[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] Embodiment 1: This embodiment mainly describes how a weighing and conveying device can achieve uninterrupted weighing and conveying, specifically: like Figure 1-Figure 2 As shown, the present application provides a weighing and conveying device, including a steel frame 1, which is the supporting part of the weighing and conveying device, and provides a stable support for the weighing and conveying operation. A steel plate 5 is fixedly mounted on the steel frame 1 to support the object on the upper end of the steel frame 1; The steel plate 5 is provided with an opening at the center, and a temporary storage bucket 2 is fixedly mounted on the steel plate 5 by a fixing member. The bottom of the temporary storage bucket 2 passes through the opening. The temporary storage bucket 2 is mainly used for temporary storage of materials. Materials that need to be weighed and transported can be temporarily stored in the temporary storage bucket 2. like Figure 2-Figure 4 As shown, a material inlet 21 is provided on the temporary storage barrel 2 to facilitate the material to enter the temporary storage barrel 2, and a material discharge port 22 is provided at the bottom of the temporary storage barrel 2. A material discharge valve 24 for controlling the discharge or temporary storage of the material is installed in the material discharge port 22, and the material discharge valve 24 is opened or closed by electric control; like Figure 5-Figure 7 As shown, a weighing assembly 4 is provided at the bottom of the temporary storage barrel 2, and the weighing assembly 4 is mainly used for weighing the material. At the same time, a lower steel plate (not shown in the figure) is provided in the steel frame 1, and the lower steel plate mainly provides support for the weighing assembly 4; The weighing assembly 4 mainly includes a bearing plate 41 arranged on the lower steel plate. In this embodiment, a driving motor (not shown in the figure) is fixedly installed at the bottom of the bearing plate 41. The bottom of the driving motor is fixedly installed with the lower steel plate. At the same time, a fixed column 7 is installed with a bearing at the center of the bearing plate 41. The output end of the driving motor passes through the bearing plate 41 and is fixedly installed with the fixed column 7, so that when the driving motor is started, it is suitable for driving the fixed column 7 to rotate synchronously. A disc 42 is fixedly mounted on the outer ring of the fixed column 7, and two groups of drainage ports 421 are opened on the disc 42. The drainage ports 421 are used to guide the material from the upper side of the disc 42 to the lower side, and the drainage ports 421 are conical ports, and the opening of the conical ports gradually decreases from large to small as it approaches the driving motor. refer to Figure 5-Figure 6 At the same time, two sets of fixed seats (not shown in the figure) are fixedly installed on the disc 42, and the fixed seats are respectively arranged at the positions of the two sets of drainage ports 421. At the same time, the middle part of the fixed seat is hollow to facilitate the flow of materials, and multiple sets of guide pillars (not shown in the figure) are fixedly installed on the fixed seat; At the same time, a weighing bucket 6 for weighing the material is arranged on the disc 42, and the weighing bucket 6 comprises a connecting disc 62 fixedly mounted on one end of the plurality of guide pillars away from the fixing seat, and a barrel body 61 is fixedly arranged on the upper end of the connecting disc 62, and the barrel body 61 is provided with openings at both the upper and lower ends to facilitate the entry and outflow of the material; A feed port 66 is provided on the barrel body 61 to facilitate the entry of materials into the barrel body 61. At the same time, an opening and closing cylinder 64 is hingedly installed on both sides of the barrel body 61. A sealing plate 65 is hingedly connected to the output end of the opening and closing cylinder 64. The sealing plate 65 is hinged to the barrel body 61 and is semicircular. The two sets of sealing plates 65 are suitable for forming a full circle to seal the bottom of the barrel body 61 to prevent the material from flowing out. In the initial state, the opening and closing cylinder 64 is in a normal state, the sealing plate 65 is placed vertically and in a separated state, and the bottom of the barrel body 61 is in an open state. When the opening and closing cylinder 64 is opened, its output end extends out. Due to the hinged relationship between the sealing plate 65 and the output end of the opening and closing cylinder 64, when the output end extends out, the sealing plate 65 turns ninety degrees and is in a horizontal state to close the bottom of the barrel body 61. At this time, the materials coming through the feed port 66 will be accumulated in the barrel body 61; Continue to refer Figure 6 A weight sensor 63 is fixedly installed on one side of the barrel 61, and a PLC control system is arranged on the outside of the steel frame 1. The PLC control system is electrically connected to the weight sensor 63. The weight sensor 63 is suitable for weighing the material in the barrel 61 and feeding back the weighing result to the PLC control system; like Figure 7As shown, a screw conveyor 3 is provided at the bottom of the disc 42, and the screw conveyor 3 is fixedly connected to the steel frame 1. The screw conveyor 3 is a prior art, which is mainly composed of a group of servo motors, a screw rod fixedly installed on the output end of the servo motor, and a conveying cylinder arranged on the outer ring of the screw rod, and a first opening is provided at the upper end of the conveying cylinder for facilitating the entry of materials into the conveying cylinder, and