Description

Technical Field

[0002] Tea leaves are obtained from tea trees. Generally, in the early stages of tea garden cultivation, during the tea tree growing season, when the soil is insufficiently fertile, and under the influence of climate change, in order to ensure the healthy growth of tea leaves, corresponding fertilization devices will be needed to supplement the tea trees with different elements.

[0003] When using the existing fertilization device for solid granular fertilizer, usually only the amount of fertilizer to be applied can be judged subjectively by humans, and the amount of fertilizer applied at a time cannot be accurately controlled. Too much fertilizer applied at a time can easily lead to waste of solid granular fertilizer, while too little fertilizer applied at a time can hardly ensure the fertilizer effectiveness at the fertilization location, thus making it difficult to ensure the reasonable utilization rate of solid granular fertilizer. To this end, we propose a fertilization device based on the supply of different elements for tea planting.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 , a fertilization device based on different elements for tea planting, comprising a storage bin 11, two handle bars 12 are fixedly connected to the outer surface of the storage bin 11, a guide pipe 13 is fixedly connected to the bottom end of the storage bin 11, and a quantitative feeding mechanism is arranged inside the storage bin 11;

[0035] The quantitative feeding mechanism includes an anti-blocking pre-feeding unit 21, which is arranged inside the storage bin 11. The anti-blocking pre-feeding unit 21 is used to properly stir the solid granular fertilizer in the storage bin 11 and ensure that a sufficient amount of solid granular fertilizer can be continuously stored in the guide pipe 13.

[0036] As a further limitation of the quantitative unloading mechanism of the present invention, the anti-blocking pre-unloading unit 21 includes a mounting shell 2101, the mounting shell 2101 is located above the storage bin 11, the outer surface of the mounting shell 2101 is in contact with the upper surface of the storage bin 11 and the inner wall of the storage bin 11 respectively, the inner wall of the mounting shell 2101 and the inner wall of the storage bin 11 are commonly threadedly connected with four mounting bolts 2102, the inner wall of the mounting shell 2101 is fixedly connected with a driving motor 2103, the output end of the driving motor 2103 is fixedly connected with a rotating rod 2104, the outer surface of the rotating rod 2104 and the inner wall of the mounting shell 2101 are commonly fixedly connected with a stabilizing bearing 2105, the outer surface of the rotating rod 2104 is fixedly connected with a connecting tube 2107, the outer surface of the connecting tube 2107 is fixedly connected with a plurality of identical stirring rods 2108, the bottom end of the rotating rod 2104 is fixedly connected with a spiral blade 2106, and the inner wall of the guide tube 13 is fixedly connected with a proximity switch 2109. By setting the mounting bolts 2102, the mounting shell 2101 can be fastened to the storage bin 11. At the same time, the proximity switch 2109 can monitor the material storage status of the material guide tube 13 in real time. The driving motor 2103 itself also has an angle encoder. When the material storage in the material guide tube 13 does not reach the position of the proximity switch 2109, the driving motor 2103 drives the spiral blade 2106 to rotate to guide the material.

[0037] See also Figure 1 and Figure 8 The outer surface of each handle rod 12 is fixedly connected with an anti-slip cover 2110, and the outer surface of each anti-slip cover 2110 is fixedly connected with a plurality of identical anti-slip bosses 2111. By providing the anti-slip cover 2110 and the anti-slip bosses 2111, the anti-slip property of the outer surface of the handle rod 12 can be increased, so that the user can control the entire fertilizing device more stably when holding the handle rod 12.

[0038] See also Figure 1 and Fig. 9 The dust plug 2113 is clamped inside the storage bin 11, and a plurality of identical air permeable cavities 2114 are evenly opened inside the dust plug 2113. The dust plug 2113 can block the feed inlet at the top of the storage bin 11, and prevent external foreign matter from entering the storage bin 11 to a certain extent. The air permeable cavity 2114 can connect the inside of the storage bin 11 and the outside of the dust plug 2113, so as to balance the air pressure inside and outside the storage bin 11, and prevent the solid granular fertilizer from being discharged into the storage bin 11 due to the different pressures inside and outside the storage bin 11.

[0039] See also Figure 1 The outer surface of the storage bin 11 is fixedly connected with a handle support 2115, and a grip 2116 is rotatably connected to the handle support 2115. By setting the handle support 2115 and the grip 2116, they can be used together to lift the entire fertilizing device, which is convenient for temporarily lifting and placing the entire fertilizing device.

