Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a dry intelligent suction and sweeping device with environmental protection function. Background Art

[0002] In modern cleaning operations, the application of intelligent suction and sweeping devices has become a trend, especially in factories, warehouses, urban sanitation and other fields. Compared with traditional manual cleaning methods, intelligent suction and sweeping devices are used more and more frequently because of their advantages such as high efficiency, strong adaptability and environmental friendliness.

[0003] However, most of the intelligent suction and sweeping devices on the market are mainly wet suction and sweeping. Especially in sanitation equipment, wet sweepers are more common. Their working principle relies on spraying clean water on the suction and sweeping parts to complete the cleaning task. This method is effective in removing sticky stains and dust, but this method has obvious defects: on the one hand, continuous spraying of clean water will significantly increase the humidity in the working area, which may not only destroy the dry environment required for product processing and storage in certain specific environments (such as factories and warehouses), but may also cause workers to quickly re-contaminate the ground when they frequently walk on wet ground.

[0004] In contrast, the dry suction sweeper cleans without spraying clean water, avoiding the above problems. In the field of sanitation, dry sweepers are favored because they do not cause secondary pollution. However, dry suction sweepers are prone to generate a large amount of dust during the suction and sweeping process, especially in dry and windy environments. The dust problem is particularly serious, which seriously pollutes the urban environment. To solve this problem, there are schemes that try to increase the dust suction range and reduce dust by increasing the volume of the dry suction sweeper. For example, the dry suction sweeper disclosed in Chinese patent CN201520670001.7 has made significant improvements to the structural layout of the existing dry suction sweeper, solving the problems of the existing dry suction sweeper on the road, the poor filtering effect, the difficulty of cleaning, the incomplete dust suction and the inability to effectively sweep the edge of the road, and the dust removal efficiency is improved. However, this method causes the width and volume of the device to be too large, which is not suitable for operation in narrow spaces such as urban streets and complex road conditions, thereby limiting its scope of application.

[0021] A dry intelligent suction and sweeping device with environmental protection function, such as Figure 1-Figure 10As shown, it includes an automatic vacuum sweeper body 1, an observation radar 11, a waste hopper 12, a rotating block 21, a mounting plate 22, a suction disc 23, a hollow rotating shaft 26, an air jet spiral 27, a scraper 28 and a traction mechanism; the automatic vacuum sweeper body 1 is sequentially installed with the observation radar 11 and the waste hopper 12, wherein the observation radar 11 uses a laser scanning radar of the LDS-25BDM-2 model for unmanned sweepers; the automatic vacuum sweeper body 1 is built with a suction device 13 and a blast device 14, and the outlet end of the suction device 13 is connected to the waste hopper 12; the automatic vacuum sweeper body 1 Two rotating blocks 21 are rotatably connected at the bottom; a mounting plate 22 is slidably connected to each of the two rotating blocks 21; a traction mechanism is connected to the automatic vacuum sweeping vehicle body 1, and the traction mechanism switches the unfolded state and the retracted state of the mounting plate 22; three suction discs 23 are fixedly connected to each of the two mounting plates 22; a collecting pipe 241 is fixedly connected to each of the two mounting plates 22; the two collecting pipes 241 are respectively connected to all the suction discs 23 on the same mounting plate 22; a shielding cover 231 is fixedly connected to the bottom of each suction disc 23 to prevent large-volume debris from being sucked into the suction disc 23 ; A telescopic air extraction pipe 242 is connected between the two collecting pipes 241 and the suction device 13 in the automatic suction and sweeping vehicle body 1; a shunt pipe 251 is fixedly connected to each of the two mounting plates 22; a telescopic air supply pipe 253 is connected between the two shunt pipes 251 and the blast device 14 in the automatic suction and sweeping vehicle body 1; the two shunt pipes 251 are respectively connected to an annular air supply disc 252 corresponding to the number and position of the suction disc 23; each annular air supply disc 252 is rotatably connected to a hollow rotating shaft 26; each hollow rotating shaft 26 is provided with a plurality of inlet ports The air inlet structure 260 of each hollow rotating shaft 26 is respectively connected to the corresponding annular air delivery disk 252; each hollow rotating shaft 26 is fixedly connected with five air jet cyclones 27, and the inner space of the air jet cyclone 27 is connected to the inner space of the hollow rotating shaft 26; each air jet cyclone 27 is provided with a plurality of air jet outlet structures 270, and all air jet outlets on the same mounting plate 22 are set to be inclined structures facing the same rotation direction; each air jet cyclone 27 is fixedly connected with a scraper 271; each scraper 271 is fixedly connected with a brush 272.

