Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically a self-cleaning engineering road compaction machinery device. Background Technology

[0002] In road construction, compaction machinery is used to compact the road surface and make it smooth. During operation, soil and gravel adhere to the outer wall of the compaction roller. The self-cleaning device is used to remove the soil and gravel from the outer wall of the compaction roller. Usually, a scraper is used to clean the soil and gravel from the outer wall of the compaction roller to ensure the smoothness of the road surface.

[0003] When the scraper of the existing self-cleaning engineering road compaction machinery cleans the mud and gravel on the outer wall of the compaction wheel, the blade of the scraper needs to contact the outer wall of the compaction wheel to clean the mud and gravel. After working for a long time, the blade will wear down, and the contact between the blade and the outer wall of the compaction wheel will not be tight, resulting in poor cleaning effect.

[0004] Therefore, this utility model provides a self-cleaning engineering road compaction machine to solve the above problems. Utility Model Content

[0005] This utility model provides a self-cleaning engineering road compaction machinery device, which aims to solve the problems mentioned in the background art, such as the wear of the scraper blade after a long period of cleaning the compaction wheel with mud and gravel, and the poor contact between the blade blade and the outer wall of the compaction wheel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning engineering road compaction machinery device, including a support frame, compaction wheels rotatably mounted on both sides of the support frame, a lifting structure mounted on the support frame and corresponding to the compaction wheels, and a scraper mounted on the lifting structure;

[0007] The lifting structure includes two symmetrically mounted fixed shells on a support frame. A lead screw is rotatably mounted at the bottom of the inner cavity of each fixed shell. The two lead screws are threaded together to mount a lifting plate. A worm gear is mounted on the upper side of the outer wall of each lead screw. The lifting structure also includes a worm gear meshing with the worm gear. By setting up the lifting structure, the forward rotation of the worm gear drives the two worm gears to rotate synchronously. The worm gears drive the lead screws to rotate, and the two lead screws move the lifting plate downwards. The lifting plate moves the scraper downwards, allowing the worn scraper blade to re-contact the outer wall of the compaction wheel. This avoids the problem in existing self-cleaning engineering road compaction machinery where the scraper blade wears down after prolonged cleaning of the compaction wheel's outer wall, resulting in loose contact between the blade and the compaction wheel's outer wall. This improves the cleaning effect of the scraper on the compaction wheel's outer wall.

[0008] Preferably, the lifting plate is slidably mounted with a limit block via a slide groove, an elastic element is installed on the side wall of the right limit block, a connecting rod is installed on the opposite face of each pair of limit blocks, and a pull rod is installed on the side wall of the limit block.

[0009] The scraper has a rectangular tube installed on its end face, and the end face of the rectangular tube has a second opening corresponding to the connecting rod.

[0010] Preferably, the support frame includes a top plate and a fixed plate fixedly installed in the mounting groove. The top plate and the fixed plate are rotatably connected to both ends of the worm gear through connecting holes. Two vertical plates are installed on the bottom of the top plate and on the front and rear sides. The left and right vertical plates are rotatably installed with a rotating shaft connected to the compaction wheel through connecting holes.

[0011] Preferably, the upper end of the fixed shell is connected to the bottom of the top plate, and the upper end of the lead screw passes through the bottom of the top plate and the mounting groove in sequence, and is rotatably connected to the top plate.

[0012] Preferably, the left end of the worm gear passes through the fixing plate and is equipped with a crank, and the end face of the top plate is equipped with a handle.

[0013] Preferably, the lower end of the scraper is a sharp part, and the lower end of the scraper is rotatably connected to the outer wall of the compaction wheel.

[0014] Preferably, at least three slides and first openings are provided, the limiting block is adapted to the inner cavity of the rectangular tube, the lifting plate is provided with a connecting groove for installing the connecting rod, and the side wall of the lifting plate is provided with a through groove corresponding to the pull rod.

[0015] Beneficial effects: By setting up a lifting structure, the worm gear rotates forward, causing two worm wheels to rotate synchronously. The worm wheels drive the lead screw to rotate, and the two lead screws drive the lifting plate to move downward. The lifting plate then drives the scraper downward, allowing the worn scraper blade to re-contact the outer wall of the compaction wheel. This avoids the problem in existing self-cleaning engineering road compaction machinery where the scraper blade wears down after prolonged cleaning of the compaction wheel's outer wall, resulting in poor contact between the blade and the compaction wheel's outer wall. This improves the cleaning effect of the scraper on the outer wall of the compaction wheel. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] This embodiment provides a self-cleaning engineering road compaction machine, such as... Figure 1-5 As shown, the compaction machinery includes a support frame 1, compaction wheels 2 are rotatably mounted on both sides of the support frame 1, and a lifting structure 3 is mounted on the support frame 1 and corresponding to the compaction wheels 2. A scraper 4 is mounted on the lifting structure 3.

[0025] The lifting structure 3 includes two fixed shells 31 symmetrically mounted on the support frame 1. A lead screw 32 is rotatably mounted at the bottom of the inner cavity of the fixed shell 31. The two lead screws 32 are connected to a lifting plate 33 by threads. A worm gear 34 is mounted on the upper side of the outer wall of the lead screw 32. The lifting structure 3 also includes a worm 35 that meshes with the worm gear 34.

