Embodiment Construction

[0039] As mentioned in the background art, it is difficult to accurately control the feeding amount of the current machine-made sand equipment, thereby reducing the production efficiency of the machine-made sand equipment.

[0040] Based on the above research, the embodiment of the present invention provides a feed volume control device for machine-made sand equipment. The material volume in the chamber is detected by the material level detector, and the controller controls the material volume according to the material volume detected by the material level detector. The gate works, for example, when the amount of material in the chamber is too small to meet the demand of the machine-made sand equipment, the controller will automatically control the gate to open, and then make the discharge port of the hopper larger, so as to increase the chamber The amount of material in the chamber can increase the amount of material supplied to the machine-made sand equipment; when the amount...

Abstract

The invention discloses a device for controlling the feeding amount of machine-made sand equipment. The device comprises a hopper, a belt conveyor, a wedge disc, a guide chute and a controller, wherein the wedge disc is used for controlling the opening size of a discharge opening of the hopper, the guide chute is connected with the discharge opening and located on the upper portion of the belt conveyor, the guide chute and the upper portion of the belt conveyor form a cavity for preventing materials from overflowing, a discharge port enabling the materials in the cavity to be discharged underconveying of the belt conveyor is formed in the guide chute, and a material level detecting meter used for detecting the material amount in the cavity is arranged in the cavity; and the controller isused for controlling work of the wedge disc according to the material amount detected by the material level detecting meter. The invention further discloses a method for controlling the feeding amountof the machine-made sand equipment. The method comprises the following steps that the first feeding amount of the machine-made sand equipment is obtained; whether the first feeding amount is smallerthan a preset feeding amount threshold value or not is judged; and if yes, the rotating speed of the belt conveyor used for providing the materials for the machine-made sand equipment is increased.

Description

technical field [0001] The present invention relates to the technical field of building materials machinery equipment, in particular to a device for controlling the feeding amount of machine-made sand equipment, and also relates to a method for controlling the feeding amount of machine-made sand equipment. Background technique [0002] With the increasing demand for machine-made sand, there are higher requirements for the production capacity of machine-made sand equipment. When providing raw materials for machine-made sand equipment, it is necessary to consider the production capacity and sand-making efficiency of machine-made sand equipment. When the input amount exceeds the processing capacity of the machine-made sand equipment, it will cause material blockage of the equipment, which will seriously affect the life of the equipment, and even cause shutdown accidents; if the input amount is too small, the production capacity of the equipment cannot be fully utilized and the p...
