Abstract

The invention relates to a salt-raking mechanism which carries out farm work on salt bed, can carry out full stubble on the salt bed and crushes salt surface layer. Its work principle is as follows: output power of a gearbox of the farm work machine is transmitted through an universal shaft coupling to a decelerator fixed on a rake body of the farm work machine and then is transmitted to a main shaft of the rake body. The main shaft is provided with a driving wheel which is respectively engaged with two driven gears. Each driven gear is connected with a crank through an eccentric shaft. Each crank is connected with a connecting rod, which is connected with a row of rake. Simultaneously, in order to prevent from destroying a salt pan base plate, rake teeth are made into a hook shape. The design of the invention has the following advantages and positive effects: the farm work rake can reciprocate from side to side and swing while moving forward with the farm work machine, so as to drive the rake to carry out stubble operation on the salt bed. The swing frequency can be adjusted by the gearbox of the farm work machine, so as to fully and uniformly carry out the stubble operation with high efficiency. In addition, the rake body can be folded such that the farm work machine is convenient to operate outside the salt pan.

Description

The special-purpose farm work rake of salt pan farm work machine

Technical field

The present invention relates to a kind of rake salt mechanism that salt deposit is implemented the farm work operation in the salt pan, especially can make salt deposit carry out abundant farm work, broken salt top layer makes farm work more abundant, helps the crystalline growth of salt more, and then improves the quality and the output of salt.

Background technology

Existing salt pan farm work machine is harrowed fixed connection behind the salt machine with farm work; Drag the purpose that rake work reaches farm work to overtake through the farm work machine; The rake body is motionless, and the farm work operation effectiveness is undesirable, and need repeat work back and forth; Not only time-consuming consumption power, efficient are low, have also increased salt pan operating personnel's labour intensity.And the rake body is very long, the inconvenience of outside the salt pan, going.

Summary of the invention

The technical issues that need to address of the present invention are: overcome disadvantages of background technology, a kind of compact construction, reasonable is provided, the farm work mechanism that efficient is high; Adopt double rake body, during the farm work operation, harrow between the body perpendicular to farm work machine heading; Reciprocally swinging in opposite directions, amplitude of fluctuation can be regulated.The rake body can fold when not working, and has reduced the space, is convenient to outside the salt pan, go.

The technical scheme that the present invention adopted is: the back power output of farm work machine gearbox passes to the speed reduction unit on the farm work rake body through universal coupling; After the raising torque of slowing down, pass to the main shaft of rake body; A motion-work wheel is housed on the main shaft, and motion-work wheel meshes with two follower gears respectively.Each follower gear connects with crank through excentric shaft, and crank is connecting connecting rod, and connecting rod is connecting row's rake again, and two rolling bearing supportings are leaned at the two ends of rake, and rake body two ends can be folding to the centre when not operation.In order to prevent to destroy the salt pan base plate, the rake tooth becomes hook-shaped.Work of the present invention is, about the farm work rake self can be realized in the forward movement of farm work machine in opposite directions to-and-fro movement form swing, and then drive rake salt deposit carried out the farm work operation, its hunting frequency can be regulated by the farm work machine gearbox and realized.Rake body self has folder function, is convenient to outside the salt pan, exercise.

Embodiment

When outputting power behind the farm work machine gearbox passes to main shaft (1); Main shaft (1) drives motion-work wheel (2) and rotates; Motion-work wheel (2) drives follow-up pulley 1 (3) and follow-up pulley 2 (4) rotates; These two follow-up pulleys drive crank 1 (7) and cranks 2 (8) through excentric shaft 1 (5) and excentric shaft 2 (6) respectively, and these two cranks are driving the upward formation left and right sides to-and-fro movement of rolling bearing (11) at vehicle frame of the rake (10) that connects through connecting rod (9) separately respectively, finally reach the purpose of realization salt pan farm work operation.

Claims

1. the special-purpose farm work rake of a salt pan farm work machine mechanism is made up of main shaft, motion-work wheel, follow-up pulley, excentric shaft, crank, connecting rod, rake body and vehicle frame etc.It is characterized in that: the motion-work wheel on the main shaft is given the follow-up pulley that meshes with it transmission of power, passes to excentric shaft, crank and the connecting rod that connects with it to power respectively through follow-up pulley, finally is delivered to the bamboo rake body that connects firmly with connecting rod.Make two rakes can do reciprocal move toward one another simultaneously respectively, and the tooth of rake processes hook-shapedly, make the salt deposit farm work fully, evenly.

2. the special-purpose farm work rake of farm work machine according to claim 1, it is characterized in that: power passes to the rake body through universal coupling, and rake has double formation, can realize back and forth swinging in opposite directions, and amplitude of fluctuation and frequency can be regulated.

3. the special-purpose farm work rake of farm work machine according to claim 1, it is characterized in that: the two ends of rake mechanism have folder function, open during operation in the salt pan; Collapsible when not working outside the salt pan, reduced the space, be convenient to outside the salt pan, go.

4. the special-purpose farm work rake of farm work machine according to claim 1, it is characterized in that: the rake tooth is processed hook-shaped, has prevented that the salt pan base plate is not destroyed.
