A sweeper with a blowing function

Abstract

This utility model provides a sweeper with a blowing function, belonging to the field of sweeper technology. It solves the problem that existing sweepers cannot handle litter such as fallen leaves, waste paper, and fruit peels on sidewalks. This utility model of a sweeper with a blowing function includes a frame, a fan, a suction pipe, an air outlet assembly, and a blowing pipe. In this utility model, the air outlet of the blowing pipe faces one side of the frame, and the blowing pipe is flush with the frame. Thus, the blowing pipe blows air towards the edge of the road surface. Therefore, when the sweeper is traveling on the sidewalk where there are trees or obstacles at the edge, the blowing pipe blows air directly under the trees or around the obstacles, causing debris under the trees or around the obstacles to be directly blown onto the road, where a sweeper can then directly clean it up. This quickly removes debris under trees, making it convenient for people to clean and effectively improving cleaning efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of sweeper technology and relates to a sweeper with a blowing function. Background Technology

[0002] Accumulated litter such as fallen leaves, waste paper, and fruit peels is a common sight on city sidewalks. While the carefully planted trees on both sides of the street add greenery and shade, they significantly hinder efficient cleaning. Conventional large-scale sweepers, due to their bulk and fixed operating radius, face severe limitations in their operating space due to the presence of drooping branches, close proximity to tree trunks, and protruding roots, making it difficult to reach key areas such as around tree roots and under shrubs. Therefore, sanitation work has to adopt a time-consuming and laborious two-step process: First, sanitation workers must manually collect various types of litter scattered in corners by hand, using brooms and dustpans, bending over and weaving through the gaps between trees; then, these collected items must be gathered and transported to nearby open and unobstructed areas (such as intersections or small squares). Only after this time-consuming pre-cleaning and transfer process is completed can large sweepers finally process the accumulated litter. This model directly leads to two drawbacks: on the one hand, cleaning efficiency is severely reduced, as tasks that could originally be completed by machines in one go are manually divided, and time-consuming manual processes slow down the overall process, significantly weakening the speed advantage that mechanization should have; on the other hand, labor costs increase significantly, as high-intensity, highly repetitive (frequent bending over) and extremely time-consuming pre-cleaning work is carried out in a confined space, requiring more manpower to complete, which undoubtedly increases the overall burden of sanitation operations against the backdrop of continuously rising labor costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sweeper with a blowing function that can handle litter such as fallen leaves, waste paper, and fruit peels on sidewalks.

[0004] The objective of this utility model can be achieved through the following technical solution: a sweeper with a blowing function, comprising:

[0005] A chassis, on which a fan and an air intake pipe are mounted;

[0006] An air outlet assembly is located at one end of the vehicle frame. The air outlet assembly is connected to a fan. An air blowing pipe is provided on the side of the air outlet assembly. The air intake pipe, the fan, and the air outlet assembly form an air duct. The air outlet of the air blowing pipe faces the ground on one side of the sweeper.

[0007] In the aforementioned cleaning machine with a blowing function, the blower is provided with a connecting cover for connecting the air outlet assembly.

[0008] In the aforementioned cleaning machine with a blowing function, the air outlet assembly includes an air collector hood, which has an air inlet for connecting to the connecting hood.

[0009] In the aforementioned cleaning machine with a blowing function, the side of the air collecting hood is provided with an air collecting hood for connecting the air blowing pipe, and the end of the air suction pipe away from the blower passes through the vehicle frame.

[0010] In the aforementioned cleaning machine with a blowing function, the bottom end of the air collecting hood is provided with an air control hole, and the bottom end of the air collecting hood is provided with a sealing component for controlling the opening or closing of the air control hole.

[0011] In the above-mentioned cleaning machine with blowing function, the sealing assembly includes a sealing plate, one side of the sealing plate is hinged to the air collector cover, and both sides of the sealing plate are provided with limiting ears. The bottom of the air collector cover is provided with a limiting plate corresponding to the limiting ears. The two limiting ears are respectively attached to the adjacent limiting plates, and the limiting ears and the limiting plates are connected by bolts.

