Description

Technical Field

[0001] This invention relates to the field of harvester technology, and specifically to a pickled mustard tuber harvester. Background Technology

[0002] Pickled mustard tuber, a variety of mustard greens belonging to the Brassicaceae family, is also known as green mustard tuber, stem mustard, water chestnut vegetable, and goat horn vegetable. It consists of leaves, fleshy stems, and roots. Because its fleshy stems can be processed and pickled to make pickled mustard tuber, it is widely cultivated in Sichuan, Chongqing, Hunan, and other places.

[0003] Traditionally, pickled mustard tubers are harvested manually with a knife, which is inefficient. With technological advancements, pickled mustard tuber harvesters (also called pickled mustard tuber combine harvesters) have emerged. For example, Chinese patents with application numbers CN201410218522.9 and 201510405088.X both provide a pickled mustard tuber harvester. However, these harvesters are only suitable for plains and large-scale planting, and cannot be used in complex terrains such as mountains and hills, or for small-scale planting. Summary of the Invention

[0010] Furthermore, the first end of the second cutting blade is hinged to the second mounting base, and the second end is capable of reciprocating between a third position and a fourth position around its own hinge center line.

[0025] like Figure 1-5As shown, the present invention provides a pickled mustard tuber harvester, including a frame 100, a first cutting component, a second cutting component, and a drive component.

[0026] The frame 100 has a handle 110 at its first end. A first cutting assembly, a second cutting assembly, and a drive assembly are located at the second end of the frame 100, with the second cutting assembly positioned below the first cutting assembly. The first cutting assembly cuts the leaves of the pickled mustard tuber to separate the leaves from the fleshy stem. The second cutting assembly cuts the root of the pickled mustard tuber to separate the fleshy stem from the root. The drive assembly is connected to both the first and second cutting assemblies to transmit power, enabling them to perform cutting operations.

[0027] During operation, the pickled mustard tuber harvester is placed in the preset position by using the handle, and the drive component is started. The drive component drives the first and second cutting components to run, thereby achieving the purpose of automatically separating the leaves, fleshy stems and roots of the pickled mustard tuber, improving efficiency. It is also simple, small and compact in structure, and suitable for complex terrains such as mountainous areas and hilly areas and small-area planting.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the first cutting assembly includes a first mounting base 210, a mounting arm 220, and a first cutting blade 230.

[0029] A first mounting base 210 is rotatably mounted on the frame 100 so that it can rotate about its own rotation center line, which extends longitudinally. A mounting arm 220 is eccentrically disposed on the side of the first mounting base 210 facing the second cutting assembly. A first end of the mounting arm 220 is fixedly connected to the first mounting base 210, and a second end extends toward the second cutting assembly. A first cutting blade 230 is disposed at the second end of the mounting arm 220. A first end of the first cutting blade 230 is connected to the mounting arm 220, and a second end extends toward the rotation center line of the first mounting base 210. A drive assembly is used to drive the first mounting base 210 to rotate.

[0030] During operation, the drive component drives the first mounting base 210 to rotate, and the first mounting base 210 drives the first cutting blade 230 to rotate through the mounting arm 220, thereby achieving the purpose of cutting the pickled mustard greens. The structure is simple and the operation is convenient.

[0031] Preferably, multiple first cutting blades 230 and mounting arms 220 are provided in a one-to-one correspondence to improve the stability and reliability of cutting the pickled mustard greens leaves. In this embodiment, two mounting arms 220 and two first cutting blades 230 are provided.

[0032] Preferably, a battery is provided on the frame 100 to provide the power required for the drive components.

[0033] Of course, in other embodiments, the drive components can also be powered by a backpack portable power source.

[0034] like Figure 1 As shown, the first mounting base 210 can also reciprocate linearly between a first position and a second position along its own rotation center line. Specifically, when the first mounting base 210 is in the first position, the distance between the first mounting base 210 and the second cutting component is relatively large; when the first mounting base 210 is in the second position, the distance between the first mounting base 210 and the second cutting component is relatively small.

[0035] The drive assembly not only drives the first mounting base 210 to rotate around its own rotation center line, but also drives the first mounting base 210 to reciprocate linearly between a first position and a second position along its own rotation center line. Specifically, when the drive assembly drives the first mounting base 210 to rotate in the positive direction, the drive assembly also drives the first mounting base 210 to move from the first position to the second position; when the drive assembly drives the first mounting base 210 to rotate in the negative direction, the drive assembly also drives the first mounting base 210 to move from the second position to the first position.

