Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "inner", "outer", "left" and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Example one

The invention discloses a field seed collector as shown in figures 1-2.A platform 4 is a circular flat plate, four through holes are uniformly arranged around the flat plate, a support rod 2 penetrates through each through hole, each support rod is connected with two nuts 3, and the support rods are fixed together by extrusion from the upper surface and the lower surface of the platform respectively. The upper part of each supporting rod is connected with a fan blade 1, and the connecting mode can be threaded connection or welding. The fan blade is of a circular arc-shaped structure, and the inner concave surface of the circular arc-shaped structure faces the outer side of the platform, so that wind power can be stored to the maximum degree, and the platform is driven to move by effectively utilizing the wind power. The width and the height of the fan blade are both larger than the height of the supporting rod but smaller than the diameter of the platform, the thickness of the fan blade is equal to that of the platform, and the design thickness standard is that the fan blade and the platform can swing and rock under the action of wind power but cannot deform per se. The seed drops on the platform surface, and when having wind, the fan blade is blown, drives the platform and rocks, and the seed slides on the platform, falls into the filter screen below when slipping through the position of first filter screen, and on the platform was fallen to light leaf, weeds etc. if, can be kept apart by the filter screen, can not mix in the seed, in addition because these impurity are lighter, can in time be blown away under the effect in the wind.

Be provided with first filter screen 11 at the center of platform, the setting mode can be to punch at first filter screen circumference, and the screw passes behind this hole with platform threaded connection, also can set up the slot on the platform, and first filter screen bottom sets up a plurality of jack catchs, and the jack catch inserts behind the slot that corresponds with round pin axle or fix with screw, and first filter screen sets up a plurality of circular meshes for keep apart impurity such as seed and leaf or weeds.

Be provided with flexible connection device in 4 belows on platform, this flexible connection device includes inside cylindrical spring 6 and outside elastic coating 5, cylindrical spring upper end and platform fixed connection, 8 fixed connection in storehouse are collected with the seed to the lower extreme. Elastic coating cladding is in cylindrical spring 6's outside, and elastic coating chooses for use waterproof sun-proof polyamide fibre elasticity cloth, the upper end and the platform lower fixed surface of elasticity cloth, and the storehouse upper surface is collected with the seed to the lower extreme of elasticity cloth fixed for collect the inside intercommunication in storehouse with platform upper portion and seed.

The storehouse is collected to the seed is conical structure, collects the entrance in storehouse 8 at the seed and sets up third filter screen 7, and this third filter screen sets up a plurality of circular meshes, and the diameter of mesh is less than the diameter of first filter screen for filter the impurity such as weeds or the leaf that first filter screen does not have the isolation, the mesh of third filter screen and the mesh dislocation set of first filter screen, the purpose of dislocation set is through the form of combination further reduce the filtration diameter of filtering the mesh. A second sieve 10 for isolating the seeds from the water is arranged at the bottom of the seed collecting bin, and the meshes or gaps of the second sieve are extremely small, so that the liquid is allowed to flow out, and the solid is not allowed to flow out. When water enters the seed collector through the first filter screen and the third filter screen in rainy and snowy weather, the water can flow out of meshes or gaps of the second filter screen.

The bottom in seed collection storehouse is provided with four landing legs 9, and the landing leg is kept apart the bottom in seed collection storehouse with the ground and is set for the distance, helps rainwater outflow seed collection storehouse, keeps the seed dry. When long and thin weeds or leaves are clamped at the meshes of the first or third filter screens, wind enters the seed collecting bin and the elastic connecting device from the bottom of the seed collecting bin through the second filter screen, wind power forms pressure larger than the outside in a narrow space, and weeds or leaves clamped at the meshes can be blown out to avoid blocking the filter screens.

Platform, fan blade, bracing piece, filter screen, seed collection storehouse and landing leg in the above-mentioned structure all select stainless steel processing preparation for use, and stainless steel has stronger corrosion resistance and higher hardness, and is high low temperature resistant, especially adapted equipment that is used for making and exposes in open-air service environment for a long time.

Example two

In this embodiment, flexible connection device chooses nylon sleeve or rubber sleeve for use, and the sleeve upper end is direct to be connected with the platform lower surface, and the sleeve lower extreme is connected with seed collection storehouse. Nylon or rubber have certain elasticity, are driven by the platform to deform or can return to the initial position under the action of restoring force, and have the advantages of low manufacturing cost, easy processing, wide material sources and higher cost performance.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
