Description

Technical Field

[0001] The invention relates to the field of agricultural planting, and in particular to an agricultural planting pest prevention spray device. Background Art

[0002] Crop diseases and insect pests are one of the main agricultural disasters in my country. They are characterized by many types, great impact, and frequent outbreaks. The scope and severity of their occurrence often cause significant losses to my country's national economy, especially agricultural production. The following types of diseases and insect pests are common in my country's crops: rice planthoppers, powdery mildew, corn borers, cotton bollworms, wheat rust, cotton aphids, rice sheath blight, rice blast, wheat aphids, wheat red spiders, locusts, wheat ergot, etc., which have become major diseases and insect pests that seriously affect my country's agricultural production. With the development of society, the application of agricultural pest control has become more and more extensive. Therefore, the demand for agricultural pest control sprayers is growing.

[0003] Most agricultural pest control spray devices on the market can only spray pesticides from above the crops when in use. Because some crops have lush branches and leaves, high planting density, and some crops have wide leaves, the pesticides sprayed from above are only sprayed on the upper surface of the crops, and the drugs cannot be sprayed on the bottom of the crops. Moreover, because the leaves of crops are wide, even if the drugs are sprayed on the leaves, they cannot be sprayed on the lower surface of the leaves. In this way, the pests hiding under the leaves cannot be killed, affecting the effect of pest control and pest killing.

[0018] The hydraulic cylinder 6 is connected to an external hydraulic station pipeline through a pipeline.

[0019] Working principle: When the present invention is used, the device is connected to a tractor by a traction rod 3, and the device is pulled to the farmland by the tractor. Then, the spacing of the plurality of first water pipes 19 is adjusted according to the spacing of the ridges, so that the spacing of the plurality of first water pipes 19 is equal to the spacing of the ridges. The first locking bolt 13 is loosened during the adjustment, so that the spacing of two adjacent first water pipes 19 can be adjusted by sliding the first square tube 12. After the spacing is adjusted, the first locking bolt 13 is tightened. After the spacing is adjusted, the device is pulled to start spraying the crops. When the device enters the farmland, each first water pipe 19 is matched with a ridge, and the telescopic end of the hydraulic cylinder 6 is controlled to extend. At this time, the hydraulic cylinder 6 pushes the cross bar 8, and when the cross bar 8 is pushed, it is connected to the cross bar 8. The plate 9 rotates the shaft 10, and when the shaft 10 rotates, it synchronously drives the first square rod 11 to rotate. When the first square rod 11 rotates, it drives the first water pipe 19 to rotate, so that the second roller 21 at the side end of the first water pipe 19 will fall into the ditch. When the hydraulic cylinder 6 continues to push, the semicircular guide rod 15 slides with the arc sliding cylinder 16, and the arc sliding cylinder 16 squeezes the spring 18. When the spring 18 is squeezed, the hydraulic cylinder 6 stops pushing. At this time, under the action of the spring 18, the second roller 21 at the side end of the first water pipe 19 is tightly attached to the ground. At this time, the first water pipe 19 is inserted between the two ridges of crops in an inclined state. Loosen the second locking bolt 32 and push and pull the rack 29 through the pull ring 34, and the third connecting pipe 25 can be rotated through the gear 27, so that it can be adjusted. The first nozzle 28 sprays in a direction such that during the spraying operation, the first nozzle 28 is adjusted to be vertically upward, and then the second locking bolt 32 is tightened. At this time, the medicine pump 39 is started, and the medicine pump 39 discharges the medicine liquid in the medicine storage barrel 38 into the second water pipe 4. Half of the medicine liquid entering the first water pipe 19 enters the third water pipe 35 through one end thereof. The medicine liquid entering the third water pipe 35 passes through the fourth connecting pipe 37, the second telescopic hose 36, the first connecting pipe 20, the first water pipe 19, the second connecting pipe 22, the first telescopic hose 24, and the third connecting pipe 25 in sequence, and then is sprayed upward through the first nozzle 28. In this way, the multiple first nozzles 28 on the first water pipe 19 spray the medicine liquid upward during the movement between the two ridges of crops, and thus can effectively spray the leaves of the crops. The bottom surface of the film can also be used to spray the lower layer of lush crops, effectively solving the problem that the medicine cannot be sprayed to the bottom layer of crops, and the other half of the medicine liquid entering the first water pipe 19 enters the third telescopic hose 41 through the other end thereof, and the medicine liquid entering the third telescopic hose 41 passes through the fifth connecting pipe 42 and the fourth water pipe 43 in turn, and is sprayed downward through the second nozzle 44, so that the second nozzle 44 can spray medicine downward from above the crops, and then through the first nozzle 28 on the first water pipe 19 and the second nozzle 44 of the fourth water pipe 43, the crops can be sprayed in all directions from top and bottom, thereby ensuring that the crops are sprayed in all directions without dead ends, so that pests have no hiding place, thereby improving the pest control effect.
