  However, the above-described flower cart has a problem when the fresh flowers to be harvested from the flower field are tall, such as gypsophila, statice or eustoma. In other words, fresh flowers as described above are often in a state where the upper part of the flower falls between the ridges and leans between the ridges at the time of harvest. For this reason, when moving the flower trolley, the parts that are leaning between the fresh flowers are touched by the upper parts of the left and right side frames of the flower trolley that is moving and moved, causing damage and breakage. , There will be a loss of commercial value. Also, when loading fresh flowers cut out from one bud onto a flower trolley, it may fold this against the unharvested fresh flowers that are leaning or leaning toward the top of the flower trolley from the other heel, I will lose the value of the product. If you want to eliminate such problems, work to push the flower carriage from behind and move it so that the flower carriage moving and moving on the front of the flower carriage does not hit It is necessary to work together with the person, and the human cost is high.

  The present invention has been made in view of the above-described conventional problems, and reliably prevents a fresh flower from being damaged or broken even by only one operator while having a simple and inexpensive configuration. An object of the present invention is to provide a flower-collecting cart that can efficiently harvest fresh flowers.

In order to achieve the above object, a flowering cart according to the first aspect of the present invention comprises a left and right support bar horizontally opposed in parallel at a distance corresponding to two adjacent ridges, and pushes on each rear end portion. Left and right side frame structures that are provided with operating handle portions for moving and rotating operation and fixed to the left and right support bars so as to rotate integrally with the left and right support bars ; Both end portions of a rectangular metal flat plate spanned between the support rods are curved in a substantially circular cross section, and a holding portion is provided to hold the left and right support rods in a freely rotating manner. A plurality of bottom beam members that form a chassis together with the support rods, wheels that are rotatably attached to a lower surface portion of a bottom beam member at least on the front side in the traveling direction of the chassis, and the left and right wheels the operation Han each end is fixed to an end portion of the support rod The support rods are provided so as to rotate together with the support rods with the support rods as fulcrums in conjunction with the operation of the support portions, and the other end portions of the support rods move between two stop points according to the rotation of the support rods. A pivot range restricting structure coupled in a displaceable state , wherein the pivot range restricting structure causes the left and right side frame structures to be separated from each other and close to each other with the left and right support bars as fulcrums. The rotation range when rotating in the direction is restricted, and it is possible to select whether or not the side frame structure contacts the fresh flowers at the time of flowering .

The flowering / carriage trolley of the invention according to claim 2 is the flowering / carriage trolley according to claim 1, wherein the rotation range restricting structure in which each end is fixed to the left and right support bars so as to be integrally rotatable. A belt-like engagement piece formed by cutting and raising each of the left and right elastic parts formed by two right and left pipes and the other end of each of the left and right pipes being crushed into a flat shape; An engagement hole formed by a notch for forming a combined piece, wherein the left and right elastic parts are overlapped with each other, and the left and right engagement pieces are engaged with engagement holes of the different elastic parts. The elastic portions are elastically deformed by receiving a pulling force or a pressing force when the support rods are rotated, and the engagement pieces move in the engagement holes so that the elastic portions overlap. The mating portion is configured to be displaced in an expanded / contracted state .

  According to a third aspect of the present invention, there is provided the flowering / carriage trolley in the flowering / carriage trolley according to the first or second aspect, wherein the holding portion rotates in a state where both left and right support rods are passed through both end portions of the metal flat plate. It is bent into a cylindrical shape that can be freely held and is integrally formed with the bottom beam member.

  According to a fourth aspect of the present invention, there is provided the flowering / transporting carriage according to the second aspect, wherein the engagement piece is in contact with an arbitrary position of the engaging hole in the rotation range regulating structure. By freely attaching, a band body for arbitrarily setting the rotation range of the rotation range restricting structure is provided.

The flowering / carriage trolley of the invention according to claim 5 is the flowering / carriage trolley according to claim 2 or 4,
Each of the left and right pipes is bent, and the support rod, the side frame structure, and the rotation range regulating structure are integrally formed.

