Description

Technical Field

[0001] This utility model relates to the field of pipe pile production technology, specifically a pipe pile production feeding machine. Background Technology

[0002] Pipe piles are hollow cylindrical precast concrete components, mainly used for foundation treatment in construction, bridge and other projects. They enhance foundation stability by transferring loads to deeper soil layers. In the production of pipe piles, concrete raw materials need to be put into a mold containing a steel cage, and then the mold needs to be closed to realize the production of pipe piles.

[0003] In the existing technology, when using a feeder to feed the mold used to produce pipe piles, viscous materials such as concrete tend to accumulate and clump at the bottom of the feeder's feeding bin, requiring frequent manual unblocking, which reduces production efficiency. Furthermore, after feeding the material into the mold, manual tools are needed to level and tidy the surface of the raw material fed into the mold, which is troublesome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding machine for pipe pile production to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A pipe pile production feeding machine includes a frame for feeding material into the lower mold of the pipe pile. A feeding bin is movably installed inside the frame. Reciprocating screws are rotatably connected to both sides of the frame. Screw sleeves are fitted around the two reciprocating screws. An anti-blocking mechanism is provided inside the feeding bin near the bottom. Connecting rods are fixedly connected to the outer walls of the two screw sleeves. A scraping mechanism is provided between the ends of the two connecting rods away from the screw sleeves.

[0007] The anti-blocking mechanism includes a lever and two lever plates. The two lever plates are rotatably connected to the inside of the feeding bin and are located near the bottom via shafts. The lever is rotatably connected to the inside of the feeding bin and is located between the two lever plates. A crossbar is fixedly connected to the outer wall of each of the two lever plates.

[0008] Preferably, both lead screw sleeves are slidably connected inside the frame, and both lead screw sleeves are fixedly connected to the feeding bin. Two motors are installed on the outer wall of the frame, and the output ends of the two motors are respectively connected to one end of the two reciprocating lead screws.

[0009] The crossbar is fitted with a slider and two support springs. One end of the slider is connected to a telescopic link via a hinge, and the end of the telescopic link away from the slider is connected to the inner wall of the feeding bin via a hinge. The telescopic link is fitted with a support spring.

[0010] Preferably, the anti-blocking mechanism further includes two rotating shafts, both of which are rotatably connected inside the feeding hopper, and both of which are fixedly connected to gears on the outside.

[0011] Preferably, belts are fitted between the actuating lever and the other two rotating shafts, and L-shaped mounting plates are fixedly installed on the outer wall of the feeding bin. A second motor is installed on the outer wall of the L-shaped mounting plate, and the output end of the second motor is connected to one end of the actuating lever.

[0012] Preferably, the scraping mechanism includes a scraper, which is movably installed below the frame. Arc-shaped frames are fixedly installed on both sides of the outer wall of the scraper, and one of the arc-shaped frames is fixedly connected to two connecting rods. Sliding rods are slidably connected inside both arc-shaped frames.

[0013] Preferably, a connecting rod is fixedly connected between one end of the two sliding rods, a fixing rod is inserted inside the connecting rod, a fixing hole is opened on the outer wall of the scraper and located directly below the fixing rod, and the fixing hole fits with the fixing rod, and a limit spring is installed between the upper end of the fixing rod and the inner top end of the connecting rod.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, the motor on the L-shaped mounting plate drives the actuating rod to rotate, which can agitate the falling raw materials and prevent them from clogging the feeding port. At the same time, the two belts and the rotating shaft can drive the gear to rotate, which drives the actuating plate to swing continuously at the bottom of the feeding hopper, breaking up the accumulated materials and further preventing material accumulation and blockage.

[0017] 2. In this utility model, when the feeding bin moves back and forth to feed the material into the lower mold of the pipe pile, the scraping mechanism moves back and forth with the feeding bin, so that the scraper continuously scrapes the surface of the input raw material.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] A type of pipe pile production feeding machine, such as Figures 1-8 As shown, the device includes a frame 1 for feeding material into the lower mold 2 of the pipe pile. A feeding bin 3 is movably installed inside the frame 1. Reciprocating screws 4 are rotatably connected to both sides inside the frame 1. Screw sleeves 5 are fitted on the outside of both reciprocating screws 4. An anti-blocking mechanism is provided inside the feeding bin 3 near the bottom. Connecting rods 7 are fixedly connected to the outer walls of both screw sleeves 5. A scraping mechanism is provided between the ends of the two connecting rods 7 away from the screw sleeves 5. The anti-blocking mechanism includes a toggle rod 12 and two toggle plates 17. Both toggle plates 17 are rotatably connected to the inside of the feeding bin 3 near the bottom via shafts. The toggle rod 12 is rotatably connected to the inside of the feeding bin 3 and located between the two toggle plates 17. Crossbars 16 are fixedly connected to the outer walls of both toggle plates 17.

