Description

Technical Field

[0001] This invention relates to the field of agricultural machinery parts technology, and in particular to an integrated tobacco planting and fertilization machine. Background Technology

[0002] As an important economic crop, the efficiency and quality of tobacco cultivation are crucial. In traditional tobacco cultivation, land preparation, fertilization, and sowing are mostly done independently, requiring significant manpower, resources, and time. This not only increases production costs but also makes the cultivation results susceptible to problems due to poor coordination between these stages. Furthermore, obstacles and uneven soil conditions can hinder tobacco root growth and reduce survival rates. Uneven fertilizer application and inconsistent sowing depth are also common, leading to uneven tobacco growth. Therefore, developing an integrated tobacco cultivation and fertilization machine that combines land preparation, fertilization, and sowing functions is essential.

[0003] Patent publication number CN104904380A discloses a fertilization device for an integrated tobacco planting machine. The bottom of the fertilizer box is equipped with a fertilizer distribution device, one end of which has a fertilizer adjustment knob. The bottom of the fertilizer distribution device is connected to a fertilizer pipe. Multiple fertilizer distribution devices are used, and the fertilizer pipe correspondingly has multiple upper pipes connected to the fertilizer distribution devices, with a lower pipe at the bottom. Each upper pipe has a switch plate. This patent provides a fertilization device for an integrated tobacco planting machine. By adopting the above structure, the fertilizer application rate can be adjusted via the fertilizer adjustment knob. In a further preferred embodiment, the presence of a partition allows for the simultaneous application of different fertilizers. When planting other crops, sowing can even be performed simultaneously with fertilization.

[0004] The existing technology has the following drawbacks:

[0005] Lack of land preparation before fertilization and planting: The land often contains obstacles such as stones and weed roots. If the land is not prepared before fertilization and planting, it will affect the use of tools and the growth of tobacco roots. Moreover, the soil is compacted and has poor aeration and permeability, which inhibits the respiration of tobacco roots. Existing facilities lack efficient land preparation equipment and often rely on manual labor, which is inefficient, costly and difficult to completely remove obstacles and level the land. Ultimately, this reduces the yield and quality of tobacco and reduces the economic benefits for tobacco farmers.

[0006] Unable to level and fill raised and sunken soil: The land surface is uneven, with soil accumulating in raised areas and forming pits in sunken areas. When the integrated machine is in operation, raised parts are prone to excessive wear on equipment parts, while sunken parts may lead to inconsistent fertilization and sowing depths. The existing equipment lacks an effective leveling and filling device, and cannot accurately deal with different degrees of raised and sunken areas. This results in uneven tobacco planting depth and fertilizer distribution, affecting seed germination and seedling growth, leading to uneven tobacco growth and reducing overall yield and quality. Summary of the Invention

[0007] Given the shortcomings of existing technologies, such as the lack of land preparation before fertilization and the inability to level and fill uneven and sunken soil, an integrated tobacco planting and fertilization machine is proposed.

[0008] This application provides an integrated tobacco planting and fertilization machine, the purpose of which is to comprehensively address land issues through its land preparation mechanism. On the one hand, it can remove obstacles such as stones and weed roots from the land, loosen compacted soil, improve soil aeration and permeability, and ensure the normal growth of tobacco roots. On the other hand, it can precisely level and fill the protrusions and depressions on the land surface, making the land level. This achieves the effects of improving land preparation efficiency, reducing labor costs, avoiding excessive equipment wear, and ensuring the quality of fertilization and sowing, ultimately achieving uniform tobacco growth, increased yield and quality, and increased economic benefits for tobacco farmers.

[0009] The technical solution of the present invention is as follows: a tobacco planting and fertilization integrated machine, including a driving device and a connecting component disposed on one side of the driving device, the connecting component including a frame hinged to the driving device, and a land preparation mechanism disposed at the bottom of the frame;

[0010] The land preparation mechanism includes a connecting shaft hinged to the bottom of the frame. An obstacle removal component is fixedly connected to the bottom of the connecting shaft. The obstacle removal component contains a plowing component and a swinging component. The obstacle removal component and the swinging component are used to collect and remove obstacles. The plowing component is used to loosen the soil and block obstacles.

