Multifunction hydraulic agricultural vehicle

Abstract

The mechanical transmission of the vehicle all adopts hydraulic transmission. A walking part of the vehicle adopts a single coupling shaft and a double coupling shaft and forms the situation of being wheel-by-wheel and power-by-power (four-wheel and four-drive). A front shaft is a single coupling shaft, an arch bridge is upward and the central part is provided with a vertical shaft. The function of the vertical shaft is to move two wheels from transverse to consequent to 90 degrees, the wheels rotates under stress application, the vehicle body can be pulled, a back wheel is taken as a central point to change the front of the vehicle into the back thereof, thus completing 180-dgree turn and ensuring that the vehicle takes place exactly and returns back to the cultivated direction and position after the turn. A back shaft is the double coupling shaft. In order to reduce water loss and soil erosion and increase the buffering power of soil against rain water, the cultivation crossing to mountains is adopted for hilly lands. Therefore, the vehicle body can be inclined to heavier side when cultivating the hilly lands, the weight of the vehicle body is moved to low wheels and the high wheels losing gravity and adhesion to the ground slide and idle, thus causing the phenomenon of deviating from a cultivation ridge path or not walking of a rotary vehicle and bringing great difficulty for implementing mechanization. Consequently, in order to adapt the cultivation in a mountain area, the middle position of the length of the vehicle body is specially and additionally provided with a sliding iron counterweight accounting for 30 percent of the total weight of the vehicle body. When the vehicle cultivates the hilly lands transversely, the sliding iron counterweight can correspondingly move to a higher position under the control of a vertical automatic switch and presses the weight on the high wheels so as to lead the gravities of high and low wheels to be the same or similar.

Description

technical field [0001] The invention is a large-scale agricultural production tool with multiple functions, which belongs to the field of E2 automobile key parts and H11 agricultural machinery. A total of nine innovations are involved, and all workmanship adopts hydraulic transmission. When cultivating, it can turn around 180° on the spot, and accurately return to the position, which can improve agricultural productivity and lay the foundation for high and stable yield. Background technique [0002] The existing agricultural machinery for cultivation has a single function, and there is a problem that it cannot be used on hillsides. The present invention comprehensively combines the existing agricultural machines, develops single functions into multi-functions, and can be used in both plains and mountainous areas. [0003] Existing agricultural machines all adopt the toothing function, which is difficult to adapt to multiple workmanship in many places. The invention adopts...
