Description

Technical Field

[0001] The invention belongs to the technical field of grain processing equipment, and in particular relates to a hulling device for hulled grains. Background Art

[0002] The background information related to the present invention provided in this section may not all be prior art, and may contain content that does not constitute prior art.

[0003] A rice husker is a commonly used grain processing equipment for grain processing. Existing rice husker uses a pair of rolling rollers with different linear speeds to remove the husk of rice.

[0004] However, grains with smaller grain volumes than rice (also known as small grains), such as but not limited to millet (also known as "millet") and sorghum, have a low hulling rate when using existing rice hullers.

[0005] In order to solve the above problems, there are currently two methods for shelling the small grains.

[0006] That is, one hulling operation method is that after the small grains have been hulled once by an existing rice huller, the residues received at the output end of the rice huller (i.e. a mixture of grains with hulls removed and grains with hulls not removed) are transported back to the input end (i.e. the feed port) of the rice huller manually or mechanically, so that the small grains can be hulled for a second time by the same existing rice huller.

[0007] Another shelling operation method is to connect two existing rice hullers through a closed pipe and a suction device (such as a fan, etc.), one end of the closed pipe is used to close the output end of one existing rice huller, and the other end is used to close the input end of the other existing rice huller.

[0008] The above-mentioned shelling operation requires the pair of rollers to roll back and forth twice to achieve an acceptable shelling rate, which increases the workload of the pair of rollers. In order to achieve an acceptable shelling rate, the working time of the existing rice husking machine must be at least doubled. When the loss rate of the pair of rollers is the same, the number of grains with an acceptable shelling rate will be at least halved. In addition, when the residue output from the output end of the existing rice husking machine is manually lifted to the input end (i.e., the feed port) of the existing rice husking machine located at a relatively upper position, it will obviously greatly increase the workload of the operator.

[0009] Although the above-mentioned another shelling operation can solve the problems existing in the pair of crushing rollers in the above-mentioned shelling operation, since the price of an existing rice husker is at least tens of thousands, this will inevitably increase the cost of production materials required for the shelling operation; moreover, the additional existing rice husker will also increase the requirement for installation space, which is especially true for the situation where the installation space is very limited, so that the installation environment of the other shelling operation will be subject to certain restrictions; in addition, it is also necessary to pay the cost of the relevant pipelines and suction equipment (such as fans, etc.) required to connect the two existing rice husker and the space required for installation. Summary of the invention

[0010] The purpose of the present invention is to propose a rice husker, which realizes step-by-step rolling by installing two sets of rolling components in the casing of a rice husker, so as to solve the problem of relatively low efficiency in husking small grains without basically increasing the working time and the related pipelines and suction equipment (such as fans, etc.) and the required space required for connecting the two existing rice husker.

[0011] Based on the above purpose, the present invention proposes a rice husker, which is provided with a feeding area, a rice husking area and a separation area in sequence according to a working direction, and the rice husker comprises:

[0012] The driving assembly for rolling includes:

[0013] A roller drive, at least one;

[0014] The first rolling assembly is arranged on the rice husking area and cooperates with the rolling driving assembly to roll the grains from the feeding area during operation, and includes:

[0015] The first rotating rolling element has a substantially circular cross section and rotates at a first linear speed during operation; and

[0016] The first second rotary rolling element has a substantially circular cross section and cooperates with the first rotary rolling element to rotate at a first second linear speed during operation;

[0017] The directions of the first linear velocity and the second linear velocity are opposite and different in magnitude. When working, the grains from the feeding area enter from the relatively upper area between the first rotating rolling element and the second rotating rolling element, and exit from the relatively lower area between the first rotating rolling element and the second rotating rolling element, thereby rolling the grains from the feeding area for the first time.

[0018] The rear rolling assembly is arranged on the rice husking area and cooperates with the rolling driving assembly. When working, it is used to roll the grains that have been rolled for the first time from the relatively lower area between the first rotating rolling element and the second rotating rolling element to achieve the second rolling, including:

[0019] The first rear rotary rolling element has a substantially circular cross section and rotates at a first rear linear speed during operation; and

[0020] The second rear rotary rolling member has a substantially circular cross section and cooperates with the first rear rotary rolling member to rotate at a second rear linear speed during operation;

[0021] Wherein, the directions of the first and second linear speeds are opposite to each other and the magnitudes are different, and during operation, the grains that have been rolled for the first time and come out from the relatively lower area between the first and second rotating rolling parts of the preceding rotation enter from the relatively upper area between the first and second rotating rolling parts of the preceding rotation, and exit from the relatively lower area between the first and second rotating rolling parts of the preceding rotation, so as to realize the second rolling; and

[0022] The separator is arranged in the separation area and is used for separating the husks in a detached state from the grains from the husking area.

