[0002] Soil is the basis of plant growth, and its quality is crucial to the yield and quality of crops. Therefore, the collection of soil samples for agrochemical properties is of great significance. First of all, soil sample collection is one of the key methods to understand soil fertility. By collecting soil samples, we can understand the distribution of various nutrient contents in the soil, such as nitrogen, phosphorus, potassium and other elements and trace elements. This information is of great significance for guiding farmers to apply fertilizers scientifically, increase crop yields and improve soil quality. In the prior art, when collecting land samples, the land samples are first dug out and then transferred to sample bags for storage. Since the samples cannot be stored directly after collection, when the collected samples are transferred to storage bottles or bags when the external environment is polluted, the samples are in contact with the external environment for a long time, which will affect the accuracy of subsequent sample detection data. Therefore, an integrated land sample collection and storage device is proposed to address the above problems. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. The integrated equipment for collecting and storing land samples is equipped with an electric push rod, a collecting bottle, a driving gear, a gear ring, a drill tube and a spiral blade. When collecting land samples through the device, the motor is controlled to drive the spiral blade to rotate. At this time, the spiral blade drives the driving gear to mesh with the driven gear, and further drives the drill tube to rotate in the opposite direction of the spiral blade through the gear ring. Then, the rotating drill tube is inserted into the sampling point by pressing the device with a handle. At this time, as the rotating drill tube is continuously inserted into the ground, the soil between the surface and the specified depth range will be continuously transported out by the rotating spiral blade. When the drill tube is inserted to the sampling depth and no soil is discharged from the bottom of the guide sleeve, the electric push rod is controlled to extend to move the collecting bottle to the bottom of the guide sleeve, and then the device is continued to be pressed to sample at the specified depth range. At this time, the samples at the specified depth will be continuously transported to the collecting bottle by the spiral blade under the guidance of the guide sleeve for collection. By directly storing the land samples at the specified depth in the collecting bottle after collecting, when the external environment is polluted, the samples can be prevented from being polluted by long-term contact with the external environment, thereby ensuring the accuracy of subsequent sample detection data.
[0012] 2. The integrated equipment for collecting and storing soil samples has a limit ring, a clamping rod, a scale, a slide plate and a spring. In the process of collecting soil samples through the device, the clamping rod is pulled to compress the spring of the slide plate, and the clamping rod is disengaged from the clamping strip. Then, the two limit rings are pushed up and down to slide respectively, so that the bottom end of the bottom limit ring points to the scale value on the scale as the minimum value of the sampling depth range, and the bottom end of the top limit ring points to the scale value on the scale as the maximum value of the sampling depth range plus the height of a limit ring. At this time, by setting two The limit rings mark the minimum depth and maximum depth of the sampling depth range respectively. When the pressing device makes the limit ring at the bottom contact with the ground and no soil is discharged from the guide sleeve, the device is continued to be pressed to make the inclined clamping rod at one end of the bottom slide continuously with the clamping strip, and further continuously control the sliding of the limit ring at the bottom and the drill tube. When the limit ring at the bottom contacts the limit ring at the top and no soil is discharged from the guide sleeve, it is convenient for the sampling personnel to collect and store land samples within the specified depth range, and the operation is simple and convenient.

[0025] Example 4
[0026] like Figure 1-3 As shown, in order to solve the problem that it is inconvenient to perform land sample collection operations within a specified depth range, a limit ring 16 is provided at the bottom end of the outer side of the drill tube 6, and there are two limit rings 16. The limit ring 16 is slidably connected to the drill tube 6, and a clamping rod 17 that penetrates the limit ring 16 is slidably connected to the outer side of the limit ring 16. One end of the clamping rod 17 is clamped and connected to a clamping strip 18 fixedly connected to the drill tube 6, and one end of the outer side of the clamping rod 17 is fixedly connected to a slide plate 19 slidably connected to the limit ring 16.

After adjusting the position of the collection bottle 15, the device is continued to be pressed to make the drill tube 6 continuously inserted into the ground to collect soil samples at a specified depth range. At this time, as the device is continued to be pressed, the card rod 17 inclined at one end of the bottom limit ring 16 will continue to When the drill pipe 6 is inserted into the ground, the soil sample at the specified depth will be continuously transported to the collecting bottle 15 by the spiral blade 5 for storage under the guidance of the guide sleeve 10. When the limiting ring 16 at the bottom contacts the limiting ring 16 at the top and no soil is discharged through the guide sleeve 10, the collection and storage of the soil samples at the specified depth range are completed. Finally, the collecting bottle 15 is rotated to disengage the spiral connection with the slider 14 to obtain the stored soil sample.
