Description

Technical Field

[0001] The utility model relates to a conveyor, in particular to a conveyor for processing building gypsum powder. Background Art

[0002] In the process of building gypsum powder processing, raw materials need to be transported, and traditional conveying structures are prone to blockage. In order to solve this problem, a Chinese patent with application number CN202221424437.4 provides a patent for a raw material conveying device for building gypsum powder processing. The structure sets a weighing screen plate so that the raw materials put into the feed opening bin will be screened when passing through the weighing screen plate, and large pieces of raw materials will remain on the upper surface of the weighing screen plate. When the large pieces of raw materials accumulated on the upper surface of the weighing screen plate increase, the pressure on the pressure sensor will increase. When the preset pressure value is reached, the system will control the hydraulic flip push rod to extend, and the hydraulic flip push rod will push the folding rotating column to rotate through the flip push plate, and the large pieces of raw materials on the surface of the weighing screen plate will be dumped onto the surface of the movable baffle plate to achieve unified recovery. Although the above structure can solve the blockage problem through the weighing screen plate to a certain extent, on the one hand, large pieces of raw materials After the material falls on the weighing screen plate, the large pieces of raw materials cannot be broken up. As the number of large pieces of raw materials on the weighing screen plate increases, it is necessary to continuously clean the large pieces of raw materials on the weighing screen plate. During the cleaning, the weighing screen plate cannot play a screening role, so the machine can only stop and wait for the weighing screen plate to reset before continuing to work, affecting efficiency; on the other hand, if the number of large pieces of raw materials is small and they are just flat on the weighing screen plate, the weighing screen plate will be blocked by the large pieces of raw materials and cannot reach the preset value of the pressure sensor, causing subsequent raw materials to accumulate in the feed opening bin, which not only affects the conveying efficiency, but even if the preset value of the pressure sensor is reached later, a large amount of raw materials to be conveyed will be cleaned together with the large pieces of raw materials; on the other hand, although the setting of the weighing screen plate plays a screening role, since the weighing screen plate is stationary, it will also slow down the efficiency of raw material transportation to a certain extent.
