Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment technology, specifically a spraying filtrate device. Background Technology
[0002] In agriculture, forestry, and landscaping, spraying is a crucial step in controlling pests and diseases. As a core component of the spraying system, the spray filtration device is primarily used to filter the pesticide solution to remove impurities (such as sediment, pesticide particles, and undissolved chemicals), preventing nozzle clogging and ensuring effective spraying and normal equipment operation.
[0003] When using a pesticide spraying filtrate device, impurities gradually accumulate on the surface of the filter screen. If not cleaned in time, the filter screen pores will become clogged, reducing or even completely interrupting the flow of pesticide. However, cleaning the internal filter screen of existing pesticide spraying filtrate devices is time-consuming and laborious, requiring operators to frequently remove the filter screen for cleaning, which affects the efficiency of pesticide spraying operations.

[0008] Preferably, a sludge collection box is fixedly connected to both sides of the bottom of the device body, and the interior of the sludge collection box is connected to the interior of the device body. A drain pipe is fixedly connected to the bottom of both sides of the sludge collection box, and the interior of the drain pipe is connected to the interior of the sludge collection box.
[0009] Preferably, two rotating shafts are rotatably connected to the left and right sides inside the device body. Worm gears are fixedly connected to the surfaces of the two rotating shafts near the top of the device body. A worm is fixedly connected to the surface of the first reciprocating screw, and the surface of the worm meshes with the surface of the worm wheel.
[0010] Preferably, each of the rotating shafts is fixedly connected to a drive wheel, and the surfaces of two drive wheels located on the same side are connected to a drive belt. Mounting blocks arranged at equal intervals are fixedly connected to both sides of the surface of the drive belt.

This guides the scraped impurities to the collection tank below. When the guide plate moves upward, it is squeezed and contracted by the inside of the device body, thus preventing the formation of a water flow and preventing the impurities from being carried back to the top. This completes the collection of impurities and facilitates centralized sewage discharge. Attached Figure Description

