[0024] Example 1

[0025] Reference Figure 1-3 This is the first embodiment of the present invention, providing a rice cultivation device. The cultivation device 1 includes a base 101, a fixing plate 102, a cultivation box 103, a support 104, a motor 105, and a lamp holder 106. The fixing plate 102 is fixedly connected to both sides of the top of the base 101. The cultivation box 103 is disposed inside the fixing plate 102. The support 104 is fixedly connected to both sides of the top of the base 101. The motor 105 is fixedly installed on the top of the inner wall of the support 104. The lamp holder 106 is fixedly connected to the output end of the motor 105. Adjustment mechanism 2; Adjustment mechanism 2 includes a T-slot 201, which is opened on the inner side of the fixed plate 102. An adjustment support plate 202 is movably connected to the inner wall of the T-slot 201. Auxiliary support plates 203 are fixedly connected to both the front and rear sides of the adjustment support plate 202. The incubation box 103 is located on top of the adjustment support plate 202 and the auxiliary support plates 203. A limit component 204 is fixedly connected to the outer side of the top of the adjustment support plate 202.

[0026] Locking mechanism 3; Locking mechanism 3 is fixedly installed at the bottom of auxiliary support plate 203.

[0027] Specifically, the adjustment mechanism 2 makes it easier to adjust the spacing of the cultivation box 103, eliminating the need for repeated manual alignment and insertion into the slots, which greatly saves manpower and time and significantly improves the efficiency of cultivation work; the locking mechanism 3 ensures the stability of the position of the cultivation box 103 after adjustment, preventing position movement due to external factors or its own gravity, and ensuring the stability and reliability of cultivation work.

[0028] Furthermore, when it is necessary to adjust the spacing of the incubation box 103, the operator first moves the lever 306 inward. This operation causes the locking seat 303 in the locking mechanism 3 to slide within the slide groove 302, compressing the spring 305 and disengaging the locking seat 303 from the locking groove 304, thereby releasing the lock on the adjusting support plate 202 in the adjusting mechanism 2. At this time, the adjusting support plate 202 can move freely within the T-slot 201 inside the fixed plate 102. When the operator pushes the adjusting support plate 202, since the adjusting support plate 202 is fixedly connected to the auxiliary support plate 203, and the incubation box 103 is placed between the adjusting support plate 202 and the auxiliary support plate 203, the operator can adjust the spacing of the incubation box 103. 3. At the top, the adjusting support plate 202 will drive the auxiliary support plate 203 and the incubation box 103 to move together in the T-slot 201. During the movement, the measuring block 6 on the auxiliary support plate 203 will move outside the scale groove 7 of the fixed plate 102, which makes it convenient for the operator to intuitively judge the adjustment distance. When the adjustment is in the appropriate position, the lever 306 is released, the spring 305 returns to its deformation, and pushes the locking seat 303 to re-insert into the corresponding locking groove 304 to lock the adjusting support plate 202, thereby fixing the position of the incubation box 103 and completing the entire adjustment and locking process, realizing the flexible adjustment and stable fixation of the spacing of the incubation box 103.

[0029] Example 2

[0030] The second embodiment of this utility model provides a rice planting and cultivation device, including an adjusting mechanism 2. The adjusting mechanism 2 includes a T-shaped groove 201, which is formed inside a fixed plate 102. An adjusting support plate 202 is movably connected to the inner wall of the T-shaped groove 201. Auxiliary support plates 203 are fixedly connected to both the front and rear sides of the adjusting support plate 202. A cultivation box 103 is located on top of the adjusting support plate 202 and the auxiliary support plates 203. A limiting component 204 is fixedly connected to the outer side of the top of the adjusting support plate 202. The limiting component 204 includes a limiting plug 2041, which is fixedly connected to the adjusting support plate 202. On the outer side of the top of the support plate 202, a limiting slot 2042 is provided at the bottom of the incubation box 103. The limiting block 2041 is inserted into the inner wall of the limiting slot 2042. The front and rear sides of both sides of the auxiliary support plate 203 are movably inlaid with ball bearings 4. The inner sides of the fixed plate 102 are provided with movable grooves 5. The surface of the ball bearings 4 is movably connected to the inner wall of the movable grooves 5. The front and rear sides of the auxiliary support plate 203 are fixedly connected with measuring blocks 6. The fixed plate 102 is provided with scale grooves 7 on both sides. The scale grooves 7 are arranged in several groups and are evenly distributed. The measuring blocks 6 are located outside the scale grooves 7.

[0031] Specifically, the spacing of the cultivation box 103 can be easily and quickly adjusted through the adjustment mechanism 2, which greatly saves manpower and time costs, significantly improves the efficiency of cultivation work, and greatly enhances the practicality of the cultivation device 1.

[0032] Furthermore, when it is necessary to adjust the spacing of the incubation box 103, the adjusting support plate 202 is pushed. Since the auxiliary support plates 203 are fixedly connected to both the front and rear sides of the adjusting support plate 202, and the incubation box 103 is located on top of the adjusting support plate 202 and the auxiliary support plates 203, the adjusting support plate 202 will drive the auxiliary support plates 203 and the incubation box 103 to move together in the T-slot 201. At the same time, the measuring blocks 6 fixedly connected to both the front and rear sides of the auxiliary support plate 203 will move outside the scale grooves 7 opened on both sides of the fixed plate 102. The operator can intuitively judge the adjustment distance according to the scale grooves 7. Moreover, the friction between the auxiliary support plate 203 and the fixed plate 102 can be reduced by the ball bearings 4 and the sliding grooves 302, which improves the smoothness of the adjustment of the auxiliary support plate 203.

