Description

Technical Field

[0001] This application relates to the field of cleaning robot technology, and in particular to a dust removal device and a cleaning robot. Background Technology

[0002] A sweeper is a specialized cleaning device that is electrically powered and integrates sweeping and vacuuming functions. It achieves floor cleaning through a roller brush working principle and has high operating efficiency.

[0003] The sweeper includes a vehicle body, inside which a roller brush is rotatably connected. A collection bin is located at the dust outlet end of the roller brush. In related technologies, the sweeper starts sweeping the ground, and dust and other waste are transported to the collection bin via rollers. Once the waste in the collection bin reaches a certain level, the operator opens the vehicle door and pulls out the collection bin to process and discharge the waste.

[0004] The above-mentioned method of manually removing dust from the sweeper requires the sweeper to stop working and wait for the operator to empty the collection bin, which interrupts the continuity of the cleaning work, is time-consuming and labor-intensive, and affects the sweeper's cleaning efficiency. Summary of the Invention

[0005] To address the issue of manual dust removal by operators, which requires the sweeper to stop and wait for the operator to empty the collection bin, disrupting the cleaning process, wasting time and effort, and affecting the sweeper's cleaning efficiency, this application provides a dust removal device with the following technical solution: It includes a mounting frame installed inside the vehicle body, on which a dust collection device, a conveying device, and a dust removal device are mounted. The dust collection device collects waste material from the roller brush cleaning process, the conveying device transports the waste material from the dust collection device to the dust removal device, and the dust removal device discharges the waste material from the vehicle body.

[0006] In one specific implementation, the dust collection device includes a dust collection chamber mounted on a mounting frame, and the dust collection chamber has a dust collection port on its end face facing the roller brush.

[0007] In one specific implementation, the conveying device includes a first spiral section and a second spiral section rotatably connected within the dust collection bin. The feed end of the first spiral section faces the roller brush, the discharge end of the first spiral section corresponds to the feed end of the second spiral section, and the discharge end of the second spiral section corresponds to the feed end of the dust removal device. The mounting frame is provided with a first driving part for driving the first spiral section to rotate and a second driving part for driving the second spiral section to rotate.

[0008] In one specific implementation, a third spiral section is rotatably connected inside the dust collection chamber, the third spiral section is disposed between the first spiral section and the second spiral section, and a third driving section is provided on the mounting frame to drive the third spiral section to rotate.

[0009] In one specific implementation, the first spiral part includes a long rod disposed at the output end of the first drive part, the long rod being not less than the extension length of the inner spiral block, the outer edge of the long rod being provided with an inner spiral block, and the inner spiral block being provided with a flexible spiral block.

[0010] In one specific implementation scheme, the flexible spiral block is provided with mounting bolts that pass through the flexible spiral block and the inner spiral block in sequence, and mounting nuts are threaded onto the mounting bolts. The mounting nuts are pressed against the end face of the inner spiral block.

[0011] In one specific implementation, the first spiral part includes a short rod disposed at the output end of the first drive part, and an elastic spiral block is provided at the end of the short rod opposite to the first drive part, and the short rod is shorter than the extension length of the elastic spiral block.

[0012] In one specific implementation, the dust removal device includes a dust removal pipe mounted on a mounting frame, the dust removal pipe being located at the discharge end of the conveying device and partially extending out of the vehicle body.

[0013] In one specific implementation, the dust exhaust pipe is rotatably connected to a mounting frame, the mounting frame is equipped with a drive electric cylinder, and the dust exhaust pipe is located at the output end of the drive electric cylinder.

[0014] In one specific implementation, a cleaning robot includes the aforementioned dust removal device.

[0015] In summary, this application has the following beneficial technical effects: the waste swept by the roller brush falls into the dust collection device for collection. When it is necessary to discharge the waste in the dust collection device, the conveying device is used to transport the waste in the dust collection device to the dust discharge device, and the dust discharge device discharges the waste from the vehicle body, realizing the fully automatic dust discharge of the sweeper. Through the automatic linkage of dust collection, conveying and dust discharge, the sweeper does not need to stop and wait for manual cleaning, realizing the fully automated closed loop of "sweeping-collection-discharge", ensuring the continuity and efficiency of cleaning work, greatly reducing manual intervention and maintenance time, saving time and labor while improving cleaning efficiency.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] Example 1 This application discloses an ash removal device.

