Shock Absorbing Device for Slurry Sealing Vehicle Belt Conveyor

Abstract

The invention discloses a damping device for a belt conveyor of a slurry seal paver, and belongs to the technical field of vehicle damping. The damping device comprises a belt conveyor supporting plate, an auxiliary frame, an upper rubber damping pad, a lower rubber damping pad and a damping pad bed plate, wherein the upper rubber damping pad and the lower rubber damping pad are connected with the belt conveyor supporting plate through a bolt; and the damping pad bed plate is connected with the auxiliary frame through bolts. The damping device for the belt conveyor of the slurry seal paver is simple in structure and convenient to use, greatly reduces the vibration during rigid connection of the chassis auxiliary frame and the belt conveyor through a double-layer rubber damping structure, reduces the influence of self vibration of the paver on a belt scale system, and realizes high accuracy metering and stone distribution.

Description

technical field [0001] The invention relates to a shock absorbing device, in particular to a shock absorbing device used for slurry seal vehicle aggregate conveying belt scales, and belongs to the technical field of vehicle shock absorbing. Background technique [0002] Slurry sealer is a special equipment used for asphalt pavement maintenance and maintenance. It uses appropriately graded stone chips as aggregates, emulsified asphalt as a binder, and adds a certain proportion of cement, lime, fly ash, mineral powder, etc. Powder, additives, water and other materials are mixed to make a uniform slurry mixture, and spread evenly on the road surface according to the required thickness and width to form a thin layer of asphalt surface treatment. The slurry sealing vehicle is used to maintain the surface of high-grade roads and municipal roads, which can reduce noise, save energy, and prolong the service life of the road; during the production of this asphalt aggregate, it is nec...

AI Technical Summary

Problems solved by technology

The slurry sealing vehicle is used to maintain the surface of high-grade roads and municipal roads, which can reduce noise, save energy, and prolong the service life of the road; during the production of this asphalt aggregate, it is necessary to transport the stone chips to the weighing After weighing on the scale, mix according to the required ratio. At present, the method of weighing and mixing is a closed-loop control volumetric weighing method. According to the preset ratio requirements, through the signal of the load cell and the speed sensor, the joint control of the variable speed hydraulic pressure The motor adjusts the speed of the belt-driven rollers to the actual required speed, and directly transports the proportionally required stone chip raw materials to the mixing device. However, the car is always moving forward during this process. Due to the unevenness of the road surface and the instability of the driving speed , the vibration caused has a great impact on the load cell on the belt conveyor, which will cause instability in its weighing and seriously reduce the measurement accuracy of the belt scale system
