The coordination of the gears and chains between the transmission devices achieves reasonable matching of the rotation speed and energy transmission, reducing the setting requirements for the number of drive units.

[0022] The cutting part includes a transmission shaft 102 coaxially arranged with the protective cover 101, and the transmission shaft 102 is rotatably matched with the protective cover 101. A star arm bracket fixing sleeve 108 is fixedly sleeved on the outer surface of the transmission shaft 102, and three star arm brackets 104 are fixedly installed on the star arm bracket fixing sleeve 108 at equal intervals along its own radial direction.

All scraper wheels 105 arranged in coaxial positions are fixedly sleeved on the scraper wheel support shaft 106. One end of the star arm bracket fixing sleeve 108 is rotatably sleeved with a fixed gear 103, and the fixed gear 103 is fixedly matched with the inner wall of the protective cover 101. Three rotating synchronous gears 107 are also rotatably mounted on the side of one of the star arm brackets 104. Each rotating synchronous gear 107 is matched with the corresponding earth-cutter wheel support shaft 106 through a first chain 109, wherein the rotating synchronous gear 107 is meshed and matched with the fixed gear 103. A second gearbox 118 is fixedly mounted on the upper surface of the protective cover 101. The input shaft of the second gearbox 118, the input shaft of the first gearbox 112 and the end of the transmission shaft 102 are all rotatably mounted on the stabilizing shaft bracket 120. The stabilizing shaft bracket 120 is fixedly mounted on the protective cover 101 and the shielding ring cover bracket 132, wherein the shielding ring cover bracket 132 is used to fix the shielding ring cover 114 on the adsorption chamber 110. The input shaft of the second gearbox 118 is connected to the transmission shaft 102 through a third chain 119, and the transmission shaft 102 is connected to the input shaft of the first gearbox 112 through a second chain 117. The input shaft of the second gearbox 118 or the input shaft of the first gearbox 112 is fixedly matched with the output shaft of the drive unit, wherein the drive unit is an electric motor or an internal combustion engine. A grass-cutting shaft bracket 122 is also fixedly mounted on the outer surface of the protective cover 101, and a grass-cutting shaft 123 is rotatably mounted on the grass-cutting shaft bracket 122. The top of the grass-cutting shaft 123 is fixedly matched with the output shaft of the second gearbox 118 through a fourth chain 121, and two grass-cutting ropes 124 are fixedly mounted on the bottom of the grass-cutting shaft 123 for cutting grass stems. The protective cover 101 is fixedly mounted on the protective cover bracket 125, and the two ends of the protective cover bracket 125 are slidably mounted on two parallel guide sliding rods 126. A limiting ring 127 is fixedly mounted on the bottom end of each guide sliding rod 126, and the limiting ring 127 is used to prevent the protective cover bracket 125 from separating from the guide sliding rod 126.

[0023] It also includes two drive motor wheel support plates 128 symmetrically arranged on both sides of the protective cover 101, wherein the guide sliding rod 126 is fixedly matched with the drive motor wheel support plate 128, the protective cover bracket 125 is slidably matched with the drive motor wheel support plate 128, and the tops of the two drive motor wheel support plates 128 are fixedly matched through a support plate connecting beam 131. The two drive motor wheel support plates 128 are rotatably provided with drive motor wheels 129, and a grass collecting cover 130 is fixedly installed between the two drive motor wheel support plates 128 or on the outer surface of the protective cover 101, and the grass collecting cover 130 is arranged on the outer side of the grass cutting rope 124.

[0024] The working principle of a modern intelligent weeding robot disclosed in the present invention is as follows: four drive motor wheels 129 can be controlled independently to drive the whole to walk on the ground, and forward, rotation and reverse movement can be achieved through the cooperation of the four drive motor wheels 129. The input shaft of the second gearbox 118 is driven to rotate by the drive unit, and the output shaft of the second gearbox 118 drives the grass-cutting shaft 123 to rotate through the fourth chain 121, and the grass-cutting shaft 123 drives the grass-cutting rope 124 to rotate. When the grass-cutting rope 124 in the rotating state contacts the grass stems, the weeds will be cut off. When the input shaft of the second gearbox 118 rotates, it will drive the transmission shaft 102 to rotate through the third chain 119. At this time, the whole device moves forward, so that the protective cover 101 moves to the top of the grass-cutting rope 124 that cuts the weeds (that is, the position where the grass roots are left), and the rotation of the transmission shaft 102 will drive the planetary arm bracket fixing sleeve 108 to rotate, and the rotation of the planetary arm bracket fixing sleeve 108 will drive the planetary arm bracket fixing sleeve 108 to rotate. The star arm bracket 104 rotates, and the star arm bracket 104 rotates to drive all the scraper wheels 105 to rotate with the star arm bracket 104. At the same time, the star arm bracket 104 will also drive the rotating synchronous gear 107 to revolve. Since the fixed gear 103 is fixed to the transmission shaft 102, the rotating synchronous gear 107 will rotate around the fixed gear 103 at this time, and under the restriction of the fixed gear 103, the rotating synchronous gear 107 will also rotate on its own. The rotating synchronous gear 107 drives the scraper wheel support shaft 106 to rotate through the first chain 109, and the scraper wheel support shaft 106 drives the scraper wheel 105 at the corresponding position to rotate, and the scraper wheel 105 will move relative to the ground, dig up and destroy the soil and grass roots on the ground.The soil and grass roots dug up in this process will be dispersed in the protective cover 101 (flying around, the purpose of the protective cover 101 is to block these objects from flying around), and then will be sucked out to the designated position. This is because when the transmission shaft 102 rotates, it will drive the input shaft of the first gearbox 112 to rotate through the second chain 117 (depending on whether the output shaft of the drive unit is connected to the input shaft of the first gearbox 112 or the second gearbox 118), and the output shaft of the first gearbox 112 will drive the adsorption impeller 111 to rotate. The rotation of the adsorption impeller 111 will inhale the gas inside the protective cover 101, including the soil and grass roots dispersed in the air. The rotation of the adsorption impeller 111 will throw the inhaled gas into the exhaust channel 113, and then enter the tangent direction of the inner wall of the shielding ring cover 114 through the exhaust channel 113. The air will move toward the inner wall of the shielding ring 114, and the air will approach the axis of the shielding ring 114 due to its light weight. The grass roots and soil will rotate along the inner wall of the shielding ring 114 (under centrifugal force) due to their heavy weight. With the shielding of the two shielding ring pieces 115, only when the soil and grass roots move to the bottom of the shielding ring 114 will they slide down along the upper surface of the raised slope 116 to the outside of the shielding ring 114 (the bottom of the two shielding ring pieces 115 are provided with openings for allowing the soil and grass roots to slide out, and at the same time cooperate with the raised slope 116). The soil and grass roots that slide down will fall to the rear of the device, so that the protective cover 101 can prevent the soil and grass roots from accumulating inside the protective cover 101 while shielding the splashing objects. Under the action of its own gravity, the protective cover 101 as a whole will contact the ground, and the protective cover bracket 125 and the guide sliding rod 126 will slide relatively following the unevenness of the ground, while the grass-cutting rope 124 will maintain a certain distance from the ground.
