Description

Technical Field

[0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a feeding device and a feeding method for processing a carbendazim suspension. Background Art

[0002] Carbendazim suspension is a highly effective, low-toxic, broad-spectrum and systemic fungicide. Its light brown viscous liquid form makes pressurized filling a common way of loading it. In the existing filling process of carbendazim suspension, it is usually necessary to first move the carbendazim filling bottle to the bottom of the filling tube. Then, the filling tube is driven down by the first drive device so that its filling port can be accurately inserted into the top opening of the carbendazim filling bottle. After that, the second drive device is started to inject the carbendazim suspension in the filling tube into the bottle. After the filling is completed, the capping process is carried out.

[0003] However, this traditional feeding method has some problems. It needs to drive two driving devices in sequence to complete the filling process, which not only increases the number of equipment and increases the cost, but also makes the entire operation process relatively cumbersome. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a feeding device and a feeding method for processing carbendazim suspension, so as to solve the technical problems that the traditional feeding method needs to drive two driving devices in sequence to complete the filling process, requires a large number of equipment, has high cost, and has a relatively cumbersome operation process.

[0005] One of the present inventions: In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is a feeding device for processing carbendazim suspension, comprising a bracket, a filling component and a driving component; Wherein, the filling component comprises a cylinder body with a hollow cylindrical structure, the cylinder body is vertically arranged on the bracket and slides with the bracket along the vertical direction, a piston is arranged inside the cylinder body, the piston and the cylinder body slide and seal, a push rod is arranged between the piston and the bracket, the upper end of the push rod extends into the cylinder body and is connected to the bottom of the piston, and the lower end extends downward and is connected to the bracket, the cylinder body is respectively provided with a discharge port and a feed port, the discharge port is in an open state only at a preset position, and the feed port is provided with a one-way valve, and the one-way valve only allows liquid to flow from the feed port into the cylinder body; The filling component has a first use state and a second use state. In the first use state, the cylinder moves downward, and the push rod pushes the piston to move upward in the cylinder. When the discharge port reaches a preset position, the discharge port is opened, and liquid is transported from the cylinder to the filling bottle through the discharge port. In the second use state, the cylinder moves upward, and the push rod pulls the piston to move downward in the cylinder so that the discharge port leaves the preset position, the discharge port is closed, and the one-way valve is in an open state, and the liquid flows into the cylinder from the feed port. The driving component is arranged on the bracket and is used to drive the cylinder to move up and down, so that the push rod pushes the piston to slide inside the cylinder, thereby switching the filling component between the first use state and the second use state.

[0006] Compared with the prior art, the advantages of the present invention include: (1) The feeding device for processing carbendazim suspension provided by the present invention has a simple structure and is easy to maintain due to the small number of parts.

[0007] (2) The feeding device for processing carbendazim suspension provided by the present invention can realize continuous filling only by driving the driving component alone, thereby saving the number of equipment, reducing costs, and making the entire operation process relatively simple.

[0008] (3) The feeding device for processing carbendazim suspension provided by the present invention realizes automatic switching of the filling component between the first use state and the second use state through the up and down movement of the driving component, thereby improving the degree of automation of the filling process, and continuous filling work is realized through the continuous operation of the driving component, with high efficiency.

[0009] (4) The feeding device for processing carbendazim suspension provided by the present invention has a consistent distance for the driving component to drive the cylinder to move up and down each time, and a consistent distance for the push rod to pull the piston to slide inside the cylinder. Therefore, the pressure change amount caused in the space containing the liquid to be loaded is consistent each time, so the amount of liquid sucked will also be consistent, and the discharge amount will also be consistent, thereby realizing the quantitative filling of the carbendazim suspension.

[0010] (5) The feeding device for processing carbendazim suspension provided by the present invention, during the downward movement of the cylinder, since the discharge port has not reached the preset position (the discharge port is in a closed state) and since the one-way valve of the feed port is in a closed state during this process, the interior of the cylinder is in a closed state, and the upward movement of the piston in the cylinder will cause the space in the cylinder for accommodating the liquid to be filled to be compressed, and its internal pressure will increase. When the discharge port reaches the preset position and opens, the liquid to be filled in the cylinder will be discharged faster, thereby increasing the filling speed of carbendazim, and since the liquid is discharged only after reaching the preset position (aligned with the filling bottle mouth and the discharge end slightly extends into the filling bottle mouth), the liquid splashing waste caused by the discharge end of the discharge port not extending into the filling bottle mouth for liquid discharge will be reduced. At the same time, during the period of time when the piston moves upward to make the discharge port reach the preset position, sufficient time will be provided for the staff to adjust the position of the filling bottle.

