[0016] Compared with the prior art, the present application has at least the following advantages:

[0017] In the above scheme, by setting the clamping assembly, when the test piece is subjected to the bending test, the clamping portions located on both sides of the test piece clamp the test piece, so that the test piece is more stable during testing, and deviation of the test result caused by deviation of the test piece during testing is avoided. Further, when the test piece is broken, the clamping portion rotates the broken test piece to the lower side to achieve automatic release, so that the test piece falls into the hopper. The clamping assembly is linked by the oil control storage rod, and the precise positioning of the limiting column and the clamping groove improves the uniformity of the test piece placement direction and reduces the test deviation rate, thereby reducing the data repeatability error. The cooperation of the buffer plate and the threaded rod can adapt to most specifications of test pieces without the need to replace the clamp. Compared with the traditional single specification clamp, the adaptability is improved.

[0018] The clamping assembly is automatically released by the meshing of the bevel gear and the trigger tooth plate. The collection assembly collects in a step-by-step rotation manner, so that the test cycle of a single set of test pieces is shortened, the efficiency is improved, the broken test pieces and cement slag are separated and collected, the risk of splashing is avoided, the cleaning workload of the operator is reduced, the test cleaning time is shortened, and the safety of the test environment is significantly improved, so that safety accidents such as scratches caused by fragments do not occur.

[0019] By setting the collection assembly, when the broken test piece falls into the hopper under the action of the clamping portion, the test piece falls into the collection frame under the action of the hopper. Since the collection frame is symmetrically provided with two collection frames, when the test piece is broken, the two broken test pieces will fall into the two collection frames respectively, so that the tested test pieces are collected. Further, when the test piece is broken, the cement slag at the broken part will fall into the collection basket, so that the cement slag and the broken test piece are collected separately, and the operator does not need to clean the cement slag frequently or search for the tested test piece.

[0020] By setting the clamping assembly and the collection assembly, after each test piece is tested and broken, the test piece rotates with the first gear shaft. Through the rotation of the test piece, a new collection frame will rotate to the lower side of the hopper, so that different test pieces are collected. When the broken test pieces are collected, the test pieces in the collection frame at the same position are the same sample. When the broken test pieces are subsequently checked, only the test piece in the collection frame at the corresponding position needs to be taken out, so that the process of repeatedly searching for and splicing several broken test pieces is avoided, and the time of the operator for the bending test of the test piece is saved.

[0021] Through the clamping plate of the collection frame, the friction with the test piece is increased by meanses of surface grooves, and the clamping shafts on the side plate and the vertical plate are used to realize the guidance and clamping, so that the test piece after breaking can be firmly fixed, the secondary falling and collision of the test piece in the collection process due to unstable fixation can be effectively avoided, the test piece fragments can be prevented from splashing or additional damage, and the original breaking shape of the test piece after the breaking experiment can be maximally reserved, so that a complete sample basis is provided for subsequent detection.

[0022] By setting the automatic marking assembly, the digital stamp is triggered by the weight of the test piece to complete the transfer printing number of the broken test piece, and the digital stamp number of each collection frame is unique and arranged in order, manual marking is not required, manual operation steps and errors are reduced, the number of each experimental sample is clear, and the corresponding relationship is clear, so that the problem of sample adulteration of different proportion test samples can be effectively avoided, the accuracy of data in subsequent sample comparison and detection work is ensured from the source, and deviation of detection results caused by sample confusion is avoided.

[0023] By setting the color adding roller in the coloring box, the coloring cloth is rotated in a timely manner by driving the motor, and the hollow sponge filled with pigment can continuously supply and attach the pigment to the coloring cloth. Meanwhile, the pigment cylinder slowly penetrates the pigment into the sponge through the hose, so that the coloring cloth is supplied with color and used in a circulating manner. The design does not need to frequently replace the coloring cloth, the pigment supply is stable and controllable, and only a new cylinder needs to be replaced when the pigment in the pigment cylinder is used up, so that the cost of experimental consumables is greatly reduced, the frequency of replacement of consumables is reduced, the continuity of the experimental process is improved, the subsequent efficient promotion of the experiment is facilitated, the overall work efficiency is improved, the broken test piece with a unique number facilitates the comparison of two groups of samples by workers, and the sample information can be quickly identified and the experimental data can be traced when the sample is transported to other detection equipment for further detection. The whole device automatically connects the sample collection, fixation and marking processes, reduces the cumbersome steps of manual intervention, reduces the operation strength of workers, and significantly improves the overall work efficiency of the test piece breaking experiment from sample processing to subsequent detection.

