Abstract

This utility model discloses a rapid soil sampling device for arable land quality testing, including a base. A mounting frame is fixedly installed on the top of the base. A collecting cylinder is mounted on the top of the mounting frame via a pushing mechanism. A collecting groove is formed on the surface of the collecting cylinder. A drill bit is fixedly installed at the bottom of the collecting cylinder. A connecting frame is fixedly installed at the bottom of the base. A worm gear is mounted on one side of the connecting frame via a rotating mechanism. A worm wheel is meshed on the surface of the worm gear. The entire device can be moved to a designated soil sampling position using casters. The rotating mechanism drives two sets of worm gears to rotate, which in turn drives two sets of worm wheels to rotate. This, in turn, drives two sets of pointed cones to descend via a lifting mechanism.

This allows four sets of pointed cones to be inserted into the ground, thus supporting the entire device and improving its stability.

Description

Technical Field

[0001] This utility model relates to the field of soil sampling device technology, and in particular to a rapid soil sampling device for testing the quality of cultivated land. Background Technology

[0002] Farmland quality testing refers to the process of systematically monitoring, analyzing, and evaluating the physical and chemical properties of farmland soil, environmental conditions, and the status of engineering facilities. Its core objective is to scientifically assess the productivity, health status, and sustainable utilization potential of farmland, providing a scientific basis for agricultural production management, farmland protection, land consolidation, and policy formulation. Soil sampling is typically required when conducting farmland quality testing.

[0003] When using a soil sampling device, the device is usually moved to a designated location using casters, and then the collection cylinder and drill bit are used to collect the soil. However, after the entire device is moved using casters, no support mechanism is set up to support it. This can cause the device to shift during the soil sampling process, affecting the use of the collection cylinder and drill bit. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid soil sampling device for testing arable land quality, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid soil sampling device for arable land quality testing includes a base, a mounting frame fixedly installed on the top of the base, a collecting cylinder mounted on the top of the mounting frame via a pushing mechanism, a collecting groove formed on the surface of the collecting cylinder, a drill bit fixedly installed on the bottom of the collecting cylinder, a connecting frame fixedly installed on the bottom of the base, a worm gear mounted on one side of the connecting frame via a rotating mechanism, a worm wheel meshing with the surface of the worm gear, a lifting plate mounted on the inner wall of the worm wheel via a lifting mechanism, a connecting column fixedly installed on the bottom of the lifting plate, a pointed cone fixedly installed at one end of the connecting column, and a limit mechanism provided on the inner wall of the connecting frame.

[0007] Preferably, the pushing mechanism includes an electric push rod fixedly installed on the top of the mounting frame, and a push plate is fixedly installed on the output end of the electric push rod. The bottom of the push plate and the top of the collecting cylinder are fixedly installed.

[0008] Preferably, the rotating mechanism includes a motor fixedly installed on one side of the connecting frame, and a rotating rod fixedly installed at the output end of the motor, wherein the surface of the rotating rod and the inner wall of the worm gear are fixedly installed.

[0009] Preferably, the lifting mechanism includes a lead screw fixedly installed on the inner wall of the worm gear, and a lifting block is threaded onto the surface of the lead screw. One side of the lifting block and one side of the lifting plate are fixedly installed.

[0010] Preferably, the limiting mechanism includes a connecting block fixedly installed on the inner wall of the connecting frame, and a limiting groove is formed on one side of the connecting block, the inner wall of the limiting groove being in contact with the surface of the lifting block.

[0011] Preferably, the bottom of the connecting frame is provided with casters, and the number of casters is four sets arranged in an array.

