Description

Technical Field

[0001] This utility model relates to the field of waste screening technology, and in particular to a screening device for a construction waste crushing station. Background Technology

[0002] With the rapid development of urban construction and the advancement of old city renovation projects, the amount of construction waste generated is increasing daily. Construction waste crushing plants are typically used to process it. Before processing, a vibrating screen drives a screening rack to separate the materials that need to be crushed. The composition of old construction waste is complex, often containing a large amount of debris such as plastic bags or plastic films. When these debris passes through the screening rack, the thin and flexible plastic film is highly likely to become entangled in the screening rack during vibration, blocking the hollow parts of the rack. This prevents subsequent material from passing smoothly through the rack, severely affecting the efficiency and quality of the entire screening process. This results in the material screening not proceeding normally and orderly, and manual unblocking is difficult to achieve in a timely and efficient manner, while also increasing labor costs. Utility Model Content

[0003] In view of the problems existing in the screening devices of the above and / or existing construction waste crushing plants, this utility model is proposed.

[0004] Therefore, the problem to be solved by this utility model is the inconvenience of unblocking the plastic film wrapped screening frame.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides a screening device for a construction waste crushing station. The screening device for the construction waste crushing station includes a main component 100, including a screening frame 101 and a screening rack 102, with the screening rack 102 fixed inside the screening frame 101.

[0030] Vibrating screening utilizes a vibrating motor to drive the screening frame 101 and screening rack 102 to vibrate. The aged construction waste is subjected to vibration force on the screening rack 102, and begins to vibrate and move continuously. During this process, the material will gradually disperse, with smaller particles falling through the screening rack 102, while larger particles continue to move forward along the screening rack 102. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle.

[0031] The unblocking component 200 is disposed on the screening frame 101 and includes an unblocking part 201, comprising a fixed plate 201a, a slider 201b, an unblocking rod 201c, a fixed block 201d, a motor 201e, a reciprocating roller 201f, a first moving block 201g, and a locking block 201h. The fixed plate 201a is fixed to one side of the screening frame 101. A first sliding groove 201a-1 is provided in the fixed plate 201a. The slider 201b slides in the first sliding groove 201a-1. The unblocking rod 201c is fixed to one side of the slider 201b. The fixed block 201d is fixed to the outside of the unblocking rod 201c. The motor 201e is disposed on the fixed plate 201a. The reciprocating roller 201f is disposed to one side of the motor 201e. The first moving block 201g is sleeved on the outside of the reciprocating roller 201f. The locking block 201h is fixed on the first moving block 201g.

[0032] The unblocking component 201 is used to unblock the hollow part of the screening frame 102 to ensure that the plastic film does not get tangled on the screening frame 102 and cause screening blockage.

[0033] The rotating shaft inside the motor 201e is connected to the reciprocating roller 201f, so that the rotation of the motor 201e can drive the reciprocating roller 201f to rotate. A support block 201m is sleeved on one side of the reciprocating roller 201f. The support block 201m is fixed to the fixed block 201d and is used to support the reciprocating roller 201f. The locking block 201h slides in the threaded groove inside the reciprocating roller 201f. Through the cooperation between the locking block 201h and the threaded groove, when the reciprocating roller 201f rotates, it can drive the first moving block 201g to move along the direction of the reciprocating roller 201f.

[0034] The slider 201b is circular, and the first groove 201a-1 is wavy. Since the screening frame 102 is distributed in a stepped manner, the height of the unblocking rod 201c needs to be adjusted accordingly to ensure that the unblocking rod 201c is always located between the hollow parts of the screening frame 102 during unblocking and will not collide with it.

[0035] The movement of the first moving block 201g will cause the fixed block 201d to move synchronously. The fixed block 201d drives the slider 201b to move. Through the cooperation between the slider 201b and the first slide groove 201a-1, the slider 201b slides along the first slide groove 201a-1, thereby driving the unblocking rod 201c to move, thereby unblocking the hollow part of the screening frame 102. The motor 201e rotates at a relatively slow speed, thereby driving the first moving block 201g to move relatively slowly, so as to adapt to the speed of material vibration and forward movement.

