Description

Technical Field

[0001] This utility model relates to the field of sweeper brush disc installation technology, and in particular to a sweeper brush disc support device. Background Technology

[0002] Currently, in the field of existing sweeper technology, the brush disc is the core component of sweeping operations. The stability and reliability of its installation directly affect the overall sweeping effect and operating efficiency of the sweeper. Traditional sweeper brush disc installation methods often have some obvious defects. These defects not only affect the quality of sweeping operations, but also shorten the service life of the brush disc and related components.

[0003] Traditional sweeper brushes are often installed using simple fixing methods, such as direct bolt fastening or fixing at a single support point. These installation methods often fail to provide sufficient stability and support when facing complex and ever-changing cleaning environments. During the operation of the sweeper, the brushes are easily subjected to vibration, impact, or external forces, causing them to shake or shift, resulting in incomplete cleaning, leaving blind spots, or even damaging the brushes themselves.

[0004] To address these issues, we propose a brush disc support device for sweepers, ensuring that the brush disc does not easily shake during operation and improving the stability and reliability of the sweeper's cleaning work. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a brush disc support device for sweeping vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brush disc support device for a sweeper includes: a brush disc, an outer cover fixedly connected to the top outer side of the brush disc, an mounting plate movably installed on the inner wall of the outer cover, a bushing fixedly connected to one side of the middle of the mounting plate, the bushing being fixedly installed on the bottom front end of the sweeper, three sets of equidistant mounting holes being opened on the outer side of the mounting plate, the three sets of mounting holes corresponding to three sets of positioning support mechanisms installed on the brush disc, a pressing component being installed between two adjacent sets of positioning support mechanisms, and all three sets of pressing components being installed on the mounting plate.

[0008] Preferably, the positioning support mechanism includes a mounting shaft fixedly connected to the top of the brush disc, a locking block fixedly connected to the other end of the mounting shaft, a stop ring slidably installed on one side of the mounting shaft, and a first spring fixedly installed at the bottom of the stop ring. The first spring is sleeved on the outer wall of the mounting shaft. Each set of the first springs is fixedly installed on both sides of the brush disc and the side wall of the stop ring, respectively. The three sets of mounting shafts correspond to the three sets of mounting holes, ensuring that the brush disc is not easily shaken during operation.

[0009] Preferably, the outer diameter of the abutment ring is greater than the inner diameter of the mounting hole, the outer diameter of the mounting shaft is less than the outer diameter of the locking block, and the outer diameter of the locking block is less than the inner diameter of the mounting hole, so that the mounting plate can be supported on the mounting circumference.

[0010] Preferably, each of the three sets of mounting holes has a lock hole connected on one side. The inner diameter of the lock hole is smaller than the inner diameter of the mounting hole. The mounting shaft fits into the lock hole. The outer diameter of the lock block is larger than the inner diameter of the mounting hole, so that the mounting shaft can be positioned inside the mounting hole.

[0011] Preferably, a motor is distributed on one side of the bushing, the motor is fixedly mounted on the sweeper, the motor drive output end is connected to the drive shaft, and a locking plate is detachably bolted to the other end of the drive shaft. The drive shaft passes through the inside of the bushing, and the locking plate is distributed on the side wall of the mounting plate, which can drive the mounting plate to rotate.

[0012] Preferably, the mounting plate has three sets of equally spaced piston holes, each set of piston holes has a slidably mounted a stop post, each set of stop posts has a baffle fixedly connected to both sides, and each set of stop posts has a second spring sleeved on the outside. The two sides of each set of second springs are fixedly mounted to the mounting plate and the side wall of the baffle, respectively, so as to support the brush plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features three sets of equidistant mounting holes on the outer side of the mounting plate that correspond to three sets of positioning support mechanisms on the brush plate. Furthermore, an extrusion assembly is installed between adjacent positioning support mechanisms. This allows the brush plate to achieve precise positioning and stable support on the mounting plate, ensuring that the brush plate does not easily shake during operation. This improves the stability and reliability of the sweeper's cleaning operation and extends the service life of the brush plate and related components.

