The operation of the cargo unloading mechanism 40 is explained below (please refer to fig. 1 to 5 together):
in the invention, the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device can unload goods in four directions; for better explanation, the express sorting trolley 10 which realizes four-way unloading through the universal turnover driving device is specified in four directions, namely front, back, left and right directions; of course, the direction designation of the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device is not unique, and only one direction designation mode is described here;
when the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device is in a loading, moving or idle state (at this time, an initial state), the first cross universal turnover arm 300 and the second cross universal turnover arm 400 are in a folded state, and at this time, the cargo bucket body 421 is fixed on the directional fitting piece 402 and is in a horizontal state; at this time, the four directional locking rods 407 are received in the four locking receiving grooves 405 one to one, and the limiting protrusions 408 are engaged in the limiting grooves 406 one to one; it should be noted that, because the four directional locking rods 407 are received in the four locking receiving grooves 405 one to one, the limiting protrusions 408 are clamped in the limiting grooves 406 one to one, and the limiting protrusions 408 are protruded toward the middle of the bottom of the bucket body 421; thus, the bucket body 421 can be kept in a stable level in the initial state; at this time, the bucket body 421 cannot move in the horizontal direction, so that the displacement does not occur;
if the bucket body 421 has a tendency of shifting toward the front end of the express sorting trolley 10 which realizes four-way unloading through the universal turnover driving device at this time; at this time, after the directional locking rod 407 at the rear end of the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device is combined with the corresponding limiting bump 408, a firm clamping structure is formed with the limiting groove 406, and the cargo bucket body 421 is prevented from moving to the front end of the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device; moreover, it should be further noted that, the clamping structure also limits the cargo bucket body 421 in the left and right directions of the express sorting trolley 10 which realizes four-way unloading through the universal turning driving device, that is, prevents the cargo bucket body 421 from horizontally deflecting in the left and right directions of the express sorting trolley 10 which realizes four-way unloading through the universal turning driving device; namely, the clamping structure simultaneously limits the front direction, the left direction and the right direction of the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device on the bucket body 421;
similarly, at the rear end, the left side and the right side of the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device, the directional locking rod 407 and the corresponding limiting bump 408 are combined and then form the clamping structure with the limiting groove 406; thus, a stable limit is formed on the bucket body 421 in the horizontal direction, so that the bucket body 421 cannot be deviated in the horizontal direction, and the system stability of the express sorting trolley 10 for four-way unloading through the universal overturning driving device is high;
when the goods are transported to the unloading place by the express sorting trolley 10 which realizes four-way unloading through the universal overturning driving device, the express sorting trolley 10 which realizes four-way unloading through the universal overturning driving device needs to automatically unload the goods;
if the loaded boxes are on the left side of the express sorting trolley 10 which realizes four-way unloading through the universal overturning driving device, the express sorting trolley 10 which realizes four-way unloading through the universal overturning driving device needs to be overturned leftwards to unload;
as shown in fig. 4, first, the locking driving motor 403 near the left side of the express sorting cart 10 for four-way unloading by the universal turning driving device drives the corresponding locking slider 404 to slide onto the locking receiving slot 405, so that the locking slider 404 is engaged with the locking receiving slot 405 to lock the directional locking rod 407, so that the directional locking rod 407 cannot be disengaged from the locking receiving slot 405;
then, the turnover driving motor 200 drives the first cross universal turnover arm 300 and the second cross universal turnover arm 400 to extend; the first cross universal overturning arm 300 and the second cross universal overturning arm 400 have a tendency to separate the bucket body 421 from the directional fitting piece 402 during the extension process; as shown in fig. 4, at this time, the locking slide 404 and the locking receiving groove 405 close to the left side of the express sorting trolley 10 for four-way unloading by the universal turning driving device form a locking structure for the directional locking rod 407; therefore, in the process of extending the first cross universal turning arm 300 and the second cross universal turning arm 400, one side of the cargo bucket body 421, which is close to the left side of the express sorting trolley 10 for realizing four-way unloading through the universal turning driving device, is always kept connected with the directional fitting piece 402; thus, along with the extension of the first cross universal turnover arm 300 and the second cross universal turnover arm 400, the cargo bucket body 421 is turned over to the left side of the express sorting trolley 10 which realizes four-way unloading through the universal turning driving device to realize cargo unloading;
after unloading the goods, the overturning driving motor 200 drives the first cross universal overturning arm 300 and the second cross universal overturning arm 400 to fold; thereby resetting the bucket body 421; when the bucket body 421 returns to be fixed on the directional fitting piece 402 and the bucket body 421 is in a horizontal state, the locking driving motor 403 near the left side of the express sorting trolley 10 which realizes four-way unloading through the universal turning driving device drives the corresponding locking slide block 404 to leave from the locking accommodating groove 405, so as to unlock the directional locking rod 407;
similarly, the principle of turning over the front end, the rear end and the right side of the express sorting trolley 10 for realizing four-way unloading through the universal turning driving device is the same as the principle of unloading towards the left side, so the detailed description is omitted;
it should be noted that, when the directional locking rod 407 is locked, the locking driving motors 403 at two ends of the corresponding locking receiving groove 405 drive the locking slider 404 to slide onto the locking receiving groove 405, so as to lock two ends of the directional locking rod 407; the stability of the locking mode is good;
the locking driving motor 403, the locking sliding block 404 and the locking accommodating groove 405 of the directional fitting piece 402 are matched with the directional locking rod 407 of the bucket body 421, so that the turning unloading direction of the express sorting trolley 10 for unloading in four directions is selected through a universal turning driving device;
certainly, when the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device is in an initial state, the locking sliders 404 corresponding to the front end, the rear end, the left side and the right side of the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device slide to the locking accommodating grooves 405, so that the four directional locking rods 407 of the bucket body 421 are locked, the bucket body 421 is further fixed, and the stability of the express sorting trolley 10 for realizing four-way unloading through the universal turnover driving device is further improved; when the express sorting trolley 10 for four-way unloading is turned over and unloaded in any one direction of the front end, the rear end, the left side and the right side by the universal turning driving device, the locking driving motors 403 in the other three directions drive the corresponding locking sliders 404 to leave the corresponding locking accommodating grooves 405, so that the directional locking rods 407 in the other three directions are unlocked, and the direction selection for turning over and unloading the express sorting trolley 10 for four-way unloading by the universal turning driving device is realized.
