Description

Technical Field

[0001] This invention relates to the field of agricultural crops and pasture farming, specifically to a seed collection device. Background Technology

[0002] Herbaceous plant seeds mature in stages, and fall off as they mature, making it difficult to obtain large quantities of plump, mature seeds manually if not done promptly. This also results in excessively high costs and low harvesting efficiency. Furthermore, currently available seed collection devices require flat terrain and are not suitable for saline-alkali soils. Additionally, cutting the seed stalks often results in the flattening of most plants, especially grasses, rather than proper cutting. The patent application No. 2021231438234, entitled "A Seed Collection Device," features three rows of blades arranged at 120° angles to each other in the circumferential direction. When cutting the stems of plants such as chrysanthemums, due to their high water content and flexibility, they may not be able to be cut. If one of the 120° blades fails to cut the stem, the entire plant, including the roots, will be wrapped up on the horizontal bar connecting the 120° blade. The subsequent blades repeat this process, causing a large number of uncut stems of chrysanthemums to become entangled on the connecting horizontal bar and the connecting rod between the blades and the horizontal bar. Ultimately, the cutting becomes impossible due to the excessive entanglement of the plant. Summary of the Invention

[0003] The present invention aims to solve the technical problem that existing seed collection devices cannot perform cutting when cutting the stems of plants with high stem flexibility, such as those in the Asteraceae family, and provides a seed collection device accordingly.

[0004] The seed collection device of the present invention consists of a double-edged blade cutter 1, a first horizontal connecting plate 2, a pointed diverter 3, a seed collection cart 4, a first pulley 5, a belt 6, a vertical pipe 7, a second pulley 8, a diesel engine 9, a vehicle 10, a sleeve 11, a bushing 12, a rotating shaft 13, a bolt 14, and a second horizontal connecting plate 15.

[0005] The double-edged blade cutter 1 consists of multiple support rods 1-1, two double-edged blades 1-2, and a rotating shaft 13. One end of each support rod 1-1 is fixed to the rotating shaft 13 and is perpendicularly connected to the rotating shaft 13. The support rods 1-1 are distributed in two rows, each row consisting of multiple support rods 1-1 arranged parallel to each other, with the two rows forming a 180° angle. Both sides of each double-edged blade 1-2 are provided with a blade structure. One double-edged blade 1-2 is fixed to the end of each of the two rows of support rods 1-1 away from the rotating shaft 13, and the double-edged blade 1-2 is perpendicularly connected to the support rod 1-1.

[0006] The seed collection vehicle 4 is a hollow right-angled trapezoidal structure with an open front end and a vertical front end. A hinged rear cover 4-1 is provided at the rear end, forming a 75° angle with the bottom of the vehicle. A handle 4-2 is provided on the rear cover 4-1. The other four sides of the seed collection vehicle 4 are closed structures. A bushing 12 is provided on each side of the front end of the seed collection vehicle 4. A rotating shaft 13 is located inside the two bushings 12 and is rotatably connected to them. A first pulley 5 is provided at one end of the rotating shaft 13, located on the outside of the seed collection vehicle 4. A pointed diverter 3 is horizontally fixed at the lower front end of the seed collection vehicle 4. The pointed diverter 3 has multiple pointed structures with the pointed ends facing forward. The pointed diverter 3 is located directly below the double-edged blade cutter 1. When the double-edged blade 1-2 rotates to its lowest position, there is a gap between it and the pointed diverter 3. When the double-edged blade 1-2 rotates to its lowest position, it rotates towards the interior of the seed collection vehicle 4's canopy.

