Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] See Figures 1-13As shown, the present invention provides a livestock forage cultivation device for arid and cold regions, including a cultivation rack 1 and a cultivation tray structure 10. An outer isolation cover 8 is provided on the outside of the cultivation rack 1. An outlet 801 and an inlet 802 are respectively opened on both sides of the outer isolation cover 8. An opening and closing door structure 9 for controlling its opening and closing is provided at both the outlet 801 and the inlet 802. The opening and closing door structure 9 includes a door body 901. A third cylinder 902 for driving the door body 901 to open and close is provided on the outer isolation cover 8.

[0023] Material transfer components 4 are respectively installed at the outlet 801 and inlet 802 inside the outer isolation cover 8; The cultivation rack 1 is provided with several first conveyors 2 along the vertical direction for conveying the cultivation tray structure 10. The first conveyors 2 are provided with material transfer reversing components 3 at both ends along their transmission direction. The material transfer reversing components 3 are used to connect and reverse the transmission of the cultivation tray structure 10 between two adjacent first conveyors 2. The cultivation rack 1 is provided with a material spreading component 5 for spreading raw materials into the cultivation tray structure 10. The material spreading component 5 is provided with an internal combing component 7. The cultivation rack 1 is provided with a linear drive component 6 for driving the material spreading component 5 to move.

[0024] See instruction manual attached Figure 4 , Figure 10 and Figure 11 As shown, the cultivation tray structure 10 includes a tray body 1001, which is a rectangular trough-shaped structure with an open top, providing space for forage cultivation. The tray body 1001 has raised edges 1003 on both sides for transmission with the first conveyor 2 and the material transmission assembly 4. Two parallel raised strips 1002 are located on the lower side of the tray body 1001. In practical applications, the cultivation tray structure 10 directly carries the raw materials required for forage cultivation, such as substrate and seeds, forming an independent cultivation unit and preventing material leakage. Simultaneously, its inner width and outer length are precisely matched with the feed hopper 502, the first conveyor 2, and the second conveyor 401 within the device, ensuring compatibility with subsequent material spreading and transmission processes.

[0025] See instruction manual attached Figure 4 , Figure 5 and Figure 13As shown, the material transfer and reversing assembly 3 includes a lifting frame 301. The cultivation rack 1 is provided with a first electric telescopic rod 307 for driving the lifting frame 301 to move up and down. The lifting frame 301 is provided with two sets of support rods 305 distributed vertically for supporting the cultivation tray structure 10. Each set includes two parallel support rods 305. Each support rod 305 has a limiting protrusion 306 on the upper side of the end opposite to the first conveyor 2. A first cylinder 302 is provided below each set of support rods 305. The first cylinder 302 is fixedly mounted on the lifting frame 301. The push rod head of the first cylinder 302 is provided with a first motor 303 facing the first conveyor 2. The output shaft end of the first motor 303 is connected to the push rod head of the first cylinder 302. The first motor 303 is provided with a lever 304 for cooperating with the protrusion 1002 to push and pull the cultivation tray structure 10 for positioning. In practical applications, when the cultivation tray structure 10 needs to be transferred from the upper first conveyor 2 to the lower first conveyor 2, the first electric telescopic rod 307 drives the lifting frame 301 to rise, aligning the upper support rod 305 with the conveyor belt of the upper first conveyor 2. Subsequently, the first motor 303 adjusts the angle of the lever 304 so that it abuts against the protrusion 1002 on the lower side of the cultivation tray. The first cylinder 302 push rod retracts, pulling the cultivation tray from the upper first conveyor to the upper support rod 305 via the lever. The limiting protrusion 306 prevents the cultivation tray from slipping. The first electric telescopic rod 307 drives the lifting frame 301 to descend until the lower support rod 305 is aligned with the conveyor belt of the lower first conveyor 2. At this time, the cultivation tray on the upper support rod descends synchronously with the frame to the target height. The first cylinder 302 push rod extends, pushing the cultivation tray structure 10 from the upper support rod 305 to the conveyor belt of the lower first conveyor 2 via the lever 304, completing one upper and lower layer reversal.

[0026] The material transfer and reversing component 3 in this application solves the problem of cross-layer transmission of cultivation trays in multi-layer cultivation racks through the coordination of various components, realizing fully automated operation of receiving, lifting and feeding without manual intervention, ensuring the accuracy and stability of cultivation tray transmission, and is a key component for the entire cultivation device to achieve multi-layer and automated cultivation.

[0027] See instruction manual attached Figure 4 , Figure 9 and Figure 12 As shown, the material transfer assembly 4 includes a second conveyor 401. The cultivation rack 1 is provided with a second electric telescopic rod 403 for driving the second conveyor 401 to move linearly. The second conveyor 401 is provided with a support lug 404 that is connected to the push rod head of the second electric telescopic rod 403. The cultivation rack 1 is rotatably provided with a support roller 402 for supporting the movement of the second conveyor 401.

