[0001] The present application relates to the technical field of sorghum planting, in particular to a precise fertilization system for brewing sorghum and a fertilization method thereof. BACKGROUND

[0002] Sorghum is an annual herbaceous plant, which is widely cultivated in China, especially in the northeast. Sorghum grains can be used for food and wine making. Sorghum has a wide adaptability to soil and strong fertilizer absorption. It is easier to achieve high yield in sandy loam with rich organic matter and high fertility. In the lean and dry land, phosphorus and potassium are low, and fertilizer must be applied to get a good harvest.

In addition, it can prevent seedlings from being burned by contact with excessively high concentrations of fertilizer, further ensuring the healthy growth of seedlings. The coordinated operation of the soil-breaking blades and baffles can accurately create trenches, and with the assistance of the burying plate, the fertilizer can be effectively buried in the soil, ensuring that the fertilizer is fully mixed with the soil, promoting the uniform release of nutrients, and further improving soil fertility and crop growth.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of the present invention will now be described.

[0019] A precision fertilization system and method for brewing sorghum, such as Figures 1 to 9 As shown, the device includes a fertilizer hopper assembly 100 and a support frame 200. The support frame 200 is mounted on the bottom of the fertilizer hopper assembly 100 and can move to fertilize the sorghum. The fertilization device consists of the fertilizer hopper assembly 100 and the support frame 200. The fertilizer hopper assembly 100 includes a hopper 110 for temporarily storing fertilizer. A feed roller 150 is rotatably provided inside the hopper 110 along its length. Two sets of crushing grids 130 are rotatably connected in an inclined manner inside the hopper 110. The two sets of crushing grids 130 can be pulled by the feed roller 150 to be relatively close to the crushed fertilizer. The support frame 200 includes a support frame mounted on the bottom outer wall of the fertilizer hopper assembly 100. Multiple sets of fertilizer application components 250 are mounted inside the support frame along its length. Each set of fertilizer application components 250 is fixed to the support frame with bolts. Each set of fertilizer application components 250 includes two sets of baffles 254. A baffle 256 is welded to the outer wall of each set of baffles 254. Multiple sets of partitions 257 are fixed at equal intervals inside the baffles 256 along the width of the baffles 254. Soil-breaking blades 258 are welded to the front edge of the two sets of baffles 254. A diversion frame 251 connected to the hopper 110 is provided above the two sets of baffles 254. Two sets of conduits 255 that can convey fertilizer into the baffles 256 are connected to the bottom of the diversion frame 251.

[0020] The outer wall of the feeding roller 150 has three sets of notches 151 corresponding to each set of feeding ports 111. The three sets of notches 151 are equidistant from each other along the circumference of the feeding roller 150. Both ends of the feeding roller 150 extend to the outside of the hopper 110 and are fixed with connecting shafts 170. The outside of the hopper 110 is equipped with a drive motor 120 for driving the feeding roller 150 to rotate. The output end of the drive motor 120 is driven by a toothed synchronous belt 190 to the outer wall of the connecting shaft 170.

[0021] The outer wall of the hopper 110 is rotatably provided with two sets of driven toothed rings 180 that are fixed to the ends of the two sets of traction arms 131, and the two sets of driven toothed rings 180 are in a meshing connection state.

[0022] A discharge port 111 is provided at the bottom of the hopper 110 where it contacts each diversion frame 251. A guide plate 252 is fixed inside the diversion frame 251. A transfer frame 253 is connected to the bottom of the diversion frame 251. The bottom of the transfer frame 253 is connected to the bottom of the conduit 255.

[0023] It should be noted that: the driven gear ring 180 is fitted with a housing 160 on the outside. The housing 160 is fixed to the end face of the hopper 110 with screws, and the housing 160 also has a round hole for the connecting shaft 170 to rotate. Fertilizer is poured into hopper 110 and falls onto the surface of feed roller 150 by gravity. Drive motor 120 drives connecting shaft 170 to rotate through toothed synchronous belt 190, thereby driving feed roller 150 to rotate continuously. When feed roller 150 rotates, the notch 151 on its outer wall will periodically align with the feed port 111 at the bottom of hopper 110. When the notch 151 rotates to be directly above the feed port 111, the quantitative amount of fertilizer accumulated inside falls into the diversion frame 251 below through the feed port 111, realizing intermittent quantitative delivery of fertilizer. During the movement of the device, the soil-breaking blade 258 and the baffle 254 can open two trenches on the surface of the soil (the trenches are located on both sides of the sorghum seedlings, and since sorghum is planted using mechanical equipment, the soil-breaking blade 258 and the baffle 254 will not damage the sorghum seedlings when they move in a straight line), and then wait for the waste to fall off. Subsequently, the guide plate 252 guides the fertilizer to flow to both sides and finally into the transfer frame 253. Then, the fertilizer flows from the transfer frame 253 into the conduit 255, and is efficiently discharged from the conduit 255, accurately falling into the guide channel formed by the baffle plate 256 and the baffle 254. During this process, the partition plate 257 diverts the powdered fertilizer, dispersing it evenly, so that the fertilizer can fall evenly over a large area into the trench opened by the soil breaking plate 258 and the baffle 254. This effectively avoids direct contact between the fertilizer and the sorghum seedlings, thus preventing the seedlings from being burned due to excessive fertilizer concentration. Finally, with the assistance of the burying plate 280, the fertilizer is quickly buried in the soil, effectively reducing fertilizer evaporation due to exposure. Please refer to this carefully. Figure 4 and Figure 6 The fertilizer hopper assembly 100 also includes traction arms 131 fixed to both ends of each set of crushing grids 130. One end of the traction arm 131 is rotatably disposed on the inner wall of the hopper 110, and the outer wall of the hopper 110 is fitted with an electric push rod 140 capable of driving the traction arm 131 to swing. At the same time, the telescopic end of the electric push rod 140 extends, pushing the traction arm 131 connected to it to rotate around the connection point with the hopper 110. Simultaneously, two sets of driven gear rings 180 mesh, and another set of traction arms 131 connected to the driven gear ring 180 also rotates synchronously in the opposite direction. The rotation of the two sets of driven gear rings 180 drives the two sets of traction arms 131 fixed to them to swing in opposite directions, thereby precisely pulling the two sets of crushing grids 130 connected in an inclined manner in the hopper 110 to perform a scissor-like opening and closing action. When the crushing grids 130 approach each other, the grid bars on them efficiently squeeze and crush the clumps of fertilizer in the hopper 110, effectively preventing fertilizer from clogging the discharge port 111 and ensuring the continuity and smoothness of the feeding process; the crushed loose fertilizer is continuously supplied to the discharge roller 150 for quantitative conveying. The drive motor 120 runs continuously to ensure that the notch 151 of the feed roller 150 is periodically aligned with the feed port 111, thereby achieving stable intermittent conveying of fertilizer. The electric push rod 140 precisely adjusts the closing force of the crushing grid 130, and combined with the meshing transmission of the driven toothed ring 180, it efficiently crushes the clumps of fertilizer in the hopper 110, prevents blockage, and ensures the continuity and automation of the feeding process.

