DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 An asphalt concrete core sample cutting device in this embodiment includes a frame 1, on which is provided a supporting mechanism 2 for supporting the core sample, a pushing mechanism 3 for pushing the core sample to feed, a clamping mechanism 4 for tightening the core sample, a cutting mechanism 5 for cutting the core sample, and a positioning mechanism 6 for pressing the core sample. The core sample is placed on the pushing mechanism 3, and the pushing mechanism 3 pushes the core sample to move close to the cutting mechanism 5. The positioning mechanism 6 accurately positions the moving distance, and the clamping mechanism 4 can clamp and fix the core sample, and the cutting mechanism 5 performs cutting processing.

[0029] A sloped guide seat 7 is also fixed to the left side of the frame 1. The sloped guide seat 7 extends to the bottom where a collection box is placed. The sloped guide seat 7 is a hollow structure and the sloped surface of the sloped guide seat 7 is meshed. A debris collection box is placed below the sloped guide seat 7. The cut part of the core sample slides from the sloped surface of the sloped guide seat 7 into the collection box, and the debris passes through the mesh slope of the sloped guide seat 7 and falls into the debris collection box for collection.

[0030] The support mechanism 2 provides a stable support for the core sample, and at the same time facilitates the pushing mechanism 3 to push the core material to move flexibly, such as Figure 2As shown, the support mechanism 2 includes a pair of support bars 201 fixed on the frame 1, and a plurality of support wheels 202 are rotatably provided on the two support bars 201 via a rotating shaft.

[0031] The support wheels 202 on the two support bars 201 are distributed obliquely and symmetrically, which can provide a stable support for the core material and facilitate the pushing mechanism 3 to push the core sample to move.

[0032] After the core sample is placed on the support wheel 202, the core material can be pushed by the pushing mechanism 3 to control the cutting length of the core material. Figure 3 As shown, the pushing mechanism 3 includes a pushing cylinder 301 fixed on the frame 1 , and a fan-shaped pushing plate 302 is fixed to the output shaft of the pushing cylinder 301 .

[0033] The push cylinder 301 is pushed out, and the fan-shaped push plate 302 can move to the left between the two groups of support wheels 202, and push the core sample to move close to the cutting mechanism 5, so as to control the feeding distance of the core sample.

[0034] After the position of the core sample is adjusted by the fan-shaped push plate 302, the core sample can be firmly clamped by the clamping mechanism 4. Figure 2 As shown, the clamping mechanism 4 includes a support frame 401 fixed on the frame 1, and a pair of clamping cylinders 402 arranged opposite to each other up and down are fixed on the support frame 401. The output ends of the two clamping cylinders 402 are fixed with arc-shaped clamping plates 403. When the two clamping cylinders 402 are pushed out, the two arc-shaped clamping plates 403 can move relative to each other to clamp the core sample.

[0035] A pair of limit rods 404 are fixed on the opposite back sides of the two arc-shaped clamping plates 403, and a limit sleeve 405 corresponding to the limit rod 404 is fixed on the support frame 401. When the arc-shaped clamping plates 403 move up and down, the limit rod 404 moves up and down in the limit sleeve 405 at the same time, and under the guiding action of the limit rod 404 and the limit sleeve 405, the movement of the arc-shaped clamping plates 403 is more stable.

[0036] The two sides of the bottom arc-shaped clamping plate 403 are recessed inward to form a rectangular groove, and the bottom arc-shaped clamping plate 403 is provided with an auxiliary wheel 406 extending into the inside of the rectangular groove through the rotation of the rotating shaft. The setting of the auxiliary wheel 406 can make it easier for the core sample to be pushed out from the bottom arc-shaped clamping plate 403 when the fan-shaped pushing plate 302 pushes the core sample to move. After adjusting the position of the core sample by the fan-shaped pushing plate 302, the bottom arc-shaped clamping plate 403 can be slightly pushed upward, so that the bottom arc-shaped clamping plate 403 and the core sample can fit more closely, and then the top arc-shaped clamping plate 403 moves downward to press the core sample onto the bottom arc-shaped clamping plate 403, so that the core sample can be clamped more firmly.

