Description

Technical Field

[0001] This utility model relates to the technical field of grain weighing equipment, and more specifically, to a fast grain automatic weighing scale. Background Technology

[0002] In the grain processing and agricultural production sectors, the widespread application of grain threshers has significantly improved production efficiency. However, the supporting weighing equipment has long faced technological bottlenecks. Traditional grain weighing methods rely on manual operation, including multiple steps such as bagging, handling, weighing, and loading. This not only consumes a large amount of labor but is also prone to weighing errors due to human factors. In recent years, automatic weighing scales have emerged on the market, which can improve efficiency and reduce manual intervention to some extent. However, they have poor adaptability to external environments, especially under wind interference or human impact, making it difficult to guarantee weighing accuracy. This uncontrollability of external factors has become a major obstacle to the further promotion of automatic weighing scales. In addition, existing equipment also has shortcomings in terms of mobility and ease of operation, such as the need for frequent battery handling and the lack of protective design in the control box. These problems further limit the applicability of the equipment and the user experience.

[0003] From a technical perspective, the main reason why the industry has not yet effectively solved the above problems is that achieving high-precision weighing while simultaneously ensuring anti-interference capabilities and equipment portability involves comprehensive optimization across multiple aspects, including mechanical structure design, automated control, and material selection, making it technically challenging. At the same time, the industry's investment in the research and development of intelligent and integrated solutions is relatively insufficient, resulting in slow technological progress. From an international perspective, there is currently no automatic weighing device on the market that can comprehensively solve the above problems; therefore, this technological gap urgently needs to be filled.

[0004] This utility model addresses the shortcomings of existing technologies by proposing an integrated automatic grain weighing scale, which significantly improves the equipment's anti-interference capability and ease of operation through innovative design. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic grain weighing scale includes an outer frame, surrounding panels, and a bottom frame. The bottom frame is welded to the bottom of the outer frame. Surround panels are installed around the four sides of the outer frame, and an openable rear door is installed at the rear. Casters are mounted on the front end of the bottom frame. Manually adjustable support legs are located at the two corners of the rear end of the bottom frame, with casters at their bottoms.

A traction pin for traction is located at the end of the traction rod. A crossbeam frame is located inside the bottom frame near the rear end, and an integrated hanging bracket is fixed on the crossbeam frame. The upper end of the integrated hanging bracket is fixedly connected to the outer frame. A liftable lifting bracket is fitted on the integrated hanging bracket. The inner end of the traction beam is fixedly connected to the crossbeam frame. A hand-cranked jack is fixedly installed on the upper side of the traction beam. A lifting connecting plate is fixedly connected to the upper end of the hand-cranked jack. The lower end of the lifting connecting plate is welded to the lifting bracket. A support frame is provided inside the outer frame near the front side. Two sets of support frames are symmetrically welded to the bottom of the support frame. A fixed frame is provided on the upper side of the support frame. A weighing scale is welded and fixed on the upper side of the fixed frame. The lifting bracket is connected to the fixed frame and the support frame respectively through two sets of connecting mechanisms.

[0008] Furthermore, the connecting mechanism includes two sets of crossbars, two sets of connecting plates, slots, and two sets of end baffles. The two sets of connecting plates are respectively fixed on the left and right sides of the lifting bracket. Each set of connecting plates has two sets of slots, and two sets of crossbars are respectively locked inside the slots. The crossbars are hung on the connecting plates through the slots. Both ends of the two sets of crossbars are fixedly connected to the end baffles. The two sets of end baffles in the upper connecting mechanism are fixedly connected to the fixed frame, and the two sets of end baffles in the lower connecting mechanism are fixedly connected to the support frame.

[0009] Furthermore, a correction piece is provided on the inner side of the end baffle connected to the fixed frame and the upper crossbar, and a correction piece is also provided on the outer side of the corresponding connecting plate. The correction piece is a triangular structure, and one side of the long side of two adjacent sets of correction pieces is attached to each other.

[0010] Furthermore, the integrated bracket has a limiting plate perpendicular to it in the middle position inside, the outer end of the limiting plate extends towards the weighing scale, and its bottom has a groove that matches the crossbar.

[0011] Furthermore, positioning angle irons adapted to the fixed frame are fixed at the two corners on the left side of the upper end of the support frame, and the corners of the fixed frame are located inside the positioning angle irons.

