Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting, and in particular to a weighing platform and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology.

[0003] Fruits and vegetables are generally sorted based on multiple criteria such as weight, surface abrasion, and fruit sweetness. After sorting, the fruits and vegetables undergo weighing, labeling, and packaging. These operations require operators to place the fruits and vegetables output from the conveyor line onto a weighing platform for weighing and packaging.

[0004] However, current weighing platforms cannot be adapted to the height of different fruit and vegetable conveyor lines. Moreover, the height of operators varies, and a single-size weighing platform cannot be used, thus affecting the weighing and packaging efficiency of fruits and vegetables. Utility Model Content

[0005] The present invention aims to provide a weighing platform and a fruit and vegetable sorting machine to solve the technical problem that the weighing platform in the prior art cannot be adapted to the height of different fruit and vegetable conveyor lines or to the height of different operators.

[0006] To solve the above-mentioned technical problems, this utility model embodiment provides a weighing platform, including:

[0007] The base has a sliding cavity, which is arranged in a vertical direction;

[0008] A lifting frame, one end of which is housed in the sliding cavity, and the lifting frame is slidably connected to the base;

[0009] An adjustment assembly, which is connected to the lifting frame and the base;

[0010] An electronic scale is mounted on the lifting frame. The adjusting component can adjust the lifting frame to slide vertically relative to the base, thereby driving the electronic scale to move vertically.

[0011] With the above structure, the lifting frame is vertically adjusted along the sliding cavity using the adjustment component, and the electronic scale moves vertically along with the lifting frame, adjusting the height of the electronic scale to adapt to the actual working conditions.

[0012] In some embodiments, the adjustment assembly includes a first adjustment bracket, a second adjustment bracket, and a rotating shaft. The rotating shaft passes through the middle of the first adjustment bracket and the middle of the second adjustment bracket, so that the first adjustment bracket and the second adjustment bracket are rotatably connected. The first adjustment bracket is inclined relative to the horizontal plane, and the first adjustment bracket and the second adjustment bracket are arranged crosswise. The lifting frame has a first sliding groove, which is horizontally arranged. Two first sliding grooves are located on opposite sides of the lifting frame and are arranged opposite each other. One end of the first adjustment bracket is slidably received in the two first sliding grooves on opposite sides, and the other end of the first adjustment bracket is rotatably connected to the base. The base has a second sliding groove, which is horizontally arranged. Two second sliding grooves are located on opposite sides of the lifting frame and are arranged opposite each other. Each second sliding groove is located on the same side as a corresponding first sliding groove. One end of the second adjustment bracket is slidably received in the two second sliding grooves on opposite sides, and the other end of the second adjustment bracket is rotatably connected to the lifting frame.

[0013] Through the above structure, the first adjusting bracket is driven to rotate relative to the second adjusting bracket. If the end of the first adjusting bracket near the lifting frame is close to the second adjusting bracket, the tilt angle of the first adjusting bracket increases. Specifically, the end of the first adjusting bracket near the lifting frame moves upward and drives the lifting frame to move upward along the sliding cavity, so as to achieve the function of adjusting the height of the lifting frame.

[0014] In some embodiments, a first sliding wheel is installed at the end of the first adjusting bracket near the lifting frame, the first sliding wheel being received in the first sliding groove and capable of sliding within the first sliding groove; a second sliding wheel is installed at the end of the second adjusting bracket near the base, the second sliding wheel being received in the second sliding groove and capable of sliding within the second sliding groove.

[0015] The above structure modifies sliding friction into rolling friction to avoid wear on the ends of the first and second adjusting brackets.

[0016] In some embodiments, the adjustment assembly further includes a handle, an adjustment screw, a screw nut, and a linkage rod. The adjustment screw is rotatably mounted on the lifting frame and is placed horizontally. The handle is connected to one end of the adjustment screw. The screw nut is sleeved on the adjustment screw. One end of the linkage rod is rotatably connected to the screw nut, and the other end is rotatably connected to the first adjustment bracket.

[0017] The above structure employs an adjusting screw to improve adjustment accuracy, precisely adjusting the height of the lifting platform and electronic scale when they are raised or lowered.

