Application characteristics of combined ground preparation machine

  The application characteristics of the combined soil preparation machine: Farming and soil preparation in agriculture are mainly the process of ploughing and crushing the soil with machines and tools. In this process, the soil structure is loose and the surface is flat, the physical properties of the plough layer are effectively optimized, and favorable conditions are created for further sowing. Traditional mechanized tillage and land preparation work can only be completed by tractor hanging plow, subsoiler or rotary tiller for many times, but due to the excessive number of agricultural machinery tools into the ground, it is easy to produce serious compaction problems on the soil, resulting in the destruction of the aggregate structure in the soil layer, affecting the yield and quality of crops. With the continuous progress of agricultural production in China, more and more high-power tractors are used for large-scale arable land production, and their supporting agricultural machinery tools have also begun to transform into composite multi-functional integration. As a supporting equipment of high-power tractors, the combined soil preparation machine can complete all the requirements of farming and soil preparation in one operation, and significantly improve the efficiency of agricultural production.

At present, there are many kinds of combined ground preparation machines used in agricultural production in China, but the overall structure principle is similar. Taking the rotary tillage combined soil preparation machine as an example, this type of machinery is mainly based on the rotary tiller, combined with stubble, deep loosening, crushing, ridging or stubble pressing and other part or all of the functions and structures. And through different combinations to form different refinement models. Such as: subsoiling rotary tillage combined soil preparation machine, stubble subsoiling rotary tillage ridging combined soil preparation machine, stubble rotary tillage ridging combined soil preparation machine, straw crushing and returning rotary tillage machine, etc. After the rotary tillage combined soil preparation machine and tractor suspension installation, it can be well applied to the ridge tillage or flat tillage combined soil preparation in the arid and semi-arid areas of agricultural production in China.

The task of the combined soil preparation machine is to create a reasonable structure, fine surface, loose and flat structure for the cultivated land at one time, and lay the foundation conditions for crop production. At present, most combined soil preparation machines combined with subsoiling function can break the traditional plough bottom, increase the depth of soil layer, effectively ensure the high-quality growth of crop roots, and improve the ability of crop resistance to lodging.

Advantages of combined soil preparation machine Compared with traditional agricultural mechanized farming and soil preparation operations, combined soil preparation machine has the following technical advantages: work efficiency is significantly improved. The use of composite functional structure avoids the waste of time in multi-step operations, shortens the average tillage and preparation time by 8-10 days, effectively increases the crop growth cycle, and improves the annual effective accumulated temperature. The second is to effectively achieve water storage and moisture preservation. With the reduction of the number of agricultural machinery into the ground, the soil compaction is obviously alleviated, the aggregate structure of topsoil is preserved, the effective depth of topsoil is obviously increased, the problem of soil erosion is alleviated, and it is easier to build high-quality underground reservoirs. The third is to significantly reduce energy consumption and environmental pollution. Compared with the traditional multi-tillage mode, the joint soil preparation operation can save about 15kg of oil per hectare on average, and save 30% ~ 40% of oil. Moreover, due to the small number of operations and short time, it can effectively control exhaust emissions and help reduce environmental pollution.

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.