[0024] Please refer to this carefully. Figure 3 The support frame includes an upper frame beam 210 and a lower frame beam 220. Six sets of telescopic arms 260 are assembled between the upper frame beam 210 and the lower frame beam 220. Two pairs of rollers 230 capable of rolling are assembled at both ends of the lower frame beam 220. A traction frame 240 is fixed to the front surface of the upper frame beam 210.

[0025] The telescopic boom 260 can control the horizontal height of the bottom of the baffle 254, effectively adjust the excavation depth of the ditch, and ensure construction accuracy. When the equipment is traveling on the road, it can also actively protect the baffle 254 and the soil-breaking blade 258 to prevent them from being damaged by uneven road surface or external impact.

[0026] Please refer to this carefully. Figure 3 The support frame 200 also includes two sets of positioning plates 270 fixed to the front and rear inner walls of the upper frame beam 210. The upper surface of the positioning plates 270 has multiple sets of threaded holes 271 for fixing the baffles 254. The top of the baffle 254 is fixed with a positioning ear plate 259 for connection.

[0027] Multiple threaded holes 271 are distributed in different areas of the equipment, allowing the baffle 254 to be installed in different positions as needed, thus providing flexible space adjustment and ease of operation.

[0028] The outer wall of the upper frame beam 210 is fixed with a support plate 112 for supporting the drive motor 120 and the electric telescopic rod 140. The bottom of the electric telescopic rod 140 is rotatably connected to the support plate 120, and the drive motor 120 is fixed to the upper surface of the support plate 112 with bolts.

[0029] A fertilization method for a precision fertilization system for brewing sorghum includes the following steps: S1. Place the fertilizer for sorghum fertilization into the hopper 110 and spread it evenly to ensure uniform fertilizer distribution and facilitate subsequent operations; at the same time, adjust the spacing between the two sets of baffles 254 precisely according to the actual size of the sorghum seedling roots and stems so that the spacing matches the growth needs of the seedlings and avoids any mechanical damage to the roots, stems or leaves of the sorghum seedlings due to improper spacing; connect the traction frame 240 to the external fertilization equipment to start fertilizing the sorghum. S2. During fertilization, the soil-breaking blade 258 and the baffle 254 work together to precisely dig trenches on the ground, providing a basic path for fertilizer application. At the same time, the drive motor 120 drives the feed roller 150 to rotate continuously, achieving intermittent and quantitative delivery of fertilizer, ensuring that the fertilizer enters the diversion frame 251 at a controllable rhythm. Subsequently, the fertilizer is efficiently discharged by the guide tube 255 and accurately falls into the guide channel formed by the baffle 256 and the baffle 254. During this process, the partition 257 diverts the powdered fertilizer and disperses it evenly, allowing the fertilizer to fall evenly over a large area inside the trench. Finally, with the assistance of the burying plate 280, the fertilizer is quickly buried in the soil, effectively reducing fertilizer evaporation due to exposure. S3. When the drive motor 120 drives the feeding roller 150 to rotate, the coordinated work of the semi-toothed ring 171 and the driven toothed ring 180 can precisely pull the two sets of crushing grids 130 to perform scissor-like closing action, so that they approach each other and form extrusion pressure, which can efficiently squeeze and crush the clumps of fertilizer in the hopper 110, effectively preventing blockage problems. With the rotation of the feeding roller 150, a continuous and automated feeding function is realized, ensuring the smoothness and continuity of the fertilizer processing process. S4, the upper frame beam 210 and the lower frame beam 220 can adjust their positions to precisely control the distance between the bottom of the baffle 254 and the ground, thereby effectively adjusting the excavation depth of the ditch and ensuring construction accuracy. When the equipment is traveling on the road, it can also actively protect the baffle 254 and the soil-breaking piece 258 to prevent them from being damaged by uneven road surface or external impact.
