[0001] This utility model relates to the field of pipe pile production technology, and in particular to a feeding device for a pipe pile mixing plant. Background Technology

[0002] The core function of the feeding device in a mixing plant is to accurately deliver the mixed concrete into the steel cage of the pipe pile, providing a uniform and continuous material supply for the pipe pile forming. It is a key piece of equipment connecting the concrete preparation and pipe pile pouring processes.

[0003] The existing feeding device has the following problems during use:

[0004] First, the drop outlet is prone to blockage, and concrete residue can easily remain inside the device;

[0005] Secondly, if the drop outlet is not properly aligned with the steel cage when feeding material into the steel cage, it can easily lead to concrete spillage.

[0006] Third, when concrete falls into the steel cage from the chute, local accumulation is likely to occur, resulting in uneven distribution. Utility Model Content

[0007] The purpose of this utility model is to provide a feeding device for a pipe pile mixing plant, which can avoid blockage of the drop outlet and residual concrete inside the device, reduce cleaning and maintenance costs, and ensure that the drop outlet is precisely aligned with the reinforcing cage, effectively reducing material waste and keeping the working environment clean. When the concrete falls into the reinforcing cage, it is evenly distributed without accumulation, which can ensure the quality of pipe pile pouring.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a pipe pile mixing plant, comprising a symmetrically arranged base, on which a support column is fixedly arranged, and between the two support columns, a crossbeam and a top beam at the same height are fixedly arranged from bottom to top along the height direction, a material dropping mechanism is fixedly arranged between the two crossbeams, a feeding mechanism is arranged directly above the material dropping mechanism, a vibration mechanism is arranged on both sides of the feeding mechanism, and a drive mechanism is arranged on the vibration mechanism.

[0009] By adopting the above technical solution, vibration can keep the concrete in the feeding mechanism in a flowing state and prevent the concrete from accumulating and blocking at the drop outlet.

[0010] A further feature of this invention is that the feeding mechanism includes a material frame and a feeding hopper fixedly connected to the material frame. The material section of the feeding hopper is composed of an elastic compensation section and a rigid connection section. The elastic compensation section and the rigid connection section are distributed at intervals and are fixedly connected to each other.

[0011] By adopting the above technical solutions, the flowability of materials in the hopper can be enhanced, and residue and maintenance costs can be reduced.

[0012] The present invention is further configured such that: the driving mechanism includes a power source, the vibration mechanism includes a spring, the lower end of the spring is fixedly provided with a support plate that is fixedly connected to the lowest rigid connecting section of the hopper, the upper end of the spring is fixedly connected with a connecting seat that is fixedly connected to the material frame, the support plate is also fixedly provided with a positioning sleeve that is sleeved on the outside of the spring, and the connecting seat is fixedly provided with a guide cylinder that is sleeved on the outside of the spring, and the spring, the positioning sleeve, and the guide cylinder are coaxial.

[0013] By adopting the above technical solution, the design of the positioning sleeve and guide shaft can prevent the spring from bending and shifting laterally during vibration, ensuring the stability and reliability of vibration transmission and ensuring the vertical vibration of the hopper.

[0014] A further feature of this invention is that a force transmission shaft is fixedly mounted on the support plate, a slot is provided on the upper part of the force transmission shaft, an opening is provided in the middle of the connecting seat, a transmission rod is provided between the opening and the slot, a first protrusion and an upper connecting shaft are provided in the opening, one end of the connecting shaft is fixedly connected to the first protrusion, and the outer side is rotatably connected to the transmission rod, a power source is fixedly mounted on the rear side of the connecting seat, the output shaft of the power source passes through the connecting seat and is fixedly connected to the lower end of the first protrusion in the opening, the lower end of the transmission rod is rotatably connected to the slot through a lower connecting shaft, both ends of the lower connecting shaft are fixed to the slot, and the bottom end of the transmission rod is rotatably connected to the lower connecting shaft.

[0015] By adopting the above technical solution, the high-frequency vibration generated by the power source driving the transmission rod is superimposed with the elastic vibration of the spring to form a composite vibration effect, which more effectively breaks up concrete lumps and prevents the hopper from clogging.

