Description

Technical Field

[0050] See Figures 1 to 3 , in this embodiment, a rasp grinder for grinding corn is provided, including:

[0051] A base 1, provided with a discharge port 11;

[0052] A housing 2, disposed on the base 1. The top end of the housing 2 is provided with a feed port 24, and the feed port 24 is communicated with the discharge port 11 through a cavity inside the housing 2;

[0053] A round roller 3, vertically disposed inside the housing 2;

[0054] A first rasping knife mechanism 4, disposed inside the housing 2 close to the round roller 3, and the first rasping knife mechanism 4 is above the center of the round roller 3;

[0055] A baffle 5, disposed inside the housing 2. The baffle 5 extends from the feed port 24 to the first rasping knife mechanism 4, and the baffle 5 is used to block the corn kernels from passing over the first rasping knife mechanism 4;

[0056] A second rasping knife mechanism 6, disposed between the inner side wall of the housing 2 and the round roller 3. The second rasping knife mechanism 6 is disposed close to the round roller 3. The second rasping knife mechanism 6 and the center of the round roller 3 are at the same horizontal height, and the second rasping knife mechanism 6 is disposed close to the first rasping knife mechanism 4; and

[0057] Two ring structures 32, respectively coaxially fixed on the left and right sides of the round roller 3, and the first rasping knife mechanism 4 and the second rasping knife mechanism 6 are respectively disposed between the two ring structures 32;

[0058] Among them, the gap between the second rasping knife mechanism 6 and the round roller 3 is smaller than the gap between the first rasping knife mechanism 4 and the round roller 3.

[0059] It should be noted that the round roller 3 in this embodiment is connected to the driving motor through a transmission belt, so that the driving motor is used to rotate the round roller 3.

[0060] In addition, the round roller 3 in this embodiment may be a cylindrical structure.

[0061] During use, start the driving motor to make the round roller 3 rotate towards the first file and grind mechanism 4. Pour the peeled corn kernels from the feed port 24 above the housing 2. Taking advantage of the fact that the first file and grind mechanism is higher than the second file and grind mechanism, under the drive of the round roller 3, the corn kernels move towards the first file and grind mechanism 4. Under the restriction of the baffle 5 and the two ring structures 32, the corn kernels can only pass through the gap between the first file and grind mechanism 4 and the round roller 3. Thus, the first file and grind mechanism 4 and the round roller 3 are used to grind and roll the corn kernels for the first time, making the corn kernels pass through the first file and grind mechanism 4 and become corn dregs, and then continue to come to the second file and grind mechanism 6 as the round roller 3 rotates. Then, taking advantage of the fact that the gap between the second file and grind mechanism 6 and the round roller 3 is smaller than the gap between the first file and grind mechanism 4 and the round roller 3, and the blocking of the two ring structures 32 on the corn dregs, the corn dregs can only pass through between the second file and grind mechanism 6 and the round roller 3, so as to further grind the corn dregs, fully grind the corn dregs, achieving a good grinding effect, and then flowing out from the discharge port 11 of the base 1 for subsequent process treatment. Thus, the problem in the prior art that the corn kernels cannot be effectively ground is solved.

[0062] See Figures 1 to 3 Furthermore, a plurality of saw teeth strips 31 are provided on the round roller 3. The plurality of saw teeth strips 31 are evenly distributed along the circumference of the round roller 3. The tip of each saw tooth of each saw teeth strip 31 points radially outward of the round roller 3.

[0063] The first file and grind mechanism 4 includes a plurality of first file and grind plates 41. One side edge of each first file and grind plate 41 is a first serrated edge. The plurality of first file and grind plates 41 are stacked together. The first serrated edge of each first file and grind plate 41 points towards the round roller 3.

[0064] During the rotation of the round roller 3, the tip of the saw tooth of the saw teeth strip 31 is used to pass through between the teeth of the first serrated edge of each first file and grind plate 41.

[0065] See Figures 1 to 3 Furthermore, the second file and grind mechanism 6 includes a plurality of second file and grind plates 61. One side edge of each second file and grind plate 61 is a second serrated edge. The plurality of second file and grind plates 61 are stacked together. The second serrated edge of each second file and grind plate 61 points towards the round roller 3.

[0066] During the rotation of the circular roller 3, the tips of the saw teeth of the saw rack 31 are adapted to pass between the teeth of the second serrated edge of each of the second filet knife plates 61.

[0067] In view of the problem that corn kernels are slippery and not easy to grind after being mixed with water, in this embodiment, on the one hand, the characteristics that the first filet knife plate 41 and the second filet knife plate 61 are respectively meshed with multiple saw racks 31 on the circular roller 3 in a staggered manner are utilized to break the corn kernels or corn grits; on the other hand, the multiple first filet knife plates 41 and the multiple second filet knife plates 61 are arranged in an overlapping manner, and the tips of the saw teeth of the saw rack 31 are adapted to pass between the teeth of the multiple first filet knife plates 41 and the second filet knife plates 61, so as to extend the filing process of the saw teeth and ensure the filing effect.

