Description

Technical Field

[0001] This application belongs to the technical field of soil sampling equipment, and in particular relates to a soil sampling device for environmental planning. Background Technology

[0002] Environmental planning is the rational spatial and temporal arrangement of human activities and the environment to achieve coordinated development between the environment, economy, and society. Its purpose is to guide various environmental protection activities, rationally allocate pollution reduction amounts according to established goals and measures, constrain polluters' behavior, improve the ecological environment, and prevent resource destruction. The implementation of environmental planning typically requires soil sampling in certain geographical locations.

[0003] Chinese patent CN214952281 U discloses a soil sampler for environmental planning, including a base with a threaded hole in the center of the inner side of the base, in which a sampling tube is installed. A mounting bracket is located above the sampling tube at the upper end of the base, and a motor is mounted on the top of the mounting bracket. A connecting shaft is connected to the lower end of the motor, and the bottom of the connecting shaft is fixedly connected to the top of the sampling tube. The bottom of the sampling tube is provided with several cutting blades, and a baffle is provided at the upper part of the sampling tube. The outer side of the sampling tube is provided with an external thread below the baffle, and the external thread is adapted to the thread in the threaded hole. The sampling tube has a cavity, and a bulldozing component is provided on one side of the cavity.

[0004] Although the aforementioned soil sampler can be used for soil sampling, when sampling soft soil layers using this sampling tube, the soil sample is prone to falling out of the sampling tube when the sampling tube is lifted upwards. This issue needs to be addressed. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a soil sampling device for environmental planning that can sample relatively loose soil layers and ensure the stability of soil sampling at different depths.

[0006] This application provides a soil sampling device for environmental planning, comprising:

[0007] The base is equipped with a mounting bracket and a lifting platform;

[0008] The sampling mechanism is mounted on the base;

[0009] A drill bit, mounted on a sampling mechanism, is provided with external threads;

[0010] The drive motor is installed between the lifting plate and the sampling mechanism;

[0011] The sampling mechanism includes a sampling cylinder, a baffle, and a rotating blade. The side wall of the sampling cylinder is provided with a plurality of sampling slots. The baffle is adapted to the sampling slots. The rotating blade is movably installed in the sampling slots. The rotating blade is provided with a first motor. All rotating blades in the sampling slots are coaxially connected. The drive motor is provided with a threaded rod. The mounting bracket is provided with a mounting part adapted to the threaded rod.

[0012] The mounting frame is installed on the base, and the lifting plate is movably installed on the mounting frame. The sampling mechanism is connected to the lifting plate via a drive motor. The drill bit is installed at the lower end of the sampling plate and has external threads to increase the drilling speed. The sampling device is placed on the ground, with the base against the ground. The drive motor controls the drill bit to rotate and move downwards, and the sampling mechanism moves downwards simultaneously with the drill bit. When the sampling mechanism is inserted into the ground, it stops moving downwards. The sampling slot is opened by controlling the baffle, and then the rotating blade scrapes the soil corresponding to the sampling slot into the sampling slot. The sampling slot is then closed by the baffle. The rotating blade is controlled to rotate by the first motor, and the rotating blades in different sampling slots are coaxially connected and driven by the same first motor. The sampling slots in the sampling cylinder are evenly distributed along its axis, enabling stable sampling at different depths in loose soil. The mounting part is fixedly connected to the mounting frame and connected to the threaded rod via a threaded pair. When the drive motor drives the threaded rod and the sampling mechanism to rotate, the sampling mechanism is raised and lowered between itself and the base.

[0013] Furthermore, the sampling mechanism also includes:

[0014] The teeth connect to the baffle.

[0015] A gear is installed in the sampling cylinder and meshes with its teeth;

[0016] The second motor is connected to the gears;

[0017] The sampling cylinder is provided with a movable groove that is adapted to the baffle.

[0018] The toothed part is installed and connected to the baffle. The toothed part is an arc-shaped rack with its axis being the same as the axis of the sampling cylinder. The gear is driven by a second motor to rotate. The gear replaces the toothed part and the baffle to move, so that the baffle moves in the sliding groove. When the baffle opens the sampling groove, the baffle rotates around the axis of the sampling cylinder and moves into the sliding groove. When the baffle is removed from the sliding groove, the sampling groove is closed. After the baffle closes the sampling groove, the parts located in the movable groove are interconnected. During movement, only one second motor is needed to control all the sampling grooves to open or close.

[0019] Furthermore, the base includes:

[0020] Fixed insertion rod;

[0021] The fasteners are provided in several parts and are movably installed on the side wall of the fixed plug;

[0022] The rotating rod is installed on the fixed insertion rod and is aligned with the axis of the fixed insertion rod;

[0023] The connector is movably connected between the fixed part and the rotating rod.

[0024] Before sampling, the sampling mechanism is first inserted into the ground by a fixed rod to improve the overall stability of the sampling equipment. By rotating the rotating rod, the connecting rod pushes the fixing part outward of the fixed rod, which further improves the connection stability between the fixed rod and the ground after it is inserted into the ground.

[0025] Furthermore, the mounting bracket is provided with a sliding groove, and the lifting plate is provided with a sliding part that is adapted to the sliding groove.

[0026] By using a groove and sliding part in conjunction, the stability of the lifting plate during movement is improved, further enhancing the stability of the drill bit and sampling cylinder during movement.

