Abstract

The utility model discloses a filtration pine wood nematode separation device which is composed of a gauze bag, a cylinder body assembly and a cup assembly. A first sealing ring, a first cylinder body, a pull rod, a first filter screen, a second cylinder body, a second filter screen, a third cylinder body, a third filter screen, a fourth cylinder body and a second sealing ring are connected in sequence to form the cylinder body assembly, a cup, a support, a base plate, a ball valve and a drain pipe are connected in sequence to form the cup assembly, pine wood samples are covered in the gauze bag and soaked in clear water in the cup, water is discharged (the samples are washed again, and water is discharged again) after the samples are soaked for a certain time, and pine wood nematodes soaked out are filtered by the filter screens. By the technical scheme, imagoes and larvae can be separated rapidly, and pine wood nematode separation effects and result reliability are improved greatly.

Description

Filtration method pine wood nematode tripping device

Technical field

The utility model relates to a kind of tripping device, is used for quick, the effectively separation of wood sample pine wood nematode (one-tenth, larva), belongs to pine wood nematode pick-up unit field.

Background technology

Pine nematode is claimed pine tree wilt disease again, is a kind of crushing epidemic disease of pine tree.This harmful destructiveness of being critically ill is: pathogenicity is strong, and the dead speed of host is fast; Propagate soon, and usually be taken by surprise; In case take place, difficulty of governance is big.Therefore, it is vital the pine wood nematode of wood sample inside being quarantined fast.

At present domestic relevant quarantine departments is used the graceful funnel method of Bel more at large and is carried out pine wood nematode and separate, and this method can't be separated one-tenth, the larva of pine wood nematode, and the later stage need carry out enrichment with hydro-extractor, structure is scattered, complicated operation.The patent of invention of having announced: the sheet washing method of rapid pine wood nematode separation technology (CN 101832899 A) is an experimental technique just, does not form concrete, the convenient operating means that uses.

The utility model content

The utility model purpose is to overcome above-mentioned deficiency, provide a kind of simply, at a low price, the device of easy operating, can separate one-tenth, the larva of pine wood nematode fast.

The purpose of the utility model is achieved in that a kind of filtration method pine wood nematode tripping device; Form by gauze bag, stack shell assembly and water tumbler assembly; O-ring seal one, stack shell one, pull bar, filter screen one, stack shell two, filter screen two, stack shell three, filter screen three, stack shell four, O-ring seal two are in turn connected into the stack shell assembly; Water tumbler, pillar, base plate, ball valve and drainpipe are in turn connected into the water tumbler assembly, parcel pine sample in the gauze bag, and be dipped in the clear water in the water tumbler.

The utility model filtration method pine wood nematode tripping device, said pillar has mesopore, can insert and transfer to the stack shell assembly, and porose ball valve, the drainpipe of being connected in pillar mesopore bottom forms discharge pipe line.

The utility model filtration method pine wood nematode tripping device for being threaded, can be realized packing into and splitting out of filter screen one, filter screen two and filter screen three between said stack shell one, stack shell two, stack shell three, the stack shell four.

The utility model filtration method pine wood nematode tripping device is equipped with O-ring seal one, O-ring seal two respectively on said stack shell one, the stack shell four, guarantees that clear water is all through discharging behind three filter screens in the stack shell assembly in the water tumbler.

The utility model filtration method pine wood nematode tripping device, said filter screen one, filter screen two, filter screen three are selected the descending filter screen in aperture for use, filter out impurity, adult and larva respectively.

The utility model filtration method pine wood nematode tripping device, but retaining and draining in the said water tumbler are used for the immersion and the washing of pine sample.

The utility model filtration method pine wood nematode tripping device, said gauze bag are packed into needs the pine sample of check.

Description of drawings

Fig. 1 is the utility model filtration method pine wood nematode tripping device embodiment synoptic diagram.

Fig. 2 is the decomposing schematic representation of stack shell assembly.

Fig. 3 inserts and transfers to stack shell assembly synoptic diagram from the water tumbler assembly.

Among the figure: gauze bag 1, water tumbler 2, O-ring seal 1, pull bar 4, filter screen 1, filter screen 26, filter screen 37, O-ring seal 28, pine sample 9, clear water 10, stack shell 1, stack shell 2 12, stack shell 3 13, stack shell 4 14, ball valve 15, drainpipe 16, base plate 17, pillar 18, water tumbler assembly 19, stack shell assembly 20.

Embodiment

Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation.

Shown in figure; The utility model filtration method pine wood nematode tripping device; Comprise: the stack shell assembly 20 that O-ring seal 1, stack shell 1, pull bar 4, filter screen 1, stack shell 2 12, filter screen 26, stack shell 3 13, filter screen 37, stack shell 4 14, O-ring seal 28 connect to form successively; The water tumbler assembly 19 that water tumbler 2, pillar 18, base plate 17, ball valve 15, drainpipe 16 connect to form successively, the gauze bag 1 of the pine sample 9 of packing into.

For being threaded, can realize packing into and splitting out of filter screen 1, filter screen 26 and filter screen 37 between said stack shell 1, stack shell 2 12, stack shell 3 13 and the stack shell 4 14.

Said stack shell assembly 20 can insert from the mesopore of pillar 18 and extract, and porose ball valve 15, the drainpipe 16 of being connected in the bottom of pillar 18 mesopores forms discharge pipe line.

The gauze bag 1 and clear water 10 of packing in the said water tumbler 2 and having wrapped up pine sample 9.

Said filter screen 1 is that 100 mesh filter screens, filter screen 26 are that 400 mesh filter screens, filter screen 37 are 500 mesh filter screens.

The concrete method of application of this embodiment is following:

Stack shell assembly 20 is inserted in the mesopore of pillar 18; The pine that need are detected is split into thickness and is no more than the wood chip that 5 millimeters, length and width are no more than 20 millimeters and forms pine sample 9; Entrain in the gauze bag 1, reinstall in the water tumbler 2, (available weight was pushed down gauze bag 1 to soaking pine sample 9 in water tumbler 2, to add clear water 10; It is submerged), the time that immersion needs: need to soak more than 12 hours with " the graceful funnel method of Bel "; Soaked 1～5 minute with " patent: the sheet washing method of rapid pine wood nematode separation technology ".Open ball valve 15, discharge water, put,, can repeatedly add water, discharge water and wash for guaranteeing that most pine wood nematode is dashed to filter screen 5, filter screen 6, filter screen 7 until water.After treating that water has been put, close ball valve 15, take out gauze bag 1; Hand-held pull bar 4; Stack shell assembly 20 is extracted from pillar 18, screwed off stack shell 1, stack shell 2 12, stack shell 3 13 and stack shell 4 14 from stack shell assembly 20 successively, filter screen 1, filter screen 26 and filter screen 37 are taken out successively; Filter screen 26 and filter screen 37 are soaked in respectively in the double dish of being with clear water with the suspension pine wood nematode, to isolate pine wood nematode.
