disc harrowType: According to the coupling mode with the tractor, the disc harrow can be divided into three types: traction, suspension and semi-suspension. Heavy rake is generally traction or semi-suspended, there are three types of light rake and medium rake.
Traction disc harrow. Traction disc harrow is composed of traction frame, hydraulic system, harrow frame, harrow group, transportation wheel, etc. Some rakes are also equipped with a counterweight box.
Suspended disc harrow. The suspended disc harrow is generally composed of a harrow group, a harrow frame, a suspension frame and a deflection angle adjustment mechanism.
Semi-suspended disc harrow. The semi-suspended disc harrow is composed of suspension rack, hydraulic system, harrow frame, harrow group, transportation wheel, etc. Some rakes are also equipped with a counterweight box.

The disc harrow is a ground preparation machine, which uses multiple sets of concave discs as working parts, the blade plane is perpendicular to the ground, and the random group forward direction has an adjustable deflection angle. Compared with plows, it requires less power and higher operating efficiency. It can "rake instead of plowing", save energy, and can avoid over-tilling the soil. After raking, the soil can be fully mixed, which can promote the activity and chemical decomposition of microorganisms in the soil.
The disc harrow is mainly used for tilling broken soil and leveling, and can also be used for stirring soil, weeding, mixing fertilizer, shallow tillage, loosening soil before sowing, covering seeds after sowing, etc. Widely used in traction topsoil tillage equipment.
When the disc harrows, under the action of traction, the disc rolls forward, and under the action of the gravity of the harrow and the reaction force of the soil, it cuts into the soil to a certain depth. When the rake blade is rolling, under the combined effect of the blade and the surface of the rake blade, the soil is pushed and shoveled, and the soil undulates along the concave surface of the rake blade, which plays the role of breaking the soil, turning the soil and covering the soil.
The disc harrow is composed of a harrow frame, a harrow group, a traction or suspension device, and a deflection adjustment mechanism. In order to increase the depth of the soil, some light and small rakes are equipped with counterweight boxes on the rake frame. When installing the disc harrow group, the deflection angle of the disc harrow group should be fixed at a better position. When shallow tillage is required, wheels controlled by hydraulic cylinders limit the depth. The towed rake is usually equipped with a device that can automatically adjust the transport state and manually fine-tune the working state on the towing device. With the help of the lifting of wheels and connecting rods, the rake frame always remains horizontal. The commonly used disc harrow has the following configuration: disc harrow single row The left and right sides of the rake group are arranged in a row, and the left and right rows are respectively composed of one or more rake groups with opposite concave surfaces. It is used for flats of irrigated land, stubble after harvest and shallow cultivation of fallow land. Front and rear two rows: each row of disc harrows is symmetrically arranged by two rows of left and right harrows. The concave surfaces of the discs of the first two rows of tine groups are opposite each other. The discs of the rear two rows of rake sets are located between the two discs of the front rake set and opposite the concave surface. In order to avoid the left rake group and the right rake group of the opposite rakes of the disc rake leaving missing areas at the junction of the left and right rakes, some of the opposite rakes interleave the left and right rakes.

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.