[0012] Furthermore, the upper surface of the traction beam has multiple sets of positioning holes, and the traction rod is adjustablely connected to the traction beam through a pin engaging with the multiple sets of positioning holes.

[0013] Furthermore, an opening and closing cover is provided at the upper right corner of the right-side enclosure, and a controller for controlling the weighing scale is installed on the inner side of the enclosure at a position corresponding to the opening and closing cover.

[0014] Furthermore, a battery fixing plate for placing the battery is fixed in the area between the bottom frame and the crossbeam frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model achieves overall protection of the weighing scale by using an outer frame and a surrounding panel. The overall enclosure design effectively prevents the impact of wind and human collisions, ensuring the stable operation of the weighing scale and improving weighing accuracy. At the same time, the integrated outer frame structure design improves overall stability.

[0017] 2. This utility model, through the setting of movable wheels in conjunction with traction rods and traction pins, facilitates the connection of the device with external traction equipment, realizing the traction and movement of the entire device. At the same time, the setting of manual lifting outriggers facilitates the control of the overall height of the device and provides stable support for the device during weighing, improving the stability of the device. In addition, the casters set at the bottom of the manual lifting outriggers can work with the movable wheels to enable convenient short-distance movement of the device, making it easy to adjust the overall position of the device.

[0018] 3. The hand-cranked jack and connecting mechanism in this utility model make the height adjustment, installation and disassembly of the weighing scale easier, reduce the difficulty of operation and improve work efficiency. This design facilitates the height adjustment of the weighing scale. When weighing grain, the height of the weighing scale can be lowered so that the support frame is on the ground, achieving stable support for the weighing scale and ensuring the accuracy of the weighing process. After weighing, the weighing scale can be raised again to facilitate subsequent traction and movement.

[0019] 4. In this utility model, a corrective plate is provided on the inner side of the end baffle connected to the fixed frame and the upper crossbar, and a corresponding corrective plate is also provided on the outer side of the connecting plate. The corrective plate has a triangular structure, and the long side of adjacent sets of corrective plates is fitted together. During the operation of the automatic weighing scale, due to factors such as equipment vibration and the movement of the lifting bracket, deviations may occur at the connection between the integrated frame and the internal weighing scale. The triangular structure of the corrective plate can limit this deviation, and its long side fitting together can guide the crossbar to remain in the correct connection position, preventing the connection between the integrated frame and the internal weighing scale from shifting. This allows the weighing scale to be corrected during each lifting process, keeping it in the center position and effectively preventing the weighing scale from shifting. Attached Figure Description

