  The present invention solves the problems described in the background art.For example, even in narrow alleys such as between adjacent fences in a field, it can easily move in a stable posture without damaging the fences and crops. It is another object of the present invention to provide an agricultural carrier that can perform agricultural work such as fertilization, weeding or harvesting, and can be folded thinly and compactly when not in use.

Means for solving the problems and effects of the device

In order to solve the above problems, the present invention arranges front wheels and rear wheels on the front and rear sides of a load carrier frame that supports a chemical tank and the like, and the load carrier frame that is positioned above the load carrier frame when used. The traction frames extending forward are folded in parallel with each other when not in use.
That is, the agricultural carrier of the present invention (Claim 1) is composed of a front frame, a rear frame, and a pair of left and right side frames, and is located above the load frame and the load frame having a rectangular shape in plan view. A front frame, a rear frame, and a pair of left and right side frames, and a rectangular-shaped cargo enclosure frame in plan view, and a plurality of shaft pins that protrude horizontally to the outside of each side frame of the cargo bed frame and the enclosure frame A plurality of swivel frames pivotally supported by a shaft pin on the load carrier frame side and pivotally supported by a shaft pin on the load enclosure frame side and rotatable along the front-rear direction; and the load carrier frame A front base having a front wheel provided near the center of the front frame of the frame and having a freely movable rolling direction, and a pair of rear parts disposed at positions extending rearward from the middle of the rear frame of the load carrier frame. Including a wheel, a wide rear wheel, or a crawler.

The farm work carrier can achieve the following effects (1) and (2).
(1) Since the front wheels freely rolling and the pair of rear wheels, wide rear wheels, or crawlers are arranged in the front-rear direction of the front frame and the rear frame of the load carrier frame, the width 2 is narrow. As a wheeled wheel or a three-wheeled vehicle, for example, even in narrow alleys with a width of about 20 to 30 cm, it is stable without damaging both side walls or left and right side walls and without damaging crops such as vegetables. Various farming work can be easily done with the posture.
(2) The loading platform frame and the loading enclosure frame are arranged along the front-rear direction via bearings provided on the upper and lower ends of a plurality of (for example, two) shaft pins protruding outward from the respective side frames. By rotating a plurality of (for example, four) swivel frames, the two can be rotated along the front-rear direction. Therefore, when the loading frame is moved rearward and downward, the plurality of revolving frames are located outside the loading frame and the loading frame, so that the loading frame and the loading frame are directly connected to each other. Fold it in contact. As a result, the storage state in which the overall thickness is relatively thin and compact can be achieved.

For example, a material obtained by bending a stainless steel tube having a diameter of several centimeters, an aluminum tube, or the like is used as the loading platform frame, the loading frame, the turning frame, the pulling frame, and the locking frame.
The shaft pin is made of ordinary steel, bearing steel, tool steel, or the like.
Furthermore, the loading platform frame and the loading enclosure frame have the same size as each other or a similar rectangular (square or rectangular) shape in plan view.
Further, the “pivot support” means rotatable or pivotable.
Further, the “center side of the front frame of the load carrier frame” means near the center in the axial direction of the front frame, and the “middle of the rear frame of the load carrier frame” means at least the axial direction of the rear frame. It refers to a region excluding both ends, and includes the vicinity of the center in the axial direction.
Further, the “front wheel having a freely rolling direction” is a so-called directional wheel.
Further, the pair of rear wheels may have a form in which a pair of double wheels (double tires) are adjacent to or separated from each other in addition to a form in which the pair of rear wheels are pivotally supported with a space between the pair of wheels.
Further, the wide rear wheel has a tire width of at least 10 cm or more, more preferably 15 cm or more.
In addition, the crawler includes, for example, a configuration in which a pair of rubber crawlers are arranged with a space therebetween, and also includes a configuration in which a single rubber crawler is formed. You may comprise either a parallel horizontal attitude | position or the inclination attitude | position which inclines with respect to the ground.

