Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to an asphalt spreading vehicle. Background Art

[0002] Asphalt is a complex, dark brown mixture of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a highly viscous organic liquid, often found in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material, primarily used in the coatings, plastics, rubber, and road paving industries.

[0003] Asphalt spreaders are road construction equipment that sprays asphalt onto the road surface. Asphalt spreaders are usually driven by a drive device to rotate the spiral blades to stir the asphalt mixture stored in the storage tank. When the asphalt spreader moves to the designated work site, a delivery pump is used to extract the asphalt mixture from the storage tank through a connecting pipe. The asphalt mixture is then injected into the nozzle through a delivery pipe and finally sprayed out through the nozzle. The asphalt spreader then drives the nozzle to move, thereby completing the asphalt spreading work.

[0004] In the process of stirring and mixing the asphalt mixture by spiral blades, the existing asphalt spreader has a relatively simple stirring method, and part of the asphalt mixture will accumulate at the bottom of the storage tank, thereby reducing the stirring efficiency. The asphalt mixture may even sink to the bottom and clog the nozzle. Some asphalt spreaders use multiple drive motors to stir the asphalt mixture in the storage tank at multiple angles at the same time. Although this improves the stirring efficiency, it will make the internal structure of the asphalt spreader more complicated and the cost is relatively high. For this reason, we propose an asphalt spreader. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an asphalt spreading vehicle. Through the coordinated arrangement of the spiral blades and the cross plate, the cross plate can continuously flip the asphalt mixture upwards during the process of the spiral blades stirring and mixing the asphalt mixture inside the storage tank, thereby improving the stirring efficiency. The entire process can be completed with only one motor, and the cost is relatively low. The problem of the nozzle being blocked due to the sinking of the asphalt mixture is solved, the spreading efficiency is improved, and the problems in the background technology can be effectively solved.

Through the regulation of the control switch group 2, the motor 11 starts to run, and the output shaft of the motor 11 drives the driving gear 10 to rotate. The driving gear 10 drives the gear 7 on the right to rotate through the meshing connection, and then the gear 7 on the right drives the spiral piece 62 to rotate through the output rod 61, so that the asphalt mixture stored in the storage tank 3 is stirred and mixed by the spiral piece 62.

[0031] The working principle of an asphalt spreader provided by the utility model is as follows: before use, open the feed valve, connect the feed pipe 4 with the external pipeline, and inject the asphalt mixture into the interior of the storage tank 3 through the feed pipe 4. After the asphalt compound is added, separate the feed pipe 4 from the external pipeline, and then close the connecting valve again. At this time, through the control of the switch group 2, the motor 11 starts to run, and the output shaft of the motor 11 drives the driving gear 10 to rotate. The driving gear 10 drives the gear 7 on the right to rotate through the meshing connection, and then the gear 7 on the right drives the spiral piece 62 to rotate through the output rod 61, so that the asphalt mixture stored in the storage tank 3 is stirred and mixed through the spiral piece 62. During the rotation of the driving gear 10, the driving gear 10 drives the adjusting gear 9 on the right to rotate through the meshing connection, and the adjusting gear 9 on the right drives the mounting rod 8 to rotate, so that the mounting rod 8 The left adjusting gear 9 is driven to rotate, and the left adjusting gear 9 drives the left gear 7 to rotate through meshing connection, thereby driving the sleeve 63 to rotate through the left gear 7, and the sleeve 63 drives the cross plate 65 to rotate through the fixed plate 64. Since the output rod 61 and the sleeve 63 rotate in opposite directions, the spiral blade 62 stirs and mixes the asphalt mixture in the three parts of the storage tank. During this process, the cross plate 65 can continuously flip the asphalt mixture upward to prevent the asphalt mixture from sinking to the bottom. After the asphalt spreader is driven to the designated work location, the connecting valve is opened, and then the delivery pump 54 starts to operate through the control of the switch group 2. The delivery pump 54 extracts the asphalt mixture inside the storage tank 3 through the connecting pipe 53, and then injects the asphalt mixture into the interior of the buffer tank 51 through the delivery pipe 55, and finally sprays it out through the nozzle 52, and then drives the nozzle 52 to move through the vehicle body 1, thereby realizing the asphalt spreading work.
