[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 is a structural schematic diagram of the rolling brush assembly 100 provided by the embodiments of the present application in one perspective view, Figure 2 is an exploded view of the rolling brush assembly 100 provided by the embodiments of the present application, Figure 3 is a cross-sectional view of the rolling brush assembly 100 provided by the embodiments of the present application, Figure 4FIG. 1 is a structural schematic diagram of a shielding piece 14 provided in an embodiment of the present application. An embodiment of the present application provides a collecting device, which comprises a machine body and a rolling brush assembly 100. A mounting bracket 11 of the rolling brush assembly 100 is connected to the machine body of the collecting device. The rolling brush assembly 100 is used to collect the objects to be collected on the ground, so as to keep the ground clean. In some embodiments, the collecting device further comprises a collecting structure connected to the machine body of the collecting device, and the rolling brush assembly 100 is mounted on the collecting structure. The collecting structure comprises a collecting bin. The rolling brush assembly 100 is used to sweep the objects to be collected into the collecting bin. Exemplarily, the collecting device in an embodiment of the present application is described by taking a lawn mower as an example. The lawn mower further comprises a cutting structure mounted on the machine body, which is used to cut and trim the lawn. The rolling brush assembly 100 is used to sweep the grass clippings, fallen leaves and the like on the ground into the collecting bin. In some embodiments, the collecting device can also be configured as other devices, such as a road sweeping device, a household / industrial sweeping device, but is not limited thereto.

[0032] The rolling brush assembly 100 comprises the mounting bracket 11, a rotating piece 12, a rolling brush 13 and the shielding piece 14. The rotating piece 12 is rotatably mounted on the mounting bracket 11. The rolling brush 13 is mounted on the rotating piece 12. The rotating piece 12 is used to drive the rolling brush 13 to rotate, so as to sweep the objects to be collected. The shielding piece 14 is located between the mounting bracket 11 and the rolling brush 13. The shielding piece 14 is arranged around the rotating piece 12. The shielding piece 14 is used to shield the gap between the rolling brush 13 and the mounting bracket 11. In this way, the shielding piece 14 can shield the objects to be collected, so as to avoid the problem that the objects to be collected are concentrated in the gap between the rolling brush 13 and the mounting bracket 11 and wound in the gap at the connection between the rolling brush 13 and the mounting bracket 11, and the problem that the rolling brush 13 is stuck by the objects to be collected and cannot rotate, thereby improving the service life of the rolling brush assembly 100 and the operation reliability of the collecting device. In addition, the radius of the shielding piece 14 is greater than the radius of the rotating piece 12. The shielding piece 14 can increase the winding radius of the objects to be collected, improve the difficulty of winding the objects to be collected on the shielding piece 14, and effectively avoid the winding of the objects to be collected on the shielding piece 14.

[0033] The rotating member 12 is in a strip shape. The shielding member 14 is in a hollow cylinder shape. The rotating member 12 is arranged in the shielding member 14. The shielding member 14 is arranged independently relative to the mounting support 11 and the rotating member 12. The rotating member 12 comprises a body member 121 and a connecting member 122. The connecting member 122 is fixedly connected to the axial end of the body member 121. The connecting member 122 is arranged in the shielding member 14 and is used to be rotatably connected with the mounting support 11. The connecting member 122 is arranged in two, and the two connecting members 122 are correspondingly arranged at the two ends of the body member 121. Among them, the connecting member 122 and the body member 121 can be detachably connected, so as to facilitate the maintenance or replacement of the body member 121 or the connecting member 122 alone, and reduce the maintenance cost of the rotating member 12. The rolling brush 13 is arranged on the body member 121.

[0034] In some embodiments, the end of the rolling brush 13 is provided with a fixing groove 1311. The connecting member 122 is provided with a fixing protrusion 1222. The fixing protrusion 1222 is located in the fixing groove 1311. Among them, the shape of the fixing protrusion 1222 matches the shape of the fixing groove 1311, so that the fixing protrusion 1222 is clamped with the fixing groove 1311, thereby improving the connection stability of the rolling brush 13 and the body member 121, and avoiding the relative rotation of the rolling brush 13 and the body member 121.

