In addition, it is preferable that the seating portion is configured so as to be adjustable to move back and forth in the axial direction of the skeleton portion, so that the seating position in the skeleton portion can be appropriately adjusted. The function of only stabilizing the sitting posture of the person and the function of moving the seedling trolley with seat forward may be incorporated with a simple power source separately, and it may be replaced or used as an auxiliary. .

[0013] The seedling planting unit is disposed below and behind the above-mentioned skeleton, and mainly fulfills the function of grooving and the function of putting or covering soil on seedlings or seeds planted in the trench. Therefore, desirably, a function of leveling the surface of the ground in front of a part entering the groove cutting is also added, or a function of making the groove cutting depth constant in the groove cutting process, or conversely, It should be realized as having the function of preventing the floating from the ground surface, etc., and therefore, it has a leading plow blade for piercing a predetermined place, and furthermore, the seedling is penetrated vertically. It is equipped with a mouth and has a substantially ship-shaped groove-grooving section that provides a groove of a predetermined width over a predetermined depth range from the ground surface, and automatically gathers surrounding soil into the groove after planting seedlings And the porcelain board to fill up It must be formed in a structure having at least the grooving frame portion, and the earth approaching plate portion is directed rearward and downward from the left and right sides with a seedling planting gap at the upper rear end side. It is formed so as to form a pair of left and right wings that are inclined.

[0014] The seedling planting section is provided with a dirt corner protruding at an upper end portion thereof, and a surface portion which tends to stop on both sides in a groove formed by a groove cutting frame. In order to prevent the scattered soil mass from falling and entering, the soil on the front field surface at the position where the grooving is planned can be leveled before the grooving. Or, on both sides of the planting edge of the grooving frame portion, an eaves edge portion which is formed so as to extend substantially horizontally toward the outside or inclined upward toward the left and right outer sides is formed at a certain depth. Or the formation of a groove is ensured, or the grooved frame portion is pivotally mounted on the base end around the lower middle part of the skeleton, and the free end is directed rearward and downward with respect to the traveling direction. After inclining, a compression mechanism such as a compression spring is A very convenient one, such as one that is attached to the tip of a dragging arm rod part that can swing up and down, and that prevents the tendency of the grooved frame part to float from the ground surface, etc. can do.

The grooving frame is a main part of the above-described seedling planting apparatus, and has a function of cutting a groove having a width and depth sufficient for planting seedlings on the ground surface. It has a shape with a left and right side wall surface that is tapered at the front end and is approximately perpendicular to the rear side, soil is cut open at the front end side, and a groove of a predetermined width and depth is securely formed from the center to the rear side. On the other hand, the seedlings must be formed between the left and right side walls, and the seedlings for seeds or seeds are secured between them. It is also possible to add a configuration in which the size of the opening can be changed by expanding the planting opening.

The leading plow blade is a component attached to the grooving frame, and has a function of guiding the grooving frame toward the ground, and has a predetermined depth on the tip side of the grooving frame. At the position, it is formed as a metal plate that is inclined downward toward the front in the direction of travel and made of a metal plate in which the plane shape that becomes an acute angle toward the distal end becomes a substantially isosceles triangular shape. Or or, assuming that the frequency of use increases and breaks or deforms, so that it can be attached to the grooving frame part predetermined place with a structure that can be replaced as appropriate, or
In the event of a difference in bite resistance due to differences in soil, etc., it is possible to change the inclination angle to the optimal one and to form a structure that allows adjustment and adjustment. Thus, it is possible to add a variety of convenient structures.

The seedling planting opening is a portion functioning as a space for placing seedlings or seeds in the surface trench cut open by the grooving frame, and formed so as to penetrate vertically between the left and right wall surfaces of the grooving frame. The seedlings or seeds held by the worker must be opened to a size that allows them to safely and securely reach the bottom of the ditch. On the roots or seeds of the seedlings planted in the ditch, after collecting the soil from the left and right sides of the ditch and dropping it into the ditch, it functions to compact it properly with filling pressure, and to the root In order to ensure that the soil is buried securely, it is inclined downward toward the rear and inclined downward toward the outside in the left-right direction, and the size of the seedling gap at the rear end Should be as narrow as possible. In should be those to allow earthing up.

