Description
Technical field
The utility model relates to agricultural mechanical field; Refer in particular to the door-opening mechanism that a kind of valve that is used for device for transporting objects is opened automatically, the contactless seedling tube door-opening mechanism that seedling tube valve is opened automatically on a kind of specifically pot seedling conveying plant that is used for transplanter.
Background technology
Along with the raising of level of farming mechanization, transplantation technique is promoted in China's large tracts of land, and the automaticity of pot seedling transplanter is also increasingly high.At present; The seedling tube door-opening mechanism of pot seedling conveying plant mainly contains two kinds: a kind of valve guide rail or supporting plate of below the seedling tube, being equipped with, valve moves along guide rail or supporting plate, when valve through falling during the seedling mouth on guide rail or the supporting plate; Valve is opened; The shortcoming of this mode is between valve and guide rail or the supporting plate bigger friction to be arranged, and the driving torque of transmission device increases, and regular meeting is with mechanicalness noise; Another kind is that the lateral layout at valve has lug, bumps iron or slideway is opened valve through fixing, this mode shortcoming be noise big, can produce bigger mechanical shock, particularly evident when the working at high speed state, the parts inefficacy that is hit easily.
Summary of the invention
The purpose of the utility model is problems such as the mechanical shock that produces of the door-opening mechanism to existing transplanter pot seedling conveying plant is big, friction is big, noise is big, and a kind of contactless seedling tube door-opening mechanism of can be automatically, quickly and reliably valve being opened and closed is provided.
The purpose of the utility model solves through following technical scheme:
A kind of contactless seedling tube door-opening mechanism comprises transmission device, seedling tube and magnetic element, and wherein a side of transmission device is provided with the seedling tube that is fixedly linked with it, and the opposite side of said seedling tube is provided with the magnetic element that fixedly installs; Described seedling tube links to each other with the valve of its downside through torsionspring, and the top and bottom of torsionspring lay respectively on the homonymy side of seedling tube and valve, and the front of valve is provided with and the corresponding ferromagnetic component of magnetic element.
The lower ends place of the upper end of said valve and seedling tube is provided with the valve pin.
Described torsionspring upper end is fixedly linked with the seedling tube.
The upper end of said valve is provided with lug.
The utility model is compared prior art has following advantage:

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1-5: a kind of contactless seedling tube door-opening mechanism; Comprise transmission device 5, seedling tube 6 and magnetic element 1; Transmission device 5, seedling tube 6 and magnetic element 1 all are installed on the pot seedling conveying plant; Wherein a side of transmission device 5 is provided with the seedling tube 6 that is fixedly linked with it, is provided with the magnetic element 1 that is fixedly mounted on the pot seedling conveying plant at the opposite side of seedling tube 6, and magnetic element 1 adopts permanent magnet or electromagnet to process.Downside at seedling tube 6 is provided with coupled valve 4, and valve 4 is all processed with nonmagnetic substance with seedling tube 6.In order to make the valve 4 can auto-closing; Link to each other through torsionspring 2 between valve 4 and the seedling tube 6, the top and bottom of torsionspring 2 lay respectively on the homonymy side of seedling tube 6 and valve 4, under the situation that valve 4 is opened; The twisting resistance of torsionspring 2 will make valve 4 closures; Be provided with at the lower ends place of the upper end of valve 4 and seedling tube 6 and make seedling tube 6 and valve 4 relatively-stationary valve pins 7, the central shaft of valve pin 7 can be set at the center of rotation of torsionspring 2, wherein; The lower end of torsionspring 2 is positioned at the downside of valve pin 7, and the upper end of torsionspring 2 is positioned at the upside of valve pin 7 and is fixedly linked with the side of seedling tube 6; Can open automatically for making valve 4; On the front of valve 4, be provided with and magnetic element 1 corresponding ferromagnetic component 3; When seedling tube 6 moved to the position at magnetic element 1 place, the ferromagnetic component 3 on magnetic element 1 and the valve 4 attracted each other, when the gravitation that produces between magnetic element 1 and the ferromagnetic component 3 surpasses the twisting resistance of torsionspring 2; Valve 4 will be opened automatically, reach the purpose of opening valve 4 automatically.In order to limit the angle that valve 4 is opened, be provided with the lug 8 that can limit in the upper end of valve 4 simultaneously to the maximum opening angle of valve 4.
As shown in Figure 1; The contactless seedling tube door-opening mechanism of the utility model is installed on the pot seedling conveying plant; When the pot seedling conveying plant was worked, transmission device 5 drove 6 motions of seedling tube, when seedling tube 6 process magnetic elements 1; Ferromagnetic component 3 on the valve 4 attracts each other with fixing magnetic element 1; When the attraction between ferromagnetic component 3 and the magnetic element 1 during greater than the twisting resistance of torsionspring 2, valve 4 will be opened automatically, and the maximum opening angle of 8 pairs of valve 4 of lug of being provided with of valve 4 tops limits simultaneously; Seedling tube 6 continues to move forward, and when the attraction between ferromagnetic component 3 and the magnetic element 1 during less than the twisting resistance of torsionspring 2, valve 4 will be closed gradually.Wherein, valve 4 is in length and the magnetic strong and weak decision of the duration of opening by magnetic element 1, and the length of magnetic element 1 is long more, and magnetic is strong more, and the duration that opens the door of valve 4 is long more; Otherwise the time of then opening the door is short more.
The valve 4 of the utility model is not limited to being connected of valve pin 7 with the annexation of seedling tube 6, also can adopt movable buckle-type to connect.The contactless seedling tube door-opening mechanism of the utility model is simple in structure, moves fast and reliable and stable, and the noise of generation is less, has improved the job stability and the operating efficiency of transplanter.
The technology that the utility model does not relate to all can realize through prior art.
