Definitions
- the present invention relates to an earth moving machine of the type commonly known as a “minidumper” or “minitransporter” for loading and transporting materials, in particular building materials such as sand, gravel, etc.
- a generic minidumper normally comprises:
- each bucket operating arm is operated by a respective hydraulic actuator controlled by the operator using said rear control means.
- the dump body can be mounted on a lifting mechanism suitable to raise said body for unloading from a position that is raised with respect to the plane of translation of the drive unit.
- the lifting system is operated by hydraulic cylinders controlled by the operator using said rear control means.
- the purpose of the present invention is thus to overcome the drawbacks described above by providing a minidumper according to the characteristics claimed in Claim 1.
- the general structure of the minidumper 10 according to the present invention is substantially the same as that of the minidumper described in Italian Utility Model No. 0000256106 , by this same applicant, the description of which is to be considered as an integral part of this description.
- the essential difference between the minidumper 10 according to the present invention and that described and claimed in Italian Utility Model No. 0000256106 consists of the fact that instead of an internal combustion engine the present minidumper 10 envisages the use of at least one electric motor (not illustrated) which can be a direct current or alternating current motor. In the case of an alternating current motor the minidumper must be provided with an inverter to control the voltage of said motor. The minidumper must also be provided with a potentiometer to control the revolutions of the motor, a battery charge level indicator and a stop pushbutton that acts directly on the power supply to the motor to stop the latter in case of an emergency.
- the motor is powered by means of batteries.
- the position of the batteries is generally chosen with the aim of increasing the stability of the minidumper especially in the version with the raised unloading function ( Figures 3 , 4 ).
- the centre of gravity of the set of batteries generally lies as close to the ground as possible within the supporting base of the tracks 16, 17 (or of the wheels which are not shown) to prevent it from moving outside said area during operation on sloping terrain.
- a first pair of batteries 101 are arranged beneath the dump body 13
- a second pair of batteries 102 are arranged beneath the motor assembly 19, which, in turn, contains said electric motor (not illustrated).
- the batteries 101, 102 are arranged inside a steel case (not illustrated) that is easily accessible during recharging and to perform routine maintenance on said batteries 101, 102.
- Batteries of a different voltage and/or amperage can be used and connected "in series” and/or “in parallel” to obtain a total voltage or amperage suitable for the installed power and the required duration of electric motor operation.
- the batteries 101, 102 that can be used are of the following types:
- the choice of battery 101, 102 depends on several factors, including:
- a battery charging device (not illustrated) can be fitted to any part of the minidumper 10 provided it is easily accessible by the operator.
- the device can be part of the equipment supplied with the minidumper and left in a specific place where the minidumper is taken for recharging.
- the recharging device When required, the recharging device is connected to the electric power main.
- a first solution envisages a single electric motor that turns the impeller of a pump (not illustrated) belonging to a hydraulic circuit (not illustrated) to power the hydraulic motors (not illustrated) suitable to operate the tracks 16, 17.
- the same pump is also used to operate the lifting mechanism 112 of the body 113 (second embodiment illustrated in Figures 3 , 4 ), to activate the actuator 26 ( Figures 1 , 2 ) for tipping said body 13, and to operate the arms 130, respectively, 230, for tipping the bucket 129, respectively, 229 (see, respectively, the second embodiment illustrated in Figures 3 , 4 and the third embodiment illustrated in Figures 5 , 6 ).
- three electric motors are used, two electric motors to operate the two tracks 16, 17 separately and a third electric motor to turn the impeller of a pump belonging to the hydraulic circuit to power the other lifting and actuating devices.
- the motors for translation may or may not be provided with a reducer as a function of the requested speed of rotation and torque that is required.
- the reducer can be of the axial or angular type.
- An angular reducer is normally used in order to transfer the electric motors (which are usually large) to a position other than the wheel axle and thus increase the clearance below the minidumper.
- the minidumper 10, 100, 200 can be driven by means of geared motors or electric motors, or by means of geared motors or hydraulic motors powered by a pump operated by an electric motor.
- the self-loading system and raised unloading system can be operated directly by means of electric actuators, or by means of hydraulic actuators powered, in any case, by a hydraulic circuit in which the pump is driven by an electric motor.
- the use of the lifting mechanism of the body 213 is not envisaged.
- the minidumper 200 also comprises, in the usual manner, the following components:
- the advantages of the present invention consist of the fact that with the minidumper according to the present invention the noisiness of the vehicle is significantly reduced and the level of pollution generated by the vehicle is practically eliminated especially when used in closed places (dwelling houses, public concerns, industrial warehouses, basements, stables, greenhouses, etc.).
- the minidumper can therefore be used at work-sites located close to houses or offices, places of worship, libraries, places of study, historical town centres or residential areas, in restricted or closed places.
