[0025] In the present invention, the device for collecting seeds that are easy to crack or fall off is characterized in that the limiting mechanism realizes the limiting fixation of the winding roller by the cooperation of the sliding bar, the first gear, the insert block and other components, thereby preventing the winding roller from rotating on its own in the non-retracted state. The winding mechanism realizes the driving of the winding roller by the ingenious combination of the sliding seat, the rotating shaft, the second gear, the worm gear, the worm and other transmission mechanisms, so that the connecting net can be easily reeled or unfolded.

[0026] In the present invention, the device for collecting seeds that are easy to crack and fall off is provided with a connecting hole at the top of the connecting net, and two adjacent connecting nets are buckled together by a tension spring. When seeds fall on the connecting nets, the elastic action of the tension spring drives the adjacent connecting nets to slightly fit together, thereby better adapting to seeds of different sizes and shapes and preventing seeds from leaking from the mesh holes. At the same time, the provision of the tension spring also enables the connecting net to maintain a certain stability under the influence of external factors such as wind, thereby preventing the connecting net from shaking and dislocation.

[0027] In the present invention, the connecting net is arranged on the first support frame and the second support frame so that the seeds can be guided. At the same time, the two adjacent connecting nets are located between two rows of plants and are connected by tension springs, which makes the use more stable and the length of the connecting net can be easily adjusted. It can be suitable for plants of different areas and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0037] Reference Figure 1-Figure 7 A collecting device includes: a first supporting frame 1, a second supporting frame 4, a connecting shaft 6, a winding roller 2, a connecting net 3, a collecting basket 5, a limiting mechanism and a winding mechanism.

[0038] The first support frame 1 is a solid frame structure, with a connecting shaft 6 fixedly provided inside the first support frame. The connecting shaft 6 is arranged horizontally and runs through the entire first support frame 1 to provide rotation support for the winding roller 2.

[0039] Multiple winding rollers 2 are rotatably sleeved on the outer wall of the connecting shaft 6. Each winding roller 2 includes a connecting roller 7 fixedly sleeved on the connecting shaft 6, and a connecting tube 8 fixedly sleeved on the outer wall of the connecting roller 7. A connecting net 3 is fixed and wound around the outer wall of the connecting tube 8. The connecting net 3 is made of a soft and elastic material to facilitate winding or unfolding. One end of the connecting net 3 is clamped with the second support frame 4 to form a stable connection, and the connecting net 3 as a whole is inclined between two adjacent rows of plants to facilitate guiding the seeds.

[0040] Two groups of connection holes 36 are evenly opened on the top of the connection net 3, and a tension spring 37 is connected between each two opposite connection holes 36 in the two groups. The setting of multiple tension springs 37 enables two adjacent connection nets 3 to fit together when not subject to external force, thereby increasing the tightness of the connection net. At the same time, the tension springs 37 are located on both sides of the branches to avoid interference with the branches of the plant.

[0041] The collecting basket 5 is arranged in the second support frame 4, and its position corresponds to the end of the connecting net 3 close to the second support frame 4, so as to receive the seeds that slide down from the connecting net 3. The collecting basket 5 is made of a material that is easy to clean and replace, so as to facilitate the collection and subsequent processing of seeds.

[0042] When the winding roller 2 needs to be released, the sliding bar 14 is pulled by external force so that the plug 16 is away from the tooth groove of the first gear 17, thereby releasing the limit of the winding roller 2. One end of the sliding bar 14 is fixed with an arc block 19 used to cooperate with the rotating shaft 21, which is used to increase the contact area between the sliding bar 14 and the rotating shaft 21; one side of the connecting shaft 6 is also provided with a first guide rod 15 corresponding to the sliding bar 14, one end of the first guide rod 15 is fixedly connected to the sliding bar 14, and a first spring 18 is sleeved on its outer wall. The two ends of the first spring 18 are respectively fixedly connected to the sliding bar 14 and the outer wall of the connecting shaft 6, providing a reset elastic force for the sliding bar 14.

[0043] The reel 2 is rotated by the second gear 22 and the second gear 23 is engaged with the first gear 17, and the reel 2 is rotated by the second gear 22 and the second gear 17.

[0044] In order to realize the disengagement or engagement of the second gear 22 with the first gear 17 to control the rotation of the winding roller 2, a sliding plate 10 is slidably set inside the first support frame 1 along its length direction. The sliding plate 10 and the inner wall of the first support frame 1 are smoothly slid by a slide rail or a slide groove structure. On the inner side of the first support frame 1, a fixed bar 9 is fixedly set. On one side of the fixed bar 9, a rotatable first screw 12 is installed. The axis of the first screw 12 is parallel to the moving direction of the sliding plate 10. At the bottom of the sliding plate 10, a screw is fixedly set. The mother block 11 and the nut block 11 are provided with threads matching the first screw 12, so that the nut block 11 can move along its axial direction as the first screw 12 rotates. By rotating the first screw 12, the nut block 11 drives the sliding plate 10 to slide along the inside of the first support frame 1, and the second gear 22 provided on the sliding plate 10 moves accordingly, thereby achieving disengagement or engagement with the first gear 17 on the winding roller 2. When the two are engaged, the first gear 17 can be driven to rotate by an external power source, thereby driving the winding roller 2 and the connecting net 3 to be wound or unfolded.

[0045] The present application can be used in the field of collection devices, and can also be used in other fields applicable to the present application. Example 2

[0046] refer to Figure 1-Figure 7, improved on the basis of Example 1: a seed collecting device for easy pod cracking and easy falling off, which is applied to the field of collecting devices. To ensure the accurate positioning of the sliding seat 13 on the sliding plate 10, a mounting hole 26 is opened at the bottom of the sliding seat 13, and a pin 28 is slidably set in the mounting hole 26. The diameter of the pin 28 is slightly smaller than the diameter of the mounting hole 26 to achieve smooth sliding. At the top of the sliding plate 10, a plurality of positioning grooves 29 corresponding to the winding roller 2 are opened along its height direction. Each positioning groove 29 is used in conjunction with the pin 28, and a second spring 27 is set in the mounting hole 26. The two ends of the second spring 27 are fixedly connected to the top wall of the mounting hole 26 and the top of the pin 28 respectively. When the sliding seat 13 moves to the desired position, the pin 28 automatically slides into the corresponding positioning groove 29 under the elastic force of the second spring 27, thereby achieving accurate positioning of the sliding seat 13.

[0047] In order to achieve height adjustment of the second support frame 4, a second guide rod 32 is slidably set at the top of one side of the second support frame 4, and the bottom of the second guide rod 32 is fixedly connected to a base 30 to increase its stability. At the top of the other side of the second support frame 4, a second screw 31 is threadedly set, and the lower end of the second screw 31 is rotatably set on the top of the base 30, and the upper end of the second screw 31 extends out of the second support frame 4 for easy rotation operation. By rotating the second screw 31 and utilizing its threaded cooperation with the second support frame 4, the second support frame 4 can slide up and down along the second guide rod 32, thereby adjusting its height. This design enables the device to adapt to plants of different heights and improves the flexibility and adaptability of use.

[0048] At one end of the connecting net 3, a connecting strip 35 is fixedly set, and a rectangular opening 33 corresponding to the connecting net 3 is opened at the top of one side of the second support frame 4. The length and width of the connecting strip 35 should be suitable for passing through the rectangular opening 33 of the second support frame 4. On both sides of the rectangular opening 33, one or more limit blocks 34 are respectively set. The limit blocks 34 are used to limit the position of the connecting strip 35 in the rectangular opening 33 to prevent it from shaking or falling off.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
