The brush body assembly comprises a front rolling brush 5-1 which is rotatably connected with the front connecting beam 4-1 of the brush frame and a tail brush 5-3 which is rotatably connected with the lower part of the middle beam 4-2 of the brush frame and can extend out of the middle rolling brush 5-2 and is fixedly arranged at the rear end of the rear connecting beam 4-3 of the brush frame.

The rolling brush baffle comprises a rolling brush front baffle 6-1 and a rolling brush rear baffle 6-2 which are fixedly arranged in front of and behind a front rotating shaft seat 5-6, side baffles 6-5 which are fixedly arranged on the left side and the right side of the rolling brush front baffle 6-1 and the rolling brush rear baffle 6-2, a middle brush baffle 6-3 which is fixedly arranged below a middle brush fixing plate, and a floating baffle 6-4 which is arranged below the middle brush baffle 6-3 in a sliding mode through 2 groups of three sections of sliding rails.

The scraper is provided with a polyurethane plate which has certain elasticity, wear resistance and corrosion resistance. Comprises a front scraper 7-1 fixedly arranged below a rear baffle 6-2 of the rolling brush, a middle scraper 7-2 fixedly arranged below a middle brush baffle 6-3 and a floating scraper 7-3 below a floating baffle 6-4.

The lifting motor 3 is mounted at the bottom of the robot body in a penetrating manner, and is preferably a stepping motor. The front end of the brush holder 4 is the front end of the robot in the advancing direction. The robot is circular structure, keeps away barrier ability reinforce.

When the robot cleans, the brush frame 4 is driven by the lifting motor 3, the sliding block drives the brush frame 4 and the brushes fixedly arranged on the brush frame to move downwards, and the pressure of the brush hairs on the ground is adjusted through the control system; after the cleaning operation is finished, the brush holder 4 is controlled to lift through the control system, so that the bristles are separated from the ground and run to a designated position, such as a cleaning area or a charging position.

The rotating speed and the steering of the four omnidirectional wheels 1 are controlled by a driving assembly in the walking mechanism, so that the robot can start, stop, advance, retreat, rotate in place or walk in the side direction.

The front rolling brush 5-1 and the middle rolling brush 5-2 comprise brush hair, a fixed cylinder of the brush hair and a roller motor in the cylinder. The cleaning of a certain space outside the robot is realized through the middle rolling brush 5-2 which is arranged in a telescopic mode, and in a non-working state, the middle rolling brush 5-2 can be retracted below the robot body, so that the occupied space of the robot in the non-working state is effectively reduced. By adopting the telescopic mode of the middle rolling brush 5-2 in the application, the cleaning capacity and the working efficiency of the robot are effectively improved.

The robot brush holder 4 is connected with the rolling brush component through the nested bearing 8 and the tension spring 9, so that the rolling brush component deflects left and right; the combination of the double-slider electric sliding table 2, the floating plate 10 and the compression spring 11 realizes the up-and-down floating of the whole brush holder.

The brush hair of the tail brush 5-3 is obliquely arranged towards the rear of the advancing direction of the robot body. The brush bristles can be tightly attached to the ground, so that cleaning operation can be better completed, and the cleaning efficiency is further improved.

This application convenient to use, clearance thoroughly, energy-concerving and environment-protective, can realize the full automatization clearance mode of pig house, improved work efficiency at to a great extent, improved the environmental condition of pig house.

The working principle of the pigsty cleaning robot is as follows:

the application can realize an automatic unmanned management mode, and realizes remote Internet of things multi-machine cooperative work through APP software and robot hardware connection.
