Description

Technical Field

[0001] The invention relates to the technical field of grain milling equipment, and in particular to rice finishing equipment. Background Art

[0002] Rice is a major type of grain with high nutritional value. Before it can be eaten by people, it needs to be processed by grinding it into powder and then processing it into edible rice or noodles.

[0003] In the prior art, there is a Chinese invention patent with announcement number CN212702387U and patent name, which is a material crusher. It specifically discloses a frame, a grinding mill is arranged on the frame, a discharge pipe is arranged under the grinding mill, a screening cylinder is connected to the discharge pipe of the grinding mill, a cavity connected to the discharge pipe is opened in the screening cylinder, and a discharge pipe connected to the cavity is arranged below the screening cylinder; a clamping frame is fixedly connected to the cavity wall of the cavity, a screening assembly for screening materials is arranged in the clamping frame, a vibration motor is arranged on the clamping frame, a vibration assembly for cooperating with the vibration motor is arranged under the clamping frame, and a recovery assembly for recovering and re-crushing large particles on the screen is arranged on the side of the screening cylinder.

[0004] The above scheme has the advantage of reducing the occurrence of large and small particles being mixed together in the crushed rice.

[0005] However, in the actual rice processing process, the rice needs to be husked and then crushed, so different equipment is needed to realize husking and rice crushing respectively, so it is necessary to set up husking stations and rice crushing stations separately, and it is necessary to repeatedly realize the station transfer, resulting in low processing efficiency;

[0006] In addition, in the actual process of grinding rice into powder, broken rice often appears in the product due to the smooth surface of rice. In the prior art, broken rice and rice flour can only be distinguished by screening with sieves of different mesh sizes. Since the rice flour after grinding is easy to adhere together, the broken rice is more difficult to screen out. At the same time, the amount of rice flour is greater than that of broken rice, which increases the time required to screen out the broken rice, resulting in lower overall processing efficiency.

[0007] Therefore, a rice finishing device is proposed to solve the above-mentioned problems. Summary of the invention

[0008] Technical issues solved:

[0009] In view of the above-mentioned shortcomings of the prior art, the present invention provides a rice fine processing equipment, which can effectively solve the problem of low processing efficiency and poor effect of the rice processing equipment in the prior art.

[0010] Technical solution:

[0011] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0012] The present invention provides a rice fine processing device, comprising a machine body, wherein the upper end of the machine body is provided with two independent openings for respectively entering hulled rice and broken rice, and two matching shell grinding rollers are provided in the machine body and directly below the openings; wherein the outer ends of the two shell grinding rollers are respectively provided with matching tooth ends and smooth ends, and the tooth ends and the smooth ends are respectively located directly below the two openings, and a filter plate which can swing along the axial direction of the shell grinding roller is also provided at the lower end of the shell grinding roller, and the filter plate is provided with filter holes directly below the tooth ends and a filter groove directly below the smooth end.

[0013] Furthermore, a fan capable of supplying air toward one side of the filter tank is arranged in the body; wherein the cross section of the filter tank is in a trapezoidal shape that is wide at the top and narrow at the bottom, and the inclined surface of the filter tank faces one side of the fan.

[0014] Furthermore, it also includes a screening mechanism, which is arranged below the two crushing rollers, and includes an upper pressure plate and a lower pressure plate distributed up and down and parallel to the axis of the shell grinding roller, and the filter plate is arranged above the upper pressure plate; wherein, the lower end of the upper pressure plate is provided with a plurality of extrusion plugs with the plugs facing downward, and the lower pressure plate is provided with a plurality of slots along one side thereof, which respectively cooperate with the extrusion plugs, the upper pressure plate is movably mounted on the machine body and can move linearly along the setting direction of the slots, and the extrusion plugs and the slots are both provided with interconnected slot structures for the outflow of rice noodles.

[0015] Furthermore, a fixing frame which can move linearly along the setting direction of the slot is provided on the machine body, and the upper pressure plate is movably mounted on the fixing frame and can move elastically along its height direction; wherein, the filter plate is rotatably mounted on the fixing frame.

[0016] Furthermore, the filter plate is rotatably mounted on a fixing frame via a rotating shaft disposed in the middle of both sides thereof; an elliptical wheel is coaxially disposed on the outer side of the rotating shaft, and the elliptical wheel is always in contact with the upper end of the upper pressure plate.

[0017] Furthermore, the cross section of the extrusion plug is an isosceles trapezoidal structure that is wide at the top and narrow at the bottom, and the notch structures on the extrusion plug and the slot are both opened in the middle of the extrusion plug and the slot.

[0018] Furthermore, the lower pressing plate is provided with two movable frames which can move towards each other, and the movable frames are provided with a plurality of sliding blocks which are embedded in the slots.

