Description

Technical Field

[0001] This invention relates to the field of feed processing equipment technology, specifically to a fermented total mixed feed processing device and preparation method for cattle and sheep. Background Technology

[0002] In the processing of fermented total mixed feed for cattle and sheep, ensuring the uniform mixing of all feed components is crucial. Currently, the mixing of this type of feed typically involves two key stages: first, the initial mixing of roughage and concentrate, followed by a secondary mixing of additive powders into the initially mixed feed.

[0003] Reference Figure 11 After the feed is mixed, it is directly packaged into individual feed balls by a baler, making it convenient for livestock farms to use directly and solving the feed supply problem for some small livestock farms to a certain extent.

[0004] However, traditional methods of applying additive powders have significant drawbacks. They employ a point-to-point or line-to-line application method, resulting in low efficiency. This leads to prolonged mixing of the feed while waiting for the powder to distribute evenly, easily resulting in over-mixing. Over-mixing not only wastes energy but can also damage the physical properties and nutritional components of the feed, affecting its quality.

[0005] Moreover, this single-point powdering method makes it difficult to ensure that the powder is dispersed quickly and evenly in the feed, thus affecting the quality stability and nutritional balance of the final product. In order to improve the processing quality and efficiency of fermented total mixed feed for cattle and sheep, it is urgent to improve the existing powdering method and develop more efficient and reasonable mixing processes and equipment. Summary of the Invention

[0006] Therefore, it is necessary to provide a processing device and preparation method for fermented total mixed feed for cattle and sheep, addressing the existing technical problems.

[0007] To solve the problems of existing technologies, the technical solution adopted by the present invention is as follows: a fermented total mixed feed processing device for cattle and sheep, comprising a frame, a U-shaped mixing drum fixedly mounted on the frame, a stirring shaft rotatably mounted inside the U-shaped mixing drum, and several stirring paddles arranged at equal intervals along the axis of the stirring shaft. It also includes a spreading mechanism, a spreading mechanism, a driving mechanism, and a switching mechanism. The U-shaped mixing drum lies horizontally on the frame with its U-shaped opening facing upwards. A top cover is hinged to the opening of the U-shaped mixing drum. One end of the U-shaped mixing drum has a feeding port, and the other end has a discharge port. A storage frame is located below the discharge port. The spreading mechanism is located below the top cover and includes a sprayer slidably mounted along the length of the U-shaped mixing drum and a moving output end that drives the sprayer to reciprocate. The spreading mechanism is configured with... Below the material spreading mechanism, the material spreading mechanism includes a corrugated baffle fixedly installed on the inner wall of the U-shaped mixing cylinder and a vibrating output end for spreading material through the gaps between the corrugated baffle. Each trough of the corrugated baffle is provided with a number of sieve holes at equal intervals along its length. The driving mechanism is located at one end of the U-shaped mixing cylinder near the feeding port. The driving mechanism includes a rotating output end for driving the stirring shaft to rotate. The switching mechanism is located on the outer wall of the U-shaped mixing cylinder. The switching mechanism includes a first cutting-off output end and a second cutting-off output end. The rotating output end is connected to the moving output end of the material spreading mechanism through the first cutting-off output end. The stirring shaft is connected to the vibrating output end of the material spreading mechanism through the second cutting-off output end. The first cutting-off output end and the second cutting-off output end are mutually exclusive.

[0008] Furthermore, the spreading mechanism also includes a bearing plate set at the top of the U-shaped mixing cylinder and limiting rods and reciprocating screws symmetrically set on both sides of the top of the U-shaped mixing cylinder. The reciprocating screw and the limiting rods are both connected to the U-shaped mixing cylinder through shaft seats. One end of the bearing plate is slidably connected to the limiting rod, and the other end is threadedly connected to the reciprocating screw. The sprayer is fixedly set on the bearing plate.

[0011] Furthermore, the material spreading mechanism also includes a baffle grid located below the corrugated partition and a connecting horizontal plate fixedly located at one end of the baffle grid. The baffle grid is elastically connected to the side wall of the U-shaped mixing cylinder. Several baffle plates are evenly spaced along the width direction on the baffle grid. The number of baffle rods is consistent with the number of troughs of the corrugated partition and corresponds one-to-one.

