If the discharge amount at locations with small usage cannot be accurately controlled, concrete may overflow, resulting in material waste. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a concrete feeding device for concrete production, which has the advantage of concrete discharge control. It solves the problem that during the discharge process, due to the different concrete demand at different locations, if the discharge amount at locations with small usage cannot be accurately controlled, concrete may overflow, resulting in material waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete feeding device for concrete production, comprising a discharge pipe and a discharge hopper, wherein the discharge hopper is fixedly connected to the bottom of the discharge pipe, a connecting pipe is fixedly connected to the bottom of the discharge pipe, a first distribution plate is fixedly connected to the bottom of the inner wall of the connecting pipe, a second distribution plate is movably connected to the inner wall of the connecting pipe, through grooves are provided on both sides of the top of the first distribution plate and both sides of the top of the second distribution plate, a rotating component is provided in the inner cavity of the connecting pipe, and a positioning mechanism is provided on the surface of the connecting pipe.

[0007] In a preferred embodiment of this invention, the rotating assembly includes an inner annular groove and an annular plate. The inner annular groove is formed on the inner wall of the connecting pipe, and the annular plate is fixedly connected to the surface of the second distributing plate. The annular plate is slidably connected to the inner annular groove.

[0008] In a preferred embodiment of this utility model, the positioning mechanism includes a positioning hole, an arc-shaped groove, a positioning element, a tension spring, and a fixing plate. The arc-shaped groove is formed on the surface of the connecting pipe, and the positioning hole is formed at the bottom of the surface of the connecting pipe. Several positioning holes are provided and are distributed in a ring at equal intervals. A sleeve is fixedly connected to the surface of the ring plate, and the tension spring is fixedly connected inside the sleeve. The fixing plate is disposed on the surface of the connecting pipe, and the positioning element is fixedly connected to both sides of the back of the fixing plate. The other end of the tension spring is fixedly connected to the top of the back of the fixing plate. The tension spring is sleeved on the surface of the top positioning element, and the bottom positioning element is movably connected to the positioning hole.

[0009] As a preferred embodiment of this utility model, both sides of the inner wall of the positioning hole are provided with sliding grooves, and both sides of the surface of the positioning component are fixedly connected with sliders, which are slidably connected to the sliding grooves.

[0010] As a preferred embodiment of this utility model, an arc-shaped plate is movably connected to the bottom of the surface of the connecting pipe, and a slide rail is fixedly connected to the bottom of the arc-shaped plate.

[0011] As a preferred embodiment of this utility model, an outer annular groove is formed at the bottom of the surface of the connecting pipe, and a sliding plate is fixedly connected to the inner side of the arc-shaped plate, with the sliding plate slidably connected to the outer annular groove.

[0012] As a preferred embodiment of this utility model, guide plates are provided on both sides of the top of the slide rail, and the bottom of the guide plates is fixedly connected to the top of the slide rail.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a connecting pipe, a first distribution plate, a second distribution plate, and a through groove, allows concrete to be discharged through the overlapping through groove of the first distribution plate when it enters the connecting pipe from the discharge hopper. This solves the problem that during the discharge process, the different concrete demand at different locations may lead to concrete overflow and material waste if the discharge amount at locations with small usage cannot be accurately controlled. This invention has the advantage of concrete discharge control.

[0015] 2. This utility model, by setting a rotating component, allows for adjustment of the discharge port size by first rotating the second distribution plate, which then drives the annular plate to rotate. The annular plate then rotates within the inner annular groove, aligning its through-slot with that of the first distribution plate. A positioning mechanism is then used. When the second distribution plate drives the annular plate to rotate within the inner annular groove to align its through-slot with that of the first distribution plate, a fixed plate is moved. This causes the fixed plate to pull the positioning element out of the positioning hole. Simultaneously, the fixed plate stretches the tension spring inside the sleeve. The annular plate then rotates within the arc-shaped groove to adjust the through-slot size. After adjustment, the top positioning element aligns with the positioning hole, releasing the tension spring and moving the fixed plate. The fixed plate then inserts the positioning element into the positioning hole, completing the positioning after the through-slot size adjustment.

