Technical Field
[0001] This utility model relates to the field of grain and oil crop technology, and more specifically, to a fertilization device based on reducing fertilizer use and increasing efficiency in grain and oil crops. Background Technology
[0002] In the cultivation of grain and oil crops, scientific fertilization is a key link in improving yield and quality. However, excessive use of chemical fertilizers not only leads to soil compaction and decreased fertility but may also cause environmental problems such as eutrophication of water bodies. Therefore, reducing fertilizer use and increasing efficiency has become an important direction for modern agricultural development. Existing fertilization devices have many shortcomings in practical application: Firstly, most devices struggle to achieve precise proportioning and uniform mixing of solid and liquid fertilizers, resulting in low fertilizer utilization rates and requiring excessive application to meet crop needs. Secondly, traditional fertilization devices often lack precise control over the amount of fertilizer applied, easily leading to localized over- or under-fertilization, affecting crop absorption. Furthermore, some devices do not consider soil pretreatment before fertilization, applying fertilizer directly to the surface of compacted soil, making it difficult to penetrate the root zone and further reducing the effective utilization rate of fertilizer. Simultaneously, the fertilizer delivery structure design of existing devices is not reasonable enough; solid fertilizer is prone to residue and blockage, and the flow rate of liquid fertilizer is unstable. Overall, the ease of operation and adaptability are poor, failing to fully meet the precise fertilizer needs of grain and oil crops at different growth stages, thus hindering the achievement of the goal of reducing fertilizer use and increasing efficiency.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Please see Figures 1-4 This utility model provides a technical solution: a fertilization device for reducing fertilizer use and increasing efficiency in grain and oil crops, including a support plate 110, a solid fertilizer tank 120 and a liquid fertilizer tank 130 symmetrically fixedly installed on the top of the support plate 110, a screw feeder installed inside the solid fertilizer tank 120, a liquid outlet pipe 131 installed on one side of the liquid fertilizer tank 130, a first valve installed on the liquid outlet pipe 131, a mixing tank 140 fixedly installed at the bottom of the support plate 110, a feed inlet connected to the top of the mixing tank 140 and the support plate 110, a stirring assembly installed inside the mixing tank 140, and multiple nozzles 141 fixedly installed at the bottom of the mixing tank 140, each nozzle 141 having a flow valve installed on it.
[0029] In some specific implementation schemes, feed pipes are fixedly installed on the solid fertilizer tank 120 and the liquid fertilizer tank 130, and feed hoppers are installed on the feed pipes. The feed hoppers expand the receiving area of the feed inlet, making it convenient for operators to quickly and easily add solid and liquid fertilizers to the two tanks, reducing fertilizer spillage and waste during the addition process. At the same time, the combination structure of the feed pipes and feed hoppers also facilitates the control of the addition process, improving the feeding efficiency and ease of operation of the device.
[0030] In some specific implementation schemes, the screw conveyor includes a first auger 121 and a first motor 122. The bottom sides of the inner wall of the solid fertilizer box 120 are inclined, and an arc-shaped groove is provided in the center. The first auger 121 is rotatably installed on one side of the arc-shaped groove, and the first motor 122 is installed at one end of the first auger 121. A discharge hole that cooperates with the first auger 121 is provided on one side of the solid fertilizer box 120. The first motor 122 is fixedly installed on the outside of the solid fertilizer box 120, and the output end of the first motor 122 passes through one side of the solid fertilizer box 120 and is fixedly connected to one end of the first auger 121. This allows the solid fertilizer to collect in the arc-shaped groove under its own gravity, avoiding residue accumulation. The first motor 122 drives the first auger 121 to rotate, which can stably and evenly push the solid fertilizer to the discharge hole, realizing the quantitative delivery of solid fertilizer. This solves the problems of uneven delivery and easy clogging of traditional solid fertilizer, provides a guarantee for precise control of solid fertilizer dosage, and helps to reduce fertilizer use and increase efficiency.
[0031] In some specific implementation schemes, a guide plate 123 is fixedly installed on the outside of the discharge port. The guide plate 123 is inclined and has a guide groove at its top. One end of the guide plate 123 extends into the inlet, and one end of the liquid outlet pipe 131 is positioned above the inlet. The guide groove guides the solid fertilizer discharged from the discharge port, preventing fertilizer from scattering. The extension of one end of the guide plate 123 into the inlet allows the solid fertilizer to be accurately introduced into the mixing tank 140. At the same time, the positioning of one end of the liquid outlet pipe 131 above the inlet allows the liquid fertilizer to also accurately enter the mixing tank 140. This ensures a stable conveying path for both solid and liquid fertilizers before they enter the mixing tank 140, reduces fertilizer loss, and improves the accuracy of fertilizer delivery.
