Description

Technical Field

[0001] The invention relates to the technical field of nozzles, and in particular to an adjustable nozzle device for forestry machinery and a use method thereof. Background Art

[0002] The sprinkler is the most important part of the sprinkler system. Pressurized water is sprayed into the air through it, and then dispersed into fine water droplets and evenly scattered on the irrigation area controlled by it. The sprinkler can be installed on fixed or mobile pipelines, on the water pipes of the sprinkler group truss, and on the traction frame of the winch sprinkler. It can form a complete sprinkler or sprinkler system with matching machines and pumps. The performance of the sprinkler and whether it is used properly will play a decisive role in the spraying quality, economy and working reliability of the entire sprinkler system or sprinkler.

[0003] The invention patent with application number CN202410169162.1 discloses a water-saving irrigation anti-clogging sprinkler, including an upper shell, a lower shell, a sprinkler assembly, a water inlet pipe, a rotary drive assembly and a clearing assembly. The inner side of the lower shell is provided with a horizontally arranged partition, the water inlet pipe is fixedly connected to the side wall of the lower shell, and a filter is provided in the center of the partition. The clearing assembly includes a cleaning brush, which is rotatably installed at the bottom of the partition; a sleeve is provided between the partition and the top of the lower shell. The invention cleans the filter by setting a cleaning brush, and filters water through the filter, thereby avoiding clogging of the sprinkler.

[0004] During actual use, impurities will be adsorbed on the surface of the filter under the action of water pressure, making it difficult to clean. The cleaning effect of brushing the filter with a cleaning brush is poor and easy to clog. In addition, the impurities are not dealt with in time after being cleaned and are easily adsorbed on the surface of the filter again. During the spraying process, the spraying angle is single and the spraying effect is poor. Summary of the invention

The support gasket ring is made of rubber material, and the deflection frame deflects outward and relies on the inner side of the support gasket.

[0017] A method for using an adjustable nozzle device for forestry machinery comprises the following steps:

[0018] The first step: the adjustable nozzle device is installed on the working machine by means of bolts and mounting flanges, the water supply pipe is connected to the pipe interface for water supply, and the outer support cylinder is rotated to move downward along the outer side of the connecting pipe rack, so that the outer support cylinder releases the seal of the deflection rack;

[0019] Step 2: When spraying, the water source enters the installation cylinder through the pipe interface along the water supply pipe and flows upward. The water flow is blocked by the first blocking piece to flow along a spiral trajectory, so that the impurities in the water are deviated to the outside and initially filtered. The fertilizer particles in the water that are not completely melted are crushed and fully melted by the crushing cutter head. The impurities flow upward along the outer position and finally enter the sealing cover through the sewage outlet for storage. The relatively clean water on the inner side is filtered by the filter cylinder and then flows upward along the filter cylinder. The first blocking piece will also rotate under the push of the water flow to scrape and clean the surface of the filter cylinder. The impurities separated by scraping will eventually enter the sealing cover for storage;

[0020] Step 3: The water inside the filter cartridge flows upward into the installation box, then flows into the deflection frame through the connecting hose, and finally sprays outward through the water spray pipe at the end of the deflection frame. When the water sprays out, it will generate a reverse thrust on the deflection frame. The reverse thrust makes the deflection frame deflect outward and lean against the inner side of the support gasket, so that the deflection frame expands outward to spray water. By rotating the outer support cylinder to adjust the support height of the support gasket, the angle of the deflection frame when it expands outward to spray can be adjusted;

[0021] Step 4: The reverse thrust of the water flow will also drive the installation box to rotate, and the rotation of the installation box will drive the filter cartridge to rotate. The rotation of the filter cartridge will increase the relative rotation speed of the first blocking plate and the filter cartridge, thereby improving the cleaning effect of the filter cartridge surface. The direction of the water spray pipe is adjusted by the cooperation of the fixing bolt and the rotating ball shell, and the multiple water spray pipes are adjusted to different inclination angles, so that the water spray pipes can cooperate with each other to achieve more spray angles and spray ranges when they are revolving, thereby improving the spray coverage effect;

