Description

Technical Field

[0001] This invention relates to the field of livestock feeding technology, and more specifically, to a feed mixing and feeding device for raising ruminant calves. Background Technology

[0002] In ruminant farming, the rearing of young animals is of paramount importance, as their healthy growth directly affects the profitability of the entire industry. Feed mixing and feeding is a key step in the rearing process, but existing feed mixing and feeding devices have many shortcomings.

[0003] Traditional feed mixing and feeding devices have limited functionality and are not precise enough in processing solid feed. Solid feed particles are often large, which ruminant calves, whose digestive systems are not yet fully developed, cannot fully digest and absorb, thus affecting their growth and development. Moreover, when mixing solid and liquid nutrients, the mixing effect is poor, failing to achieve uniform integration and resulting in unbalanced nutrition for the calves. From the perspective of feed characteristics, the feed required for ruminant calves needs to be easily digestible, such as containing more than 20% crude protein and moderate energy, in order to meet their nutritional needs for rapid growth. At the same time, to improve the appeal of the feed to the calves, flavoring agents such as molasses are often added. However, existing devices cannot ensure that these special components are evenly distributed in the feed during the mixing process. Furthermore, the process of moving and feeding the feed after mixing is cumbersome, consuming manpower and time, and reducing breeding efficiency.

[0004] In view of this, we propose a feed mixing and feeding device for raising ruminant offspring. Summary of the Invention

[0005] The purpose of this invention is to provide a feed mixing and feeding device for raising ruminant calves, in order to solve the technical problems of traditional feed mixing and feeding devices having limited functions, poor processing and mixing effects for solid and liquid feeds, and cumbersome feed movement and feeding, which consumes manpower and time and reduces breeding efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feed mixing and feeding device for raising ruminant calves, comprising a feeding mechanism and a processing mechanism, wherein the feeding mechanism and the processing mechanism are connected; The feeding mechanism includes a moving component, a support above the moving component, a protective shell connected to the support, an outer shell assembly inside the protective shell, a feeding shell connected to the outer shell assembly, a discharge valve, and a discharge assembly, wherein the discharge valve is connected to the outer shell assembly, and the discharge assembly is located below the outer shell assembly.

[0007] In high-speed operation mode, the crushing component extends due to the centrifugal force generated by the high-speed operation of the equipment, which can fully crush the input solid feed. After fine crushing, the feed particles become smaller and the surface area increases, which is more conducive to the full contact between the digestive enzymes of the pups and the feed, thereby improving the digestibility of the feed and ensuring that the pups can obtain more nutrients from the feed to promote their healthy growth. In medium-speed operation mode, a complex flow path can be formed during the mixing process, allowing the solid feed and liquid nutrient agents to fully contact and penetrate each other, thereby achieving uniform mixing. The uniformly mixed feed can ensure that the pups ingest a balanced amount of nutrients. After mixing is completed, the low-speed operation mode is started to move the equipment.

[0011] Preferably, the discharge assembly includes reinforcing ribs, and a discharge shell is fixedly connected above the reinforcing ribs; The reinforcing rib is fixedly connected to the bottom of the protective shell, and the discharge shell is located below the discharge valve. The discharge shell adopts an inclined design.

[0012] Preferably, the adjusting assembly includes a sliding sleeve, an anti-detachment plate is slidably connected inside the sliding sleeve, a sliding rod is fixedly connected to one side of the anti-detachment plate, a first spring is provided inside the sliding sleeve, the two ends of the first spring are fixedly connected to the anti-detachment plate and one side of the inner wall of the sliding sleeve, the other end of the sliding rod is fixedly connected to a first counterweight, and a pulley is fixedly connected to the other side of the first counterweight.

[0013] Preferably, one side of the sliding sleeve is fixedly connected to the outer wall of the mounting sleeve, the outer wall of the pulley overlaps with the upper part of the inner wall of the mixing drum, the upper part of the inner wall of the mixing drum adopts a conical inclined surface design, the sliding sleeve is horizontally arranged above the isolation plate, and the outer wall of the sliding sleeve overlaps with the limiting plate.

[0014] Preferably, the crushing assembly includes a telescopic crushing rod with an irregular surface. The inner wall of the telescopic crushing rod is fixedly connected to one end of the stirring rod, and the outer wall of the telescopic crushing rod is fixedly connected to an isolation sleeve. A second spring is provided inside the isolation sleeve.

