[0002] With the development of biomass power generation and straw combustion power generation, energy conservation, environmental protection, and the development of new energy sources are all current research topics. In rural areas, harvested straw is typically baled into 1.2m x 1.2m x 1.2m square bales for easy transportation before being transported to factories for further processing. However, these bales are prone to internal heat and moisture absorption, affecting the rate of decomposition and gasification to produce biomass. Pre-drying increases the workload, resulting in the lack of a suitable decomposition device for bales of straw. Summary of the Invention

[0003] The purpose of this invention is to provide a biomass whole-bundle straw decomposition and gasification device to solve the problem that existing whole-bundle straw is easily affected by internal heat and moisture, which affects the rate of decomposition and gasification to produce biomass, and that pre-drying increases the number of work steps, resulting in the lack of a reasonable decomposition device for whole-bundle straw.

A transmission assembly is provided at the end of the moving rod extending to the outer side of the outer shell, and the transmission assembly is connected to the lower gear roller and the upper gear roller for transmission.

[0006] Preferably, the transmission assembly includes a rotating frame movably connected to one side of the housing. The rotation connection point of the rotating frame is located at one-third of the central axis of the rotating frame. A metal wire is fixedly connected between one end of the moving rod extending out of the outer side of the housing and the end of the rotating frame near the rotation connection point. A guide and limiting assembly is provided on the path of the metal wire.

[0007] Preferably, the guide limiting assembly includes a guide ring fixed to one side of the housing, the metal wire is wound around the guide ring and then fixedly connected to the rotating frame, a limiting frame is provided on one side of the guide ring, and the metal wire passes through the limiting frame for limiting.

[0008] Preferably, the transmission assembly includes a second gear movably connected to the front side of the housing, the second gear meshing with the rotating frame, the second gear being driven by an adjustment assembly via a timing belt, the adjustment assembly being driven by a rotating shaft via a timing belt, the rotating shaft being synchronously connected to multiple other rotating shafts via a timing belt, and the multiple rotating shafts respectively penetrating the housing and being fixedly connected to a lower gear roller and an upper gear roller.

[0009] Preferably, the second synchronous belt is also connected to a movable pulley, and a movable block is fixedly connected to one side of the movable pulley. The movable block is slidably connected to the mounting groove opened on the side of the housing. A telescopic rod is fixedly provided at the bottom of the movable block, and a spring is sleeved on the outside of the telescopic rod to form a tensioning purpose.

[0010] Preferably, the adjustment assembly includes a second rotating frame that is connected to the first synchronous belt for transmission. A pulley is sleeved on the outer side of the rotating shaft on the surface of the second rotating frame and moves synchronously with the first synchronous belt through the pulley. The pulley is made of an electromagnet that attracts the rotating shaft on the surface of the rotating frame when energized to form a synchronous drive. A threaded disc is movably connected to the inner side of the second rotating frame. An electromagnet ring is provided on the outer edge of the threaded disc and attracts the rotating frame when energized to form a relatively fixed connection and when de-energized to form a movable connection.

[0011] Preferably, a fixed plate is fixed on the other side surface of the rotating frame two. The fixed plate has several sliding grooves.

[0014] The technical effects and advantages of this invention are as follows: By connecting the crushing blade assembly and the positioning cylinder with a spring, the crushing blade assembly moves under pressure. Using a displacement sensor, initial and pressure displacement values ​​are preset. When these values ​​are reached, the electromagnet and electromagnet ring are energized and reversed periodically, changing from energized to de-energized within a short time interval (seconds). This energizes the gear and threaded disc, creating a driving force, while de-energizing the threaded disc and rotating frame creates a movable connection. In this state, if the crushing blade assembly presses against the spring and moves the moving rod, the moving rod will pull the metal... The pull wire drives the rotating frame to rotate, causing multiple arc-shaped parts connected to the threaded surface of the threaded disc to expand. This, in turn, drives the synchronous belt to pull the moving pulley downward, thereby changing the transmission ratio between the adjustment component and the rotating shaft. After 30 seconds, the electromagnet is de-energized, the electromagnet ring is re-energized, and the motor starts, driving the entire rotating shaft to rotate again, resuming the conveying of the whole bundle of straw. However, the conveying speed will be reduced compared to before the adjustment to accommodate the crushing of the damp and tough straw. The entire process can achieve adaptive adjustment without manual intervention, achieving maximum efficiency in the decomposition of whole bundles of straw. Attached Figure Description

The pulley is made of an electromagnet. When the electromagnet is energized, it attracts the rotating shaft on the surface of the rotating frame 2 to form a synchronous drive. A threaded disc is movably connected to the inner side of the rotating frame 2. An electromagnet ring is provided on the outer edge of the threaded disc and attracts the rotating frame 2 when energized to form a relatively fixed connection. When the electromagnet is de-energized, it forms a movable connection.

