Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil sampling instruments, in particular to an improved device for a soil sampling handle of a cutting ring. Background Art
[0002] In the fields of engineering geology, soil science, etc., the cutting ring method is the most efficient and convenient method for measuring the physical properties of soil currently used, and is also the most widely used method. The tools for soil sampling mainly include a cutting ring, a handle, a rubber hammer, etc. The cutting ring is a special cylindrical metal container with openings at both the upper and lower ends. When taking soil with a cutting ring, first level the surface of the selected sampling site, and then press the cutting ring vertically into the soil until the cutting ring is completely embedded in the soil.
[0003] However, the current handle, as a fixed and force-conducting tool connecting the cutting ring and the rubber hammer, is mostly made of solid cast iron or other metals poured. During the soil sampling process, the embedding depth of the cutting ring cannot be seen. Therefore, in order to avoid the soil in the cutting ring being extruded by external forces due to the cutting ring being embedded too deep, resulting in the physical properties such as soil bulk density not conforming to the actual situation, it is necessary to frequently remove the handle during the soil sampling process to observe the embedding situation of the cutting ring. Especially when the soil in the cutting ring is close to the top of the cutting ring, the sampler needs to be more careful, which seriously affects the soil sampling efficiency; in addition, in relatively loose soil, when the rubber hammer is used normally, the cutting ring will quickly be completely embedded in the soil, and the sampler often causes the cutting ring to be embedded too deep when not paying attention, and the soil in the cutting ring is extruded by a strong external force, and the physical properties change, affecting the test results. Content of the Utility Model
[0004] The purpose of the utility model is to provide an improved device for a soil sampling handle of a cutting ring to solve the above deficiencies in the prior art.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] An improved device for a soil sampling handle of a cutting ring includes a handle portion. One end of the handle portion is fixedly connected with a connecting plate. The connecting plate is provided with a first slot and a second slot that are communicated with each other. The first slot is adapted to the outer wall of the cutting ring, and the second slot is adapted to the inner wall of the cutting ring; a plurality of cylindrical pins are slidably connected to the connecting plate, and the ends of the cylindrical pins are fixedly connected to a baffle. The outer wall of the baffle is adapted to the second slot. A bolt is threadedly connected to the upper end of each cylindrical pin, and a reminder band for indicating the depth of the soil in the cutting ring is provided.
[0007] Furthermore, a plurality of sleeves corresponding to the cylindrical pins one by one are provided on the connecting plate. The sleeves are slidably connected with the cylindrical pins, and the head of the screw abuts against the sleeves.
[0008] Further, a plurality of springs corresponding to the cylindrical pins one by one are provided between the connecting plate and the baffle, and the springs are inserted outside the cylindrical pins.
[0009] Further, the indicating band is a color provided on the outer surface of the cylindrical pin.
[0010] Further, it further includes a rotating ring threadedly connected to the connecting plate. A vertical rod and a horizontal rod are respectively slidably connected to the connecting plate. The vertical rod extends into the circumferential inclined groove inside the rotating ring, and the rotating ring rotates to make the horizontal rod abut against the outer wall of the core cutter through the vertical rod.
[0011] Further, first inclined surfaces and second inclined surfaces are respectively provided at both ends of the vertical rod, and the first inclined surfaces are attached to the inclined grooves.
[0012] In the above technical solution, the beneficial effects of an improved device for the core cutter soil sampling handle provided by the present utility model are as follows:
[0013] By providing the cylindrical pin, when using the core cutter method to take soil, a tool such as a hammer is used to hammer the handle part. The handle part drives the core cutter to embed into the soil through the lower end surface of the second slotted opening on the connecting rod. The soil in the core cutter will push the cylindrical pin upward through the baffle. When the sampler observes the indicating band, the soil in the core cutter just reaches the top of the core cutter. The sampler can complete soil sampling without frequently removing the handle, and it will not cause the physical properties to change due to excessive hammering, ensuring the stability of the test results.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0031] Please refer to Figures 1-6 , an improved device for a soil sampling handle of a ring cutter, including a handle 1, wherein an end of the handle 1 is fixedly connected with a connecting plate 11, a first slot 12 and a second slot 13 which are communicated with each other are formed on the connecting plate 11, the first slot 12 is adapted to the outer wall of the ring cutter, and the second slot 13 is adapted to the inner wall of the ring cutter; a plurality of cylindrical pins 2 are slidably connected to the connecting plate 11, ends of the cylindrical pins 2 are fixedly connected to a baffle 21, an outer wall of the baffle 21 is adapted to the second slot 13, bolts 22 are threadedly connected to upper ends of the cylindrical pins 2, and a reminder strip for indicating the depth of soil in the ring cutter is provided.
