Description

Technical Field

[0001] The utility model relates to the technical field of grain conveying, in particular to an anti-blocking self-vibrating grain elevator. Background Art

[0002] A grain elevator, also called a grain lift, is a mechanical device mainly used for lifting various grains, dry fuels, fertilizers and other materials from a low place to a high place, and can be connected to conveying devices at different heights to continuously convey the materials.

[0003] However, in the prior art, the existing grain elevator stores grains in a grain storage box inside it through the feeding port. The grain storage box is fixed on the conveyor belt, and the movement of the conveyor belt drives the grain storage box on one side to climb upward. When the grain storage box moves to the top part of the conveyor belt, it will change the movement direction and throw the grains stored in it towards the discharge port, so as to realize the conveying of grains to a high place. However, most grain elevators lack measures to strike and vibrate the grain storage box to make the grains stored in it loose, resulting in that some grains in the grain storage box may not be thrown towards the discharge port in time. Furthermore, the un-thrown grains may be sent to the bottom end inside the grain elevator for accumulation, causing blockage and affecting the normal operation of the grain elevator. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art: most grain elevators lack measures to strike and vibrate the grain storage box to make the grains stored in it loose, resulting in that some grains in the grain storage box may not be thrown towards the discharge port in time. Furthermore, the un-thrown grains may be sent to the bottom end inside the grain elevator for accumulation, causing blockage and affecting the normal operation of the grain elevator.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an anti-blocking self-vibrating grain elevator, including an elevator housing. An upper side and a lower side of one side of the elevator housing are respectively provided with a discharge port and a feeding port, and an upper end and a lower end of an inner surface of the elevator housing are respectively rotatably connected with a driving wheel and a driven wheel. A conveyor belt is arranged on the surfaces of the driving wheel and the driven wheel. A grain conveying box is fixedly connected to the conveyor belt. A motor is fixed on a top side surface of the elevator housing. An output shaft of the motor penetrates through the elevator housing and is fixedly connected to a rotating shaft of the driving wheel. A struck plate is fixedly connected to a top position of an inner surface of the elevator housing, and a side surface of the struck plate is attached to a side surface of the grain conveying box. Smooth convex blocks are fixedly arranged at both side edges of the driving wheel. A fixing rod is fixed on an outer surface of the top of the elevator housing, and a spring is sleeved on an outer surface of the fixing rod. A connecting piece slides on a surface of the fixing rod. One end of the connecting piece is fixedly provided with a striking rod, and the striking rod penetrates through the elevator housing.

[0006] As a preferred embodiment, a feed hopper and a discharge hopper are fixedly connected to the surface of the elevator housing at its feed inlet and discharge outlet respectively.

[0007] As a preferred embodiment, the bottom edge of the grain conveying box is provided with a rounded corner, and the surface of the grain conveying box away from the conveyor belt is attached to the inner surface of the elevator housing.

[0008] As a preferred embodiment, a plurality of the smooth bumps are arranged equidistantly around the driving wheel.

[0009] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0010] In the present utility model, the driving wheel is rotated by the motor, and the rotation of the driving wheel drives the smooth bumps to perform a circular motion. When the smooth bumps move, they will push the striking rods encountered along the way outwards, causing the connecting piece to move and compress the spring. When the smooth bumps leave the position of the striking rods, the spring rebounds to push the connecting piece to move, causing the striking rods to move back to their original positions to strike the struck plate to generate vibration. Since the struck plate is attached to the grain conveying box, the vibration generated will be transmitted to a plurality of grain conveying boxes. By vibration, the grains stored in the grain conveying boxes are loosened, facilitating the timely throwing of all the grains in the grain conveying boxes towards the discharge outlet, effectively avoiding the situation where residual grains are sent to the bottom end of the elevator housing and accumulate, causing blockage.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1

