In case device is fixed to tractor plowing apparatus, the primary importance that articulated jib is suitable for being called from least one transporting position moves to the second place that at least one is called the operating position, in transporting position, describedly takes turns supporting on the ground, in the operating position, the described wheel contacts with ground.
In addition, device have articulated jib is locked in transporting position and the operating position in locking member.
Therefore, in transporting position, control tractor plowing apparatus for example the operator of motocultivator can be easily equipment be transplanted on the zone for the treatment of farming from storing storehouse.In the operating position, motocultivator can be launched, and the instrument that generally is equipped on this tractor plowing apparatus can actuated that farming is carried out in described zone, and the existence of wheel can not hinder described instrument.
Patent documentation US6494270 describes the tractor plowing apparatus that a kind of outfit has the device of extendible travelling wheel.This device has hydraulic actuator, and it is suitable for start by the articulated jib of fixed support carrying.This hydraulic actuator also play articulated jib is locked in transporting position and the operating position in the effect of locking member.
This device not too is suitable for generally not having the common tractor plowing apparatus of hydraulic control device.Therefore, this device is used to professional tiller tractor plowing apparatus used.
In addition, the manufacturing of this device and the installation cost on tractor plowing apparatus are high.
In addition, this device with extendible travelling wheel is not easy to operator's manipulation.It need to add hydraulic control device.
Also has entirely mechanical device with extendible travelling wheel on market.This device has articulated jib, articulated jib with end that pivotal axis coordinates near have protruding pin, these protruding pins are applicable to be received in the groove of being located in fixed support.First pair of groove limits transporting position, and second pair of groove limits the operating position.Therefore, in order to be transitioned into the operating position from transporting position, the operator grips articulated jib, applies active force towards the direction of pivotable so that protruding pin breaks away from first pair of groove, then mobile articulated jib until protruding pin be locked in second pair of groove.
This solution has various defectives.Particularly, this device does not allow the quickly retracting wheel.The operator must be on articulated jib the application of force so that protruding pin breaks away from first pair of groove, then pivotal arm until protruding pin be locked in second pair of groove.First pair of groove that protruding pin break away to limit transporting position be difficulty normally, because the wheel supporting is on the ground, thereby a part of weight of bearing tractor plowing apparatus.In addition, protruding pin has the shape and size that are shaped and are matched with groove, so that protruding pin can not spontaneously break away from.Can guarantee so not break away from the equipment moving process, otherwise the cutting tool of meeting damage equipment.
On the contrary, second pair of groove of articulated jib disengaging restriction operating position is possible.Particularly, tractor plowing apparatus is used for the soil of many stones or ploughing or farming operation and bear a lot of vibrations of mud ground at least.Therefore, although locking member fluted and that protruding pin forms carries out on unmanageable soil in the process of farming, this device often breaks away from its operating position.In this case, articulated jib is pivoted to transporting position fiercely from its operating position, probably damages the axle of wheel shaft, even hurts sb.'s feelings.Therefore, this device is not very reliable in practicality.
Summary of the invention
The present invention is intended to make up known at least some defectives with tractor plowing apparatus of extendible travelling wheel.
Particularly, the present invention is intended to provide a kind of tractor plowing apparatus with extendible travelling wheel at least one embodiment, and this equipment allows travelling wheel from the transporting position to the operating position and the quickly retracting from the operating position to the transporting position on the contrary.
The present invention also is intended to provide a kind of tractor plowing apparatus with extendible travelling wheel at least one embodiment, this equipment does not have the risk that articulated jib breaks away from from the operating position to the transporting position.
The present invention also is intended to provide a kind of easy-to-use tractor plowing apparatus with extendible travelling wheel at least one embodiment of the present invention.
The present invention also is intended to provide a kind of economic tractor plowing apparatus with extendible travelling wheel of making at least one embodiment.
For this reason, the present invention proposes a kind of tractor plowing apparatus with extendible travelling wheel (4), this equipment has the fixed support (1) of articulated jib (2), articulated jib is used for carrying described travelling wheel (4), it is characterized in that, fixed support has at least one hole that is called the thin-and-long of bullport, bullport is suitable for admitting guide pin, guide pin and described articulated jib are connected and are suitable at described articulated jib moving in the bullport of described thin-and-long from the transporting position to the operating position and in the process that moves from the operating position to the transporting position on the contrary.
According to the present invention, by from the transporting position to the operating position and the on the contrary guiding of the pivotable from the operating position to the transporting position to articulated jib, convenient manipulation to articulated jib, and articulated jib is handled in the movement in the thin-and-long bullport of guide pin in being located at fixed support that is connected by at least one and articulated jib.This guiding makes the folding and unfolding of travelling wheel than quicker and easier in known tractor plowing apparatus.
In of the present invention one particularly advantageous embodiment, bullport is suitable for forming with guide pin articulated jib is locked at locking member in the operating position.
Therefore, the present invention has limited the danger of the intrinsic spontaneous upset of solution that the position keeps relying on fully the system with notch.
Particularly, bullport has the shape and size that are shaped and are matched with the guide pin shape and size, in order to can form, articulated jib is locked at locking member in the operating position.
This bullport for example has the shape that is limited by an edge, and the edge has a part, and therefore guide pin can also stop the pivotable of articulated jib from the operating position to the transporting position against this part.
There are a lot of possibilities in the shape and size of bullport and guide pin, in order to implement these locking members.
For example, pin can against this part be not vertical part, therefore this part stops the pivotable of articulated jib under the weight effect of wheel, thereby articulated jib is locked in the operating position.The material of making guide pin and bullport periphery edge also can participate in locking by very large coefficient of friction is set between the edge in pin and hole.
