Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveying equipment, in particular to a scraper conveying mechanism for mining. Background Art

[0002] Scraper conveyor is a common conveying equipment, mainly used in mineral mining projects, to transfer the collected and crushed ore and other materials to a predetermined location, and can be used in raw ore mining and further crushing of ore. Most existing scraper conveyors directly fix the scraper, and two opposing scrapers and a flat plate below form a storage area or storage space for storing ore. In actual use, due to the different types of mining, mining processes and requirements, during transportation, the scraper spacing is too small and the ore is stuck, or the spacing is too large to be fully filled, resulting in ore and other raw materials concentrated in the center between the two scrapers, or even towering and overflowing from the scraper, and cannot fully fill the area between the two scrapers, resulting in low transportation efficiency.

[0003] In addition, traditional scraper conveyors mostly use chain plates and sprockets for meshing and conveying, which makes the length of each chain plate very limited, and a flat plate must be placed under the scraper and laid in the horizontal direction as a carrier for the ore, and the structure is relatively complex. Utility Model Content

[0004] The utility model aims to provide a mining scraper conveying mechanism, which solves the problems in the prior art that the scraper conveyor has a complex structure, the storage area cannot be adjusted, and the transportation efficiency needs to be further improved.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A mining scraper conveying mechanism comprises a scraper 2, a driving wheel 3 and a chain plate 4. The driving wheel 3 is provided with the chain plate 4, and the chain plate 4 is composed of a plurality of chain plate bodies hinged together by hinge columns 6. The scraper 2 is vertically arranged on the chain plate 4. The rim of the driving wheel 3 is evenly distributed with a plurality of arc-shaped notches along the axial direction on the circumference. When the driving wheel 3 rotates, the arc-shaped notches are engaged with the hinge columns 6 one by one to drive the chain plate 4 to rotate accordingly.

[0007] A group of scrapers 2 are vertically arranged on the upper sides of the left and right ends of a group of chain plate bodies of the chain plate 4. A group of scrapers 2 consists of a fixed scraper and a movable scraper 201. The fixed scraper is fixed on the chain plate 4, and the movable scraper 201 is driven by the screw mechanism 1.

[0008] The screw mechanism 1 includes a screw 8, a threaded sleeve 9, a connecting arm 10 and a bevel gear 11. The screw 8 is arranged inside the chain plate body along the length direction of the chain plate 4. The bevel gear 11 is fixed to one end of the screw 8. The threaded sleeve 9 is threadedly mounted on the screw 8. The connecting arm 10 is in a "﹁" shape, one end of which is fixed to the threaded sleeve 9, and the other end is fixed to the bottom end of the corresponding movable scraper 201, and the bottom end of the movable scraper 201 is slidably mounted along the length direction of the chain plate 4.

[0009] The bevel gear 11 is meshed with a bevel gear 13, and a transmission sprocket 12 is coaxially fixed to the bevel gear 13. The transmission sprocket 12 is located on the outside of the chain plate 4, and the rotating shaft of the transmission sprocket 12 is rotatably installed on the side of the chain plate 4. All the transmission sprockets 12 are driven by a chain 14, so that when all the transmission sprockets 12 rotate, the movable scrapers 201 on all the scrapers 2 move accordingly.

[0011] It also includes a pair of baffles 16 , which are located at the front and rear sides of the chain plate 4 at an upper horizontal position and are in sliding contact with the chain plate 4 .

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

[0025] Example 1

[0026] like Figure 1-7The present embodiment provides a mining scraper conveying mechanism, including a scraper 2, a driving wheel 3 and a chain plate 4. The driving wheel 3 is provided with a chain plate 4, and the chain plate 4 is composed of a plurality of chain plate bodies hinged together by hinged columns 6 so as to be wound around the driving wheel 3 and change direction. The scraper 2 is vertically arranged on the chain plate 4, and a plurality of arc-shaped notches along the axial direction are evenly distributed on the circumference of the rim of the driving wheel 3, and each arc-shaped notch is semicircular. When the driving wheel 3 rotates, the arc-shaped notches are engaged with the hinged columns 6 one by one, that is, there is always a hinged column 6 just located in the arc-shaped notch, so as to drive the chain plate 4 to rotate accordingly, that is, the chain plate 4 is wound around the driving wheel 3, and the scraper 2 is reliably transmitted with a simple and effective result.

[0027] A group of scrapers 2 are vertically arranged on the upper sides of the left and right ends of a group of chain plate bodies of the chain plate 4. A group of scrapers 2 consists of a fixed scraper and a movable scraper 201. The fixed scraper is fixed on the chain plate 4, and the movable scraper 201 is driven by the screw mechanism 1.

