Abstract

The utility model relates to an assistor of an agricultural tool of quick mounting of a tractor, which comprises a floorstand, a transverse beam, a hanging pin, a front riser, a back riser with a long hole, a hook, a locking lever, etc., wherein, the front riser and the back riser with the long hole are fixed on the upper end of the floorstand. The transverse beam is fixed to the lower end of the floorstand. The hanging pin is fixed to the lower end of the floorstand. The hook and the locking lever are arranged on both ends of the transverse beam. The utility model uses the method that the front riser and the hanging pin are connected with the tractor. The agricultural tool is attached on the back riser with the long hole and the hook, and the attaching function is achieved.

Description

Quick mounting frame for farm tools

The utility model belongs to a kind of agricultural machinery, particularly relates to the servicing unit that a kind of tractor articulates farm implements fast.

China does not almost use the quick hitch of farm implements at present, and the suspension parameter that hangs farm implements is also nonstandard, has hindered the penetration and promotion of this device.At present the only several routine hanging devices that use all are hanging devices of design according to the employed farm implements of own unit and voluntarily, all exist shortcomings such as interchangeability is poor, efficient is low, service precision is low.

The purpose of this utility model provides and a kind ofly is applicable to that various farm implements hang fast, and interchangeability reaches the high quick implement hanging frame of service precision by force.

Major technique content of the present utility model is to comprise stand, crossbeam, hang pin, front vertical plate, wherein, crossbeam is fixed on the lower end of stand, hang the outside of selling the lower end that is fixed on stand, front vertical plate is fixed on the upper end of stand, it is characterized in that two hook rack are enclosed within the place, two ends of crossbeam, two tightening devices are installed on the hook rack, two hooks are separately fixed on two hook rack, securing rod is installed on the hook with bearing pin, one end of securing rod is connected with hook rack with spring, and the securing rod alignment pin is installed on the hook, and belt length hole back vertical plate is fixed on the upper end of stand.

When the utility model used, the utility model integral body was installed on the tractor by front vertical plate and suspension pin, loosens the tightening device again hook rack and hook etc. is slided into the position that is fit to the farm implements size, again with the tightening of tightening device; Following hitch point with farm implements is suspended on the hook again, and the upper connecting rod length of adjusting tractor again is suspended in the slotted hole of belt length hole back vertical plate the last hitch point of farm implements.

Advantage of the present utility model is to be applicable to articulating fast of various large-scale farm implements that interchangeability is strong, the service precision height.

Fig. 1, Fig. 2 are two views of the present utility model,

Fig. 3 is the structure chart of hook part of the present utility model.

The utility model such as Fig. 1, Fig. 2, shown in Figure 3, by band slotted hole back vertical plate 1, front vertical plate 2, stand 3, hang pin 4, hook rack 5, crossbeam 6, spring 7, securing rod 8, hook 9, bearing pin 10, securing rod alignment pin 11, locking apparatus 12 forms, wherein, crossbeam 6 is fixed on the lower end of stand 3, suspension pin 4 is fixed on the outside of the lower end of stand 3, front vertical plate 2 is fixed on the upper end of stand 3, be fixed on the upper end of stand 3 with slotted hole back vertical plate 1, two hook rack 5 are enclosed within the place, two ends of crossbeam 6, two locking apparatus 12 are installed on the hook rack 5, two hooks 9 are separately fixed on two hook rack 5, securing rod 8 usefulness bearing pins 10 are installed on the hook 9, securing rod 8 usefulness bearing pins 10 are installed on the hook 9, and an end of securing rod 8 is connected with hook rack 5 with spring 7, on the hook 9 securing rod alignment pin 11 are installed.

An embodiment of the present utility model is as follows:

Arched frames are adopted in stand 3, and its lower end and crossbeam 6 are welded together, and burn-on two in the outside of the lower end of arched frame and to hang pin 4, and arched frame top is welded with the belt length hole back vertical plate 1 that can connect farm implements, to adapt to the variation of different farm implements column height.

Two hook rack 5 are housed at the two ends of crossbeam 6, hook 9 is welded on the hook rack 5, the spring 7 of securing rod 8 and stretchy securing rod 8 is housed with bearing pin 10 on the hook 9, make securing rod 8 under the tension of spring 7, fasten the following suspension pin of farm implements, link up with 9 traction to prevent to go here and there or break away from, securing rod 8 can rotate around bearing pin 10, also has a hole on the hook 9, when taking farm implements, with bearing pin 10 securing rod 8 is stuck in can make farm implements following suspension pin from linking up with 9 positions of taking.

Hook 9 can slide on crossbeam 6, chooses behind the position with 12 tightenings of tightening device, and string is moving when preventing work.

Before using the utility model to articulate farm implements, at first this device should be articulated on the hitch of tractor, the suspension pin 4 on this device and the lower link of tractor are connected, the front vertical plate 2 on top and the upper connecting rod of tractor are connected, also the spacing of two hooks 9 should be adjusted on the just in time identical position and and be fixed on the crossbeam 69 pairs of arched frame symmetries of two hooks with tightening device 12 with twice suspension pin spacing dimensions of farm implements.

Tangle two of farm implements with two hooks 9 then and hang pin down, hang up properly the back driver and get off and adjust the upper connecting rod length of tractor, make the corresponding also connection of last hitch point of slotted hole with the farm implements of belt length hole back vertical plate 1.

For adapting to frequently articulating of the different large-scale farm implements that hang sizes, on crossbeam 6, can make calibration, make the spacing conversion of hook 9 accurate rapidly.
