Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer spraying devices, specifically to a foliar spraying device for micronutrient liquid fertilizer. Background Technology

[0002] The micronutrient liquid fertilizer foliar spraying device connects modern agricultural fertilization technology with precision agriculture equipment. It mainly serves to solve the pain points of traditional fertilization, improve crop quality and resource utilization efficiency, and is widely used in field crops, cash crops, facility agriculture and other fields to spray liquid fertilizer on the leaves of plants such as vegetable greenhouses.

[0003] In existing technological applications, foliar fertilization in vegetable greenhouses typically involves the following method: a support track is pre-installed on the top of the greenhouse, and the liquid fertilizer spraying equipment is mounted on a moving mechanism. A motor drives the moving mechanism, which in turn moves the rollers at its bottom along a pre-defined path on the support track, allowing the spraying equipment to operate directly above the vegetable leaves and complete the liquid fertilizer application. However, this method has some drawbacks: traditional liquid fertilizer spraying equipment often uses vertically fixed spray heads, limiting the spraying range to a small area directly below the spray head. This can result in some vegetable leaves not being covered by the liquid fertilizer, affecting the uniformity and effectiveness of the fertilization. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a foliar spraying device for micronutrient liquid fertilizer, which can effectively solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a foliar spraying device for micronutrient liquid fertilizer, including a support guide plate and a moving mechanism set on the support guide plate. The moving mechanism is equipped with rollers inside, a base plate is fixedly installed at the lower end of the moving mechanism, a connecting plate is fixedly installed at the lower end of the base plate, a support plate is fixedly installed at the lower end of the connecting plate, a bearing plate is fixedly installed inside the lower end of the support plate, and multiple sets of docking valve pipes are fixedly sleeved inside the bearing plate. An angle rotation component is provided at the lower end of the support plate. The angle rotation assembly includes an electric push rod and an L-shaped plate, one side of which is fixedly connected to one side of a support plate.

[0006] Furthermore, a track groove is provided on the lower part of one side of the L-shaped plate, and a hinge block is fixedly installed on the lower end of each of the bearing plates. A fastening nut is fixedly installed on one end of each of the multiple sets of docking valve pipes, a hose is fixedly installed on one end of the fastening nut, a spray head is fixedly installed on one end of the hose, a connecting sleeve is fixedly sleeved on the upper end of the spray head, and a rotating column is fixedly sleeved inside the upper end of the connecting sleeve.

[0007] Furthermore, a movable bolt is rotatably connected to the upper end of the rotating column, and the rotating column is fixedly installed on the hinge block by the movable bolt. A gear is fixedly installed on one side of the hinge block.

[0008] Furthermore, a sliding rod is slidably fitted inside the track groove of the L-shaped plate, and a straight toothed rod is fixedly connected to one side of the sliding rod.

[0009] Furthermore, the upper end of the spur bar is engaged with the outside of the gear.

[0010] Furthermore, one end of the electric push rod is fixedly installed on one end of the bracket plate, and the push rod of the electric push rod is fixedly installed on one end of the sliding rod.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model utilizes an electric push rod, a spur gear, a gear, a hinge block, and a movable bolt in a rotating angle assembly. The electric push rod drives a sliding rod to slide back and forth along the track groove of an L-shaped plate. The sliding rod drives the spur gear to move back and forth, and the spur gear meshes with and drives the gear to rotate in a radius. The gear drives the hinge block to rotate synchronously, which in turn drives the spray head to swing back and forth around the movable bolt via a rotating column and connecting sleeve. Compared to traditional liquid fertilizer spraying equipment where the spray heads are mostly fixed and vertically downward, this invention allows liquid fertilizer to be sprayed in a continuous swinging motion within a certain angle range, rather than being limited to a fixed direction. This ensures that the vegetable leaves in the target area can be more fully covered by the fertilizer, preventing some vegetable leaves from being left uncovered by the liquid fertilizer and thus affecting the uniformity and effectiveness of liquid fertilization.

