Ground-contour-following circular disc elastic claw pickup

Abstract

The invention discloses a ground-contour-following circular disc elastic claw pickup for pickup operation of crop straws or pasture and relates to the technical field of straw harvesting and baling. The pickup mainly comprises a circular disc elastic claw roller, a suspended copying device and a floating grass pressing assembly. In the pickup operation of the pickup, the left and right copying wheels of the suspended copying device are in contact with the ground so that the integral pickup swings around a pipe shaft, and therefore, the pickup is suitable for ups and downs of the ground. Elastic claws in circling motion cooperate with the floating grass pressing assembly to form channels where picked materials flow so as to prevent the materials from being thrown out of the pickup and pick up the materials. According to the invention, a slideway of a conventional elastic claw pickup is cancelled; an elastic claw driving mechanism is simplified; and the main shaft of the pickup is allowed to have a relatively high rotating speed, so that the pickup operational efficiency of the crop straws or pasture is improved, and the pickup effect is good. Meanwhile, the ground copying circular disc elastic claw pickup disclosed by the invention is simple in structure, relatively convenient for batch production, low in manufacturing cost and convenient to use.

Description

technical field [0001] The invention relates to a disc type elastic tooth picker with ground profiling for picking up crop stalks or forage grass, especially a ground profiling disc spring tooth picker. Background technique [0002] The country can collect about 600 million tons of straw, and the comprehensive utilization of straw has formed. The market needs efficient and high-performance picking and bundling machines to meet the large-scale industrial application of straw. However, the pick-up of the existing pick-up and baler uses a reverse swing cam mechanism to drive the spring teeth to obtain the trajectory and posture required for picking up materials. The dynamic performance of the fixed slide cam is too high due to the deterioration of its dynamic performance, which is easy to cause parts Damaged, short service life, and the operating efficiency of the whole machine is limited by the pick-up device and cannot be improved. For this reason, the present invention adop...
