Description

Technical Field

[0001] This utility model belongs to the field of seedling planting technology, specifically relating to a fertilizer applicator for Rhododendron simsii seedlings. Background Technology

[0002] Rhododendron simsii, an evergreen shrub or small tree with high ornamental value and economic potential, is commonly used in landscaping and specialty seedling cultivation. Its growth cycle is relatively long, especially during seedling cultivation and mature plant maintenance, requiring timely and appropriate fertilization to meet nutrient needs and ensure healthy growth and good morphology. To achieve precise and efficient nutrient supply and reduce fertilizer waste and environmental pollution, specialized fertilization equipment has become an indispensable tool in seedling maintenance and management. Existing fertilization equipment is mainly designed for fertilizers in different physical forms, such as solid granular fertilizers (e.g., slow-release fertilizers, compound fertilizers) and liquid fertilizers (e.g., water-soluble fertilizers, nutrient solutions).

[0003] However, current fertilizer applicators on the market generally suffer from a significant technical flaw: separate specialized equipment with drastically different structures and working principles must be used for solid and liquid fertilizers. This not only increases equipment purchase costs and storage space requirements but also makes the operation cumbersome and time-consuming. Therefore, there is an urgent need to develop a fertilizer applicator for Rhododendron simsii seedlings that can apply both solid and liquid fertilizers, to solve the problems of inconvenience, low efficiency, and increased costs caused by the difference in fertilizer forms in existing technologies. Utility Model Content

[0004] The purpose of this invention is to propose a fertilizer applicator for Rhododendron simsii seedlings that can be used to apply both solid and liquid fertilizers.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A fertilizer applicator for Rhododendron simsii seedlings includes a storage box for storing solid or liquid fertilizer, a fertilizer application tube, and hand handles and a soil-removing shovel fixedly installed at both ends of the fertilizer application tube. The storage box has a first discharge port and a second discharge port at its lower end. The storage box is equipped with a sealing device that can block the first or second discharge port. Solid fertilizer conveying devices and liquid fertilizer conveying devices are respectively installed at the first and second discharge ports at the lower end of the storage box. Both solid fertilizer conveying devices and liquid fertilizer conveying devices are connected to the fertilizer application tube. The storage box has an inlet at its upper end, and a movable cover is movably installed at the inlet. A battery and two shoulder straps are fixedly installed on the storage box. A rotating baffle is rotatably installed at the end of the fertilizer application tube away from the hand handle, and a torsion spring is provided at the rotatable connection between the rotating baffle and the fertilizer application tube.

[0007] Further specifying, the solid fertilizer conveying component includes a connecting pipe fixedly connected between the first discharge port and the fertilizer application pipe, a flexible auger passing through the connecting pipe, and a drive motor. The drive motor is fixedly mounted on the fertilizer application pipe, and its output shaft passes through the fertilizer application pipe and is fixedly connected to the flexible auger. A rotating sealing ring is provided at the junction of the drive motor output shaft and the fertilizer application pipe. With this structural design, when the sealing component blocks the second discharge port, the drive motor drives the flexible auger to rotate, thereby conveying the solid fertilizer in the storage tank into the fertilizer application pipe.

[0008] Further specifying, the liquid fertilizer conveying device includes a bent pipe fixedly connected to the second outlet, a liquid pump fixedly installed at the end of the bent pipe, and a conveying pipe fixedly installed at the output end of the liquid pump. A filter screen is fixedly installed at one end of the bent pipe at the second outlet, and the end of the conveying pipe is fixedly connected to the fertilizer application pipe. Both the connecting pipe and the conveying pipe are flexible hoses. With this structural design, when the sealing component blocks the first outlet, the liquid pump operates, allowing the liquid fertilizer in the storage tank to be conveyed through the conveying pipe into the fertilizer application pipe, ultimately flowing to the seedlings.

[0009] Furthermore, the handheld handle is equipped with two control buttons, which are electrically connected to the battery, drive motor, and liquid pump. This structural design allows for control of the drive motor and liquid pump via the two control buttons, making it more convenient to use.

