Technical Field

[0001] This utility model relates to the field of feed production technology, and in particular to a straw puffing system. Background Technology

[0002] The livestock industry is developing rapidly, with high demand and high costs, making the development of unconventional feeds an urgent matter.

[0003] Straw puffing and bio-fermentation (micro-storage) feed preparation technology is a simple, reliable, economical, and practical roughage microbial treatment technology. It involves adding one or more beneficial microbial agents to roughage such as straw in a specific ratio, and then, under sealed and suitable conditions, allowing the beneficial microorganisms to multiply and ferment, transforming coarse or dry yellow straw and forage into soft, juicy, fragrant, palatable, and highly usable roughage.

[0004] However, the efficiency of existing straw puffing equipment has not been fully developed, so there is a need to design a high-efficiency straw puffing equipment. Utility Model Content

[0005] In view of this, the present invention provides a straw puffing system, the main purpose of which is to standardize the straw puffing process and improve the efficiency of puffing.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0008] The first mixer is connected to the water inlet tank, and the second mixer is connected to the bacterial culture tank.

[0009] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0010] Optionally, the disc cutting machine includes a frame, a feeding cylinder, and a cutting assembly. The feeding cylinder is rotatably mounted on the upper end face of the frame. The upper center of the frame is fixedly connected to a material distribution cone, and the lower end of the material distribution cone is fixedly connected to the center of a receiving disc. The periphery of the receiving disc and the inner surface of the feeding cylinder are clearance-fitted. The receiving disc is provided with a material discharge port, which is connected to the cutting cavity. The cutting assembly includes a cutting shaft and multiple cutting blades. The cutting shaft is rotatably mounted inside the cutting cavity, and the multiple cutting blades are arranged sequentially on the side of the cutting shaft.

[0011] Optionally, the disc cutting machine further includes a driven wheel, a drive wheel, and multiple load-bearing wheel sets. The driven wheel is fixedly connected to the lower circumference of the feed cylinder. The multiple load-bearing wheel sets are evenly distributed on the frame around the feed cylinder. Each load-bearing wheel set includes an upper limit wheel and a lower load-bearing wheel. The wheel surface of the driven wheel is disposed between the upper limit wheel and the lower load-bearing wheel.

[0012] Optionally, the first mixer and the second mixer have the same structure, both including a housing and two spiral mixing shafts. The two spiral mixing shafts are arranged side by side in the housing. The end of one spiral mixing shaft is fixedly connected to a first gear, and the end of the other spiral mixing shaft is fixedly connected to a second gear. The first gear meshes with the second gear. A feed inlet is provided on the upper side of one end of the housing, and a discharge outlet is provided on the lower side of the other end of the housing.

[0013] Optionally, the water inlet tank is connected to the housing of the first mixer via a water supply pipe, and the bacterial cell tank is connected to the housing of the second mixer via a liquid supply pipe.

[0014] Optionally, the first, second, and third material distribution bins have the same structure, each including a bin body, a conveyor belt mechanism, and a pushing mechanism. The upper end of the bin body is provided with a feed inlet, the conveyor belt mechanism is located at the lower end of the bin body, and the pushing mechanism is located above the conveyor belt mechanism. The pushing mechanism includes a pushing shaft and multiple pushing claws. The two ends of the pushing shaft are respectively rotatably connected to the opposite side walls of the bin body, and are used to drive the multiple pushing claws to rotate, pushing the material to the output end of the conveyor belt mechanism.

[0015] Optionally, the system also includes a first scraper conveyor, a second scraper conveyor, a third scraper conveyor, a fourth scraper conveyor, and a fifth scraper conveyor. The first scraper conveyor is disposed between the disc cutter and the screening machine; the second scraper conveyor is disposed between the screening machine and the first mixer; the third scraper conveyor is disposed between the first mixer and the first distribution bin; the fourth scraper conveyor is disposed between the second distribution bin and the second mixer; and the fifth scraper conveyor is disposed between the second mixer and the third distribution bin.

[0016] Optionally, the screening machine includes a support, a drum, and a drive mechanism.

[0017] Optionally, the aperture of the plurality of screen holes gradually decreases along the elevation angle direction of the central axis of the drum.

