Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a feeding device for concrete processing. Background Art

[0002] Concrete processing is made by mixing cement, stone, sand and other raw materials according to proportions. The mixing process is completed using a mixer. During the processing, the raw materials are transported to the feeding device through a conveyor belt, so that the raw materials enter the mixer under the guidance of the feeding device. In the engineering direction, the feeding device is usually fixed at a high place, and the materials are added above the mixer.

[0003] However, when adding materials, the cement is too fine and easily adheres to the metal feeding device. After multiple additions, it will form a thick bond on the feeding device, causing the tilting sliding force to weaken, affecting the sliding feeding of the feeding device, and the mixer will stop feeding after the required raw materials are sufficient, but some of the raw materials in the feeding device will continue to fall, and some raw materials will still be added when it is necessary to stop. The raw materials cannot be blocked in time, affecting the mixing ratio. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the preferred implementation scheme of the present invention is further described below in conjunction with specific implementation schemes and accompanying drawings. Example

[0020] See also Figure 1-Figure 5 The utility model provides a feeding device for concrete processing, which includes an opening and closing structure 1, a guide pipe 2, a feeding pipe 3, and a motor 4. The motor 4 is embedded on the outside of the opening and closing structure 1, the opening and closing structure 1 is installed at the lower end of the guide pipe 2, the guide pipe 2 is welded to the lower end of the feeding pipe 3, the guide pipe 2 is a columnar structure that is wide at the top and narrow at the bottom, and four rods at the same level are arranged on the outside of the feeding pipe 3, which has a carrying and supporting effect. The motor 4 is connected to the electric wire, so that the raw material enters from the feeding pipe 3 and enters the opening and closing structure 1 in the guide pipe 2, and then the opening and closing of the opening and closing structure 1 is controlled by the motor 4, so that the opening and closing structure 1 can control the addition of raw materials in a timely and rapid manner.

[0021] The guide tube 2 is provided with a conversion plate 21, a cleaning rod 22, and an inclined plate 23. The cleaning rod 22 is frictionally matched with the inner side of the inclined plate 23. The cleaning rod 22 is installed at the upper end of the conversion plate 21. The conversion plate 21 is frictionally matched with the inner side of the inclined plate 23. The inclined plate 23 is welded to the lower end of the feeding tube 3. The opening and closing structure 1 is installed at the lower end of the inclined plate 23. The cleaning rod 22 has an inclination angle of 20 degrees and has a guiding effect. When the raw material passes through the inclined plate 23, it is accelerated by gravity on the conversion plate 21, so that a part of the gravity is converted into the rotational force of the conversion plate 21, driving the cleaning rod 22 to clean the inner side of the inclined plate 23 to prevent the raw material from adhering to the inner wall of the inclined plate 23.

[0022] The conversion plate 21 is provided with a circular ring e1, a force-bearing plate e2, and an arc plate e3. The force-bearing plate e2 is embedded in the inner side of the circular ring e1, and the arc plate e3 is welded to the outer side of the circular ring e1. The arc plate e3 is frictionally matched with the inner side of the inclined plate 23. The cleaning rod 22 is installed at the upper end of the circular ring e1. The force-bearing plates e2 are provided with six inclined plates. The arc plate e3 is made of arc-shaped aluminum alloy and has the characteristics of strong toughness and large sliding force. Therefore, the force-bearing plate e2 is impacted by the raw material to form a rotational force, so that the circular ring e1 rotates in the inclined plate 23 through the outer arc plate e3, driving the cleaning rod 22 at the upper end of the circular ring e1 to clean.

[0023] The cleaning rod 22 is provided with a sliding plate a, an extrusion strip s, and a connecting rod w. The connecting rod w runs through the extrusion strip s, and the extrusion strip s is fitted on the side of the sliding plate a. The connecting rod w is installed on the upper end of the conversion plate 21. The sliding plate a is frictionally matched with the inner side of the inclined plate 23. The extrusion strip s is made of rubber material, which has the characteristics of high elasticity and easy deformation and extrusion. Therefore, after the connecting rod w rotates, it drives the sliding plate a to clean the inner wall of the inclined plate 23. At the same time, the sliding plate a is buffered under the elastic force of the extrusion strip s, so that the sliding plate a can be tightly fitted on the inner side of the inclined plate 23 for friction cleaning.

[0024] The opening and closing structure 1 is provided with an opening and closing plate t1, a rotating rod t2, a fixed plate t3, a blocking ring t4, and a compression ring t5. The rotating rod t2 is embedded in the inner side of the fixed plate t3, and the rotating rod t2 runs through the middle of the opening and closing plate t1. The blocking ring t4 is frictionally matched with the inner side of the fixed plate t3. The compression ring t5 is attached to the outer side of the opening and closing plate t1, and the blocking ring t4 is embedded in the outer side of the compression ring t5. The rotating rod t2 is threadedly connected to the motor 4. The fixed plate t3 is installed at the lower end of the guide tube 2. The compression ring t5 is The rubber material has the characteristic of extrusion deformation, so the motor 4 drives the rotating rod t2 to rotate 90 degrees, so that the blocking ring t4 is separated from the inner side of the fixed plate t3, and then the raw material passes through the left and right sides of the rotating rod t2. When closing, the rotating rod t2 rotates 90 degrees in the opposite direction, so that the opening and closing plate t1 drives the blocking ring t4 to contact with the inner side of the fixed plate t3. At the same time, under the deformation extrusion of the compression ring t5, the blocking ring t4 is driven to contact and extrude with the fixed plate t3, so that the blocking ring t4 and the inner side of the fixed plate t3 are completely closed to prevent the raw material from leaking from the gap when closing.

[0025] Working principle: In the utility model, the raw materials enter from the feeding pipe 3 and enter the opening and closing structure 1 in the guide pipe 2. When the raw materials pass through the inclined plate 23, the raw materials perform gravity acceleration impact on the conversion plate 21, so that the force-bearing plate e2 is impacted by the raw materials to form a rotational force, and then the ring e1 rotates in the inclined plate 23 through the outer arc plate e3, so that a part of the gravity impact is converted into the rotational force of the conversion plate 21, driving the cleaning rod 22 to clean the inside of the inclined plate 23. During cleaning, the connecting rod w rotates and drives the sliding plate a to clean the inner wall of the inclined plate 23. At the same time, the sliding plate a is buffered under the elastic force of the extrusion strip s, so that the sliding plate a can fit closely on the inner side of the inclined plate 23 for friction cleaning, avoiding the raw materials from sticking to the inner wall of the inclined plate 23, and preventing the subsequent raw material guidance from being affected.

[0026] In the utility model, the circuit controls the internal operation of the motor 4, so that the motor 4 drives the rotating rod t2 to rotate 90 degrees, so that the blocking ring t4 is separated from the inner side of the fixed plate t3, and then the raw materials pass through the left and right sides of the rotating rod t2. When closing, the rotating rod t2 rotates 90 degrees in the opposite direction, so that the opening and closing plate t1 drives the blocking ring t4 to contact the inner side of the fixed plate t3. At the same time, under the deformation and extrusion of the compression ring t5, the blocking ring t4 is driven to contact and extrude with the fixed plate t3, so that the blocking ring t4 and the inner side of the fixed plate t3 are completely closed to prevent the raw materials from leaking out of the gap when closing. Then, the opening and closing of the opening and closing structure 1 is controlled by the motor 4, so that the opening and closing structure 1 can promptly and quickly control the addition of raw materials, prevent the raw materials in the guide pipe 2 from continuing to be added when the conveying stops, and improve the accuracy of the concrete mixing ratio.
