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.
[0028] like Figure 1-4 As shown:
[0029] A soil sampling device for geological exploration includes a fixing cap 105 and a sampling cylinder 103 fixed on the fixing cap 105. The top of the fixing cap 105 is rotatably connected to a screw 106 via a bearing. The device also includes a storage box 101. A limiting ring 102 for inserting the sampling cylinder 103 is provided inside the storage box 101. A symmetrically arranged connecting pin is fixed on the surface of the limiting ring 102. The connecting pin is rotatably connected to the storage box 101 via a bearing.
[0030] The storage box 101 has a sampling hole 104 that is compatible with the sampling tube 103;
[0031] The screw 106 is threadedly connected to a U-shaped frame 107. The two ends of the U-shaped frame 107 are fixed to two sets of connecting pins. A limit block is fixed to the surface of the fixing cap 105, and a limit groove adapted to the limit block is opened on the inner side wall of the U-shaped frame 107. The limit block can slide in the limit groove opened in the U-shaped frame 107.
[0032] The storage box 101 has a cover plate 109 at its opening. One side of the storage box 101 is fixed with symmetrically arranged hinge seats. One side of the cover plate 109 is located between the two sets of hinge seats and is hinged to each other by a hinge shaft.
[0033] A locking mechanism 2 for locking the position of the U-shaped frame 107 is installed on the cover plate 109;
[0034] The locking mechanism 2 includes a rectangular groove on the cover plate 109 and a lead screw 202 disposed in the rectangular groove. The two ends of the lead screw 202 are rotatably connected to the cover plate 109 through bearings. The two sides of the U-shaped frame 107 are provided with L-shaped limiting clamping plates 201. The two ends of the lead screw 202 are provided with opposite threads. The two sets of limiting clamping plates 201 are threadedly connected to the opposite threads of the lead screw 202 through threaded holes. The two sides of the U-shaped frame 107 are provided with slots 203 that are adapted to the limiting clamping plates 201. One end of the limiting clamping plate 201 can be inserted into the slot 203 of the U-shaped frame 107. The limiting clamping plate 201 slides in cooperation with the rectangular groove of the cover plate 109.
[0035] A threaded pin 111 is provided on one side of the storage box 101 to lock the cover plate 109 at a 90° position. A fixing plate 110 is fixed on one side of the storage box 101. The fixing plate 110 is threadedly connected to the threaded pin 111 through a threaded hole. A locking groove adapted to the threaded pin 111 is provided on one side of the cover plate 109. The threaded pin 111 is inserted into the locking groove of the cover plate 109 to lock the cover plate 109 at a 90° position.
[0036] A set of four casters 112 are fixedly installed at one end of the storage box 101 at its four corners;
[0037] An elastic buckle 115 is installed at one end between the storage box 101 and the cover plate 109. The elastic buckle 115 is used to connect and lock the folded cover plate 109 and the storage box 101. The elastic buckle 115 includes an elastic female buckle and a male buckle. The male buckle is fixed on one side of the cover plate 109, and the elastic female buckle is fixed on the storage box 101.
[0038] The other two sides of the storage box 101 are fixedly mounted with side seats 114, and a pull rod 113 is installed between the two sets of side seats 114.
[0039] In this implementation plan: When the geological exploration soil sampling device is in use, the screw 106 is rotated and threadedly connected to the U-shaped frame 107, thereby driving the fixing cap 105 to move downward. During the process of the fixing cap 105 driving the sampling cylinder 103 to move downward synchronously, the limiting block slides in the limiting groove opened in the U-shaped frame 107 to realize the synchronous limiting of the fixing cap 105 and the sampling cylinder 103, thus ensuring the stability of the downward movement of the sampling cylinder 103;
[0040] As the sampling tube 103 moves down, it passes through the sampling hole 104 opened in the storage box 101 and is inserted into the soil to take soil samples. The sampling hole 104 is adapted to the outer surface diameter of the sampling tube 103. When the sampling tube 103 is lifted, the soil carried on the sampling tube 103 can be effectively scraped off.
[0041] The sampling cylinder 103 and soil are taken out together by rotating the screw 106. After sampling, the locking mechanism 2 releases the lock on the U-shaped frame 107. During this process, the screw 202 is turned and the two sets of limiting clamping plates 201 are screwed to the screw 202. When the screw 202 rotates, it can drive the two sets of limiting clamping plates 201 to move away from each other, thereby disengaging the limiting clamping plates 201 from the slots 203 of the U-shaped frame 107, releasing the lock on the U-shaped frame 107, and causing the U-shaped frame 107 to fold to 90°. The sampling cylinder 103 and the screw 106 then fold into the storage box 101.