a second opening is provided at the lower end of the conveying cylinder away from the first opening for facilitating the output of materials. When in use, the servo motor starts to mobilize the screw rod to rotate, and the material entering the conveying cylinder through the first opening moves toward the second opening position driven by the screw rod, and finally flows out through the second opening to realize the spiral conveying of the material. The screw conveyor 3 is a prior art, and will not be described in detail here. In this embodiment, in the initial state, one group of drainage ports 421 on the disc 42 corresponds to the first opening position, and the material is suitable for directly entering the first opening through the drainage port 421, and then the weighing bucket 6 located at this position is directly above the first opening. If the weighing bucket 6 contains weighed material, the staff only needs to control the closing of the opening and closing cylinder 64, and the output end of the opening and closing cylinder 64 retracts, driving the sealing plate 65 to flip, and the sealing plate 65 returns to the vertical position. Due to the effect of gravity, the material in the barrel body 61 will fall directly and enter the first opening through the drainage port 421. At the same time, the weighing barrel 6 corresponds to the discharge port 22 of the temporary storage barrel 2, and the material in the temporary storage barrel 2 is suitable for directly entering the barrel body 61 through the discharge port 22; In summary, at the beginning of weighing and conveying of materials, the staff only needs to inject the materials to be weighed and conveyed through the feed port 21. At this time, the discharge valve 24 in the temporary storage barrel 2 is in an open state, and the materials can flow out directly through the discharge port 22. The materials falling through the discharge port 22 directly fall into the barrel body 61, and the sealing plate 65 is in a closed state at this time. The materials entering the barrel body 61 will gradually accumulate, and the weight of the accumulated materials in the barrel body 61 is detected by the weight sensor 63, thereby realizing the weighing of the materials. When the accumulation of materials in the barrel body 61 reaches the specified weight, the PLC control system controls the discharge valve 24 to close, and the materials in the temporary storage barrel 2 no longer flow to the barrel body 61, but the staff can still inject materials into the temporary storage barrel 2. At this time, the injected materials are temporarily retained in the temporary storage barrel 2; After the material is weighed, the staff controls the opening and closing cylinder 64 to close, and the output end of the opening and closing cylinder 64 retracts, driving the sealing plate 65 to flip 90 degrees. When the sealing plate 65 starts to flip, the material will fall freely, and enter the conveying cylinder through the middle part of the fixed seat, the drainage port 421 and the first opening in turn, and then be transported away through the screw rod, and finally flow out of the screw conveyor 3 through the second opening to realize the transportation of the material; The above is the basic working principle of the material weighing device. In order to achieve uninterrupted material transportation, in this embodiment, the number of barrels 61 is two groups, one group of weighing barrels 6 is located at the upper end of the first opening of the screw conveyor 3, and the other group of barrels 61 is located at the lower end of the discharge port 22. It can be understood that when the weighing of the material in the barrel 61 located at the lower end of the discharge port 22 is completed, it is necessary to control the drive motor to start, drive the fixed column 7 and the disc 42 to rotate, and the two groups of barrels 61 can rotate to replace the barrel 61 at the lower end of the discharge port 22 to the position of the first opening, so as to facilitate the transportation of materials; Thus, in the initial state, the barrel bodies 61 of the two groups of weighing barrels 6 are respectively located at the discharge port 22 position and the first opening position, and the barrel body 61 located at the discharge port 22 position is defined as the first barrel, and the barrel body 61 located at the first opening position is defined as the second barrel. When the weighing and conveying operation starts, the discharge valve 24 in the temporary storage barrel 2 is opened first to convey the material into the first barrel. After the weighing of the material in the first barrel is completed, the staff starts the drive motor to drive the fixed column 7 and the disc 42 to rotate, so that the first barrel and the second barrel located on the disc 42 rotate synchronously, and the positions therebetween are exchanged, and the first barrel rotates to the first opening position. , the second barrel rotates to the discharge port 22 position. At this time, the staff opens the opening and closing cylinder 64 on the first barrel, and the material in the first barrel can be introduced into the screw conveyor 3 for transportation. While the first barrel is transporting the material, the discharge valve 24 is in an open state. At this time, the material in the temporary storage barrel 2 continuously enters the second barrel for weighing the next batch of materials. After the weighing is completed, the material in the first barrel has also been discharged. At this time, the drive motor is controlled to rotate again, and the positions of the first barrel and the second barrel can be exchanged. The first barrel continues to weigh, and the second barrel introduces the weighed logistics into the screw conveyor 3, thereby realizing uninterrupted material weighing and re-transportation.

