Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an automatic unloading device for a peanut harvesting and picking machine. Background Art

[0002] Newly harvested peanuts have a moisture content of about 50% for mature pods and about 60% for immature pods. If not dried in time, they are prone to mildew, deterioration or frost damage. In order to store them safely and ensure the quality of the peanuts, they must be dried in time after harvest.

[0003] After the peanuts are harvested, the peanut harvesting and picking machine in the prior art usually throws the peanuts directly into the field, allowing the peanuts to stay in the field for ventilation and drying. Since the peanut seedlings are long and the peanut fruits are heavy, after the peanuts are thrown directly into the field, part of the peanut fruits are still in contact with the field soil, resulting in reduced peanut fruit drying efficiency. In addition, when the seedlings are blown by the wind, the seedlings are very likely to cover the fruits, resulting in further reduced ventilation and drying efficiency of the fruits.

[0022] like Figure 2-Figure 4 As shown, the diffusion mechanism also includes a first air pump 301, and the first air pump 301 is installed on one side of the frame 1, and pneumatic telescopic rods 302 are symmetrically fixedly connected up and down, and the output end of the first air pump 301 and the inner cavity of the pneumatic telescopic rod 302 are commonly connected by a first air supply pipe 3021. The first air pump 301 can control the movement of the telescopic ends of the two pneumatic telescopic rods 302 through the first air supply pipe 3021. The fixed ends of the two first elastic telescopic rods 201 are rotatably connected to the telescopic ends of the two pneumatic telescopic rods 302 respectively, and the outer wall of the fixed end of the first elastic telescopic rod 201 is movably sleeved with a sleeve 303, and the sleeve 303 is fixedly connected to the frame 1 through a support plate, and the inner wall of the sleeve 303 is provided with a wave groove 304, and the outer wall of the fixed end of the first elastic telescopic rod 201 is fixedly connected with a sliding shaft, and one end of the sliding shaft is stuck in the wave groove 304 and slides therein.

[0023] like Figure 5As shown, the restraining mechanism includes a telescopic shaft 401, and the telescopic shaft 401 is fixedly connected symmetrically to the inner rear side of the frame 1. The telescopic end of the telescopic shaft 401 is fixedly connected to an arc frame 402, and the arc frame 402 is located at the lower side of the first conveyor belt 101. The two arc frames 402 form a complete ring when combined.

[0024] like Figure 5 and Figure 6 As shown, the binding mechanism also includes a second elastic telescopic rod 501, the inner wall of the arc frame 402 is fixedly connected to the second elastic telescopic rod 501, and the outer wall of the telescopic end of the second elastic telescopic rod 501 is symmetrically hinged with a clamping rod 502, the two clamping rods 502 of one second elastic telescopic rod 501 are offset up and down from the two clamping rods 502 of the other second elastic telescopic rod 501, a first elastic member is arranged between the clamping rod 502 and the telescopic end of the second elastic telescopic rod 501, the first elastic member is a torsion spring, the inner wall of the arc frame 402 is symmetrically fixedly connected to a cross bar 503, one end of the cross bar 503 is rotatably connected to a roller used in conjunction with the clamping rod 502, when the telescopic end of the second elastic telescopic rod 501 contracts, the roller of the cross bar 503 can squeeze the outer wall of the clamping rod 502, so that the clamping rod 502 rotates with the connection point of the telescopic end of the second elastic telescopic rod 501 as the center of the circle.

