Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an environmentally friendly sweet potato vine active anti-entanglement harvesting and drying device. Background Art

[0002] Sweet potato is an excellent crop with a very wide planting area in my country. Sweet potato is mostly planted in ridge cultivation and the harvest season is early autumn. When harvesting sweet potatoes, the removal of sweet potato vines becomes a major problem. Sweet potato vines are generally long, and the sweet potato vines between rows are intertwined and difficult to separate. It is difficult to remove them cleanly, which seriously affects the mechanical harvesting of sweet potatoes. Currently, most of them are cut manually or crushed by simple machines and returned to the field. Manual cutting requires a lot of manpower and material resources. After drying and chopping, the sweet potato vines can be used as high-quality and nutritious silage for raising pigs, cattle and sheep, saving farmers a lot of expenses. Crushing and returning to the field will cause waste of sweet potato vines. In order to avoid straw burning and reduce damage to the air, crop straw is currently mostly crushed on the spot by using a vine-killing machine to promote straw return to the field and increase the rate of straw decay. The vine-killing machine is a blade fixed on a rotating shaft. The high-speed rotation creates a negative pressure inside the vine-killing machine frame, which adsorbs the straw and is then quickly crushed by the blade.

[0003] Current seedling-killing machines on the market generally suffer from technical shortcomings in their blades. For one thing, the blades are relatively simple, often with the same structure and blade shape. However, the complex shape of the tough and intertwined sweet potato vines makes a single blade type difficult to cope with. Furthermore, multiple blades are integrally fixed to the drive shaft. While this design simplifies assembly, it prevents targeted maintenance and replacement of individual blade components after long-term wear and tear, increasing overall maintenance costs and severely limiting the efficiency and affordability of seedling-killing operations. Therefore, we propose an environmentally friendly, active, anti-entanglement harvesting and drying device for sweet potato vines. Summary of the Invention

[0004] The object of the present invention is to provide an environmentally friendly sweet potato vine active anti-entanglement harvesting and drying device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an environmentally friendly sweet potato vine active anti-entanglement harvesting and drying device, comprising a frame, a drive shaft rotatably connected inside the frame, a protective shell rotatably connected to the upper surface of the frame, an adjustment device provided on the arc surface of the drive shaft, the adjustment device comprising a plurality of circular ring blocks, and the plurality of circular ring blocks are fixedly connected to the arc surface of the drive shaft, one end of the circular ring block is provided with three first grooves, the inner wall of the first groove is slidably connected with a serrated blade, the size of the serrated blade is adapted to the size of the first groove, the other end of the circular ring block is provided with three second grooves, the inner wall of the second groove is slidably connected with a straight-edged blade, the size of the straight-edged blade is adapted to the size of the second groove, and the three serrated blades and three straight-edged blades are distributed in a circular array with the axis of the drive shaft as the center.

[0006] The above components achieve the following: Through the adjustment mechanism, the sweet potato vines can be cut in multiple dimensions, effectively preventing entanglement and improving harvesting efficiency. During operation, the serrated blade utilizes its sawtooth structure to effectively cut and tear the sweet potato vines, especially suitable for processing tougher and thicker parts. The straight blade, with its sharp straight edge, enables clean cutting action. The two blades work together to cut the sweet potato vines from different angles and methods.

[0007] Preferably, one end of the circular ring block is fixedly connected to three first fixed blocks, a first threaded rod is inserted into the internal thread of the first fixed block, a first threaded hole is provided on the surface of the serrated blade, and the first threaded rod is threadedly connected to the inner wall of the threaded hole of the serrated blade; the other end of the circular ring block is fixedly connected to three second fixed blocks, a second threaded rod is inserted into the internal thread of the second fixed block, a second threaded hole is provided on the surface of the straight-edge blade, and the second threaded rod is threadedly connected to the inner wall of the second threaded hole of the straight-edge blade.

[0008] The above components achieve the effect of enabling regular replacement or maintenance of the serrated and straight-edged blades. During long-term use, if the serrated and straight-edged blades become worn from cutting sweet potato vines, affecting cutting quality and device performance, the operator can quickly remove and replace the worn blades by twisting the first and second threaded rods. This also facilitates regular inspection, cleaning, and polishing of the blades.

[0009] Preferably, the end of the first threaded rod away from the serrated blade is fixedly connected to a first circular shaft, and the arc surface of the first circular shaft is provided with a plurality of first strip grooves; the end of the second threaded rod away from the straight-edged blade is fixedly connected to a second circular shaft, and the arc surface of the second circular shaft is provided with a plurality of second strip grooves.

