Description

Technical Field

[0001] The present invention relates to the technical field of material pool reclaiming equipment, and particularly to a bridge-type single-arm reclaiming machine. Background Art

[0002] As is well known, a large amount of storage of granular materials such as grains or ores mostly adopts a material pool, and when it is necessary to discharge the granular materials from the bin, it is completed by a reclaiming machine.

[0003] For example, the Chinese utility model patent CN218667699U discloses a bridge-type double-arm reclaiming machine. It includes a main frame, which is erected above the material pool and reciprocates along the material pool. A traveling vehicle is arranged on the surface of the main frame, and the moving direction of the traveling vehicle is perpendicular to the moving direction of the main frame. A reclaiming boom is arranged on the traveling vehicle, and the feeding end of the reclaiming boom extends from the traveling vehicle into the material pool. At least one reclaiming boom is arranged on each side of the traveling vehicle in the moving direction. It eliminates the reclaiming dead angle in the material pool and improves the reclaiming efficiency.

[0004] However, when using two reclaiming booms with different orientations for reclaiming, although the reclaiming dead angle can be reduced to a certain extent, due to the self-occupation of the reclaiming booms, there are still some reclaiming dead angles in the material pool (please refer to Figure 13 ); the reclaiming boom has a high cost and a complex structure. Using two reclaiming booms not only increases the self-weight of the equipment and the upfront investment cost, but also doubles the subsequent maintenance workload, and there are certain limitations in use. Summary of the Invention

[0046] Specifically, please refer to Figure 2 and Figure 3 It also includes a second conveyor 20 installed on the bridge crane 2. The second conveyor 20 is arranged parallel to the bridge crane 2. A guide hopper 21 is installed at the discharge end of the first conveyor 6. The discharge end of the guide hopper 21 is located above the second conveyor 20, and the discharge end of the second conveyor 20 extends outside the material pool 1.

[0047] Specifically, please refer to Figure 3 and Figure 11 A scraper 22 and a brush 23 that contact the bottom of the conveyor belt on the first conveyor 6 are installed on the guide hopper 21.

[0048] Specifically, please refer to Figure 1 or Figure 2 A first track 24 extending outward from the top of the material pool 1 is provided at the top of the material pool 1. The bridge crane 2 is movably installed on the first track 24. A second track 25 is provided at the top of the bridge crane 2. The walking trolley 3 is movably installed on the second track 25. The first track 24 and the second track 25 are vertically arranged, and the bottom of the bridge crane 2 is higher than the top of the material pool 1; further, the width of the scraping plate 5 is the same as the width of the single-arm material taking mechanism; to ensure that both ends of the scraping plate 5 can respectively contact the two inner walls at the bottom inner wall of the material pool 1 and in the direction perpendicular to the traveling direction of the bridge crane 2.

[0049] Specifically, please refer to Figure 3 and Figure 9 Blade portions 26 are provided on both the scraping plate 5 and the baffle plate 13.

[0050] See Figures 13-14, regardless of whether a belt conveyor or a scraper conveyor is used for the material fetching boom 28 on the existing bridge-type double-arm material fetching machine 27, there is still a material fetching dead angle 31 between the material fetching end of the material fetching boom 28 and the inner bottom wall corner of the material pool 1. The inner bottom corner of the material pool 1 is extremely prone to moisture, and after the materials are not cleaned for a long time, consolidation or deterioration will occur, thus affecting the normal storage of the next batch of materials; while when the single-arm material fetching mechanism fetches materials, due to a large amount of materials gathering towards the material fetching end of the single-arm material fetching mechanism, it is easy to cause the first conveyor 6 to get stuck or overload and stop; by driving the scraping plate 5 to move through the bridge crane 2 and the traveling trolley 3 in this case, it is possible to clean the consolidated materials at one corner parallel to the traveling direction of the bridge crane 2 on the inner bottom wall of the material pool 1 and at the two corners perpendicular to the traveling direction of the bridge crane 2 (the corners of the area 30 where the single-arm material fetching mechanism cannot fetch materials); and the material fetching device can clean the consolidated materials at the other corner.

