porn tbes,The traction heavy disc harrow is mainly used for plowing of uncultivated land. It is also used for crushing soil and leveling operations on cultivated land.

Brief introduction of disc heavy harrow

sex.hd,A disc heavy harrow is a tillage tool with a rake group composed of a plurality of concave discs fixed on a horizontal shaft as a working part. It has strong adaptability to heavy soil, wasteland, and weedy plots. It can also be used for stubble removal before plowing, harrowing after plowing, loosening the soil, etc. When the disc heavy harrow works, it can mix the surface fertilizers and pesticides with the surface soil. So as to achieve the effect of leveling and moisture preservation.

The structure of the disc heavy harrow

The disc harrow is generally composed of rake group, rake frame, deflection adjustment mechanism, and hooking device.,hotvideos

Rake group

desiaunty,The rake group is composed of rake blades, intermediate pipes, square shafts, bearings, and scrapers. Harrow blades are generally spherical discs. There are two types of discs, full blade, and notched blade. The former is simple to make and easy to grind. The latter has a strong ability to enter the soil. This helps cut dirt and stubble weeds. And it is widely used in heavy harrows for heavy soil tillage.

And the center of the blade is a square hole through the square shaft. When working, the harrow blades rotate together with the square shaft. Fasten it with nuts on both ends of the square shaft. The rake group is pierced on the square shaft to form a whole. Which is connected with the rake frame through a bearing, and the rake blades on the same shaft are separated by an intermediate tube. In order to remove the dirt attached to the rake blades, a scraper is installed on the beam of the rake group.,hot mom xxxx

Rake frame

The rake frame is used to install the disc harrow group, adjustment mechanism, and hooking device, and other components. Some rake frames are also equipped with a load box so that counterweights can be added when necessary to increase and maintain the depth of the rake. The deflection angle adjustment mechanism is used to adjust the deflection angle of the disc harrow to meet the requirements of different rake depths.,bts hd

Deflection adjustment mechanism

Angle adjusters include lead screw type, tooth plate type, hydraulic type, bolt type, pressure plate type, and hand lever type. The deflection adjustment mechanism of the traction rake tooth plate is composed of upper and lower slide plates, tooth plates, brackets, and other parts. The bracket is fixed on the traction main beam, the upper and lower slide plates are fixed with the traction frame, and can move along the main beam, and the moving range is limited by the bracket at the end of the tooth plate. A hand lever can be used to clamp any gap on the tooth plate on the bracket, and a series of linkage mechanisms make the rake group swing around the hinge joint to obtain different deflection angles.,porn vegina

Hooking device

hxmaster,The hitch is a disc harrow connected to the tractor through a traction device or a suspension device.

Working principle of disc heavy harrow

Groups of concave discs are used as working parts. The blade edge plane is perpendicular to the ground and has an adjustable deflection angle with the forward direction of the unit. During operation, the harrow blades roll forward under the action of tractor traction and soil reaction force. The blades of the harrow blades cut into the soil to cut off grassroots and crop residues, and the soil is raised to a certain height along the concave surface of the harrow blades and then flipped down.,bbw milf

Configuration form of disc heavy harrow

According to the configuration of the rake group, we can divide it into three types: single row opposed type, double row opposed type, and offset type.,hotsex

Single row opposed type

The left and right sides of the rake components arrange in a single row. And the left and right rows each consist of one or more rake groups with opposite concave surfaces. It is used for flat land of irrigated land, stubble after harvest, and shallow plowing of fallow land.,beeg 20

Double row opposed type

hotvideos,There are two columns before and after. Each column is symmetrically arranged by two rows of rake groups on the left and right. The concave surfaces of the discs of the front two rows of rake groups are opposed to each other. The discs of the rear two rows of rake groups locate between the two discs of the front row of rake groups. And they are opposite to the concave surface. In order to prevent the left and right rake groups from being left at the junction of the left and right rake groups of the opposed rakes, the left and right rake groups are staggered in some opposing rakes.

Offset type

It consists of two rows of rake groups with opposite concave surfaces of the discs in the front and the back. Because the lateral force of the front and rear rake groups is balanced with the traction. Thus the width centerline of the rake can deviate far from the longitudinal axis of the tractor during operation. So it is called an offset rake. The offset of the wide offset rake can reach more than 3 meters. When used in an orchard, you can extend the offset rake to work under the canopy where the tractor cannot enter. Because the offset rake has no missing tillage zone, it is also widely used in field operations.,d xxx

How to choose a disc heavy harrow

The 1BZ series hydraulic heavy-duty disc harrow has high working efficiency and strong soil penetration ability. So it can loosen the soil after ploughing. This kind of rake well adapt to sticky soil, wasteland and weedy plots. It is welded by square tubes, with simple structure and good rigidity. The rake also equips with hydraulic lifting rubber wheels. And it is convenient for transportation. Besides it has a small turning radius. So it can greatly improves the production efficiency and service life of the rake.,aaa xxx

Correct use and maintenance of hydraulic trailed heavy-duty harrow

During use, check the technical condition of the rake blade, scraper, square shaft, bearing, angle adjuster, and various connecting parts frequently. Especially the end nuts of the disc harrow and the fixing bolts of each bearing. And whether they are loose. Find and tighten it in time. And remove the weeds and dirt on the patch in time.,bbw milf

After the operation, clean and overhauled the rake group of the disc heavy harrow. And then stored in a flat and dry warehouse. When storing the disc harrow, pad the harrow with wooden blocks, and smear the harrow with waste butter or waste engine oil to prevent corrosion.,masterbed

hotsex,When transporting over a long distance, install a transport wheel on the disc harrow group to keep the disc harrow group off the ground. If not use the transport wheel, it will damage the disc harrow group prematurely. When transporting in the field or near dirt roads, adjust the inclination angle to zero.
