Abstract

This utility model provides a mobile concrete quantitative injection device, belonging to the technical field of concrete injection devices. It includes a vehicle body with a fixed material hopper on it and a discharge port at the bottom. An injection box is fixedly installed on one side of the vehicle body, containing a conveying trough. An auger is rotatably installed within the conveying trough, and a drive source for rotating the auger is fixedly installed inside the injection box.

By utilizing the forced and uniform pushing force generated by the auger rotating within the conveying trough, it replaces the traditional method of relying on the concrete's own weight or manual scooping for material supply. This effectively solves the problem of injection volume fluctuation caused by the mismatch between the moving speed and the discharge flow rate of the suspended hopper due to its own weight, as well as the inefficiency of manual scooping. It achieves high-precision and stable control of the concrete injection volume, significantly improving the consistency of the forming quality of permeable frames and the overall prefabrication production efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of concrete pouring devices, and in particular to a mobile concrete quantitative pouring device. Background Technology

[0002] In the field of port and waterway engineering and channel improvement, permeable frames are usually used to slow down the water flow and promote the deposition of sediment inside and around the frame, thereby stabilizing the riverbed, preventing erosion and protecting the bank slope. The manufacturing method is to arrange multiple special molds of permeable frames closely on the production site in a side-by-side and staggered manner to optimize space utilization and facilitate concrete pouring. Then, the operators pour the mixed concrete into the cavity of each mold in sequence and continuously. After the concrete has fully solidified and hardened, it is demolded to finally form a structurally stable permeable frame.

[0003] However, existing technologies have problems when pouring concrete into the aforementioned molds: On the one hand, using a suspended, movable large hopper for pouring, relying on the concrete's own weight to flow from the hopper's discharge port into the mold below, can achieve continuous and efficient operation. However, because the moving speed of the suspension system is difficult to precisely match with the concrete discharge flow generated by the hopper's own weight, it is easy to cause fluctuations in the volume of concrete poured into each mold, affecting the forming quality of the permeable frame. On the other hand, using manual methods to repeatedly scoop concrete from the transport truck and pour it into the mold can improve the accuracy of the single-mold pouring volume to some extent, but the entire operation process is slow, consumes a lot of manpower and time, and has low overall construction efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile concrete quantitative pouring device, which solves the problems of fluctuating pouring volume of suspended hoppers and low efficiency of manual material scooping in existing technologies.

[0005] According to an embodiment of this utility model, a mobile concrete quantitative pouring device includes a vehicle body, a material receiving hopper fixedly mounted on the vehicle body, a material outlet at the bottom of the material receiving hopper, a pouring box fixedly mounted on one side of the vehicle body, a material conveying trough disposed inside the pouring box, an auger rotatably mounted inside the material conveying trough, a drive source for driving the auger to rotate fixedly mounted inside the pouring box, the material outlet being connected to one end of the material conveying trough, and a flexible hose being fixedly mounted to the other end of the material conveying trough.

[0006] The technical principle of this utility model is as follows: During pouring, concrete flows from the outlet at the bottom of the hopper into the conveying trough of the pouring box below. The drive source is started to drive the auger in the conveying trough to rotate. The rotating auger blades continuously push the concrete in the trough to the end of the conveying trough and finally deliver it to the connected hose. The operator aligns the hose outlet with the pouring port of the permeable frame mold. By precisely controlling the rotation speed of the auger, the output flow rate and total amount of concrete can be stably adjusted, thereby ensuring that the amount of concrete injected into the mold each time is accurate and controllable. At the same time, the vehicle can move along the mold arrangement direction. With the flexible guidance of the hose, continuous and efficient sequential pouring operations can be carried out on multiple molds arranged side by side and in a staggered manner.

[0007] Furthermore, the drive source includes a servo motor, and the output end of the servo motor is connected to the auger drive.

[0008] Furthermore, the infusion box is provided with a receiving cavity, the servo motor is fixedly mounted on the side wall of the receiving cavity, the output end of the servo motor is fixedly connected to a drive sprocket, one end of the auger is fixedly connected to a driven sprocket, and a chain is arranged around the drive sprocket and the driven sprocket, the chain meshing with the drive sprocket and the driven sprocket respectively.

[0009] Furthermore, a number of heat dissipation holes are provided on one side of the accommodating cavity.

