Description

Technical Field

[0001] This utility model relates to the field of sunflower head collection technology, and in particular to a sunflower head collection nozzle. This utility model also relates to a collection device equipped with the aforementioned sunflower head collection nozzle. Background Technology

[0002] Sunflowers are an economic crop; sunflower seeds can be used for food, oil extraction, and animal feed, while sunflower heads can also serve as a high-quality feed ingredient. Currently, during sunflower harvesting, sunflower heads are manually cut off and inserted into the original sunflower stalks to dry quickly, facilitating the subsequent threshing process. However, while the sunflower seeds are dry enough for threshing, the sunflower heads, due to their high moisture content, are not yet dry enough for harvest. Therefore, after threshing, the sunflower heads still need to be scattered in the field to continue drying. However, because the threshed sunflower heads are separated from their original stalks, they fall directly to the ground, mixing with the bent upper halves of previously cut sunflower stalks and the upright lower halves, creating a complex and messy situation. Furthermore, the uneven surface of the sunflower field makes it difficult for existing harvesting machinery to effectively collect the dried heads, often requiring manual collection, which is inefficient.

[0003] To improve the efficiency of sunflower head collection, existing technologies have introduced suction-type collection machines. Most of these machines use a suction tube as the main component. However, previously cut sunflower stalks are often mixed in with the sunflower heads on the ground. These stalks, due to their irregular shape or large size, easily clog the suction tube opening during collection. This clogging not only directly slows down the collection speed and reduces overall harvesting efficiency, but can also cause unnecessary wear and tear on the collection device, even leading to mechanical failures, thus hindering the overall performance of the collection system. Utility Model Content

[0004] In view of this, the present invention aims to provide a sunflower disc collection nozzle to improve the quality of use of the collection device.

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

[0006] A sunflower disc collection tube includes an inner tube, an outer tube disposed on the inner tube and rotatable relative to the inner tube, and a drive mechanism for driving the inner tube and the outer tube to rotate relative to each other.

[0007] The inner tube has a first cutting tooth at its opening, and the outer tube has a second cutting tooth at its opening. When the inner tube and the outer tube rotate relative to each other, the first cutting tooth and the second cutting tooth can cut the sunflower stalks located at the openings of the inner tube and the outer tube.

[0008] Furthermore, there is a sandwich layer between the inner tube and the outer tube, and a lubricating layer is provided in the sandwich layer.

[0009] Furthermore, the lubricating layer includes a lubricating substance filling the interlayer between the inner tube and the outer tube, and the outer tube is provided with a filling port communicating with the interlayer between the inner tube and the outer tube.

[0010] Furthermore, the lubrication layer includes a bearing, the inner ring of which is sleeved on the inner tube, and the outer ring of which is fixed on the outer tube.

[0011] Furthermore, the lubrication layer includes a bushing sleeved on the inner tube and located in the interlayer; when the inner tube and the outer tube rotate relative to each other, the inner wall of the bushing slides against the outer wall of the inner tube, and the outer wall of the bushing abuts against the inner wall of the outer tube.

[0012] Furthermore, it also includes a connecting portion, which includes a first flange extending outward from the end of the inner tube, a second flange extending outward from the end of the outer tube, and a connector; the first flange is located between the second flange and the connector, and the connector is used for assembly onto an external carrier.

[0013] Furthermore, the drive mechanism includes a hydraulic motor and a transmission mechanism that is driven by the hydraulic motor to rotate the inner tube relative to the outer tube.

[0014] Furthermore, the transmission mechanism includes an eccentric wheel and a connecting rod; the eccentric wheel is located on the power output end of the hydraulic motor, and the connecting rod is hinged to the eccentric wheel; the inner tube is provided with a connecting rod extending radially outward along the inner tube, and the other end of the connecting rod is hinged to the connecting rod; the outer tube is provided with a clearance hole corresponding to the movement path of the connecting rod; when the hydraulic motor drives the eccentric wheel to rotate, the connecting rod can slide relative to the outer tube, thereby driving the inner tube to reciprocate relative to the outer tube.

[0015] Furthermore, it also includes a protective cover, which is installed on the drive mechanism to prevent external debris from entering the protective cover.

[0016] Furthermore, the collecting device is provided with a sunflower disc collecting port as described above.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The sunflower disc collecting pipe of this utility model is driven by a driving mechanism to rotate the inner and outer pipes relative to each other, so that the first and second cutting teeth can rotate relative to each other. The first and second cutting teeth can cut the sunflower stalks that are blocked on the pipe opening, thereby preventing the sunflower stalks from clogging the pipe opening, which helps to ensure the absorption effect of the pipe opening and improves the quality of use of the pipe opening.

