[0001] The utility model relates to the technical field of food cutting, in particular to a grate structure capable of adjusting the upper and lower positions. Background Art

[0002] With the development of social economy, people's living standards have gradually improved, and people's demand for bones and meat has gradually increased. Animal bones and meat are rich in nutritional value. In addition to protein, fat, and vitamins, bones also contain a large amount of calcium phosphate, collagen, osteonectin, etc. Drinking bone soup regularly can promote the development of adolescent bones and enhance the hematopoietic function of human bones; the collagen contained in bones can help to replenish blood and beautify the body. For the elderly, drinking some bone soup regularly can slow down the aging of bones; in addition, bones are warm in nature and have the effects of replenishing spleen qi, moistening the intestines and stomach, producing body fluids, replenishing the middle qi, and nourishing blood and strengthening bones.

[0003] As people's demand for bones and meat increases, the workload of cutting and processing bones and meat in the market has also increased. At present, when cutting bones and meat such as pig's trotters and chicken legs in the market, they are usually cut by manually operating cutting saws or bone chopping knives; there are the following problems: 1. The risk factor is high, and the fingers of the person operating the cutting tool are easily scratched by the cutting tool; 2. A large amount of raw material sawdust is generated during the manual cutting of bones and meat, and the loss of meat raw materials is large; 3. Manual cutting is inefficient and time-consuming and labor-intensive.

[0004] Some bones and meat are relatively thick, such as pork bones and cow bones. Even if electric cutting equipment is used to cut bones and meat, the cutting blade can easily get stuck in the bones, which will cause the bones to rotate at high speed with the cutting blade, easily causing the bones to be thrown out and injure surrounding personnel or equipment. Utility Model Content

[0005] The utility model aims to provide a grate structure capable of adjusting the upper and lower positions, so as to solve the problem that bones are stuck on a cutting blade and easily thrown out during the process of cutting bones with an electric cutting device.

[0034] Specifically, refer to Figure 4 , Figure 5 The grate structure includes two mounting bars 21 and a plurality of limiting bars 22. The two mounting bars 21 are arranged on the mounting frame 13 in parallel and at intervals by bolts. The length directions of the two mounting bars 21 are perpendicular to the feeding direction of the feeding mechanism. One mounting bar 21 is located at one end of the plurality of blades 3 close to the discharge end of the feeding mechanism, and the other mounting bar 21 is located at one end of the plurality of blades 3 away from the discharge end of the feeding mechanism. The plurality of limiting bars 22 are arranged between the two mounting bars 21 by bolts. The plurality of limiting bars 22 are parallel to each other, and the length directions of the plurality of limiting bars 22 are consistent with the feeding direction of the feeding mechanism. There is a gap between two adjacent limiting bars 22. There is a gap 23 for the corresponding blade 3 to pass downward, and only one blade 3 passes through each gap 23; when the material box 2 carrying bones and flesh passes under the multiple limit bars 22, the multiple limit bars 22 can confine the bones and flesh in the material box 2, which can prevent the bones and flesh from escaping from the material box 2 during the cutting process to a certain extent, and when the bones and flesh are stuck on the blade 3, the grate structure can separate the bones and flesh from the blade 3 to prevent the blade 3 from lifting the bones and flesh and rotating with the blade 3. The high-speed rotation of the bones and flesh with the blade 3 can easily damage the blade 3 on the other set of cutting shafts 14, and the bones and flesh may be thrown over the body during the high-speed rotation and cause harm to the surrounding personnel.

[0035] Example 2

When the height of the limit strip 22 needs to be adjusted, first loosen the locking nut 25, and then rotate the adjusting bolt 24 so that the adjusting bolt 24 moves upward or downward on the mounting strip 21. The upward or downward movement of the adjusting bolt 24 will drive the limit strip 22 to move upward or downward synchronously, and then tighten the locking nut 25 again to lock the limit strip 22 again.