[0022] Embodiment 2: The above embodiment realizes the replacement of the position of the weighing barrel 6 by driving the disc 42 to rotate by the driving motor, so as to realize the uninterrupted weighing and conveying of the material. However, in the process of weighing and conveying the material, since the material weighing is carried out in multiple batches, a certain amount of operation time is required to complete it. In the case of a long operation, it is difficult to ensure that the state of the material is consistent with the state before weighing. In order to ensure the quality of the material, it is necessary to take a small amount of samples when weighing the material for the convenience of material detection; This embodiment makes improvements to the structure of the weighing assembly 4 on the basis of the above embodiment, specifically: like Figure 4As shown, a sampling port 23 is provided on the other side of the bottom of the temporary storage barrel 2. The diameter of the sampling port 23 is smaller than the diameter of the discharge port 22, and a solenoid valve (not shown in the figure) is provided in the sampling port 23. The opening or closing of the sampling port 23 is controlled by the solenoid valve. When sampling is required, the staff only needs to open the solenoid valve to make the material in the temporary storage barrel 2 flow out from the sampling port 23. The flow rate is lower than the flow rate of the material at the discharge port 22, and too much material will not flow out in a short time. Secondly, different from the first embodiment, the present embodiment no longer controls the rotation of the disc 42 by a driving motor, and the connection between the disc 42 and the fixing column 7 is changed from fixed installation to contact, and the two are only in a mutually fitting relationship; like Figure 7 As shown, ejection cylinders 43 are provided on both sides of the bottom of the carrier plate 41. The bottom of the ejection cylinder 43 is fixedly installed with the lower steel plate. The output end of the ejection cylinder 43 penetrates the carrier plate 41 and extends to the top of the carrier plate 41 to contact the bottom of the disc 42. Therefore, when the ejection cylinder 43 is started, its output end extends out to drive the disc 42 to move up synchronously, but the fixed column 7 remains stationary. It should be noted that a release spring (not shown in the figure) is fixedly installed between the output end of the ejection cylinder 43 and the disc 42. When the ejection cylinder 43 is started and drives the disc 42 to move upward, the force release spring moves upward synchronously. However, when the disc 42 is restricted and cannot move further, the stroke of the ejection cylinder 43 is fixed, so that the output end of the ejection cylinder 43 continues to move upward. At this time, the force release spring is compressed to absorb the thrust of the ejection cylinder 43. On the contrary, when the ejection cylinder 43 drives the disc 42 to move downward, the disc 42 cannot move further downward, and the force release spring is stretched to absorb the retreat force of the telescopic end of the ejection cylinder 43. refer to Figure 8-Figure 9 An arc groove 8 is provided on the surface of the fixed column 7. It should be noted that the arc groove 8 is composed of a plurality of groups of vertical groove bodies and arc groove bodies provided on the surface of the fixed column 7 and connected end to end in sequence. At the same time, an ejector (not shown in the figure) used in conjunction with the arc groove 8 is provided in the disc 42. At the same time, a moving groove (not shown in the figure) for the ejector to move is provided in the disc 42. The ejector includes a fixed end 9 provided in the moving groove. It should be noted that the diameter of the moving groove is slightly larger than the diameter of the fixed end 9, and the fixed end 9 cannot move significantly in the moving groove. The fixed end 9 is fixedly mounted with a ball head 91 on one side close to the arc groove 8. At the same time, the arc groove 8 includes a first channel 81 opened on the surface of the fixed column 7. In the initial state, Fig. 9 , the ball head 91 is located in the first channel 81. For the convenience of description, the position of the ball head 91 at this time is defined as the initial position; A flexible body (not shown in the figure) is fixedly installed at one end of the fixed end 9 away from the ball head 91. The diameter of the flexible body is smaller than the diameter of the fixed end 9 and a mounting step (not shown in the figure) is formed at the connection position. The other end of the flexible body is fixedly installed with the inner wall of the movable groove, so that when the ball head 91 is squeezed, it drives the fixed end 9 to move toward the position of the flexible body, and the flexible body is compressed. At the same time, a squeezing spring 92 is fixedly installed at the mounting step. The other end of the squeezing spring 92 is fixedly installed with the inner wall of the movable groove. Under the action of the squeezing spring 92, in the initial state, the fixed end 9 and the ball head 91 are both in a squeezed state, and