DETAILED DESCRIPTION

The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in Figures 1 to 5, an embodiment provides a non-ferrous metal scrap crusher, comprising a hollow receiving box 2, a door (not shown) for taking out the crushed material is arranged on the side wall of the receiving box 2, a connected crushing box 1 is arranged on the top of the receiving box 2, two crushing rollers 12 are arranged in the crushing box 1, and a feed hopper 11 is arranged on the top of the crushing box 1. The above is the prior art, and its principle is that the non-ferrous metal scrap is added into the feed hopper 11, and then is crushed by the two crushing rollers 12 and then falls into the receiving box 2 for collection;

The invention of this application is:

An air inlet pipe 21 for air intake is arranged on the left side wall of the receiving box 2, an exhaust pipe 44 for exhaust is arranged on the right side wall of the receiving box 2, a grille 43 is arranged inside the receiving box 2, and the gas is discharged from the exhaust pipe 44 after being filtered by the grille 43;

An inclined plate 3 is arranged below the crushing box 1, and the inclined plate 3 extends from the bottom of the right wall of the crushing box 1 in FIG. 1 to the lower left direction. A vertical plate 31 is arranged at the bottom of the inclined plate 3, and two horizontally extending strip-shaped plug holes (not shown) are arranged vertically at intervals on the vertical plate 31, and a plug plate 32 is arranged in the plug hole;

The air inlet pipe 21 is located below the plug plate 32, that is, on the left side wall of the material receiving box 2 in FIG. 1 .

Two cylinders 33 are arranged in the material receiving box 2 , and the ends of the telescopic rods of the two cylinders 33 are fixedly connected to the two plug plates 32 respectively.

A vibration motor (not shown) in the prior art is arranged at the bottom of the inclined plate 3 .

During use, the external fan is continuously started to supply air to the receiving box 2. After the materials are crushed, they fall to the inclined plate 3 and are concentrated above the plug plate 32. At this time, the upper plug plate 32 is opened, and the materials fall onto the lower plug plate 32. Then the upper plug plate 32 is closed, and the lower plug plate 32 is opened, and the materials fall into the receiving box 2. During the falling process, the air sent in by the air inlet pipe 21 blows away the dust attached to the materials. At the same time, other debris attached to the materials, such as plastic cloth, is also peeled off. After that, when passing through the grille 43, large pieces of debris are intercepted by the grille 43, and the dust is discharged from the exhaust pipe 44 and sent to subsequent processing equipment, such as a bag dust collector or a cyclone dust collector. When the batch of waste materials is processed, the fan is turned off and the crushed materials in the receiving box 2 can be taken out. The grille 43 intercepts the plastic cloth to avoid clogging the bag dust collector or the cyclone dust collector.

However, if the grille 43 is blocked, it needs to be cleaned manually. Therefore, in order to make the cleaning of the grille 43 more convenient, please continue to refer to Figures 1 to 5. It should be noted that in Figures 3 to 5, the side walls of the two filter boxes 41 that are away from each other are hidden to show their internal structures more clearly.

Specifically, a filter mechanism 4 is arranged in the receiving box 2, and the filter mechanism 4 includes two filter boxes 41 arranged at intervals along the axis direction of the crushing roller 12, the two filter boxes 41 are opposite to each other and are rectangular, the opposite surfaces of the two filter boxes 41 are open, a grid 43 is arranged between the two filter boxes 41, and a movable plate 42 is arranged in the filter box 41;

An opening 411 is provided on the side wall of the filter box 41 near the open end, and there are two exhaust pipes 44, one end of each of the two exhaust pipes 44 is connected to the two openings 411 respectively;

A strip hole 412 is provided at the top of the filter box 41 along the axis direction of the crushing roller 12, and an L-shaped rod 421 is provided on the opposite sides of the two moving plates 42, and the vertical section of the L-shaped rod 421 extends out from the strip hole 412;

A vertical rod 431 is provided on the top of the grille 43;

The filter mechanism 4 further includes a guide rod 45 parallel to the crushing roller axis 121. The guide rod 45 penetrates the two filter boxes 41. Through holes are provided on the movable plate 42 and the grille 43. The guide rod 45 passes through a plurality of through holes. There may be a plurality of guide rods 45 and a plurality of through holes.

The crushing roller 12 further comprises a control mechanism 5 for controlling the movement of the moving plate 42 and the grid 43 along the axis direction of the crushing roller 12 .

The control mechanism 5 includes a nut 51, which is located directly above the guide rod 45, and the nut 51 can reciprocate along the guide rod 45;

Specifically, the control mechanism 5 also includes a reciprocating screw 53, and the nut 51 is sleeved on the reciprocating screw 53. The reciprocating screw 53 is a screw that can enable the nut 51 to achieve reciprocating motion without changing the rotation direction. A through hole is opened on the nut 51, and a cross bar (not shown) fixed to the inside of the material receiving box 2 is passed through the nut 51. The reciprocating screw 53 and the matching nut 51 belong to the existing technology, and their principles are not repeated here.

