Description

Technical Field

[0001] The present invention relates to the technical field of peanut harvesters, and particularly to an automatic impurity removal and material distribution device for intelligent agricultural machinery. Background Art

[0002] A peanut harvester refers to a crop harvesting machine that completes operations such as digging fruits, separating soil, laying strips, picking up, fruit picking, and cleaning during the peanut harvesting process. Due to the uneven growth of peanut vines, some overly short or inclined peanut vines are often not harvested, resulting in a reduction in yield.

[0003] To solve the above problems, a peanut vine separation device for peanut harvesting with the publication number CN112449837B includes a bottom plate. On the left and right sides of the middle part of the upper surface of the bottom plate, special-shaped support plates are respectively fixedly connected. Inside the special-shaped support plates, two fruit picking shafts that cooperate with a chain and can rotate and move up and down are installed. Since the stems of peanut fruits are of different lengths, peanut fruits with short stems can be realized by the fruit picking shaft that rotates inward. When encountering peanut fruits with long stems, by rotating and moving up and down the two fruit picking shafts, some longer peanut fruits can be picked, thus achieving comprehensive picking.

[0004] However, we found in actual use that although the peanut fruits with long and short stems can be picked by rotating and moving up and down the fruit picking shaft, during actual fruit picking, the positions of peanut fruits are extremely complex. For some peanut fruits with long stems, there are also a small number of peanut fruits with short stems remaining on them. This makes it impossible to process the peanut fruits above when the fruit picking shaft is in the lower position, thereby reducing the fruit picking rate.

[0005] Therefore, we propose an automatic impurity removal and material distribution device for intelligent agricultural machinery. Summary of the Invention

[0013] In some embodiments, the first driving member includes a first mounting bracket and a second mounting bracket arranged on the harvesting body.

Detailed implementation manners

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1 - 9 , the present invention provides a technical solution: An automatic impurity removing and material distributing device for an intelligent agricultural machine, including a harvesting body 1. The harvesting body 1 includes a bottom plate, a chain, a toothed clamping plate, a leakage plate, a placing plate and other structures in the comparative document, which are common existing technologies and will not be elaborated here; A material distributing roller 2 is arranged on the harvesting body 1. A switching mechanism 3 for driving the material distributing roller 2 to rotate from a horizontal state to a vertical state is arranged on the harvesting body 1. A first driving member 6 for driving the horizontally placed material distributing roller 2 to work is arranged on the harvesting body 1. A second driving member 7 for driving the vertically placed material distributing roller 2 to work is arranged on the harvesting body 1. The peanut fruit harvesting steps are as follows: When the harvested fruits are upright peanuts (the plants are arranged neatly and the pods are concentrated) or short-stemmed whisker peanuts (the fruit stalks are short and hard), the material distributing roller 2 is adjusted to a horizontal state for operation. At this time, the axis of the material distributing roller 2 is consistent with the advancing direction of the harvesting body 1. The peanuts are conveyed through the chain and the toothed clamping plate. When they are sent to the material distributing roller 2, the rotating directions of the two sides of the material distributing roller 2 are opposite, and both are towards the peanut side. The impact force generated when the material distributing roller 2 rotates can separate the stalks and the pods. The separated pods fall onto the placing plate at the bottom, while the stalks are continuously conveyed backward along with the chain and the toothed clamping plate. At this time, the peanuts are continuously fed and move axially along the material distributing roller 2, ensuring uniform force, high threshing efficiency, and accurate peeling of the pods by forward impact, reducing missed picking; When the harvested fruits are trailing peanuts (the stems and vines are prostrate and intertwined) or long-stemmed whisker peanuts (the fruit stalks are long), the material distribution roller 2 is adjusted to a vertical state for operation. At this time, the axis of the material distribution roller 2 is perpendicular to the advancing direction of the harvesting body 1. The peanuts are conveyed through a chain and a toothed splint. When they are sent to the material distribution roller 2, the rotating directions of the two material distribution rollers 2 on both sides are opposite, and both are towards the peanut side. The impact force generated when the material distribution roller 2 rotates can separate the stalks and pods. The separated pods fall onto the bottom receiving plate, while the stalks are continuously conveyed backward along with the chain and the toothed splint. At this time, both the upper and lower parts of the long-stemmed whisker peanuts are within the impact range of the material distribution roller 2, ensuring that the small remaining short-stemmed whisker peanuts on them are also separated simultaneously. At this time, the peanuts are fed into the material distribution roller 2, and this rotation can effectively untangle the stems and vines and reduce blockages. A plurality of the material distribution rollers 2 are provided, and every two of the plurality of material distribution rollers 2 form a group. A plurality of stirring rods 8 are provided on each of the material distribution rollers 2. The stirring rods 8 are all in an L-shaped structure. In this solution, the material distribution roller 2 is designed into three groups, and the number of stirring rods 8 on each group is different. Among them, the number of stirring rods 8 on the middle group of material distribution rollers 2 is the largest, the number of stirring rods 8 on the frontmost material distribution roller 2 along the advancing direction of the harvesting body 1 is the smallest, and the number of stirring rods 8 on the rearmost material distribution roller 2 along the advancing direction of the harvesting body 1 is in the middle; The stirring rod 8 is designed with an obtuse contact surface. In this solution, an L-shaped round rod design is adopted, which can reduce the instantaneous impact force on the pods and separate the fruit pods through a rubbing force rather than a hard impact. A rubber layer can be provided on the outer side of the stirring rod 8 to further improve the protection of the peanuts; the L-shaped opening forms a non-closed channel, and the stalks will naturally slip off as the stirring rod 8 rotates, reducing entanglement and blockage, especially suitable for the treatment of the prostrate stalks of trailing peanuts; In addition, the adoption of the L-shaped stirring rod 8 design also has an eddy current effect. When the stirring rod 8 rotates, a spiral air flow is generated, and the light crushed stems and leaves are carried away from the threshing area by the air flow, reducing the subsequent cleaning load.

