## Abstract

A device includes: a frame; a tray supported by the frame; a measurement device configured to weigh debris loaded on the tray; wherein the tray has a front end and a rear end with a first side and a second side each extending therebetween; wherein the first side has a first protrusion and a second protrusion with a movement member being configured to make the first protrusion follow a first trajectory; a guide is configured to make the second protrusion follow a second trajectory while the first protrusion is moved along said first trajectory; wherein the movement member is configured to act on said first protrusion so as to roto-translate the tray between a first position, wherein the tray is configured to carry debris to be weighted, and a second position wherein the tray is configured to discharge the debris.

## Claims

### Claim 1

A device comprising:
a frame;
a tray supported by said frame;
a measurement device configured to weigh debris loaded on said tray;
wherein the tray has a front end and a rear end;
wherein the tray has a first side and a second side each extending from said front end to said rear end;
wherein said first side has a first protrusion and a second protrusion;
the device further comprising a movement member configured to make the first protrusion follow a first trajectory;
the device further comprising a guide configured to make the second protrusion follow a second trajectory while the first protrusion is moved along said first trajectory;
wherein said movement member is configured to act on said first protrusion so as to roto-translate said tray between a first position, wherein the tray is configured to carry debris to be weighted, and a second position wherein said tray is configured to discharge said debris,
wherein said movement member comprises:
a shaft, rotatably mounted on said frame;
an arm, having a first end mounted on said shaft and a second end hinged to said first protrusion; and
an actuator configured to rotate said shaft around its longitudinal axis.

### Claim 2 (depends on 1)

The device according to claim 1, wherein said first trajectory is defined by at least a portion of a circle.

### Claim 3 (depends on 1)

The device according to claim 1, wherein the second trajectory is curved with concavity facing upwards.

### Claim 4 (depends on 1)

The device according to claim 1, comprising a plate having a slot defining said second trajectory.

### Claim 5 (depends on 1)

The device according to claim 1, wherein said frame comprises a first upright and a second upright, said shaft extending from said first upright to said second upright, said tray extending between said first upright and said second upright.

### Claim 6 (depends on 5)

The device according to claim 5, wherein said actuator is at least partly housed in one of said first and second uprights.

### Claim 7 (depends on 1)

The device according to claim 1, wherein said first trajectory is defined by a trajectory followed by the second end of said arm when said shaft is rotated.

### Claim 8 (depends on 1)

The device according to claim 1, wherein said first protrusion is arranged in a central portion of said first side.

### Claim 9 (depends on 1)

The device according to claim 1, wherein said second protrusion is arranged between said first protrusion and the front end of said tray.

### Claim 10 (depends on 1)

The device according to claim 1, wherein the second protrusion comprises a plug and a wheel rotatably mounted on said plug, said wheel being configured to engage said guide so as to move along said second trajectory.