[0036] Specifically, a fixed plate 144 is fixed on the other side surface of the rotating frame 2. Several grooves 142 are provided on the fixed plate 144. Threaded blocks 145 are slidably connected inside the grooves 142. The threaded blocks 145 expand and close due to the rotation of the threaded plate. Arc-shaped parts 143 are fixedly connected to each of the multiple threaded blocks 145. Synchronous belt 2 13 is sleeved on the outer side of the multiple arc-shaped parts 143.

[0037] Specifically, the outer side of the rotating frame 2 is movably connected to the mounting bracket 141 via a bearing and is fixed to the outer side of the outer shell 3 via the mounting bracket 141. Gears are machined on the outer side of the rotating frame 2, and the rotating frame 2 is connected to a gear 146 via gear meshing. A motor 147 is driven and connected to the gear 146.

[0038] Specifically, the outer casing 3 is located at the top of the combustion device 1 and is equipped with a flue gas output device 4. The sleeve 204 is equipped with a displacement sensor and is electrically connected to an electromagnet and an electromagnet ring.

[0039] Working Principle: When using this invention, a whole bundle of straw is placed inside the outer casing 3 through the door panel 5. After the bundle of straw is placed inside and closed, the motor 147 is started, driving gear 146 to rotate. Gear 146 then drives the entire rotating frame 2 to rotate. At this time, the electromagnet is de-energized, while the electromagnet ring on the outer edge of the threaded disc is energized. This causes the rotating frame 2 to rotate, driving the threaded disc and multiple arc-shaped components 143 to rotate, without affecting the state of the timing belt 15. Multiple arc-shaped components 143 and timing belt 13 drive a rotating shaft 12 to rotate, and timing belt 11 drives multiple rotating shafts 12 to rotate, ultimately driving multiple lower gear rollers 6 and upper gear rollers 10. The rotating lower gear roller 6 and upper gear roller 10 compress and convey the entire bundle of straw until it reaches the vicinity of the crushing blade assembly 203 for crushing. The crushing blade assembly 203 is a crushing device with its own motor. This technology is existing and will not be described in detail. When encountering damp bundles of straw, the straw retains its toughness, affecting the crushing of the crushing blade assembly 203. This causes the straw conveyed by the lower gear roller 6 and upper gear roller 10 to compress the crushing blade assembly 203, affecting both the crushing and the operation of the crushing blade assembly 203. At this time, the crushing blade assembly 203 is connected to the positioning cylinder 205 by a spring 202, which allows the crushing blade assembly 203 to move when compressed. The displacement sensor is pre-set with initial and compressive displacement values. When these values ​​are reached, the electromagnet and electromagnet ring are energized and reversed periodically, changing from energized to de-energized and vice versa within 30 seconds. This energizes gear 16 and the threaded disc, creating a driving connection, while de-energizing the threaded disc and the rotating frame 2 creates a movable connection. In this state, if the crushing blade assembly 203 presses the spring 202 and moves the moving rod 201, the moving rod 201 will pull the metal wire 8, causing the rotating frame 7 to rotate. The rotation of the rotating frame 7 will then drive gear 16, which in turn drives the timing belt 15, ultimately rotating the threaded disc. This creates a connection between the threaded disc and the rotating frame 2. In the active connection state, the multiple arc-shaped parts 143 connected to the threaded surface of the threaded disc expand, thereby driving the synchronous belt 13 to pull the moving pulley 22 downward, thus changing the transmission ratio between the adjustment component 14 and the rotating shaft 12. After 30 seconds, the time depends on the situation and can be freely changed by the engineer, the electromagnet is de-energized and the electromagnet ring is re-energized. At the same time, the motor 147 starts and drives the entire rotating shaft 12 to rotate again, and resumes the conveying of the whole bundle of straw. However, the conveying speed will be reduced compared to before the adjustment to accommodate the crushing of damp and tough straw. The whole process can achieve adaptive adjustment and does not require manual intervention, achieving maximum efficiency in the decomposition of whole bundles of straw.
