The invention specifically works as follows:
connecting the motor 1 with a power supply, connecting the first idle tube 111 and the conveying tube 112 with the motor 1, connecting a plurality of connecting rods 200 with the front part of the conveying tube 112 according to the situation, connecting the front part of the connecting rod 200 connected with the front part of the conveying tube 112 with the rear part of another connecting rod 200, and connecting the front part of the last connecting rod 200 with the feeding tube 311, thereby completing the assembly steps of the device:
then the device is pushed into the sand heap along the required direction, the feeding pipe 311 is known to reach the sampling place by counting the number of the conveying pipes 112, after the feeding pipe 311 reaches the sampling place, the motor 1 is started to drive the first auger 114, the second auger 211 and the third auger 313 to rotate anticlockwise from the front to the back view, the third auger 313 drives the sliding block 314 to rotate, note that the sliding block 314 is positioned in the second idle pipe 316, sliding parts on two sides of the sliding block 314 are contacted with the two second spring plates 317, the sliding block 314 moves backwards, after the sliding part on the left side of the sliding block 314 is contacted with the guide grooves on the inner wall of the first cover plate 312, the sliding block 314 continues to move backwards, meanwhile, the first cover plate 312 is driven to rotate anticlockwise from the front to the back view, the first cover plate 312 is separated from the upper opening of the feeding pipe 311, then the sliding block 314 continues to move backwards along the guide grooves of the conveying pipe 112 and the connecting rod 200, and note that the rotating ring 212 is provided with two notches matched with the sliding parts of the sliding block 314, and the rotating ring 212 does not influence the sliding block 314 to move backwards when the sliding block 314 moves in the connecting rod 200.
When the slider 314 moves into the first idle tube 111, the sliding parts at both sides of the slider 314 lose the supporting force provided by the guide grooves, so that the slider 314 rotates synchronously with the first packing auger 114, and the sliding parts at both sides of the slider 314 press the rear part of the first spring plate 115 forwards, so that the first spring plate 115 deflects without guiding the slider 314 to the spring plate;
meanwhile, the motor 1 drives the ratchet wheel 3110 to rotate anticlockwise when seen from front to back through the third auger 313, the ratchet wheel 3110 drives the rotating block 3111 to rotate through the four pawls 3112, the rotating block 3111 drives the stirring rod 3116 to rotate anticlockwise, it is noted that the collecting system is in the state shown in the upper part of fig. 9, the sliding ring 3115 is located at the rear part of the rotating block 3111 under the action of the elastic force of the three springs 3114, the ball part of the stirring rod 3116 is located outside the guide cover 3118, the stirring rod 3116 can rotate freely along with the rotating seat 3117, when the rotating block 3111 drives the stirring rod 3116 to rotate anticlockwise, the stirring rod 3116 is rotated by sand pile resistance, the stirring rod 3116 is inclined, sand is stirred loose after the stirring rod 3116 is inclined, the sand falls into the opening of the feeding pipe 311 under the action of gravity, and then flows out of the opening of the discharging pipe 113 after the third auger 313, the second auger 211 and the first auger 114; when less sand is around the stirring rod 3116, the stirring rod 3116 continues to expand and deflect outwards under the centrifugal force generated by the rotation of the rotating block 3111, so that the stirring rod 3116 can be tightly attached to the sand pile all the time, and samples can be collected better.
When enough samples are collected, the motor 1 is controlled to rotate reversely, at the moment, the ratchet 3110 rotates clockwise when seen from front to back, the pawl 3112 cannot be driven to rotate, and the rotating block 3111 cannot be driven to rotate, meanwhile, the first auger 114 drives the sliding block 314 to rotate clockwise when seen from front to back, sliding parts on two sides of the sliding block 314 are contacted with the two first spring plates 115, the rear parts of the first spring plates 115 return to the original positions, at the moment, the rear parts of the first spring plates 115 are abutted against the inner wall of the first idle tube 111 and cannot deflect backwards any more, the sliding block 314 is guided, the sliding block 314 moves forwards, the sliding block 314 is separated from the first idle tube 111, and then the sliding block 314 moves forwards along the guide grooves of the conveying tube 112 and the connecting rod 200; in the process of forward movement of the slide block 314, the slide block 314 scrapes off the residual sample in the device and drives the residual sample to move forward together, most of the residual sample is discharged from an upper opening of the feed pipe 311 by the third auger 313, and the rest of the residual sample is transported into a discharge hole formed in the collecting pipe 318, one discharge hole formed in the side part of the collecting pipe 318 is tangential to the rotation direction of the third auger 313, the residual sample is sent into the discharge hole of the collecting pipe 318 when the third auger 313 rotates, and after a large amount of sand is accumulated in the discharge hole, the sand is extruded out of the second cover plate 319 and then returns to a sand pile; when the slider 314 contacts the rear portion of the first cover plate 312, the slider 314 moves forward to drive the first cover plate 312 to rotate clockwise when seen from front to back, so that the first cover plate 312 covers the upper opening of the feed pipe 311; simultaneously, the first cover plate 312 presses the push plate 315 to enable the push plate 315 to move forwards, the front part of the push plate 315 drives the sliding ring 3115 to move forwards to drive the three stirring rods 3116 to move forwards, the axes of the three stirring rods 3116 are separated from the axes of the rotating seat 3117 connected with the three stirring rods 3116, at the moment, the collecting system is in a state shown in the next state diagram of fig. 9, so that the three stirring rods 3116 are clamped by the rotating seat 3117 connected with the three stirring rods 3116, and the vertical direction of the three stirring rods 3116 coincides with the advancing direction of the device; when the slider 314 moves into the second idle tube 316, the sliding parts at two sides of the slider 314 lose the supporting force provided by the guide grooves, so that the slider 314 rotates synchronously with the third auger 313, the sliding parts at two sides of the slider 314 press the front part of the second spring plate 317 backwards, so that the second spring plate 317 is parallel to the rotation direction of the slider 314, and the second spring plate 317 is disabled; under the continuous stirring of the third auger 313 and the squeezing action of the slider 314, the sand remained on the inner wall of the collecting pipe 318 is collected in the discharge hole formed in the collecting pipe 318; at this point self-cleaning within the device is completed.
If the motor 1 is still needed to be sampled deeper, the conveying pipe 112 and the connecting rod 200 connected with the conveying pipe are disconnected, the front part of the connecting rod 200 which needs to be added is connected with the rear part of the connecting rod 200 before, the front part of the conveying pipe 112 is connected with the rear part of the connecting rod 200 which is newly added, and the steps are repeated, so that the second sampling is completed.
When the device is taken out of the sand pile after the sampling work is completed, the first cover plate 312 covers the upper opening of the feeding pipe 311 and abuts against the pushing plate 315, so that the vertical directions of the three stirring rods 3116 are overlapped with the advancing direction of the device, and the resistance is reduced.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
