[0060] Combine the following Figures 1 to 10 , an implementation mode of the present invention is described.

[0061] like Figure 1 , Figure 2 As shown, it is an energy-saving intelligent sweeper, including an intelligent control system, a main sweeping device 1, a collecting device 2 for collecting the swept objects, a garbage lifting and introducing device 3 for introducing the garbage swept by the main sweeping device 1 into the collecting device 2, a disc sweeping device 4, and an intercepting device 5; the disc sweeping device 4 is located on both sides of the vehicle body to guide the swept garbage to the inner side of the vehicle body; the intercepting device 5 is located at the lower part of the vehicle body to intercept the swept garbage; the main sweeping device 1, the collecting device 2, the garbage lifting and introducing device 3, the disc sweeping device 4, and the intercepting device 5 are controlled by the intelligent control system. Different from other sweepers with rolling sweeping as the main sweeping method, the sweeper of the present invention is provided with an intercepting device 5, and the intercepting device 5 is intelligently controlled to improve the sweeping effect.

[0062] Combine the following Figures 5 to 7 The main scanning device 1 of the present invention will be described.

[0063] The main sweeping device 1 includes a rotating main shaft 11, on which a sweeping brush is installed, and the sweeping brush device 12 is retractable; when extended, it is in the working state. In order to realize the retraction of the sweeping brush device 12, the rotating main shaft 11 has multiple groups of sweeping brush devices 12 distributed in rows along the axial direction, and the sweeping rod 121 is connected to the rotating main shaft 11, and the end of the sweeping rod 121 has bristles 122; the rotating main shaft 11 has a driving shaft for driving all the sweeping rods 121 at the same time. The rotating main shaft 11 is controlled by the main shaft motor; the driving shaft is controlled by the driving shaft motor. That is, the main shaft motor drives the rotating main shaft 11 to rotate to achieve cleaning, and the driving shaft motor drives the driving main shaft to rotate, so that the sweeping rod 121 can be retracted.

[0064] The driving shaft is a gear shaft 13, and the surface of the sweep rod 121 that contacts the driving shaft is a rack 14. The rack 14 meshes with the teeth of the gear shaft 13, so that when the driving shaft rotates, multiple sweep rods 121 move simultaneously. In the figure, the gear shaft 13 uses flat teeth, and the rack 14 also uses flat teeth. In the specific implementation process, other teeth can be replaced as needed. There are various styles of gear shafts 13 that can be selected, such as using different gear shafts 13 such as spline shafts and screw shafts. At the same time, the rack 14 also uses different tooth shapes to match the gear shaft 13, so that the rack 14 can be driven when the screw shaft rotates.

[0065] The rotating main shaft 11 is provided with a guide tube 15 for the sweeping rod 121 to pass through, and is used to guide the direction of the sweeping rod 121 to extend and retract. The guide tubes 15 are grouped in pairs, and the guide tubes 15 in the same group are symmetrically arranged on both sides of the driving shaft, which can ensure that the sweeping rods 121 are symmetrically distributed on both sides of the driving shaft. There are at least two sweeping rods 121, which are respectively located on both sides of the sweeping brush device 12 to support the two ends of the sweeping brush device 12 and maintain the stability of the sweeping brush device 12.

[0066] The sweeping brush devices 12 are at least six groups, which are evenly distributed, so as to reduce the angle between each group of sweeping brush devices 12, and reduce the time that the bristles 122 cannot act on the ground when the rotating main shaft 11 rotates. The more sweeping brush devices 12 there are, the closer the main sweeping device 1 is to a cylinder. If the spacing between the sweeping brush devices 12 is large, in order to reduce the time that the bristles 1222 cannot act on the ground, it is necessary to increase the rotation speed of the rotating main shaft 11, or extend the sweeping brush devices 12 longer, but these methods are not necessary when the density of the sweeping brush devices 12 is large enough.

