Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of material distribution funnels, and particularly relates to a two-in-one seamless connection material distribution funnel for raw millet and rice processed by a rice huller. BACKGROUND

[0002] In the field of agricultural machinery equipment, a material distribution funnel is a key equipment for realizing classified conveying of granular materials such as millet, and is widely used in scenes such as storage and transfer of raw millet, subsequent processing of millet after rice hulling, etc., and its performance directly affects the efficiency of agricultural production and processing and the utilization rate of materials.

[0003] When the two funnel bodies of the traditional split type material distribution funnel are connected with upstream and downstream equipment, seamless connection of the channel is difficult to achieve due to the limitation of structural design, and material leakage and material channeling are prone to occur during material conveying, resulting in incomplete distribution. At the same time, due to the gap at the connection, part of the material cannot accurately enter the target conveying channel, and the equipment needs to be repeatedly operated to handle the residual material, causing the equipment to run for a long time, increasing energy consumption, accelerating the wear of equipment parts, and reducing the service life of the equipment.

[0004] In order to avoid the above technical problems, it is necessary to provide a two-in-one seamless connection material distribution funnel for raw millet and rice processed by a rice huller to overcome the defects in the prior art. SUMMARY

[0005] The purpose of the present application is to provide a two-in-one seamless connection material distribution funnel for raw millet and rice processed by a rice huller to solve the problems raised in the background.

[0006] To achieve the above purpose, the present application provides the following technical scheme: a two-in-one seamless connection material distribution funnel for raw millet and rice processed by a rice huller, comprising a funnel body, an opening and closing assembly connected inside the funnel body, an intermediate plate connected in the middle of the inside of the funnel body, a guide plate connected to the top of the intermediate plate, and a first sealing gasket and a second sealing gasket connected to the inner wall of the funnel body and one side of the intermediate plate.

[0007] The opening and closing assembly comprises a first air cylinder and a second air cylinder, the output end of the first air cylinder is connected with a first connecting rod, one end of the first connecting rod is rotatably connected with a first connecting piece, one end of the first connecting piece is rotatably connected with a first connecting shaft, the outer side of the first connecting shaft is welded with a first sealing plate, the output end of the second air cylinder is connected with a second connecting rod, both ends of the second connecting rod are rotatably connected with a second connecting piece, both ends of the second connecting piece are rotatably connected with a second connecting shaft, and the outer side of the second connecting shaft is welded with a second sealing plate.

[0008] As a preferred embodiment, the funnel body has a first channel and a second channel inside, which are located on both sides of the middle plate, respectively.

[0009] As a preferred embodiment, a first discharge port is connected to the top of one side of the funnel body, and a second discharge port is connected to the bottom of one side of the funnel body. The first sealing plate is located on one side of the first discharge port, and the second sealing plate is located on one side of the second discharge port.

[0010] In a preferred embodiment, there are two of each of the first sealing gasket and the second sealing gasket. The two first sealing plates are movably connected to the top and bottom of the first sealing plate, respectively, and the two second sealing gaskets are movably connected to the bottom and top of the second sealing plate, respectively.

[0011] As a preferred embodiment, gravity sensors are provided on the top of both the first and second sealing plates. A controller is connected to one side of the funnel body. The controller is equipped with a touch screen and an emergency stop button. A PLC module is integrated inside the controller. The PLC module is electrically connected to the solenoid valves of the first and second cylinders respectively. The controller is connected to the gravity sensors via remote communication signals.

[0012] In a preferred embodiment, both the first connecting shaft and the second connecting shaft are connected through the funnel body, and one end of each of the first connecting shaft and the second connecting shaft is connected to an expansion bolt, and the number of expansion bolts is two.

