Abstract
The utility model discloses a walking tractor, which belongs to farm machines, solves the problems in the prior art that the brake of the walking tractor is completely operated by hands, is difficult to operate and has bad brake effect. The walking tractor comprises a machine body, a gear-box and a braking system. The braking system comprises an air compressor, a gasholder, an air expansion pump, a brake lever and a tripping spring, wherein, the air compressor, the gasholder and the air expansion pump are respectively arranged and fixed on the machine body; a power shaft of the air compressor is connected with a driving shaft of the gear-box in a power-driven manner; the air compressor is connected with the gasholder through an air inlet pipe; the gasholder is connected with the air expansion pump through an air outlet pipe; a switch is arranged on the air outlet pipe; one end of the tripping spring is fixed on the brake lever, and the other end is fixed on the machine body; and a telescopic link of the air expansion pump is articulated with the brake lever. The walking tractor can be used for the farmland work, and also used for transportation.
Description
Technical field
The utility model belongs to a kind of field machine, specifically, relates to a kind of walker tractor.
Background technology
Continuous progress along with the mechanization of agriculture degree, walker tractor is because its volume is little, alerting ability is strong, can be engaged in several work, more and more be subjected to liking of friend peasant in the rural area, and increasing walker tractor is engaged in the communications and transportation operation in farm slack season.The brake safe performance of walker tractor also more and more comes into one's own.The drag of walker tractor is to adopt lever principle to realize by the M/C of chaufeur fully, its operating difficulties, braking effect are poor, usually cause traffic accident, at present, also do not have a kind of brake system failure-free walker tractor more because of unexpected brake failure.
Summary of the invention
The purpose of this utility model is for a kind of walker tractor is provided, to solve the technological deficiency that its drag of walker tractor of the prior art adopts M/C, operating difficulties, braking effect difference fully.
The utility model is realized by the following technical solutions: a kind of walker tractor comprises body, change speed gear box and brake system; Described brake system is the auto brake system of dying, and it comprises air compressor, gaholder, air expansion pump, brake lever and retarding spring, and air compressor, gaholder, air expansion pump are fixed on the body respectively; The dynamical axis of air compressor is connected by power transmission mode with the imput shaft of change speed gear box, and air compressor is connected by air inlet pipe with gaholder, connects by freeing pipe between gaholder and the air expansion pump, and freeing pipe is provided with switch; One end of retarding spring is fixed on the brake lever, and the other end is fixed on the body; The expansion link of air expansion pump is articulated in brake lever.
Described retarding spring is an extension spring.
Compared with prior art, the beneficial effects of the utility model are: owing to taked the auto brake system of dying, so, do not work or do not give under the situation of air expansion pump air feed at driving engine, the brake equipment of walker tractor is in normal braking mode, and its braking realizes by mechanical mode fully; Take glancing impact under walking states, chaufeur only need be operated the braking that the switch of brake system just can be realized walker tractor, and is simple to operate laborsaving, good braking effect; Because brake system has just realized braking under the effect of retarding spring, reduced the generation of fault, thereby improved the enforcement safety performance of walker tractor greatly.
Description of drawings
Accompanying drawing is the structural representation of the auto brake system of dying of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of walker tractor comprises body, change speed gear box 8 and brake system; Brake system comprises air compressor 1, gaholder 3, air expansion pump 6, brake lever 7 and retarding spring 10, and air compressor 1, gaholder 3, air expansion pump 6 are fixed on the body respectively; The imput shaft 9 of the dynamical axis of air compressor 1 and change speed gear box 8 connects by power transmission mode, and air compressor 1 is connected by air inlet pipe 2 with gaholder 3, connects by freeing pipe 4 between gaholder 3 and the air expansion pump 6, and freeing pipe 4 is provided with switch 5; One end of retarding spring 10 is fixed on the brake lever 7, and the other end is fixed on the body; The expansion link of air expansion pump 6 is articulated in brake lever 7.
Different with conventional walker tractor is, when driving engine of the present utility model is not worked, gaholder 3 does not have under the situation of pressure gas, and its brake equipment is in braking mode.Have only behind start the engine, driving engine drives the imput shaft 9 of change speed gear box 8 and rotates, gaholder has certain high pressure gas for 3 li, and open switch 5 on the freeing pipe 4, air expansion pump 6 action and when having offset the pulling force of retarding spring, brake lever of the present utility model just can be not in the position of braking.Described switch 5 has air feed and stops the function of air feed, and when stopping air feed, the gas that the air expansion pump is 6 li is bled off simultaneously, and brake lever 7 resets to braking position under the tension of retarding spring.
Claims (2)
1, a kind of walker tractor, comprise body, change speed gear box and brake system, it is characterized in that: described brake system is the auto brake system of dying, it comprises air compressor, gaholder, air expansion pump, brake lever and retarding spring, and air compressor, gaholder, air expansion pump are fixed on the body respectively; The dynamical axis of air compressor is connected by power transmission mode with the imput shaft of change speed gear box, and air compressor is connected by air inlet pipe with gaholder, connects by freeing pipe between gaholder and the air expansion pump, and freeing pipe is provided with switch; One end of retarding spring is fixed on the brake lever, and the other end is fixed on the body; The expansion link of air expansion pump is articulated in brake lever.
2, a kind of walker tractor according to claim 1 is characterized in that: described retarding spring is an extension spring.
