Description

Technical Field

[0001] The present invention belongs to the technical field of road cleaning equipment, and in particular relates to a highway roadside anti-scattering device and its application. Background Art

[0002] The speed on highways is generally 80-120 km / h. When vehicles are traveling at high speeds, a clean road surface is very important. Due to the large number and variety of vehicles passing on highways, there are often scattered objects such as stones, waste tires, and cardboard boxes on the highways. These scattered objects can be fatal to passing vehicles. Therefore, many devices for cleaning scattered objects on highways have emerged in the prior art. For example, Patent Document 1 discloses a solar-powered road cleaning robot, which is slidably mounted on a guardrail and can move on the guardrail through a walking unit. The robot is also provided with a cleaning unit, which is normally retracted inside the robot and unfolded when cleaning is required. The robot first piles up road debris with a brush and then sucks up the road debris through a suction port. Although this road cleaning device can clean up scattered debris on the roadside to a certain extent, it cannot clean up scattered debris in the middle of the road. Moreover, since the robot slides on the guardrail, its driving speed is relatively slow, and the speed of cleaning scattered debris is not fast. Moreover, since the debris is piled up with a brush and then sucked up with a suction port, its processing speed is also slow. The robot can only clean scattered debris on the roadside of a highway. Another example is patent document 2, which discloses an unmanned cleaning system for cleaning on highways. The unmanned cleaning system includes an unmanned cleaning device and an unmanned guarding device. Cleaning is performed by the cooperation of the two devices. The unmanned guarding device is located behind the unmanned cleaning device to prevent people or vehicles behind the unmanned guard vehicle from overtaking the unmanned guarding device and affecting the cleaning process, thereby ensuring the safety of the cleaning process. Although it can ensure the safety of cleaning, since the speed of cars on the highway is very fast, the unmanned guarding device also hinders the normal driving of cars on the highway to a certain extent. On the speeding road, it is inevitable that some vehicles will collide with the unmanned guard vehicle behind due to factors such as untimely braking, which increases the safety of vehicles driving on the highway.

[0004] [Patent document 2]CN108589599A.

[0005] In the prior art, for the scattered debris on the side of the highway, there are either collection devices that are simply designed to slide at the roadside fence and then collect the scattered debris, or the collection of scattered debris on the highway is performed at a relatively low speed. There is no highway roadside anti-scattering device that can adapt to the high-speed vehicles on the highway to collect scattered debris, nor is there a highway roadside anti-scattering device that can cross the highway and collect scattered debris on each lane. The highway roadside anti-scattering device provided by the present invention can collect scattered debris on each lane of the highway at a certain speed, and only requires one vehicle. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing anti-scattering devices on the side of highways, the present invention provides a technical solution, a roadside anti-scattering device for highways, including a collection vehicle, the collection vehicle including a vehicle body and wheels, a scattered object collection head is provided at the lower end of the vehicle body, the scattered object collection head includes a frame and a plurality of adaptive telescopic rods slidably arranged in the frame, a plurality of inflatable cylinders are provided at positions corresponding to the adaptive telescopic rods at the rear end of the frame, an elastic membrane is fixedly provided at the rear end of the frame, a scattered object collection structure is provided in the vehicle body, the scattered object collection structure includes a horizontal buffer section, an arc buffer section and a vertical adjustment buffer section, and a plurality of buffer cylinders are provided in each buffer section When the collection vehicle is traveling at a normal speed, the scattered objects hit the adaptive telescopic rod in the scattered object collecting head. The adaptive telescopic rod slides to adapt to the shape of the scattered objects, and the sliding adaptive telescopic rod extends into the inflatable cylinder, thereby causing the elastic membrane at the rear of the scattered object collecting head to expand. At the same time, the scattered object collecting head moves backward and enters the horizontal buffer section, arc buffer section and vertical adjustment buffer section of the scattered object collecting structure. After the scattered object collecting structure absorbs the impact of the scattered objects, the elastic membrane recovers and the adaptive telescopic rod automatically resets, thereby causing the scattered objects in the scattered object collecting head to fall out and fall into the receiving box at the lower end of the scattered object collecting structure, thereby completing the collection of the scattered objects.

