Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is applicable to mobile layer I! Regarding the towed soil disinfection machine, in detail, it is a soil disinfection machine that runs while intermittently injecting disinfectant in proportion to the distance traveled by the mobile agricultural machine.

Conventional technology and problems Conventional soil disinfection machines of this type include a ground wheel drive type in which the disinfectant injection pump is operated in conjunction with a ground wheel installed on the body of the disinfection machine, and a ground wheel drive type in which the disinfectant injection pump is operated in conjunction with a ground wheel installed in the body of the disinfection machine, and a ground wheel drive type in which the disinfectant injection pump is operated in conjunction with a ground wheel installed in the body of the disinfection machine, and a type in which the disinfectant injection pump is operated in conjunction with a ground wheel installed in the body of the disinfection machine. There is also a motor-driven type.

However, the ground wheel drive type requires a large amount of torque to drive the pump, which causes the ground wheel to slip and cause unstable rotation, and the disadvantage is that the amount of disinfectant dispensed is not proportional to the distance traveled by the mobile agricultural machine. . However, in the conventional machine, Fig. 6, Fig. 7
As shown in the diagram, 91 ground wheels must be installed for each injection pump (7), which not only increases the weight but also moves the center of gravity to the rear, causing the sterilizer to bounce upward when changing direction while driving. To lift a large mobile agricultural machine that can withstand it (
There was the inconvenience of having to use 1).

In addition, with motor-driven models, the injection pump operates regardless of whether the aircraft is moving, so even if the aircraft stops moving, for example,
There were some problems, such as only the injection pump was working and disinfectant was being poured out.

Means for Solving the Problems The present invention aims to eliminate the drawbacks of the above-mentioned prior art, and provides a soil disinfection machine in which a disinfectant solution is intermittently poured out in proportion to the travel distance of a mobile agricultural machine. It is something.

Further, the present invention provides a soil disinfection machine that is small and lightweight and can be towed by a mobile agricultural machine.

That is, this invention provides a grounding wheel provided on a moving layer II traction type machine frame with a control device that issues an electrical command as the grounding wheel rotates, and a disinfectant injection system mounted on the machine frame. The gist of the present invention is a structure of a soil disinfection machine characterized in that a drive motor for a pump is made to be able to rotate intermittently in response to electrical commands from the above-mentioned device.

Operation This invention is constructed so that the control device operates in conjunction with the grounding wheel, but since its load is small, the grounding wheel rotates in proportion to the travel of the mobile agricultural machine without slipping or the like.

Accordingly, the electric command issued from the control device causes the disinfectant injection pump to operate correctly via the drive motor, and disinfectant is intermittently spouted in proportion to the travel distance.

This invention also provides a drive motor for a disinfectant injection pump.
Since it can now be electrically controlled by a control device installed on the grounding wheel, the disinfection device can be made smaller and lighter than conventional machines.

Embodiment To explain this invention with reference to the illustrated embodiment, (1) is the body of a mobile agricultural machine, and the machine frame (3) of the soil disinfection machine according to the present invention can be freely towed at the rear via a connecting shaft ('2). At the bottom of the machine frame (3), a pressure roller (4) and a grounding wheel (9) are installed so that they can move freely, and at the top, there is a disinfectant storage tank (6) and a container inside the tank (6). It is equipped with a pump (7) that pumps out and dispenses disinfectant and a motor that drives it. (9) is a control device that can rotate freely in conjunction with the grounding wheel (5). A starting switch (+2) is formed by elastically supporting a sensing roll 01) that can be fitted into a recess provided on the periphery of the starting cam, and a sensing roll θ1) that can be inserted into the recess provided on the periphery of the starting cam.
When the starting switch 0 is inserted into the recess, the starting switch 0 is turned on, and when it is removed from the recessed part, it is turned off. However, since the load on the grounding wheel (C) of the control device (9) is extremely small, the grounding wheel (5) rotates smoothly as the machine frame (3) moves, and the control device (9) is operated accurately. become.

On the other hand, a stop cam 03) is provided on the output shaft of the drive motor, and an appropriate number of recesses are carved in the periphery of the stop cam 03). When the sensing roll of the stop switch 010 is inserted into this recess, the stop switch 04 is turned off, and when it is removed from the recess, it is turned on. Therefore, the drive motor (to) rotates according to the electrical command from the control device (9),
The sensing roll of the stop switch 04) is the stop cam (2)
When pushed out from the next recess, the motor 6 continues to rotate, and the sensing roll Q51 fits into the next recess and stops. However, the control device (9) is rotating together with the grounding wheel (5) as the machine frame (3) runs, regardless of whether the motor (2) has stopped, so the sensing roll (Qt) of the starting switch (02) is located in the recess of the starting cam. ) is inserted, the motor ■ will rotate again. Then, the sensing roll 0!11 of the stop switch θ4) is pushed out of one recess of the stop cam a, and the output shaft rotates until it fits into the next recess. In this way, the injection pump (2) operates in conjunction with the drive motor 18, and intermittently spouts out the disinfectant solution in the tank (16).

Effects of the Invention The present invention is configured as described above, and since the grounding wheel rotates smoothly as the mobile agricultural machine travels, the disinfectant sprayed from the pump is proportional to the travel distance of the mobile agricultural machine. It has the effect of being ejected accurately.

Further, according to the present invention, since a large number of pumps can be controlled by a single control device, the machine frame can be made lighter and smaller, and can be towed by a small mobile agricultural implement.