[0051] The specific working principle of the material fetching device is as follows:

[0052] When the material fetching device reaches the corner where materials are to be fetched, in the initial state, the output end of the first driving cylinder 10 is in a shortened state, the shovel plate shovels into the corresponding corner of the consolidated materials, the output end of the first driving cylinder 10 extends, the frame 9 rotates around the hinge point, and the baffle scraper 13 rotates synchronously with the frame 9 and breaks the consolidated materials at the corner from top to bottom. Subsequently, the output end of the second driving cylinder 11 extends, the U-shaped frame 12 drives the baffle scraper 13 to move synchronously, the bottom of the baffle scraper 13 always contacts the shovel plate and gradually moves up along the shovel plate, and the elastic support member 14 gradually contracts until the baffle scraper 13 scrapes the broken materials to the material fetching end of the first conveyor 6, realizing the fetching of the consolidated materials at this corner.

[0053] In this way, the residue of the consolidated materials at the inner bottom wall corner of the material pool 1 can be greatly reduced, and the material fetching dead angle 31 of this material fetching machine in the material pool 1 can be further reduced.

[0054] When the single-arm material fetching mechanism fetches materials during the process of traveling in the material pool 1 following the traveling trolley 3, the elongation amount of the output end of the first driving cylinder 10 can be adjusted to adaptively adjust the angle and distance between the shovel plate and the baffle scraper 13; a feeding channel is enclosed among the shovel plate, the baffle 8 and the baffle scraper 13 to adaptively adjust the size of the feeding channel, so as to adaptively adjust the amount of materials entering the material fetching end of the first conveyor 6, effectively reducing the incidence rate of the first conveyor 6 getting stuck or overloading and stopping due to the concentrated accumulation of materials towards the material fetching end of the first conveyor 6 and ensuring the smooth progress of the material fetching operation.

[0055] The materials conveyed by the single-arm material fetching mechanism enter the guide hopper 21, and the materials fall to the second conveyor 20 through the guide hopper 21. The second conveyor 20 conveys the materials to the outside of the material pool 1. The materials can be received by an external belt conveyor or a transfer device below the discharge end of the second conveyor 20 outside the material pool 1, so as to take out the materials in the material pool 1.

[0056] During the movement of the conveyor belt on the first conveyor 6, its bottom contacts the scraper 22 and the brush 23. The scraper 22 can scrape the materials attached to the conveyor belt into the material guiding hopper 21, and the brush 23 can further brush the materials at the conveyor belt to reduce the adhesion of the materials at the conveyor belt and avoid the influence on the material conveying effect due to too thick adhesion of the materials at the conveyor belt.

[0057] The first track 24 extends out of the material pool 1, so that the single-arm material taking mechanism and the scraping plate 5 can be infinitely close to the two inner walls of the material pool 1 perpendicular to the traveling direction of the bridge crane 2, thereby further reducing the material taking dead angle 31 of the single-arm material taking mechanism in the material pool 1, and the solidified materials at the corresponding corners can also be scraped off by the scraping plate 5.

[0058] The aged materials at the corners can be more smoothly scraped or chiseled through the blade part 26, improving the cleaning smoothness, cleaning efficiency and cleaning effect of the solidified materials at the corners, and reducing the residue of the solidified materials at the bottom corners of the material pool 1.

[0059] Embodiment 2

[0060] Further optimize the bridge-type single-arm material taking machine provided in Embodiment 1. Specifically, please refer to Figure 5 、 Figure 8 and Figure 12 , it further includes two third driving cylinders 15 installed on the shovel frame 7. The shovel plate includes two plate bodies 16 slidably installed on the shovel frame 7, and the two third driving cylinders 15 respectively provide power for the sliding of the two plate bodies 16; further, a slide rail is provided on the shovel frame 7, the plate body 16 is slidably installed on the slide rail, the third driving cylinders 15 are symmetrically installed on both sides of the shovel plate, and the output ends of the third driving cylinders 15 are fixedly connected to the plate body 16; the two third driving cylinders 15 can drive the two plate bodies 16 to synchronously move away from the center of the shovel plate.

[0061] Specifically, please refer to Figure 3 , it further includes a rotating frame 17 hingedly installed on the traveling trolley 3 and a fourth driving cylinder 18 providing power for the rotation of the rotating frame 17. The fourth driving cylinder 18 is hingedly installed on the traveling trolley 3, the output end of the fourth driving cylinder 18 is hinged to the rotating frame 17, and the first conveyor 6 is installed on the rotating frame 17.

