Description

Technical Field

[0001] The present invention belongs to the field of straw feed production, and specifically relates to a square bale grass and puffed grass production line. Background Art

[0002] As the main by-product of agricultural production, crop straw is a huge resource with wide distribution. As a large agricultural country, China produces hundreds of millions of tons of straw every year in a wide variety of types, including rice straw, wheat straw, corn straw, cotton straw, etc. However, due to the lack of efficient machinery for the resource utilization of crop straw, the straw is burned in the fields every year across the country, wasting resources and polluting the environment.

[0003] The utilization of straw as feed is the process of converting crop straw into animal feed. The fiber feed processed by crushing straw is the main feed for ruminants. The utilization of straw as feed is of great significance in agricultural production. First, it can effectively solve the environmental pollution caused by straw burning and improve the rural ecological environment; second, the utilization of straw as feed can increase the added value of straw, increase farmers' income and promote the sustainable development of agriculture; finally, straw feed can also provide rich feed resources for animal husbandry, alleviate the problem of feed shortage and promote the healthy development of animal husbandry.

[0004] In the prior art, straw feed processing technology mainly includes physical method, chemical method and biological method. Physical method includes methods such as crushing, soaking, cutting, briquetting, cooking, radiation, etc. Physical method can separate the combination of cellulose, hemicellulose and lignin to a certain extent, destroy the crystal structure of lignocellulose, so as to facilitate animal feeding and appropriately improve digestibility. Chemical treatment method is mainly a method of improving straw digestibility by interacting with the molecular structure of straw by chemical reagents, causing chemical changes in its internal molecules, and the generated products are easy for animals to digest and absorb. Biological method is to use biological processes such as microbial fermentation to convert sugars in straw into organic acids. The straw feed produced by biological method has the advantages of being soft and juicy, sour and fragrant, rich in nutrition, easy to digest, etc. Whether it is physical method, chemical method or biological method, in the actual production process, it is necessary to cut and stir the straw material first, and then perform other processing on it.

[0005] Although straw feed production technology has been greatly developed, the industrial production process of existing small and medium-sized straw feed production enterprises still has some defects. At present, there is an unreasonable utilization structure of production equipment in small and medium-sized straw feed production enterprises, which results in a production line that can only produce a single type of feed. This one-line single-yield production method limits the production range of the production line. If the enterprise wants to expand the production types of feed, it needs to invest more space and equipment, but small and medium-sized enterprises have limited funds and space investment in production, so small and medium-sized straw feed production enterprises are not suitable for one-line single-yield production lines. Utility Model Content

[0006] The purpose of this scheme is to provide a square bale grass and puffed grass production line to solve the problem of first-line yield of small and medium-sized straw feed production enterprises.

[0007] In order to achieve the above-mentioned purpose, the present scheme provides a square bale grass and puffed grass production line, including: a first production line and a second production line, the first production line is connected to the second production line in sequence, the first production line includes a crushing and kneading machine and a first TMR feed mixer arranged in sequence, the first production line also includes a square bale baler and a first wrapping machine, the first TMR feed mixer is connected to the square bale baler in sequence, the first TMR feed mixer is connected to the first wrapping machine in sequence, the mixing bin of the first TMR feed mixer is fixedly connected to the assembled bacteria liquid tank and water tank, the second production line includes a straw puffing machine, a second TMR feed mixer and a second wrapping machine arranged in sequence, the first TMR feed mixer is connected to the straw puffing machine in sequence, and the mixing bin of the second TMR feed mixer is fixedly connected to the assembled bacteria liquid tank.

[0008] The principle and effect of this scheme are as follows: (1) This scheme uses a TMR feed mixer to mix the cut straw. When the TMR feed mixer only uses the mixing function, it can produce mixed grass feed; when the TMR feed mixer mixes, it uses the optional bacterial liquid tank and water tank to add bacteria and honey to produce fermented grass feed; after the fermented grass feed produced by the TMR feed mixer is puffed and then bacteria and honey are added again to produce anaerobic reaction, puffed micro-storage grass can be produced. (2) The square bale baler used in this scheme can pack the mixed grass feed into mixed grass square bales, the first wrapping machine used in this scheme can pack the fermented grass feed into fermented grass bacteria bags, and the second wrapping machine used in this scheme can pack the produced puffed micro-storage grass.

