Description

Technical Field

[0001] The utility model relates to the technical field of material guide troughs, in particular to a dust reduction material guide trough skirt plate sealing structure. Background Art

[0002] The guide chute is an auxiliary device installed on the belt conveyor to prevent the material from scattering outwards during the material transfer process. In order to prevent dust, skirt sealing structures are installed on both sides of the guide chute. The skirt sealing structure of the prior art is generally as shown in the patent application number 202120489192.2 entitled A Coal Conveyor Belt Guide Chute Sealing Structure. Figure 3 As shown, it includes an L-shaped pressing plate (one end of which is provided with a supporting plate), the head of the pressing handle is rotatably connected to a pulling rod, which passes through the middle of the pressing plate and is connected to a base fixed to the side wall of the trough body. The head of the pressing handle is an eccentric structure. By rotating the pressing handle, the end of the pressing plate away from the supporting plate can be pressed against the angle aluminum, thereby pressing the skirt plate against the side wall of the trough body. However, less than half of the force of the pressure of the pressing handle is applied to the angle aluminum and the skirt plate, and the rest of the force is borne by the supporting plate, resulting in a larger force required to rotate the pressing handle to press the skirt plate when the force arm of the pressing handle is the same. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a dust reduction material guide chute skirt plate sealing structure in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a dust reduction and material guide trough skirt sealing structure, including a trough body, a skirt plate is arranged on the outer side of the lower part of the side wall of the trough body, and also includes a plurality of clamps, the clamp includes a base arranged on the side wall of the trough body, the base is connected with a bolt, the bolt is threadedly connected with a pull block, a first rotating shaft is arranged on both sides of the pull block, a first through hole rotatably connected to the first rotating shaft is arranged on both sides of the middle part of the pressure arm, a second rotating shaft and a notch are respectively arranged on the upper and lower ends of the pressure arm, a second through hole rotatably connected to the second rotating shaft is arranged on the head of the pressure handle, the head of the pressure handle is an eccentric structure, and rotating the pressure handle can generate pressure between the head and the trough body, thereby pressing the round tube located in the notch to the outer side of the skirt plate, thereby pressing the skirt plate to the side wall of the trough body.

[0005] Curved portions are provided on both sides of the head of the pressure handle, and a plane portion is between the two curved portions. The distance between the curved portion and the second through hole gradually increases from an end away from the plane portion to an end close to the plane portion, and the distance between the end of the curved portion away from the plane portion and the second through hole is smaller than the distance between the plane portion and the second through hole, and the distance between the end of the curved portion close to the plane portion and the second through hole is larger than the distance between the plane portion and the second through hole.

[0006] The base is a C-shaped channel steel, and one end of the bolt is provided with a head which can be inserted into the base from one side.

[0007] The cross section of the notch is an isosceles trapezoid.

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0014] Specific implementation method: Combination Figure 1-3As shown, a dust reduction material guide trough skirt sealing structure includes a trough body 1, a skirt plate 2 is arranged on the outer side of the lower part of the side wall of the trough body 1, and the lower end of the skirt plate 2 is in contact with the upper surface of the conveyor belt 3, which can greatly reduce the amount of dust scattered from both sides of the conveyor belt 3 into the air, and also includes a plurality of clamps 5, which are used to press the skirt plate 2 against the side wall of the trough body 1, and the clamp 5 includes a base 51 arranged on the side wall of the trough body 1, and the base 51 can be welded to the trough body 1, and the base 51 is connected to a bolt 54, and the bolt 54 is threadedly connected to a pull block 55, and the pull block 55 is provided with a threaded hole for threaded connection with the bolt 54, and both sides of the pull block 55 A first rotating shaft 551 is provided, and first through holes rotatably connected to the first rotating shaft 551 are provided on both sides of the middle of the pressure arm 52. The rotation of the pressure arm 52 can drive the pull block 55 to rotate, and the distance between it and the base 51 can be adjusted according to actual conditions. The upper and lower ends of the pressure arm 52 are respectively provided with a second rotating shaft and a notch 521, and the head of the pressure handle 53 is provided with a second through hole 531 rotatably connected to the second rotating shaft. The head of the pressure handle 53 is an eccentric structure. Rotating the pressure handle 53 can generate pressure between the head and the tank body 1, thereby pressing the round tube 4 located in the notch 521 against the outer side of the skirt board 2, thereby pressing the skirt board 2 against the side wall of the tank body 1. Since the bolt 54 and the round tube 4 are respectively located at the two ends of the pressure arm 52, under the same other conditions, the force required to rotate the pressure handle 53 to press the skirt board 2 is smaller than that in the background technology, so it is more labor-saving. In addition, the angle aluminum has two sides to press the skirt board 2, and the width of the skirt board 2 occupied between the two sides is wider. After the round tube 4 is used to replace the angle aluminum, the contact part between the round tube 4 and the skirt board 2 is close to a line, and the width of the skirt board 2 occupied is narrower. Therefore, the width of the skirt board 2 can be made narrower, thereby saving materials.

[0015] Specifically, curved surface portions 532 are provided on both sides of the head of the pressure handle 53, and a plane portion 533 is provided between the two curved surface portions 532. The distance between the curved surface portion 532 and the second through hole 531 gradually increases from an end away from the plane portion 533 to an end close to the plane portion 533. The distance between the end of the curved surface portion 532 away from the plane portion 533 and the second through hole 531 is smaller than the distance between the plane portion 533 and the second through hole 531, and the distance between the end of the curved surface portion 532 close to the plane portion 533 and the second through hole 531 is larger than the distance between the plane portion 533 and the second through hole 531.

[0016] Preferably, the base 51 is a C-shaped channel steel, and one end of the bolt 54 is provided with a head that can be inserted into the base 51 from one side. When the old skirt board 2 is removed and replaced with a new one, if the notch 521 is deep, the part of the clamp 5 except the base 51 can be removed from one side of the base 51, and after the round tube 4 is placed in place, the notch 521 is attached to the round tube 4, and then the head of the bolt 54 is inserted into the base 51 from one side, and then the pressing handle 53 is turned to press the round tube 4 against the skirt board 2, thereby pressing the skirt board 2 against the side wall of the tank body 1. If the notch 521 is shallow, the part of the clamp 5 except the base 51 does not need to be removed from one side of the base 51.

[0017] Preferably, the cross section of the notch 521 is an isosceles trapezoid, which is half of a regular hexagon, and the outer circumference of the circular tube 4 is inscribed in the regular hexagon, so that after each compression, the position of the circular tube 4 in the vertical direction remains fixed.

[0018] The above embodiments are merely descriptions of preferred implementation schemes of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the design spirit of the present invention, any modification and improvement of the technical solution of the present invention made by a person of ordinary skill in the art shall fall within the protection scope of the present invention.
