Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment, and in particular relates to an agricultural packaging bag support frame. Background Technology

[0002] When harvesting crops (such as corn), in order to improve harvesting efficiency and facilitate the transportation of the harvested crops in subsequent work, workers usually carry packaging bags (such as woven bags, burlap sacks or mesh bags) during the harvesting process and collect the harvested crops through the packaging bags.

[0003] As harvesting progresses, the amount of produce inside the bags gradually increases. At this point, the bag opening deforms and shrinks due to the increased quantity of produce, affecting the ease of continued harvesting. Simultaneously, the overall weight of the bag increases with the amount of produce, making it more difficult to move. To address these issues, workers typically employ two people: one to support and restrain the bag opening, while the other harvests the produce, and the two work together to move the bag when necessary. However, this solution not only fails to effectively improve the efficiency and convenience of harvesting but also requires two workers, thus not meeting practical needs. Utility Model Content

[0004] In view of this, the present invention aims to provide an agricultural packaging bag support frame to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An agricultural packaging bag support frame includes a connecting assembly and two constraint units, with the two constraint units arranged mirror images of each other on both sides of the connecting assembly. The connecting assembly includes a first splicing pipe and a second splicing pipe, the first splicing pipe being positioned above the second splicing pipe. A connecting rod is provided on the first splicing pipe, and a connecting tube is provided on the second splicing pipe, with the bottom end of the connecting rod slidably disposed inside the connecting tube. Each constraint unit includes a bottom beam, a support tube, a support rod, and a constraint assembly. A rotatable roller is provided at the end of the bottom beam near the connecting assembly. The support tube is positioned on the top surface of the bottom beam, and the bottom end of the support rod is slidably disposed inside the support tube. A first arc-shaped constraint rod is provided on the side wall of the support rod, with the end of the first arc-shaped constraint rod away from the support rod detachably inserted into the first splicing pipe. A second arc-shaped constraint rod is provided on the side wall of the support tube, with the end of the second arc-shaped constraint rod away from the support tube detachably inserted into the second splicing pipe. The constraint assembly is located at the top of the support rod and includes two adjustable-spaced suspension hooks, with the line connecting the two suspension hooks perpendicular to the support rod.

[0007] Furthermore, the constraint assembly includes a receiving tube and an operating screw. The outer wall of the receiving tube is fixedly connected to the top end of the bearing rod, and the operating screw is rotatably disposed inside the receiving tube. The operating screw includes a first threaded section and a second threaded section with opposite thread directions. Threaded sleeves are provided on both the first and second threaded sections. A mounting seat is provided on the side wall of each threaded sleeve. A guide cut is provided on the side wall of the receiving tube for accommodating the mounting seat, and the two suspension hooks are rotatably connected to the mounting seats on the two threaded sleeves respectively.

[0008] Furthermore, one end of the operating screw is provided with a detachable limiting plate, and the other end of the operating screw is provided with an operating handle, and the outer diameter of the limiting plate is larger than the inner diameter of the receiving tube.

[0009] Furthermore, the connecting tube is provided with a first positioning hole, and a positioning pin is provided inside the first positioning hole; the connecting rod is provided with a plurality of second positioning holes for accommodating the positioning pin, and the plurality of second positioning holes are evenly arranged along the length direction of the connecting rod.

[0010] Furthermore, the first splicing pipe is provided with a first splicing hole, a first splicing pin is provided inside the first splicing hole, and a first receiving hole for accommodating the first splicing pin is provided on the first arc-shaped constraint rod; the second splicing pipe is provided with a second splicing hole, a second splicing pin is provided inside the second splicing hole, and a second receiving hole for accommodating the second splicing pin is provided on the second arc-shaped constraint rod.

[0011] Furthermore, the connecting assembly also includes an operating handle, which is disposed on the first splicing pipe, and the operating handle and the connecting rod are respectively located on both sides of the axis of the first splicing pipe.

[0012] Furthermore, the agricultural packaging bag support frame also includes a reinforcing rod, the two ends of which are detachably connected to the bottom beams of the two constraint units via ground anchors, and the reinforcing rod is located on the side of the bearing tube away from the connecting assembly.

