Description

Technical Field

[0001] This utility model relates to the field of soil and water sample collection technology, specifically a soil and water sample collection device. Background Technology

[0002] Soil and water sample collection is an important task in fields such as environmental monitoring, agricultural research, and geological exploration. Ensuring the representativeness and accuracy of the samples is crucial. The sampling process mainly relies on drilling into the soil.

[0003] For example, the patent application number published on the China Patent Network is 201821810159.X, and the patent name is: A soil sampling device for soil fertility testing. It includes a support plate and a sampling tube. The sampling tube includes an outer tube body with an integrally formed thread in the middle. External soil sampling windows are evenly distributed at the lower end of the outer wall of the outer tube body. A handle is welded to the upper end of the outer wall of the outer tube body, and a soil-opening cone is fixedly connected to the lower end of the outer tube body. A soil storage cavity is opened on the lower side of the inner cavity of the outer tube body. The four-way external soil sampling windows allow for sample collection even when one or two sampling windows are blocked by stones or other debris. Samples are collected at different depths while the sampling tube is being screwed in, making the samples more uniform. The total sampling depth can be adjusted by changing the sampling tube to meet different needs. After the samples are brought back to the laboratory for testing, scientific fertilizers can be applied according to the soil conditions to improve planting efficiency and produce more crops from limited land.

[0004] However, the drill bit of existing sampling equipment is quite sharp, and its direct exposure to the outside can easily scratch users during transport, seriously affecting the safety of the sampling equipment.

[0005] Therefore, the design and modification of the soil and water sample collection device are necessary. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a soil and water sample collection device that improves the safety of sampling equipment. It solves the problem that the drill bit of existing sampling equipment is too sharp and directly exposed to the outside, which can easily scratch users during the process of carrying the equipment, seriously affecting the safety of the sampling equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil and water sample collection device, comprising a column; A sleeve fitted onto the surface of the column; A drilling auger blade is fixedly connected to the surface of the casing. A rotating wheel fitted onto the surface of the column is fixedly connected to the top of the casing. A bracket is fixedly connected to the surface of the column. A shaft is movably connected inside the bracket via bearings. A swing arm is fixedly connected to both sides of the shaft. A shielding petal is fixedly connected to the side of the swing arm away from the shaft. Several shielding petals are evenly arranged around the surface of the drilling auger blade and shield it. An opening and closing structure is provided on the surface of the column, which can simultaneously control the opening of multiple shielding petals.

[0008] As a preferred embodiment of this utility model, the opening and closing structure includes sleeve plates fixedly connected to both sides of the shaft, a wheel disk is sleeved on the surface of the column, an extension rod is fixedly connected to the bottom of the wheel disk, the side of the extension rod away from the wheel disk extends to the outside of the sleeve plate, and a push rod located inside the sleeve plate is fixedly connected to the side of the extension rod away from the wheel disk, and the push rod and the sleeve plate are slidably connected.

[0009] As a preferred embodiment of this invention, the surface of the column is threaded with a threaded sleeve, which is located at the top of the wheel. The threaded sleeve can compress the wheel as it descends through the threads.

[0010] As a preferred embodiment of this utility model, the column is provided with support legs on all four sides, and the side of the support legs away from the column extends to the periphery of the drilling auger blade through the inner side of the shielding petal.

[0011] In a preferred embodiment of this invention, a gear located inside the sleeve is fixedly connected to the surface of the shaft, and a toothed plate located inside the gear is fixedly connected to the outer side of the support leg, with the toothed plate meshing with the gear.

[0012] As a preferred embodiment of the present invention, the surface of the shielding petal is provided with an opening, and the side of the support leg away from the toothed plate extends into the interior of the opening and can slide inside the opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model completely covers the drilling auger blade by setting multiple shielding petals, which avoids scratching the user when carrying it. When the shielding petals are closed, they wrap around the drill bit, reducing the size of the device and making it easy to carry. At the same time, the opening and closing structure enables synchronous control of multiple shielding petals, eliminating the need for manual adjustment one by one.

[0014] 2. This utility model ensures that all blocking petals open or close synchronously by cooperating with the push rod and the sleeve plate, avoiding jamming. It uses a single push rod to drive multiple sets of components, reducing the complexity of the transmission structure and lowering the failure rate.

[0015] 3. This utility model uses a screw sleeve to lock the wheel with threads, preventing the blocking flap from closing accidentally during sampling. The wheel can be locked or released simply by rotating the screw sleeve, without the need for additional tools.

[0016] 4. This utility model forms a triangular support by extending the outriggers and touching the ground, which prevents the device from tilting during drilling. When the outriggers are closed, they retract the inner opening of the shielding flap, maintaining the overall compactness of the device.

[0017] 5. This utility model achieves synchronous movement of the outriggers and the shielding flaps through the meshing of gears and toothed plates, ensuring mechanical coordination. At the same time, the gear transmission converts rotational motion into linear motion, reducing the resistance to outrigger deployment.

