Description

  The present invention relates to a combine, and more particularly, to a technique for preventing interference and approach between an exhaust device and a discharge auger piped on the upper part of a combine body.

  Conventionally, an exhaust device for a combine is piped from the engine to the rear side of the fuselage through the lower part of the fuselage, and exhaust gas generated by the engine is discharged behind the fuselage. The exhaust device includes an exhaust silencer that reduces exhaust noise, a tail pipe that exhausts exhaust gas, and the like (see, for example, Patent Document 1).

  However, when an exhaust device such as an exhaust silencer or a tail pipe is piped at the lower part of the machine body, mud or the like wound during traveling tends to be applied to the exhaust device. When mud or the like is applied to the exhaust device, mud or the like may be trapped and adhered to the exhaust silencer or the tail pipe, or mud or the like may enter the tail pipe. In particular, when the combine travels in a wet field, a large amount of mud or the like adheres to the exhaust device, and the intrusion of mud or the like into the exhaust device also increases, resulting in a decrease in the travel performance of the combine.

  For this reason, a combine in which an exhaust device is piped on the upper part of the fuselage has been developed. As a combine equipped with such an exhaust device, for example, an exhaust silencer is provided in the engine room, and a tail connected to the exhaust silencer is provided. A combine has been developed in which a pipe is provided above the fuselage and the rear part of the tail pipe is fixed to the upper part of the threshing part. Also, an exhaust pipe from the engine is installed above the fuselage, an exhaust silencer connected to the exhaust pipe is fixed to the upper part of the threshing section, and a combine in which a tail pipe is connected to the exhaust silencer has also been developed. Yes.

  According to the combine in which the exhaust device is piped on the upper part of the fuselage as described above, it is difficult for mud or the like wound up during traveling to get caught in the exhaust device, mud etc. Is prevented from entering. For this reason, it is possible to prevent a drop in the traveling performance of the combine due to the inclusion of mud or the like in the exhaust device or the intrusion of mud or the like.

On the other hand, there is conventionally known a combine tank equipped with a grain tank for storing grain and a discharge auger for transferring the grain in the grain tank to a truck bed etc., and the discharge auger can be raised and lowered in the vertical direction. It is configured to be able to turn left and right, and the use position of the discharge auger is set in advance, and it automatically returns to the position of the auger rest after use. A combine with an auto-return function for mounting and fixing is also known.

  However, in the case of a combine in which the exhaust device is piped on the upper part of the fuselage, a part of the exhaust device protrudes above the combine. In addition, it is necessary to set the tail pipe to a certain height so that the tail pipe is not covered with sawdust or crops. Therefore, if the discharge auger is raised and swung carelessly, the exhaust device and the discharge auger interfere with each other, and both may be deformed or damaged.

  In addition, when the exhaust device is a combine that is piped at the top of the fuselage, the exhaust auger can be used by swiveling the exhaust auger close to the exhaust port of the tail pipe to a position where it hits the exhaust gas. There is also a problem that the surface of the discharge auger tends to become dirty.

An intake path is formed. The intake path is connected to the engine 35, and outside air taken in via the intake path is used for combustion in the engine 35.

  Next, the exhaust device 41 will be described. As shown in FIG. 4, the exhaust device 41 is connected to the exhaust manifold 36 of the engine 35, and exhausts exhaust gas generated by the engine 35 while reducing the exhaust noise. The exhaust device 41 includes an exhaust pipe 42, an exhaust silencer 43, and a tail pipe 45.

  The exhaust pipe 42 is connected to the engine 35 and guides the exhaust gas from the engine 35 to the upper side of the fuselage 13. The exhaust pipe 42 has an overall shape as shown in FIGS. It extends toward the rear of the fuselage 13 from the upstream end that is connected to the exhaust manifold 36 of the engine 35, bends toward the left side of the fuselage 13 on the engine 35, and then the rear of the fuselage 13.

  Next, the discharge auger 21 will be described. As shown in FIG. 1, the discharge auger 21 has a longitudinal feed auger 22 and a lateral feed auger 23. As shown in FIG. 7, the base side of the lateral feed auger 23 is connected to the upper part of the vertical feed auger 22 so as to be rotatable in the vertical direction. A bracket 55 projects from the side of the vertical feed auger 22, and a bracket 56 projects from the side of the lateral feed auger 23. One end of a cylinder 51 as a vertical driving means is rotatably attached to the bracket 55, and the other end of the cylinder 51 is rotatably attached to the bracket 56. Due to the expansion and contraction of the cylinder 51, the discharge auger 21 is lifted up and down. Further, the transverse feed auger 23 is provided with a rotary potentiometer 53 as a vertical angle detection means, and the rotary potentiometer 53 detects the vertical angle of the discharge auger 21.

