Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building material crushing, in particular to a waste building detection material recycling device and method. BACKGROUND

[0002] Building material detection is an important link in building construction, and its quality determines the safety performance, service life and environmental protection level of the building. As one of the samples for building material performance detection, concrete test blocks are used to detect various properties of concrete and are an important basis for evaluating concrete quality and ensuring structural safety. The detection items include cubic compressive strength, axial compressive strength, bending strength, impermeability, and frost resistance. After completing the performance detection, the concrete test blocks are usually treated as construction waste because the detection process may cause structural damage, the material properties have changed, or the test blocks themselves are one-time detection samples. For concrete test blocks that are not chemically contaminated, they can be processed by crushing and screening and used as recycled aggregates for non-structural parts such as low-strength concrete, mortar, cushion, and roadbed filling, or for making bricks and blocks.

[0003] A toothed roll crusher is a device for crushing concrete, which uses two or more relatively rotating toothed rolls to perform extrusion, splitting, and shearing on the material to achieve crushing.

[0004] For example, the patent document with publication number CN119237078B discloses a toothed roll crusher. The toothed roll crusher has a housing with a toothed roll assembly, which includes a main shaft, a first tooth seat, and a second tooth seat. The first tooth seat and the second tooth seat are both mounted on the main shaft, and the second tooth seat has an installation slot with a tooth tip assembly inside. The material is placed into the housing through the feed port, and the driving motor is operated to drive the two main shafts to rotate in the housing, thereby driving the two toothed roll assemblies to rotate towards each other to crush the material placed.

[0005] When using the above toothed roll crusher to crush concrete test blocks, in order to fully crush the concrete test blocks and achieve the target particle size, the gap between the two crushing rolls usually needs to be adjusted to a small size, which directly leads to a serious limitation of the speed of the concrete test blocks in the clamping area between the two rolls, causing large concrete test blocks to be unable to quickly and smoothly enter the crushing chamber, resulting in low processing efficiency of the equipment. SUMMARY

[0006] Therefore, the present application provides a waste building detection material recycling device and method to solve the technical problem of low crushing efficiency caused by the small distance between the two crushing rolls in the prior art.

[0007] To solve the above technical problems, on the one hand, the application provides a waste building detection material recycling device, which comprises a shell, a crushing roller rotatably connected in the shell, the crushing roller being driven by a driving assembly, a variable roller one and a variable roller two being rotatably connected in the shell, the variable roller one and the variable roller two both being hollow cylindrical structures;

[0008] A cam one is rotatably connected in the variable roller one, a plurality of roller teeth one are slidably arranged on the side wall of the variable roller one, a reset spring one is connected between the roller teeth one and the variable roller one, and the variable roller one is driven by a driving piece one;

[0009] A cam two is rotatably connected in the variable roller two, a plurality of stop blocks are hingedly arranged on the side wall of the variable roller two, a plurality of roller teeth two are arranged on the stop blocks, a reset spring two is connected between the stop blocks and the variable roller two, and the variable roller two is driven by a driving piece two;

[0010] The convex part of the cam one faces the crushing roller, the convex part of the cam two faces the variable roller one, the cam one can push the roller teeth one to move, and the cam two can push the stop blocks to move, so that the roller teeth two are located above the roller teeth one and the two are close to each other.

[0011] Through the above technical scheme, the driving piece one drives the variable roller one to rotate, the convex part of the cam one pushes the roller teeth one to extend, that is, to move away from the axis of the variable roller one, the driving piece two drives the variable roller two to rotate, the convex part of the cam two pushes the stop blocks to extend, that is, to move away from the axis of the variable roller two, so that the roller teeth two are located above the roller teeth one and the two are close to each other, forming an interlaced preliminary crushing area. When the roller teeth one extend, the concrete test block is hit and crushed, and the roller teeth one at other positions are retracted under the elastic force of the reset spring one. When the roller teeth two extend with the stop blocks, the concrete test block hit by the roller teeth one is hit on the roller teeth two, improving the crushing effect. The angle of the stop block can be adjusted, when the stop block extends, it can block the splashing concrete test block and make it fall on the crushing roller for crushing.

[0012] The driving assembly drives the crushing roller to rotate, and the preliminarily crushed concrete test block falls on the crushing roller below, and under the cooperation of the variable roller two and the crushing roller, the crushing roller crushes the preliminarily crushed concrete test block again.

