Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a rotary tillage machine, and in particular, the present invention relates to a rotary tiller, and in particular, a rotary tiller using a moving vehicle, etc. Easily prevents the rear cover from shaking due to the vibrations of the moving vehicle when transporting the tilling machine. The invention relates to a rotary tiller that can be used for tilling.

0002

[Conventional technology]

Conventionally, a rotor is attached to the rear of a tractor so that it can be raised and lowered via a three-point linkage mechanism. On Lee tilling machines, there is a A rear cover that can be moved downward is installed to prevent tilled soil from scattering to the rear. something is known.

0003 However, when this product is transported by a moving vehicle, etc., The rear cover moves up and down due to differences and unevenness, and the pivot shaft of the rear cover and other rear covers Not only will a large impact force be applied to the rotation support member, but in the worst case, the rear cover will This has the disadvantage that it may cause deformation of the bar body and damage to the supporting member. In order to prevent the rear cover from moving up and down unnecessarily, complicated fixing work is required and safety However, there is a concern that it will not be possible to smoothly transport the rotary tiller. It was something to do.

0004

[Problem that the idea aims to solve]

This invention was devised in view of the above-mentioned actual situation and to eliminate the drawbacks of the conventional ones. The purpose of this is to allow the rear cover to move up and down freely during tilling work. However, the rear cover can be easily fixed during transportation, eliminating unnecessary vertical movement. To prevent this from occurring, and also to ensure the strength of the rear cover body. The purpose of this project is to provide a rotary tiller that can perform the following tasks.

[0005]

[Means to solve the problem] In order to solve the problem, the technical means adopted by this invention is to A rotary cover that covers the tarry tilling section is provided, and both the left and right sides of the rotary cover are In a rotary tiller with a side cover attached to the side, the above rotary tiller - At the rear of the cover, a rear cover that can move up and down is attached, and the rear cover A reinforcing member is installed vertically along the left and right edges of the It is characterized in that the left and right side covers are removably connected.

[0006]

[Effect]

Therefore, according to the present invention, it is possible to easily prevent the rear cover from moving up and down during transportation. In addition, the strength of the rear cover body can be improved using reinforcing members. I can do that.

[0007]

【Example】

The configuration of the present invention will be described in detail with reference to an embodiment shown in the drawings. In Figures 1 and 2, 1 is a three-point link mechanism at the rear of the tractor (not shown). A rotary tiller mounted on the rotary tiller so that it can be raised and lowered through the rotary tiller. A rotary tiller is provided with a plurality of rotary claws 2, 2... on the front part of the working machine 1. The section 3 is installed parallel to the work machine frame 4 in the left-right direction, and the rotary - The rotary claws 2, 2 are installed in the chain case 5 attached to one side of the tiller 3. A rotary shaft (not shown) that pivotally supports ... and a drive shaft that is pivotally supported within the work machine frame 4 6 are connected via a chain 7, and the driving force transmitted from the gear case 8 The rotary claws 2, 2, . . . are configured to be rotated.

[0008] The chain case 5 is provided with an oil filler port 9 located near one end of the drive shaft 6. At the same time, a rubber cap 10 is fitted into the oil filler port 9. Also, above As shown in FIGS. 3 and 4, a fitting recess 11 is provided at the peripheral edge of the rubber cap 10. Further, an annular protrusion 12 is integrally formed toward the inside of the fitting recess 11. It is. Therefore, when the oil temperature in the chain case 5 rises and the internal pressure becomes large, Conventionally, as shown in FIG. 5, the inner wall 11a of the fitting recess 11 is formed in a flat shape. As a result, the rubber cap 10 is pushed outward by internal pressure, creating a gap A between it and the periphery of the oil filler port. However, in this embodiment, the annular protrusion 12 prevents the rubber cap from leaking. Even if the main body of the filler cap 10 is pushed outward, it remains sealed with the periphery of the oil filler port 9, preventing oil leakage. This can be prevented.

[0009] Support frames 13, 13 made of hollow pipes are located on the work machine frame 4. The frame 13 extends rearward at regular intervals and is movable up and down. A reinforcing pipe 14 is installed at an intermediate position between the supporting frames 13 and At the rear end of the bars 13, 13, there is a tool bar 16 with tail wheels 15, 15 mounted on both ends. It is suspended horizontally.

0010 Further, the upper part of the rotary tilling section 3 is covered by a rotary cover 17. Side covers 18 and 19 are vertically mounted on both sides of the rotary cover 17. In addition, a rear cover 2 is attached to the tip of the work machine frame 4. Support rails 21, 21, which pivot the 0 so that it can move up and down, are extended facing the rear of the aircraft. It is. Further, on the upper surface of the rear cover 20, reinforcing ribs 22a and 22b are provided. Plate-shaped reinforcing members 22c and 22d are provided along the vertical direction at predetermined intervals, respectively. ing.

[0011] As shown in FIG. 6, the reinforcing ribs 22a, 22b have hanging plates 23, 23. are fixed to the suspension plates 23, 23 and the rear end portions of the support rails 21, 21. A pressurizing spring 25 mechanism is inserted between the hanging brackets 24, 24 arranged in the The rear cover 20 is suspended, and the reinforcing members 22c and 22d are provided with vertically extending Bolt holes 26, 26, . . . are formed spaced apart from each other. On the other hand, the reinforcing members 22c and 22d are attached to the side covers 18 and 19. Mounting holes 27, 27 are bored facing the vertical movement locus.

0012 In the configuration as described above, the tilling work is completed and the rotary tiller 1 is moved. When transporting by vehicle, etc., lift the rear cover 20 and remove it as shown in Figure 7. Appropriate bolt holes 26, 26... of strong members 22c, 22d and side covers 18, 19 Align the mounting holes 27, 27 of the 9, the rear cover 20 is easily fixed to the side covers 19, 19. This ensures that the rear cover 20 does not move up and down due to vibrations and shocks while the moving vehicle is running. As a result, deformation and damage to the rear cover 20 can be prevented. In addition, the bolt holes 26, 26... provided in the reinforcing members 22c, 22d are As shown in FIG. 8, it can also be used for attaching extension covers 30, 30. I can do that.

[0013]

[Effect of the idea]

In short, the present invention provides a work machine frame with a rotary tiller that covers the rotary tiller. A tally cover is provided, and side covers are attached to both the left and right sides of the rotary cover. In the rotary tiller, there are upper and lower sections at the rear of the rotary cover. Attach a movable rear cover and place reinforcing members on the left and right edges of the rear cover. Along the bottom, the rear cover and left and right side covers can be easily engaged and detached via the reinforcing member. Since the rear cover is connected to the ground, the rear cover can be moved up and down during tilling work. However, the rear cover can be easily fixed during transportation, and it can be easily fixed on the road surface while driving. Due to the impact caused by the unnecessary vertical movement of the rear cover due to This not only prevents damage to the material, but also ensures the strength of the rear cover body. The rotary tiller can be transported safely and smoothly. This has extremely useful practical effects.
