Description

Technical Field

[0001] The utility model relates to the technical field of greening insect killing, and more specifically, it relates to a greening insect killing structure for gardens and landscapes. Background Art

[0002] Landscape gardening refers to the activity of using the ornamental characteristics and ecological functions of plants to beautify the environment and restore the ecology in urban and rural planning. Garden plants are prone to being invaded by various pests and diseases during their growth process. In order to protect the healthy growth of plants, a greening insect killing structure for gardens and landscapes is needed to spray insecticidal pesticides. During the use of the existing greening insect killing structure, powdered pesticides are usually directly put into the mixing tank and then mixed and stirred. This mixing method causes the pesticide powder to enter the mixed liquid concentratedly, which may cause the pesticides to form lumps, thereby reducing the mixing uniformity, resulting in uneven distribution of pesticides and affecting the insecticidal effect. Secondly, during the use of the existing greening insect killing structure, pesticides are usually sprayed onto plants through multiple nozzles, but usually only one side of the plants can be sprayed with pesticides. Therefore, the entire device needs to be moved and then the other side is sprayed, which is rather cumbersome in operation and reduces the practicability of the entire device.

[0032] In this embodiment, when it is necessary to configure pesticides, a liquid inlet hopper is provided at the upper end of the mixing tank 1. Liquids are placed into the mixing tank 1 from the liquid inlet hopper, causing multiple stirring rods 13 to rotate. The stirring rods 13 stir the liquids in the mixing tank 1. Meanwhile, pesticide powders are placed into the feed hopper 2. The first motor 4 is started, and the first motor 4 drives the rotating rod 3 to rotate. The rotating rod 3 drives multiple blanking plates 5 to rotate, thereby uniformly discharging the pesticide powders. The discharged pesticide powders fall onto the sieve plate 10. The second motor 11 is started, and the second motor 11 drives the convex column 12 to rotate. When the protruding part of the convex column 12 rotates into contact with the moving frame 9, the moving frame 9 is pushed to move as the convex column 12 rotates.

When the spray pipe 15 sprays pesticides, start the fourth motor 20. The fourth motor 20 drives the screw rod 19 to rotate. Since the screw rod 19 is threadedly connected to the lifting seat 21, the lifting seat 21 moves up and down. The lifting seat 21 drives the telescopic assembly and the spray pipe 15 to move, so as to spray pesticides on different parts of the entire plant.

[0038] Please refer to Figures 1-5 As an implementation manner for adjusting the position of the spray pipe 15: The telescopic assembly includes a telescopic shell 26 fixedly arranged on one side of the adjusting seat 25.

[0042] To sum up, when the whole device is in use:

[0043] When in the state of needing to prepare the insecticidal pesticide solution, a liquid inlet hopper is arranged at the upper end of the mixing tank 1. Place the liquid into the mixing tank 1 from the liquid inlet hopper. Start the third motor 16. The third motor 16 drives the stirring shaft 17 to rotate. The stirring shaft 17 drives multiple stirring rods 13 to rotate. The stirring rods 13 stir the liquid in the mixing tank 1. At the same time, place the pesticide powder into the feeding hopper 2. Start the first motor 4. The first motor 4 drives the rotating rod 3 to rotate. The rotating rod 3 drives multiple blanking plates 5 to rotate, so as to uniformly feed the pesticide powder. The fed pesticide powder falls onto the sieve plate 10. Start the second motor 11. The second motor 11 drives the convex column 12 to rotate. When the protruding part of the convex column 12 rotates to contact the moving frame 9, with the rotation of the convex column 12, it will push the moving frame 9 to move. The moving frame 9 drives the sieve plate 10 to move, and the spring 8 is compressed. When the protruding part of the convex column 12 rotates to separate from the moving frame 9, under the push of the spring 8, the moving frame 9 drives the sieve plate 10 to move back to its original position. Repeat the operation like this, and the sieve plate 10 will shake back and forth, so that the pesticide powder falling onto the sieve plate 10 is sieved and dispersed at the same time, and falls into the stirring liquid, preventing the pesticide powder from caking. Under the stirring of the stirring rods 13, the pesticide powder and the solution are stirred and mixed, and the pesticide solution can be prepared.

[0044] When in the state of needing to adjust the positions of the two nozzles 15 according to the positions of the plants, multiple rollers are arranged at the lower end of the movable seat 14. Push the movable seat 14, and the whole device can be moved. The electric push rod 29 can be started according to the position of the plant.

[0045] When in a state where it is necessary to adjust the distance between the two spray pipes 15 according to the size of the plant, the fifth motor 24 is started. The fifth motor 24 drives the bidirectional lead screw 23 to rotate. There are two thread areas with opposite directions on the bidirectional lead screw 23, so that the two adjusting seats 25 move in the adjacent direction. The adjusting seats 25 drive the two spray pipes 15 to move through the telescopic assembly, thereby adjusting the distance between the two spray pipes 15 according to the size of the plant. When the spray pipes 15 are spraying pesticides, the pump body 31 is started. The pump body 31 transports the pesticide solution prepared in the mixing tank 1 to the spray pipes 15 through the hose 32. There are multiple nozzles on the spray pipes 15, so as to spray insecticidal pesticides on the plants. At the same time, the fourth motor 20 is started. The fourth motor 20 drives the screw rod 19 to rotate. Since the screw rod 19 is threadedly connected to the lifting seat 21, the lifting seat 21 moves up and down.
