Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery equipment technology, specifically, it relates to a rotomolded seed box for agricultural machinery. Background Technology

[0002] Seed boxes are mainly used in agricultural sowing and are usually fixed to agricultural machinery for convenient seed storage during cultivation. Currently, seed boxes on the market are typically made of either metal or plastic. Sheet metal seed boxes are heavy, have weak resistance to sudden impacts, are difficult to repair, have high maintenance costs, and are prone to rust. Furthermore, seed boxes operate in complex and variable environments and are subject to high-frequency vibrations. Therefore, the application of metal seed boxes in agriculture, especially on agricultural machinery, has certain limitations.

[0003] To overcome the drawbacks of metal seed boxes, rotational molding is currently used to manufacture plastic seed boxes in one piece. This effectively meets functional requirements while also achieving lightweight design. However, in windy weather, because rotational molded seed boxes are lightweight, the lid can be blown off and reclosed by strong winds when workers open the lid to add seeds, affecting the process. Alternatively, strong winds can cause the lid to collide with the box body, damaging the seed box. Therefore, plastic seed boxes still have certain limitations compared to metal seed boxes. Utility Model Content

[0004] To address the technical problems of easily being blown off and replaced by strong winds and damaged by impacts due to the light weight of rotomolded planting boxes, this utility model provides a rotomolded seed box for agricultural machinery.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rotomolded seed box for agricultural machinery includes a box body and a box lid. First hinge blocks are symmetrically arranged at one end of the upper surface of the box body. A connecting rod is arranged between the two first hinge blocks. Second hinge blocks are symmetrically arranged at the other end of the upper surface of the box body. The second hinge blocks have through-grooves extending through both sides. The box lid has first slots corresponding to the positions of the two second hinge blocks. A first through-hole is formed at one end of the box lid corresponding to the second hinge blocks. A first shaft is inserted into the first through-hole. A second slot is formed at one end of the box lid corresponding to the positions of the two first hinge blocks. A second through-hole is formed at one end of the box lid corresponding to the first hinge blocks. A second shaft is inserted into the second through-hole. Each of the second hinge blocks has a protrusion. A first anti-rotation rib is connected to the box lid near the protrusion. A boss is provided on the box body corresponding to the position between the two second hinge blocks. A second anti-rotation rib is connected to the box lid near the boss.

[0007] Furthermore, a rotatable hook is provided on the second shaft corresponding to the position of the two second slots; a handle is provided in both second slots, and the handle and the hook are prefabricated as an integral unit.

[0008] Furthermore, both the first and second shafts have annular grooves in their middle sections; a first open retaining ring and a second open retaining ring are respectively engaged in the two annular grooves; the cover is provided with limiting blocks at the positions corresponding to the middle sections of the first and second shafts; the limiting blocks are provided with third slots at the positions corresponding to the first and second open retaining rings; the limiting blocks are provided with semi-circular grooves at the positions corresponding to the first or second shafts, allowing the first or second shaft to pass through.

[0009] Furthermore, the upper surface of the box body is provided with a box opening; a matching protruding edge is provided at the edge of the box opening; and a sealing strip is also snapped onto the box lid at the position corresponding to the protruding edge.

[0010] Furthermore, when the lid is opened, it rotates due to the force applied by the hand until the second anti-rotation rib on the lid comes into contact with the boss, at which point the lid can no longer rotate counterclockwise. At this point, the force applied by the hand to the lid is removed, and the lid exerts a force on the first shaft under its own weight, causing the first shaft to move downward in the groove. At this time, the first anti-rotation rib also moves downward, so that the first anti-rotation rib comes into contact with the boss, and the lid cannot rotate clockwise.

