Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pelletizing device for poultry manure or the like, and more specifically, it is a raw material for poultry manure or the like, which is compressed in multiple stages by a plurality of rollers provided with annular grooves or annular convex portions to form a string. The present invention relates to a pelletizing device for poultry manure or the like, which is capable of producing pellets by molding and cutting the obtained cord-shaped raw material into pieces each having a required length.

[0002]

2. Description of the Related Art Chicken manure, cow manure, pig manure, etc. are fermented and used as fertilizer in a dried state to a required water content (about 20 to 30%). Fertilizers obtained by fermenting and drying chicken manure and the like are inferior in handling because the shapes and grains are not uniform as they are, and therefore, they are pelletized. As a device for pelletizing this fertilizer, for example, a device shown in FIG. 7 is known. This apparatus is provided with two compression rollers 90, 90 which are formed in a cylindrical shape and have a large number of communication holes 90a communicating in the radial direction on the peripheral surface, which are parallel to each other. It is designed to be driven to rotate in mutually opposite directions. In addition, a shaft member 96 having a plurality of cutting blades 94 mounted at predetermined intervals in the circumferential direction coaxially faces the hollow inside of each compression roller 90, and the shaft member 9
The compression roller 90 is configured to relatively rotate around 6. The open end of the cutting blade 94 is set to be in sliding contact with the inner peripheral surface of the compression roller 90.

That is, by feeding the raw materials such as fermented and dried chicken manure between the compression rollers 90 and 90 while the compression rollers 90 and 90 are being rotated, the raw materials are compressed. It is compressed by 90 and 90, and is forcedly passed through the communication holes 90a and 90a, so that it is extruded inside the rollers 90 and 90 in a string shape. Then, the cord-shaped raw material is cut into the required length by the relative rotation of the cutting blade 94 and the compression roller 90, whereby the raw material is pelletized.

[0004]

In the pelletizing apparatus described above, the fermented and dried raw material is forcedly passed through the communication hole 90a of the compression roller 90 to be formed into a string-like shape. It is necessary to increase the contact pressure between 90 and 90. In this case, the compression roller 9
As described above, the rollers 0 and 90 are formed hollow so that the cutting blade 94 is provided therein and a large number of communication holes 90a are formed therein. It could be deformed or damaged in a short time. Further, by forcibly passing the raw material through the communication hole 90a, the communication hole 90a is worn in a short period of time,
The desired size of pellets cannot be obtained. That is,
It is pointed out that the compression roller 90 needs to be frequently repaired or replaced, which increases the running cost. In addition, since both rollers 90, 90 are rotationally driven under the condition that the contact pressure between both compression rollers 90, 90 is set to be large, the drive source thereof must be large in size and high in output, so that the apparatus becomes large. At the same time, there is a problem that the manufacturing cost increases.

Next, the operation of the pelletizing apparatus for poultry manure or the like according to this embodiment will be described. In the pelletizing apparatus 10, as shown in FIG. 1, the raw material 26 is sequentially fed from a storage tank (not shown) via the belt conveyor 36 extending above the frame 11. The raw material 26 is supplied to the hopper 41 located above the compression device 12, and then, as shown in FIG.
It is supplied between the sub roller 20. The raw material 26 is formed into a string shape while being compressed by the gap W ₁ between the annular groove 18 a of the main roller 18 and the annular member 21 of the second roller 20. The string-shaped raw material 26 is then supplied between the main roller 18 and the second sub roller 22 and further compressed by the gap W ₂ between the annular groove 18 a and the annular member 23. Next, the cord-shaped raw material 26 is mixed with the main roller 18 and the third roller.
By being supplied between the sub-roller 24 and further compressed by the gap W ₃ between the annular groove 18a and the annular member 25,
The raw material 26 is compression-molded into a string having a desired thickness. Since each of the sub rollers 20, 22, and 24 is a driven roller that rotates following the main roller 18, the raw material 26 is favorably compressed between the opposing rollers. Further, since the annular members 21, 23, 25 of the sub rollers 20, 22, 24 are externally fitted so as to be able to move slightly in the axial direction, the raw material 26 is firmly bonded to the annular groove 18 of the main roller 18.

On the other hand, in the rotary blade 56 approaching the fixed blade 58 by the rotation of the drive roller 54,
As shown in (a), the guide rollers 70, 70 attached to both ends of the cleaner 66 in the longitudinal direction are attached to the guide plate 7.
The intermediate part 72 is in contact with the entry sides 72a, 72a of the 2,72.
By moving to c, 72c, the cleaner 66 is pushed inward from the tip of the rotary blade 56. As a result, the cut end of the rotary blade 56 is exposed. Then, by the rotary blade 56 passing below the fixed blade 58,
The string-shaped raw material 26 facing between the blades 56 and 58 is cut. In the process in which the rotary blade 56 that has completed the cutting operation moves to the downstream side in the rotation direction, the guide roller 70 of the cleaner 66,
70 moves from the intermediate portions 72c, 72c of the guide plates 72, 72 to the retreat sides 72b, 72b, whereby the cleaner 66 is radially outward along the front side surface of the rotary blade 56 under the elastic force of the compression spring 68. Move towards. Therefore, the rotary blade 5
The raw material 26 adhering to the front surface of 6 is a cleaner 66.
It is possible to prevent it from being scraped off and hindering the next cutting work.

The string-shaped raw material 26 guided and supplied to the cutting device 14 is cut at the length supplied while the next rotary blade 56 reaches the cutting position with the fixed blade 58 (see FIG. 6 (b)), the cutting length of the string-shaped raw material 26 can be adjusted by changing the rotation speed of the drive roller 54.

The pellets obtained by cutting the cord-shaped raw material 26 by the cutting device 14 are discharged to the bottom of the housing 62 and then transferred to the duct 82 via the screw 60. This pellet is supplied to the sorting basket 74 via a duct 82,
By rotating 4, the small-sized pellets, which have lost their shape during movement and have become smaller than the desired size, are separated and fall and accumulated in the lower tray 88. Saucer 88
The small-sized pellets collected in 1. are returned to the storage tank by the suction pump 84 and provided for pelletization again,
This makes it possible to reduce the yield.

In the embodiment, the case where three sub rollers for compressing the raw material between the main roller and the main roller are provided has been described, but the present invention is not limited to this, and two or four rollers are provided.
You may make it arrange | position the sub roller more than a base. Also,
The small-sized pellets sorted by the sorting basket may be returned to the hopper via a suction pump. Further, instead of the suction pump, it may be returned to the storage tank or the hopper by a conveying means such as a belt conveyor. Further, in the embodiment, the annular convex portion is provided by externally fitting the annular member on the shaft portion of the sub roller, but the annular convex portion may be formed integrally with the sub roller.
