According to the present invention, can obtain following effect:
In the present invention, takeing on device and rear output device together links and interlock.
Like this, because neat shoulder device and rear output device link and interlock, need not be provided for driving the transmission mechanism of neat shoulder device in addition, so, when above-below direction closely disposes neat shoulder device and rear output device mutually, needn't guarantee to be used for easily to set the clip position of suitable cauline leaf by the rear output device to this neat configuration space of takeing on the transmission mechanism of device transferring power.
Its result, can be by the bottom as much as possible of rear output device clamping cauline leaf, when even body tilts to the left and right, can prevent that also the posture of main root from big variation taking place, can prevent to make the cut-out mouth of cauline leaf become tiltedly (belonging to the defective commodity) as commodity by follow-up cauline leaf shearing device.
In the present invention, neat shoulder device has a pair of annular belt body of neat shoulder that the neat shoulder that is used to form direction extension is forwards, backwards used the left and right sides subtend configuration of carrying the road, the rear output device has a pair of bottom clamping of the left and right sides subtend configuration on the clamping output road, bottom that is used to form direction extension forwards, backwards and exports annular belt body, the top portion that annular belt body is exported in configuration bottom clamping under the state that overlaps up and down on position directly over the terminal part of takeing on annular belt body together, simultaneously, export the drive pulley that the annular belt body driving of neat shoulder usefulness is protruded and formed in the below of the driven pulley in the top portion of annular belt body to being configured in the bottom clamping, this drive pulley is configured on the terminal part of the annular belt body of neat shoulder.
Like this, the driven pulley in the top portion of annular belt body is exported in the bottom clamping and the drive pulley that is configured on the terminal part of the annular belt body of neat shoulder forms one because being configured in, so can simplify the drive structure of the annular belt body of neat shoulder, simultaneously, can reduce manufacturing cost.
And, can as far as possible closely dispose annular belt body of neat shoulder and bottom clamping and export annular belt body, thus, also can easily set the clip position of suitable cauline leaf by the rear output device.
In the present invention, the rear output device has: annular belt body is exported in a pair of bottom clamping that a pair of top clamping that is used to form the left and right sides subtend ground configuration on the clamping output road, top that direction forwards, backwards extends is exported annular belt body and is used to form the left and right sides subtend ground configuration on the clamping output road, bottom that direction forwards, backwards extends, the configuration of subtend ground met clamping output road, top and the bottom about annular belt body was exported in two top and the bottom clampings on above-below direction, simultaneously, export the below protrusion of the top drive pulley on the terminal part of annular belt body and form the bottom drive pulley that annular belt body driving usefulness is exported in the bottom clamping to being configured in the top clamping, this bottom drive pulley is configured in the bottom clamping exports on the terminal part of annular belt body.
Like this, owing to export the top drive pulley on the terminal part of annular belt body and be configured in the bottom drive pulley that the bottom clamping exports on the terminal part of annular belt body and form one being configured in clamping, so can simplify drive structure from annular belt body to two top and the bottom clampings that export, can reduce manufacturing cost simultaneously.
And, can be as close as possible with landing configuration top clamping export annular belt body and annular belt body is exported in the bottom clamping, can easily export the clip position that annular belt body is set suitable cauline leaf, can guarantee well by of the clamping and the conveying of clamping output endless belt, two top and the bottom to cauline leaf by two top and the bottom clampings.
In the present invention, annular belt body is exported in the top and the bottom clamping, disposes the position of the terminal part of each left and right sides mutually at fore-and-aft direction with staggering, and form open space between two terminal parts.
So, because in the fore-and-aft direction position of terminal part that the left and right sides of annular belt body is exported in clamping about the configuration with staggering mutually, and between two terminal parts, form open space, so can be released to the cauline leaf of exporting annular belt body clamping by the top and the bottom clamping and carry in the open space reliably, its result can prevent that cauline leaf from stopping up at two terminal parts.
In the present invention, in the top portion of the annular belt body of neat shoulder of pair of right and left, dispose driven pulley respectively, simultaneously, support each driven pulley by the driven pulley supporting device, on each driven pulley supporting device, elastic mechanism is set, each driven pulley is pushed to the direction elasticity of leaving the drive pulley on the terminal part that is configured in the annular belt body of each neat shoulder by each elastic mechanism.
Like this, because by the driven pulley supporting device of supporting driven pulley be arranged on the tension mechanism that elastic mechanism on this driven pulley supporting device constitutes the annular belt body of neat shoulder, so do not need to be provided with in addition tension mechanism, can simplify and tighten the structure of neat shoulder device, simultaneously, can cut down manufacturing cost.
And, when effect is big in the top portion at the annular belt body of neat shoulder of pair of right and left load, because each driven pulley overcomes the elastic pushing pressure of elastic mechanism and make the annular belt body of neat shoulder lax as backward movement, so can prevent to take on device together and root vegetables is taken place by the inconsiderate accident of breakage.