[0019] Furthermore, the lubrication layer reduces friction between the inner and outer tubes, facilitating their relative rotation and thus extending the equipment's lifespan and performance. Using a lubricating substance as the lubrication layer reduces maintenance costs while ensuring effective lubrication. The filling port on the outer tube facilitates lubrication replenishment, further ensuring lubrication and reducing maintenance difficulty. Similarly, a bearing-like design, with the inner ring of the lubrication layer fitted onto the inner tube and the outer ring fixed to the outer tube, transforms sliding friction into rolling friction, significantly reducing friction between the inner and outer tubes and better enabling their relative rotation. A bushing-like lubrication layer provides excellent lubrication, facilitating relative rotation between the inner and outer tubes, and its simple structure makes it easy to design and implement.

[0020] Furthermore, by incorporating a connecting section including a first flange, a second flange, and a connector, the installation of the pipe opening on the external carrier is facilitated, the connecting section structure is greatly simplified, assembly is easier, and the movement of the inner pipe relative to the outer pipe is restrained, thus reducing costs. Using a hydraulic motor as the drive mechanism not only facilitates assembly but also provides excellent driving performance. The eccentric wheel, connecting rod, and linking rod, driven by the hydraulic motor, allow the inner pipe to rotate relative to the outer pipe, resulting in a simple drive structure, reliable transmission, and ease of design and implementation. The protective cover prevents debris from entering between the inner and outer pipes, protects the drive mechanism from external collisions, ensures transmission reliability, further extends equipment lifespan, reduces maintenance costs, and improves equipment performance.

[0021] Another objective of this invention is to provide a collection device, which includes a sunflower disc collection port as described above.

[0022] The collection device described in this utility model has the same beneficial effects as the sunflower disc collection pipe described above compared to the prior art, so it will not be described again here. Attached Figure Description

[0040] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0042] This embodiment relates to a sunflower disc collection port, which aims to improve the quality of use of the collection device by optimizing the structure of the sunflower disc collection port.

[0043] In terms of overall structure, such as Figures 1 to 7 As shown, the sunflower disc collection port of this embodiment includes an inner tube 10, an outer tube 20 disposed on the inner tube 10 and capable of rotating relative to the inner tube 10, and a drive mechanism for driving the inner tube 10 and the outer tube 20 to rotate relative to each other.

[0044] The inner tube 10 has a first cutting tooth 101 at its opening, and the outer tube 20 has a second cutting tooth 201 at its opening. When the inner tube 10 and the outer tube 20 rotate relative to each other, the first cutting tooth 101 and the second cutting tooth 201 can cut the sunflower stalks located at the openings of the inner tube 10 and the outer tube 20.

[0045] As described above, the sunflower disc collecting pipe of this utility model drives the inner tube 10 and the outer tube 20 to rotate relative to each other through a driving mechanism, so that the first cutter tooth 101 and the second cutter tooth 201 can rotate relative to each other, forming a shearing action. This allows the first cutter tooth 101 and the second cutter tooth 201 to cut the sunflower stalks that are blocking the pipe opening, thereby preventing the sunflower stalks from clogging the pipe opening, helping to ensure the suction effect of the pipe opening, improving the quality of use of the pipe opening, and increasing production efficiency.

[0046] Based on the above overall introduction, in detail, as an exemplary structure, in this embodiment, both the inner tube 10 and the outer tube 20 are cylindrical hollow tubes. The first cutting tooth 101 on the inner tube is triangular, and the second cutting tooth 201 on the outer tube 10 is triangular with rounded edges. Of course, the shapes of the first cutting tooth 101 and the second cutting tooth 201 can also be parallelograms or rectangles, or other shapes in the prior art, as long as they can cut through objects between them when they rotate relative to each other. The first cutting tooth 101 on the inner tube 10 should be longer than the second cutting tooth 201 on the outer tube 20. By using a drive mechanism that drives the inner tube 10 and the outer tube 20 to rotate relative to each other, the first cutting tooth 101 and the second cutting tooth 201 can rotate relative to each other, cutting through the straw that enters the gap between the first cutting tooth 101 and the second cutting tooth 201, thereby cutting the straw blocking the opening into a size that can enter the tube for easy suction.

[0047] In this embodiment, as a preferred implementation, there is an interlayer between the inner tube 10 and the outer tube 20, and a lubricating layer is provided in the interlayer. By providing the lubricating layer, the friction between the inner tube 10 and the outer tube 20 can be reduced, which facilitates the relative rotation of the inner tube 10 and the outer tube 20, thereby helping to improve the service life and performance of the equipment.

[0048] In this embodiment, as a preferred implementation, the lubrication layer includes, for example, a lubricating substance filling the interlayer between the inner tube 10 and the outer tube 20, and the outer tube 20 is provided with a filling port 202 that connects the interlayer between the inner tube 10 and the outer tube 20.