[0037] Example 3

[0038] Based on Example 2, in this example, refer to Figure 4 , Figure 5 After the rod of the adjusting bolt 24 passes upward through the mounting strip 21 , a washer 28 and a safety nut 29 are sleeved thereon. The safety nut 29 presses the washer 28 against the corresponding mounting strip 21 , thereby achieving secondary fixation of the adjusting bolt 24 .

[0039] Example 4

[0040] Based on Example 3, in this example, refer to Figure 4 , Figure 5, multiple limit bars 22 include a horizontal section 30, two inclined sections 31 and two mounting sections 32. An upwardly inclined inclined section 31 is provided at both ends of the horizontal section 30, and a horizontally arranged mounting section 32 is provided at one end of the two inclined sections 31 away from the horizontal section 30. The above-mentioned horizontal and inclined refer to the relative to the horizontal ground after the grate structure is installed on the mounting frame 13; a through hole 26 is provided on the two mounting sections 32. The purpose of the upward structure at both ends of the limit bar 22 is to reduce the obstruction of the adjusting bolts 24 at both ends of the limit bar 22 on the bones and flesh passing below.

[0041] In other embodiments, reference Figure 3 , Figure 4 , Figure 5 The blade 3 is close to the discharge end of the chain feeding mechanism, and a chain limiting mechanism is arranged at the position of the frame 1 close to the discharge end of the chain feeding mechanism. The chain limiting mechanism includes a chain pressing plate 33, and the chain pressing plate 33 is located above the feeding chain 5. The chain pressing plate 33 is used to limit the feeding chain 5 on the sprocket. The two feeding chains 5 are each provided with a chain pressure plate 33 near the discharge end of the feeding mechanism. The upper part of the chain pressure plate 33 is detachably arranged on the mounting frame 13 above the frame 1 by a plurality of bolts, and the lower part confines the corresponding feeding chain 5 on the corresponding support plate, and further confines the two feeding chains 5 on the corresponding feeding sprocket 7. In fact, in the process of the blade 3 squeezing and cutting the bones and flesh in the material box 2, the stress conditions of the bones and flesh will keep changing as the material box 2 moves, resulting in uneven stress on the material box 2. For example, when the rear side of the material box 2 is stressed, the front side of the material box 2 is prone to tilt up, thereby driving the feeding chain 5 below to tilt up. The chain limiting mechanism can conveniently prevent the feeding chain 5 from tilting up, thereby preventing the equipment and the blade 3 from contacting the chain and being damaged.

[0042] In other embodiments, reference Figure 2 , Figure 3 , a partition 34 is provided in each of the plurality of material boxes 2, and the partition 34 divides the material box 2 into a splitting box 35 and a dicing box 36; a passage slot 4 is provided on the side wall of the splitting box 35, and a plurality of passage slots 4 are provided on the side wall of the dicing box 36; the cutting mechanism comprises a plurality of blades 3, and the total number of the passage slots 4 on the splitting box 35 and the dicing box 36 is the same as the number of the blades 3, and all the passage slots 4 on each material box 2 correspond to the plurality of blades 3 one by one; the inner bottom walls of the splitting box 35 and the dicing box 36 are provided with cutting slots 37 for cooperating with the blades 3 to cut bones and meat. Placing smaller bones and meat such as chicken legs in the splitting box 35 can conveniently cut the chicken legs in half directly, while placing larger bones and longer bones in the dicing box 36 can facilitate cutting the bones into multiple pieces by the plurality of blades 3.

[0043] In other embodiments, reference Figure 2 , Figure 3 The split half box 35 is provided with a detachable fixture, which is used to confine the bone and meat in the split half box 35; the fixture includes two fixtures, which have the same structure and shape, and the fixture includes a base 38, a clamping plate 39 and an expansion plate 40 arranged in sequence from bottom to top, a through mounting hole 41 is provided on the base 38, and bolt holes 42 are provided on both sides of the inner bottom wall of the split half box 35 along the feeding direction of the feeding mechanism, and the bolt holes 42 are provided with internal threads, and the bases 38 of the two fixtures are installed on the corresponding sides of the inner bottom wall of the split half box 35 by bolts, and the upper parts of the clamping plates 39 of the two fixtures shrink toward the middle of the split half box 35 and are used to clamp the bone and meat such as chicken legs, and the expansion plates 40 on the tops of the two fixtures extend and expand toward the outside of the split half box 35, so as to facilitate pressing the chicken legs into between the two clamping plates 39 through the two expansion plates 40. The fixture can be made of elastic metal material, such as a thin stainless steel plate. The clamping plate can be used to confine the chicken legs and other bones and meat in the splitting box 35 to prevent the blade 3 from shifting when cutting the chicken legs, thereby preventing the blade 3 from cutting crookedly.

