Description

Technical Field

[0001] The utility model belongs to the field of spreader equipment, in particular to a vehicle-mounted cement slurry slurry spreader. Background Art

[0002] The roadbed construction of highways generally uses cement as filler for roadbed paving. Traditional cement paving is done manually by spreading. However, this working method is not only labor-intensive but also has low work efficiency. Therefore, spreaders are used in this field. Spreaders are broadly defined as a type of equipment that can spread materials onto the ground or in the air through its operation.

[0003] A self-propelled environmentally friendly cement dry powder spreader is disclosed in a Chinese utility model patent with announcement number CN218779286U. The machine is provided with a crushing roller and a discharging plate, both of which are driven by the spreader wheels. The crushing roller can crush the cement agglomerated inside the silo to prevent the discharge port from being blocked. The discharging plate has the function of evenly discharging the material and improving the spreading accuracy. The dust-proof cloth can reduce the dust generated by the cement when spreading. By setting a baffle, the baffle increases the path of the cement discharging and prevents segmental spreading, thereby further improving the spreading accuracy.

[0004] However, when the device is spreading the mud, it is not convenient to adjust the spreading width according to the width of the road surface. When the road width is small, the sprayed mud will exceed the working range, which not only easily causes the waste of mud, but also requires cleaning of the cement in the excess area.

The bottom of the elastic filter plate 12 abuts against the top of the cam 11. There are four cams 11, and the four cams 11 are staggered to avoid contact between the cams 11 and ensure the normal operation of the cams 11. One end of the intermediate shaft of the cam 11 is connected to a rotating rod 13 through a synchronous belt drive. The feed trough 4 is provided with a rotating bearing at the bottom, the intermediate shaft of the cam 11 is provided in the rotating bearing, the intermediate shaft of the right cam 11 is connected to the front rotating rod 13 by a synchronous belt transmission, the intermediate shaft of the left cam 11 is connected to the back rotating rod 13 by a synchronous belt transmission, to ensure the normal operation of the intermediate shaft of the cam 11, so that the two rotating rods 13 respectively control the rotation of the intermediate shafts of the two cams 11, the outer side of the rotating rod 13 is sleeved with two supporting plates fixedly connected to the top of the silo 2, to ensure the normal operation of the rotating rod 13, one end of the rotating rod 13 is fixedly connected to the adjusting motor 14, and the surface of the rotating rod 13 is sleeved with the first sprocket 15.

[0034] The stirring assembly is used to stir water and cement raw materials. The stirring assembly includes a stirring rod 16. The surface of the stirring rod 16 is fixedly connected with support rods at equal intervals to facilitate stirring of the water and cement raw materials in the silo 2.

[0036] The implementation principle of a vehicle-mounted cement slurry slurry spreader in the embodiment of the present application is as follows: when the ground width changes during the operation of the device, the adjusting motor 14 is started as needed, and the adjusting motor 14 drives the rotating rod 13 to rotate, so that the first sprocket 15 drives the second sprocket 26 to rotate through the chain, so that the second sprocket 26 drives the threaded rod 23 to rotate through the connecting gear 25 and the driven gear 24. When the threaded rod 23 rotates, the threaded cylinder 22 drives the sealing disk 21 to move inside the distribution pipe 8, so that the sealing disk 21 blocks the connection between the distribution pipe 8 and part of the discharge nozzle 9, so that the discharge nozzle 9 on one side of the sealing disk 21 lacks mud supply, thereby realizing the device's adjustment of the mud spraying range, so that the device can adjust the spraying range according to different ground widths during driving.

[0037] Start the stirring motor 19, and then pour the cement raw material into the feed trough 4. The stirring motor 19 drives the driving gear 20 to rotate through the worm wheel 18 and the worm 17, so that the gear 27 rotates. The crushing roller 10 then crushes and disperses the solid in the cement raw material, so that the cement raw material and water in the device react more quickly. At the same time, under the action of the elastic filter 12, impurities in the cement raw material are filtered to reduce the impact of impurities on the discharge effect of cement.

[0038] When the device adjusts the spraying range according to the width of the ground, the adjusting motor 14 is started, and the adjusting motor 14 drives the rotating rod 13 to rotate. Under the action of the synchronous belt, the cam 11 rotates, and the cam 11 continuously hits the elastic filter plate 12 to vibrate the impurities blocked in the elastic filter plate 12, thereby reducing the blockage of the elastic filter plate 12.

[0039] When the device adds material into the silo 2, the elastic filter plate 12 is blocked, which affects the material discharge of the device. At this time, the movement of the vehicle body 1 is stopped, the pump 5 is turned off, and the regulating motor 14 is started, so that the regulating motor 14 rotates back and forth, and the cam 11 continuously rotates to hit and vibrate the bottom of the elastic filter plate 12, thereby vibrating the impurities in the elastic filter plate 12, so that the cement raw materials can enter the silo 2 more smoothly.

The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, front side, back side, left side, right side, front, back, upward, above, above, below, below, behind, and in front may be used with respect to the drawings. These and similar directional terms should not be construed as limiting the scope of the present disclosure in any way.