When the first bevel gear 522 rotates, the trigger rod 523 will slide in the inside of the support rod 521, because the bottom of the trigger rod 523 is threadedly connected to the first bevel gear 522, and the top of the trigger rod 523 is slidingly connected to the inside of the support rod 521. When the support rod 521 slides in the inside of the trigger rod 523, the support rod 521 will push against the piston rod of the first oil storage rod 524. When the piston rod of the first oil storage rod 524 is pushed, the first oil storage rod 524 will suck the oil in the second oil storage rod 525 into the inside through the hose. When the oil in the second oil storage rod 525 enters the first oil storage rod 524, the piston rod of the second oil storage rod 525 will contract. When the piston rod of the second oil storage rod 525 contracts, the slide rod of the telescopic rod 534 will contract, and the clamping portions 53 on both sides will gradually move away from the surface of the test piece. When the clamping portions 53 loosen the clamping of the test piece, the two broken test pieces will fall into the two hoppers 11 respectively. When the operator needs to perform the folding resistance test on the next test piece, the first gear shaft 511 on both sides needs to be reversely rotated and restored. When the first gear shaft 511 is reversely rotated, the first bevel gear 522 will be reversely rotated under the action of the trigger tooth plate 23, so that the trigger portion 52 returns to the original position. When the support rod 521 returns to the vertical state, the clamping grooves 512 of the clamping plates on both sides of the first gear shaft 511 will be re-coupled with the limiting columns 22.

[0051] In this embodiment, when the test piece is subjected to the folding resistance test, the clamping portions 53 on both sides of the test piece will clamp the test piece, so that the test piece is more stable during the test, and deviation of the test result caused by deviation of the test piece during the test is avoided. Further, when the test piece is broken, the clamping portions 53 can automatically release when the broken test piece is rotated to the lower side, so that the test piece falls into the hopper 11.

[0052] As an embodiment in this embodiment, as Figure 3 and Figures 11 to 13As shown, the collecting assembly 6 comprises a collecting frame 61, both ends of the collecting frame 61 are rotatably connected to the rotating plate 62, one side of the rotating plate 62 is fixedly connected with a second bevel gear 621, one side of the second bevel gear 621 is meshedly connected with a third bevel gear 63, one side of the third bevel gear 63 is fixedly connected with a gear, the third bevel gear 63 is connected with a transmission gear 641 of a third gear shaft 64 through the gear, the upper sides of the two sides of the collecting frame 61 are rotatably connected to the rotating plate 62, the opening of the collecting frame 61 is vertically upward, the collecting frame 61 is annularly arranged between the two rotating plates 62, both ends of the third gear shaft 64 are provided with gears, both ends of the third gear shaft 64 are connected with both ends of the second gear shaft 513 through a chain, the inner ring of the transmission gear 641 is provided with a ratchet wheel, the surface of the third gear shaft 64 is provided with a pawl, the transmission gear 641 and the third gear shaft 64 are connected through the ratchet wheel and the pawl, both sides of the collecting basket 12 are rotatably connected with the rotating plate 62, the opening at the bottom of the hopper 11 is located directly above the opening of the collecting frame 61, the collecting basket 12 is located directly below the loading head 41, the collecting basket 12 is made of stainless steel and is provided with a detachable filter screen at the bottom, when the first gear shaft 511 is rotated by the broken test piece, the gear on the first gear shaft 511 will drive the second gear shaft 513 to rotate through the chain, when the second gear shaft 513 rotates, the third gear shaft 64 below will be driven to rotate through the chain, when the third gear shaft 64 rotates, the transmission gear 641 will be driven to rotate, when the transmission gear 641 rotates, the third bevel gear 63 below will be driven to rotate, thereby driving the second bevel gear 621 to rotate, when the second bevel gear 621 rotates, the rotating plate 62 will be driven to rotate, so that the collecting frame 61 rotates to the lower side of the hopper 11, then when the first bevel gear 522 contacts the trigger toothed plate 23, so that the clamping portion 53 is separated from the surface of the test piece, the broken test piece will fall into the hopper 11 and then fall into the collecting frame 61 below, when the operator performs the next test for the test piece, the second gear shaft 513 will drive the third gear shaft 64 to rotate, when the third gear shaft 64 rotates, since the third gear shaft 64 and the transmission gear 641 are connected through the ratchet wheel and the pawl, at this time, the third gear shaft 64 which rotates in the opposite direction will not drive the transmission gear 641 to rotate, and when the broken test piece falls, the rotating plate 62 will rotate again, so that the collecting frame 61 containing the broken test piece moves away from the lower side of the hopper 11, and the empty collecting frame 61 moves to the lower side of the hopper 11, ready to collect the broken test piece.