The touch plate is the vibration output end of the material spreading mechanism, and the second chuck is the second cutting end output end of the switching mechanism.

[0013] Furthermore, the spraying mechanism also includes a drive gear ring coaxially fixed at one end of the stirring shaft near the drive sprocket, a support bracket set above the drive gear ring and fixed to the U-shaped mixing cylinder, a transmission shaft rotatably set on the support bracket, and a driven gear coaxially fixed on the transmission shaft. The drive gear ring meshes with the driven gear, and the transmission shaft is keyed to the drive sprocket.

[0014] Furthermore, the U-shaped mixing drum has several through holes spaced at equal intervals at its arc-shaped bottom. An arc-shaped air box is fixedly installed on the arc-shaped bottom of the U-shaped mixing drum, communicating with the interior of the through holes. A mounting plate is fixedly installed at one end of the frame near the discharge port. A limiting vertical plate is fixedly installed on the mounting plate, and a drive shaft is rotatably mounted on the limiting vertical plate.

An air cylinder is used to pump air into the transfer box.

[0015] Furthermore, several sets of vent holes are evenly spaced along the axis of the stirring shaft, and each set of vent holes is evenly spaced along the circumference of the stirring shaft.

A transfer air box is fixedly installed on the mounting plate, and the transfer air box is connected to the transfer box through a hose. The end of the inner tube near the transfer air box is rotatably connected to the transfer air box.

[0016] A method for preparing fermented total mixed feed for cattle and sheep includes the following steps:

[0017] S1: Put roughage and concentrate into the feed inlet, open the cover, and put an appropriate amount of additive powder into the sprayer;

[0018] S2: The rotating output end drives the mixing shaft to rotate, and the two feeds are initially mixed by the mixing paddle. At the same time, the rotating output end drives the moving output end of the spreading mechanism through the first cutting output end, thereby causing the sprayer to move back and forth.

[0019] S3: The sprayer moves back and forth to evenly pre-spread the additive powder onto the corrugated baffle, and the additive powder is temporarily piled up in the troughs of the corrugations.

[0020] S4: After the concentrate and roughage are mixed, the additive powder added to the sprayer is also pre-spread onto the corrugated partition. The first cut-off output end of the switching mechanism cuts off the connection between the rotary output end and the moving output end, causing the sprayer to stop moving. At the same time, the second cut-off output end establishes a connection between the mixing shaft and the vibration output end.

[0021] S5: The operation of the vibration output end causes the additive powder pre-laid in the trough of the corrugated baffle to be intermittently shaken off from the sieve holes.

[0022] S6: After the additive powder is mixed, the feed is discharged from the discharge port and the equipment resets.

[0023] The beneficial effects of this invention compared to the prior art are:

[0024] Firstly, it efficiently mixes feed powder. Compared to traditional powder addition methods that involve point-to-point spreading, this device uses a sprayer to pre-lay the powder on a corrugated partition, and then intermittently spreads it over a surface. This innovative method allows the additive powder to be more evenly and quickly integrated into the feed, shortening the mixing time, improving mixing efficiency, and resulting in a more balanced nutrient distribution in cattle and sheep feed.

[0025] Secondly, it prevents powder from settling and clumping. The device blows air through the bottom holes of the U-shaped mixing cylinder and the air vents of the stirring shaft to prevent powder from settling and feed from clumping. During the mixing of additive powder, intermittent air blowing from the bottom prevents powder from accumulating at the bottom, and the air vents of the stirring shaft work in conjunction with the air blowing to break up any clumps that may form, ensuring that the feed is mixed evenly and improving product quality.

[0026] Thirdly, automated processes and precise switching: the drive mechanism and switching mechanism work together to achieve automated connection of each process. From mixing roughage and concentrate to pre-spreading powder, and then to mixing powder, the switching mechanism precisely controls each motion output end. The first and second cutting-off output ends operate mutually exclusively, ensuring that each stage of work proceeds in an orderly manner, reducing manual intervention, and improving processing efficiency and stability.

