Description

Technical Field

[0001] The present invention relates to the technical field of floor cleaning vehicles, and more specifically, to a floor cleaning sweeper vehicle. Background Art

[0002] There are also many deficiencies in the floor cleaning vehicle technology used on urban streets. Its cleaning area on the ground is narrow, the speed is slow, and it causes wear to the ground. It still cannot meet the requirements for environmental protection and cleaning of urban streets, and there is still a long way to achieve mechanized full operation. The most important thing is that it only cleans but does not recycle and clean, and does not play a cleaning role. Summary of the Invention

[0003] The purpose of the present invention is to realize a floor cleaning sweeper vehicle that uses the wind of a suction fan to suck up ground garbage and dust residues and load them into the carriage, compact them and send them to the landfill, keeping the ground clean and tidy, greatly reducing ground dust pollution and reducing the trouble of smog, playing a major role in urban environmental protection, reducing a large amount of labor for manual cleaning, saving a large amount of cleaning costs. During the operation process, it is equipped with an advanced sensing system and a numerical control system, and has a wide cleaning area, fast speed, and is clean, without wearing the ground. It can clean dust residues on streets, roads, airports, squares, etc., and can solve the problems of cleanliness and environmental protection of cities and roads for a long time.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: including a beam frame, a slag suction port and a motor. At the front end position on the beam frame, a battery box is equipped, and multiple storage batteries are installed in the battery box and connected in series to the motor through a structural connection. The motor is connected to the controller in the cab through a wire tube. The motor uses a first V-belt pulley arranged on the frame shaft, and the first V-belt pulley is opposite to the second V-belt pulley inlaid at the upper end with a suction fan. In the middle and rear parts of the beam frame, a slag storage box is provided. The slag storage box is connected to the suction fan through a pipeline, and the suction fan is connected to a slag blowing pipe and a slag suction port respectively through pipelines.

[0005] The automatic ground environmental protection vehicle of the present invention utilizes the vehicle beam frame. At the front end of the beam frame, a battery box is equipped. Multiple batteries are installed in the battery box and connected in series to drive the motor. The control of the motor is controlled by the automatic controller in the cab for speed and switch. A first V-belt pulley is structured on the motor shaft and is opposite to the second V-belt pulley of the upper suction fan. The V-belt is used to achieve the series connection function. The suction fan is connected to the slag storage box through a pipeline. The slag storage box has the function of receiving the blowing and absorbing of dust by the suction fan.

[0006] Further, the exhaust fan has a shaft sleeve arranged at the middle position of the frame shaft. The shaft sleeve is provided with spiral blades and round steel plates respectively by the frame. The blades are composed of several pieces and are arranged to be embedded in the frame of the round steel plate. The blades are respectively composed of frames in spiral and volute shapes. One side of the blade is arranged on the round steel plate, the opposite side is arranged on the circular steel plate, and the other opposite side is arranged on the shaft sleeve. The blades are composed of frames to form two different shapes and are separated from each other by one structure. The air inlet of the exhaust fan is arranged in the structure of the air duct towards the rear of the vehicle. And a circular steel plate and a small-mouth frame of a conical square basket are structurally combined at the air inlet formed by the frame of the exhaust fan. The large-mouth frame of the conical square basket faces the rear of the vehicle and forms a communicating structure with the air duct. The air outlet of the exhaust fan is discharged outwards from the periphery of the blades, and most of the air is discharged through the filter screen arranged on the filter door, and a small part of the air enters the first slag blowing pipe for cleaning the ground and is discharged out.

[0007] At the position of the motor on the girder frame, there is a steel frame. A exhaust fan is installed on the frame. The air inlet of the exhaust fan faces the rear of the vehicle, and the air outlet outputs air to the periphery and is discharged after filtration. A part of the air is used to blow and remove dust and slag.

[0008] Further, a slag storage box is arranged at the middle and rear part of the girder frame. The front part of the top surface of the slag storage box is empty, and the rear part is closed. A ventilation duct is arranged on the empty front part. In front of the slag storage box is a sliding door composed of a group of hydraulic pumps. The rear seat structure of the hydraulic pump is arranged on the front end of the girder frame. An infrared monitor is arranged in the slag storage box, and the infrared monitor is connected to the machine in the cab through a wire tube.

[0009] A slag storage box is arranged at the middle and rear part of the girder frame. The slag storage box is used to store slag and impurities. In front of the slag storage box is a door pushed by a hydraulic pump. The rear seat of the hydraulic pump is installed on the frontmost frame of the girder. The rear end of the slag storage box is a double-door. When the double-door is closed, it is sealed. After the slag and impurities in the slag storage box are compacted and filled, the double-door is opened when it is sent to the slag yard, and the slag and impurities are pushed out of the box by the hydraulic pump and put into the slag yard.

