JP 11-332363 A

  The remote control unit needs to be moved obliquely along the inclined top plate portion of the work machine cover to perform the attaching / detaching operation from the holder. At this time, the remote control unit is pulled out against the suction force of the suction means. It is necessary and the operation of attaching / detaching the remote control unit is troublesome.

  In addition, the remote control unit is a mechanism that is sucked by the suction means when mounted on the holder and stably holds against vibration of the auger tip during movement of the discharge auger and body vibration during cutting operation. However, since the stable holding is constituted by a magnet attracting means, the attracting force by the magnet is lowered due to secular change, and durability and reliability are not sufficient.

  Therefore, the present invention makes the remote control unit abut on the bottom support portion and the front, back, and side holding portions, and engages the locking portion of the holder with the concave portion serving as the grip portion on the rear surface of the remote control unit. An object of the present invention is to provide an auger operating device in a combine that solves the above-described problems by stably holding a remote control unit in a holder.

The present invention provides an operating device having a remote control unit (31) removably held by a holder (30).
The case (40) of the remote control unit is such that when the operator holds the remote control unit by hand on the back surface thereof, the concave portion (40b) serving as a guide for the gripping position of the remote control unit crosses in the lateral width direction of the case. Formed,
The holder (30) includes a bottom support part (g, h) that can support the bottom surface of the remote control unit, a front surface holding part (i, j) that can contact the front surface of the remote control unit, and a back surface of the remote control unit. Left and right lateral directions so as to be able to come into contact with the back holding part (e, f) that can come into contact, the side holding part (k, l) that can come into contact with the left and right side surfaces of the remote control unit, and the recess (40b) of the remote control unit And the bottom support part (g, h), the front support part (i, j), the back support part (e, f), and the side support part. (K, l) and the locking portion (m) are formed by bending one wire (35),
When the remote control unit (31) is inserted into the holder (30), the concave portion (40b) is engaged with and held by the locking portion (m).
It is in the operating device characterized by this.

  The front holding portion (i, j) of the holder (30) is configured so that each of the operation switches (A, B, C, D, E) on the front surface of the remote control unit is in a state where the remote control unit (31) is held by the holder. , F, G, M, N) are arranged at positions that do not cover.

  In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it does not have any influence on the structure described in the claim by this.

  According to the first aspect of the present invention, the bottom surface, the front surface, the back surface, and the side surface of the remote control unit are in contact with the bottom surface support portion, the front surface holding portion, the back surface holding portion, and the side surface holding portion of the holder, and on the back surface of the remote control unit. The holder's locking part engages with the formed concave part to be held and is mechanically held by the elastic force of the holder, so it can be held stably by the vibration of the airframe or auger tip. It can be easily attached and detached by inserting and removing it from the holder against the elastic force, can improve the usability of the remote control unit, and can be used with high reliability over a long period of time. .

Further, since the holder is formed by bending one wire, it can be manufactured with a simple configuration at low cost.

According to the second aspect of the present invention, since the front holding portion of the holder is disposed at a position that does not cover each operation switch on the front surface of the remote control unit, the operation switch is erroneously operated when the remote control unit is detached from the holder. In addition, each operation of the remote control unit can be performed with the remote control unit mounted on the holder.

A horizontal auger 17 is connected to the tip of the vertical auger 16 to constitute a grain discharge auger 19. The base part of the vertical auger 16 is rotatably supported, and the cylindrical part is rotationally driven by the auger turning motor 20. The base of the horizontal auger 17 is connected to the tip of the vertical auger 16 so as to be swingable in the vertical direction, and is driven up and down by the auger lifting cylinder 24.

  The vertical auger 16 and the horizontal auger 17 are fitted with a spiral in a cylindrical portion. When the discharge clutch is turned on, the rotation of the engine is transmitted to the horizontal spiral, and further transmitted to the vertical auger 16 and the spiral of the horizontal auger. . By turning the vertical auger 16 by the turning motor 20, the horizontal auger 17 is turned to a predetermined turning angle and is also raised and lowered to a predetermined angle by the auger lifting cylinder 24, and the distal end portion 17 a of the horizontal auger 17 becomes a predetermined position. Is operated as follows. The grain stored in the grain tank 7 is conveyed to the vertical auger 16 by the horizontal spiral, and further from the auger tip 17a set at a predetermined position by the grain discharge auger 19 including the vertical auger 16 and the horizontal auger 17. It is discharged to a truck.