[0012] In the aforementioned cleaning machine with a blowing function, both of the limiting ears are located between two limiting plates, and each limiting plate is provided with a limiting groove, wherein a bolt passes through the corresponding limiting groove, and a nut is installed on each bolt.

[0013] In the above-mentioned cleaning machine with blowing function, two shaft tubes are provided on one side of the sealing plate, and a through shaft is movably installed inside the shaft tube. One end of the through shaft extends out of the shaft tube, and the bottom of the air collecting cover is provided with the same number of fixing ears as the through shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, when the blower is started, outside air is drawn in, passes through the blower, and is blown out through the blower pipe. The outlet of the blower pipe faces one side of the vehicle frame, and the blower pipe is flush with the vehicle frame. Thus, the blower pipe blows air towards the edge of the road. Therefore, when the sweeper is traveling on the sidewalk and there are trees or obstacles at the edge of the sidewalk, the blower pipe blows air directly under the trees or around the obstacles, so that the debris under the trees or around the obstacles can be blown directly onto the road, and then the sweeper on the road can directly sweep up the debris. In this way, the debris under the trees or around the obstacles can be quickly removed, which is convenient for people to clean and can also effectively improve the cleaning efficiency.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1 — Figure 5 As shown, the sweeper with blowing function of this utility model includes a frame 100, a fan 110, a suction pipe 111, an air outlet assembly 200, and a blowing pipe 300.

[0025] In this invention, miscellaneous items refer to leaves, waste paper, and fruit peels.

[0026] The frame 100 is equipped with a fan 110 and a suction pipe 111; an air outlet assembly 200 is located at one end of the frame 100, and the air outlet assembly 200 is connected to the fan 110. A blowing pipe 300 is located on the side of the air outlet assembly 200. The suction pipe, fan, and air outlet assembly form an air duct. The air outlet of the blowing pipe faces the ground on one side of the sweeper. The top of the fan is equipped with a collection chamber 120 for collecting garbage. The suction pipe 111 is connected to the fan through the collection chamber. When the fan operates, outside air is drawn in through the suction pipe, and garbage on the road is also drawn in and transported to the collection chamber. The garbage then remains in the collection chamber, while the air entering the collection chamber enters the fan. Furthermore, when outside air... Air is drawn in by the fan 110, passes through the air outlet assembly 200, and is blown out by the blower pipe 300. In this invention, the air outlet of the blower pipe faces the ground on one side of the sweeper. Thus, the blower pipe 300 blows air towards the edge of the road. Therefore, when the sweeper is traveling on the sidewalk and there are trees or obstacles at the edge of the sidewalk, the blower pipe 300 blows air directly under the trees or around the obstacles, so that the debris under the trees or around the obstacles can be blown directly onto the road, and then the sweeper on the road can directly sweep up the debris. In this way, the debris under the trees or around the obstacles can be quickly removed, which is convenient for people to clean and can also effectively improve the cleaning efficiency. Secondly, it can also make full use of the air discharged from the duct.

[0027] The fan 110 is provided with a connecting cover 112 for connecting the air outlet assembly 200. The air outlet assembly 200 includes an air collecting cover 210. The air collecting cover 210 is provided with an air inlet (not marked in the figure) for connecting the connecting cover 112. The side of the air collecting cover 210 is provided with an air gathering cover 310 for connecting the air blowing pipe 300. The end of the suction pipe 111 away from the fan 110 passes through the frame 100. When the fan 110 is working, the outside air will pass through the suction pipe 111, the fan 110, the connecting cover 112, the air collecting cover 210, the air gathering cover 310, and the air blowing pipe 300 in sequence, and finally blow air to the outside through the air blowing pipe 300.

