  The pair of left and right feeding roll drive shafts 21 and 21 are configured to be interlocked by bevel gears 24 and 24 groups to motor interlocking shafts 23 and 23 that are orthogonal to each other. One of the motor interlocking shafts 23 and 23 is coupled to the motor drive shaft 26 of the feeding roll drive motor 25 by coupling, and the motor interlocking shafts 23 and 23 are interlocked by an interlocking mechanism 27 using a chain and a sprocket. The feeding roll drive motor 25 is configured to be linked to forward / reverse switching.

  Clutch means 28 and 28 are provided between the motor interlocking shafts 23 and 23 and the left and right roll drive shafts 21 and 21 to transmit the rotation of the motor interlocking shaft 23 to the left roll drive shaft 21 or The clutch means 28, 28 can be switched to the non-driving state and the rotation of the motor interlocking shaft 23 can be transmitted to the right roll driving shaft 21 or switched to the non-driving state. The boom spray levers 29 and 29 can be operated separately.

  The transmission structure composed of the motor interlocking shaft 23, the bevel gear 24 group, the clutch means 28, and the roll drive shaft 21 employs a transmission configuration in which the left and right groups are arranged in the plan view, so that the transmission structure is more symmetrical. This is to prevent incorrect assembly.

  The through cylinders 30 and 30 are respectively located below the pair of feeding devices 11 and 11, and one end of each of the through cylinders 30 and 30 is communicated with the blow cylinder 31 provided with the blower 12. The other end on the downstream side is configured to communicate with the first jet tube 13. If it demonstrates in detail, the air blower 12 will be located in the rear part side of 2 riding management machines, and the ventilation cylinder 31 will be arrange | positioned in the front-back direction. The front end of the blower cylinder 31 branches left and right and communicates with the through cylinders 30 and 30. The blower 12a of the blower 12 receives power from an unillustrated PTO shaft on the fuselage side and rotates at high speed to generate wind, and the blast flows through the blower cylinder 31 and symmetrically bisects the cylinders 30, 30 The granular material that enters and is fed is conveyed by the blast, and the granular material reaches the subsequent first jet tube 13. An air volume adjusting valve (not shown) is provided in the middle of the blower cylinder 31 so that the air volume adjusting lever 34 can be rotated around the axis.

  The left and right first injection tubes 13 are arranged on the lower side along the longitudinal direction of the through-cylinder 30, that is, the conveyance direction, and further, the second injection can be bent to the first injection tube 13 via a bellows tube 40. Connect the tube 14.

  The cylindrical body 42 connecting the bellows tube 40 is provided with a lateral support shaft 47, and the second injection tube 14 is connected via the support shaft 47, and in addition to the movement to the storage posture by folding forward, It can be turned up and down by turning around the support shaft 47 and can be switched between a vertical storage posture and a horizontal working posture. The right second jet tubes 14, 14 can be switched to a vertical posture (non-working posture) or a horizontal posture (working posture).

  In the second jet tube 14, nozzle holes 50, 50... Having a predetermined diameter are formed at predetermined intervals. In these nozzle holes 50, 50..., Inclined collision plates 51, 51. In addition, the left and right first nozzles 13 positioned below the feeding device 11 are respectively formed with nozzle holes 32 at the lower portions thereof, and the first collision plates 33 are formed in the nozzle ports 32 in the same manner as the second collision plates 51 and 51. Is provided.

  The purpose of providing the first impingement plate 33 provided in the first jet tube 13 is to disperse the powder and particulate matter toward the abdomen of the fuselage, and the configuration thereof is as follows. A support plate 35 provided with a hinge 35 a is fixed to the lower surface of the first jet tube 13. The hinge 35a is configured to fix the support plate 35 with an axial axis in the front-rear direction, and further, a rod connector 35b is connected to a portion extending from the nozzle 32 to the outside. Further, a rod 36 is connected to the rod connector 35b. A bent portion 36a is formed in the middle portion of the rod 36. When the grip portion 36b at the tip (front end in the illustrated example) is rotated, the first collision plate 33 is rotated around the hinge 35a, and the effective height of the collision plate 33 is increased. The height H can be adjusted to be high or low. In addition, a cylindrical holder 37 provided by appropriately projecting from the machine body side is provided at a position closer to the grip portion 36b than the middle bent portion 36a of the rod 36, and the rod 36 is inserted and held in the holder 37, and The inner periphery of the rod 36 is provided on the friction surface, and the rod 36 is configured to maintain its position even if the hand is released from the grip portion 36b of the rod 36. With this configuration, the collision height H of the first collision plate 33 at the nozzle 32 of the first injection tube 13 can be arbitrarily changed and adjusted, so that the scattering distance varies depending on properties such as the specific gravity and particle size of the granular particles. However, the discharge state from the nozzle 32 can be made good, and the spraying in the lower part of the machine body can be carried out well.

