Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically, it relates to a jujube harvester. Background Technology

[0002] Red dates, also known as jujubes, are a traditional Chinese medicine. They are the mature fruit of the jujube plant (Ziziphus jujuba), belonging to the Rhamnaceae family. The fruit is harvested in autumn when ripe, impurities are removed, and then it is sun-dried; or it is baked until the skin softens before sun-drying; or it is boiled briefly in water until the flesh is soft but the skin is not wrinkled, then sun-dried. Functions and indications: Tonifies the spleen and stomach, replenishes qi and generates fluids, regulates the body's defensive qi and blood, and detoxifies. It is used to treat poor appetite due to stomach deficiency, loose stools due to spleen weakness, insufficient qi, blood, and body fluids, disharmony between the body's defensive qi and blood, palpitations, and hysteria in women.

[0003] The current jujube harvesting is divided into the following types:

[0004] 1. Tree-shaking vibration type:

[0005] This type is not suitable for Xinjiang production areas, requiring ultra-large-scale planting with tree spacing greater than 1.5 to 2 meters. It does not meet the requirements for high-density planting with small single-row spacing in areas of 50 to 100 mu.

[0006] 2. Single-row, single-branch, riding-harvesting type:

[0007] This type of equipment does not meet the needs of farmers. Adapting to machine harvesting would reduce the quality of jujubes and decrease the yield. It would also require changes to existing planting methods; the high cost and low efficiency fail to meet practical and economic requirements.

[0008] 3. Self-priming type:

[0009] 1. The straw needs to be manually controlled. Local jujubes are large and heavy, and if the wind is too weak, they cannot be collected. If the wind is too strong, the dried fruit will collide with the tube wall at high speed, causing damage and peeling, which increases the defect rate of the dried fruit.

[0010] 2. Fallen fruit is mostly covered by leaves. The first batch of dried fruit to fall before the leaves fall will be covered by a deep layer of fallen leaves, making it difficult for the straw to effectively suck out this part of the dried fruit. In addition, the thick fallen leaves affect the operation of the straw. A large amount of fallen leaves leads to low harvesting efficiency and poor results. Dry sandy soil and loose soil cause huge dust, making it difficult to work effectively in the ground.

[0011] Foreign shaking harvesting equipment requires large-scale, widely spaced orchards, making it unsuitable for harvesting 50-100 mu (approximately 3.3-6.7 hectares) of single-row, high-density planting in China. Existing jujube harvesting machines in the Xinjiang market are only suitable for orchards with single-trunk pruning, which severely impacts jujube quality and yield, failing to meet growers' profitability. Furthermore, local orchards primarily use multi-trunk pruning, and this equipment's design limitations prevent it from directly harvesting from such orchards. Xinjiang's jujube production areas are concentrated in the southern desert region, where the fruit is large and heavy, making it difficult to effectively control suction strength. This results in a high rate of defective dried fruit, affecting profitability. Additionally, fallen leaves and sandy soil further hinder effective collection. Utility Model Content

[0012] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0013] To address the issues raised in the background regarding the foreign shaking harvesting equipment requiring large-scale, wide-spacing orchards, unsuitable for the 50-100 mu (approximately 3.3-6.7 hectares) single-row, high-density planting methods in China; the existing cycling jujube harvesting machines in the Xinjiang market are only suitable for orchards with single-trunk pruning, which severely impacts jujube quality and yield, failing to meet the profitability for growers; and the fact that local orchards are predominantly multi-branch pruning, the design limitations of this equipment prevent it from directly harvesting from orchards with multi-branch pruning; and the fact that Xinjiang jujube production is concentrated in the southern desert region, with large, heavy fruits that are difficult to control in terms of suction power, resulting in high rates of defective dried fruit and impacting profitability, and the inability to effectively collect fallen leaves and sandy soil, this invention adopts the following technical solution.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. By setting the first and second gathering components, the reverse rotation of the second drive motors on both sides enables the roller combers on both sides to rotate and gather the jujubes on the ground towards the center, preventing the jujubes from rolling outwards during vehicle movement. This results in a better gathering effect and easier collection of the jujubes. The rotation of the first drive motor drives the rotating soft brush to rotate, which in turn gathers the jujubes on the ground towards the center, making collection easier.

[0024] 2. Through the set collection components, the collection bucket can scoop up the jujubes and place them on the ribbed conveyor belt during the movement of the trolley, and transport them upwards. Multiple through slots can filter out mud, branches and other objects when scooping up the jujubes. As the ribbed conveyor belt is transported, the jujubes are transported to the crawler screen conveyor belt. The crawler screen conveyor belt can filter out dust and impurities on the jujubes, so that the jujubes are kept in a relatively clean state after collection. The motor drives the material-eating wheel to rotate, which transports the jujubes onto the ribbed conveyor belt.

[0025] 3. The extension and retraction of the third telescopic cylinder can raise or lower the bottom beam and the collecting bucket, thus allowing for adjustment according to the usage scenario. It can also simultaneously adjust the first and second retracting components.

[0026] 4. The blower can blow out the branches and soil mixed on the conveyor belt in the morning, making the collected dates cleaner.

[0027] 5. The extension of the first telescopic cylinder allows the adjusting plate and the lifting top cover to rotate, controlling the opening or closing of the two side fixing plates. This allows the spacing of the fixing plates to be adjusted according to the planting width. The extension and retraction of the fourth telescopic cylinder allows the fixing plates to be finely adjusted up and down, thereby allowing the first and second gathering components to be finely adjusted up and down. This allows the fixing plates and the L-shaped connecting plate to move up or down, so that the first and second gathering components can be lifted off the ground when the trolley moves, and then contact the ground when collecting the jujubes.

[0028] 6. Through the cooperation between the second telescopic cylinder and the third telescopic cylinders on both sides, the first and second retracting components can be kept parallel to the collecting bucket. Attached Figure Description