[0016] A further feature of this invention is that a second protrusion is provided inside the opening. The second protrusion and the first protrusion are symmetrically arranged inside the opening via the upper end of the transmission rod. The other end of the upper connecting shaft is fixedly connected to the second protrusion. The lower end of the second protrusion is rotatably connected to a transmission shaft that passes through the connecting seat. The transmission shaft and the connecting seat are rotatably connected. A transmission wheel is fixedly provided at the outer end of the transmission shaft. A belt that drives the vibration mechanism on the other side is sleeved on the transmission wheel.

[0017] By adopting the above technical solution, the vibration mechanism on the other side is synchronously driven through the second protrusion and the transmission wheel-belt system, so that both sides of the hopper receive uniform vibration excitation, avoiding deviation or tilting caused by unilateral force. Furthermore, the power is transmitted to the vibration mechanism on the other side by belt drive, eliminating the need for an additional power source, simplifying the system structure and reducing energy consumption.

[0018] The present invention is further configured as follows: the material feeding mechanism includes a material feeding box located directly below the material feeding hopper, the two sides of the material feeding box are fixedly connected to the crossbeam respectively, the bottom of the material feeding box is a semi-circular concave surface, the diameter of the concave surface is the same as the diameter of the pipe pile mold cavity, the two sides of the concave surface are provided with discharge ports, the middle of the concave surface is provided with a baffle, and the top of the baffle is arc-shaped.

[0019] By adopting the above technical solution, not only can the material be accurately injected into the cavity of the pipe pile mold, but the material can also be evenly dispersed in the cavity of the pipe pile mold.

[0020] A further feature of this invention is that the material of the elastic compensation section is one of chloroprene rubber, polyurethane rubber, or nitrile rubber.

[0021] By adopting the above technical solutions, the three types of rubber can absorb impact energy through their own deformation, reduce wear caused by rigid collisions, and maintain stable compensation performance during repeated deformation, making them suitable for working conditions with frequent vibrations.

[0022] The beneficial effects of this utility model are:

[0023] 1. It can avoid blockage of the drop outlet and residual concrete inside the device, reduce cleaning and maintenance costs, reduce production interruptions caused by blockage, and improve the continuous operation efficiency of the equipment.

[0024] 2. The precise alignment of the drop outlet with the upper opening of the pipe pile mold cavity can effectively reduce concrete spillage, reduce material waste, and maintain a clean working environment.

Detailed Implementation

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] like Figures 1 to 4 As shown, this utility model provides a feeding device for a pipe pile mixing plant, including symmetrically arranged bases 101, each base 101 is fixedly provided with a support column 102, and a crossbeam 103 and a top beam 104 at the same height are fixedly provided between the two support columns 102 from bottom to top along the height direction. A material dropping mechanism 2 is fixedly provided between the two crossbeams 103, a material unloading mechanism 3 is provided directly above the material dropping mechanism 2, a vibration mechanism 4 is provided on both sides of the material unloading mechanism 3, and a drive mechanism 5 is provided on the vibration mechanism 4.

[0034] Specifically, the vibration mechanisms 4 installed on both sides of the feeding mechanism 3 can generate vibration under the action of the drive mechanism 5. This vibration can keep the concrete in the feeding mechanism 3 in a flowing state, prevent the concrete from accumulating and blocking at the drop outlet, and at the same time promote the smooth fall of the residual concrete inside the device, reducing cleaning and maintenance costs.

[0035] Furthermore, the feeding mechanism 3 includes a material frame 301 and a feeding hopper 302 fixedly connected to the material frame 301. The material section of the feeding hopper 302 is composed of an elastic compensation section 303 and a rigid connection section 304. The elastic compensation section 303 and the rigid connection section 304 are distributed at intervals and are fixedly connected to each other.

[0036] The rigid connection section 304 ensures the structural strength of the hopper 302 and the vibration transmission efficiency of the vibration mechanism 4, while the elastic compensation section 303 is used to absorb impact, compensate for deformation, and reduce stress concentration and blockage; such as Figure 2 As shown, both the upper and lower ends of the hopper 302 are rigid connecting sections 304. Several elastic compensation sections 303 and rigid connecting sections 304 are provided between the upper and lower ends. The elastic compensation sections 303 and rigid connecting sections 304 are distributed at intervals. Specifically, the lower part of the hopper 301 is first welded to the rigid connecting section 304. Then, starting from this rigid connecting section 304, downwards, there is a section of elastic compensation section 303, a section of rigid connecting section 304, and another section of elastic compensation section 303. The elastic compensation section 303 and the rigid connecting section 304 are fixedly connected by vulcanization bonding. The end of the support plate 402 near the hopper 302 is welded to the rigid connecting section 304.

