[0002] A meat grinder usually includes a main machine, a meat grinder and a screw. The screw extends into the meat grinder and is connected to the driving part of the main machine. After the main machine is started, the screw is driven to rotate, so that the meat filling is transported and minced by the continuous rotation of the screw.

[0003] In the existing meat grinder, the meat feeding channel is perpendicular to the axis of the main machine and the meat outlet channel, so that the entire meat grinder occupies a large space. Summary of the invention

[0004] In order to solve at least one of the problems existing in the above-mentioned prior art, according to one aspect of the present invention, a meat grinder is provided, comprising: a main machine; a meat grinder having a feeding part and a meat grinding part, wherein the feeding part and the meat grinding part have a feeding channel and a meat grinding chamber, and the feeding channel and the meat grinding chamber are connected; a knife plate, located between the meat grinder and the main machine; a screw, used for pushing the meat in the meat grinding chamber and cooperating with the knife plate to chop the meat; wherein the axis of the main machine, the axis of the feeding channel, the axis of the meat grinding chamber and the axis of the connecting shaft all extend in the vertical direction.

[0005] In this way, by arranging the axis of the main machine, the axis of the feed channel, the axis of the meat grinder chamber and the axis of the connecting shaft in a manner of extending in the vertical direction, a smaller projection area is provided on the supporting plane, so that the entire meat grinder can be effectively reduced in size, the space occupied is reduced, and the miniaturization development of the meat grinder is realized.

[0006] In some embodiments, a meat outlet structure is further included for discharging the meat filling chopped by the screw and the knife plate. The meat outlet structure is connected between the meat mincing part and the main machine and accommodates the knife plate. The screw passes through the meat outlet structure.

[0007] In this way, by providing a meat discharge structure, the meat material chopped by the cutting knife and the cutting plate can be guided to the discharge structure, so that the meat filling can be collected at the discharge port of the discharge structure.

[0008] In some embodiments, the meat discharge structure has a discharge portion, the discharge portion extends in a direction away from the main machine, the discharge portion has a discharge channel, and the discharge portion forms a discharge port.

[0009] In this way, by providing a discharge channel with a certain extension length, it is convenient to collect the meat filling. For example, when the meat filling is used to make sausages, it is convenient to put the casing on the discharge portion with a certain length.

[0010] In some embodiments, the bottom wall of the discharge portion is inclined downward toward the bottom of the main machine.

[0011] In this way, the meat filling can slide to the discharge port according to its own gravity and fall out from the discharge port.

[0012] In some embodiments, a mounting groove is provided on the side of the meat mincing portion facing the main machine, the mounting groove is used to install the knife board, and the height of the mounting groove is less than the thickness of the knife board, and the meat outlet structure has a support platform, and the support platform is used to support the knife board.

[0013] In this way, when the meat grinder is installed in the meat outlet structure, after the meat grinder is screwed into the meat outlet structure, the knife plate can be pressed against the support table through the top wall of the installation groove to prevent the knife plate from shaking during use.

[0014] In some embodiments, the meat discharge structure further has a material receiving groove, which is located below the knife plate and is connected to the discharge channel. The bottom wall of the material receiving groove is inclined downward toward the bottom of the main machine, and the angle between the bottom wall of the material receiving groove and the horizontal plane is smaller than the angle between the bottom wall of the discharge part and the horizontal plane.

[0015] In this way, the meat filling can smoothly slide from the material receiving trough to the material discharging part.

[0016] In some embodiments, the meat outlet structure is provided with an isolation column, the isolation column extends in the direction of the meat mincer, and the screw rod passes through the isolation column.

[0017] In this way, by providing an isolation column and an isolation pad in the isolation column, the screw rod passes through the isolation pad and then is electrically connected to the main unit, thereby preventing blood from flowing into the main unit.

[0018] In some embodiments, the screw rod includes a connecting shaft and a cutter disposed on the connecting shaft, the cutter is accommodated in the minced meat cavity, the connecting shaft is used to be electrically connected to the main machine, the cutter includes a plurality of spaced-apart spiral ribs and at least one blade disposed along the circumference of the connecting shaft, the blade is used to cooperate with the knife plate.

