Description

Technical Field

[0001] This utility model relates to the field of unmanned vehicle technology, and in particular to a roller brush mounting mechanism and an unmanned sweeper. Background Technology

[0002] As an essential tool for ensuring environmental hygiene, the performance and ease of use of cleaning equipment directly impact the efficiency and quality of cleaning work. Among these components, the roller brush, a core element of the cleaning equipment, plays a crucial role in removing litter from the ground. Height-adjustable roller brushes, due to their ability to better adapt to different surface smoothness and materials, thus improving cleaning effectiveness, are gradually becoming the mainstream demand in the market.

[0003] In existing technologies, roller brushes are typically connected to the actuator of the adjustment mechanism using methods such as welding during installation. This provides a relatively stable connection, ensuring that the roller brush will not easily loosen or shift during cleaning, thus guaranteeing the stability and reliability of the cleaning process. Under the action of the adjustment mechanism, the roller brush can be adjusted up and down according to the height and conditions of different ground surfaces to achieve the best cleaning effect.

[0004] However, disassembling the roller brush becomes extremely difficult when it becomes worn, damaged, or requires cleaning and maintenance. Since welding is an irreversible connection method, removing the roller brush from the adjustment mechanism often requires specialized cutting tools. This not only increases the difficulty and time cost of disassembly but may also cause damage to the adjustment mechanism and the roller brush itself. Utility Model Content

[0005] The purpose of this utility model is to provide an installation mechanism for roller brushes and an unmanned sweeper, which solves the problem that when roller brushes are fixedly installed, disassembly is difficult and maintenance time and cost are high when they need to be disassembled and maintained later.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this application provides a mounting mechanism for a roller brush, used to movably connect a roller brush to a bracket, comprising:

[0008] A rotating shaft is rotatably connected to the bracket and is arranged parallel to the roller shaft of the brush.

[0009] The connecting arm has one end rotatably connected to the roller shaft of the roller brush via a bearing, and the connecting arm is detachably connected to the roller shaft of the roller brush via a first locking component. The other end is detachably connected to the rotating shaft via a second locking component.

[0010] Optionally, the first locking component includes:

[0011] A pressure block is pressed on one side of the bearing and the roller end face of the brush;

[0012] A first locking member is inserted through the pressure block and detachably connected to the roller of the brush, and the first locking member abuts against the other side of the pressure block.

[0013] Optionally, the first locking component further includes:

[0014] A first pressure cap is disposed on the side of the connecting arm and covers the first locking member.

[0015] Optionally, the first pressure cap is circumferentially spaced with a plurality of first fasteners, which pass through the first pressure cap and are detachably connected to the connecting arm.

[0016] Optionally, the second locking component includes:

[0017] A pressure sleeve passes through the connecting arm and is sleeved on the rotating shaft. The outer side of the pressure sleeve is engaged with the connecting arm, and the inner side of the pressure sleeve is engaged with the rotating shaft.

[0018] The second locking member is inserted through the pressure sleeve and detachably connected to the rotating shaft, and the second locking member abuts against the inner wall of the pressure sleeve.

[0019] Optionally, the second locking component further includes:

[0020] The second pressure cap is disposed on the end face of the pressure sleeve and covers the second locking member.

[0021] Optionally, a plurality of second fasteners are distributed at axial intervals along the second cover, and the second fasteners pass through the second cover and are detachably connected to the cover.

[0022] Optionally, the roller of the brush passes through the bearing of the connecting arm, and a transmission wheel connected to the first drive assembly is provided on the outer side of the connecting arm. The second locking assembly is provided on the transmission wheel and is detachably connected to the roller of the brush.

[0023] Optionally, the connecting arm has multiple strip-shaped holes.

[0024] Secondly, this application provides an unmanned cleaning vehicle, which includes:

[0025] The bracket has a first roller brush and a second roller brush distributed at intervals along its length. The first roller brush is movably connected to the bracket via a roller brush mounting mechanism as described in the first aspect, and the second roller brush is rotatably connected to the bracket.

