Description

[0002] In animal husbandry, hay is indispensable as feed for cattle and sheep. Hay is a major food for animals, but hay is relatively fluffy and requires a large amount of storage space for storage. Therefore, the hay needs to be crushed before it can be stored, and the crushed hay is easier to feed animals.

[0003] When the existing hay cutting and shredding device is in use, the cutting blades cut the hay multiple times to make it into shorter hay pieces. Since the distance between the cutting blades in the existing device is fixed, the cutting blades cut the hay into the smallest segments as soon as it enters the shredder box, causing the cutting blades to bear greater cutting resistance at the beginning, causing the machine to bear a greater cutting load, which can easily cause damage to the machine and shorten the normal service life of the machine.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] Because the cutting blade needs to bear a large cutting load when the hay bundle is just cut and crushed, in order to solve this problem, the present application discloses a hay feed crushing and drying device, such as Figure 1-Figure 3 As shown, it includes: 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 therewith, and a cutting and crushing component for cutting and crushing hay.

[0041] The cutting and crushing assembly is arranged inside the crushing box 2, and the cutting and crushing assembly includes: a rotating shaft 10 rotatably installed between the inner walls of the crushing box 2 on opposite sides, two rotating discs 15 are symmetrically fixedly installed on the outer surface of the rotating shaft 10, and multiple first hollow shafts 16 are equidistantly installed for rotation in the circumferential direction between the two rotating discs 15. Multiple second hollow shafts 17 are also equidistantly installed for rotation in the circumferential direction between the two rotating discs 15. The multiple first hollow shafts 16 and the multiple second hollow shafts 17 are alternately arranged with each other, and multiple groups of first cutting plates 18 are equidistantly slidably installed in groups of two on the outer surface of the first hollow shafts 16. Multiple second cutting plates 19 are equidistantly fixedly installed on the outer surface of the second hollow shafts 17. The second cutting plate 19 is arranged between a group of two first cutting plates 18. Multiple telescopic grooves 1901 are symmetrically opened on the outer surface of the opposite side of the second cutting plate 19. The inner walls of the multiple telescopic grooves 1901 are all slidably installed with diamond-shaped cutting knives 28, which are used to cut hay.

[0042] In order to facilitate the understanding of the directions mentioned in the instructions, Figure 1 As shown, the side of the device where the first pulley 4 is located is the front view. Because the rotating shaft 10 is located inside the crushing box 2, the center of the rotating shaft 10 is the center of the front view. The horizontal plane where the center of the rotating shaft 10 is located is the top of the crushing box 2, and the vertical plane where the center of the rotating shaft 10 is located is the left side of the crushing box 2, and the vertical plane where the center of the rotating shaft 10 is located is the right side of the crushing box 2. The feed port of the crushing box 2 is located on the left side of the crushing box 2.

[0043] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the two turntables 15 are driven to rotate counterclockwise by the rotating shaft 10, and 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 shown in FIG. Figure 4As shown, the first hollow shaft 16 and the second hollow shaft 17 rotate counterclockwise by the cooperation of the first gear 20 and the annular outer gear 21, and the second cutting plate 19 moves relative to each other between a group of two first cutting plates 18, that is, the two ends of the second cutting plate 19 and the end adjacent to the group of two first cutting plates 18 move relative to each other, thereby generating a shearing motion. Through this arrangement, hay can be cut and chopped.

[0044] In this embodiment, the adjustment component is used to adjust the distance between a group of two first cutting plates 18. The adjustment component is arranged inside the first hollow shaft 16. The adjustment component includes: a fixed plate 23 fixedly installed between the inner walls of the first hollow shaft 16, and the outer surface of the fixed plate 23 on one side of the rotating shaft 10 is symmetrically provided with two dovetail grooves 2301, and the inner walls of the two dovetail grooves 2301 are slidably installed with slides 24. The inner walls of a group of two first cutting plates 18 are fixedly installed with a limiting slider 1801, and the outer surface of the first hollow shaft 16 is provided with multiple groups of limiting slides 1601 equidistantly in pairs. A group of two limiting slides 1801 are respectively slidably installed with the inner walls of a group of two limiting slides 1601, and the other ends of a group of two limiting slides 1801 pass through the inner wall of the first hollow shaft 16 and are respectively fixed to the outer surfaces of the two slides 24. The upper surface of the fixed plate 23 near one end of the first pulley 4 is provided with a The second gear 26 is rotatably mounted on the upper surface of the fixing plate 23 near the middle position, and the outer surfaces of the adjacent ends of the two slide bars 24 are fixedly mounted with a rack 27, and the rack 27 meshes with the second gear 26. The crushing box 2 is fixedly mounted with a driving ring 22 near the inner wall of the annular outer gear 21, and the end face of the driving ring 22 is provided with an inclined surface, and the other end of the first sliding post 25 is provided with a first spherical surface, and the first spherical surface at the other end of the first sliding post 25 is against the inclined surface of the driving ring 22.