[0007] Preferably, the horizontal buffer section includes a cylindrical bracket, a material drop port, a first material receiving box and several buffer cylinders evenly arranged on the cylindrical bracket in a circumferential direction. The first material receiving box is located below the cylindrical bracket, and the material drop port is located at the lower end of the cylindrical bracket opposite to the first material receiving box, so as to facilitate the scattered objects to fall into the first material receiving box after the telescopic rod pushes the scattered objects out of the frame.

[0008] Preferably, the buffer cylinder includes a cylinder barrel, a piston rod and a guide ball fixedly arranged on the inner side of the cylindrical bracket. One end of the piston rod is slidably arranged in the cylinder barrel, and the other end is rotatably provided with a guide ball. The outer side of the frame is provided with a positioning groove that can cooperate with the guide ball.

[0009] Preferably, the vertical adjustment buffer section has the same structure as the horizontal buffer section, and the arc-shaped buffer section has the same structure as the horizontal buffer section except that the overall structure of the cylindrical bracket is arc-shaped.

[0010] Preferably, the arc-shaped buffer segment is composed of several arc-shaped main segments and arc-shaped inflatable segments. The arc-shaped inflatable segment is deformed due to internal inflation or deflation. When all the arc-shaped inflatable segments are filled with air, the arc length of the arc-shaped buffer segment is Π / 4. When all the arc-shaped inflatable segments are empty and in a contracted state, the arc length of the arc-shaped buffer segment formed by all the arc-shaped main segments is Π / 8.

[0011] Preferably, the cylinder barrel of the buffer cylinder of the horizontal buffer section is connected to the arc-shaped inflation section through an air pipe. When the scattered object collection head passes through the horizontal buffer section and squeezes the piston rod to retract the cylinder barrel, the gas flows into the arc-shaped inflation section through the air pipe. When all the buffer cylinders are contracted, all the arc-shaped inflation sections in the arc-shaped buffer section are filled with gas, so that the arc length of the arc-shaped buffer section is Π / 4.

[0012] The lifting of the lifting mechanism is controlled by the lifting mechanism, and the lifting mechanism is controlled by the lifting mechanism. The lifting mechanism is controlled by the lifting mechanism, and the lifting mechanism is controlled by the lifting mechanism.

[0013] Preferably, when scattered objects fall from the vertical adjustment buffer section onto the material receiving box body, the impact force of the scattered objects will cause the cylinder in the scissor mechanism to contract, thereby pressing the gas into the rodless cavity of the buffer cylinder of the arc buffer section and the vertical adjustment buffer section, so that the buffer cylinder is reset; at the same time, the falling scattered object collecting head causes the vertical adjustment buffer section to tilt to the right when passing through the arc buffer section, and at the same time, the scattered object collecting head reaches the initial position after passing through the horizontal buffer section, and the gravity of the vertical adjustment buffer section will slowly reset the buffer cylinder in the horizontal buffer section, so that the highway side anti-scattering device can enter the next scattered object cleaning work.

[0014] An application of a highway roadside anti-scattering device, the application comprising the following steps:

[0015] A. Drive the collection vehicle on the emergency lane, slow lane or fast lane of the highway;

[0016] B. When the collection vehicle encounters scattered objects that need to be collected, the collection head is aimed at the scattered objects and the collection vehicle continues to travel at the original speed;

[0017] C. The inertia of the scattered objects drives the adaptive telescopic rod in the scattered object collection head to move. The adaptive telescopic rod as a whole forms a concave structure adapted to the shape of the scattered objects, so that the scattered objects are covered by the frame. At the same time, the sliding adaptive telescopic rod slides into the inflatable cylinder. The gas in the inflatable cylinder drives the elastic membrane to expand, thereby forming a scattered object collection head with a buffer structure;

[0018] D. The scattered object collection head continues to move backward and enters the scattered object collection structure. When the impact energy of the scattered object collection head is absorbed by the scattered object collection structure, it stops sliding. At the same time, the elastic membrane returns to its original shape, adapting to the telescopic rod sliding out of the inflation cylinder, thereby pushing the scattered objects out of the scattered object collection head. The scattered objects fall into the material receiving box from the material drop port, completing the collection of the scattered objects.

