When different materials need to be changed for quantitative packaging, the materials adsorbed on the inner wall of the feeding hopper need to be manually cleaned first, which takes a long time and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an internal cleaning device for a quantitative packaging scale used in fertilizer production, which improves production efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a machine body, a feeding hopper disposed on the machine body, and a cleaning frame connected to the bottom of the feeding hopper. A quantitative weighing device is connected to the bottom of the cleaning frame. A baffle plate that can be controlled to open and close by the quantitative weighing device is horizontally disposed at the bottom end of the cleaning frame. A first cleaning hole with a rectangular longitudinal section is opened on one side of the cleaning frame and communicates with the baffle plate. A side door that can be opened and closed is rotatably disposed on the side of the cleaning frame near the first cleaning hole. A striking device for striking the feeding hopper is symmetrically disposed on the outer side of the cleaning frame.

[0006] A further feature of this invention is that the striking element includes a bracket disposed on the outside of the cleaning frame and a rotating wheel rotatably disposed on the bracket in a vertical direction. A reduction motor for driving the rotating wheel is disposed on the bracket. A first connecting rod is disposed on one side of the rotating wheel in a horizontal direction. A positioning cylinder is horizontally disposed on the bracket. A striking rod is movably disposed on the inner wall of the positioning cylinder. A second connecting rod is rotatably disposed on the first connecting rod. The second connecting rod is rotatably connected to the end of the striking rod away from the feeding hopper. When the rotating wheel rotates, the second connecting rod can push the striking rod to abut against the outer wall of the feeding hopper.

[0007] A further feature of this invention is that a striking block is provided on the side of the striking rod near the hopper, and the striking block can be movably fitted against the outer wall of the hopper.

[0008] A further feature of this invention is that a second cleaning hole of the same size as the first cleaning hole is provided on the side of the cleaning frame away from the side door, a pusher plate is movably disposed in the second cleaning hole, the bottom end of the pusher plate is movably attached to the baffle plate, and a pusher component for pushing the pusher plate is provided on the machine body.

[0009] A further feature of this invention is that the pushing component includes a drive cylinder horizontally disposed on the machine body and a pushing rod disposed at the output end of the drive cylinder. The end of the pushing rod is fixedly connected to the pushing plate, and the pushing rod can push the pushing plate to move to fit against the inner wall of the first cleaning hole.

[0010] A further feature of this invention is that a material carrier plate is horizontally arranged on the machine body, and a collection frame is movably arranged on the material carrier plate, wherein the top of the collection frame is at a horizontal plane not higher than the bottom of the first cleaning hole.

[0011] A further feature of this invention is that limiting plates are symmetrically arranged on both sides of the material carrier plate, and the two sides of the collection frame can be movably attached to the two limiting plates respectively.

[0012] A further feature of this invention is that a magnetic handle is provided on the side of the side door away from the baffle plate.

[0013] A further feature of this invention is that a magnetic positioning block is provided on the feeding hopper, and the magnetic handle can be magnetically connected to the magnetic positioning block.

[0014] A further feature of this invention is that the striking block is made of a high-density material.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a first cleaning hole, a side door, and a knocking device, when the hopper needs to be cleaned to change to different materials, the baffle plate is in a closed state. Therefore, the cleaning frame and the quantitative weighing device are not connected. At this time, the knocking device is opened to knock on the outer wall of the hopper, causing the material adsorbed in the hopper to fall onto the baffle plate at the bottom of the cleaning frame under the vibration of the hopper. Then, the side door is opened, and the material on the baffle plate can be cleaned manually. By setting up a side door and a knocking device, the material falls from the inner wall of the hopper under the knocking action of the knocking device. The worker only needs to open the side door to clean the material on the baffle plate, thereby reducing the time required for workers to clean the hopper and improving production efficiency.

[0017] 2. By setting up a rotating wheel, a first connecting rod, and a striking rod, the rotating wheel drives the first connecting rod to rotate (it should be noted that there is a certain distance between the first connecting rod and the central axis of the rotating wheel), which in turn drives the second connecting rod to move. This causes the striking rod to move closer to or further away from the feeding hopper along the positioning cylinder. When the striking rod touches the feeding hopper, it strikes the feeding hopper, causing it to vibrate. Therefore, by setting up the striking rod and rotating wheel, the striking rod strikes the feeding hopper during its reciprocating movement, eliminating the need for workers to manually clean the material on the inner wall of the feeding hopper, thus improving production efficiency.

[0018] 3. By setting up a pusher plate, drive motor, etc., after the material on the inner wall of the hopper falls to the baffle plate, the side door is opened, and then the drive cylinder is opened to drive the pusher plate to move from the second cleaning hole to the first cleaning hole. During this process, the pusher plate pushes the material on the baffle plate out through the first cleaning hole, eliminating the need for workers to manually clean the material on the baffle plate, thereby further shortening the cleaning time and improving production efficiency.

Detailed Implementation

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] This utility model provides a cleaning device for the hopper of a quantitative packaging scale used in fertilizer production, such as... Figures 1 to 4 As shown, the device includes a body 1, a feeding hopper 2 mounted on the body 1, and a cleaning frame 3 connected to the bottom of the feeding hopper 2. A quantitative weighing device 4 is connected to the bottom of the cleaning frame 3. A baffle plate 5, which can be controlled to open and close by the quantitative weighing device 4, is horizontally mounted at the bottom of the cleaning frame 3. A first cleaning hole 6 with a rectangular longitudinal section is opened on one side of the cleaning frame 3 and communicates with the baffle plate 5. A side door 7, which can be opened and closed, is rotatably mounted on the side of the cleaning frame 3 near the first cleaning hole 6. A striking device 8 for striking the feeding hopper 2 is symmetrically mounted on the outer side of the cleaning frame 3.

