Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology and relates to a separation and harvesting device, specifically a hydroponic forage turning, separating, transporting and harvesting device. Background Technology

[0002] Forage grasses are widely cultivated in plant factories. Plant factories offer several advantages in hydroponic forage cultivation: First, they can control the environment to ensure crops grow in the most suitable range, meeting real-time market demands through automatic regulation, real-time monitoring, and year-round growth. Second, hydroponics effectively avoids soil pollution, reduces pests and diseases, promotes nutrient absorption by forage grasses, accelerates growth, and improves forage quality and yield.

[0003] The cultivation method in plant factories is mainly hydroponics. Although plant factories have many advantages, there are still many problems in establishing a commercial hydroponic forage plant factory. For example, the construction of the entire system requires various equipment, resulting in high operating costs; the degree of automation is low, requiring a large amount of manual intervention; and there is a lack of unified standards, which means poor compatibility of equipment and devices, leading to a significant increase in the corresponding production or purchase costs. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this invention is to provide a device for turning, separating, transporting, and harvesting hydroponic forage. This invention uses a turning platform to turn the seedling trays and relies on gravity to detach mature forage from the trays for transport and separation, offering advantages such as saving manpower and improving efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: I. A device for turning, separating, transporting, and harvesting hydroponic forage Transportation equipment used to transport hydroponic hay trays; A rotating mechanism installed in a transport mechanism is used to flip the hydroponic hay trays at the exit of the transport mechanism's conveyor belt; A drive mechanism installed on one side of the transport mechanism is used to control the rotating mechanism; Harvesting facilities are used to transfer and separate hydroponic forage and its seedling trays.

[0006] It also includes a traveling mechanism installed under the transport mechanism for moving the transport mechanism.

[0007] It also includes a distribution mechanism installed in the transport mechanism to tap the seedling trays, causing them to leave the conveyor belt on the harvesting mechanism from the side.

[0008] The transport mechanism includes multiple conveyor belt assemblies and mounting side plates. Multiple conveyor belt assemblies are installed between two mounting side plates. The multiple conveyor belt assemblies are arranged sequentially from bottom to top at intervals. In two adjacent conveyor belt assemblies, the conveyor belt outlet of one conveyor belt assembly exceeds the conveyor belt outlet of the conveyor belt assembly below it by a preset length. A corresponding rotating mechanism is installed at the conveyor belt outlet of each conveyor belt assembly.

[0009] The rotating mechanism includes multiple rotating components, each of which includes a platform, a buckle, a buckle link, and a spring. The platform is installed at the corresponding conveyor belt exit of the transport mechanism, and one side of the platform is connected to the drive mechanism. An installation strip is provided at the end of the platform away from the conveyor belt exit, and a guide groove is provided in the installation strip. The buckle link is installed in the guide groove and can slide along the guide groove. A spring fixing point is provided at the end of the buckle link near the drive mechanism, and a spring fixing point is also provided at the end of the installation strip near the drive mechanism. The spring is installed between the two spring fixing points. A limiting strip extending towards the conveyor belt exit is provided at the end of the buckle link away from the drive mechanism. The limiting strip passes through the guide groove and is set on the platform. The limiting strip is used to fix the hydroponic pasture tray.

[0010] The drive mechanism includes multiple flip motors, push rods, and sliding screw assemblies; the push rods are connected to the sliding screw assemblies, and each push rod is equipped with several control rods, each control rod cooperating with a corresponding rotating component; the output shaft of each flip motor is connected to the platform of each rotating component, and each push rod cooperates with the corresponding snap-fit ​​linkage of each rotating component.

[0013] The dispensing mechanism includes a motor and a striking rod; the motor drives the striking rod to strike the empty seedling trays.

