More particularly, the present invention relates to a shovel equipped with a vibration generating means, and more particularly, to a shovel equipped with a vibration generating means capable of vibrating the shovel vertically to dig a pit on the ground, It is about the shovel.

In general, a shovel is used to dig a small amount of land to move soil, and in particular, it can be used as a culvert for digging a pit that does not require a large digging means such as an excavator, In order to prevent damage to the roots, they work on the basin, which digs the circumference of the tree roots.

However, since the conventional shovel simply penetrates only by the force of the operator, even if the ground surface of the work space is hardened a little, the operator can not easily dig the ground. Therefore, it is difficult to carry out a crushing work for digging a pit of a predetermined size, In the process of planting a plant for transplanting, it is impossible to cut roots or stalks that are clogged in the ground at one time, but cutting is performed in a form of digging a part over several times. Therefore, There is a problem that the damage to the root of the tree is increased, and also the worker concentrates his / her power on the work.

The 'vibrating shovel' disclosed in the conventional patent document 10-0952537 includes a cylinder formed in the inside of the shovel, an elevating operation stand installed to penetrate the cylinder, a blade mounted on the lower end of the elevating operation stand, An elevating operation member provided to be connected to the upper end of the elevating operation stand so that the elevating operation unit is vertically operated, and a four-bar link mechanism connected to the elevating operation member for reciprocating motion, and has a complicated structure, There was a problem.

On the other hand, the registered utility model No. 20-0114169 entitled " engine-driven power injection " rotates a camshaft by the output of the engine, and the push rod, which is connected to the camshaft by a connecting rod, So that the rotation output of the engine can be converted into the forward and backward reciprocating motion by the interlocking operation of the cam to perform the grounding work. The above-described prior art also has a complicated structure and is bulky and heavy, . In addition, in the case of the above-described prior art, there is a problem that it is difficult to maintain a desired vibration amount because a clearance is generated at a connecting portion of each link.

In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a vibration generating device which is capable of vibrating up and down the shovel, The object of the present invention is to provide a shovel equipped with means.

In order to accomplish the above object, the shovel equipped with the vibration generating means according to the present invention is provided with a shovel having a predetermined length and a blade at the bottom of the shovel, and is installed firmly in the middle of the shovel, A driving gear which is housed in the case and is connected to the power source and rotates; a driven gear which is disposed in parallel with the driving gear and rotates in engagement with the driving gear; And a weight mounted symmetrically with respect to the shovel so as to be eccentric to the gears.

According to the present invention, when the shovel is mounted on the shovel, the shovel is vibrated up and down, so that the shovel operation for digging the pit using the shovel can be performed more easily and quickly.

In addition, since the vibration generating means has a relatively simple structure, the failure occurrence rate of the vibration generating means is low, and subsequent maintenance and repair can be easily performed.

In addition, since the overall structure of the vibration generating means can be reduced and the weight can be reduced due to the simplified structure, the workability can be improved even in the state where the vibration generating means is mounted on the shovel.

In addition, it is possible to minimize the damage of the root of the tree during the work of digging the circumference of the tree roots for planting landscape plants, and it is possible to work with less force, thereby improving the work efficiency

The shovel equipped with the vibration generating means according to the present invention is a device in which a shovel vibrates up and down to perform a work of digging a pit on the ground or an operation of transferring a tree more easily. 4.

Generally, it is difficult to insert the blades 20 into the soil when the soil is dug in the hard soil, and when the blade 20 is touched by the roots when the trees are scratched, it is difficult to work. In order to solve the above problems, the present invention is equipped with a vibration generating means so that the shovel vibrates up and down.

The shovel equipped with the vibration generating means according to the embodiment of the present invention includes a shovel 10 having a predetermined length, a blade 20 fixed to the lower end of the shovel 10, A case 110 having a handle 30 and provided at an intermediate portion of the shovel 10 to form a predetermined space S therein; A driven gear 130 disposed in parallel with the driving gear 120 and rotated in engagement with the driving gear 120; a driving gear 120 coupled to the driving gear 120; And a weight 140 eccentrically mounted on the driven gear 130 and mounted symmetrically with respect to the shovel.

The case 110 may be manufactured in various shapes and sizes within a range of forming a space S in which the driving gear 120, the driven gear 130 and the center shaft 160 described later are accommodated. The case 110 is provided at a middle portion of the shovel 10 to form a predetermined gap from the blade 20 and includes a driving gear 120, a driven gear 130, and a weight 140, To the shovel 10 and the blades 20, as shown in Fig. Then, the worker can step on the top of the blade 20 through the space separated between the blades 20 and the case 110.