[0022] Step 5: The water flow sprayed from the water spray pipe will drive the spiral diffusion baffle to rotate, and the sprayed water flow will twist and spray outward under the obstruction of the spiral diffusion baffle, and the water flow that hits the surface of the second blocking piece from the inside will diffuse and spray outward under the obstruction of the second blocking piece;

[0023] Step 6: By rotating the regulating nut, the support rod is driven to move outward, and the support rod pulls the second blocking piece to deform, and the contact surface between the second blocking piece and the sprayed water changes from convex to concave, thereby changing the range of the water body covering the outside during spraying, so as to realize the spraying work under different conditions;

[0024] Step 7: After use, rotate the sealing cover upward to directly expose the impurities stored above the sewage receiving plate. At the same time, inject water through the pipe interface, and the water flows out through the sewage outlet for flushing to complete the maintenance work.

[0025] (III) Beneficial effects

[0026] The present invention provides an adjustable nozzle device for forestry machinery and a method for using the same. The device has the following beneficial effects:

[0027] 1. Large particles of impurities will first deviate to the outside under the action of the centrifugal force generated during the spiral flow. When small particles of impurities are filtered on the surface of the filter cartridge along with the water flow, the water flows from the outside of the filter cartridge obliquely to the inside and upwards. The first blocking piece scrapes upward to reduce the difficulty of scraping and cleaning. The impurities move upward along the outside of the filter cartridge and will eventually be collected and stored inside the sealing cover to prevent the impurities from staying inside the installation cartridge and affecting subsequent filtration.

[0028] 2. The support height of the support gasket ring is adjusted by rotating the outer support tube, thereby adjusting the support height of the support gasket ring to the deflection frame, so as to control the inclination angle of the support ring frame after flipping outward. At the same time, by adjusting the spray angle of the water spray pipe, the adjustable range is further increased. By controlling the outer water spray pipe to spray at different angles, and then rotating it, multiple water spray pipes are rotated and sprayed at different angles, thereby improving applicability and spraying effect.

[0029] 3. The water flow sprayed out through the water spray pipe is first diffused and sprayed outward under the obstruction of the spiral diffusion baffle, and sprays in the direction pointed by the water spray pipe. At the same time, the water flow on the inner side impacts the surface of the second blocking piece and then splashes and sprays outward. By adjusting the curvature and concave-convex curvature of the surface of the second blocking piece, the sandblasting coverage angle can be adjusted. Compared with the general spraying equipment that can only spray at a single angle, the coverage effect is improved, which is convenient for spraying, irrigation and application of pesticides from different angles during forestry operations.

[0030] 4. When there are fertilizer particles remaining in the water, the fertilizer particles move outward under the action of centrifugal force to prevent blockage. When the fertilizer particles come into contact with the crushing cutter head, they are crushed. At the same time, the fertilizer particles move upward along the first blocking piece and get stuck in the notch on the surface of the first blocking piece. Then, the fertilizer is crushed by colliding with the crushing cutter head, so that the device can realize the irrigation function for the water body mixed with fertilizer particles, and can also assist in fully mixing the fertilizer with the water body.

[0031] 5. The coordination of revolution and rotation is achieved through the cooperation of the water spray device and the diffusion spray device. The water flow is diffused and sprayed by means of rotary spray diffusion and blocking impact diffusion. Compared with the spraying method of the atomizing nozzle using fine holes, it is less likely to be blocked and can increase the irrigation volume. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] See also Figure 1-Figure 7 The present invention provides a technical solution: an adjustable nozzle device for forestry machinery, comprising a mounting barrel 1, a filtering and cleaning device 2 that uses centrifugal force for self-cleaning and crushing functions, a water spraying device 5 with adjustable spraying angle, and a diffusion spraying device 6 with adjustable spraying coverage, a mounting flange 11 for fixing with the machinery is installed at the bottom of the mounting barrel 1, a pipe interface 12 for connecting to a water source is installed on the front side wall of the mounting barrel 1, a filtering and cleaning device 2 for centrifugally filtering water and crushing fertilizer particles in the water is arranged inside the mounting barrel 1, a connecting pipe rack 3 is installed on the top of the mounting barrel 1, a mounting box 4 is rotatably installed on the top of the connecting pipe rack 3 through a bearing, a filter barrel 41 for filtering is installed at the bottom of the mounting box 4 and located on the inner side of the connecting pipe rack 3, the bottom end of the filter barrel 41 extends into the mounting barrel 1, a water spraying device 5 with adjustable spraying angle is arranged on the outside of the mounting box 4, and a diffusion spraying device 6 for adjusting the spraying range is arranged at the water outlet position of the water spraying device 5.

