Description

Technical Field

[0001] This invention relates to the field of conveying technology, specifically to a vibrating conveying device and method for buckwheat hulling production. Background Technology

[0002] On a buckwheat hulling production line, a vibrating conveyor is usually located after the hulling process and before the screening and separation process, or between multiple hulling processes to carry out material transfer. After being processed by the hulling machine, buckwheat is obtained as a mixture containing grains, husks and dust. A vibrating conveyor is usually used to transfer this mixture to the screening section.

[0003] However, due to the light weight and strong dust adhesion of buckwheat hulls, most existing vibrating conveyors are open or semi-open structures. Under high-speed vibration, a large amount of dust and light hull fragments are dispersed into the workshop, which not only deteriorates the working environment but also causes material loss. Although some production lines have installed suction hoods above the conveyors, the dust collection efficiency of the suction hoods is limited by fixed positions and angles. During the vibrating conveying process, the material is in a high-frequency micro-throwing state, and the actual location and location of dust and debris dispersion are dynamically changing. Fixed air vents can only capture some of the dust, and some dust is raised at positions far from the air vents and then falls back into the material, resulting in insufficient dust removal effect. Summary of the Invention

[0004] This invention proposes a vibrating conveying device and method for buckwheat hulling production, which solves the problem of low dust removal efficiency of fixed-position suction hoods in the prior art during the conveying process.

[0005] The technical solution of the present invention is as follows: A vibrating conveyor for buckwheat hulling production includes a machine body and a conveying trough, and further includes: A cover plate is disposed on top of the conveying trough to form a closed cavity; An elastic support body is provided, and the conveying trough is mounted on the machine body via the elastic support body; A vibration mechanism, mounted on the machine body, is used to drive the conveying trough to vibrate on the elastic support, thereby throwing the material in the conveying trough up for conveying. The vibration mechanism includes: A rotating shaft, which is rotatably mounted on the machine body; An eccentric block is eccentrically disposed on the rotating shaft; A drive sleeve, wherein the eccentric block is rotatably connected inside the drive sleeve; A drive rod is fixedly mounted on the outside of the drive sleeve, and two limiting rings are fixedly mounted on the outside of the drive rod; A vibrating frame is fixedly mounted on the conveying trough. The driving rod and the vibrating frame are in sliding engagement. Two limiting rings are located on both sides of the vibrating frame, and a driving spring is provided between the limiting rings and the vibrating frame. A sieve, which is detachably installed inside the conveying trough, is used to separate buckwheat of different particle sizes; A feeding dust collection assembly, disposed at the inlet of the conveying trough, is used to suck up dust raised during feeding from multiple angles. The feeding dust collection assembly includes: A rotary suction tube is rotatably disposed inside the conveying trough and located at the inlet position, and multiple dust suction ports are connected to the rotary suction tube; A mid-stage dust collection component, positioned in the middle of the conveying trough, is used to dynamically collect dust in conjunction with the vibration and agitation of the material. The mid-stage dust collection component includes: A slit-type air intake is provided on the cover plate and communicates with the middle of the conveying trough; The blowing chamber is connected to the bottom of the conveying trough. A protective net is fixedly installed at the top of the blowing chamber. The blowing chamber is located below the slit-type suction port. The blowing chamber blows air upwards in conjunction with the vibration of the conveying trough to assist the slit-type suction port in dust collection. A discharge dust collection component, wherein the discharge dust collection component is disposed at the discharge port of the conveying trough, and is used to collect residual dust during discharge, the discharge dust collection component comprising: A material discharge plate is fixedly installed at the outlet of the conveying trough. The material discharge plate is connected to the tail end of the screen. The material discharge plate has multiple dust collection holes. A dust collection trough is fixedly installed below the material drop plate to collect dust falling from the material drop plate; A dust collection mechanism, disposed on the conveying trough, is used to collect dust drawn in by the infeed dust collection component, the intermediate dust collection component, and the discharge dust collection component. The dust collection mechanism includes: A dust collection box is fixedly installed on the conveying trough; The dust collection pipe, the rotary suction tube, the slit-type suction port, and the dust collection trough are all connected to the dust collection box through the dust collection pipe; A vacuum pump, wherein the suction port of the vacuum pump is connected to the dust collection box, and the exhaust port of the vacuum pump is connected to the blowing chamber; A dustproof net is installed inside the dust collection box, and the air intake of the vacuum pump and the dust collection box are connected at the location inside the dustproof net.

