technical field

The invention relates to a fresh tobacco leaf handling tool, in particular to a pure electric double-drive field fresh tobacco leaf handling vehicle.

Background technique

The handling of fresh tobacco leaves in most tobacco planting areas is achieved by manual clamping, bundling and clamping. The manual handling process will inevitably bring about mutual squeezing and friction between the fresh tobacco leaves, resulting in green marks, which will cause the tobacco leaves to be cured. Dark brown spots and scratches remain, which directly affect the quality of flue-cured tobacco; at the same time, labor and time costs are high. In addition, when a large amount of tobacco leaves needs to be transported, manual transport is difficult to meet, so that it is easy to miss the best harvest time. Although a small number of wheeled trucks have been put into research and development in China, the handling efficiency has been improved, but these tobacco leaf trucks are large in size, complex in structure and fuel-driven. They are mainly suitable for plain areas, and there are also waste oil discharge fields. potential soil pollution.

Wheels 1c1 are also provided with in-wheel motors that drive their respective rotations. The lithium battery for powering the in-wheel motor can be arranged on the underside of the main frame of the chassis.

When in use, put the picked fresh tobacco leaves into the tobacco frame 2, and the hub motor drives the driving wheels 1c1 to rotate forward/backward in the field respectively; after picking one frame, stack a new frame and continue picking. Tobacco leaves are transported back to their destination, and after the frame is removed, it is replaced with an empty frame to continue picking.

The aforementioned steering assembly 1b includes steering wheels 1b1 arranged on both sides of the front end of the chassis main frame 1a. The two steering wheels 1b1 are respectively connected with front wheel axle brackets 1b2, and the two front wheel axle brackets 1b2 are respectively connected to the chassis main frame 1a through the steering fixed axle 1b3. Rotationally connected, the two steering fixed shafts 1b3 are also connected by a three-link steering mechanism 1b4.

During steering, the three-link steering mechanism 1b4 is toggled to make the two steering wheels 1b1 swing around their respective steering fixed shafts 1b3 to realize steering.

The front end of the aforementioned chassis assembly 1 is also provided with a front console 3, and the front console 3 includes a front steering support plate 3a fixed on the front end of the chassis main frame 1a, and a front steering support shaft 3b is rotatably connected to the front steering support plate 3a.

The principle of the above-mentioned rear steering lever 4d to toggle the three-link steering mechanism 1b4 is the same as that of the front steering lever 3d; the principle of the movable connection structure is also the same.

The front and rear steering levers are all set at the same position to switch the three-link steering mechanism 1b4, so that the front and rear workstations (front and rear consoles) can be operated in the same direction. Turn the front steering support rod 3c to the left, the steering wheel 1b1 turns left, the whole vehicle turns left, and the same is true for the right; The structure realizes the straight forward and straight back of the truck, and the control of the front and rear ends conforms to the control logic of the human-machine in the same direction, and the operation is more convenient.

On both sides of the aforementioned chassis main frame 1a, there are also flexible auxiliary wheels 1d between the steering assembly 1b and the driving assembly 1c.

Both the aforementioned front wheel axle frame 1b2 and the rear wheel axle frame 1c2 are provided with damping springs 5 .

The top of the aforementioned cigarette frame 2 is also provided with hanging ears 6 of the tobacco leaf tying band.

The front steering support rod 3c is provided with a front control panel 3e at the top, and a front operation button 3f is arranged on the front control panel 3e. The front control panel 3e is also connected with a front steering control handle 3g for twisting the front steering support rod 3c.

A rear control panel 4e is arranged on the top of the aforementioned rear steering support rod 4c, and a rear operation button 4f is arranged on the rear control panel 4e. The rear control panel 4e is also connected with a rear steering control handle 4g for twisting the rear steering support rod 4c.

The structure of the control handle 4g can be a steering lever (see FIG. 1 ), or a steering wheel structure.

The average carrying capacity of the aforementioned cigarette frame 2 is 15kg of fresh tobacco leaves; the walking speed of the truck includes fast and slow; the slow speed is the normal walking speed of adults; the fast speed is 1.5 times the normal walking speed. The bearing weight and speed settings fully take into account the extrusion and friction damage of the tobacco leaves during transportation; through the bearing weight and speed settings, the stacking of tobacco leaves can be too heavy to cause crushing injuries, and at the same time, it can also avoid bumps during transportation and walking. damage to ensure the quality of tobacco leaves.

The invention fully considers human-machine friendly interaction, considers the large amount of tobacco farmers picking tobacco leaves, the dense tobacco leaves in the tobacco field, and the inconvenience of the operator going back and forth between the front and rear ends of the truck. The button provides the operator with two-speed shifting (slow/fast), stop and start, which is convenient for the operator to control according to the actual situation of the tobacco field. The two speeds are respectively set at the adult walking speed (slow speed) and 1.5 times the human walking speed (fast). The steering control handle is used for the operator to control the steering and U-turn of the truck. In addition, the control handle of the handlebar structure can provide a handle for the operator to stabilize the center of gravity of the vehicle in emergency situations.
