Description

Technical Field

[0001] The utility model relates to the technical field of plate feeders, and specifically relates to a new type of plate feeder. Background Technique

[0002] In recent years, with the wide application of feeding equipment in industries such as coal, ore dressing plants, mines, chemical industry, cement, and building materials, as a feeding equipment, the plate feeder is an indispensable equipment in the material conveying system. The feeding amount of the new type of plate feeder can be dynamically and continuously adjusted, making the feeding system more capable of meeting the requirements of high efficiency, energy conservation, and environmental protection.

[0003] Chinese Patent Application No. 202410628114.4 discloses a plate feeder and a feeding method, including a frame body, a transmission chain, and a number of receiving plates arranged on the transmission chain. The receiving plates are provided with a number of sieve holes for screening materials, which solves the problem that dust accumulates during long-term use of the feeder in the prior art and affects the use of the equipment. The receiving plate of this plate feeder is a conventional structure. Due to the need for an effective chain plate support structure, it can only convey fine powder-like materials, with a small bearing capacity and cannot meet the conveying of materials such as ores and building materials. Similarly, Chinese Patent Application No. 202022714821.5 discloses a plate feeder. The conveying mechanism includes a chain plate, a baffle, a rod body arranged on the chain plate, a connecting plate arranged on the rod body, and an installation groove arranged on the chain plate. The conveying mechanism completely relies on the first idler and the second idler for bearing, lacking an effective walking support structure, with an effective bearing capacity and unable to meet the actual use requirements. Therefore, a new type of plate feeder is proposed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of plate feeder. The guide rail plays a role in supporting the second chain plate walking wheel and supports both ends of the chain plate to ensure the stable operation of the chain plate, reduce noise, and at the same time improve the bearing capacity of the chain plate, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of plate feeder, including a frame, a head wheel set, a tail wheel set, a chain plate, and a chain. The left end and the right end of the frame are respectively provided with a tail wheel set and a head wheel set. The chain is arranged between the tail wheel set and the head wheel set.

Second chain plate walking wheels are arranged on the fixed shafts. Guide rails are arranged on the frame. The second chain plate walking wheels are in rolling contact with the guide rails. Scale plates are arranged at both ends of the chain plate. A tensioning device is arranged at the left end of the frame. The tensioning device and the tail wheel set are designed as a whole. The tensioning device includes a pull rod and a spring. The pull rod passes through the outside of the frame, and the spring is arranged on the pull rod.

[0006] Further, an upper reinforcing plate is provided on the upper surface of the middle part of the chain plate, a lower reinforcing plate is provided on the lower surface of the middle part of the chain plate, and a first chain plate traveling wheel is provided on the lower surface of the lower reinforcing plate. The first chain plate traveling wheel is in rolling contact with the guide rail.

[0007] Further, an outer baffle is provided on the pull rod. The outer baffle is arranged on the outer side of the frame. Two adjusting nuts are provided on the pull rod.

[0008] Further, a driving device for driving the head wheel set is provided on the side surface of the frame, and the driving device adopts a variable-frequency speed-regulating three-phase asynchronous motor.

[0009] Further, the upper reinforcing plate, the chain plate and the lower reinforcing plate are fixed to each other by bolts or welding.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The scale plate and the chain plate traveling wheels of the present utility model are connected by a chain. The overall design structure is compact and the sealing is tight, improving the impact resistance and wear resistance of the chain plate. The tensioning device plays a role in tensioning, ensuring that the chain is in a tensioned state during operation and preventing loosening, thereby ensuring the safe and stable conveying of materials, improving work efficiency and reducing failures.

[0012] 2. The guide rail plays a role in supporting the traveling of the second chain plate traveling wheel and the first chain plate traveling wheel, and supports both ends of the chain plate, ensuring the stable operation of the chain plate, reducing noise, and at the same time improving the load-bearing capacity of the chain plate.

[0013] 3. The structure of the present utility model is compact, the parts have strong versatility, and it is convenient for installation and maintenance, and can meet the requirements of various complex working environments. The upper reinforcing plate and the lower reinforcing plate further strengthen the chain plate, preventing deformation.
