[0002] Fertilizer refers to a substance that is applied to the soil or sprayed on the above-ground parts of crops, which can directly or indirectly provide essential nutrients for crops, thereby increasing yields, improving quality, or improving soil properties and enhancing soil fertility. It can be classified according to its source into: chemical fertilizers, organic fertilizers and biological fertilizers. Organic fertilizers refer to fertilizers that mainly come from organic matter such as animal and plant residues and excrement, which are applied to the soil after a certain processing to provide the nutrients needed for plant growth.

[0003] Fertilizer preparation equipment refers to equipment or systems used to convert organic or inorganic raw materials into fertilizers, and is widely used in agriculture, horticulture, environmental protection and other fields. Depending on the type of raw materials, preparation process and target fertilizer form, the design and function of the equipment will also vary. Fertilizer preparation equipment can be divided into chemical fertilizer preparation equipment and organic fertilizer preparation equipment, among which organic fertilizer preparation equipment can be divided into raw material processing equipment, fermentation equipment, granulation equipment, granulation equipment, screening and packaging equipment, etc.

[0016] A method for preparing fertilizer comprises the following steps: S1. Particle forming: Pour the fermented organic fertilizer into the disc, power on and start the first motor, the output end of the first motor drives the first driving gear to rotate, the first driving gear drives the first driven gear to rotate by meshing with the first driven gear, the first driven gear drives the first shaft to rotate, the first shaft drives the disc to rotate, so that the organic fertilizer in the disc is rolled and stacked, and is aggregated from dispersed small molecules to granules, the organic fertilizer particles reciprocate on the disc, and at the same time, the granular organic fertilizer particles move from the center to the edge of the disc under the centrifugal force generated by the rotation of the disc, and gradually form a particle arrangement from small to large, so as to realize the particle forming of the organic fertilizer; S2. Particle extraction: The organic fertilizer particles are arranged from small to large, and the negative pressure pump is powered on to start the negative pressure pump, which extracts the gas in the straw, so that a negative pressure state is formed in the straw. The plug-in end of the straw extracts the organic fertilizer particles in the disc, so that the organic fertilizer particles in the disc are extracted into the material box, thereby realizing the extraction of the organic fertilizer particles; S3, Adjustment extraction: During the extraction of organic fertilizer particles, the first electric push-pull rod is powered on, and the output end of the first electric push-pull rod contracts to pull the ratchet and the adapter block to deflect, and the ratchet is released from the engagement and lock with the ratchet wheel, and the second motor is powered on, and the output end of the second motor drives the second driving gear to rotate, and the second driving gear drives the second driven gear to rotate by meshing with the second driven gear, and the second driven gear drives the second shaft rod to rotate, and the second shaft rod drives the ratchet and the deflection rod to deflect, and at the same time, the guide block limits the deflection range of the straw plug-in end by cooperating with the guide groove, and when the straw plug-in end is deflected to a required angle, the first electric The output end of the push-pull rod is extended to push the adapter block and the pawl, and the pawl is locked with the ratchet wheel to lock the deflection of the plug-in end of the straw, and then the rotating motor is powered on to start the rotating motor, and the output end of the rotating motor drives the screw rod to rotate, and the screw rod pushes the slider to move back and forth in the slide groove through the sliding cooperation with the slider. When the straw moves to the size range of organic fertilizer particles to be extracted, the second electric push-pull rod is powered on to start the second electric push-pull rod, and the output end of the second electric push-pull rod contracts and presses down the insertion tube, and the insertion tube presses down the plug-in end of the straw, so that the plug-in end of the straw is close to the inner wall of the disc to extract the organic fertilizer particles in the disc, so as to achieve the screening and adjustment of the size of the organic fertilizer particles. S4. Screening particles: When extracting particles, the organic fertilizer particles sucked up by the plug-in end of the straw enter the material box from the other end of the straw, and at the same time the vibrator is powered on and started, the vibrator drives the sieve plate to vibrate, and the sieve plate vibrates and screens the organic fertilizer particles, screening out the broken and loose organic fertilizer particles, so that the broken and loose organic fertilizer particles fall into the disc from one end of the bottom of the material box, while the remaining complete particles and stable organic fertilizer particles are discharged from the other end of the bottom of the material box, thereby realizing the screening of the organic fertilizer particles.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In this solution, when it is necessary to screen the organic fertilizer particles in the disc, the organic fertilizer particles extracted by the negative pressure pump through the straw are poured into the material box, and the vibrator is powered on to start the vibrator. The vibrator drives the sieve plate to vibrate, and the sieve plate screens the organic fertilizer particles and the broken and loose organic fertilizers, so that the broken and loose organic fertilizer particles are screened out from the small holes on the sieve plate, fall into one end of the bottom of the material box, and then fall into the disc, while the remaining complete particles and stable organic fertilizer particles are discharged from the other end of the bottom of the material box, thereby realizing the screening of organic fertilizer particles, effectively reducing the breakage of organic fertilizer particles, and then improving the quality of organic fertilizer particles.

