Volgograd Specialized Design and Technological Bureau of Mechanization and Automation of Transport and Warehousing of the Scientific Production Association ’’ Complex ’(54) DEVICE FOR CLEANING OPENINGS OF A CHANGE CONVEYOR

The conveyor belongs to the conveying equipment and can be used at machine-building enterprises for the transportation of metal chips with cutting fluid coolant, with the separation of coolant from the chips during transportation. ⁵ Known chip conveyors containing a stationary trough along which the working body moves the chips. In the bottom of the gutter, holes were made for draining the coolant, which moves along the conveyor along with the chips (1].

The disadvantage of these conveyors is that they do not have devices for cleaning the coolant drain holes. As a result, these holes are clogged with coolant and fine chips and must be periodically manually cleaned, which reduces conveyor performance.

A device for separating zhidkoe- _m tee comprising a trough along which the working fluid (water) to move the rock. Holes are made in the bottom of the gutter to separate part of the rock. To clean this hole, a device made in the form of a swinging lever provided by the movement of the working fluid through the turbine and the mechanism for converting the rotational motion of the turbine into the swinging motion of the lever [2J.

The described device for cleaning the hole can be used in a chip conveyor having holes in the trench for draining the coolant.

The disadvantage of this conveyor is the complexity of the named device due to the presence of a mechanism for converting the translational movement of the working body into a swinging movement of the lever. This is compounded by the fact that the conveyor should have not one, but many holes for draining the coolant and, accordingly, many devices for cleaning them.

The aim of the invention is to simplify the design of the conveyor by simplifying the design of the device for cleaning holes.

To achieve this goal, the cleaning element is made in the form of a wheel with blades, installed with the possibility of inter

yep. The blades can be made C-shaped. }

In FIG. 1 is a longitudinal section of a scraper conveyor; in FIG. 2 - section AA 5 of FIG. 1; ny FIG. 3 is a view B of FIG. 1; in FIG. 4, section BB of FIG. 2.

On the frame 1, the grooved sections 2 are fixed, which make up the working cavity of the conveyor, as well as the endless traction chains 3, on which ¹⁰ scrapers 4 are mounted, moving along the groove 2. One or more of the grooved sections 2 are dividing, because they are separated coolant from the chips. fifteen

The dividing section 5 is made in the form of a frame frame 6, in the bottom of which there are openings 7 for draining the coolant, in each of which cleaning elements are installed.

The cleaning element is made in the form of a 20-forest 8, consisting of blades 9 radially mounted on a shaft 10 rotating in bearings.

The device operates as follows.

Metal chips with coolant scrapers 25 move along the groove sections 2. When they enter the separation section 5, coolant is drained through openings 7 into special collectors 11, and the chip continues to be transported along the conveyor. thirty

Each scraper 4, when moving, acts on one of the blades 9 of the wheel 8, which at this moment protrudes above the bottom of the trough 2, while the wheel 8 rotates, cleaning the hole 7. In order for the blades 9 to "spread" the chip, pushing it into the hole 7, they are made C-shaped, with a bulge in the direction of rotation. The blades should be at least 4, then when one of them enters the hole 7, the next blade will protrude from the last (behind the scraper).

The coolant separator can also be used in a screw chip conveyor.

Claims (2)

1 The conveyor relates to transport equipment and can be used in engineering enterprises for transporting metal chips with coolant, with the coolant removed from the chip during transport. Known chip conveyors containing a fixed chute, along which the working body moves the chips. In the bottom of the chute, there are holes for coolant that travels along the conveyor along with chips 11. The sufficiency of these conveyors is that there are no devices for cleaning the coolant holes. As a result, this hole is loose & coolant and fine shavings and must be cleaned manually from time to time, which reduces the conveyor's performance. A device for separating a liquid is known, comprising a chute along which the working fluid (water) moves the rock. Holes are made in the bottom of the gutter to separate part of the rock. To clean this hole, a device is provided, implemented in the form of a swinging lever, driven by the movement of the working fluid through the turbine and a mechanism for converting the turbine rotational motion into a swinging motion of the grunt 2. The opening hole cleaning device can also be used in the chip harvesting conveyor with an opening in the chute to drain coolant. The disadvantage of such a conveyor is the complexity of said device due to the presence of a mechanism for converting the translational movement of the working member into the oscillating movement of the lever. This is aggravated by the fact that the conveyor must have not one, but many holes for coolant and, accordingly, many devices for their cleaning. The aim of the invention is to simplify the design of the conveyor by simplifying the design of the device for cleaning the hole. Achieve the goal, the cleaning element is made in the form of a wheel with blades installed with the ability of the blades to interact with the working body of the conveyor. The blades can be made C-shaped. FIG. 1 is a longitudinal section of a scraper conveyor; in fig. 2 is a section A-A of FIG. one; n FIG. 3 - view B of FIG. one; in fig. 4 section bb FIG. 2. On the frame 1, the grooved sections 2 are fixed, constituting the working cavity of the conveyor, as well as the endless pulling chains 3 on which the scrapers 4 are fixed, moving along the groove 2. One or more of the grooved sections 2 are separable, since coolant is separated from chips. The separating section 5 is made in the form of a frame frame 6, in the bottom of which there are openings 7 for draining the coolant, each of which has cleaning elements. The cleaning element is made in the form of a wheel 8, consisting of blades 9, radially mounted on an iO shaft, rotating in under the tongs. The device works as follows. The metal chips together with the coolant scraps 4 are moved along the grooved sections. When they hit the separator section 5, coolant flows through the holes 7 into special collectors 11, and CTpjoKKa continues to transport through the conveyor. Each scraper 4, when moving, acts on one of the blades 9 of the wheel 8, which at this moment extends above the bottom of the groove 2, while the wheel 8 rotates, cleaning the hole 7. In order for the blades 9 to move the chips apart, not pushing it into the hole 7, they are C-shaped, with a bulge in the direction of rotation. The blades must be at least 4, then when one of them enters the hole 7, the next blade will come out of the last (behind the scraper). A coolant separator can also be used in a screw-dispensing conveyor. Claim 1. Device for cleaning holes of cTpyajc harvesting conveyor, including cleaning element mounted on an axis in the opening of the conveyor chute rotatably under the action of the conveyor operating element, it is conclusive that, in order to simplify the design, cleaning the sensor is done in the form of a wheel with blades installed with the possibility of interaction of the blades with the working body of the conveyor. 2. The device according to claim 1, wherein the blades are made C-shaped with a bulge in the direction of rotation. Sources of information that are taken into account in the examination of 1.Frost B.N.