[0007] The vehicle 10 is located on the right side of the front end of the seed collection vehicle 4. The first horizontal connecting plate 2 is fixed to the left side of the rear end of the vehicle 10. A vertical pipe 7 is fixed below the first horizontal connecting plate 2. Multiple threaded holes 7-1 are provided on the vertical pipe 7 along the vertical direction. A sleeve 11 is provided on the lower part of the outer wall of the vertical pipe 7. A through hole is provided on the sleeve 11. The sleeve 11 and the vertical pipe 7 are connected together by bolts 14. The bolts 14 pass through the through hole and the threaded holes 7-1 on the sleeve 11. The sleeve 11 is fixed to the front end of the seed collection vehicle 4 through the second horizontal connecting plate 15. A diesel engine 9 is fixed on the second horizontal connecting plate 15. A second pulley 8 is provided at the power output end of the diesel engine 9. The second pulley 8 is connected to the first pulley 5 through a belt 6.

[0008] The method of using the seed collection device of the present invention is as follows: multiple threaded holes 7-1 are set on the vertical pipe 7 along the vertical direction. The appropriate height of the threaded hole 7-1 is selected according to the height of the herbaceous plant to be cut and the mature seeds so as to set the appropriate height of the double-sided blade 1-2 so as to cut the stem of the mature seeds and collect them into the seed collection vehicle 4. The vehicle 10 is started and the seed collection vehicle 4 is driven forward through the second horizontal connecting plate 15. The diesel engine 9 is started and the rotating shaft 13 is driven to rotate through the belt 6, thereby driving the double-sided blade 1-2 to cut the stem of the plant seeds. The cut seeds naturally enter the seed collection vehicle 4. After the collection is completed, the rear cover 4-1 is opened and the seeds are taken out.

[0009] The structure of the double-edged blade 1-2 in this invention is similar to that of a sword blade, with blades on both sides. Firstly, it can perform secondary cutting on individual uncut stems, ensuring that the efficiency of cutting and collecting seeds reaches more than 99%. Secondly, the double-edged blade can ensure the cutting and cleaning of the whole plant carried by the machine, preventing the connecting horizontal and vertical bars from getting stuck.

[0010] The pointed structure in the pointed diverter 3 serves two purposes: firstly, it can divert the densely growing herbaceous plants in grasslands, separating them into strands for easier harvesting; secondly, when the double-edged blades 1-2 are rotated to their lowest position, they are directly above the pointed diverter 3, forming a biting cutting surface. Furthermore, the pointed diverter 3 helps to place the stems of the herbaceous plants at the edge of the double-edged blades 1-2, thus smoothly collecting the seed spikes into the seed collection cart 4.

[0011] In this invention, the two double-sided blades 1-2 are at 180° to each other. Because the time interval between two adjacent blades at 180° is longer when they rotate compared to adjacent blades at 120°, and the longer blade at 180° has a larger cutting area, it is easier to cut the stems of plants such as chrysanthemums smoothly, and there will be no situation where the stems are caught on the crossbar due to untimely or uncut cutting.

[0012] In this invention, the blade is positioned between the vehicle 10 and the seed collection vehicle 4. Compared to placing it in front of the vehicle, this improves the collection efficiency by 66.67%. This is because placing the blade in the middle reduces the number of turns the vehicle 10 makes during seed collection, thus improving efficiency in terms of time. Additionally, the blade is angled upwards compared to the previous 120° blade, and the double-sided blade increases the cutting area. Overall, these three optimizations significantly improve efficiency by 66.67%.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The device of the present invention collects seeds quickly and has a high seed collection rate;

[0015] 2. The height of the double-bladed cutter 1 in the device of the present invention is adjustable, which can adapt to the height of herbaceous plants and mature seeds of different heights;

[0016] 3. The device of the present invention has low cost;

[0017] 4. The device of the present invention collects mature seeds of herbaceous plants in stages without affecting the growth of the plants, thereby maximizing the collection of mature seeds.

[0018] 5. This invention not only facilitates the collection of plant seeds, including those from the Poaceae and Asteraceae families, but also does not affect plant growth during the seed collection process, providing technical and equipment support for the rapid collection of required seed sources.

