Description
Technical Field
The utility model relates to the technical field of grain cleaning equipment, in particular to a discharging hopper for grain cleaning equipment.
Background
After the grains are harvested, impurities such as straws, spike heads and dust need to be removed through cleaning, the grains are generally screened by adopting cleaning equipment, however, the screened grains are often mixed with the impurities, other equipment needs to be adopted for further cleaning, and the labor and the time are wasted.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a blanking hopper for grain cleaning equipment.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a lower hopper for grain cleaning equipment, includes the lower hopper of being connected with grain cleaning equipment's grain discharging channel, lower hopper is the funnel that the cross-section is the rectangle, two opposite flank of lower hopper are provided with the aspiration channel, the outer end intercommunication of aspiration channel has the air exhauster, two other opposite flank of lower hopper are provided with the air-supply line.
Furthermore, the aspiration channel comprises a special-shaped inclined tube communicated with the discharging hopper and a vertical tube connected with the special-shaped inclined tube and the exhaust fan.
Further, the air intake of air-supply line is provided with the air transfer valve, the air transfer valve including set up in opening of air intake have the board of sealing of a plurality of fan-shaped hole and with seal the board and rotate the regulating plate of connecting, the regulating plate be provided with seal the fan-shaped hole that the board equals quantity.
Further, the air outlet of the exhaust fan is communicated to the bottom of the water tank through a pipeline.
The utility model has the beneficial effects that: the utility model provides a lower hopper for grain cleaning equipment, its includes the lower hopper of being connected with grain cleaning equipment's grain discharging channel, the hopper is the funnel that the cross-section is the rectangle down, two opposite flank of hopper are provided with the aspiration channel down, the outer end intercommunication of aspiration channel has the air exhauster, two other opposite flank of hopper are provided with the air-supply line down. According to the utility model, the winnowing device is arranged at the feed opening of the grain cleaning equipment, so that impurities such as dust in the grains are sucked away, the effect of further cleaning the grains is achieved, the subsequent cleaning operation is omitted, and the time and the labor are saved.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, which are not intended to limit the scope of the utility model.
As shown in fig. 1, the blanking hopper for grain cleaning equipment of this embodiment includes blanking hopper 1 connected with grain discharging channel of grain cleaning equipment, blanking hopper 1 is a funnel with a rectangular cross section, two opposite side surfaces of blanking hopper 1 are provided with air suction pipes 2, the outer end of air suction pipe 2 is communicated with exhaust fan 3, and the other two opposite side surfaces of blanking hopper 1 are provided with air inlet pipes 4. The utility model further improves the existing grain cleaning equipment, namely, a winnowing device is arranged at the grain discharging hopper, and impurities such as dust and the like remained in the grains are sucked away by utilizing the negative pressure formed by the exhaust fan 3, thereby achieving the effect of further cleaning the grains.
The utility model is mainly used for winnowing of grains such as rice, wheat, soybean, corn and the like, and the specific gravity of impurities such as dust and the like is smaller than that of the grains, so that the impurities with smaller specific gravity are sucked away when the grains fall along the blanking hopper, and the grains can be left. Here, can adopt inverter motor control the rotational speed of air exhauster 3 to adjust the negative pressure intensity, also can the air intake of air-supply line 4 is provided with air regulating valve 5, air regulating valve 5 including set up in opening of air intake have a plurality of fan-shaped hole seal board 51 and with seal board 51 and rotate the regulating plate 52 of being connected, regulating plate 52 be provided with seal board 51 equals the fan-shaped hole of quantity, thereby the method of the amount of wind of adjusting the air intake is adjusted negative pressure in the air-suction line.
When the grain falls, the grain possibly enters the air suction pipe 2, therefore, in order to ensure that the grain entering the air suction pipe 2 automatically falls and cannot be sucked away, the air suction pipe 2 consists of a special-shaped inclined pipe 21 communicated with the blanking hopper 1 and a vertical pipe 22 connecting the special-shaped inclined pipe 21 and the exhaust fan 3.
In addition, the air outlet of the exhaust fan 3 is communicated to the bottom of the water tank through a pipeline, so that the air exhausted by the exhaust fan 3 is filtered, and the dust pollution is reduced.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
