Mounted on a management machine having a plurality of feeding devices on the left and right with respect to the traveling direction, comprising a feeding unit, a fertilizer hopper attached to the upper part of the feeding unit, and a feeding pipe attached to the lower part of the feeding unit In the traveling type fertilizer applicator, the fertilizer hopper is configured to be long in the left-right direction in order to increase the capacity of the fertilizer hopper of the feeding device.
Japanese Patent Laid-Open No. 4-4808

  However, when the fertilizer hopper is configured to be long in the left-right direction and the capacity is increased, the distance between the left and right fertilizer hoppers is reduced without widening the left and right arrangement intervals of the feeding device. May interfere with the application of the fertilizer machine. Further, considering the mounting of the fertilizer applicator, the degree of freedom of arrangement of the steering wheel, transmission, etc. of the management machine is also limited. On the other hand, even if the fertilizer hopper is configured to be long in the left-right direction to increase the capacity, it may be possible to mount the fertilizer on the management machine by widening the left-right arrangement interval of the feeding device. However, in this case, since the feeding unit is separated from the management machine, it is necessary to lengthen the feeding pipe attached to the lower part of the feeding unit in order to fertilize the root of the crop. Then, there is a high possibility that the fertilizer flow becomes worse due to clogging of the fertilizer in the feeding pipe.

  In view of the above situation, the present invention provides a fertilizer applicator that can increase the capacity of a fertilizer hopper without hindering the feeding performance of the fertilizer and can be mounted without selecting the type of the management machine.

  Further, a hitch 13 protrudes rearward from the rear portion of the mission case 7, and the fertilizer applicator 3 is attached to the hitch 13. In addition, a toolbar 70 is provided in the rear part of the hitch 13, and the feeding devices 30 and 30 and the ground ring 60 are attached to the toolbar 70 to constitute the fertilizer applicator 3. Further, the fertilizer applicator 3 is configured such that fertilization work is performed by driving the feeding units 31 and 31 by the rotation of the ground ring 60. In the present embodiment, two feeding devices 30 are provided, but the number of feeding devices 30 is not limited to two.

  Next, the feeding devices 30 and 30 of the fertilizer applicator 3 will be described with reference to FIGS. The feeding devices 30 and 30 are attached to the rear surfaces of the locking tools 71 and 71 that are detachably attached to the left and right of the toolbar 70. Since the feeding devices 30 and 30 are configured symmetrically, only one feeding device 30 will be described below, and description of the other feeding device 30 will be omitted.

  The feeding device 30 includes a feeding part 31, a fertilizer hopper 34 attached to the upper part of the feeding part 31, and a feeding pipe 35 attached to the lower part of the feeding part 31. The feeding part 31 includes a front feeding part 32 and a rear feeding part 33, and the front feeding part 32 and the rear feeding part 33 are arranged in the front-rear direction at the lower part of the fertilizer hopper 34. The part 32 and the rear feeding part 33 are integrally fixed by a mounting tool 72 and attached to the rear surface of the locking tool 71 via the mounting tool 72. The fertilizer hopper 34 is configured to be able to supply the fertilizer by opening the upper lid 34a, and is configured to be longer in the front-rear direction than in the left-right direction. In this embodiment, the fertilizer hopper 34 is shared by the front feeding unit 32 and the rear feeding unit 33 in consideration of workability such as fertilizer charging, but separately for each of the front feeding unit 32 and the rear feeding unit 33. It is good also as a structure which provides this fertilizer hopper. Moreover, although mentioned later for details, the feeding apparatus 30 is comprised so that switching of the 1 row fertilization by either one of the front delivery part 32 and the back delivery part 33 or the two-way fertilization by both can be performed.

