Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a chain plate feeding mechanism. Background Technology

[0002] The feeding mechanism is an important piece of equipment in industrial production. It is mainly used to move raw materials, materials or products from one place to another to meet the needs of the production line. Scrap steel is often generated in industrial production. This includes steel scrap that does not become a product during the steel plant production process, as well as steel materials from scrapped equipment and components. Steel is a recyclable raw material. When large-scale recycling is carried out, a feeding mechanism is needed to put the scrap steel into a crusher for crushing.

[0003] For example, Chinese utility model patent application number CN216071861 U discloses a large-angle conveying device for scrap steel crushing, specifically relating to the field of conveying equipment. Several conveying plates have four slots arranged in an array on one side near the rotating rod. By pulling the insert rod out of the slot and then moving the fixing rod, the fixing rod drives the adjusting plate to move in the first groove. This avoids the situation where the height of the conveying plate cannot be adjusted, thereby achieving the purpose of facilitating the adjustment of the adjusting plate.

[0004] However, the above-mentioned transportation device still has the following problems when in use. By setting several transport plates on the first conveyor belt, the scrap steel can be carried upward by the transport plates when the first conveyor belt moves upward. However, the scrap steel plate itself is heavy, and it is difficult to transport it by the conveyor belt. In addition, the scrap steel is also prone to retaining sharp corners, which can easily tear the conveyor belt when transported by the conveyor belt. Therefore, this application proposes a chain plate feeding mechanism to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a chain plate feeding mechanism to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a chain plate feeding mechanism, which includes a protective shell. A feeding hopper is installed on the bottom side of the protective shell, and a discharge port is installed below the top of the protective shell. A lifting and feeding assembly is also provided inside the protective shell. The lifting and feeding assembly includes two chain belts installed inside the protective shell. Drive sprockets are installed at both ends and the middle bend of the chain belts. Multiple lifting plates are provided between the two chain belts.

[0007] The bottom of the lifting plate is provided with a hopper for loading scrap steel, and bushings are fixedly installed on both ends of the lifting plate. The bushings are rotatably connected to the chain belt, and a reset torsion spring is connected between the bushings and the chain belt to reset the bushings after rotation. A sensing gear is fixedly installed on the outside of the bushings, and two sensing tooth blocks are provided near the discharge port. The sensing gears and sensing tooth blocks cooperate with each other.

[0008] When the chain belt drives the lifting plate close to the discharge port, the induction gear meshes with the induction tooth block and rotates. The rotation of the induction gear drives the lifting plate to rotate through the bushing, so that the scrap steel in the lifting plate is poured out through the discharge port.

[0009] Preferably, a first pulley is fitted on the outer end of the central shaft of the lowest drive sprocket, and a second pulley is connected to the first pulley via belt drive. Two drive motors are also installed on the outside of the protective housing, and the output shafts of the drive motors extend into the protective housing and are connected to the central shaft of the corresponding second pulley.

[0010] Preferably, the protective housing is further provided with an adjustment component, which includes a pressure arc plate. The pressure arc plate is located above the bend of the chain belt, and the top of the pressure arc plate is movably mounted inside the protective housing via a hinge shaft. A control push rod is also installed inside the protective housing, and the output shaft of the control push rod is hinged to the free end of the pressure arc plate.

[0011] Preferably, the bottom end of the feeding hopper extends to the protective shell and is connected to a discharge port. The opening of the discharge port is inclined, and three distribution plates are installed on the inner wall of the discharge port. The straight line formed by the distribution plates is parallel to the inclined surface of the discharge port.

[0012] Preferably, an observation window is installed near the top of the protective shell close to the feeding hopper, and a support frame is installed at the bottom of the inclined surface of the protective shell, the support frame being a triangular structure.

[0013] Compared with existing technologies, this invention has the following advantages: Two chain belts are installed inside the protective shell, and multiple lifting plates are arranged between the two chain belts. The bottom of each lifting plate is connected to a hopper for loading material. When scrap steel enters the protective shell, the chain belts drive the lifting plates upwards, and the hoppers lift the scrap steel for convenient upward transport. Furthermore, the design of the protective shell and chain belts makes them less susceptible to damage from scrap steel, greatly extending their service life. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0023] Depend on Figure 1-2 This utility model discloses a chain plate feeding mechanism, including a protective shell 1. A feeding hopper 11 is installed on the bottom side of the protective shell 1, and a discharge port 12 is installed below the top of the protective shell 1. A lifting and feeding assembly 2 is also provided in the protective shell 1. The lifting and feeding assembly 2 includes two chain belts 21 installed inside the protective shell 1. Drive sprockets 23 are driven to the two ends and the middle bend of the chain belts 21. Multiple lifting plates 22 are arranged between the two chain belts 21. In use, scrap steel can be fed into the protective shell 1 through the feeding hopper 11. The chain belts 21 are driven to roll by the drive sprockets 23. With the cooperation of the lifting and feeding assembly 2, the scrap steel is lifted and discharged outward from the discharge port 12. The above structure is a conventional setting of chain mechanism, so it will not be described in detail in this embodiment.

