Relevant knowledge of joint ground preparation machine

The combined soil preparation machine is a composite operating machine used in conjunction with large and medium-sized tractors, which can complete stubble, rotary tillage, deep loosening, ridging, suppression and other operations at one time, with high operating efficiency. Tillage and soil preparation machinery has the functions of breaking the bottom of the plough, restoring the structure of the soil tillage layer, improving the ability of soil water storage and moisture conservation, removing some weeds, reducing diseases and insect pests, leveling the surface, and improving the level of agricultural mechanization operations.


The combined soil preparation machine is a multifunctional soil preparation machine, which is composed of a frame, a traction frame, a middle beam, a gearbox, a transmission box, a subsoiler assembly, stubble removal parts and rotary tillage parts. The transmission box is arranged on one side of the frame, and seven gears meshing with each other are arranged in the transmission box. The middle beam is arranged in parallel between the rotary tillage axis and the stubble axis. The beam is equipped with a subsoiler assembly, and the rotary tillage shaft is directly driven by the output shaft of the gearbox. The side output shaft of the gearbox is connected with the input shaft of the gearbox through a universal coupling, the stubble shaft is driven by the output shaft of the gearbox, and a forced leveling device is arranged on the frame between the rake plate group and the ballast. Principle: Install a bulldozer blade under one end of the frame with a hanger, connect a crushing roller frame with a crushing roller at the rear of the frame through an adjusting screw, and hang a belt between the bulldozer blade and the crushing roller Rake with elastic teeth. When working, the shovel scrapes the plowed soil layer, the elastic tooth harrow looses the soil, and the soil crushing roller rolls the soil block to suppress the topsoil. Do not turn over the soil layer during operation. It is a soil preparation machine for finishing.

Advantages of combined land preparation machine

The combined land preparation machine is a newly developed product that will be applied by tractors and other equipment. The product has made good improvements in design and can be adapted to the application of soil components of various structures during use. The failure rate is very low and the operation is very convenient. They are very important for improving soil structure in terms of land use efficiency. Now, how much money can play a very good role in promoting the land work environment. In the process of application, various technologies have improved the structural characteristics of the plough layer without turning over the soil ridge, and at the same time, they have also improved the moisturizing effect of the soil layer and the function of preventing sweat and waterlogging. At the same time, the structural characteristics of the soil have been improved, and the basic production capacity of crops has been steadily improved. If combined with large and medium-sized tractors, multiple operations can be completed at one time, with some obvious and effective advantages.

The combined ground preparation machine has a complex structure. During the application process, experienced personnel are required to operate. If a problem occurs, the operation should be stopped immediately. In order to avoid some surprises, this is all we have explained to you today. I hope our mediation today can help you.

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.
