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 shuttle conveyor link type retractable ground cleaning device. 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 under the shuttle conveyor. During this process, the materials swept by the belt cleaner and the materials scattered from the belt will inevitably fall on the ground under the shuttle conveyor. Therefore, it is necessary to design a cleaning device under the shuttle conveyor to complete this work.

[0003] The traditional shuttle car ground cleaning device uses a sector gear, ratchet, pawl, crank and other devices to control the lowering of the scraper for scraping when moving forward and the raising of the scraper to avoid scraping backward when moving backward. However, this method has defects such as complex structure, high processing and manufacturing precision requirements, 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 shuttle conveyor link type retractable ground cleaning device with simple structure, easy processing and manufacturing, and convenient installation.

[0008] The scraper assembly includes a scraper bracket and side columns, a scraper provided on the scraper bracket, a square hole is opened at the upper end of the side columns, and the scraper assembly is located between the two bottom beams of the shuttle conveyor.

[0009] The rocker arm includes a connecting rod I and a rigid shaft. One end of this rigid shaft is a round shaft rigidly connected to one end of the connecting rod I, and the other end is a square cross-section. A shaft hole is opened on the web of the I-shaped bottom beam of the shuttle conveyor. The rigid shaft passes through the sleeve I and then through this shaft hole, and then through the sleeve II, and finally the other end with a square cross-section is connected to the square hole on the side column of the scraper assembly. The rocker arm and the scraper assembly form a rigid assembly, and the rocker arm is placed outside the two bottom beams.

[0010] The other end of the rocker arm link Ⅰ is hinged to one end of the link Ⅱ, the other end of the link Ⅱ is hinged to one end of the link Ⅲ, and a roller Ⅰ is clamped between these hinge points. The other end of the link Ⅲ is hinged to a shaft hole on the web of the I-shaped bottom beam of the shuttle-type spreader through a pin shaft, and a sleeve Ⅲ is clamped between the link Ⅲ and the bottom beam web.

[0011] The slideway groove is arranged on the bottom plate of the I-shaped bottom beam of the shuttle-type spreader, and the sliding trolley is placed inside the slideway groove.

[0012] The sliding trolley includes a trolley frame, an adjusting rod and a roller Ⅱ arranged on the trolley frame, and a groove is provided on the upper part of the trolley frame.

[0013] The lever is fixed on the ground at the front and rear ends of the moving range of the shuttle-type spreader and is used to assist in the retraction and extension of the scraper assembly.

The rocker arm 2 and the scraper assembly 1 form a rigid assembly. The rocker arm 2 is placed outside the two bottom beams.

[0030] The other end of the link I 2.1 of the rocker arm 2 is hinged to one end of the link II 5. The other end of the link II 5 is hinged to one end of the link III 6, and a roller I 8 is clamped between these hinge points. The other end of the link III 6 is hinged to the shaft hole on the web of the I - shaped bottom beam of the shuttle - type cloth distributor through a pin shaft, and a sleeve III 7 is clamped between the link III 6 and the bottom beam web.

[0031] The slideway groove 10 is arranged on the bottom plate of the I - shaped bottom beam of the shuttle - type cloth distributor. The sliding trolley 9 is placed inside the slideway groove 10.

[0032] The sliding trolley 9 includes a trolley frame 9.2, an adjusting rod 9.1 and a roller II 9.3 arranged on this trolley frame 9.2. A groove is provided on the upper part of the trolley frame 9.2.

[0033] The described lever 11 is fixed on the ground at the front and rear ends of the moving range of the shuttle-type cloth distributor, and is used to assist in the retraction and extension of the scraper assembly 1.

