What are the precautions in the use of the combined land preparation machine?


The blade shaft of the combined soil preparation machine is driven by the power output shaft of the tractor to rotate and move to crush the wasteland or cultivated land.

Precautions for 1. use


(1) In order to prevent leakage and blockage of the combined ground preparation machine during the working process, so that the shaft of the combined ground preparation machine is evenly stressed, the knife seat is staggered and welded with the knife shaft according to a certain rule. Therefore, when installing the left and right scimitars, you should proceed in sequence and pay attention to the rotation direction of the knife shaft to avoid installation errors or reverse installation. After the blade is installed, it should be checked. According to the needs of operation, the installation methods of left and right machetes are as follows: ① outward installation method: the tips of both ends of the blades are inward, and the other blades are outward. ② inward installation method: all the tips of the blades are symmetrical inward, and the middle of the ground surface is raised after plowing, which is suitable for field farming with grooves. ③ Mixed assembly method: the tips of both ends of the blade are inward, and the other tips are staggered inside and outside. This installation method is relatively flat after ploughing.


(2) When the combined ground preparation machine is working, the power supply should be connected in the lifting state. After the combined ground preparation machine reaches the predetermined speed, the tractor can be started, and the combined ground preparation machine slowly descends to make the combined ground preparation machine in the soil. It is strictly forbidden to start the combined ground preparation machine directly in the soil to avoid damage to the combined ground preparation machine and related components. It is strictly forbidden to drop the combined ground preparation machine quickly.


(3) During the operation of the combined ground preparation machine, the height difference between the horizontal axis of the output and input shafts at both ends should be minimized, and the deflection angle of the drive shaft should not be greater than 10 °. Cut off the power when crossing a ridge or plot. During operation, adjust the length of the left and right diagonal tie rods to make the cutter shaft of the combined ground preparation machine parallel to the ground to ensure the same plowing depth on the left and right sides. The ideal forward speed of the combined ground preparation machine is 2~3 km/h, and the blade shaft speed of the combined ground preparation machine is 210~300 r/min.


(4) During rotary tillage operations, the tractor can only drive in a straight line and cannot turn or reverse. When the ground is turning and the power supply is not cut off, the combined ground preparation machine should not be lifted too high, and the engine speed should be reduced appropriately to avoid damage to the universal joint. The drive angle at both ends of the universal joint should not exceed 30 °. When transferring fields or walking for a long distance, cut off the power supply of the combined ground preparation machine, lift the combined ground preparation machine to the .. position and lock it.


(5) When installing the universal joint, the end with the square shaft is installed on the combined floor preparation machine, and the end with the square sleeve is installed on the output shaft of the tractor. Cross the inner and outer sides of the joint to keep the two inner yokes and the two outer yokes on the same horizontal line. If the installation direction is wrong, it is easy to produce vibration and cause damage to the parts. The gearbox should be filled with the specified amount of gear oil. The bearings at both ends of the drive shaft should be filled with yellow grease.


2. Adjustment method


(1) Adjust the plowing depth. For the combined soil preparation machine equipped with wheeled tractors, the tillage depth is generally controlled by the tractor hydraulic system through position adjustment, or the depth-limiting sliding plate is installed on the combined soil preparation machine; adjustment.


(2) Level adjustment. For the three-point suspension combined floor preparation machine, the left and right levels are adjusted with the right lifting rod of the tractor, and the front and rear are adjusted with the upper rod of the tractor.


(3) Adjustment of lifting height. The lifting height of the cultivator in the transmission state is limited by the steering knuckle angle and does not exceed 30 °. In general, the blade should be 20cm from the ground. Before starting plowing, the hydraulic lever should be limited to the allowable lifting height.


(4) Adjust the soil crushing capacity. The earth-breaking capacity of the cultivator is related to the forward speed of the unit and the speed of the knife shaft. When the knife shaft speed is constant, the agglomeration increases when accelerating, and the agglomeration becomes smaller when decelerating.

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.