[0014] II. A system for hydroponic forage grass The system includes the aforementioned hydroponic forage turning, separating, transporting, and harvesting device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention proposes a simple separation method. By flipping the mature forage grass and relying on its own weight, combined with the special conditions of hydroponics, the forage grass can be separated from the seedling tray on its own, and then harvested. This method has the advantages of saving manpower and being simple and efficient. 2. The walking mechanism designed in this invention includes auxiliary wheels, which can help the device move and facilitate the transfer of the device; 3. This invention designs a four-layer harvesting conveyor belt that can connect to the cultivation rack where seedling trays are placed, enabling simultaneous harvesting of multiple layers, which greatly improves harvesting efficiency. The ends of the conveyor belts of each layer have a certain length difference, ensuring that the seedling trays of each layer can be flipped and dropped normally without interfering with each other, thus improving the efficiency of separation and harvesting. 4. This invention uses a motor drive, and each layer can be controlled independently to meet different harvesting needs, which has the advantage of reducing energy consumption.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, the hydroponic forage turning, separating, transporting, and harvesting device proposed in this invention includes: Transport mechanism 2 is used to transport hydroponic hay trays; The rotating mechanism 3 installed in the transport mechanism 2 is used to flip the hydroponic hay trays at the conveyor belt outlet of the transport mechanism 2. The drive mechanism 1, installed on one side of the transport mechanism 2, is used to control the rotating mechanism 3; Harvesting unit 4 is used to transfer and separate hydroponic forage and its seedling trays.

[0019] The traveling mechanism 5, installed under the transport mechanism 2, is used to move the transport mechanism 2.

[0020] The distributing mechanism 6 is used to tap the seedling trays, causing them to leave the conveyor belt on the harvesting mechanism 4 from the side, thus further separating them from the barley straw.

[0021] like Figure 5 As shown, the transport mechanism 2 includes multiple conveyor belt assemblies and mounting side plates 105. Multiple conveyor belt assemblies are installed between two mounting side plates, arranged sequentially from bottom to top at intervals. In two adjacent conveyor belt assemblies, the conveyor belt outlet of one assembly extends beyond the conveyor belt outlet of the assembly below it by a predetermined length; that is, the conveyor belt outlets of the multiple assemblies protrude in a stepped manner from bottom to top, with a sufficient difference in length for the seedling trays to fall. Optionally, the conveyor belt inlets of the multiple conveyor belt assemblies are flush; a corresponding rotating mechanism 3 is installed at the conveyor belt outlet of each conveyor belt assembly. Each conveyor belt assembly includes a transport conveyor belt 201 and a conveyor belt motor 101. The height of the transport conveyor belt 201 is aligned with the forage seedling trays to be harvested. like Figure 6 and Figure 7As shown, the rotating mechanism 3 includes multiple rotating components, each of which includes a platform 301, a latch 302, a latching link 303, and a spring 304. Each platform 301 is rotatably mounted between two mounting side plates 105 at the corresponding conveyor belt outlet of each conveyor belt assembly of the transport mechanism 2 via protruding mounting posts on both sides. One side protruding connecting post of the platform 301 is coaxially connected to the output shaft of the tilting motor 102 of the drive mechanism 1. A mounting strip is provided at the end of the platform 301 away from the conveyor belt outlet, and a guide groove is provided in the mounting strip. The latching link 302... 3. Installed in the guide groove, which is parallel to the plane of the conveyor belt, the latching link 303 can slide along the guide groove. A spring fixing point 305 is provided at the end of the latching link 303 near the drive mechanism 1, and a spring fixing point 305 is also provided at the end of the mounting strip near the drive mechanism 1. A spring 304 is installed between the two spring fixing points 305. A limiting strip extending towards the conveyor belt outlet is provided at the end of the latching link 303 away from the drive mechanism 1. This limiting strip passes through the guide groove and is set on the platform 301, used to fix the hydroponic forage tray. The control end of the drive mechanism 1 (i.e., the push rod 103) passes through the mounting side plate 105 and contacts the latching link 303. The push rod 103 is used to push the latching link 303 to move within the guide groove, thereby adjusting the distance between the limiting strip and the mounting side plate 105 where the drive mechanism 1 is located. The hydroponic pasture tray is transported to platform 301 via conveyor belt. After the limiting strip and the side plate of platform 301 lock the hydroponic pasture tray, platform 301 is flipped over. The hydroponic pasture in the tray separates from the seedling tray by its own weight and falls onto the harvesting conveyor belt 401 of harvesting mechanism 4.