[0033] Example 3

[0034] The second embodiment of this utility model provides a rice planting and cultivation device. The locking mechanism 3 includes a mounting plate 301, which is fixedly connected to the bottom of the adjusting support plate 202. A sliding groove 302 is provided at the bottom of the mounting plate 301. A locking seat 303 is slidably connected to the inner wall of the sliding groove 302. A locking groove 304 is provided on the inner side of the fixing plate 102. The number of locking grooves 304 is arranged in several groups and is evenly distributed. The outer side of the locking seat 303 is inserted into the inner wall of the locking groove 304. A spring 305 is provided inside the sliding groove 302. One end of the spring 305 is fixedly connected to the inner side of the inner wall of the sliding groove 302, and the other end of the spring 305 is fixedly connected to the inner side of the locking seat 303. A toggle rod 306 is fixedly connected to the bottom of the locking seat 303. A protective sleeve 307 is fixedly sleeved on the surface of the toggle rod 306.

[0035] Specifically, the locking mechanism 3 can securely lock the adjusted position of the cultivation box 103, ensuring that the cultivation box 103 will not move due to external factors or its own gravity during the cultivation process, thus ensuring the stability and reliability of the cultivation work. At the same time, it works in conjunction with the adjustment mechanism 2 to make the spacing adjustment and fixing operation of the cultivation box 103 more convenient and efficient, further improving the performance of the entire cultivation device 1.

[0036] Furthermore, in the initial state, under the action of the spring 305, the outer side of the locking seat 303 is inserted into the inner wall of the locking groove 304, thereby fixing the adjusting support plate 202 in the current position and ensuring the stability of the incubation box 103. When it is necessary to adjust the spacing of the incubation box 103, the operator moves the lever 306 inward, causing the locking seat 303 to slide in the slide groove 302, compressing the spring 305, causing the locking seat 303 to disengage from the locking groove 304, and releasing the locking of the adjusting support plate 202. At this time, the adjusting support plate 202 can move freely. After adjusting to the appropriate position, the lever 306 is released, the spring 305 returns to its deformation, pushes the locking seat 303 to re-insert into the corresponding locking groove 304, and locks the adjusting support plate 202 again, thereby fixing the position of the incubation box 103, realizing reliable locking and flexible adjustment of the position of the incubation box 103.

[0037] Working principle: In the initial state, the locking seat 303 in the locking mechanism 3, under the elastic force of the spring 305, engages with the locking groove 304 on the inner side of the fixing plate 102, thereby firmly locking the adjusting support plate 202 in the current position. This ensures that the cultivation box 103 is stably placed on top of the adjusting support plate 202 and the auxiliary support plate 203, meeting the basic requirements for rice seedling cultivation. When it is necessary to adjust the spacing of the cultivation boxes 103, the operator first moves the actuating rod 306 at the bottom of the locking seat 303 inward. The actuating rod 306 drives the locking seat 303 to move inward during installation. The plate 301 slides within the groove 302 at its bottom. During this process, the spring 305 is compressed, causing the locking seat 303 to disengage from the locking groove 304, thereby releasing the lock on the adjusting support plate 202. At this point, the adjusting support plate 202 is freed from its restriction and can move freely within the T-groove 201 inside the fixed plate 102. When the operator pushes the adjusting support plate 202, since the adjusting support plate 202 is fixedly connected to the auxiliary support plate 203 and the incubation box 103 is placed on top of both, the adjusting support plate 202 will cause the auxiliary support plate 203 and the incubation box 103 to move together in the T-groove 201. During the movement, the measuring blocks 6 on the front and rear sides of the auxiliary support plate 203 will move synchronously outside the scale grooves 7 on both sides of the fixed plate 102. The operator can visually judge the adjustment distance based on the scale grooves 7 to achieve precise adjustment. When the spacing of the incubation boxes 103 is adjusted to the appropriate position, the operator releases the lever 306, the compressed spring 305 recovers its deformation, and the resulting elastic force pushes the locking seat 303 back into the corresponding locking groove 304, locking the adjustment support plate 202 again, thereby fixing the position of the incubation box 103 and completing the entire process. In addition to the adjustment and locking process, the ball bearings 4 embedded on both sides of the auxiliary support plate 203 cooperate with the movable groove 5 on the inner side of the fixed plate 102 to effectively reduce the friction between the auxiliary support plate 203 and the fixed plate 102 during the adjustment process, making the adjustment operation smoother. The limiting block 2041 on the outer side of the top of the adjustment support plate 202 is inserted into the limiting slot 2042 at the bottom of the incubation box 103, which can initially limit the incubation box 103 and prevent the incubation box 103 from shaking during the adjustment or incubation process, further ensuring the stability of the device operation.

[0038] In summary, by setting the adjustment mechanism 2 and the locking mechanism 3, the spacing adjustment of the culture box 103 is made more convenient, eliminating the need for repeated manual alignment and insertion into the slots, which greatly saves manpower and time and significantly improves the efficiency of the cultivation work. The locking mechanism 3 ensures the stability of the position of the culture box 103 after adjustment, preventing position movement due to external factors or its own gravity, thus ensuring the stability and reliability of the cultivation work. It solves the problem that when it is necessary to frequently adjust the spacing of the culture boxes or install multiple culture boxes, the process of manually aligning and inserting into the slots is extremely cumbersome and inconvenient for adjusting the culture boxes, which not only consumes a lot of manpower and time but also seriously affects the efficiency of the cultivation work, thus achieving the effect of easy adjustment.
