Description

Technical Field

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

[0002] Soil is a vital basic resource for agricultural production, ecological environment, and engineering construction. Its quality is directly related to food security, ecological balance, and engineering stability. Therefore, soil testing has important application value in agriculture, environmental science, geological exploration, and other fields. Soil sampling, as the first step in soil testing, directly affects the reliability of subsequent test results in terms of its efficiency and accuracy.

[0003] Traditional soil sampling methods mainly rely on manual operation, using soil drills or sampling tubes for sampling. Although these methods have played an important role in past practices, with the continuous improvement of testing requirements, the limitations of traditional methods have gradually become apparent. For example, manual operation is labor-intensive, has low sampling efficiency, is easily contaminated, and is difficult to adapt to complex soil conditions, which seriously restricts the efficiency and accuracy of soil testing. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a soil testing sampling device, comprising a cart, wherein the cart is equipped with a support frame, a fixing hook, a side plate and two sets of guide wheels;

[0005] A sleeve plate slides on the column of the support frame. A bottom block is fixed to the bottom of the sleeve plate. A connecting cylinder is installed at the bottom of the bottom block. A sampling cylinder is locked to the inside of the connecting cylinder by bolts. A tensioning component that drives the sleeve plate to rise and fall is installed on the side plate.

[0006] The tensioning assembly includes an upper wheel fixed to the sleeve plate, and a take-up wheel and support frame fixed to the side plate. A rotating rod fixed to the take-up wheel is rotatably connected to the support frame. A drive end for driving the rotating rod to rotate is also installed on the side plate. The rope on the take-up wheel passes around two sets of guide wheels and the upper wheel in sequence and is fixed with a fixing hook.

[0007] Furthermore, the driving end includes a hollow motor, the driving end of which is fixed with a rotating shaft, a driving gear is fixed to the outside of the rotating shaft, and a transmission gear that meshes with the driving gear is fixed to the outside of the rotating rod.

[0008] Furthermore, the bottom of the support frame is torsionally hinged with a hinge block, and a bearing cylinder is hinged to the inner side of the hinge block. The rotating shaft is fixed to the inner rotating end of the bearing cylinder. The rotating end of the hollow motor is provided with a keyway, and a key block located in the keyway is fixed to the outer side of the rotating shaft.

[0009] Furthermore, the top of the support frame is fixed with an upper plate, which has a through hole. The bottom of the upper plate is hinged to a lever plate located in the through hole, and the bottom end of the lever plate is in contact with one side of the drive gear.

[0010] Furthermore, the mounting block and the bottom block are provided with multiple insertion holes at their bottoms, and through holes communicating with the insertion holes are provided on both sides. A hole block adapted to the insertion hole is fixed on the top of the mounting block, and the connecting cylinder is installed at the bottom of the mounting block.

[0011] Furthermore, the protruding end of the sampling tube is fitted with multiple rubber rings.

[0012] Furthermore, anti-collision blocks are fitted onto the outer side of the column of the support frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The soil testing sampling device first moves the trolley to the designated location. Then, the drive end of the tensioning assembly operates. With the cooperation of the fixed hook and guide wheel, the upper wheel tightens and extends, thereby driving the sleeve plate to rise. Under the counterweight of the bottom block, the sleeve plate falls naturally. Under the impact, the sampling cylinder is inserted into the soil, and the soil is compacted in the cylinder to complete the sampling. Therefore, it can reduce the amount of manual labor and improve durability and efficiency. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 This embodiment of a soil testing sampling device includes a cart 1. The cart 1 has an open platform, and a support frame 15 is fixed on the platform. A sleeve plate 16 is slidably connected between two columns of the support frame 15. An upper wheel 41 is installed on the top of the sleeve plate 16, and a base block 17 is fixed at the bottom. A connecting cylinder 19 is installed at the bottom of the base block 17 by screws. A sampling cylinder 20 is fixed at the bottom of the connecting cylinder 19 by locking. A side plate 101 is fixed on the front of the cart 1 chassis. A take-up wheel 4 is installed on the side plate 101, and a drive end for driving the take-up wheel 4 to rotate is installed. A fixing hook 2 is hinged to the top of the cart 1 frame, and guide wheels 3 are installed on both the top and the front. The top guide wheel 3 is hinged. A rope is on the take-up wheel 4. The rope extends upward in sequence, passes around the two guide wheels 3 and the upper wheel 41, and is then fixed to the fixing hook 2.

