Description

Technical Field

[0001] This invention belongs to the field of grain processing and conveying technology, specifically a grain processing and conveying equipment. Background Technology

[0002] Grain is an essential commodity in people's daily lives and an important source of income for farmers. Conveyors are needed when storing grain in granaries or transferring grain using transport vehicles. Conveyors are mainly used for bulk grain loading operations in flat warehouses. Grain conveyors mainly consist of a conveying section, a steering section, and a traveling section, and are primarily suitable for loading operations in large and medium-sized grain warehouses.

[0003] A patent with publication number CN119176426B discloses a conveying device for grain processing. This device uses a supply component that presses down, causing an opening component to operate and slit a long opening at the bottom of a grain-filled sack. The grain then pours out through this opening, eliminating the need for manual opening and improving the convenience of grain transportation. Simultaneously, the downward speed of the vertical rod, fixed angle brackets, and bag support frame gradually decreases, preventing impact noise when the bag support frame moves downwards and drives the pressure plate to contact the top of the telescopic boom. This also avoids damage caused by rapid contact and impact between the pressure plate and the telescopic boom, reducing operating noise and extending the device's lifespan. The upward movement of the connecting angle brackets also drives the telescopic crossbar through a connecting block. Vibration is transmitted to the bag support frame via the fixed angle brackets, conveying vertical rod, and connecting angle brackets. Therefore, the bag support frame causes the four positioning steel pins and the sack fixed between them to vibrate together. This vibration of the sack completely emptys the grain, preventing grain residue and ensuring a more thorough emptying process.

[0004] The above-mentioned solution still has some problems in practical application. Usually, workers carry a bag of grain and insert the four corners of the bag into the four fixed cones to open it. Then, a cutting mechanism is used to cut the bottom of the opened bag of grain and open it up. At the same time, a vibrating motor or vibrating mechanism drives the funnel to shake, so that the funnel shakes the bag of grain to quickly shake out and collect the remaining grain. However, after the bag of grain is discharged and collected, the workers need to remove the bag from the fixed cones and then carry another bag of grain and insert it into the fixed cones again. This is not only time-consuming and laborious, but also affects the efficiency of grain discharge and collection.

[0005] Therefore, the present invention provides a grain processing and production conveying device. Summary of the Invention

[0009] The second rotating wheel has multiple slots on its outside, and the first rotating wheel has multiple fixed cones on its outside. The multiple fixed cones are inserted into the slots to fix the two ends of the bagged grain for conveying, which can make the bagged grain gather towards the middle of the bag.

[0010] The second rotating wheel has a fixed column inside, and a cutting blade is provided on the outside of the fixed column. The cutting blade is used to cut the bagged grain to discharge the grain inside for collection.

[0011] Preferably, a U-shaped mounting frame is installed on one side of the fixed frame, a conveyor belt is rotatably connected to the inner cavity of the U-shaped mounting frame, and a pressing roller track is rotatably connected to the upper part of the inner cavity of the U-shaped mounting frame, and the pressing roller track is used to flatten the bagged grain.

[0012] Preferably, two support rollers are fixedly connected between the second rotating wheels, and the two support rollers are respectively fixedly connected between the two second rotating wheels at both ends.

[0013] Preferably, a driven bevel gear is fixedly connected to one end of each of the first rotating wheels, the driven bevel gear is meshed with a transmission bevel gear, a rotating column is fixedly connected inside the transmission bevel gear, a limit groove is formed in the inner wall of the fixed frame, a support block is slidably connected to the inner cavity of the limit groove, and the support block is rotatably connected to the rotating column located on one side of the first rotating wheel.

[0014] Preferably, both ends of the second rotating wheel are rotatably connected to support rods, the support rods are fixedly installed to the inner wall of the fixed frame, and one end of the fixed column passes through the second rotating wheel and is fixedly connected to the support rod.

[0015] Preferably, one end of the first rotating wheel is rotatably connected to a sliding rod, the sliding rod is slidably connected in the inner cavity of the limiting groove, and springs are fixedly connected to the top of the inner cavity of the limiting groove, with one end of each spring being fixed to the support block and the sliding rod respectively.

[0016] Preferably, the lower end of the fixed frame is fixedly connected to a material guide cover, the lower end of the material guide cover is fixedly connected to a folding tube, and the lower end of the folding tube is provided with a grain conveying component, which is used to convey the unpacked grain into the grain silo.