[0009] In summary: This solution provides a square bale grass and puffed grass production line, which can produce three types of straw feed: mixed grass square bales, fermented grass fungus bags and puffed micro-storage grass, solving the problem of first-line yield of small and medium-sized straw feed production enterprises.

[0010] Furthermore, the first production line also includes a rope collecting pool, a scrambler and a drum dust removal screen which are arranged in sequence, and the drum dust removal screen is sequentially connected to the crushing and kneading machine.

[0011] After the straw material is sent into the rope collection pool, the rope untying machine cuts off the binding ropes of the straw material. The cut binding ropes are rolled and screened by the drum screen and collected in the rope collection pool. This method can avoid the binding ropes and straw materials from mixing, resulting in a decline in feed quality and even affecting livestock health. The scattering machine can fully scatter and separate the straw material, making it easier to screen and cut the straw material. The drum dust removal screen can screen the straw material into different categories according to the particle size of the straw material. When cutting, it can more accurately reduce the number of cutting times for smaller straw materials and more accurately increase the number of cutting times for larger straw materials, so as to achieve the effect of uniform particle size of the straw material. In the actual production process, in order to achieve the effect of uniform particle size of the straw material, the working time is usually sacrificed to over-cut the straw material, but the method of mixing and cutting the straw material with uneven particle size will increase the cutting time, and over-cutting will increase the working time. It can be seen that the method of screening first and then cutting can reduce the working time and thus improve production efficiency.

[0012] Furthermore, the first production line also includes a feed bin, which is sequentially connected to the rope collection pool.

[0013] Setting up a feed bin can prevent the operator from coming into direct contact with the rope collecting pool, thereby improving production safety. The rope untying machine in the rope collecting pool contains sharp blades, which may be blocked by the straw during the cutting process, causing the operator to be unable to judge the position of the blades. When the operator loads the straw, it is very likely to cause cuts. Setting up a feed bin can prevent the operator from coming into direct contact with the blades, thereby directly preventing cuts and improving production safety.

[0014] Furthermore, the discharge points of the first TMR feed mixer and the second TMR feed mixer are equipped with magnetic plates.

[0015] In the actual production process, iron wire, thin iron sheets, broken blades, etc. may be mixed in the straw materials. If livestock accidentally eat these iron wire, thin iron sheets, broken blades, etc., it will scratch the esophagus and digestive system, causing losses to herders. The magnetic plate can absorb and remove the iron wire, thin iron sheets, broken blades, etc. in the straw materials during the discharging process to avoid injuries caused by livestock accidentally eating them.

[0016] Furthermore, it also includes a conveying device, and a conveying device is provided between each device on the first production line and the second production line.

[0017] Compared with manual transportation, adding a conveying device, on the one hand, speeds up the transmission of production materials between equipment and reduces the time wasted in manual transportation, thereby improving production efficiency; on the other hand, the load of the conveying device is more controllable, and controllable load makes the work process more controllable, making the production progress easier to control.

[0018] Furthermore, it also includes a main controller, which is electrically connected to the breaking device of the breaking machine.

[0019] It is more convenient to adjust the amplitude, frequency and inclination of the disperser through the main controller than to directly operate the disperser; adjusting the amplitude, frequency and inclination of the disperser according to the straw material can make the disperser operation more suitable for the specific situation of the straw material, so that the disperser can better adapt to the mixing of various straw materials.

[0020] Furthermore, the master controller is electrically connected to the rotating device of the drum dust removal screen, and the master controller is electrically connected to each conveying device respectively.

[0021] By using the master controller to control and adjust the speed and inclination of the drum dust removal screen, it is more convenient to adjust the screening standard according to the different conditions of the straw material, screen the straw material more finely, and make the screened straw material more conducive to the crushing machine to crush it to different degrees.

