Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to an organic fertilizer raw material crushing device. Background Art

[0002] Organic fertilizer, also known as farmyard manure, is any fertilizer made from organic matter (compounds containing carbon). This includes human feces, manure, compost, green manure, cake fertilizer, and biogas fertilizer. Organic fertilizers are diverse, widely available, and have a long-lasting effect. Most of the nutrients in organic fertilizers are in an organic state, making them difficult for crops to directly utilize. Microorganisms slowly release a variety of nutrients, continuously supplying them to crops. The most commonly used raw material for organic fertilizer fermentation is straw, which needs to be pulverized in a grinder before fermentation.

[0003] When using existing crushing devices, the entire straw is put into the device, and the crushing cutter in the device crushes the straw. The crushing can only be performed once, and the single crushing effect is not good. Therefore, the crushing device is generally equipped with a screen at the bottom to separate and discharge the crushed straw with and without particle size standards. The crushed straw with particle size standards that does not meet the standards is then collected and crushed again. This results in a relatively long time to use the device. Therefore, in order to address the above shortcomings, the present invention proposes an organic fertilizer raw material crushing device. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an organic fertilizer raw material crushing device.

[0009] Furthermore, the transmission assembly includes a driving pulley fixed to the surface of the driving shaft and a driven pulley fixed to the surface of the transverse shaft, and a belt is sleeved on the upper surfaces of the driving pulley and the driven pulley.

[0010] Furthermore, the second crushing assembly includes a protective sleeve fixed to the top wall of the crushing barrel, the bottom wall of the protective sleeve passes through and is rotatably connected to a vertical shaft through a bearing, a plurality of second cutters are fixed to the bottom end of the vertical shaft, and a driven bevel gear is fixedly connected to the top end of the vertical shaft.

[0012] Beneficial effects of the utility model:

[0013] 1. When the utility model is in use, the organic fertilizer raw material crushing device is provided with a crushing cylinder, a trumpet bucket, a discharge pipe, a feed pipe, a first crushing assembly, a second crushing assembly and a screening assembly. When raw materials such as straw enter from the feed pipe, the straw is first cut off by the first crushing assembly, which is conducive to further crushing the cut straw by the second crushing assembly, thereby improving the crushing efficiency. In addition, the second cutter of the second crushing assembly is located on the screen surface of the screening assembly. Particles with a standard size will pass through the screen and fall, while particles with a size that does not meet the standard will be crushed by the second crushing assembly on the screen surface. Therefore, the step of collecting waste materials and re-feeding is omitted, and it is more convenient and saves trouble to use.
