Abstract
Description
Technical Field
[0001] This utility model relates to the field of peanut harvesting machines, and more specifically, it relates to a high-efficiency separation mechanism for peanut harvesting machines. Background Technology
[0002] Peanuts are very common in people's lives and industrial production. They are rich in nutrients and can also be pressed for oil, which greatly facilitates people's lives and industrial production. After the peanut harvest, the connection between the peanut fruit and the peanut vine is broken by a peanut harvester. However, the peanut fruit and the peanut vine are still mixed together, so a separation mechanism is needed to separate the peanut from the peanut vine. Since a lot of soil adheres to the peanut after harvest, the soil also needs to be removed from the peanut while separating the peanut from the peanut vine to facilitate the harvest. Because both the peanut and the peanut vine are covered with soil, the soil will be broken up and scattered into the surrounding environment during separation, resulting in a lot of dust in the operating environment, making the environment harsh and inconvenient for operators.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a high-efficiency separation mechanism for a peanut harvester, which has the following beneficial effects:
[0017] 1. This utility model, by setting up a roller, when separating peanuts from peanut vines, the mixture of peanuts and peanut vines is conveyed to the feed hopper by a conveying device, and then fed into the roller through the feed hopper. Through the transmission structure set on the main frame by the motor, the rotating wheel is driven to rotate, thereby causing the roller to roll. The rotation of the roller separates the lighter peanuts from the heavier peanut vines. The peanuts enter the separating box through the through hole opened on the roller and are discharged from the discharge port opened on the separating box. The peanut vines enter the unloading hopper through the discharge port opened at the other end of the roller, thereby realizing the separation of peanuts from peanut vines and facilitating the harvesting of peanuts.
[0018] 2. This utility model, by setting up a spray structure, separates peanuts from peanut vines while connecting the connection port on the water tank to an external water supply device. The external water pump installed in the water tank pumps water into the spray nozzles, and the water is sprayed out into the drum to wash away the soil on the peanuts, thereby separating the adhering soil from the peanut shells. This facilitates the removal of soil, making it easier to harvest peanuts and reducing the steps required for subsequent peanut production.
[0019] 3. This utility model, by setting up a shielding structure, prevents soil from the peanuts from being thrown into the surrounding environment during the rotation of the drum. While the dust is suppressed by the spray structure, the shielding plate and the extension plate work together to shield the soil or peanuts, preventing the peanuts from being thrown into the surrounding environment. When using the shielding structure, the extension plate is pulled out of the placement groove set on the shielding plate. The extension plate is fixed at the required height by the positioning holes and bolts on the shielding plate and the extension plate, thereby increasing the shielding range of the shielding plate. When it is necessary to lower the entire shielding structure, the locking block is rotated, and the shielding plate is lowered by the rotational connection between the locking block and the fixing frame, so as to facilitate the adjustment of the shielding structure as needed.

[0029] Please see Figure 1-5 A high-efficiency separation mechanism for a peanut harvester includes a main frame 1 and a drum 2. The drum 2 is mounted on the main frame 1. A support frame 3 is fixedly mounted on one end of the main frame 1. A feed inlet 4 is mounted on one end of the drum 2. A feed hopper 5 is fixedly mounted on the support frame 3. The feed hopper 5 is connected to the feed inlet 4. A discharge outlet 6 is mounted on the other end of the drum 2.
[0030] A fixed frame 7 is fixedly installed on the upper end of the main frame 1. A spray structure is installed on the fixed frame 7. The spray structure includes a water tank 8, a spray nozzle 9 and a connection port 10. The water tank 8 is fixedly installed on the fixed frame 7. A shielding structure is installed on the fixed frame 7. The shielding structure includes a shielding plate 11, an extension plate 12 and a locking block 13. Two sets of shielding structures are provided.
[0031] In this embodiment, the main structure of the entire separation mechanism is formed by the cooperation of the main frame 1 and the roller 2. The feed hopper 5 facilitates the mixing of peanuts and peanut vines into the roller 2, and the discharge port 6 facilitates the release of peanut vines.
[0032] More specifically, a spray structure is used to separate the soil from the peanuts, and a shielding structure is used to prevent the peanuts and soil from being thrown out.
[0033] Please see Figures 1-5 As an implementation method for separating peanuts from peanut vines: a rotating wheel 14 is provided on the main frame 1, and the rotating wheel is rotatably connected to the main frame 1. A motor 15 is fixedly provided on the main frame 1. Multiple sets of motors 15 and rotating wheels 14 are provided. A through hole 16 is provided on the roller 2. The through hole 16 on the roller 2 is provided with a strip. A separator box 17 is fixedly provided at the lower end of the main frame 1. A discharge port 18 is provided on the separator box 17. Multiple discharge ports 18 are provided. A discharge hopper 23 is provided at the side end of the roller 2 at the opening position of the discharge port 6. A support leg 24 is provided on the discharge hopper 23. The support leg 24 is fixedly connected to the discharge hopper 23.
