Description

Technical Field

[0001] The invention relates to a potato planting device, in particular to an adjustable potato planting device and a method thereof. Background Art

[0002] Potatoes are what we often call potatoes. Although potatoes do not have to germinate before sowing, sowing sprouted potatoes can increase the success rate of planting. In order to ensure the survival rate of planting, traditional potato planting activities are carried out manually.

[0003] To meet the needs of large-scale planting, existing technology has also invented corresponding planting machinery, but the machinery can only control the planting density and the depth of soil covering, and there is no way to ensure the position of the buds during planting. At least a quarter of the planted potatoes may have the problem of buds being pressed and unable to grow. In addition, a large number of friction and collisions are inevitable during the mechanical planting process, which can easily damage the buds on the surface of the potatoes and affect the sowing survival rate.

[0004] To this end, those skilled in the art have proposed an adjustable potato planting device and method thereof to achieve mechanized potato planting with a high survival rate, ensure that the potato buds face upward, and prevent the buds from being severely damaged due to collisions. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an adjustable potato planting device and method thereof. The device utilizes the characteristics that sprouted potatoes gradually shrink and are not prone to rolling against each other, and a lever for conveying the sprouted potatoes is arranged in a material box, so that the potatoes are smoothly pushed to a material box outlet, and then the bulbs are sown in sequence at certain intervals through a sowing conveyor belt arranged at the material box outlet. During the entire sowing process, the potatoes will not rub or collide against each other too much, and the bulbs will not roll and damage the buds, so the bulbs with buds are sown smoothly in the planting ridges, thereby ensuring the planting success rate.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustable potato planting device, including a material box, the material box is used to store germinated potato bulbs, and the rear side of the material box is provided with discharge ports running through it in parallel, and multi-ridge synchronous sowing of potato bulbs is carried out through the discharge ports.

[0007] A sowing conveyor belt is arranged below the material box discharge port, and the potato bulbs discharged from the material box discharge port fall on the sowing conveyor belt. The bulbs are smoothly conveyed to the planting ridges through the operation of the sowing conveyor belt. The sowing conveyor belt can adjust the sowing depth to adapt to the planting ridges and control the sowing density.

[0008] A lever is provided on the inner side of the material box, through which the stacked and mutually adhered potato bulbs are separated, and pushed one by one to the material box discharge port for sequential discharge. The advance of the lever is controlled accordingly according to the conveying speed of the sowing conveyor belt to ensure that the lever acts on all materials in the material box and that the lever does not exert excessive pushing force on the potato bulbs to cause them to roll or excessive friction to damage the bud points on the bulbs.

[0009] Preferably, an extension rod is hingedly provided on the side of the material box and below the discharge port, a first gear is rotatably provided between the two extension rods, the sowing conveyor belt is meshed with the first gear and is arranged below the discharge port, and the rotation speed of the first gear is controlled by controlling the motor to achieve control of the sowing density, and the extension rods on both sides ensure that the bulbs will not roll off the sowing conveyor belt.

[0010] Furthermore, a triangular protective plate is fixedly installed under the sowing conveyor belt. The triangular protective plate can prevent the sowing conveyor belt from contacting the ground due to the ups and downs of the planting ridges and affect the movement of the equipment. It also has the function of leveling the sowing ground and ensuring the sowing depth.

[0011] Preferably, a protrusion is fixedly connected to the lower surface of the extension rod, and a control shaft is transversely penetrated through the side of the protrusion. The control shaft controls the extension rod through the rotation of the protrusion. Adjustment arms are fixedly connected to both ends of the control shaft. By adjusting the angle of the adjustment arm, all the extension rods on the side of the control shaft are controlled to rotate together. The rotating end of the extension rod is close to the ground in the planting ridge, ensuring that the potato bulbs will not roll during planting, thereby achieving smooth planting.

[0012] Preferably, a fixed block is fixedly connected to the side of the sowing conveyor belt, and a partition is hingedly provided on the side of the fixed block. A first spring is provided between the fixed block and the partition, and a blockage is formed at the discharge port of the corresponding material box through the partition. Only when the two partitions on the side of the sowing conveyor belt are respectively located on both sides of the discharge port can the material be discharged smoothly.

[0013] The partition plate hinged on the side of the fixed block is tightened by the first spring to ensure a vertical state, and can be rotated to avoid obstacles when encountering obstacles, which is conducive to saving equipment space.

[0014] Preferably, an advance rod is inserted into the side of the material box corresponding to the discharge port, and second gears are provided at both ends of the advance rod. A discharge track is provided on the side of the advance rod through the second gear meshing, and the shift rod is hinged on the side of the discharge track. The installation of the advance rod corresponding to the discharge port facilitates the sequential discharge of the bulbs pushed by the shift rod through the discharge port.

