Description

Asphalt concrete transfer truck with foldable side operation position Technical Field The invention relates to the field of road construction machinery, in particular to an asphalt concrete transfer vehicle with foldable side operation positions. Background The asphalt concrete transfer vehicle is matched equipment for construction operation of an asphalt concrete surface layer of a high-grade highway, and has the functions of rapidly receiving and storing the mixture from the material transfer vehicle and transmitting the mixture to a paver. In general, a material handling vehicle directly discharges a mixture into a paver to perform construction operation on a road surface, and when each material handling vehicle finishes discharging and changes a next material handling vehicle, the paver needs to be stopped for waiting, the stable state of continuous construction is destroyed, and defects that the road surface flatness is affected by indentation or lifting and the like easily occur at the road surface at the stop position. Meanwhile, the shutdown also causes the reduction of the pavement construction efficiency. Asphalt concrete transfer truck equipment is added between the material conveying truck and the paver, so that the paver is prevented from being in direct contact with the material conveying truck, the paver is guaranteed to be free of interference and continuous construction operation, and accordingly high-quality pavement is guaranteed to be paved. Meanwhile, the transfer trolley has a secondary stirring function, and can stir the mixture for the second time in the process of transporting the mixture, so that temperature segregation and aggregate segregation generated in the process of producing, transporting and unloading the asphalt mixture are eliminated to the maximum extent, and the temperature and grading of the asphalt mixture are uniform and consistent. The method provides an effective solution for improving the construction quality and efficiency of the highway, prolonging the service life of the highway, saving maintenance cost and reducing environmental pollution and resource waste. In the process of unloading the material mover to the material mover, a construction operator is usually required to be equipped and is responsible for commanding the butt joint of the material mover and the material mover, controlling the unloading speed of the material mover and the speed of the mixed material in the material receiver of the material mover to be transferred to the material storage bin of the material mover. Therefore, it is necessary to provide a control panel at the left and right sides of the transfer cart near the rear of the receiving hopper to control the lifting, opening and closing of the gate, and control of the feeding speed of the receiving hopper. However, in the construction of the prior art, the problems are that 1, the comfort is poor, an operator needs to move along with the travelling of a transfer trolley, fatigue is easy to cause in long-time operation, 2, potential safety hazards are that the operator walks on a road surface which is not finished in construction for a long time, particularly when the operator approaches the edge of the road surface, the operator falls down or falls down, and 3, the observation is inconvenient, the side wall of a receiving hopper is high, and the operator is prevented from directly observing the state of materials. Therefore, there is a need to develop a new asphalt concrete transfer vehicle specifically to overcome the above problems. Disclosure of Invention Aiming at the defects and defects of the prior art, the invention provides the asphalt concrete transfer truck with the foldable side operation positions, wherein the foldable side operation positions are arranged at the left side and the right side of the transfer truck and lean against the rear part of the receiving hopper, so that an operator can sit to operate during construction. The invention relates to an asphalt concrete transfer vehicle with a foldable side operation position, which comprises the following components: A receiving hopper for receiving paving material; the mixed material received by the receiving hopper is conveyed to a first-stage conveying device in the storage bin; Control panels arranged on two sides of the rear part of the receiving hopper and used for controlling the lifting of the receiving hopper, the opening and closing of the material door and the material conveying speed; the foldable side operation position is arranged at the rear part of the receiving hopper and corresponds to the control panel, and the side operation position comprises a mounting seat, a supporting frame, a stool surface and pedals. The support frame is hinged with the mounting seat through a rotary pin shaft and a limiting pin shaft, and the limiting pin shaft is provided with two groups of mounting holes for limiting the support frame to be in a horizontal working position a
