[Prior Art]

 In the past, the cylindrical tubular anti-vibration rubber hole on the engine side was aligned with the hole formed on the U-shaped bracket on the vehicle frame side, and then the bolt was inserted into both. And fixedly connected.

[0003]

[Problems to be solved by the device]

 It was difficult to do bolt insertion work by suspending a heavy engine via a chain block, etc., and aligning both holes, making the engine installation work cumbersome. An object of the present invention is to make it easy to mount an engine by devising a structure for mounting the engine.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that the engine side is provided with a tubular bracket in a horizontal posture having a tubular anti-vibration rubber inside, and the body frame side is provided with the tubular bracket sandwiched from the side. An engine support structure is provided in which a U-shaped bracket to be attached is provided, and a bolt is inserted into the hole of the cylindrical anti-vibration rubber in the cylindrical bracket to fix and connect the cylindrical bracket and the U-shaped bracket. For inserting the bolts inserted into the holes of the tubular anti-vibration rubber inside the tubular bracket on the engine side from one side into one of the U-shaped brackets facing the body frame side. In addition to forming a recess in the horizontal direction, on the other hand, a recess is formed obliquely upward for inserting the bolt in the vertical direction.

[0005]

[Action]

 As shown in FIGS. 1 and 2, when the engine 1 is mounted on the vehicle body frame 4, the bolt 6 is inserted into the hole of the tubular vibration-proof rubber 2 in the tubular bracket 3 on the engine 1 side. , The cylindrical bracket 3 on the engine 1 side is laterally inserted into one of the U-shaped brackets 5A arranged to face the body frame 4 so that the bolts 6 are engaged with the recesses 5a, and the other U-shaped bracket The tubular bracket 3 on the engine 1 side is dropped into the bracket 5B from above and the bolt 6 is engaged with the recess 5b to fix and connect the bolt 6 thereto.

[0006]

[Effect of the device]

 As a result of the above configuration, it is not necessary to perform precise centering of holes as in the conventional case, and the engine suspended through a chain block or the like can be easily mounted by sliding it left / right or up / down. ..

[0007]

【Example】

 Hereinafter, an embodiment of the present invention will be described with respect to an engine mounting structure of a combine. As shown in FIG. 1, tubular brackets 3 having tubular anti-vibration rubbers 2 burned and fixed inside are fixedly connected at four locations on the lower part of the engine 1, and their axial centers are fixedly connected in the left-right direction of the machine body. Four U-shaped brackets 5 for sandwiching the tubular bracket 3 from the lateral side are fixedly connected to the body frame 4, and the U-shaped brackets 5A arranged to face the body frame 4 in the front-rear direction. As shown in FIG. 3, the bolt 6 inserted into the hole 2a of the tubular vibration-damping rubber 2 is attached to the front bracket 5A of 5B in a horizontal direction as shown in FIG. The recess 5a is formed, and the rear bracket 5B is formed with an obliquely upward recess 5b for inserting the bolt 6 inserted into the hole 2a of the tubular vibration-proof rubber 2 from above and below. is there. The tubular bracket 3 on the engine side engaged with the recesses 5a, 5b of the U-shaped brackets 5A, 5B on the vehicle body frame 4 side via the bolt 6 is a bolt 6 inserted into the tubular anti-vibration rubber 2. Is fastened and fixedly connected to the U-shaped bracket 5 on the body frame 4 side.

As shown in FIG. 4, a cutting pretreatment device is provided in a power transmission pulley 8 attached to a flywheel 7 of the engine 1 for transmitting power from the engine 1 to a traveling mission and a threshing device. A hydraulic pump 9 for a hydraulic cylinder for driving up and down is mounted via a bearing 10. The rotary shaft 9a of the hydraulic pump 10 is connected to the flywheel 7 so that power can be transmitted, and the case of the hydraulic pump 9 is connected. The thing is supported by the vehicle body frame 4 via the stay 11. As shown in FIG. 5, the power from the engine 1 is transmitted to the belt continuously variable transmission 14 in the traveling mission case 13 via the belt transmission 12, and then transmitted to the gear transmission 15 in the case. That is, the belt continuously variable transmission 14 that is originally mounted on the outer upper portion of the split transmission case in which the gear transmission 15 is internally mounted via the split transmission case is provided with the gear transmission. The device 15 is installed inside the traveling mission case 13 so that the device can also be used as a case. The traveling mission case 13 is divided into three parts to facilitate production.

[Other Embodiments] As shown in FIG. 6, when mounting the engine 1 on the vehicle body frame 4, the lower piece of the U-shaped bracket 5A at the front portion is lengthened to form the receiving portion 5a '. It is also possible to form a concave portion 5b in the U-shaped bracket 5B at the rear part in the opposite direction to the above so that one end side of the engine 1 is received by the receiving portion 5a 'and is slidably attached.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
