Description
Technical Field
The invention relates to a device for agriculture and forestry production, in particular to an isolating device applied to plant protection.
Background
In agricultural production, pests are directly related to product quality and yield, and if pest control is not considered, yield is reduced if the pest control is not considered, and the pest control is not accepted if the pest control is considered. There are many existing methods for controlling pests, and they can be roughly classified into physical control and chemical control. In seasons with proper temperature, because the breeding speed of pests is very fast, one generation can be bred in dozens of days. Therefore, chemical agents are mostly used for prevention and treatment at present, and compared with physical prevention and treatment, chemical prevention and treatment have more instant effect. However, chemical control also has its deadly drawbacks, such as drug resistance, e.g. pesticide residues, e.g. pollution of the environment by penetration of pesticides into groundwater, are non-negligible and increasingly not accepted by the public. Moreover, in general chemical control, a good control effect can be achieved only by spraying for many times and regularly, which requires a large amount of manpower and material resources. Compared with chemical prevention and control, the insect prevention net is used for physical isolation to achieve the purpose of preventing and controlling pests, and has the advantages of being capable of achieving once and for all, once investment and many years of use. Although the isolation effect can only be effective for specific insect pests, and the effect cannot completely eradicate the insect pests compared with chemical control, the isolation method has the advantages of environmental protection and no damage to ecology, and is incomparable with the chemical control. Therefore, physical isolation remains the first choice for pest control in the production of green agricultural products and organic agricultural products. Physical isolation is currently most commonly done with insect nets.
The net for preventing and killing pests is made up of polyethylene as main raw material, ageing-resistant and ultraviolet-resistant chemical assistants and through drawing, and features high tension strength, high resistance to heat, water, corrosion and ageing, no poison and odour, and easy treatment of waste. Can prevent common pests such as piercing-sucking pests such as flies, mosquitoes, aphids, whiteflies, bemisia tabaci and the like, and can effectively prevent and control the invasion of imagoes such as cotton bollworms, asparagus caterpillars, prodenia lituras, scarab beetles and the like. Meanwhile, the existing insect-proof net also has the functions of shading sun and cooling, so that excessive transpiration of farmland moisture can be prevented in fact. In addition, the insect-proof net also has a certain wind-proof function, so that the insect-proof net has a certain protection function on the attack of wind and rain of crops. However, in the current insect-proof net construction, the main construction means generally includes: 1) the cover of the insect-proof net can be selected from the cover of a greenhouse, the insect-proof net is directly covered on a greenhouse frame, and the periphery of the insect-proof net is compacted by soil or bricks. The front door is left to open the cover, so that the door can be conveniently put in and taken out; 2) and covering a field of 2000-3500 square meters by using a horizontal shed frame, wherein the field is completely covered by using an insect-proof net. The form saves the gauze and the net rack, and the operation is convenient; 3) covering with small arched shed, bending bamboo sheet or steel bar into arched shed, inserting in the land, covering with insect-proof net on the arch frame, watering, directly watering on the net, and totally-enclosed covering without removing the net until harvesting. Although the current construction methods have certain advantages in terms of cost, the disadvantages in terms of wind resistance are quite obvious. That is to say, although the prior art isolation device has a certain windproof characteristic, its windproof performance is quite limited, and for the condition that wind power is great, the prior isolation device may not withstand, even the lodging causes more serious injury to crops, and more causes economic burden to the reconstruction isolation device.

These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment, given as a non-limiting example, with reference to the accompanying drawings.
It should also be understood that, although the invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of the invention, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
The above and other aspects, features and advantages of the present invention will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
An embodiment of the invention provides an isolation device applied to plant protection, which comprises a plurality of isolation units which can be enclosed to form an enclosed area (not shown) and a top insect-proof net (not shown) covering the enclosed area, wherein, fig. 1 and fig. 2 are schematic structural diagrams of one isolation unit, as shown in the figure, each isolation unit comprises a supporting mechanism 1 and a side insect-proof net 2 arranged on the supporting mechanism 1, the supporting mechanism 1 comprises a plurality of buried upright rods 13 which are arranged side by side, a bottom frame body 12 close to one side of the ground and a top frame body 11 close to the isolation height are arranged in parallel among the plurality of buried upright rods 13, two ends of the bottom frame body 12 and the top frame body 11 are respectively provided with a tensioning upright rod 16 parallel to the buried upright rods 13, the tensioning upright rods 16 are connected with the end parts of the bottom frame body 12 or the top frame body 11 through tensioning screws 17, the side insect-proof net 2 is arranged on the tensioning vertical rods 16 at two sides in a tensioning manner. As shown in fig. 1 and 2, a plurality of buried upright stanchions 13 are arranged at intervals and buried underground, a bottom frame body 12 and a top frame body 11 are fixed on the buried upright stanchions 13 and used for tensioning the side insect-proof net 2, compared with the prior art, the side insect-proof net 2 is directly covered on a greenhouse frame, and the bottom is compacted by soil, the invention has better structural strength, not only realizes the basic physical isolation and the insect pest control function, but also can resist stronger crosswind, and the isolated crops can avoid lodging caused by strong wind through the attenuation of the insect-proof net to the wind power.
