Abstract
A blowing-type precise rice sower for sowing rice seeds in the trays is composed of a seed box, an inclined seed discharging plate under said seed box under said seed box, a group of seed discharging tubers arranged at the outlets of said seed discharging plate, a group of seed sensors arranged above the gap between seed discharging plate and tubes, a group of high-speed air valves for blowing the seeds via said tubes into said tray, a seed recovering tray under said gap, and a drive system. Its working principle is also disclosed.
Description
Technical field
The present invention relates to agricultural machinery, especially relate to a kind of precisive blowing paddy-rice seeder.
Background technology
Present existing rice seeder is at common rice seedling, can realize the defective ejaculation amount sowing in 2-5 grain/cave (rice transplanting area).The principle of the sowing parts that adopt mainly contains mechanical type (sheave and nest eye) and pneumatic type (suction spindle, sucker and cylinder).Super hybridization rice is to rely on its superpower tillering ability, obtains high yield.The super hybridization rice seedling is compared with traditional raising rice seedlings, and hole plate seedling raising is a precise sowing by the defective ejaculation amount sowing lifting in original 2-5 grain/cave, and promptly 1-2 grain/cave does not also have accurate pot seedling seedling device to satisfy the specification requirement in super hybridization rice 1-2 grain/cave at present.
Summary of the invention
The purpose of this invention is to provide a kind of precisive blowing paddy-rice seeder, make seed distribution 1-2 grain seed rice in each alms bowl dish of seedling dish of sowing, make the suitable super hybridization rice plantation of the rice shoot that brings out.
In order to achieve the above object, the technical solution used in the present invention is: comprise kind of a case, seeding board, discharging tube, detecting sensor, seedling dish, recovering tray and high speed air valve; Seeding board is installed in the bottom of kind of case, seeding board is downward-sloping from planting the case outlet, long-armed one-tenth level is installed in the exit of seeding board, one group of " L " shape discharging tube that galianconism is downward, leave spacing between one group of " L " shape discharging tube and seeding board, detecting sensor is installed in the top of one group of " L " shape discharging tube and seeding board spacing, each high speed air valve and one group of long-armed mouth of pipe of " L " shape discharging tube are positioned at sustained height, recovering tray is contained in the below of " L " shape discharging tube and seeding board spacing, recovering tray is positioned at the below of high speed air valve, one group of " L " shape discharging tube galianconism outlet is aligned in the below seedling dish alms bowl dish separately, drive system driven by stepper motors is connected with the seedling dish, be contained in the below of seedling dish, seedling dish position is lower than recovering tray.
Described seeding board cross section is the plate of " V " type groove, and the alms bowl dish number of the number of seeding board " V " type groove, number, high speed air valve and the every row of seedling dish of one group of " L " shape discharging tube equates.
The beneficial effect that the present invention has is: the seed rice that comes out from kind of case drops on the seeding board, moves to low side from high-end along seeding board.When seed rice left seeding board, detecting sensor had detected seed rice through out-of-date, and the high speed air valve is opened, seed rice is blown into discharging tube, fall in the seedling dish alms bowl dish under the discharging tube other end, the seed rice that guarantees to fall into the alms bowl dish makes the suitable super hybridization rice plantation of the rice shoot that brings out at 1～2.It is a kind of efficient, reliable, accurate seeding method of saving seed rice.
Description of drawings
Fig. 1 is a structural principle front view of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. kind of case, 2. seeding board, 3. one group of " L " shape discharging tube, 4. detecting sensor, 5. seedling dish, 6. recovering tray, 7. high speed air valve, 8. drive system, 9. seed rice, the A. seedling dish direction of motion.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention includes kind of case 1, seeding board 2, discharging tube 3, detecting sensor 4, seedling dish 5, recovering tray 6 and high speed air valve 7; Seeding board 2 is installed in the bottom of kind of case 1, seeding board 2 is downward-sloping from planting case 1 outlet, long-armed one-tenth level is installed in the exit of seeding board 2, one group of " L " shape discharging tube 3 that galianconism is downward, one group of " L " shape discharging tube 3 and 2 of seeding boards leave spacing, detecting sensor 4 is installed in the top of one group of " L " shape discharging tube 3 and seeding board 2 spacings, each high speed air valve 7 and one group of " L " shape discharging tube 3 long-armed mouth of pipe are positioned at sustained height, recovering tray 6 is contained in the below of " L " shape discharging tube 3 and seeding board 2 spacings, recovering tray 6 is positioned at the below of high speed air valve 7, one group of " L " shape discharging tube 3 galianconism outlet is aligned in the below seedling dish 5 alms bowl dish separately, drive system 8 driven by stepper motors is connected with seedling dish 5, be contained in the below of seedling dish 5, seedling dish 5 positions are lower than recovering tray 6.
Described seeding board 2 cross sections are plates of " V " type groove, and the alms bowl dish number of the number of seeding board 2 " V " type groove, number, high speed air valve 7 and seedling dish 5 every row of one group of " L " shape discharging tube 3 equates.
During operation, seed rice 9 comes out from kind of case 1, along seeding board 2 from the high-end low side that moves to.Detecting sensor 4 is installed in the low distolateral of seeding board, when having detected seed rice 9 and having left seeding board 2, signal to control system, control system signals for high speed air valve 7, high speed air valve 7 is opened, the seed 9 that will fall is blown into discharging tube 3, and seed rice 9 moves along discharging tube 3, falls in the alms bowl dish of discharging tube 3 belows.
Seedling dish 5 whenever moves once, and corresponding high speed air valve 7 each switch once guarantee that the seed rice that falls in the dish of cave is 1～2.When high speed air valve 7 was closed, the seed rice 9 that falls from seeding board 2 directly fell into recovering tray 6.
Described high speed air valve is meant the air valve that 100HZ is above.Driving mechanism is to adopt stepper motor to drive.Detecting sensor is to adopt photoelectric sensor.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