[0022] like Figure 3 and Figure 5 As shown, the traction mechanism includes an electric screw 31, a traction slider 32 and a pull rod 33; the electric screw 31 is rotatably connected to the bottom of the automatic vacuum sweeping vehicle body 1; the traction slider 32 is slidably connected to the bottom of the automatic vacuum sweeping vehicle body 1; the traction slider 32 is screwed to the electric screw 31; and a pull rod 33 is rotatably connected between the traction slider 32 and the two mounting plates 22.

[0023] The present invention provides a dry intelligent vacuum sweeping device with environmental protection function, such as Figure 1 and Figure 2As shown, initially, the suction and sweeping work is performed in the unfolded state. At this time, the suction discs 23 and the jet cyclones 27 on the two mounting plates 22 are distributed in a V shape. The air blowing device 14 in the automatic suction and sweeping vehicle body 1 conveys airflow to the hollow rotating shafts 26 in each annular air delivery disc 252 through the telescopic air delivery pipe 253 and the diverter pipe 251, and the airflow enters each jet cyclone 27 and is ejected outward through the jet port structure 270. The reverse thrust generated when the airflow is ejected outward from the inclined jet port structure 270 will push the jet cyclone 27 to drive the hollow rotating shaft 26 to rotate rapidly, so that the airflow is ejected downward in all directions toward the ground, and the dust on the ground is blown to all directions by the ejected airflow. At the same time, the suction device 13 in the automatic suction and sweeping vehicle body 1 performs suction work on each suction disc 23 above the jet cyclone 27 through the telescopic air delivery pipe 242 and the collecting pipe 241, so that the dust blown up by the airflow is promptly sucked through the suction disc 23 by the suction device 13 and sent to the waste hopper 12.

[0024] Each jet cyclone 27 on each hollow rotating shaft 26 and the suction disc 23 above together form an independent suction and sweeping small unit. Several groups of independent suction and sweeping small units are distributed in a V shape on the two mounting plates 22, and the automatic suction and sweeping vehicle body 1 simultaneously drives all the suction and sweeping small units to jointly suck and sweep the dust on the ground. The several groups of independent suction and sweeping small units on the two mounting plates 22 perform semi-enclosed suction and sweeping work on the dust on the ground in a V-shaped distribution state, so that the dust that cannot be sucked away by the suction disc 23 can also be captured and sucked by the suction disc 23 on the adjacent suction and sweeping small unit in time, which not only increases the suction and sweeping area of ​​the ground, but also improves the dust capturing effect of all suction and sweeping small units, greatly reduces the generation of dust, and achieves an environmental protection effect.

[0025] Specifically, in the present invention, the automatic suction and sweeping vehicle body drives all the suction and sweeping small units at the same time to ensure that they work synchronously; when a certain suction disc fails to remove all the dust, the suction discs on the adjacent suction and sweeping small units can capture and remove the residual dust in time. Its mechanism of reducing dust is as follows: 1. Increasing the suction and sweeping area: The V-shaped layout increases the suction and sweeping area in contact with the ground, so that more dust can be adsorbed and processed in the first time. This large-area coverage effectively reduces the possibility of dust spreading in the space; 2. Improving dust capture efficiency: The design of independent suction and sweeping small units and the synergy between them ensure that dust can be effectively removed even in small areas or hard-to-reach corners. The mutual cooperation of the suction discs enables any escaping dust to be quickly captured by adjacent units, greatly reducing the chance of secondary dust; 3. Reducing air disturbance: By adjusting the airflow intensity and direction of the jet vortex, the air disturbance generated during the cleaning process can be minimized, thereby avoiding stirring up the deposited dust; this gentle cleaning method helps to maintain a stable working environment and reduce unnecessary dust.

[0026] In addition, the jet cyclone 27 will also drive the scraper 271 and the brush 272 to rotate together, and the scraper 271 and the brush 272 will scrape up and brush away the debris on the ground that is difficult to be blown up by the airflow. At the same time, the suction plate 23 will suck away the scraped and brushed debris in time.