[0022] The switching mechanism 3 includes a plurality of rotating brackets 31 provided on the harvesting body 1. The material distribution rollers 2 are respectively rotatably provided on the rotating brackets 31. A lifting member 4 for lifting adjustment is provided on the harvesting body 1. Power transmission members 5 are provided on the rotating brackets 31. The rotating brackets 31 are of a special-shaped structure. Its main body is a U-shaped frame body with a connecting rod body provided at the bottom. The U-shaped frame body and the connecting rod body are fixedly connected. This fixed connection can be achieved by bolt fixing or welding fixing, without limitation; The lifting member 4 includes a plurality of first electric push rods 41 arranged on the harvesting body 1. The plurality of first electric push rods 41 are divided into two groups. A cleaning support plate body 42 is arranged at the top of each group of first electric push rods 41. The support plate body is of a bent structure and is integrally formed. This not only ensures the normal transmission of the second driving member 7 and the switching mechanism 3, but also is conducive to the normal falling of peanut fruits. In addition, traditional welding or bolt connection will cause stress concentration at the joint, reducing the fatigue life. Integral forming distributes the stress evenly through the continuous metal streamline, eliminates the stress concentration point, and greatly improves the anti-deformation ability; The transmission member 5 includes an output gear 51 arranged at one end of the material distribution roller 2 extending to the outside of the rotating bracket 31. A transmission gear 52 meshing with the output gear 51 is rotatably arranged on the rotating bracket 31. In the solution, the plurality of output gears 51 are the same, and the plurality of transmission gears 52 are also the same. The only difference is the installation position of the transmission gear 52. By different installation positions of the transmission gear 52, it is adapted to different sizes of the first driving gear 65 and the second driving gear 75, so as to realize different rotation speeds of different material distribution rollers 2. Among them, the rotation speed of the group of material distribution rollers 2 in the middle is the fastest, the rotation speed of the material distribution roller 2 at the frontmost in the forward direction of the harvesting body 1 is the slowest, and the rotation speed of the material distribution roller 2 at the rearmost in the forward direction of the harvesting body 1 is in the middle. The principle of this design is that the fewer the number of teeth of the driving gear, the lower the output rotation speed; the more the number of teeth of the driving gear, the higher the output rotation speed. With this design, the peanuts will pass through three groups of material distribution rollers 2 with different rotation speeds in sequence; The three material distribution rollers 2 are named the first-stage roller, the second-stage roller and the third-stage roller in sequence from the front to the back along the forward direction of the harvesting body 1. Among them, the first-stage roller has the slowest rotation speed, realizing the preliminary separation of peanut fruits and being able to separate the connection between the stalk and the pod. The second-stage roller has the fastest rotation speed, strengthening the separation effect of peanut fruits and being able to realize the separation of most fruits through the impact force (kneading force) of high-speed rotation. The third-stage roller has a rotation speed in the middle, being able to complete the final work of fruit separation, avoiding the residue of remaining fruits and improving the picking rate of fruits. The number of the poking rods 8 on the three material distribution rollers 2 is also designed accordingly; A first driving motor 9 is arranged on each of the cleaning support plate bodies 42. A plurality of fixed shafts 10 are rotatably arranged on the cleaning support plate bodies 42. Any one of the fixed shafts 10 is connected to the first driving motor 9. The plurality of rotating brackets 31 are respectively arranged on the fixed shafts 10, and the plurality of fixed shafts 10 are connected by belt transmission. Pulley wheels are arranged on the fixed shafts 10, and the pulley wheels are connected by belts. And the pulley wheel in the middle can be driven by the pulley wheels on both sides, which is a common structure in the prior art and will not be elaborated here.