  The feed pipe 35 is a flexible flexible deformable soft member to which the fertilizer is difficult to adhere, and guides the fertilizer fed from the feed portion 31 to the root of the crop, and discharges the fertilizer from the discharge port. It also serves as an interval adjusting means for adjusting the discharge position of the discharge port. The feeding pipe 35 includes a front feeding pipe 36 and a rear feeding pipe 37, and is attached to the lower portions of the front feeding portion 32 and the rear feeding portion 33 in the front-rear direction via a front funnel 38 and a rear funnel 39, respectively. The front feed pipe 36 guides the fertilizer fed from the front feed section 32 to the root of the crop, discharges the fertilizer from the front discharge port 36a, and the rear feed pipe 37 feeds the fertilizer fed from the rear feed section 33 to the crop. The fertilizer is discharged from the rear discharge port 37a. Further, the front feeding pipe 36 and the rear feeding pipe 37 are respectively inserted in the front feeding pipe mounting tool 40 and the rear feeding pipe mounting 41 at the tip of the mounting ring extending obliquely downward from the locking tool 71. It is supported. The front feeding pipe fitting 40 and the rear feeding pipe fitting 41 are, for example, metal rod-like members, and the tip is formed in a ring shape so that the feeding pipe can be inserted. In the present embodiment, the feeding pipe 35 serves as both a guide body and a streak adjusting unit, but the guide body and the streak adjusting unit may be configured separately. For example, a funnel having a discharge port inclined in one direction in a plan view is rotatably attached to the lower portion of the feeding unit 31 to guide the fertilizer fed from the feeding unit 31 to the root of the crop, and the funnel By rotating, the discharge position of the discharge port can be adjusted to adjust the interval. Further, by providing a movable portion at the discharge port of the funnel, the discharge position of the discharge port can be easily adjusted.

  Moreover, as shown in FIG. 3, the front feeding part 32 and the rear feeding part 33 are each provided with a front feeding roll 32a such as a groove roll type and a rear feeding roll 33a. A plurality of front feed roll grooves 32b, 32b..., And rear feed roll grooves 33b, 33b... Are formed on the surfaces of the front feed roll 32a and the rear feed roll 33a. Only the fertilizer that has entered the groove is drawn out. The front feeding roll 32a and the rear feeding roll 33a are fixed to the front feeding roll shaft 32c and the rear feeding roll shaft 33c, respectively, so as to rotate integrally with the front feeding roll shaft 32c and the rear feeding roll shaft 33c. It is configured. The front feed roll shaft 32c is configured to have a length equal to or longer than the width in the left-right direction of the management machine 1, and the left and right front feed rolls 32a and 32a are fixed to the same shaft. As described above, the feeding devices 30 and 30 that are detachably attached to the left and right of the tool bar 70 via the locking tools 71 and 71 are within the range of the left and right width of the front feeding roll shaft 32c. -The left and right positions of 30 are changed. Although details will be described later, a front feed roll shaft sprocket 32g for driving the feed portions 31 and 31 by rotation of the ground ring 60 is detachably provided at the center of the front feed roll shaft 32c. .

  A front shutter 32d and a rear shutter 33d serving as switching means for switching the number of fertilizers are attached between the fertilizer hopper 34, the front feeding portion 32, and the rear feeding portion 33, respectively. The front shutter 32d is attached to the front part of the fertilizer hopper 34, and the rear shutter 33d is attached to the rear part of the fertilizer hopper 34 so that it can be inserted and removed in the front-rear direction. That is, in the state where the front shutter 32d and the rear shutter 33d are inserted to the maximum extent, no fertilizer is supplied from the fertilizer hopper 34 to the front feeding unit 32 and the rear feeding unit 33, and the front shutter 32d and the rear shutter 33d are pulled out. Thus, the fertilizer hopper 34 communicates with the front feeding unit 32 and the rear feeding unit 33, and the fertilizer is supplied from the fertilizer hopper 34 to the front feeding unit 32 and the rear feeding unit 33. In this embodiment, the shutters are the front shutter 32d and the rear shutter 33d. However, the shutter may be one, and the number of shutters is not limited to this embodiment. Further, the switching means is not limited to the shutter system shown in the present embodiment. For example, by switching one feeding pipe 35 to the other feeding pipe 35, switching from two-way fertilization to single-row fertilization is possible. It is.

  Moreover, the front feeding part 32 and the rear feeding part 33 are each equipped with the front brush 32e and the rear brush 33e which are pig hair etc. inside, respectively. The front brush 32e is inserted into the front feeding portion 32 and the rear feeding portion 33 from the front surface of the case of the front feeding portion 32, and the rear brush 33e is inserted into the front feeding portion 32 and the rear feeding portion 33 from the rear surface of the case of the rear feeding portion 33, respectively. The tip of the brush is in contact with the rear feed roll 33a. As a result, excess fertilizer that does not fit in the front feeding roll grooves 32b, 32b,... And the rear feeding roll grooves 33b, 33b,... Is removed by the front brush 32e and the rear brush 33e as the roll rotates. Only the fertilizer that has entered the front feeding roll 32a and the rear feeding roll 33a is fed out and fertilized through the front funnel 38, the rear funnel 39, the front feeding pipe 36, and the rear feeding pipe 37.

