Description

  The present invention relates to an agricultural spraying apparatus for spraying, for example, a liquid or powdery pesticide for weeding or a liquid or powdered fertilizer for promoting germination and growth on a field.

  Conventionally, when spraying or spraying liquid or powdered pesticides or fertilizers on the field, pumps with heavy tanks filled with pesticides etc. hung on the shoulders of workers by bands or on the back While holding the nozzle attached to the tip of the hose that extended from the tank with one hand, the agrochemicals etc. were sprayed or sprayed on the planted part such as sputum to be sprayed (for example, Patent Document 1).

However, as described above, when a tank filled with a pesticide or fertilizer is shouldered, or when a medicine or fertilization work is carried out on the back, heavy labor is required regardless of age or sex, and a great deal of fatigue is required. Moreover, due to such fatigue, the work efficiency of drug application and fertilization decreases, and furthermore, accidentally spraying pesticides etc. unnecessarily on unnecessary plants or spraying pesticides on parts of the body. There was a risk of it. Such problems are not limited to so-called full-time farmers, but are also the same for relatively small side-job farmers and individuals who cultivate small fields such as kitchen gardens.
On the other hand, in order to eliminate the fatigue, there is also an apparatus for spraying herbicides or the like from a tank or the like loaded on a cargo bed through the nozzles by attaching a spray nozzle capable of turning along the vertical direction for each side of a light vehicle or the like. It has been proposed (see, for example, Patent Document 2).
However, since the above-mentioned spraying device requires at least a light vehicle, it is unsuitable for a relatively small part-time farmer or an individual who runs a kitchen garden due to high costs.

JP 2001-178346 A (pages 1-6, FIGS. 1-9) Japanese Utility Model Publication No. 05-17181 (pages 1-5, FIGS. 1-3)

  The present invention solves the problems described in the background art, can be used in relatively small fields and kitchen gardens at low cost, can reduce user fatigue, and is efficient, safe and reliable with agricultural chemicals and fertilizers. It is an object of the present invention to provide an agricultural spraying apparatus capable of performing a spraying operation.

Means for solving the problems and effects of the device

In the present invention, a tank filled with a liquid or powdery pesticide or fertilizer is placed in a hand-carrying carry bag (common name), and an operator walks along with the bag to manually apply or fertilize a target basket or the like. , It was conceived.
That is, the agricultural spraying device according to the present invention (Claim 1) includes a pair of wheels having a common rotating shaft, a storage unit attached above the pair of wheels and capable of storing a tank, and a lower part of the storage unit. A traction frame including a pair of arms extending from a side surface in an obliquely upward direction orthogonal to the rotation axis, and a handle disposed at a tip of the arm, and a direction attached between the pair of arms in the traction frame And a free wheel.

  According to this, a tank filled with pesticides is pulled by at least three wheels, a pair of wheels and a directional wheel attached between the arms of the traction frame, while the handle of the traction frame is pulled with one hand between the fields of the field. The nozzle connected to the tank is operated with the remaining one hand while conveying the uneven surface such as, and the like, and the planted surface to be sprayed can be sprayed efficiently and reliably. In addition, since the entire spraying device has a simple structure and relatively few components, it is possible to spray agricultural chemicals and the like with a little effort by a sense of carrying a so-called carry bag regardless of gender. Furthermore, since it can be produced at a low cost, it can be easily adopted for a relatively small part-time farmer or an individual kitchen garden.

In the present invention, not only liquid pesticides and fertilizers but also spraying of powdered pesticides and fertilizers is included in “spraying”.
The agricultural spraying device of the present invention mainly applies to fields and upland rice fields, but can also be applied to paddy fields with no water or paddy fields at relatively low times.
Furthermore, the storage part of the tank may be, for example, a box-shaped form, or a form in which a plurality of vertical guide frames are erected symmetrically, in addition to a frame shape with an open upper surface.
Also, the tank is connected to one end of a hose that has a nozzle at the tip for spraying filled agricultural chemicals and fertilizers onto the field, and on the side of the tank, a pump, motor, power supply A unit containing a built-in unit may be attached.
Further, the directional universal wheel may be one or two.

