When the upper cover 37 continues to move backward, it can squeeze the first spring 40 and make the detection box 38 fully open. At this time, the lower port can be opened, and the material in the quantitative cylinder 14 can fall into the detection box 38. Through the cooperation of the set trapezoidal plate 39 and the driving plate 16, when loading, the upper cover 37 can be moved backward for a distance to prevent the material from falling onto the upper cover 37. When the driving plate 16 continues to move to the right, it can slowly disengage from the trapezoidal plate 39. After completely disengaging, the trapezoidal plate 39 and the upper cover 37 can be reset to the initial state under the elastic force of the first spring 40, that is, the detection box 38 is closed.

[0045] The front end surface of the soil detector 36 is fixedly connected to the first tension spring 35, the bottom inner wall of the box body 1 is provided with a lower cover 33, the upper end surface of the lower cover 33 is fixedly connected to a plurality of tension spring seats 34 that are evenly distributed and matched with the first tension spring 35, and the front end of the lower cover 33 is fixedly connected to the first handle 31.

[0046] like Figure 9-10As shown, the lower cover 33 can be slidably connected to the lower end surface of the soil detector 36, and the interior of the detection box 38 is hollow. When the lower cover 33 is in the rearmost position, the lower end of the detection box 38 can be sealed. When the lower cover 33 moves forward, the lower end of the detection box 38 can be opened. At this time, the soil in the detection box 38 can fall into the outside world, that is, outside the box body 1 under the action of gravity; the front ends of the first tension springs 35 are respectively fixed to the spring seats 41, and the rear ends of the first tension springs 35 are respectively fixed to the soil detector 36. The first tension springs 35 always have a backward pulling force on the spring seats 41 and the lower cover 33, so that the lower end of the detection box 38 is in a normal state. In the sealed state, when centralized unloading is required, by pulling the first handle 31 forward, the lower cover 33 can be driven to move forward, that is, the materials in the detection box 38 fall into the outside under the action of gravity, and a connecting plate 32 is fixedly connected to the front end surface of the lower cover 33. The connecting plate 32 passes through the box body 1 and is slidably connected to the inner wall of the box body 1. The first handle 31 is fixedly connected to the front end surface of the connecting plate 32, which is equivalent to the first handle 31 being fixedly connected to the front end of the lower cover 33. The first handle 31 and the lower cover 33 can be connected by the set connecting plate 32, and it is convenient to drive the first handle 31 and the lower cover 33 to move, that is, to control the detection box 38 to be opened or closed.

[0047] The inner wall at the bottom end of the box body 1 is slidably connected with a connecting bottom plate 53, and the soil detectors 36 are respectively fixed to the upper end surface of the connecting bottom plate 53. The right end of the connecting bottom plate 53 is provided with a ball pin 43 that can move left and right.

[0048] like Fig.10 or Figure 13-14 As shown, the connecting bottom plate 53 can be slidably connected to the inner wall of the bottom end of the box body 1, and the soil detector 36 is fixedly installed on the connecting bottom plate 53. When the connecting bottom plate 53 moves left and right, it can synchronously drive multiple soil detectors 36 to move synchronously; a connecting rod 42 is fixedly connected to the right end surface of the connecting bottom plate 53, and a ball pin 43 is fixedly connected to the connecting rod 42, which is equivalent to the ball pin 43 being fixedly connected to the right end of the connecting bottom plate 53. When the ball pin 43 reciprocates and oscillates left and right, it can drive the connecting bottom plate 53 to move left and right, that is, the soil detector 36 and the detection box 38 can be reciprocated and oscillated left and right. When the detection box 38 is filled with cleaning liquid, the detection box 38 can be cleaned. The cleaning liquid in the test box 38 oscillates, and the inner wall of the test box 38 is cleaned under the action of inertia, thereby regularly cleaning the test box 38; when the test box 38 needs to be cleaned, by adding cleaning liquid into the soil sample storage bucket 24, when the quantitative cylinder 14 moves, the cleaning liquid can also be quantitatively poured into the corresponding test box 38, and then the ball pin 43 is reciprocated and oscillated left and right, so as to clean the test box 38; when the quantitative cylinder 14 moves left and right, it will also oscillate left and right with a small amplitude. When the quantitative cylinder 14 oscillates left and right with a small amplitude, the cleaning liquid can also rinse the quantitative cylinder 14 and the inner wall of the soil sample storage bucket.

[0049] A rotatable driving shaft 52 is provided on one side of the box body 1, and a second cam 49 cooperating with the ball pin 43 is hinged on the left side of the outer surface of the driving shaft 52, and a first cam 47 that can move left and right is provided on the right side of the outer surface of the driving shaft 52, and a short connecting rod 48 is provided between the first cam 47 and the second cam 49.

