Description

Technical Field

[0001] The utility model relates to the technical field of cement pipe pile processing, in particular to a crushed stone screening device for cement pipe pile processing. Background Art

[0002] Cement pipe piles are widely used in industries such as construction and railways. Due to their advantages of saving wood and steel, durability and low cost, they are often used in various foundation projects and slope and foundation pit support. Concrete piles are usually made of ordinary reinforced concrete or prestressed concrete. However, when processing cement pipe piles, the crushed stone easily clogs the sieve holes during the screening process, affecting the screening effect and work efficiency.

[0003] According to a publicly disclosed gravel screening device for cement pipe pile processing (publication number: CN217857162U), in the above application, the bottom ends of the U-shaped frame and the guide inclined plate are connected to the top of the bottom plate, the guide inclined plate is located inside the U-shaped frame, the bottom end of the support is connected to the top of the bottom plate, the connecting plate is installed on the upper side of the outer end of the two sets of annular frames, the motor is installed on the top of the connecting plate, the gear is installed at the output end of the motor, and an opening is provided on the connecting plate. The gear engages with the gear ring through the opening, and the gear ring is installed on the outside of the screen barrel.

[0004] However, during actual use of the above-mentioned gravel screening device, gravel of similar size to the sieve holes on the screen barrel may get stuck in the sieve holes. If it is simply rotated, when the stuck force is greater than the gravity of the gravel, the gravel cannot fall off from the sieve holes by itself, which will hinder the passage of other gravel and cause the screening process to become slow. In view of this, we propose a gravel screening device for cement pipe pile processing. Utility Model Content

[0016] Compared with the prior art, the present invention provides a crushed stone screening device for cement pipe pile processing, which has the following beneficial effects:

[0017] 1. The gravel screening device for cement pipe pile processing uses a driving gear, a gear ring, a fixed sleeve, a spring and a sleeve. The rotation of the screen barrel drives the gravel in the screen barrel to move further, so that small gravel can pass through the screen hole and fall onto the inclined plate to be collected. At the same time, the self-rotation of the screen barrel prevents the blockage of the screen hole to a certain extent, thereby maintaining the screening efficiency. The rotation of the rotating rod drives the rotation of the toggle rod, which probes into the screen hole and pokes the gravel blocked in the screen hole back into the screen barrel, thereby preventing gravel of similar size to the screen hole on the screen barrel from being stuck in the screen hole. The fixed sleeve pushes the sleeve to move laterally when the sleeve rotates, and then the spring pushes the sleeve to reset, so that the sleeve can swing back and forth in the horizontal direction, thereby increasing the sweeping range of the toggle rod, thereby increasing the coverage of the toggle rod to the screen hole and keeping the screen hole unobstructed.

[0018] 2. The gravel screening device for cement pipe pile processing has a rotating rod and a cam, and the rotation of the rotating shaft drives the rotating rod and the cam to rotate through the transmission of the second belt. When the cam rotates, it knocks the outer wall of the screen barrel, and the knocking force is further transmitted to the gravel, shaking off the stuck gravel, and further preventing the blockage of the screen hole.

[0024] like Figures 1-4 As shown, the utility model provides a technical solution: a gravel screening device for cement pipe pile processing, comprising a base plate 1, an inner wall of the base plate 1 is fixedly connected to an inclined plate 2, the top end surface of the base plate 1 is fixedly connected to a support leg 3, the top end surface of the support leg 3 is fixedly connected to a bracket 4, the bracket 4 is socketed with a screen barrel 5, a material guide port is provided at the bottom of the screen barrel 5, the material guide port is socketed with a baffle 6, and an anti-blocking device is provided on the top end surface of the base plate 1, the anti-blocking device comprises a motor 7, a rotating shaft 8, a driving gear 9, a gear ring 10, a mounting plate 11, a fixed sleeve 12, a rotating rod 13, a sleeve 14, a spring 15, a belt 16, a rotating rod 17, a belt 2 18, and a cam 19.

[0025] In one embodiment of the present utility model, the top end face of the bracket 4 is fixedly connected to the motor 7, the output end of the motor 7 is fixedly connected to the rotating shaft 8, the side wall of the rotating shaft 8 is fixedly connected to the driving gear 9, the side wall of the screen barrel 5 is fixedly connected to the ring gear 10, the driving gear 9 is meshed with the ring gear 10, and the driving gear 9 rotates to drive the ring gear 10 and the screen barrel 5 to rotate.

