Description

{A electric rakes for salt field}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a salt-extinguishing product, and more particularly, to a salt-exclusively recycled salt product for pouring salt containing salt water generated in a salt-water partitioned by a dam into a dam while traveling.

In general, sun salt is produced in such a way that the salt contained in seawater is determined when seawater is trapped before the salt and when part of the seawater is evaporated by the sunlight. A method in which the operator pushes the pusher directly is used in a state where the salinity is determined at an appropriate level.

The problem is that the work is too hard, the worker consumes too much of the worker's power, and the work time is too long, which lowers the productivity.

In view of this, a device has been proposed in which a plunger is mounted on a moving means which is moved by a motorized method, and the plunger is pushed only by the electric power to remove the salt.

Although not shown in the drawings, the electric plungers of the prior art use only the power required for forward and backward movement of the plunger, but do not have a function of adjusting the gap between the plunger and the bottom face in the process of moving the plunger. As a result, depending on the surface condition of the bottom surface of the tidal zone, a part of the bottom surface of the tidal bar slips through the bottom of the tidal zone, thereby lowering the efficiency of collecting the salt.

In addition, since the plunger can move only in the straight direction, it is necessary to reciprocate the plunger several times in order to collect the leaking salt, which is scattered in the left and right direction of the plunger when the plunger is moved. .

In addition, the process of removing the salt in the salt trough pushes from the starting point to the opposite collection point, then backs to the starting point and repeats the process to the collection point again.

Therefore, when the position of the plunger is fixed, even when the plunger is returned from the collection point, the salt is pushed by the plunger, and when the plunger starts from the starting point to the collection point, the salt is accumulated in front of the plunger.

In other words, salt is unnecessarily removed during the process of returning to the starting point. When moving toward the collection point in this state, there is a problem that the lifetime is shortened due to a load on the driving motor due to a large amount of salt weight.

Patent Application No. 2014-0079969 discloses an electric plunger for salt.

The embodiments of the present disclosure relate to a salt-only motor vehicle that can increase the productivity of scraping the salt as the pushing force of the pusher against the bottom of the salt area is increased.

The embodiment of the present specification relates to a salt-exclusively used rubber product which minimizes the escape of salt to the left and right ends of the plunger when the plunger is moved in a straight direction,

The embodiments of the present disclosure relate to a slide-type motor vehicle, which is capable of traversing a bank of a torii zone or moving the auxiliary wheel at a certain height from the bottom of the torii zone when moving backward in a torii zone.

The embodiment of the present invention is characterized in that the pusher is provided with a motor-driven exclusive use for prevention of breakage of the plunger or the dam due to the turning of the plunger at the corners of the tumbling zone or the like, .

The salt-extinguishing rubber-like rubber according to the embodiment of the present invention

A drive wheel and a secondary wheel, a body on which a rechargeable battery is mounted;

A left and right handle mounted on the body for driving and controlling the driving wheel;

A first and a second actuator in which a head portion is rotatably mounted in front of the body and the rod portion is rotatably mounted on a back surface of the plunger by a bearing, Or angled to the right to travel;

And a control unit mounted on the left and right handles for controlling running of the plunger.

The present specification constituted as described above has the following advantages.

By increasing the pressing force of the plunger against the bottom surface of the tidal zone (that is, increasing the pushing force of the plunger against the bottom surface), even when the surface of the bottom surface is not smooth, the productivity of raking the salt is increased.

In addition, since the push rod can be rotated when the plunger is moved linearly to minimize the escape of the salt to the left and right ends of the plunger, it is unnecessary to reciprocate the plunger several times, thereby reducing the fatigue of the worker and increasing the productivity.

In addition, it is convenient and practicable to move across the bank of the salt zone or to move the auxiliary wheel (the castor) at an arbitrary height from the bottom surface of the salt zone when moving backward in the salt zone.

In addition, when the plunger changes its direction at the corners of the torn area, or moves close to the dam, the plunger blocks direct contact with the wood, etc. installed on the inner side of the trough to prevent breakage of the plunger or dam, And reduce the occurrence of post-management costs to repair.

And a control box 22 (control box) mounted on the left and right handles 16, 17 for controlling the running of the plunger 18. [

A guide roller 23 rotatably mounted on the left and right ends of the plunger 18 for blocking the plunger 18 from coming into direct contact with wood or the like provided on the inner side of the weir .

The auxiliary wheel 13

A pivot shaft 24 rotatably mounted to the rear of the body 15 in a clockwise or counterclockwise direction;

A supporter (25) rotatably mounted on the floor surface of the auxiliary wheel (13), and joined integrally to the rotary shaft (24);

A third electric actuator 27 rotatably connected to a leg 26 fixed to the rotary shaft 24 and having a head portion rotatably mounted on the body 15,

The auxiliary wheels 13 are lowered to be brought into contact with the tumbler bottom surface by turning the counter-clockwise rotation axis 24 of the electric three-actuator third actuator 27 in the counterclockwise direction, The auxiliary wheel 13 can be raised to the side of the body 15 by an arbitrary height from the bottom of the tread as the turning shaft 24 is rotated in the clockwise direction.

