Specific implementation mode

Fig. 1 to Fig. 3 shows a hand held, electric seeder 10, including main body 12, and there are one by wall portion 14 and bottom for tool Portion 16 connects and the container 18 of formation, to accommodate material, such as seed.The vertical component at the rear portion and handle 20 of main body 12 20a connections, handle 20 also have the horizontal component 20b being connect with vertical component 20a.The horizontal component 20b of handle 20 is by main body 12 rear portion anteriorly extends, and is suspended from the upper opening end 18a of container 18.

The lower section of the horizontal component 20b of handle 20 is configured with manually pivotable switch 22, and the vertical component effect of handle 20 The side device of 20a is divided to have knob 24.

As illustrated in FIG. 4, the bottom 16 of container 18 have discharging window 26, under impeller 28 is installed.Main body 12 is built-in It is equipped with motor (not shown), the circuit (not shown) that is connect with motor and battery or battery pack (not shown) that electric energy is provided.When When closing of circuit, motor is activated, and output makes impeller 28 and agitation part 30 surround its respective central shaft through gear combination Rotation.When at least partly discharging window 26 exposes, the material in container 18 can fall on impeller 28, and stir the rotation of part 30 Turn the material that helps in container 18 to fall on impeller 28, and the material for falling on it is then passed through main body 12 by the rotation of impeller 28 Outlet 32 throw away.

In order to simplify operation, according to the arrangement of the utility model, the switch 22 of operation electric seeder 10 can be closed electricity Road, so that electric motor starting can also make discharging while to make impeller 28 and agitation part 30 surround its respective center axis rotation Window 26 switchs to exposing state from closed state.

As illustrated in FIG. 4, switch 22 has protrusion 22a, can be operated by the hand of user, to surround 34 pivot of pivotal axis Turn.Switch 22 has tail portion 22b, is connect with the upper end 36a for substantially " bending " shape middleware 36, so that when switch 22 pivots When movement, " bow " shape middleware 36 is around rotary shaft 36b rotations.One end of the lower end 36c and push piece 38 of " bow " shape middleware 36 It is fixedly connected, the other end of push piece 38 is fixedly connected with the blowing connecting rod 40 of long sheet and moves synchronously, and blowing connecting rod 40 can be with Substantially slided along 16 surface of the bottom of container 18.According to this arrangement, switch 22 is controlled through " bow " shape middleware 36 and push piece 38 Sliding motion of the blowing connecting rod 40 processed along the bottom of container 18 16；" bow " shape middleware 36 and push piece 38 constitute switch 22 and blowing Linkage mechanism between connecting rod 40.As illustrated in FIG. 5, blowing connecting rod 40 has enclosure portion 40a and window portion 40b.

The rear of the protrusion 22a of switch 22 is connect with spring 44, and spring 44 applies to switch 22 tends to illustrated in fig. 4 The biasing force of non-operating position.Push piece 38 is connect with torque spring 46, and spring 46 applies to push piece 38 tends to illustrated in fig. 4 The biasing force of upper position.

Electric seeder 10 illustrated in fig. 4 is in non-operating state.In this state, switch 22 is located at non-running Position, the circuit being connect with motor is in open state, so motor does not start, and therefore impeller 28 and agitation part 30 are also in Stationary state.In this state, push piece 38 is located at upper position, and blowing connecting rod 40 is located at detent position, wherein close to blowing The enclosure portion 40a of the free end of connecting rod 40 is located under the discharging window 26 of the bottom 16 of container 18, closing discharging window 26.

When user's Operation switch 22, be allowed to along Fig. 4 in a clockwise direction surround 34 shaft of pivotal axis when, spring 34 by Compression makes switch 22 reach operating position, is closed the circuit being connect with motor, starts motor, to drive impeller 28 and agitation part 30 surround its respective center axis rotation.Meanwhile movement of the switch 22 from non-operating position to operating position drives in " bow " shape Between part 36 make counter-clockwise direction rotation around rotary shaft 36b, the lower end 36c for making " to bend " shape middleware 36 pushes push piece 38 by Fig. 4 Shown in upper position slide into lower position generally downward, to drive blowing connecting rod 40 along the bottom of container 18 16, with one A direction for leaving handle vertical component 20a slides into release position, the wherein at least window portion of part blowing connecting rod 40 40b Under the discharging window 26 of the bottom of container 18 16, to expose at least part of discharging window 26.When 40, blowing connecting rod When release position, under the discharging window 26 of the bottoms 16 for being located at container 18 the window portion 40b of part blowing connecting rod 40, Be stored in the material (such as seed) of container 18 by the window portion 40b of discharge window 26 and blowing connecting rod 40 fall into impeller 28 it On, and the rotation of impeller 28 is then thrown away the material for falling on it by the outlet 32 of main body 12.

It is manually operable with control handle 24, the cam 48 in rotating handle 20 can so as to adjust " bow " shape middleware 36 To make the degree of counter-clockwise direction rotation, with adjustment push piece 38 upper position and the distance between lower position, to adjust The distance between the detent position of whole blowing connecting rod 40 and release position, so as to adjust the window portion 40b and appearance of blowing connecting rod 40 The size for the area that the discharging window 26 of the bottom 16 of device 18 overlaps each other, so as to adjust the material for being stored in container 18 fall into Speed on impeller 28.

When user no longer applies pressure to switch 22, spring 44 is biased power to switch 22, and switch 22 is made to surround pivot Shaft 34 pivots back to non-operating position with counter-clockwise direction, opens the circuit being connect with motor, stops the running of motor, impeller 28 And agitation part 30 also stops operating.Spring 46 is biased power to push piece 38, and push piece 38 is made to return to upper bit by lower position It sets, on the one hand " bow " shape middleware 36 is driven to be rotated clockwise around rotary shaft 36b, make " to bend " return of shape middleware 36 Position shown in Fig. 4, another aspect push piece 38 drive blowing connecting rod 40 to be slid into close to the direction of handle vertical component 20a Detent position is returned, the enclosure portion 40a close to the free end of blowing connecting rod 40 is made to return to going out positioned at the bottom 16 of container 18 Expect the detent position under window 26, closing discharging window 26.

Certainly, the foregoing is merely specific embodiment of the utility model, and not with limitation the utility model Range.The equivalent change or modification that all structure, feature and principles according to described in the utility model patent application range are done, It should be included in the scope of the utility model.In addition, it is to be understood that the above is only that the utility model can execute shows Example, and without departing substantially from the thought of the utility model, can carry out various modifications and/or replace.It should also be understood that Be, for sake of simplicity, now the various features of the utility model described in the content of single embodiment can also individually or It is provided with any appropriate sub-portfolio.
