Description

Technical Field

[0001] The present invention relates to the technical field of crushing equipment, and particularly to a crushed alfalfa material crushing equipment with a pretreatment mechanism. Background Art

[0002] Alfalfa, also known as purple-flowered alfalfa, is a general term for plants of the genus Medicago in the legume family. Alfalfa likes sunlight and humidity and has strong vitality. Alfalfa has small leaves with fine teeth on the upper edge of the small leaves, and the stipules are attached to the base of the petiole; the flowers are very small, yellow or purple, forming a short raceme or head inflorescence, axillary; the calyx teeth are nearly equal in length, and the standard petal is oblong and obovate. Alfalfa grows in fields, roadsides, wastelands, grasslands, riverbanks, valleys and other places. Alfalfa contains bioactive substances such as alfalfa polysaccharides, saponins, flavonoids and unknown growth promoting factors, and has biological functions such as improving the production performance of livestock and poultry and improving the body's immune function. Therefore, alfalfa is usually used as a raw material for feed and forage. After drying alfalfa, it is necessary to crush the dried alfalfa for subsequent use as a feed raw material, so an alfalfa material crushing equipment is needed.

[0003] At present, traditional alfalfa material crushing equipment is not convenient for pretreating alfalfa materials. Some longer alfalfa materials will be wound around the crushing parts, and it is easy to cause the equipment to jam due to winding, resulting in low crushing efficiency and affecting the crushing of alfalfa materials by the equipment. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A crushed alfalfa material crushing equipment with a pretreatment mechanism, comprising:

[0006] A casing, and a power source installed in the middle of the surface of the casing, and a cutting mechanism is installed in the middle of the top of the casing;

[0007] The cutting mechanism includes a barrel and a servo motor. The barrel is fixedly installed in the middle of the top of the machine shell, and the servo motor is fixedly installed in the middle of the top of the barrel. A feed hopper is installed at the top of the surface of the barrel. A rotating shaft is rotatably installed in the middle of the interior of the barrel. A material distributing component is installed at the top of the outer cylindrical surface of the rotating shaft. A cutting knife is fixedly connected to the middle of the outer cylindrical surface of the rotating shaft. A bent connecting rod is fixedly connected to the bottom end of the rotating shaft. A cylinder is rotatably installed at the bent part of the bottom of the bent connecting rod. By rotating the output end of the servo motor, the rotating shaft can be driven to rotate, so that the cutting knife rotates with the rotating shaft, and the alfalfa material is put into the interior of the barrel from the feed hopper. As the alfalfa material moves downward, the alfalfa material can be cut by the rotation of the cutting knife. Combined with the fact that the cutting knives are evenly distributed on the outer cylindrical surface of the rotating shaft, the alfalfa material can be continuously cut, so that the longer alfalfa material is cut into small sections and is not easily entangled;

[0008] The material processing mechanism is used for crushing alfalfa materials and is installed in the middle of the inner cavity of the machine shell;

[0009] Among them, the material processing mechanism includes a receiving hopper and a rotating roller. The receiving hopper is fixedly installed in the middle of the inner cavity of the machine shell. The rotating roller is rotatably installed in the middle of the top of the receiving hopper. A leakage hole is opened in the middle of the bottom of the receiving hopper. Triangular teeth are fixedly connected to the bottom of the inner cavity of the receiving hopper. Rotating blades are fixedly connected to the outer cylindrical surface of the rotating roller. A swinging component is installed at the top of the inner side surface of the receiving hopper. By rotating the output end of the power source, the rotating roller can be driven to rotate, so that the rotating blades are driven to rotate in a circular motion, and the pre-treated and cut alfalfa materials can be crushed. And by arranging the rotating blades and the triangular teeth in an alternating manner, the alfalfa materials can be quickly crushed, and the crushed alfalfa materials leak from the leakage hole, while the uncrushed alfalfa materials are left to continue to be crushed, so that the alfalfa materials are evenly crushed.

