Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a scraper conveyor plug-in plate opening and closing device. Background Art

[0002] The blade of a scraper conveyor is a plate used to control materials and cleaning media. The disadvantage of the layout of the middle slot of the scraper conveyor is that the blade is too large in the push-pull direction, which occupies a large space and is not conducive to the use of limited space in coal mines. For this reason, Chinese patent CN112520319A proposes a device for opening and closing the blade of a filling scraper conveyor discharge port. The device saves operating space by setting two sets of gear rack mechanisms and two reciprocating telescopic mechanisms, but the design structure is relatively complex, and the gear rack mechanism is more worn during use. Utility Model Content

[0003] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a scraper conveyor blade opening and closing device.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A scraper conveyor plate opening and closing device comprises a middle groove and a plate, wherein the middle groove is provided with an opening, and the plate is slidably arranged at the opening; it also comprises an oil cylinder hingedly arranged on the side of the middle groove and a horizontally arranged guide rod, wherein the oil cylinder is hingedly connected to a slide seat slidably arranged on the guide rod, and a connecting rod is hingedly connected to the slide seat, and the end of the connecting rod is hingedly connected to the plate, and the operation of the oil cylinder causes the slide seat to move linearly along the guide rod, so that the connecting rod pushes the plate forward or backward.

[0006] Furthermore, the oil cylinder is hinged to the side of the middle groove through a first hinge block.

[0007] Furthermore, the oil cylinder is hinged to one side of the slide seat through a second hinge block.

[0008] Furthermore, the connecting rod is hinged to the plug plate through a third hinge block.

[0009] Furthermore, the third hinge block is located at the bottom of the plugboard.

[0010] Furthermore, the guide rod is located below the plug board to improve the aesthetics of the structure.

[0011] Furthermore, when the plug plate is in a closed state, the connecting rod is tilted, and the lowest end of the connecting rod is connected to the second hinge block, and the highest end of the connecting rod is connected to the third hinge block so that the connecting rod can perform an upward movement under the action of the oil cylinder.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model has a simple structure. The operation of the oil cylinder causes the slide seat to move linearly along the guide rod, and finally the connecting rod pushes the plug plate forward or backward to open or close the opening. The device uses fewer parts, has good wear resistance, is easy to maintain, and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0020] Refer to the attached Figure 1 -Attached Figure 4 As shown, a scraper conveyor plate opening and closing device includes a middle groove 1 and a plate 12. The middle groove 1 is provided with an opening 11, and the plate 12 is slidably arranged at the opening 11; it also includes a cylinder 3 hingedly arranged on the side of the middle groove 1 and a horizontally arranged guide rod 4, the cylinder 3 is hinged to a slide 5 slidably arranged on the guide rod 4, and a connecting rod 7 is hinged on the slide 5, and the end of the connecting rod 7 is hinged to the plate 12. The operation of the cylinder 3 causes the slide 5 to move linearly along the guide rod 4, so that the connecting rod 7 pushes the plate 12 forward or backward.

[0021] Specifically, the oil cylinder 3 is hinged to the side of the middle slot 1 through the first hinge block 2 .

[0022] Specifically, the oil cylinder 3 is hinged to one side of the slide seat 5 through the second hinge block 6 .

[0023] Specifically, the connecting rod 7 is hinged to the bottom of the inserting plate 12 through the third hinge block 8 .

[0024] Specifically, the guide rod 4 is located below the inserting plate 12 to improve the aesthetics of the structure.

[0025] When the plug plate 12 is in a closed state, the connecting rod 7 is tilted, and the lowest end of the connecting rod 7 is connected to the second hinge block 6, and the highest end of the connecting rod 7 is connected to the third hinge block 8 so that the connecting rod 7 can perform an upward movement under the action of the oil cylinder 3.

[0026] The device has a simple structure. In the specific implementation process, the oil cylinder 3 operates to make the slide 5 move linearly along the guide rod 4, and finally the connecting rod 7 pushes the plug plate 12 forward or backward to open or close the opening 11.
