The inner cylinder 4 is detachably mounted inside the material spreading mechanism 3 through the assembly part 42 . The material discharge device 43 is detachably mounted at the material discharge end of the inner cylinder 4 .

[0022] By setting the inner cylinder 4, during fertilization, the fertilizer applied each time is stored in the inner cylinder 4. After the fertilization of the planting sites to be fertilized is completed, when there is still excess fertilizer in the inner cylinder 4, the inner cylinder 4 is unlocked from the supporting cylinder 2, and then the inner cylinder 4 can be directly removed, and the fertilizer in the inner cylinder 4 can be poured into a storage bag for storage, so as to facilitate taking out the excess fertilizer, be convenient to use, and facilitate cleaning of the inside of the inner cylinder 4, so as to avoid the fertilizer from adhering to the barrel for a long time and corroding the barrel, thereby extending the service life of the inner cylinder 4 and avoiding residual fertilizer from polluting the environment.

[0023] After the fertilizer is poured out, the inner cylinder 4 is assembled with the supporting cylinder 2 .

When the fertilization step is entered, the rotating device drives the rotating shaft 432 to rotate, and the rotating shaft 432 drives multiple discharge plates 433 to rotate. The discharge plates 433 drive the fertilizer inside the inner cylinder 4 to flow downward at a uniform speed, and enter the spreading mechanism 3 from the discharge port 4311 to perform the spreading operation, thereby ensuring the uniform discharge of the fertilizer and avoiding blockage.

[0061] See also Figures 1 to 3 as well as Figure 7 In this embodiment, the reciprocating device is a driving frame 73, and the driving frame 73 is installed on the sliding sleeve 72. A driving shaft 351 is eccentrically installed at the bottom of the slave gear 35, and the driving shaft 351 extends into the interior of the driving frame 73 away from one end of the slave gear 35.

[0062] During fertilization, when the motor 332 drives the spreading plate 32 to rotate through the main gear 333 and the slave gear 35, the slave gear 35 drives the driving shaft 351 to rotate. During the rotation of the driving shaft 351, it slides along the inside of the driving frame 73 and pushes the driving frame 73 to reciprocate, such as Figure 7 (a) and Figure 7 (b); the driving frame 73 drives the sleeve 72 to reciprocate, and the sleeve 72 drives the toggle rod 76 to reciprocate through the connecting arm 74 and the main rod 75, that is, the driving device 33 drives the spreading plate 32 to rotate to realize the function of driving the soil-moving device 7 to reciprocate.

[0064] The working principles of the premixed organic fertilizer spreading device and fertilization method based on reducing fertilizer application and increasing efficiency provided by the present invention are as follows: By setting the inner cylinder 4, during fertilization, the fertilizer applied each time is stored in the inner cylinder 4. After the fertilization of the planting land to be fertilized is completed, when there is still excess fertilizer in the inner cylinder 4, the inner cylinder 4 is unlocked from the carrying cylinder 2, and then the inner cylinder 4 can be directly removed, and then the fertilizer in the inner cylinder 4 can be poured into the storage bag for storage, which is convenient for taking out the excess fertilizer, easy to use, and convenient for cleaning the inside of the inner cylinder 4, so as to avoid the fertilizer from adhering to the material barrel for a long time and corroding the material barrel, prolonging the service life of the inner cylinder 4, and avoiding residual fertilizer from polluting the environment; In particular, during use, the frame 1 is installed with a tractor, and the tractor drives the entire spreading device to move along the planting field. When fertilizing, the bottom tapered portion of the toggle rod 76 is inserted into the soil. When the tractor drives the entire spreading device to move, the toggle rod 76 moves the soil. During the fertilization process, the motor 332 drives the main gear 333 to rotate, and the main gear 333 drives the spreading disc 32 to rotate through the slave gear 35, thereby driving the spreading disc 32 to rotate; at the same time, the motor 332 drives the transmission shaft 51 to rotate through the main bevel gear 54 and the slave bevel gear 53, and the transmission shaft 51 drives the assembly block 52 to rotate, and the assembly block 52 drives the rotating shaft 432 to rotate through the U-shaped sleeve 434, thereby driving the unloading plate 433 to rotate, and the fertilizer inside the cylinder 41 is transported downward to the rotating spreading disc 32 for spreading; In this process, the slave gear 35 drives the driving shaft 351 to rotate. During the rotation of the driving shaft 351, the driving shaft 351 slides along the inside of the driving frame 73 and pushes the driving frame 73 to move back and forth. Figure 7 (a) and Figure 7 (b); the driving frame 73 drives the sliding sleeve 72 to move back and forth, and the sliding sleeve 72 drives the toggle rod 76 to move back and forth through the connecting arm 74 and the main rod 75, so that the soil can be turned over, the soil and fertilizer are mixed, the fertilizer can be better dissolved in the soil, and the air permeability and water retention of the soil can be improved.

[0065] The present invention also provides a fertilization method of premixed organic fertilizer based on reducing the use of chemical fertilizers and increasing their efficiency, comprising the following steps: S1: According to soil fertility and crop requirements, premixed organic fertilizers are used together with chemical fertilizers to form mixed fertilizers; S2: Before planting, the mixed fertilizer is spread on the planting site using the premixed organic fertilizer spreading device based on reducing the use of chemical fertilizers and increasing their efficiency; S3: Apply mixed fertilizer in multiple times according to the growth stage and fertilizer requirements of the crops.

[0066] In this embodiment, the premixed organic fertilizer refers to an organic fertilizer prepared by premixing a variety of organic raw materials according to a certain formula and ratio during the production process and undergoing a treatment process such as composting and fermentation.

[0067] Among them, the mixing ratio of premixed organic fertilizer and chemical fertilizer can be 1:1; it can be specifically set according to factors such as soil fertility, crop type, and climatic conditions. For example, for low-fertility soil, the proportion of organic fertilizer is increased.

[0068] Organic fertilizer can provide a long-term supply of nutrients, while chemical fertilizer can quickly meet the short-term nutrient needs of crops. The combination of the two can not only reduce the amount of chemical fertilizer used, but also ensure the nutrient supply of crops. According to the growth stage and fertilizer requirements of the crops, organic fertilizer can be applied in multiple times, thereby reducing the use of fertilizers, improving the utilization rate of fertilizers, and achieving the effect of reducing application and increasing efficiency.

[0069] For the use of fertilizers in multiple times, apply an appropriate amount of mixed fertilizer in the early stage of crop growth to promote the growth of seedlings; supplement it again during the vigorous growth period and fruiting period to meet its peak nutrient needs. Of course, fertilization operations can be carried out at other times according to the needs of different crops.

[0070] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