[0016] 3. This utility model, by setting a sliding groove and a slider, allows the positioning component to move when the fixed plate moves, which in turn moves the slider. This causes the top positioning component to move inside the positioning hole and the bottom positioning component to move inside the sleeve, thus limiting the movement of the positioning component and preventing it from rotating inside the positioning hole and sleeve. Furthermore, by setting an arc-shaped plate and a slide rail, when concrete flows out from inside the connecting pipe, it flows out from the slide rail fixedly connected to the arc-shaped plate, thereby allowing the slide rail to guide the concrete to be placed at a distance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] like Figures 1 to 3 As shown, the present invention provides a concrete feeding device for concrete production, including a discharge pipe 1 and a discharge hopper 2. The discharge hopper 2 is fixedly connected to the bottom of the discharge pipe 1. A connecting pipe 3 is fixedly connected to the bottom of the discharge pipe 1. A first distribution plate 4 is fixedly connected to the bottom of the inner wall of the connecting pipe 3. A second distribution plate 5 is movably connected to the inner wall of the connecting pipe 3. Through grooves 6 are provided on both sides of the top of the first distribution plate 4 and both sides of the top of the second distribution plate 5. A rotating component 7 is provided in the inner cavity of the connecting pipe 3. A positioning mechanism 8 is provided on the surface of the connecting pipe 3.

[0023] refer to Figure 2 The rotating assembly 7 includes an inner annular groove 71 and an annular plate 72. The inner annular groove 71 is formed on the inner wall of the connecting pipe 3. The annular plate 72 is fixedly connected to the surface of the second distributing plate 5. The annular plate 72 is slidably connected to the inner annular groove 71.

[0024] As a technical optimization of this utility model, by setting a rotating component 7, when it is necessary to adjust the size of the discharge port, firstly, the second material distribution plate 5 is rotated, then the second material distribution plate 5 drives the annular plate 72 to rotate, and then the annular plate 72 rotates inside the inner annular groove 71, thereby rotating the second material distribution plate 5 so that its through groove 6 communicates with the through groove 6 of the first material distribution plate 4 to adjust the size of the through groove 6.

[0025] refer to Figure 3The positioning mechanism 8 includes a positioning hole 81, an arc-shaped groove 82, a positioning element 83, a tension spring 84, and a fixing plate 85. The arc-shaped groove 82 is formed on the surface of the connecting pipe 3. The positioning hole 81 is formed at the bottom of the surface of the connecting pipe 3. Several positioning holes 81 are provided and are distributed in a ring at equal intervals. A sleeve 86 is fixedly connected to the surface of the annular plate 72. The tension spring 84 is fixedly connected to the inside of the sleeve 86. The fixing plate 85 is provided on the surface of the connecting pipe 3. The positioning element 83 is fixedly connected to both sides of the back of the fixing plate 85. The other end of the tension spring 84 is fixedly connected to the top of the back of the fixing plate 85. The tension spring 84 is sleeved on the surface of the top positioning element 83. The bottom positioning element 83 is movably connected to the positioning hole 81.

[0026] As a technical optimization of this utility model, by setting a positioning mechanism 8, when the second material distribution plate 5 drives the annular plate 72 to rotate in the inner annular groove 71 so that its through groove 6 communicates with the through groove 6 of the first material distribution plate 4, the fixed plate 85 is moved so that the fixed plate 85 drives the positioning member 83 to be pulled out from the inside of the positioning hole 81. At the same time, the fixed plate 85 drives the tension spring 84 inside the sleeve 86 to be stretched. Then, the annular plate 72 is rotated from the inside of the arc groove 82 to adjust the size of the through groove 6. After the adjustment is completed, the top positioning member 83 is aligned with the positioning hole 81, the tension spring 84 releases its tension and drives the fixed plate 85 to move. Then, the fixed plate 85 drives the positioning member 83 to be inserted into the inside of the positioning hole 81, thereby completing the positioning after the size adjustment of the through groove 6.

