Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly to a leveling process for transporting granular raw materials. Background Art

[0002] Currently, the transportation of granular raw materials (such as grain particles, metal particles, etc.) refers to the process of transporting granular materials from one location to another. Since the quantity and weight of granular raw materials are relatively large, generally, factories will build an intelligent hanging transportation system within the factory area for transportation. For example, when granular raw materials arrive, the granular raw materials on the truck are loaded into a transfer box suspended on the system through the intelligent hanging transportation system, and then transported to the stacking area for storage through the transfer box; or when the granular raw materials need to be shipped, the granular raw materials in the stacking area are lifted onto the truck again through the intelligent hanging transportation system, making the transfer and transportation of granular raw materials convenient and fast, and several tons of granular raw materials can be transported at a time, improving the transportation efficiency of granular raw materials.

[0003] Regarding the above related technologies, the inventor believes that when granular raw materials (such as grain particles, metal particles, etc.) are loaded into the transfer box and then transported, due to the loading reason, it often causes the materials on the side of the transfer box close to the feed inlet to be higher than the materials on the side far from the feed inlet after the granular raw materials are loaded into the transfer box. This will result in uneven stacking of the materials in the transfer box, making the center of gravity of the transfer box unstable during hoisting, and thus easily causing the granular raw materials to be unstable during transportation. Summary of the Invention

[0004] In order to solve the problem of improving the instability during the transportation of granular raw materials, the present application provides a leveling process for transporting granular raw materials.

[0005] The present application provides a leveling process for transporting granular raw materials, adopting the following technical solutions:

[0006] A leveling process for transporting granular raw materials includes the following steps:

[0007] Step 1: After docking the transfer box at a position on the hanging guide rail close to the stacking area and / or the unloading area, turn off the power source, temporarily place a cushion block under the bottom of the transfer box to fill the suspended part below the transfer box and keep the transfer box temporarily stable.

[0008] Step 2: Pour the granular raw materials into the transfer box from the upper feed pipe. During the pouring process, check at any time through the first observation window vertically arranged on the side wall of the transfer box and close to the lower part directly below the feed pipe. If it is found from the first observation window that the poured granular raw materials have completely covered the first observation window, it indicates that the amount of granular raw materials poured is sufficient, and at this time, no more granular raw materials are poured into the transfer box.

[0009] Step 3: Then, observe the second observation window vertically provided on the other side wall of the transfer box. The second observation window is parallel to and has the same height as the first observation window. If it is observed that the granular raw materials attached to the inner surface of the second observation window do not completely cover the second observation window, but there is still a part of the upper section of the second observation window left empty, it indicates that at this time, the granular raw materials on the side of the transfer box close to the feed pipe are higher than those on the side far from the feed pipe.

[0010] Step 4: Start the opening and closing mechanism to open the first discharge port provided on the inner bottom wall of the transfer box and below the discharge end of the feed pipe, so that the granular materials accumulated on the side of the transfer box close to the feed pipe enter the bottom transfer cavity provided in the bottom wall of the transfer box through the first discharge port; at the same time, when starting the opening and closing mechanism, the transmission mechanism provided in the bottom wall of the transfer box operates synchronously. After the transmission mechanism operates, the blocking mechanism provided in the inner bottom wall of the transfer box will also be started synchronously and lift vertically by a certain distance from the inner bottom wall of the transfer box, so as to partially vertically block the side of the first discharge port far from the feed pipe in the horizontal direction, so that most of the granular raw materials will vertically fall into the first discharge port from the side piled up close to the feed pipe, and at the same time prevent the granular raw materials on the side far from the feed pipe from tilting down into the first discharge port. Finally, the height of the granular raw materials piled up on the side close to the feed pipe can gradually decrease, while the piled-up height of the granular raw materials on the side far from the feed pipe is not easily affected.

[0011] Step 5: Start the horizontal screw conveyor provided in the bottom transfer cavity to convey the granular raw materials entering the bottom transfer cavity from the side close to the feed pipe to the side far from the feed pipe.