The soil dividing corners are used to equalize soil clumps and surface irregularities scattered on the surface of the field in advance, and to form a groove by the grooving frame portion, an extra portion above and behind the grooving frame portion. It has a function of preventing the soil from entering the seedling planting opening or the formed groove described above, and has a flat shape or a triangular pyramid shape in which the upper surface side is inclined forward. For example, it is formed into a shape having an appropriate shape that is convenient for sorting out the earth mass on the ground surface and leveling the uneven surface.

The drag arm rod portion functions as one means for connecting the seedling planting device to the skeleton portion. The seedling planting device is connected to the skeleton portion by a vertical arm rod portion or the like. It is one connecting means other than the case where it is configured to be fixedly attached at a predetermined lower position, and is directed backward in the traveling direction so as not to hinder movement of the seedling cart with seats. In addition to being attached as a fixed object fixed to the lower side at a predetermined angle, the upper end side is pivotally attached to the lower side of the skeleton part so that the grooved frame part can move up and down with respect to the ground. A weight having a predetermined weight is attached to a pressing mechanism portion, for example, a device utilizing an elastic component such as a spring such as a coil spring or a plate spring or rubber, or a midway portion of a groove cutting frame portion or a drag arm portion. The vertical movement is restricted to a predetermined range by incorporating a mechanism Or a parallel link mechanism built into the vicinity of the seedling opening where it does not cause an obstacle, so that the grooving frame always maintains a posture parallel to the ground surface when moving up and down. Or, it can be moved up and down, and can be temporarily fixed at a plurality of angular positions, provided with a temporary fixing mechanism, and depending on factors such as the type of seedling to be planted and the depth of the ridge, the surface depth of the grooving frame portion It may be configured such that the position can be appropriately changed.

The seedling stock section has a function of temporarily preparing a large number of seedlings within a range that can be easily reached by an operator who is seated backward on a seating planting cart with a seat. A mounting table or mounting frame for placing boxes such as a seedling box or a cell tray, a hanging frame for hanging a seedling box or the like so as to keep the seedling box horizontal, or for directly storing seedlings It can also be used as a seedling storage basket. When the seedling cart with a seat of the present invention is used for planting seeds, the seedling stock section is used as a portion for placing containers or the like accommodating the seeds.

The gripping rod portion functions as a grip for supporting the body of the seedling planter during the work, and also as a handle for gripping when moving the seated seedling cart. In addition to being fixed horizontally to one or the left or right of the middle part of the skeleton part, if possible, it is formed as a structure that allows the attachment position to be changed appropriately back and forth, and the left and right hand of the worker It is desirable to form it in a detachable structure that can be attached to the opposite side.

Embodiment 2 The side view of the seedling trolley with a seat having the disassembled structure shown in FIG. 6 and the case shown in the side view of the seedling trolley with a seat completed in FIG. This shows another embodiment included in the seedling cart, in which a detachable structure portion 11 for separating front and rear is provided at one point in the skeleton portion 1 so that it can be disassembled and assembled. .

The skeletal portion 1 is located near the back of the seating portion 3.
It is separated forward and backward at a position forward of the seedling planting unit 7, and is fitted to the rear end of the seating side skeleton 15 at the front end of the seedling supply side skeleton 16 behind it in a fitting manner. A tongue piece 12 is formed and a center of the tongue piece 12 is formed.
In addition, a through-hole that is concentrically arranged when connected to each other is formed in both the front end of the seedling supply-side skeleton portion 16 and a nut portion 13 is fixed to the outside of the through-hole of the seedling supply-side skeleton portion 16. Then, the seedling supply side skeleton 16 is seated on the front end of the seedling supply side skeleton 16.
5 After the tongue piece 12 at the rear end is attached and connected, a bolt 14 is inserted into both through holes, and the seat side skeleton 15 and the seedling supply side skeleton 16 are connected by turning and screwing. It is assumed that an attachment / detachment structure 11 that can be formed as an integrated skeleton 1 is formed.

