[0046] The term "plurality" used in the present application refers to two or more (including two).
[0047] Reference below Figure 1-Figure 9 A fallen leaf cleaning device 100 according to an embodiment of the present invention is described.
[0048] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present application provides a fallen leaf cleaning device 100 , including: a collecting shovel 10 , a conveying assembly 20 and a collecting bin 30 .
[0049] Among them, the collecting shovel 10 includes: a shovel body 11 and a spiral mechanism 12 arranged in the shovel body 11, the spiral mechanism 12 is suitable for rotating to gather the fallen leaves in the middle area of the collecting shovel 10, one end of the conveying component 20 is located in the collecting shovel 10, and is arranged adjacent to the middle area of the collecting shovel 10, the conveying component 20 has a plurality of conveying parts 21, and the plurality of conveying parts 21 are suitable for moving from one end of the conveying component 20 to the other end in sequence, and the conveying parts 21 are suitable for entraining at least part of the fallen leaves in the collecting shovel 10, the collecting bin 30 is located on the rear side of the collecting shovel 10, the other end of the conveying component 20 extends to the collecting bin 30 (such as extending to the top of the collecting bin 30, or extending to one side of the collecting bin 30), and the collecting bin 30 has an open mouth to facilitate the fallen leaves to fall into.
[0050] Specifically, the fallen leaf cleaning device 100 can be arranged at the front end of a vehicle 200 (such as a sanitation vehicle). Figure 7 and Figure 8 As shown, the fallen leaves cleaning device 100 arranged at the front end of the vehicle 200 can be switched between a cleaning position and a storage position. In the cleaning position, the collecting shovel 10 falls down and can scoop up the fallen leaves on the ground. In order to extend the service life of the collecting shovel 10, it can be arranged that when the collecting shovel 10 is in the cleaning position, there is still a certain gap between it and the ground, and a detachable cleaning plate (such as a polyurethane plate) can be further provided on the collecting shovel 10, and the fallen leaves are scooped up by the cleaning plate. The scooped fallen leaves can be further gathered to the middle area of the collecting shovel 10 under the action of the spiral mechanism 12, and the conveying component 20 with one end located in the middle area can convey the fallen leaves to the other end through the conveying part 21, and under the action of gravity, the fallen leaves fall into the collecting bin 30 through the open mouth to complete the collection.
[0051] It is understandable that as the amount of fallen leaves accumulated in the collecting shovel 10 increases, the conveying efficiency of the multiple conveying parts 21 of the conveying device can also be gradually improved, and the fallen leaves and foreign objects accumulated in the collecting shovel 10 are only gathered at the front end of the collecting shovel 10 and will not cause blockage.
[0052] According to the fallen leaves collection device of the embodiment of the present application, the fallen leaves are transported to the collection bin 30 through the collection shovel 10 in cooperation with the conveying device. There is no need to set up a pneumatic system for fallen leaves collection, so there is no need to worry about the problem of pneumatic channel blockage. The mechanical structure realizes fallen leaves collection, with higher cleaning efficiency, better cleaning effect and lower energy consumption.
[0053] See also Figure 3 and Figure 4 As shown, according to some embodiments of the present application, the collecting shovel 10 further includes: a folding door 13, which is rotatably disposed at the left and right ends of the shovel body 11, so that the size of the collecting area of the collecting shovel 10 is adjustable.
[0054] Specifically, when the fallen leaf cleaning device 100 is in the cleaning position, the folding door 13 can be flipped relative to the shovel body 11 to adjust to a suitable opening angle of the folding door 13. The folding doors 13 located at both ends of the shovel body 11 can be close to the curbstones on both sides of the road, and the bottom ends of the folding door 13 and the shovel body 11 can be provided with cleaning plates for cleaning and reducing the wear of the folding door 13 and the shovel body 11.
[0055] In this way, by setting the folding door 13, the collection range of the collecting shovel 10 can be expanded and the collection range of the collecting shovel 10 can be adjusted to adapt to road surfaces of different widths. This can not only improve the efficiency of cleaning and collecting fallen leaves and improve the versatility of the fallen leaf collection device, but also the folding door 13 is set at an angle to the shovel body 11, which can optimize the gathering effect of fallen leaves and further improve the cleaning and collection effects.
