Deep root crop soil preparation machine

A technology of rhizome crops and soil preparation machines, which is applied to the field of deep root crops and crops with deep roots. It can solve the problems of not achieving the effect of soil preparation, the inability to dig out the roots, and large operating resistance, so as to achieve ideal soil preparation effects and crush the soil. Good effect, easy to crush the soil

Problems solved by technology

These two forms of combined subsoiler and rotary tiller are all simply combined with the subsoiler and the rotary tiller. It is only suitable for crops with shallow rhizomes. For crops with deep rhizomes, it is impossible to dig out their rhizomes and deeply break the soil, and the ideal soil preparation effect cannot be achieved.

Abstract

The invention provides a deep-rooted crop soil preparation machine and belongs to the technical field of farm machinery. The deep-rooted crop soil preparation machine comprises a rack, a transmission mechanism, at least one set of a soil preparation device and a subsoiler, wherein the soil preparation device which is oblique to the ground is mounted at the rear operation end of the rack; the subsoiler is mounted at the front operation end of the rack; the soil preparation device and the subsoiler are located on the same horizontal line; a ditching shaft of the subsoiler is connected with one end of the transmission mechanism by a driving box on the ditching shaft and the other end of the transmission mechanism is connected with a traction machine. A machine tool composed of the soil preparation device and the subsoiler is matched to operate to reach deep-rooted crop soil preparation. The upper part of the soil preparation device is provided with a ditching cutter assembly and the lower part of the soil preparation device is provided with a diameter-changing spiral packing auger; a drill bit is arranged at an operation tail end and is easily buried in soil. The ditching cutter assembly is composed of a plurality of bent blades which are spirally arrayed; the rotary tracks of the bent blades are overlapped so as to guarantee that an omission phenomenon does not occur when the blades are used for crushing the soil. A ditching shaft buttress beam on the ditching shaft can guarantee that the upper and lower parts are coaxial and the deformation amount is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a soil preparation machine for deep-root crops, which is suitable for crops with deep roots such as burdock. Background technique [0002] Existing soil preparation machines are generally subsoiling rotary tillage combined soil preparation machines, and its structure is divided into two types, one is that the front is a subsoiler and the back is a rotary tiller; the other is that the front is a rotary tiller and the back is a deep loose machine. These two forms of combined subsoiler and rotary tiller are all simply combined with the subsoiler and the rotary tiller. The characteristic is that it is only suitable for crops with shallow rhizomes. For crops with deep rhizomes, it is impossible to dig out their rhizomes and deeply break the soil, and the ideal soil preparation effect cannot be achieved. Contents of the invention [0003] In view of the a...
