Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, and particularly to a silent component of a grain feeding and conveying pipeline. Background Art

[0002] In the grain processing and transportation industry, as a key device connecting various links, the operation efficiency and noise control level of the grain feeding and conveying pipeline have an important impact on the overall production environment and efficiency. During the process of grain falling, the conveying pipeline often generates relatively large noise, which not only affects the comfort of the working environment, but also may cause damage to the equipment itself, shortening its service life. Therefore, a silent component of the grain feeding and conveying pipeline is needed.

[0003] When the grain falls through the conveying pipeline into the receiving container, due to the relatively high speed and concentrated mass, significant impact sound will be generated. This impact sound not only has a high volume, but also a high frequency and a wide propagation range, causing adverse effects on the surrounding environment and personnel. At present, the noise reduction technologies on the market mostly focus on the overall sound insulation treatment of the pipeline, such as installing a sound insulation cover and using sound insulation materials. However, these methods have limited noise reduction effects on the impact sound of the falling grain, and often cannot effectively control the impact sound source directly, resulting in the noise problem being difficult to be fundamentally solved, and there are certain deficiencies. For this reason, we provide a silent component of the grain feeding and conveying pipeline to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a silent component of the grain feeding and conveying pipeline.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A silent component of a grain feeding and conveying pipeline, including a limiting shell, the top of the limiting shell is fixedly communicated with a conveying pipeline, the inner wall of the conveying pipeline is fixedly connected with a rubber layer, the inner wall of the limiting shell is provided with a sound insulation layer, a limiting mechanism is arranged inside the limiting shell, a buffer mechanism is arranged inside the limiting shell, a bearing plate is arranged inside the limiting shell, a buffer pad is arranged inside the limiting shell, the buffer pad is fixedly connected with the bearing plate, and the buffer mechanism is located at the bottom of the bearing plate.

[0006] Preferably, the limiting mechanism includes a limiting shaft, and the outer surface of the limiting shaft rotates with the inner wall of the limiting shell. A retaining piece is fixedly connected to both ends of the limiting shaft, and the upper end of the bearing plate is fixedly connected with the limiting shaft.

[0007] Preferably, a torsion spring is sleeved on each of the two outer ends of the limiting shaft. One end of the torsion spring is fixedly connected with the outer surface of the limiting shell, and the other end of the torsion spring is fixedly connected with the outer surface of the retaining piece.

[0008] Preferably, the buffer mechanism includes a limit cylinder, and the limit cylinder is fixedly connected to the limit housing. An activity cavity is provided inside the limit cylinder.

[0009] Preferably, a moving piece is slidably connected to the inner wall of the activity cavity. One end of the moving piece is fixedly connected to a moving column, and the end of the moving column away from the moving piece abuts against the bottom of the bearing plate.

[0010] Preferably, the other end of the moving piece is fixedly connected to an elastic member, and the end of the elastic member away from the moving piece is fixedly connected to the inner wall of the activity cavity.

[0011] Preferably, the elastic member is a compression spring.

[0012] Beneficial effects:

[0013] Compared with the prior art, the soundproof component of the grain feeding and conveying pipeline has the following beneficial effects:

[0014] First, by setting the bearing plate and the buffer pad, the present invention can temporarily carry and initially buffer the grains falling from the conveying pipeline. By setting the limit mechanism, the bearing plate and the buffer pad can be guided and limited. By setting the buffer mechanism, the impact force of the grains on the bearing plate and the buffer pad can be buffered and depressurized. Through the mutual cooperation of the bearing plate, the buffer pad, the limit mechanism and the buffer mechanism, the impact sound generated when the grains in the conveying pipeline fall into the receiving container can be effectively reduced in noise, and the impact sound source can be effectively controlled directly, and the soundproof effect is better.

[0015] Second, by the rotation of the limit shaft, the present invention can drive the baffles at both ends of the limit shaft to rotate accordingly. At this time, the baffle will drive the torsion spring to undergo elastic deformation, and at the same time, the torsion spring will generate a reverse acting force on the baffle. When the baffle is released, the torsion spring will drive the baffle to rotate in the reverse direction, and then drive the limit shaft to rotate accordingly, thus realizing the rapid reset effect of the limit shaft.

[0021] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] See Figures 1 to 4 , a soundproof component of a grain feeding and conveying pipe, including a limit shell 1. The top of the limit shell 1 is fixedly communicated with a conveyor pipe 2, and the inner wall of the conveyor pipe 2 is fixedly connected with a rubber layer 3.

[0023] The rubber layer 3 is arranged in the conveyor pipe 2 and can reduce the collision sound of the grain in the conveyor pipe 2 against the pipe wall of the conveyor pipe 2, thereby achieving a sound insulation effect.

[0024] The inner wall of the limit shell 1 is provided with a sound insulation layer 4. The sound insulation layer 4 is made of microcellular foam and can effectively absorb and weaken the transmission of noise.

