Technical Field

[0001] This utility model relates to the field of grain drying technology, specifically to a grain drying tower feeding device that prevents grain from piling up. Background Technology

[0002] During grain drying, grain is typically fed into a grain drying tower via a feeding device, and then dried by the drying tower, thus facilitating grain storage and use.

[0003] To prevent grain from piling up when it is added to the grain drying tower, existing feeding devices usually have guide scrapers to scrape the grain and facilitate its discharge into the drying tower. However, dust often accumulates inside the feeding device when the grain is added. Over time, this dust adheres to the inside of the feeding device, causing scaling and affecting the flow of the grain. This hinders the rapid discharge of the grain and affects the feeding of the grain drying tower. Utility Model Content

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] like Figures 1-4 As shown, a feeding device for a grain drying tower to prevent grain accumulation includes a distribution box 1, a detachable box cover 2 on the top of the distribution box 1, and multiple guide pipes 6 connected to the bottom of the distribution box 1. A feeding hopper 3 is provided at the top of the box cover 2. Supports 5 are fixed on both sides of the distribution box 1 to install and fix it to the grain drying tower. The distribution box 1 is also provided with a stirring structure 7 to agitate the grain. Specifically, for ease of illustration, there are four guide pipes 6 in this application, and the four guide pipes 6 are arranged in a ring array. The mixing structure 7 includes a shaft 75 rotatably installed inside the distribution box 1, a sleeve 76 is installed on the shaft 75, and mixing plates 73 are fixed on both sides of the sleeve 76; the mixing structure 7 also includes a motor 71 fixed to the bottom of the distribution box 1, and the main shaft of the motor 71 is connected to the bottom end of the shaft 75. It also includes a cleaning and scraping assembly for cleaning the inner wall of the material distribution box 1. The cleaning and scraping assembly includes a scraper 72 mounted on the shaft 75 and a cleaning scraper 74 disposed on the side of the two stirring plates 73 away from the sleeve 76. The scraper 72 is located below the stirring plates 73, and when the shaft 75 drives the stirring plates 73 to rotate, it can simultaneously drive the scraper 72 and the cleaning scraper 74 to rotate along the inner bottom and inner wall of the material distribution box 1, respectively.

[0017] In use, the distribution box 1 is first installed on the top of the grain drying tower through the bracket 5, and the four guide pipes 6 are connected to the feed inlet on the grain drying tower respectively. Then, when the grain is added into the feed hopper 3, the grain falls into the distribution box 1 through the feed hopper 3. Subsequently, the grain flows into the grain drying tower through the four guide pipes 6 respectively, thereby realizing the diversion of grain, avoiding grain accumulation, and facilitating the even addition of grain into the grain drying tower. Furthermore, during the grain diversion process, the motor 71 can drive the shaft 75 to rotate, so that the shaft 75 drives the stirring plate 73 to rotate through the sleeve 76, thereby stirring the grain in the distribution box 1. This can further prevent blockage inside the distribution box 1 and facilitate uniform feeding of the grain drying tower. Meanwhile, when the grain is diverted into the grain drying tower, the shaft 75 will drive the scraper 72 to rotate along the bottom of the inner side of the distribution box 1 to clean the bottom of the inner side of the distribution box 1. The stirring plate 73 will drive the cleaning scraper 74 to rotate along the inner wall of the distribution box 1 to clean the inner wall of the distribution box 1. This will clean the inside of the distribution box 1, prevent the accumulation of dust and scale inside the distribution box 1, and help ensure the normal use of the distribution box 1. It will also facilitate the uniform feeding of the grain drying cylinder and achieve efficient drying of the grain.

[0018] Specifically, regarding how to quickly disassemble and assemble the aforementioned box cover 2, such as... Figures 1-3 As shown, a connector 4 is also provided between the material distribution box 1 and the box cover 2. The connector 4 includes an upper connecting ring 41 installed at the bottom of the box cover 2, a lower connecting ring 42 fixed at the top of the material distribution box 1, and a fastening bolt 43 for fastening the upper connecting ring 41 and the lower connecting ring 42.

[0019] When the cover 2 needs to be removed, the fastening bolts 43 can be removed first, and then the cover 2 can be pulled upward to remove the cover 2 from the top of the material distribution box 1, thereby completing the removal of the cover 2. This facilitates the cleaning of the inside of the material distribution box 1 and the maintenance of various components.

[0020] In another embodiment, such as Figures 4-8 As shown, the mixing plate 73 is also provided with a fastener 77 for quick assembly and disassembly of the cleaning scraper 74. The fastener 77 includes an insert strip 771 installed on one side of the cleaning scraper 74. The mixing plate 73 has an insert groove 775 on the side adjacent to the cleaning scraper 74 for the insert strip 771 to insert into. The mixing plate 73 also has wedge-shaped holes 772 that are perpendicular to the insert groove 775. A wedge-shaped block 773 is inserted into the wedge-shaped hole 772. The insert strip 771 has a through hole 774 for the wedge-shaped block 773 to pass through.

[0021] When the scraper plate 74 needs cleaning or replacement, the cover 2 can be removed from the distribution box 1 first, then the wedge block 773 can be pulled out from the wedge hole 772, and then the scraper plate 74 can be pulled upward so that the connector strip 771 can be moved out from the connector groove 775 to disassemble the scraper plate 74. After cleaning or replacement, the scraper plate 74 can be inserted into one side of the mixing plate 73 with the cooperation of the connector strip 771 and the connector groove 775. Then the wedge block 773 can be inserted into the wedge hole 772 to fix the connector strip 771 and the mixing plate 73, thus completing the installation of the scraper plate 74. This allows for quick disassembly and assembly of the scraper plate 74, facilitating regular cleaning or replacement of the scraper plate 74. This helps ensure the cleaning effect of the scraper plate 74 on the inside of the distribution box 1, so as to facilitate the subsequent use of the distribution box 1 and realize the normal feeding of the grain drying tower.

[0022] Furthermore, such as Figure 5 , Figure 7 and Figure 8 As shown, a tenon block 776 is also provided on the top of the through hole 774, and a tenon groove 777 is provided on the wedge block 773 for the tenon block 776 to be tenoned.

[0023] When the wedge block 773 is inserted into the wedge hole 772, the tenon block 776 will be inserted into the tenon groove 777 to tenon the wedge block 773 and the wedge hole 772, thereby increasing the stability of the wedge block 773 and the wedge hole 772 during insertion, which is beneficial to the stable connection of the cleaning scraper 74.

[0024] Furthermore, such as Figure 8 As shown, a limiting strip 778 is also installed in the tenon groove 777, and a limiting groove that matches the limiting strip 778 is provided at the bottom of the tenon block 776.

[0025] When the tenon block 776 is inserted into the tenon groove 777, the limiting strip 778 can be inserted into its corresponding limiting groove to limit the distance between the tenon block 776 and the tenon groove 777, thereby facilitating the stable and quick insertion of the tenon block 776 into the tenon groove 777 and ensuring a stable tenon joint between the tenon block 776 and the tenon groove 777.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
