When extracting the gaseous medium, the first hole 1103A can communicate with the bypass interface 201 of the fan assembly 20, and is driven by the negative pressure of the fan assembly 20 to realize the extraction of the gaseous medium in the first chamber 1104A of the drum 111, making the first chamber Negative pressure is formed in 1104A, so that the airflow outside the cylinder 111 can blow brush bristles 112, and enter into the first cavity 1104A from the first through hole 1101, realize the cleaning of bristles 112, and also can pass through the second through hole 1102 and the straw 116 absorbs dust and other pollutants on the inner side of the filter screen 12 to clean the filter screen 12 .

In addition, the dust and other pollutants adsorbed by the gas medium in the first cavity 1104A can bypass the interface 201 and enter the negative pressure area of the fan assembly 20, and flow to the garbage bin 30 under the action of the fan assembly 20, and finally can be deposited in the garbage. box 30, or enter the dust box 100 with the airflow to be filtered and sucked until it falls into the dustbin 30.

Of course, according to the actual situation, the bypass interface 201 can also communicate with the positive pressure area in the fan assembly 20, so as to pass the gas medium into the cavity through the connection hole 1103. Or the bypass interface 201 can be connected with the water pump 60 to pass the liquid medium into or draw out the cavity through the connection hole 1103 .

As shown in Figures 4 to 9, in some embodiments of the present invention, a second through hole 1102 communicating with the cavity is also provided on the peripheral wall of the roller 111, and the roller brush 11 also includes a radially extending A suction pipe 116 , one end of the suction pipe 116 is connected to the drum 111 and communicates with the second through hole 1102 , and the other end of the suction pipe 116 is open. In the drum, the suction pipe 116 can adsorb the pollutants on the filter screen 12, thereby realizing the cleaning of the filter screen 12.

In detail, in combination with the foregoing embodiments, during the rotation of the drum 111, through the connecting hole 1103 on the drum 111, the gaseous medium can be drawn into the cavity, forming a negative pressure in the cavity, and under the action of the negative pressure , can drive the airflow to enter the cavity after passing through the suction pipe 116 and the second through hole 1102. At this time, the other end of the suction pipe 116 can suck the inside of the filter screen 12, so that the garbage or dust attached to the filter screen 12 Contaminants are sucked away, enabling cleaning of the filter screen 12 .

In some embodiments of the present invention, the length of the suction tube 116 along the radial direction of the drum 111 is shorter than the length of the bristles 112 . Specifically, when the drum 111 rotates relative to the filter screen 12, such setting can make the suction pipe 116 and the filter screen 12 spaced apart by a certain distance, so as to avoid the collision and wear of the suction pipe 116 and the filter screen 12, resulting in the dust removal box 100 damage.

As shown in FIGS. 4 to 9 , in combination with the aforementioned embodiments, the bristles 112 are in contact with the inner peripheral surface of the filter screen 12 to clean the inner peripheral surface of the filter screen 12 , and the other end of the suction pipe 116 is in clearance fit with the filter screen 12 . Therefore, with such setting, the inner peripheral surface of the filter screen 12 can be cleaned multiple times to ensure the filtering effect of the filter screen 12 .

When the cylinder 111 rotates in the dust removal box 100, the bristles 112 connected to the outside of the cylinder 111 can clean the inner peripheral surface of the filter screen 12, and then the cleaned dust can fall into the dustbin through the lower opening of the filter screen 12 30, at the same time, one end of the suction pipe 116 in the roller brush 11 can communicate with the second through hole 1102, and the other end can be matched with the filter screen 12 clearance, and when the gas medium is drawn out from the cavity, the other end of the suction pipe 116 can Negative pressure is formed to absorb dust and other garbage on the inner peripheral surface of the filter screen 12, so as to realize multiple cleanings of the filter screen 12, thereby ensuring the filtering effect of the filter screen 12.

In some embodiments of the present invention, the peripheral wall of the drum 111 is provided with a first row of holes and a second row of holes, and each of the first row of holes and the second row of holes includes a plurality of second The through holes 1102, the first row of holes and the second row of holes are arranged at intervals along the circumference of the drum 111, and are staggered in the axial direction of the drum 111. The suction pipe 116 includes a plurality of corresponding to the plurality of second through holes 1102, And one end of the suction pipe 116 is connected to the drum 111 and communicated with the corresponding second through hole 1102 . Wherein, the staggering of the first row of holes and the second row of holes in the axial direction of the drum 111 means that the projection of the first row of holes and the second row of holes along the radial direction of the drum 111 on the axis of the drum 111 is along the axis of the drum 111. Axially staggered. In other words, during the rotation of the drum 111 , the trajectories of the first row of holes and the second row of holes are staggered in the axial direction of the drum 111 . Therefore, the pollutants on the filter screen 12 can be completely adsorbed by the suction tube 116 , improving the cleaning efficiency of the filter screen 12 .

