[0002] Soil pollution monitoring is an important part of environmental monitoring, which aims to understand soil environmental quality, control and predict soil pollution, protect human health and maintain ecological balance. Traditional soil pollution detection methods require manual collection of soil samples, which is inefficient and time-consuming. In addition, some soil pollution monitoring devices are not easy to move, which adds a lot of labor to the staff.

[0003] According to a publicly disclosed farmland soil pollution monitoring device (announcement number: CN218271427U), the above application includes a chassis, which is composed of a box body, a first handle fixedly connected is arranged on one side of the box body near one end, a groove is opened on the other side, and a slidably connected detection plate is arranged on the groove, the detection plate is located inside the box body, and a second handle fixedly connected is arranged on one side of the detection plate, a sampling hole is opened on the surface of one side of the box body, and an inner cavity is arranged inside the box body.

[0004] However, in actual use, the above-mentioned soil pollution monitoring device needs to replace the detection plate each time after testing a piece of soil. Replacing the detection plate requires additional time and operation steps, especially in large-scale soil sampling and testing tasks. This increases the time consumption of the entire soil sampling and testing process and affects work efficiency. In view of this, we propose a farmland soil pollution monitoring device.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a farmland soil pollution monitoring device, including a chassis 1, a universal wheel 2 is fixedly connected to the bottom end face of the chassis 1, an electric push rod 3 is fixedly connected to the inner wall of the chassis 1, and the end of the electric push rod 3 away from the inner wall of the chassis 1 is fixedly connected to the sampling device 4, a limit rod 6 is fixedly connected to the inner wall of the chassis 1, and the limit rod 6 abuts against the sampling device 4, a through hole 5 is opened on the inner bottom surface of the chassis 1, and a detection component is arranged on the inner bottom surface of the chassis 1, and the detection component includes a rotating shaft 7, a mounting sleeve 8, a detection box 9, a cover plate 10, a connecting rod 11, a toggle rod 12, an arc-shaped telescopic rod 13, a spring 14, a hemisphere 15, and a groove 16.

[0026] In one embodiment of the utility model, the inner bottom surface of the chassis 1 is fixedly connected with a rotating shaft 7, the side wall of the rotating shaft 7 is sleeved with a mounting sleeve 8, the mounting sleeve 8 is sleeved with a detection box 9, the number of detection boxes 9 is arranged in a plurality of groups, and the plurality of detection boxes 9 are arranged around the rotating shaft 7 at equal intervals. By providing a plurality of groups of detection boxes 9, the number of soil samples detected at one time is increased, and the detection efficiency is improved. A groove 16 is provided at the bottom of the detection box 9, the inner bottom surface of the chassis 1 is fixedly connected with a hemisphere 15, the hemisphere 15 is snap-fitted with the groove 16, the rotating shaft 7 is sleeved with a cover plate 10, the bottom end surface of the cover plate 10 is abutted with the top end surface of the detection box 9, and the sampling device 4 The side wall of the toggle rod 12 is fixedly connected with a connecting rod 11, and the end of the connecting rod 11 away from the sampling device 4 is hinged with a toggle rod 12, the toggle rod 12 abuts against the detection box 9, and the toggle rod 12 moves in a direction away from the through hole 5, thereby pushing the detection box 9 to rotate around the rotating shaft 7, the side wall of the toggle rod 12 abuts against the connecting rod 11, and the side wall of the toggle rod 12 is fixedly connected with an arc-shaped telescopic rod 13, and the end of the arc-shaped telescopic rod 13 away from the toggle rod 12 is fixedly connected to the connecting rod 11, and the side wall of the arc-shaped telescopic rod 13 is sleeved with a spring 14, the spring 14 abuts against the toggle rod 12, and the end of the spring 14 away from the toggle rod 12 abuts against the connecting rod 11.

[0027] When the soil to be tested is collected, the door provided on the front of the chassis 1 is opened, the test box 9 is lifted upward, and then the test box 9 is taken out, and the test is carried out by injecting a test solution into the test box 9 (such as a farmland soil pollution monitoring device with publication number CN218271427U, which discloses a method of detecting soil by using a test solution, which has the same working principle as the above-mentioned injection of a test solution for testing, and therefore is not described in detail in this case).

[0028] After the sampling device 4 has finished sampling, the electric push rod 3 pulls the sampling device 4 to move in the direction away from the through hole 5, so that the sampling device 4 moves to the top of the detection box 9, and the sampling device 4 operates in the reverse direction to make the soil sample fall into the detection box 9. When the electric push rod 3 pulls the sampling device 4 to move in the direction away from the through hole 5, the connecting rod 11 drives the toggle rod 12 to move in the direction away from the through hole 5. Since the connecting rod 11 limits the toggle rod 12, the detection box 9 is pushed to rotate around the rotating shaft 7 to realize automatic replacement of the detection box 9. When the electric push rod 3 pushes the sampling device 4 to move in the direction close to the through hole 5, the connecting rod 11 cannot limit the toggle rod 12, the toggle rod 12 rotates, and then the toggle rod 12 cannot normally toggle the detection box 9, so that the detection box 9 is reset. By automatically switching the detection box 9, continuous replacement of the soil is realized, and the efficiency of soil detection is improved. At the same time, when the soil is collected in the detection box 9, the detection box 9 rotates under the cover plate 10, thereby preventing the soil from being thrown out due to the rotation of the chassis 1.

[0029] In addition, a groove 16 is provided at the bottom of the detection box 9, and a hemisphere 15 is fixedly connected to the inner bottom surface of the chassis 1, and the hemisphere 15 is snapped into the groove 16. When the detection box 9 is rotated to the top of the hemisphere 15, the hemisphere 15 is snapped into the groove 16, so that the detection box 9 can be in a precise position to receive the soil collected by the sampling device 4, while avoiding slight deviation of the detection box 9 due to the resetting of the toggle rod 12, thereby realizing continuous soil sample replacement and accurate positioning.

[0030] In the utility model, when in use, the sampling device 4 moves to the top of the detection box 9, so that the soil sample falls into the detection box 9, and the soil is collected. When the sampling device 4 reciprocates, the detection box 9 is automatically replaced by the connecting rod 11 and the toggle rod 12. After collecting a soil sample, the new detection box 9 can be automatically moved into the sampling position of the sampling device 4 to improve the detection efficiency. Furthermore, when the detection box 9 rotates to the top of the hemisphere 15, the hemisphere 15 is stuck in the groove 16, so that the detection box 9 can be in a precise position to receive the soil collected by the sampling device 4, thereby realizing accurate positioning of the detection box 9.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
