Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an auxiliary tank expanding mechanism for a combine grain tank.

[0002]

[Prior art]

 Conventionally, there has been an attempt to expand one side wall of a combine grain tank to the outside to increase the capacity of the tank, and the expansion and contraction of the outside wall operates the lock of the outside wall. It was done manually.

[0003]

[Problems to be solved by the device]

 However, since the Glen tank is generally located behind the operating part, during the harvesting work, in order to increase the capacity of the Glen tank, it is necessary to stop the work and get off the combine to operate the outer wall. In addition, the work efficiency is reduced and the driver is fatigued.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, the outer wall of the grain tank for storing threshed and sorted refined grains can be expanded to the outside to increase the capacity of the grain tank of the combine tank. Forming a contraction section where the left and right width gradually contracts downward, the lower end of the outer wall is pivotally supported above the contraction section through a pivot, and the outer wall is centered outside the pivot axis. The front and rear end edges of the outer wall extend inwardly to form an auxiliary tank, and an auxiliary tank is formed at the upper part of the auxiliary tank. A pinion meshing body having a shape is provided, and a pinion pivotally supported on the Glen tank main body is meshed with the pinion meshing body, and the auxiliary tank can be opened and closed by forward and reverse rotation of the pinion. Glen of Combines Is to St. provide an auxiliary tank expansion mechanism in link.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. In FIGS. 3 and 4, A indicates a combine, a cutting section 1 is provided in the front part, a driving section 2 is provided on the right side thereof, and a Glen tank is provided behind it. 3 is provided, a threshing unit 4 is provided above the left side thereof, and a swing selecting unit (not shown) is provided below the threshing unit 4, and the grain culm cut by the cutting unit 1 while traveling by the traveling unit 6 is threshed by the threshing unit 4. Then, the refined grain selected by the rocking and sorting unit is stored in the Glen tank 3 and carried out by the discharge auger 5 attached to the Glen tank 3.

As shown in FIG. 1, a lower portion of the Glen tank 3 is formed with a contracting portion 3a whose left and right widths are gradually contracted downward, and the lower end of the outer wall 7 is located above the contracting portion 3a. The outer side wall 7 is configured to be capable of expanding outwardly around the pivot axis 8, and the front and rear movable side walls 9 and 9 are inwardly extended from the front and rear end edges of the outer side wall 7. The auxiliary tank 15 is extended to form the auxiliary tank 15, and the auxiliary tank 15 can be opened and closed by the expansion mechanism B. That is, in the expansion mechanism B, as shown in FIGS. 1 and 2, the upper and lower edges of the front and rear movable side walls 9 and 9 are formed in an arc shape with the pivot 8 as a center, and the rack 10 as a pinion meshing body is attached to the upper edge. The rack 10 is meshed with a pinion 12 driven by a forward / reverse rotatable motor 11 arranged on the main body side of the Glen tank 3, and the motor 11 is installed in the operating section 2. By operating the open / close switch 13, the forward, reverse, and stop states can be set, and an electromagnetic clutch 14 is installed between the motor 11 and the pinion 12 to When 11 is stopped, the clutch 14 is in a free state.

Therefore, in order to increase the capacity of the Glen tank 3, when opening the auxiliary tank 15, it suffices to operate the opening / closing switch 13 provided in the operating unit 2 to rotate the motor 11 in the forward direction. Also, to return the auxiliary tank 15 to the normal position, all that is required is to operate the switch 13 and rotate the motor 11 in the reverse direction. Therefore, increase the capacity of the Glen 3 and restore it while continuing the harvesting work. You can

In particular, since the engagement of the pinion 12 and the rack 10 is used to transmit the rotation of the motor 11 to the auxiliary tank 15, it is possible to positively and reliably perform the opening / closing operation of the auxiliary tank 15. Since it is not necessary for the driver to get off and operate the auxiliary tank 15, the harvesting work can be continued without interruption, the work efficiency can be improved, and the work amount of the driver can be improved. The effect is to reduce fatigue and reduce fatigue.

Further, when the auxiliary tank 15 is expanded outward, the electromagnetic clutch 14 is in a free state. Even if the tank 15 comes into contact with the auxiliary tank 15, the auxiliary tank 15 does not move without resistance, and the auxiliary tank 15 is not damaged.

When the auxiliary tank 15 is expanded to the outside, its position is held by the weight of the grain in the grain tank 3, and the function as an auxiliary tank is sufficiently fulfilled. .

【effect】

 According to the present invention, the following effects can be obtained.

An arc-shaped pinion meshing body centering on the pivot is provided on the upper part of the auxiliary tank, and the pinion meshing with the pinion that is pivotally supported on the side of the Glen tank main body causes the pinion to rotate forward and backward. The auxiliary tank can be opened and closed smoothly and reliably by the small rotating force of.

Since the pinion is meshed with the pinion meshing body provided on the upper part of the auxiliary tank, it is possible to prevent the pinion from meshing the grains stored in the Glen tank and the auxiliary tank. The opening / closing operation of the auxiliary tank can be well ensured.

Since the lower end portion of the outer wall is pivotally supported above the reduced portion formed in the lower portion of the Glen tank via the pivot, an auxiliary tank formed by the outer wall and the front-rear movable side wall is provided. Even when the grain tank capacity is increased by expanding the grain outward, the grains stored in the auxiliary tank are also smoothly and reliably stored in the reduced part as the grains in the grain tank are carried out. If the grain carrying-out means such as a screw conveyor is provided in the reduction unit, the grains in the grain tank and the auxiliary tank can be reliably carried out.

By rotating the pinion forward and backward, the opening and closing of the auxiliary tank can be positively and reliably performed, so that the driver does not have to get off and open and close the auxiliary tank. Therefore, the harvesting work can be continued without interruption, the work efficiency can be improved, and the work load and fatigue of the driver can be reduced.
