For example, for the large-scale storage of granular materials such as grain or ore, when the granular materials need to be taken out of the material pool, it is completed by a material taking machine. In the prior art, a bridge-type excavator is a relatively common material taking device.

[0003] Generally, a large material taking arm is arranged on one side of the material taking machine. However, setting the material taking arm on one side will result in a material taking dead angle, and the materials in the material pool cannot be completely taken out.

However, the applicant found that when the bridge-type double-arm material taking machine is used, only one arm can be used at a time. When one material taking arm takes materials at the dead angle, the other material taking arm cannot take materials. Therefore, the comprehensive material taking efficiency of the two material taking arms cannot meet the higher speed requirements. Content of the Utility Model

[0028] Figures 1 - 6 This is the best embodiment of the present utility model. The following further describes the present utility model in conjunction with the attached Figures 1 - 6 drawings.

[0029] As Figures 1 - 2 shown, a bridge-type bidirectional material taking machine of the present utility model includes a first material taking mechanism 5 and a second material taking mechanism 6 which are independently arranged. The first material taking mechanism 5 and the second material taking mechanism 6 are respectively installed above the material pool 1, and both the first material taking mechanism 5 and the second material taking mechanism 6 can move along the length direction of the material pool 1, and the two material taking mechanisms can take materials independently.

[0030] Among them, both the first material taking mechanism 5 and the second material taking mechanism 6 include a support frame 8, a traveling frame 13 and a material taking boom 10. The support frame 8 is erected above the material pool 1, and the support frame 8 can move along the length direction of the material pool 1. The traveling frame 13 is movably arranged on the support frame 8, and the moving direction of the traveling frame 13 is perpendicular to the moving direction of the support frame 8. The material taking boom 10 is arranged on the traveling frame 13, and the swinging direction of the material taking boom 10 is parallel to the traveling direction of the traveling frame 13. The material taking boom 10 extends from the traveling frame 13 into the material pool 1. The material taking boom 10 is inclined, and the end of the material taking boom 10 can take materials at the corner dead ends of the material pool 1. The material taking booms 10 of the first material taking mechanism 5 and the second material taking mechanism 6 are arranged in opposite directions, that is, the material taking booms 10 of the first material taking mechanism 5 and the second material taking mechanism 6 are respectively arranged on both sides of the traveling direction of the traveling frame 13. Such a setting can enable the first material taking mechanism 5 and the second material taking mechanism 6 to take materials at the dead ends on both sides of the material pool 1 respectively. And when the first material taking mechanism 5 takes materials on one side of the material pool 1, the second material taking mechanism 6 can take materials on the other side of the material pool 1 at other positions in the material pool 1. The two material taking mechanisms can take materials at the dead ends on both sides at the same time, improving the material taking efficiency. Feeding belts 3 and discharging belts 2 are respectively arranged on both sides of the material pool 1. A feeding belt is arranged between the material taking boom 10 and the discharging belt 2. The materials taken out of the material pool 1 by the material taking boom 10 are conveyed to the discharging belt 2 through the feeding belt.

[0031] As Figures 3 - 5 shown, a feeding belt 3 and a discharging belt 2 are respectively arranged on both sides of the material pool 1. Material pool guide rails 7 are arranged along the length direction of the material pool 1 on both sides of the material pool 1. Wheel seats are arranged on the bottom side of the support frame 8, and wheels are arranged in the wheel seats. The support frame 8 is arranged on the material pool guide rails 7 by rolling of the wheels. The support frame 8 rolls along the material pool guide rails 7 to change the material taking position. A material taking guide rail 9 is arranged on the support frame 8, and the material taking guide rail 9 is arranged perpendicular to the length direction of the material pool 1. Wheel seats are also arranged on the bottom side of the traveling frame 13, and wheels are arranged in the wheel seats. The traveling frame 13 is arranged on the material taking guide rail 9 by rolling of the wheels. Therefore, the material taking boom 10 can also be movably installed on the material taking guide rail 9. The movement of the material taking boom 10 can take all the materials at the position of the material pool 1.

[0032] The material fetching boom 10 continuously transports the materials in the material pool 1 to the walking frame 13. The feeding belt includes a transfer conveyor belt 11 and a material transporting conveyor belt 12. The transfer conveyor belt 11 is arranged below the end of the material fetching boom 10 close to the walking frame 13. After the materials are transported up by the material fetching boom 10, they fall on the transfer conveyor belt 11. At the end of the transfer conveyor belt 11, there is a butt-jointed material transporting conveyor belt 12. The material transporting conveyor belt 12 is installed on the support frame 8. The materials on the transfer conveyor belt 11 then fall from the end onto the material transporting conveyor belt 12. The material transporting conveyor belt 12 is arranged along the length direction perpendicular to the material pool 1. The conveying end of the material transporting conveyor belt 12 extends to the side of the material pool 1 and is butt-jointed with the discharging belt 2 at the edge of the material pool 1. Therefore, the materials on the material transporting conveyor belt 12 are further transported along the material transporting conveyor belt 12 to the discharging belt 2 and finally transported out from the discharging belt 2.

