Description
Technical field
The utility model relates to automatic hay mower, is specifically related to the mowing arrangement for adjusting height of automatic hay mower.
Background technology
In order to satisfy the requirement of user to difference mowing height, most of common mowers all are equipped with the mowing arrangement for adjusting height, and main implementation has two kinds.For common walk-behind greensmower; Adopt the eccentric interlock road wheel of installing to realize mostly; And for automatic hay mower, then mainly realize through the height of regulating blade or mowing motor, wherein regulate the mode of blade height owing to need specific purpose tool; And difficulty is big, has problem such as potential safety hazard and is difficult for being accepted by the user.
The China utility model patent CN201491509U (patent No.: 200920196103.4) disclose a kind of mowing height adjusting structure of intelligent grass-removing, adopted screw thread to regulate height, regulated easy and can realize stepless stably height change; The benefit of this structure is must not use any specific purpose tool; Directly from just can realize the mowing adjusting of height of the top adjusting nut of machine, but it also comes with some shortcomings, and mowing motor and blade are to fix through adjusting nut and the internal thread interlock that is installed on the chassis; Because it is not fixing fully; In blade was mowed the course of work for a long time, owing to receive the impact of mowing reaction force, the chassis was rocked very severe; Noise is big, and internal thread and very easy wearing and tearing of nut and damage.
The utility model content
The utility model technical problem to be solved is that severity is rocked on the mowing arrangement for adjusting height chassis that solves mower, noise is big, and the problem of internal thread and very easy wearing and tearing of nut and damage.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted provides a kind of mowing arrangement for adjusting height of automatic hay mower; Comprise left and right self-locking type air spring; The crossbeam and being used to that is used for fixing the mowing motor of automatic hay mower is regulated the depression bar of the height of mowing; The lower end of the cylinder body of said left and right self-locking type air spring is fixed on the chassis of automatic hay mower, and said crossbeam is fixed on the tailpiece of the piston rod of said left and right self-locking type air spring, and said left and right self-locking type air spring extend upwardly out said crossbeam from lock; Said depression bar is slidingly arranged on the said crossbeam, and the bottom surface is pressed in said on the end face of lock.
In such scheme, the left and right two ends of the end face of said crossbeam are respectively equipped with lead, and said pressing plate is provided with and the suitable through hole of said lead, and said lead is inserted in the said through hole.
The utility model; Fixedly the crossbeam of mowing motor is fixed on the chassis through left and right self-locking type air spring, and this has just overcome the problem that the mowing motor rocks in the course of the work, simultaneously; Can realize the stepless up and down mobile of motor of mowing like a cork through depression bar; Thereby it is drive the mowing blade and realize the step-less adjustment highly of mowing, need not any specific purpose tool, and safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Sketch map when Fig. 2 lifts for mowing arrangement for adjusting height shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the mowing arrangement for adjusting height of the automatic hay mower that the utility model provides comprises left and right self-locking type air spring 4,5, and the crossbeam 7 and being used to that is used for fixing the mowing motor 3 of automatic hay mower is regulated the depression bar 8 of the height of mowing.
The lower end of the cylinder body of left and right self-locking type air spring 4,5 is fixed on the chassis 1 of automatic hay mower; Crossbeam 7 is fixed on the tailpiece of the piston rod of left and right self-locking type air spring 4,5; And left and right self-locking type air spring 4,5 upwards stretch out crossbeam 7 from lock 6, depression bar 8 be arranged on crossbeam 7 directly over, the left and right two ends of the end face of crossbeam 7 are respectively equipped with lead; Pressing plate 8 is provided with the through hole suitable with lead; Thereby lead is inserted into depression bar 8 is slidingly arranged on the crossbeam 7, and the bottom surface of depression bar 8 be pressed in left and right self-locking type air spring 4,5 on lock, it is movable that depression bar 8 can easy on and off on lead.
The utility model had both overcome the loaded down with trivial details and dangerous problem of direct adjusting blade, had also overcome problems such as plain nut and internal thread interlock mode are existing fixes insufficient, mowing mechanism and rock severity, and noise is big simultaneously.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
