Abstract
Description
Technical Field
[0001] The present application relates to the technical field of soil treatment equipment, and in particular to a road engineering pavement leveling machine. Background Art
[0002] Pavement flatness refers to the deviation value of the longitudinal convexity of the road surface. Pavement flatness is an important indicator in pavement evaluation and pavement construction acceptance, and mainly reflects the flatness of the longitudinal section profile curve of the pavement.
[0003] In order to more fully achieve this indicator, during the roadbed construction process of highway projects, workers usually need to use leveling equipment to level the paved roadbed soil surface to ensure that the road surface can have a more uniform asphalt thickness and better flatness after the asphalt is added.
[0004] Most existing leveling machines are equipped with large roller wheels to squeeze and flatten the road surface. Although they can effectively compact the road surface, it is difficult to flatten the protruding parts when facing a roadbed with a large protruding height. Even after leveling, there will be bulges, which will affect the subsequent asphalt paving work. Summary of the invention
[0005] In order to improve the road surface leveling effect, the present application provides a road surface leveling machine for highway engineering.
[0006] The present application provides a road engineering pavement leveling machine, which adopts the following technical solution: A road surface leveling machine for highway engineering comprises a vehicle body, a soil turning assembly, a vibration assembly, a plastic discharge assembly and an improver assembly; the soil turning assembly is arranged on the vehicle body and is used for turning the soil; an electric conveying rod and a processing box are arranged on the vehicle body; a feed inlet is connected to the processing box; the electric conveying rod is fixedly arranged on the vehicle body and is used for transporting the soil turned up by the soil turning assembly into the processing box; the vibration assembly is arranged on the vehicle body and is used for vibrating the processing box to separate stones in the soil; the plastic discharge assembly is arranged on the processing box and is used for discharging plastic debris in the soil; the improver assembly is arranged on the vehicle body and is used for spraying improver on the soil; a discharge inlet is connected to the processing box.
[0007] By adopting the above technical solution, when tilling the soil, the soil is turned over by the soil turning assembly, and then the turned over soil is transported to the processing box by the electric conveying rod, and then the processing box is vibrated by the vibration assembly. Due to the different weights of stones and soil, the two are gradually separated during the vibration of the processing box, and then the plastic discharge assembly is used to discharge the plastic chips in the soil, and finally the soil conditioner is sprayed into the treated soil by the conditioner assembly, and finally the mixture of soil and soil conditioner is re-scattered into the land through the discharge port. While tilling the soil, the soil conditioner is added to the soil, and the stones and plastic chips therein are removed, thereby improving the road leveling effect.
[0008] Optionally, the soil-turning assembly includes a protective cover, a soil-turning impeller, a first motor and a first electric telescopic rod; the protective cover is slidably connected to the vehicle body; the soil-turning impeller is rotatably arranged inside the protective cover; the first motor is fixedly arranged on the protective cover, and is used to drive the soil-turning impeller to rotate; the fixed end of the first electric telescopic rod is fixedly connected to the vehicle body, and the movable end of the first electric telescopic rod is fixedly connected to the protective cover.
[0009] By adopting the above technical solution, the first motor is used to drive the soil-turning impeller to achieve soil tillage. The setting of the protective cover can prevent soil splashing, so that as much turned-up soil as possible can be transported to the processing box. The first electric telescopic rod can adjust the height of the soil-turning impeller. When soil turning is not in progress, the soil-turning impeller is raised to avoid scratching against the road surface and causing damage to the equipment.
[0010] Optionally, a sieve plate is provided in the processing box, and the sieve plate is located at the bottom of the feed port; the processing box is slidably connected to the vehicle body; the vibration assembly includes a cam and a second motor; the cam is provided at the bottom of the processing box, and the cam is rotatably connected to the vehicle body; the second motor is fixedly provided on the vehicle body, and is used to drive the cam to rotate.
[0011] By adopting the above technical solution, the cam is driven to rotate by the second motor, and the processing box is repeatedly vibrated up and down driven by the cam. The soil entering the processing box is sent to the screen plate. Due to the vibration, the stones stay above the screen plate, and the smaller soil and plastic chips fall through the screen plate. The larger soil pieces and plastic also stay above the screen plate and cannot pass through, thereby separating the stones in the soil.
