Description

Technical Field

[0001] The present invention relates to the technical field of storage equipment, and particularly to a transportation storage bin for road paving. Background Art

[0002] A transportation storage bin for road paving is a device specifically used for storing and transporting road construction materials (such as sand and ash). After being transported to a designated location, the materials are discharged, or the transport vehicle discharges the materials while moving, aiming to improve construction efficiency, ensure material quality, and reduce waste.

[0003] In some storage containers for particles or powders, when the materials pass through the discharge port, the discharge port is at the bottom of the storage bin and its diameter is much smaller than that of the storage bin. During discharging, the extrusion pressure between the materials becomes larger, causing the discharge port to be easily blocked. Therefore, the prior art often adopts some active discharging mechanisms to ensure the continuous discharge of materials, thereby also avoiding the occurrence of blockage problems. For example, a spiral discharging mechanism.

[0004] However, the existing discharging mechanism requires the continuous operation of a motor, that is, continuous power supply. The driving part is restricted by power supply, consuming a large amount of electric energy and increasing the operating cost of the equipment. The requirements for the motor, circuit connection, and stability also make the structure relatively complex, requiring more energy and cost for maintenance and repair. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, a transportation storage bin for road paving according to the present invention drives the vertical rods and stirring rods in two discharging pipes to stir the materials above the discharging pipes through a swing rod that can be impacted by the materials and swing in a vertical plane. Moreover, the swing rod can continuously swing irregularly under the action of an elastic member, thereby continuously avoiding blockage of the discharge port. Compared with the prior art, the present invention has a simple structure, is easy to maintain, can continuously discharge materials automatically without adding a power driving device, and saves costs.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a transport and storage bin for road paving, comprising a bin, a base plate, a swing arm and a pair of discharge pipes, the base plate is arranged at the bottom of the bin, the pair of discharge pipes are arranged through the base plate, a pair of fixed plates are arranged vertically and parallelly between the pair of discharge pipes, a rotating shaft is rotatably arranged between the pair of fixed plates, guide openings are opened at positions where the discharge pipes face each other and at heights corresponding to the rotating shaft, the center position of the swing arm is fixedly connected to the rotating shaft and both ends respectively pass through the guide openings to the discharge pipes on both sides, an elastic member is arranged between the swing arm and the upper and lower walls of the guide opening, vertical upright poles are respectively arranged on the swing arm and corresponding to the axial center lines of the two discharge pipes, the upper ends of the upright poles extend to the horizontal position of the base plate and a stirring rod is fixedly arranged on the upper ends of the upright poles, valves are arranged at the bottoms of the pair of discharge pipes, and an auxiliary dredging mechanism is arranged at the center position of the base plate, which can stir the material on the base plate.

[0007] Preferably, the auxiliary dredging mechanism includes a nut, a screw rod and a plurality of movable plates. The nut is arranged at the center position of the base plate, the screw rod is screwed into the nut, a limit plate is rotatably arranged at the lower end of the screw rod, and a plurality of movable plates are evenly arranged at the upper end of the screw rod. Both sides of the limit plate are vertically slidably connected to the outer side walls of a pair of discharge pipes through limit members, and a driving member is arranged at the bottom of the limit plate.

[0008] Preferably, the limiting member includes a slide rail and a slider, the slide rail is vertically arranged on the outer side wall of the feeding tube, the slider is arranged at both ends of the limiting plate, and the slider is slidably connected to the slide rail.

[0009] Preferably, the movable plate is arc-shaped, and a plurality of movable plates are arranged with the screw rod as the center to form a "windmill" shape.

[0010] Preferably, a pair of feeding tubes have inner walls with grooves at heights corresponding to the horizontal position of the swing arm, proximity sensors are arranged in the grooves, and an alarm is arranged outside the feeding tubes.

[0011] Preferably, force-bearing plates are provided at both ends of the swing rod, and the force-bearing plates are arc-shaped plates and their shapes match the inner walls of the discharge pipe.

[0012] Preferably, barrier curtains are provided on both inner and outer sides of the guide opening.

[0013] Preferably, the elastic member is a spring capable of stretching and compressing.

[0014] Preferably, the driving member is a push plate.