[0022] Furthermore, the spray device in the crushing and kneading machine is electrically connected to the main controller.

[0023] This way, the main controller can automatically adjust the moisture content and crushing degree of the material during the straw material crushing process, making the crushing process more controllable and the crushing product more stable.

[0024] Furthermore, the bacteria liquid tank and the water tank of the first TMR feed mixer are both provided with quantitative valves, and the bacteria liquid tank of the second TMR feed mixer is provided with a quantitative valve.

[0025] The quantitative valve can be set to limit the time and amount of adding bacteria and honey when producing different feeds. When producing mixed grass square bales, the quantitative valve of the first TMR feed mixer is not opened; when producing fermented grass bacteria bags or puffed micro-storage grass, the quantitative valve is opened quantitatively at different production steps.

[0026] Furthermore, the quantitative valve is electrically connected to the main controller.

[0027] This method can more conveniently and accurately control the time and amount of adding bacteria and honey. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the concept and technical effects of the present invention in combination with the embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention:

[0032] Embodiment 1:

[0033] like Figure 1 As shown, a first production line of a square bale grass and puffed grass production line includes a feeding bin 2, a rope collecting pool 3, a disperser 4, a drum dust screen 5, a crushing and kneading machine 6, a first TMR feed mixer 7 and a square bale baler 15. The feeding bin 2, the rope collecting pool 3, the disperser 4, the drum dust screen 5, the crushing and kneading machine 6, the first TMR feed mixer 7 and the square bale baler 15 are connected in sequence through a conveying device 14. The feeding bin 2, the rope collecting pool 3, the disperser 4, the drum dust screen 5, the crushing and kneading machine 6, the first TMR feed mixer 7 and the square bale baler 15 can all select existing straw feed production equipment according to production needs. For example, the feeding bin 2 can select a straw feeding bin, the disperser 4 can select a straw disperser, and the drum dust screen 5 can select a straw feed drum dust screen.

[0034] The first TMR feed mixer 7 is equipped with a bacterial liquid tank and a water tank, which are fixedly bonded to the mixing bin of the first TMR feed mixer 7. The bacterial liquid tank and the water tank are used to add bacteria and honey to the mixing bin. A magnetic plate (a magnetic plate with high magnetic strength) is provided at the discharge of the first TMR feed mixer, and the magnetic plate is used to absorb iron wire, blades, iron sheets, etc. passing through the outlet.

[0035] A feeder 9 is also provided between the square bale baler 15 and the conveyor 14 , and the feeder 9 can be a feeder matched with the square bale baler 15 .

[0036] A square bale grass and puffed grass production line also includes a loader 1, which can be a straw loader or other transportation equipment. The loader 1 is used to transport the straw materials required for production into a feed bin 2. The loader 1 is also used to transport the mixed grass square bales produced by the square bale baler 15 to the loading area of ​​the factory.

[0037] The main controller is electrically connected to each device on the first production line, and is used to control the opening or closing of each device respectively; the main controller is also electrically connected to the dispersing device of the dispersing machine, and is used to control and adjust the amplitude, frequency and inclination of the dispersing machine; the main controller is also electrically connected to the rotating device of the drum dust removal screen, and is used to control and adjust the rotation speed and inclination of the drum dust removal screen; the spray device in the crushing and kneading machine is electrically connected to the main controller, and is used to automatically adjust the degree of crushing of the crushing and kneading machine; the main controller is also electrically connected to the quantitative valves on the bacteria liquid tank and the water tank, and is used to control the amount of bacteria liquid tank and water tank added.

[0038] In specific implementation: Use the operator as a producer on the square bale and expanded grass production line.

[0039] The operator loads the straw material into the silo 2 through the loader 1, and the conveyor 14 connected to the silo 2 conveys the straw material to the rope collection pool 3 (the capacity of the silo 2 is 8-10 tons / hour). The rope untying machine in the rope collection pool 3 rotates the cutter head to cut the ropes of the straw material, and the cut ropes are removed by the rolling screen in the rope collection pool 3, and then all the ropes are collected in the rope collection pool 3. The untied straw material is transported to the scatterer 4 through the conveyor 14 (the capacity of the scatterer 4 is 8-10 tons / hour).

