Abstract

The invention discloses an automatic rake chain tensioning device for a gantry rake machine, which comprises an adjusting screw rod, two ends of the adjusting screw rod are sleeved with axle sleeves, and tensioning wheels are sleeved on the two axle sleeves. The contact between the tensioning wheel and the bushing is provided with a spacer ring, the spacer ring is fixedly sleeved on the surface of the bushing, the surface of the spacer ring is provided with a boss, and the boss is stuck on the inner surface of the tensioning wheel, and the two tensioning wheels The outer adjusting screw is sequentially sleeved with a slider, an anti-slip shock-absorbing rubber ring and a positioning nut. The two ends of the adjusting screw are provided with a lubricating mechanism. The lubricating mechanism includes an oil cup fixed on the two ends of the adjusting screw. The oil cup passes through the lubrication channel. An oil pipe is connected, and the mouth of the oil pipe is located at the junction of the spacer ring and the shaft sleeve.

Description

technical field [0001] The invention belongs to the technical field of rake machine accessories, and relates to an automatic rake chain tensioning device of a door type rake machine. Background technique [0002] The rake machine is a large-scale automation equipment with high degree of automation, perfect safety measures and high work efficiency. It is an ideal transportation equipment used in bulk warehouses. It is mainly used for sorting and transportation of bulk warehouses in large-scale urea industry and glass industry. Among them, the rake plate is the part in direct contact with the material, and the force of the rake plate driven by the rake chain is used to rake the material to realize the finishing of the material. [0003] However, in the long-term operation, the rake chain of the rake machine will produce loose chains or stacked chains, which will affect the working efficiency of the rake machine, cause chain wear or sprockets and chains cannot be meshed normall...
