[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0036] Example:

[0037] like Figures 1-5 As shown, an adjustable screening device for sand treatment includes:

[0038] Vibrating screen 1 has a rectangular feeding trough at the top and discharge troughs on both sides;

[0039] Screening adjustment mechanism 2 is fixedly installed on the inner side of vibrating screen 1;

[0040] The discharge assembly 3 is fixedly installed inside the vibrating screen 1 and located below the screening adjustment mechanism 2;

[0041] Fixed guide block 4 is symmetrically arranged on the inner bottom of vibrating screen 1;

[0042] The discharge chute 5 is located at the bottom inner side of the vibrating screen 1;

[0043] The feeding control mechanism 6 is fixedly installed on the top of the vibrating screen 1.

[0044] The working principle of the above technical solution is as follows:

[0045] During use, the feeding control mechanism 6 is first adjusted so that the sand can move into the vibrating screen 1 through the feeding control mechanism 6. The sand is then screened by the screening adjustment mechanism 2, and the screened sand can be discharged to the outside through the discharge component 3. Finally, the screened sand can be guided by the fixed guide bottom block 4 and discharged to the outside through the discharge channel 5. At the same time, the screening adjustment mechanism 2 can be adjusted so that the inclination of the screening adjustment mechanism 2 can be adjusted so that the screening adjustment mechanism 2 is in a relatively flat state, thereby prolonging the time that the sand is at the top of the screening adjustment mechanism 2, so as to fully screen the sand. The operation is convenient.

[0046] In another embodiment, such as Figure 3 As shown, the screening adjustment mechanism 2 includes a fixed mounting base 21. A movable mounting frame 22 is movably connected to the inner side of the fixed mounting base 21 via a connecting shaft. A screening screen 23 is fixedly connected to the upper inner side of the movable mounting frame 22. A first connecting seat 24 is fixedly connected to the inner side of the movable mounting frame 22. A first movable connecting block 25 is movably connected to the inner side of the first connecting seat 24 via a connecting shaft. A second connecting seat 28 is fixedly connected to the inner side of the vibrating screen 1. A second movable connecting block 27 is movably connected to the second connecting seat 28 via a connecting shaft. An electric telescopic rod 26 is fixedly connected between one end of the second movable connecting block 27 and one end of the first movable connecting block 25.

[0047] The electric telescopic rod 26 can push the first movable connecting block 25 and the first connecting seat 24, allowing the movable mounting frame 22 and the screening screen 23 to deflect inside the fixed mounting seat 21, thus adjusting the tilt of the movable mounting frame 22 and the screening screen 23. At the same time, the first movable connecting block 25 can deflect inside the first connecting seat 24, and the second movable connecting block 27 can deflect inside the second connecting seat 28, thereby making adjustment convenient.

[0048] In another embodiment, such as Figure 3 As shown, the discharge assembly 3 includes a guide discharge plate 31, and a fixed reinforcing arm 32 is symmetrically provided between the top edge of the portion of the guide discharge plate 31 located inside the vibrating screen 1 and the inner side of the vibrating screen 1.

[0049] After the sand is screened by the screening mesh 23, the screened sand can fall to the inside of the guide discharge plate 31 and be quickly discharged to the outside under the guidance of the guide discharge plate 31. At the same time, the fixed reinforcing arm 32 can be connected to the inner wall of the vibrating screen 1 to reinforce the guide discharge plate 31 and improve the stability of the guide discharge plate 31.

[0050] In another embodiment, such as Figure 4As shown, the feeding control mechanism 6 includes a feeding funnel 61. A rectangular through groove 62 is provided on one side of the lower part of the feeding funnel 61. A movable cover 63 is movably sleeved on the outer side of the top surface of the feeding funnel 61. A transparent acrylic plate 64 is provided inside the top of the movable cover 63. A first handle 65 is symmetrically provided on the top of the movable cover 63. A movable sealing plate 66 is movably connected to the inner side of the rectangular through groove 62. A connecting end plate 67 is fixedly connected to one side of the movable sealing plate 66. Both ends of the connecting end plate 67 are fixedly connected to connecting... The connecting arm 68 and the connecting end plate 67 are fixedly connected to a fixed limiting mechanism 614 on one side away from the movable sealing plate 66. The bottom outer side of the feeding funnel 61 is symmetrically provided with connecting mounting blocks 610. A fixed guide rod 611 is fixedly connected to one side of the connecting mounting block 610. A fixed limiting plate 612 is fixedly connected to one end of the fixed guide rod 611 away from the connecting mounting block 610. A connecting limiting block 613 is fixedly connected to one side of the fixed limiting plate 612 away from the fixed guide rod 611.