[0018] By employing the above technical solution, this utility model has at least the following advantages:

[0019] The straw first enters the disc cutter, and the cut and crushed straw material enters the screening machine to remove dust and impurities from the material, thereby improving the palatability of the subsequent material.

[0020] In the first mixer, while the materials are being mixed, water is introduced from the water tank into the first mixer to adjust the moisture content of the materials.

[0021] After passing through the first feeding bin, the material enters the extruder. The straw is squeezed, rubbed, and sheared in the extrusion chamber, generating high-temperature and high-pressure steam. This causes the lignin between the straw cells and between the cell walls to melt, some hydrogen bonds to break and absorb water, and lignin and cellulose to undergo high-temperature hydrolysis. At the same time, the straw is torn apart, and even the cells are released. The cell walls become loose, and the distribution of lignin between the cells changes, resulting in feed particles becoming smaller and the density increasing.

[0022] The material enters the second mixer through the second distribution bin. While the material is being mixed, bacteria are introduced from the bacterial tank to the second mixer. The bacteria are mainly composed of a complex of microbial strains such as Bacillus subtilis and lactic acid bacteria.

[0023] The materials are transferred through the third material distribution bin to the packaging machine to complete the packaging process.

[0024] By continuously processing straw through cutting, crushing, puffing, fermentation, and baling, the resulting feed is palatable to livestock and features standardized production line processes, thus improving the efficiency of straw puffing processing. Attached Figure Description

[0035] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 As shown, an embodiment of the present invention provides a straw puffing system, which includes: a disc cutter 1, a screening machine 2, a first mixer 3, a first material distribution bin 4, a puffing machine 5, a second material distribution bin 6, a second mixer 7, a third material distribution bin 8, and a baler 9 arranged in sequence.

[0038] The first mixer 3 is connected to the water inlet tank 10, and the second mixer 7 is connected to the bacterial culture tank 11.

[0039] The working process of a straw puffing system is as follows:

[0040] The straw first enters the disc cutter 1, and the cut and crushed straw material enters the screening machine 2 to remove dust and impurities from the material and improve the palatability of the subsequent material.

[0041] In the first mixer 3, while the material is being mixed, water is introduced into the first mixer 3 from the water tank 10 to adjust the moisture content of the material.

[0042] The material enters the extruder 5 through the first feeding bin 4. The straw is squeezed, rubbed and sheared in the extrusion chamber, generating high temperature and high pressure steam. This causes the lignin between the cells and between the cell walls of the straw to melt, some hydrogen bonds to break and absorb water, and lignin and cellulose to undergo high temperature hydrolysis. At the same time, the straw is torn up, and even the cells are released. The cell walls become loose, the distribution state of lignin between cells changes, and the feed particles suddenly become smaller and the density increases.

[0043] The material enters the second mixer 7 through the second distribution bin 6. While the material is being mixed, bacteria are introduced from the bacterial tank 11 into the second mixer 7. The bacteria are mainly composed of a compound of microbial strains such as Bacillus subtilis and lactic acid bacteria.

[0044] The material passes through the third material distribution bin 8 and then reaches the packaging machine 9 to complete the packaging process.

[0045] By continuously processing straw through cutting, crushing, puffing, fermentation, and baling, the resulting feed is palatable to livestock and features standardized production line processes, thus improving the efficiency of straw puffing processing.

[0046] like Figure 2 As shown, specifically, the extruder 5 includes a drive motor, an extrusion cylinder 501, and a spiral shaft 502 coaxially arranged inside the extrusion cylinder. One end of the extrusion cylinder 501 is connected to the upper side of the feed hopper, and the other end of the extrusion cylinder 501 is provided with a discharge port. A deflector wheel 503 is rotatably arranged inside the feed hopper. The deflector wheel is driven and connected to the spiral shaft. Multiple grooves are evenly distributed on the circumference of the shaft side of the deflector wheel. The output shaft of the drive motor is driven and connected to the spiral shaft, so that the spiral shaft and the deflector wheel rotate synchronously. The groove volume of the deflector wheel is determined, so that the feed flow rate of the extrusion cylinder is continuously stable.

