Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment technology, and in particular to a liquid fertilizer feeding device. Background Technology

[0002] As modern agriculture develops towards intelligence and precision, liquid fertilizers are widely used due to their advantages such as balanced nutrients, high absorption efficiency, and convenient application. In the production or filling process of liquid fertilizers, a fixed amount of liquid fertilizer needs to be injected into multiple bottles. Currently, some automated feeding equipment is used in the liquid filling field, but it generally suffers from the following shortcomings: complex structure, difficult maintenance, and feeding accuracy affected by position.

[0003] Utility model patent CN220999212U discloses a bottling mechanism for bottled fertilizer, including a conveying device with a filling barrel placed on a conveyor belt. An arched frame is fixed to the top of the conveying device. The mechanism also includes a material conveying assembly, a storage barrel fixed to the top of the arched frame, with a material conveying pipe connected to the lower end of the storage barrel, and a filling pipe fixedly connected to the lower end of the material conveying pipe; a lifting assembly; a splash-proof assembly; and a scraping assembly. A connecting rod is movably sleeved within an annular plate, with a scraper fixedly connected to one end of the connecting rod and a limiting plate fixedly connected to the other end. This utility model lowers the filling pipe embedded within the pallet by lowering the pallet. The filling pipe enters the filling barrel for filling. During the descent of the filling pipe, the annular plate surrounding the filling pipe descends synchronously, with the lower end of the annular plate abutting against the top of the filling barrel. The enclosed area formed by the annular plate prevents some liquid from splashing out.

[0004] This solution enables the addition of liquid fertilizer to filling barrels conveyed by a conveyor belt. However, in actual use, the lack of a way to limit the position of the filling barrels during conveyor belt transport can easily lead to positional errors, resulting in inaccurate filling or leakage.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , 2 As shown in Embodiment 1, a liquid fertilizer feeding device includes a device body 1, a cantilever support platform 2 on the device body 1, a material tray 3 rotatably mounted on the cantilever support platform 2, and a plurality of bottle slots 4 for accommodating fertilizer bottles on the material tray 3. The material tray 3 is connected to a first driver 5 mounted on the cantilever support platform 2. The device body 1 is provided with a conveying mechanism 6 for conveying the fertilizer bottles, and the conveying mechanism 6 is located below the material tray 3. The device body 1 on both sides of the material tray 3 is provided with a feeding guide mechanism 7 and a discharging guide mechanism 8 corresponding to the bottle slots 4 located on both sides of the material tray 3, respectively. By driving the material tray to rotate intermittently through the first driver, combined with the conveying mechanism, the feeding guide mechanism, and the discharging guide mechanism, automatic feeding, positioning, addition, and discharging of fertilizer bottles are realized, greatly reducing manual intervention. The equipment body 1 is provided with a vertical adjustment mechanism 9. The movable end of the vertical adjustment mechanism 9 is provided with a mounting base 10. The mounting base 10 is provided with a needle tube 11. The lower end of the needle tube 11 corresponds to the movement path of the bottle tank 4. The needle tube 11 is connected to the liquid supply component 12 provided on the equipment body 1. The vertical adjustment mechanism can freely adjust the height of the needle tube. The height of the needle tube can be adjusted according to actual needs, so as to adapt to the needs of various specifications of bottles.

[0019] Specifically, in this embodiment, the material tray is disc-shaped with four bottle slots 4 evenly distributed around its circumference for placing standard-diameter bottles. In actual use, by changing material trays of different sizes and matching bottle slots of different sizes, it is possible to accommodate bottles of different specifications. The bottle slots 4 are U-shaped openings that can accommodate bottles and move with them when rotated, while also facilitating the entry and exit of bottles. A rotating shaft 13 is provided at the axis of the material tray 3, and the rotating shaft 13 is rotatably engaged with the cantilever support platform 2. The upper end of the rotating shaft 13 is connected to the first driver 5 through a belt drive pair 14. The first driver 5 is a servo motor, which is connected to the main control system. In this embodiment, the main control system includes a microcontroller installed on the equipment body, which controls the start, stop, and rotation angle of the servo motor, so that the material tray 3 rotates in steps of 90°, realizing the cyclic operation of four workstations.

[0020] Example 2: A liquid fertilizer feeding device, based on Example 1, such as... Figure 3As shown, the conveying mechanism 6 includes a first conveyor belt mounted on the equipment body 1. The first conveyor belt is driven by an independent motor and linked with the main control system. The first conveyor belt can feed the bottle into the bottle trough 4 on one side via the feeding guide mechanism, and at the same time, it can move the bottle after filling from the bottle trough on the other side and send it out via the discharge guide mechanism, thereby realizing the continuous transfer of the bottle and meeting the actual filling requirements.

