Description

A kind of negative pressure for minimum particle diameter crop seed puts kind of a device

Technical field

This utility model relates to a kind of negative pressure for minimum particle diameter crop seed and puts kind of a device, belongs to modern agriculture scientific experiments technical field.

Background technology

The test of seed standard germination plays very important effect in terms of measuring percentage of seedgermination and seed vitality, and it is a kind of classics and important method, it is desirable to quantitatively program request, accurate several, uniformly positions.Use that manual program request is time-consuming takes a lot of work, inefficiency, error easily occurs, and the uniformity of program request varies with each individual, and affects testing result.Current application in the field of business to put kind of utensil kind more, wherein negative-pressure type puts that kind utensil efficiency is higher has advantage.Chinese patent " a kind of negative-pressure type depression location counting seed sowing device " (ZL 2011205477875, December in 2011 application on the 24th), although neat for a quantity of seeds can be positioned in culture medium by this device exactly, but the most helpless for seed that particle diameter is minimum.Chinese patent " tobacco seed sprouting bed-planting pen " (ZL 2009201928657, on August 31st, 2009 applies for), providing the instrument of putting being specifically designed to tobacco seed, the tobacco seed of minimum particle diameter can only be positioned over one by one appointment position by this hand-held tool, it is clear that its efficiency is the lowest.Minimum particle diameter crop seed such as tobacco seed, its particle diameter is typically about 0.60～0.80mm, wide about 0.40～0.55mm, mass of 1000 kernel only has 60～100mg, the thorny difficult problem that bed is industry is put for this type of seed, this utility model is intended to research and develop a kind of device, can implant culture medium like clockwork by the crop seed by minimum particle diameter in batches.

Utility model content

For above-mentioned the deficiencies in the prior art, this utility model provides a kind of negative pressure for minimum particle diameter crop seed to put kind of a device, it is intended to the crop seed of a certain amount of minimum particle diameter can be implanted culture medium, to improve work efficiency and work quality by like clockwork.

For achieving the above object, this utility model takes techniques below scheme: a kind of negative pressure for minimum particle diameter crop seed puts kind of a device, including seeds sucker, negative pressure cavity, cylinder and hands handle, piston and push rod, described seeds sucker is rectangle, its bottom surface arranges half hole matrix, a centrally disposed through hole at the bottom of the hole of each half bore of described half hole matrix, described through hole UNICOM negative pressure cavity, described cylinder and hands handle is connected on negative pressure cavity, described cylinder and handle are tubulose, its underpart is cylinder, top is hands handle, middle part arranges a manifold, manifold can connect flexible pipe to asepwirator pump, described piston coordinates with cylinder, piston upper end is provided with push rod, push rod stretches out at handle end, push rod top settings button, button have back-moving spring.

What a kind of negative pressure for minimum particle diameter crop seed of this utility model put that kind of device solves minimum particle diameter crop seed puts a difficult problem, and the design of its structure is simple effectively, uses simple operation, improves work efficiency and quality.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram that this utility model negative pressure puts kind of device, and Fig. 2 is that this utility model negative pressure is put the piston of kind of device and run on the structural representation under manifold, and Fig. 3 is the upward view that this utility model negative pressure puts kind of device.

In figure, 1, seeds sucker, 2, half bore, 3, negative pressure cavity, 4, through hole, 5, manifold, 6, piston, 7, push rod, 8, spring.

Detailed description of the invention

As shown in Fig. 1 Fig. 3, a kind of negative pressure for minimum particle diameter crop seed puts kind of a device, including seeds sucker 1, negative pressure cavity 3, cylinder and hands handle, piston 6 and push rod 7, described seeds sucker 1 is rectangle, its bottom surface arranges half hole matrix, a centrally disposed through hole 4 at the bottom of the hole of each half bore 2 of described half hole matrix, the aperture of through hole 4 is less than the aperture of half bore 2, described through hole 4 UNICOM negative pressure cavity 3, described cylinder and hands handle is connected on negative pressure cavity 3, described cylinder and handle are tubulose, its underpart is cylinder, top is hands handle, middle part arranges a manifold 5, manifold 5 can connect flexible pipe to asepwirator pump, described piston 6 coordinates with cylinder, piston 6 upper end is provided with push rod 7, push rod 7 stretches out at handle end, push rod 7 top settings button, button have back-moving spring 8.

Of the present utility model put kind of device work process be, with flexible pipe, manifold is connected with asepwirator pump, effect due to back-moving spring, piston is positioned at the position on manifold, opening negative pressure cavity when asepwirator pump is negative pressure, at this moment seeds sucker is paved with kind of a grain, each Kong Jun of half hole matrix has a seed to be adsorbed, unnecessary kind grain is removed with banister brush, then commitment positions seeds sucker moving to culture medium puts down, press the button, piston stops bleeding negative pressure cavity when running position to manifold, and the handle port emptying on manifold, when piston continues to run downwards, negative pressure cavity then transfers malleation to, at this moment the kind grain that seeds sucker is adsorbed is blown to commitment positions, this device is removed culture medium, decontroling button makes piston reset i.e. complete one-stop operation process.
