Description

Technical Field

[0001] This invention relates to the field of municipal road trench cleaning technology, specifically to a municipal road construction vehicle capable of cleaning trenches. Background Technology

[0002] The foundation trenches for municipal roads are mainly used for laying water pipes and cables. During construction, the trenches are first excavated by an excavator. In order not to damage the rock layer at the bottom of the trench, a 10-15 cm base layer is usually left for manual cleaning. During cleaning, the soil on the surface of the rock layer needs to be thrown outward. After cleaning, because the rock layer of the foundation trench is uneven, crushed stone needs to be laid to ensure the flatness and stability of the bottom layer of the foundation trench. However, since the foundation trenches on both sides of the municipal roads are too long, if they are cleaned manually, it will not only consume a lot of manpower, but also increase labor costs. At the same time, the overall efficiency of foundation trench cleaning is extremely low, which brings a lot of inconvenience to people. Therefore, it is necessary to provide a municipal road construction vehicle that can clean the foundation trench to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this invention is to provide a municipal road construction vehicle capable of cleaning foundation trenches. Through adjustment and limiting mechanisms, it can adaptively simulate manual adjustment of the excavator's digging force to ensure no damage to the rock layer during trench cleaning. Furthermore, it can effectively adjust the size of the stone frame's discharge opening by utilizing the resistance between the excavator and the protruding rocks in the trench. This allows the stone frame to effectively and in a limited manner lay crushed stone on the protruding rocks while simultaneously laying a limited amount of crushed stone on the trench. This ensures that the crushed stone laid on the protruding rocks is flush with other crushed stone areas in the trench, eliminating the need for manual hand tools for trench cleaning. This increases overall practicality and convenience, improves trench cleaning efficiency, reduces manual labor, and lowers labor costs, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a municipal road construction vehicle capable of cleaning foundation trenches, comprising a vehicle body, a stone frame disposed on the upper right side of the vehicle body, and cylinders mounted on both the front and rear sides of the vehicle body. Each cylinder is connected to a first hydraulic cylinder via a piston, and a telescopic assembly is disposed on the lower left side of the first hydraulic cylinder. A fixed cylinder is mounted on the inner side of the end of the telescopic assembly, and a rotating cylinder is movably connected to the outer side of the fixed cylinder. An outer cylinder is disposed on the outer side of the rotating cylinder, and excavators are arrayed on the outer side of the outer cylinder. A mechanism is installed between the outer cylinder and the rotating cylinder to prevent damage to the bottom rock layer of the foundation trench during excavation, thus ensuring the stability of the foundation trench. The adaptive adjustment mechanism of the problem includes a fixed plate welded to the bottom of the vehicle body, and a servo motor mounted on one side of the fixed plate. The output end of the servo motor is connected to a main shaft via a coupling. A small gear is fixed to the outer side of the right end of the main shaft, and a large gear meshes below the small gear. A first driven shaft is welded through the inner side of the large gear, and a first sprocket mechanism is keyed to the outer side of the left end of the first driven shaft. A second driven shaft is keyed to the inner side below the first sprocket mechanism, and a second sprocket mechanism is keyed to the outer sides of both the left and right sides of the second driven shaft. A bevel gear set is fixed to the outer side of the left end of the second driven shaft. A support is provided on the left side of the main shaft to collect the soil generated by the excavator during the excavation of the foundation trench. The receiving set collection mechanism has a limit plate at its lower part, and an outer shell is fixedly connected to the left side of the limit plate via a support block. An inner shell is fixed inside the outer shell. A conveying auger is welded above the bevel gear set. An oil pipe is connected through the inner side of the fixed cylinder, and the upper end of the oil pipe is connected to a second oil cylinder. A limiting mechanism is installed on the inner side and upper right side of the second oil cylinder to control the size of the stone frame's discharge port based on the protruding rocks at the bottom of the trench during excavation and cleaning, thereby ensuring that the height of the crushed stone laid on the surface of the protruding rock layer is level with the height of the crushed stone laid in other parts of the trench. The adjusting mechanism includes an array of pulling blocks fixed to the inner wall of the outer cylinder, and the... The left side of the actuating block is connected to a first telescopic sleeve rod, the left end of which is connected to a first connecting pipe, and the end of the first connecting pipe is connected to an oil cavity; the collecting mechanism includes a rotating plate fixed to the left end of the main shaft, and a connecting plate is movably hinged to the left side of the rotating plate, a slider is movably connected to the left side of the connecting plate, and a groove plate is movably connected to the front side of the slider; the limiting mechanism includes a gravity block disposed inside the second oil cylinder, and a second telescopic sleeve rod is installed above the gravity block, a second connecting pipe is connected to the upper right side of the second telescopic sleeve rod, and a limiting frame is connected to the right end of the second connecting pipe, a spring is disposed on the left side inside the limiting frame, and an adjusting block is connected to the right side of the spring.

