Description

Technical Field

[0001] The invention belongs to the field of rice husker, and relates to an uneven blowing device for the rice husker. The wind force is controlled by moving a wind shield up and down, and in particular to an uneven blowing device and a rice husker. Background Art

[0002] With the current increase in population, the demand for food supply is increasing, so rice hullers are being used more and more widely. According to field surveys and responses from grain factory personnel, the key components currently used for husking are two large rubber rollers with the same initial radius, and the rice husking machine works in three shifts, 24 hours a day, which causes great wear on the rubber rollers. After the rice husking machine has been husked unevenly for many times, the diameter of the rubber roller of the rice husking machine is different in different places, resulting in different distances between the rotating shafts of the rubber rollers.

[0003] In the operation process of a traditional rice husker, rice enters the rice husker, passes through the flow plate and enters the rubber roller, and this process flows down automatically. Since the surface of the rubber roller is unevenly worn and the distance between the rotating shafts of the rubber rollers is different, the rice does not fall evenly when passing through the rubber rollers, and the husk mixture separated by the rubber rollers is also uneven when passing through the blowing device. However, the wind blown out of the blowing port of the traditional rice husker has the same wind force at all places under the rubber roller. Therefore, for the unevenly falling husk mixture, the traditional hair dryer cannot achieve an efficient blowing effect, which seriously affects the husk separation rate.

[0004] After searching, it is known that there is no uneven blowing device on the market, which is indispensable in actual production activities. Therefore, it is necessary to design an uneven blowing device and a rice huller with the device. Summary of the invention

[0005] The purpose of the present invention is to design an uneven blowing device and a rice husker with the device. The diameter of the rubber roller of the rice husker changes due to the uneven friction of the rice for many times. After the rice is husked by the rubber roller, the separated husks fall unevenly on various parts of the rubber roller. The present invention improves this by using an uneven blowing device.

[0006] According to one aspect of the present invention, there is provided an uneven blowing device, the device comprising:

[0007] The housing has an air inlet at one end and an air outlet panel at the other end, wherein the air outlet panel has multiple rows of air holes;

[0012] Furthermore, the windshield block driving unit includes an electric push rod, a telescopic end of the electric push rod is connected to the windshield block, and a motor of the electric push rod is electrically connected to the control unit.

[0013] Furthermore, the windshield block driving unit includes a plurality of electric push rods, the number of the electric push rods is the same as the number of the windshield blocks, and each electric push rod corresponds to a windshield block.

[0014] Furthermore, the plurality of wind shields are arranged on the outer surface of the air outlet panel, and when the wind shields are in a retracted state, they do not block the air outlet holes, and when the wind shields are in an extended state, they block part or all of the air outlet holes.

[0015] According to another aspect of the present invention, a rice husker is provided, comprising an uneven blowing device.

[0016] Furthermore, the uneven blowing device is located below the two rubber rollers, and the air outlet of the uneven blowing device corresponds to below the gap between the two rubber rollers.

[0017] Furthermore, it also includes a rubber roller gap measuring device for obtaining the gap data between the two rubber rollers and sending it to the control unit of the uneven blowing device.

[0018] Furthermore, it also includes an air guide plate, which is arranged opposite to the uneven blowing device. The air guide plate is obliquely arranged on the inner wall of the rice husker, and one end of the air guide plate is connected to the rice husk outlet.

[0028] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] The present invention is an improved design of the blowing device of the rice husker, and its main design point is to divide the air outlet of the blowing device into multiple independent modules, that is, to set multiple rows of vertically arranged blowing outlets on the air outlet panel, and each row has an independently controlled windshield at the upper end. In the operation process of the rice husker, when the rice enters the rice husker, it enters the rubber roller through the flow plate, and this process flows down automatically. Therefore, when the rice enters the rubber roller, it does not fall evenly everywhere, which leads to that after the long-term shelling friction of the rubber roller, the diameter of the rubber roller of the rice husker is different in various places, so the husk mixture separated by the rubber roller is also uneven wherever it passes through the blowing device. The present invention can detect the diameter size of each place of the rubber roller, and then transmit its diameter information to the control unit. The control unit controls the amplitude of the up and down movement of the windshield block on the uneven blowing device through information aggregation, so as to control the wind force size in various places and achieve a more efficient blowing effect.

[0030] The present disclosure provides an uneven blowing device, which comprises:

[0031] The housing has an air inlet at one end and an air outlet panel at the other end, wherein the air outlet panel has multiple rows of air holes;

[0032] A fan, arranged in the housing and located between the air inlet and the air outlet panel;

[0033] A plurality of wind shields are telescopically arranged in the housing, each wind shield corresponding to a row of wind holes;

[0034] A windshield block driving unit, disposed in the housing and connected to the windshield block, and used to drive the windshield block to telescope;

[0035] A control unit is electrically connected to the fan and the windshield drive unit, and is used to control the start and stop of the fan and the windshield drive unit.

