An electronic fruit sorting machine

Abstract

An electronic fruit sorter comprises a transmission mechanism, a hooper lifting device, a fruit arranging device and a control system, wherein the hopper lifting device is connected with the fruit arranging device, a primary sorting device and a fine sorting device in sequence, a sensing electronic scale is arranged on the primary sorting device, a fruit beating device and a fruit recycling device are oppositely arranged on two sides of the fine sorting device,a fruit plate correction device is arranged at the tail part of the fine sorting device, a cycling chain is arranged on the primary sorting device and the fine sorting device, the cycling chain is in transmission connection with a transmission mechanism with a variable-frequency governor, a fruit plate is arranged on the cycling chain, and the sensing electronic scale, the fruit beating device and the variable-frequency governor are all electrically connected with a control system. The electronic fruit sorter provided by the invention has the advantages that the structure is compact, the manufacturing cost is low, weighting and sorting accuracies are high, and the degree of automation is high; accurate screening can be performed; errors are fewer.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an electronic fruit sorting machine. Background technique [0002] At present, in order to increase the economic value of fruits, it is often necessary to weigh, sort and pack the fruits after they are harvested, and then sell them to the market. [0003] The existing fruit sorting machine is mainly based on mechanical weight sorting equipment. Its working principle is to place weights of different weights on the mechanical overturning device of the fruit tray. When the weight of the fruit reaches a certain weight range, the leverage principle is used. Relying on the fruit's own weight to press the tray to turn over to realize weighing and sorting. However, this mechanical weighing and sorting mechanism has the defects of complex structure, low weighing and sorting accuracy and automation, and high labor cost.

Problems solved by technology

Although this system can realize the automatic control of fruit weighing and sorting, the structure is complicated, the manufacturing cost is high, the accuracy of weighing and sorting and the degree of automation are not high, and the work efficiency is high.

[0005] Chinese patent 201220243231.1 discloses a fruit weight grade intelligent sorting machine, including a seat frame, which is provided with a number of trays that circulate in the same assembly line, and a conveyor belt is provided on the seat frame, and the fruit is transported on the conveyor belt. There is an electronic scale for weighing the fruit at the position of the tray. The electronic scale is set at the bottom of the tray, and there are multiple grading outlets on the frame. Several circularly rotating trays, conveyor belts and electronic scales form an assembly line working group. An electronic scale for weighing the weight of the fruit is provided at the position where the conveyor belt transports the fruit to the tray, and the electronic scale is set at the bottom of the tray to achieve instant weighing of the fruit when the fruit transported by the conveyor belt falls into the tray, and then according to The electronic scale weighs fruits with different weight grades and falls into different grading outlets to realize the classification of fruits in different weight grades. However, the structure is complicated and the manufacturing cost is high, and multiple electronic scales are required.
