Description

Technical Field

[0001] The utility model belongs to the technical field of seedling raising tools, and in particular relates to a small greenhouse device. Background Art

[0002] If laboratory seedlings are directly transplanted into a natural environment, they often have difficulty surviving and fail to survive due to the large changes in the internal and external environment. Therefore, in order to improve the survival rate of laboratory seedlings, it is necessary to use seedling training and acclimatization methods before transplanting to improve the seedlings' ability to adapt to changes in temperature and humidity. The current common method is to plant the seedlings in the nutrient pots in an artificial climate chamber for acclimatization transition, and then transplant them to the field or outdoors after gradually adapting to the environment. During the seedling training and acclimatization process, in order to create a suitable living environment for the seedlings, a transparent film needs to be wrapped around the nutrient pots in the early stage of acclimatization to keep the seedlings warm and moisturized, thereby forming an artificial microclimate chamber.

[0003] As the seedlings grow, the space and nutrition can no longer meet the plant growth needs. If the nutrient pot is replaced, the above steps need to be repeated again. If the experiment needs to observe the root physiology and growth of the seedlings, the roots need to be pulled out to obtain data, which is very inconvenient. At present, the operation of wrapping the artificial microclimate chamber with plastic wrap is time-consuming and laborious, and requires the cooperation of multiple people. It cannot meet the needs of intuitively observing the root physiology and growth changes. It is very necessary to improve this process. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a small greenhouse device to solve the problems of failure of seedling training caused by environmental changes in the existing seedling domestication process and the need to wrap plastic wrap of different heights around the nutrient pots according to the growth height of the seedlings, which is cumbersome and inconvenient to operate.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] A small greenhouse device comprises a basin body, a support assembly is threadedly connected to the basin body, a thermal insulation film sleeve is sleeved on the support assembly, a ventilation plate is connected to the top end of the thermal insulation film sleeve, the ventilation plate is provided with ventilation holes and mounting holes, an elastic sleeve is provided at the bottom end of the thermal insulation film sleeve, and the elastic sleeve is sleeved on the basin body; the support assembly comprises a rod barrel, the bottom end of the rod barrel is detachably connected to the basin body, a screw is threadedly connected to the rod barrel, the screw is inserted into the mounting hole of the ventilation plate, and a boss for supporting the ventilation plate is provided at the top end of the screw.

[0007] On the basis of the above technical solution, the present invention also makes the following improvements:

[0008] Furthermore, a perforated plate is installed on the vent plate, a through hole corresponding to the vent hole is provided on the perforated plate, a limiting column is provided on the perforated plate, a limiting hole is provided on the vent plate, and the limiting column is inserted in the limiting hole, so as to facilitate the adjustment of the flow size between the vent hole and the outside.

[0011] Furthermore, a rubber cap is provided on the top of the screw rod, which plays a buffering role and improves the aesthetics, safety and comfort of use.

[0012] The beneficial effects of the utility model are as follows: by rotating the screw rod, the length of the screw rod extending out of the rod barrel can be changed, thereby adjusting the overall height of the support assembly, and then increasing the height of the thermal insulation film cover to adapt to seedling domestication operations at different heights.

[0023] The support assembly 2 includes a rod barrel 21, the bottom end of which is detachably connected to the pot body 1. A threaded hole may be provided on the pot body 1, and a thread may be provided on the bottom end of the rod barrel 21. The folded edge of the pot body 1 needs to be appropriately thickened. A sleeve may also be provided on the pot body. The bottom end of the rod barrel 21 is inserted into the sleeve. The inner thread of the rod barrel 21 is connected with a screw rod 22. The screw rod 22 is inserted into the mounting hole 42 of the air permeable plate 4. The top end of the screw rod 22 is provided with a boss 23 for supporting the air permeable plate 4. By rotating the screw rod 22, the length of the screw rod 22 extending out of the rod barrel 21 can be adjusted, so that the thermal insulation film cover 3 can be raised or lowered to accommodate seedlings of different heights.
