Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil sampling device for agricultural technology promotion. Background Technology

[0002] Agricultural technology extension refers to the process of transforming agricultural scientific and technological achievements into real productivity. It covers all aspects of researching, developing, disseminating and applying new agricultural technologies, methods and concepts. Its core goal is to improve agricultural production efficiency, improve the quality of agricultural products, increase farmers' income, and ultimately promote sustainable agricultural development. Soil sampling is the foundation of precision agriculture and scientific fertilization.

[0003] In the existing technology, when using soil sampling devices and sampling components to sample the corresponding soil, uneven ground may occur during sampling, causing the sampling components to deviate from the predetermined direction, resulting in soil samples that are not representative and affecting the subsequent soil analysis results. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when using existing equipment, uneven ground can cause the sampling components to deviate from the predetermined direction during sampling, so a soil sampling device for agricultural technology promotion is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soil sampling device for agricultural technology promotion, comprising a base plate and an adjusting plate. Two fixing blocks are fixedly installed on the top of the base plate, and a fixing rod is fixedly installed between one side of the outer wall of the two fixing blocks. Two rotating blocks are movably sleeved on the outer wall of the fixing rod. An electric push rod is fixedly installed on the top of each of the two rotating blocks, and a connecting block is fixedly installed at the output end of each of the two electric push rods. A grooved block is fixedly installed on the bottom of the adjusting plate, and two rotating shafts are fixedly installed between the inner walls of the grooved block. The inner walls of the two connecting blocks are movably sleeved on the outer walls of the two rotating shafts. Two upright plates are fixedly installed on the top of the base plate.

[0006] Preferably, a rotating rod is fixedly installed between opposite sides of the outer walls of the two upright plates, and the inner surface of the adjusting plate is movably sleeved on the outer surface of the rotating rod.

[0007] Preferably, a level is fixedly installed on the top of the adjusting plate, and two concave columns are fixedly installed on the top of the adjusting plate.

[0008] Preferably, a forward and reverse motor is fixedly installed on the top of one of the concave columns, and a threaded rod is fixedly installed on the bottom of the forward and reverse motor.

[0009] Preferably, a strip plate is threadedly connected to the outer wall of the threaded rod, and a guide rod is fixedly installed between the inner walls of the other concave column, with the inner wall of the strip plate movably sleeved on the outer wall of the guide rod.

[0010] Preferably, a drive motor is fixedly installed on the top of the strip plate, and a sampling component is fixedly installed on the bottom of the drive motor.

[0011] Preferably, a controller is fixedly installed on the top of the adjustment plate, and one side of the outer wall of the controller is electrically connected to the outer wall of the two electric push rods, the forward and reverse motors and the drive motor.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, when the level indicator shows that the adjustment plate is not level, the controller activates two electric push rods. Since the two rotating blocks rotate on the fixed rod, and the two connecting blocks rotate on the two rotating shafts inside the grooved block, the extension and retraction of the two electric push rods can rotate the adjustment plate on the rotating rod, thereby adjusting the angle of the adjustment plate until the level indicator shows that the adjustment plate is level. This ensures that the sampling device and sampling components do not deviate from the predetermined direction during sampling, making the sampled soil sample representative and improving the accuracy of subsequent soil analysis results.

[0014] In this invention, once the position of the adjusting plate is adjusted, the drive motor is started by the controller, which drives the sampling component to rotate. At the same time, the forward and reverse motors are started by the controller, which, under the action of the guide rod and the threaded rod, drive the strip plate to move downwards stably and complete the soil sampling operation. The operation process is simple and improves the effectiveness of the soil sampling device. Attached Figure Description

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a soil sampling device for agricultural technology promotion, including a base plate 1 and an adjusting plate 2. Two fixing blocks 3 are fixedly installed on the top of the base plate 1. A fixing rod 4 is fixedly installed between one side of the outer wall of the two fixing blocks 3. Two rotating blocks 5 are movably sleeved on the outer wall of the fixing rod 4. An electric push rod 6 is fixedly installed on the top of each of the two rotating blocks 5. A connecting block 7 is fixedly installed at the output end of each of the two electric push rods 6. A grooved block 8 is fixedly installed on the bottom of the adjusting plate 2. Two rotating shafts 9 are fixedly installed between the inner walls of the grooved block 8. The inner walls of the two connecting blocks 7 are movably sleeved on the outer walls of the two rotating shafts 9. Two upright plates 10 are fixedly installed on the top of the base plate 1. A rotating rod 11 is fixedly installed between opposite sides of the outer walls of the two upright plates 10. The inner wall of the adjusting plate 2 is movably sleeved on the outer wall of the rotating rod 11.