According to the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device, the overturning direction is selected firstly, then the overturning action is carried out through the universal overturning driving device 430, and the four-way overturning unloading of the express sorting trolley 10 for realizing four-way unloading through the universal overturning driving device is realized.
As shown in fig. 6, in the present invention, four blocking edges 401 are provided around the edge of the tipping bucket 420. Through setting up blocking edge 401, can prevent that the goods on convertible goods fill 420 from taking place to drop at the in-process of transportation, improved the stability to freight. However, in the process of unloading the goods in the turnover type bucket 420 in the turnover type, the blocking edge 401 will block the goods, and the goods cannot be smoothly unloaded due to the blocking of the blocking edge 401. It can be seen that the provision of the blocking edge 401 is twofold. For this reason, the structure of the flip bucket 420 needs to be further optimally designed so that the cargo is not difficult to unload due to the blocking edge 401.
As shown in fig. 6, the flip bucket 420 includes: a bucket body 421, a front end reverse follow-up plate 422, a rear end reverse follow-up plate 423, a left side reverse follow-up plate 424, and a right side reverse follow-up plate 425. The front end turning follow-up plate 422, the rear end turning follow-up plate 423, the left side turning follow-up plate 424 and the right side turning follow-up plate 425 are sequentially arranged on the edges of the front, rear, left and right sides of the bucket body 421. The four side edges of the bucket body 421 are respectively opened with a front through hole 426, a rear through hole 427, a left through hole 428 and a right through hole 429. As shown in fig. 1 and 2, the base 410 is provided with a front jacking block 411, a rear jacking block 412, a left jacking block 413 and a right jacking block 414. The front end lift-up block 411 corresponds to the front end turn-over follow-up plate 422, the rear end lift-up block 412 corresponds to the rear end turn-over follow-up plate 423, the left side lift-up block 413 corresponds to the left side turn-over follow-up plate 424, and the right side lift-up block 414 corresponds to the right side turn-over follow-up plate 425.
The operation of the tipping bucket 420 is explained below (please refer to fig. 1, 2 and 6 together):
when the turnover type cargo bucket 420 is turned over towards the front end, the front end jacking block 411 penetrates through the front end through hole 426 and is pressed on the front end turnover follow-up plate 422, so that the front end turnover follow-up plate 422 is subjected to jacking acting force of the front end jacking block 411, the front end turnover follow-up plate 422 rotates for an angle around the cargo bucket body 421, and the rotated front end turnover follow-up plate 422 fills up the height difference between the cargo bucket body 421 and the blocking edge 401, so that cargo on the cargo bucket body 421 can be unloaded through the front end turnover follow-up plate 422 without being blocked by the blocking edge 401, and the cargo unloading smoothness is improved; when unloading of the goods is finished and the turnover type goods bucket 420 is reset, the front end turnover follow-up plate 422 is separated from the front end jacking block 411, and the front end jacking block 411 does not apply force to the front end turnover follow-up plate 422 any more; at this time, the front end turning follow-up plate 422 performs self-reset under the action of its own gravity, and does not need to additionally arrange a reset mechanism (such as a reset spring and the like) for resetting; the front end turning follow-up plate 422 returns to a state parallel to the corresponding blocking edge 401, so that the front end turning follow-up plate 422 does not influence the loading of goods by the turning type goods bucket 420;
similarly, when the turnover type cargo bucket 420 is turned over towards the rear end, the rear end turning follow-up plate 423 also fills the height difference between the cargo bucket body 421 and the blocking edge 401, so that the cargo can be smoothly unloaded; when the unloading of the goods is finished and the turnover type goods bucket 420 is reset, the rear end turnover follow-up plate 423 automatically resets under the action of the gravity of the rear end turnover follow-up plate 423;
similarly, when the turnover type cargo bucket 420 is turned to the left side, the left turning follow-up plate 424 also fills up the height difference between the cargo bucket body 421 and the blocking edge 401, so that the cargo can be smoothly unloaded; when the unloading of the goods is finished and the turnover type goods bucket 420 is reset, the left turnover follower plate 424 automatically resets under the action of the gravity of the left turnover follower plate 424;
similarly, when the turnover type cargo bucket 420 is turned over to the right, the right turning follow-up plate 425 also fills up the height difference between the cargo bucket body 421 and the blocking edge 401, so that the cargo can be smoothly unloaded; when the unloading of the cargo is completed and the flip bucket 420 is reset, the right flip follower plate 425 resets itself by its own weight.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