[0005] Preferably, annular plates are arranged in an array on the outer side of the fixed cylinder, and the annular plates and the inner wall of the rotating cylinder form an annular sealing sliding structure.

[0006] Preferably, the back of the vehicle body is welded to the outer shell.

[0007] Preferably, the left and right outer sides of the rotating drum are keyed to the inner sides above the two second sprocket mechanisms.

[0008] Preferably, the slider and the limiting plate form a left-right sliding structure.

[0009] Preferably, a boss is fixed on the upper right side of the limiting plate.

[0010] Preferably, a crushing rod is fixedly installed on the outer side below the conveying auger.

[0011] Preferably, the inner wall of the second oil cylinder and the outer side of the gravity block form a lifting, sealing, and sliding structure.

[0012] Preferably, oil is provided on the inner side above the second telescopic sleeve and on the left side inside the limiting frame.

[0013] Preferably, the adjusting block and the digging head have a one-to-one correspondence. Compared with the prior art, the beneficial effects of the present invention are: 1. This invention includes an adjustment mechanism and a limiting mechanism. Utilizing the rotation of the drum and the fact that the weight of the gravity block is greater than the resistance of the excavator head to the trench cleaning and excavation, the oil squeezed by the gravity block through the oil pipe, in conjunction with the oil chamber and the first connecting pipe, extends the first telescopic sleeve. This effectively pushes the pulling block, outer cylinder, and excavator head clockwise, thereby effectively cleaning and excavating the trench soil. During the cleaning and excavation process, if the excavator head encounters protruding rocks in the trench, the resistance between the excavator head and the rock is greater than the resistance between the excavator head and the soil, and simultaneously greater than the weight of the gravity block. This causes the excavator head, outer cylinder, and pulling block, along with the first telescopic sleeve, to reverse direction, effectively squeezing the oil inside the first telescopic sleeve. This, in conjunction with the first connecting pipe, oil chamber, and oil pipe, squeezes the oil into the inner side of the second oil cylinder, which, in turn, drives the gravity block to... The second telescopic sleeve is squeezed, which effectively works with the second connecting pipe to squeeze the oil into the inner side of the limiting frame. This causes the adjusting block to extend to the right with the spring, adjusting the size of the stone frame outlet. Compared with existing technologies, this technology can not only adaptively simulate the manual adjustment of the excavator's digging force on the trench to ensure that the rock layer is not damaged during trench cleaning, but also effectively adjust the size of the stone frame outlet through the resistance between the excavator and the protruding rocks in the trench. This allows the stone frame to effectively lay crushed stone on the trench while also effectively laying a limited amount on the protruding rocks, ensuring that the crushed stone area on the protruding rocks is flush with other crushed stone areas in the trench. This also avoids the need for manual hand tools to clean and excavate the trench, thus increasing the overall practicality and convenience, improving the efficiency of trench cleaning, reducing manual labor, and lowering labor costs. 2. This invention features a collection mechanism. A connecting plate drives a slider, which, in conjunction with a limiting plate, moves left and right. This effectively moves the trench plate intermittently left and right, intermittently inserting it between two excavators. This effectively collects the soil excavated by the excavators. The intermittent rightward movement of the trench plate, along with a boss, effectively lifts the right side of the trench plate around the hinge point between the trench plate and the slider. This allows soil from the inside of the trench plate to be poured into the inner shell. A crushing rod then breaks up the poured soil. A conveying auger, in conjunction with the inner shell, transports the broken soil upwards and discharges it to the outside of the trench. Compared to existing technologies, this eliminates the need for manual tools to throw soil out of the trench, further reducing labor costs and improving the overall efficiency of trench cleaning.

