Abstract
Description
Technical Field
[0001] The utility model relates to a limiting component of an anti-fumigation cover for sulfur fumigation in a strawberry greenhouse. Background Art
[0002] Strawberries are rich in nutrients, delicious, and have high economic value. They are very popular and are being cultivated more and more. Strawberries are mostly cultivated in greenhouses. In greenhouse cultivation, powdery mildew is one of the common diseases of strawberries. For the prevention and control of powdery mildew of strawberries in greenhouses, sulfur fumigation is a common method, that is, using a sulfur fumigator to heat the sulfur placed in it, so that the sulfur is vaporized and diffused throughout the greenhouse, thereby preventing and controlling powdery mildew.
[0003] When using a sulfur fumigator for fumigation, in order to prevent the rising sulfur gas from impacting the film on the top of the greenhouse and reacting chemically with the film to harden and damage the film, a larger anti-fumigation cover is usually hung above the sulfur fumigator. When hanging, the anti-fumigation cover is installed on a rope hanging from the top of the greenhouse or a hook connected to the rope. For example, a hole is opened in the middle of the anti-fumigation cover, and the rope is fixed after passing through the hole, and the sulfur fumigator is hung at the lower end of the rope. For cost saving and convenient operation, the anti-fumigation cover is usually made of cardboard or made into an umbrella shape with a film. However, the process of making an umbrella shape with a film is relatively cumbersome, and whether it is cardboard or an umbrella-shaped film, when it is hung above the fumigator, it will tilt in most cases because the center of gravity is not easy to grasp, resulting in a smaller area for shielding sulfur gas, which affects the shielding effect. Therefore, it needs to be adjusted many times, and the operation is extremely cumbersome.
[0004] Patent document (CN2013203238737) discloses an automatic constant temperature sulfur fumigator, which has an umbrella-shaped anti-fumigation cover directly above the main body of the fumigator. However, the top of the anti-fumigation cover is lower than the top of the handle, that is, the anti-fumigation cover is located inside the handle. Although the sulfur fumigator can also prevent sulfur gas from impacting the top of the greenhouse and causing the greenhouse film to harden, the anti-fumigation cover is too low, and the rising sulfur gas is blocked by the anti-fumigation cover as soon as it leaves the evaporating aluminum pot, which greatly reduces the diffusion range of the sulfur gas, thereby affecting the disease prevention effect; and the umbrella-shaped anti-fumigation cover will cause the rising sulfur gas to descend along the inner surface of the umbrella, thereby greatly reducing the diffusion range of the sulfur gas, thereby affecting the disease prevention effect; and, each time the evaporating aluminum pot is taken out for cleaning or sulfur is contained, the anti-fumigation cover needs to be removed, which is inconvenient to operate. Utility Model Content
[0005] In order to solve the problem of tilting when the anti-fumigation cover is installed and the problem of affecting the diffusion range of sulfur gas, the utility model provides a limiting piece of an anti-fumigation cover for sulfur fumigation in a strawberry greenhouse.
[0006] The limiter of the anti-smoke cover for sulfur fumigation in the strawberry greenhouse described in the utility model comprises a threaded rod and two nuts used in conjunction with the threaded rod, the lower end of the threaded rod is connected with a hook body for hooking the handle of the sulfur fumigator, and the upper end is provided with a through hole for the hook or the rope to pass through for hanging. In this way, a simple anti-smoke cover can be made of cardboard, for example, a hole is opened in the middle of the cardboard, a nut is first screwed into the threaded rod, the cardboard is sleeved on the threaded rod through the hole, and then another nut is screwed in and tightened, so that the anti-smoke cover made of cardboard can be fixed horizontally. The hook body at the lower end of the threaded rod can hook the handle of the sulfur fumigator, and the through hole at the upper end can pass through a soft rope and tie a knot to form a hanging ring, which is hung on the hook on the rope hanging from the top of the greenhouse. The anti-smoke cover made of cardboard is horizontal and far away from the sulfur fumigator, so that the rising sulfur gas can meet the requirements of the diffusion range and will not impact the film on the top of the greenhouse. Since it is a threaded rod, the height of the anti-fumigation cover can be adjusted by changing the position of the nut fastening, so as to better meet the sulfur gas diffusion range and the anti-fumigation range.
[0007] In order to make the anti-smoking cover more stable and not tilted, two gaskets are also included, and a hole is opened in the center of the gasket for the threaded rod to pass through. In this way, the two gaskets are sleeved on the threaded rod and located between the two nuts to clamp the anti-smoking cover sleeved on the threaded rod, which can make the anti-smoking cover more stable and firm.
[0008] In order to make it easier to punch holes in cardboard, a simple anti-smoking cover is made, and the upper end of the threaded rod is a conical tip. In this way, just prepare the cardboard, and then use the tip of the threaded rod to pierce the cardboard and put it on the threaded rod. The hole at the piercing point matches the diameter of the threaded rod, so that the rising sulfur gas will not leak out through the hole, and the anti-smoking effect is better.
[0009] In order not to damage the threads on the threaded rod, the through hole is located on the conical surface of the conical tip. In this way, no matter whether the hook or the wire rope is passed through the through hole, the thread structure on the threaded rod will not be damaged, thereby extending the service life.
[0010] In order to further meet the requirements of sulfur gas diffusion range and make the anti-fumigation cover more stable and not tilted, the length of the threaded rod is 10-30cm; the gasket is square with a side length of 3-15cm.
[0011] Beneficial effects: The limiter of the utility model is suitable for a simple cardboard anti-smoke cover, which can keep the anti-smoke cover horizontal and not tilted, thereby blocking the sulfur gas from impacting the top film of the greenhouse to the greatest extent and playing a protective role. At the same time, it also makes the diffusion range of sulfur gas in the greenhouse meet the requirements, thereby achieving the prevention and control of powdery mildew, and also saves the previous process of frequently adjusting the anti-smoke cover to make it horizontal. The operation is simple, time-saving and labor-saving. In addition, the height of the anti-smoke cover can be adjusted by changing the fastening position of the nut to better meet the requirements of the sulfur gas diffusion range and the anti-smoke range; by arranging a gasket, the anti-smoke cover is more stable and not tilted; by setting the upper end of the threaded rod as a conical tip, it is convenient to punch holes in the cardboard to make a simple anti-smoke cover; by making the through hole located on the conical surface of the conical tip without damaging the threads on the threaded rod, the service life is extended; by setting the length of the threaded rod and the size of the gasket, the requirements of the sulfur gas diffusion range are further met, and the anti-smoke cover is further stabilized and not tilted.
