Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an anti-clogging fertilizer discharge device for agricultural machinery. Background Technology

[0002] With the popularization of large-scale planting, agricultural machinery operations need to take into account both efficiency and precision. Due to the limitations of structural design, traditional fertilizer discharge devices have long faced three major pain points: frequent clogging, low fertilization efficiency, and serious fertilizer waste. These have become key issues restricting the quality and efficiency of field operations, and have also spurred the research and development of anti-clogging fertilizer discharge devices.

[0003] The fertilizer discharging devices used in agricultural machinery currently consist mainly of a hopper, a hopper cover, a feed hopper, a fertilizer outlet, and a support frame. They are suitable for large-scale field crop planting, precision planting of cash crops, complex field environment operation, and other scenarios.

[0004] While current agricultural machinery fertilizer discharge devices effectively discharge fertilizer, traditional devices rely on gravity for natural discharge, which easily leads to accumulation and blockage in the discharge port and conveying pipes. Furthermore, they cannot control the discharge volume during fertilization. Therefore, an anti-clogging agricultural machinery fertilizer discharge device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging fertilizer discharge device for agricultural machinery, which aims to improve the problems of easy accumulation and blockage inside traditional fertilizer discharge devices and the inability to control the discharge during fertilization.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1-5 This utility model provides an embodiment of an anti-clogging fertilizer discharge device for agricultural machinery, comprising a hopper 1, with an inlet hopper 20 fixedly connected to the top of the hopper 1. The upper opening of the inlet hopper 20 is designed to be wider than the lower opening, facilitating farmers to pour fertilizer smoothly and preventing fertilizer from spilling outside the hopper 1 during addition. The fixed connection between the inlet hopper 20 and the hopper 1 is very strong, capable of withstanding the impact force when fertilizer is poured in, ensuring no loosening or displacement during operation. An inlet 3 is provided inside the inlet hopper 20. A sieve plate 9 is fixedly connected inside the hopper 1, installed in the middle of the hopper 1, precisely catching the fertilizer falling from the inlet 3. The main function of the sieve plate 9 is to filter out large clumps or impurities in the fertilizer in advance, preventing these substandard fertilizers from entering the hopper. The material entering the subsequent conveying stage causes blockage, and the screen plate 9 is fixed in a very stable way, which can withstand the weight of the fertilizer falling on it, and will not shake or deform during operation. The top of the screen plate 9 has multiple separation holes 10. The diameter of the separation holes 10 is designed according to the particle size of commonly used fertilizers. Only fertilizer particles that meet the particle size requirements can pass through the separation holes 10 and enter the subsequent stage at the bottom of the hopper 1. The top of the screen plate 9 is fixedly connected to the bearing seat 5, the top of the bearing seat 5 is equipped with a drive motor 6, the top of the drive motor 6 is rotatably connected to the spiral shaft 7, and the outside of the spiral shaft 7 is fixedly connected to the spiral blades 8. The bottom of the hopper 1 is fixedly connected to the separation chamber 11, and the inside of the separation chamber 11 is fixedly connected to the mounting base 12. The bottom of the mounting base 12 is equipped with a star wheel assembly.

[0013] Reference Figure 4 and Figure 5The star wheel assembly includes a star wheel shaft 13, with the top of the star wheel shaft 13 fixedly connected to the bottom of the mounting base 12. Multiple slots 14 are provided on the outer side of the star wheel shaft 13, and a locking block 15 is slidably connected to the outer side of the star wheel shaft 13. The locking block 15 is slidably connected inside the slots 14, and a star wheel blade 17 is fixedly connected to the top of the locking block 15. When the star wheel shaft 13 drives the locking block 15 to rotate, the star wheel blade 17 will also rotate synchronously. The gap between the blades can separate the fertilizer in the separation chamber 11, and then send the fertilizer to the discharge port as it rotates. A rotating screw 16 is threadedly connected to the top of the star wheel blade 17.

[0014] Reference Figure 2 and Figure 3 The top of the feed hopper 20 is rotatably connected to a cover 2. When farmers add fertilizer, they can rotate the cover 2 upwards to open it, making it easy to pour the fertilizer into the feed hopper 20. After adding fertilizer, the cover 2 is rotated to close, which can isolate moisture, dust and impurities in the field. The bottom left and right sides of the cover 2 are provided with positioning grooves 23. The bottom of the cover 2 is fixedly connected to a positioning post 22, which is rotatably connected inside the positioning groove 23. The positioning post 22 is hinged to a hinge shaft 21 inside the positioning post 22, which is fixedly connected to the outside of the cover 2. The right side of the separation chamber 11 is fixedly connected to a bracket 18. The bracket 18 is provided with mounting holes 19 on both the left and right sides. When installing, farmers only need to pass the bolts through the mounting holes 19 and tighten them to the fixing points on the agricultural machinery body to firmly fix the bracket 18 to the agricultural machinery. The separation chamber 11 is provided with a fertilizer outlet 4. The spiral blades 8 are made of 304 stainless steel.

[0015] Working principle: Fertilizer is introduced into hopper 1 through feed hopper 20. Hopper cover 2 opens and closes via hinge shaft 21. When closed, positioning pin 22 engages with positioning groove 23 to achieve a sealed position, preventing fertilizer from absorbing moisture and clumping, and ensuring the fertilizer inlet 3 is aligned with the feed. Next, bracket 18 is fixed to the agricultural machinery via mounting base 12 and mounting hole 19. Drive motor 6 drives the spiral shaft 7, supported by bearing seat 5, to rotate. Spiral blades 8 rotate with the shaft, forcibly pushing the fertilizer inlet 3 at the top of hopper 1 to separation hopper 11. Simultaneously, clumps of fertilizer that are difficult to remove are broken into separable small pieces by the high-speed rotation of the spiral blades 8. After entering the separation chamber 11, the fertilizer falls onto the screen plate 9. Particles that meet the particle size requirements leak through the separation holes 10 to the bottom of the chamber, while large impurities continue to be separated multiple times by the spiral blades 8 in the hopper 1. Finally, the star wheel shaft 13 drives the star wheel blades 17 to rotate. The amount of fertilizer discharged is controlled by controlling the tilt angle of the star wheel blades 17. The star wheel blades 17 can be changed at different angles on the star wheel shaft 13 through the slots 14 and the blocks 15. After the change is completed, the blocks 15 and the star wheel blades 17 are fixed on the star wheel shaft 13 by the rotating screw 16, which avoids blockage from the source and achieves stable and accurate fertilizer discharge.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
