Description

Technical Field

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

[0002] Pipe piles are foundation engineering components made of steel pipes and concrete. Concrete refers to a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. A concrete discharge device is a piece of equipment used to transport concrete from a mixer to a construction site. This process is usually called "discharge". The concrete is discharged from the container of the mixer to supply the construction site or other places where concrete is needed.

[0003] According to Chinese utility model application number 202323608876.8, a concrete feeding device was proposed. The utility model describes that "by setting an extension bucket, the length can be adjusted as needed, increasing the adaptability of the feeding device. In addition, by setting a rotating plate, the impact of concrete feeding can be reduced, avoiding splashing during concrete feeding and reducing waste."

[0004] In this concrete feeding device, concrete is discharged from the discharge port of the mixing hopper and falls onto the top of the rotating plate. The rotating plate compresses the torsion spring, reducing the impact of concrete feeding. However, during the feeding process, concrete may adhere to the inner wall of the discharge port of the mixing hopper, or even cause blockage of the discharge port, affecting the feeding effect. It is necessary to clean or unclog the discharge port of the mixing hopper in a timely manner. Therefore, a concrete feeding device for pipe pile production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete feeding device for pipe pile production, which has advantages such as good feeding effect. It solves the problem that concrete may adhere to the inner wall of the discharge port of the mixing hopper during the feeding process, or even cause blockage of the discharge port of the mixing hopper, thus affecting the feeding effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete feeding device for pipe pile production, comprising a mixing tank, a support leg fixedly installed at the bottom of the mixing tank, a feeding pipe connected to the bottom of the mixing tank, a feeding valve fixedly installed on the outside of the feeding pipe, a lifting mechanism provided on the support leg, and a cleaning mechanism provided on the lifting mechanism;

[0007] The lifting mechanism includes a mounting plate, which is fixedly connected to the outside of the support leg. An electric push rod is fixedly mounted on the top of the mounting plate. The output end of the electric push rod passes through the mounting plate and is fixedly mounted on the lifting plate. A stop block is fixedly mounted on the outside of the lifting plate. A baffle is fixedly mounted on the outside of the stop block. A guide plate is fixedly mounted on the bottom of the baffle.

[0008] The cleaning mechanism includes a connecting plate, which is fixedly connected to the inside of the baffle. A cleaning motor is fixedly installed on the top of the connecting plate. The output end of the cleaning motor passes through the baffle and is fixedly installed with a rotating shaft. A stirring rod is fixedly installed on the outside of the rotating shaft. A scraper that fits against the inner wall of the feed pipe is provided on the stirring rod.

[0009] Furthermore, the top of the baffle is arc-shaped, and the top of the guide plate is sloped.

[0010] Furthermore, a fixing plate is fixedly installed on the side of the stirring rod away from the rotating shaft, and the fixing plate is threadedly connected to the scraper by bolts.

[0011] Furthermore, a collection bucket is placed below the mixing tank, and the top area of ​​the collection bucket is larger than the bottom area of ​​the guide plate.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This concrete feeding device for pipe pile production consists of a mixing tank, support legs, a feeding pipe, a lifting mechanism, and a cleaning mechanism. The feeding valve on the outside of the feeding pipe is opened, and the concrete, after being mixed in the mixing tank, is discharged along the feeding pipe. The lifting mechanism disperses the concrete, reducing the impact force of the feeding and minimizing concrete waste due to splashing. The cleaning mechanism mixes the concrete inside the feeding pipe and cleans the inner wall of the pipe, preventing concrete from adhering to the inner wall during feeding, reducing the occurrence of blockages, and improving the feeding efficiency.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 In this embodiment, a concrete feeding device for pipe pile production includes a mixing tank 1. Four support legs 2 are fixedly installed at the bottom of the mixing tank 1. The four support legs 2 are distributed in a ring at equal intervals. A feeding pipe 3 is connected to the bottom of the mixing tank 1. A feeding valve is fixedly installed on the outside of the feeding pipe 3. A lifting mechanism 4 is provided on the support legs 2. A cleaning mechanism 5 is provided on the lifting mechanism 4. A collection bucket 6 is placed below the mixing tank 1.

