Description

Automatic screening device for preventing material spillage during fermentation of fermented rice. Technical Field

[0001] This utility model relates to the field of fermentation agent production and manufacturing technology, and in particular to an automatic screening device for preventing material from falling into fermented glutinous rice fermentation agents. Background Technology

[0002] In the production process of fermented rice wine starter, the starter needs to be screened after inoculation to ensure that the volume of starter is uniform, so as to stably control the mycelium content to remain at the same average level after processing in the fermentation drying room. Traditionally, manual loading and unloading of materials is mainly relied on, and subsequent counting and spreading also rely on manual operation.

[0003] A patent application for a screening device for fermented rice wine starter with Chinese patent number CN202222419141.X solves the problem of subsequent spreading and counting of starter by optimizing the quantitative discharge structure at the screening and discharge end and counting the starter by counting the starter each time it is screened.

[0004] However, the operation still suffers from drawbacks. Manual feeding can only pour the material into the feed end of the screening device at one time. During vibrating screening, material accumulation not only easily leads to collisions and material falling, but it is also difficult to control the feeding speed of the raw materials. Furthermore, it still relies on manual loading and unloading. Due to the insufficient overall strength of the fermentation agent raw materials, the existing mechanical structure cannot evenly distribute the material, otherwise the fermentation agent is prone to scattering. Therefore, there is an urgent need for a specialized device with anti-falling material, automatic unloading functions, and high screening efficiency. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an automatic screening device for preventing the fermentation agent from falling off. The device stores and feeds the material, which is guided by an inclined plane. The feeding path is divided in sequence, and the inclined plate guides the material back and forth to avoid direct falling and collision. This not only prevents the fermentation agent from falling and scattering, but also disperses the raw material pile, allowing for orderly feeding and improving the screening effect. The open end is closed during the screening process to prevent the raw material from falling off during vibration screening, making it highly practical. The device can quickly switch the receiving position to avoid manual receiving and improve processing efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic screening device for preventing the falling of fermented rice wine starter, including a screening structure and a feeding structure that cooperates with it. The screening structure includes a base frame, which is connected to the screening trough through multiple sets of elastic support members. The screening trough is provided with multiple sets of screen holes, a vibration source and a shielding structure. The discharge end of the screening trough is provided with a discharge cooperation structure and an opening and closing structure. The base frame is provided with a guide trough that cooperates with multiple sets of screen holes. The discharge end of the guide trough is provided with a collection box.

[0007] The feeding structure includes a support frame, a feeding box on the support frame, a feeding chute at one end of the feeding box away from the screening trough, a feeding chute at the other end of the feeding box that cooperates with the feeding end of the screening trough, and multiple sets of material handling plates on the feeding chute.

[0008] In a preferred embodiment, the unloading mechanism includes a fixed seat, which is connected to a turntable via a rotating shaft. The turntable has multiple mating seats and positioning holes. An oil receiving box is placed inside the mating seat. The fixed seat has an adjusting seat, which has a support rod. The support rod has a sliding rotating plate that mates with it, and the sliding rotating plate has a positioning rod that mates with the positioning holes.

Detailed Implementation

[0030] Example 1:

[0031] As shown in Figures 1-8, the automatic screening device for preventing material from falling off the fermented rice wine includes a screening structure 1 and a feeding structure 2 that cooperates with it. The screening structure 1 includes a base frame 4, which is connected to a screening trough 6 through multiple sets of elastic support members 5. The screening trough 6 is provided with multiple sets of screen holes 18, a vibration source 19 and a shielding structure. The discharge end of the screening trough 6 is provided with a discharge cooperation structure 3 and an opening and closing structure. The base frame 4 is provided with a guide trough 7 that cooperates with multiple sets of screen holes 18. The discharge end of the guide trough 7 is provided with a collection box 9.

[0032] The feeding structure 2 includes a support frame 20, a feeding box 21 on the support frame 20, a feeding chute 22 at one end of the feeding box 21 away from the screening trough 6, and a feeding chute 23 at the other end of the feeding box 21 that cooperates with the feeding end of the screening trough 6. Multiple sets of material handling plates 24 are provided on the feeding chute 22.

