Description

A modified chain plate for heavy-duty plate feeder

Technical Field

The utility model relates to the technical field of ore feeding, and more specifically to a modified chain plate for a heavy-duty plate feeder.

Background technique

Plate feeder is a mechanical device driven by sprocket chain, mainly used for continuous and uniform distribution and transfer of materials in crushers or other working machinery. Considering the application occasion, it is more suitable for short-distance conveying of bulk or large block materials, so it is widely used in metallurgy, mining, electricity, machinery, construction and other industries. Its biggest feature is large conveying capacity, low speed and heavy load and large driving torque. According to the different conveying capacity, plate feeder can be divided into three types: light, medium and heavy. The most commonly used in the mining industry today is the heavy plate feeder, which can be used in places with harsh working conditions such as humidity, cold, high temperature, dust, etc.

Figure 1 shows an example of an apron feeder. From the structural composition, the apron feeder is mainly composed of a steel structure frame, a support mechanism, a drive device, a chain transmission system, a main shaft support device and other auxiliary mechanisms. When working, the motor drives the active sprocket to rotate through a coupling, a reducer, etc., and then drives the chain to move forward. The chain plate fixed with the chain carries the material and moves with the chain to achieve the purpose of conveying the material.

Since the conveying working surface of the plate feeder is composed of multiple chain plates, the gap between the chain plates will cause leakage of ore. In response to this problem, a chain plate with double arc plate overlap has been developed. For example, the chain plate proposed in patent document CN 219822618U. This chain plate includes a bottom plate, a side baffle, a vertical rib, a long strip boss, an arc boss, a support boss, an arc groove, and a reinforcing rib. The non-working surface of the bottom plate at one end of the chain plate along the length direction is provided with an arc groove, and the working surface of the bottom plate at the other end is provided with an arc boss. After the multiple chain plates are assembled, the large head of the previous piece and the small head of the next piece are overlapped and assembled along the material direction. Although the chain plate of this structure can effectively reduce the amount of leakage, it still has shortcomings. On the one hand, the pressed arc will occupy most of the width direction of the chain plate, resulting in a small flat section for installing the chain plate; on the other hand, due to the need to overlap with other chain plates, the chain plate has high dimensional accuracy requirements, and it needs to be manufactured using a precision casting process to ensure the dimensional error of the chain plate and the rationality of the connection, which increases the manufacturing cost.

In view of the above situation, there is still a lot of room for improvement in the chain plates of existing apron feeders.

In order to solve the problem of material leakage, a double arc plate overlapped chain plate has been developed. Although this type of chain plate can effectively reduce the amount of material leakage, it still has some shortcomings. On the one hand, the pressed arc takes up most of the chain plate width, and the flat section for installation is small; on the other hand, due to the need to overlap with other chain plates, the chain plate has high dimensional accuracy requirements, and it needs to be manufactured using precision casting technology to ensure the dimensional error of the chain plate and the rationality of the connection, which increases the manufacturing cost.

To this end, the utility model provides a modified chain plate for a heavy-duty plate feeder. FIG2 shows a front view of a modified chain plate according to an embodiment of the utility model, FIG3 is a side view of the modified chain plate, and FIG4 is a cross-sectional view of the modified chain plate of FIG2 along line A-A.

2-4 , the modified chain plate for a heavy-duty plate feeder generally includes a bottom plate 10 , side baffles 12 at both ends, a slag baffle plate 14 , and an arc-shaped plate 18 .

The bottom plate 10 is the main structure of the entire chain plate, which is used to receive the ore and drive the ore to the set position. The bottom plate 10 is generally in the shape of a rectangular plate. Due to the heavy ore, the bottom plate 10 is generally required to have a certain wear resistance and smash resistance. For this reason, the bottom plate 10 can be made of Q355 steel plate with a thickness of 20 to 25 mm.