[0012] Step 6: Start the vertical screw conveyor provided in the vertical transfer cavity to vertically lift the granular materials at the vertical connection between the bottom transfer cavity and the vertical transfer cavity to the top of the vertical transfer cavity, and discharge them from the second discharge port and fall on the side of the transfer box far from the feed pipe, so that the granular raw materials piled up on the side close to the feed pipe are finally conveyed to the side far from the feed pipe, that is, the excessive granular raw materials piled up on the side close to the feed pipe are supplemented to the side of the raw material feed pipe.

[0013] Step 7: At the same time, observe the first observation window and the second observation window. If the granular raw materials attached to the inner surface of the second observation window gradually accumulate, the granular raw materials attached to the inner surface of the first observation window gradually decrease, and until the heights of the granular raw materials attached to the first observation window and the second observation window tend to be level, it indicates that the granular raw materials in the transfer box have become stable at this time.

[0014] Step 8: Turn off the horizontal screw conveyor and the vertical screw conveyor, and then drive the opening and closing mechanism to close the first discharge port and at the same time retract the blocking mechanism.

[0066] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0067] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the related objects before and after are in an "or" relationship.

[0068] The following is further illustrated with specific embodiments. Referring to Figures 1 - 9 , the present invention is a process for transporting and leveling granular raw materials, including the following steps:

[0069] Step 1, after docking the transfer box 1 at a position of the suspension guide rail 9 close to the stacking area and / or the unloading area, turn off the power source, temporarily place a cushion block under the bottom of the transfer box 1 so that the suspended part below the transfer box 1 is filled, and keep the transfer box 1 temporarily stable. It should be noted that in the embodiments of this application, the shape of the transfer box 1 is a rectangular body, wherein two opposite side walls and the bottom wall of the transfer box 1 are made with increased thickness, and the other two side walls have normal thickness.

[0070] Step 2, pour the granular raw materials into the upper feed pipe 11 of the transfer box 1. In the embodiments of this application, the feed pipe 11 is inclined and communicated with the side wall of the transfer box 1 close to the top, and the upper inlet of the feed pipe 11 is provided with a flared opening. Exemplarily, a first observation window 12 is vertically arranged on the side wall with normal thickness of the transfer box 1. The first observation window 12 is made of tempered glass, and the position of the first observation window 12 is close to the lower part directly below the feed pipe 11. During the pouring process, check at any time through the first observation window 12. If it is found from the first observation window 12 that the poured granular raw materials have completely covered the first observation window 12, it means that the amount of the poured granular raw materials is sufficient, and at this time, no more granular raw materials are poured into the transfer box 1. If it is found from the first observation window 12 that there is not much height of the poured granular raw materials, pouring can be continued into the transfer box 1 until it is poured to completely cover the first observation window 12.

[0071] Step 3: Then, observe the second observation window 13 vertically provided on the other side wall of the transfer box 1. Exemplarily, the second observation window 13 is also provided on the same side wall with the normal thickness of the transfer box 1. The second observation window 13 is arranged in parallel with and has the same height as the first observation window 12, and the second observation window 13 is arranged away from the first observation window 12. If it is observed that the granular raw materials attached to the inner surface of the second observation window 13 do not completely cover the second observation window 13, but there is still a part of the space left in the upper section of the second observation window 13, it indicates that at this time, the granular raw materials on the side of the transfer box 1 close to the feed pipe 11 are higher than the granular raw materials on the side away from the feed pipe 11, and the granular raw materials inside the transfer box 1 at this time are in an unstable state.

