Abstract
Description
Technical Field
[0001] This invention relates to the field of feed processing technology, and more specifically, to a method and equipment system for processing beef cattle feed by wrapping a mixture of straw and distiller's grains into micro-silage. Background Technology
[0002] Beef cattle farming can make extensive use of roughage resources such as crop straw, realizing the "returning straw to the field after it passes through the stomach," turning waste into treasure, and reducing the pollution of straw waste to the environment. At the same time, liquor production enterprises produce a large amount of liquor lees every year. These lees contain crude protein as well as rich amino acids, vitamins, and yeast, which can improve the rumen microecological environment and promote growth. They can be added to beef cattle farming.
[0003] In existing technologies, straw-based feed ingredients have low protein and energy content, which cannot meet the nutritional needs of beef cattle. Although distillers' grains contain rich nutrients, their high moisture content of 60% to 70% makes them highly susceptible to rancidity and spoilage. Furthermore, they contain a certain amount of alcohol, and excessive feeding can negatively impact the rumen microecological environment and digestive function of beef cattle, making them unsuitable for direct use as feed ingredients. During the wrapping process of mixed straw and distillers' grains for micro-storage, the significant differences in physical properties between straw (fibrous structure) and distillers' grains (powdered or lumpy structure) make it difficult to ensure feed quality. Conventional wrapping machines use ropes for wrapping, resulting in large gaps between the ropes. Fine particles easily scatter through these gaps, leading to uneven component content in each wrap, unstable micro-storage fermentation quality, and difficulty in guaranteeing feed quality.
[0004] Existing technologies have technical problems such as uneven component content due to fine particles scattering during the wrapping process of mixed materials, high labor intensity and low production efficiency due to reliance on manual operation in the wrapping process, and difficulty in achieving continuous and automated production. Summary of the Invention
[0005] This invention provides a method and equipment system for processing mixed silage feed of straw and liquor lees for beef cattle, which solves the technical problems in related technologies, such as uneven content of components due to fine particle dispersion during the coating process, high labor intensity and low production efficiency due to reliance on manual operation in the coating process, and difficulty in achieving continuous and automated production.
[0006] This invention discloses a processing equipment system for coating mixed micro-silage of straw and distiller's grains for beef cattle, including a coating machine. The coating machine comprises a frame, a coating chamber, a feeding device, a mixing and stirring device, a coating unit, a weighing and metering device, and a linkage mechanism. The coating chamber is located on the frame and is used to hold the material to be coated. The mixing and stirring device is located on top of the coating machine and includes a mixing drum and a stirring mechanism. The stirring mechanism includes a mixing shaft and mixing blades, with the mixing blades spirally distributed on the outer circumference of the mixing shaft. The stirring mechanism is used to mix the straw segments and distiller's grains powder. The feeding device connects the mixing and stirring device and the coating chamber, and is used to transport the mixed material into the coating chamber. The wrapping device includes a wrapping net rope, a net rope storage mechanism, and a net rope release mechanism. The wrapping net rope is a rope with a mesh structure, and the mesh size of the wrapping net rope is smaller than the particle size of the distillers' grains. The net rope storage mechanism is used to store the wrapped net rope in a wound state. The net rope release mechanism is used to release the wrapping net rope and wrap it around the outer surface of the material in the wrapping chamber. A weighing and measuring device is installed in the wrapping chamber and is used to monitor the weight of the material in the wrapping chamber in real time. A linkage mechanism is connected to the weighing and measuring device, the feeding device, and the wrapping device. The linkage mechanism is used to control the feeding device to stop feeding and control the wrapping device to perform the wrapping action when the weighing and measuring device detects that the weight of the material has reached a preset value.
[0007] This invention discloses a method for processing beef cattle straw and liquor lees mixed micro-silage, and the steps are performed according to the equipment system for processing beef cattle straw and liquor lees mixed micro-silage.
