Description

Technical Field

[0001] This utility model belongs to the field of straw crushing equipment, specifically relating to a corn straw crusher for oyster mushroom cultivation. Background Technology

[0002] In recent years, with the significant decrease in the number of herbivorous livestock such as cattle, horses, and donkeys, and the increasing efforts in prohibiting straw burning and protecting the environment, the comprehensive utilization of corn straw has become a social problem troubling governments at all levels and farmers. Returning straw to the field is also not widely promoted because the straw's failure to decompose quickly can lead to soil moisture and nutrient loss.

[0003] With the continuous expansion of edible fungi cultivation in recent years, the demand for raw materials for edible fungi cultivation has increased sharply. Cottonseed hulls, which are usually used as a culture medium, contain 5% crude protein; corn cobs contain only 2% crude protein; while corn stalks contain 5.8% crude protein and are inexpensive. Therefore, corn stalks are currently the most ideal culture medium for the cultivation of straw-decomposing edible fungi, as they are not only abundant in resources but also inexpensive.

[0004] Chinese utility model patent CN218789219U discloses a straw crusher that improves the working environment of straw crushing by adding a dust removal mechanism. However, the crusher does not take into account the addition of auxiliary materials while crushing the straw. Since corn stalks may contain miscellaneous bacteria and cannot provide enough nutrients for oyster mushrooms, it is necessary to add antibacterial agents and auxiliary materials after crushing the straw and mix them thoroughly. This makes the corn stalk processing process cumbersome and the oyster mushroom cultivation efficiency low.

[0005] Therefore, how to provide a corn stalk crusher for oyster mushroom cultivation that can simultaneously crush corn stalks and add auxiliary materials has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model discloses a corn stalk crusher for oyster mushroom cultivation. The spraying mechanism of this utility model can spray auxiliary materials while crushing the stalks, killing various pathogens and providing nutrients for the growth of oyster mushrooms, thereby improving the processing speed of corn stalks.

[0007] To achieve the above objectives, the present invention specifically discloses the following solution:

[0008] A corn stalk crusher for oyster mushroom cultivation includes a frame, a drive motor, a crushing mechanism, a feeding mechanism, and a spraying mechanism. The crushing mechanism and the feeding mechanism are connected and mounted on the frame. The feeding mechanism includes a feeding bin and a conveyor belt. The feeding bin is inclined, and the conveyor belt is located within the feeding bin. The drive motor is located at the bottom of the frame and is drive-connected to both the crushing mechanism and the conveyor belt. The spraying mechanism includes an atomizing nozzle, a sealing cover, a water pump, and a water tank. The top wall of the feeding bin has a through hole, and the sealing cover is installed in the through hole. The atomizing nozzle is installed within the sealing cover. The water pump and the water tank are located at the bottom of the frame, and the atomizing nozzle is connected to the water tank via the water pump.

[0009] Furthermore, the crushing mechanism includes a crushing box, a crushing roller, and a first pulley. The crushing box is fixed on the frame, and a feeding platform is provided above the crushing box. Bearing seats are provided on both sides of the frame of the crushing box, and bearings are installed in the bearing seats. The crushing roller is rotatably mounted in the crushing box, and a screening plate is provided below the crushing roller. The two ends of the main shaft of the crushing roller extend out of the crushing box and are inserted into the bearings. The first pulley is installed on the main shaft at one end of the crushing roller, and the first pulley is connected to the drive motor through belt drive.

[0010] Furthermore, the crushing roller includes a main shaft, a cutter disc, crushing blades, and a cutter shaft. The cutter discs are arranged on the main shaft, the cutter shafts are arranged around the edge of the cutter discs around the main shaft, the crushing blades are arranged on both sides of the cutter discs, and the crushing blades are rotatably mounted on the cutter shafts.

[0011] Furthermore, the drive shaft of the conveyor belt is fixedly connected to a second pulley, and the second pulley is connected to the drive wheel via belt drive.

[0012] Furthermore, it also includes a dustproof net, which is installed on the sealing cover below the atomizing nozzle to prevent debris from clogging the atomizing nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates a spraying mechanism on the feeding mechanism, which dissolves water-soluble additives such as quicklime, carbendazim, and urea in water within a water tank. These additives are then evenly sprayed onto the crushed straw through atomizing nozzles. This process sterilizes the crushed straw while providing excellent nutrients, eliminating the need for fermentation and facilitating rapid processing of corn straw. The addition of a crushing roller ensures uniform crushing of the corn straw. Attached Figure Description
