Description

Technical Field

[0001] The utility model relates to the technical field of farmland spraying pesticides, in particular to a backpack farmland spraying pesticide component. Background Art

[0002] The backpack spraying device is the main tool for spraying pesticides on farmland crops, also known as a sprayer, which can effectively prevent and control the invasion of crop diseases and pests. It belongs to the plant protection machinery among agricultural machinery. The traditional sprayer is usually composed of a spraying box, a spray rod, a high-pressure nozzle, a pressure rod and other components. The liquid medicine in the spraying box passes through the spray rod through the air suction principle of the pressure rod and is finally sprayed out at the high-pressure nozzle. However, the above-mentioned traditional sprayer has high labor intensity when in use, and requires frequent pressing and lifting of the pressure rod. In addition, the design of the single nozzle has a small spraying range, which makes the spraying efficiency low. Therefore, most of the electric sprayers on the market currently use a water pump installed in the spraying box to spray liquid pesticides using the water pump. For example, the Chinese patent announcement number is CN212697332U, Disclosed is a backpack pesticide spraying device for greenhouses. The device can realize electric spraying of pesticides over a large range through a submersible water pump 11 and multiple nozzles 9 connected to a horizontal tube 8. However, there are still major disadvantages in actual use. The angle of the horizontal tube 8 is relatively fixed and can only be used horizontally, so that the spraying direction of the nozzle is relatively fixed and cannot be flexibly adjusted according to the actual terrain and crop layout. The range that the drug can cover is only the crops in the vertical direction of the nozzle, and the coverage range is relatively low. For crops in corners, workers need to walk to the corners accurately for spraying. In areas with small space in corners such as greenhouses, spraying is difficult. In addition, during non-spraying, the horizontal tube occupies a large space, which is not conducive to storage and transportation. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a backpack-type farmland spraying component.

[0004] The technical solution of this utility model is as follows:

[0005] A backpack agricultural pesticide spraying assembly comprises a pesticide spraying box, wherein a water pump is arranged at the bottom of the pesticide spraying box to transport liquid pesticide in the pesticide spraying box to the outside of the pesticide spraying box;

[0006] The water pump is connected to a spraying pipe, and the spraying pipe is arranged outside the spraying box, and the spraying pipe is connected to a plurality of atomizing nozzles;

[0007] The side of the medicine spraying box is movably connected to a support rod through a connecting component, and the support rod can rotate in a horizontal plane. A plurality of atomizing nozzles are arranged along the length direction of the support rod and are connected to the support rod through buckles.

[0008] In order to expand the spraying area during spraying, two groups of spraying pipes are provided, and the two groups of spraying pipes are connected to the water pump through a three-way pipe.

The support rod can rotate around the articulated seat in a vertical plane.

[0012] In order to facilitate the rotation of the support rod to a vertical state for fixing, facilitate storage, and save space, an annular holder is installed on the side of the medicine spraying box above the mounting frame, which can clamp the support rod and fix it.

[0013] In order to ensure the stability of the support rod when it is stored, the distance between the annular holder and the mounting frame is 3 / 5-5 / 6 of the length of the support rod.

[0014] In order to ensure that the support rod can drive the spraying pipe to have a larger range of movement, the distance between the three-way pipe and the nearest atomizing nozzle is smaller than the length of the spraying pipe between the three-way pipe and the nearest atomizing nozzle.

[0015] In order to enable the atomizing nozzle to accurately spray the pesticide onto the crops, the atomizing nozzle is installed on the side of the support rod, and the atomizing nozzle is tilted downward.

[0016] In order to facilitate carrying the medicine spraying box and completing the medicine spraying work, two shoulder straps are arranged on the side of the medicine spraying box away from the three-way pipe.

[0018] Secondly, multiple atomizing nozzles are connected through the spraying pipe, and multiple atomizing nozzles are arranged along the length direction of the support rod, which expands the area covered by the spraying and can save the time of spraying;

[0019] Finally, the support rod can rotate in the horizontal plane, thereby driving the spraying tube and the atomizing nozzle to rotate in the horizontal plane, further expanding the spraying area of ​​the atomizing nozzle, allowing the user to hold the support rod to drive the spraying tube to rotate, facilitating the spraying of crops in corner areas, and the support rod can rotate in the vertical plane, thereby driving the spraying tube to rotate in the vertical plane, so that the spraying range can adapt to the spraying of crops with different heights, and the spraying angle can be adjusted according to the terrain or crop layout, and the support rod can be rotated to a vertical state for storage in the non-spraying state, saving storage space.

[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0031] Example

[0032] As mentioned in the background technology, the traditional sprayer requires the staff to constantly adjust the pressure rod when in use, and the design of a single nozzle has a small spraying range, high labor intensity and long spraying time. In the comparative patent improved based on the tradition, an electric and multi-nozzle sprayer is designed, which improves the spraying range and spraying efficiency to a certain extent, but the adjustment method is still relatively limited and cannot be flexibly adjusted according to the terrain, crop layout, etc. Therefore, the inventor has improved it on this basis and designed a new backpack spraying assembly, which is explained in detail below with reference to the drawings.

[0033] This embodiment provides a backpack agricultural spraying assembly. Figure 1 , including a spraying box 1, and in order to replace the traditional pressure rod for automatic spraying, a water pump 2 is arranged at the bottom of the spraying box 1, and a battery can be installed on the outside of the spraying box 1 to provide power for the water pump 2, and a control button is connected to control the opening and closing of the water pump 2. The water pump 2 can transport the liquid pesticide in the spraying box 1 to the outside of the spraying box 1. In this embodiment, the water pump 2 transports the liquid pesticide to the spraying pipe 3 outside the spraying box 1, and then sprays the pesticide on the crops through the atomizing nozzle 4 connected to the spraying pipe 3.

