In the existing technology, the connection between double-arm lifting mixers and hoppers mostly adopts a snap-fit ​​structure. The design idea is to manually push the hopper into the rotating body of the equipment, and then use the lifting mechanism of the double arms to lift the hopper into place. Finally, the snap-fit ​​structure is used to realize the automatic clamping of the hopper and the robotic arm, thereby completing the installation and fixation of the hopper to achieve the purpose of rapid replacement.

[0003] However, the existing hopper connection method based on snap-fit ​​structure has obvious defects in practical applications: on the one hand, during the lifting process, due to the lack of a precise guiding and positioning mechanism, the docking position of the snap-fit ​​structure is prone to deviation, making it difficult for the snap-fit ​​between the hopper and the robotic arm to be accurately aligned; on the other hand, from the start of lifting the hopper to the completion of the snap-fit ​​structure clamping, the equipment is not equipped with an effective limiting device, and the hopper may shake or shift due to external force disturbance or mechanical error during the lifting process, and there is even a risk of the hopper falling off.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0026] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a double-arm lifting mixer with easy-to-change hoppers, comprising: The main structure 1 includes a rotating body 11, with a hopper body 12 housed within the inner cavity of the rotating body 11. Mechanical arms 13 are fixedly connected to both sides of the rotating body 11. A housing 14 is located on the side of the mechanical arm 13 furthest from the rotating body 11. A first motor is housed within the housing 14 and cooperates with the mechanical arm 13. A lifting member 15 is located at the top of the rotating body 11. The docking assembly 2 includes docking blocks 21 fixedly connected to the top of both sides of the hopper body 12, docking plates 22 fixedly connected to both sides of the inner cavity of the rotating body 11 and cooperating with the docking blocks 21, rollers 23 fixedly connected to the side of the docking blocks 21 away from the hopper body 12, card seats 24 fixedly connected to all four sides of the top of the hopper body 12, and card blocks 25 fixedly connected to the top of the inner cavity of the rotating body 11 and cooperating with the card seats 24. The limiting component 3 includes a limiting rod 31 fixedly connected to the surface of the hopper body 12, and a fixing member 32 is provided on the surface of the limiting rod 31.

[0027] In the main structure 1, the rotating body 11 provides a space for the hopper body 12, and the robotic arms 13 on both sides can perform corresponding actions under the drive of the first motor. The lifting component 15 is responsible for lifting the hopper body 12. The docking component 2 provides precise guidance for the installation of the hopper body 12 through the cooperation of the docking block 21 and the docking plate 22. The card seat 24 and the card block 25 further ensure the accuracy of docking, effectively solving the problem of easy deviation of the docking position in the existing snap-fit ​​structure. In the limiting component 3, the limiting rod 31 cooperates with the fixing component 32 to effectively limit the hopper body 12 during the lifting process, preventing it from shaking, shifting or even falling off, thus ensuring the safety and stability of the equipment operation.

[0028] It should be noted that the rotating body 11, the hopper body 12, the robotic arm 13, and the first motor are all existing technologies, which are clearly known to those skilled in the art, and will not be described in detail. Example 2

[0029] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the lifting component 15 includes a second motor 15-1 fixedly connected to both sides of the top of the rotating body 11. The output shaft of the second motor 15-1 is fixedly connected to a lead screw 15-2. The bottom of the lead screw 15-2 passes through the rotating body 11, and a threaded sleeve 15-3 is threadedly connected to the inner cavity of the rotating body 11. The bottom of the threaded sleeve 15-3 passes through the rotating body 11 and is fixedly connected to a lifting plate 15-4.

[0031] The second motor 15-1 serves as the power source, and its output shaft drives the lead screw 15-2 to rotate. The lead screw 15-2 is threadedly connected to the threaded sleeve 15-3, thereby converting the rotational motion into linear motion, realizing the up-and-down movement of the lifting plate 15-4, providing power support for the lifting of the hopper body 12, and ensuring the stability and controllability of the lifting process.

[0032] Specifically, lifting blocks 15-5 are fixedly connected to the bottom of both sides of the hopper body 12, and lifting grooves 15-6 are opened on the surface of the lifting plate 15-4, which cooperate with the lifting blocks 15-5.

[0033] By setting lifting blocks 15-5 at the bottom of both sides of the hopper body 12 and opening lifting grooves 15-6 on the surface of the lifting plate 15-4 to match them, the lifting plate 15-4 can accurately drive the hopper body 12 to rise synchronously during the lifting process, which further improves the stability and accuracy of the hopper lifting process and avoids misalignment of the hopper during the lifting process.

[0034] Specifically, a slide rod 15-7 is fixedly connected to the top of the lifting plate 15-4, and a slide groove 15-8 is provided at the bottom of the rotating body 11, which cooperates with the slide rod 15-7.

[0035] A sliding rod 15-7 is fixed at the top of the lifting plate 15-4, and a matching sliding groove 15-8 is opened at the bottom of the rotating body 11. The sliding rod 15-7 slides in the sliding groove 15-8, which can play a good role in limiting and guiding the lifting plate 15-4 during the rising process, preventing the lifting plate 15-4 from tilting or shaking during the rising process, thereby ensuring the stability of the lifting of the hopper body 12.

[0036] Specifically, there are multiple sets of slide bars 15-7, which are evenly distributed on the top of the lifting plate 15-4.

