The structure of the railing cleaning device 3 is shown in Fig. 5, Fig. 6, Fig. 7, and Fig. 8, mainly including a sub-storage box 303, a railing brush 304 and a second motor 320, and the railing brush 304 is installed in the sub-storage box 303; when the railing cleaning device 3 is working, the railing brush 304 is in an extended state relative to the sub-storage box 303, and the railing brush 304 is driven to rotate relative to the sub-storage box 303 by the second motor 320, and can be used The railing brush 304 cleans the railings. As shown in Fig. 11, Fig. 12 and Fig. 13, the dust suction and cleaning device 4 includes a negative pressure device 401 and a ground brush 402. The ground brush 402 is arranged at the bottom of the vehicle frame 1, and the ground brush 402 passes through the fifth The motor 409 is driven to rotate relative to the vehicle frame 1, and the negative pressure exhaust duct 13 is arranged on the vehicle frame 1. The negative pressure exhaust duct 13 communicates with the negative pressure device 401 and the automatic dust suction channel 11 respectively. The rubbish cleaned by the brush 402 enters the automatic dust suction channel 11 through the negative pressure adsorption effect generated by the negative pressure device 401 .

When the above-mentioned modular multifunctional cleaning machine is working, the railing brush 304 on the railing cleaning device 3 is used to clean the railings. After the brush 402 cleans, it enters the automatic dust collection channel 11 by using the negative pressure adsorption effect generated by the negative pressure device 401, and finally enters the dustbin 501, so that the continuous cleaning operation of the railings and the ground can be realized, and Garbage generated during the cleaning process can also be transported to the garbage bin 501 in a closed manner, which not only improves the efficiency and quality of the cleaning operation, but also reduces the labor intensity of the cleaning operation.

In order to conveniently adjust the cleaning operation area of the ground brush 402 to further improve the cleaning efficiency and cleaning quality, as shown in FIG. There are two ground brushes 402, which are distributed on opposite sides of the vehicle frame 1; each ground brush 402 is movably connected with the second sliding seat 406 through an independent second connecting rod 405. A screw drive mechanism is formed between the second sliding seat 406 and the driving screw 403, the driving screw 403 is driven by the fourth motor 404, and the fourth motor 404 is fixedly installed on the vehicle frame 1, when When the fourth motor 404 is working, the rotation of the driving screw 403 can make the ground brush 402 move in translation relative to the vehicle frame 1 .

Further, the guide rail 407 can be fixedly installed on the vehicle frame 1, and a relatively sliding movable connection structure is formed between the ground brush 402 and the guide rail 407, and the ground brush 402 is relative to the vehicle frame under the action of the driving screw 403 1 translates along the guide rail 407. Wherein, the guide rail 407 adopts an L-shaped guide rail, so that the ground brush 402 can form an L-shaped translational trajectory relative to the vehicle frame 1 under the action of the driving screw 403, that is, two opposite ground brushes The distance between the brushes 402 can be adjusted within a certain range. A guide chute 408 can also be formed on the guide rail 407, the guide chute 408 is an L-shaped structure chute, the second connecting rod 405 is movably connected with the ground brush 402 through the guide pulley 410, and the guide pulley 410 and the ground brush 402 are movably connected. A rolling friction structure is formed between the guide grooves 408, and the guide pulley 410 preferably adopts a hollow disc structure, which can not only increase the translational flexibility of the ground brush 402, but also help reduce the motion wear caused by the ground brush 402.

With such a structural design, the fourth motor 404 drives the driving screw 403 to rotate, so that the second sliding seat 406 is lowered relative to the driving screw 403, and the guide pulley 410 is lowered along the guide chute 408 through the second connecting rod 405, Thereby, the ground brush 402 is lowered to a suitable cleaning height relative to the vehicle frame 1; subsequently, the second sliding seat 406 continues to descend, and the guide pulley 410 enters the horizontal part of the guide chute 408, thereby allowing the two ground brushes 402 to The horizontal distance of the ground brush 402 is enlarged, thereby achieving the effect of adjusting the distance between the ground brushes 402, so that the ground brush 402 can clean a larger working area and sweep in more garbage, thereby improving the cleaning efficiency and cleaning quality.

