Description

Technical area

The present utility model relates to an excavator, in particular an excavator with spray device.

State of the art

As a conventional heavy machine, an excavator can be seen everywhere on construction sites such as buildings, roads or excavation work, etc. An excavator is used primarily for the extraction, dredging and shoveling of heavy objects such as mud or rocks. During operation of an excavator, a lot of dust is generated on the construction sites. This can seriously affect the health of the operators and also brings great inconvenience to passersby and the environment. When relatively dry mud or rock is scooped directly with the excavator bucket of an excavator, this is very laborious. This requires in particular a high energy consumption and heavy wear of the machine. It is known to wet mud and rock pieces prior to shoveling to avoid unwanted formation of dust.

Content of the present utility model

In view of the above-described problems, the object of the present invention is to provide an improved excavator with which at least the aforementioned disadvantages can be alleviated. In particular, it should be an object of the present invention to provide an improved excavator, which can work with low dust and can achieve a lower energy consumption and lower wear of its components in a simple manner.

This object is achieved according to the present invention by an excavator with spray device. Further advantageous embodiments are the subject of the dependent claims.

According to the present invention, there is provided a dredger with a sprayer, wherein the excavator with sprayer can effectively wet the working environment as needed during operation of the dredger to enable low dust operation and energy consumption as well as less wear of its components.

In order to achieve the above object, the present invention provides a digger with a sprayer comprising an excavator bucket, an excavator arm, and a cab. According to the invention, at least one spray line is arranged on the outer surface of the bucket, wherein at least one spray nozzle is arranged at the front end of the respective spray line to spray water or water droplets, wherein the rear end of the respective spray line is connected to a water supply line, the water supply line along the excavator arm extends to a water tank arranged on the excavator, to the water supply line a valve for controlling the water supply of the respective spray nozzle is provided with water, and further a booster pump is connected to the water supply line to increase the water pressure in the water supply line.

According to a further embodiment, the valve is arranged inside the cabin of the excavator.

According to a further embodiment, the total number of spray lines is four, wherein the spray lines are each connected via a multi-way connection to the water supply line.

According to another embodiment, the spray nozzle and the spray line have a threaded connection with each other, so that the spray nozzle can be dismantled.

In particular, the present invention provides the following advantages: When the excavator with spraying device is in operation, the water spraying of the working environment can be carried out first via the spray line and the spray nozzle. At a lower work intensity, the working environment can be wetted by the spray nozzle; This can eliminate or reduce dust contamination. At a higher work intensity, especially when shoveling the hard mud and stone pieces, the spray nozzle can be removed. The water can be sprayed directly to the mud and stone pieces by a worker via the spray line so that they are quickly soaked to reduce the labor of the excavator.

LIST OF FIGURES

1 shows a schematic representation of the combination between the sprayer bucket and the excavator of the excavator according to the present utility model.

Detailed description of preferred embodiments

In the context of figures and embodiments, the present invention is explained in more detail below by way of example.

The excavator with spraying device has an excavator bucket 1 , an excavator arm 5 and a cabin up. As in 1 shown are four spray lines 2 on the upper or outer surface of the bucket 1 arranged, wherein at the front end of each spray line 2 a spray nozzle 21 is arranged, which scatters the water in a nebulized state or in the form of a droplet mist. The rear end is initially with a multi-way connector 3 connected, the rear end then with a water supply line 4 connected is. The multipath connection 3 can on the excavator spoon 1 welded or otherwise secured.

The water supply line 4 extends along the excavator arm 5 to a water tank arranged on the excavator (not shown), wherein on the water supply line 4 a valve is provided. The valve is located in the cab to facilitate operator operation. In order to increase the water pressure, a booster pump is further connected to the water supply line to increase the impact force of the water. The spray nozzle 21 and the spray line 2 are detachably connected to each other via a threaded connection, so that the respective spray nozzle 21 can be removed if necessary.

When the excavator with spraying device is in operation, water spraying of the working environment can first be done via the spray line 2 and the spray nozzle (s) 21 be executed. At a lower work intensity, the working environment can be controlled via the spray nozzle 21 to be wetted; As a result, dust generation can be effectively suppressed or reduced. At a higher work intensity, especially when shoveling hard mud and stone pieces, the spray nozzle 21 be removed. The water is then over the spray line 2 sprayed directly onto the mud and stone pieces so that they can be quickly soaked, which can effectively reduce the load on the excavator and its components.

The above content is a detailed explanation of the present invention in the context of preferred embodiments. However, the present invention is not limited to the specific embodiment described herein. It is intended, therefore, that all changes within the broader spirit and scope of the present invention, as well as equivalent modifications and improvements, also be included within the scope of the present invention as defined by the appended claims.
