Description

Technical Field

[0001] This utility model relates to the field of sand and gravel screening technology, specifically a roller cage type high-efficiency sand screening device. Background Technology

[0002] The screening process separates sand and gravel into particles of different sizes using screens, ensuring that the particle size distribution of the sand and gravel meets specific requirements. This is crucial for controlling the quality of manufactured sand, as particle size and gradation requirements better guarantee that the produced manufactured sand meets the grading quality standards and regulations defined in the specifications.

[0003] The existing Chinese utility model patent with publication number CN2868453Y discloses a novel sand screening machine. It mainly consists of a frame, roller support, vibrating drum, reducer, and motor. The front end of the vibrating drum is supported by the roller, and the rear end connects to the reducer and motor. The entire machine is mounted on the frame, and the motor drives the reducer to rotate the vibrating drum for screening. This novel sand screening machine is mainly used for screening sand used in construction sites and small-to-medium-sized precast building component factories. It can also be used for screening coal powder in honeycomb briquette processing, screening grain before storage or processing, and screening molding sand in foundry workshops in the machinery manufacturing industry. This sand screening machine solves the problems currently faced by these industries, such as sand, coal powder, and grain not meeting usage requirements without screening, high labor intensity, low efficiency, and unreliable quality in manual screening. It offers significant economic and social benefits and has value for widespread application.

[0004] In order to improve the screening effect, the existing roller cage screening device has a long roller cage. Fine material will be discharged from below within the projection range of the roller cage. The large range makes it very inconvenient to collect fine material. At the same time, in order to keep the roller cage running smoothly, the position of the roller cage is generally restricted by bearings. During use, material may get stuck inside the roller cage.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a roller-type high-efficiency sand screening device includes: a support frame 1, a support pipe 11 fixedly installed above the support frame 1, a connecting bearing 12 fixedly installed inside the support pipe 11, a connecting ring 13 movably installed at the front end of the support pipe 11, an end plate 14 movably installed at the rear end of the support pipe 11, a limiting ring 15 movably installed inside the support pipe 11, a baffle 16 fixedly installed inside the limiting ring 15, a feed pipe 17 movably installed on the rear side of the end plate 14, a limiting frame 18 fixedly installed below the feed pipe 17, a sliding groove 19 movably installed at the front end of the connecting ring 13, and the connecting ring... A toothed ring 110 is fixedly installed on the outer side of the support tube 11, a connecting frame 111 is fixedly installed on the outer side of the support tube 11, a drive motor 112 is fixedly installed inside the connecting frame 111, a gear 113 is fixedly installed on the outer side of the shaft of the drive motor 112, a stop bar 114 is fixedly installed between the limiting rings 15, a receiving groove 115 is fixedly installed below the support tube 11, a gantry frame 116 is fixedly installed above the support frame 1, a limiting post 117 is inserted above the gantry frame 116, a spring 118 is inserted on the outer side of the limiting post 117, and a plate 119 is fixedly installed at the bottom end of the limiting post 117.

[0027] The support frame 1 is symmetrically installed on both the front and rear sides of the support tube 11 with the center of the support tube 11 as the reference. The connecting ring 13, end plate 14, and limiting ring 15 are rotatably connected to the support tube 11 through the connecting bearing 12. The limiting ring 15 is installed equidistantly inside the support tube 11. The end plate 14 has an opening structure at its center that fits into the feed pipe 17. The end plate 14 and the feed pipe 17 are rotatably connected. The baffle 16 is spiral-shaped and is installed in an "X" shape inside the limiting ring 15 with the center of the limiting ring 15 as the reference. The slide groove 19 is rotatably connected to the connecting ring 13 through the connecting bearing 12. The drive motor 112 is connected to the connecting ring 13 through the connecting bearing 12. The connecting frame 111 is mirror-symmetrically installed on the left and right sides of the front end of the support tube 11. The gear 113 meshes with the gear ring 110. The stop rod 114 is installed in a ring between the limiting rings 15 with the center of the support tube 11 as the reference. The limiting rings 15 and the connecting ring 13 are connected, and the limiting rings 15 and the end plate 14 are connected. The front and rear ends of the gantry frame 116 are fixedly connected to the top of the front and rear supporting frames 1 respectively. The limiting post 117 and the gantry frame 116 form a sliding connection. The spring 118 is located between the gantry frame 116 and the insert plate 119. The bottom surface of the insert plate 119 is provided with a triangular protrusion structure, and the protrusion structure of the insert plate 119 is fitted between the stop rods 114.