[0042] As attached Figure 2 and Figure 3As shown, the filtering and cleaning device 2 includes a rotating ring seat 21, a first blocking piece 22, a crushing blade head 23, a sewage outlet 24, a sewage receiving plate 25 and a sealing cover 26. The rotating ring seat 21 is rotatably installed with the top inner wall of the mounting cylinder 1 through a bearing, the first blocking piece 22 is installed with the bottom of the rotating ring seat 21, the inner side wall of the first blocking piece 22 contacts the outer wall of the filter cylinder 41, the outer side wall of the first blocking piece 22 contacts the inner wall of the mounting cylinder 1, the crushing blade head 23 is installed with the inner wall of the mounting cylinder 1, the sewage outlet 24 is opened on the outer wall of the mounting cylinder 1 and is located below the rotating ring seat 21, and the sewage receiving plate 25 is installed with the sealing cover 26. The sealing cover 26 is installed on the outer wall of the installation cylinder 1 and below the sewage outlet 24. The sealing cover 26 is installed on the outer wall of the installation cylinder 1 and above the sewage outlet 24 through a thread. The bottom of the sealing cover 26 is sleeved on the outer side of the sewage receiving plate 25. Through the cooperation of the sewage receiving plate 25 and the sealing cover 26, a cavity for storing filtered impurities is formed outside the sewage outlet 24. When cleaning, the sealing cover 26 is rotated to move upward to release the clamping connection with the sewage receiving plate 25. The water inside the installation cylinder 1 directly enters the sewage receiving plate 25 through the sewage outlet 24 to be flushed and cleaned. The cleaning operation is convenient.

[0043] As attached Figure 2 , Figure 4 and Figure 5As shown, the water spraying device 5 includes a deflection frame 51, a connecting hose 52, a rotating ball shell 53, a water spraying pipe 54, a fixing bolt 55, an outer support tube 56, a top protective ring 58 and an adsorption fixing ring 59. The deflection frame 51 is hinged to the outer wall of the installation box 4 through a hinge. The deflection frame 51 is arc-shaped. When the water inside the deflection frame 51 is sprayed outward, the deflection frame 51 is driven to flip outward along the outer side of the installation box 4 by the reverse thrust of the water flow. The connecting hose 52 is installed on the outer wall of the installation box 4. The end of the connecting hose 52 away from the installation box 4 is connected to the deflection frame 51. The connecting hose 52 is communicated with the water delivery cavity inside the deflection frame 51. The irrigation water inside the installation box 4 is supplied to the internal cavity of the deflection frame 51 through the connecting hose 52. The connecting hose 52 can be telescopically deformed and will not hinder the deflection of the deflection frame 51. The rotating ball shell 53 is clamped at the end of the deflection frame 51. The spherical shell 53 is extended to the surface outside the deflection frame 51 for installation. The spray angle of the water spray pipe 54 is adjusted by rotating the rotating spherical shell 53. The fixing bolt 55 is threadedly installed with the outer wall of the deflection frame 51. The end of the fixing bolt 55 is inserted into the inside of the deflection frame 51 and contacts with the surface of the rotating spherical shell 53. The rotating spherical shell 53 is fixed by the fixing bolt 55, thereby fixing the spray angle of the water spray pipe 54. The outer support tube 56 is installed with the outer wall of the connecting pipe frame 3 by thread. The top protective ring 58 is located on the outer surface of the mounting box 4 and is installed above the deflection frame 51. A magnet sheet is installed on the inner surface of the deflection frame 51. An adsorption fixing ring 59 for adsorbing the magnet sheet is installed on the outer wall of the mounting box 4 and is located on the inner side of the deflection frame 51. The cooperation between the magnet sheet and the adsorption fixing ring 59 keeps the deflection frame 51 in a fit with the mounting box 4 in a non-working state.

