Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand processing equipment, and in particular to a quartz sand feeding and screening device. Background Technology

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Quartz mines are widely distributed throughout China. Quartz sand is made from natural quartz ore, processed through crushing, screening, and washing after extraction from mines. It has a multi-faceted or spherical appearance, is pure white, and possesses high mechanical strength, strong dirt-trapping capacity, and good acid resistance. It is an important industrial mineral raw material. Because quartz sand is widely used in many fields, it is usually screened before being fed into processing plants to separate quartz sand of different particle sizes for subsequent processing.

[0003] A search revealed that Chinese Patent Publication No. CN210876209U discloses a quartz sand feeding and screening device, including a screening box containing a vibrating box. Two slots are opened on each side of the screening box, and a fixed support is placed in each slot. The middle of each fixed support extends through the inner wall of the slot into the interior of the screening box. The device uses a motor and a rotating wooden block to drive the fixed support in a circular motion, which in turn drives the vibrating box to vibrate, achieving dispersed screening of the quartz sand. This effectively improves screening efficiency and ensures the continuity of screening operations. A scraper removes quartz sand adhering to the conveyor belt, preventing it from falling into the screening box during belt rotation and ensuring cleanliness. Simultaneously, a support device consisting of a support rod, a sliding ball, and a compression spring supports the right side of the vibrating box, ensuring relative balance and improving the stability of the vibrating box during vibration.

[0004] However, in the existing technology, the feeding part of the quartz sand screening device is usually composed of a wide-mouthed inlet, which does not have an auxiliary feeding mechanism inside. This causes the quartz sand to be quickly fed onto the screen plate after being put into the inlet, which makes it easy for the quartz sand to accumulate on the screen plate and affect the screening effect. At the same time, the quartz sand is easy to stick to the inner wall of the inlet, resulting in waste. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quartz sand feeding and screening device, which aims to improve the situation where the feeding part of the quartz sand screening device is usually composed of a wide-mouthed inlet without an auxiliary feeding mechanism inside. This causes the quartz sand to be quickly fed onto the screen plate after being put into the inlet, which makes it easy for the quartz sand to accumulate on the screen plate and affect the screening effect. At the same time, the quartz sand is easy to stick to the inner wall of the inlet, resulting in waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a feeding hopper and a base. The feeding hopper is disposed on the upper end of the base. A mounting frame is fixedly connected to the upper end of the feeding hopper.

A motor is fixedly connected to the upper end of the mounting frame. The output end of the motor is fixedly connected to the upper end of one of the synchronous pulleys. A rotating rod is fixedly connected to the lower end of the other synchronous pulley, passing through one end of the mounting frame. A spiral feeding blade is fixedly connected to the lower end of the rotating rod. An installation rod is fixedly connected to the middle of the rotating rod. A scraper is fixedly connected to one end of the installation rod, and a pusher plate is fixedly connected to the other end of the installation rod.

[0007] As a further description of the above technical solution: After the quartz sand is put into the feeding hopper, the motor drives one of the synchronous pulleys to rotate, which in turn drives the other synchronous pulley to rotate under the action of the transmission belt. At this time, the rotating rod fixed below the other synchronous pulley can rotate accordingly, and the mounting rod fixed on the rotating rod can rotate, thereby driving the scraper and pusher plate fixed at the end to move. At the same time, the spiral feeding blade at the lower end of the rotating rod will also rotate to transport the quartz sand in the feeding hopper. The scraper above can scrape off the quartz sand adhering to the inner wall of the feeding hopper, and the pusher plate can push the quartz sand to move towards the spiral feeding blade.

[0008] Preferably, a conveyor belt mechanism is fixedly connected to the upper end of the base, and a support frame is fixedly connected to both sides of the upper end of the base.

[0009] As a further description of the above technical solution: the conveyor belt mechanism can uniformly and centrally transport the small particles of quartz sand that have been screened out, thus avoiding the accumulation of materials.

[0010] Preferably, guide plates are fixedly connected to the upper ends of both of the No. 1 support frames, and a screening frame is provided at the upper end of the base.

[0011] As a further description of the above technical solution: the guide plate can guide and collect the sieved quartz sand and slide it onto the conveyor belt mechanism.

[0012] Preferably, a second support frame is fixedly connected to all four sides of the upper end of the base, and a buffer mechanism is fixedly connected to the upper end of each of the four second support frames.

[0013] As a further description of the above technical solution: the second support rod can be used to install the buffer mechanism.