Detailed Implementation

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] refer to Figures 1 to 11 :

[0041] A fermented total mixed feed processing device for cattle and sheep includes a frame 1, a U-shaped mixing cylinder 2 fixedly mounted on the frame 1, a stirring shaft 32 rotatably mounted inside the U-shaped mixing cylinder 2, and several stirring paddles 36 arranged sequentially and at equal intervals along the axis of the stirring shaft 32. It also includes a spreading mechanism, a spreading mechanism, a driving mechanism, and a switching mechanism. The U-shaped mixing cylinder 2 lies horizontally on the frame 1 with its U-shaped opening facing upwards. A top cover 3 is hinged to the opening of the U-shaped mixing cylinder 2. One end of the U-shaped mixing cylinder 2 has a feeding port 18, and the other end has a discharge port 19. A storage frame 22 is located below the discharge port 19. The spreading mechanism is located below the top cover 3 and includes a sprayer 13 slidably mounted along the length of the U-shaped mixing cylinder 2 and a moving output end that drives the sprayer 13 to reciprocate. The spreading mechanism is located below the spreading mechanism and includes components fixedly mounted on the U-shaped mixing cylinder 2. The U-shaped mixing cylinder 2 has a corrugated baffle 4 on its inner wall and a vibrating output end for driving the corrugated baffle 4 to spread material at intervals. The corrugated baffle 4 divides the U-shaped mixing cylinder 2 into two chambers, the upper one being the material spreading chamber and the lower one being the mixing chamber. Each trough of the corrugated baffle 4 is provided with a number of sieve holes 5 at equal intervals along its length. The driving mechanism is located at one end of the U-shaped mixing cylinder 2 near the feeding port 18. The driving mechanism includes a rotating output end, which is used to drive the stirring shaft 32 to rotate. The switching mechanism is located on the outer wall of the U-shaped mixing cylinder 2. The switching mechanism includes a first cutting output end and a second cutting output end. The rotating output end is connected to the moving output end of the material spreading mechanism through the first cutting output end. The stirring shaft 32 is connected to the vibrating output end of the spreading mechanism through the second cutting output end. The first cutting output end and the second cutting output end are mutually exclusive.

[0042] It should be noted that when the rotary output end is connected to the moving output end of the spreading mechanism through the first cutting output end, the second cutting output end disconnects the connection between the stirring shaft 32 and the vibration output end.

[0043] It should also be noted that the roughage mentioned in this article can be made from the following raw materials: high-quality forage such as alfalfa, silage corn, and locally sourced agricultural by-products (apple fry, Chinese medicine residue, tomato pomace); concentrate can be made from the following raw materials: corn, soybean meal, cottonseed meal, etc.; and additive powder can be made from the following raw materials: Lactobacillus brucelli and Lactobacillus plantarum, with an addition amount of 1×10⁻⁶. 5 cfu / g; The above raw materials are used to adjust the ratio to produce feed as needed. Geographical agricultural by-products generated in agricultural production can be used in the breeding process through fermentation of total mixed rations to save costs. In the process of preparing fermented total mixed rations, inoculation with Lactobacillus plantarum helps to promote fermentation and reduce dry matter loss, while inoculation with Lactobacillus buchneri only helps to prolong its aerobic stability.

[0044] When the device is running, roughage and concentrate are fed into the feed inlet 18, the cover is opened, and an appropriate amount of additive powder is added into the spreader 13. Then, the rotating output end drives the stirring shaft 32 to rotate, and the two feeds are initially mixed by the stirring paddle. At the same time, the rotating output end drives the moving output end of the spreading mechanism through the first cutting output end, so that the spreader 13 moves back and forth to evenly pre-spread the additive powder onto the corrugated baffle 4. The additive powder temporarily accumulates in the troughs. After the concentrate and roughage are mixed, the additive powder added into the spreader 13 is also pre-spread onto the corrugated baffle 4. The first cutting output end of the switching mechanism cuts off the connection between the rotating output end and the moving output end, causing the spreader 13 to stop moving. At the same time, the second cutting output end connects the stirring shaft 32 to the vibrating output end. The operation of the vibrating output end causes the additive powder pre-spread in the troughs of the corrugated baffle 4 to fall intermittently from the sieve holes 5. After the additive powder is mixed, the feed is discharged from the discharge port 19, and the equipment is reset.

