Japanese Patent Laid-Open No. 2004-267029

In the said conventional structure, since the regulation member and the detection switch were respectively provided in the state supported by the threshing apparatus side, there existed the following disadvantages.

That is, since a threshing apparatus is equipped with the barrel rotated at high speed while having a large weight inside the threshing apparatus, when threshing a harvesting grain stem with a barrel, a threshing apparatus accompanies execution of work A strong vibration is generated. And since a regulating member and a detection switch were supported by the threshing apparatus side, it originates in the strong vibration which generate|occur|produces with threshing operation being performed, and there existed a possibility that a regulating member and a detection switch might raise a problem.

Therefore, aiming at the improvement of durability was calculated|required, making it possible to perform an operation|work favorably by operating a threshing apparatus in the operating state suitable for canine cutting and threshing operation at the time of a dog cutting threshing operation.

The characteristic structure of the combine which concerns on this invention is,

The threshing apparatus which carries out a threshing process, conveying a harvesting grain stem with a threshing feed chain,

The grain stem conveying apparatus which conveys the harvesting grain stem mowed by the harvesting|reaping part toward the said threshing feed chain,

A grain stem supply unit for manually supplying a grain stem to the threshing device by an operator during the dog seed cutting threshing operation;

A regulating member provided in the canister cutting threshing grain stem supply unit and switchable between a deregulation state enabling the supply of a grain stem by manual operation and a regulated state regulating the supply of a grain stem by manual operation;

a detection sensor for detecting whether the regulating member is in the regulated state or the regulated state;

A threshing control unit for controlling the drive speed of the threshing device is provided so that when the detection sensor detects the regulation state, it becomes a mowing operation state, and when the detection sensor detects the regulation release state, it enters the operation state for dog cutting and threshing. become,

The support member which supports the said detection sensor is connected and fixed to the frame which supports the said grain stem conveyance apparatus,

The regulating member is supported by the supporting member so as to be oscillating around a lateral axis, and is configured to be switched between the regulated state and the regulated state by oscillation around the axial center.

According to this invention, when a regulating member is switched to a regulation release state by manual operation, and a detection sensor detects it, a threshing control part will control the drive speed of a threshing apparatus so that it may become the operation state for threshing threshing. That is, when an operator performs a cutting threshing operation, a threshing feed chain is driven in the operating state suitable for cutting and threshing, for example, driven at low speed rather than the drive speed in the operating state for mowing operations.

If the regulating member is in a regulated state, since a grain stem cannot be manually supplied to the forage cutting and threshing grain stem supply part, at the time of a dog cutting threshing operation, it is necessary for an operator to always switch a regulating member to a release state. As a result, since a threshing apparatus is driven in the driving|operation state for dog cuttings threshing at the time of a dog cutting threshing operation, an operation|work can be performed favorably.

The detection sensor is supported by the support member connected and fixed to the frame body which supports a grain stem conveyance apparatus, and the regulating member is supported by the support member so that it can rock|fluctuate around a lateral axis center. Thus, since a detection sensor and a regulating member are supported by the grain stem conveyance apparatus side, since strong vibration does not act compared with the case where it equips with the threshing apparatus side, fear of causing a problem decreases, and durability improvement can be aimed at.

In addition, the detection sensor and the regulating member are not directly supported by the frame, but are supported by a supporting member connected and fixed to the frame. In this way, by adding a supporting member and setting it as the structure which supports a detection sensor and a regulating member, in order to support a grain stem conveying apparatus, even if it does not perform special processing to the frame body used as a large-sized member, it regulates in the position suitable for regulation of grain stem supply. The member may be provided, and the detection sensor may be provided at a position suitable for detecting the state of the regulating member.

Therefore, at the time of cutting and threshing work, it is possible to improve durability while operating the threshing apparatus in an operating state suitable for cutting and threshing work, and it is possible to achieve a simple This can be addressed by structural improvement.

In the present invention, it is preferable if a pressing means for swinging and pressing the regulating member toward the regulated state is provided.