[0035] Along the direction of the rotating axis of the rotating member 12, the radial dimension of the shielding member 14 at the position between the opposite ends is smaller than the radial dimension of the end of the shielding member 14 close to the mounting support 11. The end of the shielding member 14 close to the mounting support 11 is arranged in a substantially trumpet shape. In this way, when the to-be-collected object falls on the shielding member 14, the to-be-collected object will move away from the mounting support 11 under the guidance of the outer side wall of the shielding member 14, so as to reduce the contact opportunity of the to-be-collected object with the mounting support 11, and avoid the to-be-collected object being stuck between the shielding member 14 and the mounting support 11. Among them, the radial dimension is the dimension in the direction perpendicular to the direction of the rotating axis of the rotating member 12, and the radial dimension of the shielding member 14 can be the diameter of the circumscribed circle of the shielding member 14.

[0036] In some embodiments, along the direction of the rotating axis of the rotating member 12, the radial dimension of the shielding member 14 decreases from the opposite ends of the shielding member 14 to the middle part of the shielding member 14. The shielding member 14 has a structure of large at both ends and small in the middle. In this way, when the to-be-collected object falls on the shielding member 14, the to-be-collected object will move from the two ends of the shielding member 14 to the middle of the shielding member 14 under the guidance of the outer side wall of the shielding member 14, so as to make the to-be-collected object move away from the mounting support 11 and the rolling brush 13, and avoid the to-be-collected object being stuck or wound between the mounting support 11 and the shielding member 14, and between the rolling brush 13 and the shielding member 14.

[0037] The cross section of the shielding member 14 can be configured as a circle, so that external force acting on the shielding member 14 can be conducted to all parts of the shielding member 14, which is beneficial to avoid deformation of the shielding member 14, thereby improving the working reliability of the roller brush assembly 100. The cross section is a plane perpendicular to the rotation axis of the rotating member 12. In some embodiments, the cross section of the shielding member 14 can also be other shapes, for example, the cross section of the shielding member 14 includes but is not limited to a triangle, a square, an ellipse, a regular or irregular polygon, etc.

[0038] The shielding member 14 includes a first end portion 141, a second end portion 142, and an intermediate portion 143. The intermediate portion 143 is connected between the first end portion 141 and the second end portion 142. The intermediate portion 143 corresponds to a position between the opposite ends of the shielding member 14. The first end portion 141 is connected to the mounting bracket 11. The radial dimension of the intermediate portion 143 is smaller than the radial dimension of the first end portion 141 and the radial dimension of the second end portion 142, respectively. In this way, when the to-be-collected object falls on the shielding member 14, the to-be-collected object will move towards the intermediate portion 143 due to the guiding effect of the shielding member 14.

[0039] In some embodiments, the radial dimension of the shielding member 14 can gradually decrease from the first end portion 141 and the second end portion 142 towards the intermediate portion 143, for example, it can decrease linearly or non-linearly. In some embodiments, along the direction from the first end portion 141 towards the intermediate portion 143, the radial dimension of the shielding member 14 can first remain unchanged and then gradually decrease. In some embodiments, along the direction from the second end portion 142 towards the intermediate portion 143, the radial dimension of the shielding member 14 can first remain unchanged and then gradually decrease.

[0040] The shielding member 14 is mounted on the mounting bracket 11. The shielding member 14 and the mounting bracket 11 can be detachably connected, which is beneficial to the maintenance or replacement of the shielding member 14. The shielding member 14 is provided with a clamping portion 145. The clamping portion 145 is located at one end of the shielding member 14 close to the mounting bracket 11. The clamping portion 145 is connected to the first end portion 141 and extends away from the rotating member 12 relative to the first end portion 141. The mounting bracket 11 is provided with a clamping groove 1111. The clamping portion 145 is clamped and fixed in the clamping groove 1111, so as to avoid rotation of the shielding member 14 relative to the mounting bracket 11, and fix the shielding member 14 relative to the mounting bracket 11. The first end portion 141 is fixed relative to the mounting bracket 11 through the clamping portion 145.

