The rice grain seeder has the advantages of high seeding uniformity, small overall size, light weight, low manufacturing cost and simple and convenient operation.

Description

Paddy rice particle sower

Technical field

The utility model relates to a kind of farm machinery, specifically is a kind of paddy rice particle sower that utilizes the cylinder ordering.

Background technology

Traditional rice growing is that rice paddy seed is sowed on rice seedling bed or seedling dish, and its sowing labour intensity is big, and the seed density of sowing is extremely inhomogeneous, and density differs greatly, and is unfavorable for the equilibrium growth of rice shoot, also wastes seed and seedling ground, seedling dish.At present, use in rice growing machinery field and more be many and do not have the big-and-middle-sized sowers of ordering, because these sowers do not have ordering, volume is bigger, its seed uniformity of sowing is not high, the rice shoot that grows is inhomogeneous, be unfavorable for the operation of later stage rice transplanting machinery, volume is great again, can't be in the field sowing operation.

The utility model content

Technical problem to be solved in the utility model provides a kind of high paddy rice particle sower of the seed uniformity of sowing.

The utility model solves the problems of the technologies described above with following technical scheme: cylindrical drum, direct current generator and coaxial speed change gear wheel and change speed pinion are installed in the outside framework of the utility model paddy rice particle sower, the outer surface of cylindrical drum is evenly equipped with the particle open-work, on the connecting axle of one end gear is installed, the connecting axle of the other end has the seed dispensing port, and the seed dispensing port has seal closure; The motor gear that is installed on the direct current generator output shaft is meshed with the speed change gear wheel, and change speed pinion is meshed with gear on the cylinder connecting axle; There is the loam cake that is connected with outside framework the top of described outside framework, and the below connects the seed setting limit that changes and decide funnel and gear-box lower cover, and the both sides, front and back of outside framework are equipped with the connecting rod with the handgrip flexible connection.

The shape of described particle open-work is identical with the rice paddy seed grain shape, is oval elongated hole.

The connecting rod top of described outside framework rear side is provided with the pin joint jack that can regulate the handgrip gradient.

Use the utility model to carry out the rice paddy seed sowing, can make the seed uniform sequencing degree height of sowing, help cultivating the balanced growth of rice shoot, be convenient to later stage rice transplanting mechanical work; And the utility model sower volume is little, in light weight, cost is low, use is easy and simple to handle, can be applicable to ground, field, seedling dish upper seeding wheel.

Description of drawings

Fig. 1 is the structural representation of the utility model paddy rice particle sower.

Fig. 2 is the oblique schematic top plan view after Fig. 1 takes off loam cake.

Fig. 3 is the structural representation after the cylindrical drum partial cutaway among Fig. 1.

Fig. 4 is that the setting limit that changes of the seed among Fig. 1 is decided structural representation after the funnel partial cutaway.

Among the figure: outside framework 1, cylindrical drum 2, particle open-work 3, seed dispensing port 4, seal closure 5, gear 6, change speed pinion 7, motor 8, motor gear 9, attaching plug 10, the seed setting limit that changes is decided funnel 11, motor switch 12, loam cake 13, gear-box lower cover 14, braces 15, handgrip 16, preceding lateral connector bar 17, back lateral connector bar 18, connecting axle 19, speed change gear wheel 20, pin joint jack 21.

Embodiment

As shown in drawings, cylindrical drum 2, direct current generator 8 and coaxial speed change gear wheel 20 and change speed pinion 7 are installed in the outside framework 1 of the utility model paddy rice particle sower, the outer surface of cylindrical drum 2 is evenly equipped with particle open-work 3, the shape of particle open-work 3 is identical with the rice paddy seed grain shape, is oval elongated hole; On the connecting axle 19 of cylindrical drum 2 one ends gear 6 is installed, the connecting axle of the other end has seed dispensing port 4, and seed dispensing port 4 is provided with seal closure 5; The motor gear 9 that is installed on the output shaft of direct current generator 5 is meshed with speed change gear wheel 20, and change speed pinion 7 is meshed with gear 6 on the cylinder connecting axle; There is the loam cake 13 that is connected with outside framework 1 top of outside framework 1, the below of outside framework 1 is connected with the seed setting limit that changes and decides funnel 11 and gear-box lower cover 14, the installed in front of outside framework 1 has preceding lateral connector bar 17, rear side is equipped with back lateral connector bar 18, preceding lateral connector bar 17 and back lateral connector bar 18 all flexibly connect by latch and handgrip 16, and the top of back lateral connector bar 18 is provided with the pin joint jack 21 that can regulate the handgrip gradient.

Operating personnel use the utility model sower for convenience, can connect braces 15 on outside framework 1, and on handgrip 16 motor switch 12 are installed.

Before operation the utility model sower, need join 12 volts of storage batterys, and connect storage battery by attaching plug 10.Earlier rice paddy seed is put into cylindrical drum 2 from seed dispensing port 4 before using, and build seal closure 5, by braces 15 the utility model sower is hung on one's body the operating personnel then, starter motor switch 12, making motor gear 9 drive speed change gear wheel 20 rotates, change speed pinion 7 driven gears 6 coaxial with speed change gear wheel 20 rotate, thereby cylinder 2 is rotated with the rotating speed after the speed change, make the rice paddy seed in the cylinder 2 come out and decide funnel 11 and fall into sowing on the ground simultaneously, thereby realize that the higher seed ordering of the uniformity sows through the seed setting limit that changes from particle open-work 3.