[0013] In a preferred embodiment, a connecting plate is connected to the top of the funnel body, and the surfaces of the guide plate and the intermediate plate are provided with a smooth coating, which is a polytetrafluoroethylene coating. The top of the funnel body is connected to the raw material millet conveying pipe and the millet output pipe of the rice huller respectively through the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention, through the tight fit of the first and second sealing gaskets with the first and second sealing plates respectively, can completely fill the channel gaps, preventing leakage and cross-contamination of raw millet and millet from the huller during the conveying process. At the same time, the smooth polytetrafluoroethylene coating reduces millet residue in the channel, further ensuring thorough diversion and eliminating processing duplication or waste caused by material mixing. The independent channels separated by the intermediate plate are designed to accommodate raw millet with intact particles and external impurities, and millet from the huller with bran and a brittle texture, in the second channel and the first channel. The guide plate can guide the two types of millet precisely into the corresponding channels, avoiding conveying problems caused by differences in physical properties. It has strong versatility and can meet the diversion needs of the two core materials in the millet processing production line.

[0016] This invention, based on the intelligent control of PLC module and gravity sensor, can realize automatic channel switching without frequent manual operation, reducing labor costs; at the same time, the sealing plate is driven by cylinder, which greatly improves the working efficiency of the equipment and reduces labor costs.

[0017] In this invention, the first connecting shaft and the second connecting shaft are fixed by expansion bolts, and there is no axial movement during the transmission process, which reduces the wear of the connecting parts. The polytetrafluoroethylene coating not only improves the flowability of materials, but also reduces the frictional wear of millet on the channel wall, reduces equipment wear, and increases the service life of the equipment.

[0025] The present invention will be further described below with reference to embodiments.

[0026] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0027] Please see Figures 1-6 The present invention provides a two-in-one seamless connection feeding funnel for raw millet and millet from a huller, including a funnel body 1, an opening and closing component 2 connected inside the funnel body 1, an intermediate plate 3 connected in the middle inside the funnel body 1, a guide plate 4 connected to the top of the intermediate plate 3, and a first sealing gasket 5 and a second sealing gasket 6 connected to the inner wall of the funnel body 1 and one side of the intermediate plate 3.

[0028] The opening and closing assembly 2 includes a first cylinder 201 and a second cylinder 206. The output end of the first cylinder 201 is connected to a first connecting rod 202. One end of the first connecting rod 202 is rotatably connected to a first connecting member 203. One end of the first connecting member 203 is rotatably connected to a first connecting shaft 204. A first sealing plate 205 is welded to the outside of the first connecting shaft 204. The output end of the second cylinder 206 is connected to a second connecting rod 207. The two ends of the second connecting rod 207 are rotatably connected to a second connecting member 208. The two ends of the second connecting member 208 are rotatably connected to a second connecting shaft 209. A second sealing plate 210 is welded to the outside of the second connecting shaft 209.

[0029] The intermediate plate 3 divides the rice millet into a first channel 7 and a second channel 8. The second channel 8 is adapted for conveying raw millet, and the first channel 7 is adapted for conveying millet from a rice huller. The first cylinder 201 and the second cylinder 206 in the opening and closing assembly 2 are connected by cylinders, connecting rods, and connecting parts. The transmission structure of the connecting shaft drives the sealing plate to rotate. When the output end of the first cylinder 201 extends or retracts, it drives the first connecting piece 203 to rotate through the first connecting rod 202, thereby causing the first connecting shaft 204 to drive the first sealing plate 205 to open and close, realizing the on / off control of the first channel 7 and the first discharge port 11. The second cylinder 206 drives the second sealing plate 210 to control the on / off of the second channel 8 and the second discharge port 12. The first connecting shaft 204 and the second connecting shaft 209 are fixed by the expansion bolts 13 to ensure that there is no axial movement during the transmission process and the sealing plate switching is accurate. The first sealing gasket 5 and the second sealing gasket 6 on one side of the middle plate 3 and the inner wall of the funnel body 1 are in contact with the top and bottom of the first sealing plate 205 and the second sealing plate 210, respectively. When the sealing plate is closed, the sealing gasket can fill the gap between the sealing plate and the channel wall, completely blocking the leakage and cross-flow path of material. At the same time, the smooth polytetrafluoroethylene coating reduces the residue of millet in the channel and further avoids the mixing of materials after diversion.

[0030] like Figures 2-5 As shown, the present invention provides an embodiment in which a first channel 7 and a second channel 8 are provided inside the funnel body 1, and the first channel 7 and the second channel 8 are respectively located on both sides of the intermediate plate 3.

