Description
Technical Field
The utility model belongs to the technical field of pesticide residue technique and specifically relates to a pesticide residue detects extraction element for agricultural.
Background
Crops are various plants cultivated in agriculture. Including grain crops and economic crops (oil crops, vegetable crops, flowers, grasses and trees). In order to eliminate the damage of insect pests and reduce the growth influence of weeds on crops during crop planting, pesticides are generally sprayed, the pesticide consumption of agricultural products in China is high, the pesticide residues in the agricultural products are beyond the standard and the edible safety of consumers is affected due to unreasonable use of the substances, and the consumers are caused to have diseases and abnormal development in serious cases, even are directly poisoned and die.
For guaranteeing resident's dining table diet safety, crops need carry out short-term test to crops medicine residue before getting into the market, detect and go to the juice that needs to draw crops toward, but the juice volume of partial crops is less, need shift to inside the detection test tube after the extractor draws, but owing to the limited transfer back of extraction volume, have partial loss again, consequently need extract many times sometimes for satisfying the detection volume, waste time and energy, inefficiency.
Therefore, the utility model provides a pesticide residue detects extraction element for agricultural.
Disclosure of Invention
To agricultural among the prior art pesticide residue detects extraction element there is the extraction efficiency low, the big defect of transfer loss volume, a main aim at provides a agricultural is with pesticide residue detects extraction element.
In order to solve the technical problem, the utility model provides an agricultural pesticide residue detection and extraction device, which comprises a handle, an upper end cover, an extrusion cavity, an end cover, a test tube, a through hole, a filter screen, a pressing head and a screw rod; an opening at the upper end of the test tube is in threaded connection with an end cover, a hemispherical cavity is arranged at the upper end of the end cover, a through hole is formed in the lower end of the end cover, a filter screen is arranged at the lower end of the through hole, an upper end cover is in threaded connection with the upper end of the end cover, a hemispherical cavity is arranged at the lower end of the upper end cover, a spherical extrusion cavity is formed between the end covers of the upper end cover, the screw is in threaded connection with the upper end cover, a handle is installed at the top of the screw, and.
Preferably, the filter screen and the end cover are formed by integral injection molding.
Preferably, the radius of the hemispherical pressing head is equal to that of the spherical extrusion cavity.
Preferably, the upper end cover is made of transparent plastic materials.
Preferably, the aperture of the through hole is 0.2-0.5 times of the opening of the test tube.
The utility model has the advantages that:
the utility model discloses handle on the rotatory screw rod, under the press head squeezing action, the juice of formation can be in proper order via through-hole, the inside that the filter screen directly entered into the test tube, does not have the loss of transfer in-process, and draws the convenience, and convenient to use has simplified the extraction operation flow, has improved extraction efficiency.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is an overall front view structural diagram of the present invention.
Fig. 2 is a view showing the installation structure of the pressing head of the present invention.
In the figure, the position of the upper end of the main shaft,
1-handle, 2-upper end cover, 3-extrusion cavity, 4-end cover, 5-test tube, 6-through hole, 7-filter screen, 8-pressing head, 9-screw.
Detailed Description
The present invention will be further described with reference to the following drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
as shown in fig. 1 to 2, the agricultural pesticide residue detection and extraction device comprises a handle 1, an upper end cover 2, an extrusion cavity 3, an end cover 4, a test tube 5, a through hole 6, a filter screen 7, a pressing head 8 and a screw rod 9; test tube 5 upper end opening threaded connection has an end cover 4, end cover 4 upper end is equipped with a hemisphere cavity, end cover 4 lower extreme is equipped with a through-hole 6, through-hole 6 lower extreme is equipped with a filter screen 7, end cover 4 upper end threaded connection has an upper end cover 2, 2 lower extremes of upper end cover are equipped with a hemisphere cavity, form a spherical extrusion chamber 3 between upper end cover 2, the end cover 4, screw rod 9 and 2 threaded connection of upper end cover, a handle 1 is installed at screw rod 9 top, screw rod 9 lower extreme rigid coupling hemisphere press head 8.
Further, filter screen 7 and end cover 4 adopt the integral type to mould plastics and form, and overall structure intensity is high, and end cover 4 and test tube 5 are dismantled the separation conveniently, are difficult for appearing leaking.
Further, 8 radiuses of hemisphere pressing head and 3 radiuses in spherical extrusion chamber are equal, are convenient for extrude the juice of crops, improve extraction efficiency.
Further, the upper end cover 2 is made of transparent plastic materials, so that the space between the pressing head 8 and the extrusion cavity 3 and the extraction condition of crop juice can be observed conveniently, and the device is practical and convenient.
Furthermore, the aperture of the through hole 6 is 0.2-0.5 times of the opening of the test tube 5, and the situation that a large amount of crops are extruded to the position can not occur due to the small aperture of the through hole 6.
