Abstract

A material loading device with inbuilt stability for the materials and largely immune to operator error includes a loading frame and at least one first locking mechanism. The loading frame defines a receiving cavity with at least one opening. Opposing inner walls of the loading frame define a plurality of slots. The first locking mechanism, comprising guide rod and first locking portions, is disposed at the opening. The first guide rod is disposed outside the receiving cavity, the first locking portions are movably built into at least one sidewall of the loading frame. The first guide rod will drop by gravity to just outside the loading frame, causing the first locking portions to move and lock the plurality of slots. The first guide rod can also be lifted by a parallel surface, moving the first locking portions away to unlock the slots.

First claim

What is claimed is:

1. A material loading device, comprising:
a loading frame defining a receiving cavity and at least one opening communicating with the receiving cavity, wherein the receiving cavity is configured to receive materials, two opposite inner walls of the loading frame define a plurality of slots; and
at least one first locking mechanism disposed at the at least one opening, each of the at least one first locking mechanism comprising a first guide rod extending along a direction of gravity and a plurality of first locking portions disposed on the first guide rod, wherein the first guide rod is disposed outside the receiving cavity, each of the plurality of first locking portions penetrates, and is capable of moving within, a sidewall of the loading frame, an end of the plurality of first locking portions away from the first guide rod extends along the direction of gravity;
wherein the first guide rod is configured to move along the direction of gravity under an action of gravity to drive the plurality of first locking portions to move and lock the plurality of slots; or, the first guide rod is configured to move in an opposite direction of the direction of gravity to drive the plurality of first locking portions to move away from and unlock the plurality of slots.

2. The material loading device of claim 1 , wherein the loading frame comprises a first side plate, a second side plate, a top plate, and a bottom plate, the first plate is parallel to the second side plate, the bottom plate is opposite to the top plate; the first side plate, the top plate, the second side plate, and the bottom plate are connected to each other in that order to define the receiving cavity and the at least one opening, an inner wall of the first side plate and an inner wall of the second side plate define the plurality of slots and comprise the two opposite inner walls.

3. The material loading device of claim 2 , wherein the at least one first locking mechanism is disposed on the first side plate and/or the second side plate at the at least one opening.

4. The material loading device of claim 2 , wherein each of the plurality of first locking portions comprises a first connecting rod connected to the first guide rod and a first buckle disposed on one end of the first connecting rod away from the first guide rod, the first connecting rod penetrates, and is capable of moving within, the sidewall of the loading frame, the first buckle is disposed inside the receiving cavity, and an end of the first buckle away from the first connecting rod extends along the direction of gravity, the first buckle is configured to move to or move away from one of the plurality of slots to lock or unlock the one of the plurality of slots.

5. The material loading device of claim 4 , wherein along the direction of gravity, a height of a cross-section of the first buckle is larger than or equal to a height of a cross-section of each of the plurality of slots.

6. The material loading device of claim 4 , wherein at least one of the first side plate and the second side plate defines a plurality of first through holes corresponding to the plurality of slots, each of the plurality of first through holes extends along the direction of gravity, the first connecting rod penetrates, and is capable of moving within, one of the plurality of first through holes.

7. The material loading device of claim 6 , wherein along the direction of gravity, each of the plurality of first through holes is located above one of the plurality of slots.

8. The material loading device of claim 4 , wherein the first guide rod is perpendicular to the first buckle.

9. The material loading device of claim 4 , wherein the first guide rod and the first buckle are integrally formed.

10. The material loading device of claim 1 , wherein a bottom end of the first guide rod extends beyond a bottom surface of the loading frame when the plurality of slots is locked.

11. The material loading device of claim 2 , the loading frame defining the at least one opening including two openings, wherein the at least one first locking mechanism is disposed at one of the two openings.

12. The material loading device of claim 11 , the at least one first locking mechanism comprising two first locking mechanisms, wherein the two first locking mechanisms are disposed on the first side plate and the second side plate corresponding to one of the two openings.

13. The material loading device of claim 12 , wherein ends of the plurality of slots at another one of the two openings away from the two first locking mechanisms are sealed.

14. The material loading device of claim 11 , further comprising at least one second locking mechanism disposed at one of the two openings away from the at least one first locking mechanism, wherein the at least one second locking mechanism is a manual locking mechanism, which is configured to manually open and close the one of the two openings away from the at least one first locking mechanism.

15. The material loading device of claim 14 , wherein each of the at least one second locking mechanism comprises a second guide rod extending along the direction of gravity, a plurality of second locking portions disposed on the second guide rod, and a lifting lock disposed on a top end of the second guide rod, the second guide rod is disposed outside the receiving cavity, each of the plurality of second locking portions penetrates, and is capable of moving within, the sidewall of the loading frame, an end of the plurality of second locking portions away from the second guide rod extends along the direction of gravity, the lifting lock is configured to lower the second guide rod, causing the second guide rod moves along the direction of gravity to drive the plurality of second locking portions to move and lock the plurality of slots; or, the lifting lock is configured to lift the second guide rod, causing the second guide rod moves along the opposite direction of the direction of gravity to drive the plurality of second locking portions to move away and unlock the plurality of slots.

16. The material loading device of claim 15 , wherein each of the plurality of second locking portions comprises a second connecting rod connected to the second guide rod and a second buckle disposed on one end of the second connecting rod away from the second guide rod, the second connecting rod penetrates, and is capable of moving within, the sidewall of the loading frame, the second buckle is disposed inside the receiving cavity, and an end of the second buckle away from the second connecting rod extends along the direction of gravity, the second buckle is configured to move to or move away from one of the plurality of slots to lock or unlock the one of the plurality of slots.

17. The material loading device of claim 16 , wherein along the direction of gravity, a height of a cross-section of the second buckle is larger than or equal to a height of a cross-section of each of the plurality of slots.
