TECHNICAL FIELD
[0001] The utility model relates to the field of calf feeding technology, and specifically relates to a calf feeding equipment. BACKGROUND
[0002] For a cow farm of intensive production mode, the calf is the reserve force source of the whole cow group, and has very important significance in selection, breeding, production, variety improvement and breeding benefit, so its feeding management is particularly important. At present, in the process of calf feeding, in order to improve the growth efficiency of the calf, premix granules with high nutrient absorption and high reproductive capacity are used. Because the premix granules are usually directly placed in the cow house for the breeding personnel to directly take and feed the calf, but the air in the cow house usually contains a large amount of hair and other filamentous impurities, so the premix granules stored in the cow house will also mix the hair and other filamentous impurities, and the breeding personnel is not easy to find and clean the hair and other filamentous impurities mixed in the premix granules when feeding, if the calf directly eats the premix granules mixed with the hair and other filamentous impurities, it may cause indigestion of the calf, and further cause the calf to be malnourished due to decreased appetite, affecting the normal growth of the calf.
[0003] At present, there are pasture companies that have developed feeding devices that can remove hair and other filamentous impurities from premix granules, which specifically set a guide table on one side of the feeding device and a dust collection fan on the other side. After the premix granules are put into the feeding device, the premix granules fall on the guide table and continue to fall into the trough, while the dust collection fan sucks the hair and other filamentous impurities floating above the guide table to one side where it is located for collection, achieving the removal of hair and other filamentous impurities from the premix granules.
[0004] In the above technical solution, the dust suction fan mainly realizes suction of the floating silk-like impurities such as cow hair in the space above the guide table by sucking the air in the space, but not all the silk-like impurities such as cow hair will float above the guide table, and some of the silk-like impurities such as cow hair will always fall on the guide table without being lifted, and with the continuous falling of the premixed granular material on the guide table, the silk-like impurities such as cow hair are always pressed on the guide table and cannot be lifted, and finally still slide down with the premixed granular material to the trough. In addition, the dust suction fan and the guide table are arranged on both sides with a certain distance between them, and the silk-like impurities such as cow hair need to be sucked to the other side to be removed. If the power of the dust suction fan is too small, it is difficult to completely suck the silk-like impurities such as cow hair, especially the silk-like impurities such as cow hair that are not lifted. If the power of the dust suction fan is too large, part of the premixed granular material may be sucked away, causing raw material loss. It is difficult to determine the appropriate power of the dust suction fan that can ensure good suction of the silk-like impurities such as cow hair and avoid suction of the premixed granular material. In summary, the above technical solution has a general effect on removing the silk-like impurities such as cow hair from the premixed granular material, and the silk-like impurities such as cow hair still have a high probability of falling into the trough, resulting in the intake of the silk-like impurities such as cow hair by the calf.

[0032] The technical solutions of the present application will be described below in conjunction with the drawings.
[0033] Please refer to Figure 1 , which is a cross-sectional structure schematic diagram of the calf feeding device of the first embodiment of the present application. As Figure 1 shown, the calf feeding device of the first embodiment includes a trough 100 and a feeding device 200, the feeding device 200 is arranged above the trough 100, the feeding personnel puts the feed into the feeding device 200, and the feeding device 200 further transports the feed into the trough 100 for the calf to eat; wherein the feeding device 200 specifically includes a shell 210, a filter plate 220, an elastic support mechanism 230 and an electrostatic generator 240, the electrostatic generator 240 is connected to the filter plate 220 to make the filter plate 220 have static electricity, and then the filter plate 220 has electrostatic adsorption capacity to realize adsorption of hair and other filamentous impurities; and the shell 210 includes an upper opening 211, a lower opening 212 and a material falling channel 213 communicating the upper opening 211 and the lower opening 212, the filter plate 220 is arranged in the material falling channel 213, and the fixed end 221 of the filter plate 220 is rotatably connected to the inner wall of the material falling channel 213, the elastic support mechanism 230 is arranged in the material falling channel 213 and elastically supports the filter plate 220, so that the movable end 222 of the filter plate 220 abuts against the inner wall of the material falling channel 213, at this time the filter plate 220 divides the material falling channel 213, and when the filter plate 220 is subjected to downward force, it can overcome elastic work and swing downward, so that the movable end 222 of the filter plate 220 is separated from the inner wall of the material falling channel 213, that is, a material falling opening 260 is formed between the movable end 222 of the filter plate 220 and the inner wall of the material falling channel 213, so that the material falling channel 213 can transport the feed from top to bottom.
