Subsoiler stress testing device

Abstract

The invention discloses a subsoiler stress testing device and belongs to the agricultural mechanical operation component detection technology. A screw rod provided with a handle is assembled on a slideway body seam. An upper nut and a lower nut are assembled on the screw rod. A frame seam is assembled on the slideway body seam in a vertically movable mode. The upper nut and the lower nut are fixedly connected with the frame seam respectively. Two upper connecting plates arranged opposite to each other and two lower connecting plates arranged opposite to each other are installed on a subsoiler assembly through hinges respectively. The subsoiler assembly is mounted on the frame seam in the mode that an upper pull-press sensor is connected with the frame seam and the hinge of the upper connecting plates and a lower pull-press sensor is connected with the frame seam and the hinge of the lower connecting plates. The subsoiler assembly is vertically positioned on the frame seam. A mounting plate is fixedly mounted on the side portion of the slideway body seam. When used for testing stress, the subsoiler stress testing device is easy, convenient and fast to adjust, accurate in height position, good in overall toughness, high in testing accuracy, low in operation cost, capable of being used repeatedly, and wide in application range.

Description

technical field [0001] The invention belongs to the detection technology of the working parts of agricultural machinery, and mainly relates to a device for testing the force of the working parts of the subsoiling shovel on the tillage equipment. Background technique [0002] The current method of measuring the force of the subsoiler shovel is mostly completed by pasting the strain gauges on the frame where the subsoiler shovel assembly is installed. The strain gauges can no longer be used, and the test cost increases, especially when the working depth of the subsoiling shovel assembly needs to be adjusted to measure the different stress conditions of the subsoiling shovel assembly, the position of the fixed fitting point of the subsoiling shovel assembly on the frame must be changed. Only then can the subsoiling shovel assembly be displaced up and down on the frame, which is not only inconvenient, laborious and inefficient to adjust, but also has a small depth adjustment ran...
