Description

Technical Field

[0002] In the grain processing industry, vibrating screens are a commonly used piece of equipment. Their main function is to screen grains to remove impurities and broken grains, thereby improving the quality and purity of the grains. However, existing vibrating screens have some problems that urgently need to be solved in the feeding process.

[0003] Currently, many vibrating screens used for grain screening struggle to achieve uniform material distribution during the feeding process. Traditional feeding methods often result in grain concentrating in localized areas of the screen surface, leading to a reduction in the effective utilization area of ​​the screen. This results in excessively thick grain accumulation in some areas of the screen, while other areas are under-fed. This not only reduces screening efficiency but also affects the screening effect, preventing the effective removal of some impurities and substandard particles, thus impacting the final grain quality.

Detailed Implementation

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1 to 4 As shown in the figure, the present invention provides a vibrating screen uniform material distribution device for grain screening, comprising, The vibration mechanism 100 includes a base plate 101, a support plate 102 is provided on the top of the base plate 101, a feeding box 103 is provided on the top of the support plate 102, a feeding plate 104 is provided at the bottom of the feeding box 103, and a vibration assembly 105 is provided at the bottom of the feeding plate 104. The fabric feeding mechanism 200 includes a fixed rod 201 disposed on the top of the feeding box 103. The inner wall of the fixed rod 201 is provided with a plurality of support rods 202. The inner wall of the plurality of support rods 202 is fixedly connected to an output motor 203. The output end of the output motor 203 is provided with a fabric feeding assembly 204.

[0019] refer to Figure 1 , 2The vibration assembly 105 includes a positioning plate 105a fixedly connected to the inner wall of the support plate 102. Two sets of damping components 106 are provided at each of the four ends of the top of the positioning plate 105a. A damping plate 105b is fixedly connected to the top of the two damping components 106. A vibration motor 105c and a vibration plate 105d are respectively provided on the inner wall and top of the damping plate 105b. The vibration plate 105d is located at the bottom of the feed plate 104. The damping component 106 includes a damper 106a and a damping spring 106b. The opposite side of the damper 106a is fixedly connected to the top of the positioning plate 105a and the bottom of the damping plate 105b respectively. The damping spring 106b is sleeved on the outside of the damper 106a.

[0020] The above solution allows the vibration generated by the vibration motor 105c to be transmitted to the vibration plate 105d via the damping plate 105b, so that the grain after being fed by the feeding plate 104 vibrates evenly, which is beneficial for the even feeding of grain.

[0021] refer to Figure 1 , 3 The fabric assembly 204 includes a rotating ring 204a that is connected to the output end of the output motor 203. A rotating plate 204b is provided at the bottom of the rotating ring 204a, and several fabric plates 204c are provided on the outer side of the rotating plate 204b.

[0022] The above scheme is adopted: the rotating ring 204a connected to the output end of the output motor 203 drives the rotating plate 204b and the material distribution plate 204c to rotate. The rotating material distribution plate 204c can push the grain in the feeding box 103 to the four sides to achieve uniform material distribution, so that the grain can fall more evenly on the vibrating screen, thereby improving screening efficiency and quality.

[0023] refer to Figure 1 , 4 A fixing block 301 is fixedly connected to the outside of the fixing rod 201. A plug-in rod 302 is provided at the bottom of the fixing block 301. The bottom of the plug-in rod 302 extends through to the bottom of the plug-in block 303. The rear side of the plug-in block 303 is fixedly connected to the front side of the feeding box 103.

[0024] The above solution is adopted: the fixing block 301 on the outside of the fixing rod 201 is connected to the feeding box 103 through the plug rod 302 and the plug block 303. This connection method facilitates the installation and disassembly of the fabric feeding mechanism 200, and makes it convenient to repair and replace the fabric feeding mechanism 200.

[0025] refer to Figure 1 , 4 The front side of the plug-in block 303 is provided with a pull groove 304, and a pull rod 305 is slidably connected to the surface of the pull groove 304. A limiting block 306 is provided on the surface of the pull rod 305, and the front side of the limiting block 306 is slidably connected to the inner wall of the plug-in block 303.