[0010] Preferably, the cutting knives are evenly distributed in the middle of the outer cylindrical surface of the rotating shaft. There are two bent connecting rods, and the two bent connecting rods are symmetrically installed along the rotating shaft. The bottom ends of the bent connecting rods pass through the center of the cylinder.

[0011] Preferably, the material feeding assembly includes an arc-shaped convex block and a conical shell. The bottom end of the arc-shaped convex block is fixedly connected to the inner wall of the barrel. The center of the conical shell is fixedly connected to the outer circular surface of the rotating shaft. A material feeding rod is slidably installed at the conical surface of the conical shell. The arc-shaped convex block and the material feeding rod are installed at the same height. A elastic sheet is fixedly connected between the top end of the material feeding rod and the outer circular surface of the rotating shaft, and the elastic sheet is installed inside the conical shell. Supported by the conical shell and driven by the rotating shaft to rotate the conical shell, the material feeding rod will rotate with the conical shell. Then, by the rotation of the material feeding rod, the alfalfa grass material put in from the feed hopper can be stirred to promote the alfalfa grass material to enter the inside of the barrel, which is convenient for subsequent pretreatment of the alfalfa grass material.

[0012] Preferably, the rotating shaft passes through the center of the conical shell. The bottom end of the material feeding rod penetrates the inner wall of the conical shell and extends to its outside. There are three material feeding rods, and the three material feeding rods are evenly distributed on the surface of the conical shell. As the material feeding rod stirs the alfalfa grass material, the alfalfa grass material enters the barrel and slides downwards. And through the continuous rotation of the material feeding rod, when the bottom end of the material feeding rod contacts the surface of the arc-shaped convex block, the material feeding rod receives an upward oblique pushing force, so that the material feeding rod slides into the conical shell, and the elastic sheet is compressed. Along with the contraction of the material feeding rod sliding into the conical shell, the alfalfa grass material remaining on the surface of the material feeding rod falls off.

[0013] Preferably, the rotating roller is fixedly installed with the output end of the power source through a coupling, and the material leakage holes and the triangular teeth are arranged alternately.

[0014] Preferably, the rotary blade is installed directly above the material leakage hole, and the rotary blades are evenly distributed on the outer circular surface of the rotating roller. A cutting edge surface is opened at the edge of the surface of the triangular tooth.

[0015] Preferably, the swinging assembly includes a rectangular hole and a support rod. The rectangular hole is opened at the side of the bottom of the material receiving hopper. The support rod is rotatably installed at the top of the material receiving hopper. An arc-shaped force receiving rod is fixedly connected to the middle of the top of the outer circular surface of the support rod. A swinging rod is fixedly connected to the outer circular surface of the support rod. The swinging rod and the rotary blade are arranged alternately. An elastic reset ring is fixedly connected between the bottom of the swinging rod and the bottom of the inner cavity of the material receiving hopper. By applying a pushing force to the support rod through the arc-shaped force receiving rod, the swinging rod rotates and adjusts the angle towards the bottom position of the inner cavity of the material receiving hopper, and the elastic reset ring is compressed;

[0016] As the rotating shaft drives the bent connecting rod to continuously rotate, the cylinder is separated from the arc-shaped force-bearing rod, and the driving force of the cylinder on the arc-shaped force-bearing rod disappears. Under the elastic force of the elastic reset ring, the swing rod rotates in the reverse direction to reset. Thus, by the reciprocating swing of the swing rod, the alfalfa grass material falling into the receiving hopper can be shaken, making the material dispersed and not prone to material accumulation, further promoting the crushing of the alfalfa grass material, and making full use of the interaction between structures to connect the structures together.

[0017] Preferably, the arc-shaped force-bearing rod is installed obliquely, the swing rods are evenly distributed on the outer circumferential surface of the support rod, and the swing rods are installed obliquely.