[0018] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: an anti-blocking self-vibrating grain elevator, which includes an elevator housing 1. An outlet and an inlet are respectively provided at the upper end and the lower end of one side of the elevator housing 1. Through the inlet, it is convenient to send the grain into the grain conveying box 5 inside the elevator housing 1 for storage. The grain conveying box 5 throws the grain therein towards the outlet, achieving the purpose of transporting the grain to a higher place. Moreover, a driving wheel 2 and a driven wheel 3 are respectively rotatably connected to the upper and lower ends of the inner surface of the elevator housing 1. A transmission belt 4 is arranged on the surfaces of the driving wheel 2 and the driven wheel 3. The grain conveying box 5 is fixedly connected to the transmission belt 4. The grain conveying box 5 is used for storing grain. A motor 6 is fixed to the side surface of the top of the elevator housing 1. The output shaft of the motor 6 penetrates through the elevator housing 1 and is fixedly connected to the rotating shaft of the driving wheel 2. The transmission belt 4 is installed on the driving wheel 2 and the driven wheel 3 in a relatively tight state, which enables the surface of the transmission belt 4 to closely adhere to the surfaces of the driving wheel 2 and the driven wheel 3, increasing the friction between them. When the motor 6 drives the driving wheel 2 to rotate, the driving wheel 2 can stably drive the transmission belt 4 to move through the friction. When the transmission belt 4 moves, it will also drive the driven wheel 3 to rotate. When the transmission belt 4 moves, one side of the grain conveying box 5 moves upward and the other side of the grain conveying box 5 moves downward. After one side of the grain conveying box 5 rises to the top position of the transmission belt 4, its orientation will change. The grain conveying box 5 with the changed orientation will throw the grain therein towards the outlet, completing the operation of transporting the grain to a higher place. At the top position of the inner surface of the elevator housing 1 where the transmission belt 4 moves, a struck plate 9 is fixedly connected. And the side surface of the struck plate 9 is in contact with the side surface of the grain conveying box 5. Smooth convex blocks 10 are fixedly arranged at both side edges of the driving wheel 2. A fixed rod 11 is fixed to the outer surface of the top of the elevator housing 1. And a spring 12 is sleeved on the outer surface of the fixed rod 11. A connecting piece 13 slides on the surface of the fixed rod 11. One end of the connecting piece 13 is fixedly provided with a striking rod 14, and the striking rod 14 penetrates through the elevator housing 1. By controlling the driving wheel 2 to rotate through the motor 6, the smooth convex blocks 10 are driven to do circular motion. When the smooth convex blocks 10 move, they will push the striking rod 14 encountered along the way outwards, enabling the connecting piece 13 to move and compress the spring 12. When the smooth convex blocks 10 leave the position of the striking rod 14, the spring 12 rebounds to push the connecting piece 13 to move, causing the striking rod 14 to move back to its original position and strike the struck plate 9 to make it vibrate. Since the struck plate 9 is in contact with the grain conveying box 5, the vibration generated by it will be transmitted to multiple grain conveying boxes 5, making the grain stored in the grain conveying boxes 5 loose due to the vibration, facilitating the grain conveying box 5 to timely throw all the grain towards the outlet, effectively avoiding the situation that the remaining grain is sent to the bottom end inside the elevator housing 1 to accumulate and cause blockage.

[0019] Embodiment 2

[0020] As Figures 1-3As shown in the figure, a feed hopper 7 and a discharge hopper 8 are fixedly connected to the surface of the elevator housing 1 at its feed inlet and discharge outlet respectively. With the help of the feed hopper 7, it is convenient to concentrate and send the grains into the grain conveying box 5. With the help of the discharge hopper 8, the concentrated falling point of the thrown grains is provided, which is convenient for receiving the falling grains. The bottom edge of the grain conveying box 5 is set as a rounded corner, and the surface of the grain conveying box 5 far from the conveyor belt 4 is attached to the inner surface of the elevator housing 1. Through the design of the rounded corner, when the grains are thrown by the grain conveying box 5, it effectively prevents the thrown grains from staying on the grain conveying box 5 below, allowing the grains to roll into the discharge hopper 8 through the rounded corner. The design of the conveyor belt 4 with one end surface attached to the inner surface of the elevator housing 1 reduces the gap between them, effectively preventing the grains from rolling into the interior of the elevator housing 1 through the gap. The number of smooth bumps 10 is arranged equidistantly around the driving wheel 2. Increasing the number of smooth bumps 10 can effectively shorten the interval time for the striking rod 14 to be pushed outwards, and improve the striking frequency of the striking rod 14 against the struck plate 9.

[0021] Working principle:

[0022] As Figures 1-3 shown in the figure, when the present utility model is in use, the user first pours the grains into the feed hopper 7. Through the feed hopper 7, the grains are concentrated and roll into the elevator housing 1, and then fall into the grain conveying box 5 for storage. While pouring the grains, the motor 6 is started. The start of the motor 6 drives the rotation of the driving wheel 2. The rotation of the driving wheel 2 drives the movement of the conveyor belt 4. The movement of the conveyor belt 4 drives the rotation of the driven wheel 3. While the conveyor belt 4 is moving, the grain conveying boxes 5 on its left and right sides respectively perform upward and downward movements. During the rotation of the driving wheel 2, the smooth bumps 10 are driven to make a circular motion. During the movement of the smooth bumps 10, the striking rods 14 encountered along the way are pushed outwards. When the striking rods 14 are pushed outwards, the connecting pieces 13 are driven to move along the fixed rods 11, causing the connecting pieces 13 to compress and contract the springs 12. When the smooth bumps 10 move out of the position where the striking rods 14 are located, the springs 12 rebound and push the connecting pieces 13 to move, thereby driving the striking rods 14 to move back to their original positions, causing the striking rods 14 to strike the struck plates 9, making the struck plates 9 vibrate. The vibration generated by the struck plates 9 is transmitted to the multiple grain conveying boxes 5 that move to the top of the conveyor belt 4 for turning. Through the vibration, the grains stored in the grain conveying boxes 5 are loosened, which is convenient for the subsequent throwing of the grains. The grain conveying boxes 5 with changed orientations will throw the grains therein towards the discharge port, causing the grains to fall concentratedly from the discharge hopper 8, thereby completing the operation of transporting the grains to a higher place.

[0023] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
