Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and specifically relates to a concrete production blanking device. Background Technique

[0002] Concrete is a composite material widely used in the construction and engineering fields. It is prepared by mixing cement, water, fine aggregates (such as sand), coarse aggregates (such as gravel or crushed bricks), and additives and admixtures added as necessary in a certain proportion, and then uniformly stirred, densely formed, and cured and hardened. Concrete production blanking is an important link in the concrete production process. Its advantages are fast blanking speed and high efficiency, but attention needs to be paid to the blanking sequence to reduce the phenomenon of cement flying.

[0003] The blanking device usually consists of a hopper, a conveying mechanism, a driving mechanism, etc. When the concrete is mixed, the concrete inside the mixing tank is injected into the hopper. Motors in the driving mechanism drive the conveying mechanism to operate, and quantitative conveying of the concrete can be carried out, thus completing the blanking work of the concrete.

[0004] In the current prior art, during the blanking process of the traditional concrete production blanking device, blockage is likely to occur at its outlet. Therefore, it is necessary for workers to dredge it in time. However, the existing devices are not convenient to operate, which will consume a lot of time and energy of workers, not only affecting the concrete blanking efficiency, but also reducing the use efficiency and practicability of the device.

[0005] Therefore, a concrete production blanking device is proposed to solve the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the above problems, a concrete production blanking device is proposed.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A concrete production blanking device of the present utility model includes a machine body, a hopper, and a discharge port.

A driving motor is fixedly connected to one side of the machine body. A feeding trough is opened in the middle of the machine body. A transmission rod is rotatably connected to the middle of the feeding trough. One end of the output shaft of the driving motor is fixedly connected to one end of the transmission rod. A spiral blade is fixedly connected to the outer wall of the transmission rod. The spiral blade is rotatably connected to the inner wall of the feeding trough through the transmission rod. Both ends of the feeding trough communicate with one end of the hopper and the discharge port. An opening groove is opened on one side of the hopper. A baffle is slidably connected inside the opening groove. Both ends of the baffle are fixedly connected with hydraulic push rods. One end of the outer wall of each hydraulic push rod is fixedly connected with a fixing plate. One side of each fixing plate is fixedly connected to the hopper. And the outer wall of the baffle is slidably connected to the inner wall of the hopper through two hydraulic push rods. A base is fixedly connected to the bottom of the machine body.

[0008] Preferably, limiting grooves are opened on both sides of the baffle. A limiting rod is sleeved on the inner wall of each limiting groove. One side of each limiting rod is fixedly connected to the inner wall of the hopper.

[0009] Preferably, the inner wall of the limiting groove is slidably connected to the outer wall of the limiting rod through the baffle. The baffle is snap-connected to the inner wall of the hopper through two limiting rods.

[0010] Preferably, inclined plates are fixedly connected to the inner side walls of the hopper. The plurality of inclined plates are horizontally arranged with respect to the limiting rods. And one side of each inclined plate is in contact with one side of the baffle.

[0011] Preferably, a rectangular block is fixedly connected to one side of the top of the machine body. One end of the rectangular block is fixedly connected to one side of the hopper. A positioning groove is opened on one side of the rectangular block.

[0013] The beneficial effects of the present utility model:

[0014] The utility model provides a concrete production blanking device. The contraction of a hydraulic push rod drives a baffle to slide inside an opening groove, so that the baffle fits against the inner wall of the hopper, preventing leakage of concrete during the mixing process. The hydraulic push rod pushes the baffle to move inside the opening groove, enabling the concrete to flow from the hopper into the inside of the feeding trough. Then, the driving motor is started, and the output shaft of the driving motor drives a transmission rod to rotate, driving a spiral blade to rotate inside the feeding trough, which can push the concrete to flow inside the feeding trough, enabling quantitative discharge of the concrete, preventing blockage during the blanking process, facilitating operation by workers, reducing the consumed time and energy, improving the blanking efficiency of the concrete, and enhancing the use efficiency and practicability of the device.

[0015] The utility model provides a concrete production blanking device. Two limiting rods can prevent the baffle from being misaligned inside the hopper. Further, an inclined plate is used to further improve the sealing effect at the connection between the baffle and the hopper. Moreover, when the hydraulic push rod pushes the baffle to move, it can drive a positioning block to move inside a positioning groove. Additionally, a rectangular block is used to prevent the baffle from being misaligned during the movement process, improving the connection stability between the baffle and the inner wall of the hopper, reducing the friction between structures, and extending the service life of the equipment.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 - Figure 4 The present utility model provides a concrete production blanking device, including a machine body 1, a hopper 2 and a discharge port 3. The hopper 2 is fixedly installed on one side of the top of the machine body 1, the discharge port 3 is fixedly installed on one side of the bottom of the machine body 1, a driving motor 18 is fixedly connected to one side of the machine body 1, a feeding trough 15 is opened in the middle of the machine body 1, a transmission rod 16 is rotatably connected to the middle of the feeding trough 15, one end of the output shaft of the driving motor 18 is fixedly connected to one end of the transmission rod 16, a spiral blade 17 is fixedly connected to the outer wall of the transmission rod 16, and the spiral blade 17 is rotatably connected to the inner wall of the feeding trough 15 through the transmission rod 16. Both ends of the feeding trough 15 communicate with one end of the hopper 2 and the discharge port 3. An opening groove 5 is opened on one side of the hopper 2, a baffle 6 is slidably connected inside the opening groove 5, hydraulic push rods 7 are fixedly connected to both ends of the baffle 6, a fixing plate 8 is fixedly connected to the outer wall of each hydraulic push rod 7, one side of each fixing plate 8 is fixedly connected to the hopper 2, and the outer wall of the baffle 6 is slidably connected to the inner wall of the hopper 2 through the two hydraulic push rods 7. A base 4 is fixedly connected to the bottom of the machine body 1.

