Description

Technical Field

[0001] The utility model relates to the technical field of forest seedling protection devices, in particular to an antifreeze device for cultivating forest seedlings. Background Art

[0002] During the tree planting process, the seedlings in the seedling stage have relatively weak resistance to cold weather and are easily affected by the weather, causing frostbite, which affects their growth in the following year. For this reason, the seedlings are usually treated with cold protection in advance by wrapping straw ropes, straw, and film around the trunks of the seedlings to resist the severe cold. However, the construction speed is slow, and when there are many seedlings, a lot of manpower and time are required, and the overall cold protection effect is poor, and it is unable to cope with extremely cold weather. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an antifreeze device for cultivating forest seedlings in response to the above-mentioned technical deficiencies. The device can quickly wrap the trunk part, has a fast construction speed, and is simple and convenient to operate. At the same time, the top of the sheath is sealed to improve the sealing and heat preservation effect to meet the use in cold weather.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model includes:

[0005] The sheath is used in pairs and connected by bolts to form a protective space for the trunk of the forest seedling. A heat-insulating layer is provided inside the sheath. A positioning plate is provided below the sheath. A rectangular notch is provided on the top of the sheath, and a closing component in contact with the trunk is provided in the rectangular notch.

[0006] Preferably, the thermal insulation layer is made of foam plastic material.

[0007] Preferably, sliding holes are provided on the sleeve on both sides of the rectangular slot; the closing assembly includes a threaded rod, a cross plate and a surface layer; the threaded rod and the sleeve are threadedly connected; guide rods connected to the sliding holes are provided at both ends of the cross plate, and a flexible part is provided at the end of the guide rod, and the middle part of the cross plate is connected to the threaded rod by a rotating shaft; the surface layer is respectively connected to the rectangular slot and the flexible part.

[0008] Preferably, the flexible member is in the shape of a rectangular sheet and is made of spring steel.

[0009] Preferably, a guide groove is provided in the sliding hole; and a plurality of sliding blocks connected to the guide groove are respectively provided on both sides of the surface layer.

[0010] Preferably, the surface layer comprises a fabric layer and a film layer arranged above the fabric layer.

[0011] Preferably, a reinforcement strip is provided on the front end surface of the surface layer.

[0012] Preferably, a reinforcement rod is provided on the positioning plate.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The overall installation operation can be completed by splicing two sheaths, fixing them with bolts, and inserting them into the soil. Compared with traditional bundling operations, the construction time is short and the installation efficiency is high, which can meet the protection operation of a large range of forest seedlings;

[0015] 2. After the sheath is installed, by pushing the closing component to contact the tree trunk, the rectangular notch on the top can be closed to improve the cold-proof effect, maintain the stability of the internal temperature, and ensure the normal growth of the forest seedlings. At the same time, the structural design of the closing component can adapt to tree trunks of different diameters and has strong applicability;

[0016] 3. By adding an insulation layer inside the sheath, the temperature loss in the protected space can be effectively reduced to ensure temperature stability. At the same time, after the sheath is installed, it avoids cold wind blowing directly on the tree trunk, reduces humidity evaporation, and effectively improves the growth environment of the forest seedlings.
