Description

Rotary {A rotary}

The present invention relates to a rotary, and more particularly, to a rotary for a multipurpose tiller having a cutting function, as well as a soil crushing and grading operation in a narrow area or a sloping place by allowing the lateral position of the rotary blade to be variable.

Generally, soil cultivation and soil selection work is done before farming. It is called "rotary work", and it is possible to connect various working machines to front and rear of agricultural equipment such as tractor by changing worker's usage to suit tillage, weeding, harvesting, transportation etc. Various farming operations can be performed.

On the other hand, the types of working machines that use the power of the tractor include a cutting machine for cutting vegetation and weeds, and a rotary for crushing and grading soil. Most of the above cut-offs are for cutting flat, wide-area vegetation. It is impossible to work on a terrain with narrow terrain and severe bending. Also, since the rotary can not change the position between left and right, It is difficult to perform the rotary work on the inner wall side of the vinyl house.

Next, there is a small-sized cutter that can be operated while the operator is walking by mounting a small-sized jean in addition to the cutter mounted on the above-mentioned tractor. However, this method has a disadvantage in that it is possible to cut the vegetation in a narrow area, but the cutting blade is small and the operation takes a long time.

In addition, since the tractor is expensive, it is difficult to purchase the tractor at a small farmhouse. Therefore, a manager using a self-engine equipped with an inexpensive equipment can be used. However, There is a problem in that the efficiency of the work is lowered because the speed is slow.

On the other hand, there are tillage machines that are used in various fields with less expensive agricultural machinery than the above-mentioned expensive tractors, and there are also rotary machines that are attached to tillage machines and used.

The rotary is much more economical than the tractor because it uses the rotating power of the tiller without the need for any additional power. The rotary power of the tiller is transmitted through the chain of the rotary drive shaft, The turning blade rotates at a high speed and performs soil crushing, soil picking and weaving, usually called rotary work.

As described above, according to the present invention, by adjusting the width of the driven shaft 150 and the rotary drive shaft 161 connected to the driven shaft by the operation of the guide handle 151, (164) can also be changed in the lateral position, so that it can be worked in various widths according to the width of the furrows to be worked by the grower, and the work can be performed by adjusting the interval of the rotary blade (164) Do.

In addition, the rotary blade 164 can be used in various working machines by changing the rotary blade 164 according to the application.

Since the rotary drive shaft 161 that has conventionally been rotated by one axis is configured by being divided into the first rotary drive shaft 161a and the second rotary drive shaft 161b in the present invention, the space of the bottom of the rotary 100 is secured, This is easy. Therefore, after sowing, it is possible to remove only the weeds of the furrows without damaging the crop grown in the ditches, or connect and utilize various working machines.

Meanwhile, in the present invention, the conveyance system of the driven shaft 150 on the driven shaft guide 153 is not limited to the screw rotation type. In FIGS. 2, 3A, and 3B, a method of moving the driven shaft 150 on the driven shaft guide 153 in the axial direction is shown by a screw rotation method. However, as in the hydraulic cylinder, It is of course possible to substitute other possible devices.

Next, with reference to FIGS. 4A and 4B, the constituent elements and driving principles of the cultivator rotary according to another embodiment of the present invention will be described in more detail.

4A is a partial perspective view illustrating a slave shaft and a slave shaft guide according to another embodiment of the present invention.

FIG. 4B is a view illustrating a driving principle of a driven shaft according to another embodiment of the present invention.

Figs. 4A and 4B show another transporting method on the follower shaft guide of the driven shaft, which comprises a frame 110 constituting a rotary body; A cultivator coupling plate (120) coupled to a cultivator at a center of a front upper portion of the frame; A driven shaft guide (253) connected to the frame; A slave axis 250 provided on both left and right sides of the slave axis guide so as to be adjustable in length; A longitudinally variable interlocking shaft 130 for transmitting the power of the tiller to the driven shafts and rotating the driven shafts; And a rotary drive shaft (161) spaced apart from the slave shaft in parallel and connected to the chain pulley (141) and rotated by receiving a rotational force of the slave shaft; And the manner in which the driven shaft 250 is axially transported on the driven shaft guide 253 is different from that of the embodiment of the present invention.

4A and 4B, the follower shaft guide 253 has a hollow cylindrical outer circumferential surface with a fastening hole 255 and the driven shaft 250 has a plurality of fastening portions 254 The slave shaft 250 is inserted into the slave shaft guide 253 and one of the plurality of coupling portions 254 is fastened to the coupling hole 255 with the coupling member 256 , And the width of the follower shaft 250 can be adjusted by the screw coupling method on the driven shaft guide 253 according to the axial positional movement.

The follower shaft 250 includes a first driven shaft 250a and a second driven shaft 250b that are adjustable in length on the left and right sides of the driven shaft guide 253, Includes a first rotary drive shaft 161a and a second rotary drive shaft 161b connected to the first driven axis 250a and the second driven axis 250b respectively by a chain pulley 141, The width g1 of the first driven shaft 250a and the second driven shaft 250b and the width g2 of the first rotary drive shaft 161a and the second rotary drive shaft 161b ) Can be adjusted simultaneously.

On the other hand, when crops are sown through rotary work on the cultivated land and after a certain period of time, weeds grow on the furrows, so weeding work is necessary. By the way, it is not easy to obstruct the growth of crops growing on the fields, and it is difficult to enter agricultural equipments such as bulky tractors because the breadth of the troughs is narrow. Therefore, the weeding of the furrows wastes a lot of time and labor and causes difficulties for farmers to do manually.

The tiller rotary according to the present invention can adjust the lateral width g1 by varying the position of the driven shafts 150 and 250 on the slave shaft guides 153 and 253, It is possible to set the position of the rotary drive shaft 161 provided with the rotary blade 164 in accordance with the width of the rotary shaft 161.
