The embodiment of the present invention to be described below is an extendable grain discharge tube connected to a Glen tank, and is an apparatus that allows an operator to easily perform an expansion / contraction movement operation manually.
Next, the best mode for carrying out the invention will be specifically described with reference to the drawings.

  First, as shown in FIG. 25, the combine 13 places the Glen tank 1 on the right side (forward direction) of the threshing device 15 mounted on the vehicle body 3 equipped with the crawlers 14, 14 molded from rubber. It is installed side by side and is configured to store and store the grain after threshing.

  The pre-harvest processing device 16 is provided on the front side of the control seat 17 disposed on the front side of the Glen tank 1 and the threshing device 15, and the cereals harvested as the vehicle body 3 moves forward are supplied to the threshing device 15. It is configured to be conveyed and supplied.

  And although the illustration of the Glen tank 1 is omitted, as is conventionally known, the end side of the discharge spiral in the front-rear direction axially mounted on the inner bottom portion of the tank is extended to the lower part of the milling cylinder 4. It is configured to be connected to the lower end portion of the cerealed helix so as to be able to transfer and transfer the grain and the rotational power.

  As shown in FIGS. 1 and 2, the telescopic grain discharge cylinder 2 has the movable conveyance cylinder 6 from the front end side along the outer periphery of the fixed conveyance cylinder 5 connected to the flocculation cylinder 4 on the vehicle body 3 side. It is slidably inserted and fitted, and can be expanded and contracted manually. The telescopic grain discharge cylinder 2 is shown in a contracted state in FIG. 1 and in an expanded state in FIG. In this case, as shown in the drawing, the fixed conveying cylinder 5 of the embodiment is connected to the upper part of the cerealing cylinder 4 by pivotally connecting the base part to the upper part of the cerealing cylinder 4 and extending the tip part outward. In the cylinder, a conveying spiral 18 having a starting end connected to the cerealing helix is internally provided, and the grain inherited from the cerealing cylinder 4 is conveyed to the tip side. Then, as described above, the movable transport cylinder 6 is configured to be freely slidably inserted from the front end side of the fixed transport cylinder 5 and to be extendable and contractable in the direction of the cylinder with respect to the fixed transport cylinder 5 by manual operation A grain outlet 8 is opened at the tip.

  As shown in FIGS. 1 and 2, the telescopic transfer spiral 7 is connected at its starting end to the terminal end of the transporting spiral 18 of the fixed transporting cylinder 5, and its terminal end is the tip of the moving transporting cylinder 6. It extends to the immediate front of the grain outlet 8 opened in the shaft, and is pivoted to transport the grain inherited from the transport spiral 18 to the grain outlet 8. It is configured to be stretchable. In this case, as shown in FIGS. 1 and 2, the telescopic transfer spiral 7 is a transmission angular axis that is slidably inserted from the front end side into the central axis 19 of the transport spiral 18 in the fixed transport cylinder 5. A plurality of single spirals are engaged with each other so as to be freely slidable and transmitable (configuration that is transmitted by a square axis in the rotational direction).

  As shown in FIGS. 3 and 4, the telescopic transfer helix 7 has the tip end portion of the transmission angular shaft 20 bearing above the grain discharge port 8 (the end portion) at the tip end portion of the movable transfer cylinder 6. The resonance prevention bearing 21 is provided on the near side from the position to support the bearing. As shown in FIG. 4, the resonance prevention stage 22 is configured such that the resonance prevention bearing 21 is supported by the frame of the grain outlet 8.

  With the above-described configuration, the resonance preventing bearing 21 reliably drives the transmission angle shaft 20 to prevent bending due to the shaft vibration when driven with the telescopic transfer spiral 7 extended, and generates vibration and noise. The bearing is characterized in that the transmission angle shaft 20 is smoothly driven.

  Then, as shown in FIG. 5, the transmission angular shaft 20 is inserted into an angular shaft drive bearing 23 provided at the end of the central shaft 19 on the fixed conveying cylinder 5 side so that the transmission can be transmitted freely. The bearing is supported. As shown in FIG. 5, the transmission angular shaft 20 has the base end surface in the most extended state, the end surface of the angular shaft driving bearing 23 on the conveying spiral 18 (center shaft 19) side and the angular axis. It is configured to maintain a relationship between the drive unit 24 (the transmission angle shaft 20 is slidably fitted with a square hole).

  Thus, the transmission angular shaft 20 is shortened to the state where it is retracted from the central shaft 19 of the conveying spiral 18 to the angular shaft drive bearing 23 side at the position where the telescopic transfer spiral 7 is most extended, and thus the weight is reduced by a short amount. There is a feature that the telescopic operation is lightened without interference with the central shaft 19.

