Conveniently change branch sieve machine of screen cloth

Technical Field

The utility model belongs to the technical field of screening plant's technique and specifically relates to a conveniently change branch sieve machine of screen cloth.

Background

The present screening machine, also called screening machine, is widely used for screening coarse and fine materials, and the process of dividing the broken materials into different size fractions through one or more layers of screen surfaces is called screening. The sieving machine is a vibrating sieving mechanical device which utilizes the relative movement of bulk materials and a sieve surface to lead partial particles to penetrate through sieve pores and divide materials such as sand, gravel, broken stone and the like into different grades according to the particle size. The screening process of the screening machine is generally continuous, after screening raw materials are fed onto a screening machine (called a screen for short), materials smaller than the size of the screen holes penetrate through the screen holes and are called undersize products; material larger than the mesh size is continuously discharged from the screen surface, called oversize product, where the screen is a worn item and needs to be replaced periodically.

The traditional Chinese patent with reference publication number CN208449838U discloses a vibrating screen classifier, which comprises a plurality of screen layers, wherein each screen layer comprises a middle frame, the top and the bottom of each middle frame are respectively provided with a protruding part, the protruding direction of each protruding part is far away from the central line of the vibrating screen classifier, the outer wall of each middle frame is provided with a discharge hole, the inner wall of each middle frame is provided with an upper screen clamping plate and a lower screen clamping plate, a screen is detachably arranged between the upper screen clamping plate and the lower screen clamping plate, a sealing gasket is arranged between the bottom protruding part of the middle frame of the upper screen layer and the top protruding part of the middle frame of the adjacent lower screen layer, the bottom protruding part and the top protruding part are externally sleeved with a hoop, and the head end and the tail end of the hoop are connected through; the lower surface of the upper screen clamping plate is provided with a convex part, the upper surface of the lower screen clamping plate is provided with a groove, a hook part is arranged between the upper screen clamping plate and the lower screen clamping plate on the inner wall of the middle frame, the upper screen clamping plate and the lower screen clamping plate are both annular, and a net hanging port is arranged on the upper screen clamping plate and the lower screen clamping plate so that a hand can stretch into the upper screen clamping plate and hang the screen on the hook part.

When carrying out the screen cloth and changing, need pull down the bolt earlier, thereby pull down the staple bolt, the center is pulled down promptly, later hand is taken the screen cloth and is hung on the portion of colluding of center inner wall with pressing from both sides the net gape on the net gape earlier through last double-layered otter board and lower double-layered otter board, then prevent the striking ball on holding in the palm the comb, press from both sides the otter board at last, press from both sides the otter board down, it is fixed with the screen cloth and support the comb to set up bolt and each annex in the bolt mounting hole of the relative setting of support comb, place sealed the pad between the center of adjacent sieve layer, it is just right to the adjacent sieve layer.

The above prior art solutions have the following drawbacks: when the screen cloth is replaced, the screen cloth needs to be hung on the hook part, then the screen cloth is fixed with the upper screen clamping plate and the lower screen clamping plate by using bolts, and then the middle frame is installed, so that the replacement of the screen cloth is complicated.