[0019] Preferably, it also includes step E, after the scattered object collecting head stops, the scattered objects in the scattered object collecting head slide out of the scattered object collecting head due to the influence of gravity and fall downward into the material receiving box body, or the scattered objects and the scattered object collecting head fall downward at the same time due to the influence of gravity. When they contact the material receiving box body, the scattered objects in the scattered object collecting head fall into the material receiving box body, and the scattered objects and the scattered object collecting head simultaneously squeeze the scissors-fork mechanism to move downward, and the gas in the driving cylinder of the squeezed scissors-fork mechanism fills the buffer cylinder in the vertical adjustment buffer section from top to bottom in turn, so as to ensure that the scattered object collecting head can slide out smoothly downward; when the arc-shaped buffer section tilts to the right after the scattered object collecting head passes through, the gas in the arc-shaped inflation section also fills the buffer cylinder from right to left in turn when it flows back into the horizontal buffer section. When controlling the inflation of the horizontal buffer section, wait until the scattered object collecting head enters the horizontal buffer section before proceeding. Finally, the scattered collecting head returns to its initial position.

[0020] The beneficial effects of the present invention are:

[0021] 1) The highway roadside anti-scattering device of the present invention can collect scattered objects on the highway at a certain speed. It includes a plurality of scattered object collection heads, each of which includes a frame and a plurality of adaptable telescopic rods. The adaptable telescopic rods can telescopically slide within the frame. When the device is traveling at a certain speed, the scattered object collection heads are aligned with the scattered objects. The scattered objects impact the adaptable telescopic rods due to inertia, causing the adaptable telescopic rods to deform to adapt to the shape of the scattered objects. Thus, scattered objects of various shapes can be well installed in the scattered object collection heads. The collection heads are suitable for collecting various scattered objects or those with complex shapes.

[0022] 2) The scattered object collection head of the present invention is provided with a plurality of inflatable cylinders corresponding to the adaptable telescopic rods on the rear side of the frame, and an elastic membrane is provided on the rear side of the inflatable cylinder. Due to the impact of the scattered objects, the adaptable telescopic rods move and slide into the inflatable cylinders. The plurality of inflatable cylinders inflate the elastic membranes, causing the elastic membranes to collide. The scattered object collection head converts the impact of the scattered objects into the sliding of the adaptable telescopic rods, and then converts it into an expansion blowing force on the elastic membrane. Finally, the excess impact force continues to slide backward with the inflated tail of the scattered object collection head, and continues to fall into the receiving box after being buffered by the collection structure of the scattering device, completing the collection of the scattering device;

[0023] 3) Furthermore, the scattering device collection structure of the present invention includes a horizontal buffer section, an arc buffer section and a vertical adjustment buffer section, and a plurality of buffer cylinders are provided in each buffer section. The buffer cylinder can trigger the elastic membrane surface when the scattered object collecting head passes by, thereby buffering it for the first time when the scattered object collecting head passes by, and then the scattered object collecting head that continues to pass squeezes the buffer cylinder to make it shrink and deform, thereby performing a second buffer. In this way, if the scattered object collecting head still has impact force, it will continue to pass through the arc buffer section for further buffering, and finally pass through the vertical adjustment buffer section for deceleration. In the vertical adjustment buffer section, since it is also necessary to overcome the influence of gravity, it can better buffer the scattered object collecting head. At the same time, a material receiving box is provided at the lower end of the horizontal buffer section, the arc buffer section and the vertical adjustment buffer section. After the impact force of the scattered objects in the scattered object collecting head is absorbed, the reset spring on each adaptive telescopic rod drives it to reset, so that the scattered objects can exit the frame of the scattered object collecting head and fall into the material receiving box, thereby completing the collection of the scattered objects;

