Technical Field
[0001] This utility model relates to the technical field of highway maintenance, specifically to a crushed stone homogenization and spreading device. Background Technology
[0002] Crushed stone spreading is a common maintenance method in highway maintenance. By laying a layer of crushed stone on the road surface, it can effectively cure or reduce road surface defects such as poor asphalt content, looseness, minor cracking, rutting, and subsidence, thereby extending the service life of the highway and improving driving comfort.
[0003] A crushed stone homogenizing and spreading device for highway maintenance, disclosed in publication number CN209243513U, includes a box body. A feeding plate is fixedly connected to the top of the box body. Active crushing piles and auxiliary crushing piles are movably connected inside the box body near the feeding plate. There are three auxiliary crushing piles. Pile teeth are fixedly connected to the outer surfaces of both the active and auxiliary crushing piles. A first main drive gear is fixedly connected to one end of each active crushing pile.
[0004] The aforementioned document states that by setting active and auxiliary crushing piles inside the housing, the device can further crush the gravel, preventing large chunks of stone from clogging the inside of the housing and causing uneven spreading. This improves the effectiveness of the gravel homogenizing and spreading device, making the gravel spread more evenly.
[0005] However, the above-mentioned documents show that a large amount of dust is generated during the crushing and discharge of gravel, which seriously pollutes the environment. In addition, the filter plates in the above-mentioned documents are fixed, and the falling gravel can easily clog the filter holes and affect the filtration effect. Therefore, we propose a gravel homogenization and spreading device to solve the problems mentioned above. Utility Model Content

[0025] Please see Figure 1-5A dust suppression assembly 20 is installed above the feeding box 1. The dust suppression assembly 20 includes a water supply tank 2001, which is fixed above the feeding box 1. A water inlet 2002 is provided on one side of the upper part of the water supply tank 2001. A water pump 2003 is fixed above the feeding box 1. One end of the water pump 2003 is connected to the water supply tank 2001 through a water suction pipe 2004. The other end of the water pump 2003 is connected to a drain pipe 2005. A water distribution pipe 2007 is connected to the end of the water pump 2003. The end of the water distribution pipe 2007 is connected to a first water collection pipe 2 fixed at both ends of the discharge port 4. 008, the use of atomizing nozzles 2009 on the surface of the first water collection pipe 2008 facilitates dust suppression of the crushed stone discharged below the discharge port 4. A connecting pipe 2006 is connected to the surface of the drain pipe 2005, and the end of the connecting pipe 2006 is connected to the second water collection pipe 2010 embedded in the inner wall of the feed port 3.

[0026] Working principle: First, the feeding box 1 is connected to the vehicle via the traction rod 2. When in use, the rotating motor 6 is turned on, causing the crushing teeth 8 on the fixed cylinder 7 of the connecting shaft 5 to rotate. This, in conjunction with the fixed teeth 19 fixed inside the feeding box 1, facilitates the crushing of the crushed stone. The surface of the connecting shaft 5 is connected to the rotating shaft 16 via the transmission belt 18, so that the cam 17 on the surface of the rotating shaft 16 rotates. This causes the cam 17 to squeeze the filter screen 10, so that the filter screen 10, in conjunction with the spring 12, slides inside the first groove 11 and the second groove 13 inside the feeding box 1, facilitating the screening and filtering of the crushed stone. The filter screen 10 is set at an angle, which makes it easy to discharge the filtered crushed stone into the collection frame 15 through the second through hole 14, while the crushed stone that falls off the filter will be discharged through the discharge port 4.
[0027] In use, the water pump 2003 on the dust suppression component 20 can be turned on, so that the water pump 2003 draws water out of the water supply tank 2001 through the water suction pipe 2004, and discharges the water into the first water collection pipe 2008 through the drain pipe 2005 and the water distribution pipe 2007. This allows the atomizing nozzle 2009 on the surface of the first water collection pipe 2008 to spray the discharged gravel to suppress dust. The surface of the drain pipe 2005 is connected to the second water collection pipe 2010 through the connecting pipe 2006, and in conjunction with the use of the atomizing nozzle 2009 on the surface of the second water collection pipe 2010, it is convenient to suppress the dust generated by crushing at the feed inlet 3, thereby improving the effectiveness of the device.