One end of which is fixed to the center shaft 28 and the other end of which is fixed to the body 15 and the other end of which is fixed to the body 15, A first elastic member 30 (which can be a tension coil spring can be used) fixed to a bracket 29 protruding forwardly is provided so that the elastic force of the first elastic member 30 when the plunger 18 travels, The pressing force of the plunger 18 against the bottom surface can be increased.

And a second elastic member 32 fixed to the upper portion of the intermediate side in the lengthwise direction of the back surface of the plunger 18 and the other end fixed to the bracket 31 protruded forward of the body 15, It is possible to prevent the plunger 18 from being tilted in the running direction due to the elastic force of the second elastic member 32 (the tension coil spring can be used) when the vehicle travels.

Hereinafter, an example of using a salt-extinguishing exclusive use salt according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7, the electric actuators 10 and 11 are driven by the battery 14 mounted on the body 15, and the electric actuators 10 and 11 drive the drive wheels 12 And the body 15 is supported by the auxiliary wheel 13 (caster), which is rotatable at the time of traveling, by turning the plunger 18 to the straight run, the left turn or the right turn by the operation of the left and right handles 16, The detailed description of the configuration thereof will be omitted.

When the left and right handles 16 and 17 are operated, the first and second electric actuators 20 and 21 are driven to rotate the push rod 18 in the pushing direction, The first and second electric actuators 20 and 21 are driven to change the angular position of the plunger 18 by changing the angular position of the plunger 18 in a leftward tilted state or operating the left and right handles 16 and 17, The vehicle can be driven while being angularly changed to a tilted state in the rightward direction.

That is, the salt generated on the bottom surface of the salt zone includes part of the salt water, so that when the salt is scraped up in the running direction while moving the plunger 18 linearly, part of the salt along the salt water is directed to the left or right side . As a result, in order to collect some of the salt that has escaped from the plunger 18, the sampling area is moved repeatedly.

As shown in Figs. 2 (a) and 2 (b), when the first and second electric actuators 20 and 21 are driven, the plunger 18 is angularly changed to be inclined at an arbitrary angle in the left direction, The vehicle can be driven while being angularly changed so as to be inclined at an arbitrary angle in the rightward direction.

When the plunger 18 is tilted in the left or right direction and then traveled, the brine in the bottom of the tundish zone is moved in an inclined direction of the plunger 18.

Thus, most of the salt on the bottom surface is raked in the running direction of the plunger 18, and some of the salt moves along the salt water in the inclined direction of the plunger 18. The salt moved in the inclined direction of the plunger 18 can be collected by moving the plunger 18 the next time. It is possible to prevent the salt from escaping in an inclined opposite direction of the plunger 18.

As described above, when the bottom 18 is scraped off while the bottom 18 is moved along the bottom surface of the tumbling zone, the guide rollers 23 are rotatably mounted on the left and right ends of the tumb 18 It is possible to prevent the plunger 18 from being in direct contact with the inner surface of the dam.

As a result, it is possible to prevent the dam 18 or the bar 18 made of wood or the like from being damaged due to an impact generated when the bar 18 turns at a corner or the like of the salt zone, or when the bar 18 comes into direct contact with the dam, do.

On the other hand, in the course of collecting salt in the salt zone, the auxiliary wheel (13) is moved from the bottom surface of the salt zone by driving the electric third actuator (27) at the time of traversing the dam to move to the adjacent salt zone, It can be spaced at an arbitrary height.

More specifically, as shown in FIG. 5, when the reverse button provided in the control unit 22 is operated, the electric third actuator 27 is driven to extend. The extension drive of the third actuator 27 causes the rotary shaft 24, which is rotatably connected to the rod end via the legs 26, to rotate clockwise. The auxiliary wheel 13 is raised to the side of the body 15 by an arbitrary height from the bottom surface of the torsion bar due to the rotation of the pivot shaft 24.

Therefore, since the auxiliary wheels 13 are raised to a certain height from the bottom surface, the dam (generally formed at a height of 200 to 300 mm) can be easily moved And it is possible to prevent scratching of the bottom surface of the torsion zone when the plunger 18 moves backward.

On the other hand, when the auxiliary wheel 13, which is upwardly adjusted toward the body 15, is brought into contact with the bottom surface of the torsion zone, the rotary shaft 24 is rotated in the counterclockwise direction by retracting the electric third actuator 27 do. As a result, the auxiliary wheel 13 fixed to the rotary shaft 24 through the supporter 25 can be lowered to be brought into contact with the tumbler bottom surface.