[0024] 4) Furthermore, the arc-shaped buffer section is composed of a plurality of arc-shaped main sections and arc-shaped inflatable sections. The air outlet end of the buffer cylinder 23 of the horizontal buffer section is connected to the arc-shaped inflatable section. After all the buffer cylinders 23 of the horizontal buffer section are contracted and deformed, all the arc-shaped inflatable sections in the arc-shaped buffer section 14 are inflated, so that the vertical adjustment buffer section 15 is located in a vertical position. At the same time, the second material receiving box provided at the lower part of the vertical adjustment buffer section is driven to rise and fall by a scissor mechanism controlled by a cylinder. The outlets of the arc-shaped buffer section and the buffer cylinder in the vertical adjustment buffer section are both connected to the cylinder. As the buffer cylinder in the arc-shaped buffer section contracts, the second material receiving box rises accordingly. After passing through the arc-shaped buffer section 14, the height of the second material receiving box is located at the lower part of the vertical adjustment buffer section. The buffer cylinder in the vertical adjustment buffer section continues to drive the scissor mechanism to rise and fall, so that the material receiving box can adapt to the height of the scattered objects and prevent the scattered objects from falling and damaging the device.

[0025] 5) Furthermore, the highway roadside anti-scattering device of the present invention further comprises a lateral guiding telescopic slide rail, one end of which is slidably connected to the guardrail by a synchronous driving vehicle, and the other end is connected to the collection vehicle. The lateral guiding telescopic slide rail is a flat telescopic plate structure, which will not affect the normal driving of vehicles in the lane between the collection vehicle and the guardrail. When scattered objects need to be collected in a lane away from the guardrail, the wheels are turned to drive into the corresponding lane. When the scattered objects enter the vertical adjustment buffer section, the rising scattered object collecting head makes the collection vehicle weightless. At this moment, the collection vehicle is driven to the side of the guardrail 2, and the lateral guiding telescopic rail is contracted, which together drives the collection vehicle to quickly drive toward the guardrail. The vehicle also decelerates accordingly during driving. Finally, when the scattered objects fall and cause an impact, the collection vehicle is in a parked state, thereby ensuring the safety of the collection vehicle in collecting scattered objects.

[0026] 6) Furthermore, in order to enable the scattered object collection head loaded with scattered objects to decelerate and stop in the vertical adjustment buffer section, the vertical adjustment buffer section can be a plurality of sleeve structures, so that the vertical adjustment buffer section can adapt to the speed of the scattered object collection head and perform corresponding expansion and contraction, thereby ensuring the safe collection of scattered objects;

[0027] 7) Furthermore, the buffer cylinder of the horizontal section and the arc-shaped inflatable section of the present application are interconnected, and the buffer cylinder of the arc section, the buffer cylinder of the vertical adjustment buffer section and the driving cylinder of the scissors-fork mechanism are connected. Through the above-mentioned interconnected structure, the impact energy of the scattered objects can be well utilized, and the impact energy can be converted into a driving force for adjusting the position of the vertical adjustment buffer section and a driving force for lifting and lowering the scissors-fork mechanism. After the scattered objects stop moving, the fallen scattered objects can impact the scissors-fork mechanism, and the scissors-fork mechanism can buffer the scattered objects. The falling impact force of the scattered objects is converted into a recovery force of the buffer cylinder of the arc-shaped buffer section and the vertical adjustment buffer section, further improving the energy utilization efficiency. At the same time, the sliding scattered object collection head can make the vertical adjustment buffer section tilt to the right, drive the arc-shaped inflatable section to recover, and the recovered arc-shaped inflatable section can make the buffer cylinder of the horizontal buffer section recover. The action force of the entire device is provided by the inertia force of the scattered objects, which not only saves energy, but also enables the vehicle body to collect scattered objects at a higher speed.

