Description

Technical Field

[0001] This invention belongs to the technical field of lifting and conveying devices, and specifically discloses a conveying device and method for production using a hydraulic cattle and sheep extrusion press. Background Technology

[0002] Hydraulic beef and mutton extruders (also known as meat-bone separators) are widely used in large slaughterhouses, meat processing plants, and enterprises that comprehensively utilize by-products after cattle and sheep slaughter to process meat-bearing bones, skeletons, and other by-products. This equipment uses high pressure generated by a hydraulic system to crush the bones and expel residual meat scraps, marrow, and soft tissue from the bones through a screen, achieving separation of meat and bone. This transforms slaughter waste into high-value-added meat paste (commonly used in pet food, luncheon meat, hot pot ingredients, etc.) and industrial bone residue. The meat chunks or minced meat produced by the extruder are typically irregular rectangular blocks with a certain degree of stickiness. In actual production, this type of material needs to be transferred to subsequent cooling, packaging, or freezing processes via a conveying device. Currently, the industry commonly uses scraper conveyors as the main conveying equipment, which has advantages such as simple structure, strong conveying capacity, and adaptability to high-viscosity materials. However, existing scraper conveyors have the following technical problems when conveying extruded beef and mutton chunks:

[0003] Firstly, the material discharged from the extruder is usually intermittent, resulting in uneven distribution of material entering the conveyor within the scraper space, often leading to stacking—that is, the material accumulation height in a single scraper space exceeds the height of the scraper itself. When the conveyor has an inclination angle (especially the lifting section), these stacked material blocks are prone to roll over the top of the scraper under the influence of gravity and fall downwards in the conveying direction. The rolling material may become stuck between the chain and the housing, causing the equipment to jam or the chain to break.

[0004] Secondly, the temperature of extruded beef and mutton chunks is relatively high (usually 15-25℃) when they exit the extruder, and they are rich in protein, fat, and moisture, making them an ideal substrate for microbial growth. Even short periods of residence in a normal temperature transport environment can lead to a large-scale proliferation of microorganisms. Although psychrophilic bacteria can still grow slowly at low temperatures, the reproduction of most spoilage bacteria (such as Pseudomonas and Enterobacteriaceae) is significantly inhibited below -10℃. Furthermore, the unsaturated fatty acids in meat are highly susceptible to oxidative rancidity when exposed to air, resulting in a rancid odor; simultaneously, the myoglobin on the meat surface undergoes a browning reaction upon contact with oxygen, giving the product a grayish-brown appearance, severely impacting its sensory quality and commercial value. Existing conveying equipment lacks effective means of controlling ambient temperature, making it impossible to cool the material in a timely manner during transport, thus shortening the product's shelf life.

[0005] In summary, the existing technology lacks an integrated conveying device that can simultaneously solve the problem of stacking and rolling during the conveying of compressed beef and mutton chunks, and can effectively protect the material at low temperatures during the conveying process, thereby inhibiting microbial growth, delaying fat oxidation and surface browning. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a conveying device for the production of hydraulic cattle and sheep extrusion presses, including a base frame, an extrusion molding box, an extrusion molding machine, a lifting scraper conveyor, and a low-temperature cooling mechanism. The bottom of the extrusion molding machine is fixedly installed above the extrusion molding box, and the bottom of the extrusion molding box is fixedly installed on the top of the base frame. A hopper is provided at the lower outer end of the lifting scraper conveyor. The extrusion molding machine is controlled by a hydraulic gate for material feeding from the lower inside. A discharge platform is fixedly installed on one side of the base frame near the lower part of the hydraulic gate. The hopper is located below the discharge platform. U-shaped plates are fixedly installed on both sides of the lifting scraper conveyor. The low-temperature cooling mechanism is mounted above the two sets of U-shaped plates. A slide is connected between the two sets of U-shaped plates by a reciprocating mechanism. A driving component is provided at one end of the slide, and a horizontal pushing block is provided outside the driving component. A bracket is fixedly installed at one end of the slide, and a vision camera is fixedly installed on the upper part of the bracket. A feeding platform is provided on the upper side of one side of the extrusion molding box.