[0014] Preferably, each of the four buffer mechanisms is fixedly connected to a connecting frame at its upper end, and one side of each of the four connecting frames is fixedly connected to the perimeter of the screening frame.

[0015] As a further description of the above technical solution: the connecting frame can be used to connect the buffer mechanism and the screening frame.

[0016] Preferably, a screen plate is fixedly connected inside the screening frame, and a discharge chute is fixedly connected to one side of the screening frame.

[0017] As a further description of the above technical solution: the sieve plate can allow small particles of quartz sand to pass through the sieve holes after vibration.

[0018] Preferably, a second discharge chute is fixedly connected to one side of the base, and a third support frame is fixedly connected to all four sides of the lower end of the base.

[0019] As a further description of the above technical solution: the support component at the bottom of the No. 3 support frame device is used to raise the height of the device.

[0020] Preferably, a fixing frame is fixedly connected to both sides of the feeding hopper, and the lower ends of the two fixing frames are respectively fixedly connected to both sides of the base.

[0021] As a further description of the above technical solution: the fixing frame can be used to fix the feeding hopper above the base.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, after the quartz sand is put into the feeding hopper, the motor drives one of the synchronous pulleys to rotate, which in turn drives the other synchronous pulley to rotate under the action of the transmission belt. At this time, the rotating rod fixed below the other synchronous pulley can rotate accordingly, and the mounting rod fixed on the rotating rod can rotate, thereby driving the scraper and pusher plate fixed at the end to move. At the same time, the spiral feeding blade at the lower end of the rotating rod will also rotate to transport the quartz sand in the feeding hopper. The scraper above can scrape off the quartz sand adhering to the inner wall of the feeding hopper, and the pusher plate can push the quartz sand to move towards the spiral feeding blade. In this way, after the quartz sand is put into the feeding hopper, it can be evenly transported by the spiral feeding blade, avoiding the situation where the quartz sand is quickly discharged and accumulated on the screen plate. At the same time, the scraper can scrape off the quartz sand adhering to the inner wall of the feeding hopper in time, avoiding the waste of raw materials.

[0024] 2. In this utility model, after the quartz sand is evenly fed onto the screen plate through the feeding hopper, the vibrating motor on one side of the screening frame will drive the screening frame to vibrate. Subsequently, small particles of quartz sand can fall through the screen plate onto the guide plate and be guided by the guide plate to be concentrated onto the conveyor belt mechanism. The conveyor belt mechanism will then transport them to the second discharge chute for centralized discharge. Larger particles of quartz sand above can gradually move towards the first discharge chute under the vibration of the screen plate and be discharged through the first discharge chute. This method allows the device to quickly and promptly concentrate and transport the screened material when screening quartz sand, avoiding material accumulation and making the device more convenient to use.

[0031] 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.

[0032] Reference Figures 1 to 2 As shown, one embodiment of this utility model includes a feeding hopper 2 and a base 13. The feeding hopper 2 is disposed on the upper end of the base 13. A mounting frame 18 is fixedly connected to the upper end of the feeding hopper 2. Synchronous wheels 6 are rotatably connected to both sides of the upper end of the mounting frame 18. A transmission belt 5 is connected between the two synchronous wheels 6. A motor 4 is fixedly connected to the upper end of the mounting frame 18. The output end of the motor 4 is fixedly connected to the upper end of one of the synchronous wheels 6. A rotating rod 3 is fixedly connected to the lower end of the other synchronous wheel 6, which passes through one end of the mounting frame 18. A spiral feeding blade 17 is fixedly connected to the lower end of the rotating rod 3. A mounting rod 7 is fixedly connected to the middle of the rotating rod 3. A scraper rod 15 is fixedly connected to one end of the mounting rod 7, and a pusher plate 16 is fixedly connected to the other end of the mounting rod 7.

[0033] In this embodiment, after the quartz sand is fed into the feeding hopper 2, the motor 4 drives one of the synchronous pulleys 6 to rotate, which in turn drives the other synchronous pulley 6 to rotate under the action of the transmission belt 5. At this time, the rotating rod 3 fixed below the other synchronous pulley 6 can rotate accordingly, and the mounting rod 7 fixed on the rotating rod 3 can rotate, thereby driving the scraper rod 15 and the pusher plate 16 fixed at the end to move. At the same time, the spiral feeding blade 17 at the lower end of the rotating rod 3 will also rotate accordingly, thereby moving the quartz sand in the feeding hopper 2. Quartz sand is conveyed, and the scraper 15 above can scrape off the quartz sand adhering to the inner wall of the feeding hopper 2. The pusher plate 16 can push the quartz sand to move towards the spiral feeding blade 17. In this way, after the quartz sand is put into the feeding hopper 2, it can be evenly conveyed by the spiral feeding blade 17, avoiding the situation where the quartz sand is quickly discharged and accumulated on the screen plate 9. At the same time, the scraper 15 can scrape off the quartz sand adhering to the inner wall of the feeding hopper 2 in time, avoiding the waste of raw materials.

