Small disc harrow business machine structure

Since the 1940 s, cross-rolled steel plates have been used to manufacture rake tooth blades in the United States.Small disc harrowThe central hole is usually a square hole, separated by an intermediate tube. The rake and the intermediate pipe are sleeved on the square shaft and locked with nuts to form a rake group. When working,Small disc harrowThe plane of the cutting edge is perpendicular to the ground and at an angle to the direction of advance. Each rake set is supported by bearings on the frame. During operation, under the action of tractor traction and soil reaction force, each rake blade in the rake group rolls with a square axis.


Under the action of the gravity of the harrow itself, the blade of the blade cuts into the soil, cuts off the grass roots or crop residues, and cuts off the strips after tillage, so that the soil rises slightly along the concave surface of the blade, and then falls down, which has a certain soil covering effect. The deflection angle of the small disc harrow group can be adjusted, the adjustment range is generally 0 ° ~ 30 °, and the commonly used deflection angle is 10 ° ~ 25 °. Increasing the deflection angle will increase the depth of the blade of the small disc harrow, and increase the effect of rotating and crushing the soil, and the resistance will also increase.


Hanging disc harrow manufacturers, agricultural mower suppliersTo tell you, the small disc harrow is composed of a harrow frame, a harrow group, a traction or suspension device, and a deflection adjustment mechanism. In order to increase the depth of the soil, some light and small rakes are equipped with counterweight boxes on the rake frame. The small disc harrows produced and used in the 1980 s distributed a relatively large weight on each disc and had sufficient soil penetration capacity, so there was no need to add weights and adjust the deflection angle. When installing the rake group, the deflection angle of the rake group should be fixed at the best position. When shallow tillage is required, wheels controlled by hydraulic cylinders limit the depth.


TractionSmall disc harrowThe rake is usually equipped with equipment that can automatically adjust the transportation status and manually fine-tune the working status on the traction device. With the help of the lifting of the wheels and connecting rods, the rake remains level at all times. Drive disc harrow price, deep loosening machine price is also very popular.

The correct use and maintenance of the disc harrow: in operation, the technical condition of the rake, scraper, square shaft, bearing, angle adjuster and connecting parts should be checked frequently, especially the end nut of the disc harrow group and the fixing bolts of each bearing. If it is found loose, tighten it in time, and remove the weeds and dirt on the workpiece in time.

How to maintain planter accessories

Planter A planting machine using crop seeds as a planting object. Planters for a certain type or crop are usually named after the crop type, such as wheat planter, cotton planter, etc. Planter accessories are very effective in farmland operations, so the planter accessories are easily damaged. Next, the planter manufacturer will introduce how to maintain the planter accessories. Before using the planter, we should have a simple and comprehensive understanding of the principles of all planter accessories. The planter manufacturer stated that it can be effective as long as the maintenance is carried out on the correct accessories to ensure the normal use of the planter accessories. The planter will extend its life.

Defects in castings and forgings

The defects produced in the casting and forging process are similar to the defects produced in the ingot, but they are still process defects, including pores, inclusions, shrinkage holes, loose holes, cracks, etc.

Production of castings and forgings

Castings and forgings must be melted by electric furnaces, mainly electric arc furnaces and induction furnaces. According to the different lining materials and slag system, can be divided into acidic furnace and alkaline furnace. Carbon steel and low alloy steel can be smelted in any furnace, but high alloy steel can only be smelted in alkaline furnaces.

Inspection of Casting and Forging

The complex information system management interface of casting and forging, such as poor ultrasonic penetration, coarse grain, uneven organization, etc., all enhance the scattering of an ultrasonic wave by students, and the energy can be effectively attenuated, so that the detectable thickness is smaller than that of forgings.

What are the advantages and disadvantages of casting and forging

One of the advantages of casting and forging is the flexibility of design. Personnel design has a large degree of freedom of design choice for the shape and size of castings, especially for parts with complex shapes and hollow sections. Steel castings can be manufactured using a unique process known as core assembly.