[0017] Preferably, the grain conveying assembly includes a conveying pipe fixedly connected to the lower end of the folded tube, a conveying auger rotatably connected to the inner cavity of the conveying pipe, a drive motor installed at one end of the conveying pipe, and the output shaft end of the drive motor fixed to the conveying auger.

[0018] Preferably, a U-shaped rod is fixedly connected to both sides of the conveying pipe, a pulley is slidably connected to the inner cavity of the U-shaped rod, a connecting rod is rotatably connected inside the pulley, and a slider is fixedly connected to one end of the connecting rod.

[0019] Preferably, the inner wall of the support frame is provided with a groove, the inner cavity of the groove is rotatably connected to a threaded rod, and the slider is threadedly connected to the threaded rod, and a flexible conduit is installed at one end of the delivery pipe.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The grain processing and conveying equipment of the present invention drives a rotating column to rotate by starting a control motor, which in turn drives a transmission bevel gear to mesh with a driven bevel gear. This drives a first rotating wheel to move bagged grain using a fixed cone. During conveying, a support roller lifts the bagged grain entering between the first and second rotating wheels, allowing the first rotating wheel to better utilize the fixed cone inserted into both ends of the bagged grain. After the bagged grain reaches the middle of the fixed frame, without the support roller, it is affected by gravity, causing the grain inside the bag to accumulate in the middle. A cutting blade then cuts the bagged grain in half, allowing for rapid discharge and collection of the grain. Furthermore, the insertion of the fixed cone into both ends of the bag ensures that all the grain is concentrated in the middle, allowing for rapid tilting of the grain after opening the bag, thus improving the discharge efficiency.

[0022] 2. The grain processing and conveying equipment of the present invention, after the bagged grain is cut by the cutting knife, the bagged grain flows into the guide hood. At the same time, the guide hood guides the grain into the folding tube, and then into the conveying pipe. Simultaneously, the drive motor is started to drive the conveying auger to rotate, and the conveying auger agitates the grain for conveying, so as to facilitate the conveying of the grain into the grain silo through the conveying pipe. This solves the problem that in the existing grain processing and conveying equipment, after the bagged grain is opened, the grain is usually conveyed into the grain silo by a conveyor belt. However, the conveyor belt is used to transport the grain, which can easily cause excessive accumulation of grain on the conveyor belt and flow into the conveyor belt, resulting in waste of grain. Moreover, the grain can easily cause jamming and damage to the conveyor belt. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1: As Figures 1 to 7 As shown in the embodiment of the present invention, a grain processing and production conveying equipment includes a support frame 1, a fixed frame 2 is fixedly connected to the upper end of the support frame 1, a dust collector is provided at the upper end of the fixed frame 2 for sucking up the dust generated by the unpacking and discharge of bagged grain 7, protective plates 3 are installed at both ends of the fixed frame 2, and a bag unpacking conveying component 8 is provided in the inner cavity of the fixed frame 2.

[0037] Furthermore, the bag-unpacking and conveying assembly 8 includes a set of first rotating wheels 81 and a set of second rotating wheels 82 symmetrically installed in the inner cavity of the fixed frame 2, wherein both the set of first rotating wheels 81 and the set of second rotating wheels 82 are composed of multiple first rotating wheels 81 and multiple second rotating wheels 82;

[0038] The second rotating wheel 82 has multiple slots 16 on its outside, and the first rotating wheel 81 has multiple fixed cones on its outside. The multiple fixed cones are inserted into the slots 16 to fix the two ends of the bagged grain 7 for conveying, which can make the bagged grain 7 gather towards the middle of the bag.

[0039] The second rotating wheel 82 has a fixed column 87 rotating inside, and a cutting blade 88 is provided on the outside of the fixed column 87. The cutting blade 88 is used to cut the bagged grain 7 to discharge the grain inside for collection.

[0040] Specifically, in existing technologies, workers typically carry a bag of grain and insert the four corners of the bag into four fixed cones to prop open the bag. Then, a cutting mechanism is used to cut the bottom of the opened bag, further propping it open. Simultaneously, a vibrating motor or mechanism drives a funnel to shake, causing the funnel to shake out and collect the remaining grain quickly. However, after the bag of grain is collected, the worker needs to remove the bag from the fixed cones and then carry another bag of grain to insert into the cones again. This is not only time-consuming and labor-intensive but also affects the efficiency of grain collection. Furthermore, carrying a bag of grain and inserting it into the four fixed cones poses a safety hazard if the operator falls and the grain ends up outside the cones. Moreover, the use of a vibrating mechanism to shake out the remaining grain is not only inefficient but also prone to mechanical fatigue and damage after prolonged operation.

