Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The air-assisted orchard pesticide spraying device (hereinafter referred to as pesticide spraying device) shown in the attached figure 1 comprises a spraying assembly 1, a blower 2 and a pesticide tank 3;
the spraying assembly 1 comprises a spraying head cluster formed by a plurality of spraying heads 11, all the spraying heads 11 are arranged in order, and the spraying head cluster can spray a large-range area to be sprayed with a pesticide at the same time, so that the pesticide spraying efficiency is improved; as shown in fig. 2, each of the spray heads 11 is provided with a housing 12 and an atomizer 13; the shell 12 is internally provided with an air chamber, the air chamber and the atomizer 13 are respectively connected with the air blower 2 and the liquid medicine box 3, and a liquid sending pump is connected between the liquid medicine box 3 and the atomizer 13; the atomizer 13 is arranged in the air chamber, and the direction of the mist outlet of the atomizer 13 is consistent with the direction of the air outlet of the air chamber. A circle of annular gap is formed between the outer wall of the atomizer 13 and the inner wall of the shell 12, the airflow blown by the air blower 2 flows from the rear side of the atomizer 13 to the front side of the atomizer 13 through the annular gap, and is converged with the pesticide mist generated by the atomizer 13 and then sprayed out from the air outlet at the front end of the air cabin, and the airflow wraps the pesticide mist to advance, so that the pesticide mist can be sprayed to a higher place to realize pesticide spraying operation on higher fruit trees.
In order to ensure the spraying effect of the airflow and ensure the best medicine feeding effect of the sprayed airflow, the air cabin is cylindrical, the front side and the rear side of the air cabin are respectively provided with a narrowing structure, and the front side and the rear side of the air cabin are respectively provided with an airflow inlet and an airflow outlet; the atomizer 13 is cylindrical, has conical structures at the front side and the rear side, and is coaxially arranged with the air chamber; the atomizer 13 includes a liquid inlet pipe 14, and the liquid inlet pipe 14 extends in the axial direction of the atomizer 13 and penetrates through a side wall of the housing 12. Through above-mentioned structure, the air current is walked along the straight line in casing 12, and the windage of 13 rear ends of atomizer to the air current is little, and the annular gap that forms between atomizer 13 and the casing 12 is favorable to the air current to converge the wind-force performance of the air current of output after passing through, improves and send the medicine distance, and the annular gap can guarantee that air current and medicine fully converge in addition.
In order to make the spraying device adaptable to different spraying requirements, the spraying device further comprises density adjusting devices 15 for adjusting the distribution density of all the spraying heads 11. Through adjusting the distribution density to atomising head 11, the width of spouting the medicine of medicine device is different, to different fruit trees, can be to the density of distribution of adjusting atomising head 11, if to less and the fruit tree that the distribution distance is far away, can make atomising head 11 distribute densely a bit, and to great and the fruit tree that the distribution distance is nearer, can make atomising head 11 distribute sparsely a bit.
Specifically, all the spray heads 11 are arranged in two rows, the row spacing between the two rows of spray heads 11 can be adjusted, and the spacing between the spray heads 11 in each row can also be adjusted.
As shown in fig. 3, the density adjusting device 15 includes a device base 151, a rotating frame 152 is disposed on the device base 151 for each row of the spray heads 11, and the corresponding spray heads 11 are rotatably mounted on the rotating frame 152 through hard air pipes 154; the rotating frame 152 is rotatably installed with respect to the device base 151; the two groups of rotating frames 152 are fixedly provided with first synchronous gears 157, and the two first synchronous gears 157 are meshed with each other. Thus, the rotation of the rotary frame 152 can make the two rows of spray heads 11 move relatively in a dispersed manner or move relatively close to each other.
The rotating frame 152 is rotatably provided with a transmission shaft 153, and the transmission shaft 153 has a transmission relation with all the spray heads 11 on the rotating frame 152 so as to drive the spray heads 11 to perform diverging or converging motion.
A first bevel gear 155 is fixed on the hard air pipe 154 corresponding to each spray head 11, and a second bevel gear 156 is arranged on the transmission shaft 153 corresponding to each first bevel gear 155; the number of all the spray heads 11 in the same row is even, the two second bevel gears 156 on the same transmission shaft 153 are divided into two groups by taking the symmetrical center of the spray heads 11 in one row as a boundary, the small ends of the second bevel gears 156 in the same group face the same direction, and the small ends of the second bevel gears 156 in different groups face the opposite directions.
With the above structure, if all the spray heads 11 are gathered together in the initial state, when the transmission shaft 153 rotates, and the division is taken as the center, the spray heads 11 in the same row are divided into two groups, which are respectively diverged and inclined towards two sides, so that the spray heads 11 in the same row are gradually diverged. Preferably, in order to make the air outlets of the spray heads 11 oriented differently after the spray heads 11 are spread, the transmission ratios of the hard air pipe 154 corresponding to each spray head 11 on the same transmission shaft 153 and the direct bevel gear set of the transmission shaft 153 (i.e. the corresponding first bevel gear 155 and second bevel gear 156) are all different, and the transmission ratio between the transmission shaft 153 and the hard air tube 154 near the edge position is smaller than that between it and the hard air tube 154 near the middle position, and thus, when the transmission shaft 153 rotates at the same angle, the hard air tube 154 near the edge rotates at a larger angle, the hard air tube 154 near the middle rotates at a smaller angle, so that the spray heads 11 on the same drive shaft 153 can be fully dispersed, not only the straight distance is increased, the relative angle of the spraying direction of each spray head 11 is increased, so that the coverage area of the spray can be enlarged.
Preferably, the rotating frame 152 is coaxially disposed with the transmission shafts 153, and the two transmission shafts 153 corresponding to the two rows of spray heads 11 are respectively fixed with a second synchronizing gear 158, and the two second synchronizing gears 158 are engaged with each other, so that the two transmission shafts 153 can synchronously rotate in opposite directions at a constant speed. Fig. 4 shows the spray assembly 1 after the spray head has been spread.
In addition, a first power gear 161 is mounted on one of the rotating frames 152, a second power gear 162 is mounted on the corresponding transmission shaft 153 of the rotating frame 152, a gearbox 163 is disposed between the first power gear 161 and the second power gear 162, and one of the rotating frames 152 is in driving connection with a density adjusting motor 164. Through the structure, the rotation of the rotating frame 152 and the rotation of the hard air pipe 154 on the rotating frame 152 can be linked by controlling the rotation of the density adjusting motor 164, and the driving cost is saved.
According to the air-assisted orchard pesticide spraying device, the air flow provided by the air blower can wrap pesticide mist and spray through the atomizing spray heads by arranging the air-assisted atomizing spray heads and the air blower, so that the pesticide mist can be sprayed to a higher crown sprayer and the pesticide mist can be sprayed to all parts of a plant canopy by virtue of the strong air flow of the tail end nozzle, the air flow is helpful for improving the range of the orchard sprayer, assisting the pesticide mist to penetrate through a dense canopy, promoting the blades to turn over and improving the blade attachment rate.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