[0006] To enable the rotation of the rotary suction tube, a drive shaft is coaxially fixedly mounted on the rotary suction tube, and the drive shaft and the rotary shaft are connected in a transmission connection.

[0007] To reduce clogging of the rotating suction cylinder, a cleaning roller is rotatably installed inside the conveying trough. The cleaning roller rotates in opposite directions to the rotating suction cylinder. A cleaning brush is installed outside the cleaning roller, and the cleaning brush contacts the rotating suction cylinder.

[0008] To reduce clogging of the slit-type air intake, a baffle is provided below the slit-type air intake. The baffle is mounted on the cover plate via a telescopic sleeve, and a connecting spring is provided between the baffle and the cover plate.

[0009] To reduce clogging of the dustproof net, the dustproof net has a telescopic structure, comprising an outer net and an inner net, which are slidably fitted together. The outer net is fixedly mounted on the inner top wall of the dust collection box, and a support spring is provided between the bottom end of the inner net and the inner bottom wall of the dust collection box.

[0010] To further reduce clogging of the dust filter, a scraper ring is installed inside the dust collection box that can be raised and lowered. A brush is installed on the inner side of the scraper ring, and the brush is in contact with the dust filter.

[0011] A vibratory conveying method for buckwheat hulling production, using the aforementioned vibratory conveying device for buckwheat hulling production, includes the following steps: S1. After being processed by the hulling machine, the buckwheat is fed into the feed inlet of the conveying trough and falls onto the screen. The buckwheat is screened through the screen, and buckwheat of different particle sizes is conveyed in layers. S2. The vibration mechanism drives the conveying trough to vibrate, and with the elastic support of the elastic support body, the conveying trough and screen throw the buckwheat upwards and move it forward, thus conveying the buckwheat through vibration. S3. When conveying buckwheat, the vacuum pump draws air into the dust collection box, thereby drawing air into the rotary suction tube, the slit suction port and the dust collection trough, while simultaneously sending air into the blowing chamber. S4. The rotary suction tube rotates to suck up the dust raised at the feed inlet. The conveying trough and screen shake up the buckwheat and dust. At the same time, the blower blows air upwards, and the slit-type suction port assists in sucking up the dust in the middle of the conveying trough. S5. The conveying trough and screen vibrate and convey the material to the discharge plate. When the material is discharged, the remaining dust mixed with buckwheat falls into the dust collection trough through the dust discharge hole. S6. Dust accumulates and is collected inside the dust collection box. The dust in the dust collection box is cleaned out and processed regularly. The conveying trough drives the dust collection box to vibrate, which in turn drives the dustproof net to vibrate up and down to help the surface dust fall off. At the same time, the scraper ring drives the brush to rise and fall to clean the dustproof net. S7. As the rotary suction tube rotates, the cleaning brush sweeps the dust off its surface. The conveying trough drives the baffle to vibrate up and down to shake off the dust on its surface. The conveying trough also drives the discharge plate to vibrate, preventing dust from clogging various components.

[0012] The working principle and beneficial effects of this invention are as follows: 1. In this invention, a rotating suction cylinder absorbs the dust generated by the impact during material feeding. The rotation of the suction cylinder expands the dust collection range. In the middle section of the conveying trough, taking advantage of the moment when the material is vibrated and thrown up in a loose state, an upward airflow is formed through the air blowing chamber and the slit-type suction port, causing the dust to be sucked into the slit-type suction port. The material is discharged at the discharge plate after being vibrated and conveyed. When the material falls, the suction force generated by the dust collection trough causes the dust on the discharge plate to fall into the interior of the dust collection trough through the dust collection holes. By performing dust collection operations in multiple stages during the conveying process, the dust removal effect on the buckwheat material is guaranteed.

[0013] 2. In this invention, the material is blocked by the suction port and the dust is drawn into the interior of the rotary suction cylinder. The relative rotation of the rotary suction cylinder and the cleaning roller causes the cleaning brush to clean the surface of the rotary suction cylinder, reducing dust blockage of the suction port. The material is blocked by the baffle net and the dust is drawn into the interior of the slit-type suction port. The conveying trough drives the baffle net to vibrate up and down, shaking off the dust on its surface, thereby reducing blockage of the baffle net. The material is blocked by the dust collection hole and the dust falls into the interior of the dust collection trough. The conveying trough drives the discharge plate to vibrate, shaking the dust into the interior of the dust collection trough, reducing blockage of the dust collection hole, thereby ensuring ventilation and dust removal effect during the conveying process.