It can be used independently as a working truck with seats or a transporting truck having four wheels, 21 and 21 for field use and auxiliary wheels 17 and 17 for field use, for planting seedlings with seeds in seedling planting work. Outside of use as a trolley,
A configuration that can be used for various operations in a normal operation is incorporated in advance.

[0030]

[Operation] The seedling trolley with a seat according to the present invention having the above-described configuration is arranged along the furrow as shown in the side view of the seedling planting operation in FIG. After placing a seedling box 51 accommodating a large number of green onion seedlings 9, 9,..., The operator sits on the seating section 3 in a rearward posture, and moves in the rearward direction of the worker with the posture as it is. Puts force by stretching the legs, and performs the operation of moving the back side with the buttocks attached to the seating part 3, and furthermore, if necessary, removes the gripping rod 4 and the skeletal part 1 with the free hand. Grasp and move the seated seedling trolley little by little (that is, by a distance approximately equivalent to the seedling spacing) while allowing the force from the feet to be effectively transmitted to portions other than the seating portion 3. I do.

In the course of the forward movement of the seating seedling cart with the seat due to the movement of the worker's own feet, the seedling planting unit 7 which projects downward and toward the rear of the skeleton 1 is formed by the coil spring 82 of the pressing mechanism 8. Receiving a predetermined downward pressure due to the stability of
It is inserted to a predetermined depth in the soil so that the leading plow blade 73 is guided from the ground surface, and enters the ground to a depth where the soil dividing corner 76 and the eaves edge 75 abut the ground surface, and is a plane ship-shaped grooving. The frame 71 moves forward to form a groove for planting seedlings below the planting opening 72. At this time, the soil dividing corner portion 76 smooths out the uneven surface of the ground immediately before the groove formation portion and removes the obstructive soil mass, etc., and inadvertently inserts the soil or the earth mass into the groove formed by the grooving frame portion 71. Etc. are prevented from falling.

Each time the seedlings move forward, the leek seedlings 9 taken out of the seedling box 51 mounted on the seedling stock part 5 are placed in a planting groove formed below the seedling opening 72 of the seedling planting part 7. Grasp the lower side and insert the hand into the seedling opening 72 so as to place the plant. With the green onion seedling in the standing position, the worker kicks the ground with his feet and stretches. Advancing the seedling trolley with seat,
After moving a suitable distance, the same operation is performed again to plant the green onion seedlings 9, and thereafter, the same process is repeated.

The leek seedling 9 is placed in the groove as described above,
When moving forward again, the left and right mulling plates 74, 74 following the seedling planting opening 72 incorporated in the seedling planting unit 7 pass the left and right of the green onion seedling 9 while gathering the soil that has been sliced to the left and right. Acts to form a ridge around and, when further advanced, guide frames 23, 23 that follow guide the implanted green onion seedling 9 so as to be sandwiched from the left and right, and the left and right positioned rearward in the traveling direction. A pair of upland wheels 22, 2
The green onion seedlings 9 are led to the rear wheel 2
It is possible to pass on both sides of the leek seedling 9 without being caught by the onion seedlings 2 and 22, and in the process of passing, the rear side field wheels 22 and 22 have an inclined structure in which the lower side faces inward. Since the installation surfaces are configured so as to form a "C-shaped" frontal shape, they act to compact the ridge-shaped soil at the base of the green onion seedling 9 from the left and right, and the groove between the ridges is formed. Leek planting work is being carried out in which leek seedlings are reliably planted.

The pressing mechanism 8 incorporated in the dragging arm 6 presses the seedling planting device 7 against the seedling planting area on the surface of the field with a predetermined pressure. In combination with the rim 75, the grooving frame 71 acts so as to remain in the ground at a predetermined depth, and in some cases, faces a hard object such as a stone in the ground. When a resistance force is received, the free end side of the drag arm 6 (the end on which the seedling planting unit 7 is mounted) rises due to the contraction of the coil spring 82 of the pressing mechanism 8 and becomes excessively large. Thus, the entire seedling planting unit 7 moves forward while avoiding such foreign matters, and functions particularly to prevent deformation and breakage of the leading plow blade 73 and the like.

