Description

Technical Field

[0001] The utility model belongs to the technical field of wheat grinding devices, and in particular relates to a wheat peeling and grinding device. Background Art

[0002] Before wheat is ground into flour, it needs to be screened, moistened with water, left to stand, and ground. The purpose of screening wheat is to screen out the dust, pebbles, etc. of the wheat seeds to ensure the purity of the flour after grinding. Moistening wheat with water means adding an appropriate amount of water to moisten the wheat during the screening process to increase the toughness of the wheat bran and reduce the mechanical strength of the wheat endosperm. When grinding, the wheat bran should not be ground too finely to affect the quality of the flour. It can also reduce the wear on the flour mill, reduce losses and energy consumption. Standing is to allow the water to thoroughly penetrate and moisten the wheat. There are two types of grinding, one is to remove the wheat husk, and the other is to grind the wheat into powder.

[0003] The grinding step of removing the wheat husk is particularly important. If the husk and other useless parts of wheat cannot be removed, the quality and taste of the flour will be seriously affected. At present, the grinding device used for wheat peeling has the same spacing between the inner and outer sand rollers, and the grinding force of the entire grinding section is consistent, which is not conducive to the full grinding of the wheat husk, thereby affecting the quality and taste of the subsequent flour. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a wheat peeling and grinding device, which is used to solve the technical problem that the grinding force of the current grinding device is consistent during peeling and grinding, resulting in insufficient grinding of the wheat husk.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a wheat peeling and grinding device, which includes an outer box body, an outer sand roller arranged on the inner wall of the outer box body, an inner sand roller placed in the outer box body and cooperating with the outer sand roller for grinding, and a driving member for driving the inner sand roller to rotate; the inner sand roller is supported by an "I"-shaped bracket, the bottom of the bracket is rotatably connected to the inner bottom of the outer box body, and the driving member extends from the feed port at the upper end of the outer box body and is coaxially connected to the bracket; the outer sand roller and the inner sand roller are both conical cylinder styles, and the taper of the outer sand roller is smaller than the taper of the inner sand roller, so that the distance between the outer sand roller and the inner sand roller gradually decreases from top to bottom; reinforcing ridges are provided on the inner wall of the outer sand roller and the inner wall of the outer sand roller, and the reinforcing ridges on the outer sand roller and the reinforcing ridges on the inner sand roller are staggered.

[0006] Preferably, the height of the reinforcing ridges is set between 1-2 mm.

[0007] Preferably, the distance between two adjacent reinforcing ridges is set between 5-10 mm.

[0008] Preferably, the bracket is connected to the outer box body via a star-shaped divergent connecting frame, a bearing assembly is provided at the upper end of the connecting frame, and is rotatably connected to the bracket via the bearing assembly.

[0009] Preferably, an arc-shaped guide plate is provided at the upper end of the bracket.

[0010] Preferably, the rotating shaft of the driving member is connected to the guide plate, and a protective sleeve is provided on the outer sleeve of the guide plate.

[0011] Preferably, the bottom of the outer box body adopts an arc-shaped bottom, and a discharge port is arranged at the lowest end of the arc-shaped bottom.

[0012] The beneficial effects of adopting the technical solution of the utility model are:

[0013] The utility model has different spacings between the inner and outer sand rollers, which gradually decrease from top to bottom. This allows the grinding force to gradually increase from top to bottom when grinding wheat, and the friction force on the outer skin of the wheat to gradually increase, so as to ensure the grinding and peeling effect of the outer skin of the wheat, and improve the quality and taste of the final flour ground. By setting the taper difference between the outer and inner sand rollers, the taper of the inner sand roller is greater than the taper of the outer sand roller, so as to achieve a gradual decrease in the spacing between the inner and outer sand rollers from top to bottom; by setting reinforced ridges on the inner wall of the outer sand roller and the outer wall of the inner sand roller, the reinforced ridges on the two are staggered, so that when grinding and peeling, the reinforced ridges can be used to grind the tail hair inside the tail end of the wheat and the bran at the belly groove, thereby improving the grinding effect.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The specific embodiments are as follows:

[0021] Embodiment 1, as Figure 1 , 2 As shown, a wheat peeling and grinding device comprises an outer box body 2, an outer emery roller 3, an inner emery roller 8, a driving member and a bracket 9. The bottom of the outer box body 2 is supported by legs. A funnel-shaped feed port 1 is provided at the top of the outer box body 2, and a discharge port 5 is provided at the bottom. The inner wall of the outer box body 2 is embedded with an outer emery roller 3. The inner emery roller 8 is placed in the outer box body 2 and is coaxially arranged with the outer emery roller 3 for grinding cooperation. The inner emery roller 8 is supported by an "I"-shaped bracket 9, the lower end of the bracket 9 is rotatably connected to the outer box body 2, the upper end of the bracket 9 is coaxially connected to the rotating shaft 11 of the driving member extending from the feed port 1, the driving member drives the bracket 9 and then drives the inner emery roller 8 to rotate, and the inner emery roller 8 and the outer emery roller 3 rotate relative to each other to achieve the grinding and peeling of wheat.

