Description

Technical Field

[0001] The utility model relates to the technical field of seedling irrigation, in particular to an automatic spraying device for irrigation and fertilization of seedlings in forest farms. Background Art

[0002] Seedlings are tree seedlings with root systems and trunks. All seedlings cultivated in nurseries, regardless of their age, are called seedlings before they are planted. There are several types of seedlings, including seedlings from seeds, vegetative propagation seedlings, transplanted seedlings and bed-keeping seedlings. Seedlings can also be classified according to trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. Garden seedling cultivation is a technical measure to breed and cultivate seedlings to meet the requirements of landscaping. Seedlings, as plants, have their natural growth laws. In view of the role of greening and oxygen production in purifying the air, local governments and the country strongly advocate green cities. Therefore, the demand for seedlings is very large, and they must be circulated through the market. The core lies in the nationally renowned flower and tree market. Greening seedlings are most commonly used in urban gardening and greening, such as urban greening, residential greening, highway greening, barren mountain greening and river bank greening. The planting of seedlings requires Apply water and fertilizer, but the existing water and fertilizer application device has a fixed spraying area when in use, so the efficiency is low and cannot meet the fertilization needs. To solve the above problems, a technical solution is disclosed in Patent No.: CN202022003700.X, but the technical solution still has some problems when in use. Although the spraying area can be changed when the technical solution is in use, the size and height of the seedlings are different, resulting in different sizes of the facades of the crowns. The equipment can only be poured on a horizontal plane when in use. When the size of the crowns is different, it is easy for the liquid to not be completely immersed in the bottom of the seedlings during pouring, and when the equipment needs to be irrigated at a long distance, the equipment cannot automatically change its flow rate, so that it cannot fully irrigate the distant area, thereby reducing the irrigation efficiency of the equipment.

[0003] Based on this, the utility model designs an automatic spraying device for irrigation and fertilization of seedlings in forest farms to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an automatic spraying device for irrigation and fertilization of forest seedlings, so as to solve the problem that the equipment proposed in the above background technology cannot change the irrigation angle, thus affecting the irrigation efficiency and quality of the equipment.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The spraying device is characterized in that the spraying pipe is provided with a hydraulic rod, a flow rate control mechanism is arranged on the spraying pipe, a spray head is installed on the flow rate control mechanism, a first adjusting plate and a second adjusting plate are rotatably connected in the spray head, a second gear ring is installed on the second adjusting plate, a transmission rod is rotatably connected on the spray head, the transmission rod is meshed with the flow rate control mechanism, a second gear is installed on the transmission rod, the second gear and the second gear ring are meshed, a third gear is installed at one end of the transmission rod, a rack is installed on the rotating disk, the rack and the third gear are meshed, a liquid storage tank is installed on one side of the fixed plate, a liquid supply assembly is arranged between the liquid storage tank and the spraying pipe, and a driving motor is installed on the lower side of the rotating disk.

[0007] Preferably, the flow rate control mechanism includes an outer shell, a first gear ring, a closing plate, a pull rod, a rotating column and a first gear. The spray pipe is installed with an outer shell, the first gear ring is rotatably connected in the outer shell, a plurality of closing plates are rotatably connected in the outer shell, a pull rod is provided between the closing plate and the first gear ring, the outer shell is rotatably connected with a rotating column, a first gear is installed on the rotating column, and the first gear is meshingly connected with the first gear ring.

[0008] Preferably, the first adjustment plate and the second adjustment plate are both provided with through holes, and filters are provided in the through holes.

[0009] Preferably, a mixing assembly is provided in the liquid storage tank, and the mixing assembly is transmission-connected to the rotating disk.

[0010] Preferably, a dustproof net is provided on the front side of the nozzle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model places the device at a suitable position and controls the driving motor to work. When the driving motor works, the rotating disk rotates and the mixing component works at the same time, so that the device can swing left and right to spray during the spraying process, and can ensure the mixing of the liquid during the spraying process to prevent the mixed dissolution from being uneven.

