Example 1

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model discloses a multi-level soil sample collection device for land planning. The handle 3 is fixedly installed on the top, the drive sleeve 6 is installed vertically in the center and fixed axially, the support frame 4 is fixedly installed on the left side of the upper surface, the round hole of the support frame 4 is coaxial with the drive sleeve 6, and the drive sleeve 6 and the support frame 4 are fixedly installed with a two-way motor 2, the rotating shaft of the two-way motor 2 goes deep into the inside of the box 1, and its end is fixedly connected to the driving wheel 8, and the drive sleeve 6 is internally threaded to connect the drill pipe 5. The outer intermediate position is fixedly connected with the driven wheel 9, the drill rod 5 passes through the round hole of the support frame 4 and the bottom end is fixedly connected to the drill bit 7 by bolts, and the battery 10 is fixedly placed on the inner bottom of the box body 1, so The battery 10 is used to drive the bidirectional motor 2 to rotate.

The drill rod 5 includes an upper connecting portion 501 at the upper end, each of which has a countersunk screw hole 502 on the left and right sides of the upper connecting portion 501, and has a collection chamber front cavity 503 in the center, and a baffle plate 504, a baffle plate A chute 507, the baffle plate 504 can slide in the baffle plate chute 507 and block the front opening of the collection chamber front cavity 503, and the right side of the outer surface of the baffle plate 504 is provided with a raised stopper 505, a spring shaft 508 is fixedly installed on the left side of the front opening of the collection chamber front cavity 503 at the rear of the baffle plate 504, and a scraper 506 is set on the spring shaft 508, which can wind around the spring shaft 508 Rotate and lift at an angle of about 30 degrees. The lower end of the drill rod 5 is the lower connection part 509. The middle part of the lower connection part 509 is provided with a bolt hole 510 and a rear chamber 511 of the collection chamber. The thread end end of the lower part of the drill rod 5 A baffle cavity 513 is fixedly connected to the upper end of the lower connecting portion 509, and a circular baffle 512 is slidably installed inside the baffle cavity 513, and the upper connecting portion 501 cooperates with the lower connecting portion 509 of another drill pipe 5 connection, the connection method is that the countersunk screw holes 502 are aligned with the screw holes 510 and connected by bolts, and after the two drill rods 5 are connected, the collection chamber front chamber 503 and the collection chamber rear chamber 511 are merged into one Complete collection room, just can have one more soil sample collection room after inserting a drill pipe 5, the length of drill pipe 5 can be different lengths according to need, can adapt to the needs of collecting soil samples at different depths.
