DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
1 to 9 show an embodiment of an agricultural cart according to the present invention. As shown in FIGS. 1 to 6, the agricultural cart 1 (hereinafter referred to as the cart 1) includes a base 2 and a tray mounting shelf 3. As shown in FIG. 5, the pedestal 2 connects four L-shaped angles 4 a to 4 d welded and fixed in a square shape (rectangular shape in the figure) in plan view to the left and right L-shaped angles 4 a and 4 c. A plurality of (two in the figure) crosspieces 4e are provided. A mounting surface 4 is formed on the upper surface of the base 2 by the horizontal walls of the L-shaped angles 4a to 4d and the crosspiece 4e.

  In addition, the pedestal 2 has two connecting pipes 5 each having an L-shaped bent end portion welded and fixed to an intermediate portion between the front and rear L-shaped angles 4b and 4d. Axle support pipes 6 having substantially the same length as that of the mounting surface 4 in the left-right width direction are fixed to the lower surfaces of the front and rear predetermined positions by welding. An axle 7 longer than the axle support pipe 6 by a predetermined dimension is loosely fitted in the pair of axle support pipes 6, so that the axle 7 moves axially in the axle support pipe 6 (see FIG. 5). In other words, the axle 7 is movable in the left-right width direction with respect to the placement surface 4.

  As shown in FIGS. 7 and 8, the axle support pipe 6 is provided with a through hole 8 in a peripheral wall at an intermediate position in the longitudinal direction, and a nut 9 is fixed to the outer peripheral surface of the through hole 8 by welding. Yes. Further, the axle 7 loosely fitted to the axle support pipe 6 is notched over the entire area in the axial direction on the circular outer peripheral surface, thereby forming a flat surface 7a as a fixed surface.

  The front end of the axle fixing bolt 10 screwed into the nut 9 abuts on the flat surface 7a, so that the axle 7 and the axle support pipe 6 are fixed and maintained at a predetermined position. 7, the axle 7 and the axle support pipe 6 are released from the fixed state so that the axle 7 can move in the axle support pipe 6 in the axial direction b. The flat surface 7a provided on the axle 7 is not limited to the configuration provided in the entire region of the axle 7 in the axial direction, and may be provided with a predetermined length in an intermediate portion. In this case, both the side walls of the flat surface 7a and the axle are fixed. The engagement with the bolt 10 may restrict the axial movement of the axle 7 more than necessary.

  At predetermined positions on both ends of the axle 7, for example, wheels 11 having tubeless urethane tires are rotatably attached by predetermined bearings. Of the pair of left and right wheels 11, the axle 7 on the axially outer side of the wheel 11 on one side in the width direction of the mounting surface 4 (the right side in FIGS. 1 and 2) has a groove as one rotating member. A roller 12 is rotatably attached to each other. A wheel 7 on the other side in the width direction of the mounting surface 4 (the left side in FIGS. 1 and 2) on the outer side in the axial direction of the wheel 11 is a circle as the other rotating member. Each of the columnar rollers 13 is rotatably attached.

  The grooved roller 12 is a pair of pipe-shaped pipes having a diameter of 25 to 30 mm, for example, shown by a two-dot chain line in FIG. The rails 14a and 14b have U-shaped grooves 12a that can be engaged from above. The cylindrical roller 13 is formed to have a predetermined length L (see FIG. 11) wider than the grooved roller 12 and is rotatably attached to the axle 7.

  The outer diameters of the shaft-equipped roller 12 and the cylindrical roller 13 are set smaller than the outer diameter of the wheel 11 (250 to 300 mm), respectively. 3 and 4, the bottom surface position of the U-shaped groove 12a of the grooved roller 12 and the lower end position of the outer peripheral surface of the cylindrical roller 13 are the dimension t1 between the bottom surface of the U-shaped groove 12a and the center of the axle 7. And the dimension t2 between the outer peripheral surface of the cylindrical roller 13 and the center of the axle 7 (the outer diameter of the bottom surface of the U-shaped groove 12a and the outer diameter of the cylindrical roller 13, for example, 80 mm) are set to be substantially the same. Yes. The wheel 11, the grooved roller 12 and the cylindrical roller 13 are restricted from moving in the axial direction of the axle 7 by a stopper or the like.

