Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a discharge tube of an unloader connected to a Glen tank is provided so as to be vertically swingable and horizontally rotatable by a driving means, a support tool for receiving the discharge tube in a retracted posture, and a discharge tube fixed in the retracted posture. The present invention relates to a combine unloader receiving structure provided with fixing means.

[0002]

[Prior art]

 Conventionally, as a means for mounting and fixing a discharge tube on a support, there is known one that uses a retaining band provided with a buckle-type fixture as shown in, for example, Japanese Utility Model Laid-Open No. 2-6849. Therefore, the discharge cylinder of the unloader can be securely fixed to the storage position when traveling on the road to and from the field or when the combine is mounted on the truck for transportation.

[0003]

[Problems to be solved by the device]

 However, if the discharge tube is accidentally lowered at a high speed when the discharge tube is stored, the support tool may be shocked and the discharge tube and the support tool may be deformed and damaged. In addition, during the harvesting work, it is often the case that the support pipe is received and supported by the support tool without being strapped to the support device. Contact noise sometimes caused contact noise.

An object of the present invention is to make it possible to easily prevent the deformation of the discharge tube and the generation of contact noise due to the collision with the supporting member by a rational configuration that effectively uses the fixing means.

[0005]

[Means for Solving the Problems]

 The characteristic configuration of the present invention is that the discharge cylinder of the unloader connected to the Glen tank is provided by the drive means so as to be vertically swingable and horizontally rotatable, and the support for receiving the discharge cylinder in the retracted posture and the discharge cylinder are stored. In a combine provided with a fixing means for fixing in a posture, a rubber band as a fixing means is installed over the left and right upper ends of the support tool and passing above the discharge tube in the retracted posture, and is lowered to the support tool side. The elasticity of the rubber band is specified in a state in which the rubber band erected over the left and right upper ends of the support tool elastically expands due to the load of the discharge cylinder due to the rocking, and a cushioning action for the discharge cylinder is obtained.

[0006]

[Action]

 In other words, by using the rubber band as the fixing means, the rubber band is erected so as to extend over the upper left and right ends of the support and pass above the discharge tube in the retracted posture, so that By making it possible to prevent lifting, and by specifying the elasticity of the rubber band, the rubber band erected over the left and right upper ends of the support elastically expands due to the load accompanying the downward swing of the discharge tube toward the support. As a result, a cushioning effect for the discharge cylinder is obtained.

[0007]

[Effect of device]

 As a result, it is possible to prevent deformation and damage of the discharge pipe and the support when the structure discharge pipe is lowered at high speed by a rational modification in which the fixing device also serves as the cushioning device, and to support the discharge pipe that is not fixed. Even if it floats finely on a tool, no contact noise is generated, which makes it highly practical.

【Example】

 As shown in FIG. 1, the pre-mowing treatment device 1, the threshing device 2 for treating grain culm from the pre-mowing device 1, the grain tank 3 for collecting the first product from the threshing device 2, and the grain from the gren tank 3 The unloader 4 for discharging particles, the boarding operation unit 5, and the like are mounted on a traveling vehicle body provided with a crawler type traveling device 6 to form a self-removing combine.

To configure the unloader 4, a horizontal feed screw conveyor 7 is provided at the inner bottom of the Glen tank 3, a vertical feed screw conveyor 8 is provided which is linked to the horizontal feed screw conveyor 7, and is connected from the vertical feed screw conveyor 8. A screw conveyor type discharge pipe 9 for discharging the grain is provided so that the discharge pipe 9 can be vertically swung by a hydraulic cylinder 10 and can be swiveled around a vertical axis P by an electric motor 11. Supports to load grains on the bed of a truck that stands by on a farm road, and to configure the discharge tube 9 to be able to switch between a storage position and a grain discharge position, and to receive the discharge tube 9 in the storage position. A tool 12 is provided.

As shown in FIGS. 2 to 4, in order to configure the fixing means for fixing the discharge tube 9 in the retracted posture, the rubber band 13 is welded to the left and right upper end sides of the support tool 12 across the headed pins 14 a and 14 b. In addition, it is constructed so as to pass over the discharge cylinder 9 in the retracted posture so as to prevent the discharge cylinder 9 from being lifted when the combine is transported. The rubber band 13 can be attached to and detached from one of the headed pins 14a by pulling the grip portion 13a of the rubber band 13. Further, as indicated by the phantom line in FIG. 3, the rubber band 13 laid across the left and right upper ends of the support tool 12 elastically expands and discharges due to the load of the discharge tube 9 caused by the downward swing to the support tool 12 side. The elasticity of the rubber band 13 is specified so that the cushioning effect on the cylinder 9 can be obtained, and the deformation of the discharge cylinder 9 due to the high-speed collision with the support tool 12 can be prevented by the rubber band 13 and is received by the support tool 12. Even if the discharge tube 9 floats finely due to the motion of the machine body, noise is not generated due to direct contact with the support tool 12.

In order to smoothly start the horizontal feed screw conveyor 7 and the vertical feed screw conveyor 8 by reducing the load of the stored grains on the horizontal feed screw conveyor 7, the horizontal feed screw conveyor 7 is provided inside the grain tank 3. As shown in FIG. 5, the pressure receiving plate 15 provided on the upper side of the pressure receiving plate 15 is reciprocally driven and swingable about the support shaft 16, and vertical walls 17 and 18 inclined to the left and right are alternately attached to the top of the pressure receiving plate 15. Further, the pressure receiving plate 15 and the vertical walls 17 and 18 are configured to be vibrated so that the grain naturally flows down to the horizontal feed screw conveyor 7.

As shown in FIG. 6, a lid 19 for cleaning is provided on the lower portion of the vertical feed screw conveyor 8 so as to be openable and closable, and the lid 19 is retracted from the inner surface of the case 8a at the front end portion a with respect to the screw rotation direction. At the rear end portion b, the thickness of the lid 19 is set so that the lid 19 slightly protrudes inside the case 8a. Therefore, a step that becomes a resistance is not formed.

As shown in FIG. 7, in forming the awning 20 of the boarding operation unit 5, an upward bulge 21 is provided on the front end side of the upper surface, and a ventilation port 22 is provided on the rear end vertical wall, and The awning 20 is prevented from being lifted up by the wind pressure acting on the bulging portion 21 and the venting of air from the vent 22 when the combine is transported.

[Other Embodiments] A drive configuration for vertically swinging and horizontally rotating the discharge cylinder 9 can be appropriately selected, and these are collectively referred to as drive means 10 and 11. The specific structure of the support 12 can be changed appropriately, and the mounting structure of the rubber band 13 for fixing the discharge tube 9 in the retracted posture can be selected appropriately. In short, the rubber band 13 can be spread over the left and right upper end sides of the support 12. Moreover, it is sufficient if the structure is such that it can be installed in a state of passing above the discharge cylinder 9 in the stored posture.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
