Abstract
The utility model relates to a damping seat for a tractor. Both sides of the bottom of a chair seat 1 are respectively provided with a set of connecting pieces 2. The connecting pieces 2 are hinged with one end of a crutch-shaped main force arm 4, and the other end of the crutch-shaped main force arm is hinged with a support frame 12 on a front foot connecting plate. The upper end of a spring guiding rod 15 which is sheathed with a spring 16 is hinged with the connecting pieces 2, and the lower end is penetrated through a lower spring base 14 on the crutch-shaped main force arm 4, and is limited by a nut 5. The upper end of a vibration damper is hinged with the crutch-shaped main force arm 4, and the lower end is hinged with back foot connecting plate 9. The crutch-shaped main force arm 4 is positioned in a slot of a limiting and clamping 10 on the front foot connection plate 11. The utility model has excellent vibration damping effect, and can prevent drivers form having diseases, such as gastroptosis, etc.
Description
The utility model relates to seat, especially a kind of shock absorbing seat that is used for the trac. on the four-wheeled tractor.
Trac., especially four-wheeled tractor are widely used in rural area and cities and towns, and it not only is used for farming operation, also are a kind of important transportation meanss.Thereby operator on the tractor often needs to be operated on the trac. over a long time.Because trac. vibration is big, and the seat on the trac. and trac. are and are rigidly connected, and without any vibration reducing measure, cause the chaufeur of many long-term driving four-wheeled tractors to suffer from gastroptosis and dizziness, headache, pain in the back, illness such as nauseating.
The purpose of this utility model is at trac., and especially the seat of the four-wheeled tractor problem of not having a vibration reducing measure provides a kind of trac. shock absorbing seat with good effectiveness in vibration suppression.
The utility model is achieved in that the trac. shock absorbing seat comprises a seat support, and seat bottom has left and right two groups of attaching partss, and attaching parts is hinged with an end that turns shape main force arm by bearing pin.The other end that turns shape main force arm is hinged by the support on bearing pin and the preceding footing connecting panel.The spring guide upper end is hinged with the attaching parts of seat bottom, and the lower spring cup that turns on the shape main force arm is passed in the lower end, and spacing with nut.Spring housing is contained on the spring guide, and the spring upper and lower end props up upper spring seat and lower spring cup respectively.With to turn shape main force arm hinged, the lower end is hinged with back footing connecting panel with lower bearing pin with upper pin in the upper end of shock absorber, and the preceding footing connecting panel in right side or left side is provided with spacing clamping plate, turns shape main force arm and is sandwiched in the slit of spacing clamping plate, prevents that seat from swinging.
Said shock absorber comprises upper bush, lower sleeve, and lower sleeve inserts in the upper bush and is bearing fit with upper bush.Inner sleeve at the bottom of having tin is connected in the upper bush one.A guide rod is connected in the lower sleeve.Guide rod passes the tube end of inner sleeve, and spacing with nut.Be with spring on guide rod and the inner sleeve.The shock absorber upper end is shaped on and turns the last pin-and-hole that shape main force arm links, and the lower end is shaped on the following pin-and-hole that links with back footing connecting panel.
The trac. shock absorbing seat is connected by the preceding footing connecting panel of and arranged on left and right sides and the connecting portion phase-splitting on back footing connecting panel and the trac. fuselage.
When chaufeur is seated on the seat support, when meeting less vibration, the spring generation elastic deformation of seat bottom both sides, spring guide slides up and down in lower spring cup, and seat support rotates around the bearing pin that turns shape main force arm upper end, vibration is reduced, when trac. jolts greatlyyer, vibrate when strong, the spring in the shock absorber produces distortion, turn the bearing pin of shape main force arm on preceding footing connecting panel support and swing up and down, the vibration of seat support is reduced greatly.
The utility model simple structure, reasonable in design, sturdy and durable, easy for installation, have fabulous effectiveness in vibration suppression, avoided because of trac. vibrates the various illness that cause to chaufeur, can alleviate driver fatigue simultaneously, increase work efficiency.
Fig. 1 is D structure figure of the present utility model;
Fig. 2 is a lateral plan of the present utility model;
Fig. 3 is that this reality has later-model front view;
Fig. 4 is the constructional drawing of shock absorber.
The utility model is described in further detail below in conjunction with embodiment shown in the drawings:
As shown in Figure 2, the trac. shock absorbing seat has a seat support 1, and one group of attaching parts 2 is each side arranged at seat support 1 bottom.An end that turns shape main force arm 4 is hinged by bearing pin 3 and attaching parts 2, and the other end that turns shape main force arm 4 is hinged with the support 12 on the preceding footing connecting panel 11 by bearing pin 13.The upper end of spring guide 15 is hinged by bearing pin 18 and attaching parts 2, and the lower spring cup 14 that turns on the shape main force arm 4 is passed in the lower end, and spacing with nut 5.Spring 16 is sleeved on the spring guide 15, and upper and lower side is against respectively on upper spring seat 17 and the lower spring cup 14.With to turn shape main force arm hinged, the lower end is hinged with back footing connecting panel 9 by lower bearing pin 8 by upper pin 6 in shock absorber 7 upper ends.For preventing the seat support wigwag motion, the preceding footing connecting panel 11 on right side is provided with spacing clamping plate 10.Turning shape main force arm 4 is contained in the slit of spacing clamping plate 10 (as shown in Figure 1).Shock absorber 7 is made of upper bush 20, lower sleeve 26.Lower sleeve 26 is positioned at upper bush 20, is bearing fit with upper bush 20.24 inner sleeve 22 is arranged in the upper bush 20 at the bottom of the band that is connected with it.A guide rod that is connected with it 25 is arranged in the lower sleeve 26.Guide rod 25 passes the tube end 24 of inner sleeve 22, and spacing with nut 23.The upper end of upper bush 20 have one with turn the last pin-and-hole 19 that shape main force arm links to each other, there is a following pin-and-hole 27 that links to each other with back footing connecting panel 9 lower sleeve 26 lower ends.
