Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling equipment, and specifically relates to a soil sampling device for agronomists. Background Technique

[0002] A soil sampling device is a tool for collecting soil samples, mainly used in fields such as agronomy, environmental monitoring, and soil science research. The sampling device can help agronomists better understand information such as the properties, fertility, and water content of the soil, so as to provide a scientific basis for crop planting. The sampling device is mainly used for soil fertility work such as soil testing and formula fertilization, soil monitoring, etc. It can accurately collect soil samples, solve the problems in the sampling process. A professional sampling device can meet the requirements of full-layer, equal-quantity, and convenient soil sampling, control the sampling error to the maximum extent, and meet the needs of professional evaluation.

[0003] Meanwhile, the patent document with the application number 202321680566.4 discloses a soil sampling device for agronomists, including a rectangular plate. A sampling structure is arranged on the rectangular plate. The sampling structure includes: a notch, a top frame, a soil-opening component, and a soil-taking component. The notch is opened at opposite ends of the rectangular plate. The top frame is fixed on the rectangular plate. The soil-opening component is arranged in the top frame and the notch. The soil-taking component is arranged on the rectangular plate. A bucket is arranged at the bottom of the rectangular plate. The bucket can be inserted into the ground, and at the same time, the rectangular plate is attached to the ground. The bucket can be driven by the screw, rotating frame, fixed rod, and connecting rod of the soil-opening component to pull the bucket to turn outwards, turning over the soil layer. After turning over, a soil sampling mold is inserted to take out the soil sample inside the soil layer, and the operation is simple and convenient.

[0004] In the process of using the existing soil sampling device for agronomists, due to the absence of a storage device, only one depth of sample can be collected at a time, and samples of different depths cannot be sampled. Due to the absence of an efficient transmission device, in some cases, the sampler needs to sample the land with relatively hard geology, and it is difficult to sample the relatively hard land, resulting in a decrease in sampling efficiency and inaccurate sampling results.

[0005] Therefore, a soil sampling device for agronomists is proposed to solve the above problems. Summary of the Invention

[0006] To solve the problems raised in the above background technique, the utility model provides a soil sampling device for agronomists, which has the advantages of high sampling efficiency and the ability to collect samples of different depths at one time.

[0007] To achieve the above object, the present utility model provides the following technical solution: An agronomist soil sampling device, comprising a device main body, one end of the device main body is fixedly connected with a sliding groove, a slider is slidably connected inside the sliding groove, one end of the slider is fixedly connected with a sampling steel pipe, a meshing tooth is fixedly arranged on the outer side of the sampling steel pipe, a first gear is meshed with the outer side of the meshing tooth, a first rotating shaft is fixedly connected inside the first gear, a second gear is fixedly connected to the outer side of one end of the first rotating shaft, a third gear is meshed with the outer side of the second gear, a fixed shaft is fixedly connected to one side of the third gear, and a disc is fixedly connected to one end of the fixed shaft.

[0008] Preferably, a second rotating shaft is rotatably connected to one side of the disc, and a second rubber handle is fixedly connected to the outer side of the second rotating shaft.

[0009] Preferably, a sampling pipe is slidably connected inside the sampling steel pipe, and a screw cap is spirally connected to the top end of the sampling steel pipe.

[0010] Preferably, a first fixing block is fixedly connected to the bottom end of one side of the device main body, and a support column is fixedly connected to the top end of the device main body.

[0011] Preferably, a second fixing block is fixedly connected to the top end of the support column, and a box body is fixedly connected to one side of the device main body.

[0012] Preferably, two first rubber handles are fixedly connected to both ends of the second fixing block, and the number of the first rubber handles is set to two.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. When a user uses the soil sampling device, first, the sampling device can be placed at the position where sampling is required. Subsequently, step on the first fixing block to prevent the sampling device from generating displacement during the sampling process, which affects the accuracy of sampling. After accurately positioning the sampling position, hold the second rubber handle and drive the disc to rotate. The disc drives the third gear to rotate through the fixed shaft. The third gear is meshed with the second gear, and the second gear and the first gear are fixed to the same rotating shaft inside. The second gear drives the first gear to rotate through the rotating shaft. The first gear is meshed with the meshing tooth to drive the sampling steel pipe to move up or down. This device increases the torque, enabling the staff to collect more samples with less effort during sampling, reducing the physical consumption of the collectors, and accelerating the collection efficiency.