[0015] Preferably, the two ends of the second spring are fixedly connected to the isolation sleeve and the stirring rod, respectively. The stirring rod adopts a transverse U-shaped design. The other end of the telescopic crushing rod is fixedly connected to the second counterweight, and the other side of the second counterweight is arc-shaped. The isolation sleeve is fixedly connected to the outside of the drive rod.

[0016] Preferably, the cleaning assembly includes a second sealing sleeve, the inner wall of which is fixedly connected with a plurality of support blocks, the plurality of support blocks being fixedly connected to the same connecting ring, and a plurality of scrapers being fixedly connected below the connecting ring; The second sealing sleeve is snapped into the mixing drum, and the outer wall of the second sealing sleeve is slidably connected to the protective shell. The lower part of the scraper overlaps with the lower part of the inner wall of the mixing drum.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the design of a crushing component, an adjusting component, and a shell component, allows the crushing component to extend with the centrifugal force generated by the high-speed operation of the equipment in high-speed mode. This enables the input solid feed to be fully crushed. The feed particles after fine crushing are smaller and have a larger surface area, which is more conducive to the full contact between the digestive enzymes of the pups and the feed, thereby improving the digestibility of the feed and ensuring that the pups can obtain more nutrients from the feed, promoting their healthy growth. In medium-speed operation mode, a complex flow path can be formed during the mixing process, allowing the solid feed and liquid nutrient agents to fully contact and penetrate each other, thereby achieving uniform mixing. The uniformly mixed feed ensures that the pups ingest a balanced amount of nutrients. After mixing is completed, the low-speed operation mode is started to move the equipment. Low-speed operation makes the equipment more stable during movement, reducing the impact of bumps and shaking on the internal structure of the equipment and the mixed feed.

[0018] 2. This invention also incorporates an adjustment component and a housing component. When the device is in high-speed operation, the drive rod synchronously drives the mounting sleeve and sliding sleeve to rotate at high speed. This causes the first counterweight to quickly pull the sliding rod outward under high-speed rotation. Simultaneously, under centrifugal force, the first counterweight overcomes the spring force of the first spring and slides radially outward along the sliding sleeve, causing the sliding rod to extend synchronously. This pushes the pulley to press against the conical inclined surface at the top of the mixing drum, thereby raising the height of the mixing drum. This allows the limiting plate to disengage from the sliding sleeve, ensuring that the mixing drum remains suspended and positioned during both high-speed and medium-speed operation. In low-speed operation, the No. 1 spring returns to its elasticity, the slide bar and pulley retract synchronously, the mixing drum moves downward under gravity, and the limiting plate re-engages into the outer groove of the sliding sleeve, realizing axial positioning and stable rotational conveying under low-speed conditions. This allows the device to achieve axial positioning switching of the mixing drum, radial extension and retraction of the telescopic crushing component, start and stop of the scraper cleaning component, and opening and closing of the discharge path by simply adjusting the speed of the driver. No additional independent control unit is required, which not only reduces the difficulty of using the device, but also significantly improves the consistency of structural response and operational reliability during multi-mode switching.

[0019] 3. This invention also improves mixing efficiency by designing a crushing component and a staggered stirring rod to increase the mixing coverage and force, enabling the solid and liquid feeds to be mixed evenly in a shorter time. This not only saves time and energy but also improves the efficiency of the entire feed feeding process, which is beneficial for large-scale breeding production. Attached Figure Description

