Vibration circular disc type no-tillage anti-blocking device

Abstract

The invention belongs to the technical field of agricultural machinery and relates to a vibration circular disc type no-tillage anti-blocking device The vibration circular disc type no-tillage anti-blocking device consists of a machine frame, an anti-blocking device and a gearbox, wherein the anti-blocking device comprises four anti-blocking units and each anti-blocking unit comprises a crank rocker rod mechanism consisting of an eccentric rolling tube, a first bearing, a rocker rod and a swinging rod, eccentric rolling tubes arranged in each anti-blocking unit are driven to rotate by the rotation of an output shaft of the gearbox and anti-blocking driving shafts, the eccentric rolling tubes drive the first bearing to do eccentric movement, the first bearing drives the rocker rods to do upward and downward reciprocating movement, the rocker rods drive the swinging rods to do upward and downward swinging, and the swinging rods drive a circular disc connecting frame and a stubble cutting circular disc cutter to do upward and downward vibration, so in the forward moving process of the vibration circular disc type no-tillage anti-blocking device, the stubble cutting circular disc cutter forwards rolls for cutting straws and exerts the upward and downward vibration, and the vibration stubble cutting anti-blocking effect is realized. The vibration circular disc type no-tillage anti-blocking device combines the characteristics of small soil disturbance and low power consumption of a passive anti-blocking device and the characteristic of high anti-blocking capability of a driving type anti-blocking device, the universality is high, and the vibration circular disc type no-tillage anti-blocking device becomes a wheat and corn no-tillage seeding machine after the installation of a ditching device, a compression mechanism and a seed and fertilizer box.

Description

technical field

[0001] The invention belongs to the technical field of agricultural machinery, in particular to a vibrating disc type no-tillage anti-blocking device. Background technique

[0002] After decades of practical research in my country, it has been shown that conservation tillage technology can use crop stalks to cover the surface and avoid less tillage, reduce soil wind erosion and water erosion, and improve soil fertility and drought resistance. At present, the blockage of no-tillage planters caused by large straw coverage is the difficulty and focus of conservation tillage technology. It is of great significance to design and develop an anti-blocking device for planters suitable for my country's conservation tillage technology. At present, there are mainly two types of anti-blocking devices for no-tillage seeders in my country: passive anti-blocking devices and power-driven anti-blocking devices.