[0034] For the link-type retraction and extension ground cleaning device of the shuttle-type cloth distributor of the present invention, the scraper assembly 1 is composed of a scraper support 1.1, a scraper 1.2 and a side column 1.3. A square hole is opened at the upper end of the side column 1.3. The rocker arm 2 is composed of a link Ⅰ 2.1 and a rigid shaft 2.2. One end of the rigid shaft 2.2 is a round shaft rigidly connected to one end of the link Ⅰ 2.1, and the other end is a square cross-section. A shaft hole is opened on the web of the I-shaped bottom beam of the shuttle-type cloth distributor. The rigid shaft 2.2 passes through the sleeve Ⅰ 3 and then through this shaft hole, and then through the sleeve Ⅱ 4. Finally, the other end with a square cross-section is connected to the square hole on the side column 1.3 of the scraper assembly 1. The rocker arm 2 and the scraper assembly 1 form a rigid assembly body, without relative displacement and rotation, realizing synchronous rotation, and are hung on the bottom beam of the shuttle-type cloth distributor. The scraper assembly 1 is located in front of the two bottom beams of the shuttle-type cloth distributor, and the rocker arm 2 is placed outside the two bottom beams. The other end of the link Ⅰ 2.1 of the rocker arm 2 is hinged to one end of the link Ⅱ 5. The other end of the link Ⅱ 5 is hinged to one end of the link Ⅲ 6, and a roller Ⅰ 8 is clamped between the hinge points. The other end of the link Ⅲ 6 is hinged to the shaft hole on the web of the I-shaped bottom beam of the shuttle-type cloth distributor through a pin shaft, and a sleeve Ⅲ 7 is clamped between the link Ⅲ 6 and the bottom beam web. A slideway groove 10 is installed on the bottom plate of the I-shaped bottom beam of the shuttle-type cloth distributor. The sliding trolley 9 is placed inside the slideway groove 10 and can slide freely in the groove. The sliding trolley 9 is composed of an adjusting rod 9.1, a trolley frame 9.2 and a roller Ⅱ 9.3. A groove is provided on the upper part of the trolley frame 9.2. The lever is fixed on the ground at the front and rear ends of the moving range of the shuttle-type cloth distributor, respectively used to assist in the retraction and extension of the scraper assembly 1.

[0035] The working principle of the link-type retraction and extension ground cleaning device of the shuttle-type cloth distributor of the present invention is:

[0036] As Figure 10As shown, when the shuttle material distributing machine moves forward, the scraper assembly 1 is in a vertical state. In the initial state, the sliding trolley 9 is at the front end of the slideway groove 10 and is supported against the roller Ⅰ8. The connecting rod Ⅱ5 and the connecting rod Ⅲ6 cannot rotate counterclockwise, so the scraper assembly 1 cannot rotate clockwise, so the bulk material is pushed to the front trough along the moving direction without rotating backward. When the shuttle material distributing machine is about to run to the front end limit position, the front end lever 11 shifts the adjustment rod 9.1 to make the sliding trolley 9 move backward in the slideway groove 10. The sliding trolley 9 pushes the roller Ⅰ8 to drive the connecting rod Ⅱ5 and the connecting rod Ⅲ6 to rotate clockwise. The scraper assembly 1 rotates counterclockwise and is gradually lifted up until the roller Ⅰ8 moves to the upper groove of the sliding trolley 9. The shuttle material distributing machine can retreat. At this time, the connecting rod Ⅱ5 and the connecting rod Ⅲ6 cannot rotate counterclockwise. Thereby, the clockwise rotation of the scraper assembly 1 is restricted, so that the shuttle conveyor retreats without scraping materials backwards after the scraper assembly 1 is retracted. When the shuttle conveyor is about to run to the rear end limit position, the rear end lever 11 moves the adjustment lever 9.1 to make the sliding trolley 9 move forward in the slideway groove 10. When the roller Ⅰ8 falls from the sliding trolley 9, the connecting rod Ⅱ5 and the connecting rod Ⅲ6 rotate counterclockwise, and the scraper assembly 1 rotates clockwise and is lowered until the sliding trolley 9 slides to the front end of the slideway groove 10 and is pressed against the roller Ⅰ8. The shuttle conveyor can then run forward and the scraper scrapes materials at the same time.

[0037] The shuttle-type material distributing machine connecting rod type retractable floor cleaning device of the present invention adopts a new form to realize that when the shuttle-type material distributing machine moves forward, the scraper 1.2 is lowered to the working state to scrape materials forward, and when the shuttle-type material distributing machine moves backward, the scraper 1.2 is lifted and recovered. This form has a simple structure, is easy to process and manufacture, and is convenient to install, and overcomes the defects of traditional fan-shaped gear, ratchet and pawl type floor cleaning devices such as complex structure, high processing and manufacturing precision requirements, difficult installation, and easy damage in harsh working environments.