[0010] The effect achieved by the above components is: the staff can easily rotate the first threaded rod and the second threaded rod by rotating the first circular shaft and the second circular shaft, thereby realizing convenient disassembly and installation of the serrated blade and the straight-edge blade, improving the efficiency of blade maintenance and replacement; the first strip groove and the second strip groove increase friction, effectively avoiding slipping during manual operation.

[0011] Preferably, the surfaces of the serrated blade and the straight-edge blade are coated with a wear-resistant coating, and the wear-resistant coating is a titanium nitride coating.

[0012] The effects achieved by the above components are: titanium nitride wear-resistant coating can significantly improve the surface hardness and wear resistance of the blade, effectively slow down the wear rate of the blade, extend the service life of the blade, reduce the frequency of frequent replacement due to blade wear, and reduce equipment maintenance costs.

[0013] Preferably, an observation device is provided on the surface of the protective shell, and the observation device includes a square hole, which is opened on the surface of the protective shell, and the inner wall of the square hole is slidably connected with a transparent observation window, and the inner wall of the square hole is opened with two circular grooves, and slide grooves are opened on both sides of the transparent observation window, and the inner wall of the transparent observation window slide groove is fixedly connected with a spring, and the other end of the spring is fixedly connected with a round rod, and the round rod is slidably connected to the inner wall of the transparent observation window slide groove, the size of the round rod is adapted to the size of the circular groove, and the front end of the round rod is arc-shaped.

[0014] The aforementioned components achieve the following: By installing an observation device, operators can observe the internal blade cutting, sweet potato vine conveying, and drying processes in real time through a transparent observation window, promptly identifying problems such as blade entanglement and abnormal wear during the sweet potato vine harvesting and drying process. If the transparent observation window becomes stained, obstructing vision, or becomes damaged, it can be removed for cleaning or replacement, ensuring a clear view of the device's internal workings while facilitating maintenance and ensuring stable operation.

[0015] Preferably, two fixing rods are fixedly connected to the surface of the transparent observation window, and two fixing grooves are provided on the inner wall of the square hole, and the fixing rods are slidably connected to the inner walls of the fixing grooves.

[0016] The effect achieved by the above components is that the sliding of the fixing rod and the fixing groove on the inner wall of the square hole can quickly and accurately position the transparent observation window to the appropriate position, providing precise installation guidance and stable support for the transparent observation window.

[0017] Preferably, two arc-shaped holes are opened on the surface of the transparent observation window, the arc-shaped holes of the transparent observation window are connected with the transparent observation window slide, the arc surface of the round rod is fixedly connected with a connecting rod, and the connecting rod is slidably connected with the inner wall of the arc-shaped hole of the transparent observation window.

[0018] The effect achieved by the above components is: the connecting rod facilitates the disassembly of the transparent observation window. By pulling the connecting rod to move along the arc hole trajectory, the round rod can be flexibly controlled to enter and exit the circular groove, thereby realizing rapid disassembly of the transparent observation window.

[0019] Preferably, two screws are fixedly connected to the surface of the transparent observation window, and the arc surfaces of the screws are threadedly connected to a baffle.

[0020] The effect achieved by the above components is: the baffle limits the movement trajectory of the connecting rod, and when removing the observation window, it prevents the connecting rod from continuing to move forward under the influence of the spring, and then the transparent observation window will cause the round rod to constantly rub against the inner wall of the protective shell during the upward sliding process, thereby extending the service life of the components.

[0021] Preferably, the inner wall of the frame is provided with a cutting device, and the cutting device includes a plurality of U-shaped frames, and the plurality of U-shaped frames are fixedly connected to the inner wall of the frame. The inner wall of the U-shaped frame is slidably connected with a secondary blade, and a screw rod is inserted into the inner thread of the U-shaped frame, and one end of the screw rod abuts against the secondary blade. A plurality of third threaded holes are opened on one side of the U-shaped frame, and the size of the screw rod is adapted to the size of the third threaded holes. A threaded groove is opened on one side of the secondary blade, and the screw rod is threadedly connected to the inner wall of the threaded groove of the secondary blade.

[0022] The effect achieved by the above components is as follows: by setting up a cutting device, the auxiliary blade in the cutting device can flexibly adjust its position and angle through the cooperation of the U-shaped frame and the screw rod, so that it forms a cross-cutting layout with the serrated blade and the straight-edged blade. During operation, the three blades cut the sweet potato vines from different directions and angles. The auxiliary blade can cut into areas that the first two blades have not fully processed, and divide the sweet potato vines more finely. At the same time, the threaded connection between the screw rod and the U-shaped frame allows the operator to accurately adjust the position of the auxiliary blade in the U-shaped frame by rotating the screw rod, so as to better cooperate with the serrated blade and the straight-edged blade to meet the harvesting needs of sweet potato vines in different states.