Further, in the present invention, the directional universal wheel is attached via a support leg that is slidable along a vertical direction or a diagonally downward direction between a pair of arms in the traction frame. Claim 2) is also included.
According to this, the supporting leg that supports the directional wheel can be slid with respect to each arm of the traction frame, and the distance (height) between the directional wheel and the pair of arms in the traction frame can be easily adjusted. . Therefore, the height of the handle of the traction frame can be changed according to the height and physique of the person performing the spraying work, and it is also possible to perform the spraying family work safely and comfortably while balancing with the heavy tank It becomes.

Furthermore, the present invention includes an agricultural spraying device (Claim 3) in which the bearing portion of the directional universal ring is tiltable with respect to a surface (vertical surface) including the axial direction of the support leg. .
According to this, when the support leg is slid with respect to the arm of the traction frame and the height of the traction frame is adjusted, the mounting angle of the bearing portion of the directional ring with respect to the vertical direction can be changed. Smooth rolling can be ensured at all times.
In the present invention, a pair of left and right inclined wheels inclined symmetrically so that the grounding sides are separated from each other are attached to positions in the width direction across the directional universal wheel. ) Is also included.
According to this, for example, when the present spraying device is moved in a recessed passage between a pair of ridges, the directional universal wheel is guided to a local recessed portion of the passage, and suddenly moves toward one of the ridges. When approaching by turning, the same inclined wheel on the same side hits the road surface of the passage, so that it is possible to prevent bending in an unintended direction. Therefore, even on an uneven road surface, the present spraying device can be easily moved along the ridges and fields on both sides.

Furthermore, in the present invention, an operation lever that can be rotated in the horizontal direction is disposed near the handle of the traction frame, and the other end of the wire that is coupled to the lever at one end contacts the wheel on the circumferential surface. Also included is an agricultural spray device (Claim 5) which is coupled to a link piece fixed to a rotating rod fitted with a detachable brake piece.
According to this, while holding the handle of the traction frame with one hand, the operation lever is pulled toward the operator with the finger of one hand, so that the wire coupled to the lever and the other end of the wire are coupled. The rotating rod is rotated through the link piece, and a pair of brake pieces fixed to both ends of the rotating rod are individually brought into contact with the peripheral surfaces of the pair of wheels, so that the pair of wheels can be quickly and reliably attached. Can lock. For example, in an uneven road between ridges, when the balance is about to be lost during transportation, the operation lever can be immediately pulled to bring it to a stopped state so that the balance can be easily restored. Therefore, it is possible to ensure the safety of workers and to reliably prevent inadvertent spraying or dissipation of agricultural chemicals and fertilizers.

In addition, according to the present invention, the traction frame can be rotated along the vertical direction so as to approach and separate from the storage portion, and between the pair of arms of the traction frame, the vertical direction is provided. Also included is an agricultural spraying device (claim 6) to which auxiliary legs that can be pivoted are attached.
According to this, when the spraying device is not used, the agricultural spraying device is made compact by rotating (folding) the traction frame so as to approach the storage unit and grounding the auxiliary leg in this posture. Can be easily stored in a narrow space. At this time, the support leg can be slid to prevent the directional wheel from protruding.
The auxiliary leg may be one or two or more.

A pair of left and right arms 11, 12 extending in parallel obliquely upward, and a traction frame 10 including a handle 13 disposed at right angles to the tips of the arms 11, 12, and between the arms 11, 12. And a directional universal ring 28 attached to the lower end of the support leg 20 that is attached in the middle of the longitudinal direction and extends obliquely downward.
The pair of left and right wheels W have a common rotating shaft s and are attached to both ends of the rotating shaft s passing through the horizontal bearing tube S. A substantially inverted U-shaped frame 3, 4 extending upward toward the diagonally forward and diagonally rear sides is fixed to the bearing tube S, and a pair of left and right along the front-rear direction is interposed between the frames 3, 4. A support band 5 is stretched horizontally. The interval between the pair of wheels W, W is set to the minimum value of the width of the uneven road sandwiched between the eaves and the like.

