Technical Field

[0001] The present invention relates to the technical field of logistics and transportation, and in particular to an automatic transportation robot. Background Art

[0002] Logistics and transportation technology mainly includes two categories: transportation facilities and transportation operations. The former belongs to transportation hard technology, and the latter belongs to transportation soft technology. Transportation hard technology mainly includes transportation infrastructure, such as roads, railways, shipping, transportation vehicles and other infrastructure improvements, while transportation soft technology includes management methods, logistics technology, logistics personnel quality, etc.

[0003] Most of the short-term transfer transportation devices in logistics transportation use automatic transport robots for transportation work. When transporting dusty goods, since the external packaging bags cannot completely prevent the internal dust from overflowing, the inner wall of the transport box inside the transport robot is contaminated with dust during use.

A dust leakage groove is opened in the middle of the bottom of the movable base 1.

[0035] When it is necessary to clean the inner wall of the transport box 3, the motor 601 is used to make the cleaning roller 704 clean the front and back inner walls of the transport box 3, and then the dust remaining on the inner wall of the transport box 3 is removed by the dust roller arranged on the back of the protective frame 804. As the cleaning roller 704 rotates while moving, the brush on the cleaning roller 704 can contact the dust roller, and the dust adsorbed on the dust roller can be brushed off.

[0036] When the cleaning roller 704 moves, the scraper plate 705 at the top of the cleaning roller 704 moves, and can clean the inner walls of the front end and the rear end of the top of the transport box 3 to prevent dust accumulation in the corners.

As the cleaning roller 704 rotates while moving, the brush on the cleaning roller 704 can contact the dust collecting roller, and the dust adsorbed on the dust collecting roller can be brushed off. At the same time, when the cleaning roller 704 moves, the scraper plate 705 at the top of the cleaning roller 704 moves to clean the inner walls of the front and rear ends of the top of the transport box 3 to prevent dust accumulation in the corners. At the same time, when the scraper plate 705 moves, it drives the cleaning roller 2 706 in contact with the inner wall of the top of the transport box 3 to rotate, so that the cleaning roller 2 706 can rotate to the top of the transport box 3. The inner wall of the bottom portion can be cleaned, and the inner wall of the top of the transport box 3 can be cleaned. At the same time, when the cleaning roller 704 moves, it drives the bottom movable scraper 803 to move, so that the movable scraper 803 can push the dust accumulated on the bottom inner wall of the transport box 3 and scrape off the dust on the bottom inner wall of the transport box 3. Then, by turning on the ball fan 802 in the protective box 801, the air on the right side of the protective box 801 can be sucked in, and the air can be blown into the transport box 3 through the ventilation slot, so that the dust swept on the inner wall of the transport box 3 can be blown away, so as to prevent dust from piling up on the inner wall of the transport box 3, and the cleaning effect can be better.