[0023] In one example, the operating power required to drive the leading rolling assembly is greater than the operating power required to drive the trailing rolling assembly.

[0024] In one example, the number of the rolling drivers is multiple, at least one of which is directly or indirectly drivingly matched with the preceding rolling component, and at least another one is drivingly matched with the following rolling component;

[0025] Among them, the sum of the working powers of all the rolling drivers that cooperate with the driving of the preceding rolling assembly is 1 to 1.5 times the sum of the working powers of all the rolling drivers that cooperate with the driving of the succeeding rolling assembly.

[0026] In one example, the number of the rolling driver is single, and it is directly or indirectly driven and cooperated with the preceding rolling component and the following rolling component at the same time;

[0027] The working power output by the rolling driver to drive the preceding rolling component is 1 to 1.5 times the working power output by the driver to drive the succeeding rolling component.

[0028] In one example, it also includes:

[0029] At least one guide member is arranged between the relatively lower area between the preceding first rotating rolling member and the preceding second rotating rolling member and the relatively upper area between the following first rotating rolling member and the following second rotating rolling member, and when in operation, is used to guide the grains that have been rolled for the first time and come out from the relatively lower area between the preceding first rotating rolling member and the preceding second rotating rolling member to the relatively upper area between the following first rotating rolling member and the following second rotating rolling member.

[0030] In one example, a prior distance adjustment component is also included, which cooperates with the prior first rotating rolling component or the prior second rotating rolling component, and the prior distance adjustment component includes:

[0031] The first distance adjustment rotating arm is provided for the first first rotating rolling member or the second first rotating rolling member; and

[0032] The driver for prior distance adjustment cooperates with the prior distance adjustment rotating arm and is used to drive the prior distance adjustment rotating arm to rotate and move so as to adjust the distance between a prior rotational rolling component arranged on the prior distance adjustment rotating arm and another prior rotational rolling component which is not arranged on the prior distance adjustment rotating arm and is fixed in position and cooperates with the prior rotational rolling component for rolling.

[0033] In one example, it also includes a rear distance adjustment component, which cooperates with the rear first rotating rolling member or the rear second rotating rolling member, and the rear distance adjustment component includes:

[0034] A rear distance adjustment rotating arm is provided for the rear first rotating rolling member or the rear second rotating rolling member; and

[0035] The rear distance adjustment driver cooperates with the rear distance adjustment rotating arm and is used to drive the rear distance adjustment rotating arm to rotate and move so as to adjust the distance between a rear rotational rolling member arranged on the rear distance adjustment rotating arm and another rear rotational rolling member which cooperates with the rear distance adjustment rotating arm, is not arranged on the rear distance adjustment rotating arm and is fixed in position.

[0036] In one example, a prior manual operation component and a subsequent manual operation component are also included;

[0037] The prior manual operation components include:

[0038] A previous manual operation port is provided corresponding to the previous rolling assembly; and

[0039] A first manual operation door is hinged to the first manual operation opening and can be opened and closed on the first manual operation opening;

[0040] The post-manual operation component includes:

[0041] A rear manual operation port is provided corresponding to the rear rolling assembly; and

[0042] The rear manual operation door is hinged on the rear manual operation opening and can be opened and closed on the rear manual operation opening.

[0043] In one example, the prior manual operation assembly further includes a prior manual observation window provided on the prior manual operation door;

[0044] The rear manual operation component also includes a rear manual observation window, which is arranged on the rear manual operation door.

[0056] The present invention will be described below with reference to several examples. It should be understood that these embodiments are described to enable those skilled in the art to better understand and implement the present invention, and do not represent or imply any limitation on the scope of the present invention.

[0057] Grain must have lemma. It is the general name for all kinds of grains and food crops.

[0058] Gu, from He and from Husk, the husk is the hard outer skin wrapped around the outside.

[0059] In ancient China, there was already a term for "five grains", which referred to hemp, millet, sorghum, wheat and beans. Nowadays, there are more types of grains.

[0060] Rice is the main grain in southern China, while wheat is the main grain in northern China. The grain sizes of the two are similar. The existing rice hullers can automatically hull the rice and wheat, and the hulling rate is also good.

