[0001] The present invention relates to the technical field of agricultural machinery, in particular to a fertilizing device for tea planting with a quantitative feeding mechanism. Background Art

[0002] In modern agricultural machinery, planting and fertilizing vehicles are core equipment often used in planting crops. With the development of agriculture and the popularization of mechanical equipment, the working environment of planting and fertilizing vehicles has become increasingly complex. The planting and fertilizing vehicles in the existing technology have many defects. They cannot fertilize and irrigate at the same time during work. At the same time, the quantitative adjustment of each fertilizer application is different, and the next operation often requires manual readjustment, which is time-consuming and labor-intensive.

[0003] Therefore, in response to the above-mentioned shortcomings, the present invention provides a tea planting fertilizer application equipment with a quantitative delivery mechanism, which can adjust the fertilization quantity through the fertilization mechanism to meet the fertilization needs of different planting stages. The irrigation mechanism can control the single irrigation water volume to achieve quantitative irrigation, thereby meeting the urgent needs of agricultural development for planting and fertilizing vehicles.

[0010] Preferably, the water injection assembly includes a water outlet bucket, the inner wall of the water outlet bucket is fixedly connected to the limiting bucket, the inner wall of the limiting bucket is slidably connected to a water injection piston, the inner wall of the limiting bucket close to the water tank is slidably connected to the limiting water inlet plate, the outer wall of the limiting water inlet plate is fixedly connected to an extrusion connecting ring, the inner wall of the water injection piston is threadedly connected to a pressing screw, the outer wall of the pressing screw away from the limiting water inlet plate is fixedly connected to the outer wall of the extrusion connecting ring, the outer wall of the water injection piston is slidably connected to the inner wall of the limiting bucket, when it is necessary to adjust the irrigation quantity, the water outlet hole position of the limiting bucket can be changed, and the water output of each irrigation can be changed by changing the number of water outlet holes of the limiting bucket. When it is necessary to increase the irrigation water volume, the water injection piston 322 is rotated to move the water injection piston downward, increase the water outlet holes of the limiting bucket, so that the water flow rate per unit time becomes larger, and the irrigation quantity can be adjusted.

[0011] Preferably, the inner wall of the end of the pressing screw away from the limiting water inlet plate is fixedly connected to a connecting rod, the end of the connecting rod close to the vehicle body is fixedly connected to a four-arm connecting rod, and the end of the four-arm connecting rod away from the connecting rod is rotatably connected to the outer wall of the driving wheel. The water injection assembly of the irrigation mechanism drives the water injection piston to move up and down in the limiting barrel through the linkage of the four-arm connecting rod, the connecting rod and the pressing screw. The water injection assembly of the irrigation mechanism drives the water injection piston to move up and down in the limiting barrel through the linkage of the four-arm connecting rod, the connecting rod and the pressing screw. By rotating the water injection piston to adjust the number of water outlet holes in the limiting barrel, the single irrigation water volume can be controlled to achieve quantitative irrigation.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. This invention achieves quantitative fertilizer intake and delivery by configuring the reciprocating motion of a piston in the feed assembly, in conjunction with a return spring, a limit spring, and a push rod. When the piston moves backward, a negative pressure is created in the feed barrel, sucking fertilizer from the storage tank. When the negative pressure piston moves forward, airflow pushes the fertilizer through the feed pipe and into the mixing assembly. By varying the operating power of the air pump, adjusting the piston's stroke and reciprocating frequency, the feed barrel's single fertilizer intake and delivery rate can be adjusted to meet fertilization needs at different planting stages and prevent fertilizer waste or shortages.

[0015] 2. This invention incorporates an irrigation mechanism. Its water injection assembly, linked by a four-arm connecting rod, a connecting rod, and a pressure screw, drives an injection piston up and down within a stopper barrel. Rotating the injection piston adjusts the number of water outlet holes in the stopper barrel, controlling the amount of water delivered per irrigation session and achieving quantitative irrigation. A motor-driven fertilization mechanism works in tandem with the irrigation mechanism, simultaneously fertilizing and irrigating. This reduces repetitive operations and improves tea garden management efficiency.

