[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the breeding and cultivation device for forestry of the present invention is provided with a plurality of vertical rods 21 on the base 10, and a plurality of carrying boxes 22 are slidably provided on the vertical rods 21 in sequence, and a central outer cylinder 23 is provided on the carrying box 22, and a threaded hole 24 is provided on the central outer cylinder 23; a motor 25 is provided on the base 10, and the output shaft of the motor 25 is connected to a rotating shaft 26, and a central inner cylinder 27 is rotatably provided on the rotating shaft 26, and an external thread 28 corresponding to the threaded hole 24 is provided on the central inner cylinder 27, and a spline 29 is slidably provided on the rotating shaft 26, and a spline groove 30 corresponding to the spline 29 is provided on the central inner cylinder 27.

[0017] Plants are bred and cultivated through the carrier boxes 22. When the spacing between adjacent carrier boxes 22 needs to be adjusted, the corresponding splines 29 are first controlled to slide along the rotating shaft 26 into the spline grooves 30 on the central inner cylinder 27, so that the rotating shaft 26 and the central inner cylinder 27 can rotate synchronously. The output shaft of the motor 25 drives the rotating shaft 26 to rotate, and drives the central inner cylinder 27 to rotate, so that the central outer cylinder 23 and the carrier boxes 22 slide up and down along the vertical rod 21 to automatically adjust the spacing between adjacent carrier boxes 22 and adjust the reserved space for plant growth. There is no need for manual weight bearing, and the adjustment process is time-saving and labor-saving, which is convenient for single-person operation.

[0018] The carrier box 22 is provided with a partition 11. Multiple cultivation boxes 12 are located above the partition 11. A valve 13 is provided on the partition 11, and the valve 13 is equipped with a corresponding power supply and control module. The bottom of the carrier box 22 is provided with multiple spray holes 14. A tube 15 is provided on one side of the carrier box 22, communicating with the interior thereof, for introducing water or nutrient solution into the carrier box 22. The partition 11 divides the carrier box 22 into an upper irrigation chamber and a lower hydrophobic chamber. Water enters the irrigation chamber through the tube 15, immersing the bottom of the cultivation boxes 12 in water and irrigating the plants within the cultivation boxes 12. Nutrient solution is sprayed directly onto the plants in the topmost cultivation box 12. An appropriate amount of nutrient solution is introduced into the irrigation chamber through the tube 15. When the valve 13 is opened, the nutrient solution enters the hydrophobic chamber through the valve 13 and is sprayed onto the plants in the lower cultivation boxes 12 through the spray holes 14. The above structure and principle of irrigating plants and spraying nutrient solution are prior art and will not be described in detail here.

[0019] Preferably, the rotating shaft 26 includes a plurality of circular shafts 31 and square shafts 32 arranged at intervals, a square hole 33 corresponding to the square shaft 32 is opened on the spline 29, an electromagnet 34 is provided on the rotating shaft 26, and the spline 29 is made of a permanent magnet, so that the electromagnet 34 produces a repulsive effect on the spline 29 when energized, and a spring 35 is provided between the electromagnet 34 and the spline 29.

[0020] The control electromagnet 34 is energized to repel the spline 29 , and the spline 29 overcomes the elastic force of the spring 35 and slides along the square shaft 32 into the spline groove 30 . At this time, the rotating shaft 26 can rotate synchronously with the central inner cylinder 27 .

[0021] Among them, the lower end of the square shaft 32 extends into the central inner cylinder 27 for a certain distance, so that the spline 29 has sufficient length to cooperate with the spline groove 30, making the drive between the rotating shaft 26 and the central inner cylinder 27 more stable; the upper end of the square shaft 32 extends out of the central inner cylinder 27 for a certain distance, so that the spline 29 can be disengaged from the spline groove 30, thereby disconnecting the rotating shaft 26 from the central inner cylinder 27.

[0022] Among them, in actual use, when it is necessary to adjust the up and down movement of a certain carrier box 22, the corresponding electromagnet 34 is controlled to be energized, while the electromagnets 34 corresponding to other carrier boxes 22 that do not need to be adjusted are in the power-off state. Under the action of the spring 35, the spline 29 is disengaged from the spline groove 30, and the rotating shaft 26 is disconnected from the central inner cylinder 27, that is, the rotating shaft 26 rotates relative to the central inner cylinder 27, and the central inner cylinder 27 is stationary.

[0023] The spring 35 is a tension spring. Of course, those skilled in the art can select and configure the magnetic pole orientation of the electromagnet 34, the magnetic pole orientation of the spline 29 made of a permanent magnet, and whether the spring 35 is a compression spring or a tension spring, according to actual circumstances, to control the mating connection between the spline 29 and the spline slot 30. The electromagnet 34 and motor 25 are both equipped with corresponding power supplies, electrical wiring, control modules, and other structures. The control module of the electromagnet 34, such as a control button, can be installed on the current carrier box 22 to control the power on and off of the electromagnet 34.

[0024] Preferably, a rounded corner 36 is formed at one end of the spline 29 close to the spline groove 30 to facilitate the spline 29 to slide along the square shaft 32 into the spline groove 30 .

[0025] Preferably, the rotating shaft 26 is rotatably disposed on the inner side of the central inner cylinder 27 via a bearing 37 . A plurality of bearings 37 may be provided to enhance the driving stability of the rotating shaft 26 and the central inner cylinder 27 .

[0026] Preferably, a vertical hole 38 corresponding to the vertical rod 21 is formed on the carrying box 22 .

[0027] Preferably, a plurality of legs 39 are provided on the base 10 .

[0028] Of course, universal rollers can also be used to replace the legs 39 to facilitate the movement of the device.

[0029] The working principle of this utility model is as follows:

[0030] Plants are bred and cultivated using multiple cultivation boxes 12 on a carrier box 22. When the spacing between adjacent carrier boxes 22 needs to be adjusted, the electromagnet 34 corresponding to the current carrier box 22 is energized to repel the spline 29. The spline 29 slides along the square shaft 32 into the spline groove 30. The output shaft of the motor 25 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the central inner cylinder 27 to rotate synchronously, so that the central outer cylinder 23 drives the corresponding carrier box 22 to slide up and down along the vertical rod 21, automatically adjusting the spacing between adjacent carrier boxes 22 and adjusting the reserved space for plant growth. This process saves time and effort and is easy for one person to operate. After the adjustment is completed, the electromagnet 34 corresponding to the current carrier box 22 is de-energized. Correspondingly, under the action of the spring 35, the spline 29 disengages from the spline groove 30, and the rotating shaft 26 is disconnected from the central inner cylinder 27.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