[0012] Optionally, a cutting assembly is provided on the box body, and the cutting assembly includes cutting blades and a third motor; the cutting blades are arranged in the processing box and are located above the screen plate; the third motor is fixedly arranged on the body, and the output shaft of the third motor is coaxially fixedly connected to the cutting blades.
[0013] By adopting the above technical solution, the stones and large pieces of soil and plastic above the sieve plate will be stratified under the action of vibration, and the large pieces of soil and plastic are located above the stones. The third motor drives the cutting blades to rotate, cutting the large pieces of soil and plastic into small pieces that can pass through the sieve plate. During the vibration of the processing box, the large pieces of soil and plastic fall from between the stones and the sieve plate to under the sieve plate, thereby cutting the large pieces of soil in the soil into small pieces, improving the quality of the soil and facilitating the subsequent processing of the plastic.
[0014] Since the third motor is fixed on the vehicle body and the processing box vibrates repeatedly relative to the vehicle body, the cutting blades move up and down relative to the processing box, so that a larger range of soil blocks and plastics can be cut, thereby improving the cutting effect of soil blocks and plastics, thereby further improving the soil treatment effect.
[0015] Optionally, an air blowing port is connected to the processing box and is located below the sieve plate; the plastic discharge assembly includes a discharge pipe, a fan and a collection box; the discharge pipe is connected to the interior of the processing box, and the connection point is located at the bottom of the sieve plate; the fan is installed at the opening of the air blowing port, and the fan is used to blow air into the interior of the processing box; the collection box is fixedly arranged on the vehicle body and is connected to the discharge pipe.
[0016] By adopting the above technical solution, the soil and plastic chips that fall to the bottom of the treatment box are separated into layers under the action of vibration, and the lighter plastic chips are located above the soil. A fan is used to blow air into the treatment box, and the plastic chips are discharged into the collection box through the discharge pipe, thereby completing the removal of the plastic chips in the soil.
[0017] Optionally, the improver assembly includes a storage box and a discharge pipe; the storage box is fixedly mounted on the vehicle body; both ends of the discharge pipe are respectively connected to the storage box and the interior of the processing box, and the connection point with the interior of the processing box is located at the bottom of the screen plate; a delivery pump is installed on the discharge pipe.
[0018] By adopting the above technical solution, the soil conditioner in the storage box is transported to the bottom of the treatment box by a delivery pump and fully mixed with the soil from which stones and plastic chips have been removed. The connection point between the discharge pipe and the treatment box is set as low as possible to prevent the soil conditioner from being blown away by the wind, thereby ensuring the amount of soil conditioner added to the soil and further improving the effect of soil treatment.
[0019] Optionally, a stirring impeller is provided inside the processing box, the stirring impeller is coaxially fixedly connected to the output shaft of the third motor, and the stirring impeller is located at the bottom of the sieve plate.
[0020] By adopting the above technical solution, the third motor is used to drive the stirring impeller to rotate, and the soil and the soil conditioner are stirred, so that the soil conditioner can be evenly mixed in the soil, thereby improving the effect of soil treatment. And because the treatment box vibrates repeatedly relative to the vehicle body, the stirring impeller moves up and down relative to the treatment box, and can stir the soil and the soil conditioner in a larger range, improve the stirring effect of the soil and the soil conditioner, and further improve the effect of soil treatment.
[0021] Optionally, a unloading assembly is provided on the processing box, and the unloading assembly includes a discharge plate, a fixed plate and a spring; the discharge plate is located at the opening of the discharge port and is hinged to the processing box; the fixed plate is arranged at the bottom of the discharge plate and is fixedly connected to the processing box; the two ends of the spring are respectively fixedly connected to the discharge plate and the fixed plate.
[0022] By adopting the above technical solution, when the soil at the bottom of the sieve plate accumulates to a certain amount, the gravity of the soil overcomes the upward elastic force of the spring, causing the discharge plate to rotate downward and open, and the mixture of the mixed soil and soil conditioner at the bottom of the treatment box is scattered back into the land. When a certain amount of soil is accumulated in the treatment box, it is discharged, avoiding the soil from being discharged from the discharge port before falling from the sieve plate, and thus not being mixed with the soil conditioner, thereby further improving the effect of soil treatment.