[0072] Step 4: Start the opening and closing mechanism 2 to open the first discharge port 14 provided on the inner bottom wall of the transfer box 1 and below the discharge end of the feed pipe 11, so that the granular materials accumulated on the side of the transfer box 1 close to the feed pipe 11 enter the bottom transfer cavity 15 provided inside the bottom wall of the transfer box 1 through the first discharge port 14. Exemplarily, the opening and closing mechanism 2 is installed at the first discharge port 14 inside the transfer box 1 for opening and / or closing the first discharge port 14. At the same time, when the opening and closing mechanism 2 is started, the transmission mechanism 3 provided inside the bottom wall of the transfer box 1 operates synchronously. After the transmission mechanism 3 operates, the blocking mechanism 4 provided inside the inner bottom wall of the transfer box 1 will also be started synchronously and lift vertically by a certain distance from inside the inner bottom wall of the transfer box 1, so as to partially vertically block the side of the first discharge port 14 away from the feed pipe 11 in the horizontal direction, so that most of the granular raw materials will be vertically discharged downward from the side accumulated close to the feed pipe 11 into the first discharge port 14, and at the same time prevent the granular raw materials on the side away from the feed pipe 11 from being inclined downward into the first discharge port 14, and finally make the height of the granular raw materials accumulated on the side close to the feed pipe 11 gradually decrease, while the accumulated height of the granular raw materials on the side away from the feed pipe 11 is not easily affected. Exemplarily, the opening and closing mechanism 2, the transmission mechanism 3 and the blocking mechanism 4 are transmission structures, that is, during the process of the opening and closing mechanism 2 opening the first discharge port 14, the power will be transmitted to the transmission mechanism 3, and then the transmission mechanism 3 will transmit the power to the blocking mechanism 4, so that the blocking mechanism 4 will also gradually extend from the bottom wall of the transfer box 1 during the process of the first discharge port 14 being opened. Similarly, the blocking mechanism 4 will also gradually contract from the bottom wall of the transfer box 1 during the process of the first discharge port 14 being closed.

[0073] Step 5: Start the horizontal screw conveyor 5 provided inside the bottom transfer cavity 15 to convey the granular raw materials entering the bottom transfer cavity 15 from the side close to the feed pipe 11 to the side away from the feed pipe 11.

[0074] Step Six: Activate the vertical screw conveyor mechanism 6 installed in the vertical transfer cavity 16 to vertically lift the granular material at the vertical communication point between the bottom transfer cavity 15 and the vertical transfer cavity 16 to the top of the vertical transfer cavity 16, and discharge it from the second discharge port 17 and drop it on the side of the transfer box 1 away from the feed pipe 11, so that the granular raw materials piled up on the side close to the feed pipe 11 are finally conveyed to the side away from the feed pipe 11, that is, the excessive granular raw materials piled up on the side close to the feed pipe 11 are supplemented to the side of the raw material feed pipe 11.

[0075] Step Seven: Observe the first observation window 12 and the second observation window 13 simultaneously. If the granular raw materials attached to the inner surface of the second observation window 13 gradually accumulate, the granular raw materials attached to the inner surface of the first observation window 12 gradually decrease, and until the heights of the granular raw materials attached to the first observation window 12 and the second observation window 13 tend to be level, it indicates that the granular raw materials in the transfer box 1 have become stable at this time.

[0076] Step Eight: Turn off the horizontal screw conveyor mechanism 5 and the vertical screw conveyor mechanism 6, and then drive the opening and closing mechanism 2 to close the first discharge port 14 while retracting the flow blocking mechanism 4 at the same time.

[0077] Step Nine: Activate the moving suspension member 8 at the top of the transfer box 1, and move the transfer box 1 along the suspension guide rail 9 to the target position; for example, the moving suspension member 8 and the suspension guide rail 9 are common track moving components in the intelligent suspension transportation system, that is, the transfer box 1 can be suspended by the moving suspension member 8 and moved along the suspension guide rail 9, which will not be elaborated here.

[0078] As Figure 1 、 2 shown, the opening and closing mechanism 2 is installed at the transfer box 1 near the first discharge port 14. For example, in combination with Figure 3 , the opening and closing mechanism 2 includes a rodless electric cylinder 21, a connecting rod 22 and a blocking plate 23; among them, the rodless electric cylinder 21 is horizontally arranged on the outer side wall of the transfer box 1 near its outer bottom wall, that is, the position of the rodless electric cylinder 21 is close to the first discharge port 14. A communication cavity 171 is horizontally opened on the side wall of the transfer box 1 and near the first discharge port 14, and the communication cavity 171 is horizontally communicated with the first discharge port 14. One end of the connecting rod 22 is connected to the moving piston of the rodless electric cylinder 21, and the other end passes through the communication cavity 171 and horizontally extends into the first discharge port 14. The blocking plate 23 is horizontally slidably arranged in the first discharge port 14 and the communication cavity 171. The blocking plate 23 is connected to the end of the connecting rod 22 located in the first discharge port 14, and the plate area of the blocking plate 23 is larger than the opening area of the first discharge port 14.

