[0028] The following further describes the embodiments of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Embodiment 1: As shown in the attached Figure 1 to the attached Figure 2 figures: The present invention provides an automatic drinking water filtering device for caged laying hens, including a filtering box 1. An inlet hopper 2 is fixedly installed on the upper surface of the filtering box 1. A water outlet pipe 3 is fixedly communicated with the side wall of the filtering box 1. A first filter plate 4 is slidably arranged in the filtering box 1. A second filter plate 5 is fixedly installed in the filtering box 1. A filter element plate 6 is slidably arranged on the front end faces of the first filter plate 4 and the second filter plate 5. A maintenance door 7 is rotatably arranged on the front end face of the filtering box 1 through a hinge. The maintenance door 7 can facilitate the quick disassembly and maintenance of the internal filter element plate 6 and the like. At the same time, the maintenance door 7 has sealing performance when closed. By arranging the first filter plate 4 and the second filter plate 5, the water body can be filtered doubly, improving the filtering effect of the device. By arranging the filter element plate 6, the filtering effect of the filter plate can be improved.

[0030] A fixed pipe 8 is fixedly installed on the side wall of the filtering box 1. An adjusting pipe 9 is slidably arranged in the fixed pipe 8. One end of the adjusting pipe 9 is fixedly connected with a push rod 10. A plurality of uniformly distributed scraping plates 11 are fixedly installed on the side wall of the push rod 10. A scraping block 12 is fixedly installed on the lower surface of the scraping plate 11. The scraping block 12 contacts the upper surface of the second filter plate 5. By arranging the scraping plates 11 and the scraping blocks 12, the upper surface of the second filter plate 5 can be scraped and cleaned when needed, reducing the accumulation and adhesion of impurities and the like above the second filter plate 5, thereby causing blockage to the second filter plate 5 and affecting the filtering effect of the device.

[0031] As can be seen from the above, during use, after connecting the water outlet pipe 3 of the filtering box 1 to the drinking water pipe of the laying hens, water is introduced into the filtering box 1 through the inlet hopper 2. The drinking water for the laying hens is filtered doubly through the first filter plate 4 and the second filter plate 5, improving the filtering effect of the filtering box 1. The filtered drinking water enters the drinking water pipe of the laying hens through the water outlet pipe 3 for automatic feeding of water. At the same time, by arranging the scraping plates 11 and the scraping blocks 12, the upper surface of the second filter plate 5 can be scraped and cleaned when needed, reducing the accumulation and adhesion of impurities and the like above the second filter plate 5, thereby causing blockage to the second filter plate 5 and affecting the filtering effect of the device.

[0032] Embodiment 2: As shown in the attached Figure 2 to the attached Figure 7As shown: This embodiment is basically the same as the previous one, except that a fixed pipe 8 is fixedly installed on the side wall of the filtering box 1. An adjusting pipe 9 is slidably arranged in the fixed pipe 8. One end of the adjusting pipe 9 is fixedly connected to a push rod 10. A number of uniformly distributed scraping plates 11 are fixedly installed on the side wall of the push rod 10. A scraping block 12 is fixedly installed on the lower surface of the scraping plate 11. The scraping block 12 contacts the upper surface of the second filter plate 5. By arranging the scraping plates 11 and the scraping blocks 12, the upper surface of the second filter plate 5 can be scraped and cleaned when needed, reducing the accumulation and adhesion of impurities and the like above the second filter plate 5, thereby causing blockage of the second filter plate 5 and affecting the filtering effect of the equipment. The side wall of the filtering box 1 is fixedly connected to a mounting frame 13. A driving motor 14 is fixedly connected to the side wall of the mounting frame 13. The output end of the driving motor 14 is fixedly connected to a rotating rod 15 through a coupling. An active pulley 16 is fixedly sleeved on the outer surface of the rotating rod 15. A driven pulley 17 is rotatably arranged on the side wall of the fixed pipe 8. The active pulley 16 and the driven pulley 17 are connected by a belt drive. Through this setting, when the driving motor 14 drives the rotating rod 15 to rotate, the driven pulley 17 can be driven to rotate.

[0033] Preferably, a connecting rod 18 is fixedly connected to the side wall of the driven pulley 17. An extrusion block 19 is fixedly installed at one end of the connecting rod 18. Arc-shaped grooves 20 and vertical parts 21 are alternately arranged on the side wall of the adjusting pipe 9. The extrusion block 19 contacts the arc-shaped groove 20. A fixing plate 22 is fixedly installed on the outer surface of the push rod 10. A return spring 23 is sleeved on the outer surface of the push rod 10. The two ends of the return spring 23 are respectively connected to the side wall of the fixing plate 22 and the inner side wall of the filtering box 1. When the driven pulley 17 rotates, it drives the connecting rod 18 and the extrusion block 19 to rotate. The extrusion block 19 contacts the arc-shaped surface groove of the adjusting pipe 9. When the adjusting block rotates, it squeezes the arc-shaped groove 20 and squeezes it inward. When it slides to the vertical part 21, the extrusion on the adjusting pipe 9 is released at this time. At this time, the adjusting pipe 9 is driven by the return force of the return spring 23 to drive the fixing plate 22, the push rod 10 and the adjusting pipe 9 to slide back to their original positions, and the adjusting pipe 9 is driven to reset again, so that the adjusting block contacts the arc-shaped groove 20 again for the next extrusion. In this way, the reciprocating sliding of the push rod 10 is realized. At the same time, a number of uniformly distributed scraping plates 11 and scraping blocks 12 are fixedly installed on the side wall of the push rod 10. During the reciprocating sliding of the push rod 10, the scraping block 12 reciprocally scrapes the second filter plate 5, scraping and cleaning the impurities and the like accumulated and adhered to the upper side of the second filter plate 5, reducing the phenomenon that it blocks the second filter plate 5 during use and affecting the use of the second filter plate 5.

