[0002] Organic fertilizer is mainly derived from plants or animals, applied to the soil to provide plant nutrition as its main function of carbon-containing materials. It is processed from biological substances, animal and plant waste, plant residues, which eliminates toxic and harmful substances and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides and rich nutrients including nitrogen, phosphorus and potassium. Not only can it provide comprehensive nutrition for crops, but also has long-term effect, can increase and update soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of the soil, and is the main nutrient for green food production.

[0003] Among them, plant straw is the main raw material of organic fertilizer, and when preparing organic fertilizer by composting and fermenting the straw, the straw needs to be crushed to ensure the fermentation effect. However, the existing organic fertilizer production method cannot shear the straw into different lengths according to different types of straw when processing the straw, affecting the fermentation effect.

[0053] like Figure 2 Example 2 of the method for preparing organic fertilizer is shown below:

[0054] A method for preparing organic fertilizer includes the following steps:

[0055] Step 1: Use a cutting device to cut different types of straw into segments of different lengths;

[0056] Step 2: Mix the chopped straw with corn flour, pig manure and distiller's grains to obtain mixture A;

[0062] The corn stalks and sorghum stalks are cut into segments of 2 cm in length, and the rice stalks are cut into segments of 4 cm in length.

[0063] The pig manure contains 40%-60% pig urine.

[0064] The fermentation agent is lactic acid bacteria, Bacillus, yeast, filamentous fungi, and Rhodospirillum.

[0066] When building up the fermentation pile, the initial temperature should be above 15℃.

[0068] Turn the compost pile when the fermentation temperature reaches 65℃.

[0069] The fermentation time is 10 days.

[0070] like Figures 3-10 The cutting device is described in detail below:

[0071] The cutting device includes a container 101, a semi-circular plate 102, a blocking plate 103, conveying rollers 104, a conveyor belt 106, rotating seats 201, cutters 202, and a drive shaft 203. A semi-circular plate 102 is fixed to one side of the container 101, and a blocking plate 103 is fixed to the outer end of the semi-circular plate 102. Two rotating seats 201 rotate symmetrically on the semi-circular plate 102, and two cutters 202 are fixed between the two rotating seats 201. The drive shaft 203 rotates laterally through the container 101 and is connected to the two rotating seats 201. Two conveying rollers 104 rotate on the side of the container 101 where the semi-circular plate 102 is fixed, and a conveyor belt 106 is sleeved on the two conveying rollers 104.

[0072] During the cutting process, the straw is placed on the conveyor belt 106 along the direction of the conveyor belt 106. The first motor installed on the container 101 is started to drive one of the conveyor rollers 104, so that the conveyor belt 106 drives the straw to move towards the semi-circular plate 102. At the same time, the second motor installed on the container 101 is started to drive the drive shaft 203, so that the drive shaft 203 drives the two rotating ring seats 201 to drive the two cutters 202 to rotate on the semi-circular plate 102. Thus, when the straw moves to the semi-circular plate 102, the rotating cutter 202 cooperates with the edge of the semi-circular plate 102 to cut the straw. With the continuous movement of the straw and the continuous rotation of the cutter 202, the straw is continuously cut into segments. The segments of straw fall into the semi-circular plate 102 and then slide into the container 101.

[0073] The inner sides of both rotating ring seats 201 are provided with conical surfaces, which can guide the straw into the space between the two rotating ring seats 201 to complete the cutting.

[0074] The cutting device further includes a blade ring 301, auxiliary blades 302, a connecting plate 303, a pin 304, and a positioning bolt 204. Two auxiliary blades 302 are fixed on the blade ring 301, and both auxiliary blades 302 slide inside the two blade rings 301, so that the two cutting blades 202 and the two auxiliary blades 302 are evenly distributed. The connecting plate 303 rotates on the blade ring 301, and the pin 304 rotates on the connecting plate 303. The pin 304 slides inside the drive shaft 203, and the positioning bolt 204 is threadedly connected to the drive shaft 203 and presses against the pin 304.

[0075] When the type of straw is changed and it is necessary to cut the straw into smaller sizes, the insert post 304 is pushed into the drive shaft 203, and the positioning bolt 204 is tightened on the insert post 304 to fix the insert post 304 and the drive shaft 203. When the insert post 304 slides into the drive shaft 203, the insert post 304 will drive the blade ring 301 to move closer to the blocking plate 103 through the connecting plate 303. Then, the two auxiliary blades 302 are inserted into the two rotating ring seats 201, so that the two rotating ring seats 201 rotate once and drive the four cutting blades to rotate once. Thus, while the straw supply speed remains unchanged, the cut straw segments are half the size of the original, thereby achieving the purpose of cutting the straw into smaller sizes.

[0076] Among them, two cutting blades 202 and two auxiliary blades 302 are distributed at intervals.

[0077] The cutting device also includes a fixed plate 105, a clamping frame 401, a clamping roller 402, a clamping belt 403, and a spring 404; two fixed plates 105 are fixed to the side of the container 101, the clamping frame 401 slides through the two fixed plates 105, two clamping rollers 402 rotate on the clamping frame 401, and a clamping belt 403 is sleeved on the two clamping rollers 402. A spring 404 is provided between the clamping frame 401 and the two fixed plates 105 so that the clamping belt 403 presses downward against the conveyor belt 106.

[0078] When conveying straw, the straw is first placed on the conveyor belt 106. As the conveyor belt 106 rotates, the straw will enter between the clamping belt 403 and the conveyor belt 106. The straw is clamped by the elastic force of the spring 404 on the clamping belt 403, thereby ensuring that the straw moves synchronously with the conveyor belt 106, and thus ensuring the feeding of the straw.

[0079] The side plates on both sides of the clamping frame 401 form a barrier between the clamping belt 403 and the conveyor belt 106, preventing straw from falling between the clamping belt 403 and the conveyor belt 106.

[0080] The cutting device further includes an inclined plate 107, a semi-circular plate 501, an insert plate 502, and a connecting crank 503. The inclined plate 107 is fixedly inclined inside the semi-circular plate 102. Multiple insert plates 502 slide through the inclined plate 107 and the blocking plate 103. The outer ends of the multiple insert plates 502 are fixed with the semi-circular plate 501. One end of the connecting crank 503 is fixed on the semi-circular plate 501, and the other end of the connecting crank 503 slides on the drive shaft 203. The connecting crank 503 is slidably connected through the inclined plate 107 and the blocking plate 103.

[0081] The inclined plate 107 is designed to facilitate the sliding of straw segments from the semi-circular plate 102 into the container 101. The drive shaft 203 has a reciprocating groove, which enables the reciprocating transmission to drive the crank 503 to move back and forth. This, in turn, drives multiple insert plates 502 to move back and forth and insert into the inclined plate 107 and the blocking plate 103 via the semi-circular plate 501. When the multiple insert plates 502 are inserted out of the inclined plate 107, they will push the straw segments on the inclined plate 107 into the container 101, thereby improving the efficiency of the straw segments sliding from the semi-circular plate 102 into the container 101 and preventing the presence of too many straw segments in the semi-circular plate 102, which would affect subsequent cutting.
