seedling system virtual machine
The Old syetem made by virtual machine seedling FengWoWei moldingmachine improvement derived huge volume,complicated structure, low efficiency and high cost. This design from old seedlings system based on virtual machine.On the transmission system and actuators on improved greatly. Thismachine can be used widely in corn, vegetable melon and fruit to wait seedlings system port,This machine adopts single-phase motor do power source,can be in the vast rural practical, need not worry require a higher powervolage problem. This paper has a detailed design of virtual machione of decelerate of seedling and execution system of system components gears and detailed dimension to carry on the design. This maching design using standard looked. shorten design of transmission ratio.torque and power calculation. Belt pulleys, gear bevel gear design calculation and dimension design organization chart, the principle and the scheme assembly drawing.

Screw conveyor is one of the main equipment of soda production, vulgar have "guttural," said.Soda ash in calcination, finished products, screen and distribution process by adopting spiral transport is composed by multi-section spiral leaf, shell is long. Together with large amount of transport materials and high temperature, operating in open stop frequent, spiral leaf total by alternating force, the influence of bending deformation and more. Light person causes vibration, the person that weigh cause spiral shell leaf connection plate bolt fracture, cause operators workload increase, soda production. According to statistics, screw conveyor than other transporters such as: leather belt, condole measures, scraper troubles such as frequency wants relatively more, such as: 31 meters spiral transporters have nine consecutive times have connection plate bolt cracking phenomena, operator brings great trouble, in order to avoid vibration, spiral shell fracture phenomenon, should strengthen before installing spare parts preparation and installation of each process quality control.
Shell with great difficulty: refers to align the centerline a shell of semicircle benchmark, as shown in figure 1 shows. Looking for is the former, should first in a spiral transporters head (part) and tail electromechanical motivation erection a piece of wire line, and ends with corresponding department in weight of heavy hammer, steel wire line close, make head, tail height meets installation size requirements, so, steel wire ends position is the ideal location.
Shell installation Due to the company of self-respect, the rest are everywhere role produces different degree of flexure phenomenon, although calculation wire line the deflection of empirical formulas: f = w (L - X) X / 2gb.
But in installation spiral leaf, still cannot meet the practical requirements. For more than 30 meters of spiral transporters, not a bit of practical calculation is bigger than deflection 2 millimeter. Therefore, completely according to different lengths of deflection formula hang line (different lengths of spiral transport) each point deflections, also is very difficult to guarantee each section at the bottom of the spiral shell YeYu standard clearance.
Shell fixation, through "silver piece" holder and on the basis of Angle and link up, for or spiral transporters usually adopts 75mm Angle, consider shell be heated bilges cold influence, will grow on cutting Angle spiral empty hole, as figure2shows. The retaining bolt pre-compression not excessive, the shell of the tail wheel must not any object block. So, shell will have free channeling dynamic leeway.
