[0029] The supporting mechanism 4 supports the device to ensure that the soil sampler 1 moves in a longitudinal straight line and will not deviate during the soil sampling process. The height of the pedaling mechanism 5 is adjusted according to the sampling depth. The staff puts their feet on the pedaling mechanism 5 to step on it. Under the action of pressure, the soil sampler 1, the fixed cylinder 2 and the rotating cylinder 3 move downward synchronously. The soil sampler 1 is inserted into the ground to sample soil.

Driven by the linkage component 62, the rotating cylinder 3 rotates, and the rotating cylinder 3 drives the soil sampler 1 to rotate, so that the soil sample inside the soil sampler 1 is separated from the external soil layer, which is convenient for taking out the soil sample. At the same time, the soil sampler 1 rotates after being inserted to a certain depth, which is conducive to inserting the soil sampler 1 deep into the ground.

[0033] The height of the sliding sleeve 51 is adjusted according to the depth of sampling required, and the bottom of the clamping assembly 55 is pressed down to abut against the clamping plate teeth 52. The staff steps on the pedal 53 and steps down to press the clamping assembly 55 to abut against the clamping plate teeth 52, squeezing the clamping plate teeth 52, so that the fixed tube 2 drives the soil sampler 1 to move downward, and the soil sampler 1 is inserted into the ground to take soil samples.

[0035] The rotating sleeve plate 553 abuts against the card plate teeth 52. When the height of the sliding sleeve 51 needs to be adjusted according to the sampling depth, the sliding sleeve 51 slides upward, and the sliding sleeve 51 drives the rotating sleeve plate 553 to move. During the movement of the rotating sleeve plate 553, the top of the rotating sleeve plate 553 abuts against the card plate teeth 52 above it, so that the rotating sleeve plate 553 rotates around the rotating rod 552 to ensure that the sliding sleeve 51 can move longitudinally. After moving to a specified height, the rotating sleeve plate 553 is rotated to a horizontal state under the action of the volute spring 554. At this time, the limiting folding rod 556 abuts against the bottom end of the limiting arc groove 555. During the stepping process, the limiting folding rod 556 limits the rotating sleeve plate 553 to ensure that the rotating sleeve plate 553 cannot rotate during the stepping process. When the sliding sleeve 51 needs to slide downward, the pressing block 558 is pressed, and the pressing block 558 drives the sliding block 551 to move horizontally, and then drives the rotating sleeve plate 553 to move horizontally, so that the rotating sleeve plate 553 is separated from the clamping plate teeth 52, so that the sliding sleeve 51 can slide downward. The setting of the elastic member 1 557 ensures that the rotating sleeve plate 553 can return to the original position after the pressing block 558 is released. The elastic member 1 557 can be a spring, a spring sheet, etc.

[0036] In this embodiment, scale lines are provided on the fixing tube 2 to facilitate height control.

[0037] As an embodiment of the present invention, please refer to Figure 1 , Figures 7 to 11 , the intermittent equiangular rotation assembly 61 comprises: V-grooved cylinder 611, the V-grooved cylinder 611 is provided with two groups, the V-grooved cylinder 611 is provided with a plurality of groups of V-shaped grooves, and one side of the V-shaped groove is a straight line, the two groups of the V-grooved cylinder 611 are arranged longitudinally, and a plurality of groups of V-shaped grooves with a straight groove on one side and an inclined groove on the other side are formed between the two groups of the V-grooved cylinder 611, and the plurality of groups of the V-shaped grooves are internally connected, and the bottom of the V-grooved cylinder 611 is rotatably connected to the supporting arc plate 43; The connecting bevel block 612 is disposed in the V-shaped groove, and its two ends are respectively connected to the two groups of the V-groove cylinders 611. The number of the connecting bevel blocks 612 is equal to the number of the V-shaped grooves. The top of the connecting bevel block 612 is a bevel structure, and the inner side of the bottom of the connecting bevel block 612 is a bevel structure. The second elastic member 613 is located inside the V-groove cylinder 611, and the bottom end is connected to the supporting arc plate 43; The bottom end of the pressing rod 614 is connected to the top end of the second elastic member 613; The telescopic folding rod 615 has a top end connected to the top of the pressing rod 614 and a bottom end connected to the supporting arc plate 43; A connecting rod 616, one end of which is connected to the pressing rod 614; The sliding cartridge 617 is slidably connected to the connecting rod 616 and is movably engaged with the V-shaped slot; The elastic member 3 618 has one end connected to the other end of the connecting rod 616 and the other end connected to the sliding cartridge 617 .