[0061] As people's living standards improve, their requirements for food nutrition increase. They not only want to eat enough, but also want to eat nutritiously.

[0062] Among them, the high nutritional value of millet has been discovered and is very popular among consumers.

[0063] The millet here actually includes large yellow rice and small yellow rice. Large yellow rice is processed from glutinous millet (ancient name millet), while small yellow rice is a northern rice processed from millet (ancient name millet).

[0064] Both large yellow rice and small yellow rice are often used for making soups and desserts, but large yellow rice is more suitable for making traditional northern foods such as rice cakes and bean buns, while small yellow rice is often used for cooking rice.

[0065] In addition, Xiaomi currently also includes black Xiaomi and others.

[0066] Due to the increasing demand for this millet, the cultivated area and output of this millet have also shown explosive growth.

[0067] Since millet is covered with a hard outer skin (i.e., shell), it needs to be shelled after harvesting.

[0068] The grains of millet are much smaller than those of rice and wheat, and generally occupy only half the volume of the rice and wheat or less.

[0069] However, in the prior art, there is no equipment specifically for shelling small grains such as millet, and the shelling can only be done by using a rice husking machine specifically for shelling relatively large grains such as rice or wheat. The common operation or structure of the rice husking machine is as follows.

[0070] A rice husker is a machine that mechanically hulls relatively large grains such as rice or wheat. It usually includes a feeding area, a husking area, and a separation area. The feeding area is the area where the grains enter; the husking area is the grain husking area; and the separation area is the area where the husks that have been detached from the grains are separated from the parts that were originally wrapped by the husks.

[0071] A hulling operation method is that after the small grains have been hulled once by an existing rice huller, the residues received at the output end of the rice huller (i.e., a mixture of grains with hulls removed and grains with hulls not removed) are transported back to the input end (i.e., the feed port) of the rice huller manually or mechanically, so that the small grains can be hulled for a second time by the same existing rice huller.

[0072] Another shelling operation method is to connect two existing rice hullers through a closed pipe and a suction device (such as a fan, etc.), one end of the closed pipe is used to close the output end of one existing rice huller, and the other end is used to close the input end of the other existing rice huller.

[0073] The above-mentioned shelling operation requires the pair of rollers to roll back and forth twice to achieve an acceptable shelling rate, which increases the workload of the pair of rollers. In order to achieve an acceptable shelling rate, the working time of the existing rice husking machine must be at least doubled. When the loss rate of the pair of rollers is the same, the number of grains with an acceptable shelling rate will be at least halved. In addition, when the residue output from the output end of the existing rice husking machine is manually lifted to the input end (i.e., the feed port) of the existing rice husking machine located at a relatively upper position, it will obviously greatly increase the workload of the operator.

[0074] Although the above-mentioned another shelling operation can solve the problems existing in the pair of crushing rollers in the above-mentioned shelling operation, since the price of an existing rice husker is at least tens of thousands, this will inevitably increase the cost of production materials required for the shelling operation; moreover, the additional existing rice husker will also increase the requirement for installation space, which is especially true for the situation where the installation space is very limited, so that the installation environment of the other shelling operation will be subject to certain restrictions; in addition, it is also necessary to pay the cost of the relevant pipelines and suction equipment (such as fans, etc.) required to connect the two existing rice husker and the space required for installation.

[0075] In order to solve the above-mentioned possible problems, one embodiment of the present invention is a complete structure, including a casing 1, which can be divided into a feeding area a, a hulling area b and a separation area c from the upper part to the lower part of the casing 1, and also includes a rolling drive assembly, a first rolling assembly, a rear rolling assembly, and a separator.

[0076] It should be noted that the feeding area a, the husking area b and the separation area c in one embodiment of the present invention can be three independent parts, which can be combined when used. Such a design is convenient for the individual replacement of product components. In addition, each independent part can be transported separately to reduce the complexity of transportation. Each part can also be sold separately, which is conducive to consumers to purchase in a relatively economical way.

[0077] The working principle is that, with the driving force provided by the rolling drive assembly, the grains to be husked, which are smaller in volume than rice, wheat, etc., enter the first rolling assembly driven by the rolling drive assembly to receive the first rolling, and then directly enter the second rolling assembly driven by the rolling drive assembly for the second rolling. The first rolling assembly and the second rolling assembly are located in the same rice husking area. After the second rolling, the grains enter the separator to automatically separate the shell of the grains that are in a detached state in the grains after the second rolling from the part of the grains that was originally wrapped by the shell.

