Wide-range horizontal mini-tiller for avoiding middle tillage omission by adopting guide wheel matched lift-throwing type plow with blade protecting disc

Abstract

A wide-range horizontal mini-tiller for avoiding middle tillage omission by adopting a guide wheel matched lift-throwing type plow with a blade protecting disc adopts combination of a guide wheel (p9) and the lift-throwing type plow (p104) and serves as a novel tool applying front guide wheel matched plow to avoid middle tillage omission. Various safety measures are provided. By using a safe follow-up upper protective plate, a safe follow-up rear protective plate and left and right safe protective frames, the mud sticking amount is decreased, entangled grass is cut off, the work efficiency is improved, the mini-tiller is safe and up to the standard, and observation is facilitated. A safe resistance fork wheel does not easily incline and is easy to guide, movable protective plates are provided with detachable plates, and the transportation cost can be reduced. The mini-tiller is proved with a reverse gear and facilitates usage of an operator on the cultivated land edge, a handle is provided with an anti-misoperation device, the handle height is adjustable at high level, middle level and low level, a horizontal angle of the handle is adjustable at five levels, the height of a mud blocking rod is adjustable in vertical four levels, and rotary blades have overlapping phase difference and end teeth and facilitates sharpening of sawtooth blades. The safety is further improved by using the outer protective disc. In addition, due to the fact that the outer protective disc is a function wave protective disc and bounces when being pressed to deform, the mini-tiller has the effects of wide-range vibration reduction, vitality enhancing and multiple-point balancing. The guide wheel matched lift-throwing type plow provided with the blade protecting disc has the effect of avoiding the tillage omission.

Description

technical field [0001] The invention relates to an agricultural and animal husbandry machine, which belongs to the technical field of rotary tillers, in particular to a rotary tiller with various safety measures, which is a wide-ranging machine with a guide wheel for a blade guard plate and a channeling type plow to eliminate missing tillage. horizontal tiller. Background technique [0002] Food is the most important thing for the people; in farming, the more important labor is plowing the fields. The traditional employment of people or cattle as the main labor is not only labor-intensive, but also extremely inefficient. For land, especially for hills and mountainous areas, the continuous development and improvement of various rotary tillers plays an important role in reducing the labor intensity of farmers and improving efficiency. Rotary cultivators are widely used in the mode of sometimes self-propelled sometimes not self-propelled by people's preferences to carry out op...

AI Technical Summary

Problems solved by technology

But, first of all, the starting handle of the existing rotary tiller, also known as the flameout handle, is opened when held, and there is no misuse protection measure. When the starting handle is accidentally pressed, the rotary knife will rotate, which does not meet the safety requirements high requirements

Secondly, the fender device of the existing rotary cultivator generally just simply arranges the fender on the top of the rotary tiller, and the fender is fixed on the body, and there are obvious deficiencies in the use process: one is because the fender Only cover the top of the rotary tiller, the dust is flying when the rotary tiller is working, the dust is large, and the working environment is poor, which directly affects the health of the operator. The third is that it is easy to stick to mud. Because the fenders of various rotary tillers are made of metal plates, the extruded soil is mixed with grass roots and sticks to the fenders firmly. Strong friction occurs, which increases power consumption and accelerates the wear of the rotary tiller. The sticky clay on the fender needs to be scraped off manually with a tool shovel, which is time-consuming and laborious and affects the efficacy. One of the reasons is that the fender It is fixed, and there are no solutions such as movable or follow-up upper fenders and movable rear fenders; the fenders are fixed, and there is a special case, which is fixed during rotary tillage operations, only It is easy to install and replace. For example, utility model 200920244006.8, a rotary tiller with an openable top cover, which consists of: the main body of the rotary tiller, which is characterized in that: the upper cover of the main body of the rotary tiller includes a The connected movable upper cover plate has a lock on the upper cover plate; the upper cover plate is fixed during operation, which is the same as the movable and follow-up upper fender and the movable rear fender during operation of the present invention. There are essential differences in solutions such as fenders and left and right protection

Fourth, it is easy to get entangled with grass during rotary tillage, that is because the fenders of various rotary tillers have no cutting edge measures

Because the channeling type plow is usually installed in front of the rotary tiller box, but it has a significant effect when used in front of the rotary tiller box driven by a larger tractor; and the handrail operated by a single person is very long and the leverage is great. When the forward direction of the front of the rotary tiller box and the direction of the up and down swing head are swaying a lot, the channeling type plow is intermittently tied down and sometimes lifted

And if the working parts such as plow and shovel with simple structure and easy manufacture are installed in the lower part of the box body, the effect is not ideal.

Mengan's swing-type or inclined-plane eccentric bushing-type device for eliminating missing tillage is complex and mostly used in large-scale rotary tillers, which is difficult to complete on microcomputers