[0018] Preferably, an auxiliary module is installed at the bottom of the inner cavity of the machine shell. The auxiliary module includes a material guiding plate. The top of the material guiding plate is hinged to the inner wall of the machine shell, and the material guiding plate is installed directly below the receiving hopper. The top end of the material guiding plate is fixedly connected with a connecting guide rod. The middle of the outer circumferential surface of the connecting guide rod is fixedly connected with an impact block. The top end of the connecting guide rod is fixedly connected with a circular pressure-receiving member. The bottom end of the material guiding plate is fixedly connected with an arc-shaped elastic strip. The connecting guide rod passes through the middle of the rectangular hole, and the circular pressure-receiving member is installed directly below the swing rod. When the swing rod rotates towards the position close to the bottom of the inner cavity of the receiving hopper, the swing rod exerts a downward pressing force on the circular pressure-receiving member. Then, the connecting guide rod can drive the material guiding plate to rotate towards the position close to the inner wall of the machine shell to adjust the angle, and the arc-shaped elastic strip is compressed. As the swing rod rotates in the reverse direction, the pressing force of the swing rod on the circular pressure-receiving member disappears. Under the elastic force of the arc-shaped elastic strip, the material guiding plate rotates in the reverse direction to reset. Thus, through the reciprocating swing of two symmetrical material guiding plates, which are always in a dynamic state, the discharge of the material leaking from the leakage hole can be promoted.

[0019] Preferably, the material guiding plate is installed obliquely. There are two material guiding plates, and the two material guiding plates are symmetrically installed along the central axis of the middle of the machine shell. The bottom end of the arc-shaped elastic strip is attached to the bottom of the inner cavity of the machine shell. When the material guiding plate rotates in the reverse direction to reset, the material guiding plate will drive the connecting guide rod to rotate in the reverse direction together, so that the impact block moves upward together with the connecting guide rod. The impact block will impact the bottom of the receiving hopper, making the receiving hopper vibrate, promoting the discharge of the crushed material from the leakage hole and not prone to blockage.

[0020] The present invention provides an alfalfa grass material crushing device with a pretreatment mechanism, having the following beneficial effects:

[0021] 1. The alfalfa material crushing equipment with a pretreatment mechanism can drive the rotating shaft to rotate by using the rotation of the output end of the servo motor, so that the cutting knife rotates with the rotating shaft. The alfalfa material is put into the interior of the barrel from the feed hopper. As the alfalfa material moves downward, the alfalfa material can be cut by the rotation of the cutting knife. Considering that the cutting knives are evenly distributed on the outer circumferential surface of the rotating shaft, the alfalfa material can be continuously cut, and the longer alfalfa material is cut into small segments, and it is not easy to get entangled.

[0022] 2. The alfalfa material crushing equipment with a pretreatment mechanism is supported by the conical shell. By using the rotating shaft to drive the conical shell to rotate, the material guiding rod will rotate with the conical shell. By using the rotation of the material guiding rod, the alfalfa material put in from the feed hopper can be stirred, promoting the alfalfa material to enter the interior of the barrel, which is convenient for subsequent pretreatment of the alfalfa material.

[0023] 3. As the material guiding rod stirs the alfalfa material, the alfalfa material enters the barrel and slides downward. Through the continuous rotation of the material guiding rod, when the bottom end of the material guiding rod contacts the surface of the arc-shaped convex block, the material guiding rod receives an upward oblique driving force, so that the material guiding rod slides into the interior of the conical shell, and the elastic sheet is compressed. Along with the contraction of the material guiding rod sliding into the interior of the conical shell, the alfalfa material remaining on the surface of the material guiding rod falls off.

[0024] 4. The alfalfa material crushing equipment with a pretreatment mechanism can drive the rotating roller to rotate by using the rotation of the output end of the power source, so that the rotary blade is driven to rotate in a circular motion, and the pretreated and cut alfalfa material can be crushed. By arranging the rotary blades and the triangular teeth in an alternating manner, the alfalfa material can be quickly crushed. The crushed alfalfa material leaks from the leakage holes, while the uncrushed alfalfa material remains to be further crushed, making the crushing of the alfalfa material uniform.