  As shown in FIG. 7, a spur gear 57 is fitted and fixed to the middle part of the longitudinal feed auger 22. An actuator 52 serving as a horizontal direction driving unit is provided on the machine body 13 side, and a spur gear 58 is provided on the rotation shaft of the actuator 52. The spur gear 57 and the spur gear 58 are engaged with each other, and when the actuator 52 is operated, the longitudinal feed auger 22 and the lateral feed auger 23 integrally rotate in the horizontal direction. A rotary potentiometer 54 as a horizontal angle detecting means is provided coaxially with the spur gear 58. The horizontal angle of the discharge auger 21 is detected by the rotary potentiometer 54. The vertical angle detecting means and the horizontal angle detecting means can use rotational angle detecting means such as a resolver and a rotary encoder in addition to a rotary potentiometer.

  Next, the discharge auger operating means disposed in the cabin 31 will be described. A discharge auger control panel 61 is provided on the side of the seat 32 disposed in the cabin 31. As shown in FIG. 8, a discharge auger manual operation lever 62, a set dial 63, an auto set switch 64, an auto return switch 65, and the like are disposed on the top surface of the discharge auger control panel 61.

  The discharge auger manual operation lever 62 is configured to be tiltable in four directions, front, rear, left and right. By manually operating the discharge auger manual operation lever 62, the cylinder 51 as the vertical drive means and the actuator 52 as the horizontal drive means are actuated to raise and lower the discharge auger 21 in the vertical direction. And a horizontal turning operation.

  The set dial 63 is used for auto-setting the discharge auger 21 in combination with the auto-set switch 64. The discharge auger 21 can be automatically raised and swung to a preset target position by auto-setting. The set dial 63 is for setting the target position. When the auto-set switch 64 is pressed, the cylinder 51 and the actuator 52 are operated, and the discharge auger 21 reaches the target position with the longitudinal auger 22 as the center. Automatically rise and fall.

  The auto return switch 65 is used at the end of the grain discharging operation by the discharging auger 21. When the auto return switch 65 is pressed, the cylinder 51 and the actuator 52 are operated, and the discharge auger 21 is automatically raised and swung and placed on the auger rest 25.

  As shown in FIG. 9, a discharge auger controller 71 as a control means is provided to control the elevation and turning of the discharge auger 21. The discharge auger controller 71 includes a cylinder 51 as the vertical drive means and a horizontal drive means in manual operation of the discharge auger manual operation lever 62 and up and down and turning of the discharge auger 21 such as auto setting and auto return. The actuator 52 is controlled. The discharge auger controller 71 is mainly composed of a CPU 72 and a data storage unit 73. The CPU 72 uses the detection signals of the rotary potentiometer 53 as the vertical angle detector and the rotary potentiometer 54 as the horizontal angle detector as one input signal.

  The data storage unit 73 stores data relating to manual operation of the discharge auger 21, auto-setting and auto-return, and data considering interference between the exhaust device 41 and the cabin 31 of the combine 11 and the discharge auger 21. As shown in FIGS. 1 and 4, the tail pipe 45 and the cabin 31 of the exhaust device 41 piped on the upper part of the fuselage 13 of the combine 11 are above the height of the discharge auger 21 when mounted on the auger rest 25. Therefore, when the discharge auger 21 is housed and rotated in the auger rest 25, or when it is rotated to the discharge position, there is a possibility of interfering with the tail pipe 45 and the cabin 31. Further, regarding the exhaust silencer 43 and the like below the augerest 25, the discharge auger 21 can be lifted and swung in a region lower than the augerest 25 when the discharge auger 21 is detached from the augerest 25. There is a possibility that the auger 21 and the tail pipe 45 may interfere with each other. Therefore, the vertical and horizontal angles of the discharge auger 21 corresponding to positions that may interfere with the exhaust device 41 and the cabin 31 are obtained, and the data of the vertical and horizontal angles is stored in the data storage unit 73. In this embodiment, an EEPROM (Electrically Erasable and Programmable Read Only Memory: a kind of nonvolatile semiconductor memory, which is a read-only storage device capable of electrically writing contents) is used as the data storage unit 73. A ROM or other storage medium may be used.

  According to the discharge auger controller 71 configured as described above, the discharge auger 21 is stored in the input signal and data storage unit 73 that is continuously input from the rotary potentiometers 53 and 54 while the discharge auger 21 is swung up and down. Based on the obtained data, the CPU 72 performs arithmetic processing related to manual operation, auto-set, and auto-return. When it is detected that the position of the discharge auger 21 is a position that may interfere with the exhaust device 41 and the cabin 31, the CPU 72 generates a control signal for automatically raising or stopping the discharge auger 21. The output auger 21 is automatically raised or stopped to avoid interference with the exhaust device 41 and the cabin 31.