[0051] The first handle 65 is pulled upwards to move the movable cover 63 and the transparent acrylic plate 64, causing the movable cover 63 to detach from the top of the feeding funnel 61. Then, the second handle 69 is pulled to move the connecting end plate 67, the movable sealing plate 66, the fixed limiting mechanism 614, and the connecting end arm 68, allowing the end of the connecting end arm 68 to move outside the surface of the fixed guide rod 611. At the same time, the fixed limiting mechanism 614 and the connecting limiting block 613 separate, allowing the movable sealing plate 66 to open the lower inner side of the feeding funnel 61, facilitating the stable addition of sand into the vibrating screen 1 through the feeding funnel 61. When no sand is added, the entire structure can be reset to prevent impurities from the outdoor environment from entering and blocking the screening screen 23, ensuring stable operation and ease of use.

[0052] In another embodiment, such as Figure 5 As shown, the fixed limiting mechanism 614 includes a mounting sleeve 6141. A force spring 6142 is fixedly connected inside the mounting sleeve 6141. A connecting mounting plate 6143 is fixedly connected to one end of the force spring 6142. A connecting mounting rod 6144 is fixedly connected to the side of the connecting mounting plate 6143 away from the force spring 6142. A limit clamp 6145 is fixedly connected to the end of the connecting mounting rod 6144 away from the connecting mounting plate 6143.

[0053] During the process of separating the fixed limiting mechanism 614 from the connecting limiting block 613, the limiting head 6145 and the connecting limiting block 613 are pressed against each other, causing the limiting head 6145 to move, which in turn drives the connecting mounting rod 6144 and the connecting mounting plate 6143 to move, compressing the force spring 6142, thereby adjusting itself and making it convenient to use.

[0054] In another embodiment, such as Figure 5 As shown, the connecting limit block 613 has a slot on the side near the limit card head 6145 that is adapted to the limit card head 6145.

[0055] This allows the limiting head 6145 to be stably locked inside the connecting limiting block 613, thereby enabling connection limiting.

[0056] In another embodiment, such as Figure 4 As shown, the inner end of the connecting arm 68 slides against the outer surface of the fixed guide rod 611.

[0057] This allows the end of the connecting arm 68 to move stably on the outer side of the fixed guide rod 611, making operation convenient.

[0058] The working principle of this utility model is as follows: During use, the first handle 65 is pulled upwards, causing the movable cover 63 and the transparent acrylic plate 64 to move, so that the movable cover 63 detaches from the outer side of the top surface of the feeding funnel 61. Then, the second handle 69 is pulled, causing the connecting end plate 67, the fixed limiting mechanism 614, the connecting end arm 68, and the movable sealing plate 66 to move. During the separation of the fixed limiting mechanism 614 and the connecting limiting block 613, the limiting head 6145 and the connecting limiting block 613 are pressed against each other, causing the limiting head 6145 to move, which in turn causes the connecting mounting rod 6144 and the connecting mounting plate 6143 to move, compressing the force spring 6142, thereby adjusting itself so that the end of the connecting end arm 68 is in contact with the fixed limiting plate 612. The movable sealing plate 66 then closes the inner bottom end of the feeding funnel 61. When the screen is opened, sand is added to the inside of the vibrating screen 1 through the feeding funnel 61. The sand is then screened by the screening adjustment mechanism 2. When a large amount of sand is added, the electric telescopic rod 26 can push the first movable connecting block 25 and the first connecting seat 24, causing the movable mounting frame 22 and the screening screen 23 to deflect inside the fixed mounting seat 21. This adjusts the inclination of the movable mounting frame 22 and the screening screen 23. At the same time, the first movable connecting block 25 can deflect inside the first connecting seat 24, and the second movable connecting block 27 can deflect inside the second connecting seat 28. This adjustment allows the movable mounting frame 22 and the screening screen 23 to be at a relatively gentle angle, so that the sand can stay on top of the screening screen 23 for a longer time, thus fully screening the sand. The overall structure is simple and the operation is convenient and quick.

[0059] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
