Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model provides a straw fermentation device through improvement, and the technical solution of the utility model is:

As shown in Figures 1-4, a straw fermentation device includes a fermentation box 1, a crushing box 2 is arranged on one end of the upper side of the fermentation box 1, and a water tank 3 is fixed on the bottom of the fermentation box 1, and one end of the crushing box 2 is installed There is a first motor 4, and also includes;

A crushing mechanism, the crushing mechanism is arranged inside the crushing box 2;

The pulverizing mechanism comprises two pulverizing rollers 5 that are rotatably connected to the inside of the pulverizing box 2 and a chute 6 that is opened at one end of the pulverizing box 2. One end of the two pulverizing rollers 5 is fixedly connected with a gear 7, and one of the pulverizing rollers The other end of 5 is fixedly connected with the output shaft of the first motor 4, and the two gears 7 are meshed through the teeth. The inside of the chute 6 is slidably connected with a sliding rod 8, and the bottom end of the sliding rod 8 is fixed with a transmission rod 9. The bottom of the bar 9 is provided with a cam 10 fixed on one end of one of the crushing rollers 5, the other end of the bottom of the slide bar 8 is fixed with a cutting knife 11, and a spring 12 is fixed between the lower side of the slide bar 8 and the chute 6, One side of the crushing box 2 is provided with a feed inlet 19, and the lower side of the feed inlet 19 is higher than the upper surfaces of the two crushing rollers 5.

Further, one end of the fermentation tank 1 is equipped with a second motor 13 and a water pump 14, and the inner upper side of the fermentation tank 1 is fixed with a spray pipe 16, the output shaft of the second motor 13 is fixed with a stirring blade 15, and the water inlet of the water pump 14 The end is communicated with the inside of the water tank 3 through a water pipe, and the water outlet end of the water pump 14 is communicated with the nozzle 16 through a water pipe, so that the straw can be humidified to ensure the humidity environment required for fermentation.

Further, a heater 17 is installed at the outer end of the water tank 3 to heat the water entering the water tank 3 inside the fermentation tank 1 to an appropriate temperature, so as to promote the sufficient reproduction of the fermentation bacteria and increase the fermentation speed.

Further, one side of the fermentation tank 1 is provided with a discharge port 18, and a valve is provided in the discharge port 18, so that the straw inside the fermentation tank 1 is discharged to the outside, and then used for operations such as fertilization.

Further, the lower end of the transmission rod 9 is rotatably connected with a roller 20, and the roller 20 is rollingly connected with the cam 10 to reduce the friction force generated when it contacts with the cam 10, so that the up and down reciprocating motion of the cutting knife 11 is more stable.
