The second chain 41 is mounted on a second sprocket wheel, which is driven by the driving motor to rotate, and drives the second chain 41 to rotate circularly, so that the second carrying claw 42 on the second chain 41 moves upward along the tilting lever 31 under the tilting lever 31. As shown in fig. 1-2, the inclined slope 11 and the inclined rod 31 are spaced apart from each other to form an inclined upward carrying passage P (carrying passage for carrying straw, as shown in fig. 2), and the inclined slope 11 and the lower end of the inclined rod 31 form an inlet for straw (inlet for picking up straw).

As shown in fig. 1, the first carrying claw 22 is fixed to the first chain 21 in a perpendicular manner to the first chain 21, and the second carrying claw 42 is fixed to the second chain 42 in a perpendicular manner to the second chain 41. As shown in fig. 2, it is preferable that the first carrying projection 22 is bent to form a hook shape toward a lower end of the carrying passage P, and the second carrying projection 42 is bent to form a hook shape toward an upper end of the carrying passage P.

By the shifting action of the shifting arm 62, the straws conveyed to the upper end of the inclined slope 11 by the carrying channel P are shifted to the horizontal table 12, and then shifted and pushed to the straw briquetting machine at the rear side.

Preferably, the width of the inclined slope surface 11 is 1-2 m, and a steel plate is preferably installed on the inclined slope surface 11 to more stably pick up various straws (such as corn straws, sorghum straws, wheat straws and millet straws) with different lengths, and the steel plate does not influence the operation of the lower chain assembly. When different types of straws are picked up, the distance between the inclined rod 31 and the inclined slope surface 11 can be adjusted, for example, the distance can be adjusted to be smaller when thinner wheat straws are picked up, and the distance can be adjusted to be larger when corn straws are picked up. The method for adjusting the distance is mainly realized by adjusting the upper end of the inclined rod to be fixed at different positions on the main frame.