[0032] Both lead screw sleeves 5 are slidably connected inside the frame 1, and both lead screw sleeves 5 are fixedly connected to the feeding bin 3. Two motors are installed on the outer wall of the frame 1, and the output ends of the two motors are respectively connected to one end of the two reciprocating lead screws 4. A slider 24 and two support springs are sleeved on the outside of the crossbar 16. One end of the slider 24 is connected to a telescopic connecting rod 15 through a hinge, and the end of the telescopic connecting rod 15 away from the slider 24 is connected to the inner wall of the feeding bin 3 through a hinge. A support spring is sleeved on the outside of the telescopic connecting rod 15. The telescopic connecting rod 15 and the support spring 2 work together to support the actuating plate 17. When the actuating plate 17 vibrates, the telescopic connecting rod 15 can continuously extend and retract with it. The support spring 2 is continuously compressed and stretched accordingly. At the same time, both ends of the telescopic connecting rod 15 can rotate accordingly, and the slider 24 can also slide along the outside of the crossbar 16. The support spring 1 is continuously compressed and stretched accordingly. All of these can play the role of supporting, limiting and resetting 17.

[0033] The anti-blocking mechanism also includes two rotating shafts 13, both of which are rotatably connected inside the feeding bin 3. Gears 14 are fixedly connected to the outside of both rotating shafts 13. When the gears 14 rotate, the ends of each tooth on them continuously contact the bottom surface of the actuating plate 17, which can drive the actuating plate 17 to vibrate continuously, breaking up the raw materials and preventing material accumulation.

[0034] A belt 18 is fitted between the actuating lever 12 and the other two rotating shafts 13. An L-shaped mounting plate 19 is fixedly installed on the outer wall of the feeding bin 3. A second motor is installed on the outer wall of the L-shaped mounting plate 19, and the output end of the second motor is connected to one end of the actuating lever 12. The second motor drives the actuating lever 12 to rotate, which can agitate the falling raw materials and prevent them from being blocked at the feeding port. At the same time, the two belts 18 drive the two rotating shafts 13 to rotate.

[0035] When in use, the raw materials are fed into the lower mold 2 of the pipe pile through the feeding bin 3. During feeding, the reciprocating screw 4 is rotated by the motor 1, so that the screw sleeve 5 slides along the inside of the frame 1, thereby driving the feeding bin 3 to move back and forth inside the frame 1, and evenly feeding the raw materials into the lower mold 2 of the pipe pile.

[0036] While feeding, the motor on the L-shaped mounting plate 19 drives the lever 12 to rotate, which can agitate the falling raw materials and prevent them from clogging the feeding port. At the same time, the two belts 18 drive the two rotating shafts 13 to rotate, which can drive the gear 14 to rotate and drive the lever 17 to swing continuously at the bottom of the feeding bin 3, breaking up the accumulated materials and further preventing material accumulation and blockage.

[0037] The scraping mechanism includes a scraper 6, which is movably installed below the frame 1. Arc-shaped frames 8 are fixedly installed on the outer wall of the scraper 6 near both sides, and one of the arc-shaped frames 8 is fixedly connected to two connecting rods 10. Sliding rods 9 are slidably connected inside the two arc-shaped frames 8.

[0038] A connecting rod 10 is fixedly connected between one end of the two sliding rods 9. A fixing rod 11 is inserted inside the connecting rod 10. A fixing hole is opened on the outer wall of the scraper 6 and located directly below the fixing rod 11. The fixing hole fits into the fixing rod 11. A limit spring is installed between the upper end of the fixing rod 11 and the inner top end of the connecting rod 10. Through the elastic force of the limit spring, the fixing rod 11 can be driven to insert into the fixing hole to fix the position of the two sliding rods 9.

[0039] Both sliding rods 9 are fixedly connected to a connecting frame 23 at one end. A U-shaped frame 20 is movably installed inside the connecting frame 23. A prismatic plate 21 is movably installed inside the scraper 6. Both connecting frames 23 are fixedly connected to the prismatic plate 21 at one end. A pin 22 is inserted into the outer wall of the connecting frame 23. A fixing groove is opened on the outer wall of the U-shaped frame 20. The fixing groove fits with the pin 22. One end of the pin 22 passes through the connecting frame 23 and is inserted into the fixing groove, which can fix the position of the U-shaped frame 20.

[0040] Specifically, when the feeding bin 3 finishes feeding the material into the lower mold 2 of the pipe pile by moving back and forth, the scraping mechanism connected by two connecting rods 7 moves back and forth with the feeding bin 3, so that the scraper 6 continuously scrapes the surface of the input raw material. This not only removes excess raw material, but also makes the surface smoother after feeding, which is beneficial to the subsequent pipe pile production operation. It realizes automatic leveling of raw materials without manual processing, saving time and effort.

[0041] When scraping is complete and the scraper 6 needs to be cleaned, the pin 22 can be pulled out to release the fixation of the U-shaped frame 20. Then, the U-shaped frame 20 is moved downward along the inside of the connecting frame 23, causing the prismatic plate 21 to move downward, so that the edge of the prismatic plate 21 is aligned with the outer wall of the scraper 6. The position of the prismatic plate 21 is then fixed by the pin 22. The fixing rod 11 is then moved upward and removed from the fixing hole to release the fixation of the sliding rod 9. At this time, the sliding rod 9 can be moved along the inside of the two arc-shaped frames 8 to move the connecting frame 23, thereby moving the prismatic plate 21 along the inner wall of the scraper 6 to scrape off the raw material adhering to the inner wall of the scraper 6, making it easier for workers to clean the scraper 6.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
