Description

Sprayer {SPREADER}

The present invention relates to a spreader for spraying fertilizers, seeds, and the like.

Fertilizers are used to promote the growth of crops and are used throughout the agriculture. However, conventionally, when powdered or granular fertilizer is sprayed by hand, it is pointed out that when farmers spray the fertilizer directly, the work time is delayed and the human body is adversely affected.

Recently, a fertilizer distributor consisting of a compressor and a spreader has been introduced, but it is difficult for small farmers to use expensive equipment. An agricultural spreader using a compressor in a Korean patent (2014-0018768; 2014.02.13) is disclosed.

The Korean Utility Registration No. 20-275269 also discloses a fertilizer spreader that can be operated manually. However, there is a disadvantage in that it is difficult to pull the lever while holding the handle, and the fertilizer or the like pushes the entirety of the opening / And it is also disadvantageous that the switch can not open smoothly due to the small force of the finger due to the resistance force applied to the lever. In fact, the worker puts the duster into the ground and later sprayed the fertilizer in the form of pulling the lever.

The present invention provides a spreader capable of simply spraying fertilizers and seeds even with small force and small movements in the case of containing fertilizer or seeds.

The present invention provides a spreader capable of regulating or stepwise regulating an application amount.

The present invention provides a spreader capable of adjusting quantities in various stages in adjusting a spray amount in a quantitative manner.

According to an exemplary embodiment of the present invention, a spreader for spreading a spreading material includes a shovel head grounded to the ground, a shovel rod coupled to the shovel head, and a shovel rod, A shovel body including a grip portion coupled to the end portion; A hollow spraying portion through which the spraying material flows into the upper end and discharges the spraying material to the lower end adjacent to the shovel head; And a spray amount adjusting unit including a shutoff plate rotatably mounted in an inner space of the spray unit and spraying the spray material stored in the inner space according to the rotation of the shutoff plate.

In this specification, the spraying material may refer to all materials to be sprayed, such as fertilizer and seeds used for agricultural purposes, and may have various particle states such as granules and powders.

In addition, when the lower end of the spray unit is connected to the spray hole passing through the shovel head, the spray material discharged through the lower end of the spray unit can be guided by the shovel head, It is easy to specify the drop position.

The spray amount adjusting unit may include a rotation shaft for rotatably mounting the shield plate to the spray unit, a rotation lever formed by partially exposing the rotation shaft to the outside of the spray unit, a trigger disposed adjacent to the grip unit for pulling the finger, And a connecting member connecting the rotating lever and the trigger. The connecting member can selectively use a wire, a rod, or the like.

It is easy to spray the spraying material by pulling the trigger when the user grasps the grip.

In addition, the closing plate is rotated to release the closed space of the inner space to spray the spraying material, and then return the blocking plate to the closed state again.

A restoring spring can be used to switch from a closed state in which the passage of the inner space is opened to a closed state in which the passage is closed.

Further, it is possible to provide a spray amount adjusting plate rotatably mounted on the spray portion above the blocking plate, and the spray material between the blocking plate and the spray amount adjusting plate can be sprayed according to the rotation of the blocking plate.

In the case where there is no separate spray amount adjusting plate, the spray amount can be adjusted by adjusting the time during which the blocking plate is opened. However, when the spray amount adjusting plate is further provided on the upper surface of the blocking plate, the spray material located between the two plates is sprayed. Therefore, it is advantageous to spray a fixed amount.

In addition, the blocking plate and the spray amount adjusting plate intersect each other in the open state and the closed state. For this purpose, it is preferable that the blocking plate and the spray amount adjusting plate rotate at the same time. For example, when the trigger is pulled and the shutoff plate is switched to the open state, the spray level control plate located at the upper side is switched to the closed state, and the spraying material positioned between the two plates is sprayed.

In addition, a moving slit may be formed in the spraying unit to change the position of the rotating shaft of the spraying amount adjusting plate to an upper position, and the spraying amount of the spraying material may be adjusted by adjusting the distance between the blocking plate and the spraying amount adjusting plate.