According to the flower transportation cart according to claim 1, when the flower transportation cart is moved forward, if the left and right side frame structures are operated in the closing direction, the left and right side frame structures are turned within a rotation range restricting structure. The body is stably held in an inwardly closed state at a predetermined angle. In this state, by moving and moving the flower-collecting carriage, even if the fresh flowers planted in the cocoon are tall and inclined from the heel to the heel, the side frame structure is Since it is inclined in the inward closing direction, it can move forward without contacting the fresh flowers, so that there is no problem of damaging or breaking the fresh flowers. When the harvesting operation for cutting the fresh flowers of the camellia is performed, the left and right side frame structures are rotated so as to open outward. Thereby, the left and right side frame structures are stably held in a state where they are opened outward at a predetermined angle by the rotation range regulating structure. When the left and right side frame structures are rotated in a direction to open outward, the tall fresh flowers that are inclined from the heel to the heel are lifted upright on the heel. As a result, the upper part of the chassis is pushed back to the outside, and the left and right side frame structures are widely opened, so that the work of stacking fresh flowers cut from the basket on the chassis is an obstacle. It can be done easily by not having anything. In addition, there is no possibility that the fresh flowers that are inclined above the chassis will be damaged or broken when the cut flowers are stacked on the chassis as in the prior art.

  According to the flower transportation cart according to claim 2, the rotation range regulating structure is configured by a pipe, and the pipe is processed and configured as defined in claim 2, so that the structure is surely simple. A rotation range regulating structure that fulfills that role can be realized.

  According to the flower transportation cart according to claim 3, the left and right support bars can be rotatably held by the holding part integrally formed with the bottom beam member, so that the chassis can be configured, and therefore the support bar is rotated using a bearing or the like. Compared to a structure that can be freely held, the cost is further reduced.

  According to the flowering and transporting carriage according to claim 4, the band piece can be detachably attached to an arbitrary position of the engagement hole in the rotation range regulating structure, whereby the engagement piece can be attached to the band body at an arbitrary position. Since the rotation range of the left and right side frame structures can be arbitrarily set by abutting, the rotation range of the left and right side frame structures can be set according to the difference in the spacing between the buds and the height of the planted flower F It can be arbitrarily variably set corresponding to the difference in height.

According to the flowering and transporting carriage according to claim 5, the left and right support bars, the side frame structure, and the rotation range regulating structure are integrally formed by bending one pipe, thereby simplifying the configuration. Accordingly, further cost reduction can be achieved.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a flower transportation cart according to a first embodiment of the present invention. In this flower-carrying carriage, two bottom beam members 4 and 5 made of a rectangular metal plate are bridged between left and right support bars 2 and 3 horizontally and horizontally arranged to form a carriage 1. The left and right wheels 10 and 11 are rotatably attached to the lower surface portion of the bottom crosspiece member 4 on the front side (front side in the drawing) of the chassis 1. In this embodiment, aluminum pipes are used as the support bars 2 and 3, and aluminum flat plates are used as metal flat plates for forming the bottom beam members 4 and 5, thereby reducing the weight. The support rods 2 and 3 made of aluminum pipes are closed at both ends by covering the plugs 8 and horizontally and parallelly arranged at intervals corresponding to two adjacent ridges of the flower garden.

FIG. 2A shows a longitudinal sectional view of the bottom beam member 4 on the front side in the traveling direction (front side in FIG. 1) of the flowering carriage, and the bottom beam member 4 is hung on the left and right support rods 2 and 3. The two ends of the rectangular aluminum plate passed are curved to form a cylindrical shape having an inner diameter slightly larger than the outer diameter of the support rods 2 and 3, and two sheets are stacked in a state of forming the cylindrical shape. 4 are fixed to each other with bolts 12 so that the left and right support rods 2 and 3 pass through and are held together so as to be rotatable. ing. Further, the inner side portion of the bottom beam member 4 with respect to the fixing portion by the bolt 12 is bent downward to form the outer mounting arms 13 of the wheels 10 and 11. In addition, an auxiliary member 14 in which left and right inner mounting arms 15 of the wheels 10 and 11 are formed by folding both sides of an aluminum flat plate is superimposed on the lower surface of the bottom beam member 4 at the center of the lower surface of the bottom beam member 4. In this arrangement, it is fixed by four bolts 12 at the front and rear. The left and right wheels 10 and 11 are disposed between the outer mounting arm 13 and the inner mounting arm 15 and are rotatably supported by a support shaft 18. In this embodiment, the left and right wheels 10, 11 are inclined downward by a slight angle (about 2 to 3 °) in an outwardly opened state, and are supported on the outer mounting arm 13 and the inner mounting arm 15 by the support shaft 18. It is supported.

