A special flatbed trailer for harvesting machinery

Abstract

The invention discloses a platform trailer special for harvesting machines. The platform trailer comprises a trailer framework and traveling wheels arranged at the bottom of the trailer framework. The trailer framework is provided with a trailer bottom plate, a first cross beam, a second cross beam, a third cross beam and a horizontal cross beam; the cross beams are all provided with placing columns which are provided with driving mechanisms; driving gears are arranged on the driving mechanisms; and driving racks are arranged on the driving gears on the two sides of the trailer framework. A hydraulic system is arranged in the middle of the bottom of the trailer bottom plate and is provided with a supporting disc through lifting columns; gear openings are formed in the two sides of the bottom of the trailer bottom plate symmetrically; guide plates are arranged at the rear end of the trailer framework; and lifting mechanisms are arranged at the bottoms of the guide plates. According to the platform trailer, the tilting slope of the trailer bottom plate of the trailer can be controlled properly, so that the harvesting machines are effectively loaded and unloaded, and the stability in the loading and unloading process is maintained; and the trailer bottom plate, the trailer framework and the harvesting machines are well guaranteed, good safety performance and a high safety coefficient are achieved, and practical use demands are met.

Description

technical field [0001] The invention relates to the technical field of harvesting machinery consignment equipment, in particular to a special flatbed trailer for harvesting machinery. Background technique [0002] With the emergence of large-tonnage objects, the machinery used to consign large-tonnage objects also rises. Because the consignment of large-tonnage objects requires a lot of manpower, material and financial resources, the appearance of trailers greatly saves manpower, material and financial resources. Financial resources, so trailers are an indispensable tool in future life and production, and play a vital role in the consignment of large-tonnage machinery and heavy objects.

Problems solved by technology

[0003] At present, a relatively traditional hoisting machinery trailer structure includes a trailer frame and a walking system. The walking system is arranged at the bottom of the frame to support the weight of the entire trailer and realize the movement of the trailer. Tonnage heavy objects, although the trailer with this traditional structure can be consigned, but how to transport large tonnage heavy objects to the bottom plate on the frame of the car and how to unload them is a difficult problem, which requires a lot of labor and the cooperation of cranes, so not promoted

Nowadays, agricultural development has received great attention, and agricultural production is gradually moving towards mechanization, especially harvesting machinery. The mechanical harvesting in traditional technology uses tire-type harvesters, and tire-type harvesting machinery is only suitable for dry ground in the field. Popularize and use; What adopted basically in the prior art is all crawler-type harvesting machinery, and crawler-type harvesting machinery has overcome the wet problem of field acres, but crawler-type harvesting machinery is not suitable for traveling on bumpy roads (comprising gravel roads), potholed roads (including gravel road) will cause serious damage to the crawler belt, resulting in large economic losses. In addition, the crawler harvesting machinery is too slow to drive on the road, so it needs to be transported by a trailer

In the trailer in the prior art, a hydraulic system is installed on the vehicle frame, and a telescopic rod is arranged on the hydraulic system. One end of the telescopic rod is connected with the bottom of the bottom plate, so that when unloading heavy objects, the hydraulic system drives the telescopic rod to move the bottom plate. Jack up to make it tilt, and then the harvesting machinery will slide down along the slope. However, because the length of the trailer with this structure is fixed, it is impossible to properly control the inclination angle of the bottom plate. When the inclination angle of the bottom plate is too large , due to the inertia of the hoisting machinery, the impact force during the slide process is too large, which will cause collision damage and pose a great safety hazard; in addition, due to the heavy weight of the harvesting machinery, the contact area between the walking system (ie tires) and the ground is limited. The strength to bear is relatively small, so most of the weight of the harvesting machine will be concentrated in the middle of the bottom plate, which will cause breakage and damage to the middle of the bottom plate for a long time, resulting in certain economic losses, etc.