[0044] In other embodiments, reference Figure 4 , Figure 6 A spacing 23 adjusting member is provided on the frame 1 near one end of the chain, and the spacing 23 adjusting member is used to adjust the spacing 23 between the feeding sprockets 7 at both ends of the feeding chain 5.

In this embodiment, since two feeding chains 5 are provided, two spacing 23 adjusting members are also provided, and the spacing 23 adjusting members are used to adjust one feeding chain 5 respectively.

[0045] Specifically, refer to Figure 4 , Figure 6A fixing plate 43 is provided on the frame 1 beside each feeding chain 5, and a fixing column 44 is provided on one side of the fixing plate 43 close to the discharge end of the feeding mechanism; the spacing 23 adjustment member includes an adjustment block 45, an adjustment screw 46 and an adjustment nut 47, a through notch 48 is provided on the fixing plate 43 in the horizontal direction, and a slide groove 49 is provided on the upper and lower surfaces of the adjustment block 45, the adjustment block 45 is located in the notch 48 of the fixing plate 43, and the upper wall of the notch 48 of the fixing plate 43 is located in the slide groove 49 above the adjustment block 45, and the lower wall of the notch 48 is located in the slide groove 49 below the adjustment block 45, and the adjustment block 45 and the fixing plate 43 are slidably matched; a fixing groove 50 is provided on the surface of the adjustment block 45, and the fixing groove 50 A through hole 51 is provided on one side wall near the corresponding fixed column 44, and a through hole 5226 is provided on the fixed column 44. One end of the adjusting screw 46 passes through the through hole 5226 and the through hole 51 in sequence and then extends into the fixed groove 50. The inner diameter of the through hole 5226 is larger than the outer diameter of the adjusting screw 46. A fixing nut 53 is fixedly welded on one end of the adjusting screw 46 located inside the fixed groove 50. The adjusting nut 47 is sleeved on the adjusting screw 46. The adjusting nut 47 is located on the rod section of the adjusting screw 46 between the adjusting block 45 and the fixed column 44, and the adjusting nut 47 is tightly pressed against the outer wall of the fixed column 44 away from the feeding direction of the feeding mechanism. The length direction of the adjusting screw 46 is consistent with the feeding direction of the feeding mechanism. Bearing holes are provided on both adjusting blocks 45, and both ends of the rotating shaft 6 are rotatably connected to the adjusting blocks 45 at the corresponding ends through bearings.

[0046] Reference Figure 4 , Figure 6 After the feeding chain 5 has been used for a period of time, it will wear out and make the feeding chain 5 loose. At this time, you can use pliers or other tools to clamp the fixing nut 53 so that it does not rotate, and use a wrench to twist the adjusting nut 47 on the other hand to make the adjusting nut 47 move in the direction away from the adjusting block 45. Since the fixing column 44 prevents the movement of the adjusting nut 47, the adjusting nut 47 has a tendency to move relative to the adjusting screw rod 46 toward the discharging end of the feeding mechanism, that is, the adjusting screw rod 46 has a tendency to move relative to the adjusting nut 47 away from the discharging end of the feeding mechanism. When the adjusting nut 47 is fixed, the adjusting screw rod 46 will drive the adjusting block 45 to move away from the discharging end of the feeding mechanism, thereby driving the rotating shaft 6 and the corresponding ends of the two feeding chains 5 to move toward an end away from the discharging end of the feeding mechanism. When the ends of the two feeding chains 5 close to the discharging end of the feeding mechanism are fixed, the tensioning of the two feeding chains 5 can be achieved.
