Description

A kind of Novel minitiller internal combustion engine dust guard

Technical field

The utility model is related to mini-tiller field more particularly to a kind of Novel minitiller internal combustion engine dust guards.

Background technology

Tiller is a kind of utility model machinery of farming operation, and mini-tiller has light-weight, volume with compact internal combustion engine It is small, it is simple in structure the features such as.Mini-tiller is widely used in Plain, mountain area, the nonirrigated farmland on hills, paddy field, orchard etc..Mix corresponding machine The several work such as tool can carry out.Mini-tiller can freely exercise in field, user-friendly and storage, eliminate large-scale agricultural Machinery cannot be introduced into the worry of mountain area field, be optimal selection of the machine for people.

Tiller when in use, due to dusty, bad environments.Air filter clean-up effect is poor, and dust easily sucking is started Machine causes the failures such as scuffing of cylinder bore.Maintenance cost is high, is unfavorable for promoting the use of, meanwhile, service time interval is short, reduces working efficiency, It is unfavorable for being smoothed out for farming.

Existing tiller internal combustion engine is unable to control the size of air inflow, leads to internal combustion due to not having regulating device of air door Machine difficulty in starting is also easy flame-out after startup.

Utility model content

In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide a kind of novel micro- The machine of ploughing internal combustion engine dust guard, can purify the regulating device of air door added into the air in internal combustion engine can also improve internal combustion The starting efficiency of machine, prevents it from misfiring condition occur.

Technical solution is used by the utility model solves above-mentioned technical problem：

A kind of Novel minitiller internal combustion engine dust guard, including internal combustion engine further include grade one filter, air filter pipe and air door Regulating device is connected between regulating device of air door and grade one filter by air filter pipe, and grade one filter is rotatably connected in air filter Guan Shang, regulating device of air door are fixedly connected with internal combustion engine.

Further, regulating device of air door includes pipe connecting seat, pedestal, throttle lever, joint for pipe, pipe connecting seat Be fixedly connected with air filter pipe, pipe connecting seat offers the bottom tub to match with pedestal, and pedestal is located in bottom tub, pedestal and Joint for pipe center offers venthole, and large through-hole and small through hole are offered on throttle lever, is fixedly installed on joint for pipe There is a fixed block, throttle lever is rotatablely connected by large through-hole and fixed block, and joint for pipe offers to be rotated for throttle lever Behaviour area, joint for pipe are fixedly connected with internal combustion engine.

Further, pedestal and joint for pipe offer screw through-hole, and pedestal and joint for pipe are screwed company It connects.

Further, the height of pedestal is more than the depth of bottom tub.

Further, rotatable setting angle of the grade one filter on air filter pipe is 360 degree.

Advantageous effect：

Grade one filter meeting filtration, purification falls the dust in extraneous air, prevents internal combustion engine from occurring because filtering is not thorough Barrier, extends the maintenance period of internal combustion engine, improves working efficiency；When the internal combustion engine starts up, made by rotary air valve handle Small through hole is located at immediately below venthole, and air inflow can tail off at this time, and mixing air exhaustion is dense, and internal combustion engine is easy for starting, warm after startup After degree rises, then rotary air valve handle makes large through-hole be located at immediately below venthole, and air inflow increases at this time, avoids in this way Gaseous mixture overrich causes to stop working in internal combustion engine.

Wherein, grade one filter 1, air filter pipe 2, pipe connecting seat 3, bottom tub 31, screw through-hole 32, pedestal 4, venthole 41, throttle lever 5, large through-hole 51, small through hole 52, joint for pipe 6, fixed block 61.

Specific implementation mode

By make the structure feature to the utility model and the effect of being reached have it is further understand and understanding, to compared with Good embodiment and attached drawing cooperation detailed description, are described as follows：

As shown in Figures 1 to 5, a kind of Novel minitiller internal combustion engine dust guard, including internal combustion engine, as the utility model Improvement, further include grade one filter 1, air filter pipe 2 and regulating device of air door, between regulating device of air door and grade one filter 1 It is connected by air filter pipe 2, grade one filter 1 is rotatably connected on air filter pipe 2, and regulating device of air door is fixedly connected with internal combustion engine.

In use, the air from outside that grade one filter 1 can be purified effectively, these air with internal combustion engine by being connected Air filter pipe 2 enter internal combustion engines, while air inflow can be adjusted in regulating device of air door, when startup, pass through tune Section makes air inflow reduce, and mixing air exhaustion is dense, and internal combustion engine is easy for starting, and increases air inlet by adjusting after temperature rise after startup Amount causes internal combustion engine flame-out to avoid gaseous mixture overrich.

Regulating device of air door includes pipe connecting seat 3, pedestal 4, throttle lever 5, joint for pipe 6, pipe connecting seat 3 with it is empty Chimney filter 2 is fixedly connected, and pipe connecting seat 3 offers the bottom tub 31 to match with pedestal 4, and pedestal 4 is located in bottom tub 31, bottom Seat 4 and 6 center of joint for pipe offer venthole 41, large through-hole 51 and small through hole 52 are offered on throttle lever 5, pipe connects Fixed block 61 is fixedly installed on first 6, throttle lever 5 is rotatablely connected by large through-hole 51 and fixed block 61, and joint for pipe 6 opens up There are the behaviour area rotated for throttle lever 5, joint for pipe 6 to be fixedly connected with internal combustion engine, when the internal combustion engine starts up, rotary air valve Handle 5 so that small through hole 52 is located at immediately below venthole 41, and air inflow can tail off at this time, and mixing air exhaustion is dense, and internal combustion engine is easy for Start, after startup after temperature rise, then rotary air valve handle 5 is so that large through-hole 51 is located at 41 underface of venthole, at this time air inlet Amount increases, and avoiding gaseous mixture overrich in internal combustion engine in this way causes to stop working.

Pedestal 4 and joint for pipe 6 offer screw through-hole 32, and pedestal 4 and joint for pipe 6 are fixed by screws.

The height of pedestal 4 is more than the depth of bottom tub 31, when throttle lever 5 rotates at this time, will not rub with pipe connecting seat 3 It wipes.