[0037] The spaced arrangement of the elastic compensation section 303 and the rigid connection section 304 ensures uniform vibration transmission, enhances the flowability of materials in the feed hopper 302, reduces residue and maintenance costs, and also buffers noise, adapting to the working requirements under complex conditions.

[0038] Furthermore, the drive mechanism 5 includes a power source 501, and the vibration mechanism 4 includes a spring 401. One end of the spring 401 is fixedly connected to a support plate 402 that is fixedly connected to the rigid connecting section 304 at the bottom of the hopper 302. The other end of the spring 401 is fixedly connected to a connecting seat 403 that is fixedly connected to the material frame 301. A positioning sleeve 404 is also fixedly installed on the support plate 402, which is sleeved on the spring 401. That is, the bottom end of the positioning sleeve 404 and the lower end of the spring 401 are both fixedly installed on the support plate 402. The inner diameter of the positioning sleeve 404 is the same as the outer diameter of the spring 401. The positioning sleeve 404 and the spring 401 are collinear in their central longitudinal axes. The positioning sleeve 404 provides positioning and constraint for the spring 401, thus improving stability. A guide cylinder 405 is fixedly installed on the connecting seat 403, which is sleeved on the outside of the spring 401. That is, the top end of the guide cylinder 405 and the upper end of the spring 401 are both fixed on the connecting seat 403. The inner diameter of the guide cylinder 405 is the same as the outer diameter of the spring 401. The central longitudinal axes of the guide cylinder 405 and the spring 401 are collinear. The guide cylinder 405 also provides positioning and constraint for the spring 401, thus improving stability and cooperating with the vertical vibration of the hopper 302.

[0039] The spring 401, the positioning sleeve 404, and the guide sleeve 405 are coaxial. The sum of the vertical lengths of the positioning sleeve 404 and the guide sleeve 405 is less than the length of the spring 401 in its natural state, which provides space for the spring 401 to contract.

[0040] Furthermore, a force transmission shaft 406 is fixedly installed on the support plate 402. A slot 407 is opened on the upper part of the force transmission shaft 406, and an opening 408 is opened in the middle of the connecting seat 403. A transmission rod 409 is arranged between the opening 408 and the slot 407. A first protrusion 410 and an upper connecting shaft 411 are arranged in the opening 408. One end of the upper connecting shaft 411 is fixedly connected to the first protrusion 410, and its outer side is rotatably connected to the transmission rod 409. A power source 501 is fixedly installed on the rear side of the connecting seat 403. The output shaft of the power source 501 passes through the connecting seat 403 and is fixedly connected to the lower end of the first protrusion 410 in the opening 408. The lower end of the transmission rod 409 is rotatably connected to the slot 407 through a lower connecting shaft 412. Both ends of the lower connecting shaft 412 are fixed to the slot 407, and the bottom end of the transmission rod 409 is rotatably connected to the lower connecting shaft 412.

[0041] Specifically, the output shaft of the power source 501 drives the first protrusion 410 to rotate, and the first protrusion 410 drives the transmission rod 409 to move up and down through the upper connecting shaft 411, thereby realizing the up and down movement of the force transmission shaft 406.

[0042] In the initial state, the elastic compensation section 303 is in its natural state, and the support plate 402 is fixedly connected to the rigid connection section 304. When the force transmission shaft 406 drives the support plate 402 to move up and down, the elastic compensation section 303 folds or stretches. With its own elastic deformation characteristics, the elastic compensation section 303 cleverly absorbs the vertical displacement generated by the hopper 302 during the up and down vibration. It provides flexible deformation space for the reciprocating motion of the hopper 302, and also helps to maintain the dynamic balance of the hopper 302 through its own elastic reset ability. It effectively buffers the impact force during vibration transmission, avoids component wear that may be caused by rigid connection, and ensures that the vibration energy is concentrated on the concrete feeding process, improving the anti-blocking and uniform material distribution effect.

