DETAILED DESCRIPTION

[0033] In order to make the technical solutions of the embodiments of the present application clearer, the drawings of the embodiments of the present application will be briefly introduced as follows. Obviously, the drawings described in the following are only some of the embodiments of the present application and not limit the present application. Among them:

[0034] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions of the present application, but the terms can vary according to the intention of those of ordinary skill in the art, precedents, or new technology in the art. Also, specific terms can be selected by the applicant, and in this case, the detailed meanings thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the general description of the present application.

[0035] Referring to Figure 1 and Figure 2 , the present embodiment provides a multi-stage crushing device for food product preparation. When the multi-stage crushing device for food product preparation is used to crush materials, it needs to be placed in a liquid. In most use scenarios, the liquid is pure water. Of course, the liquid can also be other types of extraction liquid. The container for loading the liquid can use an external pool structure. For example, when producing, a pool 800 containing liquid is built. The crushing device is directly placed in the pool 800. The crushing device includes a frame 100, which is a housing and is directly placed in the liquid. The frame 100 includes a water-remote part 101 that is not submerged in water. The frame 100 also includes a water-into part 102 that is at least partially located in the liquid, such as Figure 2 , a pool 800 containing liquid is shown. The liquid level in the pool is shown with a dashed line. The relationship between the water-remote part 101 and the water-into part 102 and the liquid level is also shown.

[0036] Referring again to Figure 1 and Figure 2 , the crushing device also includes a crushing part 200 and a grinding part 300. The crushing part 200 is provided on the water-remote part 101. The grinding part 300 is provided on the water-into part 102. The crushing part 200 can crush the material, and the grinding part 300 can further grind the material, so that the material is ground into smaller particles, and the ingredients that need to be extracted in the material can better enter the liquid, thereby improving the extraction effect.

[0037] Referring to Figure 5 and Figure 6 , the crushing device also includes a water-into hopper 400. The water-into hopper 400 has a material inlet 401, an inner cavity 402, and a water outlet 403. The material inlet 401 and the water outlet 403 are located at both ends of the inner cavity 402, respectively. The water-into hopper 400 can move up and down relative to the liquid level in the pool 800. After the crushing part 200 crushes the material, the crushed material will fall into the liquid and float on the surface of the liquid. Therefore, the crushing device is suitable for crushing materials with a density less than water that can float on the surface of water.

[0038] Referring toFigure 1 And Figure 5 The crushing device further comprises a hopper driving member 500 connected with the water inlet hopper 400, and the hopper driving member 500 drives the water inlet hopper 400 to move up and down. When the water inlet hopper 400 is driven downward by the hopper driving member 500, the material inlet 401 is at least partially submerged in the liquid, and the liquid and the material can enter the water inlet hopper 400 through the material inlet 401. When the water inlet hopper 400 is driven upward by the hopper driving member 500, the liquid is discharged through the water outlet 403, and the material remains in the water inlet hopper 400.

[0039] The grinding member 300 can crush the material in the water inlet hopper 400. After the material is ground, the water inlet hopper 400 is lowered again by the hopper driving member 500, the liquid enters the inside of the water inlet hopper 400 and contacts the ground material, and the crushed material continues to enter the inside of the water inlet hopper 400 through the material inlet 401. When the hopper driving member 500 is raised again, the water drives the ground material with smaller particles to be discharged through the water outlet 403, and the material with larger particles remains in the water inlet hopper 400 for further grinding.

[0040] Therefore, the embodiment can preliminarily crush the material by the crushing member, and then collect the crushed material from the water into the water inlet hopper 400 through the rising and falling of the water inlet hopper 400, and grind the material in the water inlet hopper 400 by the grinding member 300 to make the material into smaller particles, and the effect is:

[0041] Firstly, the material can be crushed into smaller particles by the crushing and grinding processes, so that the components to be extracted in the material can better enter the liquid.

[0042] Secondly, during the rising and falling of the water inlet hopper 400, the liquid can carry the ground material with smaller particles in the water inlet hopper 400 away from the water inlet hopper 400, and the material with larger particles remains in the water inlet hopper 400 for further grinding, so that all the material can be crushed into smaller particles.

[0043] Thirdly, the liquid enters and discharges the water inlet hopper 400 during the grinding process, so that the water inlet hopper 400 can maintain good cleanliness, and the problem of serious oxidation of the material remaining in the water inlet hopper 400 can be avoided.

[0044] Specifically, referring again to Figure 1 And Figure 2The crushing piece 200 comprises a crushing driving part 201 and crushing rollers 202 connected with the crushing driving part 201. The crushing rollers 202 are generally two in number, and the crushing rollers 202 are provided with crushing protrusions. When the material contacts the crushing rollers 202, the material can be preliminarily crushed through the rotating and extruding of the intersecting crushing protrusions. The crushing driving part 201 is preferably a motor. The same motor can drive the two crushing rollers 202 to rotate, or two motors can drive the two crushing rollers 202 to rotate respectively. The rotating directions of the two crushing rollers 202 are opposite. The material reaches the two crushing rollers 202 from above, and the two crushing rollers 202 can extrude and crush the material. The crushed material falls into the liquid below.

