Abstract

A bullet collecting robot comprises a bullet collecting device, a travel driving mechanism, and a controller. The bullet collecting device comprises a collection bin including a bullet accommodating cavity and a collection opening in communication with the bullet accommodating cavity, a friction roller provided at the collection opening, and a collection driving member connected with the friction roller. The travel driving mechanism is configured to drive the bullet collecting device to move. The controller is connected in communication with the collection driving member and the travel driving mechanism, and is configured to control the collection driving member and the travel driving mechanism.

Claims

1. A bullet collecting robot, comprising:

a bullet collecting device comprising;

a friction roller provided at the collection opening and configured to rotate freely, wherein a rotation shaft of the friction roller is disposed opposite to and spaced from the collection surface to form a preset gap exists between a peripheral surface of the friction roller and the collection surface;

a collection driving member connected with the friction roller and configured to drive the friction roller to rotate about the rotation shaft; and

a bullet classifying mechanism mounted within the collection bin and configured to separate different types of bullets,

wherein when the bullets are located outside of the friction roller, the friction roller rotates such that the bullets are caught into the collection opening from the preset gap and roll into the bullet accommodating cavity along the collection surface, and

wherein the friction roller comprises an inner tube, the collection driving member being a motor, a rotor of the motor being received within an opening end of the inner tube and fixedly connected with the opening end of the inner tube to cause the inner tube to rotate along with the rotor of the motor;

a travel driving mechanism configured to drive the bullet collecting device to move; and

a controller connected in communication with the collection driving member and the travel driving mechanism, and configured to control the collection driving member and the travel driving mechanism.

2. The bullet collecting robot of claim 1, wherein the friction roller comprises a sponge sleeve fixedly sleeved on the inner tube.

3. The bullet collecting robot of claim 2, wherein the inner tube includes a carbon fiber tube.

4. The bullet collecting robot of claim 1, wherein the collection surface includes a rising slope surface through which the bullets roll into the bullet accommodating cavity.

5. The bullet collecting robot of claim 4, wherein the slope surface includes a flat surface or an arc-shaped surface.

6. The bullet collecting robot of claim 4, wherein the collection bin comprises:

a baseplate,

a protective shield,

two side plates disposed opposite to and spaced from each other and fixedly connected with the baseplate and two opposite sides of the protective shield, respectively, and

an upper cover disposed opposite to the baseplate, one end of the upper cover being connected with one end of the baseplate and another end of the upper cover being connected with the protective shield,

wherein the protective shield and an end of the baseplate that is distal from the upper cover together form the collection opening, and the collection surface is provided on the baseplate.

7. The bullet collecting robot of claim 6, wherein the one end of the upper cover is detachably connected with the one end of the baseplate and the other end of the upper cover is rotatably connected with the protective shield.

8. The bullet collecting robot of claim 6, wherein:

the collection driving member is a first collection driving member fixed on one of the two side plates and configured to drive one end of the friction roller, and

the bullet collecting device further comprises a second collection driving member fixed on another one of the two side plates and configured to drive another end of the friction roller.

9. The bullet collecting robot of claim 1, wherein the bullet classifying mechanism comprises a partition plate mounted at an entrance of the bullet accommodating cavity and including a hollowed filter groove formed on the partition plate.

10. The bullet collecting robot of claim 9, wherein the partition plate is disposed obliquely, allowing the bullets that do not pass through the filter groove to roll along the partition plate.

11. The bullet collecting robot of claim 10, wherein one end of the partition plate close to the entrance of the bullet accommodating cavity includes a bending portion so as to form a V-shaped limiting rib.

12. The bullet collecting robot of claim 1, wherein the bullet classifying mechanism comprises:

a main pipe including a channel with a V-shaped cross section, and

a plurality of branch pipes in communication with the main pipe and corresponding to different widths of the main pipe.

13. The bullet collecting robot of claim 1, wherein the travel driving mechanism comprises two differential driving wheel components disposed opposite to and spaced from each other and provided on two opposite sides of a bottom of the collection bin, respectively.

14. The bullet collecting robot of claim 13, wherein each of the differential driving wheel components comprises a traveling wheel, a wheel axle, and a chassis motor fixedly connected with the traveling wheel through the wheel axle and configured to drive the traveling wheel to rotate.