[0020] Specifically, the discharge valve on the outside of the discharge pipe 3 is opened, and the concrete, after being mixed by the mixing tank 1, is discharged along the discharge pipe 3. The lifting mechanism 4 disperses the concrete, reducing the impact force of the discharge and minimizing concrete waste due to splashing. The concrete is collected inside the collection bucket 6. The cleaning mechanism 5 mixes the concrete inside the discharge pipe 3 and cleans the inner wall of the discharge pipe 3, making it less likely for the concrete to adhere to the inner wall of the discharge pipe 3 during the discharge process, reducing the occurrence of blockage in the discharge pipe 3 and improving the discharge efficiency.

[0021] In this embodiment, the mixing tank 1 includes an outer shell, with a feed pipe connected to the top of the outer shell. A feed valve is fixedly installed on the outside of the feed pipe. A stirring motor is installed inside the top of the outer shell. The output end of the stirring motor passes through the outer shell and is fixedly installed with a stirring rod. Multiple stirring blades are fixedly installed on the outside of the stirring rod. The multiple stirring blades are distributed in a ring at equal intervals.

[0022] Specifically, open the feed valve, pour the concrete raw materials into the feed pipe, turn on the mixing motor, and the mixing motor drives the mixing rod and mixing blades to rotate, and the mixing blades mix the concrete raw materials.

[0023] In this embodiment, the lifting mechanism 4 includes two mounting plates 41, which are distributed and fixedly connected to the outside of the two support legs 2. An electric push rod 42 is fixedly installed on the top of each of the two mounting plates 41. The output ends of the two electric push rods 42 pass through the mounting plates 41 and are fixedly installed with lifting plates 43. A stop block 44 is fixedly installed on the outside of each of the two lifting plates 43. A baffle 45 is fixedly installed at the bottom of the two stop blocks 44. The top of the baffle 45 is arc-shaped, and a guide plate 46 is fixedly installed at the bottom of the baffle 45. The top of the guide plate 46 is inclined, and the top area of ​​the collection bucket 6 is larger than the bottom area of ​​the guide plate 46.

[0024] Specifically, by simultaneously activating two electric push rods 42, the two electric push rods 42 drive two lifting plates 43, two stop blocks 44, baffles 45 and guide plates 46 to move upward or downward. The concrete flows downward along the baffles 45 and guide plates 46, dispersing the concrete, reducing the impact force of the discharge, and reducing the amount of concrete wasted due to splashing.

[0025] In this embodiment, the cleaning mechanism 5 includes a connecting plate 51, which is fixedly connected to the inside of the baffle 45. The connecting plate 51 is cross-shaped, and a cleaning motor 52 is fixedly installed on the top of the connecting plate 51. The output end of the cleaning motor 52 passes through the baffle 45 and is fixedly installed with a rotating shaft 53. Multiple stirring rods 54 are fixedly installed on the outside of the rotating shaft 53. The multiple stirring rods 54 are evenly distributed in a ring. A scraper 55 is provided on the stirring rod 54 and fits against the inner wall of the feed pipe 3. A fixing plate is fixedly installed on the side of the stirring rod 54 away from the rotating shaft 53. The fixing plate is threadedly connected to the scraper 55 by bolts.

[0026] Specifically, by turning on the cleaning motor 52, the cleaning motor 52 drives the rotating shaft 53, the stirring rod 54 and the scraper 55 to rotate, and the scraper 55 cleans the inner wall of the discharge pipe 3.

[0027] The working principle of the above embodiments is as follows:

[0028] First, activate the two electric push rods 42. The two electric push rods 42 drive the two lifting plates 43, two stops 44, baffles 45, guide plates 46, and scrapers 55 to move upward, so that scrapers 55 enter the designated position inside the discharge pipe 3. Then, open the discharge valve outside the discharge pipe 3. The concrete, after being mixed in the mixing tank 1, is discharged along the discharge pipe 3. Finally, activate the cleaning motor 52. The cleaning motor 52 drives the rotating shaft 53, mixing rod 54, and scrapers 55 to rotate. The scrapers 55 clean the inner wall of the discharge pipe 3. The concrete flows downward along the baffles 45 and guide plates 46, dispersing the concrete, reducing the impact of discharge, and reducing the amount of concrete wasted due to splashing. The concrete is collected inside the collection bucket 6, making it less likely for the concrete to adhere to the inner wall of the discharge pipe 3 during the discharge process, reducing the occurrence of blockage in the discharge pipe 3, and improving the discharge efficiency.