  With such a configuration, two-way fertilization can be performed with one feeding device 30. Then, by opening and closing the front shutter 32d and the rear shutter 33d, the number of fertilization lines can be easily switched according to the number of lines of agricultural products. In addition, since the feeding pipe 35 also serves as a streak adjusting means, it is not necessary to separately provide a streak adjusting means, and the fertilizer fed from the feeding unit 31 is guided to the root of the crop, and the fertilizer is reliably applied to the base of the crop. it can.

  Further, as described above, in this embodiment, the feeding portions 31 and 31 are driven by the rotation of the ground ring 60 so that the fertilization work is performed. That is, the ground ring 60 is attached to the approximate center of the tool bar 70 via a locking tool, and the support frame 61 extends backward from the locking tool. The upper portion of the mounting plate 62 is pivotally supported at the rear portion of the support frame 61, and the lower end of the mounting plate 62 is a midway portion of the transmission case 63 that extends obliquely downward from the midway portion of the support frame 61. Is pivotally supported. A wheel shaft 64 is rotatably supported at the lower portion of the transmission case 63, and a wheel 65 is fitted and fixed to the wheel shaft 64. Further, a front feed roll shaft sprocket 32g is fixedly provided at an upper portion in the transmission case 63 and at a center portion of the front feed roll shaft 32c, and the sprocket fixed to the wheel shaft 64 and the front feed roll. A chain is wound around the shaft sprocket 32g. As a result, when the wheel 65 of the grounding wheel 60 is rotated with the progress of the management machine 1, the sprocket fixed to the wheel shaft 64 is rotated, and the chain in the transmission case 63, the forward feed roll shaft The pre-feed roll shaft 32c is driven through the sprocket 32g. On the other hand, a front gear 32f and a rear gear 33f constituting an interlocking mechanism are fixed to the front feeding roll shaft 32c and the rear feeding roll shaft 33c, respectively, so that the front gear 32f and the rear gear 33f are engaged. It is configured. That is, the driving force from the grounding wheel 60 is transmitted to the front feeding roll shaft 32c as described above, and is further transmitted to the rear feeding roll shaft 33c when the front gear 32f and the rear gear 33f are engaged. The

  Thus, when the management machine 1 moves forward, the wheel 65 of the grounding theory 60 rotates in conjunction with the wheel 65, the wheel shaft 64, the wheel shaft sprocket, the chain, the front feed roll shaft sprocket 32g, and the front feed roll shaft 32c. The fertilizer is fed out by the front feed roll 32a by rotating the front feed roll 32a counterclockwise. Then, through the front feed roll shaft 32c → the front gear 32f → the rear gear 33f → the rear feed roll shaft 33c, the rear feed roll 33a is rotated clockwise so that the fertilizer is fed by the rear feed roll 33a.

  With such a configuration, since it can be fed out in synchronization with the traveling speed, it is possible to uniformly fertilize. And since the feeding amount of all the feeding parts 31 and 31 can be equalized, it can fertilize uniformly. Moreover, since it is not necessary to provide a drive means in each of the front supply part 32 and the rear supply part 33, it is economical.

  The fertilizer hoppers 34 and 34 are configured to be long in the front-rear direction as described above, and the feeding devices 30 and 30 are arranged so that the interval can be changed in the left-right direction. As shown in FIG. 4, in the conventional fertilizer applicator 103, the fertilizer hoppers 134 and 134 are elongated in the left-right direction in order to increase the capacity of the fertilizer hoppers 134 and 134 of the feeding devices 130 and 130. However, when the fertilizer hoppers 134 and 134 are configured to be long in the left-right direction to increase the capacity, the distance between the left and right fertilizer hoppers 134 and 134 is narrowed. Therefore, depending on the type of the management machine 101, the handle 122 or the like may interfere. The fertilizer machine 103 may not be attached. Further, considering the mounting of the fertilizer applicator 103, the degree of freedom of arrangement of the handle 122, the transmission, and the like of the management machine 101 is also limited. Further, even when the fertilizer hoppers 134 and 134 are configured to be long in the left-right direction to increase the capacity, it is possible to improve the attachment to the management machine by widening the arrangement interval of the feeding devices. However, in this case, since the feeding parts 131 and 131 are separated from the management machine 101, the feeding pipes 135 and 135 attached to the lower part of the feeding parts 131 and 131 are used to fertilize the roots of the crops. Although it is necessary to lengthen the length, if the feeding pipes 135 and 135 are lengthened, there is a high possibility that the fertilizer flow is deteriorated due to clogging of the fertilizer in the feeding pipes 135 and 135. Therefore, as shown in FIGS. 1 and 2, the fertilizer hoppers 34 and 34 are configured to be long in the front-rear direction, and the feeding devices 30 and 30 are disposed so as to be able to change the spacing in the left-right direction.

