[0001] The present invention relates to the technical field of fertilizer applicators, and particularly to a soil fertilizing device and a fertilizing method for cereal planting. Background Art

[0002] Cereal planting has been gradually replaced by mechanization. Compared with manual work, large-scale planting can no longer meet the planting requirements. Therefore, at present, plowing, fertilizing, and sowing all have to rely on machinery to be completed. For fertilizer applicators, the centrifugal fertilizer spreader is the most commonly used spreading implement. It is a fertilizer spreader that uses a centrifugal force generated by a fertilizer spreading disc driven by a power output shaft to spread chemical fertilizers, and there are two types: single-disc type and double-disc type. However, regardless of the single-disc type or the double-disc type, the spreading disc cannot be adjusted in angle, resulting in the inability to adjust the spreading range. For this reason, we propose a soil fertilizing device and a fertilizing method for cereal planting. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figures 1 to 6 , the present invention provides a technical solution: a soil fertilization device for cereal planting, including a walking vehicle body, as Figure 3 and Figure 4 shown, the walking vehicle body includes a support frame 1. On both sides of one end of the support frame 1, there are respectively connected supports 2. The upper and lower ends of the supports 2 are respectively exposed outside the support frame 1. At the bottom of each support 2, there is respectively installed a walking wheel 3;

[0028] One end of the support frame 1 away from the walking wheel is connected to a hanging rack. The hanging rack is used for connecting with agricultural machinery. The hanging rack is a V-shaped rack 17 installed at one end of the support frame 1. At the end of the V-shaped rack 17, there is a connecting seat 18. There is a hanging hole on the connecting seat 18. During use, drag the V-shaped rack 17, place the connecting seat 18 into the hook at the tail of the agricultural machine, and then connect it with a bolt. At this time, driving the agricultural machine can drive the walking vehicle body to travel.

[0029] On the top of the walking vehicle body, there is a material hopper 16, that is, the material hopper 16 is arranged above the support frame 1. Both sides of the material hopper 16 are respectively connected to the support frame 1 through the first fixing frame 19. On one side of the bottom of the material hopper 16 away from the hanging rack, there is connected a material lifting mechanism. The material lifter includes a screw lifter 15. The inlet 24 at the bottom of the screw lifter 15 is connected to the discharge channel 21. The discharge channel 21 is arranged at the bottom of the side of the material hopper 16;

[0030] As Figure 4 shown, inside the support frame 1, there is a support frame body 23 that holds the material hopper 16. And the bottom surface of the material hopper 16 and the top surface of the support frame body 23 are both inclined surfaces that slope towards the screw lifter 15. The discharge channel 21 is arranged at the bottom of the inclined surface, so that the fertilizer in the material hopper 16 can automatically gather towards the discharge channel 21 along the inclined surface. At the top of the screw lifter 15, there is an outlet 14. Therefore, when the screw lifter 15 rotates, it can drive the fertilizer in the material hopper 16 to be lifted upwards, and finally the fertilizer continuously flows out from the outlet 14;

[0031] In order to make the screw lifter 15 stable, the screw lifter 15 is fixed to the side of the material hopper 16 through the second fixing frame 20, so that the screw lifter 15 is supported.

[0032] Immediately afterwards, as Figure 1 and Figure 2As shown, on one side of the material lifting mechanism away from the material hopper 16, there is an installation frame 11. There is a certain distance between the installation frame 11 and the material lifting mechanism to prevent them from touching. In the middle of the installation frame 11, there is a fertilizer spreading device corresponding to the material lifter. The fertilizer spreading device includes a driving motor 9 installed at the middle of the bottom of the installation frame 11;

[0033] Above the top of the installation frame 11, there is a spreading disc 12. The spreading disc 12 is coaxially installed on the rotating top of the driving motor 9. As Figure 2 shown, the outlet 14 is located above the spreading disc 12 and there is a certain distance between them to prevent them from touching. In this way, the fertilizer flowing out of the outlet 14 can directly fall on the spreading disc 12. At the edge of the spreading disc 12, there are arc-shaped blades 25. Grooves are formed between the arc-shaped blades 25. After the fertilizer falls into the grooves, it is thrown out with the centrifugal force;

