Description

Technical Field

[0001] This utility model relates to the field of fertilization equipment technology, specifically an agronomic fertilization machine. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, and enrich the soil.

[0003] A search revealed a Chinese patent for an agricultural fertilizer applicator, publication number CN221381712U, which includes a storage box, two collection slots, four conveying ports, two conveying plates, two lead screws, and two motors. The storage box is mounted on the upper part of the mounting plate, and the two collection slots are located on both sides of the lower end of the storage box.

[0004] The above-mentioned device uses a conveying and fertilizing structure that can continuously convey fertilizer in the storage box during fertilization operations, ensuring the fertilizer falling effect during the fertilization process. Through the set soil turning and covering structure, the soil on both sides of the plant roots can be turned over to completely cover the fertilizer, ensuring the overall use effect of the fertilizer. By adopting the combination of fertilization and soil turning, all the operations of fertilizing plants can be realized, thereby effectively increasing the overall efficiency of fertilization and the use effect of fertilizer.

[0005] However, the fertilizer falls out through the conveyor, and its discharge height and discharge volume are difficult to adjust, resulting in poor flexibility of use. In addition, the fertilizer may clump due to improper storage. The fertilizer is directly conveyed by pushing it through the conveyor plate, which is a relatively simple structure. When clumps of fertilizer block the discharge port, it is difficult to deal with them. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Combination Figures 1-4 An agricultural fertilizer applicator includes a storage box 1, a drive wheel set 2 at the bottom of the storage box 1, operating handles 3 installed on the front sides of the storage box 1, and a number of material storage chambers 4 inside the storage box 1.

[0027] See Figure 4Furthermore, a fertilizer pipe is installed at the bottom of the storage box 1 and at the center below each storage chamber 4. A flow control butterfly valve 6 is installed at the connection between the fertilizer pipe and the storage box 1. A discharge corrugated pipe 7 is connected to the bottom of the fertilizer pipe. A fixed rod is fixedly installed at the bottom of the storage box 1 and near the discharge corrugated pipe 7. A movable rod 8 is slidably installed at the bottom of the fixed rod. An adjusting block is fixedly connected at the center of the front end of the storage box 1. A movable frame 14 is movably installed at the front end of the adjusting block via a slider. A soil turning plow 15 is movably installed at the front end of the movable frame 14. A thrust spring 16 is installed at the top of the soil turning plow 15. The end of the thrust spring 16 away from the soil turning plow 15 is connected to the movable frame 14 via a pressure plate. A fixed insertion rod is installed at the top of the slider. Several fixed insertion holes 17 are arranged at equal intervals at the top of the adjusting block. The movable frame 14 is detachably connected to the adjusting block via the slider, the fixed insertion rod, and the adjusting block.

[0028] Specifically, before fertilization, various fertilizers can be stored in different storage chambers 4 as needed. Then, the storage box 1 can be moved by the set drive wheel set 2 to carry out the fertilization operation. During fertilization, the fertilizer is discharged into the discharge bellows 7 through the flow control butterfly valve 6. The discharge amount can be controlled by the set flow control butterfly valve 6 to adjust the fertilizer application. The position of the discharge port of the discharge bellows 7 can be adjusted by controlling the extension and retraction of the control rod 8 to stretch the discharge bellows 7, so as to avoid the discharge bellows 7 being too high above the ground, which would cause the fertilizer to scatter. During the fertilization process, the set soil turning plow head 15 can turn the soil to cover the fertilizer.

[0029] Example 2

[0030] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, a transmission wheel 10 is rotatably installed at the top of the storage box 1 and at the center above each storage chamber 4. An anti-caking stirring rod 5 is rotatably installed inside the storage chamber 4 via a rotating rod. The top of the anti-caking stirring rod 5 is connected to the bottom of the transmission wheel 10. A transmission toothed belt 12 is fitted around the outer ring of several transmission wheels 10. A stirring motor 11 is installed on the rear side of the top of the storage box 1 via a support plate. The drive shafts of the two stirring motors 11 are respectively connected to the top of the two transmission wheels 10. A feed inlet 13 is provided at the top of the storage box 1 and at one side above each storage chamber 4. The drive shaft of the stirring motor 11 is connected to the transmission toothed belt 12 and the anti-caking stirring rod 5 via the transmission wheel 10. The outer ring of the anti-caking stirring rod 5 does not contact the inner wall of the storage chamber 4.

[0031] Specifically, when fertilizer is added into the storage chamber 4 through the inlet 13, the stirring motor 11 can be started. Since the drive shaft of the stirring motor 11 is connected to the rotating rods of several anti-caking stirring rods 5 through the transmission toothed belt 12 and the transmission wheel 10, it can drive several anti-caking stirring rods 5 to rotate continuously in the storage chamber 4, so as to break up the caking fertilizer and prevent it from caking and blocking the fertilizer outlet. When applying multiple mixed fertilizers, the continuous rotation of the anti-caking stirring rods 5 can stir the fertilizer to improve its mixing uniformity. Furthermore, the stirring of the anti-caking stirring rods 5 prevents the fertilizer from remaining static in the storage chamber 4, which can further reduce the probability of fertilizer getting stuck.

[0032] In actual operation, before fertilization, various fertilizers can be stored in different storage chambers 4 as needed. Then, the storage box 1 can be moved by the set drive wheel group 2 to carry out fertilization operation. During fertilization, the fertilizer is discharged from the flow control butterfly valve 6 into the discharge bellows 7. The amount of material discharged can be controlled by the set flow control butterfly valve 6, thereby adjusting the amount of fertilizer applied.

[0033] Furthermore, by controlling the extension and retraction of the movable rod 8 to stretch the discharge corrugated pipe 7, the position of the discharge port of the discharge corrugated pipe 7 can be adjusted. During adjustment, the locking knob 9 at the movable rod 8 can be loosened to release the locking of the movable rod 8. Then, the movable rod 8 can be pulled away from the fixed rod until it is adjusted to a suitable position. After that, the locking knob 9 is tightened again to fix it. This adjustment can prevent the discharge corrugated pipe 7 from being too high above the ground or too close to the crops, thus preventing fertilizer from scattering and reducing the probability of the discharge corrugated pipe 7 colliding with plants. During the fertilization process, the soil turning plow 15 can be used to turn the soil so as to cover the fertilizer.

[0034] When fertilizer is added into storage chamber 4 from feed inlet 13, stirring motor 11 can be started. Since the drive shaft of stirring motor 11 is connected to the rotating rods of several anti-caking stirring rods 5 through transmission tooth belt 12 and transmission wheel 10, it can drive several anti-caking stirring rods 5 to rotate continuously in storage chamber 4 so as to break up the caking fertilizer and prevent it from caking and blocking fertilizer outlet.

[0035] Furthermore, when applying multiple mixed fertilizers, the continuous rotation of the anti-caking stirring rod 5 can stir the fertilizers to improve their mixing uniformity. Moreover, the stirring of the anti-caking stirring rod 5 prevents the fertilizers from remaining static in the storage chamber 4, which can further reduce the probability of fertilizers getting stuck and facilitates improved fertilization effect.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
