Description

Technical Field

[0001] This invention belongs to the field of drying technology, and specifically relates to a forage drying device for cattle feeding. Background Technology

[0002] Drying equipment is a type of mechanical equipment used to remove moisture (such as water or other volatile components) from materials. It is widely used in industrial production, laboratory research, and food and pharmaceutical processing. The core function of forage drying is to control moisture content and inhibit biological activity, thereby achieving long-term preservation and nutritional maintenance of forage and ensuring a stable supply for livestock throughout the year. However, in existing forage drying devices, hot air simply passes through the forage and removes moisture without evenly distributing it throughout the forage. This results in uneven drying, with some forage completely dried while others remain moist. In such cases, to ensure all forage is dried, further drying is required, leading to a further decrease in moisture content in the already dried forage, resulting in nutrient loss and affecting the quality of the dried forage. Therefore, designing a forage drying device for cattle is a problem that needs to be solved. Summary of the Invention

[0015] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 9 The above-described feed drying device for cattle includes a feed hopper 1 and a motor 2. The output shaft of the motor 2 is fixedly connected to a drive wheel 3. A driven wheel 4 is meshed with the outer wall of the drive wheel 3. A rotating shaft 5 is fixedly connected to the top of the driven wheel 4. The rotating shaft 5 is rotatably connected inside the feed hopper 1. A hot air pipe 6 and a stirring ring 7 are fixedly installed on the outer wall of the rotating shaft 5. The hot air pipe 6 and the stirring ring 7 are fixedly connected together. The drying component is used to dry the forage evenly. The drying component is connected to the feed hopper 1, the rotating shaft 5 and the hot air pipe 6. The filter assembly is used to filter the hot air and is connected to the material tank 1 and the drying assembly.