  As shown in detail in FIGS. 2 and 3, the auger tip portion 17 a is formed with an opening 21 a opened downward at the tip portion of the tubular portion 21, and transparent vinyl or the like is used to surround the opening. A guide cover 22 is provided. Further, an auger flap (shutter) 23 is disposed in the opening 21a so as to be opened and closed by a pivot 23a. The auger flap 23 controls the discharge of the grains conveyed by the spiral 17b of the lateral auger 17. A synthetic resin cover 25 is integrally fixed to a side surface of the tubular portion 21 of the auger tip 17a. Inside the cover, a drive motor for the auger flap 23, a potentiometer for detecting the position of the flap, and an auger are provided. A camera 26 is built in. A camera 27 (see FIG. 1) is also arranged behind the traveling machine body 3, and the grain discharge state by the auger camera 26 and the rear state by the camera 27 are provided in the upper part of the cabin 10 of the driver seat 6. It is displayed as an image on the liquid crystal monitor 29 (see FIG. 1).

  A remote control holder 30 is installed on the distal end surface of the tubular portion 21 of the auger distal end portion 17a, and a wired remote control (remote control) unit 31 on the auger distal end side as an operation device is detachably disposed in the holder 30. Has been. The wiring from the remote control unit 31 extends along the upper part of the horizontal auger 17 together with the wiring from the device in the cover 25 and is connected to the control unit in the traveling machine body 3 together with the wiring from the driver side remote control unit 15. . Operation signals from the auger tip side and driver side remote control units 31 and 15 are appropriately output by the control unit to the auger turning motor 20, the auger lift cylinder, the discharge clutch control motor, and the auger flap drive motor.

  As shown in FIGS. 4 to 6, the auger tip side remote control unit 31 is detachably held in a remote control holder 30 formed by bending one wire 35. The remote control holder 30 hangs down in parallel with the longitudinal direction from both end portions a and b of the wire 35, the distance between both ends is narrow (c, d) on the distal end side, and it is bent forward and away from each other in the middle. Widened (e, f). The wire rods 35 and 35 are bent so as to extend forward to form the bottom surface support portions g and h, and further bent upward and extend obliquely upward (i, j) in a direction away from each other, at a predetermined upper position. Then, they are bent backward (k, l) and extend laterally to each other in front of the lower portions of the tips a and b of the wire 35 (m). The rearwardly bent portions k and l serve as side surface holding portions that restrict the left and right side surfaces of the remote control unit, and the obliquely upward portions i and j serve as front surface holding portions that regulate the front surface of the remote control unit. The intermediate connecting portion m extending in the direction serves as a locking portion, and the parallel wide portions e and f serve as a back surface holding portion that supports the back surface of the remote control unit. An interval p (see FIG. 11) between the both side surface holding portions k, l is set to be slightly wider than the left and right widths of the case of the remote control unit 31 formed of a flat and substantially rectangular parallelepiped (vertically long shape). The gap q between g and h is 30 to 40% of the left-right width of the remote control case, and is slightly wider than the diameter of the connecting portion 36a of the cord 36 extending from the remote control unit. The distance s between the front surface holding portions i, j and the back surface holding portions e, d (see FIG. 12), that is, the length of the rear-facing bottom surface supporting portions g, h is equal to or slightly wider than the thickness of the remote control case. . Further, the distance u (see FIG. 12) between the front surface holding portions i, j and the locking portion m, that is, the length of the rearward bent portions k, l is substantially equal to or slightly wider than the thickness of the remote control case. Therefore, it is slightly shorter than the interval s between the front surface holding portion and the back surface holding portion, and is substantially equal to the thickness of the concave portion 40b of the remote control case. The tip b of one wire 35 is bent so as to approach the other tip a, and the tips a and b are at a position higher by a predetermined amount t than the intermediate portion m (see FIG. 11).

  The holder 30 may use the wire 35 as it is on the metal surface, but may also use the wire 35 coated with rubber (dipping), and in this case, the friction force of the holder's rubber coating may be used. The remote control unit can be securely held in the holder.