[0036] The first cutting component provided in this embodiment enables the mounting base to move along its own axis towards or away from the second cutting component, thereby making it suitable for pickled mustard tubers of different heights during harvesting and improving the versatility of the entire device.

[0037] like Figure 1 and Figure 3 As shown, in this embodiment, the first end of the first cutting blade 230 is hinged to the mounting arm 220.

[0038] The first cutting assembly also includes a first elastic element 240, the two ends of which are connected to the first cutting blade 230 and the mounting arm 220, respectively. In its natural state, the first elastic element 240 applies a spring force to the first cutting blade 230 so that the first cutting blade 230 tends to rotate in the positive direction about its hinge center line.

[0039] During cutting, as the mounting frame moves from the first position to the second position, when the first cutting blade 230 comes into contact with the fleshy stem of the pickled mustard tuber, the fleshy stem exerts a reaction force on the first cutting blade 230. Under the action of this reaction force, the first cutting blade 230 is pushed to overcome the first elastic element 240 and rotate in the opposite direction, so as to avoid damaging the fleshy stem.

[0040] In this embodiment, the first elastic element 240 is a torsion spring. In other embodiments, the first elastic element 240 may also be a spiral torsion spring, a spring, etc.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the second cutting assembly includes a second mounting base 310 and a second cutting blade 320.

[0042] The second mounting base 310 is fixedly connected to the frame 100. The second cutting blade 320 is disposed on the second mounting base 310 and is movably connected to the second mounting base 310 so that the second cutting blade 320 can reciprocate between the third position and the fourth position.

[0043] The drive assembly is also used to drive the second cutting blade 320 to move from the third position to the fourth position or from the fourth position to the third position.

[0044] Specifically, when the drive assembly moves the second cutting blade 320 from the third position to the fourth position, the second cutting blade 320 can cut the root of the pickled mustard tuber to separate the root from the fleshy stem. When the drive assembly moves the second cutting blade 320 from the fourth position to the third position, the second cutting blade 320 is reset.

[0045] like Figure 1 and Figure 3 As shown, in this embodiment, the first end of the second cutting blade 320 is hinged to the second mounting base 310, and the second end can swing back and forth between the third and fourth positions around its own hinge center line, so that the second cutting blade 320 swings at a small angle, and the second end of the second cutting blade 320 can move a longer distance. Compared with linear motion, it saves more space, thereby achieving the purpose of making the structure of the entire device more compact.

[0046] like Figure 1 and Figure 4 As shown, in this embodiment, the second mounting base 310 is provided with a slot 311 that cooperates with the second cutting blade 320. During cutting, the cooperation between the second cutting blade 320 and the slot 311 improves the cutting effect. Simultaneously, the slot 311, in conjunction with the root of the pickled mustard tuber, also positions the entire device, thereby improving harvesting efficiency.

[0047] like Figure 1 , 3 As shown, in this embodiment, the drive assembly includes a motor 410, a drive gear 420, a driven gear 430, a screw 440, a transmission rod 450, and a transmission structure.

[0048] The motor 410 is fixedly mounted on the frame 100. The drive gear 420 is coaxially sleeved on the power output shaft of the motor 410, enabling the motor 410 to transmit power to the drive gear 420, thereby driving the drive gear 420 to rotate. The driven gear 430 is rotatably mounted on the frame 100, and the rotation center line of the driven gear 430 coincides with the rotation center line of the first mounting base 210. The driven gear 430 meshes with the drive gear 420, enabling the drive gear 420 to transmit power to the driven gear 430, thereby driving the driven gear 430 to rotate.

[0049] The screw 440 is fixedly mounted on the frame 100, and is coaxially arranged with and rotatably connected to the driven gear 430. The screw 440 is threadedly connected to the first mounting base 210, so that when the first mounting base 210 rotates, the screw 440 can drive the first mounting base 210 to move from the first position to the second position or from the second position to the first position. Specifically, when the first mounting base 210 rotates in the forward direction, the first mounting base 210 moves from the first position to the second position; when the first mounting base 210 rotates in the reverse direction, the first mounting base 210 moves from the second position to the first position.