[0024] Specific Implementation Method 1: This implementation method is a seed collection device, such as... Figures 1-5 As shown, it is specifically composed of a double-edged blade cutter 1, a first horizontal connecting plate 2, a pointed diverter 3, a seed collection vehicle 4, a first pulley 5, a belt 6, a vertical pipe 7, a second pulley 8, a diesel engine 9, a vehicle 10, a sleeve 11, a bushing 12, a rotating shaft 13, a bolt 14, and a second horizontal connecting plate 15.

[0025] The double-edged blade cutter 1 consists of multiple support rods 1-1, two double-edged blades 1-2, and a rotating shaft 13. One end of each support rod 1-1 is fixed to the rotating shaft 13 and is perpendicularly connected to the rotating shaft 13. The support rods 1-1 are distributed in two rows, each row consisting of multiple support rods 1-1 arranged parallel to each other, with the two rows forming a 180° angle. Both sides of each double-edged blade 1-2 are provided with a blade structure. One double-edged blade 1-2 is fixed to the end of each of the two rows of support rods 1-1 away from the rotating shaft 13, and the double-edged blade 1-2 is perpendicularly connected to the support rod 1-1.

[0026] The seed collection vehicle 4 is a hollow right-angled trapezoidal structure with an open front end and a vertical front end. A hinged rear cover 4-1 is provided at the rear end, forming a 75° angle with the bottom of the vehicle. A handle 4-2 is provided on the rear cover 4-1. The other four sides of the seed collection vehicle 4 are closed structures. A bushing 12 is provided on each side of the front end of the seed collection vehicle 4. A rotating shaft 13 is located inside the two bushings 12 and is rotatably connected to them. A first pulley 5 is provided at one end of the rotating shaft 13, located on the outside of the seed collection vehicle 4. A pointed diverter 3 is horizontally fixed at the lower front end of the seed collection vehicle 4. The pointed diverter 3 has multiple pointed structures with the pointed ends facing forward. The pointed diverter 3 is located directly below the double-edged blade cutter 1. When the double-edged blade 1-2 rotates to its lowest position, there is a gap between it and the pointed diverter 3. When the double-edged blade 1-2 rotates to its lowest position, it rotates towards the interior of the seed collection vehicle 4's canopy.

[0027] The vehicle 10 is located on the right side of the front end of the seed collection vehicle 4. The first horizontal connecting plate 2 is fixed to the left side of the rear end of the vehicle 10. A vertical pipe 7 is fixed below the first horizontal connecting plate 2. Multiple threaded holes 7-1 are provided on the vertical pipe 7 along the vertical direction. A sleeve 11 is provided on the lower part of the outer wall of the vertical pipe 7. A through hole is provided on the sleeve 11. The sleeve 11 and the vertical pipe 7 are connected together by bolts 14. The bolts 14 pass through the through hole and the threaded holes 7-1 on the sleeve 11. The sleeve 11 is fixed to the front end of the seed collection vehicle 4 through the second horizontal connecting plate 15. A diesel engine 9 is fixed on the second horizontal connecting plate 15. A second pulley 8 is provided at the power output end of the diesel engine 9. The second pulley 8 is connected to the first pulley 5 through a belt 6.

[0028] The seed collection device of this embodiment is used as follows: multiple threaded holes 7-1 are set on the vertical pipe 7 along the vertical direction. The appropriate height of the threaded hole 7-1 is selected according to the height of the herbaceous plant to be cut and the mature seeds so as to set the appropriate height of the double-sided blade 1-2 so as to cut the stem of the mature seeds and collect them into the seed collection vehicle 4. The vehicle 10 is started and the seed collection vehicle 4 is driven forward through the second horizontal connecting plate 15. The diesel engine 9 is started and the rotating shaft 13 is driven to rotate through the belt 6, thereby driving the double-sided blade 1-2 to cut the stem of the plant seeds. The cut seeds naturally enter the seed collection vehicle 4. After the collection is completed, the rear cover 4-1 is opened and the seeds are taken out.