[0011] The obstacle removal assembly includes an obstacle removal box fixedly connected to the bottom of the connecting shaft. Two obstacle removal slots are symmetrically arranged on both sides of the obstacle removal box. Two sliding baffles are slidably connected to the outer walls of both sides of the obstacle removal box. The sliding baffles are arranged outside the corresponding obstacle removal slots.

[0012] Using the above scheme, through the set obstacle removal component, plowing component and swinging component, during operation, the plowing component loosens the soil as it moves forward, and at the same time digs out obstacles such as branches and stones. The obstacles are temporarily stored in the obstacle removal box through the plowing component; when the drive device needs to turn, the obstacle removal box is lifted by the frame, and the sliding baffles on both sides slide under the action of gravity to expose the obstacle removal groove; the obstacle removal box is discharged by the swinging component.

[0013] Furthermore, the swing assembly includes a swing box fixedly connected to the inner wall of the obstacle removal box, a gravity ball is rolled on the inner wall of the swing box, and two symmetrically arranged inclined plates are fixedly connected to the inner wall of the swing box.

[0014] Using the above scheme, when the drive device needs to turn, the obstacle removal box is lifted by the frame through the swing component, and the sliding baffles on both sides slide to expose the obstacle removal groove under the action of gravity; at this time, the gravity ball will also break away from the limit of the two inclined plates and roll freely in the swing box; when the drive device turns, the gravity ball will be deflected to the outside under the action of centrifugal force, causing the obstacle removal box to tilt at the connecting shaft, thereby expelling the obstacles in the obstacle removal box.

[0015] Furthermore, the tilling assembly includes multiple inner soil loosening claws fixedly connected to the bottom of the obstacle removal box. The bottom of the obstacle removal box has multiple telescopic grooves, and outer soil loosening claws are slidably connected inside each of the multiple telescopic grooves. A telescopic spring is fixedly connected between the outer soil loosening claws and the inner wall of the telescopic groove. The multiple outer soil loosening claws and multiple inner soil loosening claws are alternately arranged, and multiple ground-inserting blades are fixedly connected to the bottom of each of the outer soil loosening claws and inner soil loosening claws.

[0016] Furthermore, the obstacle removal assembly also includes two rubber pads fixedly connected to the top of the obstacle removal box and arranged symmetrically, and the inner wall of the obstacle removal box has multiple soil leakage holes.

[0017] Using the above scheme, the soil-loosening components, with the soil-inserting blades at the bottom of the inner and outer soil-loosening claws, are inserted into the soil to loosen it as they move forward, while simultaneously removing obstacles such as branches and stones. Branches and smaller stones are temporarily stored in the obstacle removal box along the inclined inner and outer soil-loosening claws, while larger stones will squeeze the outer soil-loosening claws, causing them to retract into the telescopic groove and merge with the inner soil-loosening claws on both sides, allowing the larger stones to roll into the obstacle removal box along the larger surface.

[0018] Furthermore, a leveling component is fixedly connected to the side of the obstacle removal box away from the plowing component, and two soil filling components are symmetrically arranged inside the leveling component.

[0019] Furthermore, the leveling assembly includes a soil storage box fixedly connected to the outer wall of the obstacle removal box, two symmetrically arranged soil discharge channels are provided on both sides of the soil storage box, a ground-feeding shovel is fixedly connected to the bottom of the soil storage box, and a protrusion is fixedly connected to the inner wall of the soil storage box.

[0020] Using the above scheme, the leveling component will scoop up the raised soil and put it into the soil storage box when encountering raised soil during operation. The soil in the storage box will accumulate on both sides of the storage box along the guide of the raised blocks as it moves forward, providing raw materials for filling depressions later. If there is too much raised soil, the excess soil will be discharged to the outside of the frame through the soil discharge channels on both sides of the storage box to avoid affecting the path of fertilization and sowing.