[0025] Initially, the two first elastic telescopic rods 201 are in a released state, and the telescopic ends of the two pneumatic telescopic rods 302 are in a contracted state, and the first conveyor belt 101 and the second conveyor belt 102 are started, and the first conveyor belt 101 and the second conveyor belt 102 convey the peanuts, and the peanut fruits are located on the upper side of the first conveyor belt 101, and the peanut seedlings are clamped and conveyed by the first conveyor belt 101 and the second conveyor belt 102, and then the second conveyor belt 102 is no longer in contact with the peanut seedlings, and the first conveyor belt 101 continues to convey the peanuts, and the first air pump 301 is started, and the first air pump 301 controls the extension of the telescopic ends of the two pneumatic telescopic rods 302 through the first air pipe 3021, so that the two first elastic telescopic rods 201 move closer to each other, and at the same time At the same time, the telescopic ends of the two telescopic shafts 401 extend, so that the two arc frames 402 move closer to each other, and the arc frame 402 drives the two clamping rods 502 to move through the second elastic telescopic rod 501 thereon. The telescopic ends of the two second elastic telescopic rods 501 respectively contact and squeeze the peanut seedlings, and the telescopic ends of the second elastic telescopic rods 501 shrink under force, and drive the two clamping rods 502 thereon to move, and the rollers on the cross bar 503 squeeze the outer walls of the adjacent clamping rods 502. The clamping rods 502 are forced to rotate with the connection point of the telescopic ends of the second elastic telescopic rods 501 as the center of the circle, and the first elastic member is forced to shrink. At this time, the four clamping rods 502 are respectively in contact and squeeze the peanut seedlings, and the squeezed parts of the peanut seedlings are more compact after being stressed, thereby preventing the peanut seedlings from subsequent dispersion. During the movement of the two first elastic telescopic rods 201, the sliding shaft of the first elastic telescopic rod 201 slides along the wave groove 304 of the corresponding sleeve 303, and drives the first elastic telescopic rod 201 to reciprocate with the connection point of the telescopic end of the pneumatic telescopic rod 302 as the center of the circle. The telescopic end of the first elastic telescopic rod 201 drives the corresponding six first connecting rods 203 to reciprocate through the disc 202, and the fixed end of the first elastic telescopic rod 201 drives the corresponding six second connecting rods 204 to reciprocate through the ring 206. Then, the two discs 202 are in contact with the peanut fruits or seedlings respectively. Under the action of the reciprocating rotation, the two discs 202 can produce a kneading effect on the peanut fruits or seedlings, so that the peanut fruits or seedlings are kneaded by the discs 202. The center of the circle initially spreads outward, and by allowing the peanut fruits or seedlings to initially spread, the peanut fruits or seedlings can be prevented from blocking the disc 202, so that the two discs 202 can move more smoothly. Since the peanut seedlings are squeezed by the four clamping rods 502 at this time, when the two discs 202 rub the peanut fruits or seedlings, the peanut seedlings will not rotate, thereby further improving the diffusion effect of the peanut fruits or seedlings. Subsequently, the two discs 202 are blocked by the peanut fruits or seedlings and cannot continue to move, thereby causing the telescopic ends of the two first elastic telescopic rods 201 to contract. It is worth noting that the elastic force of the first elastic telescopic rod 201 is relatively small, and the telescopic end of the first elastic telescopic rod 201 will not drive the disc 202 to damage the peanut fruits and seedlings.When the telescopic end of the first elastic telescopic rod 201 is retracted, the six first connecting rods 203 thereon rotate around the connection point of the disk 202 as the center of the circle under the action of the second connecting rod 204, and the two adjacent first connecting rods 203 jointly drive the soft cloth 205 to open. During the process of the soft cloth 205 opening, the two first elastic telescopic rods 201 are still reciprocating, thereby further improving the dispersion effect of the peanut fruits or seedlings through the soft cloth 205. When the telescopic ends of the two first elastic telescopic rods 201 are completely retracted, the soft cloth 205 forms a flat state under the action of the first connecting rod 203, and the soft cloth 205 can make the peanuts spread by contacting and squeezing the peanut seedlings. The first air pump 301 controls the telescopic ends of the two pneumatic telescopic rods 302 to contract through the first air pipe 3021, thereby causing the two first elastic telescopic rods 201 to move away from each other. During the process of the two first elastic telescopic rods 201 moving away from each other, the telescopic ends of the two first elastic telescopic rods 201 are gradually released, thereby causing the six adjacent first connecting rods 203 to rotate and reset. The sliding shafts of the first elastic telescopic rods 201, under the action of the wave groove 304, cause the six first connecting rods 203 to continue to reciprocate. At this time, the peanut fruits or seedlings are squeezed and the first connecting rods 203 are pressed together. During the reciprocating rotation, the distance between the first connecting rod 203 and the peanut fruit or seedling increases, and the first connecting rod 203 will not affect the peanut fruit or seedling until the telescopic ends of the two first elastic telescopic rods 201 are completely released, and the six adjacent first connecting rods 203 rotate and reset under the action of the second connecting rod 204 until the telescopic end of the pneumatic telescopic rod 302 is reset. At the same time, the telescopic ends of the two telescopic shafts 401 respectively drive the two arc frames 402 to move away from each other. During the movement of the arc frame 402, the telescopic end of the second elastic telescopic rod 501 is gradually released, and drives the two clamping rods 502 thereon to move. The first elastic member is released to make The clamping rod 502 rotates and resets until the telescopic ends of the two telescopic shafts 401 are completely reset, and the first conveyor belt 101 continues to transport the peanuts, and the peanuts are placed in the field through the unloading mechanism in the prior art. Since the peanut fruits and seedlings are squeezed, when the peanuts are placed in the field, the peanut seedlings are in contact with the soil and provide support for the peanut fruits. The peanut fruits and seedlings are in an I-shape, with the fruits located on the upper side, and the peanut fruits and seedlings are spread in a circular shape. When the peanut seedlings are blown by the wind, the peanut seedlings will not block the peanut fruits, thereby greatly increasing the contact area between the peanut fruits and the air and increasing the drying speed of the peanut fruits.