[0045] To demonstrate the detailed structure of the material spreading mechanism and the drive mechanism, the following features are specifically included:

[0046] The material spreading mechanism also includes a bearing plate 12 set on the top of the U-shaped mixing cylinder 2, a limiting rod 10 symmetrically set on both sides of the top of the U-shaped mixing cylinder 2, and a reciprocating screw 11. The reciprocating screw 11 and the limiting rod 10 are both connected to the U-shaped mixing cylinder 2 through a bearing seat. One end of the bearing plate 12 is slidably connected to the limiting rod 10, and the other end is threadedly connected to the reciprocating screw 11. The sprayer 13 is fixedly set on the bearing plate 12. The driving mechanism includes a drive motor 20 fixedly set on the frame 1 and a connecting shaft 21 coaxially fixedly connected to the output shaft of the drive motor 20. The connecting shaft 21 is coaxially fixedly connected to the stirring shaft 32. The reciprocating screw 11 is connected to the connecting shaft 21 through the first cutting output end.

[0047] The reciprocating lead screw 11 is the moving output end of the material spreading mechanism, and the connecting shaft 21 is the rotating output end of the drive mechanism.

[0048] When the device is running, the drive motor 20 drives the connecting shaft 21 to rotate, the connecting shaft 21 rotates and drives the stirring shaft 32 to rotate, the connecting shaft 21 rotates and drives the reciprocating screw 11 to rotate through the first cutting output end, the reciprocating screw 11 rotates and causes the bearing plate 12 to move back and forth along the axis of the reciprocating screw 11. At the same time, the setting of the limit rod 10 can make the reciprocating movement of the bearing plate 12 more stable. The reciprocating movement of the bearing plate 12 then drives the sprayer 13 to move back and forth, so that when the roughage and concentrate are mixed, the additive powder is pre-spread on the corrugated partition 4 in advance.

[0049] To demonstrate the detailed structure of the switching mechanism, the following features were also included:

[0050] The switching mechanism includes a push rod 38 fixedly mounted on the outer wall of the U-shaped mixing drum 2, a transmission horizontal plate 39 slidably mounted on the outer wall of the U-shaped mixing drum 2, a transition horizontal plate 40 fixedly mounted on one end of the transmission horizontal plate 39, a drive pulley 41 and a drive sprocket 45 rotatably mounted on the transition horizontal plate 40, a first chuck 43 coaxially fixedly connected to the driven pulley 42, a first sleeve 14 elastically keyed to the end of the reciprocating screw 11 near the first chuck 43, and a first connecting plate 15 coaxially fixedly connected to the first sleeve 14. The drive pulley 41 is keyedly connected to the connecting shaft 21, and the driven pulley 42 is connected to the drive pulley 41 by a belt. The output end of the push rod 38 is fixedly connected to the transmission horizontal plate 39, and the first chuck 43 is the first cut-off output end of the switching mechanism.

[0051] It should be noted that when roughage and concentrate are mixed, the push rod 38 moves, driving the transmission plate 39 to move. The transmission plate 39 moves, driving the adapter plate 40 to move. The adapter plate 40 moves, causing the first chuck 43 to press against the first connecting plate 15. Then, the rotation of the connecting shaft 21 drives the drive pulley 41 to rotate. The drive pulley 41 rotates, driving the driven pulley 42 to rotate. The driven pulley 42 rotates, driving the first chuck 43 to rotate. The first chuck 43 rotates, driving the first connecting plate 15 to rotate. The first connecting plate 15 rotates, driving the first sleeve 14 to rotate. The first sleeve 14 rotates, driving the reciprocating screw 11 to rotate.

[0052] To demonstrate the detailed structure of the material spreading mechanism, the following features were also included:

[0053] The material spreading mechanism also includes a baffle grid 6 located below the corrugated partition 4 and a connecting horizontal plate 8 fixedly located at one end of the baffle grid 6. The baffle grid 6 is elastically connected to the side wall of the U-shaped mixing cylinder 2. Several baffle plates 7 are evenly spaced along the width direction on the baffle grid 6. The number of baffle rods is consistent with the number of troughs of the corrugated partition 4 and corresponds one-to-one. The baffle rods are used to block the screen holes 5 at the troughs of the corrugated partition 4. The connecting horizontal plate 8 is connected to the vibration output end for transmission.