[0007] In the above technical solution, the low-temperature cooling mechanism further includes an installation box, which is mounted on two sets of U-shaped plates near the middle. Two liquid storage tanks are installed inside the installation box. The two liquid storage tanks are connected to a pump body through a gas mist generator heat exchanger at the lower end. A diversion pipe is installed at the lower end of the pump body. A mounting frame is fixedly connected to the bottom of the installation box. Multiple square tubes are embedded inside the mounting frame. The multiple square tubes are connected to the internal parts of the corresponding diversion pipes. Multiple atomizing nozzles are connected to the lower ends of the multiple square tubes.

[0008] In the above technical solution, arc-shaped covers are fixedly installed on the exterior of both the front and rear ends of the mounting box, and the bottom of the two arc-shaped covers is fixedly connected to the top of the U-shaped plate.

[0009] In the above technical solution, further, guide plates are fixedly installed on the inner walls of the two sets of U-shaped plates that are close to each other, and guide vanes are installed at equal intervals along the horizontal direction on the outer surface of the guide plates.

[0010] In the above technical solution, the reciprocating mechanism further includes a lead screw and a slide bar, which are arranged in parallel between two sets of U-shaped plates. The slide frame has screw holes adapted for threaded connection of the lead screw and slide holes adapted for sliding connection of the slide bar on both sides. A rotary motor is fixedly installed at one end of the lead screw. The rotary motor is fixedly installed on the outer wall of the lifting scraper conveyor through a base. A collection box is provided at the bottom inside the lifting scraper conveyor.

[0011] In the above technical solution, the driving component further includes a lifting rod, a telescopic rod is provided on the lower surface of one end of the lifting rod, the telescopic rod is fixedly installed on the upper surface of the slide, the lifting rod slides through the inside of the slide, a sleeve is fixedly installed at the bottom end of the lifting rod, a dual-axis motor is fixedly installed inside the sleeve, a connecting rod is fixedly installed at both ends of the dual-axis motor, a stop rod is fixedly connected between the two connecting rods, and multiple rubber strips are wrapped around the lower part of the stop rod.

[0012] In the above technical solution, the flat-push swing block includes two sets of inclined rods, which are respectively fixedly installed on both sides of the outer side of the casing. An arc-shaped cleaning plate is fixedly installed at the lower end of each set of inclined rods, and multiple arc-shaped scrapers corresponding to the positions of the rubber strips are installed inside the arc-shaped cleaning plate.

[0013] A method for using a conveying device produced by a hydraulic cattle and sheep extruder, based on the aforementioned conveying device, includes the following steps:

[0014] S1: The extrusion molding machine extrudes and molds the material. The molded material is temporarily stored inside the extrusion molding box. The material is discharged through the hydraulic gate and slides into the hopper through the unloading table.

[0015] S2: The lifting scraper conveyor lifts and transports the material in the hopper upwards. During the conveying process, the vision camera records the stacking status of the material in each scraper space in real time. When it is detected that the stacking height of the material exceeds the height of the scraper, the signal is transmitted to the external control device.

[0016] S3: The control device drives the reciprocating mechanism to move the carriage to the position of the stacked materials. The driving component drives the flat-push swing block to reciprocate, pushing the stacked materials to both sides and spreading them flat in the scraper space. This prevents the materials from rolling down to the outside during the conveying process and ensures the safety of the conveying.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By coordinating a vision camera with a reciprocating mechanism and a horizontally pushing block, accurate identification and automatic leveling of stacked materials are achieved. Specifically, the vision camera records the material stacking status in each scraper space in real time at the lower end of the lifting scraper conveyor. When the stacking height exceeds the scraper height, the reciprocating mechanism moves the carriage into the scraper space, and the drive unit drives the horizontally pushing block to reciprocate, pushing the stacked material to both sides and leveling it, and then quickly detaching it. This structure effectively solves the problems of equipment jamming, chain breakage, and batch mixing caused by material stacking and rolling in the lifting section of traditional conveyors, ensuring the continuity and safety of the conveying process, while reducing manual intervention and improving the level of production automation.

[0019] 2. This invention achieves online cooling and antibacterial action during the conveying process by installing a low-temperature cooling mechanism above the conveyor. The low-temperature cooling mechanism includes a liquid storage tank, an aerosol generator heat exchanger, a pump body, and atomizing nozzles, which can atomize the low-temperature disinfectant and spray it evenly onto the material surface. The combined use of the atomizing nozzles, guide plates, and guide vanes creates a uniform low-temperature environment within the conveyor, effectively inhibiting the growth of putrefactive bacteria on the material surface, delaying fat oxidation and rancidity, and myoglobin browning, thereby significantly extending the product's shelf life. This structure integrates the cooling process into the conveying stage, eliminating the need for separate cooling equipment and reducing equipment footprint and investment costs.

