Description

Technical Field

[0001] The utility model discloses a highway efficient suction and sweeping device, belonging to the technical field of highway maintenance. Background Art

[0002] With the rapid economic development, the traffic flow has increased sharply, and highways, expressways and freeways have become increasingly dense. During the rapid development of roads, the requirements for road cleaning are getting higher and higher, and the road cleaning pressure is also increasing day by day. The increase in traffic flow may cause various sundries on the road, and these sundries pose a serious threat to driving safety. In order to quickly discover and collect sundries, the road sweeper needs to continuously check and clean in time. Existing road sweepers suck various sundries into the cleaning and dust collection box through the suction port. Since there are many types of sundries, larger sundries require greater suction force at the suction port. Therefore, existing road sweepers all adopt larger power engines and larger fans. The operating power of existing road sweepers for cleaning is relatively large, which greatly wastes fuel consumption power and increases the noise. The operation efficiency of this pure suction type road sweeper is low. If the vehicle speed is increased, many sundries will pass by without being sucked into the road sweeper.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] The present utility model provides a high-efficiency road sweeping and suction device. A brush roller assembly that cooperates with an adjustment assembly is installed inside the protective cover assembly near the two rear universal wheels. An auger shaft is installed inside the protective cover assembly near the front universal wheel. A fan assembly is installed outside the protective cover assembly corresponding to the output port of the auger shaft assembly. During operation, debris will enter the brush roller sweeping area along the rubber scraping edge. The brush roller rotates in the reverse direction. At this time, most of the debris and dust are thrown above the auger, and a small part is bounced back by the rubber scraping edge. The brush roller repeatedly sweeps, and all will be thrown above the auger. The dust is strongly sucked into the side centrifugal fan port to ensure that the sweeping operation is carried out in a dust-free state. The debris is input into the suction port of the fan assembly through the auger. Under the action of the centrifugal force of the fan assembly and the suction force of the dust collection box fan, the debris will instantly enter the dust collection box body. This kind of sweeping, conveying, centrifugal force and suction force are not affected by the vehicle speed and the amount of debris, making the sweeping operation faster, more efficient and more time-saving.

[0036] Among them: The driving brush roller adjusting assembly includes a first adjusting swing arm 302 hinged to one end of the adjusting shaft 319. A driving brush roller motor 304 is installed on one side of the first adjusting swing arm 302. A first external hexagonal sleeve 305 is sleeved on the main shaft of the driving brush roller motor 304 and positioned by a first hexagonal nut 306. The main shaft of the driving brush roller motor 304 is in limit fit with the brush piece pressing plate 403 at one end of the brush roller shaft cylinder 402 through the first external hexagonal sleeve 305. The other end of the first adjusting swing arm 302 is connected to one end of a first short chain 301 near the top. The other end of the first short chain 301 is connected to one end of a first height adjusting bolt 303. The other end of the first height adjusting bolt 303 passes through a first connecting plate 205 arranged on the top of the protective cover top cover 201 and is in fit and positioning with a first adjusting nut 316. Sliding grooves 204 are respectively arranged at both ends of the protective cover top cover 201. The body of the driving brush roller motor 304 close to the main shaft can slide along the sliding groove 204 at one end of the protective cover top cover 201.

[0037] The above-mentioned driven height adjustment assembly includes a second adjustment swing arm 307 with one end hinged to the other end of the adjustment shaft 319. An adjustment swing bearing sleeve 308 is installed on the side of the second adjustment swing arm 307. An adjustment swing shaft 310 is passed through the adjustment swing bearing sleeve 308. Tapered roller bearings 309 that cooperate with the adjustment swing bearing sleeve 308 are respectively sleeved on both sides of the shoulder of the adjustment swing shaft 310. A sealing felt ring 313 is sleeved on the adjustment swing shaft 310 to cooperate with the inner side of one end of the adjustment swing bearing sleeve 308. The tapered roller bearings 309 are hermetically installed in the adjustment swing bearing sleeve 308 through bearing end covers 312. A second hexagonal sleeve 315 that is in limit cooperation with the brush plate pressing plate 403 at the other end of the brush roller shaft cylinder 402 is sleeved on the adjustment swing shaft 310. The second hexagonal sleeve 315 is limited by a second hexagonal nut 314 that cooperates with the adjustment swing shaft 310. The other end of the second adjustment swing arm 307 is connected to one end of a second short chain 311 near the top. The other end of the second short chain 311 is connected to one end of a second height adjustment bolt 318. The other end of the second height adjustment bolt 318 passes through a second connecting plate 202 arranged at the top of the protective cover top plate 201 and cooperates with a second adjustment nut 317 for positioning. The side of the adjustment swing bearing sleeve 308 close to the second hexagonal sleeve 315 can slide along the sliding groove 204 at the other end of the protective cover top plate 201.

[0038] During use, when the brush roller assembly 400 encounters an obstacle, one end of the brush roller assembly 400 is lifted, and the other end is also lifted simultaneously through the adjustment shaft 319, realizing the synchronous function of lifting and lowering at both ends. The relative height of the brush roller assembly 400 from the ground is achieved by rotating the first adjustment nut 316 and the second adjustment nut 317 on the first height adjustment bolt 303 and the second height adjustment bolt 318 to pull the short chain. During operation, the drive brush roller motor 304 in the first adjustment swing arm 302 drives the brush roller assembly 400 to rotate through the first hexagonal sleeve 305.

[0039] One end of the auger shaft 802 is driven to rotate by an auger shaft drive motor 801. The high-efficiency road suction and sweeping device of the present application is installed at the tail of the work vehicle. The device is supported by the front universal wheels 600 and the rear universal wheels 100 on the ground to ensure the relative position of the high-efficiency road and highway suction and sweeping device. During operation, as the work vehicle moves forward, the brush roller rotates clockwise. On the right side in the vehicle traveling direction, when looking at the end of the brush roller shaft, through the action of the friction and centrifugal force of the brush roller, the sundries on the road are thrown towards the auger shaft. As the vehicle moves forward, the rubber shovel blade takes advantage of the soft characteristics of the rubber, and various sundries on the road surface can pass through smoothly. When the sundries thrown by the brush roller do not reach a certain height and do not enter the auger guard plate, the rubber shovel blade will block the sundries, and the brush roller will repeatedly throw them until they enter the auger guard plate.

[0040] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples herein.