[0034] The calf feeding device of the first embodiment is mainly used for removing the silk-like impurities such as cow hair mixed in the feed, for example, premix granules. The working principle of the calf feeding device is as follows: the feeding personnel first starts the electrostatic generator 240, and the filter plate 220 is electrified through the electrostatic generator 240, so that the filter plate 220 has the function of electrostatic adsorption, and the silk-like impurities such as cow hair are easily electrostatically adsorbed, and the premix granules are not easily electrostatically adsorbed, even if there is a certain electrostatic adsorption, the premix granules can overcome the electrostatic adsorption force and leave the filter plate 220 by their own gravity. When the premix granules have not fallen on the filter plate 220, the movable end 222 of the filter plate 220 is abutted to the inner wall of the dropping channel 213 under the support of the elastic support mechanism 230, so that the filter plate 220 blocks the dropping channel 213. When the feeding personnel puts the premix granules into the dropping channel 213 from the upper opening 211 of the shell 210, the premix granules first fall on the filter plate 220 and accumulate on the filter plate 220. In this process, the silk-like impurities such as cow hair mixed in the premix granules are electrostatically adsorbed by the filter plate 220. When the premix granules on the filter plate 220 accumulate to a certain extent, the pressure of the filter plate 220 on the elastic support mechanism 230 increases significantly, and the filter plate 220 swings downward to overcome the elastic work, so that the movable end 222 of the filter plate 220 is no longer abutted to the inner wall of the dropping channel 213, that is, the movable end 222 of the filter plate 220 is separated from the inner wall of the dropping channel 213, so that the falling opening 260 is formed between the movable end 222 of the filter plate 220 and the dropping channel 213, and the premix granules continue to fall downward through the falling opening 260 and fall into the feeding trough 100, while the silk-like impurities such as cow hair are electrostatically adsorbed and remain on the filter plate 220, thereby realizing the separation of the silk-like impurities such as cow hair mixed in the premix granules, avoiding the digestion disorder caused by the silk-like impurities such as cow hair eaten by the calf, and ensuring the normal growth of the calf.
[0035] In the first embodiment, after the premix granules enter the feeding device 200, they must first pass through the filter plate 220 and may be temporarily stopped on the filter plate 220. Therefore, the silk-like impurities such as cow hair mixed in the premix granules must also pass through the filter plate 220 and may be temporarily stopped on the filter plate 220, so that the difficulty of electrostatic adsorption of the silk-like impurities such as cow hair by the filter plate 220 is greatly reduced, and the adsorption effect of the filter plate 220 on the silk-like impurities such as cow hair is improved, thereby avoiding the silk-like impurities such as cow hair falling into the feeding trough 100 with the premix granules and avoiding the calf eating the silk-like impurities such as cow hair. It should be noted that when the movable end 222 of the filter plate 220 abuts to the inner wall of the dropping channel 213 in the first embodiment of the present application, the entire outer periphery of the filter plate 220 is in contact with the inner wall of the dropping channel 213, thereby blocking and plugging the dropping channel 213.
