Description

A cleaning device for a gasoline-powered peanut harvester Technical Field

[0001] This utility model relates to the field of impurity removal technology for peanut harvesters, and more specifically, it relates to an impurity removal device for a gasoline engine-type peanut harvester. Background Technology

[0002] The peanut picking machine mainly consists of a frame, electric motor, transmission system, picking and separating mechanism, fan separation mechanism, fan cleaning mechanism, and vibration mechanism. During operation, the machine is driven by a gasoline engine and enters the picking system through the feeding inlet or automatic feeding platform. The rotating picking rods strike the peanuts to separate them from the stems. The peanuts after being separated from the stems fall into the collection box. The peanuts may contain small stems and other impurities.

[0003] Existing gasoline-powered peanut harvesters have a filter screen installed inside the collection box. Impurities in the peanuts fall through the filter screen to the bottom of the collection box, thus filtering them out. However, during the harvesting process, peanuts continuously fall into the collection box and accumulate on the top of the filter screen. Impurities are not easily removed from the bottom of the filter screen, resulting in poor impurity removal. Furthermore, it is inconvenient to remove the peanuts after impurity removal from the collection box, reducing its practicality. Summary of the Invention

The first motor drives the first rotating shaft to rotate. The side end of the impurity removal box has discharge ports corresponding to the two impurity removal troughs. A box cover is installed on the top of the impurity removal box, and a sealing mechanism is connected to the box cover at the position corresponding to the two discharge ports. Multiple push plates are connected to the first rotating shaft inside the two impurity removal troughs via multiple stirring plates. Two second connecting pipes are connected to the conveying mechanism, each communicating with one of the two impurity removal troughs. Solenoid valves are installed on both second connecting pipes to facilitate stirring of the peanuts inside the impurity removal troughs, preventing peanuts from accumulating on the filter screen and ensuring effective impurity removal.

[0008] The present invention is further configured such that the conveying mechanism includes a conveying pipe, a second motor is installed on the conveying pipe, a second rotating shaft is fixedly connected to one end of the output shaft of the second motor extending into the inside of the conveying pipe, a spiral blade is fixedly connected to the outside of the second rotating shaft, and a discharge pipe is connected to the upper side of the side end of the conveying pipe. The discharge pipe is connected to two second connecting pipes, so as to facilitate the conveying of peanuts inside the first collection box to the inside of the impurity removal tank.

[0009] The present invention is further configured such that the sealing mechanism includes two electric cylinders, both of which are installed on the top of the box cover. The telescopic rods of the two electric cylinders are fixedly connected to a sealing plate that cooperates with the discharge port at one end below the box cover, so as to facilitate sealing the discharge port.

[0010] The present invention is further provided that the top of the sealing plate is provided with a slope to prevent peanuts and impurities from accumulating on the top of the sealing plate.

[0011] The present invention is further configured such that a second collection box is connected to the peanut harvester body, and the second collection box is connected to two discharge ports through a third connecting pipe, which facilitates the collection of peanuts discharged from the impurity removal box.

The size of the discharge pipe is designed according to the usage requirements to facilitate the discharge of peanuts from the inside of the second collection box.

[0013] The present invention is further configured such that the bottom end of the impurity removal box is connected to a guide trough, so that the screened impurities fall through the guide trough to one side of the peanut harvester body.

[0014] The present invention is further configured such that the bottom surfaces of the inner ends of the first collection box and the second collection box are both inclined, so that the peanuts inside the first collection box can slide into the inner end of the first connecting pipe, and the peanuts inside the second collection box can slide into the side of the discharge pipe.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cleaning device for a gasoline engine-type peanut harvester, which has the following beneficial effects:

[0017] 1. The peanuts inside the first collection box are conveyed to the corresponding impurity removal tank by the conveying mechanism. Impurities in the peanuts are screened out through the mesh of the filter screen. The first motor drives the first rotating shaft, multiple stirring plates and pusher plates to rotate. The pusher plates push the peanuts at the bottom of the impurity removal tank. The multiple stirring plates stir the peanuts inside the impurity removal tank, making the peanuts roll inside the impurity removal tank, avoiding the peanuts from accumulating on the filter screen, and making it easier to screen out the impurities in the peanuts, so as to ensure the impurity removal effect.

