Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of street cleaning equipment, more particularly, it relates to an environmentally-friendly ground cleaning vehicle and a cleaning method. BACKGROUND

[0002] With the acceleration of urbanization, street cleaning work has gradually become the focus of social attention. In the traditional cleaning method, it mainly relies on manual cleaning or basic mechanical equipment, but these methods have defects such as low efficiency, incomplete cleaning effect, and high labor cost. Especially in large public areas, such as squares, parks, and commercial districts, the ground cleaning task is more difficult, and the performance requirements of the cleaning equipment are also correspondingly increased.

[0003] In the prior art field, small cleaning vehicles usually use rotating cleaning brushes to sweep garbage into the bottom of the vehicle body and use recycling devices for collection, thereby realizing automatic cleaning. However, this technology still has certain deficiencies. For example, small cleaning vehicles generally use rotating brushes to sweep garbage into the recycling device at the bottom of the vehicle, but for garbage with strong ground adhesion (such as wet sticky paper and ground plastic bags), the shear force generated by the rotation of the brush cannot effectively overcome the adhesion of the garbage to the ground, resulting in failure of the garbage to be peeled off; when dealing with large-area scattered garbage (such as fallen leaves and floating objects), the brush structure cannot effectively collect the garbage, causing cleaning blind spots. These problems result in incomplete cleaning work, which requires secondary manual processing, thereby increasing the overall burden of cleaning work. SUMMARY

Various processes or components can be omitted, substituted, or added according to various examples. Additionally, features described with respect to some examples can be combined in other examples. Example One

[0019] Please refer to Figs. 1-2The utility model provides an environmental protection ground cleaning vehicle, include: car body 10, cleaning mechanism 20, spray mechanism 30 and collection mechanism 40, wherein, cleaning mechanism 20 is located at the bottom of the front end of car body 10, it is used for in the cleaning vehicle movement process, the garbage located at the both sides of car body 10 is swept to the bottom position of car body 10, and it is convenient for subsequent collection mechanism 40 to recycle. Spray mechanism 30 is located at the front end of car body 10, it is used for the water mist spray to the cleaning area of cleaning mechanism 20, and spray mechanism 30 specifically includes the water tank 301 fixed at the front end of car body 10 and two spray heads 302 towards the initiative cleaning assembly, is equipped with the conveying piece in water tank 301, and the conveying piece is connected with spray head 302, is used for conveying water source to spray head 302, sets up spray mechanism 30, one aspect is to utilize water to increase garbage weight, avoids cleaning mechanism 20 to lift garbage to the effective cleaning area outside, and the other aspect is to clean the cleaning end of cleaning mechanism 20. Collection mechanism 40 is located on car body 10, it is used for recycling the garbage that is swept to the bottom of car body 10 and is recycled, and it specifically includes the suction force driving element in car body 10 and the recovery suction head connected with suction force driving element, generates suction force through suction force driving element, makes the recovery suction head have suction force and sucks the garbage below it, and finally is conveyed to the recovery bin in car body 10. The rear end of the bottom of car body 10 is equipped with the automatic telescopic floor mopping mechanism 50, when needing to further clean the ground after cleaning, can put down floor mopping mechanism 50 and clean the ground. Since floor mopping mechanism 50, collection mechanism 40 and spray mechanism 30 all belong to the conventional technical means in the field, so the specific structure and working process will not be introduced in detail here.

[0020] Specifically, please refer to Figs. 3-4 Cleaning mechanism 20 includes a multi-directionally adjustable active cleaning assembly, an extension driving assembly, and an auxiliary cleaning assembly connected to the extension driving assembly and located at the front end of the active cleaning assembly; the auxiliary cleaning assembly includes a cleaning scraper 201, a cleaning comb plate 202, and a state switching driving element. The cleaning scraper 201 is provided with comb grooves 203 adapted to the cleaning comb plate 202, and the cleaning comb plate 202 is connected to the state switching driving element.