  And as FIG.1 and FIG.2 shows, the mobile conveyance cylinder 6 which concerns on this proposal Example forms the continuous cylinder from one raw material, and since it is set as the structure which is not connected on the way, it is concentric. There is a feature that there is almost no twisting or distortion, and that the concentric state with respect to the fixed conveying cylinder 5 can be maintained and the expansion and contraction sliding can be performed smoothly.

  On the other hand, in the conventional movable transfer cylinder A, as in the conventional type shown in FIG. 6, the flanges F and F are welded to the joint between the base cylinder B and the tip cylinder C, respectively. Was configured to be connected with bolts. Therefore, as shown in a plan view in FIG. 6, the conventional movable transfer cylinder A is smoothly joined as the flanges F and F of the joint portion are not welded correctly and are distorted and joined, resulting in a bent cylinder with no heart. It has a defect that makes it difficult to stretch and slide.

Next, the seal 25 will be described.
First, as shown in FIG. 7 to FIG. 10, the seal 25 is provided on the outer periphery of the distal end portion of the fixed transport cylinder 5 and exhibits a seal function with the movable transport cylinder 6 that slides outside. The configuration is to let In this embodiment, as shown in FIGS. 8 and 9, the seal 25 has a felt material 26 arranged on the inner side when wound and a resin material 27 having countless protrusions on the outer periphery. In addition, the sewing machine stitch 28 is formed over the entire periphery. As shown in FIGS. 8 and 9, the seal 25 forms the felt material 26 in the thickness portion 26 a that is twice as large as the other portions within a certain range.

  As shown in FIGS. 7 and 9, the seal 25 is attached to the outer periphery of a bearing 29 provided at the tip of the fixed transport cylinder 5. At that time, the seal member 25 is twice as thick as the felt material 26. The length portion 26a is attached so as to be positioned in the lower fixed range of the fixed conveyance cylinder 5, and the movable conveyance cylinder 6 is configured to slide on innumerable protruding surfaces of the resin material 27 disposed on the outer periphery.

  The seal 25 configured as described above has the durability greatly improved by sewing the entire circumference (seam 28), and the backlash due to sliding is generated compared to the upper side, and the gap is not increased. By disposing the thickness portion 26a twice as large as the felt material 26 in a certain range on the lower side that can be easily formed, the leakage of wrinkles can be prevented.

  And the seal | sticker 25 can perform joining with the internal peripheral surface of the movable conveyance cylinder 6 which slides accurately by using the resin material 27 which arranged innumerable protrusion on the outer peripheral surface, and there is no permanent deformation, There is a feature that prevents the leak of the soot by reliably catching the soot to leak.

Next, the sliding roller 30 that pivots on the upper part of the bearing 29 provided at the tip of the fixed conveying cylinder 5 and guides the outer moving conveying cylinder 6 will be described.
First, as shown in FIGS. 11 and 12, the sliding roller 30 is pivoted by a horizontal shaft 31 on a bearing 29 provided at the tip of the fixed conveying cylinder 5, and the outer peripheral surface moves outward. It is formed in a circular arc shape along the inner peripheral surface of the conveyance cylinder 6 and is configured to support and guide the movable conveyance cylinder that slides in the cylinder direction. In this case, as shown in the drawing, the sliding roller 30 is configured to support the fixed conveyance cylinder 5 so that the movable conveyance cylinder 6 is concentric, and to support the portion to which the load is most applied.

  Therefore, the moving conveyance cylinder 6 is maintained concentrically by supporting the most heavy part by the sliding roller 30 on the fixed conveyance cylinder 5 side, and the sliding becomes smooth and the manual operation becomes light. Of course, there is an advantage that there are almost no gaps in the entire circumference and no problems such as soot leakage occur.

  As shown in FIGS. 13 and 14, the positioning roller 32 is pivoted on the base side of the sliding moving transport cylinder 6 and has a guide passage inner 33 formed outside the lower surface of the fixed transport cylinder 5. It is configured to roll and move. In this case, as shown in FIG. 14 of the embodiment, three rollers 32 are mounted on the entire circumference of the movable transfer cylinder 6, but only one lower part moves in the guide passage 33. It is. In the guide passage 33, as shown in FIG. 13, a groove through which the positioning roller 32 can pass (guide rods 34 are provided on both right and left sides) is formed, and a stopper pin 35 is formed at the end portion of the groove. Is provided so that the roller 32 is stopped and the movable transfer cylinder 6 can be stopped at the most extended position.

