When the platform 5 is inclined, the mass ball 26 can move from the middle part of the cylinder to the edge of the cylinder along the channel 41 under the action of gravity of the mass ball 26, and when the mass ball 26 approaches the Hall sensor 27, the Hall sensor 27 controls the supporting cylinder 17 to work through the control system so as to level the platform 5. That is, when the mass ball 26 made of a magnet approaches the hall sensor 27, the output signal of the hall sensor 27 is changed, and the control system controls the corresponding support cylinder 17 to operate using the changed signal.
It should be noted that, the supporting cylinders 17 are in one-to-one correspondence with the hall sensors 27, when the mass ball 26 approaches one of the hall sensors 27, the hall sensor 27 controls the supporting cylinders 17 corresponding to the hall sensor 27 to work, so that one end corresponding to the platform 5 is lifted up by the supporting cylinders 17, meanwhile, the other two supporting cylinders 17 can work simultaneously, the other two ends of the platform 5 are pulled down, finally, the platform 5 is enabled to be horizontal, the soil sampler 18 is ensured to be vertically inserted into soil for sampling, and the soil sample of each level with ideal depth cannot be obtained after the soil sampler 18 is prevented from being inclined greatly.
In the present embodiment, after the user moves the vehicle body 3 to the soil sampling detection area, the water pump 1 is started first, the water pump 1 pumps the water in the water tank 2 into the water pipe 25, and the water is ejected through the nozzle 251 on the water pipe 25, so that the soil in the sampling detection area is wetted, and the insertion of the first plate 24, the second plate 19, and the soil sampler 18 is facilitated.
Because the ground condition of the soil detection area is complex, the platform 5 on the stationary vehicle body 3 is generally not in a horizontal state, if the soil sampler 18 is directly inserted into the soil, the condition that the inclination angle of the soil sampler 18 is large exists, so that the soil sampler 18 cannot be smoothly inserted into the target depth to obtain a soil detection sample with the target depth, and most of soil samples with shallow depth are obtained by the inclined soil sampler 18, so that sample interference is caused in the soil detection process, and the soil detection precision is affected. That is, the soil sampler 18 inserted obliquely into the soil cannot obtain a multi-layered soil detection sample of a target depth, affecting the soil detection efficiency and result. Therefore, at this time, whether the platform 5 is horizontal is judged by the horizontal sensor 4, when the platform 5 is inclined, the mass ball 26 in the horizontal sensor 4 moves along the channel 41 towards the inclined direction of the platform 5, and when the inclination angle of the platform 5 is larger, the mass ball 26 approaches the corresponding hall sensor 27 along the channel 41, so that the hall sensor 27 starts the corresponding supporting cylinder 17 to work, and the platform 5 is leveled. It should be noted that, the hall sensor 27 is a magnetic field sensor manufactured according to the hall effect, the hall sensor 27 in the invention is a linear hall sensor, the linear hall sensor 27 is arranged at the edge of the cylinder in the horizontal sensor 4, the magnetic induction intensity is zero, the point can be used as the zero point of displacement, when the mass ball 26 moves along the channel 41, the hall sensor 27 has displacement along the channel 41, the hall sensor 27 has a voltage output, the voltage is proportional to the displacement distance, the voltage change of the hall sensor 27 is utilized to sense the displacement change of the mass ball 26, if the displacement change of the mass ball 26 exceeds a set threshold, i.e. the mass ball 26 is quite close to the edge of the cylinder, the voltage of the hall sensor 27 is higher than the set voltage, the control system judges that the platform 5 is inclined, and simultaneously the control system controls the supporting cylinder 17 to work so as to level the platform 5.
Namely, the using method of the horizontal sensor comprises the following steps:
step S1: when the platform 5 is inclined, the mass ball 26 can move from the middle part of the cylinder to the edge of the cylinder along the channel 41 under the action of the gravity of the mass ball 26, and when the mass ball 26 approaches one of the Hall sensors 27, the Hall sensors 27 control the supporting cylinder 17 to work through the control system;
step S2: when the mass ball 26 approaches one of the hall sensors 27, the approaching hall sensor 27 transmits a signal to a control system, and the control system controls the corresponding supporting cylinder 17 to work, so that the supporting cylinder 17 jacks up one end corresponding to the platform 5;
step S3: simultaneously with the step S2, the other two supporting cylinders 17 also work simultaneously, the other two ends of the platform 5 are pulled down, and finally the platform 5 is leveled.
The angle of the first plate 24 is then adjusted according to the depth of the soil to be sampled and detected. Specifically, the stepping motor 8 is started, the output shaft of the stepping motor 8 drives the worm 20 to rotate, the worm 20 is matched with the worm wheel 23, so that the worm wheel 23, the rotating shaft 22 connected with the worm wheel 23, the connecting piece 6, the first cylinder 7 and the first plate 24 rotate, and the angle of the first plate 24 is fixed by utilizing the self-locking property of the worm 20 of the worm wheel 23. The first cylinder 7 and the second cylinder 10 are started, the first plate 24 is obliquely inserted into the detection soil, the second plate 19 is vertically inserted into the detection soil, after the first plate 24 and the second plate 19 are close to contact, the vehicle body 3 moves, and the soil in the surrounding area of the first plate 24 and the second plate 19 is taken out and returned to the original point. At this time, the sampling cylinder 13 is started, and the sampling cylinder 13 pushes the soil sampler 18 to vertically insert into the soil for sampling and detection. Because the soil of geotome 18 one side is taken out by first plate body 24 and second plate body 19, the resistance of geotome 18 is reduced greatly at the in-process that stretches into soil and receives around, and the geotome of being convenient for inserts soil fast and smoothly and takes a sample, makes the soil sample more smooth and easy, has also improved the efficiency of sampling detection simultaneously.
According to the invention, after the soil on one side of the soil sampler 18 is taken out by the first plate body 24 and the second plate body 19, the soil sampler 18 is inserted into a target area close to the soil after the soil is taken out by the sampling cylinder 13, so that the resistance of surrounding soil received by the soil sampler 18 in the process of extending into the soil is reduced, and the sampling and detecting efficiency is improved. On the other hand, one of the ends of the triangle of the platform 5 is provided with a level sensor 4. After the platform 5 is inclined, under the gravity action of the mass ball 26, the mass ball 26 can move from the middle part of the cylinder to the edge of the cylinder along the channel 41, after the mass ball 26 is close to the Hall sensor 27, the Hall sensor 27 controls the supporting cylinder 17 to work through the control system, the platform 5 is leveled, the platform 5 is finally enabled to be horizontal, the soil sampler 18 is ensured to be vertically inserted into soil for sampling, and soil samples of all levels with ideal depth cannot be obtained after the soil sampler 18 is prevented from being inclined greatly.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
