Description

Technical Field

[0001] This utility model relates to the technical field of material weighing, specifically a suspended material tower weighing system. Background Technology

[0002] In order to achieve precise quantitative feeding, modern farms usually need to install a weighing system on the feed tower to weigh the feed tower. The weighing system is connected to the Internet and computers, so that the weight of the feed tower can be detected in real time and the feed can be automatically dispensed in quantitative form.

[0003] Each leg of the suspended material tower is equipped with a weighing system, which includes a support frame that is installed on the ground. Sensors are suspended on the support frame, and a connecting structure is usually installed below the sensor to connect the material cylinder legs.

[0004] Chinese Utility Model Publication No. CN 220583576 U discloses a suspended weighing device for a material tower, its connector and the material tower, wherein the connector is suitable for connecting a profile support leg made of a bent plate; Chinese Utility Model Publication No. CN216433218 U discloses a lifting suspended weighing device with a columnar sensor, wherein the connector is suitable for connecting a square support leg.

[0005] Suspended silos sometimes use circular steel pipes to make support legs. There are some existing solutions to connect circular steel pipe support legs, but the connection between the circular steel pipe support legs and the connectors is often unstable, causing the silos to shake easily, resulting in inaccurate weighing and even damage to the sensors. Utility Model Content

[0006] The problem to be solved by this utility model is to provide a suspended material tower weighing system and its connection structure and suspended material tower, which is adapted to circular steel pipe legs and can be stably connected to the legs to reduce shaking.

[0007] To solve the above-mentioned technical problems, the connection structure of the suspended material tower weighing system of this utility model includes an installation part and a connecting part. The installation part is used to install the connecting structure at the bottom of the sensor of the weighing system; the connecting part is integrally connected to the installation part and is used to connect the support legs of the suspended material tower. The connecting part includes an integrally formed middle support plate, a left support plate, and a right support plate. At least one transverse support bolt is provided between the left support plate and the right support plate, and the two ends of the transverse support bolt are respectively movably mounted on the left support plate and the right support plate; when the connecting part is connected to the support leg, the transverse support bolt passes through the support leg, so that the transverse support bolt provides support for the support leg.

[0008] By adopting the above technical solution, the suspended material tower weighing system of this utility model can drill matching screw holes on the cylindrical support legs, through which the transverse support bolts pass, and the transverse support bolts bear the weight of the support legs and the material tower. At the same time, the middle support plate, left support plate and right support plate can support the outer wall of the cylindrical support legs from three directions.

[0009] Because the horizontal support bolts need to be fitted with the bolt holes on the legs for easy installation, there is a gap between the legs and the horizontal support bolts. This can cause shaking when the silo is loading or unloading materials.

[0010] To address this issue, further improvements were made by installing at least one longitudinal support bolt on the middle support plate. The inner end of the longitudinal support bolt is movably mounted on the middle support plate, and a movable positioning block is installed on the outer end of the longitudinal support bolt. When the connecting part is connected to the outrigger, the longitudinal support bolt passes through the outrigger, and then the movable positioning block is installed on the outer end of the longitudinal support bolt, so that the longitudinal support bolt provides support for the outrigger.

[0011] By adopting the above technical solution, the transverse support bolts are first installed, then the longitudinal support bolts are inserted, and finally the movable positioning block is installed on the longitudinal support bolts. The nut is tightened on the outside of the movable positioning block, so that the movable positioning block applies pressure to the outrigger, thereby making the outrigger immobile in the longitudinal direction. This effectively solves the problem of swaying caused by the gap between the transverse bolts and the outrigger.

[0012] Preferably, the movable positioning block includes two side wings in a V-shape, and the movable positioning block is mounted on the longitudinal support bolt by fastening bolts. This structure allows the two side wings of the movable positioning block to clamp the support leg from both sides, and the movable positioning block can accommodate support legs of different diameters.

[0013] The transverse support bolts are perpendicular or substantially perpendicular to the longitudinal support bolts. Orthogonal installation of the transverse and longitudinal support bolts results in a more reasonable constraint on the outriggers by the two support bolts.

[0014] As a further improvement, the middle support plate, left support plate and right support plate are curved on one side where they meet the support leg.

[0015] As a further improvement, the middle support plate, left support plate and right support plate are joined to the legs on one side in a semi-circular arc shape.

[0016] The arc or rounded contact surface allows for a larger contact area between the connecting structure and the outrigger, resulting in a tighter fit and better preventing wobbling.