A stone frame 2 is located on the upper right side of the vehicle body 1. Cylinders 3 are installed on both the front and rear sides of the vehicle body 1. Cylinders 3 are connected to a first oil cylinder 4 via pistons. A telescopic assembly 5 is located on the lower left side of the first oil cylinder 4. A fixed cylinder 6 is installed on the inner side of the end of the telescopic assembly 5. A rotating cylinder 7 is movably connected to the outer side of the fixed cylinder 6. An outer cylinder 8 is located on the outer side of the rotating cylinder 7, and excavators 9 are arranged in an array on the outer side of the outer cylinder 8. The outer cylinder 8 and the rotating cylinder... An adaptive adjustment mechanism 10 is installed between 7, which can prevent the rock layer at the bottom of the foundation trench from being damaged during the excavation process, thus affecting the stability of the foundation trench. A fixing plate 11 is welded to the bottom of the vehicle body 1, and a servo motor 12 is installed on one side of the fixing plate 11. The output end of the servo motor 12 is connected to the main shaft 13 through a coupling. A small gear 14 is fixed on the outer side near the right end of the main shaft 13, and a large gear 15 meshes below the small gear 14. A first driven shaft 16 is welded through the inner side of the large gear 15, and a first sprocket mechanism 17 is keyed to the outer side of the left end of the first driven shaft 16. A second driven shaft 18 is keyed to the inner side below the first sprocket mechanism 17, and both outer sides of the second driven shaft 18 are keyed. A second sprocket mechanism 19 is connected to the second driven shaft 18. A bevel gear set 20 is fixed to the outer side of the left end of the second driven shaft 18. A collection mechanism 21 is provided on the left side of the main shaft 13 to collect the soil generated by the excavator 9 during the trench cleaning process. A limit plate 22 is provided below the collection mechanism 21, and an outer shell 23 is fixedly connected to the left side of the limit plate 22 by a support block. An inner shell 25 is fixed inside the outer shell 23. A conveying auger 24 is welded above the bevel gear set 20. An oil pipe 26 is connected through the inner side of the fixed cylinder 6, and the upper end of the oil pipe 26 is connected to a second oil cylinder 27. The size of the discharge port of the stone frame 2 is installed on the inner side and upper right side of the second oil cylinder 27, which can be controlled by the protruding rocks at the bottom of the trench during the trench cleaning process.This is a limiting mechanism 28 that ensures the height of the crushed stone laid on the surface of the protruding rock layer is level with the height of the crushed stone laid in other parts of the trench.

