Description

Technical Field

[0001] The utility model relates to the technical field of cold bins, in particular to a cold bin with an anti-blocking structure. Background Art

[0002] Cold bins are widely used in asphalt production. Adjusting the slope of the sieve plate of the cold bin is the key to ensuring the fluidity of materials and the screening efficiency. The adjustment of the sieve plate slope mainly affects the flow rate of materials on the sieve plate and the screening effect. Generally speaking, increasing the sieve plate slope can accelerate the flow rate of materials and reduce the screening time.

[0003] Chinese Patent with publication number CN211099287U discloses a granular asphalt screening device, which includes a housing, a crushing cylinder and a motor. The top surface of the crushing cylinder is fixedly communicated with a feed pipe. The inner top wall of the crushing cylinder is fixedly connected with semi-circular crushing teeth. The inner bottom wall of the crushing cylinder is provided with a first screening hole. The output end of the motor is fixedly connected with a rotating shaft. This granular asphalt screening device achieves the effects of crushing and secondary screening of asphalt particles by setting a crushing cylinder, a motor, semi-circular crushing teeth, a first screening hole, a rotating shaft, a rotating plate, crushing teeth, a filter plate, a second screening hole and a vibration motor. It has the advantages of fast screening speed, uniform specifications of the screened asphalt particles, and high utilization rate of asphalt particles, and solves the problems of slow screening speed of the existing asphalt screening device, different sizes of the screened asphalt particles, and the inability to reuse the large-sized asphalt particles, resulting in waste of materials.

[0004] In view of the above related technologies, in the prior art, workers use a vibration motor to act on the housing, so that the internal filter plate and the diversion plate are vibrated, so that the asphalt raw materials are more easily screened and transported. However, the diameter of the second discharge pipe is smaller than the entire thickness of the housing. When the amount of asphalt raw materials falling on the diversion plate per unit time is greater than the discharge amount of the second discharge pipe, the asphalt raw materials are likely to accumulate on the diversion plate. Although both the diversion plate and the housing are vibrated by the vibration, it can only affect the asphalt raw materials in the area near the diversion plate and the housing, and the influence on the middle area of the asphalt raw materials is small. There is a possibility that the asphalt raw materials are blocked inside the housing, reducing the discharge effect of the screening device. Summary of the Utility Model

[0005] In order to improve the discharge effect of the cold bin, this application provides a cold bin with an anti-blocking structure.

[0006] The cold bin with an anti-blocking structure provided by this application adopts the following technical solutions:

[0007] A cold material bin with an anti-blocking structure, comprising a bin body, an inlet and an outlet are arranged on the bin body, the diameter of the outlet is smaller than that of the inlet, a rotating frame is rotatably connected to the bin body, a screening net is installed on the rotating frame, the screening net covers the inlet of the bin body, a rotating member for driving the rotating frame to rotate is arranged on the bin body, and an anti-blocking component for conveying asphalt raw materials is arranged on the bin body.

[0008] By adopting the above technical solution, when screening asphalt raw materials, the staff uses the rotating member to drive the rotating frame to adjust the angle of the screening net, so that the asphalt raw materials move and are screened. The screened asphalt raw materials fall into the bin body. At the same time, the anti-blocking component is used to convey the asphalt raw materials in the bin body, so that the asphalt raw materials can be smoothly discharged from the outlet of the bin body, achieving the effect of screening asphalt raw materials. The staff uses the anti-blocking component to convey the asphalt raw materials accumulated inside the bin body, so that the outer and middle parts of the asphalt raw materials are both stressed and move, and are smoothly discharged from the outlet of the bin body, reducing the possibility of asphalt raw materials accumulating inside the bin body and improving the discharging effect of the cold material bin.

[0009] Optionally, the anti-blocking component includes a first vibration motor and a vibration plate. The vibration plate is connected at a position inside the bin body close to the outlet. The first vibration motor is arranged on one side outside the bin body. A first transmission shaft is installed on the first vibration motor. A first installation pipe is connected to the bin body. The first transmission shaft passes through the first installation pipe and is connected to the vibration plate.

[0010] By adopting the above technical solution, when conveying asphalt raw materials, the staff starts the first vibration motor, so that the first transmission shaft transmits the vibration force to the vibration plate, thereby driving the vibration plate and the side wall of the bin body to vibrate together, so that the middle and outer regions of the asphalt raw materials are simultaneously subjected to the vibration force and move, and the asphalt raw materials are smoothly discharged from the outlet of the bin body, achieving the effect of conveying asphalt raw materials.

[0011] Optionally, the anti-blocking component includes a second vibration motor, a vibration frame and a connecting spring. The vibration frame is arranged at a position inside the bin body close to the outlet. A sliding rod is connected to the inner wall of the bin body.

The second vibration motor is arranged outside the bin body. A second installation pipe is installed on the bin body. A second transmission shaft is installed on the second vibration motor. The second transmission shaft passes through the second installation pipe and is connected to the vibration frame.

