[0002] Fertilizer applicator is a machine for applying fertilizer. It consists of a fertilizer box, a fertilizer dispenser, etc. Some of them also have fertilizer conveying, ditching, and covering devices. According to the properties of the fertilizer applied, it can be divided into solid fertilizer applicators, liquid fertilizer applicators, manure spreaders, and liquid fertilizer applicators; according to the different growth stages of crops, it can be divided into base fertilizer applicators, seed fertilizer applicators, and topdressing fertilizer applicators; according to the operation method, it can be divided into strip applicators, spreaders, deep applicators, and foliar fertilizer applicators.

[0003] Chinese patent CN111837547A discloses a soil fertilization device and method for planting bamboo shoots. A stirring assembly is arranged in a fertilizer tank to break up the fertilizer, and a sliding rod and a sliding sleeve on both sides of the fertilizer tank can drive the fertilizer tank to vibrate slightly up and down, so that the fertilizer in the fertilizer tank is evenly sprinkled through the discharge port and then through the fertilization port, so that the bamboo shoots can get an appropriate amount of fertilizer and grow well.

[0004] When the above-mentioned fertilizing equipment is in use, the fertilizer will be sprinkled onto the soil surface around the bamboo shoots by pushing the equipment above the bamboo shoots. The nutrients provided by the fertilizer are difficult to penetrate into the lower soil layer. As the bamboo shoots grow over time, they need to be topdressed regularly and quantitatively. In addition, fallen leaves or weeds are easily accumulated on the surrounding soil surface, so that part of the fertilizer is intercepted and cannot contact the soil, resulting in difficulty for the roots of the bamboo shoots to absorb the nutrients of the fertilizer in the soil.

[0020] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] 1. By driving the conveyor belt to slide along the arc track on both sides of the annular base, the shovel tools on both sides are driven to move along the limiting chute to dig up the soil around the bamboo shoots for fertilization. Digging up the soil can increase the permeability of the soil, help enhance the bamboo shoots' ability to absorb water and nutrients, promote the healthy growth of the bamboo shoots' roots, and make the bamboo shoots located at the center of the circle of the annular base, so as to avoid fertilizing too close to the roots of the bamboo shoots, which may cause the bamboo shoots to burn their roots. The shovel tools can also destroy the surrounding weeds in the process of loosening the soil, which helps to reduce the growth of weeds and reduce the competition for nutrients and water for the bamboo shoots. When the shovel tools move along the limiting chute, they will push the sealing component in the feeding port to open, and each feeding box in the annular base will be fed and fertilized in turn. As the shovel tools move along the limiting chute, the fertilizer is evenly scattered in the dug groove, ensuring that the bamboo shoots can evenly absorb the required nutrients, which can more effectively improve the growth quality of the bamboo shoots than simply fertilizing on the surface.

[0022] 2. When the earth-shoveling tool pushes the sliding gate block to move, the intercepting gate plate connected to one side of the sliding gate block will be driven to be stored in the placement groove, so that the feeding port through which the earth-shoveling tool passes is opened for feeding and fertilization, so that the fertilizer can penetrate into the soil more evenly, and the root system of bamboo shoots can absorb nutrients more effectively, thereby promoting the rapid growth of bamboo shoots. When the earth-shoveling tool passes through the sliding gate block, the compressed reset spring piece pushes the sliding gate block to slide and reset along the storage chute under the reaction force, which can effectively reduce the overflow of fertilizer into the surrounding environment, and can more accurately control the flow of fertilizer, avoiding the interruption of bamboo shoot growth due to too much or too little fertilizer.

[0023] 3. The buffer spring will push the bottom end of the feed box to contact and collide with the upper end of the feed port, so that the fertilizer in the feed box will be shaken off the filter plate. At the same time, the coordinated gears on both sides of the top of the feed box will rotate along the meshing matching racks, driving the flip covers on both sides of the top of the feed box to open. The fertilizer stored in the loading box will be replenished to the lower feed box again through the hose, ensuring that there is enough fertilizer supply in the feed box during fertilization, which can effectively improve the efficiency and accuracy of fertilization, provide more balanced and continuous nutritional support for bamboo shoots, and promote their healthy growth.

