Description

Technical Field

[0001] This utility model relates to the field of dairy farming technology, specifically to a hay shredder for dairy farming. Background Technology

[0002] Dairy cows have a unique digestive system, where rumen microbial fermentation relies on the breakdown of forage structure. Crushing the forage breaks down the fibers, increasing the surface area for microbial contact, which facilitates fermentation, improves digestibility, and allows dairy cows to better absorb nutrients.

[0003] Utility model patent CN221979590U discloses a hay shredder for dairy farming. It consists of a fixed platform forming the basic support structure. An electrical control box is installed on the upper left front part of the fixed platform, while the main body of the device is fixed at the rear. A feeding trough connects the front end of the main body of the device to the upper right side of the fixed platform for material conveying. A hay shredding head is connected to the upper left side of the outer surface of the main body of the device, and a discharge port is provided on the upper left side of the hay shredding head. Notably, an adjustment mechanism is also provided on the upper left side of the outer surface of the hay shredding head. Four support legs are connected to the lower end of the fixed platform, and a fixing frame is inserted and fixed to the lower outer surface of the four support legs.

[0004] However, the existing equipment has a relatively limited function, only capable of simple crushing of forage, failing to fully break down the fiber structure of the forage, resulting in limited improvement in forage softness. Furthermore, during the crushing process, the existing equipment struggles to precisely control the degree of forage processing, unable to adjust the size and texture of the forage according to different growth stages and milk production needs of dairy cows. Simultaneously, the existing technology lacks an effective mechanism for mixing additives into the forage, leading to uneven distribution of additives and making it difficult to ensure that dairy cows ingest the appropriate amount of nutritional additives with each bite. This hinders farmers from accurately controlling feeding amounts, thus impacting the improvement of farming efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides the following technical solution: A hay shredder for dairy farming, comprising a support unit, the support unit including a support base plate, a support shell disposed on the support base plate, and a shredding unit disposed on the support shell; the shredding unit includes a first shredding transmission roller and a second shredding transmission roller rotatably disposed on the support shell; the first shredding transmission roller is disposed on the second shredding transmission roller via a shredding transmission belt, and the second shredding roller and the first shredding roller are rotatably disposed on the side near the second shredding transmission roller; a first shredding gear is fixedly disposed on the first shredding roller, and a second shredding gear is fixedly disposed on the second shredding roller, the first shredding gear meshing with the second shredding gear; the second shredding gear is connected to the second shredding transmission roller via the first shredding transmission belt; the first shredding roller is disposed on a shredding shaft via the second shredding transmission belt; a shredding blade is rotatably disposed on the shredding shaft; a first shredding dispersion shaft and a second shredding dispersion shaft are rotatably disposed below the shredding shaft; the first shredding dispersion shaft and the second shredding dispersion shaft are disposed on the shredding shaft via a third shredding transmission belt.

[0006] Furthermore, the supporting shell is provided with a spraying part for spraying feed additives. The spraying part includes a spraying water tank, which is installed on the inlet chamber of the spraying pressurizing cylinder through a spraying inlet pipe. The inlet chamber is connected to the outlet chamber. A spraying sliding plug is slidably installed in the outlet chamber. The inside of the spraying sliding plug is a hollow structure. A second spraying ball plug is slidably installed inside the spraying sliding plug. The second spraying ball plug is installed on the spraying sliding plug through a second spraying return spring. An outlet hole is provided on the side wall of the spraying sliding plug.

[0007] Furthermore, a spraying sliding ball plug is slidably disposed in the liquid inlet chamber. The spraying sliding ball plug is disposed in the spraying pressurizing cylinder through a spraying reset spring. The liquid outlet chamber of the spraying pressurizing cylinder is connected to the spraying liquid outlet box. The spraying liquid outlet box is disposed on the supporting shell through multiple spraying liquid outlet pipes.

[0008] Furthermore, the outer walls of the first and second kneading rollers are provided with raised strips, and grooves are provided at the relative positions of the raised strips. The raised strips and the grooves cooperate to knead the forage.

[0009] Furthermore, the kneading shaft is fixedly mounted on the output shaft of the kneading motor, and the kneading motor is fixedly mounted on the support housing.

[0010] Furthermore, the kneading blades are arranged in a circular array along the rotation center of the kneading axis.

[0011] Furthermore, a partition plate is detachably provided in the middle of the supporting shell via a sliding groove, and the partition plate is provided with multiple filter holes.

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. Optimize the quality of forage processing; This utility model uses a kneading motor to drive the kneading shaft and kneading blades to rotate, and in conjunction with the protrusions and grooves on kneading roller one and kneading roller two, it can crush the forage, which can completely destroy the fiber structure of the forage, making the originally rough and hard forage softer, greatly improving the chewability and digestibility of the forage, helping dairy cows to better absorb nutrients, promoting their growth and development, and improving the quality and quantity of milk production.

