[0023] 1. The technical solution of this application, through the design of the frame box and the electric push rod, enables the hinged electric push rod on the base surface to operate during the use of the feeding equipment for the calcining kiln. Since the electric push rod is hinged between the frame box and the base, the electric push rod can push the frame box, thereby facilitating the adjustment of the tilt angle between the frame box and the base, thus facilitating the automatic feeding of materials into the calcining kiln.

[0024] 2. The technical solution of this application, through the design of the ear seat, straight shaft, pad, buffer spring, frame bucket, and pad, allows the material discharged from the inside of the frame box to fall onto the frame bucket during the use of the feeding equipment for the calcining kiln. This facilitates the material being discharged into the calcining kiln using the frame bucket. The frame bucket is arranged at an angle to the calcining kiln, and the vibration motor at the bottom of the frame bucket operates. The operation of the vibration motor easily drives the frame bucket to vibrate, allowing the material on the surface of the frame bucket to slide stably down the frame bucket into the calcining kiln under the vibration force. This facilitates the calcination of the material in the calcining kiln and reduces the impact on the feeding equipment. At the same time, the buffer spring between the pad and the ear seat supports the frame bucket. The ear seat is hinged to the frame bucket through the straight shaft, which facilitates the adjustment of the angle between the frame bucket and the frame box. This allows the frame bucket to stably convey the material under the vibration force, facilitating its calcination. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0035] Please see Figures 1-7 This utility model provides a technical solution: an automatic feeding device for a calcining kiln, including a base 1 and an ear seat 6. A frame box 2 for support is hinged to the top surface of the base 1 via a rotating shaft, and an electric push rod 3 for adjustment is hinged between the frame box 2 and the base 1 via a rotating shaft. A straight shaft 7 for support is rotatably installed on the inner circumference of the ear seat 6, and a frame bucket 8 adapted to the discharge end of the frame box 2 is hinged to the outer circumference of the straight shaft 7. A vibrating motor 9 for feeding is mounted on the bottom surface of the frame bucket 8, and there are multiple sets of vibrating motors 9. A pad plate 4 corresponding to the ear seat 6 is mounted on one side of the bottom end surface of the frame box 2, and a support pad 10 for support is mounted on one side of the bottom end surface of the frame bucket 8, and there are multiple sets of support pads 10. A buffer spring 5 is mounted on the end of the support pad 10 away from the frame bucket 8 and between the ear seat 6 and the pad plate 4, and there are multiple sets of buffer springs 5.

[0036] When in use, the electric push rod 3 hinged on the surface of the base 1 can operate during the use of the feeding equipment for the calcination kiln. Since the electric push rod 3 is hinged between the frame box 2 and the base 1, the electric push rod 3 can push the frame box 2, thereby facilitating the adjustment of the tilt angle between the frame box 2 and the base 1, which facilitates the automatic feeding of the inside of the calcination kiln.

[0037] During the use of the feeding equipment for the calcining kiln, the material discharged from the inside of the frame box 2 can fall onto the frame hopper 8, making it convenient to discharge the material into the calcining kiln using the frame hopper 8. The frame hopper 8 is arranged at an angle to the calcining kiln, and the vibration motor 9 at the bottom of the frame hopper 8 operates. The operation of the vibration motor 9 can easily drive the frame hopper 8 to vibrate, so that the material on the surface of the frame hopper 8 can stably slide down the frame hopper 8 into the calcining kiln under the vibration force, which facilitates the calcination of the material in the calcining kiln and reduces the impact on the feeding equipment. At the same time, the buffer spring 5 between the pad plate 4 and the ear seat 6 can support the frame hopper 8. Meanwhile, the ear seat 6 is hinged to the frame hopper 8 through the straight shaft 7, which makes it easy to adjust the angle between the frame hopper 8 and the frame box 2, and allows the frame hopper 8 to stably convey the material under the vibration force, which is convenient for calcination.

[0038] like Figure 2 and Figure 6 As shown, the end of the buffer spring 5 away from the pad 10 is hinged to a straight arm 11 via a pivot, and the end of the straight arm 11 away from the buffer spring 5 is hinged to an adjustment angle plate 12, and the end of the angle plate 12 away from the straight arm 11 is hinged to a support lug 13.

[0039] In use, the pad 10 at the bottom of the frame bucket 8 provides convenient support for the buffer spring 5 and prevents the frame bucket 8 from vibrating and affecting the straight arm 11. The straight arm 11 is conveniently hinged to the spring seat between the buffer spring 5 and the straight arm 11. At the same time, the corner plate 12 is hinged to the straight arm 11, and the ear block 13 is hinged to the corner plate 12. This allows the ear block 13 to be installed in a suitable position on the outside of the calcining kiln, and the straight arm 11, corner plate 12, and ear block 13 can support the frame bucket 8, thereby enabling the frame bucket 8 to stably transport materials.

[0040] like Figure 2 and Figure 7 As shown, the discharge end of the frame box 2 is equipped with a guide hopper 14 that is compatible with the frame hopper 8.

[0041] When in use, the guide hopper 14 at the discharge end of the frame box 2 can conveniently limit the material, so that the material can fall stably onto the surface of the frame hopper 8 and reduce the situation of the material scattering randomly.

[0042] like Figure 2 and Figure 7 As shown, the bottom surface of the guide hopper 14 is fitted with a ring seat 15 for support, and there are multiple sets of ring seats 15. A pull rod 16 for adjustment is slidably installed inside the ring seat 15, and a support plate 17 is fitted at one end of the pull rod 16 inside the guide hopper 14. A cleaning brush bristle 18 is glued to the end of the support plate 17 away from the pull rod 16.

