Description

Technical Field

[0001] This application relates to the technical field of separator feeders, and specifically to a multifunctional separator feeder for concrete. Background Art

[0002] A concrete separator is a device specifically used in construction sites and concrete production plants. Its main function is to separate solid particles (such as sand, stones, etc.) and liquids (such as water and cement slurry) in concrete. In the field of concrete processing, separators are widely used. The performance of the feeder directly affects the working efficiency and processing effect of the separator. Although the separator feeders on the market currently can meet the basic feeding requirements, there are still many deficiencies in terms of feeding uniformity, anti-blocking, and raw material pretreatment.

[0003] For example, the washable separator feeder disclosed in Chinese Patent Publication No. (CN217191227U), which relates to the technical field of concrete processing, improves the problem that workers need to hold a water pipe to wash the feeder, which is time-consuming and laborious. It includes a feeding trough, a discharge port, a housing, a washing pipe, and a nozzle. A screw is rotatably installed inside one of the housings, and a guide rod is fixedly installed inside the other housing. Both ends of the washing pipe are fixedly installed with a screw sleeve and a guide sleeve respectively. The screw sleeve is threadedly sleeved on the screw, and the guide sleeve is slidably sleeved on the guide rod. Through the settings of the washing pipe, the inlet hose, the nozzle, the screw, the guide rod, the screw sleeve, the guide sleeve, and the motor, after the work is completed, the motor can be started to drive the screw to rotate, so that the screw sleeve drives the washing pipe to move along the length direction of the screw, so that the washing pipe moves on the top of the feeding trough, thereby comprehensively washing the inside of the feeding trough without the need for workers to operate, saving time and effort.

[0004] However, in the prior art such as the above patent, the separator feeder usually adopts a single feeding port design. This design lacks flexibility and adjustment mechanisms and cannot adjust the feeding quantity and speed according to actual needs. In addition, the structures of these traditional feeders are relatively simple and do not integrate functions for pretreatment of raw materials such as screening and crushing. Therefore, the quality of the raw materials entering the separator cannot be effectively guaranteed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, this application provides a multifunctional separator feeder for concrete, which has advantages such as good feeding pretreatment effect, and solves the obvious limitations in the design of traditional separator feeders. The problems of uneven feeding and easy blockage seriously affect the working efficiency of the separator and increase the maintenance cost of the equipment. At the same time, due to the lack of an intelligent control system, the operation process is not only cumbersome but also easily affected by human factors, resulting in mistakes.

[0006] To achieve the above object, the present application provides the following technical solutions: A multi-functional separator feeder for concrete, including a feed box, wherein screening mechanisms are provided on the inner walls of the left and right sides of the feed box, and a crushing mechanism is provided on the inner wall of the feed box and below the screening mechanisms;

[0007] The screening mechanisms include two fixing plates, a number of vibration springs, two mounting frames, two connecting studs, a screen, two pressing plates, two locking nuts and a vibrating member.

The vibrating member is arranged between the inner walls of the left and right sides of the feed box to drive the screen to vibrate and screen. An inlet is provided on the upper surface of the feed box, and a feed hopper is fixed to the inner wall of the inlet.

[0008] By adopting this technical solution, a screening mechanism and a crushing mechanism are arranged in the feed box to realize the integration of material screening and crushing.

The driving motor is fixed to the left side of the feed box, and the outer side of the output shaft of the driving motor is fixed to the rotating shaft.

[0010] By adopting this technical solution, through the combination of the eccentric cam and the driving motor, the effective vibration of the screen is realized, and the screening effect is enhanced.

[0011] Further, the cross-sectional shape of the mounting frame is L-shaped, and the length of the pressing plate is equal to the length of the mounting frame.

[0012] By adopting this technical solution, the mounting frame with an L-shaped cross-section provides better stability and support, ensuring the smoothness of the screening process.

[0013] Further, mounting holes are respectively provided on the left and right sides of the upper surface of the screen, and the screen is slidably connected to the outer sides of the two connecting studs through the mounting holes.

[0014] By adopting this technical solution, the screen can be quickly slidably connected and replaced, improving the maintenance efficiency.

[0015] Furthermore, guard plates are fixed on all four sides of the upper surface of the screen mesh.

[0016] By adopting this technical solution, the guard plates on the upper surface of the screen mesh can extend the service life of the screen mesh.

[0017] Furthermore, the crushing mechanism includes a diversion cover, two support frames, four moving blocks, four hydraulic cylinders, two connecting shafts, two crushing rollers and two crushing motors. The diversion cover is fixed to the inner wall of the feed box and is located below the screen mesh. The two support frames are respectively fixed to the left and right sides of the feed box. The four moving blocks are respectively slidably connected between the upper and lower inner walls of the two support frames. The four hydraulic cylinders are respectively arranged on the left and right sides of the feed box, and the output shafts of the four hydraulic cylinders are respectively fixed to the outer sides of the four moving blocks. On the opposite sides of the left and right moving blocks, rotation holes are respectively formed.

