[0002] Organic fertilizer is a type of fertilizer that mainly comes from plants and animals. It is a carbon-containing material applied to the soil with the main function of providing plant nutrition. It is processed from biomass, animal and plant waste, and plant residues, eliminating toxic and harmful substances. It is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil. It is the main nutrient for green food production. When processing and producing organic fertilizer, a crushing device is required to crush the raw materials.

[0004] The above scheme can selectively crush the fertilizer according to the required specifications, and can purify the dust when the fertilizer is crushed, but the following problems still exist in the fertilizer crushing process: (1. The crushing effect achieved by crushing only with crushing tools is not good, and the crushed fertilizers are of different sizes, which affects the processing quality of organic fertilizers; (2. If the feeding speed of organic fertilizer raw materials is too fast during the feeding process, it may cause the raw materials to pile up, so that the raw materials cannot be fully crushed. At the same time, it will also cause a load on the crushing device, resulting in increased wear of the device and shortening the service life of the device.

[0005] Therefore, the design is highly practical and the first rotating rod drives the second rotating rod to rotate under the transmission action of the first belt transmission assembly and the second belt transmission assembly, and the second rotating rod drives the rotating plate to rotate, so that the arc frame can drive the connecting rod to move back and forth laterally through the sliding block, and the connecting rod drives the pushing plate to push the raw materials in the discharge box intermittently and repeatedly under the guide limit of the limit seat, so that the pre-crushed raw materials can be discharged through the discharge port at a uniform speed, and an organic fertilizer processing and crushing device is very necessary to prevent blockage and equipment shutdown caused by excessive feeding.

The present invention starts the first motor to make the two rollers rotate towards each other, and the crushing blades on the rollers can pre-crush the bulk materials in the raw materials to ensure that the size of the raw materials before entering the crushing chamber is appropriate, thereby improving the crushing efficiency. When the crushing blades rotate, they will repeatedly pass through the cleaning grooves on the cleaning seat, so that the raw materials attached to or inserted on the crushing blades can be scraped off, and the pre-crushed raw materials enter the crushing chamber through the discharge box. The second motor is started to make the two crushing rollers rotate towards each other, so that the raw materials entering the crushing chamber can be further crushed, thereby improving the crushing effect.

In the present invention, the first rotating rod drives the second rotating rod to rotate under the transmission action of the first belt transmission assembly and the second belt transmission assembly, and the second rotating rod drives the rotating plate to rotate, so that the arc frame can drive the connecting rod to move back and forth laterally through the sliding block, and the connecting rod drives the pushing plate to push the raw materials in the discharge box intermittently and repeatedly under the guide limit of the limit seat, so that the pre-crushed raw materials can be discharged through the discharge port at a uniform speed, preventing blockage and equipment shutdown due to excessive feeding.

[0019] 3. In the present invention, when the crank connecting rod is driven to rotate by the second motor, the connecting plate can pull the wedge block to move vertically back and forth along the wedge-shaped slide rail through the fixed rod. When the wedge block moves, the fixed rod drives the slider to move up and down repeatedly through the connecting rod.

Fertilizers of qualified size will fall on the guide inclined plate through the sieve holes and be discharged through the discharge port. Unqualified fertilizers will enter the feed box through the conveying pipe under the inclination of the screen plate. The spiral feed rod is driven to rotate by the third motor, so that the unqualified fertilizers can be transported upward and poured back into the crushing box through the connecting pipe, so that the organic fertilizers that are not completely crushed can be crushed for the second time.

[0020] 4. The present invention can absorb the dust generated in the crushing box by starting the fan, and the partition net can block the solid matter in the dust. The dust cover can effectively prevent the dust from flying out and polluting the working environment. The dust net can protect the fan and prevent the outside dust from entering. When the fertilizer is screened, the dust suction pump is started, so that the dust generated by the screening is sucked into the dust suction pipe and blown to the guide inclined plate through the dust exhaust pipe to be discharged with the fertilizer. The blown wind can improve the guide fluidity of the guide inclined plate and improve the discharge efficiency of the organic fertilizer. BRIEF DESCRIPTION OF THE DRAWINGS
