Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a sweeping brush mechanism with an adjustable outward extension angle. Background Technology

[0002] With the improvement of living standards, people's demand for a beautiful environment is also increasing. Nowadays, sweepers are ubiquitous in city streets and alleys, maintaining urban cleanliness. The sweeping brush, as one of the important working devices of the sweeper, is mainly responsible for cleaning along edges and collecting garbage. To ensure the normal driving and operation of the sweeper, the brush needs to retract inwards when the sweeper is moving and extend outwards when the sweeper is working. To meet the operational requirements of the brush, the current mainstream approach is to use the extension and retraction of a cylinder to achieve the extension and retraction of the brush. Similarly, the extension and retraction of the cylinder is used to raise and lower the brush. Structurally, springs are used to prevent the brush from impacting. However, since the stroke of the cylinder is fixed, the angle of the brush's outward extension is fixed, and therefore the cleaning width is also fixed. Due to different working conditions, the cleaning width of the brush needs a certain adjustment range to more flexibly adapt to various working environments. Because the angle of the brush's outward extension directly determines the cleaning width, it is necessary to design a sweeping brush mechanism with an adjustable extension angle. At the same time, the brush must also have a certain anti-collision capability. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sweeping brush mechanism with an adjustable outward extension angle, which realizes stepless adjustment of the outward extension angle of the sweeping brush, and ultimately achieves flexible change of the cleaning width of the side brush.

[0004] Specifically, this utility model discloses a sweeping mechanism with an adjustable outward extension angle, comprising:

[0005] The fixing component includes a fixing frame, on the upper side of which an extension drive is mounted;

[0006] An angle adjustment assembly includes a rotary cylinder mounted on the end of a fixed frame, wherein a limiting boss is connected to the output end of the rotary cylinder;

[0007] A brush sweeping device includes a brush frame and a brush assembly. A fixed base is provided at the end of the brush frame. The fixed base is rotatably connected to the fixed frame. A limiting block is fixed on the lower side of the fixed base. The extension drive drives the brush frame to rotate. The limiting boss cooperates with the limiting block to control the outward extension angle of the brush frame.

[0008] The advantages of adopting the above technical solution are that it realizes the stepless adjustment of the outward extension angle of the sweeping brush, that is, the sweeping width of the sweeper is adjustable. At the same time, when the sweeper is working, the extension drive retracts and the sweeping brush extends outward. If the sweeping brush is hit at this time, it will drive the extension drive to extend and the sweeping brush will retract, which will avoid the impact. The sweeping brush mechanism is flexible, stable and reliable, and the overall structure is compact with high space utilization.

[0009] Furthermore, the sweeping brush assembly includes: a sweeping brush, a mounting base, a rotary motor, and a sweeping brush lifting cylinder. The sweeping brush is connected to the rotary motor, the mounting base is fixed to the end of the sweeping brush frame away from the fixed base, the rotary motor is mounted on the mounting base, and the sweeping brush lifting cylinder is hinged to the fixed base.

[0010] The advantage of adopting the above technical solution is that a rotatable brush assembly is set to realize the cleaning action, and a brush lifting cylinder is set to realize the height position control of the brush, which is suitable for different cleaning situations.

[0011] Furthermore, the brush assembly also includes an adjustable screw, the two ends of which are hinged to the fixed base and the mounting base, respectively.

[0012] The advantage of adopting the above technical solution is that by changing the length of the adjusting screw, the installation angle of the mounting base is changed, thereby changing the cleaning angle of the brush and making it suitable for different usage environments.

[0013] Furthermore, one end of the fixing frame is fixed to the vehicle frame, and the other end is a non-fixed end, which is equipped with an upper seat plate, a lower seat plate, and a fixing cylinder located between the upper seat plate and the lower seat plate. The rotary cylinder is installed in the fixing cylinder, and the upper seat plate and the lower seat plate are hinged to the fixing frame.

