Abstract
Description
Technical Field
[0001] This utility model relates to the field of road surface breaking technology, specifically a road surface breaking device for road repair. Background Technology
[0002] As road surfaces age, their surface performance and load-bearing capacity decline, causing vehicles to damage the weakened surfaces and resulting in road surface breakage. Therefore, road surface repair is necessary. However, when there are many damaged areas, simple repairs cannot restore the road surface's performance, and the repaired surface has a short lifespan and high maintenance costs. Therefore, when there are many damaged areas on the road surface, the entire damaged road surface is usually repaved.
[0003] The existing technology disclosure number CN213896698U describes a road surface breaking device that uses a drilling rig to drill holes and break up the road surface. However, the breaking surface between the drill bit and the road surface is small during drilling, requiring multiple drilling operations. Moreover, after drilling and breaking up, the broken road surface consists of large fragments that are difficult to clean up, so the fragments still need to be broken up again, which is time-consuming, labor-intensive, and has low breaking efficiency. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology in terms of low crushing efficiency and to provide a road surface crushing device for road repair.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a road surface breaking device for road repair, comprising a base plate, a fixed block fixedly connected to the top of the base plate, a slot formed on the fixed block, and a movable plate movably connected within the slot, a breaker hammer fixedly connected to the front end of the movable plate, the slot on the base plate being located below the breaker hammer, a motor and a battery fixedly connected to the top of the base plate, a transmission rod provided at the rear end of the movable plate, a fixed gear fixedly connected to both the end of the transmission rod and the output shaft of the motor, and a transmission gear meshing between the two gears, a cover fixedly connected to the top of the base plate, a rectangular slot formed on the front side of the cover, the motor and battery being located within the cover, the movable plate passing through the rectangular slot, two wheels movably connected to the left and right sides of the base plate, the two wheels being arranged front and rear, and a Y-shaped traction rod fixedly connected to the rear side of the base plate.
[0006] As described above, there are several support plates, and each of the support plates is fixedly connected to a breaker hammer at its end and movably connected in a slot. The breaker hammers are divided into two groups, with the two groups of breaker hammers spaced apart and adjacent breaker hammers staggered vertically.
[0007] As described above, the transmission rod includes a rotating rod, which is horizontally arranged above the movable plate. Both ends of the rotating rod are movably connected to the cover. Several U-shaped fixed rods are fixedly connected to the rotating rod, and two adjacent fixed rods are centrally symmetrical.
[0008] As described above, a partition is fixedly connected inside the cover, and the partition is located behind the motor. A suction cup is fixedly connected to the bottom of the base plate, and a ventilation pipe is fixedly connected to the rear side of the suction cup. The rear end of the ventilation pipe extends through the base plate into the cover and is located behind the partition. A first fan is fixedly connected inside the ventilation pipe, and a ventilation slot is opened at the top of the cover.
[0009] As described above, the enclosure is equipped with an air filter, and the air filter has sliding grooves on both the front and rear sides. Limiting plates that match the sliding grooves are fixedly connected to the rear side of the partition and the inner wall of the rear side of the enclosure.
[0010] As described above, the front side of the cover is open and has a baffle. Screws are movably connected to the four corners of the baffle and are threaded to the cover. A second fan is fixedly connected to the baffle and is located above the air filter. A ventilation slot is provided on the front side of the cover.
[0011] As described above, a metal mesh is fixedly connected inside the suction bucket, several pyramidal metal spikes are fixedly connected to the bottom of the breaker hammer, and U-shaped splash guards are fixedly connected to the top and bottom of the base plate near the front side.
[0012] Compared with existing technologies, this road surface breaking device for road repair has the following advantages:
[0013] I. This utility model uses a motor to drive a transmission rod to rotate, which in turn drives the breaker hammer to swing up and down, thereby breaking up the road surface. Multiple breaker hammers are provided and divided into two groups. The multiple breaker hammers in a single group increase the breaking surface during each break, thus increasing the degree of road surface fragmentation. This results in smaller fragments of the road surface after breakage, which are easier to clean up. Furthermore, the alternating hammering of the two groups of breaker hammers reduces the swing interval of the breaker hammers, thereby improving the breaking efficiency.
