Description

Technical Field

[0001] This utility model relates to the field of grain processing equipment technology, and in particular, to a rice milling machine discharge device. Furthermore, this utility model also relates to a rice milling unit including the aforementioned rice milling machine discharge device. Background Technology

[0002] Rice milling is a crucial step in paddy processing, removing the bran or germ from brown rice to produce finished rice that meets quality standards. This process is primarily achieved using a rice milling machine. The core structure of the machine is the whitening chamber, where brown rice passes through which the bran layer is removed before exiting through the discharge gate. The pressure at the discharge gate directly determines the pressure inside the whitening chamber, affecting the rice grain retention time and milling intensity. These are key parameters for controlling the whitening uniformity, broken rice rate, and energy consumption of the rice milling machine. Furthermore, current rice milling processes often employ "multi-machine light milling" technology. By connecting multiple machines in series, the internal pressure and temperature rise of a single machine are effectively reduced. This technology not only significantly increases the working area per unit output but also ensures processing quality and reduces the broken rice rate.

[0003] However, current rice milling machine discharge gate pressure adjustments are mainly made manually by increasing the number of pressure rollers or adjusting their position on the pressure roller rod. This adjustment method is not flexible enough and has relatively low accuracy. Furthermore, in actual processing, if a downstream device becomes clogged, material from the upstream process continues to flow into the downstream device. Conversely, if the downstream device is clogged, the material cannot flow in and instead spills onto the ground, causing cleaning difficulties. Additionally, when processing different raw materials, it is necessary to change the curved discharge nozzle, and automatic switching is not possible, making process adjustments inconvenient. Summary of the Invention

The controller and the drive component are electrically connected and used to transmit control commands to the drive component. The drive component drives the rotating shaft to rotate, thereby driving the discharge gate to rotate via the connecting rod, thus controlling the opening and closing amplitude of the discharge gate and controlling the material flow rate.

[0006] As a further improvement to the above technical solution:

[0007] Furthermore, the diversion assembly includes a controller two, a drive component two, a rotating shaft two connected to the output end of the drive component two, and a diversion plate fixedly connected to the rotating shaft two. The rotating shaft two is rotatably arranged at the boundary between the first flow channel and the second flow channel. The controller two is point-connected to the drive component two and is used to transmit control commands to the drive component two. The drive component two is used to drive the rotating shaft two to rotate, thereby driving the diversion plate to rotate, thereby controlling the material to flow into the first flow channel or the second flow channel.

[0008] Furthermore, the diversion assembly also includes a material sensor 1 for detecting the material condition in the first flow channel and transmitting a signal to the controller 2, and a material sensor 2 for detecting the material condition in the second flow channel and transmitting a signal to the controller 2. Both material sensor 1 and material sensor 2 are electrically connected to the controller 2.

The rectifier gate has a clearance opening for the connecting rod to pass through.

[0011] Furthermore, the rice milling discharge diversion device also includes a sampling door rotatably arranged on the discharge housing, which is used to rotate relative to the discharge housing to open a sampling port communicating with the inner cavity of the discharge housing.

[0012] Furthermore, the sampling door has multiple heat dissipation holes arranged in a mesh pattern.

[0013] According to another aspect of the present invention, a rice milling unit is also provided, which includes the above-mentioned rice milling discharge diversion device.

[0014] As a further improvement to the above technical solution:

[0015] Furthermore, the rice milling unit includes N rice milling machines connected in series, and N rice discharge diversion devices are provided. The rice milling machines and rice discharge diversion devices are arranged in a one-to-one correspondence.

The material flow rate is directly proportional to the discharge pressure of the rice milling machine. By controlling the material flow rate, the discharge pressure of the rice milling machine can be flexibly and precisely adjusted as needed, resulting in good whitening uniformity, low breakage rate, and high efficiency. Low energy consumption; material diversion and conveying are achieved through the first flow channel, the second flow channel, and the diversion component. When adjusting and switching processes, the diversion component controls the material to enter the first or second flow channel as needed. When downstream equipment is blocked, the diversion component changes the material flow direction for material discharge, preventing the material from continuing to flow into downstream equipment and thus preventing the material from falling to the ground. Compared with existing technologies, this solution offers flexible and precise adjustment of the discharge gate pressure, which is beneficial to improving processing quality and avoids the troublesome material cleaning when the equipment is blocked. At the same time, process adjustment and switching are convenient, making it highly practical and suitable for widespread promotion and application.