[0036] Please refer to Figures 2-4This is a schematic diagram illustrating the positional relationship between the filter plate 220 and the material discharge channel 213 in the second embodiment of this application. In the first aspect, as... Figures 2-4 As shown, the inner wall of the feeding channel 213 is vertically straight and / or inclinedly straight to guide the feed downwards and reduce processing costs. In this second embodiment, the cross-sectional structure of the feeding channel 213 can specifically be a structure where the upper opening 211 is smaller than the lower opening 212 due to the inclined straight inner walls on both sides; or a structure where the upper opening 211 is larger than the lower opening 212 due to the inclined straight inner walls on both sides; or a structure where the upper opening 211 and lower opening 212 have the same width due to the vertical straight inner walls on both sides; or a structure where one side has an inclined straight inner wall and the other side has a vertical straight inner wall. It should be noted that in this second embodiment, the straight inner wall of the feeding channel 213 refers to its straight appearance in the cross-sectional plane, and does not limit the specific shape of the inner wall of the feeding channel 213 in the circumferential direction. The circumferential shape of the feeding channel 213 can be circular, arc-shaped, square, etc.
[0037] Secondly, such as Figures 2-4 As shown, in this second embodiment, the position where the movable end 222 of the filter plate 220 abuts against the inner wall of the discharge channel 213 is located at the point where the movable end 222 of the filter plate 220 is tangent to the inner wall of the discharge channel 213, or lower than the point where the movable end 222 of the filter plate 220 is tangent to the inner wall of the discharge channel 213, so that the movable end 222 of the filter plate 220 can swing downward, satisfying the condition that a discharge port 260 is formed between the movable end 222 of the filter plate 220 and the inner wall of the discharge channel 213.
[0038] Furthermore, a third embodiment is obtained by improving upon the second embodiment, please refer to [reference needed]. Figure 5 This is a schematic diagram of the contact between the movable end 222 of the filter plate 220 and the inner wall of the material discharge channel 213 in the third embodiment. Figure 5 As shown, the movable end 222 of the filter plate 220 is lower than the fixed end 221, so that the premixed pellets can gather at the movable end 222 of the filter plate 220 after falling onto the filter plate 220. In this way, when the discharge port 260 is formed between the movable end 222 of the filter plate 220 and the inner wall of the discharge channel 213, the premixed pellets can immediately slide from the filter plate 220 into the discharge port 260. This not only ensures the removal of fibrous impurities such as cow hair, but also improves feeding efficiency and reduces the residue of premixed pellets on the filter plate 220.
[0039] In the fourth embodiment of this application, the elastic support mechanism 230 is a torsion spring disposed at the fixed end 221 of the filter plate 220. Since the fixed end 221 of the filter plate 220 is rotatably connected to the discharge channel 213, the torsion spring supports the rotation of the filter plate 220. In this fourth embodiment, the torsion spring supports the filter plate 220 upwards with torque until the movable end 222 of the filter plate 220 abuts against the inner wall of the discharge channel 213. When the premixed granules fall onto the filter plate 220, the pressure exerted by the filter plate 220 on the torsion spring increases. The filter plate 220 overcomes the torque of the torsion spring and swings downwards, forming a discharge port 260 between the movable end 222 of the filter plate 220 and the inner wall of the discharge channel 213. In this fourth embodiment, the elastic support mechanism 230 uses a torsion spring, which has a simple structure and low cost.
[0040] Please refer to Figure 6 This is a schematic diagram showing the position of the elastic support mechanism 230 according to the fifth embodiment of this application. Figure 6 As shown, the elastic support mechanism 230 is located below the filter plate 220. The lower end of the elastic support mechanism 230 is rotatably connected to the inner wall of the material discharge channel 213, and the upper end of the elastic support mechanism 230 is rotatably connected to the filter plate 220. The elastic support mechanism 230 can elastically extend and retract. In this fifth embodiment, the elastic support mechanism 230 is in an extended state due to its own elasticity, supporting the filter plate 220 upwards until the movable end 222 of the filter plate 220 abuts against the inner wall of the material discharge channel 213. When the premixed granules fall onto the filter plate 220, the pressure exerted by the filter plate 220 on the elastic support mechanism 230 increases. The filter plate 220 overcomes the elastic force of the elastic support mechanism 230 and swings downwards. The elastic support mechanism 230 is compressed, and the movable end 222 of the filter plate 220 forms a discharge port 260 between itself and the inner wall of the material discharge channel 213. During the downward swing of the filter plate 220, the elastic support mechanism 230 as a whole will also produce an adaptive swing.
