Abstract
This paper studies the design platen earth bowl machine is a new type of machine. This earth bowl machine function can finish feeding, the earthen bowl of processing, high production efficiency. In the machine work process, each homework links such as feeding quantity, rate stability of such links can get effective control. Meanwhile the machine can produce 10800 earthen bowls per hour, which can be widely used in cotton, corn, melon and fruit, flowers, etc for the production of crops earthen bowl of nutrition.
This paper mainly design content: the design scheme determined; Motor choice; The axis of rotation speed, torque and power calculation; The sprocket, gear design and calculation; The sprocket, gear, CAM size calculation and scheme figure, drawings and component drawing. This paper is the detailed design of the platen earth bowl machine the transmission system and actuators. This paper was designed in detail of the transmission system and the virtual machine for various parts of executive branch, made specific structure size design, and the load larger parts of the precise respectively. Not only to the earth bowl machine of cylinder assembly drawings and parts drawing machine on the 2D rendering of the system, but also in the system of the whole machine assembly drawings , the three-dimensional modeling and simulation. The machine design, application of standard greatly shortened design workload and reduces the production cycle and costs.
Keywords: Earthen bowl of nutrition ; Earth bowl machine ; platen
