[0002] Yak feed mainly includes green feed, roughage, silage, energy feed and protein feed. Among them, green feed made by lactic acid bacteria fermentation has a good taste and is conducive to long-term preservation. Therefore, green feed is the main choice of yak feed. Fermented feed can significantly improve the nutritional value of feed, improve the microbial environment of animal intestines, enhance animal immunity, and reduce the occurrence of diseases. Fermented feed can make full use of various crop straws, forage and other waste resources to realize the recycling of resources. Therefore, the feed fermentation device improves the nutritional value and digestibility of feed through microbial fermentation, which is of great significance to the sustainable development of the breeding industry.

[0003] At present, in the process of yak breeding, in order to improve the absorption and utilization rate of nutrients in feed raw materials by yaks and meet the feed needs of yaks of different qualities, it is often necessary to ferment the feed raw materials to different degrees to promote yak absorption and ensure the healthy growth of yaks. Traditional fermentation equipment is not conducive to the fermentation treatment of a variety of feed raw materials, and increases the labor intensity of operators, thereby increasing the production cost of feed raw material fermentation operations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a yak feed fermentation device.

[0005] The technical solution adopted to solve the above technical problems is: a yak feed fermentation device, including a main bracket, a protective shell is fixedly connected to the upper and lower sides of the main bracket, a fermentation chamber is rotatably connected to the middle of the main bracket, side brackets are respectively fixedly connected to the two sides of the main bracket, and the two side brackets are rotatably fitted with the surface of the fermentation chamber, a power frame is provided on one side of the main bracket, a first motor and a second motor are fixedly connected to the upper and lower parts of the power frame, and a discharge port is provided at the bottom of the fermentation chamber, and the discharge port is fixedly connected to the main bracket.

[0006] Furthermore, the fermentation chamber is a cylindrical structure, and a power tube is rotatably connected to the center of the fermentation chamber. Both ends of the power tube are rotatably connected to the fermentation chamber, and the two through ends of the power tube are respectively rotatably connected to the middle of the main bracket. A plurality of partitions are fixedly connected to the cylindrical surface of the power tube, and the plurality of partitions are arranged in a cross array, and a plurality of partitions are slidably fitted with the inner wall of the fermentation chamber away from one end of the power tube. A plurality of spiral push rods are rotatably connected to the surface of the power tube, and the plurality of spiral push rods are located between the partitions, and the bottom end of the middle cylinder of the spiral push rod is rotatably connected to the power tube.

[0007] Through the above technical solution, the partitions arranged in a cross array divide the fermentation chamber into multiple partitions, which is convenient for the fermentation needs of feeds of different qualities. At the same time, when the power tube drives the partitions to rotate inside the fermentation chamber, the fermented material can be flipped and rolled to make it ferment evenly.

[0008] Furthermore, a transmission rod is slidably connected through the middle of the power tube, a second bevel gear is fixedly connected to the middle of the transmission rod, a plurality of first bevel gears are meshingly connected to the second bevel gear around the periphery, the first bevel gear is fixedly connected to the through end of the spiral push rod, a second gear is fixedly connected to one end of the transmission rod, one end of the transmission rod is fixedly connected to the power output end of the second motor, an inner ring gear is fixedly connected to one through end of the power tube, a gearbox is wrapped around the outer side of the inner ring gear, the gearbox is fixedly connected to the main bracket, one side of the second gear is meshingly connected to the first gear, and the other side of the first gear is meshingly connected to the inner ring gear.

[0009] Through the above technical solution, the second motor drives the transmission rod to rotate, and the rotation of the transmission rod drives the second bevel gear to rotate, thereby causing several first bevel gears around to rotate synchronously. These first bevel gears are connected to the through end of the spiral push rod, so when the transmission rod rotates, the spiral push rod will also rotate. Since the spiral push rod is located between the partitions, their rotation can achieve uniform flipping and mixing of the fermented material, which not only improves the fermentation efficiency, but also ensures the uniformity of the fermentation process, thereby improving the fermentation quality of the feed.

[0010] Furthermore, a plurality of sockets are provided in the middle of one side of the fermentation chamber, and the plurality of sockets are arranged in a circular array, a gear ring is fixedly connected to the corner ends of the cylindrical surface of the fermentation chamber, two sealed doors are rotatably connected to the cylindrical surface of the fermentation chamber, and the two sealed doors are symmetrically arranged, a slide rail is fixedly connected to the middle of the outer surface of the sealed door, a push rod is slidably connected to the inner side of the slide rail, an arc-shaped hydraulic push rod is fixedly connected to the middle of the push rod, the telescopic end of the arc-shaped hydraulic push rod is fixedly connected to the push rod, and the arc-shaped hydraulic push rod is fixedly connected to the surface of the fermentation chamber.

