[0077] The first ends of the three inner support arms 61 are respectively hinged to the first sides of the three wheel plates 63, and the second ends of the three inner support arms 61 are respectively hinged to the inner end cover 59.

The nut sleeve 67 is fixedly sleeved on the rotating shaft 58, and the outer end cover 60 is connected to the outer end of the rotating shaft 58 through the second telescopic rod 66. That is, by setting the second telescopic rod 66, it can not only play a limiting role, but also be able to expand and contract with the change in diameter of the variable-diameter rear wheel 57.

[0078] Among them, each rotating shaft 58 is respectively installed with a bearing, and a bearing seat corresponding to each bearing is installed on the base box 9, and each bearing is correspondingly installed on each bearing seat. Among them, the rotating shafts 58 of the two variable diameter front wheels 56 can be connected to each other, and the rotating shafts 58 of the two variable diameter rear wheels 57 can be connected to each other.

The second variable diameter wheel driving mechanism includes a first gear 69, a second gear 70, a third gear 71, a collar gear 72, a screw sleeve 73, a rotary drive motor 74 and a linear drive motor (not shown in the figure), the screw sleeve 73 can be rotatably mounted on the rotating shaft 58, the inner end cover 59 is provided with a threaded hole, and the inner end cover 59 is threadedly connected to the outer peripheral surface of the screw sleeve 73 through the threaded hole. The first gear 69 is fixedly mounted on the rotating shaft 58, and the second gear 70 is fixedly mounted on the screw sleeve 73, and the first gear 69 and the second gear 70 are set in a gap. The inner ring of the collar gear 72 is provided with a sliding tooth groove, and the sliding tooth groove can slide with the first gear 69 and the second gear 70 respectively. That is, the collar gear 72 can move left and right along the first gear 69, but the collar gear 72 cannot rotate relative to the first gear 69. The collar gear 72 can move left and right along the second gear 70, but the collar gear 72 cannot rotate relative to the second gear 70. Moreover, the collar gear 72 can move from the first gear 69 to the second gear 70, and can also move from the second gear 70 to the first gear 69.

[0080] The third gear 71 is meshedly connected with the collar gear 72, and a limit plate for limiting the position of the third gear 71 is respectively provided at the left and right ends of the collar gear 72, and the third gear 71 is arranged between the two limit plates.

[0081] The output shaft of the rotary drive motor 74 is fixedly connected to the third gear 71, and the rotary drive motor 74 is fixedly mounted on the driving block of the linear drive motor through a support 75. That is, the linear drive motor can drive the rotary drive motor 74 to move left and right, and then drive the collar gear 72 to move left and right through the third gear 71, thereby realizing the position conversion of the collar gear 72 on the first gear 69 or the second gear 70.

[0082] When the diameter change is not required, the collar gear 72 is on the first gear 69. At this time, the third gear 71 is driven to rotate by the rotating drive motor 74, the third gear 71 drives the collar gear 72 to rotate, the collar gear 72 drives the first gear 69 to rotate, and the first gear 69 drives the rotating shaft 58 to rotate synchronously, so that each diameter-changing front wheel 56 and each diameter-changing rear wheel 57 rotate synchronously. At this time, the diameter-changing wheel group has the same function as the auxiliary wheel group, and the overall movement of the multifunctional planting box can be realized.

[0083] When the diameter needs to be changed, the linear drive motor drives the rotary drive motor 74 to move, thereby driving the collar gear 72 from the first gear 69 to the second gear 70 through the third gear 71, and then starting the rotary drive motor 74, driving the collar gear 72 to rotate through the third gear 71, the collar gear 72 drives the second gear 70 to rotate, and the second gear 70 drives the lead screw sleeve 73 to rotate. In this process, the inner end cover 59 can move left and right relative to the lead screw sleeve 73, thereby realizing the diameter changing function of the diameter changing wheel set. When the inner end cover 59 approaches the nut sleeve 67, under the action of the three inner support arms 61, the distance between each wheel piece 64 can be increased, thereby increasing the diameter of each diameter changing front wheel 56 and each diameter changing rear wheel 57, and at this time, the distance between the outer end cover 60 and the nut sleeve 67 is reduced accordingly. When the inner end cover 59 is away from the nut sleeve 67, under the action of the three inner support arms 61, the distance between the wheel plates 64 can be reduced, so that the diameter of each variable diameter front wheel 56 and each variable diameter rear wheel 57 is reduced. At this time, the distance between the outer end cover 60 and the nut sleeve 67 increases accordingly.

