TECHNICAL FIELD

[0001] The present application relates to the technical field of fertilizing device, in particular to a solid fertilizer directional fertilizing device for shallow root zone of crops. BACKGROUND

[0002] The crop refers to a plant that is cultivated and planted by human beings to obtain its fruits, seeds, stems, leaves, roots and other parts for edible, industrial raw materials, feed, medicinal purposes and the like.

[0003] The crop growth depends on the root system to absorb nutrients from the soil, and the root system of shallow root crops such as wheat seedlings and fruit tree seedlings is concentrated in the shallow soil layer of 10-15 cm below the ground. The traditional crop fertilization needs to be manually dug, manually fertilized and manually covered with tools. This fertilization method not only has high labor intensity, but also consumes time. However, in order to reduce the labor intensity and time consumption of the crop shallow root zone directional fertilization, the planting personnel will use the solid fertilizer directional fertilizing device for shallow root zone to assist the crop fertilization.

[0004] The existing fertilizing device can reduce the labor intensity and time consumption of the planting personnel, and improve the fertilization efficiency of the crops during actual use, but still has the following disadvantages: The core function of the fertilizing device is mainly concentrated in the ditching, fertilizing and soil covering links, and lacks the wetting ability of the soil at the fertilizing position. At this time, if the solid fertilizer is applied to the crops in the arid area, the solid fertilizer falling into the soil after ditching will be difficult to dissolve due to the lack of water in the soil, thereby affecting the growth of the crops due to the inability of the root system to absorb nutrients in time.

[0024] Example 1: Please refer to Figures 1-5 and Figures 8-12As shown, the present invention provides a technical solution: a directional fertilization device for solid fertilizer in the shallow root zone of crops, including a fertilization mechanism 1. The fertilization mechanism 1 is used to apply solid fertilizer to the soil in the shallow root zone around the crops. The fertilization mechanism 1 includes a mobile frame 101.

A placement frame 105 is fixed on the crossbar of the mobile frame 101, and a battery 10 is installed inside the placement frame 105. 6. A set of fixing brackets 107 are used to fix the battery 106 to the bottom of the inner wall of the placement frame 105. A controller 108 is installed at the top of the inclined frame of the mobile frame 101. A storage box 109 is installed on the inclined frame of the mobile frame 101. A perforated plate 110 is fixed to the outer wall of the storage box 109. A motor 111 is installed on the outer wall of the storage box 109. A round rod 124 is installed at the output end of the motor 111. The round rod 124 is rotatably connected to the inside of the round hole of the perforated plate 110. A set of connecting blocks 112 is fixed to the bottom of the perforated plate 110. A first perforated round plate 113 is fixed to the bottom of the round rod 124. A second perforated round plate is placed on the top of the first perforated round plate 113. 114, the bottom end of the round rod 124 movably passes through the top of the second perforated round plate 114, the bottom of each connecting block 112 is fixed to the top of the second perforated round plate 114, a guide pipe 116 is fixed on the crossbar of the mobile frame 101, a third perforated round plate 115 is fixed to the top of the guide pipe 116, the top of the third perforated round plate 115 contacts the bottom of the first perforated round plate 113, the inside of the through hole of the third perforated round plate 115 is connected to the inside of the guide pipe 116, the discharge end of the storage box 109 movably passes through the top of the second perforated round plate 114, the inside of the storage box 109 is connected to the inside of the through hole of the first perforated round plate 113, and the crossbar of the mobile frame 101 is fixed to the top of the guide pipe 116. A set of mounting blocks 125 is fixed, and a grooved column 117 is fixed between the mounting blocks 125. An arc-shaped block 118 is installed on the surface of the grooved column 117, and a trencher 119 is fixed at the bottom of the arc-shaped block 118. A soil cover 120 and a stabilizing bracket 121 are installed on the mobile frame 101. The soil cover 120 and the stabilizing bracket 121 are installed together by screws. A cover plate 122 is placed at the top opening of the storage box 109. A driver 123 is installed at the top of the inclined frame of the mobile frame 101. An auxiliary mechanism 2 is provided on the fertilization mechanism 1. The auxiliary mechanism 2 includes a water storage tank 201, a mounting hole 208 and an electric push rod 213. A water pump 202 is installed in the side groove of the water storage tank 201.