[0027] Furthermore, the striking element 8 includes a bracket 8a disposed on the outside of the cleaning frame 3 and a rotating wheel 8b rotatably disposed on the bracket 8a in the vertical direction. A reduction motor 9 for driving the rotating wheel 8b is disposed on the bracket 8a. A first connecting rod 10 is disposed on one side of the rotating wheel 8b in the horizontal direction. A positioning cylinder 11 is horizontally disposed on the bracket 8a. A striking rod 12 is movably disposed on the inner wall of the positioning cylinder 11. A second connecting rod 13 is rotatably disposed on the first connecting rod 10. The second connecting rod 13 is rotatably connected to the end of the striking rod 12 away from the feeding hopper 2. When the rotating wheel 8b rotates, the second connecting rod 13 can push the striking rod 12 to abut against the outer wall of the feeding hopper 2.

[0028] Furthermore, a striking block 14 is provided on the side of the striking rod 12 near the feeding hopper 2, and the striking block 14 can be movably attached to the outer wall of the feeding hopper 2.

[0029] Furthermore, a second cleaning hole 15 with the same size as the first cleaning hole 6 is provided on the side of the cleaning frame 3 away from the side door 7. A pusher plate 16 is movably disposed in the second cleaning hole 15. The bottom end of the pusher plate 16 can be movably attached to the baffle plate 5. A pusher component 17 for pushing the pusher plate 16 is provided on the machine body 1.

[0030] Furthermore, the pusher 17 includes a drive cylinder 17a horizontally disposed on the machine body 1 and a pusher rod 17b disposed at the output end of the drive cylinder 17a. The end of the pusher rod 17b is fixedly connected to the pusher plate 16, and the pusher rod 17b can push the pusher plate 16 to move to fit against the inner wall of the first cleaning hole 6.

[0031] Furthermore, a material carrier plate 18 is horizontally arranged on the body 1, and a collection frame 19 is movably arranged on the material carrier plate 18. The top of the collection frame 19 is not higher than the bottom of the first cleaning hole 6.

[0032] Furthermore, limiting plates 20 are symmetrically arranged on both sides of the material carrier plate 18, and the two sides of the collection frame 19 can be movably attached to the two limiting plates 20 respectively.

[0033] Furthermore, a magnetic handle 21 is provided on the side of the side door 7 away from the baffle plate 5.

[0034] Furthermore, a magnetic positioning block 22 is provided on the feeding hopper 2, and the magnetic handle 21 can be magnetically connected to the magnetic positioning block 22.

[0035] Furthermore, the striking block 14 is made of a high-density material.

[0036] When cleaning the hopper 2 is required to change to different materials, the baffle plate 5 is in a closed state, so the cleaning frame 3 and the quantitative weighing piece 4 are not connected. At this time, the reduction motor 9 is turned on first, driving the rotating wheel 8b to rotate. When the rotating wheel 8b rotates, it drives the first connecting rod 10 to rotate (it should be noted that there is a certain distance between the central axis of the first connecting rod 10 and the rotating wheel 8b), which in turn drives the second connecting rod 13 to move, so that the striking rod 12 moves closer to or further away from the hopper 2 along the positioning cylinder 11. When the striking block 14 touches the hopper 2, it strikes the hopper 2, causing the hopper 2 to vibrate and strike the outer wall of the hopper 2. Under the vibration of the hopper 2, the material adsorbed on the hopper 2 falls onto the baffle plate 5 at the bottom of the cleaning frame 3. Then the side door 7 is opened, allowing the material to pass through. The magnetic handle 21 is attracted to the magnetic positioning block 22. Then, the drive cylinder 17a is opened, driving the pusher plate 16 to move from the second cleaning hole 15 to the first cleaning hole 6. During this process, the pusher plate 16 pushes the material on the baffle plate 5 from the first cleaning hole 6 into the collection frame 19 (the quantitative weighing component 4, which includes the solenoid valve, weight sensing device, etc., is prior art and will not be described in detail without affecting the understanding of the actual scope of the technology protected by this patent by those skilled in the art). By setting the side door 7, the knocking component 8, etc., the material falls from the inner wall of the feed hopper 2 under the knocking action of the knocking component 8. The worker only needs to open the side door 7 to clean the material on the baffle plate 5, thereby reducing the time required for the worker to clean the feed hopper 2 and achieving the purpose of improving production efficiency.

[0037] By setting up a striking rod 12, a rotating wheel 8b, etc., the material hopper 2 is struck during the reciprocating movement of the striking rod 12, eliminating the need for workers to manually clean the material on the inner wall of the material hopper 2, thereby improving production efficiency.

[0038] By setting up a pusher plate 16, a drive motor, etc., after the material on the inner wall of the hopper 2 falls to the baffle plate 5, the side door 7 is opened, and then the drive cylinder 17a is opened to drive the pusher plate 16 to move from the second cleaning hole 15 to the first cleaning hole 6. During this process, the pusher plate 16 pushes the material on the baffle plate 5 out of the first cleaning hole 6, eliminating the need for workers to manually clean the material on the baffle plate 5, thereby further shortening the cleaning time and improving production efficiency.

[0039] By setting the striking block 14, the contact area with the feeding hopper 2 is increased, thereby increasing the striking effect of the striking block 14 on the feeding hopper 2, so that the material adsorbed on the feeding hopper 2 can fall down quickly.

[0040] By setting up a collection box 19, the material falling from the first cleaning hole 6 is collected, preventing the material from scattering everywhere.

[0041] By setting up a magnetic handle 21 and a magnetic positioning block 22, the side door 7 is fixed to prevent it from rotating during the material cleaning process of the pusher plate 16, which would affect the cleaning effect.

[0042] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0043] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