[0053] In the embodiment, when the broken test piece falls into the hopper 11 under the action of the clamping part 53, the test piece will fall into the collection frame 61 under the action of the hopper 11. Since the collection frame 61 is symmetrically provided with two, when the test piece is broken, the two broken test pieces will fall into the two collection frames 61 respectively, so that the collection of the tested test piece is realized. Further, when the test piece is subjected to the bending test, a plurality of test pieces in a group of test piece samples will be subjected to the bending test. After each test piece is broken in the test, a new collection frame 61 will be rotated to be below the hopper 11, so that different test pieces can be collected. When the broken test pieces are collected, the test pieces in the same position in the collection frame 61 are the same sample. When the broken test pieces are subjected to subsequent inspection, only the test piece in the corresponding position in the collection frame 61 needs to be taken out, so that the process of corresponding the several broken test pieces one by one in the subsequent inspection of the broken test pieces is avoided, the time of the operator for the bending test of the test piece is saved, the broken test piece can be firmly fixed, the secondary falling and collision of the test piece in the collection process due to unstable fixation are effectively avoided, the situation of test piece fragments splashing or additional damage is reduced, and the original broken shape of the test piece after the breaking test is maximally reserved, so that a complete sample basis is provided for subsequent detection.

[0054] As an embodiment in the embodiment, as shown in Figure 11 、 Figure 12 and Figures 14 to 16 , the automatic marking assembly 7 comprises an outer frame 70 mounted on the inner wall of the two sides of the collection frame 61. The inner side of the outer frame 70 is rotationally connected with a clamping plate 701. The top front end of the outer frame 70 is provided with a side plate 702. The top of the side plate 702 is mounted with a vertical plate 703. The inner side of the side plate 702 is mounted with a clamping shaft 704. The top front end of the outer frame 70 is mounted with a color box 705. The inner wall of the color box 705 is rotationally connected with a color roller 706. The middle part of the color roller 706 is hollow and filled with sponge. A plurality of small holes 707 are formed in one side of the color roller 706. A pigment cylinder 708 is mounted on one side of the color box 705. The pigment cylinder 708 is connected with the hollow part of the color roller 706 through a hose. The outer side of the side plate 702 is inserted with a first piston cylinder 710. The end of the first piston cylinder 710 is mounted with a digital seal 711. The bottom end of the clamping plate 701 is mounted with a second piston cylinder 712. The first piston cylinder 710 is connected with the second piston cylinder 712 through a hose. The top and bottom of the color box 705 are inserted with a color cloth 709. The left side of the color cloth 709 passes around the surface of the color roller 706, and the remaining part of the color cloth 709 is wound on the outer surface of the side plate 702. The surface of the digital seal 711 is engraved with a convex digital number. The inner side of the color cloth 709 is tightly attached to the surface of the digital seal 711. The inner wall of the second piston cylinder 712 is mounted with a spring.

