Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a conveying structure for a floor-mounted cotton harvester. Background Technology

[0002] The collection and conveying of fallen cotton is a crucial step in cotton recycling, and the performance of its core component, the "toothed collection roller," directly determines the recycling efficiency. Existing fallen cotton harvesters suffer from the following significant technical shortcomings in their conveying structures:

[0003] Fixed teeth are unavoidable and easily entangle debris: Traditional pickup rollers typically have rigidly fixed teeth (welded or bolted), lacking any avoidance function. When encountering tough debris such as plastic film or straw, the debris easily gets tangled between the teeth and the roller body, causing the pickup roller to jam and requiring manual cleaning, severely impacting continuous operation; The radial position is not adjustable, resulting in poor adaptability: The length of the teeth extending beyond the roller body is fixed, only suitable for single-height piles of cotton (such as cotton laid flat with uniform thickness). If the pile height of cotton is uneven (local bulges or depressions), the bulges are prone to breakage due to excessive pressure from the teeth, while the depressions are missed because the teeth cannot reach them. Utility Model Content

[0004] The purpose of this invention is to provide a conveying structure for a ground-mounted cotton harvester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying structure for a ground-mounted cotton harvester, comprising a harvester frame, a pickup roller rotatably connected inside the harvester frame, a plurality of outer sliding rods slidably connected inside the pickup roller, a connecting ring fixedly connected to one end of each outer sliding rod, a first spring fixedly connected between the connecting ring and the inner wall of the pickup roller, the first spring being sleeved on the outside of the outer sliding rod, a second spring fixedly connected inside the outer sliding rod, an inner sliding rod fixedly connected to the other end of the second spring, one end of the inner sliding rod slidably connected inside the outer sliding rod, and a toothed spike fixedly connected to the other end of the inner sliding rod, a tapered rod slidably connected inside the pickup roller, a connecting rod fixedly connected to one end of the tapered rod, a connecting plate fixedly connected to the connecting rod through the pickup roller, a threaded rod threadedly connected to one end of the connecting plate, the tail of the threaded rod rotatably connected to the pickup roller, and a guide rod slidably connected to the other end of the connecting plate, one end of the guide rod being fixedly connected to the pickup roller.

[0006] Preferably, the tapered rod is fixedly connected to support plates at both ends, and the support plates are in close contact with the inner wall of the pickup roller.

[0007] Preferably, connecting plates are fixedly connected to both sides of one end of the outer sliding rod, and a rolling wheel is rotatably connected between the connecting plates. A positioning groove for the rolling wheel is opened on the outer side of the tapered rod, and the rolling wheel is rotatably connected inside the positioning groove.

[0008] Preferably, one end of the inner sliding rod is fixedly connected to an inner positioning rod, and the inner positioning rod is sleeved inside the second spring.

[0009] Preferably, a protective cover is fixedly connected to one end of the harvester frame. The protective cover is sleeved on the outside of the threaded rod and the guide rod. An operating hole is opened at one end of the protective cover, and a slot is opened at the nut of the threaded rod.

[0010] Preferably, the harvester frame has connecting holes on one side and at the bottom, a mounting frame is fixedly connected to one side of the harvester frame, a motor is fixedly connected to one side of the mounting frame, and the power end of the motor is fixedly connected to one end of the pickup roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adjusts the position of the tapered rod by using a threaded rod to flexibly change the extension length of the nail teeth, adapting to cotton at different heights. The protruding part shortens the extension length to avoid cotton breakage, while the recessed part extends the length to prevent missed picking, taking into account the recycling needs of cotton at different stacking states and improving the integrity of picking.

[0013] 2. This utility model also utilizes an inner sliding rod structure driven by a second spring, which allows the nail teeth to automatically retract when they encounter mulch or straw, and quickly reset after debris passes through, eliminating the need for manual cleaning and stopping the machine. This fundamentally solves the problem of "entanglement and jamming" in traditional structures and ensures a continuous and stable conveying process. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a conveying structure for a ground-mounted cotton harvester, including a harvester frame 1. Inside the harvester frame 1, a pickup roller 3 is rotatably connected via a deep groove ball bearing. Several sets of outer sliding rods 4 are circumferentially and evenly slidably connected to the pickup roller 3. One end of each outer sliding rod 4 is fixedly connected to a connecting ring 23 by welding. A first spring 24 is fixedly connected to the inner wall of the pickup roller 3 by spot welding. Under normal conditions, pulling the outer sliding rod 4 inwards causes the first spring 24 to be sleeved on the outside of the outer sliding rod 4 to prevent it from shifting. Inside the outer sliding rod 4, a second spring 19 is fixedly connected by spot welding. The other end of the second spring 19 is fixedly connected to an inner sliding rod 5 by spot welding. One end of the moving rod 5 is slidably connected to the inside of the outer sliding rod 4, and the other end of the inner sliding rod 5 is fixedly connected to the nail tooth 6 by welding. A tapered rod 7 is slidably connected coaxially inside the pickup roller 3. One end of the tapered rod 7 is fixedly connected to the connecting rod 8 by welding. After the connecting rod 8 penetrates the end cover of the pickup roller 3, it is fixedly connected to the connecting plate 9 by bolts. One end of the connecting plate 9 is threadedly connected to the threaded rod 10. The tail of the threaded rod 10 is rotatably connected to the end cover of the pickup roller 3 by a thrust ball bearing. Rotating the threaded rod 10 can drive the connecting plate 9 to move axially. The other end of the connecting plate 9 is slidably connected to the guide rod 11. One end of the guide rod 11 is fixedly connected to the end cover of the pickup roller 3 by welding, which provides guidance for the sliding of the connecting plate 9 and prevents rotation.