[0012] Preferably, there are two sets of rotating rods and four sets of worm gears, worm wheels, and lead screws.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This rapid soil sampling device for farmland quality testing can be moved to a designated soil sampling location via casters. A rotating mechanism drives two sets of worm gears to rotate, which in turn drives two sets of worm wheels. This, in turn, lowers two sets of pointed cones via a lifting mechanism. Simultaneously, the rotating mechanism drives another set of rotating rods via a synchronous belt, which in turn lowers another two sets of pointed cones. This allows all four sets of pointed cones to be inserted into the ground, providing support and improving overall stability. A pushing mechanism drives a drill bit to create a hole in the soil, from which soil can be collected using a collection cylinder. After soil collection, four sets of lifting mechanisms raise the four sets of pointed cones, which are then supported by the casters, facilitating movement and achieving stable support. The device has a simple structure and is easy to use. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Refer to Figure 1-4 This utility model provides a technical solution: a rapid soil sampling device for testing arable land quality, comprising a base 1, a mounting frame 2 fixedly installed on the top of the base 1, a collection cylinder 5 mounted on the top of the mounting frame 2 via a pushing mechanism, the pushing mechanism including an electric push rod 3 fixedly installed on the top of the mounting frame 2, a push plate 4 fixedly installed at the output end of the electric push rod 3, the bottom of the push plate 4 and the top of the collection cylinder 5 being fixedly installed to facilitate lifting and lowering the collection cylinder 5, a collection groove 6 being formed on the surface of the collection cylinder 5, a drill bit 7 fixedly installed at the bottom of the collection cylinder 5, a connecting frame 8 fixedly installed at the bottom of the base 1, and four sets of universal wheels 20 arranged in an array at the bottom of the connecting frame 8 to facilitate movement of the entire device. A worm gear 11 is mounted on one side of the connecting frame 8 via a rotating mechanism. The rotating mechanism includes a motor 9 fixedly mounted on one side of the connecting frame 8. A rotating rod 10 is fixedly mounted on the output end of the motor 9. The surface of the rotating rod 10 and the inner wall of the worm gear 11 are fixedly mounted to facilitate the rotation of the worm gear 11. A worm wheel 12 is meshed on the surface of the worm gear 11. A lifting plate 15 is mounted on the inner wall of the worm wheel 12 via a lifting mechanism. The lifting mechanism includes a lead screw 13 fixedly mounted on the inner wall of the worm wheel 12. A lifting block 14 is threaded onto the surface of the lead screw 13. One side of the lifting block 14 and one side of the lifting plate 15 are fixedly mounted to facilitate the lifting of the lifting plate 15. A connecting column 16 is fixedly mounted on the bottom of the lifting plate 15. A pointed cone 17 is fixedly mounted on one end of the connecting column 16.

[0021] Specifically, the inner wall of the connecting frame 8 is provided with a limiting mechanism, which includes a connecting block 18 fixedly installed on the inner wall of the connecting frame 8. A limiting groove 19 is opened on one side of the connecting block 18. The inner wall of the limiting groove 19 is in contact with the surface of the lifting block 14 to limit the lifting block 14, making the lifting of the lifting block 14 more stable. There are two sets of rotating rods 10, and four sets of worm gears 11, worm wheels 12, and lead screws 13. The whole can be moved to the designated soil extraction position by means of casters 20. The rotating mechanism drives the two sets of worm gears 11 to rotate, and the worm gears 11 drive the two sets of worm wheels 12 to rotate, which in turn drives the two sets of lead screws 13 to rotate by means of the lifting mechanism. Cone 17 descends, while the rotating mechanism drives another set of rotating rods 10 to rotate via a synchronous belt. This, in turn, drives two more sets of pointed cones 17 to descend, inserting all four sets of pointed cones 17 into the ground to support the entire structure and improve its stability. The pushing mechanism drives the drill bit 7 to drill a hole in the soil, allowing soil to be collected through the collection cylinder 5. After soil collection, the four sets of lifting mechanisms drive the four sets of pointed cones 17 to rise, supporting the entire structure via casters 20. This facilitates movement of the entire structure and achieves the goal of providing stable support. The structure is simple and easy to use.

[0022] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0023] In use: When using this rapid soil sampling device for farmland quality testing, the entire unit can be moved to the designated soil sampling position using the casters 20. The motor 9 drives the rotating rod 10 to rotate, which in turn drives two sets of worm gears 11. The worm gears 11 drive two sets of worm wheels 12, which in turn drive two sets of lead screws 13. The lead screws 13 then drive two sets of lifting blocks 14 to descend, which in turn drive two sets of lifting plates 15 to descend. The lifting plates 15 then drive two sets of connecting columns 16 to descend, and the connecting columns 16 drive two sets of pointed cones 17 to descend. Simultaneously, the rotating rod 10 drives another set of rotating rods 10 via a synchronous belt, which in turn drives the other two sets of pointed cones 17. The cone 17 descends, inserting four sets of pointed cones 17 into the ground to support the entire structure and improve its stability. The electric push rod 3 drives the push plate 4 to descend, which in turn drives the collection cylinder 5 to descend. The collection cylinder 5 then drives the drill bit 7 to descend, allowing the drill bit 7 to drill a hole in the soil and collect soil through the collection cylinder 5. After soil collection, the electric push rod 3 drives the drill bit 7 to rise, which in turn drives four sets of lifting blocks 14 to rise. The lifting blocks 14 then drive the four sets of pointed cones 17 to rise, providing support for the entire structure via the casters 20. This facilitates movement of the entire structure and achieves the goal of providing stable support. The structure is simple and easy to use.
