Description

[0001] The invention relates to the field of fertilization, and in particular to a magnesium fertilizer application device and an application method for promoting carbon fixation and emission reduction in tea garden soil. Background Art

[0002] The acidity, high heat, high humidity and high fertilization of tea garden soils have led to serious losses of soil organic carbon (SOC). Magnesium, as an essential nutrient for plants, plays an important role in the production and distribution of photosynthesis and carbon assimilation products. Studies have shown that increasing the application of magnesium fertilizers can not only affect plant growth and carbon input, but also change the formation and stability of SOC by changing the structure of soil microbial communities and enhancing the activity and function of microbial enzymes.

[0003] After searching the publication (announcement) number: CN214507956U, a fertilizer applicator for agricultural planting is disclosed, which relates to the field of agricultural related equipment. The fertilizer applicator for agricultural planting includes a fertilizer applicator body, a through hole is opened at the bottom of the fertilizer applicator body, a fixed frame is fixedly connected to the bottom of the fertilizer applicator body, a rotating shaft is rotatably connected to the fixed frame, wheels are fixedly connected to both ends of the rotating shaft, two bevel gears are fixedly connected to the rotating shaft, a support rod is rotatably connected inside the fertilizer applicator body, the support rod passes through the fertilizer applicator body, one end of the support rod is fixedly connected to a bevel gear, and the bevel gear is meshed with the bevel gear.

[0004] Although the above scheme can drive the stirring blades to rotate by the movement of the fertilizer spreader, the discharge port of the fertilizer spreader is always in an open state at this time, so that a variety of fertilizers are discharged from the fertilizer spreader before being fully stirred. In addition, when fertilizing tea gardens in the mountains, the fertilizer spreader will move on rugged mountain terrain, which will cause the fertilizer spreader to shake and bump during movement, greatly reducing its driving stability. Summary of the invention

[0024] S1. Batching: Weigh a certain amount of diammonium phosphate, urea, potassium sulfate and magnesium sulfate, and transport them to a mixing box, wherein the weight ratio of diammonium phosphate, urea, potassium sulfate and magnesium sulfate is 23:59:25:22;

[0025] S2, mixing: start the driving motor to drive the stirring rod to rotate. At this time, the electric push rod fixes the limit rod, the discharge port is in a sealed state, and the stirring rod will hit the triangular block during the rotation process;

[0026] S3, unloading and remixing: start the electric push rod to separate it from the limit rod, then energize the electromagnet to make it absorb the guide block, so that the fertilizer inside the mixing box is transported to the storage barrel, and then repeat the operations of S1 and S2 to make the mixing box full of mixed fertilizer;

[0027] S4. Fertilization: Move the trolley to the tea garden and start the electric telescopic rod so that it drives the opening of the discharge pipe to face the fertilizer ditch, then open the discharge port and start the air pump. When the trolley is pushed, the fertilizer will be transported to the fertilization ditch through the discharge pipe. When the trolley vibrates, it will drive the storage barrel to move up and down through the connecting spring, so that the two transmission rods drive the slider to slide inside the transmission rod, thereby driving the drive shaft to rotate, thereby driving the breaking rod and the push rod to do pendulum motion.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the present invention, the raw materials of each component are transported into the mixing box, and then the driving motor is started to drive the stirring rod to rotate. At this time, the electric push rod fixes the limit rod, and the discharge port is in a sealed state. The raw materials are mixed by the stirring rod. When the stirring rod is rotating, it will hit the triangular block to make the inside of the mixing box vibrate, so as to loosen the materials attached to the box wall and the stirring rod, thereby reducing the accumulation and adhesion of the materials.

[0030] 2. In the present invention, the electric push rod is started to separate from the limit rod, and then the electromagnet is energized. At this time, the electromagnet will have magnetic force, thereby adsorbing the guide block, and then driving the guide block to move upward, thereby driving the connecting block and the sealing block to move upward, thereby opening the discharge port, and at this time the fertilizer inside the mixing box will be transported to the storage barrel.

[0031] 3. In the present invention, by turning off the electromagnet and the drive motor, the permanent magnet will be adsorbed on the outer surface of the triangular block, thereby preventing the stirring rod from being vertically located directly above the seal, thereby avoiding interference of the stirring rod with the seal.

