For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1-Figure 4 As shown, the present embodiment provides a flip-plate baffle linkage mechanism 2 for a sorting trolley 1, and the sorting trolley 1 comprises a mounting frame 11 and a material tray 12, so that when the sorting trolley 1 is traveling, the flip-plate baffle linkage mechanism 2 can prevent the material in the material tray 12 from being thrown out, and when the sorting trolley 1 is unloading, the flip-plate baffle linkage mechanism 2 can enable the material in the material tray 12 to be unloaded smoothly.

[0042] The flap baffle linkage mechanism 2 provided in this embodiment includes an active component 21, a baffle 22 and a driven component 23. The material tray 12 is arranged on the active component 21, and the baffle 22 is provided with a first bracket 221 and a second bracket 222 arranged at an angle. One end of the active component 21 is configured to be hinged to a first fixed point A on the mounting frame 11, and the other end thereof is hinged to a first hinge point C on the first bracket 221. One end of the driven component 23 is configured to be hinged to a second fixed point B on the mounting frame 11, and the other end thereof is hinged to a second hinge point D on the second bracket 222. Among them, the height of the first fixed point A is less than the height of the second fixed point B, and the distance between the first fixed point A and the second fixed point B is L. AB , the distance from the first fixed point A to the first hinge point C is L AC , the distance from the second fixed point B to the second hinge point D is L BD ,and Therefore, when the active component 21 rotates with the first fixed point A as the center, the baffle 22 can rotate around the first hinge point C as the center to block the discharge port of the material tray 12 or allow the material in the material tray 12 to be discharged along the baffle 22. The structure of the flip baffle linkage mechanism 2 is simple and easy to install and maintain.

[0043] like Figure 3 As shown, in this embodiment, the mounting frame 11 includes a first mounting plate 111 and a second mounting plate 112, the second mounting plate 112 is detachably fixed to the first mounting plate 111, the active component 21 is hinged to a first fixing point on the first mounting plate 111, and the driven component 23 is hinged to a second fixing point on the second mounting plate 112. By providing the first mounting plate 111 and the second mounting plate 112, the installation of the flap baffle linkage mechanism 2 can be facilitated.

[0044] In short, Figure 5 As shown, the distance between the first fixed point A and the second fixed point B is L AB , the distance from the first fixed point A to the first hinge point C is L AC , the distance L from the second fixed point B to the second hinge point D BD , since the height of the first fixed point A between the active component 21 and the mounting frame 11 is less than the height of the second fixed point B between the driven component 23 and the mounting frame 11, and Thereby, when the active component 21 rotates around the first fixed point A, the driven component 23 can rotate around the second fixed point B, and the motion trajectory s1 of the first hinge point C and the motion trajectory s2 of the second hinge point D have two intersection points, so that when the active component 21 rotates around the first fixed point A, the driven component 23 can generate a thrust or a pull on the second bracket 222, so that the baffle 22 rotates around the first hinge point C to block the discharge port of the material tray 12 or the baffle 22 rotates around the first hinge point C to not block the discharge port of the material tray 12, that is, the baffle 22 can be automatically opened and closed as needed, and the structure is simple, which is convenient for installation and maintenance.

[0045] Specifically, in this embodiment, if Figure 5 Combination Figure 3 As shown, when the sorting trolley 1 is in the driving state, the material tray 12 is in a horizontal state, the active component 21 and the driven component 23 are both located above the intersection of the track s1 and the track s2, and the driven component 23 generates a rightward thrust on the second bracket 222 of the baffle 22, so that the baffle 22 remains vertically arranged with the bottom of the material tray 12 to prevent the material in the material tray 12 from being thrown out.