As shown in FIG. 1 and FIG. 3, above the pair of wheels W and the rotation shaft s, the frames 3 and 4 and a pair of left and right vertical frames 6 and 7 that stand individually from these frames, The storage unit 2 is formed of a substantially rectangular horizontal frame 8 fixed between the upper ends of the vertical frames 6 and 7, and the whole is a substantially rectangular parallelepiped. The storage unit 2 stores the tank T so that it can be taken in and out from the upper opening. The tank T is, for example, a rectangular parallelepiped container filled with liquid pesticide, and a cap c for closing the pesticide inlet is provided at the upper end surface. The vertical recess located on the front side surface has a pesticide on the nozzle N. A unit U containing a pump, a motor, a power source (none of which are shown), and the like for pumping and the like is fitted. A hose H communicating with the nozzle N extends from the lower part of the unit U.
A box 9 that can store the base portion of the nozzle N in a substantially vertical posture is attached to the outside of the rear vertical frames 7 and 7 in the storage portion 2, and an intermediate portion of the nozzle N is directly above it. A substantially U-shaped support frame 8 a that supports the horizontal frame 8 is fixed to the rear of the horizontal frame 8.

  As shown in FIGS. 1 to 3, the base end portions 11 a and 12 a of the pair of arms 11 and 12 constituting the traction frame 10 are rotatably attached to the middle of the frame 4 and are provided at the center of the handle 13. By pushing the grip 14 also serving as an anti-slip to the storage portion 2 side, the entire traction frame 10 can be folded close to the storage portion 10 or separated, and extended as shown in the figure. In the middle of the pair of arms 11 and 12 in the longitudinal direction, a frame 15 that is perpendicular and horizontal to these is fixed, and a flat plate 16 is fixed slightly obliquely in the middle of the frame 15, and in the center of the flat plate 16. The pipe 17 is fixed substantially along the vertical direction. The support leg 20 penetrates through the hollow portion of the pipe 17, and the support leg 20 can slide along the axial direction with respect to the pipe 17. That is, the support leg 20 is provided with a plurality of holes 19 along the axial direction, and the tip of a bolt 18 with a knob penetrating through the pipe 17 while being screwed from the outside enters the hole 19. Thus, the support leg 20 can slide along the axial direction with respect to the pipe 17 including the traction frame 10 and can be fixed at an arbitrary position.

As shown in FIGS. 1 to 3, the lower end of the support leg 20 is attached with a directional wheel 28, a holder 27 that pivotally supports the directional wheel 28, and a bearing portion 21 that is rotatably attached to the bottom surface of the holder 27. ing. As will be described later, the angle of the bearing 21 with respect to the surface (vertical surface) including the axial direction of the support leg 20 can be changed, and the bearing 21 including the directional ring 28 can be fixed at a desired coupling angle. ing.
As shown in FIGS. 1 to 4, a horizontal piece 52 is fixed to the rear of the bearing portion 21 by a bolt 53 or the like, and a pair of left and right inclined pieces 54 inclined obliquely downward are connected to the left and right sides of the horizontal piece 52. An inclined ring 60 is individually attached to the pair of inclined pieces 54 via a bearing 56. The pair of left and right inclined wheels 60 are symmetrically inclined so that the ground contact sides are separated from each other at a position in the width direction with the directional universal wheel 28 interposed therebetween.

