Description

Technical Field

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

[0002] Rice bran can be pressed to extract oil, called rice bran oil, which is rich in nutrients. The remaining product is called rice bran meal, a byproduct of rice bran oil production using the extrusion extraction method. Rice bran meal is a high-quality feed ingredient. Processing rice bran meal requires grinding equipment to facilitate its subsequent use. However, general grinding devices have some drawbacks, such as:

[0003] When rice bran meal contains impurities such as stones, the internal parts of the equipment are easily damaged by impacts with the stones during crushing. At the same time, the stones can also easily jam the equipment, preventing it from operating and thus hindering its use. Utility Model Content

[0004] The purpose of this invention is to provide a rice bran meal crushing and screening device to solve the problems mentioned in the background art.

[0005] A rice bran meal crushing and screening device includes a processing barrel and a fixed cover: the upper end of the processing barrel is provided with a fixed cover, the processing barrel and the fixed cover are fixed together by bolts, a feeding hopper is provided on the upper side of the fixed cover, a crushing mechanism is provided at the center of the fixed cover, and a screening mechanism is provided inside the processing barrel.

[0006] When the device is in use, materials are added into the equipment through the feed hopper, and the fixed cover can be separated from the processing barrel by removing the bolts inside the fixed cover, so as to perform operations such as cleaning the inside of the processing barrel.

[0007] Preferably, the crushing mechanism includes a motor, an output shaft, and a crushing roller. The upper end of the fixed cover is provided with a motor, the lower end of the motor is provided with an output shaft, and the crushing roller is connected inside the output shaft.

[0008] When the device is in use, the output shaft is driven to rotate by the motor. The output shaft and the crushing roller can only slide up and down and cannot rotate. Therefore, when the output shaft rotates, it will drive the crushing roller to rotate, thereby grinding the material.

[0009] Preferably, a crushing roller is slidably disposed inside the output shaft, a supporting spring is disposed inside the output shaft, the upper end of the crushing roller is arc-shaped, and the lower end of the crushing roller is conical.

[0010] When the crushing roller is subjected to a large force, it will move upward under the force of impurities such as stones that cannot be crushed. After the stones are discharged, the support spring will drive the crushing roller to move downward, thus enabling the equipment to carry out the grinding and crushing process.

[0011] Preferably, the interior of the processing barrel is provided with a funnel-shaped grinding plate, and the distance between the lower end of the crushing roller and the grinding plate gradually decreases from top to bottom.

[0012] As the distance between the lower end of the crushing roller and the grinding plate gradually decreases, the grinding of the material becomes more and more thorough, thereby improving the grinding effect of the equipment.

[0013] Preferably, the lower end of the grinding plate has uniformly distributed filter holes, with the filter holes having a smaller diameter at the end closer to the crushing roller and a larger diameter at the other end.

[0014] At the end of the grinding process, the material is screened out through the filter holes, thus preventing material accumulation and increasing the efficiency of grinding and crushing.

[0015] Preferably, the lower end of the grinding plate is provided with support plates at equal intervals, the center of the support plates is penetrated by a connecting shaft, the upper end of the connecting shaft is connected to a crushing roller, and the lower end of the connecting shaft is provided with cleaning brushes at equal angles.

[0016] The support plate supports the grinding plate and the connecting shaft, thereby increasing the stability of the device during use.

[0017] Preferably, the screening mechanism includes a cleaning brush and a filter screen, the filter screen is installed inside the processing barrel, the cleaning brush and the filter screen are in contact, a slag discharge port is opened on the side of the processing barrel, and a material discharge port is opened at the bottom of the processing barrel.

[0018] When the crushing roller rotates, it drives the connecting shaft and the cleaning brush to rotate as well. The crushed material will fall onto the surface of the filter screen under the action of gravity. As the cleaning brush rotates, it moves the material. Since the cleaning brush is arc-shaped, large particles of material cannot be filtered by the filter screen and will be discharged through the slag discharge port on the side, while small particles of material will be filtered by the filter screen and discharged from the discharge port.

[0019] The beneficial effects of this utility model are:

[0020] 1. When the device is in use, the crushing roller grinds and crushes the material. During the crushing process, when the crushing roller encounters large particles such as stones, the crushing roller will move upward under the action of its reaction force, thereby avoiding the equipment from getting stuck or damaged and increasing the service life of the equipment.