[0025] Reference Figure 1 and Figure 2 The dust removal device includes a mounting frame 1 installed inside the vehicle body 15. In this embodiment, the dust removal device is used in a roller brush 16 cleaning robot as an example. The mounting frame 1 is detachably connected to the vehicle body 15 of the roller brush 16 cleaning robot via mounting bolts. A roller 14 is rotatably connected to the mounting frame 1, located between the mounting frame 1 and the vehicle body 15. The roller 14 facilitates the operator in pulling the dust removal device out of the roller brush 16 cleaning robot. During installation, the mounting frame 1 is first pushed into the vehicle body 15 using the roller 14. Then, the operator further secures the mounting frame 1 to the frame inside the vehicle body 15 using bolts. Finally, the door of the roller brush 16 cleaning robot is closed.

[0026] Reference Figure 1 and Figure 2The mounting frame 1 is equipped with a dust collection device, a conveying device, and a dust discharge device. The dust collection device collects the waste swept by the roller brush 16, the conveying device transports the waste from the dust collection device to the dust discharge device, and the dust discharge device discharges the waste from the vehicle body 15. Therefore, the waste swept by the roller brush 16 falls into the dust collection device for collection. When it is necessary to discharge the waste from the dust collection device, the conveying device transports the waste from the dust collection device to the dust discharge device, which discharges the waste from the vehicle body 15, achieving fully automatic dust discharge for the sweeper. Through the automated linkage of dust collection, conveying, and dust discharge, the sweeper does not need to stop and wait for manual cleaning, realizing a fully automated closed loop of "sweeping-collection-discharge," ensuring the continuity and efficiency of cleaning work, greatly reducing manual intervention and maintenance time, saving time and labor while improving cleaning efficiency.

[0027] Reference Figure 1 and Figure 2 The dust collection device includes a dust collection chamber 2 mounted on the mounting frame 1. A dust collection port 3 is provided on the end face of the dust collection chamber 2 facing the roller brush 16. The waste material obtained by the roller brush 16 from sweeping the ground falls into the dust collection chamber 2 through the dust collection port 3 and is collected in a concentrated manner.

[0028] Reference Figure 1 and Figure 3 The conveying device includes a first spiral part 4 and a second spiral part 5 rotatably connected in the dust collection bin 2. The feed end of the first spiral part 4 is arranged facing the roller brush 16, the discharge end of the first spiral part 4 corresponds to the feed end of the second spiral part 5, and the discharge end of the second spiral part 5 corresponds to the feed end of the dust removal device. The first spiral part 4 in the dust collection bin 2 can be arranged in an array of multiple units. In this embodiment, four units are used as an example for illustration. The second spiral part 5 is arranged on the side of the four first bolts away from the roller brush 16, and the conveying directions of the first spiral part 4 and the second spiral part 5 are perpendicular.

[0029] Reference Figure 1 and Figure 3The mounting frame 1 is equipped with a first driving unit that drives the first spiral part 4 to rotate and a second driving unit that drives the second spiral part 5 to rotate. A third spiral part 6, which is vertically arranged, is rotatably connected inside the dust collection bin 2. The third spiral part 6 is positioned between the first spiral part 4 and the second spiral part 5. The mounting frame 1 is equipped with a third driving unit that drives the third spiral part 6 to rotate. The structures of the second spiral part 5 and the third spiral part 6 can be configured with reference to the first spiral part 4. In this embodiment, the first driving unit includes a first motor mounted on the mounting frame 1. A first driving sprocket is mounted on the output end of the first driving motor. First transmission sprockets are fixedly sleeved on the ends of the four first spiral parts 4 facing the first motor. Several chains are wound between the first driving sprockets and the four first transmission sprockets, with chains wound between adjacent first transmission sprockets and between the first driving sprocket and the first transmission sprocket closest to it. The second and third driving units can be configured with sprocket and chain drives as in the prior art, corresponding to the first driving unit, or they can be configured with rack and pinion drives according to the actual site conditions.