[0018] In some embodiments, the weighing platform further includes a mounting plate, which is mounted on one end of the first adjusting bracket near the base. The mounting plate includes a base portion and a snap-fit ​​portion. Two snap-fit ​​portions are provided, which are connected to opposite sides of the base portion. The two snap-fit ​​portions are horizontally placed and have a gap between them. The two snap-fit ​​portions and the base portion enclose each other to form a snap-fit ​​groove, which is used to snap the base. The end of the first adjusting bracket near the base is hinged to the base portion.

[0019] With the above structure, the two snap-fit ​​parts and the base part surround to form a snap-fit ​​groove, and part of the base is received in the snap-fit ​​groove so that the mounting plate snaps into the base; the first adjustment bracket is hinged to the base part so that the first adjustment bracket can rotate relative to the base.

[0020] In some embodiments, the base includes a first vertical rod, a first horizontal rod, and a second horizontal rod. There are four first vertical rods arranged in a matrix. Two first horizontal rods are horizontally arranged along the length of the base, with one connecting between two corresponding first vertical rods. A snap-fit ​​groove engages one of the first horizontal rods. Two second horizontal rods are horizontally arranged along the width of the base, with one connecting between two corresponding first vertical rods. The second horizontal rod has a second sliding groove, and each first vertical rod has a sliding cavity.

[0021] The lifting frame includes a second vertical rod, a third horizontal rod, a fourth horizontal rod, and a cover plate. There are four second vertical rods, one end of which is connected to one of the four corners of the cover plate. The other end of each second vertical rod is slidably connected to a corresponding first vertical rod. Two third horizontal rods are arranged horizontally along the length of the lifting frame, with one connecting between two corresponding second vertical rods. Two fourth horizontal rods are arranged horizontally along the width of the lifting frame, with one connecting between two corresponding second vertical rods. The fourth horizontal rod has a first sliding groove. The electronic scale is located on the side of the cover plate facing the base.

[0022] With the above structure, the four second vertical rods support the four corners of the cover plate respectively. The second vertical rods support the cover plate, ensuring that the cover plate is set horizontally, and further ensuring that the reading of the electronic scale on the cover plate is more accurate.

[0023] In some embodiments, the weighing platform further includes a support frame connected to the side of the cover plate facing the base, with opposite ends of the support frame connected to opposite sides of the cover plate, and the electronic scale mounted on the support frame such that the end of the electronic scale facing away from the support frame abuts against the cover plate.

[0024] With the above structure, when a heavy object is placed on the end face of the cover plate away from the base, the end face of the cover plate deforms. The sensor inside the electronic scale receives the deformation signal and feeds it back as a digital signal for display.

[0025] In some embodiments, the weighing platform further includes a fixing plate connected to one end of the base away from the lifting frame. The base has a locking hole for fixing and locking the base.

[0026] With the above structure, the fixing plate has locking holes, through which fasteners such as bolts or screws are passed to fix the first vertical rod, which facilitates quick installation and disassembly of the base.

[0027] In some embodiments, the weighing platform further includes a cover, which is detachably connected to the end face of the lifting frame away from the base. The cover has a protective cavity with the opening of the protective cavity facing the end face of the lifting frame away from the base.

[0028] With the above structure, the cover protects the surface of the cover plate when the weighing platform is transferred, preventing dust from adhering to the end face.

[0029] This utility model also provides a fruit and vegetable sorting machine, including the weighing platform described in any of the above embodiments.

[0030] Compared with the prior art, in this embodiment of the utility model, the lifting frame is vertically adjusted along the sliding cavity by adjusting the component, and the electronic scale moves vertically with the lifting frame, adjusting the height of the electronic scale to adapt to the actual working conditions.

[0038] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a weighing platform provided in one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the base, lifting frame, adjustment components, and electronic scale of the weighing platform.

[0039] An embodiment of this utility model provides a weighing platform 100, including a base 10, a lifting frame 20, an adjusting component 30, and an electronic scale 40. The base 10 has a sliding cavity 11, which is arranged vertically. One end of the lifting frame 20 is housed in the sliding cavity 11, and the lifting frame 20 is slidably connected to the base 10. The adjusting component 30 is connected to the lifting frame 20 and the base 10. The electronic scale 40 is mounted on the lifting frame 20, and the adjusting component 30 can adjust the lifting frame 20 to slide vertically relative to the base 10, thereby driving the electronic scale 40 to move vertically.