[0015] The advance rod drives the discharge crawler to circulate through the second gears at both ends. The drive is associated with the drive structure of the sowing conveyor belt and is positively correlated in a certain proportion. The movement of the advance rod into the material box is driven by another separate drive structure and requires additional control based on actual use.

[0016] Preferably, a baffle is fixedly connected to the outer side of the advancement rod corresponding to the shifting rod, and the bulb is restricted by the outer baffle when being pushed by the shifting rod and can only move along the baffle, thereby facilitating the control of the movement of the bulb to the discharge port.

[0017] A second spring is arranged between the discharging crawler and the lever, and a contact rubber pad is fixed on the side of the lever away from the second spring at an inverse angle. The contact rubber pad can not only ensure the contact friction between the lever and the bulb to ensure a good pushing effect, but also prevent the hard structure from contacting and damaging the bud points on the surface of the bulb.

[0018] The lever is hingedly arranged on the side of the discharging track through a second spring. When the lever moves to the inside of the baffle, it will not cause excessive force on the bulb. When the lever is obstructed by the bulb, the second spring is compressed and the lever is deflected, thereby ensuring the integrity of the bud points on the surface of the bulb.

[0019] Preferably, a slide groove is provided on the upper surface of the advancing rod along the advancing direction, a driving shaft is inserted into the inner side of the slide groove, the driving shaft is rotatably connected to the material box, and the advancing rod is driven by the driving shaft.

[0020] The driving shaft is driven to rotate by a power structure, and the rotating driving shaft drives the advancing rod to advance along the direction of the slide slot through meshing action, thereby ensuring that the lever can collect the bulbs at different depths in the material box.

[0021] Preferably, a third gear is sleeved on the side surface of the driving shaft, and a rack is fixedly provided on the inner wall of the sliding groove corresponding to the third gear. The driving shaft drives the advancement rod to advance through the meshing action of the third gear and the rack.

[0022] A clamping slider is rotatably sleeved on the side of the driving shaft and located outside the third gear. The clamping slider sleeved on the side bearing of the driving shaft ensures the clamping movement between the driving shaft and the inner wall of the slide groove, thereby ensuring the stability of the equipment advancement.

[0023] The side surface of the pressing slide block is pressed against the inner wall of the slide groove, and the roller is arranged to reduce the friction between the pressing slide block and the inner wall of the slide groove, so that the advancement of the advancement rod is more stable and smooth.

[0024] Preferably, a guide rod is also provided through the inner side of the slide groove, and the guide rod is fixedly connected to the inner wall of the material box. The guide rod cooperates with the driving shaft to position the two ends of the advance rod to ensure the stable advance direction of the advance rod.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The embodiment of the present invention discloses an adjustable potato planting device and method thereof;

[0048] According to the attached Figure 1 As shown, it includes a material box 1, and a plurality of discharge ports are arranged in parallel on the side wall of the material box 1. A sowing conveyor belt 2 is arranged below the discharge port of the material box 1, and a lever 3 is arranged on the inner side of the material box 1. The material in the material box 1 is transported to the discharge port in an orderly manner through the lever 3. The material falls onto the sowing conveyor belt 2 through the discharge port, and is smoothly transported to the ground through the sowing conveyor belt 2 for sowing. During the entire sowing process, there is less friction and collision between the materials, and the materials will not roll over, thereby ensuring that the buds on the surface of the planted potatoes are not damaged, thereby ensuring the survival rate.

[0049] According to the attached Figure 2 and attached Figure 3 As shown, an extension rod 4 is hingedly provided on the side of the material box 1 and below the discharge port, a first gear 5 is rotatably provided between the two extension rods 4, and the sowing conveyor belt 2 is meshed and arranged below the discharge port through the first gear 5. The installation angle of the sowing conveyor belt 2 on its side is adjusted by the hinged extension rod 4. The rotating end of the sowing conveyor belt 2 is extended by the extension rod 4 to stably convey the potato bulbs to the ground near the inner side of the planting ridge for planting, which can not only control the planting depth but also avoid the potato bulbs from rolling over and damaging the buds on the side due to the height difference as much as possible.

[0050] A triangular protective plate 6 is fixedly arranged under the sowing conveyor belt 2. During the rotation and adjustment of the extension rod 4, the triangular protective plate 6 is always on the rotating side of the extension rod 4 and touches the ground before the sowing conveyor belt 2, so as to prevent the uneven ground from affecting the operation of the sowing conveyor belt 2. At the same time, the triangular protective plate 6 can also level the planting ground to a certain extent, ensuring the planting depth of potatoes, thereby ensuring the planting survival rate.