For the cleaning operation area that cannot be cleaned in place by railing brush 304 and floor brush 402, it can be cleaned by hand-held dust suction pipeline 12, and described hand-held dust suction pipeline 12 is communicated with negative pressure ventilation pipeline 13, as shown in Figure 12 and Figure 13 shown. In order to reduce the amount of dust in the cleaning operation and avoid secondary pollution caused by dust, a water storage tank 323 can be installed on the vehicle frame 1, and the water storage tank 323 is communicated with the water spray head 321 through the water spray pipeline 325. A water pump 324 is provided on the road 325, as shown in Fig. 9 and Fig. 10 .

After the cleaning operation is completed, start the spray pump 24, and the cleaning work area can be disinfected through the spray head 22.

When the railing brush 304 is not working, the railing brush 304 can be stored in the sub-storage box 303 by using the railing brush folding mechanism, so as to reduce the occupied space of the modular multifunctional cleaning machine. As shown in Figures 5-8, the railing brush folding mechanism includes a first guide rod 305, a first connecting rod 308 and a right screw 318, and a chute 322 is provided on the sub-storage box 303, so that the first sliding seat 309 can slide relative to the sub-storage box 303 within the range defined by the slide groove 322 . The chute 322 preferably adopts an elongated structure. The second motor 320 is connected to the swing rod 319, the swing rod 319 and the fixed support 327 form a relatively rotational movable connection, and the fixed support 327 is fixedly connected to the sub-storage box 303; The first guide rod 305 of the first guide rod 305 forms a relatively sliding movable connection structure with the right movable slide seat 317 and the first slide seat 309 respectively. Generally, a bar-shaped chute can be set on the first guide rod 305, and the right movable slide seat 317, the first sliding seat 309 respectively forms a relatively sliding movable connection structure with the first guide rod 305 through the bar-shaped slide groove. A screw drive mechanism is formed between the right movable sliding seat 317 and the right lead screw 318 , and the right lead screw 318 is driven by a first motor 315 . One end of the first connecting rod 308 forms a relative rotational connection with the swing rod 319 , and the other end of the first connecting rod 308 forms a relative rotation connection with the first sliding seat 309 .

When the railing brush folding mechanism works, the first motor 315 drives the right lead screw 318 to rotate, and the right lead screw 318 drives the right movable slide 317 to move linearly, and the right movable slide 317 drives the second slide through the first guide rod 305 A sliding seat 309 slides relative to the sub-storage box 303 within the range defined by the chute 322 , and finally the railing brush 304 is rotated relative to the sub-storage box 303 to a working state or a storage state through the first connecting rod 308 . In order to reduce the pressure on the first guide rod 305 when the railing brush 304 is in a storage state relative to the sub-storage box 303, an elastic sleeve 302 can be arranged between the first sliding seat 309 and the sub-storage box 303, and the elastic sleeve 302 One end is fixedly connected with the sub-storage box 303, and the other end forms a relative rotational connection with the first sliding seat 309, as shown in Fig. 5 and Fig. 6 .

In order to improve the automation level of the modular multifunctional cleaning machine, as shown in Figure 5-8, a mother storage box 301 and a cell-changing mechanism can be added. A mounting seat 332 is provided in the hollow inner cavity of 301 , and the first motor 315 is fixedly mounted on the mounting seat 332 . A screw drive mechanism is formed between the connecting seat 306 and the lifting screw 307, the lifting screw 307 is driven by the third motor 326, and the rotation of the lifting screw 307 drives the female storage box 301 through the connecting seat 306 Relative to the vehicle frame 1, it moves up and down in a straight line. The cell-changing mechanism includes a left lead screw 313, a left solenoid valve 314, a first motor 315, and a right solenoid valve 316. A screw drive mechanism is formed between the left lead screw 313 and the left movable slide seat 312. A left solenoid valve 314 is set between the first motor 315 and the left lead screw 313, and a right solenoid valve 316 is set between the first motor 315 and the right lead screw 318. The left solenoid valve 314, the first motor 315, the right solenoid valve The valves 316 are respectively electrically connected to the central controller, and the central controller preferably adopts a single-chip microcomputer.

