Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a crushing device for waste materials used in construction engineering. Background Technology

[0002] Crushing devices, such as dual-stage crushers, effectively pulverize construction waste through two sets of crushing components, improving processing efficiency. They can handle construction waste of different hardness and size, such as concrete and bricks, and are widely used. These crushing devices play a key role in construction waste treatment, helping to achieve the harmlessness, reduction, and resource utilization of construction waste.

[0003] An existing construction waste crushing device (announcement number: CN216965762U) has at least the following drawbacks: the materials, volumes, and weights of construction waste vary, but the waste needs to be fed into the crusher after it has been running. However, if the feed opening is open, the crushed waste fragments are likely to fly out of the crusher and cause accidental injury to nearby workers. If the feed opening is partially covered, it is not conducive to the entry of larger waste materials into the crusher for crushing. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste crushing device for construction engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste crushing device for construction projects includes a crushing box, a storage box, and a folding cover. A hopper is fixedly connected to the top of the crushing box, and the storage box is fixedly connected to one side of the hopper. The folding cover is located on the top of the hopper. A first cover and a second cover are provided on one side of the folding cover. The two ends of the second cover are rotatably connected to the groove of the first cover. An electric shaft assembly is fixedly connected to both ends of the folding cover. The electric shaft assembly includes a drive motor and a shaft column. The drive motor is fixedly connected to the outside of the storage box, and one end of the shaft column is fixedly connected to the output end of the drive motor. The shaft column passes through the storage box and is fixedly connected to the folding cover. The second cover is rotatably connected to the groove on the other side of the folding cover through the electric shaft assembly. A baffle is fixedly connected to the top of the side of the folding cover closest to the storage box.

[0007] As a further embodiment of this utility model, a magnet is fixedly connected to the side of the second cover away from the first cover, a baffle is fixedly connected to the top of the side of the first cover near the folding cover, and handles are fixedly connected to both sides of the folding cover, the first cover and the second cover.

[0008] As a further embodiment of this utility model, a crusher is fixedly installed inside the crushing box. The crusher is located at the bottom of the hopper, and a baffle plate is provided at the bottom of the crusher.

[0009] As a further embodiment of this utility model, a vibrating screen plate is provided at the bottom of the baffle plate, the vibrating screen plate is fixedly connected to the inner wall of the crushing box in an inclined manner, and a first vibrating screen motor and a second vibrating screen motor are fixedly connected to the outer side of the crushing box.

[0010] As a further embodiment of this utility model, the first vibrating screen motor is located on top of the second vibrating screen motor, and the inside of the crushing box is divided into a feeding bin by a vibrating screen plate. The bottom of the feeding bin is inclined and located at the bottom of the vibrating screen plate.

[0011] As a further embodiment of this utility model, a side discharge port is provided on one side of the outside of the crushing box, the side discharge port is located on one side of the vibrating screen plate, and a discharge port is provided through the bottom of the crushing box, the discharge port being connected to the discharge bottom hopper.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the volume of waste material being fed is small, the worker opens the second cover by the handle. The shaft of the second cover rotates at one end of the first cover to open the hopper, facilitating the feeding of small materials. At the same time, it partially blocks the opening of the hopper to prevent material from splashing out. If the volume of waste material being fed is large, the worker manually opens the second cover, causing it to rotate and fold over the top of the first cover. Simultaneously, the magnet on the outside of the first cover adheres to the baffle plate on the top of the second cover, fixing the position of the first cover. The worker then activates several electric shaft groups. The electric shaft group between the folding cover and the first cover drives the shaft column to rotate through the drive motor, causing the first cover and the fixed second cover to rotate and fold over the top of the folding cover. The electric shaft group at the tail end of the folding cover drives the three-fold cover plate to stand upright in the storage box, fully opening the hopper for easy feeding of large waste materials. The opening of the hopper is adjusted by the continuous folding of the cover plate.