[0041] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 5is a structural schematic diagram of a rolling brush 13 provided by an embodiment of the present application, Figure 6 is a structural schematic diagram of a rolling brush assembly 100 provided by an embodiment of the present application, Figure 7 is Figure 6 is an enlarged view of I in FIG. 10. The rolling brush 13 is provided with an avoiding groove 1320. The avoiding groove 1320 has an opening close to one side of the shielding piece 14. An end of the shielding piece 14 away from the mounting bracket 11 is located in the avoiding groove 1320, i.e., the second end portion 142 is located in the avoiding groove 1320. The shielding piece 14 has an extension length greater than the distance between the rolling brush 13 and the mounting bracket 11, so that the shielding piece 14 shields the gap between the rolling brush 13 and the mounting bracket 11, and avoids the collected object from forming a winding to hinder the rotation of the rolling brush 13.

[0042] The radial dimension of the shielding piece 14 decreases from the second end portion 142 to the middle portion 143. The middle portion 143 and the second end portion 142 can be arranged in a smooth transition to reduce the resistance when the collected object slides along the circumferential wall of the shielding piece 14, and facilitate the collected object to slide from the position close to the second end portion 142 to the position of the middle portion 143, effectively avoiding the collected object from entering the avoiding groove 1320.

[0043] The avoiding groove 1320 is spaced apart from the rotating piece 12. The avoiding groove 1320 does not penetrate the inner wall of the rolling brush 13 toward the side of the rotating piece 12. In this way, the rolling brush 13 can extend to the position between the shielding piece 14 and the rotating piece 12, so that the rolling brush 13 and the shielding piece 14 form a snap fit, and the groove wall of the avoiding groove 1320 and the second end portion 142 form a C-shaped bending structure. Even if the collected object enters the avoiding groove 1320, the collected object will be clamped between the side surface of the second end portion 142 away from the rotating piece 12 and the groove side wall of the avoiding groove 1320, thereby facilitating the collected object to avoid entering the position between the end surface of the second end portion 142 away from the mounting bracket 11 and the groove bottom wall of the avoiding groove 1320, avoiding the collected object from exerting an external force on the rolling brush 13 in the direction of the rotation axis of the rotating piece 12, and further avoiding the connection between the body piece 121 and the connecting piece 122 from failing to disengage, and avoiding the collected object from entering the position between the shielding piece 14 and the rotating piece 12.

[0044] The rolling brush 13 includes a sleeve 131 and a brush body 132. The sleeve 131 is sleeved on the rotating piece 12 and is fixed relative to the rotating piece 12. The end of the sleeve 131 is provided with a fixing groove 1311. The shape of the cross section of the sleeve 131 can be configured as a square, a triangle, a circle, an ellipse, a regular or irregular polygon, etc. The shape of the cross section of the body piece 121 corresponds to the shape of the cross section of the sleeve 131, so that the sleeve 131 can be stably sleeved on the body piece 121, avoiding the sleeve 131 from rotating relative to the body piece 121, and facilitating the disassembly and assembly of the sleeve 131.

[0045] The brush body 132 is arranged on the side wall of the sleeve 131 away from the rotating member 12. The brush body 132 extends away from the sleeve 131. The avoiding groove 1320 is arranged on the brush body 132 to facilitate the processing of the avoiding groove 1320. The sleeve 131 extends between the shielding member 14 and the rotating member 12. Thus, the shielding member 14 can shield the end of the sleeve 131 to avoid the collected object winding between the sleeve 131 and the rotating member 12.

