[0002] The use of straw has a long history, but due to the low level of agricultural production in the past, the amount of straw was small. Except for a small amount of straw used as bedding, feeding livestock, and some used for composting, most of the straw was burned as fuel. With the development of agricultural production, grain output has increased significantly, and the amount of straw has also increased.

[0003] The patent with patent announcement number CN218851362U relates to a straw picker, including: a device body, including a vehicle head, a support plate fixedly connected to one side of the back of the vehicle head, a support frame connected to the top surface of the support plate, a control box connected to one side of the support plate, a connecting plate connected to one side of the control box, and a first collecting shovel fixedly connected to the top surface of the connecting plate; an adjustment structure is inserted inside the connecting plate, including a second collecting shovel, and a telescopic rod is fixedly connected to the bottom of the second collecting shovel. The patent moves the position of the limit plate after pressing the limit plate, so that the telescopic rod moves and the second collecting shovel moves in the slide groove opened in the connecting plate at the same time, and then the limit plate is released to allow the positioning block to be inserted into the card slot opened in the connecting plate, thereby realizing the function of adjusting the distance between the first collecting shovels, and avoiding the first collecting shovels from being too large to scoop up and recycle straws of different sizes.

[0004] In the above patent, by pressing the limit plate and then moving the position of the limit plate, the telescopic rod moves and the second collecting shovel moves in the slide groove opened in the connecting plate, and then the limit plate is released to allow the positioning block to be inserted into the slot opened in the connecting plate, thereby achieving the function of adjusting the distance between the first collecting shovels to avoid the first collecting shovels being too large to scoop up and recycle straw of different sizes. However, during the recycling process, the straw may be on both sides of the collecting shovel, causing the straw to be pushed away during recycling, affecting the recycling efficiency.
