Description
Technical Field
[0001] The utility model belongs to the technical field of fruit tree maintenance, in particular to an insect-proof and sterilizing spray device for fruit trees. Background Art
[0002] During the maintenance of citrus trees, pests and diseases are relatively serious, such as citrus gummosis, citrus bark cracking, citrus gummosis and citrus Huanglongbing. Citrus gummosis, citrus bark cracking and citrus Huanglongbing are all fungal diseases, which are spread by insects and infect from wounds on branches or trunks. Whitewashing the trunks can effectively prevent fungal infection. The whitewashing work is currently mainly done manually by brushing with a brush dipped in whitewashing agent, which is very inefficient. On the other hand, in terms of spraying pesticides for pests and diseases, since the fruit trees have a certain height and the amount of spraying in the orchard is very large, the traditional method of spraying pesticides with a sprayer on the back is difficult to spray to a high place, and carrying a heavy medicine barrel is a very heavy farm work for fruit farmers. At the same time, since the spraying process cannot be relatively far away from the spraying rod, the pesticide will harm the health of the fruit farmers.
[0003] At present, there is no device that can simultaneously spray and whiten fruit trees. Utility Model Content
[0004] The utility model aims to provide a fruit tree insecticide spraying device, wherein the rotation of the motor can simultaneously drive the lifting and lowering of the spray arm, the winding and unwinding of the hose and the intermittent small-angle swinging of the spray arm, and can adapt to the whitewashing of tree trunks and the all-round spraying of fruit trees.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model discloses a fruit tree insecticide spraying device, comprising a bottom plate and a fixed frame vertically mounted on the bottom plate, a motor is mounted on the bottom end of the fixed frame, a vertical threaded rod is coaxially connected to the output shaft of the motor, an internal threaded block which slides up and down along the fixed frame is spirally sleeved on the threaded rod, a plurality of short racks are staggered on two opposite inner walls of the fixed frame, a first hollow tube is rotatably mounted on the front side of the internal threaded block, a gear which intermittently meshes with the short rack is fixedly mounted on the first hollow tube, a spray arm is fixedly connected to the front end of the first hollow tube; the spray arm is connected to the first hollow tube, and the first hollow tube is connected to a liquid storage tank through a hose.
[0007] Furthermore, both ends of the spray arm are detachably mounted with spray heads.
[0008] Furthermore, a U-shaped support frame is installed on the bottom plate, and a first rotating disk and a second rotating disk are rotatably installed on the inner side of the inner wall of the U-shaped support frame respectively, and a plurality of winding rods are fixedly installed between the first rotating disk 32 and the second rotating disk 321, and a hose is wound on the winding rod, and the water outlet end of the hose is connected to the first hollow tube.
[0009] Furthermore, the first rotating disk is rotatably mounted on the U-shaped supporting frame via a rotating rod, the end of the rotating rod extending into the inner side of the fixed frame is fixedly mounted with a first bevel gear, and the lower part of the threaded rod is fixedly mounted with a second bevel gear meshing with the first bevel gear; the rotating rod is fixedly connected to the first rotating disk.
[0010] Furthermore, a second hollow tube is fixedly installed through the outer side of the U-shaped support frame; and the second rotating disk is rotatably installed on the second hollow tube.
[0011] Furthermore, the inner end of the second hollow tube is connected to a hose, and the outer end is connected to a liquid storage tank through a fixed tube.
[0012] Furthermore, a second limiting ring is provided at the inner end of the second hollow tube, and a connecting pipe is rotatably installed at the inner end of the second hollow tube through the second limiting ring. A second limiting groove corresponding to the second limiting ring is opened on the inner wall of the connecting pipe. The second limiting ring is slidably connected to the inner wall of the second limiting groove, and the water outlet end of the connecting pipe is fixedly connected to the water inlet end of the hose.
[0013] Furthermore, a liquid pump is fixedly mounted on the fixed pipe, and one end of the fixed pipe away from the liquid pump is fixedly connected to the second hollow pipe.
[0014] Furthermore, a plurality of running wheels are arranged on the bottom surface of the bottom plate.
[0015] The utility model has the following beneficial effects:
[0016] 1. The utility model drives the threaded rod to rotate through a motor to drive the internal thread block to move up and down, thereby adjusting the height of the spray arm. At the same time, during the lifting and lowering of the spray arm, the gear that can rotate freely is alternately engaged with the short racks on its left and right sides to achieve intermittent clockwise and counterclockwise swinging. The spray can be sprayed by raising the motor to a certain height and fixing the angle of the spray arm, or by swinging the spray arm while raising and lowering, so as to spray the fruit trees in all directions. At the same time, by replacing different spray heads, the switch between whitewashing spraying on tree trunks and spraying on multiple fruit trees as a whole can be achieved, and one of the spray heads can be closed at will as needed.
[0017] 2. Through the meshing transmission of the first bevel gear and the second bevel gear, during the rising process of the spray arm, the rotating rod can be driven to rotate synchronously for unwinding, which can ensure that the rising height of the internal thread block and the unwinding action of the hose are carried out synchronously; similarly, the lowering height of the internal thread block and the rewinding action of the hose are also carried out synchronously, realizing the synchronization of the height adjustment of the internal thread block and the unwinding and rewinding action of the hose.
[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The specific working process of the utility model is:
[0039] When it is necessary to whitewash the tree trunks, one spray head 25 is usually closed and the other spray head 25 is opened. The spray head 25 is a special whitewash spray head with a larger spray hole. The opened spray head 25 is facing the trunk of the fruit tree, and the motor 26 is started to reverse and the spray arm 24 is lowered to the lowest position. At the same time, the liquid pump 5 and the motor 26 are turned on to rotate forward, so that the spray arm 24 swings up and down while rising, until the required height for whitewashing is reached. After whitewashing one side of the trunk, push the spray device to the other direction of the fruit tree, and completely cover the trunk of the fruit tree with whitewash in turn. After one whitewashing work is completed, add clean water through the water inlet at the upper rear end of the liquid storage tank 4, start the liquid pump 5, and clean the whitewashing liquid in the liquid storage tank 4, the hose 34 and the spray arm to avoid compaction and blockage of the liquid outlet.
[0040] When the whole orchard needs to be sprayed, the automatic button can be selected. After setting the height range of the spray arm 24, the motor 26 automatically switches forward and reverse according to the setting, and swings the spray arm while lifting and lowering it. The liquid pump 5 button can be started to spray. When the height and angle of the spray arm 24 need to be manually adjusted, the motor forward or motor reverse button is pressed to automatically switch to manual mode. After adjusting to the appropriate height, the "motor stop" button can be pressed to fix the angle and height for insecticide spraying.
[0041] The spray arm 24 of the utility model can be freely adjusted in height and angle, and can be used for whitewashing and spraying medicine in the whole range of the orchard.