[0028] Specifically, the stop rod 114 is installed in a ring shape between the limiting rings 15 and the connecting ring 13, and between the limiting ring 15 and the end plate 14, with the supporting pipe 11 as the reference. The connecting ring 13, the limiting ring 15, the end plate 14, and the stop rod 114 form a tubular structure and are rotatably connected to the supporting pipe 11 through the connecting bearing 12. The upper and lower sides of the supporting pipe 11 are provided with opening structures. The supporting pipe 11 is raised by the support frame 1. The gear ring 110 is fixed to the outside of the connecting ring 13. The gear 113 is driven to rotate by the two drive motors 112, thereby driving the connecting ring 13 to rotate through the gear ring 110. The baffle 16 is spiral and is fixedly connected to the limiting ring 15. When the limiting ring 15 rotates, it will drive the baffle 16 to rotate. When the baffle 16 rotates, it can drive the material to rotate around the center of the supporting pipe 11 and move forward at the same time. After the baffle 16 drives the material to rotate more than 90 degrees, Material slides down from above the baffle 16, returning to the space between the baffles 16 to improve screening efficiency. Material that cannot pass between the baffles 114 will move forward under the influence of the baffles 16 and be discharged from the chute 19. Material that can pass through the baffles 16 will fall downward into the receiving trough 115. The bottom surface of the receiving trough 115 is a sloping structure with a higher front and lower back. Material will be discharged from the rear end under the guidance of the receiving trough 115. The bottom surface of the insert plate 119 is provided with a triangular protrusion structure, and the protrusion structure of the insert plate 119 is fitted between the baffles 114. When the baffles 114 rotates, the protrusion structure on the bottom surface of the insert plate 119 will lift the insert plate 119, causing the insert plate 119 to compress the spring 118. Then, as the baffles 114 rotates, the spring 118 will drive the insert plate 119 to reset. The force of the insert plate 119 during reset will squeeze out the material stuck between the baffles 114, preventing the material from getting stuck between the baffles 114.

[0029] In use, the support pipe 11 has openings on its upper and lower sides. The support pipe 11 is raised by the support frame 1, and the receiving groove 115 is fixedly installed below the support pipe 11. The support pipe 11 is connected to the receiving groove 115 through the openings below. After the material enters the support pipe 11, it will stay above the baffle 114. Material smaller than the distance between the baffles 114 will enter the receiving groove 115 through the openings below the support pipe 11. The bottom surface of the receiving groove 115 is a sloping structure with a higher front and a lower back. The material will be discharged from the rear end under the guidance of the receiving groove 115, which facilitates the centralized collection of fine materials. The insert plate 119 is installed below the gantry frame 116 via a limiting post 117. The limiting post 117 can restrict the movement direction of the insert plate 119. The bottom surface of the insert plate 119 is provided with a triangular protrusion structure, and the protrusion structure of the insert plate 119 is fitted between the stop rods 114. When the stop rods 114 rotate, they will push the insert plate 119 up through the protrusion structure on the bottom surface of the insert plate 119, causing the insert plate 119 to compress the spring 118. Then, as the stop rods 114 rotate, the spring 118 will drive the insert plate 119 to reset. The force of the insert plate 119 when resetting will squeeze out the material stuck between the stop rods 114, thus preventing the material from getting stuck between the stop rods 114.