[0025] A limiting mechanism 5 is arranged inside the limit shell 1. The limiting mechanism 5 includes a limiting shaft 501, and the upper end of the bearing plate 7 is fixedly connected with the limiting shaft 501. And the outer surface of the limiting shaft 501 rotates with the inner wall of the limit shell 1. A flap 502 is fixedly connected to both ends of the limiting shaft 501. A torsion spring 503 is sleeved on each of the two outer ends of the limiting shaft 501. The torsion spring 503 belongs to a helical spring, and its end is fixed to the flap 502 and the outer surface of the limit shell 1. When the limiting shaft 501 rotates around the center of the torsion spring 503, the torsion spring 503 pulls them back to the initial position, generating torque or rotational force. One end of the torsion spring 503 is fixedly connected to the outer surface of the limit shell 1, and the other end of the torsion spring 503 is fixedly connected to the outer surface of the flap 502.

[0026] By rotating the limiting shaft 501, the flaps 502 at both ends of the limiting shaft 501 can be driven to rotate accordingly. At this time, the flap 502 will drive the torsion spring 503 to undergo elastic deformation, and at the same time, the torsion spring 503 will generate a reverse acting force on the flap 502. When the flap 502 is released, the torsion spring 503 will drive the flap 502 to rotate in the reverse direction, thereby driving the limiting shaft 501 to rotate accordingly, thus achieving the effect of quickly resetting the limiting shaft 501.

[0027] Inside the limiting shell 1, a buffer mechanism 6 is provided. The buffer mechanism 6 includes a limiting cylinder 601, and the limiting cylinder 601 is fixedly connected to the limiting shell 1. An activity cavity 602 is opened inside the limiting cylinder 601. A moving piece 603 is slidably connected to the inner wall of the activity cavity 602. One end of the moving piece 603 is fixedly connected to a moving column 604, and the end of the moving column 604 away from the moving piece 603 abuts against the bottom of the bearing plate 7. The other end of the moving piece 603 is fixedly connected to an elastic member 605, and the end of the elastic member 605 away from the moving piece 603 is fixedly connected to the inner wall of the activity cavity 602.

[0028] The elastic member 605 is made of a spring. When a force is applied, it deforms and stores a certain amount of elastic potential energy. When the force disappears, it releases the elastic potential energy and gradually restores its deformation, so that a linear and rapid reset movement of the object can be realized.

[0029] A bearing plate 7 is arranged inside the limiting shell 1. The bearing plate 7 is made of a porous sound-absorbing plate, which can absorb and weaken the propagation of noise. A buffer pad 8 is arranged inside the limiting shell 1, and the outer surface of the buffer pad 8 is fixedly connected to the outer surface of the bearing plate 7. The buffer pad 8 is a rubber pad, which can reduce the impact force and noise when the grain falls.

[0030] After the bearing plate 7 and the buffer pad 8 are impacted by the grain, a pressure will be generated on the moving column 604, causing the moving column 604 to drive the moving piece 603 to penetrate into the activity cavity 602, and the elastic member 605 will be squeezed. At this time, the elastic member 605 will undergo elastic deformation and generate a reverse thrust, thereby being able to buffer and relieve the impact force from the moving piece 603 and the moving column 604, and thus being able to buffer and relieve the impact force of the grain on the bearing plate 7 and the buffer pad 8.

[0031] Working principle: When the utility model is in use, first, when the grain falls to the receiving container through the conveying pipeline 2, it will first come into contact with the buffer pad 8. At this time, the buffer pad 8 can initially buffer the falling grain and can also play a noise reduction effect. Then, the impact force of the grain will drive the bearing plate 7 and the buffer pad 8 to rotate around the limit shaft 501. At the same time, it can drive the limit shaft 501 and the retaining pieces 502 at both ends of it to rotate. At this time, the retaining piece 502 will drive the torsion spring 503 to undergo elastic deformation, and at the same time, the torsion spring 503 will generate an opposite acting force on the retaining piece 502, thereby being able to buffer the impact force generated by the grain on the bearing plate 7 and the buffer pad 8, and thus being able to achieve a noise reduction effect. When the impact force on the bearing plate 7 and the buffer pad 8 weakens, the torsion spring 503 will drive the retaining piece 502 to rotate in the reverse direction, and thus be able to drive the limit shaft 501, the bearing plate 7 and the buffer pad 8 to rotate accordingly, thereby realizing the rapid reset effect of the bearing plate 7 and the buffer pad 8. At the same time, after the bearing plate 7 and the buffer pad 8 are impacted by the grain, they will exert a pressure on the moving column 604, causing the moving column 604 to drive the moving piece 603 to penetrate into the moving cavity 602 and squeeze the elastic member 605. At this time, the elastic member 605 will undergo elastic deformation and generate a reverse thrust, thereby being able to buffer and relieve the impact force from the moving piece 603 and the moving column 604, and thus being able to buffer and relieve the impact force of the grain on the bearing plate 7 and the buffer pad 8. By the mutual cooperation of the bearing plate 7, the buffer pad 8, the limiting mechanism 5 and the buffer mechanism 6, it is possible to effectively reduce the impact noise generated when the grain in the conveying pipeline 2 falls to the receiving container, and it can directly and effectively control the impact sound source, and the sound insulation effect is better.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