[0014] 2. The crusher has both fine and coarse screening functions. Waste materials enter the crushing chamber and are crushed by the crusher. When the first vibrating screen motor is started, it drives the baffle plate to vibrate, causing smaller pieces of waste material to pass through the baffle plate and enter the vibrating screen plate. At the same time, the crushed particles also fall with the pieces. Larger pieces continue to be crushed on the baffle plate. The second vibrating screen motor drives the vibrating screen plate to vibrate and finely screen the particles, causing the fine particles to fall into the bottom hopper. Both the vibrating screen plate and the bottom hopper are inclined. During the vibration, the vibrating screen plate causes smaller pieces to roll out of the side discharge port for discharge, while the particles slide out of the discharge port through the inclined bottom hopper for discharge. This process breaks large pieces of construction waste into smaller pieces and particles, facilitating subsequent transportation and recycling. Attached Figure Description

A hopper 101 is fixedly connected to the top of the crushing box 1. The storage box 2 is fixedly connected to one side of the hopper 101. The folding cover 4 is located on the top of the hopper 101. A first cover 5 and a second cover 6 are provided on one side of the folding cover 4. The two ends of the second cover 6 are rotatably connected to the groove of the first cover 5. Electric shaft assembly 3 is fixedly connected to both ends of the folding cover 4. The electric shaft assembly 3 includes a drive motor 301 and a shaft column 302. The drive motor 301 is fixedly connected to the outside of the storage box 2. One end of the shaft column 302 is fixedly connected to the output end of the drive motor 301. The shaft column 302 passes through the storage box 2 and is fixedly connected to the folding cover 4. The second cover 6 is rotatably connected to the groove on the other side of the folding cover through the electric shaft assembly 3. A baffle 401 is fixedly connected to the top of the side of the folding cover closest to the storage box 2.

[0024] When in use, if the volume of waste material being added is large, the operator manually opens the second cover 6, causing it to rotate and fold over the top of the first cover 5. At the same time, the magnet 601 on the outside of the first cover 5 attracts the top baffle 501 of the second cover 6, fixing the position of the first cover 5. The operator then activates several electric shaft groups 3. The electric shaft group 3 between the folding cover 4 and the first cover 5 drives the shaft column 302 to rotate via the drive motor 301, causing the first cover and the second cover 6 fixed in place to rotate and fold over the top of the folding cover 4 along with the shaft column 302. Meanwhile, the electric shaft group 3 at the tail end of the folding cover 4 drives the three-fold cover plate to stand upright inside the storage box 2, allowing the hopper 101 to open completely. The opening of the hopper 101 is adjusted by the continuously folding cover plate, facilitating the unloading of large waste materials.

[0025] In this embodiment, a magnet 601 is fixedly connected to the side of the second cover 6 away from the first cover 5, and a baffle 501 is fixedly connected to the top of the side of the first cover 5 near the folding cover 4. Handles 7 are fixedly connected to both sides of the folding cover 4, the first cover 5 and the second cover 6.

[0026] When in use, if the volume of the waste material being fed is small, the operator opens the second cover 6 through the handle 7. The shaft of the second cover 6 rotates at one end of the first cover 5 to open the feeding hopper 101, making it easier to feed small materials. At the same time, it partially blocks the opening of the feeding hopper 101 to prevent materials from splashing out of the feeding hopper 101. The folding cover 4 and the first cover 5 are rotatably connected by an electric shaft assembly 3. The drive motor 301 runs inside the folding cover 4, causing the output end of the drive motor 301 to drive the shaft column 302 to rotate, so that the first cover 5 follows the rotation of the shaft column 302 to fold.

[0027] In this embodiment, a crusher 8 is fixedly installed inside the crushing box 1. The crusher 8 is located at the bottom of the feeding hopper 101, and a baffle plate 9 is provided at the bottom of the crusher 8.

[0028] When in use, the crusher 8 has two functions: fine screening and coarse screening. Waste enters the crushing box 1 and is crushed by the crusher 8. The crusher 8 includes a motor and a shredder. The two shredders are driven by the motor in an alternating manner. The motor drives the shredders to rotate. The two shredders rotate counterclockwise and clockwise respectively to squeeze and crush the waste.

