Abstract
The utility model provides a negative pressurized suction seed ditch distribution tool for testing experiments of crops seeds germination percentage, wherein negative pressure is formed in a tube cavity which communicates a row of suction nozzles and makes use of the negative pressure to suck seeds to the suction nozzles. The tube cavity is equipped with an air outlet valve which outlets air to relieve suctions and realize ditch distribution of a row of seeds when the sucked seeds are displayed on a culture medium. The utility model promotes adaptability, flexibility and high efficiency and is suitable for seeds samples with various diameters.
Description
Technical field
The utility model relates to a kind of negative-pressure adsorption-type seed and puts an instrument, and the seed that is used for agronomic crop seed germination rate determination experiment is put bed.
Background technology
In agronomic crop seed germination rate determination experiment, with the sampling of seed to be checked, the seed sample is put cultivated on the bedding more usually through some.For various reasons, put in the process manual, seed can occur and put uneven phenomenon, and speed is slower, influences experiment effect, operating efficiency is very low.Though also occur the seedbed setting up apparatus tool of some orifice-plate types in recent years successively,, and lack flexibility because the limitation of the array layout in the restriction in aperture and hole makes this class seedbed setting up apparatus tool all be only applicable to a certain specific seed.
Summary of the invention
In order to solve the drawback of above-mentioned manual difficulty and existing seedbed setting up apparatus tool, the utility model provides a kind of negative-pressure adsorption-type seed to put an instrument.The technical scheme that the utility model adopted is: with vavuum pump or dust catcher, in a tubular cavity, form negative pressure, this tubular cavity is communicated with the less tubulose suction nozzle of some internal diameters, utilize the principle of negative-pressure adsorption will plant the grain suction on the tubulose suction nozzle, this tubular cavity is provided with the venting valve, cultivate on the bedding when the seed that adsorbs is placed in, absorption is promptly removed in venting.
Specific design is: at an end of hand-holdable " T " font pipe fitting, be designed to gradually wide duckbill end, stretch out the less tubulose suction nozzle of row's internal diameter in this end, the other end of " T " font pipe fitting is provided with the venting valve, and the middle branch of " T " font pipe fitting connects vavuum pump.When vavuum pump is opened, " T " font tube intracavity is a negative pressure, and hand-held this " T " font pipe fitting of operating personnel is adsorbed on the seed to be checked of some on the one comb shape suction nozzle, cultivates on the bedding when the seed that is adsorbed is placed in, press the venting valve and remove absorption, promptly finish the bed of putting of a seeding.
Advantage of the present utility model is: compare seed with manual operations and put an efficient and greatly improve, owing to adopt the aperture negative-pressure adsorption, the seed sample applicable to the different-diameter different cultivars has improved its flexibility.
Description of drawings
Below in conjunction with accompanying drawing and instantiation the utility model is further specified.
Fig. 1 is a front view of the present utility model, and Fig. 2 is a left view, and Fig. 3 is the cutaway view of A-A section shown in Figure 1.
Among the figure, 1---the venting valve, 2---spring, 3---" T " font pipe fitting, 4---the exhaust tube interface, 5---the duckbill end, 6---the tubulose suction nozzle.
Embodiment
Press shape shown in the drawings and structure with nonmetallic materials, make the main body that seed is put an instrument with injection moulding or other technology: " T " font pipe fitting (3), its size dimension is held and is advisable to be suitable for common people, wall thickness is 3---and 6 millimeters, its underpart is gradually wide duckbill end (5), duckbill end (5) is provided with a comb shape suction nozzle (6), and this example is 12.The tip of tubulose suction nozzle (6) is an elastomeric material, and as Xiang Jiao Huo Xiang moulding material, its internal diameter is less, should be less than the 2.5. millimeter, and tubulose suction nozzle (6) internal diameter passage communicates with body cavity.Be provided with venting valve (1) on the top of " T " font pipe fitting (3), venting valve (1) locates to be equipped with spring (2) makes this valve be in normally off.Exhaust tube interface (4) should with the suitable and salable snap close of the mouth of pipe of vavuum pump or dust catcher.During implementation and operation, the flexible pipe mouth of pipe of vavuum pump or dust catcher is connected on the exhaust tube interface (4), hold this utensil top, thumb is placed on the venting valve (1), open vavuum pump, draw the seed sample and be placed on and cultivate on the bedding, press venting valve (1) and remove absorption, promptly finish the bed of putting of a seeding, unclamp the valve button and can draw the seed sample once more.
Claims (2)
1, a kind of negative-pressure adsorption-type seed is put an instrument, it is characterized in that, the bottom of " T " font pipe fitting (3) is gradually wide duckbill end (5), duckbill end (5) is provided with a comb shape suction nozzle (6), the top of " T " font pipe fitting (3) is provided with venting valve (1), and venting valve (1) locates to be equipped with spring (2).
2, negative-pressure adsorption-type seed according to claim 1 is put an instrument, it is characterized in that, the tip of tubulose suction nozzle (6) is an elastomeric material, and its internal diameter is less than the 2.5. millimeter.