[0027] refer to Figure 3 Both sides of the inner wall of the positioning hole 81 are provided with sliding grooves 9, and both sides of the inner wall of the sleeve 86 are fixedly connected with sliders 10, which are slidably connected to the sliding grooves 9.

[0028] As a technical optimization of this utility model, by setting the sliding groove 9 and the slider 10, when the fixed plate 85 drives the positioning member 83 to move, the positioning member 83 drives the slider 10 to move, and then the top positioning member 83 moves inside the positioning hole 81 and the bottom positioning member 83 moves inside the sleeve 86, thereby limiting the movement of the positioning member 83 and preventing the positioning member 83 from rotating inside the positioning hole 81 and the sleeve 86.

[0029] refer to Figure 1 An arc-shaped plate 11 is movably connected to the bottom of the surface of the connecting pipe 3, and a slide rail 12 is fixedly connected to the bottom of the arc-shaped plate 11.

[0030] As a technical optimization of this utility model, by setting up an arc plate 11 and a slide rail 12, when concrete flows out from inside the connecting pipe 3, the concrete flows out from the slide rail 12 fixedly connected to the arc plate 11, thereby enabling the slide rail 12 to guide the concrete to be thrown to a distance.

[0031] refer to Figure 2 An outer ring groove 13 is provided at the bottom of the surface of the connecting pipe 3, and a sliding plate 14 is fixedly connected to the inner side of the arc plate 11. The sliding plate 14 is slidably connected to the outer ring groove 13.

[0032] As a technical optimization of this utility model, by setting an outer ring groove 13 and a sliding plate 14, the arc plate 11 drives the sliding plate 14 to rotate, and then the sliding plate 14 rotates inside the outer ring groove 13, thereby rotating the arc plate 11 can adjust the slide rail 12 to guide the direction of concrete delivery.

[0033] refer to Figure 1 Guide plates 15 are provided on both sides of the top of the slide rail 12, and the bottom of the guide plates 15 is fixedly connected to the top of the slide rail 12.

[0034] As a technical optimization of this utility model, by setting a guide plate 15, when concrete flows out from the slide rail 12, the guide plate 15 blocks the splashed concrete from the slide rail 12, preventing material waste from splashing during the concrete feeding process.

[0035] The working principle and usage process of this utility model are as follows: When concrete enters the connecting pipe 3 from the discharge hopper 2 and the size of the discharge port needs to be adjusted, the fixed plate 85 is moved, causing the positioning part 83 to be pulled out from the positioning hole 81. At the same time, the fixed plate 85 causes the tension spring 84 inside the sleeve 86 to be stretched. Then, the annular plate 72 is rotated from inside the arc groove 82 to adjust the size of the through groove 6. After the adjustment is completed, the top positioning part 83 is aligned with the positioning hole 81, causing the tension spring 84 to release its tension and move the fixed plate 85. Then, the fixing plate 85 drives the positioning member 83 to be inserted into the positioning hole 81, thereby completing the positioning after the size adjustment of the through groove 6. This gives it the advantage of concrete discharge control. At the same time, when the fixing plate 85 drives the positioning member 83 to move, the positioning member 83 drives the slider 10 to move. Then, the top positioning member 83 moves inside the positioning hole 81 and the bottom positioning member 83 moves inside the sleeve 86, thereby limiting the movement of the positioning member 83 and preventing the positioning member 83 from rotating inside the positioning hole 81 and the sleeve 86.

[0036] In summary, this concrete feeding device for concrete production, through the arrangement of a connecting pipe 3, a first distribution plate 4, a second distribution plate 5, and a through groove 6, solves the problem of concrete overflow and material waste caused by the inability to accurately control the feeding amount at locations with varying concrete demand during the hopper feeding process. This is achieved by setting up a connecting pipe 3, a first distribution plate 4, a second distribution plate 5, and a through groove 6. When concrete enters the connecting pipe 3 from the discharge hopper 2, the second distribution plate 5 is rotated, and the size of the through groove 6 on the second distribution plate 5 is adjusted to match the size of the through groove 6 on the first distribution plate 4.