[0010] Further, a ventilation duct is arranged on the top of the slag storage box, and a screen is arranged in the ventilation duct. The space of the ventilation duct is wide and high. The ventilation duct is formed by a frame to slow down the wind speed. The slag storage box is arranged under the frame of the screen. Filter rooms are arranged on both sides and the top of the exhaust fan. There are multiple filter doors in the filter room. The filter doors are all formed into a structure that can be opened and closed through the frame, and filter screens are arranged on the surface of the filter doors. A small amount of the air outlet of the exhaust fan is used for slag blowing and passes through the square pipe, and most of the air is squeezed out from the filter screen holes of the filter doors.

[0011] The air inlet is set in the middle front part of the top of the slag storage box. A screen is set in the air inlet. When the wind, dust and slag enter the air duct at the same time, the wind and dust pass through the screen holes. The slag cannot pass through the mesh holes and falls into the slag storage box below. There are multiple filter doors on both sides and the top of the exhaust fan. Each filter door can be opened and closed. The filter screen is set on the filter door panel. The wind discharged by the exhaust fan goes out from the filter mesh holes without dust. The dust and sand remain in the filter and fall into the sand storage boxes on both sides below and are sent to the slag yard for treatment. The rear end of the right and left sides of the slag storage box is the air inlet duct. The wind sucked by the exhaust fan and the dust and slag brought by the wind must pass through the air duct to enter the air duct.

[0012] Furthermore, the bottom of the slag storage box has a solid structure at the middle and rear part of the beam frame, and the width of both sides exceeds the beam frame.

[0013] A hydraulic pump is installed between the rear end of the beam frame at the bottom of the slag storage box and the slag suction port. When cleaning the ground slag, the hydraulic pump extends downward to make the brush at the bottom of the slag suction port touch the ground. When not cleaning the ground slag, the hydraulic pump is retracted to make the slag suction port leave the ground.

[0014] Furthermore, the slag suction port is set at the rear lower end of the whole vehicle, and the port faces the center of the front of the vehicle. The port should be higher. The slag suction port is lower in the middle part of the rear, and it rises to the rear and is provided with a wind slot. The top surfaces of the left and right corners behind the slag suction port are each provided with an upper wind port, which is square and communicates with the air inlet pipes on both sides of the rear end of the slag storage box and is combined into a telescopic structure with a hydraulic pump. The edges of the left, right and rear directions of the slag suction port are in contact with the ground and are provided with brushes to stop the dust. The upper structure of the brush has a number of springs, which are connected to the brush on the ground with a frame to stop the dust.

[0015] The slag suction port is set at the rear lower end of the vehicle. The opening of the slag suction port is higher towards the front and lower towards the middle. There is an upper wind port at the left and right corners of the rear. After the dust and slag enter the slag suction port, they enter the air duct from the upper wind port. There is a wind slot between the upper wind ports at the left and right corners, so that the dust and slag in the port have a place to swirl before reaching the upper wind port. The brush is set at the bottom of the left, right and rear three directions of the slag suction port. When the brush is running to clean the dust and slag on the ground, the dust and slag entering the slag suction port are all surrounded. The brush structure has several spring structures on the brush frame rod. There are some uneven places on the ground, and the spring will automatically adjust the brush to balance the ground.

[0016] Furthermore, the bottom of the filter room on the left and right sides of the exhaust fan is vertically downwardly formed with a square tube, and the square tube is provided with a damper switch to control the air volume required to blow away the dust residue on the ground.

[0017] A square tube is constructed vertically downward from the bottom of the filter room on the left and right sides of the exhaust fan at a certain position from the ground, and a damper switch is arranged on each square tube. The function of the damper switch is to control the air volume required for blowing away the dust on the ground.

[0018] Further, on each of the two side pipes of the first slag blowing pipe, the first bent round pipe, the second bent round pipe, the bifurcated pipe and the second slag blowing pipe, a first bent round pipe with a bend is arranged outward. The bending directions are balanced and forward. Then, a second bent round pipe with a 90-degree bend is used for each. The bending directions extend outward. The second bent round pipe is connected to the pipe orifice of the first bent round pipe and is buckled with a steel pipe sleeve by a rubber ring and can rotate 360 degrees. A bifurcated pipe is welded backward and balanced on the second bent round pipe extending outward. On the pipe orifice of the second 90-degree second bent round pipe, a first slag blowing pipe and a second slag blowing pipe with a bend of about 100 degrees are used. The joints of the two second bent round pipes and the second slag blowing pipe are also buckled with a steel pipe sleeve by a rubber ring. The bending directions are forward and can rotate 360 degrees. When the first slag blowing pipe and the second slag blowing pipe blow slag, they are arranged in a relatively front-wide and rear-narrow manner. A spiral steel sheet is arranged in the guiding pipe section. Three air outlets are respectively opened in the middle parts of the first slag blowing pipe and the second slag blowing pipe, and a steel sheet is arranged outside the air outlets to block the air outlet direction, so that the blown air moves the dust and slag on the ground and then concentrates and sucks them into the vehicle.