  With such a configuration, the capacity of the fertilizer hoppers 34 and 34 can be increased, and the fertilizer hoppers 34 and 34 can be mounted regardless of the type of the management machine 1. And the freedom degree of arrangement | positioning of the handle | steering-wheel 22 of a management machine 1, a transmission, etc. is not restrict | limited. Moreover, since the feeding parts 31 and 31 do not leave one management machine, and it is not necessary to lengthen the front feeding pipe 36 and the rear feeding pipe 37, fertilizer feeding performance is not hindered.

  Moreover, the top fertilizer machine which concerns on this invention can also be comprised as follows. In addition, the structure of the feeding devices 30 and 30 is the same as that of the above-mentioned Example. That is, as shown in FIG. 5, the fertilizer applicator 203 has a pair of left and right feeding devices 30, 30 and grounding wheels 60, 60, and the grounding wheels 60, 60 are fitted into wheels 65, 65 in the grooves on the left and right sides of the basket. Is arranged so that the interval can be changed. The grounding rings 60 and 60 are attached to the left and right sides of the tool bar 70 via a locking tool, for example, with bolts or the like. For this reason, by changing the distance between the grounding wheels 60 and 60 according to the width of the saddle, the wheels 65 and 65 of the grounding wheels 60 and 60 can be positioned in the left and right grooves of the saddle.

  The front feed roll shaft 32c is configured to have a length equal to or greater than the width in the left-right direction of the management machine 201 as described above, and the left and right front feed rolls 32a and 32a are fixed on the same shaft. In addition, the driving force from the grounding wheels 60 and 60 is transmitted to the front feeding roll shaft 32c as described above, and further, the front gear 32f and the rear gear 33f are engaged with each other, whereby the rear feeding roll shaft 33c is engaged. Communicated. In other words, the feeding devices 30 and 30 are configured such that the feeding portions 31 and 31 are driven when one of the left and right grounding wheels 60 rotates. For this reason, when the fertilizer applicator 203 tilts to the left and right during traveling, even if one of the grounding wheels 60 rises, the feeding devices 30 and 30 do not stop as long as the other grounding wheel 60 is in contact with the field. The fertilization work will not be interrupted.

  Further, the management machine 201 has a pair of left and right traveling wheels 212 and 212. The traveling wheels 212 and 212 can be changed in distance so as to be positioned in the grooves on both the left and right sides of the kite. The axle 211 is arranged at a position higher than the heel height. In the present embodiment, the traveling wheels 212 and 212 are iron wheels, and are attached to the left and right sides of the axle 211 so that the left and right positions can be changed. For example, the traveling wheels 212 and 212 are inserted into the axle 211 via an attachment hole provided at the center of the traveling wheel 212 and fixed at an arbitrary position on the axle 211 by bolts or the like. For this reason, the traveling wheels 212 and 212 can be positioned in the left and right grooves of the kite by changing the distance between the traveling wheels 212 and 212 according to the kite width.

  In addition, the length of the advance roll axis | shaft 32c, the toolbar 70, and the axle shaft 211 needs to be more than the ridge width of the ridge which is the object of fertilization. Moreover, although these length is not limited, the longer one can respond to a wider wrinkle.

  With such a configuration, since it can be fed out in synchronization with the running speed, it can be uniformly fertilized, and the fertilizer applicator 203 can be attached to the management machine 201 so that it can run across the ridges. The heel is not stepped on by the traveling wheel 112 or the grounding wheel 60, and the lower part of the management machine 201 or the fertilizer applicator 203 does not touch the heel so as to crush the heel. For example, fertilization can be performed even when the ridge is high or wide, or when the crop is tall. In the present embodiment, two feeding devices 30 are provided, but the number of feeding devices 30 is not limited to two. For example, the feeding device 30 may be one.