[0055] In the embodiment, the automatic marking assembly 7 triggers the seal stamping by the weight of the test piece, the number is unique and arranged in order, compared with sample confusion and traditional manual marking, it is convenient for subsequent comparison and data tracing, it is suitable for batch test scene, the pigment barrel 708 adopts plug-in design, and is circularly used with the colored cloth 709, without frequent replacement of consumables, and the consumable cost is low.

[0056] The working principle of the technical scheme provided by the application is as follows:

[0057] When the operator performs the bending test on the test piece, the operator needs to place the treated test piece on the mounting frame 1, so that the two ends of the test piece are located on the two placing blocks 2 respectively.

[0058] When the test piece is placed on the placing block 2, the operator needs to rotate the threaded rod 533 by a tool, when the threaded rod 533 is rotated, the buffer plate 532 will extend from the clamping plate 531 and clamp the side of the test piece, when the two sides of the test piece are clamped by the buffer plate 532, at this time, the operator can extrude the loading head 41 above the test piece by controlling the hydraulic cylinder 4, when the test piece is broken by the loading head 41, at this time, under the action of gravity, the broken half test piece will rotate with the clamping plate 531, and drive the first gear shaft 511 to rotate through the supporting rod 521, when the first gear shaft 511 rotates, the clamping groove 512 of the clamping plate on both sides of the first gear shaft 511 will be separated from the limiting column 22, at the same time, the test piece will rotate around the rotating hole 21 with the clamping part 53, with the rotation of the first gear shaft 511, when the supporting rod 521 rotates to the trigger tooth plate 23, the first bevel gear 522 will be meshed and connected with the trigger tooth plate 23, when the supporting rod 521 continues to rotate, the first bevel gear 522 will rotate under the action of the trigger tooth plate 23, when the first bevel gear 522 rotates, since the bottom of the trigger rod 523 is threadedly connected with the first bevel gear 522, and the top of the trigger rod 523 is slidingly connected in the inside of the supporting rod 521, the trigger rod 523 will slide in the inside of the supporting rod 521, when the supporting rod 521 slides in the inside of the trigger rod 523, the supporting rod 521 will abut against the piston rod of the first oil storage rod 524, when the piston rod of the first oil storage rod 524 is pushed, the first oil storage rod 524 will suck the oil in the second oil storage rod 525 into the inside through the hose, when the oil in the second oil storage rod 525 enters the first oil storage rod 524, the piston rod of the second oil storage rod 525 will contract, when the piston rod of the second oil storage rod 525 contracts, the sliding rod of the telescopic rod 534 will contract, when the sliding rod of the telescopic rod 534 contracts, the clamping parts 53 on both sides will gradually move away from the surface of the test piece, when the clamping parts 53 release the clamping of the test piece, the two broken test pieces will fall into the two funnels 11 respectively.

[0059] When the operator needs to perform a next test piece for the bending test, the first gear shaft 511 on both sides needs to be reversed and restored. When the first gear shaft 511 is reversed, the first bevel gear 522 will be reversed under the action of the trigger tooth plate 23, so that the trigger part 52 returns to the original position. When the support rod 521 returns to the vertical state, the clamping groove 512 of the clamping plate on both sides of the first gear shaft 511 will be re-coupled with the limiting column 22. When the test piece is subjected to the bending test, the clamping part 53 on both sides of the test piece will clamp the test piece, so that the test piece is more stable during testing, and the test piece is prevented from deviating during testing, which causes the deviation of the test result. Further, when the test piece is broken, the clamping part 53 will rotate the broken test piece to the lower side, which can realize automatic release, so that the test piece falls into the hopper 11. When the first gear shaft 511 is rotated by the broken test piece, the gear on the first gear shaft 511 will rotate the second gear shaft 513 through the chain. When the second gear shaft 513 rotates, it will drive the third gear shaft 64 below through the chain. When the third gear shaft 64 rotates, it will drive the transmission gear 641 to rotate. When the transmission gear 641 rotates, it will drive the third bevel gear 63 below to rotate, thereby driving the second bevel gear 621 to rotate. When the second bevel gear 621 rotates, it will drive the rotating plate 62 to rotate, so that the collecting frame 61 rotates to the lower side of the hopper 11. Then, when the first bevel gear 522 contacts the trigger tooth plate 23, thereby separating the clamping part 53 from the surface of the test piece, the broken test piece will fall into the hopper 11 and then fall into the collecting frame 61 below from the hopper 11.

