What are the benefits of agricultural deep loosening machine for land preparation?

For a long time, due to the influence of traditional agricultural farming methods and the limitations of agricultural machinery, farmers are accustomed to using small tractors for rotary tillage or shallow turning, resulting in shallow tillage, soil hardening, and poor water retention, drought resistance, and waterlogging prevention capabilities. Agricultural machinery subsoiling technology refers to the use of different power machinery in the field to complete the subsoiling machine operation mechanization technology.


The purpose of subsoiling is to loosen the soil, break the bottom of the plow, deepen the tillage layer without turning the soil, improve the soil structure of the tillage layer, increase the speed and amount of rainwater infiltration, reduce the loss of runoff and water evaporation, and improve soil water storage and drought resistance And fertilizer retention capacity. Suitable for dryland agricultural mechanization production. Vigorously carrying out deep loosening machine land preparation is a powerful measure to promote the steady growth of grain output and improve the comprehensive agricultural production capacity. It is also an effective way to improve the utilization rate of resources, improve the quality of cultivated land, improve the ecological environment and promote the sustainable development of agriculture.

The benefits of deep loosening machine operation are as follows:

1. Break the bottom of the plough. Rotary tillage and shallow tillage of the soil for many years will form a hard plow bottom, which will hinder the penetration of rain and the planting of crop roots. When subsoiling, the subsoiling shovel passes through the lower part of the plow bottom, which can effectively break the original plow bottom and deepen the plow layer. Mechanical deep loosening can reach a depth of 30-50cm, which is a depth that cannot be reached by other farming methods.

2. Improve soil water storage capacity. The subsoiler broke the bottom of the original hard plow. At the same time, the deep loose part of the soil is loose, which is conducive to the penetration of rain and snow. In addition, the increase of general soil surface roughness after subsoiling will hinder rainwater runoff and prolong the benefit of rainwater infiltration subsoiling.

3. Improve soil structure. Subsoiling machine will form the soil structure of lack of fertilizer and fertilizer, which is conducive to the gas exchange of soil, promote the activation of aerobic microorganisms and the decomposition of minerals, increase the solubility of chemical fertilizer, reduce the volatilization and loss of chemical fertilizer, so as to improve the utilization rate of fertilizer, so as to promote the cultivation of fertility.

4. Eliminate soil compaction caused by machine entry. Some necessary mechanical operations from crop planting to harvest, such as sowing, spraying and harvesting, will cause some soil compaction. The subsoiling operation can clean up the soil compaction caused by the machine entering the operation.

5, is conducive to crop growth. After deep loosening, the soil becomes loose, promoting crop root development and improving lodging resistance. After subsoiling, the soil bulk density is 12-13kg/cm3, which is suitable for crop growth and development, and the yield per mu is increased by more than 5%.

The technical requirements of the subsoiling machine are as follows:

1. Subsoiler operation time. Conditions for storing more moisture after deep loosening are relatively more rainfall and snowfall. Considering the regional characteristics of our province, the subsoiling operation in the eastern agricultural area should generally be arranged before the rainy and snowy season, that is, after the harvest in summer and autumn, before freezing; however, the soil in the farming-pastoral ecotone has been frozen after the harvest in autumn, so it is suitable for deep soil loosening in spring.

2. The deep loosening depth of the deep loosening machine. The criterion for determining the depth of subsoiling is to break at 5-10cm below the bottom plow, and the depth reaches 25-30cm.

3. Deep loosening spacing. The soil loosening range of the single-column subsoiling machine is based on the tip of the shovel, and the soil is loosened at 45 degrees upward on both sides. With the different depth of subsoiling, a single subsoiling shovel on the surface of the different width of the pine. When the deep loosening depth is 25cm, 30cm and 35cm, the loosening width of topsoil is 50cm, 60cm and 70cm respectively.

4. Soil moisture requirements for subsoiler operation. Subsoiling operation has strict requirements on soil moisture content. Soil water content is too large or too small, subsoiling operation quality is poor, such as large subsoiling ditch, large soil block, etc., in addition to the operation resistance is also large.

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.
