Description

Technical Field

[0001] This utility model relates to the field of batching machine hoppers, specifically a new type of environmentally friendly concrete batching machine for concrete production. Background Technology

[0002] The batching machine consists of multiple silos and a weighing belt conveyor. Different silos contain different concrete raw materials. When producing environmentally friendly concrete, one of the silos contains coal powder. The weighing belt conveyor (also known as an electronic belt scale) has a weighing bridge installed on the conveyor frame. When the material passes by, the metering roller detects the weight of the material on the belt conveyor and acts on the weighing sensor through a lever, generating a voltage signal proportional to the belt load. This achieves the effect of measuring the material during feeding. When the material reaches the preset weight, the controller stops the feeding mechanism.

[0003] When pulverized coal is in the silo, it is easy to clump together due to its own weight. When the pulverized coal sticks together or is squeezed together, it will form an arch above the outlet of the container, which will cause powder bridging and affect the continuous discharge efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the present invention, a novel environmentally friendly concrete batching machine for concrete production includes a silo 1. The bottom end of the silo 1 is integrally formed with a downwardly protruding discharge pipe 2. The inner wall of the silo 1 is equipped with a reciprocating mixing mechanism extending to the outside of the silo 1. The discharge pipe 2 is equipped with a discharge mechanism that extends to one end of the discharge pipe 2. One end of the discharge mechanism is equipped with a transmission mechanism that extends to the outside of the discharge pipe 2. The transmission mechanism is connected to the reciprocating mixing mechanism.

[0020] In this embodiment: when the raw material of environmentally friendly concrete, fly ash, is being fed, the feeding mechanism is activated. The running feeding mechanism drives the reciprocating mixing mechanism through the transmission mechanism. The mixing part of the reciprocating mixing mechanism will rotate back and forth inside the silo 1. The reciprocating mixing mechanism will stir the fly ash in the silo 1 and agitate the clumps of coal powder to avoid blockage. Secondly, it can prevent the fly ash from bridging in the silo 1.

[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The reciprocating mixing mechanism includes an agitator 4 disposed in the inner cavity of the hopper 1. A rotating shaft 5 is welded to the outer side of the top of the agitator 4, extending through to the outside of the hopper 1. The rotating shaft 5 is rotatably connected to the hopper 1. A full gear 6 is fixedly installed at one end of the two rotating shafts 5 located outside the hopper 1. The reciprocating mixing mechanism also includes a rack 12 meshing with a full gear 6 below. An elliptical cylindrical guide rod 14 is slidably connected inside the sliding ears at both ends of the rack 12. Fixed seats 13 connected to the outside of the hopper 1 are fixedly installed at both ends of the elliptical cylindrical guide rod 14. A return spring 15 abuts between the fixed seat 13 and one sliding ear of the rack 12. The return spring 15 is sleeved on the outer periphery of the elliptical cylindrical guide rod 14.

[0022] In this embodiment: when the feeding mechanism rotates, the feeding mechanism drives a full gear 6 to rotate through the transmission mechanism. The full gear 6 rotates through the agitator 4, and the agitator 4 drives another full gear 6 to rotate. The rotation of the full gear 6 drives the rack 12 to slide along the elliptical cylinder guide rod 14. At this time, the return spring 15 is compressed. When the half gear 11 and a full gear 6 rotate from the meshing state to the disengaged state, the return spring 15 resets. The reset return spring 15 pushes the rack 12 to reset. At this time, the reset rack 12 drives the meshing full gear 6 to rotate and reset. At this time, the full gear 6 drives the agitator 4 to reset and rotate inside the hopper 1, completing the reciprocating stirring effect.

[0023] Please refer to this carefully. Figure 3 and Figure 4 The feeding mechanism includes a rotary motor 3 installed outside the feeding tube 2. The output shaft of the rotary motor 3 passes through the inner cavity of the feeding tube 2, and a feeding roller 16 is fixedly installed on the output shaft of the rotary motor 3. The feeding roller 16 is located in the inner cavity of the feeding tube 2. Two arc-shaped plates 17 are fixedly installed on the inner wall of the feeding tube 2. The inner circumference of the arc-shaped plates 17 matches the rotation trajectory of the feeding roller 16. There is a feeding channel between the two arc-shaped plates 17.

[0024] In this embodiment: When feeding, the rotary motor 3 is started, and the rotary motor 3 drives the feeding roller 16 to rotate. The outer periphery of the feeding roller 16 is formed with outwardly protruding partition plates. The rotating feeding roller 16 and the partition plates drive the powder material entering the feeding pipe 2 to rotate. When the powder material rotates to the feeding channel, the powder material falls downward onto the conveyor belt device with weighing capacity.

[0025] Please refer to this carefully. Figure 1 and Figure 3 The transmission mechanism includes a drive pulley 8 connected to one end of the feed roller 16 via a synchronous shaft. The synchronous shaft is rotatably connected to the feed tube 2. The drive pulley 8 is driven by a driven pulley 9 via a transmission belt 10. One end of the driven pulley 9 is coaxially fixedly connected to a half gear 11.

[0026] In this embodiment: when the feeding roller 16 rotates, the feeding roller 16 drives the driving pulley 8 to rotate through the synchronous shaft. The driving pulley 8 drives the driven pulley 9 to rotate through the transmission belt 10. The driven pulley 9 drives the half gear 11 to rotate synchronously. During the rotation of the half gear 11, when it meshes with a full gear 6, the reciprocating stirring mechanism rotates in the hopper 1. When the half gear 11 separates from the full gear 6, the reciprocating stirring mechanism resets and rotates in the hopper 1, achieving the reciprocating stirring effect.

[0027] Please refer to this carefully. Figure 3A mounting plate 7 is fixedly installed at the bottom of the top convex plate of the hopper 1. The mounting plate 7 is rotatably connected to the rotating shaft 5 through a bearing. The half gear 11 is rotatably connected to the mounting plate 7 through a rotating shaft.

[0028] In this embodiment, the mounting plate 7 is designed to provide rotational support for the half gear 11 and the driven pulley 9.