[0037] After the core sample is clamped, the cutting mechanism 5 can be used for automatic cutting, such as Figure 4As shown, the cutting mechanism 5 includes a rotating motor 501 fixed on the frame 1, the output shaft of the rotating motor 501 is fixed with a driving shaft 502, the outer side of the driving shaft 502 is rotatably provided with a mounting frame 503 through a bearing, a flip cylinder 504 is hinged on the frame 1 through a hinge seat, the output shaft of the flip cylinder 504 is hinged on the mounting frame 503, a rotating shaft 505 is rotatably provided on the mounting frame 503 through a bearing, a blade 506 is fixed at the end of the rotating shaft 505, and the driving shaft 502 and the rotating shaft 505 are connected by a chain transmission structure.

[0038] The chain transmission structure includes multiple transmission sprockets 507 and transmission chains 508 that are simultaneously sleeved on the outside of the multiple transmission sprockets 507. The corresponding transmission sprockets 507 are respectively fixed to the ends of the driving shaft 502 and the rotating shaft 505. Under the transmission action of the transmission sprockets 507 and the transmission chain 508, the driving shaft 502 can simultaneously drive the rotating shaft 505 to rotate.

[0039] The output shaft of the rotating motor 501 drives the driving shaft 502 to rotate. Under the transmission effect of the chain transmission structure, the rotating shaft 505 can rotate synchronously, and the blade 506 can rotate. Figure 4 In the state shown, the flip cylinder 504 contracts, and the mounting frame 503 rotates downward with the driving shaft 502 as the center, which can drive the blade 506 to move toward the side close to the core sample. After moving a certain distance, the core sample cutting can be completed.

[0040] In addition, the positioning mechanism 6 is arranged on the mounting frame 503, and the distance of the core sample is accurately controlled by the positioning mechanism 6 to further improve the cutting accuracy of the core material. Specifically, Figure 4-5 As shown, the positioning mechanism 6 includes an adjusting screw 601 threadedly connected to the mounting frame 503, and a roller frame 602 is rotatably provided at the end of the adjusting screw 601 through a bearing, and a clamping wheel 603 is rotatably provided in the roller frame 602 through a rotating shaft.

[0041] One end of the roller frame 602 extends into the mounting frame 503, and a limiting groove is provided in the mounting frame 503 for only the linear movement of the end of the roller frame 602. The movement direction of the roller frame 602 is limited by the limiting groove. When the adjusting screw 601 rotates, the roller frame 602 can drive the clamping wheel 603 to move horizontally linearly. The cutting distance of the core sample can be adjusted by adjusting the position of the clamping wheel 603.

[0042] By adopting the above-mentioned asphalt concrete core sample cutting device, automatic feeding and automatic cutting of the core sample are realized, and the overall cutting process is smooth and efficient. The specific cutting method is as follows:

[0043] First, place the core sample on the support wheel 202, push the push cylinder 301 out, and the fan-shaped push plate 302 can move to the left between the two groups of support wheels 202, and push the core sample to move a distance close to the cutting mechanism 5 until the end of the core sample is pressed against the pressing wheel 603, and the bottom arc clamping plate 403 can be slightly pushed upward to make the bottom arc clamping plate 403 and the core sample fit more closely, and then the top arc clamping plate 403 moves downward to press the core sample against the bottom arc clamping plate 40 3, the core sample can be firmly clamped between the two arc-shaped clamping plates 403, and then the driving shaft 502 is driven to rotate by the output shaft of the rotating motor 501. Under the transmission action of the chain transmission structure, the rotating shaft 505 can rotate synchronously, and the blade 506 can rotate. Finally, the flip cylinder 504 is retracted, and the mounting frame 503 rotates downward with the driving shaft 502 as the center of the circle, which can drive the blade 506 to move to the side close to the core sample. After moving a certain distance, the core sample can be cut.

[0044] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