[0019] Furthermore, the upper ends of the extrusion plugs are open, and an arch block is respectively arranged on the end surface of the upper pressing plate and between adjacent extrusion plugs.

[0020] Furthermore, a plurality of first grinding bars are obliquely arranged on both sides of the lower end of the extrusion plug, and second grinding bars matching with the first grinding bars are arranged in the slot.

[0021] Furthermore, the upper end of the sliding block is embedded in the bottom of the slot and the notch structure in the extrusion plug block.

[0022] Beneficial effects:

[0023] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0024] The present invention realizes the shell breaking function by arranging two openings, and arranging two smooth ends on the shell grinding rollers below the two openings, and realizes the shell breaking function by using meshing tooth ends, so that two functions are integrated on the same device, thereby improving the practicality of the device, and at the same time, after the shell is broken, the broken rice after the rice coat is removed can be quickly transferred through a rotatable filter plate, thereby improving the processing efficiency;

[0025] By arranging a filter plate under the crushing roller, coarser broken rice can be filtered in advance, and the preliminarily ground rice flour will pass through the filter plate and fall between the upper pressing plate and the lower pressing plate below it. By utilizing the extrusion plug provided at the lower end of the upper pressing plate and the slot that can cooperate with the extrusion plug at the upper end of the lower pressing plate, when the rice flour falls between the extrusion plug and the slot, the upper pressing plate can be moved to allow the rice flour to be ground again between the extrusion plug and the slot, thereby reducing the content of solid broken rice. At the same time, compared with the method of first grinding and then screening in traditional technology, the method of first screening and then grinding in this scheme can greatly reduce the amount of broken rice mixed in the rice flour.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] The present invention will be further described below in conjunction with the embodiments.

[0044] Example:

[0045] See attached Figure 1-11 , this embodiment proposes a rice processing equipment.

[0046] The processing equipment includes a machine body 1 and a screening mechanism. The upper end of the machine body 1 is provided with two independent openings 10 for hulled rice and broken rice respectively, and two matching hull grinding rollers 11 are provided in the machine body 1 and directly below the openings 10 .

[0047] In the present case, two openings 10 are provided and are independent of each other, and the outer ends of both sides of the shell grinding roller 11 are respectively provided with matching tooth ends and smooth ends, and the tooth ends and the smooth ends are respectively located directly below the two openings 10, and the tooth ends of the two shell grinding rollers 11 are meshed with each other, and the smooth ends of the two shell grinding rollers 11 are parallel and arranged at intervals. The smooth ends in the present case are made of rubber. When it is necessary to break the husk of the rice, the husk-bearing rice is put into the opening 10 located above the smooth end, and the rice husk is broken by squeezing the two shell grinding rollers 11. The rice after breaking the husk will form rice husks and broken rice. Similarly, when it is necessary to crush the husk-free rice and broken rice to form rice flour, the husk-free rice and broken rice are put into the opening 10 located above the tooth end.

[0048] A filter plate 21 which can swing along the axial direction of the shell grinding roller 11 is also provided at the lower end of the shell grinding roller 11. The filter plate 21 is provided with a filter hole 213 located just below the tooth end and a filter groove 214 located just below the smooth end.

[0049] When husking rice with husks, the husk rice is put into the opening 10 above the smooth end. At this time, the filter slot 214 on the filter plate 21 is tilted downward, and a fan 5 that can send air toward one side of the filter slot 214 is provided in the machine body 1. The rice husks and broken rice formed after breaking will be separated in the process of falling, and the rice husks are blown to a side away from the filter plate 21 by the fan 5. In this case, a first discharge port 12 for sending out the rice husks is provided on the side of the machine body 1 opposite to the fan 5.

[0050] The cross-section of the filter trough 214 is a trapezoidal shape that is wide at the top and narrow at the bottom, and the inclined surface of the filter trough 214 faces the side of the fan 5. The broken rice and / or shell-free rice will temporarily remain in the filter trough 214. When the shell is broken, the filter plate 21 rotates in the opposite direction to drive the inclined surface of the filter trough 214 to approach the horizontal or downward direction. The rice and broken rice will roll toward the side away from the first discharge port 12, and a second discharge port 13 is provided on the side corresponding to the machine body 1. The second discharge port 13 can be set to a container shape or a channel shape for collecting and storing broken rice and / or shell-free rice. When the broken rice and / or shell-free rice in the filter trough 214 completely falls into the second discharge port 13, the entire shell breaking operation is completed.

[0051] When the rice is crushed into powder, the broken rice and / or hull-free rice is initially ground by the tooth ends of the hull grinding roller 11, and the output is divided into two types: broken rice that is not completely crushed and rice powder.