[0079] Based on the above embodiments, after the rodless electric cylinder 21 is started, the moving piston on the rodless electric cylinder 21 will move. When the moving piston on the rodless electric cylinder 21 moves to the side away from the transfer box 1, the moving piston will drive the connecting rod 22 to move out of the communication cavity 171, and then pull the blocking plate 23 to gradually move from the first discharge port 14 into the communication cavity 171 until the first discharge port 14 is completely opened. When the first discharge port 14 is completely opened, the granular raw materials stored in the transfer box 1 will directly pour into the first discharge port 14 under the action of gravity and finally enter the bottom transfer cavity 15, realizing the transfer of the granular raw materials. It should be noted that in this embodiment, the end of the blocking plate 23 away from the connecting rod 22 is provided with a tip. In this way, when the blocking plate 23 retracts to the position where it blocks the first discharge port 14 again, the tip edge of the blocking plate 23 will not get stuck with the raw material particles, so that the tip edge of the blocking plate 23 can normally abut against the inner wall of one end of the first discharge port 14.

[0080] Combined with Figure 4 , 5 , side cavities 172 are horizontally opened on the inner side walls of the two opposite long sides of the first discharge port 14. The side cavities 172 extend horizontally from the side of the first discharge port 14 to the inner side wall of the communication cavity 171, and the length direction of the side cavities 172 is the same as the length direction of the connecting rod 22; Exemplarily, insertion strips 231 are provided in parallel on both side edges of the blocking plate 23, and the insertion strips 231 are slidably connected to the side cavities 172, that is, the insertion strips 231 can play a supporting role in the horizontal movement of the blocking plate 23 on the first discharge port 14.

[0081] Such as Figure 2 , 6As shown in the figure, the transmission mechanism 3 is installed inside the bottom wall of the transfer box 1. Exemplarily, the transmission mechanism 3 includes a first rack 31, a first rotating rod 32, a first gear 33, a first roller 34, a second rotating rod 35, a second roller 36, a transmission belt 37, and a second gear 38. Among them, the first rack 31 is arranged in parallel on the side of the insertion strip 231 away from the blocking plate 23. A sliding cavity 173 is horizontally opened inside the bottom wall of the transfer box 1. The length direction of the sliding cavity 173 is the same as and communicated with the length direction of the side cavity 172. The first rack 31 slides synchronously with the blocking plate 23 inside the sliding cavity 173. A first rotating cavity 174 is horizontally opened inside the bottom wall of the transfer box 1. The first rotating cavity 174 is vertically communicated with the sliding cavity 173. The first rotating rod 32 is rotatably arranged inside the first rotating cavity 174. The first gear 33 is coaxially arranged at one end of the first rotating rod 32, and the first gear 33 is located inside the sliding cavity 173 and meshes with the first rack 31. When the blocking plate 23 is in the state of blocking the first discharge port 14, the first gear 33 meshes with the end of the first rack 31 away from the flow blocking mechanism 4. The first roller 34 is coaxially arranged at the other end of the first rotating rod 32. A transmission cavity 175 is horizontally opened inside the bottom wall of the transfer box 1. The length direction of the transmission cavity 175 is the same as the length direction of the sliding cavity 173, and the transmission cavity 175 is vertically communicated with the first rotating cavity 174. The first roller 34 is located inside the transmission cavity 175. A second rotating cavity 176 is opened inside the bottom wall of the transfer box 1. The second rotating cavity 176 is parallel to the first rotating cavity 174, and one end of the second rotating cavity 176 is vertically communicated with the transmission cavity 175. The second rotating rod 35 is rotatably arranged inside the second rotating cavity 176. The transmission belt 37 is wound between the first roller 34 and the second roller 36 for synchronously driving the first roller 34 and the second roller 36 to rotate. The second gear 38 is coaxially arranged at the other end of the second rotating rod 35. A receiving cavity 177 is opened inside the bottom wall of the transfer box 1. The receiving cavity 177 is communicated with the other end of the second rotating cavity 176. The second gear 38 is located inside the receiving cavity 177. Exemplarily, when the second gear 38 is driven to rotate, the flow blocking mechanism 4 vertically extends or vertically contracts from inside the bottom wall of the transfer box 1.

