Description

Technical Field

[0001] The invention belongs to the technical field of mining machinery, and in particular relates to a falling material collecting device for a heavy-duty plate feeder. Background Art

[0002] Heavy-duty apron feeder is a continuous conveying machine widely used in mining, metallurgy and other industries. It is mainly used to continuously and evenly supply and transfer various bulk materials from storage bins or transfer hoppers to crushers, batching devices or transportation equipment. It is one of the indispensable equipment in ore processing and continuous production. It includes components such as drive system, chain belt system, spindle system, support system and tensioning system. It has the advantages of large feeding capacity, large feed particle size, ability to withstand certain large-block material impact, ability to transport hot materials, tiltable layout and low noise.

[0003] In the chain-belt system of a heavy-duty apron feeder, the chain is driven by a sprocket, which in turn drives the chain plates in continuous motion. The chain plates are connected to the chain by bolts. Due to gaps between adjacent chain plates at the joint, material shedding is common at the joint. Due to the limited space in the chain-belt system, the current method of manually cleaning the material shedding is time-consuming and difficult to clean, increasing the operating cost of the heavy-duty apron feeder. If material spills in the chain-belt system and is not promptly cleaned, it increases the operating power of the heavy-duty apron feeder, reducing operating efficiency. The accumulation of material shedding can even cause the chain-belt system to jam, potentially damaging the equipment. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a heavy-duty plate feeder drop collection device to promptly remove droplets at the joint of the chain plates and improve the working efficiency of the heavy-duty plate feeder.

[0005] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0006] A heavy-duty apron feeder drop collection device includes a special-shaped aggregate trough, a trough bracket, a water spray device, and a material collection box. The trough bracket includes an inclined bracket and a hanging bracket. The water spray device includes a transverse nozzle, a chute nozzle, a transverse pipe, and a chute pipe. The special-shaped aggregate trough is mounted on the tensioning pulley shaft at the rear of the heavy-duty apron feeder via the trough bracket. The trough bracket is welded to the tensioning pulley shaft, and the special-shaped aggregate trough is welded to the trough bracket. The water spray device is installed inside the special-shaped aggregate trough. The transverse nozzles are installed on the transverse pipes at equal intervals through threaded connections. The chute nozzles are installed on the chute pipes at equal intervals through threaded connections. The transverse pipes and chute pipes are welded to the special-shaped aggregate trough and both are supplied with high-pressure water by a water pump. The material collection box is placed at the discharge end of the special-shaped aggregate trough. The material falls from the joint of the chain plates and falls into the storage box on the back of the lower chain plate. When the chain plate runs to the tail of the heavy-duty plate feeder and turns, the material falls from the storage box to the special-shaped aggregate trough by gravity. The water spray device regularly flushes the material in the special-shaped aggregate trough into the receiving box.

[0007] Preferably, the special-shaped aggregate trough is welded on the aggregate trough bracket at a certain tilted angle. Along the cross-sectional direction of the tensioning wheel shaft, one end of the special-shaped aggregate trough close to the tail of the heavy-duty plate feeder is higher than the other end away from the tail of the heavy-duty plate feeder. Along the axial direction of the tensioning wheel shaft, one end of the special-shaped aggregate trough is higher than the discharge port at the other end, so that the special-shaped aggregate trough is arranged in a three-dimensional tilted manner, which is convenient for collecting fallen materials.

[0008] Preferably, the inclined bracket and the suspension bracket are formed by bending angle steel, and the middle part of the aggregate trough bracket is welded to the tensioning wheel shaft, wherein the two ends of the inclined bracket are welded to the end of the special-shaped aggregate trough, and the two ends of the suspension bracket are welded to the inner surface of the special-shaped aggregate trough.

[0009] Preferably, the inclined brackets and the suspension brackets are alternately arranged along the tensioning wheel shaft, and the number of the inclined brackets is at least 4.

[0010] Preferably, the chute nozzle regularly sprays high-pressure water to flush the fallen materials accumulated on the upper part of the aggregate trough to the low-lying part of the aggregate trough, and the transverse nozzle regularly sprays high-pressure water to flush the fallen materials in the low-lying part of the aggregate trough into the material receiving box, and the chute nozzle and the transverse nozzle do not spray high-pressure water at the same time.

[0011] Preferably, the nozzle direction of the longitudinal nozzle is perpendicular to the axial direction of the tensioning wheel shaft, and the nozzle direction of the transverse nozzle forms an acute angle with the axial direction of the tensioning wheel shaft and is biased toward the low-lying part of the special-shaped aggregate trough, so that the transverse nozzle can flush the falling material into the material receiving box.

[0012] The beneficial effects of the present invention are:

[0013] 1. The present invention collects the falling materials through the special-shaped collecting trough and uses the water spray device to flush the falling materials to the receiving box, which can timely remove the falling materials in the chain belt system and improve the working efficiency of the heavy-duty plate feeder.

[0014] 2. The special-shaped aggregate trough is directly welded to the tension wheel shaft at the tail of the heavy-duty apron feeder through the aggregate trough bracket, which solves the problem of material falling without changing the existing structure of the heavy-duty apron feeder and has a wide range of applications.

[0015] 3. Use high-pressure water spray to flush the falling materials regularly to prevent dust pollution generated during the collection process of falling materials from heavy-duty plate feeders. BRIEF DESCRIPTION OF THE DRAWINGS