[0026] During operation, the machine body 1 is moved to the bottom of the concrete mixing device, and the stability of the machine body 1 is ensured by using the base 4. Then, the hopper 2 is fixed directly below the outlet of the concrete mixing device. The stability of the hydraulic push rods 7 is ensured by the fixing plates 8. The contraction of the hydraulic push rods 7 is used to drive the baffle 6 to slide inside the opening groove 5, so that the baffle 6 fits against the inner wall of the hopper 2 to prevent leakage of concrete during the mixing process. When the concrete production is completed, the hydraulic push rods 7 are used to push the baffle 6 to move inside the opening groove 5, so that the concrete flows from the hopper 2 into the inside of the feeding trough 15. Then, the driving motor 18 is started, and the output shaft of the driving motor 18 is used to drive the transmission rod 16 to rotate, thereby driving the spiral blade 17 to rotate inside the feeding trough 15. The rotation of the spiral blade 17 can be used to push the concrete to flow inside the feeding trough 15, so that the concrete is stably discharged from the discharge port 3. And quantitative discharge of the concrete can be carried out, which can prevent blockage during the blanking process. And it is convenient for workers to operate, reducing the time and energy consumed, improving the blanking efficiency of the concrete, and improving the use efficiency and practicability of the device.

[0027] Furthermore, as Figure 3 shown, limiting grooves 9 are provided on both sides of the baffle 6. The inner wall of each limiting groove 9 is sleeved with a limiting rod 10, and one side of each limiting rod 10 is fixedly connected to the inner wall of the hopper 2. The inner wall of the limiting groove 9 is slidably connected to the outer wall of the limiting rod 10 through the baffle 6, and the baffle 6 is snap-fitted to the inner wall of the hopper 2 through the two limiting rods 10. The inner side walls of the hopper 2 are fixedly connected with inclined plates 11. The plurality of inclined plates 11 are horizontally arranged with respect to the limiting rods 10, and one side of each inclined plate 11 is in contact with one side of the baffle 6.

[0028] During operation, when the hydraulic push rod 7 drives the baffle 6 to move, it can drive the limiting groove 9 to slide outside the limiting rod 10. The two limiting rods 10 can prevent the baffle 6 from being misaligned inside the hopper 2, prevent leakage, and improve the service life of the structure. Further, the inclined plates 11 can further improve the sealing effect at the connection between the baffle 6 and the hopper 2, and can also reduce the concrete from falling on the top of the limiting rod 10 during discharge, reducing the situation of jamming of the structure.

[0029] Furthermore, as Figure 4 shown, a rectangular block 12 is fixedly connected to one side of the top of the machine body 1. One end of the rectangular block 12 is fixedly connected to one side of the hopper 2, and a positioning groove 13 is provided on one side of the rectangular block 12. The inner wall of the positioning groove 13 is sleeved with a positioning block 14. One side of the positioning block 14 is fixedly connected to one side of the baffle 6, and the positioning block 14 is slidably connected to the inner wall of the positioning groove 13 through the baffle 6.

[0030] During operation, when the hydraulic push rod 7 pushes the baffle 6 to move, it can drive the positioning block 14 to move inside the positioning groove 13. Further, the rectangular block 12 can prevent the baffle 6 from being misaligned during the movement, improve the stability of the connection between the baffle 6 and the inner wall of the hopper 2, reduce the friction between the structures, and improve the service life and practicability of the equipment.

[0031] Working principle: By moving the body 1 to the bottom of the concrete mixing device, the base 4 is used to ensure the stability of the body 1, and then the hopper 2 is fixed directly below the outlet of the concrete mixing device. The fixing plate 8 is used to ensure the stability of the hydraulic push rod 7. The contraction of the hydraulic push rod 7 drives the baffle 6 to slide inside the opening groove 5, and drives the limiting groove 9 to slide outside the limiting rod 10. The two limiting rods 10 can prevent the baffle 6 from being misaligned inside the hopper 2, so that the baffle 6 fits against the inner wall of the hopper 2. The inclined plate 11 can further improve the sealing effect at the connection between the baffle 6 and the hopper 2. When the concrete production is completed, the hydraulic push rod 7 is used to push the baffle 6 to move inside the opening groove 5, so that the concrete flows from the hopper 2 into the inside of the feeding trough 15, thereby driving the positioning block 14 to move inside the positioning groove 13. The rectangular block 12 can prevent the baffle 6 from being misaligned during the movement. Then the driving motor 18 is started. The output shaft of the driving motor 18 drives the transmission rod 16 to rotate, and then drives the spiral blade 17 to rotate inside the feeding trough 15. The rotation of the spiral blade 17 can push the concrete to flow inside the feeding trough 15, so that the concrete is stably discharged from the discharge port 3, and quantitative discharge of the concrete can be achieved.
