Description

A control handle for a plant protection machine

technical field

The utility model relates to the field of agricultural machinery, in particular to a control handle for a plant protection machine.

Background technique

Rotary tiller is a kind of tillage machine used for plowing and harrowing. It has the characteristics of strong soil breaking ability and flat surface after plowing. It provides a good seed bed and has been widely used.

A differential is installed on the current rotary tiller and other driving vehicles, and the differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive the four wheels, all the wheels must be connected, if the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving in a curve, in order for the car to drive in a curve The rotation speed is basically the same, at this time, it is necessary to add an intermediate differential to adjust the speed difference between the front and rear wheels.

In addition, in order to ensure that the vehicle can travel straight, a differential lock is provided on the differential. The function of the differential lock is to improve the passing ability of the car on bad roads, that is, when one drive axle of the car is idling, it can be quickly locked. The differential makes the two drive axles rigidly connected.

Differentials and differential locks are also used on tracked vehicles. The track wheels on the left and right sides are connected to half shafts, and the differential connects the two half shafts. When the vehicle needs to drive in a straight line, the differential lock is turned on, and the differential lock locks the differential. The speed of the crawlers on both sides is the same. When the differential lock is turned off, the crawlers on the left and right sides can travel at different speeds. When the speeds of the crawlers on one side and the other are different, the vehicle will turn towards the crawler with a lower speed, and the vehicle can be turned at this time.

Setting the crawler belt 2 on the rotary tiller can make the rotary tiller more convenient to walk in the farmland. The following is a brief introduction to the crawler rotary tiller: the crawler rotary tiller includes a frame 1, and the lower part of the frame 1 is equipped with a crawler 2 , crawler belt 2 is provided with two groups, and is positioned at the left and right sides of vehicle frame 1 respectively, and the rotary tiller group that is used for cultivated land is also installed on vehicle frame 1.

When the tracked vehicle is turning, it is necessary to stop the crawler belt 2 on one side, and the vehicle will rotate around the stopped crawler belt 2. Therefore, the tracked vehicle can be turned by controlling one of the crawler belts 2 to brake through the brake line.

However, limited by the use and manufacturing cost of the rotary tiller, the traditional crawler steering structure cannot be applied to the rotary tiller, which makes the steering operation of the crawler rotary tiller inconvenient and needs to be improved.