[0019] Structured first slag blowing pipes extend outward from a certain position above the ground at the outer sides of the lower ends of the two side pipes. First, a 90-degree first bent round pipe is used, and then a 90-degree second bent round pipe is used. They are buckled with a steel pipe sleeve by a rubber ring to enable the joint to rotate. A first bent round pipe and a bifurcated pipe are welded backward and balanced on the second bent round pipe towards the rear of the vehicle. Another structured second slag blowing pipe is arranged on the pipe orifice of the other second bent round pipe. The joint is also buckled with a steel pipe sleeve by a rubber ring. Similarly, the second bent round pipe can rotate. When cleaning and sucking the dust and slag on the ground, the guiding pipe faces forward. When the whole first slag blowing pipe collects the dust and slag, the second slag blowing pipe rotates the guiding pipe backward and collects it with a hydraulic pump and attaches it to the side of the slag storage box. The overall structures of the first slag blowing pipes on both sides are front-wide and rear-narrow. The guiding pipe sections of the second slag blowing pipes extending forward are smaller. A spiral steel sheet is arranged inside the guiding pipe to make the output air form a whirlwind, roll up the dust and slag on the roadside or street side with the wind and move them towards the middle part of the lane. Three air outlets are respectively arranged below the rear of the guiding pipes on both sides. These three air outlets are closer to the middle part one by one, so that the dust and slag gradually move towards the central position with the wind. A steel sheet is structured outside each air outlet to half surround the air outlet, so that the air blows obliquely on the ground to move the dust and slag away. The last air outlet at the rear of the first slag blowing pipes on both sides is an air outlet offset. The direction of the air outlet offset faces the center of the slag suction port at the lower rear part of the vehicle. During operation, the dust and slag moved to the middle part are blown into the slag suction port. Description of the Drawings

Specific implementation manner

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

[0029] The working principle of the present invention is as follows: The present invention mainly adopts a steel structure, uses the vehicle head and the engine, and the girder frame 1 and wheels of the vehicle are equipped with a hydraulic structure. A battery box 4 is equipped at the front end position on the girder frame 1. Multiple batteries are assembled in series in the battery box 4 to drive a DC motor 5. The motor 5 is controlled by an automatic controller in the cab for speed and switch. A first V-belt pulley 9 is structured on the motor 5 shaft. The first V-belt pulley 9 faces the second V-belt pulley 10 of the upper exhaust fan 6, and the exhaust fan 6 is driven by being connected in series with a V-belt.

[0030] The working principle of the present invention is as follows: One end of the footrest of the exhaust fan 6 is structured on the main beam frame 1, and the other end is structured on the slag storage box 14 frame. At the upper end of the frame, a shaft is equipped. At one end of the shaft, a V-belt pulley is structured. It is driven in series by the second V-belt pulley 10 on the shaft of the motor 5. In the middle position of the shaft, a shaft sleeve 7 of the exhaust fan 6 is structured. On the shaft sleeve 7, blades 43 and a round steel plate 45 are structured. The blades 43 are composed of several pieces, half of which are spiral-shaped and the other half are vortex groove-shaped. One side of the spiral-shaped blade 43 is structured on the round steel plate 45, the opposite side is structured on the circular steel plate 2, and on the contrary, one side is structured on the shaft sleeve 7. One side of each vortex groove-shaped blade 43 is structured on the round steel plate 45, and the opposite side is structured on the circular steel plate 2. The two different-shaped blades are each separated by one piece and structured.

[0031] The working principle of the present invention is as follows: The shaft sleeve 7 and the blades 43 are structured by welding, and the shaft sleeve 7 and the shaft are structured by a pin locking structure to avoid damaging the shaft.