  FIG. 2B shows a side view of the bottom beam member 4, and the holding portions 9 on both the left and right sides of the bottom beam member 4 are crushed in the vicinity of the front and rear ends of the holding portion 9 in the support rods 2 and 3, respectively. The four positioning protrusions 19 bulging slightly outward from the outer peripheral surfaces of the support bars 2 and 3 are prevented from moving in the front-rear direction along the support bars 2 and 3. The positioning projection 19 is formed in a shape and a position where a large frictional resistance is not generated between the support rods 2 and 3 and the holding portion 9 when the support rods 2 and 3 are rotated. In FIG. 1, the illustration of the positioning protrusion 19 is omitted for the sake of convenience to prevent the drawing from becoming complicated and difficult to understand. The bottom beam member 4 is formed by using a rectangular flat plate having a width sufficiently larger than a plurality of strip-shaped horizontal beams provided on the existing flower carriage. It has a sufficient length L (corresponding to the width of the holding portion 9) corresponding to the large width of the crosspiece member 4. The length L of the holding portion 9 is preferably set slightly larger than the outer diameter of the wheels 10 and 11. The effect of this will be described later. Further, through holes 20 are formed in the outer and inner mounting arms 13 and 15, and the work for dropping the soil attached to the wheels 10 and 11 can be easily performed by the through holes 20. Further, as shown in FIG. 2 (b), at the rear position of the outer pick arm 13 and the inner pick arm 15 in the traveling direction of the carriage, a soil drop piece 16 suspended from a position close to the wheels 10 and 11 is provided. In addition, when moving forward during work, soil mud and dust adhering to the rotating wheels 10 and 11 are stripped off by the soil dropping pieces 16.

  FIG. 3 is a longitudinal sectional view of the bottom crosspiece member 5 on the rear side in the traveling direction of the flower transportation cart shown in FIG. Also in this bottom crosspiece member 5, as in the case of the front bottom crosspiece member 4 described with reference to FIG. 2, both end portions of a rectangular aluminum flat plate spanned on the support rods 2 and 3 are connected to the support rods 2 and 3. Four bolts 12 (see FIG. 1) at the front, rear, left and right of the portion that is curved so as to form a cylindrical shape having an inner diameter slightly larger than the outer diameter, and in which the cylindrical shape is formed are overlapped. By fixing them to each other, a holding portion 21 that penetrates the left and right support rods 2 and 3 and holds them rotatably is integrally formed. Although not shown in the holding portion 21, as in the holding portion 9 of the bottom beam member 4, the supporting rods 2 and 3 are crushed in the vicinity of the front and rear ends of the holding portion 21, respectively. , 3 are prevented from moving in the front-rear direction along the support rods 2 and 3 by the four positioning projections bulging outward slightly from the outer peripheral surface.

Returning to FIG. 1, left and right side frame structures 22 and 23 are fixedly erected on the left and right support rods 2 and 3 so as to rotate integrally. The left and right side frame structures 22, 23 have the same structure, and both ends of an outer frame body 24 in which both side portions of the aluminum pipe are bent at right angles are fixedly attached to the support rods 2, 3. Has been. In this outer frame 24, horizontal bars 25 made of aluminum strip-shaped flat plates are horizontally arranged across the front and rear frame portions of the outer frame body 24, and both ends are fixed by bolts 28, A vertical beam 29 made of an aluminum belt-like flat plate similar to the beam 25 is fixed vertically with bolts 28 in a vertical arrangement that spans the horizontal upper frame of the outer frame 24 and the support rods 2 and 3. ing. The left and right side frame structures 22,
23 is fixed to the support rods 2 and 3 rotatably supported by the bottom beam members 4 and 5, so that it is inclined in the horizontal direction of the chassis 1 together with the bottom beam members 4 and 5. It is provided so that rotation is possible. An operating handle 30 is integrally formed at the rear end portion of each of the left and right outer frame bodies 24 so that the upper end portion bulges backward in a curved shape. This is used both for pushing and for rotating the left and right side frame structures 22 and 23.