[0026] like Figure 7 , Fig. 9 and Fig.10As shown, a cleaning mechanism is also included, the cleaning mechanism includes a second air pump 601, the second air pump 601 is installed on the rear side of the top of the frame 1, and is fixedly connected to a second air pipe 602, one end of the second air pipe 602 is connected to the output end of the second air pump 601, the inner wall of the second air pipe 602 is symmetrically connected to an impeller 603, the rotating shaft of the impeller 603 rotates through the second air pipe 602 and is fixedly connected to a rotating disk 604, one end of the rotating disk 604 is fixedly connected to six evenly distributed A toggle plate 605 is arranged on one side of the rotating disk 604, and a gravity block 606 is fixedly connected to one side of the gravity block 606 with a convex shaft used in conjunction with the six toggle plates 605. When the rotating disk 604 rotates, the six toggle plates 605 thereon can be driven to squeeze the convex shaft of the gravity block 606, so that the convex shaft drives the gravity block 606 to lift upwards. The other end of the second air supply pipe 602 is connected to a special-shaped pipe 607, and the outer wall of the special-shaped pipe 607 is provided with a plurality of evenly distributed air outlet holes.

[0027] like Figure 7 , Fig. 9 and Fig.10 As shown, the cleaning mechanism also includes a connecting frame 701, which is fixedly connected to the frame 1, and the connecting frame 701 is slidably connected to the gravity block 606 in a through-type manner. Two groups of rotating rods 702 are rotatably connected on both sides of the connecting frame 701, and each group consists of two. A second elastic member is arranged between the rotating rod 702 and the connecting frame 701, and the second elastic member is a torsion spring. The top of the rotating rod 702 is rotatably connected to a rolling wheel, and the rolling wheel is used in conjunction with the gravity block 606. A sliding groove is provided at the bottom of the rotating rod 702, and a sliding rod 703 is horizontally slidably connected in the sliding groove. A third elastic member is arranged between the sliding rod 703 and the inner wall of the sliding groove, and the third elastic member is a compression spring. One end of the sliding rod 703 is fixedly connected to a wave plate 704.

[0028] like Fig. 9 and Fig.10 As shown, the cleaning mechanism also includes a T-shaped plate 801, the T-shaped plate 801 is symmetrically fixed to the bottom of the connecting frame 701, and the inclined rods 802 are symmetrically fixed to the two sides of the T-shaped plate 801. The sliding rod 703 is used in conjunction with the inclined rod 802. When the sliding rod 703 contacts the inclined rod 802, the sliding rod 703 can drive the wave plate 704 to move horizontally.

