It is needless to say that the components shown in FIG. 1 are not essential, so that the salt sprayer 100 having more or fewer components can be implemented. Hereinafter, each component will be described.

The hopper 110 is a container for temporarily storing the salt introduced from the outside, and can have a funnel shape that is turned upside down. The salt introduced into the hopper inlet formed at the upper portion of the hopper is discharged to the hopper outlet formed at the lower portion of the hopper and the inlet of the hopper has a diameter larger than the outlet of the hopper so that the salt introduced into the upper portion of the hopper can be temporarily stored therein before being discharged to the hopper outlet.

[

The belt of the conveyor 120 can be supported by the conveyor pulley 122 and the conveyor guide roller 123 so as to be able to rotate while being tightened by a tension greater than a predetermined size. The conveyor belt caught by the conveyor pulley 122 and the conveyor guide rollers 123 is conveyed to the conveyor pulley 122 through the conveyor drive chain 124 by the driving force generated by the conveyor drive device 125, And is rotated by the rotation of the conveyor pulley 122.

Here, it is preferable that the conveyor pulley 122 for rotating the belt of the conveyor 120 is located on the side opposite to the side of the hopper 110, that is, on the side where the salt is sprayed. This is because the driving method of the conveyor for conveying the salt is adopted as the front wheel type, so that the loss of the conveyor driving force can be relatively reduced as compared with the case of using the rear wheel method.

The conveyor drive device 125 that provides the driving force to rotate the conveyor pulley 122 is preferably located at the other end of the conveyor 120, i.e., opposite the hopper 110, and the conveyor drive device 125 The driving device support portion 126 may be erected on the other end of the conveyor frame 121 supporting the conveyor 120 so that the conveyor 120 can be seated.

[ The conveyor frame 121, which is rotatable around the frame rotation shaft 142, can be adjusted to have a predetermined angle with the ground surface, thereby adjusting the spraying distance or the spraying range of the salt.

The other end of the conveyor 120, that is, the front end of the salt spraying apparatus 100, is provided with a rotating body 132 for scattering the salt transferred by the conveyor 120.

At this time, the rotating body 132 is positioned in front of the conveyor 120 so that the salt transferred by the conveyor 120 falls into a gap formed between the conveyor 120 and the rotating body 132, The rotating body 132 is disposed at a front lower portion of the conveyor 120 and the end of the conveyor 120 and the blades of the rotating body 132 are arranged to overlap a predetermined portion, It is preferable to spray the dropped salt from the end portion of the water tank to the front.

Here, a detailed description of the rotating body 132 will be described later.

The salt spraying apparatus 100 may further include a rotating body driving apparatus 131 for generating a driving force for driving the rotating body 132 and a driving force generating unit 132 for applying driving force generated by the rotating body driving apparatus 131 to the rotating body 132, And a rotating body driving belt 133 for transmitting the rotating body driving force.

The first wings 1322a and 1322b are coupled to the inside of the wing receptors 1321 and 1321 by the elastic body 1327 so that the first wings 1322a and 1322b provided in the radial direction are connected to the rotation speed The first wings 1322a and 1322b can be drawn or drawn from the wing receptors 1321a and 1321b.

The first wings 1322a and 1322b fastened by the elastic body 1327 are subjected to the centrifugal force in the radial direction by the rotation of the rotating body 132 at a high speed and the centrifugal force acts on the first wings 1322a and 1322b by the self weight of the first wings 1322a and 1322b 1327 are contracted by the elastic force of the elastic body 1327. In contrast, That is, by the balance between the elastic force of the elastic body 1327 and the centrifugal force of the rotary body 132, the elastic body 1327 is stretched or contracted, and the first wings 1322a and 1322b contact the wing receptors 1321a and 1321b Or the like.

Therefore, the rotating body 132 having the wings extended from the wing receptors 1321a and 1321b by the first wings 1322a and 1322b can scatter the inflowed salt particles to a long distance, and conversely, 1322a and 1322b are drawn into the wing receptors 1321a and 1321b and the wings are shortened, the swirling particles 132 can scatter the inflowed salt particles to a close distance.

As described above, the first vanes 1322a and 1322b can be coupled with the inside of the vane receivers 1321a and 1321b and the elastic body 1327. [ Specifically, as shown in Fig. 3, the first wings 1322a and 1322b inserted into the wing receptors 1321a and 1321b are connected to at least one of the wings 1322a and 1321b protruding from one side end in the direction of the wing receptors 1321a and 1321b And the wing receivers 1321a and 1321b may include at least one second elastic body guide portion 1326 on the inner side of the first elastic body guide portion 1325 opposite to the first elastic body guide portion 1325 Both ends of the elastic body 1327 can be fixedly coupled to the first elastic body guide portion 1325 and the second elastic body guide portion 1326, respectively.

