Description

Technical Field

[0001] This utility model relates to the field of aggregate bin unloading technology, and in particular to an anti-clogging vibration mechanism for aggregate bin unloading ports. Background Technology

[0002] The main function of aggregate bin unloading is to transport and discharge aggregates, thereby transferring the aggregates inside the bin. During the unloading process, an anti-clogging vibration mechanism is required to break the static friction of the material through active vibration or passive impact, thus facilitating the unloading operation.

[0003] Existing anti-clogging vibration mechanisms for aggregate bin discharge ports generally require drive equipment. The motor, pneumatic or hydraulic system needs continuous power supply or energy supply. Long-term operation results in high energy consumption, and the equipment purchase and maintenance costs are also high. For low-flow, intermittent discharge or small-scale scenarios, this leads to resource waste. Furthermore, during vibration, the connection between the anti-clogging vibration mechanism and the aggregate bin discharge port area is prone to loosening.

[0004] Therefore, in response to the problem that the connection between the anti-blocking vibration mechanism and the aggregate bin discharge port area is prone to loosening during vibration, this utility model uses a combination strip plate to perform telescopic buffering through a support shaft and spring body, thereby reducing vibration between the mounting plate and the combination strip plate and the combination square plate, facilitating the fixed installation of the mounting plate and the aggregate bin discharge port, and at the same time, the guide vibration plate can be replaced to adapt to aggregate bin discharge ports of different sizes. Utility Model Content

[0005] In order to overcome the problem that common anti-clogging vibration mechanisms for aggregate bin discharge ports are prone to loosening during vibration, the connection between the anti-clogging vibration mechanism and the aggregate bin discharge port area is easily loosened.

[0006] The technical solution of this utility model is as follows: a vibration mechanism for preventing blockage at the discharge port of an aggregate bin, comprising a guide vibration plate; a guide arc groove is provided on the upper surface of the guide vibration plate, and a fixed column is fixedly installed on the lower surface of the guide vibration plate; a connecting shaft is provided at the center of the bottom surface of the fixed column, and the connecting shaft passes through the combined square plate; a first rubber spring is sleeved around the outer side of the connecting shaft, and the first rubber spring is located between the fixed column and the combined square plate; a stud is provided at the center of the bottom surface of the connecting shaft, and a second rubber spring is sleeved around the outer side of the stud; an adjusting nut is threaded on the outer side of the bottom end of the stud, and the adjusting nut is located below the second rubber spring.

[0007] Preferably, the connecting shaft, the fixed column, and the stud are integrated into a single structure, the fixed columns are symmetrically distributed on the guide vibration plate, and the connection between the connecting shaft and the combined square plate is a sliding connection.

[0008] Preferably, the diameter of the stud is smaller than the diameter of the connecting shaft, and the diameter of the connecting shaft is smaller than the diameter of the fixing post. The diameter of the fixing post is larger than the outer diameter of the first rubber spring and the second rubber spring, and the inner diameter of the first rubber spring and the second rubber spring is larger than the diameter of the connecting shaft.

[0009] Preferably, the adjusting nut has a limiting hole on its side frame, and an elastic limiting rod is installed between the adjusting nuts, with the end of the elastic limiting rod located inside the limiting hole. The circumferential diameter of the adjusting nut is greater than the outer diameter of the second rubber spring.

[0010] Preferably, the elastic limiting rod and the limiting hole are connected by a snap-fit ​​connection, and the outer side of the end of the elastic limiting rod is chamfered, and the limiting holes are evenly distributed on the adjusting nut.

[0011] Preferably, a combined strip is fixedly installed at the rear center of the combined square plate, and the combined strip is located inside the storage groove. The storage groove is opened through the bottom end of the mounting plate. A support shaft is installed inside the storage groove, and the support shaft passes through the combined strip. The end of the support shaft is fixedly connected to the inner wall of the mounting plate. A spring body is installed around the outside of the support shaft, and the spring body is located on the upper and lower sides of the combined strip.