the ball head 91 will fit tightly against the inner wall of the first channel 81. like Figure 9-10 As shown, the first channel 81 is a vertical channel, and a second channel 82 is arranged at one end of the first channel 81 away from the initial position. The second channel 82 is an arc-shaped downward channel, and the starting point of the second channel 82 is arranged at the end of the first channel 81, and the end point of the second channel 82 is arranged at a position 180 degrees from the first channel 81 on the fixing column 7, and a third channel 83 identical to the first channel 81 is arranged at the end position of the second channel 82, and the third channel 83 is a channel arranged opposite to the first channel 81 in a direction of 180 degrees; It should be noted that the groove bottom height of the second channel 82 is lower than the groove bottom height of the first channel 81, so that after the ball head 91 slides into the second channel 82 through the first channel 81, it cannot return from the second channel 82 to the first channel 81, and the groove bottom height of the third channel 83 is lower than the groove bottom height of the second channel 82, so that after the ball head 91 slides from the second channel 82 into the third channel 83, it cannot return from the third channel 83 to the second channel 82; For ease of understanding, the position of the first channel 81 can be set as the position of the first barrel, and the position of the third channel 83 is the position of the second barrel. When the material is weighed and transported, the staff first opens the discharge valve 24 to input the material into the first barrel. After the first batch of materials is weighed in the first barrel, the first barrel needs to be switched to the second barrel for discharge. Therefore, the staff starts the ejection cylinder 43, and the output end of the ejection cylinder 43 extends to drive the disc 42 to move upward. The movement of the disc 42 drives the ejection member to move upward synchronously, and the ball head 91 slides in the first channel 81. When the ball head 91 slides to the initial position of the second channel 82 through the first channel 81, due to the limitation of the second channel 82, the ball head 91 can no longer move upward, and then the disc 42 can no longer move upward. The output of the ejection cylinder 43 is resisted and can only be retreated. When the ball head 91 starts to enter the second channel 82, due to the action of the squeezing spring 92, the ball head 91 will still be held in the second channel 82, and when the output end of the ejection cylinder 43 retreats, since the groove bottom position of the second channel 82 is lower than the groove bottom position of the first channel 81, the ball head 91 will not return to the first channel 81, but will continue to slide in the second channel 82. Since the second channel 82 is a downward arc-shaped channel, the ball head 91 will continue to rotate downward and drive the disc 42 to rotate downward synchronously. With the continuous retreat of the output end of the ejection cylinder 43, the ball head 91 moves from the second channel 82 to the third channel 83 and reaches the lowermost end of the third channel 83, which is at the same horizontal height as the initial position. At the same time, the first barrel and the second barrel above the disc 42 are exchanged, and the material weighed in the first barrel begins to be transported, while the second barrel begins to accumulate material for weighing. In this example, in the initial state, there is a certain distance between the weighing barrel 6 and the bottom of the temporary storage barrel 2. When the telescopic end of the ejection cylinder 43 extends to drive the disc 42 to move upward, the disc 42 moves upward to drive the weighing barrel 6 to move upward, and the top of the barrel body 61 will only approach the top of the temporary storage barrel 2 and will not enter the discharge port 22, thereby not affecting the up and down movement of the disc 42. like Figure 10-11 As shown, a fourth channel 84 communicating with the second channel 82 is provided at the end position of the third channel 83. The fourth channel 84 is an opposite channel provided at a position of 180 degrees from the second channel 82, and is also an arc-shaped downward channel. In this embodiment, the groove bottom height of the fourth channel 84 is lower than the groove bottom height of the third channel 83. At the same time, the end of the fourth channel 84 is communicated with the first channel 81, and a transition slope is provided at the connection point. The highest position of the transition slope is higher than the groove bottom position of the first channel 81 and forms a transition step, so that when the ball head 91 is suitable for entering the fourth channel 84 from the third channel 83, it is suitable for returning from the fourth channel 84 to the first channel 81, but when sliding in the first channel 81, it cannot directly enter the fourth channel 84; It can be understood that when it is necessary to control the second barrel to exchange positions with the first barrel, the staff only needs to start the ejection cylinder 43 again, the output end of