In order to avoid material leakage on both sides of the chain plate, side baffles 12 are arranged at both ends of the chain plate in the length direction (i.e., the left and right directions shown in the figure). The side baffles 12 may include a first pair of side baffles separated by a first spacing and a second pair of side baffles separated by a second spacing, the first spacing is greater than the second spacing, and the first pair of side baffles and the second pair of side baffles are at different width positions of the bottom plate 10. As shown in FIG. 2 , the first pair of side baffles include two first side baffles 12a (also referred to as outer side baffles), and the second pair of side baffles include two second side baffles 12b (also referred to as inner side baffles), and the gap between the first side baffle 12a and the second side baffle 12b on each side is 5 to 7 mm. As can be seen from the figure, the installation positions of the first side baffle 12a and the second side baffle 12b are staggered along the length direction, and a predetermined gap is reserved between the two. The first side baffle 12a and the second side baffle 12b have an overlapping area in the width direction, and the width of the overlapping area is more than 20 mm to ensure that the mineral material will not leak from the intersection of the two. The first side baffle 12a extends beyond the edge of the bottom plate 10a in the width direction (the upper edge shown in the figure), and the protruding dimension is about 10mm. The second side baffle 12b also extends beyond the edge of the bottom plate 10a in the width direction (the lower edge shown in the figure), and the protruding dimension is about 10mm.

Corresponding to the structure of the side baffles 12, the shape of the bottom plate 10 is also optimized. As shown in FIG2 , the bottom plate 10 includes a first section 10a and a second section 10b. The length of the first section 10a is greater than the length of the second section 10b and a step is formed at the connection between the first section 10a and the second section 10b. Two first side baffles 12a are installed at both ends of the first section 10a, and two second side baffles 12b are installed at both ends of the second section 10b.

Through such an arrangement, when multiple chain plates are installed side by side, the outer plate of one chain plate will extend to the outer side of the inner plate of another chain plate, better enclosing the side and preventing material leakage. Moreover, the utility model changes the baffles on both sides into two independent plates, optimizes their installation positions and dimensions, and coordinately optimizes the shape of the bottom plate 10, which can not only use the side plates to block edge leakage, but also avoid problems with the side baffles when the chain plates are meshed, and the extrusion deformation causes the entire chain plate to deform, effectively reducing the risk of meshing deformation between the chain plates, and further reducing the risk of material leakage.

The slag blocking plate 14 is arranged at one end in the width direction of the bottom plate 10 (at the lower end in FIG. 2 ). The slag blocking plate 14 is used to block the gap between two adjacent chain plates when the chain plates are arranged side by side or when the chain plates are bent at the head and tail ends. As shown in FIG. 4 , the slag blocking plate 14 is connected to the upper surface of the bottom plate. At least a portion of the slag blocking plate 14 extends beyond the edge of the bottom plate 10 and overlaps the bottom plate of another chain plate (shown by the dotted line in FIG. 4 ) when in use. Generally, there is a gap of about 4 mm between two adjacent chain plates. In order to fully block the gap between the two chain plates, the width of the portion of the slag blocking plate 14 extending beyond the edge of the bottom plate 10 is more than 6 mm. Existing chain plates usually do not have such a slag blocking structure. When the chain plates reciprocate between the head and tail wheels, there will be a situation where there is an excessive gap between the chain plates. After the gap is generated, the ore will leak out and accumulate in the heavy plate, resulting in unlimited accumulation of ore at the tail, causing excessive loads on the tail wheel, the tensioning device, the chain rail and other parts. The slag blocking plate 14 of the utility model can effectively block the gap between two adjacent chain plates, thereby effectively preventing slag from entering the gap between the chain plates and reducing the load on multiple parts such as the tail wheel tensioning device.

Optionally, the slag stopper 14 includes a plurality of slag stopper plates closely arranged along the length direction of the base plate 10. In the example shown in FIG2 , a total of four slag stopper plates 14 are used. If any of the four slag stopper plates is partially worn or deformed, the damaged slag stopper plate 14 can be repaired or replaced individually without replacing all of the slag stopper plates 14, thereby reducing the spare parts maintenance cost and facilitating operation.

As shown in Figure 4, the arc plate 18 is connected to the lower surface of the bottom plate 10 and is located directly below the slag retaining plate 14. The arc plate 18 includes a portion extending away from the center line of the bottom plate 10 in the width direction and beyond the edge of the bottom plate 10, that is, a portion protruding to the outside of the bottom plate 10. When assembled with another chain plate, the protruding portion of the arc plate 18 extends to the bottom of the other chain plate. Since the arc plate 18 is below the bottom plate and does not withstand the impact of ore, its strength requirement is low. Generally, a 10 mm thick steel plate is selected to be welded to the bottom plate, and the manufacturing cost is low. The arrangement of the arc plate 18 below the bottom plate 10 can further prevent material leakage. The bottom plate 10 is also provided with an installation auxiliary part 16, which is used to install the bottom plate 10 to the corresponding supporting structure.

The modified chain plate of the utility model has a simple structure and shape, has low precision requirements on processing dimensions, is easy to process and manufacture, and has low cost.

The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
