Description

Technical Field

[0001] The invention belongs to the technical field of shuttle conveyors in the feeding process of the sintering process in the metallurgical industry, and particularly relates to a rotary lifting type ground cleaning device for a shuttle conveyor with retractable and extendable functions. Background Art

[0002] The shuttle conveyor is applicable to the feeding operation in the sintering process. After the materials are mixed, they are conveyed to the conveyor belt of the shuttle conveyor and fall into the trough through the belt. The shuttle conveyor is provided with a traveling mechanism that can reciprocate, so that the sintered mixed materials can be evenly distributed in the trough below the shuttle conveyor. During this process, the materials swept by the belt cleaner and the materials scattered from the belt will inevitably fall onto the ground below the shuttle conveyor. Therefore, it is necessary to design a cleaning device under the shuttle conveyor to complete this work.

[0003] The traditional ground cleaning device of the shuttle conveyor uses devices such as sector gears, ratchets, pawls, and cranks to control the lowering of the scraper for scraping materials during forward movement and the lifting of the scraper to avoid backward scraping during backward movement. However, this method has defects such as complex structure, high requirements for machining accuracy, difficult installation, and easy damage in harsh working environments.

[0004] Therefore, a new method is needed to improve this situation. Summary of the Invention

[0005] The purpose of the invention is to overcome the defects existing in the prior art and provide a rotary lifting type ground cleaning device for a shuttle conveyor with a simple structure, easy machining and manufacturing, and convenient installation.

[0006] The purpose of the invention is achieved by the following technical solutions:

[0007] The rotary lifting type ground cleaning device for a shuttle conveyor of the invention is characterized by comprising jacking tracks fixed on the ground at the front and rear ends of the moving range of the shuttle conveyor, and two sets of upper supports, lower supports, rotary supports, ejector rods and scraper assemblies symmetrically arranged and installed under the double-side bottom beams of the shuttle conveyor.

[0008] The upper support is fixed under the bottom beam of the shuttle conveyor through a bolt group. The upper support consists of an upper base and an upper tooth plate. The upper tooth plate is a downward-facing cylindrical tooth shape. The lower support is connected to the upper support through a bolt group and a steel pipe.

[0009] The lower support consists of a lower base and a lower tooth plate. The lower tooth plate is an upward-facing cylindrical tooth shape. The steel pipe is sleeved on the bolt and clamped between the upper base and the lower base, so that a circumferential tooth-shaped slideway is formed between the upper tooth plate and the lower tooth plate.

[0010] The arc top sliding base of the described rotary support is placed between the upper tooth plate and the lower tooth plate, and the sliding lifting lug of the rotary support is placed in the circumferential tooth-shaped slideway formed between the upper tooth plate and the lower tooth plate.

[0011] The described ejector rod includes an arc top, a roller bracket, rollers and a pin shaft. The arc top is placed between the arc top sliding base and the lower base, enabling the ejector rod to be freely suspended.

[0012] The circumferential tooth-shaped slideway formed between the upper tooth plate and the lower tooth plate has a pair of high parking positions and a pair of low parking positions, and the high and low positions are alternately distributed at a 90-degree angle.

[0013] The tooth valleys of the upper tooth plate and the tooth peaks of the lower tooth plate, and the tooth peaks of the upper tooth plate and the tooth valleys of the lower tooth plate are vertically offset.

[0014] The described scraper assembly includes a scraper bracket, a scraper, a sliding support rod and an arc bottom sliding base. The arc bottom sliding base is placed in the "C"-shaped box groove of the upper support and rests on the arc top sliding base.

[0015] When the roller is subjected to the thrust of the lifting track, the ejector rod will rotate and lift the rotary support.

[0016] Advantages of the present invention:

[0017] The rotary lifting type ground cleaning device for the shuttle type spreader of the present invention realizes that when the shuttle type spreader moves forward, the scraper is lowered to the working state to scrape the material forward, and when the shuttle type spreader moves backward, the scraper is lifted and recovered. This form has a simple structure, is easy to process and manufacture, and is convenient to install, overcoming the defects of the traditional ground cleaning device in the form of a sector gear, ratchet and pawl, such as complex structure, high precision requirements for processing and manufacturing, difficult installation, and easy damage in a harsh working environment.

[0039] The circumferential tooth-shaped slideway formed between the upper tooth plate 1.2 and the lower tooth plate 5.2 has a pair of high parking positions and a pair of low parking positions, and the high and low positions are alternately distributed at a 90-degree angle.

