Description

Technical Field

[0001] This invention relates to the field of chili harvester technology, specifically a self-propelled chili harvester. Background Technology

[0002] As a major producer and consumer of chili peppers, my country has chili pepper cultivation widely distributed across 28 provinces and regions. However, for a long time, chili pepper harvesting has relied primarily on manual labor. Manual harvesting is not only inefficient but also extremely labor-intensive, hindering the large-scale development of the chili pepper industry.

[0003] Existing machinery has drawbacks: While some farmers have developed simple chili harvesting machines, most only cut the chilies along with the vines, requiring subsequent separation of fruit and vine, making large-scale, high-efficiency field harvesting impossible. Existing chili harvesters on the market have many problems, often resulting in the mixed harvesting of mature and immature chilies. If mature chilies are harvested first, each plant must be sorted, leading to extremely low efficiency (only 1-2 acres can be harvested per day). If the entire chili plant is harvested to save time, immature small-diameter chilies (such as green chilies with a diameter <1cm) cannot meet processing or sales needs and must be discarded, resulting in a resource waste rate as high as 20%-30%, especially in chili-growing scenarios where chilies ripen in batches. Therefore, we have introduced a self-propelled chili harvester. Summary of the Invention

[0004] The purpose of this invention is to provide a self-propelled chili harvester to solve the problems mentioned in the background art.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This invention achieves a harvesting efficiency of up to 1 acre per hour by rotating the spoked rotating frame and the chili harvesting teeth, reducing reliance on manual labor, lowering labor costs, and enabling growers to complete the harvest in a shorter time, thus avoiding chili losses due to untimely harvesting.

[0031] The eccentric component ensures that the chili harvesting teeth remain horizontal during rotation, allowing the adjacent first and second teeth to accurately pick the chilies off the plant. This avoids the inability to pick the chilies off the plant smoothly due to tooth tilting, and prevents damage to the chilies. The chili damage rate is controlled to within 5%, significantly improving the quality and commercial value of the chilies.

[0032] The tooth pitch of the chili harvesting mechanism can be easily adjusted via the adjustable latch assembly, with an adjustment range of 0.5-5cm, adapting to the harvesting needs of different chili varieties. Whether it's small-diameter long peppers or large-diameter sweet peppers, precise harvesting can be achieved, effectively solving the problem of poor applicability of existing harvesters to different chili varieties, and improving the harvester's versatility and practicality.

[0033] The upper and lower harvesting teeth adopt a screwless detachable installation method. When the teeth are worn or damaged, they can be quickly replaced without tools. The maintenance time for a single tooth is reduced from the traditional 15 minutes to 2 minutes, which greatly reduces maintenance costs and downtime, improves the efficiency of equipment use, and ensures the continuity of chili harvesting.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Example:

[0068] Please see Figure 1-27 The present invention provides a technical solution:

[0069] A self-propelled chili harvester includes a chili harvesting assembly 3 mounted on the front end of a self-propelled vehicle 1 using a mounting frame 2;

[0070] Mounting frame 2 includes two sets of side frames 201, left and right. A connecting shaft 306 is provided on the outer side of the middle part of the spoke rotating frame 301. The connecting shaft 306 is inserted into the corresponding connecting hole on the side frame 201. A drive motor 4 is installed on the middle of the outer side of the right side frame 201. The connecting shaft 306 on the right side is fixedly connected to the output end of the drive motor 4. Alternatively, the engine inside the self-propelled vehicle 1 can use transmission components (engine output shaft, transmission gear, transmission chain, etc.) to drive the connecting shaft 306 on the right side.

[0071] The chili harvesting assembly 3 includes a spoke rotating frame 301 rotatably connected to the inner wall of the mounting frame 2, several sets of chili harvesting teeth 302 movably connected at equal intervals between the left and right spoke rotating frames 301, and an eccentric assembly connected to the right spoke rotating frame 301. When the spoke rotating frame 301 drives the chili harvesting teeth 302 to rotate, the eccentric assembly is used to ensure that the chili harvesting teeth 302 are in a horizontal state.

