Description

Technical Field

[0001] This invention relates to an agricultural machinery device, and more specifically to a modular chassis for a kenaf harvester. Background Technology

[0002] Rugby is an annual or perennial herbaceous plant belonging to the Malvaceae family and the Hibiscus genus. Its stems are straight, reaching approximately 3 meters in height and 2 centimeters in diameter. Rugby is widely cultivated, and for small-scale growers who may also cultivate other crops in their fields, a single dedicated rugby harvester is not cost-effective. Therefore, a rugby harvester that can also harvest other crops is needed. Since the structures for cutting, collecting, and baling vary depending on the crop, a better solution is to replace these different structures while retaining the universally compatible harvester body and the chassis for assembly. This invention aims to design an interlocking chassis for use in rugby harvesters, enabling the assembly and use of different processing units. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a modular chassis for a kenaf harvester. Through a modular frame structure design, it facilitates rapid assembly and disassembly of the structure. Processing units can be assembled as needed for harvesting different crops, and the main body of the kenaf harvester can be used as a universal component, greatly reducing the mechanical costs of harvesting different crops.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a splicing chassis for a ramie harvester, comprising a base frame, a connecting frame hinged to one side of the base frame, and a locking hole at the far end of the connecting frame for fitting from top to bottom onto corresponding locking posts on the side of the ramie harvester body; wheels for supporting the base frame for movement at the lower part of the base frame; the base frame is formed by connecting several horizontal and vertical bars to form several square mounting outer frames, and different processing units are installed on the upper part of the base frame, the processing units being set in splicing units, and the splicing units being installed correspondingly to the mounting outer frames; the splicing unit includes a square base frame and an inner mounting frame set at the lower part of the square base frame, the outer perimeter of the inner mounting frame matching the inner perimeter of the outer mounting frame for corresponding fitting, the square base frame supporting the upper part of the outer mounting frame, and horizontally penetrating mounting holes on the horizontal and vertical bars forming the outer mounting frame, and horizontally penetrating waist-shaped holes on the inner mounting frame corresponding to the mounting holes, the structure being locked by installing fasteners at the corresponding mounting holes and waist-shaped holes.

[0005] As an improvement, each horizontal and vertical bar that makes up the outer frame of the mounting frame is provided with 2-3 mounting holes at intervals, and the waist-shaped holes on the inner frame of the mounting frame are provided in corresponding positions to the mounting holes.

[0006] As an improvement, a deformable support pad is provided at the bottom of the square base frame. When the square base frame is supported on the upper part of the mounting outer frame, the support pad deforms and compresses.

[0007] As an improvement, the splicing unit also includes a vertical frame and an upper frame. The lower end of the vertical frame is located at the four corners of the square base frame, and the upper end is connected to the four corners of the upper frame, thus forming a cubic space in which the processing unit is housed. The vertical frame has a horizontally penetrating, vertically oriented waist-shaped hole, and adjacent splicing units are locked to each other by fasteners passing through the waist-shaped hole on the vertical frame.

[0008] As an improvement, the waist-shaped holes on the vertical frame are spaced 2-3 times apart along the length of the vertical frame.

[0009] As an improvement, the splicing unit also includes an elastic mating block, which is set between adjacent vertical frames. The elastic mating block is provided with through holes for fasteners to pass through. The elastic mating block is locked between adjacent vertical frames by deformation interference fit, and the through holes correspond to the waist-shaped holes of the adjacent vertical frames for fastener installation.

[0010] As an improvement, the connecting frame is configured with two sets, one in front and one behind, on one side of the base frame.

[0011] As an improvement, the locking pin is set to be hemispherical, and the inner diameter of the locking hole is adapted to the maximum outer diameter of the locking pin. When the locking hole is fitted into the locking pin, the bottom end of the locking hole is located at the maximum outer diameter of the locking pin, and the connecting frame remains horizontal.

[0012] As an improvement, the main body of the ramie harvester is equipped with elastic pads around the outer perimeter of the clamping posts, and the connecting frame is placed on the elastic pads for elastic support.

[0013] The beneficial effects of this invention are:

[0014] 1. The connecting frame allows the base frame and the harvester body to be separated, thus enabling flexible adjustment of the base frame specifications. This allows for flexible selection of base frames with different numbers of external frames to be assembled with the harvester body, meeting the harvesting needs of different crops.

[0015] 2. The frame-type base and the upper splicing unit are used together for flexible assembly and use. Different functional processing units can be assembled in a compatible manner, and can be used for harvesting and processing operations of different crops.