[0032] Through the provided cylindrical pin 2, when taking soil samples using the ring knife method, a tool such as a hammer is used to strike the handle portion 1. The handle portion 1 drives the ring knife to embed into the soil through the lower end surface of the second slotted opening 13 on the connecting rod. The soil inside the ring knife will push the cylindrical pin 2 upward through the baffle 21. When the sampler observes the indicating strip, the soil in the ring knife reaches exactly the top of the ring knife. The sampler can complete soil sampling without frequently removing the handle, and it will not cause the physical properties to change due to excessive hammering, ensuring the stability of the test results.
[0033] Further, a plurality of sleeves 3 corresponding to the cylindrical pins 2 one by one are provided on the connecting plate 11. The sleeves 3 are slidably connected to the cylindrical pins 2, and the screw head abuts against the sleeves 3. The stability of the sliding of the cylindrical pin 2 is further improved through the sleeves 3, and the screw head abuts against the sleeves 3 to prevent the cylindrical pin 2 from detaching from the connecting plate 11.
[0034] Further, a plurality of springs 4 corresponding to the cylindrical pins 2 one by one are provided between the connecting plate 11 and the baffle 21. The springs 4 are inserted outside the cylindrical pins 2. The springs 4 keep the screw head tightly abutted against the sleeves 3 to buffer the collisions between the baffle 21 and the connecting plate 11 and between the screw head and the sleeves 3.
[0035] Further, the indicating strip is a color provided on the outer surface of the cylindrical pin 2. The color can be a gradient color or a combination of multiple colors. When the soil in the ring knife approaches the top of the ring knife, the sampler can reduce the hammering force through the color change of the ring knife. When the soil pushes up the baffle 21 so that the lower section of the baffle 21 and the lower section of the second slotted opening 13 are on the same plane, it indicates that the soil in the ring knife has reached the same level as the top of the ring knife; the indicating strip can also be a groove, a scale line, etc. that can provide visual differentiation.
[0036] Further, it further includes a rotating ring 5 threadedly connected to the connecting plate 11. A vertical rod 52 and a horizontal rod 53 are respectively slidably connected to the connecting plate 11. The vertical rod 52 extends into the circumferential inclined groove 51 inside the rotating ring 5. When the rotating ring 5 rotates, the horizontal rod 53 abuts against the outer wall of the ring knife through the vertical rod 52. First inclined surfaces 54 and second inclined surfaces 55 are respectively provided at both ends of the vertical rod 52, and the first inclined surface 54 fits with the inclined groove 51. Protrusions for slidably connecting with the connecting rod are respectively provided on the horizontal rod 53 and the vertical rod 52 to prevent the horizontal rod 53 and the vertical rod 52 from sliding out of the connecting plate 11.
[0037] When the rotating ring 5 is rotated, the inclined groove 51 causes the vertical rod 52 to move through the first inclined surface 54, and the vertical rod 52 causes the horizontal rod 53 to move through the second inclined surface 55, so that the horizontal rod 53 abuts tightly against the outer wall of the ring knife, facilitating the sampler to pull out the ring knife through the handle portion 1 without using other tools to dig out the ring knife. Corresponding locking grooves can also be provided on the outer wall of the ring knife to allow the horizontal rod 53 to extend into the locking grooves to further improve the stability of the connection to the ring knife.
[0038] Working principle: When taking soil by the cutting ring method, rotate the rotating ring 5. The chute 51 causes the vertical rod 52 to move through the first inclined surface 54. The movement of the vertical rod 52 causes the cross rod 53 to move through the second inclined surface 55, so that the cross rod 53 abuts against the outer wall of the cutting ring. Hammer the handle 1 with tools such as a hammer. The handle 1 drives the cutting ring to embed into the soil through the lower end surface of the second slot 13 on the connecting rod. The soil in the cutting ring will push the cylindrical pin 2 upward through the baffle 21. When the sampler observes the indicating strip, the soil in the cutting ring just reaches the top of the cutting ring. The sampler can complete soil sampling without frequently removing the handle, and it will not cause the physical properties to change due to excessive hammering, ensuring the stability of the test results.
[0039] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