  In particular, operability can be improved by connecting a remote control means to the first collision plate 33 such as a rod 36 or a wire. In addition, when the grip part 36b of the rod 36 is configured to a position close to the seat as in the present embodiment, the adjustment work can be performed while continuing the work without stopping and adjusting the machine body one by one. Convenient.

  In the present embodiment, the collision height H of the first collision plate 33 at the nozzle 32 of the first nozzle 13 can be arbitrarily changed. However, the second collision plate 51 of the nozzle 50 of the second nozzle 14 is described. Also, the collision height may be arbitrarily changed. Even when the collision height of the second collision plate 51 can be changed, the discharge situation due to the collision can be adjusted.

  Next, the control unit 15 of the powder and grain dusting device 1 having the above configuration will be described. The control unit 15 includes a fertilizer controller 15A, a motor controller 15B, and a main machine controller 15C connected to each other (FIG. 7). Among them, the fertilizer controller 15A includes data necessary for fertilization and herbicide application, for example, the feeding roll. While inputting the motor rotation pulse of the drive motor 24, the selection information by the left and right boom spreading levers 48L and 48R, the drive information of the blower fan 12a, the remaining amount sensors 54 and 54 provided in the tank 10, etc., the motor controller 15B A motor rotation output pulse signal, a motor rotation direction switching signal, etc. are output to (Fig. 7).

The machine controller 15C is configured to transmit the vehicle speed data from the means for detecting the vehicle speed to the fertilizer controller 15A.
In addition, the fertilizer controller 15 </ b> A inputs information on switches disposed on the operation panel 55. A variable switch 57, a fertilizer setting switch 58, increase / decrease switches 59U and 59D, and a cumulative reset switch 60 are provided in the vicinity of the liquid crystal display unit 56 in the operation panel 55 of FIG. 7, and these operation switch signals are transmitted to the fertilizer controller. This is a configuration input to 15A. The display content of the liquid crystal display unit 56 can display a fertilizer application set value, a specific gravity value, a memory value, and a cumulative value, and is output so as to be sequentially switched and displayed by turning on the display changeover switch 61.

  When a key switch (not shown) is turned on, the automatic mode is entered. In this automatic mode, a motor rotation output pulse (feeding roll drive motor) is sent to the motor controller 15B that drives the feeding roll of the feeding device 11 in accordance with the fertilizer application set value and the vehicle speed so that the fertilizing amount per unit area becomes constant. (Rotation signal) is output.

  Before starting work, turn on the fertilizer setting switch 58 to display the currently set fertilizer amount (counter-attack fertilizer amount (kg)) and check whether the fertilizer amount is suitable for the work to be done. When the change is made in units of 1 kg by the switch 59U or the decrease switch 59D and the fertilizer setting switch 58 is turned on again for a predetermined time (for example, 2 seconds or more), the value A (kg) is stored (FIG. 9, step 101).

  Next, specific gravity is set (step 102). When the display changeover switch 61 is turned on and “specific gravity” is selected, the current set value is displayed. It is confirmed whether or not the specific gravity value is suitable for the work to be performed. If the specific gravity value is different, it is changed in increments of 0.01 by the increase switch 59U or decrease switch 59D. When turned on, the value D (g / cm 3) is stored.

  As described above, which of the feeding rolls of the feeding device 11 is used, that is, the type of the feeding roll, is determined depending on whether the fertilizing amount A falls within a preset range of large, medium, or small. The In the case of the present embodiment, when the fertilization amount is determined (steps 102 to 105), the rotation direction of the feeding roll drive motor 24 is determined. That is, when the fertilizer application amount A corresponds to a large application amount of, for example, a1 (for example, a1 = 25 kg) or more, the feed roll drive motor 24 is rotated forward so that the first feed roll 20a and the second feed roll 20b operate. A signal is output (steps 106 and 108).

  Similarly, when the fertilizer application amount A corresponds to a medium application amount of a2 ≦ A ≦ a1 (for example, a2 = 5 kg), a reverse rotation signal is output to the feeding roll drive motor 24 so that the second roll 20b is operated (step) 104, 107).

