Description

Technical Field

[0001] This utility model belongs to the technical field of grain processing equipment, and in particular, it is a device for preventing clogging of a grain elevator. Background Technology

[0002] Grain elevators are commonly used equipment in grain processing to lift grain from a lower to a higher level for further processing. The hopper, a crucial component of the grain elevator, is used for loading and transporting grain. However, in actual use, hopper blockage is a frequent problem. Traditional anti-blockage hopper devices for grain elevators can meet basic anti-blockage requirements, but weak adaptive anti-blockage capabilities can significantly reduce the actual operating time of the grain elevator, severely decrease production efficiency, and fail to meet expected processing output targets.

[0003] A search revealed Chinese patent document (authorization announcement number CN218369577U), indicating that this utility model relates to the technical field of feeding devices, and particularly to an anti-clogging device for a hopper and a hopper assembly. The hopper assembly includes a hopper and an anti-clogging device. The anti-clogging device includes a flexible shaft and a drive motor. One end of the flexible shaft is connected to the drive motor, and the other end is connected to an eccentric flexible oscillating component. The eccentric flexible oscillating component extends into the lower part of the hopper. When the flexible shaft drives the eccentric flexible oscillating component to oscillate, the end of the eccentric flexible oscillating component approaches or contacts the inner wall of the hopper. Therefore, during the oscillation process of the eccentric flexible oscillating component, most of the material adhering to the inner wall of the hopper can be shaken off, thus achieving a good crushing effect and effectively preventing blockage at the hopper outlet. This device can meet basic anti-clogging requirements. However, if the adaptive anti-clogging capability is weak, it will lead to a significant reduction in the actual operating time of the grain elevator, a severe decrease in production efficiency, and an inability to meet the expected processing output target. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging hopper device for a grain elevator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging hopper device for a grain elevator, comprising an elevator protective cover for protecting grain from leakage during the elevator lifting process, one end of the elevator protective cover being connected to an anti-clogging hopper, fixed columns welded to both sides of the anti-clogging hopper, hollow columns installed inside the fixed columns, a second spring connected inside the hollow columns, a movable column connected to one end of the second spring, the movable column sliding inside the hollow columns, a guide block installed on one side of the movable column, a rotating column rotatably connected to the other side of the movable column, a V-shaped guide plate for preventing grain clogging installed on the outer periphery of the rotating column, and a semi-cylinder installed at the bottom of the V-shaped guide plate.

[0006] Preferably, a second motor is installed on the vertical inner wall of the anti-blocking bucket, the output shaft of the second motor is connected to a cam via a coupling, and a support frame is welded to the vertical inner wall of the anti-blocking bucket.

[0007] Preferably, the top of the anti-blocking hopper is connected to a feeding hopper, and the side of the feeding hopper is symmetrically connected to multiple rotating shafts, each of which has an elliptical cylinder installed on its outer periphery.

[0008] Preferably, a first spring is provided on the outer periphery of the plurality of rotating shafts, one end of the first spring is connected to the inner wall of the feed hopper, and the other end of the first spring is connected to an elliptical cylinder.

[0009] Preferably, a first motor is installed on the side of the hoist protective cover, and the output shaft of the first motor is connected to a roller via a coupling. A conveyor belt is meshed with the outer circumference of the roller.

[0010] Preferably, the outer periphery of the conveyor belt is equipped with multiple lifting plates for lifting grain, one end of the elevator protective cover is provided with a feed inlet, and the other end of the elevator protective cover is provided with a discharge outlet.

[0011] Preferably, the end of the elevator protective cover near the discharge port is connected to a discharge pipe, and a buffer tank is provided at the bottom of the discharge pipe.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This anti-clogging hopper device for grain elevators benefits from its structure. When the amount of grain entering the machine increases, the grain squeezes the V-shaped guide plate, causing it to deflect. The V-shaped guide plate then presses down on the rotating column, which in turn presses down on the second spring. This causes the V-shaped guide plate to move downwards, activating the second motor. The second motor drives the cam to rotate, and the protruding part of the cam contacts the edge of the semi-cylinder. The V-shaped guide plate can then reciprocate within a certain angle, preventing grain blockage. Compared to traditional anti-clogging hopper devices for grain elevators, which have weak adaptive anti-clogging capabilities, this structure enhances these capabilities, significantly increasing the actual operating time of the grain elevator and improving production efficiency, thus meeting the expected processing output target.

[0014] The anti-clogging hopper device used in this grain elevator benefits from the structure of the feed hopper. When grain is added to the feed hopper, it comes into contact with the elliptical cylinder, causing the elliptical cylinder to rotate at a certain angle. Due to the action of the first spring, when the grain is no longer in contact with the elliptical cylinder, the first spring can drive the elliptical cylinder to return to its original position, which can prevent the grain from clogging at the feed hopper.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0025] like Figures 1 to 5The illustrated anti-blocking hopper device for a grain elevator includes an elevator protective cover 1 for preventing grain leakage during the elevator lifting process. One end of the elevator protective cover 1 is connected to an anti-blocking hopper 3. Fixed columns 301 are welded to both sides of the anti-blocking hopper 3. Hollow columns 302 are installed inside the fixed columns 301. A second spring 303 is connected inside the hollow column 302. One end of the second spring 303 is connected to a movable column 304. The movable column 304 slides inside the hollow column 302. A guide block 305 is installed on one side of the movable column 304. A rotating column 306 is rotatably connected to the other side of the movable column 304. A V-shaped guide plate 307 for preventing grain blockage is installed on the outer periphery of the rotating column 306. When the grain enters the anti-blocking hopper 3, it contacts the V-shaped guide plate 307 and slides into the elevator protective cover 1 along the edge of the V-shaped guide plate 307 and the feed inlet 105. A semi-cylinder 403 is installed at the bottom of the V-shaped guide plate 307.