[0047] like Figure 3 and Figure 4 As shown, in a specific embodiment, the disc cutting machine 1 includes a frame 101, a feeding cylinder 102, and a cutting assembly 103. The feeding cylinder 102 is rotatably disposed on the upper end face of the frame 101. The upper center of the frame 101 is fixedly connected to a material distribution cone 104. The lower end of the material distribution cone 104 is fixedly connected to the center of a receiving disc 105. The periphery of the receiving disc 105 and the inner surface of the feeding cylinder 102 are clearance-fitted. The receiving disc 105 is provided with a material discharge port, which is connected to a cutting cavity 106. The cutting assembly 103 includes a cutting shaft and multiple cutting blades. The cutting shaft is rotatably disposed within the cutting cavity 106, and the multiple cutting blades are arranged sequentially on the axial side of the cutting shaft.

[0048] In this embodiment, specifically, during the operation of the disc cutter 1, straw is fed into the feeding cylinder 102 from top to bottom. Due to the action of the dispersing cone 104, the straw spreads towards the inner wall of the feeding cylinder 102. The feeding cylinder 102 drives the straw to rotate, and the straw is evenly spread on the receiving disc 105. When the straw reaches the discharge port, the rotating cutting blade picks up the straw and cuts it. The cut straw falls from the lower end of the cutting cavity 106.

[0049] like Figure 3 and Figure 4 As shown in the specific embodiment, the disc cutting machine 1 further includes a driven wheel 107, a drive wheel 108, and a plurality of load-bearing wheel sets. The driven wheel 107 is fixedly connected to the lower circumference of the feed cylinder 102. The plurality of load-bearing wheel sets are evenly distributed on the frame 101 on the circumference of the feed cylinder 102. Each load-bearing wheel set includes an upper limit wheel 110 and a lower load-bearing wheel 109. The wheel surface of the driven wheel 107 is disposed between the upper limit wheel 110 and the lower load-bearing wheel 109.

[0050] In this embodiment, specifically, the driven wheel 107 is a chain, which is welded to the lower circumference of the feed cylinder 102 in a ring. The drive wheel 108 is a sprocket, which meshes with the chain. The drive wheel 108 is driven by a motor, thereby causing the feed cylinder 102 to rotate. The wheel surface of the driven wheel 107 is located between the upper limit wheel 110 and the lower support wheel 109, which limits the position of the feed cylinder 102 and ensures the coaxiality of the feed cylinder 102 and the support disc 105. At the same time, the feed cylinder 102 and the lower support wheel 109 roll and rub against each other, reducing the resistance to the rotation of the feed cylinder 102.

[0051] like Figure 5 and Figure 6As shown, in a specific embodiment, the first mixer 3 and the second mixer 7 have the same structure, both including a housing 301 and two spiral mixing shafts 302. The two spiral mixing shafts 302 are arranged side by side in the housing 301. The end of one spiral mixing shaft 302 is fixedly connected to a first gear, and the end of the other spiral mixing shaft 302 is fixedly connected to a second gear. The first gear meshes with the second gear. A feed inlet is provided on the upper side of one end of the housing 301, and a discharge outlet is provided on the lower side of the other end of the housing 301.

[0052] In this embodiment, specifically, the first gear and the second gear are located outside the housing 301. A drive motor is installed outside the housing 301. The drive motor drives one of the spiral stirring shafts 302 to rotate through a belt pulley. Due to the meshing relationship between the first gear and the second gear, the first spiral stirring shaft 302 and the second spiral stirring shaft 302 rotate synchronously. The spiral blades 204 of the first spiral stirring shaft 302 and the spiral blades 204 of the second spiral stirring shaft 302 push the material forward while stirring it, so that the material is discharged into the outlet of the housing 301.

[0053] Specifically, the upper surface of the bottom plate of the housing 301 is fixedly connected to the triangular body 303, and the triangular body 303 is disposed between the first spiral stirring shaft 302 and the second spiral stirring shaft 302.

[0054] like Figure 1 As shown, in a specific embodiment, the water inlet tank 10 is connected to the housing 301 of the first mixer 3 via a water supply pipe, and the bacterial cell tank 11 is connected to the housing 301 of the second mixer 7 via a liquid supply pipe.

[0055] In this embodiment, water or bacteria are mixed with the materials to adjust the moisture content or the degree of fermentation of the materials.