[0030] Reference Figure 1 and Figure 4 The first spiral section 4 includes a long rod 7 disposed at the output end of the first drive section. One end of the long rod 7 facing the roller brush 16 is rotatably connected to the mounting frame 1, and the other end is fixedly fitted with a first transmission sprocket. The first transmission sprocket of the long rod 7 is connected to the first drive sprocket at the output end of the first motor through the structure of the sprocket chain. The long rod 7 is not less than the extension length of the inner spiral block 8. The outer edge of the long rod 7 is welded to the inner spiral block 8. A flexible spiral block 9 is installed on the inner spiral block 8. In this embodiment, the flexible spiral block 9 can be made of rubber. When granular ash enters the gap, the flexible spiral block 9 can use its own flexible properties to change its radial and axial shapes to produce appropriate deformation, so as to smoothly transport the dust and reduce the possibility of jamming or stopping the spiral conveyor in the dust collection bin 2.

[0031] Reference Figure 1 and Figure 4 The flexible spiral block 9 is provided with mounting bolts that pass through the flexible spiral block 9 and the inner spiral block 8 in sequence. The mounting bolts are threaded with mounting nuts. The mounting nuts face the inner spiral block 8 and abut against the inner spiral block 8. The operator can remove the flexible spiral block 9 from the inner spiral block 8 by removing the bolts, so that the flexible spiral block 9 can be removed and is more flexible.

[0032] Reference Figure 1 and Figure 6The dust removal device includes a dust removal pipe 12 mounted on the mounting frame 1. The dust removal pipe 12 is located at the discharge end of the conveying device and partially extends out of the vehicle body 15. The dust removal pipe 12 is rotatably connected to the mounting frame 1. A drive cylinder 13 is mounted on the mounting frame 1, and the dust removal pipe 12 is located at the output end of the drive cylinder 13. Therefore, when the roller brush 16 cleaning robot moves to the dust removal position, the drive cylinder 13 is activated to drive the dust removal pipe 12 to rise, so that the dust removal pipe 12 is in the unfolded state. The third spiral part 6 transports dust and other impurities to the dust removal pipe 12, which is then discharged from the vehicle body 15 to the designated position, realizing the automatic dust removal function of the roller brush 16 robot. When the roller brush 16 cleaning robot has not reached the dust removal position, the drive cylinder 13 is activated to drive the dust removal pipe 12 to retract, so that the dust removal pipe 12 is in the folded state. At this time, the roller brush 16 cleaning robot does not remove dust. The dust removal pipe 12 in the folded state does not occupy extra space, ensuring that the robot can operate normally in a confined space.

[0033] The implementation principle of Embodiment 1 of this application is as follows: When the sweeping robot with roller brush 16 moves to the dust discharge position, the drive cylinder 13 is activated to drive the dust discharge pipe 12 to rise, so that the dust discharge pipe 12 is in the unfolded state. The waste obtained by the roller brush 16 from sweeping the ground falls into the dust collection bin 2 through the dust collection port 3 for centralized collection. The first drive unit is activated to transport the waste that has fallen into the dust collection bin 2 to the feeding end of the second spiral unit 5 through the first spiral unit 4. The second drive unit is activated to transport the dust and other waste through the second drive unit to the feeding end of the third spiral unit 6. The third drive unit is activated, and the third spiral unit 6 transports the dust and other waste to the dust discharge pipe 12, from which it is discharged from the vehicle body 15 to the designated position, realizing the fully automatic dust discharge of the sweeping machine. Through the automated linkage of dust collection, conveying, and dust discharge, the sweeping machine does not need to stop and wait for manual cleaning, realizing the fully automated closed loop of "sweeping-collection-discharge", ensuring the continuity and efficiency of cleaning work, greatly reducing manual intervention and maintenance time, saving time and labor while improving cleaning efficiency.

[0034] Example 2 Reference Figure 1 and Figure 5 The first spiral section 4 includes a short rod 10 disposed at the output end of the first drive section. An elastic spiral block 11 is fixedly connected to the end of the short rod 10 away from the first drive section. The short rod 10 is shorter than the extension length of the elastic spiral block 11. A first transmission sprocket is disposed at the end of the short rod 10 away from the elastic spiral block 11. The first transmission sprocket of the short rod 10 is connected to the first drive sprocket at the output end of the first motor through the structure of the sprocket and chain. The end of the short rod 10 away from the first transmission sprocket is suspended. The elastic spiral block 11 can appropriately change its own axis according to the trend of waste material conveying. By utilizing the elastic compression principle of the elastic spiral block 11, the possibility of the spiral conveyor plate getting stuck or stopping in the dust collection bin 2 is reduced, and the smoothness of dust discharge is improved.
