Straw crushing device for straw drainage body production

Abstract

The invention provides a straw crushing device for straw drainage body production, which includes a frame, on which a feeder box arranged obliquely and a panel located in front of the feeder box are installed, and a feeding port is opened at the front part of the lower end of the feeder box , a motor is installed on the panel, a turntable and a cutter are installed on the output shaft of the motor, a backing plate is slidably connected to the panel, a tension spring is connected between the backing plate and the panel, and the pad A driving rod is connected to the plate, and a raised portion corresponding to the driving rod is provided on the turntable. Due to the adoption of the above-mentioned technical scheme, when the turntable rotates, the raised portion rotates with the turntable, and when the raised portion contacts the driving rod, the backing plate is pushed out. At this time, the front end of the straw is located above the backing plate, and the straw The front end of the straw is located on the material box. When the cutter cuts the straw, it avoids the bending of the front end of the straw, ensures the consistency of the cut length of the straw, and improves the cutting quality.

Description

technical field [0001] The invention relates to the technical field of straw processing equipment. Specifically, it relates to a straw crushing device for straw drainage body production. Background technique [0002] In the dredging of ports, waterways, lakes or rivers, a large amount of silt will be produced, and the commonly used large-area treatment method is to store it in a yard with cofferdams. This treatment method occupies a large amount of land resources, which will not only increase the project cost due to the high cost of land acquisition, but also cause huge social conflicts due to the high moisture content of the silt, which makes it difficult to recultivate the acquired land in a short period of time. The nature of the silt in the cofferdam is poor, which can easily cause landslide accidents. [0003] In order to speed up the consolidation speed of the silt and the turnover speed of the land, the method of vacuum preloading is generally used to treat the silt...

Problems solved by technology

In recent years, studies have shown that straw can be used as a drainage medium for engineering construction, but the length and uniformity of straw will affect its drainage rate under certain soil lateral pressure.
