Description

Technical Field

[0001] This utility model relates to a rice polishing machine, specifically a top-suction polishing machine with manually adjustable self-locking feeding and an integrated screen frame. Background Technology

[0002] In today's world, increasing grain production and income has become a focal point of great concern. "Saving grain and reducing losses" is a consensus across the entire grain circulation industry chain. As a core piece of equipment in the grain processing field extending towards refined processing, how to improve rice grain quality, reduce energy consumption, and enhance the ease of operation, reliability, and precision of polishing machines in actual production has become an important issue for the grain machinery industry.

[0003] Traditional suction polishing machines suffer from structural and operational defects. Traditional polishing machines typically control feed output using a direct-push or rotary gate, which cannot stably adjust the feed rate, ensure uniform increase and decrease, or maintain the gate at each adjustment position, requiring additional tightening of set screws for locking. This cumbersome operation lacks precise adjustment and reliability, leading to significant current fluctuations, reduced polishing accuracy, and increased broken rice. Furthermore, existing top-suction polishing machines suffer from inconvenient maintenance and safety issues. Maintaining, cleaning, or replacing the screen requires disassembling the entire screen frame into four semi-circular tubular parts. Moving these parts from the machine to the floor is a 1.2-meter height, and each screen frame has considerable weight and dimensions, making it unsafe and inconvenient, requiring two people to complete. Reassembly and reinstallation are also cumbersome. Therefore, inventing a top-suction polishing machine with manually adjustable, self-locking feed and an integrated screen frame would be highly beneficial. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing rice milling machines by providing a top-suction polishing machine with manually adjustable self-locking feeding and an integrated screen frame. It overcomes the defects of existing top-suction polishing machines, such as large current fluctuations, reduced white rice polishing precision, and high broken rice rate due to inaccurate control of the feeding device.

[0005] The technical solution of this utility model is as follows: It includes a frame (1), a whitening chamber (2) fixed on the frame (1), a drive motor (3) mounted on one side of the frame (1), an upper suction hood (4) and a feeding device (5) mounted on the upper part of the frame (1), a bran separation hopper (15) mounted on the lower part of the whitening chamber (2), an integral screen frame (6) mounted inside the whitening chamber (2), and a manual adjustment self-locking device (7) mounted on the feeding device (5). The manual adjustment self-locking device (7) includes... Includes a rotating rod (16), with a rotating handle (17) at the top of the rotating rod (16), a rotating rod bracket (18) fixed at the front end of the rotating rod (16), a row of fan-shaped holes (19) on the support plate of the rotating rod bracket (18), a rotating arm (20) fixed at the rear of the rotating rod bracket (18), and spring balls (21) fixed on the rotating arm (20) at positions corresponding to the fan-shaped holes (19), and the rear end of the rotating rod (16) connected to the gate (24) of the feeding device (5).

[0006] A preferred embodiment of this invention is as follows: a coupling (22) is connected to the rear end of the rotating rod (16), the output shaft of the coupling (22) is connected to a sector gear (23), and the sector gear (23) meshes with a rack (25) fixed on the gate (24). The integral screen frame (6) includes a lower support (8) and an upper fixed seat (9). The lower support (8) is fixed with a left rotating arm (11) and a right rotating arm (12) via a rotating hinge (10). The left rotating arm (11) and the right rotating arm (12) are respectively fixed with a first integral screen frame (27) and a second integral screen frame (26) via a left rotating hinge (13) and a right rotating hinge (14). Screens are provided on both the first integral screen frame (27) and the second integral screen frame (26).

[0007] This invention adds a manual adjustment self-locking device, which can lock itself at any point within the adjustment range; it makes the feed rate adjustment more precise and easier to control; the constant feed rate makes the motor load current more stable and the equipment operation more stable; it has the advantages of small current fluctuation, high white rice polishing precision, and low broken rice rate, and also has the advantages of more convenient replacement of wear parts and cleaning and maintenance.
