Description

Technical Field

[0001] This utility model relates to the field of material feeding equipment technology, and in particular to an anti-blocking material feeding device for a silo. Background Technology

[0002] A silo is a common type of storage equipment, serving functions such as intermediate storage, material buffering, and proportional discharge. In practical use, materials are discharged from the bottom of the silo through a cone-shaped discharge port, which can easily cause blockages. When blockages occur, workers typically use steel pipes to poke the material from bottom to top, loosening the blockage and allowing the material to fall smoothly. Besides manual pokes, there are also vibratory discharge devices. These devices work by vibrating the sidewalls of the silo, which in turn vibrate the material in contact with them, changing the mechanical structure between the materials and thus relieving the blockage. However, vibratory discharge devices have limited effectiveness, only vibrating the material near the silo wall, and the excessive noise from the vibrator causes significant noise pollution to the surrounding environment.

[0003] CN216637577U discloses a material discharge anti-blocking device suitable for silos, comprising a discharge cylinder, a swirling mechanism, a rotating mechanism, a rotating rod mechanism, a first motor, a drive mechanism, a connecting plate, a PLC, and a protective cover; the upper end of the discharge cylinder is connected to the discharge port of the silo; the rotating mechanism is disposed inside the discharge cylinder; the rotating rod mechanism is disposed inside the rotating mechanism, and the top end of the rotating rod mechanism is connected to the swirling mechanism; the connecting plate is disposed at the bottom end of the discharge cylinder, and the first motor, drive mechanism, and protective cover are all disposed on the connecting plate, with the first motor and drive mechanism located within the cavity enclosed by the protective cover; the... The motor is connected to the rotating rod mechanism; the drive mechanism is connected to the rotating material mechanism. This device improves the efficiency of clearing blockages and reduces the labor intensity of workers. However, its drawback is that the stirring mechanism is not easy to replace and disassemble, and the fixed stirring bar cannot be flexibly replaced. It is easy to have poor clearing effect on specific materials. When the stirring bar is worn, deformed or has material residue that is difficult to clean due to long-term use, the maintenance difficulty is increased. The entire equipment needs to be disassembled for replacement or cleaning. Incomplete cleaning may lead to residual material clumping, which will affect the smoothness of subsequent material discharge and the service life of the equipment. Therefore, an anti-blocking material discharge device for silos is needed. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an anti-blocking feeding device for a silo, wherein:

[0028] The feeding cylinder 1 serves as the main frame of the device. Multiple supports 2 are evenly distributed inside the cylinder and are tightly fixed to the cylinder wall. The ends of the supports 2 are connected to the threaded cylinder 4 and are placed firmly in the center of the feeding cylinder 1. This symmetrically distributed support structure disperses the weight of the upper components. The selection of steel material significantly improves the overall load-bearing capacity and ensures that it is not easily deformed during long-term use.

[0029] The motor 5 is firmly fixed to the bottom of the feed cylinder 1 by the motor bracket 3. The motor bracket 3 is made of thickened steel plate, which effectively reduces the vibration transmission during motor operation. The output end of the motor 5 is rigidly connected to the rotating part 6. The rectangular rod 7 at the top of the rotating part 6 is precisely embedded in the rectangular groove inside the threaded rod 8 to form a reliable torque transmission structure, ensuring that the motor power is efficiently transmitted to the threaded rod 8.

[0030] The threads on the outer surface of the threaded rod 8 precisely mesh with the threads on the inner wall of the threaded cylinder 4. The thread accuracy is controlled at a high level to reduce jamming. The top of the threaded rod 8 is fastened to the rotating disk 9 by bolts. When the threaded rod 8 is driven to rotate, it moves axially up and down under the side effect of the threads, driving the rotating disk 9 to complete the rotation and lifting actions at the same time, thus expanding the space range of the mixing operation.

[0031] The top of the rotating disk 9 is machined with a smooth guide surface, and the bottom of the mounting disk 10 fits against it to achieve smooth sliding. The grooves 13 arranged in a circular array on the surface of the mounting disk 10 match the shape of the locking blocks 14 inside the rotating disk 9. The spring 15 connected to the rear end of the locking block 14 is in a pre-compressed state, always applying a forward thrust to the locking block 14 to ensure that the locking block 14 and the grooves 13 are tightly engaged in the non-disassembled state, and to prevent the mounting disk 10 from becoming loose.

[0032] The round rod 16 at the bottom of the locking block 14 extends vertically downward, and its end is machined into an arc shape to reduce friction with the arc groove 18. The rotating assembly 17 is mounted on the bottom of the rotating disk 9 through a bearing to achieve flexible rotation. The arc groove 18 is designed as a curved structure with a gradually changing curvature. When the rotating assembly 17 rotates, the inner wall of the arc groove 18 pushes the round rod 16 to move laterally, which drives the locking block 14 to compress the spring 15 to retract and disengage from the locking groove 13.

[0033] Multiple handles 19 on the surface of the rotating component 17 are symmetrically distributed, making it convenient for operators to apply force to rotate from different angles. The stirring component base 11 on the top of the mounting plate 10 is fixed to the mounting plate 10 by welding. The stirring component 12 is connected to the base by bolts. The paddle-type stirring head 20 is suitable for materials with good flowability, while the conical stirring head 21 is more suitable for crushing blocky materials. The diversified selection improves the applicability of the device.

