Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a sweeper disc brush which is easy to load and unload. Background Art

[0002] The installation steps of the disc brush on the existing sweeping machine are generally to first raise the disc brush base, then place the disc brush under the disc brush base, align the brush disc buckle above it with the flange mouth under the disc brush base, then lift the disc brush upwards, make the brush disc buckle engage with the flange buckle, and then rotate the disc brush to complete the installation of the disc brush. This installation method requires the staff to accurately align the flange mouth on the disc brush base. If it is not aligned, they can only grope for the position of the flange buckle and make the next attempt. Because the disc brush base is located at the bottom of the sweeping machine, the staff cannot clearly see the position of the flange mouth, thereby wasting a lot of installation time. In view of this, we propose a sweeping machine disc brush that is easy to load and unload. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 5 A disc brush for a sweeping machine that is easy to load and unload comprises a disc body 1 and bristles 4 arranged under the disc body 1. A disc brush base 2 connected to the sweeping machine is provided on the upper part of the disc body 1, and a mounting assembly 5 connected to the sweeping machine is provided on the upper part of the disc brush base 2. A connecting mechanism 3 connected to the disc brush base 2 is provided on the disc body 1. When installing for the first time, the disc brush base 2 can be installed on the sweeping machine through the mounting assembly 5, and then the connecting mechanism 3 is operated to connect the disc body 1 and the disc brush base 2 together, thereby completing the assembly of the disc brush.

[0023] The connecting mechanism 3 includes a connecting sleeve 31 slidably mounted on the disc body 1, and a connecting rod 32 is elastically hinged on the outside of the connecting sleeve 31. A clamping hole 34 for the connecting rod 32 to slide is opened on the disc brush base 2. A clamping rod 35 is elastically mounted in the inner cavity of the clamping hole 34. The outside of the clamping rod 35 is in contact with the outside of the connecting rod 32. Since the connecting sleeve 31 is slidably connected to the disc body 1, when installing the disc body 1, the connecting sleeve 31 can be first retracted into the disc body 1. During the retraction process, the connecting rod 32 will rotate and retract to the surface of the connecting sleeve 31, and the disc brush base 2 will be installed. When the body 1 is aligned with the disc brush base 2, the connecting sleeve 31 is inserted into the engaging hole 34 in the disc brush base 2. At this time, the connecting rod 32 without restraint begins to rotate and reset under the action of its own elastic force. During the rotation, the engaging rod 35 is squeezed downward to shrink, thereby forming an engaging groove in the engaging hole 34 that engages with the connecting rod 32. This solves the problem of having to align the engaging hole on the flange when installing the traditional disc brush, thereby reducing the installation difficulty between the disc brush and the sweeper, reducing the installation time of the disc brush, and improving the installation efficiency of the disc brush.

[0024] A driving connecting rod 33 fixedly connected to the connecting sleeve 31 is elastically installed inside the disk body 1. The cross-section of the driving connecting rod 33 is C-shaped, and both ends of the driving connecting rod 33 slide through the disk body 1. Since both ends of the driving connecting rod 33 slide through the disk body 1 and are exposed to the outside of the disk body 1, and the upper part of the driving connecting rod 33 is fixedly connected to the connecting sleeve 31, when installing the disk body 1, the connecting sleeve 31 can be driven to shrink into the disk body 1 by pulling the two ends of the driving connecting rod 33.

[0025] Embodiment 2

[0026] Reference Figure 1-Figure 5 , this embodiment is basically the same as the first embodiment, and is more optimized in that the mounting assembly 5 includes a driving gear 51 and a driven gear 52 rotatably mounted on the disc brush base 2, the driven gear 52 is provided with a mounting threaded barrel 54 threadedly connected to the sweeper bolt, and the upper end of the mounting threaded barrel 54 passes through the disc brush base 2, the driving gear 51 and the driven gear 52 are externally meshed with a synchronous gear ring 53 rotatably connected to the disc brush base 2, the upper part of the driving gear 51 is coaxially fixed with a rotating shaft that passes through the disc brush base 2, and a rotating end block 55 is fixedly installed through the rotating shaft, when the disc brush base 2 is connected to the sweeper, the mounting threaded barrel 54 can be rotated to make it threadedly connected to the mounting bolt on the sweeper, thereby achieving the installation of the disc. The function of the brush base 2, in this solution, a driving gear 51, a driven gear 52 and a synchronous gear ring 53 are provided in the disc brush base 2. During installation, the driving gear 51 can be driven to rotate by rotating the rotating end block 55. After the driving gear 51 rotates, it will drive the synchronous gear ring 53, which is rotatably connected to the disc brush base 2, to rotate through the meshing of teeth, thereby achieving the effect of engaging the driven gear 52 to rotate. Because the driven gear 52 is fixedly sleeved on the outside of the installation threaded cylinder 54, when the driven gear 52 rotates, it will drive the installation threaded cylinder 54 to be connected with the installation bolts, thereby achieving the effect of synchronously mobilizing the rotation of each installation threaded cylinder 54, thereby improving the convenience of connection between the disc brush base 2 and the sweeper and increasing the installation efficiency.

[0027] A limiting sleeve 56 is provided on the external sliding sleeve of the rotating end block 55, and a limiting spring 57 with one end fixedly connected to the disc brush base 2 is fixedly installed at the lower part of the limiting sleeve 56. Under normal conditions, the rotation of the rotating end block 55 can be limited by the engagement of the limiting sleeve 56 with the rotating end block 55, thereby ensuring the stability of the connection between the disc brush base 2 and the sweeper. During loading and unloading, under the squeezing of the wrench, the limiting sleeve 56 will automatically detach from the rotating end block 55, releasing the limit on it, thereby facilitating the loading and unloading of the disc brush base 2.

[0028] A fixed block is fixedly installed on the upper part of the bristles 4, and an adjusting assembly 6 for adjusting the horizontal height of the fixed block is arranged inside the disc body 1. The adjusting assembly 6 includes an adjusting gear 61 rotatably installed inside the disc body 1, and an adjusting rack 62 fixedly connected to the fixed block is meshed on the outside of the adjusting gear 61. A cross groove is opened inside the adjusting gear 61, and a cross protrusion 63 is slidably installed through the cross groove. An adjusting screw rod 64 is arranged at one end of the cross protrusion 63, and the adjusting screw rod 64 is threadedly connected to the disc body 1. One end of the adjusting screw rod 64 passes through the disc body 1 and is installed with a turntable. During the working process of the sweeper, the bristles 4 will often contact with the ground, and will wear out over time, affecting the cleaning effect. Sweeping effect, the conventional solution is to directly replace the disc brush. The adjusting component 6 in the present device can control the height of the bristles 4 from the ground through the fixed block, thereby extending the service life of the bristles 4 and reducing the use cost of the product of the sweeper. The specific steps are as follows. The staff can drive the adjusting screw 64 to rotate by rotating the turntable. When the adjusting screw 64 rotates, it will drive the adjusting gear 61 to rotate through the engagement between the cross protrusion 63 and the cross groove. The adjusting gear 61 drives the adjusting rack 62 to descend through the meshing of teeth. Since one end of the adjusting rack 62 is fixedly connected to the fixed block, the height of the fixed block can be adjusted synchronously, thereby achieving the effect of controlling the height of the bristles 4 from the ground.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
