Изобретение относитс к пищевой про «з1шленности и может быть использовано во всех отрасл х народного хоз йства, где возникает необходимость распределени потока сыпучего материала по бункерам.The invention relates to food processing and can be used in all sectors of the national economy, where it is necessary to distribute the flow of bulk material into bunkers.

Известен способ управлени процессом загрузки бункеров сыпучим материалом , предпочтительно хлопковыми семенами, предусматривающий измерение верхнего и нижнего уровней в последнем по ходу загрузки бункера путем изменени сечени всех выходных точек транспортного элемента по определенному закону l.A known method for controlling the process of loading bunkers with bulk material, preferably cotton seeds, involves measuring the upper and lower levels in the latter as the bunker is loaded by changing the cross section of all output points of the transport element according to a certain law l.

Недостатками известного способа вл ютс его сложность и потери сыпучего материала, высыпающегос из дальнего конца шнека.The disadvantages of this method are its complexity and the loss of bulk material poured from the far end of the auger.

Цель изобретени - уменьйение потерь сыпучего материала и более надежное обеспечение загрузки бункеров .The purpose of the invention is to reduce the loss of bulk material and more reliable ensuring the loading of bins.

Поставленна цель достигаетс тем, что в способе управлени процессом загрузки бункеров сыпучим материалом, предпочтительно хлопко выми семенами, предусматривающем измерение верхнего и нижнего уровней в последнем по ходу загрузки бун: кера, отличительной особенностью вл етс то, что управление загрузкой бункеров осуществл ют одновре10 менной подачей материала во все бункера в зависимости от верхнего и нижнего уровн в последнем бункере .The goal is achieved by the method of controlling the process of loading bunkers with bulk material, preferably cotton seeds, which involves measuring the upper and lower levels in the latter along the loading of the bun: kera, a distinctive feature is that the loading of the bunkers is carried out simultaneously. material in all bins depending on the top and bottom level in the last bin.

Claims

The device comprises a screw 20 transport element 1, an imbernup valve 2, 3-t-3-n storage hoppers, an upper level sensor C, a sensor, 5 lower level, an actuator 6 and a key 7 and 8. The method is carried out as follows. Bulk material enters the screw transport element and is distributed exponentially in transport element 1. At the same time, the flow of bulk material occurs through the exit windows located in the body of the transport element. Under the windows set p bunkers 3, which receives bulk material. As a result of the exponential law of the distribution of flows of bulk material, the first storage bin is first filled, then the second: etc., and the fifth hopper is filled with the latter. Consequently, based on the law of the exponential distribution of bulk material along the auger length, bulk material accumulates along the auger length or otherwise all storage hoppers, excluding the latter, are filled if the bulk material enters in sufficient quantities. Therefore, according to the state of filling of the last storage bunker, the whole system is filled, and therefore the state is regulated. In the last storage bin, sensors i and 5 of the upper and lower levels are installed. When the last storage bin is empty, the output of sensor 5 appears 1. The output of sensor 5 via key 7 enters the input of the actuator 6, the output of which is connected to the gate valve 2 and opens the input of the transport element. When in the last bunker the sensor 5 of the lower level is activated, at the output of which O appears, the position of the slide gate valve does not change. If the last storage bin is filled to the top, O comes to the output of the lower level sensor 5, and the output of the upper level sensor is 1. The output of the upper level sensor through the key 8 and the actuator 6 acts on the gate valve 2, which secures the transport input element, as a result of which the supply of seeds to storage hoppers is reduced. The stroke of the gate valve is determined by the type of actuator, in which the rotational movement of a single-turn engine is converted into a forward movement of the gate, and the rotation of the actuator motor is reversed by connecting the motor winding to the housing. As a result, the implementation of the proposed method for controlling the process of loading bunkers with bulk material reduces the loss of bulk material due to the fact that the control process is simplified, namely, control is reduced to one parameter. Claims The method of controlling the process of loading bunkers with bulk material, preferably cotton seeds, involves measuring the upper and lower levels in the latter along the loading bin, characterized in that, in order to reduce the loss of bulk material and more reliably ensure the loading of bins, the process of loading the bins is controlled Simultaneous feeding of material into all bins depending on the upper and lower levels in the latter.
