It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Combine the following Figure 1-Figure 6 The present invention is described in detail.

[0037] Example

[0038] Embodiment 1

[0039] like Figure 1-Figure 5 As shown, an intelligent asphalt synchronous stone sealing device with adjustable elevation angle includes a chassis 1 equipped with wheels 40. The wheels 40 are installed at the bottom of the chassis 1 to facilitate the movement of the device. A box 2 is installed on the chassis 1, and an elevation adjustment device is provided between the box 2 and the chassis 1. The elevation adjustment device is used to adjust the elevation angle of the box 2 according to the construction slope requirements to adapt to road construction with different slopes.

[0040] The box 2 is divided into a first chamber 201, a second chamber 202 and a third chamber 203 from left to right. By dividing the box 2 into three independent chambers, the spraying of asphalt and the spreading of stone can be effectively integrated in one device, and the spreading of asphalt and stone can be completed at the same time, which greatly improves the efficiency of road construction. In addition, the problem of asphalt cooling is avoided by paving asphalt and stone at the same time, further reducing the construction cost. The synchronous technology can ensure the firm combination between the binder and the stone, and improve the durability and stability of the paved surface.

[0041] In the specific implementation process, it is worth pointing out that the spraying of asphalt and the spreading of stone can work independently or simultaneously, and the staff can choose according to the actual situation.

[0042] The first chamber 201 is provided with a generator 3, an air compressor 4 and an asphalt conveying system 5. The generator 3 and the air compressor 4 provide power and air source for the device respectively, while the asphalt conveying system 5 is used to convey asphalt.

[0043] One side of the second chamber 202 extends to the bottom of the first chamber 201, and a silo 6 with a large angle tilt is provided in the second chamber 202 for gravity feeding. The silo 6 is designed as an internal hopper for gravity feeding, which is convenient and worry-free to operate, and does not require lifting for safe construction. When operating on a limited height construction surface, the operation is more focused and worry-free.

[0044] The third chamber 203 is provided with a burner 7 and an asphalt tank 8. A heating fire tube is provided inside the asphalt tank 8, and the fire tube is heated by the high-temperature flame generated by the burner 7. The heat is transferred to the asphalt in the asphalt tank 8 through the fire tube to increase the temperature. The heating part adopts an imported burner 7, which has automatic ignition and temperature control functions, high combustion efficiency and good atomization effect. An air control valve is provided outside the asphalt tank 8 to control the flow of asphalt in the pipeline, realize large and small cycles, and avoid local overheating or aging of the asphalt.

[0045] A discharge port 9 is provided on one side of the second chamber 202 extending to the bottom of the first chamber 201, on which a guide plate 10 is mounted, and a discharge port adjusting device is provided above the guide plate 10. The discharge port adjusting device is used to control the discharge of stones in the silo from the discharge port 9, thereby controlling the amount of stones spread thereafter. The discharge port adjusting device of this embodiment includes a stone spreading width adjusting component.

[0046] An asphalt spraying device is provided below the guide plate 10, and a stone spreading device is provided on one side of the guide plate 10. The asphalt conveying system 5 conveys asphalt to the asphalt spraying device to achieve uniform asphalt spraying, and the stone in the silo 6 passes through the discharge port 9, along the guide plate 10, and goes down to the stone spreading device, and then the stone is evenly spread by the stone spreading device.

[0047] The guide plate 10 separates the discharge port regulating device and the asphalt spraying device up and down, and the stone spreading device is arranged on one side of the guide plate 10, so that the stone spreading and the asphalt spraying do not affect each other and can be carried out synchronously.

[0048] The stone spreading device includes a roller 11 located on one side of the guide plate 10, both ends of the roller 11 are rotatably connected to a fixing plate 13 through a bearing, the fixing plate 13 is fixedly connected to the side wall of the box body 2, a spreading plate 12 is provided on one side of the roller 11, both ends of the spreading plate 12 are respectively fixedly connected to two fixing plates 13, one of the fixing plates 13 is installed with a first motor 31 for driving the roller 11 to rotate, and both ends of the asphalt spraying device are respectively fixedly connected to the two fixing plates 13. The fixing plates 13 are used to effectively fix the roller 11, the spreading plate 12 and the asphalt spraying device.

[0049] The first motor 31 is started to rotate the drum 11. The discharge port regulating device is then used to open the discharge port 9, so that the stones in the silo 6 pass through the discharge port 9 and fall onto the rotating drum 11 via the guide plate 10. Then the drum 11 throws the stones onto the spreading plate 12, which is used to block the stones brought by the drum 11 to achieve uniform spreading of the stones.

