Description

Изобретение относитс к устройст-вам непрерывной подачи сыпучих материалов и может быть использовано дл погрузо-разгрузочных работ в т желой/ легкой промышленност х ив сельском хоз йстве.The invention relates to devices for the continuous supply of bulk materials and can be used for loading and unloading operations in heavy / light industry in agriculture.

.Известно устройство, содержащее загрузочный бункер с выходным отверстием и расположенный под выходным отверстием бункера кожух с заключенным в нем шнеком с приводом A device is known that contains a hopper with an outlet and a casing with an auger with a drive located under the outlet of the hopper.

Недостатком устройства вл етс то, что изменение подачи материала может осуществл тьс только изменением числа оборотов шнека, что св зано с усложнением конструкции привода .The drawback of the device is that the change in the material feed can be carried out only by changing the speed of the auger, which is associated with the complexity of the drive design.

Известно также устройство, содержащее загрузочный бункер с ворошителем и выходным отверстием, подвижную заслонку дл 5того отверсти и расположенный под выходным отверстием бункера рабочий участок в виде заключенного в кожух шнека с приводом его вращени 2.It is also known a device comprising a hopper with a agitator and an outlet, a movable gate for the 5th hole and a working section located under the outlet of the bunker in the form of an auger enclosed in a casing with its rotational drive 2.

Недостатком этого устройства вл етс то, что дл изменени величины подачи материала надо измен ть скорость вращени шнека.A disadvantage of this device is that in order to change the amount of material feed, it is necessary to change the speed of rotation of the auger.

Наиболее близким к предлагаемому вл етс устройство, содержащее загрузочный бункер с выходным отверстием , расположенный под выходным отверстием бункера рабочий участок в виде заключенного в кожух шнека, при этом рабочий участок выполнен с пер.еменньв4 сечением свободного объема между шнеком и кожухом вдоль Closest to the present invention is a device comprising a feed hopper with an outlet, an operating section located under the outlet of the bunker in the form of an auger encased in the casing, while the working section is made with cross-section of free volume between the screw and the casing along

10 направлени подачи материала 3.10 material feed direction 3.

Однако известное устройство не обеспечивает плавного изменени подачи материала при неизменном положении относительно друг друга шне15 ка и загрузочного бункера.However, the known device does not provide a smooth change in the material feed at a constant position relative to each other of the screw and the hopper.

Цель изобретени - улучшение плавного дозировани материала.The purpose of the invention is to improve the smooth dosing of the material.

Поставленна цель достигаетс тем, что в устройство введена уста20 новленна 1«1ежду бункером и рабочим участком подвижна заслонка с фигурной прорезью.The goal is achieved by the fact that the device is inserted into the device 1 "1 between the bunker and the working area of the movable gate with the figured slot.

Claims

30 by the ria hole of FIG. 6 - proposed feeder with a cylindrical barrier; in fig. 7 is a view of B in FIG. 6; in fig. 8 - cylindrical valve with a screw hole. Feeder {FIG. 1) consists of a hopper 1 with agitator 2 and an outlet 3 (Fig. 2), a movable damper 4, made in the form of a disk, the axis of rotation 5 of which is installed outside the hopper 1 on the casing 6, which in the location of the hole 3 has a cone-shaped form. The axis of rotation 5 is provided with a manual drive handle V. The valve 4 is located above the bottom of the hopper 1 and is equipped with a spiral hole 8. Inside the casing is a screw 9, driven by the drive 1.0. The screw screw screw cavity 9 has a conical shape in the working area under the outlet 3 of the hopper 1 and is installed with a gap relative to the cone-shaped part of the casing 6. The feeder (Fig. 3) consists of a hopper 12 with the agitator 13 and an outlet 14 (Fig. 4) The hopper 12 is mounted on the housing 15 / having a cone-shaped shape at the hole location. Inside the housing 15 there is a screw 16, the screw of which the blade 17 has a conical shape and is installed with a clearance oTHocHTejibHO of the tapered part of the casing 15. The screw 16 is connected to the drive 18. Between the cone-shaped parts of the casing 15 and the blade 17 there is a movable conical flap 19 fitted with a screw from- impose 20 {FIG. 5) and the flange 21, with which it is attached to the end face of the casing 15. The feeder (Fig. 6) contains a feed hopper 22 with agitator 23 and an outlet 24 (Fig. 7). Buoys 22 are mounted on the casing 25. Inside the casing 25, a screw 26 is installed, the shaft of which 27 has a conical shape in the working area at the opening of the opening 24 of the hopper 22. A movable cylindrical part is installed between the casing 25 and the screw 26 in the locations of the cone-shaped part 27 a shutter 28 provided with a screw hole 29 (FIG. 8) and a flange (not shown) for fastening the casing 30 to the end face. The feeder operates as follows. When the flap 4 (fig. 1), the flap 19 (fig. 3J and the flap 28 (fig. 4)) are rotated and the holes 8, 20 and 29 of the flap 4, 19 and 28 relative to the holes 3, 14 and 24 of the hopper 1 , 12 and 22, as a result of which the windows formed by the intersection of the openings of the bunkers and dampers, begin to move along the bottoms of the bins. As a result, the material from the bunker can fall on the conical working sections of the screws 9, 16 and 26 in different places differing from each other by the free section volume of the casing 6, 15 and 25 and the screw 9, 16 and 26. Using this difference in volume and the ability to The device to be fed material to different places of the conical working area of the screw can change the material feed at a constant speed of rotation of the screw. Formula of Invention A feeder containing a feed hopper with an outlet, located under the outlet of the bunker a working section in the form of an auger encased in In this case, a working section with a variable cross-section of the free volume between the screw and the casing along the material feed direction, characterized in that, in order to improve the smooth flow rate Vani material introduced therein mounted between the hopper and the valve operating portion is movable with shaped proreeyo.
