Description

Technical Field

[0001] The invention relates to the technical field of storage equipment, in particular to a transport storage bin for road paving. Background Art

[0002] The transport storage silo used for road paving is a kind of equipment specially used for storing and transporting road construction materials (such as sand and ash). After being transported to the 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 granular or powder storage containers, when the material passes through the discharge port, the discharge port is at the bottom of the storage bin and its diameter is much smaller than the diameter of the storage bin. When 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 discharge mechanisms to ensure the continuous discharge of materials, thereby avoiding the occurrence of blockage problems, such as spiral discharge mechanisms.

[0004] However, the existing discharge mechanism requires the continuous operation of the motor, that is, a continuous supply of electricity is required. The driving part is restricted by electricity, consumes a large amount of electricity, and increases the operating cost of the equipment. The requirements of the motor, circuit connection and stability also make the structure relatively complex, requiring more energy and cost for repair and maintenance. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a transport and storage bin for road paving, which drives the vertical rods and stirring rods in the two discharge pipes to stir the materials above the discharge pipes through a swing arm that can swing in a vertical plane when hit by the materials, and the swing arm can continuously swing irregularly under the action of the elastic member, thereby continuously avoiding the blockage of the discharge port. Compared with the prior art, the present invention has a simple structure and is easy to maintain. It can continuously and automatically discharge materials without adding a power drive device, thereby saving 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: 1. The present invention uses a swing rod that can swing in a vertical plane due to the impact of the material to drive the vertical rods and the stirring rods in the two feeding pipes to stir the materials above the feeding pipes, and the swing rod can continuously swing irregularly under the action of the elastic member, so as to continuously avoid the blockage of the discharge port. Compared with the prior art, the present invention has a simple structure and is easy to maintain. It can continuously and automatically discharge materials without adding a power drive device, saving costs; 2. The present invention is provided with an auxiliary dredging mechanism. When the discharge port is discharging, the material is in a static state at the beginning. After the valve is opened, a blockage may occur (with a low probability). The limit plate and the screw rod can be driven by the driving member to move in the vertical direction. Since the screw rod is screwed to the nut at the bottom of the silo, the screw rod can also rotate when moving up and down, thereby driving the movable plate to move vertically and rotate at the same time, thereby achieving the purpose of stirring the material near the corresponding discharge pipe in the silo and assisting the discharge; 3. In the present invention, a proximity sensor is provided at a position of the discharge pipe corresponding to the horizontal position of the swing arm. Once the end of the swing arm is in a stationary state for a long time, that is, there is no material in the discharge pipe to hit the swing arm, it means that both discharge pipes are blocked. If the proximity sensor is continuously sensed or has not been sensed for a long time, the alarm will be triggered to alert personnel that it is necessary to dredge the pipe through an auxiliary dredging mechanism. The design is relatively reasonable and eliminates the problem of blockage caused by special circumstances affecting 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.

[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows: According to the instruction manual Figure 1-4It can be seen that when the present invention is used, the material in the silo 11 is accumulated on the bottom plate 16 and the discharge pipe 8 connected to the bottom plate 16 by gravity, and the valve 7 on the discharge pipe 8 is opened. Here, a plug valve can be used, and the material will be discharged along a pair of discharge pipes 8. During the discharge process, the material will hit the stirring rod 17, the vertical rod 10 and the swing rod 3. The stirring rod 17, the vertical rod 10 and the swing rod 3 in the two discharge pipes 8 will be hit by the material. Under normal circumstances, the impact on both sides is irregular (the speed and flow rate of material discharge are irregular), and because the center of the swing rod 3 is The rotating shaft 5 is connected to the side wall of the fixed plate 22 between the pair of discharge pipes 8 by rotation, so irregular impact will inevitably cause the swing rod 3 and the vertical rod 10 to swing irregularly with the rotating shaft 5 as the center. In addition, an elastic member 4 is arranged 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, and the continuity is stronger, and it is always in a dynamic state. During the swinging process, the stirring rod 17 on the top of the vertical rod 10 can stir the material at the upper end of the discharge pipe 8 to avoid squeezing together and causing blockage. Compared with the prior art, the present invention uses a swing rod 3 that can swing in a vertical plane under the impact of the material to drive the vertical rod 10 and the stirring rod 17 in the two discharge pipes 8 to stir the material above the discharge pipe 8, and the swing rod 3 can continue to swing irregularly under the action of the elastic member 4, so as to continuously avoid the blockage of the discharge port. The present invention has a simple structure and is easy to maintain. It can continuously and automatically discharge materials without adding a power drive device, saving energy and cost.