  On the outer surface of the L-shaped angle 4a at the front portion of the mounting surface 4 of the pedestal 2, grip support members 15 are fixed by welding to both ends in the width direction. The handle support member 15 has, for example, a non-penetrating handle insertion hole in the vertical direction, and a fixing bolt 18 such as a butterfly bolt for fixing the lower end portion of the handle 17 fitted and inserted into the handle insertion hole. Both ends of the lower end of the handle 17 can be attached to and detached from the pair of handle support members 15 by rotating the fixing bolt 18. The handle 17 has a vertical portion 17a and a gripping portion 17b inclined forward with respect to the vertical portion 17a.

  In addition, a column support member 16 is welded and fixed to the inside of the handle support member 15, and this column support member 16 is also fixed to the outer surface of the rear L-shaped angle 4 d by welding. At this time, the positional relationship between the four column support members 16 matches the positional relationship between the four columns 21 of the tray mounting shelf 3 described later. The four column support members 16 also have column insertion holes and fixing bolts 19 similar to the handle support member 15, and the lower ends of the four columns 21 of the tray mounting shelf 3 are detachable. Yes. The L-shaped angles 4a to 4d, the crosspieces 4e, the connecting pipe 5, the axle support pipe 6, the axle 7, the handle support member 15, the column support member 16 and the like constituting the pedestal 2 are all made of aluminum or aluminum alloy. Thus, the weight of the base 2 is reduced.

  As shown in FIG. 6, the tray mounting shelf 3 includes a column 21 composed of four pipes, and a two-stage mounting surface 22 disposed in the height direction between the columns 21. Yes. Each mounting surface 22 is configured in the same manner as the mounting surface 4 of the pedestal 2 by welding and fixing four L-shaped angles 22a to 22d and two crosspieces 22e. The shape) is also set to be the same as the placement surface 4.

  The mounting surfaces 22 and 4 of the tray mounting shelf 3 and the pedestal 2 are mounted on the mounting surfaces 22 and 4 such that the vertical walls of the L-shaped angles 22a to 22d and 4a to 4d are positioned on the outer periphery thereof. Falling to the outside of the harvesting tray 24 or the like to be placed is prevented. Further, caps 23 are fitted in the upper end openings of the respective columns 21. The support column 21, L-shaped angles 22a to 22d, and crosspieces 22e of the tray mounting shelf 3 are made of aluminum or aluminum alloy in the same manner as the pedestal 2 to reduce the weight.

  Next, an example of a method of using the cart 1 configured as described above will be described. First, a pair of trolleys 1 on which tray mounting shelves 3 are attached to a pedestal 2 are moved to a house where strawberries are cultivated and laid along adjacent straws in the house to be harvested. Set on the rails 14a and 14b. In this set, the grooved roller 12 is placed on one rail 14a and the U-shaped groove 12a is engaged with and supported by the rail 14a, while the cylindrical roller 13 is placed on the other rail 14b. While supporting with the contact support part 20 (refer FIG. 9), the axle fixing bolt 10 is loosened, the fixed state of the axle 7 and the axle support pipe 6 is cancelled | released, and it is set as the state which permitted the movement of the axial direction A of the axle 7. Is done.

  In this set state, the tray 24 (see FIG. 6) made of resin, for example, is placed on the two placement surfaces 22 of the pedestal 2 and the tray placement shelf 3, and the carriage 1 is attached to the rail 14a, While moving along 14 b, the strawberries of the adjacent strawberries are harvested and stored in the tray 24. When the strawberries are harvested and the leaves grow out due to variations in the growth of the strawberry seedlings and protrude outside the straw, the tray mounting shelf 3 of the carriage 1 is This is performed by moving in the direction (the axial direction of the axle 7).

