The present invention relates to a gravel separation and removal device of the field, more specifically using a plurality of gravel separation transfer blades provided on the front side by separating the gravel within a certain depth to the surface of the field, and then again work It relates to a gravel separation and removal device of the field is configured to collect by moving to the side.

In general, tillage of the field before the sowing of the field is done tilling work, such as tillage of the field to a constant depth to plow the field after the plowing work, and then proceeds to the clay work and the rest operation.

At this time, the work of plowing the field to a certain depth and the compaction work to crush the soil is usually performed by a device such as a rotorbait, but the gravel exposed to the outside in this process is removed by manual work.

In addition, when gravel work or plowing the field to a certain depth, a lot of gravel existing in the field collides with the tilling blade of the device causes a problem that causes damage and work load.

In order to improve this problem, the work of separating and removing the gravel buried within a certain depth of the field before the tilling work to plow the field should not only prevent damage to the tilling device but also reduce the workload. Automatic separation and removal of gravel has not been developed.

The present invention has been made to improve such a conventional problem, by using a plurality of gravel separation transfer blades provided on the front side to expose the gravel within a certain depth to the surface of the field to separate, then move it to one side again The purpose of the present invention is to provide a device for separating and removing gravel from the field, which can reduce the workload and reduce the work load and increase productivity of the tilling work.

In order to achieve the above object, the present invention transmits the power transmitted from the drive shaft of the engine to the blade drive shaft and the first and second travel orbit wheels through the first and second power transmission means, In the gravel separation and removal device of the field configured to rotate the pivot bar connected to the operation handle by the first bending bar and the connecting rod, the second bending bar according to the vertical rotation, the gravel separation transfer blade to the blade drive shaft of the rotation bar It is provided with a blade interval, the gravel separation transfer blade is configured to rotate left and right symmetrically around the center of the blade on the blade driving axis while the trajectory of the blade is configured to rotate in a spiral to the left or right gravel separated from the field It provides a gravel separation and removal device of the field, characterized in that the automatic transfer to the side.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

1 and 2 is a perspective view showing a gravel separation and removal device of the field according to the present invention, Figure 3 is a perspective view showing a gravel separation transfer blade of the gravel separation and removal device of the field according to the invention, Figure 4 Operational state diagram showing the operating state of the gravel separation and removal device of the field according to the invention.

According to one embodiment of the present invention, as shown in Figure 1, the first moving track wheel 21 and the second moving track wheel 22 are installed in front and rear sides of the body 50, respectively, the body 50 The drive shaft 42 is driven by the engine 40 is installed in the center of the), the gravel separation transfer blade 15 located on the front side of the first travel orbit wheel 21 is the front side end of the body 50 It is comprised so that it may rotate to the up-down direction by the rotation bar 16 couple | attached to the rotation bar 16, The fixed horizontal axis | shaft 14 is fixedly installed in the interruption part.

In addition, the operating handle 20 is rotatably coupled to the fixed handle 10 fixedly installed at the rear side of the body 50.

At this time, the first power transmission means 13 and the second power transmission means 12 are the power of the drive shaft 42 driven by the engine 40, respectively, the blade drive shaft 25 and the first and second travel orbit wheels ( 21, 22) as a power transmission device, and since it is a conventional configuration consisting of a sprocket and a chain, the description of the specific configuration and operation will be omitted.

A pair of second bending bars 18 are rotatably coupled to the fixed horizontal shaft 14, and the connecting rods 17 are successively coupled to the second bending bars 18 so as to be rotatable. There is a first bending bar 19 is coupled to the elastic stretching of the length by the tension spring, the first bending bar 19 is rotatably coupled to the operating handle (20).

Accordingly, as shown in FIG. 2, when the operation knob 20 is rotated to the rear side, the blade driving shaft 25 and the plurality of blade driving shafts 25 connected by the first bending bar 19, the connecting rod 17, and the second bending bar 18 are formed. Gravel separation transfer blade 15 is lowered to the ground by its own weight, and as shown in Figure 1 rotates the operation handle 20 to the front side while the blade drive shaft 25 and a plurality of gravel separation transfer blade is pulled Ascend from the ground.

On the other hand, the gravel separation transfer blade 15 according to the present invention is installed to be rotated up and down by the rotation bar 16 coupled to the rear end side of the body 50 is located on the front side of the body 50, Therefore, it is configured to completely prevent the safety accident of the worker located in the rear side that can occur during the work process.

In addition, the gravel separation transfer blade 15 according to the present invention is fixed to the blade drive shaft 15 provided to be rotatable at the front side end of the rotation bar 16 at a fixed interval, as shown in Figure 13 The dog blades are arranged to be symmetrical about the center blade located in the center of the blade driving shaft.

Moreover, the gravel separation transfer blade 15 is installed so that the trajectories drawn by the thirteen blade ends spirally configured so that the gravel of the field is automatically transferred in either of the left and right directions.

Referring to the operation of the present invention constituted as described above, when the first operation knob 20 shown in FIG. 1 is switched to the state shown in FIG. 2, the first and second bending bars 19 and 18 rotate while being gravel. The separation transfer blade 15 is placed on the field by its own weight.

At this time, when power is transmitted to the first and second power transmission means 13 and 12 through the drive shaft 42 while the engine 40 is operated, the blade drive shaft 25 and the first and second travel orbit wheels 21 and 22. This drive, so that the 13 devices of the gravel separation transfer blade (15) while moving forward to move the field to a certain depth.

Here, as shown in Figure 4, the thirteen blades of the gravel separation transfer blade 15 are rotated while drawing the spiral trajectory of the blade tip to gradually move the gravel of the field to the right to be stacked on the right side.

In short, the present invention is configured so that the blade tip of the gravel separation transfer blade (15) consisting of 13 blades are rotated while drawing a spiral trajectory to separate the gravel of the field and automatically move to one side to load the gravel of the field Its technical features will be that it can be easily separated and removed from.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention.

Therefore, the substantial scope of the present invention should not be limited by the above-described embodiment, but should be defined by the same structure as the claims as well as the claims described below.

The present invention configured as described above can easily remove the gravel of the field before tilling the field, thereby not only preventing the breakage of the tilling device for plowing or plowing the field, but also reducing the work load, It can provide effects such as increasing productivity.
