Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of soil sampling, and particularly relates to a portable soil cutting ring sampling handle device. BACKGROUND

[0002] Soil is an indispensable part of the ecological system. In order to evaluate the soil resources in some areas, government departments and scientific researchers use soil cutting rings and matching handles to take soil, and then detect the sampled soil. However, the specifications of the cutting rings gradually expand with the development of scientific research. Nowadays, there are more and more types and specifications of soil cutting rings for different soils and different purposes (including 50.46*50mm, 70*52mm, 40*39.9mm, 61.8*20mm, 79.8*20mm, 61.8*40mm and 100*63.7mm). When used, each cutting ring of different specifications needs to be matched with a handle of the same specification to complete the correct soil taking. Therefore, in order to meet different needs, multiple handles and cutting rings need to be carried during soil taking, which is very troublesome. Based on this, the inventor develops a cutting ring sampling handle which can adapt to cutting rings of different specifications, meets the concept of multiple uses of one handle, and improves the work efficiency and portability of the staff.

Two rotating shafts 7 are rotatably connected in the cavity 5, the two rotating shafts 7 are coaxially arranged, and the two rotating shafts 7 are respectively located on the left and right sides of the rotating shaft 3. The end of the rotating shaft 7 close to each other is coaxially fixed with a driving gear 8, and the driving gear 8 is engaged with the end face gear 6.

[0034] The outer end of the two rotating shafts 7 away from each other is wrapped with a driving roller 9, the outer periphery of the driving roller 9 is provided with threads, and the threads on the two driving rollers 9 are in the same direction. The driving roller 9 is provided with a moving block 10, and the inside of the moving block 10 is provided with an internal thread, so that the moving block 10 is threadedly connected with the driving roller 9.

[0035] The bottom of the main body 1 is provided with a strip-shaped through hole 11 below the two moving blocks 10, and the bottom of the moving block 10 is fixed with a clamping block 12 penetrating through the through hole 11. The two moving blocks 10 are transversely and slidably connected in the cavity 5, and the ends away from each other of the two moving blocks 10 are fixed with a sand blocking piece 13. The bottom of the sand blocking piece 13 is attached to the bottom of the cavity 5.

[0036] The clamping block 12 is L-shaped, and the left clamping block 12 is taken as an example for illustration. Figure 2 As shown in the figure, the right end of the transverse part of the clamping block 12 is provided with a transverse sliding groove 14, and the sliding groove 14 is transversely and slidably connected with a sliding block 15, and the sliding block 15 is wrapped with a sealing ring. Two communication grooves 16 are arranged in the transverse part of the clamping block 12, and the left ends of the two communication grooves 16 are communicated with the left end of the sliding groove 14, and the right ends of the communication grooves 16 are communicated with the outside.

[0037] The communication grooves 16 are transversely and slidably connected with a driving block 17, and the driving block 17 is also wrapped with a sealing ring. The communication grooves 16 and the sliding groove 14 are injected with a communication liquid between the sliding block 15 and the driving block 17, and the communication liquid in this embodiment is oil. The right end face of the sliding block 15 is fixed with a push rod 18, the right end of the push rod 18 is fixed with a flexible block 20, the right end face of the driving block 17 is fixed with a driving rod 19, and the two driving rods 19 are respectively fixed with the two ends of the flexible block 20.

[0038] The left end face of the sliding block 15 and the left end of the sliding groove 14 are welded with a spring, and the spring in this embodiment is selected as a compression spring, and the specific model is selected according to the actual demand. A plurality of strip-shaped grooves 21 are arranged on the right end face of the flexible block 20.

[0039] The specific implementation process is as follows:

[0040] The ring cutter is placed below the main body 1, the operator holds the shell 2 and the holding block 4 with both hands, and rotates the holding block 4, so that the holding block 4 drives the rotating shaft 3 to rotate, thus realizing the rotation of the face gear 6, driving the two rotating rotating shafts through the driving of the driving gear 8, and then realizing the relative movement of the moving block 10 through the cooperation of the threads on the driving roller 9 and the threads on the moving block 10.

[0041] When the moving block 10 moves relatively, the ring cutter will be gradually clamped, so as to realize the fixation of the ring cutter. And in the process of fixing the ring cutter, the flexible block 20 is first attached to the outer wall of the ring cutter, and then gradually extrudes the sliding block 15 to slide into the sliding groove 14, so as to drive the driving block 17 to slide outward through the communication liquid, extrude the two ends of the flexible block 20, so that the flexible block 20 is wrapped outside the ring cutter, and the clamping and fixing effect of the ring cutter is improved.

[0042] Furthermore, during the entire process, when the moving block 10 slides, it will cause the sand-blocking plate 13 to slide, sealing the through hole 11, preventing mud and sand from entering the cavity 5, and reducing the impact on the use of the handle device.

[0043] Example 2:

[0044] The only difference between Example 2 and Example 1 is that, Figure 3 As shown, in this embodiment, the bottom of the main body 1 is provided with a plurality of suction cups 22, and the top of the suction cups 22 is provided with a connecting hole 11; the number of suction cups 22 is set according to actual needs. The main body 1 is provided with a flow channel 23 communicating with the connecting hole 11, and the main body 1 is also provided with a flow channel 24 communicating with the top of the flow channel 23.

[0045] An impeller 25 is installed inside the flow channel 24, and a drive shaft 26 is coaxially mounted on the impeller 25. The rotation of the impeller 25 generates airflow, which discharges the gas in the flow channel 23 through the flow channel 24. The bottom of the rotating shaft 3 is provided with a vertical sliding hole, and the drive shaft 26 is vertically slidably connected in the sliding hole. Therefore, the rotating shaft 3 will drive the drive shaft 26 to rotate synchronously.

[0046] The bottom of the main body 1 is also provided with a slide 27, which is connected to the flow channel 24. A sealing strip 28 is slidably connected inside the slide 27. The sealing strip 28 is provided with a guide port 29 that is connected to the flow channel 24. A spring is provided between the right end of the sealing strip 28 and the right end of the slide 27. The left end of the sealing strip 28 extends into the through hole 11.

[0047] When the ring cutter is fixed, the top of the ring cutter abuts against the bottom of the main body 1, squeezing the suction cup 22. Simultaneously, the rotation of the rotating shaft 3 drives the drive shaft 26 to rotate synchronously, thereby rotating the impeller 25. The rotation of the impeller 25 drives gas flow, expelling the gas from the flow channel 23, allowing the suction cup 22 to firmly hold the top of the ring cutter. During the gradual clamping of the ring cutter, the clamping block 12 squeezes the sealing strip 28, causing the sealing strip 28 to slide within the slide rail 27, thus misaligning the guide port 29 with the flow channel 24, sealing the flow channel 24, and thereby the suction cup 22 firmly and securely holds the ring cutter.

[0048] When the ring cutter is finished and needs to be removed, the drive shaft 3 rotates in the opposite direction, and the moving block 10 moves in the opposite direction. The force squeezing the sealing strip 28 disappears, and the sealing strip 28 resets under the action of the spring. Therefore, the guide port 29 is connected to the flow channel 24, which can guide the external gas into the flow channel 23 and then into the suction cup 22, so that the suction cup 22 can release the ring cutter and make it easy to remove the ring cutter.
