Safety amusement excavator

Abstract

The invention discloses a safety amusement excavator and relates to an amusement device. The safety amusement excavator comprises a base and a control box arranged at the front end of the base. A housing covering the base is arranged on the rear side of the control box of the base, a seat is arranged on the housing, a motor, a hydraulic pump, a coin inserting device and a hydraulic oil tank are arranged in the housing, a rotary oil cylinder pushing the base to rotate with respect to a base supporting seat is arranged on the lower side of the base, the hydraulic pump controls works of a large arm oil cylinder, a small arm oil cylinder, an excavator bucket oil cylinder and the rotary oil cylinder respectively through a manually-operated hydraulic quadruple valve, and a control handle for manually controlling the work of the manually-operated hydraulic quadruple valve is arranged on the control box. The seat comprises a small seat formed by the downwards-sunken front end of the housing and a large seat installed on the upper surface of the housing. Safety sensors are arranged on two sides of the front end of the control box respectively and are connected with a controller through circuits, and the controller is connected with the motor through a circuit and can control startup or stop of the motor through a control signal. It can be ensured that the safety amusement excavator is safe and reliable in the amusement process, and accidents are avoided.

Description

technical field [0001] The invention relates to an amusement device, in particular to an amusement excavator. Background technique [0002] Excavators are widely used in various engineering fields, but due to their high price and difficult operation, they are not well known to the general public. In order for the general public to understand excavators, some amusement excavators have appeared on the market, such as patent application number 201210301047.2 The amusement excavator described in the Chinese Invention Patent Application No. includes a casing, a bracket, a power unit, a control unit, a hydraulic system, a seat, a rotary shaft, and a bucket, and it also includes a timing device for timing, for controlling The manual hydraulic three-way valve for operation, the coin acceptor for coin insertion, etc., and the power device is driven by a motor. This amusement excavator can be used for children and adults to play, and has a simple structure and low production cost. Ho...

AI Technical Summary

Problems solved by technology

However, this kind of amusement excavator uses a manual hydraulic three-way valve, which can only make the actuator push the slewing arm and the bucket to move, and the pedal cannot rotate relative to the bracket at the bottom. The effect is the same as that of a real excavator. When this kind of amusement excavator is working, if there is someone standing under the slewing arm and the operator cannot find out in time, it is easy to cause safety accidents and poor safety performance, especially for minors in playgrounds. More people, more potential safety hazards