[0030] like Figures 1-4 As shown, the rice milling discharge diversion device of this embodiment includes a discharge housing 10, an inlet formed on the discharge housing 10 for communicating with the discharge end of the rice milling machine, a discharge gate 20 arranged inside the discharge housing 10 for controlling the material flow rate, a gate control assembly 30 arranged on the discharge housing 10 for controlling the opening and closing range of the discharge gate 20, a first flow channel 40 arranged inside the discharge housing 10 for outputting material, a second flow channel 50 arranged inside the discharge housing 10 for outputting material, and a control assembly 30 arranged on the discharge housing 10 for... A diversion assembly 60 is used to control the flow of material into the first flow channel 40 or the second flow channel 50; the gate control assembly 30 includes a controller (not shown), a drive component, a rotating shaft 34 connected to the output end of the drive component, and a connecting rod 35 connected to the rotating shaft 34 and the discharge gate 20 respectively. The controller and the drive component are electrically connected and used to transmit control commands to the drive component. The drive component is used to drive the rotating shaft 34 to rotate, so as to drive the discharge gate 20 to rotate through the connecting rod 35, thereby controlling the opening and closing range of the discharge gate 20, and thus controlling the material flow rate.

[0031] like Figures 1-4As shown, specifically, the rice milling discharge diversion device of this utility model is connected to the rice milling machine through the discharge housing 10, and communicates with the discharge end of the rice milling machine through the feed inlet. During the processing, the material processed by the rice milling machine enters the discharge housing 10 through the feed inlet. The control gate assembly 30 transmits control commands to the drive component through the controller, which drives the rotating shaft 34 to rotate, thereby driving the discharge gate 20 to rotate through the connecting rod 35, thus controlling the opening and closing range of the discharge gate 20. The material flow rate is proportional to the discharge pressure of the rice milling machine, thereby controlling the material flow rate. The discharge pressure of the rice milling machine can be flexibly and accurately adjusted as needed, resulting in good whitening uniformity and low breakage rate of the rice milling machine. Low energy consumption; material diversion and conveying are achieved through the first flow channel 40, the second flow channel 50, and the diversion component 60. When adjusting and switching processes, the diversion component 60 controls the material to enter the first flow channel 40 or the second flow channel 50 as needed. When the downstream equipment is blocked, the diversion component 60 changes the material flow direction to discharge the material, preventing the material from continuing to flow to the downstream equipment and thus preventing the material from falling to the ground. Compared with the existing technology, this solution has a flexible and accurate pressure adjustment method for the discharge gate 20, which is conducive to improving processing quality and avoids the trouble of cleaning up materials when the equipment is blocked. At the same time, process adjustment and switching are convenient, and it is highly practical and suitable for widespread promotion and application.

[0032] Optionally, the gate control assembly 30 also includes a gate control sensor for detecting and providing feedback on the material processing effect. The controller precisely controls the opening and closing range of the discharge gate 20 based on the feedback data from the gate control sensor, thereby achieving flexible and precise adjustment of the pressure of the discharge gate 20 and improving the rice milling processing accuracy.

[0033] Optionally, the drive component one includes a servo motor 31, a reducer 32 and a coupling 33 connected in sequence, with the coupling 33 connected to the rotating shaft 34.

[0035] Optionally, controller one is a PLC controller.

[0036] like Figure 2As shown, in this embodiment, the diversion assembly 60 includes a controller (not shown), a drive component 61, a rotating shaft 62 connected to the output end of the drive component 61, and a diversion plate 63 fixedly connected to the rotating shaft 62. The rotating shaft 62 is rotatably positioned at the boundary between the first flow channel 40 and the second flow channel 50. The controller is point-connected to the drive component 61 and is used to transmit control commands to the drive component 61. The drive component 61 drives the rotating shaft 62 to rotate, thereby causing the diversion plate 63 to rotate, thus controlling the material to flow into the first flow channel 40 or the second flow channel 50. Specifically, during processing, according to work requirements, the diversion assembly 60 transmits control commands to the drive component 61 through the controller. The drive component 61 drives the rotating shaft 62 to rotate according to the control commands, thereby causing the diversion plate 63 to rotate, thus controlling the material to flow into the first flow channel 40 or the second flow channel 50.

[0037] Optionally, controller two is a PLC controller.

Both material sensor 1 and material sensor 2 are electrically connected to the controller 2. Specifically, when the controller 2 transmits a control command to the drive component 2 61, the drive component 2 61 drives the rotating shaft 2 62 to rotate according to the control command, thereby driving the diversion plate 63 to rotate, thus controlling the material to flow into the first flow channel 40 or the second flow channel 50. The material sensor 1 detects the material condition in the first flow channel 40 and transmits a signal to the controller 2, and the material sensor 2 detects the material condition in the second flow channel 50 and transmits a signal to the controller 2. The controller 2 can accurately determine whether the material diversion result meets the working requirements based on the material condition in the first flow channel 40 and the second flow channel 50.