[0045] like Figure 4 As shown by the middle arrow, 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 by the first hollow shaft 16 to slide along the inclined surface of the driving ring 22, as shown in FIG. Figure 15 As shown, because the end surface of the drive ring 22 is inclined, and the thicker area of the inclined surface is set in the area below the left side of the crushing box 2, that is, Figure 3 and Figure 4As shown in FIG. 2 , when the first spherical surface of the first slide post 25 rotates to the lower left area of the crushing box 2, the first spherical surface of the first slide post 25 is squeezed by the inclined surface of the drive ring 22, so that the first slide post 25 moves relatively away from the drive ring 22. Figure 6 、 Figure 7 and Figure 8 As shown, the first slide column 25 drives one of the first cutting plates 18 to move away from the drive ring 22 through one of the slide bars 24, and one of the slide bars 24 drives the other slide bar 24 to move close to the drive ring 22 through the cooperation of the two racks 27 and the second gear 26, and the other slide bar 24 drives the other first cutting plate 18 to move close to the drive ring 22. Therefore, when a group of two first cutting plates 18 move to the area near the lower left of the crushing box 2, they will move close to each other to shorten the distance between them, thereby reducing the distance between the second cutting plate 19 and the group of two first cutting plates 18. Through this device, the distance between the second cutting plate 19 and the group of two first cutting plates 18 can be reduced when they move to the area below the left of the crushing box 2, so that the hay can be cut and chopped smaller.

[0046] On the contrary, when the turntable 15 rotates and drives the first spherical surface of the first slide post 25 to rotate to the upper left area of the crushing box 2, because the first spherical surface moves to the thinner area of the inclined surface of the drive ring 22, the first slide post 25 will move relatively close to the drive ring 22. At this time, the first slide post 25 drives one of the slide bars 24 to move relatively close to the drive ring 22. One of the slide bars 24 drives the first cutting plates 18 on the outer surfaces of the two slide bars 24 to move away from each other through the cooperation of the two racks 27 and the second gear 26, thereby increasing the distance between the two first cutting plates 18, and further causing the second cutting plate 19 to be closer to the two adjacent first cutting plates 18. The spacing between the cutting plates 18 is increased because when the hay feed is chopped, it enters the inside of the crushing box 2 through the upper left feed port area of the crushing box 2. At this time, because the distance between the second cutting plate 19 in the upper left feed port area of the crushing box 2 and the two adjacent first cutting plates 18 is large, the larger cutting spacing makes the initial cutting process not too intense. At the same time, the larger distance helps to process rougher or larger hay bundles, prevents excessive accumulation of hay bundles causing jamming or blockage, avoids excessive friction between the second cutting plate 19 and the two adjacent first cutting plates 18 and the hay, reduces the load on the machine, and extends the service life of the equipment.

[0047] In this embodiment, the control component is used to control the diamond-shaped cutting knife 28 to extend and retract the outer surface of the second cutting 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. The inner wall of the second hollow shaft 17 is symmetrically provided with two sliding grooves 1702. The two sides of the cross plate 30 are respectively slidably mounted with the inner walls of the two sliding grooves 1702. The upper surfaces of the other two sides of the cross plate 30 are symmetrically provided with a plurality of second inclined grooves 3001. The outer surfaces of the second cutting plate 19 at both ends are provided with a plurality of second inclined grooves 3001. There are two symmetrical mounting grooves 1902, and the interiors of the two mounting grooves 1902 are both provided with drive plates 29. The adjacent ends of the two drive plates 29 penetrate the inner wall of the second cutting plate 19 and are slidably mounted thereon. The outer surface of the second hollow shaft 17 is equidistantly penetrated by a plurality of groups of jacks 1701 in pairs. The adjacent ends of the two drive plates 29 respectively penetrate a group of two jacks 1701 and are slidably mounted thereon. The inner walls of the adjacent ends of the two drive plates 29 are both fixedly mounted with second guide posts 2901. The second guide posts 2901 and the second inclined groove 3001 are aligned with each other. The inner wall is slidably installed, and an opening 2903 is provided inside the two drive plates 29. The diamond cutter 28 is arranged inside the opening 2903 and is slidably installed on the inner wall of the opening 2903. The outer surfaces of the two drive plates 29 are equidistantly penetrated with a plurality of first inclined grooves 2902. The bottom end of the diamond cutter 28 is fixedly installed with a first guide column 2801. The first guide column 2801 is slidably installed with the inner wall of the first inclined groove 2902. The cross plate 30 is fixedly installed with a second sliding column 32 on one end close to the drive ring 22. The inner wall of one end of the second hollow shaft 17 is fixedly installed. A mounting plate 31 is installed, one end of the second slide post 32 passes through the outer surface of the mounting plate 31 and is slidably installed therewith, a limit ring 3201 is fixedly installed on the outer surface of the second slide post 32 near one end of the drive ring 22, and a first spring 33 is sleeved on the outer surface of the second slide post 32, one end of the first spring 33 is fixedly connected to the outer surface of the limit ring 3201, and the other end of the first spring 33 is fixedly connected to the outer surface of the mounting plate 31, and a second spherical surface is provided at the other end of the second slide post 32, and the second spherical surface at the other end of the second slide post 32 is against the inclined surface of the drive ring 22.