As shown in FIGS. 1 to 3, rotating plates 31 and 32 that rotate along the vertical direction are pin-coupled on the outside of the arms 11 and 12 of the traction frame 10, and an operation lever 33 is interposed between them. It is installed horizontally. One rotary plate 32 is rotatably attached to a lower end portion on the front side of a swivel plate 34 that is substantially channel-shaped in side view, and one end of a wire 30 is coupled to the lower end portion on the rear side of the swivel plate 34. ing. The wire 30 is arranged along the outer side of one arm 12, and the other end thereof is provided in a radial direction from a substantially reverse U-shaped rotating rod 36 that is rotatably attached to the frame 4. The link piece 37 is coupled to the tip end.
As will be described later, brake pieces 40 having a substantially inverted L shape in side view are attached to both ends of the rotating rod 36, respectively, and can be brought into contact with the peripheral surfaces of the pair of wheels W by the movement of the wire 30. Has been. In order to maintain such a brake state, when the operation lever 33 is pulled toward the handle 13, a lock piece 35 having a claw piece 35 a that rotates upward to lock the operation lever 33 is provided inside the arm 12. It is mounted so as to be rotatable along the vertical direction.

As shown in FIGS. 1 to 3, a front end portion of a frame 41 that is substantially U-shaped in plan view is fixed to the rear side surface of the flat plate 16 disposed between the arms 11 and 12 of the traction frame 10. The rear end portions on both sides of the arm 41 are fixed inside the arms 11 and 12. The frame 41 is a reinforcing material for keeping the flat plate 16 in a predetermined posture together with the frame 15.
A frame member 42 having a substantially inverted L-shaped cross section and opened downward is attached to the arms 11 and 12 in the vicinity of each rear end of the frame 41, and the frame member 42 is rotated via a hinge 46 at the lower end edge thereof. A frame member 44 having a substantially L-shaped cross section that can be connected and separated is attached. The frame members 42 and 44 are formed into a box shape when folded by a retaining bar 43 with a knob penetrating the vertical piece on the front side in both, and only the frame member 44 is free by pulling the retaining bar 43 forward. Can be rotated downward. A pair of left and right support legs 49 hang down on the bottom surface of the frame member 44, and a substantially bell-shaped auxiliary leg 50 is attached to the lower end of each of them.
The pair of auxiliary legs 50 are made of hard rubber or the like, and are separated from the frame material 42 together with the frame material 44 by the above operation in a state where the traction frame 10 is rotated and folded toward the storage portion 2 side as will be described later. Then, when the agricultural spraying apparatus 1 is stored in a vertically long posture and compactly, when not in use, it is brought down and grounded to the ground.

FIG. 4 is an enlarged view of the vicinity of the support leg 20, the bearing portion 21, and the directional universal ring 28.
The support leg 20 is indicated by a straight arrow in FIG. 4 by allowing the tip of the knob bolt 18 penetrating the pipe 17 to enter any of the plurality of holes 19 opened along the axial direction. The traction frame 10 including the pipe 17 can be slid along a substantially vertical direction.
Further, support plates 22 and 24 are welded to the lower end of the support leg 20 along the front-rear direction, and support plates 23 and 25 are welded vertically to the upper surface of the bearing portion 21 adjacent to these. A pin 29 passes through the overlapping portion of the rear support plates 24 and 25, and an arc-shaped long groove 22a having the pin 29 as a rotation center is formed in the front support plate 22 on the support leg 20 side. ing. Bolts 26 penetrate horizontally through the long groove 22a and the front support plate 23 on the bearing portion 21 side, and a wing nut (not shown) is fastened to the male screw portion.
Therefore, when the support leg 20 is slid as described above so as to have a desired length, the bolt 26 is loosened and the pin 29 is the center of rotation, as shown by the curved arrows in FIG. The directional universal wheel 28 is rotated with respect to a plane (vertical plane) including the axial direction of the support leg 20 to obtain a desired coupling angle, and then the bolt 26 is refastened to smoothly rotate the directional universal ring 28. Can always ensure movement.

