Vacuum cleaner module

Abstract

A cleaning machine module is disclosed. This system is a suction device for road surface cleaning coupled to a vehicle, and includes a spraying member for increasing the air volume, a dust pan that uses a hoist to move the suction device close to the road surface, guides the FO to be suctioned, and controls the distance from the road surface, a transfer device using vacuum, an FO sensor for controlling the transfer device, a controller, and a loading box.

Description

Technical Field

[0001] The present disclosure relates to a suction device for a sweeper module that sweeps a road surface.

Background Art

[0002] A road sweeper extracts the air in a dust loading box with a turbo fan to create a vacuum negative pressure, lowers a suction pipe to the road surface, and draws up and removes the dust on the road surface to the dust loading box. When the components of the road sweeper interfere with the vehicle structure, the suction pipe tilts and becomes longer, causing the problem that the sucked FO (foreign object) falls again. The suction port of the suction device is raised to prevent interference with the road surface during vehicle movement or lowered during sweeping operations, so a flexible bellows pipe is used as the suction pipe. This bellows pipe has a suction resistance due to internal unevenness, and there are problems such as the sucked FO during sweeping operations not being able to reach the dust loading box mounted on the upper part of the vehicle body due to the insufficient suction capacity of the road sweeper, or falling back to the road surface again after the operation of the device is interrupted after getting caught in the bellows pipe used as the suction pipe.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present disclosure is to provide a technical solution for solving the insufficient suction capacity of a road sweeper.

[0004] Another object of the present disclosure is to provide a technical solution that can solve the problem of FO leakage in the device.

Means for Solving the Problems

[0005] To achieve the above object, according to one aspect of the present invention, there is a frame for supporting a workpiece, a slide frame having a hoist cylinder capable of injecting a suction device behind a vehicle loading box and lowering it, a sensor for measuring the distance from the road surface, a controller for controlling to maintain a gap from the road surface, a dustpan drive cylinder, a dustpan drive rod, a dustpan, a transfer device disposed between a suction port passage and a first loading box, a transfer device that rotates by a worm and worm gear when a transfer device drive motor is driven, a tone wheel and a sensor disposed on one side of a transfer device drive shaft, and a controller that controls to operate a transfer device drive motor according to necessary control, and when the tone wheel deviates from a stop position, to rotate until the sensor reaches the next stop position and then stop. The inlet is a transfer device disposed on the side, the outlet is disposed on the upper side, a vacuum generated by the air discharge of a turbo fan is maintained, and when the transfer device is opened by the controller, the FO accumulated at the first loading box inlet is sucked by a method of sweeping it into the first loading box with the vacuum formed in the first loading box and the upper side of the transfer device rotating forward. A suction device including a first loading box, a shroud that generates a vacuum in the first loading box and at the suction port with a turbo fan, draws in discarded air and surrounding air to amplify the air volume, injects it at a target point on the road surface to guide the scattered FO to the suction port of the suction device and move it along the inclination of the dustpan to the inlet of the transfer device. An injection member is included. When the vehicle moves, the injection member is lifted to reduce interference during vehicle movement, and the FO is separated through the suction port during suction via a swing arm that lowers the injection member near the road surface during operation. The light FO is filtered by the filter of the loading box, and the FO remaining at the first loading box inlet is removed by moving to the first loading box by the operation of the transfer device.

Advantages of the Invention

[0006] According to what has been disclosed, there is an effect that the FO suction capacity is improved through a transfer device that controls the gap between the injection member that moves at a low height, the suction device, and the road surface, a dustpan that serves as a guide during suction, a first loading box that stores vacuum pressure, and periodically transfers FO to the first loading box in which vacuum is stored. In particular, when the operation is interrupted, the dustpan closes the suction port and there is no leakage of FO.

Embodiments for Carrying Out the Invention

[0008] The aspects of the present invention described above and additional aspects will become even clearer from the embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail so that an ordinary technician can easily understand and reproduce it through such embodiments.

[0009] The hoist 100 according to an embodiment of FIGS. 1 to 3 includes a pair of frames 110 fixed to the loading box of the vehicle, a pair of slide frames 120 coupled to the frames 110 and movable back and forth, and a pair of hoist cylinders 130 coupled to the slide frames 120. The suction device 200 can be ejected rearward of the vehicle by the slide frames 120 and lowered by the hoist cylinders 130. When the vehicle moves, the hoist 100 can place the suction device 200 on the vehicle and fix it to the loading box, and lower the suction device 200 to a low height during work.

[0010] The FO to be sucked immediately moves to the filter 30 of the loading box through the suction port 221D.

[0011] As shown in FIGS. 2, 4, or 7 to 11, if the weight of the FO221C is heavy during suction, it stays at the first loading box inlet 221A, but the transfer device 240 acts to sweep the FO221C gathered at the first loading box inlet 221A to the first loading box 220 side while rotating forward on the upper side during operation.

[0012] The first storage box 220 is arranged in parallel with the suction port 221D, and a vacuum is acting due to the air discharge of the turbo fan 20. When the controller 10 drives the transfer device drive motor 241 for control purposes for the closed transfer device 240, the worm and worm gear 230 rotates the transfer device drive shaft 240A. When the tone wheel 251 connected to the transfer device drive shaft 240A deviates from the stop position, the controller 10 controls to rotate the worm and worm gear 230 until the sensor 250 senses that the tone wheel 251 has reached the next stop position and then stop. As a result, the transfer device 240 releases the vacuum stored in the first storage box 220, and the upper side of the rotary gate type transfer device 240 rotates forward, sweeping the lower side of the transfer device toward the first storage box 220 side, thereby removing the FO221C gathered at the first storage box inlet 221A.