[0048] like 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 with the rotating shaft 10 as the rotation center, the second hollow shaft 17 drives the second spherical surface of the second slide post 32 to slide along the inclined surface of the drive ring 22. When the second spherical surface of the second slide post 32 moves to the lower left area of the crushing box 2, the inclined surface of the drive ring 22 squeezes the second slide post 32, driving the second slide post 32 to move away from the drive ring 22, so that the second slide post 32 drives the cross plate 30 to move away from the drive ring 22. The cross plate 30 cooperates with the second inclined groove 3001 and the second guide post 2901, as shown in FIG. Figure 12 As shown, the two drive plates 29 are driven to move away from each other. The two drive plates 29 cooperate with the first inclined groove 2902 and the first guide column 2801 to drive the diamond cutter 28 to extend out of the telescopic slot 1901, as shown in FIG. Figure 12 、 Figure 13 and Figure 14 As shown, the cross section of the diamond-shaped cutting knife 28 is a diamond with two cutting edges.

[0049] When the diamond-shaped cutter 28 extends out of the telescopic slot 1901, the hay bundle entering between a group of two first cutting plates 18 and the second cutting plates 19 can be cut. At the same time, the diamond-shaped cutter 28 is extended from the feed port at the lower left of the crushing box 2, so that the diamond-shaped cutter 28 protrudes from the surface of the second cutting plate 19 moving toward the inside of the crushing box 2. The protruding diamond-shaped cutter 28 can easily drive the hay into the inside of the crushing box 2, which is convenient for subsequent cutting.

[0050] When in the upper right area of the crushing box 2, the second slide post 32 moves to the thinner position of the drive ring 22, so the second slide post 32 is not squeezed, so that the diamond cutter 28 retracts into the inside of the second cutting plate 19. Since the diamond cutter 28 and the telescopic slot 1901 are matched, there will not be too large a gap between the two, thereby preventing hay debris from entering the inside of the telescopic slot 1901. At the same time, after the diamond cutter 28 is retracted into the telescopic slot 1901, the end face of its top is flush with the outer surface of the second cutting plate 19, so that the surface of the second cutting plate 19 is smooth and not raised, so that the hay will not be caught by the diamond cutter 28 when it is stirred and driven to the upper right side of the crushing box 2, so that the hot air blown out by the hot air pipe 34 can easily blow away the hay, which is convenient for dissipating the heat of the hay. While stirring, smaller hay debris can be screened out from the mesh of the screen plate 13.

[0051] 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, and a first pulley 4 is fixedly installed on the output end of the driving motor 3. One end of the rotating shaft 10 passes through the outer surface of the crushing box 2 and is fixedly installed with a second pulley 5. The outer surfaces of the first pulley 4 and the second pulley 5 are wrapped with a first belt 6. The ends of multiple first hollow shafts 16 and multiple second hollow shafts 17 close to the first pulley 4 all pass through the outer surface of one of the turntables 15 and are fixedly installed with a first gear 20. A circular outer gear 21 is fixedly installed on the inner wall of the crushing box 2 near the first gear 20, and the first gear 20 is meshed with the circular outer gear 21. Two guards 14 are symmetrically fixedly installed on the inner walls of the opposite sides of the crushing box 2, and the two turntables 15 are arranged inside the two guards 14. The first gear 20 and the circular outer gear 21 are protected by the guards 14 to prevent them from being exposed to the external environment.

