A liftable anti-bird grid support bar for millet test

Abstract

The invention relates to a liftable birdproof network rack supporting rod for a millet test. The liftable birdproof network rack supporting rod belongs to the field of birdproof technology. The supporting rod comprises a fixed rod and an adjusting rod. The bottom of the fixed rod is flat and is inserted into soil for fixation. The upper end of the fixed rod and the lower end of the adjusting rod are sleeved and fixed through a height adjusting device. The height adjusting device comprises a positioning hole on the fixed rod and two adjusting holes on the adjusting rod. The two adjusting holes are respectively a mounting hole and a using hole and are respectively in plugged fixation with the positioning hole through a pin. Mounting height adjustment and use height adjustment can be performed on the supporting rod. Pin adjustment can improve a corrosion condition. The upper end of the adjusting rod is provided with a stainless steel ball with insertion plates. A bird preventing net is laid on the upper end surface of the stainless steel ball. The lower part of the fixed rod is also provided with a water leaking hole. Corrosion caused water deposit in the rod can be prevented. The liftable birdproof network rack supporting rod has functions of quickly adjusting the height of the bird preventing net, realizing quick entering of equipment and personnel into a test field, improving operation efficiency and realizing no easy bird preventing net damage by a hook.

Description

technical field [0001] The invention belongs to the field of anti-bird technology, and relates to anti-bird equipment for crops, in particular to a liftable anti-bird grid support rod for millet testing. Background technique [0002] The millet test generally has a large amount of materials but a small area, and bird damage is one of the main factors affecting the millet test. In recent years, people have taken some measures to prevent and control bird damage in millet, such as artificial bird repelling, sound bird repelling, chemical bird repellent agent repelling birds, etc., but these methods are only effective for a short period of time, and the effect is not very satisfactory. How to protect birds and reduce millet bird damage, the effect is better only to erect bird nets, but most of the grid support bars currently used are galvanized pipes, which mainly have the following problems: (1) The height is fixed and cannot be lifted. In order to facilitate the erection of a...

Problems solved by technology

In recent years, people have taken some measures to prevent and control bird damage in millet, such as artificially repelling birds, sound repelling birds, chemical bird repellents, etc., but these methods are only effective in a short period of time, and the effect is not very satisfactory

How to protect birds and reduce millet bird damage, the best effect is to erect bird nets, but most of the grid support rods currently used are galvanized pipes, which mainly have the following problems: (1) The height is fixed and cannot be lifted

In order to facilitate the erection of anti-bird nets, the height of this kind of nets is generally small, which is inconvenient to carry out field experiments in the later stage. If the height is increased, the difficulty of erecting anti-bird nets will be greatly increased

(2) The height-adjustable grid support rods are all fixed with holes and screws. After using in the rainy season, it will cause serious corrosion and it is not convenient for future use.

(3) Rainwater stays in the pipe for a long time, causing erosion to the inner wall of the pipe

(4) The fixing device of the iron wire on the anti-bird net frame is easy to hang the net, and it is inconvenient to lay
