[0011] In use, the straw is put into the feed end of the feed conveying mechanism, and moves to the feed chamber along with the conveying chain plate. The hot air fans in the hot air box below the feed chamber work to blow hot air in the direction of the conveying chain plate. The hot air enters the feed chamber through the air inlet holes on the conveying chain plate, heats the straw and accelerates the air flow on the surface of the straw, thereby drying the straw entering the feed chamber. The dried straw moves to the discharge end along with the conveying chain plate, and then falls into the crushing chamber below. The crushing rollers in the crushing chamber rotate to crush the straw. The crushed straw material falls into the discharge conveying mechanism from the discharge port at the bottom of the crushing chamber, and is then conveyed to the storage bin by the elevator for storage.

[0012] According to one specific embodiment, a flow guide is further connected between the hot air machine and the hot air chamber.

[0013] Further, the flow guide comprises a mounting plate fixedly connected with the hot air chamber and a flow guide fin extending into the hot air chamber.

[0014] Still further, the flow guide fin is obliquely arranged towards the direction of the conveying chain plate and is arranged in multiple pieces along the height direction of the hot air chamber.

[0015] According to one specific embodiment, the crushing mechanism comprises a gear transmission mechanism and crushing rollers. The transmission mechanism adopts gear transmission, and the two crushing rollers are driven to rotate reversely by the gear transmission mechanism, so as to be engaged with each other and crush the straw by the crushing blades thereon.

[0016] According to one specific embodiment, the bottom of the crushing chamber is conical in structure, which reduces the accumulation and blockage of the material in the crushing chamber and the discharge port, and the discharge port is connected with a discharge conveying mechanism below. The discharge conveying mechanism and the material are connected by a material lifting machine to convey the crushed material to a storage bin.

[0017] According to one specific embodiment, the discharge conveying mechanism adopts a spiral conveyor.

[0018] The beneficial effects of the present application are as follows:

[0019] The present application can dry the straw in the conveying process, thereby avoiding the problem that the damp straw is prone to rot. Moreover, the straw dried by the hot air chamber is easier to be crushed after entering the crushing chamber, and the crushed material is finer, which is beneficial to the digestion and absorption of animals.