[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 protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 6As shown, an automatic grain weighing scale includes an outer frame 2, surrounding panels 3, and a bottom frame 5. The outer frame 2 adopts an integrated structure, and the bottom frame 5 is welded to the bottom of the outer frame 2. The outer frame 2 and the bottom frame 5 work together to provide stable support for the entire device, ensuring the stability of the weighing scale 1. Surround panels 3 are installed on all four sides of the outer frame 2, and an openable rear door 8 is installed on the rear side. The surrounding panels 3 and the rear door 8 can seal off the outer frame 2, effectively preventing the effects of wind and human impact, ensuring the stable operation of the weighing scale 1, improving weighing accuracy, and at the same time, the openable rear door 8 facilitates the operation and maintenance of its internal equipment. The front end of the base frame 5 is equipped with casters 6, and both sides of the rear end of the base frame 5 are equipped with manually adjustable support legs 4. Casters 7 are mounted on the bottom of the manually adjustable support legs 4. This design allows the weighing scale 1 to be flexibly moved as needed. Once moved to a suitable position, the overall height of the device can be adjusted by adjusting the manually adjustable support legs 4, while simultaneously ensuring the casters 7 are supported on the ground, guaranteeing equipment stability and reducing the impact of shaking on weighing accuracy. A traction beam 23 is welded to the bottom right side of the base frame 5. An adjustable traction rod 10 is inserted inside the traction beam 23. A traction pin 24 for traction is located at the end of the traction rod 10. The traction rod 10 and traction pin 24 facilitate the connection of the device to external traction equipment for movement. The length of the traction rod 10 can be adjusted according to actual conditions to adapt to different traction needs. A crossbeam frame 15 is located near the rear end inside the base frame 5. An integrated hanger 20 is fixedly mounted on the crossbeam frame 15, and the upper end of the integrated hanger 20 is fixedly connected to the outer frame 2. A liftable lifting bracket 12 is fitted onto the integrated hanger 20. The crossbeam frame 15 provides a stable support foundation for the entire lifting system. The integrated hanger 20 connects the lifting bracket 12 to the outer frame 2, allowing the lifting bracket 12 to move stably during lifting operations. The inner end of the traction beam 23 is fixedly connected to the crossbeam frame 15. A hand-cranked jack 14 is fixedly mounted on the upper side of the traction beam 23. A lifting connecting plate 19 is fixedly connected to the upper end of the hand-cranked jack 14, and the lower end of the lifting connecting plate 19 is welded to the lifting bracket 12. By manually cranking the hand-cranked jack 14, the lifting connecting plate 19 and the lifting bracket 12 can be moved up and down, thereby adjusting the height of the weighing scale 1 to adapt to different usage scenarios and weighing needs, and improving the versatility of the equipment. Inside the outer frame 2, near the front, there is a support frame 17. Two sets of support frames 16 are symmetrically welded to the bottom of the support frame 17. A fixed frame 18 is provided on the upper side of the support frame 17. The weighing scale 1 is welded and fixed on the upper side of the fixed frame 18. The support frame 17 and the support frames 16 provide stable support for the fixed frame 18 and the weighing scale 1, ensuring the stability of the weighing scale 1 during operation.The lifting bracket 12 is connected to the fixed frame 18 and the support frame 17 respectively through two sets of connecting mechanisms 21. The connecting mechanism 21 realizes the fixed connection between the lifting bracket 12, the fixed frame 18 and the support frame 17, and thus realizes the lifting function of the fixed frame 18 and the support frame 17. This design solves the problems of the existing fast grain weighing scale 1 being easily affected by external factors, inconvenient to move and complicated to operate.

[0030] In this embodiment, the connecting mechanism 21 includes two sets of crossbars 211, two sets of connecting plates 212, slots 213, and two sets of end baffles 214. The two sets of connecting plates 212 are respectively fixed on the left and right sides of the lifting bracket 12. Each set of connecting plates 212 has two sets of slots 213. The connecting plates 212 and the lifting bracket 12 form a whole and can move synchronously with the movement of the lifting bracket 12, thereby driving the crossbars 211 to move up and down. Moreover, the design of the slots 213 provides precise positioning and fixing points for the installation of the crossbars 211, so that the crossbars 211 can be accurately installed in the designated position and ensure that they will not easily shift after installation. Two sets of crossbars 211 are respectively engaged in the two sets of slots 213. The crossbars 211 are hung on the connecting plate 212 through the slots 213. As a key force-bearing component in the connecting mechanism 21, the crossbars 211 are responsible for transmitting the movement and force of the lifting bracket 12, and transmitting the lifting movement of the lifting bracket 12 to the fixed frame 18 and the support frame 17. Both ends of the two sets of crossbars 211 are fixedly connected to the end baffles 214. The two sets of end baffles 214 in the upper connecting mechanism 21 are fixedly connected to the fixed frame 18, and the two sets of end baffles 214 in the lower connecting mechanism 21 are fixedly connected to the support frame 17. The end baffles 214 act as a bridge connecting the crossbars 211 with the fixed frame 18 and the support frame 17, transmitting the force borne by the crossbars 211 to the fixed frame 18 and the support frame 17, and also restricting the axial movement of the crossbars 211 to ensure the reliability of the connection. The connecting mechanism 21 facilitates the connection between the lifting bracket 12 and the fixed frame 18 and the support frame 17, ensuring that the fixed frame 18 and the support frame 17 can move synchronously with the movement of the lifting bracket 12 and guaranteeing the stability of the lifting. At the same time, the crossbar 211 is hung on the connecting plate 212 through the slot 213, making the connection mechanism 21 detachable from the fixed frame 18 and the support frame 17, which is convenient for installation and subsequent disassembly and maintenance.