[0035] The present invention is further described below with reference to the embodiments, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0036] A highway roadside anti-scattering device, such as Figure 1-4 As shown, the collecting vehicle 3 includes a vehicle body 6 and wheels 29. The lower end of the vehicle body 6 is provided with a scattered object collecting head 7. Figure 3 As shown, it includes a frame 8 and several adaptive telescopic rods 9 slidably arranged in the frame 8, and several inflatable cylinders 10 are arranged at the position corresponding to the adaptive telescopic rod 9 at the rear end of the frame 8. An elastic membrane 12 is fixedly arranged at the rear end of the frame 8. A scattered object collection structure is provided in the vehicle body 6. The scattered object collection structure includes a horizontal buffer section 13, an arc buffer section 14 and a vertical adjustment buffer section 15. Each buffer section is provided with several buffer cylinders 23. When the collection vehicle 3 is traveling at a normal speed, such as a driving speed of 60-80 km / h or even 100 km / h, the scattered objects impact the scattered object collection head 7. The adaptive telescopic rod 9 slides to adapt to the shape of the scattered objects, and the sliding adaptive telescopic rod 9 extends into the inflatable cylinder 10, thereby expanding the elastic membrane 12 at the rear of the scattered object collecting head 7. At the same time, the scattered object collecting head 7 moves backward and enters the horizontal buffer section 13, arc-shaped buffer section 14 and vertical adjustment buffer section 15 of the scattered object collecting structure. After the scattered object collecting structure absorbs the impact of the scattered objects, the elastic membrane 12 recovers and the adaptive telescopic rod 9 automatically resets, thereby causing the scattered objects in the scattered object collecting head 7 to fall out and fall into the receiving box at the lower end of the scattered object collecting structure, thereby completing the collection of the scattered objects.

[0037] Preferably, a reset spring 27 is further sleeved on the outer side of the adaptive telescopic rod 9, and the reset spring 27 can quickly reset the adaptive telescopic rod 9.

[0038] Preferably, the elastic membrane 12 is made of PVC or rubber.

[0039] Preferably, in order to allow the gas in each inflatable cylinder 10 to fully contact, avoid the elastic membrane blocking the channel of each inflatable cylinder 10, and also avoid the elastic membrane from being strongly impacted by some inflatable cylinders 10 and affecting its service life, a buffer chamber 11 is also provided between the inflatable cylinder 10 and the elastic membrane 12.

[0040] Preferably, the frame 8 is square or circular, and a plurality of adaptable telescopic rods 9 are evenly distributed in the frame 8. Preferably, the frame 8 is square, and the adaptable telescopic rods 9 are evenly arranged in 5 rows and 5 columns.

[0041] Preferably, if Figure 4-5As shown, the horizontal buffer section 13 includes a cylinder bracket 21, a material drop port 22, a first material receiving box 16 and a plurality of buffer cylinders 23 evenly arranged circumferentially on the cylinder bracket 21. The first material receiving box 16 is located below the cylinder bracket 21. The material drop port 22 is located at the lower end of the cylinder bracket 21 and is opposite to the first material receiving box 16. It is used to facilitate the scattered objects to fall into the first material receiving box 16 after the telescopic rod 9 pushes the scattered objects out of the frame 8.

[0042] Preferably, the buffer cylinder 23 includes a cylinder 24, a piston rod 25 and a guide ball 26 fixedly arranged on the inner side of the cylindrical bracket 21. One end of the piston rod 25 is slidably arranged in the cylinder 24, and the other end is rotatably provided with a guide ball 26. The outer side of the frame 8 is provided with a positioning groove 32 that can cooperate with the ball 26.

[0043] Preferably, the vertical adjustment buffer section 15 has the same structure as the horizontal buffer section 13 , and the arc-shaped buffer section 14 has the same structure as the horizontal buffer section except that the overall structure of the cylindrical bracket is arc-shaped.

[0044] Preferably, the arc-shaped buffer segment 14 is composed of several arc-shaped main segments 30 and arc-shaped inflatable segments 31. The arc-shaped inflatable segment 31 is deformed due to internal inflation or deflation. When all the arc-shaped inflatable segments 31 are filled with air, the arc length of the arc-shaped buffer segment 14 is Π / 4 (that is, the whole is 1 / 4 of a circle). When all the arc-shaped inflatable segments 31 are airless and in a contracted state, the arc length of the arc-shaped buffer segment 14 formed by all the arc-shaped main segments 30 is Π / 8 (that is, the whole is 1 / 8 of a circle).

