Description

duster

[0001] The present invention relates to a sprayer, and more particularly to a sprayer capable of effectively spraying a liquid or solid target.

[0002] The present invention relates to a sprayer, and more specifically, to a sprayer capable of uniformly spraying a solid or liquid substance such as calcium chloride.

[0003] Spreading calcium chloride on road surfaces is essential to ensure road safety during the winter. Calcium chloride plays a crucial role in preventing road freezing, thereby preventing vehicle skidding accidents, and maintaining the smooth flow of traffic during the winter. Various types of spreaders are used to carry out this calcium chloride application.

[0004] Traditional calcium chloride spreaders are primarily mounted on large vehicles and designed to cover wide roads. These large-vehicle spreaders have the advantage of being able to evenly spread a large amount of calcium chloride at once, allowing for the rapid treatment of large areas.

[0005] However, due to the complex structure and large size of such large equipment, there is a limitation that it can only be installed on dedicated vehicles. As a result, it is difficult for ordinary households or small businesses to use such large equipment, and its use is restricted in urban areas or on narrow roads.

[0006] Furthermore, calcium chloride spreaders mounted on large vehicles are costly and require significant resources for maintenance. The fixed structure of such large equipment makes it difficult to adapt to various road conditions, and it also has the disadvantage of making it difficult to control the spraying range, particularly on narrow roads or curved sections. Due to these issues, there has been a growing need for smaller and more efficient calcium chloride spreaders suitable for specific areas or small-scale operations.

[0007] The manual calcium chloride spreader was developed to reflect these demands. The manual spreader has a simple structure and can be used without a separate large vehicle, offering the advantage of being usable in homes or small businesses.

[0008] However, manual sprayers are inefficient for treating large areas because they require the user to exert physical force to operate. Additionally, the spraying range is narrow, and there is the inconvenience of the operator having to manually adjust the spraying area. For these reasons, while manual sprayers may be useful for small work areas, they are not suitable for situations where large areas need to be treated quickly and efficiently.

[0009] Consequently, calcium chloride spraying equipment faces various problems, such as the high cost, complexity, and limited operating environments of large vehicle-mounted equipment, as well as the inefficiency and limited spraying range of manual equipment.

[0010] Therefore, it is necessary to develop a new type of spreader capable of solving these problems. An ideal calcium chloride spreader should be easily installable on standard vehicles or small equipment, allowing for flexible use in various environments.

[0011] Furthermore, there is a need for an efficient design that can increase spraying range and accuracy while reducing the user's workload, all while avoiding complex structures. Against this backdrop, the development of new sprayer technology has become urgently necessary.

[0085] The rotating part (320) rotates and provides centrifugal force to the spraying target accommodated on the upper side, and the spraying target to which centrifugal force is applied can move in a direction of deviation in the diameter direction of the rotating part (320). At this time, the cover part (310) can restrict the direction in which the spraying target deviates, and the spraying target can be sprayed toward the front that is not shielded by the cover part (310). That is, the cover part (310) can shield the side and rear of the rotating part (320) so that the spraying target can move only toward the front.

[0086] The spraying unit (300) may further include a support unit (360) that connects the upper side of the cover unit (310) and the lower side of the storage unit (100) to fix the spraying unit (300) to the storage unit (100). The support unit (360) may fix the cover unit (310) by hanging the cover unit (310) from the lower side of the storage unit (100).

[0087] The motor unit (350) may include a spraying motor (351) that provides rotational force, a spraying motor shaft (352) extending from the spraying motor (351), and a spraying motor cover (353) that covers the spraying motor (351). The spraying motor cover (353) is connected to the lower side of the support unit (360) to protect the spraying motor (351) from external impacts and foreign substances. The spraying motor shaft (352) may pass through the base (340) and be connected to the rotating unit (320). The spraying motor shaft (352) can rotate the rotating unit (320).

[0088] Meanwhile, the rotating part (320) may include a rotating plate (321) that provides a support surface on which a spraying target is placed, a hollow rotating pipe (322) that extends upward from the rotating plate (321) and prevents the spraying target from moving toward the center of the rotating plate (321), a plurality of rotating wings (323) that extend outward from the outer surface of the rotating pipe (322) and partition the space above the rotating plate (321), and a rotating shaft member (325) that extends from the lower surface of the rotating plate (321) and into which a motor part (350) is inserted.