[0040] See also Figure 3 The output end of the driving motor 2103 is fixedly connected with a first coupling 2112, and the output end of the first coupling 2112 is fixedly connected to the top of the rotating rod 2104. By setting the first coupling 2112, the connection between the output end of the driving motor 2103 and the rotating rod 2104 can be strengthened, thereby increasing the rotation stability of the rotating rod 2104.

[0041] A sufficient amount of solid granular fertilizer with multiple nutrient elements is loaded into the interior of the storage bin 11 through the top of the storage bin 11, and then the dust plug 2113 is plugged into the feed port at the top of the storage bin 11. When the proximity switch 2109 monitors in real time that the material storage height of the guide tube 13 is less than the position of the proximity switch 2109, the driving motor 2103 is controlled by its control components to drive the rotating rod 2104 and the spiral blade 2106 to rotate. The spiral blade 2106 rotates several times to guide the appropriate amount of solid granular fertilizer in the storage bin 11 to the guide tube 13. , thereby ensuring that a sufficient amount of temporary solid granular fertilizer is continuously stored in the guide tube 13. During this period, the rotating stirring rod 2108 properly stirs the solid granular fertilizer in the storage bin 11 to prevent the solid granular fertilizer from getting damp and agglomerating to a certain extent. The rotating spiral blades 2106 prevent the accumulation and jamming of solid granular fertilizer at the connection between the storage bin 11 and the guide tube 13, and at the same time gradually guide the solid granular fertilizer to the inside of the guide tube 13 to prevent the normal amount of solid granular fertilizer discharge from being affected by agglomeration or jamming of the solid granular fertilizer.

[0042] The quantitative feeding mechanism further includes a quantitative feeding unit 22, which is disposed at the lower part of the guide tube 13, and is used to quantitatively discharge the solid granular fertilizer temporarily stored in the guide tube 13;

[0043] The quantitative feeding unit 22 includes a transfer shaped tube 2201, which is located below the guide tube 13. The top of the transfer shaped tube 2201 is fixedly connected to the bottom end of the guide tube 13. The transfer shaped tube 2201 is provided with a branch tube. The inner wall of the branch tube is fixedly connected to a servo motor 2202. The output end of the servo motor 2202 is fixedly connected to a load-bearing rod 2203. The outer surface of the load-bearing rod 2203 is fixedly connected to a butterfly valve 2204. The outer surface of the load-bearing rod 2203 and the inner wall of the transfer shaped tube 2201 are jointly fixedly connected with two auxiliary bearings 2205. The upper surface of each handle rod 12 is fixedly connected to a feed switch 2206. The outer surface of the storage bin 11 is fixedly connected to a button controller 2207. The drive motor 2103, the proximity switch 2109, the servo motor 2202 and the two feed switches 2206 are all electrically connected to the button controller 2207 through wires. The servo motor 2202 has an internal angle encoder, so pressing any unloading switch 2206 can enable the button controller 2207 to control the servo motor 2202 to power on and drive the load-bearing rod 2203 and the butterfly valve 2204 to rotate the number of circles and angle set by the button controller 2207. At the same time, the button controller 2207 also takes into account the processing of the proximity switch 2109 signal, the power supply status of the drive motor 2103, the number of circles of the drive motor 2103, and the control of the rotation angle of the drive motor 2103.

[0044] See also Figure 5 The output end of the servo motor 2202 is fixedly connected with a second coupling 2208, and the second coupling 2208 is fixedly connected to one end of the bearing rod 2203. The second coupling 2208 can strengthen the connection between the output end of the servo motor 2202 and the bearing rod 2203, and the rotation is stable.

[0045] According to the amount of solid granular fertilizer required for each fertilization, the button controller 2207 is operated to set the number of single rotations and angles of the servo motor 2202, and the number of rotations and the rotation angle of the driving motor 2103 when it is powered on once. Then, when the proximity switch 2109 monitors that the material storage height of the guide tube 13 is less than the position of the proximity switch 2109, the button controller 2207 receives the signal of the proximity switch 2109, controls the driving motor 2103 to be powered on, and drives the rotating rod 2104 and the spiral blade 2106 to rotate by the set value. The spiral blade 2106 guides an appropriate amount of solid granular fertilizer in the storage bin 11 to the inside of the guide tube 13 according to a set number of circles and angles. Then, after holding the two handle rods 12 with both hands, press any one of the discharge switches 2206. The button controller 2207 controls the servo motor 2202 to energize and drive the load-bearing rod 2203 and the butterfly valve 2204 to rotate the set number of circles and angles. Then, the rotating butterfly valve 2204 discharges the solid granular fertilizer temporarily stored in the guide tube 13 in a quantitative manner to prevent excessive or insufficient discharge of solid granular fertilizer.