[0012] By adopting the above technical solution, when driving the asphalt raw material, the staff starts the second vibration motor, and transmits the vibration force to the vibration frame through the second transmission shaft. At the same time, the vibration frame is limited by the sliding rod and pressed by the connecting spring, so that the vibration frame vibrates and moves a short distance, thereby transmitting the vibration force to the asphalt raw material within the moving range of the vibration frame. The asphalt raw material moves under the force and is discharged from the discharge port of the bin body, achieving the effect of driving the asphalt raw material.

[0013] Optionally, a plurality of extension plates are connected to the vibration frame.

[0014] By adopting the above technical solution, the extension plates are used to further expand the action range of the vibration frame, so that more asphalt raw materials are forced to move per unit time, further reducing the possibility of the asphalt raw material blocking the bin body.

[0015] Optionally, the anti-blocking assembly includes a rotating motor, a driving shaft, a driven shaft and a stirring frame. The driving shaft and the driven shaft are both rotatably connected to the bin body, and the axes of the driving shaft and the driven shaft coincide. The rotating motor is installed on the outer side wall of the bin body and is coaxially connected to the driving shaft. The stirring frame is detachably connected between the driving shaft and the driven shaft.

[0016] By adopting the above technical solution, when driving the asphalt raw material, the staff starts the rotating motor to rotate the driving shaft, drives the stirring frame to rotate, and the driven shaft assists in rotating. The stirring frame stirs the asphalt raw material within its range, so that the asphalt raw material is discharged from the discharge port of the bin body, achieving the effect of driving the asphalt raw material.

[0017] Optionally, retaining sleeves are detachably connected to both the driving shaft and the driven shaft. The stirring frame is a portal frame. Both ends of the stirring frame are connected with rotating disks, and limiting keys are connected to the rotating disks. Limiting grooves are formed on both the driving shaft and the driven shaft. The stirring frame is sleeved between the driving shaft and the driven shaft through the rotating disks. The limiting keys are located in the limiting grooves, and the stirring frame abuts between the two retaining sleeves.

[0018] By adopting the above technical solution, during installation, the staff sleeved a retaining sleeve on both the driving shaft and the driven shaft, sleeved the stirring frame between the driving shaft and the driven shaft, inserted the limiting key into the limiting groove, and then restricted the retaining sleeve to restrict the position of the stirring frame, realizing the installation of the stirring frame.

[0019] Optionally, a locking bolt is inserted through the retaining sleeve, and a locking nut is in threaded cooperation with the locking bolt.

[0020] By adopting the above technical solution, when installing the retaining sleeve, the worker passes the locking bolt through the retaining sleeve and the driving shaft, and rotates the locking nut to make the locking nut press against the retaining sleeve. Similarly, the installation of the retaining sleeve and the driven shaft is realized, and the detachable installation of the retaining sleeve is achieved.

[0021] Optionally, a plurality of stirring rods are connected to the stirring frame.

[0022] By adopting the above technical solution, the stirring rods are used to increase the action range of the stirring frame, so that more asphalt raw materials are stirred per unit time.

At the same time, the anti-blocking component is used to drive the asphalt raw materials in the bin body, so that the asphalt raw materials are smoothly discharged from the discharge port of the bin body, and the effect of screening asphalt raw materials is achieved. The worker uses the anti-blocking component to drive the asphalt raw materials accumulated inside the bin body, so that the external and middle parts of the asphalt raw materials are stressed and move, and are smoothly discharged from the discharge port of the bin body, reducing the possibility of asphalt raw materials accumulating inside the bin body and improving the discharging effect of the cold material bin;

[0025] 2.

Detailed implementation manners

[0034] The following further elaborates on the present application Figures 1-6 with reference to the accompanying drawings.

[0035] Embodiment 1 of the present application discloses a cold material silo with an anti-blocking structure. Referring to Figure 1 and Figure 2 , the cold material silo with an anti-blocking structure includes a silo body 1 and a fixing frame 11. A plurality of silo bodies 1 are installed on the fixing frame 11. In this embodiment, two are taken as an example. The silo body 1 is arranged in a frustum shape, and the larger end of the silo body 1 is the feeding port 12, and the smaller end is the discharging port 13. A rotating frame 2 is hinged on the silo body 1, and a screening mesh 21 is installed on the rotating frame 2. The screening mesh 21 covers the feeding ports 12 of the two silo bodies 1. A rotating member 3 is arranged on the fixing frame 11. The rotating member 3 is a driving cylinder, and the rotating member 3 is hinged between the fixing frame 11 and the rotating frame 2.

[0036] Referring to Figure 2 and Figure 3 , an anti-blocking component 4 is arranged on the silo body 1. The anti-blocking component 4 includes a first vibration motor 41 and a vibrating plate 42. The vibrating plate 42 is welded to the inner wall of the silo body 1 at a position close to the discharging port 13, and the vibrating plate 42 is located at the middle position of the silo body 1. A first installation pipe penetrates through the silo body 1. The first vibration motor 41 is arranged on one side of the silo body 1. A first transmission shaft 411 is installed on the first vibration motor 41. The first transmission shaft 411 passes through the first installation pipe and is welded to the vibrating plate 42.