[0026] The side wall of the bracket 4 is fixedly connected to the mounting plate 11, and the side wall of the mounting plate 11 is sleeved with a rotating rod 13. The cross section of the rotating rod 13 is hexagonal, and the side wall of the rotating rod 13 is sleeved with a sleeve 14. The outer wall of the sleeve 14 is fixedly connected to the toggle rod, and the side wall of the rotating rod 13 is transmission connected to the rotating shaft 8 through a sleeved belt 16. The side of the mounting plate 11 close to the sleeve 14 is fixedly connected to a fixing sleeve 12, and the end of the fixing sleeve 12 close to the sleeve 14 is inclined, and the end of the sleeve 14 close to the fixing sleeve 12 is inclined. The side wall of the rotating rod 13 is sleeved with a spring 15, one end of the spring 15 abuts against the sleeve 14, and the end of the spring 15 away from the sleeve 14 abuts against the side wall of the mounting plate 11.

[0027] The outer wall of the bracket 4 is fixedly connected to the mounting plate 11, the mounting plate 11 is socketed with the rotating rod 17, the rotating rod 17 is transmission-connected to the rotating shaft 8 through the socketed belt 2 18, the side wall of the rotating rod 17 is fixedly connected to the cam 19, the cam 19 is movably connected to the outer wall of the screen barrel 5, and the cam 19 knocks the outer wall of the screen barrel 5 when it rotates, and the knocking force is further transmitted to the gravel, shaking off the stuck gravel.

[0028] The motor 7 is started, driving the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the driving gear 9 to rotate, and further drives the ring gear 10 and the screen barrel 5 to rotate. The rotation of the screen barrel 5 drives the gravel in the screen barrel 5 to further move, so that small gravel can pass through the screen holes and fall onto the inclined plate 2 to be collected. At the same time, the self-rotation of the screen barrel 5 prevents the blockage of the screen holes to a certain extent, thereby maintaining the screening efficiency.

[0029] The rotation of the rotating shaft 8 drives the rotating rod 13 to rotate through the transmission of the belt 16, and the rotation of the rotating rod 13 drives the toggle rod to rotate. The toggle rod probes into the sieve hole and pokes the gravel blocked in the sieve hole back into the sieve barrel 5 to avoid gravel with a size similar to the sieve hole on the sieve barrel 5 from being stuck in the sieve hole. At the same time, since the end of the fixed sleeve 12 close to the sleeve 14 is inclined, the end of the sleeve 14 close to the fixed sleeve 12 is inclined. When the sleeve 14 rotates, the fixed sleeve 12 pushes the sleeve 14 to move laterally, and then the spring 15 pushes the sleeve 14 to reset, so that the sleeve 14 can swing back and forth in the horizontal direction, thereby increasing the sweeping range of the toggle rod, and then increasing the coverage of the sieve hole by the toggle rod, keeping the sieve hole unobstructed.

[0030] In addition, the rotation of the rotating shaft 8 drives the rotating rod 17 and the cam 19 to rotate through the transmission of the belt 2 18. When the cam 19 rotates, it knocks on the outer wall of the screen barrel 5. The knocking force is further transmitted to the gravel, shaking off the stuck gravel, further preventing the blockage of the screen holes. The combination of multiple anti-blocking mechanisms improves the screening efficiency, reduces the maintenance frequency and downtime of the equipment, and ensures the continuous and efficient operation of the equipment.

[0031] In the utility model, when in use, gravel is put into the sieve barrel 5 from the top of the sieve barrel 5, and the sieve barrel 5 rotates to prevent the sieve holes from being blocked to a certain extent. The toggle rod rotates, and the toggle rod probes into the sieve holes, and the gravel blocked in the sieve holes is re-poked into the sieve barrel 5. The sleeve 14 swings back and forth in the horizontal direction to increase the coverage of the sieve holes by the toggle rod. When the cam 19 rotates, it knocks on the outer wall of the sieve barrel 5, and the knocking force is further transmitted to the gravel, and the stuck gravel is shaken off.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
