Abstract
The utility model relates to a kind of handle braking structure of rotovator, comprises handlebar, handlebar is provided with brake handle, and the brake line that brake handle is installed with handlebar side is connected, and the lower end of brake line is connected with brake structure; Described brake structure comprise be rotationally connected with transmission case bottom surface pull sheet, transmission case is in-built is equipped with driving wheel, driven pulley and Timing Belt, pull one end of sheet that the braked wheel being positioned at Timing Belt side is installed, the other end is connected by spring and transmission case, pull sheet with the protuberance stretching out transmission case groove at side surface, protuberance is connected with the lower end of brake line.Structure of the present utility model is simple, braking rapidly, avoid the generation of accident during maloperation, without the need to killing engine completely and reboot operation, having the advantages that retro-speed is fast, easy and simple to handle to transmission system.
Description
Technical field
The utility model relates to technical field of agricultural mechanical equipment, particularly relates to a kind of rotovator.
Background technology
Rotovator completes cultivated, to harrow operation cultivation machinery.Because of its have hack ability strong, plough after the features such as earth's surface is smooth, and to be widely used.
At present, conventional hand-held rotovator, drives coulter shaft to rotate by the transmission device of engine.Coulter shaft drives colter to rotate, and carries out farming to earth.Owing to lacking temporary brake device, when occurring maloperation, cannot rotovator be stopped to advance temporarily, can only be stopped completely by master switch, need during recovery to restart, it operates inconvenience.
Utility model content
The shortcoming that the applicant exists for above-mentioned prior art, provides a kind of handle braking structure of rotovator rational in infrastructure, and it has structure feature simple, easy and simple to handle.
The technical scheme that the utility model adopts is as follows:
A handle braking structure for rotovator, comprises handlebar, handlebar is provided with brake handle, and the brake line that brake handle is installed with handlebar side is connected, and the lower end of brake line is connected with brake structure; Described brake structure comprise be rotationally connected with transmission case bottom surface pull sheet, transmission case is in-built is equipped with driving wheel, driven pulley and Timing Belt, pull one end of sheet that the braked wheel being positioned at Timing Belt side is installed, the other end is connected by spring and transmission case, pull sheet with the protuberance stretching out transmission case groove at side surface, protuberance is connected with the lower end of brake line.
The beneficial effects of the utility model are as follows:
Structure of the present utility model is simple, braking rapidly, avoid the generation of accident during maloperation, without the need to killing engine completely and reboot operation, having the advantages that retro-speed is fast, easy and simple to handle to transmission system.

Fig. 2 is the structure chart that the utility model is installed on transmission case.
Fig. 3 is the structure chart pulling sheet of the present utility model.
Wherein: 1, handlebar; 2, brake handle; 3, brake line; 4, driven pulley; 5, driving wheel; 6, transmission case; 61, slot; 7, Timing Belt; 8, brake structure; 81, braked wheel; 82, sheet is pulled; 821, installing hole; 822, protuberance; 823, column; 83, spring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the handle braking structure of the rotovator of the present embodiment, comprises handlebar 1, handlebar 1 is provided with brake handle 2, and the brake line 3 that brake handle 2 is installed with handlebar 1 side is connected, and the lower end of brake line 3 is connected with brake structure; Brake structure comprise be rotationally connected with transmission case 6 bottom surface pull sheet 82, transmission case 6 is in-built is equipped with driving wheel 5, driven pulley 4 and Timing Belt 7, pull one end of sheet 82 to be provided with to be positioned at the braked wheel 81 of Timing Belt 7 side, the other end is connected by spring 83 and transmission case 6, and spring 83 tensioning pulls sheet 82 to keep between braked wheel 81 and Timing Belt 7 with gap; Pull sheet 82 with the protuberance 822 stretching out transmission case 6 groove at side surface 61, protuberance 822 is connected with the lower end of brake line 3.
As shown in Figure 3, pull sheet 82 with installing hole 821, installing hole 821 is rotationally connected with the bottom surface of transmission case 6 by mount pad 84 and pin 85, and braked wheel 81 is installed on and pulls on the column 823 of sheet 82.
During utility model works, utilize hand to press brake handle 2, brake handle 2 pulls brake line 3, and brake line 3 drives and pulls sheet 82 to rotate, and when pulling sheet 82 to rotate, braked wheel 81 is to Timing Belt 7 near also rubbing with it, realizes braking; When not pressing brake handle 2, spring 83 tensioning pulls sheet, keeps between braked wheel 81 and Timing Belt 7 with gap.
Structure of the present utility model is simple, braking rapidly, avoid the generation of accident during maloperation, without the need to killing engine completely and reboot operation, having the advantages that retro-speed is fast, easy and simple to handle to transmission system.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