[0026] The beneficial effects of this utility model are:

[0027] Firstly, by setting up a rotating shaft and a connecting arm, before installing the roller brush, the rotating shaft is rotatably connected to the bracket. A connecting arm is installed at the end of the rotating shaft and connected to the roller brush's roller shaft via a bearing. Then, a first locking component detachably connects the roller brush and the connecting arm together. The other end of the connecting arm is detachably connected to the rotating shaft via a second locking component. This allows the roller brush to move by rotating the connecting arm around the rotating shaft, adjusting the roller brush height for efficient cleaning. When maintenance is required, the first and second locking components can be quickly disassembled, allowing for rapid removal of the connecting arm and roller brush disassembly. Therefore, this roller brush installation mechanism allows for quick overall installation and disassembly via the first and second locking components, effectively reducing installation and disassembly difficulty, saving time, and minimizing the possibility of damaging the roller brush during installation and disassembly.

[0028] Secondly, when the unmanned sweeper is performing sweeping operations, the dual-brush cleaning of the first and second rollers can effectively improve sweeping efficiency. At the same time, the first roller is installed through the aforementioned roller brush installation mechanism, which can also be quickly disassembled and installed during subsequent maintenance and repair, thereby effectively reducing the difficulty of maintenance and repair and improving work efficiency.

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 6 As shown, this utility model provides a roller brush mounting mechanism and an unmanned sweeper.

[0042] The roller brush mounting mechanism is used to movably connect the roller brush to the bracket 10, and includes a rotating shaft 1 and a connecting arm 2. The rotating shaft 1 is rotatably connected to the bracket 10 and is arranged parallel to the roller 1011 of the roller brush; one end of the connecting arm 2 is rotatably connected to the roller 1011 of the roller brush through a bearing 21, and the connecting arm 2 and the roller 1011 of the roller brush are detachably connected through a first locking component 3, and the other end is detachably connected to the rotating shaft 1 through a second locking component 4.

[0043] By setting up a rotating shaft 1 and a connecting arm 2, before installing the roller brush, the rotating shaft 1 is rotatably connected to the bracket 10. The connecting arm 2 is set at the end of the rotating shaft 1 and connected to the roller brush's roller shaft 1011 via a bearing 21. Then, the roller shaft 1011 and the connecting arm 2 are detachably connected together via a first locking component 3. The other end of the connecting arm 2 is detachably connected to the rotating shaft 1 via a second locking component 4. Thus, the roller brush can be moved by rotating the connecting arm 2 around the rotating shaft 1 to adjust the height of the roller brush and achieve efficient cleaning. When maintenance is required, the first locking component 3 and the second locking component 4 can be quickly disassembled, allowing for the rapid removal of the connecting arm 2 and the roller brush. Therefore, this roller brush installation mechanism allows for quick overall installation and disassembly via the first locking component 3 and the second locking component 4, effectively simplifying the installation and disassembly process, saving time, and reducing the possibility of damaging the roller brush during installation and disassembly.

[0044] Specifically, the support 10 is formed by multiple plate-like structures. The roller brush is located on the lower side of the support 10, while the rotating shaft 1 is located on the upper side of the support 10. Both ends of the rotating shaft 1 extend through the two side walls of the support 10. A connecting arm 2 can be provided at each end of the rotating shaft 1. The connecting arm 2 is elongated and has multiple slotted holes 22 to make the overall weight of the connecting arm 2 lighter and easier to drive the connecting arm 2 to swing. A through hole is provided at the end of the connecting arm 2 near the roller 1011 of the roller brush to install a bearing 21. The inner ring of the bearing 21 is for the roller 1011 to pass through and is fixedly connected to the roller 1011 so that the roller 1011 can rotate. A first locking member 32 is provided on the outside of the connecting arm 2. The first locking member 32 is partially inserted into the roller 1011 and forms a detachable connection with the roller 1011, such as a threaded connection or a snap-fit, so that the connecting arm 2 and the roller 1011 of the roller brush can be detachably connected.

[0045] Optionally, the first locking assembly 3 includes a pressure block 31 and a first locking member 32. One side of the pressure block 31 is pressed against the bearing 21 and the end face of the roller 1011 of the roller brush; the first locking member 32 passes through the pressure block 31 and is detachably connected to the roller 1011 of the roller brush, and the first locking member 32 abuts against the other side of the pressure block 31.

