Above-mentioned motor driven multi-function variable-speed sower, described seeding box is fixedly connected with frame by fixed support.
Above-mentioned motor driven multi-function variable-speed sower, described seeding box is located between press wheel and positive transport wheel.
Above-mentioned motor driven multi-function variable-speed sower, described engine is fixed by being located at support and the frame of positive transport wheel top, and conveyer belt is in transmission connection by the gearbox on engine and described positive transport wheel.
Above-mentioned motor driven multi-function variable-speed sower, described control handle is provided with the throttle line for control engine rotating speed, and described throttle line is connected with engine.
The advantage of motor driven multi-function variable-speed sower of the present invention is: throttle, gearbox cooperating, make its walking more stable, torque strengthens, and power strengthens, and adopts bicycle shift principle device, multistage speed make seed chimes amount more scientific, rationalize, noise is little, easy operating, convenient adjusting, successful, uses manpower and material resources sparingly.During this machine work, noise is little, and high energy-conservation, motor stabilizing and performance are good, small volume and less weight, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details;
As shown in Figure 1, a kind of motor driven multi-function variable-speed sower, comprise that front end has positive transport wheel 1, rear end has the frame 3 of press wheel 2, in described frame 3, to top, its rear end, extend and be provided with control handle 4, the seeding box 6 with sowing port 5 is set in frame 3, and described seeding box 6 is fixedly connected with frame 3 by fixed support 9.Described seeding box 6 is located between press wheel 2 and positive transport wheel 1.And the engine 7 for driving described positive transport wheel 1 to rotate, described engine 7 is rotationally connected by conveyer belt 8 and positive transport wheel 1, engine 7 can adopt 195 traditional diesel engines, or the diesel engine of other horsepowers, the technological means that this technology is well known to those skilled in the art, can select flexibly, at this, seldom introduce.
Also comprise be located between positive transport wheel 1 and seeding box 6 for controlling the seeding control device of the seed velocity of discharge, described seeding control device comprises the main transformer speed multi-chain gear wheel 11 with front stick 10 of being located on positive transport wheel 1, below sowing port 5, arrange gear lever 12 after having from speed change multi-chain gear wheel 13, described main transformer speed multi-chain gear wheel 11 by chain 14 with from speed change multi-chain gear wheel 13 chains, be in transmission connection, in seeding box 6, be provided with one below sowing port 5, stretch out and extend to from speed change multi-chain gear wheel 13 for the axis of guide 15 driving its action the seed that leads to discharge when speed change multi-chain gear wheel 13 rotates, described front stick 10 is all connected with the speed Control bar 17 of being located on control handle 4 by speed Control line 16 with rear gear lever 12.
For guaranteeing engine stationarity in the running, described engine 7 is fixed with frame 3 by being located at the support 18 of positive transport wheel 1 top, and conveyer belt 8 is in transmission connection with described positive transport wheel 1 by the gearbox 19 on engine 7.On control handle 4, be provided with the throttle line 20 for control engine 7 rotating speed sizes, described throttle line 20 is connected with engine 7.
The present invention is according to bicycle shift principle, the different speeds of travel are set, the kind period of the day from 11 p.m. to 1 a.m in the different sizes of sowing, avoided traditional sower need to pass through to control throttle size, and then the control sower speed of travel is controlled the drawback of seed seeding density, this sower makes amount of seed metering more accurate, simultaneously constructability person operation, guaranteed to the full extent seedling survival rate and the later stage crop maximum production.
Principle: drive gearbox by engine (electronic, fuel oil type), walk to driving wheel by chain gear transmission, drive kind of case to choose spacing in the rows and the chimes amount of seed by the speed change gear of cone pulley again by driving wheel.By gearbox, through chain, be transferred to driving wheel walking, driving wheel main shaft adds a tower sprocket wheel, and rear tower sprocket wheel is given in transmission, and rear tower sprocket wheel is connected on the main shaft of kind of case, and the plectrum by front and back tower human relations carries out speed governing.This sower, engine is provided with throttle line, and throttle line is located at the left side of control handle, control throttle size, engine is rack-mount, and is provided with a gearbox, and gearbox is provided with conveyer belt and is connected with front speed change gear, support is fixed in frame, seeding box is fixed on main shaft and (also a plurality of seeding boxs can be installed, specifically according to actual conditions, determines), and front speed change gear is arranged in frame, rear derailleur is arranged on main shaft, and speed Control is on the right side of control handle.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