[0023] The first driving member 6 includes a first mounting bracket 61 and a second mounting bracket 62 provided on the harvesting body 1. Two shifting brackets 63 are slidably provided on each of the first mounting bracket 61 and the second mounting bracket 62. The shifting brackets 63 on the first mounting bracket 61 and the adjacent shifting brackets 63 on the second mounting bracket 62 form a group. A driving shaft 64 is rotatably provided between each group of the shifting brackets 63. A plurality of first driving gears 65 are provided on the driving shaft 64. The first driving gears 65 are respectively engaged with the adjacent transmission gears 52. A second driving motor 66 connected to the driving shaft 64 is provided on the shifting bracket 63. A lead screw 67 is rotatably provided on the first mounting bracket 61. The two shifting brackets 63 on the first mounting bracket 61 are threadedly connected to both sides of the lead screw 67. A third driving motor 68 is provided on the first mounting bracket 61; When the third driving motor 68 is started, it drives the lead screw 67 to rotate. The lead screw 67 drives the shifting brackets 63 on both sides to slide on the first mounting bracket 61 to both sides. At this time, the first driving gears 65 and the transmission gears 52 are disengaged, and the rotating bracket 31 can rotate normally without interference with the first driving gears 65. Similarly, the third driving motor 68 can be used to control the lead screw 67 to reset the shifting brackets 63.

[0024] The second driving member 7 includes a plurality of second electric push rods 71 provided on the harvesting body 1. The plurality of second electric push rods 71 are divided into two groups. A lifting bracket 72 is provided on each group of the second electric push rods 71. A fourth driving motor 73 is provided on the lifting bracket 72. A plurality of mounting shafts 74 are rotatably provided on the lifting bracket 72. A plurality of second driving gears 75 are provided on the plurality of mounting shafts 74. The plurality of mounting shafts 74 are connected by belt drive. Pulley wheels are provided on the mounting shafts 74 and are connected by belts. The pulley wheel located in the middle can be driven by the pulley wheels on both sides, which is a common existing structure and will not be elaborated here. The second driving gears 75 are respectively engaged with the adjacent transmission gears 52; When the second electric push rod 71 is started, it drives the lifting bracket 72 to descend. Through this adjustment, the engagement between the second driving gears 75 and the transmission gears 52 can be cancelled, and the rotating bracket 31 can rotate normally without interference with the second driving gears 75. Similarly, the lifting bracket 72 can be reset by the second electric push rod 71. When in use, when the harvested fruits are upright peanuts (the plants are neatly arranged and the pods are concentrated) or short-stemmed whisker peanuts (the fruit stalks are short and hard), the feeding roller 2 is adjusted to a horizontal state for operation. At this time, the axis of the feeding roller 2 is consistent with the advancing direction of the harvesting body 1. The specific adjustment steps are as follows: The second electric push rod 71 starts and drives the lifting bracket 72 to descend. Through this adjustment, the engagement between the second driving gear 75 and the transmission gear 52 can be cancelled, and the rotating bracket 31 can rotate normally without interference with the second driving gear 75. The third driving motor 68 starts and drives the lead screw 67 to rotate. The lead screw 67 drives the displacement brackets 63 on both sides to slide on the first mounting bracket 61 towards both sides. At this time, the engagement between the first driving gear 65 and the transmission gear 52 is cancelled, and the rotating bracket 31 can rotate normally without interference with the first driving gear 65; The first driving motor 9 starts and drives multiple fixed shafts 10 to rotate through belt transmission, thereby realizing the normal rotation of multiple rotating brackets 31. At this time, the feeding drums 2 are in a horizontal state and there is a certain distance between them. Then the third driving motor 68 starts again and drives the lead screw 67 to rotate. The lead screw 67 drives the displacement brackets 63 on both sides to slide towards the central position on the first mounting bracket 61. At this time, the first driving gear 65 and the transmission gear 52 are engaged. Finally, starting the second driving motor 66 can drive the driving shaft 64 to rotate. The driving shaft 64 drives the first driving gear 65 to rotate. The first driving gear 65 drives the transmission gear 52 to rotate. The transmission gear 52 drives the output gear 51 and the feeding drums 2 to rotate; The peanuts are conveyed through a chain and a toothed splint. When they are sent to the feeding drums 2, the rotation directions of the feeding drums 2 on both sides are opposite and both are towards the peanut side. The impact force generated when the feeding drums 2 rotate can separate the stalks and pods. The separated pods enter the bottom holding plate, while the stalks are continuously conveyed backward along with the chain and the toothed splint. At this time, the peanuts are continuously fed and move axially along the feeding drums 2, ensuring uniform force, high threshing efficiency, and accurate peeling of the pods by forward impact, reducing missed picking; When the harvested fruits are trailing peanuts (the stems and vines are prostrate and intertwined with each other) or long-stemmed whisker peanuts (the fruit stalks are long), the feeding drums 2 are adjusted to a vertical state for operation. At this time, the axis of the feeding drums 2 is perpendicular to the advancing direction of the harvesting body 1. The specific adjustment steps are as follows: The third driving motor 68 starts and drives the lead screw 67 to rotate. The lead screw 67 drives the displacement brackets 63 on both sides to slide on the first mounting bracket 61 towards both sides. At this time, the engagement between the first driving gear 65 and the transmission gear 52 is cancelled, and the rotating bracket 31 can rotate normally without interference with the first driving gear 65. The second electric push rod 71 remains in the holding state, the lifting bracket 72 is in the lower position, and the rotating bracket 31 will not interfere with the second driving gear 75; The first drive motor 9 starts and drives the multiple fixed shafts 10 to rotate through the belt transmission. At this time, the material distribution roller 2 is in a vertical state and there is a certain distance between each other. Then the second electric push rod 71 starts and drives the lifting bracket 72 to rise. Through this adjustment, the engagement of the driving gear 2 75 and the transmission gear 52 can be achieved. Finally, the fourth drive motor 73 starts and drives the multiple installation shafts 74 to rotate through the belt transmission. The installation shaft 74 drives the driving gear 2 75 to rotate, and the driving gear 2 75 drives the transmission gear 52 to rotate. The transmission gear 52 drives the output gear 51 and the material distribution roller 2 to rotate; The peanuts are conveyed by chains and toothed plates. When they are delivered to the dividing drum 2, the dividing drums 2 on both sides rotate in opposite directions and both face the peanuts. The impact force of the dividing drum 2 during rotation can separate the stems and pods. The separated pods enter the receiving plate at the bottom, while the stems are continuously conveyed backward along with the chains and toothed plates. At this time, the upper and lower parts of the long-stem peanuts are within the impact range of the dividing drum 2, ensuring that the small number of short-stem peanuts remaining on them are also separated at the same time. At this time, the peanuts are fed into the dividing drum 2. This rotation can effectively loosen the stems and reduce blockages.