The driving gear 120 and the driven gear 130 are formed in the same size and shape. The driving gear 120 is connected to a power source 150 such as a prime mover and rotated, and the driven gear 130 is engaged with the driving gear 120 and rotated. The drive gear 120 and the driven gear 130 may be symmetrically disposed on both sides of the shovel 10. More specifically, the center of the connecting line L1 connecting the driving gear 120 and the center shaft 160 of the driven gear 130 is perpendicular to the center line L2 of the shovel 10.

The weight 140 is fixed to the drive gear 120 and the driven gear 130 in an eccentric manner symmetrically with respect to the shovel. At this time, the weight 140 may have the same size and shape as well as the mass. The weight 140 is fixed to the drive gear 120 and the driven gear 130, and an unbalanced force generated while rotating around the center of the gears 120 and 130 generates vibration in the direction of the shovel.

The operation of the vibration generating means constructed as described above will be described below. First, the driving gear 120 in the case 110 receiving the rotational force from the power source 150 rotates in engagement with the driven gear 130. At this time, the weight 140 is mounted on the driving gear 120 and the driven gear 130. The weight 130 is mounted on the driving gear 120 and the driven gear 130 and rotates while rotating the weight 130 in the direction of the center of the driving gear 120 and the driven gear 130 Lt; / RTI > For example, when the weight 130 rotates while descending, it generates the accelerations a1 and a2 in the vertical direction parallel to the shovel 10.

The acceleration (a1, a2) generated by the above-mentioned action can easily work such as digging the ground or cutting the root of the tree by using the blade 20 by vibrating the shovel vertically. According to the present invention, the handle 30 may have a T shape, and an acceleration device connected to the power source 150 may be mounted.

According to an embodiment of the present invention, the weight 140 is fixed at a position symmetrical to the driving gear 120 and the driven gear 130.

When the rotational force is applied to the driving gear 120 as described above, the driving gear 120 and the driven gear 130 meshed with each other rotate at the same speed. At this time, the driving gear 120 and the driven gear 130 The acceleration in the center direction is generated in the eccentrically fixed weight body 140.

The acceleration generated in the weight 140 of the driving gear 120 and the driven gear 130 is transmitted to the center axis of the shovel 10 and the acceleration a1 and a2 in the vertical direction parallel to the center line of the shovel 10, And can be classified into vertical acceleration b1 and acceleration b2.

At this time, when the weights 140 are provided in the same shape and mass and are fixed at positions symmetrical to the driving gear 120 and the driven gear 130 with respect to the shovel 10, The acceleration components b1 and b2 may cancel each other because they are the same in magnitude and opposite in direction. In addition, the acceleration components a1 and a2 in the direction parallel to the shovel 10 are added without being canceled each other, and the vibration amount generated by the weight 140 when the driving gear 120 and the driven gear 130 rotate Can be increased.

According to an embodiment of the present invention, the weight 140 is attached to the front and rear surfaces of the driving gear 120 and the driven gear 130 so as to face each other.

When the weight 140 and the weight 140 are both attached to the front and rear surfaces of the driving gear 120 and the driven gear 130, the weight of the weight 140 is increased. In addition, the weight 140 can be structurally stable because the weight of the weight 140 is dispersed on both sides when attached to both the front and rear surfaces of the driving gear 120 and the driven gear 130.

The driving gear 120 and the driven gear 130 are coupled to a pair of central axes 160 connected to the inner surface of the case 110 by a bearing 170, And is connected in the form of being inserted.

The bearing 170 connects the center shaft 160 and the case 110 so that the center shaft 160 can be rotatably mounted on the case 110. Accordingly, the power source 150 rotates the central shaft 160 connected to the driving gear 120, and the driven gear 130 engaged with the driving gear 120 is rotated in parallel with the central shaft 160 It is possible to rotate about the central axis arranged.

According to the present invention, when the shovel is mounted on the shovel, the shovel is vibrated up and down, so that the shovel operation for digging the pit using the shovel can be performed more easily and quickly. In addition, the vibration generating means has a relatively simple structure, so that the failure occurrence rate of the vibration generating means is low, and subsequent maintenance and repair can be easily performed. Further, since the overall structure of the vibration generating means can be reduced and the weight can be reduced due to the simplified structure, the workability can be improved even in the state where the vibration generating means is mounted on the shovel. In addition, it is possible to minimize the damage of the root of the tree during the work of digging the circumference of the tree roots in order to plant the landscape water, and it is also possible to work with less force, thereby improving the work efficiency