[0031] In this embodiment, a correction piece 22 is provided on the inner side of the end baffle 214 connected to the fixed frame 18 at the connection point with the upper crossbar 211, and a corresponding correction piece 22 is also provided on the outer side of the connecting plate 212. The correction piece 22 has a triangular structure, and the long side of two adjacent sets of correction pieces 22 are fitted together. During the operation of the automatic weighing scale, due to factors such as equipment vibration and the movement of the lifting bracket 12, deviations may occur at the connection point between the integrated bracket 20 and the internal weighing scale 1. The triangular structure of the correction piece 22 can limit such deviations, and its long side fitting together can guide the crossbar 211 to remain in the correct connection position, preventing the connection point between the integrated bracket 20 and the internal weighing scale 1 from shifting. This allows the position of the weighing scale 1 to be corrected during each lifting process, keeping it in the center position and effectively preventing the weighing scale 1 from shifting.

[0032] In this embodiment, a limiting plate 26 perpendicular to the integrated bracket 20 is provided in the middle of the integrated bracket 20. The outer end of the limiting plate 26 extends towards the weighing scale 1, and its bottom has a slot adapted to the crossbar 211. During the operation of the automatic grain weighing scale, the lifting bracket 12 drives the crossbar 211 to move. The slot of the limiting plate 26 plays a precise limiting role in the movement of the crossbar 211. When the crossbar 211 moves to a certain position, it will contact the slot and be restricted, thereby ensuring that the crossbar 211 moves within a reasonable range of motion, and thus limiting the height of the weighing scale 1 to prevent it from being too high and unstable, which would affect the weighing accuracy.

[0033] In this embodiment, positioning angle irons 25, adapted to the fixed frame 18, are fixed at both corners on the upper left side of the support frame 17, with the corners of the fixed frame 18 located inside the positioning angle irons 25. The positioning angle irons 25 serve to position the fixed frame 18. When the fixed frame 18 is installed onto the support frame 17, the positioning angle irons 25 provide guidance and positioning. Since the corners of the fixed frame 18 need to be placed inside the positioning angle irons 25, the operator only needs to align the corners of the fixed frame 18 with the positioning angle irons 25 to quickly and accurately place the fixed frame 18 in the correct position, greatly shortening the installation time and improving installation efficiency. Simultaneously, the positioning angle irons 25 restrict the horizontal movement of the fixed frame 18, making the connection between the fixed frame 18 and the support frame 17 more stable.

[0034] In this embodiment, the upper surface of the traction beam 23 has multiple sets of positioning holes, and the traction rod 10 is adjustablely connected to the traction beam 23 via pins that engage with these positioning holes. The pins engaging with the positioning holes ensure a stable connection between the traction rod 10 and the traction beam 23, while the multiple positioning holes provide several selectable fixing points for adjusting the position of the traction rod 10. When the position of the traction rod 10 needs to be adjusted, simply pull out the pins, move the traction rod 10 to the appropriate positioning hole position, and then insert the pins again to secure it. This connection method is simple, easy to implement, and convenient to operate, enabling rapid adjustment of the traction rod 10's position to adapt to different traction needs.

[0035] In this embodiment, a hinged cover 9 is provided at the upper right corner of the right-side enclosure 3. A controller 11 for controlling the weighing scale 1 is installed on the inner side of the enclosure 3 at a position corresponding to the hinged cover 9. This corresponding installation design allows the controller 11 to be directly exposed after the hinged cover 9 is opened, facilitating the operator to debug, maintain, and operate the controller 11, thus improving the ease of use of the equipment. At the same time, the hinged cover 9 is normally closed, which can protect the controller 11.

[0036] In this embodiment, a battery fixing plate 13 for placing batteries is fixed in the area between the bottom frame 5 and the crossbeam frame 15. The battery fixing plate 13 provides a dedicated storage space for the batteries, allowing users to fix the batteries in the battery fixing plate 13 for convenient subsequent use without repeatedly moving external batteries. At the same time, the battery fixing plate 13 can effectively protect the batteries from damage caused by the external environment.

[0037] It should be noted that the manual lifting outrigger 4, the hand-cranked jack 14, and the weighing scale 1 are all existing technology products. Their specific structural features and working principles are all existing technologies, so they will not be described in detail here.