[0054] It should be noted that, in the initial state, the baffle rod blocks the screen hole 5. When the device is running, the vibration output end drives the connecting horizontal plate 8 to vibrate back and forth. The vibrating of the connecting horizontal plate 8 drives the baffle grid 6 to vibrate back and forth. The vibrating of the baffle grid 6 in turn drives the baffle plate 7 to intermittently block the screen hole 5, thereby realizing the intermittent falling of the additive powder, thus ensuring that the additive powder falls into the U-shaped mixing cylinder 2 "in a surface manner", shortening the mixing time and improving the mixing degree.

[0055] To demonstrate the detailed structure of the vibration output end, the following features were specifically included:

[0056] The feeding mechanism also includes a limiting bracket 23 fixedly installed below the connecting horizontal plate 8 and fixedly connected to the U-shaped mixing cylinder 2, a bearing shaft 24 rotatably installed on the limiting bracket 23, a second sleeve 25 elastically connected to the bearing shaft 24, a second connecting plate 26 coaxially fixedly connected to the second sleeve 25, a trigger plate 27 coaxially fixedly installed at the end of the bearing shaft 24 away from the second sleeve 25, a plurality of actuating teeth 28 arranged in a ring on the trigger plate 27, and a triggering protrusion 9 fixedly installed in the middle of the connecting horizontal plate 8. The switching mechanism also includes a transmission mechanism fixedly installed on the transmission plate 23. The mounting plate 44 is located at the end of the horizontal plate 39 away from the connecting horizontal plate 40. A first driven sprocket 46 is rotatably mounted on the top of the mounting plate 44. A driving sprocket 45 is located below the first driven sprocket 46 and rotatably connected to the mounting plate 44. A second chuck 47 is coaxially fixed on the first driven sprocket 46. The driving sprocket 45 is connected to the stirring shaft 32. The driving sprocket 45 is connected to the first driven sprocket 46 by a chain. The touch plate 27 is the vibration output end of the spreading mechanism. The second chuck 47 is the second cutting end output end of the switching mechanism.

[0057] After the concentrate and roughage are mixed, the push rod 38 moves, driving the transmission plate 39 to move. The transmission plate 39 first drives the transfer plate 40 to move, causing the first chuck 43 to separate from the first connecting plate 15. At the same time, the movement of the transmission plate 39 drives the mounting plate 44 to move closer to the U-shaped mixing cylinder 2, thereby driving the second chuck 47 to move closer to the second connecting plate 26. Then, the rotation of the stirring shaft 32 is transmitted to the drive sprocket 45, which drives the first driven sprocket 46 to rotate. The rotation of the first driven sprocket 46 drives the second chuck 47 to rotate, which drives the second connecting plate 26 to rotate. The rotation of the second connecting plate 26 drives the second sleeve 25 to rotate, which drives the bearing shaft 24 to rotate. The rotation of the bearing shaft 24 drives the touch plate 27 to rotate, which in turn drives several actuating teeth 28 to rotate, causing the actuating teeth 28 to reciprocate and contact the touch protrusion 9, thus causing the connecting plate 8 to reciprocate and vibrate.

[0058] To demonstrate how the stirring shaft 32 is connected to the drive sprocket 45, the following features are specifically included:

[0059] The sprayer 13 also includes a drive gear ring 37 coaxially fixed at one end of the mixing shaft 32 near the drive sprocket 45, a support bracket 29 fixed above the drive gear ring 37 and connected to the U-shaped mixing cylinder 2, a transmission shaft 30 rotatably mounted on the support bracket, and a driven gear 31 coaxially fixed on the transmission shaft 30. The drive gear ring 37 meshes with the driven gear 31, and the transmission shaft 30 is keyed to the drive sprocket 45.

