Description

Technical Field

[0001] The present application relates to the technical field of road patching machines, and more specifically, to a small road patching machine. Background Art

[0002] After a road is opened to traffic, it will develop various road surface diseases after being subjected to long-term pressure from vehicles and erosion from the outdoor environment. Among them, cracks are one of the most common, most likely to occur, and earliest-occurring diseases among all types of road damage. Cracks in the road surface not only affect the appearance of the road and the comfort of driving, but also easily expand to cause structural damage to the road surface and shorten the service life of the road surface. Therefore, when cracks appear in the road surface, they need to be repaired with crack repair equipment to maintain the normal use of the road surface.

[0003] The document with the prior art publication number CN217923012U provides a highway repair device. When the staff sprays the repair agent onto the cracks on the highway pavement, the motor can be started. When the motor is started, it can drive the second rotating rod to rotate. The rotation of the second rotating rod can drive one of the gears to rotate. At this time, the first gear can drive another gear to rotate, thereby driving one of the first rotating rods to rotate. At the same time, the rotation of the second rotating rod can drive one of the transmission wheels to rotate, thereby driving another transmission wheel to rotate through the belt. The rotation of the other transmission wheel can drive another first rotating rod to rotate. The rotation of the first rotating rod can drive the installation frame to rotate. The rotation of the installation frame can drive the insertion block to rotate through the threaded rod. The rotation of the insertion block can drive the installation plate to rotate. The rotation of the installation plate can drive the sliding rod to rotate. The rotation of the sliding rod can drive the sliding block to rotate. The rotation of the sliding block can drive the supporting rod to rotate. The rotation of the supporting rod can drive the scraper to rotate, so that the repair fluid can be scraped into the crack to prevent waste.

[0004] Although the road patching machine has many beneficial effects, the following problems still exist: when the scraper is in contact with the ground for a long time, it will produce greater wear, and when the scraper is replaced in the above patent, multiple parts need to be replaced at the same time, and it is difficult to quickly replace the worn scraper alone, which easily increases the maintenance cost of the road patching machine. In view of this, we propose a small road patching machine. Utility Model Content

[0005] The embodiment of the present application provides a small road patching machine, which solves the technical problem in the prior art that when replacing a scraper, it is necessary to replace multiple parts at the same time, and it is difficult to quickly replace the worn scraper alone, which easily increases the maintenance cost of the road patching machine.

[0009] The scraper mechanism comprises a support plate, the top of the support plate is fixedly connected to the bottom end of the fixing rod, and the bottom of the support plate is detachably connected to a scraper, so that the staff can quickly replace the scraper that is severely worn.

[0010] By adopting the above technical solution and setting up a scraper mechanism, after the scraper is worn, the staff can quickly disassemble and replace the severely worn scraper separately without replacing a large number of parts, thereby facilitating the reduction of the maintenance cost of the road repair machine.

[0011] Optionally, a fixed plate is fixedly connected to one side of the bottom of the support plate, and two sliding bars are symmetrically fixedly connected to one side of the fixed plate. Both sides of the scraper are provided with sliding grooves for slidingly cooperating with the sliding bars, and the sliding bars are located in the sliding grooves, so that the staff can quickly remove the scraper.

[0012] By adopting the above technical solution and providing a fixed plate and a slide bar, when the scraper is pulled to move in a direction away from the fixed plate, the slide bar can gradually move out of the slide groove, thereby facilitating the staff to remove the scraper.

[0013] Optionally, a through groove is opened on one side of the support plate, movable blocks are elastically connected to both sides of the through groove, and a baffle is fixedly connected to one side of the movable block through a connecting rod, so as to prevent the scraper from being separated from the slide bar at will.

[0014] By adopting the above technical solution, by setting the baffle and the fixed plate, the scraper can be easily fixed between the fixed plate and the baffle, so that the scraper is blocked by the fixed plate and the baffle and supported by the slide bar, so that the scraper will not move at will.

[0015] Optionally, a guide rod for blocking the movable block is fixedly connected in the through slot, and the movable block is slidably sleeved on the outside of the guide rod, thereby preventing the movable block from escaping from the through slot.