[0015] The present invention provides a transport storage bin for road paving, which has the following beneficial effects:

[0016] 1. In the present invention, a swing rod capable of being impacted by materials and swinging in a vertical plane drives the vertical rods and stirring rods in two blanking pipes to stir the materials above the blanking pipes. Moreover, under the action of an elastic member, the swing rod can continuously swing irregularly, thereby continuously avoiding blockage of the discharge port. Compared with the prior art, the structure of the present invention is simple, easy to maintain, can continuously discharge materials automatically without adding a power driving device, and saves costs;

[0017] 2. The present invention is provided with an auxiliary dredging mechanism. When discharging materials at the discharge port, at the beginning, the materials are in a static state, and blockage may occur (with a low probability) after the valve is opened. The driving member can be used to drive the limiting plate and the lead screw to move vertically. Since the lead screw is threadedly connected to the nut at the bottom of the silo, when the lead screw moves up and down, it can also rotate, thereby driving the movable plate to move vertically while rotating, and further achieving the purpose of stirring the materials near the corresponding blanking pipe in the silo to assist in discharging materials;

[0018] 3. In the present invention, a proximity sensor is provided at the position where the swing rod is horizontal corresponding to the blanking pipe. Once the end of the swing rod remains stationary for a long time, that is, there is no material in the blanking pipe to impact the swing rod, it indicates that both blanking pipes are blocked. If the proximity sensor is continuously sensed or not sensed for a long time, the alarm will be triggered to give an alarm to remind the personnel that it is necessary to dredge through the auxiliary dredging mechanism. The design is relatively reasonable, eliminating the problem of blockage caused by special circumstances affecting material discharge. BRIEF DESCRIPTION OF THE DRAWINGS

The center position of the swing arm 3 is fixedly connected to the rotating shaft 5, and the two ends of the swing arm 3 respectively pass through the guide port 6 to the feeding tubes 8 on both sides. An elastic member 4 is provided between the swing rod 3 and the upper and lower walls of the guide port 6. Vertical upright poles 10 are respectively provided on the swing rod 3 and on the axis lines of the two discharge pipes 8. The upper ends of the upright poles 10 extend to the horizontal position of the bottom plate 16 and a stirring rod 17 is fixedly provided on the upper ends of the upright poles 10. A valve 7 is provided at the bottom of a pair of discharge pipes 8. An auxiliary dredging mechanism is provided at the center of the bottom plate 16 to stir the material on the bottom plate 16. The auxiliary dredging mechanism includes a nut 15, a screw rod 14 and a plurality of movable plates 13. The nut 15 is provided at the bottom of the bottom plate 16. The screw rod 14 is screwed into the screw nut 15 at the center position, the screw rod 14 is rotatably provided with a limit plate 12 at the lower end of the screw rod 14, and a plurality of movable plates 13 are evenly arranged at the upper end of the screw rod 14. The two sides of the limit plate 12 are vertically slidably connected with the outer side walls of a pair of feeding tubes 8 through limit members, and a driving member 23 is arranged at the bottom of the limit plate 12; the limit member includes a slide rail 18 and a slider 19, the slide rail 18 is vertically arranged on the outer side wall of the feeding tube 8, the slider 19 is arranged at both ends of the limit plate 12, and the slider 19 is slidably connected with the slide rail 18; the movable plate 1 3 is arc-shaped, and multiple movable plates 13 are arranged with the screw rod 14 as the center to form a "windmill" shape; a pair of grooves 9 are opened on the inner wall of the feeding tube 8 at the height position corresponding to the horizontal position of the swing rod 3, and a proximity sensor 1 is arranged in the groove 9, and an alarm 20 is arranged on the outside of the feeding tube 8; force plates 2 are arranged at both ends of the swing rod 3, and the force plates 2 are arc-shaped plates and their shape matches the inner wall of the feeding tube 8; blocking curtains 21 are respectively arranged on the inner and outer sides of the guide port 6; the elastic member 4 adopts a spring that can be stretched and compressed; the driving member 23 is a push plate.

[0026] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0027] According to the appended drawings of the specification Figures 1-4 As can be seen, when the present invention is in use, since the materials in the bin 11 accumulate under gravity on the bottom plate 16 and the discharge pipe 8 connected to the bottom plate 16, the valve 7 on the discharge pipe 8 is opened. Here, a slide gate valve can be used. The materials will be discharged along a pair of discharge pipes 8. During the discharging process, the materials will impact the stirring rod 17, the vertical rod 10, and the swing rod 3. Among the two discharge pipes 8, the stirring rod 17, the vertical rod 10, and the swing rod 3 will be impacted by the materials. Under normal circumstances, the impacts on both sides are irregular (the discharging speed and flow rate of the materials are both irregular). And since the rotating shaft 5 at the center of the swing rod 3 is rotatably connected to the side wall of the fixing plate 22 between a pair of discharge pipes 8, the irregular impacts will inevitably cause the swing rod 3 and the vertical rod 10 to swing irregularly around the rotating shaft 5. Additionally, an elastic member 4 is provided between the swing rod 3 and the guide port 6. During the swinging process, under the action of the elastic member 4, the swinging of the swing rod 3 and the vertical rod 10 is not easy to stop, with stronger persistence and always in a dynamic state. During the swinging process, the stirring rod 17 at the top of the vertical rod 10 can stir the materials at the upper end position of the discharge pipe 8 to prevent them from being squeezed together and causing blockage. Compared with the prior art, the present invention drives the vertical rod 10 and the stirring rod 17 in the two discharge pipes 8 to stir the materials above the discharge pipes 8 through a swing rod 3 that can be impacted by the materials and swing in a vertical plane. And the swing rod 3 can continuously swing irregularly under the action of the elastic member 4, so as to continuously avoid blockage of the discharge port. The structure of the present invention is simple, easy to maintain, can continuously and automatically discharge materials without adding a power driving device, saves energy, and saves costs.

