Disc plow shake his head difficult, what's going on?


disc ploughDuring operation, the soil acts ondisc ploughWhen the deflection torque generated by the force of the tractor is less than the torque generated by the lateral reaction force of the soil borne by the front wheels of the tractor, the unit can drive in a straight line; otherwise, the tractor will automatically tilt its head to one side, causing difficulty in steering.disc ploughThe unit automatically swings its head during operation, making it difficult to steer, indicating that there is a deflection moment in the unit, which is called partial traction. Try to eliminate or reduce the deflection moment, you can eliminate or improve the phenomenon of partial traction. Efforts should be made to reduce the unbalanced force of the soil acting on the plough, or to reduce the distance from the unbalanced force to the power swing center. The force of the soil acting on the plow body can be decomposed into lateral force and longitudinal force according to the effect of the action.

disc ploughIn the design, the tail wheel is specially set to balance the force of the soil on the plough body to maintain the straight line of the unit. If the tail wheel deformation damage, or improper adjustment will not play a balance.disc ploughThe deformation of the body, plough frame, plough column, etc. will also cause the soil to increase the force on the disc plough body, destroy the original adjustment of the plough body state, resulting in partial traction phenomenon.

How to troubleshoot?

① First check whether the disc plow body, plow frame, plow column, tail wheel, etc. are deformed or damaged, and if so, repair them according to the above methods. ② Then carry out trial tillage. If there are still problems, adjust them according to the following steps, and try while adjusting until the problem is solved. Step 1: Adjust the direction and height of the tail wheel to balance the force of the soil on the disc plough body and reduce the unbalanced force. Step 2: Adjust the relative position of the two lower suspension points of the suspension shaft frame and the plow frame, and also reduce the deflection moment. Note that this adjustment should be considered in conjunction with the tillage width adjustment. Step 3: Adjust the position of the upper pull rod. Generally, the upper pull rod is parallel to the forward direction of the unit or slightly skewed to the left to improve the partial traction phenomenon.

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.
