Problems solved by technology

At present, most of the seeders in the domestic seeder market are external grooved wheel seed metering parts. Inhomogeneity, precision seeding still difficult to achieve
In addition, due to the limited working principle of the seed metering device of the domestic seeder, the seeding efficiency is very low
Most of the domestic seeders are still unable to complete the joint operation, and the operation efficiency of the whole machine is low

Embodiment 1

[0019] see figure 1 and figure 2 , a kind of air-suction seeder provided by the present invention comprises frame 1, and described frame 1 comprises beam 1a, fertilization support 1b, sowing support 1c, ditch opener support 1d and hanger 1e, and described fertilization support 1b It is fixed symmetrically above the crossbeam 1a axially, on which a fertilizer box 2 is supported, and the sowing brackets 1c are more than one group, which are arranged at intervals below the crossbeam 1a, on which a seed box 3 is supported, and the opening The trencher support 1d is a parallel four-bar linkage mechanism, installed at intervals below the axial direction of the beam 1a, and correspondingly connected with the sowing support 1c, and the side of the trencher support 1d near the crossbeam 1a is equipped with a disc type fertilization opener 4. The disc type fertilization ditch opener 4 is connected with the fertilizer box 2 through the fertilizer delivery pipe 5, and the side of the di...

Embodiment 2

[0027] In order to enable the planter in embodiment 1 to carry out ditching, fertilization, and seeding operations, the joint operation of weeding and covering soil, suppression, and weeding can be carried out simultaneously. A depth-limiting wheel 15 can be fixedly arranged below the sowing support 1c on one side of the near-disc type fertilization ditch opener 4, and a covering soil suppression combination 16 is fixedly arranged below the sowing support 1c on the side of each depth-limiting wheel 15 away from the beam 1a. A grass-distributing mechanism 17 is fixedly arranged below the sowing support 1c near the side of the beam 1a.

Embodiment 3

[0029] In order to ensure the consistency of the sowing row spacing, markers 18 can be installed at both ends of the beam 1a, and the markers 18 can be controlled by hydraulic pressure.

Abstract

The invention relates to a pneumatic seeder. The pneumatic seeder comprises a fertilizing mechanism, more than one group of seeding mechanisms, a trenching mechanism and a land wheel mechanism, wherein the seeding mechanisms are arranged at intervals in sequence, and precise seed metering is realized by utilizing a pneumatic seed metering device. The pneumatic seeder is also provided with a grass dividing mechanism, a depth limiting wheel, an earthing and pressing wheel and the like. The pneumatic seeder can be used for realizing precise single-grain dibble seeding of crops such as corn, sorghum, beans and sugar beet (coated seeds), can be used for trenching, fertilizing, seeding, earthing and pressing operations simultaneously in work to realize joint operation.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an air suction seeder. Background technique [0002] At present, in our country, the development and research of precision seeder began in the early 1970s, and it has not been widely used so far. Compared with foreign countries, there is still a considerable gap in my country's precision seeding technology. At present, most of the seeders in the domestic seeder market are external grooved wheel seed metering parts. Inhomogeneity, precision seeding is still difficult to achieve. In addition, due to the limited working principle of the seed metering device of the domestic seeder, the seeding efficiency is very low. Most of the domestic seeders are still unable to complete the joint operation at present, and the operation efficiency of the whole machine is low. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a kind o...