[0034] Specifically, when separating peanuts from peanut vines, the mixture of peanuts and peanut vines is conveyed to the feed hopper 5 via a conveying device. The mixture then enters the roller 2 via the feed hopper 5. Through the transmission structure set on the main frame 1, the motor 15 drives the rotating wheel 14 to rotate, thereby causing the roller 2 to roll. The rotation of the roller 2 separates the lighter peanuts from the heavier peanut vines. The peanuts enter the separator box 17 through the through hole 16 on the roller 2 and are discharged from the discharge port 18 on the separator box 17. The peanut vines enter the unloading hopper 23 through the discharge port 6 at the other end of the roller 2, thus achieving the separation of peanuts from peanut vines.
[0035] Please refer to Figure 1-5 As an implementation method for spraying and protecting peanuts and peanut vines during the separation process: the connection port 10 is fixedly installed on the water tank 8, the spray nozzle 9 is fixedly installed on the fixed frame 7, and multiple spray nozzles 9 are provided. The spray nozzles 9 are connected to the water tank 8. The baffle plate 11 has a placement groove 19, the extension plate 12 is installed in the placement groove 19, the locking block 13 is installed on the fixed frame 7, and multiple locking blocks 13 are provided. The locking blocks 13 are rotatably connected to the fixed frame 7, and the locking blocks 13 and the fixed frame 7 are damped. Rotating columns 20 are fixedly installed at both ends of the baffle plate 11. Rotating holes 21 are provided on the fixed frame 7. The rotating columns 20 and the rotating holes 21 cooperate with each other and are rotatably connected. Positioning holes 22 are provided on both the baffle plate 11 and the extension plate 12. Multiple positioning holes 22 are provided. The positioning holes 22 are provided in the positioning holes 22. The positioning holes 22 on the baffle plate 11 are bolted to the positioning holes 22 on the extension plate 12.
[0036] Specifically, while separating the peanuts from the peanut vines, the connection port 10 on the water tank 8 is connected to an external water supply device. The external water pump in the water tank 8 pumps water into the spray nozzle 9, and the water is sprayed out from the spray nozzle 9, thus spraying into the roller 2 to wash away the soil on the peanuts, thereby separating the adhering soil from the peanut shells, making it easier to remove the soil. Through the positioning holes 22 on the baffle plate 11 and the extension plate 12 and the cooperation of bolts, the extension plate 12 is fixed at the required height, thereby increasing the coverage of the baffle plate 11. When the roller 2 rotates, the soil on the peanuts will be scattered into the surrounding environment. While the spray structure reduces dust, the baffle plate 11 and the extension plate 12 cooperate to cover the soil or peanuts, preventing the peanuts from being thrown into the surrounding environment.
[0037] In summary, when using it as a whole:
[0038] When separating peanuts from peanut vines, the mixture of peanuts and peanut vines is conveyed to the feed hopper 5 via a conveying device. The mixture then enters the drum 2 through the feed hopper 5. The motor 15 and the transmission structure on the main frame 1 drive the rotating wheel 14 to rotate, which in turn causes the drum 2 to roll. The rotation of the drum 2 separates the lighter peanuts from the heavier peanut vines. The peanuts enter the separator box 17 through the through hole 16 on the drum 2 and are discharged from the discharge port 18 on the separator box 17. The peanut vines enter the unloading hopper 23 through the discharge port 6 at the other end of the drum 2, thus achieving the separation of peanuts from peanut vines.
[0039] While separating the peanuts from the peanut vines, the connection port 10 on the water tank 8 is connected to an external water supply device. The external water pump in the water tank 8 pumps water into the spray nozzle 9, and the water is sprayed out from the spray nozzle 9, thus spraying into the roller 2 to wash away the soil on the peanuts, thereby separating the sticky soil from the peanut shells and making it easier to remove the soil. The extension plate 12 is fixed at the required height by the positioning holes 22 on the baffle plate 11 and the extension plate 12 and the cooperation of bolts, thereby increasing the coverage of the baffle plate 11. As the roller 2 rotates, the soil on the peanuts will be scattered into the surrounding environment. While the spray structure reduces dust, the baffle plate 11 and the extension plate 12 work together to cover the soil or peanuts, preventing the peanuts from being thrown into the surrounding environment.