Specifically, a rotating hole corresponding to the rotating shaft diameter of the spray amount adjusting plate is formed at both ends of the moving slit so that the rotating shaft of the spray amount adjusting plate is seated and rotated, and a step for limiting the movement of the rotating shaft of the spray amount adjusting plate is formed at the entrance of the rotating hole .

Further, the blocking plate may be provided as an elliptical plate which is arranged to be inclined to the inner space of the spray portion. In this case, it is easier to switch the shutoff plate into the open state as compared with the shutoff plate which maintains the closed state in a state where the shutoff plate is disposed perpendicular to the longitudinal direction of the sprayer. Specifically, the closed state of the blocking plate can be switched to the open state by moving the rotary lever at a smaller angle.

The spreader of the present invention is capable of simply spraying the fertilizer through the rotation of the blocking plate. Especially, by spraying the fertilizer through the rotation of the blocking plate, it is possible to spray the fertilizer with a small force by the gravity of the fertilizer.

In addition, the spreader of the present invention can use a shielding plate and a spraying amount regulating plate which are spaced apart from each other, so that it can be sprayed in a fixed amount.

In addition, it is possible to easily adjust the application amount of the fertilizer by providing a moving slit capable of changing the position of the spray amount adjusting plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, the same numbers in this description refer to substantially the same elements and can be described with reference to the contents described in the other drawings under these rules, and the contents which are judged to be obvious to the person skilled in the art or repeated can be omitted.

1 is a perspective view of a spreader according to an embodiment of the present invention. FIG. 2 is an enlarged perspective view of the periphery of the spray unit shown in FIG. 1, and FIG. 3 is a view for explaining the open and closed states of the shutoff plate. Figs. 4 and 5 are views for explaining a rotating operation of the rotary lever. Fig.

1 to 4, the spreader 100 includes a shovel body 110, a spreader 120, and a spread amount adjuster 130.

The shovel body 110 has a shovel head 111, a shovel rod 115, and a gripper 117.

The shovel head 111 can be sharpened at the tip in order to dig the soil and can guide the fertilizer sprayed by the spray amount adjusting unit 130 to the ground. The shovel rod 115 may be provided in a length up to more than an adult's waist so that the operator can stand and spray the fertilizer, and a multi-stage structure or a sliding structure for adjusting the length can be applied. In addition, the grip portion 117 is made so as to facilitate the user's grip, but can be made of rubber to prevent slippage.

The spraying part 120 may be provided as a hollow pipe and connected to a spray hole 112 formed in the shovel head 111. A lower end of the spraying part 120 is connected to a spray hole 112 formed in the shovel head 111.

When the lower end of the spraying unit 120 is connected to the spraying hole 112 passing through the shovel head 111, the spraying material discharged through the lower end of the spraying unit 120 is guided by the shovel head 111, And it is easy to designate the drop position of the spraying material by using the shovel head 111. [

The spray amount adjusting unit 130 includes a shutoff plate 131 rotatably mounted in an inner space of the spray unit 120. The spray material stored in the inner space may be sprayed according to the rotation of the shutoff plate 131 .

Specifically, the application amount adjustment unit 130 includes a rotation axis 132 for rotatably mounting the shutoff plate 131 on the spray unit 120, a rotation shaft 132 formed by partially exposing the rotation axis 132 to the outside of the application unit 120, A lever 134 disposed adjacent to the lever 133 and a finger 134 for hooking the finger and a connecting member 135 connecting the lever 133 and the trigger 134. [ The connection member 135 can selectively use a wire, a rod, or the like.

When the user grasps the gripper 117, the trigger 134 is pulled to facilitate spraying of the spraying material. 4, the user can pull the trigger 134 to rotate the rotary lever 133, and the blocking plate 131, which rotates together with the rotary lever 133, can rotate. 5, when the user releases the force pulling the trigger 134 and the rigid material does not bend the connecting member, the trigger 134 is urged by the spring disposed in front of the trigger to move the blocking plate 131 to the closed position Can be restored.

On the other hand, after the shutoff plate 131 is rotated to release the closed state of the inner space to spray the spraying material, the shutoff plate 131 must be returned to the closed state again. Referring to the drawing, a rotating shaft 132 is fixed to the center of the blocking plate 131. The rotating shaft 132 rotates the blocking plate 131 clockwise from the viewpoint of the rotating lever 133, The inside of the spraying unit 120 is opened. In this process, the fertilizer generally provides pressure in the downward direction on the upper surface of the blocking plate 131 due to gravity or the like.