Further, according to the present invention, the support frame provided in front of the front frame of the load carrier frame includes a pair of left and right long side frames along the front-rear direction and a grip for connecting between the ends of the pair of long side frames. A traction frame composed of a frame is connected to the support frame via a hinge provided on the base end side of each of the long side frames, so that the traction frame is rotatably connected along the vertical direction and the front-rear direction. A farm carrier (claim 2) is also included.
According to this, for example, a farmer operates the spray nozzle with the remaining one hand while holding the gripping frame of the towing frame with one hand and moving the farmwork carrier by pulling forward between the vines of the field. By spraying a mist-like pesticide solution with relatively little effort from a chemical solution tank placed on the cargo bed frame and loaded around the upper periphery of the load frame. It becomes possible to easily weed and collect weeds with the remaining one hand (effect (3)).
The pesticide spraying operation can be performed while holding the gripping frame of the towing frame with one hand and pushing the main farm work carrier backward to retract it.

Further, according to the present invention, a horizontal frame connecting between the pair of long side frames is fixed in the middle of the pair of left and right long side frames in the traction frame, and the load enclosure is attached to the horizontal frame. By locking a locking portion provided at a distal end of a locking frame pivotally supported on the front frame of the frame, the loading frame, the load frame positioned above the loading frame, and the plurality of frames An agricultural carrier (Claim 3) is also included, in which the position of the swivel frame and the pair of left and right long side frames in the traction frame that are inclined with respect to each other can be regulated.
According to this, by locking the locking portion provided at the distal end of the locking frame pivotally supported by the front frame of the cargo frame to the horizontal frame, the load frame, The position of the frame, the plurality of swivel frames, and the traction frame can be regulated with respect to each other. Therefore, since the entire space surrounded by the cargo frame above the cargo bed frame can be solidly configured, a load such as a relatively heavy chemical tank can be loaded, and the traction frame can be grasped to the front side. While moving, it can stably carry out various agricultural operations such as spraying agricultural chemicals (effect (4)).
In addition, the said horizontal frame is good also as a form which has a through-hole which receives the latching | locking part of the said latching frame, for example.

Further, in the present invention, the plurality of revolving frames are rotated from the vertical posture to the rear side, the load enclosure frame and the locking frame are translated upward on the rear side of the load carrier frame, and parallel to the load carrier frame. A carrier for farm work (Claim 4) is also included in which the upper part of the pair of rear wheels, the wide rear wheel, or the crawler enters the inside of the enclosure frame.
According to this, the pair of rear wheels having a relatively large diameter when the luggage frame and the locking frame are translated upward on the rear side of the bed frame and parallel to the bed frame, Even if it is a wide rear wheel or a crawler having a relatively large length, these upper parts enter the inside of the luggage frame. Therefore, the effect (2) can be guaranteed.
In addition, since the latching frame translated parallel to the rear side of the cargo carrier frame together with the cargo frame is located at the center in the width (lateral) direction of the cargo frame, it interferes with the latch frame. In order to prevent this, it is desirable to set in advance such that the locking frame enters between a pair of rear wheels or a pair of crawlers.

In addition, the present invention includes a farm carrier (Claim 5) in which a pair of auxiliary wheels that extend obliquely downward and symmetrically are attached to both sides of the front wheel.
According to this, when moving along the front-rear direction by either the front wheel and a pair of rear wheels, the front wheel and a wide rear wheel, or the front wheel and a single or a pair of crawlers, Thus, since the pair of auxiliary wheels are arranged in a substantially C-shaped posture, the effect (1) can be reliably achieved even in an uneven alley.
The pair of auxiliary wheels are arranged on a flat ground so as to float with a slight gap from the ground.

A pair of rear wheels W and a front wheel w arranged in front of the front frame 3 of the loading frame 2 near the center and having a freely rolling direction are provided.

