[0002] In livestock farming, hay is essential as feed for cattle and sheep. Hay is a major food for animals, and it is relatively fluffy, so storing it requires a large amount of storage space. Therefore, it is necessary to crush the hay before storing it, and after crushing, it is convenient to feed the animals.

[0003] When the existing hay cutting and crushing device is in use, the hay is cut multiple times by the cutting blades to make it into shorter hay fragments. Since the distance between the cutting blades on the existing device is constant, when the hay just enters the inside of the cutting box, the cutting blades cut it into the smallest segments, resulting in the cutting blades bearing a large cutting resistance at the beginning, causing the machine to bear a large cutting load, easily damaging the machine, and affecting the normal service life of the machine.

Detailed implementation manners

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0018] Because when the hay bundle starts to be cut and crushed, the cutter needs to bear a large cutting load. To solve this problem, the present application discloses a hay feed crushing and drying device, as Figures 1-3 shown, including: a base 1, a carrier for installing device components, a crushing box 2, the crushing box 2 is arranged on the top of the base 1 and fixedly installed thereon, and a cutting and crushing assembly for cutting and crushing hay.

[0019] The cutting and crushing assembly is arranged inside the crushing box 2. The cutting and crushing assembly includes: a rotating shaft 10 rotatably installed between the inner walls on opposite sides of the crushing box 2. Two turntables 15 are symmetrically and fixedly installed on the outer surface of the rotating shaft 10. A plurality of first hollow shafts 16 are rotatably installed at equal intervals in the circumferential direction between the two turntables 15. A plurality of second hollow shafts 17 are also rotatably installed at equal intervals in the circumferential direction between the two turntables 15. The plurality of first hollow shafts 16 and the plurality of second hollow shafts 17 are alternately arranged with each other. A plurality of groups of first cutter plates 18 are slidably installed at equal intervals in pairs on the outer surface of the first hollow shaft 16. A plurality of second cutter plates 19 are fixedly installed at equal intervals on the outer surface of the second hollow shaft 17. The second cutter plates 19 are arranged between a group of two first cutter plates 18. A plurality of telescopic grooves 1901 are symmetrically formed on the outer surfaces of the opposite sides at both ends of the second cutter plate 19. A diamond-shaped cutter 28 is slidably installed on the inner wall of each of the plurality of telescopic grooves 1901. The diamond-shaped cutter 28 is used for cutting dry hay.

[0020] For the convenience of understanding the directions mentioned in the description, as Figure 1 shown, in the device, the side where the first pulley 4 is located is taken as the front view surface. Since the rotating shaft 10 is arranged inside the crushing box 2, in the front view surface, with the center of the rotating shaft 10 as the center, the horizontal plane where the center of the rotating shaft 10 is located is upward as the upper part of the crushing box 2, and vice versa; the vertical plane where the center of the rotating shaft 10 is located is to the left as the left side of the crushing box 2, and vice versa. The feeding port of the crushing box 2 is arranged on the left side of the crushing box 2.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the rotating shaft 10 drives the two turntables 15 to rotate counterclockwise. The two turntables 15 drive the first hollow shafts 16 and the second hollow shafts 17 to rotate counterclockwise with the rotating shaft 10 as the rotation center. As Figure 4 shown, the first hollow shafts 16 and the second hollow shafts 17 rotate counterclockwise by the cooperation of the first gears 20 and the ring outer gears 21. The second cutter plates 19 move relatively between a group of two first cutter plates 18, that is, the two ends of the second cutter plate 19 move relatively with the adjacent ends of a group of two first cutter plates 18, thereby generating a shearing motion. Through this setting, the dry hay can be cut and shredded.