[0032] 4. In the present invention, by starting the electric telescopic rod, it drives the feed pipe to move, and makes the opening of the feed pipe face the fertilizer ditch, then opens the discharge port and starts the air pump, and pushes the cart to move in the tea garden. At this time, the fertilizer will be transported to the fertilizer ditch through the feed pipe. Because the road in the tea garden is uneven, the cart will vibrate during the movement. At this time, through the cooperation of the fixed sleeve and the slide rod, and under the action of the connecting spring, the storage barrel makes a vertical circular motion. At this time, the slider will slide inside the convex groove, thereby driving the transmission rod to move, and then driving the drive shaft to rotate. When the drive shaft rotates, it will drive the breaking rod and the push rod to do a pendulum motion, so that the breaking rod breaks the fertilizer, and the push rod will push the guide block up and down during the rotation, so as to open the discharge port, so that the fertilizer inside the mixing box can be continuously transported to the storage barrel.

DETAILED DESCRIPTION

[0043] Example 1: Please refer to Figure 1-Figure 8 As shown, the present invention is a magnesium fertilizer application device for promoting carbon fixation and emission reduction in tea garden soil, comprising:

[0044] A trolley 1, a material storage barrel 2 is arranged on the top of the trolley 1, a material discharge mechanism is fixedly connected to the bottom of the material storage barrel 2, and a mixing box 4 is fixedly connected to the top of the material storage barrel 2;

[0045] The discharging mechanism includes a discharging pipe 301 fixedly connected to the bottom of the storage barrel 2, an air pump 302 fixedly connected to the bottom of the trolley 1, an electric telescopic rod 303 fixedly connected to the outer wall of the discharging pipe 301, and a discharge pipe 304 fixedly connected to the output end of the electric telescopic rod 303, wherein the air pump 302 is connected to the inside of the discharging pipe 301 through a hose, the discharge pipe 304 is sleeved on the outer surface of the discharging pipe 301, and the opening of the discharge pipe 304 is opened on the lower side wall, and the inner diameter of the discharge pipe 304 is equal to the outer diameter of the discharging pipe 301;

[0046] The dispersing mechanism includes a driving shaft 504 that penetrates the side wall of the storage barrel 2 and is rotatably connected to the side wall, and a transmission rod 505 that is fixedly connected to the outer side wall of the driving shaft 504 and is used to drive the driving shaft 504 to rotate;

[0047] The stirring mechanism includes a permanent magnet 604 movably disposed inside the mixing box 4, and a triangular block 605 fixedly connected to the inner wall of the mixing box 4;

[0048] The separation mechanism includes a discharge port 401 opened on the bottom plate of the mixing box 4 and a sealing member 701 penetrating the discharge port 401 for sealing the discharge port 401 .

[0049] The stirring mechanism also includes a driving motor 601 fixedly connected to the outer wall of the mixing box 4, a driven shaft 602 fixedly connected to the output end of the driving motor 601, and a stirring rod 603 fixedly connected to the outer wall of the driven shaft 602;

[0050] The side wall of the permanent magnet 604 is hinged to the end face of the stirring rod 603, and the driven shaft 602 is driven to rotate by the driving motor 601, thereby driving the stirring rod 603 and the permanent magnet 604 to rotate, so as to mix the raw materials inside the mixing box 4. Because the permanent magnet 604 is hinged to the end face of the stirring rod 603, the stirring rod 603 will hit the triangular block 605 during the rotation, thereby causing the inside of the mixing box 4 to vibrate, thereby loosening the material attached to the box wall and the stirring rod, thereby reducing the accumulation and adhesion of the material.

[0051] The seal 701 includes a sealing block 7011 located inside the mixing box 4, a connecting block 7012 fixedly connected to the bottom of the sealing block 7011, and a guide block 7013 fixedly connected to the bottom of the connecting block 7012, wherein the sealing block 7011 is in the shape of a semi-cylinder, and the diameter of the sealing block 7011 is greater than the width of the discharge port 401, and the guide block 7013 is in the shape of a quadrangular pyramid and is made of ferromagnetic material, which facilitates the transportation of the fertilizer discharged from the discharge port 401 to the storage barrel 2.

