Description

Technical Field

[0001] The utility model relates to an agricultural pesticide spraying device, belonging to the technical field of pesticide spraying. Background Art

[0002] Pesticide spraying is a crucial link in field planting. The effect of pesticide spraying directly affects the effect of pest control, and the effect of pest control directly affects the yield and quality of fruits and vegetables. When spraying, the pesticide must adhere to all the branches and leaves of the fruits and vegetables to achieve the best control effect. However, due to the large planting area, the past method of manually spraying pesticides is no longer applicable.

[0003] With the development of technology, many ways of replacing manual labor with machinery have emerged. Currently, one way is to tow a spraying device by a tractor to move forward on the soil between two rows of fruit trees. The existing spraying device of this kind can usually spray to both sides simultaneously. During the process of the tractor towing the spraying device forward, pesticides can be sprayed on the fruits and vegetables on both sides at one time.

[0004] However, modern agriculture is constantly developing towards large - area greenhouses and fields. The current spraying device can only spray the crops on both sides during one pass, with too low spraying efficiency and uneven spraying.

[0005] In summary, it is obvious that there are inconveniences and defects in the prior art in actual use, so it is necessary to improve. Content of the Utility Model

[0006] Aiming at the deficiencies in the background art, the utility model provides an agricultural pesticide spraying device, which can spray pesticides efficiently and evenly in large - area greenhouses and fields.

[0007] To solve the above - mentioned technical problems, the utility model adopts the following technical solutions:

[0008] An agricultural pesticide spraying device includes a spraying frame. Support rods are vertically installed on both sides of the spraying frame. A first spraying head is installed at the top of the support rod. The nozzle of the first spraying head faces outward. The middle position of the first spraying head is hinged at the top of the support rod. A push - pull rod is vertically and slidably installed on the spraying frame. The upper end of the push - pull rod is hinged with two connecting rod arms.

[0009] The upper end of one of the connecting rod arms is connected to the inner end of one of the first spraying heads, and the lower end is hinged to the upper end of the push - pull rod; the upper end of the other connecting rod arm is connected to the inner end of the other first spraying head, and the lower end is hinged to the upper end of the push - pull rod.

[0010] The push - pull rod reciprocates under the drive of a driving device.

[0011] Further, the upper end of the connecting rod arm is fixedly connected to the inner end of the first spray head by bolts.

[0012] Further, two guide posts are vertically fixed on the upper surface of the spray frame. The two support rods are arranged corresponding to the two guide posts one by one, and the lower end of the support rod is slidably mounted on the guide post.

[0013] Further, a horizontal fixing rod is fixed between the two support rods, and a screw rod is fixed at the lower end of the horizontal fixing rod. The screw rod is fixed on the spray frame by a nut.

[0014] Further, the driving device includes a driving motor fixed at the lower end of the spray frame. A driving disc is fixed on the driving shaft of the driving motor. A connecting rod is provided on the driving disc. One end of the connecting rod is hinged to the edge of the driving disc, and the other end of the connecting rod is hinged to the lower end of the push-pull rod.

[0015] Further, a spray pipe is installed on each side of the spray frame, and a plurality of second spray heads are arranged below the spray pipe.

[0016] Further, one end of the spray pipe close to the spray frame is hinged to the spray frame. A spray pipe fixing member is provided on the spray frame. An arc-shaped sliding groove is provided on the spray pipe fixing member. The spray pipe is fixed in the sliding groove of the spray pipe fixing member by an adjusting bolt.

[0017] Further, a medicine box is provided at the upper end of the spray frame. A spray pump is provided on one side of the medicine box. The spray pump is connected to the first spray head and the second spray head through pipelines.

[0018] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0019] The driving device pulls the push-pull rod to move up and down. The push-pull rod pulls the connecting rod arm to drive the first spray head to swing up and down. The first spray head can spray the fruits and vegetables in the distance. A spray pipe is installed on each side of the spray frame, and a plurality of second spray heads are arranged below the spray pipe. The second spray head can spray the fruits and vegetables nearby. Thus, the fruits and vegetables in the distance and nearby can be sprayed, the spraying efficiency is high, and the spraying is more uniform.
