An actuating mechanism is arranged outside the measuring chamber for displacing the measuring chamber. The combined type measuring packing scale main feed device of the utility model can enhance measuring accuracy and speed. The combined type measuring packing scale main feed device of the utility model is applicable for measuring packing granular and powdered materials, especially agronomic crop seeds.

Description

Compound type metering packing scale is slightly fed device

Technical field

The utility model relates to a kind of drawing-in device of measurement instrument.Specifically, be that the compound type metering packing scale that is used for graininess, powder material are carried out metering packing is slightly fed device, be particularly useful for metering packing to crop seeds.

Background technology

At present, be used for that the method that graininess, powder material measure is had two kinds.A kind of is the volumetry metering, and another kind is the weight method metering.The metering of employing volumetry is though speed is fast, because this method is to fill material with the container of a fixed volume to measure.When the proportion of material different or used container adorn the depth not simultaneously, will cause very mistake.Therefore, there are metering inaccuracy, problem that error is big.Though and weight method is measured the precision height, because this method realizes measuring by continuous feeding material, material can only slowly be sent in temporary storing bin, can not reach the thick quantitative values of feeding quickly.Therefore, this method is subjected to the restriction of rate of feeding, and metering speed is not high.

Summary of the invention

The purpose of this utility model is to provide a kind of compound type metering packing scale slightly to feed device.Utilize this device can improve measuring accuracy and speed.

Above-mentioned purpose of the present utility model is realized by following technical solution:

Compound type metering packing scale of the present utility model is slightly fed device, comprises temporary storing bin, and its constructional feature is that upper cover plate is arranged at this temporary storing bin bottom, and the capacity storehouse is arranged under the upper cover plate, and capacity has lower cover under the storehouse.Inlet point and discharging opening are arranged respectively on the upper and lower cover plate.Capacity has longitudinal hole on the storehouse, and the size of this through hole is identical with inlet point and discharging opening on the upper and lower cover plate.Wherein, inlet point on the upper cover plate and the discharging opening position on the lower cover are staggered and are provided with on level, so that the capacity storehouse is when producing displacement under external force, the longitudinal hole on it can alternately be connected with inlet point and the discharging opening on the upper and lower cover plate.

The outside, capacity storehouse is useful on and makes it produce the transmission device of displacement, and this transmission device contains motor, on the output shaft of motor wheel is arranged, and a side of wheel has eccentric orfice.On one sidewall in capacity storehouse axle bed is arranged, between the eccentric orfice on this axle bed and the wheel connecting rod is arranged, the two ends of this connecting rod are moving type by pin respectively and are hinged on the axle bed and the eccentric orfice place.

Adopt such scheme, have the following advantages:

Because compound type metering packing scale of the present utility model is slightly fed device and is included temporary storing bin, be provided with the capacity storehouse under the temporary storing bin, the upper and lower side in capacity storehouse has cover plate up and down respectively, inlet point and discharging opening are arranged respectively on the cover plate up and down, and this inlet point and discharging opening are staggered and are provided with, the capacity storehouse can produce displacement under the effect of transmission device.When its be moved to its longitudinal hole corresponding with the inlet point of upper cover plate, with lower cover on discharging opening when cutting off mutually, the material that temporary storing bin communicates with the capacity storehouse and temporary storing bin is interior can fall in the capacity storehouse.When the material in the capacity storehouse reached requirement, the capacity storehouse can produce the displacement of a through hole again around its center of circle under the effect of transmission device.At this moment, the longitudinal hole on the capacity storehouse corresponding with the discharging opening on the lower cover, with upper cover plate on inlet point cut off mutually.Like this, utilize the capacity storehouse in the left-right rotation between cover plate up and down, realize its with upper cover plate on inlet point and the open and close between the discharging opening on the lower cover, and then reach control charge and blowing how much.Adopt the thick device of feeding of the present utility model, improved thick precision and the speed of feeding greatly.Thereby can improve the measuring accuracy and the speed of complete machine greatly.

The specific embodiment

As shown in Figure 1 and Figure 2, compound type metering packing scale of the present utility model is slightly fed device and is comprised a temporary storing bin 1, and upper cover plate 2 is arranged at the bottom of this temporary storing bin, and capacity storehouse 3 is arranged under the upper cover plate 2, and lower cover 4 is arranged under the capacity storehouse 3.Be processed with an inlet point and discharging opening on upper cover plate 2 and the lower cover 4 respectively, also have a longitudinal hole on the capacity storehouse 3.Longitudinal hole on inlet point on upper cover plate 2 and the lower cover 4, discharging opening and the capacity storehouse 3 is oblong.Discharging opening on inlet point on the upper cover plate 2 and the lower cover 4 is staggered and is provided with on level attitude, promptly the inlet point on the upper cover plate 2 is opened in the central and be corresponding with the longitudinal hole on the capacity storehouse 3.And the longitudinal hole on the capacity storehouse 3 is opened in the one side, and with lower cover 4 on the stagger position in a hole of discharging opening.Like this, when when filling with substance in capacity storehouse 3, the inlet point on the upper cover plate 2 is corresponding with the longitudinal hole on the capacity storehouse 3, and cuts off mutually with discharging opening on the lower cover 4; When the material in the capacity storehouse 3 is unloaded, can make capacity storehouse 3 produce displacement by means of the effect of external force, make the longitudinal hole on the capacity storehouse 3 corresponding with the discharging opening on the lower cover 4.3 outsides, capacity storehouse are equipped with and can make it produce the transmission device of displacement, and this transmission device comprises motor 5, is fixed with wheel 6 on the output shaft of motor 5, and center one side of wheel 6 has eccentric orfice.On one sidewall in capacity storehouse 3 axle bed 8 is installed, 6 on this axle bed and wheel are provided with connecting rod 7.The two ends of connecting rod 7 are by pin respectively that moving type is hinged on the axle bed 8 and the eccentric orfice place of wheel 6.During work, the transmission device of being made up of motor 5, wheel 6, connecting rod 7 drives capacity storehouse 3, makes it produce displacement, thus the longitudinal hole on the capacity of the realization storehouse 3 respectively with upper cover plate 2 and lower cover 4 on inlet point and discharging opening be communicated with or cut off.

Fig. 3, Fig. 4 are the another kind of forms that compound type metering packing scale of the present utility model is slightly fed device, it is fan-shaped that itself and the foregoing description difference are that charging and discharging mouth on upper cover plate 2, the lower cover 4 and the longitudinal hole on the capacity storehouse 3 are, and quantity all equates with size.All have centre hole on the capacity storehouse 3 with on upper cover plate 2, the lower cover 4, be installed together by means of axis of revolution 9 between the three.Wherein 3 in axis of revolution 9 and capacity storehouse fix, and then are movable with

upper cover plate

2 and 4 of lower covers and cooperate.During work, capacity storehouse 3 produces the displacement of a cw or a through hole of conter clockwise under the effect of transmission device, just can make inlet point on longitudinal hole and the upper cover plate 2 on the capacity storehouse 3 or the discharging opening on the lower cover 4 be communicated with or cut off.
