Abstract
The utility model discloses a subsoiler capable of continuously measuring soil mechanical resistance. The subsoiler capable of continuously measuring the soil mechanical resistance aims to measure the soil mechanical resistance. A displacement sensor is used for measuring the ploughing depth of the subsoiler and is installed between a machine frame and a contour wheel. A shovel blade of the subsoiler is hinged to a sliding block, a hydraulic cylinder is connected with the sliding block, the hydraulic cylinder prevents the shovel blade from moving backwards under the condition that the ploughing resistance is not large and the shovel blade is not damaged, resistance borne by the shovel blade will exceed the set pressure value of the hydraulic cylinder if the shovel blade encounters foreign bodies in the ploughing process, the hydraulic cylinder contracts, and the shovel blade moves backwards and avoids the foreign bodies. A force sensor is connected to the shovel blade and is used for measuring the ploughing resistance.
Description
Technical field
The utility model relates to a kind of deep soil loosing shovel that can continuous measurement soil mechanical resistance, particularly a kind of can be to the design of foreign matter automatic avoiding apparatus in ploughing, we can be by the situation of change of cylinder pressure value in monitoring avoiding device, judge perching knife and whether encounter foreign matter, the soil mechanical resistance value of rejecting abnormalities, thus measure more accurately soil mechanical resistance value.
Background technology
What kind of technological means no matter traditional soil mechanical resistance assay method adopt, and the soil mechanical resistance value collecting is only confined on the point of some dispersions in farmland, and precision will be very limited, and the course of work is intermittent, and testing efficiency is not high.Although telemetry can be broken away from heavy frame for movement, minimum to the destruction on ground, due to the complexity of soil, only carry out at present soil sample research in laboratory, do not possess the condition in field application.
Utility model content
In order to overcome the deficiency of said method, the utility model provides a kind of deep soil loosing shovel that can continuous measurement soil mechanical resistance, and this deep soil loosing shovel can be measured soil mechanical resistance continuously, exactly.
The technical scheme that the utility model adopts is: deep soil loosing shovel that can continuous measurement soil mechanical resistance comprises frame (1), power sensor (2), trifilar suspension frame (3), displacement transducer (4), contour wheel (5), perching knife (6), safety pin (7), hydraulic cylinder (8), slide block (9), this deep soil loosing shovel is connected with tractor by trifilar suspension frame (3), realize the continuous measurement to soil mechanical resistance, hydraulic cylinder (8) tailstock is arranged on two channel-section steels in the middle of frame (1), piston rod is connected with slide block (9), perching knife (6) is hinged with slide block (9), power sensor (2) is used for measuring the resistance of ploughing, it is arranged between perching knife (6) upper end and safety pin (7), the in the situation that at arable land resistance, little and perching knife (6) being unlikely damage, hydraulic cylinder (8) stops perching knife (6) to move backward, in cultivating procedure, if perching knife (6) is encountered foreign matter, the suffered resistance of perching knife (6) can exceed the setup pressure value of hydraulic cylinder (8), hydraulic cylinder (8) shrinks, perching knife (6) moves backward, dodge foreign matter, measure the now force value of hydraulic cylinder (8), as the foundation of rejecting unusual soil resistance value.Displacement transducer (4) is used for measuring the tilth of deep soil loosing shovel, and it is arranged between frame (1) and contour wheel (5).
Compared with prior art, the beneficial effects of the utility model are: (1) has the design of foreign matter automatic avoiding apparatus in arable land; (2) complete machine structure is simple, can realize easily installation and the replacing of parts, is convenient to safeguard; (3) in perching knife (6) and power sensor (2) junction, adopt safety pin (7) to connect, can effectively protect the safety of critical component; (4) overcome conventional method and measured the inefficient problem of soil mechanical resistance.

Embodiment
Be illustrated with regard to embodiment of the present utility model below in conjunction with accompanying drawing:
In Fig. 1, the utility model is by frame (1), power sensor (2), trifilar suspension frame (3), displacement transducer (4), contour wheel (5), perching knife (6), safety pin (7), hydraulic cylinder (8), slide block (9) composition, this deep soil loosing shovel is connected with tractor by trifilar suspension frame (3), realize the continuous measurement to soil mechanical resistance, hydraulic cylinder (8) tailstock is arranged on two channel-section steels in the middle of frame (1), piston rod is connected with slide block (9), perching knife (6) is hinged with slide block (9), the in the situation that at arable land resistance, little and perching knife (6) being unlikely damage, hydraulic cylinder (8) stops perching knife (6) to move backward by slide block (9), in cultivating procedure, if perching knife (6) is encountered foreign matter, suffered resistance can exceed the setup pressure value of hydraulic cylinder (8), hydraulic cylinder (8) shrinks, slide block (9) slides backward in channel-section steel, perching knife (6) moves backward with slide block (9), play the effect of dodging foreign matter, measure the now force value of hydraulic cylinder (8), as the foundation of rejecting unusual soil mechanical resistance value.Power sensor (2) is used for measuring the resistance of ploughing, it is arranged between perching knife (6) upper end and safety pin (7), because perching knife (6) and slide block (9) are hinged, perching knife (6) is in the time of farming, and the soil mechanical resistance that perching knife (6) lower end is subject to just can record by the power sensor (2) of perching knife (6) upper end.Displacement transducer (4) is for measuring the tilth of deep soil loosing shovel, it is arranged between frame (1) and contour wheel (5), contour wheel (5) contacts with ground all the time, the length of displacement transducer (4) changes with the tilth of deep soil loosing shovel, thereby measures the tilling depth of deep soil loosing shovel.
In Fig. 2; power sensor (2) is arranged between perching knife (6) upper end and safety pin (7); when perching knife (6) is encountered foreign matter; when the effect of dodging of hydraulic cylinder (8) could not make perching knife (6) effectively dodge out foreign matter; safety pin (7) disconnects, the safety of protection critical component.
