Description

Technical Field

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

[0002] Concrete, a widely used material in civil engineering, is an engineering composite material made by binding aggregates together with cementing materials. In the concrete production process, the feeding device is an important component. Currently, existing concrete feeding devices have some shortcomings. Most of them use a pipe connection method to output concrete. Although this structure is simple and low-cost, the concrete output effect is not good in actual use. Therefore, a concrete feeding device for concrete production is needed.

[0003] The existing patent document CN217891416U discloses a concrete feeding device for concrete production. The utility model includes a feeding hopper, with two symmetrically distributed support blocks fixed at the bottom of the feeding hopper. The support blocks are equipped with moving wheels at the bottom. The feeding hopper is equipped with a dredging structure inside, which includes a horizontal plate, a square block, a cylinder, a piston rod, and a conical dredging block.

[0004] However, due to the poor mixing ability of the existing patent technology with authorization announcement number CN217891416U, it is not convenient to effectively mix concrete in actual use. When concrete is put into the hopper for feeding, or when it is left for a long time before feeding, the concrete is prone to segregation or solidification, which affects the quality of subsequent construction and use of concrete, as well as feeding efficiency.

[0026] The mixing mechanism 3 includes a first motor 301. The first motor 301 is fixedly installed on one side of the storage hopper 1. The first motor 301 is electrically connected to the PLC controller 2. A first coupling 302 is fixedly installed on the output shaft end of the first motor 301. The first coupling 302 extends into the interior of the storage hopper 1. A rotating rod 303 is fixedly installed on the side of the first coupling 302 away from the first motor 301. A support connecting block 304 is fixedly installed on the inner wall of the storage hopper 1 on the side away from the first coupling 302. The side of the rotating rod 303 away from the first coupling 302 is rotatably connected to the support connecting block 304. Several stirring blades 305 are evenly fixedly installed on the outer end of the rotating rod 303. When the first motor 301 is started, the first coupling 302 is driven to rotate. Power is transmitted to the rotating rod 303 through the first coupling 302, and the several stirring blades 305 fixed on the outer end of the rotating rod 303 rotate accordingly.

[0027] The feeding mechanism 4 includes a feeding connecting pipe 401. The feeding connecting pipe 401 is fixedly installed at the bottom end of the storage hopper 1. The discharge pipe 402 is fixedly installed at the bottom end of the feeding connecting pipe 401. A second motor 403 is fixedly installed on one side of the discharge pipe 402. The second motor 403 is electrically connected to the PLC controller 2. A second coupling 404 is fixedly installed at the output shaft end of the second motor 403. The second coupling 404 extends into the interior of the discharge pipe 402. A discharge auger 405 is fixedly installed on one side of the second coupling 404. When the second motor 403 is started, it drives the second coupling 404 to rotate. The discharge auger 405 rotates in the discharge pipe 402 through the second coupling 404, so as to feed materials at a uniform speed.

[0028] An L-shaped mounting plate 5 is fixedly installed on one side of the bottom of the storage hopper 1. An electric push rod 6 is fixedly installed on the side of the L-shaped mounting plate 5 near the discharge connecting pipe 401. The electric push rod 6 is electrically connected to the PLC controller 2. A push rod 7 is fixedly installed on the output end of the electric push rod 6. A discharge baffle 8 is fixedly installed on one side of the push rod 7. The discharge baffle 8 extends movably into the interior of the discharge connecting pipe 401. A guide plate 9 is fixedly installed at the bottom of the storage hopper 1. Placement feet 10 are fixedly installed at the four corners of the bottom of the storage hopper 1. A support leg 11 is fixedly installed at the bottom of the discharge pipe 402. A reinforcing rod 12 is fixedly installed in the middle of the placement foot 10. The electric push rod 6 is controlled by the PLC controller 2. The output end of the electric push rod 6 extends or retracts, driving the push rod 7 to move, which in turn drives the discharge baffle 8 to move.

[0029] Working Principle: When concrete feeding is required, the concrete feeding device is first placed in a suitable working position. The storage hopper 1 is stably supported on the ground by the support feet 10 and the reinforcing rods 12, while the discharge pipe 402 is stably supported by the support legs 11 at its bottom, ensuring the entire device is in a stable state. Then, an external power supply is connected to power the equipment on the device. Concrete is injected into the storage hopper 1. The first motor 301 is powered on and started under the control of the PLC controller 2. The output shaft of the first motor 301 rotates, transmitting power to the rotating rod 303 through the first coupling 302. Several mixing blades 305 fixed to the outer end of the rotating rod 303 rotate accordingly, mixing the concrete in the storage hopper 1 from all directions and angles. Whether it is newly added concrete raw material or concrete that has been stored for a long time, the mixing blades 305 can continuously agitate, effectively preventing concrete segregation or solidification and ensuring the uniformity of the concrete. This is controlled by the PLC. Device 2 controls electric push rod 6. The output end of electric push rod 6 extends or retracts, driving push rod 7 to move, thereby causing discharge baffle 8 to slide outward in discharge connecting pipe 401, thus adjusting the size of discharge port of discharge connecting pipe 401 and achieving initial control of discharge amount. Subsequently, second motor 403 starts under the control of PLC controller 2. The output shaft of second motor 403 drives discharge screw auger 405 to rotate in discharge pipe 402 through second coupling 404. The guide plate 9 at the bottom of the storage hopper 1 guides concrete to discharge connecting pipe 401. Under the rotation of discharge screw auger 405, concrete is evenly discharged from discharge pipe 402, achieving stable discharge. During the entire discharge process, the speed of first motor 301 and second motor 403 and the extension and retraction of electric push rod 6 can be adjusted in real time by PLC controller 2 according to actual needs, to accurately control the mixing effect, discharge speed and discharge amount of concrete, and meet the needs of different production scenarios.