According to this configuration, since the regulating member is oscillating and pressed toward the regulated state by the pressing means, the regulating member can be accurately maintained in the regulated state by the pressing force of the pressing means when the dog cutting operation is not being performed.

In the present invention, it is preferable if the urging means is provided in such a state that when the regulating member swings toward the deregulation state beyond the predetermined oscillation position, it swings and presses the regulating member toward the deregulation state.

According to this configuration, when the regulating member swings from the regulation state to the regulation release state side and exceeds a predetermined swing position, the pressing means swings and presses the regulation member toward the regulation release state. That is, the regulating member can be held in position in each of the regulated state and the regulated released state by one pressing means.

In the present invention, the accommodating table which receives and guides the grain stem supplied manually by an operator at the time of the canister cutting threshing grain stem supply part at the time of a canis cutting threshing operation, and the harvesting grain stem conveyed from the said grain stem conveying apparatus is pressed and guided from above A guide rod is provided,

It is preferable if each of the said accommodating table and the said guide rod is supported by the said support member so that it can rock|fluctuate around the lateral axis center of the body front part side.

According to this structure, it can supply to a threshing apparatus in a stable attitude|position, accommodating and guiding the grain stem supplied by hand in a accommodating table at the time of a threshing work for threshing. At the time of the harvesting operation by a harvesting part, it can transmit toward a threshing apparatus favorably and can convey it, pushing and guiding the harvesting grain stem conveyed from a grain stem conveying apparatus from upper direction with a guide rod.

In addition, since each of the accommodating table and the guide rod is supported by the support member so as to be oscillating around the lateral axis of the body front side, for example, during maintenance work, each of the accommodating table and the guide rod is mounted on the body front side. It can be made to swing upward around the lateral axis, and the accommodating table and guide rod do not interfere with the operation, making it easy to perform the operation.

In the present invention, it is preferable if the regulating member is supported so as to be swingable around the same shaft center as the swing axis of the accommodating table.

According to this configuration, the regulating member and the accommodating table are supported so as to be swingable around the same axial center. Therefore, the support structure can be made simple by sharing a rocking|fluctuation shaft center.

In this invention, in the said regulation state, it is suitable if the said regulating member is accommodated and supported by the said accommodating table, and the lower limit position is prescribed|regulated.

According to this configuration, when the regulating member is switched to the regulating state, the regulating member is accommodated and supported by the accommodating table, further downward oscillation is prevented, and the lower limit position is defined.

Therefore, when a threshing operation is not performed, if a regulating member becomes a regulation state, it will contact from an upper side with respect to a accommodating table, and it can double use the pressing member which holds a accommodating table.

In this invention, if the said regulating member is provided outside the body lateral direction rather than the said accommodating table, it is suitable.

According to this configuration, since the regulating member is located on the outer side of the body in the lateral direction than the accommodating table, the regulating member is located at a position close to the operator who is on the outside in the lateral direction of the body when changing the posture manually during cutting and threshing. This makes it easy to work with.

In this invention, if the said support member is located in the upper vicinity location of the conveyance path|route of a harvesting grain culm mowed by the said harvesting part and conveyed backward, if it is provided in the form along a grain stem conveyance direction, it is suitable.

According to this structure, since a support member is located in the upper vicinity point of the conveyance path of a harvesting grain stem, and is provided in the form along a grain stem conveyance direction, By installing in a long shape along a grain stem conveyance direction, conveyance of a harvesting grain stem is inhibited It becomes possible to install a regulating member in the position suitable for the regulating action|action which regulates supply of a grain stem without work.

In this invention, it is suitable if the manual operation part for switching operation of the said regulating member is provided in the state integrally connected with the said regulating member.

According to this configuration, since the regulating member is provided with the manual operation unit integrally, the operator can perform the posture change operation of the regulating member by holding the manual operation unit by hand. Although the regulating member is provided at a position suitable for regulating the supply of grain stems, the manual operation unit can be provided at a position that is easy to operate different from the regulating member, thereby improving operability compared to holding and operating the regulating member by hand. it becomes possible to
