By setting up the mixing and conveying mechanism, the compound fertilizer raw material is transported from the feed pipe to the loading bin. The mixing shaft and mixing blades of the compound fertilizer raw material work together to break up the raw material, which is then fed onto a conveyor belt for transport. A dust collector removes dust from the raw material. When the fertilizer to be weighed is conveyed to the loading bin above the weighing sensor, the weighing sensor can sense whether the weight of the fertilizer reaches the standard value. If the weight does not meet the standard, the feed pipe can be refilled, and the first motor can be started to drive the mixing shaft to convey material, thus replenishing the fertilizer to be weighed.

[0004] However, the following problems were found in the implementation of the relevant technology: When in use, the device can only transport fertilizer into the barrel. In reality, most fertilizers are packaged in woven bags, and the device also needs to pour the fertilizer from the barrel into the woven bag.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] Implementation

[0029] Please see Figure 1 -5. A fertilizer granule weighing and packaging machine, comprising: a storage box 1, a support 3, a conveying pipe 2, a spreading component 5 and a weighing component 14, wherein the storage box 1 is fixedly installed on the top of the support 3 and the input end of the conveying pipe 2 is fixedly connected to the storage box 1.

[0030] A support rod 4 is provided at the top of the bracket 3, a gathering barrel 6 is provided at the end of the support rod 4, a lifting rod 10 is provided on the outer wall of the gathering barrel 6, and a spreading component 5 is provided at the end of the lifting rod 10.

[0031] The weighing component 14 is positioned directly below the spreading component 5.

[0032] The technical solution provided in this embodiment is as follows: In use, first, sufficient fertilizer is placed inside the storage box 1. Then, the packaging bag is placed above the support plate 143. Next, the inner side of the bag is fitted over the outer wall of the fixing rod 506. Then, a moving rod 502 is pushed in, causing the pull plate 504 to be located on the inner wall of the bag. Then, the moving rod 502 is pushed forward, and under the action of the spring 503, it moves outward, causing the pull plate 504 to tighten the bag opening. Then, another moving rod 502 is pushed in, causing the pull plate 504 of the other moving rod 502 to tighten the bag opening, thus opening the bag. After opening the bag, the pull rope 13 is wound around the winding block. 12. To prevent the bags from tipping over due to increased weight during bagging, the next step is to start the drive motor 7. The rotation of the drive motor 7 causes the screw rod 8 to rotate, which transports the fertilizer inside the storage box 1 to the output port 9. The fertilizer falls from the output port 9 into the collecting bucket 6 and then into the bag. At the same time, the weight sensor 142 measures the weight of the fertilizer in real time. When the weight of the fertilizer reaches the predetermined value, the drive motor 7 stops rotating, cutting off the fertilizer delivery. Then, the two moving rods 502 are pushed inward to remove the bag opening. The next step is to untie the pull rope 13 and proceed with the next step of processing the bagged fertilizer.

[0033] Furthermore, the weighing assembly 14 includes a base plate 141, a weight sensor 142, a support plate 143, and a lifting leg 144. The weight sensor 142 is disposed on the upper surface of the base plate 141, the support plate 143 is disposed on the upper surface of the weight sensor 142, and the lifting leg 144 is disposed on the lower wall of the base plate 141.

[0034] Specifically, the weighing component 14 can effectively and accurately bear weight when there is tilting or center of gravity shift during bagging by setting multiple weight sensors 142. Furthermore, the angle and height of the base plate 141 can be adjusted by rotating and adjusting the height of the lifting support leg 144.

[0035] Furthermore, the spreading assembly 5 includes a fixed ring 501, a movable rod 502, and a pull plate 504. The movable rod 502 is inserted into the inner wall of the fixed ring 501, and a spring 503 is sleeved on the outer wall of the movable rod 502. One end of the spring 503 is fixedly connected to the outer wall of the fixed ring 501, and the other end of the spring 503 is fixedly connected to the outer wall of the movable rod 502. A pull plate 504 is provided at the end of the movable rod 502, and a pin 505 is provided on the outer wall of the pull plate 504.

[0036] Specifically, by setting up the movable rod 502 and the spring 503, the movable rod 502 can always have an outward force. When the pull plate 504 is located inside the bag opening, the force of the spring 503 can open the bag opening.

[0037] Furthermore, a fixing rod 506 is fixedly connected to the inner wall of the fixing ring 501, and a fixing ball 507 is provided at the end of the fixing rod 506.

[0038] Specifically, the design of the fixing ball 507 prevents the fixing rod 506 from tearing the bag when it is removed because the fixing rod 506 cannot move.

[0039] Furthermore, the output end of the gathering bucket 6 is located at the center of the spreading component 5.

[0040] Specifically, the setting at the center of the spreading component 5 can prevent fertilizer from spilling due to positional deviation when waste is transported through the gathering bucket 6.

[0041] Furthermore, both the movable rod 502 and the fixed rod 506 are arranged in a circular array.

[0042] Specifically, the circular array design allows the bag to open more fully, preventing incomplete opening of the bag due to incorrect movement path of the rod.

[0043] Furthermore, a spiral rod 8 is sleeved inside the conveying pipe 2, and a drive motor 7 is fixedly installed on the outer wall of the conveying pipe 2. The output end of the drive motor 7 is fixedly connected to one side of the spiral rod 8.

[0044] Specifically, by driving the screw rod 8 through the drive motor 7, the amount of fertilizer output from the delivery pipe 2 can be controlled simply by controlling the start of the drive motor 7, making the amount of fertilizer output more controllable and precise.

[0045] Furthermore, the outer wall of the conveying pipe 2 is provided with an output port 9, which is located directly above the gathering barrel 6.

[0046] Furthermore, a support frame 11 is provided above the weighing component 14, and a winding block 12 is provided on the outer wall of the support frame 11, with a pull rope 13 wound around the outer wall of the winding block 12.

[0047] Specifically, the support frame 11 and the pull rope 13 are designed to prevent the bag from tipping over during bagging, which could cause spillage or injury to personnel.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
