[0023] The present invention provides a stone washing and mud removing device for subgrade and pavement construction of highway engineering. Refer to Figure 1-3 , which includes: a mud removing main machine 100, a driving motor 200, a storage box 300 and a pretreatment box 400. The driving motor 200 is installed on the outer surface of the left end of the mud removing main machine 100, and the output end of the driving motor 200 is connected to the conveying belt 110 inside the mud removing main machine 100. The storage box 300 is arranged on the right side of the mud removing main machine 100, and the pretreatment box 400 is installed on the top of the left end of the mud removing main machine 100. A feeding hopper 410 is embedded in the top of the pretreatment box 400. A wiping roller 420 is installed on the left inner wall of the pretreatment box 400, and the right inner wall is pivotally connected to a contact plate 430 through a connecting shaft 450 and is pivotally connected to the lower surface of the contact plate 430 through an elastic pressing rod 440. There are two wiping rollers 420, which are vertically distributed on the left inner wall of the pretreatment box 400. There are two elastic pressing rods 440, which obliquely support the contact plate 430, so that the gravel contacts the wiping roller 420 and then buffers and falls onto the conveying belt 110.

[0024] The output end of the driving motor 200 drives the conveying belt 110 inside the mud removing main machine 100 to transport the gravel. The storage box 300 is arranged at the right end of the mud removing main machine 100 to store the washed gravel. A wiping roller 420 is installed on the left inner wall of the pretreatment box 400 to initially wipe the surface of the gravel. The upper end of the contact plate 430 inside the pretreatment box 400 is pivotally connected to the right inner wall of the pretreatment box 400 through the provided connecting shaft 450. An elastic pressing rod 440 is arranged inside the right side of the pretreatment box 400 and is pivotally connected. The upper end of the elastic pressing rod 440 is pivotally connected to the middle of the lower surface of the contact plate 430. There are two wiping rollers 420, and they are vertically distributed on the left inner wall of the pretreatment box 400. There are also two elastic pressing rods 440, both of which are connected to the lower surface of the contact plate 430. The contact plate 430 is obliquely supported inside the pretreatment box 400 by the two elastic pressing rods 440. When the gravel is discharged from the feeding hopper 410 into the pretreatment box 400 and contacts the contact plate 430, the elastic pressing rod 440 elastically supports the contact plate 430, so that the contact plate 430 ejects the gravel, improving the contact effect between the gravel and the wiping roller 420, thereby initially removing the dirt on the surface of the gravel. And under the elastic buffer of the contact plate 430, the gravel slowly falls onto the surface of the conveying belt 110, avoiding damage to the conveying belt 110 caused by a large falling gravity.

[0025] In one embodiment, refer to Figure 4, in the middle of the mud removal main machine 100, there is a brush roller box 120. Inside the brush roller box 120, there is a blower 121. The blower 121 is connected to a roller 123 through a conduction hose 122. On the surface of the roller 123, there are brush bristles 124 and air jet holes 125. The air jet holes 125 penetrate through the inside of the roller 123. There are four groups of brush bristles 124 and air jet holes 125 respectively, which are distributed around the surface of the roller 123 at intervals.

[0026] The wind energy generated inside the blower 121 is conducted to the inside of the roller 123 installed below the brush roller box 120 through the conduction hose 122. The jetting ability is generated through the four groups of air jet holes 125 to jet the dirt in the gaps between the gravels, improving the effect of the dirt falling off from the gaps between the gravels. Combined with the four groups of brush bristles 124 to clean the dirt on the surface of the gravels, the effect of cleaning the dirt in the gaps between the gravels is improved.

[0027] In an embodiment, both ends of the roller 123 are connected to a sliding block 127 through a hinge connecting plate 126. Inside the brush roller box 120, there is a spring 149 guide rod 128. The spring 149 guide rod 128 is in clearance fit and penetrates through the inside of the sliding block 127. There are four hinge connecting plates 126, sliding blocks 127 and spring 149 guide rods 128 respectively, and they are symmetrically distributed in two groups at both ends of the roller 123.

[0028] The spring 149 guide rod 128 is in clearance fit and penetrates through the inside of the sliding block 127 to apply elastic sliding ability to the sliding block 127. Through the two groups of spring 149 guide rods 128, reverse elastic sliding ability is applied to the sliding block 127, so that the two groups of hinge connecting plates 126 have a linkage reaction. When the gravel contacts the roller 123, the roller 123 automatically makes a vertical elastic adjustment to ensure that the brush bristles 124 on the surface of the roller 123 can effectively contact the surface of the gravel for cleaning, and at the same time avoid the gravel causing collision damage to the roller 123.

[0029] In an embodiment, refer to Figure 5-8 , inside the right end of the mud removal main machine 100, there is a cleaning box 140. An elevating box 141 is installed inside the cleaning box 140.

