[0002]

2. Description of the Related Art Conventionally, powdered chemicals and the like have been packed into bags and carried to and stored by a trader. However, if a large number of bags are loaded and stored for a long time, the powder inside the bags will be stored. It is necessary to grind again when it is used, etc., because the substance will crystallize and solidify, so conventionally, it was crushed from the outside of the bag body while squeezing it with a pressing machine etc. .

[0003]

However, in the pressing machine, the entire upper surface of the bag body is squeezed simultaneously with a constant pressure regardless of the amount and material of the bag body, and these operations are performed manually. Therefore, there was a problem that the bag body was damaged and the contents were scattered.

The present invention has been made to solve the above problems, and crushes solidified contents such as chemicals in a bag body easily and satisfactorily without damaging the bag body. It is to provide a crusher capable of performing.

In order to achieve the above-mentioned object, a trackless conveying means 3 for conveying the bag 1, and a trackless conveying means 3 are located so as to face the trackless conveying means 3 from the carry-in side to the carry-out side. And a pressing body 7 that is arranged in an inclined shape so as to be close to the trackless conveying means 3, and the bag body 1
Provided is a crusher capable of being fed in the conveying direction while being pressed by the pressing body 7 and the trackless conveying means 3.

According to the present invention, when the bag body 1 conveyed by the trackless conveying means 3 is sent out in the conveying direction while being pressed by the pressing body 7 and the trackless conveying means 3, the pressing body 7 carries in the conveying direction. From the side toward the carry-out side, the bag-like body 1 is gradually inclined from the leading end on the carrying-in side in the carrying direction, because the bag-like body 1 is gradually inclined so as to be close to the trackless carrying means 3. In addition, since the pressing force also gradually increases, it may be crushed little by little from the leading-in side that is carried in, and the degree of freedom of the contents inside the bag body 1 on the leading-end side may increase due to crushing. Thus, the contents in the bag body 1 can be satisfactorily crushed without damaging the bag body 1.

Here, the trackless conveying means 3 operates endlessly continuously from the carry-in side to the carry-out side and from the carry-out side to the carry-in side to carry the bag body 1 from the carry-in side to the carry-out side. After that, it means one that is returned to the loading side again, and specifically, it can be achieved by means such as a belt conveyor.

Further, the pressing body 7 can achieve the object by arranging a belt conveyor which continuously operates similarly to the trackless conveying means 3 in an inclined manner, and a plurality of rollers are arranged in an inclined manner.
