Abstract

The present invention relates to a traveling device of a traveling pesticide sprayer for spraying pesticides while traveling using a wheelbarrow. In order to avoid pesticides, the sprayer normally sprays pesticides while driving backwards.

However, if the user attaches electric to the wheelbarrow and the user does not match the speed of the cart when driving backward, the handle of the cart is lifted up and the user is in danger of pushing. Due to this problem, the backward driving of the nebulizer requires much effort because it depends on manpower. The present invention relates to a semi-self-driven driving apparatus for a traveling nebulizer equipped with a torque limit on a shaft of a wheel or a reducer so that the driving torque of the motor can be limited to the user's power as a means for solving the difficulty of driving backward.

Description

Apparatus for running of semi-self-propelled type for traveling type-sprayer}

The present invention relates to a semi-self-driven apparatus for driving a portable atomizer for driving a trolley by adding a manpower to the power by constructing a small motor in a driving pesticide sprayer for a unicycle carrying out a pesticide spraying operation (backward walking).

In general, an electric cart means a self-propelled meal that is driven at least on flat land by the power of the cart itself.

In addition, the electric cart is mainly used for forward driving, and it is rare to back up.However, it is very difficult and dangerous to make the trolley walking backward while the user is a servant and the cart is dominant. Configure to Therefore, the driving pesticide sprayer, except for horizontal spraying such as leafy vegetables, performs pesticide spraying while reversing to avoid the sprayed pesticides. As described above, vertical spraying and ceiling spraying depend on manpower due to the problem of backward driving. The burden of effort is inevitable. It is a continuation of the patent application No. 10-2011-0076529 (semi-volume stock driving device) which was filed by the applicant.

Removed the brick phenomenon of the torque limit that is installed for driving backward of the portable atomizer.

In order to prevent the breakdown caused by the overload caused by the brick phenomenon of the torque limit, the body of the trolley is composed of a body to mount the motor combined with the reducer, the torque limit is formed on the shaft of the reducer, and the chain sprocket is connected to the torque limit. Bushing of torque limit is composed of bearing and high reduction gear is used to extend the life of lining of torque limit to increase durability.

The present invention is a soft and smooth to automatically adjust the driving of the pesticide sprayer and the driving of the cart to the user's driving for the reverse pesticide spraying operation relying on the manpower by reversing the power + manpower reaction force for the backward driving of the driving pesticide sprayer It is effective to implement fuzzy function.

The present invention will now be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view of a cordless driving sprayer equipped with the present invention self-actuating driving device, mounted with a pesticide barrel in a unicycle cart and driving without a pesticide string attracted to a rechargeable trolley sprayer for driving the pump using the power of the battery This is a perspective view of a cordless driving sprayer equipped with a diaphragm driving device.

Figure 3 is a perspective view of a streamlined type spraying machine equipped with the present invention self-actuating drive device, equipped with a pesticide cord equipped with a hose automatic winding device on the wheelbarrow and configured to spray the pesticide compressed by the external power to the nozzle This is a perspective view of a streamlined sprayer equipped with a diastolic drive device.

Figure 4 is a block diagram of the present invention self-driving drive device, a frame (1) coupled to the reducer of the motor unit coupled to the driving motor and the reducer is mounted on the frame on which the motor + pump configured at the front of the cart is mounted, the shaft of the reducer A chain sprocket 3 which is configured by attaching a torque limit 2 to the pressure limit 2 and which is pressed by a predetermined pressure (approximately 70 kgf cm) is suitable for not pushing the user in a state where the pesticide container is empty by the torque limit 2. The chain sprocket 3 is configured to drive power to the chain sprocket 5 mounted on the wheel shaft by the chain 4 to drive the wheel.

5 is a configuration diagram of the torque limit of the present invention, the main body 6 is a bolt portion that is coupled to the shaft inlet 7 of the reducer, the inlet body 9 of the bearing 8 and the pressure adjusting tightening nut 10 ( 11). The outside of the bearing 8 introduced into the bearing 8 inlet body 9 is a chain sprocket 3 and two lining 12 is seated, the seated chain sprocket 3 and lining 12 Is pressed by the flange 13, the spring 14, and the fastening nut 10.

The application of the bearing 8 is smoother rotation than the bushing and smooth and easy to perform the purge function of the running speed, there is no breakage caused by overload because the sprocket brick does not occur even for a long time.
