[0002] A large metal crusher is a machine specially used to crush scrap metal materials. It can also be called a metal pulverizer. It has powerful crushing ability and high efficiency. It can quickly crush large metal materials into small pieces or granules for subsequent recycling, transportation and processing. When existing small and medium-sized large metal crushers crush metals, since the crusher uses two crushing rollers to shear and crush the metal, for some specific shapes, such as: too flat metal objects and metal materials with spherical outer surfaces, these shapes of metals will slide back and forth on the two crushing rollers after being fed into the metal crusher, and cannot be sheared immediately by the crushing rollers. These metals will reduce the working efficiency of the entire metal crusher. Therefore, it is of great significance to improve the crushing efficiency of large metal crushers for metals of different shapes. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] Example 1

[0020] Large metal crushers, such as Figure 1 As shown, it includes a crusher 1, a crushing roller 2 and a toggle assembly. A feed hopper 101 is installed on the top of the crusher 1. A crushing roller 2 for crushing large pieces of metal is arranged inside the crusher 1. The toggle assembly is symmetrically installed on the front and rear sides of the upper part of the crusher 1. The toggle assembly is used to toggle large pieces of metal that are difficult to be sheared by the crushing roller 2.

[0021] like Figure 1 and 2 As shown, the toggle assembly includes a bracket 3, a rotating shaft 4, a torsion spring 5, a toggle rod 6 and a handle 7. The bracket 3 is fixedly connected to the top right side of the crusher 1. The rotating shaft 4 is L-shaped. One end of the rotating shaft 4 is rotatably connected to the bracket 3, and the rotating shaft 4 passes through both sides of the feed hopper 101. The rotating shaft 4 is rotatably connected to the feed hopper 101. A torsion spring 5 is wound around one end of the rotating shaft 4. One end of the torsion spring 5 is fixedly connected to the rotating shaft 4, and the other end of the torsion spring 5 is fixedly connected to the feed hopper 101. The torsion spring 5 is located between the bracket 3 and the feed hopper 101. The toggle rod 6 is fixedly connected to the rotating shaft 4. The toggle rod 6 is comb-shaped, and the comb width is smaller than the distance between the two blades of the crushing roller 2. The toggle rod 6 is located inside the feed hopper 101, and the handle 7 is fixedly connected to the other end of the rotating shaft 4.

[0022] The staff first starts the crusher 1, and then puts the metal block to be crushed into the feed hopper 101. After the conventional large piece of metal enters the feed hopper 101, it is crushed by the crushing roller 2. When the metal entering the feed hopper 101 is flat or has a lot of curved surfaces, these unconventional metals will slide on the crushing roller 2 and have difficulty entering the crushing roller 2. At this time, the staff can turn the handle 7 in the corresponding direction according to the position of the unconventional metal, and the handle 7 drives the rotating shaft 4 to rotate. At this time, the torsion spring 5 is in a compressed state, and the rotating shaft 4 drives the toggle rod 6 to lift up. At this time, the toggle rod 6 is in contact with the unconventional metal. The toggle lever 6 changes the position of the unconventional metal so that the unconventional shaped metal that is more easily sheared enters between the two crushing rollers 2, so that the unconventional shaped metal entering the crusher 1 can be quickly crushed, thereby improving the crushing efficiency of the metal crusher 1. During the crushing process, the baffle 11 riveted on the feed hopper 101 can prevent the splashing of metal debris during the operation of the crusher 1, thereby improving the safety of the entire device during operation. At this time, the staff releases the handle 7, and the torsion spring 5 on the rotating shaft 4 is reset to restore the toggle lever 6 to its initial state. After the crushing is completed, the crusher is closed.

[0023] like Figure 1 and 3As shown, it also includes a pushing component, which includes a U-shaped push rod 8, a return spring 9 and an extrusion plate 10. The U-shaped push rod 8 is symmetrically slidably connected to the front and rear sides of the feed plate. The return spring 9 is symmetrically wound around the U-shaped push rod 8. One end of the return spring 9 is fixedly connected to the U-shaped push rod 8, and the other end of the return spring 9 is fixedly connected to the feed hopper 101. The extrusion plate 10 is fixedly connected to the U-shaped push rod 8, and the extrusion plate 10 is located inside the feed hopper 101.

[0024] like Figure 1 As shown, an anti-skid pad 12 is also included, and the anti-skid pad 12 is sleeved on the U-shaped push rod 8.

[0025] When a spherical object with a relatively smooth surface is put into the crusher 1, due to the small friction between the crushing roller 2 and the smooth spherical metal surface, these smooth spherical metals will stay on the front and rear sides of the feed hopper 101, and the blades of the crushing roller 2 cannot bring the smooth spherical metal into the central crushing area. At this time, the staff can push the U-shaped push rod 8 in the corresponding direction. An anti-slip pad 12 is added to the middle part of the U-shaped push rod 8, which increases the friction when the staff holds the U-shaped push rod 8. The U-shaped push rod 8 drives the extrusion plate 10 to move toward the central crushing area. At this time, the extrusion plate 10 can push the smooth spherical metal to move toward the central crushing area, thereby improving the crushing efficiency of the metal crusher 1 for the smooth spherical metal. After completing the operation, the operator releases the U-shaped push rod 8, and the U-shaped push rod 8 returns to its initial position under the action of the reset spring 9.

[0026] like Figure 1 As shown, a waste box 13 is also included, and the waste box 13 is slidably connected to the crusher 1.

[0027] During the crushing process, after the metal block entering the crusher is crushed by the crushing roller 2, the crushed metal debris will fall directly below the crusher 1. After the device completes its work, the staff will first close the crusher 1, pull out the waste box 13 from the bottom of the crusher 1, and after processing the metal debris in the waste box 13, put the waste box 13 into the crusher 1 again to restart the work. The waste box 13 can collect the metal debris during the operation of the crusher, so as to prevent the metal debris from falling directly into the working environment or the inside of the machine body.

[0028] like Figure 1 As shown, the crusher 1 also includes an adjusting foot 14 which is fixedly connected to the lower part of the crusher 1 .

[0029] In order to increase the adaptability of the device to work on uneven ground, four adjustment feet 14 are added to the bottom of the crusher 1. The staff can adjust the four feet to a suitable position so that the crusher 1 can maintain horizontal stability when the entire device works on uneven ground, thereby improving the adaptability of the device in an uneven working environment.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