[0050] like Figure 13-14 As shown, the second cam 49 is hinged on the outer surface of the drive shaft 52. When the drive shaft 52 rotates, it can drive the second cam 49 to rotate, and the second cam 49 can also deflect and swing on the drive shaft 52. The drive shaft 52 is rotatably connected to the inner wall of one side of the box body 1. The first cam 47 and the drive shaft 52 are splined. The first cam 47 can slide left and right on the outer surface of the drive shaft 52, and when the drive shaft 52 rotates, it can drive the first cam 47 to rotate. The installation and shape of the short connecting rod 48, the second cam 49, and the ball pin 43 are as shown in FIG. Fig.14 As shown, one end of the short connecting rod 48 is hinged on the first cam 47, and the other end of the short connecting rod 48 is hinged on the second cam 49. When the first cam 47 moves left and right, the second cam 49 can be driven to swing and deflect through the hinge of the short connecting rod 48 and the second cam 49. After the second cam 49 deflects, when the driving shaft 52 rotates, the second cam 49 can be driven to deflect and rotate. When the second cam 49 deflects and rotates, it will drive the ball pin 43 to move back and forth left and right through the engagement with the ball pin 43; when the second cam 49 is in a vertical state, that is, the rotation of the second cam 49 will not drive the ball pin 43 to move, that is, the corresponding connecting base plate 53 and the soil detector 36 are in a stationary state.

[0051] A small threaded rod 45 is threadedly connected to the inner wall of the right end of the box body 1, and the left end of the outer surface of the small threaded rod 45 is rotatably connected to an arc seat 46 that cooperates with the first concave wheel 47. A driven pulley 50 is also fixedly connected to the outer surface of the driving shaft 52, and a driving pulley 51 is fixedly connected to the right end of the outer surface of the long threaded rod 7. The driving pulley 51 is connected to the driven pulley 50 through a belt.

[0052] like Figure 13-14As shown, a second handle 44 is fixedly connected to the right end surface of the small threaded rod 45. The function of the second handle 44 is to facilitate driving the small threaded rod 45 to rotate. Through the threaded connection between the small threaded rod 45 and the box body 1, when the small threaded rod 45 rotates, the small threaded rod 45 and the arc seat 46 can move left or right. The arc seat 46 is sleeved on the inner wall of the first concave wheel 47. Through the connection between the arc seat 46 and the first concave wheel 47, when the arc seat 46 moves left and right, it can drive the first concave wheel 47 to move left and right. When the first concave wheel 47 moves left and right, it can drive the second concave wheel 49 to deflect, and the first concave wheel 47 does not affect the connection with the arc seat 46 when it rotates, and has a self-locking function under the threaded connection between the small threaded rod 45 and the box body 1, that is, when the small threaded rod 45 does not rotate, the corresponding position of the first concave wheel 47 is fixed, that is, the deflection angle of the second concave wheel 49 is fixed; through the active pulley 51 and the driven pulley 50, when the long threaded rod 7 rotates, it can drive the active pulley 51 and the driven pulley 50. The driven pulley 50 and the driving shaft 52 rotate synchronously; when the soil detector 36 detects the soil, the small threaded rod 45 is rotated by driving the second handle 44 to adjust the deflection angle of the second concave wheel 49, and the second concave wheel 49 is adjusted to be in a vertical state. At this time, the ball pin 43 will not move and the soil detector 36 can work stably. When it is necessary to clean the detection box 38, by adding cleaning liquid into the soil sample storage bucket 24, the deflection of the second concave wheel 49 is adjusted by driving the second handle 44, and when the long threaded rod 7 rotates, the quantitative cylinder 14 can be driven to move to pour the cleaning liquid into the detection box 38. When the second concave wheel 49 rotates with the long threaded rod 7, it can rotate and drive the ball pin 43 to oscillate back and forth, that is, the corresponding soil detector 36 and the detection box 38 oscillate back and forth. At this time, the cleaning liquid can rinse the inner wall of the detection box 38, and the amplitude of the reciprocating left and right movement of the detection box 38 can be adjusted, and adaptive adjustment is performed according to the degree of dirtiness of the detection box 38.

[0053] When the present invention is in use, when the upper port is opened and the lower port is closed, the soil in the soil sample storage bucket 24 can fall into the quantitative cylinder 14 under the action of gravity, and when the upper port is closed and the lower port is opened, the soil in the quantitative cylinder 14 can fall into the specified position. Since the volume of the quantitative cylinder 14 is fixed, the amount of soil discharged each time is a fixed value; that is, when the quantitative cylinder 14 moves to the specified position to the right, that is, when the quantitative cylinder 14 moves to the upper end of the corresponding detection box 38, the lower port can be opened and the upper port can be closed, and the soil in the quantitative cylinder 14 falls into the corresponding detection box 38, so that quantitative material is put into each detection box 38, the detection accuracy is improved, the waste of soil samples is reduced, etc.; when the quantitative cylinder 14 continues to move to the right away from the detection box 38, the lower port can be closed and the upper port can be opened, and the material in the soil sample storage bucket 24 falls into the quantitative cylinder 14, so that the next detection box 38 can be quantitatively put into the soil sample.
