Description

Technical Field

[0001] The utility model relates to the technical field of tree cultivation, in particular to a drug spreading tool used for forest tree breeding. Background Art

[0002] Breeding refers to the technology and process of selecting or creating excellent plant varieties. It can be used to cultivate seedlings and crops. Before planting, gardens need to breed flowers and trees. During the breeding process, they need to be sprayed with pesticides at the seed stage and the seedling stage to prevent viruses and pests to ensure the healthy growth of seeds or seedlings. In existing breeding work, pesticide spreading tools are usually used for spraying pesticides, but when in use, the spraying angle is fixed and requires frequent manual adjustment of the angle to expand the range of the spraying, or the spraying tool is carried manually and manually rotated to adjust the spraying angle. The above two methods are both troublesome when spreading pesticides and require frequent labor. On the one hand, it increases the labor cost investment. On the other hand, if the breeding area is large, the labor intensity of manual labor is high and the spraying speed is low. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, in the process of tree breeding, pesticides need to be sprayed regardless of the seed stage or the seedling stage to prevent and control pests and diseases. A spraying tool is needed for spraying pesticides. The prior art usually uses a fixed-angle spraying tool or a backpack-type spraying tool. The fixed angle of the nozzle 6 requires frequent adjustment of the spraying angle, while the backpack-type spraying tool requires long-term manual movement during use, and requires frequent hand swinging of the spraying direction. Both require a large amount of manpower and energy to complete the spraying work, and the labor intensity is high, which makes the spraying speed slow. Therefore, the inventor has improved the existing spraying tool and designed a new type of spraying tool to overcome the above problems. The following is a specific explanation with reference to the drawings.

[0030] This embodiment provides a spraying tool for tree breeding, see Figure 1, including a movable medicine storage barrel 1. In the present embodiment, the movement of the medicine storage barrel 1 is mainly achieved in two ways. A handle 12 is rotatably connected to the upper part of the medicine storage barrel 1 and is installed on the side of the medicine storage barrel 1. The staff can carry the medicine storage barrel 1 by the handle 12 and move it. Secondly, a universal wheel 13 is provided at the bottom of the medicine storage barrel 1, and the staff can push the medicine storage barrel 1 to move it, thereby facilitating the movement of the medicine storage barrel 1.

[0031] In this embodiment, combined with Figure 3 A liquid pump 2 is arranged at the bottom of the medicine storage barrel 1, and the liquid pump 2 is a submersible type. A medicine outlet 3 is arranged on the side of the medicine storage barrel 1. The inside of the medicine outlet 3 is connected with the liquid pump 2 through a liquid inlet pipe 4, and the outside is connected with a nozzle 6 through a liquid outlet pipe 5. Through the action of the liquid pump 2, the liquid medicine in the medicine storage barrel 1 can be transported to the nozzle 6 through the liquid inlet pipe 4 and the liquid outlet pipe 5, and the liquid medicine is sprayed out through the nozzle 6.

[0032] One of the main technical points of this solution is that the spray head 6 is connected to the medicine storage barrel 1 through a bracket 7. In this embodiment, the bracket 7 is made of flexible metal. In order to facilitate the adjustment of the tilt angle of the spray head 6 in the vertical direction, the bracket 7 includes a horizontal section 71 fixed to the rotating shaft 8, and a bending section 72 is provided on one side of the horizontal section 71, which is arranged away from the rotating shaft 8. An upwardly bent inclined section 73 is provided on one side of the bending section 72. The spray head 6 is installed at an angle with the end of the inclined section 73. The bending section 72 can adjust the bending angle according to the distance of spraying the medicine as needed, and then the tilt angle of the inclined section 73 can be adjusted. In order to prevent excessive adjustment, the tilt angle of the inclined section 73 is 10°-45°, which can avoid excessive adjustment of the bending section 72 while ensuring a suitable spraying distance.

[0033] On the basis of the above structure, the bracket 7 is installed on the rotating shaft 8. When the rotating shaft 8 rotates, it can drive the bracket 7 to swing. The rotation of the rotating shaft 8 is mainly achieved by driving the driving device 9 arranged in the medicine storage barrel 1. The rotating shaft 8 passes through the medicine storage barrel 1 and is connected with the driving device 9. The driving device 9 can drive the rotating shaft 8 to rotate clockwise or counterclockwise, and then drive the bracket 7 to swing left and right. In order to ensure a larger swinging angle and then expand the range of spraying medicine, the maximum angle of the rotating shaft 8 counterclockwise or clockwise rotation is 30°-80°, and the rotation angle of the rotating shaft 8 can be adjusted according to the size of the area to be sprayed.

[0034] In order to protect the part of the rotating shaft 8 exposed to the outside of the medicine storage barrel 1, a protective shell 11 is provided on the barrel cover of the medicine storage barrel 1, which can wrap the upper end of the rotating shaft 8 to prevent the rotating shaft 8 from being corroded by liquid.

[0035] In order to further separate the driving device 9 from the liquid in the medicine storage barrel 1 and prevent the liquid from damaging the driving device 9, an L-shaped partition 10 is installed at the upper end of the medicine storage barrel 1, and a driving cabin is formed between the L-shaped partition 10 and the side wall of the medicine storage barrel 1 and the barrel cover. The driving device 9 is installed in the driving cabin between the L-shaped partition 10 and the inner wall of the medicine storage barrel 1.

[0036] Specific, combined Figure 2 and Figure 4 The driving device 9 includes a driving motor 91 mounted on the L-shaped partition 10, the output end of the driving motor 91 is connected to an eccentric mechanism, and the output end of the driving motor 91 is perpendicular to the Figure 2 The view direction is shown, and the eccentric mechanism includes a turntable 95 connected to the output end of the drive motor 91, the turntable 95 is eccentrically connected to a connecting rod 96, and the connecting rod 96 is rotatably connected to the connecting position of the turntable 95, and the connecting rod 96 can make eccentric movements with the turntable 95, and the end of the connecting rod 96 away from the turntable 95 is connected to a rack 92, the rack 92 is slidably arranged with the vertical plate of the L-shaped partition 10, and the teeth of the rack 92 face the drive motor 91, when the connecting rod 96 moves eccentrically, it can drive the rack 92 to reciprocate, and in order to realize the rotation, a gear 93 is installed at the bottom end of the rotating shaft 8, the bottom of the gear 93 is supported and rotated by a supporting shaft, the rack 92 is meshed with the gear 93, and when the rack 92 reciprocates, it can respectively mesh with the gear 93, driving the gear 93 to reciprocate clockwise or counterclockwise, and then driving the rotating shaft 8 to reciprocate.

[0037] In order to limit the rack 92 and improve the stability of the rack 92 when it moves, thereby ensuring stable engagement with the gear 93, two limiting plates 94 are provided in the vertical section of the L-shaped partition 10, and the rack 92 is slidably arranged between the limiting plates 94, and the limiting plates 94 can limit the upper and lower ends of the rack 92.
