Description

[Detailed Description of the Invention] This invention relates to a jet head angle adjusting device for a house pest control machine that allows the jet head angle to be easily and safely and steplessly adjusted by dial operation.

When spraying chemicals using a greenhouse pest control machine, the setting angle of the spray head must be changed depending on the shape and size of the greenhouse, crop growth conditions, field conditions, etc. As a means, for example, (i) a lever interlocked with the jet head is engaged with one of an appropriate number of recesses arranged in parallel on the scale plate, or (ii) holes arranged in parallel and bored in the angle adjustment plate are used. Measures such as inserting a pin into the jet to adjust the angle of the jet head were used. However, in case (i), since the number of recesses is limited, multi-step angle adjustment, especially fine adjustment, is not possible.
Spraying crops under modern conditions is difficult, and the lever can sometimes disengage from its recess, forcing the lever to be gripped by hand at all times, thus using only a free hand. There is the inconvenience of not being able to perform other operations, and in the case of (ii), the installation operation for fixing the pin in the hole is complicated, and the operator is free from the feeling of complication every time the angle is adjusted. Moreover, as in (i), there are limitations, so multi-step adjustment, especially fine adjustment, is impossible. Therefore, this idea was developed with the intention of correcting the above-mentioned drawbacks, by attaching a plate to the appropriate position of the fan case with a jet head, which is rotatably supported on a support shaft, and attaching a dial to one end of the connecting rod that is linked to this plate. The present invention aims to provide a blower head angle adjusting device for a house pest control machine, in which the blower head can be rotated steplessly to a desired position and held at the desired position by rotating the dial. be.

An example of this invention will be described below with reference to the drawings. A blower B is flange-bonded to the front end of the nozzle N (the left side is the front and the right side is the rear in FIGS. 1 and 2) in which a nozzle (not shown) is installed. is assumed to be in front of the truck F, and the belt 1 is
A compressor K driven by a compressor K is installed below the truck F, and the blower B can be driven by the prime mover M via a belt 2. In the blower B, as shown in FIGS. 2 and 3, both sides of the rotary shaft 4, on which the pulley 3 on which the belt 2 is suspended on the right end are keyed, are housed in bearing casings 5 and 5, respectively. a fan case lid 7, which is rotatably supported on the bearings 6, 6 and slidably contacts the inner surfaces of the bearings 6, 6;
A fan case 8 is fixed to each of the bent portions C, C on the outer peripheral edge of the rotary shaft 4 with fasteners j, j such as bolts, and an impeller 9 fixed approximately at the center of the rotating shaft 4, It is rotatable within the fan case lids 7, 7. In addition, a rectangular connecting plate 10 is fixed to the bolts e and e that are inserted and fixed below the fan case 8, and a support 11 with a stepped portion d screwed perpendicularly to the center of the connecting plate 10 is attached. , a female thread g is carved, and a male thread s is screwed into this female thread g.
The front cover 13 of the truck F is penetrated through the front part of the operation stick 12 which is engraved on the rear side (see Fig. 2).
An operation stick 12 is installed before and after the front cover 13.
Insert pins P and P through to prevent the operation stick 12 from coming off the front cover 13 during internal measurement,
In addition, a dial 14 is fixed to the front end, and the rotation of the dial 14 causes the support body 11 to rotate as the operation stick 12 rotates.
The fan case 8 is connected to the rotating shaft 4 in FIG.
The air supply pipe 15 and the liquid supply pipe 16, which are inserted and fixed above and below the nozzle N, are connected to the compressor K and the chemical tank T, respectively. In the diagram, 17 is a plain washer, 1
Spring washers 19 and 20 are locking hooks for the chemical tank T.

Since this device has the above-mentioned configuration, when the prime mover M is started, the compressor K and the blower B are driven, and the compressed air from the compressor K is used to make the chemical liquid flow into the nozzle from the chemical liquid tank T into fine particles. It is atomized and sprayed from the nozzle N to the objects to be sprayed (not shown) along with pressurized air. However, if necessary, dial 14 now.
When rotating unilaterally, the support body 11, connecting plate 10, and fan case 8 are integrated by the male screw s at the rear of the operation stick 12, and rotate forward (or backward) about the rotation axis 4 in FIG. When the dial 14 is rotated to the desired position, if the rotation of the dial 14 is stopped, the blower B and the jet head N, which are integrated with the connecting plate 10, will also stop rotating at the same time.
The setting angle can be adjusted very easily and stepwise by rotating with one hand, and the lever can be held at the desired position. Or, compared to the conventional means of adjusting the set position of the jet head by inserting and removing a pin into the hole of the angle adjustment plate, the operation is extremely simple and reliable, and during operation, there is no need to slide the hand and remove the finger. There is no risk of it being pinched, and fine angle adjustment is possible, making it easy, safe, and convenient for the user to handle. 11. It is sufficient to assemble the parts such as the connecting plate 10, and it does not become unnecessarily complicated, so it can be manufactured robustly and inexpensively.
This has the practical advantage that by changing the size and length of the male screw s of the operating rod 12, the adjustment range of the jet head N can be arbitrarily selected.