[0025] 5. When the arc-shaped force-bearing rod receives a driving force in the circumferential direction, the driving force can be applied to the support rod through the arc-shaped force-bearing rod, so that the swing rod rotates and adjusts the angle towards the bottom position close to the inner cavity of the material receiving hopper. As the driving force of the cylinder on the arc-shaped force-bearing rod disappears and under the elastic force of the elastic reset ring, the swing rod rotates in the reverse direction to reset. Thus, through the reciprocating swing of the swing rod, the alfalfa material falling into the material receiving hopper can be shaken, making the material dispersed and not easy to accumulate, further promoting the crushing of the alfalfa material, and making full use of the interaction between the structures to connect the structures together.

[0026] VI. For the alfalfa material crushing equipment with a pretreatment mechanism, by applying a downward pressing force on the circular pressure member with a swing rod, the guide plate can be driven by the connecting guide rod to rotate towards the position close to the inner wall of the machine shell to adjust the angle. As the pressing force of the swing rod on the circular pressure member disappears and under the elastic force of the arc-shaped elastic strip, the guide plate rotates in the reverse direction to reset. Through the reciprocating swing of the two symmetrical guide plates, which are always in a dynamic state, the discharging of the material leaking from the leakage holes can be promoted.

[0027] VII. For the alfalfa material crushing equipment with a pretreatment mechanism, when the guide plate rotates in the reverse direction to reset, the guide plate will drive the connecting guide rod to rotate in the reverse direction together, causing the impact block to move upward along with the connecting guide rod. The impact block will impact the bottom of the receiving hopper, enabling the receiving hopper to vibrate and promoting the crushed material to leak from the leakage holes, and it is not easy to cause blockage.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] The first embodiment is as Figures 1 to 4 shown, and the present invention provides a technical solution:

[0040] A lucerne material crushing device with a pretreatment mechanism, comprising:

[0041] A machine housing 1, and a power source 2 installed in the middle of the surface of the machine housing 1, and a cutting mechanism 3 is installed in the middle of the top of the machine housing 1;

[0042] The cutting mechanism 3 includes a barrel 31 and a servo motor 32. The barrel 31 is fixedly installed in the middle of the top of the machine housing 1, and the servo motor 32 is fixedly installed in the middle of the top of the barrel 31. A feeding hopper 33 is installed on the top surface of the barrel 31. A rotating shaft 34 is rotatably installed in the middle of the interior of the barrel 31. A material pushing component 35 is installed on the top outer circumference of the rotating shaft 34. A cutting knife 36 is fixedly connected to the middle outer circumference of the rotating shaft 34. The bottom end of the rotating shaft 34 is fixedly connected to a bent connecting rod 37. A cylinder 38 is rotatably installed at the bent part of the bottom of the bent connecting rod 37. The staff turns on the servo motor 32 to work. By using the rotation of the output end of the servo motor 32, the rotating shaft 34 can be driven to rotate, so that the cutting knife 36 rotates along with the rotating shaft 34, and the lucerne material is put into the interior of the barrel 31 from the feeding hopper 33. As the lucerne material moves downward, the lucerne material can be cut by the rotation of the cutting knife 36. And combined with the cutting knife 36 being evenly distributed on the outer circumference of the rotating shaft 34, the lucerne material can be continuously cut into small sections;

[0043] The cutting knives 36 are evenly distributed at the middle of the outer circumferential surface of the rotating shaft 34. There are two bent connecting rods 37, and the two bent connecting rods 37 are symmetrically installed along the rotating shaft 34. The bottom ends of the bent connecting rods 37 pass through the center of the cylinder 38.