[0018] Please see Figure 1-5This utility model provides a technical solution: a spraying filtrate device, including a device body 1, a mounting box 2 fixedly connected to one side of the device body 1, a first reciprocating screw 9 extending into the mounting box 2 rotatably connected inside the device body 1, a first reciprocating screw seat 11 sleeved on the surface of the first reciprocating screw 9, a scraper 13 provided at the bottom of the first reciprocating screw seat 11, the scraper 13 being fixedly installed on the first reciprocating screw seat 11 by bolts, and a second reciprocating screw 10 extending into the mounting box 2 rotatably connected inside the device body 1. A second reciprocating screw seat 25 is fitted on the surface of the lead screw 10. A brush 12 is provided on the top of the second reciprocating screw seat 25. The brush 12 is fixedly installed on the second reciprocating screw seat 25 by bolts. A filter frame 6 is fixedly connected inside the device body 1. The surface of the second reciprocating screw 10 is rotatably connected to the inside of the filter frame 6. The top of the brush 12 and the bottom of the scraper 13 are in contact with the inside and surface of the filter frame 6, respectively. The brush 12 is used to sweep out large crystal particles in the pores of the filter frame 6, while the scraper 13 is used to scrape off the impurities accumulated on the surface of the filter frame 6.
[0019] Furthermore, two slide rods 27 are fixedly connected inside the device body 1. The two slide rods 27 are located on one side of the first reciprocating lead screw 9 and the second reciprocating lead screw 10, respectively. The surface of the slide rod 27 closer to the first reciprocating lead screw 9 is slidably connected to the inside of the first reciprocating lead screw seat 11, and the surface of the slide rod 27 closer to the second reciprocating lead screw 10 is slidably connected to the inside of the second reciprocating lead screw seat 25. The slide rod 27 closer to the second reciprocating lead screw 10 passes through the surface of the filter frame 6 and is fixedly connected to the inside of the filter frame 6.
[0020] Furthermore, a motor 14 is fixedly connected inside the mounting box 2. The motor 14 is an existing structure and will not be described in detail here. A drive gear 15 is fixedly connected to the surface of the second reciprocating screw 10 extending into the mounting box 2, and a transmission gear 16 is fixedly connected to the surface of the first reciprocating screw 9 extending into the mounting box 2. The surfaces of the drive gear 15 and the transmission gear 16 mesh with each other. The output end of the motor 14 is fixedly connected to one end of the second reciprocating screw 10 extending into the mounting box 2 via a coupling. Starting the motor 14 drives the second reciprocating screw 10 to rotate. The rotation of the second reciprocating screw 10 drives the drive gear 15 to rotate, which in turn drives the transmission gear 16 to rotate. The transmission gear 16 then drives the first reciprocating screw 9 to rotate. Under the constraint of the slide bar 27, the rotation of the first reciprocating screw seat 11 and the second reciprocating screw seat 25 will not cause them to rotate. Instead, it will cause them to reciprocate along the axial direction of the slide bar 27, thereby causing the scraper 13 and the brush 12 to reciprocate against the surface and interior of the filter frame 6.
[0021] Furthermore, a sludge collection box 4 is fixedly connected to both sides of the bottom of the device body 1. The inside of the sludge collection box 4 is connected to the inside of the device body 1. A drain pipe 5 is fixedly connected to the bottom of both sides of the sludge collection box 4. The inside of the drain pipe 5 is connected to the inside of the sludge collection box 4 to facilitate sewage discharge.
[0022] Furthermore, two rotating shafts 18 are rotatably connected to both the left and right sides inside the device body 1. Worm gears 19 are fixedly connected to the surfaces of the two rotating shafts 18 near the top of the device body 1. A worm 17 is fixedly connected to the surface of the first reciprocating screw 9, and the surface of the worm 17 meshes with the surface of the worm gear 19. A transmission wheel 26 is fixedly connected to the surface of each rotating shaft 18. A transmission belt 20 is connected to the surfaces of two transmission wheels 26 on the same side. The transmission belt 20 is made of Teflon material, which has extremely strong chemical stability and prevents corrosion by the liquid. Equally spaced mounting blocks 21 are fixedly connected to both sides of the transmission belt 20. A rotating column 22 is rotatably connected between two opposing mounting blocks 21. A guide plate 23 is fixedly connected to the surface of the rotating column 22. The surface of the rotating column 22 has through holes to reduce the resistance of the liquid to the guide plate 23. The size of the through holes is smaller than the size of the impurities. A torsion spring 24 is movably sleeved on the surface of the rotating column 22. The two ends of the torsion spring 24 are fixedly connected to the mounting block 21 and the guide plate 23, respectively. The torsion of the torsion spring 24 is greater than the resistance of the liquid to the guide plate 23. When the transmission belt 20 rotates and drives the guide plate 23 to move, the downward-moving guide plate 23 is expanded by the elastic force of the torsion spring 24, thereby pushing the surrounding liquid downward to form a water flow. At the same time, it pushes the scraped impurities downward, thereby guiding the scraped impurities to the inside of the collection tank 4 below. The upward-moving guide plate 23 is squeezed and contracted by the inside of the device body 1, thereby not forming a water flow and preventing the impurities from being carried back to the filter frame 6 above.
[0023] Furthermore, an inlet pipe 3 is fixedly connected to the top of the device body 1, and the interior of the inlet pipe 3 is connected to the interior of the device body 1. An outlet pipe 8 is fixedly connected to the bottom of the device body 1. A liquid pump 7 is fixedly connected to the interior of the filter frame 6, and the output end of the liquid pump 7 is connected to the interior of the outlet pipe 8.
[0024] Working Principle: When cleaning the internal filter screen of this type of spray filtrate device is required, firstly, clean water is poured into the device body 1 through the inlet pipe 3. Then, the motor 14 drives the second reciprocating screw 10 to rotate. The rotation of the second reciprocating screw 10 drives the drive gear 15 to rotate, which in turn drives the transmission gear 16 to rotate. The transmission gear 16 then drives the first reciprocating screw 9 to rotate. Under the restriction of the slide bar 27, the rotation of the first reciprocating screw 9 and the second reciprocating screw 10 does not drive the first reciprocating screw seat 11 and the second reciprocating screw seat 25 to rotate. Instead, it causes the first reciprocating screw seat 11 and the second reciprocating screw seat 25 to reciprocate along the axial direction of the slide bar 27. This causes the scraper 13 and the brush 12 to reciprocate against the surface and interior of the filter frame 6, thereby removing the impurities accumulated on the surface of the filter frame 6. The cleaning process involves pushing impurities to both sides of the filter frame 6. Simultaneously, the first reciprocating screw 9 rotates, driving the worm gear 17 to rotate. The worm gear 17 then drives the worm wheel 19 to rotate, which in turn drives the rotating shaft 18 to rotate. The rotating shaft 18 then drives the transmission belt 20 to rotate, which in turn moves the guide plate 23. When the guide plate 23 moves downward, it expands under the influence of the torsion spring 24, pushing the surrounding liquid downward to form a water flow. This guides the scraped impurities to the lower collection tank 4. Meanwhile, the upward-moving guide plate 23 is compressed and contracted by the interior of the device body 1, thus preventing the formation of a water flow and avoiding the re-carrying of impurities upward. After cleaning, the wastewater can be discharged using the drain pipe 5. The cleaning can be completed without removing the filter frame 6, making cleaning convenient and quick without affecting the efficiency of the spraying operation.
