Abstract

The utility model relates to the field of an agricultural implement, particularly a direct seeding-machine for rape seed, soy bean, maize, etc. The utility model is composed of seed bins, a seed clamping sheet, seed dividing holes, seed dropping pushing needles, an eccentric shaft, a branch tube, a needle pushing cylinder, etc. The utility model is characterized in that a plurality of seed dropping pushing needles are fixedly connected with the eccentric shaft; the seed dividing holes corresponding to the seed dropping pushing needles are arranged on the needle control cylinder along the radial direction; a seed clamping sheet and the seed bin are arranged on the upper part of the eccentric shaft. The branch tube is arranged under the eccentric shaft. The seed bins are fixedly connected with both ends of the eccentric shaft through screw bolts. The utility model is a direct seeding-machine with small volume, reasonable design and efficiency increase by many times.

Description

Seed direct sowing machine

The utility model relates to the farm machinery field, is to be used for a kind of seed direct sowing machine that planting seeds such as vegetable seed, soybean, corn are used.

As everyone knows, the modernized farm machinery of large-scale sower, grain header class have been popularized for many years, and that small-sized seed sowing machine tends to again is multi-functional, the slimline direction develops.But the peasant of quite a few also owes high farm implements in farm work by work efficiency habitually.This explanation sophisticated equipment exists certain " distance " with application.

The purpose of this utility model is, provides a kind of structure comparatively easy seed direct sowing machine to this area, makes its cost lower, and has the function of alternative by artificial seeding, shortening " distance ", with the low problem of solution work efficiency.

Above-mentioned purpose is achieved in that the operation principle of the eccentric throw that produces in its application eccentric shaft rotation, the seed dropping top needle that connects on the eccentric shaft is matched with seed-dividing hole in the needle controling tube, and in seed-dividing hole, leave " position " of a seed, when the moving circle of eccentric shaft revolution, seed is promptly ejected needle controling tube by seed dropping top needle, broadcasts into the field through a minute line pipe.The quantity of revolution sowing is to decide according to the seed dropping top needle quantity on the eccentric shaft, and the seed dropping top needle that this machine is set is 96, promptly once sows 96, thereby realizes improving sowing work efficiency several times.

Description of drawings:

Fig. 1 is a seed direct sowing machine member schematic layout pattern;

Fig. 2 is the organigram of seed direct sowing machine;

Sequence number among the figure: 1, shell stator, 2, bolt, 3, fixed mount, 4, card seed sheet, 5, seed-dividing hole, 6, seed dropping top needle, 7, driven sprocket, 8, eccentric shaft, 9, driving chain, 10, screw, 11, divide line pipe, 12, drive sprocket, 13, driving shaft 14, bearing block, 15, needle controling tube, 16, seed cabin, 17, shaft-cup.

Referring now to above schematic diagram, its feature is further described: seed direct sowing machine is made of shell stator, fixed mount, seed cabin, card seed sheet, seed-dividing hole, seed dropping top needle, driven sprocket, eccentric shaft, driving chain, branch line pipe, driving shaft, needle controling tube etc., it is characterized in that: be connected and fixed some seed dropping top needles 6 on the eccentric shaft 8, radially offering and the corresponding seed-dividing hole 5 of seed dropping top needle of needle controling tube 15, this eccentric shaft is to be fastened on the fixed mount 3 of bearing block 14 with rolling; Be provided with card seed sheet 4, seed cabin 16 on the top of eccentric shaft 8; Be provided with branch line pipe 11 in the bottom of eccentric shaft 8; Seed cabin 16 is to be connected by bolt 2, is fixed on the two ends of eccentric shaft 8.The seed-dividing hole that needle controling tube 15 is radially offered is a through hole, and the degree of depth in this hole is exactly the wall thickness of needle controling tube, and the eccentric throw of its wall thickness and eccentric shaft 8 is slightly darker.

Operation principle: rotate by manpower or power drive driving shaft 13, and drive drive sprocket 12, driving chain 9, driven sprocket 7, eccentric shaft 8 and rotate, fixing 16 seed dropping top needles 6 in a seed cabin 16 on the eccentric shaft, its diameter is φ 1.6mm, the seed-dividing hole of radially offering 5 diameters of needle controling tube are φ 2mm, eccentric shaft and needle controling tube rotate in the same way, and the gap of seed dropping top needle in seed-dividing hole is 0.4mm.The maximum eccentricity that eccentric shaft rotates a circle is 1.6, and the wall thickness of needle controling tube is 5mm, and the seed dropping top needle on the eccentric shaft moves between the seed-dividing hole wall thickness in needle controling tube all the time.In other words, the seed dropping top needle stroke is 4mm, and the degree of depth of seed-dividing hole is 5mm, and it rotates a circle by seed cabin, when card seed sheet enters seed-dividing hole when one, and seed dropping top needle just in time ejects this seed, is flowed out by minute line pipe, broadcasts into the field.Another grain seed falls into seed-dividing hole when rotating second circle, goes round and begins again that this ejects, falls into, the rotating operation program again, is finally discharged by minute line pipe, broadcasts into the field.The eccentric shaft of each seed cabin of seed direct sowing machine is provided with 16 uniform seed dropping top needles, and 6 seed cabins are provided with 96 seed dropping top needles altogether, and the wheel on the driving shaft (omit and draw) rotates a circle and promptly sows 96 seeds.Impartial because of quantity, the distance of each sowing, can improve about 500 times of work efficiency than single by artificial seeding.Its particle of different seeds is different, then need only adjust corresponding eccentric throw, and sowing can be finished in the aperture that seed-dividing hole matches on seed dropping top needle, the drilling needle controling tube.

This seed direct sowing machine, neither multicast is much planted again, accomplishes without any confusion, can sow in the nonirrigated farmland, can sow in the paddy field again.Be that present volume is less, the comparatively rational a kind of seed-sowing machine of structure design has certain application value.