[0029] The structure of the double-edged blades 1-2 in this embodiment is similar to that of a sword blade, with blades on both sides. Firstly, it can perform secondary cutting on individual uncut stems, ensuring that the efficiency of cutting and collecting seeds reaches more than 99%. Secondly, the double-edged blades can ensure the cutting and cleaning of the entire plant carried by the machine, preventing the connecting horizontal and vertical bars from getting stuck.

[0030] The pointed structure in the pointed diverter 3 serves two purposes: firstly, it can divert the densely growing herbaceous plants in grasslands, separating them into strands for easier harvesting; secondly, when the double-edged blades 1-2 are rotated to their lowest position, they are directly above the pointed diverter 3, forming a biting cutting surface. Furthermore, the pointed diverter 3 helps to place the stems of the herbaceous plants at the edge of the double-edged blades 1-2, thus smoothly collecting the seed spikes into the seed collection cart 4.

[0031] In this embodiment, the two double-edged blades 1-2 are at 180° to each other. Because the time interval between two adjacent blades at 180° is longer when they rotate compared to adjacent blades at 120°, and the longer blade at 180° has a larger cutting area, it is easier to cut the stems of plants such as chrysanthemums smoothly, and there will be no situation where the stems are caught on the crossbar due to untimely or uncut cutting.

[0032] In this embodiment, the blade is positioned between vehicle 10 and seed collection vehicle 4. Compared to the front of the vehicle, this improves the collection efficiency by 66.67%. This is because with the blade positioned in the middle, vehicle 10 makes fewer turns during seed collection, thus improving efficiency in terms of turn-back time. At the same time, the blade is improved from the previous 120° blade, and the double-sided blade increases the cutting area. Overall, the optimization of these three parts greatly improves efficiency by 66.67%.

[0033] The beneficial effects of this implementation method are as follows:

[0034] 1. The device of this embodiment collects seeds quickly and has a high seed collection rate;

[0035] 2. The height of the double-bladed cutter 1 in the device of this embodiment is adjustable, which can adapt to the height of herbaceous plants and mature seeds of different heights.

[0036] 3. The device in this embodiment has low cost;

[0037] 4. The device of this embodiment collects mature seeds of herbaceous plants in stages without affecting the growth of the plants, thus maximizing the collection of mature seeds.

[0038] 5. This implementation method not only facilitates the collection of plant seeds, including those from the Poaceae and Asteraceae families, but also does not affect plant growth during the seed collection process, providing technical and equipment support for the rapid collection of required seed sources.

[0041] The double-edged blade cutter 1 consists of multiple support rods 1-1, two double-edged blades 1-2, and a rotating shaft 13. One end of each support rod 1-1 is fixed to the rotating shaft 13 and is perpendicularly connected to the rotating shaft 13. The support rods 1-1 are distributed in two rows, each row consisting of multiple support rods 1-1 arranged parallel to each other, with the two rows forming a 180° angle. Both sides of each double-edged blade 1-2 are provided with a blade structure. One double-edged blade 1-2 is fixed to the end of each of the two rows of support rods 1-1 away from the rotating shaft 13, and the double-edged blade 1-2 is perpendicularly connected to the support rod 1-1.

[0042] The seed collection vehicle 4 is a hollow right-angled trapezoidal structure with an open front end and a vertical front end. A hinged rear cover 4-1 is provided at the rear end, forming a 75° angle with the bottom of the vehicle. A handle 4-2 is provided on the rear cover 4-1. The other four sides of the seed collection vehicle 4 are closed structures. A bushing 12 is provided on each side of the front end of the seed collection vehicle 4. A rotating shaft 13 is located inside the two bushings 12 and is rotatably connected to them. A first pulley 5 is provided at one end of the rotating shaft 13, located on the outside of the seed collection vehicle 4. A pointed diverter 3 is horizontally fixed at the lower front end of the seed collection vehicle 4. The pointed diverter 3 has multiple pointed structures with the pointed ends facing forward. The pointed diverter 3 is located directly below the double-edged blade cutter 1. When the double-edged blade 1-2 rotates to its lowest position, there is a gap between it and the pointed diverter 3. When the double-edged blade 1-2 rotates to its lowest position, it rotates towards the interior of the seed collection vehicle 4's canopy.