[0033] In this embodiment, the material fetching booms 10 on the two material fetching mechanisms respectively and simultaneously fetch materials from the dead corners on both sides of the material pool 1. The lengths of the material fetching booms 10 are the same. One end of the material fetching boom 10 close to the walking frame 13 is connected with a material fetching driving mechanism 14 that drives it to complete the material fetching action. A number of material fetching buckets 17 are arranged at intervals on the material fetching boom 10. The material fetching driving mechanism 14 drives each material fetching bucket 17 to continuously dig and transport the materials up. The material fetching boom 10 is also connected with a swing driving mechanism that drives it to swing. The swing driving mechanism can change the inclination degree of the material fetching mechanism as the depth of the materials changes. And in this embodiment, the material pool 1 is divided into several small material troughs along the length direction. The swing driving mechanism can also be used to lift the material fetching boom 10 and move it to the next material trough to fetch materials. In this embodiment, the swing driving mechanism can adopt a winch.

[0034] Above the material pool 1, there is also a distributing machine 4. The distributing machine 4 is arranged between the first material fetching mechanism 5 and the second material fetching mechanism 6. On both sides of the material pool 1, there are respectively arranged distributing moving guide rails 15. The distributing moving guide rails 15 are arranged inside the material pool guide rails 7, and the distributing moving guide rails 15 do not affect the movement of the material fetching mechanism. At the bottom side of the distributing machine 4, there is a wheel seat, and wheels are arranged inside the wheel seat. The distributing machine 4 is arranged on the distributing moving guide rails 15 by rolling of the wheels. The materials are transported from the feeding belt 3. At one end of the distributing machine 4 close to the feeding belt 3, there is a baffle plate 16. Through the baffle plate 16, the materials on the feeding belt 3 are transferred to the distributing machine 4. The distributing machine 4 then evenly drops the materials into the material pool 1. When fetching materials, the first material fetching mechanism 5 and the second material fetching mechanism 6 then fetch materials from the material pool 1.

[0035] As Figure 6As shown in the figure, a number of material buckets 17 are provided on the material fetching jib 10. Material is dug through the material buckets 17. A number of material fetching teeth are fixedly arranged at the material fetching end of the material buckets 17. The material fetching teeth include side material fetching teeth 18 and bottom material fetching teeth 19. The side material fetching teeth 18 are respectively installed on both sides of the material bucket 17, and the side material fetching teeth 18 on both sides are flared outward. The bottom material fetching teeth 19 are installed at the bottom of the material fetching end of the material bucket 17, and the end of the bottom material fetching teeth 19 is inclined towards the bottom side. The material fetching opening of the material bucket 17 is flared, which can make the material bucket 17 fetch materials better.

[0036] In this embodiment, the material fetching teeth are all in a triangular pyramid shape. The end of the material fetching tooth is the tip of the triangular pyramid. The surface of the material fetching tooth facing the inside of the bucket is a plane. The triangular pyramid-shaped material fetching teeth are not easy to break. In this embodiment, the tip of the material fetching tooth and the edges of the triangular pyramid are both smoothed. The material fetching teeth are all made of plastic material, which can avoid excessive friction damage to materials such as grains when fetching materials.

[0037] When the present utility model is in use, the first material fetching mechanism 5 moves along the cloth feeding moving guide rail 15 to the position where materials in the material pool 1 need to be fetched. The swing driving mechanism swings the material fetching jib 10 to the position of the materials in the material pool 1. The material fetching driving mechanism 14 drives the material fetching jib 10 to fetch materials. As the height of the materials decreases, the swing driving mechanism makes the material fetching jib 10 swing to maintain stable material fetching, and the walking frame 13 moves along the material fetching guide rail 9 to ensure that the material fetching jib 10 fetches all the materials on one side of the material pool 1; at the same time, the second material fetching mechanism 6 also moves to the position where materials in the material pool 1 need to be fetched to start fetching materials, and its walking frame 13 moves along the material fetching guide rail 9 to ensure that the material fetching jib 10 fetches all the materials on the other side of the material pool 1. The two material fetching mechanisms fetch materials simultaneously. After the first material fetching mechanism 5 finishes fetching the materials on one side of its fetching position and moves to the next place, at this time, the second material fetching mechanism 6 moves to this place to fetch the materials on the other side of the material pool 1. The present utility model can ensure that all the materials in the dead corners of the material pool 1 can be fetched while improving the overall material fetching efficiency.

[0038] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
