Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grain transfer device in which a transfer spiral is provided in a cylindrical body, and the middle part of the transfer spiral can be interrupted.

[0002]

[Prior art]

 Conventionally, a transfer spiral was installed in a cylindrical body, and the transfer shaft and the cylinder of the transfer spiral were intermittently divided in the middle thereof, and the end of the transfer shaft on the upstream side in the grain transfer direction was held by the cylindrical body. It is supported via a support arm, a bearing holder, and a bearing, and the dividing part of the transfer shaft is interlockably connected so that the bearing is supported by the bearing holder and a spacer fitted on the inner circumference on the upstream side in the grain transfer direction. The held grain transfer device is already known.

[0003]

[Problems to be solved by the device]

 In the known grain transfer device, dust mixed in the transferred grains enters the bearing through the gap between the overlapping portion of the bearing holder and the spacer. Could not be transferred.

[0004]

[Means for Solving the Problems]

 According to the present invention, a transfer spiral is installed in a cylindrical body, and the transfer shaft and the cylinder of the transfer spiral are intermittently divided in the middle thereof, and the end of the transfer shaft on the upper side in the grain transfer direction is held in the cylindrical body. With the support arm and bearing holder supported through the bearing and the disconnection part of the transfer shaft interlockingly connected in a removable manner, the bearing is fitted to the bearing holder and the inner circumference on the upper side thereof. In addition, it is supported by a spacer whose end surface is substantially flush with each other, and is transferred by sliding and closing the soft material held by the support cup mounted on the transfer spiral over the end surface of the bearing holder and the spacer. The above problem was solved by preventing dust from entering the bearing even if it is mixed in the grain.

[0005]

[Action]

 When the spiral shaft in the cylinder is rotationally driven, the transfer spiral rotates in the cylinder and transfers the grain from one end side to the other end side. Then, the transfer device can be divided at an intermediate part, and when connecting and making a series, the end part of the cylindrical body is fitted and the end part of the spiral shaft is power-transmittingly connected by an anchor. When transferring the grain with the dividing part connected, the end of the spiral shaft on the upper side of the dividing part is held by the cylinder through the bearing, bearing holder, and support arm, and the spiral is held in that state. The shaft rotates. Further, during the transfer of the grains, the grains containing various kinds of waste are pressed against the bearing holder and the spacer by the transfer screw, which is received by the support cup and guided to the outside, so that the support cup and the bearing holder are separated from each other. Even if the debris enters from between, the soft material slides on the end surface of the fitting part between the inner circumference of the bearing holder and the outer circumference of the spacer to close the end of the fitting part. The debris does not penetrate into the bearing from the part, and the bear ring retains its function for a long time.

【Example】

 An example in which one embodiment of the present invention is applied to a grain discharging device of a combine will be described. A threshing device 3 is mounted on one side of a machine base 2 having a traveling device 1 and a driving section is surrounded on the other side. A cabin 4 and an engine 5 and a radiator 6 are disposed in the rear of the engine 5 and a radiator 6, and the lower part of one side of an inverted L-shaped grain tank 7 extending from the upper part of the engine 5 and the radiator 6 to the upper part of the threshing device 3 is provided. It is attached to the support frame 10 so as to tilt laterally around the discharge spiral 8. Further, in front of the threshing device 3, there is provided a pretreatment device 11 comprising a cutting device and a grain culm transporting device which rotate up and down around a rear part.

The fried cylinder 12 that is in communication with the transfer end of the first trough of the threshing device 3 and stands up and serves as a grain transfer device enters from the bottom plate of the grain tank 7 near the threshing device 3 and The throwing casing 13 having the throwing blades 13a installed therein is attached to the end thereof, and is vertically divided at a portion corresponding to the bottom plate, and when the hydraulic cylinder 15 is extended, the grain tank 7 is centered around the discharge spiral 8. When the hydraulic cylinder 15 is operated to reduce, the grain tank 7 descends and rotates to return to the horizontal position shown by the solid line. Then, the dividing portion of the fried food barrel 12 is connected.

In addition, as shown in FIG. 3, the dividing portion of the fried grain barrel 12 has a lower end (upper side in the grain transfer direction) at the lower end of the upper (lower side in the grain transfer direction) cylinder 12a. The upper end of the lower spiral shaft 16a of the transfer spiral 16 which is fitted to the outer periphery of the cylindrical body 12b and is housed therein has the lower cylinder through the bearing 17, the bearing holder 18 and the plurality of support arms 20. The threaded portion of the portion which is supported by 12b and protrudes upward from the bearing 17 is screwed with a nut 23 to which a taper pin 22 having an engaging pin 21 is fitted and welded on the peripheral surface is screwed. Is a cylindrical shaft, and the cylindrical connecting shaft 24 fitted and welded to the outer periphery of the lower end thereof has a projection 25 on the lower end surface for engaging the engaging pin 21, and the connecting pipe 26 fitted and welded to the outer periphery. The lower end is the upper taper of the nut 23. It is designed to be superposed on the surface.

