Therefore, the empty material box recycling and conveying vehicle can realize automatic recycling of empty material boxes, improve working efficiency, save labor cost, and can meet recycling of a plurality of empty material boxes only by one-time positioning and butt joint, so that recycling efficiency is greatly improved.

(2) According to the material empty bin recycling conveying vehicle, the automatic extension and retraction of the movable baffle can be realized through the baffle mechanism, even if the top end of the movable baffle is higher than or lower than the surface of the docking platform, the blocking or release and transfer of the material empty bin entering the docking platform are realized.

(3) According to the empty material bin recycling conveying vehicle, through the specific structure of the baffle driving mechanism, the push rod mechanism is started during operation, the cam follower performs horizontal linear motion under the push-pull action of the push rod mechanism, and meanwhile, the cam follower is matched with the convex block, so that the horizontal linear motion of the cam follower is converted into vertical motion of the movable baffle. Specifically, when the cam follower is pushed by the push-pull mechanism to linearly move towards the direction close to the movable baffle, the cam follower gradually contacts with the convex blocks on the movable baffle after a certain distance, and stops the push-pull mechanism when the cam follower just pushes up the convex blocks, at the moment, the movable baffle is pushed out and moves vertically upwards, the movable baffle stretches out, so that the top end of the movable baffle is higher than the upper surface of the conveying roller, at the moment, materials entering the conveying roller are blocked, and the condition that materials slide down due to external movement is avoided; when the movable baffle is pushed forward or pulled backward continuously, when the movable baffle moves linearly in a direction far away from the movable baffle, after a certain distance of movement, the cam follower just separates from the convex block, the movable baffle is free from external force influence, the movable baffle is retracted vertically downwards under the action of self gravity and the pulling force of the reset elastic piece and falls back to an initial state, namely the top end of the movable baffle is lower than the upper surface of the conveying roller, the material on the conveying roller is not blocked, and the roller is rotated, so that the release and the transfer of the material can be realized. Therefore, by adopting the baffle mechanism, the automatic release and blocking of the materials can be realized by realizing the automatic extension and retraction of the movable baffle.

The process can be used as a state of the movable baffle when the transport vehicle moves after the goods (empty material box) is taken. When the induction plate of the connecting rod is positioned at the second contact, the guide rail is pushed out for a distance under the pushing of the electric push rod, at the moment, the cam follower is just separated from the convex block, the movable baffle is not influenced by external force, the movable baffle is retracted downwards under the action of self gravity and the pulling force of the reset elastic piece and falls back to the initial state, namely the top end of the movable baffle is lower than the upper surface of the conveying roller, at the moment, the material on the conveying roller is not blocked, the roller is rotated, the release and the transfer of the material can be realized, and the process can be used as a unloading point state after the completion of taking goods (empty material boxes). Therefore, the arrangement can accurately realize the extension and retraction movement of the movable baffle, and improve the accuracy of blocking and releasing materials.

(7) According to the empty material bin recycling conveying vehicle, the induction plate is matched with the third contact, so that when the material between the conveying vehicle and the line side material frame is in butt joint, only one movable baffle is needed to be added on the line side material frame, namely, the extending and retracting of the movable baffle on the line side material frame and the conveying vehicle butt joint platform can be realized only by one baffle driving mechanism, and the purpose of blocking and conveying the material is achieved.

In practical application, when the butt joint platform 3 on the delivery wagon is butt-jointed with the delivery roller on the line side material frame, the delivery roller on the line side material frame is provided with a movable baffle, the third contact 28 is close to the movable baffle 12 on the delivery roller 6 on the line side material frame, along the direction far away from the electric push rod, the two cam followers 17 are sequentially arranged on the guide rail 21, one of the cam followers is matched with the convex block 18 of the movable baffle 12 on the delivery wagon, and the other cam follower 17 close to the line side material frame is used for being matched with the convex block of the movable baffle on the line side material frame. Specifically, as shown in fig. 6, when the sensing plate 25 of the connecting rod 20 is located at the third contact 28, it indicates that the electric push rod 19 continues to be pushed out for a certain distance, that is, the guide rail 21 is pushed out for a certain distance under the action of the electric push rod 19, at this time, the cam follower 17 close to the line side frame cooperates with the bump 18 of the movable baffle 12 on the line side frame to perform linkage, and the line side frame is opened to block, so that the empty material box on the line side frame slides down by self gravity and enters the docking platform 3 of the transport vehicle; meanwhile, in this state, the bump 18 on the movable baffle 12 of the upper docking platform 3 of the transport vehicle and the corresponding cam follower 17 are still in a separated state, the movable baffle 12 is not affected by external force, the movable baffle 12 is retracted downwards under the action of self gravity and the tensile force of the reset elastic piece 16, and falls back to the initial state, namely, the top end of the movable baffle 12 is lower than the upper surface of the conveying roller 6, at this time, the material entering the conveying roller 6 is not blocked, at this time, the roller is rotated, the empty material box can be entered into the docking platform 3 of the transport vehicle, and the process can be used as the upper docking platform 3 of the transport vehicle and the empty material box taking state of the docking line side material frame. When the material is in butt joint between the carrier vehicle and the line side material frame, the movable baffle 12 is only required to be added on the line side material frame, and the movable baffle 12 on the line side material frame and the carrier vehicle butt joint platform 3 can be stretched out and retracted only by one set of baffle driving mechanism 13, so that the purposes of blocking and conveying the material are realized.

Example 9

Compared with the technical scheme of the embodiment 1, the empty material box recycling and conveying vehicle can be improved as follows: the surface of said cam 18 facing the direction of the cam follower 17 has a guiding bevel, which arrangement has a guiding effect facilitating the sliding of the cam 18 with the cam follower 17.

Example 10

Compared with the technical scheme of the embodiment 1, the empty material box recycling and conveying vehicle can be improved as follows: the base 2 is internally provided with a double steering wheel structure chassis. Because the AGV chassis is large, the turning radius of the AGV can be reduced by adopting a double steering wheel structure, and the requirement on the width of a channel is reduced; moreover, the transverse moving function of the double steering wheel structure can ensure that the AGV is close to the material rack when in butt joint, and the clamping box possibly caused by a butt joint gap can be effectively avoided. The chassis with the double steering wheel structure belongs to the prior art, and therefore, the description is not repeated.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
