Description
Technical field
The utility model relates to accurate agricultural machinery technological field, mainly is point disk seedling growing seed placing device technical field.
Background technology
At present, the domestic vacuum air-suction type accurate sower that is used for point disk seedling growing mainly is two big types: one type is that pin is inhaled the formula precision planter, and another kind of is board-like precision planter.The subject matter that pin suction formula precision planter exists aborning is the control system complex, and manufacturing cost is high, is difficult for promoting.The plate type hole disc sowing need to be inhaled kind of plate and between cave dish and seed pan, is moved around, or seed pan and cave plate wheel change to move to inhale and plant below the plate, and duty is intermittent, exists production efficiency lower, the problem that amount of operation labor is big.Inhale kind of plate in addition when suction is planted; Suction hole is prone to be stopped up by broken kind or foreign material and causes the hole, when seed is blocked by suction hole, leans on the deadweight of seed to be difficult to fall in the dish of cave and causes the hole; Can only sow the seeding and growing seedling of single variety or a few variety seeds cave dish; The sowing continuity is relatively poor, and leakage sowing rate is higher, waste seed consumption.
Summary of the invention
The purpose of the utility model is the deficiency to China's demand of practical production and prior art; A kind of vacuum adsorption type seed placing device is provided; Sowing can be carried out continuously, reduce leakage sowing rate, reduce the seed waste; And can carry out the sowing of each specification seed, satisfy the seeding and growing seedling of different caves such as various vegetables, flowers dish.
To achieve these goals, the utility model has been taked following technical scheme.
Vacuum adsorption type point disk seedling growing seed placing device, comprise level central shaft, be set in lid of band edge on the central shaft and drum cover cylinder, be set on the central shaft and be positioned at the drum cover outside sprocket wheel, be arranged at cylinder side top and the seed chamber that is abutted against with cylinder, be arranged at the cylinder bottom can be along drum shaft to the scraper plate that scrapes; On the barrel of cylinder, being uniformly distributed along the circumference offers axial vacuum chamber, all is evenly equipped with one group along the length of each vacuum chamber and radially connects the suction hole to barrel from vacuum chamber, in each suction hole, all is equipped with to inhale kind of a mouth; Offer the adapter cavity of the perforation of docking with vacuum chamber at the roller end cover sidewall, the outer end of adapter cavity is communicated with vacuum extractor; On sprocket wheel, be set with carrier chain, the equidistant cave dish that is placed with on carrier chain.
The aperture that the utility model is inhaled kind of mouth is 0.25mm.The narrow structure of seed chamber for being abutted against along drum length, on vibrating mass is arranged, during work, vibration makes seed be in the jump suspended state, when on the cavity length of taking seriously one group was inhaled kind of mouth through seed chamber, each inhaled absorbed seed on kind of mouth.The narrow structure of seed chamber for being abutted against along drum length, one group of suction hole on vacuum chamber length of the each cover cap of seed chamber.The pitch of carrier chain equates with cave, the kind cave distance of cave dish.
Adopt the utility model, vacuum extractor is communicated with the vacuum chamber of cylinder wall through adapter cavity, after the vacuum extractor work; Can in vacuum chamber, forming negative pressure, when cylinder along with sprocket rotation, when on the cylinder wall one group is inhaled kind of mouth through seed chamber; Inhale kind of a mouth and under suction function, adsorb seed, barrel is rotated further, when the seed-bearing suction kind mouth of absorption is positioned at bottom; Inhaling kind of a mouth coils through the cave; The blocking-up source of the gas also discharges negative pressure, and under the effect of release and seed deadweight, scraper plate is scraped seed in the kind cave that falls into the cave dish.
The cylinder of the utility model can constantly rotate along with sprocket wheel, realizes sowing continuously, its high efficiency, can reach 600-1000 to coil/hour.Because seed is to be adsorbed on to be brought to dish position, cave in kind of the mouth and to sow, seed is difficult for spilling, and not only seed is wasted for a short time, and leakage sowing rate is low.Whatsoever the seedling culture hole plate of seed as long as place it on the carrier chain, is inhaled kind of the seed of mouth absorption and all can be broadcast exactly in the dish of cave.
Further set forth the content of the utility model below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of vertically cutting open along Fig. 1 intermediate roll central axis.
Embodiment
Like Fig. 1, shown in Figure 2, the utility model comprise level central shaft 2, be set in lid 12 of band edge on the central shaft and drum cover 3 cylinder 4, be set on the central shaft and be positioned at the drum cover outside sprocket wheel 1, be arranged at cylinder 4 sides top and the seed chamber 11 that is abutted against with cylinder, be arranged at the cylinder bottom can be along drum shaft to the scraper plate that scrapes 10.Sprocket wheel 1 is fastening with central shaft 2, and cylinder 4 rotates with sprocket rotation.On the barrel of cylinder 4, being uniformly distributed along the circumference offers axial vacuum chamber 6, all is evenly equipped with one group along the length of each vacuum chamber and radially connects the suction hole to barrel from vacuum chamber, in each suction hole, all is equipped with to inhale kind of a mouth 5.The material that present embodiment is inhaled kind of mouth 5 is a copper, and thickness is 4mm, and the aperture of inhaling kind of mouth is 0.25mm; Offer the adapter cavity 9 of the perforation of docking with vacuum chamber 6 at roller end cover 3 sidewalls, the outer end of adapter cavity is communicated with vacuum extractor, and vacuum extractor can directly adopt vavuum pump, is used to control the size of negative pressure in the vacuum chamber 6.On sprocket wheel 1, be set with carrier chain 7, the equidistant cave dish 8 that is placed with on carrier chain, the pitch of carrier chain 7 equates with cave, the kind cave distance of cave dish 8.Seed chamber 11 is fixed by positioning device above the side of cylinder 4, does not rotate with cylinder 4.The narrow structure of seed chamber 11 for being abutted against along drum length; Rotation along with cylinder; But the each cover cap of seed chamber is along one group of suction hole arranging on the vacuum chamber length and be installed on suction kind mouth wherein, and when whole group was inhaled kind of mouth 5 through seed chamber, each was inhaled kind of a mouth and all adsorbs seed.
During the utility model work, power set drive central shaft 2 and rotate, and drive cylinder 4 and rotate simultaneously with sprocket wheel 1.Cave dish 8 advances to the direction of cylinder 4 under the drive of carrier chain 7, and sprocket wheel 1 can be used same power set such as motor with carrier chain 7.The outside exhausting of vavuum pump makes and forms negative pressure in the vacuum chamber 6; When cylinder 4 forwards one group to when inhaling kind of mouth and getting into seed chamber 11 directions, the negative pressure of vacuum chamber 6 makes inhales kind of mouth 5 places and adsorbs seed, and cylinder 4 is rotated further; Under forwarding to; Under the effect of release and seed deadweight, seed is through scraper plate 10, and seed falls into the kind cave of cave dish accurately.Because the pitch of carrier chain 7 equates that with cave, the kind cave distance of cave dish so the point-to-point speed of the rotary speed of cylinder 4 and cave dish is complementary, when cylinder 4 rotated a circle, the cave dish was just covered a stroke.Cylinder 4 constantly rotates, and the cave dish just constantly advances, and sowing just can continuously be carried out, and finishes until sowing.
