For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0047] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a spray device for cultivating seedlings of crops comprises a box body 1, and a height adjustment mechanism 2 is fixedly arranged on the side wall of the box body 1. By setting the height adjustment mechanism 2, the entire layer of the seedling raising pot 6 can be moved to any height of the box body 1, and the relative height of each layer of the seedling raising pot 6 can be adjusted, which greatly reduces the labor intensity of the staff; a limiting component 3 is provided on the inner wall of the box body 1, and a longitudinal expansion mechanism 4 is fixedly arranged on the limiting component 3, and a sliding mounting seat 9 is arranged on the longitudinal expansion mechanism 4, and a transverse expansion mechanism 5 is arranged at the other end of the sliding mounting seat 9. By setting the limiting component 3, the longitudinal expansion mechanism 4 and the transverse expansion mechanism 5, the 6 layers of the seedling raising pots are automatically expanded after being pushed out of the box body 1, and the distance between the seedling raising pots 6 is enlarged, so that the seedlings can make full use of natural light and promote the rapid growth of the seedlings. When the external environment conditions are not enough, the seedling pot 6 is retracted into the box body 1, and the spacing between the seedling pots 6 becomes smaller, making full use of the internal space of the box body 1; the top of the sliding mounting seat 9 is fixedly connected with the seedling pot 6, and the front and rear of the box body 1 are both provided with openings 101. By setting the openings 101, it is convenient for the staff to observe the growth of the seedlings, and at the same time, it is convenient to put the seedlings into the seedling pot 6 or take out the seedlings in the seedling pot 6; a slide groove 102 is fixedly opened in the middle of the side wall of the box body 1, and a light belt installation groove 103, a water pipe installation groove 104 and a lifting limit groove 105 are also fixedly opened on the side wall of the box body 1.

[0048] like Figure 3 and Figure 4As shown, the height adjustment mechanism 2 includes a driving motor 201 and a screw 202, the driving motor 201 is fixedly connected to the top of the box body 1, the screw 202 is rotatably connected to the slide groove 102, the top of the screw 202 is fixedly connected to the output shaft of the driving motor 201, a screw block 205 is meshingly connected to the screw 202, the screw block 205 is slidingly connected to the slide groove 102, an electric push rod 204 is fixedly connected to the outside of the screw block 205, the push rod of the electric push rod 204 extends into the inside of the screw block 205, the push rod of the electric push rod 204 is fixedly connected to the drag block 203, and the inner center of the drag block 203 is fixedly connected to the unlocking push block 203A. The driving motor 201 drives the screw rod 202 to rotate, controls the lifting and lowering of the screw block 205, and the screw block 205 drives the electric push rod 204 and the drag block 203 to move to any height. The electric push rod 204 extends the push rod, drives the drag block 203 to extend forward and contact with the mounting platform 301, until the drag block 203 is completely stuck on the mounting platform 301, and the unlocking push block 203A also pushes out the push rod 308, so that the tooth block 308A is separated from the fixed tooth belt 105A, and the mounting platform 301 is unlocked from the locked state to the free state, and can be moved to any height driven by the drag block 203.

[0049] like Figure 7 , Figure 8 and Fig. 9 As shown, the limiting assembly 3 includes a mounting platform 301, which is slidably connected to the inner wall of the box body 1, and a through hole 301A is fixedly opened in the middle of the mounting platform 301. The through hole 301A cooperates with the drag block 203. When the drag block 203 is retracted under the control of the electric push rod 204, the drag block 203 can pass through the through hole 301A to avoid interference between the drag block 203 and the mounting platform 301 during the movement; a limiting boss 301B is fixedly connected to the outer side of the mounting platform 301, and the limiting boss 301B is slidably connected to the lifting limiting groove 105. The cooperation between 01B and the lifting limit groove 105 makes the mounting platform 301 more stable when sliding on the side wall of the box body 1, preventing the mounting platform 301 from tilting and causing the seedling pot 6 to overturn; a push rod 308 is provided inside the mounting platform 301, and the push rod 308 cooperates with the unlocking push block 203A. Tooth blocks 308A are fixedly provided on both sides of the push rod 308.

Under the elastic force of the second compression spring 309, the tooth block 308A extends and contacts and locks with the fixed tooth belt 105A, so that the mounting platform 301 can be fixed at any height of the box body 1. When the push rod 308 is squeezed, it will drive the tooth block 308A to squeeze the second compression spring 309, and the tooth block 308A will shrink and break away from the fixed tooth belt 105A, so that the mounting platform 301 can move freely on the side wall of the box body 1.