[0056] like Figure 4 and Fig.10 As shown, in some embodiments, a limiting plate 111 is provided at the end of the shovel body 11, one end of the limiting plate 111 is pivotally connected to the shovel body 11, a plurality of limiting holes 112 are provided on the limiting plate 111, a limiting portion 131 is provided on the back side of the folding door 13, the limiting portion 131 can be selectively matched with any one of the plurality of limiting holes 112, and the limiting portion 131 can be constructed as a limiting pin.
[0057] Specifically, the side facing forward of the folding door 13 is defined as the front side, and the side facing backward is defined as the back side. A limiting portion 131 is provided on the back side. The end of the shovel body 11 is provided on a limiting plate 111 which cooperates with the limiting portion 131. The limiting plate 111 has a plurality of limiting holes 112. The limiting portion 131 is formed as a limiting pin and cooperates with the limiting hole 112 through a latch to achieve angle limitation of the folding door 13.
[0058] In this way, on the one hand, through the cooperation between the limiting portion 131 and the limiting plate 111, the fixed limiting of the folding door 13 can be achieved, thereby reducing the movement of the folding door 13 during cleaning and improving the cleaning and collection effects. On the other hand, the provision of multiple limiting holes 112 allows the folding door 13 to be locked and limited at a suitable angle relative to the shovel body 11, thereby reducing the difficulty in adjusting the angle of the folding door 13 and improving the fixing stability and reliability of the folding door 13 at a suitable angle.
[0059] It should be pointed out that the cleaning plate body arranged under the folding door 13 is constructed as a flexible plate, and the folding door 13 and the shovel body 11 are constructed as a movable connection structure. During the cleaning process, scraping and sweeping are achieved under the action of gravity, and when passing through obstacles, the folding door 13 and the flexible plate can move upward or downward synchronously to pass through raised obstacles or recessed obstacles, thereby improving passability.
[0060] like Fig. 9 As shown, further, a first cleaning member 40 is provided at the front end of the shovel body 11 , and a second cleaning member 50 is provided at the front end of the folding door 13 .
[0061] That is to say, the fallen leaf cleaning device 100 of the embodiment of the present application can further set a first cleaning component 40 in front of the shovel body 11, such as a front and rear parallel roller brush, and can set a second cleaning component 50 at the front end of the folding door 13, such as: left and right sweeping discs.
[0062] In this way, the fallen leaf cleaning device 100 can be matched with the first cleaning part 40 and the second cleaning part 50 to perform one-stop ground cleaning. Under the premise of lower energy consumption, it can also enrich the functionality of the fallen leaf cleaning device 100, realize the simultaneous cleaning of fallen leaves and cleaning of foreign objects on the ground, improve cleaning efficiency and reduce costs.
[0063] like Figure 5 As shown, according to some embodiments of the present application, the spiral mechanism 12 includes: a first shaft segment 121 and a second shaft segment 122, a first spiral blade 123 arranged along a first rotation direction is arranged in the first shaft segment 121, a second spiral blade 124 arranged along a second rotation direction is arranged in the second shaft segment 122, a third shaft segment 125 corresponding to an intermediate area is formed between the first shaft segment 121 and the second shaft segment 122, and the first spiral blade 123 and the second spiral blade 124 are suitable for gathering fallen leaves to the intermediate area.
[0064] Thus, the first spiral blade 123 and the second spiral blade 124 can respectively realize the fallen leaves collection operation from left to right and from right to left, and can quickly collect the fallen leaves to the middle area to improve the transportation efficiency of the accumulated fallen leaves, thereby improving the cleaning efficiency.
[0065] Exemplarily, the spiral mechanism 12 may include a first shaft segment 121, a second shaft segment 122, and a third shaft segment 125, the first shaft segment 121 is provided with a first spiral blade 123, the second shaft segment 122 is provided with a second spiral blade 124, one end of the first shaft segment 121 is provided with a bearing seat, a sprocket (i.e., a driving wheel 22) is provided on the third shaft segment 125, one end of the second shaft segment 122 is provided with a driving motor, and a sprocket positioning sleeve is provided between the sprocket and the third shaft segment 125, so as to drive the first shaft segment 121, the second shaft segment 122 and the third shaft segment 125 to rotate synchronously through the driving motor.
