Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a quantitative feeding mechanism and a water-soluble fertilizer production device. Background Art

[0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely soluble in water. It can dissolve quickly in water and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve water-fertilizer integration and save water, fertilizer and labor.

[0003] Water-soluble fertilizers need to be quantitatively fed during the production process (such as the packaging process). In order to ensure the accuracy of the quantitative feeding, most of the quantitative feeding mechanisms in the prior art first discharge the materials from the storage bin into the intermediate container for weighing, and then pour the weighed materials into the packaging bag. In this process, two waiting times are required (one for feeding the materials into the intermediate container and one for discharging the materials from the intermediate container). The working efficiency is low and cannot meet the requirements of large-scale production. Therefore, based on the above technical problems, they need to be solved. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the utility model provides a quantitative feeding mechanism and a water-soluble fertilizer production device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a quantitative feeding mechanism, comprising a frame, a storage bin fixed on the frame, the bottom of the storage bin is provided with a discharge port, and also includes an upper turntable and a lower turntable, the upper turntable is rotatably connected to the frame by a rotating shaft and is connected to an intermittent rotating mechanism, the rotating shaft is provided with a key slot extending along its axial direction, and two upper measuring cylinders are symmetrically arranged on the upper turntable, both ends of the upper measuring cylinder are opened, one of the upper measuring cylinders is arranged corresponding to the discharge port of the storage bin, and a receiving hopper is arranged below the other upper measuring cylinder, the lower turntable is fixed on the connecting sleeve, the connecting sleeve is sleeved on the outside of the rotating shaft, the connecting sleeve is provided with a connecting key matching the key slot, the connecting sleeve is connected to a lifting assembly, the lower turntable is provided with a lower measuring cylinder corresponding to the upper measuring cylinder, the lower measuring cylinder is sleeved on the outside of the upper measuring cylinder and slides with the upper measuring cylinder along the axial direction, a discharge valve plate is provided at the bottom of the lower measuring cylinder, and a discharge mechanism for automatically discharging the discharge valve plate is provided on the lower turntable.

[0006] The upper measuring cylinder and its corresponding lower measuring cylinder constitute an intermediate container for quantifying materials. The materials in the storage bin enter the intermediate container below it for quantification under the action of gravity. When the intermediate container is full, the materials no longer enter, and then the intermittent rotation mechanism drives the upper turntable and the lower turntable to rotate 180° synchronously, so that the intermediate container filled with materials rotates to the top of the receiving hopper, and the discharge valve plate of the intermediate container opens, and the materials in it enter the receiving hopper. At the same time, another intermediate container is located just below the storage bin for feeding. Therefore, the feeding of one intermediate container and the discharging of another intermediate container are carried out simultaneously, which greatly reduces the waiting time and improves work efficiency.

[0007] Preferably, a crossbeam for supporting the upper turntable is provided on the frame, and the upper turntable is rotatably matched with the crossbeam via a bearing.

[0008] The crossbeam is provided with a through hole for installing the upper turntable to ensure the balance and stability of the upper turntable.

[0009] Preferably, the intermittent rotation mechanism includes a driven gear and a driving wheel, the driven gear is connected to the rotating shaft, the driving wheel is rotatably connected to the frame and connected to a rotating motor, and meshing teeth arranged in an arc shape and meshing with the driven gear are provided on the circumference of the driving wheel.

[0010] The rotating motor drives the driving wheel to rotate. When its meshing teeth rotate to a position meshing with the driven gear, the driven gear rotates, thereby causing the upper turntable and the lower turntable to rotate. When the meshing teeth rotate to a position away from the driven gear, the driven gear no longer rotates, and the upper turntable and the lower turntable stop.

[0011] Preferably, two outer stop edges are sequentially provided on the connecting sleeve in the vertical direction, and the lifting assembly includes a threaded rod, a guide rod, and a lifting ring. The threaded rod is rotatably connected to the frame and is connected to a lifting motor. The guide rod is fixedly connected to the frame. The lifting ring is sleeved on the outside of the connecting sleeve and is located between the two outer stop edges. The lifting ring is connected to a connecting arm, and the connecting arm is provided with an internal threaded hole that threadably cooperates with the threaded rod and a guide hole that slides with the guide rod.

[0012] The lifting motor drives the threaded rod to rotate forward and reversely, thereby realizing the lifting and lowering of the lifting ring. The lifting ring acts on the connecting sleeve through two outer stops, so that the connecting sleeve is lifted and lowered synchronously, thereby realizing the lifting and lowering of the lower turntable; when the lower turntable rotates, the connecting sleeve rotates in the lifting ring without causing motion interference.