[0044] The material feeding assembly 35 includes an arc-shaped convex block 351 and a conical shell 352. The bottom end of the arc-shaped convex block 351 is fixedly connected to the inner wall of the material cylinder 31. The center of the conical shell 352 is fixedly connected to the outer circumferential surface of the rotating shaft 34. A material feeding rod 353 is slidably installed at the conical surface of the conical shell 352. The arc-shaped convex block 351 and the material feeding rod 353 are installed at the same height. A resilient sheet 354 is fixedly connected between the top end of the material feeding rod 353 and the outer circumferential surface of the rotating shaft 34, and the resilient sheet 354 is installed inside the conical shell 352. Supported by the conical shell 352 and driven by the rotating shaft 34 to rotate, the material feeding rod 353 will rotate together with the conical shell 352. Then, by the rotation of the material feeding rod 353, the alfalfa grass material put in from the feed hopper 33 can be stirred to promote the alfalfa grass material to enter the interior of the material cylinder 31.

[0045] The rotating shaft 34 passes through the center of the conical shell 352. The bottom end of the material feeding rod 353 penetrates the inner wall of the conical shell 352 and extends to its outside. There are three material feeding rods 353, and the three material feeding rods 353 are evenly distributed on the surface of the conical shell 352.

[0046] As the material feeding rod 353 stirs the alfalfa grass material, the alfalfa grass material enters the material cylinder 31 and slides downward. And through the continuous rotation of the material feeding rod 353, by the contact between the bottom end of the material feeding rod 353 and the surface of the arc-shaped convex block 351, the material feeding rod 353 receives a pushing force obliquely upward, so that the material feeding rod 353 slides into the interior of the conical shell 352, and the resilient sheet 354 is compressed. Along with the contraction of the material feeding rod 353 sliding into the interior of the conical shell 352, the alfalfa grass material remaining on the surface of the material feeding rod 353 falls off.

[0047] Second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 7 as shown:

[0048] The material processing mechanism 4 is used to break the alfalfa grass material. The material processing mechanism 4 is installed at the middle of the inner cavity of the machine shell 1;

[0049] Among them, the material processing mechanism 4 includes a material receiving hopper 41 and a rotating roller 42. The material receiving hopper 41 is fixedly installed in the middle of the inner cavity of the machine housing 1, and the rotating roller 42 is rotatably installed in the middle of the top of the material receiving hopper 41. A material leakage hole 43 is opened at the middle of the bottom of the material receiving hopper 41. A triangular tooth 44 is fixedly connected to the bottom of the inner cavity of the material receiving hopper 41. A rotary blade 45 is fixedly connected to the outer circumferential surface of the rotating roller 42. A swing assembly 46 is installed at the top of the inner side surface of the material receiving hopper 41. The staff starts the power source 2 to work. By using the rotation of the output end of the power source 2, the rotating roller 42 can be driven to rotate, so that the rotary blade 45 is driven to rotate in a circle, and the alfalfa grass material after pretreatment cutting can be broken. And by arranging the rotary blade 45 and the triangular tooth 44 in an alternating manner, the alfalfa grass material can be quickly broken, and the broken alfalfa grass material leaks from the material leakage hole 43, while the unbroken alfalfa grass material is left to continue to be broken.

[0050] The rotating roller 42 is fixedly installed with the output end of the power source 2 through a coupling, and the material leakage hole 43 and the triangular tooth 44 are arranged in an alternating manner.

[0051] The rotary blade 45 is installed directly above the material leakage hole 43, and the rotary blade 45 is evenly distributed on the outer circumferential surface of the rotating roller 42. A cutting edge surface is opened at the edge of the surface of the triangular tooth 44.

