Abstract
Description
Technical Field
[0001] This utility model relates to the field of Glycyrrhiza uralensis planting technology, and more specifically, to a crop spraying device for Glycyrrhiza uralensis planting. Background Technology
[0002] Existing pipeline spraying devices typically use fixed nozzles to spray pesticides around fruit trees. However, due to the significant height differences among fruit trees at different growth stages, fixed nozzles can only cover fruit trees within a specific height range, resulting in ineffective coverage of a wider area. This limitation means that some fruit trees cannot be covered by the spray, thus affecting the uniform distribution and control effect of the pesticide. Furthermore, commonly used pipeline spraying devices can only spray in a fixed direction and cannot adjust the spraying angle or range according to actual needs, which further limits the coverage efficiency of the pesticide. Utility Model Content
[0003] The purpose of this invention is to overcome the limitation that fixed nozzles can only cover fruit trees within a specific height range due to the large height differences at different growth stages of fruit trees, resulting in the inability to effectively cover a wider range of fruit trees. This limitation means that some fruit trees cannot be covered by the spray, thus affecting the uniform distribution of the pesticide and the control effect. The invention provides a spraying device that can spray a large amount of gas while spraying the mist-like pesticide, forming an air curtain on both sides of the mist-like pesticide, thereby reducing pesticide waste.
[0004] Another objective of this invention is to provide a crop spraying device for planting oleander with the above-mentioned functions.
[0005] The embodiments of this utility model are achieved through the following technical solution: a crop spraying device for planting oleander, including support rods and connectors; each support rod is fixedly connected to a connector, and the two connectors are symmetrically distributed from left to right; it also includes a round tube, an atomizing nozzle, a hollow plate, and a manual valve; the connector is composed of a shell, a rotating body, and a connecting tube, the rotating body is rotatably connected inside the shell, one end of the rotating body is fixedly connected to two connecting tubes, the rotating body has two symmetrically distributed cavities inside, each cavity communicates with a connecting tube, and the other end of the rotating body has a docking groove; the shells and rotating bodies of the two connectors are connected to a round tube. Furthermore, the inner part of the circular tube is provided with two semi-circular channels that are symmetrically distributed vertically; the interfaces at both ends of the circular tube are inserted into the mating grooves of the connectors; several atomizing nozzles are installed at equal intervals at the lower part of the circular tube, and all atomizing nozzles are connected to the semi-circular channels at the lower part of the circular tube; the outer ring surface of the circular tube is connected to two hollow plates that are symmetrically distributed front and back, and both hollow plates are connected to the semi-circular channels at the upper part of the circular tube; each hollow plate is provided with a guide part, and the guide parts of the two hollow plates are located on both sides of all atomizing nozzles, forming an outward octagonal shape; a manual valve is installed on the opposite side of each of the two connectors, and the manual valves are connected to the two connecting pipes of the rotating body.
[0006] Further explanation includes an annular groove on the housing; a spring fixedly connected within the annular groove; a connecting ring fixedly connected to the spring; several pins arranged in a circular array fixedly connected to the side of the connecting ring, and all pins penetrating the housing; several sliding grooves arranged in a circular array of four on the housing; several connecting posts arranged in a circular array fixedly connected to the outer surface of the connecting ring, and all connecting posts slidingly disposed within the sliding grooves; a push ring fixedly connected to all connecting posts; and several pin holes arranged in a circular array at each end of the round tube, with the pin holes matching the pins.
[0007] To further explain, it also includes several hooks that are equidistantly distributed and fixed to the upper part of the circular tube and the outer surface of the support rod; several hooks on the outer surface of the support rod face the circular tube.
[0008] To elaborate further, each support rod has a conical column connected to its lower part.
[0009] To further explain, the cone column and the support rod are detachably connected, which is used to install different bases and facilitates fixing the device in different environments.
[0010] To further clarify, all components of this device are made of corrosion-resistant metal materials.
