Description

Technical Field

[0001] This utility model relates to the field of greening construction technology, specifically to an automatic irrigation and fertilization device for green seedlings. Background Technology

[0002] Green seedlings refer to flowering plants used for greening the environment. Green seedlings are artificially cultivated and have specific morphological characteristics. They are commonly used in landscaping, roadside greening, park greening, residential area greening, and other natural, living, and public environments. They can improve air quality, add color to life, and also relieve people's work and life stress, making them feel happy. Green seedlings are an important part of greening projects. After the trees are planted, automatic irrigation and fertilization devices are needed.

[0003] The existing automatic irrigation and fertilization device mainly consists of a trolley, a fertilizer pump, and a fertilizer tank. After pushing the trolley past the seedling planting location, the fertilizer pump is activated to spray fertilizer onto the planting soil. It is convenient and quick. However, during the long-term fertilization process, the fertilizer inside the fertilizer tank will gradually settle into the tank, resulting in different nutrient contents of the sprayed fertilizer, which may cause some green seedlings to suffer from nutrient deficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic irrigation and fertilization device for green seedlings, in order to solve the problem mentioned in the background art that during the long-term fertilization process, the fertilizer inside the fertilizer tank will gradually settle into the tank, resulting in different nutrient contents of the sprayed fertilizer, which causes some green seedlings to suffer from nutrient deficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic irrigation and fertilization device for green seedlings, comprising a trolley, a fertilizer tank, and a mixing unit. The fertilizer tank is connected above the trolley, and the mixing unit is positioned above the fertilizer tank. The mixing unit has a mounting frame connected above the fertilizer tank, and a motor is connected above the mounting frame. A rotating rod is connected to the output end of the motor. A sliding sleeve is slidably connected to the mounting frame inside the fertilizer tank, and sliding protrusions are connected to both sides of the mounting frame, with the sliding protrusions slidably connected to the sliding sleeve. A spring is connected above the sliding protrusion, and the top of the spring is connected to the inner wall of the sliding sleeve. A mixing rod is connected to the outer wall of the sliding sleeve, and a roller is connected to the top of the sliding sleeve. A concave-convex ring is connected to the inner side of the mounting frame, with the bottom of the concave-convex ring fitting against the roller. The roller rotates around the rotating rod as a center, and under the influence of the concave-convex ring, it drives the sliding sleeve to move vertically.

[0006] By adopting the above technical solution, the starting motor drives the rotating rod to rotate, and the rotating rod drives the stirring rod on the outside of the sliding sleeve to rotate, thus stirring the fertilizer. During the rotation of the sliding sleeve, the rollers and the concave and convex rings will make vertical reciprocating motion, which improves the stirring effect of the stirring rod on the fertilizer. The stirring rod, which floats up and down and rotates, fully stirs the fertilizer, reducing the situation where fertilizer substances settle at the bottom of the tank.

[0007] Preferably, the stirring part also has protective doors that are installed on both sides of the mounting frame via hinges. The mounting frame is connected to fixing blocks on both sides, and the fixing blocks are rotatably connected to fixing rods, with the fixing rods fitting against the protective doors.

[0008] By adopting the above technical solution, the protective door can be opened or closed by rotating the fixed rod, which facilitates the staff to perform regular maintenance on the internal structure of the installation frame.

[0009] Preferably, a sliding rod is fixedly connected to the inner wall of the sliding sleeve, and the sliding rod is slidably connected to the sliding protrusion, and the sliding rod passes through the hole formed in the center of the spring.

[0010] By adopting the above technical solution, the spring can be limited by the sliding rod, reducing the occurrence of spring deformation and misalignment.

[0011] Preferably, there are two sets of rollers, and both sets of rollers are in contact with the concave and convex rings.

[0012] By adopting the above technical solution, the sliding sleeve can be better propelled to move vertically by setting two sets of rollers.

[0013] Preferably, the bottom of the rotating rod is rotatably connected to the bottom of the fertilizer tank, and the mounting frame is rotatably connected to the rotating rod.

