Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weeding equipment, in particular to a rolling brush mechanism for a weeding equipment and a mower. BACKGROUND

[0002] With the advancement of technology, self-moving equipment gradually enters different fields, such as the field of mowing. The self-moving equipment such as the mower is used to realize labor-saving and effective mowing operation. However, during the mowing process, the grass clippings generated will usually accumulate on the surface of the grass, causing the plants on the surface to weaken due to lack of sunlight; at the same time, the overall ornamental value of the grass is also affected.

[0003] The traditional grass clippings cleaning method is usually divided into two types: 1. A grass collecting bag is configured, and the grass is collected into the grass collecting bag at the tail end of the machine by suction or a raking mechanism. However, the disadvantages are: the grass in the grass collecting bag needs to be emptied frequently, which wastes manpower and affects work efficiency; on the other hand, the weight of the grass collecting bag increases after collecting the grass, which increases the power consumption of the machine.

[0004] 2. A grass pressing wheel is configured to control the inclination direction of the grass surface to control the aesthetic value of the sun and the shade of the grass surface. However, the disadvantages are: the amount of grass clippings pressed into the grass surface is small, and the depth is not enough, which cannot be used as a separate solution for grass clippings cleaning. The above traditional grass clippings cleaning methods cannot effectively solve the problem of grass clippings accumulating on the surface of the grass. SUMMARY

[0005] Therefore, it is necessary to provide a rolling brush mechanism for a weeding equipment and a mower to solve the problem of grass clippings accumulating on the surface of the grass.

[0006] A rolling brush mechanism for a weeding equipment, the rolling brush mechanism for a weeding equipment comprising: a roller rotatable about its own axis; a brush cleaning piece having a first end and a second end arranged oppositely, the first end being connected to the roller, the brush cleaning piece being provided with at least one bending structure, the bending structure comprising a connecting portion, a brushing portion, and a bending portion connecting the connecting portion and the brushing portion, the connecting portion and the brushing portion forming an included angle at the bending portion, the connecting portion being arranged between the bending portion and the first end; the brushing portion being arranged between the bending portion and the second end; in at least one bending structure, the opening direction of the included angle is opposite to the rotation direction of the roller, so that the brushing portion presses the grass clippings contacted therewith towards the ground.

[0007] The brush roller mechanism for the grass removing device is applied to the grass removing device such as the mower. When the grass clippings are cleaned, the roller rotates around its axis, drives the cleaning brush to rotate with the roller, and makes the cleaning brush to sweep the grass clumps. Since the cleaning brush is provided with at least one bending structure, and the included angle between the connecting part and the sweeping part formed at the bending part in the at least one bending structure is opposite to the rotating direction of the roller, when the grass clumps are swept, the cleaning brush has a sweeping part which is bent and extends in the direction opposite to the rotating direction, and can press the grass clippings on the surface of the grass clumps, so as to reduce the lift force generated by the cleaning brush on the grass clippings when the cleaning brush leaves the grass surface, and make most of the grass clippings to be beaten into the grass clumps, thereby effectively improving the cleaning effect of the grass clippings.

[0008] In one of the embodiments, a first tangent line is formed by the tangent line of any point in the at least one section of the sweeping part, and a second tangent line is formed by the tangent line of any point in the at least one section of the connecting part, and the first tangent line intersects with the second tangent line.

[0009] In one of the embodiments, the sweeping part is bent on the connecting part in the form of a straight line included angle or an arc curvature.

[0010] In one of the embodiments, the roller is provided with a mounting position, and at least one cleaning brush is arranged on the same mounting position.

[0011] In one of the embodiments, one or two cleaning brushes are arranged on the same mounting position.

[0012] In one of the embodiments, a plurality of cleaning brushes are arranged, and the plurality of cleaning brushes are arranged along the circumferential direction of the roller.

[0013] In one of the embodiments, a plurality of cleaning brushes are arranged, and the plurality of cleaning brushes are arranged along the axis direction of the roller to form at least one cleaning brush assembly.