[0082] Based on the above embodiment, when the blocking plate 23 is driven to move toward the connecting chamber 171 side, the blocking plate 23 will drive the first rack 31 to move in the sliding chamber 173. During the movement of the first rack 31, the first gear 33 will be driven to rotate. The rotation of the first gear 33 will drive the first roller 34 to rotate. After the first roller 34 rotates, it will drive the second roller 36 to rotate after being transmitted by the transmission belt 37. Since the second roller 36 and the second gear 38 are coaxially connected through the second rotating rod 35, the second gear 38 will also rotate. The rotation of the second gear 38 will control the movement state of the flow blocking mechanism 4, that is, the flow blocking mechanism 4 extends vertically from the bottom wall of the transfer box 1; similarly, when the blocking plate 23 is driven to cover the first discharge port 14 again, the flow blocking mechanism 4 will retract vertically from the bottom wall of the transfer box 1. The purpose of setting the blocking mechanism 4 is that when the blocking mechanism 4 extends vertically upward to the inside of the transfer box 1, the blocking mechanism 4 can partially block the granular raw materials on the side of the first discharge port 14 far away from the feed pipe 11 in the horizontal direction, so that most of the granular raw materials will be vertically discharged downward from the side accumulated near the feed pipe 11 into the first discharge port 14, while preventing the granular raw materials on the side far away from the feed pipe 11 from being inclined downwardly discharged into the first discharge port 14. After such a setting, it can be ensured that most of the granular raw materials entering the first discharge port 14 are granular raw materials on the side close to the feed pipe 11, so that the height of the granular raw materials accumulated on the side close to the feed pipe 11 can gradually decrease, and the accumulation height of the granular raw materials on the side far away from the feed pipe 11 is not easily affected.

[0083] like Figure 3 , 5 As shown, the flow blocking mechanism 4 is installed in the bottom wall of the transfer box 1. Exemplarily, the flow blocking mechanism 4 includes a flow blocking plate 41, a second rack 42 and a tip portion 43; wherein, a telescopic groove 18 is vertically opened in the bottom wall of the transfer box 1 and located on one side of the first discharge port 14, the flow blocking plate 41 is vertically slidably arranged in the telescopic groove 18, and the plate surface of the flow blocking plate 41 is tightly fitted with the inner groove wall of the telescopic groove 18. A vertical groove 411 is provided on the plate surface of the spoiler 41 away from the first discharge port 14, and the second rack 42 is provided in the vertical groove 411, and the tooth thickness of the meshing teeth of the second rack 42 is less than the depth of the vertical groove 411. Furthermore, the accommodating chamber 177 is communicated with the vertical groove 411, and a portion of the tooth surface of the second gear 38 extends from the accommodating chamber 177 into the vertical groove 411 and meshes with the second rack 42; the tip portion 43 is integrally provided at the upper end of the spoiler 41, and is used to push away the granular raw materials when the spoiler 41 moves vertically upward. The end area of ​​the tip portion 43 itself is very small, and in the process of the spoiler 41 being pushed upward, it will not be subject to excessive resistance from the accumulated granular raw materials, and can effectively push the accumulated granular raw materials to both sides of its own path, thereby ensuring that the spoiler 41 can be pushed up vertically normally.

[0084] On this basis, when the second gear 38 rotates, since the second rack 42 in the vertical strip groove 411 meshes with the second gear 38, the second rack 42 will move in the vertical direction. When the second rack 42 moves vertically upward, it will drive the baffle 41 to gradually extend out of the telescopic groove 18 and insert into the piled granular raw materials. After the baffle 41 vertically extends upward into the piled granular raw materials, the granular raw materials on one side of the first discharge port 14 are blocked by the baffle 41, so that only the granular raw materials above the first discharge port 14 can fall vertically. And the granular raw materials above the first discharge port 14 are just the part with a higher piled height. Therefore, after the baffle 41 moves vertically upward, most of the granular raw materials piled directly above the first discharge port 14 can fall down directionally.