[0027] When the observation radar 11 of the dry intelligent vacuum sweeping device with environmental protection function of the present invention detects that the front will enter a narrow space, the electric screw 31 drives the traction slider 32 to move backward along the automatic vacuum sweeping vehicle body 1, and the traction slider 32 pulls the pull rod 33 to drive the mounting plate 22 to move backward along the rotating block 21. At the same time, the traction slider 32 pulls the pull rod 33 to drive the mounting plate 22 and the rotating block 21 to rotate backward. Fig.11 As shown, the suction disc 23 and the jet coil 27 on the mounting plate 22 are switched to the retracted state for suction and sweeping, thereby reducing the suction and sweeping working area of ​​the suction disc 23 and the jet coil 27, and improving the passability and use effect of the dry intelligent suction and sweeping device with environmental protection function in a narrow space of the present invention. Example 2

[0028] On the basis of Example 1, Figure 1-Figure 11 As shown, a scraper strip 28 is fixedly connected to the rear side of each of the two mounting plates 22 of the present embodiment; a fixed block 41 is slidably connected to the bottom of the automatic suction and sweeping vehicle body 1; a suction bucket 43 is fixedly connected to the fixed block 41; a suction pipe 44 is commonly connected between the suction bucket 43 and the suction device 13 in the automatic suction and sweeping vehicle body 1; the suction bucket 43 is composed of a rotating baffle 431 and a folding sheet 432; two rotating baffles 431 are rotatably connected to the fixed block 41; the two rotating baffles 431 are rotatably connected to an adjacent scraper strip 28 respectively; a folding sheet 432 is fixedly connected between the upper sides of the two rotating baffles 431; a folding sheet 432 is also fixedly connected between the lower sides of the two rotating baffles 431; a return spring 42 is fixedly connected between the fixed block 41 and the automatic suction and sweeping vehicle body 1.

[0029] In the process of the automatic vacuum sweeper body 1 driving the suction plate 23 and the jet cyclone 27 to vacuum the ground, when the two scraper strips 28 on the automatic vacuum sweeper body 1 are as shown in FIG. Fig.11 In the retracted state shown in the figure, the folding piece 432 between the two scraping strips 28 is in the unfolded state, at this time, the two scraping strips 28 respectively surround the left and right sides of all the suction discs 23, and the dust that is not completely sucked away by the suction discs 23 will be gathered to the suction bucket 43 by the scraping strips 28 to the rear, and at the same time, the suction device 13 in the automatic suction and sweeping vehicle body 1 will promptly suck the dust collected in the suction bucket 43 into the waste hopper 12 through the suction pipe 44; when the two scraping strips 28 on the automatic suction and sweeping vehicle body 1 are switched to the state shown in the figure Figure 1In the expanded state shown, the folding piece 432 between the two scraping strips 28 is switched to a folded state, and the two scraping strips 28 moving forward pull the suction bucket 43 to drive the fixed block 41 to move forward along the automatic suction and sweeping vehicle body 1, and the fixed block 41 drives the return spring 42 to compress forward to generate a return compression elastic force, so that the suction bucket 43 remains between the two scraping strips 28 to collect the collected dust, thereby improving the cleaning and collection efficiency of the dust, so that the device does not need to move back and forth multiple times within the cleaning range, and can also reduce dead angles during the cleaning process, thereby improving the cleaning efficiency. Example 3

[0030] On the basis of Example 2, Figure 1-Figure 11 As shown, the front sides of the two mounting plates 22 of this embodiment are each fixed with a stopper 29; when the automatic vacuum sweeper body 1 drives the suction plate 23 and the jet cyclone 27 to vacuum the ground, when the two scraper strips 28 on the automatic vacuum sweeper body 1 are switched to the positions shown in FIG. Figure 1 In the unfolded state shown in FIG. 1 , the two blocking rods 29 block the front of all the suction discs 23 in a V-shaped structure, so that the debris that is too large to be sucked by the suction discs 23 is intercepted by the two blocking rods 29. As the debris intercepted between the two blocking rods 29 accumulates more and more, the two scraping strips 28 on the automatic suction and sweeping vehicle body 1 will be switched to the V-shaped structure as shown in FIG. Fig.11 In the retracted state shown in FIG. 1 , the two blocking rods 29 will also be switched to the position shown in FIG. Fig.11 In the retracted state shown, the two baffle bars 29 are switched to a V-shaped structure with a smaller angle, so that the debris intercepted and accumulated between the two baffle bars 29 will move along the two baffle bars 29 toward the suction hopper 43, and the suction device 13 in the automatic suction and sweeping vehicle body 1 will promptly suck the debris collected in the suction hopper 43 through the suction pipe 44 and collect it into the waste hopper 12, thereby completing the cleaning and collection of the debris.