  A reverse rotation signal is output to the feeding roll drive motor 24 so that the third roll 20d operates even when the fertilizer application amount A corresponds to a small application amount of A <a2 (steps 105 and 107). In addition, although the same motor reverse rotation signal is output as the middle spray amount, the feed spatter from the feeding device 11 is determined depending on whether the spatter is stored in the section A or the section B (step) 108, 109).

  As described above, the feed roll type 1, type 2 or type 3 is determined and changed to the driving state by changing and setting the combination of the feed rolls that are set so that the feed amount varies depending on the spread amount setting of the spread material. Is set.

  In this embodiment, the inside of the tank is divided into a section A and a section B, and the feed roll type is selected and set. In particular, the small section formed by the section B, the partition wall 17A and the outer inclined surface 10b of the tank 10 is used. Since the small-capacity tank portion 16A is arranged in the center of the front and rear of the tank 10 in the capacity tank portion 16A, it can be easily inserted from the upper open portion from the rear side or the front side. It can be done easily.

After the determination of the motor drive rotation direction is made as described above, the feed roll rotation speed is determined after the input of the vehicle speed signal and the determination of the set specific gravity (steps 110 to 113).
The feed roll rotation speed Rb calculated by the fertilizer controller 15A based on the vehicle speed S and the like as described above is output to the motor controller 15B, and the feed roll drive motor 25 is rotationally interlocked based on the calculated value.

Note that when the vehicle speed S reaches a specified value due to the start of airframe travel, a motor rotation output pulse (roll drive motor rotation signal) is output. When the vehicle speed S falls below the specified value, it is determined that the vehicle has stopped traveling and the motor rotation output pulse is stopped. Even during traveling, when the spray switch 69 is turned off or the fan switch 70 is “OFF”, the output of the motor rotation output pulse (feed roll drive motor rotation signal) is stopped. Further, when the vehicle speed becomes high and the calculated motor rotation speed value exceeds a preset upper limit value, a buzzer (not shown) is turned on intermittently with a long sound.

  Depending on the feeding roll rotation direction and the drive motor rotation speed set as described above, the powdered and granular material is fed out in a predetermined manner, and receives the blast from the blower 12a of the blower 12 to receive the first and second jet tubes 13 and 14. The blast from the blower 12 a is sent forward in the blower cylinder 13, branches left and right at the end thereof, and enters the left and right cylinders 30. Here, when the feed rolls 20a to 20c looking upward from the through-cylinder 30 set the rotation X from the upper part to the lower side through the front side of the machine body to the forward rotation, the action of feeding the blast into the through-cylinder 30 at most. Since the blast with a larger radius changes the flow velocity, it can be transported smoothly. In addition, the fed powdery granular material is carried in the first and second jet tubes 13 and 14 on the jet, but since the carrying direction is straight, the jet is unlikely to be turbulent and smoothly. Can be transported.

  As in the present embodiment, when the blow tube is provided from the rear to the front, and then the left and right cylinders are connected to each other and the blow pipes 13 and 14 are provided so as to extend in the guide direction of the blow by the through cylinders, Thus, it is only necessary to bypass the air flow, and it is possible to eliminate the curved conveyance of the granular material and to reduce the conveyance loss.

  FIG. 10 shows the details of the first jet tube 13 and the second jet tube 14. As described above, one end of the bellows tube 40 is inserted into the first jet tube 13, and the base of the second jet tube 14 is attached to the other end of the bellows tube 40. A base portion of the second injection tube 14 made of hard chloride resin is slightly fitted to the distal end cylindrical portion of the bellows tube 40 and fixed by a clamp 41. Reference numeral 43 denotes a reinforcing rod provided along the second jet tube 14, and a base portion thereof is a cylindrical body 45 provided integrally with an arm member 44 provided in an extended state from the lateral support shaft 47 for vertical rotation. The holding means is configured by being fitted to the distal end portion of the bellows tube 40. A holding cylinder 46 capable of inserting and holding the base of the reinforcing rod 43 is integrally provided in the cylinder 45. The reinforcing rod 43 is inserted through the holding cylinder 46 at the base, and the middle portion and the tip portion are held by the bracket 48. The bracket 48 is composed of a pair of metal fittings provided so as to be fitted on the second jet tube 14, and is configured to hold the reinforcing rod 43 on opposing extension holding portions 48 a formed on the upper part thereof.

  As described above, since the base portion of the reinforcing rod 43 is inserted and held in the predetermined long holding cylinder 46, the reinforcing rod 43 is compared with a configuration in which the side surface of the reinforcing rod 43 is held by screw fastening with a conventional bracket plate. Therefore, it is difficult to cause a deviation between the extended posture and the extended posture of the second jet tube 14, and cracking of the second jet tube 14 can be prevented. That is, in the conventional configuration, only a part of the side surface of the base portion of the reinforcing rod 43 is fixed. Therefore, the reinforcing rod 43 is difficult to restrain and lacks in stability, and easily shifts from the second jet tube 14. Although it is a cause of crack breakage, it can support stably by comprising like a present Example.

