Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a collecting device for soil sampling. Background Art

[0002] Soil sampling is the basic work of soil science research. Representative soil samples are obtained through scientific deployment and standardized operation. During the sampling process, attention should be paid to time, method, depth and sample handling to ensure accurate and reliable results. Sampling results can provide important basis for soil quality assessment, environmental monitoring and agricultural production.

[0003] The existing small and medium-sized soil sampling and collection devices are to take out the sampled soil plastic bucket, cut it with a utility knife, and then take out the soil, which leads to two problems:

[0004] 1. After the sampling barrel is cut open, the loose soil may be peeled off and scattered in disorder, which is not only troublesome to collect, but also easy to cause sample contamination;

[0005] 2. Using a manual knife to break the sampling barrel is a dangerous operation.

[0006] Therefore, it is necessary to design a collecting device that is convenient for taking out the soil in the sampling bucket. Utility Model Content

[0007] In order to overcome the shortcomings of the existing soil sampling method that the soil is easily scattered and causes sample contamination, and it is dangerous to use a knife to break the sampling barrel, the utility model provides a soil sampling collection device that is convenient for taking out the soil in the sampling barrel.

[0008] A collecting device for soil sampling includes a base plate, a servo motor, a screw rod, a guide rod, an extrusion plate and a cutter. The base plate is provided with a placement groove with an arc bottom surface. The screw rod and the guide rod are arranged in parallel in the base plate. The servo motor is fixed to the side of the base plate by bolts. The output shaft of the servo motor transmits the screw rod through a coupling. The extrusion plate is slidably connected to the guide rod and is simultaneously connected to the screw rod by threads. The cutter is arranged on the side of the base plate and can dock with the placement groove.

[0009] Further, one side of the blade of the tool points to the placement groove.

[0010] Furthermore, it also includes a control button, which is arranged on the side of the base plate and is electrically connected to the servo motor.

[0011] Furthermore, it also includes a support frame and a collection box. The support frame is fixed to one side of the base plate by bolts, specifically to the side where the tool is fixed. The collection box is slidably connected to the support frame by splines.

[0012] Furthermore, it also includes a pull rod, which is connected to the side of the collection box.

[0013] Furthermore, it also includes an adjusting foot, which is arranged at the lower end of the base plate and can be adjusted in height by rotating.

[0014] Furthermore, it also includes handles, which are arranged opposite to each other and fixed to the two sides of the bottom plate.

[0015] Furthermore, an anti-slip pad is provided on the handle.

[0016] Furthermore, a protective cover is included, and the protective cover is sleeved on the tool by a snap-fitting manner.

[0017] The beneficial effect is: the servo motor is turned on by the control button, and when the servo motor drives the screw rod to rotate, the extrusion plate can be pushed to move horizontally. The extrusion plate pushes the sampling tube located in the placement groove to the side of the tool, and the tool cuts the side wall of the sampling tube, and the soil in the sampling tube will fall into a slidable and removable collection box. This device not only avoids sample contamination caused by disorderly dispersion of the soil, but also automates the action of cutting off the sampling tube, reducing the danger of manual operation.

[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment: A collection device for soil sampling, such as Figure 1-Figure 3As shown, it includes a base plate 1, a servo motor 3, a screw rod 4, a guide rod 5, an extrusion plate 6 and a tool 7. The base plate 1 is provided with a placement groove 2 with an arc bottom surface. The screw rod 4 and the guide rod 5 are arranged in parallel in the base plate 1. The servo motor 3 is fixed to the side of the base plate 1 by bolts. The output shaft of the servo motor 3 drives the screw rod 4 through a coupling. The extrusion plate 6 is slidably connected to the guide rod 5 and is simultaneously connected to the screw rod 4 by threads. The tool 7 is arranged on the side of the base plate 1. One side of the blade of the tool 7 points to the placement groove 2. The tool 7 can dock with the placement groove 2. When the servo motor 3 is turned on to drive the screw rod 4 to rotate, the screw rod 4 will drive the extrusion plate 6 to move horizontally, and the bottom of the extrusion plate 6 is accurately embedded in the placement groove 2. Therefore, the extrusion plate 6 pushes the sampling barrel to the tool 7, and the tool 7 will also cut and break the side of the sampling barrel.

[0024] like Figure 2 As shown, a control button 8 is also included. The control button 8 is arranged on the side of the base plate 1 , and the control button 8 is electrically connected to the servo motor 3 .

[0025] like Figure 3 As shown, it also includes a support frame 9 and a collection box 10. The support frame 9 is fixed to one side of the base plate 1 by bolts, specifically to the side where the tool 7 is fixed. The collection box 10 is connected to the support frame 9 through a spline sliding connection. A pull rod 11 is connected to the side of the collection box 10. The pull rod 11 facilitates the staff to pull the collection box 10 horizontally.

[0026] like Figure 1 As shown, it also includes an adjustable foot 12, a handle 13 and a protective cover 15. The adjustable foot 12 is set at the lower end of the base plate 1. The adjustable foot 12 can be adjusted in height by rotation. The handles 13 are oppositely arranged and fixedly connected to both sides of the base plate 1. The staff can lift and place the device by holding the handles 13. The handle 13 is provided with an anti-slip pad 14, and the protective cover 15 is mounted on the tool 7 by a snap-on manner.

[0027] Working principle: the staff uses the sampling tool to push the sampling tube deep into the ground and then take it out, and then put the sampling tube into the placement groove 2, and turn on the servo motor 3 through the control button 8. The servo motor 3 drives the screw rod 4 to rotate, and the screw rod 4 will push the extrusion plate 6 to move horizontally. The extrusion plate 6 pushes the sampling tube located in the placement groove 2 to the side of the tool 7. When the sampling tube passes through the tool 7, the tool 7 will cut the side wall of the sampling tube, and the soil in the sampling tube will fall into the collection box 10. A horizontally sliding collection box 10 is provided to facilitate the staff to take the sampled soil.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