[0067] The positions of the rotating main shaft 11 and the frame 9 are relatively fixed; the main sweeping device 1 also includes a sweeping brush device length detection device 16. The contact area and contact force between the bristles 122 and the ground are adjusted by extending and retracting the sweeping brush device 12. By detecting and ensuring the length of the sweeping brush device 12, the bristles 122 are compensated in the continuous wear and tear, so that the contact area and contact force with the ground are kept stable.

[0068] The driving shaft power mechanism 17 includes a reduction motor 171 connected to the driving shaft and a conductive slip ring 172. The reduction motor 171 rotates synchronously with the rotating main shaft 11. The conductive slip ring 172 supplies power to the reduction motor 171 and controls the operation and stop of the reduction motor 171. The rotating main shaft 11 includes a cylinder 111 and a motor housing 112. The driving shaft is in the cylinder 111, and the reduction motor 171 is in the motor housing 112. The motor housing 112 and the cylinder 111 are connected by a flange, and the reduction motor 171 rotates synchronously with the rotating main shaft 11. When the conductive slip ring 172 supplies power to the reduction motor 171, the reduction motor 171 controls the rotation of the driving shaft, thereby extending and retracting the sweeping rod 121.

[0069] The sweeping brush length detection device 16 is a position detection sensor, which is fixed on the vehicle frame 9, and the position sensor is directly above the rotating spindle 11. As shown in the figure, a through-beam infrared sensor is adopted. When the sweeper is started, the rotating spindle 11 starts to run, and the sweeping brush device 12 extends. The through-beam infrared sensor can sense the signal of the sweeping brush device 12, and the reduction motor 171 stops working. Once the signal is not received, it means that the sweeping brush device 12 has been worn. The distance between the through-beam infrared sensor and the rotating spindle 11 is longer than the distance between the rotating spindle 11 and the ground. The listed through-beam infrared sensor can also be replaced by other sensors with position detection function.

[0070] When the sweeper is running at high speed and is not in the cleaning state, the sweeping rod 121 is retracted and the sweeping brush device 12 is off the ground; when the cleaning operation starts, the rotating main shaft 11 runs, and the gear shaft 13 starts to rotate, and the sweeping brush device 12 extends. The infrared counter-radiation sensor senses the signal of the sweeping brush device 12. When the signal is sensed, the gear shaft 13 stops rotating, and the sweeping brush device 12 stops extending further and starts cleaning. When the bristles are worn, the sweeping rod 121 automatically extends to the point where the sweeping brush length detection device 16 can sense it; once the sweeping rod 121 is extended to the limit and still cannot sense the sweeping brush device 12, the sweeping brush device 12 needs to be replaced.

[0071] With the intelligent control system, the rotation speed of the rotating spindle 11 can be controlled to be adjustable. In addition, the wear of the bristles 122 can be detected and adjusted in time.

[0072] Combine the following Figures 1 to 4 The garbage lifting and introducing device 3 of the present invention will be described.

[0073] The garbage lifting and introducing device 3 includes a guide plate 31 and a garbage lifting and conveying mechanism. The retaining edge is located on both sides of the middle plate 32. The guide plate 31 connects the main sweeping device and the garbage lifting and conveying mechanism. The garbage lifting and conveying mechanism includes the middle plate 32, a plurality of alternately arranged carrier plates 33, a chain 34 driving the carrier plates 33, and a rotating bucket 35. The edges of the carrier plates 33 are tightly attached to the surface of the middle plate 32 and circulate in the rotating bucket 35. In order to allow the swept garbage to enter the rotating bucket 35, the feed port of the rotating bucket 35 is connected to the upper end of the guide plate 31. After the swept garbage passes through the guide plate 31 and reaches the feed port above the rotating bucket 35, it enters the rotating bucket 35 due to gravity.