[0018] Example 1 Please see Figure 1-2 , Figure 5-6 and Figure 8-10The adjusting mechanism 10 includes an array of actuating blocks 1001 fixed to the inner wall of the outer cylinder 8. A first telescopic sleeve 1002 is connected to the left side of the actuating block 1001. The left end of the first telescopic sleeve 1002 is connected to a first connecting pipe 1003, and the end of the first connecting pipe 1003 is connected to an oil cavity 1004. The left and right outer sides of the rotating cylinder 7 are keyed to the inner sides of the two second sprocket mechanisms 19. Annular plates 601 are arrayed on the outer side of the fixed cylinder 6, and the annular plates 601 and the inner wall of the rotating cylinder 7 form an annular sealing sliding structure. The limiting mechanism 28 includes a gravity block 2801 disposed inside the second oil cylinder 27, and a second telescopic sleeve 2802 is installed above the gravity block 2801. A second connecting pipe 1004 is connected to the upper right side of the second telescopic sleeve 2802. Pipe 2803, and the right end of the second connecting pipe 2803 is connected to a limiting frame 2804. A spring 2805 is provided on the left side inside the limiting frame 2804, and an adjusting block 2806 is connected to the right side of the spring 2805. The inner wall of the second oil cylinder 27 and the outer side of the gravity block 2801 form a lifting, sealing, and sliding structure. Oil is provided on the inner side above the second telescopic sleeve 2802 and on the left side inside the limiting frame 2804. The adjusting block 2806 corresponds one-to-one with the excavator head 9. First, the vehicle body 1 is manually driven into the bottom of the trench next to the municipal road. Then, the piston is driven by the cylinder 3 to squeeze the oil inside the first oil cylinder 4 downward, so that the telescopic component 5 can extend downward in a ring around the center of the second driven shaft 18. The fixed cylinder 6, rotating cylinder 7, outer cylinder 8, and excavator head 9 extend downwards simultaneously. This structure allows adjustment of the excavator head 9's depth during trench cleaning. Next, the vehicle body 1 is started, and the servo motor 12 drives the main shaft 13 to rotate, which in turn drives the pinion 14, gear 15, and first driven shaft 16 to rotate. This causes the first driven shaft 16 to drive the first sprocket mechanism 17, second driven shaft 18, and second driven shaft 18 to rotate simultaneously, subsequently rotating the rotating cylinder 7. At this point, the gravity of the gravity block 2801 exceeds the resistance of the excavator head 9 during trench cleaning. The oil squeezed by the gravity of the gravity block 2801 through the oil pipe 26, in conjunction with the oil chamber 1004 and the first connecting pipe 1003, compresses and extends the first telescopic sleeve 1002, thereby extending the rotating cylinder... 7. Under the action of rotation, the pulling block 1001, outer cylinder 8, and excavator head 9 can be effectively pushed and rotated clockwise, thereby effectively cleaning and excavating the soil in the foundation trench. In order to avoid the excavator head 9 damaging the rock layer when cleaning and excavating the foundation trench, if the excavator head 9 encounters a protruding rock in the foundation trench during the cleaning and excavation process, because the resistance between the excavator head 9 and the rock is greater than the resistance between the excavator head 9 and the soil, and is also greater than the weight of the gravity block 2801, the excavator head 9, outer cylinder 8, and pulling block 1001, together with the first telescopic sleeve 1002, generate a reverse force to deflect away the protruding part of the rock. This can effectively squeeze the oil inside the first telescopic sleeve 1002, together with the first connecting pipe 1003, oil cavity 1004, and oil pipe 26, into the inside of the second oil cylinder 27.Furthermore, the pressure of the oil can cause the gravity block 2801 to press the second telescopic sleeve 2802 upwards, thus effectively coordinating with the second connecting pipe 2803 to press the oil into the inner side of the limiting frame 2804. This allows the adjusting block 2806, in conjunction with the spring 2805, to extend to the right, adjusting the size of the stone frame 2's outlet. As the vehicle body 1 moves, the adjusting block 2806 can control the flow of crushed stone on the protruding rock layer in the upper section, ensuring it is laid precisely on the outer side of the protruding rock layer. This structure not only adaptively simulates... The manual adjustment of the excavator head 9 ensures that the rock layer is not damaged during the excavation process, and the resistance between the excavator head 9 and the protruding rocks in the trench allows the corresponding adjustment block 2806 to effectively adjust the size of the discharge port of the stone frame 2. This allows the stone frame 2 to effectively limit the amount of gravel laid on the protruding rocks in the trench while simultaneously laying gravel, ensuring that the gravel laid on the protruding rocks is flush with the rest of the trench. This also avoids the need for manual excavation using hand tools. Example 2 Please see Figure 1-4 and Figure 7 Unlike Embodiment 1, the collecting mechanism 21 includes a rotating plate 2101 fixed to the left end of the main shaft 13. A connecting plate 2102 is movably hinged to the left side of the rotating plate 2101. A slider 2103 is movably connected to the left side of the connecting plate 2102, and a grooved plate 2104 is movably connected to the front of the slider 2103. The back of the vehicle body 1 is welded to the outer shell 23. The slider 2103 and the limiting plate 22 form a left-right sliding structure. A boss 2201 is fixed to the upper right side of the limiting plate 22. A crushing rod 2401 is fixedly installed on the lower outer side of the conveying auger 24. When the main shaft 13 rotates, it can also drive the rotating plate 2101 to rotate, causing the connecting plate 2102 to drive the slider 2103 to move left and right in conjunction with the limiting plate 22, thereby effectively... The trough plate 2104 moves intermittently left and right. Due to the speed difference between the pinion 14 and the gear 15, the trough plate 2104 can intermittently insert between the two excavators 9, thus effectively receiving the soil excavated from the excavators 9. By using the intermittent rightward movement of the trough plate 2104, it can effectively cooperate with the boss 2201 to lift the right side of the trough plate 2104 around the hinge point between the trough plate 2104 and the slider 2103, thereby allowing the soil inside the trough plate 2104 to be poured into the inner side of the outer shell 23. The crushing rod 2401 then breaks up the poured soil. The conveying auger 24, in conjunction with the inclined inner shell 25, transports the broken soil upward and discharges it to the outer side of the trench.