[0013] Compared with existing technologies, the agricultural packaging bag support frame described in this utility model has the following advantages:

[0014] This utility model discloses an agricultural packaging bag support frame that allows two constraint units to be spliced ​​together via a connecting component. Each constraint unit is equipped with two adjustable-spaced hooks. During use, workers can suspend the packaging bag at its opening using these hooks and adjust the spacing between the two hooks within the same constraint component as needed. This allows for flexible control of the bag's opening, preventing deformation and shrinkage when the bag is filled with a large quantity of agricultural products. Furthermore, workers can adjust the spacing between the first and second splicing pipes according to the actual dimensions of the packaging bag, ensuring that the first and second arc-shaped constraint rods provide effective restraint. Additionally, the support frame has rollers at the end of the bottom beam near the connecting component. When moving the packaging bag, workers can tilt the frame towards the connecting component, allowing the first and second arc-shaped constraint rods to support the bag, while the rollers reduce the difficulty of movement, thus facilitating operation. Compared with existing technologies, this support frame enables workers to harvest crops by working alone, thus improving the efficiency and convenience of crop harvesting.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] An agricultural packaging bag support frame, the structure of which can be made of Figures 1-6 The following diagram illustrates the agricultural packaging bag support frame. As shown, in this embodiment, the support frame includes a connecting component and two constraint units, which are arranged mirror images of each other on both sides of the connecting component. During use, the connecting component and the two constraint units can be assembled to constrain and support the packaging bag. After use, the supporting frame can be disassembled for easy storage.

[0029] Specifically, the connecting components include a first splicing pipe 1 and a second splicing pipe 2. The first splicing pipe 1 is positioned above the second splicing pipe 2. A connecting rod 11 is provided on the first splicing pipe 1, and a connecting pipe 21 is provided on the second splicing pipe 2. The bottom end of the connecting rod 11 is slidably disposed inside the connecting pipe 21. Each constraint unit includes a bottom beam 3, a bearing pipe 4, a bearing rod 5, and a constraint assembly. The bearing pipe 4 is positioned on the top surface of the bottom beam 3, and the bottom end of the bearing rod 5 is slidably disposed inside the bearing pipe 4. A first arc-shaped constraint rod 51 is provided on the side wall of the bearing rod 5, and the end of the first arc-shaped constraint rod 51 away from the bearing rod 5 is detachably inserted into the first splicing pipe 1. A second arc-shaped constraint rod 41 is provided on the side wall of the bearing pipe 4, and the end of the second arc-shaped constraint rod 41 away from the bearing pipe 4 is detachably inserted into the second splicing pipe 2.

[0030] When assembling this support frame, workers can first place the two constraint units on both sides of the connecting assembly, and then insert the first arc-shaped constraint rod 51 and the second arc-shaped constraint rod 41 on the two constraint units into the ends of the first splicing pipe 1 and the second splicing pipe 2, respectively. After the assembly is completed, workers can place the packaging bags used to collect crops into this support frame to facilitate subsequent crop harvesting.

[0031] Optional, such as Figure 5 and Figure 6As shown, to improve the splicing reliability between the constraint unit and the connecting component, the first splicing pipe 1 may be provided with a first splicing hole 12, inside which a first splicing pin 121 is provided, and the first arc-shaped constraint rod 51 should be provided with a first receiving hole 511 for accommodating the first splicing pin 121. Correspondingly, the second splicing pipe 2 may be provided with a second splicing hole 22, inside which a second splicing pin 221 is provided, and the second arc-shaped constraint rod 41 should be provided with a second receiving hole 411 for accommodating the second splicing pin 221. Before performing the splicing work, the operator should first remove the first splicing pin 121 and the second splicing pin 221. After completing the splicing, the operator can insert the first splicing pin 121 into the first receiving hole 511 along the first splicing hole 12, and insert the second splicing pin 221 into the second receiving hole 411 along the second splicing hole 22, to prevent the constraint unit from separating from the connecting component.

[0032] Furthermore, since packaging bags of different specifications have different lengths, before use, staff can adjust the distance between the first splicing tube 1 and the second splicing tube 2 according to the length of the packaging bag to meet different usage needs. Correspondingly, to prevent abnormal changes in the distance between the first splicing tube 1 and the second splicing tube 2 during use, the connecting tube 21 can be provided with a first positioning hole 211, and a positioning pin 212 is provided inside the first positioning hole 211. The connecting rod 11 can be provided with multiple second positioning holes 111 for accommodating the positioning pins 212, and the multiple second positioning holes 111 should be evenly distributed along the length direction of the connecting rod 11. After adjusting the distance between the first splicing tube 1 and the second splicing tube 2, staff can insert the positioning pins 212 into the corresponding second positioning holes 111 to lock the distance between the first splicing tube 1 and the second splicing tube 2.

