Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a harvesting device for harvesting chili peppers in ridges. Background Technology

[0002] Chili peppers, as an important economic crop, are widely cultivated globally and used extensively in food processing, condiment preparation, and medicinal applications. However, traditional manual harvesting methods face a series of problems during the chili pepper harvesting process. First, manual harvesting requires a large labor input, especially in large-scale cultivation, where labor costs are extremely high. Furthermore, for regions with labor shortages or seasonal farms, the supply of manpower for manual harvesting is a significant challenge. Second, due to inconsistencies in manual operation, differences in harvesting force, and variations in appearance, manual harvesting can lead to unstable quality of the harvested chili peppers. These factors can have a long-term negative impact on the quality, shelf life, and market competitiveness of chili peppers. In addition, manual harvesting demands high physical strength from workers, easily leading to fatigue, injury, or excessive workload.

[0003] With the modernization of agriculture and the continuous advancement of technology, automated and mechanized harvesting solutions have become important ways to improve agricultural production efficiency and quality. Mechanical harvesting technology has been widely applied in the harvesting of other crops, such as wheat, corn, and rice. However, the development and application of mechanical harvesting technology in the field of chili peppers is relatively limited. This is mainly due to the unique characteristics of chili pepper plants, including plant height, the scattered distribution of fruits, and the delicate and fragile nature of the fruits, which presents several challenges and technical difficulties for mechanical harvesting.

[0004] In the "Chili Harvesting Device" disclosed in CN108781736A, electromagnets on the harvesting plates approach each other under magnetic attraction, causing the two harvesting plates to rotate and move closer around the hinge point. During this process, the electromagnets slide within the grooves, the first spring deforms, and the cutter moves with the electromagnets. When the two electromagnets slide to a certain position, the two cutters come into contact with the chili stems. The electromagnets continue to slide, and the cutters sever the chili stems, separating the chili peppers from the stems. The chili peppers are then positioned within the space formed by the two harvesting plates. The harvesting plates allow for cluster harvesting, eliminating the need to manually feed the chili peppers into the harvesting area and avoiding contact between hands and the cutters and harvesting plates, thus improving safety. However, this device can easily cause significant damage to the plants during harvesting and is not suitable for harvesting fruits from plants of different heights. Furthermore, the device contains complex components such as electromagnets, increasing costs and maintenance difficulty. Summary of the Invention

[0044] Furthermore, two pentagonal wheels 21 are provided, fixedly connected to the upper end of the rotating tray assembly 23. The two pentagonal wheels 21 are staggered in height and placed in opposite directions, and rotate in opposite directions, which facilitates the cutting and collection of pepper fruits. Specifically, one pentagonal wheel 21 is higher than the other pentagonal wheel 21, and the height difference is half the thickness of the pentagonal wheel 21. The rear end of the pentagonal wheel 21 is equipped with a first conveying assembly 24, which includes a track 241 and a first baffle 242. The track 241 is mounted on the rear end of the pentagonal wheel 21, and the first baffle 242 is fixed to the end of the track 241. A drive gear 243 connected to the track 241 is provided on the outer side of the first baffle 242, and the drive gear 243 drives the track 241 to transport pepper fruits.

[0045] The rotating pallet assembly 23 includes a turntable 231 and a pallet 232; the pallet 232 is mounted on the lower end of the turntable 231, which is used to fix two pentagonal wheels 21. The turntable 231 is provided with a fixing member 211 for mounting the pentagonal wheels 21.

The pallet 232 is used to support the track 241, the first baffle 242, and the turntable 231. The lifting assembly 22 includes several first lead screws 221 and a chain 222; the several first lead screws 221 are respectively mounted at the four corners of the pallet 232 and are interconnected by the chain 222. One of the first lead screws 221 is equipped with a driving member for driving the pallet assembly to move up and down. The drive unit, in conjunction with the first lead screw 221, drives the tray 232 to move up and down as a whole, thereby driving the harvesting device 2 to move up and down, making it easier to harvest peppers growing at different heights; this drive unit is fixed to the right end of the track 241 to drive the track 241 to move, conveying the pepper fruits and their mixture to the separation device 3.

[0046] The separation device 3 also includes a fixed bracket 32, a rotating rod 33, a gear set 34, a blower 35, a baffle support assembly 36, and a second conveying assembly 37; the second conveying assembly 37 has the same components as the first conveying assembly 24, and both transport the chili peppers to other devices via the track 241.

[0047] Two rotating rods 33 are connected to the fixed bracket 32. In this embodiment, one rotating rod 33 is fitted with five snowflake wheels 31, and the other rotating rod 33 is fitted with four snowflake wheels 31. The snowflake wheels 31 on the two rotating rods 33 are horizontally staggered. The two ends of the rotating rods 33 are connected to the gear set 34. The gear set 34 is connected to a driving component for driving the gear set 34 to rotate and drive the rotating rods 33 to rotate, thereby driving the multiple snowflake wheels 31 to rotate and separate the pepper fruits and their mixture.

[0048] Among them, the gear set 34 is fixed on both sides of the rotating rod 33 by the fixed bracket 32 ​​and drives the rotating rod 33 to rotate. Several snowflake wheels 31 are sleeved on the rotating rod 33 and rotate accordingly. The blower 35 is assembled below the baffle support assembly 36. The second conveying assembly 37 is assembled between the separation device 3 and the packaging device 4.

