[0002] At present, cassava harvesting in most areas of our country still adopts the method of manual harvesting, using simple agricultural tools to harvest cassava, which has high labor intensity, low production efficiency and high operating cost, which greatly affects the development of cassava industry
In recent years, a pull-up mechanical device has also been used for cassava harvesting. However, due to the large weight and volume of the harvesting machinery dragged by tractors, it is not suitable for the complex terrain and small fields in hilly and mountainous areas. Without the function of shaking up and down, it is easy to cause damage to the roots and a high rate of broken potatoes
So far, there is no cassava harvesting machine in the domestic and foreign markets that can adapt to mountains and small plots, has a shaking function, has high production efficiency, and is low in price and light.

Abstract
The invention relates to an agricultural machine for harvesting cassava and provides a small shaking type cassava harvester. The small shaking type cassava harvester is composed of a quick-shaking type hydraulic jack, a large plunger rod, a small piston rod, a reversing valve or a stop valve, a frame, a main beam, a rear beam, stand columns, a stand column middle beam, a lifting frame, a chain wheel, a chain, rolling wheels, a suspension arm, a flexible piece, an operation rod, a quick stem clamp, wheels, supporting legs and the like. The reversing valve or the stop valve is used, the shaking and non-shaking functions of the large plunger rod, the suspension arm and the quick stem clamp can be achieved by pressing down or lifting up the operation rod, and thus cassava can be vertically shaken and pulled up in the pulling process. The small shaking type cassava harvester is capable of saving labor, small in cassava breakage rate, high in productivity, convenient to operate, small, light, convenient to carry, firm, high in reliability, low in cost, capable of saving energy, environmentally friendly, low in use cost, capable of adapting to small mountainous field parcels, small rugged field parcels, farmland with complex terrain, farmland with other interplanted crops and wet and muddy farmland, capable of being used for pulling other plants and crops and wide in application.
Description
technical field [0001] The invention relates to a small-scale agricultural machine for harvesting cassava roots, in particular to a small shaking cassava harvester capable of effectively reducing the potato crushing rate, rapidly harvesting cassava roots, greatly reducing labor intensity, and adapting to mountainous areas. Background technique [0002] At present, cassava harvesting in most areas of my country still adopts the method of manual harvesting, using simple agricultural tools to harvest cassava, which is labor-intensive, low production efficiency, and high operating cost, which greatly affects the development of cassava industry. In recent years, a pull-up mechanical device has also been used for cassava harvesting. However, due to the large weight and volume of the harvesting machinery dragged by a tractor, it is not suitable for the complex terrain and small fields in hilly and mountainous areas.