[0014] A mower, which comprises a machine body and the brush roller mechanism for the grass removing device according to any one of the above embodiments, and is provided with a grass cutting part with a cutting function, and the roller is rotatably arranged on the machine body, and the brush roller mechanism is used to press the grass clippings generated by the grass cutting part to the ground.

[0015] The above-described lawn mower adopts the above-described rolling brush mechanism for the weeding device. During the mowing process, the mowing part cuts the grass clump, and some grass clippings are left on the surface of the grass clump. Therefore, the roller is driven to rotate around its axis, and the cleaning brush rotates with the roller, so that the cleaning brush pushes away the grass clump. Since the cleaning brush is provided with at least one bending structure, and the included angle between the connecting part and the brushing part at the bending part in the at least one bending structure is opposite to the rotation direction of the roller, when the grass clump is pushed away, the cleaning brush has a brushing part that bends and extends in the direction opposite to the rotation direction, which can press the grass clippings on the surface of the grass clump to reduce the lift generated by the cleaning brush when it leaves the grass surface, so that most of the grass clippings are beaten into the grass clump, thereby effectively improving the grass clippings cleaning effect.

[0016] In one embodiment, the lawn mower can autonomously move and work in a working area defined by a boundary; the machine body has a walking module along the advancing direction, and the mowing part and the roller are sequentially arranged along the advancing direction on the machine body.

[0017] In one embodiment, the roller is at least two, and the at least two rollers are arranged at intervals along the advancing direction, and the rotation directions of any two adjacent rollers are the same or opposite.

[0018] In one embodiment, the lawn mower comprises a suspension device, and the roller is installed on the machine body through the suspension device.

[0019] In one embodiment, the lawn mower further comprises a roller height adjusting device configured to adjust the height of the roller when the required cutting height of the grass clump changes, so that the height of the roller is adapted to the height of the mowing part.

[0031] In order to make the above objectives, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0032] In one embodiment, please refer to Figure 1The application discloses a rolling brush mechanism 100 for a grass removing device, which comprises a rolling cylinder 110 and a brush cleaning piece 120. The rolling cylinder 110 can rotate around its own axis. The brush cleaning piece 120 has a first end 123 and a second end 124 arranged oppositely. The first end 123 is connected to the rolling cylinder 110. The brush cleaning piece 120 is provided with at least one bending structure 121. The bending structure 121 comprises a connecting part 1211, a brushing part 1212, a bending part 1215 connecting the connecting part 1211 and the brushing part 1212, and an included angle formed between the connecting part 1211 and the brushing part 1212 at the bending part 1215. The connecting part 1211 is arranged between the bending part 1215 and the first end 123, and the brushing part 1212 is arranged between the bending part 1215 and the second end 124. In the at least one bending structure 1212, the opening direction of the included angle is opposite to the rotating direction of the rolling cylinder 110, so that the brushing part 1212 can press the grass clippings 210 in contact with the brushing part 1212 towards the ground.

[0033] The rolling brush mechanism 100 for the grass removing device is applied to a grass removing device such as a mower 300. When the grass clippings 210 are cleaned, the rolling cylinder 110 rotates around its own axis, drives the brush cleaning piece 120 to rotate together with the rolling cylinder 110, and makes the brush cleaning piece 120 to sweep the grass clump 200. Since the brush cleaning piece 120 is provided with the at least one bending structure 121, and in the at least one bending structure 121, the included angle formed between the connecting part 1211 and the brushing part 1212 at the bending part 1215 is opposite to the rotating direction of the rolling cylinder 110, when the grass clump 200 is swept, the brush cleaning piece 120 has the brushing part 1212 which is bent and extends in the direction opposite to the rotating direction, can press the grass clippings 210 on the surface of the grass clump 200, reduces the lift generated by the brush cleaning piece 120 when leaving the grass surface, makes most of the grass clippings 210 to be beaten into the grass clump 200, and effectively improves the cleaning effect of the grass clippings 210.

