Understand the purpose of this utility model, characteristics and advantage for clearer, preferred embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the assembly stereogram of a preferred embodiment of the driving mechanism of pin type vacuum planters of the present utility model.
Embodiment
As shown in the figure, a preferred embodiment of the driving mechanism of pin type vacuum planters of the present utility model comprises: a fixing seat 1; At least two crank groups 2 are arranged to two in the present embodiment, and described crank group 2 is connected in the two ends of a longeron 4, and longeron 4 wears by described fixing seat 1, and crank group 2 drives swing by driving power such as actuating cylinder (not shown); Two adsorption tubes 3, they lay respectively at the both sides of described longeron 4 and are fixedly connected on the inner edge both sides of described fixing seat 1, and its stroke is in the overlapping alignment of central authorities, at a plurality of upright absorption pins 5 of vertically being furnished with of adsorption tube 6; Be positioned at the seed tube 6 of the overlapping below of described adsorption tube 3 strokes, form vertically that arrange and the described pin 5 vertical a plurality of through holes 8 that align that respectively adsorb on it; Be positioned at seed tube 6 belows and after moving, can coil (not shown) by a conveyer belt (not shown) drive with each described through hole 8 corresponding a plurality of cave; Two seed troughs 7 are separately positioned on below the two ends of described adsorption tube 3 upset strokes, and they are separately fixed on the oscillator 9.Described crank group 2 is to adopt parallel four-bar linkage as shown in the figure.
To specify the operation principle and the course of work of the driving mechanism of pin type vacuum planters of the present utility model below.
When the displacement movement that conveyer belt drive cave dish work intermittently advances, the semi arch shift reciprocately that crank group 2 will cooperate the motion of conveyer belt also to do intermittence moves.Because crank group 2 is a parallel four-bar linkage, can make fixing seat 1 remain on horizontal level when doing the semi arch displacement.Adsorption tube 3 of fixedlying connected with fixing seat 1 and absorption pin 5 are respectively by the two groups of solenoid control absorbed seeds independently and the action of placing seed.When one of double adsorption tube 3 was parked in the top of a seed trough 7, another adsorption tube 3 just was parked in the top of a seed conduit 6.At this moment, the adsorption tube connection vacuum source that is parked in these seed trough 7 tops carries out the action of absorbed seed, and the adsorption tube 3 that is parked in seed tube 6 tops is then connected the high-pressure air source of destruction vacuum to place the action of seed.Crank group 2 was also moved and is made the place-exchange of adsorption tube 3 when conveyer belt advanced, and make the adsorption tube 3 that is parked in these seed trough 7 tops originally change the top that is parked in seed tube 6, and the adsorption tube 3 that is parked in above the seed tube changed the top that is parked in seed trough 7.Switch and control two groups of magnetic valves of adsorption tube 3 this moment, make the script absorbed seed switch to the placement seed, originally place seed and switch to absorbed seed.Like this, cooperate the preceding and then crank group of conveyer belt and fixing seat drive adsorption tube to make continuous change action, thereby realize the purpose of sowing.
As shown in the figure, because both sides all are provided with seed trough 7, and seed trough 7 is fixed on the oscillator 9, seeds in the seed trough 7 is rolled beat and increases the probability that adsorption tube 3 is drawn, and then improve planting rates.Fixing seat 1 and adsorption tube 3 connect one and become an assembly, like this, only need change screw when changing sowing cave dish specification and adsorption tube 3 and seed tube 6 can be taken off replacing; And after changing adsorption tube 3 and seed tube 6, only need the bist data of electric cabinet is switched to the action that the data of coiling in used cave can be finished the sowing cave dish of being changed, therefore more convenient than traditional pin type vacuum planters.If when using staggered cave dish, an adsorption tube assembly that only needs to change special-purpose hole bit interleave get final product, this kind of coiling than the sowing cave that traditional pin type vacuum planters can be suitable for is more.The crank group 2 that is adopted has the effect of amplifying stroke: driving mechanism mobile phase same distance, framework with crank group 2 of the present utility model is removable far away, like this, only need move less distance by crank group 2 drive adsorption tubes 3 assemblies and can cover the distance that traditional cylinder will move; The responsiveness of the actual crank group of finishing is than the fast several times of traditional cylinder, and therefore, operating efficiency is higher.In addition, because two adsorption tubes 3 of the present utility model separately distinctly move by two groups of solenoid control, drawing a kind period of the day from 11 p.m. to 1 a.m when adsorption tube 3 wherein, another root adsorption tube 3 is just being placed seed and is being coiled to the cave; Traditional pin type vacuum planters then is to draw seed when cylinder advances, and places seed when retreating.By contrast, traditional pin type vacuum planters has only the stroke folk prescription to sowing, and the utility model can be realized the twocouese sowing of stroke, thereby has greatly improved sowing efficient.
