Description

Technical Field

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

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during the production activities of the construction industry, such as demolition, construction, decoration, and repair. Crushing equipment is mainly used to crush waste materials such as concrete blocks, bricks, and stones to facilitate subsequent recycling or to make them easier to process and transport.

[0003] Traditional crushing devices typically use internal crushing rollers to crush stones. However, a single crushing roller setup has the following drawbacks:

[0004] 1. Relying solely on crushing rollers may result in some materials not being fully crushed, especially for construction waste with high hardness (such as concrete blocks, bricks, etc.), which can easily produce large residual particles.

[0005] 2. When crushing materials with high hardness, relying solely on the crushing roller may accelerate the wear of the equipment, especially for the parts that directly contact the material (such as the roller surface), which may lead to increased maintenance costs. Utility Model Content

[0006] In order to overcome the shortcomings of traditional crushing devices that rely solely on crushing rollers for crushing operations and are prone to insufficient crushing, the technical problem to be solved is to provide a construction waste crushing device for construction.

[0007] The technical solution is as follows: A construction waste crushing device includes a frame, a cover, a feeding frame, a crushing component, liners, a shifting frame, a second motor, and a screening component. The frame is connected to both the left and right sides of the cover. The feeding frame is connected to and communicates with the top of the cover. The crushing component is installed on the feeding frame. Multiple liners are connected at intervals to both sides of the inner side wall of the cover. The second motor is installed on the upper side of the frame on the right side. The output shaft of the second motor passes through from the right side of the cover to the left side. The shifting frame is connected to the output shaft of the second motor. The shifting frame is located inside the cover. The screening component is installed at the bottom of the cover.

[0008] Furthermore, the crushing assembly includes a first motor, an input gear, an output gear, and crushing rollers. The first motor is installed on the right side of the feed frame, and the input gear is connected to the output shaft of the first motor. Crushing rollers are symmetrically rotated inside the feed frame, and the two crushing rollers mesh with each other. The output gear is connected to the right side of the front crushing roller, and the output gear meshes with the input gear.

[0009] Furthermore, the screening assembly includes a hopper, a screen, a corrugated rubber sleeve, and a shaking component. The hopper is slidably connected to the bottom of the machine cover. The corrugated rubber sleeve is connected to the bottom of the machine cover outside the hopper. The screen is connected to the bottom of the corrugated rubber sleeve. The hopper is connected to the screen via connecting rods extending from both sides. The holes on the hopper are the same size as the holes on the screen. Both sides of the screen are slidably connected to the frame on the same side. A shaking component is provided on the output shaft of the second motor.

[0010] Furthermore, the shaking assembly includes a cam, a push rod, a guide rod, and a return spring. Cams are connected to both sides of the output shaft of the second motor. The cams are located on both sides of the machine cover. Protrusions are spaced apart along the circumference of the cam. Push rods are connected to both sides of the top of the screen. The push rods contact and cooperate with the protrusions of the cams. Guide rods are connected to the lower side of the machine frame. The screen is slidably connected to the guide rods. Return springs are connected between the screen and the machine frame on the same side. The return springs are sleeved on the guide rods.

[0011] Furthermore, it also includes a DC fan and a discharge pipe. A DC fan is installed on the lower front side of the feeding frame, and the DC fan is connected to the feeding frame. A discharge pipe is connected to the lower rear side of the feeding frame.

[0012] Furthermore, filter plates are installed at the connection points between the DC blower and the feed frame, as well as at the connection points between the discharge pipe and the feed frame, to block stones.

[0013] Beneficial effects: 1. The crushing roller performs the initial crushing of the stones, and then the agitator moves the incompletely crushed stones to the liner plate. The stones are then crushed by knocking and colliding with each other, which ensures the uniformity of the particle size of the material and significantly improves the overall crushing effect.

[0014] 2. By using a DC fan in conjunction with a material discharge pipe, dust generated during the crushing process can be effectively collected, thereby avoiding excessive dust in the working environment and improving the quality of the working environment;

[0015] 3. The cooperation mechanism between the cam and the push rod can make the hopper and the screen shake up and down, so as to make the crushed stones be discharged faster, prevent the blockage, and at the same time play a buffering role to protect the equipment from excessive impact.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example: A construction waste crushing device for construction, such as Figures 1-4 As shown, the machine includes a frame 1, a cover 2, a feed frame 3, a crushing component, liners 9, a churning frame 10, a second motor 11, and a screening component. The cover 2 is connected to the frame 1 on both the left and right sides. The top of the cover 2 is connected to and communicates with the feed frame 3, which is equipped with the crushing component. Multiple liners 9 are connected at intervals on the front and rear side walls inside the cover 2. The second motor 11 is bolted to the upper side of the frame 1 on the right side. The output shaft of the second motor 11 passes through from the right side to the left side of the cover 2. The output shaft of the second motor 11 is connected to the churning frame 10, which is used to agitate stones that have not been crushed sufficiently. The churning frame 10 is located inside the cover 2. The bottom of the cover 2 is equipped with a screening component.