[0026] When in use, when the blade of scraper 4 is worn and no longer in contact with the outer wall of compaction wheel 2, the user drives the hand crank 351 to rotate clockwise. The hand crank 351 drives the worm gear 35 to rotate clockwise, the worm gear 35 drives the two worm wheels 34 to rotate synchronously, the worm wheels 34 drive the lead screw 32 to rotate, and the two lead screws 32 drive the two ends of the lifting plate 33 to move downward synchronously. The lifting plate 33 drives the scraper 4 to move downward, so that the worn blade of scraper 4 contacts the outer wall of compaction wheel 2 again. Then, the hand crank 351 is stopped to fix the position of scraper 4, realizing the air intake and removal of soil and gravel from the outer wall of compaction wheel 2. This avoids the problem that the blade of scraper 4 will wear down after a long time of cleaning the outer wall of compaction wheel 2, and the blade will not make tight contact with the outer wall of compaction wheel 2 when cleaning soil and gravel in existing self-cleaning engineering road compaction machinery. This improves the cleaning effect of scraper 4 on the outer wall of compaction wheel 2.

[0027] The worm gear 34 and worm 35 work together, and the worm gear 34 cannot actively drive the worm 35 to rotate, so that the cooperation between the two has self-locking property, ensuring that the vertical position of the scraper 4 will not move under non-human conditions.

[0028] In this embodiment, the support frame 1 includes a top plate 11 and a fixing plate 12 fixedly installed in the mounting groove 111. The top plate 11 and the fixing plate 12 are rotatably connected to both ends of the worm gear 35 through connecting holes. Two vertical plates 13 are installed on the bottom of the top plate 11 and on the front and rear sides. The two vertical plates 13 are rotatably installed with rotating shafts 14 connected to the compaction wheel 2 through connecting holes. The upper end of the fixing shell 31 is connected to the bottom of the top plate 11. The upper end of the screw 32 passes through the bottom of the top plate 11 and the mounting groove 111 in sequence and is rotatably connected to the top plate 11.

[0029] The upper end of the lead screw 32 passes through the bottom of the top plate 11 and the mounting groove 111 in sequence, and is rotatably connected to the top plate 11, so that the upper end of the lead screw 32 can be stably installed, and the function of the lifting structure 3 can be realized.

[0030] In this embodiment, the left end of the worm 35 passes through the fixing plate 12 and is equipped with a crank 351, and the end face of the top plate 11 is equipped with a handle 15; the lower end of the scraper 4 is a sharp part, and the lower end of the scraper 4 is rotatably connected to the outer wall of the compaction wheel 2.

[0031] A handle 15 is installed on the end face of the top plate 11, which facilitates the use of the compaction machinery.

[0032] Example 2

[0033] Unlike Embodiment 1, the scraper 4 of the existing self-cleaning engineering road compaction machinery is usually fixed to the equipment with multiple bolts. When the blade is damaged, it is inconvenient to quickly replace the blade, which increases the downtime of the compaction machinery. Therefore, the lifting plate 33 is slidably installed with the limit block 5 through the slide groove 331. The side wall of the right limit block 5 is equipped with an elastic element 6, the opposite surfaces of the two limit blocks 5 are equipped with connecting rods 7, and the side wall of the limit block 5 is equipped with a pull rod 8.

[0034] A rectangular tube 41 is installed on the end face of the scraper 4, and a second opening 411 corresponding to the connecting rod 7 is opened on the end face of the rectangular tube 41.

[0035] In use, the user pulls the lever 8 to the right, which moves the center limiting block 5. The center limiting block 5 is driven by the connecting rods 7 on both sides to move the connecting blocks 5 on both sides into the slide groove 331. The limiting block 5 moves out of the inner cavity of the rectangular cylinder 41 and separates from the rectangular cylinder 41. The user takes the scraper 4 and the rectangular cylinder 41 off together and replaces the scraper 4. The scraper 4 is driven to take multiple rectangular cylinders 41 into the corresponding first opening 332. The connecting rod 7 passes through the second opening 411 and enters the inner cavity of the rectangular cylinder 41. At this time, the lever 8 is released. Under the reset action of the elastic element 6, the elastic element 6 drives multiple limiting blocks 5 into the inner cavity of the rectangular cylinder 41 to lock the rectangular cylinder 41, realizing the quick replacement of the scraper 4. This avoids the problem that the scraper 4 of the existing self-cleaning engineering road compaction machinery is usually fixed on the equipment with multiple bolts. When the blade is damaged, it is inconvenient to quickly replace the blade. This reduces the downtime of the compaction machinery and helps to improve work efficiency.

[0036] In this embodiment, at least three slide grooves 331 and first openings 332 are provided. The limiting block 5 is adapted to the inner cavity of the rectangular tube 41. The lifting plate 33 is provided with a connecting groove 333 for installing the connecting rod 7. The side wall of the lifting plate 33 is provided with a through groove 334 corresponding to the pull rod 8.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