[0024] The key improvement in this embodiment is as follows:

[0025] Depend on Figure 3-6 The bottom of the lifting plate 22 is provided with a hopper plate 221 for loading scrap steel, and bushings 222 are fixedly installed on both ends of the lifting plate 22. The bushings 222 are rotatably connected to the chain belt 21, and a reset torsion spring 225 is connected between the bushings 222 and the chain belt 21 to reset the bushings 222 after rotation. A sensing gear 224 is fitted on the outside of the bushings 222, and two sensing tooth blocks 121 are provided near the discharge port 12. The sensing gear 224 cooperates with the sensing tooth blocks 121.

[0026] When the chain belt 21 drives the lifting plate 22 to approach the discharge port 12, the sensing gear 224 meshes with the sensing tooth block 121 and rotates. The rotation of the sensing gear 224 drives the lifting plate 22 to rotate through the bushing 222, so that the scrap steel in the lifting plate 22 is poured out through the discharge port 12. When it leaves the sensing tooth block 121, the lifting plate 22 rotates and resets under the action of the reset torsion spring 225.

[0027] Specifically, during operation, the drive sprocket 23 drives the chain belt 21 to continuously transmit power. The chain belt 21 then pushes multiple lifting plates 22 upwards. To effectively load and transport scrap steel upwards, a scoop plate 221 is installed at the bottom of the lifting plates 22. When the chain belt 21 pushes the lifting plates 22, the scoop plate 221 can scoop up the scrap steel and lift it. To discharge the scrap steel from the scoop plate 221 through the discharge port 12, the induction gear 224 on the bushing 222 engages with the discharge port 12. The sensing tooth block 121 at the feed port 12 cooperates to push the bushing 222 and the lifting plate 22 to flip, so that the scrap steel can be poured out. In addition, a support shaft 223 is rotatably mounted inside the bushing 222. The support shaft 223 is fixedly installed on the chain belt 21. One end of the reset torsion spring 225 is connected to the inner wall of the bushing 222, and the other end of the reset torsion spring 225 is connected to the support shaft 223. When the sensing gear 224 disengages from the sensing tooth block 121, the reset torsion spring 225 will reset, thereby pushing the lifting plate 22 to reset, and the operation is repeated.

[0028] In this embodiment, a first pulley 24 is also fitted on the outer end of the central shaft of the drive sprocket 23 located at the bottom. A second pulley 25 is connected to the first pulley 24 via a belt 26. Two drive motors 27 are also installed on the outside of the protective housing 1. The output shaft of the drive motor 27 extends into the protective housing 1 and is connected to the central shaft of the corresponding second pulley 25. The drive motor 27 can drive the second pulley 25 to rotate. Due to the cooperation of the belt 26, the first pulley 24 and the second pulley 25, the drive sprocket 23 can be driven to rotate, thereby driving the chain belt 21 to move.

[0029] In this embodiment, an adjustment component is also provided inside the protective housing 1. The adjustment component includes a downward pressing arc plate 28, which is disposed above the bend of the chain belt 21. The top of the downward pressing arc plate 28 is movably mounted inside the protective housing 1 via a hinge shaft 281. A control push rod 282 is also installed inside the protective housing 1. The output shaft of the control push rod 282 is hinged to the free end of the downward pressing arc plate 28.

[0030] Furthermore, in order to adjust the tension of the chain belt 21 and keep the chain belt 21 running smoothly while always in transmission contact with the drive sprocket 23, the control push rod 282 can be activated to change the position of the pressure plate 28. The pressure plate 28 can squeeze the chain belt 21 downward to adjust the tension of the chain belt 21.

[0031] In this embodiment, the bottom end of the feeding hopper 11 extends to the protective shell 1 and is connected to a throwing port 111. The opening of the throwing port 111 is inclined. Three material distribution plates 112 are also installed on the inner wall of the throwing port 111. The straight line formed by the material distribution plates 112 is parallel to the inclined surface of the throwing port 111. Furthermore, the bottom end of the feeding hopper 11 is also connected to the throwing port 111. The opening of the throwing port 111 is inclined, so that when the scrap steel is fed into the throwing port 111, it can be evenly scattered inside the protective shell 1. The material distribution plates 112 installed inside the throwing port 111 can ensure that the scrap steel is evenly filled into the throwing port 111.

[0032] This utility model discloses a chain plate feeding mechanism that lifts and raises the feeding components to raise scrap steel, effectively solving the problem of easy damage to the conveyor belt caused by the use of conveyor belts to transport scrap steel in the prior art.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
