Description

Technical Field

[0001] The utility model belongs to the technical field of straw fermentation tanks, and particularly relates to a stirring structure and a stirring device for a straw fermentation tank. Background Art

[0002] Straw fermentation is a treatment method to improve the nutritional value of straw. By ammoniating, alkalizing, silaging and other treatments of straw, the feed resources can be reasonably developed to solve the problems of forage and feed. And the straw fermentation tank is a facility specifically used for treating agricultural straw and converting it into useful products;

[0003] When the existing stirring device of the straw fermentation tank is in use, it usually adopts a stirring shaft and blades driven by an electric motor. Through the stirring paddle, it rotates in the fermentation tank to stir the materials, achieving the effect of turning up and down and lateral diffusion. However, since the straw is stacked in the fermentation tank, when stirring at this time, the stirring paddle is difficult to enter the straw fermentation pile, resulting in limited stirring effect, so that the agglomerated straw in the fermentation tank cannot be well dispersed. At the same time, it also correspondingly increases the required stirring time of the straw fermentation tank. There is also a way to place the stirring paddle inside the fermentation tank, but in this way, as the straw ferments, the stirring mechanism is easily corroded, resulting in a reduced service life. Summary of the Utility Model

[0004] In view of this, the utility model provides a stirring structure and a stirring device for a straw fermentation tank. Through the stirring mechanism, the straw fermentation tank can be turned up more conveniently, making it easier for the stirring mechanism to enter the straw fermentation tank. While effectively improving the stirring effect, it can also disperse the agglomerated straw in the fermentation tank, reduce the required stirring time of the straw fermentation tank, and extend the service life of the stirring device of the straw fermentation tank.

[0005] To solve the above technical problems, the utility model provides a stirring structure and a stirring device for a straw fermentation tank, including a U-shaped frame and a stirring mechanism arranged at the lower end of the U-shaped frame. The stirring mechanism includes circular plates respectively rotatably connected to the lower ends of the left and right wall surfaces of the U-shaped frame. An annularly and evenly distributed turning plate is arranged at the edge between the two circular plates. A driving component for driving the rotation of the circular plate on the right side is also arranged at the right end of the U-shaped frame.

[0006] The stirring mechanism further includes a dispersing frame annularly and evenly rotatably connected to the middle between the two circular plates.

[0007] The upper surface of the U-shaped frame is provided with laterally symmetrically distributed electric telescopic rods, and the electric telescopic rods are all electrically connected to an external single-chip microcomputer; it also includes a walking gantry. Installation ports corresponding to the electric telescopic rods one by one are arranged at the upper left and right ends of the walking gantry, and the walking gantry is electrically connected to an external single-chip microcomputer.

[0008] The driving component includes an assembly groove arranged at the right end of the v-shaped frame, and the right side of the circular plate located at the right end of the v-shaped frame extends into the assembly groove. A motor is provided at the right end of the upper surface of the v-shaped frame, and a pulley 1 is provided at the right end of the output shaft of the motor. A pulley 2 is provided at the right end of the outer arc surface of the circular plate. Pulley 2 is connected to pulley 1 through a transmission belt transmission, and the motor is electrically connected to an external single-chip computer. A transmission component for driving the dismantling frame is also provided at the lower end of the assembly groove.

[0009] A protective shell is arranged on the right side of the upper surface of the shaped frame, and the motor and the pulley are both located in the protective shell.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0021] As Figure 1-4 shown:

[0022] This embodiment provides a stirring structure and a stirring device for a straw fermentation tank, including a U-shaped frame 300 and a stirring mechanism arranged at the lower end of the U-shaped frame 300. The stirring mechanism includes circular plates 400 respectively rotatably connected to the lower ends of the left and right wall surfaces of the U-shaped frame 300. At the edge between the two circular plates 400, throwing and turning plates 401 are evenly distributed in a ring shape. At the right end of the U-shaped frame 300, a driving assembly is further provided for driving the circular plate 400 on the right side to rotate; the stirring mechanism further includes a dispersing frame 402 rotatably and evenly connected in a ring shape in the middle between the two circular plates 400.

