Description

Technical Field

[0001] The utility model relates to the technical field of white rice sieving and feeding, in particular to a white rice grading sieve feeding structure. Background Art

[0002] The feeding structure of the rice grading screen, as its core component, is designed to smoothly and evenly guide the rice to be graded into the screen to ensure the smooth progress of the grading process. To achieve this goal, the feeding structure is often equipped with a well-designed hopper, whose shape and size are carefully determined according to the processing efficiency of the screen and actual production needs. The hopper has sufficient capacity to accommodate the appropriate amount of rice to be graded, and through its internal guide device, the rice is accurately guided to the screen surface of the grading screen, thereby achieving efficient and accurate grading operations.

[0003] However, in actual applications, dust often occurs in the feeding and discharging stages of the white rice grading screen, and this problem is particularly prominent in the field of grain processing. When the white rice to be screened enters the grading screen through the feed port, dust is easily generated during the feeding process due to the physical properties of the white rice itself, such as particle size, humidity, and surface roughness. These dusts are easily raised and spread into the working environment under the action of air flow or mechanical vibration, causing adverse effects on the working environment.

[0004] At the same time, in the discharging process, the sieved white rice is discharged from the discharging port according to different grades. However, in this process, due to the vibration of the grading screen and the influence of air flow, the dust in the graded white rice is also easily raised, further aggravating the deterioration of the working environment.

[0005] The dust problem of white rice dust not only reduces the cleanliness of the working environment, but also poses a potential threat to the health of operators. Working in a dusty environment for a long time, operators are prone to inhaling dust, which may cause respiratory diseases. In addition, dust may also irritate and damage the skin, causing adverse effects on the health of operators. Therefore, solving the dust problem in the feeding and discharging links of the white rice grading screen is of great significance to improving the working environment and protecting the health of operators.

DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1 - Figure 4 As shown, a white rice grading screen feeding structure comprises a base 1, a vibration box 2, a multi-stage screening assembly and a multi-stage discharge port, and is equipped with a feeding box 9. This design aims to achieve efficient grading and screening of white rice, and improve the screening effect through a refined feeding structure.

[0028] First, the vibration box 2 is firmly mounted on the base 1, and its cross section presents a unique "L"-shaped design. This design not only enhances the stability of the structure, but also makes the overall layout more reasonable. The upper end of the vibration box 2 is equipped with three-stage screening components, namely the first-stage screening component 3, the second-stage screening component 4 and the third-stage screening component 5. These components are arranged from the outside to the inside, and the adjacent two are connected by a buffer device to ensure the stability and continuity of the screening process.

[0029] Each level of screening assembly is provided with a corresponding discharge port, namely the first level discharge port 6, the second level discharge port 7 and the third level discharge port 8. When the vibration box 2 drives the multi-level screening assembly to vibrate and screen, white rice of different particle sizes will be separated through each level of the screen and discharged from the corresponding discharge port.

[0030] A feed box 9 is installed on the top of the base 1. This feed box 9 is fixed to the base 1 by bolts to ensure its stability and reliability. A feed port 10 is provided above the feed box 9 for adding white rice to be screened into the screening assembly.

[0031] In order to further improve the screening effect, a plurality of filter cartridges 11 are specially designed at the feed port 10. These filter cartridges 11 are mounted at the feed port 10, and rubber strips are provided at the contact end with the feed box 9 to ensure sealing. The inside of the filter cartridge 11 is provided with a trapezoidal filter cover 13 and a blocking cover 14 from top to bottom, with a gap between the two. When the white rice falls from the feed port 10, it will first pass through the filtering effect of the trapezoidal filter cover 13 and the blocking cover 14, effectively removing the dust in the white rice.

[0032] In order to facilitate the cleaning of the filtered white rice dust, drawer sockets 12 are also provided on both sides of the filter cartridge 11. Through these sockets, a drawer plug 15 can be inserted. The drawer plug 15 is divided into two parts: a long strip and an arc-shaped bending plate. The long strip is placed at the opening of the drawer socket 12 and is connected to the filter cartridge 11 by bolts. Multiple layers of adhesive paper 16 are installed on the arc-shaped bending plate, and these adhesive paper 16 can be fixed on the plug by bolts. When a certain amount of dust accumulates in the filter cartridge 11, the dust on the adhesive paper 16 can be easily cleaned by simply pulling the drawer plug 15 out of the socket.

[0033] Usage process: Install the vibration box 2 firmly on the base 1, and ensure that its "L"-shaped cross-section is stably placed. Check whether the first-stage screening assembly 3, the second-stage screening assembly 4, and the third-stage screening assembly 5 are arranged correctly, and whether the buffer device is firmly connected. Fix the feed box 9 to the top of the base 1 with bolts to ensure stability. Check whether the discharge ports at each level (first-stage discharge port 6, second-stage discharge port 7, and third-stage discharge port 8) are unobstructed.

[0034] Open the lid of the feed port 10 and pour the white rice to be screened into the feed box 9. Close the lid of the feed port 10 to ensure that the white rice will not leak out during the screening process.

[0035] Start the vibration box 2 to drive the multi-stage screening components to perform vibration screening. Observe the working status of the screening components at each level to ensure that the screening process is stable and continuous.

[0036] The white rice after each level of screening will be discharged through the first-level discharge port 6, the second-level discharge port 7 and the third-level discharge port 8. A collecting device is set at the discharge port to collect white rice of different particle sizes.

[0037] When filtering and collecting dust:

[0038] When the white rice falls from the feed port 10, it first passes through a plurality of filter cartridges 11. The trapezoidal filter cover 13 and the blocking cover 14 in the filter cartridge 11 perform preliminary filtering on the white rice to effectively remove dust therein.

[0039] The filtered dust will accumulate inside the filter cartridge 11. Check the dust accumulation of the filter cartridge 11 regularly. When the dust accumulation is large, open the drawer plug 12. Pull out the drawer plug 15, and the multi-layer sticker 16 pasted on the plug will be pulled out with the dust.

[0040] Clean the dust on the sticker 16, or replace the sticker 16 with a new clean sticker 16 for next use. The white rice grading screen feeding structure not only realizes efficient screening of white rice, but also effectively removes dust from the white rice, and realizes dust collection and cleaning through simple operation, thereby improving work efficiency and working environment quality.