[0014] II. This utility model provides a suction cup and a ventilation pipe at the bottom of the base plate, and a partition is provided inside the cover to form an independent cavity, allowing the end of the ventilation pipe to extend into the cavity. A first fan is installed inside the ventilation pipe, which can suck the dust generated when the road surface is broken into the cavity and filter it through an air filter, thereby reducing the dust generated when the road surface is broken.
[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

Detailed Implementation
[0021] 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.
[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a road surface breaking device for road repair, including a base plate 1, a fixing block 12 fixedly connected to the top of the base plate 1, a slot opened on the fixing block 12, and a movable plate 11 movably connected in the slot, a breaker hammer 3 fixedly connected to the front end of the movable plate 11, the slot opened on the base plate 1 located below the breaker hammer 3, a motor 15 and a storage battery 16 fixedly connected to the top of the base plate 1, a transmission rod provided at the rear end of the movable plate 11, a fixed gear 17 fixedly connected to the end of the transmission rod and the output shaft of the motor 15, and a transmission gear 21 meshing between the two gears, a cover 2 fixedly connected to the top of the base plate 1, a rectangular slot opened on the front side of the cover 2, the motor 15 and the storage battery 16 are both located inside the cover 2, the movable plate 11 passes through the rectangular slot, two wheels 5 movably connected to the left and right sides of the base plate 1, and the two wheels 5 are arranged front and rear, and a Y-shaped traction rod 6 fixedly connected to the rear side of the base plate 1.
[0023] Based on the overall structure of the device, it can be moved by wheels 5, and thus connected to the rear of an engineering vehicle via a tow bar 6. The engineering vehicle drives the device forward to break up the entire road surface. Power is provided by the battery 16 to start the motor 15. The motor 15 drives the transmission rod to rotate through the fixed gear 17 and the transmission gear 21. When the transmission rod rotates, it pushes the movable plate 11 to deflect, causing the breaker hammer 3 to rise. Then the transmission rod separates from the movable rod, and the breaker hammer 3 falls and strikes the road surface under its own weight, thereby breaking up the road surface. The cover 2 covers the motor 15 and the battery 16 to provide protection and prevent damage to the motor 15 and the battery 16.
[0024] like Figure 1 , 3 As shown, there are several support plates, and each support plate is fixedly connected to a breaker hammer 3 at its end and movably connected in the slot. The breaker hammers 3 are divided into two groups, with the two groups of breaker hammers 3 spaced apart and the adjacent breaker hammers 3 are staggered vertically. The transmission rod includes a rotating rod 13, which is horizontally arranged above the movable plate 11. Both ends of the rotating rod 13 are movably connected to the cover 2. Several U-shaped fixing rods 14 are fixedly connected to the rotating rod 13, and the adjacent fixing rods 14 are centrally symmetrical.
[0025] By setting up several hydraulic breakers 3 to increase the hammering surface and expand the crushing range, the motor 15 drives the rotating rod 13 to rotate through the fixed gear 17 and the transmission gear 21, and drives the fixed rod 14 to rotate forward counterclockwise. When the fixed rod 14 rotates, it contacts the top of the movable plate 11 and pushes the rear end of the movable plate 11 to deflect downward, thereby causing the hydraulic breaker 3 to swing upward. As the rotating rod 13 rotates, the fixed rod 14 slides along the movable plate 11 to its rear end until it separates. When the fixed rod 14 separates from the movable plate 11, the hydraulic breaker 3 falls and hammers the road surface under its own gravity, thereby crushing the road surface. By dividing the several hydraulic breakers 3 into two groups and driving the two groups of hydraulic breakers 3 to swing alternately through the several fixed rods 14, the time interval between the up and down swing of the hydraulic breakers 3 is shortened, thereby improving the crushing efficiency.
