Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, specifically to a microbial fertilizer sprayer with an anti-clogging structure. Background Technology

[0002] Microbial fertilizer sprayers are important equipment in modern agriculture for the uniform application of microbial fertilizers. In existing technologies, microbial fertilizers often contain incompletely crushed organic impurities or clumps, which can easily clog filters or nozzles, affecting spraying efficiency. Filters are mostly fixed designs, requiring disassembly of the entire component for cleaning or replacement, which is cumbersome. Single-layer filters cannot meet the needs of both large particle interception and fine particle filtration, resulting in poor anti-clogging effect or incomplete filtration.

[0003] For example, the authorized patent document with application number CN202421503734.7 discloses a microbial fertilizer sprayer, which belongs to the field of microbial fertilizer spraying technology. It includes a bottom support frame, with pulleys connected to the bottom of the bottom support frame, a positioning component on the top of the bottom support frame, and an adjustment component embedded in the top of the bottom support frame. This utility model, by setting the adjustment component, moves the locking block and the gear two apart. Under the rotational connection between the connecting rod and the limiting frame, the spraying pitch angle of the diversion sleeve can be adjusted. Under the elastic force of the spring two, the locking block and the gear two are tightly engaged, which can position the angle of the diversion sleeve. The adjustment is convenient and can make the spraying effect of the device better.

[0004] The aforementioned patents have filters that are mostly fixed designs, requiring disassembly of the entire component for cleaning or replacement, which is cumbersome. Therefore, we need to provide a microbial fertilizer sprayer with an anti-clogging structure. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a microbial fertilizer sprayer with an anti-clogging structure, comprising:

[0026] Material bin 1, and rectangular tube 2 connected to the top of material bin 1;

[0027] The top of the rectangular tube 2 is provided with a feeding funnel 3, the bottom of the feeding funnel 3 is provided with a double-layer filter mechanism 4 for intercepting impurities in the microbial fertilizer, and the surface of the rectangular tube 2 is provided with an installation mechanism 7 for easy removal of the double-layer filter mechanism 4.

[0028] Specifically, the dual-layer filtration mechanism processes impurities in four stages, extending the continuous working time of the equipment and reducing the frequency of clogging. The filter cartridge 43 can be disassembled separately through a threaded connection. The snap-fit ​​frame 73 and the elastic element 70 enable quick assembly and disassembly of the annular plate 41, improving maintenance efficiency and avoiding the problem that a single-layer filter screen cannot meet the needs of both large particle interception and fine particle filtration, resulting in poor anti-clogging effect or incomplete filtration.

[0029] The double-layer filtration mechanism 4 includes an annular plate 41, which is connected to the feed hopper 3. A filter cylinder 42 is fixedly installed at the bottom of the annular plate 41, and a filter cylinder 43 is provided on the surface of the filter cylinder 42. The internal pores of the filter cylinder 42 are larger than the internal pores of the filter cylinder 43.

[0030] In this embodiment, the feed funnel 3 is connected to the rectangular tube 2 to ensure that the double-layer filter mechanism 4 is installed in place. The large-pore filter cylinder 42 is fixed to the bottom of the annular plate 41, and the small-pore filter cylinder 43 is connected to the connecting ring 61 by the mounting ring 62 and screwed on. Check whether the buckle frame 73 is firmly engaged with the buckle blocks 72 on both sides of the annular plate 41 to ensure that the elastic element 70 provides stable downward pressure. The microbial fertilizer is poured into the feed funnel 3 and passes through the filter cylinder 42 and the filter cylinder 43 in sequence. The filter cylinder 1 is used to intercept large particle impurities, and the filter cylinder 43 further filters fine impurities to ensure the fluidity of the liquid fertilizer. The filtered fertilizer flows into the material box 1. Unfiltered impurities remain in the filter cylinder and need to be cleaned regularly. The water pump 11 is started, and the fertilizer in the material box 1 is transported to the spray plate 10 through the pipe 9. The equipment is moved and the fertilizer is evenly sprayed to the target area.

[0031] During maintenance, push the lever 74 of the latch frame 73 upwards. The latch frame 73 moves upwards and rotates to disengage from the surface of the latching block 72. When the latch frame 73 moves upwards, it drives the spring 703 to stretch. The latch frame 73 can rotate and adjust on the push block surface to release the lock on the latching block 72, thereby removing the annular plate 41. By holding the rubber layer collar 63, rotate it counterclockwise to remove the filter cartridge 43. The filter cartridge 43 can be removed for cleaning, and the filter cartridge 42 can be exposed for easy cleaning.

[0032] It also includes a mounting component 6 for disassembling the filter cartridge 43. The mounting component 6 includes a connecting ring 61 fixedly installed at the bottom of the annular plate 41, a mounting ring 62 fixedly installed at the top of the filter cartridge 43, the inside of the connecting ring 61 being threadedly installed with the surface of the mounting ring 62, and a rubber sleeve 63 for easy gripping is fixedly installed at the bottom of the surface of the filter cartridge 43.

[0033] Furthermore, when removing filter cartridge 2 43, hold the rubber sleeve 63 at the bottom of filter cartridge 2 43 (anti-slip design, easy to apply force) and rotate filter cartridge 2 43 counterclockwise to disengage the mounting ring 62 at the top from the thread of the connecting ring 61. Remove filter cartridge 2 43 from the equipment and clean it.