In the above embodiment, as shown in fig. 3 and 5, the bottom frame 12 and the top frame 11 are connected to the buried vertical rod 13 by a lock 14. Specifically, the locking buckle 14 at least comprises a first fastener 141, and the first fastener 141 comprises a first arch 1411 and a second arch 1412 which are oppositely arranged and used for clamping the buried vertical rod 13. Of course, for better gripping, as shown in fig. 5, in some embodiments, a slot 1413 is provided at a position of the first arch 1411 and/or the second arch 1412 corresponding to the buried vertical rod 13, and a second fastener 142 assisting in clamping the buried vertical rod 13 is provided in the slot 1413. The bottom frame 12 or the top frame 11 can be firmly connected with the buried upright 13 by the auxiliary clamping of the second fastener 142. In some implementations, the second fastener 142 can be configured to be coupled at both ends to the first fastener 141 by a first bolt 1422 and a second bolt 1423, and for real-time adjustability, the bolt at one end, such as the second bolt 1423, can be configured to be secured through an open slot 1424. Since the first bolt 1422 and the second bolt 1423 simultaneously pass through the slot 1413, when the first bolt 1422 and the second bolt 1423 are loosened, they can be displaced within the slot 1413, and at this time, for example, the second bolt 1423 can slide out of the open slot 1424, so as to release the auxiliary clamping of the buried vertical rod 13, and facilitate the adjustment of the position of the latch 14 on the buried vertical rod 13. As shown in fig. 6, for the second fastening member 142, in order to achieve auxiliary clamping of the buried vertical rod 13, it is necessary that the second fastening member and the buried vertical rod 13 do not slide relatively as much as possible, and therefore, preferably, a plurality of convex teeth 1421 are provided on a side of the second fastening member 142 contacting the buried vertical rod 13.
In the present invention, the bottom frame 12 and the top frame 11 are used as main supporting members, and the structural strength thereof will directly affect the overall wind resistance. Considering that the integral support member 2 should have structural integrity when receiving side wind loads, as shown in fig. 2, 3 and 6, the bottom frame 12 is preferably identical in structure to the top frame 11 and includes first profiles 111 nested inside each other and located on opposite outer sides and second profiles 112 located on opposite inner sides. By adopting a two-layer nesting mode, the problem of brittle fracture which is easy to occur when a single-layer section is formed and faces strong wind can be avoided.
In addition, as a further improvement, each of the first profile 111 and the second profile 112 has a straight section (not labeled) at the middle position and a bend at the two ends, specifically, see the first bend 1111 and the second bend 1121 shown in fig. 2, 3 and 6; and, the straight section of the first section bar 111 and the straight section of the second section bar 112 are fixedly connected, and the plurality of latches 14 are disposed on the straight sections of the two. Meanwhile, in the present invention, in order to prevent the first profile 111 and the second profile 112 from resonating under the wind. In practice, the stiffness of the first profile 111 and the second profile 112 is different, for example the first profile 111 has a first stiffness and the second profile 112 has a second stiffness different from the first stiffness. Furthermore, the first stiffness is preferably greater than the second stiffness in view of the nested configuration of the two. Since the second profile 112 is nested in the first profile 111 and has a smaller structural rigidity, the second profile 112 can be deformed within its bearing range when resisting wind, and the first profile 111 provides an integral rigid support. When the wind power is larger, the first section bar participates in deformation energy absorption at the same time. Compared with a completely concrete cast structure, the proper deformation energy absorption structure can more easily keep the whole structure complete. In addition, although the first profile 111 and the second profile 112 have different stiffness in the preferred embodiment, they can be made of the same material, such as a profile.
In the exemplary embodiments of the present invention provided above, a water collection tank 3 may be further combined, as shown in fig. 1 to 6, the water collection tank 3 is disposed at both ends of the bottom frame 12 and below the side insect-proof net 2. The bottom of the water collecting tank 3 is provided with a plurality of water falling holes 31, so that in the night, in the closed crop planting interval, water vapor generated by the transpiration of sunshine in the daytime, water vapor in the air at night and water vapor generated by the respiration of plants can be captured by the side insect-proof net 2 and condensed into water drops. The part of the water droplets further accumulates to flow into the water collection sump 3. The water collecting tank 3 is provided with a water falling hole 31, so that water can be further uniformly collected by means of a water falling pipe for irrigation or other purposes. However, for arid regions, the downpipe may not be used, and the collected water may be directly dropped into the ground through the downholes 31. In this embodiment, as a further improvement, the water collecting tank 3 can be connected to both ends of the bottom frame 12 by the fixing buckles 15, specifically, the fixing buckles include the second fixing member 152 in the shape of an inverted "L" and the first fixing member 151 with a small amount of curvature, and of course, it is necessary to form the locking grooves 32 by recessing both ends of the water collecting tank 3, and one end of the second fixing member 152 is inserted into the locking groove 32, and the other end is connected to the first section bar 111 by the first fixing member 151.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