[0022] like Figures 1 to 8 As shown, the present invention relates to a feed mixing and feeding device for raising ruminant calves, comprising a feeding mechanism 1 and a processing mechanism 2, wherein the feeding mechanism 1 and the processing mechanism 2 are connected. Feeding mechanism 1 includes a moving component 11, a support 12 located above the moving component 11, a protective shell 13 connected to the support 12, an outer shell assembly 14 located inside the protective shell 13, a feeding shell 15 connected to the outer shell assembly 14, a discharge valve 16, and a discharge assembly 17. The discharge valve 16 is connected to the outer shell assembly 14, and the discharge assembly 17 is located below the outer shell assembly 14. Processing mechanism 2 includes a driver 21, a drive rod 22 connected to the driver 21, a mounting sleeve 26 located outside the drive rod 22, three adjusting components 23 located outside the mounting sleeve 26, a crushing component 24, a cleaning component 25, and a bearing 27. The bearing 27 is located outside the drive rod 22, the crushing component 24 is located outside the drive rod 22, and the cleaning component 25 is located below the crushing component 24. In high-speed operation mode, the crushing component 24 rotates at high speed driven by the drive rod 22. Due to the telescopic crushing rod... A second counterweight 245 is provided at one end of 241, which causes the telescopic crushing rod 241 to extend radially under the action of centrifugal force. The second counterweight 245 drives the telescopic crushing rod 241 to slide outward against the elastic force of the second spring 244, and pulls the stirring rod 243 to slide into the telescopic crushing rod 241 until the stirring rod 243 is attached to the outside of the drive rod 22. As the telescopic crushing rod 241 runs at high speed, the irregular design on the surface of the telescopic crushing rod 241 will efficiently crush the solid feed and complete the processing of the solid feed. When switching to medium speed operation mode, the speed of the drive 21 decreases, the centrifugal force weakens, the second spring 244 restores its elastic force, pushes the telescopic crushing rod 241 to retract inward, and simultaneously drives the stirring rod 243 to slide out along the axial direction of the drive rod 22. At this time, the stirring rod 243 will perform multi-directional shearing and laminar flow mixing of solid feed and liquid nutrient agents through its unique shape design.In low-speed operation mode, the drive unit 21 further reduces its speed, and the first spring 234 drives the slide rod 233 and pulley 236 to retract. At this time, the pulley 236 no longer presses against the top of the mixing drum 141, and the mixing drum 141 moves downward under its own weight, causing multiple limit plates 143 to engage with the outside of the sliding sleeve 231. At this time, the drive rod 22 will drive the limit plates 143 and the mixing drum 141 to rotate through the sliding sleeve 231. The second sealing sleeve 251 and the scraper 254 are relatively fixed, thereby realizing the low-speed spiral conveying of the material in the mixing drum 141. After the device is moved to the designated position by the moving component 11, it is only necessary to open the discharge valve 16, and the mixed feed will be discharged along the discharge shell 172. In high-speed operation mode, the crushing component 24 rotates at high speed with the equipment. The centrifugal force generated during mixing expands the feed, thoroughly breaking down the solid feed particles. The smaller, more surface-area particles facilitate better contact between digestive enzymes and the feed, improving digestibility and ensuring the pups obtain more nutrients for healthy growth. In medium-speed mode, a complex flow path is created during mixing, allowing solid feed and liquid nutrients to fully contact and permeate, achieving uniform mixing. This ensures a balanced intake of nutrients for the pups. After mixing, a low-speed mode is activated to move the equipment smoothly, reducing the impact of bumps and vibrations on the internal structure and the mixed feed.

[0023] In an embodiment of the present invention, the upper part of the feeding mechanism 1 is fixedly connected to the bottom of four supports 12, the top of the four supports 12 is fixedly connected to the same protective shell 13, the outer shell assembly 14 is located inside the protective shell 13, the feeding shell 15 is slidably connected to the protective shell 13, one end of the feeding shell 15 passes through the protective shell 13 and is connected to the outer shell assembly 14, the bottom of the outer shell assembly 14 is connected to the discharge valve 16, the lower part of the protective shell 13 is fixedly connected to the discharge assembly 17, the output shaft of the driver 21 is fixedly connected to the drive rod 22, the outer wall of the drive rod 22 is fixedly connected to the mounting sleeve 26, the outer wall of the mounting sleeve 26 is fixedly connected to three adjustment assemblies 23, the outer wall of the drive rod 22 is fixedly connected to several crushing assemblies 24, the cleaning assembly 25 is located below the crushing assembly 24, there are several bearings 27, and the several bearings 27 are all sleeved outside the output shaft. The cleaning assembly 25 is snapped into the outer shell assembly 14. The crushed feed has a more uniform and delicate texture, the taste is improved, and it is more attractive to the young. This can stimulate the cubs' appetite, increase their food intake, ensure that the cubs get enough nutrition to meet their needs for rapid growth and development; Breaking solid feed into smaller particles lays a good foundation for subsequent mixing with liquid nutrients. Smaller solid particles can be more evenly dispersed in the liquid, reducing resistance during the mixing process and making mixing easier and more efficient. The adjustment component 23 overlaps with the inner wall of the outer shell component 14, and the driver 21 is fixedly connected to the top of the outer shell component 14.