[0014] 3. In this invention, a vacuum pump draws dust into the dust collection box and sends air into the blowing chamber. A dustproof net blocks the dust entering the dust collection box and allows air to pass through. The conveying trough drives the dust collection box to vibrate, and the inner net vibrates up and down under the action of the support spring. At the same time, the scraper ring drives the brush to rise and fall, cleaning the surface of the dustproof net, reducing clogging of the dustproof net, ensuring ventilation, and thus further ensuring the dust removal effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 12 As shown in the figure, this embodiment proposes a vibrating conveying device for buckwheat hulling production, including a machine body 1 and a conveying trough 2, as well as a cover plate 3, an elastic support body 4, a vibration mechanism, a screen 5, a feeding dust removal component, a middle section dust removal component, a discharging dust removal component, and a dust collection mechanism.

[0020] The cover plate 3 is set on the top of the conveying trough 2 to form a closed cavity. The cover plate 3 covers the top of the conveying trough 2, reducing the dust escape when the conveying trough 2 vibrates and conveys materials, thus facilitating dust collection, ensuring the cleanliness of the materials, and reducing pollution to the workshop processing environment.

[0021] The conveying trough 2 is mounted on the machine body 1 via an elastic support 4. The elastic support 4 uses an elastic metal plate or leaf spring, with one end fixed to the machine body 1 and the other end fixed to the conveying trough 2 to support the conveying trough 2. At the same time, when the conveying trough 2 is driven by the vibration mechanism, it is allowed to vibrate freely. Multiple sets of elastic support 4 are provided, inclined between the machine body 1 and the conveying trough 2 and symmetrically arranged on both sides of the conveying trough 2. Shock absorbers are generally installed under the machine body 1 to isolate most of the vibration from being transmitted to the ground.

[0022] like Figures 1 to 4As shown, a vibration mechanism is installed on the machine body 1 to drive the conveying trough 2 to vibrate on the elastic support 4, thereby throwing up and conveying the material in the conveying trough 2. The vibration mechanism includes a rotating shaft 101, an eccentric block 102, a drive sleeve 103, a drive rod 104, and a vibration frame 105. The rotating shaft 101 is rotatably mounted on the machine body 1. A motor 106 is installed on the machine body 1. The output end of the motor 106 is connected to the rotating shaft 101 through a transmission mechanism such as a pulley, belt, or sprocket chain. The eccentric block 102 is eccentrically mounted on the rotating shaft 101 and rotatably connected inside the drive sleeve 103. The drive rod 104 is fixedly mounted outside the drive sleeve 103, and two limiting rings 107 are fixedly fitted on the outside of the drive rod 104. 105 is fixedly installed on the conveying trough 2. The drive rod 104 and the vibrating frame 105 are in sliding fit. Two limiting rings 107 are located on both sides of the vibrating frame 105. A drive spring 108 is provided between the limiting rings 107 and the vibrating frame 105. The rotating shaft 101 is driven to rotate by the motor 106. Due to the offset of the eccentric block 102, the rotating eccentric block 102 will generate a periodic centrifugal inertial force. The drive sleeve 103 moves back and forth with its centrifugal motion, thereby driving the drive rod 104 and the drive spring 108 to push and pull the vibrating frame 105 to produce regular vibration. The drive rod 104 is tilted towards the discharge port of the conveying trough 2, which can throw the material up and move it forward at the same time. At the same time, the elasticity of the drive spring 108 plays a rebound buffering role, improving the conveying stability.

[0023] The screen 5 is detachably installed inside the conveying trough 2 to separate buckwheat of different particle sizes. The conveying trough 2 has two installation ports. The screen 5 is slidably installed inside the installation ports. Depending on the buckwheat variety and particle size requirements, a screen 5 with an appropriate aperture can be selected. One or two screens 5 can be used to meet different screening needs, separating the material into two or three different buckwheat products. A baffle 6 is slidably installed on the outside of the conveying trough 2. A slider is fixedly connected to the baffle 6. The conveying trough 2 has a groove that matches the slider. The shape of the baffle 6 and the installation port are adapted and it is close to the outer wall of the conveying trough 2. The screen 5 is installed into the inside of the conveying trough 2 through the installation port. The baffle 6 slides down to block the outside of the installation port to prevent the screen 5 from falling out. The installation port without the screen 5 can also be blocked by the baffle 6 to reduce the escape of material dust and other particles.