[0013] 2. When the equipment needs to adjust the spraying according to the height of the tree crown or the position of the root, the length of the hydraulic rod is adjusted. When the spray pipe is adjusted downward, the third gear rotates driven by the rack. At this time, the transmission rod drives the second gear and the rotating column to rotate at the same time. When the rotating column rotates, the first gear drives the first gear ring to rotate, and then the multiple closed plates move away from each other, thereby increasing the gap between them. At the same time, the second gear drives the second gear ring to rotate, so that the through-hole gap between the first adjustment plate and the second adjustment plate becomes larger, so that the pressure of the equipment becomes smaller and the flow rate becomes larger during spraying, thereby avoiding damage to the seedlings caused by excessive pressure during irrigation. On the contrary, when the spray pipe swings upward, the multiple closed plates approach each other and the gap between the through holes becomes smaller, thereby increasing the pressure in the equipment and reducing the liquid flow rate in the spray pipe, so that it can spray farther during irrigation, so that it can adapt to different irrigation positions, thereby further improving the irrigation efficiency and convenience of the equipment.

[0025] Among them, the flow rate control mechanism 5 includes an outer shell 6, a first gear ring 7, a closing plate 8, a pull rod 9, a rotating column 10 and a first gear 11. The outer shell 6 is installed on the spray pipe 3, and the first gear ring 7 is rotatably connected in the outer shell 6. Multiple closing plates 8 are rotatably connected in the outer shell 6. A pull rod 9 is provided between the closing plate 8 and the first gear ring 7. The rotating column 10 is rotatably connected in the outer shell 6. The first gear 11 is installed on the rotating column 10, and the first gear 11 is meshingly connected with the first gear ring 7; the flow rate of the equipment can be effectively controlled, thereby increasing the spraying pressure of the equipment, and then the equipment can be adjusted to a farther distance for spraying, thereby realizing long-distance irrigation.

[0026] The first adjustment plate 13 and the second adjustment plate 14 are both provided with through holes, and filters are provided in the through holes, so as to change the size of the through holes and thus change the spraying flow rate of the equipment.

[0027] A mixing assembly 22 is provided in the liquid storage tank 20, and the mixing assembly 22 is transmission-connected to the rotating disk 2, so that the liquid can be mixed conveniently and mixed during the spraying and adjusting process, thereby reducing the use of power source.

[0028] A dust screen is provided at the front side of the nozzle 12 to prevent foreign matter from entering the nozzle 12 and causing blockage.

[0029] Working principle:

[0030] When working, place the device in a suitable position and control the driving motor 23 to work. When the driving motor 23 is working, the rotating disk 2 rotates, and the mixing component 22 works at the same time, so that the device can swing left and right to spray during the spraying process, and can ensure the mixing of the liquid during the spraying process to prevent the mixed dissolution from being uneven.

When the spraying pipe 3 is adjusted downward, the third gear 18 rotates under the drive of the rack 19. At this time, the transmission rod 16 simultaneously drives the second gear 17 and the rotating column 10 to rotate. When the rotating column 10 rotates, the first gear 11 teeth The wheel drives the first gear ring 7 to rotate, thereby moving the multiple closed plates 8 away from each other, thereby increasing the gap between them. At the same time, the second gear 17 drives the second gear ring 15 to rotate, thereby increasing the through-hole gap between the first adjustment plate 13 and the second adjustment plate 14, so that the pressure of the equipment is reduced and the flow rate is increased during spraying, thereby avoiding damage to the seedlings due to excessive pressure during the irrigation process. On the contrary, when the spray pipe 3 swings upward, the multiple closed plates 8 approach each other and the gaps between the through holes are reduced, thereby increasing the pressure in the equipment and reducing the flow rate of the liquid in the spray pipe 3, thereby making it spray farther during irrigation, so that it can adapt to different irrigation positions, thereby further improving the irrigation efficiency and convenience of the equipment.
