[0029] Example 1:

[0030] The embodiment of the present invention provides a cleaning and sweeping vehicle with a dirt separation system, such as Figures 1-6 As shown, it includes: a washing and sweeping vehicle body 1, a carriage 2 is arranged on the frame of the washing and sweeping vehicle body 1, and a clean water tank 3, a sewage tank 4 and a debris collection box 5 are arranged in sequence in the carriage 2, a first sewage outlet 6 and a first water inlet are arranged on the side wall of the sewage tank 4 from top to bottom, a second sewage outlet 7 and a second water inlet are arranged on the side wall of the debris collection box 5 from top to bottom, the first sewage outlet 6 is connected to the second sewage outlet 7, and the first water inlet is connected to the second water inlet, a sewage separation system is arranged in the carriage 2, the sewage separation system includes a first sewage separation mechanism, and the first sewage separation mechanism is arranged in the sewage tank 4;

[0031] A plurality of water sprinklers are provided at the bottom of the washing and sweeping vehicle body 1, and the water sprinklers are connected to the output end of the clean water pump through a clean water pipe, and the input end of the clean water pump is connected to the inside of the clean water tank 3;

[0032] A cleaning mechanism 8 is provided at the bottom of the washing and sweeping vehicle body 1, and the cleaning mechanism 8 is connected to the frame of the washing and sweeping vehicle body 1 through a first mounting bracket;

[0033] A sewage collector 9 is provided at the bottom of the washing and sweeping vehicle, which is connected to the frame of the washing and sweeping vehicle body 1 through a second mounting frame. A sewage pipe 10 is provided at the output end of the sewage collector 9, and the output end of the sewage pipe 10 is connected to the upper end of the sewage tank 4 away from the debris collection box 5.

[0034] The working principle and beneficial effects of the above technical solution are as follows: a clean water tank 3, a sewage tank 4 and a debris collection box 5 are sequentially arranged in the carriage 2 of the washing and sweeping vehicle body 1. Clean water is stored in the clean water tank 3. The clean water pump can extract clean water from the clean water tank 3 and spray it onto the ground from the sprinkler, thereby cleaning the ground. During the cleaning process, the cleaning mechanism 8 is started to clean the ground, and the sewage collector 9 is opened to suck the dirt on the ground. The dirt includes sewage and debris on the ground. The dirt flows into the sewage tank 4 through the sewage pipe 10. The first dirt separation mechanism can separate the sewage from the debris, so that the sewage is recovered into the sewage tank 4, and then the debris falls into the debris collection box 5 through the first sewage outlet 6 and the second sewage outlet 7. The separated debris is collected by the debris collection box 5, which enhances the debris collection capacity of the washing and sweeping vehicle, reduces the frequency of debris cleaning of the washing and sweeping vehicle, increases the single operation time of the washing and sweeping vehicle, and improves the utilization rate of the washing and sweeping vehicle.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1 As shown, a water pump 11 is provided on the outer wall of the sewage tank 4 close to the clean water tank 3. The input end of the water pump 11 is connected to the interior of the sewage tank 4 through a water pumping pipe 12, and the output end of the water pump 11 is connected to the interior of the clean water tank 3 through a drain pipe 13.

[0037] A liquid level sensor is provided in the sewage tank 4 , and a controller is provided on the outer wall of the sewage tank 4 . The controller is electrically connected to the liquid level sensor and the water pump 11 respectively.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the separated sewage flows into the sewage tank 4, and the small particles of impurities in the sewage can naturally settle in the sewage tank 4. The liquid level sensor can detect the actual liquid level of the sewage in the sewage tank 4. When the actual liquid level of the sewage exceeds the preset liquid level, the controller controls the water pump 11 to start, and the water pump 11 pumps the sewage on the upper part of the sewage tank 4 into the clean water tank 3, thereby reusing water resources and achieving the effect of saving water. It also reduces the frequency of water addition of the washing and sweeping vehicle, increases the washing and sweeping distance of the washing and sweeping vehicle after a single water addition, and further improves the utilization rate of the washing and sweeping vehicle.

[0039] Example 3

[0040] On the basis of Example 1 or 2, as Figure 1 As shown, a sewage pipe 14 is provided at the bottom of the sewage tank 4 , one end of the sewage pipe 14 is connected to the bottom of the sewage tank 4 , and the other end of the sewage pipe 14 is connected to the outside of the carriage 2 , and a sewage valve is provided at the output end of the sewage pipe 14 .

[0041] The working principle and beneficial effects of the above technical solution are as follows: by opening the drain valve, the sundries and sewage settled in the sewage tank 4 can be discharged from the drain pipe 14, making it easier for the washing and sweeping vehicle to be used next time.

