Distributed feeding type potato seed metering device

Abstract

The invention discloses a distributed feeding type potato seed metering device. The device comprises a rack, a test seed box, a lifting conveying auger mechanism, a spoon type seed metering mechanism,a transmission device and a control device. The test seed box is mounted on the rack; the lifting conveying auger mechanism is installed on the rack and located below the test seed box, and an outletof the test seed box is connected with a feeding port of the lifting conveying auger mechanism and used for controlling the feeding amount of seed potatoes; the spoon type seed metering mechanism ismounted on the rack and located behind the lifting conveying auger mechanism, and an outlet of the lifting conveying auger mechanism corresponds to an inlet of the spoon type seed metering mechanism and is used for single-grain separation, seed filling and seed metering of seed potatoes; the transmission device is arranged on the rack and is respectively connected with the lifting conveying augermechanism and the spoon type seed metering mechanism; and the control device is installed on the rack, connected with the transmission device and used for adjusting the working speed of the transmission device in real time. According to the device, the problems of high seed leakage rate, low efficiency and the like of a spoon-type potato seeder are fundamentally solved.

Description

technical field [0001] The invention relates to an agricultural seeding device, in particular to a distributed feeding type potato seeding device. Background technique [0002] Potato is the fourth largest food crop, with high and stable yield and rich nutrition. In recent years, my country's planting area and total output have ranked first in the world, accounting for about 1 / 4 of both. According to statistics, in 2018, the potato planting area was about 72 million mu, but the machine sowing rate was only 23%, which was far lower than the machine sowing level of the three major staple crops. [0003] At present, the field sowing of potatoes is mainly done by hand. The spacing between rows and plants after sowing is not standardized, the efficiency is low, and the labor intensity is high. It is easy to delay the farming time and cannot meet the needs of the rapid development of the potato industry. Domestic potato planters are in the stage of mechanized development. There a...

Problems solved by technology

[0003] At present, the field sowing of potatoes is mainly done by hand. The spacing between rows and plants after sowing is not standardized, the efficiency is low, and the labor intensity is high. It is easy to delay the farming time and cannot meet the needs of the rapid development of the potato industry. Domestic potato planters are in the stage of mechanized development. There are mainly problems such as high seed leakage rate and low efficiency

At present, the most widely used chain spoon seed metering device has the advantages of high reliability, low cost, and adjustable spacing. Problems such as poor sowing uniformity

In order to improve the performance of the chain spoon potato planter, some achievements have been made in the prior art by optimizing the seeding speed, the number of seeds in the seed box, and adding a vibration device. However, due to the blindness of the spoon-type seed picking method, The method of subjectively selecting several factors for parameter optimization fails to fundamentally solve the problems of missing seeding and poor seeding uniformity