[0050] The transmission rod 450 is disposed on one side of the screw 440. The axis of the transmission rod 450 is parallel to the axis of the screw 440. The first end of the transmission rod 450 is fixedly connected to the driven gear 430, and the second end passes through the first mounting base 210 and extends towards the second cutting assembly. The transmission rod 450 is slidably connected to the first mounting base 210 so that the transmission rod 450 can transmit power to the first mounting base 210 to drive the first mounting base 210 to rotate. At the same time, it also allows the first mounting base 210 to move along the length of the transmission rod 450.

[0051] Furthermore, the interaction between the transmission rod 450 and the first mounting base 210 can limit and guide the movement of the first mounting base 210 along its own rotation center line, thereby improving the stability and accuracy of the movement of the first mounting base 210. Preferably, multiple transmission rods 450 are provided to improve the reliability and stability of power transmission.

[0052] The transmission structure is mounted on the frame 100. When the first mounting base 210 moves to the second position, the transmission structure transmits the power of the first mounting base 210 to the second cutting blade 320, so as to drive the second cutting blade 320 to move from the third position to the fourth position.

[0053] Specifically, during harvesting, the motor 410 drives the drive gear 420 to rotate in the positive direction. The drive gear 420 drives the driven gear 430 to rotate, which in turn drives the first mounting base 210 to rotate in the positive direction via the transmission rod 450. The first mounting base 210, along with the first cutting blade 230, rotates together, thereby cutting the leaves of the pickled mustard tuber and achieving the purpose of separating the leaves from the fleshy stem. At the same time, under the action of the screw 440, the first mounting base 210 moves from the first position to the second position.

[0054] When the first mounting base 210 moves to the second position, the first mounting base 210 transmits power to the second cutting blade 320 through the transmission structure, thereby driving the second cutting blade 320 to move and cut the root of the pickled mustard tuber, thereby achieving the purpose of separating the fleshy stem of the pickled mustard tuber from the root.

[0055] After harvesting, the motor 410 drives the rotating gear to rotate in the opposite direction, the driving gear 420 drives the driven gear 430 to rotate, and the driven gear 430 drives the first mounting base 210 to rotate in the opposite direction through the transmission rod 450. Under the action of the screw 440, the first mounting base 210 moves from the second position to the first position.

[0056] The drive component provided in this embodiment has a simple structure and achieves the purpose of driving the first cutting component and the second cutting component to operate separately through only one motor 410. The structure is simple, and when the first mounting base 210 moves to the second position, the power is transmitted to the second cutting component through the transmission structure. No manual control is required, making the operation simpler and the harvesting efficiency higher.

[0057] Preferably, a protective box 120 is fixedly installed on the frame 100, and the drive gear 420 and driven gear 430 are disposed inside the protective box 120. During operation, the protective box 120 prevents vegetable leaves and other debris from being splashed onto the drive gear 420 and driven gear 430 during harvesting, thus ensuring that the power transmission between the drive gear 420 and driven gear 430 is not affected.

[0058] like Figure 5 As shown, in this embodiment, the drive assembly further includes a transmission element 460 and a transmission shaft 470. The transmission element 460 is disposed on the side of the protective housing 120 facing the second cutting assembly, and is sleeved on and rotatably connected to the screw 440. The transmission shaft 470 is hollow and is sleeved on and rotatably connected to the screw 440. The first end of the transmission shaft 470 is connected to the driven gear 430, and the second end extends outside the protective housing 120 and is connected to the transmission element 460. The first end of the transmission rod 450 is fixedly connected to the transmission element 460, and the second end is fixedly connected to the first mounting base 210.

[0059] During operation, the driven gear 430 drives the transmission element 460 to rotate via the transmission shaft 470, and the transmission element 460 drives the first mounting base 210 to rotate via the transmission rod 450. By positioning the transmission rod 450 outside the protective housing 120 and connecting the transmission element 460 and the driven gear 430 via the transmission shaft 470, the gap between the protective housing 120 and the transmission shaft 470 is reduced, even to the point of being flush, thereby improving the protection effect on the driving gear 420 and the driven gear 430. Simultaneously, the cooperation between the transmission shaft 470 and the protective housing 120 also limits the movement of the screw 440, thereby improving the stability of the screw 440.

[0060] Preferably, the transmission element 460 is disc-shaped or cylindrical to improve its rotational stability. At the same time, it generates a uniform centrifugal force during rotation, reducing local stress concentration and improving service life.