[0028] The bottom end of the air collecting cover 210 is provided with an air control hole 211. The bottom end of the air collecting cover 210 is provided with a sealing component 400 for controlling the opening or closing of the air control hole 211. When the sealing component 400 no longer blocks the air control hole 211 or opens the air control hole 211 to a certain extent, the air entering the air collecting cover 210 will be divided into two parts. One part will move towards the air control hole 211 and be discharged to the outside through the air control hole 211. The remaining part will still be discharged to the outside through the blower pipe 300. In this way, the wind force in the blower pipe 300 can be effectively weakened, thereby achieving the purpose of controlling the wind force of the blower pipe.

[0029] Furthermore, the sealing assembly 400 includes a sealing plate 410, one side of which is hinged to the air collector cover 210. Limiting ears 411 are provided on both sides of the sealing plate 410. A limiting plate 212 corresponding to the limiting ears 411 is provided at the bottom of the air collector cover 210. The two limiting ears 411 respectively abut against adjacent limiting plates 212. The limiting ears 411 and the limiting plates 212 are connected by bolts 420. Each bolt 420 is fitted with a nut 421. Specifically, the nut 421 is connected to the corresponding limiting ear 411. During the process of opening the air control hole 211, the bolt 420 needs to be loosened first to reduce the friction between the limiting ear 411 and the limiting plate 212. Then, the sealing plate 410 can be rotated to open the air control hole 211. When the opening range of the air control hole 211 reaches the predetermined requirement, the bolt 420 can be tightened to increase the friction between the limiting plate 212 and the limiting ear 411, thereby limiting the movement of the limiting ear 411 relative to the limiting plate 212, and thus controlling the opening range of the sealing plate 410, that is, controlling the opening range of the air control hole 211.

[0030] Both limiting ears 411 are located between two limiting plates 212. Each limiting plate 212 is provided with a limiting groove 212a. The bolt 420 passes through the corresponding limiting groove 212a. During the rotation of the sealing plate 410, because the bolt 420 passes through the limiting plate 212 and the limiting ear 411, the bolt 420 will move synchronously with the limiting ear 411. At this time, the limiting groove 212a plays the role of avoiding the bolt 420, and at the same time, it can also guide the movement of the bolt 420, so that the sealing plate 410 can be rotated stably.

[0031] Two shaft tubes 430 are provided on one side of the sealing plate 410. A through shaft 431 is movably installed inside the shaft tube 430. One end of the through shaft 431 extends out of the shaft tube 430. The bottom of the air collecting cover 210 is provided with the same number of fixing ears 213 as the through shaft 431. The two through shafts 431 pass through the adjacent fixing ears 213 respectively. The two fixing ears 213 are located on both sides of the sealing plate 410, the two shaft tubes 430 are located between the two fixing ears 213, and the two through shafts 431 are located on the same straight line. During the installation process, when the two through shafts 431 pass through the corresponding fixing ears 213 and people flip the sealing plate 410, the sealing plate 410 will flip around the straight line where the through shafts 431 are located.

[0032] A spring 432 is provided between one end of the shaft 431 and the inner wall of the shaft tube 430. A through rod 433 is provided on the shaft 431. A through groove 434 is provided on the side of the shaft tube 430, and the through rod 433 passes through the through groove 434. The shaft tube 430 is provided with a connecting lug 435 for connecting the sealing plate 410. During installation, the person needs to hold the through rod 433 and move the shaft 431 into the corresponding shaft tube 430 through the through rod 433. At this time, the spring 432 is compressed so that the shaft 431... 1. The through hole (not shown in the figure) on the fixed ear 213 for passing through the through shaft 431 can be aligned. Then, the force acting on the through rod 433 is removed, and the spring 432 will push the through shaft 431 to move towards the fixed ear 213 so that the through shaft 431 can pass smoothly through the through hole. When the through rod 433 abuts against one end of the through groove 434, the through shaft 431 stops moving. In this way, it is not only convenient for people to install the sealing plate 410 on the bottom of the air collector cover 210, but also to realize that the sealing plate 410 is hinged to the bottom of the air collector cover 210.