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.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Example 1

[0040] Reference Figure 1-Figure 5 , Fig. 9, which is the first embodiment of the present invention, provides a fertilizer application device, including a control main rod 100, a ring-shaped shoveling mechanism 200 is installed at the bottom end of the control main rod 100, and the ring-shaped shoveling mechanism 200 includes a ring-shaped base 201 fixedly connected to the bottom end of the control main rod 100, and a ring-shaped upper shell 202 is fixedly connected to the upper surface of the ring-shaped base 201. The ring-shaped base 201 and the ring-shaped upper shell 202 are both C-shaped, and bamboo shoots enter and exit the ring-shaped base 201 from the C-shaped opening. Both sides of the inner part of the ring-shaped base 201 are provided A conveyor belt 208 is arranged, and the two sets of conveyor belts 208 are symmetrically arc-shaped and run in opposite directions. A lifting assembly is arranged on the lower surface of the conveyor belt 208, and a shovel cutter 210 is connected below the lifting assembly. A limited position slide groove 211 is arranged on the lower surface of the annular base 201. The lifting assembly can adjust the distance between the shovel cutter 210 and the annular base 201. The operation of the conveyor belt 208 drives the shovel cutter 210 to move along the limited position slide groove 211, and moves in a circle along the bamboo shoots to dig the surrounding soil;

[0041] There are several uniform material spreading mechanisms 300 evenly distributed on the annular base 201, and the uniform material spreading mechanism 300 includes a material box 304 and a material port 301 opened on the lower surface of the annular base 201, and a sealing component capable of pushing the material box 304 to shake the material is arranged in the material port 301, and an opening and closing component capable of controlling the opening and closing state of the material feed port of the material box 304 is arranged on the material box 304, and the conveyor belt 208 can trigger the sealing components one by one in the process of driving the earth-moving tool 210 to move along the limiting slide groove 211, and after the earth-moving tool 210 digs the soil around the bamboo shoots, it drives each sealing component passing by to move so that the corresponding material box 304 shakes downward for fertilization, and when the material box 304 moves downward, it can drive the opening and closing component to open the material feed port of the material box 304 to load new fertilizer.

[0042] Specifically, the bamboo shoots enter the annular base 201 and the annular upper shell 202 through the opening, so that the bamboo shoots are located at the center of the annular base 201 and the annular upper shell 202, so as to avoid fertilizing too close to the roots of the bamboo shoots, which may cause root burns of the bamboo shoots. The conveyor belt 208 drives the lifting assembly below to slide in the limiting slide groove 211, so that the shoveling tools 210 on both sides move along the limiting slide groove 211 to dig the soil around the bamboo shoots. While the shoveling tools 210 move along the limiting slide groove 211 to dig the soil, the sealing components under the annular base 201 will be pushed open in turn, so that the shoveling tools 210 pass through the rear discharge port 301 for fertilization, and the discharge box 304 falls and collides with the upper end of the discharge port 301, so that the fertilizer is evenly distributed in the soil dug by the shoveling tools 210 around the bamboo shoots.

[0043] By driving the conveyor belt 208 to slide along the arc track on both sides of the annular base 201, the shovel cutters 210 on both sides are driven to move along the limiting slide groove 211 to dig up the soil around the bamboo shoots for fertilization. Digging up the soil can increase the permeability of the soil, which helps to enhance the bamboo shoots' ability to absorb water and nutrients, promote the healthy growth of the bamboo shoots' roots, and make the bamboo shoots located at the center of the annular base 201, avoiding fertilization too close to the roots of the bamboo shoots, which may cause the bamboo shoots to burn their roots. The shovel cutters 210 can also be used in the process of loosening the soil. In order to destroy the surrounding weeds, it helps to reduce the growth of weeds and reduce the competition for nutrients and water for bamboo shoots. When the earth-shoveling tool 210 moves along the limiting slide groove 211, it will push the sealing component in the feed port 301 to open, and each feed box 304 in the annular base 201 will discharge and fertilize in turn. As the earth-shoveling tool 210 moves along the limiting slide groove 211, the fertilizer is evenly scattered in the dug groove, ensuring that the bamboo shoots can evenly absorb the required nutrients, which can more effectively improve the growth quality of bamboo shoots than simply fertilizing the surface.

