Abstract

The utility model relates to a corn hill-drop planter, and pertains to the agricultural machinery technical field. The planter is characterized in that a lifting rack is provided with a wheel axle, a road wheel is arranged outside the wheel axle, a number of cone-shaped excavating shovels are provided evenly on the outer margin of the road wheel, a seeding outlet baffle plate and a tension rod are riveted with a seeding outlet of an excavating shovel, a reset spring is arranged at the hinge, a seeding wheel is provided above a seeding inlet of an excavating shovel, a seeding funnel, a seeding channel and a seed box are communicated with the top of the seeding wheel, one end of the lifting rack is hinged with a trailing bar, the other end of the lifting rack is fixed at an action bar, an arc returned soil plate is riveted at the rear part of the trailing bar, and a spring is set between the returned soil plate and the trailing bar. The utility model has the advantages that the planter is most suitable for seeding after ridges are made when the soil is still wet, preserves the soil moisture and fertilizer, does not damage ridges, ensures the uniform seeding depth, guarantees the synchronous emergence with an even row distance, and helps to increase the yield.

Description

The corn hill-drop planter

Technical field

The utility model belongs to the farm machinery technical field.

Background technology

At present, sower can be divided into two classes, and a class is the sower that use trench digging back on the land for growing field crops, and its deficiency is not preserve soil moisture, and does not protect fertilizer, hold up soil after, seed is deep mixed; Another kind is the sower that can directly sow, and its deficiency is the easily inclined to one side moisture in the soil of seed, and seed is deep mixed, causes seedling-growing time inconsistent, the underproduction easily.

Summary of the invention

The purpose of this utility model is:

A kind of soil moisture conservation is provided, protects corn hill-drop planter fertile, that sow and hold up the soil thickness unanimity.

The technical solution of the utility model is;

On crane, be fixed with wheel shaft, wheel shaft is fixed with road wheel outward, the road wheel outer rim evenly is fixed with several cone barrel clay diggers, at clay digger sow exit hinged securement sow outlet damper and pull bar, and be provided with back-moving spring in the hinged place, above the clay digger seed inlet, be provided with the rotating thumb wheel of sowing, sowing, the thumb wheel top is communicated with the funnel of sowing, sow passage and kind case, crane one end and bracket hinged securement, the other end and descending operation bar are fixed, hinged securement has the arc soil returning plate at the bracket rear portion, is provided with extension spring between soil returning plate and the bracket.

The beneficial effects of the utility model are:

This sower is suitable for sowing after the top slurry is beaten ridge most, and soil moisture conservation, guarantor's fertilizer do not destroy the field ridge, and the degree of depth of sowing unanimity has guaranteed that seedling-growing time is identical, and the spacing in the rows unanimity helps volume increase.
