Description
Technical Field
The utility model relates to the technical field of ore feeding, in particular to a modified chain plate for a heavy plate feeder.
Background
The plate feeder is a mechanical device driven by a chain wheel and a chain, and is mainly used for continuously and evenly distributing and transferring materials for a crusher or other working machines. From the application, the device is suitable for conveying bulk or large bulk materials in a short distance, and is widely used in industries of metallurgy, mining, electric power, machinery, construction and the like, and the device is characterized by large conveying capacity, heavy load at low speed and large driving torque. Depending on the conveying capacity, the plate feeders can be classified into light, medium and heavy type, and heavy plate feeders are most commonly used in mining industry nowadays, and can be used in situations of severe working conditions such as damp, cold, high temperature, dust and the like.
Fig. 1 shows an example of a pallet feeder, which, from a constructional point of view, mainly consists of a steel frame, a supporting mechanism, a drive, a chain drive, a spindle support and other accessory mechanisms. When the chain plate conveying device works, the motor drives the driving chain wheel to rotate through the coupler, the speed reducer and the like, then drives the chain to move, and the chain plate fixedly connected with the chain bears materials and moves along with the chain, so that the purpose of conveying the materials is realized.
Because the conveying working surface of the plate feeder is formed by splicing a plurality of chain plates, the gap between the chain plates can have the problem of ore leakage. In response to this problem, a link plate of the double circular arc plate overlap type has been developed. As proposed in patent document CN 219822618U. The chain plate comprises a bottom plate, side baffles, vertical ribs, strip-shaped bosses, arc-shaped bosses, supporting bosses, arc-shaped grooves and reinforcing ribs, wherein the arc-shaped grooves are formed in the non-working surface of the bottom plate at one end of the chain plate in the length direction, the arc-shaped bosses are arranged on the working surface of the bottom plate at the other end, and after a plurality of chain plates are assembled, the big ends of the front chain plates and the small ends of the rear chain plates in the material direction are in lap joint. The chain plate with the structure can effectively reduce the leakage amount, but has the defects that on one hand, the pressed circular arc occupies most of the dimension of the chain plate in the width direction, so that the flat section for installing the chain plate is small; on the other hand, because the connecting plate needs to be overlapped with other chain plates, the requirement on the dimensional accuracy of the chain plates is higher, the precise casting process is adopted for manufacturing, the dimensional error of the chain plates and the connection rationality are ensured, and the manufacturing cost is increased.
In view of the above, there is still a great room for improvement in the link plates of existing plate feeders.

In order to solve the problem of material leakage, chain plates in the form of double circular arc plates are developed at present. The chain plate with the structure can effectively reduce the leakage amount, but has the defects that on one hand, the pressed circular arc occupies most of the dimension of the chain plate in the width direction, and the installed flat section is small; on the other hand, because the connecting plate needs to be overlapped with other chain plates, the requirement on the dimensional accuracy of the chain plates is higher, the precise casting process is adopted for manufacturing, the dimensional error of the chain plates and the connection rationality are ensured, and the manufacturing cost is increased.
To this end, the present utility model provides a retrofit link plate for a heavy duty plate feeder. Fig. 2 shows a front view of a modified link plate in accordance with an embodiment of the present utility model, fig. 3 is a side view of the modified link plate, and fig. 4 is a sectional view of the modified link plate of fig. 2 taken along the line A-A.
Referring to fig. 2-4, a retrofit flight for a heavy duty apron feeder generally includes a bottom plate 10, side dams 12 at both ends, a slag trap 14, and an arcuate plate 18.
The bottom plate 10 is a main structure of the whole chain plate and is used for receiving conveyed ore and driving the ore to be conveyed to a set position. The shape of the bottom plate 10 is generally rectangular plate-like. Because of the heavier bearing ore, the base plate 10 is generally required to have a certain resistance to abrasion and crushing. For this purpose, the base plate 10 may be made of Q355 steel plate having a thickness of 20 to 25 mm.
In order to prevent leakage from both sides of the link plate, side guards 12 are provided at both ends in the longitudinal direction of the link plate (i.e., the left-right direction in the drawing). The side guards 12 may include a first pair of side guards spaced apart at a first pitch and a second pair of side guards spaced apart at a second pitch, the first pitch being greater than the second pitch, and the first pair of side guards and the second pair of side guards being at different width positions of the bottom panel 10. As shown in fig. 2, the first pair of side guards includes two first side guards 12a (also referred to as outer side guards), and the second pair of side guards includes two second side guards 12b (also referred to as inner side guards), with a gap between the first side guards 12a and the second side guards 12b of 5-7 mm on each side. As can be seen from the figure, the mounting positions of the first side baffle 12a and the second side baffle 12b are staggered in the length direction, with a predetermined gap reserved therebetween. The first side baffle 12a and the second side baffle 12b have an overlap region in the width direction, the width of the overlap region being 20mm or more to ensure that mineral aggregate does not leak from the intersection of the two. The first side barrier 12a extends beyond the widthwise edge (upper edge shown) of the bottom panel 10a by a projection size of about 10mm, and the second side barrier 12b also extends beyond the widthwise edge (lower edge shown) of the bottom panel 10a by a projection size of about 10mm.