[0021] Furthermore, the backfilling assembly includes a retaining plate fixedly connected to the inner wall of the soil storage box, and a grooving plate and a soil unloading plate are rotatably connected to the bottom of the soil storage box. The soil unloading plate is positioned above the grooving plate, and a soil unloading groove is formed on the inner wall of the soil unloading plate.

[0022] Using the above scheme, when the soil filling component is set up and encounters a depression in the soil along the fertilization and sowing path during operation, the grooving plate will first sink into the depression, and the soil unloading plate will then open to expose the soil unloading trough. This allows the soil on both sides of the soil storage box to fill the depression. At the same time, the retaining wall around the soil unloading plate can prevent too much soil from filling the depression and causing blockage of the soil unloading trough.

[0023] Furthermore, a fertilization device and a sowing assembly are fixedly connected to the outer wall of the frame, with the fertilization device located between the sowing assembly and the drive device.

[0024] Furthermore, the seeding assembly includes two grooving devices and two seeding devices fixedly connected to the outer wall of the frame. The seeding devices are located above the grooving devices. A soil covering device and a pressing wheel are fixedly connected to the outer wall of the grooving device. The soil covering device is located between the pressing wheel and the grooving device.

[0025] Using the above scheme, after the land is prepared, the fertilizer application device on the outer wall of the machine frame begins to spread fertilizer evenly on the prepared land through the fertilizer application device and the sowing component. Then, the sowing component starts to work. The grooving device opens a sowing groove in the land, the sowing device sows tobacco seeds into the groove, the soil covering device then covers the seeds with soil, and finally the pressing wheel presses the covered soil to make the seeds in close contact with the soil, creating good conditions for seed germination and growth.

[0026] Furthermore, the connecting assembly also includes a rotating hydraulic cylinder fixedly connected to the outer wall of the drive device. The output end of the rotating hydraulic cylinder is fitted with a rotating shaft, and the inner wall of the rotating shaft is provided with a connecting groove, which is hinged to the frame.

[0027] Using the above scheme, the drive unit provides power through the set connection components, which moves the equipment in the field; and the rotating shaft is driven to rotate by rotating the hydraulic cylinder to adjust the angle of the frame, so that the frame contacts the ground during operation and tilts the frame when turning.

[0028] The beneficial effects of this invention are:

[0029] The obstacle removal component, plowing component, and swinging component work together. The inner and outer loosening claws of the plowing component insert the cutting blades at the bottom of the claws into the soil. As it moves forward, it loosens the soil and removes obstacles such as branches and stones. Branches and small stones are temporarily stored in the obstacle removal box along the surface. Large stones are pushed into the telescopic groove by the outer loosening claws and then rolled in. When the drive unit turns, the obstacle removal box is lifted, and the sliding baffle exposes the obstacle removal groove. The gravity ball of the swinging component tilts the obstacle removal box under the action of centrifugal force to remove obstacles. This completely removes obstacles from the land, loosens compacted soil, improves aeration and permeability, ensures the normal growth of tobacco roots, improves land preparation efficiency, and reduces labor costs.

[0030] By working together with the leveling and filling components, the leveling component's ground-hugging shovel scoops up raised soil and puts it into the soil storage box. The soil accumulates along the raised blocks to both sides, and excess soil is discharged from the discharge chute. When the filling component encounters depressed soil, the grooving plate sinks in, and the unloading plate opens to expose the unloading chute, allowing the soil on both sides of the soil storage box to fill the depression. The retaining plate prevents excessive soil from clogging the unloading chute. This avoids excessive wear on the equipment parts caused by the raised parts during the operation of the integrated machine, ensures consistent fertilization and sowing depth, prevents uneven tobacco planting depth and fertilizer distribution, and makes tobacco grow more uniformly.

Detailed Implementation

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 - Figure 12 A tobacco planting and fertilization integrated machine is provided, including a drive unit 1 and a connecting component 2 disposed on one side of the drive unit 1. The connecting component 2 includes a frame 24 hinged to the drive unit 1, and a land preparation mechanism 3 is disposed at the bottom of the frame 24.

