Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain lifting equipment technology, specifically to an anti-clogging grain lifting machine. Background Technology
[0002] Bucket elevators are continuous conveying machines that use a series of buckets uniformly fixed to an endless traction component to vertically lift materials. Bucket elevators use a series of buckets fixed to a traction chain or belt to transport bulk materials upward in a vertical or near-vertical direction.
[0003] During grain harvesting and storage, large impurities such as stones, wood blocks, and straw inevitably get mixed in. Most existing grain elevators lack effective impurity screening devices, allowing these large impurities to enter the elevator along with the grain. As the equipment operates, these impurities can easily become stuck between various parts of the elevator. Furthermore, when feeding the elevator, a large amount of grain rushes into the guide frame, resulting in excessive grain flow. This excessive flow can cause grain to accumulate inside the elevator, leading to blockages and affecting normal grain transport. Therefore, a blockage-resistant grain elevator is proposed.

[0032] Example
[0033] Please see Figure 1-6 This utility model provides a technical solution: a clog-resistant grain elevator, including a bucket elevator body 1, a guide frame 2 connected to one side of the bottom of the bucket elevator body 1, and a feeding frame 3 fixed to the top of the guide frame 2. The feeding frame 3 is used to add the grain to be lifted. The grain to be lifted can be evenly added through a belt conveyor. A filter screen 7 with a hole diameter of 5mm-10mm is inserted inside the feeding frame 3. A sealing ring is fixed to the outside of the filter screen 7, and the sealing ring is clamped between the filter screen 7 and the feeding frame 3. The filter screen 7 is used to screen out large impurities. The grain is added from the feeding frame 3, and the filter screen 7 inserted inside the feeding frame 3 is used to screen out large impurities, ensuring that only grain of suitable particle size enters the lifting process.
[0034] The filter screen 7 is fixed around the top of the four sides with limit frames 71. The limit frames 71 are connected to the top of the feeding frame 3 by bolts. The filter screen 7 can be removed and replaced by removing the bolts on the limit frames 71. The filter screen 7 is fixed to the top of the feeding frame 3 by the limit frames 71 and bolts, which is convenient for disassembly and replacement. At the same time, the sealing ring on the outside of the filter screen 7 enhances the sealing performance and prevents grain leakage. The feeding frame 3 is provided with a discharge component 6 on one side. The discharge component 6 is used to prevent grain blockage inside the bucket elevator body 1.
[0035] The discharge assembly 6 includes a shielding frame 64 and a baffle 68. A discharge trough 69 is provided on one side of the baffle 68. A second rotating shaft 611 is rotatably connected to the inner wall of the shielding frame 64 via a bearing. A base 612 is fixed to the top of the second rotating shaft 611. A first rotating shaft 61 is provided on the top of the base 612. Several stirring rods 62 are fixed to the outside of the first rotating shaft 61. The shielding frame 64 is fixed to the inside of the guide frame 2. The inclined surface at the top facilitates the sliding of grain. The shielding frame 64 completely covers the second pulley 610, the second rotating shaft 611, and the outside of the belt, preventing the grain from contacting the belt and affecting the transmission. The discharge trough 69 is located below the filter screen 7. The baffle 68 is rotatably connected to the bottom of the filter screen 7. There is a gap of 5mm-10mm between the baffle 68 and the filter screen 7. Only the part of the discharge trough 69 that is connected to the filter screen 7 can allow the grain inside the feeding frame 3 to fall. The shape of the discharge trough 69 can be fan-shaped or arc-shaped to prevent a large amount of grain from entering the inside of the guide frame 2 at once.
[0036] The first rotating shaft 61 has a screw hole on its inner side, which is connected to the base 612 by bolts. A cover plate 63 is connected to the top of the screw hole. The cover plate 63 can be connected to the screw hole by threads, and the top of the cover plate 63 has a slotted or cross-shaped groove to facilitate the rotation of the cover plate 63 with a screwdriver to remove it. When the filter screen 7 needs to be replaced, the screw connection between the first rotating shaft 61 and the base 612 needs to be removed first. The outer side of the base 612 is inserted into the center of the filter screen 7. The filter screen 7 has a connection hole in the center. A sealing gasket is fixed to the inner wall of the connection hole. The sealing gasket is made of food-grade wear-resistant rubber and is a replaceable structure (not shown in the figure) to prevent the grain from contacting the base 612. The base 612 passes through the connection hole. A protective box 4 is fixed to one side of the guide frame 2. A motor 66 and a gear reducer 67 are installed on the bottom of the inner wall of the protective box 4. The motor 66 is installed in the protective box 4 and drives the first pulley 65 to rotate after the speed is adjusted by the gear reducer 67.
[0037] The output shaft of motor 66 is fixed to the input shaft of gear reducer 67. A first pulley 65 is fixed to the output shaft of gear reducer 67. A second pulley 610 is fixedly sleeved on the outside of second shaft 611. The first pulley 65 and the second pulley 610 are connected by a belt. The first pulley 65 is connected to the second pulley 610 by the belt. The second pulley 610 is fixed to the second shaft 611. The second shaft 611 is rotatably connected to the shielding frame 64 through a bearing and drives the base 612 to rotate. A heat dissipation hole is opened on one side of the protective box 4, and a filter screen is installed on the side of the heat dissipation hole. In this embodiment, a dustproof bearing is preferably used.
