Description

Technical Field

[0001] The utility model relates to the technical field of concrete transportation, in particular to an anti-sticking transportation device for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. The term "concrete" generally refers to cement as the binder, sand and stone as the aggregates, mixed with water (which may contain admixtures and additives) in a specific proportion, and then mixed. Cement concrete, also known as ordinary concrete, is widely used in civil engineering, and its production requires the transportation of sand, stone, and cement.

[0003] There is a concrete conveying device (authorization announcement number: CN220683760U) which starts the motor to drive the spiral conveying blades to rotate in the housing. Through the transmission assembly and the stirring shaft, when the output shaft of the motor rotates, the output shaft of the motor drives the two stirring shafts to rotate in the housing through the transmission assembly, so that the two stirring shafts rotate in opposite directions, solving the problem of the crushing device in the shaftless screw conveyor being driven by multiple motors, resulting in high production costs and low practicality when manufacturers produce shaftless screw conveyors.

[0004] However, this type of concrete conveying device has some shortcomings during actual use: during the concrete conveying process, residual concrete raw materials will adhere to the inner wall of the conveying device's shell, the spiral conveying blades and the blades of the two stirring shafts, which is inconvenient to clean. Excessive adhesion of concrete raw materials will affect the next use of the concrete conveying device; therefore, we propose a concrete production anti-sticking conveying device to solve the above problems.

[0010] Preferably, the transmission mechanism includes a sprocket and a chain, and the driving rod and the corresponding rotating rod are fixedly installed with a sprocket at one end extending through the outside of the conveyor, and the same chain is meshed and installed between the two sprockets; under the transmission action of the chain, when the driving rod rotates, the corresponding rotating rod is synchronously driven to rotate.

[0011] Preferably, the translation drive mechanism includes a second motor, a threaded rod and a guide rod. The second motor is fixedly mounted on one side of the corresponding side frame, and one end of the threaded rod is fixedly mounted on the output shaft of the second motor. The other end of the threaded rod is threadedly passed through the outside of the corresponding movable block and is rotatably mounted on an inner wall of one side of the side frame. The inner wall of the other side frame is fixedly mounted with a guide rod, and the other movable block is movably sleeved on the guide rod. Through the translation drive mechanism, the frame and the hollow tube can be reciprocated in the horizontal position.

[0012] Preferably, the multiple spray nozzles at the bottom of the hollow tube are arranged at equal distances, and the spray directions of the spray nozzles located on the outside are inclined; the polymer lubricant solution is sprayed into the conveying trough through the multiple spray nozzles.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The anti-sticking conveying device for concrete production starts a pump to pump the polymer lubricant solution stored in the anti-sticking agent storage tank into the hollow tube through the conveying pipe, and sprays the polymer lubricant solution into the conveying trough through multiple spray nozzles. The device cooperates with a translation drive mechanism to facilitate uniform spraying of the polymer lubricant solution on the inner wall of the conveying trough, the spiral conveying blades, and the surfaces of multiple stirring paddles on two sets of rotating rods. The polymer lubricant solution is uniformly sprayed on the inner wall of the conveying trough, the spiral conveying blades, and the surfaces of multiple stirring paddles on the two sets of rotating rods to form an anti-sticking protective film, thereby reducing subsequent adhesion to concrete and reducing residual concrete on the inner wall of the conveying trough, the spiral conveying blades, and the surfaces of multiple stirring paddles on the two sets of rotating rods, thereby facilitating the next use of the conveyor and improving the practicality of the conveyor.

The two rotating rods 7 are connected by a counter-rotating mechanism, and the driving rod 5 is connected to the corresponding rotating rod 7 by a transmission mechanism. Side frames 13 are fixedly installed on both sides of the conveyor 1, and movable blocks 14 are movably installed in the two side frames 13. The two movable blocks 14 are fixedly installed with the same frame 15. A translation driving mechanism for the two movable blocks 14 is provided on the two side frames 13, and a hollow tube 19 is fixedly installed on the inner wall of the frame 15. A plurality of spray nozzles 20 are provided at the bottom of the hollow tube 19, and a liquid pumping mechanism is provided between the anti-sticking agent storage tank 2 and the hollow tube 19.

