[0002] The fruit picking drum in the peanut harvester is a key working component, which is mainly responsible for separating the peanut fruits from the plants. This component generates strong centrifugal force through its own high-speed rotation, causing the peanut vines to be continuously impacted and rubbed in the drum, thereby effectively knocking the ripe fruits off the vines, achieving fast and efficient harvesting operations.

[0003] For example, the patent specification of the existing Chinese patent (publication number: CN212138450U) discloses a fruit picking mechanism for a peanut harvester, which belongs to the technical field of peanut harvesters. It includes a frame, a fruit picking roller and a fruit picking groove, the fruit picking roller includes a fruit picking roller drum, and the fruit picking roller moving teeth are evenly distributed on the cylindrical surface of the fruit picking roller drum. The fruit picking roller drum is supported on the left and right sides of the frame through the left and right ends of the fruit picking roller drum rotating shaft, respectively, and the fruit picking roller is provided with a fruit picking roller transmission connection component. The fruit picking groove includes a fruit picking groove body and fixed teeth, the fruit picking groove body is located at the bottom of the fruit picking roller, and the left side wall of the fruit picking groove body and the right side wall of the fruit picking groove body are fixed on the left and right sides of the frame respectively, and at least one row of fixed teeth is provided on the bottom wall of the fruit picking groove body, and the fixed teeth are arranged at intervals from the left side wall of the fruit picking groove body to the right side wall of the fruit picking groove body along the axial direction of the fruit picking roller drum rotating shaft, and the gaps between the moving teeth and the fixed teeth of each fruit picking roller of the fruit picking roller correspond to each other.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed fruit picking roller for peanut harvesters has the following problems: during the peanut harvesting process, since the peanut stems and vines often carry debris such as soil, residual leaves and other plant fragments, these debris are easily caught by the blade teeth and attached to the surface of the roller during the fruit picking operation, which not only affects the normal striking and separation effect of the blade teeth on the peanut fruits, but may also cause blockage between the blade teeth and the fruit picking groove. In view of this, a fruit picking roller for a peanut harvester is provided to overcome the above-mentioned defects. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , Figure 4 As shown, this embodiment provides a technical solution: a fruit picking roller for a peanut harvester, comprising a bracket 1, a cleaning component 2 is arranged on the top of the bracket 1, and a transport component 3 is arranged on the bottom of the cleaning component 2;

[0027] The transport assembly 3 includes a protective frame 31, a roller 32 is disposed in the inner cavity of the protective frame 31, a first support plate 33 is disposed in the inner cavity of the roller 32, a spring tooth 34 is disposed on the side of the first support plate 33, and one end of the spring tooth 34 passes through the roller 32 and extends to the outside of the roller 32;

[0028] A first slide groove 35 is provided on the surface of the spring tooth 34, and a support rod 36 is fixedly connected to the side of the first support plate 33. The end of the support rod 36 away from the first support plate 33 passes through the inner cavity of the first slide groove 35 and extends to the outside of the spring tooth 34, and is slidably connected to the inner cavity of the first slide groove 35. A second slide groove 37 is provided on the surface of the drum 32, and a scraper 38 is provided on the side of the spring tooth 34. A feeding port is provided on one side of the drum 32, and the other side of the drum 32 is rotatably connected to the inner wall of the protective frame 31 through a bearing. By providing the protective frame 31, the peanut vines can be prevented from falling when the transport component 3 is running. By providing a spiral structure on the surface of the drum 32, the movement trajectory of the peanut vines can be limited, thereby driving the drum 32 to rotate. After the peanut vines are picked, the hub motor 52 is stopped, the motor 53 is started, and the motor 53 and The transmission rod 54 cooperates to drive the first support plate 33 to rotate. When the output shaft of the motor 53 rotates forward, the first support plate 33 can be driven to rotate through the transmission rod 54. The rotation of the first support plate 33 can drive the support rod 36 to rotate. When the support rod 36 rotates, it can drive the spring tooth 34 to move along the inner cavity of the second slide groove 37 toward the inner cavity of the drum 32. The first slide groove 35, the support rod 36 and the second slide groove 37 cooperate to limit the movement trajectory of the spring tooth 34. Similarly, when the output shaft of the motor 53 is reversed, it can drive the spring tooth 34 to move to the outside of the drum 32, thereby realizing the extension and retraction of the spring tooth 34. By arranging a scraper 38 on the surface of the drum 32, the peanut vines and soil attached to the surface of the spring tooth 34 can be removed when the spring tooth 34 shrinks toward the inner cavity of the drum 32, thereby achieving the effect of cleaning the spring tooth 34.