  Between the rear end portions of the left and right support rods 2 and 3 in the traveling direction of the respective chassis 1, the operator holds the operation handle 30 so that the left and right side frame structures 22 and 23 are outward with respect to the chassis 1. A rotation range restricting structure 31 is provided that restricts the turning range when the turning operation is performed in the opening direction or in the direction of inclining toward the inside of the chassis 1 and approaching each other. In FIG. 1, for convenience of illustration, the rotation range restriction structure 31 is schematically shown, and the rotation range restriction structure 31 will be described in detail with reference to FIGS. 4 and 5.

  FIGS. 4A and 4B are a plan view and a front view showing a schematic configuration of the rotation range restricting structure 31 when the left and right side frame structures 22 and 23 are inclined inward, respectively. 5 (a) and 5 (b) show schematic configurations of the rotation range restricting structure 31 when the left and right side frame structures 22 and 23 are inclined to be opened toward the outside of the chassis 1, respectively. It is the top view and front view which show. The rotation range restricting structure 31 is composed of left and right aluminum pipes each having one end fixed in a relative arrangement that hangs downward with respect to the left and right support rods 2 and 3. In this embodiment, a flower-carrying cart with a short vehicle body length in which left and right wheels 10 and 11 are provided only on the lower surface of the bottom beam member 4 on the front side in the traveling direction of the chassis 1 is illustrated. Therefore, the rotation range regulation structure 31 includes left and right support legs 32 and 33 for supporting the chassis 1 together with the left and right wheels 10 and 11 in a horizontal state to the support rods 2 and 3 in the left and right pipes. An intermediate portion in the vicinity of the fixed portion is formed in an arc shape. When the support legs 32 and 33 are rotated in any direction, their lower ends are in contact with the ground and support the chassis 1 together with the left and right wheels 10 and 11 horizontally.

  The rotation range regulating structure 31 is configured by connecting the distal ends of the left and right pipes in an engaged state, and is operated to open or close the left and right side frame structures 22 and 23. When the left and right support rods 2 and 3 are rotated in different directions as indicated by arrows in FIGS. 4B and 5B, the two support rods 2 and 3 shown in FIGS. It functions so as to restrict the rotation range between the rotation stop positions. As shown in FIGS. 4 (b) and 5 (b), the left and right pipes, which are constituent materials of the rotation range regulating structure 31, are elastically deformed by being crushed into flat plate shapes at their respective tip portions. A portion 17 is formed, and both elastic portions 17 have the same configuration. That is, both elastic portions 17 and 17 are cut to form band-like engagement pieces 34 and 34 formed by cutting and raising them in a direction perpendicular to the cut and engagement pieces 34 and 34. The engagement holes 35 and 35 formed by the above are provided. Each of the engagement pieces 34 and 34 is bent in an orthogonal direction toward the elastic portion 17 different from itself, and is inserted into the engagement holes 35 and 35 of another elastic portion 17. Further, the engaging pieces 34 and 34 are formed with guide portions 38 and 38 that are prevented from coming off at right angles after being led out from the engaging holes 35 and 35 at a right angle.