[0012] Preferably, the length of the combined strip is less than the length of the storage groove, and the connection between the combined strip and the support shaft is a sliding connection, and the support shaft is symmetrically distributed on the combined strip and the mounting plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. The guide vibration plate can be installed on the combined square plate through the fixed column, connecting shaft and stud. Subsequently, the first rubber spring, the second rubber spring and the adjusting nut are used for combined support to maintain stability. The guide vibration plate can be flexibly replaced and matched according to the size of the aggregate bin discharge port. At the same time, the rotation of the adjusting nut on the stud causes the first rubber spring and the second rubber spring to be compressed under force, thereby adjusting the overall extension range of the first rubber spring and the second rubber spring.

[0015] 2. The adjusting nut is connected to the stud by a thread, which facilitates disassembly and assembly. At the same time, when the adjusting nut is installed on the stud, the engagement between the upper limit hole of the adjusting nut and the elastic limit rod can prevent the adjusting nut from rotating and loosening on the stud, thus maintaining the stability of operation.

[0016] 3. The guide vibrating plate can impact the aggregate as it falls on the combined square plate. The impact force compresses the first rubber spring, and then the spring rebounds, causing the guide vibrating plate to vibrate back and forth. The vibration is transmitted to the discharge port through the guide vibrating plate, breaking up the material arching. The whole system does not require external power and relies entirely on the impact force of the material flow. It is suitable for scenarios without power supply or low maintenance. It can be used for small-scale, low-discharge-speed silos and low-viscosity, high-flow-rate aggregates.

[0017] 4. The guide vibrating plate vibrates up and down through impact and the first and second rubber springs. The overall force can drive the combined square plate to move up and down on the guide vibrating plate through the combined strip plate, thereby performing vibration reduction work, reducing the impact of vibration unloading process, and reducing the impact of fixed installation of the mounting plate and the aggregate bin unloading port area.

[0024] 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.

[0025] Please see Figures 1-5This utility model provides a technical solution: a vibration mechanism for preventing blockage at the discharge port of an aggregate bin, including a guide vibration plate 1; a guide arc groove 2 is provided on the upper surface of the guide vibration plate 1, and a fixed column 3 is fixedly installed on the lower surface of the guide vibration plate 1; a connecting shaft 4 is provided at the center of the bottom surface of the fixed column 3, and the connecting shaft 4 passes through a combined square plate 5; a first rubber spring 6 is sleeved around the outside of the connecting shaft 4, and the first rubber spring 6 is located between the fixed column 3 and the combined square plate 5; a stud 7 is provided at the center of the bottom surface of the connecting shaft 4, and a second rubber spring 8 is installed around the outside of the stud 7; an adjusting nut 9 is threaded on the outside of the bottom end of the stud 7, and the adjusting nut 9 is located below the second rubber spring 8.

[0026] The connecting shaft 4 is integrated with the fixed column 3 and the stud 7. The fixed column 3 is symmetrically distributed on the guide vibration plate 1. The connection between the connecting shaft 4 and the combined square plate 5 is a sliding connection, which allows the guide vibration plate 1 to slide on the combined square plate 5 through the fixed column 3 and the connecting shaft 4. The symmetrically distributed fixed column 3 and connecting shaft 4 can maintain the stability of the guide vibration plate 1 during operation.

[0027] The diameter of the stud 7 is smaller than the diameter of the connecting shaft 4, and the diameter of the connecting shaft 4 is smaller than the diameter of the fixing post 3. The diameter of the fixing post 3 is larger than the outer diameter of the first rubber spring 6 and the second rubber spring 8, and the inner diameter of the first rubber spring 6 and the second rubber spring 8 is larger than the diameter of the connecting shaft 4. Based on the diameters of the stud 7, the connecting shaft 4, and the fixing post 3, it is beneficial to assemble and connect the first rubber spring 6 and the second rubber spring 8, and facilitate the subsequent operation of the first rubber spring 6 and the second rubber spring 8 under pressure.