[0066] like Figure 2As shown, in some embodiments, the conveying assembly 20 includes: a driving wheel 22, a driven wheel 23 and a belt transmission member 24 wound around the driven wheel 23 and the driving wheel 22. The conveying part 21 can be constructed as a scraper and is arranged at equal intervals on the belt transmission member 24. A partition 25 is also provided on the side of the conveying assembly 20 that conveys the fallen leaves toward the collection bin. The partition 25 and the scraper define a plurality of conveying spaces for accommodating the fallen leaves. The driving wheel 22 is dynamically connected to the spiral mechanism 12, or the driving wheel 22 is provided separately.
[0067] Specifically, the belt transmission member 24 can be a transmission chain, a transmission belt, or a belt transmission structure of a transmission belt and a transmission chain. Through meshing or friction with the driving wheel 22 and the driven wheel 23, it drives multiple conveying parts 21 configured as scrapers to move from one end of the transport component to the other end and reciprocate. When the belt transmission member 24 is configured as a transmission belt, the transmission belt and the scraper can define multiple conveying spaces for conveying fallen leaves. In the embodiment in which the belt transmission member is configured as a transmission chain, the transmission structure can be divided into two sides, one side is the fallen leaf conveying side moving from the collecting shovel 10 to the collecting bin 30, and the other side is the fallen leaf conveying side from the collecting bin 30. The scraper moves to the fallen leaf cleaning side of the collecting shovel 10, and the fallen leaves are collected into the conveying space during the process of the scraper moving from the tail end of the fallen leaf cleaning side to the head end of the fallen leaf conveying side, and the fallen leaves are conveyed to the collecting bin 30 during the process of the scraper moving from the tail end of the fallen leaf conveying side to the head end of the fallen leaf cleaning side. That is, when the scraper falls into the collecting shovel 10, at least part of the fallen leaves and foreign objects gathered in the middle area of the collecting shovel 10 can be scraped up, and the blocking effect of the partition 50 can prevent the fallen leaves from being scattered again, and convey them to the collecting bin 30 to realize belt transmission, so as to quickly collect the fallen leaves and foreign objects accumulated in the shovel body 11 into the collecting bin 30, thereby improving the collection efficiency.
[0068] In some embodiments, the driving wheel 22 can be set on the third shaft segment 125 of the spiral mechanism 12 to achieve synchronous movement of the conveying component 20 and the spiral mechanism 12, reduce structural costs, and improve the stability and reliability of the synchronous movement of the conveying component 20 and the spiral mechanism 12. In other embodiments, the driving wheel 22 can be provided with a power source separately, or the power input of the driving wheel 22 is parallel to the power input of the spiral mechanism 12, and the power transmission between the two will not interfere with each other. Although the structure is more complicated, the spiral mechanism 12 and the transport component are independent of each other, and the difficulty of repair and maintenance is lower.
[0069] Exemplarily, the conveying portion 21 can be constructed as a scraper, and the belt transmission member 24 can be constructed as a transmission chain. A driving wheel 22 is arranged on the third shaft segment 125, and a driven wheel 23 is arranged at the other end of the transport component to drive the transmission chain through the third shaft segment 125. There is a certain inclination angle between one end and the other end of the transport component, and the other end is arranged higher than one end, so that fallen leaves and foreign objects can be brought to the other end through multiple scrapers and accumulated in the collection bin 30. The transmission chain can be tensioned by setting a tensioning mechanism.
[0070] like Figure 6 As shown, according to some embodiments of the present application, the collection bin 30 has a switch door 31 , and the switch door 31 is formed on the right side of the collection bin 30 .
[0071] Specifically, the setting of the opening and closing door 31 allows the fallen leaves and foreign objects in the collection bin 30 to be directly packed after they are fully collected, and easy unloading can be achieved through the opening and closing door 31. The packed fallen leaves and foreign objects can be conveniently and quickly placed on the edge of the road from the right side, thereby reducing the frequency of dumping fallen leaves and foreign objects, reducing the difficulty of dumping, and reducing the cost of multiple trips to dump fallen leaves.