[0060] When the second chuck 47 and the second connecting disc 26 are engaged together, the rotation of the stirring shaft 32 drives the rotation of the driving gear ring 37, the rotation of the driving gear ring 37 drives the rotation of the driven gear 31, the rotation of the driven gear 31 drives the rotation of the transmission shaft 30, and the rotation of the transmission shaft 30 drives the rotation of the driving sprocket 45.

[0061] To prevent powder from settling to the bottom of the U-shaped mixing cylinder 2 after it is added, the following features are specifically designed:

[0062] The U-shaped mixing cylinder 2 has several through holes 16 at equal intervals at its arc-shaped bottom. An arc-shaped air box 17 is fixedly installed on the arc-shaped bottom of the U-shaped mixing cylinder 2, and the arc-shaped air box 17 communicates with the interior of the through holes 16. A mounting plate 51 is fixedly installed at one end of the frame 1 near the discharge port 19. A limiting vertical plate 52 is fixedly installed on the mounting plate 51. A drive shaft 53 is rotatably installed on the limiting vertical plate 52. A transfer box 58 is fixedly installed next to the limiting vertical plate 52. An air cylinder 60 is installed on the side wall of the transfer box 58. A push rod 59 is fixedly installed on the air cylinder 60 and is slidably connected to the transfer box 58. One end of the drive shaft 53 is coaxially fixedly connected to a lever. A connecting rod 57 is eccentrically connected to a rotating disc 56. The end of the connecting rod 57 away from the rotating disc 56 is hinged to a top rod 59. A second driven sprocket 48 is rotatably mounted at the bottom of a mounting plate 44. A third chuck 49 is coaxially fixed on the second driven sprocket 48. A third sleeve 54 is elastically connected to the end of a drive shaft 53 away from the rotating disc 56. A third connecting plate 55 is coaxially fixed on the third sleeve 54. The second driven sprocket 48 and the first driven sprocket 46 are connected to the drive sprocket 45 via a chain. The transfer box 58 is connected to the inside of the arc-shaped air box 17 via a hose. An air cylinder 60 is used to pump air into the transfer box 58.

[0063] It should be noted that a one-way valve is installed at through hole 16. Simultaneously, the second chuck 47 engages with the second connecting disc 26, and the third chuck 49 engages with the third connecting disc 55. Then, the rotation of the drive sprocket 45 simultaneously drives the second driven sprocket 48 to rotate. The rotation of the second driven sprocket 48 drives the third chuck 49 to rotate, which in turn drives the third connecting disc 55 to rotate. The rotation of the third connecting disc 55 drives the third sleeve 54 to rotate, which in turn drives the drive shaft 53 to rotate. The rotation of shaft 53 drives the rotation of the actuating disc 56, which in turn drives the connecting rod 57 to rotate. The rotation of the connecting rod 57 causes the top rod 59 to reciprocate and compress the air cylinder 60. The air cylinder 60 then continuously pumps air into the transfer box 58. The gas then enters the arc-shaped air box 17 through the hose. The gas is then intermittently blown out from the through hole 16 at the bottom of the U-shaped mixing cylinder 2. Thus, during the mixing of additive powder, the bottom plate of the U-shaped mixing cylinder 2 will intermittently blow air to prevent powder from settling to the bottom, ensuring uniform mixing and improving the mixing quality.

[0064] To further ensure that the feed mixes evenly and does not clump after being added as powder, the following features are specifically included:

[0065] Several sets of vent holes 33 are evenly spaced along the axis of the stirring shaft 32. Each set of vent holes 33 is evenly spaced along the circumference of the stirring shaft 32. An inner tube 34 is coaxially and elastically connected inside the stirring shaft 32. Several sets of air supply holes 35 are evenly spaced along the axis of the inner tube 34. An adapter air box 50 is fixedly installed on the mounting plate 44. The adapter air box 50 is connected to the transfer box 58 through a hose. The end of the inner tube 34 near the adapter air box 50 is rotatably connected to the adapter air box 50.