[0052] The partition mechanism also includes a protrusion 702 fixedly connected to the bottom of the guide block 7013, a limiting rod 703 fixedly connected to the top of the guide block 7013, and a limiting hole opened at the bottom of the mixing box 4, and the limiting rod 703 slides inside the limiting hole, wherein the guide block 7013 is shaped like a semi-cylinder, and when the push rod 509 rotates, it will push the guide block 7013 to move.

[0053] The partition mechanism also includes an installation groove opened on the inner wall of the limiting hole, an electric push rod 704 fixedly connected to the inner wall of the installation groove, a locking hole opened on the outer wall of the limiting rod 703, and an electromagnet 705 embedded in the bottom plate of the mixing box 4. By starting the electric push rod 704, its end face is inserted into the locking hole, so that the seal 701 is fixed.

[0054] The raw materials of each component are conveyed into the mixing box 4, and then the driving motor 601 is started to drive the stirring rod 603 to rotate. At this time, the electric push rod 704 fixes the limit rod 703, and the discharge port 401 is in a sealed state. The raw materials are mixed by the stirring rod 603. When the stirring rod 603 rotates, it will hit the triangular block 605 to make the inside of the mixing box 4 vibrate, so as to loosen the materials attached to the box wall and the stirring rod 603, thereby reducing the accumulation and adhesion of the materials.

[0055] When the fertilizers are mixed, the electric push rod 704 is started to separate it from the limit rod 703, and then the electromagnet 705 is energized. At this time, the electromagnet 705 will have magnetic force, thereby adsorbing the guide block 7013, and then driving the guide block 7013 to move upward, thereby driving the connecting block 7012 and the sealing block 7011 to move upward, thereby opening the discharge port 401. At this time, the fertilizer inside the mixing box 4 will be transported to the storage barrel 2.

[0056] When mixing is completed, the electromagnet 705 and the drive motor 601 are turned off. At this time, the permanent magnet 604 will be adsorbed on the outer surface of the triangular block 605, thereby preventing the stirring rod 603 from being vertically located directly above the seal 701, thereby avoiding interference of the stirring rod 603 with the seal 701.

[0057] Example 2: Please refer to Figure 1-Figure 8 As shown, the present invention is a magnesium fertilizer application device for promoting carbon fixation and emission reduction in tea garden soil, comprising:

[0058] A trolley 1, a material storage barrel 2 is arranged on the top of the trolley 1, a material discharge mechanism is fixedly connected to the bottom of the material storage barrel 2, and a mixing box 4 is fixedly connected to the top of the material storage barrel 2;

[0059] The discharging mechanism includes a discharging pipe 301 fixedly connected to the bottom of the storage barrel 2, an air pump 302 fixedly connected to the bottom of the trolley 1, an electric telescopic rod 303 fixedly connected to the outer wall of the discharging pipe 301, and a discharge pipe 304 fixedly connected to the output end of the electric telescopic rod 303, wherein the air pump 302 is connected to the inside of the discharging pipe 301 through a hose, the discharge pipe 304 is sleeved on the outer surface of the discharging pipe 301, and the opening of the discharge pipe 304 is opened on the lower side wall, and the inner diameter of the discharge pipe 304 is equal to the outer diameter of the discharging pipe 301;

[0060] The dispersing mechanism includes a driving shaft 504 that penetrates the side wall of the storage barrel 2 and is rotatably connected to the side wall, and a transmission rod 505 that is fixedly connected to the outer side wall of the driving shaft 504 and is used to drive the driving shaft 504 to rotate;

[0061] The stirring mechanism includes a permanent magnet 604 movably disposed inside the mixing box 4, and a triangular block 605 fixedly connected to the inner wall of the mixing box 4;

[0062] The separation mechanism includes a discharge port 401 opened on the bottom plate of the mixing box 4 and a sealing member 701 penetrating the discharge port 401 for sealing the discharge port 401 .