[0037] Multiple sets of sliding rods 15-7 are evenly distributed on the top of the lifting plate 15-4, which further enhances the limiting and supporting effect of the lifting plate 15-4, making the lifting plate 15-4 more evenly stressed during the lifting process, better able to cope with various external force interferences during the lifting process, and ensuring that the hopper body 12 can be lifted stably.

[0038] Specifically, the fastener 32 includes a limiting ring 32-1 that is fixedly connected to the surface of the lifting plate 15-4 and cooperates with the limiting rod 31.

[0039] By cooperating with the limiting ring 32-1 and the limiting rod 31, the limiting rod 31 can be initially limited in the initial stage of the lifting plate 15-4's rise, preventing the hopper body 12 from shaking in the initial stage, providing a basic guarantee for subsequent fixing operations, and improving the reliability of equipment operation.

[0040] Specifically, a fixing groove 32-2 is provided on the surface of the limiting rod 31, and fixing blocks 32-3 are provided on both sides of the limiting rod 31, which cooperate with the fixing groove 32-2.

[0041] A fixing groove 32-2 is opened on the surface of the limiting rod 31, and a fixing block 32-3 that cooperates with the fixing groove 32-2 is set. When the fixing block 32-3 is engaged with the fixing groove 32-2, the limiting rod 31 can be further limited, which enhances the fixing effect on the hopper body 12 and effectively prevents the hopper from being displaced due to external force disturbance during the lifting process.

[0042] Specifically, a guide rod 32-4 is fixedly connected to one side of the fixed block 32-3, and a guide rail 32-5 is slidably connected to the surface of the guide rod 32-4 and fixedly connected to the rotating body 11.

[0043] The guide rod 32-4 fixed on one side of the fixed block 32-3 is slidably connected to the guide rail 32-5, and the guide rail 32-5 is fixedly connected to the rotating body 11. This structural design allows the fixed block 32-3 to move precisely along the direction of the guide rail 32-5 during the movement, ensuring that the fixed block 32-3 can accurately engage with the fixed groove 32-2, thus improving the accuracy and reliability of the fixing operation.

[0044] Specifically, the bottom of the fixed block 32-3 is fixedly connected to the connecting block 32-6, and the top of the lifting plate 15-4 is provided with a connecting groove 32-7, which cooperates with the connecting block 32-6.

[0045] The connection between the connecting block 32-6 and the connecting groove 32-7 can limit and support the fixing block 32-3, thereby enhancing the connection stability between the fixing block 32-3 and the lifting plate 15-4.

[0046] Specifically, the docking plate 22 is L-shaped and symmetrically distributed within the cavity of the rotating body 11.

[0047] The docking plate 22 is L-shaped and symmetrically distributed in the inner cavity of the rotating body 11. Its transverse groove and longitudinal groove cooperate with the docking block 21 when the hopper is pushed in and when it rises. This unique shape design can better cooperate with the docking block 21, providing transverse guidance when the hopper body 12 is pushed into the rotating body 11 and longitudinal guidance when it rises, ensuring that the hopper body 12 can be accurately installed in place, thus improving the assembly efficiency and accuracy of the equipment.

[0048] Working principle: First, the hopper body 12 is pushed into the rotating body 11. At this time, the docking blocks 21 on the top of both sides of the hopper body 12 will enter the docking plates 22 that are L-shaped and symmetrically distributed on both sides of the inner cavity of the rotating body 11. Due to the L-shaped design and symmetrical distribution of the docking plates 22, they play a precise guiding role in pushing the hopper body 12 in. As the hopper body 12 goes deeper, the docking block 21 moves laterally and comes into contact with the side wall of the docking plate 22. At this time, the card seats 24 around the top of the hopper body 12 will align with the card blocks 25 at the top of the inner cavity of the rotating body 11, further ensuring the positional accuracy of the hopper body 12 within the rotating body 11 and overcoming the problem of easy deviation in the docking position of the snap-fit ​​structure in the prior art. At the same time, the lifting blocks 15-5 at the bottom of both sides of the hopper body 12 will enter the lifting grooves 15-6 opened on the surface of the lifting plate 15-4, and the limiting rods 31 on the surface of the hopper body 12 will enter the limiting rings 32-1 fixed on the surface of the lifting plate 15-4. Subsequently, the second motors 15-1 on both sides of the top of the rotating body 11 are turned on. The output shaft of the second motor 15-1 drives the lead screw 15-2 to rotate. Since the lead screw 15-2 is threadedly connected to the threaded sleeve 15-3, the threaded sleeve 15-3 will drive the lifting plate 15-4 to move upward. During the ascent of the lifting plate 15-4, the slide rod 15-7 fixed at the top of the lifting plate 15-4 will slide within the slide groove 15-8 opened at the bottom of the rotating body 11, which will limit and support the lifting plate 15-4 and ensure that the lifting plate 15-4 rises smoothly. At the same time, the rise of the lifting plate 15-4 will cause the guide rod 32-4 to move the fixing block 32-3 towards the fixing groove 32-2 under the guidance of the guide rail 32-5, until the two sets of fixing blocks 32-3 are engaged with the fixing groove 32-2, thereby limiting the limit rod 31 and further fixing the hopper body 12. This overcomes the risk that the hopper may shake, deviate or even fall off during the lifting process due to external force disturbance or mechanical error in the prior art. Driven by the first motor inside the housing 14, the robotic arms 13 on both sides of the rotating body 11 can perform corresponding actions according to actual work requirements, cooperating with the entire mixer's workflow.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