[0041] Optionally, sensor mounting base one and sensor mounting base two are respectively arranged on the opposite side walls of the discharge housing 10, with material sensor one arranged on sensor mounting base one and material sensor two arranged on sensor mounting base two.

Specifically, when processing viscous materials, the third controller 75 operates, so that the power source supplies current to the electric heating element 71 through the second wire 76 and the first wire 74, and controls the current magnitude. The electric heating element 71 operates and transmits heat into the discharge housing 10 through the heat-resistant layer 72 to improve the flowability of the material and prevent viscous materials from sticking to the discharge housing 10.

[0043] Optionally, the fastener 73 is a combination of bolts and nuts.

[0044] Optionally, the controller 375 is a PLC controller.

[0045] like Figure 2 As shown, in this embodiment, the rice milling discharge diversion device also includes a rectifier gate 80 rotatably arranged inside the discharge housing 10. The rectifier gate 80 is located between the discharge gate 20 and the rotating shaft 34 and is used to buffer the discharge gate 20. The rectifier gate 80 has a clearance opening for the connecting rod 35 to pass through. Specifically, when material flows into the discharge housing 10 through the inlet and generates a large impact force on the discharge gate 20, the rectifier gate 80 can buffer the discharge gate 20 to prevent the discharge gate 20 from being damaged due to excessive force. The clearance opening allows the connecting rod 35 to pass through to connect the discharge gate 20 and the rotating shaft 34 respectively.

[0046] like Figure 1 As shown, in this embodiment, the rice milling discharge diversion device further includes a sampling door 90 rotatably mounted on the discharge housing 10. The sampling door 90 is used to rotate relative to the discharge housing 10 to open a sampling port communicating with the inner cavity of the discharge housing 10. Specifically, by rotating and opening the sampling door 90, materials in the inner cavity of the discharge housing 10 can be sampled through the sampling port, allowing for accurate judgment of processing quality.

[0047] Optionally, the sampling gate 90 is rotatably mounted on the discharge housing 10 via a hinge.

[0048] like Figure 1 As shown, in this embodiment, the sampling gate 90 is provided with multiple heat dissipation holes 91 arranged in a mesh pattern. Specifically, the heat dissipation holes 91 dissipate the internal heat of the discharge housing 10 to avoid excessive heat inside the discharge housing 10 affecting the material processing quality.

[0049] The rice milling unit of this embodiment includes the aforementioned rice discharge diversion device. Specifically, by employing the aforementioned rice discharge diversion device in the rice milling unit, during process adjustment and switching, the diversion component 60 controls the material to enter the first flow channel 40 or the second flow channel 50 as needed. When the downstream equipment is blocked, the diversion component 60 changes the material flow direction to prevent the material from continuing to flow to the downstream equipment, thereby preventing the material from falling to the ground and avoiding the troublesome material cleaning when the equipment is blocked. At the same time, process adjustment and switching are convenient, highly practical, and suitable for widespread promotion and application.

[0050] In this embodiment, the rice milling unit includes N rice milling machines connected in series. N rice discharge diversion devices are provided, with each rice milling machine and each device arranged in a one-to-one correspondence. The discharge end of each rice milling machine is connected to its inlet, and the inlet end of each rice milling machine is connected to the first flow channel 40. N is an integer greater than 1. Specifically, by having N rice milling machines connected in series, the internal pressure and temperature rise of a single rice milling machine are effectively reduced, significantly increasing the working area per unit output, ensuring processing quality, and reducing the broken rice rate.

[0051] like Figure 4 As shown, in this embodiment, the rice milling machine includes a feeding assembly 200, an auger conveying assembly 300 connected to the feeding assembly 200 for conveying materials in the horizontal direction, a screw propeller 400 connected to the auger conveying assembly 300 for conveying materials in the vertical direction, and a whitening chamber 500 connected to the screw propeller 400 and whose discharge end is connected to the feed inlet. Specifically, the material is conveyed by the feeding assembly 200 to the auger conveyor assembly 300. The auger conveyor assembly 300 conveys the material horizontally to the screw propeller 400. The screw propeller 400 conveys the material vertically upward to the whitening chamber 500. The whitening chamber 500 whitens and discharges the material, which is then conveyed through the inlet to the discharge shell 10. From there, it is conveyed through the discharge shell 10 to the feeding assembly 200 of the next rice milling machine, or to the next process. This vertical structure with low-level feeding and high-level discharge eliminates the need for a lift between the two rice milling machines, reduces rice grain collision and breakage, and lowers the broken rice rate.

[0052] Optionally, the first flow channel 40 flows through the feed assembly 200.
