[0003] At present, the commonly used crop protection measures on the market are as follows:

[0004] Covering the crops directly with nets, however, the nets will touch the crops, which may cause damage to the crops. At the same time, insects, birds, etc. can still touch the crops, and the protection performance is poor;

[0069] In other embodiments, the first plug-in portion 212 and the third plug hole 211 may also be connected by interference fit, which can also achieve reliable connection of adjacent vertical support rods 21 together.

[0070] See also Figure 6In one embodiment, the third elastic connecting member 213 is provided with a third elastic sheet 2131 and a third connecting protrusion 2132, the third elastic sheet 2131 is provided with two third elastic arms 21311, the first ends of the two third elastic arms 21311 are connected, and the second ends of the two third elastic arms 21311 are separated, the second end of one of the third elastic arms 21311 is abutted against one of the two opposite inner side walls of the first plug-in portion 212, and the second end of the other third elastic arm 21311 is abutted against the other of the two opposite inner side walls of the first plug-in portion 212, the third connecting protrusion 2132 is connected to the second end of one of the third elastic arms 21311, the third connecting protrusion 2132 has a third retracted state and a third extended state, and the third connecting protrusion 2132 cooperates with the third connecting hole 214. When the third spring 2131 is in the state of being pressed, the third spring 2131 is pressed against the third connecting protrusion 2132, and the third spring 2131 is pressed against the third connecting protrusion 2132, so that the third spring piece 2131 is compressed and accumulates potential energy. When the third connecting protrusion 2132 is not subjected to pressing force, the third spring piece 2131 releases the potential energy, so that the third spring arm 21311 connected to the third connecting protrusion 2132 moves in the direction away from the other third spring arm 21311, so that the third connecting protrusion 2132 is reset to the third extended state. As the third spring piece 2131 is provided with two third spring arms 21311, the first ends of the two third spring arms 21311 are connected, and the second ends of the two third spring arms 21311 are separated, that is, the third spring piece 2131 is V-shaped. The second end of one of the third elastic arms 21311 abuts against one of the two opposite inner walls of the first plug-in portion 212, and the second end of the other third elastic arm 21311 abuts against the other of the two opposite inner walls of the first plug-in portion 212, so that the third spring piece 2131 can be clamped with the first plug-in portion 212. Therefore, during installation, the maximum cross-sectional area of ​​the third spring piece 2131 can be reduced to a level that allows it to penetrate into the interior of the first plug-in portion 212 by pinching the second ends of the two third elastic arms 21311 with fingers. The third spring piece 2131 located in the interior of the first plug-in portion 212 is reset to fit tightly against the inner wall of the first plug-in portion 212 under the action of its own elastic force, thereby achieving reliable fixing of the third spring piece 2131 in the first plug-in portion 212, thereby achieving reliable installation of the third elastic connector 213 on the vertical support rod 21, and the installation operation is simple and the installation efficiency is high.

[0071] In other embodiments, a spring may be used to replace the third elastic leaf 2131 .

In this way, during installation, the adjacent transverse support rods 31 can be connected together by inserting the second plug portion 312 into the fourth plug hole 311, which is simple to install and has high installation efficiency.

[0073] In one embodiment, the grid further comprises:

[0074] A plurality of connectors (not shown in the figure) are arranged in sequence around the vertical center line of the connecting base 1, and each connector connects the outer ends of the corresponding adjacent beams 3 together to increase the structural strength of the beams 3 so that the beams 3 can reliably support the mesh cover 4.

[0075] In one embodiment, the connector is a structure made of nylon;

[0076] The outer end of the crossbeam 3 is provided with a rope threading hole 33 and a positioning groove 34. The rope threading hole 33 passes through the crossbeam 3 on the left and right sides. The rope threading hole 33 is for the connector to pass through. The positioning groove 34 is located on the outer end of the crossbeam 3. The positioning groove 34 connects the left and right ends of the rope threading hole 33, and the positioning groove 34 cooperates with the connector. In this way, the rope threading hole 33 is passed through one end of the connector and then cooperates with the positioning groove 34, and one end of the connector is tied together with the rest of the connector to achieve the fixation of the connector and the crossbeam 3. The connection operation is simple and the connection efficiency is high. The setting of the positioning groove 34 can play a positioning role on the connector, which can improve the connection stability between the connector and the crossbeam 3, and make the connector not easy to separate from the crossbeam 3. In addition, the connector made of nylon material is light and will not increase the overall weight of the grid frame too much, which is convenient for the grid frame to be erected on crops and is more convenient to install. At the same time, the connector made of nylon material has a long service life and can be repeatedly used, which can reduce maintenance costs.

[0077] In one embodiment, the connection base 1 is a structure made of aluminum, and the vertical beam 2 and the horizontal beam 3 are structures made of fiberglass. The connection base 1 made of aluminum is corrosion-resistant and has a light overall weight, so that the connection base 1 has a long service life and is light enough. At the same time, the vertical beam 2 and the horizontal beam 3 made of fiberglass are resistant to extreme temperatures, UV rays, and corrosion, and have a light overall weight, so that the vertical beam 2 and the horizontal beam 3 have a long service life and are light enough, so that the overall service life of the grid is long and light enough, and it is easy to install. At the same time, it will not put pressure on the crops, thereby avoiding affecting the growth of the crops.

[0078] In other embodiments, the connecting base 1 , the vertical beam 2 and the horizontal beam 3 may all be structures made of plastic material.

The inner ends of the second connection parts 12 are connected to the first connection parts 11 to increase the structural strength of the second connection parts 12, so that the second connection parts 12 can be reliably connected to the beam 3.