Each of the loading frame 2 and the loading frame 12 is, for example, a square shape having a side of about 30 cm in a plan view or a rectangular shape having a length in the front-rear FR direction of about 21 cm and a width of about 31 cm. It is. At the center of each of the front frame 3, the rear frame 4, and the pair of side frames 4, the load support frames 3 a, 4 a, and 5 a having a П shape in a side view are shown in FIG. May be erected at a position where there will be no hindrance during folding, which will be described later.
Two load support frames 6 along the front-rear FR direction are horizontally disposed inside the load carrier frame 2. The load support frames 6 may be three or more, or may have a lattice shape that intersects vertically and horizontally in a plan view.
The rear wheel W and the front wheel w are pneumatic tires or solid no-puncture tires made of synthetic rubber or synthetic resin and having the required flexibility.
As shown in FIGS. 1 and 3, the pair of rear wheels W are joined to the vertical plate 8 welded to the center portion of the rear frame 5 of the cargo carrier frame 2 and the rear R side of the vertical plate 8. A pair of side pieces in the support frame 9 are axially supported symmetrically via a U-shaped support frame 9 in plan view. Such rear wheels W each have a diameter of about 21 cm and a width of about 7 to 9 cm.

  1 and 2, the front wheel w is welded in a horizontal posture to a front frame 17 of a channel frame 16 welded in a horizontal posture to the center side of the front frame 3 of the cargo bed frame 2. It is attached to the bottom surface of the front stand 18 via a holder 20 including a bearing. On the bottom surface of the front base 18, a pair of support fittings 19 extending symmetrically on the left and right diagonally lower sides are fixed to the front F side of the front wheel w. A pair of auxiliary wheels aw that are symmetrical in the shape of a letter C and that go diagonally downward are pivotally supported. The auxiliary wheel aw is made of hard resin or hard rubber. The maximum width between the pair of auxiliary wheels aw is recommended to be about 40 to 60 cm.

Further, as shown in FIGS. 1 to 3, at both ends of the front frame 3 of the load carrier frame 2, base end portions of a pair of left and right support frames 22 extending forward and obliquely upward while curving from the middle. A substantially L-shaped support material 21 is welded to the horizontal front frame 23 connecting the tip portions of the pair of support frames 22 in a side view. One side of the hinge h is horizontally attached to the end edge of the support material 21 on the side of the loading frame 2. The other end of the hinge h is connected to a rear end edge of the channel-shaped rotating member 24 having a flat side view so as to be rotatable along the front-rear (F-R) direction. A pair of left and right long side frames 26 extend obliquely forward from the left and right ends. The distal end portions of the pair of long side frames 26 are connected by a horizontal gripping frame 27 along the width direction, and these constitute the traction frame 25. In the middle of the pair of long side frames 26 in the axial direction, a horizontal frame 28 that connects the two horizontally is welded along the width direction.
A support member (stay) (not shown) may be attached between the bottom surface of the support member 21 and the top surface of the front table 18.

At the center of the front plate of the rotating member 24, a knob 29 (not shown) for screwing into a screw hole penetrating the front plate is located, and the bolt is connected to the support member 21. By screwing into a screw hole (not shown) penetrating the front plate, the rotary member 24 and the support member 21 are in a substantially parallel posture to each other and are restrained (locked). That is, by loosening the knob 29, the traction frame 25 can be rotated upward and rearward R about the hinge h.
In addition, as shown in FIGS. 1 and 2, a sleeve 7 is rotatably mounted in the middle of the front frame 13 of the cargo enclosure frame 12, and the left and right sides constituting the locking frame 30 are attached to the sleeve 7. The base end portions of the pair of side frames 31 are fixed. For each front end portion of the pair of side frames 31, a pair of vertical frames 32 that bend downward substantially at a right angle and a locking portion 33 that is U-shaped when viewed from the front are connected.