[0018] 6. This utility model provides a sliding path for the outriggers through an opening design, avoiding interference between components. The opening is only exposed when the outriggers are extended, and keeps the drill bit completely covered when closed. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a soil and water sample collection device, including a column 1; Sleeve 2 is fitted onto the surface of column 1; A drilling auger blade 3 is fixedly connected to the surface of the casing 2. A rotating wheel 4, which is sleeved on the surface of the column 1, is fixedly connected to the top of the casing 2. A bracket 5 is fixedly connected to the surface of the column 1. A shaft 6 is movably connected inside the bracket 5 through a bearing. A swing arm 7 is fixedly connected to both sides of the shaft 6. A shielding petal 8 is fixedly connected to the side of the swing arm 7 away from the shaft 6. There are several shielding petals 8, which are evenly wrapped around the surface of the drilling auger blade 3 and shield the drilling auger blade 3. An opening and closing structure 9 is provided on the surface of the column 1. The opening and closing structure 9 can control the opening of multiple shielding petals 8 at the same time.

[0023] refer to Figure 2 The opening and closing structure 9 includes a sleeve plate 10 fixedly connected to both sides of the shaft 6. A wheel 11 is sleeved on the surface of the column 1. An extension rod 12 is fixedly connected to the bottom of the wheel 11. The side of the extension rod 12 away from the wheel 11 extends to the outside of the sleeve plate 10. A push rod 13 located inside the sleeve plate 10 is fixedly connected to the side of the extension rod 12 away from the wheel 11. The push rod 13 and the sleeve plate 10 are slidably connected.

[0024] As a technical optimization of this utility model, the push rod 13 cooperates with the sleeve plate 10 to ensure that all blocking petals 8 open or close synchronously, avoiding jamming. The single push rod 13 drives multiple sets of components, reducing the complexity of the transmission structure and lowering the failure rate.

[0025] refer to Figure 1 The surface of the column 1 is threaded with a screw sleeve 14, which is located on the top of the wheel 11. The screw sleeve 14 can squeeze the wheel 11 during the process of descending through the threads.

[0026] As a technical optimization of this utility model, the screw sleeve 14 is used to lock the wheel 11 with threads to prevent the blocking petal 8 from closing accidentally during the sampling process, so that the wheel 11 can be locked or released by simply rotating the screw sleeve 14 without the need for additional tools.

[0027] refer to Figure 2 Support legs 15 are provided around the column 1. The side of the support legs 15 away from the column 1 extends to the periphery of the drilling auger blade 3 through the inner side of the shielding petal 8.

[0028] As a technical optimization of this utility model, the outrigger 15 forms a triangular support when it is deployed and touches the ground, which prevents the device from tilting during drilling. When the outrigger 15 is closed, it retracts the inner opening 18 of the shielding petal 8 to maintain the overall compactness of the device.

[0029] refer to Figure 4 A gear 16 located inside the sleeve 10 is fixedly connected to the surface of the shaft 6, and a toothed plate 17 located inside the gear 16 is fixedly connected to the outer side of the support leg 15. The toothed plate 17 and the gear 16 mesh with each other.

[0030] As a technical optimization of this utility model, the gear 16 meshes with the toothed plate 17 to achieve synchronous movement of the support leg 15 and the shielding petal 8, ensuring mechanical coordination. At the same time, the gear 16 transmission converts the rotational motion into linear motion, reducing the resistance to the deployment of the support leg 15.

[0031] refer to Figure 1 The surface of the shielding petal 8 has an opening 18, and the side of the support leg 15 away from the toothed plate 17 extends into the interior of the opening 18 and can slide inside the opening 18.

[0032] As a technical optimization of this utility model, the opening 18 is designed to provide a sliding path for the support leg 15, avoiding interference between components. The opening 18 is only exposed when the support leg 15 is extended, and keeps the drill bit completely covered when closed.

[0033] The working principle and usage process of this utility model: When the device is carried, multiple shielding petals 8 evenly surround and completely cover the drilling auger blade 3 to prevent the sharp drill bit from being exposed and scratching the user. At this time, the support leg 15 retracts into the opening 18 inside the shielding petal 8. The overall structure of the device is compact. When it is needed for use, the user rotates the screw sleeve 14 to press it down along the thread of the column 1, forcing the bottom wheel 11 to move downward. The wheel 11 drives the extension rod 12 and push rod 13 connected to it to move down synchronously. The push rod 13 slides inside the sleeve plate 10, pushing the sleeve plate 10 to rotate around the shaft 6. Since the shaft 6 is fixedly connected to the sleeve plate 10, the shaft 6 rotates accordingly, driving the swing rods 7 on both sides to swing outward. The movement of the swing rods 7 causes all the shielding petals 8 to unfold outward synchronously, fully exposing the drilling auger blade 3, ready for sampling. When the shaft 6 rotates, the gear 16 on its surface meshes with the toothed plate 17 on the outside of the support leg 15, driving the support leg 15 to slide outward along the opening 18 of the shielding petal 8, extending to the perimeter of the drilling auger blade 3. After the support leg 15 touches the ground, it forms a stable support to prevent the device from tilting during sampling. When the support leg 15 is fully in contact with the ground, the user rotates the wheel 4, driving the sleeve 2 and the drilling auger blade 3 to drill downward into the soil. At the same time, the support 5 at the top of the column 1 maintains axial stability. After sampling is completed, the wheel 4 is rotated in the opposite direction to extract the sample.

[0034] In summary, this soil and water sample collection device, by setting multiple shielding petals 8 to completely cover the drilling auger blade 3, avoids scratching the user when carrying it. When the shielding petals 8 are closed, they wrap around the drill bit, reducing the size of the device and making it easy to carry. At the same time, the opening and closing structure 9 enables synchronous control of multiple shielding petals 8, eliminating the need for manual adjustment one by one.
