DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] The utility model provides technical scheme: as Figures 1-3 As shown in the drawing, a kind of walnut seedling cold-proof device, including cover body 1, for covering walnut seedling, the bottom of cover body 1 is equipped with reinforcing rib 11, the top of cover body 1 is equipped with through slot 12, cover body 1 is equipped with multiple circulation ports 13 on circumference, shell 2 is equipped on cover body 1, the upper end of shell 2 is symmetrically equipped with two handles 23, the bottom of shell 2 is clamped with base 21, and base 21 is fixedly connected with the outer wall of cover body 1. When using, cover body 1 is directly equipped above walnut seedling, the bottom of cover body 1 is in contact with cultivation ground, the stability when placing cover body 1 can be improved by the reinforcing rib 11 of widened arrangement, again by handle 23 moves shell 2, the bottom of shell 2 is moved into the recess of base 21, to fix shell 2 in this way.

[0024] In addition, the top of shell 2 is provided with movable seat 24, power supply seat 3 is installed on movable seat 24, movable seat 24 is threadedly connected with the top of shell 2, movable seat 24 is clamped with power supply seat 3, and anti-skid line is provided on the side wall of power supply seat 3, it needs to be explained that power supply seat 3 is electrically connected with external power supply equipment, provides the energy required for heat preservation lamp 31 work, further, since power supply seat 3 is clamped between movable seat 24, power supply seat 3 can drive movable seat 24 synchronous rotation by screwing, movable seat 24 is separated from shell 2 by the thread setting, can maintain or replace heat preservation lamp 31.

[0025] As Figure 4 And Figure 5As shown, the lower part of the power seat 3 is electrically connected with the heat preservation lamp 31, the lower part of the heat preservation lamp 31 is provided with the lens 4, and the lens 4 is a concave lens. The lens 4 is arranged in the through groove 12, and the diameter R1 of the lens 4 is equal to the diameter R2 of the through groove 12, that is, R1=R2. A plurality of support rods 41 are circumferentially arranged on the side wall of the lens 4, and the ends of the plurality of support rods 41 away from the lens 4 are fixedly connected to the inner wall of the shell 2.

[0026] Specifically, the lens 4 is installed below the heat preservation lamp 31 through the fixation of the plurality of support rods 41. Since the lens 4 is arranged as a concave lens, when the heat preservation lamp 31 is working, the light emitted by the heat preservation lamp 31 can be diffused, so that the light irradiating the walnut seedlings below is relatively soft. The light is uniformly distributed in the cover body 1, avoiding the growth inhibition of the seedlings due to the excessive transport of auxin in the seedlings caused by the oblique irradiation of light, ensuring the balanced growth of each part of the walnut seedlings, and improving the cultivation quality of the walnut seedlings.

[0027] In order to achieve better cold prevention effect, the following improvements are made, such as Figure 3 With Figure 4 As shown, a plurality of air inlets 22 are circumferentially arranged on the shell 2, and a blocking mechanism 5 is arranged between the air inlets 22 and the circulating port 13. The blocking mechanism 5 includes a plurality of first extension plates 51 and second extension plates 52. The plurality of first extension plates 51 and second extension plates 52 are both circular rings, and arc-shaped grooves are arranged on the plurality of first extension plates 51 and second extension plates 52 respectively. The plurality of first extension plates 51 are fixedly connected to the outer wall of the cover body 1, and the plurality of second extension plates 52 are fixedly connected to the inner wall of the shell 2. The plurality of first extension plates 51 and second extension plates 52 are arranged in a staggered manner.

[0028] Specifically, the inner wall of the shell 2 and the outer wall of the cover body 1 form a circulating chamber. The external air enters the shell 2 through the air inlets 22. With the heating of the heat preservation lamp 31, the hot air in the cover body 1 rises and is guided by the arc surface of the circulating port 13 and the lens 4 to diffuse into the shell 2 and mix with the incoming external air, avoiding the direct blowing of cold wind to the walnut seedlings, providing sufficient oxygen for the seedlings, promoting their respiration and metabolism, and also helping to discharge harmful gases and excessive water vapor in the cover body 1. At the same time, the first extension plates 51 and the second extension plates 52 are guided by the arc surfaces at the bottom to form local vortex flow, and the staggered arrangement provides mutual shielding, which can effectively block the pests mixed in the external air. Further, sugar vinegar liquid or other trapping agents can be added to the arc-shaped grooves on the first extension plates 51 and the second extension plates 52 to improve the control effect on pests, avoid the damage of pests to the growth of walnut seedlings, and improve the cultivation quality of walnut seedlings.

[0029] The various embodiments in the specification are described in a related manner, and the same and similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0030] The above only describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application is included in the protection scope of the present application.
