Self-propelled mechanical reciprocating soaked walnut harvester

Abstract

The invention discloses a self-propelled mechanical reciprocating juglans sigillata dode harvester which is composed of a power output mechanism, a supporting power lifting mechanism, a reciprocating motion switching device, a guide device and a clamping device. The self-propelled mechanical reciprocating juglans sigillata dode harvester is applicable to one-time harvest of juglans sigillata dode plants with the trunk diameter at breast height less than or equal to 320mm and fruit maturity not less than 80%; during harvest, the juglans sigillata dode trunks are fixed with the clamping device at the breast height position of the juglans sigillata dode trunks, the harvester is started, and harvesting of juglans sigillata dode fruits of one single plant with the diameter at breast height less than 320mm is completed at one time within 20 seconds; the harvest rate reaches above 98.7%, and harvesting efficiency is more than 90 times of that of artificial harvesting.

Description

technical field [0001] The invention belongs to the field of harvesting soaked walnuts, in particular to a self-propelled mechanical reciprocating soaked walnut harvester. Background technique [0002] pickled walnuts ( Juglans sigillata Dode) is a deciduous tree belonging to the family Juglandaceae. It is the largest economic forest fruit tree species in Yunnan Province with the largest planting area, the largest number of employees, and the most obvious increase in farmers' income. In 2014, the industrial base area reached more than 42 million mu, and the agricultural output value was nearly 30 billion yuan. . Bubble walnut is the walnut variety with the best quality recognized by the international academic circles and business circles; however, due to its low degree of mechanized production and high production costs, the export volume and sales volume are limited; and the labor force is becoming more and more scarce and the cost is getting higher and higher. Casualty ac...

Problems solved by technology

This picker has a simple structure and can meet the picking requirements of different positions and different walnut tree varieties. It has made a major breakthrough and perfection in the technology of the previous several disclosed pickers, but the disadvantages of this machine are: one, because The degree of fruit shedding is proportional to the reciprocating frequency and swing of the tree. The working principle of the machine is to use the reciprocating drive to transmit the power of the power device to the driving flat-bottom driven rod in the form of impact and then to the rubber block to realize the tree's impact. Vibration, that is, the force acting on the tree is only one-way force, without reciprocating force, it cannot form a large swing, it is difficult to make the fruit fall off in a short time and affect the picking effect; second, because the machine adopts single-point impact The tree vibrates so that the fruit falls off, and it is impossible to pick the fruit trees with a large DBH and crown at one time, and can only pick by branches, which prolongs the picking time and reduces the operating efficiency; third, because the machine adopts direct impact is With the help of the reaction force of the tree to vibrate the fruit tree, a fulcrum must be added. It is troublesome to choose the fulcrum rubber cushion when the diameter of the fruit tree is different.
