BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a structural schematic diagram of a coal feeder tensioning force adjustment handle in one embodiment of the present disclosure. DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, one aspect of an embodiment of the present disclosure provides a coal feeder tensioning force adjustment handle 100 , including a handle body 110 , an adjustment member 120 and a handle member 130 .

[0024] The first end of the handle body 110 is fixedly connected to the handle member 130 , and the second end of the handle body 110 is fixedly connected to the adjustment member 120 .

[0025] When the belt of the coal feeder slips, the adjusting member 120 is used to match and connect with the end of the tensioning device of the coal feeder to adjust the tensioning force.

[0026] The coal feeder tensioning force adjustment handle and adjustment system of the disclosed embodiment include a handle body, an adjustment member and a handle member; the first end of the handle body is fixedly connected to the handle member, and the second end of the handle body is fixedly connected to the adjustment member; wherein, when the belt of the coal feeder slips, the adjustment member is used to match and connect with the end of the coal feeder tensioning device to adjust the tensioning force. When the belt of the coal feeder slips, the coal feeder tensioning force adjustment handle is used on-site to adjust the coal feeder tensioning force without disassembling the coal feeder, which is convenient to operate, does not require shutdown, and the unit load will not be limited.

[0027] Exemplarily, the end of the adjusting member 120 is provided with a first clamping portion 121, and the end of the tensioning device is provided with a second clamping portion. When adjusting the tensioning force, the first clamping portion 121 is clamped on the second clamping portion.

[0028] In this embodiment, by clamping the first clamping portion on the second clamping portion, the coal feeder tensioning force adjustment handle can be fixedly connected to the end of the coal feeder tensioning device to better adjust the tensioning force.

[0029] For example, Figure 1 As shown, in this embodiment, the first clamping part 121 is a hexagon socket nut, and the second clamping part is a hexagon head bolt. The hexagon socket nut is clamped on the hexagon bolt to achieve the fixation of the coal feeder tensioning force adjustment handle and the end of the coal feeder tensioning device.

[0030] It should be noted that the present embodiment does not specifically limit the specific structures of the first clamping portion and the second clamping portion, and they can be selected according to actual needs.

[0031] For example, in this embodiment, the diameter of the hexagon socket nut ranges from 3 cm to 5 cm. The diameter of the hexagon socket nut matches the diameter of the hexagon head bolt and can be selected according to actual needs.

[0032] For example, Figure 1 As shown, the diameter of the adjusting member 120 is larger than the diameter of the handle body 110. The larger diameter of the adjusting member 120 allows for a better arrangement of the first clamping member 121 at the end of the adjusting member 120.

[0033] For example, Figure 1As shown, the second end of the handle body 110 extends in a direction away from the adjustment member 120 and then bends and extends toward the handle member 130, so that the extension direction of the adjustment member 120 is parallel to the extension direction of the handle member 130. In other words, the handle body 110 is S-shaped.

[0034] In this embodiment, the handle body is S-shaped. It is more convenient to hold the handle member 130 and rotate the handle body 110 to provide a rotational force for the adjustment member 120 to adjust the tensioning force.

[0035] For example, Figure 1 As shown, in this embodiment, the handle 130 may be in a spindle shape. The handle 130 is in a spindle shape, which can be more convenient to grasp and thus better exert force.

[0036] Exemplarily, in this embodiment, a plurality of anti-slip grooves are provided on the surface of the handle 130, so as to increase the friction between the handle 130 and the hand when the hand holds the handle 130.

[0037] Another aspect of the disclosed embodiment provides a coal feeder tensioning force adjustment system, including a coal feeder tensioning device and the above-mentioned coal feeder tensioning force adjustment handle 100. The specific structural features of the coal feeder tensioning force adjustment handle 100 have been described in detail above and will not be repeated here.

[0038] The end of the coal feeder tensioning device extends to the outside of the coal feeder end cover; wherein,

[0039] When the belt of the coal feeder slips, the adjusting member 120 of the coal feeder tensioning force adjusting handle 100 is matched and connected with the end of the tensioning device to adjust the tensioning force.

[0040] For example, in this embodiment, a hexagonal bolt is provided at the end of the tensioning device, and a second clamping portion is provided at the end of the adjusting member 120. Preferably, the second clamping portion can be a hexagonal nut. When adjusting the tensioning force, the hexagonal nut at the end of the adjusting member 120 is clamped on the hexagonal bolt at the end of the tensioning device, and then the tensioning force adjustment handle of the coal feeder is fixedly connected to the tensioning device to achieve the adjustment of the tensioning force.

[0041] It should be noted that the second clamping portion of the tensioning device may be other structures as long as it matches the first clamping portion 121 of the adjusting member 120 , and may be selected according to actual needs.

[0042] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of the present disclosure, and these modifications and improvements are also considered to be within the protection scope of the embodiments of the present disclosure.
