  A pair of left and right molded plates 33, 33 (molded bodies) are supported and fixed to the lower end of the support column 27 and the lower ends of the left and right support rods 32, respectively. The left and right molded plates 33 are configured to be removable separately, and are formed so as to incline so as to be separated from each other toward the rear and to protrude rearward toward the upper side. Since a pair of left and right molded plates 33 and 33 are provided on the support column 27 and the left and right support rods 32 and 32, respectively, a total of six molded plates 33 are supported behind the rotary 6 via the tool bar 29. Thus, the upright 7 is constituted by these six molded plates 33.

  The erecting unit 7 forms a eaves forming portion 34 by two adjacent forming plates 33 and 33 so as to approach each other toward the rear. Specifically, the left molding plate 34L is configured by the right molding plate 33 supported by the left support rod 32 and the left molding plate 33 supported by the support column 27, and the left side supported by the right support rod 32. The starboard forming portion 34R is formed by the forming plate 33 and the right forming plate 33 supported by the support column 17, and two vertical hooks are simultaneously formed in the vertical stand 7 (see FIG. 3).

  The pair of forming plates 33, 33 constituting the ridge forming portion 34 press the left and right side portions of the tilled soil piled up by the rotary 6, and form slopes inclined in the left and right direction so as to approach each other. A band-like ridge is formed along the locus of the spray port 4a drawn therewith. By the way, the outermost left and right molding plates 33, 33 are for molding a slope on one side of the kite located on the outer side of the two kites molded by the erecting device 7.

  The ground ring 8 is provided on each of the left and right sides of the rotary 6 so as to overlap with the rotary 6 in side view. A chain case 36 extending downward is supported at the front end of each of the left and right support brackets 18 so as to be swingable back and forth. The grounding ring 8 is supported at the lower end of each of the left and right chain cases 36 so as to be able to rotate back and forth, and the outer end of the roller shaft 22 is inserted and supported at the upper end so as to be rotatable back and forth. Thus, when the grounding wheel 8 is rotated, power is transmitted to the roller shaft 22 via the chain 37 in the chain case 36, and the roller of the fertilizer supply device 3 is rotationally driven.

  At the rear end portion of the support bracket 18, an upper end portion of a support rod 38 extending obliquely downward toward the front is supported so as to be slidable in the axial direction. The middle portion of the chain case 36 is supported by the lower end portion of the support rod 38 so as to be able to rotate back and forth, and the chain case 36 is suspended in a state of facing obliquely downward toward the rear. A spring 39 is provided on the outer periphery of the support rod 38 to urge the chain case 36 in the downward swinging direction.

  As a result, the grounding wheel 8 is elastically biased to the lower side (farm field side) during work on the field by the walking fertilizer application machine, and is stably grounded to the field scene. The grounding wheel 8 rotates back and forth at a speed proportional to the traveling speed. Then, the roller is rotationally driven at a speed corresponding to the rotational speed of the grounding wheel 8. For this reason, an amount of fertilizer corresponding to the traveling speed is sprayed on the field through the spray port 4a.

  The handle 9 is attached and fixed to a handle frame 41 having a front end portion (base end portion, lower end portion) protruding obliquely rearward and upward from a center portion in the front-rear direction of the traveling machine body 1. The handle 9 is formed in a square shape in which two rod-like members in a plan view are widened so as to be spaced apart from each other in a plan view, and is extended obliquely upward toward the rear in a side view.

  The left and right rear end portions of the handle 9 are bent downward with respect to the front end portion and the midway portion, and a grip 42 is provided at this portion. An on / off lever 43 is installed in front of the right grip 42 of the handle 9 to turn on / off power from the engine 12 to the rotary 6 by a forward / backward swing operation. Middle portions of the left and right chain cases 36 are connected to the base end portion of the on / off lever 43 via wires 44.

  The operator grips the left and right grips 42 of the handle 9 to perform a steering operation, and swings the handle 9 upward to lift the rear portion of the traveling machine body 1 to raise the grounding wheel 8, the rotary 6 and the stand. It is possible to move the container 7 away from the farm scene, temporarily stop the work, and perform a turning operation or the like.

