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...

What to pay attention to when buying a CORN PLANTER？

1) in the purchase of Corn Seeder, to buy a formal enterprise production of famous and excellent products. Advanced performance, reliable quality. Should also have a certain scale of sales to buy merchants, good reputation, service is guaranteed. Note the random “two certificates, one card, one book (promotion license, product qualification certificate, product nameplate, use manual) , ” these documents can explain whether the product is a formal product of a support, but also to guide farmers to use the product correctly and reasonably. (2) according to the specifications or sign requirements, choose and the existing power matching and hanging the same way as the planter. (3) the adaptability of machines and tools should be considered. China’s vast territory, the situation varies widely, the northeast is Ridge Sowing; north China twice a year, after the wheat harvest to no-till. The choice of machinery must therefore be based on local farming practices and technical requirements....