[0051] A protrusion 7 is fixedly connected to the lower surface of the extension rod 4. A control shaft 8 is transversely penetrated through the side of the protrusion 7. The control shaft 8 rotates to control the extension rod 4 through the protrusion 7. Adjustment arms 9 are fixedly connected to both ends of the control shaft 8.

[0052] The adjusting arm 9 is controlled by a power mechanism, and the rotation of the adjusting arm 9 is controlled to drive the control shaft 8 fixedly connected at its end to rotate. The rotating control shaft 8 drives all the protrusions 7 passing through it to drive the extension rod 4 to deflect, thereby controlling the extension rod 4 to adjust the distance between the rotating end of the extension rod 4 and the ground according to the rotation adjustment of the hinged end.

[0053] According to the attached Figure 4 As shown, a fixed block 10 is fixedly connected to the side of the sowing conveyor belt 2, and a partition 11 is hingedly provided on the side of the fixed block 10. The partition 11 hinged on the side of the fixed block 10 can rotate according to the hinge axis. The rotating partition 11 is convenient for avoiding obstacles and is also convenient for folding to reduce the space occupied by the equipment.

[0054] A first spring 12 is arranged between the fixed block 10 and the partition 11. The partition 11 and the fixed block 10 are tightened by the first spring 12. The partition 11 automatically resets after crossing the obstacle, ensuring that the partition 11 separates the side space of the sowing conveyor belt 2. The potatoes falling on the side of the sowing conveyor belt 2 are blocked by the partition 11 and will not roll due to the inclined conveyance, thereby ensuring the stability of potato planting and ensuring that the potato buds are planted upward.

[0055] According to the attached Figure 5 and attached Figure 6 As shown, a feed rod 13 is inserted into the side of the material box 1 corresponding to the discharge port, and second gears 14 are provided at both ends of the feed rod 13. A discharge track 15 is meshed with the second gear 14 on the side of the feed rod 13, and the shift rod 3 is hingedly provided on the side of the discharge track 15.

[0056] A plurality of levers 3 are arranged at a certain installation interval on the side of the discharge track 15, and the material in the material box 1 is pushed at a certain time interval through the periodic operation of the discharge track 15. The advance rod 13 slides and advances in the material box 1 through the action of the driving structure to ensure the discharge of the material stored in the material box 1.

[0057] A baffle 16 is fixedly connected to the outer side of the advance rod 13 corresponding to the lever 3. When the discharge track 15 drives the lever 3 to periodically push the material in the material box 1, the material moves along the baffle 16 to the discharge port of the material box 1 under the action of the baffle 16, thereby preventing the pushing action from pushing the material out of the action range and affecting the implementation of the discharge.

[0058] A second spring 17 is arranged between the discharging track 15 and the lever 3. A contact rubber pad 18 is fixedly arranged at an inverse angle on the side of the lever 3 away from the second spring 17. A soft contact rubber pad 18 is arranged on the side of the lever 3 to ensure the pushing effect on the material while avoiding hard contact to damage the buds on the surface of the potato. A second spring 17 is arranged between the discharging track 15 and the lever 3. After the lever 3 pushes the potato to the inside of the baffle 16, the lever 3 is hindered by the material and a force is applied to the second spring 17. The second spring 17 is compressed, and the lever 3 is deflected to avoid the potato, thereby avoiding damage to the buds on the surface of the potato and ensuring the pushing and squeezing effect on the potato inside the baffle 16.

[0059] According to the attached Figure 7 and attached Figure 8 As shown, a slide groove 19 is provided on the upper surface of the feed rod 13 along the feed direction, and a driving shaft 20 is inserted into the inner side of the slide groove 19. The driving shaft 20 is rotatably connected to the material box 1, and the feed rod 13 is driven by the driving shaft 20 for engagement.

[0060] The drive of the driving shaft 20 is actively controlled by another set of driving structure. When the driving shaft 20 rotates, the advance rod 13 is driven by the engagement to advance along the direction of the slide groove 19 toward the inside of the material box 1, ensuring the use of the side lever 3 of the advance rod 13 for material discharge. When the worker finds that the lever 3 can no longer guarantee the discharge supply, the advance rod 13 is actively controlled to advance toward the inside of the material box 1.

[0061] A third gear 21 is sleeved on the side of the driving shaft 20 , and a rack 22 is fixedly provided on the inner wall of the slide slot 19 corresponding to the third gear 21 . When the driving shaft 20 rotates, the advancing rod 13 is driven to advance through the meshing action with the rack 22 .