[0034] It should be noted that the brush cleaning piece 120 has the at least one bending structure 121, and the emphasis is on the state of the structure on the brush cleaning piece 120, not the forming process of the bending structure 121 on the brush cleaning piece 120. The forming process of the bending structure 121 is not limited in the embodiment, for example, the bending structure 121 can be formed by an integral bending process, or can be combined by welding, clamping, screwing and the like, so that the brush cleaning piece 120 has the bending structure 121 in the designed state.

[0035] It should also be noted that the number of bending structures 121 can be one, two, or more. When there are two or more bending structures 121, it is only necessary to ensure that the bending direction of the brushing part 1212 in at least one bending structure 121 at the connecting part 1211 is opposite to the rotation direction of the roller 110. The bending direction of the other bending structures 121 is not limited. Of course, the brushing part 1212 formed by bending in the opposite direction to the rotation direction of the roller 110 must also have the function of pressing the grass clippings 210 towards the ground. That is, the brushing part 1212 bent in the opposite direction to the rotation direction should have a certain length and cannot be a small brushing part 1212 structure formed by slight bending. The specific length of the brushing part 1212 can be determined according to the actual size of the roller 110 and the cleaning brush 120, and is not specifically limited here.

[0036] Furthermore, the bend 1215 in this embodiment can be a fold point; it can be a bend in the structure; or it can be any segment of the structure connecting the connecting part 1211 and the brushing part 1212. Moreover, the angle formed by the connecting part 1211 and the brushing part 1212 at the bend 1215 should be understood as the angle formed by the intersecting distribution of the connecting part 1211 and the brushing part 1212. For ease of understanding, let's use... Figure 1 For example, the included angle in this embodiment is Figure 1 The angle represented by θ. Of course, when determining the included angle in this embodiment, the minor angle (i.e., greater than 0° and less than 180°) formed between the connecting part 1211 and the brushing part 1212 should be selected. Meanwhile, the opening direction of the included angle can be understood as the direction in which the included angle opens. For further understanding, a line can be drawn connecting the end of the connecting part 1211 away from the bend 1215 and the end of the brushing part 1212 away from the bend 1215. In this case, the opening direction of the included angle is: the direction from the bend 1215 to the line connecting the two ends within the included angle. Please continue to refer to... Figure 1 The opening direction of the included angle can be... Figure 1 The direction indicated by S in the middle. In addition, the first end 123 and the second end 124 can be understood as the two opposite endpoints of the cleaning brush 120; of course, they can also be understood as the two opposite end faces of the cleaning brush 120.

[0037] For details, please refer to Figure 1 and Figure 5 When there is only one bending structure 121, the cleaning brush 120 and the bending structure 121 can be considered as the same structure. That is, the brush moving part 1212 is connected to the roller 110 through the connecting part 1211.

[0038] Further, please refer to Figure 1A first tangent line 1213 is formed by making a tangent line at any point in at least one section of the brushing portion 1212. A second tangent line 1214 is formed by making a tangent line at any point in at least one section of the connecting portion 1211. The first tangent line 1213 and the second tangent line 1214 intersect with each other. Here, the "at least one section" should be understood as that there is at least one section along the length direction of the brushing portion 1212 and the connecting portion 1211.

[0039] Specifically, in the embodiment, the included angle θ between the first tangent line 1213 and the second tangent line 1214 is less than or equal to 90°, and at this time, the shape of the bending structure 121 is or approximately is L-shaped. The embodiment limits the angle between the first tangent line 1213 and the second tangent line 1214 to be less than 90°, so that the bending structure 121 is bent at an acute angle, thereby facilitating the brushing portion 1212 to better press the grass clippings 210 into the grass 200, so as to further improve the cleaning effect.

[0040] It should be noted that when the brushing portion 1212 and the connecting portion 1211 are both linear structures, the first tangent line 1213 is parallel to the brushing portion 1212, and the second tangent line 1214 is parallel to the connecting portion 1211. When the brushing portion 1212 and the connecting portion 1211 are both arc-shaped structures, a point on the brushing portion 1212 and a point on the connecting portion 1211 can be taken to form the first tangent line 1213 and the second tangent line 1214 respectively, as long as the included angle between the first tangent line 1213 and the second tangent line 1214 is less than 90°.