[0052] The swing assembly 46 includes a rectangular hole 461 and a support rod 462. The rectangular hole 461 is opened at the side of the bottom of the material receiving hopper 41. The support rod 462 is rotatably installed at the top of the material receiving hopper 41. An arc-shaped force-bearing rod 463 is fixedly connected to the middle of the top of the outer circumferential surface of the support rod 462. A swing rod 464 is fixedly connected to the outer circumferential surface of the support rod 462. The swing rod 464 and the rotary blade 45 are arranged in an alternating manner. A resilient return ring 465 is fixedly connected between the bottom of the swing rod 464 and the bottom of the inner cavity of the material receiving hopper 41. By driving the rotating shaft 34 to rotate through the output end of the servo motor 32, the bent connecting rod 37 is driven to rotate together, and by using the contact between the cylinder 38 and the arc-shaped force-bearing rod 463, the arc-shaped force-bearing rod 463 receives a driving force in the circumferential direction, so that the driving force can be applied to the support rod 462 through the arc-shaped force-bearing rod 463, thereby enabling the swing rod 464 to rotate and adjust the angle towards the position close to the bottom of the inner cavity of the material receiving hopper 41, and the resilient return ring 465 is compressed. As the rotating shaft 34 drives the bent connecting rod 37 to continuously rotate, the cylinder 38 is separated from the arc-shaped force-bearing rod 463, and the driving force of the cylinder 38 on the arc-shaped force-bearing rod 463 disappears. Under the elastic force of the resilient return ring 465, the swing rod 464 rotates in the reverse direction to reset. Thus, by the reciprocating swing of the swing rod 464, the alfalfa grass material falling into the material receiving hopper 41 can be shaken, so that the material is dispersed.

[0053] The arc-shaped force-bearing rod 463 is installed obliquely, the swing rods 464 are evenly distributed on the outer circumferential surface of the support rod 462, and the swing rods 464 are installed obliquely.

[0054] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 9 as shown:

[0055] An auxiliary module 5 is installed at the bottom of the inner cavity of the machine case 1. The auxiliary module 5 includes a material guiding plate 51. The top of the material guiding plate 51 is hinged between the inner wall of the machine case 1, and the material guiding plate 51 is installed directly below the material receiving hopper 41. A connecting guide rod 52 is fixedly connected to the top end of the material guiding plate 51. An impact block 53 is fixedly connected to the middle of the outer circumferential surface of the connecting guide rod 52. A circular pressure-receiving member 54 is fixedly connected to the top end of the connecting guide rod 52. An arc-shaped elastic strip 55 is fixedly connected to the bottom end of the material guiding plate 51. The connecting guide rod 52 passes through the middle of the rectangular hole 461, and the circular pressure-receiving member 54 is installed directly below the swing rod 464. When the swing rod 464 rotates towards the position close to the bottom of the inner cavity of the material receiving hopper 41, the swing rod 464 exerts a downward pressing force on the circular pressure-receiving member 54, and then the material guiding plate 51 can be driven to rotate towards the position close to the inner wall of the machine case 1 through the connecting guide rod 52 to adjust the angle, and the arc-shaped elastic strip 55 is compressed. As the swing rod 464 rotates in the reverse direction, the pressing force of the swing rod 464 on the circular pressure-receiving member 54 disappears, and under the elastic force of the arc-shaped elastic strip 55, the material guiding plate 51 rotates in the reverse direction to reset. Through the reciprocating swing of the two symmetrical material guiding plates 51, which are always in a dynamic state, the discharge of the material leaking from the leakage hole 43 can be promoted.

[0056] The material guiding plate 51 is installed obliquely. There are two material guiding plates 51, and the two material guiding plates 51 are symmetrically installed along the central axis in the middle of the machine case 1. The bottom end of the arc-shaped elastic strip 55 is attached to the bottom of the inner cavity of the machine case 1. When the material guiding plate 51 rotates in the reverse direction to reset, the material guiding plate 51 will drive the connecting guide rod 52 to rotate in the reverse direction together, so that the impact block 53 moves upward together with the connecting guide rod 52, and the impact block 53 will impact the bottom of the material receiving hopper 41, so that the material receiving hopper 41 generates vibration, promoting the broken material to leak from the leakage hole 43 and not easily getting blocked.