[0024] In an embodiment of the present invention, the outer shell assembly 14 includes a stirring drum 141, an isolation plate 142 fixedly connected inside the stirring drum 141, a plurality of limiting plates 143 fixedly connected above the inner wall of the stirring drum 141, a first sealing sleeve 144 snapped onto the outside of the stirring drum 141, an inlet hole 145 opened inside the first sealing sleeve 144, the inlet hole 145 communicating with the feeding shell 15, the outer wall of the first sealing sleeve 144 slidingly connected to the protective shell 13, a driver 21 fixedly connected above the stirring drum 141, and a discharge valve 16 connected to the bottom end of the stirring drum 141. The discharge assembly 17 includes a reinforcing rib 171, with a discharge shell 172 fixedly connected above the reinforcing rib 171. The reinforcing rib 171 is fixedly connected below the protective shell 13. The discharge shell 172 is located below the discharge valve 16 and adopts an inclined design. By designing and adjusting the assembly 23 and the outer shell assembly 14, when the device is in high-speed operation, the drive rod 22 will synchronously drive the mounting sleeve 26 and the sliding sleeve 231 to rotate at high speed, causing the first counterweight 235 to quickly pull the sliding rod 233 to extend under high-speed rotation. At this time, under the action of centrifugal force, the first counterweight 235 overcomes the elastic force of the first spring 234 and slides radially outward along the sliding sleeve 231, causing the sliding rod 233 to extend synchronously, thereby pushing the pulley 236 to press against the conical inclined surface at the top of the mixing drum 141, thus raising the height of the mixing drum 141, causing the limiting plate 143 to disengage from the sliding sleeve 231, ensuring that the mixing drum 141 remains suspended and positioned when in high-speed and medium-speed operation. In low-speed operation, the first spring 234 restores its elastic force, and the sliding rod 233 and pulley 236 retract synchronously, raising the height of the mixing drum 141. As the device moves downward under the influence of gravity, the limiting plate 143 re-engages into the outer groove of the sliding sleeve 231, achieving axial positioning and stable rotational conveying under low-speed conditions. This allows the device to achieve axial positioning switching of the mixing drum 141, radial extension and retraction of the telescopic crushing component 24, start and stop of the scraper 254 cleaning component 25, and opening and closing of the discharge path by simply adjusting the speed of the driver 21. No additional independent control unit is required, which not only reduces the difficulty of using the device but also significantly improves the consistency of structural response and operational reliability during multi-mode switching.

[0025] In another embodiment of the present invention, the adjusting component 23 includes a sliding sleeve 231, an anti-detachment plate 232 slidably connected inside the sliding sleeve 231, a sliding rod 233 fixedly connected to one side of the anti-detachment plate 232, a first spring 234 disposed inside the sliding sleeve 231, the two ends of the first spring 234 being fixedly connected to one side of the anti-detachment plate 232 and the inner wall of the sliding sleeve 231 respectively, a first counterweight 235 fixedly connected to the other end of the sliding rod 233, and a pulley 236 fixedly connected to the other side of the first counterweight 235. One side of the roller 236 is fixedly connected to the outer wall of the mounting sleeve 26. The outer wall of the roller 236 overlaps with the upper part of the inner wall of the mixing drum 141. The upper part of the inner wall of the mixing drum 141 adopts a conical inclined surface design. The roller 231 is horizontally positioned above the isolation plate 142. The outer wall of the roller 231 overlaps with the limiting plate 143. By designing the crushing component 24 and the staggered design of the mixing rod 243, the mixing coverage area and mixing force are increased, which can mix solid and liquid feed evenly in a shorter time and improve mixing efficiency. This not only saves time and energy, but also improves the efficiency of the entire feed feeding process, which is beneficial to large-scale breeding production.

