[0023] The utility model provides a kind of agricultural plant protection pesticide spraying device as Figures 1 to 5 As shown in the drawing, including the hydraulic cylinder 2 of being fixed on the agricultural vehicle body 1 of agricultural vehicle, water pump 6 and liquid medicine tank 7.

[0024] The telescopic shaft of hydraulic cylinder 2 is vertically upwards and is fixedly connected mounting seat 4, and mounting seat 4 is fixedly provided with liquid injection pipe 3. Liquid injection pipe 3 is arranged along horizontal direction, and the bottom of liquid injection pipe 3 is fixedly installed with multiple spray heads, and multiple spray heads are downward to ground and are arranged in line along the length direction of liquid injection pipe 3.

[0025] A liquid passage 14 is formed in the mounting base 4 in the vertical direction, and the liquid spray pipe 3 is located at the bottom of the liquid passage 14 and communicates with the liquid passage 14. A horizontal filter plate 12 is arranged in the liquid passage 14, and the filter plate 12 is detachably fixedly connected with the mounting base 4. Specifically, the detachable fixed connection mode includes but is not limited to the use of screws or bolts.

[0026] A connecting pipe 5 is fixedly arranged between the mounting base 4 and the water pump 6, and the connecting pipe 5 is a hose. One end of the connecting pipe 5 penetrates into the mounting base 4 and communicates with the liquid passage 14, and the end is located above the filter plate 12. The other end of the connecting pipe 5 communicates with the liquid outlet of the water pump 6, and the liquid inlet of the water pump 6 communicates with the liquid tank 7.

[0027] A dismounting opening is formed in the top of the mounting base 4, and the dismounting opening communicates with the liquid passage 14. A sealing cover 10 is detachably mounted in the dismounting opening. Specifically, the detachable mounting mode includes but is not limited to the use of threaded sealing connection, that is, the sealing cover 10 is threadedly sealingly connected with the mounting base 4.

[0028] The filter plate 12 is fixedly mounted in the liquid passage 14, and a striking rod 8 is vertically arranged in the sealing cover 10. A corrosion-resistant rubber pad is fixedly arranged at the bottom of the striking rod 8. The striking rod 8 is drivingly matched with the liquid flowing out of the connecting pipe 5 through a transmission mechanism, and is used to drive the striking rod 8 to collide with the filter plate 12 through the transmission mechanism, so as to shake out the impurities in the filter holes of the filter plate 12.

[0029] The striking rod 8 penetrates upwardly through the sealing cover 10 and sealingly slides with the sealing cover 10.

[0030] The transmission mechanism includes a fan blade 11, which is mounted in the liquid passage 14 and rotationally connected with the bottom of the sealing cover 10. The fan blade 11 is sleeved on the striking rod 8 and slidingly matched with the striking rod 8. The fan blade 11 is drivingly matched with the liquid flowing out of the connecting pipe 5 and the striking rod 8.

[0031] A transmission block 9 is fixedly arranged at the top of the sealing cover 10. A reciprocating threaded section is formed on the striking rod 8. The rod body where the reciprocating threaded section is located penetrates through the transmission block 9 and is threadedly connected with the transmission block 9.

[0032] The striking rod 8, the reciprocating threaded section, the ball and the transmission block 9 jointly form a ball screw pair.

[0033] A collection block 13 is rotationally mounted on the top end surface, i.e. the filtering surface, of the filter plate 12. The collection block 13 is slidingly contacted with the top end surface, i.e. the filtering surface, of the filter plate 12. Specifically, the collection block 13 is in a vortex shape, and the receiving groove for receiving impurities is formed on the outer spiral surface of the collection block 13 along the contour of the collection block 13. A collection box is fixedly arranged at the end of the collection block 13 away from the vortex center, and the collection box communicates with the receiving groove.

[0034] The impact rod 8 penetrates the vortex center of the collecting block 13, and the collecting block 13 is in both sliding fit and transmission fit with the impact rod 8.

[0035] A transmission groove is formed in the impact rod 8 in the vertical direction, and two connecting blocks are limitedly and slidably installed in the transmission groove. One of the connecting blocks is fixedly connected with the collecting block 13, and the other connecting block is fixedly connected with the fan blade 11.

[0036] Working principle: when the device is used for pesticide spraying in the process of agricultural plant protection, the prepared pesticide is first filled into the liquid tank 7. Then the water pump 6 is started, and the pesticide in the liquid tank 7 is pumped out. Then the liquid is introduced into the liquid passage 14 of the mounting seat 4 through the connecting pipe 5, and the liquid in the liquid passage 14 is filtered by the filter plate 12 and then introduced into the liquid spraying pipe 3. The liquid in the liquid spraying pipe 3 is sprayed onto the agricultural plants by the spray head.

[0037] When the liquid passes through the liquid passage 14, the liquid impacts the fan blade 11. The fan blade 11 drives the impact rod 8 to rotate through the corresponding connecting block. Since the reciprocating threaded segment on the impact rod 8 is in threaded connection with the transmission block 9, the impact rod 8 rotates and slides up and down at the same time. When the impact rod 8 slides down, it gradually approaches the filter plate 12 and finally impacts the filter plate 12. During the impact process, the impact rod 8 extrudes the corrosion-resistant rubber pad, and the corrosion-resistant rubber pad transmits the impact force to the filter plate 12. At this time, the filter plate 12 vibrates, so that the impurities in the filter holes are vibrated out under the action of inertial force. When the impact rod 8 slides up, the bottom end does not deviate from the collecting block 13.

[0038] During the rotation of the impact rod 8, the collecting block 13 is rotated through the corresponding connecting block. The rotation direction of the collecting block 13 corresponds to the vortex direction of the collecting block 13. During the rotation of the collecting block 13, the impurities on the filter plate 12 are collected in the receiving groove. At the same time, under the action of centrifugal force, the impurities gradually move along the collecting block 13 to the collecting box and are concentratedly collected.

[0039] In this embodiment, the rotation direction of the impact rod 8 is opposite to the locking direction of the sealing cover 10.

[0040] After the liquid spraying is completed, the water pump 6 is turned off. Then, after the liquid in the liquid spraying pipe 3 is emptied, the transmission block 9 is twisted, and the transmission block 9 drives the sealing cover 10 to rotate. The sealing cover 10 is gradually detached from the mounting seat 4, and at the same time, the impact rod 8 gradually deviates from the collecting block 13. When the sealing cover 10 is detached from the mounting seat 4, and the impact rod 8 is extracted from the liquid passage 14, the filter plate 12 is detached from the mounting seat 4 by twisting the bolt or screw, and the filter plate 12 and the collecting block 13 are taken out from the liquid passage 14 for flushing. After flushing, reassemble for the next liquid spraying.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