[0057] During use, first put the alfalfa raw material to be broken from the feed hopper 33, and the staff starts the servo motor 32 to work. By using the rotation of the output end of the servo motor 32, the rotating shaft 34 can be driven to rotate, so that the cutting knife 36 rotates together with the rotating shaft 34, and the alfalfa material is put into the inside of the material cylinder 31 from the feed hopper 33;

[0058] Moreover, the conical shell 352 is driven to rotate by the rotating shaft 34. The material shifting rod 353 will rotate along with the conical shell 352. By using the rotation of the material shifting rod 353, the alfalfa grass material put in from the feed hopper 33 can be shifted, promoting the alfalfa grass material to enter the interior of the barrel 31;

[0059] As the material shifting rod 353 shifts the alfalfa grass material, the alfalfa grass material enters the barrel 31 and slides downward. And through the continuous rotation of the material shifting rod 353, by using the contact between the bottom end of the material shifting rod 353 and the surface of the arc-shaped convex block 351, the material shifting rod 353 receives an upward oblique driving force, so that the material shifting rod 353 slides into the interior of the conical shell 352, and the elastic piece 354 is compressed. Along with the contraction of the material shifting rod 353 as it slides into the interior of the conical shell 352, the alfalfa grass material remaining on the surface of the material shifting rod 353 falls off;

[0060] And by using the downward movement of the alfalfa grass material, the alfalfa grass material can be cut by the rotation of the cutting knife 36. And considering that the cutting knives 36 are evenly distributed on the outer circular surface of the rotating shaft 34, the alfalfa grass material can be continuously cut into small segments;

[0061] Moreover, the rotating shaft 34 is driven to rotate by the output end of the servo motor 32, so that the bending connecting rod 37 is driven to rotate together. By using the contact between the cylinder 38 and the arc-shaped force-bearing rod 463, the arc-shaped force-bearing rod 463 receives a driving force in the circumferential direction. Then, the driving force can be applied to the support rod 462 through the arc-shaped force-bearing rod 463, so that the swing rod 464 rotates and adjusts its angle towards the bottom position close to the inner cavity of the receiving hopper 41, and the elastic reset ring 465 is compressed. As the rotating shaft 34 drives the bending connecting rod 37 to continuously rotate, the cylinder 38 is separated from the arc-shaped force-bearing rod 463, and the driving force of the cylinder 38 on the arc-shaped force-bearing rod 463 disappears. Under the elastic force of the elastic reset ring 465, the swing rod 464 rotates in the reverse direction for resetting. Thus, through the reciprocating swing of the swing rod 464, the alfalfa grass material falling into the receiving hopper 41 can be shaken, making the material dispersed;

[0062] Meanwhile, the staff starts the power source 2 to work. By using the rotation of the output end of the power source 2, the rotating roller 42 can be driven to rotate, so that the rotary blade 45 is driven to rotate in a circle, and the pre-treated and cut alfalfa grass material can be broken. And by using the staggered arrangement of the rotary blade 45 and the triangular teeth 44, the alfalfa grass material can be quickly broken. The broken alfalfa grass material leaks from the leakage holes 43, while the unbroken alfalfa grass material remains to be broken continuously;

[0063] Moreover, the connecting guide rod 52 passes through the middle of the rectangular hole 461, and the circular pressure-receiving member 54 is installed directly below the swing rod 464. When the swing rod 464 rotates towards the position close to the bottom of the inner cavity of the material receiving hopper 41, the swing rod 464 applies a downward pressing force on the circular pressure-receiving member 54. Then, the guide plate 51 can be driven by the connecting guide rod 52 to rotate towards the position close to the inner wall of the machine housing 1 to adjust the angle. The arc-shaped elastic strip 55 is compressed. As the swing rod 464 rotates in the reverse direction, the pressing force of the swing rod 464 on the circular pressure-receiving member 54 disappears. Under the elastic force of the arc-shaped elastic strip 55, the guide plate 51 rotates in the reverse direction to reset. By reciprocating the swing of the two symmetrical guide plates 51, which are always in a dynamic state, the discharging of the materials leaking from the material leakage hole 43 can be promoted.

[0064] When the guide plate 51 rotates in the reverse direction to reset, the guide plate 51 will drive the connecting guide rod 52 to rotate in the reverse direction together, so that the impact block 53 moves upward together with the connecting guide rod 52. The impact block 53 will impact the bottom of the material receiving hopper 41, so that the material receiving hopper 41 can generate vibration, promoting the broken materials to leak from the material leakage hole 43 and preventing blockage.
