Screening machine facilitating screen changing

Abstract

The invention provides a screening machine facilitating screen changing. The screening machine facilitating screen changing comprises a connection shaft, a square column type screen net, a clamping block, a clamping groove, a containing framework, a protecting box, a semicircular discharging pipe, a spiral rod and a collecting barrel; the connection shaft is installed at the left end of the containing framework; the clamping groove is machined in the side wall in the containing framework; and the clamping block is installed in the clamping groove, and is arranged at the side end of the squarecolumn type screen net which is installed in the containing framework. Due to the design, the screening function is achieved, and meanwhile, fast disassembling and assembling can also be achieved; thecollecting barrel is arranged at the lower end of the protecting box; the semicircular discharging pipe is installed at the front end of the collecting barrel, and is internally provided with the spiral rod; the collecting barrel is installed at the rear end of the spiral rod; the rear end of the spiral rod extends into the collecting barrel; due to the design, mechanical material discharging isachieved, and the labor intensity is lowered; and the screening machine facilitating screen changing improves the maintaining efficiency and the work efficiency, and is good in stability and high in reliability.

Description

technical field [0001] The invention relates to a screening machine with easy screen replacement, which belongs to the technical field of screening machines. Background technique [0002] The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. [0003] The screens on the existing screening machines are all installed by bolts. When the screens are damaged and maintenance is required, the time for disassembly and assembly will be increased and the maintenance efficiency will be reduced. Under the action of discharge along the sloping plate, products often accumulate on the sloping plate, requiring personnel to manually discharge the material, increasing labor intensity, poor work efficiency, and increasing the probability...