[0085] Combined with Figure 3 , 5An isolation mechanism 7 is provided between the inner wall of the transfer box 1 and the baffle plate 41, and the isolation mechanism 7 is used to prevent the granular raw materials in the transfer box 1 from entering the vertical strip groove 411 when the baffle plate 41 moves vertically upward and / or downward; specifically, the isolation mechanism 7 includes a thin steel ruler 71, a moving block 72, a tension spring 73 and a steering wheel 74; wherein the thin steel ruler 71 includes a first ruler portion 711 and a second ruler portion 712, and a through slit 181 and a tension cavity 182 are horizontally opened in the bottom wall of the transfer box 1, and one end of the through slit 181 is aligned with the vertical strip groove 411 The first ruler portion 711 is connected to the stretching cavity 182, and the other end is connected to the stretching cavity 182. One end of the first ruler portion 711 is located in the stretching cavity 182, and the other end horizontally extends through the slit 181 and is connected to the second ruler portion 712. The second ruler portion 712 is tilted and then vertically extends to be connected to the inner top wall of the vertical strip groove 411; illustratively, the lengths of the first ruler portion 711 and the second ruler portion 712 will change accordingly with the position state of the spoiler 41, that is, when the spoiler 41 moves vertically upward, the first ruler portion 711 will gradually become shorter, and the second ruler portion 712 will gradually become longer. Similarly, when When the spoiler 41 moves vertically downward and retracts into the telescopic slot 18, the first ruler 711 will gradually become longer and the second ruler 712 will gradually become shorter; further, the second ruler 712 will completely block the side notch of the vertical strip slot 411, and the inner ruler surface of the second ruler 712 will be in a vertical state and abut against the tooth tip portion of the second rack 42. After such arrangement, when the vertical strip slot 411 follows the spoiler 41 and is inserted into the granular raw material accumulated above the telescopic slot 18, the granular raw material is not easy to enter the vertical strip slot 411 due to the blocking of the second ruler 712. When the accumulated granular raw materials in the groove 411 and on one side of the vertical groove 411 exert an extrusion pressure on the second ruler portion 712, since the inner ruler surface of the second ruler portion 712 is in a vertical state and abuts against the tooth tip portion of the second rack 42, the ruler body portion of the second ruler portion 712 will not be greatly deformed due to being squeezed, so that the portion of the second ruler portion 712 exposed above the bottom wall of the transfer box 1 can always remain in a state of covering the vertical groove 411, thereby enhancing the effect of the second ruler portion 712 on stably covering the vertical groove 411.

[0086] Exemplarily, the moving block 72 is horizontally slidably disposed in the stretching cavity 182, and one end of the first ruler portion 711 away from the second ruler portion 712 is horizontally connected to the moving block 72; one end of the stretching spring 73 is connected to the moving block 72, and the other end is connected to the side wall of the stretching cavity 182 close to the through slot 181. The stretching spring 73 always has a tendency to horizontally push the moving block 72 toward the side away from the through slot 181 so that the first ruler portion 711 is always in a horizontally taut state; the steering wheel 74 is rotatably disposed on the upper slot surface of the through slot 181, and the steering connection portion of the first ruler portion 711 and the second ruler portion 712 is in contact with the steering wheel 74. That is, the setting of the steering wheel 74 can reduce the wear at the connection position of the first ruler portion 711 and the second ruler portion 712, and enable the first ruler portion 711 and the second ruler portion 712 to change the normal extension direction at the position where they are in contact with the steering wheel 74.