[0016] 3. The outer frame and splicing units are assembled stably using a standard square structure, and multi-position locking is achieved using a hole structure to ensure structural stability. Attached Figure Description

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 , 2 Figures 3 and 4 show specific embodiments of the spliced ​​chassis of the ramie harvester of the present invention. The figures only illustrate the mutual cooperation between the structures. The position and size ratio of the specific structures can be reasonably adjusted according to the actual product situation, and do not limit the scope of protection of the present invention.

[0023] The specific embodiment includes a base frame 1, with a connecting frame 3 hinged to one side of the base frame 1. The far end of the connecting frame 3 has a locking hole 31, which is used to fit from top to bottom onto the corresponding locking post 0 on the side of the main body of the ramie harvester. Wheels 4 are provided at the lower part of the base frame 1 to support its movement. The base frame 1 is formed by connecting several horizontal bars 11 and vertical bars 12 to create several square mounting frames 2. Different processing units are installed on the upper part of the base frame 1. The processing units are located in splicing units 5, which are installed correspondingly to the mounting frames 2. The connecting unit 5 includes a square base frame 51 and an inner mounting frame 52 disposed at the lower part of the square base frame 51. The outer dimensions of the inner mounting frame 52 match the inner dimensions of the outer mounting frame 2 for corresponding fitting. The square base frame 51 is supported on the upper part of the outer mounting frame 2. The horizontal bars 11 and vertical bars 12 that make up the outer mounting frame 2 are provided with horizontally penetrating mounting holes 21. The inner mounting frame 52 is provided with horizontally penetrating horizontally penetrating waist-shaped holes 521 at the corresponding mounting holes 21. The structure is locked by installing fasteners 6 at the corresponding mounting holes 21 and waist-shaped holes 521.

[0024] In use, the main body of the kenaf harvester can be a conventional harvester vehicle capable of traversing fields, with a locking post 0 added to one side for detachable connection to the connecting frame 3. The base frame 1 is configured with the required number of square mounting frames 2, depending on the size or number of processing units needed for the crop to be harvested. Figure 1For example, the processing unit requires a 2*4 mounting outer frame 2. Therefore, a 2*4 mounting outer frame 2 is selected, and a hinged connecting frame 3 is connected to the locking post 0 on the main body of the harvester. Specifically, the locking hole 31 on the connecting frame 3 is adapted to fit the locking post 0. The wheels 4 below the base frame 1 allow the base frame 1 to move along with the harvester. Depending on its size and space requirements, the processing unit can be housed in one or more splicing units 5. The mounting inner frame 52 at the bottom of the splicing unit 5 is fitted into the mounting outer frame 2 formed by the horizontal bar 11 and the vertical bar 12. Then, the square base frame 51 is supported on the upper part of the mounting outer frame 2. To avoid slight displacement of the installation position due to excessive structure size, the hole structure for fastener 6 connection is set as mounting holes 21 for accurate positioning, located on the horizontal bar 11 and the vertical bar 12, and waist-shaped holes 521 for ignoring errors, located on the mounting inner frame 52. Figure 2 As shown, after the inner frame 52 is fitted into the outer frame 2, the waist-shaped hole 521 corresponds to the mounting hole 21. The lateral width of the waist-shaped hole 521 can ignore the lateral error of the inner frame 52. The four sides can be easily installed and fixed by fasteners 6, such as bolts and nuts, so that the splicing unit 5 and the base frame 1 become a solid integrated structure. Each processing unit can be used after subsequent connection on the base frame 1. When it is necessary to replace the processing unit, the disassembly of the splicing unit 5 and the base frame 1 is also relatively simple, and the function can be replaced. It is applicable to some small-area cultivation and has a better cost performance when dealing with the automated and mechanized harvesting of different crops.

[0025] As an improved specific implementation, each horizontal bar 11 and vertical bar 12 of the outer frame 2 is provided with 2-3 mounting holes 21 at intervals, and the waist-shaped holes 521 on the inner frame 52 are provided in correspondence with the mounting holes 21.

[0026] like Figure 2 As shown, 2-3 mounting holes 21 are provided to lock the structure at multiple positions, thereby improving the strength and stability of the assembly between structures; and an appropriate number of locking positions will not excessively increase the cumbersomeness of disassembly and assembly, thus achieving a balance between stability and operational difficulty.

[0027] As an improved specific implementation, a deformable support pad 511 is provided at the lower part of the square base frame 51. When the square base frame 51 is supported on the upper part of the mounting outer frame 2, the support pad 511 is deformed and compressed.