[0041] In processing the purchased grain, this invention involves conveying bagged grain 7 into the unpacking and conveying assembly 8 via a conveyor belt. Simultaneously, the first rotating wheel 81 is driven to rotate, and a fixed cone is inserted into both ends of the bagged grain 7. The fixed cone is also inserted into the cavity of the slot 16, driving the bagged grain 7 to move. During this movement, a cutting blade 88 is installed between the second rotating wheels 82, which cuts the bagged grain 7 in half. The middle part of the second rotating wheels 82 is hollowed out. After the first rotating wheel 81 and the second rotating wheel 82 move the bagged grain 7 to the hollowed-out part, the grain's flow causes it to accumulate in the middle. After the cutting blade 88 cuts the bagged grain 7 in half, the grain quickly flows out and is collected. The bag continues to be conveyed by the rotation of the first rotating wheel 81, allowing it to be discharged and collected from one side of the fixed frame 2. This improves the automation level and safety performance of the conveying equipment, thus solving the aforementioned problems.

[0042] like Figure 1 and Figure 2 As shown, a U-shaped mounting frame 4 is installed on one side of the fixed frame 2. A conveyor belt 5 is rotatably connected to the inner cavity of the U-shaped mounting frame 4. A pressing roller track 6 is rotatably connected to the upper part of the inner cavity of the U-shaped mounting frame 4. The pressing roller track 6 is used to flatten the bagged grain 7. A partition is provided on the outside of the conveyor belt 5.

[0043] Specifically, when processing the purchased grain, the bagged grain 7 is placed on the conveyor belt 5, and the conveyor belt 5 is started to move the bagged grain 7. When the bagged grain 7 moves to the pressing roller track 6, the pressing roller track 6, in conjunction with the conveyor belt 5, rolls and flattens the bagged grain 7. The conveyor belt 5 is equipped with partitions on the outside, and the bagged grain 7 is placed between the two partitions. When the bagged grain 7 is rolled and flattened by the pressing roller track 6, the bagged grain 7 can be extended to both ends, so that the conveyor belt 5 can transport the bagged grain 7 between the first rotating wheel 81 and the second rotating wheel 82. The first rotating wheel 81 is fixed by inserting a fixed cone into both ends of the bagged grain 7. At the same time, the first rotating wheel 81 and the fixed cone drive the bagged grain 7 to be transported, thereby improving the efficiency of bagged grain recycling and processing.

[0044] like Figures 3 to 5 and Figure 7 As shown, two support rollers 86 are fixedly connected between the second rotating wheels 82, and the two support rollers 86 are respectively fixed between the two ends of the second rotating wheels 82.

[0045] like Figures 3 to 5 and Figure 7As shown, a driven bevel gear 83 is fixedly connected to one end of the first rotating wheel 81. The driven bevel gear 83 is meshed with a transmission bevel gear 84. A rotating column 85 is fixedly connected inside the transmission bevel gear 84. A limit groove 14 is opened in the inner wall of the fixed frame 2. A support block 15 is slidably connected to the inner cavity of the limit groove 14. The support block 15 is rotatably connected to the rotating column 85 located on one side of the first rotating wheel 81. A control motor is installed at one end of the rotating column 85, and the control motor is installed with the support block 15.

