[0002] Seedling transplanting is the careful cultivation of seedlings or seeds and transplanting them to designated land at a certain time. Seedling transplanting is a labor-intensive, time-consuming and highly technical job.

[0003] Existing seedling transplanting methods are mostly manual. The work required for manual seedling transplanting is: first dig trenches in the land, then place the seedlings in the trenches, and finally cover the trenches with soil to achieve soil cultivation. This process is labor-intensive and technical.

[0004] There are also transplanting mechanical equipment on the market, some of which can only dig trenches, and some can only place seedlings in trenches after digging them, and the use effect is not good. Although the transplanting equipment that only digs trenches reduces the labor intensity of digging trenches and reduces the technical requirements for digging trenches, the subsequent workload is still large.

[0038] The pepper interplanting machine for wheat and pepper in this embodiment is used for interplanting pepper seedlings in wheat.

[0039] The technology involved in this embodiment is for hinge, and hinge is an existing mature connection method, which is implemented as follows: one of the two hinged objects is defined as A, and the other is defined as B.

[0040] The vehicle body 1 is a prior art vehicle, and an existing fuel agricultural vehicle can be directly selected. A power shaft is provided on the vehicle body 1, and the fuel added into the vehicle body 1 can drive the rotation of the power shaft, and the vehicle body 1 is driven forward by the rotation of the power shaft; a pulley 37 is installed on the power shaft, and the other parts of the pepper-interplanting transplanter are driven by the pulley 37.

[0041] The transmission part is connected to the support frame 7 , and the transmission part includes a main transmission shaft 28 , a final transmission shaft 29 and a power assembly; the power assembly drives the main transmission shaft 28 to rotate, and the main transmission shaft 28 is connected to the final transmission shaft 29 in terms of transmission.

[0042] The power assembly includes a hydraulic pump 40, a hydraulic motor 4, a transmission shaft, a main transmission shaft 28 and a final transmission shaft 29. A pulley 37 is provided on the vehicle body 1; an input shaft is provided on the hydraulic pump 40, and the pulley 37 is connected to the input shaft of the hydraulic pump 40 through a belt 38, thereby driving the hydraulic pump 40 to work.

[0043] The hydraulic pump 40 is connected to the hydraulic motor 4 through the oil pipe 5, so that the hydraulic pump 40 transmits hydraulic energy to the hydraulic motor 4, so that the hydraulic motor 4 can drive the subsequent components to work. In this embodiment, the hydraulic pump 40 and the hydraulic motor 4 are selected as part of the power assembly. The reason is that the hydraulic pump 40 and the hydraulic motor 4 work together to make the rotation speed of the main transmission shaft 28 stable, neither too fast nor too low, which is suitable for the present pepper interplanting transplanter, and at the same time, the cost is low, and the original power shaft on the vehicle body 1 is utilized.

[0044] Of course, as an alternative to this embodiment, the power assembly can also directly use a motor, and a battery is set on the support frame 7, and the battery provides power for the motor. The output shaft 121 of the motor is connected to the transmission shaft. However, the cost of this alternative embodiment is relatively high.

[0045] The transmission shaft is rotatably arranged on the support frame 7, the transmission shaft 29 is arranged along the width direction of the support frame 7, a sprocket wheel is mounted on the transmission shaft, and the output shaft 121 of the hydraulic motor 4 is connected to the sprocket wheel through the chain 6. Since the sprocket wheel is assembled on the transmission shaft, the transmission shaft rotates under the action of the hydraulic motor 4.

[0046] The main transmission shaft 28 is arranged at the rear of the transmission shaft, and the main transmission shaft 28 is rotatably arranged on the support frame 7. A sprocket wheel is assembled on the main transmission shaft 28, and the transmission shaft is connected to the sprocket wheel on the main transmission shaft 28 through the chain 6 transmission, so that the transmission shaft transmits power to the main transmission shaft 28.

[0047] The final transmission shaft 29 is arranged behind the main transmission shaft 28, and the final transmission shaft 29 is rotatably arranged on the support frame 7. A right angle commutator 12 is assembled on the final transmission shaft 29, and a driving gear is connected to the output shaft 121 of the right angle commutator 12.