  If the discharge auger 21 is made accessible to the exhaust port 46 of the tail pipe 45 and can be lifted and swung to the position where the exhaust gas from the exhaust port 46 hits, soot contained in the exhaust gas can easily adhere to the discharge auger. As a result, the surface of the discharge auger is likely to become dirty. Therefore, in addition to the above data, the vertical angle and horizontal angle of the discharge auger 21 corresponding to the position where the exhaust gas from the exhaust port 46 may hit is obtained, and the data of the vertical angle and horizontal angle are stored in the data storage unit 73. You may make it memorize. In this case, when it is detected that the position of the discharge auger 21 is a position that may hit the exhaust gas from the exhaust port 46, the CPU 72 generates a control signal for automatically raising or stopping the discharge auger 21. The discharge auger 21 is automatically raised or stopped to prevent the discharge auger 21 from approaching the exhaust port 46 of the tail pipe 45.

  In the description of the first embodiment, the combine 11 that protrudes upward has been described in which the height of the tail pipe 45 of the exhaust device 41 is higher than the height of the discharge auger 21 when the tail pipe 45 is placed and fixed on the auger rest 25. However, as shown in FIGS. 10 and 11, the present invention is applied even to the combine 11 in which the height of the tail pipe 45 is lower than the height of the discharge auger 21 when the tail pipe 45 is placed and fixed on the auger rest 25. Can do.

  That is, in the combine 11 shown in FIGS. 10 and 11, when the discharge auger 25 is detached from the auger rest 25, the discharge auger 25 can be raised and swung in a region lower than the auger rest 25. There is a possibility of interference with the pipe 45 or the exhaust silencer 43. Therefore, even if the combine 11 is lower than the height of the discharge auger 21 when the height of the tail pipe 45 is placed and fixed on the auger rest 25, the discharge auger corresponding to a position that may interfere with the exhaust device 41. By obtaining the vertical angle and horizontal angle of 21 and storing the vertical angle and horizontal angle data in the data storage unit 73, interference between the exhaust device 41 and the discharge auger 25 can be avoided.

  Next, the combine 11 which concerns on Example 2 of this invention is demonstrated. The second embodiment is greatly different from the first embodiment in that a guard member 81 is provided above the fuselage 13 of the combine 11. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 12, a guard member 81 is provided above the fuselage 13 of the combine 11. The guard member 81 is a member that abuts the discharge auger 21 when the discharge auger 21 approaches the tail pipe 45 and prevents interference between the tail pipe 45 and the discharge auger 21. As for the mounting position and shape of the guard member 81, the vertical and horizontal angles of the discharge auger 21 corresponding to the position where the guard member 81 may interfere with the tail pipe 45 are obtained. Before invading, the lateral feed auger 23 is in a position and shape where it abuts against the guard member 81 before the tail pipe 45.

  Specifically, as shown in FIGS. 12 and 13, the guard member 81 of this embodiment includes a guard member main body 82 in which a metal pipe is bent in a substantially inverted U shape so that the open side is down, The guard member main body 82 includes a support body 83 that supports the guard member main body 82 from behind, and the guard member main body 82 and the support body 83 are connected by welding means. Further, a mounting base (not shown) is provided at the lower ends of the guard member main body 82 and the support body 83, and the guard member 81 is mounted by fixing the mounting base above the machine body 13. The guard member main body 82 is formed so as to surround the exhaust device 41 when viewed from the front (more precisely, as viewed from the front connecting the tail pipe 45 and the longitudinal feed auger 22). Be placed. However, it is also possible to arrange it at the side of the exhaust device 41 or in front of it.

  In the configuration as described above, even if the turning operation of the discharge auger 21 is mistakenly operated, the discharge auger 21 comes into contact with the guard member 81, the turning of the discharge auger 21 is stopped, and the exhaust auger 41 comes into contact. Absent. That is, interference between the exhaust device 41 and the discharge auger 21 can be prevented. In addition, you may provide a buffer member around the guard member 81, and the guard member 81 can be reduced in size by attaching it close to the longitudinal feed auger 22.

  Further, in order to prevent the exhaust auger from being contaminated by the exhaust gas, the vertical angle and horizontal angle of the exhaust auger 21 corresponding to the position where the exhaust gas from the exhaust port 46 may hit are obtained. The lateral feed auger 23 may contact the guard member 81 before the discharge auger 21 enters at a horizontal angle.

  In the description of the second embodiment, the combine 11 that protrudes upward has been described in which the height of the tail pipe 45 of the exhaust device 41 is higher than the height of the discharge auger 21 when the tail pipe 45 is placed and fixed on the auger rest 25. However, even if the combine 11 (see FIGS. 10 and 11) is lower than the height of the discharge auger 21 when the height of the tail pipe 45 is placed and fixed on the auger rest 25, the exhaust device 41 and the discharge auger 25. Therefore, the present invention can be applied. By providing the guard member 81 according to the present invention above the body 13 of the combine 11, interference between the exhaust device 41 and the discharge auger 25 can be prevented.

  In addition, an Example is not limited above, For example, you may change as follows.

  After providing the guard member 81 that protects the exhaust device 41, the operation of the discharge auger 21 may be controlled so that the discharge auger 21 does not interfere with the guard member 81. With this configuration, even when the discharge auger controller 71 malfunctions, the discharge auger 21 contacts the guard member 81 and does not contact the exhaust device 41 and is not damaged.
