Description

Technical Field

[0001] The present invention relates to the field of feces fermentation, and in particular to an in-situ rapid composting fermentation device and method for livestock feces. Background Art

[0002] Livestock manure is a common manure source and has long been used as base fertilizer in agriculture. However, using unfermented livestock manure often causes problems such as seedling burn and insect infestation. Using livestock manure fermentation agents to fully ferment and compost livestock manure before using it in agriculture can effectively address these issues.

[0003] Livestock manure itself contains high levels of cellulose and hemicellulose, and has a high carbon content. Therefore, it is necessary to supplement raw materials and fully stir it during the fermentation process. Currently, it is mixed and stirred by stirring equipment. After each mixing, the staff needs to spend a long time cleaning the stirring equipment, which can easily cause discomfort. For this reason, we propose an in-situ rapid composting fermentation device and method for livestock manure. Summary of the Invention

[0014] Optionally, a ball bearing is provided on the side of the card plate away from the second spring piece to facilitate the left and right movement of the card plate.

[0015] The cam is fixed to the side panel that is located adjacent to the center of the cam, and the cam is secured to the side panel that is located adjacent to the center of the cam.

[0016] Optionally, a slot is provided on a side of the clamping plate away from the second spring piece, and the clamping plate can be limited or released by cooperating with a limiting rod.

[0017] Optionally, the surface of the fixing rod is provided with an annular locking tooth, and the clamping plate can be clamped in the annular locking tooth on the surface of the fixing rod to limit the winding shaft so that the winding shaft cannot rotate.

[0018] Optionally, the method for rapid in-situ composting and fermentation of livestock manure comprises the following steps:

[0019] Step 1: put the feces into the inside of the mixing tank, and add an appropriate amount of ammonium sulfate into the mixing tank. For fresh feces with high water content, straw powder, distiller's grains, furfural residue, etc. can be added to reduce the moisture content. Usually, the ratio of cow dung to these materials is 1:1 or 2:1. The specific amount added depends on the moisture content of the feces. The moisture content of the mixed material is %-%. The judgment standard is that when you grab a handful of it in water, there is water between your fingers but it does not drip;

[0020] Step 2: Turn on the motor, the motor drives the rotating rod to rotate clockwise, and the rotating rod drives the fixed rod to rotate clockwise together, so that the cleaning scraper cannot move, and the stirring blade rotates to fully stir the feces and materials inside the mixing tank;

[0022] Step 4. Pour clean water into the mixing tank, start the motor to reverse, and the motor drives the rotating rod to rotate counterclockwise. At this time, the fixed rod cannot rotate together. At this time, the card plate is stuck in the annular card teeth on the surface of the fixed rod, and the winding shaft cannot rotate. While the cleaning scraper rotates with the stirring blade, the pull rope is continuously wound around the winding shaft, and the cleaning scraper moves to the side close to the fixed rod. As the pull rope is continuously wound, the pull rope squeezes the arc-shaped iron sheet, causing the arc-shaped iron sheet to retract into the inside of the winding shaft with the push rod, and the push rod pushes the card plate against the bulge.