[0040] The scatterer 4 (the capacity of the scatterer 4 is 8-10 tons / hour) separates and scatters the straw materials by vibration and gravity. When the scatterer 4 scatters the straw materials, the operator notices that the scattering efficiency of the straw materials in the scatterer 4 is not high. The operator determines that the current straw materials are more suitable for a scattering method with higher amplitude, frequency change, and larger inclination angle. Therefore, the operator increases the amplitude, adjusts the frequency change, and increases the inclination angle of the scatterer 4 by operating the master controller. After the operator's adjustment, different types of materials in the straw materials gradually show hierarchical separation according to the types of straw materials. As the scatterer 4 continues to work, all the straw materials are fully scatter, and the scattering straw materials are transported to the drum dust removal screen 5 (the drum dust removal screen 5 is mainly composed of a screen box, a motor, a reducer, a drum, and a bracket, etc., with a capacity of 8-10 tons / hour) via the connected conveying device 14.

[0041] Before the straw material is conveyed to the drum dust screen 5 , the operator determines that the current straw material needs to be screened more finely according to the layer separation situation presented during the breaking, so the operator controls the main controller to increase the speed and inclination of the drum dust screen 5 .

[0042] When the straw material is transported to the drum dust screen 5, it first enters the screen box from the feed port of the drum dust screen 5, and then the drum of the drum dust screen 5 starts to rotate, and the straw material is constantly turned and rolled in the drum, and the larger particles in the straw material are filtered out by the screen inside the drum dust screen 5 (the screen 1 is composed of multiple layers of screens with different apertures, and the larger particles will be blocked in the upper part of the screen), while the smaller particles pass through the screen (the smaller the particles, the more layers of screens they pass through, and the smallest particles can pass through all screens) and fall into the discharge port below, and the discharge port is connected to the nut of the conveying device 14.

[0043] After the straw material is processed by the drum dust screen 5, the conveying device 14 transports the screened straw material to the crushing and kneading machine 6 (with a production capacity of 8-10 tons / hour, its structure mainly includes a feeding structure, a chopping mechanism, a throwing mechanism, a transmission mechanism, a walking mechanism, a protective device and a frame, etc., with the characteristics of reasonable structure, easy movement, automatic feeding, safety and reliability). Before the straw material is transported to the crushing and kneading machine 6, the operator sets the particle size after crushing through the main controller according to the coarseness and fineness requirements of the crushing degree.

[0044] After the straw material enters the crushing and kneading machine 6, the main controller automatically adjusts the moisture content and the degree of crushing of the material according to the green, dry and wet straws and the coarseness of the straw material after crushing by using the multi-hole spray device in the feeding hopper. The straw material is transported to the kneading chamber through the conveyor inside the crushing and kneading machine 6. The crushing and kneading machine 6 crushes the straw material through the interaction between the high-speed rotating hammer and the kneading plate, and then the crushed straw material is thrown to the conveying device 14 behind the crushing and kneading machine 6 through the throwing fan blades in the crushing and kneading machine 6.

[0045] The crushed straw material is transported to the first TMR feed mixer 7 (capacity 8-10 tons / hour) through the conveyor 14. The first TMR feed mixer 7 mainly completes the work tasks in the following steps:

[0046] (1) Adding straw materials. The operator can choose to use the connected conveying device 14 to add the straw materials crushed by the crushing and kneading machine 6 to the first TMR feed mixer 7, or can choose a straw feeding conveyor to complete the adding work.

[0047] (2) Weighing and metering of straw materials. During the process of adding straw materials, the bridge-type weighing sensors at four positions in the first TMR feed mixer 7 transmit signals to the weighing display. The operator checks the gross weight, net weight, peak value and weight change output zero through the display, and completes the feed proportioning and weighing without triggering the overload alarm function of the first TMR feed mixer 7 (the triggering of the overload alarm function indicates that the material is added too much, and the operator needs to remove the overloaded part of the material from the first TMR feed mixer 7).