[0087] Referring to Figure 7 , 8 , a fitting groove 4111 is circumferentially opened on the outer periphery of the vertical strip groove 411 on the baffle 41. One end of the second ruler portion 712 away from the first ruler portion 711 is connected to the upper groove wall of the fitting groove 4111. The depth of the fitting groove 4111 is matched with the thickness of the second ruler portion 712, and the width of the fitting groove 4111 is the same as the width of the second ruler portion 712; wherein, when the second ruler portion 712 is in the fitting groove 4111, the outer surface of the second ruler portion 712 is flush with the plate surface of the baffle 41. After such a setting, the second ruler portion 712 can normally move vertically upward out of the telescopic groove 18 as the baffle 41 rises vertically, and the second ruler portion 712 is less likely to deform after extending out of the telescopic groove 18, improving the shielding effect of the second ruler portion 712 on the vertical strip groove 411.

[0088] As Figure 2 , 9 shown, the horizontal screw conveyor mechanism 5 includes a first motor 51, a first rotating shaft 52, and a first screw blade 53; wherein, a bottom transfer cavity 15 is horizontally opened in the bottom wall of the transfer box 1, and a first placement cavity 151 is opened in the bottom wall of the transfer box 1 and on one side of the bottom transfer cavity 15. The first motor 51 is installed in the first placement cavity 151; one end of the first rotating shaft 52 is coaxially connected to the output shaft of the first motor 51, and the other end horizontally extends into the bottom transfer cavity 15; the first screw blade 53 is spirally distributed along the length direction of the first rotating shaft 52, and the first discharge port 14 is vertically aligned with one end of the first screw blade 53 close to the first motor 51. Exemplarily, a vertical transfer cavity 16 is vertically opened in the side wall of the transfer box 1. When the first screw blade 53 rotates, the first screw blade 53 horizontally drives the granular raw material entering the bottom transfer cavity 15 toward the direction away from the first motor 51 to the bottom of the vertical transfer cavity 16.

[0089] In a further embodiment, the vertical screw conveyor mechanism 6 includes a second motor 61, a second rotating shaft 62 and a second screw blade 63; wherein, the vertical transfer cavity 16 is vertically communicated with the bottom transfer cavity 15, and a second placement cavity 161 is formed in the side wall of the transfer box 1 and at the upper end of the vertical transfer cavity 16, and the second motor 61 is installed in the second placement cavity 161; one end of the second rotating shaft 62 is coaxially connected to the output shaft of the second motor 61, and the other end extends vertically downward to the inner bottom wall of the vertical transfer cavity 16 and is rotatably connected to the inner bottom wall of the vertical transfer cavity 16; the second screw blade 63 is spirally distributed along the length direction of the second rotating shaft 62, and a second discharge port 17 is formed in the side wall of the vertical transfer cavity 16 near the top. Exemplarily, the width of a circle of blade parts of the second screw blade 63 facing the second discharge port 17 is greater than the width of the remaining blade parts of the second screw blade 63. Further, when the second screw blade 63 rotates, the second screw blade 63 drives the granular raw materials on the bottom wall of the vertical transfer cavity 16 vertically upward to the second discharge port 17 and discharges them.

[0090] Based on the above solution, after the granular raw materials accumulated on one side close to the feed pipe 11 enter the bottom transfer cavity 15 through the first discharge port 14, the first motor 51 is started. At this time, the second screw blade 63 will rotate spirally, driving the granular raw materials falling into the bottom transfer cavity 15 horizontally in the direction away from the first motor 51 to the bottom of the vertical transfer cavity 16; at the same time, the started second motor 61 will drive the second screw blade 63 to rotate, and then drive the granular raw materials on the bottom wall of the vertical transfer cavity 16 vertically upward. Since the width of a circle of blade parts of the second screw blade 63 facing the second discharge port 17 is greater than the width of the remaining blade parts of the second screw blade 63, the granular raw materials driven to the top of the vertical transfer cavity 16 will be thrown to the second discharge port 17 during the rotation of the second screw blade 63, and finally this part of the granular raw materials is discharged to the side of the transfer box 1 far from the feed pipe 11, so that the stacking height of the granular raw materials accumulated on the side close to the feed pipe 11 gradually decreases, and the stacking height of the granular raw materials on the side far from the feed pipe 11 gradually increases.

[0091] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention.
