Description

Small-size tracked vehicle that removes in woodland

Technical Field

The utility model relates to an agriculture and forestry mechanical equipment field, concretely relates to small-size tracked vehicle who removes in woodland.

Background

The forest land is an important component of forest resources, and the mechanized operation is an important link of the modernization of the forest production. The forest operation environment is very complicated, the ground is uneven and mostly soft soil, the ground covered with litter is easy to slip, weeds and shrubs are numerous, the movement is difficult, and the traditional small-sized plain operation vehicle cannot meet the operation requirements of the forest land. At present, most of mechanical equipment operating in woodland is inconvenient to move among woodlands due to large size, trees are easy to damage, and flexibility is lacked.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a barrier-crossing capability is strong, and is flexible, can adapt to the small-size tracked vehicle of complicated topography such as woodland.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

a small-sized crawler moving in woodland comprises a driving system, a frame, a thrust wheel and a crawler; the frame is the main part of small-size tracked vehicle, and actuating system and thrust wheel are all installed in the frame, and whole tracked vehicle is bilateral symmetry structure.

The driving system consists of a motor, a speed reducer, a driving wheel, a bearing mounting seat, a driving shaft, a flange plate, a shaft end check ring, a flat key and the like; the motor and the speed reducer are installed on the frame through bolts and nuts, power is transmitted between an output shaft of the speed reducer and the driving shaft through flat keys, and the driving torque is transmitted to the driving wheel by the driving shaft.

The frame consists of a main body frame, a nut, a screw rod and an adjusting frame, and the whole frame is of a bilateral symmetry structure; the main body frame is mainly formed by welding 50 multiplied by 30 multiplied by 3 rectangular hollow section steel; the adjusting frame connected with the front end of the main frame can stretch out and draw back to adjust the length of the whole frame.

The thrust wheel mainly comprises a supporting wheel, a dust cover, a connecting shaft, a shaft sleeve, a bearing, an elastic retainer ring and a flange nut; the thrust wheels mainly bear the weight of the whole crawler and roll in the crawler grooves to enable the crawler to move; the thrust wheels adopt a bilateral symmetry structure and are connected with the frame through connecting shafts, and 12 groups of support wheels are arranged on the frame.

The track adopts the rubber material, and the surface has the horizontal stripe to strengthen the frictional force with ground, and the recess meshes the drive track with the driving wheel upper teeth mutually in the middle of the internal surface and rotates, and internal surface both sides recess and supporting wheel cooperation prevent to drop when the track rotates.

The whole length of the crawler can be adjusted by the screw and the adjusting rack to match the length of the rubber track, so that the rubber track is in a tensioning state when being installed on the rack, and the crawler can normally work.

Detailed Description

The present invention is described in detail below with reference to the attached drawing figures:

as shown in the figure, the utility model discloses specifically include four major parts of actuating system, frame, thrust wheel, track, wholly be symmetrical structure, wherein the frame part is the main part, and other parts pass through bolt and nut to be fixed in the frame, mutually support.

The utility model discloses a concrete embodiment is that small-size tracked vehicle passes through the annular rubber track support of thrust wheel and coiling subaerial in forest zone, power produces through the motor, through the reduction gear, the drive shaft transmits the ring flange, the ring flange passes through the bolt fastening as an organic whole with the drive wheel, the drive wheel meshes continuously the track from the rear through the teeth of a cogwheel on the drive wheel and the recess in the middle of the track mutually under the effect of drive torque, the continuous ground resistance of overcoming of drive wheel is rolled up the track and is sent the place ahead, the thrust wheel has just rolled on the track continuously, thereby drive the motion of whole tracked vehicle. When the crawler-type crawler vehicle turns, only the motor on one side drives the driving wheel to rotate, so that the crawler on one side moves, the track is fixed in the groove on the inner side of the crawler by the thrust wheel, the crawler is prevented from transversely slipping, and the crawler vehicle turns smoothly. Rubber track uses the too much tensile deformation of number of times meeting, and the teeth of a cogwheel meshing with drive wheel, thrust wheel can produce not hard up, can stretch out the frame forward through the screw rod that becomes flexible in the frame, adjusts the rubber track of the tensile back of whole frame in order to cooperate, makes rubber track be in the tensioning state all the time, makes the creeper truck normally work, has improved the practicality of creeper truck.

The scope of the present invention is not limited to the specific embodiments, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