[0023] Optionally, a paving plate and a second electric telescopic rod are provided on the vehicle body; the paving plate is hinged to the vehicle body; the fixed end of the second electric telescopic rod is fixedly connected to the vehicle body, and the movable end of the second electric telescopic rod is slidably hinged to the paving plate.
[0024] By adopting the above technical solution, the paving plate is adjusted to rotate up and down using the second electric telescopic rod. When the soil is treated, the mixture of soil and soil conditioner that is re-spread into the land is spread flat. When the soil is not turned over, the paving plate is rotated upward to avoid scratching the road surface and causing damage to the equipment.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a vibration component and a plastic discharge component, soil conditioners are added to the soil while the soil is being tilled, and stones and plastic chips are removed from the soil, thereby improving the road surface leveling effect; 2. By setting the cutting assembly, not only can the large soil blocks in the soil be cut into small soil blocks, thus improving the quality of the soil and facilitating the subsequent treatment of the plastic, but also because the third motor is fixed on the vehicle body and the treatment box repeatedly vibrates relative to the vehicle body, the cutting blades move up and down relative to the treatment box, so that a larger range of soil blocks and plastics can be cut, thereby improving the cutting effect of soil blocks and plastics, and further improving the soil treatment effect; 3. By setting up the unloading component, a certain amount of soil is accumulated in the processing box before being discharged, so as to avoid the soil being discharged from the discharge port before falling from the screen plate, so as not to be mixed with the soil conditioner, thereby further improving the effect of soil treatment.

DETAILED DESCRIPTION
[0028] The following is combined with Figure 1-4 This application is described in further detail.
[0029] The present application embodiment discloses a road surface leveling machine for highway engineering.

The vehicle body 1 is an agricultural vehicle carrying a driving part.
[0030] Reference Figure 1 and Figure 2The tilling assembly 2 is arranged in front of the vehicle body 1 and is used to till the soil. The tilling assembly 2 includes a protective cover 21, a tilling impeller 22, a first motor 23 and a first electric telescopic rod 24. The protective cover 21 is slidably connected to the front end of the vehicle body 1, and the sliding axis is vertically arranged. There are three groups of tilling impellers 22, and the tilling impellers 22 are rotatably arranged inside the protective cover 21, and the rotation axis is horizontally arranged. The first motor 23 is fixedly arranged on the protective cover 21, and the output shaft of the first motor 23 is coaxially fixedly connected to the tilling impeller 22. The first electric telescopic rod 24 is vertically arranged at the front end of the vehicle body 1, the fixed end of the first electric telescopic rod 24 is fixedly connected to the vehicle body 1, and the movable end of the first electric telescopic rod 24 is fixedly connected to the top of the protective cover 21.
[0031] When tilling the soil, the first motor 23 drives the tilling impeller 22 to rotate to till the soil, and the protective cover 21 is used to prevent soil splashing. Since the height of the tilling impeller 22 is lower than the bottom of the wheel when working, the height of the tilling impeller 22 can be adjusted by the first electric telescopic rod 24, so that when not tilling the soil, the tilling impeller 22 is raised to avoid scratching the road surface and causing damage.
[0032] Reference Figure 1 and Figure 2 The vehicle body 1 is provided with a processing box 12 and an electric conveying rod 11. A feed port 121 is connected and opened on the side wall of the processing box 12. Three groups of electric conveying rods 11 are provided, and they correspond to the soil turning impellers 22 one by one. The electric conveying rods 11 are located between the processing box 12 and the soil turning impellers 22. The electric conveying rods 11 are fixedly connected to the vehicle body 1. The electric conveying rods 11 are spiral auger conveying rods driven by a motor. The electric conveying rods 11 are used to transport the soil turned up by the soil turning impellers 22 from the feed port 121 to the processing box 12.
[0033] Reference Figure 2 and Figure 3 The processing box 12 has a sieve plate 123 fixedly disposed horizontally inside, and the sieve plate 123 is located at the bottom of the feed port 121. The processing box 12 is slidably connected to the vehicle body 1 through a slide groove and a slider, and the sliding axis is vertically disposed.
