リンク式に接続されるものに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a work vehicle, in particular a tractor seatbelt, which has a loading device disposed at the center of the front, and a lift supported at the front by its lifting arm. A cylinder, a tilting crane, and a quick change device at the front end are engaged, and the device is connected in a linked manner via a tilting rod to a tilting crane operated by the tilting cylinder.
〔従来の技術〕
この種のトラクターシャベルはずっと以前より公知であ
って旋回可能な後輪と、旋回不能な前輪を備え、作業中
に安定性を確保するようになっている。BACKGROUND OF THE INVENTION Tractor shovels of this type have been known for a long time and are equipped with swivelable rear wheels and non-swivelable front wheels to ensure stability during operation.
〔発明が解決しようとする課題]
本発明の目的は同種作業車両の場合に40’以上の最大
回転角を有する旋回可能前輪を許容し、その際装填装置

車両の傾斜安定性が損われないようになった装填装置を
提供することである。[Problem to be Solved by the Invention] The object of the invention is to allow, in the case of similar work vehicles, a pivotable front wheel with a maximum rotation angle of 40' or more, in which case the external force introduced via the loading device prevents the motor from moving. To provide a loading device in which the tilting stability of a vehicle around a transverse axis is not impaired.
(課題を解決するための手段)
本発明の場合、最初に述べた種類の装置に関する上記目
的は以下の如くして実現される。Means for Solving the Problems In the case of the present invention, the above-mentioned object with respect to a device of the type mentioned at the beginning is achieved as follows.
上昇アームの車両側端部が通路状の前方方向に開いた前
部の凹所内へ係合し、
傾斜シリンダもまた前部に係止され、
上昇アームが狭幅の構成部材として構成され、上部から

イックチェンジ装置だけが車輸聞スペースを越えて下部
方向にわずかに突出するよう構成される。The vehicle-side end of the lifting arm engages in a channel-like forwardly open front recess, the tilting cylinder is also locked in the front, and the lifting arm is configured as a narrow component, with the upper When viewed from the side, the quick change device finds a space at the maximum sunken position between the front wheels, so that when viewed from the side, only the quick change device slightly protrudes downward beyond the vehicle space. .

て特に小さいように確保される。すなわち、これには上
野アームが車輪間スペース内へ進入するだけでなくトラ
クターシャベルの前部の凹所へそれが深く旋回すること
が寄与する。In the case of a similar construction of the 1-Lactor Siber, the lifting arm is ensured to be particularly small with respect to the tilting moments that occur about the vehicle transverse axis. This is achieved not only by the entry of the Ueno arm into the space between the wheels, but also by its deep pivoting into the recess at the front of the tractor shovel.
上昇アームは本発明の場合、最大に沈下したとぎでもそ

あいおもりの位置を低く設計することが可能になる。上
昇アームを深い所に配置−することによって更に運転者
のために作業場の最適な展望と上昇作業上の自由な視野
が得られる。In the case of the invention, the lifting arm is constructed in such a way that even in the case of a maximum depression it finds a void in the interwheel space in the case of the front wheels which themselves have a large maximum angle of rotation. In this position, the tractor shovel is just in front of the front wheels, so
The tilting stability under load is improved or the counterweight position can be designed lower. The deep positioning of the lifting arm also provides the operator with an optimal view of the work area and a free field of view for the lifting operation.

1゛ることができる。For reasons of space, another inventive proposal is to swivel the cylinder and the tilting cylinder to the lower front part of the lifting arm so that the lifting arm has a side blade projecting towards the vehicle;
It serves this purpose that it covers both cylinders in the forward direction. This measure results in a construction of the hydraulic cylinder that is particularly protected against the working material. In terms of cross section, a case profile with blades attached to the sides, or a U-profile is preferred for the lifting arm. This protected configuration of the hydraulic cylinder can be further improved in that at least the tilting cylinder extends inside the lifting arm. In that case, the two cylinders can be pivotably arranged within a plane that is closely located relative to each other.

可能に受取られるようになっている点である。Similarly, for reasons of space, the quick-change device has a particularly simple design. The device has two laterally projecting connection pivots on each connection side, an upper receiving pivot for the shovel catch and a lower hydraulically axially retractable locking pivot. A simple feature with respect to known quick-change devices is that the locking pivots are each configured to be axially movable into the central bore of the side support pivot of the lifting arm, and the support pivots are arranged in a corresponding bushing of the quick-change device. The point is that it can be received in a rotatable manner.

is pivoted around a horizontal axis 5 inside a passage-like recess 6 of the front part 1 and is locked therein. A quick change device 7 shown in the top view of FIG. 2 is attached to the front end of the lifting arm 4 together with a receiving pivot 8 for a shovel catch projecting from the side. In the top view of FIG. 2, the swivelable front wheel 9 of the tractor shovel is shown in a straight position. The ground front wheel is indicated by a dashed line 10, and the left front wheel is indicated by a dotted line 11 at a position having the maximum turning angle. In all wheel positions, the lifting arm easily finds space in the interwheel space, with only the quick change device with its lower end 12 latched to the front end of the lifting arm 4 protruding slightly beyond the interwheel space. You can see right away. In FIG. 1, the right front wheel 9 is depicted in the position indicated by the dash-dotted line 10 in FIG.

At the lower end 12, the quick change device is provided with an O-sock pivot 24 which is moved forward and backward in the axial direction by hydraulic pressure, and the pivot 24 engages in a corresponding hole in an eye 25 provided on the lower side of the tractor shovel. The eye 25 and the shovel main 11 joint 22 are arranged on opposing stems 26 on the rear side of the novel 23.

下端部の旋回シレフト28が係止される。From the sectional view of FIG. 5, it can be seen that the receiving pivot 8 for the shovel 1-V gear is constituted by an end portion of a continuous shaft 27 projecting to the opposite side of the quick change device 7. The shaft 27 is mounted in a corresponding bore in the upper end 20 of the quick-change device 7 so as to prevent rotation and axial movement. A pivot shaft 28 at the lower end of the inclined rod 21 is locked at the center of the shaft.