[0028] See instruction manual attached Figure 1 , Figure 4 , Figure 8 andFigure 12 As shown, the material spreading assembly 5 includes a storage bin 501. A hopper 502 is located on one side of the lower part of the storage bin 501. The other side of the lower part of the storage bin 501 is inclined from high to low towards the hopper 502. The hopper 502 is located above the material conveying assembly 4 at the inlet 802. The length of the outlet of the hopper 502 is the same as the inner width of the disc body 1001. A feeding wheel 503 is rotatably mounted inside the hopper 502. A second motor 504 is installed inside the feeding wheel 503 to drive its rotation within the hopper 502. The outer side of the feeding wheel 503 is circumferentially... The circumferentially oriented feed trough 505 has three or more feed troughs 505, each with a V-shaped cross-section. The grooves of the V-shaped troughs can stably accommodate the raw materials, preventing them from slipping during the rotation of the feed wheel and ensuring that a fixed amount of raw materials are carried out with each rotation. Simultaneously, the sloping sides of the V-shaped troughs guide the raw materials to fall quickly and evenly upon reaching the discharge port, further improving the uniformity of the raw material distribution and preventing localized accumulation or gaps. A feeding pipe 506 is located on the upper side of the storage box 501, away from the discharge hopper 502, with its upper end extending through the outer isolation cover 8. A second motor 504 provides stable rotational power to the feed wheel 503. By adjusting the motor speed, the feeding speed can be indirectly controlled. The faster the speed, the more raw materials are carried out by the feed troughs 505 per unit time, resulting in a larger feeding volume; conversely, a slower speed results in a smaller feeding volume, thus adapting to the different forage varieties' requirements for raw material distribution thickness and achieving flexible adjustment of the feeding volume.

[0029] See instruction manual attached Figure 3 As shown, the linear drive assembly 6 includes support frames 602 distributed on both sides of the storage box 501. Several track wheels 604 are rotatably mounted on the lower side of each support frame 602. The cultivation rack 1 is equipped with a track 603 for rolling support of the track wheels 604, and a hydraulic cylinder 601 for driving the storage box 501 to move horizontally and linearly. In practical applications, while the storage box 501 moves, the feeding wheel 503 of the spreading assembly 5 continuously rotates, and the feeding hopper 502 evenly feeds material into the cultivation tray below. Because the storage box 501 moves slowly along the length of the tray 1001, the outlet of the feeding hopper 502 can cover the entire length of the tray 1001. Combined with the design that the outlet of the feeding hopper 502 is the same width as the inner side of the tray 1001, the raw material is ultimately fully and evenly covered in both length and width directions within the cultivation tray, forming a cultivation substrate layer of uniform thickness. In addition, the linear drive assembly 6 drives the storage bin 501 to move, which can also play a role in evenly distributing materials inside the storage bin 501.

[0030] See instruction manual attached Figure 4 , Figure 6 and Figure 7As shown, the internal combing assembly 7 includes a guide rail 701 mounted on the upper side of the storage box 501. A lead screw 703 is rotatably mounted inside the guide rail 701, and a slider 702 is slidably mounted inside the guide rail 701. The slider 702 and the lead screw 703 are threadedly connected to each other. A second cylinder 704 is mounted inside the slider 702. The push rod head of the second cylinder 704 is fixedly connected to a lifting seat plate 707 with its head facing downward. Several combing rods 708 are mounted on the lower side of the lifting seat plate 707. Two guide rods 705 are symmetrically distributed on both sides of the second cylinder 704 with the cylinder as the center. The upper ends of the two guide rods 705 are slidably connected to the guide holes 706 opened at the corresponding positions of the slider 702, and the lower ends of the two guide rods 705 are fixedly connected to the upper side of the lifting seat plate 707. In practical applications, the combing rod 708 is directly inserted into the raw material in the storage bin 501. Through the combined action of vertical insertion and horizontal movement, it breaks up the clumps of raw material and stirs up the accumulated raw material. During the horizontal movement, the combing rod can break up the raw material that has clumped due to the dry and cold environment, and at the same time push the raw material accumulated on the edge and corner of the storage bin to the central feeding area, so as to avoid the raw material from being locally stuck or blocked in the storage bin, and ensure that the raw material can flow continuously and evenly to the hopper 502.

[0031] See instruction manual attached Figure 4 and Figure 10 As shown, a weighing component 11 is provided below the material transfer assembly 4 at the inlet 802. The weighing component 11 includes a third electric telescopic rod 1102. The third electric telescopic rod 1102 is fixedly installed on the lower side of the material transfer assembly 4 through a crossbeam 1101. The push rod head of the third electric telescopic rod 1102 faces upward and is connected to an electronic weighing device 1103.

[0032] The cultivation rack 1 has several parallel vertical beams 101, and the first conveyor 2 is set on the vertical beams 101. The number of first conveyors 2 is an odd number greater than or equal to 5.