[0020] 3. This invention achieves precise positioning and flexible contact in the leveling action through the linkage design of the reciprocating mechanism and the driving component. The reciprocating mechanism adopts a screw and slide bar cooperation structure, which can accurately control the movement position of the slide along the conveying direction, ensuring that the leveling device accurately reaches the scraper space where the stacked materials are located. The lifting rod in the driving component drives the sleeve and the flat pushing block to rise and fall, and the dual-axis motor drives the abutment rod to reciprocate in a half-circle swing. The rubber strip wrapped around the abutment rod makes flexible contact with the material, which not only ensures the leveling effect but also avoids damage to the material surface. When rotating to one side of the arc-shaped cleaning plate, the rubber strip is squeezed into the arc-shaped scraper shell. Through scraping, the residue on the surface of the rubber strip can be cleaned simultaneously during the leveling process, preventing material adhesion and accumulation, and further improving the hygiene performance of the equipment.

[0021] 4. This invention optimizes the uniformity of low-temperature mist distribution through the airflow organization design of the guide plate and guide vanes. The guide plate is fixedly installed on the inner side of the U-shaped plate, and the guide vanes are arranged at equal intervals along the horizontal direction. This guides the low-temperature airflow ejected from the atomizing nozzle to all areas inside the conveyor, including the outer space where the reciprocating parts and the horizontal pushing blocks are located. This ensures that the material surface and the outer surface of the actuator can be uniformly cooled and sterilized, avoiding the existence of blind spots in local processing, improving the consistency of product quality and the overall cleanliness of the equipment, and preventing local over-wetting or uneven drying. This ensures that all materials receive uniform cooling treatment. Attached Figure Description

Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0032] like Figures 1-7The conveying device shown is for a hydraulic cattle and sheep extrusion press, including a base frame 1, an extrusion molding box 2, an extrusion molding machine 4, a lifting scraper conveyor 8, and a low-temperature cooling mechanism. The bottom of the extrusion molding machine 4 is fixedly installed above the extrusion molding box 2, and the bottom of the extrusion molding box 2 is fixedly installed on the top of the base frame 1. A hopper 6 is provided at the lower end of the lifting scraper conveyor 8. The extrusion molding machine 4 is controlled by a hydraulic gate 5 to discharge material. A discharge platform 14 is fixedly installed on one side of the base frame 1 and below the hydraulic gate 5. The hopper 6 is located below the discharge platform 14. U-shaped plates 9 are fixedly installed on both sides of the lifting scraper conveyor 8. The low-temperature cooling mechanism is mounted above the two sets of U-shaped plates 9. A slide 22 is connected between the two sets of U-shaped plates 9 by a reciprocating mechanism. A drive component is provided at one end of the slide 22. A horizontal pushing block is provided outside the drive component. A bracket 21 is fixedly installed at one end of the slide 22. A vision camera 26 is fixedly installed on the upper part of the bracket 21. A feeding platform 3 is provided on the upper side of one side of the extrusion molding box 2.

[0033] In this embodiment, the vision camera 26 records the material stacking status in each scraper space within the lifting scraper conveyor 8 in real time. When it detects that the stacking height exceeds the scraper height, the external control device drives the reciprocating mechanism to move the slide 22 into the scraper space. The driving component drives the flat-push block to reciprocate, pushing the stacked material to both sides and flattening it. This effectively prevents the material from rolling down over the scraper during the lifting process, avoiding equipment jamming or chain breakage caused by material blockage, and ensuring the continuity and safety of the conveying process. At the same time, the low-temperature cooling mechanism continuously releases low-temperature mist during the conveying process, which rapidly reduces the surface temperature of the material, inhibits microbial growth, and delays fat oxidation and browning, achieving integrated conveying and preservation operations.

[0034] The low-temperature cooling mechanism includes a mounting box 12, which is mounted on two sets of U-shaped plates 9 near the middle. Two liquid storage tanks 11 are installed inside the mounting box 12. The two liquid storage tanks 11 are connected to a pump body 36 through a gas mist generator heat exchanger 15 at the lower end. A diversion pipe 18 is installed at the lower end of the pump body 36. A mounting frame 16 is fixedly connected to the bottom of the mounting box 12. Multiple square tubes are embedded inside the mounting frame 16. The multiple square tubes are connected to the internal parts of the corresponding diversion pipes 18. Multiple atomizing nozzles 17 are connected to the lower ends of the multiple square tubes.