[0040] Specifically, the base 10 is placed on the ground, the sliding cavity 11 is connected to the outside with its opening facing away from the ground, the bottom end of the lifting frame 20 is housed in the sliding cavity 11 and can slide along the cavity wall of the sliding cavity 11, the lifting frame 20 is vertically adjusted relative to the base 10 along the sliding cavity 11 using the adjustment component 30, the electronic scale 40 moves vertically with the lifting frame 20, and the height of the electronic scale 40 is adjusted to adapt to the actual working conditions.

[0041] In one embodiment, the adjustment assembly 30 includes a first adjustment bracket 31, a second adjustment bracket 32, and a rotating shaft 33. The rotating shaft 33 passes through the middle of the first adjustment bracket 31 and the middle of the second adjustment bracket 32, so that the first adjustment bracket 31 and the second adjustment bracket 32 ​​are rotatably connected. The first adjustment bracket 31 is inclined relative to the horizontal plane, and the first adjustment bracket 31 and the second adjustment bracket 32 ​​are arranged crosswise. The lifting frame 20 has a first sliding groove 21, which is horizontally arranged. The two first sliding grooves 21 are located on opposite sides of the lifting frame 20 and are arranged opposite to each other. One end of an adjusting bracket 31 is slidably received in two first sliding grooves 21 on opposite sides, and the other end of the first adjusting bracket 31 is rotatably connected to the base 10. The base 10 has a second sliding groove 12, which is horizontally arranged. The two second sliding grooves 12 are located on opposite sides of the lifting frame 20 and are arranged opposite each other.

One end of a second adjusting bracket 32 ​​is slidably received in two second sliding grooves 12 on opposite sides, and the other end of the second adjusting bracket 32 ​​is rotatably connected to the lifting frame 20.

[0042] Specifically, the first adjusting bracket 31 is driven to rotate relative to the second adjusting bracket 32. For example, the end of the first adjusting bracket 31 closest to the lifting frame 20 moves closer to the second adjusting bracket 32, increasing the tilt angle of the first adjusting bracket 31. More specifically, the end of the first adjusting bracket 31 closest to the lifting frame 20 moves upward, causing the lifting frame 20 to move upward relative to the base 10 along the sliding cavity 11, thereby adjusting the height of the lifting frame 20. Conversely, when the end of the first adjusting bracket 31 closest to the lifting frame 20 moves away from the second adjusting bracket 32, the lifting frame 20 moves downward relative to the base 10 along the sliding cavity 11, which will not be elaborated further here.

[0043] Moreover, when the first adjusting bracket 31 moves closer to the second adjusting bracket 32, the lifting frame 20 is raised, and the end of the second adjusting bracket 32 ​​near the lifting frame 20 is also raised. The end of the second adjusting bracket 32 ​​near the base 10 slides along the second sliding groove 12 and moves closer to the end of the first adjusting bracket 31 near the base 10.

[0044] In addition, the first adjusting bracket 31 and the second adjusting bracket 32 ​​move closer to or further away from each other to avoid stress concentration at a single point.

[0045] In this embodiment, the first adjusting bracket 31 includes a first adjusting rod 311 and a first connecting rod 312. There are two first adjusting rods 311, which are arranged in parallel and spaced apart.

[0046] The second adjusting bracket 32 ​​includes a second adjusting rod 321 and a second connecting rod 322. There are two second adjusting rods 321, which are arranged in parallel and spaced apart. The two ends of the second connecting rod 322 are respectively connected between the two second adjusting rods 321. The second connecting rod 322 is arranged horizontally, and there are also two second connecting rods 322. The two second connecting rods 322 are parallel to each other and spaced apart. One end of each second adjusting rod 321 is slidably received in a corresponding first sliding groove 21 and rotatably connected to the lifting frame 20, and the other end is slidably received in a second sliding groove 12.

[0047] In one embodiment, a first sliding wheel 50 is installed on the end of the first adjusting bracket 31 near the lifting frame 20. The first sliding wheel 50 is received in the first sliding groove 21 and can slide within the first sliding groove 21. A second sliding wheel (not shown in the figure) is installed on the end of the second adjusting bracket 32 ​​near the base 10. The second sliding wheel is received in the second sliding groove 12 and can slide within the second sliding groove 12.