[0068] See Figures 1 to 3 , Further, the housing 2 includes an upper housing 212, a middle housing 222 and a lower housing 232. The upper housing 212, the middle housing 222 and the lower housing 232 are detachably connected together from top to bottom. The feed inlet 24 is arranged at the top of the upper housing 212.

[0069] The baffle 5 is detachably arranged in the upper housing 212;

[0070] The first filet knife mechanism 4 is detachably arranged in the middle housing 222;

[0071] The second filet knife mechanism 6 is detachably arranged in the lower housing 232 and is arranged close to the middle housing 222.

[0072] By utilizing that the baffle 5, the first filet knife mechanism 4 and the second filet knife mechanism 6 are all detachably arranged in the housing 2, the filing performance of the fileting machine for different materials is expanded. For example, when it is necessary to file potatoes, by separating the upper housing 212 from the middle housing 222, the baffle 5 and the first filet knife mechanism 4 are removed, and only the second filet knife mechanism 6 is retained for potato filing.

[0073] When only corn grits need to be filed, by removing the middle housing 222 and the upper housing 212 and removing the second filet knife mechanism 6, only the first filet knife mechanism 4 and the baffle 5 are retained.

[0074] See Figures 1 to 3, Further, a first tool holder 42 is provided on the inner side wall of the middle housing 222. The first tool holder 42 is arranged close to the arc surface of the round roller 3 at the top end of the middle housing 222. Two opposite side walls of the middle housing 222 are provided with first mounting grooves 43. The two first mounting grooves 43 are located on the left and right sides above the first tool holder 42. The first mounting grooves 43 extend along the tangent direction of the round roller 3, and the first mounting grooves 43 are communicated with the top surface of the middle housing 222.

[0075] The first file and grind tool plate 41 includes a first cross plate and a first longitudinal plate. The first cross plate and the first longitudinal plate are spliced into a T-shaped plate structure. The left and right ends of the first file and grind tool plate 41 are respectively placed in one of the first mounting grooves 43. The edge of the longitudinal end of the first file and grind tool plate 41 is the first serrated edge. A plurality of first file and grind tool plates 41 are fixed on the first tool holder 42 by threaded fasteners.

[0076] The lower end surface of the upper housing 212 completely covers the two first mounting grooves 43.

[0077] See Figures 1 to 3 , Further, the first file and grind tool plate 41 is provided with a first through hole. By inserting a first bolt into the first through hole, the first file and grind tool plate 41 is fixed on the first tool holder 42. The first bolt is arranged at a distance from the side wall of each first through hole. The large head end of the first bolt presses on the first file and grind tool plate 41.

[0078] The first file and grind tool plate 41 is arranged at a distance from the inner wall of the first mounting groove 43.

[0079] The first file and grind mechanism 4 further includes a plurality of first longitudinal inserts and a plurality of first transverse inserts.

[0080] The plurality of first longitudinal inserts are used to be inserted into the longitudinal gaps between the two first mounting grooves 43 and the first file and grind tool plate 41.

[0081] The plurality of first transverse inserts are used to be inserted into the left and right transverse gaps between the two first mounting grooves 43 and the first file and grind tool plate 41.

[0082] When installing the first file and grind tool plate 41, according to the drying time, soaking time, etc. of the corn kernels, adjust the installation quantity of the first file and grind tool plate 41. Stack the determined quantity of first file and grind tool plates 41 together. Then disassemble the upper housing 212 and the middle housing 222. Place the stacked plurality of first file and grind tool plates 41 on the first tool holder 42, and make the left and right ends of the first file and grind tool plate 41 respectively placed in one of the first mounting grooves 43, so as to limit the plurality of first file and grind tool plates 41.

[0083] In addition, since the filing blades in this embodiment adopt the method of stacking multiple first filing plates 41, it is difficult to adjust the overall front, rear, left, and right positions of the multiple first filing plates 41.

[0084] To address this issue, in this embodiment, the extension length of the first longitudinal plate is adjusted by inserting the corresponding number of first longitudinal inserts, and the clearance between the first serrated edge and the saw tooth bar 31 is adjusted. At the same time, the left and right positions of the first transverse plate can also be adjusted by inserting different numbers of first transverse inserts on the left and right sides of the first transverse plate. Since the thicknesses of the first transverse insert and the first longitudinal insert are relatively thin, the relative positions of the first filing plates 41 can be accurately controlled by controlling the number of inserted first transverse inserts and first longitudinal inserts, thereby achieving accurate adjustment of the overall front, rear, left, and right positions of the multiple first filing plates 41.

