Description

Technical Field

[0001] The present invention relates to the technical field of seed rain collection, and specifically provides a seed rain collection device adapted to various terrains. Background Art

[0002] Seed rain is the process of the spread of plant sexual propagules (seeds or fruits). Through a seed rain collector, seeds of different plant species in a specific area can be collected. Researchers can analyze characteristics such as the yield, size, shape, and quality of the seeds to understand the plant's reproductive investment strategy. The composition and quantity changes of seed rain can reflect the dynamic changes of plant communities. Using a seed rain collector to collect data can observe the succession process of plant communities. The collector can also help determine the distance and direction of seed spread. By setting multiple seed rain collectors at different positions and comparing the types and quantities of seeds collected at different positions, it is possible to understand how seeds are spread through media such as wind, animals, and water flow.

[0003] In the wild environment, the seed rain collector needs to have good stability to resist the influence of natural factors such as wind and rain and avoid being overturned by wildlife trampling. For some researchers who need to collect seeds at different locations, a portable seed rain collector has more advantages. At the same time, it is necessary to prevent the collected seeds from being eaten by birds or small animals, and a protective structure needs to be added to the collector. Moreover, the current seed rain collection devices have low applicability to different terrains. They have different heights on different terrains. In a multi-layer vegetation structure, if there are trees, shrubs, and herbs at the same time, the seeds of the high-layer vegetation may be missed because the height of the collector is not enough, while if the collector is too high above the ground surface, it is easily trampled by wildlife and is also easily affected by natural factors such as wind.

A drainage structure is provided on the inner cylinder assembly 5. When the inner and outer cylinder assemblies are inserted into the soil, the outer cylinder assembly 6 can close the drainage structure to prevent soil from blocking the drainage structure.

[0044] After the inner and outer cylinders are fixedly inserted into the soil, the support frame 1 can be raised above the height of the surface vegetation through the telescopic assembly 2, thereby raising the entrance of the collection net 7, which can adapt to terrains with vegetation on the surface such as grasslands. When used in terrains without vegetation on the surface such as sandy lands, the telescopic assembly 2 contracts and can be supported on the ground surface through the support part at the bottom of the support frame 1.

[0045] According to the attached Figure 2 , the support frame 1 has a square frame 11, and the four sides of the collection net 7 are sleeved on the fixing bosses 14 outside the square frame 11.

[0048] The pawl mechanism 3 further includes an unlocking assembly 32, and a slider 322 of the unlocking assembly 32 is arranged in a guide groove 223 on the guide cylinder 22; pressing the pressing portion 311 of the pawl arm 31 can make the pawl end 314 disengage from the ratchet teeth 211, and at this time, the slider 322 is pushed to approach the pawl arm 31; a clamping groove 313 is arranged at the tail end of the pressing portion 311, and a clamping block 321 on the slider 322 can be inserted into the clamping groove 313. Specifically, sliding structures are arranged on both sides of the slider 322, and the sliding structures cooperate with the guide groove 223 on the guide cylinder 22. The guide groove 223 is arranged at a position adjacent to the pawl arm 31, and the clamping block 321 is arranged at one end of the slider 322 close to the pawl arm 31. When the pressing portion 311 is pressed down, the tail end of the pressing portion 311 can extend into the interior of the slider 322, so that the clamping block 321 on the slider 322 can enter the clamping groove 313 on the pressing portion 311.

[0049] According to the attached Figure 7 , the folding leg 4 includes a first leg 41 and a second leg 42.

[0051] After the support frame 1 is lifted, in order to prevent it from being trampled by animals and other situations, the folding legs 4 at the lower part of the telescopic assembly 2 can be unfolded and support the ground, improving the stability of the support frame 1. At the same time, when the support frame 1 supports the ground close to the ground, the folding legs 4 can be received in the guide cylinder 22 of the telescopic assembly 2, reducing the ground clearance of the support frame 1, so that the support frame 1 can be placed more stably on the ground.
