[0002] In animal husbandry, farmers usually choose some feed made from crops as raw materials for feeding. Feed crushing devices are mainly used to crush various feeds and various roughages. The purpose of feed crushing is to increase the surface area of ​​the feed and adjust the particle size. Increasing the surface area improves the palatability, and it is easy to contact with the digestive juice in the digestive tract, which is beneficial to improve the digestibility and better absorb the nutrients in the feed.

[0003] During the production and processing of feed, the raw materials are usually crushed and ground into powder. During the grinding process of feed raw materials, multiple procedures are required for crushing, crushing and grinding, and finally processed into fine powder. In many small processing equipment, crushing is generally carried out through a group of crushing mechanisms, which makes the raw materials not crushed sufficiently. In conventional technology, in order to make the crushing more sufficient, the crushing mechanism is often used with a filter screen, and a single filter screen structure is also prone to blockage during the crushing process, affecting the efficiency of feed processing.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0064] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0065] In one embodiment of the present invention, a device for processing and crushing straw raw materials for making livestock feed is provided, comprising a crushing section, a pulverizing section and a grinding section; in specific implementation, the crushing section is used to perform preliminary crushing of the straw raw materials and to break up and separate soil blocks and the like in the straw raw materials, and further, the straw raw materials after preliminary crushing are sent to the pulverizing section for pulverizing treatment, and the raw materials obtained by the pulverizing treatment are further finely ground by the grinding section to obtain feed for livestock breeding.

[0066] Specifically, Figure 1 and Figure 2 As shown, the straw raw material processing and crushing device for making livestock feed provided by the embodiment of the present disclosure includes a frame 2, which is used to provide support for the crushing part, the crushing part and the grinding part, wherein the crushing part is located above the grinding part, and the raw material crushed by the crushing part falls into the grinding part under the action of gravity for grinding to obtain refined feed; further, the crushing part is arranged on one side of the crushing part, and the straw raw material after preliminary crushing enters through the side of the crushing part.

[0067] Optional, such as Figure 1-Figure 3 As shown, the grinding part includes a grinding box 5, which is supported and fixed on the frame 2; a discharge nozzle 6 is provided at the bottom of the grinding box 5, and the discharge nozzle 6 is used to discharge the refined feed obtained by the grinding part; the grinding part provided by the present disclosure also includes a grinding shaft 8, which is transversely rotated and penetrated on the grinding box 5;

[0068] Furthermore, an engine 1 for driving the grinding shaft 8 to rotate is installed on the frame 2; optionally, the engine 1 provided in the present invention can be replaced by a high-power motor, without specific limitation, as long as it is a device that can provide driving force for the rotation of the grinding shaft 8.

[0069] like Figure 3 , Figure 14-16 As shown, in the embodiment of the present invention, the grinding part also includes a grinding cylinder 82, and the bottom rotation support of the grinding cylinder 82 is installed on the support 83, so that the grinding cylinder 82 can swing to a certain extent around the rotation support point at the bottom of the grinding cylinder 82 in the grinding box 5; wherein, a support foot 822 is fixedly provided at the bottom of the grinding cylinder 82, and the support foot 822 is rotationally connected to the support 83 through a connecting shaft.

[0070] Furthermore, the grinding part provided in the embodiment of the present invention further includes a grinding roller 81, which is located in the grinding cylinder 82, wherein the grinding roller 81 is coaxially fixedly mounted on the grinding shaft 8, and when the grinding shaft 8 rotates, the grinding roller 81 rotates synchronously;

[0071] Preferably, the outer surface of the grinding roller 81 has protrusions for improving the grinding effect so as to quickly grind the desired feed.

[0072] For further information, please refer to Figure 14-16 The two openings of the grinding cylinder 82 are both provided with side plates 823, and the two side plates 823 are both provided with disc cavities 8231, and the disc cavities 8231 are slidably connected with support discs 84, which are coaxially fixedly mounted on the grinding shaft 8. The purpose of this is to ensure that the grinding shaft 8 drives the grinding roller 81 to rotate while not affecting the angle change of the grinding cylinder 82 to a certain extent;

[0073] Among them, in the embodiment of the present invention, the grinding cylinder 82 with a changed angle can change the grinding contact point between the outer wall of the grinding roller 81 and the inner wall of the grinding cylinder 82. Such a change process can ensure sufficient grinding while causing the straw material located in the interlayer area between the outer wall of the grinding roller 81 and the inner wall of the grinding cylinder 82 to continuously change position, thereby further improving the grinding effect of the straw material in the interlayer.

