Description
Technical Field
[0001] This utility model relates to the field of agricultural science and technology, and in particular to a portable soil sampler. Background Technology
[0002] A portable soil sampler is a small, portable, professional tool used to collect soil samples. It comes into direct contact with the soil, cutting into and breaking up soil layers. Its shape and material are designed according to different soil textures and sampling requirements. Common types include auger bits, spoon bits, and fishtail bits. For example, auger bits use spiral blades to transport soil upwards as they rotate, making it easy to collect soil; spoon bits can be used to scoop up soil samples like a spoon.
[0003] In practical use, existing portable soil samplers are not easy to rotate. When facing some relatively hard soils, such as highly sticky clay or slightly compacted loam, it is difficult to effectively break the soil by simply pressing down, and the drilling speed of the soil sampler will be significantly slowed down.

[0015] Beneficial effects
[0016] This utility model provides a portable soil sampler, which has the following beneficial effects:
[0017] 1. This portable soil sampler, through the setting of the rotating component, allows users to grasp the two handles, insert the outer shell into the soil, and place their feet on the two foot pads. When the outer shell cannot go any further, the motor is started. The motor drive drives one of the rotating wheels to rotate, which in turn drives the transmission belt to rotate the other rotating wheel, and drives the mounting plate and sliding plate to enter the soil along with the mounting plate. Because the sliding plate has a connecting rod inside, and the spiral blade is screwed on the outer circumference of the connecting rod in a reverse screw manner, it can effectively increase the drilling speed. The rotating component can make the drill bit rotate at high speed under power drive, and its cutting edge can continuously apply cutting force to the soil, like a sharp knife cutting an object, quickly breaking through various soil layers, whether it is relatively soft sandy loam or clay and silt with a certain degree of hardness, it can be broken by the drill bit more efficiently, allowing the soil sampler to advance smoothly downward, thereby accelerating the drilling speed.
[0018] 2. This portable soil sampler, through the setting of the measuring component, when the motor is started, drives the sliding plate to slide inside the mounting block one, and brings the sliding plate into the soil for sampling. After sampling, the soil length can be measured according to the scale line. The measuring component can display the current depth position of the soil sampler in real time and accurately. Based on these measurement data, the operator can accurately control the soil sampler to drill down to the specified depth range for sampling, thereby ensuring that the collected samples can accurately correspond to the corresponding strata, realizing the scientific and accurate nature of layered soil sampling.

The rotating assembly 2 includes a motor 201, which is fixedly connected inside the mounting plate 1. One of the rotating wheels 202 is fixedly connected to the drive end of the motor 201. A transmission belt 203 is rotatably connected to the outer circumference of one of the rotating wheels 202, and another rotating wheel 202 is rotatably connected to the inner side of the transmission belt 203. Both rotating wheels 202 are rotatably connected to the outer circumference of the other rotating wheel 202. Inside the transmission belt 203, one of the rotating wheels 202 is rotatably connected to the inside of the mounting plate 1; the measuring component 3 includes a first mounting block 301, which is fitted inside the outer casing 8. The first mounting block 301 has a sliding plate 302 and a second mounting block 303 slidably connected inside it. The top of the sliding plate 302 is fixedly connected to the bottom of the second mounting block 303. The motor 201, the rotating wheel 202, and the transmission belt 203 are arranged to achieve rotation. The first mounting block 301, the sliding plate 302, the mounting rod 303, and the second mounting block 304 are arranged to achieve measurement.
[0026] Another rotating wheel 202 has a fixed rod 4 fixedly connected to its inner side. The fixed rod 4 is rotatably connected to the inside of the mounting plate 1. The outer shell 8 has a scale line 7 inside, which serves as a measurement tool.
[0027] A connecting block 10 is fixedly connected to the outer periphery of the fixing rod 4. The bottom of the connecting block 10 is fixedly connected to the top of the outer shell 8. The fixing rod 4 serves to slide the sliding plate 302.
[0028] The top of the connecting block 10 abuts against the bottom of the mounting plate 1, and the connecting block 10 serves to support the mounting plate 1.
[0029] A sliding block 6 is fixedly connected to the bottom of the fixed rod 4. The sliding block 6 is fixedly connected to the top of the mounting block 2 303. The sliding block 6 serves to fix the rod.
[0030] Two handles 5 are fixedly connected to the outer periphery of the mounting plate 1, and two feet 11 are fixedly connected to the outer periphery of the outer shell 8. The two handles 5 provide overall support.
[0031] Mounting block 2 303 is fixedly connected to a limiting rod 9 on its outer periphery. The limiting rod 9 is slidably connected inside mounting block 1 301. The limiting rod 9 is set to limit the movement.
[0032] A connecting rod 13 is fixedly connected to the bottom inside the sliding plate 302. A spiral blade 12 is fixedly connected inside the connecting rod 13. Multiple teeth 14 are fixedly connected to the bottom of the connecting rod 13. The spiral blade 12 and the connecting rod 13 are configured to increase the speed.
[0033] Motor 201 model is Y112M-6: The above parameters and model can be selected according to the actual situation.
[0034] In this invention, the working steps of the device are as follows:
[0035] First step: When using, hold the two handles 5, insert the outer casing 8 into the soil, and place your feet on the two foot pads 11. When the outer casing 8 can no longer go down, start the motor 201. The drive end of the motor 201 drives one of the rotating wheels 202 to rotate. When one of the rotating wheels 202 rotates, it drives the transmission belt 203, and the other rotating wheel 202 rotates. This drives the second mounting block 303 and the sliding plate 302 to take soil into the soil along with the first mounting block 301. Because the sliding plate 302 is equipped with a connecting rod 13 and the spiral blade 12 is screwed on the outer circumference of the connecting rod 13 in a reverse screw manner, it can effectively increase the drilling speed. The rotating component 2 can make the drill bit rotate at high speed under the power drive. Its cutting edge can continuously apply cutting force to the soil, like a sharp knife cutting an object, quickly breaking through various soil layers. Whether it is relatively soft sandy loam or clay and silt with a certain degree of hardness, it can be broken by the drill bit more efficiently, so that the soil sampler can be pushed down smoothly, thereby speeding up the drilling speed.
[0036] The second step: When the starting motor 201 drives the sliding plate 302 to slide inside the mounting block 301, the sliding plate 302 is brought into the soil for sampling. After sampling, the soil length can be measured according to the scale line 7. The measuring component can display the current depth position of the soil sampler in real time and accurately. Based on these measurement data, the operator can accurately control the soil sampler to drill down to the specified depth range for sampling, thereby ensuring that the collected samples can accurately correspond to the corresponding strata and realize the scientificity and accuracy of layered soil sampling.
