The invention relates to the technical field of mini-tillers, in particular to a speed reduction walking wheel of a mini-tilter.

[ background of the invention ]

With the vigorous support and development of agricultural mechanization, the use of the mini-tiller is more and more extensive. The current traction road wheel that is used for when ploughing the machine operation a little usually includes: the wheel comprises a rim, a spoke arranged in the rim, a hub (a hexagonal tube) and blades arranged on the periphery of the rim, wherein most or all of the blades are welded outside a steel ring. Generally, the number of the blades is more in order to pull the walking wheels to walk stably, and the walking wheels of the mini-tiller are ensured to walk stably by increasing the density of the blades. Such as: a common traction travelling wheel with the diameter of 350 mm is provided with about 10 blades.

When the existing four-wheel-drive mini-tiller is operated, the front-drive four-wheel-drive mini-tiller and the rear-drive four-wheel-drive mini-tiller are adopted. The front-drive four-wheel-drive mini-tiller comprises: the traction travelling wheel is sleeved on a power output shaft of the front driving device, and the cutter is sleeved on a power output shaft of the rear driving device; the rear-drive four-wheel-drive mini-tiller comprises: the cutter is sleeved on a power output shaft of the front driving device, and the traction travelling wheel is sleeved on a power output shaft of the rear driving device. Because the four-wheel-drive mini-tiller is simple in structure and few in gear, only the fast gear, the slow gear and the reverse gear are used during operation. The gear of the traction travelling wheel is changed by manually operating a gear lever, and when an operator is a young person, the speed of the traction travelling wheel is required to be higher; when the operator is elderly, slower speeds of the traction road wheels are required. Because the gear is few, can't satisfy old person user to the slower speed requirement of pulling the walking wheel. How to realize the speed reduction of the traction travelling wheel is a problem which needs to be solved by the old user of the four-wheel-drive mini-tiller.

[ summary of the invention ]

The invention aims to provide a speed-reducing walking wheel of a mini-tiller. The speed of the walking wheel is reduced and the walking is stable by reducing the number of the blades on the rim and changing the positions of the blades on the rim.

When the number of the blades uniformly distributed on the travelling wheel of the mini-tiller is reduced to below 6, the situation that the wheel rim lands and the blades land to and fro can occur when the travelling wheel rotates. When the wheel rim lands, the friction force between the wheel rim and the ground is small, the wheel rim slips, and the mini-tiller cannot move forward; when the blades land, the climbing force between the blades and the land is large, and the micro-cultivator moves forward. It can be seen from this that: on the travelling wheels with the same rotating speed, the number of blades is large, the sliding area is small, and the travelling distance of the travelling wheel of the mini-tiller rotating for one circle is long; the blades are few, the slipping area is large, and the forward distance of the micro-cultivator walking wheel rotating for one circle is short. According to the situation, the invention provides a speed-reducing walking wheel of a mini-tiller.

In order to ensure the stable walking of the speed reduction walking wheel of the mini-tiller, the vibration of the walking wheel is reduced. The height of the blade protruding out of the steel ring is less than 25 mm. The height of the blade extending out of the outer diameter of the steel ring is reduced, so that the vibration of the blade contacting the ground instantly when the blade rotates is weakened.

In order to solve the technical problems, the technical scheme provided by the invention is as follows:

1, a plough quick-witted speed reduction walking wheel a little, includes: the wheel rim, the spoke that sets up in the wheel rim, wheel hub and the blade that sets up on the wheel rim, characterized by, the quantity of blade is limited to 2 or 3 or 4 or 5, and the height that the blade stands out outside the steel ring is less than 25 millimeters.

2, as further setting, a quick-witted speed reduction walking wheel is ploughed a little, be equipped with the bracing piece between wheel rim and the blade.

3, as further setting, plough quick-witted speed reduction walking wheel a little, wheel hub is the regular hexagon pipe, and spoke and wheel hub weld mutually.

4, as further setting, a plough quick-witted speed reduction walking wheel a little, blade evenly distributed sets up on the rim.

The invention has the beneficial effects that: a speed reduction walking wheel of a mini-tiller has a speed reduction function, and after the speed reduction walking wheel is installed on a four-wheel-drive mini-tiller for use, the mini-tiller can be driven at a slower speed when running fast, slowly or reversely, and the mini-tiller is easier to operate. The speed reduction walking wheel of the mini-tiller is adopted on the four-wheel-drive mini-tiller, so that the defect of few speed change gears of the mini-tiller can be overcome, and the mini-tiller has operation stability. Thereby expanding the speed change range of the traction swing and meeting the requirements of specific users. The invention has the advantages of ingenious design, simple structure, easy modification, low modification cost and durability.