[0034] Reference Figure 2 and Figure 3 The vibration assembly 3 is provided with two groups, each group includes two cams 31 and a second motor 32. The cam 31 is arranged at the bottom of the processing box 12, and the cam 31 is rotatably connected with the vehicle body 1, and the rotation axis is arranged horizontally. The second motor 32 is fixedly arranged on the vehicle body 1, and the output shaft of the second motor 32 is coaxially fixedly connected with the corresponding two cams 31.
[0035] When tilling the soil, the electric conveying rod 11 conveys the soil turned up by the soil turning impeller 22 to the top of the sieve plate 123 in the processing box 12. At this time, the second motor 32 drives the cam 31 to rotate, so that the processing box 12 is in a state of reciprocating vibration up and down, and the stones entering the soil inside the processing box 12 stay on the sieve plate 123, and the smaller soil and plastic chips fall to the bottom of the processing box 12 through the sieve plate 123, and the larger soil blocks and plastics also stay on the sieve plate 123 and cannot pass through.
[0036] Reference Figure 2 and Figure 3 The box body is provided with a cutting assembly 6, which includes a cutting blade 61 and a third motor 62. The cutting blade 61 is horizontally arranged in the processing box 12 and is located above the sieve plate 123. The third motor 62 is fixedly arranged on the top of the vehicle body 1, and the output shaft of the third motor 62 is coaxially fixedly connected with the cutting blade 61.
[0037] Since the processing box 12 is always in a vibrating state, the stones above the screen plate 123 and the large soil blocks and plastics are layered. Since the stones are heavy, the large soil blocks and plastics are located above the stones. At this time, the third motor 62 drives the cutting blades 61 to rotate to cut the soil blocks and plastics, and cut the large soil blocks and plastics into small pieces, which fall from between the stones and the screen plate 123 to below the screen plate 123 during the vibration of the processing box 12. Since the third motor 62 is fixed to the vehicle body 1, and the processing box 12 repeatedly vibrates relative to the vehicle body 1, the cutting blades 61 move up and down relative to the processing box 12, so that a larger range of soil blocks and plastics can be cut, thereby improving the cutting effect of soil blocks and plastics.
[0038] In some other embodiments, the processing box 12 is connected to a stone discharge port, and the stone discharge port is located at the top of the sieve plate 123. A stone discharge door is hingedly provided at the stone discharge port opening, and the operator can regularly clean out the stones on the sieve plate 123 through the stone discharge door.
[0039] Reference Figure 3 The processing box 12 is provided with an air blowing port 124 , which is connected to the inside of the processing box 12 , and the connecting point is located at the bottom of the sieve plate 123 .
[0040] The plastic discharge assembly 4 includes a discharge pipe 41, a fan 42 and a collection box 43. The discharge pipe 41 and the air blowing port 124 are arranged opposite to each other and are connected to the inside of the processing box 12. The discharge pipe 41 is connected to the inside of the processing box 12 at the bottom of the sieve plate 123. The discharge pipe 41 is a hose. The fan 42 is located at the opening of the air blowing port 124 and is fixedly connected to the processing box 12. The fan 42 is used to blow air into the processing box 12. The collection box 43 is fixedly arranged on the vehicle body 1 and is connected to one end of the discharge pipe 41 away from the processing box 12.
[0041] The soil and plastic chips that fall to the bottom of the processing box 12 are vibrated and layered in the processing box 12, and the lighter plastic chips are located above the soil. At this time, the fan 42 blows air into the processing box 12 to discharge the plastic chips into the collection box 43 through the discharge pipe 41.
[0042] Reference Figure 2 The improver assembly 5 includes a storage box 51 and a discharge pipe 52. The storage box 51 is fixedly arranged on the vehicle body 1, and the soil improver is placed in the storage box 51. The two ends of the discharge pipe 52 are respectively connected with the storage box 51 and the inside of the processing box 12, and the connection with the inside of the processing box 12 is located at the bottom of the blowing port 124. The discharge pipe 52 adopts a hose. A delivery pump 521 is installed on the discharge pipe 52, and the delivery pump 521 is fixedly connected to the bottom of the storage box 51.
[0043] When treating the soil, the soil conditioner in the storage box 51 is transported to the processing box 12 by the delivery pump 521 and is fully mixed with the soil from which the stones and plastic chips have been removed.
[0044] Reference Figure 3 and Figure 4 A stirring impeller 125 is provided in the processing box 12 . The stirring impeller 125 is located at the bottom of the processing box 12 and is coaxially fixedly connected to the output shaft of the third motor 62 .
