Problems solved by technology

[0003] The existing pit-type batching system usually includes more than 4 storage bins, which only play the role of unloading. The process is that the materials are unloaded from the storage bins in the pit to the conveyor, and then sent to the special setting outside the pit by the conveyor. The metering device carries out weighing and material flow detection. If a certain material is found to be short of material at this time, the alarm signal of material shortage will be fed back to the controller, and then other storage bins in the pit will be started to open; It affects the continuous operation and production efficiency of the mixing station

Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] The mixing plant proposed in the specific embodiment of the present invention is an asphalt mixing plant, which includes a mixing system, a drying drum 7, a lifting and screening system and an automatic feeding device. The material (such as sand, additives, etc.), the drying drum 7 will dry and heat the material, after the material is dried, heated and dehydrated, it will be screened by the lifting and screening system, and then the material that meets the requirements will be measured and sent to the mixing system. The mixing system fully mixes the material with hot asphalt and mineral powder to form an asphalt mixture.

[0024] In this example, if figure 1 As shown, the automatic feedi...

Abstract

The invention discloses an automatic feeding device. According to the automatic feeding device, a belt feeder is arranged below storage bins; a material flow detecting device is arranged at a discharging hole of the belt feeder or at the outlet of a discharge hopper; during material supply, the discharging hole of one or a plurality of storage bins is opened, a material flows to the belt feeder via the discharge hopper, the belt feeder is used for metering the material and supplying the material to a material collecting conveyer, and finally the material is conveyed to a target position by the material collecting conveyer; during a material supply process, the material flow detecting device is used for detecting the material at the discharging hole of the belt feeder in time; when the material flow detecting device detects continuous flow cutoff, a controller is used for controlling the discharging hole of another storage bin to be opened for discharging the material. Besides, the invention also discloses a mixing station comprising the automatic feeding device.

Description

technical field [0001] The invention relates to the manufacturing technology of a mixing station, in particular to a mixing station and an automatic feeding device thereof. Background technique [0002] With the rapid growth of asphalt pavement and the improvement of construction requirements, asphalt mixture is usually produced by professional mixing plants. The mixing station mainly includes batching system, drying heating system, lifting screening system and mixing system, etc. The batching system transports materials with different particle sizes to the drying drum for heating and drying after being metered by the belt feeder according to the gradation. After drying, it is metered by the lifting and screening system and sent to the mixing system for mixing to obtain asphalt mixture. [0003] The existing pit-type batching system usually includes more than 4 storage bins, which only play the role of unloading. The process is that the materials are unloaded from the stora...