[0018] 2. Two electric cylinders pull the sealing plate upwards, moving it to the upper side of the discharge port. The first motor drives the first rotating shaft, multiple stirring plates, and multiple pushing plates to rotate. The multiple pushing plates push the peanuts up. When the pushing plates push the peanuts to the upper side of the discharge port, the peanuts on the pushing plates will slide off the pushing plates into the interior of the discharge port, thus facilitating the timely removal of peanuts from the impurity removal tank.

[0019] 3. By setting up two impurity removal troughs, two second connecting pipes, two solenoid valves and two sealing mechanisms, during the process of discharging the peanuts after impurity removal from one impurity removal trough, the conveying mechanism transports the peanuts to be removed to the inside of another impurity removal trough, where the impurity removal operation is carried out. This ensures the continuity of peanut harvesting and impurity removal, and guarantees the efficiency of peanut harvesting. Attached Figure Description

[0029] Please refer to Figures 1-5. A cleaning device for a gasoline-powered peanut harvester includes a peanut harvester body 1, which is a gasoline-powered peanut harvester. The peanut harvester body 1 has a first collection box 2 for collecting peanuts. A conveying mechanism is installed on the side of the peanut harvester body 1, and the conveying mechanism is connected to the interior of the first collection box 2 via a first connecting pipe 3. A cleaning box 4 is installed on the peanut harvester body 1, and the cleaning box 4 has two cleaning grooves 5. The bottom of the cleaning box 4 is connected to two... Filter screens 6 are installed at the corresponding positions of the impurity removal troughs 5. A guide trough 27 is connected to the bottom of the impurity removal box 4, allowing the screened impurities to fall through the guide trough to one side of the peanut harvester body 1. The bottom of the guide trough 27 is fixedly connected to the peanut harvester. A first rotating shaft 7 is rotatably connected inside the impurity removal box 4. A first motor 8 is installed on the impurity removal box 4 to drive the first rotating shaft 7. Discharge ports 9 are provided at the side ends of the impurity removal box 4 at the corresponding positions of the two impurity removal troughs 5. A box cover 10 is installed on the top of the impurity removal box 4. A sealing mechanism is connected to each of the two discharge ports 9. Multiple push plates 12 are connected to the first rotating shaft 7 inside the two impurity removal tanks 5 through multiple stirring plates 11. Two second connecting pipes 13 are connected to the conveying mechanism, and the two second connecting pipes 13 are respectively connected to the two impurity removal tanks 5. Solenoid valves 14 are installed on the two second connecting pipes 13. A second collection box 23 is connected to the peanut picking machine body 1. The second collection box 23 is connected to the two discharge ports 9 through a third connecting pipe 24, which facilitates the collection of peanuts discharged from the impurity removal box 4. A discharge pipe 25 is connected to the bottom side of the second collection box 23. A valve 26 is installed on the discharge pipe 25. The size of the discharge pipe 25 is designed according to the usage requirements to facilitate the discharge of peanuts from the second collection box 23. The bottom surfaces of the first collection box 2 and the second collection box 23 are both inclined, which facilitates the peanuts in the first collection box 2 to slide into the first connecting pipe 3 and the peanuts in the second collection box 23 to slide into the side of the discharge pipe 25.

[0030] Specifically, the peanuts inside the first collection box 2 are conveyed to the corresponding impurity removal tank 5 by the conveying mechanism. Impurities in the peanuts are screened out through the mesh of the filter screen 6. The first motor 8 drives the first rotating shaft 7, multiple stirring plates 11, and pusher plates 12 to rotate. The pusher plates 12 push the peanuts at the bottom of the impurity removal tank 5, and the multiple stirring plates 11 stir the peanuts inside the impurity removal tank 5, making the peanuts roll inside the impurity removal tank 5, preventing the peanuts from accumulating on the filter screen 6, and facilitating the screening out of the peanuts, ensuring the impurity removal effect. The two electric cylinders 20 pull the sealing plate 21 upward, so that the sealing plate 21 is moved to the upper side of the discharge port 9. The first motor 8 drives the first rotating shaft 7, Multiple stirring plates 11 and multiple pushing plates 12 rotate, pushing peanuts up through the multiple pushing plates 12. When the pushing plates 12 push the peanuts to the upper side of the discharge port 9, the peanuts on the pushing plates 12 will slide off the pushing plates 12 and into the interior of the discharge port 9, thus facilitating the timely removal of peanuts from the impurity removal trough 5. By setting up two impurity removal troughs 5, two second connecting pipes 13, two solenoid valves 14 and two sealing mechanisms, during the process of discharging the peanuts after impurity removal from one impurity removal trough 5, the conveying mechanism transports the peanuts to be removed to the interior of another impurity removal trough 5 for impurity removal operations, ensuring the continuity of peanut harvesting and impurity removal, and ensuring the efficiency of peanut harvesting.

