Embodiment Construction

[0016] Such as figure 1 As shown, a wheat precision seeder with single and double rows of seedlings is composed of a frame 4, a ground wheel 7, a seed box 1, a hole-type seed meter, a seed tube 5, a ditch opener 8, and a transmission device 6. . Among them, the hole-type seed metering device is divided into a single-row seed metering device 2 and a double-row seed metering device 3. The single-row seed metering device 2 is provided with two circles of staggered holes, and each circle has 36 holes; the single-row seed metering device A seeding pipe 5 is connected below the device 2; the double-row seed meter 3 is provided with four rows of uniformly staggered holes, and the number of holes in the four rows is equal to the number of holes in the two rows of the single-row seed meter. There are 18 holes in the circle; two seeding pipes 5 are connected under the double-row seed meter 3; the horizontal average distance between the single-row opener and the double-row opener is b=2...

Abstract

The invention discloses a seedling zone single double-row wheat precision seeder; a seed metering device comprises a single-row seed metering device and a double-row seed metering device; the single-row seed metering device is provided with two rows of soil holes which are arranged staggeredly; a seeding pipe is connected to the lower part of the single-row seed metering device; the double-row seed metering device is provided with four rows of soil holes which are arranged uniformly and staggeredly; the number of the four-row soil holes is equal to the number of the two-row soil holes of the single-row seed metering device; two seeding pipes are connected to the lower part of the double-row seed metering device; an average transverse distance between a single-row furrow opener and a double-row furrow opener is 20 cm, and a transverse center distance of the double-row furrow opener is 5 cm. The invention effectively reduces the crowding phenomenon between plants, improves the habitat conditions, enhances the tillering capability, realizes the combination of promotion and inhibition, greatly increases the population self-regulation capability, is simple and practical in operations, has low cost, conforms to traditional plantation habits, and is easy to be accepted and popularized by the masses.

Description

technical field [0001] The invention belongs to agricultural machinery, especially sowing machinery. Background technique [0002] Its structure of existing wheat planter both at home and abroad is substantially identical, all is made up of frame, ground wheel, seed box, seed metering device, planting pipe, ditch opener, transmission. There are evenly arranged seed holes on the surface of the seed meter. When the transmission ratio of the transmission device is constant, the number of seed holes determines the plant spacing of sowing, and the setting distance of the opener determines the row spacing and single and double row form of sowing. The tractor-powered seeder is equipped with more than 5 to 10 openers, and each opener only sows a row of seeds, which is called "single-line seeder". Due to the fact that the seeds on a single line are too dense under the condition of a certain amount of seed per mu, it has a certain inhibitory effect on wheat tillering. Therefore, a ki...
