The utility model discloses in, the belt pulley also makes the blade rotate when driving belt pivoted, and the blade rotates and forms the heat dissipation air current and dispels the heat to belt pulley self, and the rotation that the blade was not stopped has also avoided dust weeds etc. to pile up on interior cavity rotating parts and then lead to spare part to damage.
Description
Technical Field
The utility model particularly relates to an agricultural machine's heat dissipation belt pulley.
Background
In agricultural machinery, belt pulleys are important parts in mechanical transmission, most belt pulleys are in a structure that a belt groove is machined in the outer circular surface of each belt pulley, when the belt pulley is used, a belt is embedded into the belt groove on each belt pulley to rotate, however, in the rotating process of each belt pulley, the friction between the two side wall surfaces of the belt groove on each belt pulley and the two sides of the belt generates heat to easily damage the belt, dust is more in the working environment of the agricultural machinery, the phenomenon that the heat dissipation is poor due to the wrapping of the belt pulleys and the accumulation of weed dust of moving parts in the inner cavity of each belt pulley is caused, and further the moving parts in the inner cavity of each belt pulley are damaged.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the not enough of above prior art, provide a agricultural machine's heat dissipation belt pulley, including installing in the epaxial belt pulley of main, the belt pulley in be equipped with axial belt pulley inner chamber, belt pulley inner chamber coaxial arrangement have interior cavity rotating parts, install a plurality of blades that are the arc and buckle on the inner wall of belt pulley inner chamber, the blade encircle outside the circumference of interior cavity rotating parts and with interior cavity rotating parts at a distance of certain distance.
Furthermore, the inner cavity body rotating part comprises a bearing and a main shaft sheath which are sleeved on the main shaft, and the front section of the main shaft sheath is clamped on a hub of the belt pulley.
Furthermore, the bearing is two deep groove ball bearings arranged side by side.
Furthermore, an L-shaped bending mounting head is arranged at one mounting end of the blade, and the mounting head is attached to the inner wall of the inner cavity of the belt pulley and fastened through a bolt.
Furthermore, a spring washer is arranged between the bolt and the mounting head of the blade.
Further, the tip of the blade is bent in a clockwise direction.
Furthermore, the blade is a bent steel plate. The blade is bent by adopting a steel plate, is convenient to manufacture and simple in structure, and saves cost
Has the advantages that: the utility model discloses in, the belt pulley also makes the blade rotate when driving belt pivoted, and the blade rotates and forms the heat dissipation air current and dispels the heat to belt pulley self, and the rotation that the blade was not stopped has also avoided dust weeds etc. to pile up on interior cavity rotating parts and then lead to spare part to damage.
Drawings
FIG. 1 is a schematic cross-sectional view of a heat dissipating pulley of an agricultural machine;
in the figure: 1. the belt pulley comprises a belt pulley body, 2, a belt, 3, blades, 4, a belt pulley inner cavity, 5, an inner cavity rotating part, 6, a bolt, 7, a spring washer, 8, a bearing, 9 and a main shaft sheath.
Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1, the heat dissipation belt pulley of the agricultural machine comprises a belt pulley 1 mounted on a main shaft, wherein an axial belt pulley inner cavity 4 is arranged in the belt pulley 1, an inner cavity rotating part 5 is coaxially mounted in the belt pulley inner cavity 4, a plurality of blades 3 bent in an arc shape are mounted on the inner wall of the belt pulley inner cavity 4, and the blades 3 surround the circumference of the inner cavity rotating part 5 and are at a certain distance from the inner cavity rotating part 5; the blade tip of the blade 3 is bent towards the clockwise direction; an L-shaped bent mounting head is arranged at one mounting end of the blade 3, the mounting head is attached to the inner wall of the inner cavity 4 of the belt pulley and fastened through a bolt 6, and a spring washer 7 is arranged between the bolt 6 and the mounting head of the blade 3.
In this embodiment, the inner cavity rotating part 5 includes a bearing 8 and a spindle sheath 9 sleeved on the spindle, and a front section of the spindle sheath 9 is clamped on a hub of the belt pulley 1; the bearing 8 is two deep groove ball bearings arranged side by side.
In this embodiment, the blade 3 is a bent steel plate.
The belt pulley also makes the blade rotate when driving belt pivoted, and the blade rotates and forms the heat dissipation air current and dispels the heat to belt pulley self, and the rotation that the blade does not stop has also avoided dust weeds etc. to pile up on interior cavity gyration part and then lead to spare part to damage.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
