Description
Technical Field
[0001] The utility model relates to the technical field of hard food detection, in particular to a crushing device for hard food detection. Background Art
[0002] Common hard foods include nuts (such as almonds, walnuts, hazelnuts, etc.), certain grains (such as wheat kernels, corn kernels), hard candies (such as fruit candies), etc. These foods are relatively difficult to chew and break, and have obvious differences in texture characteristics from soft and easily deformed foods. In order to ensure food safety, hard foods usually need to be tested.
[0003] Existing nut foods require a crushing device to remove the hard shell on the surface before testing the quality of the flesh inside. The crushing devices on the market mainly consist of two crushing rollers that remove the nut shells through rotation and squeezing. However, the spacing between the crushing rollers is fixed. Nuts with large volume differences such as walnuts and almonds require different types of crushing devices for shelling. This is not only inconvenient but also increases the cost of food testing. Therefore, to address the above problems, we propose a new type of crushing device for hard food testing. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1, as Figure 1-Figure 5The cam 52 is connected to the outer surface of the two sliding seats 51, and the outer surface of the two sliding seats 51 is connected to the outer surface of the two sliding seats 51. A group of mounting seats 6 are fixedly connected near the edge on the outer surfaces of both sides, and the outer surfaces of the two groups of mounting seats 6 are rotatably connected to the rotating shaft 62. A motor 61 is installed on the rear surface of one of the mounting seats 6, and the output end of the motor 61 passes through the rear surface of the mounting seat 6 and is fixedly connected to the rear end of one of the rotating shafts 62. Both ends of the other crushing shaft 4 are fixedly connected to the fourth bevel gear 71, and the outer surface of the fourth bevel gear 71 is meshed with the third bevel gear 7. The third bevel gear 7 is fixedly connected to the outer surface of the rotating shaft 62 near the front side, and the second bevel gear 63 is slidably connected to the outer surface of the rotating shaft 62 near the middle position. A limiting tooth 65 is provided on the outer surface of the rotating shaft 62 near the middle position, and a limiting groove 64 is provided on the inner wall of the second bevel gear 63. The limiting tooth 65 and the limiting groove 64 are slidingly connected. The top of the crushing box 1 is fixedly connected to the feed hopper 11, the bottom of the crushing box 1 is fixedly connected to the transfer box 2, the bottom of the transfer box 2 is fixedly connected to the lower hopper 22, and the bottom of the transfer box 2 is fixedly connected to the support frame 3 near the edge.
[0025] The effect achieved by the entire embodiment 1 is that when the quality of the flesh of hard foods such as nuts is to be tested, the food sample can be put into the large feed hopper 11, and the hard nuts will fall between the two sets of crushing wheels 41. Then the motor 61 is started to drive the rotating shaft 62 to rotate. At this time, the second bevel gear 63 and the third bevel gear 7 on the surface of the rotating shaft 62 will follow the rotation and drive the first bevel gear 53 and the fourth bevel gear 71 to rotate in the opposite direction, thereby cooperating with the two crushing shafts 4 to drive the two sets of crushing wheels 41 to rotate in the opposite direction to crush the shells of the hard nuts and then perform food testing. In addition, when using this device to crush the shells of hard nuts of different sizes, By starting the electric push rods 5 in the two slide grooves 14 to drive the slide 51 to move, one of the crushing shafts 4 can be driven to move, and when the slide 51 moves, it will drive the second bevel gear 63 to move through the L-shaped bracket 52, and the second bevel gear 63 and the rotating shaft 62 can slide linearly on the surface of the rotating shaft 62 while rotating with the cooperation of the limiting groove 64 and the limiting tooth 65, thereby achieving the effect of adjusting the distance between the two sets of crushing wheels 41. This design does not require changing the device to crush hard nut foods of different sizes, which is not only convenient to operate, but also reduces the cost of food testing. The support frame 3 is mainly used to support the device off the ground.
[0026] Example 2, as Figure 1-Figure 5 As shown, a slide groove 14 is provided on the rear surface of the transfer box 2, a discharge port 21 is provided on the front surface of the transfer box 2, and the inner walls on both sides of the transfer box 2 are fixedly connected with slide rails 13. A sieve plate 42 is placed between the tops of the two slide rails 13, and the outer surface of the sieve plate 42 is slidably fitted with the inner wall of the slot 12. The sieve plate 42 is inclined and the top and the inner bottom of the discharge port 21 are on the same straight line.
[0027] The effect achieved by the entire embodiment 2 is that when the crushed hard nut shell meat is separated, it will fall onto the sieve plate 42 inside the transfer box 2, and then the smaller broken shells or pulp will fall into the lower hopper 22 through the sieve plate 42 and be discharged, and the remaining part will slide downward to the discharge port 21 and be discharged, thereby avoiding the problem of increased subsequent workload caused by the mixing of a large amount of broken shells and pulp, further improving the convenience of use, and, according to different types of nuts, the sieve plate 42 can be pulled out of the slot 12 for replacement and then reinserted, and the slide rail 13 is mainly used to limit the sieve plate 42.
[0028] Working principle: When testing the quality of the flesh of hard foods such as nuts, the food samples can be put into the large feed hopper 11. At this time, the hard nuts will fall between the two sets of crushing wheels 41. Then the motor 61 is started to drive the rotating shaft 62 to rotate. At this time, the second bevel gear 63 and the third bevel gear 7 on the surface of the rotating shaft 62 will follow the rotation and drive the first bevel gear 53 and the fourth bevel gear 71 to rotate in the opposite direction, thereby cooperating with the two crushing shafts 4 to drive the two sets of crushing wheels 41 to rotate in the opposite direction to crush the shells of the hard nuts and then perform food testing. In addition, when using this device to crush the shells of hard nuts of different sizes, one of the crushing shafts 4 can be driven to move by starting the electric push rods 5 in the two slides 14 to drive the slide 51 to move, and when the slide 51 moves, it will pass through the L-shaped bracket 52 The second bevel gear 63 is driven to move, and the second bevel gear 63 and the rotating shaft 62 can slide linearly on the surface of the rotating shaft 62 and can also rotate with the rotating shaft 62 under the cooperation of the limiting groove 64 and the limiting tooth 65, thereby achieving the effect of adjusting the distance between the two sets of crushing wheels 41. This design does not require replacement of the device to crush hard nut foods of different sizes. It is not only convenient to operate, but also reduces the cost of food testing. When the crushed hard nut shells and meat are separated, they will fall onto the sieve plate 42 inside the transfer box 2, and then the smaller broken shells or pulp will fall through the sieve plate 42 into the lower hopper 22 for discharge, and the remaining part will slide downward to the discharge port 21 for discharge, thereby avoiding the problem of increased subsequent workload caused by the mixing of a large amount of broken shells and pulp, and further improving the convenience of use.
