Specific implementation mode
It further illustrates the present invention with reference to the accompanying drawings and embodiments.
Embodiment：The paddy rice hole seeding of the present invention quantifies seeding combination unit, including feed shaft 1, two side shields 2, blank are filled out
Fill wheel 3, involute-type seed wheel 4 and drive sprocket 5.Two side shield 2, blank filling wheel 3, involute-type seed wheel 4 are equal
On feed shaft 1, the feed shaft 1 passes through two side shields 2, blank filling wheel 3, involute-type seed wheel 4, is allowed to combine
For an entirety.Two side shields 2 are installed, blank filling takes turns the position of 3, involute-type seed wheel 4 as six sides on the feed shaft 1
Axle construction carries out radial positioning to realize to two side shields 2, blank filling wheel 3, involute-type seed wheel 4.The feed shaft
1 six square axle structure both ends are respectively equipped with 1 two side shield 2, and two side shield 2 makes blank filling wheel 3 or involute-type row
Kind wheel 4 is separated with seeding shell, avoids generating frictionally damage.Blank filling wheel is installed among described 2 two side shields 2
3 and involute-type seed wheel 4, the blank filling wheel 3 is identical with 4 axial length of involute-type seed wheel, so as to mutual
It replaces.The involute-type seed wheel 4 is rice Chong Zhong mechanisms, is the most critical component for determining seed-metering performance；The involute
Type seed wheel 4 is to form cavitation seeding, to form intermittent cavitation.The involute-type seed wheel 4 can be filled with blank
Wheel 3 is replaced, and blank filling wheel 3 is in cylinder, shows smooth, not fill kind type hole, without filling kind and the work(of seeding
Energy.Therefore, according to agriculture requirements such as sowing time, line number and breadth to rice growing amount demand, involute-type seed wheel 4 can be with
It is adjusted between 3 ~ 8, the involute-type seed wheel 4 disassembled is filled wheel 3 with blank and replaced.It is equipped in 1 one end of feed shaft
Drive sprocket 5, power and driving feed shaft 1 for receiving external transmission rotate, to make involute-type seed wheel 4 rotate into
Row cavitation seeding.
The involute-type seed wheel 4 includes hexagonal hole 41, shell 42, spaced teeth 43, seeding type hole 44, the involute
The center of type seed wheel 4 is hexagonal hole 41, and the hexagonal hole 41 passes through feed shaft 1, the hexagonal hole 41 to coordinate reality with feed shaft 1
The radial positioning of existing involute-type seed wheel 4.The outer ring of the shell 42 of the involute-type seed wheel 4 is evenly distributed between 10
It is separated by spaced teeth 43 between tooth 43 and 10 seeding type holes 44, the seeding type hole 44.The seeding type hole 44 is in gradually
Involute shape, the seeding type hole 44 include left wall face 45 and right wall 47, and the left wall face 45 is generated according to involute 46
's；The right wall 47 is generated according to involute 48.The track of the involute 46 is the involute shape for tilting arcuation,
Kind is filled to be conducive to rice paddy seed；The path line of the involute 48 is big compared with 46 radian of involute, is conducive to water to be formed with
Rice is launched.Be in involute shape by the seeding type hole 44 that involute 46 and involute 48 are formed, be conducive to seed fill kind and
It charges seed, improves seed-metering performance.
Since rice paddy seed tillering ability is strong, it is contemplated that environment influences the problem of planting percent, therefore the generally sowing 3 ~ 4 per cave
Grain seed then need to sow 18 ~ 24 seeds according to 6 rows of sowing, paddy rice hole seeding of the invention quantify seeding and combine the unit be then by
Complete the seeding of multirow seed in cave；The quantity of involute-type seed wheel 4 is calculated according to seeding line number and per seed number per, if sowing
6 rows, then the quantity of involute-type seed wheel 4 is 4, and the quantity of blank filling wheel 3 is 4；It sows 8 rows and flow rate requirement is low
When, then the quantity of involute-type seed wheel 4 is 5, and the quantity of blank filling wheel 3 is 3.4 He of involute-type seed wheel
The sum of the quantity of blank filling wheel 3 is 8, can synchronize and be adjusted to the quantity of involute-type seed wheel 4 and blank filling wheel 3
Section, meets the requirement of rice flow rate.
Working principle of the invention is as follows：It requires to determine and pacify according to rice paddy seed mechanical and physical property, tiller feature and flow rate
Install involute-type seed wheel 4, blank filling wheel 3 and feed shaft 1.When the paddy rice hole seeding quantifies seeding combination unit work,
Drive sprocket 5 receives external impetus driving feed shaft 1 and rotates, and feed shaft 1 drives two side shields 2, blank filling wheel 3, involute
4 common rotation of type seed wheel, in the areas Chong Zhong, seed enters under gravity, disturbance comprehensive function is conducive to take seed gradually
The seeding type hole 44 of the type that bursts at the seams seed wheel 4, to complete seed-filling process；The left wall face 45 designed according to involute 46 is conducive to water
Rice is filled with；Involute-type seed wheel 4 is rotated into area of charging seed, and the right wall 47 of design is conducive to seed and charges seed, Bu Huifa
It is raw to block.During seeding, two side shields 2 and 3 surfaces of blank filling wheel are smooth, will not plant and charge seed there is a phenomenon where filling.It adopts
Involute-type seed wheel 4 makes the discharge of rice paddy seed cavitation require line number（6,8,10 rows etc.）Rice paddy seed quantity.It charges seed
Afterwards, involute-type seed wheel 4 reenters the areas Chong Zhong, into the cyclic process of next stage.
The paddy rice hole seeding quantifies the workflow that seeding combines the unit：Involute-type seed wheel 4, blank filling wheel are installed
3 and feed shaft 1 --- adding kind, --- drive sprocket 5 rotates, and --- feed shaft 1 drives --- involute-type seed wheel 4 fills kind ---
Involute-type seed wheel 4 takes kind, and --- involute-type seed wheel 4 is charged seed --- cavitation seed is discharged in involute-type seed wheel 4 ---
It completes a seeding cycle --- involute-type seed wheel 4 fills kind --- and recycles seeding process.The paddy rice hole seeding quantifies seeding group
It attaches together the left and right wall surface difference involute-type pore structure set, blank filling wheel 3 and involute-type seed wheel 4 and combines regulated fertilization amount
Mode and implementation result have the advantages that apparent innovative and notable.
The present invention, which works, is embodied effect：Difference rice growing amount requirement solved by the invention, realizes rice precision amount
The total flow rate of bunch planting realizes quantitative, variable bunch planting, solves that current monomer-type rice feed mechanism for seed is complicated, seeding precision is inclined
Low problem.The results are shown in Table 1 for the seed-metering performance of different involute-type seed wheels and rotating speed by the present invention.
The seed-metering performance test result of the different rice varieties of table 1
Table 1 shows that involute-type seed wheel and rotating speed have flow rate the preferable flow rate that adjusts to act on, and disclosure satisfy that difference
The requirement of working width and flow rate, and rotating speed coefficient of variation in 20 ~ 40r/min is less than 0.8%, has preferable seeding
Energy；It has also been found that cavitation performance is good in testing simultaneously.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, the essence of technical solution of the present invention is not departed from
God and range and modify to technical scheme of the present invention or replace on an equal basis, should all cover the present invention claim model
In enclosing.