5 and 6 are schematic views showing the brake system of the spray device 1 and its operation.
As shown in FIG. 5, on the outside of the arm 12 constituting the traction frame 10 near the handle 13, rotating plates 31 and 32 that rotate along the vertical direction are pin-coupled, and between these tip portions, A horizontal operation lever 33 is connected. Furthermore, a front lower end portion of the swivel plate 34 having a substantially channel shape in a side view is rotatably attached to the front end portion of the rotation plate 32, and one end of the wire 30 is attached to the rear lower end portion of the swivel plate 34. Are combined. The wire 30 penetrates the guide 12b projecting from the arm 12 and is disposed along the outside of the arm 12, and the other end is rotatably attached to the frame 4 so as to be rotatable in a front view. 36 is coupled to the tip of a link piece 37 projecting radially from 36. For example, one end of a coil spring 38 having the other end coupled to the bearing cylinder S is coupled to the distal end of the link piece 37, and the rotational moment along the clockwise direction in FIG. Is given. Therefore, the pair of brake pieces 40 positioned at the upper ends of the angles 39 fixed to both ends of the rotating rod 36 are usually slightly separated from the peripheral surface of each wheel W as shown in FIG.

For example, when the spray device 1 is being transported while pulling the uneven road between the furrows, the operator may lose balance. At this time, when the operating lever 33 is rotated while being pulled toward the front side by a finger on one hand holding the handle 13 as shown in FIG. 6, as shown by the arrow in FIG. While rotating, it moves to the front side (right side in FIG. 6), and the wire 30 is pulled to the front side accordingly.
As a result, as the rotating rod 36 rotates counterclockwise against the compressive force of the coil spring 38, each brake piece 40 rotates downward as indicated by the leftmost arrow in FIG. The tip portion is in strong contact with the peripheral surface of each wheel W. Thereby, it will be in the locked state which stopped rotation of a pair of wheels W. Therefore, the operator can continue the spraying operation of agricultural chemicals by restoring the balance of the entire spraying device 1.

7 and 8 are schematic views showing a case where the traction frame 10 of the agricultural spraying apparatus 1 is folded and the auxiliary leg 50 is grounded and stored in a substantially vertical posture.
When the present spraying device 1 is not used, as shown by the arrow in FIG. 7, the handle 13 is brought close to the storage portion 2 and the wheel W, and the base portions 11a, The traction frame 10 is folded so as to be substantially parallel to the tank T with the frame 4 that rotatably supports the frame 12a as a rotation center. At this time, the support leg 20 and the directional wheel 28 may also be slid upward in advance as indicated by the arrows of a certain chain line so as to be closer to the tank T.

Next, the retaining bar 43 with a knob is pulled toward the near side against a spring pressure (not shown), and the lower frame member 44 is detached from the upper frame member 42, and as shown by the arrow in FIG. Rotate downward with 46 as the center of rotation. As a result, since the pair of auxiliary legs 50 are grounded with friction, the spray device 1 can be folded into a vertically long compact together with the pair of wheels W and stored in a narrow space. Further, the tank T can be taken out from the storage unit 2 and replaced with a new tank T in such a folded posture.
In addition, in order to maintain a folded state, you may provide the stopper which restrains the storage part 2 and the pulling frame 10 which mutually approached. Further, the frame members 42 and 44 are opened and closed by friction with the hinge 46, but in order to securely maintain the grounding state of the auxiliary leg 50, the frame members 42 and 44 are opened between each other as shown in FIG. A foldable stay in which a pair of upper and lower links 47 and 48 are pin-coupled may be arranged. Alternatively, a torsion spring (not shown) that applies pressure in a direction in which the frame members 42 and 44 are separated may be wound around the hinge 46.
Furthermore, in order to change from the folded state to the use state shown in FIGS. 1 to 3, the frame member 44 is folded directly under the frame member 42 by the reverse procedure described above, and the retaining rod penetrates through the front vertical pieces. After fixing at 43, the traction frame 10 may be rotated so as to be pulled away from the storage portion 2.

