Description
Technical field
The utility model belongs to agricultural mechanical field, is related to a kind of sugar-cane cutting machine, more particularly to a kind of sugar-cane cutting machine
Wind removing machine speed control mechanism.
Background technology
At present, the harvesting sugarcane mode in China is manually cut down by the way of most original, filled still mainly based on artificial
Fortune, whole process labor intensity is big, operating efficiency is low.With the fast development of China's economy in recent years, hand labor cost is not
It is disconnected to improve so that sugarcane industrial profit continuous decrease, to cause sugarcane acreage to reduce year by year.Therefore, harvesting sugarcane mode by
Excessively it has been manually imperative to professed machine.In recent years, some domestic enterprises attempt to develop a variety of sugar-cane cutting machines, but all
The especially control of sugar-cane cutting machine wind removing machine speed, it is therein ask because technical a variety of causes is difficult to be promoted
One of topic.
At present, sugar-cane cutting machine wind removing machine speed control method can be made substantially there are three kinds in the prior art：One, enter
Oil-out speed governing, although this mode of speed regulation speed adjustable range is wide, caloric value is big, and operating efficiency is low；Secondly, pass through variable pump
Speed control is realized with variable displacement motor, although this mode of speed regulation speed adjustable range is wide, caloric value is small, and operating efficiency is high, warp
Cost of helping is higher, complicated；Thirdly, use ratio valve speed governing, although the control of this mode of speed regulation is simple, financial cost
It is higher.
For these reasons, we have developed a kind of sugar-cane cutting machine wind removing machine speed control mechanism, verification experimental verification, this
Kind mechanism also causes wind removing machine in the process of running on the premise of sugar-cane cutting machine wind removing machine speed control is met, hair
Heat is moderate, efficiency high, compact-sized, stable, cost-effective.
Utility model content
The purpose of this utility model is to provide a kind of compact, stable, the high sugar-cane cutting machine removal of impurities wind of reliability
Machine speed control mechanism.
The utility model reaches above-mentioned purpose using following technical scheme：Sugar-cane cutting machine wind removing machine speed control machine
Structure, including, wind removing machine, hydraulic motor, choke valve, hood；Wind removing machine top is provided with hydraulic motor, and hood, which is covered in, to be removed
On miscellaneous blower fan and hydraulic motor, hydraulic motor connects choke valve by pipeline, is set on the oil pipe that hydraulic motor is connected with choke valve
It is equipped with pressure oil port.
The first hydraulic pressure motor oil, the second hydraulic pressure motor oil are provided with hydraulic motor.
First throttle valve hydraulic fluid port, second throttle hydraulic fluid port are provided with choke valve.
Pressure oil port, first throttle valve hydraulic fluid port connect with the first hydraulic pressure motor oil.
Second hydraulic pressure motor oil connects with second throttle hydraulic fluid port and is connected oil return box respectively.
The utility model can reach following good effect after using above-mentioned technical proposal：Bypassed in the hydraulic fluid port of hydraulic motor
The easy configuration of one choke valve of upper connection, can make whole wind removing machine speed adjusting gear simple and compact, and cost is cheap, operation
It is stable, it is cost-effective.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model sugar-cane cutting machine wind removing machine speed control mechanism；
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.As shown in Figure 1：Sugar-cane cutting machine removes
Miscellaneous fan speed controlling organization, including, wind removing machine 1, hydraulic motor 2, choke valve 3, hood 4；Hydraulic motor 2 is arranged on and removed
The miscellaneous top of blower fan 1, hood 4 is covered in wind removing machine 1 and on hydraulic motor 2, two pipelines of hydraulic motor 2 are stretched out outside hood 4,
Wherein a pipeline is connected on choke valve 3.The first hydraulic pressure motor oil A2, the second hydraulic motor are provided with hydraulic motor 2
Hydraulic fluid port B2.First throttle valve hydraulic fluid port A1, second throttle hydraulic fluid port B1 are provided with choke valve 3.Pressure oil port P is led to by hydraulic pump
Cross reversal valve and pressure oil is provided.Pressure oil port P, first throttle valve hydraulic fluid port A1 and the first hydraulic pressure motor oil on hydraulic motor 2
A2 is connected.The second hydraulic pressure motor oil B2 on hydraulic motor 2 connects with the second throttle hydraulic fluid port B1 on choke valve 3, and second
Choke valve hydraulic fluid port B1 and the second hydraulic pressure motor oil B2 connect oil return box respectively.
During work, wind removing machine 1 drives rotation to produce wind-force by hydraulic motor 2, and control oil circuit is connected by hydraulic oil pipe,
The oil inlet P that hydraulic oil is set from choke valve 3 is sent, the first hydraulic pressure motor oil that connection enters on hydraulic motor 2 respectively
The second of A2 and choke valve 3 first throttle valve hydraulic fluid port A1, the second hydraulic pressure motor oil B2 and choke valve 3 on hydraulic motor 2
Choke valve hydraulic fluid port B1 connections hydraulic oil container forms the loop of hydraulic oil.When wind removing machine 1 needs big wind-force, choke valve 3 is screwed
The return flow formed at choke valve 3 is reduced, until no oil return, the full-load operation of wind removing machine 1；When wind removing machine 1 needs
When wanting less wind-force, choke valve 3 is unscrewed, by oil return allowance increase herein, is just reduced by the flow of hydraulic motor 2
, the wind-force of wind removing machine 1 is reduced by, so as to reach the purpose of sugar-cane cutting machine wind removing machine speed control.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to
The utility model full content, although the utility model is described in detail with reference to the foregoing embodiments, for this area
Technical staff for, it still can carry out formal modification to the technical scheme described in previous embodiment, or right
Which part technical characteristic carries out equivalent substitution.All made form modifications within thinking of the present utility model enlightenment, etc.
With replacement etc., should be included within rights protection scope of the present utility model.