[0014] 2. Precise control of processing particle size: Based on actual feeding needs, isolation plates with different filter pore sizes can be installed on the supporting shell to filter the forage after kneading and cutting, precisely controlling the size of the forage falling into subsequent processes, meeting the special requirements of dairy cows for forage particle size at different growth stages and milk production periods, and realizing the refinement and personalization of forage processing.

[0015] 3. Uniformly mix feed additives; the spray cylinder drives the spraying sliding plug to slide back and forth within the spraying pressurization cylinder, achieving quantitative intake and precise spraying of feed additives. During the rotation and mixing of the feed by the first and second kneading and dispersing shafts, the additives are fully mixed with the feed, ensuring that every bite of feed for dairy cows contains an appropriate amount of additives, meeting their nutritional needs at different stages of growth and milk production. This helps farmers accurately control the amount of feed given, significantly improving farming efficiency.

[0016] 4. Improve overall equipment performance: Through the coordinated operation of various components such as the kneading conveyor belt and kneading gear, the integrated continuous operation from feed conveying, kneading, cutting, filtering to additive mixing is realized. This not only improves the working efficiency of the equipment, but also reduces manual intervention, lowers labor intensity, and enhances the practicality and stability of the equipment, providing strong technical support for large-scale dairy farming.

The partition plate 4 is provided with multiple filter holes for filtering the forage that has been kneaded by the kneading section 2.

[0030] like Figures 1 to 8 As shown, this utility model discloses a hay shredder for dairy farming. Its working principle is as follows: The hay to be processed is placed on the shredding conveyor belt 201. The operator turns on the shredding motor 211. The rotation of the shredding motor 211 drives the shredding shaft 210 to rotate, which in turn drives the shredding blades 215 to rotate. Simultaneously, the rotation of the shredding shaft 210 drives the shredding roller 203 to rotate via the second shredding conveyor belt 208. The rotation of the first shredding roller 203 drives the second shredding gear 206 to rotate via the first shredding gear 205, which in turn drives the shredding roller... As the second cylinder 204 rotates, the second kneading gear 206 rotates simultaneously, driving the second kneading conveyor roller 214 via the first kneading conveyor belt 207, which in turn drives the second kneading conveyor belt 201 to rotate. The rotation of the kneading conveyor belt 201 transports the forage on the kneading conveyor belt 201 to between the rotating first kneading roller 203 and the second kneading roller 204. The protrusions and grooves on the first kneading roller 203 and the second kneading roller 204 crush the forage, making the texture of the forage softer and breaking down the fiber structure, making the originally rough and hard forage easier to chew and digest.

[0031] After being crushed by the first crushing roller 203 and the second crushing roller 204, the forage falls into the crushing shaft 210. The rotating crushing shaft 210 drives the crushing blade 215 to cut and crush the forage at this position. According to the actual feeding needs, the isolation plate 4 with different filter hole diameters is installed on the support shell 301. At this time, the filter hole on the isolation plate 4 filters the forage and controls the size of the forage falling into the first crushing and dispersing shaft 212. While the crushing shaft 210 is rotating, the crushing conveyor belt 3 209 drives the first crushing and dispersing shaft 212 and the second crushing and dispersing shaft 213 to rotate, which stirs and disperses the forage falling into this position.

[0032] At this time, the spray cylinder 107 is activated, and the spray cylinder 107 drives the spray sliding plug 106 to slide back and forth inside the spray pressurizing cylinder 103. When the spray sliding plug 106 slides towards the spray cylinder 107, the chamber formed by the spray sliding plug 106 and the spray pressurizing cylinder 103 near the spray return spring 105 gradually becomes negative pressure. At this time, the feed additive in the spray water tank 101 flows into the chamber from the spray water tank 101 through the spray inlet pipe 102, pushing the spray sliding ball plug 104. When the spray sliding plug 106 moves towards the spray return spring 105, the spray sliding ball plug 104 blocks the channel formed by the spray sliding ball plug 104 and the spray pressurizing cylinder 103, and the spray sliding plug 106 and the spray pressurizing cylinder 103 approach the spray... The pressure in the chamber formed on one side of the return spring 105 increases. At this time, the pressure pushes the spray ball plug 108 to slide. The sliding spray ball plug 108 compresses the spray return spring 109, causing the feed additive in the chamber to flow out from the liquid outlet hole on the side wall of the spray sliding plug 106 into the spray liquid outlet tank 110, and finally flow into the support shell 301 from the spray liquid outlet pipe 111. The feed additive is sprayed onto the hay at the kneading and dispersing shaft 212. The rotating kneading and dispersing shaft 212 and kneading and dispersing shaft 213 make the feed additive and hay fully mixed, which can ensure the balanced nutrition ingested by dairy cows, so that each bite of hay contains an appropriate amount of additives to meet the nutritional needs of different stages of growth and milk production. This helps farmers to accurately control the amount of feed and improve breeding efficiency.
