Description

Technical Field

[0001] This utility model relates to the technical field of construction waste recycling equipment, specifically a mobile construction waste crushing and recycling device. Background Technology

[0002] Construction waste refers to recyclable materials formed after buildings are demolished, including steel bars, concrete, stone, and soil.

[0003] After the demolition of buildings, the resulting construction waste needs to be recycled. The recycling process requires crushing and screening, which necessitates the use of crushers and screening machines. Existing equipment for crushing construction waste includes jaw crushers and hammer crushers.

[0004] However, most crushers and screening machines are not mobile. When carrying out recycling operations, the construction waste to be recycled needs to be transported to the crusher and screening machine. When the amount of construction waste is large, it is difficult to move the construction waste, and large crushers are too big to be moved.

[0005] To address this, a mobile construction waste crushing and recycling device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a mobile construction waste crushing and recycling device. By setting a base frame, wheels, and an upper frame, the crusher is installed on the upper frame, and the wheels are rotated and installed on the base frame, so that the whole device has mobility, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile construction waste crushing and recycling device includes a base frame, wheels, a crusher, and a drive motor. An upper frame is also fixedly installed on the top of the base frame. The wheels are installed on the base frame. The crusher and the drive motor are both installed on the upper frame. A pulley is provided on the side of the crusher. The wheels are rotatably mounted on the base frame. A screening device is provided on the base frame and is located below the crusher.

[0009] Specifically, the crusher is a small hammer crusher, and a pulley is fixedly installed on the output shaft of the drive motor. The pulley of the crusher and the pulley on the drive motor are linked by a belt. The drive motor is a 30 kW DC motor.

[0010] Preferably, the screening device includes a mounting bar, a crossbar, a vibrating motor, and a support plate. The crossbar is installed on the inner side wall of the upper frame, the support plate is installed on the crossbar, a screen is fixedly installed on the support plate, and a vibrating motor is fixedly installed on the side of the support plate away from the screen.

[0011] Specifically, the vibration motor is selected as a small-to-medium-sized YZO series motor. When the vibration motor is powered on, it generates a constantly changing thrust, which causes the support plate to generate a high-frequency, constantly changing thrust, causing the screen to vibrate at a high frequency.

[0012] Preferably, the mounting strip has a groove, the end of the support plate is slidably mounted on the groove, multiple springs are fixedly connected to the crossbar, multiple first columns are provided at the top of the crossbar, and multiple second columns are provided at the bottom of the support plate, with the first and second columns located inside the springs.

[0013] Preferably, a support leg is fixedly installed at the bottom of the end of the base frame away from the wheel, and the length of the support leg is less than the radius of the wheel.

[0014] Preferably, a handle is fixedly installed on the side wall of the base frame, and an anti-slip sleeve is fitted onto the handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The system includes a base frame, crusher, drive motor, and screening device. The drive motor rotates the crusher via a belt, and wheels are mounted on the base frame. Two wheels are positioned diagonally below the crusher, providing primary gravity support. Handles are fixedly connected to the side wall of the base frame, and anti-slip sleeves are fitted to the handles to prevent slippage. The screening device is located on the base frame and is used to screen the crushed material. This configuration combines mobility and screening functions into one unit, solving the problem of traditional crushing and screening devices being unable to move.

[0017] 2. The screening device includes a vibrating motor, a support plate, and a screen. The vibrating motor generates vibration, which drives the support plate and screen to shake at a high frequency. The crushed construction waste falls onto the screen. Small particles fall through the fine holes of the screen to the bottom of the screen, while larger particles slide to the other end of the screen, thus completing a pre-screening. This device integrates crushing and screening functions, resulting in high crushing and screening efficiency. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 3 This utility model provides a mobile construction waste crushing and recycling device, the technical solution of which is as follows:

[0024] A mobile construction waste crushing and recycling device includes a base frame 1, wheels 2, a crusher 3, and a drive motor 4. An upper frame 5 is fixedly installed on the top of the base frame 1. The wheels 2 are mounted on the base frame 1. The crusher 3 and the drive motor 4 are both mounted on the upper frame 5. A horizontal plate 7 is provided on the upper frame 5. The drive motor 4 is mounted on the horizontal plate 7. A pulley 11 is provided on the side of the crusher 3. The wheels 2 are rotatably mounted on the base frame 1. A screening device is provided on the base frame 1. The screening device is located below the crusher 3. The bottom of the crusher 3 is the discharge port.

[0025] The crusher 3 is a small hammer crusher 3 that is already available on the market. A pulley 11 is fixedly installed on the output shaft of the drive motor 4. The pulley 11 of the crusher 3 and the pulley 11 on the drive motor 4 are linked by a belt. The power of the drive motor 4 is a 30 kW DC motor.

[0026] like Figure 2 As shown, the screening device includes mounting strips 13, crossbars 15, a vibrating motor 16, and support plates 8. The mounting strips 13 are fixedly mounted on the inner side wall of the upper frame 5 by bolts. There are two mounting strips 13 and two support plates 8, which are symmetrically arranged. The bottom of the support plate 8 is provided with a flange, and multiple threaded holes are opened on the flange. A screen 10 is fixedly mounted on the flange by bolts. The support plate 8 is provided with multiple threaded holes, and the vibrating motor 16 is fixedly mounted on the support plate 8 through the threaded holes.

[0027] The mounting strip 13 has a groove, and the end of the support plate 8 has a T-shaped locking block that fits into the groove, allowing the support plate 8 to move along the direction restricted by the groove. The horizontal strip 15 is vertically and fixedly connected to the mounting strip 13. Multiple springs 14 are fixedly connected to the horizontal strip 15. Multiple first columns 18 are also provided at the top of the horizontal strip 15, and multiple second columns 19 are provided at the bottom of the support plate 8. The first and second columns 19 are located inside the springs 14, and the bottom of the support plate 8 is fixedly connected to the top of the springs 14.

[0028] The vibratory motor is a small to medium-sized YZO series motor. When energized, the vibratory motor generates a constantly changing thrust, which in turn causes the support plate 8 to produce a high-frequency, constantly changing thrust. This causes the screen 10 to vibrate at a high frequency. The crushed material falls onto the screen 10; fine particles fall through the screen 10 downwards, while coarser particles slide down the screen 10 to the other side. This process allows for a preliminary screening of the crushed construction waste material.

[0029] like Figure 1 As shown, a support leg 9 is fixedly installed at the bottom of the base frame 1 away from the wheel 2, and the length of the support leg 9 is less than the radius of the wheel 2. This allows the screen 10 to be tilted when the entire device is placed on the ground, so that the material blocked by the screen 10 after crushing can slide off from one side of the screen 10.

[0030] A handle 6 is fixedly installed on the side wall of the base frame 1. An anti-slip sleeve 12 is fitted onto the handle 6. When it is necessary to move the entire device, the operator can lift the device by holding the anti-slip sleeve 12.

[0031] Working principle: A small hammer crusher 3 is used to crush construction waste materials to obtain finer particles. A vibrating motor 16 drives the support plate 8 and the screen 10 to form a high-frequency shaking. After the crushed raw materials fall onto the screen 10, the fine particles fall directly below the screen 10, while the larger particles slide to the other side of the screen 10, thus completing the pre-screening of the raw materials.

[0032] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