That is, the blocking plate 131 lifts the fertilizer from the front portion around the rotating shaft 132, and is pressed down by the fertilizer at the rear portion. That is, the blocking plate 131 receives forces in different directions from the front and rear with respect to the rotation axis 132, these forces cancel each other, and the blocking plate 131 is opened with a relatively small force. This makes it possible to obtain an effect that the plate is opened by a small force as compared with the prior art in which the plate is slid over the entire surface. This can mean that the trigger 134 can open the blocking plate 131 with a small force.

A restoring spring 140 may be used to switch the closed space in which the passageway is closed in the open state of the blocking plate 131 that opens the passageway of the inner space. The restoring spring 140 elastically connects the rotating lever 133 and the spraying unit 120 to automatically return the blocking plate 131 to the closed position.

6 and 7 are views for explaining a spreader according to another embodiment of the present invention. The components of the present embodiment are substantially the same as those of the spreader of the previous embodiment except for the moving slit or the spray amount adjusting plate formed on the spreader, and the detailed description of the same configuration can be applied to the previous embodiments. In this embodiment, The difference from the previous embodiment will be mainly described. For the sake of convenience of understanding and explanation, the same reference numerals are used for the same constituent elements as those of the preceding embodiment.

A shutoff plate 131 and a spray amount control plate 150 are rotatably installed on the spray unit 120 with a predetermined distance therebetween. The spraying material between the blocking plate and the spray amount adjusting plate 150 can be sprayed according to the rotation of the blocking plate.

In the case where the spray amount adjusting plate 150 is placed on the upper part of the blocking plate 131 as in the present embodiment, the amount of the spray amount adjusting plate 150 may be adjusted by adjusting the time during which the blocking plate is in the open state. Is sprayed. Therefore, it is advantageous to spray a fixed amount.

In addition, the blocking plate 131 and the application amount adjusting plate 150 intersect with each other in the opened state and the closed state. In this embodiment, one connecting member is connected to the rotating lever for rotating the blocking plate and the application amount adjusting plate, The blocking plate 131 and the application amount adjusting plate 150 can be rotated at the same time.

Referring to FIG. 7, when the trigger is pulled and the shutoff plate 131 is switched to the open state, the spray amount regulating plate 150 located at the upper side is switched to the closed state, and the spray material located between the two plates is sprayed.

The moving slit 121 may be formed in the sparging part 120 to change the position of the rotating shaft 132 of the sprinkling amount adjusting plate 150 to the upper position, and the moving slit 121 may be formed between the blocking plate 131 and the spray amount adjusting plate 150 The distance can be adjusted to control the application amount of the spraying material.

Specifically, a rotation hole 122 corresponding to the diameter of the rotation axis 132 of the application amount adjustment plate 150 is formed on both ends of the movement slit 121 so that the rotation axis 132 of the application amount adjustment plate 150 is seated and rotated, A step 123 for limiting the movement of the rotation axis 132 of the application amount adjustment plate 150 may be formed at the entrance of the hole 122. The rotating shaft is usually located in the rotating hole through the step. However, if the rotating shaft is moved with a strong force, the slit can be slightly opened when the spreading portion is provided with synthetic resin, so that the rotating shaft can be moved. It is also possible to attach the step to the periphery of the moving slit with an elastic material as the case may be.

8, the blocking plate 131 is disposed at an angle to the spraying unit, not perpendicular to the longitudinal direction of the spraying unit, even when the blocking plate 131 is in the closed state, unlike the previous embodiments.

In this case, the shielding plate 131 is provided as an elliptical plate which is inclined to the inner space of the spraying unit 120, and in comparison with the shielding plate which is maintained in a closed state in a state of being disposed perpendicularly to the longitudinal direction of the spraying unit, It is easier to switch the blocking plate to the open state. Specifically, the closed state of the shutoff plate 131 can be switched to the open state by moving the rotary lever 133 at a smaller angle.

Although the present invention has been described with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that