[0008] Furthermore, the mixing drum has an inlet and an outlet. The outlet of the mixing drum is connected to the inlet of the feeding device. The mixing shaft is arranged along the central axis of the mixing drum. One end of the mixing shaft passes through the mixing drum and is connected to the drive motor. The spiral pushing action of the mixing blades causes the material to form a composite motion trajectory of up-and-down tumbling and back-and-forth pushing within the mixing drum.
[0009] Furthermore, the wrapping chamber is a cylindrical cavity located in the middle of the frame, the cylindrical cavity extends vertically, the top of the cylindrical cavity is an open structure forming a material inlet, and the discharge end of the feeding device is located above the material inlet.
[0010] Furthermore, the rope storage mechanism includes a rope storage drum and a winding shaft. The winding shaft is rotatably connected inside the rope storage drum, and the wrapping rope is wound around the winding shaft. The rope release mechanism includes a guide wheel assembly and a release control device. The guide wheel assembly is disposed on the path between the rope storage mechanism and the wrapping chamber. The wrapping rope extends to the inner wall of the wrapping chamber after passing through the guide wheel assembly. The release control device is connected to the winding shaft. The release control device is used to release the locking of the winding shaft after receiving a trigger signal, so that the wrapping rope unfolds and wraps around the outer surface of the material.
[0011] Furthermore, the weighing and metering device includes a weighing sensor and a metering controller. The weighing sensor is located at the bottom of the wrapping chamber, and the bottom of the wrapping chamber is supported on the frame by the weighing sensor. The metering controller is electrically connected to the weighing sensor and is used to receive the electrical signal from the weighing sensor and calculate the weight of the material. The metering controller outputs a trigger signal when the weight of the material reaches a preset value.
[0012] Furthermore, the linkage mechanism includes a control unit and an execution unit. The control unit is electrically connected to the metering controller and is used to generate control commands after receiving a trigger signal output by the metering controller. The execution unit includes a feeding control module and a wrapping control module. The feeding control module is electrically connected to the drive motor of the feeding device and is used to cut off the power supply to the drive motor after receiving the control command. The wrapping control module is electrically connected to the release control device and is used to drive the release control device to release the locking of the winding shaft after receiving the control command.
[0013] Furthermore, the wrapping device also includes a wrapping film winding mechanism, which is located on the outside of the wrapping chamber. The wrapping film winding mechanism is used to wrap a wrapping film around the outer surface of the wrapping after the wrapping net rope is wrapped. The wrapping film is a plastic film with stretchability and adhesion. The wrapping film winding mechanism spirally wraps the wrapping film around the outer surface of the wrapping to form a sealing layer through rotational movement.
[0014] Furthermore, the equipment system also includes an unloading device, which is located on the side of the wrapping machine. The unloading device includes a robotic arm and a gripping mechanism. The gripping mechanism is located at the end of the robotic arm and includes clamping claws. The clamping claws are two symmetrically arranged jaws, which are driven by a hydraulic cylinder or a pneumatic cylinder to achieve opening and closing movements. The unloading device is used to grab the finished product that has been wrapped from the wrapping chamber and transfer it to a designated position.
[0015] Furthermore, the unloading device also includes a position sensing device and a control system. The position sensing device includes a vision sensor, which is used to acquire image information of the finished package. The control system is electrically connected to the linkage mechanism and the drive device of the unloading device. After receiving the package completion signal, the control system determines the spatial coordinates and attitude angle of the finished package through an image recognition algorithm. The control system plans the motion trajectory of the unloading device based on the spatial coordinates and attitude angle.
[0016] This invention solves the technical problem of unstable component content in the mixed materials by setting a mixing and stirring device on the top of the wrapping machine. It utilizes the spiral pushing and turning action of the stirring blades to achieve full mixing of straw segments and distiller's grains powder, so that fibrous materials and powdery materials are evenly interwoven, avoiding the stratification phenomenon caused by differences in physical properties. This achieves the technical effect of providing homogenized raw materials for subsequent wrapping.