[0045] Preferably, the cylinder barrel 24 of the buffer cylinder 23 of the horizontal buffer section 13 is connected to the arc-shaped inflation section 31 through an air pipe. When the scattered object collection head 7 passes through the horizontal buffer section 13 and squeezes the piston rod 25 to retract the cylinder barrel 24, the gas flows into the arc-shaped inflation section 31 through the air pipe. When all the buffer cylinders 23 are contracted, all the arc-shaped inflation sections 31 in the arc-shaped buffer section 14 are filled with gas, so that the arc length of the arc-shaped buffer section 14 is Π / 4.

[0046] Preferably, a second material receiving box 17 is provided at the lower end of the arc-shaped buffer section 14, and the second material receiving box 17 includes a material box base 18, a scissors-fork mechanism 19 and a material receiving box body 20. The material box base 18 is fixedly arranged in the vehicle body 6, and the lower end of the scissors-fork mechanism 19 is connected to the material box base 18, and the upper end is connected to the material receiving box body 20. The scissors-fork mechanism 19 can drive the material receiving box body 20 to rise and fall.

[0047] Preferably, the scissor mechanism 19 is driven to rise and fall by a cylinder.

[0048] Preferably, the rodless cavity of the cylinder is connected to the cylinder barrel 24 of the buffer cylinder 23 in the arc-shaped buffer section 14 and the cylinder barrel 24 of the buffer cylinder 23 in the vertical adjustment buffer section 15 through an air pipe. After the scattered object collecting head 7 slides into the arc-shaped buffer section 14, the gas in the contracted buffer cylinder 23 enters the rodless cavity of the cylinder, driving the scissors-fork mechanism 19 to rise. When the upper end of the receiving box body 20 on the scissors-fork mechanism 19 extends into the arc-shaped buffer section 14, the scattered object collecting head 7 is located above the receiving box body 20, and the scattered object collecting head 7 that continues to rise continues to squeeze the buffer cylinder 23, and the contracted buffer cylinder 23 continues to make the scissors-fork mechanism 19 rise, so that the receiving box body 20 can adapt to the movement height of the scattered object collecting head 7.

[0049] Preferably, the vertical adjustment buffer section 15 can include several retractable sleeve structures. After the buffer cylinders 23 in one sleeve structure are deformed and contracted, they can continue to drive the other sleeve structure to rise, thereby lengthening the length of the vertical adjustment buffer section 15. In this way, it can be ensured that the scattered object collection head 7 can reduce the rising speed to zero.

[0050] Preferably, the upper end of the vertical adjustment buffer section 15 is a closed structure, so that the scattered object collection head can reduce its speed to zero through physical obstruction.

[0051] Preferably, when the scattered objects fall from the vertical adjustment buffer section 15 onto the receiving box body 20, the impact force of the heavy object will cause the cylinder in the scissor mechanism 19 to contract, thereby pressing the gas into the rodless cavity of the buffer cylinder 23 of the arc-shaped buffer section 14 and the vertical adjustment buffer section 15, so that the buffer cylinder 23 is reset.

[0052] Preferably, when the scattered object collecting head 7 falls through the arc buffer section 14, the vertical adjustment buffer section 15 tilts to the right. At the same time, the scattered object collecting head reaches the initial position after passing through the horizontal buffer section 13. The gravity of the vertical adjustment buffer section 15 will slowly reset the buffer cylinder 23 in the horizontal buffer section 13, so that the highway side anti-scattering device can enter the next scattered object cleaning work.

[0053] Preferably, in order to speed up the resetting of the buffer cylinder 23 , a second resetting spring 28 may be provided on the outer end of the piston rod 25 .

[0054] Preferably, in order to control the gas flow in the trachea, a solenoid valve is provided in the trachea. Preferably, in order to sense the position of the scattered object collection head, a displacement sensor or a position sensor can be provided.

[0055] Preferably, in order to enable the collection vehicle 3 to quickly return to the side of the guardrail 2, the device also includes a lateral guide telescopic rail 4, one end of which is connected to the synchronous drive vehicle 5, and the other end is connected to the collection vehicle 3. The lateral guide telescopic rail 4 is a plate-like rail structure composed of several flat telescopic plates. Therefore, it will not hinder the normal driving of vehicles on the lane between the guardrail 2 and the collection vehicle 3.

