Existing snow removing machine mostly is heavy mechanical equipment, for narrow street or space, is difficult to put to good use open.And, when some present small-sized snow-removing device side are to thicker accumulated snow or harder accumulated snow, scoop up and require great effort very much, be difficult to remove totally.
Some electronic snow removing machines in addition, the operating type of snow is raised in many employings, with gear accumulated snow smashed and roll, and then blow to both sides by powerful hair-dryer, snow throwing lift is generally at about 10 ~ 15m, accumulated snow can be caused in reset procedure to flash, must the accumulated snow flashed be cleared up, increase workload.This equipment is inapplicable for the street of some community or densely populated place.
For the defect of prior art, the invention provides a kind of snow removing machine, below in conjunction with the drawings and specific embodiments, it is described further.
The axonometric drawing of the snow removing machine that Fig. 1 provides for the embodiment of the present invention; The lateral view of the snow removing shovel part that Fig. 2 is the snow removing machine shown in Fig. 1; The axonometric drawing of the snow removing shovel part that Fig. 3 is the snow removing machine shown in Fig. 1.
This snow removing machine, comprising: car body 1, wheel 5, push rod 2, snow removing shovel 3 and breaking snow take turns more than 4 major parts.
Car body 1 is airtight trapezoidal cabinet, and its front end face tilts, and forms certain angle, to facilitate shovel snow.Rear end face is fixedly connected with push rod 2, to facilitate propelling movement snow removing machine; The bottom of car body 1 is provided with at least 3 wheels 5 for walking.
Preferably, wheel 5 is set to 4, is symmetrically arranged in the both sides of car body 1.
Snow removing shovel 3 is leg-of-mutton hollow cylinder structure for cross section is similar to, and has leading flank, bottom side and trailing flank three faces.The trailing flank of snow removing shovel 3 is close to the front end face being fixed on car body 1, and leading flank, in the arcwall face caved in backward, makes the front end face of the leading flank of snow removing shovel 3 and car body 1 seamlessly transit; Angle between the leading flank of snow removing shovel 3 and downside is no more than 30 °, forms scoop structure.
Preferably, the bottom side of snow removing shovel 3 is downward-sloping, thus makes the shovel portion of snow removing shovel 3 front end downward-sloping, can better be scooped up by accumulated snow.
The inner back side face of snow removing shovel 3 arranges two jacks, arranges two slots in the front end face relevant position of car body 1, the two ends of heater 6 are inserted into the slot of car body 1 through the jack of snow removing shovel 3.
Heater 6 adopts dismountable connected mode, and needs to carry out waterproof sealing process to its junction and space, place, to prevent accumulated snow or snow-broth from infiltrating, affects the normal work of circuit.
Be provided with power supply in car body 1, and be arranged on the controller 9 on push rod 2; Described controller 9 is connected with power supply, and power supply is connected with two slots on car body 1 front end face.Heater 6 adopts heating rod or resistance wire, when being inserted into when its two ends in two slots on car body 1 front end face, can realize and being communicated with of power supply, thus can by the open and close of controller 9 control heater 6, even can also realize the power adjusting of heater 6, make it heat snow removing shovel 3, conveniently shovel snow.When accumulated snow is more open, heater 6 can be pulled down, or not heater 6, only rely on the scoop structure of its front end to be scooped up by accumulated snow.
Multiple breaking snow wheel 4 is fixed on wheel shaft 8 side by side, and the two ends of wheel shaft 8 are arranged on two sides of car body 1 by connecting rod 7.Wheel shaft 4 is just in time arranged on the front upper place of snow removing shovel 3, and making breaking snow take turns 4 can rotate at the leading flank recess of snow removing shovel 3.Breaking snow takes turns 4 by own rotation by the snow of bulk or ice fragmentation.
Connecting rod 7 is connected by rotating shaft with car body 1, and arranges drive at connecting rod 7 and the junction of car body 1, and is coupled together at the two ends of drive and wheel shaft 8 by chain or belt.
Above breaking snow wheel 4, the snow board 10 fixing with connecting rod 7 is set.The curved structure of snow board 10, both ends open, can prevent accumulated snow or foreign material from splashing upward, and accumulated snow can be guided to move to both sides, improves safety during breaking snow.
Wheel shaft 8 can adopt electronic and manpower two kinds of type of drive, to meet different environments for use:
Motorized motions mode is: in car body 1, arrange drive motors, and power is transported on drive by drive motors, drive drive to rotate, thus live axle 8 rotates; Drive motors is connected with the power supply in car body 1, and controls start and stop by the controller 9 on push rod 2.Gear can also be set on controller 9, rotate with different speed or even different directions to control wheel shaft 8;
Manpower type of drive is: the rotating shaft of drive and wheel 5 connected as one, make its synchronous axial system; Like this, when promotion car body 1 advances, can rotate by driven wheel axle 8 simultaneously.
In addition, be rotationally connected mode owing to adopting between connecting rod 7 and car body 1, therefore the height of connecting rod 7 can regulate.Car body 1 arranges upper limit structure and lower limiting mechanism, the activity space of control connection bar 7, make breaking snow wheel 4 remain at the leading flank recess of snow removing shovel 3; Also retaining mechanism is set simultaneously, makes connecting rod 7 can operationally remain on a certain height.
By regulating the height of wheel shaft, it is made to have more various processing mode to the accumulated snow of different-thickness, different terrain.
Spring vibration damper is set on wheel 5 or in the rotating shaft of wheel 5, makes the anti-seismic performance of car body better on the one hand, on the other hand can when ground relief, manual depression car body, makes snow removing shovel better contact with snow cover.
Breaking snow wheel 4 is the runner with 2 helical tooths, and the wheel shaft that described helical tooth and breaking snow are taken turns is 60 ° ~ 85 ° angles, and namely helical tooth is to side deflection.
Wheel shaft 8 arranges at least 4 breaking snows wheel 4, and the breaking snow of the left and right sides to take turns 4 installation directions contrary; When car body advances, snow can be pushed to the both sides of car body 1 by breaking snow wheel 4.
Controller 9 can also arrange display screen, can show the temperature of heater 6 or snow removing shovel 3, breaking snow wheel 4 turn to and rotating speed, power supply the information such as dump energy.
This snow removing machine is by the coordination work in combination of each functional part, with warmed-up snow removing shovel, snow cave shovel is risen, with breaking snow wheel, the snow of bulk is smashed again, and push it against both sides, thus can be more prone to long-pending thick snow carried out thawing dispose, and in reset procedure, do not adopt snow throwing to raise the working method of snow, only shift accumulated snow onto both sides, hew out a road, therefore accumulated snow can not splashes, is particularly useful for the occasions such as the intensive road of holdee (as community, school, factory) and uses.
This device structure is simple, volume is little, can complete the removing work of road snow mantle quickly and easily.And preheat and mode that both sides promote owing to have employed, and do not use hair-dryer, therefore in the whole course of work, noise is less, reaches the object of protection of the environment and energy conservation.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