[0025] In this embodiment, when solid fertilizer needs to be applied to the soil for planting crops, the position of the ditch opener 119 is first adjusted using the grooved column 117 and the arc-shaped block 118, according to the required ditch depth. Simultaneously, the position of the soil cover 120 is also adjusted. When the traction equipment starts to move the fertilizer application device, the planting personnel need to hold the handle of the mobile frame 101 and move along with the fertilizer application device. The moving ditch opener 119 will then create a ditch where the fertilizer application device passes. Simultaneously, the moving soil cover 120, with the assistance of the stabilizing bracket 121, will push the soil pushed to both ends of the ditch by the ditch opener 119 back into the ditch. At the same time, the wheel axles of the mobile frame 101 will be connected to the two gears 103 and the mounting... With the cooperation of the frame 102, the detection end of the rotary encoder 104 rotates. The rotary encoder 104 then transmits the generated pulse signals to the controller 108. The controller 108 then uses its internal counting module to accumulate and record the number of pulses, and its internal revolutions calculation module to calculate the total number of revolutions (total revolutions + accumulated pulses ÷ pulses per revolution). The controller 108 then compares the calculated number of revolutions with a preset revolutions threshold. When the calculated number of revolutions is lower than the preset threshold, the controller 108 will not use the driver 123 to start the motor 111 and water pump 202, and will start the detection process again from the beginning. When the water pump 202 is turned off, the controller... Device 108, in conjunction with driver 123, starts motor 111. Motor 111, in cooperation with perforated plate 110 and round rod 124, drives the first perforated circular plate 113 to rotate. The solid fertilizer inside the through-hole of the rotating first perforated circular plate 113 moves stably with the cooperation of the second and third perforated circular plates 114 and 115. When the first perforated circular plate 113 rotates 180 degrees, the through-hole of the first perforated circular plate 113 is completely connected to the through-hole of the third perforated circular plate 115. At this point, the solid fertilizer inside the through-hole of the first perforated circular plate 113 first enters the through-hole of the third perforated circular plate 115, and then enters the guide tube 116. Simultaneously, motor 111... After the solid fertilizer inside the through hole 15 is completely released, the first perforated circular plate 113 is reset. After the first perforated circular plate 113 is reset to its original position, the motor 111 is paused using the driver 123, and solid fertilizer is filled in. It is then guided onto the soil that has just been moistened with water. The solid fertilizer that comes into contact with the water will quickly dissolve, forming liquid nutrients. At this point, the solid fertilizer, which has become liquid nutrients, can be better and more promptly absorbed by the crop roots. Afterward, the soil cover 120 moves over and pushes the soil that was pushed to the sides of the trench during the trenching process back into the trench, covering the trench where the solid fertilizer was applied. When the number of revolutions threshold calculated by the controller 108 is again the same as the number of revolutions threshold preset by the controller 108, the fertilization device will repeat the above operation again.First, moisten the soil, then apply fertilizer, then cover with soil. Repeat this process to perform equidistant fertilization.

[0026] Example 2: According to Figures 1-4 , Figure 6 , Figure 7 , Figure 9 , Figure 11 and Figure 12 As shown, the fertilization mechanism 1 is equipped with an auxiliary mechanism 2, which is used to dissolve solid fertilizer. The auxiliary mechanism 2 includes a water storage tank 201, a mounting hole 208, and an electric push rod 213. A water pump 202 is installed in the side groove of the water storage tank 201. The water inlet end near the bottom of the water storage tank 201 is connected to a flexible hose 203. The water inlet end of the flexible hose 203 is connected to a filter cover 204. A perforated bracket 205 is fixedly sleeved on the filter cover 204. A buoyancy ring 206 is glued to the top of the perforated bracket 205. The water inlet and outlet ends of the water pump 202 are both connected to water pipes 207, one of which is... The outlet of pipe 207 is connected to a round pipe 210, and the outlet of the round pipe 210 is connected to a nozzle 211. The inlet of another water pipe 207 is connected to the outlet of the side of the water storage tank 201 near the bottom. A hollow block 209 is fixedly fitted inside the mounting hole 208, and the round pipe 210 is fixedly fitted inside the hollow block 209. A perforated block 212 is fixedly fitted onto the outer surface of the electric push rod 213. A telescopic tube 214 is movably fitted onto the telescopic end of the electric push rod 213. A connecting plate 215 is installed on the telescopic end of the electric push rod 213. One end of the telescopic tube 214 is connected to the surface of the connecting plate 215. The telescopic tube 214 is mounted face-to-face with the other end of the electric push rod 213. A protective shell 216 is fixed to the side of the connecting plate 215 away from the electric push rod 213. The two limiting ends of the protective shell 216 are slidably connected to the two grooves on the surface of the hollow block 209. A protective pad 217 is adhered to the inner wall of the protective shell 216. The nozzle 211 is located inside the protective shell 216. The surface of the protective pad 217 is in contact with the water outlet surface of the nozzle 211. A lid 218 is placed at the top opening of the water storage tank 201. The fertilizer applicator 1 includes a mobile frame 101 and a water storage tank. Box 201 is installed on the crossbar of the mobile frame 101 near the edge. Controller 108 is installed at the top of the inclined frame of the mobile frame 101. A set of mounting blocks 125 is fixed on the crossbar of the mobile frame 101. A grooved post 117 is fixed between the mounting blocks 125. An arc-shaped block 118 is installed on the surface of the grooved post 117. A trencher 119 is fixed at the bottom of the arc-shaped block 118. Mounting holes 208 are pre-set on the trencher 119. A perforated block 212 is fixed on the inner surface of the trencher 119. Driver 123 is installed at the top of the inclined frame of the mobile frame 101.

