Description
Technical Field
The invention relates to the technical field of pesticide performance testing, in particular to a device for detecting the retention amount of pesticide liquid fog drops.
Background
The use of pesticides is essential in modern agriculture; the most common method for using pesticides in China is to spray pesticides in fields by using different spraying devices, and in recent years, a spraying mode of spraying by using an unmanned aerial vehicle also appears; the retention capacities of pesticide liquid with different physical and chemical properties on the surfaces of different plants are different; because the retention capacity of various plants to different pesticide liquid medicines is not clear, the liquid medicine sprayed by the plants often runs off due to the fact that the amount of the liquid medicine exceeds the maximum retention capacity of the surface of the target plant, on one hand, waste is caused, and on the other hand, the environment is polluted. Therefore, the detention capability of different pesticide liquid on the surface of the target plant needs to be known, so that a basis is provided for controlling the field liquid dosage or improving the detention capability of the liquid on the surface of the target plant by changing the physicochemical property of the liquid.
The conventional retention capacity detection mode is that plant leaves are directly immersed in liquid medicine, and the liquid medicine retention amount of the leaves in unit area in a static state is measured after weighing, but is different from the liquid medicine retention amount of the leaves in a dynamic state during spraying. Direct immersion of the leaves in the solution is a process of replacing the solid-liquid interface with the solid-gas interface, and mist drops on the leaves during spraying and wetting are processes of changing the liquid-gas interface and the solid-gas interface into the solid-liquid interface. Secondly, most of the chemical solutions used for spraying contain a surfactant, which has the property of adsorbing at the interface. During spraying, a large amount of fine fog drops are formed in the liquid medicine, a new liquid-air interface expands rapidly, surfactant molecules on the liquid-air interface are diluted greatly, the surface tension of the liquid medicine rises, time is needed for the surfactant molecules in the liquid medicine to transfer to the new liquid-air interface, and the fog drops fall onto the leaf surface, so that the surface tension of the fog drops at the moment of contacting the leaf is too high to wet and spread on the leaf surface, the retention of the liquid medicine on the leaf surface is influenced, and the actual situation of the field can be reflected by the retention of the liquid medicine on the leaf in a spraying state. If the leaves are directly immersed into the liquid medicine, the surfactant in the liquid medicine is easier to transfer to a new interface, and the leaves are easier to wet, so that the retention amount of the liquid medicine on the surfaces of the leaves is larger, and the retention capacity of the liquid medicine on the surfaces of target plants under field conditions cannot be correctly reflected.
As a result of the search, patent publication No. CN102116668A discloses a metering device for change in retention of a spray chemical on the surface of a plant leaf, comprising: glass cover, electronic balance, carry the leaf platform bracing piece, carry the leaf platform base, tubaeform sleeve pipe, electronic balance arranges inside the glass cover, carry the leaf platform base and place on electronic balance, the aperture has been seted up at the glass cover top, it passes this aperture and inserts and carries the leaf platform base and can support to carry the leaf platform bracing piece, carry the leaf platform and be fixed in the top of carrying the leaf platform bracing piece, tubaeform sleeve buckle arranges glass cover upper surface and cover outside carrying the leaf platform bracing piece in, its inner wall and carry the loose cooperation of leaf platform bracing piece, the scheme disclosed in this patent has improved the accuracy that the spraying liquid medicine carries out the measurement at plant leaf blade surface retention change to a certain extent, but detect at present that the balance of leaf surface liquid medicine fog drip retention is mostly ten thousand minutes, it is not only high accuracy and comparatively sensitive, tiny change all can exert an influence to monitoring data in the environment, lead to the unable accurate data of measuring of balance, it is a very violent process to ten thousand minutes to the plant leaf blade very violent process after spraying medicine, often can take place very violent shakiness of the shakiness, so be similar to the technical balance, therefore the very big stability of waiting for the plant leaf blade to the long direct stability of waiting for the plant and waiting for the long leaf blade, the long time of waiting for the plant.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments; moreover, the embodiments are not independent, and can be combined with each other according to requirements, so that a better effect is achieved. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
The detailed description and exemplary embodiments of the invention will be better understood when read in conjunction with the appended drawings, where the elements and features of the invention are identified by reference numerals.
