[0002] Screw conveyor loader is a commonly used feeding device. The screw conveying rod inside the screw conveyor loader cooperates with the material conveying pipe to convey the material. Common causes of blockage of the screw conveyor loader include high material humidity, material agglomeration and other internal reasons and abnormal rotation of the screw conveying rod. Due to the gap between the screw conveying rod and the inner wall of the material conveying pipe, there are agglomerated materials or mixed granular impurities stuck between the screw conveying rod and the inner wall of the material conveying pipe, which hinders the smooth movement of the screw conveying rod, and also causes the screw conveyor loader to be blocked. In the current screw conveyor loader, the gap between the screw conveying rod and the inner wall of the material conveying pipe is uniform, making it difficult to discharge the stuck material from the gap during operation.

[0018] See also Figure 1-Figure 4The utility model provides the following technical solutions: a blocking-proof feeding mechanism, including a spiral conveying rod 1, an arc-shaped material conveying pipe 2 is sleeved on the outer side of the spiral conveying rod 1, a give-way arc plate 21 is installed above the arc-shaped material conveying pipe 2, a rotating material separation rod 3 is provided in the give-way arc plate 21, an upper material stop pad 4 is fixedly connected to the inner wall of the give-way arc plate 21, the upper material stop pad 4 is located in the clockwise direction of the rotating material separation rod 3, a side material stop pad 41 is provided below the upper material stop pad 4, and the side material stop pad 41 is located on one side of the spiral conveying rod 1.

[0019] In this embodiment: the axis of the spiral conveying rod 1 coincides with the axis of the arc-shaped material conveying pipe 2, the gap between the outer ring edge of the spiral conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2 is uniform, the gap between the give-way arc plate 21 and the inner wall of the smooth connecting plate 22 gradually increases and then gradually decreases. During the material conveying process, the material is conveyed to the rear end in the space inside the arc-shaped material conveying pipe 2. When there are no agglomerated particles and impurities stuck in the gap between the outer ring of the spiral conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2, the device operates normally. When there are agglomerated particles or impurities stuck in the gap between the outer ring of the spiral conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2, the agglomerated particles or impurities are transported through the arc-shaped material conveying pipe 2. After the inner wall of the conveying pipe 2 rotates for a certain angle within the corresponding range, it moves to the corresponding position of the yield arc plate 21. The yield arc plate 21 cooperates with the smooth connecting plate 22 to form a yield space above the spiral conveying rod 1. Under the large gap, the agglomerated particles or impurities are no longer squeezed in both directions. The agglomerated particles or impurities are shaken off under the action of gravity and are separated from the outer ring of the spiral conveying rod 1. When some agglomerated particles or impurities that are not shaken off under the action of gravity move to the corresponding position of the rotating separation rod 3, the rotating separation rod 3 separates the outer ring material of the spiral conveying rod 1 from the spiral conveying rod 1. The yield arc plate 21, the smooth connecting plate 22 and the rotating separation rod 3 cooperate to prevent the material from being stuck in the gap between the spiral conveying rod 1 and the arc-shaped material conveying pipe 2 for a long time. The normal rotation of the screw conveying rod 1 is hindered, causing the device to be blocked, and the upper material blocking pad 4 and the side material blocking pad 41 are further used to block the space between the inner wall of the give way arc plate 21 rotating in the clockwise direction away from the material rod 3 and the screw conveying rod 1, so as to prevent the material from entering the gap between the screw conveying rod 1 and the inner wall of the curved material conveying pipe 2 through the gradually shrinking space there, so that the screw conveying rod 1 can run stably and smoothly. When in use, the position of the opening of the connection between the give way arc plate 21 and the feeding bin 5 is controlled to limit the speed of material feeding, so as to prevent the material from completely filling the internal space of the curved material conveying pipe 2, the give way arc plate 21 and the smooth connecting plate 22, and keep the space corresponding to the give way arc plate 21 in a hollow state, and the material lifted by the rotation of the screw conveying rod 1 is in a suspended state. When the cam is in an empty state, the material will not be squeezed into the gap between the screw conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2 by a strong external force. The material that directly falls on the edge of the outer ring of the top of the screw conveying rod 1 will be blocked by the rotating separation rod 3. The angle difference between the outer ring of the screw conveying rod 1 and the rotating separation rod 3 will cause the corresponding positions of the outer ring of the screw conveying rod 1 and the rotating separation rod 3 to change continuously, so that the rotating separation rod 3 will exert a lateral force on the material, thereby driving the material to fall downward, and the rotating separation rod 3 will rotate under the external extrusion during use, and will not hinder the rotation of the screw conveying rod 1. The gap between the rotating separation rod 3 and the outer ring of the screw conveying rod 1 is smaller than the gap between the screw conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2.

