Seed arranging system of full-electrically driven seed arranging potato precision planter

Abstract

A seed arranging system of a full-electrically driven seed arranging potato precision planter comprises a seed arranging chain, a motor and a speed reducer. A plurality of seed taking spoons are evenly arranged on the seed arranging chain, a seed taking spoon position signal carrier is mounted at the same position of each seed taking spoon, a seed taking spoon position sensor is arranged on one side of the position where each seed taking spoon position signal carrier is correspondingly mounted, and the seed taking spoon position sensors are correspondingly provided with seed arranging detecting photoelectric sensor sets. The seed arranging detecting photoelectric sensor sets and the seed taking spoon position sensors are connected with a system controller, the system controller is connected with a driver, and the driver is connected with a motor. According to the full-electrically driven seed arranging potato precision planter, a seed arranging system supported by a three-detection miss-seeding and compensation decision making system formed by the seed taking spoon position signal carriers, the seed arranging detecting photoelectric sensor sets and a core computation processor CPUis provided, the overall structure of the system is fundamentally simplified, no additional standby seed arranging device is needed, power needed by the system is reduced, matched power is reduced, and investment is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and electric automation thereof, and in particular relates to a seeding system of an all-electric drive seeding potato precision seeder. Background technique [0002] With the continuous improvement of potato planting area and mechanization degree, some shortcomings of potato planting mechanization itself are gradually revealed. The main reason is that cut potatoes are planted in most areas of my country. Due to the different shapes and sizes of potato pieces, it is easy to miss seeding when picking seeds from the seed spoon during operation, which will lead to undue reduction in production. An effective measure to solve the problem of missing seeding is to increase the sowing monitoring and missing seeding compensation device, detect the lack of seeds on the seed picking spoon, and replant in time. At present, there have been relevant researches on missed-seeding monitoring at hom...

Problems solved by technology

At present, there have been relevant researches on missed-seeding monitoring at home and abroad. For example, Wang Guanping proposed "Potato missed-seeding detection and bolt-type re-seeding device electronic control system based on AVR single-chip microcomputer". Tube monitoring, and a set of spare seeding device is installed outside the original seed metering device. When the original seed metering device misses sowing, the spare device performs reseeding. This kind of seed metering device and missed sowing reseeding device are independent of each other. The structure of the method is complicated, and there is a prerequisite requirement that the potato seeds to be supplemented should be placed in advance in the limited cavity, which is prone to the problem of self-blocking of the compensation potato seeds; on this basis, the team also proposed a "one-way clutch seed supplement An integrated potato planter", the core of the idea is that the use of the one-way clutch enables normal sowing and replanting to use different power sources, but does not require a reseeding box, and the latter seed picking spoon catches up with the previous leaking seed spoon to compensate , the system is indeed relatively novel, but the switching of the power may easily lead to unstable operation of the machine, and the intervention of the compensation system power suddenly jumps from zero, which brings a relatively severe challenge to the mechanical realization of the system