[0049] The right end of the fixed bracket 32 ​​is connected to the support assembly 36; the baffle support assembly 36 includes a ramp 361, a second baffle 362 and a support column 363; the upper end of the support column 363 is equipped with the ramp 361, and the two ends of the ramp 361 are respectively equipped with the second baffle 362. Specifically, the blower 35 is installed at the lower end of the support column 363; the support column 363 is connected to the frame 1 and is used to support the ramp 361 and the second baffle 362; the ramp 361 is mounted on one side of the separation device 3 and is used to guide the separated pepper fruits to slide down to the packaging device 4; there are two second baffles 362, which are mounted on both sides of the ramp 361.

[0050] The packaging device 4 includes a support platform 41, a storage bag assembly 42, an air pump 43, a slide rail 44, a compression wheel assembly 45, and a turntable 46. The support platform 41 is located at the rear end of the frame 1, and the storage bag assembly 42 is mounted on the upper end of the support platform 41 for placing self-sealing bags. The air pump 43 is mounted on the upper end of the storage bag assembly 42. The slide rail 44 is opened on the support platform 41 for guiding the air pump 43 to move within the slide rail 44. The compression wheel assembly 45 is connected to the storage bag assembly 42 for compacting and sealing the packaged chili bags.

[0051] An air pump 43 is mounted on the upper end of the storage bag assembly 42, and the upper end of the air pump 43 is fixedly connected to the turntable 46; a slide rail 44 is provided on the support platform 41 to guide the air pump 43 to move within the slide rail 44; a compression wheel assembly 45 is connected to the storage bag assembly 42 to compress and seal the packaged chili bags.

[0052] Furthermore, the storage bag assembly 42 includes a second lead screw 421 and a storage bag platform 422; the second lead screw 421 is mounted at the four corners of the support platform 41, and the storage bag platform 422 is mounted and fixed to the support platform 41 via the second lead screw 421. One corner of the second lead screw 421 is connected to a transmission component for driving the movement of the second lead screw 421; through the second lead screw 421 and this transmission component, the air pump 43 is aligned with the self-sealing bag. The air pump 43 inflates the self-sealing bag, facilitating the filling of the chili peppers into the bag, which is then offset to one side by a compression wheel assembly 45 via a slide rail 44. Under the compression of the compression wheel assembly 45, the bag is sealed and simultaneously transported out of the machine.

[0053] The compression wheel assembly 45 is equipped with a wheel drive gear 451 for driving the compression wheel assembly 45 to move. The air pump 43 is also equipped with a transmission component for driving the air pump 43 to start. The upper end of the air pump 43 is fixedly connected to the turntable 46. The turntable 46 is equipped with a transmission component for driving the turntable 46 to rotate. The upper end of the turntable 46 is connected to a support structure. The upper end of the support structure is connected to a second lead screw 421. The second lead screw 421 is equipped with a transmission component for driving the second lead screw 421 to move.

[0054] When harvesting chili peppers, the height of the chili pepper plants is observed. If the plants are too tall, the limit switch on the harvesting device 2 is pressed to activate the lifting assembly 22, which forces the tray 232 and the turntable 231 and the pentagonal wheel 21 at its upper end to descend as a whole. If the plants are too short, the first lead screw 221 and the chain 222 in the lifting assembly 22 will raise the tray 232 and the turntable 231 and the pentagonal wheel 21 at its upper end, adjusting the pentagonal wheel 21 to the appropriate height.

[0055] Two pentagonal wheels 21 are placed in opposite directions with their heights offset. The pentagonal wheels 21 rotate at high speed, which pulls the mature chili peppers at the top of the chili peppers inward and cuts them off. The cut chili peppers then enter the conveyor belt 241.

[0056] The track 241 moves to transport chili peppers and their mixture. There is no gap between the pentagonal wheel 21 and the track 241, which prevents the chili peppers from falling into the field when they enter the track 241, reducing damage to the chili peppers. At the same time, a first baffle 242 is also installed at the rear end of the track 241 to limit the movement path of the chili peppers after entering the track 241, so that they are not thrown out of the machine body and are only transported within this range, reducing transmission loss and maximizing the preservation of the harvested chili peppers and their mixture.

[0057] In this embodiment, the snowflake wheel 31 allows the chili peppers to pass through the gaps between the snowflake wheels 31 and fall into the second conveying assembly 37 below. The stems mixed in with the chili peppers are blocked on the snowflake wheel 31 because they are larger than the chili peppers. Under the tangential force of the rotation of the snowflake wheel 31, they are pushed outward down the slope 361, thereby achieving the initial separation of the chili peppers and the leaves.

[0058] After smaller impurities such as chili peppers and leaves fall through the gaps between the snowflake wheels 31, the blower 35 mounted below the baffle support assembly 36 blows the lighter impurities such as leaves out of the device, while the chili peppers fall further downwards, achieving a high degree of separation between the chili peppers and leaves.

[0059] The second conveying component 37 transports the separated chili peppers to the packaging device 4. The chili peppers are then packaged into self-sealing bags on the storage platform 422. The self-sealing bags are inflated by the air pump 43 to facilitate the filling of the chili peppers. The self-sealing bags filled with chili peppers are compressed and sealed by the compression wheel assembly 45, and then fall into the output platform at the outside of the device for convenient storage and transportation.

[0060] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
