Technical Field
[0001] This utility model belongs to the field of chain conveyors, specifically, it relates to a chain conveyor dust prevention device. Background Technology
[0002] Chain conveyors are conveyors that use chains for traction and load-bearing, or use slats, metal mesh belts, and rollers mounted on the chains to carry materials. They can be classified into chain type, chain plate type, chain mesh type, and slat type, etc. They are often combined with other conveyors and lifting devices to form production lines with various functions.
[0003] Chinese Patent No. CN222728884U discloses a dust prevention device for a chain conveyor, including a fixed frame. Inside the fixed frame, two sprocket sets are rotatably connected, one on the left and one on the right. The two sprockets are fixedly connected by a rotating rod and connected by a chain. Multiple chain plates are fixedly installed on the upper end of the chain. A motor is fixedly connected to the front end of the fixed frame, and the output shaft of the motor is fixedly connected to the sprocket set on the left end. A blowing assembly and a dust extraction assembly are respectively installed at the upper and lower ends of the fixed frame. A dust collection hood is fixedly connected to the dust extraction end of the dust collector, which is located inside the fixed frame and at the bottom end of the chain plate.
[0004] Existing chain conveyor dust prevention devices use air blowing to clean dust and other impurities from the surface of conveyed goods. After prolonged use, dust accumulates in the dust collection mechanism, causing blockages and reducing the dust collection efficiency. This necessitates frequent disassembly and cleaning of the dust collection mechanism. However, the dust collection mechanism needs to be stopped during cleaning, and if the dust removal mechanism continues to operate, dust will scatter everywhere, polluting the production environment and potentially affecting the normal operation of surrounding equipment. Therefore, this utility model is proposed to address these issues. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a chain conveyor dust prevention device, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A chain conveyor dust prevention device includes: Main frame; The dust collection box is fixed to one side of the main frame. A push plate is slidably fitted inside the dust collection box. Dust collection boxes are installed on both sides of the dust collection box. Scrapers are slidably fitted inside the two dust collection boxes. A pull rod is fixedly installed on one side of each of the two scrapers. A sealing plate is fixedly installed at one end of each of the two pull rods. The sealing plate cooperates with the dust collection box. The drive mechanism is installed on one side of the dust collection box and cooperates with the push plate.
[0007] Optionally, a conveyor motor is fixedly installed on one side of the main frame, and multiple conveyor rollers are rotatably fitted on the inner side of the main frame. One of the conveyor rollers is connected to the conveyor motor via a belt and pulley. Conveyor sprockets are fixedly installed at both ends of the multiple conveyor rollers.

[0008] Optionally, two spray nozzles are fixedly installed on one side of the vacuum chamber, with one end of each nozzle located inside the vacuum chamber.
[0009] Optionally, a blower is installed at one end of the dust collection box, and a filter screen is fixedly installed inside the dust collection box, with the push plate slidingly engaging with the filter screen.
[0010] Optionally, a blower mechanism is provided on the outside of the main frame. The blower mechanism includes a lifting frame, a dust removal nozzle is installed on the lower side of the lifting frame, and a connecting pipe is installed on the upper side of the lifting frame. The dust removal nozzle and the connecting pipe are matched. One end of the connecting pipe is connected to a corrugated pipe, which is matched with a blower.
[0011] Optionally, the blower mechanism also includes lifting boxes fixed on both sides of the main frame.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. Through the cooperation of the dust collection box and the push plate, the drive mechanism moves the push plate inside the dust collection box during use. This can not only sweep the dust inside the dust collection box and push it into the dust collection box, but also clean the surface of the filter screen at the same time. When cleaning the dust collected in the dust collection box, simply pull the sealing plate, and the pull rod will drive the scraper to slide inside the dust collection box, pushing out the dust collected in the dust collection box at the same time. Moreover, there is no need to stop the vacuuming operation when cleaning. 2. Spraying water into the dust collection box through the spray nozzle helps dust settle quickly, suppresses secondary dust re-entrainment, and facilitates the pusher plate's collection of dust. During use, the conveyor roller drives the active rotating rod to rotate. When the active rotating rod rotates, the transmission rod hinged at its end swings eccentrically. Through the linkage transmission principle, it pulls the sliding rod to slide back and forth on the dust collection box. The reciprocating motion of the sliding rod synchronously drives the pusher plate to move back and forth in the dust collection box for cleaning.

Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] Please see Figure 1-3 As shown, this embodiment provides a chain conveyor dust prevention device, including: Main frame 1; The dust collection box 2 is fixed to one side of the main frame 1. A push plate 25 is slidably fitted inside the dust collection box 2. Dust collection boxes 21 are installed on both sides of the dust collection box 2. Scrapers 24 are slidably fitted inside the two dust collection boxes 21. A pull rod 23 is fixedly installed on one side of each of the two scrapers 24. A sealing plate 22 is fixedly installed at one end of each of the two pull rods 23. The sealing plate 22 cooperates with the dust collection box 21. The drive mechanism 3 is installed on one side of the dust collection box 2 and cooperates with the push plate 25.
[0021] Working principle: When the device is running, the drive mechanism 3 drives the push plate 25 inside the dust collection box 2 to slide back and forth. When external dust is sucked into the dust collection box 2, the push plate 25 pushes the dispersed dust into the dust collection boxes 21 on both sides of the dust collection box 2 through the pushing action of the back and forth sliding, so that the dust is stored in the dust collection boxes 21; to prevent dust from accumulating inside the dust collection box 2 and to keep the dust collection channel unobstructed. When the dust collection box 21 needs to be cleaned, there is no need to stop the machine. The operator only needs to quickly pull the sealing plate 22 on the outside of the dust collection box 21. The sealing plate 22 simultaneously drives the connected pull rod 23 and scraper 24 to slide inside the dust collection box 21. During the sliding process, the scraper 24 can scrape off the accumulated dust in the dust collection box 21 and push it out of the box from the position of the sealing plate 22 for quick dust removal. The scraper 24 moves to the position of the sealing plate 22 to block the connection port with the dust collection box 2, reducing the impact on the dust collection function of the dust collection box 2 during the dust removal process, so that the dust collection box 2 can continue to operate. After the dust removal is completed, push the scraper 24 back to its original position to lock the sealing plate 22 and the dust collection box 21 into a seal, so that the dust collection box 21 returns to the dust storage state. The entire dust removal process does not require disassembling the equipment or stopping the machine. It is convenient to operate and does not interrupt the dust collection operation.
[0022] In this embodiment, a conveyor motor 11 is fixedly installed on one side of the main frame 1, and multiple conveyor rollers 12 are rotatably fitted on the inner side of the main frame 1. One of the conveyor rollers 12 is connected to the conveyor motor 11 via a belt and a pulley. Conveyor sprockets 13 are fixedly installed at both ends of the multiple conveyor rollers 12. Two conveyor chains 14 are respectively engaged on the outer side of the opposite conveyor sprockets 13. Multiple conveyor chain plates 15 are fixedly installed on one side of the two conveyor chains 14.
[0023] When conveying, the conveyor motor 11 is started, and the power is transmitted to the conveyor roller 12 through the belt and pulley transmission, driving it to rotate; the conveyor roller 12 drives the conveyor sprocket 13 to drive the conveyor chain 14 to move in a cycle; the two conveyor chains 14 drive the conveyor chain plate 15 to move, and the goods placed on the conveyor chain plate 15 move synchronously with it, so as to carry out directional and stable conveying.
[0024] In this embodiment, a blower 26 is installed at one end of the dust collection box 2, and a filter screen 27 is fixedly installed on the inner side of the dust collection box 2. The push plate 25 is slidably engaged with the filter screen 27. In this embodiment, a blower mechanism 4 is provided on the outer side of the main frame 1. The blower mechanism 4 includes a lifting frame 43. A dust cleaning nozzle 44 is installed on the lower side of the lifting frame 43, and a connecting pipe 45 is installed on the upper side of the lifting frame 43. The dust cleaning nozzle 44 and the connecting pipe 45 are engaged. One end of the connecting pipe 45 is connected to a corrugated pipe 46, and the corrugated pipe 46 is engaged with the blower 26. In this embodiment, the blower mechanism 4 also includes lifting boxes 41 fixed on both sides of the main frame 1. Lifting electric rods 42 are fixedly installed on the inner side of both lifting boxes 41, and the output ends of the two lifting electric rods 42 are fixedly connected to the two ends of the lifting frame 43 respectively.
