Description

Technical Field

[0001] This utility model relates to the field of peanut harvester technology, and in particular to a peanut digging shovel used in peanut harvesters. Background Technology

[0002] As an important economic crop, the level of mechanization in the peanut harvesting process directly affects production efficiency. The performance of the digging shovel, one of the core components of a peanut harvester, directly determines the quality and efficiency of the harvesting operation.

[0003] Currently, existing technologies commonly use fixed or vibratory shovels. While these technologies are structurally mature, they still have certain shortcomings in practical applications. For example, traditional digging shovels typically have fixed widths and spacing, making it impossible to flexibly adjust them according to different peanut ridging specifications. This means that when working in fields with inconsistent ridge widths, shovels that are too wide can collapse the ridge shoulders and damage the peanut plants, while shovels that are too narrow can cause peanut pods on the sides of the ridge to be missed, resulting in harvest losses.

[0004] Therefore, this application provides a peanut digging shovel for use in peanut harvesters to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a peanut digging shovel for use in peanut harvesters, so as to solve the problem that the existing digging shovels, due to their fixed shovel width and spacing, cannot adapt to different ridging specifications, resulting in easy damage to the ridges or missed harvesting during operation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A peanut digging shovel for use in a peanut harvester includes a base column. A connecting seat for connecting the peanut harvester is fixed in the middle of the base column. At least two shovel bodies are symmetrically mounted on the connecting seat. A central column is fixed in the middle of each shovel body. A fixed seat is connected to the top of the central column. A limiting claw for locking onto the base column is fixed to the top of the fixed seat. The middle of the base column is hollow and has a horizontally movable rod. Multiple connecting rods are symmetrically hinged to the upper and lower sides of the movable rod. The connecting rods on both sides are respectively movably connected to positioning columns that vertically extend out of the upper and lower surfaces of the base column. The positioning columns vertically penetrate the limiting claws.

[0008] Optionally, the limiting claw slides horizontally onto the base column.

[0009] Optionally, one end of the movable rod extends beyond the end side of the base column and is provided with a pull ring.

[0010] Optionally, a positioning bolt is provided at one end of the movable rod extending from the side of the base column, and the positioning bolt is threadedly inserted and fixed to the outer side wall of the base column.

[0011] Optionally, the front bottom of the shovel body is provided with a detachable shovel tip.

[0012] Optionally, a mounting groove is provided on the lower front side of the central column, and a positioning block is fixed to the top of the shovel tip, which is horizontally inserted into the mounting groove.

[0013] Optionally, the lower end of the central column is vertically inserted with a fastening bolt for securing the shovel tip.

[0014] Optionally, the fastening bolt is threaded into the mounting groove and vertically passes through the middle of the positioning block.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, through the linkage of the movable rod, connecting rod and positioning column, the locking and releasing of all shovels can be controlled synchronously with a single operation, realizing stepless and convenient adjustment of the shovel spacing, enabling the digging shovels to accurately adapt to different ridging specifications, effectively avoiding ridge damage and missed harvesting, and significantly improving the adaptability of the harvester.

[0017] In the above solution, the combination of positioning blocks, mounting slots and vertically set fastening bolts enables quick disassembly and assembly of the shovel tip. When the shovel tip wears out, it is not necessary to replace the entire shovel body or weld it. Replacement can be completed by simply tightening a single bolt, which greatly reduces maintenance costs and time and ensures the continuity of operation.

It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings.

[0032] like Figures 1 to 4 As shown, an embodiment of this utility model provides a peanut digging shovel for use in a peanut harvester, including a base column 1 as the main load-bearing beam. The base column 1 preferably adopts a hollow square tube structure to balance lightweight and structural strength. A connecting seat 2 is fixed in the middle of the base column 1. The connecting seat 2 is provided with standard mounting holes for securely installing the entire digging shovel assembly onto the suspension mechanism of the peanut harvester by bolts.

[0033] To adjust the working width, at least two shovels 3 are symmetrically installed on the base column 1. In other embodiments, three or four shovels may be installed to accommodate multi-row harvesting. A central column 301 is vertically fixed to the center of each shovel 3. A fixing seat 4 is connected to the top of the central column 301. At least one pair of limiting claws 401 are integrally cast or welded to the top of the fixing seat 4. The shape of the limiting claws 401 matches the outer contour of the base column 1, allowing them to slide horizontally onto the base column 1, similar to a "slider". This allows the shovels 3 to move freely along the axial direction of the base column 1 to adjust the spacing between adjacent shovels 3.