[0047] Reference Figure 4 - Figure 8The land preparation mechanism 3 includes a connecting shaft 31 hinged to the bottom of the frame 24. A barrier removal component 32 is fixedly connected to the bottom of the connecting shaft 31. The barrier removal component 32 is equipped with a plowing component 34 and a swinging component 35. The barrier removal component 32 and the swinging component 35 are used to collect and remove obstacles. The plowing component 34 is used to loosen the soil and block obstacles. The barrier removal component 32 includes a barrier removal box 321 fixedly connected to the bottom of the connecting shaft 31. Two symmetrically arranged obstacle removal slots 325 are opened on both sides of the barrier removal box 321. Two symmetrically arranged sliding baffles 324 are slidably connected to the outer walls of both sides of the barrier removal box 321. The sliding baffles 324 are arranged outside the corresponding obstacle removal slots 325.

[0048] Specifically, the obstacle removal box 321 is provided with a sliding groove on its exterior, and the sliding baffle 324 slides along the sliding groove; when the frame 24 is on the ground, the sliding baffle 324 closes the obstacle removal groove 325 under the action of gravity; when the frame 24 is lifted, the sliding baffle 324 slides in the opposite direction under the action of gravity to expose the obstacle removal groove 325.

[0049] With the obstacle removal component 32, the plowing component 34, and the swinging component 35 in place, during operation, the plowing component 34 loosens the soil as it moves forward, and at the same time digs out obstacles such as branches and stones. The obstacles are temporarily stored in the obstacle removal box 321 through the plowing component 34. When the drive device 1 needs to turn, the obstacle removal box 321 is lifted by the frame 24, and the sliding baffles 324 on both sides slide under the action of gravity to expose the obstacle removal groove 325. The obstacle is then discharged from the obstacle removal box 321 by the swinging component 35.

[0050] Reference Figure 7 - Figure 8 The swing assembly 35 includes a swing box 351 fixedly connected to the inner wall of the obstacle removal box 321. A gravity ball 353 is rolled on the inner wall of the swing box 351, and two symmetrically arranged inclined plates 352 are fixedly connected to the inner wall of the swing box 351.

[0051] Specifically, when the frame 24 is on the ground, the two inclined plates 352 limit the gravity ball 353. No matter how the frame 24 shakes, the gravity ball 353 always rolls towards the center. When the frame 24 is lifted, the bottom of the gravity ball 353 is no longer the inclined plate 352, but the smooth inner wall of the swing box 351. When the drive device 1 drives the frame 24 to turn, the gravity ball 353 will roll outward with centrifugal force, causing the obstacle removal box 321 to tilt.

[0052] When the drive unit 1 needs to turn, the obstacle removal box 321 is lifted by the frame 24 via the swing component 35. The sliding baffles 324 on both sides slide to expose the obstacle removal groove 325 under the action of gravity. At this time, the gravity ball 353 will also break away from the limit of the two inclined plates 352 and roll freely in the swing box 351. When the drive unit 1 turns, the gravity ball 353 will be deflected to the outside under the action of centrifugal force, causing the obstacle removal box 321 to tilt at the connecting shaft 31, thereby expelling the obstacles in the obstacle removal box 321.

[0053] Reference Figure 5 - Figure 8 The plowing assembly 34 includes multiple inner soil loosening claws 341 fixedly connected to the bottom of the obstacle removal box 321. The bottom of the obstacle removal box 321 has multiple telescopic grooves 344. The inner side of each telescopic groove 344 is slidably connected to an outer soil loosening claw 342. A telescopic spring 343 is fixedly connected between the outer soil loosening claw 342 and the inner wall of the telescopic groove 344. The multiple outer soil loosening claws 342 and the multiple inner soil loosening claws 341 are alternately arranged. The bottom of each outer soil loosening claw 342 and the inner soil loosening claw 341 is fixedly connected to multiple ground-inserting blades 345. The obstacle removal assembly 32 also includes two rubber pads 322 fixedly connected to the top of the obstacle removal box 321 and arranged symmetrically. The inner wall of the obstacle removal box 321 has multiple soil-draining holes 323.