[0041] In this fifth embodiment, the elastic support mechanism 230 can be a hydraulic cylinder, a gas spring 233, or similar mechanism, but the cost may be high. Therefore, a sixth embodiment is obtained by further improving upon the fifth embodiment. Please refer to the sixth embodiment. Figure 7 This is a structural schematic diagram of the elastic support mechanism 230 in the sixth embodiment. Figure 7As shown, the elastic support mechanism 230 includes a base 231, a support rod 232, and a spring 233. The base 231 has a telescopic cavity 234, and the spring 233 is located within the telescopic cavity 234. Part of the support rod 232 extends into the telescopic cavity 234 and connects to the spring 233. Another part of the support rod 232 extends out of the telescopic cavity 234 to be rotatably connected to the filter plate 220. The spring 233 elastically supports the support rod 232 upwards, which in turn supports the filter plate 220. When premixed granules accumulate on the filter plate 220, the filter plate 220 is compressed by the support rod 232 against the spring 233, causing the filter plate 220 to swing downwards. The structure is simple and the cost is low.
[0042] Please refer to Figure 8 This is a schematic diagram of the filter plate 220 in the seventh embodiment. Figure 8 As shown, the upper surface of the filter plate 220 has a concave-convex structure 223 to further prevent filamentous impurities such as cow hair from sliding off the filter plate 220, and to further ensure that filamentous impurities such as cow hair remain on the filter plate 220, thus preventing calves from ingesting filamentous impurities such as cow hair. Specifically, in this seventh embodiment, the concave-convex structure 223 on the upper surface of the filter plate 220 can be wavy.
[0043] In this embodiment, the filter plate 220 adsorbs filamentous impurities such as cow hair onto its upper side by electrostatic adsorption. After the feeder has finished feeding the premixed pellets into the feeding device 200, it is necessary to manually clean the filamentous impurities such as cow hair on the filter plate 220. At this time, it is necessary to reach in through the upper opening 211 of the outer shell 210 of the feeding device 200 to clean it, which is inconvenient.
[0044] Therefore, the calf feeding equipment of the eighth embodiment of this application also includes a scraping mechanism 250, please refer to Figure 9 This is a schematic diagram of the scraping mechanism 250 in the eighth embodiment of this application. Figure 9As shown, the calf feeding equipment also includes a scraping mechanism 250 located above the filter plate 220. The scraping mechanism 250 includes a drive unit 251, a push rod 252, and a scraping part 253. The scraping part 253 is located at the end of the push rod 252 and is slidably connected to the filter plate 220. The drive unit 251 is connected to the push rod 252 and drives the push rod 252 to extend and retract (the drive unit 251 can be a servo motor) so that the scraping part 253 moves along the filter plate 220. During the process of the scraping part 253 moving along the filter plate 220, the filamentous impurities such as cow hair on the upper side of the filter plate 220 can be scraped off. In specific usage, after the calf finishes eating, the scraping mechanism 250 is activated. The scraping mechanism 250 pushes the scraping part 253 to move via the push rod 252, so it also exerts downward pressure on the filter plate 220 during the process, which can push the filter plate 220 to swing downward, so that a discharge port 260 is formed between the movable end 222 of the filter plate 220 and the inner wall of the discharge channel 213. When the scraping part 253 moves from the fixed end 221 of the filter plate 220 to the movable end 222, it can push filamentous impurities such as cow hair into the discharge port 260, so that the scraped filamentous impurities such as cow hair fall into the feed trough 100, and then the feeder can collect them directly in the feed trough 100. The operation is convenient.
[0045] In this eighth embodiment, specifically, the scraping part 253 includes a sliding head and a scraping head. The sliding head is slidably connected to the upper side of the filter plate 220, and the scraping head abuts against the upper side of the filter plate 220. A groove can be provided on the upper side of the filter plate 220 for the sliding head to slide.
[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
