[Industrial applications]

 TECHNICAL FIELD The present invention relates to a work vehicle for an operator to board a hill and travel between ridges to perform strawberry harvesting and other cultivation management operations.

[0002]

[Prior art]

 At a strawberry farm, when the harvest season is over, the whole family goes out every day, holding a harvest box with one hand every day in a ridge with a width of about 1 m, and leaning forward by 90 degrees or more to check the maturity. I have to work. This work puts a heavy strain on the lower back, and even if a strong person continues to work for a long time, fatigue will increase, and most people suffer from severe back pain. In recent years, this work has been shunned by young people, aging has progressed, and even some people have stopped strawberry cultivation. As a solution to this problem, work vehicles that require electricity or an engine as a power source have been provided so far, but it is difficult to cross the ridge due to the heavy weight of the machine, and it is difficult for hand-picking work. It has not come into widespread use because it requires neither speed of progress nor weight. Therefore, the present inventor has previously proposed a strawberry passenger management work vehicle (Japanese Patent Application No. 63-120666). In this work vehicle, the heights of the back-tilt chair and the running pedal are almost the same, and the posture is such that the work vehicle lays upwards, making it difficult to work.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and is released from work in a forward bending posture during harvesting and hand-picking work and management work, and from an unnatural posture lying on his back in a passenger management work vehicle. It is intended to provide a work vehicle that can perform forward traveling operation and strawberry management work in a comfortable posture, and that travels in a ridge with side wheels that does not require carrying a harvest box.

[0004]

In order to solve the above problems, the strawberry passenger work vehicle of the present invention has a front wheel 3 provided with a handle 17 in front of a body frame 2 and a rear wheel 4 behind. The seat chair 5 is provided in the middle rear part of them, and the swing pedal 6 is provided in front of the seat chair 5 and at a position lower than this. Further, the rear wheel 4 is equipped with a traveling direction starting sprocket 7, and one end of a chain layer 16 hung on the starting sprocket 7 is fixed to the vehicle body frame 2 via a spring 15 and the other. The traveling vehicle body 1 is constructed by connecting the end to the tip of the conductive wire 9 connected to the pedal 6. Side wheels 10 are attached to one side of the traveling vehicle body 1 by side connecting rods 11 and 12 at predetermined intervals, and a harvest box mounting frame 14 is traveled on the side connecting rods 11 and 12 from the vehicle body 1 in a predetermined manner. It is provided at intervals.

[0005]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The traveling vehicle body 1 uses an aluminum vehicle body frame 2 to reduce the weight. A front wheel 3 equipped with a handle 17 is attached to the front of the vehicle body frame 2, and a rear wheel 4 is attached to the rear of the frame 2, and a seat chair 5 is provided in the middle rear portion between the front wheel 3 and the rear wheel 4. The seat 5 is attached so that the spine is almost vertical when sitting. Further, a pitch is provided from the seat 5 immediately behind the front wheel 3 and a swing pedal 6 is provided on the vehicle body frame 2 such that the seat 5 is mounted at a low position.

The swing pedal 6 has a T-shape with an upper end being a foot 6b, and a pivot pedal portion 6c of the pedal arm 6a is pivotally attached to a swing pedal bearing portion 18 extending below the vehicle body frame 2. . A wire fixing portion 6d is provided in the middle of the pedal arm 6a. Further, a footrest plate 19 having a width capable of placing both feet on the vehicle body frame 2 is penetrated and fixed so that the pedal arm 6a can be operated back and forth. When the position of the swing pedal 6 is high, when a person gets on the seat, he or she has an unnatural posture lying on his back, which makes it difficult to work. Therefore, it is necessary to install the swing pedal 6 in the lowest possible position. With a bicycle with a rotating pedal, it was not possible to lower the pedal position because there were obstacles such as hitting the furrow and damaging the seedlings and fruit by contact with strawberries, even if the pedal position was set low. Therefore, by adopting the forward drive system with the push pedal 6 and the traveling direction sprocket 7, the pedal width can be narrowed and the position can be lowered, and in addition, it is possible to run on one leg.

A traveling direction starting sprocket 7 that works in only one direction and idles in the other direction is attached to the rear wheel 4. One end 15a of the spring 15 is locked to the vehicle body frame 2 in front of the start sprocket 7, the other end 15b is directed toward the start sprocket 7, and the start sprocket 7 is wound around the other end 15b halfway. The proximal end 16a of the chain layer 16 is connected and its forward end 16b is connected to the conducting wire-9. The conductive wire 9 is fixed to the wire fixing portion 6d of the swing pedal 6. The conductive wire 9 may be directly fixed to the swing pedal 6, or may be guided by providing a wire guide pulley 8 in the middle. Further, since it is sufficient for the above-mentioned swing pedal 6 to have a function of pulling the conductive wire 9 forward by pushing with the foot, the fulcrum position of the swing pedal 6 and the mounting position of the conductive wire 9 are those shown in the figure. Other than that, there are various modes such as providing a fulcrum position on the upper body frame 2 (not shown).

The traveling vehicle body 1 is connected with front and rear side connecting rods 11 and 12, and side wheels 10 are attached to one side over the ridges at intervals. This width should be equal to the width of the strawberry ridge between about 1 m. The side connecting rods 11 and 12 can be expanded and contracted as an expandable double tube according to the width of the ridge (not shown). A support rod 13 or a support frame 14 for mounting the harvest box B on the side connecting rods 11 and 12 is provided between the side connecting rods 11 and 12 so that a driver can work under the harvest box B. Provide at intervals. The above-mentioned two side connecting rods 11 and 12 have a height above the ground of 50 cm so that they never touch the height of the strawberries.

[0009]

[Operation and effect of the device]

 Since the present invention has the above-mentioned configuration, it is released from the forward bending posture during the harvesting and harvesting work and the management work, and the unnatural posture of lying on the back with the passenger management work vehicle, and boarded on the traveling vehicle body 1. You can move forward in the ridges in a comfortable position, and at the same time, you can work easily without straining your waist, such as strawberry harvesting and management work. Further, since the harvest box is mounted on the machine body, it is possible to avoid the heavy labor of carrying and carrying the heavy harvest box. Furthermore, if the frame is made of light metal such as aluminum, it can be easily crossed over the ridge and lifted.
