[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] In the present application, the rice machine referred to may be a rice polisher or a rice mill, or may be other equipment that is used for both rice screening and rice bran collecting hopper.

[0043] In the following, the rice machine is described as a rice polishing machine, but it should be understood that the rice machine may also be other devices mentioned above.

[0044] like Figures 1 to 6 As shown, the utility model provides a rice leakage detection device, which is built into the rice chaff collecting bucket 1 of the rice machine, and includes a fixing component 2 and a vibration sensor 3, wherein the fixing component 2 is used to connect to the chaff collecting bucket 1; the vibration sensor 3 is connected to the fixing component 2.

[0045] When the rice polisher is working, the rice enters the rice sieve, and the rice bran adhered to the rice can be removed by the friction between the rice and the friction between the rice and the rice sieve. After the rice bran friction reaches the fineness of movement, it leaks out from the sieve holes of the rice sieve. When the sieve holes of the rice sieve are blocked, or the rice sieve bursts due to other reasons, the rice will flow out from the broken opening of the rice sieve, and the flowed rice will hit the bran collecting bucket 1 and / or the vibration sensor 3. The vibration sensor 3 can detect the abnormal fluctuation, and judge that the rice polisher has leaked rice through the detected abnormal fluctuation, so the rice leakage of the rice polisher can be detected in time.

[0046] It should be understood that the vibration sensor 3 is connected to the control host of the rice polisher, and the control host is connected to the alarm. After the control host detects the abnormal vibration signal of the vibration sensor 3, the control alarm will sound an alarm.

[0047] It should be understood that the model of the vibration sensor 3 may be K-2155, the model of the control host may be PLC S7-200, and the model of the alarm may be E3JK-DS30MS-2CH.

[0048] It should be understood that the vibration sensor 3 can also be a vibration alarm, which detects the vibration parameters of mechanical equipment and emits an audible and visual alarm when the vibration value exceeds a preset alarm threshold. The model of the vibration alarm can be Xinjia's XJ-100 and Bonru brand PA-950, etc.

[0049] It should be understood that the innovation of the present application lies in detecting whether the rice sieve is leaking rice by means of a built-in vibration sensor 3 in the bran collecting bucket 1. It is an existing technology that the vibration sensor 3 detects abnormalities and issues an alarm based on the abnormalities. For example, announcement No. CN207559719U discloses obtaining the vibration intensity of the vibration sensor 3 by controlling the host, and controlling whether the buzzer emits an alarm sound through the obtained vibration intensity signal.

[0050] In one of the embodiments, the rice leakage detection device further includes a rice connection plate 4, the rice connection plate 4 is connected to the fixing component 2, the vibration sensor 3 is connected to the rice connection plate 4, and is connected to the fixing component 2 via the rice connection plate 4.

[0051] By setting up the rice receiving plate 4, the vibration sensor 3 is connected to the fixed component 2 through the rice receiving plate 4. When the rice falls, it hits the rice receiving plate 4. The rice receiving plate 4 can amplify the vibration received by the rice leakage vibration sensor 3. Moreover, the size of the rice receiving plate 4 is larger than that of the vibration sensor 3. The larger rice receiving plate 4 can more easily contact the falling rice.

[0052] In one embodiment, the vibration sensor 3 is arranged on the side of the rice receiving plate 4 away from the feeding end of the bran collecting bucket 1.

[0053] Through the above arrangement, when rice bran and rice fall, they hit the side of the rice receiving plate 4 close to the feeding end of the rice bran collecting bucket 1, which can prevent the vibration sensor 3 from contacting the falling rice bran and rice, thereby extending the service life of the vibration sensor 3.

[0054] In one embodiment, the number of the meter-connecting plates 4 is two, and the two meter-connecting plates 4 are symmetrically arranged on both sides of the fixing component 2; the number of the vibration sensors 3 is at least two, and at least two vibration sensors 3 are respectively arranged on the two meter-connecting plates 4.

[0055] By providing two rice receiving plates 4 and two vibration sensors 3, when rice hits the rice receiving plates 4, both rice receiving plates 4 can withstand the impact, thereby increasing the contact area with the falling rice, and the two symmetrically arranged rice receiving plates 4 can offset the residual vibration caused by the rice hitting the rice receiving plates 4.

[0056] In one embodiment, the fixed component 2 includes a fixed tube 21, which is connected to the bran collecting bucket 1. The fixed tube 21 has a wiring channel 21a formed along the axial direction, a wiring port 21b at the bottom of the fixed tube 21 is connected to the wiring channel 21a, and the rice receiving plate 4 is connected to the fixed tube 21.