[0010] Furthermore, a support column is fixedly installed on one side of the vehicle body, and a rotating rod is rotatably installed on the support column. The end of the hose is detachably fixed to the end of the rotating rod.

[0011] Furthermore, a clamp is fixedly provided at the end of the rotating rod, which allows the hose to be inserted and locked in place.

[0012] Furthermore, the bottom surface of the hopper is inclined, and the discharge port is set at the lowest point.

[0013] Furthermore, the vehicle body is equipped with a steering mechanism and a drive mechanism for controlling the steering and movement of the vehicle body.

[0014] Compared with existing technologies, this utility model has the following advantages: by using the forced and uniform pushing force generated by the auger rotating in the feeding trough to replace the traditional feeding method that relies on the concrete falling by its own weight or manual scooping, and combined with the vehicle movement and hose guidance, it effectively solves the problem of fluctuation in the injection volume caused by the mismatch between the moving speed and the self-weight discharge flow of the suspended hopper, as well as the problems of low efficiency and high cost of manual scooping. It achieves high-precision and stable control of the concrete injection volume of each mold, and significantly improves the consistency of the molding quality of the permeable frame and the overall prefabrication production efficiency.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown in the figure, this utility model embodiment proposes a mobile concrete quantitative pouring device, including a vehicle body 1. The bottom of the vehicle body 1 is provided with two sets of tires, and a steering mechanism and a drive mechanism are provided to drive the tires to turn and rotate respectively, so as to control the smooth movement of the vehicle body 1. This part belongs to very mature prior art and will not be described in detail here.

[0024] like Figure 1-4As shown, a hopper 2 is fixedly installed on the vehicle body 1 to carry concrete. The shape and volume of the hopper 2 are set according to actual conditions and are not limited here. A discharge port 21 is provided at the bottom of the hopper 2. The bottom surface of the hopper 2 is inclined, and the discharge port 21 is set as the lowest point to facilitate the concrete to gather at the discharge port 21. A grouting box 3 is fixedly installed on one side of the vehicle body 1 by bolts or welding. A conveying trough 31 is provided in the grouting box 3 near the hopper 2. An auger 32 is rotatably installed in the conveying trough 31. The diameter of the auger 32 is slightly smaller than the width of the conveying trough 31. In some embodiments, the bottom part of the conveying trough 31 is set as an arc surface that can wrap around or surround the auger 32 to further increase the contact between the auger 32 and the concrete, promote concrete conveying, and avoid the conveying dead angle between the trough wall and the auger 32. It is worth mentioning that the top of the conveying trough 31 should be provided with a sealing A closed cover (standard setting, not shown in the attached drawings) is used to prevent concrete overflow or impurities from falling in. A drive source that can drive the auger 32 to rotate is fixedly installed inside the pouring tank 3. The discharge port 21 is connected to one end of the conveying trough 31 through a conveying pipe (standard setting, not shown in the attached drawings). The conveying pipe is preferably set with an arc that can uniformly discharge the material, and the discharge port 21 is as close as possible to the pouring tank 3 to reduce the length of the conveying pipe and avoid excessive concrete adhering to the conveying pipe, which would cause waste and increase cleaning difficulty. In some embodiments, a valve is installed on the conveying pipe to control the opening and closing of the conveying pipe and the concrete discharge speed. The valve is selected according to the actual situation and is not limited here. The other end of the conveying trough 31 is connected to and fixedly installed with a flexible hose 4. The flexible hose 4 is made of wear-resistant rubber, polyurethane, or ultra-high molecular weight polyethylene, etc. The flexible hose 4 can accurately control the discharge position and increase the applicability of the device.

[0025] The technical principle of this utility model is as follows: During pouring, concrete flows from the outlet 21 at the bottom of the hopper 2 into the conveying trough 31 of the pouring box 3 below. The drive source is started to drive the auger 32 in the conveying trough 31 to rotate. The rotating blades of the auger 32 continuously push the concrete in the trough to the end of the conveying trough 31 and finally deliver it to the connected hose 4. The operator aligns the outlet of the hose 4 with the pouring port of the permeable frame mold. By precisely controlling the rotation speed of the auger 32, the output flow rate and total amount of concrete can be stably adjusted, thereby ensuring that the amount of concrete injected into the mold each time is accurate and controllable. At the same time, the vehicle body 1 can move along the mold arrangement direction. With the flexible guidance of the hose 4, continuous and efficient sequential pouring operations can be carried out on multiple molds arranged side by side.