[0024] Furthermore, the outer contact surface of the spiral conveying blade 6 rotates and fits on the bottom inner wall of the conveying trough 3. A discharge port 23 is opened at the bottom of one end of the conveying trough 3 to facilitate the discharge of concrete raw materials from the discharge port 23.

[0025] Furthermore, the counter-rotation mechanism includes a first gear 9 and a second gear 10. The first gear 9 and the second gear 10 are fixedly installed on one end of the two rotating rods 7 that pass through the outside of the conveyor 1, and the first gear 9 and the second gear 10 are engaged with each other; since the first gear 9 and the second gear 10 are engaged with each other, the two rotating rods 7 can be synchronously driven to rotate in opposite directions.

[0026] Specifically, the transmission mechanism includes a sprocket 11 and a chain 12. The driving rod 5 and the corresponding rotating rod 7 are fixedly installed with a sprocket 11 at one end extending through the outside of the conveyor 1, and the same chain 12 is meshed and installed between the two sprockets 11; under the transmission action of the chain 12, when the driving rod 5 rotates, the corresponding rotating rod 7 is synchronously driven to rotate.

[0027] Furthermore, the translation drive mechanism includes a second motor 16, a threaded rod 17 and a guide rod 18. The second motor 16 is fixedly installed on one side of the corresponding side frame 13, and the output shaft of the second motor 16 is fixedly installed on one end of the threaded rod 17. The other end of the threaded rod 17 is threadedly passed through the outside of the corresponding movable block 14 and is rotatably installed on the inner wall of one side of the side frame 13. The inner wall of the other side frame 13 is fixedly installed with a guide rod 18, and the other movable block 14 is movably sleeved on the guide rod 18; through the translation drive mechanism, the frame 15 and the hollow tube 19 can be reciprocated in the horizontal position.

[0028] Furthermore, the multiple spray nozzles 20 at the bottom of the hollow tube 19 are arranged at equal intervals, and the spray direction of the spray nozzles 20 located on the outside is inclined; the polymer lubricant solution is sprayed into the conveying trough 3 through the multiple spray nozzles 20.

[0029] Specifically, the liquid pumping mechanism includes a pump 21 and a delivery pipe 22. The pump 21 is provided on the top side of the anti-adhesive agent storage tank 2. The liquid pumping end of the pump 21 extends into the anti-adhesive agent storage tank 2. The liquid discharge end of the pump 21 is connected to one end of the delivery pipe 22, and the other end of the delivery pipe 22 is connected to the hollow tube 19. The anti-adhesive agent storage tank 2 stores a polymer lubricant solution. By starting the pump 21, the polymer lubricant solution is pumped into the hollow tube 19 through the delivery pipe 22.

[0030] During use: before transporting the concrete, the polymer lubricant solution stored in the anti-adhesive tank 2 is pumped into the hollow tube 19 through the delivery pipe 22 by starting the pump 21, and the polymer lubricant solution is sprayed into the delivery trough 3 through multiple spray nozzles 20. At the same time, the second motor 16 is started to drive the threaded rod 17 to rotate, so that the two movable blocks 14 drive the frame 15 to move back and forth in the horizontal position at the top opening of the delivery trough 3 of the conveyor 1. At the same time, by starting the first motor 4, the spiral conveying blade 6 and the sprocket 11 on the driving rod 5 are driven to rotate. Under the transmission action of the chain 12, the corresponding rotating rod 7 is synchronously driven to rotate, and the first gear 9 is driven to rotate. Under the meshing action with the second gear 10, the multiple stirring paddles 8 on the two rotating rods 7 are synchronously driven to rotate, so that the polymer lubricant solution is evenly sprayed on the inner wall of the conveying trough 3, the spiral conveying blades 6 and the surfaces of the multiple stirring paddles 8 on the two groups of rotating rods 7. The polymer lubricant solution is evenly sprayed on the inner wall of the conveying trough 3, the spiral conveying blades 6 and the surfaces of the multiple stirring paddles 8 on the two groups of rotating rods 7 to form an anti-sticking protective film, which reduces the subsequent adhesion with the concrete and reduces the residual concrete on the inner wall of the conveying trough 3, the spiral conveying blades 6 and the surfaces of the multiple stirring paddles 8 on the two groups of rotating rods 7, making it easier for the conveyor 1 to be used next time and improving the practicality of the conveyor 1.