[0017] The drying assembly includes two connecting rings 8 slidably connected inside a rotating shaft 5. Each connecting ring 8 has a pressure spring 9 and a steel wire rope 10 fixedly mounted at its opposite ends. The ends of the two pressure springs 9 away from their corresponding connecting rings 8 are fixedly mounted inside the rotating shaft 5. The ends of the two steel wire ropes 10 away from their corresponding connecting rings 8 pass through the pressure springs 9 and are inserted into the hot air duct 6. Multiple seals 11 and ball bearings 12 are fixedly mounted on the outer wall of the steel wire ropes 10. Both the seals 11 and ball bearings 12 are inserted into the hot air duct 6. A limit bolt 13 is rotatably connected to the end of the steel wire rope 10 away from its corresponding connecting ring 8. The limit bolt 13 is threaded into the hot air duct 6. The outer wall of the shaft 6 is provided with hot air holes 14 corresponding to the number of seals 11. The seals 11 are located on one side of the hot air holes 14. The outer wall of the shaft 5 is rotatably connected to a collar 15. The shaft 5 is provided with air holes for hot air flow. The outer wall of the collar 15 is fixedly connected to a connecting pipe 16. The end of the connecting pipe 16 away from the collar 15 is fixedly connected to the housing of the fan 17. The outer wall of the housing of the fan 17 is fixedly connected to an air inlet pipe 18. The outer wall of the air inlet pipe 18 is fixedly installed with a heater 19 and a dehumidifier 20 in sequence. The fan 17, heater 19 and dehumidifier 20 are all fixedly installed inside the material barrel 1. The end of the air inlet pipe 18 away from the fan 17 passes through the material barrel 1 and is fixedly connected to a circulation pipe 21. The circulation pipe 21 is fixedly installed on the outer wall of the material barrel 1. The drying component is used to divert hot air so that it can be evenly diffused into the interior of the hay and dry the hay evenly. Among them, the sealing element 11 is a hollow structure, which allows hot air to pass through the sealing element 11 along the hot air pipe 6 until the hot air is blocked by the baffle ball 12. The hot air pushes the baffle ball 12 to slide along the inside of the hot air pipe 6, and pulls multiple sealing elements 11 through the steel wire rope 10 to stop sealing the corresponding hot air holes 14, so that the hot air can be discharged to dry the hay evenly. Specifically, when it is necessary to dry the hay inside the feed hopper 1, the motor 2 and the fan 17 are first started. The motor 2 drives the driven wheel 4 to rotate via the drive wheel 3, which in turn drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the hot air pipe 6 and the stirring ring 7 to rotate, allowing the stirring ring 7 to stir and break up the hay inside the feed hopper 1. Meanwhile, the fan 17 draws air from inside the feed hopper 1 through the air inlet pipe 18 and the circulation pipe 21. During this process, the filter assembly filters the air entering the circulation pipe 21 to prevent dust from entering, the dehumidifier 20 removes moisture from the air, and the heater 19 heats the air after the moisture has been removed. Then, the fan 17 turns the heated air into hot air and discharges it into the jacket through the connecting pipe 16. Inside the ring 15, the ring 15 is discharged into the hot air pipe 6 through the air hole opened on the rotating shaft 5. After the hot air is discharged into the hot air pipe 6, the hot air will flow along the inside of the hot air pipe 6 and blow the baffle ball 12 towards the direction of the limit bolt 13, so that the baffle ball 12 pulls the steel wire rope 10 to move together. During this process, the steel wire rope 10 will pull the seal 11 to stop sealing the hot air hole 14, so that the hot air inside the hot air pipe 6 can be evenly discharged into different positions inside the material bucket 1 through multiple hot air holes 14, so that the hot air can be evenly diffused and pass through the straw inside the material bucket 1 to dry the straw evenly and avoid uneven drying. During this process, the steel wire rope 10 will pull the connecting ring 8 to slide along the inside of the rotating shaft 5, so that the connecting ring 8 squeezes the pressure spring 9 to contract and store force. Furthermore, after the hot air is evenly diffused through the hot air holes 14 on the hot air pipe 6 and passes through the hay to dry it evenly, the hot air will carry water vapor and dust generated during the drying process through the filter assembly, which will filter the dust in the hot air and allow the hot air and water vapor to be discharged into the interior of the circulation pipe 21. The circulation pipe 21 will then pass through the dehumidifier 20 to remove the water vapor again. After being heated by the heater 19, it will be discharged back into the material bucket 1 by the fan 17, so that the hot air inside the drying device is circulated and the heat in the hot air is recycled, thereby reducing the energy consumed by the drying device. At the same time, the internal circulation of hot air can prevent the hot air and dust from being discharged to the outside, which would affect the surrounding environment and the health of the workers. Furthermore, once the straw inside the hopper 1 is dried and the blower 17 stops working, the hot air circulation stops, causing the baffle ball 12 to lose the push of the hot air. This allows the pressure spring 9 to push the connecting ring 8 to reset, which in turn pulls the corresponding steel wire rope 10 to reset. The steel wire rope 10 then drives the seal 11 and the baffle ball 12 to reset. The reset of the seal 11 seals the hot air hole 14, preventing the straw and dust inside the hopper 1 from entering the interior of the hot air pipe 6, clogging the hot air pipe 6 and the hot air hole 14, and affecting the normal operation of the drying components.