[0034] Further, a mounting plate 24 is fixedly connected to the inner side wall of the filter box 1. A limiting rod 25 is fixedly connected to the lower surface of the mounting plate 24. The limiting rod 25 passes through the first filter plate 4 and is slidably arranged therewith. By providing the limiting rod 25, it is convenient to limit the first filter plate 4 during the sliding process. One end of the rotating rod 15 extends into the filter box 1 and a cam 26 is fixedly sleeved on its outer surface. The cam 26 contacts the first filter plate 4. A tension spring 27 is sleeved on the outer surface of the limiting rod 25. By providing the tension spring 27, it is convenient to reset the first filter plate 4. The two ends of the tension spring 27 are respectively connected to the side wall of the mounting plate 24 and the side wall of the first filter plate 4. With this arrangement, when the rotating rod 15 rotates, the cam 26 is driven to rotate. During the rotation of the cam 26, it will contact the upper first filter plate 4 and perform intermittent knocking treatment on it, thereby realizing the intermittent vibration of the first filter plate 4 and reducing the possibility of impurities and the like accumulating on the upper side of the first filter plate 4 and causing it to become blocked.

[0035] Further, an anti - detachment cover 28 is fixedly connected to the lower surface of the limiting rod 25. By providing the anti - detachment cover 28, it is convenient to limit the first filter plate 4 and reduce the possibility of its detachment.

[0036] As can be seen from the above, during use, the driving motor 14 is started. The driving motor 14 drives the rotating rod 15 to rotate. During the rotation process, the cam 26 is driven to rotate. During the rotation of the cam 26, it will contact the upper first filter plate 4 and perform intermittent knocking treatment on it, thereby realizing the intermittent vibration of the first filter plate 4 and reducing the possibility of impurities and the like accumulating on the upper side of the first filter plate 4 and causing it to become blocked.

[0037] At the same time, during the rotation of the rotating rod 15, the driving pulley 16 and the transmission belt are provided to drive the driven pulley 17 to rotate. When the driven pulley 17 rotates, the connecting rod 18 and the extrusion block 19 are driven to rotate. The extrusion block 19 contacts the arc - shaped surface groove of the adjusting block. When the adjusting block rotates, the arc - shaped surface groove 20 is extruded and pushed inward. When it slides to the vertical part 21, the extrusion on the adjusting pipe 9 is released at this time. At this time, the adjusting pipe 9 is driven by the resilience of the return spring 23 to drive the fixing plate 2422, the push rod 10 and the adjusting pipe 9 to perform a reset sliding, and the adjusting pipe 9 is redriven to reset, so that the adjusting block contacts the arc - shaped surface groove 20 again for the next extrusion. In this way, the reciprocating sliding of the push rod 10 is realized. At the same time, a plurality of uniformly distributed scraping plates 11 and scraping blocks 12 are fixedly installed on the side wall of the push rod 10. During the reciprocating sliding of the push rod 10, the scraping block 12 reciprocally scrapes the second filter plate 5, and scrapes and cleans the impurities and the like accumulated and adhered to the upper side of the second filter plate 5, reducing the phenomenon that it blocks the second filter plate 5 during use and affects the use of the second filter plate 5.

[0038] Example Three: As shown in the appendix Figure 6As shown: On the basis of the first embodiment, an installation groove 29 is formed on the lower surface of the filter element plate 6. A clamping block 30 is slidably arranged in the installation groove 29. Clamping holes matched with the clamping block 30 are formed on the lower surfaces of the first filter plate 4 and the second filter plate 5. The clamping block 30 extends out of the clamping hole and is slidably arranged therein. A compression spring 31 is slidably arranged in the installation groove 29. Two ends of the compression spring 31 are respectively connected with the side wall of the clamping block 30 and the side wall of the installation groove 29. During use, the filter element plate 6 is inserted into the first filter plate 4 and the second filter plate 5. When it slides to the clamping hole, at this time, the clamping block 30 is driven by the extrusion force of the compression spring 31 to penetrate through the clamping hole, so as to realize the quick fixed installation of the filter element plate 6. When it is necessary to disassemble and clean the filter element plate 6, after pressing the clamping block 30 to press it into the installation groove 29, the filter element plate 6 can be directly pulled out to quickly disassemble the filter element plate 6. Through this setting, the installation and disassembly efficiency of the filter element plate 6 can be improved, and it is convenient to quickly disassemble and clean it.

[0039] Preferably, a buckle groove 32 is formed on the side wall of the filter element plate 6, and a ball 33 is rotatably arranged on the side wall of the filter element plate 6. Through the arranged buckle groove 32, it is convenient to quickly disassemble the filter element plate 6. Through the arranged ball 33, when inserting and installing, the friction between the filter element plate 6 and the first filter plate 4 and the second filter plate 5 can be reduced, which is convenient for inserting and installing.

[0040] As can be seen from the above, during use, the filter element plate 6 is inserted into the first filter plate 4 and the second filter plate 5. When it slides to the clamping hole, at this time, the clamping block 30 is driven by the extrusion force of the compression spring 31 to penetrate through the clamping hole, so as to realize the quick fixed installation of the filter element plate 6. When it is necessary to disassemble and clean the filter element plate 6, after pressing the clamping block 30 to press it into the installation groove 29, the filter element plate 6 can be directly pulled out to quickly disassemble the filter element plate 6. Through this setting, the installation and disassembly efficiency of the filter element plate 6 can be improved, and it is convenient to quickly disassemble and clean it. When disassembling, through the arranged buckle groove 32, it is convenient to quickly disassemble the filter element plate 6.
