Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery and equipment technology, and specifically provides a tobacco rotary tillage, ridging and fertilization machine. Background Technology
[0002] In tobacco cultivation, rotary tillage and ridging are crucial preliminary steps. A ridge that meets agronomic requirements should have an appropriate height, a full curvature, and a consistent width. This directly affects the soil's aeration, drainage, moisture retention, and the development environment of the tobacco plant's root system, ultimately influencing the yield and quality of the tobacco leaves.
[0003] Currently, tobacco growers widely use walk-behind rotary tillers. These machines are typically powered by a walk-behind tractor, which drives the rotary tiller rollers via a drive shaft to break up the soil and prepare the land initially. The subsequent connecting ridging plow or shaping cover completes the ridging and hilling operations.
[0004] However, existing walk-behind rotary tillers have significant drawbacks in practical applications: poor adaptability to ridge shapes. Because the structure and dimensions of their ridging components are typically fixed, a single machine can only create ridges of a fixed width and curvature, making it impossible to flexibly adjust to different soil characteristics or specific agronomic requirements of different tobacco varieties (e.g., wide ridges are needed in heavy clay soils to facilitate drainage, while high, narrow ridges are needed in sandy soils to retain moisture). Furthermore, when different ridge sizes are needed on the same plot of land, the user must stop the machine and replace the entire ridging component, a time-consuming and labor-intensive process that reduces operational efficiency. Therefore, existing walk-behind rotary tillers cannot meet the urgent needs of refined and standardized tobacco cultivation for adjustable ridge parameters and high-quality ridges. Utility Model Content
[0005] To address the aforementioned problems, this invention provides an innovative device that allows for convenient adjustment of the ridge width and curvature, and effective shaping and compaction of the ridge soil to adapt to different ridge height requirements. The specific technical solution is as follows: A tobacco rotary tillage and ridge-forming fertilizer applicator includes a drive frame with a handrail. From front to back, the drive frame is sequentially equipped with a drive wheel, a rotary tillage assembly, a fertilizer applicator, and a ridge-forming cover. The ridge-forming cover includes an arc-shaped ridge plate, a vertically arranged connecting column, and a horizontal adjusting rod fixedly attached to the connecting column. The arc-shaped ridge plate is fixedly connected to the bottom of the connecting column. Vertical guide rods are symmetrically arranged at both ends of the horizontal adjusting rod. The upper end of the guide rod is slidably mounted on the horizontal adjusting rod, and a guide wheel is provided at the lower end of the guide rod. Both ends of the arc-shaped ridge plate are respectively mounted on the guide rod. When the ridge-forming cover is in operation, a ridge is formed on the inner side of the arc-shaped ridge plate.
[0006] Compared to existing tobacco ridging equipment, the forming cover structure provided in this solution utilizes the flexibility of the curved ridge plate. By adjusting the distance between the two guide rods, the position of both ends of the curved ridge plate can be adjusted, thereby adjusting the forming curvature of the entire curved ridge plate. This ensures that the width of the ridge formed by the forming cover meets the requirements. It can quickly and efficiently adapt to different ridges without stopping the machine to manually replace the entire ridging component. The rotary tillage component is located in front of the fertilization component, which can spread fertilizer on the ground after rotary tillage and before ridging. The fertilizer is then buried under the ridge body during the ridging operation, which can cleverly apply base fertilizer. At the same time, the guide wheels can avoid direct friction between the ends of the curved ridge plate and the ground, ensuring convenient daily movement of the equipment and avoiding excessive wear on the curved ridge plate.
[0007] To further adapt to the requirements of ridging at different heights, preferably, the guide rod is a telescopic rod with a self-locking structure, and the arc-shaped ridge board includes an arc-shaped mounting main board and a side adjustment plate. The side adjustment plate is symmetrically and slidably disposed on both sides of the mounting main board. The highest point of the mounting main board is connected to the connecting column, and the outermost end of the side adjustment plate is connected to the lowest end of the guide rod.