9 and 10 are schematic views showing the usage state of the agricultural spraying apparatus 1.
As shown in FIGS. 9 and 10, the three wheels, that is, the pair of wheels W and the directional wheel 28, are grounded along the longitudinal direction of the uneven passage R sandwiched between the left and right rods u and u. 9. Grasp the handle 13 of the frame 10 with one hand, and in the state of pulling and transporting the spray device 1 to the right (front side) in FIG. 9, grasp the base of the nozzle N at the tip of the hose H extending from the tank T with the remaining one hand. The pesticide or fertilizer is sprayed sequentially on one or both planted parts of the pair of ridges u and u. During this time, since the three wheels are always in contact with the passage R, the present spraying device 1 can perform the spraying operation efficiently and reliably with little effort.
In FIG. 9, the operator points the face, chest, etc. to the side of the spray device 1, but faces the face, chest, etc. to the right (front side), positions the spray device 1 behind the body, For example, the spraying operation may be performed in a state of being conveyed while being pulled, such as carry-back.
In addition, it is desirable for the operator to adjust the height of the traction frame 10 by sliding the support leg 20 with respect to the pipe 17 in advance according to his / her height and physique.

Further, in the case where the spray device 1 is moved in the passage R in which the pair of ribs u are recessed, the directional wheel 28 is guided to a local recess portion of the passage R, for example, on the left side in FIG. As shown in the figure, since the same inclined wheel 60 on the left side hits the road surface of the passage R as shown in FIG.
Alternatively, if any one of the pair of wheels W and the directional wheel 28 is fitted in the recess of the uneven passage R and the handle 13 of the traction frame 10 is simply pulled, the spray device 1 does not move easily. Alternatively, there is a possibility that the tank T may be inclined to lose the balance. In this case, the balance can be easily regained by immediately pulling the operation lever 33 toward the handle 13 and bringing the brake piece 40 into contact with the pair of wheels W so as to be in the stopped state. Therefore, it is possible to ensure the safety of workers and to prevent inadvertent spraying or dissipation of agricultural chemicals and fertilizers.
In order to maintain the brake state of the wheel W, the lock piece 35 provided on the inner side of the arm 12 may be rotated upward, and the claw piece 35a protruding in the middle may be wound around the operation lever 33. In addition, when moving to the field where the spraying operation is performed before or after or at a remote location, the intermediate portion and base portion of the nozzle N in a substantially vertical posture are accommodated in the box 9 and the support frame 8a provided behind the storage portion 2. By doing so, the present spraying device 1 including the hose H can be easily transported with one hand.

The present invention is not limited to the form described above.
For example, the interval between the pair of wheels W may be changeable.
Further, the storage portion may have a box shape including a bottom surface and four side surfaces.
In addition to the tank T, the storage unit may have a space for storing harvested vegetables, removed weeds, and the like.
Moreover, the said tank T is good also as two or more types of independent tanks, for example, the tank filled with the fertilizer, and the tank filled with the agrochemical.
Further, the pair of arms 11 and 12 constituting the traction frame 10 may have a nested structure, for example, and may be extendable and contractable along the axial direction.
Further, the inclined wheel 60 may be attached to the inner side surfaces of the pair of inclined pieces 54 via a bearing 56.
Furthermore, the spray device 1 of the present invention may be configured such that the inclined wheel 60 is omitted.
In addition, the auxiliary leg 50 may be one. Further, the auxiliary leg 50 is not limited to the pair of frame members 42 and 44 but may be moved up and down from any constituent member attached between the pair of arms 11 and 12 via an arbitrary mechanism. .

  According to the present invention, it is possible to effectively and reliably spray agricultural chemicals and fertilizers with a small amount of labor, regardless of age or gender, in relatively small part-time farmers and private vegetable gardens.
