DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] A screening device for building material processing and batching comprises a body 1, a screen 2 is fixedly arranged on the inner wall of the body 1, a material turning mechanism is arranged inside the body 1, the material turning mechanism comprises a shovel 3, a motor 4, a rotating shaft 5, a traction seat 6, a limit seat 18 and a spring 19, the motor 4 is fixed to the top of the body 1, the rotating shaft 5 is rotatably arranged on the top of the inner cavity of the body 1 and is keyed to the output end of the motor 4, the traction seat 6 is slidably arranged on the surface of the rotating shaft 5 through a limit assembly, the limit seat 18 is fixed to the surface of the rotating shaft 5, the spring 19 is fixed between the limit seat 18 and the traction seat 6 and is sleeved on the surface of the rotating shaft 5, two shovels 3 are fixed to the side surfaces of the traction seat 6 in a centrally symmetrical manner, the shovels 3 are cooperatively connected to the body 1 through a lifting assembly, the bottom of the body 1 is arranged in a conical structure, and a discharge port 16 is arranged at the bottom of the body 1, and a feed port 17 is fixedly arranged on the top of the body 1.

[0028] See also Figure 1 , 2 The traction seat 6 can drive the material shovel 3 to move up to the highest point through the lifting assembly during rotation. During this process, the traction seat 6 and the limit seat 18 continuously compress the spring 19. When the material shovel 3 just enters the next lifting assembly, the spring 19 drives the material shovel 3 to reset through its own elastic force, which enables the material shovel 3 to perform vertical reciprocating motion while revolving. Since the bottom of the material shovel 3 is set in an inclined state, when there is a lot of material in the machine body 1, the material shovel 3 can lift a part of the material and then descend and reset while revolving, thereby realizing continuous turning of the material for the convenience of material screening.

[0029] The limiting assembly includes a sliding block 7 fixedly arranged on the inner wall of the traction seat 6 and a sliding groove 8 arranged on the surface of the rotating shaft 5 , and the sliding block 7 is slidably arranged in the sliding groove 8 .

[0030] See also Figure 5 The slider 7 and the slide groove 8 are arranged so that the rotating shaft 5 can drive the traction seat 6 to rotate circumferentially, and the slider 7 can move vertically inside the slide groove 8 through the arrangement of the lifting assembly.

[0031] The lifting assembly includes a lifting block 9 fixed to the side of the shovel 3, and a plurality of tracks 10 arranged on the inner wall of the body 1. The plurality of tracks 10 are in a spiral upward trend. The starting end of the track 10 is located directly below the end of the adjacent track 10. A shock-absorbing rubber pad 11 is fixed at the starting end of the track 10.

[0032] See also Figure 2 , 3 And 6, the lifting block 9 can revolve synchronously with the shovel 3. When the lifting block 9 revolves, it will always fit the top of the track 10 under the compression of the spring 19. Since the track 10 has a spiral upward trend, the lifting block 9 can continuously move up along the track 10, thereby driving the shovel 3 to continuously move up. At this time, the shovel 3 can drive a part of the material to move up. The movement of the lifting block 9 from the beginning to the end of the track 10 is a complete ascending process. When the shovel 3 reaches the highest point, the shovel 3 drives the lifting block 9 to continue to revolve. At this time, the lifting block 9 will fall to the beginning of the next track 10 under the action of gravity and contact with the shock-absorbing rubber pad 11. The shock-absorbing rubber pad 11 can protect the lifting block 9 at this time.

[0033] Embodiment 2:

[0034] In the above scheme, the material is turned over by the revolution and vertical reciprocating motion of the shovel 3, but the turning angle and method are limited. Therefore, in this embodiment, an auxiliary mechanism is arranged in the shovel 3, and the auxiliary mechanism includes a driving plate 12 elastically and movably arranged on the inner wall of the shovel 3, and a plurality of push plates 13 vertically fixed on the driving plate 12. The plurality of push plates 13 are equidistantly distributed on the surface of the driving plate 12. One end of the driving plate 12 penetrates the shovel 3 and the slider 7 and cooperates with the rotating shaft 5 through the driving assembly. The driving assembly includes a first wave portion 14 and a second wave portion 15. The first wave portion 14 is arranged at one end of the driving plate 12, and the second wave portion 15 is arranged on the inner wall of the slide groove 8. The first wave portion 14 and the second wave portion 15 are staggered and engaged with each other.

[0035] See also Figure 4 When the traction seat 6 drives the shovel 3 to reciprocate vertically, it can drive the driving plate 12 and the push plate 13 to move synchronously. One end of the driving plate 12 can slide inside the slide groove 8. When the driving plate 12 moves, it can drive the first wave portion 14 to move synchronously. When the first wave portion 14 rises, it can cooperate with the second wave portion 15 to drive the driving plate 12 to move horizontally. Since the other end of the driving plate 12 is elastically connected to the shovel 3, it can continuously drive the driving plate 12 to reciprocate horizontally as the driving plate 12 moves upward, thereby driving the five push plates 13 to move synchronously through the driving plate 12, thereby assisting the shovel 3 to flip the material.

[0036] It should be noted that the elastic and movable connection between the driving plate 12 and the shovel 3 is mostly achieved through the spring 19. This connection method is a technical means well known to those skilled in the art and will not be described in detail here.

[0037] Working principle: the material is introduced into the machine body 1 through the feed port 17, and the motor 4 is started. The motor 4 can drive the rotating shaft 5 to rotate, and the rotating shaft 5 can drive the shovel 3 to rotate through the traction seat 6. When the shovel 3 rotates, it can drive the lifting block 9 to rotate. When the lifting block 9 rotates, it can continuously move up along the track 10, thereby driving the shovel 3 to continuously move up. At this time, the shovel 3 can drive a part of the material to move up, and compress the spring 19 through the traction seat 6 and the limit seat 18 to deform and store energy. When the lifting block 9 enters the next track 10, the spring 19 resets and releases energy, thereby tending to reset the shovel 3. In this process, the traction seat 6 can cooperate with one end of the driving plate 12 to be elastically connected with the shovel 3 through the first wave portion 14 and the second wave portion 15, so as to drive the push plate 13 to perform horizontal reciprocating motion inside the shovel 3, thereby realizing continuous turning of the material. The turned material can be evenly distributed on the screen 2 for screening, and finally discharged from the machine body 1 through the discharge port 16.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
