Description

Technical Field

[0001] The utility model belongs to the technical field of bulletin boards, and in particular relates to an agricultural English bulletin board for an experimental field. Background Art

[0002] In agricultural research, in order to explore and verify the superiority of a certain production technology or crop variety, field trials are usually conducted to study it. In general, repeated field plot trials are used. In addition, in order to promote certain advanced agricultural technologies or excellent varieties, field demonstrations are also required to be carried out first. In the process of field trials and demonstrations, different treatment plots must be distinguished and marked. Currently, most of them use wooden signs of appropriate sizes, fix wooden poles on the back of the wooden signs, and then paste paper with plot descriptions on the wooden signs. Finally, the wooden signs are inserted into the corresponding plots for identification. However, the existing technology cannot change the content of the bulletin board as a whole, and the optimization of bird repelling is not perfect.

[0003] Application number "CN201120009458.5" records "a combined portable ground-inserted test field sign, comprising a sign and a ground-inserted pole, characterized in that the sign is a hollow wooden sign made of two rectangular plywood panels of the same size and a thin wooden frame nailed and glued together; a rectangular socket is provided in the middle of one long side of the sign, and the socket diameter is slightly larger than the cross-sectional dimension of the ground-inserted pole; the ground-inserted pole is a long pole with a rectangular cross-section, the upper end of which can be inserted into the socket of the sign, and the other end of the ground-inserted pole is sharpened into a pyramid shape for easy insertion into the field."

[0004] The above patent is based on a combination of portable ground-inserted test field identification signs. When in use, a paper with a description of the community is pasted on the identification sign. In the corresponding community, the tip of the ground-inserted rod is inserted vertically downward into the ground. Then, the socket of the identification sign is aligned with the upper end of the ground-inserted rod, and the identification sign is installed downward on the ground-inserted rod, finally combining into a complete test identification sign.

[0035] See also Figure 2 , the announcement content board 4 is arranged on the main body;

[0036] See also Figure 3 The limiting mechanism is arranged on the main body. Specifically, the limiting mechanism includes a limiting block 5 and a cross socket A6. The limiting block 5 is slidably arranged at the inner wall port of the slide groove 3, and the cross socket A6 is opened at the top of the limiting block 5 and penetrates to the bottom;

[0037] See also Figure 4 , the fixing mechanism is arranged on the limiting mechanism, specifically, the fixing mechanism includes a cross socket B7 and a cross pin 8, the cross socket B7 is opened at one end of the top of the billboard body 1 and is close to the cross socket A6, the other end of the cross socket B7 penetrates to the bottom of the billboard body 1, and the positions of the cross socket A6 and the cross socket B7 are aligned with each other, and the cross pin 8 is slidably arranged on the inner walls of the cross socket A6 and the cross socket B7; and

[0038] See also Figure 5 The bird-repelling mechanism is arranged on the main body. Specifically, the bird-repelling mechanism includes a fixed column 9 and a thin rope 10. The fixed column 9 is symmetrically provided with two fixed columns 9, which are respectively fixed at the two ends of the top of the billboard body 1, and the two ends of the thin rope 10 are respectively fixed at the top of the two fixed columns 9.

[0039] See also Figure 3 The announcement content board 4 is slidably arranged on the inner wall of the slide groove 3.

[0040] See also Figure 5 A support rod 2 is fixedly provided at the bottom of the outer wall of the bulletin board body 1.

[0041] In the present embodiment: by sliding the limit block 5 at the inner wall port of the slide slot 3, the cross socket A6 is opened at the top of the limit block 5 and penetrates to the bottom, the cross socket B7 is opened at one end of the top of the billboard body 1 and is close to the cross socket A6, the other end of the cross socket B7 penetrates to the bottom of the billboard body 1, and the positions of the cross socket A6 and the cross socket B7 are aligned with each other, and the cross pin 8 is slidably set on the inner walls of the cross socket A6 and the cross socket B7, it is effectively realized that the content of the billboard can be changed at any time, reducing the overall limitations of the device.

[0042] By fixing two fixing posts 9 at the two ends of the top of the billboard body 1 respectively, and fixing the two ends of the thin rope 10 at the top of the two fixing posts 9 respectively, the birds can be driven away without causing any harm to the birds themselves.