[0042] Example 4

[0043] On the basis of any one of Examples 1-3, Figure 1 、 Figure 3 、 Figure 4 As shown, the first waste separation mechanism includes: a first filter screen 15, the first filter screen 15 is tilted and arranged in the sewage tank 4, the height of the first filter screen 15 close to the debris collection box 5 is lower than the height of the first filter screen 15 away from the debris collection box 5, and the end of the first filter screen 15 close to the debris collection box 5 is connected to the bottom wall of the first sewage outlet 6;

[0044] The first dirt separation mechanism also includes: a cleaning component, which is arranged above the first filter 15, and the cleaning component includes two spaced-apart rotating shafts 16, the front and rear ends of the two rotating shafts 16 are respectively rotatably connected to the front and rear side walls of the sewage tank 4, the center line of the two rotating shafts 16 is parallel to the upper surface of the first filter 15, a transmission wheel 17 is provided on the rotating shaft 16, a transmission belt 18 is provided between the two transmission wheels 17, and the two transmission wheels 17 are connected through the transmission belt 18. A number of mounting tubes 19 are equally spaced on the outer wall of the transmission belt 18, one end of the mounting tube 19 is connected to the outer wall of the transmission belt 18, and a cleaning rod 20 is slidably provided on the other end of the mounting tube 19, a cleaning plate 21 is provided at the end of the cleaning rod 20 away from the transmission belt 18, a first spring 22 is provided at the end of the cleaning rod 20 close to the transmission belt 18, and the first spring 22 is connected to the inner wall of the mounting tube 19.

[0045] The working principle and beneficial effects of the above technical solution are as follows: the sucked sewage flows into the sewage tank 4 through the sewage pipe 10, and the sewage can flow along the first filter 15 to the first sewage outlet 6. When the sewage flows through the first filter 15, the sewage can flow through the first filter 15 into the bottom of the sewage tank 4, and the debris flows along the first filter 15 into the first sewage outlet 6 and flows out from the second sewage outlet 7 to the debris collection box 5. A large amount of debris is collected by the debris collection box 5. During the flow of sewage, the sewage can push the cleaning plate 21 to slide along the upper surface of the first filter 15. The cleaning plate 21 can move the mounting tube 19 through the cleaning rod 20 and the first spring 22, and the mounting tube 19 drives the transmission belt 18 to transmit between the two transmission wheels 17, thereby driving multiple mounting tubes 19 to move synchronously, so that the cleaning plate 21 contacts the upper surface of the first filter 15 in turn and cleans the first filter 15. No external driving equipment is required during the cleaning process, which has an energy-saving effect.

[0046] Example 5

[0047] On the basis of any one of Examples 1-4, Figure 3 As shown, there are several first water inlets and several second water inlets, and the several first water inlets are arranged at equal intervals along the side wall of the sewage tank 4. The several first water inlets correspond one to one with the several second water inlets. A second filter screen 23 is arranged in the first water inlet, and a third filter screen 24 is arranged in the second water inlet.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the debris collected in the debris collection box 5 will also carry some sewage. Therefore, the sewage tank 4 and the debris collection box 5 are also connected through the first water inlet and the second water inlet. The heights of the first water inlet and the second water inlet are higher than the preset liquid level of the sewage in the sewage tank 4, so as to prevent sewage from flowing from the sewage tank 4 into the debris collection box 5. The collected debris accumulates in the debris collection box 5, and the sewage can be gathered under the action of gravity and flow into the sewage tank 4 through the second water inlet and the first water inlet, thereby completing the further recovery of the sewage. A third filter screen 24 is provided at the second water inlet, and a second filter screen 23 is provided at the first water inlet, which can block the debris in the debris collection box 5, prevent the debris from flowing into the sewage tank 4, and improve the cleanliness of the sewage entering the sewage tank 4.

