DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] An embodiment of a filtering device for animal husbandry of the present invention is as follows Figures 1 to 9As shown, it includes a sealing mechanism 1 for sealing and collecting dust, an outer filtering mechanism 2 for removing dust from feed, an inner filtering mechanism 3 and a transmission mechanism 4 for providing kinetic energy. The inner filtering mechanism 3 is installed at the center of the sealing mechanism 1, and the outer filtering mechanism 2 is installed on the outer side of the inner filtering mechanism 3. The lower end of the inner filtering mechanism 3 is connected to the transmission mechanism 4; Figure 3 As shown, the inner filtering mechanism 3 includes a central rotating seat 31, a rotating cylinder 34 is installed at the axial position of the central rotating seat 31, and the rotating cylinder 34 drives the central rotating seat 31 to rotate. A top elastic cover 33 is installed on the top of the upper end of the rotating cylinder 34. The top elastic cover 33 is used to prevent the feed from hitting the gear lever 37 when it falls. A fixing column 35 is connected to the inside of the rotating cylinder 34. An elastic filter screen 32 is evenly installed on the top of the outer edge of the central rotating seat 31. The elastic filter screen 32 is a cone-shaped structure, and the bottom of the elastic filter screen 32 is connected to the central rotating seat 31. Figure 4 As shown, the top of the elastic filter 32 is connected to a plurality of levers 37, the levers 37 penetrate and connect the rotating cylinder 34, the levers 37 are slidably connected to the rotating cylinder 34 through the limiting grooves 39, and the inner part of the limiting grooves 39 is located at the upper end of the levers 37 and connected to the tension spring 38, as shown in FIG. Figure 6 and Figure 7 As shown, a guide groove 310 is provided on the fixed column 35, and the inner end of the shift rod 37 is slidably arranged in the guide groove 310. The guide groove 310 includes an inclined end, a first horizontal section, a vertical end and a second horizontal section which are sequentially connected end to end. The guide groove 310 is used to enable the shift rod 37 to be in a pocket state when receiving feed while driving the elastic filter 32 to rotate, thereby softly receiving the feed to avoid feed crushing. At the same time, the shaking of the elastic filter 32 itself is used to make impurities fall off. When the rotating cylinder 34 rotates, the shift rod 37 is quickly pulled up by the tension spring 38, so that the shift rod 37 pulls the elastic filter 32 to quickly unfold it, and the elastic force is used again to separate the impurities and the feed.

[0029] like Figure 1 As shown, the outer filtering mechanism 2 includes a rotating frame 21, which surrounds the outer side of the elastic filter 32. An outer filter 23 is installed on one side of the rotating frame 21 corresponding to the elastic filter 32. When the elastic filter 32 ejects the feed, the feed falls and cooperates with the outer filter 23, so that the feed lands softly again to avoid being broken. The lower end of the rotating frame 21 is connected to a rotating seat 22, and a discharge port 25 is provided between the rotating frame 21 and the rotating seat 22. The discharge port 25 connects the rotating frame 21 and the sealing cylinder 11. A top air guide seat 24 is installed on the inner side surface of the sealing mechanism 1 located at the top of the rotating frame 21. The top air guide seat 24 guides the wind blown from the bottom. Under the action of the wind and the top air guide seat 24, it can not only ensure the buffering of the feed, but also drive the wind to blow impurities to the outer filter 23 and the elastic filter 32 for screening and collection.

[0030] The transmission mechanism 4 includes a pressure cone gear cylinder 41, which is installed at the bottom of the rotating cylinder 34. One side of the pressure cone gear cylinder 41 is connected with an adjusting cone cylinder 42. The adjusting cone cylinder 42 transmits the power of the motor 43 to the pressure cone gear cylinder 41. The inside of the adjusting cone cylinder 42 is connected to the coupling of the power shaft of the motor 43 through an adjusting spring 46. A transmission sprocket group 44 is installed on the rotating cylinder 34 on the upper side of the pressure cone gear cylinder 41. The output end of the transmission sprocket group 44 is connected to a driving gear 45, such as Figure 1 As shown, the driving gear 45 is fixed on the inner fixed cylinder 17 through a pin shaft. Figure 5 As shown, the driving gear 45 is externally matched with the rotating seat 22, and a gear ring matching the driving gear 45 is formed on the rotating seat 22, as shown in FIG. Figure 3 As shown, a bottom spring 36 is installed between the bottom of the pressure bevel gear cylinder 41 and the inner fixed cylinder 17 .