Wherein, two rows of suction pipes 116 are provided on the peripheral wall of the drum 111 , one end of one row of suction pipes 116 may correspond to the first row of holes, and one end of the other row of suction pipes 116 may correspond to the second row of holes. In addition, the first row of holes and the second row of holes can be symmetrically arranged along the center line of the drum 111, and the first row of holes and the second row of holes can also be arranged at intervals along the circumference of the drum 111, etc., which is not within the scope of protection of the present invention. In the following, the symmetrical arrangement of the first row of holes and the second row of holes along the center line of the drum 111 will be described as an example.

Example 1

When the filter screen 12 needs to be cleaned, the gaseous medium can be extracted from the first chamber 1104A through the first hole 1103A, so that a negative pressure can be formed in the first chamber 1104A. The first row of holes connected can be rotated to the top of the drum 111, and the suction pipe 116 corresponding to the first row of holes can absorb the pollutants attached to the inner side of the filter screen 12, and then the second row connected to the peripheral wall of the drum 111 The second row of holes can be rotated to the top of the drum 111, and the suction pipe 116 corresponding to the second row of holes can absorb the pollutants attached to the inside of the filter screen 12; Therefore, after the first row of holes has adsorbed part of the pollutants on the filter screen 12, the second row of holes can adsorb the remaining part of the pollutants on the filter screen 12 to achieve a complete filter. The pollutants on the inner side of the net 12 are adsorbed to realize the cleaning of the dust removal box 100 .

Example 2

When the filter screen 12 needs to be cleaned, the gas medium can be extracted from the second cavity 1104B through the second hole 1103B, so that a negative pressure can be formed in the second cavity 1104B. The connected first row of holes can be rotated to the bottom of the roll, and the suction pipe 116 corresponding to the first row of holes can absorb the pollutants attached to the inner side of the filter screen 12, and then the second row connected with the peripheral wall of the drum 111 The row of holes can be rotated to the bottom of the roller, and the suction pipe 116 corresponding to the second row of holes can absorb the pollutants and performance attached to the inner side of the filter screen 12; The axial direction is staggered, therefore, after the first row of holes has adsorbed part of the pollutants on the filter screen 12, the second row of holes can adsorb the remaining part of the pollutants on the filter screen 12, realizing a complete filter screen The pollutants on the inner side of 12 are adsorbed to realize the cleaning of the dust removal box 100.

Of course, the cleaning of the filter screen 12 can be realized by passing the medium into the first cavity 1104A and/or the second cavity 1104B in the drum 111. For example, if the medium is a liquid medium, the liquid medium can pass through the first cavity 1104A and/or the second cavity 1104B, the first row of holes and/or the second row of holes, and can pass through the suction pipe 116 to flush the filter screen 12 . As another example, if the medium is a gaseous medium, the gaseous medium can pass through the first cavity 1104A and/or the second cavity 1104B, the first row of holes and/or the second row of holes, and can pass through the suction pipe 116, so that the filter screen 12 Flushing is carried out to realize the cleaning of the filter screen 12. Therefore, there are many ways to clean the dust removal box 100 by passing the medium into or drawing out the cavity of the drum 111 , which should not be construed as limiting the protection scope of the present invention.

As shown in Figures 1 and 2, according to the road sweeper 1000 in the embodiment of the present invention, the road sweeper 1000 includes a suction nozzle 200, a dustbin 30 and the above-mentioned dust removal box 100, the inlet of the suction nozzle 200 and the fan assembly 20 Connected to suck the rubbish on the ground, the dustbin 30 communicates with the outlet of the fan assembly, and the inlet of the fan assembly 20 communicates with the suction nozzle 200 . Therefore, the road sweeper 1000 can absorb the garbage on the ground, and the dust removal box 100 disposed in the road sweeper 1000 can be self-cleaning, so as to improve the cleaning efficiency of the road sweeper 1000 .