[0048] The specific connection method of the support frame 7 and the vehicle body 1 is: it is well known that a lifting suspension assembly is provided on the vehicle body 1 of the agricultural vehicle, and the support frame 7 can be connected to the lifting suspension assembly of the vehicle body 1. For the existing lifting suspension assembly, it is composed of: an upper rotating rod and a lower rod located below the rotating rod, and the lower rod is fixedly arranged on the vehicle body 1. The rotating rod can rotate in the vertical direction, and the power of the rotation is provided by the power of the vehicle body 1. The specific implementation method is: a motor is provided on the vehicle body 1, and the power of the vehicle body 1 is provided to the motor to rotate the motor, and the motor drives the rotating rod to rotate. The rotating rod and its implementation method are mature existing technologies, such as the rotating rod installed at the rear of a small four-wheeler, which is used to realize the installation of agricultural equipment.

[0049] The support frame 7 is connected to the rotating rod in the following manner: the support frame 7 is provided with a suspension connecting rod 3, a support rod 302 and an auxiliary rod 2, the suspension connecting rod 3 is hinged with the rotating rod, and the hinge is realized in the following manner: a long hole 301 is provided on the suspension connecting rod 3, the long hole 301 is provided along the length direction of the suspension connecting rod 3, a hinge rod is slidably provided in the long hole 301, and the hinge rod is fixedly connected to the upper rotating rod. The rotating rod drives the suspension connecting rod 3 to rise and fall, and at the same time, the hinge rod can slide a certain distance in the long hole 301, so as to adapt to uneven roads during work and ensure the planting effect.

[0050] The support rod 302 is tilted, one end of the support rod 302 is connected to the support frame 7 , and the other end of the support rod 302 is fixedly connected to the suspension connecting rod 3 .

[0051] The auxiliary rod 2 is hinged to the lower rod, and the auxiliary rod 2 can achieve stability during the movement of the support frame 7.

[0052] Two planting parts are provided on the support frame 7 , and a gap is reserved between the two planting parts, and the gap can be used to bridge the wheat ridges. The two planting parts are both connected to the support frame 7 , and the two planting parts are symmetrically distributed along the width direction of the support frame 7 .

[0053] Since the pepper seedlings are interplanted on the wheat field in the present embodiment, the two planting sections plant the pepper seedlings on both sides of a ridge of wheat respectively.

[0054] The two planting parts have the same structure, and this embodiment only takes one of them as an example for explanation:.

[0055] The planting part includes a front wheel group, a plow group, a lifting component, a front and rear moving component, a seedling lowering component and a rear wheel group from front to back.

[0056] Among them, each planting part has two lifting components, two front and rear moving components, two rear wheel groups and two seedling lowering components. The lifting components, front and rear moving components, rear wheel groups and seedling lowering components are arranged in coordination to realize transplanting and planting.

[0057] The two lifting assemblies are respectively distributed along the width direction of the support frame 7, and each lifting assembly and the front-rear moving assembly respectively controls a seedling lowering assembly.

[0058] The two lower seedling assemblies are also distributed along the width direction of the support frame 7, the two front wheel groups are distributed along the width direction of the support frame 7, and the two rear wheel groups are distributed along the width direction of the support frame 7. The two front and rear moving assemblies are also distributed along the width direction of the support frame 7.

[0059] The front wheel group includes two front ground wheels 15, which are respectively arranged at the front lower part of the support frame 7. The front ground wheels 15 are in contact with the ground to reduce the resistance of the support frame 7 when it moves on the ground.

[0060] The coulter group comprises two coulters 16, and one planting part contains two coulters, so that two furrows can be dug on both sides of a row of wheat to realize the planting of pepper seedlings.

[0061] Two plowshares 16 are fixedly arranged at the bottom of the support frame 7, and the two plowshares 16 are located at the rear of both sides of the front ground wheel 15. The plowshares 16 can plow furrows on the ground, thereby realizing the placement of the pepper seedlings.

[0062] The rear wheel group includes two rear ground wheels 21 , which are respectively arranged at the rear lower part of the support frame 7 , and the two rear ground wheels 21 are arranged in cooperation with the plow 16 , specifically: the plow 16 is located on the symmetric line of the center line of the two rear ground wheels 21 .

[0063] A rear wheel set is matched with a coulter.

[0064] As for the structure of the rear ground wheels 21: the sides opposite to each other and the sides adjacent to each other of the two rear ground wheels 21 are both circular and concentric; at the same time, the sides opposite to each other of the two rear ground wheels 21 are smaller in diameter than the circular sides adjacent to each other of the two rear ground wheels 21; and the sides opposite to each other of the two rear ground wheels 21 and the sides adjacent to each other of the two rear ground wheels 21 are connected by an arc surface. Since the two diameters are different, the smaller the arc surface, the more the inner side is inclined upward. Through this structure, the soil can be squeezed inward, so that the pepper seedlings can be placed in the gully and the soil can be raised.

[0065] The seedling lowering assembly includes a material receiving cup 20 , an opening and closing unit, and a seedling lowering unit located above the material receiving cup 20 .

[0066] Seats 13 are provided at the front and rear of the seedling lowering assembly, and the user can sit on the seats 13 to put the seedlings into the seedling lowering unit. Guard plates 8 are provided on both sides of the front seat 13 to prevent people from hitting the transmission parts such as the chain 6, and to prevent foreign debris from being involved in the lifting assembly, the front and rear assemblies and the chain 6.

[0067] The material receiving cup 20 includes a frame 34 and two material receiving bodies 201 with arc-shaped cross-sections; the top of one of the two material receiving bodies 201 is hinged to the frame 34, and at the same time, the two material receiving bodies are connected through the frame 34 to form a material receiving cup with a circular cross-section; the opening and closing unit drives the material receiving body to rotate relative to the frame 34; elastic ropes 35 are arranged on the outside of the two material receiving bodies 201, so that after the bottom ends of the two material receiving bodies 201 are opened, they are reset under the action of the elastic ropes 35.

[0068] In order to reduce the influence of external factors on the seedlings, a seedling gathering tube 9 is inserted on the frame 34, and a receiving cup 20 is arranged below the seedling gathering tube 9. When working, the fallen pepper seedlings pass through the seedling gathering tube 9 and fall into the receiving cup 20, thereby preventing the wind from blowing the pepper seedlings and ensuring that the pepper seedlings keep their roots facing downward during the falling process.

[0069] The opening and closing unit can control the material receiving cup 20 to open or open, so that when the bottom end of the material receiving cup 20 is opened, the pepper seedlings are thrown onto the ground. The seedling lowering unit can realize the delivery of the pepper seedlings into the material receiving cup 20.

[0070] The opening and closing unit includes a pulling frame 27 , a drawing wire, a return spring 24 , a rotating wheel 22 , a first fixing frame, a second fixing frame, an opening and closing spring 35 and two opening and closing plates 34 .

[0071] The wire drawing includes a soft sleeve 25 and a soft inner wire 23 sleeved inside the soft sleeve 25; the soft inner wire 23 is fixedly arranged on a pulling frame 27, and the front end of the pulling frame 27 is hinged on the support frame 7; the middle part of the pulling frame 27 is connected to the bottom end of the reset spring 24, and the top end of the reset spring 24 is fixedly arranged on the support frame 7; the rotating wheel 22 is located behind the pulling frame 27, and the rotating wheel 22 is rotatably arranged on the support frame 7; the soft inner wire 23 is wound on the rotating wheel 22.

[0072] The front end of the soft sleeve 25 is connected to the support frame 7 .

[0073] The ends of the soft inner thread 23 and the soft sleeve 2 are respectively connected to the two material connection bodies 201 , ensuring that the material connection body connected to the soft inner thread 23 is in a hinged state with the frame 34 .

[0074] When working, the pulling frame 27 moves downward under the action of the power component to overcome the pulling force of the return spring 24, the soft inner wire 23 is pulled toward the front of the vehicle body 1, and the top of the material receiving body 201 hinged to the frame 34 overcomes the elastic force of the elastic rope 35 under the action of the soft drawing wire 23 and moves away from each other to open the material receiving cup 20.

[0075] When the force exerted by the power component on the pulling frame 27 is cancelled, the pulling frame 27 moves upward under the action of the return spring 24, and the soft inner wire 23 is pulled toward the rear of the vehicle body 1. At the same time, the top ends of the two receiving bodies 201 approach each other under the elastic force of the elastic rope 35, so that the receiving cup 20 is closed.

