Description

Technical Field

[0001] This utility model relates to the field of quartz sand technology, specifically to a feeding and unblocking device for quartz sand production. Background Technology

[0002] Quartz sand is an industrial raw material made from natural quartz ore through crushing, screening, and purification processes; it is widely used in building materials, electronics, chemicals and other fields.

[0003] Raw materials such as natural quartz ore are first crushed by a crushing device to obtain small-sized materials for subsequent production. However, during the process of quartz sand entering the crushing device, the quartz sand will be squeezed against the inner wall of the feeding channel. When the quartz sand is squeezed into equilibrium in the feeding channel, it will cause blockage in the feeding channel, resulting in poor material discharge. This requires manual unblocking and affects production efficiency. Summary of the Invention

[0004] This invention addresses the problem of easy blockage of quartz sand raw materials in the feeding channel by providing a feeding and unblocking device for quartz sand production. This device can prevent quartz sand from reaching a balance with the inner wall of the feeding channel, thus avoiding blockage.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A feeding and unblocking device for quartz sand production includes a feeding pipe with a feeding hopper at its upper end. The feeding pipe has sliding holes at both ends of its peripheral wall. Two movable plates are symmetrically arranged on the left and right sides of the feeding pipe, each plate being an arc-shaped plate with opposing protrusions. A crossbar is connected to the opposing sides of the two movable plates. The free end of each crossbar passes through a sliding hole on the same side. Bearing plates are fixedly fitted onto the outer walls of the feeding pipe above and below the sliding holes. Rotating rods are rotatably connected between the left and right sides of the opposing surfaces of the two bearing plates. The lower part of the left rotating rod is threaded to the left crossbar via an external thread (Thread 1), and the lower part of the right rotating rod is threaded to the right crossbar via an external thread (Thread 2). The external threads (Thread 1 and Thread 2) rotate in opposite directions. A driving component is provided on the feeding pipe to drive the two rotating rods to rotate counterclockwise or clockwise in the same direction.

[0007] Furthermore, the adjacent vertical sides of the two movable plates are in sliding contact, and the opposite sides of the two movable plates are in sliding contact with the inner wall of the feed pipe. The opposing surfaces of the two movable plates are evenly distributed with protrusions.

[0008] Furthermore, the front and rear sides of each crossbar slide in contact with the front and rear sides of the corresponding sliding hole.

[0009] Furthermore, both of the rotating rods have helical grooves on the upper part of their peripheral walls; the helical grooves are both right-handed.

[0010] Furthermore, the driving component includes a movable ring and a hydraulic cylinder. The movable ring is movably sleeved on the feed pipe between the sliding hole and the upper support plate. The left and right parts of the movable ring are slidably sleeved on the outside of the rotating rod on the same side through through holes. Each through hole has a driving rod extending into the spiral groove on the same side on its inner wall. The top surface of the lower support plate is fixed with a hydraulic cylinder, and the piston end of the hydraulic cylinder is connected to the movable ring with its upward facing direction.

[0011] Furthermore, the first external thread is a right-hand thread, the second external thread is a left-hand thread, and the height of both movable plates is less than the height of the feed pipe.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] After the quartz sand raw material is fed into the feed pipe, the driving component drives two rotating rods to rotate counterclockwise or clockwise in the same direction. The two rotating rods drive the corresponding movable plates to move in opposite directions up and down. Therefore, it can prevent the quartz sand raw material from forming a balance between the two movable plates, thereby preventing the quartz sand raw material from blocking between the two movable plates and allowing the quartz sand raw material to enter the crushing device smoothly.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figs. 1-3As shown, a feeding and unblocking device for quartz sand production includes a feeding pipe 1, which is a circular pipe with a feeding hopper 2 at its upper end. The lower left and right ends of the peripheral wall of the feeding pipe 1 are provided with sliding holes 3, which are elongated holes arranged along the height direction of the feeding pipe 1. Symmetrically arranged movable plates 4 are provided on the left and right sides of the feeding pipe 1. The two movable plates 4 are arc-shaped plates with opposing protrusions. Crossbars 5 are connected to the opposing sides of the two movable plates 4. The crossbars 5 are rectangular rods, and the free end of each crossbar 5 passes through the sliding hole 3 on the same side. A bearing plate 6 is fixedly fitted on the outer wall of the feed pipe 1 on both the upper and lower sides of the sliding hole 3. The bearing plate 6 is a circular plate. Rotating rods 7 are rotatably connected between the left and right sides of the two bearing plates 6. The rotating rods 7 are round rods. The lower part of the left rotating rod 7 is threaded to the left crossbar 5 via external thread 8. The lower part of the right rotating rod 7 is threaded to the right crossbar 5 via external thread 9. The external threads 8 and 9 have opposite directions of rotation. The feed pipe 1 is equipped with a driving component, which is used to drive the two rotating rods 7 to rotate counterclockwise or clockwise in the same direction.