[0013] The application preliminarily crushes the large concrete test block to a size suitable for efficient feeding and fine crushing, solving the technical problem that in order to ensure the crushing effect of the concrete test block, the distance between the two crushing rollers is small, causing the concrete test block to slowly feed into the clamping area between the two crushing rollers, resulting in low crushing efficiency of the concrete test block. At the same time, after the preliminary crushing of the concrete test block, the surface is rough and forms uneven texture, when the roller teeth of the subsequent crushing roller contact, the friction force of the contact surface increases, which is conducive to improving the crushing efficiency.

[0014] Preferably, one side of the crushing roller is provided with an auxiliary roller driven by the driving assembly, and a first discharging channel is left between the auxiliary roller and the crushing roller, and a second discharging channel is left between the crushing roller and the variable roller two.

[0015] Through the above technical scheme, after the preliminary crushing by the variable roller one and the variable roller two, the sizes of the concrete test blocks are different, and the concrete test blocks with smaller sizes can directly pass through the first discharging channel to enter the subsequent process, avoiding energy waste caused by excessive crushing. The concrete test blocks with larger sizes cannot enter the first discharging channel, and are guided to the second discharging channel between the crushing roller and the auxiliary roller with the accumulation of the concrete test blocks with larger sizes and the rotation of the crushing roller, and are subjected to targeted secondary crushing through the extrusion and shearing action of the two, so that the particle size of the crushed concrete test blocks is uniform. Through the arrangement of the two discharging channels, the occupation of the tooth roller clamping area by the concrete test blocks with smaller sizes can be reduced, which is beneficial to accelerating the feeding speed of the concrete test blocks with larger sizes in the clamping area between the rollers, thereby improving the crushing efficiency.

[0016] Preferably, a discharging channel is left between the variable roller two and the variable roller one, the variable roller two is slidingly connected in the shell, and a linear driver for driving the variable roller two to move back and forth is arranged in the shell to adjust the width of the discharging channel.

[0017] Through the above technical scheme, the linear driver drives the variable roller two to move back and forth, drives the variable roller two to swing, and then adjusts the width of the discharging channel. Through the left and right small-amplitude swing, it is beneficial to breaking the stress balance between the concrete test blocks, so that the test block group which may form an arch shape is loose and separated, thereby reducing the blockage of the discharging channel. At the same time, the swing of the variable roller two is beneficial to applying a downward impact force to the contacted concrete test blocks, giving them initial kinetic energy, so that they smoothly enter the gap between the tooth one and the tooth two, thereby improving the feeding speed and improving the crushing efficiency.

[0018] Preferably, a plurality of tooth grooves are arranged on the circumference of the variable roller one, the tooth one is slidingly arranged in the tooth groove, a plurality of tooth grooves form a tooth groove group, and a plurality of tooth groove groups are arranged on the side wall of the variable roller one in the axial direction.

[0019] Through the above technical scheme, the plurality of tooth grooves are uniformly distributed on the circumference of the variable roller one, and when the tooth groove moves to the convex part of the cam one, the tooth one in the tooth groove protrudes to crush the concrete test blocks. The tooth one is arranged in the axially spaced tooth groove group, and the tooth one in the tooth groove group collectively crushes the concrete test blocks, thereby strengthening the stability and safety of the crushing process.

[0020] Preferably, the upper part of the shell is provided with a feeding hopper, and the lower part of the shell is provided with a discharging hopper.

[0021] Through the above technical scheme, the concrete test block enters into the shell from the feeding hopper, is discharged from the discharging hopper after primary crushing and secondary crushing.

[0022] Preferably, the driving member one comprises a driving motor one installed in the shell, and a synchronous belt transmission structure one drivingly connected to the output shaft of the driving motor one and the variable roller one.

[0023] Through the above technical scheme, the driving motor one drives the synchronous belt transmission structure one to rotate, and further drives the variable roller one to rotate, since the cam one is rotatably installed in the variable roller one, after the variable roller one rotates, the convex part of the cam one intermittently pushes the roller teeth one on the variable roller one to extend, so that the intermittent crushing of the concrete test block is realized.

[0024] Preferably, the driving member two comprises a driving motor two installed in the shell, and a synchronous belt transmission structure two drivingly connected to the output shaft of the driving motor two and the variable roller two.