  As shown in FIGS. 7 to 10, the remote control unit includes a case 40 and a switch base built in the case. The remote control case 40 is formed of a flat rectangular body having a vertically long shape, and a cord 36 extends from one short side thereof via a connector 36a. The case 40 is formed with uneven portions on the left and right side surfaces to prevent slipping when the remote control unit is gripped, and on the back surface, a guideline for the grip position of the remote control unit at a symmetrical position with respect to the vertical center line. Concave portions 40b and 40b are formed at two locations on the top and bottom.

The case 40 of the remote control unit 31 is composed of a split case, and the front and rear split cases 40 ₁ and 40 ₂ (see FIGS. 9 and 12) are integrally fixed with a rubber seal 40a interposed therebetween. . The rubber seal 40a is a predetermined amount of projection on the outer periphery of the split case 40 _1, 40 _2, and becomes a side from irregularities, when wearing the remote control unit 31 to the holder 30, the friction of the rubber seal 40a By force, the remote control unit can be more securely held in the holder. Further, a protrusion 40 d having a strap hole is formed at the upper left corner of the remote control unit 31. The protrusion 40d prevents the remote control unit 31 from being inserted back into the holder 30.

  Further, as shown in FIGS. 7 and 10, a plurality of push button switches and indicator LED lamps on the switch base are exposed on the surface of the case 40. At the center position in the vertical direction of the case, there is a first switch group 41 having a central switch A and switches B, C, D, and E in the shape of a cross on the upper and lower sides and left and right sides, and one of the upper and lower sides close to the switch group 41. The second switch comprises two switches F and G arranged on the short side of the left and right, an indicator lamp H of the switch, and three indicator lamps J, K and L arranged side by side on the short side. A switch group 42 and a third switch group 43 including two switches M and N arranged on the short side of the other upper and lower sides of the first switch group 41 are provided. A cord 36 extends from the other short side 40c on the side where the third switch group 43 is located.

  A display (design) sheet 45 is attached to the surface of the case 40 as shown in detail in FIG. Thereby, the remote control unit 31 corresponds to the third switch group 43 below the case with the open (M) and close (N) switches of the auger flap 23, and the first switch group 41 at the center of the case corresponds to the automatic auger. The swivel / storage switch (A), the manual up and down switches (B, C), the left turn and right turn switches (D, E) correspond to the second switch group 42 above the case, and the discharge switch (F ), The selection switch (G) and its indicator lamp (H), and the left (J), rear (K) and right indicator lamps (L) which are the selected positions of the auger.

  The up / down and left / right switches (B, C) (D, E), which are the cross switches of the first switch group 41 located at the center of the case in the vertical direction, move the position of the tip of the discharge auger 19 up, down, left and right. The switch (A) at the center is an automatic turning switch, and the operation of the automatic turning switch switches the turning to the discharge position of the auger and the automatic turning of the storage position for each operation. A switch (G) on one side of the second switch group 42 above the manual operation switch serves as a selection switch for selecting the discharge position of the discharge auger, and the auger discharge position is changed every time the selection switch is operated. The left and right sides and the right side of the machine are sequentially switched, and each discharge position is indicated by an indicator lamp (J, K, L). The switch (F) on the other side of the second switch group serves as a grain discharge switch for operating the operation (drive) and non-operation (stop) of the discharge auger, and the engine is rotated every time the discharge position is operated. The clutch operating motor that transmits or cuts power to the horizontal spiral and each spiral of the grain discharge auger 19 is operated, and the discharge or stop of the grain is displayed by the indicator lamp (H). In addition, each switch (M, N) of the third switch group 43 below the manual operation switch becomes an open / close switch for opening / closing the discharge port of the discharge auger, and the auger flap drive motor is moved in the forward / reverse direction. To drive.

  In the above description, the auger tip-side remote control unit 31 and its holder 30 connected to the auger tip are described. However, the driver-seat-side remote control unit 15 and its holder arranged in the auger operating device 13 of the driver seat 6 are described. In addition, the same one can be used.