[0033] To facilitate constraint on the opening of the packaging bag, the constraint component in this embodiment is located at the top of the bearing rod 5. For example... Figure 1 As shown, the constraint assembly includes two adjustable-spaced hooks 6, and the line connecting the two hooks 6 is perpendicular to the support rod 5. After the packaging bag is placed inside the support frame, the worker can first suspend the bag opening using the hooks 6, and then adjust the spacing between the two hooks 6 in the same constraint assembly so that the bag opening opens under the action of the hooks 6, ultimately achieving an opening size that meets the needs of harvesting and use. When the bag opening tends to deform due to the filling of crops, the hooks 6 can pull the bag opening to prevent deformation and shrinkage.

[0034] like Figure 4As shown, to achieve the spacing adjustment of the two suspension hooks 6 in the same constraint assembly, the constraint assembly may include a receiving tube 7 and an operating screw 8. Specifically, the outer wall of the receiving tube 7 is fixedly connected to the top end of the bearing rod 5, and the operating screw 8 is rotatably disposed inside the receiving tube 7. The operating screw 8 should include a first threaded section and a second threaded section with opposite thread directions. A threaded sleeve 81 is provided on both the first and second threaded sections, and a mounting seat 82 is provided on the side wall of each threaded sleeve 81. The side wall of the receiving tube 7 should also have a guide cutout 71 for accommodating the mounting seat 82, and the two suspension hooks 6 are rotatably connected to the mounting seats 82 on the two threaded sleeves 81 respectively.

[0035] Because the first and second threaded sections on the operating screw 8 have opposite thread directions, and the fit between the mounting base 82 and the guide notch 71 restricts the rotation of the threaded sleeve 81 inside the receiving tube 7, when the operating screw 8 rotates, the two threaded sleeves 81 move closer or further apart, thereby achieving the purpose of adjusting the distance between the two suspension hooks 6 within the same constraint assembly. Furthermore, since the suspension hook 6 is rotatably connected to the mounting base 82, it can rotate according to the actual stress when pulling the bag opening, thus reducing the risk of the suspension hook 6 damaging the bag.

[0036] Optionally, to prevent the operating screw 8 from separating from the receiving tube 7 and to improve the ease of use of the operating screw 8, one end of the operating screw 8 may be provided with a detachable limiting plate 83 connected by bolts, and the outer diameter of the limiting plate 83 should be larger than the inner diameter of the receiving tube 7. Meanwhile, the other end of the operating screw 8 may be provided with an operating handle 84, so that the operator can input rotational torque to the operating screw 8 via the operating handle 84.

[0037] During actual harvesting, staff need to move the packaging bags periodically. To reduce the difficulty of moving the packaging bags, the support frame should be equipped with rotatable rollers 31 at the end of the bottom beam 3 near the connecting component. When it is necessary to move the packaging bags, the staff can first tilt the support frame towards the direction of the connecting component. At this time, the first arc-shaped constraint rod 51 and the second arc-shaped constraint rod 41 can support the packaging bags, and the rollers 31 can reduce the difficulty of moving the support frame, thus making it convenient for staff to reliably and easily move the packaging bags to the required position.

[0038] Optionally, to further reduce the difficulty of moving this support frame, the connecting assembly may also include an operating handle 13. The operating handle 13 should be installed on the first splicing pipe 1, and the operating handle 13 and the connecting rod 11 should be located on opposite sides of the axis of the first splicing pipe 1. When it is necessary to move this support frame, the operator can grasp the operating handle 13 to facilitate pulling the support frame to move it.

[0039] As an optional implementation of this embodiment, to improve structural strength, the agricultural packaging bag support frame may also include a reinforcing rod 9. During assembly, both ends of the reinforcing rod 9 are detachably connected to the bottom beams 3 of the two constraint units via ground anchors 91, and the reinforcing rod 9 should be located on the side of the bearing tube 4 away from the connecting components. Furthermore, when the support frame is placed on the ground, workers can drive the ground anchors 91 into the ground, thereby further improving the placement stability of the support frame.

[0040] The effects of the above solution are explained below:

[0041] This embodiment provides an agricultural packaging bag support frame, which can adjust the opening of the packaging bag through a hanging hook and prevent the bag opening from deforming during use. Secondly, the support frame can support the packaging bag through a first and second arc-shaped constraint rod, and the rollers reduce the difficulty of moving the packaging bag. Furthermore, the support frame can flexibly adjust the distance between the first and second splicing pipes, thereby providing good support and constraint for packaging bags of different sizes.

[0042] 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.