[0046] like Figure 5 Combination Figure 4 As shown, when the material in the tray 12 needs to be sorted and unloaded, the active component 21 rotates downward around the first fixed point A, driving the tray 12 and the driven component 23 to rotate downward. When the active component 21 and the driven component 23 rotate to below the intersection of the trajectory s1 and the trajectory s2, the driven component 23 generates a leftward pulling force on the second bracket 222 of the baffle 22, thereby causing the baffle 22 to rotate around the first hinge point C to the side away from the tray 12 until the baffle 22 forms an obtuse angle with the bottom of the tray 12 and the material can slide out along the baffle 22. Similarly, when the material is unloaded and the tray 12 returns to a horizontal state, the active component 21 rotates upward around the first fixed point A, driving the tray 12 and the driven component 23 to rotate upward. When the active component 21 and the driven component 23 rotate to above the intersection of the trajectory s1 and the trajectory s2, the driven component 23 pushes the baffle 22 to rotate around the first hinge point C to be perpendicular to the bottom of the tray 12 to prevent the material in the tray 12 from being thrown out.

[0047] Preferably, the distance L from the first fixed point A to the first hinge point C is AC Less than the distance L from the second fixed point B to the second hinge point D BD , so that the structure of the turnover baffle linkage mechanism 2 is more compact.

[0048] Optionally, in this embodiment, if Figure 5 As shown, the first fixed point A is located at the lower right side of the second fixed point B, or as Figure 6 As shown, the first fixed point A is located at the lower left side of the second fixed point B, or as Figure 7 As shown, the first fixed point A is located directly above the second fixed point B. The three settings can all achieve the cooperation between the active component 21 and the driven component 23 so that the driven component 23 generates a thrust or a pull on the baffle 22, so that the baffle 22 blocks the discharge port of the material tray 12 or keeps the discharge port of the material tray 12 in an open state.

[0049] Furthermore, if Figure 7 As shown, the distance L from the first fixed point A to the second fixed point B AB Greater than the distance L from the first hinge point C to the second hinge point D CD , so that the baffle 22 can be arranged at least 135 degrees with the bottom of the tray 12, so as to facilitate the discharge of materials along the baffle 22. In other embodiments, such as Figure 8 As shown, the distance L from the first fixed point A to the second fixed point B AB It can also be smaller than the distance L from the first hinge point C to the second hinge point D. CD .

[0050] Preferably, the plane where the second bracket 222 is located is located on the extension surface of the baffle 22, so that when the driven component 23 pushes or pulls the second bracket 222 of the baffle 22, the baffle 22 can rotate around the first hinge point C at a larger angle, ensuring that the baffle 22 blocks the discharge port of the material tray 12 or allows the material in the material tray 12 to be discharged along the baffle 22.

[0051] Furthermore, the first bracket 221 is vertically arranged with the baffle 22, which makes the baffle 22 small in size and facilitates the baffle 22 to rotate around the first hinge point C of the first bracket 221. Optionally, the first bracket 221, the second bracket 222 and the baffle 22 are an integrally formed structure.

[0052] Preferably, if Figure 8-Figure 9 As shown, the active component 21 includes a first connecting portion and a second connecting portion which are arranged perpendicular to each other, the first connecting portion is configured to be hinged to the first fixed point A, the second connecting portion is hinged to the first hinge point C, and the material tray 12 is arranged on the second connecting portion so that when the material tray 12 is traveling, the material tray 12 can be in a horizontal state together with the second connecting portion to prevent the material in the material tray 12 from being thrown out.

[0053] Optionally, the second connection portion is configured to be integrally formed with the material tray 12, the first connection portion and the second connection portion are detachably fixedly connected, or the first connection portion and the second connection portion are also integrally formed. Alternatively, the second connection portion is configured to be detachably fixedly connected with the material tray 12, the first connection portion and the second connection portion are integrally formed or detachably fixedly connected, as long as the material tray 12 can move with the movement of the active component 21.

[0054] Preferably, the driven member 23 is a connecting rod structure, so that the structure of the flap baffle linkage mechanism 2 is compact and it is convenient to install it on the mounting frame 11.

