[0047] Working principle:

[0048] In the actual design process of the present invention, in order to avoid the following defects existing in the prior art:

[0049] "When the sampling part of the soil detection device in the prior art is performing sampling action, the installation position of the drill bit in the external sleeve is fixed, which will result in the drill bit being unable to be adaptively adjusted during the actual drilling process, easily causing problems such as the drill bit being stuck and the sampling distance not matching, ultimately resulting in the soil sample being unable to smoothly enter the interior of the sampling tube." Targeted structures such as a vibrating knife sampling component 2, a positioning component 3 and a coarse distance adjustment component 4 are proposed.

[0050] When in use, the main frame of the device is set above the soil portion where sampling is required, and four foot pads are respectively arranged around the sampling point to achieve the effect of auxiliary positioning.

[0051] Start the bidirectional motor 11, and the bidirectional motor 11 drives the main shaft 8 on its output end to rotate. During the rotation of the main shaft 8, the drill bit 1 at the end drives the soil at the sampling site, and the soil at the sampling site is lifted up and enters the interior of the bushing 6. The auger 9 synchronously installed on the main shaft 8 can achieve the soil transmission effect. The soil at the sampling site is transmitted to the surface of the detection rod 14 on one side of the soil detector 13 through the auger 9 to realize the detection of soil elements, components, pH and other parameters. After the detection is completed, start the bidirectional motor 11 in reverse, and the bidirectional motor 11 quickly discharges the retained soil inside through the auger 9 and the drill bit 1. This design can achieve the effects of rapid sampling, detection and sample discharge, and increase the use efficiency of the device.

[0052] Use of the vibrating knife sampling component 2:

[0053] The optimization of this component over the traditional sampling component is that it can control the drill bit 1 and the auger 9 on the main shaft 8 to move up and down through the electric cylinder 12. When the drill bit 1 changes its position inside the bushing 6, the sampling height can be changed in real time, which is convenient for adapting to soils of different terrains. In addition, we have installed the bracket 16 and the suspension 17 on the main shaft 8 through the bearing seat 15, and the roller 19 installed inside the suspension 17 can roll up and down inside the external sleeve 5; the main function of this auxiliary structure is to achieve positioning during the up and down movement of the main shaft 8. In addition, we directly connect the spring 21 between the support rod 20 and the sleeve 5. The spring 21 plays a buffering and positioning effect during the lifting and lowering of the main shaft 8. While achieving a certain degree of vibration, it avoids the problem of the main shaft 8 being too long and then causing the auger 9 to hit. Secondly, the spring 21 can modulate the displacement of the output end of the electric cylinder 12 to avoid the problem of sudden large-distance telescopic expansion.

[0054] Positioning component 3:

[0055] The main function of the positioning assembly 3 is to realize the vertical height positioning of the main frame to avoid the problem of positioning failure due to vibration during the sampling process. The sliding sleeve 23 adjusts the installation height on the surface of the guide rod 24, and then the bolt 30 in the screw cover 29 realizes the locking positioning effect.

[0056] Coarse adjustment component 4:

[0057] The coarse distance adjustment component 4 is mainly used in conjunction with the sampling component to achieve a large distance movement effect. In order to achieve a stable height adjustment effect, a guide block 31 is set on the surface of the frame plate 22, and the interior of the guide block 31 is driven by a screw rod 32 to achieve a height adjustment effect. The screw rod 32 is driven by the drive 34 to rotate, and then the entire sampling frame is lifted or lowered by screw transmission.

[0058] The present invention provides a vibrating knife sampling component 2, so that the drill and auger 9 of the device can achieve the effect of lifting elastic vibration during the sampling process and after the sampling is completed, so that the excess mud and sand attached to the surface of the cutter and the auger 9 can be removed in time to avoid the problem of blockage. In addition, the head drill can adapt to different sampling conditions during the extension and retraction process, so as to avoid the problem of difficulty in drilling soil or failure of suspended sampling. Through the coarse adjustment component 4, the whole sampling component can achieve the overall height adjustment effect, and its main purpose is to achieve a large-distance displacement adjustment effect, and cooperate with the fine adjustment effect of the vibrating knife component 801 to achieve an accurate position positioning effect. Through the positioning component 3, the device can achieve position accuracy during the erection and height adjustment process, avoiding the problem of position deviation after the positioning is completed, and then causing the problem of positioning failure. Through the implantable soil detector 13, the detection rod 14 and the bidirectional motor 11, the effects of real-time sampling, real-time detection and real-time sample arrangement can be achieved. This operation mode greatly reduces the sampling time interval and increases the efficiency of sampling and detection of the device. By setting up multiple frame components and setting up a cross-set structure between the frame and the bracket, the positioning center of gravity of the device always falls on the part below the frame, making the device more stable, thereby avoiding the problem of rollover during soil drilling and sampling. By setting up the structure of the integrated vibration knife component, that is, the built-in vibration knife structure, the positioning buffer component can be installed inside the sleeve without affecting the external structure of the traditional sampling component, so that the appearance structure of the device and the traditional sampling component is not much different, making replacement and maintenance more convenient.