[0013] Preferably, the discharge valve plate is rotatably connected to the lower measuring cylinder via a pin shaft, and the discharge mechanism includes a discharge ring sleeved on the outside of the connecting sleeve, and the discharge ring is connected to the connecting arm via a connecting rod, and the upper surface of the end of the discharge valve plate away from the lower measuring cylinder abuts against the lower surface of the discharge ring, and the end of the discharge ring close to the receiving hopper is the discharge end, the thickness of the discharge end is smaller than that of other positions, and a transition slope is provided between the discharge end and its adjacent position.

[0014] When the intermediate container is located below the storage bin or rotates toward the receiving hopper, the upper surface of its discharge valve plate abuts against the lower surface of the discharge sleeve. Therefore, even if the intermediate container is full of materials, the discharge valve plate will not rotate and will always remain in a horizontal closed state due to the blocking effect of the discharge sleeve to prevent material leakage. When the intermediate container is located above the receiving hopper, the upper surface of the discharge valve plate gradually enters the discharge end through the transition slope. At this time, under the action of the gravity of the material, the discharge valve plate rotates around the pin shaft to open, and the material enters the receiving hopper. After the discharge is completed, as the intermediate container rotates, the discharge valve plate is closed again under the action of the lower surface of the discharge sleeve.

[0015] A water-soluble fertilizer production device comprises any one of the quantitative feeding mechanisms described above.

[0016] The utility model also includes other components that enable a quantitative feeding mechanism and a water-soluble fertilizer production device to be used normally, which are all conventional technical means in the art. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the art.

[0017] The utility model provides two adjustable intermediate containers, and enables the feeding of one intermediate container and the discharging of the other intermediate container to be carried out simultaneously, thereby greatly reducing the waiting time and improving the working efficiency.

[0025] Example

[0026] See also Figure 1-3A water-soluble fertilizer production device includes a quantitative feeding mechanism, which includes a frame, a storage bin 1 fixed on the frame, a discharge port at the bottom of the storage bin, an upper turntable 2, and a lower turntable 3. The upper turntable 2 is rotatably connected to the frame through a rotating shaft 4 and is connected to an intermittent rotating mechanism. The rotating shaft 4 is provided with a keyway extending along its axial direction. Two upper measuring cylinders 5 are symmetrically provided on the upper turntable 2, and both ends of the upper measuring cylinders 5 are opened. One of the upper measuring cylinders 5 is provided corresponding to the discharge port of the storage bin. A receiving hopper 6 is provided under the other upper measuring cylinder, the lower turntable 3 is fixed on the connecting sleeve 7, the connecting sleeve 7 is sleeved on the outside of the rotating shaft, a connecting key 8 matching the keyway is provided on the connecting sleeve 7, the connecting sleeve 7 is connected with a lifting assembly, a lower measuring cylinder 9 is provided on the lower turntable 3 corresponding to the upper measuring cylinder 5, the lower measuring cylinder 9 is sleeved on the outside of the upper measuring cylinder 5 and slidably cooperates with the upper measuring cylinder 5 along the axial direction, a discharge valve plate 10 is provided at the bottom of the lower measuring cylinder 9, and a discharge mechanism for automatic discharge of the discharge valve plate 10 is provided on the lower turntable 3.

[0027] In this embodiment, the upper measuring cylinder 5 and its corresponding lower measuring cylinder 9 form an intermediate container for quantifying materials. The materials in the storage bin enter the intermediate container below it for quantification under the action of gravity. When the intermediate container is full, the materials no longer enter, and then the intermittent rotation mechanism drives the upper turntable 2 and the lower turntable 3 to rotate 180° synchronously, so that the intermediate container filled with materials rotates to the top of the receiving hopper, and the discharge valve plate 10 of the intermediate container opens, and the materials therein enter the receiving hopper 6. At the same time, another intermediate container is located just below the storage bin for feeding. Therefore, the feeding of one intermediate container and the discharging of another intermediate container are carried out simultaneously, which greatly reduces the waiting time and improves work efficiency.

[0028] A discharge pipe is provided at the bottom of the receiving hopper 6, and a packaging machine can be provided correspondingly below the discharge pipe. The material after being quantitatively measured by the upper measuring cylinder 5 and the lower measuring cylinder 9 first enters the receiving hopper 6, and then enters the packaging bag on the packaging machine for packaging.

[0029] The intermittent mechanism is used to realize the intermittent rotation of the upper turntable 2 and the lower turntable 3. The upper turntable 2 and the lower turntable 3 rotate to realize the position switching of the two intermediate containers. When they are stationary, the intermediate containers are fed or discharged.

[0030] When the upper turntable 2 rotates, the connecting sleeve 7 and the lower turntable 3 are driven to rotate synchronously through the connecting key 8.