[0036] Example 2

[0037] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the unblocking component 200 also includes an auxiliary component 202 located on one side of the fixed block 201d, including a telescopic rod 202a and a fixed rod 202b. The telescopic rod 202a is fixed to one side of the fixed block 201d, and the fixed rod 202b is fixed to one side of the first moving block 201g. The fixed rod 202b has a moving groove 202b-1, and the telescopic rod 202a slides in the moving groove 202b-1.

[0039] The auxiliary component 202 is used to ensure that the unblocking rod 201c can move smoothly along the predetermined track. Since the first chute 201a-1 is wavy, the distance between the unblocking rod 201c and the first moving block 201g will change. When the distance between the two is shortened, the telescopic rod 202a can slide in the moving groove 202b-1.

[0040] When the first moving block 201g reciprocates along the reciprocating roller 201f, it will drive the fixed rod 202b to move. The fixed rod 202b drives the telescopic rod 202a to move, which in turn drives the fixed block 201d to move synchronously. The fixed block 201d will drive the slider 201b and the unblocking rod 201c to move, so that the slider 201b moves along the first chute 201a-1, thereby unblocking the hollow part of the screening frame 102.

[0041] Specifically, a spring 202c is fixed to one side of the telescopic rod 202a, and the other end of the spring 202c is fixed to the inner wall of the moving groove 202b-1.

[0042] Spring 202c applies a continuous thrust to telescopic rod 202a. When the distance between unblocking rod 201c and first moving block 201g shortens, spring 202c will compress. When the distance between them increases, spring 202c will return to its original position.

[0043] Specifically, the fixed plate 201a has a second sliding groove 201a-2, a straight sliding groove 201a-3 and a third sliding groove 201a-4, and the first sliding groove 201a-1, the second sliding groove 201a-2, the straight sliding groove 201a-3 and the third sliding groove 201a-4 are connected.

[0044] The second slide 201a-2 is arc-shaped, and the third slide 201a-4 is also arc-shaped. The connecting parts of the first slide 201a-1, the second slide 201a-2, the straight slide 201a-3, and the third slide 201a-4 are all tangent to ensure that the slider 201b can slide smoothly in them.

[0045] After slider 201b passes through the first chute 201a-1, it will enter the second chute 201a-2. In the second chute 201a-2, the horizontal height of slider 201b will be raised, and the unblocking rod 201c will be raised synchronously to avoid affecting the material on the screening frame 102 during reverse movement. After the first moving block 201g moves in the reverse direction, slider 201b will enter the straight chute 201a-3, and then enter the third chute 201a-4. At this time, the horizontal level of slider 201b will decrease, and the unblocking rod 201c will be located again between the hollow parts of the screening frame 102. Slider 201b returns to its initial position and passes through the first chute 201a-1 again, thus repeating the cycle.

[0046] Specifically, the fixed plate 201a has a rotating groove 201a-5, a rotating plate 202d is provided in the rotating groove 201a-5, and a fixed post 202e is inserted into the rotating plate 202d.

[0047] The rotating groove 201a-5 is formed in the second slide groove 201a-2. The rotating plate 202d is used to limit the rotation direction of the slider 201b, ensuring that after the slider 201b enters the second slide groove 201a-2, it can enter the straight slide groove 201a-3. The fixed post 202e is fixed in the rotating groove 201a-5. The rotating plate 202d can rotate around the fixed post 202e. The end face of the rotating groove 201a-5 contacts the end face of the rotating plate 202d, which will prevent the rotating plate 202d from continuing to rotate.

[0048] Specifically, a torsion spring 202f is provided outside the fixed column 202e, and the two ends of the torsion spring 202f are fixed to the inner wall of the rotating plate 202d and the rotating groove 201a-5.