[0014] The advantages of adopting the above technical solution are that the upper and lower base plates are designed to connect with the fixed base, allowing the fixed base to rotate relative to it. At the same time, the fixed cylinder is designed to install the rotary cylinder and also serves a protective function, ensuring that the rotary cylinder is not subjected to external impact and effectively extending its service life.

[0015] Furthermore, the side of the fixed base is provided with a protruding lug, which is hinged to the extended end of the extension drive member, and the extension drive member is hinged to the fixed frame.

[0016] The advantage of adopting the above technical solution is that the protruding support ear facilitates the connection of the output end of the extension drive component. When the output end of the extension drive component retracts, it drives the protruding support ear to rotate, which in turn drives the brush frame to extend outward and change the angle. Both ends of the extension drive component are hinged, so that it will not get stuck during the process of driving the brush frame to move.

[0017] Furthermore, the rotary cylinder is equipped with an encoder.

[0018] The advantage of adopting the above technical solution is that the encoder is used to control the rotation angle of the rotary cylinder, further control the position of the limit boss, thereby limiting the extension angle of the sweeping disc, realizing the adjustment of the extension angle of the sweeping disc, and ultimately realizing the flexible change of the cleaning width of the side brush.

[0019] Furthermore, a spray frame is installed on the upper side of the mounting base, and multiple spray nozzles are provided on the spray frame.

[0020] The advantage of adopting the above technical solution is that the spray rack and spray head are set up to spray water during the cleaning process, reduce dust, and protect the environment.

[0021] Furthermore, the brush holder includes a connecting rod, the two ends of which are hinged to the fixed seat and the mounting seat, the brush lifting cylinder is hinged to the fixed seat, and its extended end is hinged to the connecting rod.

[0022] The advantage of adopting the above technical solution is that the connecting rod is used to connect the mounting base and the fixed base, and the hinged setting allows the angle of the connecting rod to change under the drive of the brush lifting cylinder, so as to raise and lower the brush and change the position of the brush.

[0023] Furthermore, the extension drive is a cylinder, which is arranged along the fixed frame.

[0024] The advantage of adopting the above technical solution is that when the sweeper is working, the cylinder piston rod retracts, driving the sweeping brush to extend outward for operation. If the sweeping brush encounters an impact during operation, the cylinder piston rod will extend outward, driving the sweeping brush to retract. The pneumatic resistance is used to absorb the impact force and protect the sweeping brush from damage. Compared with the traditional structure that adds springs and other measures, the structure is simpler, more reliable and stable.

[0025] Furthermore, the spray frame includes two arc-shaped spray pipes that are connected to each other and are provided with a water inlet.

[0026] The advantage of adopting the above technical solution is that the two arc-shaped spray pipes ensure installation strength and uniform water output, and the inlet is set to connect the inlet pipe. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] like Figure 1-5 As shown, this utility model discloses a sweeping mechanism with an adjustable outward extension angle, comprising:

[0037] The fixing component includes a fixing frame 1, on the upper side of which an extension drive member 11 is mounted;

[0038] An angle adjustment assembly includes a rotary cylinder 2 installed at the end of the fixed frame 1. The output end of the rotary cylinder 2 is connected to a limiting boss 21. When the rotary cylinder 2 rotates, it causes the position of the limiting boss 21 to change.

[0039] The brushing device includes a brush frame 3 and a brush assembly 4. A fixed seat 31 is provided at the end of the brush frame 3. The fixed seat 31 is rotatably connected to the fixed frame 1. A limiting block 32 is fixed on the lower side of the fixed seat 31. The extension drive member 11 drives the brush frame 3 to rotate. The limiting boss 21 restricts the position of the limiting block 32 and controls the outward extension angle of the brush frame 3.

[0040] The advantage of adopting the above technical solution is that it realizes the stepless adjustment of the outward extension angle of the sweeping brush 41, that is, the sweeping width of the sweeper is adjustable. At the same time, when the sweeper is working, the extension drive 11 retracts and the sweeping brush 41 extends outward. If the sweeping brush 41 is hit at this time, it will drive the extension drive 11 to extend and the sweeping brush 41 will retract, which will avoid the impact. The sweeping brush 41 mechanism is flexible, stable and reliable, and the overall structure is compact with high space utilization.