The pesticide liquid droplet holding capacity detection device comprises a detection box body 110, a ten-thousandth scale 210 and a bending rod 220, wherein the ten-thousandth scale 210 is arranged at the bottom of the detection box body 110, the ten-thousandth scale 210 is not in contact with the detection box body 110, the bottom end of the bending rod 220 is fixed on the ten-thousandth scale 210, the bottom end of the bending rod 220 upwards extends to the upper part of the detection box body 110 along the side edge of the detection box body 110, and the top end of the bending rod 220 is correspondingly arranged above the detection box body 110; a through hole 114 is formed in the top plate 111 of the detection box 110, a hanging member 301 passing through the through hole 114 is downwardly disposed at the top end of the bending rod 220, a mist droplet holding plate 300 is hung at one end of the hanging member 301 away from the bending rod 220, and the mist droplet holding plate 300 is disposed below the chemical solution spray head 400 in the detection box 110. The hanger 301 is linear and suspends the mist trap 300.
In the process of detecting the pesticide liquid fog drop retention amount, the liquid to be detected needs to be sprayed onto the fog drop retention plate 300 in a fog drop state by using the liquid spray head 400, spraying is stopped after a preset time, the fog drop retention plate 300 with the liquid pesticide fog drops distributed on the surface is weighed by using the universal scale 210, and the increased mass of the fog drop retention plate 300 at the weighing position is the liquid pesticide amount retained on the surface of the fog drop retention plate 300. As is well known, the accuracy of the ten-thousandth scale 210 is high on one hand, and the readings of the ten-thousandth scale 210 are sensitive on the other hand, if an object on the ten-thousandth scale 210 moves slightly, the acceleration generated by the object can influence the readings of the ten-thousandth scale 210.
When the pesticide liquid droplet retention amount is detected, the hanging piece 301 for hanging the droplet retention plate 300 is linear, so that on one hand, the inaccuracy of final retention amount data caused by the fact that the droplets are attached to the linear hanging piece 301 can be avoided, and on the other hand, the droplet retention plate 300 can move, so that the spraying state of the leaves in reality can be simulated more realistically. The problem caused by the above is that the liquid medicine nozzle 400 sprays the liquid medicine to be detected onto the droplet retention plate 300 in a droplet state, which inevitably causes the movement of the droplet retention plate 300, and if the droplet retention plate 300 is directly connected with the ten-thousandth balance 210, the acceleration generated by the movement of the droplet retention plate 300 causes the fluctuation of the number indicated by the ten-thousandth balance 210, and if the problem is not solved, the efficiency and the accuracy of the experimental data detection are greatly influenced; and it is artificially difficult to suppress the movement of the mist droplet holding plate 300.
In order to solve the above technical problem, the applicant adopts the technical solution of the present embodiment, and the universal scale 210 is disposed at the bottom of the detection box 110, and is connected to the upper side of the detection box 110 through the bending rod 220 to hang the mist retaining plate 300, and then performs the measurement. When examining pesticide liquid medicine droplet holding capacity, hang through bending pole 220 to droplet holding board 300 on the one hand and weigh and can avoid pesticide liquid medicine droplet spraying process to produce the influence to weighing the process, droplet holding board 300 that on the other hand hung takes place to rock, but because the setting of bending pole 220, droplet holding board 300 rocks and subducts gradually at the in-process by the transmission of bending pole 220, make this rock can not directly influence the weighing result of ten thousand minutes title 210, thereby reduce the time of waiting for ten thousand title 210 indications to stabilize greatly, improve and detect the precision.
More specifically, the bending rod 220 includes a fixing portion 221, a bending side portion 224 and a top end hanging portion 225, the fixing portion 221 is fixedly arranged on the ten-thousandth scale 210, and the fixing portion 221 can be fixed on the ten-thousandth scale 210 by glue and/or screws; the top end hanging portion 225 is provided above the detection chamber 110 to hang the mist retaining plate 300, and is connected to the side portion fixing portion 221 of the detection chamber 110 and the top end hanging portion 225 by a bent side portion 224.

And the length of the weight 223 is L, the distance from the connecting part between the hanging piece 301 and the weight 223 to the side of the weight 223 close to the bending rod 220 is L, the L = kL, wherein k is more than or equal to 0.20 and less than or equal to 0.45, and the k can be 0.20 or 0.25 or 0.30 or 0.40 or 0.45, and the stability of the weight 223 can be further improved by arranging the connecting part on the weight 223 close to the bending rod 220, so that the suspended fog drip holding plate 300 is more difficult to shake the weight 223. The distance from the gravity center of the weight 223 to the bending rod 220 can be larger than the distance from the ten-thousandth scale 210 to the bending rod 220, so that the overall stability of the bending rod 220 is facilitated, and the bending rod 220 is further prevented from shaking.
