Description

Technical Field

[0001] This application belongs to the field of soil testing technology, specifically relating to a soil sampling device for testing in plant cultivation areas. Background Technology

[0002] Soil is an important component of agricultural production and the ecological environment. Since the characteristics of field soil and crops are not uniform but change with time and space, precise fertilization and soil management are required in refined agricultural management based on soil quality. This necessitates accurate soil sampling and testing.

[0003] In existing technologies, when testing corn-growing areas, soil samples are first taken by inserting a sampling device into the soil; by adjusting the depth of the sampling device inserted into the soil, soil samples at different depths can be collected.

[0004] The inventors discovered that existing sampling devices can only collect soil samples from a single location at a time. When collecting soil samples from the same area at different depths, the device needs to be repeatedly inserted into the soil holes. However, the process of repeatedly inserting and removing the sampling device will damage the original soil environment, causing technical problems such as inaccurate soil sample collection, which in turn affects the reliability of soil test results. Utility Model Content

[0005] This application provides a soil sampling device for testing in plant cultivation areas, which aims to collect multiple sets of soil samples at different depths in a single operation to ensure the accuracy of soil sample collection and thus guarantee the reliability of subsequent soil testing results.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A soil sampling device for testing plant cultivation areas is provided, comprising:

[0008] Positioning plate, used to move directly above the sampling area;

[0009] A rotating cylinder is disposed on the lower side of the positioning plate, and its axis is parallel to the vertical direction; the rotating cylinder is rotatably connected to the positioning plate in the vertical direction, and the rotating cylinder is driven by a first rotating drive component; the rotating cylinder has an internally hollow structure and has multiple through holes spaced apart in the vertical direction, all of which are connected to the interior of the rotating cylinder.

[0010] Multiple sets of sliding members are inserted one-to-one into multiple through holes, and each set of sliding members includes two sliding members spaced apart along the axial direction of the through hole, so that when the two sliding members move in opposite directions, the two sliding members can extend out from both ends of the through hole respectively; and, a sampling cup with an opening facing the rotating cylinder and used for entering soil samples can be detachably connected to the side of the protruding portion of each sliding member; and

[0011] A synchronous drive assembly is disposed on the rotating drum and is connected to multiple sets of sliding members for transmission, so that the two sliding members corresponding to each set of sliding members move simultaneously toward each other or toward each other.

[0012] In one possible implementation, the synchronization drive component includes:

[0013] Multiple sets of lifting components are disposed inside the rotating drum and correspond one-to-one with multiple sets of sliding components. Each set of lifting components includes two lifting components arranged side by side in the vertical direction between two corresponding sliding components. Each lifting component is slidably connected to the inner wall of the rotating drum in the vertical direction, and each lifting component is fixedly connected with a fixing nut whose axial direction is parallel to the vertical direction. Each lifting component is hinged with two swing arms, and the swing ends of the two swing arms are respectively hinged to the two corresponding sliding components, so that when the two lifting components move towards each other or away from each other, the two sliding components move towards each other or away from each other synchronously.

[0014] Multiple double-ended screws, coaxially arranged in the vertical direction, are all located inside the rotating drum and correspond one-to-one with multiple sets of lifting components. Each double-ended screw has two threaded portions with opposite thread directions, and each of the two threaded portions is threadedly connected to two corresponding fixing nuts. Furthermore, adjacent double-ended screws are connected to synchronize their rotation.

[0015] A transmission rod is disposed inside the rotating drum, its axis is parallel to the vertical direction, and it is rotatably connected to the rotating drum in the vertical direction and is connected to a second rotation drive component.

[0016] The transmission rod is connected to one of the double-ended screws so that when the second rotation drive component drives the transmission rod to rotate, the multiple double-ended screws rotate synchronously, and the two lifting components corresponding to each group of lifting components move towards each other or away from each other.

[0017] In one possible implementation, the upper end of the rotating drum has an opening communicating with its interior, and a cover plate detachably connected to its upper end face to close the opening;

[0018] The transmission rod is coaxially arranged with the double-ended screw, and it passes through the cover plate and extends outward; the second rotation drive component includes:

[0019] The driven gear is coaxially connected to the upper end of the transmission rod; and

[0020] The second rotating motor is fixedly installed on the upper side of the cover plate, and its power output axis is parallel to the vertical direction, and its power output end is coaxially connected to the driving gear that meshes with the driven gear.

[0021] In one possible implementation, the upper and lower ends of the double-ended screw each have a protrusion and a groove suitable for the protrusion to be inserted.

[0022] The lower end of the transmission rod has a mating groove suitable for the protrusion to be inserted, and the inner bottom surface of the rotating cylinder is rotatably connected to a mating piece suitable for being embedded in the groove in the up-down direction.

[0023] In one possible implementation, the outer peripheral wall of the transmission rod is provided with an external thread structure, and a support nut suitable for abutting against the side of the cover plate is threaded onto the transmission rod.