[0074] Furthermore, a grinding through hole 821 is provided in the bottom area of ​​the grinding cylinder 82 for discharging finely ground feed particles.

[0075] Please continue reading Fig.14 and Fig.15 In the embodiment of the present invention, a push frame 85 is fixedly provided on one of the side plates 823, and the push frame 85 is vertically arranged. A rotating disk 71 is rotatably provided on the inner wall of the grinding box 5, and a stepper motor 7 for driving the rotating disk 71 to rotate is installed on the outer wall of the grinding box 5, wherein the output shaft of the stepper motor 7 is coaxially fixedly connected with the rotating disk 71; a push cylinder 72 is fixedly connected to the outer circumferential surface of the rotating disk 71, and the end of the push cylinder 72 slides against the push frame 85; in this embodiment, the stepper motor 7 is used to drive the rotating disk 71 to rotate, so that the push cylinder 72 moves in a circular path around the axis of the stepper motor 7. Movement allows the pushing cylinder 72 to push the pushing frame 85 to move, and then push the side plate 823 to swing to a certain extent, that is, the grinding cylinder 82 swings to a certain extent around the rotating support point at the bottom of the grinding cylinder 82 in the grinding box 5; of course, a motor with a servo function can also be directly used to directly drive the connecting support shaft to rotate, which has higher power requirements on the motor, and the motor needs to have forward and reverse rotation functions, and the swing amplitude requires precise control of the motor; therefore, the present invention uses a pushing cylinder 72 that performs circular motion to slide against the pushing frame 85, and a unidirectional motor can be used to achieve synchronous control of the swing amplitude, which has a better effect.

[0076] In some embodiments, the crushing section provided by the present invention includes a crushing box 4, and the bottom opening of the crushing box 4 is connected to the top opening of the grinding box 5 through a feeding channel 43. The straw raw material crushed by the crushing section falls into the grinding box 5 through the feeding channel 43. Specifically, the straw raw material crushed by the crushing section falls into the grinding cylinder 82 through the feeding channel 43; wherein, the lower end outlet of the feeding channel 43 is a circular arc top plate 431, and the top of the grinding cylinder 82 is connected to a material receiving funnel 86, and the upper end surface of the material receiving funnel 86 is an arc surface structure that is slidably sealed with the circular arc top plate 431. When the grinding cylinder 82 swings to a certain amplitude, the upper end surface of the material receiving funnel 86 slides along the circular arc top plate 431 for sealing, so that the straw raw material falling through the feeding channel 43 can pass through the material receiving funnel 86 and fall into the grinding cylinder 82.

[0077] Please continue to refer to Figure 3 , Figure 8-Figure 13 In the embodiment of the present invention, the pulverizing unit further comprises a rotating net cylinder 44 which is arranged in a transverse rotation in the pulverizing box 4, and a plurality of lifting rods 45 are arranged at equal intervals on the inner wall of the inner cavity of the rotating net cylinder 44, and the rotation of the rotating net cylinder 44 in the pulverizing box 4 is realized by a driving motor 41;

[0078] Among them, Figure 2 and Figure 3 As shown, a driving motor 41 is installed on the outer wall of the crushing box 4, and the output shaft of the driving motor 41 extends into the crushing box 4, and a driving gear 42 is installed at the end of the output shaft of the driving motor 41, and the driving gear 42 is meshed with the outer gear ring provided on the outer ring of the rotating net cylinder 44. In specific implementation, the started driving motor 41 is used to drive the driving gear 42 to rotate. Since the driving gear 42 is meshed with the outer gear ring provided on the outer ring of the rotating net cylinder 44, the rotating net cylinder 44 is driven to rotate in the crushing box 4. The rotating rotating net cylinder 44 can prevent the straw raw materials inside the rotating net cylinder 44 from being accumulated at the bottom all the time. In conjunction with the lifting rod 45, the straw raw materials in the rotating net cylinder 44 are continuously turned over, thereby improving the crushing effect of the straw raw materials.

