Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a power crushing device.

(Prior technology) As shown in Figure 1, conventional power crushing equipment uses PTO
An input part A from the shaft, a power transmission cylinder B extending horizontally from the input part A, a side case C and a mounting body E provided on both sides of the power transmission cylinder B, and a side case C and a mounting body E. A crushing rotor D is provided in between, and the crushing rotor D has a mounting plate H of a bearing G of a shaft F that integrally projects upward from the bearing G, which is in contact with the mounting body E, and a bolt I and a nut J. It is a structure that is fixed with.

Further, in the conventionally known Japanese Patent Application Laid-Open No. 58-220602, the bearing member on the non-drive side of the rotating shaft of the earth crushing rotor has an inner bearing tube that supports a small diameter portion of the rotating shaft inside the mounting body; A structure is described in which the cover body is fixed to the outer surface of the inner bearing cylinder, and the cover body is fixed to the mounting body with bolts and nuts.

(Problem to be Solved by the Invention) In the former example, even if the crushing rotor D is exactly the same, several types of crushing rotor D must be produced using a device having the structure of the mounting body E on the main body side. It was annoying not to be able to do it.

That is, although several companies manufacture tractors, each company has its own structure even though they are the same size, so the structure of each company's mounting body E is slightly different. Therefore, the crushing rotor D that fits the tractor of Company A cannot be installed on the tractor of Company B, so the manufacturer manufactures the crushing rotor D that fits each tractor manufacturer's orders. ing.

Similarly, for the latter one described in Japanese Patent Application Laid-open No. 58-220602, several types of soil crushing rotors must be manufactured to match the tractors of each company. Furthermore, since the rotary shaft of the earth crushing rotor is supported only by the bearing portion inside the mounting body, there is a problem in strength.

The present invention provides a crushing rotor that is compatible with tractors of various manufacturers and has high durability.

(Means for Solving the Problem) Therefore, the present invention has an input part A to which an output shaft from a tractor is connected, a power transmission cylinder B extending from the input part A in the left and right lateral directions, and a power transmission cylinder B of the power transmission cylinder B. In one consisting of a side case C provided on one side, a mounting body 14 provided on the other side of the power transmission tube B, and a crushing rotor D provided between the side case C and the mounting body 14, The bearing member 18 on the non-drive side of the rotating shaft 1 of the crushing rotor D includes an inner bearing tube 5 that supports the small diameter portion 2 of the rotating shaft 1 that is inside the mounting body 14, and a small diameter portion 5 that supports the small diameter portion 2 of the rotating shaft 1 that is outside the mounting body 14. The outer bushing 17 that supports the part 2, the joint 15 that is clamped and fixed between the inner bushing 5 and the outer bushing 17 and abuts the mounting body 14, and the mounting hole of the mounting body 14 match. The power crushing device is composed of a mounting plate 11 having a joint hole 16, and the mounting plate 11 is separately formed with the joint hole 16 in a different position, so that it can be selectively used as appropriate. be.

(Example) To explain the example of the present invention using the diagram, the third
In the figure, 1 is the rotating shaft of the earth crushing rotor D, 2 is a small diameter part formed at the end thereof, a seal 3 and a bearing 4 are fitted to the back side of the small diameter part 2, and the outer periphery is connected to the inner bearing sleeve 5. surround it with The width 6 of the inner bearing sleeve 5 is as small as approximately 1/2 of the length 7 of the small diameter portion 2, and the outer end surface 8 of the inner bearing sleeve 5 is flat and has screw holes 9 in several places.
form.

After fitting the inner bearing cylinder 5 into the small diameter portion 2, the fitting hole 12 formed in the mounting plate 11 is fitted. The mounting plate 11 has a fitting hole 12 and a set screw 10.
In addition to the insertion hole 13, a joint portion 15 and a joint hole 16 are provided which are brought into contact with the mounting body 14 on the main body side.

In addition, as shown in FIGS. 8 and 9, a number of types of mounting plates 11 are manufactured to suit the mounting body E of each tractor, and one is selected and attached to the outer bearing sleeve 17 as a sandwich plate. Attach to.

(effect) Next, we will discuss the effect.

Since the present invention is as described above, a large number of crushing rotors D having the same structure are manufactured and, for example,
When an order is received from Company A, the mounting plates 11 that match the mounting body E of Company A are installed on the inner bearing sleeve 5 and the outer bearing sleeve 17.
During shipping, the product is sandwiched and tightened with set screws 10. When an order is received from Company RO, a mounting body 11 that matches the mounting body E of Company RO is fitted between the inner bearing sleeve 5 and the outer bearing sleeve 17.

(Effects) The present invention includes an input part A that connects the output shaft from a tractor, a power transmission tube B extending from the input part A in the left and right lateral directions, and a side case C provided on one side of the power transmission tube B. , a mounting body 14 provided on the other side of the power transmission cylinder B, and a crushing rotor D provided between the side case C and the mounting body 14, in which the rotation axis 1 of the crushing rotor D is
The non-drive side bearing member 18 includes an inner bearing sleeve 5 that supports the small diameter portion 2 of the rotating shaft 1 on the inside of the mounting body 14, and a small diameter portion 2 on the outside of the mounting body 14.
an outer bearing sleeve 17 that supports the inner bearing sleeve 5;
and a mounting plate 11 having a joint portion 15 that is clamped and fixed between the outer bearing sleeve 17 and abuts the mounting body 14, and a joint hole 16 that matches the mounting hole of the mounting body 14, and the mounting plate Reference numeral 11 is a power crushing device in which the mounting plates 11 with the joint holes 16 in different positions are separately formed and configured so that they can be selectively used as appropriate. Since the crushing rotor D can be formed and used selectively as appropriate, it is sufficient to produce only the crushed earth rotor D one after another, resulting in the effect that manufacturing is extremely easy.

Further, since the mounting plate 11 is clamped and fixed between the inner bearing sleeve 5 and the outer bearing sleeve 17, it is firmly mounted, and the mounting portion to the mounting body 14 on the main body side also has the effect of becoming robust.