[0024] In one possible implementation, the lower end of the rotating drum adopts a conical structure with the diameter gradually decreasing from top to bottom.

[0025] In one possible implementation, the positioning plate has a reserved hole coaxially arranged with the rotating drum, and a turntable is rotatably connected in the reserved hole. The turntable is connected to the upper end face of the rotating drum through multiple connecting rods. The first rotation driving component is a first rotation motor fixedly arranged on the positioning plate and drivenly connected to the turntable.

[0026] In one possible implementation, both ends of the positioning plate are provided with gripping holes that extend in the vertical direction.

[0027] In one possible implementation, the slider has a receiving groove on its side facing the circumferential direction of the rotating cylinder, suitable for embedding the sampling cup.

[0028] In one possible implementation, the bottom of the receiving groove has a through hole extending to the side of the sliding member facing away from the circumferential direction of the rotating cylinder, and the bottom of the sampling cup is fixedly connected with a positioning screw suitable for insertion into the through hole, and the positioning screw is threaded with an alignment nut suitable for abutting against the sliding member.

[0029] In this embodiment, by moving the positioning plate above the sampling area and applying a downward force to the positioning plate, the rotating cylinder can be inserted into the ground. During this process, the first rotation drive component drives the rotating cylinder to rotate, which reduces the force required for the rotating cylinder to insert into the ground. After the rotating cylinder is inserted into the ground, the synchronous drive component drives multiple sets of sliding parts to move, so that each pair of corresponding sliding parts moves in opposite directions, thereby moving the sampling cup outside the rotating cylinder. In this state, the first rotation drive component drives the rotating cylinder to rotate, so that the sampling cup rotates synchronously and the soil sample enters the sampling cup. Finally, the synchronous drive component drives each pair of corresponding sliding parts to move towards each other until the sampling cup moves into the rotating cylinder, and pulls the positioning plate upward to pull the rotating cylinder out of the ground, thus completing the soil sample collection process.

[0030] The soil sampling device for plant planting area testing provided in this embodiment, compared with the prior art, can collect multiple soil samples at different depths in a single sampling by using multiple sampling cups, ensuring the accuracy of soil sample collection and thus guaranteeing the reliability of subsequent soil testing results.

Therefore, they should not be construed as limitations on this application.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] Please refer to the following: Figures 1 to 10 The soil sampling device for plant planting area testing provided in this application will now be described. The soil sampling device for plant planting area testing proposed in this application includes a positioning plate 1, a rotating cylinder 2, multiple sets of sliding parts 3, and a synchronous drive assembly 4.

[0048] The positioning plate 1 is used to move to the top of the sampling area; specifically, the positioning plate 1 can be moved by manual grasping, or it can be slidably connected to the trolley in the vertical direction to realize the movement of the positioning plate 1.

[0049] The rotating drum 2 is located on the lower side of the positioning plate 1, and its axis is parallel to the vertical direction.

[0050] The rotating drum 2 is rotatably connected to the positioning plate 1 in the vertical direction, and the rotating drum 2 is connected to the first rotation drive component 21. The first rotation drive component 21 enables the rotating drum 2 to rotate relative to the positioning plate 1, so that the rotating drum 2 can drill into the ground and ensure that the rotating drum 2 can move to the corresponding depth of the sampling area.

[0051] The rotating cylinder 2 has an internally hollow structure and multiple through holes 22 that are spaced apart in the vertical direction and communicate with the interior of the rotating cylinder 2.

[0052] Multiple sets of sliding members 3 are inserted into multiple through holes 22 in a one-to-one correspondence, and each set of sliding members 3 includes two sliding members 3 spaced apart along the axial direction of the through hole 22.

[0053] When the two sliders 3 move in opposite directions, the two sliders 3 can extend from both ends of the through hole 22 respectively.

[0054] When the two sliding members 3 move toward each other, the two sliding members 3 can be housed inside the through hole 22 to avoid affecting the process of inserting the rotating cylinder 2 into the ground.

[0055] Each sliding member 3 has a detachable sampling cup 5 with an opening facing the circumferential direction of the rotating cylinder 2, which is used to allow soil samples to enter. This allows the soil sample to enter the sampling cup 5 by rotating the rotating cylinder 2 when the rotating cylinder 2 is inserted into the ground and the sampling cup 5 extends to the outside of the rotating cylinder 2.

[0056] The synchronous drive component 4 is mounted on the rotating drum 2 and is connected to multiple sets of sliding members 3 for transmission, so that the two sliding members 3 corresponding to each set of sliding members 3 can move towards each other or away from each other at the same time.