[0031] The lifting mechanism drives the connecting sleeve 7 to rise and fall, and the lower turntable 2 rises and falls synchronously with the connecting sleeve 7, thereby changing the depth of the upper measuring cylinder 5 inserted into the lower measuring cylinder 9, and the capacity of the intermediate container can be adjusted to meet different production needs.

[0032] In actual use, a weighing sensor may be provided at the bottom of the discharge valve plate 10 , and each time the capacity of the upper measuring cylinder 5 and the lower measuring cylinder 9 is adjusted, the weighing sensor is used to determine whether the quantitative determination is accurate.

[0033] The frame is provided with a crossbeam 11 for supporting the upper turntable 2, and the upper turntable 2 is rotatably matched with the crossbeam via a bearing.

[0034] In this embodiment, a through hole for mounting the upper turntable 2 is provided on the crossbeam to ensure the balance and stability of the upper turntable 2 .

[0035] The intermittent rotation mechanism includes a driven gear 12 and a driving wheel 13. The driven gear 12 is connected to the rotating shaft 4. The driving wheel 13 is rotatably connected to the frame and is connected to a rotating motor. The driving wheel is provided with meshing teeth arranged in an arc shape on the circumference of the driven gear 12.

[0036] The rotating motor drives the driving wheel 13 to rotate. When its meshing teeth rotate to a position meshing with the driven gear 12, the driven gear 12 rotates, thereby causing the upper turntable 2 and the lower turntable 3 to rotate. When the meshing teeth rotate to a position away from the driven gear 12, the driven gear 12 no longer rotates, and the upper turntable 2 and the lower turntable 3 stop moving.

[0037] Two outer stop edges 14 are sequentially provided on the connecting sleeve 7 in the vertical direction. The lifting assembly includes a threaded rod 15, a guide rod 16, and a lifting ring 17. The threaded rod is rotatably connected to the frame and is connected to a lifting motor. The guide rod 16 is fixedly connected to the frame. The lifting ring 17 is sleeved on the outer side of the connecting sleeve 7 and is located between the two outer stop edges 14. The lifting ring 17 is connected to a connecting arm 18. The connecting arm 18 is provided with an internal threaded hole that is threadedly matched with the threaded rod and a guide hole that is slidably matched with the guide rod 16.

[0038] The lifting motor drives the threaded rod to rotate forward and reversely, thereby realizing the lifting and lowering of the lifting ring. The lifting ring acts on the connecting sleeve 7 through two outer stop edges 14, so that the connecting sleeve is lifted and lowered synchronously, thereby realizing the lifting and lowering of the lower turntable 3; when the lower turntable 3 rotates, the connecting sleeve 7 rotates in the lifting ring 17 without causing motion interference.

[0039] The guide rod 16 is provided to provide guidance for the lifting and lowering of the lifting ring 17 .

[0040] The discharge valve plate 10 is rotatably connected to the lower measuring cylinder 9 through a pin shaft, and the discharge mechanism includes a discharge ring 19 sleeved on the outside of the connecting sleeve 7, and the discharge ring 19 is connected to the connecting arm 18 through a connecting rod. The upper surface of the end of the discharge valve plate 10 away from the lower measuring cylinder 9 abuts against the lower surface of the discharge ring 19, and the end of the discharge ring close to the receiving hopper is the discharge end 20, the thickness of the discharge end is smaller than that of other positions, and a transition slope is provided between the discharge end and its adjacent position.

[0041] When the intermediate container is located below the storage bin or rotates toward the receiving hopper, the upper surface of its discharge valve plate abuts against the lower surface of the discharge sleeve 19. Therefore, even if the intermediate container is full of materials, the discharge valve plate 10 will not rotate and will always remain in a horizontal closed state under the blocking effect of the discharge sleeve 19 to prevent material leakage; when the intermediate container is located above the receiving hopper 6, the upper surface of the discharge valve plate 10 gradually enters the discharge end through the transition slope. At this time, under the action of the gravity of the material, the discharge valve plate 10 rotates around the pin shaft to open, and the material enters the receiving hopper 6. After the discharge is completed, with the rotation of the intermediate container, the discharge valve plate 10 is closed again under the action of the lower surface of the discharge sleeve.

[0042] It should be noted that when the lower turntable 3 is raised or lowered, the discharge collar 19 is raised or lowered therewith; when the lower turntable 3 is rotated, the discharge collar 19 is fixed on the connecting arm 18 and does not rotate, thus ensuring the normal discharge of the material.

[0043] In actual use, the discharge valve plate 10 may also be an automatic discharge valve plate of the prior art, but this embodiment uses a mechanical structure to achieve automatic discharge, which not only simplifies the structure and equipment, reduces equipment costs, but also has higher reliability in use.

[0044] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