[0056] like Figure 9 As shown, in a specific embodiment, the first material distribution bin 4, the second material distribution bin 6, and the third material distribution bin 8 have the same structure, each including a bin body 401, a conveyor belt mechanism, and a pushing mechanism 403. The upper end of the bin body 401 is provided with a feed inlet, the conveyor belt mechanism is located at the lower end of the bin body 401, and the pushing mechanism 403 is located above the conveyor belt mechanism. The pushing mechanism 403 includes a pushing shaft and multiple pushing claws. The two ends of the pushing shaft are respectively rotatably connected to the opposite side walls of the bin body 401, and are used to drive the multiple pushing claws to rotate, pushing the material to the output end of the conveyor belt mechanism.

[0057] In this embodiment, specifically, the actuating shaft is arranged along the width direction of the conveying surface of the conveyor belt mechanism. The actuating shaft drives the actuating claw to rotate. While the conveyor belt mechanism moves the material forward, the actuating claw further throws the material out to the output end of the conveyor belt mechanism. During the above process, the material is always inside the hopper 401 to prevent the material from scattering on the ground.

[0058] Specifically, it also includes a servo motor, which is installed on the outside of the housing 401, and the output shaft of the servo motor is coaxially connected to the actuation shaft.

[0059] like Figure 1 As shown, in a specific embodiment, it also includes a first scraper conveyor 12, a second scraper conveyor 13, a third scraper conveyor 14, a fourth scraper conveyor 15, and a fifth scraper conveyor 16. The first scraper conveyor 12 is disposed between the disc cutter 1 and the screening machine 2, the second scraper conveyor 13 is disposed between the screening machine 2 and the first mixer 3, the third scraper conveyor 14 is disposed between the first mixer 3 and the first distribution bin 4, the fourth scraper conveyor 15 is disposed between the second distribution bin 6 and the second mixer 7, and the fifth scraper conveyor 16 is disposed between the second mixer 7 and the third distribution bin 8.

[0060] In this embodiment, specifically, scraper conveyors are installed between different devices to ensure the stability of material conveying and the production continuity of the puffing system.

[0061] like Figure 7 and Figure 8 As shown, in a specific embodiment, the screening machine 2 includes a support 201, a drum 202, and a drive mechanism. The support 201 has an upper inclined surface, and the axial direction of the drum 202 extends along the inclined direction of the upper inclined surface. The drum 202 has a lower inlet and an upper outlet. The drum wall of the drum 202 is evenly distributed with a plurality of screen holes 203. The inner side of the drum 202 is fixedly connected to a spiral blade 204. The drive mechanism includes a drive roller shaft 205, a driven roller shaft 206, and an upper limit wheel 110. The drive roller shaft 205 and the driven roller shaft 206 are symmetrically arranged on the upper inclined surface. The drive roller shaft 205, the driven roller shaft 206, and the upper limit wheel 110 respectively contact the peripheral side of the drum 202.

[0062] In this embodiment, specifically, a dust collection bin 208 is fixedly installed on the support 201, and the dust collection bin 208 is located below the drum 202. The straw material cut and crushed by the disc cutter 1 enters the drum 202 from the lower inlet. The drive roller shaft 205 outputs power to drive the drum 202 to rotate. The spiral blades 204 inside the drum 202 drive the material to move to the upper outlet. The drive roller shaft 205 and the driven roller shaft 206 provide support for the drum 202. The upper end of the support 201 is fixedly connected to the lower end of the arc frame, and the upper limit wheel 110 is rotatably connected to the upper end of the arc frame. The drive roller shaft 205 and the driven roller shaft 206 are respectively axially arranged with multiple rollers 209. Multiple annular slide rails 210 are sequentially axially arranged on the peripheral sidewall of the drum 202. Each annular slide rail 210 corresponds to a roller 209 or an upper limit wheel 110, which is used to prevent the drum 202 from sliding downward along the upper inclined surface of the support 201.

[0063] like Figure 7 As shown, in a specific embodiment, along the elevation angle direction of the central axis of the roller 202, the aperture of the plurality of sieve holes 203 gradually decreases.

[0064] In this embodiment, specifically, during the process of the material moving towards the upper outlet of the drum 202, large dust particles are first screened out of the drum 202 through the large-diameter sieve holes 203 on the lower side wall of the drum 202, while small dust particles are screened out of the drum 202 through the small-diameter sieve holes 203 on the upper side wall of the drum 202 as the material moves upward. In the above process, particles of different sizes are gradually screened out, ensuring the palatability of the material in subsequent processing.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