[0084] In some embodiments of the present invention, the multifunctional planting box further comprises an outer shell 76, which is a cylindrical shell with openings at both ends. The inner side walls of the outer shell 76 are respectively connected to the mounting plate 8 and the base box 9, so that the main box 1, the mounting plate 8, the lifting platform 7 and the base box 9 can be respectively arranged inside the outer shell 76, thereby playing a role in shielding and protecting the internal structure. Among them, an opening for the waste liquid collection box 36 to pass through is provided on the outer shell 76, which is convenient for cleaning the waste liquid in the waste liquid collection box 36. Among them, the diameter of the lifting platform 7 is smaller than the diameter of the mounting plate 8, and the outer diameter of the main box 1 is smaller than the diameter of the lifting platform 7. When the multifunctional planting box is lifted up and down, the lifting platform 7 can move up and down in the outer shell 76, thereby driving the main box 1 to extend or retract in the outer shell 76.

[0085] In some embodiments of the present invention, the multifunctional planting box further includes a controller (not shown) and an operation screen (not shown) disposed on the main box body 1, the operation screen being electrically connected to the controller, and the controller being electrically connected to each electrical device in the protective device, the irrigation device, the ventilation and heat-insulating device, the lifting and adjusting device, and the mobile obstacle-crossing device, respectively, so as to be able to control the working states of the protective device, the irrigation device, the ventilation and heat-insulating device, the lifting and adjusting device, and the mobile obstacle-crossing device, respectively. When in use, the operation control of the multifunctional planting box can be realized through the operation screen. The controller can also be wirelessly connected to a remote terminal, so as to realize remote control operation of the multifunctional planting box.

[0086] The working principle of the multifunctional planting box of the embodiment of the present invention is as follows:

[0087] When sensing a severe environment such as a storm, the controller of the multifunctional planting box receives a command and controls the protective cover of the protective device to unfold, forming a closed protective space above the main box 1, thereby protecting the crops planted in the main box 1 from damage by the external environment. When the planting area needs normal ventilation, the protective cover of the protective device can be controlled to retract.

[0088] When the protective cover is retracted but still cannot meet the ventilation requirements of the planting area, the hair dryer 6 is controlled to blow normal temperature air, thereby delivering normal temperature air to the main box 1 through the air supply pipeline. When the planting area needs to be kept warm, the hair dryer 6 is controlled to blow warm air, thereby delivering warm air to the main box 1 through the air supply pipeline to heat and keep the planting area warm.

[0089] According to the needs of plant growth, the water storage tank 2, the medicine storage tank 3 and the fertilizer storage tank 4 are controlled to release water, liquid medicine and liquid fertilizer respectively, and then the crops planted in the main box 1 are sprayed and irrigated through the delivery pipe group and the nozzle 5.

[0090] After finding a suitable environment, the multifunctional planting box is controlled to move through a mobile obstacle crossing device. During the movement, the planting box may encounter obstacles such as steps. At this time, it is necessary to control the variable diameter wheel group to change its diameter through a variable diameter wheel driving mechanism, so as to cross obstacles such as steps to ensure that the multifunctional planting box can be smoothly moved to the designated position, so that the crops planted in the main box 1 can better utilize sunlight.

[0091] When a suitable environment is reached, in order to adjust the height of the planting area so that the plants can better utilize sunlight and ensure the lighting needs of plant growth, the lifting and adjusting device can be controlled to drive the main box 1 to perform lifting and adjustment.

[0092] 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 replace some or all of the technical features therein with equivalents.