[0057] In this embodiment, by moving the positioning plate 1 above the sampling area and applying a downward force to the positioning plate 1, the rotating cylinder 2 can be inserted into the ground. During this process, the first rotation drive component 21 drives the rotating cylinder 2 to rotate, thereby reducing the force required for the rotating cylinder 2 to insert into the ground. After the rotating cylinder 2 is inserted into the ground, the synchronous drive component 4 drives multiple sets of sliding members 3 to move, so that each pair of corresponding sliding members 3 moves in opposite directions, thereby moving the sampling cup 5 outside the rotating cylinder 2. In this state, the first rotation drive component 21 drives the rotating cylinder 2 to rotate, so that the sampling cup 5 rotates synchronously and the soil sample enters the sampling cup 5. Finally, the synchronous drive component 4 drives each pair of corresponding sliding members 3 to move towards each other until the sampling cup 5 moves into the rotating cylinder 2, and pulls the positioning plate 1 upward, so that the rotating cylinder 2 is pulled out of the ground, thus completing the soil sample collection process.

[0058] The soil sampling device for plant planting area testing provided in this embodiment, compared with the prior art, can collect multiple soil samples at different depths in a single sampling cup 5, ensuring the accuracy of soil sample collection and thus guaranteeing the reliability of subsequent soil testing results.

[0059] In some embodiments, such as Figure 3 and Figure 6 As shown, the synchronous drive assembly 4 includes multiple sets of lifting components 41, multiple double-ended screws 42, and transmission rods 43.

[0060] Multiple sets of lifting components 41 are all installed inside the rotating drum 2, and correspond one-to-one with multiple sets of sliding components 3.

[0061] Each set of lifting components 41 includes two lifting components 41 arranged side by side in the vertical direction between the corresponding two sliding components 3. Each lifting component 41 is slidably connected to the inner wall of the rotating drum 2 in the vertical direction, and each lifting component 41 is fixedly connected with a fixing nut 411 whose axial direction is parallel to the vertical direction.

[0062] Furthermore, each lifting component 41 is hinged with two swing arms 412, and the swing ends of the two swing arms 412 are respectively hinged to the corresponding two sliding components 3, so that when the two lifting components 41 move towards each other or away from each other, the two sliding components 3 move towards each other or away from each other synchronously.

[0063] Multiple double-ended screws 42 are coaxially arranged in the vertical direction, and all the double-ended screws 42 are located inside the rotating drum 2, corresponding one-to-one with multiple sets of lifting components 41.

[0067] In some embodiments, such as Figures 3 to 5 As shown, the upper end of the rotating drum 2 has an opening communicating with its interior, and a cover plate 23 that is detachably connected to its upper end face and closes the opening.

[0072] The lower end of the transmission rod 43 has a mating groove 431 suitable for the protrusion 421 to be inserted. The inner bottom surface of the rotating drum 2 is rotatably connected to a mating piece 24 suitable for being inserted into the groove 422 in the up and down direction, so as to realize the synchronous rotation of the transmission rod 43 and the double-ended screw 42, and the rotational connection of the rotating drum 2 and the double-ended screw 42 respectively.

[0073] In some embodiments, such as Figure 3 and Figure 5 As shown, the outer peripheral wall of the transmission rod 43 is provided with an external thread structure, and the transmission rod 43 is threadedly connected with a support nut 432 suitable for abutting against the upper side of the cover plate 23, so as to enhance the structural strength between the transmission rod 43 and the rotating drum 2.

[0074] In some embodiments, such as Figures 1 to 3 As shown, the lower end of the rotating cylinder 2 adopts a conical structure with the cylinder diameter gradually decreasing from top to bottom, so as to facilitate its insertion into the ground.

[0075] In some embodiments, such as Figure 4 As shown, the positioning plate 1 has a reserved hole 11 coaxially arranged with the rotating drum 2, and a turntable 12 is rotatably connected in the reserved hole 11.

[0076] The turntable 12 is connected to the upper end face of the rotating drum 2 through multiple connecting rods 121; based on this, the aforementioned first rotation drive component 21 is a first rotation motor that is fixedly mounted on the positioning plate 1 and is connected to the turntable 12 in a transmission manner. The first rotation motor is fixed on the upper side of the positioning plate 1 by a bracket, and its power output end faces downward and is coaxially connected to the turntable 12 in a transmission manner.

[0077] In some embodiments, such as Figure 1 As shown, both ends of the positioning plate 1 are provided with gripping holes 13 that run through the vertical direction to facilitate manual gripping.

[0078] In some embodiments, such as Figure 7 As shown, the sliding member 3 has a receiving groove 31 on the side facing the rotating cylinder 2 in the circumferential direction, which is suitable for the sampling cup 5 to be inserted; by inserting the sampling cup 5 into the receiving groove 31, the sliding member 3 can be stored in the through hole 22.

[0079] In some embodiments, such as Figure 7 As shown, the bottom of the receiving groove 31 is provided with a through hole 32 that extends through to the side of the sliding member 3 facing away from the rotating cylinder 2. The bottom of the sampling cup 5 is fixedly connected with a positioning screw 51 suitable for insertion into the through hole 32, and the positioning screw 51 is threadedly connected with an alignment nut 52 suitable for abutting against the sliding member 3.