[0029] Further, such as Figure 1 , Figure 4 As shown: a power component 5 is arranged on the side of the transport component 3, and the power component 5 includes a shell 51. A wheel hub motor 52 is arranged in the inner cavity of the shell 51. A motor 53 is arranged on the side of the inner wall of the protective frame 31. The output shaft of the motor 53 is fixedly connected with a transmission rod 54. One end of the wheel hub motor 52 away from the output shaft is fixedly connected to the side of the inner wall of the shell 51. The output shaft of the wheel hub motor 52 is rotatably connected to the side of the protective frame 31 through a bearing. The other end of the motor 53 away from the output shaft is fixedly connected to the bearing. By setting the shell 51, the wheel hub motor 53 can be protected. When the output shaft of the motor 53 rotates, it can drive the wheel hub motor 52 to rotate through the bearing. When the wheel hub motor 52 rotates, it can drive the transmission rod 54 to rotate.

[0030] In the above scheme, there is still a problem that when the peanut vine is rolled in, debris will adhere to the surface, causing blockage, such as Figure 1 , Figure 2 As shown: the cleaning component 2 includes a mounting block 21, and a brush 22 is arranged on the side of the mounting block 21. By setting the mounting block 21, the brush 22 can be supported to ensure its stability during operation. By setting the brush 22, debris on the peanut vines can be cleared when the transport component 3 is running.

[0031] The above scheme still has the problem that when picking the peanut vines, the sundries on the rhizomes and the peanuts will be mixed together, such as Figure 1 , Figure 3 As shown: a screening component 4 is arranged at the bottom of the transport component 3, and the screening component 4 includes a second support plate 41, a filter screen 44 is arranged on the side of the second support plate 41, and vibration motors 46 are arranged on both sides of the filter screen 44. A third slide groove 42 is opened on the side of the second support plate 41, and sliders 43 are fixedly connected on both sides of the filter screen 44. One end of the slider 43 away from the filter screen 44 extends to the inner cavity of the third slide groove 42 and is slidably connected to the inner cavity of the third slide groove 42. A spring 45 is arranged at the bottom of the slider 43. By setting the filter screen 44, the filter screen 44 can be removed. The fallen soil and peanuts are collected, and the filter 44 can be vibrated by setting a vibration motor 46. The filter 44 can be supported by setting a slider 43. When the vibration motor 46 is running, the filter 44 can be driven to vibrate. When the filter 44 vibrates, the third slide groove 42 and the slider 43 cooperate to limit the movement trajectory of the filter 44. The spring 45 is provided to buffer the vibration. The vibration motor 46 and the filter 44 cooperate to screen the fallen debris and peanuts, so that the peanuts can be collected.

[0032] Working principle:

[0033] like Figure 1-4 As shown, first, the peanut vines are transported in from the feeding port, and the hub motor 52 is started. The output shaft of the hub motor 52 rotates forward, thereby driving the drum 32 to rotate. When the drum 32 rotates, the spring teeth 34 can drive the peanut vines to move along the spiral structure on the surface of the drum 32 toward the discharge port of the drum 32. When the peanut vines move toward the discharge port, the cleaning component 2 set on the top of the bracket 1 can clean the debris attached to the surface of the peanut vines, and the debris and peanuts fall into the top of the filter screen 44 together, and the vibration motor 46 is started. The vibration motor 46 cooperates with the filter screen 44 to screen the debris and peanuts. After screening, the peanuts fall into the collection box and are picked. After the fruit picking is finished, the hub motor 52 is stopped and the motor 53 is started. When the output shaft of the motor 53 rotates forward, the first support plate 33 can be driven to rotate through the transmission rod 54. When the first support plate 33 rotates, the support rod 36 can be driven to rotate. The support rod 36, the spring tooth 34 and the first slide groove 35 cooperate to drive the spring tooth 34 to shrink into the inner cavity of the drum 32. When the spring tooth 34 shrinks into the inner cavity of the drum 32, the second slide groove 37 can scrape off the debris attached to the surface of the spring tooth 34, thereby cleaning the spring tooth 34. Similarly, the output of the motor 53 is reversed, and the spring tooth 34 moves to the outside of the drum 32 to continue the next fruit picking.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
