[0002] In the casting production process, the quality of molding sand has a crucial impact on the quality of castings. Therefore, sand screening machines are used for screening. A sand screening machine is a sand mining machine that uses screening equipment to separate coarse and fine materials. The raw material mixture enters the equipment through a feeding device. After being screened by the screen, larger stone particles are blocked above the screen, while smaller sand particles fall through the screen holes to the bottom of the screen, thus achieving the separation of sand and gravel.

[0003] Existing patent (publication number: CN219851989U) discloses a sand screening machine. A sand collecting plate A is fixed to wall plate B. The longitudinal section of sand collecting plate A is U-shaped, and the width of one end connected to wall plate B is greater than the width of the other end. Large particles of molding sand discharged from sand outlet A are collected by sand collecting plate A. A sand collecting plate B is fixed to wall plate D. The longitudinal section of sand collecting plate B is U-shaped, and the width of one end connected to wall plate D is greater than the width of the other end. Large particles of molding sand discharged from sand outlet B are collected by sand collecting plate B. This utility model, by setting sand collecting plates A and B, facilitates the accumulation of molding sand after it is discharged from the frame, further facilitating the recycling of molding sand.

[0004] While existing patents offer solutions to address the aforementioned issues, their methods suffer from low screening accuracy, low screening efficiency, and poor equipment reliability and stability in practical applications. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, 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 embodiment or an embodiment selectively excluded from other embodiments.

[0028] Please see Figures 1-5 This embodiment provides a reciprocating mobile sand screening machine, which includes a mobile frame 1, a feeding trough 2 and a connecting plate 3. The feeding trough 2 is opened on the inner wall of the mobile frame 1, and the connecting plate 3 is fixedly installed on one side of the inner side of the feeding trough 2.

[0029] The reciprocating mobile sand screening machine also includes a screening mechanism 4 and a scraping mechanism 5. The screening mechanism 4 is located at the top of the mobile frame 1, and the scraping mechanism 5 is located on one side of the screening mechanism 4.

[0030] Specifically, the screening mechanism 4 includes a motor 401, which is fixedly installed on the top of the movable frame 1. A flywheel assembly 402 is fixedly installed on the power output end of the motor 401, and a belt 403 is sleeved on the outer wall of the flywheel assembly 402.

[0031] Furthermore, the flywheel assembly 402 is equipped with two flywheels and a belt 403, which rotate under the drive of the motor 401 and transmit power.

[0032] Specifically, a connecting rod 404 extends from the inside of the flywheel assembly 402, and a rotating disk 405 is fixedly installed at one end of the connecting rod 404.

[0033] Furthermore, the connecting rod 404 is rotated through the transmission of the flywheel assembly 402, thereby enabling the rotating disk 405 to rotate stably.

[0034] Specifically, a locking block 406 is rotatably connected to the outer wall of the rotating disk 405, and a locking groove 407 is provided on the outer wall of the locking block 406 corresponding to the position of the rotating disk 405.

[0035] Furthermore, the rotating disk 405 engages with the engaging block 406 via the engaging groove 407, preventing jamming during later force transmission.

[0036] Specifically, a rotating locking block 408 is rotatably connected to the outer wall of the locking block 406, and a connecting rod 409 is fixedly installed on the outer wall of the rotating locking block 408. A hopper 410 is fixedly installed at one end of the connecting rod 409.

[0037] Furthermore, the locking block 406, through its rotational connection with the rotating locking block 408, allows the rotating disk 405 to drive the locking block 406 under the rotation of the flywheel assembly 402, which in turn drives the hopper 410 to slide back and forth on the moving frame 1 via the connecting rod 409, thereby screening the accumulated material.

[0038] In use, the mobile frame 1 is equipped with self-locking casters for easy and flexible movement. Under the operation of the motor 401, in conjunction with the transmission of the flywheel assembly 402, belt 403 and connecting rod 404, the rotating disk 405 is rotated. Thus, through the cooperation of the locking block 406, locking groove 407 and rotating locking block 408, the connecting rod 409 drives the hopper 410 to slide back and forth along the feeding chute 2 to screen the internal materials.

[0039] In summary, the operation of motor 401 can trigger connecting rod 409 and move hopper 410 to slide back and forth along the feeding chute 2 of moving frame 1, causing material to slide back and forth and collide, avoiding blockage that would affect material screening, and allowing qualified material to fall off, further improving the fineness of screening and improving screening accuracy.

[0040] The scraping mechanism 5 includes a support arm 501, which is fixedly installed on the top of the movable frame 1. The support arm 501 is connected to a sliding frame 502, and the sliding frame 502 is rotatably connected to an abutment roller 503.

[0041] Furthermore, the contact roller 503 is provided with several rubber protrusions on its exterior, which can be inserted between the pores of the filter screen in the hopper 410 during the screening operation to avoid clogging.

[0042] Specifically, a fixing rod 504 is fixedly installed at the top of the sliding frame 502, and a spring 505 is sleeved on the outside of the fixing rod 504.

[0043] Furthermore, the elastic push of the spring 505 allows the contact roller 503 to fully adhere to the filter screen at the bottom of the hopper 410.

[0044] Specifically, a contact plate 506 is fixedly installed at the bottom of the hopper 410, a support rod 507 is fixedly installed on the outer wall of the contact plate 506, and a rotating ring 508 is rotatably connected to the outer wall of the support rod 507.

[0045] Furthermore, the rotating ring 508 is placed on the connecting plate 3 and can roll along the top surface of the connecting plate 3. Through the support of the connecting plate 3, the hopper 410 can roll through the cooperation of the support rod 507 and the rotating ring 508 to improve the smoothness of the displacement of the hopper 410.

[0046] In use, the spring 505 fixed by the support arm 501 elastically pushes the sliding frame 502, allowing the contact roller 503 to adhere to the filter screen of the hopper 410. The rubber protrusions of the contact roller 503 can abut against the pores of the filter screen, and it is fixed to the top of the sliding frame 502 with the fixing rod 504, which passes through the reserved hole of the support arm 501. This can maintain stability when the spring 505 extends and retracts, and prevent the spring 505 from twisting and affecting the stability of the sliding frame 502. In conjunction with the contact plate 506, the support rod 507 and the rotating ring 508, the smoothness of the displacement of the hopper 410 is further improved.

[0047] In summary, the elastic push of the spring 505 allows the contact roller 503 to slide against the filter screen of the hopper 410. As the hopper 410 slides back and forth, the contact roller 503 inserts into the filter screen holes through the external rubber protrusions to prevent clogging and thus maintain the filtration effect. It also agitates the material to prevent accumulation and ensure proper filtration and screening.