[0046] Specifically, the pressure block 31 is disc-shaped and abuts against the inner ring of the bearing 21. A first locking member 32 is provided in the middle of the pressure block 31. The first locking member 32 can be a bolt. In this case, a threaded hole is opened on the end face of the roller 1011. After the bolt passes through the pressure block 31, it is screwed into the threaded hole, and the bolt head presses against the pressure block 31 to press the pressure block 31 tightly against the inner ring of the bearing 21. The outer ring of the bearing 21 is fixedly connected to the connecting arm 2, thereby forming a detachable connection between the connecting arm 2 and the roller 1011. In other embodiments, the first locking member 32 can also be a plug-in structure such as a pin. In this case, a plug hole is opened on the end face of the roller 1011, and a locking is formed by the cooperation of a protrusion and groove structure, which can lock the first locking member 32 and the roller 1011 together. On the side of the first locking member 32 that does not pass through the pressure block 31, a protrusion or other structure can also be provided to press against the pressure block 31 to press the pressure block 31 tightly against the inner ring of the bearing 21.

[0047] Optionally, the first locking assembly 3 further includes a first pressure cap 33. The first pressure cap 33 is disposed on the side of the connecting arm 2 and covers the first locking member 32.

[0048] Specifically, a first pressure cover 33 is provided on the side of the pressure block 31 away from the connecting arm 2. The center of the first pressure cover 33 is recessed to form a clearance space to accommodate the first locking member 32 and the pressure block 31. The edge of the first pressure cover 33 can be snapped, screwed or bolted to the connecting arm 2 or the outer ring of the bearing 21 to form a detachable connection. Thus, after the first locking member 32 is installed, the first pressure cover 33 is provided to seal the first locking member 32 inside, so as to prevent garbage and other debris from adhering to the first locking member 32 during cleaning and affecting the installation and removal of the first locking member 32.

[0049] In this embodiment, to facilitate the assembly and disassembly of the first pressure cover 33, a plurality of first fasteners 34 are circumferentially spaced on the first pressure cover 33. The first fasteners 34 pass through the first pressure cover 33 and are detachably connected to the connecting arm 2. The first fasteners 34 can be bolts or pins. When bolts are used, the first pressure cover 33 has through holes for the bolts to pass through, and threaded holes are provided on the outer ring of the connecting arm 2 or the bearing 21 for threaded connection with the bolts. When pins are used, insertion holes are provided on both the first pressure cover 33 and the connecting arm 2, and the insertion holes are interference-fitted with the pins. The specific type of the first fasteners 34 can be designed according to the actual assembly and disassembly difficulty, and this application does not limit it.

[0050] Optionally, the roller 1011 of the brush passes through the bearing 21 of the connecting arm 2, and a transmission wheel 5 connected to the first drive assembly 103 is provided on the outer side of the connecting arm 2. The first locking assembly 3 is provided on the transmission wheel 5 and is detachably connected to the roller 1011 of the brush.

[0051] Specifically, a connecting arm 2 is provided at each end of the rotating shaft 1. A transmission wheel 5 is provided on the outer side of one of the connecting arms 2. At this time, the roller shaft 1011 of the brush passes through the bearing 21 of the connecting arm 2 on this side. The transmission wheel 5 is coaxially and fixedly connected to the roller shaft 1011 of the brush. The first locking component 3 is directly provided on the transmission wheel 5, and a washer is also provided between the transmission wheel 5 and the connecting arm 2 to separate the transmission wheel 5 from the connecting arm 2, so as to avoid friction between the transmission wheel 5 and the connecting arm 2 during movement. At this time, the first locking component 32 directly connects the transmission wheel 5 and the roller shaft 1011 together. The inner side of the transmission wheel 5 abuts against the inner ring of the bearing 21 through the washer to limit the connecting arm 2. During disassembly, only the first locking component 32 needs to be removed to remove the transmission wheel 5, and at the same time, the locking of the connecting arm 2 can be released to complete the disassembly.

[0052] The end of the connecting arm 2 away from the roller 1011 has a through hole for engaging with the rotating shaft 1. The connecting arm 2 and the rotating shaft 1 are detachably connected by a first locking component 3. The first locking component 3 can be a sleeve-shaped structure, which is sleeved on the rotating shaft 1 and inserted into the connecting arm 2, thereby making the connecting arm 2 and the rotating shaft 1 detachably connected. Alternatively, the first locking component 3 can be a block-shaped component disposed on the connecting arm 2, which can be inserted into the rotating shaft 1, thereby making the connecting arm 2 and the rotating shaft 1 detachably connected.

