The whole-grain feed truck is a special equipment used in the field feeding. It is the equipment to deliver the finished ration mixed by the twhole-grain feed mixer to the cowshed and then to the feeding area, it is a more perfect product, which is formed by adding a spreading device on the basis of the ordinary truck, and through the practice of many pastures and many improvements, and it greatly reduces the feeding workload of the large-scale breeding farms, the mechanization of feeding was achieved. The power to transmit and dispense material comes from a hydraulic pump, which takes force directly from the engine. Speed from the speed, the box on the power by the clutch, to ensure that the independence of the work in spreading material. Because the ration contains a lot of longer crude fiber, the spreading process is easy to jam. Therefore, the use of agitator in the box material transmission mode not only improves the reliability of the equipment, solves the high failure rate caused by a large number of parts, but also improves the uniformity of material withdrawal.
