Description

Technical Field

[0001] This utility model relates to the field of construction waste unloading technology, specifically a construction waste unloading device. Background Art

[0002] Construction projects generate a large amount of slag, waste materials, and other waste. After construction, the waste needs to be transported from the construction site to the ground for disposal. However, construction waste occupies a lot of land, so it is crushed and then disposed of or reused depending on its properties. Since most construction waste is irregular in shape and size, the transport container can only carry a small amount of waste, resulting in low unloading efficiency. After being transported to the ground, it needs to be transported to a designated location for further crushing, which is a cumbersome process. In addition, when construction waste is screened to separate different sizes, some waste remains on the screen or screen plate, affecting the screening and collection efficiency after crushing. Therefore, this solution provides a construction waste unloading device. Utility Model Content

[0003] The purpose of this utility model is to provide a construction material unloading device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a construction material unloading device, comprising a movable box, a feeding hopper at the top of the movable box, a reciprocating telescopic motor on one side of the feeding hopper, a screen plate rotatably connected to one side of the inner top surface of the movable box via a hinge shaft, the bottom surface of the screen plate being connected to the inner wall of the movable box via an inclined spring, a vertical partition plate installed in the center of the interior of the movable box, a limit stop fixedly installed at the top of the partition plate via a support rod, two horizontally parallel crushing rollers installed on one side of the partition plate, a rotating roller drive motor connected to the back of the crushing rollers and located on the back of the movable box, with a gap between the two crushing rollers;

[0005] The bottom surface of the movable box is provided with two collection boxes, which are separated from each other by a partition plate. The two collection boxes are located at the bottom of the screen plate and the crushing roller, respectively. Two electric push rods are installed on the back of the movable box, and the ends of the two electric push rods pass through the movable box and face the back of the collection boxes. The electric push rods are protected by a protective shell.

[0006] Preferably, the front of the mobile container is provided with transparent glass, and two openings are provided at the bottom of the transparent glass, with the openings located on the front of the collection box.

[0007] Preferably, the end of the telescopic shaft of the reciprocating telescopic motor is located directly above the bottom of the inclined surface of the sieve plate.

[0008] Preferably, the inner wall of the mobile box is provided with a sloping guide plate, and the sloping guide plate is located at the back of the collection box.

[0009] Beneficial effects

[0010] This utility model provides a construction material unloading device, which has the following beneficial effects:

[0011] In this invention, construction waste can be fed into the mobile box from the hopper. After being crushed by the screen plate and crushing roller, the waste falls into two collection boxes. Then, the electric push rod pushes the corresponding collection boxes out of the mobile box. This provides convenience for unloading and transporting large-volume waste that is difficult to unload during construction, and avoids the drawback of construction waste remaining on the screen plate. This makes the collection of construction waste fall more smoothly and facilitates the unloading and transportation of construction waste. Attached Figure Description

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Please see Figure 1-3This utility model provides a technical solution: a construction material unloading device, including a movable box 1, a feeding hopper 2 at the top of the movable box 1, a reciprocating telescopic motor 3 on one side of the feeding hopper 2, a screen plate 5 rotatably connected to one side of the inner top surface of the movable box 1 through a hinge shaft 4, the bottom surface of the screen plate 5 being connected to the inner wall of the movable box 1 through an inclined spring member 6, a vertical partition plate 7 installed in the center of the interior of the movable box 1, a limit seat 8 fixedly installed at the top of the partition plate 7 through a support rod, two horizontally parallel crushing rollers 9 installed on one side of the partition plate 7, the bearings at the front end of the crushing rollers 9 being installed on the front inner wall of the movable box 1, a rotating roller drive motor 10 connected to the back of the crushing rollers 9, and the rotating roller drive motor 10 being located on the back of the movable box 1, with a gap between the two crushing rollers 9;

[0018] Two collection boxes 11 are provided on the bottom surface of the inside of the movable box 1. The two collection boxes 11 are separated from each other by a partition plate 7. The two collection boxes 11 are located at the bottom of the screen plate 5 and the crushing roller 9, respectively. Two electric push rods 12 are installed on the back of the movable box 1, and the ends of the two electric push rods 12 pass through the movable box 1 and face the back of the collection box 11. The electric push rods 12 are protected by a protective shell.

[0019] The front of the mobile box 1 is provided with transparent glass 13, and two openings 14 are provided at the bottom of the transparent glass 13. The openings 14 are located on the front of the collection box 11, which makes it easy to observe whether there is a lot of construction waste left on the sieve plate 5. The vibration of the sieve plate 5 is controlled manually by the reciprocating telescopic motor 3.

[0020] The end of the telescopic shaft of the reciprocating telescopic motor 3 is located directly above the bottom of the inclined surface of the sieve plate 5. That is, the end of the telescopic shaft of the reciprocating telescopic motor 3 is not fixedly connected to the sieve plate 5. Only when the sieve plate 5 needs to vibrate will the end of the telescopic shaft of the reciprocating telescopic motor 3 press down and swing the sieve plate 5.

[0021] An inclined guide plate 15 is provided on the inner wall of the movable box 1, and the inclined guide plate 15 is located at the back of the collection box 11, so that some large construction waste can smoothly slide into the collection box 11 after being crushed by two crushing rollers 9.

[0022] Working principle:

[0023] In this utility model structure, during actual use, construction waste is manually fed into the feed hopper 2. The construction waste first falls onto the screen plate 5 inside the movable box 1. A portion of the waste smaller than the aperture of the screen plate 5 falls directly into the collection box 11 on the left side of the partition plate 7. Another portion of the construction waste slides down the inclined screen plate 5 and falls onto the two crushing rollers 9. The two rotating roller drive motors 10 on the back of the movable box 1 drive the two crushing rollers 9 to rotate in opposite directions. The construction waste is crushed by the two crushing rollers 9. The crushed waste falls from the gap between the two crushing rollers 9. During the fall, it also slides down the inclined guide plate 15 and falls into the collection box 11 on the right side of the partition plate 7.

[0024] As the waste slides down the screen plate 5, some waste remains on the screen plate 5. At this time, the reciprocating telescopic motor 3 can be used to work. The telescopic shaft at the bottom of the reciprocating telescopic motor 3 extends downward and contacts the surface of the screen plate 5 until the screen plate 5 is pressed down. Then, the screen plate 5 is stopped by the limiting seat 8 at the top of the partition plate 7. The telescopic shaft is then controlled by the reciprocating telescopic motor 3 to retract upward. At this time, the surface of the screen plate 5 is no longer in contact with the telescopic shaft at the bottom of the reciprocating telescopic motor 3. The screen plate 5 will swing upward and reset under the action of the spring 6. The screen plate 5 achieves a vibration effect, so that the construction waste remaining on the screen plate 5 can slide down smoothly.

[0025] After the above steps, the construction waste falls into the two collection boxes 11 inside the mobile container 1. The two collection boxes 11 are pushed out from the opening 14 on the front of the mobile container 1 by the two electric push rods 12 on the back of the mobile container 1.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
