Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a mobile forestry soil sampler. Background Technology

[0002] Soil sampling is a fundamental task in forestry resource management, ecological environment monitoring, and forestry scientific research. Analysis of soil samples reveals information about soil physicochemical properties (such as organic matter content, pH value, and nutrient status), heavy metal content, and microbial community structure. This data is crucial for assessing forest productivity, developing forest cultivation programs, monitoring the health of forest ecosystems, and addressing climate change.

[0003] Traditional sampling tools often have an integrated or difficult-to-disassemble sleeve and body. After sampling, the soil remaining inside the sleeve and in the drill bit gaps is difficult to completely remove. This not only increases cleaning time and labor intensity, but also easily leads to residual soil being mixed into the next sample, causing data deviation.

[0004] In response to the technical problem of difficulty in cleaning the soil residue inside traditional samplers, this application proposes a mobile forestry soil sampler. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of traditional samplers, which leave residual soil inside. A mobile forestry soil sampler is proposed, allowing the sleeve to be removed from the crossbar for easier cleaning of the soil on the sleeve and drill bit, thus improving cleaning efficiency. Furthermore, the depth of the drill bit into the ground can be determined by the distance the sliding sleeve travels on the outer wall of the sleeve and by the scale lines on the outer wall of the sleeve, ensuring that the sampling depth meets the preset requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile forestry soil sampler, comprising a crossbar, a drill bit rotatably connected to the inner wall of the crossbar, a sleeve provided at the bottom end of the crossbar, a positioning groove provided at the bottom end of the crossbar, the inner wall of the positioning groove fitting the shape of the outer wall of the sleeve, fixing blocks fixedly connected to both sides of the outer wall of the sleeve, a knob provided at the front end of the crossbar, a screw fixedly connected to the rear end of the knob, the outer wall of the screw rotatably connected to the inner wall of the crossbar, the screw connected to the fixing blocks through a fixing component, and a sliding sleeve provided on the outer wall of the sleeve, the sliding sleeve connected to the sleeve through a telescopic component.

[0007] Furthermore, the fixing assembly includes a threaded sleeve threadedly connected to the outer wall of the screw, the outer wall of the threaded sleeve being slidably connected to the inner wall of the crossbar, and support rods being rotatably connected to both sides of the outer wall of the threaded sleeve.

[0008] Furthermore, each of the other ends of the support rod is rotatably connected to a locking block, the outer wall of the locking block is slidably connected to the inner wall of the crossbar, and the inner wall of each fixing block is provided with a locking groove, the shape of the locking block and the locking groove being matched.

[0009] Furthermore, the telescopic assembly includes sliders fixedly connected to both sides of the inner wall of the sleeve, the outer wall of the sliders being slidably connected to the inner wall of the sleeve, and a spring fixedly connected to the top of each slider, the other end of each spring being fixedly connected to the inner wall of the sleeve.

[0010] Furthermore, each slider has a baffle fixedly connected to its top end, and the outer wall of the baffle is slidably connected to the inner wall of the sleeve.

[0011] Furthermore, a motor is fixedly connected to the top of the crossbar, and the top of the drill bit is fixedly connected to the motor drive end.

[0012] Furthermore, a discharge pipe is fixedly connected to the front end of the sleeve, and sliding rods are fixedly connected to both the left and right sides of the discharge pipe.

[0013] Furthermore, a storage box is provided on the outer wall of the discharge pipe, and sliding grooves are provided on both sides of the inner wall at the rear end of the storage box, and the sliding rod is engaged with the sliding grooves.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the screw is rotated by turning the knob, which in turn moves the locking blocks on both sides, so that the locking blocks can remove the restriction on the fixing block, and the sleeve can be removed from the crossbar. This makes it easier to clean the inside of the sleeve and the drill bit, improves the cleaning efficiency, and prevents residual soil from interfering with the next sampling data.

[0016] 2. In this utility model, by fitting the sliding sleeve to the ground, starting the drill bit with the motor, and pressing the crossbar downwards, the drill bit is driven into the ground. The sliding sleeve moves on the outer wall of the sleeve. The depth of the drill bit into the ground can be known by the sliding sleeve on the outer wall of the sleeve and the scale lines on the outer wall of the sleeve, ensuring that the sampling depth meets the preset requirements, improving the representativeness of the sample and the reliability of the experimental data.