[0015] Each of the three sets of abutments has a second spring fitted onto its outer side. Each set of second springs is fixedly installed on both sides of the mounting plate and the side wall of the baffle. When the brush plate is installed on the mounting plate, the brush plate will first squeeze the abutment in the piston hole and compress the spring fitted on the outer side of the abutment. After the brush plate is installed on the mounting plate, the baffle on one side of the three sets of abutments will fit against the side wall of the mounting plate. This not only supports the mounting plate and checks whether the brush plate is firmly installed on the mounting plate, but also, in combination with the supporting force of the spring and the friction between the baffle and the side wall of the brush plate, further improves the firmness and stability between the brush plate and the mounting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A brush disc support device for a sweeper includes: a brush disc 1, an outer cover 11 fixedly connected to the top outer side of the brush disc 1, an mounting plate 12 movably installed on the inner wall of the outer cover 11, a bushing 13 fixedly connected to one side of the middle of the mounting plate 12, the bushing 13 being fixedly installed on the bottom front end of the sweeper, three sets of equidistant mounting holes 24 opened on the outer side of the mounting plate 12, the three sets of mounting holes 24 corresponding to three sets of positioning support mechanisms installed on the brush disc 1, and a pressing component installed between adjacent sets of positioning support mechanisms. All three sets of pressing components are installed on the mounting plate 12. By using the three sets of equidistant mounting holes 24 opened on the outer side of the mounting plate 12 to correspond to the three sets of positioning support mechanisms on the brush disc 1, and by installing pressing components between adjacent positioning support mechanisms, the brush disc 1 can achieve precise positioning and stable support on the mounting plate 12, ensuring that the brush disc 1 is not easily shaken during operation, improving the stability and reliability of the sweeper's cleaning operation, and extending the service life of the brush disc 1 and related components.

[0023] Furthermore, the mounting plate 12 has three sets of equidistantly distributed piston holes 3, each with a sliding abutment 31. Each set of abutments 31 has a baffle 32 fixedly connected to both sides, and a second spring 33 is sleeved on the outer side of each set of abutments 31. Each set of second springs 33 is fixedly installed on both sides of the mounting plate 12 and the side wall of the baffle 32, providing support for the brush plate 1. When the brush plate 1 is installed on the mounting plate 12, it will preferentially press against the abutments 31 in the piston holes 3, compressing the springs sleeved on the outer side of the abutments 31. After the brush plate 1 is installed on the mounting plate 12, the baffle 32 on one side of each of the three sets of abutments 31 will adhere to the side wall of the mounting plate 12. This not only supports the mounting plate 12 and checks whether the brush plate 1 is firmly installed on the mounting plate 12, but also, in conjunction with the supporting force of the springs and the friction between the baffle 32 and the side wall of the brush plate 1, further improves the firmness and stability between the brush plate 1 and the mounting plate 12.

[0024] Furthermore, the positioning support mechanism includes a mounting shaft 2 fixedly connected to the top of the brush disc 1, a locking block 21 fixedly connected to the other end of the mounting shaft 2, a stop ring 22 slidably mounted on one side of the mounting shaft 2, and a first spring 23 fixedly mounted at the bottom of the stop ring 22. The first spring 23 is sleeved on the outer wall of the mounting shaft 2. Each set of first springs 23 is fixedly mounted on both sides of the brush disc 1 and the side wall of the stop ring 22, respectively. The three sets of mounting shafts 2 correspond to the three sets of mounting holes 24, ensuring that the brush disc 1 is not easily shaken during operation. The locking block 21 at the other end of the mounting shaft 2 is used to secure the brush disc 1. Once in place, it acts as a limit to prevent the brush disc 1 from falling off the mounting plate 12; the abutment ring 22, which is slidably installed on one side of the mounting shaft 2, and the first spring 23, which is sleeved on the outer wall of the mounting shaft 2 at the bottom of the abutment ring 22, can absorb and buffer part of the impact force when the brush disc 1 is subjected to vibration or external impact, reducing the direct effect on the brush disc 1 and further enhancing the stability of the brush disc 1. At the same time, the cooperation between the abutment ring 22 and the first spring 23 can also make the brush disc 1 maintain a certain pre-tight force after installation, ensuring that the brush disc 1 and the mounting plate 12 fit tightly together and improve the cleaning effect.