[0055] In this embodiment, the first connection part, the second connection part and the material tray 12 are integrally formed, so the movement of the active component 21 is the movement of the material tray 12, eliminating the process step of reinstalling and fixing the material tray 12. In addition, in order to ensure the stability of the movement of the overturning baffle linkage mechanism 2, two first fixed points A are symmetrically arranged on the mounting frame 11 of the sorting trolley 1, and two first connection points are arranged on the first connection part of the active component 21, and each first connection point is hingedly connected to a first fixed point A, so that the active component 21 can stably rotate around the line connecting the two first fixed points A as the center. Two second connection points are arranged on the second connection part of the active component 21, and two first brackets 221 are arranged on the baffle 22, and each second connection point is hingedly connected to a first bracket 221. Furthermore, two second fixed points B are symmetrically arranged on the mounting frame 11 of the sorting trolley 1, two second brackets 222 are arranged on the baffle 22, and the number of driven components 23 is two. One end of each driven component 23 is hinged to a second fixed point B, and the other end is hinged to a second bracket 222, so that the force on the baffle 22 is uniform, so that the baffle 22 can stably rotate around the first hinge point C and the second hinge point D.

[0056] Further, in this embodiment, the first fixed point A is located at the lower right side of the second fixed point B, and the first hinge point C is located at the upper left side of the second hinge point D, that is, the distance L from the first fixed point A to the first hinge point C is AC Less than the distance L from the second fixed point B to the second hinge point D BD .

[0057] The present embodiment further provides a tilting tray sorting machine, comprising a sorting trolley 1 and the above-mentioned tilting tray baffle linkage mechanism 2. By applying the above-mentioned tilting tray baffle linkage mechanism 2, the baffle 22 can be automatically opened and closed as needed, preventing materials from being thrown out while facilitating sorting and unloading.

[0058] In this embodiment, the material tray 12 of the sorting trolley 1 and the active component 21 of the overturning baffle linkage mechanism 2 are integrally formed.

[0059] Furthermore, if Figure 10-11As shown, in order to enable the active component 21 to rotate around the first fixed point A, the tipping tray sorting machine provided in this embodiment also includes a tipping tray device 3, the tipping tray device 3 includes a tipping tray track assembly and a track changing mechanism, the tipping tray track assembly includes a first tipping tray track 31 and a second tipping tray track 32; the track changing mechanism includes a track changing assembly and a fork assembly, one end of the track changing assembly is fixedly arranged on the active component 21, and the other end thereof can move relative to the first tipping tray track 31 and the second tipping tray track 32; the fork assembly is arranged between the first tipping tray track 31 and the second tipping tray track 32, and is used to connect the first tipping tray track 31 and the second tipping tray track 32, so that the other end of the track changing assembly switches between the first tipping tray track 31 and the second tipping tray track 32, so as to drive the active component 21 to rotate. Specifically, when the track changing assembly is located on the first tipping track 31, the active component 21 and the material tray 12 are located in a horizontal position, and the baffle 22 is vertically arranged to the bottom of the material tray 12 to block the material; when the track changing assembly is located on the second tipping track 32, the active component 21 and the material tray 12 are rotated downward to an inclined position, and the baffle 22 is roughly horizontally arranged to the bottom of the material tray 12, so that the material can pour out under the action of gravity.

[0060] In other embodiments, a servo motor may be provided to drive the active component 21 to rotate around the first fixed point A, thereby achieving the above-mentioned effect.

[0061] Optionally, the first flip track 31 is higher than the second flip track 32, the extension direction of the first flip track 31 and the extension direction of the second flip track 32 are arranged in parallel, and the track bottom surface of the first flip track 31 and the track bottom surface of the second flip track 32 form an angle of 90°-180°, preferably 125°-135°, so that the track changing assembly can achieve smooth rotation of the active component 21 during the switching process between the first flip track 31 and the second flip track 32. On the one hand, it is convenient for the material tray 12 to realize material transportation and material unloading; on the other hand, it makes the rotation of the material tray 12 and the active component 21 relative to the mounting frame 11 more stable.

[0062] Preferably, if Fig.11 As shown, in order to enable the track-changing assembly to switch between the first turning plate track 31 and the second turning plate track 32 to rotate the active component 21, the track-changing mechanism includes a track-changing assembly and a fork assembly. Specifically, according to actual needs, multiple track-changing mechanisms are arranged between the first turning plate track 31 and the second turning plate track 32 to enable the material tray 12 to be unloaded at multiple stations.