[0017] This invention replaces traditional rope with a wrapping net, utilizing the net structure to form a dense constraint layer. The mesh size is designed to be smaller than the particle size of the distiller's grains. The interlacing of the mesh structure forms a physical barrier to prevent fine particles from passing through the mesh and scattering, thus maintaining a stable mass ratio of straw segments to distiller's grains in each finished wrapper. This solves the technical problem of uneven component content caused by material scattering and achieves the technical effect of ensuring stable quality of micro-silage.
[0018] This invention, by configuring a weighing and metering device and a linkage mechanism on a wrapping machine, converts the material weight into an electrical signal and transmits it to the metering controller in real time. Once the metering controller determines that the material weight has reached a preset value, it immediately outputs a trigger signal. Upon receiving the trigger signal, the linkage mechanism automatically controls the feeding device to stop and the wrapping device to start. The entire process requires no manual intervention. The automated control mechanism eliminates errors and delays caused by manual judgment and operation, solves the technical problems of inconsistent wrapping weights and low production efficiency, and achieves the technical effect of achieving precise control according to the preset weight and improving production efficiency.
[0019] This invention, by configuring an unloading device in the equipment system, automatically moves to the wrapping chamber and performs a gripping action after receiving the wrapping completion signal. The gripping mechanism clamps the finished wrapping package with precise force control, avoiding damage to the wrapping film while ensuring reliable clamping. The entire handling process does not require workers to engage in heavy physical labor. The automatic coordination between the unloading device and the wrapping machine enables continuous production, solving the technical problems of discontinuous production and excessive labor load for workers. It achieves the technical effects of realizing continuous automated production and significantly reducing labor intensity. Attached Figure Description

[0021] The beef cattle industry faces multiple technical challenges in utilizing crop straw and liquor production waste. Straw-based feed ingredients have low protein and energy content, failing to meet the nutritional needs of beef cattle. While liquor lees are rich in crude protein, amino acids, vitamins, and yeast, their high moisture content of 60-70% makes them highly susceptible to rancidity and spoilage. Furthermore, their alcohol content, if excessive, can negatively impact the rumen microecological environment and digestive function of beef cattle, rendering them unsuitable for direct use as feed.
[0022] In the baling process of mixed straw and distiller's grains for micro-silage, the significant differences in physical properties between straw (fibrous structure) and distiller's grains (powdered or lumpy structure) cause fine particles to easily scatter from the gaps in the fibrous material during baling. This results in uneven component content in each bale, unstable micro-silage fermentation quality, and difficulty in guaranteeing feed quality. Traditional baling machines use ropes for baling, but the gaps between the ropes are relatively large, failing to effectively prevent the scattering of fine particles. Furthermore, the baling process relies heavily on manual operation for material mixing, feeding, metering, baling, and handling, leading to high labor intensity, low production efficiency, and difficulty in achieving continuous and automated production.
[0023] Therefore, there is a need for a method and equipment system for wrapping and processing mixed micro-silage of straw and liquor lees for beef cattle that can effectively prevent the mixture from scattering, ensure the uniform and stable content of each component, and achieve continuous and automated processing.
[0024] like Figure 1-6 As shown in the embodiment, according to the present embodiment, a processing equipment system for wrapping mixed micro-silage of beef cattle straw and distillers' grains is provided. The processing equipment system for wrapping mixed micro-silage of beef cattle straw and distillers' grains includes at least a wrapping machine, which includes a frame 4, a wrapping chamber 8, a feeding device and a wrapping device 2.
[0025] The frame 4 serves as the basic structure supporting the entire wrapping machine. A wrapping chamber 8 is mounted on the frame 4; the wrapping chamber 8 is a space for accommodating materials to be wrapped and for wrapping them. A feeding device is connected to the wrapping chamber 8 and is used to transport the mixed materials into the wrapping chamber 8. A wrapping device 2 is located in the wrapping chamber 8 and is used to wrap and shape the materials within the wrapping chamber 8.