[0031] The present invention provides an embodiment in which a first discharge port 11 is connected to the top of one side of the funnel body 1, a second discharge port 12 is connected to the bottom of one side of the funnel body 1, a first sealing plate 205 is located on one side of the first discharge port 11, and a second sealing plate 210 is located on one side of the second discharge port 12.

[0032] The present invention provides an embodiment in which there are two first sealing gaskets 5 and two second sealing gaskets 6. The two first sealing plates 205 are movably connected to the top and bottom of the first sealing plate 205, respectively, and the two second sealing gaskets 6 are movably connected to the bottom and top of the second sealing plate 210, respectively.

[0033] The present invention provides an embodiment in which gravity sensors are provided on the top of the first sealing plate 205 and the second sealing plate 210. A controller 10 is connected to one side of the funnel body 1. The controller 10 is equipped with a touch screen and an emergency stop button. The controller 10 integrates a PLC module. The PLC module is electrically connected to the solenoid valves of the first cylinder 201 and the second cylinder 206 respectively. The controller 10 is connected to the gravity sensors through a remote communication signal.

[0034] The present invention provides an embodiment in which the first connecting shaft 204 and the second connecting shaft 209 are both connected through the funnel body 1, and one end of the first connecting shaft 204 and the second connecting shaft 209 is connected to an expansion bolt 13, and the number of expansion bolts 13 is two.

[0035] The present invention provides an embodiment in which a connecting plate 9 is connected to the top of the funnel body 1, and the surfaces of the guide plate 4 and the intermediate plate 3 are provided with a smooth coating, which is a polytetrafluoroethylene coating. The top of the funnel body 1 is connected to the raw material millet conveying pipe and the millet output pipe of the rice huller respectively through the connecting plate 9.

[0036] The guide plate 4 on the top of the intermediate plate 3 and the smooth polytetrafluoroethylene coating on its surface can guide the two types of millet into their respective channels, avoiding mixing during initial feeding and reducing friction between the millet and the channel wall to prevent adhesion and accumulation. The gravity sensors on the top of the first sealing plate 205 and the second sealing plate 210 can detect the weight of the millet in the corresponding channel in real time and transmit the signal to the controller 10 via remote communication. After receiving the signal, the PLC module inside the controller 10 automatically judges the material level in the channel and then controls the solenoid valves of the first cylinder 201 and the second cylinder 206 to achieve automatic switching of the sealing plates. In addition, the touch screen of the controller 10 can display the equipment status in real time, and the emergency stop button can quickly cut off the cylinder action in case of failure to ensure safe operation of the equipment.

[0037] The working principle and usage process of this invention are as follows: First, the funnel is connected to the raw millet conveying pipe and the millet output pipe of the rice huller via the connecting plate 9 at the top of the funnel body 1, ensuring that the raw millet conveying pipe is aligned with the upper part of the second channel 8. The millet output pipe of the rice huller is temporarily not feeding material. The operator selects the raw millet mode through the touch screen of the controller 10, or the gravity sensor detects that raw millet is falling into the upper part of the second channel 7. The PLC module in the controller 10 sends an energizing command to the solenoid valve of the first cylinder 201. Then, the output end of the first cylinder 201 extends, pushing the first connecting rod 202 to move, causing the first connecting piece 203 to rotate around the first connecting shaft 204, so that the first sealing plate 205 closes around the first connecting shaft 204, and the first channel 7 and the first discharge port 11 are closed. At the same time, the PLC... The module controls the second cylinder 206 solenoid valve to be de-energized, the first sealing plate 205 remains closed, blocking the first channel 7. The raw millet is guided into the second channel 7 by the guide plate 4. The raw millet is finally transported to the downstream huller through the first discharge port 11. Finally, when the raw millet is transported, the gravity sensor detects that the weight in the first channel 7 has dropped below the threshold and sends a signal to the controller 10. The PLC module controls the first cylinder 201 solenoid valve to be de-energized, the output end of the first cylinder 201 retracts, driving the first sealing plate 205 to close, the first channel 7 opens, and the millet can be transported to the huller.