[0078] In addition, it should be noted that after the first rolling, the grains coming out of the previous rolling assembly include grains with husks, grains without husks, and husks that have been detached, which means that the number of grains that need to be dehusked is greatly reduced.

[0079] In addition, even these grains with husks may be divided into grains that are completely tightly wrapped by the husks, and grains in which a part of the husk is tightly wrapped and another part is separated from the wrapped part, or even if it is not separated, the tightness of the other part of the husk with the wrapped part is reduced. Moreover, after the first rolling, part of the heat generated by the friction when the grain is rolled by the first rolling component is absorbed by the grain, which may cause the temperature of the grain to rise. Since the husk in the grain and the part wrapped by the grain are different materials, their thermal expansion coefficients are different. In the subsequent second rolling by the subsequent rolling component, it may no longer be necessary to apply the same rotational force as in the first rolling. In this way, it may eventually happen that the power required to drive the subsequent rolling component may be less than the power required to drive the first rolling component.

[0080] The power required to drive the second rolling may be reduced. Therefore, when selecting a driving component for rolling, it is not necessary to choose a model with a rated power twice that of the power required to drive the first rolling component, but a model with a relatively smaller rated power.

[0081] As is known to all, the volume, weight, material consumption, etc. of the rolling drive assembly with a relatively high rated power are larger than those of the rolling drive assembly with a relatively low rated power, and are usually not at the same order of magnitude. Therefore, in addition to being economically advantageous, choosing the rolling drive assembly with a relatively low rated power is more importantly advantageous in terms of installation space requirements, the supporting structure and materials supporting the rolling drive assembly, and the overall product layout.

[0082] As an example of the working power required to drive the first rolling component and the second rolling component, the working power required to drive the first rolling component is 1 to 1.5 times the working power required to drive the second rolling component, and optionally 1.1, 1.2, 1.3, 1.4 times, that is, the values ​​of the working power of the two can be different, and do not need to be the same, so that unnecessary power output can be avoided. Of course, if the ratio of the working power is too large, that is, the working power required by the second rolling component is lower than a minimum working power threshold, it will affect its shelling rate. Of course, if the ratio of the working power is close to 1, it will cause the rated power of the selected driver to be larger than the actual working power, and it cannot fully play its role.

[0083] As an example, in the existing another type of equipment for small grain shelling operation, when two rice hullers with the same rated power are combined for millet shelling, when both use a 12-inch rolling length, the two hullers are equipped with a drive motor with a rated power of 11KW. In actual use, the working power required by the first huller specifically for rice or wheat shelling is usually 11KW, and the working power required by the second huller specifically for rice or wheat shelling is only 7.5KW, which is 11KW / 7.5KW=1.47 times. This results in the drive motor in the second huller specifically for rice or wheat shelling not fully exerting the size set by its rated power, resulting in the equipment being overqualified. The rolling drive assembly in the embodiment of the present invention can select a rolling drive assembly with a rated power of appropriate size according to the actual conditions of the working power required by the preceding rolling assembly and the working power required by the succeeding rolling assembly, without the need to select a relatively large driving motor with a rated power exceeding the above-mentioned working power.

[0084] Rolling drive components

[0085] The rolling drive assembly is used to drive the first rolling assembly and the second rolling assembly, and comprises a rolling driver. The rolling driver drives the first rolling assembly and the second rolling assembly to perform rotational motion to achieve the purpose of rolling the grains.

[0086] The number of the rolling drivers can be one or more, which can be set according to needs.

[0087] In one example, the rolling driver may be a motor structure, and the motor may be a variable frequency motor, which realizes speed change by motor frequency change, or a fixed frequency motor. In this case, the fixed frequency motor can be connected to a transmission to realize speed change. In another example, the rolling driver is a combination of a cylinder and a rotary transmission component. The rotary transmission component may include a push rod and a rotating wheel connected thereto, and the push rod is connected to the movable end of the cylinder, and the rotating wheel is directly or indirectly connected to the preceding rolling component and the following rolling component), so as to realize rotational motion.

[0088] First roll the components

[0089] The first rolling assembly is arranged on the husking area and cooperates with the rolling drive assembly. When working, it is used to roll the grains from the feeding area. It includes a first rotating rolling member and a second rotating rolling member, which are arranged close to each other (that is, the distance between them is usually basically zero).

