Description

Technical Field

[0001] The utility model relates to the field of soil density test sampling tools, in particular to a device for flattening both ends of a ring knife. Background Art

[0002] According to GB / T 50123-2019, during the density test of soil using the knife ring method, the knife ring needs to be inserted into the soil to take a sample. After the knife ring is removed, the inside of the knife ring is filled with soil. The excess soil at both ends of the knife ring is then cut flat to obtain a soil sample that is flush with the inner diameter of the knife ring. The soil density is then calculated. However, during the density test using the knife ring method, the sampler needs to manually and slowly cut the soil sample at both ends of the knife ring. There are no auxiliary precision tools during the cutting process, resulting in an uneven cutting surface that is prone to unevenness errors, which in turn causes errors in the measurement results. This is a disadvantage. Utility Model Content

[0003] In order to solve the problem that in the existing ring knife sampling process, the soil samples at both ends of the ring knife need to be slowly cut manually, resulting in the cut surface not necessarily being flat and prone to uneven errors, the present application provides a device for cutting both ends of the ring knife. When the worker uses the ring knife to take the soil sample, the ring knife with the soil sample can be placed in the positioning part of the base body, and then the cutting knife in the knife holder can be controlled to cut the soil samples at both ends of the ring knife. The excess soil samples at both ends of the ring knife will be cut off flatly, and the required soil samples are obtained. The soil samples at both ends of the ring knife can be directly cut off at one time, so that the cutting surfaces at both ends of the soil sample are flat, which reduces the manual error of the experiment and reduces the experimental error.

[0004] The present invention adopts the following technical scheme: a device for cutting the two ends of a ring knife flat, comprising a base body, a positioning part, and a tool holder, wherein the base body is provided with a positioning part for placing the ring knife, the ring knife can be placed in the positioning part for positioning, rotatable tool holders are provided at both ends of the positioning part, and the tool holder is provided with cutting knives for cutting the two ends of the positioning part, the rotating shaft of the tool holder is connected to the bracket on the base body, and the tool holder can rotate in the axial hole of the bracket with the rotating shaft as the axis, and the rotation of the tool holder can control the two cutting knives to cut the two end faces of the ring knife placed in the positioning part, and rotating the tool holder once can control the cutting knives to cut the soil samples at both ends of the ring knife, so that the cutting surfaces of the two ends of the ring knife soil sample are smooth, thereby reducing the manual error of the test and reducing the test error.

[0005] The tool holder is provided with a movable and adjustable adjustment frame, both ends of the adjustment frame are provided with sliding bones, and the adjustment frame is provided with an adjustable cutting knife, and the movement of the adjustment frame drives the adjustable cutting knife to move.

[0006] The left and right ends of the tool holder are provided with sliding grooves on the inner sides, and sliding bones are provided at both ends of the adjustment frame. The sliding bones can be inserted into the sliding grooves for cooperation. The sliding grooves clamp and support the sliding bones, and the sliding bones can slide and adjust the position in the sliding grooves. When the adjusting frame moves, the sliding bones move in the sliding grooves. Locking screws are provided at both ends of the adjusting frame. When the locking screws are tightened, the adjusting frame can be fixed in the tool holder. When the locking screws are loosened, the adjusting frame can move the adjustment position with the sliding bones as the guide center to perform tool alignment, thereby realizing that the distance between the two cutting knives can be adjusted.

[0007] The cutting area is defined by a fixed cutting blade mounted on the tool holder and an adjustable cutting blade mounted on an adjustment frame. The distance between the fixed and adjustable cutting blades in the tool holder is the length of the ring blade. The distance between the two cutting blades can be adjusted by moving the adjustment frame, accommodating ring blades of varying lengths and sizes. This provides greater flexibility and compatibility with a wide range of ring blade models.

[0008] The positioning portion of the base body is in the shape of an arc-shaped opening, and a stop is provided at the end of the arc-shaped opening. The stop is aligned with the fixed cutting blade provided in the tool holder. When the ring cutter is placed in the positioning portion, any end is moved until it collides with the stop, and the end face is aligned with the fixed cutting blade in the tool holder, completing the tool alignment of the end face. The adjustable cutting blade is then aligned with the other end face of the ring cutter in the positioning portion by moving the adjustment frame. The distance between the fixed cutting blade and the adjustable cutting blade on the adjustment frame is the length of the ring cutter. At this time, when the tool holder rotates clockwise, the fixed cutting blade and the adjustable cutting blade are controlled to rotate clockwise, aligning the two end faces of the ring cutter for cutting, cutting off the excess soil on the two end faces, and obtaining a smooth cutting end face.

[0009] The stop depth of the end of the positioning portion in the seat body is 0.5-1.5MM, which can not only play the role of collision positioning, but also prevent the fixed cutting knife from being unable to completely cut the entire end face during cutting.

[0010] The tool holder is provided with a handle, and the user can grasp the handle and rotate the tool holder with the rotating shaft as the axis, thereby controlling the two cutting knives to rotate and cut or rotate and open.

[0011] The base body is provided with a plurality of slag discharge grooves, and during the cutting process, excess soil at both ends of the ring cutter will fall out of the slag discharge grooves and be discharged, thereby preventing excess soil from accumulating on the upper end surface of the base body.

[0012] The upper end faces of the slide grooves at the left and right ends of the tool holder can be provided with scale values, which mark the distance between the two cutting knives. By moving the adjustment frame to align with the scale values ​​at different positions, the distance between the two cutting knives can be confirmed to be the same as the length of the ring knife, and then the locking screws are tightened to connect the adjustment frame to the tool holder. When cutting, it is only necessary to adjust the distance between the two cutting knives to be the same as the length of the ring knife, place the ring knife filled with soil into the positioning part, and collide with either end with the gear position to complete the tool alignment. Then, rotate the tool holder clockwise to control the two cutting knives to cut the two ends of the ring knife. By coordinating the scale values ​​with the gear position, accurate tool alignment at both ends can be achieved, which is more convenient to use.