[0024] like Figure 3 , Figure 5 and Figure 6As shown, the feeding dust removal assembly is installed at the inlet of the conveying trough 2 to suck up dust raised during feeding from multiple angles. The feeding dust removal assembly includes a rotary suction cylinder 201, which is rotatably installed inside the conveying trough 2 and located at the inlet position. Multiple suction ports 202 are connected to the rotary suction cylinder 201. A drive shaft is coaxially fixedly installed on the rotary suction cylinder 201. The drive shaft is connected to the rotary shaft 101 via a transmission mechanism such as a sprocket, chain, or belt. When the rotary shaft 101 drives the eccentric block 102 to rotate, it can drive the drive shaft and... The rotary suction duct 201 rotates synchronously, driving the dust suction port 202 to draw air into the conveying trough 2. The diameter of the dust suction port 202 is larger than the dust particle size but smaller than the buckwheat particle size to prevent large particles from accidentally entering the air duct. A feed pipe is provided at the inlet. The buckwheat material enters the conveying trough 2 through the feed pipe. When the material enters, a large amount of dust will be generated due to the impact force. By rotating the rotary suction duct 201 to draw air, the dust suction range of the dust suction port 202 is expanded, and the dust is drawn into the interior of the rotary suction duct 201 as much as possible and collected in the dust collection box 501.

[0025] To reduce clogging of the rotary suction cylinder 201, a cleaning roller 203 is rotatably installed inside the conveying trough 2. The cleaning roller 203 and the rotary suction cylinder 201 rotate in opposite directions. A cleaning brush 204 is installed on the outside of the cleaning roller 203, and the cleaning brush 204 contacts the rotary suction cylinder 201. Transmission gears 205 are fixedly installed on the outside of both the cleaning roller 203 and the drive shaft. The two transmission gears 205 mesh to achieve synchronous operation in opposite directions, driving the drive shaft and the rotary suction cylinder 201 through the rotating shaft 101. As the cylinder 201 rotates, the sweeping roller 203 and the rotary suction cylinder 201 rotate synchronously in opposite directions under the action of the transmission gear 205. The sweeping roller 203 drives the sweeping brush 204 to rotate and clean the surface of the rotary suction cylinder 201, especially the dust inlet 202, sweeping off the dust inlet 202 to avoid clogging of the dust inlet 202 and maintain the normal air intake of the rotary suction cylinder 201, thereby ensuring the stability of the dust removal effect and efficiency of the rotary suction cylinder 201.

[0026] like Figure 3 , Figure 5 and Figure 7As shown, the intermediate dust removal component is located in the middle of the conveying trough 2, used to dynamically collect dust in conjunction with the vibration and throwing of materials. The intermediate dust removal component includes a slit-type suction port 301 and a blowing chamber 302. The slit-type suction port 301 is located on the cover plate 3 and communicates with the middle of the conveying trough 2. The blowing chamber 302 is communicated with the bottom of the conveying trough 2. A protective net 303 is fixedly installed at the top of the blowing chamber 302. The blowing chamber 302 is located below the slit-type suction port 301, and blows air upwards in conjunction with the conveying trough 2. The vibration-assisted slit-type suction port 301 of the conveying trough 2 is used to collect dust. The conveying trough 2 drives the screen 5 to vibrate, causing the material on the screen 5, the bottom wall of the conveying trough 2 and the protective net 303 to be thrown upward. The dust is also thrown upward. In the middle of the conveying trough 2, the blowing chamber 302 blows air upward in conjunction with the slit-type suction port 301 to generate an upward airflow. The slit-type suction port 301 is long and narrow and is arranged along the width of the conveying trough 2. It has a strong suction force and uses the airflow pressure difference to guide the vibrated dust to flow into the dust collection mechanism.

