Flat trailer special for harvesting machinery

Abstract

The invention discloses a flat trailer special for harvesting machinery, comprising a frame and traveling wheels arranged at the bottom of the frame; a bottom plate, cross beam I, cross beam II, cross beam III and a horizontal cross beam are arranged on the frame, a mounting post is disposed on each cross beam, a driving mechanism is arranged on each mounting post, each driving mechanism is provided with driving gears, each of the driving gears on two sides of the frame is fitted with a driving rack, a hydraulic system is arranged at the center of the bottom of the bottom plate, and the hydraulic system is provided with a support disc through a lifting post; two sides of the bottom of the bottom plate are provided with tooth gaps in symmetric manner, a guide plate is arranged at the rear end of the frame, and the bottom of the guide plate is provided with a lifting mechanism. The flat trailer has the advantages that tilting slope of the bottom plate of the trailer can be controlled in suitable manner, loading and unloading of harvesting machinery and good stability of the loading and unloading processes can be effectively achieved, the bottom plate, the frame and the harvesting machinery are well guaranteed, and the flat trailer has good safety and high safety coefficient and meets the requirements on actual use.

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 large-tonnage machinery and noon consignment.

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 basically adopted in the prior art is all crawler-type harvesting machinery, and crawler-type harvesting machinery overcomes the wet problem of field acres, but crawler-type harvesting machinery is not suitable for running on potholed roads (including gravel roads), potholes (including gravel road) will cause serious damage to the crawler belt and cause 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 sliding 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.