[0021] In the implementation of the present application, according to the actual need of the ground to be cleaned, the corresponding cleaning mode can be selected. For example, when the ground has strong adsorption of garbage such as dust, paper scraps, etc., or it is difficult to clean the garbage to the preset position by simple cleaning, the auxiliary scraping mode can be used. In this mode, the cleaning comb plate 202 is embedded in the comb slot 203 to form an integrated scraper structure with the cleaning scraper 201. At this time, the stretching drive assembly can drive the integrated scraper structure to reciprocate along the ground from outside to inside. The bottom of the integrated scraper structure can shovel the garbage adsorbed on the ground and scrape the garbage into the recycling area of the collection mechanism 40, and then the collection mechanism 40 recycles the garbage. On the other hand, when the ground has a large amount of scattered garbage such as fallen leaves, plastic bags, etc., the auxiliary collection mode can be used. In this mode, the state switching drive member drives the cleaning comb plate 202 to expand and move, so that the cleaning comb plate 202 slides to one end of the cleaning scraper 201, thereby increasing the length of the cleaning scraper 201 and forming an integrated comb plate structure with the cleaning scraper 201. The stretching drive assembly drives the integrated comb plate structure to reciprocate, and pushes a large amount of garbage accumulated on the ground into the recycling area of the collection mechanism 40 for recycling by the collection mechanism 40.

[0022] Please refer to Figs. 4-6 In order to achieve the above functions, the present application designs the following scheme: The state switching drive member includes a linear extension source 204 fixed on the cleaning scraper 201, a sliding support connected with the extension end of the linear extension source 204, and a contraction locking member provided on the cleaning scraper 201. The cleaning scraper 201 is provided with a sliding groove 205, and the cleaning comb plate 202 slides with the sliding support and the sliding groove 205. When the cleaning comb plate 202 moves to the position aligned with the comb slot 203, the cleaning comb plate 202 is hidden in the comb slot 203 by the contraction locking member.

[0023] Specifically, the linear telescopic source 204 can be an electric push rod, the telescopic end of which is in sliding connection with the cleaning comb plate 202. The sliding support includes a sliding body 206 sliding in a sliding groove 205, the cleaning comb plate 202 is in sliding connection with the sliding body 206, and an elastic body 207 is arranged between the two, which can be a metal spring that can be compressed when the cleaning comb plate 202 is in the retracted state. The retraction locking member includes an electromagnet 208 arranged on the cleaning scraper 201 and a magnetic body 209 arranged on the cleaning comb plate 202. The electromagnet 208 is powered by an external power supply and is controlled by an external switch to turn on and off. When switched to the auxiliary scraping mode, the cleaning comb plate 202 moves to the position aligned with the comb slot 203, and then the electromagnet 208 starts to be powered on to generate a magnetic attraction force on the magnetic body 209, so that the cleaning comb plate 202 moves to the side of the comb slot 203, and finally hides in the comb slot 203.

[0024] In the implementation of the above-mentioned state switching member, if it is necessary to adjust the auxiliary cleaning assembly from the auxiliary scraping mode to the auxiliary collecting mode, the power supply line of the electromagnet 208 needs to be disconnected, so that the magnetic attraction force of the electromagnet 208 on the magnetic body 209 disappears. At this time, under the action of the elastic potential energy of the elastic body 207, the cleaning comb plate 202 and the magnetic body 209 jointly move away from the cleaning scraper 201 until the elastic body 207 is completely reset, and the cleaning comb plate 202 is completely separated from the comb slot 203. Subsequently, through the elongation action of the linear telescopic mechanism, the cleaning comb plate 202 linearly slides along the side of the cleaning scraper 201, and the sliding body 206 also linearly slides along the sliding groove 205 to limit the cleaning comb plate 202. When the end of the cleaning comb plate 202 moves to the end of the cleaning scraper 201, a uniform comb structure is formed with the comb slot 203, the linear telescopic mechanism stops elongation, and the cleaning scraper 201 and the cleaning comb plate 202 form an integrated elongated comb plate, thereby being able to push a large amount of garbage outside the vehicle body 10 and improve the cleaning efficiency of the cleaning vehicle. If it is necessary to return to the auxiliary scraping mode, the cleaning comb plate 202 is moved to the position aligned with the comb slot 203 through the contraction action of the linear telescopic mechanism, and then the electromagnet 208 is powered on to generate a magnetic attraction force on the magnetic body 209, so that the cleaning comb plate 202 is retracted and embedded in the comb slot 203. In this way, the state switching drive member provided by the present application realizes the automatic switching of the use state of the auxiliary cleaning assembly, improves the adaptability and flexibility of the cleaning vehicle. During use, the operator only needs to select the appropriate cleaning mode according to the condition of the ground garbage, and the efficient ground cleaning operation can be realized. In addition, the design of the state switching drive member makes the switching process between the cleaning comb plate 202 and the cleaning scraper 201 smooth and smooth, avoiding damage to the cleaning vehicle or the ground caused by improper switching, and further improving the reliability and durability of the cleaning vehicle.