[0025] Through the above technical scheme, the driving motor two drives the synchronous belt transmission structure two to rotate, and further drives the variable roller two to rotate, since the cam two is rotatably installed in the variable roller two, after the variable roller two rotates, the convex part of the cam two intermittently pushes the stopper on the variable roller two to extend, after the roller teeth one crushes the concrete test block, the roller teeth two are hit by the concrete test block when the roller teeth two extend with the stopper, so that the crushing effect is improved.

[0026] Preferably, the shell is slidingly connected with an adjusting block, the adjusting block is rotatably connected with a tensioning wheel, the tensioning wheel is drivingly connected with the synchronous belt transmission structure two, and the adjusting block and the shell are connected with a reset spring three.

[0027] Through the above technical scheme, the tensioning wheel is in contact with the synchronous belt transmission structure two, when the variable roller two moves to cause the synchronous belt transmission structure two to relax, the reset spring three will push the adjusting block to slide, and drive the tensioning wheel to tightly press the synchronous belt transmission structure two, so that the relaxation amount of the synchronous belt transmission structure two is automatically compensated. When the variable roller two moves reversely to cause the synchronous belt transmission structure two to be tight, the tensioning wheel will be pushed and squeezed by the synchronous belt transmission structure two, the reset spring three is compressed through the adjusting block, so that the belt body is prevented from being broken due to excessive stretching.

[0028] Preferably, the driving assembly comprises a driving motor three installed on the shell, a driving gear installed on the output shaft of the driving motor three, a driven gear one installed on the auxiliary roller, and a driven gear two installed on the crushing roller, the driving gear, the driven gear two and the driven gear one are drivingly engaged in sequence.

[0029] Through the above technical scheme, the driving motor three drives the driving gear to rotate, since the driving gear, the driven gear two and the driven gear one are drivingly engaged in sequence, the driven gear one and the driven gear two are further driven to rotate, so that the auxiliary roller and the crushing roller are driven to rotate.

[0030] In another aspect, the present application provides a waste building detection material recycling method using the waste building detection material recycling device described above, comprising the following steps:

[0031] Step one: the driving part one drives the variable roller one to rotate, and the convex part of the cam one intermittently pushes the roller teeth one on the variable roller one to protrude, so as to hit and break the material falling from the feeding channel;

[0032] Step two: the driving part two drives the variable roller two to rotate, and the convex part of the cam two pushes the stop block on the variable roller two to protrude, so that the material hit by the roller teeth one is impacted on the roller teeth two;

[0033] Step three: the driving assembly drives the crushing roller to rotate, and the preliminarily crushed material is crushed again by the crushing roller.

[0034] Through the above technical scheme, the roller teeth one and the roller teeth two preliminarily crush the concrete test block, which is beneficial to improve the feeding speed of the crushing roller when crushing the concrete test block for the second time, thereby being beneficial to improve the crushing efficiency. Meanwhile, after the preliminary crushing of the concrete test block, the surface is rough and forms uneven textures, so that when the concrete test block contacts with the roller teeth of the subsequent crushing roller, the friction force of the contact surface is increased, which is beneficial to improve the crushing efficiency.

[0035] The beneficial effects of the above technical scheme of the present application are as follows:

[0036] 1. The present application preliminarily crushes the large concrete test block to a size suitable for efficient feeding and fine crushing, which solves the technical problem that the distance between the two crushing rollers is small to ensure the crushing effect of the concrete test block, and is beneficial to improve the crushing efficiency. Meanwhile, after the preliminary crushing of the concrete test block, the surface is rough and forms uneven textures, so that when the concrete test block contacts with the roller teeth of the subsequent crushing roller, the friction force of the contact surface is increased, which is also beneficial to improve the crushing efficiency.

[0037] 2. After the preliminary crushing by the variable roller one and the variable roller two, the concrete test block with a smaller size can be directly discharged through the discharge channel one, and the concrete test block with a larger size cannot enter the discharge channel one, so that the concrete test block with a larger size is guided to the discharge channel two and is crushed for the second time in the discharge channel two. The present application can reduce the occupation of the tooth roller clamping area by the concrete test block with a smaller size, which is beneficial to speed up the feeding rate of the concrete test block with a larger size into the clamping area between the rollers, thereby being beneficial to improve the crushing efficiency.