[0027] In this embodiment, when the fertilizing device moves to the area where fertilization is needed, the controller 108 first activates the electric push rod 213. The activated electric push rod 213, in cooperation with the perforated block 212, drives the connecting plate 215 to move towards the perforated block 212. Simultaneously, the moving connecting plate 215, in cooperation with the fixed end of the electric push rod 213, causes the telescopic tube 214 to retract. The moving connecting plate 215 also drives the protective shell 216 to move, which in turn drives the protective pad 217 to move. When the protective shell 216 is completely removed from the nozzle 211, the controller 108 pauses the electric push rod 213. When the number of revolutions calculated by the controller 108 matches the number of revolutions preset by the controller 108, the controller 108 first uses the driver 12... 3. With the cooperation of the start of the water pump 202, the water pump 202 will also be retested. At this time, the water pump 202, with the cooperation of the water pipe 207, hose 203, filter cover 204, perforated bracket 205 and buoyancy ring 206 connected to its water inlet end, will first filter the clean water in the water storage tank 201 and then deliver it to the water pipe 207 connected to the water outlet end of the water pump 202. Then the water entering the water pipe 207 connected to the water outlet end of the water pump 202 will be delivered to the round pipe 210 and then to the nozzle 211. After that, it will be atomized and sprayed on the soil to moisten the soil. When the time for the water pump 202 to start is reached, the controller 108 will use the driver 123 to stop the water pump 202, that is, to realize the soil moistening operation before the solid fertilizer is applied to the required position in the trench after trenching.

