Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a ring cutter quick-removing device. Background Art

[0002] In the construction of water conservancy projects, accurate determination of the physical properties of soil is crucial to the quality and safety of the project. Ring knife sampling is a key method for obtaining undisturbed soil samples. After the soil samples are delivered to the laboratory in a timely manner, their dry density, moisture content and other key parameters are accurately determined with the help of equipment such as balances and ovens. Through these data, we can intuitively understand the compaction quality of the soil and judge whether it meets the compaction standards required by the engineering design. This will lay a solid foundation for the quality of basic construction, ensure the stability of engineering structures such as buildings, roads, and water conservancy facilities, and effectively avoid settlement and collapse risks caused by soil problems. It is widely used in various stages of water conservancy engineering survey, design, construction and monitoring. With the rapid development of my country's water conservancy industry, the number of large-scale water conservancy projects has increased sharply, and the demand for ring knife sampling has exploded.

[0003] The traditional sampling process is mostly done by digging with a shovel, which is time-consuming and labor-intensive. Especially under complex geological conditions, the sampling time of a single ring cutter may be as long as tens of minutes. The success rate of manual sampling is greatly affected by the skills and experience of the operator, which can easily cause sample disturbance or damage, affecting the accuracy of subsequent test results, thereby reducing work efficiency.

[0031] Specifically, the handle bar 3 can drive the connection plate 7 to rotate. The handle bar 3 is made of stainless steel. The length of the handle bar 3 is greater than 1 meter, which makes it easy to apply pressure to the connection plate 7. The handle bar 3 can be rotated inside the hand-held tube 2 through the hand-held tube 2, so that manual rotation is not required, which makes it more convenient to apply torque to the handle bar 3. The verticality of the entire device can be intuitively seen through the level 1, which makes the device run more accurately. The friction with the hand can be increased through the vertical groove, which makes it easier to apply force. The rotating handle 4 can be fixed to the outer wall of the handle bar 3 through the sliding tube 5, and the rotating handle 4 can move up and down more smoothly. The rotating handle 4 can apply torque to the handle bar 3. The anti-slip sleeve 12 can increase the friction when operating the rotating handle 4, and the connecting disk 7 can connect the cone 10. The connecting disk 7 is made of stainless steel and the upper surface is covered with a rubber layer to achieve a shock-absorbing effect. The ring knife 21 can cut the soil. The diameter of the connecting disk 7 is 1.5 times the diameter of the ring knife 21, so the force transmitted through the connecting disk 7 can be efficiently transmitted to the ring knife 21. The cone 10 can be inserted into the soil. The bottom of the cone 10 is in the shape of a spike, which makes it easier to insert the cone 10 into the soil.

[0033] Specifically, the rotating handle 4 can be inserted through the adjustment hole 6. Five adjustment holes 6 are evenly arranged on the outer wall of the handle rod 3 so that the rotating handle 4 can be inserted into different adjustment holes 6, thereby changing the height of the rotating handle 4, which makes it easier to apply force.

[0034] Please see attached Figure 6 A mounting groove 16 is formed on the side wall of the cone 10 , and the end of the blade 11 fits into the mounting groove 16 .

[0035] Specifically, the root of the blade 11 can be fitted and fixed through the mounting groove 16, and a new blade 11 can be easily replaced after the blade 11 is aged, or a blade 11 with higher hardness can be replaced when encountering hard soil, so that the soil can be cut more easily.

[0036] Please see attached Figure 3 -Attached Figure 8An inner cavity 17 is opened in the middle of the cone 10, a pull rod 9 is fixedly provided on the connecting disk 7, a thread is opened on the top of the pull rod 9, a fixed support block 24 is fixedly connected to the top of the connecting disk 7, a rotating shaft 23 is fixedly connected to the upper part of the fixed support block 24, a gear 8 is rotatably provided on the outer wall of the rotating shaft 23, a handle 22 is fixedly connected to the outer wall of the gear 8, the outer wall of the gear 8 is meshed with the top thread of the pull rod 9, the pull rod 9 is located inside the inner cavity 17, the bottom of the pull rod 9 is fixedly connected to the top of the sliding block 14, a first fixed rod 13 is provided in the middle of the sliding block 14, and a cross-cutting rod 15 is rotatably provided on the outer wall of the first fixed rod 13.

[0037] Specifically, the inner cavity 17 can make the internal structure movable, the pull rod 9 can drive the sliding block 14 to move up and down, a thread is provided on the top of the pull rod 9, and the outer wall of the gear 8 is meshed with the top thread of the pull rod 9, so that the position of the pull rod 9 can be changed when the gear 8 is rotated, making it easier to manually change the height of the pull rod 9, and the rotating shaft 23 can be supported by the fixed support block 24, and the rotating shaft 23 can play the role of fixing the gear 8, so that the gear 8 can only rotate around the rotating shaft 23, and the gear 8 can be simply and directly rotated by the handle 22, and the transverse rod 15 can be fixed to the outer wall of the first fixed rod 13 through the sliding block 14, thereby driving the tail of the transverse rod 15 to move up and down, and then the tail of the transverse rod 15 rotates around the center point of the first fixed rod 13.

[0038] Please see attached Figure 7 -Attached Figure 8 A slide groove 19 is provided on the outer wall of the cross-cutting rod 15, the sliding block 14 fits inside the inner cavity 17, a through hole 18 is provided on the side of the cone 10 close to the cross-cutting rod 15, and second fixing rods 20 are provided on both sides of the cross-cutting rod 15, one end of the second fixing rod 20 is fixedly connected to the side wall of the through hole 18, and the other end of the second fixing rod 20 is located inside the slide groove 19.

The through hole 18 can make it easy for the cross-cutting rod 15 to be retracted into the cone 10, thereby reducing the resistance when the cone 10 is inserted into the soil. The second fixed rod 20 can cooperate with the slide groove 19 to allow the cross-cutting rod 15 to slide and rotate at the same time.

[0040] Please see attached Figure 1 -Attached Figure 5 The cones 10 are arranged in a circular array with the connecting disk 7 as the center, and there are 4 of them in total.

[0041] Specifically, the cone 10 can be more firmly inserted into the soil.

[0042] Please see attached Figure 1 , the length of the rotating handle 4 is greater than 0.5 meter.
