Problems solved by technology

Foreign automatic guide devices mostly use ridges or furrows as the reference for guidance, and are not suitable for upright straw environments
In addition, there is another automatic guiding device for vegetable crops, which uses two symmetrical straight rods fixed on both sides of the angle sensor, and detects by contacting the rotation of the crops, but the range of rotation angle changes is small, and it is only suitable for auxiliary guidance when the driver is driving in the opposite direction.

Embodiment Construction

[0013] As shown in Figure 1, 1 is the contact rod, 2 is the connecting plate, 3 is the rotating shaft, 4 is the bearing, 5 is the angular displacement sensor, 6 is the cantilever beam, 7 is the strut, 8 is the centering spring, and 9 is the centering pole. The contact rod 1 of the present invention is a symmetrical arc. In this embodiment, it is semi-elliptical and connected to both ends of the connecting plate 2. The center of the connecting plate 2 is connected to the vertical rotating shaft 3 through a bushing. The rotating shaft 3 is located in a symmetrical arc. On one side of the center of the circle, the contact rod 1, the connecting plate 2 and the rotating shaft 3 are connected as one, and can rotate simultaneously. The upper part of the rotating shaft 3 is connected with the cantilever beam 6 through the bearing 4, so that the two can rotate relative to each other. The rotating shaft is provided with a thread of 30 cm, which can adjust the height of the contact rod p...

Abstract

A stalk guiding and detecting mechanism of tractor for working between two lines of stalk in corn, sorghum, or cotton field is composed of a cantilever, a contact rod unit consisting of connected symmetrical two arc contact rods with rotary axle, and an angular displacement sensor with rotary axle linked with said rotary axle of contact rod unit.

Description

technical field [0001] The invention relates to an automatic guiding detection device for agricultural power machinery operating between rows of corn (sorghum, cotton) stalks, belonging to the field of agricultural machinery. Background technique [0002] Conservation tillage cancels plowing operations, covers the surface with a large amount of straw and stubble, and directly sows without tillage. It can conserve water, moisture, and fertilize the soil. It has been widely promoted in the one-cropping area in northern my country. Conservation tillage is an effective way to increase yield, reduce cost, and save water and energy in areas where winter wheat and summer corn are harvested twice a year in North China. However, due to the thick corn stalks and thick root stubble that are not easy to cut off, problems such as machine blockage and ditching shovel deformation often occur when sowing wheat after corn harvesting, which seriously affects the quality of sowing, reduces pro...
