Description

Technical Field

[0001] This utility model relates to the field of harvester technology, and in particular to a zucchini seed harvester. Background Technology

[0002] As an economic crop with both edible and cultivation value, the efficiency and quality of zucchini seed harvesting directly impact the economic benefits for growers. Currently, zucchini seed harvesting faces the following industry pain points: First, the current industry status quo is still dominated by manual labor with insufficient mechanical intervention. Traditional harvesting relies on manual labor to complete multiple processes such as zucchini cutting, pulp extraction, and seed and pulp sorting. This is not only cumbersome and labor-intensive, but also prone to hand injuries due to improper use of tools. Furthermore, the squeezing action during manual pulp extraction can damage the seed structure, affecting the commercial value of the seeds and the germination rate. Even with the application of some basic mechanized equipment, the seed extraction method is mostly limited to rigid pushing. The equipment can only discharge the mixture of seeds and pulp, and cannot fully separate the seeds and pulp inside the zucchini, resulting in a high amount of seed residue. Furthermore, the hard contact during the pushing process further aggravates seed damage, making it difficult to balance harvesting efficiency and seed quality. Secondly, there are significant differences in size and maturity between different batches of zucchini, but the equipment lacks an effective material positioning and adjustment structure. This causes small-sized zucchini to easily shake and shift during operation, while large-sized zucchini has difficulty entering the working chamber smoothly, resulting in obvious limitations in size compatibility. On the other hand, some of the lightweight pulp inside the equipment cannot be effectively separated, requiring secondary manual sorting. The pulp is prone to sticking together, causing pipeline blockage and requiring frequent shutdowns for cleaning, which seriously affects the efficiency of continuous operation. Utility Model Content

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. In the seed extraction stage, the device uses a combination of conical guidance and spiral peeling. The conical structure reduces the insertion resistance of the zucchini and is suitable for the physical characteristics of materials with different maturity levels. The spiral peeling structure works synchronously with the axial advancement, which can fully peel the seeds and pulp along the zucchini axis, avoiding the seed compression and damage caused by traditional rigid pushing. In the separation stage, through the coordinated design of annular airflow field and flexible guidance, the annular airflow generating component can form a fully covered airflow area, eliminating the airflow blind spots of existing equipment. Combined with the flexible guidance structure, it provides differentiated guidance for the seeds and pulp. This system achieves precise separation of the two types of zucchini, eliminating the need for manual secondary sorting. This ensures the integrity of the seeds and significantly improves the continuity of the harvesting process, fundamentally balancing harvesting efficiency and seed quality. Furthermore, the device features a radial material positioning structure that stably clamps zucchini of different sizes, preventing shaking and displacement during operation. Combined with an adjustable axial propulsion stroke, it adapts to zucchini of different lengths and maturity levels, significantly enhancing the equipment's compatibility with diverse planting conditions. An airflow system with an integrated channel protection structure effectively prevents pulp fragments from entering the airflow pipeline, reducing the risk of blockage, extending continuous operation time, and lowering equipment maintenance frequency.

A bronchus 9 is installed in the slot 11. A first air delivery pipe 12 is installed at the end of the first branch bronchus 9. A through cavity 18 is opened in the push rod 16, and the first air delivery pipe 12 is installed in the through cavity 18. A connecting hole 15 is opened on the connecting post 14. A fixing ring 23 is installed in the main cavity 3. The fixing ring 23 is used to radially limit the zucchini placed in the main cavity 3 to prevent the zucchini from shaking or shifting during seed extraction, ensuring the accurate working path of the spiral blade 17. First air holes 13 are evenly distributed on the outer wall of the first air delivery pipe 12, and a second air hole 19 is opened on the push rod 16 at the position corresponding to the first air hole 13. The first branch bronchus 9 is connected through the connecting hole 15. A filter screen 20 is installed in the second air hole 19. The front end of the push rod 16 is... A cone-shaped tip 21 is provided, which facilitates penetration of the zucchini end, providing an initial channel for the spiral blades 17 to insert into the seed and pulp area and separate the seed and pulp mixture. An installation cavity 32 is located in the middle of the main cavity 3, containing a semi-annular air pipe 24. A connecting ring 25 is located on one outer wall of the semi-annular air pipe 24. A fixing hole 26 is located on one inner wall of the installation cavity 32 corresponding to the position of the connecting ring 25. The end of the second branch air pipe 10 is positioned within the connecting ring 25. The connecting ring 25 cooperates with the fixing hole 26 to stably fix the semi-annular air pipe 24 within the installation cavity 32, ensuring that the airflow delivered by the second branch air pipe 10 can stably enter the semi-annular air pipe 24. A feed inlet 22 is located on one outer wall of the main cavity 3, for the area awaiting harvest. The zucchini feeding channel, in conjunction with the fixing ring 23, allows the zucchini to accurately enter the working position within the main cavity 3. Air outlets 27 are evenly distributed on one side of the outer wall of the semi-circular air pipe 24, and each air outlet 27 is equipped with an air nozzle 28. A semi-circular flexible baffle 29 is installed on the inner wall of the front end of the main cavity 3. The semi-circular flexible baffle 29 is used to receive the separated zucchini seeds, guiding the seeds to slide towards the seed outlet 31, while reducing seed impact damage through flexible contact. A discharge port 30 is opened on one side of the outer wall of the front end of the main cavity 3, and a seed outlet 31 is opened at the front end of the main cavity 3. The discharge port 30 is used to discharge the pulp fragments blown away by the air nozzle 28, and the seed outlet 31 is used to collect the zucchini seeds guided by the semi-circular flexible baffle 29, achieving seed and pulp diversion and collection.