[0074] The intermediate plate 32 can be set into multiple sections or more complex shapes as required. The chain 34 includes an upper sprocket 341, a lower sprocket 342 and a sprocket positioning device, and the upper sprocket 341 and the lower sprocket 342 are used to drive the chain 34. The sprocket positioning device is located at the position where the intermediate plate 32 turns between the upper sprocket 341 and the lower sprocket 342, and is used to control the trajectory of the chain 34 so that the edge of the loading plate 33 is closely attached to the surface of the intermediate plate 32 and the inside of the rotating bucket 35. The chain 34 moves toward the collecting device 2 on the side where the whole is located at the upper part, that is, the loading plate 33 is loaded with garbage at the position located at the upper part of the intermediate plate 32 and moves to the garbage bin, that is, the loading plate 33 will load garbage when it is located at the upper part, and must be closely attached to the surface of the intermediate plate 32 and the inner surface of the rotating bucket 35 at these positions, thereby completing the loading of garbage. The first positioning sprocket 343 and / or the second positioning sprocket 344 can be provided with a tensioning function, for example, a tensioning adjustment bolt can be provided on the second positioning sprocket 344, and the position of the second positioning sprocket 344 can be fine-tuned by adjusting the tensioning adjustment bolt to control the tension of the chain 34. The second positioning sprocket 344 is located on the side where the chain 34 is located as a whole at the bottom, so when adjusted, the position of the chain 34 as a whole at the bottom is affected, while the garbage is loaded on the upper side, so adjusting the second positioning sprocket 344 will not affect the loading and transportation of the garbage.

[0075] The loading plate 33 includes a rigid plate body and a flexible edge. The rigid plate body can be made of stainless steel to increase the load-bearing capacity of the loading plate 33, and the flexible edge can be made of wear-resistant rubber to reduce the possibility of falling from the gap during lifting.

[0076] The inner surface of the rotating bucket 35 includes a semi-cylindrical fitting portion, which fits with the edge of the carrier plate 33 when the carrier plate 33 moves.

[0077] The guide plate 31 is liftable. In order for the guide plate 31 to guide materials, its bottom must be close to touching the ground, which will hinder the cleaning of larger garbage. When the guide plate 31 is liftable, when the guide plate 31 rises, the main sweeping device 1 can sweep larger garbage. When the guide plate 31 falls again, the larger garbage can be swept onto the guide plate 31. In specific use, the guide plate 31 can be set to be lifted and lowered indirectly. The solution that allows the guide plate 31 to be lifted and lowered intermittently is easy to implement.

[0078] When the sweeper starts and begins to sweep, the garbage swept by the main sweeping device 1 will enter the rotating bucket 35 through the guide plate 31. Since the inner surface of the rotating bucket 35 includes a semi-cylindrical fitting portion, and fits with the edge of the carrier plate 33 when the carrier plate 33 moves. When the rotating bucket 35 passes through the rotating bucket 35, the garbage in the rotating bucket 35 will be carried on the carrier plate 33. When the carrier plate 33 leaves the rotating bucket 35, due to the angle setting of the carrier plate 33 and the middle plate 32, the garbage on the surface of the carrier plate 33 will fall close to the middle plate 32 due to its own gravity, and after passing through the middle plate, it will fall into the garbage bin. In the process of lifting garbage, even if a small amount of garbage falls, it will fall directly into the rotating bucket 35, and the loading plate 33 that passes through the rotating bucket 35 will complete the lifting of the garbage in the hopper.

[0079] In conjunction with the intelligent control system, the lifting frequency, lifting height, and lifting speed of the guide plate 31 can be controlled, so that it is easier to clean the road surface with different garbage and guide all garbage.

[0080] Next, combine Figure 8 , Fig. 9 The interception device 5 of the present invention will be described.

