Specifically, when liquid fertilizer can be sprayed out from the first spray head 104 or emulsifiable pesticide can be sprayed out from the second spray head 105, all the electromagnetic blocks 308 on the control mechanism 201 are energized, the energized electromagnetic blocks 308 generate magnetic force, under the attraction of the magnetic force, the iron block 401 is attracted to the electromagnetic blocks 308 (at this time, the elastic spring 402 is in a stretched state), and in the moving process of the iron block 401, the iron block 401 pulls the connecting rod 309 to move, so that the plug 307 is pulled to slide along the outer side of the sliding groove 306, so that the plug 307 no longer blocks the through-flow hole 403, the liquid fertilizer can flow into the first spray head 104 from the first supply pipe 106, and the emulsifiable pesticide can flow into the second spray head 105 from the second supply pipe 107; on the contrary, when need not to make liquid fertilizer can be by first shower nozzle 104 blowout or cream pesticide can be by second shower nozzle 105 blowout, make all electromagnetism pieces 308 outage in the control, electromagnetism piece 308 after the outage can lose magnetic force, the elasticity spring 402 that is in under the state of being stretched this moment can reset under the effect of resilience force, thereby pulling iron plate 401 resets, thereby make and drive end cap 307 and reset, thereby make end cap 307 block up the through-flow hole 403 again, make liquid fertilizer can not pass through first feed, make cream pesticide can not pass through second feed pipe 107. In addition, when the spraying amount of the first spray head 104 or the second spray head 105 needs to be controlled, the on-off number of the electromagnetic blocks 308 only needs to be controlled, specifically, preferably, the sliding grooves 306 in the control mechanism 201 are arranged into four groups, when only one-half spraying amount is needed, two of the magnetic blocks in the control mechanism 201 are electrified and the other two magnetic blocks are not electrified, the liquid fertilizer or the missible oil pesticide can only flow out of two of the through-flow holes 403 in the control mechanism 201 but can not flow out of the other two through-flow holes 403, and thus, the first spray head 104 or the second spray head 105 has only one-half spraying amount. Similarly, when only one-fourth of the spraying amount is needed, one of the electromagnetic blocks 308 in the control mechanism 201 is powered on, and the other three electromagnetic blocks 308 are powered off. In this way, the spraying amount of the first spray head 104 and the second spray head 105 can be adjusted by the control mechanism 201, and the control mechanism 201 has a simple overall structure, is easy to control, and has low manufacturing cost and a wider application range.
As shown in fig. 4 and 5, a first connecting block 404 is connected in the first shell base 304 in a matching manner, a first threaded connection hole 405 is formed in the first connecting block 404, a second connecting block 406 is connected in the second shell base 305 in a matching manner, and a second threaded connection hole 407 is formed in the second connecting block 406.
It should be noted that, the control mechanism 201 can be connected to the first feeding pipe and the second feeding pipe through the first thread screwing hole 405 and the second thread screwing hole 407, and the installation process is simple and easy to detach.
The invention also discloses a control method of the fertilizer and pesticide preparation device for flue-cured tobacco planting, which is applied to any one fertilizer and pesticide preparation device for flue-cured tobacco planting, and comprises the following steps:
acquiring image information of a jet flow region through an optical camera;
extracting parameter information of an emergent flow area based on the image information, wherein the parameter information comprises contour information of the emergent flow area;
extracting first coordinate values of a transverse jet flow region and a node closest to a jet flow stagnation point in a radial jet flow region based on the parameter information;
extracting a second coordinate value of a node which is the transverse jet flow region and the radial jet flow region farthest from the jet flow stagnation point based on the parameter information;
calculating an emergent flow loop quantity coefficient based on the first coordinate value and the second coordinate value;
and adjusting the spraying amount of the first spray head and the second spray head in real time based on the jet circulation coefficient.
Further, in a preferred embodiment of the present invention, the adjusting of the spraying amount of the first nozzle and the second nozzle in real time based on the circulation coefficient of the jet flow specifically includes the following steps:
if the jet circulation coefficient is greater than or equal to 1, reducing the spraying amount of the first spray head and the second spray head;
if the jet flow circulation coefficient is larger than 0 and smaller than 1, the spraying amount of the first spray head and the second spray head is not adjusted;
and if the jet circulation coefficient is less than or equal to 0, the spraying amount of the first spray head and the second spray head is increased.
It should be noted that the jet circulation coefficient is a physical quantity used for representing the characteristics of a vortex structure of a jet field, and can macroscopically represent the distribution condition of the jet contour after the missible oil pesticide and the liquid fertilizer are oppositely collided, generally speaking, the more the jet contour tends to be circular, the better the distribution uniformity of the contour after the missible oil pesticide and the liquid fertilizer are oppositely collided is, namely the better the mixing effect of the missible oil pesticide and the liquid fertilizer is, and the calculation formula of the jet circulation coefficient is as follows:
wherein R is e Representing the circulation coefficient of the jet flow; n represents the number of nodes on the jet region; i represents the ith node on the jet region; t is n Representing the coordinate value of the nearest node of the transverse jet flow region from the jet flow stagnation point; t is n+1 Representing the coordinate value of a node which is farthest away from the jet stagnation point in the transverse jet area; p is n A coordinate value representing a nearest node of the transverse jet flow region from the jet flow stagnation point; p n+1 And the coordinate value represents the node of the transverse jet flow region farthest from the jet flow stagnation point.
It should be noted that the distribution of the jet flow profile in the jet flow area can reflect the mixing degree of the missible oil pesticide and the liquid fertilizer. If the jet circulation index of the jet area is larger than or equal to 1 when the missible oil pesticide and the liquid fertilizer are oppositely impacted, the kinetic energy carried by the missible oil pesticide and the liquid fertilizer during the opposite impact is overlarge, and after the missible oil pesticide and the liquid fertilizer are oppositely impacted at the jet stagnation point to change the direction, the higher flow velocity is still kept in the transverse jet area and the radial jet area, so that the impact friction time of the missible oil pesticide and the liquid fertilizer is too short, the mass transfer time is too short, the mixing effect of the missible oil pesticide and the liquid fertilizer can be reduced, and at the moment, the spraying amount of the first spray head and the second spray head needs to be increased through a control mechanism; if the jet circulation index of the jet area is less than or equal to 0 when the missible oil pesticide and the liquid fertilizer are oppositely impacted, the kinetic energy carried by the missible oil pesticide and the liquid fertilizer during the opposite impact is too small, so that the dispersion degree of the missible oil pesticide and the liquid fertilizer after the impact is lower, the distribution range of the impacted jet area is too small, the mixing efficiency of the missible oil pesticide and the liquid fertilizer is influenced, and at the moment, the spraying amount of the first spray head and the second spray head needs to be reduced through a control mechanism; and if the jet circulation coefficient is more than 0 and less than 1, the mixing effect and efficiency of the missible oil pesticide and the liquid fertilizer are better, and the spraying amount of the first spray head and the second spray head does not need to be adjusted.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