Said mother storage box 301 and sub-storage box 303 form a movable connection structure that relatively linearly slides, and usually, a relatively linear-slide movable connection can be formed between the mother storage box 301 and the sub-storage box 303 by engaging slide rails 328 structure. The female storage box 301 forms a flexible connection structure with one end of the first guide rod 305 and one end of the second guide rod 310 through pins, and the second guide rod 310 forms a fixed sliding seat 311 and a left movable sliding seat 312 respectively. Relatively sliding movable connection structure, the fixed sliding seat 311 is fixedly connected with the sub-storage box 303, and a screw drive mechanism is formed between the left movable sliding seat 312 and the left screw 313. Driven by the left lead screw 313 to form an active connection structure that slides relatively linearly. The metamorphic mechanism drives the railing brush folding mechanism to act, and after the sub-storage box 303 extends to a designated position relative to the parent storage box 301, the railing brush folding mechanism drives the railing brush 304 to rotate relative to the sub-storage box 303 to the working state Or, after the railing brush folding mechanism drives the railing brush 304 to rotate relative to the sub-storage box 303 to the storage state, then the sub-storage box 303 is retracted to a designated position relative to the main storage box 301 . specifically:

The first motor 315 drives the left lead screw 313 and the right lead screw 318 to rotate at the same time until the child storage box 303 reaches the designated position relative to the mother storage box 301, the left solenoid valve 314 is disconnected, and the left lead screw 313 stops turn. What needs to be explained here is: let the left lead screw 313 and the right lead screw 318 rotate simultaneously. 303 rotates, that is, the railing brush 304 and the sub-storage box 303 remain relatively stationary. Because the action of the first sliding seat 309 is controlled by the right lead screw 318, and the first sliding seat 309 controls the rotation of the railing brush 304 relative to the sub-receiving box 303; if only the left lead screw 313 rotates, and the right Lead screw 318 does not rotate, then when child storage box 303 stretches out action relative to mother storage box 301, first slide seat 309 also can slide relative to child storage box 303 in the scope limited by chute 322, thus can As a result, the railing brush 304 rotates relative to the sub-storage box 303 , and movement interference easily occurs. Therefore, when the left lead screw 313 and the right lead screw 318 rotate simultaneously, the first sliding seat 309 and the sub-storage box 303 can be kept in a relatively static state, thereby ensuring that the railing brush 304 will not rotate relative to the sub-storage box 303 .

When the sub storage box 303 stretches out to the specified position relative to the main storage box 301, the left electromagnetic valve 314 is disconnected, and the first motor 315 continues to drive the right lead screw 318 to rotate, so that the first sliding seat 309 is defined by the chute 322. within the range of sliding relative to the sub-storage box 303, so that the railing brush 304 rotates relative to the sub-storage box 303, until the railing brush folding mechanism drives the railing brush 304 to rotate relative to the sub-storage box 303 to the working state, the right solenoid valve 316 is turned off Open, right leading screw 318 stops rotating. After the railing brush 304 is finished working, the right solenoid valve 316 starts and the first motor 315 reversely rotates until the railing brush folding mechanism drives the railing brush 304 to rotate relative to the sub-storage box 303 to the storage state, the left solenoid valve 314 Start, the first motor 315 continues to reversely drive the left lead screw 313 and the right lead screw 318 to rotate simultaneously until the child storage box 303 retracts to the designated position relative to the mother storage box 301, the left solenoid valve 314 and the right solenoid valve 316 Disconnect simultaneously, and left leading screw 313, right leading screw 318 all stop rotating.

