Automatic agricultural machine hidden positioning antenna based on Beidou positioning

Abstract

The invention provides an automatic agricultural machine hidden positioning antenna based on Beidou positioning, and relates to the field of agricultural machine positioning antennas. An external connection wire hole is formed in the rear side of the outer shell, eight bolts are installed on the periphery of the front end of the outer shell in a surrounding mode, and the outer shell is embedded inthe outer wall of the agricultural machine through the bolts. The inner shell is located in the outer shell, an inner connecting wire hole is formed in the rear side of the inner shell, and the innerconnecting wire hole in the rear side of the inner shell is communicated with the outer connecting wire hole in the rear side of the outer shell; and the inner walls of the left side and the right side of the inner shell are each provided with an inner sliding groove, and the inner walls of the left side and the right side of the front end of the inner shell are each provided with a rotating groove. The telescopic frame drives the antenna assembly plate to move to the outside of the front end of the inner shell, so that the Beidou antenna mounted at the front end of the antenna assembly plateis completely exposed to the outside and is prevented from being shielded by an agricultural machine body, the receiving and transmitting effects of the Beidou antenna are guaranteed, and the signalreceiving stability of the Beidou antenna is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery positioning antennas, and more specifically relates to a hidden positioning antenna for automatic agricultural machinery based on Beidou positioning. Background technique [0002] Since the 1990s, precision agricultural technology has been considered by the international agricultural science and technology community as one of the leading technologies to achieve sustainable agricultural development in the 21st century. The automatic navigation of agricultural machinery is an important part of modern intelligent agricultural machinery and has broad fields. Development prospects, as a core key technology of precision agriculture, automatic navigation of agricultural machinery is widely used in agricultural production processes such as farming, sowing, fertilization, spraying, and harvesting. At present, in agricultural machinery navigation systems, Beidou positioning antennas are genera...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a hidden positioning antenna for automatic agricultural machinery based on Beidou positioning, to solve the problem that the existing similar Beidou positioning antenna for agricultural machinery has poor protection effect on the antenna itself, in order to ensure the signal reception of the antenna Strength, the antenna is generally installed outside the agricultural machinery body, the antenna is exposed outside the agricultural machinery body for a long time, it is easy to accelerate aging, shorten the service life of the Beidou antenna, a small number of antennas are installed inside the agricultural machinery body, although the antenna can be protected through the agricultural machinery body, but the antenna is easy Covered by the shell of the agricultural machinery body, the antenna signal reception strength is weakened, which in turn affects the positioning and operation of the agricultural machinery.