[0038] The shielding frame 64 is fixed to the inner side of the guide frame 2. The top of the shielding frame 64 is provided with an inclined surface. The baffle 68 is rotatably connected to the inner side of the guide frame 2 through a dustproof bearing. The baffle 68 is fixed to the outer side of the second rotating shaft 611 at its axis. The shielding frame 64 completely covers the second pulley 610, the second rotating shaft 611 and the outer side of the belt to prevent the grain from contacting the belt.
[0039] A discharge rack 5 is provided on one side of the top of the bucket elevator body 1. Several buckets 9 are connected to the inside of the bucket elevator body 1. A through hole 8 is provided on one side of the bottom of the guide rack 2. Grain falling from the discharge chute 69 enters the bottom of the inner side of the bucket elevator body 1 through the through hole 8 under the guiding action of the guide rack 2. The buckets 9 are driven by the drive mechanism (not shown in the figure) of the bucket elevator body 1 to lift the grain from the bottom to the top. Then, the lifted grain is discharged through the discharge rack 5 provided on one side of the top of the bucket elevator body 1, thus completing the grain lifting process.
[0040] Working principle: The grain to be lifted is added into the feeding rack 3. A filter screen 7 is inserted inside the feeding rack 3. When the grain passes through the filter screen 7, large impurities are screened out and remain above the filter screen 7, while qualified grain falls through the filter screen 7. A sealing ring is fixed on the outside of the filter screen 7. The sealing ring is clamped between the filter screen 7 and the feeding rack 3 to seal and prevent the grain from leaking from the gap between the filter screen 7 and the feeding rack 3. Limiting frames 71 are fixed around the top of the filter screen 7. The limiting frames 71 are connected to the top of the feeding rack 3 by bolts. When the filter screen 7 needs to be replaced, the bolts on the limiting frames 71 are removed to take out the filter screen 7.
[0041] Start the motor 66 inside the protective box 4. The output shaft of the motor 66 drives the input shaft of the gear reducer 67 to rotate. After being reduced by the gear reducer 67, its output shaft drives the first pulley 65 to rotate. Since the first pulley 65 and the second pulley 610 are connected by a belt, the second pulley 610 rotates synchronously with the first pulley 65, thereby driving the second rotating shaft 611, which is fixedly sleeved with the second pulley 610, to rotate.
[0042] When the second rotating shaft 611 rotates, it drives the baffle 68 fixed on its outer side to rotate inside the guide frame 2. The top of the baffle 68 is slidably connected to the bottom of the filter screen 7. Only when the discharge chute 69 on the baffle 68 rotates to the position communicating with the filter screen 7 can the filtered grain in the feeding frame 3 fall through the discharge chute 69. The discharge chute 69 prevents a large amount of grain from entering the guide frame 2 instantly.
[0043] On the other hand, the base 612 at the top of the second rotating shaft 611 rotates with it. The base 612 passes through the connecting hole in the center of the filter screen 7 and is connected to the screw hole on the inner side of the first rotating shaft 61 by bolts, thereby driving the first rotating shaft 61 to rotate. Several stirring rods 62 on the outer side of the first rotating shaft 61 rotate synchronously to stir the grain on the filter screen 7 and prevent the grain from accumulating and clogging the filter screen 7.
[0044] Grain falling from the discharge chute 69 is guided by the guide frame 2 and enters the bottom of the bucket elevator body 1 through the through hole 8 on one side of the bottom of the guide frame 2. When the bucket elevator body 1 is running, several buckets 9 connected to its inner side continuously scoop up the grain at the bottom and move upward with the elevator transmission structure. When the buckets 9 move to the top of the bucket elevator body 1, they dump the grain out and finally complete the output of the grain through the discharge frame 5 on one side of the top of the bucket elevator body 1, thus realizing the grain lifting operation.
[0045] In summary, by adding the grain that needs to be lifted into the feeding rack 3, and using the filter screen 7 inserted on the inside, large impurities will be screened out and left above the filter screen 7 as the grain passes through. The top of the filter screen 7 is fixed with limit frames 71 around all four sides, and the limit frames 71 are connected to the top of the feeding rack 3 by bolts. When the filter screen 7 needs to be replaced, simply remove the bolts on the limit frames 71 to easily remove the filter screen 7. The operation is simple and quick, reducing the difficulty and time cost of equipment maintenance and improving work efficiency.
[0046] The second rotating shaft 611 drives the baffle 68 to rotate inside the guide frame 2. The top of the baffle 68 is slidably connected to the bottom of the filter screen 7. Only when the discharge chute 69 on the baffle 68 rotates to the position communicating with the filter screen 7 can the filtered grain in the feeding frame 3 fall through the discharge chute 69. This realizes the control of grain discharge, avoids a large amount of grain entering the guide frame 2 instantly, prevents equipment blockage or grain spillage caused by excessive grain flow, and ensures the stability and uniformity of the grain conveying process.
[0047] When the second rotating shaft 611 rotates, it is connected to the first rotating shaft 61 through the base 612 and drives it to rotate, causing several stirring rods 62 on the outside of the first rotating shaft 61 to rotate synchronously, stirring the grain on the filter screen 7. The rotation of the stirring rods 62 can break up the accumulated grain and improve the grain filtration efficiency.
