Description

Technical Field

[0001] The present invention relates to the technical field of automatic lifting of grain suction machines, and specifically to an automatic lifting mechanism for an environment-friendly grain suction machine. Background Technique

[0002] A grain suction machine, also known as a pneumatic grain conveyor, is a device that uses the energy of air flow to convey granular materials in a closed pipeline. It is widely used in places such as farms, docks, stations, and large grain depots for loading, unloading, replenishing, discharging, turning over, and stacking of bulk grain, as well as in industries such as grain processing, feed processing, and beer brewing. When in use, a grain suction machine usually cooperates with a bracket to support and position the suction pipe, and at the same time, it is necessary to manually adjust its height to facilitate the grain suction operation.

[0003] When the common support and lifting device of a grain suction machine is in use, it is usually manually operated by workers. It cannot quickly complete the lifting task, which affects the work efficiency. It is difficult to accurately control the lifting height, which may cause grain spillage or equipment damage. At the same time, if the operation is improper, it may cause the equipment to become unbalanced or the grain to fall, posing certain safety hazards. In addition, it cannot clamp and position suction pipes of different sizes, cannot adapt to suction pipes of different sizes, limits the application range of the equipment, and cannot meet various working requirements, bringing certain adverse effects to the using process. Therefore, we propose an automatic lifting mechanism for an environment-friendly grain suction machine. Summary of the Invention

[0004] Technical problems to be solved: Aiming at the deficiencies of the prior art, the present invention provides an automatic lifting mechanism for an environmentally friendly grain suction machine, which has the advantages of simple operation, improved efficiency, and expanded application range. Through the provided lifting control mechanism, the first control motor drives the first rotating rod to drive the first transmission wheel to rotate inside the mobile base. The protective cover plays a protective role outside the first control motor, and the heat dissipation net on the inner wall of the protective cover can play a heat dissipation effect. The first transmission wheel drives the second transmission wheel and the second rotating rod inside it to rotate together through the belt. The second rotating rod drives the inner adjusting threaded rod at the upper end to rotate inside the outer adjusting bracket. The lifting adjusting frame is sleeved on the outer wall of the inner adjusting threaded rod through the inner adjusting thread groove. When the inner adjusting threaded rod rotates, the lifting adjusting frame can be adjusted to move up and down on its outer wall. The limiting plate plays a limiting role inside the outer adjusting bracket to prevent slipping. The automatic lifting control can simplify the operation process, reduce manual intervention, improve the convenience of operation, increase the automation degree of the equipment, reduce manual labor, optimize the working environment. Through the provided clamping and adjusting mechanism, the support and fixing frame plays a role in supporting and stabilizing at the lower end of the stable support plate. The second control motor drives the connecting through rod to drive the U-shaped adjusting frame to rotate. The adjusting block is sleeved on the outer walls of both ends of the adjusting rod through the threaded holes. The third control motor drives the adjusting rod to rotate inside the inner activity groove, so that the adjusting block moves towards each other on the outer wall of the adjusting rod, and at the same time drives the connecting plate and the semi-circular clamping block to move towards each other. The suction grain pipe is clamped and positioned by two groups of semi-circular clamping blocks. The inner anti-slip flexible pad on the inner wall of the semi-circular clamping block can play a certain protective role, can firmly clamp suction grain pipes of different sizes, avoid problems such as grain leakage and grain spilling during the grain suction process, improve work efficiency, can adapt to suction grain pipes of different sizes, expand the application range of the equipment, meet various work requirements, and can effectively solve the problems in the background technology.