[0028] The overall effect and working principle of the mechanism are as follows: During the preparation phase, first connect the rotary encoder 104, battery 106, controller 108, motor 111, driver 123, water pump 202, and electric actuator 213 according to electrical connection safety requirements and drawing requirements. Then, power the controller 108 with battery 106 to enter the initial interface. Next, set various parameters such as the number of pulses per revolution of the rotary encoder 104, the motor speed 111, the extension and retraction frequency of the electric actuator 213, the output speed of the water pump 202, and the start-up duration. At the same time, set the revolution threshold (set according to the actual situation). Next, move the entire fertilization device to the place where fertilization is needed, then remove the cover plate 122, inject an appropriate amount of solid fertilizer into the storage tank 109, and after completing the operation, install the cover plate 122 back in its original position. Then remove the tank cover 218, inject an appropriate amount of clean water into the water storage tank 201, and after completing the operation, install the tank cover 218 back in its original position. At this time, with the cooperation of the buoyancy ring 206 and the perforated frame 205, the filter cover 204 is close to the water surface inside the water storage tank 201. Finally, connect the mobile frame 101 to the traction equipment. Before wetting the soil, when the fertilizing device is moved to the area where fertilization is needed, the controller 108 first activates the electric push rod 213. The activated electric push rod 213, in cooperation with the perforated block 212, drives the connecting plate 215 to move towards the perforated block 212. At the same time, the moving connecting plate 215, in cooperation with the fixed end of the electric push rod 213, causes the telescopic tube 214 to retract. Simultaneously, the moving connecting plate 215 drives the protective shell 216 (when no positional movement occurs, the protective shell 216 can protect the nozzle 211 to prevent the nozzle 211 from being sprayed onto hard objects on the road surface and damaged when the fertilizing device moves) to move. The moving protective shell 216 drives the protective pad 217 to move. When the protective shell 216 is completely removed from the nozzle 211, the controller 108 will pause the electric push rod 213. Before fertilization, when applying solid fertilizer to the soil for planting crops, the trenching depth is determined by using the grooved column 117 and the arc-shaped block 118 to adjust the position of the trencher 119 (for directional trenching, i.e., shallow root zone). Simultaneously, the position of the cover 120 is adjusted. When the traction equipment begins to move the fertilization device, the planter must hold the handle of the mobile frame 101 and move with the fertilization device. The moving trencher 119 will then create a trench where the fertilization device passes. Simultaneously, the moving cover 120, with the assistance of the stabilizing bracket 121, will push back the soil pushed to both ends of the trench during trenching by the trencher 119 into the trench. At the same time, the moving mobile frame 101... The axle, in cooperation with the two gears 103 and the mounting bracket 102, drives the detection end of the rotary encoder 104 to rotate. Then, the rotary encoder 104 transmits the generated pulse signal to the controller 108. The controller 108 then uses its internal counting module to accumulate and record the number of pulses, and uses its internal revolution calculation module to calculate the total number of revolutions (total number of revolutions + accumulated number of pulses ÷ number of pulses per revolution). The controller 108 then compares the calculated number of revolutions with the revolution threshold set in advance. When the number of revolutions calculated by the controller 108 is lower than the revolution threshold set in advance, the controller 108 will not use the driver 123 to start the motor 111 and the water pump 202, and will start the detection again from the beginning. After the soil is moistened, when the number of revolutions calculated by the controller 108 is the same as the number of revolutions preset by the controller 108, the controller 108 will first start the water pump 202 with the help of the driver 123. At the same time, it will also start the test again. The water pump 202, with the cooperation of the water pipe 207, hose 203, filter cover 204, perforated bracket 205 and buoyancy ring 206 connected to its water inlet end, first filters the clean water in the water tank 201, and then delivers it to the water pipe 207 connected to the water outlet end of the water pump 202. Then the water entering the water pipe 207 connected to the water outlet end of the water pump 202 will be delivered to the inside of the round pipe 210, and then to the inside of the nozzle 211, and then atomized and sprayed on the soil to moisten the soil. When the time for the water pump 202 to start is reached, the controller 108 will stop the water pump 202 with the help of the driver 123. In the post-fertilization stage, when the water pump 202 is turned off, the controller 108, in conjunction with the driver 123, starts the motor 111. The started motor 111, in conjunction with the perforated plate 110 and the round rod 124, drives the first perforated circular plate 113 to rotate (when solid fertilizer is injected into the storage tank 109, some solid fertilizer is first released from the discharge end at the bottom of the storage tank 109 and enters the through-hole on the first perforated circular plate 113). The solid fertilizer inside the through-hole of the rotating first perforated circular plate 113 then moves stably in conjunction with the second perforated circular plate 114 and the third perforated circular plate 115. When the first perforated circular plate 113 rotates 180 degrees, the through-hole on the first perforated circular plate 113 is completely connected to the through-hole on the third perforated circular plate 115. At this point, the solid fertilizer inside the through-hole of the first perforated circular plate 113 first enters the through-hole of the third perforated circular plate 115, and then enters the guide... Inside the feed pipe 116, after the solid fertilizer inside the through hole in the third perforated circular plate 115 is completely released, the first perforated circular plate 113 is reset again. After the first perforated circular plate 113 is reset to its original position, the motor 111 is paused with the help of the driver 123, and solid fertilizer is filled in. Then it is guided onto the soil that has just been moistened with water. The solid fertilizer that comes into contact with water will quickly dissolve and form liquid nutrients. At this time, the solid fertilizer that has become liquid nutrients can be better and more timely absorbed by the crop roots. Then the soil coverer 120 that moves over will push the soil that was pushed to both sides of the trench during the trenching process back into the trench to cover the trench into which solid fertilizer was applied. When the number of cycles calculated by the controller 108 is the same as the number of cycles preset by the controller 108, the fertilization device will repeat the above operation again, first moistening the soil, then applying fertilizer, then covering the soil, and so on, so as to perform equidistant fertilization operation.