[0008] In this design, when the guide rod moves left and right to adjust the distance, the side adjustment plate can be pulled out or pushed in from the mounting plate, thus ensuring that the height of the ridges formed by the curved ridge plate is consistent after adjusting the curvature and width of the curved ridge plate. Similarly, by adjusting the length of the guide rod, the side adjustment plate can also be pulled out or pushed in from the mounting plate, and the height of the ridge plate can also be adjusted. This achieves the adjustment of the height, curvature, and width of the ridge, thereby improving the adaptability of the entire ridge cover.
[0009] Preferably, the two long sides of the mounting motherboard are folded outward to form a C-shaped outward fold, and the side adjustment plate is slidably connected to the mounting motherboard through the C-shaped outward fold.
[0010] Preferably, an adjusting stud is fixedly provided on the side adjusting plate, and an adjusting strip hole is provided on the C-shaped outward-facing side adjusting plate along the sliding direction of the side adjusting plate. The adjusting stud extends out from the adjusting strip hole and can be locked in the position of the adjusting stud in the adjusting strip hole by bolts.
[0011] Preferably, the side adjustment plate is provided with a reinforcing rib along its width direction, and the side adjustment plate is connected to the guide rod through the reinforcing rib.
[0012] To further improve the adaptability of the forming ridge cover, preferably, the tail of the drive frame is provided with a connecting sleeve that is adapted to the connecting column. The connecting sleeve can be slidably fitted onto the outside of the connecting column. The connecting column is provided with a plurality of first fixed-distance through holes along its length direction, and the connecting sleeve is provided with a plurality of second fixed-distance through holes. When the connecting sleeve is fitted onto the outside of the connecting column, at least one first fixed-distance through hole and one second fixed-distance through hole are coaxially arranged, and the relative position of the connecting sleeve and the connecting column can be fixed by inserting a locking pin.
[0013] In this solution, by controlling the position of the connecting column in the connecting sleeve column, the height of the entire forming cover can be adjusted, thereby adapting to different rotary tillage components. At the same time, by adjusting the height of the entire forming cover, it is possible to avoid the arc-shaped ridge board being damaged due to being too close to the ground or the ridge being loose due to being too far from the ground, which could lead to the collapse of the ridge.
[0014] Preferably, an adjusting sleeve is fixedly provided on the top of the guide rod. The inner diameter of the adjusting sleeve is adapted to the shape and size of the horizontal adjusting rod. The adjusting sleeve is sleeved on the outside of the horizontal adjusting rod to achieve a sliding connection. A locking hole is provided on the surface of the adjusting sleeve. The adjusting sleeve is positioned by inserting a locking pin or a locking screw into the locking hole.
[0015] Preferably, the connecting column and / or the horizontal adjusting rod are polygonal prisms to ensure that the connecting sleeve or adjusting sleeve does not rotate during sliding, thus ensuring stability during sliding and positioning.
[0016] Preferably, a baffle plate is provided on the side of the arc-shaped ridge facing the rotary tillage assembly, and the baffle plate is fixedly connected to the horizontal adjustment rod.
[0017] Preferably, the mounting motherboard is provided with a plurality of secondary reinforcing ribs, which are arranged along the arched axial direction of the mounting motherboard.
[0018] The beneficial effects of this utility model are: This invention utilizes an adjustable ridging cover structure to achieve flexible adjustment of the ridging width, curvature, and height, adapting to different soil conditions and agronomic requirements. The equipment has a simple structure and is easy to operate; parameter adjustments can be completed without replacing the entire ridging component, significantly improving operational efficiency and ridging quality. Simultaneously, the design of the guide wheels and reinforced structure reduces wear and improves the equipment's durability and ease of movement. Attached Figure Description

Detailed Implementation
[0022] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention. Example 1
[0023] A tobacco rotary tillage, ridging, and fertilizing machine, such as Figure 1 As shown, the device includes a drive frame 1 with a handrail 6, and the drive frame 1 is provided with a drive wheel 2, a fertilizer application component 3, a rotary tillage component 4 and a ridge covering 5 arranged sequentially from front to back.
[0024] Among them, such as Figures 2 to 4 As shown, the forming ridge cover 5 includes an arc-shaped ridge plate 51, a vertically arranged connecting column 52, and a horizontal adjusting rod 53 fixedly arranged with the connecting column 52. The connecting column 52 is used to connect the forming ridge cover 5 to the drive frame 1. The arc-shaped ridge plate is fixedly connected below the connecting column 52. The horizontal adjusting rod 53 has vertical guide rods 54 symmetrically arranged at both ends. The upper end of the guide rod 54 is slidably arranged on the horizontal adjusting rod. The lower end of the guide rod 54 is provided with a guide wheel 542. The two ends of the arc-shaped ridge plate 51 are respectively arranged on the guide rod 54. The two ends of the arc-shaped ridge plate 51 are respectively connected to the guide rod 54 through reinforcing ribs 511.
[0025] When the forming ridge cover 5 is in operation, a ridge platform is formed on the inner side of the arc-shaped ridge plate 51. By adjusting the distance between the two guide rods 54 on the horizontal adjusting rod 53, the unfolded width at both ends of the arc-shaped ridge plate 51 can be changed, thereby adjusting the forming arc of the arc-shaped ridge plate 51 to adapt to the requirements of different ridge widths. The guide wheels 542 can prevent the two ends of the arc-shaped ridge plate 51 from directly rubbing against the ground, reducing wear and facilitating equipment movement.
[0026] Specifically, such as Figure 3 and Figure 4 As shown, the arc-shaped mounting plate 51 includes an arc-shaped mounting main plate 512 and side adjustment plates 513 symmetrically slidably disposed on both sides of the mounting main plate 512. The highest point of the mounting main plate 512 is connected to the connecting post 52, and the outermost end of the side adjustment plate 513 is connected to the lowermost end of the guide rod 54 through a reinforcing rib plate 511. The two long sides of the mounting main plate 512, i.e., the curved edges, are folded outward to form C-shaped outward folds 514. The C-shaped outward folds 514 form a slide rail structure that guides the side adjustment plates 513, allowing the side adjustment plates 513 to slide and connect with the mounting main plate 512 through the C-shaped outward folds 514.
[0027] Of course, in order to ensure the position of the lockable side adjustment plate 513 on the mounting main plate 512, an adjustment stud 515 is fixedly provided on the side adjustment plate 513. An adjustment strip hole 516 is provided on the C-shaped outward 514 along the sliding direction of the side adjustment plate 513. The adjustment stud 515 extends out from the adjustment strip hole 516 and is locked by a nut, thereby fixing the position of the adjustment stud 515 in the adjustment strip hole 516.
[0028] Furthermore, an adjusting sleeve 541 is fixedly installed on the top of the guide rod 54. The inner diameter of the adjusting sleeve 541 is adapted to the outer diameter and shape of the horizontal adjusting rod 53. The adjusting sleeve 541 is fitted onto the horizontal adjusting rod 53 to achieve a sliding connection. A locking hole is provided on the surface of the adjusting sleeve 541. The adjusting sleeve 541 is positioned by inserting a locking pin or a locking screw into the locking hole. It should be noted that the horizontal adjusting rod 53 is a polygonal prism structure. In this embodiment, the horizontal adjusting rod 53 is a hexagonal prism, and the inner ring of the adjusting sleeve 541 is also a hexagonal prism structure to ensure that it does not rotate during sliding and to improve stability.
[0029] The guide rod 54 is a telescopic rod with a self-locking structure. This telescopic rod can use the same telescopic structure as the adjusting sleeve 541, or it can use other existing structures. When adjusting the spacing or telescopic length of the guide rod 54, the side adjustment plate 513 can be pulled out or pushed in from the mounting plate 512 accordingly, thereby maintaining the consistent height of the ridge or adjusting the height of the ridge, and realizing the comprehensive adjustment of the ridge height, curvature and width. Example 2
[0030] Based on Example 1, in order to further improve the adaptability of the molded ridge cover 5, such as... Figure 2 and Figure 3 As shown, the drive frame 1 has a connecting sleeve 11 at its tail end that is adapted to the connecting post 52. The connecting sleeve 11 can be slidably fitted onto the connecting post 52. The connecting post 52 has a plurality of first fixed-distance through holes along its length, and the connecting sleeve 11 has a plurality of second fixed-distance through holes. When the connecting sleeve 11 is fitted onto the connecting post 52, at least one of the first fixed-distance through holes and one of the second fixed-distance through holes are coaxially arranged, and the relative positions of the connecting sleeve 11 and the connecting post 52 can be fixed by inserting a locking pin. In this embodiment, the connecting post 52 is also a hexagonal prism, and the inner ring of the corresponding connecting sleeve 11 is also a hexagonal prism structure to ensure that it does not rotate during sliding and to improve stability. This embodiment controls the position of the connecting column 52 in the connecting sleeve column 11, thereby adjusting the height of the entire forming cover to adapt to different rotary tillage components 4. At the same time, by adjusting the height of the entire forming cover, it can prevent the arc-shaped ridge board 51 from being too close to the ground or the ridge from being too far from the ground, which would result in the ridge being loose and thus the ridge collapsing. Example 3
[0031] Based on the above embodiments, the mounting main plate 512 and side adjustment plate 513 in the arc-shaped ridge plate 51 are made of high-strength spring steel, possessing sufficient flexibility and wear resistance. The reinforcing ribs 511 on the side adjustment plate 513 and the secondary reinforcing ribs 518 on the mounting main plate 512 are triangular plates, connected to the guide rod 54 by bolts or direct welding. A baffle plate 517 is provided on the side of the arc-shaped ridge plate 51 facing the rotary tillage assembly 4. The baffle plate 517 is fixedly connected to the horizontal adjustment rod 53, preventing soil overflow and ensuring the fullness and uniformity of the ridge. Multiple secondary reinforcing ribs 518 are provided on the mounting main plate 512, arranged along the width direction of the mounting main plate 512 to ensure the strength of the arc-shaped ridge plate 51.
[0032] The baffle 517 consists of two symmetrical left and right plates, which are slidably fitted onto both ends of the horizontal adjusting rod 53 via baffle mounting sleeves 519. It has the same self-locking structure as the connecting sleeve 11. Secondary reinforcing ribs 518 are welded onto the mounting main plate 512 to further improve the rigidity and durability of the overall structure.
[0033] Based on the above embodiments, when using this tobacco rotary tillage ridging and fertilizing machine, first adjust the parameters of the ridge cover 5 according to the soil characteristics of the field and the agronomic requirements of the tobacco variety: Adjusting the ridge width: Loosen the locking pin of the adjusting sleeve 541, move the guide rod 54 to the position on the horizontal adjusting rod 53, change the distance between the two guide rods 54, thereby adjusting the unfolded width and curvature of the arc-shaped ridge board 51. After adjustment, insert the locking pin to fix the position of the guide rod 54.
[0034] Adjusting the ridge height: By adjusting the sliding position of the telescopic guide rod 54 or the side adjustment plate 513 in the mounting plate 512, the vertical height of the arc-shaped ridge plate 51 is changed, thereby adjusting the ridge height. After adjustment, it is locked and fixed by the self-locking structure or nuts.
[0035] Adjust the overall height: Adjust the overall height of the ridge cover 5 by sliding the connecting column 52 in the connecting sleeve 11 to adapt to different rotary tillage depths and ridge compaction requirements. After adjustment, insert the locking pin to fix it.
[0036] During operation, the rotary tillage component 4 breaks up the soil and performs preliminary land preparation, while the fertilization component 3 applies fertilizer simultaneously. The ridge-forming cover 5 shapes and compacts the soil to form ridges that meet the requirements. The guide wheel 542 reduces friction with the ground, and the baffle plate 517 prevents soil from overflowing, ensuring the fullness and consistency of the ridges.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