[0052] In this embodiment, a conveying drum 11 is fixedly installed at the bottom of the crushing box 2, and an auger shaft 12 is rotatably installed on the inner wall of the conveying drum 11 near one end of the second pulley 5. One end of the auger shaft 12 passes through the outer surface of the conveying drum 11 and is fixedly installed with a third pulley 7. A fourth pulley 8 is also fixedly installed at one end of the rotating shaft 10. A second belt 9 is wound around the outer surfaces of the fourth pulley 8 and the third pulley 7. The interior of the conveying drum 11 is connected to the interior of the crushing box 2, and 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 conveying drum 11 and the crushing box 2.

[0053] When the hay is cut and chopped inside the crushing box 2, it will be stirred up and cut back and forth multiple times as the first cutting plate 18 and the second cutting plate 19 move. The stirred hay is easier to dry. At the same time, the cut and chopped hay will fall from the mesh of the screen plate 13 into the interior of the conveyor cylinder 11, as shown in FIG. Figure 1 and Figure 2 As shown, the fourth pulley 8 is driven to rotate by the rotating shaft 10, the fourth pulley 8 drives the third pulley 7 to rotate through the second belt 9, and the third pulley 7 drives the auger shaft 12 to rotate, and the hay clippings falling into the conveyor cylinder 11 are conveyed to the collection box at the discharge end of the conveyor cylinder 11 through the auger shaft 12 for subsequent processing.

[0054] In this embodiment, a group of two first cutting plates 18 are provided with sheaths at opposite ends. When the first cutting plates 18 slide, the sheaths can prevent the limiting slide groove 1601 from being exposed to the external environment, thereby preventing the crushed hay from entering the interior of the first hollow shaft 16.

[0055] The working principle of the present invention is that when in use, the operator transports the hay material to the feed port of the crushing box 2 manually or with a feeding belt, and then drives the first pulley 4 to rotate through the driving motor 3, and the first pulley 4 drives the second pulley 5 to rotate through the first belt 6, and the second pulley 5 drives the rotating shaft 10 to rotate. Figure 4 and Figure 5 As shown, the rotating shaft 10 drives the two rotating disks 15 to rotate counterclockwise, and the two rotating disks 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. Figure 4 As shown, the first hollow shaft 16 and the second hollow shaft 17 rotate counterclockwise by themselves through the cooperation of the first gear 20 and the annular outer gear 21;

[0056] like Figure 6 As shown, the first hollow shaft 16 and the second hollow shaft 17 respectively drive a set of two first cutting plates 18 and a second cutting plate 19 to rotate counterclockwise. Through the counterclockwise rotation of the set of two first cutting plates 18 and the second cutting plates 19, the hay fed into the feed port of the crushing box 2 is brought into the interior of the crushing box 2.

[0057] The second cutting plate 19 moves relative to the two first cutting plates 18 in a group. That is, when the bottom end of the second cutting plate 19 moves into the crushing box 2, the top ends of the two first cutting plates 18 located below move out of the crushing box 2. When the top end of the second cutting plate 19 moves out of the crushing box 2, the bottom ends of the two first cutting plates 18 located above move into the crushing box 2. This arrangement can cut and shred hay.

[0058] The external heater is connected to the hot air pipe 34 through the air pipe, and then the heat is sent to the Figure 1 Warm air is supplied to the interior of the hot air pipe 34 shown, and the warm air is blown downwardly into the interior of the crushing box 2 through the air outlet to dry the cut hay. It should be noted that when the hay is cut and chopped inside the crushing box 2, it is stirred and cut back and forth multiple times as the first cutting plate 18 and the second cutting plate 19 move. The stirred hay is more easily dried. At the same time, the cut and chopped hay scraps fall through the mesh of the sieve plate 13 into the interior of the conveyor cylinder 11.

[0059] like Figure 1 and Figure 2 As shown, the fourth pulley 8 is driven to rotate by the rotating shaft 10, the fourth pulley 8 drives the third pulley 7 to rotate through the second belt 9, and the third pulley 7 drives the auger shaft 12 to rotate, and the hay clippings falling into the conveyor cylinder 11 are conveyed to the collection box at the discharge end of the conveyor cylinder 11 through the auger shaft 12 for subsequent processing;