[0023] Preferably, a plurality of L-shaped blocks are fixedly connected to the upper surface of the U-shaped frame, a connecting block is fixedly connected to the upper surface of the auxiliary blade, and the connecting block is slidably connected to the surface of the L-shaped block.

[0024] The effect achieved by the above components is: it provides precise guidance and stable support for the position adjustment of the auxiliary blade. When the connecting block contacts the surface of the L-shaped plate, the third threaded hole under the L-shaped plate will quickly align with the thread groove of the auxiliary blade, thereby facilitating the rapid adjustment of the position of the auxiliary blade for fixation.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. This invention utilizes an adjustment mechanism to achieve multi-dimensional cutting of sweet potato vines, effectively preventing vine entanglement and improving harvesting efficiency. During operation, the serrated blade utilizes its sawtooth structure to effectively cut into and tear the sweet potato vines, making it particularly suitable for handling tougher, thicker sections.

The auxiliary blade can cut into areas that the first two blades have not fully processed, and divide the sweet potato vines more finely. At the same time, the threaded connection between the screw rod and the U-shaped frame allows the operator to accurately adjust the position of the auxiliary blade in the U-shaped frame by rotating the screw rod, so as to better cooperate with the serrated blade and the straight-edged blade to meet the harvesting needs of sweet potato vines in different states.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1-8The present invention provides a technical solution: an environmentally friendly sweet potato vine active anti-entanglement harvesting and drying device, comprising a frame 1, a drive shaft 6 rotatably connected to the frame 1, a protective shell 2 rotatably connected to the upper surface of the frame 1, and an adjustment device 3 provided on the arc surface of the drive shaft 6. By providing the adjustment device 3, the sweet potato vines can be cut in multiple dimensions, effectively preventing the sweet potato vines from being entangled, and improving the harvesting efficiency. During operation, the serrated blade 303, with its serrated structure, can effectively cut into and tear the sweet potato vines, and is particularly suitable for processing tougher and thicker parts; the straight blade 305, with its sharp straight edge, can perform a neat cutting action. The two cooperate with each other to cut the sweet potato vines from different angles and methods. The surface of the protective shell 2 is provided with an observation device 4. By providing the observation device 4, the operator can observe the internal blade cutting, sweet potato vine conveying and drying status in real time through the transparent observation window 402, and promptly discover problems such as blade entanglement and abnormal wear during the sweet potato vine harvesting and drying operation. If the transparent observation window 402 becomes stained, obstructing vision, or becomes damaged, it can be removed for cleaning or replacement. This ensures a clear view of the internal workings of the device, facilitates maintenance, and ensures stable operation. A cutting device 5 is provided on the inner wall of the frame 1. By providing this cutting device 5, the auxiliary blade 52 in the cutting device 5 can be flexibly adjusted in position and angle through the cooperation of the U-shaped frame 51 and the screw rod 53, forming a cross-cutting arrangement with the serrated blade 303 and the straight-edged blade 305. During operation, the three blades cut the sweet potato vines from different directions and angles. The auxiliary blade 52 can cut into areas that the first two blades failed to fully treat, resulting in a more detailed segmentation of the sweet potato vines. Furthermore, the threaded connection between the screw rod 53 and the U-shaped frame 51 allows the operator to precisely adjust the position of the auxiliary blade 52 within the U-shaped frame 51 by rotating the screw rod 53, thereby better cooperating with the serrated blade 303 and the straight-edged blade 305 to meet the harvesting needs of sweet potato vines in different states.

[0040] The specific settings and functions of the adjustment device 3, the observation device 4 and the cutting device 5 are described in detail below.