[0017] As a further improvement, the middle support plate, left support plate and right support plate form a multi-segment arc on one side where they connect with the support leg. The multi-segment arc includes a middle segment and at least one side segment. The side segment includes two symmetrical left and right parts. The radius of the arc of the middle segment is R1, and the radius of the arc of the side segment is R2, where R2 > R1.

[0018] A small-radius arc is set in the middle section to accommodate thin cylindrical legs, while symmetrical two-sided arcs are set on the two outer sides of the middle arc to accommodate thicker cylindrical legs. The outer sides of the thicker cylindrical legs can abut against these two arcs, making the contact of the cylindrical legs more stable.

[0019] Furthermore, the multi-segment arc includes a middle segment, first side segments, and second side segments. The radius of the arc of the first side segments is R2, and the radius of the arc of the second side segments is R3, where R3 > R2. This allows the second side segments to accommodate thicker support legs.

[0020] This utility model also relates to a suspended material tower weighing system, including a support frame, on which a sensor is suspended, and a connecting structure is installed below the sensor. The connecting structure is used to connect the material cylinder support leg, and the connecting structure is the aforementioned connecting structure.

[0021] This utility model also relates to a material tower, including a material cylinder and support legs. The material cylinder is used to store materials, and the support legs are used to support the material cylinder. The bottom of the support legs is installed on a weighing system, so that the weighing system can weigh the material cylinder and the support legs. The weighing system is the above-mentioned suspended material tower weighing system.

[0022] With this structure, the floating tower weighing system of this utility model first installs the transverse support bolts, then inserts the longitudinal support bolts, and finally installs the movable positioning block on the longitudinal support bolts. The nut is tightened on the outside of the movable positioning block, so that the movable positioning block applies pressure to the support leg, thereby making the support leg immobile in the longitudinal direction. This effectively solves the problem of swaying caused by the gap between the transverse floating tower weighing system and the support leg.

[0041] like Figure 1 and Figure 2 As shown, the material tower of this utility model includes a material cylinder 1 and a support leg 2. The material cylinder 1 is used to store materials, and the support leg 2 is used to support the material cylinder 1. The bottom of the support leg 2 is installed on a weighing system 3, so that the weighing system 3 can weigh the material cylinder 1 and the support leg 2. The weighing system 3 is the suspended material tower weighing system described below.

[0042] like Figure 2 and Figure 3 As shown, the weighing system 3 of this utility model includes a support 4, on which a sensor 5 is suspended. A connecting structure is installed below the sensor 5. The connecting structure is used to connect the material cylinder support leg 2. The connecting structure is as follows.

[0043] The connection structure of the suspended material tower weighing system of this utility model includes an installation part 6 and a connecting part 7. The installation part 6 is used to install the connecting structure at the bottom of the sensor 5 of the weighing system; the connecting part 7 is integrally connected to the installation part 6 and is used to connect the support legs of the suspended material tower. The connecting part includes an integrally formed middle support plate 71, a left support plate 72, and a right support plate 73. At least one transverse support bolt 8 is provided between the left support plate 72 and the right support plate 73. The two ends of the transverse support bolt 8 are respectively movably installed on the left support plate 72 and the right support plate 73; when the connecting part 7 is connected to the support leg 2, the transverse support bolt 8 passes through the support leg 2, so that the transverse support bolt 8 provides support for the support leg.

[0044] By adopting the above technical solution, the floating tower weighing system of this utility model can drill matching screw holes on the cylindrical support leg 2, and pass the transverse support bolt 8 through the support leg 2. The transverse support bolt 8 bears the weight of the support leg 2 and the tower. At the same time, the middle support plate 71, the left support plate 72 and the right support plate 73 can support the outer wall of the cylindrical support leg 2 from three directions.

[0045] To facilitate the installation of the transverse support bolts 8, the bolt holes on the legs 2 generally require clearance fit. There are also gaps between the legs 2 and the transverse support bolts 8, and between the legs 2 and the connecting part 7, making it impossible to fit tightly. In addition, the legs 2 and the transverse support bolts 8 can rotate, which will cause shaking and noise when the material tower is loading or unloading materials.

[0046] To address this issue, further improvements were made. A longitudinal support bolt 9 was installed in the screw hole at the center of the middle support plate 71. Multiple longitudinal support bolts can also be installed. The inner end of the longitudinal support bolt 9 is movably mounted on the middle support plate 71, and a movable positioning block 10 is installed on the outer end of the longitudinal support bolt 9. When the connecting part 7 is connected to the support leg 2, the longitudinal support bolt 9 passes through the support leg 2, and then the movable positioning block 10 is installed on the outer end of the longitudinal support bolt 9. The longitudinal support bolt 9 provides support for the support leg 2.