[0016] Furthermore, a conveyor belt is provided on one side of the main support, and the conveyor belt is a Z-shaped structure. One end of the conveyor belt is located at the center of the top of the main support, and a plurality of limit plates are provided on the surface of the conveyor belt. A plurality of auxiliary supports are fixedly connected to the bottom end of the conveyor belt, and the auxiliary supports are in contact with the ground.

[0017] Through the above technical solution, the raw materials are automatically fed into the device, and at the same time, a limit plate is arranged on the surface of the conveyor belt to effectively prevent the raw materials from spilling.

At the same time, since multiple nozzles at different angles are set, the fermentation liquid is ensured to be in uniform contact with the raw materials, thereby improving the fermentation efficiency.

[0020] The beneficial effects of the present invention are as follows: 1. The present invention divides the fermentation chamber into a plurality of partitions by partitions arranged in a cross array, so as to facilitate the simultaneous fermentation of feeds of different qualities.

A plurality of sprayers 5 are rotatably connected to the inner side of the stand 4, and one side of the plurality of sprayers 5 is connected to an infusion tube 6, and the end of the infusion tube 6 away from the sprayer 5 is connected to a water tank 12, and the water tank 12 is located inside the main bracket 1.

[0028] like Figures 4 to 5 As shown, a first support column 1101 is rotatably connected to the middle of the side bracket 11, and transmission disks 1107 are fixedly connected to both ends of the first support column 1101, and the transmission disk 1107 is meshed and transmission-connected with the gear ring 301, a first reel 1102 is fixedly connected to the middle of the first support column 1101, a first transmission belt 1103 is friction-connected to the inner side of the first reel 1102, and a first double-grooved reel 1105 is friction-connected to one end of the first transmission belt 1103 away from the first reel 1102, a second support column 1106 is fixedly connected to the middle of the first double-grooved reel 1105, and both ends of the second support column 1106 are rotatably connected to the side bracket 11, and the first double-grooved reel 1102 is friction-connected to the inner side of the first reel 1102. One side is frictionally connected with a second transmission belt 1104, and one end of the second transmission belt 1104 away from the first double-grooved reel 1105 is frictionally connected with a second double-grooved reel 1109, and a transmission shaft 1108 is fixedly connected to the middle of the second double-grooved reel 1109, and both ends of the transmission shaft 1108 are rotationally connected to the main bracket 1, and the through end of the transmission shaft 1108 is fixedly connected to the power output end of the first motor 14. The first motor 14 drives the transmission discs 1107 on both sides of the side bracket 11 to rotate in the same direction through the cooperation of various belts and reels. Since the transmission disc 1107 is meshed with the gear ring 301 outside the fermentation chamber 3, the fermentation chamber 3 is driven to rotate smoothly, thereby improving the safety of the device.

[0029] like Figure 6 to Figure 7 As shown, a plurality of jacks 317 are provided in the middle of one side of the fermentation chamber 3, and the plurality of jacks 317 are arranged in a circular array. A gear ring 301 is fixedly connected to the corner end of the cylindrical surface of the fermentation chamber 3, and two sealed doors 302 are rotatably connected to the cylindrical surface of the fermentation chamber 3, and the two sealed doors 302 are symmetrically arranged.

[0030] like Figure 6 to Figure 7 As shown, the through end of the power tube 305 away from the inner ring gear 309 is slidably connected with a push ring 313, and the push ring 313 is fixedly connected with a plurality of plug posts 312 close to the surface of the fermentation chamber 3. The plurality of plug posts 312 are arranged in a circular array, and the plurality of plug posts 312 are slidably engaged with the sockets 317. When the push ring 313 is pushed, the plug posts 312 on the surface of the push ring 313 are slidably engaged with the sockets 317 on the surface of the fermentation chamber 3, so that the power tube 305 rotates synchronously with the fermentation chamber 3. This structure facilitates switching of the positions of each partition chamber and the fermentation chamber 3, thereby realizing flexible application of various fermentation processes.