[0018] 2. In the present scheme, when it is necessary to deflect the straw connecting end, the second motor is powered on and started, and the output end of the second motor drives the second driving gear to rotate, and the second driving gear drives the second driven gear to rotate by meshing with the second driven gear, and the second driven gear drives the second shaft rod to rotate, and the second shaft rod drives the deflection rod to deflect unidirectionally, and then drives the push-pull component, the lifting component and the straw connecting end to deflect unidirectionally. When the straw connecting end is deflected to the limit deflection angle, the output end of the second motor is reversed, and then the straw connecting end is reversely deflected to another deflection limit, and then the output end of the second motor is forwardly rotated again, so that the straw connecting end reciprocates in the disc, so that the straw connecting end can move to above the uniformly stacked organic fertilizer particles, which is convenient for negative pressure extraction of uniformly sized organic fertilizer particles, so that the fertilizer preparation device can effectively improve the uniformity of organic fertilizer particle specifications.

[0019] 3. In the present scheme, during the deflection of the straw connecting end, the output end of the first electric push-pull rod contracts and pulls the adapter block, and the adapter block pulls the pawl away from the ratchet to release the locking engagement between the pawl and the ratchet, so that the ratchet and the second shaft can rotate normally. When it is necessary to lock the deflection of the straw connecting end, the output end of the first electric push-pull rod extends to push the adapter block, and the adapter block pushes the pawl to engage with the ratchet, thereby limiting the deflection of the deflection rod and the straw connecting end and avoiding the deflection of the straw connecting end, thereby facilitating the rapid extraction of organic fertilizer particles of uniform size. By locking the deflection angle of the straw connecting end, the straw connecting end can accurately extract the key accumulation area of ​​the organic fertilizer particles, thereby realizing that the fertilizer preparation device can quickly separate the organic fertilizer particles and avoid the extrusion and agglomeration of the organic fertilizer particles.

[0020] 4. In this solution, when it is necessary to move the straw connecting end in a straight line from the center to the edge, the rotating motor is powered on to start the rotating motor, and the output end of the rotating motor drives the screw rod to rotate. The screw rod pushes the slider to move back and forth in the slide groove through the sliding cooperation with the slider, and the slider drives the second electric push-pull rod and the inserting tube to move in a straight line in the disc, so that the straw connecting end can extract organic fertilizer particles of different particle diameters from small to large according to the required diameter size, thereby realizing the selection of organic fertilizer particles of different particle sizes, so that the fertilizer preparation device can meet the needs of organic fertilizer preparation of particles of different diameters, and expand the production capacity of the fertilizer preparation device for organic fertilizer particles of different diameters.

[0021] 5. In this solution, the guide groove is used to accommodate the sliding of the guide block. The guide block limits the deflection limit range of the deflection rod and the straw plug-in end by sliding cooperation with the guide groove, thereby ensuring that the straw plug-in end will not suck in too much powdered organic fertilizer that has not been granulated, reducing the screening amount of the screening mechanism, and effectively improving the granulation efficiency of the fertilizer preparation device.