the ejection cylinder 43 extends to drive the disc 42 to move upward, the disc 42 moves upward to drive the ejection member to move upward, the ball head 91 moves upward synchronously and slides in the third channel 83, the ball head 91 slides into the fourth channel 84 through the third channel 83, when the ball head 91 slides to the position where the third channel 83 and the fourth channel 84 are connected, due to the restriction of the fourth channel 84, the ball head 91 cannot continue to move upward, so that the disc 42 is restricted, and the output end of the ejection cylinder 43 no longer continues to extend; Then, the output end of the ejection cylinder 43 retreats, and the disc 42 moves downward. Since the bottom height of the fourth channel 84 is lower than the bottom height of the third channel 83, when the disc 42 moves downward and drives the ball head 91 to move downward synchronously, the ball head 91 will not return to the third channel 83, but will slide in the fourth channel 84. The ball head 91 rotates and moves downward, and the disc 42 rotates and moves downward at the same time. Finally, the ball head 91 passes through the fourth channel 84 and returns to the first channel 81 and returns to the initial position. At this time, the second barrel also completes the exchange of positions with the first barrel, and this cycle is repeated to achieve uninterrupted weighing and conveying. In order to achieve sampling and testing of materials during weighing and conveying, continue to refer to Figure 9-11 A fifth channel 85 with an arc shape and pointing upward is provided on one side of the first channel 81, and a sixth channel 86 is provided in a direction rotated ninety degrees from the first channel 81, and the other end of the fifth channel 85 is connected to the sixth channel 86. It can be understood that the ball head 91 is suitable for entering the fifth channel 85 from the first channel 81, and then entering the sixth channel 86 through the fifth channel 85; It should be noted that the groove bottom height of the fifth channel 85 is lower than the groove bottom height of the first channel 81, so that after the ball head 91 enters the fifth channel 85 from the first channel 81, it cannot return from the fifth channel 85 to the first channel 81, and the groove bottom height of the sixth channel 86 is lower than the groove bottom height of the fifth channel 85, so that after the ball head 91 enters the sixth channel 86 from the fifth channel 85, it cannot return from the sixth channel 86 to the fifth channel 85; For ease of understanding, the position of the sixth channel 86 can be set to a position corresponding to the sampling port 23. When the ball head 91 enters the sixth channel 86 from the first channel 81 through the fifth channel 85, that is, the disc 42 rotates 90 degrees, the first barrel on the disc 42 rotates from the position of the discharge port 22 to the position of the sampling port 23, so as to facilitate material sampling; Continue to refer Figure 9-10 A seventh channel 87 is provided on one side of the sixth channel 86. The seventh channel 87 is the same as the fifth channel 85 and is also an arc-shaped upward channel. The other end of the seventh channel 87 is connected to the third channel 83, so that the ball head 91 is suitable for entering the seventh channel 87 from the sixth channel 86 and entering the third channel 83 through the seventh channel 87. In this embodiment, the groove bottom height of the seventh channel 87 is lower than the groove bottom height of the sixth channel 86, so that when the ball head 91 enters the seventh channel 87 from the sixth channel 86, it cannot return to the sixth channel 86 from the seventh channel 87; Secondly, a blocking slope is provided at the connection between the seventh channel 87 and the third channel 83. The highest position of the blocking slope is higher than the bottom position of the groove of the third channel 83 and forms a blocking step, so that the ball head 91 is suitable for entering the third channel 83 from the seventh channel 87, but cannot directly enter the seventh channel 87 when sliding in the third channel 83; In order to facilitate the ball head 91 to smoothly enter the fifth channel 85 from the first channel 81, as shown in FIG. Fig. 9 As shown, a first spring piece (not shown in the figure) is arranged in the first channel 81, and the first spring piece is suitable for being controlled to rise or fall by the PLC control system, and the first spring piece is arranged to be inclined, mainly playing a guiding role. In the initial state, the first spring piece is in a lowered state, and the ball head 91 will continue to slide upward when sliding in the first channel 81 normally, and directly enter the second channel 82. When it is necessary to sample the material, the PLC control system controls the first spring piece to rise, and the ball head 91 will reach the position of the first spring piece when sliding in the first channel 81, and the ball head 91 will turn to the first channel 82. And slide into the fifth channel 85 along the edge of the first spring piece, and then enter the sixth channel 86 through the fifth channel 85 until the top position of the sixth channel 