[0029] like Figure 7 and Figure 11-12As shown in the figure, it further includes a kneading mechanism. The kneading mechanism includes a driving motor 901. The driving motors 901 are symmetrically installed on the left and right in the middle of the frame 1. A cam 902 is fixedly connected to the output shaft of the driving motor 901. The U-shaped frames 903 are symmetrically and fixedly connected to the left and right in the middle of the frame 1. A sliding frame 904 is slidably connected to the top of the U-shaped frame 903. A rotating wheel cooperating with the cam 902 is rotatably connected in the sliding frame 904. A fourth elastic member is arranged between the sliding frame 904 and the inner wall of the U-shaped frame 903. The fourth elastic member is a compression spring. A third connecting rod 905 is hinged to the side of the sliding frame 904 away from the cam 902. One end of the third connecting rod 905 is hinged to a kneading plate 906. Fifth elastic members are respectively arranged between the third connecting rod 905 and the sliding frame 904 and the kneading plate 906. The fifth elastic members are torsion springs.

[0030] As Fig.12 shown in the figure, the kneading mechanism further includes an L-shaped plate 1001. The L-shaped plate 1001 is fixedly connected to the U-shaped frame 903. A limiting block 1002 is hinged to the bottom of the L-shaped plate 1001. A sixth elastic member is arranged between the limiting block 1002 and the L-shaped plate 1001. The sixth elastic member is a torsion spring. A protruding shaft cooperating with the limiting block 1002 is fixedly connected to one side of the kneading plate 906. The limiting block 1002 can limit the moving track of the kneading plate 906 through the protruding shaft.

[0031] As Fig.11 shown in the figure, it further includes a connecting rod 1101. The connecting rod 1101 is fixedly connected to one side of the sliding frame 904. A through groove is formed in the outer wall of the fixed end of the telescopic shaft 401. One end of the connecting rod 1101 is clamped into the through groove and slides therein, and is fixedly connected to the outer wall of the telescopic end of the telescopic shaft 401. When the sliding frame 904 moves, it can drive the telescopic end of the telescopic shaft 401 through the connecting rod 1101.

[0032] Initially, the second elastic member is in a released state, the inclined surface of the gravity block 606 contacts the rolling wheel of the corresponding rotating rod 702, and there is a large gap between the two adjacent wave plates 704. When the peanut harvesting and picking machine in the prior art transports the peanuts to the first conveyor belt 101 and the second conveyor belt 102, the first conveyor belt 101 and the second conveyor belt 102 are started, and the peanut seedlings clamped by the first conveyor belt 101 and the second conveyor belt 102 transport the peanuts. At this time, the peanut fruits face upward and are located on the upper side of the first conveyor belt 101. The second air pump 601 is started, and the second air pump 601 transports air to the second air pipe 602. The two impellers 603 rotate under the impact of the air, and drive the corresponding rotating disk 604 to rotate. The rotating disk 60 4 drives the six toggle plates 605 thereon to revolve. When one of the toggle plates 605 contacts the convex shaft of the adjacent weight block 606, the convex shaft is squeezed by the toggle plate 605 and slides upward along the connecting frame 701, so that the weight block 606 is away from the rolling wheel of the corresponding rotating rod 702. Then the toggle plate 605 passes over the convex shaft and no longer contacts the convex shaft. After the convex shaft is freed from the restriction, the weight block 606 can move. The weight block 606 falls downward rapidly under the influence of its own weight. Then the inclined surface of the weight block 606 hits the surface of the rolling wheel of the corresponding rotating rod 702. The rolling wheel is driven by the force to drive the rotating rod 702 to rotate rapidly downward with the connection point of the connecting frame 701 as the center of the circle. The second elastic member is forced to shrink, and the rotating rod 702 drives the wave plate 704 to move rapidly upward through the sliding rod 703. The two adjacent wave plates 704 quickly swing towards each other, and then the sides of the two adjacent wave plates 704 that are close to each other respectively contact and collide with the peanut fruit, so that the soil on the peanut fruit shell falls off. At the same time, the outer wall of the sliding rod 703 contacts the outer wall of the corresponding inclined rod 802, and slides along the slide groove of the corresponding rotating rod 702 under the action of the inclined rod 802. The third elastic member is forced to shrink. At this time, the two adjacent wave plates 704 slide horizontally in opposite directions. Under the action of the two adjacent wave plates 704, the peanut fruit shells generate friction with each other, thereby further improving the effect of soil falling off the peanut fruit shells, thereby further improving the drying speed of the peanuts. At the same time, the second air pipe 6 The air in 02 enters the special-shaped tube 607 and blows toward the peanut fruits and seedlings through several air outlets of the special-shaped tube 607, thereby blowing off the loose soil on the shell of the peanut fruit. Then, the second elastic member is released to drive the rotating rod 702 to rotate and reset. The rolling wheel of the rotating rod 702 squeezes the inclined surface of the gravity block 606, and the gravity block 606 is forced to lift upward and reset. The rotating rod 702 drives the corresponding wave plate 704 to swing and reset through the sliding rod 703. After the sliding rod 703 is reset, it no longer contacts the outer wall of the inclined rod 802. The third elastic member is released and drives the wave plate 704 to slide and reset through the sliding rod 703. At this time, the rotating disk 604 continues to rotate, so that the adjacent six toggle plates 605 are constantly in contact with the convex shafts of the corresponding gravity blocks 606.Repeat the above steps to achieve the same effect.