[0060] When the operator performs the next test piece of the bending test, the second gear shaft 513 will rotate with the third gear shaft 64, when the third gear shaft 64 rotates, due to the cooperation between the ratchet and the pawl, the third gear shaft 64 will not rotate the transmission gear 641, and when the broken test piece falls, the rotating plate 62 will rotate again, so that the collecting frame 61 containing the broken test piece is away from the lower side of the funnel 11, and the empty collecting frame 61 moves to the lower side of the funnel 11, ready to collect the broken test piece, when the broken test piece falls under the action of the clamping part 53, the test piece will fall into the collecting frame 61 under the action of the funnel 11, since the collecting frame 61 is symmetrically provided with two, when the test piece is broken, the two broken test pieces will fall into the two collecting frames 61 respectively, realizing the collection of the tested test piece, further, during the bending test of the test piece, a group of test piece samples usually have multiple test pieces, after each test piece is tested and broken, a new collecting frame 61 will rotate to the lower side of the funnel 11, realizing the collection of different test pieces, and when collecting the broken test piece, the test piece in the collecting frame 61 at the same position is the same sample, when checking the broken test piece, only the test piece in the collecting frame 61 at the corresponding position needs to be taken out, avoiding the process of corresponding each broken test piece one by one during the subsequent inspection of the broken test piece, saving the time of the operator for the bending test of the test piece.

[0061] Since the size of the collecting frame 61 is designed according to the size of the experimental test piece, and can be assembled by bolts at the bottom according to the actual use, after the broken test piece falls vertically from the funnel 11 into the collecting frame 61, the weight of the test piece will push the clamping plate 701 inside the collecting frame 61 outward, since the surface of the clamping plate 701 is provided with many grooves for increasing the friction to prevent the test piece from falling, and the test piece falling is guided and clamped by the clamping shaft 704 on the side plate 702 and the vertical plate 703; when the clamping plate 701 is pushed outward, the second piston cylinder 712 at the back is pushed, the oil in the second piston cylinder 712 is extruded into the hose and transmitted into the first piston cylinder 710, the first piston cylinder 710 is pushed by the oil to push the digital seal 711 outward, the digital convex part of the digital seal 711 extrudes the color cloth 709, and the pigment on the back of the color cloth 709 is pressed on the broken test piece, the broken test piece after the test is numbered, the digital seals 711 in the automatic marking assembly 7 inside each collecting frame 61 are different, arranged in order, and finally the staff compares the two groups of broken test pieces with the number printed on them, and facilitates further detection on other inspection equipment, avoiding the deviation of the detection result caused by the mixing of test pieces with different proportions.

[0062] At the same time, since the coloring cloth 709 is closely attached to the coloring box 705, the coloring roller 706 is installed in the coloring box 705 through the driving motor, the driving motor rotates once in a period of time, drives the coloring cloth 709 to rotate a circle, and the dry pigment is wetted, and the new pigment is guided to the surface of the coloring cloth 709. At this time, the sponge in the hollow part of the coloring roller 706 in the coloring box 705 is full of the pigment, and the coloring cloth 709 is adhered to the coloring cloth 709 through the small hole 707, so that the coloring cloth 709 has the pigment on the surface. At the same time, the pigment cylinder 708 slowly penetrates into the sponge in the coloring roller 706 through the hose, and the pigment is supplemented in the circulation of the coloring cloth 709. The circulation is used until the pigment in the pigment cylinder 708 is used up, and a new pigment cylinder 708 is directly replaced.

[0063] When the sample with the marked number is taken, the spring in the second piston cylinder 712 drives the second piston cylinder 712 to reset, and the first piston cylinder 710 and the digital seal 711 are pulled back through the oil liquid conduction, so that the next new sample is fixed and sealed.