[0026] In another embodiment of the present invention, the crushing assembly 24 includes a telescopic crushing rod 241. The surface of the telescopic crushing rod 241 is irregularly designed. The inner wall of the telescopic crushing rod 241 is fixedly connected to one end of the stirring rod 243. The outer wall of the telescopic crushing rod 241 is fixedly connected to the isolation sleeve 242. A second spring 244 is provided inside the isolation sleeve 242. The two ends of the second spring 244 are fixedly connected to the isolation sleeve 242 and the stirring rod 243, respectively. The stirring rod 243 adopts a transverse U-shaped design. A second counterweight 245 is fixedly connected to the other end of the telescopic crushing rod 241. The other side of the second counterweight 245 is arc-shaped. The isolation sleeve 242 is fixedly connected to the drive rod 2. 2. In addition, the cleaning component 25 includes a second sealing sleeve 251. Several support blocks 252 are fixedly connected to the inner wall of the second sealing sleeve 251. These support blocks 252 are fixedly connected to the same connecting ring 253. Several scrapers 254 are fixedly connected below the connecting ring 253. The second sealing sleeve 251 is snapped into the mixing drum 141. The outer wall of the second sealing sleeve 251 is slidably connected to the protective shell 13. The lower part of the scrapers 254 overlaps with the lower part of the inner wall of the mixing drum 141. The medium-speed operation mode is relatively gentle and does not generate excessive heat and mechanical stress like high-speed mixing, thus effectively protecting the nutrients in the feed, such as vitamins and proteins. These nutrients are crucial for the growth and development of the pups. The gentle mixing method can retain their activity to the greatest extent, ensuring that the feed ingested by the pups has high nutritional value. In low-speed operation mode, operators can more easily control the direction and speed of the equipment's movement, accurately moving it to the feeding area. Simultaneously, upon reaching the feeding area, the discharge valve 16 is opened. Due to the lower operating speed, the discharge process is smoother and more orderly, enabling rapid and accurate discharge of feed, avoiding spillage and waste, and improving feed utilization.

[0027] Working principle: This embodiment provides a feed mixing and feeding device for raising ruminant cubs. When in use, the solid feed is first put into the feeding shell 15, so that the solid feed enters the mixing drum 141 along the feeding shell 15. Then, the driver 21 is switched to high-speed operation mode, medium-speed operation mode and low-speed operation mode in sequence. In high-speed operation mode, the crushing component 24 rotates at high speed under the drive rod 22. Since a second counterweight 245 is provided at one end of the telescopic crushing rod 241, the telescopic crushing rod 241 extends radially under the action of centrifugal force. The second counterweight 245 drives the telescopic crushing rod 241 to slide outward against the elastic force of the second spring 244, and pulls the stirring rod 243 to slide into the inside of the telescopic crushing rod 241 until the stirring rod 243 is attached to the outside of the drive rod 22. As the telescopic crushing rod 241 runs at high speed, the irregular design on the surface of the telescopic crushing rod 241 will efficiently crush the solid feed and complete the processing of the solid feed. When switching to medium-speed operation mode, the speed of drive 21 decreases, the centrifugal force weakens, the second spring 244 recovers its elasticity, pushes the telescopic crushing rod 241 to retract inward, and simultaneously drives the stirring rod 243 to slide out along the drive rod 22 axially. At this time, the stirring rod 243 will use its unique shape design to perform multi-directional shearing and laminar flow mixing of solid feed and liquid nutrient agents. In low-speed operation mode, the drive 21 further reduces speed, and the first spring 234 drives the slide rod 233 and pulley 236 to retract. At this time, the pulley 236 no longer squeezes the top of the mixing drum 141, and the mixing drum 141 moves down under its own weight, so that multiple limit plates 143 are engaged with the outside of the sliding sleeve 231. At this time, the drive rod 22 will drive the limit plate 143 and the mixing drum 141 to rotate through the sliding sleeve 231. The second sealing sleeve 251 and the scraper 254 are relatively fixed, thereby realizing the low-speed spiral conveying of the material in the mixing drum 141. After the device is moved to the designated position by the moving component 11, it is only necessary to open the discharge valve 16, and the mixed feed will be discharged along the discharge shell 172. When the device is in high-speed operation, the drive rod 22 synchronously drives the mounting sleeve 26 and the sliding sleeve 231 to rotate at high speed. This causes the first counterweight 235 to quickly pull the sliding rod 233 to extend under high-speed rotation. At the same time, the first counterweight 235 overcomes the elasticity of the first spring 234 under centrifugal force and slides radially outward along the sliding sleeve 231, causing the sliding rod 233 to extend synchronously. This pushes the pulley 236 to press against the conical inclined surface at the top of the mixing drum 141, thereby raising the height of the mixing drum 141. This causes the limiting plate 143 to disengage from the sliding sleeve 231, ensuring that the mixing drum 141 remains suspended and positioned during high-speed and medium-speed operation. During low-speed operation, the first spring 234 recovers its elasticity, the sliding rod 233 and the pulley 236 retract synchronously, and the mixing drum 141 moves downward under gravity. The limiting plate 143 re-engages into the outer groove of the sliding sleeve 231, achieving axial positioning and stable rotational conveying under low-speed conditions.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
