Runway-shaped hanging-cup-type zero-speed planting mechanism

Abstract

The invention relates to a runway-shaped hanging-cup-type zero-speed planting mechanism. The planting mechanism comprises two groups of chain wheels, track chains, a plurality of hanging cups, an intermittent automatic seedling placement device, a seedling feeding driving track, a mounting rack and a transmission device, wherein the mounting rack is a cubic framework, and the seedling feeding driving track is mounted on the rear side of the mounting rack; two groups of the chain wheels are respectively mounted on the left and right sides in the mounting rack, the two track chains are respectively mounted on two group of the chain wheels, and the chain wheels are connected through the transmission device; the hanging cups are hinged to the two chain wheels at equal intervals; and a seedling receiving hopper is connected to a crossbeam on the top end of the rear side of the mounting rack, an intermittent seedling placement hole is formed in the bottom of the seedling receiving hopper, two rotating baffles below the seedling receiving hopper are respectively hinged with the seedling receiving hopper and are meshed with each other through tooth-shaped structures, a reset spring I is mounted between the two rotating baffles, and a handle is welded below one rotating baffle. By utilizing the runway-shaped hanging-cup-type zero-speed planting mechanism, the zero-speed planting is realized, and the increase of the perpendicularity of the seedlings is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanized transplanting, and in particular relates to a track-shaped hanging cup type zero-speed planting mechanism. Background technique [0002] Seedling transplanting is an extremely important part of vegetable production and planting, and it has many advantages over direct sowing and planting of vegetables. Planting vegetables by raising seedlings and transplanting can prolong the growth period of crops, increase their multiple cropping index, alleviate the contradiction of insufficient accumulated temperature, and increase vegetable yield. The use of vegetable transplanting can also establish the early growth advantage of vegetables to weeds when transplanting, which is conducive to inhibiting the growth of weeds and improving the use efficiency of water and fertilizer in the field. Vegetable transplanting can also avoid the lack of seedlings caused by the low germination rate faced by...

Problems solved by technology

The hanging cup planting mechanism has the advantages of strong adaptability, high reliability, and can be transplanted on the film. However, because the movement trajectory of the hanging cup in the hanging cup planting mechanism is a trochoid, it cannot achieve zero speed in the true sense. When throwing seedlings, when the hanging cup is separated from the seedlings, the hanging cups that have not been fully opened can easily move the stems and leaves of the seedlings, affecting the uprightness of the seedlings
