Abstract
The invention relates to a handle brake structure of a rotary cultivator. The handle brake structure comprises a handle lever, wherein a brake handle is mounted on the handle lever; the brake handle is connected with a brake line which is mounted on the side surface of the handle lever; the lower end of the brake line is connected with a brake structure; the brake structure comprises a pull slice which is rotationally connected with the bottom surface of a transmission box; a driving wheel, a driven wheel and a synchronous belt are mounted in the transmission box; a brake wheel which is located on one side of the synchronous belt is mounted at one end of the pull slice; the other end of the pull slice is fixedly connected with the transmission box through a spring; the pull slice is provided with a convex part which extends out from the side surface of the transmission box to form a groove; the convex part is connected with the lower end of the brake line. The handle brake structure is simple in structure, can be used for rapidly braking transmission systems so as to avoid accidents during misoperation, does not need to completely turn off an engine or carry out restarting operation, and has the characteristics of being high in brake speed, and simple and convenient to operate.
Description
Technical field
The present invention relates to technical field of agricultural mechanical equipment, particularly relate to a kind of rotary cultivator.
Background technology
Rotary cultivator is the cultivation machinery completing to plough, harrow operation with tractor.The features such as after having that hack ability is strong because of it, plough earth's surface is smooth, and be widely used.
At present, conventional hand-held rotary cultivator, drive coulter shaft to rotate by the actuating device of electromotor.Coulter shaft drives colter to rotate, and earth is carried out farming.Owing to lacking temporary brake device, when maloperation occurs, it is impossible to the interim rotary cultivator that stops is advanced, and can only be stopped completely by main switch, needs to restart during recovery, and it operates inconvenience.
Summary of the invention
The shortcoming that the applicant exists for above-mentioned prior art, it is provided that the handle braking structure of a kind of rotary cultivator rational in infrastructure, it has simple in construction, feature easy and simple to handle.
The technical solution adopted in the present invention is as follows:
The handle braking structure of a kind of rotary cultivator, including 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；What described brake structure included being rotationally connected with transmission case bottom surface pulls sheet, transmission case is built-in is equipped with drivewheel, driven pulley and Timing Belt, the one end pulling sheet is provided with the braked wheel being positioned at Timing Belt side, the other end is connected with transmission case by spring, pulling sheet with stretching out the protuberance of transmission case groove at side surface, protuberance is connected with the lower end of brake line.
Beneficial effects of the present invention is as follows:
The simple in construction of the present invention, can be braked drive system rapidly, it is to avoid the generation of accident during maloperation, it is not necessary to completely close electromotor and reboot operation, has the advantages that retro-speed is fast, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the stereochemical structure exploded view of the present invention.
Fig. 2 is the structure chart that the present invention is installed on transmission case.
Fig. 3 is the structure chart pulling sheet of the present invention.
Wherein: 1, handlebar；2, brake handle；3, brake line；4, driven pulley；5, drivewheel；6, transmission case；61, fluting；7, Timing Belt；8, brake structure；81, braked wheel；82, sheet is pulled；821, installing hole；822, protuberance；823, column；83, spring.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the handle braking structure of the rotary cultivator of the present embodiment, including handlebar 1, handlebar 1 is provided with brake handle 2, 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；What brake structure included being rotationally connected with transmission case 6 bottom surface pulls sheet 82, transmission case 6 is built-in is equipped with drivewheel 5, driven pulley 4 and Timing Belt 7, the one end pulling sheet 82 is provided with the braked wheel 81 being positioned at Timing Belt 7 side, the other end is connected with transmission case 6 by spring 83, and spring 83 tensioning pulls sheet 82 to keep between braked wheel 81 and Timing Belt 7 with gap；Pulling sheet 82 with stretching out the protuberance 822 of transmission case 6 groove at side surface 61, protuberance 822 is connected with the lower end of brake line 3.
As it is shown on figure 3, pull sheet 82 with installing hole 821, installing hole 821 is rotationally connected by the bottom surface of mounting seat 84 and pin 85 with transmission case 6, and braked wheel 81 is installed on the column 823 pulling sheet 82.
When the present invention works, utilizing 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 close to Timing Belt 7 and rubs therewith, it is achieved braking；When not pressing brake handle 2, spring 83 tensioning pulls sheet, keeps between braked wheel 81 and Timing Belt 7 with gap.
The simple in construction of the present invention, can be braked drive system rapidly, it is to avoid the generation of accident during maloperation, it is not necessary to completely close electromotor and reboot operation, has the advantages that retro-speed is fast, easy and simple to handle.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees claim, within protection scope of the present invention, can make any type of amendment.