  That is, the tray mounting shelf 3 with respect to the base 2 of the carriage 1 has an axle support pipe 6 with an axle 7 as shown in FIG. 9A in a normal state where the carriage 1 is used as an ordinary carriage 1 as will be described later. The axle fixing bolt 10 is fastened to a position substantially at the center in the axial direction, that is, at a position where the distances L1 and L2 between the pair of wheels 11 and the end faces of the axle support pipe 6 are set substantially the same. And in the harvesting state which harvests strawberries, the axle fixing bolt 10 is loosened to release the fixing state of the axle 7 and the axle support pipe 6, and the carriage 1 is moved on the pair of rails 14a, 14b.

  When the carriage 1 moves along the rails 14a and 14b, as described above, if the leaves or the like protrude from the intercostal space or the like, the tray mounting shelf 3 is pushed by hand in the width direction of the eyelid, and FIG. ) Or in the anti-extrusion direction of the leaves as indicated by arrows (b) and (c) in FIG. Due to the movement of the tray mounting shelf 3 in the axial direction of the axle 7, the tray mounting shelf 3 moves to one side of the furrow (the side where the leaves or the like do not protrude), and the tray mounting shelf 3 The trolley 1 (the pedestal 2 and the tray mounting shelf 3) moves along the rails 14a and 14b and the strawberry harvesting operation is performed while contact with the three leaves is prevented.

  In addition, the pair of rails 14a and 14b laid in a long house has a long rail 14a and 14b, and therefore, the interval L3 between the rails 14a and 14b shown in FIG. 9A may not be constant. However, in the case of the carriage 1, since the cylindrical roller 13 having a wide predetermined length is used, as shown in FIG. 10, the interval L3 between the pair of rails 14a and 14b is indicated by a two-dot chain line. Even if it becomes wide, the contact support portion 20 moves in the axial direction on the outer peripheral surface of the cylindrical roller 13, and the change (variation) in the distance L3 is absorbed.

  That is, as shown in FIG. 11, when the distance L3 between the pair of rails 14a and 14b changes, the groove 12a of the grooved roller 12a is engaged with one rail 14a, and the position is fixed. From the longitudinal direction of the cylindrical roller 13 in which the position of the contact support portion 20 of the rail 14b is the axial direction with respect to the outer peripheral surface of the cylindrical roller 13 that is simply placed and supported on the other rail 14b (left and right in the figure) Then, it moves like the two-dot chain line arrow. At this time, since the length L of the cylindrical roller 13 is set in advance to a dimension that can accommodate the maximum change in the distance between the rails 14a and 14b, the cylindrical roller 13 does not fall off the rail 14b. The carriage 1 moves smoothly on the pair of rails 14a and 14b.

  For example, when a predetermined amount of harvested strawberries is stored in all the trays 24, the cart 1 set on the rails 14a and 14b is lowered from the rails 14a and 14b, and the four wheels 11 are housed. It touches the inside ground. In this state, the carriage 1 is moved (unloaded) to the outside of the house using the handle 17 in a state where the axle fixing bolt 10 is tightened to prevent the tray mounting shelf 3 from moving in the axial direction of the axle 7. Since the movement of the carriage 1 is performed by the rotation of four relatively large wheels 11, even if the harvested strawberries are placed and the carriage 1 is heavier, the carriage 1 can be moved stably and smoothly. (Transport) can be performed.

  Moreover, in the said trolley | bogie 1, since the tray mounting shelf 3 is attached to the base 2 so that attachment or detachment is possible, the tray mounting shelf 3 is removed by loosening the fixing bolt 19 and removing the support | pillar 21 from the support | pillar support member 16. 5 can be removed from the pedestal 2 to obtain the state shown in FIG. 5, and can be used as a general carriage having the handle 17 in this state. In this case, a cardboard box or the like containing a large number of strawberry storage boxes for shipping is placed on the placement surface 4 of the pedestal 2, or general transported goods other than the harvested agricultural products are placed on the placement surface 4. It is placed on top and transported.

