Description

Technical Field

[0001] The utility model relates to the technical field of concrete, and in particular to a concrete screening and stirring device. Background Art

[0002] Concrete is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion, and the cement concrete obtained by mixing, also known as ordinary concrete, is widely used in civil engineering. Before using concrete, it needs to be mixed and screened to avoid the impurities inside it affecting the firmness of the concrete after solidification, which requires the use of a concrete screening and mixing device.

[0003] The document of the prior art publication number CN213644867U provides a concrete screening and mixing device, which includes a screening body, a screen mesh is provided at the bottom of the screening body, a first shaft is fixedly installed at the left end of the screening body, the first shaft is rotatably connected to the support plate, a second shaft is fixedly installed at the right end of the screening body, the second shaft is rotatably connected to the support plate, a seat plate is fixedly installed between the two support plates, a nozzle is embedded on the seat plate, a water pipe is embedded and installed on the seat plate, and the water pipe is connected to the lifting pump in a socket connection. The utility model operates through the first cylinder, drives the first rack to act on the first wheel, and reciprocates the screening body through the second shaft, so that the small particles of concrete on the screening body leak down from the screen mesh, and after the screening body rotates, the concrete is affected by the semi-convex column, so that the concrete is easy to roll, and after reciprocating motion, the small particles of concrete can be more fully separated from the screen mesh, and when the screen mesh rotates to the side, it is sprayed by the water of the nozzle, so that the screen mesh is not easy to be blocked, and the good filtering performance of the screen mesh is ensured.

[0004] The above-mentioned equipment is operated by the first cylinder, which drives the first rack to act on the first wheel, and the second shaft makes the sub-screen body reciprocate, so that the small particles of concrete on the sub-screen body leak down from the screen. After the sub-screen body rotates, the concrete is acted upon by the semi-convex columns, which makes the concrete easy to roll. After the reciprocating motion, the small particles of concrete can be more fully separated from the screen. When the screen rotates to the side, it is sprayed with water from the nozzle, which makes the screen not easy to be blocked, thereby ensuring the good filtering performance of the screen. However, when the equipment is screening concrete, after the concrete falls onto the surface of the screen, since the screen is in a fixed state, it is difficult to vibrate and shake it during screening to make the concrete pass through the screen quickly. This results in too much concrete staying on the surface of the screen, and the concrete solidifies, resulting in the blockage of the screen. This requires the staff to improve the equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the situation in the prior art that a concrete screening and mixing device is difficult to make concrete pass through the screen quickly, resulting in the concrete solidifying on the screen surface, thereby providing a concrete screening and mixing device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A tank body, wherein a first support plate is arranged on the top of the tank body, a first servo motor is arranged on the top of the first support plate, an eccentric shaft is arranged at the output end of the first servo motor, a second support plate is rotatably connected to the bottom of the eccentric shaft, fixed frames are arranged on both sides of the second support plate, and a screen is arranged on the inner wall of the fixed frame.

[0009] As an optional technical solution, a second servo motor is arranged on both sides of the top of the second support plate, a rotating shaft is arranged at the output end of the second servo motor, and a stirring blade is arranged on the surface of the rotating shaft.

[0010] As an optional technical solution, support frames are provided on both sides of the tank body, and a base is provided at the bottom of the support frame.

[0011] As an optional technical solution, a clamping block is provided on the surface of the support frame, and the surface of the clamping block overlaps the bottom of the tank body.

[0012] As an optional technical solution, discharge grooves are provided on both sides of the tank body, and the bottom of the tank body is unobstructed and the concrete can be directly discharged from the bottom of the tank body.

[0013] As an optional technical solution, a protection box is provided at the bottom of the first support plate, and the surface of the fixing frame overlaps the inner wall of the tank body.

[0014] As an optional technical solution, a third servo motor is arranged on one side of the support frame, and a tank body is arranged at an output end of the third servo motor.

[0015] As an optional technical solution, a roller is provided at the bottom of the base, the support frame is trapezoidal and the tank body can rotate to degrees in the support frame.

[0016] The utility model technical solution has the following advantages:

[0017] 1. The utility model drives the eccentric shaft to rotate through the first servo motor. Since the axial position of the eccentric shaft is offset, the eccentric shaft drives the fixed frame to rotate when it rotates. The fixed frame rotates around the eccentric shaft to perform reciprocating vibrations, thereby driving the concrete in the screen to vibrate. After being shaken, the concrete can pass through the screen more quickly, effectively improving the screening efficiency of the equipment. The shaking screen can effectively prevent excessive accumulation of concrete on the surface of the screen, thereby causing the screen to be blocked. In addition, the screening step and the stirring step of the equipment can be performed simultaneously, effectively improving the working efficiency of the equipment.

[0018] 2. The utility model drives the rotating shaft to rotate through the second servo motor, and the rotation of the rotating shaft drives the stirring blades to rotate, thereby stirring the concrete in the screen, so that the concrete is fully mixed with other materials, and during screening, the rotating stirring blades can effectively prevent the solidification of the concrete and allow the concrete to be quickly screened through the screen.