[0056] Preferably, the retraction of the lateral guide telescopic rail 4 is achieved by providing a retraction wire structure. A wire spool is provided on the left side of the lateral guide telescopic rail 4. The wire on the wire spool passes through the inner side of the telescopic plate and then the end is connected to the rightmost telescopic plate. After the wire spool retracts, the collection vehicle 3 is retracted toward the guardrail 2, and the lateral guide telescopic rail 4 is retracted. At the same time, when the lateral guide telescopic rail retracts, the speed of the collection vehicle 3 can be gradually reduced, thereby ensuring that the speed is relatively low when retracting to the vicinity of the guardrail 2. When scattered objects fall, the collection vehicle 3 is in a stopped state, avoiding the impact of scattered objects falling on the vehicle body 6 on the vehicle's movement.

[0057] Preferably, the present invention further provides an application of a highway roadside anti-scattering device, the application comprising the following steps:

[0058] A. Drive the collection vehicle 3 to travel on the emergency lane 1-1, slow lane 1-2, or fast lane 1-3 of the highway 1;

[0059] B. When the collection vehicle 3 encounters scattered objects that need to be collected, the collection head 7 is aimed at the scattered objects and the collection vehicle 3 continues to travel at the original speed;

[0060] C. The inertia of the scattered objects drives the adaptive telescopic rod 9 in the scattered object collection head 7 to move. The adaptive telescopic rod 9 as a whole forms a concave structure adapted to the shape of the scattered objects, so that the scattered objects are covered in the frame 8. At the same time, the sliding adaptive telescopic rod 9 slides into the inflation cylinder 10. The gas in the inflation cylinder 10 drives the elastic membrane 12 to expand, thereby forming a scattered object collection head with a buffer structure;

[0061] D. The scattered object collecting head continues to move backward and enters the scattered object collecting structure. When the impact energy of the scattered object collecting head is absorbed by the scattered object collecting structure, it stops sliding. At the same time, the elastic membrane 12 returns to its original shape, adapting to the telescopic rod 9 sliding out of the inflatable cylinder 10, thereby pushing the scattered objects out of the scattered object collecting head 7, and the scattered objects fall into the material receiving box from the material drop port 22, completing the collection of the scattered objects.

[0062] Preferably, in step D, the scattered object collection head enters the horizontal buffer section 13, the arc-shaped buffer section 14 and / or the vertical adjustment buffer section 15 of the scattered object collection structure for buffering and deceleration, and the elastic membrane expanded at the rear end of the scattered object collection head 7 squeezes the buffer cylinder 23 in each buffer section in turn to decelerate. After the scattered object collection head 7 squeezes all the buffer cylinders 23 through the horizontal buffer section 13 and contracts, the gas in the squeezed buffer cylinder 23 enters all the arc-shaped inflatable sections 31 in the arc-shaped buffer section 14, so that the arc-shaped buffer section 14 is fully expanded, and then the scattered object collection head 7 continues to enter the arc-shaped buffer section 14, and the scattered object collection head 7 squeezes the buffer cylinders 23 in the arc-shaped inflatable sections 31 in the arc-shaped buffer section 14. When the cylinder 23 is punched, the gas in the squeezed buffer cylinder 23 in all the arc-shaped buffer sections 14 enters the driving cylinder of the scissor-fork mechanism 19, driving the scissor-fork mechanism to rise synchronously, and when the scissor-fork mechanism 19 rises to contact the arc-shaped buffer section 14, the scattered object collecting head 7 is just above the material receiving box body 20, and the scattered object collecting head 7 continues to slide up to squeeze the buffer cylinder 23, and the gas in the squeezed buffer cylinder 23 continues to enter the driving cylinder of the scissor-fork mechanism, driving the scissor-fork mechanism 19 to rise synchronously. After the scattered object collecting head 7 slides to the top of the vertical adjustment buffer section 15, it is blocked by the closed structure at the upper end of the vertical adjustment buffer section 15, and the speed is finally stopped.