[0034] Example 2, as Figure 1 , Figure 3 and Figure 4 As shown, a conveyor belt mechanism 14 is fixedly connected to the upper end of the base 13. A first support frame 21 is fixedly connected to both sides of the upper end of the base 13. A guide plate 20 is fixedly connected to the upper end of each of the two first support frames 21. A screening frame 1 is provided at the upper end of the base 13. A second support frame 19 is fixedly connected to all four sides of the upper end of the base 13. A buffer mechanism 11 is fixedly connected to the upper end of each of the four second support frames 19. A connecting frame 10 is fixedly connected to the upper end of each of the four buffer mechanisms 11. One side of each of the four connecting frames 10 is fixedly connected to the four sides of the screening frame 1. A screen plate 9 is fixedly connected inside the screening frame 1. A first discharge chute 23 is fixedly connected to one side of the screening frame 1. A second discharge chute 12 is fixedly connected to one side of the base 13. A third support frame 22 is fixedly connected to all four sides of the lower end of the base 13. A fixing frame 8 is fixedly connected to both sides of the feeding hopper 2. The lower ends of the two fixing frames 8 are fixedly connected to both sides of the base 13.

[0035] In this embodiment, after the quartz sand is evenly fed onto the screen plate 9 through the feeding hopper 2, the vibrating motor on one side of the screening frame 1 will drive the screening frame 1 to vibrate. Then, the small particles of quartz sand can fall onto the guide plate 20 through the screen plate 9, and be guided by the guide plate 20 to be concentrated onto the conveyor belt mechanism 14. The conveyor belt mechanism 14 will then transport them to the second discharge chute 12 for centralized discharge. The larger particles of quartz sand above can gradually move towards the first discharge chute 23 under the vibration of the screen plate 9, and be concentratedly discharged through the first discharge chute 23. This method allows the device to quickly and timely concentrate and transport the screened material when screening quartz sand, avoiding the accumulation of material and making the device more convenient to use.

[0036] Working Principle: After quartz sand is fed into the feeding hopper 2, the motor 4 drives one of the synchronous pulleys 6 to rotate, which in turn drives the other synchronous pulley 6 to rotate under the action of the transmission belt 5. At this time, the rotating rod 3 fixed below the other synchronous pulley 6 can rotate accordingly, and the mounting rod 7 fixed on the rotating rod 3 can rotate, thereby driving the scraper rod 15 and the pusher plate 16 fixed at the end to move. At the same time, the spiral feeding blade 17 at the lower end of the rotating rod 3 will also rotate, thereby conveying the quartz sand in the feeding hopper 2. The scraper rod 15 above can scrape off the quartz sand adhering to the inner wall of the feeding hopper 2, and the pusher plate 16 can push the quartz sand towards the spiral feeding blade 17. In this way, after the quartz sand is fed into the feeding hopper 2, it can be evenly conveyed by the spiral feeding blade 17, avoiding rapid feeding of quartz sand. The material accumulates on the screen plate 9, while the scraper rod 15 can promptly scrape off the quartz sand adhering to the inner wall of the feeding hopper 2, avoiding waste of raw materials. After the quartz sand is evenly fed from the feeding hopper 2 onto the screen plate 9, the vibrating motor on one side of the screening frame 1 will drive the screening frame 1 to vibrate. Then, small particles of quartz sand can fall through the screen plate 9 onto the guide plate 20, and be guided by the guide plate 20 to be concentrated onto the conveyor belt mechanism 14, and then conveyed by the conveyor belt mechanism 14 to the second discharge chute 12 for centralized discharge. The larger particles of quartz sand above can gradually move towards the first discharge chute 23 under the vibration of the screen plate 9, and be concentratedly discharged through the first discharge chute 23. This method allows the device to quickly and promptly concentrate and transport the screened material when screening quartz sand, avoiding material accumulation and making the device more convenient to use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
