Abstract
The invention relates to a flue-cured tobacco stem pulling machine, which belongs to the technical field of machinery and solves the technical problems of unreasonable design and the like of the prior art. The stem pulling machine comprises a suspension machine frame, depth wheels and a break shovel, wherein the depth wheels and the break shovel are arranged on the lower portion of the suspension machine frame; drive sprockets, jockey sprockets, a clamping chain and a clamping pressing plate are arranged on the suspension machine frame; the ring-shaped clamping chain is sleeved between the drive sprockets and the jockey sprockets and respectively meshed with the drive sprockets and the jockey sprockets; the drive sprockets are connected with a motive power mechanism and driven to rotate by the motive power mechanism; the clamping pressing plate is positioned on one side of the clamping chain; a clamping channel for enabling tobacco stems to enter and be pulled up and outputted is formed between the clamping pressing plate and the clamping chain; one end of the clamping channel is a tobacco stem inlet positioned behind the break shovel, and the other end of the clamping channel is a tobacco stem outlet. The flue-cured tobacco stem pulling machine has the advantages that: 1 the break shovel loosens soil at the root portions of the tobacco stems, thereby being extremely labor-saving in pulling the stems. 2 the root portions carry a small amount of soil, thereby being favorable for cleaning the tobacco stems. 3 a lead-in port enables the tobacco stems to be smoothly conveyed into the clamping channel.
Description
Technical field
The invention belongs to field of mechanical technique, relate to agricultural tillage equipment, especially relate to a kind of flue-cured tobacco stem pulling machine.
Background technology
In the tobacco planting process, after tobacco leaf was plucked and finished, the tobacco rod that is retained between the field not only was difficult to rot, and can carry the tobacco pathogenic bacteria usually, therefore must as much as possible it be removed totally, was beneficial to follow-up cultivating, and realized the sustainable development of leaf tobacco production.At present, tobacco rod is extracted main dependence and is manually carried out, but because the tobacco root prosperity, pulling out mode need expend a large amount of labours and time by hand in employing, only is fit to the fritter field, and large-area field then can't be finished at all.
For this reason, people have carried out long-term exploration, have proposed various mechanical type scavenge units.The mechanical type scavenge unit mainly is divided three classes, i.e. cutting type, shovel and clamping drawing formula.The cutting type scavenge unit is to utilize cutting machine that stalk is cut off more than ground, and its shortcoming is that root system still stays in the soil, does not reach the purpose of removing fully.The shovel scavenge unit is to utilize shovel to cut parts with stalk root sliding trackle, and stalk is pulled out ground along the perching knife plane, enters soil because of perching knife is miter angle usually, and its shortcoming is that the stalk root often can only be cut half by shovel, and second half is then also stayed in the soil.Clamping drawing formula scavenge unit is that stalk is clamped and pulled up, and it is better that it removes effect, but normally through under any situation of loosening the soil tobacco rod is not being pulled up, and causes the tobacco rod fracture easily, and its root system still is retained in the soil; And because the stalk root system is comparatively flourishing, the energy consumption of equipment is also bigger during removing.In addition, the feeding performance of clamping drawing formula scavenge unit is relatively poor usually, and it is bigger influenced by stalk lodging degree, weeds etc.
In order to solve the problems of the technologies described above, people improve prior art.For example, Chinese patent literature discloses a kind of drawing bench of tobacco leaf [application number: 200910111776.X], it comprises transmission mechanism, pick pocket rotor, send bar rotor and rod-collecting box, the described bar rotor that send is between pick pocket rotor and rod-collecting box, described pick pocket rotor and send the bar rotor adjacent setting, and axially parallel, described transmission mechanism drive pick pocket rotor and send the bar rotor rotation, and described pick pocket rotor is provided with finger.This drawing bench of tobacco leaf can be disposable continuously with the tobacco rod turn up, clocklike stacks after it is collected, and thoroughly changes the existing manual labor type that pulls out or dig, and makes tobacco rod pull out the realization mechanized, improved labor productivity greatly.But the pick pocket rotor in the such scheme buries to operate by the finger intermittence and realizes excavating, and it is relatively poor that this structure exists mining ability, and finger buries more shallow, and finger is than technological deficiencies such as efforts.In addition, because finger is a gap distribution, causes Lou easily and dig.On the other hand, complicated integral structure, the manufacturing cost height still can be subjected to the influence of tobacco rod lodging.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of reasonable in design, simple in structure, the job stability height is easy to tobacco rod is pulled up, and the few flue-cured tobacco stem pulling machine of the tobacco rod root band that is pulled up soil amount.
For achieving the above object, the present invention has adopted following technical proposal: this flue-cured tobacco stem pulling machine, it is characterized in that, this pole jack comprises the suspension frame, and the gauge wheel and the break shovel that are arranged on the suspension frame lower, on the suspension frame, also be provided with drive sprocket, chain cable fairlead, clamping chain and clamping pressing plate, described clamping chain ringwise and be enclosed between drive sprocket and the chain cable fairlead and be meshed with drive sprocket and chain cable fairlead respectively, described drive sprocket and actuating unit link and this actuating unit can drive the drive sprocket rotation, described clamping pressing plate is positioned at a side of clamping chain and forms the clamping passage that tobacco rod is entered and it is pulled up and exports between the two, one end of described clamping passage is for going into the bar mouth, the other end is the rod mouth, describedly goes into the rear that the bar mouth is positioned at break shovel.