[0049] Example 6

[0050] On the basis of Example 5, Figure 1 、 Figure 5 、 Figure 6As shown, the waste separation system also includes a second waste separation mechanism, which is arranged in the debris collection box 5. The second waste separation mechanism includes a first squeezing plate 25 and a second squeezing plate 26. The lower surface of the first squeezing plate 25 is located above the second sewage outlet 7. The outer wall of the first squeezing plate 25 is slidably connected to the inner wall of the debris collection box 5 up and down. A plurality of second springs 27 are provided on the upper end of the first squeezing plate 25. The upper end of the second spring 27 is connected to the inner wall of the upper end of the debris collection box 5. The lower end of the second spring 27 is connected to the upper surface of the first squeezing plate 25. The second squeezing plate 26 is located at the upper end of the first squeezing plate 25. Below the plate 25, the outer wall of the second extrusion plate 26 is connected to the inner wall of the debris collection box 5 for sliding up and down. A drive motor 28 is provided below the second extrusion plate 26. A reciprocating screw 29 is provided at the output end of the drive motor 28. A slider 30 is slidably connected to the reciprocating screw 29. A drive plate 31 is provided on the outer wall of the slider 30. The outer wall of the drive plate 31 is connected to the inner wall of the debris collection box 5 for sliding up and down. A number of third springs 32 are provided between the drive plate 31 and the second extrusion plate 26. One end of the third spring 32 is connected to the upper surface of the drive plate 31, and the other end of the third spring 32 is connected to the lower surface of the second extrusion plate 26.

[0051] The working principle and beneficial effects of the above technical solution are as follows: a second waste separation mechanism is also provided in the debris collection box 5. When the debris carrying sewage enters the debris collection box 5, the debris falls on the second squeezing plate 26, and the driving motor 28 is started. The driving motor 28 rotates to drive the reciprocating screw 29 to rotate. The rotation of the reciprocating screw 29 drives the slider 30 to reciprocate up and down along the outer wall of the reciprocating screw 29. The slider 30 drives the driving plate 31 to slide up and down on the inner wall of the debris collection box 5. When the driving plate 31 slides upward, the driving plate 31 drives the second squeezing plate 26 to slide upward through the third spring 32. The second squeezing plate 26 drives the debris to move in the direction close to the first squeezing plate 25. The upper end of the debris contacts the first squeezing plate 25. Under the joint squeezing of the first squeezing plate 25 and the second squeezing plate 26, the debris is more tightly spaced, thereby improving the debris collection capacity of the debris collection box 5. As the first squeezing plate 25 and the second squeezing plate 26 are squeezed, the moisture in the debris is squeezed out, and the squeezed out moisture can flow into the sewage tank 4 through the second water inlet and the first water inlet, which speeds up the sewage recovery efficiency, improves the sewage recovery effect, and further reduces the moisture in the debris. When the driving plate 31 drives the second squeezing plate 26 to move downward, the space between the first squeezing plate 25 and the second squeezing plate 26 increases, which facilitates more debris to flow into the debris collection box 5. A second spring 27 is provided at the upper end of the first squeezing plate 25, and a third spring 32 is provided between the second squeezing plate 26 and the driving plate 31. As the debris in the debris collection box 5 increases, the second spring 27 and the third spring 32 are gradually compressed, thereby further improving the debris collection capacity of the debris collection box 5, reducing the debris cleaning frequency of the washing and sweeping vehicle, increasing the single operation time of the washing and sweeping vehicle, and improving the utilization rate of the washing and sweeping vehicle.

[0052] Example 7

[0053] On the basis of Example 6, Figure 1 、 Figure 5 、 Figure 6 As shown, a mounting hole is provided on the upper surface of the second extrusion plate 26, and a rotating disc 33 is provided in the mounting hole. The outer wall of the rotating disc 33 is slidably connected to the inner wall of the mounting hole. A plurality of toggle bars 34 are provided on the upper surface of the rotating disc 33, and the plurality of toggle bars 34 are distributed in a circular array about the center of the rotating disc 33. A spline sleeve 35 is provided on the lower surface of the rotating disc 33, and the outer wall of the spline sleeve 35 passes through the center of the second extrusion plate 26 and is rotatably connected to the second extrusion plate 26. A spline shaft 36 is slidably provided in the spline sleeve 35, and the lower end of the spline shaft 36 is connected to the upper end of the reciprocating screw 29.

[0054] The working principle and beneficial effects of the above technical solution are as follows: when the reciprocating screw 29 rotates, the reciprocating screw 29 drives the spline shaft 36 to rotate, and the spline shaft 36 drives the spline sleeve 35 to rotate in the second extrusion plate 26, and the spline sleeve 35 drives the rotating disc 33 to rotate in the mounting hole of the second extrusion plate 26. When the rotating disc 33 rotates, it drives multiple toggle bars 34 to rotate. The toggle bars 34 can toggle the debris in the debris collection box 5, so that the debris moves. During the movement of the debris, the sewage can be thrown out, and the thrown sewage can flow into the sewage tank 4. Through the above solution, the debris and sewage are further separated, the sewage and debris separation capacity of the sewage separation system is improved, water resources can be reused, and it is more energy-saving and environmentally friendly.
