A kind of vacuum-seed-taking seeding apparatus, comprising:
Dual-disk integrated formula air cavity described above,
Tracheae axle, described tracheae axle is tubulose;
Case, described case is fixedly connected with one end of described tracheae axle, the side of the close described tracheae axle of described case is provided with gets seed chamber and puts kind of a chamber, and the side away from described tracheae axle of described case is provided with seed feed pipe, and described seed feed pipe is communicated with described seed chamber of getting;
To hold one's breath mechanism, described organization establishes of holding one's breath is in described cavity, described mechanism of holding one's breath comprises fixed mount and the block of holding one's breath for being closed by described suction hole, described fixed mount is fixedly connected with the outer wall of described tracheae axle, described block of holding one's breath is arranged on described fixed mount, fit in the side away from described case of described hold one's breath block and described seed absorbing plate, described in block of holding one's breath corresponding with described kind of chamber of putting.
Air cavity body can with Pivot Point Center line for turning cylinder rotates in the outside of tracheae axle, thus drive seed absorbing plate to rotate, and tracheae axle, case cannot rotate relative to fixing with mechanism of holding one's breath; Cavity is in the state of opposing seal, only have the suction hole of seed absorbing plate to be communicated with case, the gas in cavity is extracted out by tracheae axle and ventilation hole by blower fan etc., and cavity is in negative pressure state, the atmospheric pressure of suction hole both sides is different, and seed can be attracted on suction hole cannot drop.Case is near seed absorbing plate, get seed chamber can be positioned at case below, put the top that kind of chamber is positioned at case, getting in seed chamber of case is placed with many seeds, each suction hole adsorbs a seed through getting seed chamber, seed absorbing plate rotation can make to adsorb seed-bearing suction hole and arrive the position corresponding with putting kind of chamber, put in kind of chamber and generally can be provided with inoculation He Jibozi mechanism, this Bo Zi mechanism can be Ying Bo mechanism or Ruan Bo mechanism, seed on suction hole is dialled and is dropped down onto in inoculation box by Bo Zi mechanism, and the seed in inoculation box is discharged sowing in soil by duckbilled; Seed feed pipe can be got seed chamber and provides passage for seed enters, and guarantees that being carved with seed when getting in seed chamber draws for suction hole.Bo Zi mechanism generally adopts Ying Bo mechanism or Ruan Bo mechanism, and due to the existence of the negative pressure in cavity, larger to guarantee that seed is not easy to drop in seed absorbing plate rotation process to the absorption dynamics of seed, Ying Bo mechanism dynamics is comparatively large, is dialled by the seed being adsorbed on suction hole place by force, can cause certain damage to seed, thus affect germination rate etc., the dynamics of Ruan Bo mechanism is less, can not cause damage to seed, but there will be seed is not dialled the phenomenon falling to causing broadcast leakage; Hold one's breath organization establishes in cavity, namely built-in mechanism of holding one's breath is formed, the normal work of all the other mechanisms can not be affected, fixed mount is fixed by the outer wall of tracheae axle, the two can not relatively rotate, block of holding one's breath can have any shape, and as cuboid, cylinder and other is irregularly shaped etc., one of them suction hole can be closed by the block that only needs to guarantee to hold one's breath completely; Air cavity body drives seed absorbing plate to rotate, when suction hole on seed absorbing plate is closed by block of holding one's breath, a part of negative pressure of the side of the close cavity of seed disappears, the pressure difference of seed both sides reduces, seed still can be attracted on suction hole, now use Ruan Bo mechanism easily to be dialled by seed, damage can not be caused to seed.Certainly, after setting up mechanism of holding one's breath, use Ying Bo mechanism also can not damage seed, in addition by regulating the peak suction in cavity, also can not re-use Bo Zi mechanism and seed can be made to drop above the inoculation box of specifying.
Further, described fixed mount near described in hold one's breath one end of block be provided with slideway, the side away from described seed absorbing plate of described block of holding one's breath is provided with slide block, described skid is embedded in described slideway, the outside of described slide block is arranged with back-moving spring, described back-moving spring is stage clip, and the two ends of described back-moving spring prop up described slideway and slide block respectively.
Slide block can slidably reciprocate in slideway, the direction of sliding is vertical with the surface of seed absorbing plate, thus regulate the position of block of holding one's breath, back-moving spring pressed slider, the block that makes to hold one's breath fits tightly with seed absorbing plate all the time, ensure the air-tightness of block when being closed by suction hole of holding one's breath, avoid because the wear and tear sealing effectiveness that causes of block of holding one's breath is deteriorated, and, slide block slides and can effectively prevent in installation process because the improper sealing caused in block position of holding one's breath is poor or extruding seed absorbing plate makes it damage in slideway, the block that can make to hold one's breath fits tightly with seed absorbing plate all the time, seed absorbing plate can not be extruded again, hold one's breath the insufficient pressure of block to make seed absorbing plate deformed damaged, the moment is not needed to adjust the position of mechanism of holding one's breath, increase work efficiency.
Compared with prior art, the beneficial effects of the utility model are: by air cavity body interior being designed to the form of shoulder hole, seed absorbing plate is embedded in the first shoulder hole, seed absorbing plate and the first shoulder hole are fitted fixing, form Dual-disk integrated formula air cavity, the contact area between seed absorbing plate and air cavity body increases, and sealing effectiveness is therebetween better, can ensure that the negative pressure in cavity reaches the numerical value of setting, the adsorption effect of seed is better.
