It is mainly used for feeding bulk materials, with stable feeding speed, adjustable feeding speed, and uniform and continuous feeding. Heavy-duty plate chain feeder is particularly suitable for short-distance conveying of materials with large particle size or weight;

[0003] However, existing feeders often encounter a series of problems in the process of conveying a large amount of materials, which affect the normal operation and efficiency of the feeder to a certain extent: first, the conveying capacity of the feeder is insufficient, which makes it difficult to meet production needs when processing a large amount of materials, thus affecting the overall production progress; secondly, the feeder is prone to blockage during operation, which not only reduces the material conveying speed, but also may cause equipment damage; in addition, the leakage problem is also a major problem for the feeder, which not only causes material waste, but also may pollute the environment; at the same time, the maintenance cost of the feeder is relatively high, and frequent repairs and maintenance bring a considerable economic burden to the enterprise; finally, the feeder body and chain plate are prone to deformation under long-term high-intensity work, which not only affects the normal operation of the equipment, but also may shorten the service life of the equipment; therefore, it is very necessary to provide a heavy-duty plate chain feeder with reasonable design, low maintenance cost, strong conveying capacity, convenient disassembly and assembly, avoidance of conveying blockage and leakage, and long service life.

[0025] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0026] like Figure 1-7 As shown, a heavy-duty plate chain feeder includes a frame 5, a driving shaft 4 is arranged on the left side of the frame 5, a passive shaft 10 is arranged on the right side of the frame 5, an annular chain 8 is arranged on the front and rear sides of the frame 5, and a plurality of chain support wheels 6 are arranged on the inner side of the chain 8 toward the frame 5. The arrangement of the chain support wheels 6 can avoid the phenomenon of sagging when the chain 8 moves, thereby improving the conveying efficiency of the feeder. The chain support wheels 6 can roll around the frame 5 on the frame 5 in a circular manner, and a plurality of chain plates 9 are laid on the chain 8, and the chain plates 9 are connected by snaps. The chain plate 9 is tightly wrapped around the driving shaft 4 and the passive shaft 10 on both sides of the frame 5. One end of the driving shaft 4 is connected to the coupling 3, the other end of the coupling 3 is connected to the reducer 2, and the other end of the reducer 2 is connected to the motor 1. Support seats 13 are provided at both ends of the passive shaft 10, and a fixed track 1302 is provided at the bottom end of the support seat 13. The bottom end of the passive shaft 10 is embedded in the fixed track 1302 and can slide left and right in the fixed track 1302. An adjusting screw rod 12 is threadedly connected to the right side of the passive shaft 10, and a butterfly spring 11 is passed through the right side of the adjusting screw rod 12.

[0027] A shield 7 is provided on the upper part of the chain plate 9 at the upper end of the frame 5, and the butterfly spring 11 is provided on the outer side of the frame 5, with one end fixedly connected to the frame 5 and the other end fixedly connected to the adjusting screw rod 12 through a nut.

[0028] The setting of the guard 7 can shield the materials conveyed on the chain plate 9 to avoid contamination or damage of the materials. The setting of the butterfly spring 11 can buffer the impact of large pieces of materials on the frame 5 and the chain plate 9, thereby improving the conveying capacity and stability of the feeder.

[0029] Among them, rectangular protrusions 1001 are fixed at both ends of the passive shaft 10, the adjusting screw rod 12 is threadedly connected to the rectangular protrusion 1001, a groove 1301 is opened at the top of the support seat 13, the top of the rectangular protrusion 1001 is just embedded in the groove 1301, and the bottom end of the rectangular protrusion 1001 is embedded in the fixed track 1302 of the support seat 13, and a plurality of balls 14 are laid on the bottom layer of the fixed track 1302, and the rectangular protrusion 1001 can slide left and right on the balls 14.

[0030] The setting of the groove 1301 can improve the stability of the equipment operation and avoid the misalignment of the passive shaft 10 during operation. By setting a fixed track 1302 and a ball 14 structure in the support seat 13, when the rectangular protrusion 1001 slides left and right on the ball 14 of the fixed track 1302, the friction resistance of the rectangular protrusion 1001 and the passive shaft 10 when moving left and right in the fixed track 1302 can be reduced, thereby reducing the noise generated during the operation of the equipment, improving the service life of the equipment and the stability of the overall operation of the equipment, and at the same time, it is more labor-saving when rotating the adjustment screw 12.

[0031] The chain plate 9 is formed by one-time stamping of thickened manganese plate, and the end of the chain plate 9 is an arc-shaped bending structure, and a buckle 15 is provided at the arc-shaped bending position, and the chain plates 9 are connected by the buckle 15 to form a buckle connection.

[0032] The chain plates 9 are connected by snap-fits, and the ends of the chain plates 9 are of an arc-shaped bending structure. The arc-shaped surfaces between the chain plates 9 are tightly buckled, which can effectively prevent fine materials from leaking into the frame 5. At the same time, they have strong anti-clogging ability and can effectively prevent material blockage. When a chain plate 9 is damaged, only one of them needs to be replaced without all of them being removed, which greatly reduces the maintenance cost. The disassembly and replacement are relatively convenient, and the downtime is short. At the same time, the chain plate 9 is formed by one-time stamping of thickened manganese plate, which can withstand the impact of large pieces of material and improve the conveying capacity of the feeder.

[0033] The frame 5 is formed by one-time welding and is annealed after welding to eliminate stress. The purpose of this design is to extend the service life of the equipment and the stability during operation. The annealing treatment can effectively eliminate these internal stresses, so that the frame 5 maintains a stable shape and size during long-term use.

[0034] The working principle of the utility model is as follows:

[0035] When the utility model is in use, the motor 1 is started, and the motor 1 reduces the speed of the power through the speed reducer 2, and then transmits the power to the driving shaft 4 through the coupling 3. The driving shaft 4 rotates and drives the chain plate 9 to make a circular motion. When a chain plate 9 is damaged, only one of them needs to be replaced, and there is no need to remove all of them. When it is found that the chain plate 9 is loose during movement, the adjusting screw rod 12 can be rotated to adjust the screw rod 12, which is threadedly connected to the rectangular protrusion 1001, and then the rectangular protrusion 1001 and the passive shaft 10 can be driven to move to the right to tighten the sprocket. Conversely, when it is found that the chain plate 9 is too tight, the adjusting screw rod 12 can be rotated in the opposite direction to loosen the sprocket.

[0036] In general, the utility model has reasonable design, low maintenance cost, strong conveying capacity, convenient disassembly and assembly, avoids conveying blockage and material leakage, prolongs the service life of the feeder, and improves the stability of the feeder operation.