[0053] Optionally, the second locking assembly 4 includes a pressure sleeve 41 and a second locking member 42. The pressure sleeve 41 passes through the connecting arm 2 and is sleeved on the rotating shaft 1. The outer side of the pressure sleeve 41 is engaged with the connecting arm 2, and the inner side of the pressure sleeve 41 is engaged with the rotating shaft 1. The second locking member 42 passes through the pressure sleeve 41 and is detachably connected to the rotating shaft 1. The second locking member 42 abuts against the inner wall of the pressure sleeve 41.

[0054] Specifically, one end of the pressure sleeve 41 has a insertion hole for the rotating shaft 1 to be inserted, and the other end has a mounting hole for the second locking member 42 to be inserted. The diameter of the mounting hole is smaller than that of the insertion hole, and a connecting hole communicating with the insertion hole is formed on the bottom wall of the mounting hole. The diameter of the connecting hole is smaller than that of the mounting hole, so that part of the second locking member 42 can pass through and be inserted into the rotating shaft 1. The structure of the second locking member 42 can refer to that of the first locking member 32, and it can be a bolt or a pin, etc., which will not be described in detail here. The outer wall of the pressure sleeve 41 is stepped, and its stepped surface abuts against the side of the connecting arm 2, thereby forming a connection with the connecting arm 2. The pressure sleeve 41 and the connecting arm 2 can be rotatably connected or fixedly connected, such as by welding or bonding, which can be designed according to the swing requirements of the connecting arm 2.

[0055] When it is necessary to lock the connecting arm 2 and the rotating shaft 1, the connecting arm 2 and the rotating shaft 1 can be detachably connected by installing the pressure sleeve 41 and the second locking member 42. When it is necessary to disassemble, the second locking member 42 can be removed from the pressure sleeve 41 to quickly separate the pressure sleeve 41, the connecting arm 2 and the rotating shaft 1, thereby quickly completing the disassembly.

[0056] To protect the second locking member 42, the second locking assembly 4 also includes a second pressure cover 43. The second pressure cover 43 is disposed on the end face of the pressure sleeve 41 and covers the second locking member 42.

[0057] Specifically, a second pressure cap 43 is provided on the end face of the pressure sleeve 41 away from the connecting arm 2. The side of the second pressure cap 43 fits against the end face of the pressure sleeve 41 and closes the mounting hole. The second pressure cap 43 and the pressure sleeve 41 are detachably connected, such as by snap-fit ​​or screw connection. In this embodiment, multiple second fasteners 44 are distributed circumferentially around the second pressure cap 43. The second fasteners 44 pass through the second pressure cap 43 and are detachably connected to the pressure sleeve 41. The second fasteners 44 are similar to the first fastener 34 and can also be bolts. In this case, a through hole is opened on the second pressure cap 43, and a threaded hole is opened on the end face of the pressure sleeve 41. By installing a bolt in the through hole and screwing it into the threaded hole, the second pressure cap 43 can be quickly installed onto the pressure sleeve 41. When disassembly is required, the second pressure cap 43 can be separated from the pressure sleeve 41 by quickly disassembling the second fastener 44. In other embodiments, the second fastener 44 can also be a pin, and its setting method can refer to the first fastener 34, which will not be described again in this application.

[0058] The unmanned sweeper includes a support frame 10. The support frame 10 has a first roller brush 101 and a second roller brush 102 spaced apart along its length. The first roller brush 101 is movably connected to the support frame 10 through a roller brush mounting mechanism as described above, and the second roller brush 102 is rotatably connected to the support frame 10.

[0059] Specifically, the first roller brush 101 is driven by the first drive assembly 103 to rotate toward the second roller brush 102, and the second roller brush 102 is driven by the second drive assembly 104 to rotate toward the first roller brush 101, so as to form a dual roller brush mode during the cleaning operation, thereby efficiently cleaning up the garbage.

[0060] When the unmanned sweeper is performing sweeping operations, the dual-brush cleaning of the first roller brush 101 and the second roller brush 102 can effectively improve the sweeping efficiency. At the same time, the first roller brush 101 is installed through the aforementioned roller brush installation mechanism, which can also be quickly disassembled and installed during subsequent maintenance and repair, thereby effectively reducing the difficulty of maintenance and repair and improving work efficiency.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
