[0030] When the nut food is ground and processed, the nut food is added from the feed hopper 103 to the inside of the crushing cavity 101. Because the plurality of arc-shaped cutter heads 202 on the motor shaft a 201 and the plurality of fixed cutter heads 203 on one side of the inner wall of the crushing cavity 101 are staggered, the nut food will fall into the gap between the plurality of arc-shaped cutter heads 202 and the plurality of fixed cutter heads 203. At this time, the crushing motor 2 is started to work, the crushing motor 2 drives the motor shaft a 201 to rotate at high speed, and the plurality of arc-shaped cutter heads 202 cooperate with the plurality of fixed cutter heads 203 to crush the nut food, so as to facilitate the pretreatment of the nut food of different sizes into the same size of crushed material, make the food crushed material and the grinding gap fit each other, avoid the accumulation of the nut food in the grinding gap, and ensure that the nut food can enter the grinding gap for grinding treatment.
[0031] Wherein, the two sides of the outer end of the grinder 1 are installed with fixed heads 204, the inside of each fixed head 204 is installed with a bearing 205, the two ends of the motor shaft a 201 are respectively connected with the bearings 205 inside the two fixed heads 204, and the two ends of the motor shaft a 201 penetrate inside the fixed heads 204 and are connected with the bearings 205 inside the fixed heads 204 when the motor shaft a 201 is used inside the crushing cavity 101, so as to ensure that the motor shaft a 201 can be stably placed and normally rotated.
[0032] The sieve tray 206 is provided with a plurality of sieve holes 207 with the same size, and the broken materials in the crushing cavity 101 will first fall into the sieve tray 206 and then fall into the grinding cavity 102. The sieve holes 207 on the sieve tray 206 are all provided with the same size, and only the broken materials with the size consistent with the size of the sieve holes 207 can fall into the grinding cavity 102, so that the broken materials are screened to ensure that the size of the broken materials is consistent with the grinding gap.
[0033] The grinding cavity 102 is provided with arc-shaped guide blocks 3 on both sides, and the bottom of each guide block 3 is provided with a grinding roller a4. One side of the grinding roller a4 is provided with a grinding roller b401. The gap between the guide blocks 3, the grinding roller a4 and the grinding roller b401 is opposite. The grinding machine 1 is provided with a reversible motor 402 at the outer end. The output end of the reversible motor 402 is provided with a motor shaft b403. The motor shaft b403 penetrates the grinding cavity 102 and is connected with the grinding roller a4.

[0034] When the broken materials fall into the grinding cavity 102 from the sieve tray 206, the broken materials can be introduced into the gap between the grinding roller a4 and the grinding roller b401 through the guide blocks 3. The reversible motor 402 is started to work. The reversible motor 402 drives the motor shaft b403 to reverse, so that the motor shaft b403 drives the drive gear 404 and the grinding roller a4 to reverse. Since the drive gear 404 is meshed with the transmission gear 406, the drive gear 404 can drive the transmission gear 406 and the rotating shaft 405 to rotate together, so that the rotating shaft 405 drives the grinding roller b401 and the grinding roller a4 to reverse.

[0037] Working principle:
[0038] When the nut food is ground and processed, the nut food is added from the feed hopper 103 to the crushing cavity 101. Since the multiple arc-shaped cutter heads 202 on the motor shaft a 201 and the multiple fixed cutter heads 203 on one side of the inner wall of the crushing cavity 101 are arranged in an interlaced manner, the nut food will fall into the gap between the multiple arc-shaped cutter heads 202 and the multiple fixed cutter heads 203. At this time, the crushing motor 2 is started to work, the crushing motor 2 drives the motor shaft a 201 to rotate at high speed, and the multiple arc-shaped cutter heads 202 cooperate with the multiple fixed cutter heads 203 to crush the nut food, so as to conveniently pretreat the nut food of different sizes into fragments of consistent size, make the food fragments and the grinding gap mutually fit, and avoid the accumulation of nut food in the grinding gap, so as to ensure that the nut food can enter the grinding gap for grinding treatment.
[0039] During the crushing process of the nut food in the crushing cavity 101, the crushed fragments will first fall into the screening support 206 and then fall into the grinding cavity 102. The screen holes 207 on the screening support 206 are uniformly sized, and only the fragments with a size consistent with the screen holes 207 can be discharged and fall into the grinding cavity 102. The crushed fragments are screened to ensure that the size of the fragments is consistent and can mutually fit the grinding gap.
[0040] When the crushed nut food is screened from the screening support 206 and falls into the grinding cavity 102, the fragments can be introduced into the gap between the grinding roller a 4 and the grinding roller b 401 through the guide block 3. The forward and reverse motor 402 is started to work, the forward and reverse motor 402 drives the motor shaft b 403 to reverse, so that the motor shaft b 403 drives the driving gear 404 and the grinding roller a 4 to reverse. Since the driving gear 404 is meshed and connected with the transmission gear 406, the driving gear 404 can drive the transmission gear 406 and the rotating shaft 405 to rotate together, so that the rotating shaft 405 drives the grinding roller b 401 and the grinding roller a 4 to reverse, and then the fragments entering between the grinding roller a 4 and the grinding roller b 401 can be ground. The reverse rolling and extrusion of the grinding roller a 4 and the grinding roller b 401 have sufficient power and a large contact area with the fragments, so that the nut food can be quickly ground, and the working efficiency of food grinding is improved.