A second mounting box 9 is installed on one side of the first mounting box 8. A fixing rod is connected to the inner side of the second mounting box 9 through a connecting block 10. A scraping mechanism 3 is provided at the bottom end of the fixing rod for collecting the repair agent into the crack.

[0031] The scraper mechanism 3 includes a support plate 31, the top of the support plate 31 is fixedly connected to the bottom of the fixed rod, and the bottom of the support plate 31 is detachably connected to a scraper 32, so that the staff can quickly replace the scraper 32 that is severely worn and reduce maintenance costs.

[0032] Reference Figure 1 Slots are provided on both sides of the top of the cart 1, bearings are installed in the slots, and the output shaft of the motor 7 is located in the bearings, so that the output shaft of the motor 7 can drive the first installation box 8 to rotate.

[0033] Reference Figure 2 and Figure 3 A fixing plate 33 is fixedly connected to one side of the bottom of the support plate 31, and two slide bars 34 are symmetrically fixedly connected to one side of the fixing plate 33. Slide grooves for slidingly cooperating with the slide bars 34 are provided on both sides of the scraper 32. The slide bars 34 are located in the slide grooves, so that the staff can quickly remove the scraper 32.

[0034] Reference Figure 2 and Figure 4 A through slot is provided on one side of the support plate 31, and movable blocks 37 are elastically connected to both sides of the through slot. A baffle 36 is fixedly connected to one side of the movable block 37 through a connecting rod 35, thereby preventing the scraper 32 from being separated from the slide bar 34 at will.

[0035] Reference Figure 1 and Figure 2 The cross-sections of the slide bar 34 and the slide groove are both T-shaped, so as to prevent the scraper 32 from moving vertically at the bottom of the support plate 31.

[0036] Reference Figure 3 A guide rod 39 for blocking the movable block 37 is fixedly connected in the through slot, and the movable block 37 is slidably sleeved on the outside of the guide rod 39, thereby preventing the movable block 37 from escaping from the through slot.

[0037] Reference Figure 4 Springs 38 are fixedly connected on both sides of the inner wall of the through groove. The spring 38 is sleeved on the outside of the guide rod 39. One end of the spring 38 is fixedly connected to the other side of the movable block 37, so as to prevent the movable block 37 from moving at will.

[0038] Reference Figure 4 The cross section of the connecting rod 35 is U-shaped, which makes it easy for the staff to pull the connecting rod 35 to drive the baffle 36 to move.

[0039] Reference Figure 2 A support block is slidably connected to the inside of the first installation box 8, a first threaded groove is penetrated on one side of the support block, and two second threaded grooves are penetrated on both sides of the first installation box 8. The support block is connected to the first installation box 8 through a first threaded rod, so that the staff can adjust the height of the second installation box 9, and then adjust the height of the scraper 32 to ensure that the bottom of the scraper 32 will not contact the ground when scraping is not needed.

[0041] The implementation principle of a small road patching machine in the embodiment of the present application is as follows: when the scraper 32 is worn, the staff can pull the two connecting rods 35 to move in a direction away from each other, and the movement of the connecting rod 35 can drive the movable block 37 and the baffle 36 to move, and the movement of the movable block 37 can squeeze the spring 38. When the two baffles 36 move to the specified position, the staff can pull the scraper 32 to move the scraper 32 in a direction away from the fixed plate 33 until the scraper 32 is separated from the slide bar 34, and the scraper 32 can be quickly removed. , and then the staff can place the new scraper 32 at the bottom of the support plate 31, and align the slide groove with the slide bar 34 to insert it, so that the slide bar 34 enters the slide groove until the new scraper 32 abuts against the fixed plate 33. The staff can then loosen the connecting rod 35 to allow the squeezed spring 38 to return to its original position and rebound, driving the movable block 37 to return to its original position and move, thereby driving the connecting rod 35 and the baffle 36 to move until the two baffles 36 abut against each other. At this time, the scraper 32 is fixed at the bottom of the support plate 31, which makes it easy for the staff to quickly replace the scraper 32.

[0042] The embodiment of the present application provides a small road patching machine. By setting up a scraper mechanism 3, after the scraper 32 is worn, the staff can quickly disassemble and replace the severely worn scraper 32 separately without replacing other parts, thereby reducing the maintenance cost of the road patching machine.