The bearing holder 18 and the spacer 27 that fits on the inner circumference of the lower portion thereof and overlaps the lower surface of the bearing 17 have the same flat surface and project from the lower spiral shaft 16a. A support cup 29 fitted to the lower spiral shaft 16a at a lower portion of the flange 28 that supports the spacer 27 is welded to the lower transfer spiral 30 and the lower spiral shaft 16a, and the support cup 29 has a felt. A soft material 31 (made of rayon) is fitted and superposed on the lower surfaces of the bearing holder 18 and the spacer 27 to completely close the fitting gap between the two.

In the above-mentioned combine, when the machine body is moved forward while driving each part, the reaping device cuts the napped culms, and the culm conveying device supplies the culmed grain culms to the threshing device 3 while adjusting the handling depth. The threshing device 3 sandwiches and conveys the root part of the supplied grain stalks by the feed chain and the sandwiching rail, while the ears are threshing by the handling cylinder in the handling room, and the threshing leaked from the nets. The objects are subjected to wind selection and sieve selection, and the grain dropped into the first trough is pumped by the fried barrel 12 and put into the grain tank 7. At that time, the middle dividing parts of the fried food barrel 12 are connected as shown in FIG. When the grain tank 7 becomes full by continuing such cutting and threshing, the machine is moved to a transport vehicle such as a truck parked on the farm road, and the upper portion of the discharge auger 32 is raised and rotated. When the discharge port is exposed to the carrier bed and the discharge clutch is turned on, the discharge spiral in the discharge spiral 8 and the discharge auger 32 is rotated, and the shutter on the discharge spiral 8 is opened. The grains inside are discharged, discharged, and loaded on the loading platform.

When the discharge and loading of the grain progresses and the remaining amount of the hanging portion on the right side (see FIG. 2) when viewed from the rear of the grain tank 7 becomes small, when the hydraulic cylinder 15 is extended, Since the grain tank 7 tilts outward as shown by the chain line around the discharge spiral 8, the grain portion of the grain tank 7 extending onto the threshing device 3 flows down to the drooping side, and Since the bottom plate and the outer plate of the grain tank 7 are V-shaped with the discharge spiral 8 as the lowest point, the entire amount can be reliably pumped and discharged. At that time, the fried-grain barrel 12 rises together with the grain tank 7 at the dividing portion corresponding to the bottom plate of the grain tank 7, with the upper portion separated from the lower portion. When the grain discharge is completed, the hydraulic cylinder 15 is contracted to return the grain tank 7 to the position indicated by the solid line on the threshing device 3 side, and the lower end of the upper cylinder 12a is moved to the lower cylinder. It is fitted to the upper end of 12b, the tubular connecting shaft 24 is fitted to the taper pin 22, and the engaging pin 21 can overlap the protrusion 25.

When the grain is discharged from the sorting section of the threshing device 3 and is fed into the grain tank 7 by the fried cylinder 12, the feeding spiral is broken and the support arm 20 is traversed in the dividing section. As a result, the lifted grains tend to be pressed against the lower surfaces of the bearing holder 18 and the spacer 27, but the support cup 29 immediately below them has a diameter substantially the same as that of the bearing holder 18. Since the grain in the vicinity of the lower spiral shaft 16a is received and guided to the outside, debris mixed in the grain may enter from between the outer periphery of the lower surface of the bearing holder 18 and the upper end surface of the supporting cup 29. In such a state, since the lower surface between the inner circumference of the lower end of the bearing holder 18 and the outer circumference of the spacer 27 that performs clearance management is covered with the soft material 31, scraps and the like are described above. It does not enter the bearing 17.

[0013]

[Effect of device]

 According to the present invention, a transfer spiral is installed in a cylindrical body, and the transfer shaft of the transfer spiral 16 and the cylinder are intermittently divided in the middle thereof, and the end of the transfer shaft on the upstream side in the grain transfer direction is connected to the cylindrical body. The bearing 17 is supported via the supported support arm 20, the bearing holder 18, and the bearing 17, and the split portion of the transfer shaft is interlockably connected in a detachable manner. And the spacer 27 whose end surface is substantially flush with each other and is supported by the spacer 27, and slides the soft material 31 held by the support cup 29 mounted on the transfer spiral over the end surface of the bearing holder 18 and the spacer 27. Since the contacted grains are closed, the transferred grains are received by the support cups 28 and guided outward, and the soft material 31 is guided to the bearing holder 18 and the spacer 27. Combined with the fact that the gaps are covered in a polymerized state, it is possible to prevent the debris mixed in the grain from entering the bearing 17, and ensure a smooth grain transfer over a long period of time. You can continue lightly.