[0011] Furthermore, a first tube body is vertically penetrated through the piston, and a first through hole is formed in the first tube body and penetrates the first tube body along the thickness direction of the first tube body, and the first through hole is located on the upper side of the piston; A second tube body is arranged inside the first tube body, and the second tube body is slidably and sealedly matched with the first tube body. The upper end of the second tube body extends upwardly through the first tube body and is fixedly connected to the top of the cylinder body, and the lower end extends downwardly through the lower end of the first tube body and extends out of the cylinder body. The lower end of the second tube body is a discharge port, and the second tube body is provided with a second through hole that penetrates the second tube body along the thickness direction of the second tube body. The first through hole and the second through hole can be overlapped by moving the piston. When the first through hole and the second through hole do not overlap, the first tube body closes the second through hole, and the second tube body closes the first through hole.

[0012] Further, the cylinder is mounted on a mounting frame, and the mounting frame is slidably connected to the bracket along a vertical direction; The driving component includes a disk body and a driving member for driving the disk body to rotate, wherein the driving member is installed on a bracket, the output shaft of the driving member is fixedly connected to the center position of the disk body, the disk body and the mounting frame bracket are provided with a connecting rod, one end of the connecting rod is hinged to the eccentric position of the disk body, and the other end is hinged to the mounting frame.

[0013] Furthermore, the feeding device further comprises a conveying mechanism, and the conveying mechanism has a main shaft; The bracket is provided with a transmission assembly. During the downward movement of the cylinder, the transmission assembly does not drive the main shaft to rotate. During the upward movement of the cylinder, the transmission assembly drives the main shaft to rotate so that the conveying mechanism operates.

[0014] In the present invention: (1) The operation of the conveying mechanism is linked to the up and down movement of the cylinder through the transmission component, making the device highly automated, simplifying the operation process, and reducing the need for manual intervention. The operator only needs to start the entire device to realize the automation of filling and material transmission, reducing labor intensity and improving work efficiency.

[0015] (2) The conveying mechanism and the filling components work well together. When the barrel moves downward for filling, the conveying mechanism remains stationary to avoid possible interference or conflict. When the barrel moves upward to reset, the conveying mechanism starts to operate and prepares the bottles required for the next filling cycle. This design improves the smoothness of the workflow.

[0016] Further, the transmission assembly includes a first gear and a second gear, wherein the first gear is an incomplete gear having only half of the gear teeth, the first gear is meshed with the second gear, the first gear and the second gear are both mounted on a bracket, the first gear is transmission-connected to a driving member, the second gear is coaxially connected to a main shaft, and the driving member can drive the first gear to rotate synchronously so that the second gear rotates intermittently, thereby causing the output mechanism to move intermittently.

[0017] Furthermore, the transmission assembly includes a rack and a third gear, the rack is fixedly connected to the mounting frame, the rack is meshed with the third gear, the third gear is rotatably mounted on the main shaft, and a one-way transmission member is provided between the third gear and the main shaft, the one-way transmission member only allows the third gear to drive the main shaft to rotate when the rack moves upward.

[0018] The second of the present invention: A feeding method for processing carbendazim suspension concentrate, using the above-mentioned feeding device, comprises the following steps: S1. Place multiple filling bottles on the conveying mechanism in sequence with their mouths facing upwards; S2. Start the driving component to move the cylinder upward. As the cylinder moves upward, the push rod pulls the piston to move downward in the cylinder, causing negative pressure to form in the cylinder. At this time, the one-way valve of the feed port opens automatically, allowing the carbendazim suspension liquid to flow into the cylinder from the feed port until the cylinder is filled with the required amount of liquid or reaches the preset liquid level. At the same time, the transmission component drives the main shaft to rotate to operate the conveying mechanism. The conveying mechanism operates to convey the empty filling bottle to the predetermined position. The driving component continues to operate and drives the cylinder to move downward. The push rod then pushes the piston to move upward in the cylinder. When the discharge port reaches the preset position (aligned with the filling bottle mouth and the discharge end slightly extends into the filling bottle mouth), the discharge port opens, and the liquid is transported from the cylinder through the discharge port to the filling bottle. At the same time, the conveying mechanism remains stationary, and the filling bottle placed on the conveying mechanism also remains stationary, so that the discharge port can accurately extend into the filling bottle mouth.