Also, a seedling with a seat configured as shown in the side view of the dolly with a seat having the disassembled structure of FIG. 6 and the dolly with a seat completed assembling in FIG. The planting trolley inserts the tongue piece 12 of the seating-side skeleton 15 into the traveling direction end of the seedling supply-side skeleton 16, inserts the bolt 14 into the through hole, and screws it into the nut 13. By constructing the framework 1 of the seedling-bearing cart with a screw, by unscrewing the bolt 14, pulling out the through-hole, and removing the tongue piece 12 from the end of the seedling supply-side framework 16 in the traveling direction, The skeletal portion 1 that has been formed into a single skeleton can be decomposed into a skeletal portion 15 on the seating side and a skeletal portion 16 on the seedling supply side.

The trolley for seedling planting with seats of this embodiment is arranged on the wheels 21 and 21 for field and the auxiliary wheels 17 and 17 for field arranged on the frame 15 on the seating side and on the frame 16 on the seedling supply side. The total of six wheels including the field wheels 22 and 22 is the skeleton 1
3 is supported at each of the front and rear portions and a portion slightly behind the seating portion 3, and the skeletal portion 1 includes the weight of the worker on the seating portion 3 and the load of the seedling 9 from the seedling stock portion 5.
This realizes a structure that can disperse the load that must be supported and at the same time prevent a large load from being applied to the detachable structure 11.

On the side of the seat-side skeleton 15 disassembled from the seedling supply-side skeleton 16, the four wheels of the field wheels 21 and 21 and the field auxiliary wheels 17 and 17 remain. Can be moved freely back and forth while the worker is seated, and a stool for various operations other than seedling planting such as sowing, weeding, and harvesting. Although not shown, an auxiliary pallet or the like may be appropriately mounted on the seating portion 3 or the seating portion 3 itself may be detached and a tray member may be appropriately mounted to be used as a transport trolley. It is made possible.

Although the leek planting cart with seat according to the present invention uses leek planting as a typical example of use in the description of the illustrated embodiments and the like, it is a matter of course that the invention is not limited to this application. Also, it is not intended to be used by arranging it between furrows, and is not limited to seedling planting as the name of the invention, for example, sowing seeds of green soybeans and seeds of various vegetables It is also possible to use for sowing, or for planting seeds or sowing seeds on flat ground, etc. Naturally, each part structure that must be modified or added according to their use is naturally included in the present invention. It goes without saying that it will be something.

[0039]

[Effects] As described above, according to the seedling cart with a seat of the present invention, it is necessary to move the seat while sitting on the cart, remove the seedlings from the loaded seedling stock section, plant the seedlings as they are, and perform any other operations. It is possible to carry out a series of seedling planting work such as transporting seedlings, digging the field, and bringing soil to the planted seedlings without trouble. Kneeling, the seedling planting work, which had been a heavy burden due to the manual work in the forward bending posture, can be greatly reduced and made more efficient,
Therefore, there is no need to secure a large number of workers or introduce a large and expensive dedicated seedling planting machine, which has the excellent feature of greatly improving work content and reducing cultivation costs. Will be.

At the time when there is no seedling planting operation, it is possible to use as a stool that can be moved while sitting only on the side of the seating side skeletal portion 15 separately. The field wheels 17, 17 are provided in the vicinity of the detachable structure 11 of the side skeleton 15 to form a six-wheel structure, so that the strength of the members required for the skeleton 1 is reduced, and it is possible to commercialize the frame as thin as possible. , That At the same time only inexpensive to be provided, the cost of transportation as a commercial product can also be reduced, and more so that a large advantage of those favorable from handling operability as the instrument is obtained.

As described above, the seedling-planting trolley with seat of the present invention can achieve the intended purpose uniformly by its novel structure, is easy to manufacture, and has been used by many people for many years. Compared to manual work without the use of seedlings or seedling planting using a dedicated machine for expensive seedlings, it can be much more economical, and the work efficiency itself can be increased, so that cost reduction and It is possible to shorten the seedling planting period and reduce the work content without fail. It is highly evaluated not only by farmers of various vegetables but also by farm equipment manufacturers, and is widely adopted and popularized. It is expected to do.