[0016] 3. This invention utilizes equidistant expansion rods, whose spacing is adjusted by a telescopic cylinder, to drive the lateral movement of the agitator assembly and discharge guide plate, achieving adaptive adjustment of the spacing between fertilization and irrigation. Shortening the expansion rods increases the spacing, while extending them decreases it, making it suitable for tea plantations with varying row spacings. The lifting legs, combined with the support base, support arms, and lifting wires, adjust the overall height of the device to accommodate tea plantations with varying terrains, enhancing the device's terrain adaptability.

[0017] 4. This invention incorporates a stirring assembly. A rotating shaft in the stirring assembly drives the T-bar, rotating rod, and disturbance plate to rotate. The stirring blades cooperate with the scraper rod to stir and break up the fertilizer, preventing fertilizer from clumping and clogging within the mixing barrel. If fertilizer in the storage bin becomes compacted after long-term storage, the motor drives the feed wheel shaft to rotate. This, in turn, drives the drive wheel through the drive wheel and transmission belt, pre-breaking the compacted fertilizer. This ensures smooth material intake by the feed assembly and reduces manual intervention. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Working principle:

[0048] When in use, through the coordinated action of the fertilizing mechanism 2, the irrigation mechanism 3, and the lifting mechanism 4, the quantitative feeding of fertilizers and the quantitative irrigation of crops are achieved through the feeding component 27, the stirring component 28, and the water injection component 33.

[0049] When the tea plants are high and the height of the vehicle body 1 needs to be raised, the lifting screw rod 41 is rotated, and the connecting block 43 moves toward each other under the action of the lifting screw rod 41, driving the support arm 42 to rotate, so that the distance between the support seats 40 becomes larger, driving the lifting legs 12 and the support legs 13 fixedly connected to the support seats 40 to unfold, thereby increasing the height of the vehicle body 1. When the height of the vehicle body 1 needs to be lowered, the lifting screw rod 41 is rotated, and the connecting block 43 moves backward under the action of the lifting screw rod 41, driving the support arm 42 to rotate, so that the distance between the support seats 40 becomes smaller, driving the lifting legs 12 and the support legs 13 fixedly connected to the support seats 40 to contract, thereby lowering the height of the vehicle body 1.

[0050] When the lateral spacing between fertilization and irrigation needs to be adjusted, the lateral spacing between fertilization and irrigation is adjusted by adjusting the length of the telescopic rod of the telescopic cylinder 15. When the spacing needs to be increased, the length of the telescopic rod of the telescopic cylinder 15 is shortened, and the equidistant expansion rods 29 are expanded to increase the spacing between the stirring assembly 28 and the discharge guide plate 25, thereby adjusting the lateral spacing between fertilization and irrigation. When the spacing needs to be reduced, the length of the telescopic rod of the telescopic cylinder 15 is increased, and the equidistant expansion rods 29 are contracted to increase the spacing between the stirring assembly 28 and the discharge guide plate 25, thereby adjusting the lateral spacing between fertilization and irrigation.

[0051] When it is necessary to adjust the quantitative amount of fertilizer application, the stroke of the negative pressure piston 271 of the feeding assembly 27 is variable, and the single fertilizer absorption amount is determined by changing the volume of the feeding barrel 275. When it is necessary to increase the amount of fertilizer application, the working power of the air pump 10 is increased, so that the stroke of the negative pressure piston 271 becomes larger, the reciprocating frequency is accelerated, the single fertilizer absorption amount and the fertilizer discharge speed are increased, and the quantitative amount of fertilizer application is adjusted. When it is necessary to reduce the amount of fertilizer application, the working power of the air pump 10 is reduced, so that the stroke of the negative pressure piston 271 becomes smaller, the reciprocating frequency is slowed down, the single fertilizer absorption amount and the fertilizer discharge speed are reduced, and the quantitative amount of fertilizer application is adjusted.

