Offset disc
Disc offset is a type of tillage machine that consists of a number of concave or convex discs. These discs, mounted vertically on individual axles, flatten and mix the soil as they rotate. Due to the ability to adjust the angle of the discs, the offset disc can be used for all types of soil and different conditions.
Technical specifications
Number of discs: Offset disc comes in different models with different number of discs. The number of disks affects the working width of the device and its penetration rate in the soil.
Diameter of disks: The diameter of disks in the offset disk is usually between 20 and 26 inches.
Weight: The weight of the offset disc varies between 500 and 1000 kg depending on the model and the number of discs.
Suspension system: The offset disc is equipped with a suspension system that helps the device to move smoothly and evenly on uneven terrain.
Disc angle adjustment system: The offset disc is equipped with a disc angle adjustment system that allows you to adjust the angle of the discs according to the type of soil and the conditions you want.
PTO system: The offset disc is connected to the tractor through the PTO system.
Benefits
Quick and complete soil preparation: The offset disc, with the rotational movement of the discs, completely flattens and mixes the soil and provides a suitable substrate for planting seeds.
Weed control: By cutting the roots of weeds, the offset disc prevents their growth and thus helps to reduce the consumption of pesticides.
Increasing soil fertility: By flattening the soil, the ventilation and penetration of water and air in it increases, which in turn helps the better absorption of nutrients by plants and increases the fertility of the soil.
Reducing soil erosion: By creating a smooth and uniform surface on the soil, the offset disc prevents its erosion by wind and water.
Disk applications
Earth preparation for planting various agricultural products: Offset disc is used to prepare the land for planting grain seeds, oilseeds, sunflowers and other agricultural products.
Burying plant residues: The offset disk is used to bury plant residues in the soil and convert them into usable nutrients for plants.
Weed control: Offset disc is used to eliminate weeds in agricultural fields and prevent them from competing with crops.
Types of offset disc connection to tractor
Disc offsets are generally divided into two categories: riding and traction, each of which has its own type of connection to the tractor:
1. Ride's offset disk
Three-point connection: This type of connection is the most common type of connection for mounted offset discs. In this method, the offset disc is connected to the three connection points on the rear of the tractor. These connection points are usually located under the tractor's power take-off and on both sides of it. The three-point connection provides more stability and stability to the offset disc and allows you to use a greater working depth.
2.. The tensile offset disk
Connection to the strap: this type of connection is common for tension offset discs. In this method, the offset disk is connected to the tractor's tie rod. Malband is a metal rod that is located at the rear of the tractor and is used to connect traction agricultural tools such as offset disc, plow, etc. It is easier to connect to the harness than the three-point connection and requires a PTO with less capacity.
What is the Type Bar?
In drip irrigation systems, in addition to drip nylon, tape is also one of the required equipment. Thin strips of polyethylene that are soft and completely flexible. When the water enters from the tank, the strips are filled and after the irrigation is finished, they become flat. Since the tapes are installed near the roots of the crops to clearly irrigate the area around the plant, the water will be used optimally and will not be wasted. Also, less manpower is needed to irrigate the fields or the land, which leads to a reduction in the costs of the farmer or the land owner. The drip irrigation method was first used by a Japanese person for his house pots, but then it was implemented and implemented on a wider scale in Germany and then in Australia.
Types of irrigation type strip
Zigzag stitching or seams
license plate
The difference between these two types is in the holes or apertures of the dropper, which are called plaques. The band of the type plate model has a dropper at different distances from which the water comes out and falls to the ground. But in the zigzag model, there is no hole, and the water pressure leads to the breaking of the zipper wall like a strip and its exit. It should be noted that the water pressure inside the pipe depends on the thickness of the strips, and the lower the thickness, the lower the water pressure should be.
The advantages of using the type tape in the drip irrigation system:
Optimal water consumption
Uniform irrigation throughout the land
Keeping the soil moist for a longer period of time
Reduction of manpower and cost
Can be used in any season
Can be used in agricultural land with different sizes
Easy to install and can be reused after collecting the strips
Uniform growth of seeds and crops
Can be used for row and parallel crops
Widely used for growing crops with summer nylon
Help reduce soil erosion
Lack of adhesion of algae and mineral deposits to the tape due to its material
