Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a speed sprayer, and more specifically to a speed sprayer that prevents overturning by moving the center of gravity of a loaded chemical tank to the mountain side. .

(Prior art) Conventional speed sprayers are prone to overturning on slopes because the main part of the load is applied to the valley side, and the added load causes the suspension, tires, etc. to sink, making this tendency even more likely. In addition, the recoil from the steep slope, the chemical liquid in the chemical liquid tank moving toward the valley side, and the center of gravity shifting extremely, and the kinetic energy of these movements are added, and the running performance on slopes becomes significantly worse. It is easy to cause defects such as deterioration.

(Purpose of the invention) This invention was made in view of the above points, and its purpose is to provide a speed sprayer that does not overturn even on slopes. A detection sensor for detection, a center of gravity moving device for returning the chemical tank on the chassis to the mountain side based on the signal from the detection sensor, and a center of gravity moving device that can swing around the bottom on the chassis, linked to the center of gravity moving device. It has a chemical solution tank supported by.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1, a center pin 14 is provided on the differential gear 12 at the rear of the speed sprayer 10.
The lower part of the chemical liquid tank 16 having an expanded head shape is placed on the center pin 14 in the vehicle axis direction of 0.
It is fixed so that it can swing left and right around the center. Electrically motor-driven variable length absorbers 20a and 20b are provided on the support cylinder 18 that protects the drive shaft extending left and right of the differential gear 12 or on the frame of the speed sprayer 10, and the absorbers 20a and 20b are electrically driven by a motor, and are installed on the left and right side of the chemical tank 16. It is pin-coupled to the bottom 22 of the. A variable length absorber 20 and an inclination detection sensor 24 are used to move the center of gravity of the chemical tank 16 and the chemical solution therein further toward the mountain side by always moving the chemical tank 16 horizontally or more toward the mountain side. FIG. 2 shows a means for moving the center of gravity position consisting of a battery 26 and a battery 26. This means consists of a variable length absorber 20 and a liquid mercury switch connected in series to the battery 26, and the liquid mercury switch functions as an inclination detection sensor and an energization switch.

In other embodiments, a hydraulic cylinder, rack and pinion, jack, etc. may be used in place of the variable length absorber. Furthermore, in consideration of the fact that not only the chemical tank 16 but also the front axle is susceptible to overturning if the front axle's load is on the valley side and the sheath spring sinks, a center of gravity moving means is provided on the frame etc. in this case as well. Therefore, driving safety when driving on rough roads can be further improved.

(Effect of the invention) When the chemical liquid tank is moved to the mountain side by the device for moving the center of gravity of the chemical liquid tank on a slope of the speed sprayer, the chemical liquid weighing more than the chemical liquid tank also moves to the mountain side. It is possible to reduce the adverse effects of chemical solutions that tend to move toward the valley side, and it is possible to improve the stable running performance of the speed sprayer on slopes.

Although the present invention has been variously explained above with reference to preferred embodiments, the invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
