Problems solved by technology

[0003] In more developed areas, equipment with high automation is often used for screening and separation, but the price of the equipment is relatively high, the equipment is large in size, and difficult to maintain; therefore, when rural people build houses, due to economic constraints, they often cannot Buying or renting a large screening mechanism often uses manual separation of sand and gravel, which consumes a lot of time and manpower

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 , a layered gravel screening machine includes a frame body, a screening mechanism, a crank slider mechanism, and a spring extrusion mechanism; the screening frame 3 is fixed on the support frame 2, and is driven by the support frame 2 to slide together; the crank slider The mechanism is arranged on the right slide rail on the frame body 1, and the drive motor 13 drives the crank 8 to rotate, and then drives the support frame 2 to reciprocate; Moving the extruded spring further drives the relative movement of the receiving frame 4 and the screening frame 3 to realize the screening function.

[0019] like figure 2 and image 3 , the right slide rail on the rack body 1 is composed of front pin 1-1, rear pin 1-2, chute 1-1, front notch 1-4, rear notch 1-5, left slide rail It has the same characteristics as the right slide rail and is symmetrical...

Abstract

The invention provides a layered type sand and stone screening machine. The layered type sand and stone screening machine comprises a rack body, a screening mechanism, a crank sliding block mechanismand two spring extrusion mechanisms, wherein a driving motor is fixedly installed on a receiving frame, and a screening frame is driven to perform reciprocating motions through the crank sliding blockmechanism; first extrusion springs are installed between the front end of a sliding rail and the receiving frame, second extrusion springs are installed between the receiving frame and the screeningframe, and third extrusion springs are installed between a supporting rack and the tail end of the sliding rail; and the extrusion springs generate reverse extrusion force under driving of the crank sliding block mechanism, the receiving frame and the screening frame are made to perform rapid relative motions, and sand and stone screening separation is realized. The layered type sand and stone screening machine has the advantages of being compact in structure, low in cost, easy to operate and the like, the labor force can be greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and relates to a layered gravel screening machine. Background technique [0002] With the rapid development of today's society, people's requirements for a better life are gradually increasing, and the population is growing. A large number of houses need to be built, and sand and gravel are necessary raw materials for house construction. However, due to their different sizes and shapes, they must be Screening of sand and gravel. [0003] In more developed areas, more automated equipment is often used for screening and separation, but the price of the equipment is high, the equipment is large, and it is difficult to maintain; therefore, when rural people build houses, due to economic conditions, they often cannot When buying or renting a large screening mechanism, manual sand and gravel separation is often used, which consumes a lot of time and manpower. [0004] Therefore, a lay...