[0040] The tooth valleys of the upper tooth plate 1.2 and the tooth peaks of the lower tooth plate 5.2, and the tooth peaks of the upper tooth plate 1.2 and the tooth valleys of the lower tooth plate 5.2 are vertically offset.

[0041] The scraper assembly 7 includes a scraper bracket 7.1, a scraper 7.2, a sliding support rod 7.3 and an arc bottom sliding base 7.4. The arc bottom sliding base 7.4 is placed in the "C"-shaped box groove of the upper support 1 and rests on the arc top sliding base 4.1.

[0042] The rotary lifting type ground cleaning device for the shuttle cloth distributing machine of the present invention, the upper support 1 is fixed below the bottom beam of the shuttle cloth distributing machine through the bolt group 2. The upper support 1 is composed of an upper base 1.1 and an upper tooth plate 1.2. The upper tooth plate 1.2 is cylindrical with the teeth facing downwards; the lower support 5 is connected to the upper support 1 through the bolt group 2 and the steel pipe 3. The lower support 5 is composed of a lower base 5.1 and a lower tooth plate 5.2. The lower tooth plate 5.2 is cylindrical with the teeth facing upwards; the steel pipe 3 is sleeved on the bolt and clamped between the upper base 1.1 and the lower base 5.1, so that a circumferential tooth-shaped slideway is formed between the upper tooth plate 1.2 and the lower tooth plate 5.2. A pair of high parking positions and a pair of low parking positions are formed between the upper tooth plate 1.2 and the lower tooth plate 5.2, and the high and low positions are alternately distributed at a 90-degree angle; the arc top sliding base 4.1 of the rotary support 4 is placed in the circumferential tooth-shaped slideway formed between the upper tooth plate 1.2 and the lower tooth plate 5.2, and the sliding lug 4.2 is placed in the circumferential tooth-shaped slideway formed between the upper tooth plate 1.2 and the lower tooth plate 5.2; the tooth valleys of the upper tooth plate 1.2 and the tooth peaks of the lower tooth plate 5.2, and the tooth peaks of the upper tooth plate 1.2 and the tooth valleys of the lower tooth plate 5.2 are vertically offset, which plays a guiding role when the sliding lug 4.2 slides to the turning point, so that the entire rotary support 4 can rotate unidirectionally and alternately park at the high and low positions; the top rod 6 is composed of a roller bracket 6.2, a roller 6.3 and a pin shaft 6.4.

[0043] The working principle of the rotary lifting type ground cleaning device for the shuttle cloth distributing machine of the present invention is as follows:

[0044] Such as Figure 15As shown, the jacking tracks 8 are fixed on the ground at the front and rear ends of the moving range of the shuttle feeder, and are respectively used to assist in the retraction and extension of the scraper assembly 7. When the shuttle feeder moves forward, the scraper assembly 7 is parked at a low position along with the rotary support 4, and the bulk material is pushed forward into the front chute along the moving direction. When the shuttle feeder runs to the front limit position, when the roller 6.3 receives the thrust of the front jacking track 8, the ejector rod 6 rotates and lifts the rotary support 4, driving the scraper assembly 7 to rise together. After the sliding lug 4.2 jumps over the tooth edge of the lower toothed plate 5.2, the shuttle feeder can retreat. The ejector rod 6 runs downhill along the jacking track 8, and under the action of gravity, the rotary support 4 and the scraper assembly 7 descend until they are parked at a high position, realizing that the shuttle feeder can retreat without scraping the material backward after the scraper assembly 7 is retracted. When the shuttle feeder runs to the rear limit position, when the roller 6.3 receives the thrust of the front jacking track 8, the ejector rod 6 rotates and lifts the rotary support 4, driving the scraper assembly 7 to rise together. After the sliding lug 4.2 jumps over the tooth edge of the lower toothed plate 5.2, the shuttle feeder can move forward. The ejector rod 6 runs downhill along the jacking track 8, and under the action of gravity, the rotary support 4 and the scraper assembly 7 descend until they are parked at a low position, and the shuttle feeder can move forward while the scraper 7.2 scrapes the material.

[0045] The rotary lifting type retractable ground cleaning device of the shuttle feeder of the present invention realizes the lowering of the scraper 7.2 to the working state to scrape the material forward when the shuttle feeder moves forward and the lifting and recycling of the scraper 7.2 when the shuttle feeder retreats in a new form. This form has a simple structure, is easy to process and manufacture, and is convenient to install, overcoming the defects of the traditional ground cleaning devices in the form of sector gears, ratchets and pawls, such as complex structure, high precision requirements for processing and manufacturing, difficult installation, and easy damage in harsh working environments.
