disc harrowIt is a rake group composed of multiple concave discs fixed on a horizontal axis, mainly used as a working part of the farming machine. Its main purpose is to break the soil after ploughing, so as to meet the agronomic requirements of soil preparation before sowing. It can also be used for weeding or shallow tillage on post-harvest stubble. We can also choose heavy duty when ploughing.disc harrow.
Generally useddisc harrowThe configuration forms are the following three types:
1. single row opposed type: the rake group of single row opposed type is divided into two types: left and right sides are arranged in a single row and horizontal row, and the left and right rows are respectively composed of one or more rake groups with opposite concave surfaces.
2. double-column opposed type: has two front and back columns. Each column is symmetrically configured by two rows of rake groups on the left and right. The concave surfaces of the discs of the two rows of rake groups in the front row are opposite to each other, and the discs of the two rows of rake groups in the back row are between the two discs of the rake group in the front row and opposite to the concave surface. Some people deliberately staggered the left and right rake groups in order to avoid leaving a leakage zone at the junction of the left and right rake groups of opposing rakes.
3. offset type: this form is composed of two rows of disc concave opposite rake group. Since the lateral force of the front and rear row rake groups is balanced with the traction force, the width center line of the rake can deviate far from the longitudinal axis of the tractor during operation, so it is called offset rake. When applied to an orchard, the offset rake can reach under the canopy to work. Since the offset harrow has no leakage zone, it is also widely used in field operations.
