Description

Bamboo inserting tube

The utility model relates to the utensil of taking care of the dispensing fumigating insecticide that is used for storing in a warehouse and makes the field.

In the grain storage keeping process, when adopting insecticide such as aluminum phosphate to carry out the fumigant insect killing processing, the general employing at grain heap in bulk surface fixed point dispensing aluminum phosphate cartridge bag, and under airtight situation, fumigate, as, to warehouse space in addition airtight (closing the doors and windows) or in addition airtight to the grain heap with plastic film.The closed fumigating method of this grain heap surface dispensing cartridge bag, its major defect is, this fumigating method has determined that the distributional difference of gaseous state insecticide concentration on the aspect of the different depth of grain heap is bigger, past more depths, concentration on the aspect obviously reduces, thereby it is relatively poor to the insecticidal effect of depths aspect.

The purpose of this utility model is to overcome above-mentioned weak point and a kind of bamboo inserting tube is provided, and when adopting the utility model to carry out the fumigant insect killing processing, can improve the insecticidal effect of grain heap in bulk depths aspect part.

The purpose of this utility model is realized by the following technical programs: a kind of bamboo inserting tube comprises the bamboo drum that inserts grain heap, internal run-through when using; Offer plural pore on the side of this bamboo drum; That the little head end of this bamboo drum is provided with is wooden, be convenient to the garden cone blocking head inserted down in the grain heap.

After adopting above technical scheme, when carrying out the fumigant insect killing processing, the utility model is inserted grain heap in bulk, again toward wherein loading fumigation medicament, the pore of medicament gas on bamboo drum that is produced outwards overflowed, directly be penetrated into grain heap depths aspect, thereby solved the problem of the depths aspect insecticidal effect difference of prior art.According to the test of real storehouse, its result is as follows: deposit 650 tons of paddy in No. 1 storehouse, and 4.7 meters of grain stack heights, set up an office and insert 3 meters long the utility model and load aluminum phosphate in many places, (can seal the utility model openend), and adopt coverlay film grain heap; Deposit 430 tons of paddy in No. 2 storehouses, 4.6 meters of grain stack heights adopt the aluminum phosphate cartridge bag to scatter the grain face and add coverlay film grain and pile.With (medicament all volatilizees) under the situation, insect in No. 1 storehouse (Wang Mixiang, flour mite, long angle ostomatid) density drops to " not finding insect " from original 32/kg paddy and promptly all kills at 30 ℃ of storehouse temperature, 29 ℃ of grain temperature, dosage, fumigation time homogeneous phase in above-mentioned two warehouses; Central Plains, No. 2 storehouses pest density is 30 a/kg paddy, after treatment, and in the grain heap, lower floor's pest density is between 10-20 head/kg paddy.Above-mentioned test shows, adopts the utility model to carry out insecticide and fumigates, and the grain heap in bulk big to grain heap, especially heaped measure in bulk, that the grain heap is high has remarkable insecticidal effect.In addition, the utility model also has following characteristics: one, and its adopts bamboo (as bamboo) to make, and compares with adopting plastic production, and it is low to have a cost, long service life, the advantage that has no side effect; Its two, it both can use aluminum phosphide tablet or pulvis, also can use to plastics have corrosiveness chloropicrin (as, the liquid chloropicrin is adsorbed in the husk).The utility model the most outstanding advantage when reality is used is: economical and practical.As, arrange 250 tons of storehouses, with 80 3 meters long, 20 2 meters long the utility model, only 1000 yuan of prices, and can repeatedly using.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is shown in Figure 1 along A-A line profile (amplification);

Fig. 3 is shown in Figure 1 along B-B line profile (amplification);

Fig. 4 is the stereogram of garden shown in Figure 1 cone blocking head.

Fig. 1 illustrates, bamboo drum is made by 2 general employing bamboos, the ring place gets through, make bamboo drum 2 internal run-throughs, generally speaking, the bamboo of certain-length is arranged, comparatively significantly stub end and little head end are all arranged, so the little head end of bamboo drum 2 is provided with garden cone blocking 1, mainly consider it is that this will help the operation of inserting down from garden cone blocking 1 position to the grain heap.In conjunction with Fig. 4 as seen, garden cone blocking 1 adopts a hardwood to make, and has bamboo nail hole 5 on the garden cone blocking 1, and bamboo nail 3 passes bamboo nail hole 5 garden cone blocking 1 and bamboo drum 2 are fixed.The fixing of garden cone blocking 1 and bamboo drum 2 also can use adhesive, in conjunction with Fig. 2 and Fig. 3, upper edge, the side axis direction of bamboo drum 2 is offered 4 promoting the circulation of qi holes 4 (under the big situation of diameter of bamboo drum 2, can establish 5 row or 6 row or multirow pores 4 more), adjacent two line spaces are identical, the center distance of adjacent two pores 4 is identical in every row, can select for use between 25～60mm.The aperture of pore 4 is 3～6mm.Should keep suitable distance between garden cone blocking 1 and the immediate pore 4, as about 10cm, in order to the splendid attire of fumigation medicament residue.The length of bamboo drum 2 generally can be made 5 meters with interior plurality of specifications.During use, select for use than grain stack height and hang down about 0.5 meter getting final product, then, be inserted into grain heap, from the bamboo drum 2 openings one end fumigation medicament of packing into, and with above-mentioned closure of openings, be inserted into the grain heap of nuzzling again, with film that the grain face is topped at last, thus finish the stifling whole operation of grain heap.

Claims (2)

1, a kind of bamboo inserting tube is characterized in that, comprises the bamboo drum (2) that inserts grain heap, internal run-through when using; Offer plural pore (4) on the side of bamboo drum (2); That the little head end of bamboo drum (2) is provided with is wooden, be convenient to the garden cone blocking head (1) inserted down in the grain heap.

2, bamboo inserting tube according to claim 1 is characterized in that, has the bamboo nail hole (5) that is used to use bamboo nail (3) that itself and bamboo drum (2) are interfixed on the described garden cone blocking head (1); The aperture of the pore (4) on the described bamboo drum (2) is 3～6mm, and pore (4) is provided with 4 row along the axis direction of bamboo drum (2), and adjacent two line spaces are identical, and the center distance of adjacent two pores (4) is identical in every row, is between 25～60mm.