[0025] Please refer to Figs. 2-3 , the active cleaning assembly includes a base 210 detachably mounted on the bottom of the vehicle body 10, a multidirectional adjustment driving member 211 provided on the base 210, and two cleaning brush heads 212 symmetrically provided on both sides of the base 210. The multidirectional adjustment driving member 211 is connected with the two cleaning brush heads 212, wherein the cleaning brush is provided with a driving motor 217 for driving the brush head to rotate. The multidirectional adjustment driving member 211 includes a two-way air cylinder, two hinged rod assemblies, and two third electric push rods. The cleaning brush head 212 is hinged to the base 210 through the hinged rod, and the third electric push rod is hinged between the cleaning brush head 212 and the base 210. The two telescopic ends of the two-way air cylinder are connected with the two hinged rod assemblies respectively. By telescoping the two-way air cylinder, the distance between the two cleaning brush heads 212 can be adjusted, and by telescoping the third electric push rod, the height of the cleaning brush head 212 can be adjusted. The multidirectional adjustment driving member 211 can not only flexibly and freely adjust the left and right positions of the cleaning brush head 212 in the horizontal direction, but also accurately control the height position change of the cleaning brush head 212 in the vertical direction. This all-round adjustment function enables the cleaning device to freely adjust the working position of the cleaning brush head 212 according to different needs of the actual use scene. Whether it is for special areas with uneven ground or different surfaces that need to change the cleaning force and angle, it can perfectly adapt to different surfaces, thereby greatly improving the practicality and application range of the cleaning equipment, and meeting the diversified cleaning needs of users.

[0026] Please refer to Fig. 3 , in order to realize the reciprocating swing action of the auxiliary cleaning assembly, the present application designs an extension driving assembly, specifically: the extension driving assembly includes a support arm 213 obliquely installed on the base 210, a swing arm 214 rotating on the support arm 213, and a connecting seat 215 hinged with the swing arm 214. A second electric push rod 216 is hinged between the connecting seat 215 and the swing arm 214. The support arm 213 and the connecting seat 215 are each provided with a motor 217 for driving the swing arm 214 and the auxiliary cleaning assembly to rotate.

[0027] In use, the above-mentioned stretching drive assembly can drive the swing arm 214 connected thereto to rotate axially through the low-speed forward and reverse rotation of the motor 217 on the support arm 213, so that the auxiliary cleaning assembly can stably and accurately complete the swing action, thereby ensuring the cleaning effect. Meanwhile, the auxiliary cleaning assembly can adjust its ground clearance according to different ground heights and garbage accumulation conditions through the telescopic function of the second electric push rod 216, so that the cleaning process will not cause dead angles or damage to the ground due to improper height. The motor 217 on the connecting seat 215 further enhances the adaptability of the auxiliary cleaning assembly, and by adjusting the horizontal angle, the garbage on the ground can be more effectively cleaned, especially the garbage that is difficult to be directly scraped. In addition, the design of the motor 217 driving the auxiliary cleaning assembly to continuously rotate provides strong support for cleaning stubborn stains and entangled objects, ensuring that the cleaning vehicle can maintain high cleaning efficiency when facing various complex ground conditions. Therefore, the design of the stretching drive assembly can enable the auxiliary cleaning assembly to be adjusted in multiple directions according to actual needs, thereby increasing the flexibility of the cleaning vehicle and significantly improving the cleaning efficiency.

