[0027] When the height of the culture tray 107 needs to be adjusted, the motor 301 is started, and the motor 301 drives the worm 302 connected to its output end to rotate. The rotation of the worm 302 drives the worm wheel 303 meshing with it to rotate. The rotation of the worm wheel 303 drives the screw rod 304 fixedly connected to the inner wall to rotate. The rotation of the screw rod 304 drives several lifting plates 305 threadedly connected to it to move up and down. The movement of the lifting plate 305 drives the culture tray 107 slidingly connected to the inner wall to move, so as to adjust the height of the culture tray 107. At the same time, the connecting rod 1 306, the connecting rod 2 307, the connecting rod 308, the connecting rod 4 309, and the connecting rod 5 310 can make the distance between the lifting plates 305 equal when the lifting plates 305 are lifted or lowered. The sliding rod 311 makes the lifting plates 305 more stable when moving up and down, so that the device can adapt to the needs of seeds at different growth stages.

[0028] like Figure 4 , Figure 5 , Figure 6As shown, the fixing assembly 4 includes a plurality of connecting plates 401, and the rear side walls of the plurality of connecting plates 401 are respectively fixedly connected to the front inner walls of a plurality of lifting plates 305 which are equidistantly distributed up and down, the front side walls of the connecting plates 401 are fixedly connected to a fixing frame 402, the inner wall of the fixing frame 402 is slidably connected to a slide plate 403 through a set slide groove, a groove 404 is provided on the top of the slide plate 403, a fixing rod 405 is fixedly connected to the top wall of the connecting plate 401, an adjusting rod 406 is rotatably connected to the outer wall of the fixing rod 405, a cylindrical sliding rod 408 is fixedly connected to the front end of the adjusting rod 406, the outer wall of the cylindrical sliding rod 408 is slidably connected to the inner wall of the groove 404, the rear side wall of the slide plate 403 is fixedly connected to a spring 407 fixedly connected to the front side wall of the connecting plate 401, and the front side wall of the slide plate 403 is fixedly connected to a moving rod 409 which penetrates through the front side wall of the fixing frame 402.

[0029] like Figure 4 , Figure 5 , Figure 6 As shown, the fixing component 4 also includes a protrusion 411, the top of the protrusion 411 passes through the top of the groove opened at the bottom of the fixing frame 402 and is fixedly connected to the bottom of the slide plate 403, the bottom of the protrusion 411 is provided with a rectangular groove and the left and right inner walls of the rectangular groove are provided with inclined grooves 412, the bottom of the fixing frame 402 is fixedly connected with two left-right symmetrical lower fixing rods 413, the opposite side walls of the two lower fixing rods 413 are fixedly connected with a rotating shaft 414, the outer wall of the rotating shaft 414 is rotatably connected with an L-shaped rod 415, the upper end of the fixing rod 1 405 is fixedly connected with a cylindrical slider 2 416, the outer wall of the cylindrical slider 2 416 is slidably connected to the inner wall of the inclined groove 412, and the front end of the L-shaped rod 415 is clamped with a card plate 410 fixedly connected to the bottom of the culture dish 107.

