Description

Technical Field

[0001] This utility model relates to an anti-clogging device for grain pits, belonging to the field of grain storage and transportation technology. Background Technology

[0002] In the fields of grain storage, processing and transportation, grain pits are a common type of equipment used for temporary storage and transfer of grain. They are usually set up below a pit or receiving port to collect grain and transport it to subsequent equipment such as conveyors and elevators through discharge pipes. However, in actual use, grain pits and their discharge pipes are prone to blockage, which seriously affects production efficiency and operational safety.

[0003] Traditional grain discharge pits are typically simple in structure, relying mainly on the gravity of the grain itself for flow. However, grains such as wheat, corn, and rice often contain a certain amount of moisture and may contain dust and light impurities, which can easily adhere to, bridge, or arch on the inner wall of the discharge pipe, leading to poor discharge or even complete blockage. Once a blockage occurs, manual intervention is usually required, such as using tools to knock on the pipe or disassembling and cleaning it. This not only increases labor intensity and reduces work efficiency but also poses certain safety risks. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a device for preventing blockage in grain pits.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A grain trough anti-clogging device includes a grain trough, a discharge pipe is provided on one side of the grain trough, a vibrating element is provided on the outside of the discharge pipe, the vibrating element is used to vibrate and transport the grain in the discharge pipe to prevent blockage, and a gate is provided on the side of the discharge pipe away from the grain trough.

[0006] Through the above technical solution, the grain first enters the grain pit for temporary storage, and then the grain flows naturally to the discharge pipe connected to one side of the grain pit. During the process of the grain being transported along the discharge pipe, the vibrating component on the outside of the discharge pipe is activated and generates vibration. The vibration is transmitted to the grain inside the pipe through the pipe wall, keeping the grain in a dynamic state and preventing blockage inside the discharge pipe due to grain clumping or sticking. When it is necessary to control or stop the discharge, the on / off state of the discharge pipe can be switched by operating the gate component on the side of the discharge pipe away from the grain pit.

[0007] The vibration of the vibrating components prevents blockages in the discharge pipe from the source, ensuring the continuity of the grain conveying process and eliminating the need for frequent manual clearing of blockages, thus reducing labor costs. At the same time, the gate components can flexibly control the discharge rhythm to adapt to different subsequent grain processing needs, improving the overall practicality of the device.

[0008] Preferably, the vibrating element is a vibrating motor.

[0009] With the above technical solution, when there is grain being conveyed in the discharge pipe, the vibrating motor, which acts as a vibrating component, is started. After the vibrating motor is powered on, it generates periodic mechanical vibration. The vibration energy is transmitted to the discharge pipe body through the connection structure with the outside of the discharge pipe, causing the discharge pipe to drive the grain inside the pipe to vibrate synchronously. This breaks the static friction and adsorption between grain particles, prevents the grain from accumulating and clumping on the inner wall of the discharge pipe, and ensures that the grain is conveyed smoothly downwards.

[0010] Vibration motors are technologically mature and have a stable and controllable vibration frequency. They can effectively vibrate the grain in the discharge pipe, resulting in significant anti-clogging effects. Furthermore, vibration motors are small in size, easy to install, and convenient for later maintenance and replacement, reducing the difficulty of equipment operation and maintenance. They also have low energy consumption, meeting energy-saving requirements.

[0011] Preferably, the grain storage pit includes a grain storage shell, a filter grid, and an inclined guide plate. The filter grid is disposed on the upper side of the grain storage shell, and the inclined guide plate is disposed on the inner bottom of the grain storage shell.

[0012] With the above technical solution, when the grain falls above the grain pit, it first passes through a filter grid set on the upper side of the grain storage shell. The filter grid blocks impurities mixed in the grain, such as straw and stones, through the gaps in the grid, preventing impurities from entering the inside of the grain storage shell. The filtered grain enters the grain storage shell for temporary storage. The inclined guide plate at the bottom of the inner side of the grain storage shell has an inclined angle, which uses gravity to guide the grain to converge towards the discharge pipe, preventing the grain from accumulating in the bottom corner of the grain storage shell.

[0013] The filter grid can filter out impurities in advance, preventing them from getting stuck in the discharge pipe or damaging subsequent components, thus extending the service life of the device; the inclined guide plate eliminates the dead corners where grain accumulates at the bottom of the grain storage shell, ensuring that the grain can fully and smoothly enter the discharge pipe, improving the storage and guiding efficiency of the grain pit.

