The fertilizer applicator B is arranged along the tool bar 42 supported via the support frame 41 above the tilling frame 31, the hitch 32, and the like, and is configured so that the mounting position can be adjusted in the horizontal direction.

  Here, the construction of the vertical fertilizer is such that a tilling rotary 6 and a straw molding machine 7 for cultivating this tilled soil are attached to the rear of the tractor vehicle body 1, and the upper part of the front tilling rotary 6 is located at the left and right central positions. Is provided with a grain feeding hopper 8 for feeding the granular material mainly for applying the medicine, and for feeding the powdery material mainly for applying fertilizer to the left and right side positions in the upper part of the rear molder 7. Powder feeding hoppers 9 and 9 are provided. As the vehicle body 1 advances, the soil surface is cultivated by the cultivating rotary 6, and the cultivated soil surface is cultivated by the cocoon molding machine 7 to form the cocoon. A granular medicine fed from the grain feeding hopper 8 and a powdered fertilizer fed from the powder feeding hopper 9 are applied to the koji while stirring with the soil. In the application of such powders and granules, the grain feeding hopper 8 is mounted on the center above the tilling rotary 6 at the front, and the powder feeding hopper 9 is mounted on both the left and right sides above the rear straw molding machine 7. Then, the feeding down application of the powdery material (powdered fertilizer) and the granular material (granular medicine) is performed vertically downward.

  In the working machine form that is applied to the isolated soil surface while mixing the granular material (granular drug) and powdered material (powder fertilizer), if these drugs and fertilizer are stored separately, the feeding hopper The number of installations increases at the top of the tillage rotary, and the space occupied by these increases, and the supply work and maintenance of fertilizer and the like are likely to be complicated, but as described above, the tillage rotary 6 and the rear of the tractor vehicle body 1 A hull former 7 that receives the tilled soil and wrinkles is mounted, and a grain feeding hopper 8 that feeds out the granular material is provided in the upper left and right center positions of the front rotary rotary 6, and the rear hull former In the upper part of 7, the above-mentioned problem is solved by adopting a configuration of a vertical fertilizer device provided with a powder feeding hopper 9 that feeds a powdery material at both left and right positions. That is, the soil surface is cultivated by the tillage rotary 6 as the vehicle body 1 advances, and the cultivated soil surface is cultivated and culled by the culvert molding machine 7, and the granular material fed from the grain feeding hopper 8 is formed on the ridge surface. The powdered material fed from the powder feeding hopper 9 is applied, but since the hoppers 8 and 9 are arranged to be shifted from front to back and from side to side, the capacity of the hoppers 7 and 8 is set large, This makes it easy to perform operations such as supplying granular materials to the hopper 8. Therefore, according to the above configuration, since the grain feeding hopper 8 and the powder feeding hopper 9 are arranged in a form shifted in the front-rear and left-right directions, the capacities of these hoppers 8 and 9 can be effectively increased. It is possible to easily maintain the grain feeding hopper 8 at the upper portion of the tilling rotary 6, particularly at the central portion.

  Next, in the above-described embodiment, the grain supply ports 45a of the hose 45 that flows down the granular material (granular medication) fed from the grain feeding hopper 8 are diffused and spread on the field with the spreading rod 46, and the powder feeding hopper The powder supply port 47a of the hose 47 that flows down and guides the powdery matter (powdered fertilizer) fed from 9 is locally sprayed on the farm field with a cylindrical basket 48.

  Each of the feeding hoppers 8, 9, 9 has a substantially square shape in plan view and has a lid 50 that can be opened and closed. At the bottoms of the feeding hoppers 8, 9, 9 are provided feeding devices 51, 51, 51 for driving the feeding rolls with a motor to feed the powdered or granular materials of the hoppers 8, 9, 9. Each feeding device 51 is provided with feeding outlets 52, 53, 53 at three locations, and the hoses 45, 47, 47 are connected to the feeding devices 51, respectively, and the granular material G (granular medication) is diffused by these hoses 45, 47, 47. The powder 46 (powder fertilizer) is spread on the field through the cylindrical baskets 48, 48.

  The diffusion rod 46 includes a receiving tube body 46a into which the lower end of the hose 45 is inserted, a wing portion 46b that guides and diffuses the particulate matter discharged from the receiving tube body 46a, and an upper scattering prevention plate 46c. Thus, it is configured to diffuse and fall to the left and right while sliding on the wing part 46b. On the other hand, the cylindrical rod 48 is configured to receive a tip of each of the hoses 47 and 47 connected to the left and right feeding hoppers 9 and 9 provided to a pair.

  The spreading rod 46 and the pair of cylindrical rods 48, 48 are horizontally supported on the front side of the tilling rotary 6 between the stays 49a, 49a, ... that extend forward and downward from the frame of the tilling rotary 6. It is supported by the rod 49b. The diffusion rod 46 is located in front of the support rod 49b, and the cylindrical rods 48, 48 are located in the rear.

