DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a grain feeder, in which a grain feeding tank is provided with a horizontal feed screw conveyor at the inner bottom thereof, and a pressure receiving plate for reducing the load of the stored grain on the horizontal feed screw conveyor is provided inside the grain tank. The present invention relates to a combine grain storage unit provided above a lateral feed screw conveyor so as to be capable of driving vibration.

[0002]

2. Description of the Related Art Conventionally, a dedicated drive system for vibrating a pressure receiving plate is configured separately from a drive system of a lateral feed screw conveyor so that grains in a Glen tank smoothly flow naturally to a horizontal feed screw conveyor. [For example, see Japanese Utility Model Laid-Open No. 4-133147, FIG. 5].

[0003]

However, if the drive system for the pressure receiving plate and the drive system for the lateral feed screw conveyor are separately formed, the drive structure becomes complicated, and there is room for improvement in terms of cost and production. SUMMARY OF THE INVENTION An object of the present invention is to improve the drive system of the pressure receiving plate and the drive system of the lateral feed screw conveyor so that the structure is simple, inexpensive, and easy to manufacture.

[0004]

A feature of the present invention according to claim 1 is that a horizontal feed screw conveyor is provided at the inner bottom of a grain storage grain tank, and a load of stored kernels to the horizontal feed screw conveyor is reduced. In a combine in which a pressure receiving plate to be reduced is provided so as to be capable of being driven and vibrated above the horizontal feed screw conveyor inside the Glen tank, a vibration drive means for driving the pressure receiving plate to vibrate is directly connected to the horizontal feed screw conveyor. An eccentric cam is formed on the boss portion of the driving pulley, and a vibration driving member that vibrates the pressure receiving plate by reciprocating in conjunction with the rotation of the eccentric cam is provided. The point is that the bearing forming the action portion is fitted around the eccentric cam.

[0005] A feature of the present invention according to claim 2 is that, in the feature of the present invention according to claim 1, the vibration driving member is supported by a support shaft of a pressure receiving plate.

A feature of the present invention according to claim 3 is that, in the feature of the present invention according to claim 1, the vibration drive member is supported by a bearing.

[0007]

According to the first aspect of the present invention, the vibration driving member of the vibration driving means for vibrating the pressure receiving plate is interlocked with the eccentric cam formed on the boss portion of the driving pulley directly connected to the transverse screw conveyor. Most of the components can be shared between the driving system of the pressure receiving plate and the driving system of the horizontal feed screw conveyor, and the driving system of the pressure receiving plate and the driving system of the horizontal feeding screw conveyor are inexpensive due to simplified structure. And easily manufactured. In addition, the operating portion for the vibration drive member on the eccentric cam side is constituted by a bearing externally fitted to the eccentric cam,
Since the vibration drive member is reciprocated with the rotation of the eccentric cam without sliding the eccentric cam and the vibration drive member, the vibration drive member is reciprocated by the eccentric cam, but the backlash is generated. The wear of the eccentric cam and the vibration driving member, which is a factor of the above, can be prevented.

According to the second aspect of the present invention, the vibration driving member is supported by the support shaft of the pressure receiving plate, and the vibration driving member is moved in a direction perpendicular to the direction in which the eccentric cam contacts and presses the vibration driving member. Since the position change with respect to the eccentric cam is allowed, even if there is some error in the center distance between the lateral feed screw conveyor and the support shaft of the pressure receiving plate, the position change of the vibration driving member with respect to the eccentric cam The vibration driving member can be assembled by absorbing the error.

According to the third aspect of the present invention, since the vibration driving member is supported by the bearing and the vibration driving member is positioned with respect to the eccentric cam, the vibration driving member is rotated with the rotation of the eccentric cam. Can be smoothly swung back and forth without being twisted.

[0010]

According to the first aspect of the present invention, while the grains in the Glen tank can smoothly flow naturally to the horizontal screw conveyor by the vibration of the pressure receiving plate, the driving system of the pressure receiving plate and the horizontal feed screw conveyor can be used. Drive system can be manufactured easily and inexpensively.
In addition, it is possible to provide a combine grain storage unit having excellent durability without rattling.

According to the present invention, the workability of assembling the vibration driving means can be improved.

According to the third aspect of the present invention, the operation of the vibration driving means can be performed smoothly.