[0022] In this embodiment, the adjusting component is used to adjust the distance between a set of two first cutter plates 18. The adjusting component is arranged inside the first hollow shaft 16. The adjusting component includes: a fixing plate 23 fixedly installed between the inner walls of the first hollow shaft 16. On the outer surface of the fixing plate 23 on the side opposite to the rotating shaft 10, two dovetail grooves 2301 are symmetrically formed. Slide bars 24 are slidably installed on the inner walls of the two dovetail grooves 2301. On the inner walls of a set of two first cutter plates 18, limit sliders 1801 are fixedly installed. On the outer surface of the first hollow shaft 16, multiple groups of limit sliding grooves 1601 are equidistantly formed in pairs. One end of a set of two limit sliders 1801 is respectively slidably installed on the inner walls of a set of two limit sliding grooves 1601. The other ends of a set of two limit sliders 1801 penetrate through the inner wall of the first hollow shaft 16 and are respectively fixedly installed on the outer surfaces of two slide bars 24. On the upper surface of the fixing plate 23 near one end of the first belt pulley 4, a counterbore 2302 is formed. A first sliding column 25 is slidably installed on the inner wall of the counterbore 2302. The end of the first sliding column 25 away from the first belt pulley 4 is fixedly installed with one end of one of the slide bars 24. Inside the counterbore 2302, a second spring 35 is arranged. One end of the second spring 35 is fixedly connected to the end of the first sliding column 25 away from the first belt pulley 4. The other end of the second spring 35 is fixedly connected to the inner wall of the counterbore 2302 away from the first belt pulley 4. A second gear 26 is rotatably installed on the upper surface of the fixing plate 23 near the middle position. On the outer surfaces of the adjacent ends of the two slide bars 24, racks 27 are fixedly installed. The racks 27 are meshed with the second gear 26. A driving ring 22 is fixedly installed on the inner wall of the crushing box 2 near the annular external gear 21. The end face of the driving ring 22 is provided with an inclined surface. The other end of the first sliding column 25 is provided with a first spherical surface. The first spherical surface at the other end of the first sliding column 25 abuts against the inclined surface of the driving ring 22.

[0023] As shown by the arrow in Figure 4 , when the two turntables 15 drive the first hollow shaft 16 to rotate counterclockwise around the rotating shaft 10, the first spherical surface of the first sliding column 25 is driven by the first hollow shaft 16 to slide along the inclined surface of the driving ring 22. As shown in Figure 15 , because the end face of the driving ring 22 is inclined, and the thicker area of the inclined surface is arranged in the lower left area of the crushing box 2, that is, as shown in Figure 3 and Figure 4 , when the first spherical surface of the first sliding column 25 rotates to the lower left area of the crushing box 2, the first spherical surface of the first sliding column 25 is squeezed by the inclined surface of the driving ring 22, so that the first sliding column 25 moves in a direction relatively away from the driving ring 22. As shown in Figure 6 , Figure 7 and Figure 8As shown, the first sliding column 25 drives one of the first cutting plates 18 away from the driving ring 22 through one of the sliding bars 24. One of the sliding bars 24 drives the other sliding bar 24 to move closer to the driving ring 22 through the cooperation of two racks 27 and the second gear 26. The other sliding bar 24 drives the other first cutting plate 18 to move closer to the driving ring 22. Therefore, when a set of two first cutting plates 18 move to the area near the lower left of the crushing box 2, they will move closer to each other, reducing the distance between them. As a result, the distance between the second cutting plate 19 and the set of two first cutting plates 18 decreases. Through this device, the distance between the second cutting plate 19 and the set of two first cutting plates 18 can be reduced when they move to the area near the lower left of the crushing box 2, so that the hay can be cut and shredded smaller.

[0024] On the contrary, when the turntable 15 rotates to drive the first spherical surface of the first sliding column 25 to move to the upper left area of the crushing box 2, since the first spherical surface moves to the thinner area segment of the inclined surface of the driving ring 22, the first sliding column 25 will move relatively closer to the driving ring 22. At this time, the first sliding column 25 drives one of the sliding bars 24 to move relatively closer to the driving ring 22. One of the sliding bars 24 drives the first cutting plates 18 on the outer surfaces of the two sliding bars 24 to move away from each other through the cooperation of two racks 27 and the second gear 26, so that the distance between the two first cutting plates 18 increases. Furthermore, the distance between the second cutting plate 19 and the adjacent two first cutting plates 18 increases. When the hay feed is shredded, it enters the inside of the crushing box 2 through the feeding port area in the upper left of the crushing box 2. At this time, because the distance between the second cutting plate 19 and the adjacent two first cutting plates 18 in the feeding port area in the upper left of the crushing box 2 is large, the larger cutting distance makes the initial cutting process not too intense. At the same time, the larger distance helps to process relatively rough or larger hay bales, preventing the hay bales from accumulating too much and causing jamming or blockage, avoiding excessive friction between the second cutting plate 19 and the adjacent two first cutting plates 18 and the hay, reducing the load of the machine, and prolonging the service life of the equipment.

