Problems solved by technology

[0002] At present, most large-scale grassland weeding work is carried out by hanging a mowing platform behind the tractor. This kind of mowing platform generally has a mowing width of 2.4 meters to 3.6 meters. Because the mowing platform is connected behind the tractor, when compounding, except the middle The connection adopts rigid pin connection, and other auxiliary connections adopt steel wire soft connection. The mowing platform of this kind of connection needs to reach a certain weight to ensure the stability of the whole mowing platform during mowing, and the adjustment of the mowing height needs to be manually adjusted; at the same time, from the tractor The power shaft coming out is directly connected to the gearbox, which also makes it very troublesome to replace the belt on the mowing platform

Abstract

Disclosed is a middle mowing platform controlled by a servo motor to ascend or descend. The middle of a frame is provided with a groove for mounting a mowing platform body. The two ends of the groove are provided with extended support frames for hanging the mowing platform on a tractor respectively. One end of each mowing platform guide rod is fixed on the mowing platform body, and the other end of each mowing platform guide rod is embedded into the frame. One end of a mowing platform lifting screw rod is fixed on the mowing platform body, and the other end of the mowing platform lifting screw rod is embedded in the frame. Besides, the mowing platform lifting screw rod is located in the middle of the mowing platform guide rods on which chain wheel nuts are mounted. A mowing platform lifting servo motor is connected with the chain wheel nuts through chains. Therefore, the mechanical structure of the mowing platform is effectively simplified, and the weight of the mowing platform is significantly reduced. Four mowing platform guide rods are adopted for assisting guiding, so that the mowing platform is enabled to stably ascend and descend in a horizontal plane. Through the mowing platform servo motor, the infinite ascending and descending of the mowing platform are achieved, so that the labor intensity of mowers is drastically reduced.

Description

technical field [0001] The invention relates to the technical field of mowing auxiliary devices, in particular to a middle-mounted mowing platform whose elevation is controlled by a servo motor. Background technique [0002] At present, most large-scale grassland weeding work is carried out by hanging a mowing platform behind the tractor. This kind of mowing platform generally has a mowing width of 2.4 meters to 3.6 meters. Because the mowing platform is connected behind the tractor, when compounding, except the middle The connection adopts rigid pin connection, and other auxiliary connections adopt steel wire soft connection. The mowing platform of this kind of connection needs to reach a certain weight to ensure the stability of the whole mowing platform during mowing, and the adjustment of the mowing height needs to be manually adjusted; at the same time, from the tractor The power shaft coming out is directly connected to the gearbox, which also makes it very troublesome...