[0045] The third motor 62 drives the cutting blades 61 to rotate and also drives the stirring impeller 125 to rotate, stirring the soil and the soil conditioner so that the two are fully mixed. The processing box 12 vibrates repeatedly relative to the vehicle body 1, so that the stirring impeller 125 moves up and down relative to the processing box 12, and can stir the soil and the soil conditioner in a larger range, thereby improving the stirring effect of the soil and the soil conditioner.
[0046] Reference Figure 2 and Figure 4 , a discharge port 122 is connected to the bottom of the processing box 12. A discharge assembly 7 is provided on the processing box 12, and the discharge assembly 7 includes a discharge plate 71, a fixed plate 72 and a spring 73. The discharge plate 71 is located at the opening of the discharge port 122 and is hinged to the processing box 12. The fixed plate 72 is arranged at the bottom of the discharge plate 71 and is fixedly connected to the processing box 12. Both ends of the spring 73 are fixedly connected to the discharge plate 71 and the fixed plate 72 respectively.
[0047] When the soil at the bottom of the screen plate 123 accumulates to a certain amount, the gravity of the soil overcomes the upward elastic force of the spring 73, so that the discharge plate 71 rotates downward and opens, and the mixed soil and soil conditioner mixture at the bottom of the processing box 12 is spread back into the land.
[0048] Reference Figure 1 and Figure 2The vehicle body 1 is provided with a paving plate 13 and a second electric telescopic rod 14. The paving plate 13 is hinged to the vehicle body 1, and the hinge axis is arranged horizontally. The second electric telescopic rod 14 is arranged vertically on the vehicle body 1, the fixed end of the second electric telescopic rod 14 is fixedly connected to the vehicle body 1, and a slider is hinged at the movable end of the second electric telescopic rod 14, and the slider is slidably connected to the paving plate 13.
[0049] The second electric telescopic rod 14 is used to adjust the paving plate 13 to rotate up and down, and when the soil is treated, the mixture of the soil and the soil conditioner that is re-spread into the land is paved.
[0050] The implementation principle of a road engineering pavement leveling machine in the present application embodiment is as follows: When tilling the soil, the first motor 23 drives the tilling impeller 22 to rotate to till the soil. At the same time, the electric conveying rod 11 conveys the soil turned up by the tilling impeller 22 to the top of the sieve plate 123 in the processing box 12.
[0051] The second motor 32 drives the cam 31 to rotate, so that the processing box 12 is in a state of reciprocating vibration up and down. The stones that enter the soil inside the processing box 12 stay on the screen plate 123, and the smaller soil and plastic chips fall through the screen plate 123. The larger soil pieces and plastic also stay on the screen plate 123 and cannot pass through.
[0052] Since the processing box 12 is always in a vibrating state, the stones above the sieve plate 123 and the large pieces of soil and plastic are layered. Since the stones are heavy, the large pieces of soil and plastic are located above the stones. At this time, the third motor 62 drives the cutting blades 61 to rotate to cut the soil and plastic, cutting the large pieces of soil and plastic into small pieces, which fall from between the stones and the sieve plate 123 to below the sieve plate 123 during the vibration of the processing box 12.
[0053] The soil and plastic chips that fall to the bottom of the processing box 12 are vibrated and layered in the processing box 12, and the lighter plastic chips are located above the soil. At this time, the fan 42 blows air into the processing box 12 to discharge the plastic chips into the collection box 43 through the discharge pipe 41.
[0054] The soil conditioner in the storage box 51 is transported to the processing box 12 through the delivery pump 521, and the third motor 62 drives the stirring impeller 125 to rotate to stir the soil and the soil conditioner so that the soil and the soil conditioner are fully mixed.
[0055] When the soil at the bottom of the screen plate 123 accumulates to a certain amount, the gravity of the soil overcomes the upward elastic force of the spring 73, so that the discharge plate 71 rotates downward and opens, and the mixed soil and soil conditioner mixture at the bottom of the processing box 12 is spread back into the land.
[0056] The second electric telescopic rod 14 is used to adjust the paving plate 13 to rotate up and down, so as to level the mixture of the soil and the soil conditioner to be spread back into the land.
[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