[0047] By adopting the above technical solution, the transverse support bolt 8 is first installed, then the longitudinal support bolt 9 is inserted, and finally the movable positioning block 10 is installed on the longitudinal support bolt 9. The fastening nut 11 is installed on the outside of the movable positioning block, so that the movable positioning block 10 applies pressure to the support leg 2, squeezing the gap between each component, thereby making the support leg immovable in the longitudinal direction, effectively solving the problem of swaying caused by the gap between the transverse bolt and the support leg.

[0048] The movable positioning block 10 includes two side wings 101, which are V-shaped. The movable positioning block 10 is mounted on the longitudinal support bolt 9 by fastening nuts 11. This structure allows the two side wings 101 of the movable positioning block 10 to clamp the support leg 2 from both sides. The movable positioning block 10 can adapt to support legs of different diameters, reducing noise and increasing service life.

[0049] The transverse support bolt 8 is perpendicular or substantially perpendicular to the longitudinal support bolt 9, with a distance between them, preferably 10-20% of the bolt length. Orthogonal installation of the transverse and longitudinal support bolts ensures a more reasonable constraint on the support leg. First, after installing the transverse support bolt 8, it bears the weight of the support leg 2 and the material tower 1. Then, the longitudinal support bolt 9 is installed, its inner end connected to the screw hole in the middle of the central support plate 71, also bearing the weight of the support leg 2 and the material tower 1. Finally, the fastening nut 11 is tightened, causing the support leg 2 to fit tightly against the connecting structure 7. The pressure between the support leg 2 and the connecting structure 7 generates significant friction, which also helps it bear weight.

[0050] To ensure a tighter fit between the outrigger 2 and the connecting part 7, the sides of the middle support plate 71, left support plate 72, and right support plate 73 that connect with the outrigger 2 are curved. Alternatively, the sides of the middle support plate, left support plate, and right support plate that connect with the outrigger are semi-circular. Since the cross-section of the outrigger 2 is generally circular, the curved or arc-shaped contact surface allows for a larger contact area between the connecting structure 7 and the outrigger 2, resulting in a tighter fit and better preventing wobbling.

[0051] As a further improvement, the middle support plate 71, the left support plate 72 and the right support plate 73 form a multi-segment arc on one side where they connect with the support leg. The multi-segment arc includes a middle segment 12 and at least one side segment 13. The side segment 13 includes two symmetrical left and right parts. The radius of the arc of the middle segment 12 is R1, and the radius of the arc of the side segment 13 is R2, where R2 > R1.

[0052] A small-radius arc is set in the middle part to accommodate thin cylindrical legs 2. Symmetrical two-sided arcs 13 are set on the two outer sides of the arc of the middle section 12 to accommodate thicker cylindrical legs. The outer side of the thicker cylindrical legs can abut against these two arcs, making the contact of the cylindrical legs more stable.

[0053] Furthermore, the multi-segment arc includes a middle segment 12, first two side segments 13, and second two side segments 14. The radius of the arc of the first two side segments is R2, and the radius of the arc of the second two side segments is R3, where R3 > R2. In this way, the second two side segments 14 can accommodate thicker support legs.

[0054] Currently, the commonly used radii for outrigger 2 are generally 40mm, 50mm, and 60mm. To accommodate these outriggers, the multi-segment arc is set to three segments. When using an outrigger with a radius of 40mm, outrigger 2 fits onto the middle segment 12; when using an outrigger with a radius of 50mm, outrigger 2 fits onto the first two side segments 13. In this way, the two arc segments of the first two side segments 13 and the two side wings 101 of the positioning block 10 fit onto the outrigger 2 from four directions, thus preventing the outrigger 2 from wobbling. When using an outrigger with a radius of 60mm, outrigger 2 fits onto the second two side segments 14.

[0055] In actual use, outrigger 2 is usually made of steel pipe, such as Figure 9 As shown.

[0056] With this structure, the floating tower weighing system of this utility model first installs the transverse support bolts, then inserts the longitudinal support bolts, and finally installs the movable positioning block on the longitudinal support bolts. The nut is tightened on the outside of the movable positioning block, so that the movable positioning block applies pressure to the support leg, thereby making the support leg immobile in the longitudinal direction. This effectively solves the problem of swaying caused by the gap between the transverse floating tower weighing system and the support leg.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall fall within the protection scope of the present utility model.
