With continued reference to fig. 1 and 4, the sliding assembly includes a sliding rail 31 and a sliding block 32, the sliding rail 31 is disposed on both sides of the storage bin 1, and the sliding blocks 32 are slidably connected in the two sliding rails 31. As shown in fig. 8, two ends of each of the two sliding blocks 32 facing the sliding rail 31 are provided with a roller 33, and the rollers 33 at the two ends of the sliding block 32 are adapted to be embedded into the sliding rail 31 for rolling, so as to limit the sliding block 32 to slide only relative to the sliding rail 31. A connecting rod 34 is also fixedly connected between the two slide rails 31, and the two slide blocks 32 synchronously and synchronously move in the same direction through the connection of the connecting rod 34.

As shown in fig. 3, 6 and 7, the driving member 6 drives the connecting rod 34 to move, so as to drive the two sliding blocks 32 to move along the sliding rail 31. Specifically, the driving member 6 may be an air cylinder, and the end of the piston rod 61 of the driving member 6 is fixedly connected to the connecting rod 34. When the driving member 6 works, the connecting rod 34 is pulled or pushed by the extension of the piston rod 61 to drive the two sliding blocks 32 to slide along the two sliding rails 31. Further, a fixing plate 62 is fixedly connected between the two slide rails 31, the driving element 6 is fixed to one side of the fixing plate 62, and the fixing in the present embodiment can be realized by threading screws.

With reference to fig. 8, two ends of the connecting rod 4 are respectively pivoted to the sliding block 32 and the door 2, and two ends of the two sliding blocks 32 are connected to two ends of two sides of the door 2 through the connecting rod 4. The pivot connection in this embodiment may be implemented by inserting a pin 41 or a rivet to realize the mutual rotation between one end of the connecting rod 4 and the slider 32 and between the other end of the connecting rod 4 and the door 2. When the pin shaft 41 is inserted and pivoted, an outer snap ring (not shown) may be embedded at both ends of the pin shaft 41 to limit the two parts pivoted to each other from being axially separated from the pin shaft 41.

Spacing subassembly includes locating part 51 and spacing round 52, it is rotatable to connect 2 sides of door spacing round 52, locating part 51 is fixed 1 side of feed bin, and with spacing round 52 is located same one side of feed bin 1. The limiting member 51 has a horizontal groove 501 and a vertical groove 502 which are connected with each other, the horizontal groove 501 and the vertical groove 502 are perpendicular to each other, the vertical groove 502 vertically faces the opening 101, the horizontal groove 501 horizontally extends away from one end of the stock bin 1, and the limiting wheel 52 is embedded into the horizontal groove and moves in the vertical groove 502 in a matching manner. Further, the pivot part 21 is fixed at the bottom of the door 2, a pin shaft 41 is simultaneously inserted between the end of the connecting rod 4 and the pivot part 21, and the limiting wheel 52 is connected to the pin shaft 41 to rotate. Furthermore, spacing wheel 52 can be the bearing, round pin axle 41 stretches out the inner circle of connecting rod 4 or the outer one end embedding of pin joint portion 21 and with the welded mode fixed to the bearing is realized with this spacing wheel 52's rotation to adopt the bearing to be favorable to improving spacing wheel 52 rolling frictional force makes the utility model discloses a removal is more smooth and easy.

After the structure is adopted, the utility model discloses the action of during operation as follows:

referring to fig. 3, 7 and 6 in sequence, when the driving element 6 pushes the two sliding blocks 32 to move towards one end of the sliding rail 31 close to the storage bin 1, the connecting rod 4 pushes the limiting wheel 52 to move along the horizontal groove 501, in this process, the connecting rod 4 is limited to be in an inclined state, and the storage bin gate 2 gradually moves towards the opening 101 from one side below the storage bin 1; referring to fig. 6 again, when the limiting wheel 52 moves into the vertical groove 502 and moves upward, the process drives the connecting rod 4 to swing along the gradual vertical groove 502 to form a vertical state, and drives the bin gate 2 to move upward from the opening 101 to be embedded into the opening 101, so as to close the opening 101, and the bin 1 can receive and accumulate filter residues.

Referring to fig. 6, 7 and 3 in sequence, when the driving element 6 pulls the two sliding blocks 32 to move towards one end of the sliding rail 31 far away from the storage bin 1, the connecting rod 4 pulls the limiting wheel 52 to move vertically downwards along the vertical groove 502, in this process, the lower end of the connecting rod 4 gradually swings towards the driving element 6, and the storage bin door 2 moves downwards out of the opening 101; when the limiting wheel 52 moves into the horizontal groove 501 and moves along the horizontal groove 501, the connecting rod 4 is pulled to gradually swing to form an inclined state in the process, and the bin gate 2 is driven to move horizontally at one end, far away from the bin 1, of the sliding rail 31, so that the opening 101 is opened, and filter residues in the bin 1 can fall off.

Can know through above action, the utility model discloses a novel structure passes through driving piece 6 drives sliding assembly removes, realizes driving door 2 removes, the in-process spacing subassembly is right door 2's removal orbit limits. When the opening 101 is specifically closed, the bin door 2 can seal the opening 101 from bottom to top from the bottom of the bin 1, and when the opening is opened, the bin door 2 can move out of the opening 101 from top to bottom and then horizontally move to a position far away from the bin 1, so that the opening and closing mode can effectively avoid the bin door 2 from contacting the bottom surface of the bin 1 in the horizontal moving process, and the friction force generated when the bin door 2 moves into the opening 101 or moves out of the opening 101 is reduced, and the bin door 2 can smoothly open or close the opening 101 of the bin 1.

In addition, as shown in fig. 6, the upward surface of the bin gate 2 is a guide surface 201 inclined downward, and the guide surface 201 is inclined downward and away from one end of the driving member 6. This structure makes after door 2 opens opening 101, the filter residue that remains on door 2 can follow the spigot surface 201 landing downwards avoids remaining.

The aforesaid is only the embodiment of the present invention, but the design concept of the present invention is not limited to this, and it is right to utilize this concept the present invention to perform insubstantial modification, and all belong to infringement the protection scope of the present invention.