[0011] The beneficial effects of this utility model are as follows:
[0012] The crop spraying device for planting Glycyrrhiza uralensis obtained by the above design can rotate the orientation of the atomizing nozzle on the round tube to any desired angle through the cooperation of the pin and the pin hole, so as to achieve the effect of spraying liquid. It can adapt to the height of fruit trees at different growth stages and increase the practicality of the device.
[0013] This utility model, through the above-described design, provides a crop spraying device for planting Glycyrrhiza uralensis. The air curtain formed by the continuous exhaust from two hollow plates restricts the sprayed liquid from the atomizing nozzles, preventing it from extending through the air curtain into the passageway and thus avoiding its random dispersion in the air. Furthermore, when the atomizing nozzles are rotated to operate at an upward tilt, the airflow exiting from the guide sections of the two hollow plates not only restricts and intercepts the liquid spray but also blows it higher, above the fruit trees, where it falls onto the trees under gravity, further increasing the spraying height.
[0014] This utility model provides a crop spraying device for planting Gynostemma pentaphyllum, which is an assembled structure that can be added according to the actual needs of fruit tree planting, extending the working range of the device. At the same time, the spraying range of the device can be adjusted according to the size of the fruit trees, improving the practicality of the device. Furthermore, when cultivating fruit tree seedlings, windproof cloths can be hung on the support rods and round pipes of the four spraying devices. The windproof cloths are held taut by the hooks on the support rods and round pipes, thus protecting the Gynostemma pentaphyllum seedlings inside the windproof cloths and preventing them from being blown over by strong winds and dying.

[0029] It also includes a circular tube 3, an atomizing nozzle 4, a hollow plate 5, and a manual valve 6; the connector 2 consists of a housing 21, a rotating body 22, and a connecting pipe 23.

[0033] The cone column 107 is detachably connected to the support rod 1 for mounting different bases, making it easy to fix the device in different environments.
[0034] All components of this device are made of corrosion-resistant metal materials.
[0035] The working steps of this embodiment are as follows:
[0036] The following orientations are based on the viewpoint shown in the diagram, with the direction of manual valve number 6 being to the right;
[0037] For ease of understanding of the following text, the crop spraying device for planting Glycyrrhiza uralensis will be referred to as: spraying device;
[0038] When spraying pesticides on the planned plantings of Indian gooseberry trees in the garden, taking one row of trees as an example, the operator installs a sprayer on each side of the row of trees, positioning the trees between the two sprayers, and leaving a certain distance between the trees and the sprayers. Figure 5As shown, at this point, the device is an assembled structure. Two spraying devices alone cannot completely cover this row of fruit trees. Therefore, the operator can continue to add spraying devices to the spraying devices on both sides, allowing the spraying devices to extend along the distribution direction of the fruit trees. This allows for the addition of this device according to actual needs, extending the working range of this device until the entire row of fruit trees is within the coverage range of the spraying devices on both sides. At this time, the two adjacent spraying devices are connected by two hoses. The two ends of the upper hose are sleeved on the upper connecting pipes 23 of the two adjacent rotating bodies 22, and the two ends of the lower hose are sleeved on the lower connecting pipes 23 of the two adjacent rotating bodies 22, so that the two semi-circular channels 3001 of the circular pipes 3 on all spraying devices are connected. In addition, two manual valves 6 are installed at the beginning and end of the spraying devices on both sides, respectively. The manual valve 6 at the beginning is connected to two pipes. One pipe is connected to an air compressor pump and is connected to the upper semi-circular channel 3001 of the circular pipe 3 of the spraying device. The other pipe is connected to a liquid delivery device and is connected to the lower semi-circular channel 3001 of the circular pipe 3 of the spraying device.