[0028] When the present invention starts to work, it should be noted that: when the valve 7 is first opened for discharging, since the stirring rod 17, the vertical rod 10, and the swing rod 3 are in a static state, if the materials are blocked at the beginning, the auxiliary dredging mechanism provided at the center position of the bottom plate 16 needs to do some dredging work. As long as there is material discharged, it will make the swing rod 3, the vertical rod 10, and the stirring rod 17 work, achieving continuous dynamic dredging and thus avoiding the situation of blockage. The above problems are also small-probability events, and solutions are given.

[0029] Among them, the auxiliary dredging mechanism includes a nut 15, a screw rod 14, and a plurality of movable plates 13. The nut 15 is arranged at the center position of the bottom plate 16. The screw rod 14 is screwed into the nut 15. A limit plate 12 is rotatably arranged at the lower end of the screw rod 14. A plurality of movable plates 13 are evenly arranged at the upper end of the screw rod 14. Both sides of the limit plate 12 are vertically slidably connected to the outer side walls of a pair of discharge pipes 8 through limit members. A driving member 23 is arranged at the bottom of the limit plate 12.

[0030] The driving member 23 here can be a push plate. During use, the operator pushes the push plate upward to drive the limiting plate 12 and the lead screw 14 to move upward. Since the lead screw 14 is threadedly connected to the nut 15 at the bottom of the bin 11, when the lead screw 14 moves up and down, it can also rotate. Thus, while driving the movable plate 13 to move vertically, it can also rotate, so as to stir the materials near the corresponding discharge pipe 8 in the bin 11, achieving the purpose of assisting in discharging. Of course, the auxiliary dredging mechanism is only used in special cases. Therefore, the driving member 23 can also be a linear motor, and the linear motor is used to drive the limiting plate 12 to move up and down. The temporary use will not conflict with the energy saving of the present invention. It should be noted that the use of the driving member 23 should not affect the swing of the swing rod 3.

[0031] Among them, the limiting member includes a slide rail 18 and a slider 19. The slide rail 18 is vertically arranged on the outer side wall of the discharge pipe 8, and the slider 19 is arranged at both ends of the limiting plate 12. The slider 19 is slidably connected to the slide rail 18. The sliding fit structure of the slider 19 and the slide rail 18 is simple, which is convenient for maintenance and repair.

[0032] Particularly, the movable plate 13 is arc-shaped, and a plurality of movable plates 13 are arranged around the lead screw 14 to form a "windmill" shape. As Figure 4 shown, rotating clockwise can push the materials inward, and rotating counterclockwise can push the materials outward. No matter which direction, the purpose is to stir the materials near the upper part of the discharge pipe 8 to avoid blockage.

[0033] Among them, a pair of grooves 9 are opened on the inner walls of the two discharge pipes 8 at the height position corresponding to when the swing rod 3 is horizontal. A proximity sensor 1 is arranged in the groove 9, and an alarm 20 is arranged outside the discharge pipe 8.

[0034] During operation, once a special situation occurs, such as the materials above the two discharge pipes 8 are just blocked at the same time (the probability is very low. As long as the two discharge pipes 8 are not blocked at the same time, the swing rod 3 will keep swinging), then the swing rod 3 will remain stationary continuously, indicating that the two discharge pipes 8 are blocked at the same time. If the proximity sensor 1 is continuously sensed or continuously not sensed, the alarm 20 will be triggered to give an alarm, reminding the operator that auxiliary dredging is needed, and the auxiliary dredging mechanism can be used for dredging. The design is relatively reasonable, eliminating the problem that the blockage in the small probability situation affects the discharging.

[0035] Among them, force-bearing plates 2 are arranged at both ends of the swing rod 3. The force-bearing plates 2 are arc-shaped plates and their shapes match the inner wall of the discharge pipe 8. The arc-shaped design is to ensure that it can still swing normally while being close to the inner wall of the discharge pipe 8. At the same time, the force-bearing plates 2 increase the area of being impacted by the materials to a certain extent, and they have a certain weight themselves, which can better make the swing rod 3 swing, thus avoiding the blockage of the discharge pipe 8.

[0036] Wherein, blocking curtains 21 are respectively arranged on the inner and outer sides of the guiding port 6 to prevent the material from flying out and prevent external impurities from entering the feeding pipe 8.

[0037] The elastic member 4 between the swing rod 3 and the side wall of the guiding port 6 adopts a spring that can be stretched and compressed. The spring has a simple structure, low cost, and obvious effect.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
