Abstract

(57) [Summary] (Correction) [Purpose] Tillage where the upper part of the rotary shaft of the claw shaft rotary is largely opened and exposed so that maintenance such as removal and attachment of the tillage claw can be easily performed. A partial cover structure is provided. [Structure] The tiller cover covering the upper part of the rotary shaft of the claw shaft rotary is attached to the tiller cover so that it can be opened upward with one end remote from the tiller as a fulcrum. There is.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an improvement of the tiller cover that covers the outside of the rotary range of the claw shaft rotary so that it can be opened if necessary.

[0002]

[Prior art]

 Conventionally, as a conventional technique of this seed tilling section cover, a front cover covering a portion from the front surface of the pawl shaft rotary to the upper front half is fixed to the machine frame side of the tilling section such as a transmission case. However, it is known that the rear cover is hinged to the rear end of the front cover so that the rear cover can be opened upward, and the rear cover can be opened upward as necessary (for example, , Japanese Utility Model Publication No. 61-100908).

[0003]

[Problems to be solved by the device]

 In the conventional type, the upper half of the rotary claw shaft rotary area can be locally exposed by rotating and opening the rear cover upward, but the upper half of the rotary claw shaft rotary area can be exposed. The first half was covered with a front cover, and the entire upper part of the rotary sphere of the pawl shaft rotary was not completely exposed.Therefore, detachment of the cultivating claw or cultivating shaft cylinder etc. The maintenance cannot be easily performed from above the pawl shaft rotary without any obstruction, and because the rear cover rotates with the side close to the machine such as a cultivator as a fulcrum, it may interfere with the machine. There was a problem that it was not opened to the public due to restrictions. According to the present invention, the upper part of the rotary sphere of the claw shaft rotary is fully open and exposed so that maintenance such as detachment and attachment of the cultivating claw or the cultivating shaft cylinder can be performed very easily. The present invention provides a partial cover structure.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a tillage part cover that covers the upper part of the rotating area of the pawl shaft rotary is opened to the tiller part machine frame with one end far from the tiller as a fulcrum. It has an attached tiller cover structure.

[0005]

[Effect of the invention]

 According to the structure of the present invention, the tiller cover is rotated and opened to the side away from the cultivating machine body, and the upper part of the rotation range of the pawl shaft rotary is exposed to a large extent, so that the pawl shaft roll is exposed. It is possible to easily perform maintenance such as attachment and detachment of the tilling claws and the tiller shaft cylinders from above without obstruction. Further, since the open tillage section cover is located in the tray on the side away from the tiller machine body, it is possible to prevent loss of parts during maintenance by placing detachable parts such as tiller claws on it. There is also a side effect.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. In the cultivator (T), an engine (9) is mounted on a frame (8) connected to a mission case. The driving wheels (11) and (11) are rotationally driven by the power transmitted from the engine (9) to the left and right axles (10) and (10) through the transmission mechanism in the mission case so as to travel. It is configured to carry out driving operation at the grip of the steering handle (12) extended from the mission case, and the transmission case (5) is attached to the PTO section of the mission case. The cultivating section (R) can be detachably equipped by interlocking connection.

The cultivating part (R) is of a center drive type and comprises a transmission case (5) and a bezel extending from the lower part of the transmission case (5) in the front-back direction. -A holder (16) for attaching the depth gauge (14) to the vertical adjustment is provided at the extended end of the tillage section machine frame (4) composed mainly of the frame (6). , The upper cover (2) that covers the upper part of the rotating circle of the pawl shaft rotary (1) horizontally supported horizontally at the lower end of the transmission case (5) and hangs down from the left and right ends thereof. A tillage section cover provided with side covers (2c) (2c) is mounted on the tillage section machine frame (4). The pawl shaft rotary (1) has a plurality of brackets provided on the outer periphery of a cultivating shaft cylinder which is fitted to a cultivating shaft laterally supported by a transmission case (5). It is equipped and configured.

Therefore, the upper cover (2) is provided with a bevel on the extended end portion of the beam (6) of the tiller machine frame (4), that is, on the side far from the body of the tiller (T). -It is mounted rotatably around the axis of the horizontal horizontal shaft (3) extending from the horizontal direction (6) to the left and right, and as shown by the phantom line, the horizontal cultivator (3) is used as a fulcrum to cultivate the tiller ( When the upper cover (2) is located so that it can be rotated and retracted to the side away from T), and the upper cover (2) covers the upper part of the rotation range of the pawl shaft rotary (1) (the position shown by the solid line). The front part of the cover is superposed on the receiving part provided on the tiller frame (4) and is fixed by a one-touch stopper (15) such as a wing bolt.

Although the drawings of the embodiments show an embodiment applied to a center-drive type tiller, the structure of the present invention can be applied to a side-drive tiller in substantially the same manner. is there.
