Embodiment Construction

[0011] In the figure, the speed of the power output shaft of the tractor is 1000rpm, and it is connected with the input shaft of the main gearbox (5) through a universal joint. The other power output of the gearbox (5) is transmitted to the auxiliary gearbox (6) through the universal joint, the transmission ratio is 2:1, and the rotating speed of the stubble cutter is 500rpm; the ditch opener (11) is an adjustable seed fertilizer layer thickness The composite opener adopts a single-row structure, and its entry angle is 120°. The opener (11) is connected to the girder through the consolidation device (16). The sowing depth can be changed by changing the upper and lower positions of the opener (11) on the consolidation device (16); the pressing wheel (9) is of the integral floating adjustable pressure type, and the pressing force can be changed by changing the initial compression amount of the pressing wheel spring , the suppressing wheel (9) doubles as the ground wheel, and the...

Abstract

The invention relates to an adjustable suppression sowing machine used for burying fertilizers through twin axle type stubble-cleaning rotary tillage of stub land operation, and comprises a fertilizer can, a seed box, a fertilizer feeder, a fertilizer-feeding chain wheel, a suspension frame, a large beam, a main gear box, a supplementary gear box, a stubble-cleaning cutter, a rotary-tilling cutter, a planker, a suppressing wheel, a suppressing wheel chain wheel, a suppressing wheel support, a cross-bridge chain wheel, a seed-feeding chain and a fertilizer-feeding chain wheel and the like; the sowing machine adopts a composite oblique-angle furrow opener which can adjust the thickness of the layered seed and fertilizer, and the furrow opener is distributed in a single row with the distance of step-less regulation of 20 to 25cm; the suppressing wheel is whole floating pressure adjustable type; the suppression force is changed by changing the initial compression of the suppressing wheel which is also used as a ground wheel; the cross-bridge chain wheel is arranged on a support shaft of the suppressing wheel; and when the suppressing wheel floats up and down, the tension of the upper chain is not changed. The sowing machine can complete the operations of stubble cleaning, rotary tillage, fertilizer burying, sowing and suppression and the like simultaneously by entering into the field one time.

Description

Technical field [0001] The invention relates to a double-shaft stubble removal rotary tillage fertilizer deep application adjustable suppression pressure seeder for improving the yield of wheat, which can simultaneously complete stubble removal rotary tillage, fertilizer deep application, wide row sowing, overall suppression and other operations in one operation; especially It is a wheat rotary tillage planter with adjustable layer thickness of seed fertilizer and adjustable pressure. Background technique [0002] At present, the known rotary seeder adopts the method of rotating fertilizer into the soil while sowing, which reduces the utilization rate of fertilizer, increases the amount of fertilizer, increases the operating cost, and is not conducive to environmental protection; On the one hand, the current soil preparation part of the rotary seeder is a rotary tiller. Since the rotation speed of the rotary tiller is about 250rpm, the quality of sowing the plowed land is be...
