Combined land preparation machine used in traditional agriculture

The combined soil preparation machine is used in traditional agriculture. With the rapid development of agricultural technology in China, the requirements of agricultural production on cultivated land technology, cultivated land quality and cultivated land machinery are becoming more and more strict. It is not only required that the entire arable land can meet the growth needs of crops, but also solve a series of problems such as soil erosion and soil fertility decline caused by arable land, as well as energy consumption and environmental protection issues. Traditional farming methods and techniques can no longer meet the above requirements, and conservation tillage is an effective way to solve this problem. The combined soil preparation machine used in conservation tillage technology can complete deep loosening, rotary tillage, stubble cleaning, ridging and other operations at one time, effectively ensuring that the physical and mechanical properties of the soil itself will not be excessively damaged, while reducing fuel consumption and promoting crop growth Increase production has been widely recognized by farmers.

The combined soil preparation machine is a multifunctional soil preparation machine, which is composed of engine, frame, traction frame, middle beam, transmission box, subsoiling shovel assembly, stubble removal assembly and rotary tillage assembly. The transmission box is arranged on one side of the frame, 7 meshing gears are arranged in the transmission box, and a middle beam is arranged in parallel between the rotary tillage shaft and the stubble extinguishing shaft. The combined ground preparation machine is a multi-functional ground preparation machine. Frame, traction frame, center beam, transmission box, subsoiling shovel assembly, stubble removal assembly and rotary tillage assembly. The gearbox is installed on one side of the frame. It is equipped with 7 meshing gears. The middle beam is parallel to the rotary tillage axis and the stubble axis. The deep loosening shovel assembly is installed on the cross beam, and the rotary tillage shaft is directly driven by the output shaft of the gearbox. The universal joint is connected with the input shaft of the gearbox, and the stubble shaft is driven by the output shaft of the gearbox. The forced leveling device is installed on the frame between the rake plate assembly and the compressor.

If in the process of combined ground preparation, the suspension of agricultural machinery and tools is wider and wider, the fluctuation of locomotive operation is large, and the swing of locomotive operation is large. It is difficult to level the paddy field at one time, with many operations and high cost. Therefore, the deeper the soil, the more serious the compacted layer, the poor soil permeability, the difficult to control the transplanting depth, is not conducive to crop growth.

universal joint cross shaft damage damage:

The main reason: the connection angle between the power output shaft and the combined ground preparation machine is too large. Cross shaft lack of oil. When the combined ground preparation machine buried, the tractor refueled too hard. The horizontal axis swings too much from side to side. Note: Add butter to the cross shaft every 4 hours, and check the temperature rise of the cross shaft frequently during operation. Adjust the connection inclination between the power output shaft and the combined ground preparation machine as required. If the inclination angle is too large, the rear rotary tillage part can be lowered so that the front part of the combined soil preparation machine can raise its head when working. Adjust the left and right adjustment chains and lock them. When the combined soil preparation machine is just buried, slowly increase the throttle.

The stubble cutter shaft and rotary cutter shaft rotate abnormally or do not rotate.

The main reason: most of the debris around the knife shaft. Bevel gears and bevel bearings are stuck without clearance. After the bearing is damaged, its residue is stuck on the meshing surface of the gear, making the gear unable to rotate. The knife shaft is bent after excessive force, resulting in eccentric bearing. Note: to prevent the knife shaft is entangled by debris. Timely adjust the clearance between the bevel gear and the bevel bearing. Avoid the residues of damaged bearings from getting stuck on the gear meshing surface. To prevent the knife shaft force is too large, keep the bearing concentric. When working on the ground, it is necessary to check and eliminate the stubble cutter shaft and rotary cutter shaft to prevent serious accidents such as cracking of the box.

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.
