Description

Technical Field

[0001] The invention relates to the technical field of road engineering material detection, and in particular to a device for detecting agglomerate particles of road surface recycled materials. Background Art

[0002] In road construction, in order to reduce the maintenance cost of the road surface and improve the environmental friendliness of the construction, recycling equipment and technology are often used to recycle and utilize road materials for resurfacing or overlaying of roads. Among them, a pavement recycled material agglomerate particle detection device is often used to screen and detect material agglomerates.

[0003] Based on the detection of agglomerate particles of road recycling materials, some existing technologies have been found through searching, and they are introduced one by one:

[0004] First, the Chinese patent with authorization announcement number CN204718930U discloses a device for detecting agglomerate particles of road recycled materials. The pressing block is manually lifted through a bolt ring, and then released to impact a sample of recycled material particles through the pressing block. After the impact is completed, the sample is taken out for particle size detection. According to the increase in the particle size of the sample, it is identified whether the sample is agglomerate particles in the recycled material. This detection method requires manual lifting of the pressing block, and the impact relies on the gravitational potential energy of the pressing block. Therefore, the force used to lift the pressing block is relatively large, and the manpower requirements are high. In addition, the crushing method relies on impact, which is relatively simple and needs to be improved.

[0005] Secondly, the Chinese patent with authorization announcement number CN212904396U discloses a device for detecting particles of road recycling material lumps, which screens and detects material lumps through a sieve plate, and larger material lumps are guided into a recycling box, where they are crushed and re-screened by an extrusion mechanism. The extrusion mechanism uses an extrusion roller to crush the material, and the crushing method is relatively simple and the crushing effect is poor, which affects the accuracy of the final detection result and needs to be improved.

[0006] From the above, it can be seen that the crushing of the lump material sample is one of the factors affecting the accuracy of the final test results. Based on the crushing of the lump material sample, after searching, it was found that the Chinese patent with authorization announcement number CN117380307B discloses a device and method for preparing recycled aggregates from construction residues. During crushing, the crushing action is composed of rolling, hammering and impact, and the crushing effect is better. However, it also has some shortcomings. For example, the material is input from the feed hopper and output from the discharge hopper. Therefore, the crushing must be completed on the trajectory from input to output. The center angle of the trajectory is less than 360 degrees. Therefore, in the rolling action, the support plate pulls the material to move at a relatively slow speed so that the material can receive sufficient time for hammering and impact. Therefore, the rolling effect is relatively poor. It is necessary to improve the crushing structure to improve the rolling effect without affecting the hammering and impact, thereby improving the crushing effect.

[0007] Based on the above, the present invention proposes a device for detecting agglomerate particles of road surface recycled materials. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This scheme achieves the crushing of the sample by applying extrusion, rolling and impact to the sample of the lump material. On this basis, compared with the prior art mentioned in the background technology, in this scheme, on the one hand, the crushing mechanism does not need to set up some additional feeding and discharging structures, which simplifies the structure and facilitates feeding and discharging. On the other hand, the rolling action is achieved by the rotation of the lower turntable. The feeding and discharging methods determine that the rotation speed of the lower turntable can be relatively faster, and the movement distance of the sample when being rolled can be longer, so the rolling effect is better, thereby improving the crushing effect of the sample. In addition, when rolling, the rotation speed becomes faster, and the advantage of the distance side length is that the upper pressure plate can be in contact with the sample at all positions along the circumferential direction to apply extrusion to the sample. If the upper pressure plate is squeezed at one or several positions on the sample each time, it is easy for these positions to be damaged over a long period of time, while the remaining parts are intact. In contrast, in this scheme, the upper pressure plate can apply extrusion to the sample at all positions along the circumferential direction. Therefore, the above situation will not or is unlikely to occur.

[0023] 2. This solution can automatically clean the residual samples on the upper pressure plate and the lower turntable after the crushing is completed, and after the cleaning is completed, the upper scraper rod and the lower scraper rod in the cleaning structure are retracted into the groove, that is, they do not occupy too much volume space.

DETAILED DESCRIPTION

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0035] Embodiment 1

[0036] Reference Figure 1-Figure 8 A road recycling material agglomerate particle detection device includes a frame 100, on which a crushing mechanism 200 and a detection mechanism 300 are installed. The former is used to crush the agglomerate material sample, and the latter is used to perform visual detection on the crushed sample, including particle size detection.

[0037] Reference Figure 3-Figure 5 The crushing mechanism 200 includes an outer casing 202 and an upper crushing assembly 209 and a lower crushing assembly 206 located in the outer casing 202 .

[0038] Reference Figure 5 and Figure 7 The upper crushing assembly 209 includes an upper pressure plate 2091 coaxially located in the outer cover shell 202, and a feed hole is coaxially opened on the end face of the upper pressure plate 2091. A feed pipe 210 extends from the upper hole of the feed hole. The feed pipe 210 is connected to the frame 100. A hopper 201 is provided at the upper pipe mouth of the feed pipe 210, and the lump material sample enters the feed pipe 210 through the hopper 201.

