Description

Technical Field

[0001] The utility model relates to the field of agricultural irrigation devices, in particular to a sprinkler irrigation device with self-adaptive crop height. Background Art

[0002] During the growth process of crops, it is necessary to regularly spray liquid medicines such as insect repellents and herbicides on the crops. During the process of spraying the liquid medicine, it is necessary to avoid spraying the liquid medicine on the leaves of the crops, so as to prevent the leaves from absorbing the liquid medicine together during the process of water absorption, which has a certain impact on the growth of the crops. Conventional spraying methods such as spraying by unmanned aerial vehicles and manual spraying spray the liquid medicine from top to bottom, so that most of the liquid medicine falls on the leaves, which cannot meet the above spraying requirements. Therefore, a high medicine truck is commonly used to connect a sprinkler irrigation device for spraying. In the northern plain areas, the sunlight exposure in each area is basically the same, resulting in the same growth height of each row of crops in the area. The existing sprinkler irrigation devices can meet the spraying requirements. However, in the hilly areas of the south, the sunlight exposure in each area is affected by the slope change and will change, which has a greater impact on the growth of crops. Often, the height of each row of crops in the same area is different, and it is commonly in a convex shape, that is, the crops near the road on both sides are lower in height than the crops in the middle. The spraying heights of all the nozzles in the existing sprinkler irrigation devices are the same, and they cannot adapt to the work of spraying liquid medicine on crops in this kind of landform. Summary of the Utility Model

[0021] Among them: connecting frame 1; positioning block 11; threaded hole 12; fixing frame 2; shunt row 21; connecting hose 22; lifting part 3; lead screw 31; motor 32; connecting part 33; nozzle 34; medicine barrel 4; tee joint 41. Specific embodiments

[0022] This application includes a connecting frame 1 for connecting a spraying assembly, which is the same as the prior art. The connecting frame 1 is installed on a high medicine vehicle, and the height of the connecting frame 1 from the ground is controlled by the high medicine vehicle. A plurality of spraying assemblies for spraying medicine liquid, as shown in Figure 1 are symmetrically arranged at both ends of the connecting frame 1. Among them, the spraying assembly is used to spray the medicine liquid on the stems of plants rather than on the leaves, so as to avoid the plants absorbing the medicine liquid together when absorbing water on the surface of the leaves, thereby affecting the growth of the plants. The spraying assembly can achieve the above functions by adjusting the spraying height. In the northern plain area, the lighting of plants in the same area is almost the same, so that the heights of plants in this area are similar. By adjusting the height of the connecting frame 1 through the high medicine vehicle, the spraying of the medicine liquid on the stems of plants can be realized. However, in the southern hilly area, the lighting of plants in the same area varies greatly, resulting in different plant heights in this area. Specifically, the heights of plants in different rows will be different. The multiple spraying assemblies symmetrically arranged at both ends of the connecting frame 1 can independently adjust the spraying height according to the plant height to ensure that the medicine liquid can be sprayed onto the stems of each row of plants.

[0023] As shown in Figure 1 the spraying assembly includes a lifting part 3 arranged on the connecting frame 1. A nozzle 34 for spraying medicine liquid is arranged at the bottom end of the lifting part 3. A lead screw 31 is rotatably connected inside the lifting part 3. The connecting frame 1 is connected to the lead screw 31 through a positioning block 11. A threaded hole 12 is penetrated through the positioning block 11. The lead screw 31 is connected to the threaded hole 12 by a thread. Driving the rotation of the lead screw 31 makes the connected lifting part 3 move along the axial direction of the lead screw 31, thereby driving the nozzle 34 arranged at the bottom end of the lifting part 3 to move in the same direction, so as to change the spraying height of the nozzle 34. Further, in order to facilitate the control of the height of the nozzle 34, a motor 32 capable of self-locking is arranged at the top end of the lifting part 3. The output shaft of the motor 32 is connected to the lead screw 31, and the motor 32 provides power for the rotation of the lead screw 31. An independent control module is arranged on each motor 32. The output end of the control module is connected to the motor 32, and the input end of the control module is arranged on the high medicine vehicle for the convenience of the staff to adjust and control according to the height of the plants.

[0024] Among them, as shown in Figure 3The shown connecting frame 1 is provided with a flow dividing row 21 for dividing the liquid medicine to each spraying component. There are two flow dividing rows 21 which are symmetrically arranged at both ends of the connecting frame 1. The flow dividing row 21 is fixedly connected to the connecting frame 1 through a fixedly arranged fixing frame 2 with a hollow interior. The spray head 34 is connected through a connecting part 33 as shown in Figure 4 . The connecting part 33 is connected to the flow dividing row 21 through a connecting hose 22. The connecting part 33 transports the liquid medicine into the spray head 34 for spraying. The connecting hose 22 is usually made of deformable pipe materials such as corrugated pipes and rubber hoses, which can ensure the firm connection between the flow dividing row 21 and the connecting part 33 when the distance between the spray head 34 and the flow dividing row 21 changes.

[0025] A medicine bucket 4 as shown in Figure 1 is arranged on the connecting frame 1. A tee joint 41 as shown in Figure 5 is connected to the medicine bucket 4. The tee joint 41 is fixed and communicated with the flow dividing row 21. The liquid medicine in the medicine bucket 4 is divided into two flow dividing rows 21 through the tee joint 41, and the liquid medicine is transported to each connecting hose 22 through the flow dividing row 21, so that the spray head 34 can spray the liquid medicine to the designated position. In order to facilitate the staff to control the spraying time, an electric control switch is arranged on the tee joint 41, and the control end of the switch is installed on the high medicine vehicle for the driver to operate.
