Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery equipment, and in particular to a harvester for harvesting and cutting sea buckthorn into sections. Background Art

[0002] Sea buckthorn is a deciduous shrub of the genus Hippophae in the Elaeagnaceae family. In terms of morphology, it is about 1-15 meters tall, with many branches. Sea buckthorn is cold-resistant, barren-resistant, salt-alkali-resistant, light-loving and shade-intolerant. It blooms from April to May, starts to bear fruit in 4-7 years, and the fruiting period is from September to October. Ecologically, it has strong adaptability and is an excellent tree species for windbreak and sand fixation, and soil improvement in arid and semi-arid areas. It can effectively improve the local ecological environment and plays a positive role in soil and water conservation.

[0003] In the current field of sea buckthorn harvesting, there are mainly two completely different methods: manual harvesting and mechanical harvesting, each with its own advantages and disadvantages. Manual harvesting is the traditional way of harvesting sea buckthorn, which is more suitable for small-scale sea buckthorn planting areas or scattered sea buckthorn plant communities. When picking sea buckthorn fruits by hand, pickers can, based on experience and eyesight, accurately and specifically pick the fruits with just the right degree of maturity, ensuring the fruit quality to the greatest extent. However, the disadvantages of manual harvesting are also quite obvious. On the one hand, its harvesting speed is extremely slow. Pickers need to identify and pick each one carefully, consuming a large amount of time and energy, resulting in extremely low overall harvesting efficiency. When faced with a large-scale sea buckthorn orchard and the need to complete the harvesting task of a huge amount of fruits in a short time, manual harvesting is clearly inadequate. At the same time, the sea buckthorn branches are covered with sharp thorns. If pickers are not careful during the operation, parts such as the arms and palms are extremely likely to be scratched, which undoubtedly brings many potential risks to the pickers' bodies.

[0004] Mechanical harvesting: Most of the mechanical harvesting techniques currently in use adopt the principle of shaking off. Through special mechanical equipment, vibration is applied to the sea buckthorn tree trunks, and the force generated by the vibration is used to make the fruits fall off the branches, thereby achieving batch harvesting. Compared with manual harvesting, the working efficiency of mechanical harvesting has been greatly improved, and the number of sea buckthorn plants that can be processed within the same time has increased significantly. However, the net harvesting rate of mechanical harvesting is not satisfactory. Even after shaking, a considerable number of fruits will still remain on the branches, causing a certain degree of waste. Secondly, after harvesting one plant, the machine needs to be moved to the next sea buckthorn plant to start the harvesting process of the next plant, and it cannot achieve continuous and efficient harvesting as ideally. Particularly noteworthy is that during the critical season of sea buckthorn harvesting in autumn, in order to further improve the shaking-off effect, chemical agents often need to be sprayed to promote the fruit to fall off. However, this operation will greatly affect the taste of the fruits after spraying the agents. The originally rich sweet and sour flavor of the sea buckthorn fruits becomes bland, losing its unique charm. More seriously, these chemical agents are easily infiltrated into the soil and volatilized into the air, causing great pollution to the surrounding ecological environment, endangering the soil microbial community, affecting air quality, and may also indirectly threaten the survival and reproduction of the surrounding waters, animals and plants.

[0005] The present invention proposes a pruning-type sea buckthorn harvester that can perform flat cutting on sea buckthorn branches through a crescent-shaped rotary cutter and can achieve cutting segments. The crescent-shaped rotary cutting device of the present invention can perform flat cutting on sea buckthorn branches through a high-speed rotating crescent-shaped cutter. This design can make up for the problem of slow working efficiency of manual harvesting and greatly improve the cutting efficiency. The sea buckthorn branches are transported to the cutting segment device through a primary elevator. In the cutting segment device, the sea buckthorn branches can be cut into small segments of sea buckthorn branches, which is convenient for subsequent transportation of the sea buckthorn branches to the factory for freezing and fruit removal. Through these two processes, the working efficiency is greatly improved, the harvesting difficulty of large-scale sea buckthorn planting is reduced, and the possibility of rapid harvesting of sea buckthorn plants is provided. At the same time, the pruning device of the present invention can prune the side branches that cannot be flat cut by the harvester. The secondary elevator system can also transfer the sea buckthorn branches to the moving vehicle under the condition of continuous harvesting by the harvester, which can make up for the problem that the traditional sea buckthorn harvester cannot perform continuous harvesting and greatly improve the working efficiency. Summary of the Invention