[0027] Furthermore, the lifting plate is equipped with a handle.

[0028] The handle facilitates the movement and transportation of the sampling equipment; the handle is welded to the lifting plate or connected by fasteners.

[0029] Furthermore, the base is equipped with a foot pedal.

[0030] The pedal is mounted on the base. When the fixing rod is inserted into the ground, the pedal facilitates the quick insertion of the fixing rod into the ground.

[0031] The beneficial effects of this application are:

[0032] 1. The sampling trough is opened by controlling the baffle, and then the soil corresponding to the sampling trough is scraped into the sampling trough by rotating the blade. Then the sampling trough is closed by the baffle. This method can stably sample soil at different depths in soft soil.

[0033] 2. The second motor drives the gear to rotate, and the gear replaces the teeth and moves the baffle, so that the baffle moves in the sliding groove, and the baffle opens or closes the sampling groove.

[0034] 3. When the fixing rod is inserted into the ground, the ground descending fixing part extends out, further improving the connection stability between the fixing rod and the ground after it is inserted into the ground. Attached Figure Description

[0043] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0044] Example 1:

[0045] like Figures 1-4 As shown in the figure, this application provides a soil sampling device for environmental planning, including:

[0046] The base 100 is equipped with a mounting bracket 110 and a lifting plate 120.

[0047] The sampling mechanism 200 is mounted on the base 100;

[0048] A drill bit 300 is mounted on a sampling mechanism 200, and the drill bit 300 is provided with an external thread 310;

[0049] A drive motor 400 is installed between the lifting plate 120 and the sampling mechanism 200;

[0050] The sampling mechanism 200 includes a sampling cylinder 210, a baffle 220, and a rotating blade 230. The side wall of the sampling cylinder 210 is provided with a plurality of sampling slots 240. The baffle 220 is adapted to the sampling slots 240. The rotating blade 230 is movably installed in the sampling slots 240. The rotating blade 230 is provided with a first motor 250. All rotating blades 230 in the sampling slots 240 are coaxially connected. The drive motor 400 is provided with a threaded rod 410. The mounting bracket 110 is provided with a mounting part 111 adapted to the threaded rod 410.

[0051] Mounting bracket 110 is mounted on base 100, and lifting plate 120 is movably mounted on mounting bracket 110. Sampling mechanism 200 is connected to lifting plate 120 via drive motor 400. Drill bit 300 is mounted at the lower end of sampling device, and external thread 310 is provided on drill bit 300 to improve drilling speed. The sampling device is placed on the ground, with base 100 abutting against the ground. Drive motor 400 controls drill bit 300 to rotate and move downwards, and sampling mechanism 200 moves downwards simultaneously with drill bit 300. When sampling mechanism 200 is inserted into the ground, it stops moving downwards. Control baffle 220 opens sampling slot 240, and then rotating blade 230 rotates sampling slot 240. The corresponding soil is scraped into the sampling trough 240, and then the sampling trough 240 is closed by the baffle 220. The rotating blade 230 is controlled to rotate by the first motor 250. The rotating blades 230 located in different sampling troughs 240 are coaxially connected and driven by the same first motor 250. The sampling troughs 240 in the sampling cylinder 210 are evenly distributed along its axial direction, which can stably sample different depths of loose soil. The mounting part 111 is fixedly connected to the mounting frame 110. The mounting part 111 is connected to the threaded rod 410 through the threaded pair. When the drive motor 400 drives the threaded rod 410 and the sampling mechanism 200 to rotate, the sampling mechanism 200 is lifted and lowered between itself and the base 100.

[0052] Furthermore, the sampling mechanism 200 also includes:

[0053] The toothed part 221 is connected to the baffle 220;

[0054] Gear 222 is installed in sampling cylinder 210 and meshes with teeth 221;

[0055] The second motor 223 is connected to the gear 222;

[0056] The sampling cylinder 210 is provided with a movable groove 211 that is adapted to the baffle 220.

[0057] The toothed part 221 is installed and connected to the baffle 220. The toothed part 221 is an arc-shaped rack with its axis being the same as the axis of the sampling cylinder 210. The second motor 223 drives the gear 222 to rotate. The gear 222 moves in place of the toothed part 221 and the baffle 220, so that the baffle 220 moves in the sliding groove. When the baffle 220 opens the sampling groove 240, the baffle 220 rotates around the axis of the sampling cylinder 210 and moves into the sliding groove. When the baffle 220 is removed from the sliding groove, the sampling groove 240 is closed. After the baffle 220 closes the sampling groove 240, the parts located in the movable groove 211 are interconnected. During movement, only one second motor 223 is needed to control all the sampling grooves 240 to open or close.

In addition to the above-mentioned technical features, the mounting frame 110 is provided with a sliding groove 112, and the lifting plate 120 is provided with a sliding part 121 adapted to the sliding groove 112.

[0067] The sliding groove 112, in conjunction with the sliding part 121, improves the stability of the lifting plate 120 during movement, thereby further enhancing the stability of the drill bit 300 and the sampling cylinder 210 during movement.

[0068] Furthermore, the lifting plate 120 is provided with a handle 122.

[0069] The handle 122 facilitates the movement and transportation of the sampling equipment. The handle 122 is welded to the lifting plate 120 or connected by fasteners.
