cutter 3 needs to be connected with the first fixing end 201 and the second fixing end 202 of the fixing block 2 in a shape adapting manner when being installed, a slope connecting the first fixing end 201 from the second fixing end 202 in an inclined manner can be formed by the height of the first fixing end 201 higher than the height of the second fixing end 202, the slope can prevent the cutter from being thrown out when rotating, and meanwhile, a part of the force borne by the cutter during crushing can be distributed to the fixing block to prevent the bolts from being cut off.

In an embodiment, the first cutter and the second cutter are provided with second threaded holes 306 opposite to each other, and when the first cutter and the second cutter are mounted, the first cutter and the second cutter can be further fixedly connected by mounting bolts on the second threaded holes 306.

It should be understood that the connection manner of the first cutting knife and the fixing block is not limited to the screw connection manner, and the connection may also be performed by other manners such as clamping, inserting and the like.

In one embodiment, the height of fixed block 2 is less than the height of cutter body 1, and the distance of the up end of fixed block 2 and the up end of cutter body 1 equals with the distance of the end face under fixed block 2 and the cutter body 1, and above-mentioned design mainly can leave one section space and be used for installing the cutter to when the installation, can find cutter hookup location through above-mentioned difference in height, more easy to assemble.

In one embodiment, in order to make it easier for the cutter to break the straw, the first cutter 3 includes a cutter end 302 and a tail end 303, and a connecting end 304 connecting the cutter end 302 and the tail end 303, the end surfaces of the cutter end 302 and the tail end 303 form an acute angle with each other, the height of the tail end 303 is shorter than the height of the cutter end 302, the connecting end 304 is connected to the cutter end 302 obliquely upward from the tail end 303, an oblique connecting end 304 can be formed by the above design, the connecting end 304 can facilitate that the straw particles can form a circular flow along the extending direction of the connecting end 304 during cutting and breaking, so as not to stir the particles into the chopper, in order to obtain a sharper cutter head, the side of the connecting end 304 close to the cutter end 302 is provided with a downwardly inclined breaking end 301, the breaking end 301 is connected with the cutter end 302 to form a cutter head 308, and the cutter head 308 becomes sharper by the composition of the breaking end 301 and the cutter end 302, the straw is easier to be crushed.