[0021] When the present invention starts working, it should be noted that: when the valve 7 is first opened for discharge, since the stirring rod 17, the vertical rod 10 and the swing rod 3 are in a static state, if the material is blocked at the beginning, the auxiliary dredging mechanism set at the center of the bottom plate 16 is required to do the dredging work. As long as there is material discharge, the swing rod 3, the vertical rod 10 and the stirring rod 17 will work, and continuous dynamic dredging will be achieved, thereby avoiding blockage. The above problem is also a low-probability event, and a solution is given.

[0022] 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.

[0023] The driving member 23 here can be a push plate. When in use, the personnel push the push plate upward to drive the limit plate 12 and the screw rod 14 to move upward. Since the screw rod 14 is screwed to the nut 15 at the bottom of the silo 11, the screw rod 14 can also rotate when moving up and down, thereby driving the movable plate 13 to move vertically and rotate at the same time, thereby achieving the purpose of stirring the material near the corresponding discharge pipe 8 in the silo 11, and assisting in discharging. Of course, the auxiliary dredging mechanism is only used in special circumstances. Therefore, the driving member 23 can also be a linear motor, which drives the limit plate 12 to move up and down. 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 cannot affect the swing of the rocker arm 3.

[0024] The limiting member includes a slide rail 18 and a slider 19. The slide rail 18 is vertically arranged on the outer wall of the feeding tube 8. The sliders 19 are arranged at both ends of the limiting plate 12. The sliders 19 are slidably connected with the slide rail 18. The sliding matching structure of the slider 19 and the slide rail 18 is simple and easy to repair and maintain.

[0025] Particularly, the movable plate 13 is arc-shaped, and a plurality of movable plates 13 are arranged around the screw rod 14 to form a "windmill" shape, such as Figure 4 As shown, clockwise rotation can push the material inward, and counterclockwise rotation can push the material outward. Regardless of the direction, the purpose is to stir the material near the top of the discharge pipe 8 to avoid blockage.

[0026] A pair of grooves 9 are provided on the inner walls of the feed pipes 8 at heights corresponding to the horizontal positions of the swing rods 3 , a proximity sensor 1 is provided in the grooves 9 , and an alarm 20 is provided on the outside of the feed pipes 8 .

[0027] During operation, once a special situation occurs, such as the materials above the two discharge pipes 8 happen to be 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 arm 3 will continue to swing), then the swing arm 3 will continue to be in a static state, indicating that the two discharge pipes 8 are blocked at the same time, and the proximity sensor 1 is continuously sensed or continuously not sensed, it will trigger the alarm 20 to alarm, reminding personnel that auxiliary dredging is needed, and an auxiliary dredging mechanism can be used for dredging. The design is relatively reasonable, eliminating the problem of blockage in a small probability that affects the discharge of materials.

[0028] Among them, 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. The arc-shaped design is to ensure that it can swing normally when it is close to the inner wall of the feeding tube 8. At the same time, the force plates 2 increase the area impacted by the material to a certain extent, and they have a certain weight, which can better make the swing rod 3 swing, thereby avoiding the blocking of the feeding tube 8.

[0029] Wherein, barrier curtains 21 are respectively arranged on both sides of the inner and outer sides of the guide opening 6 to prevent the material from flying out and to prevent external impurities from entering the discharge pipe 8 .

[0030] The elastic member 4 between the swing rod 3 and the side wall of the guide port 6 is a spring capable of stretching and compressing. The spring has a simple structure, low cost and obvious effect.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