[0072] The chili harvesting tooth 302 has a left rotating shaft and a right rotating shaft 30215 at its left and right ends, respectively. The left rotating shaft and the right rotating shaft 30215 are fixed to the middle of the outer side of the corresponding left end cover 30205 and right end cover 30206, respectively.

[0073] The left and right rotating shafts 30215 are movably connected to the reserved holes 305 on the corresponding spoke rotating frame 301, and a square column 30216 is fixed at the right end of the right rotating shaft 30215.

[0074] After the connecting shaft 306 on the right side drives the spoke rotating frame 301 on the right side to rotate, several sets of chili harvesting teeth 302 will rotate.

[0075] The eccentric assembly includes a connecting plate 303 fixedly connected to a square column 30216 and an eccentric ring 304 movably connected to the other end of the connecting plate 303. The eccentric ring 304 is rotatably connected to several sets of arc-shaped grooves 202 on the inner wall of the side frame 201 on the right side.

[0076] One end of the connecting plate 303 is provided with a square through groove 3031 for engaging the square column 30216, and the other end of the connecting plate 303 is provided with a through hole 3032. Several sets of connecting pins 3041 are equally spaced on the inner side of the eccentric ring 304, and the connecting pins 3041 are inserted into the corresponding through holes 3032.

[0077] The eccentric component is used to ensure that the chili harvesting teeth 302 are in a horizontal state while the spoke rotating frame 301 drives several sets of chili harvesting teeth 302 to rotate clockwise upward, so that the adjacent first teeth 302084 and second teeth 302104 can pick the chili peppers from the chili pepper plant (the chili peppers on the chili pepper plant fall between the adjacent first teeth 302084 and second teeth 302104. As the chili harvesting teeth 302 rotates clockwise upward, the adjacent first teeth 302084 and second teeth 302104 move upward to pick the chili peppers from the chili pepper plant).

[0078] The chili harvesting tooth 302 includes a U-shaped groove seat 30201, a sealing plate 30211 fixed to the front end of the U-shaped groove seat 30201, an upper rack 30207 and a lower rack 30209 distributed vertically inside the U-shaped groove seat 30201, a drive gear 30204 meshing between the upper rack 30207 and the lower rack 30209, an upper harvesting tooth 30208 that can be detachably installed without screws at the front end of the upper rack 30207, a lower harvesting tooth 30210 that can be detachably installed without screws at the front end of the lower rack 30209, and an adjustment buckle assembly 30202 connected to the rear end of the drive gear 30204.

[0079] The sealing plate 30211 is fixed to the front end of the U-shaped groove seat 30201 by the first bolt 30213, and the left end cover 30205 and the right end cover 30206 are respectively fixed to the left and right ends of the sealing plate 30211 and the U-shaped groove seat 30201 by countersunk bolts 30214.

[0080] Driven gears 30203 are movably connected to the left and right sides of the U-shaped groove seat 30201. The driven gears 30203 mesh between the upper rack 30207 and the lower rack 30209. This further ensures that the upper rack 30207 and the lower rack 30209 are in a horizontal state when they move along the U-shaped groove seat 30201.

[0081] The front end of the upper rack 30207 is provided with upper slots 302071 at equal intervals;

[0082] The upper harvesting tooth 30208 includes several sets of first vertical slide blocks 302081 that are slidably connected to the U-shaped groove seat 30201 at equal intervals, an upper insert block 302082 fixed at the upper rear end of the first vertical slide block 302081, a first slider 302083 centrally located at the front end of the first vertical slide block 302081, and a first tooth 302084 located at the front end of the first slider 302083;

[0083] The upper insert block 302082 is inserted into the corresponding upper slot 302071. The first vertical slide block 302081 is located between the upper rack 30207 and the sealing plate 30211. The first slider 302083 slides in the horizontal slide groove 30212 in the middle of the sealing plate 30211.