[0026] In some embodiments, the frame 4 is a rectangular frame structure, which is a stable support frame formed by welding or bolting together columns and beams.
[0027] In some embodiments, the wrapping chamber 8 is a cylindrical container located in the middle of the frame 4. The cylindrical container extends in a vertical direction and includes a cylindrical body and a bottom plate. The top of the cylindrical body is an open structure forming a material inlet, and the bottom plate closes the bottom end of the cylindrical body.
[0028] In some embodiments, the feeding device is a conveyor belt 1 mechanism, the discharge end of the conveyor belt 1 mechanism is located above the material inlet of the wrapping chamber 8, and the conveyor belt 1 mechanism drives the material to be conveyed into the wrapping chamber 8.
[0029] Furthermore, in order to achieve thorough mixing of materials before wrapping, a mixing and stirring device 7 is installed on the top of the wrapping machine. The mixing and stirring device 7 is connected to the feeding device and is used to mix and stir the materials before they enter the feeding device.
[0030] In some embodiments, the mixing device 7 includes a mixing drum and a mixing mechanism. The mixing drum is a container disposed on the top of the frame 4, and the mixing drum has an inlet and an outlet. The outlet of the mixing drum is connected to the inlet end of the feeding device. The mixing mechanism is disposed inside the mixing drum and is used to drive the materials inside the mixing drum to mix.
[0031] In some embodiments, the stirring mechanism includes a stirring shaft and stirring blades. The stirring shaft is arranged along the central axis of the stirring drum, and both ends of the stirring shaft are supported at the ends of the stirring drum by bearing seats. One end of the stirring shaft extends out of the stirring drum and is connected to a drive motor through a coupling. The drive motor drives the stirring shaft to rotate. The stirring blades are fixed to the outer circumferential surface of the stirring shaft by bolts. The stirring blades are arranged in a spiral shape. When the stirring shaft rotates, the stirring blades drive the material to be spirally pushed and tumbled for mixing.
[0032] Furthermore, in order to prevent fine particulate materials in the mixture from scattering during the wrapping process, the wrapping device 2 includes a wrapping net rope. The wrapping net rope is a rope with a mesh structure. The mesh size of the wrapping net rope is smaller than the particle size of the fine particulate materials. The wrapping net rope can block the scattering of fine particulate materials.
[0033] In some embodiments, the wrapping netting is woven from polyethylene or polypropylene, and the mesh size of the wrapping netting is two to five millimeters.
[0034] Furthermore, to achieve automatic wrapping of the wrapping netting, the wrapping device 2 also includes a netting storage mechanism and a netting release structure 6. The netting storage mechanism is located on the upper part of the frame 4 and is used to store the wrapped wrapping netting in its wound state. The netting release structure 6 connects the netting storage mechanism and the wrapping chamber 8, and is used to release the wrapping netting from the netting storage mechanism and wrap it around the outer surface of the material in the wrapping chamber 8 when preset conditions are met.
[0035] In some embodiments, the rope storage mechanism includes a rope storage drum and a winding shaft. The rope storage drum is a container located on the upper part of the frame 4. The two ends of the winding shaft are supported by bearings on the inner wall of the rope storage drum. The winding shaft can rotate around its own axis, and the wrapping rope is wound around the winding shaft.
[0036] In some embodiments, the netting release structure 6 includes a guide wheel assembly and a release control device. The guide wheel assembly is disposed on the path between the netting storage mechanism and the wrapping chamber 8. The wrapping netting extends to the inner wall of the wrapping chamber 8 after passing through the guide wheel assembly. The release control device includes a locking mechanism and a drive mechanism. The locking mechanism is disposed on the winding shaft and includes a brake disc and a brake caliper. The brake disc is fixed to the end of the winding shaft, and the brake caliper clamps the brake disc to keep the winding shaft locked. The drive mechanism is an electromagnet or a cylinder. The drive mechanism is connected to the brake caliper. After receiving a trigger signal, the drive mechanism drives the brake caliper to release the brake disc. After the winding shaft is unlocked, the wrapping netting is released under pretension. Under the combined action of tension and gravity, the wrapping netting automatically unfolds and wraps around the outer surface of the material.