[0079] In some embodiments, the crushing part provided by the present invention is located on one side outer wall of the crushing box 4, and the straw raw materials discharged from the crushing part directly enter the rotating net cylinder 44. It can be understood that Figure 3 As shown, the front and rear ends of the rotating net cylinder 44 are both through-opening structures. The front and rear ends of the rotating net cylinder 44 are directly rotatably mounted on the inner wall of the side plate of the crushing box 4, and the straw raw materials discharged from the crushing part directly pass through the side plate of the crushing box 4 and enter the rotating net cylinder 44.

[0080] In some embodiments, the crushing part provided by the present invention also includes a crushing shaft 9, which is horizontally penetrated and rotatably arranged on the crushing box 4, wherein the central axis of the crushing shaft 9 is colinear with the central axis of the rotating mesh cylinder 44, and the crushing shaft 9 is connected to the grinding shaft 8 through a transmission belt 11. When the engine 1 is started to drive the grinding shaft 8 to rotate, the crushing shaft 9 is driven to rotate under the linkage cooperation of the transmission belt 11.

[0081] like Figure 8-Figure 13 As shown, the crushing part provided by the present invention also includes a plurality of circular seats 94, and the plurality of circular seats 94 are fixedly arranged in the crushing box 4 at equal intervals. Specifically, the circular seat 94 located at the rear end is fixedly connected to the rear inner wall of the crushing box 4, so that the circular seat 94 will not rotate; the crushing part of the present invention also includes a first crushing shaft 91 and a second crushing shaft 92, the first crushing shaft 91 passes through the plurality of circular seats 94 in sequence, and the first crushing shaft 91 can rotate freely relative to the plurality of circular seats 94; correspondingly, the second crushing shaft 92 also passes through the plurality of circular seats 94 in sequence, and the second crushing shaft 92 can rotate freely relative to the plurality of circular seats 94; further, a first gear is coaxially fixedly installed at the end of the first crushing shaft 91, and a second gear is coaxially fixedly installed at the end of the second crushing shaft 92; a third gear is coaxially fixedly installed on the crushing shaft 9, wherein the first gear is meshedly connected with one side of the third gear, and a transmission gear 9 is also rotatably arranged on the circular seat 94. 3. The second gear is meshed with one side of the transmission gear 93, and the other side of the transmission gear 93 is meshed with the other side of the third gear. Such a gear meshing structure can make the first crushing shaft 91 and the second crushing shaft 92 rotate in the same direction, and when the rotation direction of the crushing shaft 9 is counterclockwise, the rotation direction of the first crushing shaft 91 and the second crushing shaft 92 is clockwise; further, the crushing shaft 9 located between the two adjacent circular seats 94 is equipped with a second crushing roller 96, and the first crushing shaft 91 and the second crushing shaft 92 located between the two adjacent circular seats 94 are both equipped with a first crushing roller 95. The first crushing roller 95 and the second crushing roller 96 are alternately arranged. When the crushing shaft 9, the first crushing shaft 91 and the second crushing shaft 92 are all rotating, the first crushing roller 95 and the second crushing roller 96 can be driven to rotate relatively at the same time, and the straw raw materials falling on the first crushing roller 95 and the second crushing roller 96 are crushed and preliminarily ground.

[0082] Further, a circular cover 46 is coaxially rotatably sleeved on the outer circumferential surface of each circular seat 94, and a plurality of mounting screw holes 461 are formed in a circular array at equal intervals on the circular cover 46, and a plurality of crushing knives 47 are mounted on the circular cover 46, wherein an arc cover 471 is fixedly welded and provided at the root of the crushing knives 47, and when the arc cover 471 is sleeved on the circular cover 46, a screw rod 48 matched with the mounting screw hole 461 passes through the plurality of circular covers 46 in sequence, and the arc cover 471 is fixed on the circular cover 46 by a fastening nut 481 matched with the screw rod 48; the screw rod 48 is provided, so that the plurality of circular covers 46 can be moved at the same time, so as to drive the crushing knives 47 to rotate, thereby realizing the crushing action of the straw raw material;