[0031] The sealing mechanism 1 comprises a sealing cylinder 11, a base 12 is installed at the lower end of the sealing cylinder 11, a feeding funnel 13 is connected to the upper end of the sealing cylinder 11, an air inlet pipe 14 is installed at the bottom of the sealing cylinder 11, a first dust outlet pipe 15 is installed at the end of the sealing cylinder 11 away from the air inlet pipe 14, and a second dust outlet pipe 16 is installed at the lower side of the first dust outlet pipe 15. Figure 1 As shown, the feeding end of the second dust outlet pipe 16 is fixed to the lower side of the central rotating seat 31 inside the inner fixed cylinder 17 , a partition is provided between the lower side of the central rotating seat 31 and the inner fixed cylinder 17 , and a scraper is installed on the lower end surface of the central rotating seat 31 .

[0032] like Figure 4 As shown, the elastic filter 32 is connected to the central rotating seat 31 and the gear lever 37 by screws, and the upper and lower ends of the tension spring 38 are fixedly connected to the end surfaces of the gear lever 37 and the rotating cylinder 34 respectively.

[0033] The outer filter screen 23 is connected to the rotating frame 21 by screws. A through hole is provided between the rotating frame 21 and the outer filter screen 23. The cross section of the outer filter screen 23 is a cone-shaped structure that is wide at the top and narrow at the bottom.

[0034] The pressure bevel gear cylinder 41 is connected to the rotating cylinder 34 by bolts, the pressure bevel gear cylinder 41 is slidably connected to the adjusting cone cylinder 42, and the adjusting spring 46 is connected to the adjusting cone cylinder 42 and the coupling by welding.

[0035] In summary, after the high-pressure gas passes through the intake pipe 14, the high-pressure wind blows from between the rotating seat 22 and the inner fixed cylinder 17 to between the outer filter screen 23 and the elastic filter screen 32, and then guides through the top wind guide seat 24 to blow to the top surface of the outer filter screen 23 and the elastic filter screen 32. At this time, the feed raw materials are introduced through the feed funnel 13, and the feed falls on the elastic filter screen 32. The impurities are shaken off. At this time, the elastic filter screen 32 is driven by the gear lever 37 to form a pocket shape, and the feed is softly connected. At the same time, the motor 43 drives the central rotating seat 31 and the elastic filter screen 32 to rotate through the adjusting cone cylinder 42 and the pressure cone gear cylinder 41. The elastic filter screen 32 is in the feed transmission process. During the process, the feed is shaken and the impurities on the feed are shaken off. After the impurities fall into the space between the central rotating seat 31 and the inner fixed cylinder 17, they are scraped into the second dust outlet pipe 16 by the scraper at the lower end of the central rotating seat 31 for discharge. The elastic filter 32 continues to rotate. When the gear lever 37 reaches the vertical section of the guide groove 310, it is instantly bounced up by the tension spring 38, and the elastic filter 32 is instantly unfolded. The feed is shaken and bounced to the outer filter 23 on the outside, and the impurities are softly shaken again and fall along the inclined surface of the outer filter 23. The high-pressure gas at the bottom buffers the feed to avoid hard landing, and the feed falls into the soft frame inside the base 12 for collection or discharge.

[0036] When a large amount of feed enters, the elastic filter 32 is impacted by more feed, so that the weight increases, and the elastic filter 32, the rotating cylinder 34, and the top elastic cover 33 move downward as a whole. During the downward movement, the pressure cone gear cylinder 41 squeezes the adjusting cone cylinder 42, so that the adjusting cone cylinder 42 is deformed (such as Figure 8 to Figure 9 As shown in the figure, the rotation speed of the rotating cylinder 34 becomes faster through the speed change of the pressure cone gear cylinder 41 and the regulating cone cylinder 42, and the rotation speed of the central rotating seat 31, the elastic filter 32 and the rotating seat 22 all become faster, thereby improving the screening efficiency of the feed and avoiding the impact of the subsequent feed on the previous feed.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