[0034] Among them, the installation frame 11 can rotate. When the installation frame 11 rotates, it can drive the spreading disc 12 to adjust the angle. That is, rotating shafts 7 are respectively connected to both ends of the installation frame 11. The two rotating shafts 7 are respectively connected to the ends of the support arms 8. The end of the support arm 8 away from the rotating shaft 7 is connected to the walking vehicle body. Specifically, the support arm 8 is fixed to the support 2;

[0035] On one of the support arms 8, there is a driving mechanism connected to the rotating shaft 7. The driving mechanism is used to drive the rotating shaft 7 to adjust the angle. The specific structure of the driving device includes a driving arm 10 radially installed at the end of the rotating shaft 7. The end of the driving arm 10 away from the rotating shaft 7 is rotatably connected to the telescopic mechanism 6. The end of the telescopic mechanism 6 away from the driving arm 10 is connected to the first connecting frame 5. The first connecting frame 5 is arranged on the side of the support arm 8;

[0036] The telescopic mechanism 6 is one of a hydraulic cylinder, a pneumatic cylinder or an electric telescopic cylinder. In this application, the telescopic mechanism 6 is preferably a hydraulic cylinder. The advantage is that the hydraulic cylinder has the greatest supporting force and can meet the requirements of large load capacity. When the telescopic mechanism 6 expands and contracts, the telescopic mechanism 6 drives the driving arm 10 to rotate, and the driving arm 10 will drive the rotating shaft 7 to rotate, so that the rotating shaft 7 drives the installation frame 11 to flip;

[0037] The specific situation of spreading fertilizer is as Figure 6 shown. When the spreading disc 12 tends to be horizontal, the spreading area is wide. When the angle between the spreading disc 12 and the horizontal becomes larger, the spreading area of the spreading disc 12 becomes smaller. Therefore, by controlling the expansion and contraction of the telescopic mechanism, the spreading disc 12 can be driven to adjust the angle, so as to control the spreading area of the spreading disc 12.

[0038] Furthermore, in order to prevent the fertilizer from being thrown to the driver, as Figure 3 and Figure 4As shown in the figure, an arc-shaped baffle 13 is provided on one side of the spreading plate 12 close to the spiral elevator 15. The spreading plate 12 is placed inside the arc-shaped baffle 13 and the two are in clearance fit. The two ends of the spreading plate 12 are respectively connected with second connecting frames 22 extending to the mounting frame 11, and the second connecting frames 22 are mounted on the mounting frame 11. The arc-shaped baffle 13 surrounds the spreading plate 12 by no more than 180°, preventing the spreading plate 12 from being blocked when spreading fertilizer. Therefore, the fertilizer on the spreading plate 12 can only spill out from the opening of the arc-shaped baffle 13 and will not be thrown onto the driver.

[0039] Based on the above embodiment, it can be further optimized that a reinforcing frame 4 is provided under each support arm 8. One end of the reinforcing frame is connected to the support arm 8 and the other end is connected to the support. The support 2, the reinforcing frame 4 and the support arm 8 form a triangular structure.

[0040] Based on the above embodiment, it can be further optimized that a power generation device or a rechargeable battery pack is provided on the agricultural machine, and the power generation device or the rechargeable battery pack supplies power to the hydraulic drive device, the spiral elevator 15 and the drive motor 9.

[0041] Furthermore, the present application also proposes a fertilization method for a soil fertilization device for cereal planting, including the following steps:

[0042] Step 1: Connect the hanging frame to the agricultural machine so that the agricultural machine can pull the walking vehicle body forward;

[0043] Step 2: Pour the fertilizer into the hopper 16 for storage, and then drive the agricultural machine to the planting field for fertilization;

[0044] Step 3: Start the drive motor 9 to rotate the spreading plate 12, and then start the spiral elevator 15 to continuously transport the fertilizer in the hopper 16 to the outlet 14. The fertilizer falls from the outlet 14 onto the spreading plate 12, and the centrifugal force generated by the spreading plate 12 spreads the fertilizer;

[0045] Step 4: The driver can control the telescopic movement of the telescopic mechanism 6 to control the tilting angle of the spreading plate, thereby controlling the spreading range of the spreading plate.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