[0034] When installing filter cartridge 2 43, align the mounting ring 62 of filter cartridge 2 43 with the connecting ring 61 at the bottom of the annular plate 41, and rotate filter cartridge 2 43 clockwise until the mounting ring 62 is fully screwed into the connecting ring 61 to ensure a seal. Check that it is installed correctly to avoid loosening that could affect the filtration effect. The threaded connection allows for manual disassembly without tools, significantly reducing maintenance time. The rubber-coated collar 63 provides a non-slip grip, making it easy to operate even in humid environments. If filter cartridge 2 43 is damaged or severely clogged, a new filter cartridge can be directly replaced without replacing the entire filter mechanism, reducing operating costs.

[0035] The mounting mechanism 7 includes grooves 71 on both sides of the annular plate 41. Each groove 71 has a locking block 72 with a protrusion fixedly installed inside. Each locking block 72 has a locking frame 73 on its surface. The rectangular tube 2 has an elastic element 70 for applying downward force to the locking frame 73. The locking frame 73 has a push plate 74 integrally machined on its surface.

[0036] It should be noted that when the lever 74 on the buckle frame 73 is pushed upward with a finger, the buckle frame 73 disengages from the protrusion of the snap-fit ​​block 72, releasing the lock on the annular plate 41. The annular plate 41 is then lifted upward to separate it from the rectangular tube 2. At this time, the filter cartridge 42 can be removed for cleaning or maintenance. A rectangular rubber sleeve (not shown in the figure) is provided at the top of the rectangular frame to improve the sealing performance. Through the design of the lever 74 and the buckle frame 73, operation can be carried out without tools, greatly improving maintenance efficiency. The elastic element 70 continuously applies a downward pulling force to the buckle frame 73 to ensure that the snap-fit ​​block 72 and the buckle frame 73 are tightly engaged, preventing loosening caused by vibration during operation.

[0037] The elastic element 70 includes a push plate 701 hinged to the bottom of the snap-fit ​​frame 73. The bottom of the push plate 701 is fitted with a fixing seat 702 by two springs 703. The fixing seat 702 is fixedly installed on the surface of the rectangular tube 2.

[0038] It is worth noting that when disassembling the annular plate 41, the lever 74 of the buckle frame 73 is pushed upward, causing the buckle frame 73 to disengage from the protrusion of the snap block 72. When the buckle frame 73 moves upward, the push plate 701 hinged at the bottom is lifted, stretching the two springs 703. The continuous rebound force of the springs 703 keeps the buckle frame 73 pressed tightly against the snap block 72. The double spring 703 design evenly distributes the pressure, ensuring a tight fit even if the annular plate 41 is slightly deformed.

[0039] Both springs 703 have long rods 8 movably sleeved inside them. The tops of both long rods 8 are fixedly installed at the bottom of the push plate 701, and the lower ends of both long rods 8 pass through the bottom of the fixing seat 702 and are fixedly installed with anti-detachment parts.

[0040] Specifically, when the push plate 701 moves up and down driven by the buckle frame 73, the long rod 8 slides inside the spring 703 to ensure that the spring 703 is compressed or extended in a straight line. The anti-detachment part at the lower end of the long rod 8 can prevent the long rod 8 from disengaging from the fixed seat 702 when the spring 703 is overstretched. The long rod 8 restricts the lateral displacement of the spring 703 to avoid torsion failure.

[0041] The surface of the material box 1 is connected to a spray plate 10 through a pipe 9. A water pump 11 is installed inside the pipe 9. One side of the spray plate 10 is fixedly installed on the surface of the material box 1 by several short rods.

[0042] Furthermore, the water pump 11 is turned on, and the microbial fertilizer in the material box 1 is pumped to the spray plate 10 through the pipe 9. The spray plate 10 is designed to ensure that the microbial fertilizer is dispersed and covered, avoiding local over-exposure. The water pump 11 provides a stable flow rate, which is suitable for continuous field operations.

[0043] The bottom of the material bin 1 is equipped with a movable frame 12 with casters;

[0044] The material box 1 can be easily moved to different work areas by pushing the bottom pulley.

[0045] This device connects the feed funnel 3 to the rectangular tube 2 to ensure that the double-layer filtration mechanism 4 is installed in place. The large-pore filter cylinder 1 42 is fixed to the bottom of the annular plate 41, and the small-pore filter cylinder 2 43 is connected to the connecting ring 61 by the mounting ring 62 and screwed on. Check whether the buckle frame 73 is firmly engaged with the buckle blocks 72 on both sides of the annular plate 41 to ensure that the elastic element 70 provides stable downward pressure. Pour the microbial fertilizer into the feed funnel 3. The fertilizer passes through the filter cylinder 1 42 and the filter cylinder 2 43 in sequence. The filter cylinder 1 is used to intercept large particles of impurities, and the filter cylinder 2 43 further filters fine impurities to ensure the fluidity of the liquid fertilizer. The filtered fertilizer flows into the material box 1. Unfiltered impurities remain in the filter cylinder and need to be cleaned regularly. Start the water pump 11. The fertilizer in the material box 1 is transported to the spray plate 10 through the pipe 9. Move the equipment and spray the fertilizer evenly to the target area.

[0046] During maintenance, push the lever 74 of the latch frame 73 upwards. The latch frame 73 moves upwards and rotates to disengage from the surface of the latching block 72. When the latch frame 73 moves upwards, it drives the spring 703 to stretch. The latch frame 73 can rotate and adjust on the push block surface to release the lock on the latching block 72, thereby removing the annular plate 41. By holding the rubber layer collar 63, rotate it counterclockwise to remove the filter cartridge 43. The filter cartridge 43 can be removed for cleaning, and the filter cartridge 42 can be exposed for easy cleaning.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