[0046] A soil discharge mechanism 3 is provided below the quantitative feeding unit 22. The soil discharge mechanism 3 is used in conjunction with the quantitative feeding mechanism. The soil discharge mechanism 3 is used to discharge the soil contaminated during fertilization in a timely manner to prevent the discharge of solid granular fertilizer from being blocked.

[0047] The soil discharge mechanism 3 includes a discharge head 301, which is located below the transfer special-shaped pipe 2201. The top of the discharge head 301 is fixedly connected to the bottom of the transfer special-shaped pipe 2201. The discharge head 301 is internally slidably connected with a discharge cone 302. The outer surface of the discharge cone 302 is fixedly connected with two symmetrically arranged sliding protrusions 303. Symmetrical vertical slots are arranged on the pipe wall of the discharge head 301. A guide rod 304 is fixed between the top and bottom of the vertical slot. The sliding protrusion 303 is slidably connected on the guide rod 304. A return spring 305 is sleeved on the guide rod 304 between the block 303 and the top of the vertical slot hole. One end of the sliding protrusion 303 extends out of the vertical slot hole and is fixedly connected to a fan-shaped limit plate 308. The bottom of the sliding protrusion 303 extending out of the vertical slot hole is fixed with an arc-shaped outer baffle 307, and the outer surface of the arc-shaped outer baffle 307 contacts the outer surface of the discharge head 301. The upper part of the sliding protrusion 303 located inside the discharge head 301 is fixed with an arc-shaped inner baffle 306, and the outer surface of the arc-shaped inner baffle 306 contacts the inner wall of the discharge head 301. The inside and outside of the discharge head 301 and the outer surface of the soil discharge cone 302 are all coated with anti-sticking coatings.

[0048] How to use this device: First, the user holds the two handle bars 12 with both hands respectively, and after lifting the entire fertilizing device to the place where fertilization is required, the device as a whole, under the condition of its own weight and gently pressing down the handle bar 12, makes the feeding head 301 insert into the soil around the tea tree and create a fertilizer pit, and at the same time the fan-shaped limit plate 308 contacts the soil surface, so that the sliding protrusion 303 and the feeding head 301 produce relative movement, that is, the sliding protrusion 303 slides up along the guide rod 304, the return spring 305 is compressed by the sliding protrusion 303, and the arc-shaped inner baffle plate 306 and the arc-shaped outer baffle plate 307 move up with the sliding protrusion 303, keep the vertical slot hole above the sliding protrusion 303 and the outer opening of the vertical slot hole closed, and are connected to the sliding protrusion 303. The soil discharge cone 302 is also driven to slide upward, so that the lower part of the soil discharge cone 302 is out of contact with the cone at the bottom of the feeding head 301, and a gap appears. Then, after pressing any feeding switch 2206, the quantitative feeding unit 22 will deliver a quantitative amount of solid granular fertilizer into the feeding head 301, and then the solid granular fertilizer above the feeding head 301 falls from the top of the feeding head 301 and flows out from the gap formed by the upward movement of the soil discharge cone 302. After the feeding switch 2206 returns to its position, the feeding stops and one fertilization is completed. When the fertilization is completed, the feeding head 301 is pulled out of the soil, and the return spring 305 rebounds the sliding protrusion 303 and the soil discharge cone 302, so that the soil discharge cone 302 discharges the soil that may be stuck to the bottom outlet of the feeding head 301. The arc-shaped inner baffle plate 306 prevents the solid granular fertilizer falling from the discharge head 301 from overflowing from the vertical slot (although overflow does not affect the fertilizer efficiency, the fertilizer may fall on the ground surface, and the fertilizer that falls on the ground surface is slowly absorbed by the roots), and the arc-shaped outer baffle plate 307 effectively prevents soil from entering the discharge head 301 from the opening below the sliding protrusion 303, preventing subsequent solid granular fertilizers from being blocked and affecting the discharge of solid granular fertilizers due to the soil blocking the discharge head 301, so that the discharge of solid granular fertilizers is smooth.
