DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 6 As shown, the present embodiment provides a wind-modified double-drum screen vibration separation cyperus oleifera harvesting device, comprising a cab 4, a paddle assembly 1 and a shovel tooth 2 are installed at the front end of the cab 4 in the direction of travel, an auger group 3 is provided at the rear side of the shovel tooth 2, a discharge bin 5 is installed at the rear side of the cab 4, a collection bin 8 is provided on one side of the discharge bin 5, and a wind-selected double-drum screening assembly 6 is provided between the discharge side of the auger group 3 and the collection bin 8.

[0026] The cockpit 4 is used to control the entire device. The paddle assembly 1 pulls up the cyperus rotundus, and the shovel teeth 2 are used to insert into the soil to shovel up the surface soil of the ground, so that the paddle assembly 1 can send the cyperus rotundus to the auger assembly 3. The auger assembly 3 continues to send the cyperus rotundus to the air selection double-drum screening assembly 6. After being screened by the air selection double-drum screening assembly 6, the cyperus rotundus is air-selected and screened. Since the air selection double-drum screening assembly 6 adopts two screening drums, the screening of the cyperus rotundus can be cleaner, reducing the subsequent workload.

[0027] A further optimization scheme is that the air selection double-drum screening component 6 includes a shell 601, in which at least one group of inner and outer screening cylinders 606 and outer screening cylinders 611 arranged inside the shell 601 are arranged, and the inner and outer screening cylinders 606 and 611 are inclined. The lower end of the inner screening cylinder 606 is located on the side close to the auger group 3, and the lower ends of the inner and outer screening cylinders 606 and 611 are provided with a blowing assembly, and the rotation directions of the inner and outer screening cylinders 606 and 611 are opposite. A feed port 604 is provided on the feed side of the inner screening cylinder 606, and a driving member is transmission-connected to the outer screening cylinder 611, and a reverse rotating connecting member is provided between the inner screening cylinder 606 and the outer screening cylinder 611, and a conveying assembly for transporting the material on the discharge side of the auger group 3 to the feed port 604 is provided on the top surface of the shell 601, and a gap is reserved between the outer side wall of the discharge port of the feed port 604 and the inner screening cylinder 606.

[0028] The screening particle size of the inner screening cylinder 606 is larger than that of the outer screening cylinder 611. The cyperus juncea mixed with straw fed through the feed port 604 enters the inner screening cylinder 606. Due to the wind force of the air blowing assembly, part of the straw is blown to the discharge bin 5 through the outer wall of the discharge port of the feed port 604 and the gap between the inner screening cylinder 606. Then, as the inner screening cylinder 606 rotates, it gradually moves to its lower end, passes through the bottom end of the inner screening cylinder 606, and falls to the outer screening cylinder (611). The outer screening cylinder (611) is also connected to the air blowing assembly. At this time, the impurities in the outer screening cylinder (611) are further blown to the discharge bin 5 under the action of wind force, thereby improving the screening effect of cyperus juncea.

[0029] According to a further optimized solution, the conveying assembly includes a feeding conveyor belt 603 installed on the top surface of the shell 601, a plurality of baffles are provided on the feeding conveyor belt 603, and the rotating shaft of the feeding conveyor belt 603 is driven by a feeding motor.

[0030] The rotation of the feeding motor drives the feeding conveyor belt 603 to run, and the feeding conveyor belt 603 feeds the cyperus oleifera on the discharge side of the auger group 3 into the feeding port 604, and then feeds it into the inner screening cylinder 606 through the feeding port 604.

[0031] In a further optimized solution, the air blowing assembly includes an air inlet pipe 602 connected to the lower end of the housing 601, and a blower is installed in the air inlet pipe 602. The operation of the blower can provide wind power for the screening of the inner screening cylinder 606 and the outer screening cylinder 611.

[0032] In a further optimized solution, the reverse rotation connector includes a connecting rod 609 fixedly connected to one side of the lower end of the housing 601, and the other end of the connecting rod 609 is rotatably connected to a meshing gear 610, which meshes between the outer side of the inner screening cylinder 606 and the inner side of the outer screening cylinder 611. The meshing gear 610 can make the outer screening cylinder 611 and the inner screening cylinder 606 rotate in different directions.

[0033] To further optimize the solution, the lower end of the inner screening cylinder 606 is fixedly connected to the inner cylinder support ring 613, and the inner cylinder support ring 613 is rotatably connected to the shell 601; the lower end of the outer screening cylinder 611 is fixedly connected to the outer cylinder support ring 605, the meshing gear 610 is meshed between the outer cylinder support ring 605 and the inner cylinder support ring 613, the high end of the inner cylinder support ring 613 is rotatably connected to the inner cylinder connecting ring 615, the inner cylinder connecting ring 615 is installed on the feed port 604, the feed port 604 is fixedly connected to the shell 601, the high end of the outer screening cylinder 611 is rotatably connected to the outer cylinder connecting ring 614, and the outer cylinder connecting ring 614 is fixedly connected to the shell 601.

[0034] According to a further optimized solution, the driving member includes a driving gear set 607 , which meshes with the outer side of the outer cylinder support ring 605 , and the input end of the driving gear set 607 is connected to a roller driving motor 608 , which is mounted on the shell 601 .

[0035] The rotation of the drum drive motor 608 can drive the driving gear set 607 to operate. The rotation of the driving gear set 607 drives the outer drum support ring 605 to rotate, and further drives the outer screening drum 611 to rotate. Under the action of the meshing gear 610, the inner drum support ring 613 rotates in the opposite direction, so that the inner screening drum 606 and the outer screening drum 611 rotate in different directions, and the rotation of the inner screening drum 606 and the outer screening drum 611 in different directions is realized through one power source.

[0036] In a further optimized solution, the inner wall of the outer screening cylinder 611 is fixedly connected with an inner thread leaf 612, and a clearance gap for waste to pass through is reserved between the inner contour of the inner thread leaf 612 and the inner screening cylinder 606. The arrangement of the inner thread leaf 612 can lift the material in the outer screening cylinder 611 from the lower end to the higher end, and then further send it into the collection bin 8.

[0037] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