[0014] By adopting the above technical solution, the rotating rod can be supported by the combination of the mounting frame and the fertilizer tank, thereby improving the stability of the rotating rod during rotation.

[0015] Preferably, the fertilizer tank has a hole at the top, and the sliding sleeve passes through the hole in the fertilizer tank, with a gap between the sliding sleeve and the inner wall of the hole in the fertilizer tank.

[0016] By adopting the above technical solution, damage to the sliding sleeve during its rotation can be avoided.

[0017] Preferably, the fixing rod is provided with a rubber pad on one side of the protective door, and the rubber pad is in contact with the protective door.

[0018] By adopting the above technical solution, the fixing rod is fixed by the friction between the rubber pad and the protective door, thereby improving the fixing effect of the fixing rod on the protective door.

[0019] Preferably, a limiting protrusion is fixedly connected inside the mounting frame, and the limiting protrusion fits into the protective door.

[0020] By adopting the above technical solution, the limit protrusion can buffer the protective door when it is closed, thus avoiding damage to the hinges caused by excessive door movement.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) By starting the motor, the rotating rod is driven to rotate. The rotating rod drives the stirring rod on the outside of the sliding sleeve to rotate and stir the fertilizer. During the rotation of the sliding sleeve, the roller and the concave and convex ring will make vertical reciprocating motion, which improves the stirring effect of the stirring rod on the fertilizer. The fertilizer is fully stirred by the up-and-down floating and rotating stirring rod, reducing the situation of fertilizer material settling at the bottom of the tank.

[0023] (2) The protective door can be opened or closed by rotating the fixed rod, which makes it convenient for staff to perform regular maintenance on the internal structure of the installation frame. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0032] Example 1

[0033] Please see Figure 1-5 This embodiment provides a technical solution: an automatic irrigation and fertilization device for green seedlings, including a trolley 1, a fertilizer tank 2, and a mixing unit 3. The trolley 1 is equipped with a mobile power supply, a fertilizer pump, and a nozzle. By activating the fertilizer pump, fertilizer can be sprayed through the nozzle. The fertilizer tank 2 is connected to the trolley 1 via bolts, and its outlet is connected to the fertilizer pump via a connecting pipe. The mixing unit 3 is positioned above the fertilizer tank 2 and has a mounting frame 301 connected to the top of the fertilizer tank 2. The mounting frame 301 is fixedly connected to the top of the fertilizer tank 2 via bolts. A motor 302 is connected to the top of the mounting frame 301. 02 is bolted to the top of the mounting frame 301 for easy disassembly or installation by workers. The motor 302 is electrically connected to the mobile power supply of the trolley 1. The output end of the motor 302 is connected to a rotating rod 303, which is bolted to the output end of the mounting frame 301. When the motor 302 is working, it can drive the mounting frame 301 to rotate. The mounting frame 301 is slidably connected to a sliding sleeve 305 inside the fertilizer tank 2. Sliding protrusions 304 are connected to both sides of the mounting frame 301 and are slidably connected to the sliding sleeve 305. The sliding protrusions 304 are welded to the rotating rod 303 to improve the stability of the overall structure.

[0034] A spring 307 is connected above the sliding protrusion 304, and the top of the spring 307 is connected to the inner wall of the sliding sleeve 305. The spring 307 is connected to the sliding sleeve 305 and the sliding protrusion 304 by a snap fastener. The spring 307... Figure 3The diagram shows a slightly compressed deformation state. A stirring rod 306 is connected to the outer wall of the sliding sleeve 305. The stirring rod 306 is connected to the sliding sleeve 305 by bolts. A roller 309 is connected to the top of the sliding sleeve 305 by bolts. A concave-convex ring 310 is connected to the inner side of the mounting frame 301 by bolts. The concave-convex ring 310 is connected to the mounting frame 301 by bolts, and the bottom of the concave-convex ring 310 is in contact with the roller 309. During the rotation of the roller 309, it will move vertically under the influence of the concave-convex ring 310. The roller 309 rotates around the rotating rod 303 as the center and drives the sliding sleeve 305 to move vertically under the influence of the concave-convex ring 310.