[0025] In this embodiment, the control component is used to control the diamond cutter 28 to extend and retract from the outer surface of the second cutter plate 19. The control component is arranged inside the second hollow shaft 17. The control component includes a cross plate 30 slidably mounted inside the second hollow shaft 17. Two sliding grooves 1702 are symmetrically formed on the inner wall of the second hollow shaft 17. Two sides of the cross plate 30 are respectively slidably mounted on the inner walls of the two sliding grooves 1702. A plurality of second inclined grooves 3001 are symmetrically formed on the upper surfaces of the other two sides of the cross plate 30. Two mounting grooves 1902 are symmetrically formed on the outer surfaces of the two ends of the second cutter plate 19. Driving plates 29 are arranged inside the two mounting grooves 1902. One adjacent end of the two driving plates 29 penetrates through the inner wall of the second cutter plate 19 and is slidably mounted thereon. The outer surface of the second hollow shaft 17 is penetrated by multiple groups of jacks 1701 at equal intervals in groups of two. One adjacent end of the two driving plates 29 respectively penetrates through a group of two jacks 1701 and is slidably mounted on their inner walls. Second guide posts 2901 are fixedly mounted on the inner walls of one adjacent ends of the two driving plates 29. The second guide posts 2901 are slidably mounted on the inner walls of the second inclined grooves 3001. Openings 2903 are formed inside the two driving plates 29. The diamond cutter 28 is arranged inside the openings 2903 and is slidably mounted on the inner walls of the openings 2903. A plurality of first inclined grooves 2902 are penetrated through the outer surfaces of the two driving plates 29 at equal intervals. A first guide post 2801 is fixedly mounted at the bottom end of the diamond cutter 28. The first guide post 2801 is slidably mounted on the inner walls of the first inclined grooves 2902. A second sliding column 32 is fixedly mounted at one end of the cross plate 30 close to the driving ring 22. A mounting plate 31 is fixedly mounted on the inner wall of one end of the second hollow shaft 17. One end of the second sliding column 32 penetrates through the outer surface of the mounting plate 31 and is slidably mounted thereon. A limit ring 3201 is fixedly mounted on the outer surface of one end of the second sliding column 32 close to the driving ring 22. A first spring 33 is sleeved on the outer surface of the second sliding column 32. One end of the first spring 33 is fixedly connected to the outer surface of the limit ring 3201. The other end of the first spring 33 is fixedly connected to the outer surface of the mounting plate 31. A second spherical surface is formed at the other end of the second sliding column 32. The second spherical surface at the other end of the second sliding column 32 abuts against the inclined surface of the driving ring 22.

[0026] As Figure 4 , Figure 6 , Figure 10 and Figure 11 shown, when the two turntables 15 drive the second hollow shaft 17 to rotate counterclockwise around the rotating shaft 10, the second hollow shaft 17 drives the second spherical surface of the second sliding column 32 to slide along the inclined surface of the driving ring 22. When the second spherical surface of the second sliding column 32 moves to the area below the left side of the crushing box 2, the second sliding column 32 is squeezed by the inclined surface of the driving ring 22, driving the second sliding column 32 to move in a direction away from the driving ring 22, so that the second sliding column 32 drives the cross plate 30 to move in a direction away from the driving ring 22. The cross plate 30 drives the second inclined grooves 3001 and the second guide posts 2901 to cooperate, asFigure 12 As shown, it drives the two driving plates 29 to move away from each other. The two driving plates 29 drive the diamond cutter 28 to extend out of the telescopic groove 1901 through the cooperation of the first inclined groove 2902 and the first guide post 2801, as Figure 12 shown, Figure 13 and Figure 14 shown. The cross-section of the diamond cutter 28 is a rhombus with two cutting edges.

