Technical Field

[0001] The utility model relates to the technical field of insect-proof devices, in particular to an insect-proof device used for vegetable cultivation and planting. Background Art

[0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide a variety of nutrients such as vitamins and minerals necessary for the human body. In the process of vegetable cultivation, in order to improve the yield and quality of vegetables, it is necessary to provide them with a good growth environment. Among them, pest control is a relatively important link, and this link is closely related to the application of insect control devices.

[0003] Insect-proof devices generally isolate insects through insect-proof nets, which are usually constructed of mesh, cable ties and multiple arch supports.

[0004] In the existing insect-proof net construction process, the cut insect-proof net is laid on a bracket and then fixed to the bracket with ropes, cable ties, etc. to ensure that the insect-proof net is flat and not easily blown by the wind. During the process of frequent inspection or picking of vegetables, the insect-proof net usually needs to be opened frequently. After the insect-proof net is set up, the cable ties or ropes need to be untied when opening the insect-proof net, and the ropes need to be tied to the bracket again when closing the insect-proof net. This process is not convenient for quickly opening or closing the insect-proof net, and is inconvenient to use.

[0005] In addition, the use of insect-proof nets may cause the air permeability inside the insect-proof nets to deteriorate, which in turn leads to higher humidity inside the insect-proof nets, thus affecting the growth environment of vegetables, so it needs to be improved. Utility Model Content

[0008] The outer walls of the two driving columns at the rear end are fixedly connected to a support plate, the upper end of the support plate passes through and is connected to a threaded column by a thread, and the outer walls of the two driving columns at the front end are fixedly connected to a fixing plate, and the threaded column passes through a through hole opened in the upper end of the fixing plate and extends to the lower end of the fixing plate;

[0009] A fan is installed at the right end inside the frame, and the outer wall of the fan is connected to a delivery pipe. The other end of the delivery pipe passes through the upper end surface of one of the second brackets and extends to the interior of the second bracket and is connected to a cavity. A plurality of evenly distributed ventilation holes are opened on the front and back sides of the cavity.

[0010] In order to provide auxiliary support for the insect-proof net, as an insect-proof device preferably used for vegetable cultivation and planting, the outer wall of the rotating shaft is rotatably connected with a connecting rod, the left and right ends of the insect-proof net are fixedly connected to the limiting shaft, and the other end of the connecting rod is fixedly connected to the limiting shaft.

[0011] In order to increase the light transmittance of the insect-proof net, as an insect-proof device used for vegetable cultivation and planting of the present invention, the insect-proof net is preferably made of glass fiber fabric.

[0012] In order to play a role in repelling pests on the outer wall of the insect-proof net, as a preferred insect-proof device used for vegetable cultivation and planting of the utility model, an insect repellent is filled in the cavity.

[0013] In order to increase the sealing between the two second brackets, as a preferred insect-proof device applied to vegetable cultivation and planting of the present invention, rubber pads are provided on opposite sides of the two second brackets.

[0014] In order to increase the stability of the frame, as a preferred insect-proof device for vegetable cultivation and planting of the present invention, the lower end of the frame is fixedly connected with a plurality of evenly distributed limiting columns.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] When the insect-proof net needs to be opened, the threaded column is rotated to move the threaded column upward and away from the fixed plate connected thereto, and then the driving column at the front end and the driving column at the rear end are toggled to rotate in opposite directions around the rotating shaft, so that the insect-proof net is folded to the front and rear sides of the frame, respectively, so that the vegetables are exposed in the middle of the frame, which is convenient for workers to check or pick vegetables and is easy to use.

[0017] When the insect screen needs to be closed, the front driving column and the rear driving column are rotated in opposite directions around the rotating shaft to make the two second brackets abut each other, and then the threaded column is rotated and inserted into the fixing plate below to fix the front driving column and the rear driving column;