[0035] Example 2

[0036] Please see Figure 1-5 The stirring unit 3 also has protective doors 311 that are hinged to both sides of the mounting frame 301. Fixing blocks 312 are connected to both sides of the mounting frame 301. The fixing blocks 312 are bolted to both sides of the mounting frame 301, making it easy for workers to disassemble or install the fixing blocks 312. The fixing blocks 312 are rotatably connected to fixing rods 313. The fixing rods 313 are made of stainless steel to prevent rusting during long-term use. The fixing rods 313 fit against the protective doors 311, which can be used to fix the protective doors 311. This allows workers to open the protective doors 311 to maintain the internal structure of the mounting frame 301. A sliding rod 308 is fixedly connected to the inner wall of the sliding sleeve 305. The sliding rod 308 is slidably connected to the sliding protrusion 304. The sliding rod 308 passes through the hole formed in the center of the spring 307. The sliding rod 308 can limit the movement of the spring 307, reducing the occurrence of deformation and misalignment of the spring 307.

[0037] Two sets of rollers 309 are provided, and both sets of rollers 309 are in contact with the concave and convex rings 310. The two sets of rollers 309 allow for better vertical movement of the sliding sleeve 305. The bottom of the rotating rod 303 is rotatably connected to the bottom of the fertilizer tank 2, and the mounting frame 301 is rotatably connected to the rotating rod 303. The mounting frame 301 and the fertilizer tank 2 cooperate to support the rotating rod 303, improving its stability during rotation. A hole is provided at the top of the fertilizer tank 2, and the sliding sleeve 305 passes through this hole. A gap exists between the sliding sleeve 305 and the inner wall of the hole in the fertilizer tank 2 to prevent slippage. During the rotation of sleeve 305, damage to sliding sleeve 305 is caused. The fixing rod 313 is provided with a rubber pad on one side of the protective door 311, and the rubber pad is in contact with the protective door 311. The fixing rod 313 is fixed by the friction between the rubber pad and the protective door 311, thereby improving the fixing effect of the fixing rod 313 on the protective door 311. The mounting frame 301 is fixedly connected with a limiting protrusion 314, and the limiting protrusion 314 is in contact with the protective door 311. By providing the limiting protrusion 314, the protective door 311 can be buffered when closed, avoiding the situation where the hinge is damaged due to excessive movement of the protective door 311.

[0038] Working principle: First, when it is necessary to stir the fertilizer inside the fertilizer tank 2, the motor 302 is started. The motor 302 drives the rotating rod 303 to rotate. Since the sliding protrusion 304 of the rotating rod 303 is slidably connected to the sliding sleeve 305, and there are two sets of sliding protrusions 304, and both sets of sliding protrusions 304 are slidably connected to the sliding sleeve 305, the rotation of the rotating rod 303 will drive the sliding sleeve 305 to rotate. The rotation of the sliding sleeve 305 will drive the stirring rod 306 to rotate, and the rotation of the stirring rod 306 will stir the fertilizer inside the fertilizer tank 2.

[0039] Secondly, during the rotation of the sliding sleeve 305, the roller 309 will also rotate. Since the roller 309 is in contact with the bottom of the concave-convex ring 310, the roller 309 will move to the convex position at the bottom of the concave-convex ring 310 during the rotation. When the roller 309 moves to the convex position of the concave-convex ring 310, the downward movement of the roller 309 will push the sliding sleeve 305 downward. The downward movement of the sliding sleeve 305 will cause the spring 307 to deform, and the movement of the sliding sleeve 305 will drive the stirring rod 306 downward. When the roller 309 rotates to the concave position of the concave-convex ring 310, the spring 307 will restore its deformation and push the sliding sleeve 305 downward. The movement of the sliding sleeve 305 will drive the stirring rod 306 upward. Therefore, the stirring rod 306 will perform up-and-down reciprocating motion, thereby improving the stirring effect of the stirring rod 306 on the fertilizer and reducing the situation of fertilizer components settling to the bottom.