[0023] As Figure 1-4 shown, the driving assembly includes an assembly groove 500 arranged at the right end of the U-shaped frame 300. The right side of the circular plate 400 located at the right end of the U-shaped frame 300 extends into the assembly groove 500. At the right end of the upper surface of the U-shaped frame 300, a motor 501 is provided. At the right end of the output shaft of the motor 501, a pulley one 502 is provided. At the right end of the outer arc surface of the circular plate 400, a pulley two 503 is provided. The pulley two 503 and the pulley one 502 are connected by a conveyor belt 504 for transmission. The motor 501 is electrically connected to an external single-chip microcomputer. At the lower end of the assembly groove 500, a transmission assembly for driving the dispersing frame 402 is further provided.

[0024] As Figure 2-4 shown, the transmission assembly includes an installation cavity 600 provided in the middle of a circular plate 400 on the right side. At the lower end of the right wall surface of the assembly groove 500, there is a fixed rod 601. The left end of the fixed rod 601 passes through an opening provided on the right end face of the installation cavity 600 and a fixed gear 602 is provided at the end. The right ends of the dispersing frames 402 all extend into the installation cavity 600. Transmission gears 603 are provided at the extended ends on the right side of the dispersing frames 402. The transmission gears 603 are all meshed and connected with the fixed gear 602.

[0025] As Figure 1-2 shown, electric telescopic rods 200 are symmetrically distributed horizontally on the upper surface of the U-shaped frame 300. The electric telescopic rods 200 are all electrically connected to an external single-chip microcomputer; further included is a walking gantry 100. Installation ports corresponding to the electric telescopic rods 200 one by one are provided at the left and right ends on the upper side of the walking gantry 100. The walking gantry 100 is electrically connected to an external single-chip microcomputer.

[0026] The working principle of the stirring structure provided by the present utility model and the stirring device of the straw fermentation tank is as follows: First, relevant staff place the walking gantry 100 and its affiliated mechanisms above the straw fermentation tank. Then, relevant staff regulate the synchronous operation of the walking gantry 100, the electric telescopic rods 200, and the motor 501 through an external single-chip microcomputer. The walking gantry 100 and its affiliated mechanisms move uniformly along the straw fermentation tank, so as to be able to stir the straw fermentation tank more comprehensively. The reciprocating movement of the telescopic ends of the electric telescopic rods 200 drives the U-shaped frame 300, the circular plate 400, the turning plate 401, the dispersing frames 402, the assembly groove 500, the motor 501, the first pulley 502, the second pulley 503, the conveyor belt 504, the installation cavity 600, the fixed rod 601, the fixed gear 602, and the transmission gears 603 to move reciprocally synchronously, thereby stirring the straw fermentation tank at different depths. And after the stirring is completed, the U-shaped frame 300 and its affiliated mechanisms can be lifted and taken out of the straw fermentation tank, so as to extend the service life of the stirring device of the straw fermentation tank. The rotation of the output shaft of the motor 501 drives the first pulley 502 to rotate synchronously. When the first pulley 502 rotates, it drives the second pulley 503, the circular plate 400, the turning plate 401, the dispersing frames 402, the installation cavity 600, and the transmission gears 603 to rotate synchronously through the conveyor belt 504, thereby preliminarily stirring the straw in the straw fermentation tank. The design of the turning plate 401 can turn up the straw fermentation tank more conveniently, so that the stirring mechanism can more easily enter the straw fermentation tank. At the same time, while the transmission gear 603 revolves, it is restricted by the fixed gear 602 to drive the dispersing frame 402 to rotate reversely, which can not only effectively improve the stirring effect but also disperse the agglomerated straw in the fermentation tank, reducing the required stirring time of the straw fermentation tank.

[0027] As Figure 1 As shown, a protective shell 700 is provided on the right side of the upper surface of the shaped frame 300 , and the protective shell 700 plays a role of safety protection for its internal mechanism. The motor 501 and the pulley 1 502 are both located in the protective shell 700 .

[0028] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
