[0002] The ability to promptly detect the actual operational performance and working status of new agricultural equipment and identify its shortcomings is crucial for accelerating the optimization and improvement research of new agricultural equipment. However, the growth cycle of crops is greatly affected by factors such as region and climate, and the time that crops spend in different growth stages is relatively short. Therefore, the time suitable for field testing and inspection of corresponding new agricultural equipment is very limited. Thus, the ability to provide a field operation environment for testing new agricultural equipment in a timely manner is very important for accelerating the research and development of new agricultural equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a height-adjustable and rotating experimental platform, which improves the problem that the test speed of a straight soil trough experimental platform cannot be continuously and uniformly operated due to the influence of distance.

The location allows for the mounting of testing equipment, and the rotating tray can store the testing system equipment. The drive shaft housing of drive motor one is fixedly connected to the upper flange of the height adjuster rod via a connecting platform. The height adjuster is fixedly connected to the support base, which is hollow inside, allowing the height adjuster rod to extend and retract freely within the support base. The outer wall of the bearing gear is fixedly connected to the soil trough, and the inner wall of the bearing gear is fixedly connected to the base.

Drive motor two is fixedly connected to the base, and the drive wheel of drive motor two is connected to the drive outer wall of the bearing gear. The start / stop, rotation direction, and rotation speed of drive motor one and drive motor two are controlled by a controller.

[0005] In this case, the height-adjustable and rotatable experimental platform adopts a circular structure; the mounting rod is fixed together with the rotating support; the height adjuster supports the first drive motor by lifting the platform, thereby adjusting the height of the platform; the first drive motor, the height adjuster, the soil trough, the bearing gear, and the base are collinear; the drive wheel of the second drive motor and the drive outer wall of the bearing gear can mesh with each other or be connected by a pulley; the support roller and the bearing gear jointly support the soil trough; the controller communicates with the first and second drive motors via a signal line or wireless communication; the front end of the first and second drive motors can be equipped with a gearbox, and the two drive motors can be controlled by one controller or by separate controllers.

[0011] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A height-adjustable and rotatable experimental platform is mainly composed of a hanging rod 1, a rotating support 2, a first drive motor 3, a height adjuster 4, a soil trough 5, a bearing gear 6, a second drive motor 7, supporting rollers 8, a base 9, and a controller 10.

[0012] In this embodiment, weed identification is used as a reference. The experimental platform is a circular soil trough 5 with a radius of 1 meter and a height of 0.3 meters. The drive motor 3 is equipped with a gearbox, and the height adjuster 4 is a hand-cranked screw lift.

[0013] The support platform, consisting of the mounting rod 1 and the rotating tray 2, can rotate in both directions and move up and down. The soil trough 5 can also rotate in both directions. The support platform and the soil trough 5 can rotate independently or simultaneously in the same or opposite directions. The mounting rod 1 and the rotating tray 2 are fixedly installed to form the support platform, which is fixedly connected to the drive shaft inside the gearbox of the drive motor 3. Under the action of the drive motor 3, the support platform can rotate in both directions. The test device can be mounted on the mounting rod 1, and the rotating tray 2 can store the test system device. The gearbox housing of the drive motor 3 and the upper flange of the height adjuster 4 are fixedly connected through the platform 12. The height adjuster 4 is fixedly connected to the support base 11, which is hollow inside, and the adjusting rod of the height adjuster 4 can freely extend and retract inside the support base 11. The outer wall of the bearing gear 6 is fixedly connected to the soil trough 5, and the inner wall of the bearing gear 6 is fixedly connected to the base 9. The support rollers 8 are evenly distributed around the circumference. Distributed on the base 9 and fixedly connected to the base 9, the rollers of the supporting rollers 8 are pressed against the soil trough 5; the second drive motor 7 is fixedly connected to the base 9, and the drive wheel of the second drive motor 7 is connected to the drive outer wall of the bearing gear 6; the start, stop, rotation direction, and rotation speed of the first drive motor 3 and the second drive motor 7 are controlled by the controller 10; the height adjuster 4 lifts and supports the first drive motor 3 through the platform 12 to realize the height adjustment of the support platform; the first drive motor 3, the height adjuster 4, the soil trough 5, the bearing gear 6, and the base 9 are collinear; the drive wheel of the second drive motor 7 meshes with the drive outer wall of the bearing gear 6; the supporting rollers 8 and the bearing gear 6 jointly support the soil trough 5; the first drive motor 3 is equipped with a gearbox.

[0014] During operation, the mounting rod 1 and the rotating tray 2 are fixed together. The drive motor 3 drives the mounting rod 1 and the rotating tray 2 to rotate together around the center through the front gearbox. The speed is controlled by the controller 10. The rotating tray 2 holds the control board, microcomputer and other equipment required for weed identification. The mounting rod 1 is fixed with a camera. The height of the support platform is adjusted by the rocker arm of the screw jack to meet the test requirements of different heights for weed identification accuracy. The controller 10 regulates the drive motor 7, so that the motor gear drives the bearing gear 6 to rotate, thereby driving the circular soil trough 5 to rotate. The mounting rod 1 and the rotating tray 2 can rotate independently in the forward and reverse directions, and the soil trough 5 can also rotate independently in the forward and reverse directions. They can also rotate simultaneously in the same direction or in opposite directions to meet the test requirements of different speeds.

[0015] Although the inventive concept and examples have been described in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can be made to the invention without departing from the scope defined by the claims, and such improvements and modifications should fall within the protection scope of the invention.
