Description

Technical Field

[0001] This utility model relates to the field of waste recycling equipment, and in particular to a recycling equipment for waste materials. Background Technology

[0002] A large amount of waste is generated in production and daily life. Most of the waste still has recycling value, so it needs to be recycled. The main recycling method is to use crushing equipment to break it down so that useful materials can be screened out.

[0003] Existing methods use pusher plates to screen crushed waste materials. For example, Chinese utility model patent CN219766033U discloses a concrete waste recycling and screening device, which includes a box and at least two layers of pusher plates installed on the inner wall of the box. The diameter of the pusher plates decreases from top to bottom. The side wall of the box has a side discharge port. One end of the pusher plate is rotatably installed on the inner wall of the box, and the movable end extends beyond the side discharge port. The box is equipped with a drive mechanism for driving the movable end of the pusher plate to rise and fall and vibrate. This device has the effect of multi-stage screening, improving screening efficiency and reducing blockage.

[0004] The above-mentioned concrete waste recycling screening device screens the waste through a pusher plate. However, by setting the pusher plate at an angle, the waste rolls on the pusher plate for screening, which can easily lead to material accumulation and insufficient screening of the waste.

[0005] The existing method involves placing the pusher plate horizontally and shaking it to fully screen the waste. While this can increase the screening effect, the waste located on top of the pusher plate needs to be cleaned after screening. Utility Model Content

[0013] Optionally, the reciprocating mechanism includes a half gear, a moving frame, a second telescopic rod, a second reciprocating sleeve, a second reciprocating rod, a drive motor, and a reciprocating mechanism housing. The half gear is located in the middle of the reciprocating mechanism and is connected to the drive motor.

[0017] (III) Beneficial Effects

[0018] This utility model provides a recycling device for waste materials. It has the following advantages: by setting a screening mechanism at the bottom of the crusher, the crushed waste material is screened, and the insufficiently crushed waste material is screened. The insufficiently crushed waste material screened is lifted to the feed inlet of the crusher for further crushing by a return plate connected to the screening mechanism and the lifting mechanism, so as to achieve the purpose of full crushing.

[0019] The screening mechanism is equipped with a pusher plate and a screen plate. The screen plate is set horizontally and vibrates by a vibration motor to ensure sufficient screening of waste. The pusher plate is equipped with a screen bar inside and is controlled to move back and forth by a reciprocating mechanism. The pusher plate is guided and limited by a groove. When the pusher plate moves to the left, the pusher plate limit block slides to the left along the second transverse groove, causing the screen bar to push the waste on the top of the screen plate to the left and flatten the waste to prevent waste from accumulating and affecting the screening effect. When the pusher plate moves to the right, the pusher plate limit block slides to the right along the first transverse groove, causing the pusher plate to reset to the right and start the next pushing action.

[0020] By setting a left limiting mechanism on the left side of the pusher plate, the stability of the pusher plate's left and right movement is ensured. A pusher plate limiting block is set at the rear, so that the pusher plate limiting block moves along a quadrilateral in the groove, allowing the pusher plate to continuously push the insufficiently crushed waste material to the return plate.

[0034] Please see Figure 6This utility model provides a recycling device for waste materials.

When the pusher plate limiting block 333 slides to the step at the connection between transverse groove 363 and inclined groove 362, the spring 332 in the circular groove expands and pushes the pusher plate limiting block 333 out into transverse groove 364, so that the movement trajectory of the pusher plate 33 is within the groove 36, and the pusher plate 33 is prevented from reversing.

[0035] Please see Figure 1 and Figure 5 This utility model provides a recycling device for waste materials. The reciprocating mechanism 37 includes a half gear 371, a moving frame 372, a second telescopic rod 373, a second reciprocating sleeve 374, a second reciprocating rod 375, a drive motor 376, and a reciprocating mechanism housing 377. The half gear 371 is provided in the middle of the reciprocating mechanism 37, and the half gear 371 is connected to the drive motor 376.