[0026] like Figure 3 , 4 As shown, a partition 18 is fixedly connected inside the cover 2, and the partition 18 is located behind the motor 15. A suction cup 8 is fixedly connected to the bottom of the base plate 1, and a ventilation pipe 9 is fixedly connected to the rear side of the suction cup 8. The rear end of the ventilation pipe 9 extends through the base plate 1 into the cover 2 and is located behind the partition 18. A first fan 20 is fixedly connected inside the ventilation pipe 9, and a ventilation slot is opened at the top of the cover 2. An air filter 19 is provided inside the cover 2. Slide grooves are opened on both the front and rear sides of the air filter 19. Limiting plates matching the slide grooves are fixedly connected to the rear side of the partition 18 and the inner wall of the rear side of the cover 2.
[0027] The suction bucket 8 and the first fan 20 can absorb the air at the crushing point, so that the dust generated when the road surface is crushed can enter the cover 2 through the ventilation pipe 9 along with the air. The air is then filtered by the air filter 19 to remove the dust from the air, thereby preventing a large amount of dust from flying during the crushing process.
[0028] like Figure 1 , 3 As shown, the front of the cover 2 is open and a baffle 7 is provided on the front of the cover 2. Screws are movably connected to the four corners of the baffle 7 and are threaded to the cover 2. A second fan 22 is fixedly connected to the partition 18. The second fan 22 is located above the air filter 19 and a ventilation slot is provided on the front of the cover 2.
[0029] The front opening of the cover 2 and the baffle 7 make it easy to open the cover 2, so that the motor 15, battery 16 and other components inside the cover 2 can be maintained. The baffle 7 can be quickly removed and installed with screws. The second fan 22 and the ventilation slot can drive the air flow in the space in front of the partition 18, so as to facilitate the heat dissipation of the motor 15 and battery 16 when they are working, and prevent the motor 15 and battery 16 from burning out.
[0030] like Figure 1 , 2 As shown, a metal mesh 10 is fixedly connected inside the suction bucket 8, and several pyramidal metal spikes are fixedly connected to the bottom of the breaker hammer 3. U-shaped splash guards 4 are fixedly connected to the top and bottom of the base plate 1 near the front side.
[0031] The metal mesh 10 blocks the gravel to prevent it from splashing into the suction bucket 8. The metal spikes make it easier for the breaker hammer 3 to break the road surface when it strikes. The splash guard 4 prevents gravel from flying outwards and injuring workers when the road surface is broken.
[0032] Working principle: In use, the device can be moved by the wheels 5, and can be connected to the rear of a construction vehicle via the tow bar 6. The construction vehicle drives the device forward to break up the entire road surface. Power is provided by the battery 16 to start the motor 15. The motor 15 drives the rotating rod 13 to rotate through the fixed gear 17 and the transmission gear 21, which in turn drives the fixed rod 14 to rotate. The fixed rod 14 pushes the movable plate 11 to deflect, causing the breaker hammer 3 to rise. Then the fixed rod 14 separates from the movable rod, and the breaker hammer 3 falls under its own weight and strikes the road surface, thus breaking up the road surface. The road surface is divided into two groups of breaker hammers 3. When the fixed rod 14 rotates, it pushes the two groups of breaker hammers 3 to swing alternately, thereby shortening the swing interval of the breaker hammers 3 and improving the crushing efficiency. The cover 2 covers the motor 15 and the battery 16 to provide protection and prevent damage to the motor 15 and the battery 16. The suction bucket 8, ventilation pipe 9, first fan 20 and air filter 19 absorb and filter the dust generated during crushing to prevent dust from flying and affecting the working environment. The metal mesh 10 prevents the crushed stone from splashing into the suction bucket 8 and ventilation pipe 9, and the splash guard 4 prevents the crushed stone from splashing outward and injuring people.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