[0018] The filter assembly includes a filter housing 22 fixedly installed at the end of the circulation pipe 21 away from the air inlet pipe 18. The filter housing 22 is fixedly installed on the top inner wall of the material tank 1. Two elastic plates 23 are fixedly installed inside the filter housing 22. A connecting rod 24 is inserted between the two elastic plates 23. Slide plates 25 are fixedly installed at both ends of the connecting rod 24. The two slide plates 25 are slidably connected inside the filter housing 22. A first filter screen 26 is fixedly installed inside each of the two slide plates 25. Two fixing plates 27 are arranged between the two slide plates 25 and are fixedly installed inside the filter housing 22. A second filter screen 28 is fixedly installed inside each of the two fixing plates 27. The first filter screen 26 and the second filter screen 28 intersect. Incorrect configuration: A pressure rod 29 is fixedly connected to the outer wall of the connecting rod 24. The pressure rod 29 abuts against one side of the two elastic plates 23. A sealing plate 30 is fixedly connected to the end of the pressure rod 29 away from the connecting rod 24. The sealing plate 30 is slidably connected to the inside of the filter shell 22. A collection component 31 is fixedly connected to the side of the sealing plate 30 away from the pressure rod 29. The collection component 31 is slidably connected to one side of the filter shell 22. Two collection grooves 32 are opened on the side of the filter shell 22 that is slidably connected to the collection component 31. The collection component 31 has a groove that matches the two collection grooves 32. A dust exhaust hose 33 is fixedly connected to the outer wall of the collection component 31. The end of the dust exhaust hose 33 away from the collection component 31 passes through the material bucket 1 and is fixedly connected to the collection bucket 34. The filter assembly is used to filter and collect the dust carried by the hot air, preventing the dust from entering the circulation with the hot air and clogging the components in the drying assembly, reducing the amount of dust in the straw inside the hopper 1, and reducing the dust when the straw is discharged from the hopper 1. Specifically, when hot air carrying dust passes through the first filter screen 26 and the second filter screen 28 inside the filter housing 22, the first filter screen 26 and the second filter screen 28 will filter the dust in the hot air twice, improving the dust filtration effect. As the first filter screen 26 and the second filter screen 28 are gradually clogged by dust, the hot air resistance on the slide plate 25 will gradually increase, causing the slide plate 25 to move along the inside of the filter housing 22 towards the fixed plate 27. During this process, the slide plate 25 will drive the pressure rod 29 and another slide plate 25 to move synchronously through the connecting rod 24, causing the pressure rod 29 to squeeze the two elastic plates 23 to open to both sides, allowing the pressure rod 29 to pass through the elastic plates 23. 3. After the pressure rod 29 passes between the two elastic plates 23, the corresponding slide plate 25 of the first filter screen 26 blocked by dust will abut against the adjacent fixed plate 27, so that the slide plate 25 and the fixed plate 27 cooperate to seal, preventing hot air from passing through in this direction. At the same time, the slide plate 25 on the other side of the filter housing 22 is pushed away from the adjacent fixed plate 27 by the connecting rod 24, allowing hot air to pass through. The first filter screen 26 and the second filter screen 28 on the slide plate 25 and the fixed plate 27 on the other side of the filter housing 22 filter the dust in the hot air, so that the two first filters 26 and the two second filters 28 in the filter assembly alternately remove the dust in the hot air. It should be noted that by rounding the outer wall of the second filter 28, the pressure required for the second filter 28 to squeeze the two elastic pieces 23 to open to both sides is reduced. When the second filter 28 is about to pass through the elastic pieces 23 that are opening to both sides, the two open elastic pieces 23 can reset and squeeze the rounded back of the second filter 28, so that the second filter 28 moves quickly under the pressure of the elastic pieces 23. This allows the connecting rod 24 to drive the slide plate 25 and the first filter 26 blocked by dust to collide with the nearby fixed plate 27, causing the first filter 26 on the slide plate 25 and the second filter 28 on the fixed plate 27 to vibrate, removing the dust accumulated on the first filter 26 and the fixed plate 27. Furthermore, as the second filter screen 28 moves along the connecting rod 24, the second filter screen 28, through the pressure rod 29, causes the sealing plate 30 to move along the outer wall of the filter housing 22. This allows the slot on the collecting element 31 to be offset from one of the collecting grooves 32, and the other slot on the collecting element 31 to coincide with the other collecting groove 32. This allows the dust removed by vibration from the clogged first filter screen 26 and second filter screen 28 to be discharged into the interior of the collecting element 31 through the collecting groove 32. The dust can then be discharged into the dust discharge hose 33 along the inclined surface inside the collecting element 31. Subsequently, the dust is discharged into the dust collection hose 33. The interior of the collecting bin 34 is designed to remove dust from the hot air, dust adhering to the first filter screen 26 and the second filter screen 28, and to collect the removed dust. This prevents dust from being discharged back into the material bin 1, which would cause excessive dust to be generated when the hay is discharged from the material bin 1. It also prevents the hot air from carrying the dust discharged back into the material bin 1 and clogging the first filter screen 26 and the second filter screen 28 again. It should be noted that when the collecting component 31 moves and drives the dust discharge hose 33 to move, the baffle on the dust discharge hose 33 will move together to seal the groove opened in the material bin 1 for the movement of the dust discharge hose 33, thus preventing hot air from being discharged.