[0027] One of the present inventions: See also Figure 1-7 The present invention provides a technical solution: a feeding device for processing carbendazim suspension, comprising a bracket 1, a filling component and a driving component. The bracket 1 serves as the basic supporting structure of the entire device and is used to fix and support other components.

[0028] See also Figure 1 and 2 The filling component includes a hollow cylindrical structure cylinder 2, which is vertically arranged on the bracket 1 and slides with the bracket 1 in the vertical direction. The inside of the cylinder 2 is used to accommodate the liquid to be filled (in this embodiment, the space between the piston 3 and the top of the cylinder 2 is used to accommodate the liquid to be filled). A piston 3 is arranged inside the cylinder 2, and the piston 3 slides and seals with the cylinder 2. The piston 3 is used to move in the cylinder 2 to control the outflow and inflow of the liquid. A push rod 4 is arranged between the piston 3 and the bracket 1. The upper end of the push rod 4 extends into the cylinder 2 and is connected to the bottom of the piston 3. The lower end extends downward and is connected to the bracket 1. The up and down movement of the push rod 4 drives the piston 3 to slide up and down in the cylinder 2. The cylinder 2 is respectively provided with a discharge port 5 and a feed port 6. The discharge port 5 is only in an open state when it is in a preset position (i.e., aligned with the filling bottle 29 and the discharge end slightly extends into the filling bottle 29). The discharge port 5 is used to transport the liquid from the cylinder 2 to the filling bottle 29. The feed port 6 is provided with a one-way valve 7 , which only allows liquid to flow from the feed port 6 into the interior of the cylinder 2 .

[0029] The filling element has a first usage state and a second usage state.

[0030] See also Figure 6 and 7 In the first use state, the driving component drives the cylinder 2 to move downward, and the push rod 4 pushes the piston 3 to move upward in the cylinder 2 (it should be noted that since the discharge port 5 has not reached the preset position and due to the existence of the one-way valve 7 at the feed port 6, the interior of the cylinder 2 is in a closed state at this time, and the piston 3 moves upward in the cylinder 2, which will cause the space in the cylinder 2 for accommodating the liquid to be filled to be compressed, and its internal pressure will increase). When the discharge port 5 reaches the preset position, the discharge port 5 opens, and the liquid is transported from the cylinder 2 to the filling bottle 29 through the discharge port 5 (since the aforementioned space for accommodating the liquid to be filled is compressed and its internal pressure increases, when the discharge port 5 reaches the preset position and the discharge port 5 opens, the liquid to be filled in the cylinder 2 will be discharged faster).

[0031] See also Figure 1 and 2In the second use state, the cylinder 2 moves upward, and the push rod 4 pulls the piston 3 to move downward in the cylinder 2 so that the discharge port 5 leaves the preset position, the discharge port 5 is closed, and the one-way valve 7 is in an open state, and the liquid flows into the cylinder 2 from the feed port 6 (the space for accommodating the liquid to be loaded is expanded, and its internal pressure is reduced, forming a negative pressure state for sucking the liquid into the cylinder 2). It should be noted that since the driving component drives the cylinder 2 to move upward by the same distance each time, the push rod 4 pulls the piston 3 to slide in the cylinder 2 by the same distance, so the pressure change caused in the space for accommodating the liquid to be loaded is consistent each time, and the amount of liquid sucked will also be consistent.

[0032] The driving component is arranged on the bracket 1 and is used to drive the cylinder 2 to move up and down, so that the push rod 4 pushes the piston 3 to slide inside the cylinder 2, thereby switching the filling component between the first use state and the second use state. The continuous operation of the driving component will realize continuous filling work.

[0033] When in use, the filling bottle 29 is placed at a predetermined position, and the driving component is started to move the cylinder 2 upward. As the cylinder 2 moves upward, the push rod 4 pulls the piston 3 to move downward in the cylinder 2, causing negative pressure to form in the cylinder 2. At this time, the one-way valve 7 of the feed port 6 opens automatically, allowing the carbendazim suspension liquid to flow into the cylinder 2 from the feed port 6 until the cylinder 2 is filled with the required amount of liquid. The driving component continues to operate and drives the cylinder 2 to move downward. As the cylinder 2 moves downward, the push rod 4 pushes the piston 3 to move upward in the cylinder 2. When the discharge port 5 reaches the preset position, the discharge port 5 automatically opens, and the liquid flows from the cylinder 2 through the discharge port 5 into the filling bottle 29, and the cylinder 2 continues to be driven downward until the liquid in the cylinder 2 is completely discharged. The subsequent continued operation of the driving component will cause the filling component to cyclically switch between the first use state and the second use state, thereby realizing continuous filling work.