[0021] 2. As the gap between the crushing roller and the grinding plate gradually narrows, the grinding effect of the equipment can be improved. Then, the crushed material is quickly discharged through the filter hole. Finally, the material is filtered through the filter screen. The crushed material is discharged through the discharge port at the bottom, while large particles flow out from the slag discharge port as the cleaning brush moves. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In practical implementation: such as Figure 1-4 As shown, a rice bran meal crushing and screening device includes a processing barrel 1 and a fixed cover 2: the upper end of the processing barrel 1 is provided with a fixed cover 2, the processing barrel 1 and the fixed cover 2 are fixed together by bolts, the upper side of the fixed cover 2 is provided with a feed hopper 3, the center of the fixed cover 2 is provided with a crushing mechanism, and the inside of the processing barrel 1 is provided with a screening mechanism.

[0030] When the device is in use, materials are added into the equipment through the feed hopper 3, and the fixed cover 2 can be separated from the processing barrel 1 by removing the bolts inside the fixed cover 2, so as to clean the inside of the processing barrel 1.

[0031] The crushing mechanism includes a motor 4, an output shaft 5, and a crushing roller 7. The upper end of the fixed cover 2 is equipped with the motor 4, the lower end of the motor 4 is equipped with the output shaft 5, and the crushing roller 7 is connected inside the output shaft 5.

[0032] When the device is in use, the output shaft 5 is driven to rotate by the motor 4. The output shaft 5 and the crushing roller 7 can only slide up and down and cannot rotate. Therefore, when the output shaft 5 rotates, it will drive the crushing roller 7 to rotate, thereby grinding the material.

[0033] A crushing roller 7 is slidably installed inside the output shaft 5, and a support spring 6 is installed inside the output shaft 5. The upper end of the crushing roller 7 is arc-shaped, and the lower end of the crushing roller 7 is conical.

[0034] When the crushing roller 7 is subjected to a large force, it will move upward under the force of impurities such as stones that cannot be crushed. After the stones are discharged, the support spring 6 drives the crushing roller 7 to move downward, thereby enabling the equipment to carry out the grinding and crushing process.

[0035] The processing barrel 1 is equipped with a funnel-shaped grinding plate 8 inside, and the distance between the lower end of the crushing roller 7 and the grinding plate 8 gradually decreases from top to bottom.

[0036] As the distance between the lower end of the crushing roller 7 and the grinding plate 8 gradually decreases, the grinding of the material becomes more and more thorough, thereby improving the grinding effect of the equipment.

[0037] The lower end of the grinding plate 8 has uniformly distributed filter holes 9. The filter holes 9 have a smaller diameter at the end closer to the crushing roller 7 and a larger diameter at the other end.

[0038] At the end of the grinding process, the material is screened out through the filter hole 9, thus avoiding the accumulation of material and increasing the efficiency of grinding and crushing.

[0039] A support plate 10 is provided at equal intervals at the lower end of the grinding plate 8. A connecting shaft 11 passes through the center of the support plate 10. A crushing roller 7 is connected to the upper end of the connecting shaft 11. A cleaning brush 12 is provided at equal angles at the lower end of the connecting shaft 11.

[0040] The support plate 10 supports the grinding plate 8 and the connecting shaft 11, thereby increasing the stability of the device during use.

[0041] The screening mechanism includes a cleaning brush 12 and a filter screen 13. The filter screen 13 is installed inside the processing barrel 1. The cleaning brush 12 and the filter screen 13 are in contact. A slag discharge port 14 is opened on the side of the processing barrel 1, and a material discharge port is opened at the bottom of the processing barrel 1.

[0042] When the crushing roller 7 rotates, it drives the connecting shaft 11 and the cleaning brush 12 to rotate. The crushed material will fall onto the surface of the filter screen 13 under the action of gravity. As the cleaning brush 12 rotates, it drives the material to move. Since the cleaning brush 12 is arc-shaped, as the cleaning brush 12 rotates, large particles of material cannot be filtered by the filter screen 13 and will be discharged through the slag discharge port 14 on the side, while small particles of material will be filtered by the filter screen 13 and then discharged from the discharge port.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