[0031] Please refer to Figure 5. The conveying mechanism includes a conveying pipe 15, on which a second motor 16 is installed. The output shaft of the second motor 16 extends into the inside of the conveying pipe 15 and is fixedly connected to a second rotating shaft 17. A spiral blade 18 is fixedly connected to the outside of the second rotating shaft 17. A discharge pipe 19 is connected to the upper side of the side of the conveying pipe 15. The discharge pipe 19 is connected to two second connecting pipes 13, which facilitates the conveying of peanuts inside the first collection box 2 to the inside of the impurity removal tank 5.

[0032] Specifically, the second motor 16 drives the second rotating shaft 17 and the spiral blade 18 to rotate. The rotation of the spiral blade 18 causes the peanuts inside the conveying pipe 15 to be conveyed to the upper side and discharged through the discharge pipe 19. The peanuts are then discharged into the corresponding impurity removal tank 5 through the corresponding second connecting pipe 13.

[0033] Please refer to Figure 4. The sealing mechanism includes two electric cylinders 20. Both electric cylinders 20 are installed on the top of the box cover 10. The telescopic rods of the two electric cylinders 20 extend to one end below the box cover 10 and are fixedly connected to a sealing plate 21 that cooperates with the discharge port 9. The top of the sealing plate 21 is provided with a slope 22 to prevent peanuts and impurities from accumulating on the top of the sealing plate 21.

[0034] Specifically, two electric cylinders 20 push the sealing plate 21 downwards, so that the bottom end of the sealing plate 21 contacts the bottom end of the discharge port 9, thereby sealing the discharge port 9 and preventing impurities in the peanuts from being discharged from the discharge port 9. The two electric cylinders 20 pull the sealing plate 21 upwards, so that the sealing plate 21 is moved to the upper side of the discharge port 9, making it easier for the peanuts to be discharged from the inside of the discharge port 9 to the outside of the impurity removal box 4.

[0035] In summary, when using the overall equipment:

[0036] Peanuts harvested by the peanut harvester body 1 fall into the first collection box 2. The peanuts inside the first collection box 2 slide down through the first connecting pipe 3 into the conveying pipe 15. The second motor 16 drives the second rotating shaft 17 and the spiral blades 18 to rotate. The rotation of the spiral blades 18 conveys the peanuts inside the conveying pipe 15 to the upper side and discharges them through the discharge pipe 19. The peanuts inside the discharge pipe 19 fall into the impurity removal trough 5 through the second connecting pipe 13 opened by the solenoid valve 14. At this time, the sealing mechanism inside the impurity removal trough 5 has blocked the discharge port 9. Simultaneously, the first motor 8 drives the first rotating shaft 7, multiple stirring plates 11, and the pusher plate 12 to rotate. The pusher plate 12 pushes up the peanuts at the bottom of the impurity removal trough 5, and the multiple stirring plates 11 stir the peanuts inside the impurity removal trough 5, causing them to roll inside. Impurities in the peanuts fall through the mesh of the filter screen 6 onto the guide trough 27 and then onto one side of the peanut harvester body 1. When it is necessary to remove impurities... When peanuts are discharged from the corresponding impurity removal tank 5, the discharge port 9 inside another impurity removal tank 5 is blocked by the sealing mechanism. Then, the solenoid valve 14 on the second connecting pipe 13 connected to it is closed, and another solenoid valve 14 is opened. The peanuts inside the discharge pipe 19 fall into the interior of another impurity removal tank 5 through another second connecting pipe 13. Impurity removal is carried out inside the other impurity removal tank 5. After being stirred for a period of time by multiple stirring plates 11 and multiple pusher plates 12, the sealing mechanism corresponding to the impurity removal tank 5 that needs to discharge peanuts stops blocking the corresponding discharge port 9. The first motor 8 drives the first rotating shaft 7, multiple stirring plates 11 and multiple pusher plates 12 to rotate. The peanuts are pushed up by multiple pusher plates 12. When the pusher plates 12 push the peanuts to the upper side of the discharge port 9, the peanuts on the pusher plates 12 will slide off the pusher plates 12 into the interior of the discharge port 9. The peanuts fall into the second collection box 23 through the third connecting pipe 24. The second collection box 23 collects the impurity-removed peanuts.

For all the fixed connections mentioned above, welding is preferred.
