technical field

The invention relates to agricultural machinery, in particular to a pesticide seed dressing machine, which is specially used for uniformly stirring seeds and pesticides before sowing in farmland.

Background technique

When farmers sow, in order to prevent the seeds from being damaged by underground pests and bacteria, they must use pesticides to dress the seeds. Some are manual seed dressing, that is, sprinkle the medicinal liquid on the seeds and mix them well with a shovel, but it takes a lot of work; some use cement mixers or dough mixers for mechanical seed dressing, and put the seeds into the machine first. , then sprinkle the liquid medicine on the seeds, and finally stir with the metal utensils that come with the machine. At this time, the radicle and seed coat that have absorbed water are easily damaged, which greatly reduces the germination rate. At the same time, this machine The stirring method is laborious and unsafe. Therefore, the requirements of modern farmers cannot be met.

Detailed ways

The pesticide seed dressing machine of the present invention comprises a feed bin 1 with a weight scale 16, a liquid medicine container 2 with a capacity scale 17, a fan 3 and an agitator 4; the fan 3 is connected to the beginning of the main air duct 6 through an air pipe 5, The end of the main air duct is horizontally connected to the agitator 4; the silo 1 is connected to the beginning of the main air duct through the material pipe 7, and there is a raw material valve 8 on the material pipe; the lower end of the liquid medicine container 2 is connected to the end of the main air duct through the medicine pipe 9, The beginning of the medicine tube is provided with a straight-through switch 10, and the end of the medicine tube is provided with a micro-adjustment switch 11; The feed opening is connected to the end of the main air duct 6 along the tangential direction of the cylinder, an upward air outlet 12 is provided in the middle of the cylinder, and a discharge outlet 13 is provided at the lower end of the cone. Above the feed inlet of the agitator, there is a homogenizing tongue 14 that disperses the seeds and the medicinal solution. A receiving cabinet 18 is provided below the discharge port. The cylinder of the agitator is provided with vent holes 19 . The liquid medicine container 2 has a cover.

This kind of pesticide seed dressing machine is composed of fan, hopper with quantitative scale, hopper valve, material pipe, air pipe, agitator, liquid medicine container, medicine pipe, medicine liquid straight-through switch, medicine liquid micro-adjustment switch, etc. .

The fan is the power source of the seed dressing machine, which can generate a certain amount of air volume, and the wind drives a bunch of raw materials into the mixer through the air duct.

The silo with a certain capacity is marked with a certain scale. When the seeds are placed in the silo, the amount of seeds entering the agitator per unit time can be visually seen. The raw materials pass through the raw material valve and enter the material pipe. The pipe enters the main air duct and enters the agitator downwind.

The agitator is composed of a cylinder of a certain size and a cone with a certain taper. The cylinder is provided with a feed pipe (main air duct) along a point tangent, an air outlet is provided in the middle (that is, directly above), and a discharge port is provided at the small end of the cone (that is, directly below).

A certain amount of medicinal liquid is placed in the medicinal liquid container, and a certain amount of scale is marked on the container, so that the amount of medicinal liquid entering the agitator per unit time can be visually seen. The liquid medicine enters the agitator through the medicine pipe. There is a straight-through switch under the liquid medicine container, and a micro-adjustment switch near the agitator along the direction of the flow tube. When it is found that the liquid medicine does not enter the agitator as required, it can be adjusted at any time.

The liquid medicine inlet is installed on the feeding pipe (main air duct), close to the feeding port.

The liquid medicine container is marked with an accurate capacity scale, which can intuitively find the amount of medicine entering the agitator per unit time, and has a fine-tuning switch, which can ensure a more accurate dosage of the liquid medicine. The straight-through switch is always on in the working state, and when there is a problem with the fine-tuning switch, the straight-through switch can be turned off to repair the fine-tuning switch.

The seeds are in a silo with a certain capacity, and form a bunch of raw materials through the raw material valve, and enter the mixer through the material pipe and the main air duct. There is a certain capacity scale in the silo, which can ensure that the required amount of seeds enters the agitator.

The feed port of the agitator is driven by wind to bring seeds and liquid medicine into the agitator. When the medicinal liquid first enters, it is vertically downward, and after entering the mouth, it advances horizontally under the action of the wind. When the liquid advances, it is blocked by the leveling tongue, and the liquid medicine is rapidly dispersed along the edge of the leveling tongue, and the dispersed liquid medicine is taken away by a bunch of advancing raw materials until it reaches the inner surface of the cylinder of the agitator. Because the feed inlet is located on a point tangent to the cylinder, and the drug inlet is near the feed inlet, the impact force on the rapidly wet raw material is extremely small, because when the raw material enters the agitator, it encounters a curved surface, At this time, the raw material quickly spirals along the inner surface of the cylinder under the action of inertia and gravity, so the radicle and epidermis of the seed are not easily damaged and are evenly coated with the liquid medicine. Separation of medicinal species.

The seeds do spiral motion on the inner surface of the cylinder. After a certain period of time, the seeds reach the joint between the inner surface of the cylinder and the inner surface of the cone, and their rotation (tumbling) direction changes. There is almost no residual medicinal solution (that is, no liquid droplets, and the medicinal solution is all mixed on the seeds). The seeds flow out along the outlet, and the seed dressing is completed.
