Abstract

The utility model belongs to the technical field of engineering-machinery control and relates to a double controller for a loader, which is provided with two handles (1), wherein the two handles (1) are symmetrically installed on a soleplate (8) of the controller, and the end heads of the two handles are respectively welded with a rocker arm (5); the two handles (1) for controlling a loader bucket to ascend, descend and overturn are respectively connected with corresponding soft shafts (7) through the rocker arms (5), and the other end of each soft shaft (7) is connected with a valve rod of a multipath valve of the loader to form a structure that the two handles swing to enable the rocker arms to make circular motion and operate the soft shafts to make pushing and pulling motion; each soft shaft (7) and each rocker arm (5) are vertically arranged; and the double controller is fixed in a cab through the soleplate (8), and the outer side of the double controller is provided with a protecting cover (6). Through the double controller for the loader, the problem that the soft shaft of the controller becomes heavy due to the entrance of dust in a severe working environment is eliminated, a driver is more comfortable to operate, the double controller has an attractive integral shape, the bottom space of the cab is enlarged, and the man-machine combination is more reasonable.

Description

Loader is with two controllers

Technical field

The utility model belongs to the engineering machinery control technology field, relates generally to a kind of loader with two controllers, is used for the control of loading shovel swing arm, tipping bucket banked direction control valves.

Background technology

At present, domestic construction machinery industry uses the change transmission direction in a large number, drives flexible axle, handles the controller of gearbox; It changes over the traditional structure that the sort of hard connecting rod connects, and has greatly improved convenience, the flexibility of control system general arrangement, has improved driving efficiency; What domestic large, medium and small loader was controlled banked direction control valves is the rocker arm controller mostly, and the operating principle of this kind controller is that the rocking arm that handlebar swing drive welds together with it moves in a circle, and does the push-and-pull campaign thereby drive the flexible axle inner core that links with it; Yet sort controller generally all be mounted in driver's cabin below, if under the situation of work under bad environment, be easy to make flexible axle to advance ash, flexible axle fixed-direction level backward, cause the flexible axle radius bend to diminish and send out heavy.

Summary of the invention

For solving the problems of the technologies described above, the utility model purpose is to propose a kind of loader with two controllers.

The utility model is finished the technical scheme that its invention task taked:

A kind of loader has two handles with two controllers, described two joint control system utensils, and described two handle symmetries are installed on the base plate of controller, and weld rocking arm respectively in the termination of described two handles; Described two handles that are used to control loading shovel lifting, tipping bucket link to each other with pairing flexible axle by rocking arm respectively, the valve rod of the other end of flexible axle and loader banked direction control valves links, and constitutes two handle swings and makes rocking arm move in a circle, handle the structure that flexible axle is done the push-and-pull campaign; Described flexible axle is vertical with rocking arm to be provided with; Described two controllers are fixed in the driver's cabin by base plate, and in its arranged outside guard shield are arranged.

On described base plate, each side weld a riser, and between two risers, respectively weld a fixed head that is used to prevent bottom deformation up and down, between described two risers, wear an axis; Described two handles are loaded on the two ends of axis respectively by bearing, make i.e. two the rocking arm symmetries installation of two handles at axis two ends.

A kind of loader that the utility model proposes is with two controllers, in its arranged outside guard shield is arranged, eliminated because of controller flexible axle under the work under bad environment and advanced the heavy problem of achromachia; rocking arm and flexible axle have been the vertical direction layout; reduced the arm of force relatively, steering force is light; made pilot control more comfortable, and have monnolithic case attractive in appearance, increased the driver's cabin bottom space, make man-machine combination more reasonable.

The specific embodiment

With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings:

As shown in Figure 1 and Figure 2, a kind of loader is with two controllers, described two joint control system utensils have two handles 1, described two handle 1 symmetries are installed on the base plate 8 of controller, and weld Rocker arm 5 respectively in the termination of described two handles, as shown in Figure 3, on described base plate 8, each side weld a

riser

9,12, and between two

risers

9,12, respectively weld a fixed head 10 that is used to prevent bottom deformation up and down, between described two

risers

9,12, wear an axis 2; Described two handles 1 are loaded on the two ends of axis 2 respectively by bearing 4, make i.e. two the Rocker arm 5 symmetries installation of two handles at axis two ends; Described two handles 1 that are used to control loading shovel lifting, tipping bucket link to each other with pairing flexible axle 7 by Rocker arm 5, fork-join head respectively, the other end of flexible axle 7 links by the valve rod of fork-join head and loader banked direction control valves, constitutes that two handles pendulum 1 is moving to make Rocker arm 5 move in a circle, handle the structure that flexible axle 7 is done the push-and-pull campaign; Described flexible axle 7 is vertical with Rocker arm 5 to be provided with; Described two controllers are fixed in the driver's cabin by base plate 8, and in its arranged outside guard shield 6 are arranged, and described passport 6 is fixed on the guard shield fixed head 11.

Claims

1. a loader is with two controllers, and described two joint control system utensils have two handles (1), and described two handles (1) symmetry is installed on the base plate (8) of controller, and welds rocking arm (5) respectively in the termination of described two handles; Described two handles (1) that are used to control loading shovel lifting, tipping bucket link to each other with pairing flexible axle (7) by rocking arm (5) respectively, the other end of flexible axle (7) and the valve rod of loader banked direction control valves link, and constitute two handle swings and make rocking arm move in a circle, handle the structure that flexible axle is done the push-and-pull campaign; It is characterized in that: described flexible axle (7) and the vertical setting of rocking arm (5); Described two controllers are fixed in the driver's cabin by base plate (8), and in its arranged outside guard shield (6) are arranged.