[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a mobile forestry soil sampler, comprising a crossbar 1, a drill bit 3 rotatably connected to the inner wall of the crossbar 1, a sleeve 4 at the bottom end of the crossbar 1, a positioning groove 12 at the bottom end of the crossbar 1, the inner wall of the positioning groove 12 fitting the shape of the outer wall of the sleeve 4, fixing blocks 5 fixedly connected to both sides of the outer wall of the sleeve 4, a knob 7 at the front end of the crossbar 1, a screw 8 fixedly connected to the rear end of the knob 7, the outer wall of the screw 8 rotatably connected to the inner wall of the crossbar 1, a threaded sleeve 9 threadedly connected to the outer wall of the screw 8, the outer wall of the threaded sleeve 9 slidably connected to the inner wall of the crossbar 1, support rods 10 rotatably connected to both sides of the outer wall of the threaded sleeve 9, a locking block 11 rotatably connected to the other end of each support rod 10, the outer wall of the locking block 11 slidably connected to the inner wall of the crossbar 1, a locking groove 6 on the inner wall of each fixing block 5, the locking block 11 fitting the shape of the locking groove 6, a motor 2 fixedly connected to the top end of the crossbar 1, and the top end of the drill bit 3 fixedly connected to the drive end of the motor 2.

[0027] Specifically, when installing the sleeve 4, first align the top of the sleeve 4 with the positioning groove 12, then insert the fixing blocks 5 on both sides of the sleeve 4 into the crossbar 1, and at the same time, make the top of the sleeve 4 enter the positioning groove 12. Then, turn the knob 7 to make the screw 8 rotate. The screw 8 will then move the locking blocks 11 on both sides to the sides through the threaded sleeve 9 and the support rod 10, so that the locking blocks 11 enter the locking grooves 6 on the fixing blocks 5, thereby fixing the sleeve 4. The top of the sleeve 4 is open so that the drill bit 3 can be moved out from the top of the sleeve 4.

[0028] Reference Figures 4-6 The outer wall of the sleeve 4 is provided with a sliding sleeve 16. The inner walls of the sliding sleeve 16 are fixedly connected to two sides of the sliding sleeve 16. The outer walls of the sliding sleeve 17 are slidably connected to the inner wall of the sleeve 4. The top of each sliding sleeve 17 is fixedly connected to a spring 18. The other end of each spring 18 is fixedly connected to the inner wall of the sleeve 4. The top of each sliding sleeve 17 is fixedly connected to a baffle 19. The outer walls of the baffle 19 are slidably connected to the inner wall of the sleeve 4. The front end of the sleeve 4 is fixedly connected to a discharge pipe 13. The left and right sides of the discharge pipe 13 are fixedly connected to sliding rods 14. The outer wall of the discharge pipe 13 is provided with a storage box 15. The inner walls of the rear end of the storage box 15 are provided with sliding grooves on both sides. The sliding rods 14 are fitted into the sliding grooves.

[0029] Specifically, the outer wall of the sleeve 4 is engraved with scale lines to observe the distance the sliding sleeve 16 moves. When the slider 17 moves up to compress the spring 18, the slider 17 will simultaneously drive the baffle 19 to move upward. The spring 18 is located inside the baffle 19, so that the baffle 19 protects the spring 18. An elastic protrusion is fixed on the sliding rod 14. When the sliding rod 14 is inserted into the groove on the storage box 15, the elastic protrusion can be stuck in the groove.

[0030] Working Principle: This device is compact and lightweight, making it easy for users to handle and move. When installing the storage box 15 onto the discharge pipe 13, first align the sliding groove on the storage box 15 with the sliding rod 14 on the discharge pipe 13 and insert it so that the sliding groove is locked onto the outer wall of the sliding rod 14, thereby fixing the storage box 15 onto the discharge pipe 13. Then, start the motor 2, which drives the drill bit 3 to rotate. Next, hold the crossbar 1, press the sliding sleeve 16 against the ground, and press it down so that the sliding sleeve 16 slides on the outer wall of the sleeve 4, while the drill bit 3 drills into the ground. During the rotation of the drill bit 3, soil is transported into the sliding sleeve 16 and the inside of the sleeve 4. The soil in the sleeve 4 will enter the storage box 15 for collection through the discharge pipe 13. As the drill bit 3 continues to move into the ground, the sliding sleeve 16 will continuously move upwards on the outer wall of the sleeve 4. When the sleeve 4 moves, it moves upward via slider 17 and compresses spring 18. When the sliding sleeve 16 moves on the outer wall of the sleeve 4, it can be compared with the scale line on the outer wall of the sleeve 4. The distance that the sliding sleeve 16 moves upward is the distance that the drill bit 3 drills into the ground. When the drill bit 3 is moved out of the ground via the crossbar 1, spring 18 will rebound slider 17 downward, causing slider 17 to drive sliding sleeve 16 to return to its original position. When cleaning the sleeve 4 and the drill bit 3, the knob 7 can be turned to drive screw 8 to rotate. Screw 8 will drive threaded sleeve 9 to move. Threaded sleeve 9 will drive the locking block 11 to move towards the middle of the crossbar 1 via the support rods 10 on both sides, so that the locking block 11 disengages from the locking groove 6 on the fixing block 5, so that the sleeve 4 can be removed from the crossbar 1 for easy cleaning, so that no soil residue will remain during the next collection.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
