  2. delete
  3. In Article 1, The above clutch part (440) is, A control cable (441) connected to the first lever provided in the passenger management device, and A second lever (443) that is coupled to the control cable (441) and coupled to the first leg of the coil spring (445) provided on the lever rotation shaft (442) to operate elastically via a hinge, and A lever operating part (444) that is axially coupled to the lever rotation shaft (442) to rotate with the second lever (443) and form an eccentric part, and A push rod (446) that is coupled to the eccentric part of the lever operating part (444) and moves linearly in a direction perpendicular to the second drive shaft (300), and is elastically supported by being coupled to the second leg of the coil spring (445), A PTO for a riding vehicle kit attachment type, characterized by including a locking part (450) that is axially coupled to a second drive shaft (300) and moves along the second drive shaft (300) by a push rod (446) to be coupled to or separated from a second sprocket (420).
  4. In Paragraph 3, The above locking part (450) is, A locking body (453) that is elastically supported by mounting a tension spring (452), wherein an uneven moving coupling part (451) is formed along the outer surface of the second drive shaft (300) and the inner surface of the central shaft hole so as to be able to move in the axial direction while rotating with the second drive shaft (300); A second locking member (454) formed on the locking body (453) and connected to the first locking member (421) of the second sprocket (420), and A PTO for a riding vehicle kit attachment, characterized by including a locking movement flange (456) that forms a groove to accommodate a push rod (446) and forms an inclined surface (455) according to the rotation angle on the surface where the outer surface of the push rod (446) contacts, thereby moving the locking body (453) in the axial direction.

Description

Kit Attachment Type Power Take Off for Agricultural Vehicles The present invention relates to a kit-attachable PTO for a riding cultivator, and more specifically, to a kit-attachable PTO for a riding cultivator that is differentiated from the existing body-integrated PTO of a riding cultivator by configuring a detachable power take-off device (PTO) in a kit format, thereby achieving compatibility with various implements and ease of use. Generally, cultivators are small, multi-purpose agricultural machines that can perform various tasks in confined spaces such as greenhouses and orchards as well as in fields and paddies by attaching implements such as weeders, tillers, seeders, transplanters, pest control machines, and plastic mulching machines to the rear, and are widely used because they are easy to operate. Tillers are classified into walking cultivators, where an operator performs tasks by manipulating the movement of the cultivator and implements, and riding cultivators, where an operator rides on a power-driven cultivator and operates it while driving. To briefly describe the configuration of a typical riding tiller, a driver's seat for the operator is provided at the front of the vehicle body, and an engine and transmission are mounted on one side to provide the power necessary for driving the tiller and implements, along with a drive shaft and differential for front and rear wheel drive. A frame, connecting means, and a lifting lift are mounted at the rear of the vehicle body to connect implements to the tiller, and a power take-off (PTO) device is mounted on one side of the transmission to extract power from the tiller to the implements. If we look at the configuration of a PTO mounted on an agricultural machine according to the prior art in a general sense through the known technology, for example, Korean Registered Patent No. 10-0032632 comprises a driving shaft connected to an engine crankshaft by a driving clutch, a driving drive line that drives a differential mechanism from the engine crankshaft by a forward/reverse rotation switching device connected to the driving shaft, a PTO shaft that is rotatably fitted from the outside on the driving shaft, a PTO drive shaft connected to the PTO shaft, and a PTO drive line that drives a PTO output shaft from the engine crankshaft by having a PTO clutch disposed on a downstream shaft for power transmission of the PTO shaft. As another example, Korean Registered Utility Model No. 20-0358051 describes a riding rice transplanter in which a transmission receiving power from an engine through a clutch device is mounted on the machine body, a rice transplanter with a rice transplanter arm connected to the output shaft of the transmission is installed, and a fertilizer applicator is installed on the upper front part of the rice transplanter. The machine comprises a power extraction device comprising: an operating bar, the rear end of which is fixed to the drive shaft of the fertilizer roller of the fertilizer applicator and the front end of which protrudes a certain length in the same direction as the output shaft of the transmission; a driven shaft that rotates with the output shaft of the transmission; a rotating disc protruding from the center of the rear side to which one end of the driven shaft is inserted and fixed; and a power transmission means for transmitting power from the output shaft to the driven shaft. As another example, Korean Registered Patent No. 10-0140935 describes an agricultural comprehensive management system configured such that a lateral output shaft is extracted from the side of a reduction gear located on one side of the engine on the side of the driver's seat of the agricultural comprehensive management system, and a front output shaft is provided by extending the input shaft, through which power is supplied to the transmission, forward, and a rear output shaft is provided at the rear of a rear PTO gearbox that receives power from the input shaft and has output shafts on both sides, thereby mounting various types of implements and mounting implements on the frame to perform single operations and 2-3 process operations simultaneously.