[0041] like Figure 2 and Figure 3 as well as Figure 4As shown, the adjustment device 3 includes a plurality of circular blocks 301, and the plurality of circular blocks 301 are fixedly connected to the arc surface of the drive shaft 6. One end of the circular block 301 is provided with three first grooves 302, and the inner wall of the first groove 302 is slidably connected to a serrated blade 303, and the size of the serrated blade 303 is adapted to the size of the first groove 302. The other end of the circular block 301 is provided with three second grooves 304, and the inner wall of the second groove 304 is slidably connected to a straight-edged blade 305, and the size of the straight-edged blade 305 is adapted to the size of the second groove 304. The three serrated blades 303 and the three straight-edged blades 305 are distributed in a circular array with the axis of the drive shaft 6 as the center. One end of the circular block 301 is fixedly connected to three first fixed blocks 306, and the first threaded rod 307 is inserted into the internal thread of the first fixed block 306. A first threaded hole is provided on the surface of the serrated blade 303, and the first threaded rod 307 is threadedly connected to the inner wall of the threaded hole of the serrated blade 303. The other end of the circular block 301 is fixedly connected to three second fixed blocks 309, and the second threaded rod 310 is inserted into the internal thread of the second fixed block 309. A second threaded hole is provided on the surface of the straight-edge blade 305, and the second threaded rod 310 is threadedly connected to the inner wall of the second threaded hole of the straight-edge blade 305, thereby achieving the effect of regularly replacing or maintaining the serrated blade 303 and the straight-edge blade 305. During long-term use, when the serrated blade 303 and the straight-edged blade 305 are worn due to cutting sweet potato vines, affecting the cutting effect and device performance, the operator can quickly remove the worn blades for replacement by twisting the first threaded rod 307 and the second threaded rod 310, which is also convenient for regular inspection, cleaning, grinding and other maintenance work on the blades. The end of the first threaded rod 307 away from the serrated blade 303 is fixedly connected to the first circular shaft 308, and the arc surface of the first circular shaft 308 is provided with a plurality of first strip grooves 312. The end of the second threaded rod 310 away from the straight-edged blade 305 is fixedly connected to the second circular shaft 311, and the arc surface of the second circular shaft 311 is provided with a plurality of second strip grooves 31 3. The staff can easily rotate the first circular shaft 308 and the second circular shaft 311 to easily rotate the first threaded rod 307 and the second threaded rod 310, thereby realizing convenient disassembly and installation of the serrated blade 303 and the straight-edge blade 305, thereby improving the efficiency of blade maintenance and replacement. The first strip groove 312 and the second strip groove 313 increase friction, effectively avoiding slipping during manual operation. The surfaces of the serrated blade 303 and the straight-edge blade 305 are both coated with a wear-resistant coating, which is a titanium nitride coating. The titanium nitride wear-resistant coating can significantly improve the surface hardness and wear resistance of the blade, effectively slow down the wear rate of the blade, extend the service life of the blade, reduce the frequency of frequent replacement due to blade wear, and reduce equipment maintenance costs.

[0042] like Figure 5 and Figure 6 as well as Figure 7As shown, the observation device 4 includes a square hole 401, which is opened on the surface of the protective shell 2. The inner wall of the square hole 401 is slidably connected to a transparent observation window 402. The inner wall of the square hole 401 is provided with two circular grooves 403. Both sides of the transparent observation window 402 are provided with a slide groove. The inner wall of the slide groove of the transparent observation window 402 is fixedly connected to a spring 404. The other end of the spring 404 is fixedly connected to a round rod 405. The round rod 405 is slidably connected to the inner wall of the slide groove of the transparent observation window 402. The size of the rod 405 is adapted to the size of the circular groove 403. The front end of the circular rod 405 is arc-shaped. Two fixing rods 406 are fixedly connected to the surface of the transparent observation window 402. Two fixing grooves 407 are provided on the inner wall of the square hole 401. The fixing rods 406 are slidably connected to the inner wall of the fixing groove 407. The sliding of the fixing rods 406 and the fixing groove 407 on the inner wall of the square hole 401 can quickly and accurately position the transparent observation window 402 to the appropriate position, providing a precise installation for the transparent observation window 402. The guide and stable support, the surface of the transparent observation window 402 is provided with two arc holes, the arc holes of the transparent observation window 402 are connected to the transparent observation window 402 slide groove, the arc surface of the round rod 405 is fixedly connected with a connecting rod 408, and the connecting rod 408 is slidably connected to the inner wall of the arc hole of the transparent observation window 402, and the connecting rod 408 brings convenient operation for the disassembly of the transparent observation window 402. By pulling the connecting rod 408 to move along the arc hole trajectory, the round rod 405 can be flexibly controlled to enter and exit the circular groove 403, so that the transparent observation window 402 can be quickly disassembled, and the surface of the transparent observation window 402 is fixedly connected with two screws 409, and the arc surface of the screw 409 is threadedly connected with a baffle 410. The baffle 410 limits the movement trajectory of the connecting rod 408. When the observation window is disassembled, the connecting rod 408 is prevented from continuing to move forward under the influence of the spring 404, and the transparent observation window 402 will cause the round rod 405 to constantly rub against the inner wall of the protective shell 2 during the upward sliding process, thereby extending the service life of the parts.

