Problems solved by technology

[0002] Most of the grain crop sowing devices in the prior art have a narrow application range, a single variety suitable for sowing, or a complex structure and high cost, making it difficult to popularize on a large scale
In particular, due to the fixed structure of the frame of the existing planter, when the ground undulates, the opener and the pressing wheel cannot maintain normal contact with the ground, and the phenomenon of ridge breakage occurs during sowing.

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] figure 1 As shown, the seeder in the prior art is usually connected by a rigid connection mechanism between the power mechanism and the seeding mechanism, such as figure 1 Fixed plate 1 shown. This rigid connection mechanism is suitable for working on flat land. When encountering undulating and uneven cultivated land, uneven sowing and unrealistic suppression will occur, resulting in lack of seedlings and broken ridges. The method adopted by the present invention is to set a four-bar linkage mechanism 3 between the fixed plate 1 and the sowing mechanism, and utilize the characteristics of the four-bar linkage mechanism to make the following sowing mechanism adjust with the fluctuation of the ground, and the situation of leaving the ground will not be reproduced . As shown in the figure, the four-bar linkage mechanism 3 is connected with the fixed plate 1 th...

Abstract

The invention relates to a five cereals precision seeder which comprises a fixing plate and a sowing mechanism and is characterized in that a four-bar mechanism is arranged between the fixing plate and the sowing mechanism. For the five cereals precision seeder, the four-bar mechanism is adopted for connecting a traction mechanism and the sowing mechanism, and a four-bar principle is utilized for guaranteeing that when the sowing mechanism encounters an uneven ploughing surface, the sowing mechanism and the ground are in normal contact, so that sowing can be carried out normally, and a press wheel also can run normally.

Description

technical field [0001] The invention relates to a sowing device, in particular to a sowing device capable of sowing corn, millet, sorghum, soybean and other food crops. Background technique [0002] Most of the grain crop seeding devices in the prior art have a narrow application range, a single variety suitable for sowing, or complex structures and high costs, and are difficult to be popularized on a large scale. Especially because the frame of the existing planter adopts a fixed structure, when the ground undulates, the opener and the pressing wheel cannot keep in normal contact with the ground, and the phenomenon of ridge breaking occurs in sowing. Contents of the invention [0003] The present invention aims at the problem that above-mentioned prior art exists, has designed a kind of precision sowing machine of five grains, has solved above-mentioned problem. [0004] A five-grain precision sower according to the present invention includes a fixed plate and a sowing m...
