Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to an automatic nut grinding device. Background Art

[0002] Nuts are a type of closed fruit with a hard skin and one or more seeds inside, such as almonds, peanuts, etc.

[0003] In the fine processing of nuts, the nuts need to be crushed before processing. Since some products have high requirements on the degree of crushing of nuts, the crushed nuts need to be ground more finely before subsequent ingredient processing. When grinding nuts, the existing nut grinding devices usually pour the crushed nuts directly into a pair of grinding rollers for grinding. If the amount of nut crushed nuts is not controlled well and leads to excessive amount, the grinding efficiency of the grinding rollers will be affected, thereby reducing the product quality.

[0004] Therefore, a nut automatic grinding device is proposed to solve the above problems. Utility Model Content

If the amount of nut crushed input is not controlled well, resulting in excessive amount, it will affect the grinding efficiency of the grinding rollers, thereby reducing the product quality.

[0010] Furthermore, a guide trough which is connected to the left end of the separation chamber and is used for guiding out unqualified nuts is fixed at the left end of the shell.

[0011] Furthermore, a lower hopper with openings at the top and bottom is fixed to the bottom of the shell.

[0012] Furthermore, a driving mechanism is also provided on the shell, which can be used to drive the feeding mechanism, the grinding mechanism and the separation mechanism to operate together.

[0013] Furthermore, the driving mechanism includes a driving motor fixed on the frame, and the rotating shafts in the two grinding rollers, the feeding rotating shaft and the separation rotating shaft all pass through the right side of the shell. The output shaft of the driving motor is connected to the rotating shaft in one of the grinding rollers through a belt transmission structure, and the rotating shafts in the two grinding rollers are connected to the feeding rotating shaft and the separation rotating shaft through a chain transmission structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, an automatic nut grinding device includes a shell 1 fixed on a frame, the shell 1 includes a loading chamber 11, a grinding chamber 12 connected to the bottom of the loading chamber 11, and a separation chamber 13 connected to the bottom of the grinding chamber 12.

[0023] A feeding mechanism 2 is provided in the feeding chamber 11 of the housing 1. The top of the feeding chamber 11 is open. Nuts are poured into the feeding chamber 11 from the top opening of the feeding chamber 11. The feeding mechanism 2 can slowly push the materials from the outlet of the feeding chamber 11 into the grinding chamber 12. Figure 1-2 As shown, the feeding mechanism 2 includes a feeding rotating shaft 21 rotatably arranged in the shell 1 through a bearing, and a feeding screw 22 and a stirring blade 23 located above the outlet of the feeding chamber 11 are fixed to the outside of the feeding rotating shaft 21.

Figure 2 As shown, a pair of grinding rollers 31 that can rotate in opposite directions are provided in the grinding mechanism 3 through the rotation of a rotating shaft. When nuts fall into the grinding chamber 12, they can be fully ground by the two grinding rollers 31 that rotate in opposite directions. The ground nut powder falls into the separation chamber 13 from the outlet of the grinding chamber 12.

[0025] The separation chamber 13 of the housing 1 is provided with a separation mechanism 4 for separating fully ground nut powder from incompletely ground nut powder. The incompletely ground nut powder can be led out, collected and re-added to the feeding chamber 11 for re-grinding. Figure 2-3 As shown, the separation mechanism 4 includes a separation rotating shaft 41 which is rotatably arranged in the shell 1 and located in the separation chamber 13 through a bearing, a separation spiral blade 42 is fixed to the outside of the separation rotating shaft 41, a plurality of leakage holes 43 which are evenly and equidistantly distributed are opened at the bottom of the shell 1, and a guide groove 44 which is connected to the left end of the separation chamber 13 and is used for guiding unqualified nuts is fixed at the left end of the shell 1.

[0026] The nut powder ground by the grinding roller 31 falls into the separation chamber 13, the separation rotating shaft 41 rotates, and the separation spiral blade 42 transports the nut powder to the left. The nut powder that is fully ground to meet the requirements leaks out through the leakage hole 43 for collection, and the nut powder that does not meet the requirements after grinding is transported to the guide trough 44 through the separation spiral blade 42 and is discharged from the guide trough 44.

[0027] A lower hopper 45 with openings at the top and bottom is fixed to the bottom of the shell 1 , and the nut powder leaking out of the leakage hole 43 is discharged through the lower hopper 45 , which is more convenient for collection.

[0028] In addition, the housing 1 is also provided with a driving mechanism 5, which can be used to drive the feeding mechanism 2, the grinding mechanism 3 and the separation mechanism 4 to operate together. Figure 1-2 As shown, the driving mechanism 5 includes a driving motor 51 fixed on the frame, the rotating shafts in the two grinding rollers 31, the feeding rotating shaft 21 and the separating rotating shaft 41 all pass through the right side of the shell 1, and the output shaft of the driving motor 51 is connected to the rotating shaft in one of the grinding rollers 31 through a belt transmission structure 52, and the rotating shafts in the two grinding rollers 31 are connected to the feeding rotating shaft 21 and the separating rotating shaft 41 through a chain transmission structure 53, and the sprocket outside the rotating shaft in one of the grinding rollers 31 is located on the inner side of the chain in the chain transmission structure 53, and the sprocket outside the rotating shaft in the other grinding roller 31 is located on the outer side of the chain in the chain transmission structure 53, so that a pair of grinding rollers 31 can rotate in opposite directions.

[0029] The belt transmission structure 52 and the chain transmission structure 53 are both conventional transmission methods known to the public in the prior art, and their specific structures and principles are not described in detail here.

[0031] By adopting the above-mentioned automatic nut grinding device, the feeding frequency of nuts can be controlled, and the nut powder that does not meet the requirements can be separated to facilitate re-grinding. The specific grinding method is as follows:

[0032] The nuts are poured into the loading chamber 11 from the top opening of the loading chamber 11, and the loading screw propeller 22 drives the nuts to be transported to the top of the loading chamber 11 outlet by driving the loading rotating shaft 21 to rotate. The nuts are then evenly stirred by the stirring blade 23 and fall into the grinding chamber 12, where they can be fully ground by the two grinding rollers 31 rotating in opposite directions. The ground nut powder falls into the separation chamber 13 from the outlet of the grinding chamber 12, and the separation rotating shaft 41 rotates, and the separation spiral blade 42 transports the nut powder to the left. The nut powder that is fully ground and meets the requirements leaks out through the leakage hole 43 and is discharged from the lower hopper 45 for collection, while the nut powder that does not meet the requirements after grinding is transported to the guide trough 44 through the separation spiral blade 42 and is discharged from the guide trough 44.