[0034] See also Figure 1 and 2 In this embodiment: a first tube body 8 vertically penetrates the piston 3, and a first through hole 9 is formed in the first tube body 8 and penetrates the first tube body 8 along the thickness direction of the first tube body 8, and the first through hole 9 is located on the upper side of the piston 3; A second tube body 10 is arranged inside the first tube body 8, and the second tube body 10 and the first tube body 8 are slidably sealed. The upper end of the second tube body 10 extends upward to pass through the first tube body 8 and is fixedly connected to the top of the cylinder 2, and the lower end extends downward to pass through the lower end of the first tube body 8 and extends out of the cylinder 2. The lower end of the second tube body 10 is a discharge port 5. The second tube body 10 is provided with a second through hole 11 that penetrates the second tube body 10 along the thickness direction of the second tube body 10. The first through hole 9 and the second through hole 11 can be overlapped by moving the piston 3. When the first through hole 9 and the second through hole 11 do not overlap, the first tube body 8 closes the second through hole 11, and the second tube body 10 closes the first through hole 9.

[0035] See also Figure 1 and 2 , the driving component drives the cylinder 2 to move downward, and the push rod 4 pushes the piston 3 to move upward. As the piston 3 rises, the first through hole 9 gradually approaches the second through hole 11. When the first through hole 9 and the second through hole 11 overlap, the liquid channel opens, and the liquid flows into the filling bottle 29 through the first through hole 9, the second through hole 11 and the lower end outlet 5 of the second tube 10 under the push of the piston 3. Figure 6 and 7 After the filling is completed, the driving component continues to drive, so that the cylinder 2 moves upward and resets. The piston 3 then drops, the first through hole 9 and the second through hole 11 are completely offset, the first tube 8 closes the second through hole 11 again, and the second tube 10 closes the first through hole 9 to prevent liquid leakage. The one-way valve 7 opens to prepare for the next liquid filling.

[0036] See also Figure 1 and 2 In this embodiment, the cylinder 2 is mounted on the mounting frame 12, and the mounting frame 12 is slidably connected to the bracket 1 along the vertical direction. The up and down sliding of the mounting frame 12 will drive the up and down sliding of the cylinder 2. Specifically, a slide rail 13 arranged along the vertical direction is mounted on the bracket 1, and a slider 14 is slidably matched on the slide rail 13. The slider 14 is fixedly connected to the mounting frame 12 by bolts.

[0037] The driving component includes a disk body 15 and a driving member 16 for driving the disk body 15 to rotate, wherein the driving member 16 is installed on the bracket 1, and the output shaft of the driving member 16 is fixedly connected to the center position of the disk body 15, and the driving member 16 drives the disk body 15 to rotate. The driving member 16 is a mechanical component such as a motor and a pneumatic device that can drive an object to rotate. The disk body 15 and the mounting frame 12 bracket 1 are provided with a connecting rod 17, one end of the connecting rod 17 is hinged to the eccentric position of the disk body 15, and the other end is hinged to the mounting frame 12. Through the connecting rod 17, the rotation of the disk body 15 is converted into the up and down reciprocating motion of the mounting frame 12. The disk body 15 is driven to rotate by the driving member 16, and then the connecting rod 17 is used to convert the rotational motion of the disk body 15 into the up and down sliding of the mounting frame 12 in the vertical direction.

[0038] In addition, the driving component can also be a mechanical component such as an electric push rod 4, a hydraulic push rod 4, etc. that can push an object to move in a straight line. In this case, the driving component is installed on the bracket 1, and the driving end of the driving component is fixedly connected to the mounting frame 12.

[0039] See also Figure 1-9 In this embodiment: the feeding device also includes a conveying mechanism 18, and the filling bottle 29 is placed on the conveying mechanism 18. The conveying mechanism 18 can convey the filling bottle 29 forward when it is operated. The conveying mechanism 18 has a main shaft 19, and the conveying mechanism 18 can be operated by rotating the main shaft 19.

[0040] A transmission assembly is provided on the bracket 1. When the cylinder 2 moves downward for filling, the conveying mechanism 18 remains stationary, and the filling bottle 29 placed on the conveying mechanism 18 also remains stationary, so that the discharge port 5 can accurately penetrate into the filling bottle 29 and implement filling. When the cylinder 2 moves upward to prepare for the next filling, the transmission assembly drives the main shaft 19 to rotate to operate the conveying mechanism 18. The conveying mechanism 18 operates to move the filling bottle 29 that has been filled with carbendazim out of the predetermined position, and conveys the empty filling bottle 29 to the predetermined position for subsequent filling work. Such a cycle realizes the continuous filling and transportation of carbendazim.

