Abstract
The utility model discloses a kind of novel corn threshing cylinder, including cylinder, the spike-tooth being arranged on the cylinder, angle is less than 90 ° between spike-tooth and cylinder the fixing point tangent line.The utility model is adjusted the orientation that spike-tooth is connected with roller, is changed into present spike-tooth with roller at an angle from vertical welding before, the opposite direction of angle deflection roller rotation.Simultaneously, spike-tooth is also changed to adjustable for height threaded connection sprig tooth by the utility model, the advantages of this structure type is spike-tooth height adjustable, when spike-tooth excessive height, gap between spike-tooth and notch board reduces, and then the high phenomenon of corn kernel percentage of damage occurs, and when spike-tooth is highly too low, gap between spike-tooth and notch board is excessive, so as to the incomplete phenomenon of corn kernel threshing occur, seed can not depart from from corn ear completely, threshing of two kinds of situations to corn has harmful effect, the utility model uses the spike-tooth of adjustment height, optimal spike-tooth height when therefore can be found a job by adjustment.
Description
Technical field
It the utility model is related to agricultural machinery, and in particular to a kind of novel corn threshing cylinder.
Background technology
In the last few years, the development of agricultural machinery was all obvious to all, and various new agricultural equipments endlessly gush
Reveal and, the appearance of these mechanized equipments is brought great convenience to peasant, and peasant is solved to releasing from onerous toil
Come, the dream of mechanization of agriculture is more and more nearer from us, the appearance of corn kernel reaper, for peasant save the plenty of time and
Energy, by ear of maize of breaking before, peeling and grain harvest are combined together, and realization is once gathered in, convenient and swift.Corn cylinder
Design be corn picker important step, corn ear obtains seed by broken apart in roller, realizes harvest purpose,
But the design of spike-tooth structure and position is not perfect enough in current threshing cylinder, easily there is corn kernel percentage of damage height and threshing
Incomplete phenomenon, carry out no small loss to peasant's friend took.
The connected mode of spike-tooth and roller is is vertically welded on roller in the prior art, after this structure design is caused
Fruit is that spike-tooth and spike-tooth stress during corn contact are less desirable, is positive direct collision when spike-tooth is in contact with corn ear, right
The impulsive force of spike-tooth and corn ear is very big, easily causes destruction.
The content of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of novel corn threshing cylinder.
The technical solution of the utility model is：A kind of novel corn threshing cylinder, including cylinder, are arranged on the cylinder
Spike-tooth, angle is less than 90 ° between spike-tooth and cylinder the fixing point tangent line.
Further improvement of the utility model includes：
The spike-tooth is flexibly connected with the cylinder.
The spike-tooth is fixed by the spike-tooth backplate being arranged on the roller, and is between the spike-tooth and spike-tooth backplate
Threaded connection.
The spike-tooth and cylinder at an angle, the opposite direction of angle deflection cylinder rotation.
The utility model is adjusted the orientation that spike-tooth is connected with roller, is changed into present from vertical welding before
Spike-tooth and roller at an angle, the opposite direction of angle deflection roller rotation.Meanwhile spike-tooth is also changed to height by the utility model
Adjustable threaded connection sprig tooth, be spike-tooth height adjustable the advantages of this structure type, when spike-tooth excessive height, spike-tooth and
Gap between notch board reduces, and then the high phenomenon of corn kernel percentage of damage occurs, and when spike-tooth is highly too low, spike-tooth with
Gap between notch board is excessive, and so as to the incomplete phenomenon of corn kernel threshing occur, seed can not take off completely from corn ear
From threshing of two kinds of situations to corn has harmful effect, and the utility model uses the spike-tooth of adjustment height, therefore can pass through
Optimal spike-tooth height when adjustment finds a job.
By it was verified that the high phenomenon low with threshing performance of seed damage rate has when the utility model is for harvest corn
Good improvement result, positive effect.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1st, cylinder, 2, spike-tooth, 3, spike-tooth backplate, 4, nut.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of novel corn threshing cylinder of the utility model, including cylinder, it is arranged on the cylinder
Spike-tooth, angle is less than 90 ° between spike-tooth and cylinder the fixing point tangent line.
The spike-tooth is flexibly connected with the cylinder.The spike-tooth is consolidated by the spike-tooth backplate being arranged on the roller
It is fixed, and be to be threadedly coupled between the spike-tooth and spike-tooth backplate.With cylinder at an angle, angle deflection cylinder revolves the spike-tooth
The opposite direction turned.
The utility model is adjusted the orientation that spike-tooth is connected with roller, is changed into present from vertical welding before
Spike-tooth and roller at an angle, the opposite direction of angle deflection roller rotation.Meanwhile spike-tooth is also changed to height by the utility model
Adjustable threaded connection sprig tooth, be spike-tooth height adjustable the advantages of this structure type, when spike-tooth excessive height, spike-tooth and
Gap between notch board reduces, and then the high phenomenon of corn kernel percentage of damage occurs, and when spike-tooth is highly too low, spike-tooth with
Gap between notch board is excessive, and so as to the incomplete phenomenon of corn kernel threshing occur, seed can not take off completely from corn ear
From threshing of two kinds of situations to corn has harmful effect, and the utility model uses the spike-tooth of adjustment height, therefore can pass through
Optimal spike-tooth height when adjustment finds a job.
By it was verified that the high phenomenon low with threshing performance of seed damage rate has when the utility model is for harvest corn
Good improvement result, positive effect.
The utility model has installed the structures such as spike-tooth backplate, bolt, nut additional, and the design of spike-tooth structure is compared with before
There are some changes, spike-tooth structure has been designed to contain female form, and the form being connected through a screw thread replaces Type of Welding real
The connection of existing spike-tooth and roller, the purpose for making such a change is to realize the controllability of spike-tooth height.
Spike-tooth backplate is one section of support with certain angle formed by bending steel plate itself, and he is welded on into roller
On, while bolt is passed through from the bottom up and is weldingly fixed on spike-tooth backplate, spike-tooth and nut driving are entered after bolt i.e.
Achievable spike-tooth is fixedly connected with roller, due to the presence of the nail thorn backplate gradient itself, after spike-tooth fixes, meeting and roller
An angle is produced, so as to realize the purpose of spike-tooth snub pulley rotation opposite direction.
It can realize that the adjustment of spike-tooth height converts by screwing for screw thread, while in the root of bolt, pass through and install additional
Two nuts position to spike-tooth, position set after by the smearing of anaerobic adhesive, realize the fixation to spike-tooth.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
