Automatic proportioning type cement hopper

Abstract

The invention relates to the field of buildings and in particular discloses an automatic proportioning type cement hopper. The automatic proportioning type cement hopper comprises a rack, a stirring mechanism, a feeding hopper and a proportioning mechanism, wherein the feeding holler comprises a feeding part and a discharging pipe; a sealing plate is hinged to the upper part of the discharging pipe; a pull rope is fixed on the sealing plate; the stirring mechanism comprises a motor, a stirring shaft and stirring blades; one end of the stirring shaft and the stirring blades are arranged in thefeeding part; the proportioning mechanism comprises an extension spring, a separating plate, a hydraulic jacking device, an electromagnet, a proportioning box and a baffle plate; the pull rope is fixedly arranged on the baffle plate; the proportioning box is divided into a proportioning cabin and a feeding cabin by the separating plate; two ends of the extension spring are fixedly arranged on thebaffle plate and the separating plate respectively; the bottom of the proportioning box is an inclined surface; the electromagnet can adsorb the baffle plate; a switch is arranged on an inner wall ofthe proportioning box; the separating plate can press the switch; an airbag is fixedly arranged at the bottom of the proportioning cabin; an air inlet is formed in the airbag; a feeding opening is formed in a lateral wall of the feeding cabin. By adopting the automatic proportioning type cement hopper provided by the invention, the quantity of entered raw materials can be controlled.

Description

technical field [0001] The invention relates to the construction field, in particular to a cement hopper. Background technique [0002] In the field of construction, cement hoppers are widely used, and cement hoppers are mainly used in the production process of cement. At present, there is a hopper that can be weighed. A weighing sensor and a weighing controller connected to it are installed on the hopper. The material in the hopper enters the next link after continuous weighing. After the weight reaches the requirement, the weighing sensor Send a signal to the weighing controller, and the weighing controller controls the feeding mechanism to stop feeding, which takes a certain amount of time to respond, so it often causes the actual feeding to exceed the preset value, so errors are prone to occur. [0003] Secondly, during the mixing process of cement production, because the semi-finished cement is very viscous, when the hopper is mixed and falls, it is easy to arch or blo...

At present, there is a hopper that can be weighed. A weighing sensor and a weighing controller connected to it are installed on the hopper. The material in the hopper enters the next link after continuous weighing. After the weight reaches the requirement, the weighing sensor Send a signal to the weighing controller, and the weighing controller controls the feeding mechanism to stop feeding, which takes a certain amount of time to respond, so it often causes the actual feeding to exceed the preset value, so errors are prone to occur

[0003] Secondly, in the mixing process of cement production, because the semi-finished cement is very viscous, when the hopper is mixed and falls, it is easy to arch or block the hopper, so that the subsequent cement cannot fall along the hopper