[0027] To reduce clogging of the slit-type air intake 301, a baffle 304 is installed below the slit-type air intake 301. The baffle 304 is mounted on the cover plate 3 via a telescopic sleeve. A connecting spring 305 is installed between the inner bottom wall of the baffle 304 and the cover plate 3. The baffle 304 protects the slit-type air intake 301, allowing dust to pass through while preventing materials from directly entering the slit-type air intake 301 and causing clogging. At the same time, under the action of the connecting spring 305, the baffle 304 can vibrate up and down under the vibration of the conveying trough 2, thereby shaking off dust and other particles from the surface of the baffle 304, ensuring the normal dust collection effect of the slit-type air intake 301. The telescopic sleeve can accommodate the up and down vibration of the baffle 304.

[0028] The discharge dust collection component is installed at the discharge port of the conveying trough 2 to collect residual dust during discharge. The component includes a discharge plate 401 and a dust collection trough 402. The discharge plate 401 is fixedly installed at the discharge port of the conveying trough 2, and its tail end is connected to the screen 5. The discharge plate 401 has multiple dust collection holes. The dust collection trough 402 is fixedly installed below the discharge plate 401 to collect dust falling from it. The material is uniformly vibrated and conveyed to the discharge plate 401 by the conveying trough 2. Three discharge plates 401 are installed at the discharge port of the conveying trough 2, corresponding to the positions of the two screens 5 and the inner bottom wall of the conveying trough 2, respectively. Furthermore, the three discharge plates 401 are arranged in a stepped manner, with their lengths decreasing sequentially from top to bottom, facilitating graded collection. The particle size of the material decreases sequentially from top to bottom, thus matching the length of the discharge plates 401 with the particle size of the material. This ensures that the amount of material remaining on different discharge plates 401 is approximately equal. As the material falls along the discharge plates 401, dust falls through the dust collection holes into the dust collection trough 402 for collection. The vibration of the discharge plates 401 caused by the conveying trough 2 reduces dust blockage of the dust collection holes, ensuring normal ventilation and thus guaranteeing the dust absorption effect of the dust collection trough 402. Through the synergistic effect of multi-stage dust removal, dust dispersion throughout the entire process is effectively suppressed.

[0029] A dust collection mechanism is installed on the conveying trough 2 to collect dust drawn in by the infeed dust removal component, the intermediate dust removal component, and the discharge dust removal component. The dust collection mechanism includes a dust collection box 501, a dust collection pipe 502, a vacuum pump 503, and a dustproof screen. The dust collection box 501 is fixedly installed on the conveying trough 2. The rotary suction pipe 201, the slit-type suction port 301, and the dust collection trough 402 are all connected to the dust collection box 501 through the dust collection pipe 502. The suction port of the vacuum pump 503 is connected to the dust collection box 501, and the outlet of the vacuum pump 503 is connected to the blowing chamber 302. The dustproof screen is installed inside the dust collection box 501, with the suction port of the vacuum pump 503 connected to the dust collection box 501 inside the dustproof screen. The vacuum pump 503 draws air into the dust collection box 501, causing the dust collection box 501 to... The interior is under negative pressure, which draws dust through the dust collection pipe 502 to the rotating suction tube 201, the slit-type suction port 301, and the dust collection trough 402. The exhaust air from the vacuum pump 503 forms a circulating airflow through the blowing chamber 302 to aid dust removal, improving the dust removal efficiency and effect in the middle section of the conveying trough 2. This design realizes the integrated operation of buckwheat conveying and efficient dust removal. The connection between the vacuum pump 503 and the dust collection box 501 is protected against blockage by a dustproof net, allowing air to pass through normally while blocking dust, so that the dust is retained inside the dust collection box 501 for collection. The dust collection box 501 has a cleaning port, and a cleaning plate is detachably installed at the cleaning port by bolts. The cleaning plate is opened periodically to clean out the dust inside the dust collection box 501 for centralized treatment.