[0033] In a preferred embodiment, the unloading structure 3 includes a fixed base 27, which is connected to a turntable 29 via a rotating shaft 28. The turntable 29 has multiple mating seats 30 and positioning holes 32. An oil receiving box 31 is placed inside each mating seat 30. An adjusting seat 33 is provided on the fixed base 27, and a support rod 34 is provided on the adjusting seat 33. A sliding rotating plate 35, which mates with the support rod 34, is provided on the sliding rotating plate 35, and a positioning rod 36, which mates with the positioning hole 32, is provided on the sliding rotating plate 35. This enables multi-station cyclic unloading.

[0034] In a preferred embodiment, the shielding structure includes a shielding frame 11 connected to the screening trough 6 via a hinge structure 10. The shielding frame 11 is provided with a flexible surface material 12, and is connected to the screening trough 6 via a connecting locking structure 13. This prevents the raw materials from tipping over during the screening process.

[0035] In a preferred embodiment, the opening and closing structure includes fixed arms 15 symmetrically arranged on the screening trough 6. Each fixed arm 15 has a baffle 16 that rotates with it. The rotation shaft of the baffle 16 is connected to the output end of a servo motor 17 mounted on the fixed arm 15. This controllable opening and closing facilitates dispersed material collection during continuous screening.

[0036] In a preferred embodiment, the feed trough 23 is provided with staggered buffer ramps 25. The staggered buffer ramps 25 form a "Z"-shaped flow channel, reducing the kinetic energy of the material.

[0037] In a preferred embodiment, the discharge end of the feed trough 23 is equipped with a guide arc plate 26. This prevents the raw material from falling directly onto the screen surface of the screening trough 6, reducing impact and minimizing material breakage.

[0038] In a preferred embodiment, the end of the feed plate 24 furthest from the feed trough 23 is a semi-circular head. This reduces material flow resistance and prevents the hard-edged surface from colliding with the raw material fermentation agent, causing it to loosen.

[0039] In a preferred embodiment, the bottom of the base frame 4 is provided with a buffer pad 8 to prevent excessive shaking and noise of the entire device during vibrating screening.

[0040] In a preferred embodiment, the discharge end of the screening tank 6 is provided with a material collection point 14. Material is collected and discharged.

[0041] Example 2:

[0042] As shown in Figures 5 and 6, the inclined angle of the buffer ramp 25 is 45°~60° to ensure a smooth transition of materials.

[0043] As shown in Figure 3, the flexible surface material 12 covers the inner side of the shielding frame 11 and can be disassembled and connected by Velcro or pressure strips for easy cleaning and replacement.

[0044] As shown in Figures 1-4, the elastic support 5 is preferably a polyurethane shock absorber, and the vibration source 19 is an eccentric motor.

[0045] Example 3:

[0046] As shown in Figures 1-8, the working principle of this utility model is as follows:

[0047] The elastic support 5 provides the vibration freedom of the screening trough 6. The vibration source 19 drives the screening trough 6 to vibrate at high frequency and micro amplitude, forcing the material to jump forward on the screen surface. Particles with substandard diameter enter the guide trough 7 through the screen hole 18, and coarse particles move along the screen surface to the discharge end.

[0048] The shielding frame 11 covers the surface opening of the screening tank 6 through the hinge structure 10. The flexible surface material 11 (such as a silicone curtain) absorbs vibration energy and suppresses material splashing. The connecting locking structure 13 (such as a pin) ensures that the shielding frame is stably closed.

[0049] The semi-circular head design of the feed plate 24 reduces the resistance to material flow and avoids the hard corners from colliding with the raw material fermentation agent, causing it to become loose. The staggered buffer inclined plate 25 forms a "Z" shaped flow channel, which reduces the kinetic energy of the material and avoids the impact causing the raw material to become loose in the screening tank 6.

[0050] The servo motor 17 drives the opening and closing of the baffle and coordinates with the manual adjustment and rotation of the turntable 29 to disperse the material in multiple receiving boxes 31, realizing multi-station cyclic unloading.

[0051] The beneficial effects of this utility model are as follows: the material is stored and fed in conjunction with the feed, and the material is fed through the inclined plane. The feeding path is divided in sequence and the inclined plate guides the material back and forth to avoid direct falling and collision. This not only prevents the fermentation agent from falling and scattering, but also disperses the raw material pile, allowing for orderly feeding and improving the screening effect. The closed end of the opening is fitted during the screening process to prevent the raw material from falling during the vibrating screening process, making it highly practical. The material receiving position can be quickly switched to avoid manual material receiving and improve processing efficiency.