[0038] 3. The variable roller II of the present invention can swing slightly, which helps to break the force balance between concrete test blocks, loosening and separating the test block group that might otherwise form an arch shape. This helps to reduce the blockage of the feeding channel and also helps to apply a downward impact force to the contacting concrete test blocks, giving them initial kinetic energy and allowing them to smoothly enter the gap between roller teeth I and roller teeth II, thereby improving the feeding speed and crushing efficiency.

Figures 1-7 The technical solutions of the embodiments of the present application are described clearly and completely.

[0048] Embodiment

[0049] The present embodiment provides a waste building detection material recycling device, as shown in Figure 1 and Figure 2 , which comprises a shell 1 and a crushing roller 2.

[0050] As shown in Figure 1 and Figure 2 , an inlet hopper 11 is arranged above the shell 1, and an outlet hopper 12 is arranged below the shell 1. After the concrete test block 6 enters the shell 1 from the inlet hopper 11, it is crushed and then discharged from the outlet hopper 12.

[0051] As shown in Figure 1 and Figure 2 , the crushing roller 2 is rotationally connected in the shell 1, and a plurality of crushing teeth 21 are arranged on the circumferential side of the crushing roller 2.

[0052] As shown in Figure 2 , a variable roller one 3, a variable roller two 4 and an auxiliary roller 5 are also rotationally connected in the shell 1.

[0053] As shown in Figure 2 , the auxiliary roller 5 is located on the left side of the crushing roller 2, the variable roller one 3 and the variable roller two 4 are both located above the crushing roller 2, and the variable roller one 3 is located on the left side of the variable roller two 4. The axes of the crushing roller 2, the variable roller one 3, the variable roller two 4 and the auxiliary roller 5 all extend in the front-rear direction.

[0054] As shown in Figure 2 , the variable roller one 3 and the variable roller two 4 are both hollow cylindrical structures, and a discharging passage is left between the variable roller one 3 and the variable roller two 4, which is below the inlet hopper 11.

[0055] As shown in Figure 3 and Figure 7 , a plurality of roller tooth grooves 31 are arranged on the circumference of the variable roller one 3, and the plurality of roller tooth grooves form a roller tooth groove group. Along the axial direction of the variable roller one 3, a plurality of roller tooth groove groups are arranged on the side wall of the variable roller one 3.

[0056] As shown in Figure 3 and Figure 7 , a roller tooth one 32 is slidingly connected in the roller tooth groove 31 and along the radial direction of the variable roller one 3, and the roller tooth one 32 is T-shaped. The roller tooth one 32 comprises a tooth tip portion 321 away from the axis of the variable roller one 3 and a connecting portion 322 close to the axis of the variable roller one 3.

[0057] As shown in Figure 3 and Figure 7 , the connecting part 322 and the inner wall of the variable roller one 3 are connected with a reset spring one 33. The variable roller one 3 is rotatably connected with a cam one 34, the cam one 34 penetrates the variable roller one 3, and is fixedly connected between the variable roller one 3 and the shell 1.

[0058] As shown in Figure 2 , the convex part of the cam one 34 faces the crushing roller 2, and the cam one 34 can push the roller tooth one 32 to move along the radial direction of the variable roller one 3 and away from the axis of the variable roller one 3. When the roller tooth one 32 is extended, the tooth tip part 321 is gradually inclined to the side away from the axis of the variable roller one 3 from top to bottom, which facilitates the impact on the concrete test block 6 falling from the discharging channel.

[0059] As shown in Figure 1 and Figure 2 , the rotation of the variable roller one 3 is driven by a driving part one 35, which includes a driving motor one 351 and a synchronous belt transmission structure one 352.

[0060] As shown in Figure 1 and Figure 2 , the driving motor one 351 is installed in the shell 1. The synchronous belt transmission structure one 352 includes pulleys one installed on the driving motor one 351 and the variable roller one 3 respectively, and a synchronous belt one connected in transmission between the two pulleys one. The driving motor one 351 drives the synchronous belt transmission structure one 352 to rotate, thereby driving the variable roller one 3 to rotate.

[0061] As shown in Figure 1 and Figure 2 , the concrete test block 6 falls from the feeding hopper 11 into the discharging channel, and the driving part one 35 drives the variable roller one 3 to rotate. Since the cam one 34 is rotatably installed inside the variable roller one 3, after the variable roller one 3 rotates, the convex part of the cam one 34 intermittently pushes the roller tooth one 32 on the variable roller one 3 to extend, i.e. to move to the side away from the axis of the variable roller one 3, thereby impacting and crushing the concrete test block 6 falling from the discharging channel.