[0028] like Figure 2As shown, when the square base frame 51 is supported on the upper part of the mounting outer frame 2, the splicing unit 5 also houses the processing unit, resulting in a relatively heavy overall weight. This significantly compresses the support pad 511, ensuring full contact and support between the square base frame 51 and the mounting outer frame 2. After locking the square base frame 51 and the mounting outer frame 2, there is no possibility of the square base frame 51 vibrating, resulting in good overall integrity and ensuring the stability of the processing unit's arrangement. The support pad 511 can be replaced with a new one during the next assembly, thus maintaining its physical properties.

[0029] As an improved specific implementation, the splicing unit 5 also includes a vertical frame 53 and an upper frame 54. The lower end of the vertical frame 53 is located at the four corners of the square base frame 51, and the upper end is connected to the four corners of the upper frame 54, thereby forming a cubic space in which the processing unit is accommodated. A vertically placed waist-shaped hole 521 is horizontally provided on the vertical frame 53, and adjacent splicing units 5 are locked to each other by fasteners 6 passing through the waist-shaped hole 521 on the vertical frame 53.

[0030] like Figure 2 , 3 As shown, the square upper frame 54, the four vertical frames 53, and the square bottom frame 51 enclose a cubic storage space, which can be used to house processing units. For larger processing units, multiple splicing units 5 can be used to accommodate them. The middle part of the side of the splicing unit 5 is hollowed out to facilitate the arrangement and docking of processing units. Adjacent vertical frames 53 are provided with waist-shaped holes 521 and are locked to each other by fasteners 6, which can further improve the strength and stability between structures.

[0031] As an improved specific implementation, the waist-shaped holes 521 on the vertical frame 53 are arranged at intervals of 2-3 along the length direction of the vertical frame 53.

[0032] like Figure 2 As shown, 2-3 mounting holes 21 are provided in the length direction, i.e. the height direction, so that the structure can be locked at multiple positions at the height, thereby improving the strength and stability of the assembly between structures; and an appropriate number of locking positions will not excessively increase the cumbersomeness of disassembly and assembly, thus achieving a balance between stability and operational difficulty.

[0033] As an improved specific implementation, the splicing unit 5 also includes an elastic mating block 55. The elastic mating block 55 is disposed between adjacent vertical frames 53. The elastic mating block 55 is provided with a through hole 551 for fasteners 6 to pass through. The elastic mating block 55 is locked between adjacent vertical frames 53 by deformation interference fit, and the through hole 551 corresponds to the waist-shaped hole 521 of the adjacent vertical frame 53 for fasteners 6 to be installed.

[0034] like Figure 3As shown, the gap between splicing units 5 may cause instability between structures. The further provided elastic mating block 55 provides abutment and limit between adjacent vertical frames 53, so that adjacent vertical frames 53 form mutual support and restraint in structure, thereby enhancing the overall strength and stability. The elastic mating block 55 is installed at the position of the waist-shaped hole 521 and is installed by fastener 6 passing through the through hole 551. The size of the elastic mating block 55 can be slightly larger than the distance between adjacent vertical frames 53. By slightly deforming and locking between adjacent vertical frames 53, the structure achieves tight contact and stability.

[0035] As an improved specific implementation, the connecting frame 3 is configured as two sets, one in front and one behind, on one side of the base frame 1.

[0036] like Figure 1 As shown, the front and rear connecting frames 3 are adapted to longer harvesters and the base frame 1, so as to achieve stable connection between the front and rear structures.

[0037] As an improved specific implementation, the locking post 0 is set as a hemispherical shape, and the inner diameter of the locking hole 31 is adapted to the maximum outer diameter of the locking post 0. When the locking hole 31 is fitted into the locking post 0, the bottom end of the locking hole 31 is located at the maximum outer diameter of the locking post 0, and the connecting frame 3 remains in a horizontal state.

[0038] like Figure 4 As shown, the locking hole 31 is fitted onto the locking post 0. At this time, the connecting frame 3 remains horizontal, that is, the base frame 1 is supported on the ground by the wheel body 4 and remains horizontal, so that the processing unit on it can work in a nearly horizontal state. On the other hand, the locking post 0 is set as a hemispherical shape, so that when the harvester and the base frame 1 move, the connecting frame 3 has a certain degree of swing flexibility after the locking hole 31 is fitted onto it. While ensuring that the locking post 0 and the locking hole 31 do not separate, this swing flexibility can adapt to the unevenness of the field surface and reduce the structural wear caused by the rigid limit between the locking post 0 and the locking hole 31.

[0039] As an improved specific implementation, the main body of the ramie harvester is provided with an elastic pad 01 around the outer periphery of the locking post 0, and the connecting frame 3 is placed on the elastic pad 01 for elastic support.

[0040] like Figure 4 As shown, the elastic pad 01 allows the connecting frame 3 to buffer the structure when it swings with the main body, avoiding hard impacts, thereby reducing structural wear and extending service life.

[0041] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
