Description

Wireless remote slave initial {Remote control Weeder}

Agriculture can be said to be a war with weeds, and how to manage weeds can determine the success or failure of agriculture, and consequently it affects the productivity of agriculture according to the somewhat of herb management cost. In modern agriculture aiming at mass production, chemical fertilizers and pesticides have been used to solve the food shortage problem of the earth, but the environmental destruction caused by the impact has reached serious level. In order to preserve the sustainable food and environment, Environment-friendly agriculture that does not use, in particular, does not use herbicides is spreading. Herbicides are the most effective agricultural chemicals, and they enable the production of large amounts of plants at a time by isolating them from weeds. The herbicide, which can be applied as a whole or selective herbicide, has a direct influence on the destruction of the soil as well as the change of vegetation, and it is recognized as a main cause of destruction of the sustainable production environment due to a large amount of residuals. In addition, as a cause of adult diseases such as atopy and carcinogenesis of juveniles, farming methods that do not use herbicides are developed and recognized by consumers.

As a non-herbicide-free farming method, mulching vine is used to inhibit the germination of weeds, which is mainly used in fruits and vegetables. Prior to sowing or planting the crops, mulching vinyl is coated to inhibit the germination of the weeds and allow the crops to grow unimpeded from the weeds. The use of mulching vinyl can be liberated from weeds, but it takes labor to collect and dispose of mulching vinyl, collect and dispose of mulching vinyl, and put a lot of cost into the country.

Mulching Vinyl non-herbicide methods include mechanical weed cutting machines. As shown in the figure, a lawn mower that removes a large area of weeds by grafting on various farm machinery, and a portable machine used in small areas (mausoleums) are used. A variety of products are used for mechanically weeding by using power and various products are used. However, products for the remote weeding apparatus implemented in the present invention are not disclosed.

As shown in the figure, the main types of weeding of large-scale area are working machines which are attached to agricultural machines such as agricultural management machines, tillage machines, SS machines, tractors and the like. However, as shown in the figure, these agricultural machines are restricted by obstacles such as stools or branches due to engine or basic machine configuration (height, width), so there are many untreated areas, Safety, and fatigue. In addition, for the weeding in the orchard, it is necessary to have skill of manipulating the machine,

In order to overcome these disadvantages, we have constructed a small, low-height weeding device and remotely operate it to overcome facilities and obstacles such as hanging branches, branches, irrigation hoses, We have developed a remote controlled self-propelled lawn mower that can be weeded so that it hardly occurs.

In the early days of wireless teleportation, the following effects are expected. ① Since it does not cause the occurrence of micro-organisms, it is expected to improve efficiency of plant and pest control by improving the efficiency of control of weeds by more than 98% and control efficiency by 20%.

② Most riding or walking type farming machines are extremely fatigued because they are required to be careful to prepare for the safety from the branches in the orchard, and the cause of musculoskeletal diseases is caused by mechanical vibration or noise. This is expected to contribute greatly to the health and safety of farm workers, especially fruit and vegetable managers.

③ Wireless remote control device has automatic function such as self-obstacle avoidance function, so it is not difficult for woman or older worker to drive, and it is expected to help a lot of relieving burden of weeding work.

The inventor of the present invention is as follows. The body 1 is a basic frame of a mower, which is welded with a steel material. The vehicle body 1 is provided with a front guard 2, auxiliary wheels 35 and 36, weed blades 13 and 14, an engine 11, a generator 22, drive wheels 33 and 34, a rechargeable battery 37 And the rear guard 3 are assembled in this order.

The front guard (2) is a device that protects the machine from faeces, crops, or obstacles during the work in progress, and round pipe is made round in shape and attached with proximity sensor and contact sensor if necessary, Stop, and so on.

The auxiliary wheels (35, 36) are provided on the front left and right sides to adjust the supporting and weaving height of the vehicle body, and a castor wheel with smooth rotation is mounted to facilitate steering. The auxiliary wheels (35, 36) can be provided with two left and right wheels, or one at the center, so that the weed height can be freely and automatically maintained on the uneven terrain.

As another embodiment of adjusting the weeding height, slider type supports 40 and 42 can be constructed as shown in Figs. 3 and 4. The slider support pedestal 40 can be formed as a front U-shaped structure or a hinge type 42 and can be held at a constant height from the ground using a spring 41 having elasticity So that the slider support can be freely rotated with respect to the vehicle body.

Auxiliary wheels or slider supports are not important in a flat orchard or on the ground, but they have the ability to automatically adjust the minimum height of the weed control on uneven land, ridges and valleys.

The basic power of the lawn mower of the present invention is a gasoline engine 11 of about 7 horsepower. The engine mounted on the car body is divided into two rotating outputs, one is used for driving the grass blade, and the other pulley is used for driving the generator.

The herbicide blades (13, 14) constitute one herbaceous blade with two knife-type flattened razor blades, and the first and second herbicidal blades are rotatively driven by being installed side by side on the central part of the mower each. The driving of the lawn mower uses the "V" belt 12 to drive the primary herbicide blade 13 and the secondary herbicide blade 14 to be accelerated by about 20%. The driving of the weed blade by the engine is directly driven by interlocking.

The engine rotational force is generated by driving the generator 22 through another pulley 21. [ The developed electricity drives the direct DC motors 31, 32 during engine operation to operate the forward and reverse drive wheels, and the electricity of the spare is charged into the battery 37. [ The electricity charged in the battery 37 is used for the engine starting electric engine and the engine engine for simultaneous running.

Wheel drive wheels (33, 34) are installed on the left and right sides when the lawn mower moves, advances, reverses, and steers left and right. The DC motors 31 and 32 are directly connected to the left and right drive wheels 33 and 34, respectively. The left and right DC motors 31 and 32 are operated simultaneously when advancing at the time of traveling, and the left and right DC motors are operated and steered at the time of left and right rotations.

The rechargeable battery 37 charges the electricity generated from the generator 22 through the regulator and charges and installs the battery for the vehicle in parallel. The battery charging electricity is used for engine starting or engine running simultaneously.

The remote control is a joystick type (Figure 5) that is commercialized as a remote control of general remote control product. It can start and stop the engine, adjust the rotational speed of the weed blades, move forward and backward of the mower, It is set to the control level. The remote control is transmitted to a separate remote controller (FIG. 5) and communicates with the receiver 50 attached to the vehicle body to perform remote control.