[0044] As attached Figure 5 , Figure 6 and Figure 7As shown, the diffusion spray device 6 includes a support ring frame 61, a spiral diffusion baffle 62, an outer bracket 63, a second blocking piece 64, a positioning sleeve 65, an adjusting nut 66 and a support mandrel 67. The support ring frame 61 is installed with the end of the water spray pipe 54 through a bearing, and the spiral diffusion baffle 62 is installed on the inner side of the support ring frame 61. The water column is twisted in a spiral direction by the blocking of the spiral diffusion baffle 62, thereby improving the diffusion effect of the water flow when it collides with the second blocking piece 64 later. The spiral diffusion baffle 62 extends into the interior of the water spray pipe 54, the outer bracket 63 is installed with the end of the water spray pipe 54, the hard extension of the second blocking piece 64 is fixedly installed with the outer bracket 63, the positioning sleeve 65 is installed with the side of the outer bracket 63 away from the water spray pipe 54, the adjusting nut 66 is rotatably installed with the end of the positioning sleeve 65 through a bearing, the end of the support mandrel 67 is installed with the second blocking piece 64, and the support mandrel 67 is installed with the second blocking piece 64. The end away from the second blocking piece 64 passes through the positioning sleeve 65 and is threadedly connected to the regulating nut 66. The positioning sleeve 65 is restricted so that the support push rod 67 can only move axially along the positioning sleeve 65 and cannot rotate on its own. Then, by turning the regulating nut 66, the regulating nut 66 drives the support push rod 67 to move axially in the positioning sleeve 65 through the thread to adjust the support angle of the second blocking piece 64. A protrusion is provided on the surface of one side of the second blocking piece 64 close to the end of the water spray pipe 54. The protrusion is spherical, and an elastic alloy sheet is clamped on the outer side of the spherical protrusion. A armor-like armor sheet is formed on the surface of the second blocking piece 64 by multiple elastic alloy sheets to improve its impact resistance and service life. The water flow is more dispersed when it impacts the surface of the second blocking piece 64 through the blocking of the protrusion and the outer edge of the elastic alloy sheet is tilted upward, thereby improving the spraying effect.

[0045] As attached Figure 2 and Figure 3 As shown, the first blocking piece 22 is spiral, and the water flow is restricted by the first blocking piece 22 to rotate. When the water flow rotates, the internal impurities are filtered by centrifugal force. A notch is provided on the surface of the first blocking piece 22 for the crushing cutter head 23 to pass through. The fertilizer particles on the outside are crushed by shearing between the crushing cutter head 23 and the notch on the surface of the first blocking piece 22. The size of the notch on the surface of the first blocking piece 22 is larger than the size of the crushing cutter head 23. Small particles in the water will directly pass through the notch and will not be blocked in the notch. Under the restriction of the notch, the waste particles stay longer at the height of the crushing cutter head 23, thereby improving the crushing effect of the crushing cutter head 23 on the fertilizer particles.

[0046] As attached Figure 3As shown, the thickness of the inner side of the cross section of the first blocking piece 22 is greater than the thickness of the outer side, so that when the water body flows upward on the outside of the filter cylinder 41, no matter it contacts the upper side surface of the first blocking piece 22 or the lower side surface of the first blocking piece 22, a thrust to move outward will be applied, and the bottom end of the cross section of the rotating ring seat 21 tilts upward from the inside to the outside, and the size of the inner opening of the sewage outlet 24 is smaller than the size of the outer opening. Impurities moving to the bottom of the rotating ring seat 21 will be offset to the outside, and the impurities entering the sewage outlet 24 will convert the vertical force into a lateral moving force through the obstruction of the inclined surface, so that the impurities are automatically moved outward and discharged.