One end of the reciprocating screw 53 extends out of the material receiving box 2, and a coaxial second sprocket 52 is fixedly set on the protruding end of the reciprocating screw 53. A crushing roller shaft 121 of one of the crushing rollers 12 extends out of the crushing box 1, and a coaxial first sprocket 122 is fixedly set on the protruding end of the crushing roller shaft 121. The two sprockets are driven by a chain. In this way, during crushing, the rotation of the crushing roller 12 can drive the continuous rotation of the reciprocating screw 53.

Furthermore, two vertical mounting plates 511 are provided at the bottom of the nut 51, an axis rod (not marked) is provided between the two mounting plates 511, a sleeve (not marked) is sleeved on the outer side of the axis rod, a vertical lever 512 is provided on the sleeve, a torsion spring (drawn) is provided in the sleeve, the torsion spring is sleeved on the axis rod, one leg of the torsion spring is connected to the axis rod, and the other leg of the torsion spring is connected to the inner wall of the sleeve, the bottom end of the lever 512 is lower than the top of the vertical section of the L-shaped rod 421 and the top of the vertical rod 431, and the lever 512 is in a vertical state when no force is applied.

Furthermore, as shown in FIG. 12 , a magnetic sheet 46 extending inward is disposed at the open end of the filter box 41 , and both the movable plate 42 and the grille 43 can be magnetically attracted to the magnetic sheet 46 .

When in use, as shown in FIG6 , in the filter box 41 on the left, the movable plate 42 is located on the left side of the opening 411, and the opening 411 is open, so that the gas in the receiving box 2 is filtered by the grille 43 and then discharged from the corresponding exhaust pipe 44, and the discharged gas is sent to the bag filter. In the filter box 41 on the right, the movable plate 42 is located at the left end and is adsorbed by the corresponding magnetic sheet 46, and the opening 411 in the filter box 41 is blocked;

At the same time, the lever 512 is located on the left side and is moving to the right side. When the lever 512 passes the L-shaped rod 421 on the left side, it pushes it to the right. When the vertical section of the L-shaped rod 421 moves to the right end of the corresponding bar hole 412, the movable plate 42 on the left side moves to the right side of the corresponding opening 411, and is magnetically attracted by the corresponding magnetic sheet 46, and the corresponding opening 411 is also blocked. The lever 512 bends and passes over the vertical section of the L-shaped rod 421. Then, under the action of the torsion spring, the lever 512 returns to the vertical state, which is the situation shown in FIG. 7 .

Further, the lever 512 continues to move rightward, and pushes the grille 43 to the right by driving the vertical rod 431. The magnetic force of the magnetic sheet 46 should be small, so that the vertical rod 431 can push the grille 43 away from the magnetic sheet 46. Then, as the lever 512 continues to move rightward with the grille 43, the grille 43 abuts against the open end of the right filter box 41 and is adsorbed on the corresponding magnetic sheet 46, forming the state of FIG. 8.

Then, as shown in FIG. 9 , the lever 512 bends and passes over the vertical rod 431, continues to move rightward and returns to a vertical state, then moves to the right L-shaped rod 421 and drives it to move rightward. When the vertical section of the right L-shaped rod 421 moves to the right end of the corresponding strip hole 412, the opening 411 of the right filter box 41 is opened, and the airflow enters the opening 411 through the left side of the grille 43 and is discharged from the corresponding exhaust pipe 44. The large volume of debris originally attached to the right side of the grille 43 is taken away by the airflow at this time and discharged from the exhaust pipe 44.

Afterwards, due to the limitation of the bar-shaped hole 412, the lever 512 bends and passes over the vertical section of the right L-shaped rod 421, that is, the state of FIG. 10 is changed to the state of FIG. 11;

After that, when the lever 512 moves to the right end of the stroke of the reciprocating screw 53 and starts to move to the left, similar to the above, the lever drives the right L-shaped rod 421 to move to the left to close the right opening 411, and then drives the grille 43 to move to the left to fit the open end of the left filter box 41, and then drives the left L-shaped rod 421 to move to the left to open the left opening 411, returning to the state shown in FIG. 6, and then the lever 512 continues to move to the left until the end of the stroke of the left side of the reciprocating screw 53;

In this way, automatic cleaning of the grille 43 can be achieved. Preferably, taking Figure 5 as an example, the right stroke end of the reciprocating screw 53 or the nut 51 should be as close as possible to the right end of the right filter box 41 to reduce the opening time of the opening 411 of the right filter box 41 as much as possible.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