[0083] As a preference, Figure 3 and Fig. 9 As shown, the lifting rod 45 provided in the embodiment of the present disclosure is an arc-shaped rod structure, the arc-shaped concave surface of the lifting rod 45 faces the direction opposite to the rotation direction of the annular cover 46, and the movement path of the crushing knife 47 passes through the gap between two adjacent lifting rods 45 on the same layer, that is, the crushing knife 47 can pass through the gap between two adjacent lifting rods 45 on the same layer, so that when the lifting rod 45 lifts the straw raw material upward, the high-speed rotating crushing knife 47 passes through the gap to crush the straw raw material lifted by the lifting rod 45; in addition, Figure 3 Taking the state shown as an example, the rotating mesh drum 44 is in a clockwise rotating state, and the annular cover 46 is in a counterclockwise rotating state. During the upward movement of the straw raw material lifted by the lifting rod 45, it will be cut by the crushing knife 47. After the cut straw raw material lifted by the lifting rod 45 moves to the top, the lifted straw raw material can fall onto the first crushing roller 95 and the second crushing roller 96 to achieve further crushing and preliminary grinding processing.

[0084] Therefore, in the crushing section of the present invention, while the rotating mesh drum 44 causes the lifting rod 45 to lift the straw raw material upward, the crushing knife 47 passes through the gap and cuts the straw raw material lifted by the lifting rod 45. After the lifting rod 45 lifts the cut straw raw material and moves it to the top, the straw raw material falls onto the first crushing roller knife 95 and the second crushing roller knife 96.

[0085] In an optional embodiment, the annular cover 46 located at the front end (also called the outermost side) is coaxially fixedly connected to the crushing shaft 9. For example, the annular cover 46 and the crushing shaft 9 are fixedly connected by multiple support rods, so that when the crushing shaft 9 rotates, the annular cover 46 is synchronously driven to rotate. When the annular cover 46 rotates, it drives the crushing knife 47 to move and cut the straw material in the rotating net cylinder 44.

The feeding window 321 is directly connected to the inner cavity of the rotating net cylinder 44, so that the straw material in the horizontal barrel 32 enters the rotating net cylinder 44 through the feeding window 321. The movable net cylinder 44; further, a motor shaft 341 is coaxially rotatably arranged in the horizontal barrel 32, and a forward and reverse servo motor 34 for driving the motor shaft 341 to rotate is installed on the outer wall of the feed box 31, and a plurality of second sleeves 342 are coaxially fixedly installed on the motor shaft 341, and a plurality of crushing rods 343 are arranged on the outer ring of each second sleeve 342; a first sleeve 323 is coaxially slidably sleeved on the motor shaft 341 between two adjacent second sleeves 342, and each first sleeve 323 is connected to the feeding window 321 through a guide plate 322, so that when the motor shaft 341 rotates, the crushing rod 343 is driven to rotate, and the crushing rod 343 continuously passes through the area between two adjacent guide plates 322;

[0087] Preferably, one side of the breaker rod 343 provided in the embodiment of the present invention has a blade, and specifically, the blade is arranged in the direction in which the breaker rod 343 rotates clockwise; the forward and reverse servo motor 34 in the embodiment of the present invention has a forward and reverse function, such as Figure 5 As shown, when the motor shaft 341 rotates counterclockwise, the straw material in the horizontal barrel 32 can be lifted up to the guide plate 322, and the straw material further slides along the guide plate 322 to the feeding window 321 to enter the rotating net cylinder 44; on the contrary, when there is no need to add straw material to the rotating net cylinder 44, the motor shaft 341 can be rotated clockwise to drive the breaking rod 343 to rotate clockwise. Since the breaking rod 343 has a blade on one side in the clockwise direction and due to the existence of the guide plate 322, when the clockwise rotating breaking rod 343 pushes the straw material to pile on the lower end of the guide plate 322, the blade cuts the straw material to achieve preliminary crushing of the straw material; in addition, the present invention can break up the soil blocks on the straw material through the action of the breaking rod 343, and the soil residue passes through the residue collecting mesh 324 and is collected in the residue collecting box 33.