[0006] Aiming at the deficiencies of the existing mechanical harvesting of sea buckthorn, the purpose of the present invention is to provide a self-propelled sea buckthorn harvester that can perform flat cutting and cutting segments, solve the problem that the existing sea buckthorn harvesting technology cannot perform self-propelled continuous operation, and at the same time, this machine can also cut the sea buckthorn branches into small segments of branches; it is convenient for the subsequent processing factory to perform freezing and fruit removal treatment on the sea buckthorn branches, and greatly improves the harvesting efficiency of sea buckthorn and the subsequent processing efficiency.

Specific embodiments

[0026] The present invention aims to provide an efficient and practical self-propelled seabuckthorn pruning harvester to meet the needs of seabuckthorn mechanized harvesting, cutting, and subsequent processing. The following will combine with the attached Figures 1-11 , comprehensively and deeply explain the technical details in each embodiment of the present invention. It should be clear that the embodiments shown here are only some typical examples of the invention, and the protection scope of the present invention covers all embodiments that can be derived by those of ordinary skill in the art based on the core concept of the present invention without creative work.

[0027] First, focusing on the overall structure of the machine, the key components of the self-propelled seabuckthorn pruning harvester of the present invention are made of high-strength, corrosion-resistant, and wear-resistant materials as a whole, ensuring long-term stable operation in the complex and harsh operating environment of the seabuckthorn plantation. As the core carrier, the body has a compact and reasonable layout, and each functional component can operate smoothly in coordination.

[0028] The crescent-shaped rotary cutting device. A branch-gathering deflector is precisely configured in front of it. The deflector adopts a reverse-flow design, and its surface is specially treated to reduce the friction coefficient between the branches and the deflector, which can efficiently and precisely deflect the branches of the seabuckthorn plant to the 8 small working areas of the crescent-shaped rotary cutting device. The crescent-shaped rotary cutting blade equipped with the crescent-shaped rotary cutting device is made of alloy steel with high hardness and toughness. Its performance is strengthened through heat treatment technology to ensure that it can remain sharp and durable when cutting seabuckthorn branches at high speed, realizing the rapid and stable mechanized harvesting of seabuckthorn branches. Combined with the branch-pushing wheel installed above the crescent-shaped rotary cutting device, the push bars, spacing, and rotation speed of the branch-pushing wheel are all optimized. When the cutting operation is in progress, the branch-pushing wheel rotates at an appropriate speed, cooperating with the cutting action of the crescent-shaped rotary cutting device, and smoothly pushing the cut seabuckthorn branches onto the first-stage elevator to ensure the smoothness of the branch conveying process.

[0029] The pruning device is equipped with a reciprocating pruning blade, and the blade is linked with the pruning hydraulic motor through a mechanical connection structure. The pruning hydraulic motor controls the movement frequency and stroke of the reciprocating pruning blade according to the growth characteristics and harvesting requirements of the seabuckthorn plant. During the actual operation, for the scattered branches that are difficult to gather by the branch-gathering deflector and the branches that escape from the side of the plant, the pruning device can respond quickly. Driven by the strong power of the hydraulic motor, the reciprocating pruning blade moves back and forth at a high frequency, trimming these redundant branches neatly, which not only ensures the harvesting efficiency but also is beneficial to the subsequent healthy growth of the seabuckthorn plant.

