For this reason, as shown in fig. 5 and 10, the present application further enhances the crushing effect by arranging the projections 5a to be inclined on the inner wall of the centrifugal cylinder 5 so that the transfer passage formed between each two projections 5a is also inclined, thereby reducing the transfer speed of the coal mine and increasing the number of times of contact between the coal mine and the second stirring rod 6 d.
Further:
one side of centrifugal cylinder 5 is provided with third support 5b that is used for supporting centrifugal cylinder 5, is provided with two evenly distributed's second slider 5b1 on the third support 5b, all is provided with two evenly distributed's third screw hole on every second slider 5b1, be provided with on the dust cover 2 with second slider 5b1 the same and the second spout 2h of one-to-one, second spout 2h top is provided with the fourth screw hole the same with third screw hole quantity and one-to-one.
Based on the above embodiments, the technical problem that the present application intends to solve is how to facilitate the maintenance of the centrifuge bowl 5. Therefore, as shown in fig. 11, the third bracket 5b can be conveniently inserted into the second chute 2h through the second sliding block 5b1 by the second chute 2h and the second sliding block 5b1, so that the third threaded hole and the fourth threaded hole are overlapped and an external bolt is inserted for fixing, and the centrifuge tube 5 can be conveniently detached for maintenance.
Further:
a plurality of second reinforcing ribs 2i which are uniformly distributed and obliquely arranged are arranged on the outer surface of the dustproof shell 2.
Based on above-mentioned embodiment, the technical problem that this application wanted to solve prevents that the dustproof support collision from taking place deformation and influence inside work. For this reason, as shown in fig. 1, the outer surface of the dust-proof housing 2 is supported by the second reinforcing ribs 2i, so that the supporting effect is enhanced, and the dust-proof housing 2 is prevented from being deformed due to collision.
The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
