It has a wide range of applications, covering forestry, agriculture, horticulture and other fields. This facility provides a suitable environment for plant growth and is usually equipped with temperature, humidity and light control functions to ensure that seeds can germinate smoothly and cultivate healthy seedlings for subsequent transplanting or transplanting. Seedlings are usually placed in nursery pots, which are placed on nursery beds. Since the nursery pots contain soil, they are heavy. If large-scale cultivation is carried out, it will be too heavy to rely on manual transportation of the nursery pots to the nursery bed.

When the movable plate 24 in the present application moves downward, it will push the gas in the recovery block 21 from the inlet groove into the connecting groove 26, and then blow it obliquely from the air outlet holes 27 onto the bristles 23, thereby blowing away the dirt on the bristles 23 to achieve the effect of cleaning the bristles 23.

[0028] Embodiment 2: Figure 6 to Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the inner wall of the loading plate 4 is slidably connected with a pair of limit plates 28, and the side of the limit plate 28 away from the inner wall of the loading plate 4 is fixedly connected with a group of rollers 29, and the loading plate 4 is provided with a pushing component for pushing the limit plate 28; in the present application, after the seedling basin is placed on the loading plate 4, the limit plate 28 can be pushed with the help of the pushing component, so that the roller 29 contacts the seedling basin, and at this time the seedling basin will be limited by the thrust to prevent the seedling basin from shaking, and when the seedlings are pushed for loading, the roller 29 can assist the seedling basin to move.

[0029] The pushing assembly includes a rectangular plate 30 fixedly connected to the inner wall of the loading plate 4, a slide plate 31 slidably connected inside the rectangular plate 30, the side of the slide plate 31 away from the rectangular plate 30 is fixedly connected to the limiting plate 28, and a group of third springs are fixedly connected between the side of the slide plate 31 away from the limiting plate 28 and the inner wall of the rectangular plate 30; the limiting plate 28 in the present application can use the force of the third spring to push the slide plate 31, so that the limiting plate 28 increases the thrust on the seedling pot, thereby limiting the seedling pot on the loading plate 4.

[0030] The lifting device 4 is a kind of lifting device which is used to lift the load plate 4 and put it on the lifting platform 8. The lifting device 4 is a kind of lifting device which is used to lift the load plate 4 and put it on the lifting platform 8. The seedling tray on the material plate 4 is transferred to the multi-layer seedling bed. The multi-layer seedling bed can be flexibly loaded with materials through the above-mentioned mechanism, and the loading plate 4 in the present application is also arranged in multiple layers, which can store more seedling trays; when the rotating shaft 7 in the present application needs to be rotated, the connecting ring 9 can be pulled, so that the connecting ring 9 drives the round rod 10 to disengage from the slot 11, and then the rotating shaft 7 can be rotated to make the round rod 10 contact with the second positioning plate 14. At this time, the push plate 8 will be arranged horizontally, and the round rod 10 will be engaged with the slot 11 under the action of the first spring pushing the connecting ring 9. When the push plate 8 needs to be set vertically, the round rod 10 is disengaged from the slot 11 again, and then the rotating shaft 7 is rotated to make the round rod 10 contact with the first positioning plate 13. At this time, the push plate 8 on the rotating shaft 7 will be arranged vertically, and the above-mentioned mechanism can be used to fix the push plate 8 after it is rotated, so as to facilitate the use of the push plate 8.

[0031] When the rotating shaft 7 in the present application needs to be rotated, the round rod 10 is first pulled out of the clamping groove 11, and the elastic plate 16 can temporarily limit the rotating shaft 7, and then the inflation component can inflate the elastic plate 16 on the corresponding rotating shaft 7 that needs to be rotated. At this time, the elastic plate 16 will expand, thereby pushing the driving plate 15, so that the driving plate 15 drives the rotating shaft 7 to rotate, and then the push plate 8 is placed horizontally.

At this time, the elastic plate 16 will drive the recovery, thereby driving the rotating shaft 7 to reset; in the present application, when it is necessary to When the top rotating shaft 7 is to be rotated, the control valve on the connecting pipe 18 except the one connected to the top elastic plate 16 can be closed, and then the connecting plate 6 can be controlled by means of the electric guide rail 5 to squeeze the elastic block 20, so that the gas in the elastic block 20 enters the elastic plate 16 from the connecting pipe 18, thereby allowing the elastic plate 16 to expand and push the rotating shaft 7 to rotate. Then, after the clamping rod is clamped with the clamping slot 11, the rotating shaft 7 will be limited. Later, when the connecting plate 6 is away from the elastic block 20, due to the limitation of the rotating shaft 7, the gas in the elastic plate 16 will not flow back from the connecting pipe 18 to the elastic block 20. After the clamping rod is detached from the clamping slot 11, the elastic block 20 loses the squeezing of the connecting plate 6, and the gas in the elastic plate 16 will return to the elastic block 20, so that the elastic block 20 and the elastic plate 16 are reset.

[0032] When the seedling pot in the present application is on the loading plate 4, it is inevitable that some soil will fall on the loading plate 4. At this time, while the push plate 8 pushes the seedling pot, it can also push the soil on the loading plate 4, so that the soil enters the recovery block 21 from the feed trough 22 to be recovered. At the same time, the bristles 23 can clean the bottom surface of the seedling pot passing through, clean the soil at the bottom of the seedling pot, and then enter the recovery block 21 from the feed trough 22; when the push plate 8 in the present application moves to the top of the recovery block 21, the magnetic block 25 will attract the moving plate 24 to move upward, and then after the moving plate 24 is reset, the moving plate 24 will be reset under the pull of the second spring. At this time, the feed trough 22 It will inhale air, thereby sucking the soil around the feed trough 22 into the recovery block 21 to improve the effect of cleaning the soil. At the same time, when the movable plate 24 is reset, due to the action of the second spring, it will shake repeatedly, so that the soil above the movable plate 24 is more evenly distributed on the movable plate 24 under the action of shaking, thereby increasing the recovery volume of the soil by the recovery block 21; when the movable plate 24 in the present application moves downward, it will push the gas in the recovery block 21 from the feed trough into the connecting groove 26, and then blow it obliquely from the air outlet 27 onto the bristles 23, thereby blowing off the soil on the bristles 23 to achieve the effect of cleaning the bristles 23.