[0046] Specifically, when conveying, cutting, and discharging the bagged grain 7, the control motor drives the rotating column 85 to rotate, which in turn drives the transmission bevel gear 84 to rotate. Simultaneously, the transmission bevel gear 84 meshes with the driven bevel gear 83, causing the driven bevel gear 83 to drive the first rotating wheel 81 to rotate. During rotation, the first rotating wheel 81 uses a fixed cone to move the bagged grain 7. During this process, the support roller 86 lifts the bagged grain 7 between the first and second rotating wheels 82, allowing the first rotating wheel 81 to better utilize the fixed cone to insert into both ends of the bagged grain 7. After the bagged grain 7 reaches the middle of the fixed frame 2, without the support roller 86, it is affected by gravity, causing the bagged grain 7 to... The grain inside the grain 7 is concentrated in the middle of the bag. Then, the cutting blade 88 cuts the bagged grain 7 in half, allowing the grain inside the bag to be quickly discharged and collected. After the first rotating wheel 81 moves the bag to the tail of the fixed frame 2, the support roller 86 lifts the cut bag to prevent it from getting tangled with the first rotating wheel 81. The bag is then conveyed out from inside the fixed frame 2. At this point, a conveyor belt is installed at the tail of the fixed frame 2, which can be used to recycle the bag. This improves the recycling efficiency of the bag after the grain 7 is discharged. It solves the problem that existing grain processing and production conveying equipment has low processing and collection efficiency for bagged grain because it is inconvenient to quickly discharge and recycle the grain inside the bag after discharge.

[0047] like Figures 3 to 5 and Figure 7 As shown, both ends of the second rotating wheel 82 are rotatably connected to support rods 89. The support rods 89 are fixedly installed on the inner wall of the fixed frame 2. One end of the fixed column 87 passes through the second rotating wheel 82 and is fixedly connected to the support rods 89.

[0048] like Figures 3 to 5 and Figure 7 As shown, one end of the first rotating wheel 81 is rotatably connected to a slide rod 17, which is slidably connected in the inner cavity of the limiting groove 14. Springs 18 are fixed to the top of the inner cavity of the limiting groove 14, and one end of the springs 18 is fixed to the support block 15 and the slide rod 17 respectively.

[0049] Specifically, when conveying and discharging bagged grains 7 of different weights, the bagged grains 7 lift the first rotating wheel 81 upward, causing the first rotating wheel 81 to drive the slide rod 17 upward. At the same time, the slide rod 17 drives the support block 15 to slide in the inner cavity of the limiting groove 14, and squeezes the spring 18 upward. The spring 18 then uses its rebound force to push the support block 15 downward. Meanwhile, the support block 15 drives the slide rod 17 and the first rotating wheel 81 to press the bagged grains 7, so as to facilitate the conveying of bagged grains 7 of different thicknesses, ensuring conveying efficiency. This solves the problem that existing grain processing and production conveying equipment is difficult to convey different bagged grains, thus affecting the conveying efficiency of bagged grains.

[0050] Example 2: Figure 1 , Figure 3 and Figure 6 As shown, a guide cover 10 is fixedly connected to the lower end of the fixed frame 2, and a folding tube 12 is fixedly connected to the lower end of the guide cover 10. A grain conveying component 9 is provided at the lower end of the folding tube 12, and the grain conveying component 9 is used to convey the unpacked grain into the grain bin.

[0051] like Figure 2 and Figure 6 As shown, the grain conveying assembly 9 includes a conveying pipe 91 fixedly connected to the lower end of the folded pipe 12. A conveying auger 98 is rotatably connected to the inner cavity of the conveying pipe 91. A drive motor 11 is installed at one end of the conveying pipe 91, and the output shaft end of the drive motor 11 is fixed to the conveying auger 98.

[0052] Specifically, after the bagged grain 7 is cut using the cutting blade 88, the bagged grain 7 flows into the guide hood 10. At the same time, the guide hood 10 guides the grain into the folding tube 12, and then into the conveying pipe 91. Simultaneously, the drive motor 11 is started to drive the conveying auger 98 to rotate, and the conveying auger 98 agitates the grain for conveying, so that the grain can be conveyed into the grain silo through the conveying pipe 91. This solves the problem that in existing grain processing and production conveying equipment, after the bagged grain is unpacked, the grain is usually transported into the grain silo by a conveyor belt. However, when the grain is transported by the conveyor belt, too much grain tends to accumulate on the conveyor belt and flow into the conveyor belt, causing waste of grain. Moreover, the grain can easily cause jamming and damage to the conveyor belt.

[0053] like Figure 2 , Figure 3 and Figure 6 As shown, U-shaped rods 92 are fixedly connected to both sides of the conveying pipe 91. A pulley 93 is slidably connected to the inner cavity of the U-shaped rod 92. A connecting rod 94 rotates inside the pulley 93. A slider 95 is fixedly connected to one end of the connecting rod 94.

