Abstract
The utility model discloses a mechanism for adjusting the wheel track of an agricultural walking machine. The mechanism for adjusting the wheel track of the agricultural walking machine is convenient to use and adjust and good in adaptability. The mechanism for adjusting the wheel track of the agricultural walking machine comprises a main machine frame and walking wheels. Two connecting rods are downwards hinged to a horizontal cross beam of the main machine frame in a bilateral-symmetry mode. A hydraulic oil cylinder is arranged between the upper hinged point of one connecting rod and the other connecting rod in an inclined and hinged mode mode. Independent walking wheel carriers are hinged to the lower ends of the two connecting rods in parallel. The two connecting rods, the hydraulic oil cylinder and the walking wheel carriers form a left four-rod swing mechanism and a right four-rod swing mechanism respectively, wherein the two four-rod swing mechanisms are parallel. The walking wheels are installed on the walking wheel carriers in a rotatable mode. The mechanism for adjusting the wheel track of the agricultural walking machine is suitable for achieving wheel track adjustment by being arranged on the agricultural walking machine.
Description
Technical field
The utility model belongs to agricultural walking machine mechanism, more particularly, relates to a kind of agricultural walking machine wheelspan adjusting mechanism.
Background technology
China's agricultural generally adopts ridge culture planting pattern, in order to make agricultural walking machine driving stability, and direction accurate positioning, field management in mid-term no seedling injury, requires agricultural walking machine must adapt to ridge culture technology mode, and the tire of agricultural walking machine is aimed at furrow walking.Along with the fast development of agricultural modernization, very large for Different Crop, different planting area China ridge culture planting patterns of change, there are different ridge culture line-spacings, even adjacent plot ridge culture line-spacing is also different.This just requires agricultural walking machine wheelspan adjustable; the current design plan for agricultural walking machine wheelspan adjusting mechanism; general is all the horizontal extension adjustable mechanism that adopts tire support bracket, need to shut down jack-up support bracket and make tire liftoff reach non-bearing state when adjustment, unclamps pedestal fastener; pedestal is retractable to the position of requirement; operation is wasted time and energy, pretty troublesome, also inconvenient; and can not adapt in operation process the requirement of the direct quick adjusting wheelspan in field.
Summary of the invention
The purpose of this utility model is for the problems referred to above that exist, and provides a kind of Tiao of use perfect square Bian ﹑ comformability good agricultural walking machine wheelspan adjusting mechanism.
For achieving the above object, the utility model adopts following technical proposals: agricultural walking machine wheelspan adjusting mechanism of the present utility model, comprise mainframe, road wheel, symmetrically on the horizontal gird of this mainframe hinged be respectively provided with two connecting rods downwards, the hinged hydraulic ram that arranges therein tilts between the upper link point of a connecting rod and another connecting rod, this parallel hinged setting in two connecting rod lower ends wheel carrier of independently walking, make this two connecting rods, with a hydraulic ram, walking wheel carrier forms respectively two the parallel four-bar swinging gear in left and right, this walking wheel carrier is rotatably mounted road wheel.
Adopt after technique scheme, the beneficial effect that the agricultural walking machine wheelspan adjusting mechanism that the utility model provides has is:
Because the utility model adopts two of the left and right parallel four-bar swinging gear that is provided with hydraulic ram, for Different Crop, the different row spacing cropping pattern of different planting area, can stretch and make two of left and right parallel four-bar horizontal hunting simultaneously by hydraulic ram whenever and wherever possible, this walking wheel carrier laterally inwardly narrows thereupon or outwards broadens, and reaches the object of adjusting road wheel distance.So, obtained using the good effect of Tiao perfect square Bian ﹑ comformability.
Brief description of the drawings
Accompanying drawing 1 is the organigram of the agricultural walking machine wheelspan of the utility model adjusting mechanism.
In figure: mainframe 1; Connecting rod 2; Hydraulic ram 3; Walking wheel carrier 4; Road wheel 5.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, provide the organigram of the agricultural walking machine wheelspan of the utility model adjusting mechanism, comprise mainframe 1, road wheel 5, symmetrically on the horizontal gird of this mainframe 1 hinged be respectively provided with two connecting rods 2 downwards, the hinged hydraulic ram 3 that arranges therein tilts between the upper link point of a connecting rod 2 and another connecting rod 2, these two connecting rods, 2 parallel hinged settings in lower end wheel carrier 4 of independently walking, make this two connecting rods 2, with a hydraulic ram 3, walking wheel carrier 4 forms respectively two the parallel four-bar swinging gear in left and right, this walking wheel carrier 4 is rotatably mounted road wheel 5.
When agricultural walking machine wheelspan adjusting mechanism work, as shown in Figure 1, the agricultural walking facility of installing and adjusting mechanism can change and carry out wheelspan adjustment according to crop-planting row spacing whenever and wherever possible, and the work tool tire that makes to walk remains along furrow advances.In the time that row spacing diminishes, manipulation HYDRAULIC CONTROL SYSTEM hydraulic ram 3 shortens, and drives two parallel inside swings of connecting rod 2, and left and right two parallelogram lindages of two walking wheel carrier 4 following lefts are inwardly swung, and wheelspan and the row spacing diminishing are adapted; Otherwise, in the time that row spacing becomes large, by reverse operating, wheelspan and the row spacing diminishing are adapted.Operating process is time saving and energy saving, very convenient, stronger for the comformability of Different Crop, the different row spacing cropping patterns of zones of different.
In the time of the end of job or field transfer, can also obtain by above-mentioned method of adjustment the wheelspan of suitable transportation request.
The utility model is applicable to be arranged on realizes wheelspan adjustment on agricultural walking machine.
Claims (1)
1. an agricultural walking machine wheelspan adjusting mechanism, comprise mainframe (1), road wheel (5), it is characterized in that: symmetrical hinged two connecting rods (2) that are provided with respectively downwards on the horizontal gird of this mainframe (1), the hinged hydraulic ram (3) that arranges therein tilts between the upper link point of a connecting rod (2) and another connecting rod (2), this parallel hinged setting in two connecting rods (2) lower end wheel carrier (4) of independently walking, make this two connecting rods (2), with a hydraulic ram (3), walking wheel carrier (4) forms respectively two the parallel four-bar swinging gear in left and right, this walking wheel carrier (4) is rotatably mounted road wheel (5).
