Seed sowing machine

Abstract

The invention provides a transplanter which is used for matching with the power machinery of a hand tractor, etc., and applicable for hole seeding of corn and soybean. The transplanter of the invention comprises a guide wheel, a pull bar, walking wheels, a seed manure box and a duck-billed transplanter. The transplanter is characterized in that: the seed manure box is fixedly connected on a seed manure bracket, a seed control plate is arranged between the bottom part of the seed manure box and the upper plate of the seed manure bracket, the seed mating limited port of the seed control plate is matched with a seed mating cam which is fixedly connected on a seeding displacement rack, the fixed mouth of the duck-billed transplanter is fixedly connected on the seeding displacement rack, the duck-billed transplanter is matched with the seeding limited port of the lower plate of the seed manure bracket, the driving chain wheel on a driving shaft is connected with the driven chain wheel of a driven shaft, a cam group which is fixedly connected with the driven shaft is contacted with a bending arm which is fixedly connected on a joint shaft, the bending arm is coaxially and fixedly connected with a swing arm which is articulated on the seeding displacement rack. The transplanter of the invention has the advantages of reasonable structure, adjustable seeding depth, plant spacing and spacing between ridges, reliable action, long service life, high working efficiency, good seeding quality, etc.

Description

technical field [0001] The utility model relates to a planter in the field of agricultural machinery, in particular to a planter which is used in conjunction with power machinery such as a walking tractor and is suitable for corn and soybean hole planting operations. Background technique [0002] The existing hand-push small seeder has a ground wheel hinged on the fixed shaft, the empty stomach in the ground wheel is a seed and fertilizer box, and several seeds and fat duck mouths for hole sowing are arranged on the circumferential wall of the ground wheel. The movable beak of the species and the fat duckbill is hinged with the connecting rod, and the connecting rod is hinged with the crank arm that opens the movable mouth of the kind and the fat duckbill. When the crank arm is in contact with the positioning rod fixed on the fixed shaft, the positioning rod will deflect the crank arm around the hinge axis to set the angle, and the crank arm will pull the moving mouth of the...

AI Technical Summary

Problems solved by technology

Its shortcomings are: unreliable action, easy to break down, and frequent maintenance; it cannot be matched with walking tractors and other power machinery to achieve traction operations, and can only be pushed by human hands, and can only achieve single-row planting and fertilizer hole sowing operations. Low efficiency and high labor intensity

[0003] The existing multi-functional seeder used for farming with power machinery such as walking tractors can complete operations such as plowing furrows, sowing seeds, sprinkling fertilizer, covering soil, and compacting in one device. Although it has complete functions, its structure is complicated and it is easy to produce Failure, high manufacturing and use costs, long operation process, poor quality of planting, and inability to realize hole planting and planting operations