[0076] The lower seedling unit includes a lower seedling tube 10, and there are at least two lower seedling tubes 10. In this embodiment, there are five lower seedling tubes. The lower seedling tube 5 is connected to the transmission medium, and the transmission part drives the lower seedling tube 5 to transmit in the horizontal direction through the transmission medium. Among them, the transmission medium includes a transmission chain 11, and a driving gear 39 and a driven gear 10 are arranged on the support frame 7. The driving gear 39 is connected to the transmission part; the driving gear 39 and the driven gear 10 are both meshed with the transmission chain. The right-angle commutator 12 drives the transmission chain 11 to rotate in the horizontal direction relative to the support frame 7.

[0077] The specific implementation method is as follows: a vertically arranged output shaft 121 is mounted on the right-angle commutator 12 on the final transmission shaft 28, a driving gear 39 meshing with the transmission chain 11 is mounted on the top of the output shaft 121, a driven gear 10 rotatably arranged on a support frame is arranged in front of the driving gear 39, and the driven gear 10 and the driving gear support the transmission chain, so that under the action of the right-angle commutator 12, the driving gear 39 rotates, thereby driving the transmission chain 11 to transmit in the horizontal direction, driving the driven gear 10 to rotate, and the driven gear 10 can play a supporting role, and finally the lower seedling tube 10 is transmitted in the horizontal direction.

[0078] In order to adjust the tightness of the transmission chain, an adjustment frame is provided on the support frame 7, and the driven gear 10 is provided on the adjustment frame. The adjustment frame can be moved forward and backward on the support frame and then fixed, and the specific implementation method is: a horizontally arranged adjustment bolt 71 is fixed on the support frame 7, and two nuts 72 are screwed on the adjustment bolt 71, and the adjustment frame is fixed between the two nuts 72, so that the position of the adjustment frame 73 on the adjustment bolt 71 can be adjusted as needed, and the adjustment frame 73 is fixed after moving in the horizontal direction.

[0079] When the transmission chain 11 is loose, the position of the nut 72 is adjusted to move the adjustment frame forward, thereby tightening the transmission chain. When the transmission chain is too tight, the position of the nut 72 is adjusted to move the adjustment frame backward, thereby loosening the transmission chain.

[0080] When working, the transmission shaft drives the main transmission shaft 28 to rotate, and the main transmission shaft 28 drives the final transmission shaft 29 to rotate. As the final transmission shaft 29 rotates, the right-angle commutator 12 changes the transmission direction, and the right-angle commutator 12 drives the lower seedling tube 10 to transmit in the horizontal direction through the transmission chain 11.

[0081] The specific structure of the lower seedling tube is as follows: the lower seedling tube 10 includes two hinged lower seedling bodies 101, the cross-sections of the two lower seedling bodies 101 are both arc-shaped and bulge outwards, and the two lower seedling bodies 101 cooperate with each other to form the lower seedling tube 10; the lower seedling tube is arranged corresponding to the material receiving cup.

[0082] The two lower seedling bodies 101 include a first lower seedling body and a second lower seedling body. The first lower seedling body is fixedly connected to the transmission chain 11. The connection method is as follows: a bolt 111 is provided on the first lower seedling body, and the connection with the transmission chain 11 is achieved by the bolt 111 and a nut. The second lower seedling body is hinged to the first lower seedling body. A reset spring 103 is connected between the first lower seedling body and the second lower seedling body.

[0083] A horizontally arranged clamping rod 102 is arranged on the second lower seedling body, and a clamping block is arranged on the support frame to match the clamping rod 102. When the lower seedling tube rotates in the horizontal direction under the action of the transmission chain, when the clamping rod 102 hits the clamping block, the second lower seedling body is stuck, and an angle is formed between the first lower seedling body and the second lower seedling body, so that a hole appears at the bottom of the lower seedling tube, and the pepper seedling can drop from the lower seedling tube through the hole and enter the receiving cup.

[0084] As the angle between the first lower seedling body and the second lower seedling body becomes larger and larger, when the clamping rod 102 is perpendicular to the clamping block, the two are separated, and the first lower seedling body and the second lower seedling body are reset under the action of the reset spring 103, so that the bottom of the lower seedling tube is closed again.