  Furthermore, since the handle 17 is detachably attached to the support column 15 of the pedestal 2, when the carriage 1 is not used, the fixing bolt 19 is loosened and the lower end of the handle 17 is removed from the handle support member 15. Thus, the handle 17 is removed from the pedestal 2, that is, the carriage 1 is divided (disassembled) into the three members of the pedestal 2, the handle 17, and the tray mounting shelf 3, for example, the carriage 1 can be stored and managed.

  In other words, in the case of the carriage 1, the axle 7 with the grooved roller 12 and the columnar roller 13 rotatably attached to the outside of the wheel 11 is loosely fitted to the axle support pipe 6 of the pedestal 2, and the axle 7 is attached to the pedestal 2. Can be moved in the axial direction, the harvesting operation can be performed while moving the tray mounting shelf 3 attached to the pedestal 2 in a direction (width direction of the ridge) perpendicular to the longitudinal direction of the rails 14a and 14b. . Further, by removing the tray mounting shelf 3 from the pedestal 2, the pedestal 2 can be used as a general cart with a handle 17.

  Thus, according to the cart 1, the cylindrical roller 13 is mounted on the rail 14b while the grooved roller 12 outside the wheel 11 of the axle 7 is engaged and supported by the rail 14a laid along the strawberries. And the contact support 20 between the rail 14b and the cylindrical roller 13 is movable in the axial direction of the axle 7, and the base 2 and the tray mounting shelf 3 move along the rails 14a and 14b. Therefore, even when the strawberry leaves or the like are stretched and the intervals such as the spaces are narrowed, the rail 14b moves in the axial direction on the outer peripheral surface of the cylindrical roller 13, and the cylindrical roller 13 is removed from the rail 14b. For example, the carriage 1 can be moved while accurately responding to changes in the distance between the rails 14a and 14b.

  In particular, since the pedestal 2 to which the tray installation shelf 3 is attached is movable in the axial direction of the axle 7, the tray placement shelf 3 can be attached to the axle 7 even when the interval between the spaces between the strawberries is reduced. By manually pushing in the axial direction, the tray mounting shelf 3 can be easily moved in the width direction of the bag. Therefore, the cart 1 can be smoothly moved on the rails 14a and 14b along the ridge without contacting the tray mounting shelf 3 with the leaves extending between the ridges, etc., and the work efficiency of the strawberry harvesting work can be improved. Can be sufficiently increased.

  Further, since the handle 17 is provided in a standing state at the front end portion of the pedestal 2, by using this handle 17, the pedestal 2 from which the tray mounting shelf 3 has been removed can be used as a general carriage. Usability of the carriage 1 can be improved, and various trays 24 can be stably placed on the placement surfaces 22 and 4 of the tray placement shelf 3 and the pedestal 2 so that they can be applied to harvesting agricultural products in various cultivation forms. The cart 1 with high versatility can be obtained.

  In addition, one of the rotating members is formed of a grooved roller 12 that engages with the rail 14a, the other of the rotating members is formed of a cylindrical roller 13 having a predetermined length, and the rails 14a and 14b are pipe-shaped. Even if the pair of rails 14a and 14b are long and the distance between them is not constant, the pipe-shaped rail 14b moves in the axial direction while being supported by the contact support portion 20 on the outer peripheral surface of the cylindrical roller 13, and the carriage 1 is moved. It can be reliably moved on the rails 14a and 14b.

  Furthermore, the outer diameter of the grooved roller 12 and the cylindrical roller 13 is set to be smaller than the outer diameter of the wheel 11 and is disposed rotatably on the axle 7 outside the wheel 11 respectively. The carriage 1 lowered from the rails 14a and 14b can be moved by the wheel 11 having a large diameter and a tire, and the carriage 1 storing the harvested strawberries can be easily and reliably moved.

  Further, since the mounting surface 4 capable of storing the tray 24 is formed on the upper surface of the pedestal 2, the tray 24 can be mounted on the mounting surface 4 on the upper surface of the pedestal 2, You can increase the number of strawberry storage by increasing the number. In addition, since the handle 17 is detachably disposed at the front end portion of the pedestal 2 and the tray mounting shelf 3 is detachably disposed on the pedestal 2, the carriage 1 can be formed of three members, The assembly and disassembly work can be easily performed, and the cart 1 can be stored and managed easily.

