Abstract

The utility model relates to a paddy rice direct seeding device which is capable of being slung over shoulders. The paddy rice direct seeding device is a novel seeding appliance. The utility model is characterized in that the paddy rice direct seeding device which discharges and transfers the seeds by means of the air stream has the advantages of small external shape, simple configuration, practicality and energy saving, the utility model is composed of a funnel-shaped seed box, a seeding quantity adjusting plate, an operating handle, a seeding pipe, a centrifugal hand blower, a draught fan air discharge pipe, a constricted diameter changing pipe and a seed transferring pipe. The utility model has the working process that the seeds in the seed box flow down by gravity, pass through the seeding pipe and the seeding quantity adjusting plate and fall into the mud, and then the seeds are automatically covered with the soil. The direct seeding device is used for the direct seeding of the paddy rice, and compared with the manual seedling raising, the manual seedling pulling and the manual seedling transplanting, the utility model raises the work efficiency by 4 to 6 times.

Description

Rice direct-seeding device capable of being slung over shoulder

The utility model is a kind of new type sowing device, is application technical research.Regional preferably in the water conservancy condition, rice direct-seeding saves time than rice transplanting saving of labor, reduces operating cost, and per unit area yield is compared no significant difference with rice transplanting.Annotate 1.

China's rice cropping is with a long history, and traditional cultivation method is: seedling, pull up seedlings rice transplanting, field management, results, processes such as threshing.Every operation consumption labour is many, and labour intensity is big.Particularly rice transplantation by hand is had a pain in the back, and labor productivity is low.Rice transplanter has developed into certain level both at home and abroad in recent years.But complex structure, the cost height, the peasant farmer is difficult to buy, and the user also will buy seedling collector except that buying rice transplanter, seedling equipment etc., a complete set of equipment cost is higher, and under present condition, China is difficult to large scale application.

The utility model purpose is for China south rice district provides a kind of simple in structure, reliable operation, and seeding quality is good, and the hanging rice direct-seeding utensil of small-sized shoulder solves difficulty in the rice cultivating technique.

The purpose of this utility model is achieved in that the characteristics little according to current China peasant farmer scale of operation, that the plot is little, designs this small-sizedly, simple in structure, practical, energy-conservation, uses easy to operate air-flow seeding formula rice direct-seeding utensil.It is by 1. funnel-form seed-box; 2. the amount of broadcasting adjustable plate and operating grip; 3. the pipe of sowing; 4. centrifugal hand blower; 5. blower fan discharge pipe; 6. waisting shape reducer pipe; 7. composition such as grain tube.The course of work of its sowing is: 3. through the amount of broadcasting adjustable plate 2. the 1. interior seed of seed-box flows into by gravity sows pipe, and when the amount of broadcasting adjustable plate was opened, seed just flowed in the waist of waisting shape reducer pipe.The speed of air-flow is big herein, and seed is blowed out grain tube outlet 7., and seed just is sprinkling upon certain depth place in the mud in field, and earthing does not need covering device and plough automatically, has simplified the structure of this line-sower, cuts down the consumption of energy and cost.The utility model is mainly used in the sowing in the field paddy rice, per hour broadcasts 2-3 mu, than artificial seedling, pull up seedlings, and rice transplanting, work efficiency improves 3-5 doubly.And sowing evenly.During sowing line-sower shoulder is hung over the front, one man operation, the right hand shakes fan blower, treat that air-flow reaches certain speed after, left hand is slowly opened the amount of broadcasting adjustable plate, is transferred to correct position.The people is even, and the step advances, and seed can be broadcasted sowing down on the farm equably.Finish the rice direct-seeding task.

The utility model compared with prior art, its advantage is:

1, compare with the traditional type sower, structure is simplified greatly.It saves plough, covering device, frame, transmission device etc.Capable of reducing energy consumption, thus operating cost 40-50% reduced.

2, adopt the utility model, one man operation per hour can be sowed 2-3 mu by direct seading rice, than artificial seedling, pull up seedlings, and rice transplanting, work efficiency can improve 3-5 doubly, and per unit area yield is compared no significant difference with rice transplanting.

3, with the large and medium-sized seedling of purchase, pull up seedlings, rice transplanting equipment is compared, and the equipment investment expense reduces 8-9 doubly, thereby the reduction operating cost only is the former 1/10.

Concrete structure of the present utility model is described with reference to the accompanying drawings as follows:

1. number in the figure is the funnel-form seed-box, 8.5 kilograms of seed rice of capacity, and 45 ° at box plate inclination angle at the middle part of seed-box base plate inclined plane one side, has " one " font groove along the inclined plane; 2. be the amount of broadcasting adjustable plate and operating grip, the amount of broadcasting adjustable plate is the sliver shape, left end is the garden arc, right-hand member flat line two lead angle, the amount of broadcasting adjustable plate is along leaning against on the inclined plane of seed-box base plate during installation, its operating grip can drive adjustable plate in " one " font groove on seed-box base plate inclined plane upper and lower mobile, or be fixed on some positions, the control amount of sowing; 3. be the pipe of sowing, the pipe upper port is welded in funnel mouth place of funnel-form seed-box.Infratubal port is welded in the waist garden Kong Chu of waisting shape reducer pipe, constitutes circulation road under the seed; 4. be centrifugal hand blower, gearratio 1:36, per minute hand 40 changes, about 1600 rev/mins of draught fan impeller rotating speeds, the air velocity of generation can satisfy the sowing requirement; 5. be the blower fan discharge pipe, 44 millimeters of external diameter φ; 6. be waisting shape reducer pipe, pipe right-hand member and the socket of blower fan air outlet tube mouth are tight; Pipe left end and grain tube socket.Above the pipe waist, have hole, a garden, the lower end of being inserted in the pipe of sowing, seam then.Constitute the passage of airflow blow seed, because pass through the air-flow speedup here, the requirement that blows seed is satisfied in supercharging; 7. be grain tube, right-hand member is inserted in the left end of waisting shape reducer pipe.Its effect is to borrow air velocity and pressure, and seed is transferred out, and is sprinkling upon the field equably.

Annotate 1. with reference to 89 years the 5th volumes of Transactions of the Chinese Society of Agricultural Engineering, 1 phase 76-80 page or leaf.