[0035] In this embodiment, the cooling medium in the storage tank 11 evaporates into a low-temperature gas via the atomizing heat exchanger 15. Simultaneously, a trace amount of liquid medium is atomized by the atomizing nozzle 17 and mixes with the low-temperature gas to form a low-temperature mist. The pump body 36 pressurizes and delivers the low-temperature mist to the distribution pipe 18, which distributes it through a square pipe and then evenly releases it into the lifting scraper conveyor 8 via the atomizing nozzle 17. This structure achieves rapid cooling of the material surface through gas-phase heat exchange, avoiding excessive surface wetting caused by liquid spraying, effectively controlling surface water activity, and further reducing the risk of microbial growth while ensuring cooling effect. Furthermore, it requires no chemical disinfectants and fully complies with food production safety regulations.

[0036] Arc-shaped covers 10 are fixedly installed on the exterior of both the front and rear ends of the mounting box 12, and the bottom of the two arc-shaped covers 10 are fixedly connected to the top of the U-shaped plate 9.

[0037] In this embodiment, the arc-shaped cover 10 confines the release area of ​​the low-temperature mist within the lifting scraper conveyor 8, preventing the low-temperature mist from rapidly diffusing outwards and causing rapid loss of cooling energy. Simultaneously, the arc-shaped inner wall structure of the arc-shaped cover 10 guides the mist to flow downwards into the conveyor, enhancing the contact efficiency between the mist and the material surface, resulting in a more concentrated and efficient cooling effect.

[0038] A guide plate 19 is fixedly installed on the inner wall of the side of the two sets of U-shaped plates 9 that are close to each other, and guide vanes 20 are installed at equal intervals along the horizontal direction on the outer surface of the guide plate 19;

[0039] In this embodiment, after the low-temperature mist is released from the atomizing nozzle 17, the guide plate 19 guides the mist to the main area inside the lifting scraper conveyor 8, while the guide vane 20 further evenly disperses the mist to the peripheral areas such as each scraper space, the carriage 22, and the horizontal pushing block. This structure effectively avoids the existence of local cooling blind spots, ensuring that the material surface and key equipment components are uniformly covered by low-temperature mist, improving the consistency of product quality and the overall cleanliness of the equipment, while avoiding local over-wetting or uneven drying.

[0040] The reciprocating mechanism includes a lead screw 23 and a slide bar 24. The lead screw 23 and the slide bar 24 are arranged in parallel between two sets of U-shaped plates 9. The slide frame 22 has screw holes adapted to the threaded connection of the lead screw 23 and slide holes adapted to the sliding connection of the slide bar 24 on both sides. A rotary motor 13 is fixedly installed at one end of the lead screw 23. The rotary motor 13 is fixedly installed on the outer wall of the lifting scraper conveyor 8 through a base. A collection box 7 is provided at the bottom inside the lifting scraper conveyor 8.

[0041] In this embodiment, the external control device starts the rotary motor 13 to drive the lead screw 23 to rotate based on the stacked material position signal fed back by the vision camera 26. The lead screw 23, through its threaded engagement with the slide 22, drives the slide 22 to move precisely horizontally along the slide bar 24 until the stacked material is above the scraper space. The slide bar 24 serves as a guide and stabilizer, ensuring that the slide 22 does not wobble during movement. This reciprocating mechanism has high positioning accuracy and fast response speed, enabling precise and rapid response to the position of the stacked material, providing an accurate positional basis for subsequent leveling operations. The collection box 7 is used to collect residual materials or condensate that may fall during the conveying process, keeping the working environment clean.

[0042] The driving component includes a lifting rod 25, a telescopic rod 28 is provided on the lower surface of one end of the lifting rod 25, the telescopic rod 28 is fixedly installed on the upper surface of the slide 22, the lifting rod 25 slides through the inside of the slide 22, a sleeve 29 is fixedly installed at the bottom end of the lifting rod 25, a dual-axis motor 31 is fixedly installed inside the sleeve 29, a connecting rod 32 is fixedly installed at both ends of the dual-axis motor 31, a stop rod 34 is fixedly connected between the two connecting rods 32, and multiple rubber strips 35 are wrapped around the lower part of the stop rod 34.