[0062] A locking slider 23 is rotatably sleeved on the side of the driving shaft 20 and located outside the third gear 21. The locking slider 23 is rotatably sleeved on the side of the driving shaft 20 to cover one side of the third gear 21. When the driving shaft 20 rotates, the third gear 21 is prevented from contacting the inner wall of the slide groove 19 and is pressed against the inner wall of the slide groove 19 to ensure that the driving shaft 20 drives the advance rod 13 smoothly.

[0063] A roller 24 is provided on the inner wall of the sliding groove 19 on the side of the pressing slide block 23 , and the sliding friction is converted into rolling friction by the roller 24 , thereby reducing the wear of the sliding groove 19 and the pressing slide block 23 .

[0064] A guide rod 25 is also provided on the inner side of the slide groove 19, and the guide rod 25 is fixedly connected to the inner wall of the material box 1. The guide rod 25 cooperates with the driving shaft 20 to perform two-point positioning on the advance rod 13, avoiding the instability of the advance direction of the advance rod 13 caused by single-point positioning.

[0065] A method for using an adjustable potato planting device, wherein potatoes are planted using the planting device, and the steps are as follows:

[0066] S1. Since the potato skin softens after germination and the potatoes are sticky to each other, the sprouted potatoes are placed in the material box 1 in a stable manner, and the starting position of the lever 3 is adjusted;

[0067] S2. After the carrier is installed and enters the planting area, the adjusting arm 9 is driven to rotate by the power member according to the depth of the planting ridge, and the control shaft 8 fixedly connected to the adjusting arm 9 drives all the extension rods 4 on its side to rotate according to the hinge point. The rotating end of the extension rod 4 is close to the ground in the planting ridge, and the bulbs are transported to the planting ridge for planting, so as to avoid rolling and damaging the surface buds when the bulbs are planted;

[0068] S3, the carrier carries the planting equipment forward, and adjusts the rotation speed of the sowing conveyor belt 2 according to the forward speed to control the planting density of potatoes in accordance with the moving speed of the carrier;

[0069] S4, adjusting the advance movement of the lever 3 according to the rotation speed of the sowing conveyor belt 2 to ensure the delivery and supply of the bulbs in the material box 1;

[0070] S5. Use machinery or manual labor to cover the planting ridges to complete the potato planting without damage. You can also install a structure with a soil covering function behind the equipment to complete the planting operation at one time.

[0071] The present invention discloses an adjustable potato planting device and method thereof, which have the following beneficial effects:

[0072] The adjustable potato planting equipment and method thereof meet the planting needs of potato sprouting bulbs. A sowing conveyor belt 2 with adjustable extension height is arranged behind a material box 1 discharge port to ensure smooth material transportation. A lever 3 for separating bulbs and pushing the transportation is arranged in the material box 1. At the same time, a buffer structure is used to ensure the safety of bud points on the surface of potato bulbs, to avoid rolling of potato bulbs during planting, and to avoid squeezing and colliding with the conveying structure to damage the bud points on the surface of the bulbs, to ensure that the bud points on the surface of the planted potato bulbs face upward, thereby maximizing the survival rate of potato planting.

[0073] Furthermore, a lever 3 for squeezing out the potato bulbs is provided in the material box 1, so as to avoid the potato bulbs from rolling over and damaging the surface buds in the material box 1 during the discharging process. In addition, a partition 11 and other structures are provided on the side of the sowing conveyor belt 2 to ensure that the potato bulbs will not roll over due to the inclined conveying method, so as to ensure that the potatoes are planted with the buds facing upward, thereby ensuring the planting survival rate.

[0074] Furthermore, the lever 3 is configured as a hinged structure, and a soft contact rubber pad 18 with increased friction is provided on the side in contact with the potato bulbs. Combined with the second spring 17 provided on the other side, it is ensured that the lever 3 pushes the potato bulbs without damage. In addition, a baffle 16 is fixedly provided on the outer side of the advancement end of the advancement rod 13, which cooperates with the lever 3 to push the potato bulbs, ensuring that the lever 3 pushes the potato bulbs without damage to the discharge port for discharge.

[0075] Furthermore, the advance rod 13 is driven to advance through the inner meshing driving shaft 20, and the outer bearing sleeve of the third gear 21 meshing with the advance rod 13 is pressed against the slider 23 against the inner side of the slide groove 19, combined with the guide rod 25 fixed on the inner wall of the material box 1, to ensure the smooth driving and advancement of the advance rod 13.