[0039] A guide column extends from the upper end surface of the upper pressure plate 2091, and a pressure bracket 2092 is slidably installed on the outside of the guide column. A limit ring is provided on the upper end of the guide column, and a spring 2093 is sleeved on the outside of the guide column. There are two springs 2093 and they are respectively located on the upper and lower sides of the pressure bracket 2092. A linear module 211 for driving the pressure bracket 2092 to move in the vertical direction is provided on the frame body 100.

[0040] The upper pressure plate 2091 is also provided with an impact component 212. Figure 8 The impact component 212 includes a top seat arranged at the upper end of the guide column, and two installation shafts are installed on the top seat in the horizontal direction. A counterweight block 2122 is eccentrically arranged on the outside of the installation shaft. The two installation shafts are powered by a gear set 2123 with a transmission ratio of one. A motor 2121 for driving any one of the installation shafts to rotate is also arranged on the top seat; when the motor 2121 cooperates with the gear set 2123 to drive the two symmetrically distributed counterweight blocks 2122 to rotate, vibration can be applied to the upper pressure plate 2091 in the vertical direction, and the vibration can be transmitted to the sample located below the upper pressure plate 2091 through the upper pressure plate 2091.

[0041] Reference Figure 5 and Figure 6 The lower crushing assembly 206 includes a lower turntable 2061 coaxially located below the upper pressure plate 2091, and a rotating shaft 2062 coaxially extends from the lower end surface of the lower turntable 2061. The rotating shaft 2062 is driven to rotate by a motor 207 arranged on the frame 100, and rotates with the lower turntable 2061.

[0042] A conical seat is coaxially arranged at the upper end of the lower turntable 2061, and the horizontal cross-sectional area of ​​the conical seat decreases from bottom to top. The maximum outer diameter of the conical seat is equal to or slightly smaller than the aperture of the feed hole.

[0043] Reference Figure 5 The outer diameter of the lower turntable 2061 is consistent with that of the upper pressure plate 2091, and a sleeve 203 is provided in the area between the outer cover shell 202 and the upper pressure plate 2091. The inner diameter of the sleeve 203 is consistent with the outer diameter of the upper pressure plate 2091. An upper bracket 204 extends from the upper end of the sleeve 203. The upper bracket 204 is driven by the linear module three 205 arranged on the frame 100. When it moves in the vertical direction, it will move with the sleeve 203, so that the inner circular surface of the sleeve 203 and the outer circular surface of the lower turntable 2061 and the upper pressure plate 2091 are in contact with or out of contact.

[0044] Furthermore, a lower spacer sleeve 208 is coaxially extended from the lower end surface of the lower turntable 2061, and the motor 207 is located in the lower spacer sleeve 208. Its significance is that after the crushing is completed, when the sample is output, the motor 207 is protected from contact with the sample.

[0045] Reference Figure 1-Figure 3 The detection mechanism 300 includes a suspension 302 and an outer frame 305 which are slidably installed on the frame 100 along the horizontal direction, and the sliding directions of the two are perpendicular to each other. The outer frame 305 is driven to move by a linear module 2 304 arranged on the frame 100, and the suspension 302 is driven to move by a linear module 1 301 arranged on the frame 100. A glass slide 306 is arranged in the outer frame 305, and two scanning elements 303 are arranged on the suspension 302, which are respectively located on the upper and lower sides of the glass slide 306. The scanning element 303 can be an existing camera technology or an existing scanner technology, etc., which will not be elaborated. When the outer frame 305 moves with the glass slide 306, the glass slide 306 can be located directly below the outer cover shell 202. Furthermore, a vibrator 307 is also arranged on the outer frame 305.

[0046] The working process of the first embodiment is specifically as follows:

[0047] Initially, the inner circumference of the envelope 203 fits with the outer circumference of the lower turntable 2061 and the upper pressing plate 2091, and the agglomerated material sample falls downward through the hopper 201 and the feed pipe 210. When falling, the sample is guided by the conical seat and finally falls onto the lower turntable 2061.

[0048] Then, the upper pressing plate 2091 is driven downward by the linear module 211 to squeeze the sample. At the same time, the lower rotating plate 2061 is driven to rotate by the motor 207. At the same time, the vibration energy generated by the operation of the impact component 212 is transmitted to the sample through the upper pressing plate 2091, which is equivalent to squeezing, rolling and impacting the sample, thereby crushing the sample.

[0049] After crushing, the envelope 203 is driven upward by the linear module 3 205, the upper pressure plate 2091 is driven upward by the linear module 4 211, and the lower turntable 2061 is driven to rotate at a high speed by the motor 1 207. Under the action of centrifugal force, the crushed sample is thrown away and falls downward onto the glass slide 306 through the area between the outer cover shell 202 and the lower spacer 208;

[0050] Finally, the vibrator 307 is used to drive the glass slide 306 to vibrate, so that the broken samples on it change from being stacked to being laid flat. Then, through the cooperation of the linear module 1 301 and the linear module 2 304, the scanning element 303 moves relative to the glass slide 306 in the plane coordinate system, thereby realizing the scanning and shooting of the sample on the glass slide 306, and uploading the picture to the existing display technology for the staff to enlarge and check.