The cables and control lines that pass through are electrically connected to the vibration sensor 3, which can prevent the cables or control lines from contacting the rice bran and falling rice.

[0058] In one embodiment, the two rice-joining plates 4 are connected, and a circular arc structure is formed at the connection, and the two rice-joining plates 4 are sleeved on the fixing pipe 21 via the circular arc structure.

[0059] Through the above arrangement, the rice-joining plate 4 can fit the fixed tube 21 , the contact area between the rice-joining plate 4 and the fixed tube 21 is increased, and the rice-joining plate 4 is easily fixed to the fixed tube 21 .

[0060] It should be understood that the two rice receiving plates 4 are symmetrically arranged on both sides of the fixed tube 21, and the two rice receiving plates 4 are inclined, and the distance between the two rice receiving plates 4 gradually increases in the direction away from the fixed tube 21. Through the above arrangement, after the rice and rice bran hit the rice receiving plate 4, they can slide along the inclined surface of the rice receiving plate 4, so that the rice and rice bran fall off the rice receiving plate 4.

[0061] In one embodiment, the connecting plate 4 is detachably connected to the fixing pipe 21.

[0062] By detachably connecting the connecting plate 4 to the fixed tube 21, the various components can be formed separately and then combined by splicing, wherein the arc structure formed between the two connecting plates 4 can be formed by bending the plate material through a bending structure, and two connecting plates 4 and the above-mentioned arc structure are formed by bending the plate material, and then the formed connecting plate 4 is connected to the fixed tube 21.

[0063] It should be understood that the connecting plate 4 and the fixing pipe 21 can be detachably connected by means of bolts, screws, buckles, etc.

[0064] In one embodiment, at least one threaded hole is formed on the top of the fixing tube 21; at least one fixing hole is formed in the arc structure relative to the threaded hole; the leakage rice detection device also includes at least one fixing screw, and the fixing screw 5 passes through the fixing hole and is threadedly connected to the threaded hole.

[0065] When it is necessary to connect the connecting plate 4 with the fixed tube 21, the arc structure between the two connecting plates 4 is sleeved on the fixed tube 21, and the fixing holes are aligned with the threaded holes. Then, the fixing screws 5 are passed through the fixing holes and threadedly connected with the threaded holes, thereby fixing the connecting plate 4 relative to the fixed tube 21.

[0066] In one embodiment, the fixing assembly 2 further includes at least one fixing portion 22, which is connected to the fixing tube 21 and is used for being detachably connected to the bran collecting bucket 1.

[0067] The fixing portion 22 and the bran collecting bucket 1 are fixed in a detachable connection manner, so that the fixing portion 22, the fixing tube 21 and the bran collecting bucket 1 can be formed separately and then assembled by splicing.

[0068] It should be understood that the fixed tube 21 and the bran collecting bucket 1 can be detachably connected by means of bolts, screws, snaps, etc.

[0069] It should be understood that the shape of the fixing portion 22 can be cylindrical, elliptical, bar-shaped, etc., and the number of the fixing portions 22 can be one, two, etc. When the number of the fixing portions 22 is two, the two fixing portions 22 are arranged at both ends of the fixing tube 21 and fit the two opposite inner walls of the fixing tube 21.

[0070] In one of the embodiments, the fixing portion 22 is provided with two through holes, and the bran collecting bucket 1 is provided with two oval holes opposite to the two through holes. The connecting bolt 6 is passed through the mounting hole and the through hole, the nut 7 is arranged on the side of the fixing portion 22 away from the bran collecting bucket 1, and the connecting bolt 6 is threadedly connected, thereby achieving the fixation of the fixing portion 22 relative to the bran collecting bucket 1, and also achieving the fixation of the fixing tube 21 relative to the bran collecting bucket 1.

[0071] The utility model also relates to a rice machine, comprising the above-mentioned rice leakage detection device and the rice bran collecting bucket 1.

[0072] In one embodiment, the bran collecting bucket 1 is provided with a wire entry hole 1a relative to the wiring channel 21a, the wire entry hole 1a is connected to the wiring channel 21a, and the wiring channel 21a of the fixing portion 22 is provided with a wire passing hole.

[0073] By setting the wire entry hole 1a, the control wire can pass through the wire entry hole 1a and enter the wiring channel 21a, and pass through the wiring port 21b through the wiring channel 21a, and then connect with the vibration sensor 3, so that the control wire can be prevented from contacting the falling rice and rice bran throughout the process.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