[0090] Since the first preceding rotating rolling member and the second preceding rotating rolling member are rotationally matched to achieve rotating rolling, the cross-sections of the two rotating rolling members are substantially circular.

[0091] During operation, the first rotating rolling element rotates at a first linear velocity, and the second rotating rolling element rotates at a second linear velocity. The directions of the first linear velocity and the second linear velocity are opposite and different in magnitude. During operation, the grains from the feeding area enter from the relatively upper area between the first rotating rolling element and the second rotating rolling element, and exit from the relatively lower area between the first rotating rolling element and the second rotating rolling element, thereby rolling the grains from the feeding area for the first time.

[0092] Rolling components at the rear

[0093] The rear rolling assembly is arranged on the rice husking area and cooperates with the rolling driving assembly. When working, it is used to roll the grains that have been rolled for the first time from the relatively lower area between the rotating first rotating rolling member and the first second rotating rolling member. The rear first rotating rolling member and the rear second rotating rolling member are arranged close to each other (that is, the distance between the two is usually basically zero).

[0094] Since the first rear rotary rolling member and the second rear rotary rolling member are rotationally matched to achieve rotary rolling, the cross-sections of the two rotary rolling members are substantially circular.

[0095] During operation, the first rear rotating rolling member rotates at a first rear linear speed, and the second rear rotating rolling member rotates at a second rear linear speed. The directions of the first rear linear speed and the second rear linear speed are opposite and different in magnitude. During operation, the grains that have been rolled for the first time come out from the relatively lower area between the first rotating preceding rolling member and the second rotating rolling member, enter from the relatively upper area between the first rotating preceding rolling member and the second rotating rolling member, and exit from the relatively lower area between the first rotating preceding rolling member and the second rotating rolling member, so as to realize the second rolling.

[0096] Separator

[0097] The separator is arranged in the separation area and is used for separating the husks in a detached state from the grains from the husking area.

[0098] The separator comprises a separation fan, which utilizes the difference in specific gravity between husks on grains and the part wrapped by the husks, and separates the husks from the part wrapped by the husks through wind blown by the separation fan.

[0099] An example of an embodiment of the present invention is as follows Figures 1 to 8 As shown, it includes a rolling drive motor 101 (a structure of the rolling drive), a belt transmission assembly 210 (a structure of the rolling transmission assembly), a first rotating rolling shaft 311 and a coaxial first rotating rolling rubber roller 312 (a structure of the first rotating rolling part), a second rotating rolling shaft 321 and a coaxial first rotating rolling rubber roller 322 (a structure of the second rotating rolling part), a first rotating rolling shaft 411 and a coaxial first rotating rolling rubber roller 412 (a structure of the first rotating rolling part), a second rotating rolling shaft 421 and a coaxial second rotating rolling rubber roller 422 (a structure of the second rotating rolling part).

[0100] like Figures 3 to 8 As shown, the belt transmission assembly 210 includes a first preceding pulley 211, a second preceding pulley 212, a first following pulley 213, a second following pulley 214 and a closed rolling transmission belt 215. The first preceding pulley 211 and the first preceding rotating rolling rubber roller 312 are coaxially arranged on the first preceding rotating rolling shaft 311. The second preceding pulley 212 and the second preceding rotating rolling rubber roller 322 are coaxially arranged on the second preceding rotating rolling shaft 321. The first following pulley 213 and the first following rotating rolling rubber roller 412 are coaxially arranged on the first following rotating rolling shaft 411. The second following pulley 214 and the second following rotating rolling rubber roller 422 are coaxially arranged on the second following rotating rolling shaft 421.

[0101] The rolling transmission belt 215 cooperates with the first leading pulley 211, the second leading pulley 212, the first trailing pulley 213 and the second trailing pulley 214 at the same time, that is, the rolling transmission belt 215, under the direct or indirect drive of the rolling drive motor 101, drives the first leading pulley 211, the second leading pulley 212, the first trailing pulley 213 and the second trailing pulley 214 to rotate at the same time.

