DESCRIPTION

The background of the invention field

To do farming work in the field especial in the wet rice paddy is an extremely hard labor work. The farmer's feet need to step into the muddy rice paddy, the body needs to have a bow position frequently, as well as exist for a long time. This invention is trying to provide a better solution for the farming and garden work such as by having a good and comfortable position design, skilled force using and mechanical principles etc. Nowadays, there are some agriculture engine drive machines to do such job in the current market. However, considering the cost and size, this device has its advantages of simple, lower cost and suitable for family using, as well as convenient product because it can ride on either field (dry/wet) or very small banks in the farmland. Especially suitable for those remote, mountain area or natural reserved area where is not suitable for large engine oil/gasoline drive tractor.

The function of the multi-function bike accessory parts

Considering the cost, the said multi-function bike machine can be an ordinary bike combine with some different designed accessory parts become a multi-function bike to carry out "throw seedling rice plant", useless grass removal, normal checking work in the water rice paddy etc. Most of the parts are plug-and-use, it means easily install and removal parts. A specific design multi-function bike is recommend for getting better effective, but the removable accessory parts are same. In order to make the bike ride on the wet or water rice paddy and further to do the farming operation, two set of floating slide boards are prepared accessories. When the spring season comes, the farmers need separate and plant small rice seedling in the mud rice paddy. The two set of "plug-and- ride" floating slide board can manual install on the bike (figure 1, 8) to do such plant work. Usually, a bike's weight is 10- 15kg, a person weight about 60kg, when a person ride ordinary bike in the rice paddy that fill with water and mud, the wheels will go downwards about 120mm- 150mm height, and could not make balance due to the stick mud in water rice paddy; It will go downwards about 20 mm height in relative dry grown rice field. In order to ride on the surface field, there are a set of floating slide board and supporting slide board that will be installed, and length of rolling arm plate is designed to at least 65mm for the rear wheel floating board based on above measurement data (Figure 7). Since the distance of two groups of rice plant is average 350mm (a group of rice plant usually have 10-15 rice plants, the group's distance is around 260mm - 400mm). To avoid overwhelming the planted rice seeding or grown rice plants, the distance of the floating board to the rear wheel are: left 290mm, right 230mm and the distance of centre gear of the convey system to the rolling arm plate are: left 210mm, right 180mm. The distance of bolt stanchion to the rolling arm is 100 mm long (Figure 6. & 7). The path (small country road between the rice paddy field) usually around 400 - 550 mm width. Since the whole width of multi-function bike will around 460 mm. It can ride on the small country road, and the rolling arm plates are only loading self floating board weight, hence it is empty rolling. Once the multi-function bike step into wet rice field, the floating board touch water and mud, the bike can "walk" or "jump" in the mud field powered by man force or by manually operate a small motor. Combine the carrying basket in front of the handlebar which fills with rice seedling, the farmer can carry out the "throw rice seedling" work in the empty paddy field. And when the summer, autumn come, the other accessories such as a "harrow- like" floating board (figure 11) and other possible accessories can fixed into bike to do remove useless grass, normal check, etc without step farmer's feet into the mud field.

Additional accessory part is a pair of specific application shoes, it has a height adjustable heel in order to fit the using situation such as in case farmer need step into the mud field by feet, then adjust heel length to longer, otherwise, keep the heel in normal height or temporarily remove it from the shoes in order to step on the bike.

The description of the structure of the invention

The invention is a kind of bike machine with a set of the "plug-and-ride" floating slide board and a supporting slide board based on the using situation. It is designed to fit ordinary bike because of cost. However, it is recommended use a specific multi-function bike in order to improve the effective. For example the two main wheels has a special design in order to ride on the both dry field and wet rice plant paddy, the wheel tire is more thick with the deep rim than normal bike wheel; the spoke of two wheel are made of rust resistant material, the axle for the two main tires are much longer than the ordinary bike in order to fix with the different farming tools to carry out the farming or garden mission. Usually combined a specific handle bar blanket is necessary and ordinary. In order to carry and satisfy the farming or gardening operation. Here, it does not display it.

The two set of "plug-and-ride" accessories are slide board that have different design and function (figure 1 and figure 8). The small set of accessory can install at the down tube which located behind the fore-wheel (figure 9), a pedal clamping apparatus (figure 10) will regularly push it when bike move forward. When multi-function bike stop, the small slide boards has supporting function to avoid the fore wheel turn over. So it has supporting and balance function when the bike is ride on the wet mud field. Another big set floating slide board has its own mechanical convey system which concludes a gear with axle (transmitting shaft) and a chain-set connect with bike main chain-set it is installed on the rear wheel and support by a pair of fixed stainless steel tube and a pair of additional removable steel tube (figure 1),. When bike move forward, it also supported by the "leg-like" bolt stanchion (Figure 12). A part of man power force on the pedals through the main gear will be transmitted to the said accessory floating board by the convey system and rolling arm plate, (figurel, 2, 3, 4, 5). The said big longer floating slide board has another import function except the floating function. Under the floating board, there are two thin, curves, rectangle structures (Figure 2), it can be dig into the mud soil and propel the bike "walk" and "jump" on the mud field by man power or plant oil driven small motor (further study) through the bike pedals.

Alternative floating board can be apply that have more rectangle curve structures, like harrow, can dig and removal useless grass in the rice filed (figurel l).The other accessory utensils also can be designed. Its can be installed in the both side of the wheel axle based on seasoning farm work.

The extension of possible further development

A small floating slide board also can be installed with air/oil suspension fork [2]. Extend the fork-tube combine to a small slide board by oil/air pneumatic principle to improve the convenient of the current small slide board.

Since manpower force is limited for the loading weight and speed combined a small motor, electronic generator and a small rechargeable battery can reduce consuming the force of rider that is required in the short time. When farmers at home, he/she or his/her family member can do some exercise work to recharge battery. However, it may rise up the cost of the machine when it is produced in factory. And once use oil motor it will cost and consider environmental pollution problem. The plant oil is recommended to drive the small motor because it is more convenient natural resource in farm area.

MISCELLANEOUS DOCUMENT

Two experiments were set up.

An agriculture field data measurement

A measurement experiment is set up. The location was chosen in the agriculture rice paddy field nearby a small city. The data are collected and used in the description.

Mechanical experiment:

These are some of mechanical experiment photos. It includes the rear wheel's "plug- and-ride" accessory mechanical parts, its "leg-like" support bolt stanchion made of steel. The floating slide board initial made of iron alloy, shape is correct, but it is two heavy for the rolling arm plates, after re-strong the rolling arm plates, add one more plate, the connect part, and re-made a lighter aluminum alloy floating slide board, it can work on the unload situation, but the material still need be considered. It is recommended that the material use similar lighter, but stronger compound metal.