[0037] Furthermore, in order to achieve wrapping and weighing according to a preset weight, the wrapping machine also includes a weighing and measuring device, which is installed in the wrapping chamber 8 and is used to monitor the weight of the material in the wrapping chamber 8 in real time.
[0038] In some embodiments, the weighing and metering device includes a weighing sensor and a metering controller. The weighing sensor is disposed at the bottom of the wrapping chamber 8, and the bottom plate of the wrapping chamber 8 is supported on the frame 4 by the weighing sensor. The weight of the material in the wrapping chamber 8 is transmitted to the weighing sensor through the bottom plate and converted into an electrical signal. The metering controller is electrically connected to the weighing sensor. The metering controller receives the electrical signal from the weighing sensor and calculates the weight of the material. The metering controller outputs a trigger signal when the weight of the material reaches a preset value.
[0039] In some embodiments, the preset value is 100 kg, and the metering controller outputs a trigger signal when it detects that the weight of the material in the wrapping chamber 8 reaches 100 kg.
[0040] Furthermore, in order to achieve the linkage control between the weighing and metering device, the feeding device, and the wrapping device 2, the wrapping machine also includes a linkage mechanism. The linkage mechanism is connected to the weighing and metering device, the feeding device, and the wrapping device 2 respectively. After receiving the trigger signal from the weighing and metering device, the linkage mechanism controls the feeding device to stop feeding and controls the wrapping device 2 to perform the wrapping action.
[0041] In some embodiments, the linkage mechanism includes a control unit and an execution unit. The control unit is electrically connected to a metering controller, and generates control commands after receiving trigger signals output by the metering controller. The execution unit includes a feeding control module and a wrapping control module. The feeding control module is electrically connected to the drive motor of the feeding device, and cuts off the power to the drive motor after receiving control commands, causing the feeding device to stop operating. The wrapping control module is electrically connected to a release control device, and drives the release control device to release the locking of the winding shaft after receiving control commands.
[0042] In some embodiments, the wrapping device 2 further includes a wrapping film winding mechanism, which is disposed on the outside of the wrapping chamber 8. The wrapping film winding mechanism is used to wrap a wrapping film around the outer surface of the wrapping after the wrapping net rope is wrapped. The wrapping film is a plastic film with stretchability and adhesion.
[0043] Furthermore, the wrapping film winding mechanism includes a rotating bracket 3, a film roll support frame, and a rotating drive device. The rotating bracket 3 is arranged in a ring structure on the outer periphery of the wrapping chamber 8 and is supported by rollers on the frame 4. The film roll support frame is fixed to the rotating bracket 3, and a wrapping film roll is installed on the film roll support frame. After the wrapping film is released from the film roll support frame, it adheres to the outer surface of the wrapping. The rotating drive device is connected to the rotating bracket 3 and drives the rotating bracket 3 to rotate around the central axis of the wrapping chamber 8. When the rotating bracket 3 rotates, it drives the film roll support frame to rotate around the wrapping, and the wrapping film spirally winds around the outer surface of the wrapping to form a sealing layer.
[0044] Furthermore, in order to achieve automatic handling of finished wrappers, the equipment system also includes a wrapping unloading device, which is located on the side of the wrapping machine. The wrapping unloading device is used to grab the finished wrappers from the wrapping chamber 8 and transfer them to the designated location.
[0045] In some embodiments, the unloading device is a robotic arm, which includes a robotic arm and a gripping mechanism. The robotic arm connects multiple levers via rotary joints to form a multi-degree-of-freedom motion structure. The base of the robotic arm is fixed to the ground or frame 4 by bolts. The gripping mechanism is located at the end of the robotic arm and includes gripping claws. The gripping claws are two symmetrically arranged jaws, which are driven by a hydraulic cylinder or a pneumatic cylinder to achieve opening and closing movements. When closed, the gripping claws hold the outer surface of the finished package.