[0014] Preferably, the gate component includes a gate frame, a first gate plate component, and a second gate plate component. The gate frame is disposed on one side of the discharge pipe, and the first gate plate component and the second gate plate component are both disposed within the gate frame.

[0015] Through the above technical solution, the gate frame and the side of the discharge pipe away from the grain pit are fixedly connected to form a grain discharge channel frame; the first gate plate and the second gate plate are both assembled inside the gate frame. By controlling the opening and closing states of the first gate plate and the second gate plate respectively, the opening size of the grain channel inside the gate frame can be adjusted, thereby controlling the discharge volume of the discharge pipe, or completely closing the channel and stopping the discharge when needed.

[0016] The dual-gate design makes discharge control more flexible and precise, and can be adapted to the discharge needs of different scenarios. At the same time, the dual-gate structure can improve the sealing performance when the channel is closed, effectively prevent grain leakage, reduce grain loss, and has a higher fault tolerance rate and more reliable operation than a single gate.

[0017] Preferably, the first gate component includes a bearing seat, which is disposed on the upper side of the door frame. A threaded rod is disposed inside the bearing seat, and an anti-detachment plate is disposed at the bottom end of the threaded rod. A movable plate is threadedly sleeved on the outer side of the threaded rod, and a gate is welded to one side of the movable plate.

[0018] Through the above technical solution, the bearing seat is fixedly installed on the upper side of the door frame, providing rotational support for the threaded rod, allowing the threaded rod to rotate stably around its own axis; the threaded rod and the movable plate are connected by a threaded sleeve, and when the threaded rod is rotated, the threaded transmission converts the rotational motion of the threaded rod into the vertical linear motion of the movable plate, which in turn drives the gate plate, which is welded and fixed to it, to move up and down synchronously, realizing the opening and closing of the passage inside the door frame and the adjustment of the opening size; the anti-detachment plate at the bottom of the threaded rod can prevent the movable plate from falling off the bottom of the threaded rod, ensuring the safe operation of the structure.

[0019] The threaded drive features smooth transmission and high precision, enabling precise positioning of the gate and ensuring accurate adjustment of the discharge volume. The anti-detachment plate prevents device malfunctions caused by the movement plate falling off, improving structural safety. The overall components are firmly connected, have strong load-bearing capacity, can adapt to the pressure during grain conveying, and extend the service life of the components.

[0020] Preferably, the second gate component includes a mounting plate, which is disposed on one side of the door frame. Several bolts are disposed on the upper side of the mounting plate, which passes through the upper side of the door frame. Nuts are threaded to the outer side of the bolts. A cylinder is disposed on one side of the mounting plate. An air supply component is connected to one side of the cylinder through a conduit. A second movable plate is disposed on the shaft end of the cylinder. A second gate is welded to one side of the second movable plate.

[0021] Through the above technical solution, the mounting plate is fixed to one side of the door frame by bolts and nuts, realizing a stable connection between the second gate plate and the door frame; the air supply component provides compressed gas to the cylinder through the conduit, and the cylinder drives the shaft end to make telescopic movements under the action of gas pressure. The cylinder shaft end drives the movable plate two connected to it to move left and right synchronously, and the movable plate two in turn drives the welded and fixed gate plate two to move left and right, ultimately realizing the opening and closing of the grain channel and the control of the discharge volume in the door frame.

[0022] The pneumatic drive has a fast response speed, which can quickly open and close the second gate, improving the efficiency of material discharge control and making it suitable for scenarios that require frequent switching of material discharge status. The bolt and nut fixing method makes disassembly convenient, facilitating the maintenance and replacement of components such as cylinders and second gates in the future. The air supply and cylinder have stable power, and the pneumatic system has a simple structure and low failure rate, reducing the operation and maintenance cost of the device, while also being able to adapt to the dusty working conditions of grain storage environment.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by installing a vibrating component on the outside of the discharge pipe, can proactively prevent grain from caking and accumulating inside the pipe, thus preventing blockages and ensuring a continuous and uninterrupted grain conveying process. This significantly reduces the workload and time cost of manually clearing blockages. At the same time, the gate component at the end of the discharge pipe can flexibly control the start and stop of discharge and the discharge speed, adapting to the needs of different scenarios such as subsequent grain storage and processing. This improves the versatility and operational flexibility of the entire grain pit device and effectively reduces losses during grain conveying.