[0027] When the diamond cutter 28 extends out of the telescopic groove 1901, it can cut the hay bundle entering between the first cutter plate 18 and the second cutter plate 19 in a group of two. At the same time, the diamond cutter 28 extends out at the position of the feed inlet at the lower left of the crushing box 2, so that the surface of the second cutter plate 19 moving towards the inside of the crushing box 2 protrudes the diamond cutter 28. The protruding diamond cutter 28 can conveniently drive the hay into the inside of the crushing box 2, facilitating subsequent cutting.

[0028] In the upper right region of the crushing box 2, the second sliding column 32 moves to the thinner position of the driving ring 22, so the second sliding column 32 is not squeezed, causing the diamond cutter 28 to retract into the inside of the second cutter plate 19. Since the diamond cutter 28 and the telescopic groove 1901 are matched, there will not be too large a gap between the two, thus preventing hay debris from entering the inside of the telescopic groove 1901. At the same time, after the diamond cutter 28 retracts into the telescopic groove 1901, the end face of its top is flush with the outer surface of the second cutter plate 19, making the surface of the second cutter plate 19 smooth and not protruding, so that when the hay is agitated and driven to the upper right of the crushing box 2, it will not be caught by the diamond cutter 28. Thus, the hot air blown out by the hot air pipe 34 can easily disperse the hay, facilitating the heat dissipation of the hay. During agitation, the smaller hay debris can be screened out from the mesh holes of the sieve plate 13.

[0029] In this embodiment, a driving motor 3 is fixedly installed on the upper surface of the base 1 relative to the feeding end of the crushing box 2. The output end of the driving motor 3 is fixedly installed with a first belt pulley 4. One end of the rotating shaft 10 penetrates through the outer surface of the crushing box 2 and is fixedly installed with a second belt pulley 5. A first belt 6 is wound around the outer surfaces of the first belt pulley 4 and the second belt pulley 5. One end of each of the plurality of first hollow shafts 16 and the plurality of second hollow shafts 17 close to the first belt pulley 4 penetrates through the outer surface of one of the turntables 15 and is fixedly installed with a first gear 20. An annular external gear 21 is fixedly installed on the inner wall of the crushing box 2 close to the first gear 20. The first gear 20 meshes with the annular external gear 21. Two protective covers 14 are symmetrically and fixedly installed on the inner walls of the two opposite sides of the crushing box 2. The two turntables 15 are arranged inside the two protective covers 14. The first gear 20 and the annular external gear 21 are protected by the protective covers 14 to prevent them from being exposed to the external environment.

[0030] In this embodiment, a conveyor tube 11 is fixedly installed at the bottom of the crushing box 2. A screw shaft 12 is rotatably installed on the inner wall of the conveyor tube 11 near one end of the second pulley 5. One end of the screw shaft 12 penetrates through the outer surface of the conveyor tube 11 and is fixedly installed with a third pulley 7. One end of the rotating shaft 10 is also fixedly installed with a fourth pulley 8. A second belt 9 is wound around the outer surfaces of the fourth pulley 8 and the third pulley 7. The inside of the conveyor tube 11 is communicated with the inside of the crushing box 2. A sieve plate 13 is fixedly installed on the inner wall of the crushing box 2 near the bottom end. The sieve plate 13 is arranged between the conveyor tube 11 and the crushing box 2.

[0031] When the hay is cut and shredded inside the crushing box 2, it will be stirred up and cut repeatedly with the movement of the first cutting plate 18 and the second cutting plate 19. The stirred-up hay is easier to dry. At the same time, the cut and shredded hay scraps will fall into the inside of the conveyor tube 11 through the mesh holes of the sieve plate 13, as Figure 1 and Figure 2 shown. The rotating shaft 10 drives the fourth pulley 8 to rotate. The fourth pulley 8 drives the third pulley 7 to rotate through the second belt 9. The third pulley 7 drives the screw shaft 12 to rotate. The hay scraps that fall into the inside of the conveyor tube 11 are conveyed to the inside of the collection box at the discharge end of the conveyor tube 11 through the screw shaft 12, which is convenient for subsequent processing.

