[0037] By Figures 1 to 3Provided is a separation and cleaning device for a peanut harvester. The separation and cleaning device 1 is installed on the main body of the peanut harvester, and the peanut harvester also includes functional structures such as a digging device, a conveying device, a soil separation device, and a fruit picking device. First, the digging device digs peanuts out of the ground, then the conveying device sends the peanuts into the soil separation device, the soil separation device separates the soil on the peanut fruits, and then the conveying device continues to convey them to the fruit picking device.

[0038] The separation and cleaning device 1 includes a frame 2, a sorting and conveying mechanism, a screening mechanism, a fruit conveying and harvesting mechanism, a transmission mechanism, and a stem conveying mechanism.

[0039] Given by Figures 2 to 4 First, the frame 2 is installed at the rear end of the peanut harvester, and the sorting and conveying mechanism is inclinedly installed at the front end of the frame 2. The sorting and conveying mechanism includes a driving shaft 6, two threaded rods 61, a follower shaft 63, four nuts 64, a conveyor belt 62, a plurality of conveying plates 65, and a falling prevention component.

[0040] Specifically, the driving shaft 6 is rotatably installed inside the frame 2, the two threaded rods 61 are respectively installed on both sides of the frame 2, the follower shaft 63 is installed between the two threaded rods 61, the four nuts 64 are respectively threadedly installed on the outer periphery of the two threaded rods 61, and the four nuts 64 respectively abut against the upper and lower sides of both ends of the follower shaft 63. The conveyor belt 62 is wound around the outer periphery of the driving shaft 6 and the follower shaft 63, and a plurality of conveying plates 65 are arranged on the outer surface of the conveyor belt 62. More specifically, the peanut fruits separated by the fruit picking device fall between the conveying plates 65 arranged on the surface of the conveyor belt 62, and the conveyor belt 62 conveys the peanut fruits.

[0041] More perfectly, the falling prevention component is installed inside the frame 2. The falling prevention component includes a winding cloth 7, a winding tube 71, two first adjusting plates 72, a pressing roller 73, two second adjusting plates 74, and two anti-leakage plates 75.

[0043] Depend on Figures 3 to 5 Then, the screening mechanism is installed inside the frame 2, and the screening mechanism is located on one side of the output end of the conveyor belt 62. The screening mechanism includes a screen 3, two swing arms 31, a drop hopper 32, multiple fruit baffles 34, a fruit leakage port 35, a driving swing arm assembly, and a fan assembly.

[0044] Specifically, the screen 3 is movably arranged inside the frame 2, the top ends of the two swing arms 31 are rotatably installed at the front end of the screen 3, and the bottom ends of the two swing arms 31 are rotatably installed on both sides of the frame 2, the drop hopper 32 is installed on the side of the screen 3 away from the swing arm 31, a plurality of fruit blocking plates 34 are obliquely arranged on the top end of the drop hopper 32, and one side of the plurality of fruit blocking plates 34 is installed on the side of the screen 3 away from the swing arm 31, and the fruit leakage port 35 is opened between two adjacent fruit blocking plates 34. For additional explanation, a guide plate inclined downward is installed on the side of the screen 3 close to the fruit leakage port 35, and small impurities such as dust fall into the guide plate from the mesh of the screen 3, and then flow to the ground along the inclined surface. More specifically, the upper surface of the fruit blocking plate 34 has a stepped structure, and the fruit leakage port 35 is larger than the mesh of the screen 3.

[0045] The driving swing arm assembly is installed between the frame 2 and the drop hopper 32 , and the driving swing arm assembly includes a driving shaft 4 , two eccentric wheels 41 , two swing rods 42 and two connecting rods 43 .

More specifically, the wind generated by the rotation of the fan blades 52 blows from the air outlet 53 towards the part of the fruit leakage port 35. During the vibration of the screen mesh 3, the wind blows away the impurities in the peanut fruits, realizing the separation of peanut fruits and impurities.

[0049] It is further explained that multiple fruit blocking plates 34 are inclined to avoid blowing away the peanut fruits when the wind force is too large, and can effectively limit the lifted peanut fruits. Since the impurities are light in mass, the height to which all impurities are lifted will be higher than the height of the fruit blocking plates 34, so the impurities can be blown away smoothly.

More specifically, a motor is externally connected to one side of the first transmission shaft 9, and the motor drives the first transmission shaft 9 to rotate.
