Abstract

PURPOSE:To keep the balance between the front and the rear of a mobile vehicle and to effectively sprinkle agricultural chemicals by providing an agricultural chemicals tank at the rear of the mobile vehicle, disposing a sprinkler pipe in the front and fixing the sprinkler pipe to a front arm. CONSTITUTION:With respect to a mobile agricultural chemicals sprinkler, the agricultural chemicals tank 2 is arranged at the rear of the driver's seat of the mobile vehicle 1 and a sprinkler pipe 3 and a front arm 4 are disposed. The sprinkler pipe 3 capable of being freely exchanged is disposed to the first front arm 401, namely the front half of a front arm 4, and a chemicals feed pipe is provided to the second arm 402, namely the rear half of the front arm 4. Consequently, the balance between the front and the rear of the mobile vehicle is maintained and the operation is stabilized. Since the sprinkler pipe is disposed to the front arm capable of being freely lifted up and down and extended and contracted, the sprinkler pipe can be positioned at any position by operating the front arm.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to improvements in self-propelled pesticide dusters.

<Prior Art and Problems> Conventional pesticide sprayers are equipped with a pesticide tank and a spray pipe on the rear side of a self-propelled vehicle. As a result, it was not possible to work while watching the spraying conditions, and the back of the self-propelled vehicle became heavy, making it difficult to maintain balance.
Occasionally, the product became unstable during spraying operations.

<Means for Solving the Problems> The present invention has been made in view of the above-mentioned prior art, and is based on a method in which a pesticide tank is disposed on the rear side of a self-propelled vehicle, and a spray pipe is disposed on the front side of the self-propelled vehicle. The dispensing pipe was attached to the front arm of the self-propelled vehicle, which can be raised and lowered freely.

Since the present invention is comprised of the above-mentioned means, the front and rear [11+1] balance of the self-propelled vehicle is maintained by the spreading mulberry tank and the fluorocarbon arm, and the spray pipe moves together with the front arm.

<Embodiment> To explain an embodiment of the present invention with reference to the drawings, a self-propelled vehicle 1 is shown as an example running with engine E, and has a pesticide tank 2 behind the driver's seat, and a spray pipe 3 and a front arm in the front. 4 is installed. The dispersion pipe 3 consists of a pair of left and right parts, both of which are bendable drug delivery pipes (not shown). It is connected to the chemical tank 2 and configured so that the agricultural chemical tank 2 can be operated from the driver's seat to spray e-drops from the spray pipe 3 and to stop the spraying.

Each of the pair of dispersion pipes 3 is attached to a first arm 401 constituting the front half of the front arm 4 in a freely replaceable manner,
Second arm 402 forming the rear half of front arm 4
A medicine whistle (not shown) is disposed at the front arm 4, and the dispensing pipe 3 and the 17th arm 401 of the front arm 4 are configured in a V-shaped configuration. Therefore, the spraying pipe 3 is arranged in the 17th-mute 40 such that a large number of nozzles 301 face downward at the pesticide spraying 1-1;'J.
I will attach it to 1. The front arms 4 consist of a pair of left and right, in which the base end of a first arm 401 constituting the front half and the distal end of a second arm 402 constituting the first half are pivoted to each other, and The shaft 4 is equipped with a hydraulic mechanism 5 consisting of a hydraulic cylinder and a hydraulic piston rod, and the first arm 401 is moved to the second arm 4 by the expansion and contraction operation of the hydraulic mechanism.
It rotates around the 4th part between the fin and the fin (see Figures 3 and 4). A pair of Freon [
- The arm 4 attaches the λ奄9i: part of the second arm 402 to a pair of left and right turns'vJi403, and each of these rotating plates can be freely rotated in the front and rear directions on both the left and right sides of the self-propelled vehicle 1 in front of the driver's seat. By attaching it to the front side of the self-propelled vehicle 1, it is arranged so as to be rotatable in the front and rear directions with respect to the self-propelled vehicle 1 (see FIGS. 1 and 2). The pair of Freon 1-arms 4 are equipped with a hydraulic mechanism 6 consisting of a hydraulic cylinder and a hydraulic piston rod between the 1J end of the second arm 402 and the pair of co-moving plates 403, and the hydraulic mechanism is extended and contracted. As a result, it is configured to undulate in the front-rear direction and laterally around the pivoted portion with the rotating plate 4 ( ) 3 . (See Figure 1 for the up-and-down motion in the front-back direction, and Figures 3 and 4 for the up-and-down motion in the lateral direction). A pair of rotating plates 403 on which a pair of front arms 4 are pivoted are attached to both left and right ends of a movable frame 7, which is arranged on the front side of the self-propelled vehicle m1 and can freely move up and down and tilt forward. [By doing so, the front arms 4 are placed on both right sides of the front side of the self-propelled vehicle 1, and thus the pair of front arms 4 are disposed on both the left and right sides of the front side of the self-propelled vehicle 1. Cover composition. In addition, when the movable frame 7 is moved up and down, the hydraulic mechanism 8 consisting of a hydraulic cylinder and a hydraulic piston +1 is operated to extend and retract, and when the movable frame 7 is moved up and down, the hydraulic mechanism 8 is configured as follows: The hydraulic mechanism 9 is operated to expand and contract.

Next, to explain the first usage, the dispersion pipe 3 and the front arm 4 are raised from the storage position shown by the solid line in the first figure to the upright position shown by the imaginary line. The erected position of this imaginary line is the solid line position shown in the second diagram.

From the standing position shown by the solid line in Figure 2, through the forward rotation process shown by the imaginary line, the forward rotation end position j is shown by the solid line in Figure 3.
1 FIIt up to α! Shrink. The solid line position shown in the third figure is a position where the straight line connecting the pair of front wheels 1-7-4 intersects perpendicularly with the axis of the self-propelled vehicle. It is tilted sideways from the solid line position shown in the third figure to the laid-down position (not shown by the imaginary line) to reach the solid line position shown in the fourth figure. , move to the solid line position in Figure 4, extend the bent first arm 401 as shown in the imaginary line, and at the same time open the spray pipe 3 to direct the many nozzles 301 downward, thereby eliminating the pesticide. 15 Start work.

If you follow the procedure in reverse to the usage method described above, a pair of spray pipes 3
And a pair of Freon 1 to arm 4 can be stored.

All the above-mentioned arm operations, pesticide spraying work, etc. are performed from the driver's seat.

<Effects of the Invention> The present invention has a pesticide tank on the rear side of the self-propelled vehicle and a spray pipe on the front arm of the self-propelled vehicle, so that the front and rear balance of the self-propelled Qi is maintained, and it can be The risk of losing balance is eliminated, the work can be carried out with good stability, and the spraying status of pesticides can be checked. Spraying work can be carried out with JA approval, and it is possible to quickly create the necessary arrangements for effective spraying, such as adjusting the amount of spraying and determining the spraying position of the spray tube. Since the spray pipe is attached to the front arm of the self-propelled vehicle, which can be raised and lowered freely, it is possible to position the spray pipe in various positions, store it, and cover it by moving the front arm. Become,
Not only is it convenient to use and store, but it also reduces the risk of damage to the spray pipe due to wind power, obstacles, etc., protects the spray pipe from such damage, and allows safe use over a long period of time.

Therefore, the well-known self-propelled pesticide duster can be significantly improved.
You can achieve your intended purpose.