[0019] In this way, the cutter is arranged to include two parts, the meat is transported through the spiral ribs to increase the transmission speed and pressure of the meat, and then the meat is chopped through the contact and cooperation between the cutter and the knife plate, and then gradually leaks from the knife plate into the meat outlet structure.

[0020] In some embodiments, the pitch between each two adjacent spiral ribs decreases sequentially from the direction of the minced meat to the main machine.

[0021] In this way, the pitch from the meat feeding position to the cutting direction is set to decrease in sequence. The meat first enters the pitch between the spiral ribs with a larger position so that there is more space to store the meat. As the pitch between the spiral ribs becomes smaller in the cutting direction, there is a greater squeezing effect between the spiral ribs, and the squeezing effect is stronger, thereby achieving the purpose of mincing the food after squeezing.

[0022] In some embodiments, the vertical distance between the crest of the spiral rib and the connecting axis gradually increases along the direction from the minced meat to the main machine.

[0023] In this way, the contact area between the food and the spiral ribs gradually increases from top to bottom, and thus the squeezing force of the spiral ribs on the food gradually increases from top to bottom, making the spiral ribs more effective in crushing the food.

[0046] The above-mentioned meat grinder 100 has a smaller projection area on the support plane by arranging the axis of the main machine 10, the axis of the feed channel 211, the axis of the meat grinder chamber 221 and the axis of the connecting shaft 31 in a manner of extending in the vertical direction, so that the entire meat grinder 100 can be effectively reduced in size, reduce the space occupied, and realize the miniaturization development of the meat grinder 100.

[0047] Among them, the meat grinder 100 in this embodiment is used in a vertical direction when in use, and the axis of the main unit 10, the axis of the feed channel 211, the axis of the meat grinder cavity 221 and the axis of the connecting shaft 31 all extend in the vertical direction, so as to facilitate the addition of meat from the feed part 21 arranged in the vertical direction.

[0048] See also Figure 4 and Figure 5 In one embodiment of the present invention, in order to facilitate the transportation of meat in the meat grinder 22, at least one convex rib 222 is provided on the inner wall of the meat grinder 22 in this embodiment. The convex rib 222 is arranged from top to bottom in the direction from the feed portion 21 to the bottom of the main machine 10. By providing the convex rib 222, a certain cooperation effect can be formed with the propulsion screw 30, thereby increasing the propulsion force, allowing the meat to be output from the meat grinder 22 more quickly, and at the same time, it can also prevent the meat from accumulating in the meat grinder cavity 221.

[0049] The convex rib 222 may be one or more of a rotating rib, an inclined rib or a straight rib, so as to cooperate with the screw 30. Specifically, the convex rib 222 in this embodiment is an inclined rib.

[0050] In one embodiment of the present invention, in order to facilitate the installation and positioning of the screw 30, a positioning groove 223 protruding in a direction away from the main machine 10 is provided at the top of the meat grinder 22 in this embodiment.

[0051] Among them, the inlet 224 of the meat mincing part 22 in this embodiment that connects to the feeding part 21 is arranged on the side wall of the meat mincing part 22, so as to avoid affecting the setting of the positioning groove 223 when the inlet 224 is set at the top of the meat mincing part 22, and the way of being arranged on the side wall of the meat mincing part 22 does not interfere with the positioning groove 223.

[0052] See also Figures 1 to 3 as well as Figure 6 to Figure 7 In one embodiment of the present invention, in order to facilitate the outflow of meat filling after the meat is minced, the meat grinder 100 in this embodiment also includes a meat discharge structure 50, which is connected between the meat grinder 22 and the main machine 10. The connecting shaft 31 passes through the meat discharge structure 50 and accommodates the knife plate 40, and has a discharge port 51. The meat grinder cavity 221 and the discharge port 51 are connected in sequence. The discharge port 51 is used to flow out the meat minced by the cutting knife 32 and the knife plate 40. Therefore, by providing the meat discharge structure 50, the meat minced by the cutting knife 32 and the knife plate 40 can be guided to the discharge port 51, so that the meat filling can be collected at the discharge port 51.