  The granular material G (granular medicine) from the diffusion rod 46 diffuses and drops to the left and right in the front of the machine body and falls into the sprayed state on both the inside and outside of the left and right discs 25 and 25 facing the tilling rotary 6. The powder body P (powder fertilizer) from 48 falls substantially downward and is spread within the interval between the left and right discs 25, 25 facing each other, and the adjustment in the left-right direction is performed by the support rod 49b. On the other hand, the locking bolt nut 55 of the brackets 46a, 48a, 48a through which the diffusion rod 46 and the cylindrical rods 48, 48 are penetrated. The receiving cylinder 46a of the diffusion rod 46 and the upper portions of the cylindrical rods 48, 48 are formed in an expanded shape so that the lower end of the hose can be easily inserted.

  A spreading rod assembly comprising a diffusion rod 46 and a pair of cylindrical rods 48, 48 is provided corresponding to the number of rods to be formed later. In the example shown in the figure, the center and the left and right are made up of three sets of spraying sets.

  As described above, the feeding device 51 of the feeding hopper 8, the hose 45 and the diffusion rod 46 constitute the diffusing means W for diffusing and spreading, and the feeding devices 51 and 51 of the feeding hoppers 9 and 9, the hoses 47 and 47, and the cylinder The feeding means H that performs standard local spraying is constituted by the state rods 48, 48.

The operation of the above example will be described.
The granular material (granular medicine) fed out from the feeding hopper 8 is diffused and distributed to the front surface of the tilling rotary 6 through the diffusing means K to a predetermined width on the left and right. In addition, the powdery material (powdered fertilizer) fed from the feeding hoppers 9 and 9 is locally sprayed immediately after the granular medication via the feeding means H. The soil surface cultivated by the cultivating rotary 6 is erected by the culverter 7, and the opposing disk is cultivated by the cultivating action by the cultivating rotary 6, that is, by the cultivating action of the cultivating claws 23, 23. Between 25 and 25, a part of the granular material (granular medicine) spread | diffused from the spreading | diffusion means K and all the powdery fertilizer spread | distributed locally from the delivery means H are stirred. Further, outside the opposing disks 25, 25, the granular material (granular medicine) sprayed from the diffusion means K is stirred together with the tilling action of the tilling claws 23, 23. After that, a predetermined strip (three strips in the illustrated example) of ridges R is formed by the subsequent ridge forming device 7.

  The powdery material (powder fertilizer) from the feeding means H is stirred between the opposing discs 51 and 51 in the basket R to be molded, and distributed between the disks 51 and 51 in the cross section of the basket. Further, since the powder and granular material fed out by the diffusing means K is agitated on the inner and outer sides of the disks 51, 51, it is distributed over the entire cross section of the bowl R raised by the bowl molding machine 7.

  Therefore, when it is more effective to distribute the entire area of the cross-section of the eyelid R like a specific medicine, the desired effect can be obtained by using the diffusion means K. In addition, in a specific fertilizer, by distributing it between the disks 25 and 25 by the feeding means H, it is not necessary to perform wasteful fertilization of the heel R particularly on the skirt portion, and low-cost work can be realized.

  In the said Example, although the granular material (granular medicine) was made into object by the spreading | diffusion means K, a powdery thing may be sufficient and not only a chemical | medical agent but fertilizer may be sufficient. This is effective when it is necessary to distribute the entire surface of the ridge.

  By arranging the diffusion rod 46 constituting the diffusion means K in the front position and the cylindrical rod 48 constituting the feeding means H in the rear position, the granular material and the powdery material that are both scattered in the forward and backward directions can be obtained. It is difficult to interfere with each other, and it can be evenly sprayed without agitating and uneven distribution in the basket. In addition, in this embodiment, since the discharge outlet of the diffusion rod 46 is set below the discharge outlet of the cylindrical rod 48, the above interference is less likely to occur.

There are also the following usage patterns.
If the distribution between the pair of discs 25, 25 facing each other in the forming basket is dense and the distribution other than this is desired to be thin in the spraying of the same granular material, the same granular material is applied to the feeding hoppers 8, 9, 9. And the same granular material is sprayed from both the feeding means H and the diffusing means K. If comprised in this way, the same fertilizer and the same chemical | medical agent can be sprayed by varying the distribution condition of a cocoon cross section, and the fertilization thru | or the chemical | medical agent situation suitable for the growth of a crop can be obtained.

In addition, by replacing the diffusion rod 46 of the diffusing means K with the cylindrical rod 48, the particulate matter of the feeding hopper 8 can be dispersed in the opposing disks 25, 25.
In the above-described embodiment, the so-called 3 畝 specification has been described. However, in addition to the 2 畝 specification, it can be similarly applied to 4 畝 or more, and the diffusion rod 46 and the pair of cylindrical rods 48, 48 along the support rod 49b. It is possible to adjust the proper arrangement by moving the spreader group consisting of
