A Distributed Feeding Potato Seed Metering Device

Abstract

A distributed feeding potato seeding device, comprising: a frame; a test seed box installed on the frame; a lifting auger mechanism installed on the frame and located under the test seed box , the outlet of the test seed box is connected to the feeding port of the lifting auger mechanism for controlling the feeding amount of seed potatoes; the spoon type seeding mechanism is installed on the frame and is located in the lifting Behind the auger mechanism, the outlet of the lifting auger mechanism is set corresponding to the entrance of the scoop-type seed metering mechanism, which is used for single seed separation, filling and seeding of seed potatoes; the transmission device is installed on the on the frame, and respectively connected with the lifting auger mechanism and the scoop type seeding mechanism; and the control device, installed on the frame, the control device is connected with the transmission device, and adjusts the The operating speed of the transmission. The invention fundamentally solves the problems of high seed leakage rate and low efficiency of the spoon-type potato planter.

Description

technical field [0001] The invention relates to an agricultural seeding device, in particular to a distributed feeding type potato seed metering device. Background technique [0002] Potato is the fourth largest food crop, with high and stable yield, and is rich in nutrients. In recent years, my country's planting area and total output have ranked first in the world, accounting for about 1 / 4. According to statistics, the potato planting area in 2018 was about 72 million mu, but the machine-seeding rate was only 23%, far below the machine-seeding level of the three major staple crops. [0003] At present, the field sowing operation of potatoes is mainly manual operation. The spacing between rows and plants after sowing is not standardized, the efficiency is low, and the labor intensity is high, which 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....

AI Technical Summary

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