[0032] In this embodiment, sleeves are provided at opposite ends of a group of two first cutting plates 18. When the first cutting plates 18 slide, the sleeves can prevent the limit sliding grooves 1601 from being exposed to the external environment, avoiding the crushed hay from entering the inside of the first hollow shaft 16.

[0033] The working principle of the present invention is that during use, the operator conveys the hay material to the feed port of the crushing box 2 manually or through a feeding belt, and then drives the first pulley 4 to rotate through the driving motor 3. The first pulley 4 drives the second pulley 5 to rotate through the first belt 6. The second pulley 5 drives the rotating shaft 10 to rotate, as Figure 4 and Figure 5 shown. The rotating shaft 10 drives the two turntables 15 to rotate counterclockwise. The two turntables 15 drive the first hollow shaft 16 and the second hollow shaft 17 to rotate counterclockwise with the rotating shaft 10 as the rotation center, as Figure 4 shown. The first hollow shaft 16 and the second hollow shaft 17 rotate counterclockwise through the cooperation of the first gear 20 and the ring outer gear 21; As Figure 6 shown, the first hollow shaft 16 and the second hollow shaft 17 respectively drive a group of two first cutting plates 18 and second cutting plates 19 to rotate counterclockwise. By rotating a group of two first cutting plates 18 and second cutting plates 19 counterclockwise, it is convenient to bring the hay material fed into the feed port of the crushing box 2 into the inside of the crushing box 2; The second cutting plate 19 moves relative to a set of two first cutting plates 18. That is, when the bottom end of the second cutting plate 19 moves into the pulverizing box 2, the top ends of the two lower first cutting plates 18 move out of the pulverizing box 2. When the top end of the second cutting plate 19 moves out of the pulverizing box 2, the bottom ends of the two upper first cutting plates 18 move into the pulverizing box 2. Through this setting, the hay can be cut and shredded; The external warm air blower is connected to the hot air duct 34 through an air pipe, and then warm air is sent into the interior of the hot air duct 34 as shown in Figure 1 by the warm air blower. The warm air blows downward into the interior of the pulverizing box 2 through the air outlet to dry the cut hay. It should be noted that when the hay is cut and shredded inside the pulverizing box 2, it will be stirred up and cut repeatedly as the first cutting plate 18 and the second cutting plate 19 move. The stirred-up hay is easier to dry. At the same time, the cut hay scraps will fall into the interior of the conveying cylinder 11 through the mesh holes of the sieve plate 13; As shown in Figure 1 and Figure 2 shown, the fourth belt pulley 8 is driven to rotate by the rotating shaft 10. The fourth belt pulley 8 drives the third belt pulley 7 to rotate through the second belt 9. The third belt pulley 7 drives the auger shaft 12 to rotate. The hay scraps that fall into the interior of the conveying cylinder 11 are conveyed to the interior of the collection box at the discharge end of the conveying cylinder 11 through the auger shaft 12, which is convenient for subsequent processing; As shown in Figure 4 by the arrow in the figure, when the two turntables 15 drive the first hollow shaft 16 to rotate counterclockwise with the rotating shaft 10 as the rotation center, the first spherical surface of the first sliding column 25 is driven to slide along the inclined surface of the driving ring 22 through the first hollow shaft 16. As shown in Figure 15 shown, because the end face of the driving ring 22 is inclined, and the thicker area of the inclined surface is arranged in the direction of the feed port of the pulverizing box 2, that is, as shown in Figure 3 shown, in the lower left area of the pulverizing box 2. Therefore, when the first spherical surface of the first sliding column 25 slides to the lower left area of the pulverizing box 2, the first sliding column 25 is extruded by the inclined surface of the driving ring 22 to move away from the driving ring 22; As shown in Figure 6 、 Figure 7 and Figure 8As shown, the first sliding column 25 drives one of the first cutter plates 18 away from the driving ring 22 through one of the sliding bars 24. One of the sliding bars 24 drives the other sliding bar 24 to move closer to the driving ring 22 through the cooperation of two racks 27 and the second gear 26, and the other sliding bar 24 drives the other first cutter plate 18 to move closer to the driving ring 22. Therefore, when