[0028] Based on the above-mentioned scheme, it should be noted that the auxiliary cleaning assembly designed by the present application, in the auxiliary scraping mode, the cleaning comb plate 202 is hidden in the comb slot 203, forming an integrated scraper structure with the cleaning scraper 201, and the bottom edge is smooth, which can closely fit the ground, effectively scrape and clean small garbage with strong adsorption force, such as dust, paper scraps, etc., to ensure that the ground is clean without dead angles. At the same time, the integrated scraper structure can reciprocate along the ground from outside to inside through the driving of the stretching drive assembly, simulating the action of manual cleaning, which not only improves the cleaning efficiency but also ensures the cleaning quality.

[0029] In the auxiliary collection mode, the cleaning comb plate 202 is expanded to form an integrated comb plate structure with the cleaning scraper 201, and the comb design can increase the contact area with the ground garbage and improve the efficiency of garbage collection. Especially for a large amount of light garbage such as fallen leaves and plastic bags on the ground, the comb plate structure can easily push these garbage into the recyclable area of the collection mechanism 40, avoiding the problem of low cleaning efficiency of traditional cleaning vehicles when facing a large amount of scattered garbage. Embodiment two

[0030] In addition, as another embodiment of the present application, based on the aforementioned cleaning vehicle, the present application further proposes a ground cleaning method, which comprises the following operation steps: Step S100: Select the appropriate cleaning mode according to the type and distribution of garbage on the ground to be cleaned. If the ground mainly contains small garbage with strong adsorption force, such as dust, paper scraps, etc., the auxiliary scraping mode is selected; if the ground contains a large amount of scattered garbage, such as fallen leaves, plastic bags, etc., the auxiliary collection mode is selected.

[0031] Step S200: in the auxiliary scraping mode, the cleaning mechanism 20 of the cleaning vehicle is started to make the cleaning comb plate 202 embedded in the comb slot 203 to form an integrated scraper structure with the cleaning scraper 201. Then, the integrated scraper structure is driven by the stretching driving assembly to reciprocate along the ground from outside to inside, so as to scrape the garbage adsorbed on the ground into the recovery area of the collection mechanism 40.

[0032] Step S300: in the auxiliary collection mode, the cleaning comb plate 202 is driven by the state switching driving member to expand and become active, so as to form an integrated comb plate structure with the cleaning scraper 201. Then, the integrated comb plate structure is driven by the stretching driving assembly to reciprocate, so as to push the garbage accumulated on the ground into the recovery area of the collection mechanism 40.

[0033] Step S400: during the cleaning process, according to the ground height and garbage accumulation condition, the height of the auxiliary cleaning assembly from the ground is adjusted by the telescopic function of the second electric push rod 216, so as to ensure that there is no cleaning dead angle or damage to the ground due to improper height during the cleaning process.

[0034] Step S500: at the same time, the spraying mechanism 30 is started to spray water mist on the cleaning area of the cleaning mechanism 20, so as to increase the weight of the garbage by using water to avoid the garbage being lifted by the cleaning mechanism 20 to the effective cleaning area, and to clean the cleaning end of the cleaning mechanism 20.

[0035] Step S600: after the cleaning is completed, the garbage cleaned by the cleaning mechanism 20 to the preset position at the bottom of the vehicle body 10 is recovered by the collection mechanism 40, and finally transported to the recovery bin in the vehicle body 10, so as to complete the entire cleaning process.

[0036] By using the ground cleaning method provided by the present application, the operator only needs to select the appropriate cleaning mode according to the condition of the garbage on the ground, so as to realize efficient ground cleaning operation, which greatly improves the cleaning efficiency and cleaning quality. At the same time, the cleaning method also has the advantages of simple operation and strong adaptability, and can be widely applied to various places requiring ground cleaning.

[0037] The embodiments of the present application are described above, but the present application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative but not limiting, and many forms can be made by those skilled in the art under the inspiration of the present application, which all belong to the protection of the present application.
