Abstract
可连续测量土壤机械阻力的深松铲。本实用新型公开了一种可连续测量土壤机械阻力的深松铲，其目的是测量土壤机械阻力。位移传感器用来测量深松铲的耕作深度，它安装在机架与仿形轮之间。深松铲的铲刀与滑块铰接，液压缸与滑块相连接，在耕地阻力不大且铲刀不致于损坏的情况下，液压缸阻止铲刀向后移动，在耕作过程中，若铲刀碰到异物，铲刀所受到的阻力会超过液压缸的设定压力值，液压缸收缩，铲刀会向后移动，避让异物。铲刀上连接有力传感器，用来测量耕地的阻力。
Subsoiler for continuous measurement of soil mechanical resistance. The utility model discloses a subsoiling shovel capable of continuously measuring soil mechanical resistance, and the purpose is to measure soil mechanical resistance. The displacement sensor is used to measure the tillage depth of the subsoiler, which is installed between the frame and the profiling wheel. The shovel of the subsoiling shovel is hinged to the slider, and the hydraulic cylinder is connected to the slider. When the resistance of the cultivated land is small and the shovel is not damaged, the hydraulic cylinder prevents the shovel from moving backward. When the knife touches a foreign object, the resistance of the blade will exceed the set pressure value of the hydraulic cylinder, and the hydraulic cylinder will shrink, and the blade will move backward to avoid the foreign object. A force sensor is connected to the shovel to measure the resistance of the cultivated land.
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.
