Technical Field
[0001] The utility model relates to the technical field of feed processing, in particular to a highly efficient straw crushing and mixed feed preparation device. Background Art
[0002] Straw is a general term for the stems, leaves and spikes of mature crops. In agriculture, it generally refers to the remaining parts of crops such as corn, wheat and rice after the seeds are harvested after maturity. Straw is rich in nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and can be used as roughage for livestock. For example, a straw crushing and mixed feed preparation device with publication number CN207285150U includes a storage bin, a conveyor belt, a brake device, a steering wheel, a support rod, a cross rod, a hydraulic cylinder, a No. 1 motor, a frame, a No. 2 motor, a discharge pipe, a shut-off valve, a stirring roller, a feed feed hopper, a crushing blade, a stirring shaft, a crushing barrel, a straw feed hopper, a partition, a baffle and a feed mixing box. The partition arranged on the conveyor belt can prevent the straw from slipping. The baffle can limit the movement of the straw and prevent the straw from slipping out of the conveyor belt. The conveyor belt conveys the straw to the top of the straw feed hopper. The inclination angle of the conveyor belt is adjusted by the extension and retraction of the piston rod of the hydraulic cylinder. The cross bar connects the support rod with the side of the cylinder of the hydraulic cylinder to improve the stability of the conveyor belt. The No. 2 motor is started to drive the stirring roller to stir, so that the crushed straw and feed are fully and evenly mixed to facilitate ruminant animals to eat. After crushing, the crushed straw is directly poured into the mixing box, so that large straw particles and impurities will enter the mixing box together, resulting in the quality of the prepared straw feed not meeting the standards. In addition, the crushing cylinder and the feed mixing box are placed side by side on the frame, resulting in a large footprint. Utility Model Content
