Description

Technical Field

[0001] This utility model relates to the field of sampling tube technology, specifically to a foot-operated deep heavy metal sampling tube for cultivated land. Background Technology

[0002] The content of heavy metals (such as cadmium, lead, and mercury) in deep soil layers of arable land is a key indicator for assessing the environmental quality of arable land and formulating pollution remediation plans. The sampling process requires inserting a sampling tube into the soil to obtain a complete soil profile sample. Existing deep soil heavy metal sampling tubes are mostly single tubular structures with a top handle. After the sampling tube is inserted into the deep soil, the friction and cohesion of soil particles on the tube are extremely high. After sampling, the operator needs to grip the top handle tightly with both hands and pull it upwards. A single person needs to apply a large pulling force continuously, which not only easily leads to hand fatigue and wrist pain, but also requires 2 to 3 people to pull it together, resulting in high labor costs. Utility Model Content

[0003] In view of the problems existing in the current foot-operated deep heavy metal sampling tubes for cultivated land, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a foot-operated deep heavy metal sampling tube for cultivated land, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foot-operated deep heavy metal sampling tube for cultivated land includes a base plate and a sampling tube body. The surface of the base plate has a through hole, and the sampling tube body is slidably fitted inside the through hole. A vertical rod is fixedly installed on the upper surface of the base plate and on one side of the sampling tube body. A sliding plate is slidably fitted at the middle end of the vertical rod. A pedal is abutted on the upper surface of the sampling tube body. One side of the sliding plate is fixedly connected to the pedal. A pushing mechanism for moving the pedal is provided at the upper end of the vertical rod, and a limiting mechanism for maintaining the stable movement of the sampling tube body is provided on the lower end of the vertical rod.

[0007] Preferably, the pushing mechanism includes push rods and pins. The push rods are disposed on both sides of the pedal. The side wall of the pedal has a first strip-shaped opening. The pins slide through the inner side of the first strip-shaped opening. Both ends of the pins are fixedly connected to one end of the corresponding push rods. The upper end of the vertical rod is rotatably sleeved with a rotating rod. Both ends of the rotating rod are fixedly connected to the middle end of the corresponding push rod. A connecting rod is fixedly disposed between the ends of the two push rods away from the pins. Two extension rods are fixedly sleeved on the wall of the connecting rod.

[0008] Preferably, the limiting mechanism includes a fixed rod and a slider. The lower end of the vertical rod, on the side closest to the main body of the sampling tube, has a second slot. The fixed rod is fixedly disposed inside the second slot. The slider is movably sleeved on the wall of the fixed rod. Connecting blocks are provided on both sides of the slider. One side of each connecting block is fixedly connected to the outer wall of the main body of the sampling tube. Through holes are provided on the side walls of both connecting blocks. A threaded hole is provided on the side wall of the slider. A threaded rod passes through the through holes on both sides. The middle end of the threaded rod is threadedly connected to the threaded hole of the slider.

[0009] Preferably, a pressure bar is fixedly provided between the ends of the two extended rods that are away from the connecting rod.

[0011] Preferably, the longitudinal section of both the slider and the second slot is rectangular, and both sides of the slider abut against the inner wall of the second slot.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model allows the sampling tube body to be inserted into the cultivated land for sampling by stepping on the pedal, which moves the pedal downward. Then, pressing down on the pressure rod causes the extension rod to push the connecting rod, which in turn causes the push rod to rotate around the rotating rod. This allows the round pin to slide within the slot of the pedal, thus pushing the pedal upward. This allows the sampling tube body to be removed from the cultivated land in a time-saving and labor-saving manner.

[0014] 2. In this utility model, by rotating the threaded rod, the connection between the connecting block and the slider can be released, thereby disassembling the main body of the sampling tube and facilitating maintenance of the main body of the sampling tube. Attached Figure Description

[0023] This utility model discloses a foot-operated deep heavy metal sampling tube for cultivated land.

[0024] Reference Figure 1-4 A foot-operated deep heavy metal sampling tube for cultivated land includes a base plate 1 and a sampling tube body 2. The surface of the base plate 1 has a through hole, and the sampling tube body 2 is slidably fitted inside the through hole. The lower end of the sampling tube body 2 is serrated, which makes it easier to insert the sampling tube body 2 into the cultivated land. A vertical rod 5 is fixedly installed on the upper surface of the base plate 1 and on one side of the sampling tube body 2. A sliding plate 6 is slidably fitted at the middle end of the vertical rod 5. A foot pedal 3 is abutted on the upper surface of the sampling tube body 2. One side of the sliding plate 6 is fixedly connected to the foot pedal 3. A pushing mechanism is provided at the upper end of the vertical rod 5 to drive the foot pedal 3 to move. A limiting mechanism is provided on the lower end of the vertical rod 5 to keep the sampling tube body 2 moving stably.

[0025] Reference Figure 1-4 The pushing mechanism includes push rods 9 and pins 4. Push rods 9 are located on both sides of pedal 3. A first slot is opened on the side wall of pedal 3. Pins 4 slide through the inside of the first slot. Both ends of pins 4 are fixedly connected to one end of the corresponding push rod 9. A rotating rod 8 is rotatably sleeved on the upper end of vertical rod 5. Both ends of rotating rod 8 are fixedly connected to the middle end of the corresponding push rod 9. A connecting rod 7 is fixedly installed between the ends of the two push rods 9 away from pins 4. Two extension rods 10 are fixedly sleeved on the wall of connecting rod 7. A pressure rod 11 is fixedly installed between the ends of the two extension rods 10 away from connecting rod 7 to facilitate pressing the two extension rods 10.

[0026] Reference Figure 1-4The limiting mechanism includes a fixed rod 12 and a slider 13. The lower end of the vertical rod 5, located on the side close to the sampling tube body 2, has a second slot. The fixed rod 12 is fixedly installed inside the second slot. The slider 13 is movably sleeved on the rod wall of the fixed rod 12. Connecting blocks 14 are provided on both sides of the slider 13. One side of the connecting block 14 is fixedly connected to the outer wall of the sampling tube body 2. Through holes are provided on the side walls of the two connecting blocks 14.

The middle end of the threaded rod 15 is threadedly connected to the threaded hole of the slider 13. The longitudinal section of the slider 13 and the second slot is rectangular. Both sides of the slider 13 abut against the inner wall of the second slot, so that the slider 13 can slide stably within the second slot.

[0027] In this invention, when in use, the device is moved to the sampling point so that the base plate 1 is laid flat. Both feet step on the pedal 3 and press down, causing the slide plate 6 to slide along the vertical rod 5. The main body 2 of the sampling tube is inserted into the deep soil through the serrated end. The slider 13 slides along the fixed rod 12 simultaneously to prevent tilting. After releasing the pedal, both hands hold the pressure rod 11 and press down. Through the extension rod 10 and the connecting rod 7, the push rod 9 is driven to rotate around the rotating rod 8. The round pin 4 slides in the strip opening of the pedal 3 and pushes the pedal 3 upward, thereby pulling the main body 2 of the sampling tube upward. By leveraging the principle, it can be pulled out by a single person applying force, which greatly saves manpower.