[0015] 2. The utility model combines a screw cap, a sampling steel pipe, a sampling tube and a slider structure. Before using the soil sampling device, the sampler can first clean the remaining soil samples in the sampling tube inside the sampling steel pipe. Then, the sampling tube is inserted into the sampling steel pipe from the top of the sampling steel pipe. Rotate the screw cap, and the screw cap will restrict the movement of the sampling tube, so that the sampling tube is always inside the sampling steel pipe during the sampling process. Rotate the rubber handle II, and the sampling tube will collect all the soil samples from the ground surface to the sampling depth. Then, push the sampling steel pipe upward, rotate the screw cap to open the sampling steel pipe, take out the sampling tube to collect the samples. The sampling tube is made of transparent material, which is more convenient for the sampler to identify and recognize. This device reduces the number of samplings and can collect samples of multiple different depths at one time, increasing the sampling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5As shown in the figure, the utility model provides a soil sampling device for agronomists, which includes a device main body 1. One end of the device main body 1 is fixedly connected with a sliding groove 7. A slider 8 is slidably connected inside the sliding groove 7. One end of the slider 8 is fixedly connected with a sampling steel pipe 9. A meshing tooth 12 is fixedly arranged on the outer side of the sampling steel pipe 9. A first gear 13 is meshed with the outer side of the meshing tooth 12. A first rotating shaft 14 is fixedly connected inside the first gear 13. A second gear 15 is fixedly connected to the outer side of one end of the first rotating shaft 14. A third gear 16 is meshed with the outer side of the second gear 15. One side of the third gear 16 is fixedly connected with a fixed shaft 17. One end of the fixed shaft 17 is fixedly connected with a disc 18. Multiple gears form a gear set, which enables the sampling personnel to improve the sampling efficiency, reduce the effort required for sampling, and make it more convenient to sample soil with harder texture.

[0024] Specifically, one side of the disc 18 is rotatably connected with a second rotating shaft 19. A second rubber handle 20 is fixedly connected to the outer side of the second rotating shaft 19. The second rubber handle 20 increases the comfort of the sampling personnel during sampling.

[0025] Furthermore, a sampling tube 11 is slidably connected inside the sampling steel pipe 9. A screw cap 10 is spirally connected to the top of the sampling steel pipe 9. The screw cap 10 restricts the upward movement of the sampling tube 11, making the sampling result more accurate.

[0026] Still further, a first fixing block 2 is fixedly connected to the bottom end of one side of the device main body 1. A support column 3 is fixedly connected to the top of the device main body 1. The support column 3 transmits force to the first rubber handle 5 through a second fixing block 4.

[0027] It is worth noting that a second fixing block 4 is fixedly connected to the top of the support column 3. A box body 6 is fixedly connected to one side of the device main body 1. The box body 6 can prevent external objects from getting stuck in the gear set.

[0028] It should be noted that both ends of the second fixing block 4 are fixedly connected with a first rubber handle 5, and the number of the first rubber handles 5 is set to two. The first rubber handle 5 can enable the sampling personnel to move and press the sampling device more comfortably.

[0029] Among them, the sampling tube 11, the first rotating shaft 14, the meshing tooth 12 and the first rubber handle 5 are prior arts and will not be elaborated here; at the same time, the utility model also includes studs, springs, screws, etc., which are not the main technical points of this patent and will not be elaborated here.

[0030] Working principle and process: First, clear the soil sample remaining in the sampling tube 11 from the previous sampling. Insert the sampling tube 11 into the top inside of the collecting steel pipe 9. By rotating the screw cap 10, the sampling tube 11 is locked in place to ensure that it remains inside the collecting steel pipe 9 during sampling. Place the soil sampling device at the predetermined sampling point and use the foot to step on the fixed block 1 to prevent displacement during sampling and ensure the accuracy of sampling. After precise positioning, the operator can hold the rubber handle 20 and rotate the disc 18. The disc 18 will cause the gear 3 to rotate through the fixed shaft 17, and then mesh with the gear 2. Since the gear 2 and the gear 1 share the same rotating shaft 14, the interaction causes the gear 1 to rotate and mesh with the meshing teeth 12, thereby pushing the collecting steel pipe 9 to move up and down. The slider 8 on one side of the collecting steel pipe 9 will slide inside the sliding groove 7, and the sampling tube 11 will penetrate from the ground surface to the predetermined sampling depth to collect soil samples. After sampling, rotate the rubber handle 20 to lift the collecting steel pipe 9 and open it by rotating the screw cap 10 to remove the sampling tube 11, thereby collecting the soil samples. This device can collect soil samples at different depths simultaneously, improving the sampling efficiency. The design of the gear system greatly reduces the physical effort expended by the operator during sampling.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