[0030] The first-stage elevator is scientifically and reasonably designed in structure. It mainly consists of a conveyor belt, a hydraulic motor, and a conveyor belt support. The conveyor belt is made of high-strength rubber material with anti-slip texture on the surface, so that there will be no slipping phenomenon during the process of transporting seabuckthorn branches. The drive connection between the hydraulic motor and the conveyor belt adopts an advanced gear reduction structure, which can ensure stable power transmission. At the same time, it can accurately control the running speed of the conveyor belt. Driven by the hydraulic motor, the conveyor belt runs stably in a clockwise direction, continuously transporting the seabuckthorn branches dropped by the crescent rotary cutting device and the branch-pushing wheel into the cutting device. Its conveying speed perfectly matches the processing rhythm of the subsequent cutting device, avoiding the accumulation and congestion of branches.

[0031] The cutting device is the key innovation point for the second-stage processing of seabuckthorn branches in the present invention. It mainly includes a pressing and pushing mechanism and a reciprocating cutting mechanism. The conveyor belt of the pressing and pushing mechanism is designed to rotate counterclockwise, forming a clever reverse rotation trend with the conveyor belt of the first-stage elevator. The two work together to form a trumpet-shaped structure that is large at the front and small at the back. During the transportation process, the fluffy seabuckthorn branches first enter this trumpet-shaped area. With the relative movement of the two conveyor belts, the branches are compacted, preparing for subsequent accurate cutting. In the reciprocating cutting mechanism, there are a cutting moving blade and a cutting fixed blade, both of which are forged from high-quality alloy steel to ensure sharp blades. The cutting moving blade is connected to the hydraulic motor through a high-strength connecting rod. The hydraulic motor drives the cutting moving blade to make a reciprocating up and down movement along the trajectory defined by the cutting support. When the compacted seabuckthorn branches enter the cutting area, under the close cooperation of the cutting moving blade and the cutting fixed blade, the branches are quickly cut into small sections of seabuckthorn branches with uniform cutting dimensions, meeting the subsequent processing standards. The cut small sections of seabuckthorn branches then fall into the storage box of the second-stage elevator and storage device behind.

[0032] The second-stage elevator and storage device is responsible for the important tasks of temporary storage and secondary transportation of branches. It consists of a translation section and a lifting section. The translation section is located at the bottom of the storage box and is equipped with a conveyor belt. When the storage box of the second-stage elevator is nearly full, the conveyor belt of the second-stage translation section at the bottom of the storage box starts, accurately translating the small sections of seabuckthorn branches to the side of the conveyor belt of the lifting section. The lifting section adopts a high-strength conveyor belt and scraper structure, and under the drive of the hydraulic motor, it lifts the seabuckthorn branches to a certain height. There is a sliding plate at this height position. The surface of the sliding plate is smooth and has a certain adjustable angle. When the small sections of seabuckthorn branches reach here, they will slide down along the sliding plate and fall into the truck transporting seabuckthorn. Thus, the entire mechanized harvesting process of seabuckthorn is completed. Each link is closely coordinated, greatly improving the efficiency of seabuckthorn harvesting and subsequent processing.

[0033] It should also be emphasized that in the technical description of the present invention, relative terms such as "certain" and "front", "rear", "upper", "lower", etc. are only used to clearly distinguish different entities, operations or components, and do not necessarily mean that there is a strict actual physical orientation relationship or operation sequence limitation between these entities and operations. In addition, the terms "comprising", "including" and their similar variants are intended to cover a series of elements in a non-exclusive manner, which means that when referring to a process, method, article or device "comprising" certain elements, it not only covers the explicitly listed elements, but also covers those elements that are inherent in or should be included based on conventional technology derivation for this process, method, article or device although not explicitly stated. Such a design provides a broader and more reasonable interpretation space for the technical solution of the present invention, ensuring its applicability and expandability in different application scenarios.