[0012] 2. At the same time, the profile plate is provided with a track groove, and the sliding rod can slide back and forth along the track groove 53, thereby ensuring that the spur gear can move stably in a straight line direction. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments. Example 1:

[0018] Reference Figures 1 to 4This first embodiment of the present invention discloses a foliar spraying device for micronutrient liquid fertilizer, including a supporting guide rail plate 1 and a moving mechanism 2 mounted on the supporting guide rail plate 1. The moving mechanism 2 has rollers 21 inside, a base plate 22 fixedly mounted at its lower end, a connecting plate 3 fixedly mounted at its lower end, a support plate 4 fixedly mounted at its lower end, a bearing plate 6 fixedly mounted inside the lower end of the support plate 4, and multiple sets of connecting valve pipes 72 fixedly sleeved inside the bearing plate 6. An angle rotation component 5 is provided at the lower end of the support plate 4 for rotating the spray head. The large liquid fertilizer coverage area is achieved by the moving mechanism 2 rolling on the support guide plate 1 via internal rollers 21, which drives the entire device to move on the guide rail, so that the spray head 7 of the docking valve pipe 72 on the bearing plate 6 is aligned with the plant leaves to be sprayed. The moving mechanism 2, rollers, and support guide plate are all existing technologies and will not be described in detail here. The moving mechanism 2 usually uses the rolling between the rollers 21 and the support guide plate 1 to achieve movement. The rollers 21 roll on the track of the support guide plate 1 under the drive of the motor. The support guide plate 1 provides support and guidance for the rollers 21, so that the moving mechanism 2 can move smoothly along the predetermined path. The angle rotation assembly 5 includes an electric push rod 51 and an L-shaped plate 52. The electric push rod 51 serves as a driving component and can output thrust or pull force through its extension and retraction. One side of the L-shaped plate 52 is fixedly connected to one side of the bearing plate 6. A track groove 53 is provided at the lower part of the inner side of the L-shaped plate 52. A hinge block 57 is fixedly installed at the lower end of the bearing plate 6. A fastening nut 73 is fixedly installed at one end of multiple sets of docking valve pipes 72. One end of the docking valve pipe 72 is a pipe for installing an external pipe. The external pipe is connected to an external liquid fertilizer tank. The external liquid fertilizer is further transported by the pump body to the docking valve pipe and hose, so that the liquid fertilizer can be sprayed or applied through the spray head. A hose 71 is fixedly installed at one end of the fastening nut 73. A spray head 7 is fixedly installed at one end of the hose 71. A connecting sleeve 59 is fixedly sleeved on the upper end of the spray head 7. A rotating column 58 is fixedly sleeved inside the upper end of the connecting sleeve 59.

[0019] The upper end of the rotating column 58 is rotatably connected to a movable bolt. The rotating column 58 is fixedly installed on the hinge block 57 by the movable bolt. The rotating column and the hinge block are aligned, and the movable bolt rotates through the upper end of the rotating column. The hinge block and the movable bolt are fixed at both ends and do not rotate. A gear 56 is fixedly installed on one side of the hinge block 57. A sliding rod 54 is slidably fitted inside the track groove 53 of the L-shaped plate 52. A spur gear 55 is fixedly connected to one side of the sliding rod 54. The upper end of the spur gear 55 is meshed with the outside of the gear 56. One end of the electric push rod 51 is fixedly installed on one end of the bracket plate 4. The push rod of the electric push rod 51 is fixedly installed on one end of the sliding rod 54.

[0020] The remaining structure is the same as that in Example 1.

[0021] The workflow of this utility model is as follows: First, the pump starts working and pressurizes the liquid fertilizer in the external liquid fertilizer tank. The fertilizer passes through the external pipe and the docking valve pipe 72 into the hose 71, and finally reaches the spray head 7. At this time, the spray head 7 starts to spray out liquid fertilizer. The moving mechanism 2 usually moves by rolling between the roller 21 and the support guide plate 1. The roller 21 rolls on the track of the support guide plate 1 under the drive of the motor. The support guide plate 1 provides support and guidance for the roller 21, so that the moving mechanism 2 can move smoothly along the predetermined path, so that the spray head 7 of the docking valve pipe 72 on the bearing plate 6 is aligned with the vegetable leaves to be sprayed. Secondly, the electric push rod 51 is activated. When the spraying range of the spray head 7 is increased, the electric push rod 51 is extended or retracted, which drives the sliding rod 54 to slide back and forth along the track groove 53 of the L-shaped plate 52. The sliding rod 54 drives the spur gear 55 to move back and forth. The spur gear 55 meshes with and drives the gear 56 to rotate in a radius. The gear 56 drives the hinge block 57 to rotate synchronously. Then, through the rotating column 58 and the connecting sleeve 59, the spray head 7 is driven to swing back and forth around the movable bolt, so that the spray head 7 can rotate at an angle to spray liquid fertilizer, ensuring that the liquid fertilizer evenly covers the target area, thereby increasing the area of ​​liquid fertilizer spraying on the vegetable leaves.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