[0043] The vehicle 10 is located on the front right side of the seed collection vehicle 4. The first horizontal connecting plate 2 is fixed to the rear left of the vehicle 10 (to the right of the left rear wheel of the vehicle 10, but very close to the left rear wheel). A vertical pipe 7 is fixed below the first horizontal connecting plate 2. Multiple threaded holes 7-1 are provided on the vertical pipe 7 along the vertical direction. A sleeve 11 is provided on the lower part of the outer wall of the vertical pipe 7. A through hole is provided on the sleeve 11. The sleeve 11 and the vertical pipe 7 are connected together by bolts 14. The bolts 14 pass through the through hole and the threaded hole 7-1 on the sleeve 11. The sleeve 11 is fixed to the front end of the seed collection vehicle 4 through the second horizontal connecting plate 15. A diesel engine 9 is fixed on the second horizontal connecting plate 15. A second pulley 8 is provided at the power output end of the diesel engine 9. The second pulley 8 is connected to the first pulley 5 through a belt 6.

[0044] The seed collection device used in this experiment is as follows: Multiple threaded holes 7-1 are set vertically on the vertical pipe 7. The appropriate height of the threaded hole 7-1 is selected according to the height of the herbaceous plant to be cut and the mature seeds so as to set the appropriate height of the double-edged blade 1-2 to cut the stems of the mature seeds and collect them into the seed collection vehicle 4. The vehicle 10 is started and the seed collection vehicle 4 is driven forward through the second horizontal connecting plate 15. The diesel engine 9 is started and the rotating shaft 13 is driven to rotate through the belt 6, thereby driving the double-edged blade 1-2 to cut the stems of the plant seeds. The cut seeds naturally enter the seed collection vehicle 4. After collection is completed, the rear cover 4-1 is opened and the seeds are taken out.

[0045] The structure of the double-edged blades 1-2 in this experiment is similar to that of a sword blade, with blades on both sides. Firstly, it can perform secondary cutting on individual uncut stems, ensuring that the efficiency of cutting and collecting seeds reaches over 99%. Secondly, the double-edged blades can ensure the cutting and cleaning of the entire plant being lifted by the machine, preventing the connecting horizontal and vertical bars from getting stuck.

[0046] The pointed structure in the pointed diverter 3 serves two purposes: firstly, it can divert the densely growing herbaceous plants in grasslands, separating them into strands for easier harvesting; secondly, when the double-edged blades 1-2 are rotated to their lowest position, they are directly above the pointed diverter 3, forming a biting cutting surface. Furthermore, the pointed diverter 3 helps to place the stems of the herbaceous plants at the edge of the double-edged blades 1-2, thus smoothly collecting the seed spikes into the seed collection cart 4.

[0047] In this experiment, the two double-edged blades 1-2 are at 180° to each other. This is because the time interval between two adjacent blades at 180° is longer when they rotate compared to adjacent blades at 120°. In addition, the longer blade at 180° has a larger cutting area, making it easier to cut the stems of plants such as chrysanthemums smoothly, and preventing them from being caught on the crossbar due to untimely or uncut cutting.

[0048] In this experiment, the blade was positioned between vehicle 10 and seed collection vehicle 4. Compared to placing it in front of the vehicle, this improved the collection efficiency by 66.67%. This is because placing the blade in the middle reduces the number of turns vehicle 10 needs to make during seed collection, thus improving efficiency in terms of turnaround time. Additionally, the blade's angle is improved compared to the previous 120° blade, and the double-sided blades 1-2 increase the cutting area. Overall, these three optimizations significantly improved efficiency by 66.67%.

[0049] The beneficial effects of this experiment are as follows:

[0050] 1. The device used in this experiment collects seeds quickly and has a high seed collection rate;

[0051] 2. The height of the double-edged blade cutter 1 in this experiment is adjustable, which can adapt to the height of herbaceous plants and mature seeds of different heights;
