A phosphate ore feeder

Abstract

This utility model discloses a phosphate rock feeder, including a frame, a screening frame, and a vibrating motor. The screening frame is disposed inside the frame and extends to its left side, while the vibrating motor is disposed on the right side of the screening frame. It also includes a guide plate, a moving frame, a bottom frame, and multiple cleaning rods. The guide plate is disposed directly below the screening frame and extends to the right side of the frame. The moving frame is slidably disposed inside the frame. This utility model, by setting the frame and screening frame in an inclined position, facilitates material discharge. During cleaning of the screening frame, a push-out component pushes out multiple cleaning rods, and a moving component drives the moving frame to move the cleaning rods left and right. The vibrating motor causes the screening frame to vibrate continuously up and down. During this process, the cleaning rods insert into the screening frame through the mesh, pushing out the phosphate ore within the mesh. This improves the feeder's working efficiency and extends the service life of the screening frame.

Description

Technical Field

[0001] This utility model relates to the field of ore processing technology, and in particular to a phosphate ore feeder. Background Technology

[0002] In the process of ore processing, ore raw materials need to be transported to crushers or screening machines. Generally, a conveyor belt is used as a feeding device to feed the crusher and screening machine. The conveyor belt is set at an incline on the support to transport the raw materials from the bottom to the top, thereby achieving the feeding effect.

[0003] In existing phosphate ore feeders, the phosphate ore varies in size during transport and needs to be screened. Some ores with a volume similar to the screen mesh size can easily clog the mesh. This clogging directly reduces the screening area and the throughput of phosphate ore, thereby reducing the overall processing capacity of the screening system. The clogged mesh also causes the screen to bear greater pressure and friction in localized areas, thus accelerating screen wear and shortening its service life. Therefore, a new phosphate ore feeder is proposed to solve these problems. Utility Model Content

[0004] This utility model provides a phosphate ore feeder, including a frame, a screening frame, and a vibrating motor. The screening frame is disposed inside the frame and extends to its left side. The vibrating motor is disposed on the right side of the screening frame. It also includes a guide plate, a moving frame, a bottom frame, and multiple cleaning rods. The guide plate is disposed directly below the screening frame and extends to the right side of the frame. The moving frame is slidably disposed inside the frame. The bottom frame is fixedly connected to the bottom end of the moving frame. An ejector assembly is disposed inside the bottom frame to eject the multiple cleaning rods from the moving frame. The dimensions of the multiple cleaning rods are adapted to the size of the mesh of the screening frame. A drive assembly is disposed inside the frame to drive the moving frame to move left and right.

[0005] Preferably, the ejection assembly includes a rotating rod, two first threaded rods, two first bevel gears, two second bevel gears, and a movable plate. One end of the rotating rod is rotatably connected to the right side wall of the bottom frame, and the other end extends to its left side. One end of each of the two first threaded rods is rotatably connected to the top of the movable frame, and the other end extends into the bottom frame. Both first bevel gears are coaxially fixedly sleeved on the rotating rod. The two second bevel gears are coaxially fixedly sleeved on the two first threaded rods and mesh with the two first bevel gears respectively. The movable plate is threadedly connected to the two first threaded rods. A plurality of cleaning rods are connected to the top of the movable plate and extend to the top of the movable frame.

[0021] like Figure 1-4 As shown, the present invention proposes a phosphate ore feeder, including a frame 1, a screening frame 2, and a vibrating motor 3. The screening frame 2 is disposed inside the frame 1 and extends to its left side. The vibrating motor 3 is disposed on the right side of the screening frame 2. It also includes a guide plate 4, a moving frame 5, a bottom frame 6, and multiple cleaning rods 7. The guide plate 4 is disposed directly below the screening frame 2 and extends to the right side of the frame 1. The moving frame 5 is slidably disposed inside the frame 1. The bottom frame 6 is fixedly connected to the bottom end of the moving frame 5. The bottom frame 6 is provided with an ejector assembly that ejects multiple cleaning rods 7 from the moving frame 5. The size of the multiple cleaning rods 7 is adapted to the size of the mesh of the screening frame 2. The frame 1 is provided with a drive assembly that drives the moving frame 5 to move left and right.

[0022] In this invention, the left sides of both the frame 1 and the screening frame 2 are inclined downwards, and the right side of the guide plate 4 is inclined downwards. Vibration is generated by the vibration motor 3, causing the screening frame 2 and the guide plate 4 to vibrate together. The right side of the frame 1 has two outlets, and the guide plate 4 extends out from the outlets to facilitate separate discharge from the left and right sides. The front of the frame 1 is provided with a European-style frame door. When the moving frame 5 and the bottom frame 6 are at the rightmost position inside the frame 1, the push-out component can be driven to push out multiple cleaning rods 7, and then the frame door can be closed. When it is necessary to clean the mesh of the screening frame 2, the multiple cleaning rods 7 are first pushed out, and then the vibration motor 3 is started to make the screening frame 2 vibrate up and down continuously. Then the drive component is started to drive the multiple cleaning rods 7 to move to the left. When the screening frame 2 moves downwards, the cleaning rods 7 are inserted into the mesh, pushing out the phosphate rock stuck in the mesh and exporting it along the inclined screening frame.

[0023] In an optional embodiment, the ejection assembly includes a rotating rod 81, two first threaded rods 82, two first bevel gears 83, two second bevel gears 84, and a movable plate 85.

One end of each of the two first threaded rods 82 is rotatably connected to the top of the movable frame 5, and the other end extends into the bottom frame 6. Both first bevel gears 83 are coaxially fixedly sleeved on the rotating rod 81. The two second bevel gears 84 are coaxially fixedly sleeved on the two first threaded rods 82 and mesh with the two first bevel gears 83 respectively. The movable plate 85 is threadedly connected to the two first threaded rods 82. A plurality of cleaning rods 7 are connected to the top of the movable plate 85 and extend above the movable frame 5.

[0024] It should be noted that when the frame door is opened, the rotating rod 81 is turned to drive the two first threaded rods 82 to rotate through the two first bevel gears 83 and the two second bevel gears 84, so that the moving plate 85 drives the multiple cleaning rods 7 to move.

[0025] In an optional embodiment, the left and right sides of the movable frame 5 are fixedly connected to fixed plates, which are slidably connected to the left and right walls of the frame 1, respectively.

The front fixing plate is threadedly connected to the second threaded rod 92.

[0027] It should be noted that a support rod is fixedly connected between the left and right walls of the frame 1, and the rear fixed plate is slidably sleeved on the support rod. The starting motor 91 drives the second threaded rod 92 to rotate, thereby driving the moving frame 5 to move.
