Description

Technical Field

[0001] The utility model belongs to the technical field of hail-proof nets, and particularly relates to a hail shaking device for a hail-proof net. Background Art

[0002] In agricultural production, to prevent disaster weather such as hail, hail-proof bombs are usually used. Especially in recent years, when setting up hail-proof nets in seedling cultivation applications, the attack of hail can be effectively prevented;

[0003] A hail-proof net is a net-shaped fabric made of polyethylene as the main raw material by adding chemical auxiliaries such as anti-aging and anti-ultraviolet agents, and is manufactured by wire drawing. It has the advantages of large tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and odorless, and easy disposal of waste. It can prevent natural disasters such as hail. It is convenient to collect and store during normal use, and the correct storage life can reach about 3 - 5 years;

[0004] Traditional hail-proof nets still have certain defects during use. Traditional hail-proof nets are made of materials such as hemp ropes, which have a certain elasticity. When there are many hails, they pile up together and cannot melt, and the hail-proof net needs to bear a large gravity, resulting in a short service life. Content of the Utility Model

[0005] To solve the problems raised in the above background art, the utility model provides a hail shaking device for a hail-proof net, which includes a hail-proof net support and a hail-proof net arranged on the top of the hail-proof net support. Pillars are fixedly arranged at the bottoms of the left and right ends of the hail-proof net support. A limiting sliding cavity is opened at the top of the pillar, and a limiting plate is fixed between the two pillars. A shaking component is fixedly arranged on the limiting plate.

[0006] As a hail shaking device for a hail-proof net of the utility model, preferably, a U-shaped push rod that slides up and down is arranged inside the two limiting sliding cavities.

[0007] As a hail shaking device for a hail-proof net of the utility model, preferably, the shaking component includes a power mechanism fixed on the limiting plate and a guiding mechanism fixed on the limiting plate.

[0008] As a hail shaking device for a hail-proof net of the utility model, preferably, the power mechanism includes a reduction motor fixed on one side wall of the limiting plate and a bearing seat fixed on the other side wall of the limiting plate.

[0009] As a hail shaking device for a hail-proof net of the utility model, preferably, a crank is movably arranged on the bearing seat, and the output end of the reduction motor is fixedly connected to the crank on the bearing seat and drives the crank to perform circular rotation.

[0010] As a hail shaking device for an anti-hail net of the present utility model, preferably, the guiding mechanism includes a slideway fixed on the limiting plate, a guide block is clamped on the slideway, and the top of the guide block is fixedly connected with a U-shaped push rod through a top rod.

[0011] As a hail shaking device for an anti-hail net of the present utility model, preferably, the crank and the guide block are movably connected through a connecting rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] When encountering hail in bad weather, start the reduction motor to drive the crank to rotate in a circle. The crank drives the guide block to move up and down reciprocally on the slideway through the connecting rod, and then drives the U-shaped push rod to move up and down through the top rod. At this time, the U-shaped push rod pushes the center of the anti-hail net to rise and fall, thereby shaking the hail on the anti-hail net and preventing the hail from accumulating and damaging the anti-hail net.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 As shown;

[0027] A hail shaking-off device for an anti-hail net comprises an anti-hail net support 1 and an anti-hail net 2 arranged on the top of the anti-hail net support 1.

[0028] In the present embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "traditional hail prevention nets still have certain defects when used. Traditional hail prevention nets are made of hemp rope and other materials, which have certain elasticity. When there are a lot of hail, they pile up together and cannot melt. The hail prevention nets need to withstand a large gravity, resulting in a shortened service life." In terms of actual use, this problem is obviously a real and difficult to solve problem. In view of this, in order to solve this technical problem, a hail shaking-off device for a hail prevention net is provided on this basis.

[0029] like Figures 1-5 As shown in the figure;

[0030] In combination with the above content, the anti-hail net bracket 1 is fixedly provided with pillars 11 at the bottom of the left and right ends, and a limiting sliding cavity 12 is opened on the top of the pillar 11. A limiting plate 13 is fixed between the two pillars 11, and a shaking component 3 is fixedly provided on the limiting plate 13.

[0031] In an optional embodiment, a U-shaped push rod 14 that slides up and down is disposed inside the two limiting sliding cavities 12 .

[0032] In an optional embodiment, the shaking assembly 3 includes a power mechanism 31 fixed on the limiting plate 13 and a guide mechanism 32 fixed on the limiting plate 13 .

[0033] In an optional embodiment, the power mechanism 31 includes a reduction motor 311 fixed to one side wall of the limit plate 13 and a bearing seat 312 fixed to the other side wall of the limit plate 13, and a crank 313 is movably provided on the bearing seat 312. The output end of the reduction motor 311 is fixedly connected to the crank 313 on the bearing seat 312, and drives the crank 313 to rotate in a circle.

[0034] In this embodiment: The reduction motor 311 drives the crank 313 to perform circular motion.

[0035] In an alternative embodiment, the guiding mechanism 32 includes a slideway 321 fixed to the limiting plate 13. A guide block 322 is clamped on the slideway 321. The top of the guide block 322 is fixedly connected to the U-shaped push rod 14 through a top rod 323. The crank 313 and the guide block 322 are movably connected through a connecting rod 33.

[0036] In this embodiment: The guide block 322 performs reciprocating up and down motion on the slideway 321, and then drives the U-shaped push rod 14 to perform up and down motion through the top rod 323.

[0037] Working principle of the present utility model:

[0038] When encountering hail in bad weather, start the reduction motor 311 to drive the crank 313 to perform circular motion. The crank 313 drives the guide block 322 to perform reciprocating up and down motion on the slideway 321 through the connecting rod 33, and then drives the U-shaped push rod 14 to perform up and down motion through the top rod 323. At this time, the U-shaped push rod 14 pushes the center of the hail protection net 2 to perform lifting and lowering operations, thereby shaking off the hail on the hail protection net 2 and preventing the hail from accumulating and damaging the hail protection net.

[0039] Finally, it should be noted that: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
