TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural planting and harvesting, and in particular relates to a round leaf grape harvesting device. BACKGROUND

[0002] Round leaf grape is originally from the southeast of the United States, and has strong resistance to diseases and pests. It has been introduced into China for nearly 20 years and is cultivated in many places in the south. Its fruit has a strong subtropical fruit and flower aroma, and can be eaten fresh and used to make grape wine, juice, preserved fruit, jam and other processed products.

[0003] In the Chinese patent with publication number CN119969189A, a round leaf grape planting and picking method is disclosed, which includes planting plants in a wide row and dense planting manner, and there is a certain walking interval between the rows of plants. One side of each plant is provided with a plant support device, which includes a lower fixing seat, a lower support rod and an upper support rod. The lower fixing seat is fixedly buried in the field, and the lower fixing seat is fixedly installed with a lower support rod on the upper end face. The lower support rod is fixedly installed with a support spring, and the other end of the support spring is fixedly installed with an upper support rod. The side end faces of the upper support rod and the lower support rod are fixedly provided with a plurality of positioning rings for fixing the plants.

[0026] With reference to Figure 1 and Figure 2 , the buffer soft bag 5 extends into the harvesting bag 7, and a gap is reserved between the lower end of the buffer soft bag 5 and the bottom of the harvesting bag 7, so that the lower end of the buffer soft bag 5 is prevented from being stacked to cause the fruits to be unable to be discharged from the lower end of the buffer soft bag 5, the fruits roll in the buffer soft bag 5 and fall into the harvesting bag 7, the elastic telescopic pipe 4 is elongated with the increase of the weight of the fruits in the harvesting bag 7, so that the height of the upper part of the fruits in the harvesting bag 7 is substantially kept unchanged, and the fruits are prevented from being damaged by colliding with each other after falling. The elastic rope 8 connected to the discharge cylinder 3 is fixed to the connecting cylinder 6, the elastic rope 8 can be a rubber rope, and is used to assist the elastic telescopic pipe 4, so that the height of the upper part of the fruits in the harvesting bag 7 is kept unchanged by adjusting the tightness of the elastic rope 8 and cooperating with the elastic telescopic pipe 4.

[0030] Multi-point vibration effect analysis:

[0033] Overall harvesting benefit effect analysis:

[0034] 1. Reduce fruit damage: Cover from the top of the fruit tree and harvest, the fruit falls a short distance, directly into the harvesting bucket 18, reducing the damage caused by the collision of the fruit with branches, the ground, etc. during the process of falling from a high place to the lower collecting bucket, better guaranteeing the integrity and quality of the fruit; while covering from the bottom of the fruit tree, the fruit needs to fall a long distance, which is easy to be scratched and collided with branches during the falling process, and the damage probability increases significantly;

[0035] 2. Improve harvesting efficiency: When harvesting at the top, the fruit falling direction is single and clear, and the process of falling into the harvesting bucket 18 is more direct, which is convenient for centralized collection; when collecting at the bottom of the fruit tree, the fruit falling may be scattered everywhere due to branch obstruction, rebound, etc. Even if it rolls out of the collecting bucket range, it also needs to spend extra time and effort to find and pick up the missed fruit, which reduces the harvesting efficiency.

[0036] 3. More convenient operation: Cover the fruit tree with the harvesting bucket 18 at the top, the operator does not need to bend over or significantly bend over, which conforms to ergonomics, reduces labor intensity, and is not easy to fatigue after long-time operation; Collecting at the bottom of the fruit tree, the operator needs to bend over or squat on the ground for a long time, which is not only easy to fatigue, but also may affect the flexibility and accuracy of operation due to the inconvenience of posture.

[0037] 4. Avoid fruit contamination: Harvesting at the top, the fruit directly enters the harvesting bucket 18, reducing the opportunity to contact the ground, soil, etc. and reducing the risk of fruit contamination by soil, dust, bacteria, etc. Collecting at the bottom of the fruit tree, the fruit is easy to stain after falling to the ground, increasing the difficulty and cost of cleaning, and even some fruits may not be sold due to severe contamination.

[0038] 5. Adapt to more fruit tree shapes: For fruit trees with lush branches and dense fruit distribution, covering the harvesting bucket 18 from the top can better cover the fruit area, whether the fruit grows high or periphery, it can be effectively collected; Collecting from the bottom, it is easy to cause some fruits to be difficult to fall into the collecting bucket due to branch obstruction, especially high fruits, which may need additional tools to assist in picking, and the adaptability is poor.

[0039] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiment, but any equivalent modification or change made by a person skilled in the art according to the disclosed content of the present application shall be included in the protection scope recorded in the claims.
