Vibratory potato harvester

Abstract

The invention discloses a vibratory potato harvester, comprising a frame, a traction rack and traveling wheels, and also comprising a vibratory separating screen, a digging blade, a support, a vibrating rack, and a cam mechanism, wherein the vibrating rack drives the vibratory separating screen and the digging blade to move so as to provide a digging function and a separating function. The vibratory potato harvester is small in size, light in weight and simple in structure, and therefore the manufacture cost is low; the vibratory potato harvester has high potato digging efficiency, and can bedriven with a miniature tractor to well harvest potato; therefore, harvesting efficiency is greatly improved, the consumption of manpower and material resources can be decreased, time consumption canalso be decreased, and the production requirements of families and small enterprises can be met, wherein the requirements refer to the advantages that, for instance, the potato harvester operates stably and is simple to operate and low in cost, high digging efficiency is guaranteed, potato integrity is high, and fruit-soil separation is effective.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a vibrating potato harvester. Background technique [0002] The nutritional value of potatoes is very high, and the market potential is huge. In foreign countries, about 40% of potatoes enter the consumer market after being processed into food. Dr. Qu Dongyu, vice president of the Chinese Academy of Agricultural Sciences, pointed out at the China Potato Academic Annual Conference held recently: "Potato is a crop with high yield, strong adaptability and high economic value. The main potato production areas should be included in the national grain commodity grain. Bases enjoy the same financial and tax treatment as rice, wheat and other commodity grain bases, which will be an effective means to ensure food security in our country. Potato harvesters are indispensable equipment for contemporary potato harvests. [0003] The research on potato harvesters in our country started ...

AI Technical Summary

Problems solved by technology

[0003] The research on potato harvesters in our country started late and developed slowly. Compared with developed countries, it can only be compared with developed countries. Some of the popular machines in the market currently have the following problems. Therefore, it is difficult to popularize and apply them on a large scale

[0004] 1) Low mining efficiency

During some field operations, the potatoes were not fully dug, and many fruits were still in the soil layer, and the machine entered the soil shallowly.

Therefore, low digging efficiency is the biggest obstacle to popularize the use of potato harvesters.

[0005] 2) High loss rate

Due to the unreasonable selection of parameters during the design, the phenomenon of incomplete excavation is relatively serious. The fruits are in many large clods, which cannot be directly presented to people, and need to be harvested twice.

[0006] 3) The integrity of the nuts is poor

Harvesting machines designed by some manufacturers, in order to improve the phenomenon of missing peeling or incomplete excavation in the field, blindly pursue the improvement of excavation rate, causing many fruits to be broken, thereby reducing the commodity value of the product

[0007] 4) The performance of the machine tool is unstable and the adaptability is not high

When the soil moisture content, hardness, fruit shape, size, variety and other factors change, the performance of the special-purpose potato harvester specially developed for certain types of potatoes will also become unsatisfactory.

[0008] There are many potato harvesting devices currently on the market, but most of the large machines are more suitable for small-area household scenarios, while small potato harvesting devices have low digging efficiency and are time-consuming and laborious.

Because the traditional potato harvesting equipment cannot dig and harvest efficiently, it requires a lot of manpower to harvest, and the land after work is lumpy, and the picking of potatoes requires crushing the soil for harvesting
