[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0019] like Figure 1-5 As shown, the utility model provides a movable straw crushing device, including a body 1, a storage box 2, a feed platform 3, a feed box 4, a crushing roller 5, a feed pipe 6, and a feed fan 7 installed on the body 1; the feed platform 3 is docked at a feed port 8 arranged on the side wall of the feed box 4, and the crushing roller 5 is rotatably mounted on the inner wall of the feed port 8 through a bearing; the feed pipe 6 is installed on the top of the feed box 4, and the upper end of the feed pipe 6 is docked in the storage box 2; the feed fan 7 is installed in the feed box 4, and is located below the feed pipe 6; the crushing roller 5 and the feed fan 7 are connected to the power shaft 9 through transmission, and the power shaft 9 is installed on the body 1 and connected to the output shaft of the engine of the body 1 through a belt drive. The straw is placed on the feeding platform 3 to facilitate feeding the straw into the feeding port 8. The engine of the vehicle body 1 drives the power shaft 9 to rotate, thereby driving the crushing roller 5 and the feeding fan 7 to work. The crushing roller 5 rotates to cut and crush the straw fed into the feeding port 8; the feeding fan 7 is located below the feeding pipe 6, and blows air toward the feeding pipe 6, so that a strong airflow from the feeding port 8 to the feeding box 4 and then to the feeding pipe 6 is formed in the feeding box 4 and the feeding pipe 6, so that the crushed straw is driven by the airflow to be blown out from the upper end of the feeding pipe 6 into the storage box 2 for storage. The utility model crushes the straw through the crushing roller 5 installed on the vehicle body 1, and then conveys the straw to the storage box 2 through the feeding box 4 and the feeding pipe 6. The straw can be crushed and stored while moving in the field with the distribution of the straw, avoiding the need to collect the straw and then crush it, thereby improving the efficiency of straw crushing. At the same time, the power for straw crushing and conveying comes from the engine of the vehicle body 1, which has the effect of saving energy.

[0020] The feeding platform 3 is also provided with a conveyor belt 31, and the conveyor roller of the conveyor belt 31 is in driving connection with the power shaft 9. The power shaft 9 drives the conveyor roller to rotate, thereby driving the conveyor belt 31 to convey, and the straw is placed on the feeding platform 3, and under the action of the conveyor belt 31, the straw is automatically fed into the feed port 8, so that the straw is crushed by the crushing roller 5, thereby improving the feeding efficiency of the straw and saving manpower.

[0021] The feed platform 3 is rotatably mounted on the side wall of the feed port 8 of the feed box 4 through the conveying roller of the conveyor belt 31, and the feed platform 3 and the side wall of the feed port 8 are provided with a lock 32. The feed platform 3 can be rotated and flipped upward by rotating the conveying roller installed on the vehicle body 1, and then locked by the lock 32, so that the feed platform 3 does not affect the operation of the vehicle body 1 when the vehicle body 1 is started. When straw crushing is required, the feed platform 3 can be opened downward, which improves the practicality of the utility model.

[0022] The outer wall of the crushing roller 5 is evenly provided with crushing blades 51 in the circumferential direction, and the angle between the crushing blades 51 and the cut surface of the surface of the crushing roller 5 is less than 30 degrees. When the crushing blades 51 rotate with the crushing roller 5, the angle between the crushing blades 51 and the cut surface is small, so it is more convenient to chop the straw, and the straw crushing is more labor-saving, thereby improving the efficiency of the straw crushing.

[0023] The conveying box 4 is provided with an inclined surface 41 for facilitating the conveying of crushed straw, the lower end of the inclined surface 41 is installed at the bottom of the conveying box 4, and the upper end is flush with the upper end of the conveying fan 7. The setting of the inclined surface 41 can make the crushed straw enter the conveying pipe 6 from the conveying box 4 more smoothly, thereby improving the efficiency of straw conveying.

[0024] The power shaft 9 is connected to the conveying roller of the conveyor belt 31 through a bevel gear 91, and the power shaft 9 is connected to the crushing roller 5 through a transmission shaft I92. The transmission shaft I92 is installed on the vehicle body 1, and the power shaft 9 is connected to the transmission shaft I92 through gear transmission, and the transmission shaft is connected to the crushing roller 5 through a bevel gear 91. Since the power shaft 9 is connected to the engine of the vehicle body 1 through a belt drive, the power shaft 9 and the conveying roller of the conveyor belt 31 are perpendicular to each other in rotation direction, so it is necessary to use a bevel gear 91 to connect the two for transmission, so that the power shaft 9 drives the conveying roller to rotate, thereby driving the conveyor belt 31 to transport the straw; the power shaft 9 and the crushing roller 5 are perpendicular to each other in rotation direction, and are not in the same plane, so the power is transmitted to the transmission shaft I92 located in the same plane as the crushing roller 5 through gears, and then the power is transmitted to the crushing roller 5 through the bevel gear 91, thereby driving the crushing roller 5 to rotate to chop the straw.

[0025] The rotating shaft of the feeding fan 7 is connected to the power shaft 9 through a transmission shaft II 93, which is installed on the vehicle body 1, connected to the power shaft 9 through a gear, and connected to the rotating shaft of the feeding fan 7 through a bevel gear 91. Since the rotating shaft of the feeding fan 7 is perpendicular to the rotation direction of the power shaft 9 and is not in the same plane, the power is transmitted to the transmission shaft II 93 located in the same plane as the rotating shaft of the feeding fan 7 through the gear, and then the power is transmitted to the feeding fan 7 through the bevel gear 91, so that the feeding fan 7 rotates to form an airflow to transport the straw.

[0026] Working process:

[0027] The straw is placed on the feeding platform 3, and the feeding port 8 is automatically fed under the action of the conveyor belt 31, so that the straw is conveniently fed into the feeding port 8. The engine of the vehicle body 1 drives the power shaft 9 to rotate, thereby driving the crushing roller 5 and the feeding fan 7 to work. The crushing roller 5 rotates to cut and crush the straw fed into the feeding port 8; the feeding fan 7 is located below the feeding pipe 6, and blows air toward the feeding pipe 6, so that a strong airflow from the feeding port 8 to the feeding box 4 and then to the feeding pipe 6 is formed in the feeding box 4 and the feeding pipe 6, so that the crushed straw is driven by the airflow to be blown out from the upper end of the feeding pipe 6 into the storage box 2 for storage. The utility model crushes the straw through the crushing roller 5 installed on the vehicle body 1, and then conveys the straw to the storage box 2 through the feeding box 4 and the feeding pipe 6. The straw can be crushed and stored while moving in the field with the distribution of the straw, avoiding the need to collect the straw and then crush it, thereby improving the efficiency of straw crushing.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