[0051] From the above description, we can know that:

[0052] Compared with the prior art mentioned in the background technology, in this solution, on the one hand, the crushing mechanism 200 does not need to be additionally provided with some feeding and discharging structures, thereby simplifying the structure and facilitating feeding and discharging. On the other hand, the crushing is achieved by the rotation of the lower turntable 2061. The feeding and discharging method determines that the rotation speed of the lower turntable 2061 can be relatively faster, and the movement distance of the sample when being crushed can be longer, so the crushing effect is better, thereby improving the crushing effect of the sample.

[0053] Embodiment 2

[0054] During the sample crushing process, due to the complex composition of the pavement material, it is easy for residues to remain on the lower end surface of the upper pressure plate 2091 or the upper end surface of the lower turntable 2061. Therefore, it is necessary to clean the lower end surface of the upper pressure plate 2091 or the upper end surface of the lower turntable 2061. Furthermore, the pavement material includes asphalt, which is easy to stick to the upper pressure plate 2091 or the lower turntable 2061, and asphalt is relatively soft. If it is not cleaned, it is easy to serve as a buffer medium during the next sample crushing, affecting the crushing effect. Therefore, it is necessary to clean the lower end surface of the upper pressure plate 2091 or the upper end surface of the lower turntable 2061.

[0055] Reference Figure 7 The lower end surface of the upper pressure plate 2091 is radially provided with an upper groove, in which an upper scraper rod 2094 is installed. Initially, the lower end surface of the upper scraper rod 2094 is flush with the notch of the upper groove, so that the lower end surface of the upper pressure plate 2091 is a complete circular surface shape.

[0056] There are multiple guide pillars on the upper pressure plate 2091 for installing the impact component 212 and the linear module 5 2095. The output end of the linear module 5 2095 passes through the upper pressure plate 2091 and is connected to the upper scraper rod 2094. The upper scraper rod 2094 can be moved down to leave the upper groove or moved up to return to the upper groove through the linear module 5 2095.

[0057] Reference Figure 6 A lower groove is provided on the upper end surface of the lower turntable 2061, in which a lower scraper rod 2063 is installed, a guide rod 2065 is extended from the lower end surface of the lower turntable 2061, a lifting block 2064 is slidably installed on the outside of the guide rod 2065, a nut for preventing the lifting block 2064 from falling is provided at the bottom of the guide rod 2065, a spring 2066 is sleeved on the outside of the guide rod 2065, and the spring 2066 is located above the connection between the lifting block 2064 and the guide rod 2065.

[0058] A fixed seat 2067 is also provided on the lower end surface of the lower turntable 2061 , and a slide seat 2068 is installed on the fixed seat 2067 in a radially slidable manner along the lower turntable 2061 . The slide seat 2068 is located on the side of the lifting block 2064 facing the axis of the lower turntable 2061 .

[0059] The side of the slide 2068 facing the lifting block 2064 is provided with a slope 1, and the side of the lifting block 2064 facing the slide 2068 is provided with a slope 2. The slope 1 is in contact with the slope 2, and the distance between the slope 1 and the axis line of the lower turntable 2061 decreases from bottom to top along the vertical direction.

[0060] The lifting block 2064 is connected to the lower scraper rod 2063, and the lower turntable 2061 is provided with an avoidance opening for avoiding the lifting block 2064. Similarly, initially, the upper end surface of the lower scraper rod 2063 is flush with the notch of the lower groove. When the lower turntable 2061 rotates at a higher speed, under the action of centrifugal force, the slide 2068 will move away from the axis of the lower turntable 2061. Through the cooperation of inclined plane 1 and inclined plane 2, the lifting block 2064 is pushed to move upward, and the lower scraper rod 2063 is moved upward together and leaves the lower groove. After the lower turntable 2061 stops rotating or the speed slows down, the centrifugal force disappears or gradually decreases, and the spring 1 2066 releases the elastic force, thereby causing the lower scraper rod 2063 to move downward and return to the lower groove.

[0061] The working process of the second embodiment is specifically as follows:

[0062] After the sample is crushed and discharged, the upper scraper 2094 is moved downward by the linear module 5 2095, and then the upper pressure plate 2091 is driven downward by the linear module 4 211, so that the upper scraper 2094 contacts the lower turntable 2061, and the lower turntable 2061 rotates at the same time, so that the lower turntable 2061 can be cleaned. After cleaning, the upper scraper 2094 returns to the upper groove;

[0063] By rotating the lower turntable 2061 at high speed, the lower scraper rod 2063 moves up and contacts the upper pressure plate 2091. At the same time, the lower turntable 2061 rotates to complete the cleaning of the upper pressure plate 2091. After cleaning, the lower turntable 2061 continues to rotate at high speed for a preset time to centrifugally throw away the remaining sample. Finally, the lower turntable 2061 stops rotating, and the lower scraper rod 2063 returns to its original position in the lower tank, and the cleaning is completed.

[0064] In this solution, the linear module can be the existing electric telescopic rod technology, or the screw linear motion technology, both of which can be realized by the existing technology and will not be described in detail.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
