Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details.
Referring to fig. 1, a rolling-type double-roller green ball crusher comprises a green ball conveyer belt 1, a first crushing roller 2 and a second crushing roller 3; the first crushing roller 2 is arranged above the green ball conveying belt 1 in a vertically adjustable manner through a first mounting assembly, and a gap is formed between the roller surface of the first crushing roller 2 and the upper end surface of the green ball conveying belt 1; the second crushing roller 3 is arranged below the green ball conveying belt 1 through a second mounting component, and the roller surface of the second crushing roller 3 is mutually abutted with the lower end surface of the green ball conveying belt 1; the first crushing roller 1 and the second crushing roller 2 rotate relatively under the friction action of the green ball conveying belt 1 and the green balls A, so that the green balls are crushed. The utility model discloses simple structure, convenient operation, the transmission between the pair roller comes from the frictional force between green ball conveyer belt 1 and the green ball A, need not additionally to dispose the motor to crushing effect is good, and equipment is reliably durable, easy to maintain.
Referring to FIG. 1, in particular, the first mounting assembly includes a bracket 21, an L-shaped connecting arm 22 and a first bearing housing 23; the v-shaped bracket 21 transversely spans the green ball conveying belt 1; one end of the L-shaped connecting arm 22 is pivoted to the bracket 21274, the two sides of the other end of the L-shaped connecting arm 22 are symmetrically and fixedly provided with a first bearing seat 23; between the two first bearing blocks 23 a first crushing roller 2 is rotatably mounted. A driving mechanism for vertically turning the L-shaped connecting arm 22 is also included. As a preferable scheme: the driving mechanism is a hand-operated hoist 24; a hanging ring 221 is fixedly arranged in the middle of the other end of the L-shaped connecting arm 22; the hand hoist 24 is arranged on the top of the 21274H-shaped bracket 21, and the hoisting chain 241 of the hand hoist 24 is fixedly connected with the hoisting ring 221.
