Изобретение относитс к трубопроводному контейнерному пневмотранспорту, в частности к дозирующим устройствам дл загрузки контейнеров пневмотранспортных установок кусковыми сыпучими грузами.The invention relates to pipeline container pneumatic transport, in particular, to metering devices for loading containers of pneumatic transport installations with bulk bulk cargoes.

Известно устройство дл дозированной подачи кусковых грузов в транспортное средство , содержащее накопительный бункер с разгрузочным патрубком, под выпускным отверстием которого установлена дозирующа камера в виде полого цилиндра, установленного с возможностью поворота вокруг продольной оси и имеющего продольное загрузочное окно, причем вдоль другого в направлении поворота продольного кра загрузочного окна цилиндра изнутри его укреплен ролик 1.A device for metering bulk goods into a vehicle is known, comprising a storage bin with a discharge pipe, under the discharge opening of which a metering chamber is installed in the form of a hollow cylinder mounted rotatably around a longitudinal axis and having a longitudinal loading window, along the other in the direction of rotation of the longitudinal the edge of the loading window of the cylinder from the inside of its reinforced roller 1.

В известном устройстве накопительный бункер снабжен ленточным клапанным затвором , лента которого одним концом закреплена на разгрузочном патрубке бункера, а другим - свободно огибает упом нутый ролик .In the known device, the storage bin is provided with a tape valve gate, the tape of which is fixed at one end to the discharge port of the bunker, and the other roller freely bends around the said roller.

Таким образом при повороте дозирующей камеры лента ложитс на ее наружную поверхность. При этом в момент прохождени кромки цилиндра, несущей ролик, мимоThus, when the metering chamber is rotated, the tape rests on its outer surface. In this case, at the moment of passing the edge of the cylinder carrying the roller, past

второй в направлении поворота кромки разгрузочного патрубка возможно заклинивание кусков материала, что может привести к значительному возрастанию сопротивлени повороту камеры вплоть до поломки устрой . ства.the second one in the direction of the turn of the edge of the discharge nozzle may jam the pieces of material, which can lead to a significant increase in resistance to the rotation of the chamber until the device breaks. properties.

Целью изобретени вл етс повыщение надежности работы устройства.The aim of the invention is to increase the reliability of the device.

Это достигаетс тем, что над дозирующей камерой на двух противолежащих продольных сторонах разгрузочного патрубка над 10 дозирующей камерой закреплены с возможностью перемещени в вертикальной плоскости две пластины со встречным наклоном, которые снабжены катками, взаимодействующими с наружной поверхностью полого цилиндра , причем к разгрузочному патрубку накопительного бункера над второй в направлении поворота камеры наклонной пластиной присоединена емкость, сообщенна с полостью патрубка по всей его высоте.This is achieved by the fact that above the metering chamber on two opposite longitudinal sides of the discharge nozzle above the 10 metering chamber there are mounted with a possibility to move in the vertical plane two plates with opposite inclination, which are provided with rollers interacting with the outer surface of the hollow cylinder, and to the discharge nozzle of the storage bin above the second, in the direction of the camera rotation, an inclined plate is attached to a container communicated with the cavity of the nozzle throughout its height.

Claims

20 In FIG. Figure 1 shows schematically the proposed device during the filling of the dosing chamber; in fig. 2 is a section A-A in FIG. one; in fig. 3 - the device at the end of the filling of the dosing chamber. The device contains a hopper 1 with a discharge pipe

2. A dosing chamber is installed under the outlet of the pipe 2. The camera is made in the form of a hollow cylinder 3, which is installed with the possibility of rotation around the longitudinal axis. In cylinder 3 there is a longitudinal loading window 4. Inside cylinder 3, roller 5 is strengthened along the second loading window 4 in the direction of rotation of the longitudinal edge. When dosing, for example, a piece of gravel 40 mm, the diameter of the roller should be larger or at least approximately equal double the maximum possible size of the piece of cargo. On nozzle 2, on two opposite sides parallel to the longitudinal axis of the chamber, plates 6 and 7 are fixed, each having an opposite inclination in relation to the other. Each plate is mounted to move vertically on rubber pads 8. Plates 6 and 7 are mounted with respect to the outer surface of cylinder 3 with a gap smaller in size than the smallest possible piece of dosing weight. This gap is maintained constant by means of rollers 9 fixed on the plates 6 and 7 and interacting with the rotation of the cylinder 3 with its outer surface. To the discharge pipe 2 above the front in the direction of rotation of the cylinder 3 plate 7 attached capacity 10. The operation of the described device is as follows. In the initial position shown in FIG. 1, the loading window 4 of the cylinder 3 is located at the top, and the dosing chamber is filled. Plates 6 and 7 are supported by rollers 9 on the outer surface of cylinder 3, keeping the gap between plates 6 and 7 and the outer surface of cylinder 3 constant for all the manufacturing inaccuracies that are inevitable for such a massive and cumbersome equipment, in particular, for example, for all possible unevenness x the outer surface of the cylinder 3. Such a constant of the said gap, the size of which is chosen to be less than the size of the minimum possible size of a piece of cargo, makes it possible to prevent material from spilling out. The nozzle 2 of the storage bin 1. Upon filling the dosing chamber of the cylinder 3, the latter rotates, while the edge of the cylinder 3, the carrier roller 5, "cuts a column of material in the discharge nozzle 2," of the compartment, the required dose remaining in the cylinder

3. At the end of the process of “cutting off” at the moment of passing the edges of the cylinder 3 carrying roller 5, to the edge of the unloading nozzle 2 when even the largest (possible) piece gets between these edges, the latter is pushed out by the roller 5 back to the unloading nozzle 2 ( by turning the roller) and freely placed in the container 10. Thus, the proposed device has a simple design, while ensuring a sufficiently high reliability of operation on bulk and bulk cargo. Apparatus of the Invention A device for metering lump cargo into a vehicle, mainly in containers of pneumatic conveying installations, comprising an accumulation hopper with a discharge pipe, under the discharge opening of which there is a metering chamber in the form of a hollow cylinder installed rotatably around a longitudinal axis and having a longitudinal loading window, moreover, along the other, in the direction of rotation of the longitudinal edge of the loading window of the cylinder, a roller, which is different In order to increase the reliability of the device, on two opposite longitudinal sides of the discharge nozzle above the metering chamber, two plates with opposite inclination that are provided with rollers interacting with the outer surface of the hollow cylinder can be moved in the vertical plane to the discharge nozzle storage bin, above the second in the direction of rotation of the camera inclined plate attached capacity, communicated with the cavity of the pipe throughout its height.