[0028] The adjusting nut 9 has a limiting hole 10 on its side frame, and an elastic limiting rod 11 is installed between the adjusting nuts 9. The end of the elastic limiting rod 11 is located inside the limiting hole 10. The circumferential diameter of the adjusting nut 9 is larger than the outer diameter of the second rubber spring 8. The elastic limiting rod 11 is connected to the limiting hole 10 by a snap-fit ​​connection. The outer side of the end of the elastic limiting rod 11 is chamfered. The limiting holes 10 are evenly distributed on the adjusting nut 9. The second rubber spring 8 can be squeezed by rotating the adjusting nut 9, which facilitates the adjustment of the extension range of the first rubber spring 6 and the second rubber spring 8. After the adjusting nut 9 is adjusted, the position of the adjusting nut 9 can be fixed by the engagement of the elastic limiting rod 11 with the limiting hole 10, preventing the nut 9 from rotating and loosening due to vibration.

[0029] A combined strip plate 12 is fixedly installed at the rear center of the combined square plate 5, and the combined strip plate 12 is located inside the receiving groove 13. The receiving groove 13 is opened through the bottom end of the mounting plate 14. A support shaft 15 is installed inside the receiving groove 13, and the support shaft 15 passes through the combined strip plate 12. The end of the support shaft 15 is fixedly connected to the inner wall of the mounting plate 14. A spring body 16 is installed around the outside of the support shaft 15, and the spring body 16 is located on the upper and lower sides of the combined strip plate 12. The length of the combined strip plate 12 is less than the length of the receiving groove 13. The combined strip plate 12 and the support shaft 15 are connected by a sliding connection. The support shaft 15 is symmetrically distributed on the combined strip plate 12 and the mounting plate 14. When the guide vibration plate 1 above the combined square plate 5 is impacted by the falling aggregate, it compresses the first rubber spring 6 to perform vibration and anti-blocking work. The overall vibration is reduced by the up and down movement of the combined strip plate 12 on the mounting plate 14, reducing the impact of the mounting plate 14 on the aggregate bin discharge port area.

[0030] Working principle: According to Figure 1 Subsequently, the mounting plate 14 can be fixed to the aggregate bin discharge port area using bolts, fasteners, and slots. At the same time, the mounting plate 14 can be used to move the combined square plate 5 in advance, and the guide vibration plate 1 above the combined square plate 5 can be moved to a suitable position below the aggregate bin discharge port to facilitate subsequent unloading guidance.

[0031] according to Figures 1-3 and Figure 5 When the aggregate bin discharge port is opened, the aggregate can fall and impact the guide vibration plate 1. The guide vibration plate 1 is subjected to impact force, which can squeeze the first rubber spring 6 on the outside of the connecting shaft 4 through the fixed column 3. At the same time, the connecting shaft 4 drives the stud 7, the second rubber spring 8 and the adjusting nut 9 to move up and down slightly, thereby causing the guide vibration plate 1 to reciprocate. The aggregate is discharged through the guide arc groove 2 on the guide vibration plate 1 and the inclined structure of the guide vibration plate 1. During the reciprocating vibration, the position of the adjusting nut 9 on the stud 7 can be kept stable by the engagement of the elastic limit rod 11 and the limit hole 10 to avoid rotational loosening.

[0032] according to Figure 2 and Figure 4 When the guide vibrating plate 1 reciprocates, it can drive the combined square plate 5 to vibrate. The combined square plate 5 can perform vibration reduction by sliding the combined strip plate 12 up and down in the storage groove 13. The combined strip plate 12 maintains the stability of sliding according to the support shaft 15. At the same time, the combined strip plate 12 swings up and down repeatedly according to the spring body 16 to avoid collision between the combined strip plate 12 and the connecting shaft 4, thereby reducing the impact of the fixed installation of the mounting plate 14 and the aggregate bin discharge port area.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
