Tractor disc harrow: the whole structure of disc harrow, small disc harrow


disc harrowRake group configuration form:
The commonly used disc harrow has the following configuration forms:
The left and right sides of the single row of opposing rake assemblies are arranged in a single horizontal row, and the left and right rows are respectively composed of one or more rake groups with relatively concave surfaces. Shallow tillage for the levelling of irrigated land, post-harvest stubble and fallow land.

There are two lines before and after the two lines. Each column is symmetrically arranged by two rows of rake groups. The concave surfaces of the discs of the first two rows of rake groups are opposite; the discs of the second two rows of rake groups are located between the two discs of the front row of rake groups and are opposite to their concave surfaces. To avoid missing tillage bands remaining at the junction of the left and right sets of opposing rakes, some of the opposing sets of rakes are staggered.
The offset type consists of groups of concave opposing rakes of the front and rear disks. Since the lateral force and traction force of the front and rear rake groups are balanced, the center line of the rake width will deviate far from the longitudinal axis of the tractor during operation, so it is called partial rake. The offset of the wide offset rake can reach more than 3 meters. When used in an orchard, the offset harrow can be extended to work under the canopy where tractors cannot enter; the offset harrow is also widely used in field operations because it has no leakage zone.

disc harrowThe whole machine structure
tractor disc harrowIt is composed of rake frame, rake group, traction or suspension device, deflection angle adjustment mechanism, etc. In order to increase the buried depth, someSmall disc harrowA counterweight box is installed on the rake frame. Disc harrows produced and used in the 1980 s have a large weight distributed on each disc, so there is no need to increase the weight and adjust the deflection angle. When installing the rake group, the deflection angle is fixed in the best position. When shallow tillage is required, the depth is limited by wheels controlled by hydraulic cylinders.
tractor disc harrowIt is usually equipped with a device that automatically adjusts the transportation state and manually adjusts the working state of the traction device. With the help of lifting wheels and connecting rods, the rake remains level at all times.

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.