[0038] The working principle of this automatic weighing scale for fast food:

[0039] The automatic weighing scale relies on the stable structure formed by the outer frame 2 and the bottom frame 5 for support. The integrated design of the outer frame 2 and its welded connection with the bottom frame 5 ensure the overall rigidity of the device, providing a foundation for the stable operation of the weighing scale 1. The enclosure 3 and the rear door 8 enclose the outer frame 2 to reduce interference from external factors such as wind and human impact during the weighing process, thereby ensuring that the weighing scale 1 can work in a relatively stable environment and improve weighing accuracy.

[0040] The movable wheels 6 on the front and rear sides of the left end of the base frame 5 and the casters 7 at the bottom of the manually adjustable support legs 4 at the corners of the rear end of the base frame 5 enable the weighing scale 1 to move flexibly. When the weighing scale 1 needs to be moved, a traction pin 24 connected to the end of the traction beam 23 is used for traction. The traction pin 24 is connected to the traction rod 10, which can be extended and retracted within the traction beam 23 to adapt to different traction needs. Under the action of traction force, the movable wheels 6 and casters 7 roll, moving the entire device to the designated position. After moving to the appropriate position, the manually adjustable support legs 4 are adjusted. Adjusting the manually adjustable support legs 4 changes the overall height of the device, while simultaneously ensuring that the casters 7 are supported on the ground. By reasonably adjusting the height of each manually adjustable support leg 4, the device is ensured to be placed horizontally, reducing the impact of shaking on the weighing accuracy. At this time, the device is stably supported on the ground by the manually adjustable support legs 4 and casters 7.

[0041] A manual crank jack 14 is fixed to the upper side of the traction beam 23. During operation, the manual crank jack 14 generates an upward lifting force, which is transmitted to the lifting connecting plate 19, which is fixedly connected to the upper end of the manual crank jack 14. The lower end of the lifting connecting plate 19 is welded to the lifting bracket 12, so the lifting force generated by the manual crank jack 14 causes the lifting connecting plate 19 and the lifting bracket 12 to move up and down together. The crossbeam frame 15 provides a stable support foundation for the entire lifting system. The integrated bracket 20 connects the lifting bracket 12 to the outer frame 2, allowing the lifting bracket 12 to move stably during lifting operations. The lifting bracket 12 is connected to the fixed frame 18 and the support frame 17 respectively through two sets of connecting mechanisms 21. The connecting plate 212 in the connecting mechanism 21 is fixed to the lifting bracket 12. The crossbar 211 is hung on the connecting plate 212 through the slot 213. The two ends of the crossbar 211 are fixedly connected to the fixed frame 18 and the support frame 17 respectively through the end baffles 214. When the lifting bracket 12 moves up and down, it will drive the crossbar 211 to move up and down in the slot 213 of the connecting plate 212. Then, the motion is transmitted to the fixed frame 18 and the support frame 17 through the end baffles 214, realizing the lifting function of the fixed frame 18 and the support frame 17, thereby adjusting the height of the weighing scale 1 to adapt to different usage scenarios and weighing needs.

[0042] During the operation of the automatic grain weighing scale, due to factors such as equipment vibration and the movement of the lifting bracket 12, the connection between the crossbar 211 and the connecting plate 212 may shift. Correcting plates 22 are provided on the inner side of the connection between the end baffle 214 (connected to the fixed frame 18) and the upper crossbar 211, as well as on the corresponding outer side of the connecting plate 212. The correcting plates 22 have a triangular structure, with one side of the long side of adjacent sets of correcting plates 22 fitting together. When the connection of the crossbar 211 shifts, the triangular structure of the correcting plates 22 can limit this shift, and the fitting of their long sides can guide the crossbar 211 to remain in the correct connection position, preventing lateral or longitudinal shifts at the connection and ensuring the stability of the connection structure.

[0043] A limiting plate 26 is located in the middle of the integrated bracket 20. The outer end of the limiting plate 26 extends towards the weighing scale 1, and its bottom has a slot that matches the crossbar 211. During the movement of the crossbar 211 driven by the lifting bracket 12, when the crossbar 211 moves to a certain position, it will contact the slot of the limiting plate 26 and be restricted, thereby ensuring that the crossbar 211 moves within a reasonable range of motion. This limits the height of the weighing scale 1, preventing it from being too high and unstable, which would affect the weighing accuracy.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