[0063] Preferably, the step E is also included. After the scattered object collecting head 7 stops, the scattered objects in the scattered object collecting head 7 slide out of the scattered object collecting head 7 due to the influence of gravity and fall downward into the material receiving box 20, or the scattered objects and the scattered object collecting head 7 fall downward at the same time due to the influence of gravity. When they contact the material receiving box 20, the scattered objects in the scattered object collecting head 7 fall into the material receiving box 20, and the scattered objects and the scattered object collecting head 7 squeeze the scissor mechanism 19 to move downward at the same time. The gas in the driving cylinder of the squeezed scissor mechanism 19 sequentially presses The buffer cylinder 23 in the vertical adjustment buffer section 15 is filled from top to bottom, which can ensure that the scattered object collection head 7 can slide out smoothly downward; similarly, when the vertical adjustment buffer section 15 tilts to the right after the scattered object collection head 7 passes through the arc buffer section 14, the gas in the arc inflation section 31 flows back into the horizontal buffer section 13 and fills the buffer cylinder 23 in sequence from right to left. When controlling the inflation of the horizontal buffer section 13, it can wait until the scattered object collection head 7 enters the horizontal buffer section 13 before proceeding. Finally, the scattered object collection head 7 returns to its initial position.

[0064] Preferably, if the scattered objects do not fall out of the vertical adjustment buffer section 15 or the arc-shaped buffer section 14, the scattered objects are also pushed out of the frame 8 due to the recovery of the elastic membrane 12. When passing through the horizontal buffer section 13, due to the influence of gravity, they can also fall into the first receiving box 16. Preferably, the timing and sequence of the above-mentioned inflation are controlled by the solenoid valve in the inflation tube. The above-mentioned means are common knowledge in the art and do not involve the key points of the present invention, so they will not be described in detail.

[0065] Preferably, in order to ensure that the scattered objects in the scattered object collection head are discharged smoothly, an air pump can be set in the buffer chamber 11. After detecting that the scattered object collection head stops, the air pump is activated to rush in gas, and the auxiliary elastic membrane 12 drives the adaptive telescopic rod 9 to reset, ensuring that the scattered objects slide out smoothly.

[0066] Preferably, after the scattered object collecting head enters the arc-shaped buffer section 14, the driving wheel 29 turns and the lateral guide telescopic rail 4 is driven to retract. Since the scattered object collecting head is moving upward at this time, the vehicle body 6 is in a weightless state, and the power required for the vehicle body 6 will become less. The speed of the driving wheel 29 of the vehicle body 6 can be slowed down accordingly, and the vehicle body 6 can also easily move toward the side of the guardrail 2. After the vehicle body 6 reaches the side of the guardrail 2, the speed of the driving wheel 29 can be further slowed down and finally stopped. Preferably, the stopping time can be selected as the scattered objects falling into the receiving box body 20, which can further reduce the impact of the scattered objects on the vehicle body 6 on driving.

[0067] Preferably, the driving speed of the synchronous driving vehicle 5 is the same as that of the collecting vehicle 3 to ensure synchronous driving. Preferably, after the collecting vehicle 3 is located at the guardrail side, the collecting vehicle 3 can be driven to travel only by the synchronous driving vehicle 5.

[0068] Through the above arrangement, the collection vehicle can collect scattered objects in the emergency lane 1-1, the slow lane 1-2, the fast lane 1-3 and / or near the guardrail, thereby expanding the working range of the collection vehicle.

[0069] Preferably, in order to adapt to the use range of the scattered object collection head 7, the scattered object collection head 7 is slidably set in a frame, and the frame can be driven by a telescopic structure to move up and down and left and right. The specific telescopic structure can use an existing oil cylinder, piston, screw structure, etc. In order to achieve the alignment of the scattered object collection head 7 and the scattering device collection structure, a positioning mechanism can be set, such as a limit switch or a camera, etc. This is not the focus of the present invention, so it will not be repeated.

[0070] Preferably, in order to adapt to the collection of scattered objects at different speed ranges, several scattered object collection structures are arranged side by side in the vehicle body, and the lengths of the horizontal buffer section 13, the arc buffer section 14 and the vertical adjustment buffer section 15 corresponding to different scattered object collection structures are different, so that it can adapt to the speed of the vehicle and drive the scattered object collection head 7 to move horizontally to the opening of the corresponding scattered object collection structure, thereby further improving the applicability of the device.

Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