[0062] As shown in Figure 3 and Figure 6 , the variable roller two 4 is provided with four installation grooves 41 on the circumferential side, the installation grooves 41 extend along the axial direction of the variable roller two 4, and the installation grooves 41 are hingedly connected with a stop block 43 through a hinge shaft 42, the axis of the hinge shaft 42 is parallel to the axis of the variable roller two 4, and the stop block 43 and the installation groove 41 are connected with a reset spring two 44, the reset spring two 44 is a torsion spring.

[0063] As shown in Figure 3As shown, the two faces of the block 43 close to the hinge shaft 42 are both arc faces, the arc face far from the axis of the variable roller two 4 is marked as arc face one 431, and the arc face close to the axis of the variable roller two 4 is marked as arc face two 432, a plurality of teeth two 45 are arranged on the arc face one 431.

[0064] As shown in Figure 2 and Figure 4 shown, two mounting frames 13 are arranged in the shell 1, and the two ends of the variable roller two 4 are rotatably connected to the two mounting frames 13. A cam two 46 is rotatably connected in the variable roller two 4 and fixedly connected to the mounting frame 13, the convex part of the cam two 46 faces the variable roller one 3, and the end of the arc face two 432 far from the hinge shaft 42 abuts against the cam two 46.

[0065] As shown in Figure 1 and Figure 2 shown, the rotation of the variable roller two 4 is driven by a driving member two 7, and the driving member two 7 includes a driving motor two 71 and a synchronous belt transmission structure two 72.

[0066] As shown in Figure 2 and Figure 4 shown, the driving motor two 71 is installed in the shell 1. The synchronous belt transmission structure two 72 includes pulleys two 721 installed on the driving motor two 71 and the variable roller two 4 respectively, and a synchronous belt two 722 in transmission connection with the two pulleys two 721. The driving motor two 71 drives the synchronous belt transmission structure two 72 to rotate, thereby driving the variable roller two 4 to rotate.

[0067] As shown in Figures 1-3 shown, the driving member two 7 drives the variable roller two 4 to rotate, since the cam two 46 is rotatably installed in the variable roller two 4, after the variable roller two 4 rotates, the convex part of the cam two 46 pushes the block 43 to rotate around the hinge shaft 42, and the block 43 extends, that is, moves to the side far from the axis of the variable roller two 4. When the teeth one 32 and the block 43 both extend, the teeth two 45 are located above the teeth one 32 and approach the teeth one 32.

[0068] As shown in Figure 2 and Figure 3 shown, when the block 43 extends, the concrete test block 6 hit by the teeth one 32 hits the teeth two 45, thereby improving the crushing effect. Since the angle of the block 43 is adjustable, when the block 43 extends, the splashed concrete test block 6 can be blocked and falls on the crushing roller 2 for crushing.

[0069] In this embodiment, as shown in Figure 2 , the variable roller one 3 and the variable roller two 4 both rotate counterclockwise, and the crushing roller 2 rotates clockwise.

[0070] As shown in Figure 4As shown in the drawings, the shell 1 is provided with two sliding blocks 14 and two sliding rails 15, the sliding block 14 is slidingly connected to the sliding rail 15, the length direction of the sliding rail 15 is perpendicular to the axial direction of the variable roller two 4, and the two sliding rails 15 are parallelly arranged at the two ends of the variable roller two 4. The sliding block 14 is provided with a sliding rod 16, the axis of the sliding rod 16 extends in the up-down direction, and the mounting frame 13 is slidingly connected to the sliding rod 16 in the up-down direction.

[0071] As shown in the drawings, Figure 2 and Figure 4 The shell 1 is provided with two linear drives 17, and the linear drive 17 is a pneumatic cylinder or a hydraulic cylinder. The two linear drives 17 drive the two sliding blocks 14 to slide back and forth in the two sliding rails 15, thereby driving the mounting frame 13 and the variable roller two 4 to slide back and forth, that is, the variable roller two 4 moves away from or approaches one side of the variable roller one 3.