[0021] The tapered rod 7 is fixedly connected to the two ends by welding with support plates 15. The support plates 15 are close to the inner wall of the pickup roller 3 to prevent the tapered rod 7 from shifting.

[0022] The outer sliding rod 4 has connecting pieces 16 fixedly connected to both sides by welding at one end. The two connecting pieces 16 are rotatably connected to the roller 17 through a deep groove ball bearing. The outer side of the tapered rod 7 has a positioning groove 18 that matches the roller 17 along the axial direction. The roller 17 is rotatably connected to the inside of the positioning groove 18 to ensure that the outer sliding rod 4 moves smoothly without jamming when it moves with the tapered rod 7. When the tapered rod 7 moves axially, the tapered surface pushes the roller 17 to move radially, thereby driving the outer sliding rod 4 and the nail tooth 6 to extend and retract.

[0023] One end of the inner sliding rod 5 is fixedly connected to an inner positioning rod 20 by welding. The inner positioning rod 20 is sleeved inside the second spring 19 to limit the radial displacement of the second spring 19 and ensure that the second spring 19 only extends and contracts axially.

[0024] One end of the harvester frame 1 is fixedly connected to a protective cover 12 by bolts. The protective cover 12 is fitted on the outside of the threaded rod 10 and the guide rod 11 to prevent cotton wool and dust from covering them. One end of the protective cover 12 has an operating hole 13. The nut of the threaded rod 10 has a slot 14. The threaded rod 10 can be rotated by passing a flathead screwdriver through the operating hole 13 without disassembling the protective cover 12, making it easy to operate.

[0025] The harvester frame 1 has connecting holes 2 on one side and at the bottom. Fallen cotton enters the equipment through the lower connecting hole 2. After being conveyed by the picking roller 3, it enters the subsequent sorting equipment through the connecting hole 2 on one side. A mounting frame 21 is fixedly connected to one side of the harvester frame 1 by bolts. A motor 22 is fixedly connected to one side of the mounting frame 21 by flange bolts. The power end of the motor 22 is fixedly connected to one end of the picking roller 3 through a flexible coupling, driving the picking roller 3 to rotate and realize the picking of fallen cotton.

[0026] Working principle: When using this utility model: Prepare a flathead screwdriver according to the stack height of the fallen cotton; pass the flathead screwdriver through the control hole 13 of the protective cover 12 and insert it into the slot 14 of the threaded rod 10; rotate the screwdriver clockwise or counterclockwise to drive the threaded rod 10 to rotate; the threaded rod 10 is threadedly connected to the connecting plate 9, and the guide rod 11 restricts the rotation of the connecting plate 9, so the connecting plate 9 drives the connecting rod 8 and the tapered rod 7 to move into the pickup roller 3; the conical surface of the tapered rod 7 pushes the rolling wheel 17 to move radially outward along the positioning groove 18, driving the outer sliding rod 4 to compress the first spring 24, and the extension length of the nail tooth 6 increases; rotate the threaded rod 10 in the opposite direction, the tapered rod 7 moves outward of the pickup roller 3, the first spring 24 resets and pushes the outer sliding rod 4 to move radially inward, and the extension length of the nail tooth 6 shortens; after adjusting the extension length of the nail tooth 6 to match the actual height of the fallen cotton, stop rotating the threaded rod 10, the threaded rod 10 self-locks and fixes the position of the tapered rod 7, and the extension length of the nail tooth 6 is locked;

[0027] The motor 22 is connected to the power supply, and the motor 22 drives the picking roller 3 to rotate. The spike teeth 6 of the picking roller 3 contact the fallen cotton and bring the fallen cotton from the connecting hole 2 of the harvester frame 1 into the conveying channel to complete the picking. The first spring 24 ensures that the spike teeth 6 always fits the fallen cotton and adapts to slight height fluctuations. The second spring 19 provides a buffer for the spike teeth 6 to avoid excessive compression of the cotton and breakage. When the spike teeth 6 encounter tough debris such as mulch film and straw, the resistance of the debris to the spike teeth 6 is greater than the elastic force of the second spring 19. The inner sliding rod 5 slides inward along the blind hole of the outer sliding rod 4, compressing the second spring 19. The spike teeth 6 retract into the roller body to avoid the debris from getting tangled. After the debris passes, the second spring 19 elastically resets and pushes the inner sliding rod 5 and the spike teeth 6 outward to restore the normal picking state without stopping the machine for intervention.
