Abstract
The invention discloses a profiling bionic press roller in order to solve the problems that soil adheres to the surface of the body of a press roller commonly used in the prior art, the compactness of the pressed soil is not even, and the pressing force of the press roller on soil is not sufficient. The profiling bionic press roller comprises a press roller body and a center shaft, bionic elastic pieces are distributed on the surface of the press roller body, a shaft ring is fixedly installed on the center shaft, elastic spokes are installed between the shaft ring and the bionic elastic pieces, the elastic spokes on the roller body are in the shape of a profiled ostrich claw toe outline, and designed according to the process that claw toes make contact with soil in the running process of ostriches, the elastic pieces are inserted into soil in the movement process, not only is good soil fixing effect achieved, but also the press roller can be effectively prevented from sliding, ground profiling is performed through stretching and shrinking of the elastic spokes, the compacting effect on soil is better, and pressure is larger; a nylon layer is formed on the surface of the press roller through heat treatment, and thus soil will not adhere to the press roller in the working process.
Description
Technical field
The invention belongs to the bionical pack roller of a kind of profiling in agricultural machinery technological field.
Background technology
Pack roller is the one of agricultural machinery, and effect is after planting soil to be compressed to compacting, soil density is increased and be beneficial to keep soil moisture, is convenient to seed sprouting and emerges.Before pack roller is not applied, the gravity that peasant steps on soil dependence human body at the sowing rear foot makes soil compress compacting, and such method inefficiency and soil tightness degree are inhomogeneous.People have invented pack roller, are used for substituting manually soil is after planting compressed to compacting.Current pack roller is made up of roller frame and the several rollers that are arranged on roller frame, and the longitudinal axis (being the direction of advance of roller frame) of the axis of its roller and roller frame is perpendicular.When operation, pack roller drives by hitching machinery, on ridge platform after planting, rolls across, and relies on like this gravity of pack roller itself and additional pressure that soil is compressed to compacting.In the time of operation, there is adhesion soil phenomenon in such pack roller; because soil when sowing generally contains larger moisture; such soil has certain viscosity; when pack roller rolls across soil; easily adhesion soil; affect operation quality, when adhesion soil is serious, must shuts down and remove the soil that sticks in pack roller surface.In order to solve adhesion soil issues, people have added rubber sleeve in pack roller outside, between rubber sleeve and pack roller body, there is certain gap, the continuous creeping deformation of rubber sleeve when pack roller rolls, make soil be not easy adhesion on the coat, this method has alleviated the degree of pack roller adhesion soil, but has following shortcoming: 1, rubber sleeve has increased pack roller cost; 2, operation quality is bad, and the soil tight ness rating that pack roller was suppressed is inhomogeneous; 3, pack roller is inadequate to the pressure of soil in work engineering.
Summary of the invention
The object of the invention is to overcome the inhomogeneous and pack roller of soil tight ness rating after the existing adhesion soil of pack roller, the suppression generally using now to the inadequate shortcoming of earth pack power, provide a kind of profiling bionical pack roller, to reach the adhesion degree that reduces soil and pack roller, make to suppress rear soil tight ness rating even, the object that increases the pressure of pack roller to soil, technical scheme of the present invention is as follows:

Below in conjunction with two embodiments, the distribution of the bionical shell fragment 12 to the bionical pack roller of a kind of profiling of the present invention is described further:
In order to prevent pack roller surface adhesion soil in operation process, pack roller roller 4 is heated to 140～260 degrees Celsius, put it into afterwards in the fluid bed that nylon powder is housed, to take out after cooling, surface forms even thickness nylon layer.This processing not only can make pack roller non-stick earth in the course of the work, and can increase wearability and the toughness of bionical shell fragment 12.In addition, also can alleviate the adhesion of pack roller to soil by the bionical shell fragment 12 of trigonometric function curved arrangement.
The present invention according to the geometry of the pawl toe of ostrich and parameter designing can carry out the bionical pack roller of ground profiling, comprise the structure of the bionical shell fragment 12 on pack roller roller 4 and the ground feeler mechanism of its arrangement mode and pack roller.The body structure of ostrich is applicable to running very much, and speed is very fast, running fast, middle ostrich foot still can hold on to soil, have benefited from its distinctive pawl toe geometry and run process median claw toe and soil interaction, these two factors have ensured that ostrich can produce the good native fixation of grabbing in the process of running., the mechanism of ground profiling and pack roller cylinder 4 are combined meanwhile, just as the leg of ostrich and sufficient connection, soil is produced to larger pressure, make it produce the effect of better compacting soil.
In order to solve most of pack rollers to the inadequate problem of ground pressure, the present invention has adopted imitated structure, for connecting the elastic spokes 3 of pack roller cylinder 4 and central shaft 1, fluctuating with ground elongates or shortens, as ostrich leg, in the course of the work shell fragment is produced to larger power, increase the pressure of pack roller entirety to soil.Meanwhile, in the time that bionical shell fragment 12 contacts with soil, bionical shell fragment 12 is compressed, and in the time that bionical shell fragment 12 leaves soil, bionical shell fragment 12 outwards ejects under the effect of elastic spokes 3, soil on pack roller can be shaken off.Its profile modeling is: the frame of pack roller and farm machinery are to be rigidly connected, because pack roller roller 4 and central shaft 1 are to be connected by elastic spokes 3, in the time running into protruding ground, pack roller surface pressure increases, elastic spokes 3 compression degrees increase, and the relative pack roller roller 4 of central shaft 1 of pack roller moves down; In the time running into low-lying ground, pack roller surface pressure reduces, and elastic spokes 3 compression degrees diminish, and the central shaft 1 of pack roller moves on suppression roll surface relatively.Thereby realize the effect of ground profiling.