As shown by the one-dot chain line in FIG. 1, the locking frame 30 is rotatable upward and rearward R about the sleeve 7 as a rotation center.
That is, as shown in FIGS. 1 to 3, the locking frame 30 has the load frame 12 positioned directly above the loading frame 2 and the rotating member 24 on the base end side of the traction frame 25 is In the state of being restrained by the support member 21, the locking portion 33 is locked to the horizontal frame 28 of the traction frame 25, whereby the horizontal loading platform frame 2, the horizontal loading frame 12, and four The vertical revolving frame 12 and the pair of long side frames 26 which are inclined postures of the traction frame 25 are restricted so that they cannot move relative to each other.
The loading platform frame 2, the loading frame 12, the turning frame 10, the channel frame 16, the support frame 22, the traction frame 25, and the locking frame 30 are, for example, a steel bar made of stainless steel having a diameter of about 1 to 2 cm. A pipe material is used and further bent appropriately.

In the use state shown in FIG. 1, for example, a chemical tank (not shown) filled with an agrochemical solution is supported in the rectangular parallelepiped loading space surrounded by the loading frame 2 and the loading frame 12. It is stored on the frame 6. For example, when storing a vertically long chemical tank in the cargo space and pulling the gripping frame 27 of the traction frame 25 to the front F side with one hand and operating the spray nozzle with liquid pesticide or fertilizer with the remaining one hand, Tabata Even a relatively narrow ground GL located between the front and rear can easily move in a stable posture as a relatively narrow three-wheeled vehicle with a front wheel w and a pair of rear wheels W. Agricultural work such as spraying can be performed. In addition, the front wheels w and the pair of rear wheels W do not damage the pods on both sides or damage crops such as vegetables grown on such pods. Furthermore, since the pair of auxiliary wheels aw are disposed in the vicinity of the front wheel w, it is possible to suppress the possibility of swinging in the left and right (width) direction due to the unevenness of the ridges and the ground GL. Therefore, it becomes easy to perform safe and comfortable farm work.
The chemical solution tank is provided with a spray nozzle, a battery for a motor that drives a pump that pumps the agrochemical solution to the nozzle, and a backpack belt.

Here, based on FIG. 4, FIG. 5, the function etc. which fold the said agricultural work melt | dissolution carrier 1 along the front-back FR direction are demonstrated.
First, as shown by the arrows in FIGS. 4A and 4B, the pair of side frames 31 in the locking frame 30 and the side frame 31 with one hand with the sleeve 7 on the rear R side as the rotation center. Is lifted obliquely upward on the rear R side and the locking portion 33 is detached from the horizontal frame 28, and then rotated about 180 degrees to the rear R side and placed on the cargo enclosure frame 12.
In this state, hold the appropriate position of the upper load-closing frame 12 with the remaining one hand, and as shown by the arrows in FIG. The bearings 11 on the side of the load carrier frame 2 are rotated about the center of rotation, and the cargo enclosure frame 12 including the locking frame 30 is translated in the rear R side and obliquely downward while maintaining the horizontal posture.

As a result, the load frame 12 rotated to the rear R side along the solid line arrow in FIG. 5A is in a horizontal posture on the rear side R and parallel to the load frame 2. It becomes. At this time, the four revolving frames 10 are in a substantially horizontal posture slightly inclined on the outer sides of the cargo bed frame 2 and the cargo frame 12.
In the state shown in FIG. 5A, the upper or upper end portions of the pair of rear wheels W enter the inside of the luggage frame 12. Further, the pair of side frames 31 in the locking frame 30 is located above the support frame 9 located between the pair of rear wheels W.

