[0022] See also Figure 1 and Figure 2 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment, Figure 2 It is a cross-sectional view of the overall internal structure of the first embodiment.

[0023] The utility model provides a belt feeder: including a housing 101, a bracket 102, a feed pipe 103, a guide plate 100, a discharge pipe 104, a conveyor belt 105, two rotating rollers 106 and a support assembly, wherein the support assembly includes a U-shaped frame 107, a bidirectional threaded rod 108, two sleeves 109, two connecting rods 110, a driving member, a lifting plate 113, a plurality of transmission rollers 114 and a plurality of telescopic rods 115, and the driving member includes a motor frame 111 and a driving motor 112. The above-mentioned solution solves the problem that the middle part of the existing conveyor belt is suspended in the air, the heavier material causes the conveyor belt to sink, the conveyor belt is easily damaged, and its service life is affected.

[0024] According to this specific embodiment, the shell 101 is arranged above the bracket 102, the feed pipe 103 is arranged above the shell 101, the discharge pipe 104 is arranged below the shell 101, the guide plate 100 is arranged in the discharge pipe 104, the conveyor belt 105 is sleeved on the outer walls of the two rotating rollers 106, and the support assembly is arranged in the conveyor belt 105. When conveying materials, the support assembly is first used to support the conveyor belt 105 to prevent the conveyor belt 105 from falling due to excessive weight of the materials, to prevent the conveyor belt 105 from being damaged, and to increase the service life. By adding the materials through the feed pipe 103, the materials will then fall on the conveyor belt 105, and the conveyor belt 105 is driven to move by driving the rotating rollers 106, and the conveyor belt 105 transports the materials to the discharge pipe 104 for discharge.

[0025] Wherein, the U-shaped frame 107 is fixed to the shell 101 and is located in the conveyor belt 105, both ends of the bidirectional threaded rod 108 are rotatably connected to the U-shaped frame 107, the two sleeves 109 are sleeved on the outside of the bidirectional threaded rod 108, and are threadedly matched with the bidirectional threaded rod 108, the lifting plate 113 is arranged above the U-shaped frame 107, and both ends of each connecting rod 110 are rotatably connected to the sleeve 109 and the lifting plate 113 respectively, the driving member is connected to the bidirectional threaded rod 108 and is located on the outer side wall of the U-shaped frame 107, and a plurality of transmission rollers 114 are evenly distributed above the lifting plate 113. When conveying materials, the driving member is started, and the driving member controls the bidirectional threaded rod 108 to rotate in the U-shaped frame 107. The two sleeves 109 are threadedly matched with the two-way threaded rod 108, and the two sleeves 109 will move relatively on the two-way threaded rod 108. At this time, the stretching of the two connecting rods 110 will drive the lifting plate 113 to move upward until the multiple transmission rollers 114 on the lifting plate 113 are in contact with the bottom of the conveyor belt 105. The multiple transmission rollers 114 are evenly arranged in sequence under the conveyor belt 105, which can stably support the conveyor belt 105. Subsequently, the material passes through the feed pipe 103 and enters the top of the conveyor belt 105, driving the rotating roller 106 to rotate. The conveyor belt 105 operates to feed the material into the discharge pipe 104. In the above manner, the conveyor belt 105 can be supported to prevent the conveyor belt 105 from sinking and being damaged, thereby improving its service life.

[0026] Secondly, the two ends of each telescopic rod 115 are respectively connected to the U-shaped frame 107 and the lifting plate 113. When the lifting plate 113 is controlled to be raised or lowered, the multiple telescopic rods 115 will be extended and retracted as the lifting plate 113 moves. The arrangement of the multiple telescopic rods 115 can improve the stability of the lifting plate 113 when it moves.

[0027] At the same time, the motor frame 111 is fixedly connected to the U-shaped frame 107 and is located on the outer wall of the U-shaped frame 107. The drive motor 112 is fixedly connected to the motor frame 111. The output end of the drive motor 112 is connected to the bidirectional threaded rod 108. The motor frame 111 fixes and supports the drive motor 112 on the outside of the U-shaped frame 107. The drive motor 112 controls the bidirectional threaded rod 108 to rotate in the U-shaped frame 107.

[0028] When conveying materials, the driving motor 112 on the motor frame 111 is started, and the driving motor 112 controls the bidirectional threaded rod 108 to rotate in the U-shaped frame 107. Since the two sleeves 109 are threadedly matched with the bidirectional threaded rod 108, the two sleeves 109 will move relatively on the bidirectional threaded rod 108. At this time, the two connecting rods 110 are stretched to drive the lifting plate 113 to move upward, and the multiple telescopic rods 115 will stretch and retract with the movement of the lifting plate 113 until the lifting plate 113 is lifted. The multiple drive rollers 114 on the plate 113 are in contact with the bottom of the conveyor belt 105, and the multiple drive rollers 114 are evenly arranged in sequence under the conveyor belt 105, which can provide stable support for the conveyor belt 105. Then, the material passes through the feed pipe 103 and enters the top of the conveyor belt 105, driving the rotating roller 106 to rotate, and the conveyor belt 105 operates to deliver the material into the discharge pipe 104. In the above manner, the conveyor belt 105 can be supported, preventing the conveyor belt 105 from sinking and being damaged, thereby increasing its service life.

[0032] The scraping assembly is connected to the discharge pipe 104 and is located in the shell 101. By setting the scraping assembly, the scraping assembly can clean the impurities on the surface of the conveyor belt 105 to avoid the impurities from being retained on the surface of the conveyor belt 105, which is conducive to cleaning the conveyor belt 105.

[0033] The movable plate 201 is movably connected to the discharge pipe 104 and is located in the discharge pipe 104. The scraper 202 is fixedly connected to the movable plate 201 and is located below the conveyor belt 105. The two ends of the torsion spring 203 are respectively connected to the movable plate 201 and the discharge pipe 104. The material enters the discharge pipe 104 through the conveyor belt 105. When there are impurities on the surface of the conveyor belt 105, the scraper 202 will contact the impurities on the conveyor belt 105 and scrape the impurities. The movable plate 201 will rotate in the discharge pipe 104, and the torsion spring 203 will be deformed as the movable plate 201 rotates. The resilience of the torsion spring 203 will reset the movable plate 201, so that the scraper 202 can continuously clean the surface of the conveyor belt 105, and the cleaned impurities will be discharged through the discharge pipe 104. In the above manner, the impurities on the surface of the conveyor belt 105 can be cleaned to prevent the impurities from being retained on the surface of the conveyor belt 105, which is conducive to cleaning the conveyor belt 105.

The return spring 204 expands and contracts as the movable plate 201 rotates. The return spring 204 can increase the return effect of the movable plate 201, which is beneficial for the scraper 202 to clean the surface of the conveyor belt 105.

[0035] The material enters the discharge pipe 104 through the conveyor belt 105. When there are impurities on the surface of the conveyor belt 105, the scraper 202 will contact the impurities on the conveyor belt 105 and scrape the impurities. At the same time, the movable plate 201 will rotate in the discharge pipe 104, and the torsion spring 203 and the return spring 204 will deform as the movable plate 201 rotates. In addition, the resilience of the torsion spring 203 and the return spring 204 resets the movable plate 201, so that the scraper 202 can continuously clean the surface of the conveyor belt 105, and the cleaned impurities will be discharged through the discharge pipe 104. In the above manner, the impurities on the surface of the conveyor belt 105 can be cleaned to prevent the impurities from being retained on the surface of the conveyor belt 105, which is conducive to cleaning the conveyor belt 105.