[0043] During use, the pull rod 16 in the bottom ring seat 15 of the guide hopper 14 facilitates the support plate 17, and the support plate 17 drives the brush 18 to brush the surface of the conveyor belt 24 after the material is conveyed by the conveyor belt 24, which is convenient for cleaning the residual material.

[0044] like Figure 2 and Figure 7 As shown, a thrust spring 19 located on the outer periphery of the pull rod 16 is assembled between the ring seat 15 and the support plate 17, and there are multiple sets of thrust springs 19.

[0045] In use, the thrust spring 19 facilitates the pushing of the support plate 17, so that the support plate 17 can drive the bristles 18 to make closer contact with the conveyor belt 24, thereby improving the cleaning effect of cleaning the conveyor belt 24.

[0046] like Figure 2 , Figure 5 and Figure 6 As shown, shock absorbers 20 located on the inner circumference of the buffer spring 5 are installed between the pad 4 and the ear seat 6 and at the end of the pad 10 away from the frame 8.

[0047] When in use, the shock absorber 20 can be used in conjunction with the buffer spring 5 to suppress the vibration of the frame bucket 8 when the vibrating motor 9 stops operating, and can assist the frame bucket 8 when it vibrates to prevent the frame bucket 8 from jumping too much or vibrating too much, which would cause the material to splash randomly.

[0048] like Figure 2 and Figure 4 As shown, the frame box 2 is equipped with a support base 22, and a guide roller 23 for transmission is rotatably installed in the support base 22. There are multiple sets of guide rollers 23, and a conveyor belt 24 for feeding is assembled between the multiple sets of guide rollers 23. Rubber strips 25 for auxiliary feeding are assembled on the outer periphery of the conveyor belt 24, and there are multiple sets of rubber strips 25.

[0049] When in use, the guide rollers 23 in the base 22 rotate under the operation of the drive motor, and the conveyor belts 24 between the multiple sets of guide rollers 23 can operate synchronously and transport the material. At the same time, the multiple sets of rubber strips 25 on the surface of the conveyor belt 24 can provide certain limiting performance, so that the conveyor belt 24 can transport the material to be calcined more stably, which is convenient for subsequent calcination.

[0050] like Figure 2 and Figure 5 As shown, a corrugated rubber tube 21 located on the outer periphery of the buffer spring 5 is assembled between the pad 4 and the ear seat 6, and there are multiple sets of corrugated rubber tubes 21.

[0051] When in use, the corrugated rubber tube 21 can protect the buffer spring 5 between the pad 4 and the ear seat 6, so that the buffer spring 5 can operate more stably and can easily support the frame bucket 8.

[0052] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the feeding equipment for the calcining kiln, the hinged electric push rod 3 on the surface of the base 1 can operate. Since the electric push rod 3 is hinged between the frame box 2 and the base 1, it can push the frame box 2, thus facilitating the adjustment of the tilt angle between the frame box 2 and the base 1. This facilitates subsequent automatic feeding into the calcining kiln. Simultaneously, the frame hopper 8 is hinged to the ear seat 6 via the pad 4 and the straight shaft 7, facilitating the adjustment of the tilt angle between the frame hopper 8 and the frame box 2. After adjustment, the ear block 13... Installed at a suitable position at the feed inlet of the calcining kiln, the straight arm 11, angle plate 12, and ear block 13 can be hinged together and supported by the pad 10. This allows the material to be calcined to slide stably from the surface of the frame 8 into the calcining kiln when the frame 8 is subsequently guided. After adjustment, it is convenient to add the material to be calcined from the top feed end of the frame box 2. When the guide rollers 23 in the base 22 inside the frame box 2 rotate under the operation of the drive motor, the conveyor belt 24 between the multiple sets of guide rollers 23 can operate synchronously and transport the material. At the same time, the multiple sets of rubber strips 25 on the surface of the conveyor belt 24 provide a certain limiting performance, making the conveyor belt 24 more stable. The material to be calcined is conveyed in a fixed manner. The material then slides down from the other end of the conveyor belt 24 and, under the limiting influence of the guide hopper 14, lands on the surface of the frame hopper 8. This causes the vibration motor 9 at the bottom of the frame hopper 8 to operate, vibrating the frame hopper 8. This vibration allows the material on the surface of the frame hopper 8 to slide stably down the frame hopper 8 into the calcining kiln, facilitating calcination and reducing the impact on the feeding equipment. Simultaneously, the buffer spring 5 between the pad 4 and the ear seat 6 supports the frame hopper 8, and the pad 10 at the bottom of the frame hopper 8 supports the buffer spring 5, ensuring that the vibration of the frame hopper 8 does not affect the straight arm 11. The straight arm 11 is conveniently hinged to the spring seat between the buffer spring 5 and the straight arm 11, so that the frame bucket 8 will not affect other structures when it vibrates. This allows the frame bucket 8 to stably convey materials under vibration, which is convenient for calcination. After the material is separated from the conveyor belt 24, the thrust spring 19 in the guide bucket 14 can push the support plate 17, which causes the support plate 17 to drive the brush 18 to brush the surface of the conveyor belt 24, which is convenient for cleaning the residual material attached to the surface of the conveyor belt 24. This allows the residual material to separate from the conveyor belt 24, so that the conveyor belt 24 can convey materials more stably, which is convenient for subsequent calcination.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