[0066] It should be noted that when roughage and concentrate are mixed, the vent 33 and the air delivery vent 35 are staggered. When the mounting plate 44 drives the second chuck 47 to engage with the second connecting plate 26, the mounting plate 44 also drives the transfer air box 50 to move. The movement of the transfer air box 50 drives the inner tube 34 to move along the axis of the stirring shaft 32, causing the vent 33 and the air delivery vent 35 to coincide. Then, the gas enters the transfer air box 50 from the transfer box 58 through the hose, and then is blown out through the air delivery vent 35 and the vent 33 in sequence. Finally, the gas is blown out through the through hole 16 at the bottom of the U-shaped mixing cylinder 2 and the vent 33 on the stirring shaft 32. While stirring and mixing, the feed is also blown to prevent the feed from clumping and ensure that the feed is mixed evenly.

[0067] A method for preparing fermented total mixed feed for cattle and sheep includes the following steps:

[0068] S1: Feed roughage and concentrate into feed through feed inlet 18, open the cover, and feed an appropriate amount of additive powder into sprayer 13.

[0069] S2: The rotating output end drives the stirring shaft 32 to rotate, and the two feeds are initially mixed by the stirring paddle. At the same time, the rotating output end drives the moving output end of the spreading mechanism through the first cutting output end, thereby causing the sprayer 13 to move back and forth.

[0070] S3: The sprayer 13 moves back and forth to evenly pre-spread the additive powder onto the corrugated baffle 4, and the additive powder is temporarily piled up at the trough of the wave.

[0071] S4: After the concentrate and roughage are mixed, the additive powder added to the sprayer 13 is also pre-spread onto the corrugated baffle 4. The first cut-off output end of the switching mechanism cuts off the connection between the rotary output end and the moving output end, causing the sprayer 13 to stop moving. At the same time, the second cut-off output end establishes a connection between the mixing shaft 32 and the vibration output end.

[0072] S5: The operation of the vibration output end causes the additive powder pre-laid in the trough of the corrugated baffle 4 to be intermittently shaken off from the sieve hole 5.

[0073] S6: After the additive powder is mixed, the feed is discharged from the discharge port 19, and the equipment resets.

[0074] The working principle of this device is as follows: First, feed roughage and concentrate are fed into the feed inlet 18. Then, additive powder is placed in the sprayer 13 and the top cover 3 is opened. The drive motor 20 drives the connecting shaft 21 to rotate. The connecting shaft 21 drives the stirring shaft 32 to rotate, and the roughage and concentrate are initially mixed by the stirring paddle. On the other hand, the connecting shaft 21 drives the reciprocating screw 11 to rotate through the first cutting output end of the switching mechanism, so that the bearing plate 12 moves smoothly back and forth along the limit rod 10, and drives the sprayer 13 to evenly pre-spread the additive powder on the corrugated partition 4.

[0075] After the roughage and concentrate feed are mixed, the switching mechanism operates. Push rod 38 pushes transmission plate 39, causing the first chuck 43 to separate from the first connecting plate 15, while the second chuck 47 approaches and engages with the second connecting plate 26. The rotation of stirring shaft 32 is transmitted to drive sprocket 45 through drive gear ring 37, driven gear 31, and transmission shaft 30, driving the first driven sprocket 46 and the second chuck 47 to rotate, which in turn causes the touch plate 27 to rotate. Through the actuating teeth 28, the touch protrusion 9 is contacted, causing the connecting plate 8 and the baffle grid 6 to vibrate back and forth, so that the additive powder is intermittently shaken off from the sieve holes 5.

[0076] Simultaneously, the movement of the transmission plate 39 engages the third chuck 49 with the third connecting plate 55. The drive sprocket 45 drives the second driven sprocket 48, causing the drive shaft 53 to rotate. This, through the actuating disc 56 and connecting rod 57, drives the top rod 59 to compress the air cylinder 60. The gas passes through the transfer box 58 and hose into the arc-shaped air box 17, and is blown out from the bottom through-hole 16 of the U-shaped mixing cylinder, preventing the powder from settling. Furthermore, the mounting plate 44 drives the transfer air box 50 to move, aligning the vent 33 in the mixing shaft 32 with the air delivery hole 35 in the inner tube 34. Gas is blown out from the vent 33, working in conjunction with bottom blowing to prevent feed from clumping and ensure uniform mixing. Finally, the mixed feed is discharged from the discharge port 19, and the equipment resets.

[0077] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
