Description

Technical Field

[0001] The invention relates to the field of agricultural and forestry equipment, and in particular to a novel suspension tractor. Background Art

[0002] Traditionally, bananas are harvested and transported to processing plants manually. The bunches are easily damaged, bumped or scratched by machinery, and other sponge mats or banana leaves need to be laid on the ground. The process is complicated and labor-intensive.

[0003] At present, a transmission cableway type of transportation is also adopted, and its power source is usually towed by a tractor head. During transportation, the fruit ears are placed on a cargo device, and the tractor drives the cargo device from the starting end to the terminal. Its defects are: first, after unloading at the terminal, the tractor and the cargo device need to be removed, and the tractor itself has no power and cannot travel on the road. The above parts need to be placed in a transport vehicle (walking tractor, etc.) and sent back to the starting end from the terminal; second, after the transport vehicle is transported, the tractor and the cargo device are placed on the cableway at the starting end, and the driver himself needs to drive the tractor to transport the fruit ears, and the transport vehicle needs another specific driver to return to the terminal from the starting end along the farmland road, and the personnel input is relatively large; third, the roads in the farming area are bumpy and rugged, and some sections are very narrow, so the transport vehicle is not suitable for transportation on some sections, and two people are often used to carry the goods on their shoulders, which makes transportation difficult; fourth, the transport vehicle or the person carrying the goods on their shoulders is slow, dangerous, and easily causes a stop, low production efficiency, and easily causes the fruit ears to be squeezed if they are not transported in time. Summary of the invention

[0004] In order to solve one or more of the above problems, the present invention provides a novel suspension tractor.

[0005] According to one aspect of the present invention, the novel suspension tractor comprises a track, a bracket, a cargo device and a driving device, wherein a plurality of brackets are fixed on the ground, a track is fixed on the upper end of the bracket, a plurality of cargo devices are detachably hung on the track, adjacent cargo devices are connected by a connecting rod, and objects can be hung on the lower end of the cargo device.

[0006] The driving device includes a traction part, a transmission part, a frame and a rolling part. Both ends of the frame are provided with traction hooks, which are connected to the ends of adjacent connecting rods.

The other end of the rotating arm is connected to the two ends of the upper side of the frame. Rotating the rotating arm can move the roller up and down, so that the roller is off the track or in contact with the track.

[0009] After the rollers descend and contact the track, they will drive the traction part to rise and make it leave the ground. The transmission part can transmit the driving power of the traction part to the rolling part, which can make the rolling part move along the track, thereby driving the cargo device to move from the starting end to the end end.

[0010] When the roller rises and leaves the track, the traction part descends to contact the ground, the drive device can be moved out of the track, the traction part is started, and the drive device can travel along the ground and return from the terminal to the starting end.