The shape of the bottom plate 10 is also optimized in correspondence with the structure of the side guards 12. As shown in fig. 2, the base plate 10 includes a first section 10a and a second section 10b, the first section 10a having a length greater than that of the second section 10b and being stepped at the junction of the two. Two first side guards 12a are mounted at both ends of the first section 10a, and two second side guards 12b are mounted at both ends of the second section 10 b.
Through this setting, when a plurality of link joint are installed side by side, the outer panel of one link joint can extend to the outside of another link joint inner panel, encloses the lateral part better, prevents to leak the material. In addition, the baffles on two sides are changed into two independent plates, the installation positions, the sizes and the like of the baffles are optimized, the shape of the bottom plate 10 is optimized in a coordinated manner, the side plates can be used for blocking edge leakage, problems of the side baffles during engagement between the chain plates can be avoided, the whole chain plates deform due to extrusion deformation, the risk of engagement deformation between the chain plates is effectively reduced, and the leakage risk is further reduced.
The slag plate 14 is provided at one end (at the lower end in fig. 2) of the bottom plate 10 in the width direction, and the slag plate 14 serves to block a gap between two adjacent link plates when the link plates are side by side or are bent in a back-to-back manner. As shown in fig. 4, a slag trap 14 is attached to the upper surface of the floor, at least a portion of the slag trap 14 extending beyond the edge of the floor 10 and overlapping over the floor of another link plate (shown in phantom in fig. 4) in use. Typically, a gap of about 4mm exists between two adjacent link plates, and the width of the portion of the slag plate 14 extending beyond the edge of the bottom plate 10 is 6mm or more in order to sufficiently block the gap between the two link plates. The existing chain plate is generally not provided with such a slag blocking structure, when the chain plate reciprocates on the head and tail wheels, the condition that an oversized gap is generated between the chain plate and the chain plate occurs, after the gap is generated, the heavy plate can leak ores and accumulate, so that the accumulated ores can accumulate at the tail part infinitely, and overlarge loads are caused on the tail wheels, the tensioning devices, the chain rails and other parts. The slag trap 14 of the utility model can effectively shield the gap between two adjacent chain plates, thereby effectively avoiding slag from entering the gap between the chain plates and reducing the loads of a plurality of parts such as a tail wheel tensioning device.
Alternatively, the slag trap 14 includes a plurality of slag traps closely spaced along the length of the bottom plate 10, and 4 slag traps 14 are employed in the example shown in fig. 2. When the partial abrasion and deformation occur in the 4 slag baffles, the damaged slag baffle 14 can be repaired or replaced independently without replacing all the slag baffles 14, so that the maintenance cost of spare parts is reduced, and the operation is convenient.
As shown in fig. 4, an arcuate plate 18 is attached to the lower surface of the bottom plate 10 and is located directly below the slag trap 14. The arcuate plate 18 includes a portion extending away from the widthwise midline of the base plate 10 and beyond the edge of the base plate 10, i.e., a portion protruding to the outside of the base plate 10. When assembled with another link plate, the protruding portion of the arc plate 18 extends below the other link plate. Because the arc-shaped plate 18 is below the bottom plate and does not bear the impact of ores, the strength requirement is low, and a steel plate with the thickness of 10mm is generally selected for welding with the bottom plate, so that the manufacturing cost is low. Providing an arcuate plate 18 below the base plate 10 further prevents leakage. The base plate 10 is further provided with mounting aids 16 for mounting the base plate 10 to a corresponding support structure.
The modified chain plate has the advantages of simple structure, low accuracy in machining dimension, easiness in machining and manufacturing and low cost.
The preferred embodiments of the present utility model have been described in detail hereinabove, but the present utility model is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solutions of the present utility model within the scope of the technical concept of the present utility model, and these simple modifications all fall within the scope of the present utility model.
In addition, the specific features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described further.
Moreover, any combination of the various embodiments of the utility model can be made without departing from the spirit of the utility model, which should also be considered as disclosed herein.