[0021] In addition, the main body 1 includes a base frame 15, which provides a support foundation for the entire equipment. A housing 16 is fixedly mounted on the base frame 15. The housing 16 has a central hole for engaging with the material tray 3. A gap is left between the inner wall of the central hole and the outer wall of the material tray to avoid affecting the rotation of the material tray. At the same time, it can also limit the outer side of the bottle to prevent the bottle from falling out of the bottle slot 4. Openings 17 are provided on both sides of the central hole. The feeding guide mechanism 7 and the discharging guide mechanism 8 are respectively set with the openings 17 on both sides, thereby providing channels for the bottles to enter and exit using the openings on both sides.

[0022] Both the feeding guide mechanism 7 and the discharging guide mechanism 8 include a pair of second conveyor belts 18 fixedly mounted on the base frame 11. Each pair of second conveyor belts 18 is symmetrically arranged on both sides above the conveying mechanism 6. In this embodiment, the gap between each pair of second conveyor belts is the same as or slightly larger than the outer diameter of the bottle, thereby enabling fine-tuning of the conveying position of the bottle entering from both sides, allowing it to smoothly enter and exit the bottle slot 4.

[0023] As a further specific implementation, in order to obtain the conveying position of the bottle, a sensor unit 19 for identifying the position of the bottle is provided on the device body 1 in this embodiment. In this embodiment, the sensor unit 19 is a photoelectric sensor, and a total of five are provided. Three of the photoelectric sensors are respectively matched with the bottle slots corresponding to the two opening positions and the material slots corresponding to the needle tubes to identify whether there is a bottle in the material slot. The other two photoelectric sensors are respectively matched with the inlet end of the feeding guide mechanism 7 and the outlet end of the discharging guide mechanism 8 to identify the entry and exit status of the bottle.

[0024] After the photoelectric sensor detects that the bottle has entered the feeding guide mechanism 7, the control system controls the first driver to rotate the material tray 3 one station, so that the empty bottle slot 4 is aligned with the opening of the feeding guide mechanism 7 in the feeding direction. The conveying mechanism 6 transports the bottle into the bottle slot 4. During this process, the feeding guide mechanism 7 works synchronously to prevent the bottle conveying position from deviating and to maintain stable and accurate conveying.

[0025] Example 3: A liquid fertilizer feeding device, based on Example 2, such as... Figure 4As shown, the vertical adjustment mechanism 9 includes a column 20 fixedly mounted on the base frame 15, a mounting base 10 slidably mounted on the column 20, a support 21 at the top of the column 20, an adjustable screw 22 that can rotate between the support 21 and the base frame 15, a screw nut that cooperates with the adjustable screw on the mounting base, and the adjustable screw 22 is connected to the second driver 27 fixedly mounted on the support 21.

[0026] When adjusting the height of the syringe, the second driver operates, driving the adjusting screw to rotate. In turn, the adjusting screw and the screw nut work together to move the mounting base along the column axis.

[0027] Furthermore, a clamping block 23 is provided on the mounting base 10. The clamping block 23 has a through hole for inserting the needle tube 11, and a handle for engaging with the side wall of the needle tube 11. By rotating the handle, the inner end of the handle can pass through the clamping block and press against the side wall of the needle tube, thereby fixing the needle tube.

[0028] In addition, the liquid supply assembly 12 includes a delivery pipe 24 connected to the needle tube 11. The delivery pipe 24 is equipped with a solenoid valve, which is used to control the on / off of liquid fertilizer delivery to prevent leakage. The delivery pipe 24 is connected to a fluid pump 25, and the fluid pump 25 is connected to a hopper 26.

[0029] During operation, the bottle is conveyed by the conveying mechanism 6. When it enters the feeding guide mechanism 7, the first photoelectric sensor detects that the bottle is in position, and the first driver 5 drives the material tray 3 to rotate, aligning the empty bottle slot 4 with the bottle. The conveying mechanism 6, in conjunction with the feeding guide mechanism, sends the bottle into the bottle slot 4. The material tray 3 continues to rotate to the feeding position corresponding to the bottom of the syringe. The liquid supply component 12 injects a measured amount of liquid fertilizer into the bottle through the syringe tube 11. During this process, the vertical height of the lower end of the syringe tube is controlled by the vertical movement mechanism to prevent liquid splashing. After feeding is completed, the material tray 3 rotates to the discharge position, and the conveying mechanism 6 sends the bottle out of the bottle slot 4 through the discharge guide mechanism 8, completing one work cycle.

[0030] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