[0031] like Figure 6 to Figure 7 As shown, the fermentation chamber 3 is a cylindrical structure, and a power tube 305 is rotatably connected to the center of the fermentation chamber 3. Both ends of the power tube 305 are rotatably connected to the fermentation chamber 3, and the two through ends of the power tube 305 are respectively rotatably connected to the middle part of the main bracket 1. A plurality of partitions 306 are fixedly connected to the cylindrical surface of the power tube 305, and the plurality of partitions 306 are arranged in a cross array. The ends of the plurality of partitions 306 away from the power tube 305 are slidably fitted with the inner wall of the fermentation chamber 3. The partitions 306 arranged in a cross array divide the fermentation chamber 3 into a plurality of partitions to facilitate the fermentation needs of feeds of different qualities. A plurality of spiral push rods 308 are rotatably connected to the surface of the power tube 305, and the plurality of spiral push rods 308 are located between the partitions 306. The bottom end of the central cylinder of the spiral push rod 308 is rotatably connected to the power tube 305. At the same time, when the power tube 305 drives the partition 306 to rotate inside the fermentation chamber 3, the fermented material can be flipped and rolled to make it fermented evenly.

[0032] like Figures 7 and 8 As shown, a transmission rod 307 is slidably connected to the middle of the power tube 305, a second bevel gear 315 is fixedly connected to the middle of the transmission rod 307, and a plurality of first bevel gears 314 are meshed and transmission-connected around the second bevel gear 315. The first bevel gear 314 is fixedly connected to the through end of the screw push rod 308, and a second gear 311 is fixedly connected to one end of the transmission rod 307. One end of the transmission rod 307 is fixedly connected to the power output end of the second motor 15, and an inner ring gear 309 is fixedly connected to one through end of the power tube 305. The outer ring gear 309 of the inner ring gear 309 is fixedly connected to the inner ring gear 309. The side is wrapped with a gearbox 13, which is fixedly connected to the main bracket 1. One side of the second gear 311 is meshed and connected to the first gear 310, and the other side of the first gear 310 is meshed and connected to the inner ring gear 309. Therefore, when the transmission rod 307 rotates, the spiral push rod 308 will also rotate accordingly. Since the spiral push rod 308 is located between the partitions 306, their rotation can achieve uniform turning and mixing of the fermented material, which not only improves the fermentation efficiency, but also ensures the uniformity of the fermentation process, thereby improving the fermentation quality of the feed.

[0033] The working principle of this embodiment is as follows: First, the user can prepare the required fermentation liquid in the water tank 12, and then place the feed raw materials on the conveyor belt 7. Since one end of the conveyor belt 7 is located at the top center of the main bracket 1, the raw materials are automatically sent to the top opening of the fermentation chamber 3. At the same time, a limit plate 8 is set on the surface of the conveyor belt 7. The sprayer 5 draws the liquid inside the water tank 12 through the infusion tube 6 and sprays it. At the same time, since a plurality of nozzles at different angles are set, it is ensured that the fermentation liquid and the raw materials are in uniform contact during the process of falling into the fermentation chamber 3. When the raw materials fall into the partition separated by the partition 306, the second motor 15 drives the transmission rod 307 to rotate, and the rotation of the transmission rod 307 drives the second bevel gear 315 to rotate, thereby making the several first bevel gears 314 around it rotate synchronously. These first bevel gears 314 are connected to the through ends of the spiral push rods 308, so when the transmission rod 307 rotates, the spiral push rods 308 will also rotate accordingly. Since the spiral push rods 308 are located between the partitions 306, their rotation can achieve uniform flipping and mixing of the fermented material, which not only improves the fermentation efficiency, but also ensures the uniformity of the fermentation process, thereby improving the fermentation quality of the feed. At the same time, due to the internal structure of the gearbox 13, the transmission rod 307 can drive the rotating power tube 305 to achieve the switching of the partitions, which is convenient for different fermentation needs. Subsequently, the arc-shaped hydraulic push rod 304 drives the push rod to move along the slide rail 303, thereby pushing the sealing door 302 to close, ensuring that the fermentation chamber 3 is stirred. The sealing of the material is ensured to prevent the outside air from entering. The first motor 14 drives the transmission disks 1107 on both sides of the side bracket 11 to rotate in the same direction through the cooperation of various belts and reels. Since the transmission disk 1107 is engaged with the gear ring 301 outside the fermentation chamber 3, the fermentation chamber 3 is driven to rotate smoothly. Their rotation can achieve uniform turning and mixing of the fermented material, which not only improves the fermentation efficiency, but also ensures the uniformity of the fermentation process, thereby improving the fermentation quality of the feed. When the fermentation is completed, the sealed door 302 of the fermentation chamber 3 is aligned with the discharge port 16 at the bottom, and the sealed door 302 is opened. Under the continuous rotation of the power tube 305, all the feed inside the fermentation chamber 3 is taken out, and the fermentation is completed.
