Example Embodiment

[0018] Example 1

[0019] See figure 1 and figure 2 , The present invention provides an air-suction planter, including a frame 1, the frame 1 includes a beam 1a, a fertilization support 1b, a seeding support 1c, a furrow opener support 1d and a suspension frame 1e, the fertilization support 1b It is symmetrically fixed on the upper part of the crossbeam 1a in the axial direction, and the fertilizer box 2 is supported on it. The seeding support 1c is a group of more than one group, which are arranged at intervals below the crossbeam 1a, and the seed box 3 is supported on it. The ditcher bracket 1d is a parallel four-bar linkage mechanism, which is installed at intervals below the crossbeam 1a and is connected to the seeding bracket 1c. The ditcher bracket 1d is equipped with a disc type fertilization opener on the side of the crossbeam 1a. 4. The disc type fertilizing opener 4 is connected to the fertilizer box 2 through the fertilizer pipe 5, and the shovel type seeding opener 6...

Example Embodiment

[0026] Example 2

[0027] In order to enable the planter in Example 1 to perform combined operations of weeding, soil covering, suppression, and weeding at the same time when ditching, fertilizing, and sowing operations. A depth-limiting wheel 15 can be fixedly installed under the seeding support 1c on one side of the near-disc fertilization opener 4, and a soil-covering suppression combination 16 can be fixedly installed under the seeding support 1c on the side close to each depth-limiting wheel 15 and away from the beam 1a. A grass dividing mechanism 17 is fixedly arranged under the seeding support 1c on the side close to the cross beam 1a.

Example Embodiment

[0028] Example 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...