[0023] like Figure 1 As shown, the crushing assembly includes a first motor 4, an input gear 5, an output gear 51, and a crushing roller 6. The first motor 4 is bolted to the right side of the feed frame 3. The input gear 5 is connected to the output shaft of the first motor 4. The crushing roller 6 for crushing stones is symmetrically rotated inside the feed frame 3. The two crushing rollers 6 mesh with each other. The output gear 51 is connected to the right side of the front crushing roller 6. The output gear 51 meshes with the input gear 5.

[0024] like Figures 3-4 As shown, the screening assembly includes a hopper 16, a screen 15, a pleated rubber sleeve 17, and a shaking assembly. The hopper 16 for screening stones is slidably connected to the bottom of the machine cover 2. The pleated rubber sleeve 17 is connected to the bottom of the machine cover 2 outside the hopper 16. The screen 15 for buffering stones is connected to the bottom of the pleated rubber sleeve 17. The hopper 16 is connected to the screen 15 through connecting rods extending on both sides. The holes on the hopper 16 are the same size as the holes on the screen 15. The left and right sides of the screen 15 are slidably connected to the frame 1 on the same side. The shaking assembly is provided on the output shaft of the second motor 11.

[0025] like Figures 3-4 As shown, the shaking assembly includes a cam 12, a push rod 13, a guide rod 14, and a return spring 141. The output shaft of the second motor 11 is connected to the cam 12 on both the left and right sides. The cam 12 is located on both sides of the machine cover 2. The cam 12 has protrusions spaced around its circumference. The top of the screen 15 is welded to the left and right sides. The push rod 13 contacts and engages with the protrusions of the cam 12. The lower inner side of the frame 1 is welded to the guide rod 14. The screen 15 is slidably connected to the guide rod 14. The screen 15 is connected to the frame 1 on the same side, and the return spring 141 is sleeved on the guide rod 14.

[0026] like Figure 1 As shown, it also includes a DC fan 7 and a discharge pipe 8. A DC fan 7 for drawing air is installed on the lower front side of the feed frame 3. The DC fan 7 is connected to the feed frame 3. A discharge pipe 8 for collecting dust is connected to the lower rear side of the feed frame 3. Filter plates are provided at the connection points between the DC fan 7 and the feed frame 3, as well as between the discharge pipe 8 and the feed frame 3, to block stones and prevent stones from entering the DC fan 7 and the discharge pipe 8.

[0027] When crushing waste materials such as concrete blocks, bricks, and stones, the stones are placed in the feed frame 3, and the first motor 4 is started. The output shaft of the first motor 4 rotates, and the input gear 5 and output gear 51 mesh with each other to drive the two crushing rollers 6 to rotate, thus crushing the stones. At the same time, the DC fan 7 is started to blow air into the feed frame 3, blowing the dust generated by crushing into the discharge pipe 8. A cloth bag is connected to the discharge pipe 8 to collect the dust, while the air can be discharged through the cloth bag, thus avoiding a large amount of dust accumulating in the working environment. The crushed stones fall into the machine cover 2. The fully crushed stones can fall directly onto the screen 15 through the discharge hopper 16 and then be discharged through the screen 15, while the remaining stones remain in the machine cover 2. Then, the second motor 11 is started, and the output shaft of the second motor 11 rotates, driving the actuating frame 10 to rotate. The stones inside the motor housing 2 are struck against the liner 9, thus undergoing secondary crushing until they can pass through the holes in the hopper 16. The output shaft of the second motor 11 rotates, driving the cam 12 to rotate. The cam 12, through its protrusion, engages with the push rod 13, causing the push rod 13 to vibrate repeatedly up and down along the guide rod 14 due to the deformation of the return spring 141. This, in turn, causes the hopper 16 and the screen 15 to vibrate up and down. The corrugated rubber sleeve 17 is elastic and expands and contracts with the screen 15. The vibration of the hopper 16 and the screen 15 prevents stones from clogging the holes. The holes in the hopper 16 and the screen 15 are the same size, allowing stones to fall onto the screen 15 and be discharged through the screen's buffer. The corrugated rubber sleeve 17 can block some dust, preventing excessive dust from being generated when stones fall. After finishing work, the relevant equipment can be turned off.

[0028] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