The reciprocating rod 375 is slidably connected to the reciprocating sleeve 374. The left side of the reciprocating sleeve 374 is fixedly connected to the right end of the pusher plate 33. The drive motor 376 drives the half gear 371 to rotate. The half gear drives the moving frame 372 to move left and right. The retraction rod 373 at the right end of the moving frame 372 moves left and right on the reciprocating mechanism housing 377, restricting the movement trajectory of the moving frame 372. The reciprocating rod 375 above the moving frame 372 pushes the reciprocating sleeve 374, causing the pusher plate 33 connected to the left end of the reciprocating sleeve 374 to move left and right.

[0036] The working principle is as follows:

[0037] 1. Workers pour the waste material to be crushed into the feed inlet 11 of the crusher. The crusher crushes the waste material, and the crushed waste material is discharged from the discharge outlet 12 of the crusher and enters the feed inlet 21 of the pulverizer 2. The pulverizer 2 pulverizes the crushed waste material into fine particles, and the pulverized waste material is discharged from the discharge outlet 22 of the pulverizer and enters the screening mechanism 3. When the screening mechanism 3 is working, the drive motor 376 drives the half gear 371 in the reciprocating mechanism 37 to rotate. The rotating half gear 371 drives the moving frame 372 to move left and right, causing the reciprocating rod 375 fixed on the moving frame 372 to move left and right. The reciprocating rod 375 pushes against the pusher plate 33. The reciprocating sleeve 374 moves left and right, thereby driving the pusher plate 33 to move. The pusher plate 33 is guided and limited by the groove 36. When the pusher plate 33 moves to the left, the pusher plate limiting block 333 of the pusher plate 33 slides to the left along the transverse groove 363, causing the screening rod 331 to push the waste at the top of the screen plate 34 to the left, and also has a flattening effect on the waste, preventing the waste from accumulating and affecting the screening effect. When the pusher plate limiting block 333 slides to the left end of the transverse groove 363, the pusher plate limiting block 333 slides to the upper left along the inclined groove 364, driving the pusher plate 33 to rise, preventing the screen rod 331 from pushing the waste back to the right when the pusher plate 33 returns to the right for the next push. Simultaneously, the spring 332 inside the pusher plate's circular groove is compressed. When the pusher plate limiting block 333 moves to the junction of the inclined groove 364 and the transverse groove 361, the pusher plate 33 continues to move to the left. The pusher plate limiting block 333 slides to the left end of the transverse groove 361, and is pushed out by the spring 332, entering the transverse groove 361. Subsequently, the reciprocating mechanism 37 drives the pusher plate 33 to move to the right. The pusher plate limiting block 333 slides to the right along the transverse groove 361. When the pusher plate limiting block 333 slides to the right end of the transverse groove 361, it slides into the inclined groove 362, driving the pusher plate 33 to move to the lower right. When the spring 332 is compressed, and the pusher plate limit block 333 reaches the junction of the inclined groove 362 and the transverse groove 363, the pusher plate 33 continues to move to the right. The pusher plate limit block 333 slides to the right end of the transverse groove 363, and the pusher plate limit block 333 is pushed out by the spring 332 and enters the transverse groove 363. The pusher plate 33 resets and performs the next pushing action, screening the larger waste particles that cannot pass through the screen plate 34 to the return plate 38. At the same time, the vibrating motor vibrates the screen plate 34, allowing the smaller waste particles to pass through the screen plate 34. Then, the waste is discharged through the discharge port 32 of the screening mechanism to the conveying mechanism 4. The conveying mechanism 4 conveys the screened waste to the outside for recycling.

[0038] 2. Larger waste particles are screened from the screening mechanism 3 to the return plate 38. The larger waste particles are poured into the hopper 51 of the lifting mechanism 5 through the return plate 38. Then, they are lifted to the top of the lifting mechanism 5 through the inside of the elevator and fall from the discharge port 52 above the lifting mechanism 5 into the crusher feed port 21 above the crusher 2. Then, they are crushed again by the crusher 3.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

The power supply is also common knowledge in the field.
