Height for axle center is different, using spiral spacing module 46 as shown in Figure 6 in present embodiment.In practical application
In, gear control handle can have OFF gears (locking shelves), can also there is 1-5 grades, even more many gears, and shelves control handle turns
During to OFF gears, thimble 47 is contacted with the highest face of spacing module 46, and when pressing the first trigger 48, thimble 47 is supported soon
To spacing module 46, discharging opening 13 is hardly opened, when shelves control handle goes to digital gear, thimble 47 and spacing module 46
Correspondence profile face contact, when pressing the first trigger 48, the stroke limiting of valve 10, discharging opening 13 is opened corresponding size, is played
The effect of flow adjustment.
Knowable to from foregoing description, when the first shutter 3 is in operating position, the scope for spreading out area reduces, if adopted
Material is broadcasted sowing with same traffic, can make to broadcast sowing density increases, density is substantially constant, it is necessary to both adjust simultaneously to keep broadcasting sowing,
Inconvenience is produced in actually manipulation.So the present inventor devises link gear 43 so that hidden in control first
When baffle plate 3 moves to operating position, the discharging flow of linkage limitation discharging opening 13, likewise, controlling the first shutter 3 to reclaim
During to stowed position, linkage increases the discharging flow of discharging opening 13.
The structure and connected mode of link gear 43 and its peripheral devices are as follows：Push button 41 passes through link gear 43 and first
Connector 8 is connected, and one end of link gear 43 is supported in the side of spacing module 46；Bayonet socket 422 is pushed into push button 41
When putting, link gear 43 promotes spacing module 46 to be moved to the direction away from link gear 43, the spacing module 46 of the correspondence of thimble 47
Position move to another Special-Shaped Surface from a Special-Shaped Surface.
As shown in Fig. 6 and Fig. 7 a, the contoured surface that spacing module 46 is supported by thimble 47 includes at least two Special-Shaped Surfaces, adjacent
At least there is the height difference of a part of correspondence position in two Special-Shaped Surfaces.The quantity of Special-Shaped Surface has two in present embodiment, leans on
The nearly side of link gear 43 is the first Special-Shaped Surface 461, is the second Special-Shaped Surface 462 away from the side of link gear 43；The height of the first Special-Shaped Surface
Height of the degree more than or equal to the second Special-Shaped Surface of correspondence position.Meanwhile, the first Special-Shaped Surface and the second Special-Shaped Surface are spirality, the
The difference in height of one Special-Shaped Surface and the second Special-Shaped Surface diminishes as the height of contoured surface is raised.It is noted that shaped face can
To be have reeded face such as Fig. 7 a, groove is corresponding with gear, and the stabilization for ensureing thimble is supported, and can also be smooth table
Face such as Fig. 7 b, smooth surface is more convenient for the regulation of gear.
The operation principle to above-mentioned ganged movement mechanism is illustrated now：In user's manipulation spreading gear first blocks
During plate 3, push push button 41 to bayonet socket 422 position from initial position, push button 41 can receive the position-limiting action of groove 421 (see Fig. 4 a),
Moved to the direction of spring 49, spring 49 is compressed, and because the position of thimble 47 does not change, so thimble 47 is relative to spacing
The position of module 46 is moved on height contoured surface higher (i.e. the first shaped face 461), if now along axle center cross directional variations
The first trigger 48 is pressed, the opening degree of discharging opening 13 will reduce, discharging flow is also just small, it is achieved thereby that flow is starting
Broadcast sowing the automatic purpose for reducing during scope push button 41.If user exits push button 41 from bayonet socket 422, due to the resilience of spring 49
Effect, spacing module 46 returns to initial position as the opposite direction movement of spring, push button 41 along groove 421, thimble 47 relative to
The position of spacing module 46 returns to profile bottom surface (i.e. the second shaped face 462).
In addition, it is noted that the transition face of transition different height is inclined-plane or arcwall face in Special-Shaped Surface.Certainly may be used also
To be parallel to the plane of axis direction.Because when the first trigger 48 is pressed, thimble 47 and spacing module 46 support contact,
If now user promotes push button 41 so that the transverse shifting of spacing module 46, thimble 47 will be in the contoured surface of spacing module 46
Upper frictional movement, or even transition face is clashed into, so can preferably avoid thimble 47 and spacing module using inclined-plane or arcwall face
Shock between 46.
Dimensional structure on spacing module 46 is further described below：Two size computing methods of Special-Shaped Surface can be as
Under：
The respective notch radius of each gear radius=the second Special-Shaped Surface of the first Special-Shaped Surface+(the maximum open size of discharging opening 13-
The tumbrel openings of sizes of gear setting) * flows reduction percentage；
Each gear radius=base radius of the second Special-Shaped Surface+(the maximum open size of discharging opening 13-gear setting is applied
Fertile car openings of sizes)；
