[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] See also Figure 1-Figure 3 As shown, the utility model provides a detachable sweeper wheel set, comprising:

[0024] The wheel assembly mounting bracket 3 is provided with a sinking hole 2. The wheel assembly mounting bracket 3 is a plate-like structure. The sinking hole 2 provided thereon is used for the subsequent installation of the driving wheel assembly 4, and can reserve space for the driving wheel assembly 4 to move up and down, thereby adjusting the position of the driving wheel assembly 4 to meet the shock absorption requirements during the movement of the equipment;

[0025] The transmission box 6 is rotatably mounted above the wheel assembly mounting bracket 3. A transmission gear is arranged inside the transmission box 6, which can cooperate with the drive motor 9 to transmit power, thereby driving the drive wheel assembly 4 to rotate. A motor mounting groove 10 is arranged on the side wall of the transmission box 6. The motor mounting groove 10 is used to cooperate with the drive motor 9 to be inserted for installation, so as to ensure that the drive motor 9 remains stable during the operation of the equipment;

[0026] The driving wheel set 4 is arranged outside the transmission box 6, rotates under the action of the transmission box 6, and contacts the ground to realize the driving of the equipment;

[0027] The driving motor 9 is plugged into the motor mounting slot 10 and fixedly connected to the internal gear of the transmission box 6 to drive the driving wheel set 4 to rotate;

[0028] The self-tapping screw 1 is arranged on the wheel assembly mounting bracket 3. The self-tapping screw 1 is used to fix the mounting bracket on the bottom surface of the sweeper body 15. When disassembling, the self-tapping screw 1 is removed to realize the overall disassembly and assembly of the wheel assembly. There are four self-tapping screws 1, which are respectively arranged at the edges of the wheel assembly mounting bracket 3. When used, bolts can be used for fixing and installation, thereby realizing the disassembly of the wheel assembly;

[0029] A mounting protrusion 8 is provided on the transmission box 6, a mounting protrusion 2 5 is provided on the wheel assembly mounting bracket 3, and a connecting spring 7 is provided between the mounting protrusion 8 and the mounting protrusion 2 5. By providing the connecting spring 7 to connect the mounting protrusion 8 and the mounting protrusion 2 5, the transmission box 6 and the driving wheel assembly 4 can be pulled downward, so that the driving wheel assembly 4 is close to the ground, thereby maintaining adhesion and preventing the wheel body from idling and affecting the passing capacity of the equipment;

[0030] During installation, the operator rotates the transmission box 6 and installs it on the wheel assembly mounting bracket 3, then uses the connecting spring 7 to connect the hanging protrusion 1 8 and the hanging protrusion 2 5, inserts the drive motor 9 into the motor groove on the transmission box 6, and connects the wiring of the drive motor 9 to the jack inside the sweeper body 15, so as to realize the electric control of the drive motor 9, and then aligns the hole position on the wheel assembly mounting bracket 3, and fixes the wheel assembly mounting bracket with the self-tapping screw 1, that is, the disassembly and assembly of the wheel assembly is completed. During the movement of the sweeper, the drive motor 9 drives the gear inside the transmission box 6 to rotate, and finally drives the drive wheel assembly 4 to rotate, so that the drive wheel assembly 4 is closely fitted to the ground, thereby ensuring the fitting effect of the sweeper during movement;

[0031] During disassembly, the four self-tapping screws 1 are removed to achieve the overall disassembly of the wheel set. At the same time, the connection between the wheel set mounting bracket 3 and the transmission box 6 can be released by removing the connecting spring 7, so that the purpose of cleaning and replacing the driving wheel set 4 can be achieved separately. The operation is simple and convenient.

[0032] In another embodiment, a pin mounting seat 13 is provided on the wheel assembly mounting bracket 3, and a pin positioning protrusion 11 corresponding to the position of the pin mounting seat 13 is provided on the transmission box 6. A latch shaft 12 is provided between the pin mounting seat 13 and the pin positioning protrusion 11. The transmission box 6 is rotatably installed on the wheel assembly mounting bracket 3 through the latch shaft 12, and the transmission box 6 and the wheel assembly mounting bracket 3 can be separated by removing the latch shaft 12, thereby reducing the difficulty of disassembly and assembly. During the operation of the equipment, the driving wheel assembly 4 can be moved on the wheel assembly mounting bracket 3.

[0033] In another embodiment, a marking area 14 is provided on the wheel assembly mounting bracket 3. The design of the marking area 14 can facilitate the installer to identify the structural positions of the left and right wheel assemblies during installation, thereby reducing the difficulty of assembly.

[0034] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