[0010] Further specifying, the end of the delivery pipe near the fertilizer application pipe is a rigid pipe, with a fixing rod fixedly installed inside. A mounting column is fixedly installed on the fixing rod near the fertilizer application pipe, and a baffle plate is movably installed on the mounting column. A limiting end is fixedly installed at the end of the mounting column, and an elastic sleeve is fitted on the mounting column between the baffle plate and the limiting end. With this structural design, when the liquid pump is working, the baffle plate will be in an open state under the action of force. When the liquid pump stops working, the elastic sleeve applies an elastic force to the baffle plate, which can push the baffle plate back to its initial state, preventing solid fertilizer from entering the delivery pipe and affecting the use of the fertilizer delivery components.

[0011] Further specifying, the sealing component includes a rotating column rotatably mounted at the lower end of the storage box, a sealing strip and a knob respectively fixedly mounted at the upper and lower ends of the rotating column, the sealing strip being movably mounted on the bottom of the inner wall of the storage box, the knob having an arrow marking, a rotating sealing ring at the junction of the rotating column and the storage box, and two limiting blocks fixedly mounted on the bottom of the inner wall of the storage box. When the sealing strip abuts against one of the limiting blocks, the sealing strip blocks either the first or second discharge port. This structural design is simple and easy to use.

[0012] The utility model adopting the above technical solution has the following advantages:

[0013] This utility model uses a sealing component to block either the first or second discharge port, allowing the storage box to work with either a solid fertilizer conveyor or a liquid fertilizer conveyor to transport solid or liquid fertilizer. Users can complete the fertilization of solid or liquid fertilizer without having to carry two different types of fertilization tools. Furthermore, this seedling planting fertilizer applicator occupies little space and is more convenient to store. Attached Figure Description

[0039] The solid fertilizer conveying component 5 includes a connecting pipe 51 fixedly connected between the first discharge port 11 and the fertilizer pipe 2, a flexible auger 52 passing through the connecting pipe 51, and a drive motor 53. The drive motor 53 is fixedly installed on the fertilizer pipe 2. The output shaft of the drive motor 53 passes through the fertilizer pipe 2 and is fixedly connected to the flexible auger 52. A rotating sealing ring is provided at the junction of the output shaft of the drive motor 53 and the fertilizer pipe 2.

[0040] The liquid fertilizer conveying component 6 includes a bent pipe 61 fixedly connected to the second outlet 12, a liquid pump 62 fixedly installed at the end of the bent pipe 61, and a conveying pipe 63 fixedly installed at the output end of the liquid pump 62. A filter screen 64 is fixedly installed at one end of the bent pipe 61 located at the second outlet 12. The filter screen 64 can block large debris to prevent large debris from entering the bent pipe 61 or the liquid pump 62 and causing damage to the liquid pump 62. The end of the conveying pipe 63 is fixedly connected to the fertilizer pipe 2. Both the connecting pipe 51 and the conveying pipe 63 are flexible hoses. Two control buttons 31 are provided on the hand handle 3. The two control buttons 31 are electrically connected to the battery 14, the drive motor 53 and the liquid pump 62.

The movable cover 13 can be opened to pour the liquid fertilizer into the storage box 1. Then the movable cover 13 is closed. After the user carries the storage box 1 on his back, he holds the handle 3 with one hand and can move the soil at the seedling with the soil shovel 4. At this time, the liquid pump 62 is controlled by the control button 31. The liquid pump 62 can transport the liquid fertilizer in the storage box 1 to the fertilizer pipe 2 through the delivery pipe 63. During the delivery, the baffle 633 will move towards the limiting end 634 under the action of force, so that the liquid fertilizer can enter smoothly and finally flow to the soil at the seedling through the end of the fertilizer pipe 2.

[0045] When solid fertilizer needs to be applied, turn knob 72 so that the arrow indicates the second outlet 12. At this time, the sealing strip 71 will block the second outlet 12. After the solid fertilizer is poured in, control the drive motor 53 to work through control button 31. The flexible auger 52 will transport the solid fertilizer in the storage box 1 to the outside through the fertilizer application pipe 2. (During this process, the baffle plate 633 will abut against the fixed rod 631 under the elastic force of the elastic sleeve 635. The baffle plate 633 will block the end of the delivery pipe 63 to prevent solid fertilizer from entering and affecting the use of the liquid fertilizer delivery component 6) until the fertilizer reaches the designated area and the fertilization work is completed.
