On the soil surface for processing prior to its first detection of surface roughness in order to select equipment leveling. A surface roughness tester, including the light source and light source installed in the concave mirror in the optical path, the light path in concave mirror with the concave mirror set of the reflected light by vertical partitions, partition by the optical path set up traps with spectrophotometry board under test into a certain point of view of the workpiece in the workpiece under test in the reflected light path is also set up the workpiece under test in parallel with the photoelectric measuring board, photoelectric board measuring the reflected light path is also connected in turn set up amplifiers, analog-to-digital conversion and a computer. The utility model issued by the light scattering light after reflection by the concave mirror as a parallel bar, separated by the partition by multi-beam into parallel light, the parallel light reflection by the surface under test measured in photoelectric board, photoelectric board will be measured received light intensity of the reflected light is converted to the corresponding electrical signal by the amplifier into a standard electrical signal, then converted to analog and digital signal processing entered into the computer came to the conclusion that the measured surface roughness . Soil scattering and thermal radiation properties and surface roughness and soil moisture content is closely related to the coarse-grained soil and artificial rough surface plate loads in monotonous mechanical properties than the systems studied. From the perspective of macro-and meso-2 were measured, analyzed and summarized the coarse-grained soil-structure contact surface of the basic mechanical properties and deformation mechanism. Experiments show that: the thickness of the contact surface is about 5 6 times the average particle size; contact surface when shear shows that the relative normal displacement, the changes in trends and the normal stress-related; contacts simultaneously decomposed into the deformation and mutual effects of soil-structure at the junction of the slip surface as well as the structure of surface deformation of the soil near the surface in the structural constraints under the two parts of the shear deformation, which is caused by the relative displacement of the main reasons law; the structure of surface roughness, soil types and the normal stress and other factors on the mechanical properties of the contact surface has an important influence. Soil roughness measurement methods, including the following steps: 1) land in the target random sampling, random fixed points, the distance between two points for the L; 2) at fixed points where the straight line, the tight rope of soft inelastic affixed to the rough surface soil flat, access to soft绳拉straight between two points the distance L ; 3) followed by determination of each quadrat analogy; 4) According to data measured in each quadrat the soil roughness Ci = Li / L (i = 1,2,3 . n), then the whole objective of the land come to the soil type roughness see. Soil roughness measurement of the invention simple and practical, to meet the agricultural production and soil erosion management needs. Objects will be measured at CMM space objects will be measured on the coordinates of the location of the measuring point, according to the spatial coordinates of these points, the value of the measured object is obtained by calculating the geometric size, shape and location. The formation of the traditional method of dealing with the use of flat-panel刮平, which will lead to strip the soil surface scratches, as well as rugged Article waves, thus affecting the experimental measurement of soil quality spectrum. Soil surface treatment plant designed to improve the traditional method of formation of many problems, so that even the formation of the surface soil samples, uniformity, and optimize the experimental process.Plane by the host machine (control system) and the mobile arm reciprocating components. The host can set up a rotation into linear motion of the eccentric wheel slider-crank mechanism, the rotary motor can be turned into mobile arm of the reciprocating linear motion, and the mobile arm range of motion and speed can be adjust. The idea of this design are a source of inspiration Soil surface treatment plant design is the guiding ideology of small screen moving back and forth in place of the original formation of the scraper handle movement to increase the take-off and landing so that the soil be able to multi-body formation, to achieve a more level soil surface, more evenlyDevices based on practicality, simplicity, consider initially selected as the driving force input manually. Experiments: the mobile frequency of 180 workstations / min, to achieve the purpose of soil formation. Comprehensive test摇柄speed of 60 100 r / min, through a reasonable transmission requirements can be achieved formation;Moving can be realized there are many institutions, the choice of contrast, the slider-crank mechanism was chosen as the level of movement of table drive mechanism. Slider-crank mechanism is a connecting rod to crank through a continuous rotation into a reciprocating movement of the slider body, which is widely used in engineering, such as internal combustion engines, reciprocating pumps, air compressors and press and so on. Slider-crank mechanism is a four-bar linkage of the evolution of forms, from a number of rigid components with low-vice (rotary vice, mobile, deputy) from a body access. Commonly used in the rotary movement will transform crank for reciprocating linear motion of the slider; or the slider back and forth linear motion is converted to rotary movement of the crank. The main advantage is its simple structure, easy to manufacture, reliable practice in engineering a wide range of applications. Slider-crank mechanism of the characteristics of exercise is known to the component size parameters, location parameters and the original movement of moving parts, the research institutions on the remaining components of the trajectory points, displacement, velocity, acceleration and so on, in order to evaluate whether to meet work performance requirements. Whether the occurrence of interference, such as movement. In the device, not entirely through the intermittent drive gear and the leading role of guide, to achieve the level of the surface of the table in the front and rear, about the interaction. Gear is not entirely by the ordinary involute gear bodies evolved intermittent movement of a body. With the general body involute gear tooth difference is not covered the entire circumference, the constant round of the initiative into a continuous rotation of the intermittent movement driven round. Not widely used gear mechanism, as compared with other space agencies, the move to stop time limits from the institutional structure, simple structure, easy manufacturing, the drawback is driven round the whole in each movement, the speed of both mutations, the impact of more large, it is generally used for low-speed, light load of occasions.Through the transmission, the size of box and rail design, final design of the connecting rod length, the entire body with reasonable arrangements for movement to the work of installation requirements. Lifting devices lifting screw body parts. Screw lifting body structure is simple and smooth movement. Treatment plant from the soil surface is not completely gear transmission, crank-slider mechanism, and screw guide body movements, as well as five-part box, through the coordination of the various parts, before and after the realization of the table lifts up and down movement and interaction movement.The institutions selected for the ball slider rail agencies, rolling and sliding guide rail, it has the following advantages: the friction coefficient of small, dynamic and static friction coefficient is very close. Therefore, the friction of small, start-up light, movement sensitive, difficult to crawl, wear small, to maintain good accuracy and long life. Have a high repeat positioning accuracy, smooth movement. Lubricating oil may be, a simple lubrication system. Rail rolling compared with the sliding rail, anti-vibration poor, but they can raise through pretightening, structural complexity, high cost. Institutions for the two sets of gear teeth incomplete bodies, including a set of a set of straight-tooth bevel gear to enable them to achieve the intermittent movement. Institutions make use of screw up and down movement of the table, at the same time through the spiral of self-locking function of institutions play a supporting role. Spiral will be mainly used to drive rotary movement into linear movement, at the same time the transmission of energy and power, or to adjust the location of parts of each other. Sometimes used to linear motion into rotary movement.The layout of the device structure: handle input power, followed by the bevel gear transmission, with the bevel gear is connected to a slider-crank mechanism, they completed the move around. The other axis is a straight movement gear also has a slider-crank mechanism before and after the completion of the movement direction. Cylindrical guide rail 14 is installed on, and take-off and landing on their bodies and take-off and landing on the table through the table to connect fastening nut. Another set of four columns on a guide-bar mechanism in order to achieve independence before and after the reciprocating movement around.