[0084] This configuration ensures that the upper harvesting tooth 30208 can be detachably mounted on the front end of the upper rack 30207 without screws.

[0085] Since the first vertical slide block 302081 is located between the upper rack 30207 and the sealing plate 30211, it can limit the upper harvesting tooth 30208 and prevent the upper harvesting tooth 30208 from falling off the upper rack 30207.

[0086] Since several sets of equally spaced first vertical slide blocks 302081 slide in the U-shaped groove 30201, and the first slider 302083 slides in the horizontal groove 30212 in the middle of the sealing plate 30211, the first toothed member 302084 can also be adjusted to a horizontal position when the upper rack 30207 moves horizontally along the U-shaped groove 30201.

[0087] The front end of the lower rack 30209 is provided with lower slots 302091 at equal intervals;

[0088] The lower harvesting tooth 30210 includes several sets of second vertical slides 302101 that are slidably connected to the U-shaped groove seat 30201 at equal intervals, a lower insert block 302102 fixed at the lower rear end of the second vertical slide 302101, a second slider 302103 centrally located at the front end of the second vertical slide 302101, and a second tooth 302104 located at the front end of the second slider 302103;

[0089] The lower insert block 302102 is inserted into the corresponding lower slot 302091, the second vertical slide block 302101 is located between the lower rack 30209 and the sealing plate 30211, and the second slider 302103 slides in the horizontal groove 30212 in the middle of the sealing plate 30211.

[0090] This configuration ensures that the lower harvesting tooth 30210 can be detachably mounted on the front end of the lower rack 30209 without screws;

[0091] Since the second vertical slide 302101 is located between the lower rack 30209 and the sealing plate 30211, it can limit the lower harvesting tooth 30210 and prevent the lower harvesting tooth 30210 from falling off the upper rack 30207.

[0092] Since several sets of equally spaced second vertical slide blocks 302101 slide in the U-shaped groove 30201, and the second slider 302103 slides in the horizontal groove 30212 in the middle of the sealing plate 30211, the second toothed member 302104 can also be adjusted to a horizontal position when the lower rack 30209 moves horizontally along the U-shaped groove 30201.

[0093] The front ends of the upper harvesting tooth 30208 and the lower harvesting tooth 30210 extend out of the sealing plate 30211. By adjusting the buckle assembly 30202, the drive gear 30204 is rotated, thereby adjusting the distance between the upper harvesting tooth 30208 and the lower harvesting tooth 30210. Furthermore, the adjusting buckle assembly 30202 can also fix the distance between the upper harvesting tooth 30208 and the lower harvesting tooth 30210 by buckling the drive gear 30204.

[0094] The drive shaft 302041 at the rear end of the drive gear 30204 extends through the receiving hole in the middle of the rear end of the U-shaped slot seat 30201. The side wall of the receiving hole is provided with a snap-fit ​​tooth groove 30217, and the side of the drive shaft 302041 is provided with a snap-fit ​​protrusion 302042.

[0095] The adjusting buckle assembly 30202 includes a turntable 302021 disposed in a receiving hole, a cylindrical handle 302022 fixed at the middle of the rear end of the turntable 302021, and a buckle 302026 movably installed between the turntable 302021 and the cylindrical handle 302022.

[0096] A socket 302029 is provided between the middle of the turntable 302021 and the cylindrical handle 302022. The drive shaft 302041 is inserted into the socket 302029 and fixed with a fastening bolt 302023. The buckle protrusion 302042 is inserted into the corresponding inner groove 302028 on the side wall of the socket 302029.

[0097] The fastener 302026 includes an L-shaped pressing member 3020261, a pressing block 3020262 provided on the front of the horizontal part of the L-shaped pressing member 3020261, a locking block 3020264 provided on the vertical part of the L-shaped pressing member 3020261, and an elastic plate 3020263 provided on the back of the horizontal part of the L-shaped pressing member 3020261.