[0047] As attached Figure 6 As shown, the second blocking piece 64 is arc-shaped and made of rubber. The water column is blocked by the second blocking piece 64 to achieve a diffusion effect outward, and the deformation angle of the second blocking piece 64 can be adjusted by adjusting the supporting length of the supporting top rod 67, so that the effect of multi-angle spraying can be achieved through adjustment.

[0048] As attached Figure 5 As shown, the deflection frame 51 is installed at an angle. When the deflection frame 51 is unfolded outward, the spray angle and the spray height of the water spray pipe 54 at its end are different according to the different unfolding angles. Individuals can adjust them according to their needs, thereby improving the adaptability range of the spraying angle.

[0049] As attached Figure 2 As shown, a water filter hole is opened at the bottom of the outer support tube 56, and the residual water inside the outer support tube 56 is discharged through the water filter hole. A support gasket 57 for reducing friction is installed on the top of the outer support tube 56 through a bearing rotation. The support gasket 57 is made of rubber material. The deflection frame 51 deflected outward is supported by the support gasket 57, and then the rotation of the deflection frame 51 will drive the support gasket 57 to rotate synchronously, thereby preventing the deflection frame 51 from directly contacting the outer support tube 56 and causing movement friction to affect the service life of the deflection frame 51.

[0050] A method for using an adjustable nozzle device for forestry machinery comprises the following steps:

[0051] Step 1: Install the adjustable nozzle device on the working machine by means of bolts and the mounting flange 11, connect the water supply pipe to the pipe interface 12 for water supply, rotate the outer support cylinder 56 to move downward along the outer side of the connecting pipe rack 3, so that the outer support cylinder 56 releases the seal of the deflection frame 51;

[0052] Step 2: When spraying, water source enters the installation cylinder 1 through the pipe interface 12 along the water supply pipe and flows upward. The water flow is blocked by the first blocking piece 22 to flow along a spiral trajectory, so that impurities in the water are deviated to the outside and initially filtered. The fertilizer particles in the water that are not completely melted are broken and fully melted by the crushing cutter head 23. The impurities flow upward along the outer position and finally enter the sealing cover 26 through the sewage outlet 24 for storage. The relatively clean water on the inner side is filtered by the filter cylinder 41 and then flows upward along the filter cylinder 41. The first blocking piece 22 will also rotate under the push of the water flow to scrape and clean the surface of the filter cylinder 41. The impurities separated by scraping will eventually enter the sealing cover 26 for storage.

[0053] Step 3: The water inside the filter cartridge 41 flows upward into the installation box 4, and then flows into the deflection frame 51 through the connecting hose 52, and finally sprays outward through the water spray pipe 54 at the end of the deflection frame 51. When the water is sprayed out, it will generate a reverse thrust on the deflection frame 51. The reverse thrust makes the deflection frame 51 deflect outward and lean against the inner side of the support gasket 57, so that the deflection frame 51 is expanded outward to spray water. By rotating the outer support cylinder 56 to adjust the support height of the support gasket 57, the angle of the deflection frame 51 when it is expanded outward for spraying can be adjusted;

[0054] Step 4: The reverse thrust of the water flow will also drive the installation box 4 to rotate, and the rotation of the installation box 4 will drive the filter cartridge 41 to rotate. The rotation of the filter cartridge 41 will increase the relative rotation speed of the first blocking sheet 22 and the filter cartridge 41, thereby improving the cleaning effect of the surface of the filter cartridge 41. The direction of the water spray pipe 54 is adjusted by the cooperation of the fixing bolt 55 and the rotating ball shell 53, and the multiple water spray pipes 54 are adjusted to different inclination angles, so that the water spray pipes 54 can cooperate with each other to achieve more spray angles and spray ranges when they are revolving, thereby improving the spray coverage effect;

[0055] Step 5: The water flow sprayed from the water spray pipe 54 drives the spiral diffusion baffle 62 to rotate. At the same time, the sprayed water flow is twisted and sprayed outward under the obstruction of the spiral diffusion baffle 62. At the same time, the water flow that hits the surface of the second blocking sheet 64 from the inside is diffused and sprayed outward under the obstruction of the second blocking sheet 64.