[0013] Through such an operation, the cleaning module according to an embodiment removes the FO221C from the suction port 221D. As shown in FIG. 6, when stopped, the dust pan 210 moves to the closed position, so that the leakage of the FO221C can be doubly prevented.

[0014] This will be elaborated with reference to the DIAGRAM in FIG. 7. An air flow is created from the turbo fan 20 to the injection member 320. If there is FO on the road surface by adding the air volume of the air flow 310B generated from the injection member 320 and the air flow 310C generated in the traveling direction in which the vehicle travels, the FO is pushed into the suction port 221D through the inclination of the dust pan 210. The light FO without suction problems is filtered by the loading box filter 30 through the suction port 221D. As shown in FIG. 9, if the FO221C is heavy and does not pass through the suction port 221D, according to the inertia of the FO221C being sucked and the traveling speed of the vehicle, it catches on the groove at the first storage box inlet 221A. Since a vacuum is being formed while extracting the air from the turbo fan to the first storage box 220, when the transfer device is periodically opened and closed as shown in FIGS. 10 and 11, the heavy FO221C caught on the groove at the first storage box inlet 221A moves to the first storage box 220 and is removed.

[0015] As shown in FIG. 4 or FIG. 12, the suction device 200 can have a sensor in the shape of a grid (GRID FACE) composed of a laser, infrared rays, etc., which has a receiving unit 252 and a transmitting unit 253 for sensing FO. The path through which light rays such as lasers and infrared rays pass is called a detection unit. The FO passing through the detection unit 254 in FIG. 4 blocks the light emitted from the transmitting unit 253 and changes the state of the receiving unit 252. When the FO passes through the detection unit 254, it can logically change a state of 0 to 1, or change a state of 1 to 0 and calculate its value. Therefore, the receiving unit 252, the transmitting unit 653, and the detection unit 254 can be collectively referred to as an FO sensor. However, since the value directly applied to the calculation is the value changed by the receiving unit 252, this value is denoted as the FO sensor 252 in FIG. 7. As shown in FIG. 4, for the FO sensor, the detection unit 254 is horizontally arranged at the suction port 221D and the entrance 221A of the first loading box. The receiving unit 252 is mounted on the left cover of the suction device 200, and the transmitting unit 253 is mounted on the right cover of the suction device 200. The FO sensor according to an embodiment has 8 BITs of 0 and 1. When FO is sensed, the value of 0 changes to 1. 5 BITs are arranged at the suction port 221D, and 3 BITs are arranged at the entrance 221A of the first loading box. If the 3 BITs at the entrance 221A of the first loading box are detected as a value other than 0, it means that a heavy FO has been collected. A weight is added to this value to determine whether the transfer device 220 operates.

[0016] In addition, the controller 10 can save the BIT value when the FO sensor senses FO in the memory of the internal database or send it externally, and can include the position information and time information when FO is sensed. Increasing the 8 - BIT FO sensor to more than 8 BITs and increasing the number of light rays in the detection unit 245 of the same width can detect a smaller - sized FO. However, in an embodiment of the present disclosure, in order to improve the processing efficiency of heavy FO, considering the width of the suction port 221D, the width of the detection unit 254 is set to sense an FO of a certain size or more. This does not limit the number of BITs of the FO sensor and is only an example of sensing and processing FO.

[0017] The drive member of the dustpan 210 will be described. As shown in FIGS. 12 and 13, one or more types of sensors are mounted on the dustpan drive rod 213, but the type and mounting position of the sensors are not limited, and those having ordinary knowledge in the technical field can variously modify and implement it without departing from the gist of the present invention. One side of the dustpan drive rod 213 is coupled to the dustpan 210, and the other side is spanned on the dustpan drive cylinder 211. The sensor 214 mounted below the dustpan drive rod 213 is used for the purpose of measuring the distance between the road surface and the dustpan to ensure safety so that the road surface and the dustpan 210 do not collide, and for the purpose of maintaining the distance between the road surface and the dustpan 210 constant to improve the efficiency of the sweeper module. Since the dustpan drive rod 213 is not fixed to the dustpan drive cylinder 211, when a force such as an impact with the road surface acts, it can disengage from the dustpan drive cylinder 211 and rise together with the dustpan 210 to function as a protection against impact. When the dustpan drive cylinder 211 is actuated by the value calculated by the controller 10, the dustpan 210 is raised or lowered by the dustpan drive rod 213.

[0018] The injection member will be described. As shown in FIGS. 14 to 16, in one embodiment, the injection member 320 has a hollow swing arm 331 serving as a passage for fluid movement, and an up-and-down drive cylinder 330 connected to one end of the swing arm 331 expands and contracts, and the swing arm 331 controls the injection member 320 to descend during the operation of the sweeper module so as to adjust the road surface target point 310A according to the working speed of the injection member 320, or is controlled to advantageously rise during the movement of the vehicle when the sweeper module stops. The air flow discharged for the turbo fan 20 to form a vacuum is transmitted through the passage of the swing arm 331, and the peripheral air flow rate is amplified through the shroud 300 located around it, or the wind pressure generated during vehicle travel is collected and injected toward the road surface target point 310A. In one embodiment, the injection member 320 scatters the FO on the road surface. The scattered FO hits the inclined dust pan 210 and rises, and is removed by the vacuum formed at the suction port 221D by the filter 30 of the loading box, or stays at the first loading box inlet 221A and then is removed by moving to the first loading box 220 during the operation of the transfer device 240, thereby improving the performance of the sweeper module and the FO removal rate.

Those having ordinary knowledge in the technical field to which the present invention pertains will be able to understand that the present invention can be realized in a modified form without departing from the essential characteristics of the present invention.