[0034] In the present embodiment, specifically, the spraying pipe 3 is arranged outside the spraying box 1, and the spraying pipe 3 is connected to a plurality of atomizing nozzles 4, so as to increase the spraying range of the spraying. In the present scheme, in order to enable spraying of pesticides on both sides when carrying the spraying box 1 for spraying, thereby improving the efficiency of spraying, two groups of the spraying pipes 3 are arranged, and the two groups of the spraying pipes 3 are connected to the water pump 2 through the tee pipe 8, the liquid inlet pipe of the tee pipe 8 is connected to the water pump 2, and the liquid outlet pipe is connected to the two spraying pipes 3, and the liquid outlet pipes are horizontally oriented to the two sides of the spraying box 1.

[0035] It should be noted that in order to be able to carry the medicine box 1, Figure 6 Two shoulder straps 10 are arranged on the side of the medicine spraying box 1 away from the three-way pipe 8. The shoulder straps 10 and the three-way pipe 8 are arranged on the opposite side of the medicine spraying box 1, and a cushion is arranged between the two shoulder straps 10 to improve the comfort when carrying.

[0036] In this embodiment, the two spraying tubes 3 extend toward the two sides of the spraying box 1 respectively, and in order to fix the spraying tubes 3, the side of the spraying box 1 is movably connected with a support rod 6. Corresponding to the number of spraying tubes 3, two support rods 6 are provided, which are respectively installed on the two sides of the spraying box 1, and the multiple atomizing nozzles 4 connected to the spraying tubes 3 are arranged along the length direction of the support rod 6. The atomizing nozzle 4 is installed on the side of the support rod 6 by a buckle 7. Figure 4The support rod 6 is set to be cylindrical, and the buckle 7 is arc-shaped and elastic, and can be clamped with the support rod 6. The installed side is the side away from the shoulder strap 10, so that the spray is sprayed in the opposite direction of the staff walking during spraying, reducing the amount sprayed on the user, and the atomizing nozzle 4 is tilted downward, so that it can be sprayed accurately on the crops during spraying.

[0037] One of the main technical points of this solution is that the support rod 6 is connected to the spray box 1 through the connecting assembly 5, and through the connecting assembly 5, the support rod 6 can rotate in the horizontal plane and the vertical plane, thereby driving the spray pipe 3 and the atomizing nozzle 4 to rotate in the above plane, thereby expanding the spraying range of the sprayer and being able to adapt to cultivated land with different terrains and different crop layouts. In addition, the spraying assembly is provided with two groups corresponding to the two support rods 6, which are respectively installed on both sides of the spray box 1, and in order to facilitate the staff to operate the support rod 6, the connecting assembly 5 is installed near the bottom of the spray box 1, so that when carrying the spray box 1, both hands can be bent to conveniently hold the support rod 6 near the spray box 1.

[0038] Specifically, the spraying assembly includes a mounting frame 51 mounted on the side of the spraying box 1, Figure 2 The mounting frame 51 can be plate-shaped, and the spraying rod is rotatably connected to the mounting frame 51 through a rotating shaft 52. Limiting plates are arranged at the upper and lower ends of the rotating shaft 52 to limit the rotating shaft 52 to prevent it from moving up and down. When it is necessary to rotate the spraying tube 3, the support rod 6 is held by hand and rotated around the rotating shaft 52 to realize the rotation of the spraying tube 3 in the horizontal plane.

[0039] Secondly, a hinge seat 53 is installed at the upper end of the rotating shaft 52, and the support rod 6 is rotatably connected to the hinge seat 53. The support rod 6 can rotate around the hinge seat 53 in a vertical plane. The hinge seat 53 is connected to the upper end of the rotating shaft 52. Through the setting of the hinge seat 53, the support rod 6 is pulled upward or pushed downward by hand, so that the support rod 6 can rotate toward or away from the medicine spraying box 1, thereby realizing the rotation of the support rod 6 in the vertical plane.

[0040] Moreover, it should be explained that the spraying pipe 3 can rotate along with the support rod 6, and the length of the spraying pipe 3 between the three-way pipe 8 and the atomizing nozzle 4 closest to the spraying box 1 should be sufficient to ensure the rotation of the spraying pipe 3, and ensure that the distance between the three-way pipe 8 and the nearest atomizing nozzle 4 is less than the length of the spraying pipe 3 between the three-way pipe 8 and the nearest atomizing nozzle 4, so that the spraying pipe 3 at this position is in a relaxed state, and can maintain the relaxed state during rotation to avoid affecting the stability of the connection between the spraying pipe 3 and the three-way pipe 8.

[0041] Moreover, in this scheme, combined with Figure 3 The spraying tube 3 can be stored along with the support rod 6. A ring-shaped holder 9 is installed on the side of the spraying box 1 above the mounting frame 51. The structure is as follows Figure 5 As shown, the support rod 6 can be clamped and fixed, and the annular clamping seat 9 has a certain elasticity. The support rod 6 is rotated upward to be in a vertical state, and is clamped in the annular clamping seat 9 to be fixed. In order to make the fixation more stable, the fixing point should be away from the mounting frame 51. The distance between the annular clamping seat 9 and the mounting frame 51 is 3 / 5-5 / 6 of the length of the support rod 6, which can effectively reduce the shaking of the upper end of the support rod 6 when it is in a vertical state. In the non-spraying state, the support rod 6 is vertically fixed on both sides of the spraying box 1, which greatly saves the space occupied by the support rod 6 in the horizontal direction and facilitates the storage and transportation of the spraying assembly.
