[0031] 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.

[0032] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A spiral metering and unloading device includes a base plate 1, a unloading cylinder 12 fixedly mounted on the top of the base plate 1, and a spiral conveying rod 14 rotatably connected inside the unloading cylinder 12. The spiral conveying rod 14 is a mechanical structure that pushes materials to achieve the purpose of conveying by spiral rotation. Simultaneously, the spiral conveying rod 14 can continuously convey materials through a stable rotation speed, thereby achieving accurate metering and quantitative discharge of materials. The spiral conveying rod 14 is an existing product.

[0033] Vertical rods are fixedly connected to both ends of the bottom of the unloading cylinder 12, and both vertical rods are fixedly connected to the top of the base plate 1. A discharge port is provided at the bottom of one end of the unloading cylinder 12. The height of the unloading cylinder 12 is increased by the vertical rods to facilitate the workers to receive the material at the discharge port.

[0034] The top of the unloading cylinder 12 is fixedly connected to the material box 15, and the top of the material box 15 is provided with a feeding port. The bottom of the material box 15 is funnel-shaped, and the bottom end of the material box 15 is fixedly connected to the unloading cylinder 12 through a pipe, so that the material in the material box 15 can be discharged into the unloading cylinder 12.

[0035] A connecting cylinder 20 is rotatably connected to the center of the material bin 15, and several stirring rods 21 are evenly fixed to the outer surface of the connecting cylinder 20. The stirring rods 21 can stir the material in the material bin 15, which facilitates material discharge.

[0036] The connecting cylinder 20 is rotatably connected to a telescopic rod 23, and the telescopic end of the bottom of the telescopic rod 23 is fixedly connected to a material guide rod 24.

[0037] A drive assembly is provided on the unloading cylinder 12, which drives the screw conveyor 14, the connecting cylinder 20 and the telescopic rod 23 to rotate.

[0038] The drive assembly includes a second motor 13, which is fixedly connected to the end of the unloading cylinder 12 away from the discharge port. The second motor 13 drives the screw conveyor 14 to rotate. The end of the screw conveyor 14 rotates through the end face of the unloading cylinder 12 and is then fixedly connected to the output end of the second motor 13. The outer surface of the screw conveyor 14 slides against the inner wall of the unloading cylinder 12 to facilitate the movement of the material by the screw conveyor 14.

[0039] An L-shaped bracket 28 is fixedly connected to the top of the material bin 15, and a rotating rod 16 is rotatably threaded through the bracket 28 via a bearing. The bearing increases the stability of the rotating rod 16.

[0040] The rotating rod 16 is horizontally arranged, and a belt drive component 17 is installed between one end of the rotating rod 16 and the screw conveyor rod 14. A first bevel gear 18 is fixedly connected to the other end of the rotating rod 16. The belt drive component 17 is a mechanical transmission that uses a flexible belt tensioned on a pulley to transmit motion or power. The belt drive component 17 is a commonly used mechanical transmission method and is existing technology. This allows the screw conveyor rod 14 to drive the rotating rod 16 to rotate via the belt drive component 17, causing the first bevel gear 18 to rotate.

[0041] A second bevel gear 19 is fixedly connected to the top of the connecting cylinder 20, and the second bevel gear 19 meshes with the first bevel gear 18. The rotation of the first bevel gear 18 will drive the second bevel gear 19 to rotate, causing the connecting cylinder 20 to rotate.

[0042] The top end of the telescopic rod 23 rotates through the second bevel gear 19 and is then rotatably connected to the bracket 28. A third bevel gear 22 is fixedly sleeved on the top end of the telescopic rod 23, and the third bevel gear 22 meshes with the first bevel gear 18. Rotation of the first bevel gear 18 will drive the third bevel gear 22 to rotate, causing the telescopic rod 23 to rotate.

[0043] The connecting cylinder 20 is equipped with a moving component. When the connecting cylinder 20 and the telescopic rod 23 rotate, the moving component drives the feed rod 24 to move up and down.

[0044] The movable component includes a movable groove 26, which is formed on the inner wall of the bottom end of the connecting cylinder 20. The movable groove 26 is arranged in an inclined annular shape.

[0045] A movable rod 25 is fixedly connected to the outer surface of the telescopic end of the telescopic rod 23, and the end of the movable rod 25 is slidably connected to the inside of the movable groove 26. When the end of the movable rod 25 slides in the movable groove 26, the movable rod 25 will move along the inclined direction of the movable groove 26.

[0046] All four corners of the bottom of the base plate 1 are fixedly installed with casters 11, which facilitate the movement of the base plate 1. Support plates 10 are raised and lowered at both ends of the base plate 1.

