摘要:
A method of carrying out renovation works in melioration ditches by means of a multifunction device, that can move inside a ditch space and avoid terrain obstacles occurring in this space, especially including trees and bushes growing on a ditch slope, a ditch bank or a ditch bottom. It is intended for works related to care for melioration ditches and channels and keeping them in a state of technical functionality. The device comprises one-track travel chassis (2), situated under the main frame (13) in its symmetry axis, whereas the side supports (5) with the supporting wheels (4) are situated on both sides of the main frame (13), while the front tool suspension unit (10) and the hydraulic manipulator (11) are situated in front of the travel chassis (2), whereas the hydraulic manipulator (11) is mounted on the main frame (13), above the front tool suspension unit (10), and there is the tool turn-table (14) at the end of the hydraulic manipulator (11), and furthermore, the rear tool suspension unit (15) is situated behind the travel chassis (2), and the operator cab (11) is situated on the main frame (13), between the hydraulic manipulator (11) and the side supports (5), and the motor aggregate (16) is situated behind the side supports (5).

Suspension system for front working tools in a melioration device, intended for carrying out land melioration work, especially at maintenance and renovation of water-courses, including a frame (3), a guide (4), a beam (11) and a lever (13), is characterized in that the guide (4) includes a two-part body (5 and 6), for realization of inclination of a system by means of a hydraulic cylinder (9), where said two-part body (5 and 6) is rotatably fastened on a main pin (2) of the frame (3), the guide (4) being connected with the slidable beam (11) for moving out a working tool by means of a hydraulic cylinder (12), and the slidable beam (11) is additionally connected with the two-row lever (13) for changing angular position of the working tool by means of a hydraulic cylinder (14).
摘要:
A method of measurement of agrotechnical spraying, in which parts of a plant covered with chemical substances, in particular agrochemicals, are analyzed by comparison with references present in a database, characterize in that UV radiation is used in excitation bands 280 nm, 300 nm, 340 nm, 400 nm and 450 nm, exposed cyclically in turn for about 10 milliseconds to perform at least 20 measurements of the spectres of excited luminescence of a sprayed plant sample, after which a plant and chemical substance are identified by comparing the obtained spectra with the references contained in a computer database, and through the analysis of the amplitude of the signals of the chemical substance, its amount on the tested plant sample is determined. The invention enables identification and quantification of the amounts of the substance when spraying cultivated plants with agrochemicals, also after the process of evaporation and after penetration of agrochemicals into plants.
摘要:
A system for automatic scarification and assessment of viability of seeds, characterized in that it comprises an input container (102) for the seeds, connected to an input of a seed transportation path that comprises the following elements arranged in the following sequence: a feeder (103), a length and orientation detector (110), a rotator (120), a positioner (135), a gripper (132), a scarifier (142), a mummification changes detector (150) and a sorter (162) at the output of the path and coupled with seed containers (163, 164, 165).
摘要:
A method of monitoring agrotechnical spraying consisting in detection of the presence in the atmosphere of chemical substances in the form of aqueous aerosols and a system for the application of this method consisting in detecting the presence in the atmosphere of chemical substances in the form of aqueous aerosols, using a transmitter and receiver of electromagnetic waves, characterized in that at least 50 impulses of electromagnetic radiation with a wavelength from 600 to 650 nm, preferably 635 nm, modulated by a square wave, preferably with a filling of 50% and a frequency of 1 kHz is passed through the tested area, and then the amplitude of each pulse from the receiving line is determined and the attenuation of electromagnetic radiation beam is determined, and then the pre-defined coefficients of the attenuation of the radiation beam by a water aerosol of an agrotechnical substance used for spraying serve to designate the concentration of the spray in the atmosphere. The solution according to the invention uses an optical system for measuring the transmission, in which electronic modulation of the light is used.