During the operation of the road sweeper 1000, the garbage on the ground can be sucked through the suction nozzle 200. Under the drive of the fan assembly 20, the garbage can enter the dust removal box 100 along with the air flow, and be disposed in the dust removal box 100. The intercepting function of the baffle plate 41 makes the garbage collide and fall in the garbage bin 30, completing the suction of the ground garbage by the road sweeper 1000. In addition, the airflow entraining the dust can pass through the dustbin 30 and enter the dust removal channel 402, and the gap 1201 of the filter screen 12 is set downwards and faces the entrance of the dust removal channel 402, so the air flow can enter from the gap 1201 of the filter screen 12 Inside the box body 10, the airflow entering the box body 10 is first filtered by the bristles 112 to complete the first filtration, and then the airflow can pass through the filter screen 12 to achieve the second filtration, and the filtered airflow can be filtered by the airflow baffle 4241 The role of reducing the flow rate, slowly discharged from the outlet of the fan assembly 20, to avoid harm to the surrounding environment or people. In addition, the bristles 112 outside the cylinder 111 can be wetted by passing a liquid medium into the second cavity 1104B, so as to improve the filtering effect of the airflow.

During the self-cleaning process of the road sweeper 1000, the gaseous medium can be extracted from the first cavity 1104A, so that the bristles can be brushed through the first through hole 1101, the second through hole 1102 and the suction pipe 116 connected to the second through hole 1102. 112. Dust and other pollutants on the inner surface of the filter screen 12 are adsorbed, and during the rotation of the drum 111 relative to the partition 113, the positions of the first chamber 1104A and the second chamber 1104B can remain unchanged, and the first through hole 1101 The first cavity 1104A is switchably connected with the second through hole 1102 to realize the cleaning of the bristles 112 and the filter screen 12, and then the gas medium can flow to the negative pressure area of the fan assembly 20 through the first hole 1103A to re-enter the sweeping path The airflow of the machine 1000 is internally circulated (that is, the airflow circulates through the fan assembly 20, the air intake duct, the dustbin 30, the dust removal channel 402, and the dust removal assembly 10). In addition, in cooperation with the rotation of the bristles 112, the bristles 112 can sweep away pollutants such as dust on the inner side of the filter screen 12, and the swept pollutants can fall into the dustbin 30 through the gap 1201 of the filter screen 12, The self-cleaning of the dust removal box 100 is completed.

During the self-cleaning process of the road sweeper 1000, a liquid medium can be introduced into the second chamber 1104B, so that the first through hole 1101, the second through hole 1102 and the suction pipe 116 connected to the second through hole 1102 can pass through the second cavity 1104B. Bristles 112, dust and other pollutants on the inner side of the filter screen 12 are cleaned, and during the rotation of the cylinder 111 relative to the partition 113, the positions of the first chamber 1104A and the second chamber 1104B can remain unchanged, and the first through hole 1101 and the second through hole 1102 are switchably connected to the second cavity 1104B to clean the bristles 112 and the filter 12 , and then the liquid medium can drop from the gap 1201 of the filter 12 into the dustbin 30 .

According to the road sweeper 1000 in the embodiment of the present invention, by using the aforementioned dust removal box 100, the airflow passing through the dust removal box 100 can be intercepted to remove dust and other garbage entrained in the airflow.

The present invention can improve the self-cleaning effect of the dust removal box 100, so that the dust removal filter system can be cleaned thoroughly, and the equipment does not need to replace the filter mechanism regularly.

The present invention can optimize the dust removal scheme, so that the dust removal box 100 can be used in both dry and wet conditions, ensuring that the equipment can work in both sunny and rainy days.

The invention can enhance the filtering ability of the equipment in the wet dust removal mode such as operation in rainy days, and prevent secondary pollution to the air under the condition of wet filtering.

The road sweeper of the present invention (i.e. road sweeper 1000) is made up of chassis, cleaning mechanism, suction nozzle 200, fan, dustbin 30, dust removal box 100, electrical system, hydraulic system, waterway system, casing appearance etc.

Wherein: the blower fan and the blower fan motor and the blower fan provide driving force for the suction nozzle 200 and the suction pipe 116, and the rubbish is sucked into the dust removal box 100. And fall in the dustbin 30, now the pressure in the dustbin 30 is greater than the normal atmospheric pressure, the gas in the dustbin 30 and the part of the dust mixed in the gas enter the cylinder 111 that is fixed on the filter mechanism of the cylinder 111 on the dust removal box 100 In the first stage between the bristles 112, after being filtered by the second stage of the multi-layer sintered filter screen 12, the dust is blocked by the bristles 112 and the multi-layer sintered filter screen 12, and the multi-layer sintered filter screen 12 can block visible particles above 10um. The filtered gas is blocked and decelerated by the airflow baffle 42, and then discharged into the air.