[0029] In this embodiment, a vibrating screen plate 10 is provided at the bottom of the baffle plate 9. The vibrating screen plate 10 is fixedly connected to the inner wall of the crushing box 1 in an inclined manner. A first vibrating screen motor 11 and a second vibrating screen motor 12 are fixedly connected to the outer side of the crushing box 1.

[0030] When in use, start the first vibrating screen motor 11 and the second vibrating screen motor. The first vibrating screen motor 11 drives the baffle plate 9 to vibrate, so that smaller pieces of waste material pass through the baffle plate 9 and enter the vibrating screen plate 10.

[0031] In this embodiment, the first vibrating screen motor 11 is located on top of the second vibrating screen motor 12. The crushing box 1 is divided into a feeding bottom chamber 102 by the vibrating screen plate 10. The bottom of the feeding bottom chamber 102 is inclined and located at the bottom of the vibrating screen plate 10.

[0032] During use, the crushed particles are fed along with the 12 crushed pieces, while the larger pieces continue to be crushed on the baffle plate 9. The second vibrating screen motor 12 drives the vibrating screen plate 10 to vibrate and finely screen the particles, so that the particles fall into the bottom hopper 102 through the vibrating screen plate 10. Both the vibrating screen plate 10 and the bottom hopper 102 are inclined.

[0033] In this embodiment, a side discharge port 13 is provided on one side of the outside of the crushing box 1. The side discharge port 13 is located on one side of the vibrating screen plate 10. A discharge port 14 is provided through the bottom of the crushing box 1. The discharge port 14 is connected to the discharge bottom hopper 102.

[0034] In use, both the vibrating screen plate 10 and the feeding hopper 102 are inclined. During the vibration process, the vibrating screen plate 10 drives the smaller pieces to roll out of the side discharge port 13 for feeding. The particles slide out of the feeding port 14 through the inclined feeding hopper 102 for feeding, thus breaking large pieces of construction waste into small pieces and particles, which is convenient for subsequent transportation and recycling.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the volume of the waste material being added is small, the worker opens the second cover 6 by using handle 7. The shaft of the second cover 6 rotates at one end of the first cover 5 to open the hopper 101, making it convenient for small materials to be fed. At the same time, it blocks part of the opening of the hopper 101 to prevent material from splashing out of the hopper 101. If the volume of the waste material being added is large, the worker manually opens the second cover 6, causing the second cover 6 to rotate and fold over the top of the first cover 5. At the same time, the magnet 601 on the outside of the first cover 5 attracts the baffle 501 on the top of the second cover 6, fixing the position of the first cover 5. The worker starts several electric shaft groups 3. The electric shaft group 3 between the folding cover 4 and the first cover 5 drives the shaft column 302 to rotate through the drive motor 301, causing the first cover and the second cover 6 fixed in place to rotate and fold over the top of the folding cover 4 along with the shaft column 302. The electric shaft group 3 at the tail end of the folding cover 4 drives the three-fold cover plate to stand upright in the storage box 2, so that the hopper 10 1. Fully open, the opening of the feed hopper 101 is adjusted by the continuously folding cover to facilitate the feeding of large waste materials. The crusher 8 has both fine and coarse screening functions. Waste materials enter the crushing box 1 and are crushed by the crusher 8. The first vibrating screen motor 11 and the second vibrating screen motor are started. The first vibrating screen motor 11 drives the baffle plate 9 to vibrate, so that smaller pieces of waste materials pass through the baffle plate 9 and enter the vibrating screen plate 10. At the same time, the crushed particles also follow the crushed pieces and are fed out, while larger pieces are fed through the baffle plate. The crushing process continues on the 9th stage. The second vibrating screen motor 12 drives the vibrating screen plate 10 to vibrate and finely screen the particles, causing the particles to fall into the feeding hopper 102 through the vibrating screen plate 10. Both the vibrating screen plate 10 and the feeding hopper 102 are inclined. During the vibration process, the vibrating screen plate 10 drives the smaller pieces to roll out of the side discharge port 13 for feeding, while the particles slide out of the feeding port 14 through the inclined feeding hopper 102 for feeding. This process breaks large pieces of construction waste into smaller pieces and particles, which is convenient for subsequent transportation and recycling.