[0098] The turntable 302021 has a vertical slot 302025 at its front end, and the cylindrical handle 302022 has a horizontal slot 3020210 inside that communicates with the vertical slot 302025. The cylindrical handle 302022 also has a side through slot 302024 on its side that communicates with the horizontal slot 3020210.

[0099] The rear end of the horizontal part of the L-shaped pressing part 3020261 is movably connected to the horizontal slot 3020210 by a pin 302027, and the pressing block 3020262 extends out through the side through slot 302024.

[0100] Under the elastic force of the elastic plate 3020263, the locking block 3020264 at the front end of the L-shaped pressing member 3020261 extends through the vertical slot 302025 and is locked into the corresponding snap-fit ​​tooth groove 30217.

[0101] When it is necessary to adjust the distance between the adjacent first tooth 302084 and the second tooth 302104, hold the cylindrical handle 302022 and press the pressing block 3020262 with your thumb until the pressing block 3020262 retracts into the side through groove 302024. At this time, the L-shaped pressing part 3020261 is close to the elastic plate 3020263, and the locking block 3020264 on the L-shaped pressing part 3020261 retracts into the vertical slot 302025. The locking block 3020264 no longer engages in the buckle tooth groove 30217.

[0102] Then, rotating the cylindrical throttle 302022 causes the drive shaft 302041 to drive the drive gear 30204 to rotate, thereby causing the upper rack 30207 and the lower rack 30209 to move synchronously inside the U-shaped slot 30201, quickly adjusting the distance between the adjacent first tooth 302084 and the second tooth 302104.

[0103] Then, release the cylindrical throttle 302022, and stop pressing the pressing block 3020262 with your thumb. At this time, under the elastic force of the elastic plate 3020263 on the L-shaped pressing member 3020261, the locking block 3020264 on the L-shaped pressing member 3020261 extends through the vertical slot 302025 and is locked into the corresponding locking tooth groove 30217, thereby realizing the locking and fixing of the drive gear 30204 and ensuring the fixed position after the distance between the adjacent first tooth 302084 and the second tooth 302104 is adjusted.

[0104] After a chili pepper falls from the chili pepper plant between the adjacent first tooth 302084 and second tooth 302104, the larger, mature chili pepper can be retained and harvested.

[0105] Specifically, when using it:

[0106] 1. Power transmission: Drives the chili harvesting assembly 3 to rotate as a whole.

[0107] The equipment's power source has two adapter options to ensure stable operation under different working conditions:

[0108] Power input: ① The drive motor 4 on the outside of the right side frame 201 is directly fixed to the right connecting shaft 306 and outputs torque; ② If the drive motor is not applicable (such as heavy-duty operation), the power can be transmitted to the right connecting shaft 306 through the engine inside the self-propelled vehicle 1, via the transmission components such as "engine output shaft → transmission gear → transmission chain".

[0109] Motion transmission: The connecting shaft 306 is inserted into the connecting hole of the side frame 201, which drives the left and right sets of spoke rotating frames 301 to rotate clockwise synchronously (the rotation speed can be adjusted by the power source speed to match the self-propelled vehicle's travel speed, usually 10-15 r / min); the reserved hole 305 on the spoke rotating frame 301 cooperates with the left rotating shaft and right rotating shaft 30215 of the chili harvesting tooth 302, which drives several sets of chili harvesting tooth 302 to make circular motion with the spoke rotating frame 301, forming a "rotational harvesting trajectory".

[0110] 2. Horizontal maintenance: The eccentric component counteracts the circular motion, ensuring effective harvesting.

[0111] When the chili harvesting tooth 302 moves in a circular motion, if the chili harvesting tooth 302 tilts, it may cause chilies to be missed or the tooth to scratch the plant. Therefore, the eccentric component is the core to ensure harvesting accuracy, and its working mechanism is as follows:

[0112] Structural linkage: The right rotation shaft 30215 of the chili harvesting tooth 302 is fixed to the square column 30216, which is inserted into the square through groove 3031 of the connecting plate 303 (to avoid relative rotation); the other end of the connecting plate 303 is movably connected to the connecting pin 3041 of the eccentric ring 304 through the through hole 3032, while the eccentric ring 304 is fixed in the arc groove 202 on the inner wall of the right side frame 201 (its position does not move, it can only be rotated and adjusted).