  As shown in FIGS. 15 and 16, the movable transport cylinder 6 is provided with a stopper device 37 having a buffer rubber 36 on the front receiving surface at the most contracted position on the lower surface base side of the fixed transport cylinder 5. It is configured to be attached and received at the end of reduction. In this case, when the positioning roller 32 rolls in the guide passage 33 and moves to the end point of the contracted position, the stop portion 38 hits the buffer rubber 36 of the stopper device 37 and stops. In the extended position, the positioning roller 32 hits the stopper pin 35 at the end portion of the groove and stops.

  In this way, when the movable transport cylinder 6 reaches the end points of both the most extended position and the most contracted position, the positioning roller 32 and the stopper pin 35, and the stop portion 38 and the stopper device 37, respectively. In this relationship, the vehicle is reliably stopped, the shock is received while being reduced, and the vehicle can be stopped reliably at both limit positions, so that the safety is maintained.

  And the expansion-contraction type grain discharge cylinder 2 which concerns on an Example is provided with the fixing device 39 which locks the movement conveyance cylinder 6 to the fixed conveyance cylinder 5 in the position shortened shortest, as shown in FIG. That is, as shown in the drawing, the fixing device 39 is provided with an engagement hook 40 on one fixed conveyance cylinder 5 side so as to freely rotate, and an engagement pin 41 is fixed to the base end portion of the other movement conveyance cylinder 6. In the position where the movable conveyance cylinder 6 is reduced to the fixed conveyance cylinder 5 side, the engagement hook 40 is rotated and engaged with the engagement pin 41 to be locked and fixed.

  Thus, as shown in FIG. 17, the telescopic grain discharge cylinder 2 is mounted on a truck or the like when traveling on the road or by combining the movable conveyance cylinder 6 to the fixed conveyance cylinder 5 by the fixing device 39. When transported, it is not locked and stretched reliably, and can be improved in safety.

Next, the handle 9 provided on the movable transfer cylinder 6 constituting the main part of the present invention, the fixing release tool 11 attached to the handle 9, and the fixing device 10 will be described.
First, as shown in FIG. 18 to FIG. 20, the support pipe 42 for fixing the handle 9 has its distal end portion (lower portion) extended downward and its base portion (upper portion) fixed to the lower side of the movable transfer cylinder 6. The mounting plates 43 and 44 are provided on both sides of the base, that is, on the expansion side and the reduction side of the movable transfer cylinder 6, respectively. As shown in FIG. 19, the support pipe 42 is provided with a long hole 45 formed in the vertical direction on the front side (the side on which the movable transfer cylinder 6 extends), and a torsion spring 49 is inserted into the support pipe 42 from the long hole 45. The upper part can be attached.

  Then, as shown in the drawing, the handle 9 presses a pair of left and right (shaped like the middle) handle members 9a (see FIG. 22) formed in the same shape so as to be pinched from both the left and right sides of the support pipe 42. Are fixed to the mounting plates 43 and 44 and integrally formed. In this case, the handle 9 fixes the upper part of the handle member 9a to the mounting plates 43 and 44 with screws from both sides as described above, and the lower part to fix the left and right handle members 9a with screws. It has a structure that is fixed in a single piece.

  As shown in FIG. 20, the handle 9 opens the dust dropping / tool insertion hole 46 at a position above the grip position of the pair of left and right handle members 9 a and falls from the upper fixing device 10. Can be discharged to the lower side, and further, the tool 47 is inserted from the lower outer side so that the bolt 48 can be removed and tightened.

  As shown in FIG. 20, the dust dropping / tool insertion hole 46 of the embodiment is fixed from the past when dust such as dust generated between the fixed conveying cylinder 5 and the moving conveying cylinder 6 accumulates in this portion. Although the brake force of the device 10 has been reduced, there is an advantage that the reduction of the brake force can be prevented by dropping the dust downward from the hole 46.

  Next, as shown in FIG. 18 to FIG. 20, the fixing device 10 has a fixing release tool, which will be described later, in a pressed state (see FIG. 18) and a released state with respect to the outer peripheral surface of the fixed transport cylinder 5 from the outside. 11 and the interlocking arm 50 can be operated. And the fixing device 10 can fix the movable transfer cylinder 6 that slides with respect to the fixed transfer cylinder 5 or release the fixing. In the case of the embodiment, as shown in FIG. The upper surface is formed in a circular arc shape so as to follow the outer peripheral surface of the fixed conveyance cylinder 5 by a rubber material.

  Accordingly, as shown in FIG. 21, the fixing device 10 can be pressed along the outer peripheral circular arc surface of the fixed conveying cylinder 5 at the time of fixing, so that the braking force is significantly larger than that of the conventional flat brake surface. It has the feature that it can be raised and the fixed position can be held securely.