[0048] (3) Transmission, mixing and stirring of straw materials. The transmission system in the first TMR feed mixer 7 (the transmission system consists of double sprockets, double chains, a main shaft and two secondary shafts, the two sprockets and double chains are connected to the secondary shaft, and the main sprocket is connected to the secondary shaft through the chain, so that the main and secondary shafts rotate and complete the transmission at the same time) rotates and stirs the straw materials from all directions at both ends of the box to the middle position of the mixer in the first TMR feed mixer. The moving blades (located on each spiral lead on the auger screw) and the fixed teeth (located on the center line of the feed mixer) of the transmission system of the first TMR feed mixer cut the straw materials, so that various fibrous grass materials and straws in the straw materials are cut and stirred, achieving the effect of crushing and mixing evenly.

[0049] (4) Discharging of straw materials. After the transmission, mixing and stirring of the straw materials are completed, the operator starts discharging, and the discharging sliding baffle of the discharging door (composed of a hydraulic cylinder, a fixed support, a linkage support, and a sliding discharging baffle, and the discharging door is nut-connected with the conveying device 14) in the first TMR feed mixer 7 opens, and the hydraulic cylinder transports the straw materials from the first TMR feed mixer 7 to the conveying device 14 through the reciprocating motion of the reciprocating shaft. At the same time, during the discharging process, the magnetic plate at the discharging port removes iron from the straw materials (adsorbs and removes iron wire, thin iron sheets, broken blades, etc.).

[0050] The conveying device 14 conveys the mixed straw material to the feeder 9, and the feeder 9 conveys the mixed straw material to the compression chamber of the square bale baler 15 (capacity 8-10 tons / hour). After the straw material enters the compression chamber, it is subjected to heat pressing by the compressor in the compression chamber. The compressor compresses the straw material to a certain thickness and size, and with the assistance of the compression box in the compression chamber, the straw material is packaged and fixed. After the packaging and fixing is completed, a mixed grass square bale 17 is obtained, and the square bale baler 15 will make a sound at this time, indicating that the work is completed. After the operator hears the sound of the square bale baler 15, he uses the loader 1 to load the mixed grass square bale 17 into the warehouse.

[0051] Example 2

[0052] The difference from Example 1 is that:

[0053] like Figure 1 As shown, the first production line for producing fermented straw bacteria bag 9 adds the bacteria liquid tank and water tank matched with the first TMR feed mixer 7 to the first TMR feed mixer 7. After the bacteria liquid tank and water tank are installed on the first TMR feed mixer 7, the quantitative pumps of the bacteria liquid tank and the water tank are controlled to be turned on or off by the main controller. The first wrapping machine 16 of the first production line uses a 70 wrapping machine.

[0054] When implementing: Use operators as producers.

[0055] When the first production line does not produce mixed grass bales, the operator uses the first production line to produce fermented grass fungus bags 9. The pre-production process of the fermented grass fungus bags 9 is the same as the production process of the mixed grass bales 17, and the same parts will not be repeated in this embodiment.

[0056] The difference is that when the straw material enters the first TMR feed mixer 7 to complete the straw material weighing and metering step, the operator checks the gross weight, net weight, peak value and weight change data displayed on the display, and calculates the amount of bacteria and honey added in this production. The operator controls the switch and release of the bacteria liquid tank and the water tank metering pump through the main controller, and adds the corresponding metered bacteria liquid into the first TMR feed mixer 7 through the metering pump to complete the perfect mixing of the material and the bacteria liquid.