[0039] Before using the spraying device, the operator needs to adjust the circular tubes 3 on all the spraying devices according to the height of the existing fruit trees. Several atomizing nozzles 4 at the bottom of the circular tubes 3 need to be rotated to face the fruit trees. Taking one spraying device as an example, the operator needs to simultaneously grasp the push rings 105 on the two connectors 2. The push rings 105 push the connecting rings 102, pins 103, and connecting posts 104 together within the annular groove 2101, moving them away from the circular tubes 3. This forces the spring 101 to compress, causing several pins 103 to move out of the pin holes 3002 of the circular tubes 3. Then, the operator grasps the circular tubes 3 and rotates them on the two connectors 2. The circular tubes 3 will drive the atomizing nozzles 4, the hollow plate 5, and the rotating parts within the two connectors 2. 22 and connecting pipe 23 rotate together, turning the orientation of the atomizing nozzle 4 on the round pipe 3 to any desired angle to spray the medicine. This allows the device to adapt to the height of fruit trees at different growth stages, increasing its practicality. After several atomizing nozzles 4 on the round pipe 3 are rotated to face the fruit tree, the operator releases the two push rings 105. Under the action of the elastic force, the spring 101 drives the connecting ring 102, the pin 103, the connecting column 104 and the push ring 105 to reset together. At this time, if the pin 103 is not inserted into the pin hole 3002 of the round pipe 3, the operator can continue to hold the round pipe 3 and rotate it to let several pins 103 be inserted into the corresponding pin holes 3002, preventing the round pipe 3 from rotating downwards under the action of gravity.
[0040] After all the circular pipes 3 of the spraying devices are adjusted, the operator opens the manual valve 6 at the head end to control the air compressor pump and the liquid delivery equipment to start. The air compressor pump delivers gas through the pipe to the upper semi-circular channel 3001 of all the circular pipes 3, and then discharges it from the guide part 5001 of the two hollow plates 5. At this time, the guide part 5001 of the two hollow plates 5 is shaped like an outward octagon. Therefore, the airflow continuously discharges from the guide part 5001, forming an outward octagonal air curtain on both sides of several atomizing nozzles 4. At the same time, the liquid delivery equipment also delivers the prepared liquid to the lower semi-circular channel 3001 of all the circular pipes 3 through the pipe, and then sprays it out from all the atomizing nozzles 4, spraying the liquid in a mist onto the fruit trees. The air curtain formed by the continuous exhaust of the two hollow plates 5 can restrict the mist liquid sprayed from the atomizing nozzles 4, preventing the mist liquid from passing through the air curtain and extending into the passage, thus avoiding the mist liquid from drifting randomly in the air.
[0041] It should be noted that when the atomizing nozzle 4 of the round tube 3 on the spraying device is rotated to tilt upwards for spraying, the airflow discharged from the guide section 5001 of the two hollow plates 5 can not only restrict and intercept the atomized liquid, but also blow the atomized liquid higher, blowing it above the fruit tree, and then, under the action of gravity, it falls onto the fruit tree, further increasing the spraying height.
[0042] When it is necessary to spray a mist of pesticide onto young oleifera seedlings in the orchard, four sprayers can be installed in a rectangular shape, such as... Figure 6 As shown, the seedlings of the amla tree are planted within four rectangular spraying devices. At this time, the four spraying devices surround all the seedlings, which not only allows the mist of medicine to cover all the seedlings, but also allows windproof cloths to be hung on the support rods 1 and round pipes 3 of the four spraying devices. The windproof cloths are held taut by the hooks 106 on the support rods 1 and round pipes 3, thus protecting the seedlings inside the windproof cloths and preventing them from being blown over by strong winds and dying.
[0043] It is important to note that when using two sprayers as a group, if the branches and leaves of individual fruit trees in the orchard are growing particularly vigorously and extending outwards, the operator can adjust the sprayers on both sides of that tree, changing the two sprayers arranged in a straight line into an arc shape, such as... Figure 7 As shown, the spraying device extends outwards as the fruit tree grows, ensuring that the spraying device is always on the outside of the fruit tree and does not affect the spraying effect on the fruit tree.
[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
