Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a building cleaning robot. Background Art

[0002] After construction is completed, a large amount of construction waste is left on the ground, which needs to be cleaned up quickly, especially on the concrete floor. This waste is disorganized and the manual cleaning process is complex, increasing labor intensity and affecting construction efficiency. Therefore, the existing technology proposes to use automated cleaning equipment to replace manual cleaning of construction waste.

[0003] For example, the utility model with announcement number CN221029841U discloses a construction site cleaning device. Its principle is to use a cleaning brush to sweep construction waste and dust, and then use an exhaust fan to provide suction to transfer the waste and dust to a collection box through an air duct. However, using an exhaust fan to transfer waste is only suitable for light and small particulate waste. After construction, not only light and small particulate waste is left on the ground, but also waste with irregular size and relatively large weight, such as scrap steel bars, scrap iron wire, and scrap electrical wire. This waste is difficult to be sucked up by the exhaust fan and cannot be transferred to the collection box through the pipe. Therefore, new requirements are put forward for construction cleaning equipment. Utility Model Content

[0004] Based on this, it is necessary to provide a building cleaning robot, and its specific technical solution is as follows.

[0005] A building cleaning robot, comprising:

[0006] A mobile cart is equipped with a collection box, wherein the collection box includes an opening;

[0032] Example

[0033] Reference Figure 1 and Figure 2 As shown, this embodiment provides a construction cleaning robot comprising a mobile vehicle 1, a bucket 2, and a conveying assembly 3. The mobile vehicle 1 comprises a base 12, a housing 11, and a travel system 13. The housing 11 is mounted on the base 12 and surrounds the conveying assembly 3. The travel system 13 is connected to the base 12 and drives the base 12 to move. The travel system 13 is conventional in the art and will not be described in detail in this embodiment. A collection box 14 is mounted on the top of the chassis. The collection box 14 has an opening, which is a top opening for collecting construction waste.

[0034] The bucket 2 is mounted on the end of the mobile cart 1. The bottom of the bucket 2 is in contact with the ground or forms a gap of 0.1 to 0.5 cm with the ground. The bucket 2 has an open collecting end 21 that faces the direction of travel of the mobile cart 1. When the mobile cart 1 is driven forward, construction waste on the path enters the bucket 2 through the collecting end 21, and the construction waste is collected from the ground.

[0035] Reference Figure 2 As shown, the conveying assembly 3 includes a conveyor belt 31, a driving device and a scraper 33; the driving device includes two rotating rollers 32 and a driving motor, wherein one rotating roller 32 is close to the opening of the collection box 14, and the other rotating roller 32 is close to the bucket 2. The driving motor rotates the rollers 32, and the conveyor belt 31 passes over the two rotating rollers 32 so that the conveyor belt 31 is close to the opening of the bucket 2 and the collection box 14 respectively. The conveyor belt 31 is driven by the driving device to move between the bucket 2 and the collection box 14. The surface of the conveyor belt 31 is provided with an array of collecting teeth 34, refer to Figure 3As shown, the collecting teeth 34 include a hard rod portion 341 and a soft rubber portion 342. The rod portion 341 is mounted on the surface of the conveyor belt 31 and protrudes outward from the conveyor belt 31. The rubber portion 342 includes a first section 343 that wraps around the rod portion 341 and a second section 344 that extends outward along the rod's axis. The scraper 33 is mounted at the top opening of the collection box 14 and abuts against the conveyor belt 31. The scraper 33 is provided with a slot 331 that accommodates the rod portion. The length of the slot 331 is shorter than the length of the rubber portion 342, so that the second end of the rubber portion 342 is bent when passing through the slot 331. When construction waste is collected in the bucket 2, it moves toward the conveyor belt 31 due to inertia. When the waste contacts the collecting teeth 34, irregularly shaped waste is attracted by the collecting teeth 34 and moves with the collecting teeth 34. In this embodiment, bucket 2 has a certain inclination. Due to inertia and the thrust of other garbage, bucket 2 guides the garbage onto conveyor belt 31. When the garbage contacts scraper 33, second section 344 of rubber portion 342 is bent by scraper 33, allowing the garbage to pass through. The garbage cannot pass through scraper 33 and is separated from conveyor belt 31. Guided by scraper 33, the garbage enters collection box 14, where it is collected.

[0036] This embodiment provides a building cleaning robot. The collecting teeth 34 on the surface of the conveyor belt 31 can better adhere irregularly shaped garbage to the conveyor belt 31. As the conveyor belt 31 moves, it can transport heavier and bulkier garbage than an exhaust fan. The scraper 33 squeezes the rubber portion 342, which bends, causing the scraper 33 to contact the garbage, separating it from the conveyor belt 31 and thus collecting the garbage. This utility model can collect irregularly shaped and bulky garbage, providing enhanced cleaning capabilities and a wider range of applications.

[0037] Specifically, the conveyor belt 31 includes a first end and a second end. The first end is located near the collection box 14, and the second end is located near the bucket 2. The conveyor belt 31 is arranged at an angle from the first end to the second end, with the first end being higher than the second end. Trash adheres to the surface of the conveyor belt 31 and moves toward the collection box 14 as the conveyor belt 31 moves.

[0038] Specifically, the scraper 33 includes a third end and a fourth end. The third end abuts the conveyor belt 31, and the fourth end extends into the opening of the collection box 14. The scraper 33 is arranged at an angle from the third end to the fourth end, with the third end being higher than the fourth end. Guided by the scraper 33 and under the action of gravity, the garbage enters the collection box 14.

[0039] Specifically, the robot also includes two sets of cleaning brushes 4, which are mounted on the housing 11 via a first drive motor and driven to rotate by the motor. The cleaning brushes 4 are located at the front end of the bucket 2 and are used to drive garbage toward the bucket 2 during rotation. The two sets of cleaning brushes 4 rotate in opposite directions, and as they rotate, they guide garbage toward the center of the two sets of cleaning brushes 4. As the cleaning brushes 4 rotate, they contact the ground, driving garbage toward the center of the brushes 4. During the robot's movement, garbage is forced into the bucket 2 and exerted a certain force on the garbage, causing it to move relative to the bucket 2 toward the conveyor belt 31.

[0040] Working principle: Drive the robot to move, so that the cleaning brush 4 rotates to collect the garbage to the middle position, and the garbage enters the bucket 2. The garbage adheres to the collecting teeth 34 and moves with the conveyor belt 31 to the scraper 33. The scraper 33 separates the garbage and the conveyor belt 31 and the garbage enters the collection box 14 to be collected.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
