General configuration of combined land preparation machine


Combined land preparation machine is widely used in Europe and the United States home of large-scale soil preparation equipment, many well-known agricultural machinery enterprises have produced such products. As a conservation tillage equipment, it has higher efficiency, better moisture conservation effect and better soil layer protection than traditional tillage operations. In some specific cases, farmers will use a combined soil preparation machine to clean up the soil instead of using a pear tool. For example, when planting rootstock crops such as potatoes and carrots in the previous crop and inoculating crops such as corn and wheat, corn and wheat in this case do not require deep loosening of soil as rootstock crops, and there is no stubble that is difficult to deal with in the previous crop, so the soil preparation machine can give full play to its advantages.

Combined ground preparation machine

There are many brands of imported brand land preparation machines on the market. Here is an example of our company's main sales of Reken (Karat) and Amarzonisenius:

1. Anti-overload protection: Various situations often occur in soil operations. Large stones and other debris in the soil will affect the operation and damage the machine. Two anti-overload devices are usually designed for combined ground preparation machines: shear bolts and anti-overload springs.


Anti-overload spring

When the current operator encounters strong resistance during operation, the shear bolt will naturally break, and then the subsoiling hook will be lifted to protect the machine. At this time, the user needs to get out of the car and replace the new bolts to ensure normal operation. However, the spring-type anti-overload device will tighten the spring to avoid debris after encountering resistance, and the shear bolt will be triggered when the spring reaches the upper limit. Usually the upper limit of the spring lifting tool is 25-30cm, after which the shear bolt is triggered. Compared with the former, the latter has advanced configuration, which can reduce the maintenance cost and number of times caused by mechanical overload. Usually the latter is equipped with a land preparation machine price is also relatively high.


2. Loosen the hook type plough: According to the different requirements of the tillage depth and different soil conditions, the combined soil preparation machine needs to cooperate with different types of plough pieces. Taking the Amasonius subsoiling machine as an example, the hook tiller of the subsoiling machine can be divided into four types: duck claw type, wing type, ordinary type and extension type.


Duck claw type: 3-10cm deep shallow stubble crushing stirring ability, weeding ability, can eradicate shallow grass seeds.

Wings: 8-12cm deep in the shallow stubble crushing mixing ability.

General formula: ploughing depth 10-20cm plowing knife is suitable for processing most of the less stubble soil, wide range of application.

Lengthening: ploughing depth 12-30cm deep loosen soil, the material is harder than the first three; High power consumption and poor mixing ability.


3. Soil moisture separator

The main function of the soil moisture separator is to level the loose soil and prepare it for the next soil operation. Usually there are three types of soil moisture containers: spring type, disc type and notched disc type.

Spring: low price, simple structure, power saving during operation, suitable for mild to moderate soil, no stubble. With anti overload device, low maintenance cost. Disc type: suitable for medium and heavy clayey soil, with certain stubble-extinguishing effect. The bearing is fixed with rubber to prevent overload, with high power and high cost.


Notch disc type: suitable for medium and heavy cohesive soil, with good stubble removal and soil mixing effects. The bearing is fixed with rubber to prevent overload, with high power and high cost.


4. Pressure roller height adjuster


According to different tillage depth and soil conditions, users need to adjust the height of the soil moisture collector and the pressure roller to obtain the desired effect. Generally, the two regulators can be divided into manual adjustment and hydraulic automatic adjustment. Since adjustments are irregular, simple manual adjustments are generally used to reduce procurement costs. However, in some large plots, due to the different soil conditions in different locations of the same plot, hydraulic adjustment can achieve fast and convenient height adjustment.

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.
