Cultivator Excavator {omitted}

The present invention relates to a cultivator excavator, and more particularly, to a cultivator excavator that can be used by mounting an excavator assembly to an existing cultivator.

In general, excavators are capable of moving various drives and actuators at the output of the engine. Therefore, the existing excavator must be fully equipped with the above conditions to fulfill the function as an excavator, and the cost is high when manufacturing a product having the function as described above is sold at a high price. Since the cultivator for the cultivator of the present invention is directly obtained from the engine unit and the driving unit, the cultivator main body 1 does not need to be manufactured separately, and only an assembly required for the excavation work may be additionally installed, thereby providing a very low price. Until now, the tiller attachment excavator is installed on the trailer with the boom position on the rear of the tiller main body (1), so that the operator must turn around to operate the excavation, and when the excavator is moved, the inconvenience that the operator must turn again when moving Excavation work without the outriggers (22) and (24) does not allow the cultivator body (1) and the trailer to be unbalanced, threatening worker safety. Diversion and excavation work are not allowed.

This cultivator excavator is installed on the right side of the cultivator main body 1 when the position of the boom pillar 9 is viewed from the operator's perspective, as shown in FIG. 4, so that the front field is good and the operator can move easily during the excavation work, and the appearance is compact. It is easy to change direction and excavation work in narrow space. In addition, the front and rear outriggers (22, 24) were installed for safe excavation work.

An object of the present invention is to use an excavator assembly mounted on an existing cultivator and to smoothly operate each element of the excavator by using the engine power and driving power of the cultivator. The invention for the cultivator excavator is similar in operation and function when compared to a general compact excavator, and as shown in FIG. 4, the boom column 9 is installed on the right side of the cultivator body 1 when viewed from the operator, The focus was placed on increasing the field of view and the working radius of the cylinder. The operating lever for the cylinder 6 was mounted on the auxiliary handle 47 of the cultivator so that the operator could conveniently operate with the right posture. The front and rear outriggers 22 and 24 are mainly used to balance the cultivator main body 1 during the excavation work, and the front outrigger 22 is based on the operator's standard as indicated by reference numeral 22 'in FIG. It can be extended to the left and right, so that the cultivator main body 1 does not tilt or lose balance even when the position of the basket 15 works in a bad condition. In addition, the front outrigger 22 has the advantage that can also play a role of scraping or moving the soil on the ground at the same time. The cultivator for the cultivator according to the present invention applies the driving force of the rear wheel 17 for driving the cultivator. The driven front wheel 18 is driven by the small chain sprocket 40 and 41 and the power transmission chain 19. It is a four-wheel drive that can move simultaneously with 17) and can move smoothly on the bad ground. The cultivator for the cultivator of the present invention connected the trailer body 28 with the wheels with the chuck 43 attached to the cultivator to reduce the fatigue of the operator during the long time travel and excavation work, and the saddle 33 on the trailer body 28. By installing it, the worker can work in a comfortable posture, and the height of the saddle 33 can be used by fixing the saddle height adjusting pin 34 so as to fit the working condition and the physical condition. The trailer springs 32 were mounted on the trailer wheels 31 to protect them from damage. Conventional tillers are driven by the steering clutch lever 44 for turning the steering wheels, because the rear wheels 17, which are a pair of left and right driving wheels, are supported by two points on the ground. One wheel of the rear wheel 17 for the dragon was stopped and the other wheel was rotated so that the direction was possible to change. The cultivator for the cultivator of the present invention carries more weight on the driven front wheel 18 than the driving rear wheel 17 due to the weight of the excavator assembly, and forms four-point support on the ground, so that the turning radius is narrower. Since it is difficult to install the auxiliary wheel 20 for rotation and cushioning in the front center of the cultivator main body 1 as shown in FIG. 6, and the front wheel 18 for driven by the auxiliary wheel cylinder 21 for rotation and cushioning is When lifted from the ground and at the same time the auxiliary wheel 20 for rotation and cushioning contact with the ground forms a three-point support on the ground together with the driving rear wheel 17, the steering clutch lever 44 for turning the steering steering One wheel of the rear wheel 17 for driving is stopped and the other wheel rotates, and at the same time, the tiller main body is rotated by the rotation of the auxiliary wheel 20 for rotation and cushion installed in the front center of the tiller main body 1. 1) enabled a change of direction with a narrow turning radius.