  In addition, since the flat surface 7a on which the tip of the axle fixing bolt 10 of the axle support pipe 6 abuts is provided on the peripheral surface of the axle 7, the tip of the axle fixing bolt 10 is reliably brought into contact with the flat surface 7a of the axle 7. Thus, when the pedestal 2 and the tray mounting shelf 3 can be fixed and moved without using the grooved roller 12 or the cylindrical roller 13 or when the tray mounting shelf 3 is removed and moved, the movement of the carriage 1 Can be performed stably and smoothly.

  By the way, in the said embodiment, although a pair of rotation member was formed with the grooved roller 12 and the wide cylindrical roller 13, it can move to an axial direction instead of the cylindrical roller 13, for example, as shown in FIG. A grooved roller 26 can also be used. The grooved roller 26 in this case is provided with a U-shaped groove 26a similar to the grooved roller 12 on the outer peripheral surface, and is attached to the axle 7 by a slide bearing 27 so as to be rotatable and movable in the axial direction A. Yes. Further, the axial movement of the roller 26 with the shaft is regulated by a stopper 28 fixed to the end surface of the axle 7 by a bolt 29 and a bearing portion of the wheel 11.

  Also in this rotating member, the movement of the grooved roller 26 in the axial direction can easily cope with a change in the distance L3 between the pair of rails 14a, 14b, and the pair of rotating members are the grooved rollers 26, 12. Therefore, the engagement state with the pipe-shaped rails 14a and 14b is stabilized, and for example, the rollers 12 and 26 are surely prevented from falling off from the rails 14a and 14b, so that the smoother movement on the rails 14a and 14b is achieved. Movement becomes possible. Although not shown, it is of course possible to form the pair of rotating members with the grooved roller 26 shown in FIG. 12, that is, with the grooved roller 26 that is movable in the axial direction.

  In the above-described embodiment, the tray mounting shelf 3 is provided with two stages of mounting surfaces 22. However, for example, three or more stages of mounting surfaces 22 can be provided, or a separate tray mounting shelf 22 can be provided. By removing the cap 23 at the upper end of the support column 21 of the tray mounting shelf 22 and inserting the support column, the mounting surface 22 can be added as a structure in which a plurality of tray mounting shelves 22 are stacked. Further, the mounting surface 22 itself of the tray mounting shelf 3 is not limited to a mode in which the tray 24 is mounted from above, but a mode in which the tray 24 can be stored and mounted in a sliding manner from the front-rear direction or the side can also be adopted. .

  Moreover, in the said embodiment, although the grooved roller 12 and the cylindrical roller 13 were rotatably arrange | positioned at the axle shaft 7 outside the wheel 11, you may arrange | position at the axle shaft 7 inside the wheel 11, The grooves of the grooved rollers 12 and 26 are not limited to the U-shape, and may be formed as, for example, V-shaped grooves or flat grooves, and have a groove shape corresponding to the shape of the rails 14a and 14b. An appropriate configuration can be adopted without departing from the gist of the invention. The form of the rails 14a and 14b itself is not limited to a pipe shape, and may be a cylindrical or prismatic rod shape.

  Further, in the embodiment, the pedestal 2 and the tray mounting shelf 3 are movable in the axial direction of the axle 7, and the tray mounting shelf 3 is removable from the pedestal 2. However, in the present invention, the pedestal 2 has an axle. Needless to say, the present invention can also be applied to a cart in which 7 is fixed (impossible to move in the axial direction) and a cart in which the tray mounting shelf 3 is integrated with the base 2.

  The present invention is not limited to the use at the time of harvesting strawberry cultivated in the house, for example, at the time of harvesting various agricultural products such as tomato cultivated in the house or strawberry and tomato cultivated in the open field It can also be used during work.