[0030] In the middle of the bottom of the lifting box 141, a vibration guide plate 142 is embedded. In the middle of the interior of the cleaning box 140, an ultrasonic generator 143 is installed. The ultrasonic generator 143 is separated from the bottom of the lifting box 141 by a partition plate 145 provided at the lower end inside the cleaning box 140. At the upper end of the ultrasonic generator 143, a conductor 144 is provided. The conductor 144 passes through the middle inside of the partition plate 145. And a sealing ring 146 is also provided between the conductor 144 and the partition plate 145. The bottom of the conductor 144 is embedded in the bottom of the vibration guide plate 142. Above the left end of the partition plate 145, a spring 149 is provided to make vibration damping contact with the bottom on the left side of the lifting box 141.

[0031] In an embodiment, lifting mechanisms 150 are provided on both sides of the lifting box 141. The lifting mechanism 150 includes a lifting rod 151. The lifting rod 151 contacts the top inside the outer frame 130 on the outer surface of the sludge removal main machine 100. Inside the outer frame 130, a motor 152, a worm 153, a lifting slider 154 and a guide post 155 are provided. The output end of the motor 152 drives the worm 153 to rotate. The outer side of the worm 153 passes through the lifting slider 154. The guide posts 155 are installed on both sides of the worm 153. Vertically at the rear side of the lifting slider 154, a push rod 156 is provided. The top of the push rod 156 is fixed to the bottom surface on the outer side of the lifting rod 151. The bottom surface on the outer side of the right lifting rod 151 on the right side of the lifting box 141 is fixed to the top of the telescopic guide rod 157. The telescopic guide rod 157 is fixedly installed on the outer side of the sludge removal main machine 100.

[0032] On the left side of the upper end of the lifting box 141, a left lifting rod 151 is installed. And the outer side of the left lifting rod 151 contacts the top of the outer frame 130 installed on the outer surface of the sludge removal main machine 100. At the lower end inside the outer frame 130, a motor 152 is provided. And the output end of the motor 152 drives the worm 153 to rotate. The outer side of the worm 153 passes through the lifting slider 154 and drives the lifting slider 154 to lift and slide. The lifting slider 154 vertically slides in a guiding manner through the two guide posts 155 inside the outer frame 130. Vertically at the rear side of the lifting slider 154, a push rod 156 is provided. And the top of the push rod 156 is fixed to the bottom surface on the outer side of the left lifting rod 151. On the right side of the lifting box 141, a right lifting rod 151 is also provided. And the bottom surface on the outer side of the right lifting rod 151 is fixed to the top of the telescopic guide rod 157. The telescopic guide rod 157 is fixedly installed on the outer side of the sludge removal main machine 100. The left lifting rod 151 and the right lifting rod 151 have the same shape and structure and are symmetrically installed on the left and right sides of the lifting box 141. By the rotation of the worm 153 on the left side to drive the lifting slider 154 to lift, while the push rod 156 drives the left lifting rod 151 to lift and cooperates with the telescopic guide rod 157 at the lower end of the right lifting rod 151 for telescopic guiding, ensuring that the whole lifting box 141 can stably and vertically lift and lower inside the cleaning box 140 to move the cleaned gravel out of the cleaning box 140.

[0033] In one embodiment, filters 147 are provided at the front, rear, left side, and bottom of the lifting box 141. The bottom filter 147 is inclined with the left side higher than the right side. A rotatable opening and closing door 148 is provided on the right side of the lifting box 141.

[0034] When the lifting box 141 ascends, the gravel is separated from the cleaned sewage through the four filters 147, preventing the dirt in the sewage from adhering to the surface of the gravel again. The upper end of the opening and closing door 148 on the right side of the lifting box 141 rotates downward to form an inclined guiding state, and all the cleaned gravel is discharged into the storage box 300 for storage.