[0026] This invention utilizes the forced and uniform pushing force generated by the rotation of the auger 32 within the material conveying trough 31 to replace the traditional material supply method that relies on the concrete's own weight falling or manual scooping. Combined with the movement of the vehicle body 1 and the guidance of the hose 4, it effectively solves the problem of fluctuation in the injection volume caused by the mismatch between the moving speed and the self-weight discharge flow of the suspended hopper, as well as the problems of low efficiency and high cost of manual scooping. It achieves high-precision and stable control of the concrete injection volume of each mold, significantly improving the consistency of the molding quality of the permeable frame and the overall prefabrication production efficiency.

[0027] like Figure 1-4 As shown, according to another embodiment, the driving source further includes, but is not limited to, a servo motor, a stepper motor, or a hydraulic motor, as well as other mechanisms capable of driving the auger 32 to rotate precisely and uniformly. In this embodiment, the driving source is set as a servo motor 33, and the output end of the servo motor 33 is connected to the auger 32. Specifically, the filling box 3 is provided with a receiving cavity 36, which is adjacent to the conveying trough 31, that is, it is located on the side of the filling box 3 away from the receiving hopper 2. The servo motor 33 The servo motor 33 is fixedly mounted on the side wall of the accommodating cavity 36. Several heat dissipation holes 35 are provided on one side of the accommodating cavity 36 for heat dissipation. The output end of the servo motor 33 passes through the side wall of the accommodating cavity 36 and is fixedly connected to a drive sprocket 331. One end of the auger 32 passes through the wall of the conveying trough 31 and is fixedly connected to a driven sprocket 321. It should be noted that the auger 32 and the wall of the conveying trough 31 need to be sealed to prevent concrete from entering. A chain is arranged around the drive sprocket 331 and the driven sprocket 321. 34. The chain 34 meshes with the drive sprocket 331 and the driven sprocket 321 respectively. A protective shell 37 is also fixedly installed on one side of the filling box 3. The protective shell 37 can protect the drive sprocket 331, the driven sprocket 321 and the chain. Based on the above configuration, the transmission ratio between the servo motor 33 and the auger 32 can be adjusted by changing the relative size of the drive sprocket 331 and the driven sprocket 321. Compared with the direct connection between the output end of the servo motor 33 and the rotating shaft of the auger 32, the sprocket and chain 34 mechanism can adjust the transmission ratio between the servo motor 33 and the auger 32. The high speed of the servo motor 33 is converted into the high torque required by the auger 32, avoiding the motor from directly bearing the sudden large load when the concrete gets stuck. In addition, the chain 34 can skip teeth or break in case of extreme overload, protecting the servo motor 33 from stall damage. It also allows the servo motor 33 and the auger 32 shaft to be arranged in a non-linear manner, improving the space utilization of the grouting box 3. In some embodiments, the sprocket and chain 34 structure can also be replaced with a gear structure, and the power transmission is completed through the direct meshing between the gears. The specific driving method can be selected according to the actual situation and is not limited here.

[0028] like Figure 4-6As shown, according to another embodiment, further, a support column 11 is fixedly installed on one side of the vehicle body 1, and a rotating rod 12 is rotatably installed on the support column 11. The end of the hose 4 is detachably fixed to the end of the rotating rod 12 with its end facing outward. For easy disassembly, a clamp 5 is fixedly installed at the end of the rotating rod 12. The clamp 5 allows the hose 4 to be inserted and locked. Specifically, the clamp 5 includes an upper clamp 51 and a lower clamp 52 that are hinged to each other. The bottom of the lower clamp 52 is fixedly connected to the rotating rod 12, and its connection end with the upper clamp 51 is rotatably provided with... A threaded rod 53 is threadedly connected to a knob 54. The connecting end of the upper clamp 51 is provided with a slot 55 that allows the threaded rod 53 to rotate and be inserted into the slot 55. After the threaded rod 53 is rotated into the slot 55, it can be locked by rotating the knob 54 against the side wall of the connecting end of the upper clamp 51. Based on the above improvements, the hose 4 can be quickly fixed to the rotating rod 12 by the clamp 5, and the rotation angle can be adjusted by the rotating rod 12 to achieve precise control of the concrete pouring position. There is no need for manual pipe holding for pouring, further reducing labor costs.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