[0061] like Figure 1 and Figure 3 As shown, in this embodiment, the transmission structure includes a transmission arm 481, a cable 482, a second elastic element 483, and a drive block 484.

[0062] The middle part of the transmission arm 481 is rotatably connected to the frame 100, and the rotation center line of the transmission arm 481 is parallel to the rotation center line of the first mounting base 210.

[0063] Cable 482 is movably connected to frame 100. The first end of cable 482 is fixedly connected to drive arm 481, and the second end of cable 482 is connected to second cutter 320, so that drive arm 481 can drive second cutter 320 to move by transmitting power to second cutter 320.

[0064] The first end of the second elastic element 483 is connected to the frame 100, and the second end is connected to the second cutting blade 320. In its natural state, the second elastic element 483 applies a spring force to the second cutting blade 320, causing the second cutting blade 320 to tend to move from the fourth position to the third position. Specifically, in this embodiment, the second elastic element 483 is a spring. The two ends of the second elastic element 483 are respectively connected to the second cutting blade 320 and the second mounting base 310. In other embodiments, the second elastic element 483 can also be a torsion spring, a spiral torsion spring, etc.

[0065] The drive block 484 is disposed on the first mounting base 210, and when the first mounting base 210 moves to the second position, the drive block 484 can abut against the second end of the transmission arm 481 to drive the transmission arm 481 to rotate.

[0066] Specifically, during the cutting process, when the first mounting base 210 moves to the second position, the first mounting base 210 applies a force to the second end of the transmission arm 481 through the drive block 484, thereby driving the transmission arm 481 to rotate. The first end of the transmission arm 481 then applies a force to the second cutting blade 320 through the cable 482, thereby causing the cable 482 to move from the third position to the fourth position, thus achieving the purpose of cutting the root of the pickled mustard tuber.

[0067] After the cutting is completed, the second cutting blade 320 is driven to move from the fourth position to the third position under the elastic force of the second elastic element 483, so as to reset the second cutting blade 320 and wait for the next cutting.

[0068] The transmission structure provided in this embodiment is simple in structure, is a purely mechanical structure, and is reliable in operation.

[0069] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

When the driving component drives the second cutting blade to move from the third position to the fourth position, the second cutting blade can cut the root of the pickled mustard tuber; When the drive component drives the second cutting blade to move from the fourth position to the third position, it resets the second cutting blade. The first end of the second cutting blade is hinged to the second mounting base, and the second end is able to swing back and forth between the third and fourth positions around its own hinge center line. The driving component includes: The motor is fixedly mounted on the frame; The drive gear is coaxially mounted on the power output shaft of the motor; The driven gear is rotatably mounted on the frame, and the rotation center line of the driven gear coincides with the rotation center line of the first mounting base. The driven gear meshes with the driving gear. A screw is fixedly mounted on the frame and is coaxially arranged with the driven gear and rotatably connected to the driven gear. The screw is threadedly connected to the first mounting seat so that when the first mounting seat rotates, the screw can drive the first mounting seat to move from a first position to a second position or from a second position to a first position. A transmission rod is disposed on one side of the screw, the axis of the transmission rod being parallel to the axis of the screw. A first end of the transmission rod is fixedly connected to the driven gear, and a second end passes through the first mounting base and extends towards the second cutting assembly. The transmission rod is slidably connected to the first mounting base. A transmission structure is provided on the frame, which is used to transmit the power of the first mounting seat to the second cutting blade when the first mounting seat moves to the second position, so as to drive the second cutting blade to move from the third position to the fourth position; The transmission structure includes: The transmission arm has its middle part rotatably connected to the frame, and the rotation center line of the transmission arm is parallel to the rotation center line of the first mounting base; A cable is movably connected to the frame. The first end of the cable is fixedly connected to the transmission arm, and the second end of the cable is connected to the second cutting blade, so that the transmission arm can transmit power to the second cutting blade through the cable, thereby driving the second cutting blade to move. A second elastic element, with its first end connected to the frame and its second end connected to the second cutting blade, applies a spring force to the second cutting blade in its natural state, causing the second cutting blade to tend to move from the fourth position to the third position; and A drive block is disposed on the first mounting base, and when the first mounting base moves to the second position, the drive block can abut against the second end of the transmission arm, thereby driving the transmission arm to rotate.