[0030] To reduce clogging of the dust filter, the dust filter has a telescopic structure, comprising an outer mesh 601 and an inner mesh 602, which are slidably fitted together. The outer mesh 601 is fixedly mounted on the inner top wall of the dust collection box 501. A support spring 603 is installed between the bottom end of the inner mesh 602 and the inner bottom wall of the dust collection box 501. A scraper ring 604 is vertically movable inside the dust collection box 501, and a brush 605 is installed on the inner side of the scraper ring 604. The brush 605 contacts the dustproof net. During the vibrating conveying process, the conveying trough 2 drives the dust collection box 501 and the outer net 601 to vibrate. It can also drive the inner net 602 to vibrate up and down under the action of the support spring 603, shaking off dust from the surface of the dustproof net, ensuring normal air passage and maintaining dust collection efficiency. The dust collection box 501 is internally equipped with a reciprocating screw 606, which is connected to the drive shaft via a transmission mechanism such as a bevel gear set. Figure 5 and Figure 8 As shown, in this embodiment, the reciprocating screw 606 and the drive shaft are connected by a bevel gear set and a sprocket chain. The scraper ring 604 is driven by the reciprocating screw 606 to move up and down along the dustproof net, which drives the brush 605 to clean the surface of the dustproof net, further reducing the adhesion of dust on the dustproof net. The support spring 603 can limit the inner net 602 to prevent it from coming out of the inner net 601.

[0031] It should be noted that both the cleaning brush 204 and the bristle brush 605 have a base plate and bristles. The base plate is detachably mounted on the outside of the cleaning roller 203 and inside the scraper ring 604 by means of bolts or clips. The cleaning brush 204 and the bristle brush 605 can be replaced periodically to avoid dust accumulation inside the cleaning brush 204 and the bristle brush 605 during long-term cleaning work, thereby ensuring the cleaning effect on the rotating suction tube 201 and the dust screen.

[0032] Example 2: This example proposes a vibratory conveying method for buckwheat hulling production, using a vibratory conveying device for buckwheat hulling production as described in Example 1, including the following steps: S1. After being processed by the hulling machine, the buckwheat is fed into the inlet of the conveying trough 2 through the feed pipe and falls onto the screen 5. According to the buckwheat screening requirements, screens 5 with appropriate aperture and quantity are selected and installed into the interior of the conveying trough 2 through the installation port. After installation, the baffle 6 slides down to block the installation port and limit the screen 5. The buckwheat is screened through the screen 5, and buckwheat of different particle sizes is conveyed in layers. S2. The vibration mechanism drives the conveying trough 2 to vibrate. The motor 106 drives the rotating shaft 101 to rotate, thereby driving the eccentric block 102 to rotate eccentrically, driving the drive sleeve 103 and drive rod 104 to move back and forth. Under the drive of the drive spring 108, the vibration frame 105 and the conveying trough 2 are driven to vibrate. With the elastic support of the elastic support body 4, the conveying trough 2 and the screen 5 throw the buckwheat upward and move forward, thus vibrating and conveying the buckwheat. S3. When conveying buckwheat, vacuum pump 503 draws air into the dust collection box 501 to create a negative pressure environment inside, thereby drawing air into the rotary suction tube 201, slit suction port 301 and dust collection trough 402 to collect dust into the dust collection box 501, while simultaneously sending air into the blowing chamber 302. S4. The rotating shaft 101 drives the drive shaft and the rotating suction tube 201 to rotate and suck air, which thoroughly sucks up the dust raised at the feed inlet. The conveying trough 2 and the screen 5 shake up the buckwheat and dust. At the same time, the vacuum pump 503 sends air to the blowing chamber 302, and the blowing chamber 302 blows air upwards. The auxiliary slit-type suction port 301 sucks up the dust in the middle of the conveying trough 2. S5, conveying trough 2 and screen 5 vibrate and convey the material to the discharge plate 401. When discharging, the remaining dust mixed with buckwheat falls into the dust collection trough 402 through the dust discharge hole and is sucked into the dust collection box 501. S6. Dust accumulates and is collected inside the dust collection box 501. The dustproof net blocks the dust, causing it to accumulate inside the dust collection box 501. The dust inside the dust collection box 501 is cleaned out periodically for treatment. The conveying trough 2 drives the dust collection box 501 to vibrate, which in turn drives the dustproof net to vibrate up and down to help the surface dust fall off. At the same time, the drive shaft drives the reciprocating screw 606 to rotate, which drives the scraper ring 604 to drive the brush 605 to reciprocate up and down to clean the dustproof net. S7. As the rotating suction tube 201 and the cleaning roller 203 rotate relative to each other, the cleaning brush 204 sweeps the dust off its surface, especially the dust inlet 202. The conveying trough 2 drives the baffle net 304 to vibrate up and down to shake off the dust on its surface.