[0043] The power source 501 uses an electric motor. The high-frequency vibration generated by the motor driving the transmission rod 409 is superimposed with the elastic vibration of the spring 401 to form a compound vibration effect, which more effectively breaks up concrete lumps and prevents the hopper 302 from getting blocked.

[0044] Furthermore, a second protrusion 413 is provided inside the opening 408. The second protrusion 413 and the first protrusion 410 are symmetrically arranged inside the opening 408 via the upper end of the transmission rod 409. The other end of the upper connecting shaft 411 is fixedly connected to the second protrusion 413. The lower end of the second protrusion 413 is rotatably connected to a transmission shaft 414 that passes through the connecting seat 403. The transmission shaft 414 and the connecting seat 403 are rotatably connected. A transmission wheel 415 is fixedly provided at the outer end of the transmission shaft 414. A belt 416 that drives the vibration mechanism 4 on the other side is sleeved on the transmission wheel 415.

[0045] Specifically, since one end of the upper connecting shaft 411 is fixedly connected to the first protrusion 410 and the other end of the upper connecting shaft 411 is connected to the second protrusion 413, the output shaft of the power source 501 first drives the first protrusion 410 to rotate, and through the transmission of force, drives the transmission shaft 414 to rotate. The transmission wheel 415 is fixedly connected to the transmission shaft 414, and then drives the vibration mechanism 4 on the other side synchronously through the belt 416, so that both sides of the hopper 302 receive uniform vibration excitation, avoiding the offset or tilt caused by unilateral force. Furthermore, the power is transmitted to the vibration mechanism 4 on the other side by the belt 416, eliminating the need for an additional power source 501, simplifying the system structure and reducing energy consumption.

[0046] Furthermore, the material feeding mechanism 2 includes a material feeding box 201 located directly below the material feeding hopper 302. The two sides of the material feeding box 201 are fixedly connected to the crossbeam 103 respectively. The bottom of the material feeding box 201 is a semi-circular concave surface 202. The diameter of the concave surface 202 is the same as the diameter of the pipe pile mold cavity 6. The two sides of the concave surface 202 are provided with discharge ports 203, and a baffle 204 is left in the middle of the concave surface 202.

[0047] Specifically, the diameter of the semi-circular concave surface 202 matches the cavity 6 of the pipe pile mold, forming a guide channel with the same curvature as the mold cavity, avoiding material splashing or uneven accumulation caused by the deviation of the dropping angle, and ensuring that the material is accurately injected into the cavity 6 of the pipe pile mold.

[0048] The discharge ports 203 on both sides of the concave surface 202, together with the central baffle 204, automatically divide the falling concrete into two symmetrical material flows. The baffle 204 can not only break up the lumps in the falling material, but also block the concentrated falling material in the central area, forcing the material to be evenly dispersed to both sides. This solves the problem of unbalanced material distribution in the mold caused by single-point material feeding in the traditional material feeding mechanism 2. The top of the baffle 204 is arc-shaped to prevent concrete from falling into the upper surface of 204 and accumulating.

[0049] Furthermore, the material of the elastic compensation section 303 is one of chloroprene rubber, polyurethane rubber, or nitrile rubber.

[0050] Specifically, all three types of rubber have high elastic modulus. When equipment vibrates, displaces, or is subjected to uneven force, they can absorb impact energy through their own deformation, reduce wear caused by rigid collisions, and maintain stable compensation performance during repeated deformation, making them suitable for working conditions with frequent vibrations.

[0051] It is worth noting that a feeding mechanism is provided above the unloading mechanism 3, which provides the mixed concrete to the unloading mechanism 3. In this application, the positions of the unloading mechanism 3 and the dropping mechanism 2 are fixed. A conveyor belt is provided below the pipe pile mold cavity 6. The conveyor belt moves the pipe pile mold cavity 6 forward. The speed at which the conveyor belt moves the pipe pile mold cavity 6 matches the speed at which the material is discharged from the discharge port 203 of the dropping mechanism 2, ensuring that no concrete accumulates in the pipe pile mold cavity 6. After a pipe pile mold cavity 6 is filled with material, the conveyor belt continues to transport the next pipe pile mold cavity 6 to the discharge port 203 for filling.

[0052] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