[0102] During operation, the rotation linear speeds of the first preceding pulley 211, the second preceding pulley 212, the first following pulley 213 and the second following pulley 214 are the same. The rotation angular speeds of the first preceding pulley 211, the second preceding pulley 212, the first following pulley 213 and the second following pulley 214 can be controlled by selecting the first preceding pulley 211, the second preceding pulley 212, the first following pulley 213 and the second following pulley 214 of different radii; so that the rotation angular speeds of the first preceding rotating rolling rubber roller 312, the second preceding rotating rolling rubber roller 322, the first following rotating rolling rubber roller 412 and the second following rotating rolling rubber roller 422, which are coaxial with the first preceding pulley 211, the second preceding pulley 212, the first following pulley 213 and the second following pulley 214 respectively, are different.

[0103] Normally, the cross-sections of all the above-mentioned rotating rolling rubber rollers are basically circular (or may be other shapes), and their maximum radii are basically the same, so that the rotational linear speeds of all the rotating rolling rubber rollers can be different, so that a linear speed difference is maintained between the first rotating rolling rubber roller 312 and the second rotating rolling rubber roller 322, and another linear speed difference is maintained between the first rotating rolling rubber roller 412 and the second rotating rolling rubber roller 422, so as to achieve the purpose of rolling and shelling the grains.

[0104] Another example of an embodiment of the present invention includes two rolling drive motors (a structure of the rolling drive), a belt transmission assembly (a structure of the rolling transmission assembly), a first leading rotating rolling shaft and a coaxial first leading rotating rolling rubber roller (a structure of the first leading rotating rolling part), a second leading rotating rolling shaft and a coaxial second leading rotating rolling rubber roller (a structure of the second leading rotating rolling part), a first trailing rotating rolling shaft and a coaxial first trailing rotating rolling rubber roller (a structure of the first trailing rotating rolling part), a second trailing rotating rolling shaft and a coaxial second trailing rotating rolling rubber roller (a structure of the second trailing rotating rolling part).

[0105] The belt transmission assembly includes a first preceding pulley, a second preceding pulley, a first following pulley, a second following pulley and two closed rolling transmission belts. The first preceding pulley and the first preceding rotating rolling rubber roller are coaxially arranged on the first preceding rotating rolling shaft. The second preceding pulley and the second preceding rotating rolling rubber roller are coaxially arranged on the second preceding rotating rolling shaft. The first following pulley and the first following rotating rolling rubber roller are coaxially arranged on the first following rotating rolling shaft. The second following pulley and the second following rotating rolling rubber roller are coaxially arranged on the second following rotating rolling shaft.

[0106] One of the rolling transmission belts cooperates with the first preceding pulley and the second preceding pulley at the same time, that is, the rolling transmission belt is driven directly or indirectly by a rolling drive motor to simultaneously drive the first preceding pulley and the second preceding pulley to rotate.

[0107] Another of the rolling transmission belts cooperates with the first rear pulley and the second rear pulley at the same time, that is, the other rolling transmission belt drives the first rear pulley and the second rear pulley to rotate at the same time under the direct or indirect drive of another rolling drive motor.

[0108] During operation, the rotational linear speeds of the first prior pulley and the second prior pulley are the same, and the rotational angular speeds of the first prior pulley and the second prior pulley can be controlled by selecting the first prior pulley and the second prior pulley with different radii; so that the rotational angular speeds of the first prior rotating type rolling rubber roller and the second prior rotating type rolling rubber roller, which are coaxial with the first prior pulley and the second prior pulley respectively, are different.

[0109] The rotational linear velocities of the first rear pulley and the second rear pulley are the same, and the rotational angular velocities of the first rear pulley and the second rear pulley can be controlled by selecting the first rear pulley and the second rear pulley with different radii; so that the rotational angular velocities of the first rear rotating rolling rubber roller and the second rear rotating rolling rubber roller, which are coaxial with the first rear pulley and the second rear pulley respectively, are different.

[0110] Normally, the radii of the cross-sections of all the above-mentioned rotating rolling rubber rollers are basically the same, so that the rotational linear speeds of all the rotating rolling rubber rollers can be different, so that a linear speed difference is maintained between the first rotating rolling rubber roller and the second rotating rolling rubber roller, and another linear speed difference is maintained between the first rotating rolling rubber roller and the second rotating rolling rubber roller, so as to achieve the purpose of rolling and shelling the grains.

[0111] At this time, due to the setting of two rolling drive motors, when selecting the model of the rolling drive motor that drives the rear rolling assembly, a model with a rated power smaller than the rated power of the rolling drive motor that drives the front rolling assembly can be selected. This is not only more economical than two rolling drive motors with the same rated power (the rated power is the rated power of the one with the largest rated power of the two motors), but also can be optimized in terms of its weight, volume, structure, material and other aspects.