Since the sliding cartridge 617 is located at the top of the connecting inclined block 612, when the sliding cartridge 617 moves downward, the bottom abuts against the top of the connecting inclined block 612. At this time, the connecting inclined block 612 cannot shrink inward to squeeze the elastic member 3 618, and the sliding cartridge 617 can only squeeze the top bevel of the connecting inclined block 612, so that the V-groove cylinder 611 and the connecting inclined block 612 revolve. When the sliding cartridge 617 moves to abut against the inclined groove of the V-groove, it continues to squeeze the inclined groove of the V-groove, so that the V-groove cylinder 611 and the connecting inclined block 612 continue to revolve. When the sliding cartridge 617 moves to the bottom of the V-groove, the pedal 53 cannot Continuing the movement, the staff uses the power of the foot to lift the pedal 53 so that they can continue to step on and press down. During the rising process of the pedal 53, the elastic member 2 613 drives the pressure rod 614 to move upward synchronously, and the telescopic folding rod 615 ensures the longitudinal linear movement of the pressure rod 614. When the pressure rod 614 moves upward, the sliding cartridge 617 is in the V-shaped straight groove. When the sliding cartridge 617 moves to abut against the bottom of the connecting bevel block 612, since the inner side of the bottom of the connecting bevel block 612 is a beveled edge structure, under the reaction force of the elastic member 2 613, the sliding cartridge 617 slides horizontally along the connecting rod 616 during the upward movement, squeezing the elastic member 3 618. When the sliding cartridge 617 moves to the top of the connecting bevel block 612 under the action of the elastic member 2 613, the sliding cartridge 617 rebounds to its original position under the reaction force of the elastic member 3 618 for subsequent movement. The second elastic member 613 and the third elastic member 618 can both be springs, spring sheets, etc.

[0045] After the sampling is completed, the staff pulls out the soil sampler 1 and presses the sliding pressure rod 7 downwards, and the sliding pressure rod 7 drives the bulldozer 8 to move, and the bulldozer 8 pushes the soil sample inside the soil sampler 1 out.

[0046] A method for using a soil sampling device for farmland protection includes the above-mentioned soil sampling device for farmland protection, and further includes the following steps: S1. Place the supporting arc plate 43 on the ground. The staff adjusts the height of the sliding sleeve 51 according to the depth of the soil sample to be collected. The rotating sleeve 553 abuts against the clamping plate teeth 52. The limiting arc groove 555 limits the limiting folding rod 556. S2. The staff member steps on the pedal 53 and steps down hard.

The supporting arc plate 43, the sliding folding rod 41 and the connecting cylinder 42 prevent the earth picker 1 from tilting, and ensure that the earth picker 1 is inserted into the ground in a straight line; S3. When the pedal 53 moves downward and contacts the pressing rod 614, the pedal 53 is continued to be stepped on, and the pedal 53 drives the pressing rod 614 to move downward, and the pressing rod 614 drives the sliding cartridge 617 to move downward, and the sliding cartridge 617 moves in the V-shaped slot to squeeze it, so that the V-groove cylinder 611 rotates, and the V-groove cylinder 611 drives the gear 1 621 to rotate, and the gear 1 621 drives the gear ring 1 622 to rotate, and the gear ring 1 622 drives the gear 2 624 to rotate, and the gear 2 624 drives the vertical cylinder 6251 and the sliding straight rod 6252 to rotate synchronously, and the sliding straight rod 6252 drives the gear 3 626 to rotate, and the gear 3 626 drives the gear ring 2 627 to rotate, and the gear ring 2 627 drives the rotating cylinder 3 to rotate, thereby driving the soil sampler 1 to rotate, cutting the soil sample, so that the soil sample inside the soil sampler 1 is separated from the soil sample outside; S4. After the sampling is completed, the worker's foot leaves the pedal 53, pulls out the soil sampler 1, and presses the sliding pressure rod 7 downward. The sliding pressure rod 7 drives the bulldozer 8 to move, and the bulldozer 8 pushes the soil sample inside the soil sampler 1, and the sampling is completed.