[0043] like Figure 8As shown, the cutting device 5 includes a plurality of U-shaped frames 51, which are fixedly connected to the inner wall of the frame 1. The inner wall of the U-shaped frame 51 is slidably connected to the auxiliary blade 52. The U-shaped frame 51 is internally threaded with a screw rod 53, one end of the screw rod 53 abuts against the auxiliary blade 52, and one side of the U-shaped frame 51 is provided with a plurality of third threaded holes 54. The size of the screw rod 53 is adapted to the size of the third threaded holes 54. A threaded groove is provided on one side of the auxiliary blade 52. The screw rod 53 and the threaded groove of the auxiliary blade 52 are aligned. The inner wall is threadedly connected, and a number of L-shaped blocks 56 are fixedly connected to the upper surface of the U-shaped frame 51. The upper surface of the auxiliary blade 52 is fixedly connected to a connecting block 55. The connecting block 55 is slidably connected to the surface of the L-shaped block 56, thereby providing precise guidance and stable support for the position adjustment of the auxiliary blade 52. When the connecting block 55 contacts the surface of the L-shaped plate, the third threaded hole 54 under the L-shaped plate will quickly align with the thread groove of the auxiliary blade 52, thereby facilitating the rapid adjustment of the position of the auxiliary blade 52 for fixation.

[0044] Working Principle 1: With the rotation of the drive shaft 6 driving the rotation of the annular block 301 as the driving force, when cutting the sweet potato vines, the serrated blades 303 and the straight-edged blades 305 distributed in a circular array work together to exert different cutting advantages, completing the efficient cutting of the sweet potato vines. When the blades become worn due to long-term use, the operator utilizes the threaded connection characteristics of the first threaded rod 307 and the first fixed block 306, the threaded hole of the serrated blade 303, and the second threaded rod 310 and the threaded hole of the second fixed block 309, the straight-edged blade 305. By rotating the first circular shaft 308 and the second circular shaft 311, the operator can easily drive the first threaded rod 307 and the second threaded rod to rotate with the friction provided by the first strip groove 312 and the second strip groove 313, and remove the worn serrated blade 303 and the straight-edged blade 305 from the first groove 302 and the second groove 304 respectively for replacement. During the operation of the blade, the titanium nitride wear-resistant coating continuously protects the blade surface with its high hardness and wear resistance, slows down the wear rate of the blade, extends the normal working cycle of the blade, and ensures the long-term stable operation of the adjustment device 3.

[0045] Working principle 2: During installation, the fixing rods 406 on both sides of the transparent observation window 402 slide along the fixing grooves 407 on the inner wall of the square hole 401, providing precise positioning and stable support for the observation window, ensuring that its installation position is accurate. The spring 404 pushes the round rod 405 to fit into the circular groove 403 on the inner wall of the protective shell 2, so that the observation window is firmly fixed. The operator can observe the internal blade cutting, sweet potato vine transportation and drying status in real time through the transparent observation window 402, and promptly discover problems such as blade entanglement and abnormal wear during the sweet potato vine harvesting and drying operation. During disassembly, pull the connecting rod 408 to slide along the arc-shaped hole on the surface of the transparent observation window 402, driving the round rod 405 to move in the slide and disengage from the circular groove 403, thereby realizing the rapid disassembly of the observation window. The baffle 410 on the screw 409 limits the movement trajectory of the connecting rod 408, preventing the spring 404 from pushing the connecting rod 408 to move excessively during the disassembly process, avoiding continuous friction between the round rod 405 and the inner wall of the protective shell 2, protecting the components and extending their service life, making the installation, disassembly and use of the observation window safer, more efficient and durable.

[0046] Working Principle 3: The U-shaped frame 51 is fixed to the inner wall of the frame 1, providing space for the installation and sliding of the auxiliary blade 52. The screw 53 is threadedly connected to the U-shaped frame 51 and the auxiliary blade 52. The operator rotates the screw 53 to precisely adjust the position and angle of the auxiliary blade 52, so that it forms a cross-cutting pattern with the serrated blade 303 and the straight-edge blade 305, effectively processing sweet potato vines in different states. At the same time, the sliding cooperation between the L-shaped block 56 and the connecting block 55 provides a guide for the adjustment of the auxiliary blade 52, ensuring its stable movement. When the two come into contact, they can quickly achieve alignment and fixation between the threaded hole and the thread groove, improving the operational stability and cutting efficiency of the cutting device 5.
