The metal wire is wound around the guiding ring and then fixedly connected to the rotating frame. A limiting frame is arranged on one side of the guiding ring, and the metal wire passes through the limiting frame for limiting.

[0007] Preferably, the transmission assembly includes a second gear movably connected to the front side of the housing. The second gear is meshed with the rotating frame. The second gear is drivingly connected to an adjusting assembly through a first synchronous belt. The adjusting assembly is drivingly connected to one of the rotating shafts through a second synchronous belt. One of the rotating shafts is synchronously connected to a plurality of other rotating shafts through a third synchronous belt. The plurality of rotating shafts respectively penetrate the housing and are fixedly connected to a lower gear-type roller and an upper gear-type roller.

[0008] Preferably, a moving pulley is also drivingly connected to the second synchronous belt. A moving block is fixedly connected to one side of the moving pulley. The moving block is slidably connected to the inside of an installation groove formed in the side surface of the housing. A telescopic rod is fixedly arranged at the bottom of the moving block, and a spring is sleeved outside the telescopic rod for the purpose of tensioning.

[0009] Preferably, the adjusting assembly includes a rotating frame drivingly connected to the first synchronous belt. A belt pulley is sleeved outside the rotating shaft on the surface of the rotating frame and synchronously moves with the first synchronous belt through the belt pulley. The belt pulley is made of an electromagnet and adsorbs the rotating shaft on the surface of the rotating frame to form synchronous driving.

When the values are reached, the energized states of the electromagnet and the electromagnet ring are reversed at regular intervals, that is, the power-on state changes to power-off state and the power-off state changes to power-on state within seconds. This makes the gear two and the threaded disk form a driving state due to power-on, and the threaded disk and the rotating frame form a movable connection state due to power-off. In this state, when the crushing blade group presses the second spring and drives the moving rod to move, the moving rod will pull the metal wire to drive the rotating frame to rotate, causing the multiple arc-shaped parts threadedly connected to the surface of the threaded disk to expand, thereby driving the second synchronous belt to pull the moving pulley downward, so as to change the transmission ratio between the adjusting component and the rotating shaft. After 30 seconds, the power-off state of the electromagnet is restored, and the electromagnet ring is re-energized. At the same time, the first motor starts to drive the entire rotating shaft to rotate again, and the whole bundle of straw is conveyed again. However, the conveying speed at this time will be lower than that before adjustment to cooperate with the crushing of the straw with high toughness due to moisture. The whole process can achieve adaptive adjustment and does not require manual intervention, realizing the decomposition of the whole bundle of straw with the highest efficiency.

A gear is processed on the outer side of the rotating frame 148. The rotating frame 148 is connected to the gear 146 through gear meshing. The gear 146 is transmission-connected to the motor 147.

[0025] Specifically, the housing 3 is placed on the top area of the combustion device 1 and is provided with a smoke output device 4. A displacement sensor is provided inside the sleeve 204 and is electrically connected to the electromagnet and the electromagnet ring.

[0026] Working principle: When using the present invention, a whole bundle of straw is placed inside the outer shell 3 through the door panel 5. After the whole bundle of straw is put in and then the door is closed, the first motor 147 is started to drive the first gear 146 to rotate. The first gear 146 drives the entire rotating frame 148 to rotate. At this time, the electromagnet is in a power-off state, while the electromagnet ring on the outer edge of the threaded disc 149 is in a power-on state. This forms the rotation of the entire rotating frame 148 to drive the threaded disc 149 and multiple arc-shaped members 143 to rotate, but does not affect the state of the first synchronous belt 15. Multiple arc-shaped members 143 and the second synchronous belt 13 are used to drive a rotating shaft 12 to rotate, and the third synchronous belt 11 is used to drive multiple rotating shafts 12 to rotate, finally driving multiple lower gear-type rollers 6 and upper gear-type rollers 10 to rotate. The rotating lower gear-type rollers 6 and upper gear-type rollers 10 will conduct compressive transmission on the whole bundle of straw until it is transmitted to the vicinity of the crushing blade group 203 for crushing. The crushing blade group 203 is a crushing device with its own motor. This technology is prior art, so it will not be elaborated here. When encountering a whole bundle of straw that is damp, its toughness still exists, which affects the crushing of the crushing blade group 203, resulting in the straw conveyed by the lower gear-type rollers 6 and upper gear-type rollers 10 pressing on the crushing blade group 203, affecting the damage and also the operation of the crushing blade group 203. At this time, the crushing blade group 203 is connected to the positioning cylinder 205 through the second spring 202, so that the crushing blade group 203 will move when being pressed. A displacement sensor is used to preset the initial displacement and the pressing displacement values in advance. When the values are reached, the power-on states of the electromagnet and the electromagnet ring are periodically reversed, that is, the power-on state changes to power-off and the power-off state changes to power-on within 30 seconds. This causes the second gear 16 and the threaded disc 149 to form a driving state due to power-on, and the threaded disc 149 and the rotating frame 148 to form a movable connection state due to power-off. In this state, if the crushing blade group 203 presses the second spring 202 and drives the moving rod 201 to move, the moving rod 201 will pull the metal wire 8 to drive the rotating frame 7 to rotate. The rotation of the rotating frame 7 drives the second gear 16 to rotate, thereby driving the first synchronous belt 15 and finally driving the threaded disc 149 to rotate. Using the movable connection state formed between the threaded disc 149 and the rotating frame 148, multiple arc-shaped members 143 threadedly connected to the surface of the threaded disc 149 are expanded, thereby driving the second synchronous belt 13 to pull the moving pulley 22 downward, thus changing the transmission ratio between the adjusting assembly 14 and the rotating shaft 12. When 30 seconds (this time depends on the situation and can be freely changed by the engineer) has passed, the power-off state of the electromagnet is restored, the electromagnet ring is re-powered on, and at the same time, the first motor 147 is started to drive the entire rotating shaft 12 to rotate again, and the conveying of the whole bundle of straw is restarted. However, at this time, the conveying speed will be lower than before the adjustment to cooperate with the crushing of the damp and tough straw. The whole process can achieve adaptive adjustment and does not require manual intervention, realizing the decomposition of the whole bundle of straw with the highest efficiency.

[0027] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features.