[0052] When the irrigation quantity needs to be adjusted, the water outlet hole position of the limit barrel 333 can be changed. By changing the number of water outlet holes of the limit barrel 333, the water outlet of each irrigation can be changed. When the irrigation water volume needs to be increased, the water injection piston 322 is rotated to move the water injection piston 322 downward, and the water outlet holes of the limit barrel 333 are increased, so that the water flow rate per unit time becomes larger, and the irrigation quantity is adjusted. When the irrigation water volume needs to be reduced, the water injection piston 322 is rotated to move the water injection piston 322 upward, and the water outlet hole position of the limit barrel 333 is reduced, so that the water flow rate per unit time becomes smaller, and the irrigation quantity is adjusted.

[0053] When fertilizer clumps and becomes clogged during fertilization, or when fertilizer is stored in the storage box 20 for a long time and becomes hardened and cannot enter the feed assembly 27, the motor 11 is started, and the motor 11 drives the feed wheel shaft 212 to rotate, so that the hardened fertilizer breaks up and enters the feed assembly 27. When the fertilizer in the feed assembly 27 is pushed into the stirring assembly 28 by the negative pressure piston 271, and some large particles are squeezed out, the motor 11 drives the transmission wheel 23 through the driving wheel 21 and the transmission belt 22, so that the rotating shaft 24 rotates, so that the T-bar (280) drives the rotating rod 281 to open, so that the large particles of fertilizer are evenly dispersed under the action of the disturbance plate 282, the stirring blade 283 and the scraper rod 284.

[0054] During fertilization, after the motor 11 is started, the driving wheel 21 is driven to rotate through the feed wheel shaft 212, and the power is transmitted to the transmission wheel 23 through the transmission belt 22, so that the rotating shaft 24 rotates, driving the stirring assembly 28 and the feeding assembly 27 to work together. During fertilization, the air pump 10 works, and the gas passes through the feed air pipe 26 to make the negative pressure piston 271 of the feeding assembly 27 reciprocate in the negative pressure conduit 270. When the negative pressure piston 271 moves backward, negative pressure is formed in the feeding barrel 275, and the feeding piston 2710 overcomes the fixed connection to the feeding conduit 2712. The retaining spring 2711 on the upper part of the hopper 20 opens, and the fertilizer in the storage box 20 enters the feed barrel 275 through the metal feed pipe 210. When the negative pressure piston 271 moves forward, the feed piston 2710 closes, and the vent piston 279 opens, overcoming the resistance of the limit spring 278 fixed to the limit plate 277. Under the action of the push rod 274, the air blocking plate 273 overcomes the resistance of the return spring 276 and slides open along the inner wall of the vent pipe 272. Driven by the negative pressure piston 271 and the air flow, the fertilizer enters the mixing barrel 285 through the feed pipe 211. The T-bar 280 on the rotating shaft 24 drives the rotating rod 281 and the disturbance plate 282 to rotate, and the stirring blades 283 stir the fertilizer to ensure uniform delivery. The stirred fertilizer slides through the discharge guide plate 25, ensuring uniform delivery as the wheels 14 advance.

[0055] During irrigation, when the driving wheel 21 rotates, the connecting rod 32 is driven to reciprocate through the four-arm connecting rod 31, so that the pressing screw rod 330 pushes the water injection piston 322 to move up and down in the limit barrel 333. When the pressing screw rod 330 moves downward, the limit water inlet plate 334 opens, and the water in the water tank 30 enters the water outlet barrel 335 through the limit barrel 333. The water is sprayed out through the connecting pipe 34, the fixing plate 35 and the water outlet pipe 36 to achieve irrigation. When the pressing screw rod 330 moves upward, the squeezing connecting ring 331 moves upward, the limit water inlet plate 334 moves upward, the water inlet is closed, and the water is sprayed out through the connecting pipe 34, the fixing plate 35 and the water outlet pipe 36 to achieve irrigation.