[0052] In the present case, a screening mechanism is arranged below the two crushing rollers 11. First, the broken rice (the diameter of the broken rice is larger than the diameter of the filter hole 213) in the output can be screened out in advance through the filter holes 213 on the filter plate 21. The screening mechanism includes an upper pressing plate 2 and a lower pressing plate 3 which are distributed up and down and parallel to the axis of the shell grinding roller 11. The mesh size of the filter plate 21 can be set according to the diameter of the broken rice to ensure that the broken rice can be intercepted by the filter plate 21 during the falling process, while rice flour (regardless of coarseness) with a particle size smaller than the broken rice can pass through the filter plate 21 and enter the upper pressing plate 2.

[0053] Among them, the lower end of the upper pressing plate 2 is provided with a plurality of extrusion plugs 22 with the plugs facing downward, and the upper ends of the extrusion plugs 22 are open, that is, the upper end surface of the upper pressing plate 2 is provided with a plurality of rice noodle inlets formed by the upper end openings of the extrusion plugs 22, and the lower pressing plate 3 is provided with a plurality of slots 31 along one side thereof, which respectively cooperate with the extrusion plugs 22.

[0054] It is worth noting that in this case, the upper pressure plate 2 can move up and down toward one side of the lower pressure plate 3, and can also move linearly along the setting direction of the slot 31, that is, reciprocate in the horizontal direction of the body 1 (in this case, the width direction of the body 1).

[0055] Since broken rice inevitably exists in the rice flour mixture which leaks out from the filter plate 21, when the rice flour mixture with broken rice falls onto the upper pressing plate 2, it will first enter the slot 31 of the lower pressing plate 3 from the upper end opening of the extrusion plug 22. The rice flour mixture in the slot 31 can be further ground by the downward pressure of the upper pressing plate 2 and the linear displacement of the entire screening mechanism. The extrusion plug 22 and the slot 31 are both provided with interconnected slot structures for the rice flour to flow out, and the ground rice flour will precipitate out through the slot structure in the slot 31.

[0056] It should be noted that in order to prevent the rice noodle mixture filtered out of the filter plate 21 from accurately entering the slot structure in the extrusion plug 22, in the present case, an arch block 23 is provided on the end surface of the upper pressing plate 2 and between adjacent extrusion plugs 22, and an arc block bent toward the middle part of the upper pressing plate 2 is provided on both sides of the upper end of the upper pressing plate 2 to prevent the rice noodle mixture from staying in the space between adjacent extrusion plugs 22.

[0057] Specifically, it should be noted that in the present case, a fixing frame 4 is provided on the machine body 1 and can move linearly along the setting direction of the slot 31 (i.e., the width direction of the machine body 1). The driving method of the fixing frame 4 is not limited here, and can be driven by any one of a screw rod, a reciprocating motor, and an electric push rod.

[0058] The fixing frame 4 includes four vertically arranged support rods 41, each of which has a slide groove 411 along its height direction, and both sides of the upper pressure plate 2 have a sliding portion 24 inserted into the adjacent slide grooves 411, and each slide groove 411 has a spring 412, which abuts against the lower end of the sliding portion 24, so that the upper pressure plate 2 is movably mounted on the fixing frame 4 and can be elastically moved along its height direction.

[0059] The lower pressing plate 3 is fixed on the fixing frame 4 and moves synchronously with the linear movement of the fixing frame 4 .

[0060] When the filter plate 21 is in a normal filtering state, the filter plate 21 is parallel to the upper pressure plate 2, that is, the rice flour mixture falling from the shell grinding roller 11 will fall into the upper end of the filter plate 21. At this time, the fixed frame 4 is driven to move back and forth, allowing the filter plate 21 to move left and right synchronously, and the rice flour mixture at the upper end of the filter plate 21 is screened.

[0061] In order to improve the screening effect, the filter plate 21 in this case is rotatably mounted on the fixed frame 4, that is, by allowing the filter plate 21 to have a certain slope, the heavier broken rice is easier to precipitate from the mixture and roll off the filter plate 21 into the second discharge port 13, thereby improving the screening effect of the rice flour mixture to a certain extent.

[0062] When the amount of the rice flour mixture in the slot 31 reaches a certain standard or the shell grinding roller 11 has been working for a period of time, the filter plate 21 will start to rotate. In this case, the maximum rotation angle of the filter plate 21 is 30 degrees. At this time, the rice flour falling through the filter hole 213 is ground more finely.

[0063] The filter plate 21 is rotatably mounted on the fixed frame 4 via a rotating shaft 211 arranged in the middle of both sides thereof, and the two crushing rollers 11 are both located on one side of the rotating shaft 211 of the filter plate 21. It should be noted that when the filter plate 21 rotates, the distance between the upper pressing plate 2 and the lower pressing plate 3 will be shortened, that is, the extrusion plug 22 will be inserted into the slot 31. At this time, the fixed frame 4 still drives the upper pressing plate 2 to move back and forth to grind the rice flour mixture in the slot 31.

