The Difference Between Disc Harrow and Disc Plough

Disc Harrow has absorbed the advantages of foreign advanced products of the same kind. According to standard design, the whole machine adopts combined structure, with Integral Rigid Harrow frame as the main body It is equipped with sealed rolling bearing with outer spherical surface and inner square hole for hydraulic lifting and transporting rubber wheel, spring leveling mechanism and disc Harrow Disc Harrow has the advantages of reasonable structure, strong and durable, convenient transportation, small turning radius, easy adjustment, maintenance and so on. Disc Harrow Plate is the main core components of disc Harrow, a disc harrow an important factor in the level of consolidation, the following we have a specific look at it:
1. Uneven hardness. During the deposition, the uneven thickness of the disk harrow by ten layers may cause the uneven hardness. The areas where the coating is hardened are usually caused by decarburization, where the operator penetrates the oxyacetylene flame center into the melted coating or where the inner flame center is 13:1 longer. The area of lower hardness of the deposited layer is usually the result of ten base metals mixed into the deposited layer.

2. Crack. The preheating temperature before the deposition is low, the process of the deposition is poorly controlled (the temperature drops too quickly) and the deposit is cooled rapidly after the deposition. Are Prone to crack in the deposited layer. Therefore, preheating and post-cooling before cladding is an important feature of ni-base cemented carbide oxyacetylene flame cladding. In addition, the Disk Harrow Operation Diagram, in the non-annealed parts of the quenching deposited also prone to cracks. If the cracks in the deposited layer have been extended to the base metal, they need to be completely removed with a grinding wheel (or by other mechanical processes) . Then according to the provisions of the process preheating, melting, slow cooling. If the crack does not extend to the base metal, the part can be reheated and melted to eliminate the crack.

The disk plow is specially designed for use on tractors The disk plow is a kind of hanging agricultural machinery, which is specially used on tractors. It is an upgraded moldboard plow. During the operation, the plough blades rotate and are used to break up soil blocks, till and stubble. It can cut off roots and stems of crops and break up bricks in the soil layer Especially useful for weedy wasteland reclamation. The Disk Plough has the advantages of non-entrapment of grass, non-blocking and non-choking soil, and can cut off the stems of crops, overcome the debris of bricks and stones in the soil, and has high working efficiency. The disk plow comprises a left arm shell, a left arm, a gear box, a transmission gear, a meshing sleeve, a joystick, a chain wheel box, a disc shaft and a DISC PLATE The utility model also comprises a left box body, a driving shaft, a right box body, a driven shaft, a driving bevel gear and a passive bevel gear, wherein the driving gear is sheathed...

Three methods to improve the efficiency of Furrow Plough

The Furrow Plough is usually used to turn over the soil in the cultivated land. The Furrow Plough is connected by a tractor to move back and forth. There are three common tillage methods of  Furrow Plough: Turning inside out method, turning outside method and turning inside out method Inversion method, also known as closed Ridge tillage. First enter from the left side of the Middle Line of the cultivated area, plow the first plow (starting moisture) , till the head of the field, then turn the plow to the right (clockwise direction) , plow the second plow along the Middle Line of the cultivated area on the right side, and then plow from the inside to the outside in order until the last plow is finished at the edge of the field. The Ridge will be formed at the midline of this tillage method. Eversion method, also known as Ridge cultivation method. First Plow to the head, then turn the plow to the left (anticlockwise direction) , return to the second plow along the left side of t...