[0037] The staff uses the first transmission shaft 411 to transmit the vibration force generated by the first vibration motor 41 to the vibrating plate 42, causing the vibrating plate 42 and the bin body 1 to vibrate together, so that the inside and outside of the asphalt raw material are stressed simultaneously and move, enabling the asphalt raw material to be smoothly discharged from the bin body 1.

[0038] The implementation principle of the cold bin with an anti-blocking structure in Embodiment 1 of this application is as follows: When screening asphalt raw materials, the staff pours the asphalt raw materials onto the screening net 21, and at the same time starts the rotating member 3 to make the rotating frame 2 rotate, so as to adjust the angle of the screening net 21, enabling the asphalt raw materials to fall into the bin body 1. Subsequently, the first vibration motor 41 is started, and the vibration force is transmitted to the vibrating plate 42 through the first transmission shaft 411, causing the asphalt raw materials in the bin body 1 to move under vibration, and enabling the asphalt raw materials to be smoothly discharged from the bin body 1, achieving the effect of screening asphalt raw materials.

[0039] The staff uses the anti-blocking component 4 to drive the asphalt raw materials piled up inside the bin body 1, so that the external and middle parts of the asphalt raw materials are stressed and move, and are smoothly discharged from the discharge port 13 of the bin body 1, reducing the possibility of asphalt raw materials piling up inside the bin body 1 and improving the discharging effect of the cold bin.

The vibrating frame 44 is arranged inside the bin body 1. A connecting plate is fixedly connected to the inner wall of the bin body 1, and a sliding rod is fixedly connected to the connecting plate. The sliding rod is horizontally arranged. The vibrating frame 44 is slidably fitted on the sliding rod, and two connecting springs 45 are sleeved on the sliding rod. The vibrating frame 44 is located between the two connecting springs 45.

[0042] Refer to Figure 4 , a second installation pipe penetrates through the bin body 1. The second vibration motor 43 is arranged outside the bin body 1. A second transmission shaft 431 is installed on the second vibration motor 43. The second transmission shaft 431 passes through the second installation pipe and is welded to the vibrating frame 44.

[0043] Refer to Figure 4 , in order to increase the acting range of the vibrating frame 44, a number of extension plates 441 are welded on the vibrating frame 44.

[0044] When driving the asphalt raw materials, the staff starts the second vibration motor 43, and transmits the vibration force to the vibrating frame 44 through the second transmission shaft 431. At the same time, the vibrating frame 44 is limited by the sliding rod and pressed by the connecting spring 45, causing the vibrating frame 44 to move a small distance while vibrating slightly, so as to transmit the vibration force to the asphalt raw materials within the moving range of the vibrating frame 44. The asphalt raw materials are stressed and move, and are discharged from the discharge port 13 of the bin body 1, achieving the effect of driving the asphalt raw materials.

[0045] Embodiment 3: The difference between this embodiment and Embodiment 1 lies in the different structure of the anti-blocking component 4.

[0046] Referring to Figure 5 and Figure 6 , the anti-blocking component 4 includes a rotating motor 46, a driving shaft 47, a driven shaft 48 and a stirring frame 49. The driving shaft 47 and the driven shaft 48 are both rotatably connected to the bin body 1, and the driving shaft 47 and the driven shaft 48 are on the same straight line. The rotating motor 46 is installed on the outer side wall of the bin body 1 and is coaxially connected to the driving shaft 47.

[0047] Referring to Figure 5 and Figure 6 , a retaining sleeve 5 is sleeved on the driving shaft 47. A locking bolt 51 is passed through between the retaining sleeve 5 and the driving shaft 47. A locking nut 52 is in threaded fit with the locking bolt 51, and the locking nut 52 abuts against the retaining sleeve 5. Similarly, a retaining sleeve 5 is provided on the driven shaft 48. The stirring frame 49 is a portal frame. Both ends of the stirring frame 49 are fixedly connected with rotating discs 491. A sleeve hole is formed in the rotating disc 491, and a limiting key 492 is fixedly connected to the rotating disc 491. Limiting grooves are formed at positions corresponding to the limiting key 492 on the driving shaft 47 and the driven shaft 48. The stirring frame 49 is sleeved between the driving shaft 47 and the driven shaft 48 through the rotating discs 491. The limiting key 492 is embedded in the limiting groove, and the rotating disc 491 abuts between the two retaining sleeves 5.

[0048] Referring to Figure 6 , in order to increase the stirring range of the stirring frame 49, a plurality of stirring rods 493 are welded on the stirring frame 49.

[0049] When transferring the asphalt raw material, the staff starts the rotating motor 46 to rotate the driving shaft 47, drive the stirring frame 49 to rotate, and the driven shaft 48 rotates assistingly. The stirring frame 49 and the stirring rods 493 stir the asphalt raw material, so that the asphalt raw material is discharged from the discharge port 13 of the bin body 1, achieving the effect of transferring the asphalt raw material.