[0085] In order to reduce the wear of the clamping rod 102 and the clamping block, the surfaces where the clamping rod 102 and the clamping rod 102 meet are both arc-shaped.

[0086] The lifting assembly is used to realize the lifting of the receiving cup 20. The lifting assembly includes a lifting wheel 26 and a connecting rod 19. The receiving cup 20 is connected to the end of the connecting rod 19. The connection method of the two is a fixed connection, which is welding in this embodiment.

[0087] The connecting rod 19 includes four rod bodies 181 , which are connected end to end to form a rectangle, and the joints of the four rod bodies 181 are hinged.

[0088] The lifting wheel 26 includes an inner wheel 261 assembled on the main transmission shaft 28, and an outer wheel 262 concentric with the inner wheel 261 is arranged outside the inner wheel 261. The minimum distance between the outer wheel 262 and the pulling frame 27 is less than zero, so that the power component acts on the pulling frame 27 in the following way: the lifting wheel 26 rotates, and when the outer wheel 262 rotates to the end of the pulling frame 27, the outer wheel 262 hits the pulling frame 27, pushing the pulling frame 27 downward until the inner wheel 261 of the lifting wheel 26 rotates to the pulling frame 27. Since the minimum distance between the pulling frame 27 and the inner wheel 261 is greater than zero, the pulling frame 27 will not contact the inner wheel 261, the contact between the pulling frame 27 and the lifting wheel 26 disappears, and the pulling frame 27 is reset.

[0089] A notch 901 is provided on the outer center wheel 262 , and the central angle of the notch 901 is larger than the central angle of the outer center wheel 262 ; a vertically arranged lifting rod 18 is provided on the inner center wheel 261 away from the outer center wheel 262 , and the bottom end of the lifting rod 18 is hinged on the connecting rod 19 .

[0090] The lifting rod 18 includes a rod body 181 and a sliding sleeve 182 slidably sleeved on the lower part of the rod body 181. A buffer spring located on the rod body 181 is provided above the sliding sleeve 182, and the bottom of the sliding sleeve 182 is connected to the connecting rod 19. By setting the lifting rod 18 in the form of the rod body 181 and the sliding sleeve 182, the pepper transplanter can be used on uneven ground, and when it encounters hard objects on the ground, it can automatically adjust the length and have a certain buffering effect.

[0091] The forward and backward moving assembly can drive the receiving cup 20 to move backward, thereby adapting to the forward displacement of the vehicle body 1, ensuring that the receiving cup 20 is stationary when in contact with the ground, preventing the receiving cup 20 from being pulled on the ground, and thus ensuring the transplanting effect.

[0092] The forward and backward moving assembly includes an eccentric bearing 30, a Z-shaped rod 32 and a connecting frame 33. The eccentric bearing 30 is assembled on the main transmission shaft 28; a vertically arranged connecting rod 31 is connected to the eccentric bearing 30, the end of the connecting rod 31 is hinged to the Z-shaped rod 32, and the end of the Z-shaped rod 32 is hinged to the connecting frame 33, wherein the connecting frame 33 and the Z-shaped rod 32 are both hinged to the support frame 7; the connecting frame 33 is hinged to the connecting rod 19.

[0093] As the main transmission shaft 28 rotates, the eccentric bearing 30 also rotates, causing the connecting rod 31 to move forward and backward. The connecting rod 31 drives the connecting rod 19 to move forward and backward under the action of the Z-shaped rod 32 and the connecting frame 33, and finally drives the receiving cup 20 to move forward and backward, so that the receiving cup 20 is stationary when in contact with the ground.

[0094] In this embodiment, four rows of peppers can be planted, and each planting part can plant two rows. Each planting part has two coulters, two rear wheel groups, two receiving cups, two lifting components, two opening and closing units, and two front and rear moving components.

[0095] One lifting component and one forward and backward moving component control the lifting and backward movement of a receiving cup, and each opening and closing unit controls the opening and closing of a receiving cup.