[0025] Example 2: Please refer to Figure 10 , the present invention provides a technical solution: Different from the first embodiment, the rotating bracket 31 is provided with a protective cover plate 11, which is composed of a linear bent plate body and an arc-shaped bent plate body at one end. The protective cover plate 11 can isolate the high-speed rotating roller, gears and other moving parts, reduce the risk of the operator's hands or clothes being involved, and form a protective work for each gear structure to prevent peanuts from falling on the gear meshing position, which is conducive to ensuring the normal harvest of peanut fruits. At the same time, it reduces the mechanical failure rate, prevents peanut pods, stems and leaves from mistakenly entering the non-working area such as the transmission chain and bearings, reduces jamming and shutdown, and can prevent hard impurities (stones, metal fragments) from entering the gear meshing area, reducing the probability of pitting on the tooth surface; An opening position is provided on the linear bending plate, and the opening position is close to the positions of the driving gear 1 65 and the driving gear 2 75, so as to ensure the normal rotation switching of the rotating bracket 31, and at the same time, it can form an effective protection for the driving gear 2 75 in the vertical state.

[0026] Example 3: Please refer to Figures 11 - 12 , the present invention provides a technical solution: Different from Embodiment 1, guide tooth blocks 12 are provided on each of the plurality of first drive gears 65 and second drive gears 75. The guide tooth blocks 12 are designed as inclined surfaces or arc-shaped structures, which actively guide the teeth into the correct meshing position at the initial stage of gear contact, reduce the tooth surface impact caused by misalignment, and reduce the vibration amplitude of the shafting by evenly distributing the meshing force. In the solution, guide tooth blocks 12 are provided on both sides of the first drive gear 65 and the second drive gear 75, so as to ensure the quick connection when the first drive gear 65 or the second drive gear 75 meshes with the transmission gear 52.
