The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See also Figure 1 to Figure 2 , shown is a corn stubble soil removal and recovery device in the first embodiment of the utility model, including a traction frame 1, one side of the traction frame 1 is connected to a frame 11 through a hinge, the upper end of the frame 11 is provided with a power drive assembly 10, the lower end of the frame 11 is provided with a conveying device 9, one end of the conveying device 9 is provided with a ground support screen 7 matched with the conveying device 9, the ground support screen 7 is located on the lower side of the traction frame 1, the conveying device 9 is fixedly arranged on the drum bracket 2 away from the ground support screen 7, the drum bracket 2 is rotatably provided with a drum assembly 3, the drum assembly 3 includes a drum body 34, and the inner side wall of the drum body 34 is fixedly provided with a drum brush 36, the roller brush 36 is spiral-shaped, and a plurality of cone spikes 35 are fixedly arranged on one side of the roller body 34, each of the cone spikes 35 is arranged in a circular array on the inner wall of the roller body 34 along the central axis of the roller body 34, and mounting rings 37 are provided at both ends of the roller body 34. A gear ring 33 is provided on the side of the roller body 34 close to the conveying device 9, and the gear ring 33 is fixedly connected to one side of the mounting ring 37, and a plowshare assembly 6 is provided on the side of the ground support screen 7 away from the conveying device 9, and the plowshare assembly 6, the conveying device 9 and the roller assembly 3 are connected through a transmission assembly and are indirectly connected to the power drive assembly 10.

[0037] It should be noted that the plowshare assembly 6, the ground-supporting screen 7 and the conveying device 9 are arranged in sequence from front to back and installed on the frame. In order to ensure that the stubble dug up by the plowshare assembly 6 can be collected, the front end of the ground-supporting screen 7 is close to and flush with the ground, and the rear end is flush with the front end of the conveying device 9. At the same time, in order to remove loose soil, the ground-supporting screen 7 and the conveying device 9 are set at a certain angle with the front lower than the back, and both are set to be hollow.

[0038] In this embodiment, the power source is a motor 5 installed on the frame 11. The motor 5 is directly connected to the active bevel gear shaft 101 for power output, and the active bevel gear shaft 101 is meshed with the driven bevel gear shaft 102, so that the direction of the power can be changed to achieve power transmission. It should be noted that in actual applications, if a larger torque is required, the power source can also replace the motor 5 with an engine in a tractor, and the output shaft of the engine is directly connected to the active bevel gear shaft 101 to achieve high torque power output.

[0039] See also Figures 3 to 5 In this embodiment, a support wheel 22 is installed on the bracket body 21. The support wheel is limited in a groove formed by the recess of the mounting ring and cooperates with the mounting ring 37 installed on the drum body 34 to support the drum body 34 while enabling it to rotate axially. In order to transmit power to the drum body 34 to rotate it, a gear 38 is provided on one side of the gear ring 33 installed on the drum body 34. The gear 38 is meshed with the gear ring 33. A second bevel gear shaft 32 and a first bevel gear shaft 31 meshed with the second bevel gear shaft 32 are provided on one side of the gear 38. A second pulley 82 is provided on one side of the first bevel gear shaft 31. The second pulley 82 is connected to the first pulley 81 through a belt.

[0040] It should be supplemented that the plowshare assembly 6, the conveying device 9 and the roller body 34 are all equipped with pulleys on one side of the transmission shaft, and the pulleys are connected by belts to achieve power transmission.

[0041] Working principle: when the motor 5 starts working, the motor 5 drives the transmission component, thereby driving the first pulley 81 to rotate, and driven by the belt, the fourth pulley 84 and the second pulley 82 are driven to rotate. The rotation of the fourth pulley 84 drives the rotation of the third pulley 83 under the action of the belt, so that the plowshare assembly 6, the conveyor 9 and the drum body 34 in the whole device rotate at the same time. At this time, driven by the traction frame 1, the whole device moves forward. At the same time, the sickle-shaped plowshare 61 digs out the stubble in the soil, and the ground screen 7 picks up the stubble and pushes it onto the conveyor 9 for transmission. The device 9 transports the stubble to the entrance of the drum body 34. During this process, the ground support screen 7 and the conveying device 9 filter most of the loose soil. Then, the stubble is moved into the drum body 34 under the guidance of the conical guide plate 12. Under the rotation of the drum body 34, the stubble collides with the cone spikes 35 on the side wall of the drum body 34, so that the soil on the stubble is broken. Under the rotation of the drum body 34, the soil is filtered out, and then the stubble with soil removed is sent from the drum body 34 to the collection device under the transmission of the drum brush 36, completing the soil removal and recovery of the entire corn stubble.

[0042] In summary, the corn stubble soil removal and recovery device in the above-mentioned embodiment of the utility model mainly utilizes the collision between the stubble and the conical thorns on the side wall of the drum body to break the hard soil on the stubble, and at the same time, the stubble is transported to the collection box under the transmission of the drum brush, thereby realizing the stubble soil removal and recovery function.

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