[0062] Specifically, please refer to Figure 3 and Figure 10, the first conveyor 6 is slidably mounted on the rotary frame 17, and a lifting drive 19 for providing power for the up-and-down sliding of the first conveyor 6 is mounted on the rotary frame 17; further, the lifting drive 19 preferably uses a braking stepper motor, a gear and a rack. The rack is fixedly mounted under the first conveyor 6, the braking stepper motor is fixedly mounted on the rotary frame 17, the gear is fixedly mounted on the output end of the braking stepper motor, and the gear meshes with the rack; the lifting drive 19 can also use other equivalents such as a telescopic cylinder that can drive the first conveyor 6 to move up and down along the rotary frame 17; a clamping wheel is mounted on the first conveyor 6, and the clamping wheel is slidably mounted on the rotary frame 17.

[0063] When the walking trolley 3 moves along the bridge crane 2 towards the inner wall of the material pool 1 near the scraping plate 5 in this embodiment, the material in the material pool 1 cannot enter the feeding end of the first conveyor 6, and the single-arm feeding mechanism cannot perform the feeding operation; by starting the third driving cylinder 15, the output end of the third driving cylinder 15 shortens, and the two plate bodies 16 move away from each other to form an opening. The material enters the material channel formed by the shovel plate, the baffle 8 and the scraping plate 13 through the opening. Then start the second driving cylinder 11, the output end of the second driving cylinder 11 extends, and the U-shaped frame 12 drives the scraping plate 13 to move synchronously. The scraping plate 13 scrapes the material to the feeding end of the first conveyor 6. In this way, the feeding can be realized during the backward movement of the walking trolley 3 along the bridge crane 2, so that the single-arm feeding mechanism can continuously feed regardless of whether it is in the forward or backward state, greatly improving the feeding efficiency of the material in the material pool 1.

[0064] By adjusting the elongation of the output end of the fourth driving cylinder 18, the tilt angle of the rotary frame 17 can be adjusted, so as to adaptively adjust the tilt angle of the first conveyor 6. The inclination angle of the first conveyor 6 can increase the gravitational force of the material during the conveying process, making the material flow more easily, thereby improving the conveying capacity of the material. Especially for materials with high viscosity, increasing the inclination angle of the first conveyor 6 can effectively reduce the viscous resistance of the material, improve the conveying efficiency, and meet the conveying requirements of different materials.

[0065] By starting the braking stepper motor, the braking stepper motor drives the gear to rotate. After being transmitted by the rack, the first conveyor 6 can move downward along the rotary frame 17, so that the feeding end of the first conveyor 6 can gradually move deeper into the material pool 1 to gradually feed the material in the material pool 1 from top to bottom.

[0066] The use process of the bridge-type single-arm feeding machine provided by the present invention is as follows: Figure 2As a reference to the direction, the trolley 3 drives the single-arm reclaiming mechanism to move back and forth left and right along the first track 24 on the bridge crane 2, and the reclaimer cooperates with the action (the working principle of the reclaimer refers to the above), so that the single-arm reclaiming mechanism continuously and uninterruptedly reclaims the granular materials in the material pool 1 in the reclaimable area 29 of the single-arm reclaiming mechanism; at the same time, the output end of the multi-stage telescopic cylinder 4 extends, and the scraper plate 5 is inserted into the granular materials in the material pool 1 in the area 30 where the single-arm reclaiming mechanism cannot reclaim materials. During the movement of the trolley 3, the scraper plate 5 is driven The scraper plate 5 moves synchronously, and the material in the area where the single-arm feeding mechanism cannot take the material is scraped to the feeding area that the single-arm feeding mechanism can reach. The bridge crane 2 can drive the single-arm feeding mechanism to move forward and backward synchronously during the horizontal movement at the first track 24 on the top of the material pool 1, so that the single-arm feeding mechanism can move in the material pool 1 to fully cover the area 29 where the single-arm feeding mechanism can take the material, so as to realize the feeding of the granular material in the material pool 1 in the entire area. The principle and process of taking the material at the corners of the bottom wall of the material pool 1 can be found in Example 1, and will not be further elaborated here.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.