[0050] like Fig.13 , Fig.14 and Fig.15 As shown, a transverse limiting plate 302 is fixedly connected to the top of the mounting platform 301, and a wide opening is provided at one end of the transverse limiting plate 302, and a narrow opening is provided at the other end. By setting the transverse limiting plate 302, the transverse expansion mechanism 5 can be controlled to expand or contract, thereby controlling the transverse spacing of the seedling tank 6 to become larger or smaller; a fixing frame 303 is fixedly connected to one end of the mounting platform 301, and a slide groove 303A is fixedly provided at the upper and lower ends of the fixing frame 303, and a guide rod 303B is fixedly connected to the front end of the fixing frame 303. A slide seat 304 is slidably connected on 303, a compression spring 305 is fixedly connected to the front end of the slide seat 304, the other end of the compression spring 305 is fixedly connected to the guide rod 303B, a protrusion 304A is fixedly connected to the side wall of the slide seat 304, the front end top and the front end bottom of the slide seat 304 are both rotatably connected to a connecting rod 306, the other end of the connecting rod 306 is rotatably connected to a limiting pressure block 307, a pressure head 307A is fixedly provided on the limiting pressure block 307, and the limiting pressure block 307 is slidably connected to the slide groove 2 303A. When the protrusion 304A is pushed backward, the slide 304 slides backward and compresses the compression spring 1 305. Driven by the connecting rod 306, the limit pressure block 307 slides to the middle, and the pressure head 307A is pressed toward the center. The greater the distance the protrusion 304A moves backward, the greater the stroke of the pressure head 307A pressing toward the center. When the protrusion 304A loses its backward driving force, the compression spring 1 305 pushes the slide 304 to move forward. Driven by the connecting rod 306, the two groups of limit pressure blocks 307 move away from each other.

[0051] like Fig.16 , Fig.17 , Fig.18 and Fig.21 As shown, the longitudinal expansion mechanism 4 includes a slide rail 401, the outer wall of the slide rail 401 is slidably connected to the mounting platform 301, the front of the slide rail 401 is fixedly connected to a fixed cross bar 402, the top and bottom of the slide rail 401 are fixedly provided with fixed blocks 401A, the fixed blocks 401A cooperate with the protrusions 304A, the front end of the slide rail 401 is fixedly provided with a mounting hole 401B, the inner wall of the slide rail 401 is provided with a scissor-type telescopic joint 1 403, the scissor-type telescopic joint 1 403 includes a plurality of telescopic components 1 that are rotatably connected in sequence, the front end of the telescopic component 1 is rotatably connected to a pressure wheel, and the pressure wheel cooperates with the pressure head 307A; as shown Fig.19As shown, the telescopic assembly 1 includes a rotating rod 1 403A and a rotating rod 2 403B which are rotatably connected in the middle. The middle of the rotating rod 1 403A and the rotating rod 2 403B is rotatably connected with a transverse guide rod 404.

Fig. 20 As shown, the pull rod assembly 405 includes a large pull rod 405B, a small pull rod 405C and a tension spring 405A. Under the elastic force of the tension spring 405A, the large pull rod 405B and the small pull rod 405C maintain a tendency to approach each other, thereby pulling the transverse guide rod 404 closer to each other; the top of the large pull rod 405B and the top of the small pull rod 405C are both fixedly connected to the transverse guide rod 404, the top of the large pull rod 405B and the small pull rod 405C are slidably connected, one end of the tension spring 405A is fixedly connected to the large pull rod 405B, and the other end of the tension spring 405A is fixedly connected to the small pull rod 405C.

[0052] When the outside sunlight is sufficient, turn off the lighting strip 7, push the fixed cross bar 402, and make the slide rail 401 slide out of the box 1 on the mounting table 301. When the fixed block 401A on the slide rail 401 contacts the protrusion 304A, it drives the slide seat 304 to overcome the elastic force of the compression spring 305 and move backward. The pressure head 307A squeezes toward the middle, and the pressure head 307A squeezes the pressure wheel. As the slide rail 401 continues to move backward, the squeezing force on the pressure wheel gradually increases, so that the scissor-type telescopic joint 403 begins to unfold, and the extension The center distance of the expansion assembly 1 is getting larger and larger, driving the transverse guide rods 404 to move away from each other, and further driving the sliding mounting seats 9 to move away from each other, and the longitudinal spacing of the seedling pots 6 is gradually enlarged. When the fixed cross bar 402 is pulled to retract the slide rail 401, the fixed block 401A is disengaged from the protrusion 304A, and the pressure head 307A is also disengaged from the pressure wheel. The transverse guide rods 404 are moved closer to each other under the action of the pull rod assembly 405, and the scissor-type expansion joint 403 begins to shrink, and the longitudinal spacing of the seedling pots 6 is gradually reduced.

B, the middle parts of the rotating rod three 501A and the rotating rod four 501B are also rotatably connected to the longitudinal guide rod 503, the push rod assembly 502 includes a small push rod 502A, a large push rod 502C and a compression spring three 502B, the small push rod 502A and the large push rod 502C are both fixedly connected to the longitudinal guide rod 503, the small push rod 502A and the large push rod 502C are slidably connected, one end of the compression spring three 502B is fixedly connected to the large push rod 502C, and the other end of the compression spring three 502B is fixedly connected to the small push rod 502A.

