クタ専用に製造していた。BACKGROUND OF THE INVENTION Traditionally, agricultural tractors are manufactured by multiple agricultural tractor manufacturers. The drive shafts of manufactured agricultural tractors are not standardized, so they differ slightly from manufacturer to manufacturer. Therefore, when installing a crushing wheel, only its shaft structure has been manufactured specifically for each agricultural tractor.
（発明が解決しようとする課題）
砕土輪の軸部構造のみを、それぞれの農用トラ
クタ専用に製造することは、コストを高くする。(Problems to be Solved by the Invention) Manufacturing only the shaft structure of the crushing wheel exclusively for each agricultural tractor increases costs.

したものである。(Means for Solving the Problems) Accordingly, the present invention provides a system that fits into the drive shaft 2 of a plurality of types of agricultural tractors 1 whose drive shafts 2 have different outer diameters, and whose outer diameters are the same but whose inner diameters are the same. The drive shaft 2 is composed of a plurality of types of extension shafts 4 that are fitted together, and a crushing wheel 3 that is detachably fitted to the outer periphery of the extension shaft 4, and the extension shaft 4 has a keyway 13 on the agricultural tractor 1 side. The attachment part 4a for the anti-agricultural tractor 1 side is an extension part 4b consisting of a simple hollow pipe.
This is a structure for attaching a crushing wheel to an agricultural tractor.

なるのである。(Example) To explain with reference to the drawings, FIG. 1 is a diagram of a known example, where 1 is a tractor and 2 is a drive shaft protruding to the left and right sides thereof. A shaft cylinder 4' for attachment is fixed to the center of the crushing wheel 3 by a stay 5. Then, hold the soil crushing wheel 3 in your hand and insert the tip of the shaft cylinder 4' into the drive shaft 2.
The crushing wheel 3 is fixed by fitting it snugly onto the outside of the drive shaft 2, inserting a set screw 6 longer than the outer end, and screwing it into the screw hole formed at the center of the drive shaft 2. In this case, the external shape of the drive shaft 2 is not the same, and each company has its own structure, so the crushing wheel 3 is dedicated to it.
第２図以降は本考案のもので、各社のそれぞれ

外周に固定する。 Figure 2 and subsequent figures are of the present invention, and the drive shaft 2 of each manufacturer's tractor is provided with an extension shaft 4 that fits snugly on the outside of the drive shaft 2.
The external shape of each tractor is formed to have the same dimensions. A mounting plate 8 having a through hole 12 is provided at right angles on the base side (inside) of the extension shaft 4.
A lid 14 is placed on the outer end, and a through hole 15 is provided in the center of the lid 14.
is formed, and the set screw 6 is inserted through the through hole 15.
A threaded portion 16 formed at the tip of the set screw 6 is screwed into a screw hole 17 formed at the tip of the drive shaft 2, and the extension shaft 4 is fixed to the outer periphery of the drive shaft 2 by tightening.
しかして、別途砕土輪３を形成し、砕土輪３の
ステイ５には軸筒７を取付けるが、軸筒７の内径
寸法は前記駆動軸２に嵌合するものではなく、前
記延長軸４の外周に嵌合するように形成する。 Therefore, a crushing wheel 3 is formed separately, and a shaft cylinder 7 is attached to the stay 5 of the crushing wheel 3, but the inner diameter dimension of the shaft cylinder 7 is not such that it fits on the drive shaft 2, but on the extension shaft 4. Formed to fit around the outer periphery.
第３図の実施例では、左側のステイ５は軸筒７

取付けてよい。 In the embodiment shown in FIG. 3, the left stay 5 is connected to the shaft cylinder 7.
Although the figure shows a state in which the support plate 10 is fixed to the stay 5, in order to facilitate assembly, the through holes 11 formed in the stay 5 are made to have different diameter holes to prevent the screws from turning. be. Therefore, when holes of different diameters are not formed, the stay 5 may be attached directly to the shaft tube 7.

indicates a keyway.
（作用） 次に作用を述べる。(effect) Next, we will discuss the effect.
砕土輪業者は、前記軸筒７付きの砕土輪３を別

る。 The crushing wheel manufacturer separately manufactures a large number of crushing wheels 3 with the shaft tube 7, but does not manufacture the extension shaft 4 at that stage. When we receive an order for crushing wheels from a specific manufacturer, we manufacture extension shafts 4 that fit the unique drive shaft 2 of that tractor for the number of units ordered, and we then attach these extension shafts 4 to the shaft cylinders 7 of the crushing wheels 3 that have been manufactured in advance. All you have to do is fit it in, secure it with the setscrew 9, and ship it.

先部の取付部４ａのみが駆動軸２の外周に係合す

形成した構造にすると、その製作は極めて面倒で
あるが、本考案は取付部４ａにのみキー溝１３を
形成し、その余は単なる中空パイプの延長部４ｂ
としたので極めて安価に生産できる。 Therefore, when an order is received, only the extension shaft 4 needs to be manufactured. In this case, only the mounting portion 4a at the tip of the extension shaft 4 engages with the outer periphery of the drive shaft 2, and the remaining portion does not engage with the drive shaft 2. Therefore, if a structure in which the keyway 13 is formed along the entire length of the extension shaft 4 is made, manufacturing thereof is extremely troublesome, but in the present invention, the keyway 13 is formed only in the attachment part 4a, and the rest is simply a hollow pipe. extension part 4b of
Therefore, it can be produced extremely cheaply.
また、極めて短時間で製造できる。 Moreover, it can be manufactured in an extremely short time.
従来公知の砕土輪３は、各社ごとに構造の異な
る軸筒７としなくてはならないので、メーカー別
生産となり不経済であつた。 The conventionally known crushing wheel 3 has to have a shaft tube 7 with a different structure for each company, which is uneconomical because it has to be produced by each manufacturer.

になる。 However, the present invention provides a plurality of types of agricultural tractors 1 with drive shafts 2 having different outer diameters, and a plurality of types of extension shafts 4 having the same outer diameter but an inner diameter fitted to the drive shafts 2 of the respective agricultural tractors 1. and a crushing wheel 3 that is removably fitted to the outer periphery of the extension shaft 4, and the agricultural tractor 1 side of the extension shaft 4 has a keyway 13 at the attachment part 4a for the drive shaft 2, and the agricultural tractor 1 side has a keyway 13. The first side is formed into an extension 4b made of a simple hollow pipe and has a structure for attaching the crushing wheel of an agricultural tractor. Since it is only necessary to fit the crushed earth ring 3 which is already provided, the manufacturing effort is significantly simplified.
