A pesticide sprinkler for hot pepper is planted, as shown in fig. 1 and fig. 2, including backup pad 17 and the stay tube 13 of fixing on backup pad 17, the lower part fixedly connected with of backup pad 17 has a plurality of current telescopic shafts 18, and in this embodiment, stay tube 13 is L, and the horizontal segment threaded connection of stay tube 13 has joint 19, and joint 19 is last to open has the logical groove 191 with stay tube 13 intercommunication, and joint 19 is last to have a plurality of retaining members 192 along its circumference threaded connection, and retaining member 192 is the bolt.

The vertical section of stay tube 13 rotates and is connected with spraying bucket 11, and backup pad 17 is provided with drive unit, and drive unit includes the motor 16 of bolt fastening on backup pad 17, is fixed with main gear 15 on the output shaft of motor 16 coaxial, and main gear 15 meshing has the slave gear 20 with spraying bucket 11 coaxial fixed connection.

The spraying barrel 11 is provided with a plurality of through holes 12, the through holes 12 are uniformly distributed along the vertical direction of the spraying barrel 11, the spraying pipe 23 is horizontally and dynamically connected in the through holes 12, one side of the spraying pipe 23 is provided with a plurality of spraying holes 25, the other side of the spraying pipe 23 is horizontally and slidingly connected with a supporting shaft 21 rotationally connected with the supporting pipe 13, an elastic piece fixedly connected with the spraying pipe 23 is fixed on the supporting shaft 21 and is a spring 22, the spraying pipe 23 is provided with a liquid inlet 26, the liquid inlet 26 is communicated with a spraying cavity 24 of the spraying pipe 23 and the spraying barrel 11, in an initial state, the supporting shaft 21 is used for sealing the liquid inlet 26, and the diameter of the spraying cavity 24 in the spraying pipe 23, which is close to one end of the supporting shaft 21, is larger than the diameter of one end far away from the supporting shaft 21, namely the spraying cavity 24 of the spraying pipe 23 is trapezoid.

The application method of the pesticide spraying device for pepper planting comprises the following steps:

s1, adjusting the height of the device through the telescopic shaft 18 to adapt to different height requirements, such as 10cm, 20cm and the like. The pipe is then extended into the joint 19, and then locked to the joint 19 by the locking member 192, and the pipe is communicated with the centrifugal pump, and the pesticide is fed into the spray barrel 11 through the centrifugal pump and the support pipe 13.

S2, starting the motor 16, enabling the rotating speed of the motor 16 to reach 300r/S, enabling the motor 16 to drive the main gear 15 to rotate, enabling the main gear 15 to drive the auxiliary gear 20 to rotate, enabling the auxiliary gear 20 to drive the spraying barrel 11 to rotate, enabling the spraying barrel 11 to generate centrifugal motion when the spraying barrel 11 rotates, enabling the spraying pipe 23 to move towards the outside of the spraying barrel 11 until the liquid inlet 26 enables the spraying barrel 11 to be communicated with the spraying pipe 23, enabling pesticides to be sprayed out from the spraying holes 25 to form annular spraying under the action of hydraulic pressure and the centrifugal action, enabling the flowing area of the pesticides to be gradually reduced due to the fact that the spraying cavity 24 is trapezoid, improving the flowing speed of the pesticides, and achieving the purpose of wind prevention to a certain extent (preventing the pesticides from flowing reversely under the action of wind to a certain extent). In the process of rotating the spraying barrel 11, the supporting shaft 21 is driven to synchronously rotate through the spraying pipe 23, and the spraying pipe 23 and the supporting shaft 21 stir the pesticide in the spraying barrel 11 so as to improve the mixing effect of the pesticide.

And S3, when spraying is stopped, namely the motor 16 is turned off, the spraying barrel 11 stops rotating, the spring 22 drives the spraying pipe 23 to reset, at the moment, the supporting shaft 21 and the spraying pipe 23 relatively move, and under the extrusion action of the supporting shaft 21, the pesticide in the spraying pipe 23 is extruded, so that pesticide residues in the spraying pipe 23 are reduced. Meanwhile, the liquid inlet 26 is closed by the support shaft 21, and the pesticide in the spraying tub 11 stops entering into the spraying pipe 23, thus blocking the flow of the pesticide to avoid the waste of the pesticide. Because spray barrel 11 and stay tube 13 are all sealed, can not cause the leakage of pesticide when the device removes, can not drip to the outside of spray barrel 11 promptly, also can not directly drip in the soil, play certain guard action.

Embodiment two:

the difference between the second embodiment and the first embodiment is that, as shown in fig. 3, a sealing shaft 31 is vertically slidably connected in the supporting shaft 21, the sealing shaft 31 penetrates through the spraying barrel 11, graduation marks 32 are opened on the sealing shaft 31, and the sealing shaft 31 is used for sealing the liquid outlet 14. A baffle plate 33 is fixed on the supporting shaft 21 through screws, the baffle plate 33 is used for closing the through hole 12, and the baffle plate 33 is vertically matched with the spraying barrel 11 in a sliding manner.

The application method in the embodiment comprises the following steps:

s1, sliding the sealing shaft 31 downwards in advance, observing the downwards sliding distance of the sealing shaft 31 through the scale marks 32, so that the sealing shaft 31 seals part of the liquid outlet holes 14, the communication area between the supporting tube 13 and the spraying barrel 11 is reduced, and the flow of pesticide entering the spraying barrel 11 is reduced. Meanwhile, in the process of downwards sliding of the supporting shaft 21, the baffle 33 is driven to seal the through hole 12, at the moment, the spraying pipe 23 cannot extend out of the through hole 12, the area of the spraying barrel 11 communicated with the outside is reduced, and the flow of pesticide sprayed from the spraying barrel 11 is reduced, so that the purpose of adjusting the flow of pesticide sprayed from the spraying barrel 11 is achieved.

S2, adjusting the length of the telescopic shaft 18 until the spray barrel 11 reaches a desired position, for example: above the pepper plant or below the pepper plant.

And S3, starting the motor 16, and feeding the pesticide into the supporting tube 13 through the centrifugal pump. Since the outlet hole 14 is partially closed, the flow rate of the pesticide into the spray barrel 11 is reduced. When the motor 16 rotates the spray tub 11, since the through holes 12 are closed, the number of the spray pipes 23 protruding from the through holes 12 is reduced. In the centrifugal rotation process of the spraying barrel 11, at this time, the spraying pipe 23 which is not sealed is communicated with the spraying barrel 11, at this time, the flow rate of the pesticide sprayed from the spraying barrel 11 is reduced, and the flow rate of the pesticide is accelerated under the condition that the acting force is unchanged due to the reduction of the flow area of the pesticide, so that the spraying area of the pesticide is enlarged.

In this embodiment, the area of spraying the pesticide is enlarged and the pesticide spraying efficiency is improved by means of flow regulation.
