Description

Technical Field

[0001] The utility model relates to a soil detection sampling device, belonging to the technical field of soil sampling equipment. Background Art

[0002] Soil environmental monitoring refers to determining the environmental quality (or degree of pollution) and its changing trends by measuring the representative values of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as point sampling, sample preparation, analysis methods, result characterization, data statistics and quality evaluation. A sampling device is required in the process of soil sampling. When sampling soil, the sampler of the sampling device needs to be inserted into the target soil layer, and then the soil in the target soil layer is taken out.

[0003] In order to ensure the accuracy of the samples, the existing soil sampling devices can only sample soil from one soil layer at a time. When sampling is required for multiple soil layers, it is necessary to enter the target soil layers and extract them one by one. This operation requires the samplers to frequently insert the target soil layers and take out the soil, which is time-consuming to implement. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a soil detection sampling device.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A soil detection sampling device comprises a support plate, a threaded hole is formed in the middle of the support plate, a threaded rod is threadedly connected in the threaded hole, a sampling tube is threadedly connected at the bottom end of the threaded rod, a cone head is provided at the bottom end of the sampling tube, a sampling port is provided on the surface of the sampling tube, and a receiving component matching the sampling port is provided in the sampling tube.

[0007] Furthermore, the receiving assembly includes a bottom plate located at the top of the sampling tube, a motor is provided in the middle of the inner top of the bottom plate, a support rod is provided at the output end of the motor, a large gear is fixedly connected to the outer surface of the support rod, a rotating plate is sleeved on the other end of the outer surface of the support rod, four slide grooves are provided on a side of the rotating plate close to the bottom plate, and an arc surface is provided between two adjacent slide grooves.

[0008] Furthermore, a support rod 2 is provided on one side of the top of the base plate, a small gear and a connecting rod are provided on the outer surface of the support rod 2, the small gear is meshed with the large gear, an arc surface 2 is provided at one end of the connecting rod, the arc surface 2 is in contact with the arc surface 1, a sliding rod is provided at the bottom of the other end of the connecting rod, and the sliding rod cooperates with the sliding groove.

[0009] Furthermore, four collecting boxes are evenly arranged on the top of the rotating plate, and the collecting boxes cooperate with the sampling ports.

[0010] Furthermore, a cylindrical ring is provided on the top of the sampling tube, an external thread is provided on the outer surface of the cylindrical ring, and an internal thread matching with the external thread is provided on the inner bottom of the threaded rod.

[0011] Furthermore, the inner wall of the sampling tube is provided with a receiving groove, an electric telescopic rod is provided in the receiving groove, and a sealing plate is provided at the output end of the electric telescopic rod, and the sealing plate cooperates with the sampling port.

[0012] Furthermore, a rotating disk is provided at the top end of the threaded rod, and two positioning pins are provided at the bottom end of the support plate.

[0013] Furthermore, a surface of the collecting box close to the sampling port is lower in height than a surface away from the sampling port.

[0014] The beneficial effects of the utility model are:

[0015] Through the setting of the receiving component, the receiving component can drive the collecting box to rotate to the position of the sampling port, so that when sampling is performed, the soil can enter the collecting box through the sampling port. The setting of multiple collecting boxes can perform multiple samplings at the same time, and there is no need to take the device out of the soil layer for the next sampling step, which improves the use efficiency and work efficiency of the device.

[0016] Through the setting of the sealing plate, the sealing plate can seal the sampling port when the threaded rod drives the sampling tube to descend, thereby preventing soil from entering the sampling port and preventing soil from other places from mixing into the sample sampled from the target soil layer, which can easily lead to a reduction in the accuracy of the sampled samples, thereby reducing the accuracy of the soil detection results.

