Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel aggregate conveying equipment, in particular to a sand and gravel aggregate bin feeding device. Background Technique

[0002] As the main raw material in concrete, aggregate plays a role of skeleton and support in buildings. When mixing materials, when cement is stirred with water, it becomes a thin paste. If no aggregate is added, it will not be able to form and will not be usable. Therefore, aggregate is a very important raw material in construction. In aggregate production, the crushed aggregate needs to be stored in the bin according to the particle size respectively. During this period, some material lifting equipment such as screw conveyors or elevators are needed, and elevators are most used in on-site production because they can adapt to the lifting of various particle size materials.

[0003] In the prior art, the Chinese utility model patent with the publication number of CN220744287U and the name of a hot aggregate elevator has its buckets arranged vertically up and down on the belt. When the buckets discharge materials, part of the materials cannot fall into the discharge port, resulting in material backflow and low conveying efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sand and gravel aggregate bin feeding device to solve the problem that the buckets of a general material elevator are arranged vertically up and down on the belt, and when the buckets discharge materials, part of the materials cannot fall into the discharge port, resulting in material backflow and low conveying efficiency.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A sand and gravel aggregate bin feeding device includes a silo. The feeding end of the silo is communicated with the discharging end of the feeding device. The feeding device includes a housing, a motor, a roller, a conveyor belt and buckets. A plurality of the rollers are rotatably installed on the housing in an inverted triangle or inverted trapezoid shape. The conveyor belt is tensioned on a plurality of the rollers. The power output end of the motor is connected to the outer end of one of the rollers. A plurality of the buckets are evenly installed on the conveyor belt. An outlet is arranged on the housing, and at least one of the buckets on the inclined part of the conveyor belt is located directly above the outlet.

[0007] A further technical solution is that: the two sides of the conveyor belt are provided with edges, and the outer edges of the edges protrude from the buckets.

[0008] A further technical solution is that: a connecting pipe is arranged between the outlet and the top of the silo. The connecting pipe is arranged to incline downward and its lower end is communicated with the top of the silo.

[0009] A further technical solution is that at least one of the rollers not connected to the power output end of the motor is slidably connected to the housing.

[0010] A further technical solution is that the plurality of rollers are in the shape of a right-angled inverted trapezoid, and the inclined side is close to the discharge port.

[0011] A further technical solution is that a silo is provided at the bottom of the housing.

[0012] Compared with the prior art, at least one of the beneficial effects that the present utility model can achieve is as follows:

[0013] The present utility model provides a feeding device for sand and gravel aggregate into a silo. Based on a material hoist, the structure is changed. A plurality of rollers are arranged in an inverted triangle or inverted trapezoid layout and rotatably installed in a housing, so that the buckets on the conveyor belt form a vertical and horizontal material dropping difference, ensuring that more materials can fall onto the discharge port of the housing and improving the material conveying efficiency.