[0047] The support plates 10 are arranged horizontally, and anti-slip pads are fixedly installed at both ends of the bottom surface of the two support plates 10. The protective pads increase the stability of the support plates 10.

[0048] Limiting cylinders 9 are fixedly connected to the four corners of the bottom surface of the base plate 1. Limiting rods 27 are fixedly connected to both ends of the top surface of the two support plates 10. The limiting rods 27 correspond one-to-one with the limiting cylinders 9, and the top ends of the limiting rods 27 are slidably set inside the corresponding limiting cylinders 9. The support plates 10 are limited by the cooperation between the limiting rods 27 and the limiting cylinders 9, so that the support plates 10 can only move up and down.

[0049] A lifting assembly is provided at the bottom of the base plate 1, which drives the two support plates 10 to move up and down synchronously.

[0050] The lifting assembly includes a connecting rod 5, which is horizontally arranged. An inverted U-shaped mounting plate 3 is fixedly connected to the bottom of the base plate 1, and the connecting rod 5 is rotatably connected to the bottom of the mounting plate 3. A first motor 4 is fixedly connected to one end of the mounting plate 3, and the first motor 4 drives the connecting rod 5 to rotate. Both ends of the connecting rod 5 are fixedly fitted with first helical gears 6. The connecting rod 5 drives the two first helical gears 6 to rotate.

[0051] Sleeves 2 are fixedly connected to both ends of the bottom of the base plate 1, and the sleeves 2 are vertically arranged. The sleeves 2 correspond one-to-one with the support plate 10. The bottom ends of the two sleeves 2 are rotatably connected to second helical gears 7, and the second helical gears 7 correspond one-to-one with the first helical gears 6. The second helical gears 7 mesh with the corresponding first helical gears 6. The rotation of the first helical gears 6 will drive the second helical gears 7 to rotate.

[0052] Each second helical gear 7 has a threaded rod 8 internally connected. The top end of the threaded rod 8 is movably disposed within the corresponding sleeve 2, and the bottom end of the threaded rod 8 is fixedly connected to the top of the corresponding support plate 10. Due to the limiting effect of the support plate 10, when the second helical gear 7 rotates, it drives the threaded rod 8 to move upward or downward.

[0053] Working principle:

[0054] In use, the base plate 1 can be moved by the casters 11 to move the unloading cylinder 12 to the unloading point.

[0055] When the first motor 4 is started, its output shaft rotates clockwise. This drives the connecting rod 5 to rotate, causing the two first helical gears 6 to rotate.

[0056] The first helical gear 6 drives the corresponding second helical gear 7 to rotate, and the second helical gear 7 drives the threaded rod 8 to move downward, causing the support plate 10 to move downward. At the same time, the limiting rod 27 moves downward inside the limiting cylinder 9.

[0057] Until the support plate 10 moves to the ground, the support plate 10 supports the bottom of the base plate 1, increasing the stability of the base plate 1.

[0058] The material that needs to be discharged in a fixed quantity is fed into the inside of the material box 15, and the material will enter the discharge cylinder 12 through the bottom of the material box 15.

[0059] Start the second motor 13 to rotate the screw conveyor 14. The screw conveyor 14 will push the material to move and discharge the material for unloading.

[0060] The screw conveyor 14 drives the rotating rod 16 to rotate via the belt drive 17, causing the first bevel gear 18 to rotate. The first bevel gear 18 then drives the second bevel gear 19 and the third bevel gear 22 to rotate.

[0061] The second bevel gear 19 drives the connecting cylinder 20 and the stirring rod 21 to rotate, causing the stirring rod 21 to agitate the material in the material box 15.

[0062] The third bevel gear 22 drives the telescopic rod 23 to rotate. The telescopic rod 23 rotates inside the connecting cylinder 20, while the movable rod 25 on the telescopic end of the telescopic rod 23 slides inside the movable groove 26. Since the movable groove 26 is an inclined annular shape, the movable rod 25 moves up and down along the shape of the movable groove 26, thereby driving the material passage rod 24 to move up and down. This causes the material passage rod 24 to agitate the material at the connection between the material box 15 and the discharge cylinder 12, thus facilitating material passage and reducing the risk of blockage caused by material accumulation.

[0063] When the base plate 1 needs to be moved, the output shaft of the first motor 4 reverses. This causes the connecting rod 5 and the first helical gear 6 to rotate, and the second helical gear 7 to rotate, thereby driving the threaded rod 8 to move upward, and causing the support plate 10 to move upward, thus leaving the ground. At this time, the casters 11 support the base plate 1, thereby moving the base plate 1 via the casters 11.

[0064] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