[0017] Through the setting of the electric telescopic rod and the sealing plate, before the sampling tube contacts the target soil layer, the electric telescopic rod can drive the sealing plate to seal the sampling port. At this time, the sampling port is in a sealed state, so the soil cannot enter the sampling tube. When the soil layer to be sampled is reached, the electric telescopic rod drives the sealing plate to leave the sampling port. At this time, the seal of the sampling port is released, so that the target soil sample can enter the collection box in the sampling tube, thereby ensuring the accuracy of the sample.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Through the setting of the receiving component, the receiving component can drive the collecting box 19 to rotate to the position of the sampling port 5, so that when sampling, the soil can enter the collecting box 19 through the sampling port 5. The setting of multiple collecting boxes 19 can perform multiple samplings at the same time, and there is no need to take the device out of the soil layer and then perform the next sampling step, which improves the use efficiency and work efficiency of the device.

[0031] See also Figure 4 and Figure 5 Four collecting boxes 19 are evenly arranged on the top of the rotating plate 12, and the collecting boxes 19 cooperate with the sampling port 5. A cylindrical ring 22 is arranged on the top of the sampling tube 3, and an external thread is arranged on the outer surface of the cylindrical ring 22. The inner bottom of the threaded rod 2 is provided with an internal thread that cooperates with the external thread.

[0032] See also Figure 1 , Figure 8 The inner wall of the sampling tube 3 is provided with a receiving groove, and an electric telescopic rod is provided in the receiving groove. A sealing plate 6 is provided at the output end of the electric telescopic rod, and the sealing plate 6 cooperates with the sampling port 5. Through the setting of the sealing plate 6, the sealing plate 6 can block the sampling port 5 when the threaded rod 2 drives the sampling tube 3 to descend, thereby preventing soil from entering the sampling port 5 and preventing soil from other places from mixing into the sample sampled from the target soil layer, which can easily lead to a reduction in the accuracy of the sampled sample, thereby reducing the accuracy of the soil detection result. A turntable 4 is provided at the top of the threaded rod 2, and two positioning pins 21 are provided at the bottom end of the support plate 1. The height of the side of the collecting box 19 close to the sampling port 5 is lower than the side away from the sampling port 5.

[0033] When in use, the device is brought to the surface of the soil layer where sampling is required, and then the turntable 4 is rotated, and the turntable 4 drives the threaded rod 2 to rotate. With the cooperation of the threaded hole, the threaded rod 2 drives the cone head 20 and the sampling tube 3 to be inserted into the soil (before the sampling tube 3 contacts the target soil layer, the electric telescopic rod drives the sealing plate 6 to seal the sampling port 5, so the soil cannot enter the sampling tube 3 through the sampling port 5). When the soil layer to be sampled is reached, the electric telescopic rod is started to drive the sealing plate 6 to leave the sampling port 5. At this time, the target soil sample enters the collection box 19 in the sampling tube 3 through the sampling port 5. Then the electric telescopic rod is started again to drive the sealing plate 6 to seal the sampling port 5. The turntable 4 is rotated in the opposite direction, and the turntable 4 drives the sampling tube 3 to move upward. At this time, sampling is completed;

[0034] When it is necessary to sample soil layers at different depths, at this time, it is only necessary to drive the sampling tube 3 in the device to move to the depth where sampling is required, and randomly, start the receiving component to rotate several collecting boxes 19 in sequence to the position matching the sampling port 5, so that soil at different depths can be sampled without driving the device to leave the soil layer multiple times to place samples, start the motor 8, the motor 8 drives the support rod 9 to rotate, the support rod 9 drives the large gear 11 to rotate, the large gear 11 drives the small gear 15 meshing with it to rotate, the small gear 15 rotates and drives the connecting rod 17 to rotate, when When the slide bar 18 slides into the slide groove 14, it will drive the rotating plate 12 to rotate. When the slide bar 18 leaves the slide groove 14, the arc surface 2 16 contacts the arc surface 1 13. At this time, the rotating plate 12 does not rotate. When the arc surface 2 16 contacts the arc surface 1 13, it will stop. The connecting rod 17 rotates one circle, and the rotating plate 12 rotates 90 degrees. At this time, the operation of the motor 8 is stopped. At this time, the collecting box 19 on the top of the arc surface 13 rotates to the position of the sampling port 5, so that the sample enters the collecting box 19 through the sampling port 5, and the process of sampling multiple samples can be realized.

[0035] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