[0024] The overall effect of Embodiment 1 is as follows: when the base plate 1 is located in the corresponding area for soil sampling, the base plate 1 is first fixed in the corresponding position using external tools. At this time, when the level 12 on the adjusting plate 2 shows that the adjusting plate 2 is not horizontal, the controller 20 starts the two electric push rods 6. Since the rotating blocks 5 installed at the bottom of the two electric push rods 6 are movably sleeved on the fixed rod 4, and the connecting blocks 7 installed at the output end of the two electric push rods 6 are movably sleeved on the two rotating shafts 9 inside the groove block 8, the other end of the adjusting plate 2 is movably sleeved on the rotating rod 11 installed between the two vertical plates 10. Thus, through the extension and retraction of the two electric push rods 6, the two rotating blocks 5 rotate on the fixed rod 4, the two connecting blocks 7 rotate on the rotating shafts 9, and the adjusting plate 2 can rotate on the rotating rod 11, thereby adjusting the angle of the adjusting plate 2 until the level 12 shows that the adjusting plate 2 is in a horizontal state. Then, the sampling device and sampling component 19 will not deviate from the predetermined direction during sampling, making the sampled soil sample representative and improving the accuracy of subsequent soil analysis results.

[0025] Example 2: Figures 2-4 As shown, a level 12 is fixedly installed on the top of the adjusting plate 2. Two concave columns 13 are fixedly installed on the top of the adjusting plate 2. A forward and reverse motor 14 is fixedly installed on the top of one of the concave columns 13. A threaded rod 15 is fixedly installed on the bottom of the forward and reverse motor 14. A strip plate 16 is threadedly connected to the outer wall of the threaded rod 15. A guide rod 17 is fixedly installed between the inner walls of the other concave column 13. The inner wall of the strip plate 16 is movably sleeved on the outer wall of the guide rod 17. A drive motor 18 is fixedly installed on the top of the strip plate 16. A sampling component 19 is fixedly installed on the bottom of the drive motor 18. A controller 20 is fixedly installed on the top of the adjusting plate 2. One side of the outer wall of the controller 20 is electrically connected to the outer walls of the two electric push rods 6, the forward and reverse motor 14, and the drive motor 18.

[0026] The effect achieved by the entire embodiment 2 is that when the adjusting plate 2 is adjusted to a horizontal state, the controller 20 starts the drive motor 18 installed on the strip plate 16, which drives the sampling component 19 to rotate. The sampling component 19 includes a sampling cylinder and a sampling drill bit, which can complete the soil sampling. Then, the controller 20 starts the forward and reverse motor 14, which drives the threaded rod 15 to rotate inside one of the concave columns 13. Since a guide rod 17 is installed inside the other concave column 13, one end of the strip plate 16 is threaded to the threaded rod 15, and the other end is movably sleeved on the guide rod 17. This allows the strip plate 16, the drive motor 18, and the sampling component 19 to move downward and complete the soil sampling, thus improving the practicality of the soil sampling device for agricultural technology promotion.

[0027] Working principle: First, when the soil sampling device and base plate 1 are located in the corresponding soil area and the base plate 1 is fixed there, the controller 20 starts two electric push rods 6, which drive two rotating blocks 5 to rotate on the fixed rod 4, and simultaneously drive two connecting blocks 7 to rotate on two rotating shafts 9 inside the groove block 8. This causes the other end of the adjusting plate 2 to rotate on the fixed rod 4, completing the angle adjustment of the adjusting plate 2 until the level 12 shows that the adjusting plate 2 is in a horizontal state. Then, the controller 20 starts the drive motor 18, which drives the sampling component 19 to rotate. Next, the controller 20 starts the forward and reverse motors 14, which, under the action of the guide rod 17, drive the strip plate 16 to move downward along the guide rod 17 and the threaded rod 15. The sampling component 19 then completes the sampling operation on the corresponding soil. The sampling device and the sampling component 19 will not deviate from the original predetermined direction during sampling, making the sampled soil sample representative and improving the accuracy of subsequent soil analysis results. This improves the practicality of the soil sampling device for agricultural technology promotion.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