[0054] like Figure 2 , Figure 3and Figure 6 As shown, the inner wall of the support frame 1 has a groove 97, and a threaded rod 96 is rotatably connected to the inner cavity of the groove 97. The slider 95 is threadedly connected to the threaded rod 96, and a flexible conduit 13 is installed at one end of the delivery pipe 91.

[0055] Specifically, when conveying grain into the grain silo, the threaded rod 96 is driven to rotate, causing the threaded transmission slider 95 of the threaded rod 96 to slide upward in the inner cavity of the groove 97. This causes the slider 95 to drive the connecting rod 94 to move synchronously. At the same time, the connecting rod 94 drives the pulley 93 to slide in the inner cavity of the U-shaped rod 92. This allows the pulley 93, in conjunction with the connecting rod 94, to adjust the angle of the conveying pipe 91. This adjustment can be made according to the height of the grain silo and the position of the feed inlet. Then, the flexible guide tube 13 is placed into the feed inlet of the grain silo, and the conveying auger 98, in conjunction with the conveying pipe 91, conveys the grain into the grain silo. This solves the problem that existing grain processing and production conveying equipment usually uses conveyor belts to transport grain into the grain silo, but the conveyor belts are difficult to adjust according to the conveying needs, which affects the applicability of the conveying equipment when conveying grain into grain silos of different sizes.

[0056] The working principle is as follows: When processing the purchased grain, the bagged grain 7 is placed on the conveyor belt 5, and the conveyor belt 5 is started to move the bagged grain 7. When the bagged grain 7 moves to the pressing roller track 6, the pressing roller track 6, in conjunction with the conveyor belt 5, rolls and flattens the bagged grain 7. The conveyor belt 5 is equipped with partitions on the outside, and the bagged grain 7 is placed between the two partitions. When the bagged grain 7 is rolled and flattened by the pressing roller track 6, the bagged grain 7 can be extended to both ends, so that the conveyor belt 5 can transport the bagged grain 7 between the first rotating wheel 81 and the second rotating wheel 82. The first rotating wheel 81 is fixed by inserting a fixed cone into both ends of the bagged grain 7. At the same time, the first rotating wheel 81 and the fixed cone drive the bagged grain 7 to be transported, thereby improving the efficiency of bagged grain recycling and processing.

[0057] When conveying, cutting, and discharging the bagged grain 7, the control motor drives the rotating column 85 to rotate, which in turn drives the transmission bevel gear 84 to rotate. Simultaneously, the transmission bevel gear 84 meshes with the driven bevel gear 83, causing the driven bevel gear 83 to drive the first rotating wheel 81 to rotate. During rotation, the first rotating wheel 81 uses a fixed cone to move the bagged grain 7. During this conveying process, the support roller 86 lifts the bagged grain 7 between the first rotating wheel 81 and the second rotating wheel 82, allowing the first rotating wheel 81 to better utilize the fixed cone to insert into both ends of the bagged grain 7. The bagged grain 7 is then conveyed to… After the fixed frame 2 is in the middle, since the bagged grain 7 is not supported by the support roller 86, the bagged grain 7 will be affected by gravity, causing the grain inside the bag to gather in the middle of the bag. Then, the cutting blade 88 is used to cut the bagged grain 7 in half, so that the grain inside the bag can be quickly discharged and collected. After the first rotating wheel 81 drives the bag to the tail of the fixed frame 2, the support roller 86 will lift the cut bag to prevent the bag from getting tangled with the first rotating wheel 81. Then the bag is conveyed out from inside the fixed frame 2. At this time, a conveyor belt is installed at the tail of the fixed frame 2, so that the bags on the conveyor belt can be recycled, which improves the recycling efficiency of the bags after the bagged grain 7 is discharged.

[0058] When transporting grain into the grain silo, the threaded rod 96 is driven to rotate, and the threaded rod 96 drives the slider 95 to slide upward in the inner cavity of the groove 97. This causes the slider 95 to drive the connecting rod 94 to move synchronously. At the same time, the connecting rod 94 drives the pulley 93 to slide in the inner cavity of the U-shaped rod 92. This allows the pulley 93 to work with the connecting rod 94 to adjust the angle of the conveying pipe 91. This adjustment can be made according to the height of the grain silo and the position of the feed inlet. Then, the flexible guide tube 13 is placed into the feed inlet of the grain silo, and the conveying auger 98, in conjunction with the conveying pipe 91, transports the grain into the grain silo.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
