Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a purification device in the grain processing production process. Background Technology

[0002] In the grain processing industry, vibrating screens, as key impurity removal equipment, play a crucial role in improving grain quality. However, existing vibrating screens have the following drawbacks in actual use: 1. In terms of vibration reduction, existing vibrating screens generally use springs for vibration damping. Since the spring stiffness is fixed after the equipment design and installation, it cannot be adjusted according to actual working conditions. Therefore, when the type and output of grains processed by the vibrating screen change, causing changes in the vibration frequency and amplitude generated by the vibration source, the springs cannot flexibly adapt to these changes. This results in vibration being transmitted to the support structure and surrounding equipment, which not only causes significant noise during equipment operation, interfering with the working environment, but also accelerates the wear of equipment parts, reduces equipment stability and service life, and increases maintenance costs; 2. The screen aperture of existing vibrating screens cannot be adjusted. Due to the differences in particle size and shape among different varieties of grains, a single-aperture screen cannot meet the impurity removal requirements of different types of grains. Once a new variety of grain needs to be processed, or new requirements are made for the impurity removal accuracy, the machine must be stopped to replace the screen. Since the screen replacement process is time-consuming and labor-intensive, the downtime of the equipment is long, thus affecting production efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see the appendix Figure 1 -Appendix Figure 7This utility model provides an embodiment of a grain processing equipment, comprising a support 1, vibration damping components 2, and a discharge tray 3. Multiple vibration damping components 2 are mounted on the support 1 and are mounted on the discharge tray 3. Each vibration damping component 2 includes a mounting base 21, which is fixedly connected to the support 1. An adjusting component 23 is threaded onto the mounting base 21. The adjusting component 23 has a mounting hole 25, in which a spring 26 is installed. One end of the spring 26 is disposed within the mounting base 21, and the other end of the spring 26 is fixedly connected to a connecting seat 27, which is fixedly connected to the discharge tray 3. Mounting seat 21 is used to install adjusting component 23, which is used to adjust the effective number of turns of spring 26. Spring 26 is used to dampen vibration of discharge tray 3. Connecting seat 27 is used to install spring 26. Discharge tray 3 is used for discharging miscellaneous grains. Mounting seat 21 has an internal thread 22, and adjusting component 23 has an external thread 24. The external thread 24 is threaded onto the internal thread 22. The internal thread 22 is used to mate with the external thread 24 to achieve the threaded connection between mounting seat 21 and adjusting component 23. Vibration motor 31 is fixedly connected to the lower surface of discharge tray 3, and frame 32 is fixedly connected to the upper surface of discharge tray 3. First screen 4 is fixedly connected to frame 32. The bottom end of first screen 4 A second screen 5 is provided, and a third screen 6 is provided at the bottom of the second screen 5. Both the third screen 6 and the second screen 5 are slidably connected within a frame 32. A vibration motor 31 is used to generate vibration force. The frame 32 is used to install the first screen 4, the second screen 5, and the third screen 6. The intersecting parts of the mesh openings of the first screen 4, the second screen 5, and the third screen 6 are the effective mesh openings used for screening grains. The mesh openings of the first screen 4, the second screen 5, and the third screen 6 are all rectangular. An adjustment component 7 is installed on both the third screen 6 and the second screen 5. The adjustment component 7 includes a limiting groove 71, a limiting block 72, a screw 73, a nut 74, a knob 75, and a through hole 76. Both the third screen 6 and the second screen 5 have limiting grooves 71. A limiting block 72 is rotatably connected in the limiting groove 71. A screw 73 is fixedly connected to the limiting block 72. A nut 74 is threaded onto the screw 73 and fixedly connected to the frame 32. The limiting groove 71 is used to install the limiting block 72. The screw 73 drives the third screen 6 and the second screen 5 through the limiting block 72. The nut 74 is used to cooperate with the screw 73 to realize the adjustment of the screw 73. A through hole 76 is opened on the frame 32 at the position corresponding to the screw 73. A knob 75 is fixedly connected to one end of the screw 73. The through hole 76 is used to accommodate the screw 73, and the knob 75 is used to rotate the screw 73.

[0022] Working principle: When using this utility model, firstly, adjust the aperture of the screen as needed by rotating knob 75. Knob 75 drives screw 73 to rotate within nut 74. Since nut 74 is fixed, screw 73 will move relative to nut 74. Through the limiting block 72 and the limiting groove 71, screw 73 drives the second screen 5 via the limiting block 72, thereby adjusting the size of the intersection of the second screen 5 and the first screen 4. By rotating another knob 75, the size of the intersection of the third screen 6 and the first screen 4 can be adjusted. Finally, the intersection of the three screen apertures is the actual aperture. Then, adjust the stiffness of spring 26 as needed by rotating adjusting part 23. The internal thread 22 engages with the external thread 24, causing the height of the adjusting component 23 on the mounting base 21 to change. The number of turns of the spring 26 between the adjusting component 23 and the connecting base 27 is the effective number of turns. After adjustment, the vibration motor 31 is started, which drives the discharge tray 3 to vibrate. The frame 32 on the discharge tray 3 vibrates accordingly, and the first screen 4, the second screen 5, and the third screen 6 on the frame 32 also vibrate. At this time, the grains can be poured into the starting end of the first screen 4 to screen and remove impurities. The bracket 1 is used to install the vibration damping component 2, which is used to dampen the vibration of the discharge tray 3. The mounting hole 25 is used to accommodate the spring 26, and the through hole 76 is used to accommodate the screw 73.
