Three Configuration Forms of Disc Harrow


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.
disc harrowThe whole machine mechanism:disc harrowIt is composed of a rake frame, a rake group, a suspension device, and an angle adjustment mechanism. In the light, small rake on the rake frame device weight box, this can increase the disc harrow into the soil depth.

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.
