Abstract

(57) [Summary] [Problem] Since the oyster shells are crushed at the corners (lines) of the square bar, the oyster shells are well entangled, and the crushing is reliably performed. By providing different rotation speeds, an oyster hull crusher that has a grinding effect and can be crushed more finely is provided. [Solving Means] In a pulverizer in which opposing pulverizing rotary drums are provided in a pulverizer main body, a rectangular rod-shaped pulverizer is provided around the outer circumference of the pulverizing rotary drum.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement in an oyster hull crusher for processing oyster husk powder used as feed for livestock and fertilizer for agriculture.

[0002]

[Prior art]

 As a conventional technique, as shown in FIG. 6, opposing pulverizing rotary drums B, B are provided in a pulverizer main body A, and a round bar B1 provided on the outer periphery of the pulverizing rotary drums B, B There is one in which oyster shell K is thrown in from above and ground.

However, the round bar B1 receives the oyster shell K on its surface, and attempts to crush the oyster shell K only by the surface pressure in the space L between the grinding rotary drums B and B. Cannot be crushed. Also, the oyster shell K is slippery because it is received on the surface (round bar B1), and it is difficult for the oyster shell K to get into the space between the grinding rotary drums BB. Further, when the distance between the crushing rotary drums B is narrowed, a load is applied to the motor, and accidents such as burning of the motor occur frequently.

[0004]

[Problems to be solved by the invention]

 The present invention has been made in view of the above problems, and its purpose is to crush oyster shells at the corners (lines) of the square bar, so that the digging is good, so that the crushing is surely performed and the load on the motor is reduced. Instead, the present invention provides an oyster hull crusher that has a crushing effect and can be crushed more finely by configuring the crushing rotary drum to have different rotation speeds.

[0005]

[Means for Solving the Problems]

 As means for solving the problem, in a pulverizer in which opposing pulverizing rotary drums are provided in a pulverizer main body, a rectangular rod-shaped pulverizing tool is provided around the outer circumference of the pulverizing rotary drum. Further, the crusher is formed so as to be detachable. Further, the rotation speeds of the opposing grinding rotary drums are configured to be different.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The oyster shell crusher 1 has a box-shaped crusher body having a semicircular arc-shaped crushing rotary drum storage section 2a on both sides, an oyster shell input port 2b at an upper portion, and a crushed oyster shell discharge port 2c at a lower portion. The grinding rotary drum 3 in which a square rod-shaped grinding tool 3b is integrally fixed to the outer periphery of the cylindrical main body 3a by welding or the like is rotatably mounted in the grinding rotary drum storage portion 2a so as to face each other. It is made.

[0007] As an example of the use of the oyster hull crusher 1, the crushing rotary drums 3, 3 are rotated inward, and the oyster husk K1 is inserted through the oyster husk input port 2b, so that the opposing crushing tools 3b. Is finely crushed at the corner 3b1 and discharged below the ground oyster shell discharge port 2c.

Next, an oyster shell crusher according to a second embodiment will be described. The oyster shell crusher 21 is formed by integrally connecting a square bar-shaped crusher 23b having a bolt mounting hole 23b1 to a step 23a1 formed with a female screw hole 23a2 of a cylindrical main body 23a with a bolt B. The bolt B can be removed and replaced when the corner 23b2 is worn. The numbers of the female screw holes 23a2 and the bolt mounting holes 23b1 may be arbitrarily set according to the size of the cylindrical main body 23a.

Next, an oyster shell crusher according to a third embodiment will be described. The oyster shell crusher 31 sets the rotation speed of one crushing rotary drum 33A to 90 rpm / min and the other crushing rotary drum 33B to 60 rpm / min. In the case of this embodiment, by changing the number of revolutions, there is an effect of crushing and the oyster shell can be crushed more finely.

The number of crushers, the size of the cylindrical body, and the like in the above embodiment may be determined according to the amount of oyster crushed. Further, the distance of the crushing rotary drum can be reduced or expanded. Further, the number of rotations of the grinding rotary drum in the third embodiment can be changed as required.

[0011]

[Effect of the invention]

 1) Since the crusher of the present invention can crush oyster shells with a wire, it has a good bite and can be crushed reliably and efficiently. 2) The load is less likely to be applied to the motor and the like, and it is unlikely to break down. 3) Since the crusher can be changed, it can be used for a long time. 4) The oyster shell can be more finely crushed by the crushing effect of the crushing rotary drum having different rotation speeds.