[0025] Furthermore, the outer diameter of the abutment ring 22 is larger than the inner diameter of the mounting hole 24, the outer diameter of the mounting shaft 2 is smaller than the outer diameter of the locking block 21, and the outer diameter of the locking block 21 is smaller than the inner diameter of the mounting hole 24. This allows the mounting plate 12 to be supported on the mounting circumference. Each of the three sets of mounting holes 24 has a connecting locking hole 25 on one side. The inner diameter of the locking hole 25 is smaller than the inner diameter of the mounting hole 24, allowing the mounting shaft 2 to fit into the locking hole 25. The outer diameter of the locking block 21 is larger than the inner diameter of the mounting hole 24, allowing the mounting shaft 2 to be positioned within the mounting hole 24. During the installation of the brush plate 1, the abutment ring 22 can contact the surface of the mounting plate 12, and, in conjunction with the first spring 23, can provide elastic support for the brush plate 1. Also, the outer diameter of the mounting shaft 2 is smaller than that of the locking block 21. The outer diameter of the locking block 21 is smaller than the inner diameter of the mounting hole 24, ensuring that the mounting shaft 2 can pass smoothly through the mounting hole 24. It also allows the locking block 21 to be locked on the other side of the mounting plate 12 after the brush plate 1 is installed. Together with the abutment ring 22, it can stably fix the brush plate 1 on the mounting plate 12. The structure is simple and the fixing effect is reliable. The mounting shaft 2 first passes through the mounting hole 24, and then the mounting shaft 2 enters the locking hole 25 by rotating the brush plate 1. At this time, the locking block 21 is blocked by the mounting plate 12 and cannot move in the opposite direction, thereby locking the brush plate 1 and preventing the brush plate 1 from rotating or loosening on its own due to vibration during the operation of the sweeper. This improves the firmness and safety of the installation of the brush plate 1.

[0026] Furthermore, a motor 14 is distributed on one side of the bushing 13. The motor 14 is fixedly mounted on the sweeper. The drive output end of the motor 14 is connected to the drive shaft. A locking plate 15 is detachably bolted to the other end of the drive shaft. The drive shaft passes through the inside of the bushing 13. The locking plate 15 is distributed on the side wall of the mounting plate 12 and can drive the mounting plate 12 to rotate. The drive shaft and the locking plate 15 are detachably bolted, which facilitates quick disassembly and installation when the brush plate 1 or related parts need to be repaired or replaced. This improves the maintenance efficiency and convenience of the equipment and reduces maintenance costs.

[0027] In use, align the mounting shaft 2 on the brush plate 1 with the mounting hole 24 on the mounting plate 12. Since the outer diameter of the mounting shaft 2 is smaller than the outer diameter of the locking block 21, and the outer diameter of the locking block 21 is smaller than the inner diameter of the mounting hole 24, the mounting shaft 2 can pass smoothly through the mounting hole 24. The outer diameter of the abutment ring 22 is larger than the inner diameter of the mounting hole 24, so the abutment ring 22 cannot enter the mounting hole 24 and contacts the surface of the mounting plate 12. At the same time, the first spring 23 is compressed, producing elastic deformation, which provides elastic support for the brush plate 1. Then rotate the brush plate 1 so that the mounting shaft 2 enters the locking hole 25. Since the mounting shaft 2 and the locking hole 25 fit each other, and the outer diameter of the locking block 21 is larger than the inner diameter of the mounting hole 24, the locking block 21 is blocked by the mounting plate 12 and cannot move in the opposite direction. Thus, the mounting shaft 2 is positioned in the mounting hole 24, and the brush plate 1 is initially fixed on the mounting plate 12 to prevent the brush plate 1 from rotating or loosening due to vibration during the operation of the sweeper.

[0028] When the brush plate 1 is installed on the mounting plate 12, the brush plate 1 will first squeeze the abutment 31 in the piston hole 3, causing the abutment 31 to slide in the piston hole 3. At the same time, it will compress the second spring 33 sleeved on the outside of the abutment 31. After the brush plate 1 is installed in place, the baffles 32 on one side of the three sets of abutments 31 will adhere to the side wall of the brush plate 1. The supporting force of the second spring 33 and the friction between the baffles 32 and the side wall of the brush plate 1 work together to further improve the firmness and stability between the brush plate 1 and the mounting plate 12. At the same time, by observing the adhesion between the baffles 32 and the side wall of the brush plate 1, it is also possible to detect whether the brush plate 1 is firmly installed on the mounting plate 12.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