[0022] like Figure 2 As shown, the drive mechanism 1 includes multiple tilting motors 102, push rods 103, and a sliding screw assembly 104; the sliding screw assembly 104 is connected to the mounting side plate, and the push rods 103 are connected to the sliding screw assembly 104, as shown. Figure 3 As shown, the push rod 103 is equipped with several control rods. Each control rod passes through the mounting side plate 105 and engages with the corresponding snap-fit ​​connecting rod 303 of each rotating component, such as... Figure 4 As shown; specifically, two sliding screw assemblies 104 are arranged diagonally on the mounting side plate, and a push rod 103 is installed between the two sliding screw assemblies 104. The two ends of the push rod 103 are sleeved in the screw of the corresponding sliding screw assembly 104. The sliding screw assembly 104 drives the push rod 103 to move closer to or away from the mounting side plate, thereby locking and unlocking the latch 302 on the seedling tray. Multiple flip motors 102 are arranged in a stepped manner in the mounting side plate. The conveyor belt motor 101 is arranged vertically on one side, and the flip motors 102 are arranged in a stepped manner on the other side. The output shaft of each flip motor 102 is connected to the protruding connecting post of the platform 301 of each rotating assembly.

[0023] like Figure 8 As shown, the harvesting mechanism 4 includes a harvesting conveyor assembly installed below the rotating mechanism 3. The conveyor belt outlet of the harvesting conveyor assembly extends beyond the preset length of the conveyor belt outlet of the transport mechanism 2. The harvesting conveyor assembly includes a harvesting conveyor belt 401, a second motor, a fixed frame 402, and auxiliary wheels 403. One end of the harvesting conveyor belt 401 is located below the transport mechanism 2, and the other end extends outward and is located above the fixed frame 402. The auxiliary wheels 403 are located under the fixed frame 402 to assist in transferring the entire device. The rotating mechanism 3 flips and drops the seedling trays and barley straw, which eventually fall onto the harvesting conveyor belt 401. The barley straw falls into the factory's transport vehicle through the end of the harvesting conveyor belt 401, completing the harvesting of the barley straw. The auxiliary wheels 403 enable the harvesting mechanism 4 to move together with other structures to the next barley straw cultivation rack for harvesting from the next rack.

[0024] like Figure 10 As shown, the distributing mechanism 6 includes a distributing motor 601 and a striking rod 602; the distributing motor 601 is installed on the inner side of the mounting side plate 105, and the output shaft of the distributing motor 601 is connected to the striking rod 602. The striking rod 602 extends downward and is set close to the conveyor belt of the harvesting mechanism 4.

[0025] like Figure 9 As shown, the walking mechanism 5 includes a walking motor 501, walking wheels 502 and a chassis 503; the walking mechanism 5 moves, driving the auxiliary wheels 403 to move together.

[0026] The working process of this invention is as follows: The harvesting device moves to the cultivation rack via the walking mechanism 5 and auxiliary wheels 403. The conveyor belt 201 of the transport mechanism 2 connects to the mature forage and transports the forage to the platform 301 of the rotating mechanism 3. The platform 301 is rotated by the movement of the flipping motor 102, at which point the conveyor belt 201 stops moving. After rotating 180°, the mature forage falls onto the harvesting conveyor belt 401 due to gravity and can be loaded into other carts at the end. The sliding screw assembly 104 in the drive mechanism 1 drives the push rod 103 to move, pushing the buckle connecting rod 303. The connected buckle 302 is released, and the seedling tray falls from the platform 301 onto the harvesting conveyor belt 401. It can be transported to the end for loading, or the seedling tray can be manually removed midway or the empty seedling tray can be distributed away by the distribution mechanism 6. Finally, the separation of mature forage from seedling trays and the harvesting operation are completed.

[0027] Finally, it should be noted that the above embodiments and descriptions are only used to illustrate the technical solutions of the present invention and not to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the disclosure of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the protection scope of the claims of the present invention.