[0030] When it is necessary to sow seeds into the culture tray 107, the culture tray 107 can be quickly and effectively taken out through the set fixing component 4 to facilitate sowing. When in use, the culture tray 107 is pressed by the set handle 108 to move the culture tray 107 backward. At this time, the rear side wall of the culture tray 107 will contact the front side wall of the moving rod 409, thereby pushing the moving rod 409 to move backward. The moving rod 409 moves to drive the slide plate 403 fixedly connected thereto to move backward. Since a groove 404 is provided on the top of the slide plate 403, the slide plate 403 drives the cylindrical slide bar 408 slidably connected to the inner wall of the groove 404 to move to the rear side of the groove 404 when moving. The slide plate 403 drives the protrusion 411 fixedly connected thereto to move while moving. The movement of the protrusion 411 causes the inclined groove 412 arranged on its side wall to drive the cylindrical slider 416 to slide. The sliding of the cylindrical slider 416 drives the L-shaped rod 415 fixedly connected thereto to rotate. The rotation of the L-shaped rod 415 will release the clamping relationship with the clamping plate 410, so that the culture tray 107 can be released. When the culture tray 107 needs to be clamped again, the culture tray 107 is pushed backward again. The culture tray 107 drives the moving rod 409 to move. Under the elastic force of the spring 407, the cylindrical slide rod 408 is further driven to slide to the front side of the groove 404, driving the L-shaped rod 415 to clamp the clamping plate 410, so that the culture tray can be disassembled and replaced better and faster, which is convenient for daily management operations such as seed sowing and fertilizing.

[0031] The working principle of this new agricultural seed cultivation tray is described in detail below.

[0032] like Figure 1-6 As shown, when the seeds on the culture tray 107 need to be watered, water or nutrient solution can be first added to the interior of the water tank 106 through the water inlet arranged at the top of the water tank 106, and then the water pump 201 is started. The water pump 201 pumps the water inside the water tank 106 into the water pipe 204 through the water inlet pipe 202 and the water outlet pipe 203, and then the water is sprayed out by the nozzle 205 arranged on the surface of the water pipe 204 to achieve watering of the seeds.

[0033] When the height of the culture tray 107 needs to be adjusted, the motor 301 is started, and the motor 301 drives the worm 302 connected to its output end to rotate. The rotation of the worm 302 drives the worm wheel 303 meshing with it to rotate. The rotation of the worm wheel 303 drives the screw rod 304 fixedly connected to the inner wall to rotate. The rotation of the screw rod 304 drives several lifting plates 305 threadedly connected to it to move up and down. The movement of the lifting plate 305 drives the culture tray 107 slidingly connected to the inner wall to move, so as to adjust the height of the culture tray 107. At the same time, the connecting rod 1 306, the connecting rod 2 307, the connecting rod 308, the connecting rod 4 309, and the connecting rod 5 310 can make the distance between the lifting plates 305 equal when the lifting plates 305 are lifted or lowered. The sliding rod 311 makes the lifting plates 305 more stable when moving up and down, so that the device can adapt to the needs of seeds at different growth stages.

[0034] When it is necessary to sow seeds into the culture tray 107, the culture tray 107 can be quickly and effectively taken out through the set fixing component 4 to facilitate sowing. When in use, the culture tray 107 is pressed by the set handle 108 to move the culture tray 107 backward. At this time, the rear side wall of the culture tray 107 will contact the front side wall of the moving rod 409, thereby pushing the moving rod 409 to move backward. The moving rod 409 moves to drive the slide plate 403 fixedly connected thereto to move backward. Since a groove 404 is provided on the top of the slide plate 403, the slide plate 403 drives the cylindrical slide bar 408 slidably connected to the inner wall of the groove 404 to move to the rear side of the groove 404 when moving. The slide plate 403 drives the protrusion 411 fixedly connected thereto to move while moving. The movement of the protrusion 411 causes the inclined groove 412 arranged on its side wall to drive the cylindrical slider 416 to slide. The sliding of the cylindrical slider 416 drives the L-shaped rod 415 fixedly connected thereto to rotate. The rotation of the L-shaped rod 415 will release the clamping relationship with the clamping plate 410, so that the culture tray 107 can be released. When the culture tray 107 needs to be clamped again, the culture tray 107 is pushed backward again. The culture tray 107 drives the moving rod 409 to move. Under the elastic force of the spring 407, the cylindrical slide rod 408 is further driven to slide to the front side of the groove 404, driving the L-shaped rod 415 to clamp the clamping plate 410, so that the culture tray can be disassembled and replaced better and faster, which is convenient for daily management operations such as seed sowing and fertilizing.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
