Description

Technical Field

[0001] This invention relates to the field of automatic feeding technology, specifically to an automatic feeding device based on feed production and processing. Background Technology

[0002] Automatic feeding devices are core supporting equipment in the production and processing of agricultural products and feed. They are mainly used to realize the automated feeding, conveying, pre-processing and grading of feed raw materials. They can replace manual labor in completing processes such as raw material handling, breaking up clumps and screening impurities. They have advantages such as high conveying efficiency, strong continuous operation and adaptability to large-scale production. They can effectively reduce labor costs and improve the overall automation level of feed processing. They are an indispensable key equipment in modern feed processing production lines.

[0003] However, existing automatic feeding devices lack efficient and adjustable dispersing structures when raw materials are prone to moisture and clumping, which can easily cause blockages in pipelines and screens. Most screening components have fixed aperture designs, which cannot be flexibly adjusted according to the type of feed and particle size differences, resulting in poor grading and screening effects. The dispersing and screening mechanisms are independent of each other and lack a linkage adjustment mechanism, which cannot adapt to the processing needs of different materials. The design of the waste discharge channel is unreasonable, and waste is easy to accumulate and remain, resulting in high equipment failure rate and insufficient versatility and feeding stability.

[0035] The base 51 has multiple equally spaced sieve holes.

[0040] In one embodiment of the present invention, the second base 61 is installed on the mounting frame 4. The bottom frame 63 and the second base 61 are buffered and shock-absorbing by springs.

[0042] The first abutment block 71 and the second abutment block 72 are set as two sets. The connecting rod 73 is fixedly connected to the two sets of the first abutment blocks 71. A through groove is opened on the surface of the hopper 2. A protrusion is provided at the bottom of the abutment plate 75. The protrusion of the abutment plate 75 slides in the through groove on the surface of the hopper 2.

[0043] The filter box 62 has a through groove. The first abutment block 71 slides in the through groove of the filter box 62, and the second abutment block 72 rotates in the through groove of the filter box 62. The second abutment block 72 is connected to the inner wall of the through groove of the filter box 62 by a spring.

[0044] In one embodiment of the present invention, the electric push rod drives the first abutment block 71 to slide, and pushes the second abutment block 72 to drive the second screen plate 65 to rotate to adjust the discharge hole diameter; at the same time, the angle of the stirring blade 53 is adjusted synchronously through the linkage of the connecting rod 73, the abutment rod 74, and the abutment plate 75, and the matching spring realizes the automatic reset of each component.

[0045] As one embodiment of the present invention, the method includes the following steps:

[0046] S1: Vacuum pump 3 sucks material into hopper 2, rotating drum 52 drives stirring blade 53 to break up clumps of material, connecting shaft 54 ​​slides along spiral groove of rotating drum 52, and adjusts the angle of stirring blade 53 with spring, and the screen hole of base 51 completes the initial filtration of material.

[0047] S2: The material enters the screening box 62 and is screened in two stages by two sets of screen plates 64 and 65. Impurities are discharged from the upper discharge port 66, and qualified materials enter the hopper 2 through the lower discharge port 67. The spring buffers the screening vibration.

[0048] S3: The electric push rod drives the screen plate 2 to rotate 65 to adjust the discharge hole diameter. The angle of the stirring blade 53 is adjusted synchronously through the connecting rod 73, the abutting rod 74, and the abutting plate 75. The spring realizes the automatic reset of the components.

[0049] Working Principle: After the device is started, the vacuum pump 3 at the top of the hopper 2 on the base frame 1 generates a stable negative pressure suction. Under the action of negative pressure, the feed material to be processed is evenly sucked into the hopper 2 and first enters the pre-treatment area where the base 51 is located. The base 51 is fixed to the top of the hopper 2, and the rotating drum 52 at its upper end is driven to rotate by the motor. The rotating drum 52 drives four sets of circumferentially evenly distributed stirring blades 53 to rotate synchronously, which fully crushes and disperses the lumps of feed formed by moisture and compression, and avoids the lumps of material clogging the subsequent screening structure. The protrusions on the surface of the connecting shaft 54 ​​slide along the spiral groove on the inner wall of the rotating drum 52 for limiting. With the spring extension and contraction action between the sleeve 55 and the abutment plate 56, the stirring blades 53 are driven to realize the dynamic adjustment of the working angle, which improves the uniformity and fullness of material dispersion. The multiple sets of evenly spaced screen holes on the base 51 can perform preliminary filtration on the dispersed material, intercepting the oversized impurities in the material, reducing the workload of the subsequent precision screening stage, and ensuring the stable operation of the subsequent process.

[0050] After pretreatment, the material falls evenly into the screening area on the mounting frame 4 inside the silo 2, entering the two-stage grading and screening process. The base 2 61 is fixed in the mounting frame 4, and its upper bottom frame 63 is connected to the base 2 61 by a spring. The spring plays a buffering and shock-absorbing role during the screening process, reducing equipment vibration and improving screening stability. After the material enters the screening frame 62, it passes through two sets of screening discs 1 64 and 2 65 in sequence. The first set of screening discs performs coarse screening of the material. Larger impurities and unqualified large particles are intercepted by screening disc 1 64 and discharged from the equipment through the upper discharge port 66 that penetrates the inner wall of the silo 2. The second set of screening discs performs fine screening of the material. Qualified feed material that meets the production specifications passes smoothly through the drop holes of screening disc 1 64 and screening disc 2 65 and enters the bottom of the silo 2 through the lower discharge port 67, completing the automatic feeding operation and realizing the separation and grading of impurities in the material, effectively ensuring the purity of the feed and the quality of subsequent processing.

[0051] When processing feed materials with different particle sizes and fluffiness, the equipment can synchronously adjust the size of the material discharge holes on the screen discs and the angle of the stirring blades 53. The electric push rod serves as the power source, and its telescopic end drives the first abutment block 71 to slide within the through groove of the screening frame 62. The first abutment block 71 pushes against the second abutment block 72, driving the second screen disc 65, which is fixedly connected to the second abutment block 72, to rotate relative to the first screen disc 64. This changes the overlapping area of ​​the material discharge holes on the two screen discs, precisely adapting to the screening aperture requirements of different materials. Simultaneously, the first abutment block 71 drives the abutment rod through the connecting rod 73. 74 moves synchronously, with the abutting rod 74 pushing against the abutting plate 75. The abutting plate 75 slides along the through groove on the surface of the hopper 2 and acts on the abutting piece 56, simultaneously adjusting the working angle of the stirring blade 53 to ensure that the material dispersion intensity and screening specifications are precisely matched. The springs between the abutting block 72 and the screening frame 62, and between the sleeve 55 and the abutting piece 56, can realize the automatic reset of each moving part, ensuring the stable operation of the crushing, screening, and adjustment cycle. No manual intervention is required throughout the process, greatly improving the efficiency, versatility, and operational stability of automatic feeding in feed production.
