DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] The utility model provides a technical solution: a highway sand and gravel vibration screening machine, including a vibration screen body 1, a vibration screen base frame 2 is provided below the vibration screen body 1, a feeding device base frame 3 is provided behind the vibration screen base frame 2, and a feeding device 4 is provided on the side of the feeding device base frame 3 above the vibration screen body 1. A hopper 5 is provided on the side above the feeding device base frame 3 away from the vibration screen body 1, and a waste box 6 is provided below the hopper 5 in the middle of the feeding device base frame 3; a hollow bottom plate 51 is provided at the bottom of the hopper 5, and a hopper discharge port 52 is provided on the side of the hollow bottom plate 51 close to the feeding device 4. When in use, after sand and gravel are put into the hopper, part of the waste will fall into the waste box 6 through the hollow bottom plate 51, and the rest of the sand and gravel will fall onto the feeding device 4 through the hopper discharge port 52, thereby achieving the purpose of preliminary screening; the feeding device 4 includes a conveyor belt outer frame 41, a driving wheel 42 is provided at the bottom end of the conveyor belt outer frame 41, and a driving wheel 42 is provided at the bottom end of the conveyor belt outer frame A driven wheel 43 is provided on the side of 41 away from the driving wheel 42, and a motor 44 is provided at the bottom of the feeding device chassis 3 close to the vibrating screen chassis 2. The motor 44 and the driving wheel 42 are connected by a conveyor belt 441, and a protective cover 442 is provided on the outside of the conveyor belt 441. A conveyor belt 45 is tensioned between the driving wheel 42 and the driven wheel 43, and conveyor belt baffles 46 are provided on both sides of the conveyor belt 45. The conveyor belt baffles 46 are fixedly connected to the conveyor belt outer frame 41, and the conveyor belt baffle 46 on the left side is provided with a protrusion 461 close to the conveyor belt 45. A number of vibrating parts 47 are evenly provided on the conveyor belt 45. The vibrating member 47 includes a pocket plate fixing block 471, a chute 472 is opened inside the pocket plate fixing block 471, a spring 474 is provided on the right side of the chute 472, the pocket plate fixing block 471 is clamped with a pocket plate 475, and a soft plate 476 is connected to the right side of the pocket plate 475. When in use, the motor 44 drives the driving wheel 42 to rotate through the conveyor belt 441, and the driving wheel 42 and the driven wheel 43 rotate the tensioned conveyor belt 45. When the material falls onto the conveyor belt, it is caught by the vibrating member 47. When the vibrating member 47 climbs with the conveyor belt 45 and passes the position with the protruding block 461, the pocket plate 475 is forced to slide to the right in the chute 472 of the pocket plate fixing member 471. , the extrusion spring 474 and the soft plate 476 are deformed, and the spring 474 is reset after passing through the protrusion block 461 to push the pocket plate 475 to slide to the left, completing a left and right vibration, so that the sand and gravel are distributed more evenly on the pocket plate, and some waste is screened out. The screened waste falls into the waste box 6 at the bottom through the screening slot 473, and the remaining sand and gravel are evenly transported to the screening machine body 1 for further screening. The uniform feeding of sand and gravel by the feeding device 4 can effectively improve the working efficiency and quality of the vibrating screening machine, and the pre-screening treatment of sand and gravel by the hollow bottom plate 51 of the hopper 5 and the vibrating member 47 can make the quality of the sand and gravel finally screened out higher.

[0023] Example 2

[0024] In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the soft plate 476 is made of a rubber material with high elasticity, high wear resistance and flexural resistance. When passing through the protrusion block 461, the pocket plate 461 is squeezed and slides to the right in the slide groove 472. The deformation of the soft plate 476 made of rubber material with high elasticity will not hinder the sliding of the pocket plate 461. After passing through the protrusion block 461, the spring 474 is reset, the pocket plate 461 slides to the left in the slide groove 472, and the soft plate 476 returns to its original state, which can prevent sand and gravel from falling. The rubber material with high wear resistance and flexural resistance can greatly improve the service life of the soft plate 476.