[0063] Further, one end of the track-changing assembly is fixedly arranged on the lower surface of the active component 21, and the other end thereof can move relative to the first tilting track 31 and the second tilting track 32. The fork assembly is arranged between the first tilting track 31 and the second tilting track 32, and is used to connect the first tilting track 31 and the second tilting track 32, so that the other end of the track-changing assembly is switched between the first tilting track 31 and the second tilting track 32, so as to drive the active component 21 and the material tray 12 to rotate, so that the baffle 22 is rotated relative to the material tray 12 and moved to the baffle 22 to block the discharge port of the material tray 12 or the material in the material tray 12 slides out along the baffle 22 through the tilting baffle linkage mechanism 2.

[0064] Alternatively, if Fig.11 Combination Fig.10 As shown, the track change assembly includes a support rod 33 and a flip wheel 34. One end of the support rod 33 is fixed to the second connection portion of the active component 21, and the other end of the support rod 33 is connected to the flip wheel 34. The flip wheel 34 can move relative to the first flip track 31 and the second flip track 32. The support rod 33 and the flip wheel 34 have a simple structure and occupy a small space. In addition, a support shaft is provided on the other end of the support rod 33, and the flip wheel 34 is rotatably provided on the support shaft to reduce the friction between the flip wheel 34 and the first flip track 31 and the second flip track 32.

[0065] Further, continue as Fig.10 As shown, one end of the support rod 33 connected to the overturn wheel 34 is an inclined surface, and the side surface of the overturn wheel 34 is parallel to the inclined surface. Specifically, the inclined surface structure is: when the active component 21 is in a horizontal position, that is, the overturn wheel 34 is located in the first overturn track 31, the inclined surface is parallel to the bottom surface of the first overturn track 31; when the active component 21 is in a flipping unloading state, that is, the overturn wheel 34 is located in the second overturn track 32, the inclined surface is parallel to the bottom surface of the second overturn track 32.

[0066] Preferably, the tilting wheel 34 is a disc-shaped roller, and the side of the tilting wheel 34 is connected to the support shaft through a bearing. In order to ensure that the sorting trolley 1 remains stable during walking, the tilting wheel 34 can cooperate with the track walls on both sides of the first tilting track 31 to limit the displacement of the tilting wheel 34 in the left and right directions, and avoid the tilting wheel 34 from shaking left and right, thereby ensuring the stability of the active component 21 and the material tray 12. Further, in order to ensure that the shaking of the active component 21 and the material tray 12 is reduced after the material is unloaded, the tilting wheel 34 can also cooperate with the track walls on both sides of the second tilting track 32.

[0067] It should be noted that, in the present embodiment, the flip wheel 34 can cooperate with the two side track walls of the first flip track 31 or the two side track walls of the second flip track 32, which means that the flip wheel 34 is matched with the first flip track 31 and the second flip track 32 with a gap of 0.5mm-2mm, preferably 1mm, to ensure the balance of the active component 21 on the one hand, and to ensure that the flip wheel 34 rolls in the first flip track 31 or the second flip track 32 on the other hand.

[0068] like Fig.11 As shown, in order to achieve the connection and isolation between the first flip track 31 and the second flip track 32, the fork assembly includes a fork seat 35 and a fork rod 36. The two fork seats 35 are arranged between the first flip track 31 and the second flip track 32 to form an inclined slide rail; one end of the fork rod 36 is rotatably connected to one fork seat 35, and the other end thereof can be clamped on the other fork seat 35. When the material tray 12 needs to be flipped over for unloading, the fork rod 36 rotates to connect the inclined slide rail to the first flip track 31 and the second flip track 32, so that when the sorting trolley 1 moves, the flip wheel 34 connected to the active component 21 enters the second flip track 32 along the inclined slide rail, thereby driving the support rod 33 to rotate the active component 21 and the material tray 12 relative to the mounting frame 11, and at the same time, the driven component 23 rotates around the second fixed point B, and pulls the baffle 22 to rotate around the first hinge point C, so that the baffle 22 is in an open state, thereby allowing the material in the material tray 12 to slide out along the baffle 22.