According to another embodiment, the sealing members 1323a and 1323b may be formed of a shielding film 1330a of a stretchable material that can cover the gap between the entrance and exit holes and the first vanes 1322a and 1322b, as shown in FIGS. , 1330b. The shielding films 1330a and 1330b having both ends fixed to the first and second wings 1322a and 1322b are connected to the shielding films 1330a and 1330b of the stretchable material as the first wings 1322a and 1322b are drawn and drawn, Are simultaneously stretched and contracted so that the gap between the inlet and outlet vents and the first vanes 1322a and 1322b is shielded from the outside and a flat appearance is maintained so that no particle is formed on the surface of the vane, 100). ≪ / RTI >

5 to 7 are views showing the appearance of a rotating body according to another embodiment of the present invention.

2, the rotating body 132 according to an embodiment of the present invention may have a width such that the wing receptors 1321a and 1321b are formed over the entire length of the rotating body 132, According to another embodiment of the present invention, as shown in Fig. 5, the rotating body 132 is formed with a plurality of rows in which a plurality of wing receptors 1328a are arranged along the longitudinal direction of the rotating body 132 And a plurality of wing receivers 1328a having a predetermined width along the longitudinal direction of the rotating body 132 can be spaced apart from each other. The plurality of wing receptacles 1328a disposed in the respective rows may be arranged to be staggered with respect to the circumferential direction, or may be disposed so as to overlap with each other.

For example, as shown in Fig. 5, a plurality of wing receivers 1328a are disposed apart from each other in the first row of the rotating body 132, and the position of the wing receiver 1328a of the first row A plurality of vane receivers 1328a can be spaced apart from each other. Of course, the first wing 1329a is inserted into each of the wing receptacles 1328a, and a sealing member (preferably a shielding film 1330a) is provided at a portion where the wing receptacle 1328a and the first wing 1329a overlap each other .

In this case, unlike the previous embodiment, when the rotational speed of the rotating body 132 is changed to a short cycle (or a high frequency), the salt is scattered by the blades having different lengths at different positions with a time lag, The drop point of the salt can be further diversified and the salt can be uniformly loaded in the warehouse. In this case, the length between the wing receiver disposed in the first row and the wing receiver disposed in the second row may be shorter than the distance between two adjacent wing receivers in the above embodiment.

According to another embodiment, a plurality of wing receptors 1328a may be formed on the outer circumferential surface of the rotating body 132 as described above. However, the present invention is not limited to this, 1331a, and 1331b.

6, at least one wing receiver 1328a may be disposed on the first row of the rotating body 132 so as to have a width along the longitudinal direction on the outer circumferential surface thereof, At least one wing receptacle 1328b is disposed in the second row of the wing receptacle 1328a so as to be offset from the wing receptacle 1328a disposed in the first row, The second wing 1331a may be disposed in the second row and the second wing 1331b may be disposed adjacent to the second row in addition to the wing receptacle 1328b at a predetermined interval.

7, at least one wing receiver 1328a may be disposed on the first row of the rotating body 132 so as to have a width along the longitudinal direction on the outer circumferential surface thereof, and the rotating body 132 The second wing 1331a may be disposed so as to be staggered with the wing receptacle 1328a disposed in the first row.

According to this embodiment, it is possible to prevent the problem that salt is loaded at a specific position when the salt is loaded by scattering the salt with various widths and various lengths of wings at various positions.

Control method

According to an embodiment of the present invention, when the conveyor 120 is a belt conveyor, although not shown in the drawings, the load applied to the conveyor 120 is measured inside the belt at the end of the conveyor 12 A load cell (not shown) may be provided. At this time, the control unit 160 may control the rotational speed of the rotating body 132 according to the weight of the load measured from the load cell.

That is, when the load applied to the end of the belt is heavy, the control unit 160 rotates the rotating body 132 at high speed and rotates the rotating body 132 at a low speed when the load is light, It is preferable to scatter and spray the salt at a point far from the salt spraying apparatus 100, that is, deep inside the salt warehouse, and scatter a relatively small amount of salt to the nearest point so as to uniformly load the salt in the salt storage .

In addition, the control unit 160 may generate a valve opening / closing signal to control opening / closing of the valve provided at the outlet of the hopper 110. At this time, the duty ratio of the valve opening / closing signal can be determined based on the rotational speed of the rotating body 123. That is, when the rotating speed of the rotating body 123 is high, the duty ratio is set to 1 based on the OPEN signal, the duty ratio is set to less than 1 based on the OPEN signal when the rotating speed is low, A large amount of salt can be sent away when the rotation speed of the rotating body 123 is high and a small amount of salt can be sent close to the rotating body 123 when the rotation speed of the rotating body 123 is slow.

As a result, when a large amount of salt is initially loaded on the conveyor, the control unit 160 controls the rotation speed of the rotating body 123 at a high speed, and then, by setting the duty ratio of the opening / closing signal of the hopper valve to 1, The control unit 160 controls the rotation speed of the rotating body 123 to a low speed and then decreases the opening / closing signal duty ratio of the hopper valve to less than 1 to reduce the amount of salt to be supplied to the hopper It is possible to spread the salt of the positive salt in a comparatively close distance and spread the salt in the salt store as a whole, as well as to uniformly load the salt in the whole warehouse. In addition, when a high speed rotation of the rotating body is maintained, Salt Allows efficient loading of large amounts of salt from the inside of the warehouse.

The preferred embodiments of the present invention have been described in detail with reference to the drawings. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