[0045] Please refer to Figure 5 and Figure 6 The grinding piece 300 comprises a grinding driving part 301 and a grinding disc 302 connected with the grinding driving part 301. The frame 100 is further provided with a secondary support 105, which is mainly used for mounting the grinding piece 300, such as Figure 5 The grinding driving part 301 is a motor, which is fixedly installed on the secondary support 105. The output shaft of the grinding driving part 301 is connected with the grinding disc 302. When the grinding driving part 301 works, the grinding disc 302 can be driven to rotate. When the water inlet hopper 400 moves upward, the grinding disc 302 can enter the inside of the water inlet hopper 400 to press and grind the material in the water inlet hopper 400.

[0046] Preferably, please refer to Figure 5 The inner cavity 402 of the water inlet hopper 400 is cylindrical, and the grinding disc 302 is disc-shaped. The diameter of the grinding disc 302 is adapted to the inner diameter of the water inlet hopper 400, so that the grinding disc 302 can enter the inside of the water inlet hopper 400 and the gap between the grinding disc 302 and the radial inner wall of the water inlet hopper 400 is minimized, thereby enabling the grinding disc 302 to sufficiently grind the material in the water inlet hopper 400.

[0047] Please refer to Figure 5 The hopper driving piece 500 can be a hydraulic telescopic structure or an electric telescopic mechanism. Therefore, the hopper driving piece 500 has a telescopic end 501 connected with the water inlet hopper 400. During work, the telescopic end 501 can reciprocatingly extend and shorten to drive the water inlet hopper 400 to reciprocatingly ascend and descend. Figure 5 The number of the hopper driving pieces 500 is two. The two hopper driving pieces 500 are connected with the water inlet hopper 400 and are installed on the secondary support 105.

[0048] In another embodiment, please refer to Figure 3 The frame 100 is provided with a blocking part 103, and the inside of the frame 100 forms a material concentration space 104 through the blocking part 103. The blocking part 103 is a plate-shaped structure fixed inside the frame 100, and the bottom end of the blocking part 103 needs to extend into the liquid to form a material concentration space 104 with the entire frame 100. After the material is broken by the breaking piece 200, it will fall into the material concentration space 104. Because of the blocking of the frame 100 and the blocking part 103, the floating material cannot enter the material concentration space 104 with the water. Therefore, in this embodiment, the water inlet hopper 400 needs to be arranged in the material concentration space 104. When the material inlet 401 of the water inlet hopper 400 is partially submerged in water, the floating material inside the material concentration space 104 can enter the inside of the water inlet hopper 400.

[0049] By forming the material concentration space 104, the broken material can be concentrated and will not float everywhere, causing the problem of not being able to enter the water inlet hopper 400 for grinding. At the same time, because of the concentration of the broken material, the efficiency of the water inlet hopper 400 in collecting broken material can be improved.

[0050] As an optional embodiment, please refer to Figure 4 and Figure 7 The breaking device further comprises a limiting frame 600, which is installed on the frame 100, and the water inlet hopper 400 is installed on the limiting frame 600. In this embodiment, the limiting frame 600 is directly installed on the blocking part 103. The limiting frame 600 comprises a closed ring 601, which is fixed on the combination part. A plurality of protruding rods 602 are fixedly connected to the closed ring 601. The ends of the plurality of protruding rods 602 away from the closed ring 601 are provided with a bottom plate 603. When the water inlet hopper 400 is installed on the limiting frame 600, the radial outer wall of the water inlet hopper 400 is attached to the closed ring 601.

[0051] Preferably, the radial side wall of the water inlet hopper 400 is provided with a side groove 407. When the water inlet hopper 400 is installed on the limiting frame 600, the protruding rods 602 are located inside the side groove 407, which can effectively prevent the water inlet hopper 400 from rotating and stabilize the water inlet hopper 400. When the hopper driving piece 500 is extended and retracted, the water inlet hopper 400 moves on the limiting frame 600. When the water inlet hopper 400 moves upward, it will not completely separate from the closed ring 601, thereby avoiding the generation of a gap between the water inlet hopper 400 and the closed ring 601, and reducing the problem that the broken material escapes to the outside of the material concentration space 104 through the gap.

[0052] Please refer to Figure 6 and Figure 7The blocking piece 700 is installed on the limiting frame 600, and when the water inlet hopper 400 moves downward, the blocking piece 700 can block the drain port 403. The purpose is to avoid water entering the water inlet hopper 400 through the drain port 403 when the water inlet hopper 400 is lowered, so that the water level in the water inlet hopper 400 and the water level in the pool 800 are equal, and water and materials cannot enter the water inlet hopper 400 through the inlet 401.