[0041] It should be noted that the distance between two adjacent filling bottles 29 should be consistent with the distance that the transmission assembly drives the conveying mechanism 18 to move, so that the bottle mouth of the next filling bottle 29 can face the discharge port 5, thereby reducing the work of manual alignment. Even if there is a slight difference between the distance between adjacent filling bottles 29 and the predetermined distance, only slight adjustments need to be made manually, and there is no need for major adjustments to increase the workload of the staff.

[0042] It is understandable that the conveying mechanism 18 can be a belt-type conveying mechanism 18, a roller-type conveying mechanism 18, or other conveying mechanisms 18 that realize the conveying function by rotating the main shaft 19.

[0043] See also Figure 3-6 In this embodiment: the transmission assembly includes a first gear 20 and a second gear 21, wherein the first gear 20 is an incomplete gear having only half of the gear teeth, which means that the gear teeth of the first gear 20 do not cover the entire circumference, but only occupy a part of the circumference, specifically half of the circumference. When the first gear 20 is meshed with the second gear, it can only transmit in the toothed part. In the toothless arc part, the first gear and the second gear will not mesh, thereby realizing intermittent transmission.

[0044] The first gear 20 meshes with the second gear 21, and both the first gear 20 and the second gear 21 are mounted on the bracket 1, and the first gear 20 is in transmission connection with the driving member 16. Specifically, a first transmission wheel 22 is mounted on the output shaft of the driving member 16, and the first gear 20 is coaxially connected with the second transmission wheel 23, and the first transmission wheel 22 and the second transmission wheel 23 are in transmission connection. More specifically, the transmission connection between the first transmission wheel 22 and the second transmission wheel 23 can be a chain type, a belt type, or the like. The second gear 21 is coaxially connected with the main shaft 19, and the rotation of the second gear 21 will synchronously drive the main shaft 19 to rotate.

[0045] When the driving member 16 is started, it drives the first gear 20 to rotate synchronously. Since the first gear 20 is an incomplete gear with only half of the gear teeth, it can only mesh with the second gear 21 within a specific angle range. When the toothed portion of the first gear 20 meshes with the second gear 21, the second gear 21 will rotate with the first gear 20. When the toothless portion of the first gear 20 rotates to a position opposite to the second gear 21, the two will no longer mesh, and the second gear 21 will stop rotating. As the first gear 20 continues to rotate, this process of engagement and disengagement will be repeated periodically, thereby achieving intermittent rotation of the second gear 21. During this period, the rotation of the second gear 21 will synchronously drive the main shaft 19 to rotate, achieving intermittent rotation of the main shaft 19, thereby achieving intermittent conveying of the conveying mechanism 18.

[0046] It should be noted that during the downward movement of the cylinder 2 (i.e., the filling process), the toothless part of the first gear 20 rotates to a position opposite to the second gear 21, and the conveying mechanism 18 does not operate so that the filling bottle 29 is relatively stationary; during the upward movement of the cylinder 2 (i.e., the process of absorbing the carbendazim suspension into the cylinder 2), the toothed part of the first gear 20 rotates to a position opposite to the second gear 21, and the conveying mechanism 18 operates to convey the filling bottle 29. In addition, the first gear 20 needs to be rotated, and its toothed part drives the second gear 21 to rotate so that the distance of the conveying mechanism 18 is consistent with the distance between two adjacent filling bottles 29. This can be achieved by adjusting the diameters of the second gear 21 and the first gear 20.

[0047] See also Figure 8 and 9In other embodiments: the transmission assembly includes a rack 24 and a third gear 25, the rack 24 is fixedly connected to the mounting frame 12, and the up and down movement of the mounting frame 12 can drive the rack 24 to move up and down synchronously. The rack 24 is meshed with the third gear 25, and the up and down movement of the rack 24 will cause the third gear 25 to rotate in different directions. The third gear 25 is rotatably mounted on the main shaft 19, and the main shaft 19 passes through the bracket 1 and is fixedly connected to the third gear 25. A one-way transmission member is provided between the third gear 25 and the main shaft 19, and the one-way transmission member only allows the third gear 25 to drive the main shaft 19 to rotate during the upward movement of the rack 24. The function of the one-way transmission member (such as a one-way clutch or a ratchet mechanism) is to allow torque to be transmitted only in a specific direction (in this embodiment, the upward movement of the rack 24).