86. At this time, the ball head 91 is restricted and cannot continue to move upward, so that the ejection cylinder 43 retreats, driving the ball head 91 to retreat to the bottom position of the sixth channel 86. During this process, the disc 42 rotates 90 degrees, and the first barrel rotates from the initial position of the discharge port 22 to the sampling port 23. At this time, the staff controls the solenoid valve to open, and the material in the temporary storage barrel 2 will enter the first barrel through the sampling port 23; After sampling a certain amount of material, the staff needs to take out the sampled material in the first barrel, and then needs to control the disc 42 to rotate ninety degrees again. In order to facilitate the ball head 91 to enter the seventh channel 87 from the sixth channel 86, a second spring piece similar to the first spring piece is provided in the sixth channel 86 (not shown in the figure). The structure and function of the second spring piece are the same as those of the first spring piece. When the ball head 91 reaches the bottom of the sixth channel 86, the second spring piece will rise. At this time, the ejection cylinder 43 is started again, and the ball head 91 moves up again to contact the second spring piece, and enters the seventh channel 87 under the guidance of the second spring piece, and finally slides in the seventh channel 87 into the third channel 83. When the ball head 91 slides in the seventh channel 87, the ball head 91 continues to rotate upward, and the disc 42 continues to rotate and move upward, and the first barrel rotates from the sampling port 23 to the first opening position, and the second barrel rotates normally to the discharge port 22 position to weigh the next batch of materials. When the material to be tested is taken out of the first barrel, the staff can directly control the opening and closing cylinder 64 on the first barrel to start, drive the sealing plate 65 to flip, and directly take out the material taken out of the first barrel, or after the first barrel is rotated to the first opening position, the obtained material is introduced into the screw conveyor 3, and then it is also possible to lead it out through the screw rod. The method of taking out the material to be tested is not limited here, and the sampling of the material is completed.

[0023] Embodiment 3: The above embodiment realizes sampling of materials while weighing and conveying materials by using the fixed column 7 in conjunction with the ejector on the disc 42. However, during the weighing and conveying process of materials, materials will be accumulated for different periods of time in the temporary storage barrel 2 or the barrel body 61. As the accumulation time of materials increases, some materials may adhere to the inside of the barrel body 61. Secondly, when multiple groups of materials are conveyed, it cannot be guaranteed that each group of materials can be completely introduced into the screw conveyor 3 by gravity. If the materials cannot be completely discharged from the weighing barrel 6, the accuracy of material weighing will be affected. In order to solve this problem, the present embodiment makes improvements to the structure of the barrel 61, specifically: First, different from the above embodiment, reference Figure 6 The connection relationship between the barrel body 61 and the connecting plate 62 is changed from fixed installation to sliding installation. A waist groove 67 is provided on the connecting plate 62 to cooperate with the movement of the barrel body 61. In the initial state, the barrel body 61 is located on one side of the waist groove 67. At the same time, a return spring is fixedly installed between the barrel body 61 and the other side of the waist groove 67. When the barrel body 61 is pushed, the barrel body 61 will slide toward the other side of the waist groove 67, and the return spring will be compressed. When the external force is released, it will be reset due to the force of the return spring; like Figure 12-13 As shown, a convex block (not marked in the figure) is provided at the bottom of the temporary storage barrel 2 near the discharge port 22, and a fixing pin 10 is fixedly installed in the convex block, and one end of the fixing pin 10 protrudes from the convex block to form a convex end. It should be noted that the convex end is located below the discharge port 22 and is on the same vertical plane as one end of the waist groove 67. When the barrel body 61 moves upward toward the discharge port 22, it will contact the fixing pin 10. Secondly, when the weighing barrel 6 rotates with the disc 42, the weighing barrel 6 rotates at a position near the outer ring on the lower side of the temporary storage barrel 2 and does not touch the convex block and the fixing pin 10. When the weighing barrel 6 rotates to the lower side of the discharge port 22, it will contact the fixing pin 10 during the rising process. The upper end surface of the barrel body 61 is provided with an upper inclined surface 611, which is divided into a first inclined surface close to the fixing pin 10, a second inclined surface connected to the first inclined surface, and a third inclined surface connected to the second