Description

Technical Field

[0001] This utility model relates to the field of ecological environment monitoring technology, specifically a soil sampling device for ecological environment monitoring. Background Technology

[0002] Soil sampling is a crucial step in obtaining soil environmental data during ecological and environmental monitoring. By collecting and analyzing soil samples from different regions, we can effectively understand the pollution status, nutrient content, and physicochemical properties of the soil, providing important information for ecological and environmental protection, land resource utilization, and the formulation of environmental governance plans.

[0003] The prior art patent document CN216717849U provides a soil sampling device for ecological environment testing. The device starts a second drive motor to drive the drilling shaft to rotate, and at the same time starts a first drive motor to drive the active rotating screw and the driven rotating screw to rotate. By using the lowering cooperation of the lifting plate, the drilling shaft and the drill bit drill the soil to collect samples. After drilling is completed, the first drive motor is reversed to raise the lifting plate to complete the sampling operation.

[0004] The aforementioned existing technology can achieve basic soil drilling and sampling functions, but it still has obvious shortcomings in practical applications. The device does not have an effective automatic soil sample feeding structure. After sampling, the soil sample remains inside the drill bit and needs to be cleaned manually, which increases the operation steps and workload. At the same time, it lacks a convenient sample collection mechanism, which affects the sample collection efficiency. Therefore, we need a soil sampling device for ecological environment monitoring. Utility Model Content

[0005] The purpose of this invention is to provide a soil sampling device for ecological environment testing, so as to solve the problem mentioned in the background art of not having an effective automatic soil sample feeding structure.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a soil sampling device for ecological environment testing, including a shell, a first motor fixedly installed on the top of the shell, and a lead screw fixedly connected to the output shaft of the first motor through a coupling, a lifting plate threadedly connected to the outer wall of the lead screw, and a second motor fixedly installed on the top of the lifting plate, a rotating rod fixedly connected to the output shaft of the second motor through a coupling, and a drill bit fixedly connected to one end of the rotating rod, a feeding assembly provided on the outer wall of the drill bit, and a collecting assembly provided on one side of the shell; The feeding assembly includes a through hole, a mounting cylinder is fixedly connected to the top of the drill bit, and a spring is fixedly connected to the inner wall of the mounting cylinder.

A second long rod is fixedly connected to the bottom of the top plate, and a feeding round rod is fixedly connected to the bottom of the second long rod. A mounting bracket is fixedly connected to the inner wall of the outer shell. The collection component includes a slot, an elongated groove is provided on the inner bottom of the outer shell, a first magnet is fixedly connected to one side of the outer shell, a collection box is slidably connected to the inner wall of the slot, and a roller is provided at the bottom of the collection box. A fixing plate is fixedly connected to the outer wall of the collection box, and a second magnet is fixedly connected to the inner wall of the fixing plate. A fixing handle is fixedly connected to the outer wall of the fixing plate.

[0007] Preferably, the inner wall of the drill bit has a through hole, and the through hole has a circular structure.

[0008] Preferably, one end of the feeding rod extends into the through hole, and the outer wall of the feeding rod is in close contact with the inner wall of the through hole.

[0009] Preferably, the inner wall of the mounting cylinder matches the outer wall of the sliding block, and the sliding block can slide along the inner wall of the mounting cylinder.

[0012] Preferably, the shape and size of the first magnet match the shape and size of the second magnet, and the outer walls of the first magnet and the outer walls of the second magnet are fixedly connected by magnetic attraction.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: First, when the drill bit completes sampling and rises, the rubber block at the top of the top plate contacts and is squeezed against the bottom of the mounting frame, pushing the first and second long rods downward. The second long rod drives the feeding rod to move synchronously within the through hole of the drill bit, which can push out the soil sample from the through hole.

[0017] 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.

[0018] like Figures 1-4 As shown, a soil sampling device for ecological environment testing includes a housing 1. A first motor 2 is fixedly installed on the top of the housing 1, and the output shaft of the first motor 2 is fixedly connected to a lead screw 3 via a coupling. A lifting plate 4 is threadedly connected to the outer wall of the lead screw 3, and a second motor 5 is fixedly installed on the top of the lifting plate 4. A rotating rod 6 is fixedly connected to the output shaft of the second motor 5 via a coupling, and a drill bit 7 is fixedly connected to one end of the rotating rod 6. A feeding assembly 8 is provided on the outer wall of the drill bit 7, and a collection assembly 9 is provided on one side of the housing 1. The feeding assembly 8 includes a through hole 801, a mounting cylinder 802 is fixedly connected to the top of the drill bit 7, a spring 803 is fixedly connected to the inner wall of the mounting cylinder 802, a sliding block 804 is fixedly connected to the top of the spring 803, a first long rod 805 is fixedly connected to the top of the sliding block 804, a top plate 806 is fixedly connected to the top of the first long rod 805, a rubber block 807 is fixedly connected to the top of the top plate 806, a second long rod 808 is fixedly connected to the bottom of the top plate 806, and a feeding round rod 809 is fixedly connected to the bottom of the second long rod 808. A mounting bracket 810 is fixedly connected to the inner wall of the outer shell 1. The collection component 9 includes a slot 901, an elongated groove 902 is provided on the inner bottom of the outer shell 1, a first magnet 903 is fixedly connected to one side of the outer shell 1, a collection box 904 is slidably connected to the inner wall of the slot 901, and a roller 905 is provided at the bottom of the collection box 904. A fixing plate 906 is fixedly connected to the outer wall of the collection box 904, and a second magnet 907 is fixedly connected to the inner wall of the fixing plate 906. A fixing handle 908 is fixedly connected to the outer wall of the fixing plate 906.