[0064] It is worth mentioning that in order to improve the grinding effect, in this case, a plurality of first grinding bars 221 are obliquely arranged on both sides of the lower end of the extrusion plug 22. The obliquely arranged grinding bars 221 can reduce the adhesion of the rice flour mixture. At the same time, compared with the straight horizontal arrangement, the extrusion area between the obliquely arranged first grinding bars 221 and the rice flour mixture is larger, and the shell grinding effect is better. A second grinding bar 311 is arranged in the slot 31 and on the moving path of the first grinding bar 221. The second grinding bar 311 cooperates with the first grinding bar 221 to extrude the material between the two grinding bars under the downward extrusion of the first grinding bar 221. The arrangement of the second grinding bar 311 is not limited. It can be arranged in parallel with the side wall of the extrusion plug 22, or it can extend linearly along the length direction of the slot 31. It will not be described one by one here, and it is not shown in the drawings.

[0065] In the present case, an elliptical wheel 212 is coaxially arranged on the outer side of the rotating shaft 211, and one of the rotating shafts 211 is driven to rotate by a motor. When the elliptical wheel 212 starts to rotate, due to its elliptical characteristics, it can gradually increase / decrease the pressure on the upper pressure plate 2 as it rotates, thereby realizing the up and down movement of the upper pressure plate 2.

[0066] In the present case, the elliptical wheel 212 is always in conflict with the upper end of the upper pressure plate 2. When no downward pressure is applied to the upper pressure plate 2, the angle between the long diameter of the elliptical wheel 212 and the upper end plane of the upper pressure plate 2 is 60 degrees. When the elliptical wheel 212 starts to rotate and reaches the maximum rotation angle, the long diameter of the elliptical wheel 212 is perpendicular to the upper end plane of the upper pressure plate 2.

[0067] It is worth noting that in this case, the length and / or width of the filter plate 21 is greater than the length and / or width of the two shell grinding rollers 11, ensuring that the rice flour mixture ground by the shell grinding rollers 11 can be located above the filter plate 21 after rotation, and the rice flour is gradually precipitated from top to bottom.

[0068] The cross-sections of the extrusion plug 22 and the slot 31 are both isosceles trapezoidal structures that are wide at the top and narrow at the bottom. The notch structures on the extrusion plug 22 and the slot 31 are both opened in the middle of the extrusion plug 22 and the slot 31, so that when the extrusion plug 22 is pressed down, the opposite surfaces of the extrusion plug 22 and the slot 31 will first complete an extrusion. At the same time, the extrusion plug 22 will also move linearly, and further extrude through friction, thereby improving the grinding effect of the broken rice.

[0069] Due to the easy adhesion of rice noodles, in order to prevent the ground rice noodles from adhering to the inner wall of the slot 31, in this case, two movable frames 32 that can move in opposite directions are provided on the lower pressing plate 3. The driving method of the movable frames 32 is not specifically limited. It can be driven by a screw (both ends have threads and rotate in opposite directions, and the movable frames 32 and the screw threads cooperate), or by an electric push rod (both movable frames 32 are driven by the electric push rod). The movable frames 32 are provided with a plurality of sliders 321 embedded in the slot 31. When the extrusion block 22 in the upper pressing plate 2 is not inserted into the slot 31, the sliders 321 in the movable frames 32 can be linearly displaced in the slot 31 to rub the two side end walls inside the slot 31 to prevent the rice noodles from adhering. During processing, the two movable frames 32 will be symmetrically distributed with the upper pressing plate 2 as the center.

[0070] Optionally, the upper ends of the sliders 321 on the two movable frames 32 in the present case can also be embedded in the bottom of the slot 31 and the notch structure in the extrusion block 22, that is, the movement of the movable frame 32 is no longer limited by the positions of the upper and lower pressure plates. First, in this manner, the upper end of the slider 321 is in the shape of an isosceles triangle. When the upper pressure plate 2 is pressed downward, the slider 321 is already located in the slot 31, and the notch structure at the bottom of the extrusion block 22 will directly fit over the top position of the slider 321 during the downward movement. When the slider 321 is displaced synchronously with the movement of the movable frame 32, the rice noodles attached to the slot 31 and the side wall of the extrusion block 22 will be scraped off.

[0071] A third discharge port 14 for the rice noodles to flow out smoothly is arranged on the machine body 1 , and the third discharge port 14 is arranged below the notch structure on the slot 31 .

[0072] The reciprocating motion of the fixing frame 4 also has a positive auxiliary effect on breaking the husks, that is, when separating the rice husks from the broken rice, the reciprocating swing of the fixing frame 4 can make the rice husks integrated into the broken rice more easily carried away by the wind provided by the fan 5.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