[0046] Specifically, when the conveyor belt 208 is running in the forward direction, it drives the corresponding earth-shoveling tool 210 to move forward along the limiting chute 211 and gradually approach the C-shaped opening. The conveyor belt 208 drives the fixed sleeve 212 to slide in the limiting chute 211, drives the limiting slider 215 on the earth-shoveling tool 210 to move and pushes the sealing component on one side through its vertical surface to open for fertilization; when the conveyor belt 208 is running in the reverse direction, the conveyor belt 208 drives the earth-shoveling tool 210 under the annular base 201 to move and reset along the limiting chute 211. When the reverse movement contacts the sealing component, the limiting slider 215 The rounded edge 216 on one side will pass along the rounded corner on the sealing assembly, so that the limiting slider 215 drives the earth-moving tool 210 to descend and pull the upper lifting slider 213 to slide. The lifting slider 213 extends downward from the fixed sleeve 212 to pull the lifting spring piece 214, so that the sealing assembly slides along the upper surface of the limiting slider 215. When the limiting slider 215 passes through the sealing assembly, the lifting spring piece 214 will retract the lifting slider 213 into the fixed sleeve 212 under the reaction force.

While the feed box 304 moves downward, the coordinated gears 321 on both sides of the top of the feed box 304 will rotate along the meshing matching racks 322, driving the flip covers 320 on both sides of the top of the feed box 304 to open, and the fertilizer stored in the charging box 323 will be replenished in the feed box 304 again through the hose;

[0056] After the movable column 311 moves to the inclined groove of the horizontal slide groove 312, as the earthmoving tool 210 continues to move along the limiting slide groove 211, the limiting slider 215 will push the sliding block 309 to move obliquely upward until the movable column 311 moves to the upper horizontal groove of the horizontal slide groove 312. At this time, the rounded corner at the bottom of the sliding block 309 rises and moves to the upper surface of the limiting slider 215 (a small rounded corner is provided at the junction of the vertical surface of the limiting slider 215 and the upper surface, and the small rounded corner at the bottom of the sliding block 309 Under the action of the rounded corners and the small rounded corners, the sliding gate block 309 moving obliquely upward can move from one side of the limiting slider 215 to the upper surface of the limiting slider 215). When the upper surface of the limiting slider 215 passes along the bottom end of the sliding gate block 309, the compressed reset spring 316 pushes the sliding gate block 309 to slide and reset along the receiving slide groove 308 under the sliding cooperation of the movable column 311 and the horizontal slide groove 312 under the reaction, and the sealing component closes the outlet of the discharge port 301.

[0057] When fertilization is completed, the annular base 201 is removed from the bamboo shoots, and the corresponding earth-shoveling tool 210 is driven by the conveyor belt 208 to move in the opposite direction and reset. When the earth-shoveling tool 210 moves in the opposite direction along the limiting slide groove 211 to reset, since the sliding gate block 309 is attached to the inner wall of the discharge port 301, the sliding gate block 309 cannot be displaced along the moving direction of the limiting slider 215. The rounded edge 216 on the side of the limiting slider 215 will contact the rounded corner at the bottom of the sliding gate block 309. As the earth-shoveling tool 210 continues to move, the limiting slider 215 will pull the lifting slider 213 to slide downward from the fixed sleeve 212, so that the sliding gate block 309 passes along the upper surface of the limiting slider 215.