[0054] Specifically, the outer soil loosening claw 342 and the inner soil loosening claw 341 are alternately set, so that the outer soil loosening claw 342 can be retracted to merge with the inner soil loosening claw 341 into one piece to deal with larger stones; the front edge of the ground-inserting knife 345 is set to be arc-shaped, and the bottom is set to be blade-shaped, so that the soil loosening claw can be inserted into the soil and break the soil more easily.

[0055] The soil-plowing component 34, with its inner loosening claw 341 and outer loosening claw 342 having its bottom cutting blades 345 inserted into the soil, loosens the soil as it moves forward, while simultaneously removing obstacles such as branches and stones. Branches and smaller stones are temporarily stored in the obstacle removal box 321 along the inclined inner and outer loosening claws 341 and 342, while larger stones will press against the outer loosening claw 342, causing it to retract into the telescopic groove 344 and merge with the inner loosening claws 341 on both sides, allowing larger stones to roll into the obstacle removal box 321 along the larger surface.

[0056] Reference Figure 9 - Figure 11 A leveling component 33 is fixedly connected to the side of the obstacle removal box 321 away from the plowing component 34. Two soil filling components 36 are symmetrically arranged inside the leveling component 33. The leveling component 33 includes a soil storage box 331 fixedly connected to the outer wall of the obstacle removal box 321. Two soil discharge troughs 332 are symmetrically arranged on both sides of the soil storage box 331. A ground-feeding shovel 333 is fixedly connected to the bottom of the soil storage box 331. A protrusion 334 is fixedly connected to the inner wall of the soil storage box 331.

[0057] When encountering raised soil during operation, the ground scraper 333 scoops up the raised soil and puts it into the soil storage box 331. The soil in the soil storage box 331 will accumulate on both sides of the soil storage box 331 along the guide of the protrusion 334 during the forward movement, providing raw materials for subsequent filling of depressions. If there is too much raised soil, the excess soil will be discharged to the outside of the frame 24 through the soil discharge troughs 332 on both sides of the soil storage box 331, so as to avoid affecting the path of fertilization and sowing.

[0058] Reference Figure 10 - Figure 11 The backfilling assembly 36 includes a retaining plate 361 fixedly connected to the inner wall of the soil storage box 331. The bottom of the soil storage box 331 is rotatably connected to a grooving plate 362 and a soil unloading plate 363. The soil unloading plate 363 is located above the grooving plate 362, and a soil unloading groove 364 is provided on the inner wall of the soil unloading plate 363.

[0059] When the soil filling component 36 is set up, the grooving plate 362 will first sink into the soil depression when encountering depressions in the fertilization and sowing path during operation. The soil unloading plate 363 will then open, exposing the soil unloading trough 364, so that the soil on both sides of the soil storage box 331 can be filled into the depression. At the same time, the soil retaining plate 361 around the soil unloading plate 363 can prevent the soil unloading trough 364 from being blocked by too much soil filling the depression.

[0060] Reference Figure 1 - Figure 3 The outer wall of the frame 24 is fixedly connected to a fertilizer applicator 4 and a seeding assembly 5. The fertilizer applicator 4 is located between the seeding assembly 5 and the drive device 1. The seeding assembly 5 includes two grooving devices 52 and two seeding devices 51 fixedly connected to the outer wall of the frame 24. The seeding devices 51 are located above the grooving devices 52. The outer wall of the grooving device 52 is fixedly connected to a soil covering device 53 and a pressing wheel 54. The soil covering device 53 is located between the pressing wheel 54 and the grooving device 52.