[0053] Specifically, the meat outlet structure 50 in this embodiment includes a connecting portion 52, a material containing portion 53, a material outlet portion 54 and a support platform 55. An internal thread 521 is provided on the inner wall of the connecting portion 52, and an external thread 225 is provided on the outer wall of the meat mincing portion 22. The meat mincing channel 20 can be installed on the meat outlet structure 50 by cooperating with the internal thread 521 on the connecting portion 52 and the external thread 225 on the meat mincing portion 22.

[0054] In order to facilitate the installation of the knife board 40, the support platform 55 in this embodiment is arranged between the connecting portion 52 and the material receiving portion 53, and is used to support the knife board 40 so that the knife board 40 and the cutting knife 32 cooperate to cut the meat.

[0055] Among them, the material receiving portion 53 and the material discharging portion 54 in this embodiment are connected and are located below the knife plate 40. The material receiving portion 53 forms a material receiving groove 531, and the material receiving groove 531 is connected to the material discharging port 51. The material receiving groove 531 is used to receive the meat filling that falls out of the knife plate 40, and the material discharging portion 54 forms the above-mentioned material discharging port 51, so that the meat filling falls out of the knife plate 40 and first falls onto the top wall of the material receiving portion 53, and then flows out from the material discharging channel 541 of the material discharging portion 54.

[0056] It can be understood that in order to facilitate the meat filling to flow smoothly from the receiving portion 53 to the discharging portion 54, the bottom wall 532 of the receiving trough 531 in this embodiment is configured to be inclined downward toward the bottom direction of the main unit 10, so that the meat filling can slide into the discharging portion 54 according to its own gravity.

[0057] It can be understood that in order to facilitate the meat filling to slide out smoothly from the discharge portion 54, the discharge portion 54 in this embodiment forms a discharge channel 541, and the discharge channel 541 extends in a direction away from the main unit 10, and the discharge portion 54 forms a discharge port 51, so that the meat filling can be collected easily by providing the discharge channel 541 with a certain extension length. For example, when the meat filling is used to make sausages, it is convenient to put the casing on the discharge portion 54 with a certain length.

[0058] It can be understood that in order to facilitate the meat filling to flow out from the discharge portion 54, the bottom wall 542 of the discharge portion 54 in this embodiment is configured to be inclined downward toward the bottom direction of the main unit 10, so that the meat filling can slide to the discharge port 51 according to its own gravity and fall out of the discharge port 51.

[0059] In addition, the angle between the bottom wall of the material receiving groove 531 and the horizontal plane in this embodiment is smaller than the angle between the bottom wall of the material discharging portion 54 and the horizontal plane, so that the meat filling can slide smoothly from the material receiving groove 531 to the material discharging portion 54.

[0060] In addition, in order to prevent the meat filling from being blocked in the discharge portion 54, the cross-sectional area of ​​the discharge portion 54 in this embodiment is set to gradually increase in the direction away from the main unit 10, so that the meat filling can easily slide out of the discharge portion 54 and avoid being blocked in the discharge channel 541.

[0061] In order to match the structure of the main unit 10 , the meat outlet structure 50 in this embodiment also includes support ribs 56 , which are connected to the bottom of the connecting portion 52 and are used to be supported in the cavity 11 of the main unit 10 .

[0062] It can be understood that in order to prevent the blood produced by the meat filling from flowing into the main unit 10, the meat outlet structure 50 in this embodiment is provided with an isolation column 57, and the isolation column 57 extends in the direction of the meat grinder 20. The connecting shaft 31 passes through the isolation column 57, and an isolation pad can be set in the isolation column 57. Therefore, by setting the isolation column 57, the connecting shaft 31 can pass through the isolation pad and then be electrically connected to the main unit 10, thereby preventing blood from flowing into the main unit 10.

