Abstract

The utility model relates to a seeder which is formed by overlapping a chassis and seed boards, wherein the two seed boards are connected by a press strip and a locking screw. Double-holes with the same quantity are correspondingly arranged on an upper layer of seed board according to the arrangement of a seedling disk, wherein each hole is composed of a quadrate area and an arch-shaped area and can hold three to four normal seeds. Single-holes with the same quantity are correspondingly arranged on the chassis according to the arrangement of the double-holes of the seed board. When the utility model is used, the seed boards are slid, the seeds can be measured when positions of the upper holes and the lower holes are dislocated and the seed holes are closed. When the seed positions are overlapped, the seeds are sown at the left end and the right end of a horizontal seedling disk twice to realize that the minitype precision seeder can fully sow one seedling disk in one cycle and the purpose of evenly sowing 3 to 4 normal keng rice seeds on each seedling disk is achieved.

Description

Conventional japonica rice seedling-throwing precision seeder

The utility model relates to the sowing seeds technology of conventional japonica rice rice transplanting.

The conventional japonica rice tillering ability is strong not as hybrid rice, thereby requires its seeding quantity more on the high side than hybrid rice.By the requirement of seedling-throwing technology, each seedling dish alms bowl need evenly be broadcast the grain into conventional japonica rice 3-4, both can cultivate strong sprout, can save seedling dish and seed again.

In order to realize above-mentioned target, existing multiple at present seeder comes out.Precision quantitative seed drill (patent No. 962508780) as the production of Songyuan City, Jilin Province milky way Samsung paddy rice precision seeding machine Co., Ltd; Zhu of Agricultural University Of Southwest is from all designs, and the universal precision quantitative seed drill of polished round-grained nonglutinous rice and polished long-grained nonglutinous rice (application number 98214333.8) that Xinyi Package-Material Co., Ltd., Shanghai produces can both reach the standard of above-mentioned Precision Seeding.But the former volume is big, and the single hole simple grain broadcasts, and does not have kind of a box design, not only cost height, and inconvenient operation; The latter takes the two grain designs of diplopore, and it shows as, and volume is little, precision is high, easy to operate, and especially when broadcasting hybrid rice, each circulation can promptly be broadcast full seedling dish with 2 standards.But its needs two holes to broadcast seedling alms bowl of people in the lump when broadcasting conventional japonica rice just can reach standard about 4, and a circulation can only be broadcast half of full seedling dish, and its speed seems not ideal enough.

The purpose of this utility model is the precision quantitative seed drill that the special use of a kind of improved conventional japonica rice rice transplanting will be provided, and makes it both to have realized on this precision seeding machine that a circulation broadcasts full seedling dish, reaches each seedling alms bowl again and broadcasts standard into 3-4 grain conventional japonica rice.

The purpose of this utility model is achieved in that the hole shape of the amount kind plate of the universal precision quantitative seed drill of polished round-grained nonglutinous rice and polished long-grained nonglutinous rice that Xinyi Package-Material Co., Ltd., Shanghai is produced is improved with size: widened into one arcly in the outside of every pair of original amount kind of square hole, the novel species hole of its formation is formed by the arcuate apertures common combination of original square hole and increase.The string of arcuate apertures is the long limit in the square hole outside, and the bow height can change between 1.5-3.5mm because of seeder specification difference, and promptly the height in the new hole of being made up of arcuate apertures and square hole is 7.5-9.5mm.

Because each novel species hole has all increased certain arc area, thereby make each original 2 of square hole amount kind become present novel species hole amount kind of 3-4 grain.When broadcasting conventional japonica rice, any seed that measure in the hole in each group diplopore is broadcast the standard that can reach the 3-4 grain into a seedling alms bowl, needn't need two holes to broadcast in the lump in the seedling alms bowl as improvement is preceding.During operation, can once sieve and plant quantitatively, the double left and right sides diverse location of broadcasting into traverse seedling dish makes a circulation broadcast full seedling dish, reaches the purpose that improves speed of drilling.Simultaneously, because the area that the novel species hole increases is arc, the periphery is an arc, has also avoided expanding the problem of the amount kind plate intensity reduction that square hole brought effectively.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

The details and the working condition of the used precision seeding machine of conventional japonica rice rice transplanting that foundation the utility model proposes are described below in conjunction with Fig. 1.

This seeder comprises chassis (1), amount kind of plate (2) and press strip (3), and amount kind of a plate (2) places on the chassis (1), and its both sides are compressed by press strip (3).Be making up the property between reinforcement amount kind plate (2) and chassis (1), many slide-and-lock screws (4) in the middle also evenly distribute.One end of amount kind of plate is established a grade paddy sheet (5), and according to the diplopore (6) of the distribution respective production equal number of seedling alms bowl, each single hole in the diplopore is made up of original square hole (7) and arcuate apertures (8) two parts area of widening on the plate.According to the distribution of every group of diplopore (6) on amount kind of the plate, the single hole (seed leaking hole) of equal number is set on chassis (1) accordingly.When this seeder uses, kind of a plate at first slides, make all plant the hole and be in closed state, plant quantitatively through sieve, make every hole enter 3-4 grain seed, and then plant a plate, successively broadcast two ends, the left and right sides at twice into traverse seedling dish to slip in the other direction, thereby realize that a circulation broadcasts full seedling dish, and reach each seedling alms bowl and broadcast purpose into 3-4 grain conventional japonica rice seed.

Claims

1. conventional japonica rice seedling-throwing precision seeder, it is coincided by the chassis (1) of the amount kind plate (2) on top and bottom and forms, be connected with locking screw (4) with press strip (3) between two-layer, have some groups of diplopores (6) on the amount of the it is characterized in that kind plate (2), have the single hole of equal number on the chassis accordingly.

2. seeder according to claim 1, on the amount of the it is characterized in that kind plate (2) each single hole of the diplopore of opening (6) form by square (7) and arc (8) two parts area.