[0057] After the fermented material produced by the first production line is fed into the conveyor 14, the conveyor 14 conveys the material to the first wrapping machine 16, and the sealing system of the first wrapping machine 16 wraps and seals the fermented material to obtain a fermented straw mushroom bag 9. After the fermented straw mushroom bag 9 is completely sealed, it enters the shrinking system of the first wrapping machine 16, and the shrinking system shrinks the packaging film of the fermented straw mushroom bag 9 by heating and fixes it on the surface of the fermented straw mushroom bag 9. Finally, the packaged fermented straw mushroom bag 9 is conveyed to the loading area of ​​the factory by the conveyor belt of the first wrapping machine 16 to complete the warehousing work.

[0058] The fermented grass fungus bag 9 produced by the fermented grass fungus bag 9 production line in Example 2 has increased palatability and digestibility when eaten by livestock. The key is that compared with silage grass, the feed waste rate is reduced by 20-30%, and the nutrition remains unchanged.

[0059] Example 3

[0060] The difference from Example 1 and Example 2 is that:

[0061] like Figure 1 As shown, a straw puffing machine 8, a second TMR feed mixer 11 and a second wrapping machine 12 are sequentially arranged in the second production line. The straw puffing machine 8 uses an existing straw puffing machine. The second TMR feed mixer 11 can select a TMR feed mixer of the same model as the first TMR feed mixer 7, but compared with the first TMR feed mixer 7 on the first production line, it is only equipped with a bacteria liquid tank but not a water tank. The second wrapping machine 12 is the same as the first wrapping machine 16, and a 70 wrapping machine is also selected. The second wrapping machine 12 has the same working mode as the first wrapping machine 16.

[0062] When implementing: Use operators as producers.

[0063] When the first production line does not produce the mixed grass bales 17 and the fermented grass mushroom bags 9, the second production line is used to produce the puffed micro-storage grass 13. The pre-production process of the puffed micro-storage grass 13 is the same as the production process of the fermented grass mushroom bags 9, and the same parts will not be repeated in this embodiment.

[0064] The difference is that after the fermentation material produced by the first production line is sent into the conveyor 14, the conveyor 14 conveys the fermentation material into the straw extruder 8, and the screw in the straw extruder 8 pushes the fermentation material to form an axial flow. At the same time, due to the mutual friction between the screw and the fermentation material, between the fermentation material and the barrel in the straw extruder 8, and between the fermentation material, the fermentation material is strongly squeezed, stirred, and sheared, and then the fermentation material is refined and homogenized. At the same time, the straw extruder 8 directly converts the mechanical energy in the process of squeezing, stirring, and shearing the fermentation material into heat energy, and instantly generates high temperature and high pressure in the extrusion chamber of the straw extruder 8 (a high temperature of 120-140 is formed in the extrusion chamber), and then drops sharply at the discharge port of the straw extruder 8 to form a spray expansion, so as to achieve the purpose of maturation and saccharification of the fermentation material. This method effectively separates the straw cellulose, hemicellulose and lignin in the fermentation material, breaks the waxy membrane, and fully releases the digestible nutrients in the cells. The straw puffing machine 8 delivers the produced puffed material to the conveying device 14 from the discharge port, and the conveying device 14 transports the puffed material to the second TMR feed mixer 11.

[0065] The second TMR feed mixer 11 adds honey and bacteria to the received puffed material, so that the straw is fully in contact with microorganisms and enzymes, and the nutritional content and utilization value of the straw are improved. Probiotics are then added to the puffed material for anaerobic fermentation to complete the chemical changes of the straw. The production of puffed micro-storage grass 13 transforms the straw from waste with low utilization rate into "straw puffed biological feed" that is easy to absorb, rich in nutrition, and green and ecological. The puffed micro-storage grass 13 is then transported to the second wrapping machine 12 using the conveyor 14, and the product production of the puffed micro-storage grass 13 is completed through the processing of the second wrapping machine 12 (70 wrapping machine).

[0066] Compared with dry straw, the nutrient content of the puffed micro-storage grass 13 was greatly improved, including crude protein content increased by more than 50%, crude fat content increased by 67.65%, indigestible cellulose and hemicellulose content decreased, and lignin content decreased by 50.09%. Compared with silage, the feed waste rate was reduced by 20-30% when feeding livestock.

[0067] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