Therefore, a long cargo bed having a rectangular shape in plan view and gently sloping in the front-rear direction (F-R) is formed across the cargo bed frame 2 and the cargo frame 12 located near the same horizontal plane. The For example, by placing a rectangular parallelepiped harvesting container (not shown) made of resin and long in the front-rear direction on such a long bed, for example, in the harvesting field, orchard, home garden or flower bed, the traction When the grown vegetables and fruits are sequentially harvested in the harvesting container while moving while pulling the frame 25, it is possible to efficiently perform the harvesting work with relatively little effort. The harvest container may be used for collecting weeds or careless garbage.
Next, the knob 29 is turned to retract the bolt, and the locked state between the rotating member 24 and the supporting member 21 is released. Further, as shown by the dashed line arrow in FIG. 5A, the pair of long side frames 26 and the rotating member 24 in the traction frame 25 are arranged on the rear R side with the hinge h as the rotation center. Rotate 120 degrees.

As a result, as shown in FIG. 5B, the pair of long side frames 26 in the traction frame 25 are placed so as to overlap the cargo enclosure frame 12. At this time, the locking portion 33 of the locking frame 30 enters between the pair of long side frames 26.
In this state, for example, a C-shaped or S-shaped hanging bracket (not shown) is bridged between the cargo bed frame 2 and any of the long side frames 26, and both are restrained. In the horizontal position of 5 (B), or in an upright position rotated about 90 degrees from FIG. 5 (B), the farm work melting carrier 1 when not in use is folded thinly and stored compactly. Can do.
Therefore, according to the agricultural work melt carrier 1 having the structure and function as described above and having an action, the effects (1) to (4) can be achieved.

In FIG. 6, instead of the pair of rear wheels W, a single wide rear wheel WW is arranged through a channel-shaped support frame 34 in a plan view welded to the center of the rear frame 4 of the load carrier frame 2. It is the same bottom view as the above which shows the installed state. Such a rear wheel WW is a pneumatic tire or a no-puncture tire having a width of at least 10 cm (for example, about 15 cm).
In the embodiment using the rear wheel WW, in order to avoid interference with the pair of side frames 31 in the locking frame 30, the width of the intermediate portion of the pair of side frames 31 is set to be larger than the width of the rear wheel WW. It should be set a little wider.

In FIG. 7, instead of the pair of rear wheels W, a pair of support bases 35 along the front-rear FR direction are individually attached to both side pieces of the support frame 9 and are attached to both ends of the support bases 35. FIG. 4 is a side view similar to the above showing a state in which a pair of crawlers (infinite track) C made of synthetic rubber wound in an oval shape in a side view is disposed between a pair of front and rear sprocket wheels that are pivotally supported. The width of the crawler C is about 8 cm to 12 cm.
The pair of crawlers C is not limited to a horizontal posture, and may be a posture inclined such that the rear R-side sprocket wheel 36 is on the ground GL side and the front F-side wheel 36 is floated upward. Moreover, it is good also as a form which attached the single crawler C whose width | variety is about 15 cm or more to the center part in the rear frame 4 of the carrier frame 2 similarly to the above.

  The above-described effects (1) to (4) are also obtained by the farm work melt carrier 1 having the form including the wide rear wheel WW shown in FIG. 6 or the form including the pair or single crawler C shown in FIG. It becomes possible.

The present invention is not limited to the form described above.
For example, the loading platform frame 2, the loading enclosure frame 12, the revolving frame 10, the traction frame 20, and the like may be formed of a hard resin frame material such as engineering plastic.
In addition, on the front frame 3 of the loading platform frame 2, a single or a plurality of load receiving frames that prevent the load from dropping off to the front F side are provided at positions that do not interfere with the pair of long side frames 26 in the traction frame 25. May be installed.
Further, a load receiving frame similar to the above may be provided upright on the pair of left and right side frames 5 in the cargo bed frame 2.
In addition, a brake mechanism described in Patent Document 1 may be provided in the vicinity of the pulling frame 25, the loading frame 2, and the pair of rear wheels W.

  According to the present invention, even in narrow alleys such as between adjacent ridges in a field, it is possible to easily move in a stable posture without damaging the ridges and crops, and to perform farming operations such as fertilization, weeding or harvesting. When not in use, it is possible to reliably provide a farm carrier that can be folded thinly and compactly.
