Description

Technical Field

[0001] The utility model relates to the technical field of concrete transfer equipment, in particular to a stirring transfer equipment for preventing concrete from solidifying. Background Art

[0002] The common means of transport for concrete transportation is a mixing tank truck. The existing concrete mixing tank truck is a standard equipment with a height of about 3.2m. This limits the application of concrete tank trucks in underground construction environments, especially in garages, basements and other places where the entrance is narrow and the entrance height is relatively low. The concrete mixing tank truck can only stay at the entrance and then rely on manual vehicles to transport concrete to the construction site. However, general transportation tools lack a mixing structure, and the concrete will dry out after a long period of transportation.

[0003] In order to solve the above problems, a mixing and transporting equipment that can prevent concrete from solidifying is needed to transport concrete to a site with height restrictions to meet actual construction needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a mixing and transferring equipment for preventing concrete from solidifying. The equipment has a mixing structure that can prevent concrete from drying out during transportation, and the transfer equipment has a low height and can be applied to construction sites with height restrictions, thereby solving the above-mentioned technical problems.

[0008] Preferably, the bottom of the open compartment is connected to the frame of the transfer vehicle, and one side of the bottom plate is fixedly connected to the front of the transfer vehicle.

[0009] Through the above technical solution, the open compartment is not provided with a top cover so that the top is open, which is convenient for loading concrete into the open compartment before transportation, and the transfer vehicle provides power to move the open compartment to the construction site. Since the open compartment is arranged as a whole on the frame of the transfer vehicle and has a regular structure and a height limited to - meters, it can enter relatively low construction sites such as underground garages and tunnels, avoiding the inconvenience caused by traditional tank trucks not being able to enter such construction sites.

[0010] Preferably, two stirring shafts are provided, and the gear set includes four gears, one of which is drivingly connected to the output shaft of the reduction box.

[0011] Through the above technical solution, a universal joint drive shaft is used to connect the input shaft of the reduction box with the output shaft of the power box of the transfer vehicle, so that the transfer vehicle can drive the reduction box to move during the starting process, and the output shaft of the reduction box is connected to one of the gears of the gear set through a sprocket and a chain. Since the four gears of the gear set are meshed with each other, the rotation of one of the gears can drive the remaining three gears to rotate, and the leftmost and rightmost gears are respectively connected to two stirring shafts, so the two stirring shafts can rotate forward and backward, and then the stirring shaft drives the connecting rod, and the connecting rod drives the spiral blade to rotate, so that the concrete loaded into the open compartment can be stirred to prevent the concrete from drying out during the movement.

[0012] Preferably, a discharge hole is formed through the outer surface of the compartment door, a lower hopper is fixedly connected to the discharge hole, and an output end of the hydraulic rod is fixedly connected to a baffle.

[0013] Through the above technical solution, when arriving at the construction site, the hydraulic rod is started to drive the baffle, and the baffle can move upward under the guidance and limitation of the two vertical plates to open the discharge hole, and then the concrete can be unloaded through the lower hopper.

[0014] Preferably, a pipe rack is installed on the top of the open compartment, and the pipe rack is fixed to the outer surface of the flushing pipe.

[0015] Through the above technical scheme, when the concrete inside the open compartment is unloaded, the booster pump is started to extract water from the water tank, and then the clean water is transported to the flushing pipe and then sprayed from a number of nozzles, so that the open compartment is flushed, making it difficult for the concrete to remain on the inner bottom surface of the open compartment.

[0016] Preferably, a plurality of nozzles are installed at equal intervals on the outer surface of the flushing pipe, and the nozzles form an angle of 15-25 degrees with the horizontal plane.

[0017] Through the above technical solution, by setting the nozzle at an angle of 15-25 degrees with the horizontal plane, the flushing range is expanded, and the concrete residue can be discharged from the lower hopper along with the water flow.

[0018] Compared with the prior art, the utility model provides a mixing and transporting device for preventing concrete from solidifying, which has the following beneficial effects:

Since the four gears of the gear set are meshed with each other, the rotation of one of the gears can drive the remaining three gears to rotate, and the leftmost and rightmost gears are respectively connected to two stirring shafts, so the two stirring shafts can rotate forward and reverse, and then the stirring shaft drives the connecting rod, and the connecting rod drives the spiral blade to rotate, so that the concrete loaded into the open compartment can be stirred to prevent the concrete from drying out during the movement.

[0020] 2. When the concrete inside the open compartment is unloaded, the utility model starts the booster pump to extract water from the water tank, and then the clean water is transported to the flushing pipe and then sprayed from a plurality of nozzles, so that the open compartment is flushed, making it difficult for the concrete to remain on the inner bottom surface of the open compartment.