[0046] In some embodiments, the end of the sleeve 131 can be flush with the end of the brush body 132 along the rotation axis of the rotating member 12, or the end of the sleeve 131 can be protruding relative to the end of the brush body 132. In some embodiments, the end of the brush body 132 can be protruding relative to the end of the sleeve 131 along the rotation axis of the rotating member 12, and the sleeve 131 and the shielding member 14 can be spaced apart along the rotation axis of the rotating member 12.

[0047] The brush body 132 includes a base 1321, a first brush part 1322, and a second brush part 1323. The base 1321 is connected to the sleeve 131 and extends away from the rotating member 12. The first brush part 1322 and the second brush part 1323 are connected to the side of the base 1321 away from the sleeve 131. The first brush part 1322 and the second brush part 1323 extend away from the base 1321, respectively. The extending direction of the first brush part 1322 is different from the extending direction of the second brush part 1323. The first brush part 1322 and the second brush part 1323 are alternately spaced along the rotation direction of the rotating member 12. The first brush part 1322 includes a plurality of bristles arranged along the rotation axis of the rotating member 12. The second brush part 1323 includes a brush plate or a plurality of brush plates arranged along the rotation axis of the rotating member 12. The width of the brush plate is greater than the width of the bristle along the rotation axis of the rotating member 12. The brush plate can effectively increase the winding radius of the collected object and improve the difficulty of the collected object winding on the roller brush 13, thereby effectively avoiding the collected object winding on the roller brush. The first brush part 1322 and the second brush part 1323 can be curved, respectively.

[0048] The avoiding groove 1320 can be arranged on the base 1321. In some embodiments, the thickness of the base 1321 is greater than the thickness of the first brush part 1322 and the thickness of the second brush part 1323 respectively. In this way, the avoiding groove 1320 is arranged on the thicker base 1321, so that the brush body 132 still has sufficient structural strength after the avoiding groove 1320 is opened, and the stable connection between the brush body 132 and the sleeve 131 is ensured. In some embodiments, the avoiding groove 1320 can also be arranged on the first brush part 1322 and the second brush part 1323.

[0049] The rolling brush assembly 100 further comprises a bearing 15. The shielding piece 14 is formed with a containing space 140. The bearing 15 is located in the containing space 140. The shielding piece 14 is connected with the outer ring of the bearing 15. The side of the containing space 140 away from the mounting bracket 11 has an opening. The rotating piece 12 is arranged in the containing space 140 and connected with the inner ring of the bearing 15.

[0050] The inner wall of the shielding piece 14 is provided with a first abutting part 144. The first abutting part 144 abuts against the outer ring of the bearing 15. The outer wall of the rotating piece 12 is provided with a second abutting part 1221. The second abutting part 1221 abuts against the inner ring of the bearing 15. One of the first abutting part 144 and the second abutting part 1221 is located on the side of the bearing 15 away from the mounting bracket 11, and the other is located on the side of the bearing 15 close to the mounting bracket 11, i.e. the first abutting part 144 and the second abutting part 1221 are located on the opposite sides in the axial direction of the bearing 15, so that the bearing 15 is clamped between the first abutting part 144 and the second abutting part 1221, achieving the installation and fixation of the bearing 15, and avoiding the movement of the bearing 15 along the direction of the rotation axis of the rotating piece 12. The connecting piece 122 is located in the containing space 140 and fixedly connected with the inner ring of the bearing 15. The second abutting part 1221 is arranged on the connecting piece 122. The axial direction of the bearing 15 is parallel to the direction of the rotation axis of the rotating piece 12.

[0051] In some embodiments, the first abutting part 144 and the second abutting part 1221 can be configured as abutting protrusions, and the side wall of the abutting protrusion abuts against the bearing 15. In some embodiments, the first abutting part 144 and the second abutting part 1221 can be configured as abutting grooves, and the bearing 15 is located in the abutting groove, and the side groove wall of the abutting groove abuts against the bearing 15.