[0033] Working principle of this invention: When using this livestock and forage cultivation device for arid and cold regions, the outer isolation cover 8 is installed on the outside of the cultivation rack 1 to keep it warm. The material is discharged through the outlet 801 and fed through the inlet 802. When neither material is being fed nor discharged, the outlet 801 and the inlet 802 are sealed by the opening and closing door structure 9, which greatly improves the heat preservation and moisture retention performance during cultivation in arid and cold regions. When the cultivation tray structure 10 is fed in, the door 901 is opened by the third cylinder 902 through the opening and closing door structure 9 at the inlet 802 on the outer isolation cover 8 outside the cultivation rack 1, and the cultivation tray structure 10 is fed into the outer isolation cover 8 through the material transfer component 4 at the inlet 802. In the material transfer assembly 4, the second electric telescopic rod 403 drives the second conveyor 401 to move under the support of the support roller 402. The lugs 404 ensure stable movement of the second conveyor 401. After the inlet 802 at the end of the second conveyor 401 receives the cultivation tray structure 10, the cultivation tray structure 10 is transferred to the material spreading position corresponding to the discharge hopper 502. The tray body 1001 of the cultivation tray structure 10 has protruding edges 1003 on both sides to facilitate transfer with the first conveyor 2 and the second conveyor 401, both of which are double-sided belt conveyors.

[0034] Then, the third electric telescopic rod 1102 of the weighing component 11 drives the electronic weigher 1103 to move upward until the electronic weigher 1103 lifts the cultivation tray structure 10 away from the second conveyor 401. The material spreading component 5 above the cultivation rack 1 begins to spread raw materials into the cultivation tray structure 10, and the amount of spreading is controlled by the electronic weigher 1103.

[0035] The material storage bin 501 of the material spreading assembly 5 is replenished with raw materials from outside the outer isolation cover 8 through the feeding pipe 506. The lower part of the material storage bin 501 is inclined towards the feeding hopper 502 on one side to facilitate the flow of raw materials into the feeding hopper 502. The second motor 504 drives the feeding wheel 503 inside the feeding hopper 502 to rotate. The V-shaped feeding groove 505 on the outer side of the feeding wheel 503 evenly feeds out the raw materials, and the length of the discharge port of the feeding hopper 502 is consistent with the inner width of the tray 1001 to ensure that the raw materials are evenly spread. At the same time, the hydraulic cylinder 601 in the linear drive assembly 6 drives the material storage bin 501 to move. The support frames 602 on both sides of the material storage bin 501 are equipped with rail wheels 604 on the lower side. With the cooperation of the rail wheels 604 and the rails 603 on the cultivation rack 1, the horizontal linear movement of the material storage bin 501 is realized, ensuring that the material is evenly spread to cover the cultivation tray structure 10.

[0036] During the material feeding process, the internal combing component 7 can comb the raw materials. The lead screw 703 in the guide rail 701 rotates, driving the slider 702 connected to it to move. The second cylinder 704 in the slider 702 drives the lifting seat plate 707 to descend. The guide rod 705 slides in the guide hole 706 to ensure the stable lifting of the lifting seat plate 707. The combing rod 708 on its lower side combs the raw materials in the cultivation tray to prevent the raw materials from clogging in the storage box 501, so that the raw materials can move towards the feeding hopper 502 for stable feeding.

[0037] After the material is laid out, the cultivation tray structure 10 is transported via the first conveyor 2 on the cultivation rack 1. When the cultivation tray structure 10 needs to change direction between different first conveyors 2, the material transfer reversing component 3 comes into play. The first electric telescopic rod 307 drives the lifting frame 301 to rise and fall. Two or more sets of support rods 305 on the lifting frame 301 can support the cultivation tray structure 10, and the limiting protrusions 306 on the support rods 305 prevent the cultivation tray structure 10 from slipping. At the same time, the first cylinder 302 drives the first motor 303 to move. The lever 304 on the first motor 303 cooperates with the protrusion 1002 on the lower side of the cultivation tray structure 10 to achieve push-pull positioning of the cultivation tray structure 10, completing the connection and reversing transmission between adjacent first conveyors 2. The vertical beam 101 on the cultivation rack 1 provides support for the first conveyors 2, and the number of first conveyors 2 is an odd number greater than or equal to 5 to meet the needs of multi-layer cultivation. Among them, the two adjacent first conveyors 2 have opposite transmission directions. If the first conveyors 2 are divided into two groups according to the transmission direction, the two material transfer reversing components 3 correspond to the two groups of first conveyors 2 respectively. The two or more sets of support rods 305 on the material transfer reversing components 3 correspond to two adjacent first conveyors 2 with the same transmission direction. When there are two sets of support rods 305, the first conveyor 2 has five evenly distributed vertically.

[0038] Once the forage cultivation is complete, the cultivation tray structure 10 is transported to the material transfer component 4 at the outlet 801 via the first conveyor 2 and the material transfer reversing component 3. Then, the opening and closing door structure 9 at the outlet 801 is opened to send the cultivation tray structure 10 out of the outer isolation cover 8, thus completing the entire forage cultivation process.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