[0061] After the land is prepared, the fertilizer application device 4 on the outer wall of the frame 24 begins to spread fertilizer evenly on the prepared land through the fertilizer application device 4 and the sowing component 5. Then, the sowing component 5 starts to work. The slotter 52 opens a sowing slot on the land, the sowing device 51 sows tobacco seeds into the slot, the soil covering device 53 then covers the seeds with soil, and finally the pressing wheel 54 presses the covered soil to make the seeds in close contact with the soil, creating good conditions for seed germination and growth.

[0062] Reference Figure 2 - Figure 4The connecting component 2 also includes a rotating hydraulic cylinder 21 fixedly connected to the outer wall of the drive device 1. The output end of the rotating hydraulic cylinder 21 is fitted with a rotating shaft 22. The inner wall of the rotating shaft 22 is provided with a connecting groove 23, which is hinged to the frame 24.

[0063] The drive unit 1 provides power through the connection component 2, which drives the equipment to move in the field; and the rotating shaft 22 is rotated by rotating the hydraulic cylinder 21 to adjust the angle of the frame 24, so that the frame 24 contacts the ground during operation and tilts the frame 24 when turning.

[0064] Working principle of the invention:

[0065] During operation, the drive unit 1 provides power to move the equipment in the field; and by rotating the hydraulic cylinder 21, it drives the rotating shaft 22 to rotate to adjust the angle of the frame 24, so that the frame 24 contacts the ground during operation and tilts the frame 24 when turning.

[0066] During operation, the ground-inserting blades 345 at the bottom of the inner soil-loosening claws 341 and the outer soil-loosening claws 342 are inserted into the soil to loosen the soil as they move forward, while simultaneously removing obstacles such as branches and stones. Branches and smaller stones are temporarily stored in the obstacle removal box 321 along the inclined inner soil-loosening claws 341 and the outer soil-loosening claws 342, while larger stones will squeeze the outer soil-loosening claws 342, causing them to retract into the telescopic groove 344 and merge with the inner soil-loosening claws 341 on both sides, allowing larger stones to roll into the obstacle removal box 321 along the larger surface.

[0067] The loose soil that enters the obstacle removal box 321 with the obstacle is discharged into the soil storage box 331 through the soil leakage hole 323, leaving obstacles such as branches and stones. When the drive device 1 needs to turn, the obstacle removal box 321 is lifted by the frame 24, and the sliding baffles 324 on both sides slide to expose the obstacle removal groove 325 under the action of gravity. At this time, the gravity ball 353 will also break away from the limit of the two inclined plates 352 and roll freely in the swing box 351. When the drive device 1 turns, the gravity ball 353 will be deflected to the outside under the action of centrifugal force, causing the obstacle removal box 321 to tilt at the connecting shaft 31, thereby expelling the obstacle in the obstacle removal box 321.

[0068] When encountering raised soil during operation, the ground scraper 333 scoops up the raised soil and puts it into the soil storage box 331. The soil in the soil storage box 331 will accumulate on both sides of the soil storage box 331 along the guide of the protrusion 334 during the forward movement, providing raw materials for subsequent filling of depressions. If there is too much raised soil, the excess soil will be discharged to the outside of the frame 24 through the soil discharge troughs 332 on both sides of the soil storage box 331 to avoid affecting the path of fertilization and sowing.

[0069] When encountering depressions in the fertilization and sowing path during operation, the grooving plate 362 will first sink into the depression, and the unloading plate 363 will then open to expose the unloading trough 364, thereby filling the depression with soil from both sides of the soil storage box 331. At the same time, the retaining wall 361 around the unloading plate 363 can prevent the unloading trough 364 from being blocked by too much soil filling the depression.

[0070] After the land is prepared, the fertilization device 4 on the outer wall of the frame 24 begins to spread fertilizer evenly on the prepared land; then, the sowing component 5 begins to operate, the grooving device 52 opens a sowing groove on the land, the sowing device 51 sows tobacco seeds into the groove, the soil covering device 53 then covers the seeds with soil, and finally the pressing wheel 54 presses the covered soil to make the seeds in close contact with the soil, creating good conditions for seed germination and growth.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