In some specific examples of the present invention, the dust removal box 100 has a first layer of filtering and self-cleaning mechanism:

1. Filter and dust removal function:

The lower cavity of the roller brush (i.e. the second cavity 1104B) is respectively connected to the high-pressure water pump 60 through the water pipe joint and the water pipe. The high-pressure water pump 60 sends the water flowing in from the water tank through the water filter into the bristle fixing cylinder (i.e. the drum 111) In the lower cavity of the roller brush (i.e. the second cavity 1104B), the water in the cavity is affected by gravity and adheres to the bristles 112 after passing through the air holes of the bristle fixing cylinder (i.e. the roller 111). To maintain a stronger adsorption force, rely on the bristles 112 to remove dust for the first time.

When the gas passes through the bristles 112 around the filter mechanism of the drum 111, because the gaps between the bristles 112 are small, when the gas and dust pass through the bristles 112, the dust is filtered by the dense bristles 112, while the gas passes through the gaps between the bristles 112 Enter above the cylinder 111, rely on the gap between the bristles 112 to filter the dust, and strengthen the first dust removal.

The upper chamber of the roller brush 11 is respectively connected to the front end of the fan unit through the air pipe joint, the air pipe, and the bypass interface 201 of the fan. There is a negative pressure there, which can form a negative pressure in the upper chamber of the roller brush (that is, the first chamber 1104A). , the negative pressure forms an adsorption force around the bristle 112 through the air holes on the bristle fixing cylinder (that is, the cylinder 111), and the tiny particles that have not been filtered through here are adsorbed on the surface of the bristle 112 fixing cylinder (that is, the cylinder 111) and the bristles 112. Between the root gaps, the negative pressure between the bristle fixing cylinders (that is, the cylinder 111) can absorb dust, and the first filtration and second dust removal of the gas are strengthened again.

2. Powerful self-cleaning function:

Simultaneously, when the filter mechanism of the cylinder 111 rotates, the dividing plate 113 is fixed, and the rolling bearing between the dividing plate 113 and the filtering mechanism of the cylinder 111 can play a role of rolling lubrication, and the upper cavity (i.e. the first cavity 1104A), The relative position of the lower cavity of the roller brush (i.e. the second cavity 1104B) remains unchanged, but the bristles 112 and the bristle fixing cylinder (i.e. the cylinder 111) rotate counterclockwise; when the bristles 112 and the bristle fixing cylinder (i.e. the cylinder 111) When the upper chamber (i.e. the first chamber 1104A) absorbs dust, when the bristles 112 and the bristle fixing cylinder (i.e. the cylinder 111) pass through the lower chamber (i.e. the second chamber 1104B) of the roller brush, the lower chamber (i.e. the second chamber 1104B) ) in the bristle fixing cylinder (that is, the cylinder 111) can wash the dust and garbage attached to the bristle 112 and the gap between the bristles 112 and on the bristle fixing cylinder (that is, the cylinder 111) in time, and the filtration of the cylinder 111 Mechanism is self-cleaning.

After the equipment completes the single-field cleaning operation, turn on the large flow switch of the high-pressure water pump 60, increase the power of the high-pressure water pump 60, and form a The high-pressure water flow is jetted under the air hole box dust removal box 100 on the bristle fixing cylinder (that is, the drum 111), cooperates with the self-rotation of the filter mechanism of the drum 111, and performs high-pressure washing on the filter mechanism of the drum 111, and the residue on the bristles 112 The water flow can also scrub the multi-layer sintered filter screen 12 (ie, the filter screen 12).

The first layer of dust removal and filtering mechanism can strengthen the dust removal function through the water system and the air system, and realize self-cleaning through the water system.

In some specific examples of the present invention, the dust removal box 100 has a second layer of filtering and self-cleaning mechanism:

Multi-layer sintered filter screen (filter screen 12): multi-layer sintered filter screen is a multi-layer sintered metal mesh with strong rigidity, which can filter particles above 10um and can be washed repeatedly.