[0041] In some implementations, the sweeping brush assembly 4 includes: a sweeping brush 41, a mounting base 42, a rotary motor 43, and a sweeping brush lifting cylinder 44. The sweeping brush 41 is connected to the rotary motor 43, which drives the sweeping brush 41 to rotate. The installation and connection method between the sweeping brush 41 and the rotary motor 43 is existing technology. The mounting base 42 is fixed to the end of the sweeping brush frame 3 away from the fixed base 31. The fixed base 31 has a side plate and a flat plate. The flat plate has a mounting hole in the middle for mounting the rotary motor 43. The side plate is welded to the flat plate and fixed to the sweeping brush frame with screws. The sweeping brush lifting cylinder 44 is hinged to the fixed base 31. The rotatable sweeping brush assembly 4 realizes the sweeping action, and the sweeping brush lifting cylinder 44 realizes the height position control of the sweeping brush 41, which is suitable for different cleaning environments.

[0042] Furthermore, the brush holder 3 includes a connecting rod 33, and a connecting plate 45 is also installed on the side of the mounting base 42. The connecting plate 45 is connected and fixed to the mounting base 42 by screws. The two ends of the connecting rod 33 are hinged to the fixed base 31 and the mounting base 42 to form the overall structure of the brush holder. The main body of the brush lifting cylinder 44 is hinged to the fixed base 31, and its extended end is hinged to the connecting rod 33.

[0043] Furthermore, the sweeping brush assembly 4 also includes an adjustable screw 5. This adjustable screw 5 comprises two threaded rods and a sleeve. The sleeve has threads on its inner side, with the threads at both ends turning in opposite directions. The two threaded rods extend into both ends of the sleeve and are locked by nuts. When the length needs to be changed, simply loosen the nuts and then change the extension length of the two threaded rods to change the overall length of the adjustable screw 5. The two ends of the adjustable screw 5 are hinged to the fixed base 31 and the mounting base 42, respectively. By changing the length of the adjustable screw 5, the mounting angle of the mounting base 42 is changed, thereby changing the sweeping angle of the sweeping brush 41 to suit different usage environments.

[0044] In some implementations, one end of the mounting bracket 1 is fixed to the vehicle frame; this is the fixed end. A vertical plate is welded to the fixed end and secured to the vehicle with bolts and nuts. The mounting bracket 1 is arranged along the vehicle's forward direction, and the sweeping brush frame 3 is located on the side, causing the sweeping brush 41 to swing outwards and closer to the roadside, ensuring effective roadside cleaning. The other end is a non-fixed end, on which an upper seat plate 12, a lower seat plate 13, and a fixing cylinder 14 located between the upper seat plate 12 and the lower seat plate 13 are installed. The fixed cylinder 14 is fixed by welding. The fixed seat 31 is also composed of an upper plate and a lower plate. The upper seat plate 12 is provided with a boss to cooperate with the upper plate. A bearing is provided between the lower plate and the lower seat plate 13 to ensure smooth rotation. The rotary cylinder 2 is installed in the fixed cylinder 14 by bolts. A limiting sleeve 22 is connected to the output end. The limiting boss 21 is welded to the side of the limiting sleeve 22. The limiting sleeve 22 extends from the lower side of the fixed seat 31. The upper seat plate 12 and the lower seat plate 13 are hinged to the fixed seat 31.

[0045] The advantage of adopting the above technical solution is that the upper base plate 12 and the lower base plate 13 are configured to connect with the fixed base 31, so that the fixed base 31 can rotate relative to each other. At the same time, the fixed cylinder 14 is configured to install the rotary cylinder 2 and also plays a protective role, ensuring that the rotary cylinder 2 is not affected by external force collisions and effectively extending its service life.

[0046] Furthermore, the side of the fixed base 31 is provided with a protruding lug 311, which is hinged to the extended end of the extension drive member 11, and the extension drive member 11 is hinged to the fixed frame 1.