[0034] Working principle: When the anti-clogging feeding device is working in this silo, the motor 5 is fixed to the bottom of the feeding cylinder 1 via the motor bracket 3, driving the rotating part 6 to rotate, which in turn drives the top rectangular rod 7 to rotate. The rectangular rod 7 is slidably connected to the rectangular groove inside the threaded rod 8, so that the threaded rod 8 rotates synchronously. Since the threaded rod 8 is threadedly connected to the threaded cylinder 4, it moves axially during rotation, which in turn drives the rotating disk 9 to move up and down and rotate synchronously. The mounting disk 10 rotates with the rotating disk 9, and the stirring component 12 fixed on it moves accordingly, stirring and preventing clogging. When replacing the stirring component, turn the handle 19 to drive the rotating component 17 to rotate. The arc groove 18 pushes the round rod 16, so that the clamping block 14 compresses the spring 15 and can disengage from the slot 13, and the mounting disk 10 can be removed. During installation, the inclined surface on the clamping block 14 can automatically compress the spring and make the clamping block 14 lock into the slot 13, which is convenient to operate.

[0035] Example 1:

[0036] When processing free-flowing powdery materials, the top of the mounting plate 10 is fixed with a paddle-type mixing head 20 via the mixing component base 11. The paddle-type structure can smoothly propel the material flow and reduce dust.

[0037] If it is necessary to switch to processing blocky materials, the operator holds the handle 19 on the surface of the rotating component 17 and rotates it. The arc groove 18 pushes the round rod 16 to drive the locking block 14 to compress the spring 15, so that the locking block 14 disengages from the locking groove 13 of the mounting plate 10 and the mounting plate 10 with the paddle-type stirring head 20 is removed.

[0038] Place the mounting plate 10 with the conical stirring head 21 on the sliding surface of the top of the rotating plate 9. After releasing the handle 19, the spring 15 returns to its original position and pushes the locking block 14 into the slot 13 of the new mounting plate 10, thus completing the replacement of the stirring assembly 12. The conical stirring head 21 can effectively break up lumpy materials to avoid clogging.

[0039] After the replacement is completed, start motor 5. Power is transmitted to threaded rod 8 through rotating part 6 and rectangular rod 7. Threaded rod 8 rotates in threaded cylinder 4 and drives rotating disk 9, mounting disk 10 and conical stirring head 21 to rotate up and down to meet the anti-clogging requirements of lumpy materials.

[0040] Example 2:

[0041] The threaded cylinder 4 not only provides threaded engagement for the threaded rod 8 to achieve lifting and lowering, but its structure, which is fixed to the feed cylinder 1 by the bracket 2, also plays a central positioning role, ensuring that the threaded rod 8 and the upper stirring component always move along the central axis of the feed cylinder 1, and avoids deviation and collision with the cylinder wall.

[0042] The sliding fit between the rectangular rod 7 and the internal rectangular groove of the threaded rod 8 not only transmits the rotational power of the motor 5 to make the threaded rod 8 rotate synchronously, but also allows the threaded rod 8 to move freely along the axial direction during rotation, realizing the coordination of rotation and lifting actions and ensuring uninterrupted power transmission.

[0043] Under normal conditions, the spring 15 pushes the locking block 14 into the slot 13 to ensure a stable connection between the mounting plate 10 and the rotating plate 9. When the stirring component 12 is replaced, the spring 15 can be compressed to disengage the locking block 14 from the slot 13. The connection and separation are switched through elastic deformation, which improves the ease of operation.

[0044] When the rotating component 17 rotates, the arc-shaped groove 18 on its surface pushes the locking block 14 to move through contact with the round rod 16, converting the operator's rotational force into the lateral extension force of the locking block 14. This allows the mixing component to be disassembled and assembled without complicated tools, simplifying the maintenance process.

[0045] Example 3:

[0046] When processing granular materials such as rice in a grain processing scenario, a paddle-type mixing head 20 is installed on the mounting plate 10. After starting the motor 5, the threaded rod 8 drives the rotating plate 9, the mounting plate 10 and the paddle-type mixing head 20 to rotate slowly and rise and fall slightly, gently pushing the rice to flow, avoiding grain breakage, and preventing the rice from arching and blocking in the material cylinder.

[0047] By observing the feeding process, if the operator finds a slight blockage, they can adjust the rotation speed of the mixing head by controlling the motor speed to accelerate the flow of materials in that area. This can alleviate the blockage problem without stopping the machine and ensure continuous and stable grain feeding.

[0048] When handling hard materials such as sand and gravel in construction scenarios, a conical mixing head 21 is used. After starting the motor 5, the rotation speed of the threaded rod 8 is increased and the lifting range is increased. The conical mixing head 21 rotates at high speed to impact the agglomerated sand and gravel, while moving up and down the blockage structure inside the crushing cylinder to adapt to the characteristics of sand and gravel materials that are hard and easy to accumulate.

[0049] When sand and gravel have high moisture content and become stuck, the rotating assembly 17 can be quickly replaced with a larger paddle-type mixing head 20 by turning the handle 19. The wide paddles scrape the stuck material on the cylinder wall, and the high-speed rotation breaks up the stuck clumps, ensuring smooth sand and gravel feeding.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