[0072] As shown in the drawings, Figure 2 and Figure 4 The linear drive 17 drives the sliding block 14 to move back and forth, thereby driving the variable roller two 4 to swing left and right, so as to adjust the width of the discharging channel. Through the small amplitude swing of the variable roller two 4, it is beneficial to break the stress balance between the concrete test blocks 6, so that the test block group which may originally form an arch shape is loose and separated, thereby facilitating the reduction of the blockage of the discharging channel. In addition, the swing of the variable roller two 4 is beneficial to exert a downward impact force on the contacted concrete test blocks 6, imparting initial kinetic energy to them, so that the concrete test blocks 6 smoothly enter the gap between the tooth one 32 and the tooth two 45, thereby facilitating the improvement of the feeding speed and the crushing efficiency.

[0073] As shown in the drawings, Figure 2 and Figure 4 The roller shaft of the variable roller one 3 and the roller shaft of the auxiliary roller 5 are both rotationally connected to the connecting piece one 51, the roller shaft of the auxiliary roller 5 and the roller shaft of the crushing roller 2 are both rotationally connected to the connecting piece two 52, and the roller shaft of the crushing roller 2 and the roller shaft of the variable roller two 4 are both rotationally connected to the connecting piece three 53. The connecting piece one 51, the connecting piece two 52 and the connecting piece three 53 are all plate-shaped structures.

[0074] As shown in the drawings, Figure 4 The shell 1 is provided with a sliding groove 73 near the synchronous belt two 722, and an adjusting block 74 is slidingly arranged in the sliding groove 73, the sliding direction of the adjusting block 74 is consistent with the sliding direction of the sliding block 14. The adjusting block 74 is rotationally connected with a tension pulley 75, the tension pulley 75 is in transmission connection with the synchronous belt two 722, and the adjusting block 74 and the sliding groove 73 are connected with a reset spring three 76.

[0075] As shown in the drawings, Figure 2 and Figure 4As shown, the tension wheel 75 is in transmission connection with the synchronous belt two 722, when the variable roller two 4 moves to cause the synchronous belt two 722 to relax, the reset spring three 76 will push the adjusting block 74 to slide, drive the tension wheel 75 to press the synchronous belt two 722, automatically compensate the relaxation amount of the synchronous belt two 722. When the variable roller two 4 moves reversely to make the synchronous belt transmission structure two 72 tight, the tension wheel 75 will be pushed by the synchronous belt two 722, through the adjusting block 74 to compress the reset spring three 76, avoid the belt body to break due to excessive stretching.

[0076] As shown in Figure 1 and Figure 5 , the auxiliary roller 5 and the crushing roller 2 are driven by the driving assembly 8, the driving assembly 8 includes the driving motor three 81, the driving gear 82, the driven gear one 83 and the driven gear two 84.

[0077] As shown in Figure 1 and Figure 5 , the driving motor three 81 is arranged in the shell 1, the driving gear 82 is installed on the output shaft of the driving motor three 81, the driven gear one 83 is installed on the roller shaft of the auxiliary roller 5, and the driven gear two 84 is installed on the roller shaft of the crushing roller 2. The driving gear 82, the driven gear two 84 and the driven gear one 83 are in transmission engagement in sequence.

[0078] As shown in Figure 1 and Figure 5 , the driving motor three 81 drives the driving gear 82 to rotate, because the driving gear 82, the driven gear two 84 and the driven gear one 83 are in transmission engagement in sequence, in turn drive the driven gear one 83 and the driven gear two 84 to rotate, realize the rotation of the auxiliary roller 5 and the crushing roller 2.

[0079] As shown in Figure 2 and Figure 3 , the auxiliary roller 5 and the crushing roller 2 are left with the discharge channel one, and the crushing roller 2 and the variable roller two 4 are left with the discharge channel two. The discharge channel one is located below and left of the discharge channel two. The side of the variable roller two 4 is also provided with a plurality of crushing teeth 21.

[0080] As shown in Figure 2 and Figure 3As shown, the concrete test block 6 is preliminarily crushed by the variable roller one 3 and the variable roller two 4, and the sizes are different. The smaller size concrete test block 6 can directly pass through the discharge channel one to enter the subsequent process, avoiding energy waste caused by excessive crushing. The larger size concrete test block 6 cannot enter the discharge channel one, and is guided to the discharge channel two along with the accumulation of the larger size concrete test block 6 and the rotation of the crushing roller 2, and is subjected to targeted secondary crushing through the extrusion and shearing action of the crushing roller 2 and the variable roller two 4, so that the particle size of the crushed concrete test block 6 is uniform.
