Driving-resistance self-regulated furrow opener assembly suitable for wheat medium-term deep fertilizing machine

Abstract

A disclosed driving-resistance self-regulated furrow opener assembly suitable for a wheat medium-term deep fertilizing machine comprises a first sensor, a single-chip microcomputer control system, a storage battery, a driving motor, a furrow opener, an auger, a clutch lever, a second sensor, belt pulleys, a soil resistance test rod, a belt and meshed bevel gears; the storage battery and the driving motor are installed at the front end of a rack; the soil resistance test rod is installed at the left of the front end of the rack; the second sensor is installed between square steel and the soil resistance test rod; the clutch lever is installed below a fertilizer box; the clutch lever is provided with three pairs of the meshed bevel gears and the belt pulleys; the auger is installed below the clutch lever; and a furrow opener is installed at the rear end of the rack. The furrow opener assembly provided by the invention is free of pollution and small in noise; when soil hardening is severe, the resistance of the furrow opener during working is reduced, the damage to the furrow opener is reduced and the service life of the furrow opener is prolonged; and also the intelligent automatic regulating on the driving resistance is realized, proper torque is output by controlling the driving motor, excessively-large or excessively-small torque is avoided to output, and the furrow opener assembly is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and tools, in particular to a ditch opener assembly suitable for self-adjusting driving resistance of a deep fertilizing machine in the middle stage of wheat. Background technique [0002] The period from jointing to booting of wheat is the maximum efficiency period of nitrogen fertilizer. Therefore, 30% of the nitrogen test amount of wheat should be moved to topdressing at jointing stage, which is commonly known as winter fertilization. However, at the present stage in our country, the popularity of wheat fertilization in winter is not high. Many farmers do not fertilize or adopt the method of spreading fertilization. The fertilizer effect cannot achieve the expected effect, and it is difficult to achieve high yield of wheat. The reason is that the soil hardens severely in winter. If chemical fertilizers are applied, they can only be carried out in rainy days. Therefore, most farme...

However, at this stage in our country, the popularity of winter wheat fertilization is not high, and many farmers do not apply or adopt the method of spreading fertilizer, the fertilizer effect cannot reach the expected effect, and it is difficult to achieve high yield of wheat

The reason is that the soil hardens severely in winter. If chemical fertilizers are applied, they can only be carried out in rainy days. Therefore, most farmers choose not to apply them, and it is difficult to increase the yield of wheat.