[0043] In this embodiment, when the carriage 22 moves to the corresponding scraper space, the telescopic rod 28 is activated, driving the lifting rod 25 to extend downwards, causing the housing 29 and the abutment rod 34 to descend into the scraper space. The dual-axis motor 31 is activated, driving the connecting rods 32 at both ends to swing back and forth synchronously. The connecting rods 32 drive the abutment rod 34 to perform a half-cycle swing motion. The rubber strip 35 on the outside of the abutment rod 34 flexibly contacts the stacked material, pushing the material to both sides of the scraper space to flatten it. The flexible material of the rubber strip 35 can avoid mechanical damage to the surface of the material, while ensuring the effectiveness of the flattening action. After flattening is completed, the telescopic rod 28 drives the lifting rod 25 and the abutment rod 34 to rise and reset, waiting for the next flattening operation. This drive component has a compact structure and flexible operation, and can quickly respond to control commands to achieve precise flattening of stacked materials.

[0044] The horizontal push block includes two sets of inclined rods 27. The two sets of inclined rods 27 are fixedly installed on both sides of the outer side of the sleeve box 29. The lower ends of the two sets of inclined rods 27 are fixedly installed with arc-shaped cleaning plates 30. The arc-shaped cleaning plates 30 are equipped with multiple arc-shaped scrapers 33 corresponding to the positions of the rubber strips 35.

[0045] In this embodiment, during the reciprocating swing of the abutment rod 34 to level the material, when the rubber strip 35 rotates with the connecting rod 32 to a position above one side of the arc-shaped cleaning plate 30, the outer surface of the rubber strip 35 comes into contact with the arc-shaped scraper shell 33. The arc-shaped inner wall of the arc-shaped scraper shell 33 forms a close scraping motion with the outer surface of the rubber strip 35, effectively removing material residues adhering to the surface of the rubber strip 35 and preventing material adhesion and accumulation that could affect subsequent leveling results. This self-cleaning structure completes cleaning synchronously during the intervals of the leveling action, requiring no additional action or manual intervention, ensuring the continuous operation and hygiene performance of the equipment, and avoiding leveling failure or cross-contamination problems caused by material adhesion.

[0046] It should be noted that the external control device is a PLC controller, and an electric heating wire can be installed inside the bracket 21 to automatically heat up in low temperature and high humidity environments to prevent the lens of the vision camera 26 from blurring and to ensure that the vision camera 26 maintains clear recording in foggy environments.

[0047] The lifting scraper conveyor 8 operates at reduced speed, so it can react within the reaction time when pushing the swing block.

[0048] A method for using a conveying device produced by a hydraulic cattle and sheep extruder, based on the aforementioned conveying device, includes the following steps:

[0049] S1: Extrusion molding machine 4 extrudes and molds the material. The molded material is temporarily stored inside the extrusion molding box 2. The material is discharged through hydraulic gate 5 and slides into the hopper 6 via unloading platform 14.

[0050] S2: The lifting scraper conveyor 8 lifts and transports the material in the hopper 6 upwards. During the conveying process, the vision camera 26 records the stacking status of the material in each scraper space in real time. When it is detected that the stacking height of the material exceeds the height of the scraper, the signal is transmitted to the external control device.

[0051] S3: The control device drives the reciprocating mechanism to move the slide 22 to the position of the stacked materials. The driving component drives the flat-push swing block to reciprocate, pushing the stacked materials to both sides and spreading them flat in the scraper space. This prevents the materials from rolling down the scraper to the outside during the conveying process, ensuring the safety of the conveying.