The rotation range regulating structure 31 is engaged so that the left and right engaging pieces 34, 34 can be displaced along the respective engaging holes 35 by elastic deformation of the elastic portion 17. 17 is connected to extend and contract, thereby allowing the left and right support rods 2 and 3 to rotate within a set rotation range. That is, as shown in FIG. 4, when the left and right side frame structures 22 and 23 are tilted inwardly and rotated in the closing direction, the engagement pieces 34 and 34 of the left and right pipes are brought into contact with each other. The rotation of the support rods 2 and 3 is stopped when contacted. At this time, since the left and right side frame structures 22 and 23 rotate with the lower support rods 2 and 3 as fulcrums, the center of gravity of the side frame structures 22 and 23 is higher than the support rods 2 and 3. It is in the upper position. For this reason, the side frame structures 22 and 23 that are turned in an inwardly tilting direction extend inwardly beyond the vertical line passing through the center of the support rods 2 and 3 indicated by the one-dot chain line in FIG. When turning to a position that inclines inward, as shown by the arrow, inward turning force is generated with the support rods 2 and 3 as fulcrums by its own weight. Accordingly, the left and right side frame structures 22 and 23 are stably held in a closed state by a rotation range restricting structure 31 having a simple configuration that does not include a mechanism for generating a braking force for stopping the rotation. .

  On the other hand, as shown in FIG. 5, when the left and right side frame structures 22, 23 are tilted outward and rotated in a direction to open each other, the engagement pieces 34, 34 of the left and right pipes are The rotation of the support rods 2 and 3 is stopped at the point of contact with the hole ends of the engagement holes 35 and 35. Also in this case, the side frame structures 22 and 23 that are turned in a direction inclined outwardly are vertical lines passing through the centers of the support rods 2 and 3, as indicated by a one-dot chain line in FIG. When it is located in a state where it is inclined outward beyond the distance, the turning force to the outside is generated with the support rods 2 and 3 as fulcrums due to its own weight. As a result, the left and right side frame structures 22 and 23 are stably held in an open state by a rotation range restricting structure 31 having a simple configuration that does not include a mechanism for generating a braking force for stopping the rotation. . Further, the left and right side frame structures 22 and 23 are restricted in rotation within a rotation range between a closed state and an open state, with the left and right support rods 2 and 3 having their lower ends fixed as fulcrums, respectively. On the other hand, the rotation range restricting structure 31 is provided in an arrangement for restricting the rotation range in the vicinity of the left and right support rods 2 and 3. Therefore, the displacement range of the rotation range restricting structure 31 is extremely small as compared with the rotation ranges of the left and right side frame structures 22 and 23, for example, about 3 cm. Therefore, as shown in FIGS. It operates smoothly while producing a certain degree of bending while having a simple structure integrally formed with the left and right pipes.

  Next, the flower transport operation using the flower transport cart of this embodiment will be described in detail with reference to FIGS. Prior to performing the flower transportation operation, a flower transportation carriage is brought between two adjacent ridges 39, 39 in the flower field, and the flower net 40 is put on the left and right side frame structures 22, 23 from the chassis 1. Then, when the flower-carrying cart is advanced, the left and right operation handles 30, 30 are operated in the direction in which the left and right side frame structures 22, 23 are closed, as shown in FIG. Accordingly, as described with reference to FIG. 4, the left and right side frame structures 22 and 23 are stably held in a state where they are closed inward at a predetermined angle by the rotation range regulating structure 31. Subsequently, the left and right operation handles 30 are gripped, and the flowering cart is advanced while keeping the cart lifted until the support legs 32 and 33 formed on the rotation range regulating structure 31 are separated from the ground. Move. At this time, the side frame structures 22 and 23 are closed inward even when the fresh flowers F planted in the ridge 39 are tall and are inclined from the ridge 39 toward the ridge. Since it can be moved without coming into contact with the fresh flower F, there is no problem that the fresh flower F is damaged or broken.

  Further, when performing the harvesting operation of cutting the fresh flowers of the culm 39, as shown in FIG. 7, the left and right operation handles 30, 30 are grasped to open the left and right side frame structures 22, 23 outward. To rotate. As a result, as described with reference to FIG. 5, the left and right side frame structures 22 and 23 are stably held in a state of being closed outward at a predetermined angle by the rotation range restricting structure 31. When the left and right side frame structures 22 and 23 are rotated in the direction of opening outward, the left and right side frame structures 22 and 23 are lifted so as to raise a tall fresh flower F that is inclined from the heel 39 toward the ridge. Let it stand upright. Thereby, since the fresh flower F is pushed back outward and the left and right side frame structures 22 and 23 are widely opened above the chassis 1, the fresh flower F cut from the ridge 39 is placed on the flower net on the chassis 1. The work stacked on 40 can be easily performed because there is no obstacle. Further, when the fresh flowers F cut out in the conventional manner are stacked on the chassis 1, there is no possibility that the fresh flowers inclined above the chassis will be damaged or broken.

