DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, the utility model provides a vegetable oil high-efficiency crushing and grinding device, comprising a grinding box 1, wherein a crushing assembly 8 is arranged inside the grinding box 1, and the crushing assembly 8 comprises a first roller 801 arranged on the inner wall of the grinding box 1 through a rotating shaft;

[0027] A second motor 7 is fixedly disposed at the rear side of the grinding box 1, and an output shaft of the second motor 7 extends into the grinding box 1 and is fixedly connected to the rear end of the first roller 801. A plurality of annular grooves 803 are formed at the outer end of the first roller 801.

[0028] A bracket 805 is provided on one side of the first roller 801, and a second roller 802 is provided on the inner wall of the bracket 805 via a rotating shaft. The outer end of the second roller 802 contacts the outer end of the first roller 801, and the outer end of the second roller 802 is fixed with a plurality of annular protrusions 804 that correspond to the annular grooves 803 one by one and mesh with each other.

[0029] During the working process, the first roller 801 and the second roller 802 are in contact with each other, and under the drive of the second motor 7, the first roller 801 and the second roller 802 rotate synchronously, and the annular grooves 803 and the annular protrusions 804 at the outer ends of the two rollers are also meshed with each other, and the raw materials are placed on the contacting part of the two rollers. While the first roller 801 and the second roller 802 rotate, the raw materials can be squeezed and crushed. Since the annular grooves 803 and the annular protrusions 804 are provided, the contact part of the first roller 801 and the second roller 802 is changed from a straight line to a broken line. Without changing the length of the first roller 801 and the second roller 802, the length of the contact position of the two rollers is extended, and more raw materials can be processed per unit time, thereby improving the efficiency of crushing and grinding.

[0030] In order to provide the force for crushing the raw materials, such as Figure 3 , 4 As shown, two telescopic rods 806 and two springs 807 are fixedly provided on one side of the bracket 805, and one end of the telescopic rods 806 and the springs 807 are fixedly connected to the inner wall of the grinding box 1, and the elastic force of the springs 807 is used to make the first roller 801 and the second roller 802 in close contact;

[0031] Two fixing plates 11 are fixed on the inner wall of the grinding box 1 , and brushes 12 are fixed at the bottom ends of the fixing plates 11 . The brushes 12 at the bottom ends of the two fixing plates 11 are in contact with the outer ends of the first roller 801 and the second roller 802 , respectively.

[0032] During the processing, the spring 807 is in a bent state, so the elastic force of the spring 807 pushes the bracket 805 and the second roller 802, so that the second roller 802 is close to the surface of the first roller 801, thereby providing pressure for rolling. At the same time, during the rotation of the first roller 801 and the second roller 802, the surfaces of the two rollers and the annular groove 803 and the annular protrusion 804 all rub against the brush 12, thereby cleaning the residual raw materials stuck on their surfaces.

[0033] The raw materials after crushing need to be filtered, such as Figure 1 ,3 As shown in Figure 5, an inclined filter screen plate 9 is fixedly provided on the inner wall of the grinding box 1, and the crushed raw materials are filtered by the filter screen plate 9. The filter screen plate 9 is located at the bottom of the grinding assembly 8. A storage box 10 is provided at the bottom end of the grinding box 1. The qualified raw materials after crushing fall into the storage box 10. The storage box 10 is located at the bottom of the filter screen plate 9. The front side of the grinding box 1 is provided with a box door through a hinge.

[0034] A recovery box 2 is fixedly provided on one side of the grinding box 1, and a recovery channel 13 connected to the grinding box 1 is fixedly provided on the side of the recovery box 2 facing the grinding box 1. The recovery channel 13 is located at the lowest end of the filter screen plate 9, and the raw materials that are not fully ground enter the recovery box 2 through the recovery channel 13;

[0035] A maintenance panel 4 is provided on a side of the recovery box 2 away from the grinding box 1 through a hinge, and a circulation component 3 is provided on the top of the recovery box 2 .

[0036] The raw materials crushed at the crushing assembly 8 fall downward on the top of the filter screen plate 9. The qualified raw materials that have been fully crushed pass through the filter screen plate 9 and fall into the storage box 10 for storage. The raw materials that have not been fully crushed roll downward along the filter screen plate 9 and finally roll into the recovery box 2 through the recovery channel 13.

[0037] Raw materials that cannot be completely crushed need secondary processing, such as Figure 1 , 3 As shown in , 5, the circulation component 3 includes a conveying pipe 301 fixedly arranged at the top of the recycling box 2, the bottom end of the conveying pipe 301 extends to the inside of the recycling box 2, and a conveying shaft 302 is arranged inside the conveying pipe 301, and the bottom end of the conveying shaft 302 extends to the inside of the recycling box 2 and is movably connected to the bottom end of the inside of the recycling box 2 through a bearing;

[0038] A first motor 303 is fixedly provided at the top of the conveying pipe 301, and the top of the conveying shaft 302 extends to the top of the conveying pipe 301 and is fixedly connected to the output shaft of the first motor 303. The conveying shaft 302 rotates to convey the insufficiently crushed raw materials upward for further processing, and a connecting hose 304 is fixedly provided at the outer end of the conveying pipe 301.

[0039] The grinding box 1 has a removable top plate 5 at the top, and a feeding box 6 is fixedly provided at the top of the top plate 5. The bottom end of the feeding box 6 extends into the grinding box 1 and has a strip groove, which is located directly above the contact portion between the first roller 801 and the second roller 802. One end of the connecting hose 304 is fixedly connected to the feeding box 6.

[0040] The raw materials enter the recycling box 2 and accumulate. After accumulating to a certain level, the first motor 303 is turned on, and the conveying shaft 302 is driven to rotate by the first motor 303. After rotation, the raw materials accumulated in the recycling box 2 are conveyed upward along the conveying pipe 301 and finally conveyed to the feeding box 6 through the connecting hose 304, and then fall down from the bar groove at the bottom of the feeding box 6 to the crushing assembly 8 for processing, and this cycle is repeated. The unprocessed raw materials are also put into the feeding box 6 and enter the grinding box 1 from the bar groove to be processed.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