[0054] When the slide rail 401 is pushed out of the box body 1, the sliding ball on the scissor-type expansion joint 501 contacts the wide side of the transverse limit plate 302. Under the elastic force of the push rod assembly 502, the scissor-type expansion joint 501 expands, driving the longitudinal guide rods 503 to move away from each other, and the transverse spacing of the seedling pots 6 is enlarged. When the slide rail 401 is pulled back into the box body 1, the sliding ball on the scissor-type expansion joint 501 contacts the narrow side of the transverse limit plate 302, the scissor-type expansion joint 501 contracts, the push rod assembly 502 is compressed to store elastic potential energy, the longitudinal guide rods 503 move closer to each other, and the transverse spacing of the seedling pots 6 is reduced.

When the seedling raising pot 6 of the whole layer is full of seedlings, the driving motor 201 controls the dragging block 203 to move the corresponding layer of the seedling raising pot 6, and the electric push rod 204 extends the push rod so that the dragging block 203 is inserted into the mounting platform 301 of the corresponding layer, driving the mounting platform 301 to be lifted to a predetermined height;

[0057] b: Control the electric push rod 204 to retract the push rod, push the block 203 to disengage from the mounting platform 301, and complete the placement of a layer of seedling pots 6. By controlling the drive motor 201 and the electric push rod 204, each layer of seedling pots 6 is placed one by one to a predetermined height;

[0058] c: The lighting strip 7 is used to provide light for the seedlings, and the sprinkler pipe 8 is used to provide water for the seedlings. When the external light conditions are sufficient, the fixed cross bar 402 is pushed so that the seedling raising pots 6 of this layer are pushed out of the box 1, and the natural light is fully utilized. Under the action of the longitudinal expansion mechanism 4 and the transverse expansion mechanism 5, the spacing between the seedling raising pots 6 is enlarged, and the photosynthesis of the seedlings is further promoted;

[0059] d: After the seedlings grow to a certain stage, the electric push rod 204 and the drive motor 201 are controlled to move the entire layer of seedling raising pots 6 to the bottom of the box body 1, so that the staff can transplant them conveniently.

[0060] Working principle:

[0061] 1. In the initial state, all the seedling raising pots 6 are piled at the bottom of the box body 1. The staff plant the seedlings in the seedling raising pots 6. When a whole layer is planted, the screw block 205 is lowered to the height of the seedling raising pot 6 layer full of seedlings by controlling the driving motor 201, and the electric push rod 204 is controlled to extend the push rod so that the push block 203 is pushed to the mounting platform 301. At the same time, the push block 203A is unlocked to push the push rod 308, so that the tooth block 308A is separated from the fixed tooth belt 105A. After the push block 203 drives the mounting platform 301 to rise to a predetermined height, the push block 203 is pushed to retract and separate from the mounting platform 301. The tooth block 308A contacts the fixed tooth belt 105A under the elastic force of the compression spring 2 309, and the mounting platform 301 is fixed. The seedling raising pot 6 of this layer is lifted to the height of the box body 1;

[0062] 2. By using this method, the layers of seedling raising pots 6 are gradually arranged on the box body 1, and the staff does not need to manually move the seedling raising pots 6 to a high position of the box body 1, which greatly reduces the work intensity of the staff;

[0063] 3. When the external light conditions are sufficient, turn off the lighting strip 7 to save energy, push the fixed crossbar 402 to push out the slide rail 401, and when the slide rail 401 slides on the mounting platform 301, the fixed block 401A pushes the protrusion 304A, so that the pressure head 307A squeezes the pressure wheel toward the middle, so that the scissor-type telescopic section 1 403 is unfolded, driving the transverse guide rod 404 to unfold, and the longitudinal spacing of the seedling tank 6 is enlarged. As the slide rail 401 moves toward the outside of the box body 1, the scissor-type telescopic section 2 501 is also unfolded under the push of the push rod assembly 502, and the transverse spacing of the seedling tank 6 is enlarged, thereby ensuring that the seedlings can fully photosynthesize;

[0064] 4. When the light condition is insufficient, the fixed cross bar 402 is pulled, the slide rail 401 is retracted, the scissor-type telescopic section 1 403 is contracted under the pulling of the pull rod assembly 405, and the scissor-type telescopic section 2 501 is contracted under the limiting action of the transverse limiting plate 302, thereby reducing the spacing of the seedling raising pots 6, so that the seedling raising pots 6 return to the inside of the box body 1, and light and water are supplemented with the help of the lighting strip 7 and the spray pipe 8;

[0065] 5. When the seedlings grow to a certain extent, the height adjustment mechanism 2 lowers the seedling raising pot 6 layer by layer to facilitate the staff to remove the seedlings, thus completing the seedling cultivation operation.

[0066] By setting a height adjustment mechanism 2, the present invention can move the entire layer of seedling pots 6 to any height of the box body 1, and adjust the relative height of each layer of seedling pots 6, which greatly reduces the labor intensity of the staff; by setting a limit component 3, a longitudinal expansion mechanism 4 and a transverse expansion mechanism 5, the seedling pots 6 layers are automatically unfolded after being pushed out of the box body 1, and the distance between the seedling pots 6 is increased, so that the seedlings can make full use of natural light and promote rapid growth of the seedlings. When the external environmental conditions are not enough, the seedling pots 6 are retracted into the box body 1, the distance between the seedling pots 6 becomes smaller, and the internal space of the box body 1 is fully utilized.
