Description

A crushing and screening machine

technical field

The utility model relates to the technical field of crushing and screening, in particular to a crushing and screening machine.

Background technique

In industrial production, crushing equipment and screening equipment are common industrial production equipment. At present, both the crushing equipment and the screening equipment are single-unit equipment, and it is generally necessary to install a conveyor belt or a material transfer tool between the two sets of equipment to transport the crushed material from the pulverizer to the screening equipment through the conveyor belt for grading and screening, making the production process complicated. Moreover, the number of devices is large, which requires a large amount of energy consumption, resulting in higher production costs.

Utility model content

The technical problem to be solved by the utility model is to provide a crushing and screening machine with simple production process, energy saving and low production cost.

In order to solve the above problems, a crushing and screening machine described in the utility model includes a motor, a transmission box, a housing, a rotating shaft b, an eccentric wheel and a chain rod assembly, and the upper part of the housing is provided with a shaft dynamically connected to both sides of the housing. Rotating shaft a, one end of the rotating shaft a extends outward through the housing; the part of the rotating shaft a in the housing is provided with a crushing blade; reciprocating mesh screen; the upper part of the housing is provided with a material inlet, and the lower part is provided with a material outlet; the outwardly extending end of the rotating shaft a is connected to the transmission box, and the transmission box is provided with a meshing active A bevel gear and a driven bevel gear, one side of the driving bevel gear is connected to the rotating shaft a, and the other side is connected to the motor; the driven bevel gear is vertically connected to one end of the rotating shaft b, and the other end of the rotating shaft b is connected to the eccentric wheel, and the eccentric wheel is connected to the mesh screen through the chain rod assembly.

Further, the crushing blades are evenly arranged across.

Further, the two ends of the slot are respectively provided with baffle plates, and the distance between the two baffle plates is the maximum moving distance when the mesh screen reciprocates.

Further, the lower part of the housing is a tilting mechanism.

Compared with the prior art, the utility model has the following advantages;

1. The utility model combines the crushing equipment and the screening equipment into one, and the power source can drive the crushing equipment and the screening equipment to work at the same time, which saves energy and reduces production costs;

2. The materials of the utility model are crushed by the crushing equipment and directly fall into the reciprocating mesh screen below to screen the materials. The crushing and screening can be completed at the same time, making the production process simple.

Detailed ways

According to a crushing and screening machine shown in Figure 1, it includes a motor 1, a transmission box 3, a housing 7, a rotating shaft b9, an eccentric wheel 10 and a chain rod assembly 11, and the upper part of the housing 7 is provided with a shaft dynamically connected to both sides of the housing 7. Rotating shaft a4, one end of the rotating shaft a4 extends outward through the housing 7; the part of the rotating shaft a4 in the housing 7 is provided with crushing blades 5 that are evenly arranged across; 15 is provided with a reciprocating mesh screen 13; the two ends of the card slot 15 are respectively provided with baffle plates 14, and the distance between the two baffle plates 14 is the maximum movement distance when the mesh screen 13 reciprocates; the upper part of the housing 7 There is a material inlet 6, and its lower part is provided with a material outlet 12, and the lower part of the shell 7 is an inclined structure; one end of the rotating shaft a4 extending outward is connected to the transmission box 3, and the transmission box 3 is provided with a driving bevel gear that meshes with each other. 2 and the driven bevel gear 8, one side of the driving bevel gear 2 is connected to the rotating shaft a4, and the other side is connected to the motor 1; the driven bevel gear 8 is vertically connected to one end of the rotating shaft b9, and the other end of the rotating shaft b9 is connected to the eccentric wheel 10, and the eccentric wheel 10 The mesh screen 13 is connected by a link assembly 11 .

The specific implementation of the utility model is as follows: start the motor 1, the motor 1 drives the driving bevel gear 2 and the rotating shaft a4 to rotate, the rotating shaft a4 drives the 5 crushing knives to rotate at high speed, and the driving bevel gear 2 drives the driven bevel gear 8 to rotate at the same time, and the driven bevel gear The gear 8 drives the eccentric wheel 10 to rotate through the rotating shaft b9. When the eccentric wheel 10 rotates, the chain bar assembly 11 drives the mesh screen 13 to reciprocate. Screening is carried out on the moving mesh screen 14, and the screened materials are discharged through the discharge port 12. Since the mesh screen 13 has a certain elasticity, when the materials with larger particles bounce with the reciprocating motion of the mesh screen 13 during screening, they are crushed by the crushing blade 5. The flakes can be crushed again, and the crushing and screening work can be completed at one time, so that the production process is simple, the number of equipment is small, energy is saved and production costs are reduced; The end is scattered, which improves the screening quality.
