Abstract
The utility model provides an improved sweeper knife rest, includes seamless steel pipe and two channel-section steels, two channel-section steels all have a U type section separately, two the parallel interval of channel-section steel set up and the symmetry sets up the outside of seamless steel pipe, seamless steel pipe set up the recess of two channel-section steels between, the both wings of channel-section steel respectively with seamless steel pipe's outer wall welding, the bottom surface outside of one of them channel-section steel is provided with two scraper fixed plates perpendicularly, two scraper fixed plate parallel arrangement, be provided with a scraper between two scraper fixed plates. The utility model discloses a two channel-section steels replace square pipe, match the pipe specification more easily, and the scraper passes through scraper fixed plate, channel-section steel and seamless steel pipe fixed connection, and the sweeper knife rest is that the monolithic connection is made, has improved intensity, adopts bolt and lock nut fixed between scraper and the knife rest, makes the structure more firm.
Description
Technical Field
The utility model relates to the field of machinary, especially, relate to cleaning device, be a modified sweeper knife rest particularly.
Background
In the prior art, a sweeper knife rest on a coal mine conveying belt is composed of a round pipe and a square pipe, the round pipe is arranged in the square pipe, the steel pipe is welded with the square pipe, the closest distance between the inner wall of the square pipe and the outer surface of the steel pipe is less than or equal to 1.5mm, and a scraper is fixed with the knife rest through a pin shaft. The following problems mainly exist in the manufacture of the tool holder: (1) in order to improve the strength of the tool rest, the designed square tube has a certain wall thickness, because the nearest distance between the inner wall of the square tube and the outer surface of the steel tube is less than or equal to 1.5mm, the steel tube is easier to purchase under the condition that the outer diameter of the steel tube and the outer diameter of the square tube are determined, the yield of the square tube with the specification is possibly low, the purchase is very difficult, if the drawing of the tool rest is redesigned, the outer diameter of the steel tube and the wall thickness of the square tube need to be modified, and the. (2) The scraper and the knife rest are fixed by a pin shaft, and the structure is not firm.
SUMMERY OF THE UTILITY MODEL
The utility model provides a modified sweeper knife rest, this kind of modified sweeper knife rest solve among the prior art sweeper knife rest because square pipe specification can not match the intensity that leads to inadequately and the insecure technical problem of scraper with the specification of pipe.
The utility model discloses a modified sweeper knife rest, including seamless steel pipe and two channel-section steels, two channel-section steels all have a U type section separately, two the parallel interval of channel-section steel set up and the symmetry sets up seamless steel pipe's the outside, seamless steel pipe set up the recess of two channel-section steels between, the both wings of channel-section steel respectively with seamless steel pipe's outer wall welding, the bottom surface outside of one of them channel-section steel is provided with two scraper fixed plates perpendicularly, two scraper fixed plate parallel arrangement, be provided with a scraper between two scraper fixed plates.
Furthermore, the side walls of the two ends of the seamless steel pipe are respectively provided with at least one through hole, and the through holes penetrate through the seamless steel pipe.
Furthermore, the scraper fixing plates are provided with round holes, the scraper is fixed between the two scraper fixing plates through bolts and locking nuts, and the bolts are arranged in the round holes.
The utility model discloses a theory of operation: at first the utility model discloses an improved sweeper knife rest is installed on conveyer aircraft nose cylinder frame, again to the scraper laminating on the improved sweeper knife rest on conveyer aircraft nose cylinder, then the scraper cleans the material on the conveyer belt along the movement track of conveyer aircraft nose cylinder, and the material that cleans all falls into the feed bin.
The utility model discloses a two channel-section steels replace square pipe, match the pipe specification more easily, and the scraper passes through scraper fixed plate, channel-section steel and seamless steel pipe fixed connection, and the sweeper knife rest is that the monolithic connection is made, has improved intensity, adopts bolt and lock nut fixed between scraper and the knife rest, makes the structure more firm.

Detailed Description
Example 1:
as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model provides an improved sweeper knife rest, including seamless steel pipe 2 and two channel-section steels 3, two channel-section steels 3 all have a U type section separately, two the parallel interval of channel-section steel 3 set up and the symmetry sets up seamless steel pipe 2's the outside, seamless steel pipe 2 set up two channel-section steels 3's between the recess, channel-section steel 3's both wings respectively with seamless steel pipe 2's outer wall welding, one of them channel-section steel 3's the bottom surface outside is provided with two scraper fixed plates 4 perpendicularly, two scraper fixed plates 4 parallel arrangement, be provided with a scraper 6 between two scraper fixed plates 4.
Furthermore, the side walls of the two ends of the seamless steel tube 2 are respectively provided with at least one through hole 1, and the through holes 1 penetrate through the seamless steel tube 2.
Further, the scraper fixing plates 4 are provided with round holes 5, the scraper 6 is fixed between the two scraper fixing plates 4 through bolts and locking nuts, and the bolts are arranged in the round holes 5.
The working principle of the embodiment is as follows: at first the utility model discloses an improved sweeper knife rest 9 installs on conveyer aircraft nose cylinder frame 10, laminates 6 scraper on the improved sweeper knife rest 9 on conveyer aircraft nose cylinder 8 again, then scraper 6 cleans the material on conveyer belt 7 along the movement track of conveyer aircraft nose cylinder 8, and the material that cleans all falls into the feed bin.