[0020] A driving motor 11 is installed at one end of the spiral conveying rod 1, and the driving motor 11 is fixedly connected to the arc-shaped material conveying pipe 2; by providing the driving motor 11, the spiral conveying rod 1 can be driven to rotate to drive material conveying.

[0021] The bottom end of the give-way arc plate 21 is fixedly connected to a smooth connecting plate 22, which is fixedly connected to the arc-shaped material conveying pipe 2. The give-way arc plate 21 is smoothly connected to the inner wall of the arc-shaped material conveying pipe 2 through the smooth connecting plate 22; by setting the smooth connecting plate 22, the arc-shaped material conveying pipe 2 and the give-way arc plate 21 can be smoothly connected.

[0022] The bottom end of the arc-shaped material conveying pipe 2 is hingedly connected to a bottom discharge door 23, and the bottom discharge door 23 is locked with the arc-shaped material conveying pipe 2; after the device is used up and rotates at no load for a certain period of time, the bottom discharge door 23 is opened to discharge a small amount of material still remaining in the arc-shaped material conveying pipe 2, and when cleaning the device, the bottom discharge door 23 can be used as a liquid discharge port.

[0023] Both ends of the rotating material separation rod 3 are rotatably connected to a connecting shaft seat 31, and the two connecting shaft seats 31 are respectively fixedly connected to the side walls at both ends of the arc-shaped material conveying pipe 2; by setting the connecting shaft seat 31, the rotating material separation rod 3 can be supported, and the rotating material separation rod 3 is rotatably connected to the connecting shaft seat 31, so that the rotating material separation rod 3 can passively rotate when subjected to a force.

[0024] An elastic connecting block 42 is fixedly connected between the upper material stop pad 4 and the side material stop pad 41, and a wear-resistant protective layer 43 is fixedly connected to the outer walls of the side material stop pad 41 and the elastic connecting block 42; by setting the elastic connecting block 42, the side material stop pad 41 can swing when squeezed by the spiral conveying rod 1, and by setting the wear-resistant protective layer 43, the wear resistance of the side material stop pad 41 and the elastic connecting block 42 can be improved, thereby improving the service life.

[0025] The top of the give-way arc plate 21 is fixedly connected to the feed bin 5, the bottom end of the arc-shaped material conveying pipe 2 is fixedly connected to the discharge pipe 51, and the bottom end of the arc-shaped material conveying pipe 2 is fixedly connected to the support frame 6; the internal space of the feed bin 5 is connected to the internal space of the give-way arc plate 21, and the discharge pipe 51 is connected to the internal space of the arc-shaped material conveying pipe 2, and the support frame 6 plays a supporting role to lift the device.

[0026] The working principle and use process of the present invention are as follows: the material is transported to the rear end in the space inside the arc-shaped material conveying pipe 2. When there are no agglomerated particles and impurities stuck in the gap between the outer ring of the spiral conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2, the device operates normally. When there are agglomerated particles or impurities stuck in the gap between the outer ring of the spiral conveying rod 1 and the inner wall of the arc-shaped material conveying pipe 2, the agglomerated particles or impurities move to the corresponding position of the give-way arc plate 21 after running a certain angle through the corresponding range of the inner wall of the arc-shaped material conveying pipe 2. The give-way arc plate 21 cooperates with the smooth connecting plate 22. A clearance space is formed above the screw conveying rod 1. Under the large gap, the agglomerated particles or impurities are no longer squeezed in both directions. The agglomerated particles or impurities are shaken off under the action of gravity and lose contact with the outer ring of the screw conveying rod 1. When some agglomerated particles or impurities that are not shaken off under the action of gravity move to the corresponding position of the rotating separation rod 3, the rotating separation rod 3 separates the material on the outer ring of the screw conveying rod 1 from the screw conveying rod 1, avoiding the material from being stuck in the gap between the screw conveying rod 1 and the arc-shaped material conveying pipe 2 for a long time, hindering the normal rotation of the screw conveying rod 1 and causing blockage of the device.
