Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-4, the utility model discloses an accurate dose feeder, including unloading pipe 1 in the embodiment of the utility model, include through connecting axle 10 with 1 inside wall fixed connection's of unloading pipe measurement storage silo 2, locate measurement storage silo 2 below and adjustable its with interval bottom plate 3 between the measurement storage silo 2 and locate measurement storage silo 2 with between the bottom plate 3 and through its reciprocating motion of cylinder 4 control and with the material pushing module 5 that the partial area of material in the measurement storage silo 2 left off.

In the embodiment of the present invention, the material pushing module 5 includes a connecting rod 50, two fixed connection rods, which control the reciprocating motion of the connecting rod 50 through the cylinder 4, and a ring-shaped material spoon 51 which is located on the connecting rod 50, between the metering storage bin 2 and the bottom plate 3 and is adapted to the metering storage bin caliber L1.

The utility model discloses in the embodiment, measurement storage silo 2 include through connecting axle 10 with blanking pipe 1 inside wall fixed connection and shape are the storehouse body 20 of "cylindrical" and cavity setting, locate the opening 21 of the storehouse body 20 top and the storehouse body 20 bottom and install in the shock attenuation post 22 of the storehouse body 20 lateral wall, wherein, the sunken cavity 23 that is equipped with in bottom of each shock attenuation post 22, bottom plate 3 includes that the interval is located the plate body 30 of the storehouse body 20 below and install in the spliced pole 31 that the plate body 30 circumference outside was followed, wherein, the cavity bottom of cavity 23 through compression spring 24 with spliced pole 31 fixed connection.

In the embodiment of the present invention, there may be 2 shock absorbing columns 22.

In the embodiment of the present invention, the annular material spoon 51 is shaped as an inverted circular truncated cone.

In the embodiment of the present invention, a sealing plate 51a is fixedly connected between the outer side walls of the adjacent annular material scoops 51.

By adopting the technical scheme: when the materials pass through the blanking pipe for the first time, the metering storage bin is filled with the materials at the same time, after the rough adding of the materials is finished, when a system requires fine adjustment action, the air cylinder drives the annular material spoon to start to act, the materials with the volume of the annular material spoon can be taken out each time along with the pushing and retracting of the air cylinder until the set required fine value is reached, the action is stopped, and the fine adjustment is finished once;

in more detail:

referring to fig. 1 to 4, the cylinder can control each annular material spoon to reciprocate between the plate body and the bin body, and the material part in the bin body is separated in the movement process, so that the purpose of accurate blanking is achieved;

for example: the device is arranged in a blanking pipe, a metering storage bin is always in a full state during blanking, materials can be provided for subsequent precise adjustment, for example, 15kg of materials with required dosage are arranged in the blanking pipe, the materials automatically fill the storage bin with the materials during blanking, when 14.5kg of materials are reached, a valve in the blanking pipe is closed, a cylinder is started, the materials drive an annular material spoon to fall once along with the action of the cylinder, (assuming that the materials filled in the annular material spoon is 0.1kg, the cylinder only needs to act for 5 times to complete the precise adjustment), after 15kg of materials is reached, the charging is stopped, the dosage is completed, the blanking valve is opened to continue blanking, the metering storage bin is filled with the materials, and the precise adjustment of the next dosage can be carried out;

it should be noted that:

the purpose of setting the shape of the ring-shaped material spoon into a circular truncated cone shape is as follows: when annular material spoon reciprocating motion between bottom plate and measurement storage silo, it promotes the material to be convenient for, promptly: compared with the annular material spoon with the vertically arranged inner wall, the obliquely arranged inner wall is more convenient when materials are pushed;

moreover, the sealing plate that sets up between adjacent annular material spoon can avoid the material in the measurement storage silo to reveal when switching annular material spoon, and then guarantees accurate regulation.

Example 2, the difference from example 1 is that:

as shown in fig. 5, in the embodiment of the present invention, the material pushing module 5 includes a fixed block 5a fixedly connected to the inner side wall of the discharging tube 1, a rotating shaft 5b rotatably connected to the bottom of the fixed block 5a, and a main gear 5c rotatably connected to the bottom of the rotating shaft 5b, wherein a discharging opening 5d is disposed on the main gear 5c and is circumferentially spaced around the rotating shaft 5b, a transmission opening 5e corresponding to the main gear 5c is disposed on the outer side wall of the discharging tube 1, and a secondary gear 5g driven by a motor 5f and engaged with the main gear 5c is movably disposed in the transmission opening 5 e.

In the embodiment of the present invention, there may be 1 shock absorbing column 22.

In the embodiment of the present invention, there may be 4 feed openings 5 d.

By adopting the technical scheme: different from embodiment 1, this embodiment adopts the mode of rotating the accurate accuse material to realize accurate regulation, and its principle is: the motor drive pinion rotates to drive the master gear and rotate, when the master gear rotates, the feed opening interval passes through between the storehouse body and the plate body, and with the interior material area in the storehouse, and then accomplish the unloading, its advantage is, carries out the rotatory circulation through a plurality of feed openings and alternates, compares two reciprocal alternate modes of annular material spoon, and the efficiency of its regulation is higher.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