a set of two first cutter plates 18 move to the area near the lower left of the crushing box 2, they will move closer to each other, reducing the distance between them, so that the distance between the second cutter plate 19 and the set of two first cutter plates 18 decreases. Through this device, the distance between the second cutter plate 19 and the set of two first cutter plates 18 can be reduced when they move to the area near the lower left of the crushing box 2, so that the hay can be cut and shredded smaller. On the contrary, when the first spherical surface of the first sliding column 25 rotates to the upper left area of the crushing box 2, because the first spherical surface moves to the thinner area segment of the inclined surface of the driving ring 22, the first sliding column 25 will move relatively closer to the driving ring 22. At this time, the first sliding column 25 drives one of the sliding bars 24 to move relatively closer to the driving ring 22. One of the sliding bars 24 drives the first cutter plates 18 on the outer surfaces of the two sliding bars 24 to move away from each other through the cooperation of two racks 27 and the second gear 26, so that the distance between the two first cutter plates 18 increases, and further the distance between the second cutter plate 19 and the adjacent two first cutter plates 18 increases. Because the hay feed enters the inside of the crushing box 2 through the feeding port area in the upper left of the crushing box 2 when it is shredded. At this time, because the distance between the second cutter plate 19 and the adjacent two first cutter plates 18 in the feeding port area in the upper left of the crushing box 2 is large, the larger cutting distance makes the initial cutting process not too violent. At the same time, the larger distance helps to process coarser or larger hay bales, preventing the hay bales from accumulating too much and causing jams or blockages, avoiding excessive friction between the second cutter plate 19 and the adjacent two first cutter plates 18 and the hay, reducing the load of the machine, and prolonging the service life of the equipment; As Figure 4 , Figure 6 , Figure 10 and Figure 11 As shown, when the two turntables 15 drive the second hollow shaft 17 to rotate counterclockwise around the rotating shaft 10, the second spherical surface of the second sliding column 32 slides along the inclined surface of the driving ring 22. When the second spherical surface of the second sliding column 32 moves to the area near the lower left of the crushing box 2, the second sliding column 32 is driven to move away from the driving ring 22 by the inclined surface of the driving ring 22, so that the second sliding column 32 drives the cross plate 30 to move away from the driving ring 22. The cross plate 30 drives the second guide post 2901 to move through the cooperation of the second inclined groove 3001 and the second guide post 2901, as Figure 12As shown, it drives the two drive plates 29 to move away from each other. Through the cooperation of the first inclined groove 2902 and the first guide post 2801 on the two drive plates 29, the diamond cutter 28 is driven to extend out of the telescopic groove 1901 and move, as Figure 12 , Figure 13 and Figure 14 shown. The cross-section of the diamond cutter 28 is diamond-shaped with two cutting edges; When the diamond cutter 28 extends out of the telescopic groove 1901, it can cut the first cutter plate 18 and the second cutter plate 19 which enter in a group of two. At the same time, the diamond cutter 28 extends out at the position of the feeding port at the lower left of the crushing box 2, so that the surface of the second cutter plate 19 protruding towards the inside of the crushing box 2 protrudes the diamond cutter 28. The protruding diamond cutter 28 can conveniently drive the hay into the crushing box 2, facilitating subsequent cutting; In the upper right area of the crushing box 2, when the second sliding column 32 moves to the thinner position of the driving ring 22 along with the turntable 15, the second sliding column 32 is not squeezed, so that the diamond cutter 28 retracts into the inside of the second cutter plate 19, making the surface of the second cutter plate 19 smooth and not protruding. When the hay is stirred and driven to the upper right of the crushing box 2, it will not be caught by the diamond cutter 28. Thus, the hot air blown out by the hot air pipe 34 can easily disperse the hay, facilitating the heat dissipation of the hay. While stirring, the smaller hay debris can be screened out from the mesh holes of the sieve plate 13.