[0089] The rotating plate (321) may have a position where a spray target can be placed by the rotating pipe (322). A spray target may be placed only on the outer side in the radial direction of the rotating pipe (322). The rotating wing (323) may extend in the radial direction from the outer surface of the rotating pipe (322). The rotating wing (323) may apply an external force in a direction perpendicular to the rotating wing (323) to the spray target placed on the rotating plate (321). Through this, the spray target may be supported by the rotating wing (323) and the rotating plate (321) and rotate. That is, centrifugal force may be applied to the spray target by the rotating wing (323).

[0090] The spraying motor shaft (352) can be accommodated in the rotating shaft portion (325). The spraying motor shaft (352) can be fixed to the rotating shaft portion (325). Accordingly, the rotating plate (321) can rotate together with the spraying motor shaft (352).

[0091] Meanwhile, the cover portion (310) may include a cover plate (311) positioned above the rotating portion (320) and facing the rotating plate (321), with a cover hole (312) formed through the lower part of the storage discharge hole (120), a cover wall (313) extending from the cover plate (311) toward the rotating plate (321) to limit the area from which a spraying target placed on the rotating plate (321) escapes, and a hollow cover pipe (314) extending downward from the cover plate (311) to accommodate a part of the rotating pipe (322).

[0092] A spray target contained in the storage unit (100) can move toward the rotating unit (320) through the cover hole (312) formed in the cover plate (311). The cover hole (312) can be positioned at a radial distance from the center of the cover plate (311). The cover wall (313) can be positioned to cover the side and rear of the rotating unit (320). The cover wall (313) can extend downward from the cover plate (311). That is, the cover plate (311) and the cover wall (313) can restrict the path through which the spray target seated on the rotating unit (320) can move. Additionally, the cover pipe (314), together with the rotating pipe (322), can partition the space so that the spray target is positioned at a radial distance from the center of the rotating unit (320). This has the effect of applying a greater centrifugal force to the spray target.

[0093] The rotating part (320) further includes a wing recess (324) formed by sinking downward in a portion adjacent to the rotating pipe (322) among the upper surfaces of a plurality of rotating wings (323), and the lower end of the cover pipe (314) can be received in the wing recess (324) and positioned between the rotating wing (323) and the rotating pipe (322).

[0094] The wing recess (324) can be formed to accommodate the cover pipe (314). This has the effect of preventing the spraying target from moving into the inside of the cover pipe (314) or the rotating pipe (322). Therefore, it has the effect of effectively transmitting centrifugal force to the spraying target.

[0095] Meanwhile, the cover portion (310) may include a cover fastening portion (316) protruding from the outside of the cover plate (311). The cover fastening portion (316) may be used to be fastened to the base (340). The base (340) may include a base plate (341) facing the rotation plate (321) and a base fastening portion (342) protruding outward from the perimeter of the base plate (341). The cover fastening portion (316) and the base fastening portion (342) may be fastened together at once to form a space in which the rotation portion (320) is accommodated inside.

[0096] Additionally, the cover portion (310) may further include a cover fixing portion (315) to which the adjustment portion (330) is attached. The adjustment portion (330) is attached to the cover fixing portion (315) and may be fixed at various positions on the cover portion (310). The specific structure will be described later.

[0097] Meanwhile, the above adjustment unit (330) comprises an adjustment plate (331) coupled to the upper side of the cover plate (311), an adjustment wall (332) extending downward from the adjustment plate (331) and located on the outer side of the cover wall (313) and limiting the area where a spraying target seated on the rotating plate (321) escapes to the outside of the spraying unit (300), an adjustment hole (333) formed by penetrating the adjustment plate (331), an adjustment fixing member (336) penetrating the adjustment hole (333) and fixing the adjustment plate (331) onto the cover plate (311), an adjustment guide (335) extending downward from the lower surface of the adjustment plate (331) to accommodate the adjustment fixing member (336) and guide the movement of the adjustment plate (331), and an adjustment guide (335) extending upward from the circumference of the adjustment hole (333) and It may include a control hole rib (334) that supports the control fixing member (336).

[0098] The above adjustment fixing member (336) can connect the adjustment plate (331) and the cover part (310) through the adjustment hole (333). The above adjustment fixing member (336) can be connected to the aforementioned cover fixing part (315). The above adjustment fixing member (336) can be provided in a shape such as a bolt. The above adjustment fixing member (336) can be located in various areas of the adjustment hole (333). Once the position is fixed, the above adjustment fixing member (336) can be placed only in the fixed position of the adjustment hole (333).