[0056] Step 6: By rotating the regulating nut 66, the support rod 67 is driven to move outward, and the support rod 67 pulls the second blocking piece 64 to deform, and the contact surface between the second blocking piece 64 and the sprayed water changes from convex to concave, thereby changing the range of the water body to the outside during spraying, so as to achieve spraying work under different conditions;

[0057] Step 7: After use, the sealing cover 26 is rotated and moved upward to directly expose the impurities stored above the sewage receiving plate 25, and water is injected through the pipeline interface 12 at the same time. The water flows out through the sewage outlet 24 to perform flushing work, and the maintenance work can be completed.

[0058] The working principle and use process of the present invention are as follows: bolts are used to pass through the screw holes on the surface of the mounting flange 11 to install the device above the spraying machine, and the water supply pipe is connected to the mounting flange 11, and then the outer support cylinder 56 is rotated to move the outer support cylinder 56 downward along the outer side of the connecting pipe rack 3, so that the outer support cylinder 56 releases the sealing protection of the deflection frame 51 and the outer side of the diffusion spraying device 6. After the support height of the outer support cylinder 56 and the support gasket 57 is adjusted according to the needs, the fixing bolt 55 is rotated to release the fixation of the rotating ball shell 53, and the angle of the water spray pipe 54 can be adjusted. After the adjustment is completed, the fixing bolt 55 is rotated to fix the rotating ball shell 53, and the mounting flange 11 is supplied with water through the water supply pipe, and water flows. The water flows through the mounting flange 11 and enters the interior of the mounting cylinder 1. After the water flows through the bottom of the mounting cylinder 1, the pressure increases and the water flows upward along the outside of the filter cylinder 41. The upward-flowing water flows in a spiral trajectory under the obstruction of the first blocking piece 22, and at the same time pushes the first blocking piece 22 to rotate. The water flows along the spiral trajectory and the large particles of impurities in the water body move outward to prevent them from being adsorbed on the surface of the filter cylinder 41. At the same time, the first blocking piece 22 rotates to scrape and clean the surface of the filter cylinder 41 to prevent the surface of the filter cylinder 41 from being blocked. The first blocking piece 22 rotates to push the cleaned impurities upward. After the impurities move to the bottom of the rotating ring seat 21, they move outward through the sewage outlet 24 to the inside of the sealing cover 26 for storage. The water flows in After entering the interior of the filter cartridge 41, it moves upward to the interior of the installation box 4, and then enters the interior of the deflection frame 51 through the connecting hose 52. The water flows along the internal cavity of the deflection frame 51 to the interior of the rotating ball shell 53 and finally is sprayed out through the water spray pipe 54. The water sprayed through the water spray pipe 54 pushes the deflection frame 51 to deflect outward by the reaction force and leans on the inner side of the support pad ring 57. Then, the reaction force of the deflection frame 51 will also push the installation box 4 to rotate. When the installation box 4 rotates, it drives the deflection frame 51 to perform orbital spraying. The water flowing through the end of the water spray pipe 54 is sprayed outward under the obstruction of the spiral diffusion baffle 62. The water sprayed outward will be spirally deflected under the obstruction of the spiral diffusion baffle 62, and the water flow After impacting the surface of the second blocking piece 64, it splashes outward under the obstruction of the second blocking piece 64. When it is necessary to reduce the splashing range, the regulating nut 66 is rotated to drive the supporting top rod 67 to move outward, and the supporting top rod 67 drives the second blocking piece 64 to shrink inward, thereby reducing the deformation arc of the second blocking piece 64 and the protrusion of the second blocking piece 64, so that the deflection angle of the water flow after impacting the surface of the second blocking piece 64 becomes smaller, thereby reducing the spraying irrigation range. After use, the sealing cover 26 is rotated to move upward to directly expose the impurities stored above the sewage receiving plate 25, and water is injected through the pipe interface 12 at the same time. The water flows out through the sewage outlet 24 for flushing, and the maintenance work can be completed.

