Abstract

The utility model discloses a skidder capable of removing snow, which is used for removing snow twisting, drawing, etc. The utility model is characterized in that the foreside of a tractor is provided with a snow removing apparatus which is composed of a hydraulic ram, a snow pushing plate, etc., a buffering mechanism adopts a buffer rod structure which can be regulated conveniently, positive and reverse rotating control of a winch is improved simultaneously, and a second type angle gear group and a clutch collar structure are additionally arranged. The utility model has the advantages of simple structure, operational safety, flexible operation, and convenient repair and maintenance, and is suitable for being used for winter logging in a cold area forest.

Description

The log tractor that can remove the snow

The utility model relates to a kind of power actuated vehicle, particularly a kind of log tractor that removes the snow.

At present, China forest zone extensively adopts log tractor to carry out skidding operation, but the log tractor that use when felling winter in the forest zone that also is not suitable for cold zone.In the winter time, most of forest road in the north is covered by ice and snow, brings very big inconvenience to skidding operation, need manually open road, and so not only efficient is low, and workman's physical demands is big, and labour intensity is big; The capstan engine of existing in addition log tractor just, reversing control is complicated, and the buffer gear adjusting function is poor, and these all await improving.Relevant by retrieval document still finds no and the same or analogous record of the utility model.

The purpose of this utility model just provides a kind ofly can remove the log tractor that the road snow-up can remove the snow.

The technical solution of the utility model is: be fixed with hydraulic ram on the front bumper of trac., the piston rod of oil cylinder links to each other with pushing snowboard, and pushing snowboard links together by pushing snowboard connecting rod and front bumper; The structure of the buffer gear of trac. is a suit buffering pipe link on the axle of guide wheel, and buffering pipe link outer wall is nested together with thread connecting mode and shock strut, and recoil spring is enclosed within the outside of shock strut; In addition, in the power transmission circuit of line dish machine, set up the bevel gear set and the worm-and-wheel gear of П type structure, and in bevel gear set, be provided with slidably sliding hub between relative two finishing bevel gear cuters, with realize capstan engine just, reversing.

The utility model is simple in structure, uses reliably, and flexible operation, maintenance is convenient; Snow-removing device adopts movable hinge to connect, and is detachable, can regulate pushing snowboard and ground-surface spacing according to change of topography; Buffer gear can be adjusted the elasticity of caterpillar block easily, and can play the effect of crawler belt buffering when clearing the jumps under steam.When being particularly useful for northern forest zone logging operation in winter, uses the utility model.

Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.

Fig. 1 is a structural front view of the present utility model;

Fig. 2 is a structure birds-eye view of the present utility model;

Fig. 3 is a buffer gear structure cutaway view of the present utility model;

Fig. 4 is the utility model capstan engine power drive system scheme drawing.

With reference to accompanying drawing, the log tractor that can remove the snow, comprise driving engine 1, change speed gear box 2 and capstan engine 3, pass to change speed gear box 2 behind the takeoff output of driving engine 1, three route transferring power are arranged this moment, article one transfer route be each gear transmission in change speed gear box 2 to running device, finish normally advancing of trac.; Other two lines be after transmission output shaft 17 output through clutch for clutch control, pass to capstan engine and oil pump respectively.On the front bumper 4 of trac., with oil cylinder anchor ear 25 with hydraulic ram 5 fixed bits, the piston rod 8 of hydraulic ram 5 is hinged with pushing snowboard 6, the two ends of pushing snowboard 6 are equipped with pushing snowboard connecting rod 7, the other end of pushing snowboard connecting rod 7 is fixed on the front bumper 4, the straight motion of pushing snowboard energy when so just having guaranteed snow removing, and do not tilt.In order to guarantee the normal operation of hydraulic ram, also to dispose hydraulic reservoir, compression indicator and 3-position 4-way hand change over valve.After the power transmission of driving engine goes out fuel feed pump, make oil pump produce rotation, hydraulic oil sucks oil pump from fuel tank, produce pressure and enter the 3-position 4-way hand change over valve, when position that handle is in out, oil enters hydraulic ram, piston moves downward, and carries out snow removing work thereby drive pushing snowboard; When not working, the handle of change-over valve is removed to the position of " returning ", hydraulic oil change oil circuit enters from the bottom oil pipe of hydraulic ram, and piston stroking upward drives the pushing snowboard built on stilts, separates by clutch for clutch control then, and oil pump is quit work.

The utility model has also adopted the buffer gear of new-type structure, is used for adjusting the elasticity of caterpillar block, and plays the effect of crawler belt buffering when obstacle crossing.Its structure is: be fixed with the guide wheel connecting rod 11 that links to each other with guide wheel 9 on the vertical fine strain of millet 10 of suspension, be set with buffering pipe link 12 on the axle of guide wheel 9, the outer wall of buffering pipe link 12 is threaded, and connect together with shock strut 13, the outside of shock strut 13 is set with recoil spring 14, the spring lower surface contacts with the boss of shock strut 13 bottoms, the upper surface contacts with spring perch 15 on being sleeved on shock strut, spring bearing housing 16 also is enclosed within on the shock strut and with spring perch 15 and contacts, and the other end of spring bearing housing 16 is hinged on the suspension longeron 10.By the upper end of turn shock strut 13, i.e. the elasticity of scalable caterpillar block.

The utility model has added forward and backward control in the power transmission line of capstan engine, thus realized do not change car load just, fall under the fast situation, can change the effect of the forward and backward of capstan engine separately.Power is delivered to axle 18 through belt-driving after transmission output shaft 17 outputs, be provided with the bevel gear set 20 of the П type structure that forms by three finishing bevel gear cuter combinations at an end of axle 18, be meshing with each other between three gears, finishing bevel gear cuter 24 rotates synchronously with axle 18, finishing

bevel gear cuter

22 and 23 is around axle 26 idle running, be provided with slidably sliding hub 21 between the two, the slip of sliding hub 21 can also can be adopted alternate manner by fork controls.Axle 26 is coaxial with the worm shaft of worm-and-wheel gear 19, and worm gear is coaxial with capstan engine, and finally drives capstan engine 3 rotations.Because this П type unitized construction arranged, finishing bevel gear cuter 22 with 23 with opposite turning to around axle 26 idle running, stir shift fork, sliding hub can move forward or after move, engage finishing

bevel gear cuter

22 or 23 respectively, obtain rightabout rotation, thereby the forward and backward of realization capstan engine 3.