[0020] The adjacent vertical sides of the two movable plates 4 are in sliding contact, and the opposite sides of the two movable plates 4 are in sliding contact with the inner wall of the feed pipe 1. The two movable plates 4 are evenly distributed with protrusions 10 on their opposite surfaces, and the protrusions 10 are hemispherical.

[0021] The front and rear sides of each crossbar 5 slide in contact with the front and rear sides of the corresponding sliding hole 3.

[0022] Both rotating rods 7 have spiral grooves 11 on their upper peripheral walls; the upper end of each spiral groove 11 passes through the upper end of the rotating rod 7, and the spiral grooves 11 are all right-handed.

[0023] The driving component includes a movable ring 12 and a hydraulic cylinder 13. The movable ring 12 is movably sleeved on the feed pipe 1 between the sliding hole 3 and the upper support plate 6. The movable ring 12 is a circular body with its inner ring sliding in contact with the outer wall of the feed pipe 1. The left and right parts of the movable ring 12 are slidably sleeved on the outside of the rotating rod 7 on the same side through through holes 14. The through holes 14 are circular holes with a diameter matching the diameter of the rotating rod 7 on the same side. Each through hole 14 has a driving rod 15 extending into the spiral groove 11 on the same side on its inner wall. The driving rod 15 is a circular rod that slides in contact with the spiral groove 11. The hydraulic cylinder 13 is fixed on the top surface of the lower support plate 6. The piston end of the hydraulic cylinder 13 is connected to the movable ring 12 with its piston facing upward.

[0024] The external thread 8 is a right-hand thread, and the external thread 9 is a left-hand thread. The heights of the two movable plates 4 are both less than the height of the feed pipe 1.

[0025] When the movable ring 12 moves downward from contact with the upper bearing plate 6 to the lower end of each drive rod 15 located in the spiral groove 11, the left crossbar 5 moves downward to the lower end near the left sliding hole 3, the lower end of the left movable plate 4 is close to the lower end of the feed pipe 1 and the upper end is higher than the upper end of the left sliding hole 3, and the right crossbar 5 moves upward to the upper end near the right sliding hole 3, the upper end of the right movable plate 4 is close to the upper end of the feed pipe 1 and the lower end is lower than the lower end of the right sliding hole 3. The purpose is to prevent material from leaking through the sliding hole 3.

[0026] In use, the lower end of the feed pipe 1 of this utility model is connected to the feed inlet of the crushing device. The feed pipe 1 is vertically arranged, and the quartz sand raw material is fed into the feed pipe 1 through the feed hopper 2. The hydraulic cylinder 13 drives the movable ring 12 to move up and down reciprocally. When the movable plate 4 moves downward, the two drive rods 15 press against the spiral groove 11. Since the spiral groove 11 is right-handed, the two rotating rods 7 rotate counterclockwise in the same direction (the counterclockwise rotation of the rotating rods 7 is...). Fig. 3 (From a top-down perspective), since the external thread 8 is threaded to the left crossbar 5, and the left crossbar 5 is confined within the left sliding hole 3, it can only move up and down. Therefore, when the left drive rod 15 rotates counterclockwise, the left crossbar 5 drives the left movable plate 4 to move downward. Similarly, the external thread 9 on the right rotating rod 7 is threaded to the right crossbar 5. The external thread 9 and external thread 8 have opposite directions of rotation, and the right crossbar 5 drives the right movable plate 4 to move upward. When the movable ring 12 moves upward, the two rotating rods 7 rotate clockwise in the same direction (the clockwise rotation of the rotating rod 7 is...). Fig. 3 (From a top-down perspective), the horizontal bar 5 on the left moves the movable plate 4 on the left upward, and the horizontal bar 5 on the right moves the movable plate 4 on the right downward. The two movable plates 4 move in opposite directions, which can prevent the quartz sand raw material from forming a balance between the two movable plates 4, thereby preventing the quartz sand raw material from blocking between the two movable plates 4. The quartz sand raw material in the feed pipe 1 smoothly enters the crushing device through the lower opening of the feed pipe 1.