[0047] The protruding lug 311 facilitates the connection of the output end of the extension drive 11. When the output end of the extension drive 11 retracts, it drives the protruding lug 311 to rotate, which in turn drives the brush holder 3 to extend outward and change the angle. Both ends of the extension drive 11 are hinged, so that it will not get stuck during the process of driving the brush holder 3 to move.

[0048] Furthermore, the rotary cylinder 2 is equipped with an encoder. The encoder is used to control the rotation angle of the rotary cylinder 2, and further control the position of the limiting boss 21, thereby limiting the extension angle of the sweeping disc, realizing the adjustment of the sweeping disc extension angle, and ultimately achieving flexible changes in the cleaning width of the side brush.

[0049] In some implementations, a spray frame 6 is mounted on the upper side of the mounting base 42, and the spray frame 6 is provided with multiple spray nozzles 61. The spray frame 6 includes two arc-shaped spray pipes 62, and multiple connecting pipes are provided between the spray pipes 62 to connect the two arc-shaped spray pipes 62. The number of spray nozzles 61 is multiple, which are evenly arranged on the outer spray pipe 62 and are provided with water inlets 63. The two ends of the arc-shaped spray pipe 62 are provided with mounting parts, and the mounting parts are provided with through holes. They are fixed to the mounting base 42 by bolts. When spraying, the water entering the spray pipe 62 is quickly and evenly distributed to the outer spray pipe 62, so that all the spray nozzles 61 spray water evenly, reducing dust and protecting the environment.

[0050] Furthermore, the brush holder 3 includes a connecting rod 33, the two ends of which are hinged to the fixed seat 31 and the mounting seat 42. The brush lifting cylinder 44 is hinged to the fixed seat 31, and its extended end is hinged to the connecting rod 33.

[0051] The advantage of adopting the above technical solution is that the connecting rod 33 is used to connect the mounting base 42 and the fixed base 31. At the same time, the hinged setting allows the angle of the connecting rod 33 to change under the drive of the brush lifting cylinder 44, so as to raise and lower the brush 41 and change the position of the brush 41.

[0052] Furthermore, the extension drive 11 is a cylinder, which is arranged along the fixed frame 1.

[0053] When the sweeper is working, the cylinder piston rod retracts, causing the sweeping brush 41 to extend outwards. If the sweeping brush 41 encounters an impact during operation, the cylinder piston rod will extend outwards, causing the sweeping brush 41 to retract. The pneumatic resistance is used to absorb the impact force, protecting the sweeping brush 41 from damage. Compared with the traditional structure that adds springs and other measures, the structure is simpler, more reliable and stable.

[0054] Furthermore, the spray frame 6 includes two arc-shaped spray pipes 62, which are connected to each other and are provided with a water inlet 63.

[0055] The advantage of adopting the above technical solution is that the two arc-shaped spray pipes 62 ensure installation strength, and the water inlet 63 is set for connecting the water inlet pipe.

[0056] In operation, the mounting bracket 1 is first installed on the cleaning vehicle. As the cleaning vehicle moves, the rotating cylinder 2 moves to change the position of the limiting boss 21. When the position of the limiting boss 21 remains unchanged, the cylinder extends and retracts, causing the brush 41 to retract or extend outward. The limiting boss 21 restricts the position of the limiting block 32, further controlling the outward extension angle of the brush 41, thus achieving stepless adjustment of the outward extension angle of the brush 41, i.e., the sweeping width of the sweeper is adjustable. In addition to driving the brush 41 to retract inward and extend outward, when the sweeper is working, the piston rod of the cylinder retracts, causing the brush 41 to extend outward. If the brush 41 encounters an impact during operation, the piston rod of the cylinder will extend outward, causing the brush 41 to retract. The pneumatic resistance is used to absorb the impact force, protecting the brush 41 from damage. Compared with the traditional structure with added springs and other measures, the structure is simpler, more reliable and stable.

[0057] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