[0041] Further, please refer to Figure 1 and Figure 5 , the brushing portion 1212 is bent on the connecting portion 1211 in a linear angle or arc curvature manner. In this way, the brushing portion 1212 and the connecting portion 1211 can be arranged at an angle or can be arranged in an arc shape. For example, the shape of the bending structure 121 can be L-shaped, V-shaped, S-shaped, zigzag-shaped or squiggle-shaped, etc. Of course, it can also be an irregular arc structure.

[0042] In one embodiment, please refer to Figure 3 , the roller 110 is provided with a mounting position 112. At least one cleaning brush 120 is arranged on the same mounting position 112, that is, at least one cleaning brush 120 can be mounted on the same mounting position 112, so as to ensure the cleaning effect of the roller brush mechanism 100.

[0043] It should be noted that the mounting position 112 on the roller 110 can be designed as a hole or groove structure, or as a convex or flat structure, etc. When the mounting position 112 is designed as a hole or groove structure, at least one cleaning brush 120 is implanted in the hole or groove.

[0044] Specifically, please refer to Figure 3The mounting hole 1121 is arranged in the mounting position 112.

[0045] Optionally, the mounting manner of the brush cleaning member 120 on the mounting position 112 can be adhesion, implantation, welding, threaded connection, clamping, or the like.

[0046] Further, please refer to Figure 3 One or two brush cleaning members 120 are arranged on the same mounting position 112, that is, the single or double brush cleaning member 120 design is adopted on the same mounting position 112, so that the grass entanglement phenomenon caused by too many brush cleaning members 120 can be effectively reduced while ensuring sufficient cleaning force.

[0047] In an embodiment, please refer to Figure 1 With Figure 5 The brush cleaning member 120 is a plurality of brush cleaning members. The plurality of brush cleaning members 120 are arranged along the circumferential direction of the roller 110, so that the plurality of brush cleaning members 120 can act on the surface of the grass clump 200 in turn as the roller 110 rotates, so that the grass clippings 210 can be effectively pressed into the grass clump 200, and a better cleaning effect can be achieved.

[0048] It should be noted that when the brush cleaning member 120 is arranged along the circumferential direction of the roller 110, the distribution density of the brush cleaning member 120 can be determined according to actual needs and the size of the roller 110. For example, when two adjacent brush cleaning members 120 are arranged, the two brush cleaning members 120 can be closely arranged without contacting each other.

[0049] In an embodiment, please refer to Figure 2 With Figure 6 The brush cleaning member 120 is a plurality of brush cleaning members. The plurality of brush cleaning members 120 are arranged along the axial direction of the roller 110 to form at least one row of brush cleaning assemblies 122, so that the plurality of brush cleaning members 120 are arranged in a row along the axial direction of the roller 110 to improve the cleaning ability of the axial direction of the roller 110, thereby facilitating the improvement of the cleaning efficiency of the brush rolling mechanism 100.

[0050] It should be noted that when the plurality of brush cleaning members 120 are arranged along the axial direction of the roller 110, the plurality of brush cleaning members 120 can be arranged in a spiral manner, or can be arranged in a straight line manner, or the like.

[0051] Of course, please refer to Figure 4 In other embodiments, the brush cleaning member 120 can also be arranged along the axial direction of the roller 110, that is, the brush cleaning member 120 is designed in a plate shape or a sheet shape.

[0052] Further, in the embodiment, the cleaning brush 120 is arranged in the circumferential direction of the roller 110 and in the axial direction of the roller 110. The cleaning brush assemblies 122 arranged in the axial direction of the roller 110 are multiple. The multiple cleaning brush assemblies 122 are arranged in the circumferential direction of the roller 110.

[0053] In one embodiment, referring to Figure 3 , the cleaning brush 120 is arranged on the barrel 111 of the roller 110. The barrel 111 is understood as the outer surface of the roller 110 surrounding the axis of the roller 110.

