Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to an eggshell crushing device. Background Technology

[0002] Egg liquid is needed in food production, such as in egg rolls, cakes, and bread rolls. In the streamlined, mass production of factories, the demand for egg liquid is enormous, necessitating industrial equipment. Egg washing machines include processes such as washing, inspection, and cracking. After cracking the eggs, the egg liquid is extracted and stored. The eggshells separate and fall into a collection box. If the eggshells are not crushed or compressed, they occupy a large space and quickly fill the collection box. Currently, egg processing requires a worker to use a pressure bar with a pressure plate attached to the bottom to crush the eggshells. This method requires a worker, increases production costs, and has low crushing efficiency. Therefore, there is an urgent need for an eggshell crushing device to solve these problems.

[0026] Reference Figure 1 An eggshell crushing device includes a frame 100, a crushing frame 200, a crushing roller assembly 300, a drive device 400, and a material holding frame 500.

[0027] The frame 100 is provided with a material holding space 110 with a side opening;

[0028] The crushing frame 200 is mounted on the frame 100 and located above the material holding space 110. The crushing frame 200 is provided with a crushing trough 210 that runs vertically through the machine.

[0029] The crushing roller assembly 300 is rotatably mounted in the crushing trough 210 to receive and crush the eggshells from the previous process.

[0030] The drive unit 400 is mounted on the crushing frame 200 and connected to the crushing roller assembly 300, and is used to drive the crushing roller assembly 300 to rotate;

[0031] The material holding frame 500 is set within the material holding space 110 and can be pulled out through the side opening.

[0032] In this invention, the eggshell crushing device is connected to the end of an egg washing machine, and can process the eggshells output by the egg washing machine. Specifically, the eggshells fall from above the crushing trough 210 onto the crushing roller assembly 300. The driving device 400 drives the crushing roller assembly 300 to rotate, thereby squeezing and crushing the eggshells. The crushed eggshells fall from below the crushing trough 210 into the material collection frame 500. Furthermore, the upper end of the material collection space 110 is connected to the side end of the crushing frame 200, allowing workers to agitate the eggshells in the material collection frame 500 through this connection, so that the crushed eggshells are evenly spread in the material collection frame 500, making full use of the space in the material collection frame 500. It should be noted that it takes about 1 hour for the crushed eggshells to fill the holding frame 500. Workers only need to replace the holding frame 500 every 1 hour. In a further embodiment, the holding space 110 is provided with two lateral openings arranged opposite each other. The first lateral opening is used for discharging material, and the second lateral opening is used for feeding material. That is, when the first holding frame 500 is full of eggshells, the first holding frame 500 can be pulled out part of the first lateral opening, and then the second holding frame 500 can be inserted from the second lateral opening until the second holding frame 500 can bear the crushed eggshells. At this time, the first holding frame 500 can be completely pulled out to achieve uninterrupted eggshell receiving.

[0033] Reference Figure 1 In some embodiments, the crushing roller assembly 300 includes a first crushing roller 310, a second crushing roller 320 and a third crushing roller 330, and the driving device 400 includes a first driving assembly 410 and a second driving assembly 420.

[0034] The first crushing roller 310 and the second crushing roller 320 are arranged on both sides above the third crushing roller 330;

[0035] The first drive assembly 410 is connected to the first crushing roller 310 and the second crushing roller 320, and is used to drive the first crushing roller 310 and the second crushing roller 320 to rotate.

[0036] The second drive assembly 420 is connected to the third crushing roller 330 and is used to drive the third crushing roller 330 to rotate.

[0037] Specifically, the first drive assembly 410 drives the first crushing roller 310 and the second crushing roller 320 to rotate, and the second drive assembly 420 drives the third crushing roller 330 to rotate. The rotation direction of the third crushing roller 330 is opposite to that of the first crushing roller 310 and the second crushing roller 320, thereby squeezing the eggshell in the gap between the three rollers and breaking the eggshell. In a further embodiment, at least two of the first crushing roller 310, the second crushing roller 320 and the third crushing roller 330 are set as rubber rollers. Rubber rollers can improve the friction effect and prevent the eggshell from slipping between the crushing rollers and failing to break.

[0038] Reference Figure 1 In some embodiments, the first drive assembly 410 includes a first motor 411, a drive shaft 412, a first transmission gear set 413, and a second transmission gear set 414. The drive shaft 412 is rotatably mounted on the crushing frame 200 and connected to the output end of the first motor 411. The first transmission gear set 413 is connected between the first crushing roller 310 and the drive shaft 412, and the second transmission gear set 414 is connected between the second crushing roller 320 and the drive shaft 412. Specifically, the first transmission gear set 413 includes a first transmission gear fixedly mounted on the drive shaft 412. The first transmission gear set 414 includes a second transmission gear fixedly mounted on the first crushing roller 310, and a third transmission gear fixedly mounted on the drive shaft 412 and a fourth transmission gear fixedly mounted on the second crushing roller 320. The third transmission gear and the fourth transmission gear mesh with each other. The first motor 411 drives the drive shaft 412 to rotate, and the first transmission gear and the third transmission gear rotate synchronously with the drive shaft 412. The second transmission gear and the fourth transmission gear then drive the first crushing roller 310 and the second crushing roller 320 to rotate respectively.

[0039] Reference Figure 1 In some embodiments, the second drive assembly 420 includes a second motor 421, a drive plate 422, a first transmission rod 423, and a second transmission rod 424. The drive plate 422 is connected to the output end of the second motor 421. One end of the first transmission rod 423 is eccentrically pivoted onto the drive plate 422. One end of the second transmission rod 424 is rotatably connected to the other end of the first transmission rod 423. The other end of the second transmission rod 424 is fixedly connected to the third crushing roller 330. Specifically, the second motor 421 drives the drive plate 422 to rotate. Since one end of the first transmission rod 423 is eccentrically pivoted onto the drive plate 422, the first transmission rod 423 will oscillate back and forth, which in turn drives the second transmission rod 424 to rotate, ultimately realizing the rotation of the third crushing roller 330.

[0040] Reference Figure 1In some embodiments, the frame 100 is provided with a discharge slide plate 600 located at a lateral opening, which provides a smooth transition when the material container 500 is pulled out of the material container space 110.

[0041] Reference Figure 1 In some embodiments, the material holding frame 500 is provided with a handle, which makes it easy to pull the material holding frame 500 out of the material holding space 110.

[0042] The advantages of this invention are: the structure described above can improve the breakability of eggshells, reduce the space occupied by eggshells, eliminate the need for manual intervention, greatly reduce production costs, and has excellent practicality.

[0043] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