[0081] The interception device 5 is located on both sides of the vehicle frame 9, including a left baffle 51 and a right baffle 52; the left baffle 51 and the right baffle 52 are located behind the disc sweeping device 4, on both sides of the rolling sweeping device and the collecting device 2. The left baffle 51 and the right baffle 52 are symmetrical on both sides of the vehicle body. It also includes a roller brush 53 device located at the rear of the rolling sweeping device; the roller brush 53 device includes a roller brush 53 and a roller brush shell 54. The roller brush 53 is used to intercept the garbage missed at the rear of the sweeper. The upper part of the roller brush shell 54 has a roller brush shell cover, which is convenient for opening the roller brush shell cover to check or repair the roller brush 53. The roller brush 53 is connected with the rolling sweeping device. The so-called connection means that the roller brush 53 can transfer the garbage under it to the bottom of the rolling sweeping device by throwing, sweeping, etc., thereby completing the connection of garbage cleaning, and further improving the cleaning effect.

[0082] When the road sweeper is used, when the vehicle is moving, the lifting device 55 causes the left baffle 51, the right baffle 52, and the roller brush 53 to be lifted synchronously. During the cleaning operation, the lifting device 55 causes the left baffle 51, the right baffle 52, and the roller brush 53 to be lowered synchronously, and the left baffle 51 and the right baffle 52 are lowered to a position close to the ground. The two sides of the roller sweeping device are intercepted by the left baffle 51 and the right baffle 52, and the garbage missed by the roller sweeping device is transferred to the bottom of the roller sweeping device by the roller brush 53, thereby further improving the cleaning effect.

[0083] With the help of the intelligent control system, the lifting and lowering of the interception device 5 as a whole and the transfer of the missed garbage behind the vehicle body by the roller brush 53 can be controlled, thereby improving the cleaning effect.

[0084] The disc sweeper 4 comprises front disc sweepers 41 at both sides of the front part of the vehicle body and rear disc sweepers 42 at both sides of the middle part of the vehicle body. Figures 11 to 13 The front disc sweep 41 is described as follows:

[0085] The front disc sweeper 41 includes a front sweep telescopic device 411, a front sweep elastic device 412, and a front sweep disc 418; one end of the front sweep telescopic device 411 is hinged on the frame 9, and the other end is connected to the front sweep disc 418; one end of the front sweep elastic device 412 is hinged on the frame 9, and the other end is connected to the front sweep telescopic device 411; the front sweep telescopic device 411 and the front sweep elastic device 412 work together to control the telescopic and lifting of the front sweep disc 418; when the front sweep telescopic device 411 is extended, the front sweep disc 418 is located in a low position, and when the front sweep telescopic device 411 is retracted, the front sweep disc 418 is located in a high position. The front sweep elastic device 412 comprises a sleeve 414, a front sweep spring 413, a spring cover 415, and a push rod 416. The front sweep spring 413 is connected in series to the sleeve 414, and the push rod 416 passes through the spring cover 415 and is connected in series to the sleeve 414. An adjustable spring limiter is provided on the sleeve 414. The spring limiter is a front sweep adjusting nut 417 threadedly connected to the sleeve 414. The wedge block 419 is located at the extended end 4111 of the front sweep telescopic device 411, and is telescopically extended along with the extended end 4111. When the wedge block 419 is retracted, it contacts the front sweep elastic device 412, thereby raising the sweeping plate.

[0086] When the front sweep telescopic device 411 is retracted, the wedge block 419 gradually presses against the spring cover 415. As the front sweep disc 418 is further retracted, the center of gravity falls on the spring cover 415. After further retraction, the sweep disc 429 is lifted, and the push rod 416 slides up in the sleeve 414. Under the joint action of the spring and the front sweep telescopic device 411, the front sweep disc 418 is lifted off the ground. When working, when the front sweep telescopic device 411 is extended, the wedge block 419 leaves the elastic device. Due to the self-weight of the front sweep disc 418, the front sweep disc 418 will droop and fall to a low position. At this time, the push rod 416 is retracted to slide down in the sleeve 414, and part of the weight of the sweep disc will fall on the front sweep elastic device 412. By fine-tuning the elastic device through the front sweep adjustment nut 417, the pressure of the front sweep disc 418 on the ground when it falls can be controlled. When the vehicle load increases or decreases, the ground is uneven or other complex road conditions occur, the front sweeping disc 418 can float up and down within a certain range due to the elastic device, thereby maintaining the force on the ground and achieving a satisfactory cleaning effect.