[0069] Furthermore, the fork assembly can be used to move the tipping wheel 34 downward to rotate the active component 21 and the material tray 12 for tipping unloading, and can also move the tipping wheel 34 upward to flip the active component 21 and the material tray 12 to a horizontal position. Specifically, it is sufficient to ensure that the inclination direction of the inclined slide rail is the same as the travel direction of the sorting trolley 1. A fork mechanism is provided at the material loading station for resetting the active component 21 and the material tray 12 to a horizontal loading state, and a fork mechanism is provided at other unloading stations for flipping the active component 21 and the material tray 12 downward for unloading. The structures of the two fork mechanisms are the same, and only the inclination direction of the inclined track formed by the fork seat 35 is different.

[0070] like Fig.10 As shown, in order to ensure that the sorting trolley 1 remains stable during operation and further reduce the size of the sorting trolley 1, the tilting tray sorting machine also includes a first walking track 41 and a second walking track 42 arranged up and down, so that the sorting trolley 1 can move smoothly by only setting the walking track on one side of the sorting trolley 1. In addition, the sorting trolley 1 is driven to move along the first walking track 41 and the second walking track 42 by the walking drive assembly.

[0071] The travel drive assembly includes a motor, a drive wheel and a pressure wheel. The output end of the motor is connected to the drive wheel. The drive wheel and the pressure wheel interact with each other to drive the mounting frame 11 to move along the first travel track 41 and the second travel track 42. Specifically, Figure 10-11 As shown, the mounting frame 11 is provided with a first walking wheel 13 and a second walking wheel 14. The first walking wheel 13 is accommodated in a first walking track 41 and can roll relative to the first walking track 41. The second walking wheel 14 is accommodated in a second walking track 42 and can roll relative to the second walking track 42. The first walking track 41 and the second walking track 42 arranged up and down can enable the sorting trolley 1 to move smoothly.

[0072] Optionally, in order to further ensure the smooth travel of the sorting trolley 1, the mounting frame 11 is also provided with horizontal wheels 15, which can abut and cooperate with the track walls on both sides of the first running track 41 to maintain the balance of the mounting frame 11. Optionally, the horizontal wheels 15 can also abut and cooperate with the track walls on both sides of the second running track 42 to maintain the balance of the mounting frame 11 and make the sorting trolley 1 move smoothly. In other embodiments, the horizontal wheels 15 can also be provided only at the first running track 41, as long as the smooth travel of the sorting trolley 1 can be guaranteed. It should be noted that in this embodiment, the horizontal wheels 15 can cooperate with the track walls on both sides of the first running track 41 or the track walls on both sides of the second running track 42, which means that the horizontal wheels 15 are gap-matched with the first running track 41 and the second running track 42, and the reserved gap is 0.5mm-2mm, preferably 1mm, on the one hand, the balance of the mounting frame 11 is ensured, and on the other hand, the horizontal wheels 15 are ensured to roll in the first running track 41 or the second running track 42.

[0073] Preferably, if Fig.11 As shown, the sorting trolley 1 further includes a transmission plate 16, which is disposed below the mounting frame 11 and can cooperate with the travel drive assembly to enable the travel drive mechanism to drive the transmission plate 16 to move. Specifically, the transmission plate 16 is fin-shaped, and multiple sorting trolleys 1 cooperate with each other through the fin-shaped transmission plate to facilitate power transmission between the sorting trolleys 1.

[0074] The sorting trolley 1 also includes a connecting plate 17. In the present embodiment, the connecting plate 17 is disposed on the lower horizontal wheel 15 and is used to connect two sorting trolleys 1 so that a plurality of sorting trolleys 1 are connected as a whole, so that a plurality of sorting trolleys 1 can be driven to move together by a travel drive assembly.