[0072] Preferably, the opening and closing door 31 is configured as a folding door, and the lower edge of the opening and closing door 31 is flipped over to open the collecting bin 30 .
[0073] like Figure 7 and Figure 8 As shown, in some embodiments, the fallen leaf cleaning device 100 further includes: a base 60, which can be selectively connected to the vehicle 200, and the base 60 defines a receiving cavity, and the collection bin 30 is disposed in the receiving cavity.
[0074] Therefore, by providing the base 60 , the difficulty of docking the fallen leaf cleaning device 100 with the vehicle 200 can be reduced, and the fallen leaf cleaning device 100 can be formed as an optional accessory of the vehicle 200 , which can improve the adaptability of the fallen leaf cleaning device 100 .
[0075] Combination Figure 7 and Figure 8 As shown, further, the fallen leaf cleaning device 100 also includes: a lifting mechanism, the lifting mechanism includes a first lifting member 71 and a second lifting member 72, one end of the first lifting member 71 is connected to the base 60, and the other end is connected to the collecting shovel 10, one end of the second lifting member 72 is connected to the base 60, and the other end is connected to the other end of the conveying component 20, so that the collecting shovel 10 can be switched between the cleaning position and the storage position, and in the cleaning position, the collecting shovel 10 is lowered to be flush with the ground, and in the storage position, the collecting shovel 10 is spaced apart from the ground.
[0076] Furthermore, the transport component and the collecting shovel 10 are also provided with a box body, which includes a cover of the feeding screw mechanism 12 and a shell of the transport component. The front end of the cover is open for feeding, the screw mechanism 12 is installed on the inner side of the left and right side panels of the cover, and the folding door 13 is installed on the outer side of the left and right side panels of the cover. The driven wheel 23 and the tensioning mechanism are installed on the side panels of the shell, and an inspection port is opened on the top of the shell to inspect the transport component. Driven by the conveying part 21, the fallen leaves move upward at the bottom of the shell, reach the opening at the top of the shell, and then fall into the collection bin 30. The collection bin 30 is fixed on the base 60, and the base 60 is connected to the box body through the first lifting member 71 and the second lifting member 72.
[0077] It should be pointed out that the first lifting member 71, the second lifting member 72, the box body and the cover define a four-bar linkage mechanism, through which the collection shovel 10 of the fallen leaf collection device and the transport component can be synchronously moved, and the cleaning position and the storage position can be easily and conveniently switched, reducing the difficulty of use and transportation.
[0078] Of course, the embodiments of the present application are not limited to realizing the switching between the cleaning position and the storage position through a four-bar linkage mechanism, and can also realize the switching between the cleaning position and the storage position through a triangular mechanism, a sprocket chain drive, a gear rack drive, or even a mechanical structure such as a counterweight pull, and the present application does not make specific limitations. Furthermore, the collection shovel 10 is also provided with a walking mechanism, and the walking mechanism includes: at least three walking wheels 81, and two of the walking wheels 81 are located at the left and right ends of the collection shovel 10.
[0079] It can be understood that the first lifting member 71 and the second lifting member 72 can both be constructed as a hydraulic lifting cylinder structure, and the large and small chambers of the lifting cylinder are connected and floated, so that the fallen leaf collection device can contact the ground under the action of its own weight to achieve cleaning, and the walking mechanism can support the fallen leaf collection device and move under the drive of the vehicle 200. The walking wheels 81 can be three, four or more to improve the passability, and when one or more of the walking wheels 81 fall into a pothole, the other walking wheels 81 and the first lifting member 71 and the second lifting member 72 can support the fallen leaf collection device and achieve smooth obstacle avoidance, that is, adaptive obstacle avoidance is achieved by cooperating with the lifting cylinder and the walking mechanism.
[0080] like Figure 7 and Figure 8 As shown, the present application also proposes a vehicle 200, in which the above-mentioned fallen leaf cleaning device 100 is detachably arranged on the vehicle body, and the technical effect possessed is consistent with the above-mentioned fallen leaf cleaning device 100, which will not be repeated here.
[0081] The other structures and operations of the fallen leaf cleaning device 100 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be repeated here.