[0022] In this embodiment, the driving member adopts a servo motor 13, which runs smoothly without vibration.

[0023] The outer sand roller 3 and the inner sand roller 8 are both tapered to prevent the wheat from falling too fast and affecting the grinding effect. The tapers of the outer sand roller 3 and the inner sand roller 8 are different, and the spacing between them has been adjusted. In this embodiment, the taper of the inner sand roller 8 is slightly larger than the taper of the outer sand roller 3, which makes the spacing between the outer sand roller 3 and the inner sand roller 8 gradually decrease from top to bottom. In this way, when grinding wheat, as the grinding gap gradually decreases, the grinding force gradually increases, which is equivalent to grinding the wheat step by step to ensure that the required grinding effect is achieved.

[0024] The inner wall of the outer emery roller 3 and the outer wall of the inner emery roller 8 are both provided with reinforcing convex ridges 14, and the reinforcing convex ridges 14 on the two are arranged in a staggered manner. In this way, since there are tail hairs in the tail end of the endosperm of a single wheat, and there is also a ventral groove extending from the wheat head to the wheat tail on the surface of the small face, the tail hairs and the wheat bran at the ventral groove are not easy to be ground off, and the arrangement of the reinforcing convex ridges 14 can just strengthen the grinding, and better grind off the tail hairs and the wheat bran at the ventral groove.

[0025] Furthermore, the height of the reinforcing ribs 14 is set between 1-2 mm, and the spacing between two adjacent reinforcing ribs 14 is set between 5-10 mm. In this way, it is convenient to limit the wheat between the two reinforcing ribs 14 for grinding, and the reinforcing ribs 14 on the outer sand roller 3 and the inner sand roller 8 are arranged in a staggered manner. For the wheat placed between the two reinforcing ribs 14, the reinforcing ribs 14 on the opposite side are just convenient for grinding the tail hair and the belly groove of the wheat.

[0026] Furthermore, the bracket 9 and the outer box body 2 are connected by a connecting frame 7. The connecting frame 7 is a star-shaped divergent style, which improves the stability of the support of the bracket 9. A bearing assembly 6 is arranged at the upper end of the connecting frame 7, and the bracket 9 is connected to the bearing assembly 6 to ensure that the inner sand roller 8 can rotate relative to the outer box body 2.

[0027] Furthermore, an arc-shaped guide plate 10 is provided at the upper end of the bracket 9, and the rotating shaft 11 is connected to the top of the guide plate 10. When wheat is added to the outer box 2 from the feed port 1, the wheat flows downward along the guide plate 10 to avoid the wheat being retained on the top of the bracket 8.

[0028] Furthermore, a protective sleeve 12 is provided on the outer sleeve of the rotating shaft 11 of the servo motor 13. The protective sleeve 12 is fixed on the servo motor 13 to protect the rotating rotating shaft 11, thereby avoiding safety accidents caused by the rotation of the rotating shaft 11 during feeding, thereby improving safety.

[0029] Furthermore, the bottom of the outer box body 2 adopts an arc-shaped bottom 4 , and the discharge port 5 is set at the lowest end of the arc-shaped bottom 4 , so that the ground wheat is conveniently concentrated at the lowest point of the arc-shaped bottom 4 and discharged from the discharge port 5 .

[0030] When the wheat peeling and grinding device of the present embodiment is in use, wheat is fed from the feed port 1 into the outer box body 2, the wheat flows down along the guide plate 10 and enters the grinding space between the inner sand roller 8 and the outer sand roller 3, the servo motor 13 is turned on to drive the bracket 9 to rotate, the bracket 9 drives the inner sand roller 8 to rotate, and the inner sand roller 8 rotates relative to the outer sand roller 3 to achieve the grinding and peeling of the wheat, and grind off the wheat husk or tail hair. Since the grinding gap gradually becomes smaller from top to bottom, it is equivalent to grinding the wheat step by step, improving the grinding effect and grinding quality. The setting of the reinforced ridges 14 on the outer sand roller 3 and the inner sand roller 8 is convenient for limiting the position of the wheat, and for grinding the tail hair and belly groove of the wheat, further improving the grinding quality, and improving the quality and taste of the ground flour.

[0031] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