[0054] In one embodiment, referring to Figure 1 and Figure 7 , a mower 300 includes a machine body 310 and the roller brush mechanism 100 for the weeding device in any of the above embodiments. The machine body 310 is provided with a mowing part having a cutting function. The roller 110 is rotatably arranged on the machine body 310. The roller brush mechanism 100 is used to press the grass clippings 210 generated by the mowing part to the ground.

[0055] The above-described mower 300 uses the above roller brush mechanism 100 for the weeding device. During the mowing process, part of the grass clippings 210 will remain on the surface of the grass clump 200 after the mowing part cuts the grass clump 200. Therefore, the roller 110 is driven to rotate around its own axis, so that the cleaning brush 120 rotates with the roller 110, thereby causing the cleaning brush 120 to push away the grass clump 200. Since the cleaning brush 120 has at least one bending arrangement to form a bending structure 121, and in at least one bending structure 121, the brushing part 1212 is arranged on the connecting part 1211 in a direction opposite to the rotation direction of the roller 110, when the grass clump 200 is pushed away, the cleaning brush 120 has a brushing part 1212 extending in a direction opposite to the rotation direction, which can press the grass clippings 210 on the surface of the grass clump 200 to reduce the lift generated by the cleaning brush 120 when it leaves the grass surface, so that most of the grass clippings 210 are pressed into the grass clump 200, thereby effectively improving the cleaning effect of the grass clippings 210.

[0056] It should be noted that the cooperation sequence between the mowing part and the rolling brush mechanism 100 can be that the rolling brush mechanism 100 runs to press the grass clippings 210 into the grass clump 200 only after the mowing part cuts all the grass; or the rolling brush mechanism 100 runs to press the grass clippings 210 into the grass clump 200 after the mowing part cuts part of the grass; or the mowing part and the rolling brush mechanism 100 run synchronously, that is, the mowing part cuts the grass and the rolling brush mechanism 100 cleans the grass clippings 210 at the same time. In addition, in order to meet the requirement that the rolling brush mechanism 100 runs to press the grass clippings 210 into the grass clump 200 after the mowing part cuts the grass, a time sequence control program can be programmed to control the running time of the mowing part and the rolling brush mechanism 100. At this time, the positional relationship between the mowing part and the rolling brush mechanism 100 can be set at will. Of course, the position of the mowing part and the rolling brush mechanism 100 on the machine body 310 can also be arranged to meet the requirements of mowing and cleaning.

[0057] It should also be noted that the number of the rollers 110 can be one or more. When the number of the rollers 110 is one, it can rotate forward or reverse on the machine body 310. For details, please refer to Figure 7 (a) and Figure 7 (b).

[0058] Further, please refer to Figure 7 , the lawn mower 300 can move and work autonomously in the working area defined by the boundary; the machine body 310 has a walking module along the advancing direction. The mowing part and the rollers 110 are distributed along the advancing direction on the machine body 310. Therefore, when the machine body 310 moves along the advancing direction, the mowing part is at the front end of the rollers 110. At this time, the mowing part acts on the grass clump 200 before the rollers 110 to realize the function of cutting the grass first. With the movement of the machine body 310, the mowing part moves away from the grass clump 200 area, and the rollers 110 enter the cut grass clump 200 area, use the brush cleaning piece 120 to push away the grass clump 200, and press the grass clippings 210 into the grass clump 200 to realize effective cleaning effect. In this way, the position relationship between the mowing part and the rollers 110 is used to effectively realize the synchronization of mowing and cleaning, and greatly improve the working efficiency of the lawn mower 300.

[0059] It should be noted that the advancing direction of the machine body 310 should be understood as at least including forward and backward. For example: when the machine body 310 is in forward motion, the advancing direction is the forward direction; when the machine body 310 is in backward motion, the advancing direction is the backward direction.

