For details, improve the attitude of harvesting strawberries in farming,
The present invention relates to a material suitable for improving efficiency due to reduction of fatigue and work comfort.

340 hours of work labor during the strawberry harvest period (April to October)
80% of 10a is work in a forward bending posture, which is effective in improving labor for strawberry growers.

[Prior Art] Conventionally, this kind of thing is as follows. Carefully picking mature strawberries in a forward bending, crouching or knee-standing condition.

At the peak of work, about 15 hours of work a day continue.

[Problems to be Solved by the Invention] The conventional techniques described above have the following problems.

As a result, symptoms such as stiff shoulders, low back pain, heavy head, and tired eyes occur.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide the following.

By sitting on an automatically traveling trolley and working, work efficiency, labor saving, and work posture can be improved.

As a result, weight reduction, self-propelled (two-seater) battery drive, simplification of mechanism, ultra-low speed, stepless selection of speed, low cost, durability, etc. are achieved.

[Means for Solving the Problem] In order to achieve the above object, the present invention is as follows.

That is, the thing of the present application is a flat square top plate 2A, front left and right legs 2B hung at the front corners of the top plate, rear left and right legs 2C hung at the rear corners, and front left. leg
2B and the left lower frame 2D hung between the rear left leg 2C and the right lower frame hung between the front right leg 2B and the rear right leg 2C
The front wheel 3 which is a free wheel is attached to the lower ends of the front left and right legs 2B of the frame 2 which is configured to straddle the ridge from 2E, and the traveling power battery is used as the power source at the lower ends of the rear left and right legs 2C. A driving wheel rubber tire 4 is attached, a left seat 5 is provided substantially rearward of the left lower frame 2D, and a right seat 6 is provided substantially rearwardly of the right lower frame 2E. Near the front of the frame 2D and the lower right frame 2E
Steps to correspond to the left and right seats in the front position of
5A and 6A are provided, and the left and right pedestals 7 are disposed in front of the left and right side surfaces of the top plate 2A in the frame 2 at a position slightly lower than the level of the top plate, and on the upper surface of the top plate 2A in the frame 2. The provided temporary storage shelves 8 are self-propelled riding-type harvesting work carts in which an appropriate number of shelves are supported by supporting legs.

In this case, the following can be done.

A. The seat can be installed at a position about 27 cm above the ground.

B. The seat can be configured to rotate 30 ° left and right.

[Operation] The device of the present invention operates as follows.

When moving forward during the harvesting work, the wheel shafts are directly connected and go straight.

When moving before and after harvesting work, the front wheels are set freely, the drive shaft clutch is disengaged and pushed manually.

Embodiments of the Invention Embodiments will be described with reference to the drawings.

1 is the self-propelled riding-type harvesting work cart of the present invention.

Reference numeral 2 denotes a frame, which is a flat rectangular top plate 2A, front left and right legs 2B hung at the front corners of the top plate, rear left and right legs 2C hung at the rear corners, and front left legs. 2B and a left lower frame 2D hung between the rear left leg 2C and a right lower frame 2E hung between the front right leg 2B and the rear right leg 2C. .

Therefore, the frame 2 is configured to straddle the ridge.

A front wheel 3 which is a free wheel is attached to the lower ends of the front left and right legs 2B.

Numeral 4 is a drive rubber wheel tire attached to the lower ends of the rear left and right legs 2C and is 8.00-4. 4A is a running power battery (12V) that serves as a power source.

4B is a speed reducer for traveling at a low speed with a DC motor, which is 1/40.

4C is a low speed, high speed transmission gear, low speed range is 1.2-2.22c
The range of m / sec and high speed is 5.14-9.15 cm / sec.

4D is a speed change knob, which is a volume that can freely change the speed range of low speed or high speed position.

4E is a drive shaft, which is directly connected during work and rotates simultaneously.

4F is a chain case that transmits the drive wheel shaft sprockets from the drive shaft sprockets.

5 is the left and right seats provided substantially rearward of the left lower frame 2D and 6 is substantially rearward of the right lower frame 2E, but both hands are close to the strawberry bed at a low riding position,
It is configured to rotate 30 ° left and right.

In this case, the optimum occupant position is about 27 cm above the ground.

5A is a step substantially in front of the left lower frame 2D, and 6A is a step in front of the right lower frame 2E corresponding to the left and right seats, respectively, and can be positioned depending on the length and posture of the foot.

Reference numeral 7 denotes left and right pedestals arranged in front of the left and right side surfaces of the top plate 2A of the frame 2 at a position slightly lower than the level of the top plate, and is a place for temporarily placing a strawberry folding box.

Reference numeral 8 denotes a temporary storage shelf arranged on the top surface of the top plate 2A of the frame 2, and is constituted by supporting a proper number (three steps in the figure) of shelf plates by supporting legs.

When the folding box is full, put it in the shelf.

About 20 kg of strawberries can be stored.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

1. Compared with the conventional strawberry harvesting method, you can work in a comfortable posture.

2. Efficiency can be improved because you can select a constant speed or a speed that matches the yield.

3. Reasonable work can be done because necessary materials (carrying boxes, containers) and harvested items can be loaded.

4.Since you are sitting, you can concentrate on the harvest and improve your comfort.

5. The stand and the temporary storage shelf are placed on the frame that connects the left and right traveling devices, ensuring visibility in front of the vehicle while traveling, and avoiding damage to the crop body. ) On top of which you can place crops.

6. The present invention was devised for the purpose of lightening agricultural work not only in outdoor cultivation but also in closed working environments such as greenhouses and greenhouses.

In this regard, the harvesting work cart quoted above has an internal combustion engine (engine) as a power source for the traveling part, so exhaust gas and noise are generated, so use in the closed work environment as described above. It is considered not suitable for.

Further, it is clear that it is difficult to make the work of a work dolly without a power source light work because the work of the work dolly uses the feet of the worker.

In view of such an actual situation, the present invention uses a battery and an electric motor mounted on a work trolley as a power source, does not generate exhaust gas and noise, and can maintain a good working environment. Therefore, the light labor of agricultural work is realized.