[0048] Specifically, sliding friction is changed to rolling friction to avoid end wear of the first adjusting rod 311. In this embodiment, two first sliding grooves 21 are provided, and the two first sliding grooves 21 are arranged opposite each other. Specifically, the openings of the two first sliding grooves 21 are arranged opposite each other. A first sliding wheel 50 is installed on the end of the first adjusting rod 311 near the lifting frame 20, and the first sliding wheel 50 can slide along the first sliding groove 21. In addition, a second sliding wheel is also installed on the end of the second adjusting rod near the base 10, and two second sliding grooves 12 are also provided, and the two second sliding grooves 12 are arranged opposite each other.

[0050] Specifically, rotating the handle 34 causes the adjusting screw 35 to rotate accordingly. The screw nut 36 is threadedly connected to the adjusting screw 35, and moves along the length of the adjusting screw 35. One end of the linkage rod 37 connected to the screw nut 36 moves with the screw nut 36, while the other end of the linkage rod 37 drives the first adjusting bracket 31 to move, causing the first adjusting bracket 31 and the second adjusting bracket 32 ​​to move closer or further apart. The adjusting screw 35 is used to improve adjustment accuracy and precisely adjust the height of the lifting platform and electronic scale 40. Both ends of the adjusting screw 35 are rotatably mounted on the lifting frame 20 via bearings.

[0051] In one embodiment, the weighing platform 100 further includes a mounting plate 60, which is mounted on one end of the first adjusting bracket 31 near the base 10.

Part of the base 10 is received in the locking groove 63 so that the mounting plate 60 locks onto the base 10. The first adjusting bracket 31 is hinged to the base body 61 so that the first adjusting bracket 31 can rotate relative to the base 10.

[0053] In this embodiment, a mounting plate 60 is also installed on the end of the second adjusting bracket 32 ​​near the lifting frame 20.

[0054] In one embodiment, the base 10 includes a first vertical rod 13, a first horizontal rod 14, and a second horizontal rod 15. There are four first vertical rods 13 arranged in a matrix. The first horizontal rods 14 are horizontally arranged along the length direction of the base 10. There are two first horizontal rods 14, with one first horizontal rod 14 connected between two corresponding first vertical rods 13. A snap-fit ​​groove 63 snaps into one of the first horizontal rods 14. The second horizontal rods 15 are horizontally arranged along the width direction of the base 10. There are two second horizontal rods 15, with one second horizontal rod 15 connected between two corresponding first vertical rods 13. The second horizontal rod 15 has a second sliding groove 12. Each first vertical rod 13 has a sliding cavity 11.

[0055] The lifting frame 20 includes a second vertical rod 23, a third horizontal rod 24, a fourth horizontal rod 25, and a cover plate 26. There are four second vertical rods 23, one end of which is connected to the four corners of the cover plate 26. The other end of any second vertical rod 23 is slidably connected to a corresponding first vertical rod 13. The third horizontal rod 24 is horizontally arranged along the length of the lifting frame 20. There are two third horizontal rods 24, one of which is connected between two corresponding second vertical rods 23. The fourth horizontal rod 25 is horizontally arranged along the width of the lifting frame 20. There are two fourth horizontal rods 25, one of which is connected between two corresponding second vertical rods 23. The fourth horizontal rod 25 has a first sliding groove 21. The electronic scale 40 is located on the side of the cover plate 26 facing the base 10.

[0056] Specifically, one end of each of the four first vertical rods 13 is placed on the ground, and the other ends of the four first vertical rods 13 extend vertically upwards. Any second vertical rod 23 is slidably connected to a corresponding first vertical rod 13, and the four second vertical rods 23 support the four corners of the cover plate 26 respectively. The purpose of this arrangement is that the second vertical rods 23 support the cover plate 26, ensuring that the cover plate 26 is set horizontally, and further ensuring the stable installation of the electronic scale 40 on the cover plate 26, so as to make the reading more accurate.

[0057] Each of the first vertical bars 13 has a corresponding sliding cavity 11, and the fourth horizontal bar 25 has a first sliding groove 21, so as to make the layout more flexible and the structure more ingenious.

[0058] In this embodiment, the first adjusting rod 311, the second vertical rod 23, the first vertical rod 13, and the second horizontal rod 15 form a triangular stabilizing structure to improve the overall stability of the weighing platform 100. Correspondingly, the second adjusting rod 321, the first vertical rod 13, the second vertical rod 23, and the second horizontal rod 15 also form a triangular stabilizing structure. In this embodiment, the first adjusting bracket 31, the second adjusting bracket 32, the lifting frame 20, and the base 10 form multiple triangular stabilizing structures, which can improve the overall stability of the weighing platform 100.