[0026] A second motor 4 is installed on the vertical inner wall of the anti-blocking hopper 3. The output shaft of the second motor 4 is connected to a cam 401 via a coupling. A support frame 402 is welded to the vertical inner wall of the anti-blocking hopper 3. When the amount of grain entering increases, the grain squeezes the V-shaped guide plate 307, which can produce a certain amount of offset. The V-shaped guide plate 307 presses down on the rotating column 306, which in turn presses down on the second spring 303. The V-shaped guide plate 307 moves downward, activating the second motor 4. The second motor 4 drives the cam 401 to rotate. The protruding part of the cam 401 contacts the edge of the semi-cylinder 403, and the V-shaped guide plate 307 can reciprocate within a certain angle, which can prevent the grain from becoming blocked.

[0027] The top of the anti-blocking hopper 3 is connected to the feed hopper 2. Multiple rotating shafts 201 are symmetrically rotatably connected to the side of the feed hopper 2. Elliptical cylinders 203 are installed on the outer periphery of each of the multiple rotating shafts 201. A first spring 202 is set on the outer periphery of the multiple rotating shafts 201. One end of the first spring 202 is connected to the inner wall of the feed hopper 2, and the other end of the first spring 202 is connected to the elliptical cylinder 203. When grain is added to the feed hopper 2, the grain comes into contact with the elliptical cylinder 203, and the elliptical cylinder 203 rotates at a certain angle. Due to the action of the first spring 202, when the grain is not in contact with the elliptical cylinder 203, the first spring 202 can drive the elliptical cylinder 203 to return to its original position, which can prevent the grain from blocking at the feed hopper 2.

[0028] A first motor 101 is installed on the side of the elevator protective cover 1. The output shaft of the first motor 101 is connected to a roller 102 via a coupling. A conveyor belt 103 is meshed with the outer periphery of the roller 102. Multiple lifting plates 104 for lifting grain are installed on the outer periphery of the conveyor belt 103. A feed inlet 105 is provided at one end of the elevator protective cover 1, and a discharge outlet 106 is provided at the other end. When the first motor 101 is turned on, the first motor 101 drives the roller 102 to rotate. The roller 102 drives the conveyor belt 103 and the lifting plates 104 to move. The lifting plates 104 lift the grain from the bottom of the elevator protective cover 1 to the discharge outlet 106.

[0029] The end of the elevator protective cover 1 near the discharge port 106 is connected to a discharge pipe 107. A buffer tank 108 is installed at the bottom of the discharge pipe 107. Grain is discharged from the discharge pipe 107 and falls into the buffer tank 108. The buffer tank 108 can be rotated to recover the grain. The buffer tank 108 can be connected to an external support frame. The output pipe of the buffer tank 108 can rotate to facilitate multi-directional grain recovery. The grain elevator uses an anti-clogging hopper device, which is equipped with a support structure to ensure the stability of the hopper device during operation. The support structure is usually composed of several metal pillars. One end of the pillar is fixed to the ground foundation or equipment frame, and the other end is connected to the bottom or side of the hopper body. The number and distribution of the pillars are reasonably designed according to the size and weight of the hopper. Large hoppers may require more and stronger pillars to provide sufficient support to ensure that the hopper remains stable and does not shake or shift when bearing the weight of the full load of grain and the force generated by the vibration mechanism.

[0030] Working principle

[0031] This grain elevator uses an anti-clogging hopper device. During operation, grain is added to the feed hopper 2, and the grain contacts the elliptical cylinder 203. The elliptical cylinder 203 rotates at a certain angle. Due to the action of the first spring 202, when the grain is no longer in contact with the elliptical cylinder 203, the first spring 202 drives the elliptical cylinder 203 back to its original position, preventing blockage at the feed hopper 2. When the grain enters the anti-clogging hopper 3, it contacts the V-shaped guide plate 307 and slides along the edge of the V-shaped guide plate 307 and the feed inlet 105 into the elevator's protective cover 1. The first motor 101 is then activated, driving the roller 102 to rotate. The roller 102 then moves the conveyor belt 103 and the lifting plate 104, thus lifting the grain. Plate 104 lifts the grain from the bottom of the elevator protective cover 1 to the discharge port 106. Finally, the grain is discharged from the discharge pipe 107 and falls into the buffer tank 108. The buffer tank 108 can be rotated to recover the grain. When the amount of grain entering increases, the grain squeezes the V-shaped guide plate 307, which can produce a certain amount of deviation. The V-shaped guide plate 307 presses down the rotating column 306, which in turn presses down the second spring 303. The V-shaped guide plate 307 moves downward, turning on the second motor 4. The second motor 4 drives the cam 401 to rotate. The protruding part of the cam 401 contacts the edge of the semi-cylinder 403. The V-shaped guide plate 307 can reciprocate within a certain angle, which can prevent the grain from clogging.