[0032] The working principle of the present invention is as follows: The air inlet 12 of the exhaust fan 6 faces the air duct 22 at the rear of the vehicle. At the air inlet 12 section of the shell opening of the exhaust fan 6, a circular steel plate 2 and the small opening of a conical square basket 3 are structured together. The large opening of the conical square basket 3 faces the rear of the vehicle and is structured to communicate with the air duct 22. The air outlet of the exhaust fan 6 is from the periphery of the blades 43. Most of the air goes out through the filter screen 20 on the filter door 19, and a small amount enters the first slag blowing pipe 31 and the second slag blowing pipe 37 for cleaning the ground and goes out.

[0033] The working principle of the present invention is as follows: The slag storage box 14 is arranged at the middle and rear part of the main beam frame 1. The purpose is to store the slag and impurities absorbed from the ground in the slag storage box 14. The front part of the top surface of the slag storage box 14 is empty, and the rear part is closed. A ventilation duct 22 is arranged above the empty front part. In front of the slag storage box 14 is a door pushed and pulled by a hydraulic pump 16. The rear seat of the hydraulic pump 16 is structured on the front end of the main beam frame 1. An infrared monitor is arranged in the slag storage box 14. In the cab, it can be observed that when the slag and impurities in the front part of the slag storage box 14 are full, the hydraulic pump 16 is started to push backward and press tightly, then the front part is emptied. The hydraulic pump 16 is retracted and then loaded and pressed again until it is full or when getting off work and sent to the slag unloading site, the rear box door is opened, and the hydraulic pump 16 is extended to push the slag and impurities in the slag storage box 14 out. At the rear end of the slag storage box 14, a double-door is arranged. When sucking the ground dust and slag, the door is closed and sealed, and the door is only opened for unloading slag when the slag is sent to the slag yard. Then, the slag storage box 14 is cleaned with water, and at the same time, the filter room, the filter door 19, and the filter screen 20 are cleaned. A screen 18 is arranged in the ventilation duct 22 on the top of the slag storage box 14. After the dust and slag rise from the rear air inlet pipe 21 at the same time, the space of the ventilation duct 22 is wide and high, the wind speed slows down, the slag and impurities are blocked by the screen 18 and fall into the slag storage box 14 below, and the dust passes through the holes of the screen 18 and enters the exhaust fan 6.

[0034] The working principle of the present invention is: filter rooms are arranged on both sides and the top of the exhaust fan 6, and filter doors 19 are arranged in the filter rooms. Each filter door 19 can be opened and closed, and the face of the filter door 19 is provided with a filter screen 20. The top and front of the filter rooms on both sides can be connected. A ventilation square tube 29 extends vertically downward from the bottom of the filter rooms on both sides of the exhaust fan 6. A small amount of wind used for blowing slag must pass through the square tube 29 when the exhaust fan 6 is used. Most of the wind is squeezed out from the holes of the filter screen 20 of the filter door 19, and the dust falls into the sand storage box 15 under the door 19 and is sent to the slag unloading site for treatment.

[0035] The working principle of the present invention is: the rear end of the left and right sides of the slag storage box 14 has an air inlet pipe 21, the upper end of the air inlet pipe 21 is connected with the wind slot 27, and the lower part is connected with the slag suction port 24. The function of the air inlet pipe 21 is to transport the dust and slag from the slag suction port 24 to the upper part together with the dust and slag. The bottom of the slag storage box 14 is firmly structured in the middle and rear part of the beam frame 1, and the width of both sides exceeds the rear end of the beam frame 1 of the vehicle and the slag suction port 24, and is connected with a hydraulic pump 26. The purpose is to extend the hydraulic pump 26 when cleaning the dust and slag on the ground, and the brush 25 on the side of the slag suction port 24 at the lower end of the rear of the vehicle can touch the ground to work. When the dust on the ground is not being sucked, the hydraulic pump 26 contracts, and the suction port 24 is separated from the ground. The suction port 24 is set at the rear lower end of the vehicle, and the opening faces the center of the front of the vehicle. The opening should be higher so that all the dust blown from the front can enter it. The suction port 24 is lower in the middle part of the rear, and it rises at the rear and is provided with a wind slot 27, so that the dust has room to turn when it enters the back. There is a square upper wind port 26 on the top surface of the left and right corners behind the suction port 24, which is connected to the air inlet pipe 21 on both sides of the rear end of the slag storage box 14 and is combined with the hydraulic pump 26 to form a telescopic movable structure. When running, the dust goes from the upper wind port 26 to the air inlet pipe 21 with the wind.

