Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a root digging mechanism for agricultural machinery. Background Art

[0002] The root digging mechanism for agricultural machinery is a mechanical equipment used to dig the roots of crops. It is mainly used to dig crops with roots, replace manual work, reduce labor intensity and improve efficiency. Taking radish as an example, in the actual harvesting process, radish is mostly harvested manually. Since the radish plant includes tubers in the soil and radish leaves extending out of the soil, if the soil is relatively soft, the radish leaves can be directly pulled out manually, which can also facilitate the collection of radishes. However, if the soil is relatively compacted, it is generally necessary to use a shearing device to cut the radish leaves, and then use shovels and other equipment to dig them out. The above manual operation method is not only inefficient, but also very easy to shovel off the radish tuber or scratch the surface of the radish tuber, thus having a greater impact on the long-term preservation of radish.

[0003] The existing patent discloses a root digging mechanism for agricultural machinery (CN108353609A), which includes a mobile frame connected to a traction mechanism, and a leaf cutting mechanism, a root digging mechanism and a material collecting mechanism are arranged at the front and rear ends of the length direction of the mobile frame respectively. The root digging mechanism includes two soil-opening plates, and the two soil-opening plates are arranged obliquely at the front and rear ends of the length direction of the mobile frame. The front ends of the two soil-opening plates are high and the rear ends are low. The two soil-opening plates are arranged in an "eight" shape and are located at the front end of the mobile frame as the large-spacing end. The feeding end of the material collecting mechanism is arranged below the rear ends of the two soil-opening plates, and the discharging end of the material collecting mechanism is connected to the feeding port of the silo. The above-mentioned two soil-opening plates are in an "eight" shape, can be probed into the ground, and turn over the soil along the side of the radish tuber, thereby avoiding damage to the radish tuber.

[0004] The device uses two figure-eight-shaped soil-opening plates to turn over the soil and take out the radishes, but this device has many operating steps, a slow digging speed, and low efficiency. Summary of the invention