[0112] Another example of an embodiment of the present invention includes four rolling drive motors (a structure of the rolling drive), a first leading rotating rolling shaft and a coaxial first leading rotating rolling rubber roller (a structure of the first leading rotating rolling part), a second leading rotating rolling shaft and a coaxial second leading rotating rolling rubber roller (a structure of the second leading rotating rolling part), a first trailing rotating rolling shaft and a coaxial first trailing rotating rolling rubber roller (a structure of the first trailing rotating rolling part), a second trailing rotating rolling shaft and a coaxial second trailing rotating rolling rubber roller (a structure of the second trailing rotating rolling part).

[0113] The four rolling drive motors are directly or indirectly driven and cooperated with a first rotating rolling shaft, a second rotating rolling shaft, a first rotating rolling shaft and a second rotating rolling shaft.

[0114] During operation, the four rolling driving motors independently control the rotational angular velocity of the first rotating rolling rubber roller, the preceding second rotating rolling rubber roller, the following first rotating rolling rubber roller and the following second rotating rolling rubber roller corresponding thereto.

[0115] Normally, the radii of the cross-sections of all the above-mentioned rotating rolling rubber rollers are basically the same, so that the rotational linear speeds of all the rotating rolling rubber rollers can be different, so that a linear speed difference is maintained between the first rotating rolling rubber roller and the second rotating rolling rubber roller, and another linear speed difference is maintained between the first rotating rolling rubber roller and the second rotating rolling rubber roller, so as to achieve the purpose of rolling and shelling the grains.

[0116] At this time, due to the setting of four rolling drive motors, when selecting the model, the two rolling drive motors that drive the rear rolling assembly can choose a model with a rated power smaller than the rated power of the two rolling drive motors that drive the front rolling assembly. This is not only more economical than four rolling drive motors with the same rated power (the rated power is the rated power of the one with the largest rated power among the four), but also can be optimized in terms of its weight, volume, structure, material and other aspects.

[0117] Another embodiment of the present invention, in addition to the above-mentioned embodiment, also includes a guide member, which can be arranged between the relatively lower area between the preceding first rotating rolling member and the preceding second rotating rolling member and the relatively upper area between the following first rotating rolling member and the following second rotating rolling member.

[0118] When in operation, the guide member is used to guide the grains that have been rolled for the first time from the relatively lower area between the first rotating rolling member and the second rotating rolling member to the relatively upper area between the first rotating rolling member and the second rotating rolling member, so as to reduce the deviation of the grains from their preset movement trajectory during the movement, so that the grains that have been rolled for the first time can basically enter the rear rolling assembly for the second rolling, making it possible to increase the total shelling rate of a certain number of grains.

[0119] As an example of the guide member, Figure 7 , 8 As shown, it includes a guide plate 501 , and the two lateral sides of the guide plate 501 are bent upward to form a blocking portion 502 .

[0120] The guide plate 501 is arranged to be inclined downward to facilitate the grains to slide down so as to enter the subsequent rolling assembly.

[0121] Another embodiment of the present invention, in addition to the above-mentioned embodiments, may also include a first distance adjustment component and / or a second distance adjustment component.

[0122] The preceding distance adjusting component and / or the following distance adjusting component are used to adjust the distance between the preceding first rotating rolling component and the preceding second rotating rolling component and between the following first rotating rolling component and the following second rotating rolling component respectively.

[0123] Since the radially outward working surfaces of the first preceding rotating rolling member and the second preceding rotating rolling member and the first following rotating rolling member and the second following rotating rolling member will be worn due to friction after working for a period of time, the spacing between the first preceding rotating rolling member and the second preceding rotating rolling member and between the first following rotating rolling member and the second following rotating rolling member will become larger, which greatly affects the shelling efficiency of the grains. Therefore, after working for a period of time, it is necessary to manually adjust the spacing between the first preceding rotating rolling member and the second preceding rotating rolling member and between the first following rotating rolling member and the second following rotating rolling member, which is time-consuming and laborious. For this reason, the above-mentioned prior distance adjustment component and / or the subsequent distance adjustment component are provided.

