Electric micro-tiller

Abstract

The invention relates to an electric micro-tiller. The electric micro-tiller comprises a complete machine; the complete machine comprises an engine base main-body, a motor base, a motor, a motor shell, a reducer, rakers, a mudguard, an adjustment lever, a handle, and wheels; an auxiliary wheel mechanism is mounted at the bottom of the reducer; a mounting tube is arranged under the rear part of theengine base main-body; a wheel support is inserted in the mounting tube, and a quick-release pull pin is inserted so as to have the wheel support fixed; the wheel support is provided with wheel shaftholes; hub motors are mounted inside the wheels; a bracket is mounted on the engine base main-body; gear holes are arranged on an angle adjusting unit; and a spray device, which realizes telescopic adjustment through the quick-release pull pin, is arranged on the bracket. The complete machine is further equipped with an electronic control system which is capable of realizing switch between frontdrive and rear drive, and is composed of a front drive circuit and a rear drive circuit; and manual control as well as remote control can be achieved for a motor of the front drive. The electric micro-tiller disclosed by the invention is convenient for quick disassembly, assembly and function adjustment so that a variety of work scenarios can be adapted; the electric micro-tiller is capable of reducing work intensity of operators on both cultivated and non cultivated roads; and moreover, the electric micro-tiller is intelligent, and relatively good in movable sprinkling effects.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to an electric tiller. Background technique [0002] Due to its small size and other advantages, micro tillage machines are widely used in hilly areas, greenhouses and other environments where it is difficult to use large and medium-sized agricultural machinery. According to the different power devices, micro tillage machines are mainly divided into internal combustion engine micro tillage machines and electric micro tillage machines. At present, the models used are mainly the former, and the related technologies are more mature. However, when the micro tillage machine with internal combustion engine is in operation, relatively strong vibration will be generated, which makes the labor intensity of the operator high. In addition, when the micro-tiller with internal combustion engine is used in the greenhouse, the noise and harmful exhaust gas...

AI Technical Summary

Problems solved by technology

[0005] 1. It is difficult to push and walk on ordinary roads. The existing technology is to replace the tiller with rollers to achieve the purpose of driving. The whole process of replacing the rollers is cumbersome and very inconvenient

Of course, in the prior art, auxiliary wheels are also installed behind the cultivating blade. When pushing to walk, the operator needs to press down the handle to transfer all the weight on the auxiliary rollers, and rely on the auxiliary rollers to push the walking, which is more difficult to operate.

For example, the Chinese invention patent with the notification number CN102934542B discloses a micro tillage machine. This micro tillage machine realizes the switching between the plow depth adjustment lever and the wheel when walking or tilling, but it needs to press down the micro tillage when pushing on the road. The handle of the machine is more inconvenient to operate

[0006] 2. The handle of the micro tillage machine cannot be flexibly adjusted up and down or up and down, and cannot adapt to people of different heights. Of course, some micro tillage machines can be adjusted, but special tools such as wrenches are required for adjustment. The adjustment efficiency is low and the operation is troublesome.

[0007] 3. The micro tillage machine cannot adjust the relative height between the rotary blade and the wheel (that is, the depth of the rotary tillage), and cannot adapt to the cultivation needs of different geology or different crops

However, this structure is more complicated, the manufacturing cost is higher, and it does not meet the market demand

[0008] 4. Operators need to go to the ground to operate when farming, hold the handle at all times, and cannot control it by hand. The operation is long-term and the work intensity is high. Because the working environment of farming is often relatively harsh, there are certain potential safety hazards

Although this kind of tillage machine has reached a certain degree of intelligence, it still requires operators to follow the operation all the time, and the whole operation process is relatively inconvenient.

[0009] 5. With the development of agricultural equipment technology, micro-tillers have more and more functions, so micro-tillers that can be sprayed appear on the market. However, the existing micro-tillers have poor spraying effects and cannot uniformly spray crops. Spraying, the height of spraying cannot be adjusted, and the use effect is poor. During the process of tillage and spraying, it is easy to spray to the operator, especially when spraying pesticides, which will cause damage to the operator and is not reasonable enough