The two crushing motors are respectively fixed to the outer sides of the two left moving blocks, and the outer sides of the output shafts of the two crushing motors are respectively fixed to the two connecting shafts.

[0018] By adopting this technical solution, the moving blocks and crushing rollers driven by the hydraulic cylinders achieve efficient crushing, adapt to materials with different hardnesses, and the adjustability of the distance between the crushing rollers enables the equipment to crush materials with different particle sizes according to needs.

[0019] Furthermore, a number of crushing teeth are fixed on the outer sides of the two crushing rollers. Adjusting openings are respectively formed on the left and right inner walls of the feed box, and the two connecting shafts are respectively slidably connected between the upper and lower inner walls of the two adjusting openings.

[0020] By adopting this technical solution, the crushing teeth on the crushing rollers enhance the crushing effect and improve the crushing quality of the materials.

[0033] Please refer to Figure 2 , for pre-feeding and separating the concrete entering the separator, the screening mechanism 2 in this embodiment includes two fixing plates 21, a number of vibrating springs 22, two mounting frames 23, two connecting studs 24, a screen 25, two pressing plates 26, two locking nuts 27, and a vibrating member 28. The two fixing plates 21 are respectively fixed to the inner walls of the left and right sides of the feeding box 1. A number of vibrating springs 22 are respectively fixed to the upper surfaces of the two fixing plates 21. The two mounting frames 23 are respectively fixed to the upper sides of the vibrating springs 22 on the left and right sides.

The screen 25 is slidably connected to the outer sides of the two connecting studs 24. The materials meeting the particle size requirements pass through the screen 25 and fall onto the crushing mechanism 3 or directly enter the next step of processing, while the larger materials remain on the screen 25 waiting for further processing. The two pressing plates 26 are respectively slidably connected to the outer sides of the two connecting studs 24 and are located above the screen 25. The two locking nuts 27 are respectively threadedly connected to the two connecting studs 24.

An inlet is opened on the upper surface of the feeding box 1, and a feeding hopper 29 is fixed to the inner wall of the inlet.

[0034] The vibrating member 28 includes a rotating shaft 281, two eccentric cams 282, and a driving motor 283. The rotating shaft 281 is rotatably connected between the inner walls of the left and right sides of the feeding box 1 through bearings. The two eccentric cams 282 are respectively fixed to the left and right sides of the outer surface of the rotating shaft 281 and are both located below the screen 25. The driving motor 283 is fixed to the left side of the feeding box 1, and the outer side of the output shaft of the driving motor 283 is fixed to the rotating shaft 281. The concrete raw materials enter the feeding box 1 through the feeding hopper 29. The driving motor 283 in the vibrating member 28 is started, driving the rotating shaft 281 to rotate, and then driving the eccentric cams 282 to generate vibrations. The vibrations are transmitted to the screen 25, causing the screen 25 to perform a vibrating and screening action to separate the large impurities and the materials with the required particle size in the raw materials.

When replacing the screen 25, before replacing the screen 25, ensure that the drive motor 283 of the screening mechanism 2 is turned off and locked to stop all vibration actions. Loosen the lock nut 27, then loosen the two pressing plates 26 on the screen 25, and remove the screen 25 from the connecting studs 24. Guard plates are fixed on all four sides of the upper surface of the screen 25. According to the required particle size requirements, select a suitable screen 25 and place it outside the connecting studs 24, ensuring that the screen 25 is correctly aligned and covers the entire screening area. Place the pressing plate 26 back on the screen 25 and fix it to the connecting studs 24 with the lock nut 27.

[0036] Please refer to Figures 3 to 4 For the purpose of crushing and conveying the screened concrete for use, the crushing mechanism 3 in this embodiment includes a diversion hood 31, two support frames 32, four moving blocks 33, four hydraulic cylinders 34, two connecting shafts 35, two crushing rolls 36, and two crushing motors 37. The diversion hood 31 is fixed to the inner wall of the feed box 1 and is located below the screen 25. The two support frames 32 are respectively fixed to the left and right sides of the feed box 1. The four moving blocks 33 are respectively slidably connected between the upper and lower inner walls of the two support frames 32. The four hydraulic cylinders 34 are respectively connected to the left and right sides of the feed box 1, and the output shafts of the four hydraulic cylinders 34 are respectively fixed to the outside of the four moving blocks 33. The distance between the crushing rolls 36 is adjusted by pushing the moving blocks 33 with the hydraulic cylinders 34. The crushed material is conveyed to the next process or storage through the discharge conveyor belt 38. Rotation holes are provided on the opposite sides of the left and right moving blocks 33. The two connecting shafts 35 are respectively rotatably connected to the inner walls of the two rotation holes through bearings. The two crushing rolls 36 are respectively fixed to the outside of the two connecting shafts 35 and are located between the left and right inner walls of the feed box 1. The material is crushed by the action of the crushing teeth between the two crushing rolls 36 to achieve the required particle size. According to the hardness of the material and the required particle size, the two crushing motors 37 are respectively fixed to the outside of the left two moving blocks 33, and the outside of the output shafts of the two crushing motors 37 are respectively fixed to the two connecting shafts 35, ensuring that after the concrete raw material is screened, the material suitable for entering the crushing mechanism 3 falls into the diversion hood 31 through the screen 25, and the crushing motors 37 are started to drive the connecting shafts 35 and the crushing rolls 36 to rotate.