  In addition, as the power is turned off to the rotary 6 by the on / off lever 43, the middle portion and the lower end of the chain case 36 are lifted by the wire 44, and the grounding wheel 8 is separated from the field scene, while the on / off lever As the power is turned on to the rotary 6 by 43, the lifting of the chain case 36 by the wire 44 is released, and the grounding wheel 8 contacts the field scene by the elastic force of the spring 39 or the like. Then, the driving of the fertilizer supply device 3 is turned on / off by the grounding / ungrounding of the grounding wheel 8 to the field. Since the turning on / off of the rotary 6 is linked to the turning on / off of the fertilizer supply device 3 as described above, the convenience is high.

  The walking-type fertilizer application machine configured as described above spreads fertilizer to the field through four spray ports 4a as it travels forward, and plows the soil in the field where the fertilizer has been sprinkled with the rotary 6 to remove the fertilizer and the tilled soil. Let it stir. The rotary 6 is configured to pile up tillage on the trajectory side of the spout 4a drawn as it travels, and the left and right sides of this piled tillage correspond to the straw forming part corresponding to the vertical unit 7. The ridges are formed by pressing with the forming plate 33 of 34 to form a slope. Since this walking type fertilizer application machine has two ridge forming sections 34, two ridges on the left and right as shown in FIG. 3 are formed simultaneously. In addition, on the outer side of these two ridges, an inclination of one side portion of the ridge is formed by the two molding plates 33 and 33 arranged on the outermost side.

  From the above actions, each cocoon is composed of cultivated soil in which a fertilizer is appropriately mixed. By planting and cultivating crops in this paddy, it becomes possible to apply fertilizer only to the vicinity of the crop stock, so the amount of fertilizer used in fertilization work can be reduced, and fertilizer can be used as cultivated soil. Since it is used in a mixed state, the fertilizer failure of the crop is suppressed as compared with the case where the fertilizer is directly applied to the stock of the crop with a nozzle or the like. In addition, it is possible to save labor by molding two coffins fertilized with fertilizer at the same time. In addition, since it is a walking type fertilizer application machine, the headland necessary for turning should be narrowed. Can do.

  Further, by providing the crawler 13 and the handle 9, a fertilizer working machine capable of forming a plurality of ridges while performing fertilization work can be used alone without being connected to a puller such as a tractor. For this reason, it becomes possible to form the whole compactly, and to achieve labor saving and efficiency improvement of work even in a narrow field.

  Further, the support structure of the tool bar 29 with respect to the support column 27 and the support structure of the left and right support rods 32 with respect to the tool bar 29 are configured so that the vertical position of the elevator 7 can be adjusted up and down and left and right and the width of the rod to be formed can be changed. This makes it possible to cope with various field conditions, so that the versatility of the fertilizer application machine is improved.

  In addition, since the traveling straightness is improved by the crawler 13, more efficient work can be performed.

  In addition, even when the traveling speed changes due to slip or the like, the amount of fertilizer supplied to the spout 4a changes according to the traveling speed due to the action of the grounding wheel 8, so that the fertilizer in the field due to the change in traveling speed There is an effect that spray spots can be minimized.

  In addition, by associating the raising / lowering of the grounding wheel 8 with the swinging operation of the on / off lever 43 for turning on / off the rotary 6, the grounding wheel 8 is separated from the field scene with the driving stop operation of the rotary 6. Since it becomes possible to automatically stop fertilizer supply to the mouth 4a, there is an effect that operability and convenience are improved. In addition, by providing the grounding wheel 8 on the side of the rotary 9, it is easy to configure the grounding wheel 8 to be separated from the field scene as the rotary 6 is separated from the field scene. .

  FIG. 4 is a main part rear view showing a state of fertilization work and cocoon forming work by the walking-type fertilizer application machine with the two outermost forming plates 33, 33 removed. By removing the two outermost formation plates among the six formation plates 33, the required propulsive force is reduced, so that the engine 12 having a lower output can be used.