  As described above, the remote control unit 31 is held by the holder 30 with the cord 36 facing downward, as shown in FIGS. 5 and 6 and FIGS. 10 to 12. At this time, the front surface of the remote control case 40 is in contact with the front surface holding parts i and j of the holder, the lower part of the back surface is in contact with the back surface holding parts e and f, and the left and right side surfaces are in contact with the side surface holding parts k and l. The bottom surface is supported by the bottom support portions g and h of the holder and is held by the holder 30. Further, the intermediate connecting portion (locking portion) m of the holder 30 abuts and engages with the finger-holding upper concave portion 40b on the back surface of the remote control case 40 while being slightly elastically deformed, so that the remote control unit 31 is stably held. Is done. At this time, the remote control unit 31 mounted on the holder is in a position where the front surface holding portions i and j do not cover the switches and indicator lamps (A to L) on the front surface. Further, the front surface holding portions i, j extend in directions away from each other, and when the remote control unit 31 is inserted into and extracted from the holder 30, the front surface holding portions i, j are connected to the respective switches A, B, C, D, E, F, G, M, and N are not touched, and the remote control unit is not erroneously operated. It is also possible to operate each switch while the remote control unit 31 is mounted on the holder 30.

  When the combine 1 is steered and the grains in the grain tank 7 are transferred to a truck or the like, the remote control unit (driver seat side 15 or auger tip side 31) is removed from the holder 30 and the remote control unit is removed. Operate the unit. In the remote control unit operation, the auger discharge position is selected by the selection button G in the relationship between the combine and the track. The selection button G is positioned above the selection button G and is checked by the indicator lamps J, K, and L without being disturbed by the finger operating the button, while the discharge position (left, rear, right) is confirmed. Operated. With the discharge position selected, the automatic turning button A is pressed to turn the auger 19 left and right and swing up and down to move the auger tip 17a to the selected position above the track.

  Even when the auger tip 17a is moved to the discharge position selected by the automatic turning button A, the auger tip discharge port 21a is unlikely to coincide with the discharge position of a track or the like. Adjust the position of the auger tip discharge port by ~ E). At this time, the operator holds the index finger in the upper concave portion 40b, holds the remote control unit 31 with one hand, and operates the automatic turning switch A and the manual operation switches (B to E) with the thumb. Since it is located at the center of the cross-shaped manual operation switches (B to E), the thumb can be easily and reliably transferred from the automatic turning switch A to the vertical and left and right manual operation switches B to E without checking the hand. Can be operated.

  Further, since the concave portion 40b serving as a guide for the gripping position is disposed between the manual operation switch raising switch B and the left and right turning switches D and E, the operator uses the index finger holding the concave portion 40b as a reference. Can sensuously recognize the position of each switch of the remote control unit, in particular, the automatic turning switch and the manual operation switch. As described above, since the operation of the discharge auger 19 can basically be performed by holding the remote control unit 31 with one hand, the operator can perform hydration with the free hand, for example, by one person. However, both hands of the operator are blocked during the cutting operation, but other operations such as hydration can be performed during the grain discharging operation, and an efficient combine operation can be performed continuously.

  Then, the auger 19 is operated by operating the discharge button H by the remote control unit 31 (15), and the auger flap 23 is opened by the flap opening button H to discharge the grain. The auger flap (shutter) may be automatically operated in conjunction with the open position by operating the discharge button (F).

  Then, as the transfer of the grain to the truck proceeds and the grain piles in the truck are leveled, the assistant uses the remote control unit 31 to use the auger manual operation buttons (C, B, E, The auger tip is moved left and right or up and down by D), and the grain discharge and discharge directions are appropriately operated by the flap open / close buttons (N, M). When the truck is full or the glen tank is emptied and the grain discharging operation by the auger is stopped, the kernel is operated by operating the discharge button (F) of the remote control unit 31 and the flap closing button (N). After stopping discharging, the auger 19 is moved to the storage position by pressing the automatic turning button (A).

  The grain discharging operation by the discharging auger may be performed by the combine driver and the assistant working together by the auger tip side remote control unit 31 and the driver seat side remote control unit 15. In addition, the remote control unit may be disposed only on either the auger tip side or the driver's seat side, and the remote control unit is not limited to a wired one but may be a wireless one, and is further embedded in the ohmic rest. It may be anything. Furthermore, the operation device including the remote control unit according to the present invention is not limited to the operation of the grain discharge auger, and may be applied to other operations.