[0022] In the above structure, by moving the trolley to a suitable position, the drive end rotates the take-up reel. Guided by the guide wheel, the rope is wound up. Simultaneously, with the cooperation of the fixed hook and the upper wheel, the rope lifts the upper wheel, raising the sleeve plate until it reaches the top. After the drive end stops, the sleeve plate falls freely under the guidance of the support frame with the counterweight of the base plate. At the same time, the downward-pressing take-up reel follows to unwind. The bottom block can pass through the opening, so it can fall freely, allowing the sampling tube to be inserted into the soil. The soil is compacted in the sampling tube. The drive end then rotates the take-up reel to wind up the line, raising the sleeve plate to a certain height. This allows the sampling tube to be separated from the connecting tube to complete the collection. When it is necessary to collect again elsewhere, a new sampling tube can be installed, waiting for the next operation to complete the collection again. Therefore, it can reduce the amount of manual labor and improve the persistence and efficiency of sampling.

[0023] Among them, the support frame 15 has anti-collision blocks 151 fitted on the column, which can effectively prevent the frame plate from being damaged by collision with the frame vehicle, and also reduce noise pollution.

[0024] like Figure 2 and 3The drive end includes a support frame 10 fixed on the side plate 101. The inner side of the support frame 10 is rotatably connected to a rotating rod 5 fixed to the take-up wheel 4, and a hinge block 13 is torsionally hinged to it. The inner side of the hinge block 13 is hinged to a bearing cylinder 12. The other end of the rotating rod 5 is fixed to a transmission gear 6. A hollow motor 7 is also installed on the side plate 101. The hollow motor 7 has a rotating shaft 8 fixed to the inner side of the bearing cylinder 12. The inner rotating end of the hollow motor 7 has a keyway. The outer side of the rotating shaft 8 is fixed to a key block 9 that matches the keyway. The outer side of the rotating shaft 8 is fixed to a drive gear 11 that meshes with the transmission gear 6. The top of the support frame 10 is fixed to an upper plate. The upper plate has a rectangular hole. The bottom of the upper plate is hinged to a lever plate 14 that passes through the rectangular hole. One end of the lever plate 14 is arc-shaped and is attached to one side of the drive gear 11.

[0025] Driven by a hollow motor, the rotating shaft rotates in conjunction with the detection and key block. This rotation is then driven by the drive gear, which in turn drives the transmission gear. Simultaneously, the rotating rod and transmission gear move, causing the take-up wheel to wind up the rope, thus raising and lowering the sleeve plate. When the sleeve plate needs to fall freely, the lever is activated, pushing the drive gear to move the rotating shaft. The key block can move axially in the keyway, allowing the rotating shaft to push the hinge block through the bearing sleeve. This separates the drive gear and transmission gear, removing the limit switch on the take-up wheel. Under the weight of the sleeve plate and the base block, the sleeve plate falls freely, completing its lowering. After lowering, the lever resets, and the hinge block, which is torsionally connected, is driven back to its original position by the torsion spring, simultaneously pushing the rotating shaft until the two gears mesh again.

[0026] like Figure 4 The system includes a mounting block 18, with four insertion holes 182 on the bottom of both the mounting block 18 and the base block 17, and two side holes on each of the left and right sides. The side holes communicate with the corresponding insertion holes 182. Four hole blocks 181 are fixed to the top of the mounting block 18, each hole block 181 fitting the insertion holes 182, and the holes may align with the corresponding side holes. Bolts threaded into the side holes and passing through the hole blocks 181 are threaded into them. The connecting cylinder 19 is fixed to the mounting block 18 by screws. Therefore, by adding an appropriate number of mounting blocks, the counterweight can be increased. When soil samples of different elevations need to be taken from the same location, the sampling depth of the sampling cylinder at the same opening can be adjusted by adding mounting blocks, thus enabling stratified sampling.

[0027] The sampling cylinder 20 has multiple rubber rings 21 fitted onto its protruding end. These rubber rings act as a buffer between the sampling cylinder and the connecting cylinder, preventing damage from impact.

[0028] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