[0048] When the rack 24 moves upward, it meshes with the third gear 25 and drives the third gear 25 to rotate. Due to the effect of the one-way transmission member, the rotation of the third gear 25 will drive the main shaft 19 to rotate synchronously, and the conveying mechanism 18 will operate; when the rack 24 moves downward, although it still meshes with the third gear 25, the one-way transmission member will prevent the rotation of the third gear 25 from being transmitted to the main shaft 19. Therefore, during the downward movement of the rack 24, the main shaft 19 will remain stationary and the conveying mechanism 18 will not operate.

[0049] See also Fig. 9 Specifically, the one-way transmission member includes a first sleeve 26 and a second sleeve 27, both of which are sleeved on the main shaft 19, the first sleeve 26 is coaxially fixedly connected to the third gear 25, and the second sleeve 27 is coaxially fixedly connected to the main shaft 19, and the first sleeve 26 and the second sleeve 27 are respectively provided with mutually meshing first and second locking teeth on opposite sides of the first sleeve 26 and the second sleeve 27, and the first and second locking teeth are both inclined. It should be noted that the inclination direction of the first and second locking teeth is compatible with the movement direction of the rack 24 (that is, the one-way transmission member only works when the rack 24 moves upward). The main shaft 19 is sleeved with a spring 28, and the spring 28 is located between the third gear 25 and the bracket 1, and one end of the spring 28 is fixedly connected to the third gear 25, and the other end abuts against the bracket 1.

[0050] During the downward movement of the cylinder 2, the driving member 16 drives the mounting frame 12 to move downward, thereby driving the rack 24 to move downward. During the downward movement, the rack 24 drives the third gear 25 to rotate. The rotation of the third gear 25 drives the first sleeve 26 to rotate. The first sleeve 26 drives the second sleeve 27 to rotate (the first locking tooth and the second locking tooth are in meshing state and keep in close contact under the action of the spring). The second sleeve 27 drives the main shaft 19 to rotate. The rotation of the main shaft 19 enables the conveying mechanism 18 to operate. During the upward movement of the cylinder 2, the driving member 16 drives the mounting frame 12 to move upward, thereby driving the rack 24 Move upward, the rack 24 drives the third gear 25 to rotate during the upward movement, and the rotation of the third gear 25 drives the first sleeve 26 to rotate, and the first sleeve 26 does not drive the second sleeve 27 to rotate (the first locking tooth and the second locking tooth are periodically meshed, and the rotation of the first sleeve 26 will cause the first locking tooth to disengage from the second locking tooth along the inclined surface and thus do not drive the second sleeve 27 to rotate, and then re-engage under the action of the spring 28, so that the first locking tooth and the second locking tooth are periodically meshed in this cycle, and the second sleeve 27 does not rotate during this process), and thus the main shaft 19 does not rotate, and the conveying mechanism 18 does not operate accordingly.

[0051] The second of the present invention: A feeding method for processing carbendazim suspension concentrate, using the above-mentioned feeding device, comprises the following steps: S1, placing a plurality of filling bottles 29 on the conveying mechanism 18 in sequence, with their bottle openings facing upwards; S2, start the driving component to move the cylinder 2 upward. As the cylinder 2 moves upward, the push rod 4 pulls the piston 3 to move downward in the cylinder 2, causing negative pressure to form in the cylinder 2. At this time, the one-way valve 7 of the feed port 6 automatically opens, allowing the carbendazim suspension liquid to flow into the cylinder 2 from the feed port 6 until the cylinder 2 is filled with the required amount of liquid. At the same time, the transmission component drives the main shaft 19 to rotate to operate the conveying mechanism 18. The conveying mechanism 18 operates to convey the empty filling bottle 29 to the predetermined position. The driving component continues to operate and drives the cylinder 2 to move downward. The push rod 4 pushes the piston 3 to move upward in the cylinder 2. When the discharge port 5 reaches the preset position (aligned with the filling bottle 29 port and the discharge end slightly extends into the filling bottle 29 port), the discharge port 5 opens, and the liquid is conveyed from the cylinder 2 to the filling bottle 29 through the discharge port 5. At the same time, the conveying mechanism 18 remains stationary, and the filling bottle 29 placed on the conveying mechanism 18 also remains stationary, so that the discharge port 5 can accurately extend into the filling bottle 29 port.
