The utility model content

The purpose of this utility model be to provide a kind of rotate to inhale blow the raising rice seedlings disk seeding apparatus of formula, this device realizes that the seedling dish uninterruptedly sows continuously, the sowing process does not stop, and have that seeding apparatus is simple in structure, stable performance, characteristics that sowing efficient is high.

The utility model is achieved in that

A kind of rotate to inhale blow formula raising rice seedlings disk seeding apparatus and comprise frame and be arranged on transport sector and sowing mechanism on the frame, it is characterized in that: described sowing mechanism comprises hopper, plants subchannel and seeding head, hopper is arranged on the top of seed channel entrance, in kind of subchannel, be provided with one and stir bar, seeding head is arranged on the exit of kind of subchannel, seeding head with stir between the bar between adopt gears engaged to be connected.

Described seeding head comprises that rotating suction blows tube and air-breathing axle, inhale the air-breathing through hole that blows the even some groups of axially-aligned that distribute in tube surface in rotation, suction kind of a mouth is installed in air-breathing through hole, described rotation is inhaled and is blown an inner hollow, and two ends by bearing fixing on air-breathing axle, be rotated at air-breathing axle and inhale the bottom of blowing a wrapping portion and be fixed with an inflatable bar, the remainder surface is the some aspirating holes of distribution evenly, offer the inflatable mouth of axial setting in the bottom of inflatable bar, inflatable mouth is connected with the hair-dryer of outside by connecting flexible pipe, on air-breathing axle, also be provided with axially extending bore, this axially extending bore communicates with aspirating hole, the axially extending bore port is connected with induced-draught fan by tube connector, also is fixed with on air-breathing axle and stirs the gear that bar cogs and nibbles mutually.

The utility model improves the sowing mechanism of existing raising rice seedlings disk seeding apparatus, to originally adopt air cylinder driven, step mode of operation makes the mode of operation of the utility model continuous rotary sowing into, dwindle greatly with respect to prior art the utility model volume, reduced the pneumatic control part, simplify the structure, improved operating efficiency.

Embodiment

Shown in Fig. 1-4, a kind of rotate to inhale blow formula raising rice seedlings disk seeding apparatus and comprise frame 1 and be arranged on transport sector 2 and sowing mechanism 3 on the frame, shoe materials device 4 and liquid distribution 5 are set in sowing mechanism 3 the place aheads, sowing mechanism 3 rears are provided with filler device 6, described sowing mechanism 3 comprises hopper 31, plant subchannel 32 and seeding head 33, hopper 31 is arranged on the top of kind of subchannel 32 imports, in kind of subchannel 32, be provided with one and stir bar 34, seeding head 33 is arranged on the exit of kind of subchannel 32, described seeding head 33 comprises that rotating suction blows tube 331 and air-breathing axle 332, inhale the air-breathing through hole that blows the even some groups of axially-aligned that distribute in tube 331 surfaces in rotation, suction kind of a mouth 333 is installed in air-breathing through hole, described rotation is inhaled and is blown tube 331 inner hollow, and two ends are fixed on the air-breathing axle 332 by bearing 334, be rotated at air-breathing axle 332 and inhale the bottom of blowing tube 331 wrapping portions and be fixed with an inflatable bar 335, the remainder surface is the some aspirating holes 337 of distribution evenly, offer the inflatable mouth 336 of axial setting in the bottom of inflatable bar 335, inflatable mouth 336 is connected with the hair-dryer of outside by connecting flexible pipe 339, on air-breathing axle 332, also be provided with axially extending bore 338, this axially extending bore 338 communicates with aspirating hole 337, axially extending bore 338 ports are connected with induced-draught fan by tube connector, also are fixed with on air-breathing axle 332 and stir the gear that bar 34 cogs and nibbles mutually.

The utility model course of work is such: the seedling dish is placed on the transport sector of frame, transport sector is sent to the seedling dish earlier carries out materials device below shoe soil and floating, be sent to liquid distribution below again and water moisteningly, just be conveyed into the below of sowing mechanism then; And seed enters into kind of a subchannel from hopper on the other hand, along with dead man rotates seed is slowly exported from the exit of kind of subchannel, dead man and seeding head pass through the gears engaged interlock, seed slowly in seed channel exit output seeding head rotate synchronously, seed is at first inhaled by the rotation of seeding head and is blown a seeding port absorption, treat that seeding port inhales when blowing tube and rotating to bottommost with rotation, the seeding port correspondence is the inflatable mouth that axially is provided with on the inflatable bar at this moment, the seed that be adsorbed on the seeding port this moment does not lose suction function, be seeded on the seedling dish, rotation is inhaled and blown the surperficial seeding port of tube is that axially-aligned is equally distributed, therefore as long as the seeding head rotation transmits the work that can realize the continuous rotary sowing synchronously with the seedling dish, also can control seed spacing according to seeding head size or rotary speed, the seedling dish of having broadcast seed further is sent to the filler device below to carry out the top layer to carry out soil floating.

The utility model has saved the pneumatic means and the control section thereof of existing seeding apparatus, has saved cost greatly, has improved the finished product cost performance, also realized the mode of operation of continuous sowing simultaneously, can improve sowing efficient, be particularly suitable for large-scale industrialized production, be significant innovation of agricultural machinery.