[0033] At the same time, the driving motor 901 is started, and the output shaft of the driving motor 901 drives the cam 902 to rotate. The cam 902 squeezes the rotating wheel of the adjacent sliding frame 904, and the rotating wheel is forced to drive the sliding frame 904 to slide horizontally. The fourth elastic member is forced to shrink, and the sliding frame 904 applies a thrust to the kneading plate 906 through the third connecting rod 905. At this time, the two kneading plates 906 move closer to each other, and the kneading plates 906 will not rotate under the action of the fifth elastic member. Subsequently, the sides of the two kneading plates 906 that are close to each other are respectively in contact with the peanut seedlings, and the sliding frame 904 continues to move, and continues to pass through the third connecting rod 905. The three-link 905 applies a thrust to the kneading plate 906, and the two kneading plates 906 are forced to move horizontally in opposite directions, and the fifth elastic member is forced to shrink, and the two kneading plates 906 squeeze and knead the peanut seedlings, and the peanut seedlings are forced to rotate, thereby changing the position of the peanut fruit. While the kneading plates 906 move horizontally, the kneading plates 906 drive the protruding shafts thereon to squeeze the outer walls of the adjacent limit blocks 1002, and the limit blocks 1002 are forced to rotate with the connection point of the L-shaped plate 1001 as the center of the circle, and the sixth elastic member is forced to shrink until the protruding shaft is no longer connected to the limit blocks 1002. The cam 902 no longer squeezes the rotating wheel of the adjacent sliding frame 904, and the fourth elastic member is gradually released to drive the sliding frame 904 to slide and reset. The sliding frame 904 drives the rotating wheel therein to move and reset, and applies a pulling force to the rubbing plate 906 through the third connecting rod 905, so that the two rubbing plates 906 move away from each other, and the protruding shaft on the rubbing plate 906 contacts the side wall of the limit block 1002, and the limit block 1002 does not rotate, and then the rubbing plate 906 is pulled by the protruding shaft. 06 limits the moving trajectory, so that the rubbing plate 906 moves horizontally, and the fifth elastic member remains in a contracted state to prevent the rubbing plate 906 from moving back and forth too quickly when resetting, causing the peanut seedlings to be rubbed again, reducing the effect of changing the position of the peanut seedlings. Through the above steps, the contact area between the peanut fruit shell and the wave plate 704 can be further increased, thereby increasing the effect of soil shedding. Subsequently, the protruding axis of the rubbing plate 906 passes over the adjacent limit block 1002 and no longer contacts the limit block 1002, the fifth elastic member is released, and the rubbing plate 906 is driven to reset through the third connecting rod 905.

[0034] When the sliding frame 904 slides, the sliding frame 904 drives the telescopic end of the telescopic shaft 401 to extend outward through the connecting rod 1101, thereby enabling the four clamping rods 502 to support the peanut seedlings and achieve the above-mentioned effect.
