Bags of feed and a single species, the small volume of bulk feed has been unable to meet with the farming industry by the farmers dispersed feeding type to automation, the direction of industrialization, large-scale farms to feed storage and demand and bagged feed irrigation The loading and feed bags demolition costs and labor, feed factory farms need a low-cost, high-efficiency models to transport bulk feed. Bulk feed truck can be loaded at the same time the transport of 1-3 different feed through hydraulic control screw conveyor system to achieve automatic discharge to the the 7m high hopper tower dedicated feed truck. The bulk feed vehicle chassis, cabinet, screw conveyor system, hydraulic drive system, rotary device, attachment structure. The clutch booster control system to the power take off and engine speed control can be achieved in the cab. Bulk feed truck box, feed tank, box part of the design of the frame structure, the outer surface of the steel skeleton connected with bolts, all the links at the coated sealant. The two wagons inner plate and the horizontal screw conveyor is "V" into the word line, to ensure that rely solely on the action of gravity feed down along the inclined plane will be able to fully enter into the screw conveyor and perpendicular to the lateral plate of the chassis with Case blend, vehicle beautiful and coordination. Box a total of four positions, the middle two positions often opening, and that the level of direct access to the screw conveyor, the two positions normally closed position, respectively, with the silo door, only to open the doors to the spiral is connected to the machine. Screw conveyor, screw conveyor system contains a horizontal screw conveyor, vertical screw conveyor, inclined screw conveyor, its diameter were 273,273,219, throughput, from small to large order of priority for the horizontal screw conveyor, vertical screw conveyor, inclined screw conveyor this will ensure a smooth discharge. Before and after the end of the screw conveyor has a sealing device, driven by a hydraulic motor, hydraulic system manual handle control mode steering control and order. Hydraulic drive system hydraulic system is a core part of the bulk feed truck by a hydraulic cylinder reciprocating rotary motor rotating action loop, in order to ensure that the system is reliable, using double vane pump double acting rotary pump and chassis power take off by The universal coupling is connected to the PTO output speed can be changed with the change of engine speed. The overall layout of the decentralized structure, pumps, motors, directional valves and other key components are imported. Rotating means for the the car side inclined screw conveyor the discharge outlet hopper Tata butt inclined spiral needs within a certain range of rotation of the machine in addition to be able to lift, due to the inclined screw conveyor with vertical screw conveyor is integrally connected by a hydraulic cylinder , the choice of device design on a vertical screw conveyor worm reducer and chain drive inclined screw conveyor and vertical screw conveyor is in the range of 180 ° rotation. Basic principles of bulk feed truck to work when I first open the box at the top two positions of the splice mouth filled with the first feed, and to ensure that each compartment loading 3T and then open the top and the last two positions in the splice port, loading the second feed . These two positions normally closed position has a separate positions in the mouth, it can also be loaded two feed, so as to achieve the vehicle shipment three different feed function. Discharge reaches the farm material storage tower, check the operating handle to reach the farm material storage tower to check the operating handle, the unloading valve is open unloading off the clutch, close to the power take off switch in working condition . Pay attention to adjust the speed of the engine is in idle vertical handle on the lifting position to be shut down in the cylinder piston rod protruding the tilt screw machine lift rose material corresponding tower height joystick. Worm gear crank rotary screw machine to adjust the tilting screw conveyor is a gate and the material storage tower butt. Ready in order to open tilt, vertical screw conveyor motor joystick, horizontal screw conveyor motor joystick feed can be continuously transported to the three screw machine when the feed truck transporting two feed hopper tower must be unloading boxes the middle of the body two normally open positions feed and then open the front and rear two positions normally closed doors of the feed drive to the second feed material storage tower is repeated at the first feed discharge end of the process open positions often the closed doors of the drive to the third feed material storage tower at the completion of the whole discharge process now too medium-sized domestic feed mills, farms hundreds of large tonnage bulk feed truck demand is mainly dependent on imports so the models will be broad market prospects. Stainless steel welded pipe with wall thickness of the filter structure shown in Figure cartridge filter with stainless steel mesh count is filtering accuracy allowed by the pump through the smallest debris size filter rolled into a cylindrical placed in the cartridge inside pressure welder spot welding filter cartridge, between the platen firmly snapping the inside of the cartridge. 