[0063] The dispersing mechanism also includes a fixed sleeve 501 fixedly connected to the top of the trolley 1, and a slide bar 502 and a connecting spring 503 fixedly connected to the bottom of the storage barrel 2. The bottom end of the slide bar 502 slides inside the fixed sleeve 501, and the outer diameter of the slide bar 502 is equal to the inner diameter of the fixed sleeve 501. There are three groups of overall structures composed of the fixed sleeve 501 and the slide bar 502, which are linearly and evenly spaced. Through the cooperation of the fixed sleeve 501 and the slide bar 502, the storage barrel 2 can only perform a circular motion in the vertical direction. The bottom end of the connecting spring 503 is fixedly connected to the top of the trolley 1. There are four groups of connecting springs 503, which are distributed in a circular array.

[0064] The dispersing mechanism further includes a convex groove formed on the outer side wall of the transmission rod 505, a slider 506 movably disposed inside the convex groove, and a connecting rod 507 hinged to the outer side wall of the slider 506;

[0065] The trolley 1 is fixedly connected to the connecting rod 507 via a bracket, and the sliding block 506 slides inside the convex groove, thereby driving the transmission rod 505 to move, and further driving the driving shaft 504 to rotate.

[0066] There are two groups of integral structures consisting of the transmission rod 505, the convex groove, the slider 506, and the connecting rod 507. The two groups of integral structures are symmetrically arranged about the central axis of the drive shaft 504. By setting up the two groups of integral structures, the driving force on the drive shaft 504 is increased, thereby increasing the rotation angle of the drive shaft 504.

[0067] The breaking up mechanism also includes a breaking up rod 508 and a push rod 509 fixedly connected to the outer wall of the driving shaft 504. The breaking up rod 508 and the push rod 509 are both located inside the storage barrel 2. There are several breaking up rods 508, which are linearly and evenly distributed in the lower half of the driving shaft 504, and the push rod 509 is fixedly connected to the upper half of the driving shaft 504.

[0068] By starting the electric telescopic rod 303, it drives the opening of the feeding pipe 304 to face the fertilizer ditch, then opens the discharge port 401 and starts the air pump 302, and pushes the trolley 1 to move in the tea garden. At this time, the fertilizer will be transported to the fertilizer ditch through the feeding pipe 304. Because the road in the tea garden is uneven, the trolley 1 will vibrate during the movement. At this time, the fixed sleeve 501 cooperates with the sliding rod 502 and the connecting spring 503, so that the storage barrel 2 performs a vertical circular motion. At this time, the slider 506 will slide inside the convex groove. The driving shaft 504 is driven by the driving rod 504 to rotate, thereby driving the transmission rod 505 to move, and then driving the driving shaft 504 to rotate. When the driving shaft 504 is in the process of rotating, it will drive the breaking rod 508 and the push rod 509 to do pendulum motion, so that the breaking rod 508 breaks up the fertilizer, and the push rod 509 will push the guide block 7013 to move up and down during the rotation, so as to open the discharge port 401, so that the fertilizer inside the mixing box 4 can be continuously transported to the storage barrel 2, and the driving stability is improved by converting the vibration force into the driving force of the driving shaft 504.

[0072] S3, unloading and remixing: start the electric push rod 704 to separate it from the limit rod 703, then energize the electromagnet 705 to make it adsorb the guide block 7013, so that the fertilizer inside the mixing box 4 is transported to the storage barrel 2, and then repeat the operations of S1 and S2 to make the mixing box 4 full of mixed fertilizer;

[0073] S4, fertilization: open the discharge port 401 and the discharge mechanism, and push the trolley 1. When the trolley 1 vibrates, it will drive the storage barrel 2 to move up and down through the connecting spring 503, so that the two transmission rods 505 drive the slider 506 to slide inside the transmission rod 505, thereby driving the driving shaft 504 to rotate, thereby driving the breaking rod 508 and the push rod 509 to do pendulum motion.

[0074] First, different fertilizer trenches are dug according to the age of the tea trees in the tea garden. The standard of the fertilizer trench is as follows: for young tea trees, a fertilizer trench with a width of about 15 cm and a depth of 15 to 20 cm parallel to the tea row is dug 10 to 15 cm away from the root neck; for 3 to 4 year old tea trees, a trench is dug 35 to 40 cm away from the root neck; for mature tea gardens, a trench with a depth of 20 to 30 cm is dug vertically below the crown of the tree.