[0042] At the same time, by screwing the threaded pin 111 on the fixing plate 110, the threaded pin 111 can be disengaged from the locking groove opened in the cover plate 109, releasing the lock on the cover plate 109. Then the cover plate 109 is flipped to 90° to seal the opening of the storage box 101.
[0043] The elastic buckle 115 includes an elastic female buckle and a male buckle. The male buckle is fixed on one side of the cover plate 109, and the elastic female buckle is fixed on the storage box 101. When the cover plate 109 is flipped to 90° to block the opening of the storage box 101, the elastic female buckle can be locked onto the male buckle on the cover plate 109, thereby achieving the connection and locking between the cover plate 109 and the storage box 101.
[0044] This solution can compactly fold and store components such as the sampling cylinder 103 and screw 106 into the storage box 101. Its small size greatly reduces the carrying burden of field workers and improves the flexibility of field operations. At the same time, a moving wheel 112 is provided on one side of the storage box 101. The design of the moving wheel 112 allows the limiting ring 102 to move easily on the plane, which is convenient for frequent handling of tools or items, reduces labor intensity, and saves more effort.
[0045] It should be noted that the hand-held lever 113 can be pulled flexibly, so that one end of the lever 113 is at the most suitable height for the person holding it, which makes it easier to push the storage box 101. The specific connection structure between the lever 113 and the side seat 114 can refer to the design of the suitcase lever, which can be used as an existing technical reference, so it will not be described in detail.
[0046] It should be noted that the sampling cylinder 103 can be designed to be divided into two parts and fixed to the fixing cap 105 with bolts, which makes it convenient to disassemble and assemble the sampling cylinder 103.
[0047] Furthermore;
[0048] In an optional embodiment, the inner wall of the storage box 101 is fixed with two sets of baffles 108 for positioning and blocking the U-shaped frame 107.
[0049] In this embodiment: when the U-shaped frame 107 is flipped, when one side of the U-shaped frame 107 is in contact with the surface of the stop bar 108, the U-shaped frame 107 can be flipped and positioned at a 90° angle.
[0050] The working principle and usage process of this utility model are as follows: In use, this geological exploration soil sampling device rotates the screw 106, which is threadedly connected to the U-shaped frame 107. This drives the fixing cap 105 to move downwards. As the fixing cap 105 moves the sampling cylinder 103 downwards, it passes through the sampling hole 104 in the storage box 101 and inserts into the soil for sampling. The sampling hole 104 is adapted to the outer diameter of the sampling cylinder 103. When the sampling cylinder 103 is lifted, it can effectively scrape off the soil samples carried on it. Soil is extracted by rotating the screw 106, which together removes the sampling cylinder 103 and the soil. After sampling, the locking mechanism 2 releases the lock on the U-shaped frame 107. During this process, the screw 202 is turned, and the two sets of limiting clamping plates 201 are screwed to the screw 202. When the screw 202 rotates, it can drive the two sets of limiting clamping plates 201 to move away from each other, thereby disengaging the limiting clamping plates 201 from the slots 203 of the U-shaped frame 107, releasing the lock on the U-shaped frame 107, and causing the U-shaped frame 107 to fold to 90°. The sampling cylinder 103 and the screw 106 then fold into the storage box 101.
[0051] Simultaneously, by screwing the threaded pin 111 on the fixing plate 110, the threaded pin 111 can be disengaged from the locking groove of the cover plate 109, releasing the lock on the cover plate 109. Then, the cover plate 109 is flipped to 90° to seal the opening of the storage box 101. The connection and locking between the cover plate 109 and the storage box 101 are achieved by the elastic buckle 115. This solution can compactly fold and store components such as the sampling cylinder 103 and the screw 106 into the storage box 101. The compact size greatly reduces the carrying burden of field workers and improves the flexibility of field operations. At the same time, a moving wheel 112 is provided on one side of the storage box 101. The design of the moving wheel 112 allows the limiting ring 102 to move easily on the plane, which is convenient for frequent handling of tools or items, reducing labor intensity and saving effort.
[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