[0019] Through the above technical solution, when the drill bit 7 completes sampling and rises, the rubber block 807 on the top of the top plate 806 contacts and is squeezed against the bottom of the mounting frame 810, pushing the first long rod 805 and the second long rod 808 downward. The second long rod 808 drives the feeding rod 809 to move synchronously within the through hole 801 of the drill bit 7, which can push out the soil sample from the through hole 801. The soil sample falls into the collection box 904 for collection, realizing automatic soil sample feeding, eliminating the manual feeding step and reducing labor intensity. The collection box 904 can easily slide along the long groove 902 and slot 901 through multiple rollers 905 set at the bottom, which is convenient for quick pushing in or pulling out. The operation is simple and convenient. The first magnet 903 on one side of the outer shell 1 and the second magnet 907 on the outer wall fixing plate 906 of the collection box 904 are magnetically attracted and fixed to each other, effectively preventing the collection box 904 from shaking or displacing during the operation or movement of the device, thus enhancing stability.

[0020] Specifically, the inner wall of the drill bit 7 has a through hole 801, and the through hole 801 has a circular structure.

[0021] The above technical solution provides a stable space for soil samples by opening a circular through hole 801, ensuring that the soil can smoothly enter the drill bit 7 during the sampling process. At the same time, the circular structure is easy to cooperate with the feeding rod 809, reducing soil residue during feeding and improving the integrity of sample collection.

[0022] Specifically, one end of the feeding rod 809 extends into the through hole 801, and the outer wall of the feeding rod 809 is in close contact with the inner wall of the through hole 801.

[0023] Through the above technical solution, the tightly fitting structural design ensures that the feeding rod 809 effectively pushes the soil sample in the through hole 801 during the movement, avoiding soil residue in the gaps, ensuring the thoroughness of automatic feeding, and reducing the need for manual cleaning; the inner wall of the mounting frame 810 is provided with a through groove, which is circular in structure, to facilitate the passage of the rotating rod 6. At the same time, no matter how the drill bit 7 rotates, when the drill bit 7 stops rotating and rises, the mounting frame 810 can effectively contact the rubber block 807 on the top plate 806. The rubber block 807 can buffer the impact force of collision and reduce the wear of parts.

[0024] Specifically, the inner wall of the mounting cylinder 802 matches the outer wall of the sliding block 804, and the sliding block 804 can slide along the inner wall of the mounting cylinder 802.

[0025] The above technical solution makes the sliding block 804 slide more smoothly in the mounting cylinder 802, avoiding jamming.

[0026] Specifically, one end of the first long rod 805 passes through the mounting cylinder 802 and is fixedly connected to the top plate 806, and the outer wall of the drill bit 7 is provided with a spiral ring cutter.

[0027] The above technical solution enables the first long rod 805 to drive the sliding block 804 to move stably within the mounting cylinder 802 when it moves; while the spiral ring cutter can easily cut into the soil when the drill bit 7 rotates, improving sampling efficiency.

[0028] Specifically, there are multiple rollers 905, and the multiple rollers 905 are evenly spaced at the bottom of the collection box 904.

[0029] Through the above technical solution, multiple equally spaced rollers 905 can distribute the weight of the collection box 904, reduce the friction during sliding, and make it easier to push and pull the collection box 904. At the same time, the equally spaced setting ensures the stability of the sliding process and prevents the collection box 904 from tilting.

[0030] Specifically, the shape and size of the first magnet 903 match the shape and size of the second magnet 907, and the outer wall of the first magnet 903 and the outer wall of the second magnet 907 are fixedly connected by magnetic attraction.

[0031] Through the above technical solution, the shape and size of the first magnet 903 and the second magnet 907 are matched to ensure full contact of the magnetic attraction surfaces, which enhances the fixing effect. The magnetic connection method can achieve quick fixing and separation of the collection box 904 without complicated operation, which improves the convenience of sample collection.

[0032] In use, the operator first pulls the fixing plate 906 using the fixing handle 908 to pull the collection box 904 out of the slot 901 in the outer shell 1. The movement of the collection box 904 causes multiple rollers 905 to roll, reducing friction and making it easy to pull out. When sampling soil, the first motor 2 drives the lead screw 3 to rotate, causing the lifting plate 4 to move down and extend the drill bit 7 out of the bottom of the outer shell 1. The second motor 5 drives the rotating rod 6 to rotate, thereby rotating the drill bit 7. The rotating drill bit 7 moves down to drill into the soil for sampling. After sampling, the first motor 2 moves the drill bit 7 up and stops it. Then, the collection box 904 is inserted into the slot 901 for installation. The first motor 2 moves the drill bit 7 up again, and the rubber block 807 on the top plate 806 contacts the bottom of the mounting bracket 810 and is subjected to pressure. During the compression, the top plate 806 pushes the first long rod 805 and the second long rod 808 downwards. The first long rod 805 drives the sliding block 804 to slide along the inner wall of the mounting cylinder 802 and compress the spring 803. The second long rod 808 drives the feeding rod 809 to move downwards synchronously in the through hole 801, completely pushing out the soil sample in the through hole 801. The soil sample pushed out of the through hole 801 falls naturally into the collection box 904 at the bottom of the outer shell 1. The operator pulls out the collection box 904 to remove the soil sample. When the drill bit 7 performs the next sampling, the spring 803 releases its elastic potential energy, pushing the sliding block 804, the first long rod 805, the top plate 806 and the feeding rod 809 to reset, preparing for the subsequent sampling operation. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