9. A method for using an adjustable nozzle device for a forestry machine, comprising the adjustable nozzle device for a forestry machine according to claim 8, characterized in that: The following steps are involved: The first step is to mount the adjustable nozzle device on the working machine by means of bolts and a mounting flange (11), connect the water supply pipe to the pipe interface (12) to supply water, rotate the outer support cylinder (56) and move it downward along the outer side of the connecting pipe rack (3), so that the outer support cylinder (56) releases the seal on the deflection rack (51); Step 2: During spraying, water flows along the water supply pipe through the pipe interface (12) into the interior of the installation cylinder (1) and flows upward. The water flows along a spiral trajectory due to the obstruction of the first blocking plate (22), so that impurities in the water are deflected to the outside and initially filtered. Fertilizer particles that are not completely melted in the water are crushed by the crushing blade (23) and fully melted. Impurities flow upward along the outer side and finally enter the sealing cover (26) through the sewage outlet (24) for storage. Cleaner water on the inner side is filtered by the filter cylinder (41) and flows upward along the filter cylinder (41). The first blocking plate (22) is also rotated under the push of the water flow to scrape and clean the surface of the filter cylinder (41). Impurities separated by scraping are finally stored in the sealing cover (26). Step 3: The water inside the filter cartridge (41) flows upward into the installation box (4), then flows into the deflection frame (51) through the connecting hose (52), and finally sprays outward through the water spray pipe (54) at the end of the deflection frame (51). When the water is sprayed out, a reverse thrust is generated on the deflection frame (51). The reverse thrust causes the deflection frame (51) to deflect outward and lean against the inner side of the support gasket ring (57), so that the deflection frame (51) is expanded outward to spray water. By rotating the outer support cylinder (56) and adjusting the support height of the support gasket ring (57), the angle of the deflection frame (51) when it is expanded outward for spraying can be adjusted; Step 4: The reverse thrust of the water flow will also drive the installation box (4) to rotate, and the rotation of the installation box (4) will drive the filter cartridge (41) to rotate. The rotation of the filter cartridge (41) will increase the relative rotation speed of the first blocking plate (22) and the filter cartridge (41), thereby improving the cleaning effect of the surface of the filter cartridge (41). The direction of the water spray pipe (54) is adjusted by the cooperation of the fixing bolt (55) and the rotating ball shell (53), and the plurality of water spray pipes (54) are adjusted to different inclination angles, so that the water spray pipes (54) can cooperate with each other to achieve more spray angles and spray ranges when they are revolving, thereby improving the spray coverage effect; Step 5: The water flow sprayed from the water spray pipe (54) drives the spiral diffusion baffle (62) to rotate, and the sprayed water flow is twisted and sprayed outwards under the obstruction of the spiral diffusion baffle (62). At the same time, the water flow that hits the surface of the second blocking plate (64) from the inside is diffused and sprayed outwards under the obstruction of the second blocking plate (64); Step 6: By rotating the regulating nut (66), the supporting top rod (67) is driven to move outward, and the supporting top rod (67) pulls the second blocking piece (64) to deform, so that the contact surface between the second blocking piece (64) and the sprayed water changes from convex to concave, thereby changing the range of the water body covering the outside during spraying, so as to achieve spraying work under different conditions; Step 7: After use, the sealing cover (26) is rotated and moved upward to directly expose the impurities stored above the sewage receiving plate (25). At the same time, water is injected through the pipeline interface (12), and the water flows out through the sewage outlet (24) to perform flushing, thereby completing the maintenance work.
