Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a high liquid limit clay sand mixing equipment. Background Technology

[0002] High liquid limit clay is a type of clay with high water content, low hardness, and high viscosity and plasticity. With the deepening of my country's resource utilization and sustainable development concepts, research on the resource utilization of high liquid limit clay is constantly innovating. Currently, high liquid limit clay can be used for roadbed filling after being improved by sand mixing. The sand mixing process requires the use of mixing equipment to blend the high liquid limit clay with sand into sand. For example, a sand mixing device disclosed in Chinese Patent No. CN215848865U includes a cover and a body. The cover is disc-shaped, with two vertical motors on top. These vertical motors are connected to a vertical stirring paddle below the cover. A horizontal motor is located between the vertical motors, and a transmission chain is connected to the horizontal motor. The transmission chain passes through a notch in the cover and connects to a transmission gear below the cover. The transmission gear is connected to a gear stirring paddle. The body is located below the cover, and a discharge pipe is located at the bottom of the body.

[0003] However, in practical applications, although the above-mentioned equipment can mix high liquid limit clay with sand, the sand and soil mixed with sand are difficult to be discharged from the mixing equipment due to the high water content of high liquid limit clay and the fact that the equipment is closed. This makes cleaning quite difficult and also affects the secondary use of the equipment, resulting in the utilization rate of high liquid limit clay still not being very high. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a high liquid limit clay sand mixing device, which makes it easier to discharge the sand mixed with sand, avoids the accumulation of the mixed sand inside the device, and allows for secondary use without cleaning, thereby improving the utilization rate of high liquid limit clay.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high liquid limit clay-sand mixing device includes a frame, a mixing cylinder rotatably connected to the frame, a mixing drive assembly for driving the mixing cylinder to rotate, a discharge port located at one end of the mixing cylinder, a discharge gate covering the discharge port, a pusher plate slidably connected inside the mixing cylinder, a pusher drive assembly for driving the pusher plate to slide, the pusher plate and the discharge gate being fixedly connected by a connecting column, and a feed pipe provided on the mixing cylinder.

[0007] Furthermore, two driving gears are provided on the outer wall of the mixing cylinder, and two driven shafts one and two driven shafts two are rotatably connected to the frame. The two driven shafts are coaxially arranged, and the two driven shafts two are coaxially arranged. Driven gears one and two are respectively provided on driven shafts one and two, and driven gears one and two mesh with driving gears respectively. The mixing drive assembly includes a motor fixed on the frame and a double-head reducer connected to the output shaft of the motor. The two output ends of the double-head reducer are respectively connected to the two driven shafts one.

[0008] Furthermore, the end of the mixing cylinder away from the discharge port is sealed by a sealing plate; the pushing drive assembly includes multiple electric cylinders fixed on the sealing plate, and the piston rods of the electric cylinders extend horizontally to drive the pushing plate.

[0009] Furthermore, the sealing plate is also provided with multiple mixing blades, and the pusher plate is provided with through holes facing the mixing blades. During the process of the pusher plate sliding left and right along the inner wall of the mixing cylinder, the pusher plate slides along the mixing blades through the through holes.

[0010] Furthermore, a feed funnel is connected to the top of the feed pipe, and a valve is installed on the feed pipe.

[0011] Furthermore, it also includes a controller, wherein both the hybrid drive assembly and the pusher drive assembly are electrically connected to the controller.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, during use, the pusher drive assembly drives the pusher plate to move to the right along the mixing cylinder. The pusher plate, through the connecting column, drives the discharge gate to close. High liquid limit clay and sand can be fed into the mixing cylinder through the feed pipe. The mixing drive assembly drives the mixing cylinder to rotate, mixing the high liquid limit clay and sand into sand. After mixing, the pusher drive assembly drives the pusher plate to move to the left along the mixing cylinder. The pusher plate, through the connecting column, drives the discharge gate to open. The pusher plate continues to move to the left, pushing the sand in the mixing cylinder out of the discharge port. This invention makes it easier to discharge the sand mixed with sand, avoiding the accumulation of the mixed sand inside the equipment. It also eliminates the need for cleaning and allows for reuse, improving the utilization rate of high liquid limit clay. Attached Figure Description

The mixing drive assembly drives the mixing cylinder 2 to rotate, mixing the high liquid limit clay and sand into sand. After mixing, the pusher drive assembly drives the pusher plate 4 to move to the left inside the mixing cylinder 2. The pusher plate 4 drives the discharge gate 3 to open via the connecting column 41. The pusher plate 4 continues to move to the left, pushing the sand in the mixing cylinder 2 out of the discharge port.
