The potato harvester is a traction type machine, which is suitable for harvesting, separating, and automatically loading potatoes, garlic, sweet potatoes, peanuts and other underground root crops. The machine has the characteristics of high harvesting efficiency, low damage rate, light operation, no vibration, no grass blocking, fast soil leakage, simple structure and long service life. The machine adopts a side-by-side automatic loading device to make up for the shortage of small harvesters that can not automatically collect crops, improve production efficiency, save manpower and material resources, and is suitable for planting large areas of potatoes and other crops. The machine has obtained two patents for utility model and design approved by the National Patent Office.

Third, the scope of application
(1) Removal of cockroaches: chemical or mechanical killing of potato crops before harvest to ensure root height ≤ 150mm;
(2) Soil type: semi-sand or neutral soil with slightly corroded soil, no obstacles such as stones and roots in the soil;
(3) Soil moisture content: ≤10%;
(4) Potato planting spacing: 650-800mm
(5) Ground conditions: slope ≤ 40%, and the harvester has no side slip.
Fourth, the main structure and working principle
The 4UQL-160 potato harvester consists of a frame, digging shovel, working screen, gear box, drive shaft, traction hanger, suspension frame, depth limit wheel, rear tail wheel, rear lifting device and other components.
The tractor and the harvester are connected by the drive shaft and driven by the power output shaft of the tractor to drive the working screen. The digging shovel will shovel the crops to be harvested. The two sides of the disc cut the soil and the weeds. Excavate the shovel and fill the soil. The conveyor chain transports the potatoes backwards. The crops are transported to the rear by the rotation of the working sieve chain. In the device, during the transportation process, the vibration of the vibrating wheel of the universal is effective to separate the crop from the soil. The rear lifting device uses the side loading device to load the crop into the transport vehicle on the right side, saving manpower and material resources and improving production efficiency.
Five, maintenance and precautions
Regularly clean, inspect, lubricate, tighten, adjust or replace parts of the harvester, etc., in order to ensure that the harvester is always in good technical state, give full play to its effectiveness, and extend the use of the harvester. Life expectancy must be carefully carried out in accordance with the requirements of technical maintenance work. Technical maintenance of the harvester includes daily technical maintenance and annual technical maintenance. Daily technical maintenance is carried out every 8-10 hours of work; annual maintenance is carried out after the end of one working season.