[0063] See also Figure 2 , Figure 3 as well as Figure 5In the present embodiment, a through hole is formed in the knife plate 40 for the minced meat to flow out, and the knife plate 40 is installed in the meat grinder 22 at one end facing the main machine 10 and supported by the support platform 55. In order to fix the knife plate 40 during use, the meat grinder 22 in the present embodiment is provided with a mounting groove 226 on the side facing the main machine 10. The knife plate 40 is installed in the mounting groove 226 and supported by the support platform 55. The height H of the mounting groove 226 is less than the thickness of the knife plate 40. Therefore, when the meat grinder 20 is installed in the meat outlet structure 50, after the meat grinder 20 is tightened in the meat outlet structure 50, the top wall of the mounting groove 226 can press the knife plate 40 on the support platform 55 to prevent the knife plate 40 from shaking during use.

[0064] See also Figure 3 and Figure 8 In one embodiment of the present invention, in order to achieve smooth transportation and cutting of meat, the cutter 32 includes a plurality of spiral ribs 321 separated from each other and at least one blade 322 arranged along the circumference of the connecting shaft 31. The blade 322 is used to cooperate with the knife plate 40. Thus, by setting the cutter 32 to include two parts, the meat is transported through the spiral ribs 321, the transmission speed and pressure of the meat are increased, and then the meat is chopped through the contact and cooperation between the cutter 32 and the knife plate 40, and then gradually leaks from the knife plate 40 into the meat outlet structure 50.

[0065] Among them, in order to facilitate the transportation of meat, the pitch between each two adjacent spiral ribs 321 in this embodiment decreases successively from the direction of the meat grinder 20 to the main machine 10, so that the pitch at the meat input position to the pitch in the direction of the blade 322 is set to decrease successively. The meat first enters the pitch between the spiral ribs 321 with a larger position, so that there is more space to store the meat. As the pitch between the spiral ribs 321 becomes smaller in the direction of the cutter, there is a greater squeezing effect between the spiral ribs 321, and the squeezing effect is stronger, thereby achieving the purpose of squeezing and mincing the food.

[0066] Specifically, see Figure 8 , take three sections of spiral ribs 321 as an example, the spacing between the first and second spiral ribs 321 from top to bottom is P1, and the spacing between the second and third spiral ribs 321 is P2, wherein P1>P2. Therefore, the pitch P1 between the first two spiral ribs 321 is larger, and there is a larger space to store more food materials, which is convenient for feeding and makes feeding smoother. The food materials enter the pitch P2 of the spiral ribs 321 through the pushing and guidance of the spiral ribs 321. Since the pitch P2 of the spiral ribs 321 is smaller than P1, the pitch of the spiral ribs 321 becomes smaller, and the meat material has a greater squeezing effect at the pitch P2 position, thereby achieving the purpose of squeezing and mincing the food materials.

[0067] In addition, in order to further ensure the crushing effect on the meat, the vertical distance between the tooth top of the spiral rib 321 and the connecting shaft 31 in this embodiment gradually increases in the direction from the meat grinder 20 to the main unit 10, that is, the distance from the tooth top to the tooth bottom of the spiral rib 321 in the direction perpendicular to the axial centerline of the connecting shaft 31 is the tooth profile height D, and the tooth profile heights of the spiral rib 321 from top to bottom along the axial direction of the connecting shaft 31 are D1, D2, D3...Dn, then Dn>...D3>D2>D1, therefore, the contact area between the food and the spiral rib 321 gradually increases from top to bottom, and thus the extrusion force of the spiral rib 321 on the food gradually increases from top to bottom, so that the spiral rib 321 can crush the food more fully.

[0068] See also Figure 1 , Figure 2 as well as Fig. 9 The host 10 in the embodiment of the present invention includes a main body 12 and a cavity 11 arranged on the main body 12, and the cavity 11 is used to accommodate part of the meat grinder 20 and part of the meat outlet structure 50, so that the meat grinder 20 and the meat outlet structure 50 can be stably installed on the host 10.

[0069] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
