[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1-3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the vibrating screen for recycled sand production and processing provided by this utility model; Figure 2 for Figure 1 An enlarged structural diagram of part A shown in the figure; Figure 3 for Figure 1 The diagram shows an enlarged view of part B. The vibrating screen for recycled sand production and processing includes: a base plate 1; a screen box 3 movably mounted on the base plate 1; a hydraulic cylinder 2 hinged to the base plate 1, the output rod of which is hinged to the screen box 3; a cover plate 6 hinged to the top of the screen box 3; a cleaning opening 8 on one side of the screen box 3; a blocking mechanism installed on one side of the screen box 3 to block the cleaning opening 8; and a vibrating screening mechanism installed on the inner wall of the screen box 3 for screening the recycled sand. The base plate 1 serves as the fixed base supporting the overall structure of the vibrating screen, and the screen box 3 movably mounted on the base plate 1 is tilted via the hinged hydraulic cylinder 2. Angle adjustment: The output rod of hydraulic cylinder 2 is hinged to screen box 3 to flexibly control the elevation angle of screen box 3 to adapt to the screening requirements of different materials. The cover plate 6 hinged to the top of screen box 3 is used to close screen box 3. The cleaning opening 8 on the side of screen box 3, together with the shielding mechanism, enables quick cleaning of screen accumulation. The vibrating screening mechanism installed on the inner wall of screen box 3 uses high-frequency vibration to classify recycled sand according to particle size and separate impurities. This design optimizes screening efficiency by hydraulically adjusting the screen box inclination angle. The cleaning opening 8 and the shielding mechanism simplify the maintenance process. The vibrating screening mechanism improves the purity and particle size uniformity of recycled sand. The overall structure takes into account both production efficiency and ease of operation.

[0021] The shielding mechanism includes: a side plate 9 fixedly installed on one side of the screen box 3; a horizontal shaft 10 rotatably installed on the side plate 9; a rotating plate 11 fixedly sleeved on the horizontal shaft 10; a baffle 12 fixedly installed on the rotating plate 11; and an opening and closing mechanism installed on one side of the screen box 3. The shielding mechanism is supported by the side plate 9 fixedly installed on one side of the screen box 3. The horizontal shaft 10 rotatably installed on the side plate 9 drives the fixedly sleeved rotating plate 11 to rotate. The baffle 12 fixedly installed on the rotating plate 11 moves synchronously with the rotating plate 11 to open or close the cleaning opening 8. The opening and closing mechanism installed on one side of the screen box 3 drives the horizontal shaft 10 to rotate, thereby controlling the opening and closing state of the baffle 12. This design utilizes the linkage structure of the rotating plate 11 and the baffle 12 to achieve rapid opening and closing of the cleaning opening 8, which facilitates the operator to clean the accumulated material inside the screen box 3. At the same time, when the baffle 12 is closed, it ensures the sealing of the screening process and avoids material leakage. The setting of the opening and closing mechanism further improves the convenience and automation of operation, and significantly improves the maintenance efficiency in the process of recycled sand screening.

[0022] The opening and closing mechanism includes: a servo motor 13 fixedly installed on one side of the screen box 3, the model of the servo motor 13 being MHMF082L1U2M; and two bevel gears 14 fixedly installed on the output shaft of the servo motor 13 and on the horizontal shaft 10, respectively, and meshing with each other. The opening and closing mechanism provides power output through the servo motor 13 fixedly installed on one side of the screen box 3. The two bevel gears 14 fixedly installed on the output shaft of the servo motor 13 and on the horizontal shaft 10 mesh with each other to form a right-angle transmission structure, which efficiently transmits the rotational motion of the servo motor 13 to the horizontal shaft 10, thereby driving the rotating plate 11 and the baffle 12 to achieve opening and closing control.