[0046] In some embodiments, the unloading device is a frame 4, which includes a mobile chassis and a working arm. The mobile chassis has a walking function and moves on the ground via a wheel drive mechanism. The working arm is mounted on top of the mobile chassis and includes multiple joints and a gripping mechanism for holding finished packages.
[0047] Furthermore, to achieve automatic coordination between the unloading device and the wrapping machine, the unloading device also includes a position sensor and a control system. The position sensor is installed in the unloading device and is used to detect the position and orientation of the finished wrapped package. The control system is electrically connected to the linkage mechanism of the wrapping machine and the drive device of the unloading device. After receiving the wrapping completion signal, the control system drives the unloading device to move to position 8 in the wrapping chamber and executes the gripping action.
[0048] In some embodiments, the position sensing device includes a vision sensor, which is a camera. The vision sensor acquires image information of the finished package, and the control system determines the spatial coordinates and attitude angle of the finished package through an image recognition algorithm. The control system plans the motion trajectory of the unloading device based on the spatial coordinates and attitude angle.
[0049] According to an embodiment of this invention, the method for processing beef cattle silage using a mixture of straw and distiller's grains includes the following steps: Step 1, Raw Material Pretreatment: Obtain straw and liquor lees as raw materials. Dry the liquor lees to reduce their moisture content, and then pulverize the dried liquor lees to form liquor lees powder. Cut the straw into straw segments with a length of two to three centimeters.
[0050] In some embodiments, the drying process of the baijiu lees in step one is carried out by hot air drying, with the hot air temperature controlled at 60 to 80 degrees Celsius and the drying time being four to six hours. The moisture content of the dried baijiu lees is reduced to 10% to 15%.
[0051] In some embodiments, the crushing process of the baijiu lees in step one is carried out using a hammer mill, and the particle size of the crushed baijiu lees powder is two to five millimeters.
[0052] In some embodiments, the straw cutting process in step one is carried out using a straw chopper, with the blade spacing of the straw chopper set to two to three centimeters, so that the straw is formed into uniform straw segments after passing through the straw chopper.
[0053] Step 2, ingredient mixing: The distiller's grains powder, straw segments and compound microbial agent are put into the mixing drum of the mixing device 7 according to the preset ratio. The mixing mechanism of the mixing device 7 drives the materials to mix thoroughly, and the components of the mixed materials are evenly distributed.
[0054] In some embodiments, the mass ratio of distiller's grains powder to straw segments in step two is 1:3, and the addition ratio of compound microbial agent is 0.004% of the total mass of the mixture.
[0055] In some embodiments, the mixing time of the mixing device 7 in step two is five to ten minutes, the rotation speed of the mixing shaft is thirty to fifty revolutions per minute, and the spiral pushing action of the mixing blades causes the material to form a composite motion trajectory of up-and-down tumbling and back-and-forth pushing in the mixing drum, ensuring that the components are fully contacted and evenly dispersed.
[0056] Furthermore, step two also includes a moisture adjustment process, during which an appropriate amount of water is added according to the actual moisture content of the material during the mixing process, and the moisture content of the mixed material is controlled at 60% to 70%.
[0057] Step 3, material conveying: The mixing drum of the mixing device 7 discharges the mixed material through the discharge port to the feeding device, which continuously conveys the material to the wrapping chamber 8, where the material accumulates under gravity.
[0058] In some embodiments, the feeding device in step three adopts a conveyor belt 1 mechanism. The operating speed of the conveyor belt 1 is 0.5 to 1 meter per second. The discharge end of the conveyor belt 1 maintains a height difference of 20 to 30 centimeters with the material inlet of the wrapping chamber 8, and the material falls freely into the wrapping chamber 8.
[0059] Step 4, Weighing and Metering: The weighing and metering device monitors the cumulative weight of the materials in the wrapping chamber 8 in real time. The weighing sensor converts the weight of the materials into an electrical signal and transmits it to the metering controller. The metering controller determines whether the weight of the materials has reached the preset value.
