It should be understood that the data used in this way can be interchanged where appropriate, so as to the embodiments of this application described herein.

[0019] like Figures 1-8 As shown, the present invention provides a test plot seeder, comprising a body 100 and a seeding device 200. The body 100 includes a mobile trolley 101 and a frame 102 that follows the mobile trolley 101, the frame 102 providing mounting support for the seeding device 200. Specifically, the mobile trolley 101 is a tracked vehicle, enabling the seeder to flexibly adapt to uneven terrain in the field; the seeding device 200 performs automatic seeding as it travels along the mobile trolley 101 via the frame 102.

[0020] It is worth noting that the mobile vehicle 101 includes a (tracked) travel module, a control module, and a navigation module. The control module reads the navigation data from the navigation module and controls the travel module to move along the path planned by the navigation data, thereby enabling the entire seeder to automatically navigate along the planned path and perform unmanned seeding operations.

[0021] In Example 1, the sowing device 200 includes a linear drive device 240, a movable seat 230, a seed box 210, and a seed metering device 260. The linear drive device 240 is mounted on the frame 102 and is used to drive the movable seat 230 to move linearly back and forth. The seed box 210 and the seed metering device 260 are both fixed on the movable seat 230, and the seed metering device 260 is connected to the seed box 210 through a seed metering pipe. Specifically, the moving path of the movable seat 230 forms an angle with the moving path of the moving trolley 101. That is, if the moving trolley 101 moves in the X direction, the movable seat 230 can drive the seed box 210 and the seed metering device 260 to perform multi-position sowing in the X and Y directions, effectively increasing the sowing width.

[0022] It is worth noting that the linear drive device 240 can be a linear motor structure or a motor lead screw structure, etc. The sowing speed of this utility model can be adapted to different crop row spacings by adjusting the driving speed of the linear drive device 240 and the seed metering speed of the seed metering device 260; the sowing row spacing can be adjusted by adjusting the unit forward distance of the moving trolley 101.

[0023] Furthermore, the method of using a linear drive device 240 to traction the seed box 210 and the seed metering device 260 to reciprocate and move the seeding row of the test plot, as listed in this example, is only one feasible solution. Multiple seed metering devices 260 can also be arranged in rows to achieve whole-row sowing, but this will not be exhaustive.

[0024] Example 2: The sowing device 200 includes a rotary drive device 250, a linear drive device 240, a movable seat 230, a seed box 210, a seed changing tube 220, and a seed metering device 260. The linear drive device 240 is mounted on the frame 102 and drives the movable seat 230 to move linearly back and forth. The seed box 210 is rotatably mounted on the movable seat 230, and the rotary drive device 250 drives the seed box 210 to rotate. The seed changing tube 220 is fixed through the movable seat 230 and extends coaxially into the seed box 210. The seed metering device 260 is connected to the bottom of the seed changing tube 220. Specifically, the movement path of the movable seat 230 forms an angle with the movement path of the movable trolley 101; that is, if the movable trolley 101 moves in the X direction, the movable seat 230 can drive the seed box 210 and the seed metering device 260 to perform multi-position sowing in both the X and Y directions.

[0025] It is worth noting that during the sowing process, according to the variety requirements of different sowing positions, the seed box 210 can be driven to rotate relative to the seed changing tube 220 by the rotation drive device 250. The inner cavity of the seed box 210 has a conical structure, and a partition 212 that can divide the conical inner cavity into at least one seed cavity 211 is detachably connected to the seed box 210 by a limiting component. The seed changing tube 220 is provided with an opening 221 to guide the seeds in the seed cavity 211 into the interior of the seed changing tube 220. Based on this, during the rotation of the seed box 210 relative to the seed changing tube 220, communication between different seed cavities 211 and the opening 221 can be achieved, thereby realizing automatic seed changing. The movable seat 230 moves from... Figure 1 Taking the movement from right to left as an example: After the moving seat 230 moves from the rightmost side of the linear drive device 240 to the leftmost side, completing one row of sowing, the seeding operation can be automatically performed by the drive of the rotary drive device 250. After the seed change, the seed metering device 260 removes excess seeds, the moving trolley 101 moves to change the sowing position, and the moving seat 230 moves from the leftmost side to the rightmost side to perform re-sowing after the seed change. The above process is repeated continuously to complete the automatic sowing operation of all sowing rows in the test plot.

[0026] In this example, as Figure 2As shown, the rotation drive device 250 includes a motor 251, a driving gear 252, and a driven gear 253. The motor 251 drives the driving gear 252 to rotate. The driving gear 252 meshes with the driven gear 253, which is sleeved and fixed outside the seed box 210. That is, the motor 251 drives the driving gear 252 to rotate, and the driving gear 252 drives the driven gear 253 to rotate, thereby realizing the rotation of the seed box 210 relative to the seed changing tube 220. The method of the motor 251 driving the seed box 210 to rotate, thereby achieving automatic seed changing, is only one feasible solution. Alternatively, a valve-type chamber can be used to store seeds of various varieties, and an electric push rod can be used to open and close the valve to achieve automatic seed changing. These are not exhaustive examples.

[0027] In addition, it should be noted that the limiting component in this example includes a first limiting member that limits the circumferential position of the partition member 212 and a second limiting member that limits the axial position of the partition member 212.

[0028] The first limiting member includes a protruding tooth 213 fixed on the surface of the seed box 210 and a groove 214 formed on the partition 212. When the partition 212 is connected to the seed box 210, the circumferential position of the partition 212 relative to the seed box 210 is limited by the mutual engagement of the protruding tooth 213 and the groove 214.

[0029] The second limiting member includes a retaining ring 215 disposed on the surface of the seed box 210 and a retaining groove 216 formed on the partition 212. The retaining ring 215 is an open ring and is rotatably mounted on the surface of the seed box 210. When the partition 212 is connected to the seed box 210, the circumferential position of the partition 212 relative to the seed box 210 is limited by the mutual engagement of the retaining ring 215 and the retaining groove 216.

[0030] Therefore, the limiting component allows for the quick assembly and disassembly of the partition 212, enabling the seed box 210's conical inner cavity to be divided into one or more seed chambers 211 according to sowing requirements. Specifically, the partition 212 is characterized as follows: Figure 6 and Figure 7The structure shown has a top connecting rod and a main plate and a sub-plate fixed to the bottom of the top connecting rod. A notch is formed between the main plate and the sub-plate so as to be snapped into the wall of the seed box 210. The inner end face of the main plate is sealed against the surface of the seed changing tube 220, and the outer end face of the main plate is sealed against the inner wall of the seed box 210, thereby ensuring that the various cavities 211 are independent of each other. Both the groove 214 and the slot 216 are provided on the sub-plate, and both the protruding tooth 213 and the retaining ring 215 are provided on the outer wall of the seed box 210. Thus, when the partition 212 is snapped onto the seed box 210, the retaining ring 215 of the open ring structure is rotated so that the opening of the retaining ring 215 aligns with the position where the partition 212 needs to be installed. Then, the partition 212 is snapped in, ensuring that the groove 214 and the protruding tooth 213 engage. After snapping, the retaining ring 215 is rotated to insert it into the slot 216, thereby completing the quick installation of the partition 212. Conversely, when disassembling the partition 212, the retaining ring 215 is rotated until its opening aligns with the partition 212, allowing the partition 212 to be disassembled along the axial direction of the seed box 210.
