After the platform 5 is inclined, under the action of the gravity of the mass ball 26, the mass ball 26 can move from the middle of the cylinder to the edge of the cylinder along the channel 41, and after the mass ball 26 is close to the hall sensor 27, the hall sensor 27 controls the support cylinder 17 to work through the control system 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 correspond to the hall sensors 27 one to one, when the mass ball 26 is close to one of the hall sensors 27, the hall sensor 27 controls the supporting cylinder 17 close to the hall sensor 27 and corresponding to the hall sensor 27 to work, so that the supporting cylinder 17 jacks up one end of the platform 5, and meanwhile, the other two supporting cylinders 17 can also work simultaneously, pull down the other two ends of the platform 5, and finally make the platform 5 horizontal, so as to ensure that the soil sampler 18 can be vertically inserted into soil for sampling, and prevent the soil sampler 18 from being inclined greatly and being incapable of acquiring soil samples of all levels of an ideal depth.
In this embodiment, after the user moves the vehicle body 3 to the soil sampling and detection area, the water pump 1 is first started, the water pump 1 pumps the water in the water tank 2 into the water pipe 25, and the water is sprayed out through the nozzle 251 on the water pipe 25 to wet the soil in the sampling and detection area, thereby facilitating the insertion of the first plate 24, the second plate 19, and the soil sampler 18.
Because the ground condition in soil detection region is complicated, the platform 5 on the automobile body 3 that comes to rest this moment is generally not the horizontality, if directly insert geotome 18 in the soil, there can be the great condition of geotome 18 inclination for geotome 18 can not insert the target depth smoothly, obtain the soil detection sample of target depth, again because the most soil samples of shallow depth that the geotome 18 of slope obtained are, at the in-process that soil detected, cause the sample to disturb, influence the precision that soil detected. That is, the soil sampler 18 inserted obliquely into the soil cannot obtain a multi-level soil test sample of a target depth, which affects soil testing efficiency and results. Therefore, whether the platform 5 is horizontal or not is judged through the horizontal sensor 4, after the platform 5 inclines, the mass ball 26 in the horizontal sensor 4 moves towards the inclination direction of the platform 5 along the channel 41, and when the inclination angle of the platform 5 is larger, the mass ball 26 is close to 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 is a magnetic field sensor manufactured according to the hall effect, the hall sensor 27 in the present invention is a linear hall sensor, the linear hall sensor 27 is placed at the edge of the cylinder in the horizontal sensor 4, the magnetic induction intensity of the linear hall sensor is zero, this point can be used as the zero point of the displacement, when the mass ball 26 moves along the channel 41, it is equivalent to that the hall sensor 27 has displacement along the channel 41, at this time, the hall sensor 27 has a voltage output, the voltage magnitude is in direct proportion to the displacement distance magnitude, the voltage variation of the hall sensor 27 is used to sense the displacement variation of the mass ball 26, if the displacement variation of the mass ball 26 exceeds the set threshold, that is, the mass ball 26 is quite close to the edge of the cylinder, at this time, the voltage of the hall sensor 27 is higher than the set voltage, the control system judges that, meanwhile, the control system controls the supporting cylinder 17 to work to level the platform 5.
Namely, the use method of the horizontal sensor comprises the following steps:
step S1: when the platform 5 is inclined, under the action of the gravity of the mass ball 26, the mass ball 26 can move from the middle of the cylinder to the edge of the cylinder along the channel 41, and when the mass ball 26 is close to one of the hall sensors 27, the hall sensor 27 controls the support 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 the control system, and the control system controls the corresponding supporting cylinder 17 to work, so that the supporting cylinder 17 jacks up the corresponding end of the platform 5;
step S3: at the same time of the step S2, the other two supporting cylinders 17 are also operated at the same time, and the other two ends of the platform 5 are pulled down, and finally the platform 5 is leveled.
Then the angle of the first plate body 24 is adjusted according to the depth of 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, and 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 air cylinder 7 and the first plate body 24 rotate, and the angle of the first plate body 24 is fixed by utilizing the self-locking property of the worm wheel 23 and the worm 20. The first air cylinder 7 and the second air cylinder 10 are started, so that the first plate body 24 is obliquely inserted into detection soil, the second plate body 19 is vertically inserted into the detection soil, and after the first plate body 24 and the second plate body 19 are closely contacted, the vehicle body 3 moves to take out the soil in the surrounding area of the first plate body 24 and the second plate body 19 and return to the original point. At this time, the sampling cylinder 13 is started, and the sampling cylinder 13 pushes the soil sampler 18 to be vertically inserted into soil for sampling 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 the soil around that geotome 18 received in the in-process that stretches into soil reduces greatly, and the quick and smooth soil of inserting of the geotome of being convenient for takes a sample, makes the soil sample more smooth and easy, has also improved sample detection's efficiency simultaneously.
According to the invention, after soil on one side of the soil sampler 18 is taken out by using the first plate body 24 and the second plate body 19, the soil sampler 18 is inserted into a target area close to the taken soil by using 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 detection efficiency is improved. On the other hand, the platform 5 is provided with a horizontal inductor 4 at one of the ends of the triangle. After platform 5 takes place to incline, under the action of gravity of quality ball 26, quality ball 26 can be removed to the edge of barrel along passageway 41 by the middle part of barrel, after quality ball 26 is close to hall sensor 27, hall sensor 27 passes through control system control support cylinder 17 work, levels platform 5, finally makes platform 5 level, guarantees that geotome 18 can vertically insert the sample in the soil, prevents that geotome 18 from taking place great slope after, can not obtain the soil sample of each level of ideal degree of depth.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
