Abstract
The utility model discloses a cascade rapid soil nematode separating device, which comprises a separating sieve and at least four containers sequentially communicated with each other via pipelines. The distances from the bottom surfaces of all containers to a same horizontal plane are sequentially reduced according to the communication order of the containers, a water inlet is arranged on the container with the largest bottom surface distance, a water outlet is disposed at the bottom of the container with the smallest bottom surface distance, a sieve mesh is arranged between the container with the largest bottom surface distance and the adjacent container, and the top end of the pipeline between each two adjacent container is connected to the top of the container with the larger bottom surface distance. The cascade rapid soil nematode separating device has the advantages that soil suspension is transferred rapidly in the container, and the cascade rapid soil nematode separating device is less in loss during separation of soil nematode, high in recovery rate, convenient and flexible in operation, simple in structure and easy in assembly, disassembly and cleaning.
Description
Technical field
The utility model relates to agriculture monitoring technical field, relates in particular to a kind of staged soil nematodes fast separation device.
Background technology
Soil is the important place that nematode distributes, and has at least plant nematode that a stage of development carries out in soil and other soil free-living nematode of dwelling to be referred to as soil nematodes in soil in the life or the history of life.At present, the plant nematode harm in the soil nematodes is serious day by day, and production brings about great losses to world agriculture.In research work, the investigation of soil nematodes kind and accurate evaluation at first need tripping device fast and effectively.
Now, known soil nematodes separation method is the most effective with elutriation-mistake sieve method, its method of operating is: soil sample is placed the suitable bucket of size, the soil block of crumbing also is washed into soil suspending liquid with anxious current, leaves standstill after about 30 seconds supernatant is injected second bucket by 60 purpose bolters with suspending liquid, leaves standstill 30 seconds again, with soil suspending liquid again through 400 purpose sub-sieves, the filter residue that water fully washes on the sieve is removed soil particle, then filter residue is flushed in the beaker, promptly obtains nematode.
Suspending liquid in first bucket is poured into second bucket, and nematode is attached to a barrel wall easily, reduces the nematode recovery, needs Washing pail repeatedly, influences conventional efficient.Secondly, if soil property compares thickness, the soil suspended particle easily blocks screen cloth, and water can't ooze down, and need firmly pat sieve and make its mediation, time-consuming taking a lot of work, and the soil particle under the flushing easily stops up sewer pipe through long-term accumulation.At last, the nematode suspending liquid that the method obtains contains more foreign material, and influence is observed.
Summary of the invention
The utility model provides a kind of soil nematodes tripping device, has solved that traditional separation method is time-consuming, organic efficiency is not high, the problem of easy blocking pipe.
A kind of soil nematodes tripping device, comprise bolter and at least four containers that are communicated with by pipeline successively, all container bottoms reduce by the order that container is communicated with successively from the height of same surface level, wherein the container of bottom surface height maximum is provided with water inlet, the container bottom of bottom surface height minimum is provided with water delivering orifice, the container of bottom surface height maximum is adjacent in the pipeline between the container and is provided with screen cloth, and the top of pipeline connects the bigger container top of bottom surface height between adjacent two containers.
Above-mentioned tripping device also comprises the worktable that is used to place container, and table surface is provided with the step that quantity is no less than number of containers.
Described mesh size is 40～80 orders, most of foreign material interception can be lived.
The aperture of described bolter is greater than 400 orders, can keep nematode here.
Compared with prior art, the beneficial effects of the utility model are:
(1) only need to insert water under high pressure, just can in bolter, collect soil nematodes, simplified operation steps at the initial container of the utility model device, flexible to operation.
(2) soil suspending liquid transfer velocity in container is fast, and soil nematodes loss in detachment process is few, recovery height.
(3) the pipeline top connects the top of higher container, makes soil particle can fall to container bottom, avoids stopping up.
(4) this apparatus structure is simple, is easy to assembling, dismounting and cleaning.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Embodiment
As shown in Figure 1, a kind of soil nematodes tripping device comprises worktable 1, worktable 1 is provided with 4 continuous steps, has placed a container 2 on each step, and wherein the highest container is provided with water inlet, minimum container top is provided with water delivering orifice, and water delivering orifice connects rising pipe.
Adjacent two containers are communicated with by pipeline, and being provided with pore size in the pipeline between the wherein the highest container and the second high container is 60 purpose screen clothes 4.The top of each pipeline all connects the top of higher container, and so water just can overflow from pipeline, makes mud particles be deposited to container bottom.
Said apparatus also comprises a bolter 3, the water outlet that is mainly used in treating apparatus of bolter 3, and the separated and collected soil nematodes, its pore size is 400 orders, can certainly be higher than 400 orders.
During use, the pedotheque of fragmentation is put into the highest container, water inlet connects high pressure water generating device, after opening tap, water under high pressure fully stirs pedotheque, makes soil and nematode suspend, and flow in the next container from pipeline, screen cloth 4 can the bigger foreign material of the most of volumes of interception.
Water to all containers has all reached max cap., closes water under high pressure, leaves standstill 2min.Connection traffic device on water inlet pipe then, the controlled water flow flow slowly orders about suspension flow in the container to bolter 3 in, collects soil nematodes, and the water to all containers becomes clarification, stops collection.
Claims (4)
1. soil nematodes tripping device, comprise bolter and at least four containers that are communicated with by pipeline successively, it is characterized in that: all container bottoms reduce by the order that container is communicated with successively from the height of same surface level, wherein the container of bottom surface height maximum is provided with water inlet, the container bottom of bottom surface height minimum is provided with water delivering orifice, the container of bottom surface height maximum is adjacent in the pipeline between the container and is provided with screen cloth, and the top of pipeline connects the bigger container top of bottom surface height between adjacent two containers.
2. soil nematodes tripping device according to claim 1 is characterized in that, also comprises the worktable that is used to place container, and table surface is provided with the step that quantity is no less than number of containers.
3. soil nematodes tripping device according to claim 1 is characterized in that, the aperture of described screen cloth is 40～80 orders.
4. soil nematodes tripping device according to claim 1 is characterized in that, the aperture of described bolter is greater than 400 orders.
