Leakproof multi-purpose walking sweet potato vine crusher

Abstract

The invention relates to a leakproof multi-purpose walking sweet potato vine crusher, and belongs to the technical field of agricultural harvesters. A gearbox of the crusher is fixedly connected with an installation plate and an engine installation frame; the installation plate and the engine installation frame extend out forwards and backwards separately; the gearbox extends out of an operating rod towards the upper back part; the installation plate is connected with a vine cutting mechanism through a suspension frame; the vine cutting mechanism comprises knife rolls of cutting knives which are axially arranged at intervals and extend along the radial direction; a housing is arranged on each knife roll; tool aprons which are distributed along a helical line and extend out along the radial direction are axially distributed on a knife shaft of each knife roll at intervals; the tool aprons are hinged with the inner ends of the corresponding cutting knives; when the knife shafts rotate, tip rotating envelope surfaces of the cutting knives are matched with a ridge; a channel formed by intervals between the housings and the tip rotating envelope surfaces is in a necking form which is convergent from the front part to the middle part and is divergent from the middle part to the back part; and an inverted V splitter plate is arranged at the rear part of each housing. According to the leakproof multi-purpose walking sweet potato vine crusher, sweet potato vine leakage cutting can be effectively avoided, the cutting effect is improved and the condition that cut vines are thrown to furrows is ensured.

Description

technical field [0001] The invention relates to a device for crushing and returning potato seedlings and vines to the field, in particular to a leak-proof multi-purpose walking-type potato and vine crushing machine, which is suitable for crushing and returning seedlings and vines to the field before harvesting sweet potatoes and potatoes on hilly slopes and small fields. The utility model belongs to the technical field of agricultural harvesting machinery. Background technique [0002] Among the plants planted on high ridges such as sweet potato and potato with lush vines, sweet potato is a typical vine plant, whose vines usually grow to 1.5-7.0 meters, not only covering the entire ridge and the ground, but also intertwined and difficult to separate; potato Although the seedlings are upright and generally more than 0.5 meters in height, they are also prone to lodging during growth and interlaced with adjacent ridge potato seedlings. Therefore, before digging and harvesting ...

Problems solved by technology

[0005] However, through practice, the applicant realized that the above-mentioned "a walk-behind sweet potato shredded vine returning machine" still has the following disadvantages: 1) The potato vines along the ridge are very easy to miss cutting and remain, which is not conducive to harvesting operations; ) The broken vines that are directly thrown onto the ridge surface will easily cause the harvester to be entangled and affect the separation effect of potato and offal; 3) The one-piece fixed cover is closed inside, which is not convenient for the replacement of the cutter and the maintenance of the cutter shaft