[0049] The torsion spring 202f restores the position of the rotating plate 202d. When the slider 201b moves into the second slide groove 201a-2 and contacts one end of the rotating plate 202d, as the first moving block 201g moves, the slider 201b will press against one end of the rotating plate 202d, thereby causing the rotating plate 202d to rotate. When the slider 201b continues to move along the second slide groove 201a-2 and becomes tangent to the end face of the rotating plate 202d, the slider 201b will no longer press against the rotating plate. When 202d is compressed, the torsion spring 202f will drive the rotating plate 202d to reset. The end face of the rotating groove 201a-5 will restrict the rotation of the rotating plate 202d again, while the end face of the slider 201b will contact the other end face of the rotating plate 202d. At this time, the angle of the rotating plate 202d is tangent to the arc part of the second slide groove 201a-2, so that when the first moving block 201g drives the slider 201b to move in the opposite direction, the slider 201b can move into the straight slide groove 201a-3.

[0050] Example 3

[0051] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, a support plate 201i is fixed on the screening frame 101, a slide rod 201j is fixed on one side of the support plate 201i, and a second moving block 2010k is fitted over the slide rod 201j.

[0053] The support plate 201i is used to support the slide bar 201j, and the second moving block 2010k can slide on the slide bar 201j.

[0054] Specifically, there are two sets of telescopic rods 202a and fixed rods 202b, one of which is located on one side of the second moving block 2010k.

[0055] When the first moving block 201g drives the slider 201b and the unblocking rod 201c to move, the other end of the unblocking rod 201c will also move synchronously, thereby causing the second moving block 2010k to slide along the sliding rod 201j, and the height of the other end of the unblocking rod 201c can also change accordingly, so as to ensure that the unblocking rod 201c moves smoothly and improves the smoothness of unblocking.

[0056] Specifically, comb teeth 201l are fixed on the unblocking rod 201c.

[0057] There are multiple comb teeth 201l located between the hollow parts of the screening frame 102. When the unblocking rod 201c moves, the plastic film stuck in the hollow position of the screening frame 102 will be pushed forward by the comb teeth 201l, thereby unblocking the hollow part of the screening frame 102 and preventing screening blockage.

[0058] Specifically, the main component 100 includes a feed hopper 103, a conveyor belt 104, and a conveyor belt 105. The feed hopper 103 is located on one side of the screening frame 101, the conveyor belt 104 is located inside the feed hopper 103, and the conveyor belt 105 is located on one side of the screening frame 101.

[0059] The aged construction waste first enters the feed hopper 103 and then enters the screening frame 101 via the conveyor belt 104. After screening, the material passes through multiple screening frames 102 and then falls onto the conveyor belt 105 to move to the next processing step. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0060] In use, the starting motor 201e drives the reciprocating roller 201f to rotate, causing the first moving block 201g to move along the direction of the reciprocating roller 201f. The first moving block 201g will drive the fixed rod 202b to move, and drive the telescopic rod 202a to move, which in turn drives the fixed block 201d to move synchronously. The fixed block 201d will drive the slider 201b and the unblocking rod 201c to move, so that the slider 201b moves along the first chute 201a-1. At this time, the unblocking rod 201c and the comb teeth 201l move, thereby unblocking the hollow part of the screening frame 102.

[0061] When slider 201b moves into the second slide groove 201a-2 and contacts one end of rotating plate 202d, rotating plate 202d rotates, and torsion spring 202f is compressed. When slider 201b is tangent to the end face of rotating plate 202d, slider 201b no longer presses on rotating plate 202d, and torsion spring 202f will drive rotating plate 202d to reset. Rotating groove 201a-5 restricts the rotation of rotating plate 202d, so that when the first moving block 201g drives slider 201b to move in the opposite direction, slider 201b can move into linear slide groove 201a-3, and then move along linear slide groove 201a-3 to the third slide groove 201a-4, and then enter the first slide groove 201a-1 again, thus repeating the cycle.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
