Abstract

The utility model relates to a multi-function seeder, composed of rollers, drill barrow legs, handles, a hopper, a seeding pipe, an adjustable supporting frame and a seeding part. An eccentric crank of the seeding part is driven to rotate by the rollers in order to drive an inner and outer rotary disk to move to and fro to enable seeds to fall uniformly. The aim of dibbling achieved by adjusting a stroke screw on the eccentric crank to control seeding quantity or by enabling a dibbling tooth guiding disc to rotate through a mixing claw nail. Three through holes are arranged at the place of 120 of a seeding disc. Seed scattering holes on the inner rotary disc, or the outer rotary disc or the dibbling tooth guiding disc are communicated with the three through holes. When seeding is stopped, the three seed scattering holes are covered by a seed closing triangle fork. The utility model has the advantages of simple operation and convenient operation.

Description

Multifunctional seed drill

The utility model belongs to field of agricultural machinery, is specifically related to a kind of multifunctional seed drill.

At present, China has quite a few rural area also not realize mechanization, several people or draw an animal-drawn seed plough in front with livestock when the peasant sows wheat, corn, a people buttresses an animal-drawn seed plough in the back and sows, in the process of walking about, the back holds up the people of an animal-drawn seed plough to shake while walking, to seed is planted underground.There is following problem in this cultivation mode: 1. be under the situation of unit farming with the family at present, adopt several people or livestock to draw an animal-drawn seed plough not current; 2. traditional an animal-drawn seed plough since need that artificial control sows what, seed can not well-proportionedly be broadcast underground, causes waste and also is unfavorable for the growths of crops.

In addition, mechanization sowing needs the power-equipment traction, invest greatlyyer, and is not suitable for the use in small size arable lands such as mountain area.

The purpose of this utility model provides a kind of semi-automatic multifunctional seed drill simple to operate.This sower comprises roller 1, an animal-drawn seed plough leg 6, handgrip 8, hopper 24, sow pipe 27 and adjustable supporter 29, it is characterized in that:

A) roller 1 is contained in the front end of adjustable supporter 29 by the roller shaft that is fixed together with it, the two ends of roller shaft are fixed with the eccentric mechanism 2 that becomes eccentric motion with roller shaft respectively, 15, and be arranged in two eccentric mechanisms (2 on the roller shaft, 15) angle between is 90 °, eccentric mechanism 2 is successively through connecting rod 3, rocking bar frame 4, adjusting rod 5 flexibly connects with outer rotary disk 7, eccentric mechanism 15 is successively through connecting rod 14, rocking bar frame 13, movable connecting rod 12, adjusting rod 11 flexibly connects with interior rotary disk 10, outer rotary disk 7 is placed in the seed tray 9 with interior rotary disk 10 and back and forth is rotatably assorted around seed tray axle 21 at grade, seed tray 9 is contained in the upper end of adjustable supporter 29, on 120 ° of positions of seed tray 9, have three through holes, in, outer rotary disk 10, diffusing kind of hole 25 on 7 communicates with three through holes 34, closing kind of triangle fork 22 covers at the place, diffusing kind of hole that communicates with three through holes 34 and is fixed on the hopper base 23, hopper base 23 is fixedlyed connected with seed tray 9, and three through holes 34 on the seed tray 9 are connected with three an animal-drawn seed plough legs 6 by the pipe 27 of sowing;

B) roller 1 is contained in the front end of adjustable supporter 29 by the roller shaft that is fixed together with it, several are mixed pawl nail 20 and are fixed on the wheel hub of roller 1, program request is mixed pawl 16 and is connected with dibbling gear guiding plate 19 by program request guide rod 17, program request is smash chain wheel 19 and is placed in the seed tray 9 around 21 rotations of seed tray axle, seed tray 9 is contained in the upper end of adjustable supporter 29, on 120 ° of positions of seed tray 9, have three through holes, the diffusing kind of hole 25 that program request is smash on the chain wheel 19 communicates with three through holes 34, closing kind of triangle fork 22 covers at the place, diffusing kind of hole that communicates with three through holes 34 and is fixed on the hopper base 23, hopper base 23 is fixedlyed connected with seed tray 9, three through holes 34 on the seed tray 9 are connected with three an animal-drawn seed plough legs 6 by the pipe 27 of sowing, and spring 28 is fixed between frame and the program request stamp stem 17.

This sower has following advantage:
