Description

Technical Field

[0001] The invention relates to the technical field of planting soil covering, in particular to a rotary soil covering and compacting device. Background Art

[0002] In the traditional field of soil covering operations, simple tools such as shovels have long been used for soil covering work. This traditional operation method mainly relies on a large amount of manpower input, which makes the labor intensity extremely high. Operators need to repeat actions such as digging, carrying and covering soil for a long time, which not only consumes a lot of physical strength, but also has low work efficiency, making it difficult to meet the needs of large-scale and efficient soil covering operations.

[0003] With the continuous development and widespread application of mechanization technology, some professional soil covering devices have gradually emerged in soil covering operations. The emergence of these devices has alleviated the pressure of manual labor to a certain extent and improved work efficiency. However, there are still many problems that need to be solved in the existing soil covering devices. On the one hand, the existing soil covering devices themselves are large in size and complex in structural design. This not only leads to an increase in the manufacturing cost of the equipment, but also in actual use, the large volume will limit its operational flexibility in some places with limited space, and the complex structure also increases the difficulty and cost of equipment maintenance.

[0004] On the other hand, the existing soil covering devices still have a serious problem of insufficient backfill. In many actual soil covering operation scenarios, a sufficient amount of soil needs to be covered in a specific area to meet various needs such as soil improvement, vegetation planting, site leveling, etc. However, due to the limitations of its own design or working principle, the existing soil covering devices cannot provide sufficient backfill and are difficult to meet normal soil covering needs, resulting in poor operation results and affecting the smooth progress of subsequent work.

[0019] Preferably, the reciprocating direction of the compaction plate is an inclined direction.

[0021] Preferably, a connecting plate is fixedly provided on the supporting frame, and the connecting plate is used to be connected to the output end of the lifting drive mechanism.

[0022] Compared with the prior art, the present invention has achieved the following technical effects:

[0023] The rotary soil covering and compacting device of the present invention realizes mechanized soil covering operation by setting a rotary soil covering and compacting device. The lifting drive mechanism drives the support frame to lift, the rotary drive mechanism drives the soil covering frame to rotate along the circumference of the support frame, and the compacting mechanism compacts the soil. These mechanisms work together to greatly reduce manpower input. Operators do not need to repeat high-intensity actions such as digging, carrying and covering for a long time, which effectively reduces the intensity of manual labor and significantly improves the efficiency of soil covering operations, which can meet the needs of large-scale and high-efficiency soil covering operations.

[0024] Furthermore, the support frame of the present invention is in the shape of an open ring. This structural design is relatively simple, and the overall volume is reduced while ensuring the function of the device. At the same time, the layout of each component such as the lifting drive mechanism, the earth-sealing frame, the rotation drive mechanism and the compaction mechanism is reasonable and the structure is clear. For example, the rotation drive mechanism realizes the rotation of the earth-sealing frame through the cooperation of the gear disk and the drive device. This design is simple and efficient. The simple structure not only reduces the manufacturing cost of the equipment, but also in actual use, the smaller volume enables the device to have better operating flexibility in a site with limited space, and reduces the maintenance difficulty and maintenance cost of the equipment.

[0025] Furthermore, the soil-covering frame of the present invention includes a rotating plate and a soil-covering scraper. A recessed portion is provided on one side of the rotating plate close to the axis of the support frame. The soil-covering scraper is fixedly connected to the inner wall of the recessed portion and is partially located below the rotating plate. In the process of the rotary drive mechanism driving the soil-covering frame to rotate, the soil-covering scraper can effectively scrape up the soil and transport it to the area where soil covering is required. Through reasonable structural design and rotation method, the backfill volume is increased, which can meet the requirements of various actual soil-covering operation scenarios such as soil improvement, vegetation planting, and site leveling, improve the operation effect, and provide a guarantee for the smooth development of subsequent work.

[0026] Furthermore, the support frame includes a top plate, a bottom plate and a plurality of outer plates, the top plate and the bottom plate are both open ring-shaped and equal in size, one end of each outer plate is fixedly connected to the top plate and the other end is fixedly connected to the bottom plate, and all the outer plates constitute the side plates of the support frame. This structural design enables the support frame to have good stability and load-bearing capacity, and can stably support the entire rotary soil covering and compacting device, ensuring the normal operation of each component during the working process. At the same time, the open ring-shaped top plate and bottom plate design facilitate the passage of plants that need to be covered with soil at their roots, meeting the actual operation needs.

[0027] Furthermore, the rotary drive mechanism includes a toothed disc and at least one driving device, the driving device is fixed on the support frame, and a driving gear meshing with the toothed disc is fixed on its output shaft, the toothed disc is in an open ring shape and is fixedly connected to the rotating plate, and the toothed disc rotates in coordination with the support frame. This design can accurately control the rotation of the earth-covering frame, and the driving gear is driven to rotate by the driving device, thereby driving the toothed disc to rotate, thereby realizing the circumferential rotation of the earth-covering frame, and providing power support for the earth-covering operation. In addition, a plurality of first support seats are provided on the top surface of the toothed disc, each of which is equipped with a first roller, and the first roller and the top plate roll in coordination along the circumference of the support frame; a plurality of second support seats are provided on the inner wall of the side plate, each of which is equipped with a second roller, and the second roller and the toothed disc roll in coordination along the circumference of the support frame; the teeth of the toothed disc are located on the outer ring of the toothed disc, and a plurality of third support seats are provided on the support frame, each of which is equipped with a third roller, and the third roller and the inner ring of the toothed disc roll in coordination along the circumference of the support frame. The setting of these rollers, on the one hand, reduces the friction between the toothed disc and the support frame, making the toothed disc rotate more smoothly and reducing energy loss; on the other hand, it improves the stability and accuracy of the toothed disc rotation, ensures the stability of the covering soil frame during rotation, and is conducive to improving the quality of the covering operation.

[0028] Furthermore, when there are two driving devices and they are spaced apart along the circumference of the support frame, a more uniform and stable driving force can be provided, so that the gear disc rotates more smoothly, and the unstable rotation of the soil covering frame caused by uneven driving force can be avoided. This design further improves the efficiency and quality of soil covering operations, ensuring that the soil covering scraper can evenly scrape the soil and transport it to the designated area.

[0029] Furthermore, the compaction drive mechanism adopts a hydraulic cylinder, which has the advantages of large output force, smooth movement, and fast response speed. In this device, the hydraulic cylinder can provide sufficient pressure for the compaction plate to ensure that the compaction plate can effectively compact the covering soil. In addition, by controlling the extension and contraction of the hydraulic cylinder, the reciprocating linear motion of the compaction plate can be accurately controlled to meet the requirements of different covering soil thickness and compaction degree, thereby improving the quality and adaptability of the compaction operation.

[0030] Furthermore, the direction of the reciprocating motion of the compacting plate is an inclined direction. This design enables the compacting plate to exert an oblique force on the soil during the compacting process, which not only compacts the soil, but also stirs and mixes the soil to a certain extent, making the soil more uniform and conducive to plant growth. At the same time, the inclined motion direction can increase the contact area and contact time between the compacting plate and the soil, thereby improving the compaction effect.

[0031] Furthermore, the compaction mechanism is located on one side of the rotating plate close to the axis of the support frame. This position design enables the compaction mechanism to compact the covering soil in time after the covering frame completes the covering soil. After the covering scraper scrapes the soil to the area where the covering soil is required, the compaction mechanism located at this position can immediately compact the covering soil, ensuring the continuity and efficiency of the covering soil operation and improving the working efficiency of the entire device.

[0032] Furthermore, a connecting plate is fixed on the support frame, and the connecting plate is used to connect with the output end of the lifting drive mechanism. Through the setting of the connecting plate, a reliable connection between the lifting drive mechanism and the support frame is achieved, and the lifting drive force can be accurately transmitted, so that the support frame can perform lifting movement according to predetermined requirements, providing necessary support for the normal operation of the entire rotary soil covering and compacting device.

The soil sealing scraper 29 is fixedly connected to the inner wall of the concave portion, and a part of the soil sealing scraper 29 is located below the rotating plate 23.

[0044] A rotary drive mechanism, which is used to drive the earth-sealing frame to rotate along the circumferential direction of the support frame 10;

[0045] The compaction mechanism includes a connecting frame 24 fixedly connected to the rotating plate 23, a compaction drive mechanism fixedly connected to the connecting frame 24, and a compaction plate 25 fixedly connected to the output end of the compaction drive mechanism. The compaction drive mechanism is used to drive the compaction plate 25 to perform reciprocating linear motion to compact the covering soil.

[0046] During the process of the rotary drive mechanism driving the soil covering frame to rotate, the soil covering scraper 29 can effectively scrape up the soil and transport it to the area where soil covering is required. Through reasonable structural design and rotation method, the backfill volume is increased, which can meet the needs of various actual soil covering operation scenarios such as soil improvement, vegetation planting, site leveling, etc., improve the operation effect, and provide a guarantee for the smooth progress of subsequent work.

[0047] In the optional scheme of the present embodiment, it is more preferred that the support frame 10 includes a top plate 11, a bottom plate 13 and multiple outer plates 12, the top plate 11 and the bottom plate 13 are both open ring-shaped and equal in size, and each outer plate 12 is fixedly connected to the top plate 11 at one end and to the bottom plate 13 at the other end; all the outer plates 12 constitute the side plates of the support frame 10; this structural design enables the support frame 10 to have good stability and bearing capacity, and can stably support the entire rotary soil covering and compacting device to ensure the normal operation of each component during operation. At the same time, the open ring-shaped top plate 11 and the bottom plate 13 design facilitate the passage of plants that need to be covered with soil at the roots, meeting actual operation needs.

[0048] In the optional scheme of this embodiment, it is more preferred that the rotary drive mechanism includes a toothed disc 22 and at least one driving device 21, the driving device 21 is fixedly mounted on the support frame 10, and a driving gear meshing with the toothed disc 22 is fixedly mounted on the output shaft of the driving device 21, the toothed disc 22 is in the shape of an open ring, and the opening of the toothed disc 22 is used for plants that need to be covered with soil at their roots to pass through, and the rotating plate 23 is fixedly connected to the toothed disc 22; the toothed disc 22 rotates in coordination with the support frame 10; the rotary drive mechanism can accurately control the rotation of the soil covering frame, and the driving gear is driven to rotate by the driving device 21, thereby driving the toothed disc 22 to rotate, thereby realizing the circumferential rotation of the soil covering frame, and providing power support for the soil covering operation.

[0049] The specific scheme of the rotational cooperation between the toothed disc 22 and the support frame 10 is as follows:

[0050] A plurality of first support seats are provided on the top surface of the toothed disc 22, and a first roller 26 is installed on each of the first support seats, and the first roller 26 and the top plate 11 are rollingly matched along the circumference of the support frame 10; a plurality of second support seats are provided on the inner wall of the side plate, and a second roller 27 is installed on each of the second support seats, and the second roller 27 and the toothed disc 22 are rollingly matched along the circumference of the support frame 10; the teeth of the toothed disc 22 are located on the outer ring of the toothed disc 22; a plurality of third support seats are provided on the support frame 10, and a third roller 28 is installed on each of the third support seats, and the third roller 28 and the inner ring of the toothed disc 22 are rollingly matched along the circumference of the support frame 10;

[0051] The provision of the first roller 26, the second roller 27 and the third roller 28, on the one hand, reduces the friction between the toothed disc 22 and the support frame 10, making the rotation of the toothed disc 22 smoother and reducing energy loss; on the other hand, it improves the stability and accuracy of the rotation of the toothed disc 22, ensures the stability of the earth-covering frame during rotation, and is conducive to improving the quality of the earth-covering operation.

[0052] In the optional scheme of this embodiment, it is more preferred that there are two driving devices 21, and the two driving devices 21 are spaced apart along the circumference of the support frame 10, which can provide a more uniform and stable driving force, so that the toothed disc 22 rotates more smoothly, and avoids the unstable rotation of the soil-covering frame caused by uneven driving force. This design further improves the efficiency and quality of the soil-covering operation, ensuring that the soil-covering scraper 29 can evenly scrape the soil and transport it to the designated area.

[0053] In the optional scheme of this embodiment, it is more preferred that the compaction drive mechanism adopts a hydraulic cylinder; the hydraulic cylinder can provide sufficient pressure for the compaction plate 25 to ensure that the compaction plate 25 can effectively compact the covering soil. In addition, by controlling the extension and contraction of the hydraulic cylinder, the reciprocating linear motion of the compaction plate 25 can be accurately controlled to meet the requirements of different covering soil thicknesses and compaction degrees, thereby improving the quality and adaptability of the compaction operation; however, in actual applications, the compaction drive mechanism can also adopt other forms of drive equipment such as linear motors.

[0054] In the optional scheme of this embodiment, it is more preferred that the direction of the reciprocating motion of the compacting plate 25 is an inclined direction; this design enables the compacting plate 25 to generate an oblique force on the soil during the process of compacting the covering soil, which can not only compact the soil, but also stir and mix the soil to a certain extent, making the soil more uniform and conducive to the growth of plants. At the same time, the inclined motion direction can increase the contact area and contact time between the compacting plate 25 and the soil, thereby improving the compaction effect.

[0055] In the optional scheme of this embodiment, it is more preferred that the compaction mechanism is located on the side of the rotating plate 23 close to the axis of the support frame 10; such a position design enables the compaction mechanism to compact the covering soil in time after the covering soil frame completes the covering soil. After the covering soil scraper 29 scrapes the soil to the area where the covering soil is required, the compaction mechanism located at this position can immediately compact the covering soil, thereby ensuring the continuity and efficiency of the covering soil operation and improving the working efficiency of the entire device.

[0056] In the optional scheme of this embodiment, it is more preferred that a connecting plate 20 is fixedly provided on the support frame 10, and the connecting plate 20 is used to connect with the output end of the lifting drive mechanism. Through the setting of the connecting plate 20, a reliable connection between the lifting drive mechanism and the support frame 10 is achieved, and the lifting drive force can be accurately transmitted, so that the support frame 10 can perform lifting movement according to predetermined requirements, providing necessary support for the normal operation of the entire rotary soil covering and compacting device.

[0057] It should be noted that agricultural machinery equipment with a hydraulic lifting mechanism can be used as the lifting drive mechanism in this embodiment, such as a tractor, a ridge builder, a wheat press, and a hiller.

[0058] The specific method of using the rotary soil covering and compacting device of this embodiment is as follows:

[0059] ① Move the rotary soil covering and compacting device of this embodiment to the location of the plant that needs to be covered with soil at the root, align the opening of the support frame 10 with the plant, and prepare for the subsequent soil covering operation; at this time, the connecting plate 20 on the support frame 10 is connected to the output end of the lifting drive mechanism to ensure that the device can be accurately controlled in the vertical direction;

[0060] ② The lifting drive mechanism starts to work, and drives the support frame 10 to perform lifting movement by converting and transmitting hydraulic, electric or other forms of power; according to the actual needs of the plants and the operation requirements, the height of the support frame 10 is adjusted so that the soil covering frame can be in a suitable soil covering position; this step provides the necessary height adjustment function for the subsequent soil covering operation, ensuring that the soil covering frame can accurately contact the area that needs to be covered with soil;

[0061] ③ The rotary drive mechanism is started to drive the soil-covering frame to rotate along the circumferential direction of the support frame 10; specifically, the driving device 21 (such as a motor) drives the driving gear on the output shaft to rotate, and the driving gear meshes with the toothed disc 22, thereby driving the toothed disc 22 to rotate. Since the rotating plate 23 is fixedly connected to the toothed disc 22, the rotation of the soil-covering frame is realized; during the rotation process, the soil-covering scraper 29 of the soil-covering frame plays a role; the recessed portion of the rotating plate 23 close to the axis of the support frame 10 provides an installation position for the soil-covering scraper 29. During the rotation process, the soil-covering scraper 29 can scrape up the surrounding soil (i.e., the soil dug out from the pit for planting plants), and cover the soil around the roots of the plants as it rotates, completing the soil-covering action; this rotary soil-covering method can cover the soil on the roots of the plants more evenly, thereby improving the quality and efficiency of soil-covering;

[0062] ④ After the soil-covering frame is covered with soil, the compaction mechanism starts to work; the compaction mechanism includes a connecting frame 24 fixedly connected to the rotating plate 23, and the connecting frame 24 connects the compaction drive mechanism and the rotating plate 23 as a whole, ensuring that the compaction mechanism can move synchronously with the rotation of the rotating plate 23. After the rotating plate 23 rotates a preset angle, the compaction drive mechanism can perform a preset number of compaction operations; the compaction drive mechanism (such as a hydraulic cylinder) drives the compaction plate 25 to perform reciprocating linear motion; when the compaction plate 25 moves to contact with the covering soil, a certain pressure is applied, The soil covering the roots of the plants is compacted; the direction of the reciprocating motion of the compacting plate 25 is an inclined direction. This design can not only compact the soil, but also stir and mix the soil to a certain extent, making the soil more uniform, which is conducive to the growth of plants; at the same time, the inclined motion direction can increase the contact area and contact time between the compacting plate 25 and the soil, further improving the compaction effect; since the compaction mechanism is located on the side of the rotating plate 23 close to the axis of the support frame 10, the covering soil can be compacted in time after covering the soil, ensuring the continuity and efficiency of the covering operation;

[0063] ⑤ After completing the soil covering and compacting operation on the plant roots, the lifting drive mechanism works again to lift the support frame 10 and make the device leave the working area; then, the rotating drive mechanism stops working, the soil covering frame stops rotating, and the entire device returns to its initial state, ready for the next operation.

[0064] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