[0026] The above solution facilitates operation through the pull groove 304 and pull rod 305 on the front side of the plug-in block 303. Pulling the pull rod 305 can move the limiting block 306, thereby fixing and loosening the plug-in rod 302, which facilitates the installation and disassembly of the fabric mechanism 200.

[0027] refer to Figure 1 , 3 4. A positioning rod 307 is provided on the inner wall of the plug-in block 303. The surface of the positioning rod 307 is in contact with the surface of the positioning groove 308. The positioning groove 308 is opened on the outer side of the plug-in rod 302. A tension spring 309 is provided on the right side of the positioning rod 307. The right side of the tension spring 309 is fixedly connected to the inner wall of the plug-in block 303. A connecting plate 310 is provided at the bottom of the positioning rod 307. Connecting grooves 311 are opened on both the front and rear sides of the connecting plate 310. The inner wall of the connecting groove 311 is in contact with the outer side of the pull rod 305.

[0028] The above solution allows for accurate positioning of the insertion rod 302 through the cooperation of the positioning rod 307 and the positioning groove 308, ensuring the stability of the fabric mechanism 200 installation. The tension spring 309 enables the positioning rod 307 to remain in a fixed position when not subjected to external force, thus achieving automatic reset. The cooperation between the connecting plate 310 and the connecting groove 311 and the pulling rod 305 allows the positioning rod 307 to move when the pulling rod 305 is pulled, thereby separating the positioning rod 307 from the positioning groove 308 and facilitating the disassembly of the fabric mechanism 200.

[0029] refer to Figure 1 , 4 The inner wall of the plug block 303 is fixedly connected to the travel plate 312. The top of the travel plate 312 is provided with a travel groove 313. The surface of the travel groove 313 is slidably connected to the travel column 314. The top of the travel column 314 is fixedly connected to the bottom of the positioning rod 307.

[0030] By adopting the above solution, the movement of the positioning rod 307 can be restricted and guided by the setting of the stroke plate 312, the stroke groove 313 and the stroke column 314, so as to ensure the stability and accuracy of the positioning rod 307 during the movement process, thereby ensuring the smooth installation and disassembly of the fabric feeding mechanism 200.

[0031] The working principle of this utility model: When using this vibrating screen; When the grain enters the feeding box 103, the spreading mechanism 200 starts to work. The output motor 203 on the inner wall of the fixed rod 201 starts, and its output end drives the rotating ring 204a. The rotating plate 204b at the bottom of the rotating ring 204a and the spreading plate 204c on the outside rotate accordingly, pushing the grain in the feeding box 103 to the surrounding areas to achieve initial uniform spreading. Next, the grain falls through the feeding plate 104. At this time, the vibration mechanism 100 comes into play, and the vibration motor 105c in the vibration assembly 105 starts, driving the vibration plate 105d to vibrate. The vibration plate 105d transmits the vibration to the feeding plate 104, causing the feeding plate 104 to vibrate evenly, ensuring that the grain falls smoothly and evenly from the feeding plate 104 and lands on the top of the vibration plate 105d. Through the vibration of the vibration motor 105c, the grain can fall evenly. Meanwhile, the damping component 106 in the vibration assembly 105, namely the damper 106a and the damping spring 106b, reduces the impact of the vibration generated by the vibration motor 105c on components such as the support plate 102. If the fabric mechanism 200 needs to be repaired or replaced, the pulling rod 305 in the front pulling groove 304 of the plug-in block 303 can be pulled to move the positioning rod 307, so that it is separated from the positioning groove 308 on the outside of the plug-in rod 302, thereby disassembling the fabric mechanism 200.

[0032] In summary, this vibrating screen uniform material distribution device for grain screening addresses the issue that traditional vibrating screens tend to concentrate grain in a certain area during feeding, resulting in poor screening efficiency. This device, through a motor driving a rotating ring, rotating plate, and material distribution plate in the material distribution mechanism, can evenly distribute the grain in the feeding box to all sides, ensuring preliminary uniform distribution of the grain before it enters the vibrating screen, thereby improving screening efficiency and quality.
