Description

Technical Field

[0001] This utility model relates to the field of cultivation devices, and more specifically, to a sealed cultivation cover for lettuce that prevents diseases and pests. Background Technology

[0002] In home lettuce cultivation, pests and diseases have always been significant factors affecting crop growth and yield. Open cultivation methods are insufficient to effectively resist the invasion of external pests and diseases, making lettuce susceptible to damage and impacting both yield and quality. To address this issue, agricultural technicians began exploring sealed cultivation techniques. While early sealed cultivation covers could isolate pests and diseases to some extent, they often suffered from insufficient sealing and poor ventilation, hindering the normal growth of lettuce.

[0003] In a closed growing environment, lettuce is susceptible to pests and diseases during its growth cycle due to the poor sealing performance of the cover. Furthermore, disassembling the cover and opening it to remove the lettuce is quite cumbersome and inconvenient.

[0004] Therefore, we have made improvements and proposed a sealed cultivation cover for lettuce to prevent diseases and pests. Utility Model Content

[0005] The purpose of this invention is to address the problem that lettuce is susceptible to pests and diseases during its growth cycle due to the poor sealing performance of the sealing cover.

[0006] In order to achieve the above-mentioned objectives, this utility model provides a sealed cultivation cover for lettuce that prevents diseases and pests, thereby improving the above-mentioned problems.

[0007] The application is as follows:

[0008] It includes a base box and a flip cover that flips to both sides on the side of the base box, and the flip cover has two symmetrical semi-circular holes;

[0009] The bottom box is elastically provided with a mounting frame that is coplanar with the opening and closing seam of the flip cover. Two blocks are rotatably connected to the mounting frame along the axis. The blocks are circular open platforms with a top and bottom circle. The semi-circular hole is located on the outside of the flip cover and is fixedly connected to a semi-circular protrusion. The projection of the blocks covers the semi-circular protrusion when the flip cover is closed.

[0010] When the square face of the block first contacts the semi-circular protrusion, the two flip covers are squeezed together.

[0011] Preferably, the square surface area of ​​the block is smaller than the circular surface area, and the square surface of the block has a plurality of filter holes.

[0012] Preferably, the outer ring diameter of the semi-circular protrusion is smaller than the inner ring diameter of the circular surface of the block. When the semi-circular protrusion and the circular surface of the block are on the same plane, the circular surface of the block is fitted over the outer side of the semi-circular protrusion.

[0013] Preferably, two semi-circular filter plates are symmetrically arranged on the inner wall of the base box, a fan-shaped plate coplanar with the semi-circular filter plates is fixedly connected to the inner wall of the flip cover, a water pipe is fixedly connected to the center of the outer wall of the base box, and both ends of the mounting frame are fixedly connected to the water pipe.

[0014] Preferably, the two flaps and the bottom box form a capsule-shaped container, the surface area of ​​the flaps is half that of the bottom box, and a planting plate is fixedly connected between the two semi-circular filter plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. In order to solve the problem of poor sealing of cultivation covers in the prior art, this application sets up a block that flips on the mounting frame. This block, through its own structure, not only prevents small pests from passing through, but also ensures air circulation. Furthermore, during the rotation of the block, the sloping block after the flipping can squeeze the cover, making the cover easier to open. This achieves the functions of sealing and insect prevention, while also providing the additional benefit of easy opening and closing. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] As described in the background art, due to the poor sealing performance of the sealing cover, lettuce is susceptible to pests and diseases during its growth cycle.

[0026] To solve this technical problem, this utility model provides a sealed cultivation cover for lettuce that prevents diseases and pests. It uses a protective plate to form a locking structure to ensure the closure of the cultivation cover and maintain good sealing performance.

[0027] For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The specific components of a sealed lettuce cultivation cover for disease and pest prevention include:

[0028] The bottom box 1 and the flip cover 4 which is set on the side of the bottom box 1 and flips to both sides. The flip cover 4 has two symmetrical semi-circular holes. By reserving the semi-circular holes, a channel is provided for the entire cultivation cover to communicate with the outside. The lettuce in the cultivation cover can exchange air with the outside, so that the gas flow can be guaranteed and the gas elements in the growth environment of the lettuce can be replenished.

[0029] The base box 1 is elastically provided with a mounting frame 2 that is coplanar with the opening and closing seam of the flip cover 4. Two blocks 3 are rotatably connected to the mounting frame 2 along the axis. The blocks 3 are circular open platforms with a round top and a round bottom. A semi-circular hole is located on the outer arc of the flip cover 4 and a semi-circular protrusion 5 is fixedly connected. When the flip cover 4 is closed, the projection of the blocks 3 covers the semi-circular protrusion 5. By using the circular open surface of the blocks 3 in conjunction with the mounting frame 2 that is elastically fixed to the water pipe 8, the blocks 3 can move up and down above the semi-circular protrusion 5 and can control whether the blocks 3 contact the semi-circular protrusion 5. Thus, the blocks 3 are fitted onto the outer ring formed by the two semi-circular protrusions 5 and restrict the flip cover 4 from flipping to the sides, ensuring the overall airtightness of the device. At the same time, the blocks 3 of the platform can ensure that pests and diseases cannot enter the filter hole 31 end, thus achieving the effect of preventing pests and diseases.

[0030] When the square face of block 3 first contacts the semi-circular protrusion 5, the two flip covers 4 are squeezed. At the same time, when block 3 flips over and the narrow square face faces the semi-circular protrusion 5, the elastically set mounting frame 2 has a downward pressing tendency. Block 3 can squeeze the flip covers 4 to move to both sides, so that the flip covers 4 can be opened better, making the process of users taking out raw vegetables smoother.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The sealed cultivation cover for lettuce is designed to prevent pests and diseases. The square surface area of ​​block 3 is smaller than that of the circular surface. Several filter holes 31 are provided on the square surface of block 3. The filter holes 31 restrict pests and diseases of certain sizes from entering the interior of the cultivation cover, thus preventing them from damaging the lettuce and causing economic losses.

[0035] The outer ring diameter of the semi-ring protrusion 5 is smaller than the inner ring diameter of the circular surface of the block 3. When the semi-ring protrusion 5 and the circular surface of the block 3 are on the same plane, the circular surface of the block 3 is fitted over the outside of the semi-ring protrusion 5. When the circular surface of the block 3 is fitted over the outside of the semi-ring protrusion 5, since the semi-ring protrusion 5 is fixed to the flip cover 4, the flip cover 4 cannot be flipped to the sides, thus ensuring the airtightness of the top of the cultivation cover.

[0036] Two semi-circular filter plates 7 are symmetrically arranged on the inner wall of the bottom box 1. A fan-shaped plate 6 coplanar with the semi-circular filter plates 7 is fixedly connected to the inner wall of the flip cover 4. A water pipe 8 is fixedly connected to the center of the outer wall of the bottom box 1. Both ends of the mounting frame 2 are fixedly connected to the water pipe 8. The maximum water level can be controlled by the semi-circular filter plates 7 and the fan-shaped plate 6, so that the water will not submerge the lettuce in a short time. At the same time, the semi-circular filter plates 7 can filter out insect eggs and aquatic insects in the water, further enhancing the pest and disease prevention properties of the cultivation cover.

[0037] Two flip covers 4 and a bottom box 1 form a capsule-shaped container. The surface area of ​​the flip covers 4 is half that of the bottom box 1. A planting plate 9 is fixedly connected between the two semi-circular filter plates 7. It should be noted that the flip covers 4 are made of transparent material to ensure sunlight input.