[0050] The elevation angle adjustment device includes upper ear plates 14 installed at the four corners of the bottom of the box body 2, and lower ear plates 15 that cooperate with the upper ear plates 14 are installed on the chassis 1. The upper ear plate 14 and the lower ear plate 15 on one side are rotatably connected through a pin shaft, so that one side of the box body 2 can rotate on the chassis 1.

[0051] A pin with a sleeve is installed on the upper ear plate 14 on the other side of the box body 2, and a first threaded rod 16 is vertically installed on the sleeve, and a limiting cylinder 17 is sleeved on the first threaded rod 16. The first threaded rod 16 is rotatably installed on the upper ear plate 14 by installing the pin with a sleeve, and the first threaded rod 16 is fixedly connected to the sleeve, and the limiting cylinder 17 limits the threaded rod 16, so that the threaded rod 16 can only move in the limiting cylinder 17. One side of the limiting cylinder 17 is rotatably connected to the matching lower ear plate 15 through a bearing, so that when the elevation angle is adjusted, the limiting cylinder 17 can rotate with the threaded rod 16.

[0052] A limiting nut 19 threadedly connected to the first threaded rod 16 is disposed above the limiting cylinder 17 , and an adjusting nut 18 threadedly connected to the first threaded rod 16 is disposed below the limiting cylinder 17 . The adjusting nut 18 abuts against the limiting cylinder 17 .

[0053] When dealing with the construction of ramps with different slopes, in order to ensure that the asphalt spraying device and the stone spreading device are parallel to the road surface, the staff can screw the adjusting nut 18 to make the first threaded rod 16 threadedly matched with the adjusting nut 18 move in the limiting tube 17, thereby changing the distance between the upper ear plate 14 and the lower ear plate 15 on the other side of the box body 2, so that the rotation angle of the upper ear plate 14 and the lower ear plate 15 on one side of the box body 2 is changed, that is, the elevation angle adjustment of the box body 2 is realized.

[0054] The downward movement distance depends on the distance between the limit nut 19 and the limit cylinder 17, and the upward movement distance depends on the distance between the limit nut 19 and the upper ear plate 14. At the same time, in order to limit the adjustment nut 18 to only rotate in place on the first threaded rod 16 and always abut against the limit cylinder 17, another nut can be installed under the adjustment nut 18 to lock the adjustment nut 18.

[0055] The discharge port adjustment device includes a stone spreading width adjustment component, which includes a first transverse plate 20 installed on the side wall of the box body 2, and a plurality of cylinders 21 equidistantly distributed along the axial direction of the drum 11 are rotatably connected to the first transverse plate 20, and a material gate 22 is rotatably connected to the output end of each cylinder 21, and a second transverse plate 23 installed on the side wall of the box body 2 is arranged below the first transverse plate 20, and a rotating shaft 24 is installed on the second transverse plate 23, and each material gate 22 is rotatably connected to the rotating shaft 24. The material gates 22 are controlled by the cylinders 21 that do not affect each other, so that the requirements of different spreading widths can be met.

[0056] By setting a plurality of cylinders 21 to control the rotation and opening and closing of a plurality of material gates 22 on the rotating shaft 24, the opening and closing size of the discharge port 9 in the width direction can be controlled, thereby controlling the subsequent stone spreading width. For example, when the width of four material gates 22 can meet the use requirements, four cylinders 21 are correspondingly started to open the corresponding four material gates 22, so that the stones in the silo 6 are lowered from the discharge port 9 of the opened four material gates 22 and fall onto the rotating drum 11, and then the drum 11 throws the stones onto the spreading plate 12, and the spreading plate 12 is used to block the stones brought by the drum 11, so as to achieve uniform spreading of the stones.

[0057] The coordination of the stone spreading device and the discharge port adjusting device not only ensures the uniformity of stone spreading, but also controls the amount of stone spread.

[0058] The asphalt delivery system 5 includes a second motor 32 installed in the first chamber 201, an asphalt pump 33 is installed at the output end of the second motor 32, a filter 34 is installed at the input end of the asphalt pump 33, a suction valve 35 is installed at the input end of the filter 34, and the suction valve 35 is connected to the third chamber 203 through a pipeline. When the second motor 32 is started, the asphalt pump 33 works, and the asphalt in the asphalt tank 8 is delivered to the filter 34 through the suction valve 35. The filter 34 filters the impurities in the asphalt to prevent the impurities in the asphalt from damaging the asphalt pump 33.