[0019] Working principle: When using it, such as Figure 1-2 , Figure 5-6 and Figure 8-10As shown, the vehicle body 1 is first manually driven into the bottom of the trench beside the municipal road. Then, the piston driven by the cylinder 3 pushes the oil inside the first oil cylinder 4 downward, causing the telescopic component 5 to extend downward in a ring around the center of the second driven shaft 18. This, in turn, drives the fixed cylinder 6, rotating cylinder 7, outer cylinder 8, and excavator head 9 to extend downward simultaneously. This structure allows adjustment of the depth of the excavator head 9 when cleaning the trench. Then, the vehicle body 1 is started, and the servo motor 12 is activated to drive the main shaft 13 to rotate, driving the pinion 14, the large gear 15, and the first driven shaft 16 to rotate. This causes the first driven shaft 16 to drive the first sprocket mechanism 17, the second driven shaft 18, and the second driven shaft 16 to rotate simultaneously. Then, the rotating cylinder 7 rotates, and the weight of the gravity block 2801 can be used to rotate the rotating cylinder 7. The force is greater than the resistance of the excavator head 9 to the trench cleaning and excavation. The oil squeezed by the gravity block 2801 through the oil pipe 26, in conjunction with the oil chamber 1004 and the first connecting pipe 1003, compresses and extends the first telescopic sleeve 1002. Thus, under the rotation of the rotating drum 7, it effectively pushes the pulling block 1001, the outer cylinder 8, and the excavator head 9 clockwise, thereby effectively cleaning and excavating the trench soil. To prevent the excavator head 9 from damaging the rock layer during trench cleaning and excavation, if the excavator head 9 encounters protruding rocks in the trench, the resistance between the excavator head 9 and the rock is greater than the resistance between the excavator head 9 and the soil, and simultaneously greater than the weight of the gravity block 2801. This causes the excavator head 9, the outer cylinder 8, and the pulling block 1001 to work in conjunction with the first telescopic sleeve 1002 to extend. 02. The reverse motion redirects the protruding rock, effectively squeezing the oil inside the first telescopic sleeve 1002, along with the first connecting pipe 1003, oil chamber 1004, and oil pipe 26, into the second oil cylinder 27. This oil compression, in turn, causes the gravity block 2801 to press the second telescopic sleeve 2802 upwards. This, in conjunction with the second connecting pipe 2803, effectively squeezes the oil into the limiting frame 2804, causing the adjusting block 2806, along with the spring 2805, to extend to the right, adjusting the size of the stone frame 2's outlet. As the vehicle body 1 moves, the adjusting block 2806 controls the flow of crushed stone in the upper section of the foundation trench, ensuring it is laid precisely on the outer side of the upper section's protruding rock layer. The above structure can not only adaptively simulate the manual adjustment of the digging force of the excavator head 9 on the trench cleaning and excavation to ensure that the rock layer is not damaged during the trench cleaning and excavation, but also effectively adjust the size of the discharge port of the corresponding stone frame 2 by the resistance between the excavator head 9 and the protruding rocks in the trench. This allows the stone frame 2 to effectively lay crushed stone on the trench while also effectively laying a limited amount of crushed stone on the protruding rocks in the trench. This effectively ensures that the crushed stone laying area on the protruding rocks in the trench is flush with the crushed stone laying area in the trench. At the same time, it avoids the need for manual hand tools to clean and excavate the trench, thereby increasing the overall practicality and convenience, improving the efficiency of trench cleaning, reducing the amount of manual labor, and lowering labor costs. like Figure 1-4 and Figure 7 As shown, when the main shaft 13 rotates, it also drives the rotating plate 2101 to rotate, causing the connecting plate 2102 to drive the slider 2103 to move left and right in conjunction with the limiting plate 22. This effectively drives the slot plate 2104 to move left and right intermittently. Due to the speed difference between the pinion 14 and the gear 15, the slot plate 2104 can intermittently insert between the two excavators 9, thus effectively receiving the soil excavated from the excavators 9. Utilizing the intermittent rightward movement of the slot plate 2104, it can effectively cooperate with the boss 2201 to hold the slot plate 2104 in place. On the right side, the soil around the hinge joint between the trough plate 2104 and the slider 2103 is pushed upwards, allowing the soil inside the trough plate 2104 to be poured into the inner side of the outer shell 23. The soil is then broken up by the crushing rod 2401. The crushed soil is then transported upwards by the conveying auger 24 in conjunction with the inclined inner shell 25 and discharged to the outer side of the trench. This structure eliminates the need for manual tools to throw the soil out of the trench, further reducing labor and labor costs, while simultaneously improving the efficiency of the entire trench cleaning process. This completes a series of tasks.
