Following rotation preventing rotary blade reverse type mini-tiller

Abstract

The invention provides a following rotation preventing rotary blade reverse type mini-tiller and belongs to the field of agricultural machines. According to the following rotation preventing rotary blade reverse type mini-tiller, a conveying mechanism comprises a belt with an internal tooth groove, a worm, a wheel worm wheel and a rotary blade worm wheel, the belt with the internal tooth groove is connected between a driving wheel and a tensioning wheel in a sleeving mode, a belt stop part is connected with the tensioning wheel and clamped with the internal tooth groove of the belt of the internal tooth groove, the wheel worm wheel and the rotary blade worm wheel are connected to the front and the rear of the worm respectively, the rotating directions of the wheel worm wheel and the rotary blade worm wheel are opposite, a wheel axle and a rotary blade shaft are connected to the center of the wheel worm wheel and the center of the rotary blade worm wheel respectively, and the wheel axle and the rotary blade shaft are connected with wheels and rotary blades respectively. The function of the mini-tiller is practical, the belt with the internal tooth groove is improved and then utilized, the belt stop part is used cooperatively, the belt can not rotate in a following mode again after stopping rotating fast, and therefore the use safety of the mini-tiller is improved; a transmission mode is modified into transmission of the worm and the double worm wheels, soil after being plowed one time is more thorough and finer compared with that plowed by a traditional mini-tiller, and the plowing efficiency and the practicality of the mini-tiller are greatly improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a tiller. Background technique [0002] As a commonly used agricultural machine, the tiller is more and more widely used in China's agricultural production, and plays an increasingly important role in plowing and farming. On the one hand, in the standard requirements, when the tiller is stopped, the tiller must stop rotating within 5 seconds, otherwise the safety of the tiller will be reduced. At present, in similar micro tillage machines, flat belts without internal cogs are used. After the clutch switch is released, there is often a certain friction between the belt and the driving wheel, which often causes the belt to rotate, causing the The cultivating knife cannot stop rotating within 5 seconds. In order to prevent this kind of bad phenomenon, it is necessary to perform multiple debugging on the production line during production, but sometimes the effect cannot be achi...

Problems solved by technology

At present, in similar micro tillage machines, flat belts without internal cogs are used. After the clutch switch is released, there is often a certain friction between the belt and the driving wheel, which often causes the belt to rotate, causing the The cultivating knife cannot stop rotating within 5 seconds. In order to prevent this kind of bad phenomenon, it is necessary to carry out multiple debugging on the production line during production, but sometimes the effect cannot be achieved after debugging, which greatly wastes the operating time of the debugging station and reduces production efficiency. , so that the use safety of the finished micro tillage machine is reduced

[0003] On the other hand, in terms of transmission mode, most micro tillage machines use single worm gear transmission, that is, a worm and a worm gear are connected to each other for transmission. Being dragged forward to rotate, the rotation direction of the wheel and the tiller blade are both in the same direction and moving forward. In this case, the stay time of the tiller blade on the same plowing field is too short, resulting in a poor effect after one-time plowing. , it often needs to go back and forth to cultivate the land many times, which reduces the efficiency of the cultivated land
