Abstract

A material loading device includes a loading frame and at least one first locking mechanism. The loading frame defines a receiving cavity and at least one opening communicating with the receiving cavity. Opposing inner walls of the loading frame define a plurality of first slots. The at least one first locking mechanism is disposed at the at least one opening. The at least one first locking mechanism includes a first locking portion extending downwards. The first locking portion includes a plurality of second slots and a plurality of blocks adjacent to the plurality of second slots. The first locking portion can drop by gravity, driving the plurality of blocks to move to and lock the plurality of first slots. The first locking portion can also be lifted, to drive the plurality of second slots to move to and unlock the plurality of first 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 first slots; and
at least one first locking mechanism disposed at the at least one opening, the at least one first locking mechanism comprising a first locking portion extending along a gravity direction, the first locking portion comprising a plurality of second slots and a plurality of blocks adjacent to the plurality of second slots,
wherein the first locking portion is configured to move along the gravity direction under an action of gravity to drive the plurality of blocks to move to and lock the plurality of first slots; or, the first locking portion is configured to move in an opposite direction of the gravity direction to drive the plurality of second slots to move to and unlock the plurality of first slots,
along the gravity direction, a height of a cross-section of each of the plurality of second slots is larger than or equal to a height of a cross-section of each of the plurality of first slots; a height of a cross-section of each of the plurality of blocks is larger than or equal to the height of the cross-section of each of the plurality of first 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 side 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, the plurality of first slots is defined on the inner walls of the first side plate and the second side plate.

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 3 , wherein the at least one first locking mechanism further comprises a first fixing portion disposed on a top portion of the first side plate and/or a top portion of the second side plate, a first guide rod disposed on the first fixing portion, a second fixing portion disposed on a bottom portion of the first side plate and/or a bottom portion of the second side plate, and a second guide rod disposed at an end of the first locking portion away from the first fixing portion, an end of the first locking portion close to the first fixing portion is sleeved on the first guide rod, the first locking portion is configured to move along the first guide rod, the second guide rod penetrates through the second fixing portion, the second guide rod is configured to move along the gravity direction and the opposite direction of the gravity direction relative to the second fixing portion;
when the plurality of first slots is locked, one end of the second guide rod away from the first locking portion extends out from a bottom surface of the loading frame, when the plurality of first slots is unlocked, the one end of the second guide rod away from the first locking portion is flush with the bottom surface of the loading frame.

5. The material loading device of claim 4 , wherein the at least one first locking mechanism further comprises a first elastic member sleeved on the first guide rod, both ends of the first elastic member respectively abut against the first fixing portion and the first locking portion, when the first locking portion moves in the opposite direction of the gravity direction to unlock the plurality of first slots, the first elastic member is compressed.

6. The material loading device of claim 1 , wherein the first locking portion further comprises a connecting strip, the plurality of blocks is disposed on the connecting strip, a region between adjacent two of the plurality of blocks forms one of the plurality of second slots.

7. The material loading device of claim 1 , wherein the at least one opening comprises two openings, the at least one first locking mechanism is disposed at one of the two openings.

8. The material loading device of claim 7 , 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.

9. The material loading device of claim 8 , wherein the at least one second locking mechanism comprises a second locking portion extending along the gravity direction, a first clamping groove disposed on the loading frame close to the at least one opening, and a second clamping groove disposed on the loading frame away from the at least one opening, the second locking portion is configured to clamp on the first clamping groove or the second clamping groove to lock or unlock the plurality of first slots.

10. The material loading device of claim 9 , wherein the second locking portion comprises a locking rod extending along the gravity direction, a fixing member disposed at one end of the locking rod close to a top of the loading frame, a rotating shaft connected to the fixing member and the loading frame, a second elastic member sleeved on the rotating shaft, and a rotating portion disposed on one end of the locking rod close to a bottom of the loading frame, the rotating portion is rotationally connected to the loading frame, the fixing member is configured to drive the locking rod to rotate around the rotating shaft, thereby making the locking rod snap in the first clamping groove or the second clamping groove to lock or unlock the plurality of first slots.

11. The material loading device of claim 10 , wherein the rotating portion and the locking rod are integrally formed.

12. The material loading device of claim 10 , wherein the rotating portion is U-shaped.

13. The material loading device of claim 10 , wherein the at least one second locking mechanism comprises two second locking mechanisms, the two second locking mechanisms are disposed on the one of the two openings away from the at least one first locking mechanism.

14. The material loading device of claim 1 , further comprising a handle disposed on the loading frame.
