Staged packaging type potato combine harvester

Abstract

The invention relates to a staged packaging type potato combine harvester. The harvester comprises a rack (13); a roll shaft chain type staging device (35), a first stage soil and potato separation and conveying device (34) and a second stage soil and potato separation and conveying device (12) are arranged on the rack (13); ground wheels (11) are arranged at the lower part of the rack (13); a belt scraper type lifting elevator (16) is arranged on one side; a material receiving and packaging device (22) is arranged on the roll shaft chain type staging device (35); a transverse chain rod type conveyor (17) is arranged at the back end of the second stage soil and potato separation and conveying device (12); an elastic stripper rod pick-roll type two-stage stalk separation device and rubber belt type two-stage stalk separation device are further arranged between the first stage soil and potato separation and conveying device (34) and the second stage soil and potato separation and conveying device (12); a digging shovel frame (3) and the rack (13) are articulated through a traction rod (31); a copying soil breaking roll (1), a soil cutting disk (2), a digging shovel (32) and a soil loosening transition tooth (4) are arranged on the digging shovel frame (3); and the upper part of the digging shovel frame (3) is connected with a lifting rod of a lifting cylinder (29). The harvester is in tractor traction type and can complete the procedures of digging of potato crops, soil and potato separation, separation of stalk, weeds and a ground film, conveying and lifting of potatoes, staging of potatoes, collection, packaging and the like of potato crops.

Description

Technical field: [0001] The invention relates to the technical field of equipment capable of one-time joint harvesting of potatoes, in particular to a graded bagged potato combine harvester. Background technique: [0002] At present, there are many types of potato harvesting equipment at home and abroad. For example, there are basically two types of potato harvesters: one is a small and medium-sized potato excavator, which has a single function. It can only excavate, separate, and lay potatoes on the ground in strips. Manual picking, manual grading when necessary, labor and time-consuming, low production efficiency, labor intensity is still relatively high. One is a large and medium-sized potato combine harvester, which also has a self-storage type and a side-arm output type. The side-arm output type is more commonly used. It is bulky and has a large supporting power. 1. Difficult field operations are suitable for large-scale operations. At present, there are patent reports...

[0002] At present, there are many types of potato harvesting equipment at home and abroad. For example, there are basically two types of potato harvesters: one is a small and medium-sized potato excavator, which has a single function. It can only excavate, separate, and lay potatoes on the ground in strips. Manual picking, manual grading if necessary, labor and time-consuming, low production efficiency, labor intensity is still high

One is a large and medium-sized potato combine harvester, which also has a self-storage type and a side-arm output type. The side-arm output type is more commonly used. It has a large volume and a large supporting power. , Field operations are difficult, suitable for large-scale operations, and currently suitable for medium-sized plots. The potato combine harvester that can simultaneously achieve grading has patent reports, but has not been put into production.