[0060] like Figure 4 As shown by the middle arrow, 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 by the first hollow shaft 16 to slide along the inclined surface of the driving ring 22, as shown in FIG. Figure 15 As shown, because the end face of the driving ring 22 is inclined, and the thicker area of the inclined face is arranged in the direction of the feed opening of the crushing box 2, that is, Figure 3 As shown, the lower left area of the crushing box 2, so when the first spherical surface of the first slide post 25 slides to the lower left area of the crushing box 2, the inclined surface of the drive ring 22 squeezes the first slide post 25 away from the drive ring 22;

[0061] like Figure 6 、 Figure 7 and Figure 8As shown, the first slide post 25 drives one of the first cutting plates 18 to move away from the drive ring 22 through one of the slide bars 24, and one of the slide bars 24 drives the other slide bar 24 to move closer to the drive ring 22 through the cooperation of the two racks 27 and the second gear 26, and the other slide bar 24 drives the other first cutting plate 18 to move closer to the drive ring 22. Therefore, when a group of two first cutting plates 18 moves to the area near the lower left of the crushing box 2, they will move closer to each other to shorten the distance between them, thereby reducing the distance between the second cutting plate 19 and the group of two first cutting plates 18. Through this device, the distance between the second cutting plate 19 and the group of two first cutting plates 18 can be reduced when the second cutting plate 19 and the group of two first cutting plates 18 move to the area below the left of the crushing box 2, thereby making the hay cut and chopped smaller. On the contrary, when the first spherical surface of the first slide post 25 rotates to the upper left area of the crushing box 2, because the first spherical surface moves to the thinner area of the inclined surface of the drive ring 22, the first slide post 25 will move relatively close to the drive ring 22. At this time, the first slide column 25 drives one of the slide bars 24 to move in the direction relatively close to the drive ring 22, and one of the slide bars 24 drives the first cutting plates 18 on the outer surfaces of the two slide bars 24 to move away from each other through the cooperation of the two racks 27 and the second gear 26, thereby increasing the distance between the two first cutting plates 18, and then increasing the distance between the second cutting plate 19 and the two adjacent first cutting plates 18. Because the hay feed enters the crushing box 2 through the upper left feed inlet area of the crushing box 2 when being chopped, at this time, because the distance between the second cutting plate 19 and the two adjacent first cutting plates 18 in the upper left feed inlet area 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 is helpful to process rougher or larger hay bundles, prevents hay bundles from being stuck or blocked due to excessive accumulation, avoids excessive friction between the second cutting plate 19 and the two adjacent first cutting plates 18 and the hay, reduces the load of the machine, and extends the service life of the equipment;

[0062] like 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 with the rotating shaft 10 as the rotation center, the second hollow shaft 17 drives the second spherical surface of the second slide post 32 to slide along the inclined surface of the drive ring 22. When the second spherical surface of the second slide post 32 moves to the lower left area of the crushing box 2, the inclined surface of the drive ring 22 squeezes the second slide post 32, driving the second slide post 32 to move away from the drive ring 22, so that the second slide post 32 drives the cross plate 30 to move away from the drive ring 22. The cross plate 30 cooperates with the second inclined groove 3001 and the second guide post 2901, as shown in FIG. Figure 12As shown, the two drive plates 29 are driven to move away from each other. The two drive plates 29 cooperate with the first inclined groove 2902 and the first guide column 2801 to drive the diamond cutter 28 to extend out of the telescopic slot 1901, as shown in FIG. Figure 12 、 Figure 13 and Figure 14 As shown, the cross section of the diamond-shaped cutting knife 28 is a diamond with two cutting edges;

[0063] When the diamond-shaped cutting blade 28 extends out of the telescopic slot 1901, it can cut the first cutting plate 18 and the second cutting plate 19 that enter the set of two. At the same time, the diamond-shaped cutting blade 28 is extended at the position of the feed opening at the lower left of the crushing box 2, so that the diamond-shaped cutting blade 28 protrudes from the surface of the second cutting plate 19 that moves toward the inside of the crushing box 2. The protruding diamond-shaped cutting blade 28 can easily drive the hay into the crushing box 2, which is convenient for subsequent cutting.

[0064] When in the upper right area of the crushing box 2, when the second slide post 32 moves with the turntable 15 to the thinner position of the drive ring 22, the second slide post 32 is not squeezed, so that the diamond cutter 28 retracts into the inside of the second cutting plate 19, making the surface of the second cutting plate 19 smooth and not protruding, so that the hay will not be caught by the diamond cutter 28 when it is stirred and driven to the upper right of the crushing box 2, so that the hot air blown out by the hot air pipe 34 can easily blow away the hay, which is convenient for dissipating the heat of the hay. While stirring, smaller hay debris can be screened out from the mesh of the screen plate 13.