[0028] Specifically, the scraper 2 adopts a two-piece scraper overlapping structure. The movable scrapers 201 opposite to each other in the two scrapers 2 on each chain plate 4 are synchronously driven by the same screw mechanism 1 to move closer to or away from each other. When it is necessary to adjust the storage area on each chain plate 4, the screw mechanism 1 is turned on to bring the movable scrapers 201 opposite to each other closer to each other, so that the original storage area can be divided into three sub-areas to adapt to the transportation of specific ores. When the ore size is large, only one storage area is set to prevent the ore from being stuck between the two scrapers 2 and not falling. The bottom of the storage area where the chain plate 4 is located causes insufficient filling; when the ore is relatively fine, three sub-areas can be set, that is, the original storage area is divided into three sub-areas, so as to increase the transmission speed of the chain plate 4 and try to keep the sub-areas fully filled. If three sub-areas are not set, it may cause the chain plate 4 to transmit slowly or the ore to be unevenly distributed, because it is difficult to fully fill a storage area too quickly, or the ore in the storage area is piled too high, which has exceeded the vertical height of the scraper 2, but the storage area is still not full and the ore is overly concentrated.

[0029] The screw mechanism 1 includes a screw 8, a threaded sleeve 9, a connecting arm 10 and a bevel gear 11. The screw 8 is arranged inside the chain plate body along the length direction of the chain plate 4. The bevel gear 11 is fixed to one end of the screw 8. The threaded sleeve 9 is threadedly mounted on the screw 8. The connecting arm 10 is in a "﹁" shape. The reason for the "﹁" shape is to make the screw 8 as short as possible so that it can be located as a whole inside the chain plate 4 for easy transmission. One end of the connecting arm 10 is fixed to the threaded sleeve 9, and the other end is fixed to the bottom end of the corresponding movable scraper 201, and the bottom end of the movable scraper 201 is installed in a sliding manner along the length direction of the chain plate 4 to change the layout of the above-mentioned storage area.

[0030] The bevel gear 11 is meshed with the bevel gear 13, and a transmission sprocket 12 is coaxially fixed to the bevel gear 13. The transmission sprocket 12 is located outside the chain plate 4, and the rotating shaft of the transmission sprocket 12 is rotatably mounted on the side of the chain plate 4. All the transmission sprockets 12 are driven by the chain 14, so that when all the transmission sprockets 12 rotate, the movable scrapers 201 on all the scrapers 2 move accordingly. This makes the conveying units of the scraper 2 conveyor more densely distributed, which is conducive to full transportation.

[0031] like Figure 2 When every three adjacent chain plates 4 are in a horizontal plane, a rectangular concave cavity 5 is formed on the bottom surface thereof. The depth and length of the cavity 5 must ensure that when the driving wheel 3 rotates, the wheel rim does not contact the inner wall of the cavity 5 to maintain the normal rotation of the driving wheel 3. At this time, the chain plate 4 is an independent rectangular plate, and the ore can be directly placed on the chain plate 4.

[0032] A group of chain plate bodies of the chain plate 4 includes two parallel front and rear plates. The distance between the front and rear plates is greater than the length of the driving wheel 3. The driving wheel 3 is located between the front and rear plates. A receiving plate 15 is installed below the chain plate 4 at the upper horizontal position to slide with it, so that the ore is received by the receiving plate and transported forward. The receiving plate 15 is independently fixed below the chain plate 4 at the upper horizontal position. The chain plate 4 slides on the receiving plate 15, and the scraper 2 fixed on the chain plate 4 drives the ore falling on the receiving plate to move. Compared with the existing conveyor in which the entire chain plate is a complete plate for receiving ore, the scraper conveying mechanism only sets a receiving plate at the upper horizontal position for receiving the ore, so that the conveying mechanism has a simple structure, light weight, less consumables, and is more economical and practical.

[0033] Specifically, in order to maintain the normal rotation of the driving wheel 3, its chain plate 4 includes a front plate and a rear plate that are arranged parallel to each other and spaced apart. The two plates are spaced apart, and the left and right adjacent front plates and the left and right adjacent rear plates that are opposite to each other are hinged together through a hinge column, similar to a bicycle chain, so that when the driving wheel 3 rotates, the rim of the driving wheel 3 passes between the front and rear plates.

[0034] In order to form a rectangular storage bin for holding ore, such as Figure 7 The conveying mechanism further includes a pair of baffles 16, which are located at the front and rear sides of the chain plate 4 at the upper horizontal position along the horizontal moving direction of the chain plate 4 and are in sliding contact with the chain plate 4. That is, the two baffles 16 are independently fixed at the left and right sides of the chain plate 4 at the upper horizontal position, and the chain plate 4 slides between the two baffles 16, thereby preventing the ore from sliding off the front and rear sides of the chain plate.

[0035] In the utility model, a driven wheel is also included. The driven wheel and the driving wheel 3 are respectively arranged at the left and right ends of the chain plate 4 to tighten the chain plate 4. When the motor drives the driving wheel 3 to rotate, the evenly distributed arc-shaped notches on the rim of the driving wheel 3 are engaged with the hinge columns 6 one by one, thereby driving the chain plate 4 to rotate accordingly.
