The working principle of the subsoiler, disc harrow-disc plough

In order to promote the rapid development of facility agriculture, we must first develop suitable facility agricultural machinery. At present, dryland farming in orchards, greenhouses, hilly and mountainous areas has a small degree of mechanization, a large height difference, and no farming roads. Most operations rely on traditional manual labor, which is intensive and inefficient. Soil loosening operation is the basic operation. In view of the large size, poor adaptability and high price of the existing dryland farming machinery in China, a small scale suitable for the above-mentioned household terrain has been developeddeep loosening machine.





Smalldeep loosening machineCan be widely used in field farming, plastic greenhouses, tobacco, nursery, orchard, tea garden loose soil operation. The deep loosening machine has the characteristics of light weight, small size, simple structure, convenient operation, convenient maintenance, low fuel consumption and high production efficiency.
In order to promote the popularization of this machine, the structure of the deep loosening machine has been simplified. The whole machine is mainly composed of 2.5HP single-cylinder two-stroke gasoline engine, friction clutch, worm gear reducer, rotary tiller and other institutions. The deep loosening engine provides power and is connected to the drive shaft through a friction clutch. The drive shaft transmits power to the cutter shaft to drive the cutter head for farming through the worm gear reducer. In addition, the engine only provides the power to loosen the soil, while the walking and steering of the frame itself are manually controlled.






In order to reduce the quality of the whole machine, reduce the overall size, and reduce the cost, the subsooner uses a threaded connection instead of the coupling connection between the drive shaft and the worm under the premise of meeting the use requirements. The structure of the worm gear reducer has also been simplified, eliminating the need for a fuel tank and fan.
Now the agricultural aspect is becoming more and more important, and agricultural tools are becoming more and more diversified,disc harrowThe disc plow has slowly entered people's lives.

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.