[0052] Working Principle: Cattle and sheep by-product raw materials are fed into the extrusion molding machine 4, where high pressure is applied to the material to form blocks. The formed material falls into the extrusion molding box 2 for temporary storage. The hydraulic gate 5 can be set to open at a time under external control to control the material discharge rate. The material slides down the unloading platform 14 into the hopper 6. The hopper 6 is located at the lower inlet of the lifting scraper conveyor 8, ensuring that the material can be continuously and stably conveyed into the lifting scraper conveyor 8. After the lifting scraper conveyor 8 starts, it drives the scraper to move from bottom to top, lifting the material in the hopper 6 upward along the conveying direction. During the conveying process, the vision camera 26 installed above the bracket 21 records the stacking status of the material in each scraper space in real time. The vision camera 26 transmits the collected image data to the external control device. The control device has a built-in image recognition algorithm that can automatically determine whether the stacking height of the material exceeds the height of the scraper. When the stacking height is detected to be excessive, the reciprocating mechanism is activated. The rotary motor 13 drives the lead screw 23 to rotate, causing the slide 22 to move horizontally along the slide rod 24, precisely positioning the slide 22 above the stacked material in the scraper space. Subsequently, the telescopic rod 28 in the drive unit drives the lifting rod 25 to extend downwards, causing the housing 29 and the flat-push block to descend into the scraper space. The dual-axis motor 31 starts, causing the connecting rods 32 at both ends to swing synchronously. The connecting rods 32 drive the abutment rod 34 to reciprocate in a half-cycle swing motion. The rubber strip 35 wrapped around the abutment rod 34 makes flexible contact with the stacked material, pushing the stacked material to both sides of the scraper space, making the material evenly spread within the scraper space, and preventing the material from rolling downwards over the scraper during the lifting and conveying process. During the swinging of the abutment rod 34, when the rubber strip 35 rotates to the side above the arc-shaped cleaning plate 30, the rubber strip 35 scrapes against the arc-shaped scraper shell 33, removing the material residue attached to the surface, preventing material adhesion and accumulation, and ensuring the continuous effectiveness of the leveling action. After the leveling is completed, the telescopic rod 28 drives the lifting rod 25 and the horizontal pushing block to rise and reset, and the slide 22 moves to the standby position to wait for the next horizontal pushing operation;

[0053] While materials are being conveyed, the cryogenic cooling mechanism operates continuously. Two liquid storage tanks 11 inside the mounting box 12 store food-grade cooling media (such as purified water or food-grade coolant). When the cooling media passes through the atomizing heat exchanger 15, it exchanges heat with the refrigeration elements. The atomizing heat exchanger 15 evaporates the liquid cooling media into cryogenic gas. Simultaneously, a small amount of liquid media is atomized by the atomizing nozzle 17 and mixes with the cryogenic gas to form cryogenic atomization. The pump body 36 pressurizes and delivers the cryogenic atomization to the distribution pipe 18, and then distributes it through multiple square tubes inside the mounting frame 16 to the outlets of each atomizing nozzle 17, evenly releasing it into the lifting scraper conveyor 8. The arc-shaped cover 10 confines the atomization area within the lifting scraper conveyor 8 to prevent rapid overflow. The guide plates 19 and guide vanes 20 on the inner sides of the two sets of U-shaped plates 9 guide the low-temperature mist, ensuring its even distribution throughout the interior of the lifting scraper conveyor 8, including the scraper space, carriage 22, and horizontal sliding blocks. The low-temperature mist makes full contact with the material surface, rapidly removing surface heat through gas-phase heat exchange, achieving rapid cooling. The low-temperature environment significantly inhibits the growth rate of thermophilic and spoilage bacteria, while also delaying the oxidative rancidity of unsaturated fatty acids and the browning reaction of myoglobin in meat products. Compared to liquid spraying, the aerosol solution ensures cooling while avoiding excessive wetting of the material surface, effectively controlling surface water activity, further reducing the risk of microbial growth, and requiring no chemical disinfectants, fully complying with food production safety regulations.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

6. A method of using a conveying device produced by a hydraulic cattle and sheep extruder, based on the conveying device produced by a hydraulic cattle and sheep extruder as described in any one of claims 1-5, characterized in that, Includes the following steps: S1: The extrusion molding machine (4) extrudes and molds the material. The molded material is temporarily stored inside the extrusion molding box (2). The material is discharged through the hydraulic gate (5) and slides into the silo (6) through the unloading platform (14). S2: The lifting scraper conveyor (8) lifts and conveys the material in the hopper (6) upward. During the conveying process, the vision camera (26) records the stacking status of the material in each scraper space in real time. When it is detected that the stacking height of the material exceeds the height of the scraper, the signal is transmitted to the external control device. S3: The control device drives the reciprocating mechanism to move the slide (22) to the position of the stacked material. The drive unit drives the flat push block to reciprocate, pushing the stacked material to both sides so that it is laid flat in the scraper space, preventing the material from rolling down to the outside during the conveying process, and ensuring the safety of the conveying.
