Embodiment:
Air-sucking type is automatically made dibbling machine with bowls can be divided into nutritive cube shaping mechanism and dibbling casing mechanism.Wherein the feature of nutritive cube shaping mechanism be six hollow cylinder die cavitys (19) are set below loading hopper (21) shaping mould (18) shaping mould up and down periphery have gear.As shown in Figure 1, electromotor (25) is by belt wheel (23) v band (24) driven gear case (17), and the output shaft that gear-box makes progress drives shift fork (22) and puddler (20).And cooperate with gear that shaping mould (18) is gone up the following peripheral.Bent axle one (13) and connecting rod one (11) drive a slide bar that can slide up and down (16) that is positioned at the shaping mould top, as shown in Figure 8, locate to be provided with upper punch and push away the alms bowl drift with the corresponding die cavity of shaping mould (19) on the slide bar.Also by tappet that can move up and down of a cam mechanism driving and low punch, this upper punch is corresponding with low punch for gear-box.Its concrete operation principle can be 94242213.9 cotton nutrition forming machine with reference to the patent No..
The dibbling casing mechanism is mainly by the air-sucking type dibbler, and covering device is planted case and earthing case, and the power transfer part constitutes.Air-sucking type dibbler and covering device are cemented on the one rotating shaft, and be shown in Figure 4 as Fig. 3, the fixed gear of an end of gyroaxis (2), and gear (2) and tooth bar (3) match.And tooth bar (3) is consolidated with rack bar (12), under the guide function of two tooth bar sliding supports (4), can do axially-movable.Gear-box (17) two (31) acts on toggle by axle, and drives rack bar and tooth bar moves reciprocatingly, and reciprocating stroke is 3/4 length of gear (2) root circle.Therefore work as tooth bar and move reciprocatingly once, gear (2) just rotated for 3/4 week, and went back to original position, can pass through Fig. 2, shown in Fig. 3 contrast, under state shown in Figure 2, gyroaxis and gear (2) 3/4 circle that need turn clockwise just can arrive position shown in Figure 3.The air-sucking type dibbler and the covering device that are cemented in like this on the gyroaxis just can be travelled to and fro between kind of case earthing case (5) and die cavity (19) top, and seed (6) and earthing (41) are taken in the interior nutritive cube (32) of die cavity.
As shown in Figure 5, one five volts electromotor (35) are equipped with in air-sucking type dibbler inside, are fixed on by motor fixing frame (36) on the barrel-shaped shell of dibbler.Five volts of motor shaft ends have a centrifugal fan blade (33), and its effect can thereunder form air negative pressure when being rotation, makes outside air be inhaled into from seed-taking device suction nozzle (10), discharge from the fan propeller top.As shown in Figure 2, when seed-taking device suction nozzle (10) forwarded in kind of the case near seed, seed can tightly be adsorbed on the seed-taking device suction nozzle under the effect of air negative pressure.Because the aperture of seed-taking device suction nozzle (10) is slightly less than average seed diameter, so seed can not be inhaled into seed-taking device, and only can adsorb a seed at every turn, guaranteed to get kind of a precision.For the not too full seed of minority, or the very irregular seed of shape, the seed-taking device suction nozzle will be difficult to that therefore its absorption also had certain seed selection function.The root of seed-taking device suction nozzle (10) has a valve, mainly by spool (34), and valve pocket (38), valve core reseting spring (37) constitutes.When the air-sucking type dibbler is in as shown in Figure 2 the position, the configuration state of this valve as shown in Figure 7, tracheae in the spool and seed-taking device suction nozzle pipe are on same axis, the circulation of air circuit is unimpeded, the negative pressure that centrifugal fan blade (33) produces can be delivered to the seed-taking device suction nozzle smoothly, is convenient to get kind.When the air-sucking type dibbler is in as shown in Figure 3 the position, need to cut off negative pressure air, make seed can drop to smoothly in the nutritive cube (32), this Shi Tong Guo ?piece two (29) realize.As shown in Figure 3, the spool You Yu of valve ?the existence of piece two (29), and headed among the valve pocket (38), and this moment valve state as shown in Figure 6, seed-taking device suction nozzle pipe is interrupted, and air is inhaled in a side of spool, and the place of leading to seed one end is alleviated negative pressure rapidly after also blowing air enters mutually with atmosphere, and seed loses the negative pressure support, drops in the nutritive cube under the effect of gravity.
As shown in Figure 9, covering device is by earthing cap (9), and earthing chamber (27), earthing cap back-moving spring (39), earthing cup locator pins (40) constitutes.When covering device is in position shown in Figure 2, the covering device interior as shown in Figure 9, Figure 10 is the end view of Fig. 9, reference simultaneously.Earthing cap and earthing cup locator pins are consolidated, under Fig. 9 state, earthing cup locator pins Zai ?move backward under the effect of piece, compression earthing cap back-moving spring (39), the earthing cap separates with earthing chamber (27).The earthing chamber is the pipe of one section hollow, and when the earthing case was submerged in the earthing chamber, powdery earthing (ash or light matrix and so on) will enter into the earthing chamber naturally.As shown in figure 11, when covering device leaves the earthing case, the earthing cup locator pins (40) Bai Tuo ?the constraint of piece, earthing cap back-moving spring is extended, and the earthing cap has sealed the hole at two ends, earthing chamber under the effect of spring, make the powdery earthing of filling in the earthing chamber be closed, avoid in the motion process of covering device, leaking.When covering device is in position shown in Figure 3, You Yu ?the effect of piece one (28), covering device is in state shown in Figure 9 again, the earthing cap is opened, the powdery earthing in the earthing chamber drops under the effect of gravity on the nutritive cube (32) in the die cavity naturally, covers seed.So far the nutritive cube that has seed and earthing just completes, and is rushed out die cavity during again through upper punch, drops on the conveyer belt (7).
Kind of case and earthing case are placed in together, as shown in Figure 4, are the earthing casees at the covering device correspondence position, can fill the powdery earthing in the earthing case, and for example light matrix of ash and so on can make the resistance of covering device when streaking earthing reduce like this.And below air-sucking type dibbler correspondence position, be kind of a case, a kind case baffle plate (26) also is set in kind of case, its structure can be with reference to the correspondence position among Fig. 3 Fig. 4, and its effect is the degree of depth that keeps seed in kind of the case.When the removed part of seed, the seed of planting case baffle plate periphery enters additional from following gap under the acting in conjunction of gravity and machine vibration, make kind of the seed height that case baffle plate (26) is inboard remain at that the air-sucking type dibbler is only to be got on kind of the height, can avoid too much seed to be taken out of kind of a case by seed-taking device suction nozzle (10).
