Description

[Detailed explanation of the invention] [Industrial application field] A series of equipment including a receiver tank, compressor, and battery is built into the space between the frame supporting the bucket and the bucket, and the compressor automatically supplies the receiver tank with a constant pressure. This device operates an air cylinder via a valve to open and close a discharge gate.

[Conventional technology]

Up until now, the air cylinder and receiver tank have been installed in a bucket, but there are two methods of supplying air to the receiver tank from a separately installed compressor via a hose, either by hand or by using a special device. The compressor was built into the bucket, but the power source used to run an electric wire from outside the bucket to drive the compressor.

[Problem that the invention attempts to solve]

This is an idea that attempts to solve the problems that conventional devices require manpower, lack reliability even as special devices, and even if the compressor is built into the bucket, it is troublesome to draw electric wires from outside.

[Means for solving problems]

A receiver tank is provided on one side of the lower part of the frame surrounding the bucket, a compressor and a battery are attached to the frame in the space formed by the frame and the bucket, and metal fittings are installed between one side of the frame and the bucket. , An air cylinder is pivoted to the metal fitting with the rod facing downward, and a gate opening/closing lever attached to the lower end of the bucket so as to be openable and closable is pivoted to the tip of the air cylinder rod, and the drive part of the compressor and battery are connected. Connect the
In addition to connecting the compressor and receiver tank with a hose, the receiver tank and air cylinder are connected with a hose through a valve, and a series of devices consisting of an air cylinder, receiver tank, compressor, and battery are built into the bucket to open and close the gate. By doing so, we have solved the troubles we have had so far.

[Effect]

By closing the switch installed in the circuit connecting the battery and compressor, the compressor is activated and air is automatically supplied to the receiver tank until a constant pressure is reached, and the air cylinder and receiver tank are connected as necessary. The gate of the bucket is opened and closed by opening and closing the on-off valve provided on the hose and operating the air cylinder.

〔Example〕

A receiver tank 3 is installed horizontally on one side of the lower part of a frame 2 surrounding the bucket 1, and a compressor 5 and a battery 6 are appropriately attached to the frame 2 in a space 4 formed by the frame 2 and the bucket 1. A metal fitting 7 is provided between one side of the frame 2 and the bucket, an air cylinder 8 is pivoted to the metal fitting 7 with the rod 9 facing downward, and a gate 10 is attached to the lower end of the bucket 1 so as to be openable and closable. The open/close lever 11 of the air cylinder 8 is pivotally connected to the tip of the rod 9 of the air cylinder 8, and the drive section of the compressor 5 and the battery 6 are connected via the open/close switch 12 to
The compressor 5 and the receiver tank 3 are connected by a hose 14, and the receiver tank 3 and the air cylinder 8 are connected by a switching valve 15.
They are connected by a hose 16 through the.

To explain the structure of the opening/closing lever 11, the horizontal part 1
T-shaped lever 24 with a vertical portion 18 in the center of 7
The crossing portion 19 of the rod 9 is pivotally connected to a plate 25 provided on the frame 2, and the tip of the rod 9 is pivotally connected to the tip of the vertical portion 18, and one end of the horizontal portion 19 (the lower end in the figure) and one side gate 10 (the lower end in the figure) are connected. In this case, the outer end of the left side gate) is connected with the lever 20.

The other end of the horizontal part 17 (the upper end in the figure) and the inner end of the gate 10 (the right side gate in the figure) are connected by a lever 21, and as the rod 9 descends, the T-shaped lever 11 rotates clockwise. By rotating the gate 10, the left gate 10 is pulled up to the left using the pivot portion 22 as a fulcrum, and the right gate 10 is pivoted to the right using the pivot portion 22 as a fulcrum to open the gates 10, 10. . Note that 23 indicates a safety valve.

〔effect〕

It has a simple configuration, can be omitted, is easy to work with, is safe and reliable, and has an overall low cost, which is advantageous compared to conventional equipment.