[0024] In this invention, the vibratory motor, as a mature vibration source component, has a stable and controllable vibration frequency and amplitude, which can accurately apply effective vibration to the discharge pipe. Compared with other vibration structures, it has a more reliable anti-clogging effect. Moreover, the vibratory motor is small in size and easy to install, requiring no complex modification to the discharge pipe, and its maintenance and replacement are easy. In addition, the vibratory motor has low energy consumption, which can reduce the overall operating energy consumption of the device while achieving the anti-clogging function, meeting the requirements of energy-saving production, and reducing energy cost investment in the long term.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: A grain trough anti-clogging device includes a grain trough 1, a discharge pipe 2, a vibrating element, and a gate 4. The discharge pipe 2 is connected to one side of the grain trough 1 and is used to transport grain outward. The vibrating element is installed on the outside of the discharge pipe 2 and is used to apply vibration to the discharge pipe 2 to prevent grain from clogging inside the pipe. The gate 4 is located at the end of the discharge pipe 2 away from the grain trough 1 and is used to control the opening and closing of the discharge pipe.

[0030] The grain pit 1 includes a grain storage shell 11, a filter grid 12, and an inclined guide plate 13. The grain storage shell 11 is usually welded from steel plates and has a box structure with an open top. The filter grid 12 is fixedly installed on the upper edge of the grain storage shell 11 by bolts and is used to screen out large impurities when the grain enters. The inclined guide plate 13 is welded and fixed to the bottom of the inner cavity of the grain storage shell 11, and its inclination angle is preferably 30° to 45°, so that the grain can converge at the inlet of the discharge pipe 2 under the action of gravity.

[0031] The vibrating component uses a vibrating motor 3, which is fixedly connected to the middle of the outer wall of the discharge pipe 2. When the vibrating motor 3 is working, the high-frequency vibration generated is directly transmitted to the discharge pipe 2, causing the pipe wall to vibrate periodically and slightly, thereby effectively breaking the bridging or adhesion of grain in the pipe and ensuring the smooth flow of grain. The model of the vibrating motor 3 can be selected according to the size of the discharge pipe 2 and the characteristics of the grain. Its power cord is led out through a waterproof connector and connected to the external control system.

[0032] The gate component 4 includes a gate frame 41, a first gate plate component 42, and a second gate plate component 43. The gate frame 41 is a rectangular frame structure, which is fixedly connected to the outlet end of the discharge pipe 2 through a flange.

[0033] The first gate component 42 includes a bearing seat 421, a threaded rod 422, an anti-detachment plate 423, a movable plate 424, and a gate 425. The bearing seat 421 is fixed to the top outer side of the door frame 41 by bolts. The threaded rod 422 is rotatably installed in the bearing seat 421 through a bearing, and its top end can be connected to a handwheel or an electric drive device. The anti-detachment plate 423 is welded to the bottom end of the threaded rod 422. The movable plate 424 has a threaded hole in the center that matches the threaded rod 422. By rotating the threaded rod 422, the movable plate 424 can be driven to move vertically. The gate 425 is welded to the side of the movable plate 424 near the door frame 41, and its size is adapted to the internal channel of the door frame 41 to achieve initial flow control.

[0034] The second gate component 43 includes a mounting plate 431, bolts 432, nuts 433, a cylinder 434, an air supply component 435, a second movable plate 436, and a second gate 437. The mounting plate 431 is fixed to the side of the door frame 41 by multiple bolts 432 and nuts 433. The cylinder 434 is hinged to the mounting plate 431 by a pin, and its air inlet is connected to the air supply component 435 through a high-pressure hose. The second movable plate 436 is fixedly connected to the piston rod end of the cylinder 434. The second gate 437 is welded to the side of the second movable plate 436 near the door frame 41 and is also adapted to the internal channel of the door frame 41. By controlling the extension and retraction of the cylinder 434, the second gate 437 can be driven to open and close quickly to achieve secondary sealing or flow regulation of the discharge.

[0035] The workflow of this embodiment is as follows: Grain first falls into the grain storage shell 11 of the lower grain pit 1 through the filter grid 12, and slides along the inclined guide plate 13 to the inlet of the discharge pipe 2. The vibration motor 3 is started, and the discharge pipe 2 keeps the grain flowing under the action of vibration. When discharge is required, the opening is first roughly adjusted by the first gate component 42, and then the opening and closing of the gate is precisely controlled by the cylinder 434 of the second gate component 43 to achieve orderly discharge. The double gate design not only ensures the reliability of sealing, but also realizes the flexible control of flow.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