[0022] Working Principle: Using this invention, the bracket 2 is first fixedly installed on the upper surface of the base 1. The main cavity 3 is stably erected via the bracket 2 to accommodate the required operating height. The rear end of the main cavity 3 is sealed to the rear cover cavity 4. The through hole 5 on the rear cover cavity 4 provides a channel for power transmission. The cylinder 6 is fixed to the outer rear end of the rear cover cavity 4, and its output end can extend and retract axially along the through hole 5. The air pump 7 is also installed on the upper surface of the base 1 to provide an airflow source. A semi-annular air pipe 24 is provided in the mounting cavity 32 located in the middle of the main cavity 3. The semi-annular air pipe 24 is stably fixed by a connecting ring 25 on one side of the outer wall and a fixing hole 26 on the inner wall of the mounting cavity 32. A fixing ring 23 is also provided inside the main cavity 3, and the feed inlet 22 on one side of the outer wall serves as a channel for feeding the zucchini. The initial structural state before equipment operation is established. During operation, the zucchini to be harvested is first placed into the main cavity 3 through the feed inlet 22. The outer wall of the zucchini fits against the inner wall of the fixing ring 23, which provides radial positioning for the zucchini, preventing it from shaking or shifting during subsequent seed extraction to ensure accurate seed extraction path. Then, the cylinder 6 is activated, and the output end of the cylinder 6 pushes the connecting column 14 axially along the through hole 5 into the main cavity 3. The push rod 16, fixed at the front end of the connecting column 14, advances synchronously with the connecting column 14. The cone 21 at the front end of the push rod 16 first contacts the rear end of the zucchini. As the push rod 16 continues to advance, the cone 21 penetrates the end of the zucchini, creating a channel for seed and pulp separation. At the same time, the spiral blades 17 fixed to the outer wall of the push rod 16 advance axially with the push rod 16. As the push rod 16 rotates, the spiral structure of the spiral blade 17 gradually inserts into the seed and pulp area along the zucchini axis. Through the combined action of rotational shearing and axial pushing, the seed and pulp mixture inside the zucchini is separated from the zucchini body and transported to the front end of the main cavity 3 as the push rod 16 advances. At the same time as the push rod 16 advances, the air pump 7 is activated. The airflow output by the air pump 7 is divided into two paths through the main air pipe 8. One airflow enters the first branch air pipe 9, which extends along the groove 11 on the outer wall of one side of the rear cover cavity 4. Its end is connected to the first air delivery pipe 12, and the first branch air pipe 9 passes through the connecting hole 15 on the connecting post 14 to ensure the continuity of the air path. The first air delivery pipe 12 passes through the through cavity 18 inside the push rod 16 and moves synchronously with the push rod 16. The first air holes 13 evenly distributed on the outer wall of the push rod 16 and the corresponding second air holes 19 form an airflow channel. After the airflow enters the through cavity 18 through the first air hole 13, it is blown onto the surface of the spiral blade 17 through the second air hole 19, immediately blowing away the wet and soft pulp adhering to the spiral blade 17 to avoid blockage. At the same time, the filter screen 20 set in the second air hole 19 can filter impurities that may be mixed in the airflow to prevent impurities from contaminating the pulp mixture. Another airflow enters the second branch air pipe 10. The end of the second branch air pipe 10 is connected to the connecting ring 25 of the semi-annular air pipe 24. After the airflow enters the semi-annular air pipe 24, it is delivered to the air outlet nozzle 28 through the air outlet nozzles 27 evenly distributed on one side of the outer wall of the semi-annular air pipe 24. The air outlet nozzle 28 sprays annular airflow into the main cavity 3.When the seed and pulp mixture is pushed to the front end of the main cavity 3 by the push rod 16, under the action of the annular airflow, the less dense pulp fragments are blown by the airflow to the discharge port 30 opened on the outer wall of the front end of the main cavity 3 and discharged and collected from the port. The denser zucchini seeds, under the action of gravity, slide down along the semi-circular flexible baffle 29 set on the inner wall of the front end of the main cavity 3. The semi-circular flexible baffle 29 can prevent the seeds from hitting the inner wall of the main cavity 3 and causing damage, and at the same time guides the seeds to flow accurately to the seed outlet 31 opened at the front end of the main cavity 3. The zucchini seeds are discharged from the seed outlet 31 and the collection is completed. After a single harvest is completed, the output end of the cylinder 6 retracts in the opposite direction along the through hole 5, driving the connecting column 14, push rod 16 and spiral blade 17 to return to the initial position simultaneously. The air pump 7 stops supplying air. After the operator cleans the remaining pulp fragments from the discharge port 30, the next zucchini to be harvested can be put into the feed port 22. The above process is repeated to achieve continuous harvesting operation.