[0059] The asphalt spraying device includes a nozzle frame 36 connected to the output end of the asphalt pump 33 through a pipeline. The two ends of the nozzle frame 36 are fixedly connected to the two fixing plates 13 respectively. A plurality of nozzles 37 are installed on the nozzle frame 36. The plurality of nozzles 37 are evenly distributed along the axial direction of the drum 11. The asphalt filtered by the filter 34 enters the nozzle frame 36 through the pipeline from the output end of the asphalt pump 33, and is finally sprayed out through the nozzle 37. The opening and closing of each nozzle 37 of the spraying part is controlled by a separate air valve, and the opening and closing of the nozzle 37 is realized by the pneumatic system. The operation is flexible, and the spraying width and the amount of spraying can be adjusted arbitrarily.

[0060] A working platform 38 is provided on one side of the third chamber 203 away from the second chamber 202. The working platform 38 is installed on the chassis 1, so that an operator can stand on the working platform 38 to operate the equipment. A trailer hook 39 is provided on one side of the working platform 38 away from the third chamber 203. The setting of the trailer hook 39 facilitates the use of a trailer to tow the equipment.

[0061] A smoke exhaust pipe 41 is installed on the top of the asphalt tank 8. During the process of heating, storing and transporting asphalt, a large amount of waste gas and harmful gases will be generated due to the high temperature heating and chemical reaction of asphalt. The main function of the smoke exhaust pipe is to discharge the waste gas and harmful gases generated in the asphalt processing process to avoid their accumulation in the working area, thereby reducing the harm to the environment and human health.

[0062] Specifically, when using the intelligent asphalt synchronous stone sealing device with adjustable elevation angle, move the device to the construction position, and adjust the elevation angle of the box 2 by rotating the adjustment nut 18 according to the construction slope requirements. Start the generator 3 and the air compressor 4 to provide power and air source for the equipment. Start the second motor 32 to drive the asphalt pump 33 to extract the asphalt in the third chamber 203 and transport it to the nozzle rack 36, and spray it evenly on the road below the guide plate 10 through the nozzle 37. At the same time, start the first motor 31 to drive the drum 11 to rotate, and the stone falls from the silo 6 through the discharge port 9 onto the guide plate 10, and is spread on the road surface sprayed with asphalt through the spreading plate 12, realizing the synchronous sealing construction of asphalt and stone. By starting the cylinder 21, the corresponding material door 22 is opened to adjust the stone spreading width and spreading amount to meet different construction requirements.

[0063] Embodiment 2

[0064] Based on the first embodiment, this embodiment adds a material door opening and closing size adjustment component.

[0065] Specific as Figure 6As shown, the discharge port adjustment device also includes a material door opening and closing size adjustment component, and the material door opening and closing size adjustment component includes a crossbeam 25 rotatably connected to the rotating shaft 24. A first sleeve 26 is hinged on the crossbeam 25, and a first nut 27 is fixed inside the first sleeve 26. The first nut 27 is threadedly connected to the second threaded rod 28, and the first sleeve 26 and the second threaded rod 28 are threadedly connected by the first nut 27. The upper end of the second threaded rod 28 is rotatably connected to the second sleeve 29, and the second sleeve 29 is hinged on the first cross plate 20. The second threaded rod 28 is fixed on the first cross plate 20 through the second sleeve 29, and the second threaded rod 28 can rotate in the second sleeve 29, so the second sleeve 29 plays a role similar to a bearing.

[0066] The second sleeve 29 is hinged on the first transverse plate 20, so that when the cross beam 25 rotates around the rotating shaft 24, the second sleeve 29 rotates on the first transverse plate 20. Similarly, the first sleeve 26 is hinged on the cross beam 25. A second nut 30 is provided between the second sleeve 29 and the first sleeve 26 and is threadedly connected to the second threaded rod 28. The second nut 30 plays a role of limiting, limiting the moving distance of the first sleeve 26 on the second threaded rod 28.

[0067] The crossbeam 25 is arranged above the material door 22, and is used to limit the rotation angle of the material door 22 around the rotating shaft 24, thereby controlling the opening and closing size of the material door 22. By manually twisting the second threaded rod 28, the second threaded rod 28 rotates, driving the first nut 27 threadedly connected to the second threaded rod 28 to rotate, but because the first nut 27 is fixed on the first sleeve 26, the first sleeve 26 is hinged on the crossbeam 25, so that the first nut 27 moves vertically on the second threaded rod 28, thereby driving the first sleeve 26 to move vertically, and the first sleeve 26 drives the crossbeam 25 upward or downward, so that the rotation angle of the crossbeam 25 on the rotating shaft 24 is different, thereby adjusting the distance between the crossbeam 25 and the material door 22. When the crossbeam 25 is upward, the distance between the two becomes larger, and the opening and closing angle of the material door 22 is large, and when the crossbeam 25 is downward, the distance between the two becomes smaller, and the opening and closing angle of the material door 22 is small.

[0068] The setting of the material door opening and closing size adjustment component further meets different construction needs and adjusts the stone spreading amount.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