[0025] The blower 26 generates negative pressure suction, which drives the airflow to carry dust from the surface of the goods into the dust collection box 2. After being filtered by the filter screen 27 fixed inside the dust collection box 2, the dust is retained in the box. The clean airflow is then transported to the dust removal nozzle 44 through the corrugated pipe 46 and the connecting pipe 45. The dust removal nozzle 44 blows the airflow toward the goods being transported, blowing away the dust attached to the surface of the goods. The blown-away dust is then sucked into the dust collection box 2 by the negative pressure, forming a closed loop of dust blowing and dust collection. Furthermore, for goods of different heights, the lifting frame 43 can be raised and lowered by the lifting electric rod 42 in the lifting boxes 41 on both sides of the main frame 1, which will drive the dust removal nozzle 44 on the lower side of the lifting frame 43 to adjust to the appropriate height, which not only facilitates the smooth passage of goods, but also makes it easy for the dust removal nozzle 44 to be in a suitable dust blowing position; the push plate 25 in the dust collection box 2 slides and cooperates with the filter screen 27, which can push the dust retained by the filter to the dust collection box 21 to complete the centralized treatment of dust.
[0026] In this embodiment, two spray nozzles 28 are fixedly installed on one side of the dust collection box 2, with one end of each spray nozzle 28 located inside the dust collection box 2.
[0027] The spray head 28 is connected to an external water pump. Activating the pump supplies water to the spray head 28, causing it to spray a fine water mist into the dust collection box 2. The water mist comes into contact with and combines with the dust inside the dust collection box 2. The water's adsorption properties cause the dust particles to become heavier and settle, inhibiting dust from flying and spreading. This, combined with the filter screen 27, filters both water and dust particles. The settled dust is then pushed together by the push plate 25 driven by the drive mechanism 3 and collected in the dust collection boxes 21 on both sides, reducing the likelihood of dust entering the dust collection box 2 and continuing to fly and spread.
[0028] The drive mechanism 3 in this embodiment includes two active rotating rods 31 rotatably engaged on both sides of the main frame 1. One end of each active rotating rod 31 is rotatably engaged with a transmission rod 32, and one end of each transmission rod 32 is rotatably engaged with a sliding rod 33. The two sliding rods 33 are fixedly connected to both ends of the push plate 25, and both sliding rods 33 are slidably engaged with the dust collection box 2. One end of the active rotating rod 31 in this embodiment is fixed with a rotating shaft, and the rotating shaft is connected to the conveying roller 12 through a belt and a pulley.
[0029] During the conveying operation, the conveying roller 12 rotates under the drive of the conveying motor 11 to convey goods. At the same time, the active rotating rod 31 is driven to rotate on both sides of the main frame 1 through the rotating shaft and belt and pulley transmission assembly fixed at the end of the active rotating rod 31. When the active rotating rod 31 rotates, the transmission rod 32 hinged at its end swings eccentrically, and pulls the sliding rod 33 to slide back and forth on the dust collection box 2 through the linkage transmission principle. Since the sliding rod 33 is fixedly connected to both ends of the push plate 25, the reciprocating motion of the sliding rod 33 synchronously drives the push plate 25 to move back and forth in the dust collection box 2: on the one hand, the push plate 25 pushes the dust in the box to the dust collection boxes 21 on both sides; on the other hand, the push plate 25 slides with the filter screen 27, and can scrape off the dust attached to the surface of the filter screen 27 during the movement, thereby cleaning the filter screen 27 and keeping the ventilation and dust collection smooth.
[0030] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