[0060] In some embodiments, in step four, the metering controller adopts a real-time sampling method with a sampling frequency of 10 Hz. The metering controller filters the sampled data to eliminate vibration interference and compares the filtered data with a preset value.
[0061] Step 5, linkage control: When the material weight reaches the preset value, the metering controller outputs a trigger signal to the linkage mechanism. After receiving the trigger signal, the linkage mechanism controls the feeding device to stop running and controls the wrapping device 2 to start the wrapping action.
[0062] In some embodiments, after receiving the trigger signal in step five, the linkage mechanism first controls the drive motor of the feeding device to be powered off. The feeding device stops completely after a delay of 0.5 to 1 second due to inertia. Then, the linkage mechanism controls the release control device of the wrapping device 2 to release the lock of the winding shaft.
[0063] Step 6, Net Rope Wrapping: The net rope release structure 6 of the wrapping device 2 releases the wrapping net rope from the net rope storage mechanism. After being guided by the guide wheel group, the wrapping net rope unfolds and wraps around the outer surface of the material in the wrapping chamber 8. The mesh structure of the wrapping net rope adheres to the outer surface of the material to form a constraint layer, which prevents fine particles in the material from scattering.
[0064] In some embodiments, the wrapping net rope in step six is pre-tensioned. The wrapping net rope on the winding shaft is subjected to constant tension in the storage state. After the release control device is unlocked, the wrapping net rope unfolds rapidly under the combined action of tension and gravity. During the unfolding process, the wrapping net rope generates friction with the outer surface of the material, causing the wrapping net rope to adhere tightly to the outer surface of the material.
[0065] Furthermore, step six also includes the outer membrane winding process. After the wrapping net rope is wrapped, the wrapping film winding mechanism is activated. The wrapping film winding mechanism rotates around the outer surface of the wrapping and releases the wrapping film simultaneously. The wrapping film is spirally wrapped around the outside of the wrapping net rope to form a sealing layer. The sealing layer isolates the outside air and creates an anaerobic environment for micro-storage fermentation.
[0066] In some embodiments, the rotation speed of the wrapping film winding mechanism during the outer film winding process is 10 to 15 revolutions per minute, the stretching rate of the wrapping film is controlled at 50% to 70%, and the number of wrapping film layers is four to six.
[0067] Step 7, Unpacking the finished product: After the wrapping is completed, the unpacking device moves to the wrapping chamber 8. The gripping mechanism of the unpacking device clamps the finished product wrapping and removes it from the wrapping chamber 8. The unpacking device then transports the finished product wrapping to the storage area or fermentation area.
[0068] In some embodiments, the unloading device in step seven is a robotic arm. The control system drives the robotic arm to move so that the gripping mechanism approaches the finished package. After the gripping claws open, they envelop the outer contour of the finished package. After the gripping claws close, the gripping force is controlled at fifty to one hundred Newtons. The gripping force ensures that the finished package does not fall off and does not damage the wrapping film.
[0069] In some embodiments, the unloading device in step seven is a frame 4. After receiving the wrapping completion signal, the control system plans the movement path of the frame 4. The mobile chassis drives the frame 4 to move along the planned path to the side of the wrapping chamber 8. The working arm extends and adjusts the posture of the gripping mechanism so that the gripping mechanism is aligned with the axis of symmetry of the finished wrapping. After the gripping mechanism clamps the finished wrapping, the working arm retracts. The mobile chassis drives the frame 4 to transport the finished wrapping to the designated position.
[0070] Step 8, Micro-storage Fermentation: The finished product is packaged and micro-storage fermented in the storage area. During the fermentation process, the microorganisms in the compound microbial agent decompose the cellulose, hemicellulose and protein in the straw and liquor lees. The fermentation products include organic acids and aroma substances.