[0036] Furthermore, the windshield block driving unit includes an electric push rod, the telescopic end of the electric push rod is connected to the windshield block, and the motor of the electric push rod is electrically connected to the control unit. The windshield block driving unit includes a plurality of electric push rods, the number of which is the same as the number of windshield blocks, and each electric push rod corresponds to a windshield block. The electric push rod is an existing product, also known as a linear drive, which is mainly a new type of linear actuator composed of a motor push rod and a control device, and its specific structure is not described in detail in this article.

[0037] Furthermore, the plurality of windshields are arranged on the outer surface of the air outlet panel, and when the windshields are in a retracted state, they do not block the air outlet holes, and when the windshields are in an extended state, they block part or all of the air outlet holes. The control unit can adjust the length of the windshields by controlling the rotation time or number of revolutions of each electric push rod, thereby accurately controlling the air volume of each column of air outlets.

[0038] The uneven blowing device of the present invention can adjust the air volume of the air outlet by arranging a wind shield block to move up and down on the air outlet panel to block part or all of the air outlets, thereby achieving uneven blowing.

[0039] According to another aspect of the present invention, a rice husker is provided, comprising an uneven blowing device, wherein the uneven blowing device is located below two rubber rollers, and the air outlet of the uneven blowing device corresponds to below the gap between the two rubber rollers.

[0040] Furthermore, a rubber roller gap measuring device is included, which is used to obtain the gap data between the two rubber rollers and send it to the control unit of the uneven blowing device. There are many methods in the prior art that can be used to measure the diameter of the rubber roller, such as displacement sensor measurement, angle magnification method, etc.

[0041] The control unit adjusts the telescopic length of the windshield according to the gap data between the two rubber rollers, thereby controlling the air volume. Where the diameter of the rubber roller is small, that is, where the gap between the two rubber rollers is large, the windshield of the control air hole of the uneven blower below is extended short, so that each column of vertical air outlet holes is more, and the wind blown out is a little stronger. In this way, the larger the gap between the two rubber rollers and the more husk mixture falls, the stronger the wind blown by the uneven blower below, and vice versa.

[0042] Furthermore, it also includes an air guide plate, which is arranged opposite to the uneven blowing device, and the air guide plate is obliquely arranged on the inner wall of the rice husker, and one end is connected to the rice husk outlet. Preferably, the inclination angle of the air guide plate is roughly close to the angle of the wind blown out of the air outlet, guiding the rice husk to be blown out from the rice husk outlet along the direction of the air guide plate.

[0043] Furthermore, it also includes an air inlet duct, one end of which is connected to the air inlet of the uneven blowing device, and the other end of which extends to the outside of the casing of the rice husker.

[0044] Furthermore, the length of the air outlet panel of the uneven blowing device is the same as the length of the rubber roller. The air outlet panel is located at the lower side of the rubber roller, and the length of the air outlet panel is close to the length of the rubber roller, so that the husks falling from every part of the rubber roller can be blown away. Moreover, the multiple rows of air outlets vertically set up on the air outlet panel basically realize that each row of air outlets corresponds to a small section of the rubber roller, and the gaps between the rubber rollers at different positions are different. The blowing efficiency can be improved by adjusting the air volume of the corresponding row of air outlets.

[0045] The working process of the rice husker of the present invention is as follows:

[0046] When the rice husker is started, the rice enters the rubber roller, which separates it by friction.

[0047] The husk mixture falls off the rubber roller. Due to the long-term uneven friction, the diameters of different places of the rubber roller are different, so the husk mixture falls unevenly.

[0048] The control unit collects signals from the diameters of the rubber rollers at various locations, processes these signals, and thereby adjusts the extension and retraction of the windshield of the uneven blowing device below the rubber roller. Usually, where the diameter of the rubber roller is small, that is, where the gap between the two rubber rollers is large, the windshield of the uneven blowing device below is shorter, and there are more vertical air outlets in this column, and the wind blown out is a little stronger. In other words, the larger the gap between the two rubber rollers and the more husk mixture falls, the stronger the corresponding wind blown by the uneven blowing device below. Conversely, when the gap between the two rubber rollers is smaller, the less husk mixture falls from here, and then the control unit controls the windshield below here to extend out to block part of the blowing outlet according to the signal here, and the number of remaining air outlets is reduced, thereby controlling the size of the wind force.

[0049] Finally, the chaff is blown out from the direction of the wind guide plate.

[0050] To facilitate understanding of the solution and effects of the embodiments of the present invention, a specific application example is given below. Those skilled in the art should understand that this example is only for facilitating understanding of the present invention, and any specific details thereof are not intended to limit the present invention in any way.
