Description

  The present invention relates to a dust collection vehicle capable of measuring dust weight.

  In a garbage truck, it is known to support a cargo box via a load cell with respect to a chassis frame in order to measure the weight of dust put into the cargo box. For example, in Patent Document 1, a bent portion that extends in the longitudinal direction of the chassis frame and bends downward in response to the load of the load box is formed between the load box that houses the dust and the chassis frame. In addition, there is described a garbage collection vehicle provided with a bar-type load cell for measuring the weight of dust, in which a strain gauge is provided at the bending portion.

  In this garbage collection vehicle, the load cell is fixed to the upper surface of the chassis frame, the cargo box is supported by the chassis frame through this load cell, and fixed portions that are lower than the upper surface of the bending portion are provided at both ends of the load cell, The fixed portion and the chassis frame are coupled by a fastener that sandwiches and fixes the fixed portion and the chassis frame.

  Further, the fastener has a configuration in which the two screw portions of the U-bolt are passed through the corresponding bolt holes of the flat plate and nuts are applied to both the screw portions so that the fixing portion of the load cell and the chassis frame are sandwiched and tightened. Has been.

  However, in the method of fixing the load cell fixing portion and the chassis frame using U bolts as in the conventional garbage truck, there are many restrictions on the mounting position of the U bolt. That is, since many other components are provided on the chassis frame, the position where the U-bolt can be attached is very limited, and the load cell cannot be attached at any position depending on the size and position of the packing box. There is a problem.

  Therefore, an object of the present invention is to provide a garbage collection vehicle that can increase the degree of freedom of the load cell mounting position in a garbage collection vehicle capable of measuring the weight of dust with a load cell.

  The garbage collection vehicle of the present invention includes a pair of left and right subframes extending along a pair of left and right chassis frames on a pair of left and right chassis frames extending along the vehicle body longitudinal direction on both left and right sides in the vehicle body width direction. Having a pair of left and right base plates provided on each subframe, a cross member connecting the pair of left and right base plates, a load cell provided on each of the pair of left and right base plates, and a load box supported on the load cell It is.

  According to the garbage collection vehicle of the present invention, the load cell that supports the cargo box is fixed on the chassis frame via the pair of left and right base plates respectively provided on the pair of left and right subframes. Here, the pair of left and right subframes extend along the chassis frame on the pair of left and right chassis frames that extend along the vehicle body longitudinal direction on both the left and right sides in the vehicle body width direction. Can be fixed at any position.

  Here, it is desirable that the base plate is disposed in a notch formed in the subframe. As a result, the height of the upper surface of the base plate is lowered by the depth of the notch formed in the subframe, so that the height from the lower surface of the subframe to the upper surface of the load cell provided on the base plate can be reduced. it can.
