[0024] The crushing and feeding mechanism 4 includes a main shaft 41 fixedly connected to the output shaft of the motor 3, a spiral feeding piece 42 fixedly connected to one end of the side of the main shaft 41, a scraper 43 fixedly connected to one end of the side of the main shaft 41, and a soil crushing drill bit 44 fixedly connected to the lower end of the main shaft 41.

[0025] The above scheme is adopted: the soil can be crushed by the soil crushing drill bit 44, so as to avoid some hard soils that are difficult to extract samples, and then the crushed soil is transported upward by the spiral feeding piece 42 and sent to the collecting plate 2.

[0026] The sampling mechanism 5 includes a sampling box 51 fixedly connected to one end below the collecting tray 2, a waste collection box 52 fixedly connected to one end of the side of the sampling box 51, a fixing mechanism 53 is provided at one end of the side of the sampling box 51, a vibration motor 54 is provided at one end of the side of the sampling box 51, a filter screen 55 is embedded at one end inside the sampling box 51, and a sampling tube 56 is provided at one end below the sampling box 51.

[0027] The above scheme is adopted: the soil on the collecting tray 2 is scraped by the scraper 43 to the sampling mechanism 5 below, and the soil falls into the sampling tube 56 below through the sampling box 51. Some garbage and large pieces of gravel will remain on the filter screen 55. The filter screen 55 is tilted toward the waste collection box 52. The garbage and gravel on the filter screen 55 are shaken by the vibration motor 54 on the side to fall into the waste collection box 52 on the side for collection and treatment.

[0028] The fixing mechanism 53 includes a rotating block 531 and a rotating rod 532 fixedly connected to one end of the side of the sampling box 51. One end of the side of the rotating block 531 is rotatably connected to a connecting block 533, one end below the connecting block 533 is fixedly connected to a limiting block 534, and one end of the side of the rotating rod 532 is rotatably connected to a locking block 535.

[0029] The above solution is adopted: by rotating the locking block 535 so that the locking block 535 is aligned with the groove provided on the side of the connecting block 533, the limit on the connecting block 533 is cancelled, and the connecting block 533 can be rotated at this time, and then the sampling tube 56 can be taken out.

[0030] The feed barrel 1 comprises a feed barrel body 11 fixedly connected to one end below the collecting plate 2 , and a drill ring 12 is fixedly connected to one end below the feed barrel body 11 .

[0033] The working principle of the utility model is as follows: first, the device is fixed on the land where samples need to be extracted through the mounting seat body 61 and the limit pile 62, and then the crushing and feeding mechanism 4 is driven to rotate by the motor 3, and the land can be crushed by the crushing drill bit 44, so that some hard soil is not easy to extract samples, and then the crushed soil is transported upward by the spiral feeding piece 42 to the collecting plate body 21, and then the soil on the collecting plate body 21 is scraped into the discharge port 22 by the scraper 43 so that it falls to the sampler below. In structure 5, soil falls into the sampling tube 56 below through the sampling box 51, and some garbage and large pieces of gravel will remain on the filter screen 55. The filter screen 55 is tilted toward the waste collection box 52. The garbage and gravel on the filter screen 55 are shaken by the vibration motor 54 on the side to fall into the waste collection box 52 on the side for collection and treatment. By rotating the locking block 535 to align the locking block 535 with the groove opened on the side of the connecting block 533, the limit on the connecting block 533 is cancelled. At this time, the connecting block 533 can be rotated, and then the sampling tube 56 can be taken out.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