[0124] Pre-adjustment components

[0125] The prior distance adjustment component cooperates with the prior first rotating rolling part or the prior second rotating rolling part. The prior distance adjustment component includes a prior distance adjustment rotating arm and a prior distance adjustment driver. The prior distance adjustment rotating arm has the function of rotating under the drive of the prior distance adjustment driver. The prior first rotating rolling part or the prior second rotating rolling part can be arranged on the prior distance adjustment rotating arm. When the prior distance adjustment rotating arm rotates, the prior first rotating rolling part or the prior second rotating rolling part arranged thereon also moves at the same time, thereby changing the distance between the prior first rotating rolling part and the prior second rotating rolling part.

[0126] An example of the prior adjustable distance arm is as follows: Figure 3 , 5 7, a prior distance adjustment rotating seat 611 of a seat-type structure is shown, and the prior distance adjustment rotating seat 611 cooperates with the prior distance adjustment rotating shaft 612. When the prior distance adjustment rotating seat 611 rotates, it rotates around the prior distance adjustment rotating shaft 612.

[0127] An example of the prior pitch adjustment drive is as follows: Figure 3 , 5 As shown in , 7, it is a driving cylinder 621 for prior distance adjustment, and its movable end cooperates with the prior distance adjustment rotating seat 611 to drive the prior distance adjustment rotating seat 611 to rotate around the prior distance adjustment rotating shaft 612 within a preset angle range.

[0128] After the distance adjustment component

[0129] The rear distance adjustment component cooperates with the rear first rotating rolling part or the rear second rotating rolling part. The rear distance adjustment component includes a rear distance adjustment rotating arm and a rear distance adjustment driver. The rear distance adjustment rotating arm has the function of rotating under the drive of the rear distance adjustment driver. The rear first rotating rolling part or the rear second rotating rolling part can be arranged on the rear distance adjustment rotating arm. When the rear distance adjustment rotating arm rotates, the rear first rotating rolling part or the rear second rotating rolling part arranged thereon also moves at the same time, thereby changing the distance between the rear first rotating rolling part and the rear second rotating rolling part.

[0130] An example of a rear-end adjustment arm is shown in FIG. Figure 3 , 5 7, a rear distance adjustment rotating seat 711 of a seat-type structure is shown, and the rear distance adjustment rotating seat 711 cooperates with the rear distance adjustment rotating shaft 712. When the rear distance adjustment rotating seat 711 rotates, it rotates around the rear distance adjustment rotating shaft 712.

[0131] An example of a post-adjustment actuator is Figure 3 , 5 As shown in , 7, it is a driving cylinder 721 for rear distance adjustment, and its movable end cooperates with the rear distance adjustment rotating seat 711 to drive the rear distance adjustment rotating seat 711 to rotate around the rear distance adjustment rotating shaft 712 within a preset angle range.

[0132] Yet another embodiment of the present invention, in addition to the above-mentioned embodiments, further includes a prior manual operation component and / or a subsequent manual operation component.

[0133] The first manual operation component and the second manual operation component respectively perform targeted manual operations (such as maintenance, observation, etc.) on the first rolling component and the second rolling component.

[0134] Prior manual operation components

[0135] An example of the prior manual operation component includes a prior manual operation port 811 , a prior manual operation door 812 , and a prior manual observation window 813 provided on the prior manual operation door 812 .

[0136] The first manual operation opening 811 is opened on the housing 1 to correspond to the first rolling assembly. The first manual operation door 812 is hinged on the first manual operation opening 811 and can be opened and closed at the first manual operation opening 811.

[0137] The prior manual observation window 813 is provided on the prior manual operation door 812, and can observe the working status of the prior rolling assembly located inside the housing 1, so that the operator can grasp the working status of the prior rolling assembly in time.

[0138] Post-manual operation components

[0139] An example of the rear manual operation component includes a rear manual operation port 911 , a rear manual operation door 912 , and a rear manual observation window 913 opened on the rear manual operation door 912 .

[0140] The rear manual operation opening 911 is opened on the housing 1 to correspond to the rear rolling assembly. The rear manual operation door 912 is hinged on the rear manual operation opening 911 and can be opened and closed at the rear manual operation opening 911.

[0141] The subsequent manual observation window 913 is provided on the prior manual operation door 912, and can observe the working status of the subsequent rolling assembly located inside the housing 1, so that the operator can timely grasp the working status of the subsequent rolling assembly.

[0142] It should be noted that the above-mentioned embodiments of the present invention can be used not only for the shelling operation of millet, but also for the shelling operation of other types of cereals that are smaller in volume than rice or wheat. Of course, it can also be fully applied to the shelling operation of larger-volume cereals such as rice and wheat.