  A wire 75 is connected to the upper end of the bracket 48, and the wire 75 is connected to the left and right jet tube up / down levers 76. Based on the pivoting operation of the lever 76, the second jet tube 14 pivots upward about the lateral support shaft 47 and assumes a storage posture. The wire 75 is wound around a pulley 78 disposed on the upper side of the main frame 77 of the spraying device 1, and further wound around a pulley 79 on the lower side of the frame 77. Fastened to an interlocking member interlocking with 76. When configured as described above and the operation of raising and lowering the jet tube up / down lever 76, the wire 75 is pulled, and the second jet tube 14 can be pulled toward the machine body side to stand upright.

  Based on FIG. 11, the mounting configuration of the spraying device 1 will be described. A tank 10, a feeding device 11, a blower device 12, and a first injection tube 13 are attached to the main frame 77 of the spraying device 1. Reference numeral 78 denotes a moving frame provided with casters 79 and is provided integrally with the main frame 77. A connecting frame 79 is provided on either the main frame 77 or the moving frame 78. The front end of the connection frame 79 is configured to be freely mounted on a connection hitch 80 formed at the rear part of the traveling machine body. A winch 81 is set at the front part of the traveling machine body, and the wire 81w of the winch 81 is wound around the pulley 82a of the front column 82 standing on the front part of the machine body and the pulley 83a of the intermediate column 83 located at the rear part of the seat 7. Then, the end portion is connected to the auxiliary stay 84 fixed to the main frame 77. Therefore, when the wire is wound up by the pulley, the main frame 77 is pulled up to the mounting posture (FIG. 12) while rotating around the connection point with the connection hitch 80 together with the spraying device 1. When the spraying device 1 is adjusted to an appropriate posture and is close to a predetermined setting position at the rear of the traveling machine body, the spraying device 1 is set at an appropriate position while being aligned by an operator. If comprised in this way, since the spraying apparatus 1 can be pulled up by winch 81 operation, the spraying apparatus 1 can be mounted | worn easily and non-wearing.

  13 and 14 relate to improvements in the upper and lower wire of the jet tube and its interlocking configuration. Left and right jet tube up / down levers 85L and 85R are arranged on the left and right sides of the machine body, respectively. In the configuration in which the first and second jet tubes 13 and 14 are disposed within the front-rear width of the tank 10 and project in the extending direction of the roll drive shaft 21, the first and second jet tubes 13 and 14 are provided. 2 The other end of the wire 86 connected to the middle part of the jet tube 14 is wrapped around a pulley 88 provided on the upper part of the side surface of the main frame 87 of the spraying device 1, and a pulley 89 provided on the lower part of the side surface of the main frame 87. It is wound around the front and is engaged with bracket portions 85La and 85Ra integrated with the upper and lower levers 85L and 85R. The jet tube up / down levers 85L and 85R can be rotated around the axial center in the left-right direction, and when pulled up, the wire 86 can be pulled and the second jet tube 14 can be rotated up around the lateral support shaft 90.

  The pulleys 88 and 89 are both provided on a vertical plane including the second jet tube 14. Therefore, the pulleys 88 and 89 supporting the wire 86 are rationally arranged, and the operation load of the jet tube upper and lower levers 85L and 85R can be minimized. The second injection tube 14 is connected to the first injection tube / bellows tube 40 of the spraying device 1 in a normal posture.

  In addition, one of the upper and lower levers (right side in the figure) 85R of the upper and lower levers is arranged in the vicinity of the clutch lever 90 that engages and disengages the clutch means 28 provided in each of the left and right feeding devices 11. ing. If comprised in this way, there exists an effect which becomes the arrangement | positioning structure which is easy to apply a big operation load by arrange | positioning the jet pipe upper / lower lever 85 with a large operation load below with respect to the clutch lever 90.

  Since the second injection tube 14 is connected to the first injection tube 13 via the bellows tube 40, the longitudinal support shaft 91 can be configured to turn the machine body in the front-rear direction. In the embodiment shown in FIG. 14, a tube receiver 93 is provided in front of the step 92 for raising and lowering on both sides of the machine body. If comprised in this way, since the mode of the jet tube 14 from the seat 7 can be confirmed, the storing operation to the jet tube receiver 93 becomes easy.