[0011] Furthermore, by grasping the handle and lifting the lid upwards, the first anti-rotation rib moves upwards, disengaging from the contact between the first anti-rotation rib and the protrusion, thereby allowing the lid to rotate clockwise.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, when the operator adds seeds to the rotomolded seed box, the lid and the box body are rotatably connected by the first shaft. When the lid is opened, it will rotate due to the force applied by the hand until the second anti-rotation rib on the lid abuts against the protrusion, preventing the lid from rotating counterclockwise. At this point, the force applied by the hand to the lid is removed, and the lid exerts a force on the first shaft under its own weight, causing the first shaft to move downward in the groove. At this time, the first anti-rotation rib also moves downward, so that the first anti-rotation rib abuts against the protrusion, preventing the lid from rotating clockwise. This achieves the purpose of fixing the lid and preventing the lid from rotating counterclockwise or clockwise under strong winds. It will not affect the operator adding seeds to the box, nor will it cause the lid to be damaged by impact with the box body under strong winds.

[0014] 2. When the operator needs to seal the box, they can grasp the handle and lift it upwards, causing the first anti-rotation rib to move upwards and disengage from the abutment between the first anti-rotation rib and the protrusion. This allows the box cover to rotate clockwise until the lower surface of the box cover is completely in contact with the protrusion, thus sealing the box. Afterwards, the handle is turned so that the one-piece hook on it is connected to the connecting rod, improving the sealing effect between the box cover and the box. It is simple and convenient to use and has good stability. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 3 as well as Figures 10-11 As shown, a rotationally molded seed box for agricultural machinery includes a box body 1 and a box cover 2 connected to each other, with the box cover 2 located on the upper part of the box body 1. The box body 1 is made of LLDPE material using a rotational molding process (LLDPE material is odorless, non-toxic, oil-resistant, resistant to most acid and alkali corrosion, has good plasticity, good chemical stability, and low density, which enables the seed box to be lightweight and has a high plastic deformation recovery ability even under long-term bumps or vibrations). The rotational molding process is used to make the wall thickness of the box body 1 at the corners and apex, which are prone to stress, 5mm-8mm. The average value of mm makes the load-bearing surface of the box 1 slightly thicker, which makes the structure safer. The upper surface of the box 1 is provided with a box opening 9; the edge of the box opening 9 is provided with a matching convex edge 10; the upper surface of the box 1 is symmetrically provided with a first hinge block 11 corresponding to one end of the convex edge 10; a connecting rod 12 is provided between the two first hinge blocks 11, and the two ends of the connecting rod 12 are fixedly connected to the two hinge blocks by bolts; the upper surface of the box 1 is symmetrically provided with a second hinge block 14 corresponding to the other end of the convex edge 10; the second hinge block 14 is provided with a waist groove 13 that runs through both sides.

[0030] The cover 2 has a matching first slot 16 at the position of the two second hinge blocks 14, and the outer side of the first slot 16 is open; the cover 2 has a through first round hole 17 at one end corresponding to the second hinge block 14, and the first round hole 17 is connected to the two first slots 16; a first shaft 4 is inserted into the first round hole 17.

[0031] The lid 2 has a second slot 19 corresponding to the position of the two first hinge blocks 11, and the outer side of the second slot 19 is open; the lid 2 has a through second round hole 18 at one end corresponding to the first hinge block 11, and the second round hole 18 communicates with the two second slots 19; a second shaft 6 is inserted into the second round hole 18; a rotatable hook 8 is provided on the second shaft 6 corresponding to the position of the two second slots 19, and the hook 8 is used to connect with the connecting rod 12; a handle 22 is provided in both second slots 19, and the handle 22 and the hook 8 are prefabricated as an integral part.