In order to ensure the working reliability and safety of the above-mentioned modular multifunctional cleaning machine, a magnetic induction switch 329, a travel switch 330 and a trigger magnet 331 can be provided, and the magnetic induction switch 329 and the travel switch 330 are respectively electrically connected to the central controller , the trigger magnet 331 is installed on the sub-storage box 303; and, when the trigger magnet 331 moves to trigger the magnetic induction switch 329 to act, the sub-storage box 303 extends to a designated position relative to the main storage box 301. When the right lead screw 318 rotates until the right movable sliding seat 317 triggers the travel switch 330, the railing brush folding mechanism drives the railing brush 304 to rotate relative to the sub-storage box 303 to the working state.

During the working process of the modular multifunctional cleaning machine, when the garbage bin 501 is filled with garbage, the garbage in the garbage bin 501 needs to be dumped into the garbage disposal station to empty the garbage bin 501 . In order to facilitate the dumping operation of the dustbin 501, improve the efficiency of the dumping operation, and reduce the labor intensity of the operators, the dustbin 501 can be installed on the vehicle frame 1 through the automatic dumping device 5 . As shown in Fig. 14, Fig. 15, Fig. 16 and Fig. 17, the automatic dumping device 5 includes an assembly box 502, a third connecting rod 509, a fourth connecting rod 511 and its driving mechanism, and the fourth connecting rod 511 The drive mechanism includes an active screw 505 and a sliding connection seat 504, a screw transmission mechanism is formed between the active screw 505 and the sliding connection seat 504, and the active screw 505 is driven by a sixth motor 503, and the sliding The connecting seat 504 is fixedly connected with the third sliding block 512 . Wherein, the sliding connection seat 504 preferably adopts an L-shaped structural member, so that the active screw 505 and the sixth motor 503 can be arranged in the inner cavity of the assembly box 502 .

The assembly box 502 is fixedly connected with the vehicle frame 1, and a chute 508 is formed on the assembly box 502; generally, the chute 508 includes an overturning section 508a and a straight section 508b, and the overturning section 508a and the straight section 508b They communicate with each other to form a Y-shaped structure, and the turning section 508a is an arc-shaped structure. One end of the third connecting rod 509 is movably connected with the first slider 506, and the other end of the third connecting rod 509 and one end of the fourth connecting rod 511 form a flexible connection structure through the second slider 510. The other end of the connecting rod 511 is movably connected with the third slider 512. The first slider 506, the second slider 510, and the third slider 512 respectively form a sliding fit structure with the chute 508. The third slider The connecting rod 509 is fixedly connected with the dustbin 501 . When the dustbin 501 needs to be dumped, the dustbin 501 can be flipped relative to the vehicle frame 1 within a certain inclination angle under the action of the driving mechanism of the fourth connecting rod 511 . in particular:

The sixth motor 503 drives the active screw 505 to rotate, and the active screw 505 drives the sliding connection seat 504 to rise along the active screw 505, and the sliding connection seat 504 drives the third slider 512 to move along the chute 508 Straight segment 508b rises. When the third connecting rod 509 is in line with the fourth connecting rod 511, the turning mechanism is at the dead point, therefore, there will be no relative rotation between the third connecting rod 509 and the fourth connecting rod 511, so that the dustbin 501 also follows the The third connecting rod 509 rises together with the fourth connecting rod 511, as shown in FIG. 18 . When the first slider 506 continues to rise until the second slider 510 also enters the turning section 508a, a certain angle will be formed between the third connecting rod 509 and the fourth connecting rod 511, so that the dead point state of the turning mechanism destroyed. Further, a curved limiting section 508c may be formed at the end of the straight section 508b, and a V-shaped structure is formed between the curved limiting section 508c and the straight section 508b. When the first slider 506 rises and begins to enter the curved limiting section 508c , the second slider 510 also begins to enter into the turning section 508a, which makes it easy to form a certain angle between the third connecting rod 509 and the fourth connecting rod 511 due to the relative rotation. Therefore, the turning mechanism The dead point state is more easily broken. As the third slider 512 continues to rise along the straight section 508b of the chute 508, the second slider 510 is driven to continue sliding along the turning section 508a through the fourth connecting rod 511.