[0071] In some embodiments, the fermentation time in step eight is fifteen days when the ambient temperature is high in summer and extended to thirty days when the ambient temperature is low in winter. After fermentation, the micro-stored feed has an aroma of wine and sourness, and the pH value of the micro-stored feed drops to 3.8 to 4.2.
[0072] This embodiment achieves thorough mixing of straw segments and distiller's grains powder before they enter the wrapping chamber 8 by installing a mixing and stirring device 7 at the top of the wrapping machine. The mixing mechanism of the mixing and stirring device 7 uses a spiral pushing and tumbling action to evenly interweave the fibrous straw segments and powdered distiller's grains powder, avoiding stratification caused by differences in physical properties, thus overcoming the problem of uneven material mixing in traditional methods. The thoroughly mixed material has a uniform distribution of its components, providing homogenized raw materials for subsequent wrapping, thus solving the problem of unstable component content in the mixed material.
[0073] This embodiment uses wrapping netting instead of traditional rope, utilizing the netting's mesh structure to form a dense constraint layer. The mesh size of the wrapping netting is designed to be smaller than the particle size of the distiller's grains. When the wrapping netting wraps around the outer surface of the material, the interlacing of the mesh structure forms a physical barrier, preventing fine particles such as distiller's grains from passing through the mesh and scattering. This overcomes the problem of fine particles scattering due to the large gaps in traditional ropes. The constraint effect of the wrapping netting ensures a stable mass ratio of straw segments to distiller's grains in each finished bale, thus solving the problem of uneven component content caused by material scattering.
[0074] This embodiment achieves real-time monitoring and automated control of material weight by configuring a weighing and metering device and a linkage mechanism on the wrapping machine. The weighing sensor converts the material weight into an electrical signal, which is transmitted to the metering controller in real time. Once the metering controller determines that the material weight has reached a preset value, it immediately outputs a trigger signal. Upon receiving the trigger signal, the linkage mechanism automatically controls the feeding device to stop and the wrapping device 2 to start. The entire process requires no manual intervention. This automated control mechanism eliminates errors and delays caused by manual judgment and operation, thus overcoming the problems of high labor intensity and low production efficiency associated with manual operation. The weighing and metering device ensures that the weight of each finished wrapper accurately reaches the preset value, thereby solving the problems of inconsistent wrapping weights and low production efficiency.
[0075] This embodiment achieves automated handling of finished product wrappers by configuring an unloading device in the equipment system. Upon receiving a wrapping completion signal, the unloading device automatically moves to position 8 in the wrapping chamber and performs a gripping action. The gripping mechanism uses precise force control to clamp the finished product wrapper, avoiding damage to the wrapping film while ensuring reliable clamping. After transporting the finished product wrapper to the designated location, the unloading device releases it. The entire handling process requires no manual labor from workers, thus overcoming the problem of high labor intensity in manual handling. The automatic coordination between the unloading device and the wrapping machine allows for continuous production, thereby solving the problems of discontinuous production and excessive worker workload.

The beef cattle straw and distiller's grains mixed micro-silage coating and processing equipment system according to any one of claims 1 to 9 performs the following steps: Step 1, raw material pretreatment: Obtain straw and liquor lees as raw materials, dry the liquor lees to reduce its moisture content, crush the dried liquor lees to form liquor lees powder, and cut the straw to form straw segments. Step 2, Ingredient Mixing: The distiller's grains powder, the straw segments, and the compound microbial agent are added into the mixing drum of the mixing device according to a preset ratio. The mixing mechanism of the mixing device drives the materials to mix, and the mixed materials are evenly distributed in each group. Step 3, material conveying: The mixing drum of the mixing device discharges the mixed material through the discharge port to the feeding device, which continuously conveys the material to the wrapping chamber; Step 4, Weighing and Metering: The weighing and metering device monitors the cumulative weight of the material in the wrapping chamber in real time. The weighing sensor converts the material weight into an electrical signal and transmits it to the metering controller. The metering controller determines whether the material weight has reached the preset value.