[0036] The working principle of the present invention is: the edges of the left, right and rear directions of the slag suction port 24 are in contact with the ground and brushes 25 are set to stop the dust. The upper structure of the brush 25 has a plurality of springs 28. Regardless of whether the ground is flat or uneven, the springs 28 will automatically adjust to make the brush 25 touch the ground to stop the dust. When cleaning the dust on the ground, the air volume sucked by the exhaust fan 6 from the slag suction port 24 exceeds the natural air volume in front of the slag suction port 24 at the driving speed. The excess wind comes from the wind sent in by the wind outlet 42 of the first slag blowing pipe 31 and the air around the slag suction port 24, so that the dust floating in the space around the slag suction port 24 is brought into the slag suction port 24 by the wind.

[0037] The working principle of the present invention is as follows: At the bottom of the filtration chambers on the left and right sides of the exhaust fan 6, a square pipe 29 is vertically extended downward for each side. A damper switch 30 is provided on the square pipe 29. The function of the switch 30 is to control the air volume required for blowing and moving the dust and slag on the ground. If the air volume is too large, the dust and slag are easily blown up and float everywhere; if the air volume is too small, the dust and slag cannot be moved to the optimal position. Therefore, the function of the switch 30 is very important.

[0038] The working principle of the present invention is as follows: The first slag blowing pipe 31, the first bent round pipe 32, the second bent round pipe 33, the bifurcated pipe 35, and the second slag blowing pipe 37 for cleaning and sucking ground dust and slag are each provided with a first bent round pipe 32 with a 90-degree bend extending outward from the square pipes 29 vertically downward on both sides. The bending directions are balanced and forward. Then, each is further provided with a second bent round pipe 33 with a 90-degree bend, and the bending direction extends outward. The pipe orifice structure of the first bent round pipe 32 is buckled with a rubber ring and a steel pipe sleeve 34 and can rotate 360 degrees. A bifurcated pipe 35 is welded in a balanced manner toward the rear on the second bent round pipe 33 extending outward. On the pipe orifice of the second 90-degree second bent round pipe 33, a second slag blowing pipe 37 with a bend of about 100 degrees is further provided. The joint of the two pipes, the second bent round pipe 33 and the second slag blowing pipe 37, is also buckled with a rubber ring and a steel pipe sleeve 36. The direction of the bent guiding orifice 38 is forward and can rotate 360 degrees. When the first slag blowing pipes 31 and the second slag blowing pipes 37 on both sides blow slag, they are arranged relatively with the front wide and the rear narrow. The purpose is to generate wind from the front to move the dust and slag to the central part at the back, and finally send the dust and slag into the slag suction port 24. The first slag blowing pipes 31 and the second slag blowing pipes 37 extending forward on both sides are provided with a spiral steel sheet 40 structure in the guiding orifice 38 section of the pipe orifice, so that the wind blowing on both sides at the very front becomes a cyclone and spins the dust and slag on both sides into the central position. Three air outlets 41 are respectively opened in the middle parts of the first slag blowing pipes 31 and the second slag blowing pipes 37 on both sides. A steel sheet is arranged outside each air outlet 41 to block the direction of the blown air, so that the blown air blows obliquely on the ground to move the dust and slag away. The last air outlet 42 in the backward direction on both sides forms an air outlet offset 42, and the air outlet direction is toward the center of the slag suction port 24 at the lower part behind the vehicle. During operation, the wind from the air outlet offset 42 sends the dust and slag moved to the middle part in front into the slag suction port 24. The first slag blowing pipes 31 and the second slag blowing pipes 37 extending forward on both sides are supported by a 90-degree lifting rod 8 under the pipes. The other end of the lifting rod is welded to another first slag blowing pipe 31 at the back, so that the first slag blowing pipes 31 and the second slag blowing pipes 37 in the front can operate stably. The first slag blowing pipes 31, the first bent round pipes 32, the second bent round pipes 33, the bifurcated pipes 35, and the second slag blowing pipes 37 on both sides are contracted and expanded using a hydraulic pump 16. The rear seat structure of the hydraulic pump is on the beam frame 1, and the fulcrum structure is on the second bent round pipes 33 extending outward. When contracting, first turn the pipes, the first slag blowing pipes 31 and the second slag blowing pipes 37 facing forward, toward the rear, and then retract the extended pipes, the first slag blowing pipes 31, the first bent round pipes 32, the second bent round pipes 33, the bifurcated pipes 35, and the second slag blowing pipes 37, and make them stick to the slag storage box 14. When cleaning and sucking ground dust and slag, first start the hydraulic pump 16 to extend the pipes, the first slag blowing pipes 31, the first bent round pipes 32, the second bent round pipes 33, the bifurcated pipes 35, and the second slag blowing pipes 37, to a certain position above the ground, and turn the pipes, the first slag blowing pipes 31 and the second slag blowing pipes 37 that should face forward, and place them on the lifting rod.