[0019] A sealing plate 35 is slidably connected to the outer wall of the material bucket 1. A first electric push rod 36 is hinged to the outer wall of the sealing plate 35. The end of the first electric push rod 36 away from the sealing plate 35 is fixedly installed on the outer wall of the material bucket 1. A second electric push rod 37 is rotatably connected to the top of the material bucket 1. A telescopic rod 38 is hinged to one end of the second electric push rod 37. A cover plate 39 is fixedly connected to the end of the telescopic rod 38 away from the second electric push rod 37. The cover plate 39 is rotatably connected to the top of the material bucket 1. A guide port 40 is fixedly connected to the top of the cover plate 39. The bottom inner contour of the guide port 40 is adapted to the top feed port of the material bucket 1. A staircase 41 is fixedly installed on one side of the material bucket 1. The staircase 41 is located on the top of the motor 2. Among them, the sealing plate 35 and the first electric push rod 36 are used to control the opening and closing of the discharge port of the material bucket 1; Specifically, when it is necessary to discharge the dried hay inside the feed hopper 1, the first electric push rod 36 can be controlled to retract, so that the first electric push rod 36 pulls the sealing plate 35 to slide along the outer wall of the feed hopper 1 and open the seal on the discharge port of the feed hopper 1, so that the dried hay inside the feed hopper 1 can be discharged from the feed hopper 1. Among them, the second electric push rod 37 and the telescopic rod 38 are used to control the opening and closing of the feed inlet at the top of the material bucket 1; The central axis of the connection between the telescopic rod 38 and the cover plate 39 and the rotation connection between the cover plate 39 and the top of the material bucket 1 are the same, so that when the second electric push rod 37 drives the cover plate 39 to rotate through the telescopic rod 38, the cover plate 39 can rotate ninety degrees in the rotation area at the top of the material bucket 1. Specifically, when it is necessary to control the closure of the feed inlet at the top of the material hopper 1, the second electric push rod 37 can be retracted. This causes the second electric push rod 37 to pull the telescopic rod 38 to rotate 90 degrees around the pivot point where the cover plate 39 is connected to the top of the material hopper 1. This, in turn, causes the telescopic rod 38 to rotate the cover plate 39 90 degrees until the cover plate 39 is blocked by the top of the material hopper 1. During this process, the cover plate 39 will cause the guide port 40 to be misaligned with the feed inlet at the top of the material hopper 1, and the cover plate 39 will cover the top of the material hopper 1 for feeding. Above the opening, the cover plate 39 seals the top feed inlet of the material bucket 1 to prevent hot air and dust from leaking through the feed inlet. When it is necessary to reopen the top feed inlet of the material bucket 1, the second electric push rod 37 can be extended to drive the telescopic rod 38 to rotate 90 degrees and reset, so that the telescopic rod 38 drives the cover plate 39 to reset, and the guide port 40 on the cover plate 39 coincides with the top feed inlet of the material bucket 1. At this time, the grass can be put into the inside of the material bucket 1 through the feed inlet through the guide port 40.

[0020] Working principle: When the drying equipment is used to dry the material bucket 1, firstly, the second electric push rod 37 controls the guide port 40 to coincide with the top feed port of the material bucket 1, so that the straw can be guided by the guide port 40 and discharged into the inside of the material bucket 1 through the feed port. Then, the second electric push rod 37 controls the cover plate 39 to seal the top feed port of the material bucket 1. Then, the motor 2 and the fan 17 are controlled to work, so that the motor 2 drives the stirring ring 7 to rotate and stir and disperse the straw inside the material bucket 1. The fan 17 distributes hot air evenly through the hot air holes 14 on the hot air pipe 6. The hot air diffuses into the hay inside the feed hopper 1, and dries the mixed and dispersed hay evenly. Then, the hot air carries the dust and water vapor through the filter assembly, which filters the dust in the hot air and collects it in the collection bucket 34. The hot air and water vapor can continue to circulate, and the water vapor in the hot air is removed during the circulation process. The hot air is then reheated until the hay inside the feed hopper 1 is completely dried. At this point, the first electric push rod 36 can be controlled to pull the sealing plate 35 to open the discharge port of the feed hopper 1, allowing the hay inside the feed hopper 1 to be discharged.
