[0002] Solid waste crushers for environmental engineering are mechanical equipment specifically designed for environmental engineering projects. They can crush solid waste into smaller particles, which can then be more easily processed, such as recycled, landfilled, or incinerated. This type of equipment is commonly used in areas such as municipal solid waste treatment, industrial waste treatment, and resource recycling.

[0003] To facilitate feeding into the solid waste crusher, the feed inlet is usually left open. However, during the crushing process, due to mechanical forces, the material is torn, impacted, and ground, generating a large amount of fine dust. This dust can easily escape from the feed inlet, causing air pollution and reducing the quality of the workers' working environment. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A solid waste crusher for environmental engineering includes a crushing box 1, a top cover 11 rotatably connected to the surface of the crushing box 1, a feed hopper 12 fixedly connected to the surface of the top cover 11, a discharge port 13 at the bottom of the crushing box 1, and crushing rollers 14 rotatably mounted on the surface of the crushing box 1. One end of the crushing rollers 14 is equipped with a driving device, and the other end is equipped with a conveying device, thus ensuring that the two sets of crushing rollers 14 crush the solid waste through rotation. This technology is existing technology. A dust suppression mechanism is provided on the surface of the feed hopper 12, including a servo motor 2. A feed plate 21 is fixedly connected to the output shaft of the servo motor 2, and a partition 22 is rotatably connected inside the feed hopper 12. A spring 23 is fixedly connected to the surface of plate 22. The end of spring 23 away from partition plate 22 is fixedly connected to the inside of feed hopper 12. A stop rod 24 is fixedly connected to the inside of feed hopper 12. Strip-shaped dust collection shells 25 are fixedly installed on both sides of the top of feed hopper 12. An industrial vacuum cleaner 26 is installed at the output end of strip-shaped dust collection shells 25. This dust reduction mechanism covers the dust inside feed hopper 12 through feed plate 21 and partition plate 22 and guides the dust so that the dust can only be discharged from the top sides of feed hopper 12. Then, the strip-shaped dust collection shells 25 and industrial vacuum cleaner 26 are used to collect dust from the top of feed hopper 12, which greatly reduces the dust discharged from the top of feed hopper 12 and thus ensures the quality of the working environment.

[0024] Furthermore, an opening mechanism is provided on the surface of the crushing box 1. The opening mechanism includes a rotating rod 3, which is rotatably connected to the surface of the crushing box 1. A rotating bracket 31 is fixedly connected to the surface of the rotating rod 3. One side of the rotating bracket 31 is fixedly connected to the surface of the upper cover 11. An adjusting plate 32 is connected to the surface of the rotating bracket 31. An electric push rod 33 is rotatably connected to the surface of the crushing box 1. The piston rod of the electric push rod 33 is rotatably connected to the bottom of the adjusting plate 32. The crushing roller 14 inside the crushing box 1 needs to be maintained regularly. The opening mechanism can temporarily remove the upper cover 11 and the feed hopper 12 from the top of the crushing box 1, thereby facilitating the maintenance of the crushing roller 14 by the staff.

[0025] Furthermore, the feed plate 21 is in the shape of a cross. The servo motor 2 drives the feed plate 21 to rotate inside the feed hopper 12 through the output shaft. The feed plate 21 rotates to bring solid waste into the crushing box 1 through the feed hopper 12. During the rotation, the feed plate 21 is always shielded by the dust in the middle part of the feed hopper 12.

[0026] Furthermore, the push rod 24 is in the shape of a right triangle, and one end of the partition 22 is in contact with the bottom of the push rod 24 by rotation. At this time, the partition 22 is in a horizontal state, and the elastic force of the spring 23 acts on the partition 22. The solid waste is driven by gravity to rotate the partition 22 inside the feed hopper 12, thereby entering the crushing box 1 through the feed hopper 12. When the solid waste is not fed, the partition 22 is sealed at the bottom of the feed hopper 12 to prevent dust from escaping.

[0027] Furthermore, two sets of strip-shaped suction shells 25 are provided, located on both sides of the feed funnel 12 respectively. The length of the strip-shaped suction shells 25 is the same as the length of the feed funnel 12. The industrial vacuum cleaner 26 sucks dust through the strip-shaped suction shells 25 on both sides of the feed funnel 12. The bottom of the strip-shaped suction shells 25 is provided with strip-shaped suction slits to suck dust into the interior of the industrial vacuum cleaner 26 for easy cleaning. The continuous strip-shaped suction slits at the bottom of the strip-shaped suction shells 25 form a negative pressure adsorption band, which, together with the continuous suction of the industrial vacuum cleaner 26, can efficiently capture the dust that escapes from both sides of the feed funnel 12. The top of the strip-shaped suction shells 25 is sloping, which facilitates the entry of solid waste into the interior of the feed funnel 12.

[0028] Furthermore, the rotating support 31 is in an "L" shape. The rotating support 31 rotates on the crushing box 1 via the rotating rod 3. The rotating support 31 drives the upper cover 11 to rotate on the top of the crushing box 1, thereby opening the upper cover 11 and the feed hopper 12 on the top of the crushing box 1. A sealing strip is provided at the bottom of the rotating support 31. The sealing strip of the rotating support 31 can rotate to press against the surface of the crushing box 1, forming a seal between the crushing box 1 and the upper cover 11.

[0029] Furthermore, the adjusting plate 32 rotates on the surface of the crushing box 1 via the rotating bracket 31, and the electric push rod 33 drives the adjusting plate 32 to rotate on the top of the crushing box 1 via the piston rod. During the driving process, the electric push rod 33 rotates on the crushing box 1, thereby driving the adjusting plate 32 to rotate. The adjusting plate 32 drives the upper cover 11 to rotate via the rotating bracket 31, thereby moving the upper cover 11 and the feed hopper 12 to one side of the crushing box 1, which facilitates the maintenance of the crushing roller 14.

[0030] Working principle: The output shaft of the servo motor 2 drives the feed plate 21 to rotate. During the rotation of the feed plate 21, solid waste is introduced into the crushing box 1 through the feed funnel 12. During the introduction process, the solid waste is rotated by gravity, causing the partition 22 to rotate and enter the crushing box 1. When the solid waste is not being fed, the spring 23 will rotate the partition 22 to the bottom of the stop rod 24 through the elastic force to seal the dust. When the solid waste is being fed, the feed plate 21 can also seal the dust in the center of the feed funnel 12 during the rotation process. The dust that escapes from the sides of the feed funnel 12 is sucked up by the strip-shaped dust suction shell 25 in conjunction with the industrial vacuum cleaner 26, thereby reducing the dust discharged from the top of the feed funnel 12 and ensuring the quality of the working environment.

[0031] The top cover 11 rotates on the top of the crushing box 1 via the rotating rod 3 and the rotating bracket 31. The electric push rod 33 drives the adjusting plate 32 to rotate via the piston rod. The adjusting plate 32 drives the rotating bracket 31 to rotate. The rotating bracket 31 drives the top cover 11 and the feed hopper 12 to rotate to one side of the crushing box 1, making the crushing roller 14 on the crushing box 1 easier to maintain and improving the maintenance efficiency of the crushing roller 14.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