[0087] Combine the following Figure 12 to Figure 14 The rear disc sweep 42 is described as follows:

[0088] The rear disc sweeper 42 comprises a rear sweep telescopic device 421, a four-bar linkage 424, a sweeping disc rod 425, a rear sweep elastic device, and a rear sweeping disc 429; one end of the rear sweep telescopic device 421 is hinged on the vehicle frame 9, and the other end is connected to the sweeping disc rod 425; one end of the four-bar linkage 424 is hinged on the vehicle frame 9, the four-bar linkage 424 and the rear sweeping disc 429 rod 425 are mutually hinged, and the sweeping disc rod 425 is connected to the rear sweeping disc 429 universal ball; there is a rear sweep elastic device between the rear sweep telescopic device 421 and the rod-shaped connecting mechanism; the telescopic movement of the rear sweep telescopic device 421 controls the lifting and lowering of the rear sweeping disc 429; when the rear sweep telescopic device 421 is extended, the rear sweeping disc 429 is located at a high position, and when the rear sweep telescopic device 421 is retracted, the rear sweeping disc 429 is located at a low position. By using the four-bar linkage 424, the relative angles between the sweeping disc rod 425 and the rear sweeping disc 429 and the ground can be kept constant during the lifting and lowering process.

[0089] The extended end of the rear sweep telescopic device 421 is a support rod 422, the support rod 422 is connected with a support sleeve 423, the support sleeve 423 is connected with a rear sweep spring 426, the support sleeve 423 is hinged with the sweep plate rod 425, and the support sleeve 423 and / or the support rod 422 have threads for connecting with the rear sweep adjustment nut 428, which is used to limit the telescopic position of the rear sweep spring 426. Fig.17As shown, the adjusting nut is connected to the support sleeve 423, and can also be installed on the support rod 422 in the same way, which will not be described in detail here. Under the action of the spring, the support rod 422 reciprocates in the support sleeve 423. The elastic force of the rear sweep spring 426 will affect the pressure of the rear sweep disc 429 on the ground. Therefore, when it is necessary to adjust the pressure of the rear sweep disc 429 on the ground, the pressure of the rear sweep disc 429 on the ground can be fine-tuned by adjusting the rear sweep adjusting nut 428.

[0090] When the vehicle load increases or decreases, the ground is uneven, or the bristles of the rear sweeping disc 429 are worn and deformed, the rear sweeping disc 429 can float freely up and down within a certain range to maintain the force of the bristles on the ground and achieve the desired cleaning effect.

[0091] like Figure 1 , Figure 2 As shown, the position of the garbage bin is located at the rear of the vehicle, and the material inlet of the bin is located at the side of the bin, facing the middle plate 32. In order to facilitate dumping, the garbage bin has a bin outlet at the rear of the vehicle, and can be tilted obliquely to the rear. The garbage bin has a rotating fulcrum fixed to the body of the sweeper, and also includes a dumping push rod 21 connecting the body of the sweeper and the bin. The dumping push rod 21 is retracted to make the bin rotate around the rotating fulcrum as the axis, thereby realizing the dumping of the bin.

[0092] like Figure 1 As shown, it also includes a spray device, which includes a front spray device 61 located at the front of the vehicle body for spraying near the ground and an aerial spray device 62 for spraying into the air.

[0093] like Fig.10 As shown, two front wheels and two rear wheels are fixed on the chassis 7 of the sweeper, and there is no shaft connection between the two rear wheels. The front wheels use a steering axle and leaf spring shock absorption; the rear wheels use drag spring shock absorption.

[0094] In summary, the main sweeping device 1, the collecting device 2, the garbage lifting and introducing device 3, the disk sweeping device 4, the intercepting device 5, the spraying device, etc. of the present invention are all controlled by the intelligent control system, so that various cleaning modes can be switched on different road surfaces, thereby improving the cleaning effect.

[0095] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