In addition, even if the left and right side frame structures 22 and 23 are opened outwardly, the flower-carrying carts as shown in FIG. Since 11 is attached in an arrangement in which the lower part is inclined outwardly, a stable state without fear of falling can be maintained. Further, since the support rods 2 and 3 support the left and right side frame structures 22 and 23 so as to be rotatable only for the purpose of rotating within a predetermined rotation range, the bottoms can be used without using bearings or the like. The both ends of the crosspiece member 4 can be held without hindrance by the holding portion 9 formed by bending in a cylindrical shape, and the configuration can be further simplified.

  Further, as shown by a two-dot chain line in FIG. 4A, the screwing band body 36 is detachably attached to an arbitrary position of the engagement hole 35 in the elastic portion 17 of the rotation range regulating structure 31. For example, the rotation range of the left and right side frame structures 22 and 23 can be arbitrarily set by bringing the engagement piece 34 into contact with the screwing band body 36 at an arbitrary position. Thereby, the rotation range of the left and right side frame structures 22 and 23 can be arbitrarily variably set corresponding to the difference in the spacing of the ridges 39, the difference in the height of the planted fresh flowers F, and the like.

  FIG. 8 shows a modification of the first embodiment, which includes left and right support frame structures 26 and 27 formed by bending one pipe. The left and right support frame structures 26 and 27 include substantially inverted U-shaped outer frame portions 26a and 27a having operation handles 26b and 27b formed at rear end portions in the traveling direction, and front ends of the outer frame portions 26a and 27a. The support bar portions 26c and 27c extending horizontally from the inner portion and the rotation range restricting configuration portions 26d and 27d extending inward from the rear end portions of the outer frame portions 26a and 27a bend one aluminum pipe. It is integrally formed by processing. The left and right support frame structures 26 and 27 span the bottom beam members 4 and 5 similar to those of the first embodiment over the support bar portions 26c and 27c and hold the support bar portions 26c and 27c in a freely rotatable manner. With this configuration, a flowering / transporting carriage having substantially the same function as the flowering / transporting carriage shown in FIG. 1 can be manufactured at low cost.

  FIG. 9 is a side view showing a flower transportation cart according to the second embodiment of the present invention. In FIG. To do. This flower-carrying carriage is of a type that is longer in the traveling direction than that of the first embodiment, and a holding portion 9 for attaching the left and right wheels 41 is also formed on the bottom beam member 5 on the rear side. Has been. The rotation range restricting structure 42 provided on the flower-carrying trolley has a wheel 41 at the rear portion, so that it is not necessary to provide the support legs 32 and 33 as in the first embodiment, and has a simple configuration. It can be.

  That is, as shown in FIG. 10, the rotation range restricting structure 42 includes a rotation restricting pin 45 and the action piece 44 fixed to the left and right support bars 2 and 3 and the turn restricting pin 45 slide. An arcuate rotation restricting hole 48 is formed, and a restricting plate 49 fixed to the bottom crosspiece member 5 is provided. As shown in FIGS. 10A and 10B, the left and right action pieces 44 that rotate integrally with the support rods 2 and 3 as the left and right side frame structures 22 and 23 rotate are rotated. The movement restricting pin 45 is restricted so as to turn within a turning range in contact with the hole ends at both ends of the turning restricting hole 48. Therefore, also in this flower-carrying trolley, it is possible to obtain substantially the same operational effects as those of the first embodiment while the rotation range restricting structure 42 has a simple configuration.

  The present invention is not limited to the contents shown in the above embodiment, and various additions, modifications, or deletions are possible within the scope not departing from the gist of the present invention. It is included within the scope of the present invention.

  The bogie for transporting flowers of the present invention can efficiently cut and harvest fresh flowers planted in a flower field, and in particular, when harvesting tall fresh flowers, it may damage or break the fresh flowers.