[0096] A plow digs a furrow, a lifting component controls the receiving cup to rise, and then lowers after receiving the seedlings, a forward and backward moving component controls the receiving cup to remain still on the ground, and an opening and closing unit controls the receiving cup to open, so that the seedlings fall to the ground, and then a rear wheel group realizes the soiling of the pepper seedlings in the furrow.

[0097] The working process is as follows: a person sits on the seat 13 and throws seedlings into the lower seedling tube; the transmission chain 11 drives the lower seedling tube to rotate, and when the lower seedling tube corresponds to the receiving cup, the clamping rod contacts the clamping block, thereby separating the first lower seedling body and the second lower seedling body, and the seedlings in the lower seedling tube enter the receiving cup 20.

[0098] The transmission shaft drives the main transmission shaft 28 to rotate under the transmission of the chain 6. As the main transmission shaft 28 rotates, the eccentric bearing 30 rotates, causing the connecting rod 31 to move forward and backward while rising and falling; while the main transmission shaft 28 rotates, the lifting wheel 26 rotates. During the rotation of the lifting wheel 26: when the pulling frame 27 is pushed downward and the wire drawing is performed, the lifting rod 18 drives the receiving cup 20 with the seedlings to move to the lowest point. At the same time, the connecting rod 31 drives the receiving cup 20 to remain stationary at the lowest point. The wire drawing is performed to open the bottom end of the receiving cup 20, and the seedlings in the receiving cup 20 come out of the receiving cup 20.

[0099] The rear ground wheel group 21 squeezes the soil toward the seedlings to achieve soil cultivation.

[0100] Subsequently, the opening and closing spring 35 closes the receiving cup 20, and the lifting rod 18 drives the receiving cup 20 to move upward, ready to receive new seedlings.

[0101] Repeat the process until all the seedlings are planted.

[0102] The pepper-interplanting transplanter of the present invention can realize mechanical planting of transplanting, reduce the labor intensity of users, and improve the work efficiency of transplanting. In addition, the pepper-interplanting transplanter of the present invention has low cost, novel and ingenious design, and each component cooperates with each other to improve the transplanting effect, thereby improving the survival rate during the transplanting process. In addition, the pepper-interplanting transplanter of the present invention has a wide range of uses, and the number of planting parts can be selected according to needs, thereby planting different seedlings.

[0103] The present invention also discloses a pepper transplanting method using the above-mentioned pepper-wheat interplanting transplanter, the method comprising the following steps in sequence:

[0104] 1) Place the seedlings in the lower seedling tube, and the transmission chain drives the lower seedling tube to move horizontally. When the lower seedling tube rotates to the second lower seedling opening of the tray, the receiving cup just rises;

[0105] 2) The seedlings fall from the lower seedling tube into the receiving cup;

[0106] 3) The receiving cup descends, and the transmission chain drives the lower seedling tube to move;

[0107] 4) When the receiving cup is descending, as the vehicle body moves forward, the receiving cup moves backward, and the moving speed is equal to the forward speed of the vehicle body, thereby avoiding the phenomenon that the receiving cup is dragged on the ground during the movement of the vehicle body.

[0108] 5) When the receiving cup drops to the lowest point, the bottom of the receiving cup opens, and the seedlings come out of the receiving cup and fall onto the ground.

[0109] When working, when one of the two receiving cups on the same receiving tray of the same planting section receives the seedlings, the other receiving cup is at the lowest point, thus ensuring that the two rows of seedlings are planted in staggered rows, ensuring that each seedling receives sufficient sunlight, thereby maintaining the growth of the seedlings.

[0110] The lifting wheel drives the lifting rod to move up and down as the main transmission shaft rotates, and the lifting rod drives the receiving cup to move up and down under the action of the connecting rod; the eccentric bearing rotates as the main transmission shaft rotates, thereby driving the connecting rod to move up and down while moving forward and backward.

[0111] The connecting rod drives the receiving cup to move forward and backward.

[0112] The method described in the present invention can realize transplanting and planting, and at the same time, the two rows of pepper seedlings are planted in staggered rows, which ensures the reception of sunlight and thus improves the subsequent growth ability of the pepper seedlings; in addition, when planting peppers, the material receiving cup will remain relatively still with the ground when it is at the lowest point, thereby avoiding the situation where the material receiving cup is pulled on the ground during the planting process.
