The invention relates to the technical field of
straw collection, pressing and bundling through agricultural machines, and discloses a
straw collecting and briquetting vehicle which comprises a
chassis, a collecting device, a conveyer belt, a
hay cutter, a multistage roll
straw forming device and a collecting hopper. During a working process of the vehicle, the collecting device picks up straws on the ground to a collecting bench, a material poking wheel conveys straws on the collecting bench to the conveyer belt, and the conveyer belt conveys straws into the
hay cutter. The
hay cutter chops straws in certain length and conveys the straws into the multistage roll straw forming device, straws in the multistage roll straw forming device are rolled into high-density straw bars by continuous multistage rolls, and the straw bars are
cut by a cutter to form high-density straw blocks which fall onto the collecting hopper from a
discharge hatch. The straw collecting and briquetting vehicle realizes continuous collection, conveying and multistage rolling, and is a self-propelled combined operation device which shape straw blocks with high-density and no bundling ropes. The high-density straw cubes can be used as agricultural building materials or fuel.