[0032] Please see Figure 4The mixing assembly includes a rotating shaft 142 and a second motor 143. The rotating shaft 142 is rotatably mounted between the two sides of the inner wall of the mixing tank 140. The second motor 143 is mounted on one end of the rotating shaft 142. Multiple stirring rods 144 are fixedly mounted on the rotating shaft 142 in a staggered manner. The second motor 143 is fixedly mounted on one side of the mixing tank 140, and its output end passes through the mixing tank 140 and is fixedly connected to one end of the rotating shaft 142. This process breaks up fertilizer clumps, ensures uniform mixing of fertilizers with different components, improves the overall fertility of the fertilizer, ensures balanced fertilizer absorption by crops, and helps reduce fertilizer usage and improve utilization efficiency.
[0033] In some specific implementation schemes, the bottom of the mixing tank 140 is arc-shaped, and two second augers 145 are fixedly installed at both ends of the rotating shaft 142, with the two second augers 145 arranged symmetrically. When the second augers 145 rotate, they can push the mixed fertilizer in the mixing tank 140 towards the middle or sides of the tank, forming a circulating mixing effect, avoiding local accumulation of mixed fertilizer at the bottom of the tank, and further improving the uniformity of fertilizer mixing; at the same time, the arc-shaped bottom design also facilitates the collection of mixed fertilizer towards the nozzle 141, reducing residue and ensuring full utilization of fertilizer.
[0034] Please see Figure 4 and Figure 6 A U-shaped bracket 111 is symmetrically fixed to both sides of the bottom of the support plate 110, and a pulley 112 is installed at the bottom of the bracket 111. The pulley 112 allows the device to move flexibly, facilitating fertilization operations in different areas of the field, reducing the labor intensity of operators, and improving the flexibility and efficiency of fertilization operations. A horizontal plate 113 is fixedly installed between the two sides of the inner wall of the bracket 111, and a battery box 114 is installed at the top of the horizontal plate 113. The battery box 114 is electrically connected to the first motor 122 and the second motor 143. It can provide continuous and stable power support for both motors, ensuring the normal operation of the screw conveyor and the mixing assembly, avoiding the impact of limited external power supply on fertilization operations, and improving the independence and applicability of the device.
[0035] In some specific implementation schemes, a sleeve plate 150 is fixedly installed between two supports 111. The bottom end of the sleeve plate 150 is slidably fitted with a vertical plate 151. Electric push rods 152 are symmetrically fixedly installed at the top end of the sleeve plate 150. The output end of the electric push rod 152 passes through the sleeve plate 150 and is fixedly connected to the top end of the vertical plate 151. Multiple shovel plates 153 are fixedly installed at the bottom end of the vertical plate 151. One side of the shovel plate 153 is inclined. The electric push rod 152 can drive the vertical plate 151 to slide up and down, causing the shovel plate 153 to insert into the soil and perform loosening operations. The inclined setting on one side of the shovel plate 153 is more conducive to cutting into the soil. The loosened soil is easier for fertilizer to penetrate and absorb, improving fertilizer utilization. At the same time, no additional soil loosening equipment is needed. The integrated design enhances the multifunctionality and practical value of the device.
[0036] Working principle: During use, solid and liquid fertilizers are added to the solid fertilizer tank 120 and liquid fertilizer tank 130 respectively through the feed pipes with feed hoppers. The battery box 114 provides power to the first motor 122, the second motor 143, and the electric push rod 152. Inside the solid fertilizer tank 120, the first motor 122 drives the first auger 121 to rotate. Due to the inclined sides of the bottom of the inner wall of the tank and the arc groove in the center, the solid fertilizer will collect in the arc groove and be pushed to the discharge port by the first auger 121. Then, it is inclined and introduced into the feed port of the mixing tank 140, which is connected to the support plate 110, through the guide plate 123 with the guide groove. After the first valve of the liquid outlet pipe 131 on one side of the liquid fertilizer tank 130 is opened, the liquid fertilizer flows from one end of the liquid outlet pipe 131 to the top of the feed port and enters the mixing tank 140. Inside the mixing tank 140, the second motor 143 drives the rotating shaft 142 to rotate. The interlaced stirring rods 144 on the rotating shaft 142 stir and mix the incoming solid and liquid fertilizer. At the same time, the second augers 145 at both ends of the rotating shaft 142 rotate symmetrically, working in conjunction with the arc-shaped bottom of the mixing tank 140 to push the mixed fertilizer towards the tank body for multiple mixing and stirring. Finally, the amount of fertilizer applied can be controlled by the flow valve on the nozzle 141. In addition, the U-shaped brackets 111 on both sides of the bottom end of the support plate 110 are connected by pulleys 112 to facilitate the movement of the device. The electric push rods 152 on the sleeve plates 150 between the brackets 111 can push the vertical plate 151 to slide up and down, so that the inclined shovel plate 153 on one side of the bottom end of the vertical plate 151 loosens the soil before fertilization, which facilitates fertilizer absorption and achieves reduced fertilizer use and increased efficiency for grain and oil crops.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
