[0021] In order to make the above objectives, characteristics and advantages of the utility model more apparent, obvious and comprehensible, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] Please refer to Figs. 1 to 3 The utility model discloses a rotary tillage weeding film uncovering machine, including rotary tillage unit and uncovering film unit.

[0023] The rotary tillage unit includes a rotary tillage frame 11, a power mechanism 12 mounted on the rotary tillage frame 11, a first transmission mechanism 13 connected with the power mechanism 12, and a rotary tillage cutter 14 connected with the first transmission mechanism 13. The power mechanism 12 can be a gasoline engine. The uncovering film unit includes an uncovering film frame 21 mounted on the top of the rotary tillage frame 11, an uncovering film shaft 22 rotatably mounted on the uncovering film frame 21, uncovering film cylinders 23 mounted on both ends of the uncovering film shaft 22, and a second transmission mechanism 24 mounted between the first transmission mechanism 13 and the uncovering film shaft 22. The second transmission mechanism 24 is used to transmit power from the first transmission mechanism 13 to the uncovering film shaft 22. A speed regulating mechanism is mounted on the second transmission mechanism 24 to adjust the rotational speed of the uncovering film shaft 22.

[0024] The rotary tillage cutter 14 serves as a replacement for the walking wheels. During walking, the rotary tillage cutter 14 can simultaneously perform rotary tillage and soil loosening in the furrow, thereby achieving weeding. In addition, the speed regulating mechanism can adjust the rotational speed of the uncovering film shaft 22 as needed, thereby adjusting the rotational speed of the uncovering film frame 21. This can prevent the rotary tillage cutter 14 from slipping while the uncovering film cylinder 23 rotates normally, thereby preventing the mulch film from being pulled and affecting normal rolling.

[0025] The first transmission mechanism 13 includes a worm and gear mechanism 131 and a rotating shaft 132. The worm and gear mechanism 131 includes a worm and a gear that mesh with each other. The worm is connected with the output shaft of the power mechanism 12, and the rotating shaft 132 is connected with the gear. The two ends of the rotating shaft 132 extend to the two sides of the rotary tillage frame 11, and the rotary tillage cutter 14 is mounted on the rotating shaft 132 on both sides. The rotary tillage cutter 14 is a conventional cutter. During operation, the gasoline engine drives the worm, the gear, and the rotating shaft 132 to rotate, thereby driving the rotary tillage cutter 14 to rotate. Since the worm and gear mechanism 131 is a common knowledge in the art, it will not be described in detail.

[0026] In order to facilitate the speed regulation, the second transmission mechanism 24 comprises a driving sprocket 241, a driven sprocket 242 and a transmission chain 243, the driving sprocket 241 is installed on the rotating shaft 132, and the driving sprocket 241 is a multi-stage sprocket, the driven sprocket 242 is installed on the film uncovering shaft 22, the transmission chain 243 connects the driving sprocket 241 and the driven sprocket 242, the speed regulation mechanism comprises a chain derailleur 244 and a controller 245, the chain derailleur 244 is installed on the film uncovering frame 21, and the transmission chain 243 passes through the chain derailleur 244, the controller 245 is installed on the armrest of the rotary tiller frame 11, the controller 245 is used for controlling the action of the chain derailleur 244, the controller 245 can be a manually operated lever or knob, and the transmission chain 243 is controlled to change the position on the multi-stage sprocket, so that the rotating speed of the film uncovering shaft 22 relative to the rotating shaft 132 is changed, for example, when the rotary tiller cutter 14 slips, the rotating speed of the film uncovering shaft 22 is controlled to slow down, and when the rotary tiller cutter 14 normally moves forward, the film uncovering shaft 22 is ensured to have the same rotating speed as the rotating shaft 132.

[0027] In order to avoid the splashed mud from affecting the normal work of the transmission chain 243, a mud cover 15 is installed on the lower part of the side of the rotary tiller frame 11 and located outside the driving sprocket 241 and the transmission chain 243.

[0028] In order to facilitate the operation, a limiting frame 16 is arranged at the bottom of the rear end of the rotary tiller frame 11, the bottom of the limiting frame 16 is provided with a rotatable limiting wheel 17, the limiting wheel 17 is located behind the rotary tiller cutter 14, and the height of the limiting wheel 17 is arranged between the top and the bottom of the rotary tiller cutter 14, so that the operability is improved, and the rotary tiller cutter 14 is prevented from slipping and idling to a certain extent.

[0029] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent range. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the utility model, a plurality of modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