Next, a description will be given of a related configuration of the fixing release tool 11, the interlocking arm 50, and the handle 9 of the fixing device 10.
First, as shown in FIGS. 19, 22, and 23, the unlocking tool 11 is formed by forming an operation arm 51 in an L shape on the upper part of the lever 11 a having a U-shaped cross section, Is attached to the upper portion of the support pipe 42 together with a torsion spring 49 so as to be freely rotatable. At the mounting position, the fixing release tool 11 is configured so that the tension pressure of the torsion spring 49 acts and the tension release force is always kept on the side where the tube 6 extends from the handle 9.

  As shown in FIGS. 20, 22, and 23, the interlocking arm 50 pivots the intermediate portion to the support portion of the movable transfer cylinder 6 and attaches the fixing device 10 to the tip portion with a bolt 48. The base is pivotally connected to the operation arm 51 of the fixing release tool 11 and is fixed. Then, as can be seen from the drawing, when the unlocking tool 11 is pressed against the handle 9 against the tension of the torsion spring 49 by the finger, the operation arm 51 is raised, and the interlocking arm 50 is moved to the intermediate portion. With the pivot P as a fulcrum, the fixing device 10 at the tip is released from the outer peripheral surface of the fixed conveying cylinder 5 to release the fixed state.

  Thus, when the fixing device 10 presses the lever 11a with a finger from the position where the fixing device 10 is in pressure contact with the outer peripheral surface of the fixed transport cylinder 5, it is released from the outer peripheral surface and becomes unfixed. It is a structure that can be extended and retracted. And in the case of this Example, the fixing device 10 is set as the structure which can be fixed in the steplessly favorite position in the middle position of the expansion-contraction sliding action of the movement conveyance cylinder 6. FIG. Then, as described with reference to FIGS. 13 to 16, the movable conveyance cylinder 6 has the buffer rubber 36 at the most contracted position within the range where the movable conveyance cylinder 6 expands and contracts with respect to the fixed conveyance cylinder 5. At the position where the stop portion 38 collides with the stopper device 37, or the position where the stopper 38 extends most, the fixed conveyance is performed between the position where the positioning roller 32 reaches the stopper pin 35 (the position before the bearing 29). The fixing device 10 can be held in a fixed state in pressure contact with the outer peripheral surface of the cylinder 5.

  Then, as shown in FIGS. 18 to 23, the fixing device 10 according to the embodiment presses against the outer peripheral surface of the fixed conveying cylinder 5 with the tension pressure of the torsion spring 49 acting via the interlocking arm 50. In this state, when a force in a contracting direction is applied to the movable transport cylinder 6, a fixing force (brake force) is strongly applied accordingly. Therefore, the telescopic grain discharge cylinder 2 has a feature that the movable transfer cylinder 6 can be reliably fixed to the fixed transfer cylinder 5 even when the operation is performed by raising the grain discharge port 8 up to the maximum angle during the koji discharging operation.

  Then, as shown in FIG. 24, the fixing device 10 can be tilted downward as shown in the drawing by removing the pivot pin P of the pivot arm P of the interlocking arm 50 already described, and the brake surface can be easily cleaned. The configuration can be made.

  Since the embodiment of the present invention is configured as described above, the operator sitting on the control seat 17 grasps the handle 9 and removes the fixing device 10 by finger operation, and pushes and pulls the handle 9 back and forth. Thus, the movable transfer cylinder 6 can be expanded and contracted. Therefore, the present invention has an advantage that the operation of the telescopic grain discharge tube 2 is easy and can be quickly expanded and contracted, and the workability can be further improved.

  In addition, in the case of an Example, as shown in FIG.1 and FIG.25, in front of the grain discharge port 8 in the front-end | tip part of the movement conveyance cylinder 6, the fixing release tool 11a and discharge clutch lever 55 for auxiliary workers are provided. Both are provided so that they can be linked and operated from the work position.

  In the embodiment of the present invention, the movable conveying cylinder 6 can be freely and continuously fixed at any position within the expansion / contraction range. There is no need to move back and forth to make it easier to work.

  In the embodiment of the present invention, since the fixing surface of the fixing device 10 is formed in an arc shape along the outer peripheral surface of the fixed conveying cylinder 5 by a rubber material, the entire surface can be pressed and the brake area can be greatly increased. However, the braking force is increased.

  In the embodiment of the present invention, as shown in FIG. 6, in order to lengthen the moving conveyance cylinder A, the flanges F and F were welded to the two cylinders B and C made separately to be bolted. Compared to the conventional configuration, since the flange is joined by welding and is formed as a continuous single-piece cylinder 6, it is concentric, almost free of twisting and distortion, and concentric with the fixed conveyance cylinder 5. It is possible to smoothly extend and slide while maintaining the state.
