Technical Field

The invention belongs to the technical field of sieve sheets, and particularly relates to a quick-release sieve sheet assembly.

Background

The screen sheet is a main part for screening solid-phase particles by the vibrating screen and plays roles in throwing the particles and grading and screening. The sieve piece is easy wearing and tearing at the screening in-process screening surface, need frequently change the sieve piece, therefore quick overspeed device tensioner has important influence to improving shale shaker work efficiency, and traditional sieve piece tensioning mode roughly divide into bolt tightening type, voussoir pressing mode and gear shaft roll up the formula three kinds, uses the voussoir pressing mode most extensively wherein, and this tensioning mode adopts the manual work to strike to impel the wedge to remove usually, compresses tightly fixed sieve piece through the voussoir. In the vibrating screen with a double-layer vibrating screen or a stepped screen sheet arrangement mode, a lower-layer screen sheet adopts a wedge block compression mode, and wedge locking and dismounting operations of wedge blocks are difficult to perform.

In order to overcome the defects of the wedge block tensioning device, the invention particularly provides a quick-release type screen assembly.

Disclosure of Invention

The invention aims to: in order to solve the technical problems that a wedge block tensioning device in the prior art is inconvenient to disassemble and assemble and poor in firm effect, a quick-release type sieve plate assembly is provided.

The technical scheme adopted by the invention is as follows:

the utility model provides a quick detach formula sieve piece subassembly, includes sieve piece and box curb plate, the fixed limiting plate that is provided with on the box curb plate, the joint has a spacing piece between sieve piece and the limiting plate, and the stopper upper end is provided with spacing rack, and spacing rack toothing is connected with the location rack, and fixed cover is equipped with spacing axle in the location rack, and spacing off-axial side rotates the cover and is equipped with spacing fixed axle, and spacing fixed axle runs through the box curb plate and is formed with the installation department.

According to the invention, the handle is assembled on the inner side of the mounting part, so that the limitation that the handle is arranged on the outer side in the traditional sense is broken, the handle is prevented from being disassembled outside and is directly disassembled inside, the operation by one person is convenient, and the practicability is higher.

In a further preferred embodiment of the present invention, the handle is a ratchet wrench, and the ratchet wrench is detachably connected to the limit shaft.

According to a further preferred embodiment of the present invention, the limiting rack is located at the large head end of the limiting block.

According to a further preferable embodiment of the invention, the surface of the limiting rack is provided with a first tooth groove, the positioning rack is provided with a second tooth groove matched with the first tooth groove, and the first tooth groove is meshed with the second tooth groove.

The working principle is as follows: when the screen piece disassembling device works, the ratchet wrench is used for clockwise rotating the limiting shaft, the limiting shaft rotates (limits) in the limiting fixed shaft, the limiting block moves inwards to be wedged tightly, so that the screen piece is pressed tightly, the ratchet wrench is used for anticlockwise rotating the limiting shaft, so that the limiting block moves outwards, the limiting block is loosened, the limiting shaft is directly disassembled, the limiting block is more convenient to take out, and therefore the screen piece is convenient to disassemble.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. the invention drives the limit shaft to rotate on the side plate of the box body, the ratchet wrench easily installs the limit block in place, when the sieve sheet needs to be disassembled, the ratchet wrench is used for clockwise rotating the limiting shaft, the limiting shaft rotates (limits) in the limiting fixed shaft, so that the limiting shaft moves inwards along the limiting block, the limiting block is wedged tightly, thereby pressing the sieve sheets tightly, using the ratchet wrench to rotate the limiting shaft anticlockwise, leading the limiting shaft to move outwards along the limiting block, loosening the limiting block, directly detaching the limiting shaft, more conveniently taking out the limiting block, thereby facilitating the disassembly of the sieve sheet, having simple structure and simple operation, being more convenient to use compared with the traditional mode of manually knocking the wedge block and taking out the wedge block, being more easy to disassemble compared with the prior art because the limit shaft and the limit fixed shaft can be directly disassembled, and the ratchet wrench is assembled on the limiting shaft, so that the ratchet wrench and the gear can be more conveniently disassembled.

2. The handle is assembled on the inner side of the installation part, the limitation that the handle is arranged on the outer side in the traditional sense is broken, the disassembly outside is avoided, the disassembly is directly performed in the inner part, and the operation by one person is facilitated.
