Abstract

A crawler type profiling ground walking device comprises a rear driving wheel and a front guiding wheel. The front guiding wheel is a double-layer wheel, an axis of the front guiding wheel is mounted on a profiling support connected with a mounting frame for mounting the rear driving wheel by the aid of a support pull rod, a pull rod spring is sleeved on the support pull rod, a tension spring is mounted below the profiling support, and the rear driving wheel is a toothed wheel. A chain rail sleeved on the rear driving wheel and the front guiding wheel comprises a ground tooth, a connecting chain, a chain sleeve and a chain shaft, connecting pieces are arranged in the front and at the back of the ground tooth, and two sides of the ground tooth are manufactured into angles with a movement direction. The front guiding wheel of the crawler type profiling ground walking device uses the rear driving wheel as a center in cultivation, and the device is automatically adjusted according to unleveled height of ground to achieve the purpose of unchanged area of the chain rail contacting with ground, enlarges traction force and guarantees unchanged cultivation depth, thereby improving work efficiency and work quality and reducing oil consumption cost.

Description

Crawler type profiling ground walking device

Technical field

The utility model relates to field machine, and particularly a kind of energy adapts to any ground-surface crawler type profiling ground walking device.

Background technology

Traditional tiller walking is that single wheel drive walking or simple chain rail drive walking.Traditional chain rail walking connection mode is that led the way the in the past both sides of wheel of drive wheel have side plate, abbreviates dead connection as according to two-wheel width between centers captive joint.The connection mode of this walking is; Front-wheel, rear drive sprocket can not change in that ground level is in alignment with the farm implements of back.When farming, run into ditch, can not all land on ground before and after this bonded assembly, it the phenomenon the same with the single wheel drive walking (skidding in the walking position) forfeiture tractive force occurs when farming, thus work efficiency and workmanship when influencing tiller in work, oil consumption expense increasing etc.

The utility model content

For remedying above-mentioned deficiency, the utility model provides a kind of can adapt to any ground-surface crawler type profiling ground walking device.

The utility model crawler type profiling ground walking device, comprise rear driving wheel and front jocket wheel, front jocket wheel is double-deck wheel, its axle mounting is on the profiling support, the profiling support is connected with the erecting frame that rear driving wheel is installed by support rod, is with pull-rod spring on the support rod, tensioning spring is housed below the profiling support, rear driving wheel is a gear wheel, and the chain rail is enclosed within on rear driving wheel and the front jocket wheel.

Described chain rail is made up of lug tooth, connection chain, chain case and chain rivet, is provided with connecting strap, the angled making of lug tooth both sides and sense of motion before and after the lug tooth.

The utility model crawler type profiling ground walking device, front jocket wheel is the center with the rear driving wheel when farming, reaches the chain rail and the ground-surface area that lands is constant according to the ground-surface automatically regulating that is uneven, and has strengthened tractive force, has guaranteed that tilth is constant.So improved work efficiency and workmanship, the oil consumption expense reduces.

The specific embodiment

Below in conjunction with embodiment the utility model crawler type profiling ground walking device is done more detailed explanation.

Fig. 1 is the lateral plan of the utility model crawler type profiling ground walking device.

The utility model crawler type profiling ground walking device, comprise rear driving wheel 2 and front jocket wheel 3, front jocket wheel 3 is double-deck wheel, its axle 8 is installed in (see figure 2) on the profiling support 10, and profiling support 10 is connected with the left erecting frame 1a that rear driving wheel 2 is installed by support rod 9, is with pull-rod spring 11 on the support rod 9, tensioning spring 7 is housed below the profiling support 10, rear driving wheel 2 is a gear wheel, and rear axle 5 is installed on the right erecting frame 1, and chain rail 4 is enclosed within on rear driving wheel 2 and the front jocket wheel 3.

Chain rail 4 is made up of lug tooth 4a, connection chain 4c, chain case 4d and chain rivet 4e, is provided with connecting strap 4b, the angled making (see figure 3) of lug tooth 4a both sides and sense of motion before and after the lug tooth 4a.

Chain rail 4 is on rear driving wheel 2 time, and the chain hole of being made up of connection chain 4c and chain case 4d just in time is enclosed within on the tooth of gear wheel; In the time of on front jocket wheel 3, connecting strap 4b, connection chain 4c, chain case 4d and chain rivet 4e all sink between the two-layer cincture, have only lug tooth 4a holder (see figure 2) on cincture, and this structure can guarantee that front jocket wheel 3 guides direct of travel like clockwork.