[0032] Both the first shaft 4 and the second shaft 6 have annular grooves 27 in their middle sections; a first open retaining ring 5 and a second open retaining ring 7 are respectively engaged in the two annular grooves 27, and the annular grooves 27 are used to restrict the axial movement of the first open retaining ring 5 and the second open retaining ring 7 on the first shaft 4 and the second shaft 6 respectively; the cover 2 is provided with limiting blocks 24 at the middle positions of the first shaft 4 and the second shaft 6; the limiting blocks 24 are provided with third slots 25 at the positions of the first open retaining ring 5 and the second open retaining ring 7, and the third slots 25 are used to restrict the axial movement of the first open retaining ring 5 and the second open retaining ring 7; the limiting blocks 24 are provided with semi-circular grooves 26 at the positions of the first shaft 4 or the second shaft 6, for the first shaft 4 or the second shaft 6 to pass through.

[0033] A sealing strip 3 is also attached to the lid 2 at the position corresponding to the protruding edge 10. The sealing strip 3 works in conjunction with the protruding edge 10 to improve the airtightness of the connection between the box body 1 and the lid 2.

[0034] Please see Figure 2 and Figures 4-9 As shown, each of the second hinge blocks 14 is provided with a protrusion 20; the cover 2 is connected to the first anti-rotation rib 21 near the protrusion 20; the box body 1 is provided with a boss 15 corresponding to the position between the two second hinge blocks 14; the cover 2 is connected to the second anti-rotation rib 23 near the boss 15.

[0035] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0036] The operator first removes the second open retaining ring 7 from the middle of the second shaft 6, then aligns the integrated prefabricated handle 22 and hook 8 with the two second slots 19, and then inserts the second shaft 6 through the second round hole 18 to connect the box cover 2 and the integrated prefabricated handle 22 and hook 8. Next, the second open retaining ring 7 is aligned with the annular groove 27 in the middle of the second shaft 6 and inserted into the annular groove 27. Then, the second open retaining ring 7 is used in conjunction with the third slot 25 to fix the second shaft 6 and the box cover 2. Next, the operator aligns the two first slots 16 on the box cover 2 with the two second hinge blocks 14, then removes the first open retaining ring 5 in the middle of the first shaft 4, inserts the first shaft 4 through the first round hole 17, connects the first hinge block 11 and the box cover 2, then aligns the first open retaining ring 5 with the annular groove 27 in the middle of the first shaft 4 and inserts it into the annular groove 27, and then uses the first open retaining ring 5 in conjunction with the third slot 25 to fix the first shaft 4 and the box cover 2, thereby completing the connection between the box cover 2 and the box body 1.

[0037] When the operator adds seeds into the rotomolded seed box, because the lid 2 and the box body 1 are rotatably connected via the first shaft 4, the lid 2 will rotate when opened due to the force applied by the hand, until the second anti-rotation rib 23 on the lid 2 abuts against the boss 15 (e.g., Figure 9 As shown), the lid 2 can no longer rotate counterclockwise. At this point, the force applied to the lid 2 by hand is released, and the lid 2, under its own weight, exerts a force on the first shaft 4, causing the first shaft 4 to move downwards within the waist groove 13. Simultaneously, the first anti-rotation rib 21 moves downwards, causing the first anti-rotation rib 21 to abut against the protrusion 20 (as shown). Figure 5 As shown, the lid 2 cannot rotate clockwise, thus achieving the purpose of fixing the lid 2 and preventing the lid 2 from rotating counterclockwise or clockwise under strong winds. This will not affect the workers adding seeds into the box 1, nor will it cause the lid 2 to be damaged by impacting the box 1 under strong winds.

[0038] When the operator needs to seal the housing 1, they grasp the handle 22 and lift it upwards, causing the first anti-rotation rib 21 to move upwards, thus disengaging the first anti-rotation rib 21 from its contact with the protrusion 20 (as shown). Figure 7 As shown, the lid 2 can be rotated clockwise until the lower surface of the lid 2 is completely in contact with the protruding edge 10, thus sealing the box body 1. Then, the handle 22 is rotated so that the one-piece hook 8 on it is hooked with the connecting rod 12, which improves the sealing effect between the lid 2 and the box body 1. It is simple and convenient to use and has good stability.