[0035] The specific usage method is as follows: Put the gravel into the pretreatment box 400 from the feed hopper 410. The gravel comes into contact with both the wiping roller 420 and the contact plate 430. The elastic extrusion rod 440 elastically supports the contact plate 430, enabling the contact plate 430 to eject the gravel, improving the contact effect between the gravel and the wiping roller 420, thereby initially removing the dirt on the surface of the gravel. And under the elastic buffering of the contact plate 430, the gravel slowly falls onto the surface of the conveyor belt 110, preventing damage to the conveyor belt 110 caused by a large falling gravity. The gravel falls onto the conveyor belt 110 for transmission and is transmitted to contact the roller 123 below the brush box 120. When contacting, the two groups of springs 149 and guide rods 128 apply reverse elastic sliding ability to the sliding block 127, causing the two groups of hinged connecting plates 126 to move in conjunction. When the gravel contacts the roller 123, the roller 123 automatically makes a vertical elastic adjustment to ensure that the brush 124 on the surface of the roller 123 can effectively contact the surface of the gravel for cleaning and prevent the gravel from colliding and damaging the roller 123. At the same time, the blower 121 operates, and the wind energy generated inside the blower 121 is conducted to the inside of the roller 123 through the two conduction hoses 122. The four groups of air injection holes 125 generate an injection ability to eject the dirt in the gaps between the gravel, improving the effect of the dirt falling off from the gaps between the gravel. Combined with the four groups of brushes 124 to clean the dirt on the surface of the gravel, the effect of cleaning the dirt in the gaps between the gravel is improved. Then the gravel is transmitted into the lifting box 141 inside the cleaning box 140. There is a cleaning liquid in the cleaning box 140. Start the ultrasonic generator 143. With the cooperation of the conductor 144 and the vibration guide plate 142, the liquid inside the cleaning box 140 generates ultrasonic waves to clean the gravel. After the cleaning is completed, start the motor 152 to drive the worm 153 to rotate, thereby driving the lifting slider 154 and the push rod 156 to push the left lifting rod 151 upward. At this time, the lifting box 141 moves upward inside the cleaning box 140. When moving upward, the gravel and the sewage are separated through the filter 147, preventing impurities in the sewage from adhering to the surface of the gravel again. Finally, the upper end of the opening and closing door 148 rotates downward to form an inclined guiding state, and all the cleaned gravel is discharged into the storage box 300 for storage.

[0036] The present invention also provides a method for a stone washing and mud removing device used in the construction of highway engineering subgrade and pavement, including the following specific steps: S1: Put gravel into the interior of the pretreatment box 400 from the feed hopper 410. The gravel comes into contact with both the wiping roller 420 and the contact plate 430. Under the elastic support of the elastic extrusion rod 440, the contact plate 430 ejects the gravel, so that the gravel comes into contact with the two wiping rollers 420, and the dirt on the surface of the gravel is preliminarily wiped off by the wiping rollers 420.

[0037] S2: The wiped gravel falls onto the surface of the conveyor belt 110. Under the rotation of the driving motor 200, the conveyor belt 110 transports the wiped gravel to the lower part of the brush box 120 to come into contact with the roller 123. At this time, the blower 121 works to generate wind energy. Under the transmission of the two conduction hoses 122, the wind energy enters the interior of the roller 123 and is finally ejected from the air injection holes 125 to act on the surface of the gravel, blowing out the dirt in the gaps of the gravel, and combining with the brush 124 on the surface of the roller 123 to clean the dirt in the gaps of the gravel.

[0038] S3: Then the gravel is output and enters the lifting box 141 inside the cleaning box 140. There is cleaning liquid in the cleaning box 140. Start the ultrasonic generator 143 to make the liquid in the cleaning box 140 generate ultrasonic waves to clean the gravel. After the cleaning is completed, start the motor 152 to drive the worm 153 to rotate, thereby driving the lifting slider 154 and the push rod 156 to push the left lifting rod 151 upward. At this time, the lifting box 141 moves upward inside the cleaning box 140. When moving upward, the gravel and the sewage are separated through the filter screen 147.

[0039] In the present invention, the elastic extrusion rod 440 provides elastic support for the contact plate 430, so that the contact plate 430 ejects the gravel, improving the contact effect between the gravel and the wiping roller 420, thereby initially removing the dirt on the surface of the gravel. And under the elastic buffering of the contact plate 430, the gravel slowly falls onto the surface of the conveyor belt 110, avoiding damage to the conveyor belt 110 caused by the large falling gravity.

[0040] In the present invention, two groups of springs 149 and guide rods 128 apply reverse elastic sliding ability to the sliding block 127, so that two groups of hinge connecting plates 126 have a linkage reaction. When the gravel comes into contact with the roller 123, the roller 123 automatically makes a vertical elastic adjustment to ensure that the brush 124 on the surface of the roller 123 can effectively contact the surface of the gravel for cleaning, and avoid collision damage to the roller 123 caused by the gravel.

[0041] In the present invention, the blower 121 operates, and the wind energy generated inside the blower 121 is conducted to the inside of the roller 123 through two conduction hoses 122. The jet holes 125 in four groups generate jetting ability to jet the dirt in the gravel gaps, improving the effect of the dirt falling off from the gravel gaps. In combination with the four groups of brushes 124, the dirt on the surface of the gravel is cleaned, improving the effect of cleaning the dirt in the gravel gaps.

[0042] In the present invention, the ultrasonic generator 143 is started. Under the cooperation of the conductor 144 and the vibration guide plate 142, ultrasonic waves are generated in the liquid inside the cleaning tank 140 to clean the gravel. After the cleaning is completed, the motor 152 is started to drive the worm 153 to rotate, thereby driving the lifting slider 154 and the push rod 156 to push the left lifting rod 151 upward. At this time, the lifting box 141 moves upward inside the cleaning tank 140. When moving upward, the gravel and sewage are separated through the filter screen 147, preventing the impurities in the sewage from adhering to the surface of the gravel again.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