1. Filtration with multi-layer sintered filter

After the gas is filtered by the bristles 112 and absorbed by the negative pressure of the bristle fixing cylinder (i.e., the cylinder 111), the gas and the remaining unfiltered and adsorbed small amount of dust are driven by the positive pressure in the dustbin 30 and need to pass through the multi-layer sintered filter screen (i.e. The filter screen 12) enters the top of the dust removal box 100, and the multi-layer sintered filter screen (i.e. the filter screen 12) can re-filter the visible particles with a diameter greater than 10um in the remaining dust mixed in the gas, and the filtered dust adheres to the multi-layer sintered The side of the filter screen (ie filter screen 12 ) close to the bristles 112 completes the second filtering and dust removal of the gas.

2. Multi-layer sintered filter screen 12 self-cleaning

The motor drives the filter mechanism of the drum 111 to rotate at a low speed after being decelerated by the motor reducer. The dust attached to the inner side of the multi-layer sintered filter screen (i.e. the filter screen 12) is swept into the dustbin 30 below, and the cleaning of the multi-layer sintered filter screen is completed by sweeping the surface of the multi-layer sintered filter screen (i.e. the filter screen 12). (ie the primary automatic cleaning of the filter screen 12).

At the same time, two rows of negative pressure suction pipes 116 are fixed on the filter mechanism of the drum 111, and the two rows of negative pressure suction pipes 116 are staggered from each other. , there is a negative pressure in the negative pressure suction pipe 116, which can suck the dust stuck and filtered in the multi-layer sintered filter screen 12 into the upper cavity of the roller brush 11, and enter the front end of the fan again along with the air pipe, and then enter the dustbin 30 and the dust removal box 100 again. Inside. When the side row pipes rotate into the lower chamber area (i.e. the second chamber 1104B), the staggered second row pipes enter the area of the upper chamber (i.e. the first chamber 1104A) of the rolling brush, and the multi-layer sintered filter screen (i.e. the filter screen 12) Absorb the dust in the dead corners that have not been cleaned. The multi-layer sintered filter (ie filter 12 ) is deeply cleaned by vacuuming the multi-layer sintered filter (ie filter 12 ) with vacuum.

The second layer of dust removal and filter mechanism borrows the rotation of the first layer of filter mechanism to achieve preliminary cleaning, and performs deep self-cleaning through the air system of the first layer of dust removal and filter mechanism.

In some specific examples of the present invention, the dust removal box 100 of the present invention can be used both wet and dry:

Because the drum filter mechanism and the multi-layer sintered filter screen (ie filter screen 12) all need the participation of water under its dust removal and self-cleaning operation environment. The high-pressure water pump 60 is turned on in sunny days, and dust removal and self-cleaning are carried out through the auxiliary drum 111 filter mechanism in the water tank; during rainy days, the cleaning operation will not generate dust, and the high-pressure water pump 60 is turned off, and large particles of garbage will enter the dustbin 30, and the gas and After the small particle garbage enters the dust removal box 100, the small particle garbage will be filtered by the bristles 112 and the multi-layer sintered filter screen (i.e. the filter screen 12), and the gas will be discharged into the air through the rear of the dust removal box 100; the dust removal function under the dry cleaning operation is realized. And the filter function under the wet cleaning operation mode, after two kinds of modes finish work simultaneously, open high-pressure water pump 60, open water pump 60 high-flow switches, carry out high-pressure washing to drum filter mechanism and multi-layer sintered filter screen (being filter screen 12).

Dust removal function:

The lower cavity of the roller brush (i.e. the second cavity 1104B) is respectively connected to the high-pressure water pump 60 through the water pipe joint and the water pipe. The high-pressure water pump 60 sends the water flowing in from the water tank through the water filter into the bristle fixing cylinder (i.e. the drum 111) In the lower cavity of the rolling brush 11 (i.e. the second cavity 1104B), the water in the cavity is affected by gravity and adheres to the bristles 112 after passing through the air holes of the bristle fixing cylinder (i.e. the cylinder 111), and the bristles 112 can be cleaned after being wetted. The dust maintains a stronger adsorption force, and the first dust removal is carried out by relying on the bristles 112 to be wetted with water.

When the gas passes through the bristles 112 around the drum filter mechanism, because the gaps between the bristles 112 are small, when the gas and dust pass through the bristles 112, the dust is filtered by the dense bristles 112, and the gas enters the drum through the gaps between the bristles 112 Above 111, rely on the gap between the bristles 112 to filter the dust, and strengthen the first dust removal.