[0085] Meanwhile, the first bolt is arranged at a distance from the side wall of each first through hole to prevent the first bolt from restricting the movement of the first filing plate 41. After adjusting the positions of all the first filing plates 41, by screwing the first bolt, the large head end of the first bolt presses on the first filing plate 41, playing a role in pressing and fixing the multiple first filing plates 41 and preventing the positioned multiple first filing plates 41 from moving.

[0086] Moreover, only by the pressing and fixing of the large head end of the first bolt, the space volume occupied by the pressing and fixing member is fully reduced.

[0087] In addition, taking advantage of the feature that the multiple first filing plates 41 are arranged on the top of the middle housing 222, when adjusting the positions of the first filing plates 41, only the upper housing 212 needs to be removed, and then the multiple first filing plates 41 on the top of the middle housing 222 can be adjusted. At the same time, the lower end surface of the upper housing 212 completely covers the two first installation grooves 43, preventing corn kernels from entering the first installation grooves 43 and ensuring that as many corn kernels as possible are filed.

[0088] See Figures 1 to 3 , further, a second tool holder 62 is provided on the inner side wall of the lower housing 232. The second tool holder 62 is close to the top end of the lower housing 232 and is arranged close to the arc surface of the round roller 3. Two opposite side walls of the lower housing 232 are provided with second installation grooves 63. The two second installation grooves 63 are located on the left and right sides above the second tool holder 62, and the second installation grooves 63 penetrate the top surface of the lower housing 232 along the vertical direction.

[0089] The second file sharpening plate 61 includes a second transverse plate 611 and a second longitudinal plate 612. The second transverse plate 611 and the second longitudinal plate 612 are spliced into a T-shaped plate structure. The left and right ends of the second file sharpening plate 61 are respectively placed in a second mounting groove 63. The longitudinal end edge of the second file sharpening plate 61 is the second serrated edge. A plurality of second file sharpening plates 61 are fixed to the second tool holder 62 by threaded fasteners.

[0090] The lower end surface of the middle housing 222 completely covers the two second mounting grooves 63 .

[0091] See also Figures 1 to 3 Furthermore, the second file sharpening plate 61 is provided with a second through hole 613, and a second bolt is inserted into the second through hole 613 to fix the second file sharpening plate 61 on the second tool holder 62. The second bolt is spaced apart from the side wall of each second through hole 613, and the large end of the second bolt presses on the second file sharpening plate 61;

[0092] The second file sharpening plate 61 is spaced apart from the inner wall of the second mounting groove 63.

[0093] The second file sharpening mechanism 6 further includes a plurality of second longitudinal inserts 64 and a plurality of second transverse inserts 65.

[0094] The plurality of second longitudinal inserts 64 are used to be inserted into the longitudinal gap between the two second mounting slots 63 and the second file sharpening plate 61.

[0095] The plurality of second transverse inserts 65 are used to be inserted into the transverse gaps on the left and right sides between the two second mounting slots 63 and the second file sharpening plate 61 .

[0096] Since the second file sharpening mechanism 6 is identical or similar to the first file sharpening mechanism 4, the overall front, rear, left and right positions of the plurality of second file sharpening plates 61 can be accurately adjusted respectively; the space occupied by the pressing and fixing parts is fully reduced by only the big head end of the second bolt; and as much corn residue as possible is ensured to be filed; therefore, the advantages of the second file sharpening mechanism 6 will not be further described.

[0097] See also Figures 1 to 3 Furthermore, the first file sharpening mechanism 4 further includes a first cover plate, which is arranged on the top of the plurality of first file sharpening plates 41 , and the first cover plate is used to cover the top of the plurality of first file sharpening plates 41 .

[0098] The second file sharpening mechanism 6 further includes a second cover plate 66. The second cover plate 66 is disposed on the tops of the plurality of second file sharpening plates 61, and the second cover plate 66 is used to cover the tops of the plurality of second file sharpening plates 61.

[0099] The first file sharpening plates 41 and the second file sharpening plates 61 are covered by the first cover plate and the second cover plate 66 respectively, so as to protect the plurality of first file sharpening plates 41 and the second file sharpening plates 61, and facilitate the disassembly and assembly of the first file sharpening plates 41 on the top and the second file sharpening plates 61 on the top.

[0100] See Figures 1 to 3 , further, a plurality of limiting blocks 211 are disposed in the upper housing 212. The plurality of limiting blocks 211 are respectively arranged on two opposite side walls of the upper housing 212 along the extending direction of the baffle 5, and the baffle 5 is clamped between the plurality of limiting blocks 211.

[0101] The plurality of limiting blocks 211 are used to prevent the baffle 5 from moving in the upper housing 212, and at the same time facilitate the disassembly and assembly of the baffle 5 in the upper housing 212.

[0102] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, and these changes and modifications will all fall within the protection scope of the present utility model.
