[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-position automatic unloading structure of a soybean harvester includes a conveying sleeve 1, a rotating gear 2 10 is fixedly installed at the lower end of the conveying sleeve 1, a rotating motor 3 is installed on the side of the conveying sleeve 1, and the rotating motor 3 is fixedly installed on the fixed frame 2. A rotating gear 1 9 is fixedly installed at the lower end of the shaft of the rotating motor 3, and the rotating gear 1 9 is meshed with the rotating gear 2 10. The rotating gear 2 10 is installed inside the fixed frame 2, and the fixed frame 2 is fixed to the lower end of the conveying sleeve 1. A support pipe 11 is fixedly connected below the fixed frame 2, and the support pipe 11 is fixedly installed on the bracket 4. The bracket 4 is fixedly installed at the rear of the harvester, and a conveying arm 6 is vertically installed at the upper end of the conveying sleeve 1, and an oil cylinder 5 is fixedly installed at the connection between the conveying sleeve 1 and the conveying arm 6. A discharge pipe 7 is fixedly installed at the other end of the conveying arm 6. When in use, the rotating motor 3 drives the rotating gear 1 9 fixedly connected to its shaft to rotate. Since the rotating gear 1 9 is meshed with the rotating gear 2 10, the rotating gear 2 10 rotates accordingly. Since the rotating gear 2 10 is fixedly connected to the conveying sleeve 1, the conveying sleeve 1 rotates with the rotation direction of the rotating gear 2 10. Since the conveying arm 6 is vertically installed on the upper end of the conveying sleeve 1, and the oil cylinder 5 is fixedly installed at the connection between the conveying sleeve 1 and the conveying arm 6, the conveying arm 6 can be lifted and lowered with the extension and retraction of the piston of the oil cylinder 5.
[0021] Please refer to the figure for details Figure 4 As shown, a support device 8 is fixedly installed on the top surface of the harvester near the conveying sleeve 1, and the support device 8 includes a fixed base 81, and the fixed base 81 is fixedly installed on the top surface of the harvester. A support rod 82 is fixedly installed above the fixed base 81, and a rotating bearing 83 is installed above the support rod 82. An electric cylinder 84 is fixedly installed above the rotating bearing 83, and a connecting block 85 is fixedly installed on the upper surface of the electric cylinder 84. The connecting block 85 is fixedly connected to a telescopic rod 86 on the side facing the conveying arm 6, and the other end of the telescopic rod 86 is fixedly connected to a cantilever 87, and a vertical end of the cantilever 87 is fixedly connected to a connecting ring 88. When in use, the connecting ring 88 is fixedly connected to the conveying arm 6. Therefore, when the conveying arm 6 rotates, the electric cylinder 84 installed below the connecting block 85 is fixedly installed on the rotatable rotary The connecting ring 88 of the connecting block 85 fixedly connected to the cantilever 87 through the telescopic rod 86 can rotate with the rotation of the conveying arm 6. When the conveying arm 6 rotates the connecting block 85, the telescopic rod 86 will be elongated accordingly, and when the conveying arm 6 rotates, the telescopic rod 86 will be shortened accordingly, so that the conveying arm 6 can rotate while supporting. When the piston rod of the oil cylinder 5 is extended, the conveying arm 6 fixedly connected thereto is driven to rise. Since the connecting block 85 connected to the connecting ring 88 through the telescopic rod 86 and the cantilever 87 is fixedly installed on the electric cylinder 84, the electric cylinder 84 is also raised when the conveying arm 6 is raised. When the piston rod of the oil cylinder 5 contracts, the conveying arm 6 also descends with the contracted piston rod, and the electric cylinder 84 fixedly installed under the connecting block 85 connected to the connecting ring 88 through the telescopic rod 86 and the cantilever 87 also descends accordingly.
[0022] Working principle: When in use, the rotating motor 3 runs and drives the rotating gear 1 9 fixedly connected to its shaft to rotate. Since the rotating gear 1 9 is meshed with the rotating gear 2 10, the rotating gear 2 10 rotates accordingly. Since the rotating gear 2 10 is fixedly connected to the conveying sleeve 1, the conveying sleeve 1 rotates with the rotation direction of the rotating gear 2 10. Since the conveying arm 6 is vertically installed on the upper end of the conveying sleeve 1, and the oil cylinder 5 is fixedly installed at the connection between the conveying sleeve 1 and the conveying arm 6, the conveying arm 6 can be lifted and lowered with the extension and contraction of the piston of the oil cylinder 5. When the piston rod of the oil cylinder 5 is extended, the conveying arm 6 fixedly connected to it is driven to rise. Since the connecting block 85 connected to the connecting ring 88 of the cantilever 87 through the telescopic rod 86 is fixedly installed on the electric cylinder 84, the electric cylinder 84 is also lifted when the conveying arm 6 is raised. When the piston rod of the oil cylinder 5 contracts, the conveying arm 6 also descends with the contracted piston rod, and the electric cylinder 84 fixedly installed under the connecting block 85 connected to the connecting ring 88 of the cantilever 87 through the telescopic rod 86 also descends.