[0037] In this embodiment, a number of crushing teeth are fixed to the outer sides of the two crushing rollers 36. Adjustment openings are formed in the left and right inner side walls of the feed hopper 1, and the two connecting shafts 35 are respectively slidably connected between the upper and lower inner side walls of the two adjustment openings. The process for adjusting the spacing between the crushing rollers 36 is as follows: Before adjusting the spacing between the crushing rollers 36, stop feeding materials into the crushing mechanism 3 to prevent material accumulation or equipment damage. Increase or decrease the spacing between the crushing rollers 36 as required. The inner bottom wall of the feed hopper 1 is fixed with a discharge conveyor belt 38, and a number of partition plates are fixed to the outer side of the discharge conveyor belt 38. By controlling the hydraulic oil flow rate of the hydraulic cylinder 34, the moving block 33 is pushed to move inwards or outwards. As the moving block 33 moves, the connecting shaft 35 and the crushing roller 36 will correspondingly adjust their positions, changing the spacing between the crushing rollers 36. Once the required spacing is reached, the position of the moving block 33 is fixed through the locking mechanism of the hydraulic system to ensure that the spacing does not change during the crushing process. After confirming that the adjustment is correct, restart the feeding system to start the crushing operation.

[0038] The working principle of the above embodiment is as follows:

[0039] (1) When pre-feeding and separating the concrete entering the separator, the concrete raw materials enter the feed hopper 1 through the feed hopper 29. The drive motor 283 in the vibrating member 28 is started, driving the rotating shaft 281 to rotate, and then driving the eccentric cam 282 to generate vibration. The vibration is transmitted to the screen 25, causing the screen 25 to perform a vibrating screening action to separate the large impurities and the materials of the required particle size in the raw materials. The materials meeting the particle size requirements pass through the screen 25 and fall onto the crushing mechanism 3 or directly enter the next step of processing, while the larger materials remain on the screen 25 waiting for further processing. When replacing the screen 25, before replacing the screen 25, ensure that the drive motor 283 of the screening mechanism 2 is turned off and locked to stop all vibrating actions. Loosen the locking nut 27, then loosen the two pressing plates 26 on the screen 25, and remove the screen 25 from the connecting stud 24. According to the required particle size requirements, select a suitable screen 25 and place it outside the connecting stud 24, ensuring that the screen 25 is correctly aligned and covers the entire screening area. Place the pressing plate 26 back on the screen 25 and fix it to the connecting stud 24 with the locking nut 27.

[0040] (2)When using the sieved concrete for crushing and conveying, ensure that after the concrete raw materials are sieved, the materials suitable for entering the crushing mechanism 3 fall into the guide cover 31 through the sieve mesh 25. Start the crushing motor 37 to drive the connecting shaft 35 and the crushing rollers 36 to rotate. The materials are crushed by the action of the crushing teeth between the two crushing rollers 36 to reach the required particle size. According to the hardness of the materials and the required particle size, the distance between the crushing rollers 36 is adjusted by pushing the moving block 33 with the hydraulic cylinder 34. The crushed materials are conveyed to the next process or storage by the discharge conveyor belt 38. The adjustment process of the distance between the crushing rollers 36: Before adjusting the distance between the crushing rollers 36, stop feeding materials into the crushing mechanism 3 to prevent material accumulation or equipment damage. Increase or decrease the distance between the crushing rollers 36 as needed. Push the moving block 33 inward or outward by controlling the hydraulic oil flow of the hydraulic cylinder 34. As the moving block 33 moves, the connecting shaft 35 and the crushing rollers 36 will adjust their positions accordingly, changing the distance between the crushing rollers 36. Once the required distance is reached, fix the position of the moving block 33 through the locking mechanism of the hydraulic system to ensure that the distance does not change during the crushing process. After confirming that the adjustment is correct, restart the feeding system to start the crushing operation.
