[0021] The following will further describe the technical solution of the utility model in conjunction with the drawings of the embodiments of the utility model, and the utility model is not limited to the following specific implementation methods. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] like Figures 1 to 3 As shown, a multi-channel soil mechanical composition measuring device includes: a main body 100, a measuring mechanism and a placement rack 300; a plurality of experimental channels are arranged on one side of the main body 100, each of the experimental channels includes a positioning buckle 410 and a sampling dish holder 420, each of the positioning buckles 410 is arranged at intervals with a sampling dish holder 420, and the placement rack 300 is movably arranged below each of the positioning buckles 410; the measuring mechanism is slidably arranged on one side of the main body 100, and the measuring mechanism is movably located above any of the experimental channels. That is, when conducting an experiment, a sampling dish will be placed on the sampling dish holder 420.

[0023] In one embodiment, the number of the experimental channels is six. That is to say, the number of experimental channels can be specifically set according to specific needs, for example, the number of the experimental channels is four, for example, the number of the experimental channels is five, or the number of the experimental channels is seven, that is to say, the number of experimental channels has a variety of options, which are selected according to different experimental situations, and the description is not cumbersome in this embodiment. It is worth mentioning that, taking the number of experimental channels set as six as an example, the six experimental channels are named "Channel 1, Channel 2, Channel 3, Channel 4, Channel 5 and Channel 6" respectively, and then the experiment can be started. Each of the experimental channels also includes an infrared sensing probe, and each of the infrared sensing probes is arranged on one of the positioning buckles 410. A slide rail 510 is arranged on the main body 100, a slider 520 is slidably arranged on the slide rail 510, a mounting plate 530 is arranged on the slider 520, and the measuring mechanism is arranged on the mounting plate 530. It is worth mentioning that the slider 520 is driven to slide on the slide rail 510 by a driver, that is, the slider 520 can be driven by a power source driven by the prior art, so that the slider 520 can slide on the slide rail 510, for example, the driver is a driving cylinder, and can also be other drivers, which are not described in detail in this embodiment. A fixed support shaft 540 is arranged on the mounting plate 530, and the measuring mechanism includes a column 210, a syringe assembly, a cleaning peristaltic pump 230 and a sampling gun head 240, the column 210 is rotatably arranged on the fixed support shaft 540, the syringe assembly and the cleaning peristaltic pump 230 are arranged on the column 210, and the sampling gun head 240 is slidably arranged on the column 210. Further, a driving motor 610 and a screw rod 620 are arranged on the column 210, and the driving motor 610 is used to drive the screw rod 620, and the sampling gun head 240 is slidably arranged on the screw rod 620. The sampling gun head 240 is provided with an inner cavity, and the inner cavity is provided with a distance detector 241 and a glass sampling gun 242. The syringe assembly and the cleaning peristaltic pump 230 are respectively connected to the glass sampling gun 242 through a silicone hose 700. It is worth mentioning that the other end of the cleaning peristaltic pump 230 is connected to a cleaning bottle 900 through another silicone hose 800. Further, the distance detector 241 is an ultrasonic distance detector 241.

[0024] In the above embodiment, the syringe assembly includes an electric push rod 221 and a glass syringe 222 . The electric push rod 221 is used to push and pull the glass syringe 222 . The glass syringe 222 is connected to the glass sampling gun 242 through the silicone hose 700 .

[0025] In one embodiment, a spring pin 211 and a flat pad 212 are provided on the column 210 , the spring pin 211 is movably connected to the mounting plate 530 , and the flat pad 212 is movably abutted against the host body 100 .

[0026] The above embodiment also includes a control system, which is a PLC control system, and the control system has a control tablet 101. The driver, each of the infrared sensing probes, the measuring mechanism and the drive motor 610 are all electrically connected to the control system. In other words, the entire multi-channel soil mechanical composition measuring equipment can be controlled directly using the control tablet 101.

[0027] When using this multi-channel soil mechanical composition determination equipment for experiments, the entire workflow is divided into three working sampling stages. In the first stage, the staff first places the sample in channel 1 to channel 6, then stirs the sample in channel 1, clicks the "Start" button of channel 1 on the control tablet 101, and enters a 60-second countdown, then stirs the sample in channel 2, and after stirring, clicks the "Start" button of channel 2 on the tablet, and channel 2 enters a 60-second countdown. The operations of channels 3 to 6 are the same.

[0028] That is to say, after the 60-second countdown of channel 1 is over, the sampling gun head 240 descends, and the sample liquid level is determined by the ultrasonic distance detector 241. The sampling gun head 240 descends to 10 cm above the liquid level and starts to suck liquid for sampling. After sampling, the sampling gun head 240 rises and then moves to the top of the sampling dish of channel 1 to release the sample. The cleaning peristaltic pump 230 draws clean water in the cleaning bottle 900 to clean the soil particles remaining on the inner wall of the glass sampling gun 242. The cleaning liquid is collected in the same sampling dish. After one sampling is completed, the control tablet 101 will give a voice prompt to take the sample liquid in time, and then use the washing bottle to rinse and remove the soil particles on the outer wall of the glass sampling gun 242, wait for the countdown of channel 2 to end, repeat the above operation, and finally complete the sampling of channel 6. The sampling gun head 240 returns to the origin and waits for the second stage of sampling.

[0029] Furthermore, the sampling time of the second stage starts 10 minutes after the individual sampling of each channel in the first stage is completed, and then the same operation as the sampling process of the first stage is repeated.

[0030] The sampling time for the third stage starts 6 to 8 hours after the individual sampling of each channel in the second stage is completed, and then the same operation as the sampling process in the first stage is repeated.

[0031] Except for the first stage, which requires manual clicking of the "start" button, all other operations can be completed automatically by the experimental device. Specifically, after each stage is completed, the sampling dish is removed and replaced with a new sampling dish.

[0032] The "Start" button on the tablet will light up only after the sedimentation tube buckle of each channel and the infrared sensor probe behind the sampling dish holder 420 detect that the sample and the sampling dish are in place. In other words, if the sample and the sampling dish are not detected in place, the "Start" button on the corresponding channel on the control tablet 101 cannot be clicked.

[0033] It is worth mentioning that the staff can use it according to specific needs, that is, there is no need to fill all six channels with samples. According to the actual situation, 1 to 6 samples can be placed, and the entire multi-channel soil mechanical composition determination equipment will work normally, and will automatically enter the next stage of sampling after the countdown ends.

[0034] It is worth mentioning that since the main body 100 and the placement rack 300 are arranged at intervals, that is, the placement rack 300 is only located on one side of the main body 100, therefore, in each measurement experiment, since the standing time in the third stage is relatively long, the main body 100 can be moved to another batch of samples during this period to complete the sampling of this batch of samples, which can save equipment costs and complete the sampling of multiple batches of samples at the same time. Therefore, moving the main body 100 will not cause the previous batch of samples to move and affect the standing effect, and therefore will not affect the data accuracy of the entire experiment.

[0035] In one embodiment, by providing a spring pin 211, when the column 210 is vertically above the mounting plate 530, the spring pin 211 will be stuck on the mounting plate 530, thereby fixing the column 210. When the device is not needed or transported, the column 210 can be rotated 90 degrees and laid flat on the host body 100. At this time, the flat pad 212 abuts against one side of the host body 100 and provides good support for the entire column 210.

[0036] In summary, the above-mentioned implementation modes are not limitative implementation modes of the present invention, and any modification or equivalent deformation made by technicians in this field on the basis of the essential content of the present invention is within the technical scope of the present invention.
