How is the subsoiling machine maintained?

Standardized maintenance is a reliable guarantee for the normal operation of the deep loosening machine, which is more conducive to improving the quality of deep loosening and ground preparation, prolonging the service life of the deep loosening machine, and reducing the energy consumption during the operation.


(1) Basic maintenance. Basic maintenance refers to the maintenance and inspection before and after each operation of the subsoiling machine, mainly including technical status inspection of machines and tools, reliability inspection of parts assembly, status inspection of lubricating parts and simple cleaning. Check the fasteners and lubricate the parts before each operation, and clean the dirt on the surface of the deep loosening shovel in time after the operation to ensure good working conditions.

(2) maintenance before storage. First of all, clean the deep loosening machine to ensure that the sludge and debris are cleaned up; secondly, check the wear and damage of the main working parts, and repair or replace the damaged or missing parts in time; third, the exposed key metal parts should be coated with oil to prevent rust, and the important bearings should be added with enough grease; Choose a dry and ventilated storage place, and pad the machines and tools to prevent deformation of the shovel tip. The machine is reliably covered for long-term storage.

Problems and solutions in operation:

1. Uneven operation depth

The reasons for the uneven depth of operation are: deformation of some loose soil or irregular installation; The front end of the loosening shovel is tilted, resulting in an excessive penetration angle; The depth or horizontal adjustment of the deep loosening part is improper; The vertical adjustment of the traction frame is improper. If the working depth is not uniform, the state of the subsoiling frame, subsoiling parts and lifting mechanism should be carefully checked and adjusted. Adjust the subsoiling shovel so that the total height of the subsoiling shovel end above the tip of the shovel does not exceed 15mm. At the same time, check the horizontal state of the subsoiling machine and adjust the pull rod to make the front and rear frames and the slitting shovel meet the requirements of horizontal operation.

2. The soil is too loose after tillage

The reasons for the loose soil after ploughing include: the plough body entangles a large number of weeds or sticks to a large amount of soil, resulting in a large amount of soil disturbance; the forward speed is too fast, resulting in too fast soil cutting speed; the plough body is improperly installed and the soil stress is abnormal. If the soil is too loose after tillage, the cause of the problem should be analyzed. If there are too many weeds in the field, the weeds should be cleaned in time during operation; when the plough body is easy to clay, it should be avoided to work on too wet land as far as possible; check the levelness of the plough body to ensure that the plough body is not deflected.

3. Insufficient tillage depth

Reasons for insufficient tillage depth: poor condition of the loosening parts or lifting device, improper installation or adjustment of the loosening device, resulting in insufficient lowering depth of the machine; due to too hard soil, blunt blade of the subsoiling shovel or tangled weeds, the subsoiling shovel is difficult to penetrate the soil; Excessive soil resistance, difficult operation, etc. For the problem of insufficient tillage depth, first of all, carefully analyze the soil condition and plow bottom depth before operation to determine a reasonable deep loosening depth; secondly, check the lifting of the deep loosening device to see if it is prone to problems such as stagnant or slow lifting, and adjust hydraulic pressure and other related components in time when problems are found; according to different soil conditions, reasonably match the power of the tractor to avoid the problems of insufficient power and forced operation.

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.