[0113] Horizontal compensation principle: When the spoke rotating frame 301 drives the chili harvesting tooth 302 to rotate clockwise upward, the chili harvesting tooth 302 will perform "circular motion + radial offset" with the spoke rotating frame 301; at this time, the connecting plate 303 rotates in the opposite direction around the connecting pin 3041 of the eccentric ring 304, and the "eccentricity compensation" cancels the tilting effect of the circular motion of the spoke rotating frame 301 on the chili harvesting tooth 302, so that the picking end of the chili harvesting tooth 302 (the first tooth 302084 and the second tooth 302104) always remains in a horizontal state, ensuring that the chili harvesting tooth 302 is in vertical contact with the chili branches and improving the harvesting success rate.

[0114] 3. Tooth pitch adjustment: adaptable to different chili pepper sizes.

[0115] Different varieties or maturity levels of chili peppers vary significantly in diameter (e.g., long chili peppers are 0.8-1.2cm in diameter, and sweet peppers are 3-5cm in diameter). Therefore, "precise picking and filtering of small fruits" can be achieved by adjusting the tooth spacing (the distance between adjacent first tooth 302084 and second tooth 302104) of the buckle assembly 30202. The adjustment process is as follows:

[0116] Unlocking the latch: Hold the cylindrical handle 302022 and press the pressing block 3020262 protruding from the side through groove 302024 with your thumb, which will drive the L-shaped pressing part 3020261 to rotate around the pin 302027; the elastic plate 3020263 will deform under pressure, and the latch 3020264 will retract from the latch tooth groove 30217, releasing the fixation on the drive shaft 302041.

[0117] Adjusting the gear pitch: Rotate the cylindrical handle 302022, which, through the engagement of the insertion hole 302029 and the drive shaft 302041, drives the drive gear 30204 to rotate; the drive gear 30204 simultaneously meshes with the upper rack 30207 and the lower rack 30209, causing the two sets of racks to move horizontally and alternately along the U-shaped groove seat 30201 (if the upper rack 30207 moves to the left, the lower rack 30209 moves to the right, and vice versa), thereby changing the distance between the adjacent first gear 302084 and the second gear 302104 (adjustment range 0.5-5cm).

[0118] Locking and fixing: Release the pressing block 3020262, the elastic plate 3020263 releases its elastic force, pushes the L-shaped pressing part 3020261 to reset, the locking block 3020264 re-engages into the corresponding buckle tooth groove 30217, fixes the position of the drive gear 30204, and ensures that the pitch of the adjacent first tooth 302084 and the second tooth 302104 is stable.

[0119] When the self-propelled vehicle 1 moves forward, the first toothed component 302084 and the second toothed component 302104, which are in a horizontal state, move upward with the rotation of the spoke rotating frame 301, and catch the ripe pepper between the adjacent first toothed component 302084 and the second toothed component 302104; as the spoke rotating frame 301 continues to rotate clockwise, the pepper is pulled off the branch by the upward traction force of the adjacent first toothed component 302084 and the second toothed component 302104, and the harvesting is completed.

[0120] Immature, small-diameter peppers (smaller than the adjusted tooth spacing) leak out from the gap between adjacent first tooth 302084 and second tooth 302104, remaining on the plant to continue growing; mature, large-diameter peppers are firmly held in place by adjacent first tooth 302084 and second tooth 302104, and are harvested as they rotate upwards. The harvested peppers fall onto the conveyor belt below (not shown in the diagram, but located inside the self-propelled vehicle 1, with one end extending below the pepper harvesting component 3 and the other end extending above the collection box), and are finally transported to the collection box (located inside the self-propelled vehicle 1), achieving "harvesting ripe peppers and leaving green ones," thus reducing resource waste.

[0121] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
