DETAILED DESCRIPTION

[0018] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0019] As shown in the drawings, Figs. 1-2 The present application discloses a tensioning mechanism for a conveying belt of a huller, which comprises a tensioning mounting support 801, one side of the tensioning mounting support 801 is provided with a rotating arm 802 which rotates relative to the tensioning mounting support 801 through a rotating shaft 803, a tensioning wheel 804 is arranged on the rotating arm 802, and an elastic adjusting assembly 805 is arranged between the rotating arm 802 and the tensioning mounting support 801.

[0020] In the embodiment, the elastic force adjusting assembly 805 comprises a spring 8051, both ends of the spring 8051 are connected with the tension mounting support 801 and the rotating arm 802 respectively.

[0021] In the embodiment, both ends of the spring 8051 are provided with first connecting parts 80511 respectively, the spring 8051 is connected with the tension mounting support 801 and the rotating arm 802 through the first connecting parts 80511 respectively.

[0022] In the embodiment, the side of the tension mounting support 801 is provided with a first connecting assembly 806, the first connecting assembly 806 comprises a first connecting rod 8061, the first connecting part 80511 of the spring 8051 is connected with the first connecting rod 8061, the end of the first connecting rod 8061 away from the tension mounting support 801 is provided with a limiting nut 8062 for limiting the first connecting part 80511 of the spring 8051 from moving to the outside of the first connecting rod 8061.

[0023] In the embodiment, the rotating arm 802 is provided with a second connecting part 8021, the second connecting part 8021 is connected with the first connecting part 80511 of the spring 8051 through a second connecting assembly 8022.

[0024] In the embodiment, the second connecting assembly 8022 comprises a second connecting rod 80221 connected with the second connecting part 8021, the end of the second connecting rod 80221 away from the second connecting part 8021 is provided with a third connecting part 80222, the third connecting part 80222 is connected with the first connecting part 80511 of the spring 8051.

[0025] In the embodiment, the end of the second connecting rod 80221 away from the spring 8051 is provided with an adjusting hand wheel 808.

[0026] In the embodiment, the side of the tension mounting support 801 away from the rotating arm 802 is provided with a reinforcing plate 807.

[0027] The mechanism is installed in the huller through the tension mounting support 801.

[0028] The tensioning wheel 804 contacts with the conveying belt, that is, the conveying belt passes through the tensioning wheel 804, and the conveying belt is tensioned when displacement, relaxation, skidding and wear of the conveying belt occur.

[0029] When the mechanism is installed, the end of the second connecting rod 80221 away from the spring 8051 extends to the outside of the huller, and the adjusting hand wheel 808 is also installed on the outside of the huller, so that manual adjustment is facilitated.

[0032] The outer surface of the tensioning wheel 804 is provided with grooves matched with the conveying belt, so as to enhance the friction between the tensioning wheel 804 and the conveying belt and improve the transmission stability.

[0033] When the conveying belt is displaced, loosened, slipped, worn or the like, the tension of the conveying belt will be changed accordingly.

[0034] During the transmission of the conveying belt, if the conveying belt is loosened and the tension is reduced, the tensioning wheel 804 will further press the conveying belt under the elastic force of the spring 8051; if the tension of the conveying belt is too large, the tensioning wheel 804 will overcome the elastic force of the spring 8051 to further deform the spring 8051, so as to adjust the tensioning degree and always keep the conveying belt in a proper tensioning state.