[0023] The vibrating screening mechanism includes: a support plate 15 fixedly installed on the inner wall of the screen box 3; a sliding rod 16 slidably installed on the support plate 15; a screen plate 17 fixedly installed at the top of the sliding rod 16; a first spring 18 slidably sleeved on the sliding rod 16; a limiting block 19 fixedly installed at the bottom of the sliding rod 16; a vertical plate 20 fixedly installed at the bottom of the screen plate 17; and a vibration motor 21 installed on the vertical plate 20. The vibration motor 21 is a YZO-10-6 model. The vibrating screening mechanism is provided with a stable support foundation by the support plate 15 fixedly installed on the inner wall of the screen box 3. The sliding rod 16 slidably installed on the support plate 15 and the screen plate 17 fixed at its top constitute a reciprocating screening assembly. The first spring 18, fitted onto the sliding rod 16, provides elastic reset for the screen plate 17. The limiting block 19, fixedly installed at the bottom of the sliding rod 16, restricts the sliding stroke to prevent the components from detaching. The vertical plate 20, fixedly installed at the bottom of the screen plate 17, serves as the mounting base for the vibrating motor 21. When the vibrating motor 21 runs, it drives the screen plate 17 to generate high-frequency micro-amplitude vibration. This design, through the buffering effect of the first spring 18, enables the screen plate 17 to form a stable vibration effect under the drive of the vibrating motor 21. The limiting block 19 ensures the safety of movement, and the rigid support of the vertical plate 20 ensures the vibration transmission efficiency. The overall structure enables the recycled sand to be evenly dispersed and efficiently graded on the screen plate 17, significantly improving screening accuracy and output. At the same time, the spring damping design effectively reduces equipment operating noise and wear.

[0024] The screen box 3 has a discharge port 5 on one side, and an inclined plate 4 is fixedly installed on the inner wall of the screen box 3. The discharge port 5 on one side of the screen box 3 and the inclined plate 4 fixedly installed on the inner wall work together. The inclined plate 4 guides the screened recycled sand to slide automatically to the discharge port 5 under the action of gravity, so as to realize the continuous and efficient discharge of materials. This design optimizes the material flow path through the inclined plate 4 to avoid accumulation and blockage. The position and size design of the discharge port 5 ensures the smooth output of recycled sand of different particle sizes.

[0025] The cover plate 6 is equipped with a feeding hopper 7, which is made of stainless steel. The feeding hopper 7 on the cover plate 6 is made of wear-resistant and corrosion-resistant stainless steel, providing a reliable feeding channel for recycled sand raw materials. This design achieves centralized feeding of materials through the funnel structure of the feeding hopper 7, avoiding the scattering of raw materials.

[0026] The screen box 3 is equipped with a locking mechanism, which includes: an L-shaped plate 22 fixedly installed on one side of the screen box 3; a crossbar 23 fixedly installed on the inner wall of the L-shaped plate 22 and fixedly connected to the screen box 3; a second spring 24 and a sliding plate 25 slidably sleeved on the crossbar 23; and a locking plate 26 fixedly installed on the sliding plate 25. The locking mechanism installed on the screen box 3 is supported by the L-shaped plate 22 fixedly installed on one side of the screen box 3. The crossbar 23 fixedly connected between the inner wall of the L-shaped plate 22 and the screen box 3 forms a sliding track. The sliding plate 25 slidably sleeved on the crossbar 23 drives the fixedly installed locking plate 26 to achieve lateral displacement. This design ensures the sealing during screening operations through the locking fit between the locking plate 26 and the cover plate 6. The rigid structure of the L-shaped plate 22 ensures the stability of the locking mechanism. The guiding effect of the crossbar 23 makes the sliding plate 25 move smoothly. The adjustable locking function of the locking plate 26 facilitates quick opening and maintenance and effectively prevents the cover plate 6 from loosening due to vibration.

[0027] The working principle of the vibrating screen for recycled sand production and processing provided by this utility model is as follows:

[0028] The base plate 1 serves as the fixed base for the vibrating screen, supporting the overall structure. The screen box 3, movably mounted on the base plate 1, has its tilt angle adjusted via a hinged hydraulic cylinder 2. The output rod of the hydraulic cylinder 2 is hinged to the screen box 3 to flexibly control its elevation angle to adapt to the screening requirements of different materials. A cover plate 6 hinged to the top of the screen box 3 is used to close it. A cleaning opening 8 on the side of the screen box 3, combined with a shielding mechanism, allows for rapid cleaning of accumulated material on the screen. The vibrating screening mechanism installed on the inner wall of the screen box 3 uses high-frequency vibration to classify the recycled sand by particle size and separate impurities. This design optimizes screening efficiency through hydraulic adjustment of the screen box tilt angle and cleaning openings. 8. The shielding mechanism simplifies the maintenance process, and the vibrating screening mechanism improves the purity and particle size uniformity of the recycled sand. The shielding mechanism provides a support structure through a side plate 9 fixedly installed on one side of the screen box 3. The horizontal shaft 10 installed on the side plate 9 drives the fixedly sleeved rotating plate 11 to rotate. The baffle 12 fixedly installed on the rotating plate 11 moves synchronously with the rotating plate 11 to open or close the cleaning opening 8. The opening and closing mechanism installed on one side of the screen box 3 drives the horizontal shaft 10 to rotate, thereby controlling the opening and closing state of the baffle 12. This design utilizes the linkage structure of the rotating plate 11 and the baffle 12 to achieve rapid opening and closing of the cleaning opening 8. This design facilitates cleaning of accumulated material inside the screen box 3 by operators. Simultaneously, the baffle 12 ensures a tight seal during the screening process when closed, preventing material leakage. The opening and closing mechanism further enhances operational convenience and automation, significantly improving maintenance efficiency during the recycled sand screening process. The opening and closing mechanism is powered by a servo motor 13 fixedly mounted on one side of the screen box 3. Two bevel gears 14, fixedly mounted on the output shaft of the servo motor 13 and the horizontal shaft 10, mesh to form a right-angle transmission structure, efficiently transmitting the rotational motion of the servo motor 13 to the horizontal shaft 10, thereby driving the rotating plate 11 and the baffle 12 to rotate. The opening and closing control is provided by the support plate 15 fixedly installed on the inner wall of the screen box 3. The sliding rod 16 slidably installed on the support plate 15 and the screen plate 17 fixed at its top constitute a reciprocating screening component. The first spring 18 slidably sleeved on the sliding rod 16 provides the screen plate 17 with elastic reset function. The limiting block 19 fixedly installed at the bottom of the sliding rod 16 limits the sliding stroke to prevent the component from falling off. The vertical plate 20 fixedly installed at the bottom of the screen plate 17 serves as the mounting base of the vibration motor 21. When the vibration motor 21 runs, it drives the screen plate 17 to generate high-frequency micro-amplitude vibration.This design utilizes the buffering effect of the first spring 18 to ensure stable vibration of the screen plate 17 under the drive of the vibrating motor 21. The limiting block 19 ensures safe movement, and the rigid support of the vertical plate 20 guarantees efficient vibration transmission. The overall structure allows the recycled sand to be evenly dispersed and efficiently graded on the screen plate 17, significantly improving screening accuracy and output. Simultaneously, the spring damping design effectively reduces equipment operating noise and wear. The discharge port 5 on one side of the screen box 3 works in conjunction with the inclined plate 4 fixedly installed on the inner wall. The inclined structure of the inclined plate 4 guides the screened recycled sand to automatically slide towards the discharge port 5 under gravity, achieving continuous and efficient material discharge. This design optimizes the material flow path through the inclined plate 4 to avoid accumulation and blockage. The position and size design of the discharge port 5 ensures smooth output of recycled sand of different particle sizes. The feeding hopper 7 is installed on the cover plate 6. Made of wear-resistant and corrosion-resistant stainless steel, this design provides a reliable feeding channel for recycled sand raw materials. The funnel structure of the feeding hopper 7 enables centralized material feeding, preventing material spillage. The locking mechanism installed on the screen box 3 is supported by an L-shaped plate 22 fixedly installed on one side of the screen box 3. A crossbar 23, fixedly connected between the inner wall of the L-shaped plate 22 and the screen box 3, forms a sliding track. A sliding plate 25, slidably fitted onto the crossbar 23, drives the fixedly installed locking plate 26 to achieve lateral displacement. This design ensures sealing during screening operations through the locking fit between the locking plate 26 and the cover plate 6. The rigid structure of the L-shaped plate 22 ensures the stability of the locking mechanism, and the guiding effect of the crossbar 23 allows the sliding plate 25 to move smoothly. The adjustable locking function of the locking plate 26 facilitates quick opening and maintenance while effectively preventing the cover plate 6 from loosening due to vibration.
