The specific embodiment
Core of the present utility model is for providing a kind of snowblower, and this snowblower adopts chain transmission system to carry out power transmission, by this structure design, has realized improving the purpose of snowblower transmission stability.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 to Fig. 3, wherein, Fig. 1 is the partial structurtes schematic diagram relevant with chain transmission system on the snowblower among a kind of embodiment of the utility model; Fig. 2 is the sectional view of Fig. 1; Fig. 3 is the structural representation of the first arrangement of clutch among a kind of embodiment of the utility model.
The utility model provides a kind of snowblower, clean processing for road pavement, warmhouse booth ceiling accumulated snow, comprise the driving shaft 1 that can be rotated motion, the walking driven unit 2 that is connected with driving shaft 1 and the task driven assembly 3 that is connected with driving shaft 1, walking driven unit 2 is provided be used to the transmission system of carrying out transmission with task driven assembly 3, driving shaft 1 is connected with the power set of snowblower, be used for the power of power set is exported, thereby drive the running of snowblower work package.
Specific works to snowblower decomposes as can be known, and snowblower is lower in working order generally speaking mainly has following two kinds of actions: 1, by fan component accumulated snow is carried out the blowing snow operation; 2, realize the walking of snowblower by running gear.For the power distribution that the snowblower power set can be provided is used for realizing walking to the driven unit 2(that walks) and task driven assembly 3(be used for realizing blowing snow), walking driven unit 2 and task driven assembly 3 are connected by transmission system, transmission system is given the transmission of power of driving shaft transmission on walking driven unit 2 and the task driven assembly 3, guarantees that it can run well.
In the prior art, the transmission adopted belt transmission because the belt that uses in the belt transmission is fragile, distortion, therefore easily causes the unstable of transmission.In order to address this problem, in the utility model, the transmission adopted sprocket drive system.
Sprocket drive system comprises chain and the sprocket wheel adaptive with it, chain strip adoption metal (ferrous materials) material is made, and the belt that provides in the prior art has higher intensity and resistance to deformation, anti-destructive (metal material has higher-strength than cortex, rubber or the plastic material that belt adopts).Therefore, the utility model adopts sprocket drive system to realize being connected between walking driven unit 2 and task driven assembly 3 and the driving shaft 1, can improve the stability of snowblower transmission.
Particularly, in a specific embodiment of the present utility model, driving shaft 1 is connected with walking driven unit 2 by the first arrangement of clutch 4.In the present embodiment the first arrangement of clutch 4 act as the disconnection and the parts that are connected that realizes driving shaft 1 and the driven unit 2 of walking, identical with the clutch configuration that uses in the prior art.Between driving shaft 1 and walking driven unit 2, the first arrangement of clutch 4 is set, can so that the walking driven unit 2 start gradually, this structure design had both avoided launch device the situation of overload to occur when starting, can improve again the mobility of snowblower, so that the mobile realization of snowblower is more convenient (when for example turning, so that the driving shaft 1 of turning side disconnects with road wheel, and opposite side connects simultaneously by solenoidoperated cluthes, and snowblower will turn to smoothly).
In the utility model, task driven assembly 3 is connected with driving shaft 1 by walking driven unit 2, and task driven assembly 3 is connected by the second arrangement of clutch between the driven unit 2 with walking.Said structure design drive 1, walking driven unit 2 and task driven assembly 3 are linked in sequence, when driving shaft 1 drives 2 running of walking driven unit, can also drive 3 runnings of task driven assembly by walking driven unit 2, so setting can improve the compact of device, simplifies the structure of snowblower.
In the above-described embodiments, task driven assembly 3 is connected by the second arrangement of clutch between the driven unit 2 with walking, the purpose that the second arrangement of clutch is set is to avoid the hard reboot of task driven assembly 3, can so that task driven assembly 3 turns round gradually, improve the stability of snowblower under the effect of the second arrangement of clutch.And if task driven assembly 3 directly is connected with walking driven unit 2, when 2 operation of walking driven unit, task driven assembly 3 causes energy waste also along with running under the snowblower off working state.
Particularly, the first arrangement of clutch 4 is centrifugal dry type friction clutch mechanism, and the first arrangement of clutch 4 comprises centrifugal hoof piece 4a and clutch disk, and centrifugal hoof piece 4a is arranged on the driving shaft 1, and clutch disk is arranged on the walking driven unit 2.
Particularly, the second arrangement of clutch is the ratchet engagement component, task driven assembly 3 and the 2 coaxial settings of walking driven unit, task driven assembly 3 can move along its axis, be provided with first on the task driven assembly 3 and cooperate ratchet 5, be provided with the second cooperation ratchet 6 that cooperates ratchet 5 suitable with first on the walking driven unit 2.
Based on above-described embodiment, the first face that cooperates ratchet 5 to cooperate ratchet 6 to be in contact with one another with second is suitable.
In order to control the second arrangement of clutch, the utility model also is provided with on task driven assembly 3 for promoting its axially movable shifting component 7, move by shifting component 7 driven unit 2 that can promote to walk, cooperate ratchet 5 and second to cooperate contact between the ratchet 6, separate thereby control first.
The snowblower that the utility model provides adopts the said structure design, and its operation process is: driving shaft 1 is connected on the main shaft of motor, when engine running, drives driving shaft 1 running; When engine speed reach certain value (〉=1600rpm) time, because the effect of centrifugal force is opened the centrifugal hoof piece 4a that installs on the driving shaft 1, the clutch disk of centrifugal hoof piece 4a on walking driven unit 2 is combined, drive 2 runnings of walking driven unit, the walking mechanism operation; When shifting component 7 under external force, the driven unit 3 that pushes the work forward is after driven unit 2 draws close to walking, the ratchet of task driven assembly 3 intercouples with the ratchet of walking driven unit 2, run-in synchronism drives operating mechanism's operation.
Above a kind of snowblower provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