[0034] A horizontally movable rod 5 is installed within the hollow cavity of the base column 1. Multiple connecting rods 502 are symmetrically hinged to the upper and lower sides of this movable rod 5, appearing in pairs. Through holes are provided on the upper and lower walls of the base column 1, corresponding to the fixing seats 4 of each shovel body 3, allowing the positioning pins 6 to extend vertically beyond the upper and lower surfaces of the base column 1. The lower ends of these positioning pins 6 are movably connected to the free ends of the connecting rods 502 via pins, while their upper ends can vertically penetrate the corresponding through holes on the limiting claws 401. When it is necessary to adjust the spacing between the shovel bodies 3, the operator first pulls the movable rod 5 outwards. The movable rod 5, through the connecting rods 502, causes all the positioning pins 6 to retract into the base column 1, releasing the locking of the shovel bodies 3. At this time, all shovels 3 can slide on the base column 1. After each shovel 3 is adjusted to the ideal position that matches the peanut row spacing, the movable rod 5 can be pushed inward to reset. The movable rod 5 will then drive all the positioning columns 6 to move outward from the base column 1 through the transmission of the connecting rod 502, so that they can be accurately inserted into the through holes of their respective limiting claws 401, thereby firmly locking all the shovels 3 on the base column 1, thus realizing the synchronous locking and releasing of all the shovels 3.

[0035] In practice, to further ensure the reliability of locking, a positioning bolt 501 is provided at one end of the movable rod 5 that extends out of the side of the base column 1. When the movable rod 5 is in the locked position, the positioning bolt 501 is tightened so that its end is pressed against the outer wall of the base column 1, which can effectively prevent the movable rod 5 from moving accidentally under vibration conditions.

[0036] In addition, to address the issue of easy wear on the shovel tip in existing technologies, this device provides a detachable shovel tip 7 at the bottom front end of each shovel body 3. Specifically, a mounting groove 302 is provided on the lower front side of the central column 301, and a positioning block 701, matching the shape of the mounting groove 302, is fixed to the top of the shovel tip 7. For replacement, simply insert the positioning block 701 of the shovel tip 7 horizontally into the mounting groove 302 to complete initial positioning and support. To provide a strong fastening force, a fastening bolt 8 is vertically inserted into the lower end of the central column 301. This fastening bolt 8 is threaded from top to bottom into the threaded hole at the top of the mounting groove 302, and finally vertically passes through the pre-set light hole in the middle of the positioning block 701, achieving quick and secure installation of the shovel tip 7.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] In actual use, when the working width needs to be adjusted, the operator first loosens the positioning bolt 501 and then pulls the movable rod 5 outward. The movable rod 5 moves horizontally inside the base column 1, driving all the positioning columns 6 to move downward synchronously through the hinged connecting rod 502, causing their tops to exit from the corresponding holes of the limiting claws 401. At this time, all the shovels 3 are in the unlocked state and can slide freely along the base column 1 to a position that matches the peanut ridge spacing. After adjustment, the movable rod 5 is pushed inward, and through the transmission of the connecting rod 502, all the positioning columns 6 rise synchronously and are precisely inserted into their respective limiting claw 401 holes. Finally, the positioning bolt 501 is tightened to press against the outer wall of the base column 1, thus completing the synchronous locking of all the shovels 3.

[0039] Meanwhile, this device features an independently detachable shovel tip 7 at the bottom front end of each shovel body 3. Specifically, a mounting groove 302 is provided on the front side of the lower end of the central column 301, and correspondingly, a positioning block 701 that can be horizontally embedded in the mounting groove 302 is fixed on the top of the shovel tip 7. Therefore, in actual maintenance operations, when the shovel tip 7 is worn and needs to be replaced, the operator only needs to use a tool to unscrew the fastening bolt 8 to horizontally remove the old shovel tip 7 from the mounting groove 302. Then, the positioning block 701 of the new shovel tip 7 is aligned with the mounting groove 302 and pushed horizontally in, then vertically inserted and tightened with the fastening bolt 8 so that it passes through the middle of the positioning block 701, thus forming a fixed position.

[0040] In summary, this device achieves flexible adjustment of the shovel body spacing through the linkage mechanism of movable rod 5, connecting rod 502 and positioning column 6. At the same time, the quick replacement of the shovel tip is achieved through the cooperation of positioning block 701 and fastening bolt 8. Overall, the device has good performance.

[0041] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