[0053] During the lowering of the water inlet hopper 400, the blocking piece 700 can block the drain port 403, so that when the water inlet hopper 400 continues to descend, the liquid level in the water inlet hopper 400 is lower than the water level in the pool 800, so that the water in the pool 800 can carry the materials into the water inlet hopper 400 through the inlet 401.

[0054] Specifically, the blocking piece 700 includes a slide column 701 installed on the limiting frame 600, a spring 702 sleeved outside the slide column 701, and a plug 703 arranged at the end of the slide column 701. When the plug 703 enters the drain port 403, the drain port 403 can be blocked.

[0055] A hole is formed in the bottom plate 603 for the slide column 701 to pass through. The spring 702 is sleeved outside the slide column 701. One end of the spring 702 abuts against the plug 703, and the other end abuts against the bottom plate 603. During the lowering of the water inlet hopper 400, the plug 703 can block the drain port 403 to avoid water entering the water inlet hopper 400 through the drain port 403 all the time. As the water inlet hopper 400 continues to descend, the plug 703 can press the spring 702 to obtain a descending stroke, and the spring 702 can keep the plug 703 in a state of blocking the drain port 403.

[0056] Please refer to Figure 6 The drain port 403 has an inner recess 4031. A plurality of water holes 4032 are formed in the cavity wall of the inner recess 4031. Water in the water inlet hopper can be discharged through the water holes 4032. The shape and size of the inner recess 4031 are matched with the shape and size of the plug 703, for example Figure 6 and Figure 7 The inner recess 4031 and the plug 703 are both cylindrical, and the inner diameter of the inner recess 4031 and the diameter of the plug 703 are matched. During the lowering of the water inlet hopper 400, the plug 703 can enter the inside of the inner recess 4031, and the radial side wall of the plug 703 abuts against the cavity wall of the inner recess 4031, so as to achieve the effect of blocking the water holes 4032.

[0057] In one embodiment, as shown in Figure 6 and Figure 7The limiting frame 600 is inclined, and the water inlet hopper 400 is installed on the limiting frame 600, so the water inlet hopper 400 is also inclined. The top end of the limiting frame 600 is located in the material concentration space 104, and the bottom end of the limiting frame 600 is located outside the material concentration space 104. When the water inlet hopper 400 is lowered to the lowest position, the material inlet 401 of the water inlet hopper 400 can be located in the material concentration space 104 due to the limiting of the top end of the limiting ring. When the water inlet hopper 400 is raised to the highest position, water is discharged from the water outlet 403, and the discharged water and the ground material carried by the water enter outside the material concentration space 104.

[0058] If the water inlet hopper 400 is vertically arranged, water will enter the interior of the material inlet 401 from all directions when the material inlet 401 is not immersed in water. In this embodiment, because the water inlet hopper 400 is inclined, the material inlet 401 of the water inlet hopper 400 is inclined towards the material concentration space 104, which can better enable the material in the material concentration space 104 to enter the interior of the water inlet hopper 400 through the material inlet 401, thereby improving the efficiency of material collection.

[0059] Please refer to Figure 8 and Figure 9 The water inlet hopper 400 has a concave hopper bottom 405, and the water outlet 403 is arranged on the hopper bottom 405. The position of the hopper bottom 405 is higher than the bottom of the surrounding wall 406 of the water inlet hopper 400. The purpose of this arrangement is to avoid the problem that the water inlet hopper 400 completely separates from the limiting frame 600 during the rising process. In order to enable the water in the interior of the water inlet hopper 400 to be discharged as much as possible, the water outlet 403 needs to be separated above the water surface. Only after completely separating from the water surface, the water in the interior of the water inlet hopper 400 can be reduced as much as possible. Only part of the water will remain at the bottom corner of the inclined water inlet hopper 400. The remaining water can be effectively squeezed out of the water inlet hopper 400 when the grinding disc 302 enters.

[0060] Please refer to Figure 8 The dashed line shows the appropriate water level in this embodiment. When the water inlet hopper 400 is in the lowest position, the water can at least partially immerse the material inlet 401, ensuring that the water can enter the interior of the water inlet hopper 400 through the material inlet 401. Please refer to Figure 9 When the water inlet hopper 400 is in the highest position, the water outlet 403 can separate from the water surface, ensuring that the water therein can be discharged in large quantities. At this time, the surrounding wall 406 of the water inlet hopper 400 can still be in close contact with the sealing ring.

[0061] In this way, the enclosing wall 406 of the water inlet hopper 400 does not completely separate from the enclosing ring 601 before the water inlet hopper 400 completely separates from the water surface, so that no gap is formed between the enclosing wall 406 of the water inlet hopper 400 and the enclosing ring 601 during the rising of the water inlet hopper 400, and the material floating on the water surface in the material concentration space 104 cannot escape to the outside through the gap, thereby ensuring that all the crushed materials can be concentrated in the material concentration space 104 to wait for grinding by the grinding member 300, so that all the materials can be ground into smaller particles.

[0062] Finally, it should be noted that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present application.
