Embodiment Construction
[0011] Combine below figure 1 , figure 2 The structure of the embodiment of the present invention will be described in detail. The basic structure of the walking tractor safety braking device of the present embodiment is as follows: comprise the wheel shaft 9 supporting the support frame 10, one side of the two ends of the wheel shaft 9 is respectively equipped with a semicircular arc fixed hoop 4 relatively fixed with the frame 10, and the two ends of the wheel shaft 9 The other side is installed with semi-circular arc braking hoops 3 opposite to the corresponding fixed hoops 4 respectively. The lower end of the semicircular arc of the brake hoop 3 is connected with the corresponding fixed hoop 4 through an adjustable bolt, so the gap with the wheel shaft 9 can be adjusted by adjusting the distance between them. The middle part of the connecting bracket 2 is a door-shaped frame, and the two sides of the door-shaped frame are gradually retracted toward the front to form a f...

The invention relates to a safety brake device of a walking tractor, which belongs to the technical field of agricultural machinery. The safety brake device comprises a wheel shaft for supporting a base, wherein one side of the wheel shaft is provided with a fixed hoop, the other side of the wheel shaft is provided with a brake hoop which is opposite to the fixed hoop, the brake hoop is connected with a brake handle through the backward-extension end of a connecting support, the forward-extension end of the connecting support is hinged with one end of a connecting rod, and the other end of the connecting rod is hinged with a rocker rod foot stool which is hinged and supported on the base. When the safety brake device is in operation, the brake handle is controlled, so that on one hand, an action for holding the shaft through the hoop can be rapidly realized, and wheels of the walking tractor no longer rolls forwards; and on the other hand, the rocker rod foot stool is rapidly opened by the movement of a linkage mechanism, so that a headstock of the walking tractor is safely supported on the ground, and the forward tilting phenomenon of the walking tractor in operation in a slope field can be effectively prevented.
Description
technical field [0001] The invention relates to a safety braking device for a walking tractor, in particular to a safety braking device for a walking tractor, which belongs to the technical field of agricultural machinery. Background technique [0002] Walking tractors are used more and more widely because of their small size, low cost, and flexible and convenient operation. At the same time, the walking tractor can also be equipped with corresponding agricultural machinery and tools, which can realize plowing, rotary tillage, sowing, ditching, ridging, harvesting, etc., and can also provide power for crushing, power generation, fertilization, film covering, etc. Production efficiency, reducing production costs. [0003] However, when working on a hillside, or when transferring fields between hillsides, if the hillside slope is large, improper operation will easily cause the walking tractor to slide down the bottom of the slope, or even topple over or roll over, which will ...
