Description

Technical Field

[0001] This utility model relates to the field of soybean meal processing technology, and in particular to a soybean meal crushing device. Background Technology

[0002] Soybeans are highly nutritious; 1 kg of soybeans contains the same amount of protein as 2 kg of beef or 4.5 kg of pork. Soybean meal is a byproduct of soybean oil extraction. Currently, soybean meal is primarily used as animal feed, with approximately 85% used for poultry and pig farming. The various amino acids in soybean meal are well-suited to the nutritional needs of poultry and pigs. Experiments have shown that, without the addition of animal protein, the amino acids in soybean meal alone are sufficient to balance the nutrition of poultry and pigs, thereby promoting nutrient absorption. In poultry and pig farming, soybean meal is utilized to the maximum extent. To enable poultry and pigs to absorb the amino acids and other nutrients in soybean meal more quickly, it is ground into soybean meal powder, and other additives are added to the powder to enhance its nutritional value.

[0003] Existing grinding devices have significant limitations in practical applications, as they only have a single grinding step. This often results in difficulties achieving ideal grinding results when grinding soybean meal. Especially when soybean meal is hard, a single grinding step is insufficient to fully grind it, resulting in soybean meal particles of varying sizes and textures, which greatly affects subsequent processing. To address this technical problem, this application proposes a soybean meal grinding device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soybean meal pulverizing device. The device uses a servo motor to drive two pulverizing rollers to pulverize soybean meal. Qualified pulverized soybean meal is discharged from the pulverizing barrel through a filter screen, while the rotating tilting barrel flips the unqualified soybean meal and brings it above the pulverizing rollers for multiple pulverizations, thereby making the final product more uniform in size.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A soybean meal grinding device includes a grinding barrel, a feeding shell fixedly connected to the top of the grinding barrel, two grinding rollers rotatably connected to the inner wall of the grinding barrel, and a tilting barrel rotatably connected to the inner wall of the grinding barrel. The front side of the inner wall of the tilting barrel is connected to the front side of the two grinding rollers through a transmission assembly to enable the grinding rollers and the tilting barrel to rotate together. A filter screen is slidably connected to the bottom side of the inner wall of the grinding barrel. The outer wall of the tilting barrel abuts against the top side of the filter screen. The front side of the filter screen is connected to the front end of the grinding barrel through a limiting assembly to fix the filter screen.

[0007] Furthermore, the transmission assembly includes a face gear fixedly connected to the front end of the crushing roller, at least eight teeth fixedly connected to the outer wall of the face gear on the left side, a toothed column rotatably connected to the front side of the crushing barrel, the front sides of the two face gears meshing with the outer wall of the toothed column, and a toothed ring fixedly connected to the front side of the inner wall of the tilting barrel.

[0008] Furthermore, a first gear is rotatably connected to the front side of the crushing barrel, and a second gear is fixedly connected to the rear end of the first gear. The outer wall of the second gear meshes with the inner wall of the gear ring, and the eight teeth on the opposite side abut against the outer wall of the first gear.

[0009] Furthermore, a mounting frame is fixedly connected to one side of the crushing barrel, and a servo motor is fixedly connected to the inner wall of the mounting frame.

[0010] Furthermore, the servo motor drive end is fixedly connected to the right end of the gear column.

[0011] Furthermore, the limiting assembly includes two limiting rods fixedly connected to the front side of the filter screen, with limiting blocks inserted into the top of the inner wall of the limiting rods, and limiting push blocks fixedly connected to the top of the two limiting blocks.

[0012] Furthermore, four limiting springs are fixedly connected to the top of the limiting push block, and a fixing block is fixedly connected to the front side of the crushing barrel, with the bottom of the fixing block fixedly connected to the top of the limiting springs.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the servo motor drives two grinding rollers to rotate and grind the soybean meal. The qualified ground soybean meal is discharged from the grinding barrel through the filter screen. At the same time, the rotating drum flips the unqualified soybean meal and brings it to the top of the grinding rollers for multiple grinding, so as to make the final product more uniform in size.

[0015] 2. In this utility model, by pulling the limiting push block upward, the limiting insert block is disengaged from the inner wall of the limiting rod, thus releasing the fixing of the limiting rod. The filter screen can be taken out and replaced by grasping the limiting rod, making the replacement of the filter screen more convenient. After the replacement is completed, the filter screen is inserted back into the crushing barrel, the limiting push block is released, and the limiting spring rebounds to push the limiting push block and the limiting insert block to slide into the limiting rod to fix the filter screen.