[0047] The working principle of the present invention is as follows: in the initial state, the sliding cartridge 617 is located at the top of the V-shaped slot and at the top of the connecting bevel block 612; The supporting arc plate 43 is placed on the ground. The staff adjusts the height of the sliding sleeve 51 according to the depth of the soil sample to be collected. The staff steps on the pedal 53 and steps down hard. The pedal 53 drives the fixed cylinder 2 to move downward, and then drives the soil extractor 1 to move downward, so that the soil extractor 1 is inserted into the ground to extract soil. The supporting arc plate 43, the sliding folding rod 41 and the connecting cylinder 42 prevent the soil extractor 1 from tilting, ensuring that the soil extractor 1 is inserted into the ground in a straight line. As the soil extractor 1 is continuously inserted into the ground, its resistance gradually increases. When the pedal 53 moves downward until it abuts against the pressure rod 614, the pressure rod 614 is squeezed, so that the sliding cartridge 617 moves downward. At the same time, the elastic member 2 613 undergoes elastic deformation. Since the sliding cartridge 617 is located at the top of the connecting bevel block 612, when the sliding cartridge 617 moves downward, the bottom abuts against the top of the connecting bevel block 612. At this time, the connecting bevel block 612 cannot shrink inward to squeeze the elastic member 3 618, and the sliding cartridge 617 can only squeeze the top bevel of the connecting bevel block 612, so that the V-groove cylinder 611 and the connecting bevel block 612 revolve. When the sliding cartridge 617 moves to the V-groove cylinder 611 and the connecting bevel block 612 revolve, When the slot bevels are in contact, the V-shaped slot bevels are continuously squeezed, so that the V-groove cylinder 611 and the connecting bevel block 612 continue to revolve, the V-groove cylinder 611 drives the gear 1 621 to rotate, the gear 1 621 drives the gear ring 1 622 to rotate, the gear ring 1 622 drives the gear 2 624 to rotate, the gear 2 624 drives the vertical cylinder 6251 and the sliding straight rod 6252 to rotate, and then drives the gear 3 626 to rotate, the gear 3 626 drives the gear ring 2 627 to rotate, the gear ring 2 627 drives the rotating cylinder 3 to rotate, and then drives the soil extractor 1 to rotate, so that the soil extractor 1 continues to be inserted into the ground. At the same time, the soil extractor 1 rotates to separate the soil sample inside it from the external soil layer, so that the soil sample is easy to take out; When the sliding cartridge 617 moves to the bottom of the V-shaped slot, the pedal 53 cannot move further, and the staff uses the power of the foot to lift the pedal 53 so that they can continue to step on it. During the ascending process of the pedal 53, the elastic member 613 drives the pressure rod 614 to move upward synchronously, and the telescopic folding rod 615 ensures the longitudinal linear movement of the pressure rod 614. When the pressure rod 614 moves upward, the sliding cartridge 617 is in the straight groove of the V-shaped slot. When the sliding cartridge 617 moves to the bottom of the V-shaped slot, the staff can step on the pedal 53 to move downward. When the bottom of the connecting bevel block 612 is in contact, since the inner side of the bottom of the connecting bevel block 612 is a bevel structure, under the reaction force of the second elastic member 613, the sliding cartridge 617 slides laterally along the connecting rod 616 during the upward movement, and squeezes the third elastic member 618. When the sliding cartridge 617 moves to the top of the connecting bevel block 612 under the action of the second elastic member 613, the sliding cartridge 617 rebounds to the original position under the reaction force of the third elastic member 618, so as to perform subsequent movement; After the sampling is completed, the staff pulls out the soil sampler 1 and presses the sliding pressure rod 7 downwards, and the sliding pressure rod 7 drives the bulldozer 8 to move, and the bulldozer 8 pushes the soil sample inside the soil sampler 1 out.