[0060] It should be noted that the "boundary" of the embodiment can be a virtual boundary, such as a boundary contour formed by the edge of the grass 200; or a physical boundary, such as a boundary formed by a fence, a hedge, a wall, or the like. In addition, the mower 300 further comprises an energy module, an image acquisition module, and a control module. The energy module is used to provide energy for the mower 300. The image acquisition module is used to acquire image information near the mower 300, and to control the movement and / or work of the mower according to the acquired image information. The control module is electrically connected to the walking module, the mowing part, and the image acquisition module, and is used to control the movement and / or work of the mower in the working area. The mower 300 has at least two working modes: a mowing mode and a monitoring mode. The mower 300 identifies the boundary of the working area and performs cutting work in the mowing mode. The mower 300 acquires image information near the mower 300 and determines whether there is an anomaly in the monitoring mode. The control module at least partially switches the first working position and the second working position according to the switching of the mowing mode and the monitoring mode. The mowing mode corresponds to the first working position; and the monitoring mode corresponds to the second working position.

[0061] Optionally, the control module can control the walking module to move according to the work requirements, such as a work path or a preset trajectory, etc.

[0062] Further, please refer to Figure 8 The plurality of rollers 110 are arranged along the advancing direction, and the rotation directions of any two adjacent rollers 110 are the same or opposite. At this time, the rollers 110 have four rotation states on the machine body 310. For the convenience of distinguishing and understanding, the clockwise direction is defined as reverse rotation, and the counterclockwise direction is defined as forward rotation. Meanwhile, in the two adjacent rollers 110, the roller 110 close to the end of the machine body 310 is defined as a front roller 110, and the roller 110 away from the end of the machine body 310 is defined as a rear roller 110. At this time, the four rotation modes are: one, please refer to Figure 8 (a), in the two adjacent rollers 110, the front roller 110 rotates forward, and the rear roller 110 rotates forward; two, please refer to Figure 8 (b), in the two adjacent rollers 110, the front roller 110 rotates forward, and the rear roller 110 rotates reversely; three, please refer to Figure 8 (c), in the two adjacent rollers 110, the front roller 110 rotates reversely, and the rear roller 110 rotates reversely; four, please refer to Figure 8 (d), in the two adjacent rollers 110, the front roller 110 rotates forward, and the rear roller 110 rotates forward.

[0063] In one embodiment, please refer to Figure 7The mower 300 comprises a suspension device 320. The roller 110 is mounted on the machine body 310 by the suspension device 320. Thus, by using the suspension device 320, effective buffering and shock absorption are achieved, and the roller 110 is prevented from being easily broken due to rigid installation on the machine body 310 during cleaning.

[0064] It should be noted that the suspension device 320 is a force transmission connection device between the machine body 310 and the roller 110, and its function is to transmit the force and torque between the roller 110 and the machine body 310, buffer the impact force transmitted from the grass 200 to the machine body 310, and attenuate the vibration caused thereby. Since the suspension device 320 is not the object to be improved in the embodiment, its specific structure can be directly referred to the existing documents and existing products, and will not be described here.

[0065] In one embodiment, the mower 300 further comprises a roller height adjusting device. The roller height adjusting device is configured to adjust the height of the roller 110 when the required cutting height of the grass 200 changes, so that the height of the roller 110 is adapted to the height of the mowing part. For example, the cutting height and the height of the roller 110 have a corresponding relationship table, and the roller height adjusting device can determine the height of the roller 110 corresponding to the cutting height according to the table, so as to achieve a better grass crushing effect. The corresponding relationship table can be determined according to the actual size of the equipment.

[0066] It should be noted that the suspension device and the roller height adjusting device can be the same structure, for example, the suspension device is a telescopic mechanism, that is, it can be installed and adjusted in height, for example, but not limited to, a telescopic rod, a spring, an adjusting screw, etc. Of course, it can also be two different structures, for example, the height adjusting device is a device connected to the roller and capable of promoting the roller to swing to adjust the height. At the same time, the "cutting height" of the embodiment should be understood as the height of the grass 200 after cutting, which can be determined by the actual requirement of the user. When the cutting height changes, the height position of the mowing part on the machine body 310 should also change accordingly, so that the mowing part can cut the grass 200 to the required height. In addition, the roller height adjusting device can adjust the height of the roller 110 alone; or the height of the roller 110 and the height of the mowing part can be adjusted synchronously when the roller height adjusting device adjusts the height of the roller 110.