[0099] The above-mentioned control wall (332) can limit the area where a spraying target, to which centrifugal force is applied on the rotating part (320), can escape from the spraying part (300). When the control fixing member (336) is fixed while positioned in front of the control hole (333), most of the control wall (332) can be positioned so that most of its area overlaps with the cover wall (313). On the other hand, when the control fixing member (336) is fixed while positioned behind the control hole (333), only a portion of the control wall (332) can be positioned so that it overlaps with the cover wall (313). Therefore, the control wall (332) can limit most of the area where a spraying target can escape from the spraying part (300).

[0100] That is, the above-mentioned control unit (330) can set the trajectory of the spraying target being sprayed from the spraying unit (300). If the above-mentioned control unit (330) moves forward, the area where the spraying target is sprayed may be narrowed. If the above-mentioned control unit (330) moves backward, the area where the spraying target is sprayed may be narrowed.

[0101] The above adjustment unit (330) may be arranged in pairs on the cover unit (310). The pair of adjustment units (330) may be adjusted individually. The user may fix the adjustment unit (330) at various positions according to the desired spraying trajectory.

[0102] Meanwhile, the adjustment hole rib (334) may extend upward along the circumference of the adjustment hole (333) from the upper side of the adjustment plate (331). The adjustment hole rib (334) may support the lower side of the adjustment fixing member (336). The adjustment hole rib (334) may perform the function of assisting in the connection of the adjustment fixing member (336).

[0103] Meanwhile, a sprayer (1) according to one embodiment of the present invention may further include an opening / closing part (400) disposed between the storage discharge hole (120) and the cover hole (312) to control the degree of opening of the storage discharge hole (120).

[0104] The above opening / closing part (400) may be located between the storage part (100) and the cover part (310). The above opening / closing part (400) can adjust the opening area of ​​the storage discharge hole (120). Accordingly, the above opening / closing part (400) can control the flow rate of the spraying target moving through the storage discharge hole (120).

[0105] The above opening / closing part (400) may include an opening / closing member (410) that is movable in the forward / backward direction between the storage discharge hole (120) and the cover hole (312) to adjust the opening area of ​​the storage discharge hole (120), and a support member (420) that supports the opening / closing member (410) so as to be slidably supported.

[0106] The opening / closing member (410) can be slidably moved in the forward and backward directions. The opening / closing member (410) may be movably provided on the support member (420) between a first position that completely closes the storage discharge hole (120) and a second position that completely opens the storage discharge hole (120).

[0107] The position where the above-mentioned opening / closing member (410) moves to the furthest forward can be defined as the first position, and the position where the above-mentioned opening / closing member (410) moves to the furthest rear can be defined as the second position.

[0108] Meanwhile, the above-mentioned opening / closing member (410) may include an opening / closing body (411) movable between the storage discharge hole (120) and the cover hole (312), an opening / closing handle (412) provided to be gripped and extending rearward from the opening / closing body (411), and an opening / closing stopper (413) protruding upward from the opening / closing body (411) to prevent the opening / closing body (411) from moving forward from the first position.

[0109] When the opening / closing member (410) moves to the first position, the opening / closing stopper (413) can come into contact with the outer surface of the storage body (110). The opening / closing member (410) can protrude higher than the gap between the opening / closing body (411) and the storage discharge hole (120) to perform the stopper function.

[0110] Additionally, the support member (420) may include a support base (421) located at the lower part of the opening / closing body (411) to support the lower side of the opening / closing body (411), a support cover (422) coupled to the upper side of the support base (421) to prevent the opening / closing body (411) from moving upward, and a support stopper (423) protruding from the support base (421) and positioned to face the rear end of the opening / closing body (411) to prevent the opening / closing body (411) from moving backward from the second position.

[0111] When the opening / closing body (411) moves to the first position, the support stopper (423) can come into contact with the opening / closing body (411). That is, the support stopper (423) can restrict the movement of the opening / closing member (410) while in contact with the opening / closing body (411).

[0112] The above opening / closing unit (400) may have a support base (421) installed on a movable plate (550), an opening / closing member (410) seated on the support base (421), and a support cover (422) connected to the support base (421) above the opening / closing member (410). When such connection is implemented, the opening / closing member (410) may be restricted from moving further back than the second position by the support stopper (423) when moving backward. Additionally, when all components such as the storage unit (100) are installed, the opening / closing member (410) may be restricted from moving further forward than the first position by the storage unit (100) when moving forward.

[0113] Through this, the opening / closing part (400) can effectively control the degree of opening of the storage discharge hole (120) by moving within a predetermined position. This allows the user to control the amount of spraying of the target object.