Driven by the positive pressure in the dustbin 30, the gas filtered by the bristles 112 and the remaining unfiltered and adsorbed dust need to enter the top of the dust removal box 100 through a multi-layer sintered filter screen (ie, the filter screen 12). The filter screen (i.e. the filter screen 12) can re-filter the remaining dust mixed in the gas, so that the dust is attached to the side of the multi-layer sintered filter screen (i.e. the filter screen 12) close to the bristles 112, and the first dust removal of the gas is strengthened again .

In some specific examples of the present invention, the present invention has multiple waterproof sealing structures:

The waterproof rubber retaining ring is clamped on the fixed end cap and remains relatively still with the fixed end cap. The rubber lip of the waterproof rubber retaining ring is closely attached to the inner wall of the bristle 112 fixing cylinder. When the bristle fixing cylinder (that is, the roller 111) rotates, the waterproof The extrusion and friction between the lips of the rubber retaining ring and the roller 111 can provide a first-level waterproof sealing effect between the bristle 112 fixed cylinder and the fixed end cover (ie, the first end plate 114 ).

Add an end cover rubber sealing ring (i.e. the first sealing ring 1143) between the fixed end cover (i.e. the first end plate 114) and the dust removal box 100 body. After the rubber sealing ring (i.e. the first sealing ring 1143) is compressed, it can Play the second level of waterproof sealing effect.

In some specific examples of the present invention, in the dry operation mode, a secondary dust removal operation is performed on the gas entering the dust removal box 100 to enhance the dust removal effect of the dust removal box 100 . After a single cleaning operation is completed, the high-pressure cleaning of the bristles 112 on the filter screen 12, the roller brush 11 and the high-pressure water circuit on the bristles 112 and the roller 111 improves the self-cleaning effect of the dust removal box 100, so that the dust removal and filtration system can be cleaned thoroughly, and the equipment does not need regular cleaning. Replace the filter mechanism; use the negative pressure air path of the fan of the equipment itself to perform deep blowback self-cleaning on the filter screen 12. Optimize the structure of the dust removal box 100, so that the dust removal box 100 can be used in both dry and wet conditions, ensuring that the equipment can work in sunny and rainy days; The traditional wet cleaning operation has an additional bristle 112 filtration process, which strengthens the equipment's ability to filter exhaust gas during rainy days, and prevents secondary pollution to the air due to incomplete filtration of small particles attached to the gas under wet filtration. .

The dust removal box 100 in the related art only realizes dust removal simply by filtering through a cloth bag or a filter bag. The technical solution of the present application is as follows: add water to the bristles 112 of the roller brush 11 to improve the dust adsorption force; Filtration, sintered filter screen (i.e. filter screen 12) secondary filtration; add negative pressure between the bristles 112 of the roller brush 11, and solve the problem of dust filtration through negative pressure dust collection, thereby enhancing the dust removal effect of the dust removal box 100 .

In the related art, the bag self-cleaning solution of the dust removal box 100 has poor dust removal effect. In the technical solution of the present application, when the bristles 112 of the rolling brush 11 rotate to the area of the lower cavity of the rolling brush (ie, the second cavity 1104B), the lower cavity of the rolling brush 11 (the second cavity 1104B) sprays a high-pressure water flow, and the high-pressure water flow and Under the action of the garbage itself, the garbage between the bristles 112 can be deeply cleaned; it solves the problem of incomplete self-cleaning in the bag-type rapping dust removal solution in the related technology, and avoids the bag-type dust removal solution being blocked by the bag after a certain period of use The inability to completely self-clean leads to a decrease in the cleaning capacity of the equipment; it strengthens the maintenance-free continuous battery life of the equipment under continuous operation.

Through the rotation of the bristles 112 of the roller brush 11, the surface of the sintered filter screen (i.e. the filter screen 12) is initially self-cleaned; at the same time, the two rows of negative pressure suction pipes 116 mixed in the roller brush 11 pass through the upper cavity of the roller brush 11 (i.e. the first In the case of one chamber 1104A), the upper chamber body (i.e. the first chamber 1104A) will apply a negative pressure to the inside of the suction pipe 116, and the negative pressure suction pipe 116 can perform deep self-cleaning on the sintered filter (i.e. the filter screen 12). Through the above two-step self-cleaning scheme, the self-cleaning effect of the equipment is enhanced.

In this solution, regardless of whether it is sunny or rainy, it is necessary to regularly wash the roller with high-pressure water, and it is necessary to keep the roller brush 11 moist; it avoids the problem of keeping the dust removal box dry to prevent the bag from being blocked as in the dry dust removal equipment in the related art; The dry and wet effect of the dust removal box strengthens the versatility of the equipment;