inclined surface. Fig.13, the first inclined surface can be understood as a conical surface with a small top and a large bottom, and the second inclined surface is an extension surface of the largest outer circle of the first inclined surface, and the third inclined surface is a conical surface with a large top and a small bottom. It can be understood that when the barrel body 61 moves upward, the fixing pin 10 contacts the first inclined surface, and as the barrel body 61 continues to move, the fixing pin 10 produces a squeezing effect on the first inclined surface. Since the fixing pin 10 is kept stationary, the fixing pin 10 generates a reaction force on the barrel body 61 at this time. Under the action of the fixing pin 10, the barrel body 61 moves toward a position away from the fixing pin 10, that is, the barrel body 61 moves toward the other side of the waist groove 67, and then the fixing pin 10 contacts the second inclined surface and the third inclined surface in sequence; When the fixing pin 10 contacts the second inclined surface, the barrel body 61 moves to a position close to the other side of the waist groove 67, and the return spring is subjected to the maximum extrusion force. When the fixing pin 10 contacts the third inclined surface, the barrel body 61 is not extruded, and due to the force of the return spring, the barrel body 61 returns to the initial position. When the barrel 61 moves upward, the fixing pin 10 contacts the first inclined surface, the second inclined surface and the third inclined surface in sequence, and the barrel 61 undergoes a translational reset process. However, when the barrel 61 moves downward, the barrel 61 also undergoes a translational reset process to achieve the effect of shaking the barrel 61. When the ejection cylinder 43 moves too fast, the translational reset process of the barrel 61 will also become faster, and the shaking effect will be better, so as to prevent the materials in the barrel 61 from accumulating for too long and being inconvenient to fall. In order to prevent the shaken-off materials from being lost due to the rapid rotation of the disc 42, continue to refer to Figure 9-11 In this embodiment, the second channel 82 is divided into a continuous first section 821 and a second section 822, wherein the first section 821 is connected to the first channel 81, the second section 822 is connected to the first section 821, and the end of the second section 822 is connected to the third channel 83, and the fourth channel 84 is divided into a third section 841 and a fourth section 842, and the third section 841 and the fourth section 842 have the same functions as the first section 821 and the second section 822, and the first section 821 and the second section 822 are used as examples for illustration; refer to Fig. 9The first section 821 is a section of the channel that is close to being vertically downward with the first channel 81, and the angle between the first section 821 and the first channel 81 is an acute angle of less than 30 degrees. However, the second section 822 is an arc-shaped downward channel that is close to being parallel, and is nearly perpendicular to the first channel 81. It can be understood that when the ball head 91 slides in the first section 821, since it is close to being vertically downward, the disc 42 does not rotate too much when it moves with the ball head 91, but instead moves downward a greater distance. When the ball head 91 slides in the second section 822, due to its Close to parallel, the disc 42 does not move downward too much when moving with the ball head 91, but rotates more, mainly because when the disc 42 moves downward, it will first move downward and then rotate, so that when the barrel 61 moves downward, it will first contact with the fixing pin 10, and with the help of the force of the fixing pin 10 on it, the barrel 61 can be shaken quickly, and the materials accumulated in the barrel 61 can be quickly shaken off. After the ball head 91 passes through the first section 821 and enters the second section 822, the disc 42 mainly rotates to adjust the angle, which is convenient for the replacement of the weighing barrels 6; When the ball head 91 slides in the third section 841, the ball head 91 still moves downward mainly and rotates as an auxiliary, and the barrel body 61 vibrates with the force of the fixing pin 10. When the ball head 91 slides in the fourth section 842, the barrel body 61 rotates mainly and descends as an auxiliary, so that the weighing barrels 6 can be exchanged. In summary, the above mainly realizes the shaking of the barrel body 61 when the barrel body 61 rotates upward or downward through the sliding relationship between the fixing pin 10 and the barrel body 61. This method is only one of many implementation methods and is not limited here. Secondly, the arc groove 8 is improved in sections so that the ball head 91 changes the movement trajectory of the disc 42 when moving in different groove sections, so that the barrel body 61 can stay at the discharge port 22 for a longer time and contact with the fixing pin 10 when moving downward, thereby achieving the effect of shaking the barrel body 61.

[0024] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
