Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a plate chain bucket elevator. Background Art

[0002] Plate chain bucket elevator is the most widely used vertical lifting equipment. It is favored for its good overall sealing and low environmental pollution. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials, and is therefore used in feed mills, flour mills, rice mills, and starch mills of various sizes.

[0003] When the existing plate chain bucket elevator is in use, it is difficult to screen the transported wheat seeds before processing and transportation. Dust or other particles and debris may enter the flour processing device, interfering with the subsequent production effect. The elevator needs to accurately transport the seeds to the processing device, and the feeding accuracy is required to be high. The discharge port is located at the top of the machine, and manual adjustment of the discharge port is required with the help of ladders or other auxiliary equipment. The process is dangerous and inefficient. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a plate chain bucket elevator comprises a plate chain bucket elevator body 1, a plurality of buckets 2 are installed inside the plate chain bucket elevator body 1 through a conveyor chain, and a feed assembly 3 is arranged at a rear end feed port of the plate chain bucket elevator body 1;

[0022] The feed assembly 3 includes a feed box 4, which is fixedly connected and installed at the feed port of the plate chain bucket elevator body 1. A double-layer filter screen 5 is movably installed at the center position of the feed box 4 through a number of return springs. A cam rotating rod 6 is rotatably installed inside the feed box 4 and below the double-layer filter screen 5, and the cam of the cam rotating rod 6 matches the double-layer filter screen 5. A striking motor is installed on one side of the feed box 4, and the driving shaft of the striking motor is connected to the cam rotating rod 6. An ash extraction pipe 8 is installed through the top of the feed box 4.

[0023] In the present embodiment, a debris collection box 7 is slidably installed inside the feed box 4 and below the double-layer filter screen 5. An elastic fastener matching the debris collection box 7 is movably connected to the lower side of one side of the feed box 4. The debris screened from the seeds will fall into the debris collection box 7. After a period of use, the debris collection box 7 is pulled out from the inside of the feed box 4 to facilitate centralized processing of the collected debris.

[0024] In this embodiment, the double-layer filter screen 5 is tilted and one end away from the plate chain bucket elevator body 1 is tilted. Polyurethane buffer pads are provided at the front and rear ends of the bottom of the double-layer filter screen 5. The inner wall of the feed box 4 is provided with a block that matches the polyurethane buffer pad, which facilitates the seeds to slide toward the plate chain bucket elevator body 1 during the screening process. The polyurethane buffer pad is provided to reduce the impact force caused by accidental collision.

[0025] In this embodiment, an observation window 9 is provided at an upper position at the rear end of the plate chain bucket elevator body 1, and a discharge port 10 is provided at a front position at the top of the plate chain bucket elevator body 1. The observation window 9 is provided to facilitate observation of the material lifting situation, and the discharge port 10 is provided to facilitate discharge of the material.

[0026] In this embodiment, the bottom end of the discharge port 10 is connected to a connecting pipe 11 through damping rotation, and a plurality of damping conveying pipes 12 are arranged below the connecting pipe 11. The plurality of damping conveying pipes 12 are interconnected through sealing connecting rings 13, and the damping conveying pipe 12 at the top is connected to the bottom end of the connecting pipe 11 through the sealing connecting ring 13. By turning the damping conveying pipe 12, it is convenient to adjust the damping conveying pipe 12 to a suitable angle, thereby improving the discharge effect.

[0027] In the present embodiment, a plurality of damping conveying pipes 12 are composed of a conveying hose and a plurality of damping rotating shafts. The plurality of damping conveying pipes 12 are detachably connected via a sealing connecting ring 13, and the damping conveying pipe 12 is detachably connected to the connecting pipe 11 via a sealing connecting ring 13. By pulling the damping conveying pipe 12, it is convenient to adjust the damping conveying pipe 12 to a suitable angle, thereby improving the material discharge effect and facilitating the extension or shortening of the damping conveying pipe 12. By adjusting, its length can be matched with the material discharge length.

[0028] It should be noted that the utility model is a plate chain bucket elevator. When in use, first, when feeding materials to an external flour processing device, the chain belt inside the plate chain bucket elevator body 1 can be started as needed, and the hopper 2 can be driven to rotate by the chain belt, and then the wheat seeds to be transported can be put into the feed box 4 as needed, because a double-layer filter screen 5 is installed in the feed box 4, and a cam rotating rod 6 matching the double-layer filter screen 5 is installed inside the feed box 4, and an ash extraction pipe 8 is provided at the top of the feed box 4; thus, when the seeds are fed, the striking motor is started to rotate the driving shaft to drive the cam rotating rod 6 to rotate, so that the cam strikes the double-layer filter screen 5, causing it to vibrate to filter the wheat seeds entering the feed box 4, so as to facilitate the screening of the tiny particles or broken seeds contained therein, and at the same time, when the seeds vibrate, the dust that may be adhered to the outside will be vibrated off;

[0029] By connecting the dust extraction pipe 8 to the external dust extraction pump, the dust vibrated out is extracted from the inside of the feed box 4, and then the seeds fall to the bottom of the plate chain bucket elevator body 1, and are transported to the processing device through the rotation of the hopper 2. Through the above steps, the purity of the seed feed can be improved, and the debris particles or shriveled tiny seeds can be reduced from being transported to the processing device, which is convenient for improving the subsequent production quality; and the debris screened from the seeds will fall into the debris collection box 7, and the debris collection box 7 is installed on the feed box 4 through an elastic fastener, so that after a period of use, the debris collection box 7 can be drawn out from the inside of the feed box 4 to clean the debris collection box 7;

[0030] At the same time, the seeds need to be filtered before they are fed into the plate chain bucket elevator body 1, which is convenient for limiting the amount of feeding and reducing the probability of excessive feeding causing material blockage in the lower section of the plate chain bucket elevator body 1;

[0031] When the unloading position needs to be adjusted, the connecting pipe 11 is installed at the unloading port 10 of the plate chain bucket elevator body 1 through the damping shaft, and the end of the connecting pipe 11 away from the unloading port 10 is connected to the damping conveying pipe 12 through the sealing connecting ring 13, and the damping conveying pipes 12 can be connected to each other for extension, so that multiple damping conveying pipes 12 can be connected to each other in advance to make the unloading length reach a suitable length. At the same time, because the damping conveying pipe 12 is composed of a conveying hose and a plurality of damping shafts, the damping conveying pipe 12 can be pulled to adjust the damping conveying pipe 12 to a suitable angle;

[0032] During the adjustment, the damping conveying pipe 12 can be held and rotated in the appropriate direction to facilitate the turning of the end of the damping conveying pipe 12 toward the feed port position of the external processing device, thereby improving applicability. During the adjustment process, the damping conveying pipe 12 has been extended to an appropriate length, and there is no need to climb back and forth with the help of tools for adjustment. The adjustment efficiency is high, eliminating certain safety hazards.
