[0007] Furthermore, the aperture of the insect-proof net is 40-60 meshes.

[0008] Furthermore, a tightening rope is provided at one end of the extension net.

[0009] Furthermore, a rotating shaft is rotatably inserted at the top of the inner cover, the outer cover is fixedly sleeved on the outer wall of the rotating shaft, and a rotating knob is fixedly connected to the top of the rotating shaft.

[0010] Furthermore, an anti-slip groove is provided on the outer wall of the rotating knob.

[0011] Furthermore, two barbs are fixedly connected to the outer wall of the ground-inserting cone.

[0012] The beneficial effects of the utility model are:

[0013] 1. Through the setting of the open ring, the extension net and the tightening ring, the hand is extended into the insect-proof cover through the open ring and the tightening ring, so as to weed and spot check the tobacco seedlings, thereby avoiding the opening of the insect-proof cover, thereby preventing pests from entering the insect-proof cover.

[0014] 2. The insect-proof cover is installed in the ground by inserting the ground cone into the soil, and the insect-proof cover is covered on the outside of the tobacco seedlings, so as to protect the tobacco seedlings and avoid affecting the planting of the tobacco seedlings.

[0015] 3. The rotating shaft is driven to rotate by turning the rotating knob, thereby driving the outer cover to rotate, so that the outer cover and the insect-proof net overlap, thereby keeping the tobacco seedlings warm to facilitate their growth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3The top of the fixing ring 1 is provided with an inner cover 2, and both sides of the inner cover 2 are clamped with insect-proof nets 3. The design of the insect-proof net 3 plays an insect-proof role to avoid affecting the planting of tobacco seedlings. An open ring 4 is clamped on the insect-proof net 3, and an extension net 5 is arranged on one side of the open ring 4. A tightening ring 6 is clamped on the other end of the extension net 5. The hand is extended into the insect-proof cover through the open ring 4 and the tightening ring 6, so as to weed and inspect the tobacco seedlings. A slide groove 8 is provided on the top of the fixing ring 1, and an outer cover 9 is slidably connected in the slide groove 8. The outer cover 9 is arranged on the outer side of the inner cover 2, and perforations 10 are arranged on both sides of the outer cover 9. A plurality of ground-inserting cones 14 are welded on the bottom of the fixing ring 1. The ground-inserting cones 14 are inserted into the soil, so that the insect-proof cover is installed in the ground, and the insect-proof cover is covered on the outside of the tobacco seedlings, so as to protect the tobacco seedlings.

[0022] The aperture of the insect-proof net 3 is 40-60 meshes, and a tightening rope 7 is provided at one end of the extension net 5. The tightening rope 7 is used to tighten one end of the extension net 5 to prevent insects from entering the insect-proof cover. A rotating shaft 11 is rotatably inserted at the top of the inner cover 2, and the outer cover 9 is fixedly sleeved on the outer wall of the rotating shaft 11. A rotating knob 12 is welded on the top of the rotating shaft 11. Turning the rotating knob 12 drives the rotating shaft 11 to rotate, thereby driving the outer cover 9 to rotate, so that the outer cover 9 overlaps with the insect-proof net 3, thereby keeping the tobacco seedlings warm. The outer wall of the rotating knob 12 is provided with an anti-slip groove 13, so as to facilitate the operation of the rotating knob 12. Two barbs 15 are welded on the outer wall of the ground cone 14, and the barbs 15 on the ground cone 14 prevent the ground cone 14 from being lifted out of the ground.

[0023] The working principle of this embodiment is as follows: when in use, first, insert the ground cone 14 into the soil, thereby installing the insect-proof cover in the ground, and make the insect-proof cover cover the outside of the tobacco seedlings. When the tobacco seedlings need to be kept warm, turn the rotating knob 12 to drive the rotating shaft 11 to rotate, thereby driving the outer cover 9 to rotate, and then make the outer cover 9 overlap with the insect-proof net 3, so as to keep the tobacco seedlings warm. When the temperature is high, turn the rotating knob 12 in the opposite direction to turn the outer cover 9 away from one side of the insect-proof net 3, so as to facilitate the cooling of the tobacco. When the tobacco seedlings need to be weeded or inspected, loosen the tightening rope 7, and extend the hand into the insect-proof cover through the open ring 4, so as to weed and inspect the tobacco seedlings.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