[0049] Using a lubricating substance as the lubrication layer can reduce maintenance costs while ensuring lubrication effectiveness. Furthermore, the addition of a filling port 202 on the outer tube 20 facilitates the replenishment of the lubricating substance, further ensuring lubrication effectiveness and reducing maintenance difficulty. In practical implementation, the lubricating substance can be, for example, lubricating oil or grease, which are well-known to those in the field.

[0050] In addition, the lubricating layer can also be a bearing or a bushing. When the lubricating layer is a bearing, the inner ring of the bearing is fitted onto the inner tube 10, and the outer ring of the bearing is fixed onto the outer tube 20. In this way, the bearing arrangement can transform sliding friction into rolling friction, greatly reducing the friction between the inner tube 10 and the outer tube 20, and better realizing the relative rotation between the inner tube 10 and the outer tube 20. However, using a bearing as a lubricating layer requires sufficient installation space, the structure is relatively bulky, and the bearing is very sensitive to dust, making it inconvenient to add lubricating substances during maintenance.

[0051] When the lubrication layer is a bushing, the inner wall of the bushing slides against the outer wall of the inner tube 10, and the outer wall of the bushing abuts against the inner wall of the outer tube 20. The bushing allows for better relative rotation between the inner tube 10 and the outer tube 20. However, although the bushing provides good lubrication, it is costly and requires higher assembly precision, which is not conducive to the processing and manufacturing of the equipment.

[0052] Therefore, the above two structures were not used in this embodiment, and a lubricating substance was preferably used as the lubricating layer.

[0053] In this embodiment, as a preferred implementation, such as Figure 4 As shown, the sunflower disc collection tube in this embodiment also includes a connecting part 30. The connecting part 30 includes a first flange 301 extending outward from the end of the inner tube 10, a second flange 302 extending outward from the end of the outer tube 20, and a connector 303.

[0054] When the connecting part 30 is assembled on the external carrier, the second flange 302 is assembled on the external carrier through the connector 303. The assembly and fixing method can be, for example, bolt connection, and the first flange 301 is located between the second flange 302 and the connector 303. In this embodiment, the external carrier can be, for example, a wind suction collection machine, and the connecting part 30 is connected to the collection suction pipe of the wind suction collection machine.

[0055] As described above, by providing the connecting part 30, which includes a first flange 301, a second flange 302, and a connector 303, it not only facilitates the installation of the pipe opening on the external carrier but also greatly simplifies the structure of the connecting part 30, making assembly easier. Simultaneously, it ensures that the inner pipe 10 and the outer pipe 20 do not move relative to each other, and helps reduce costs. Furthermore, the second flange 302 may also be provided with a recess 203, so that when the pipe opening is assembled on the external carrier, the first flange 301 is located within the recess 203. Preferably, the recess 203 is also provided with a sliding bushing 304 to facilitate the relative rotation of the inner pipe 10 and the outer pipe 20. In this embodiment, the sliding bushing 304 may be, for example, a sliding pad, a steel ball, or a steel column. It is understood that the recess 203 can also be provided on the connector 303, as long as a space is formed between the second flange 302 and the connector 303 to accommodate the first flange 301.

[0056] In this embodiment, as a preferred implementation, such as Figure 1 and Figure 2 As shown, the drive mechanism includes a hydraulic motor and a transmission mechanism 40 that is driven by the hydraulic motor to drive the inner tube 10 and the outer tube 20 to rotate relative to each other.

[0057] By using hydraulic motors, assembly is not only easier, but the driving effect is also excellent. Furthermore, due to their small size, light weight, and insensitivity to oil contamination, hydraulic motors can reduce labor intensity and improve equipment reliability and lifespan. In addition, hydraulic motors can also be electric motors, which are familiar to those in this field.

[0058] In this embodiment, as a preferred implementation, the transmission mechanism 40 includes an eccentric wheel 401, a connecting rod 402, and a connecting rod 103. The eccentric wheel 401 is located on the power output end of the hydraulic motor. The connecting rod 402 is hinged between the eccentric wheel 401 and the connecting rod 103. The connecting rod 103 extends radially outward along the inner tube 10 and is hinged to the connecting rod 402. An avoidance hole 204 is provided on the outer tube 20 corresponding to the movement path of the connecting rod 103. When the hydraulic motor drives the eccentric wheel 401 to rotate, the connecting rod 103 can slide relative to the outer tube 20, thereby driving the inner tube 10 to reciprocate relative to the outer tube 20.

[0059] With the eccentric wheel 401, connecting rod 402, and connecting rod 103 in place, the inner tube 10 can be driven to rotate relative to the outer tube 20 under the drive of the hydraulic motor. This simplifies the drive structure, ensures reliable transmission, and facilitates design and implementation. Similarly, in practical implementation, the inner tube 10 can be fixed, and the outer tube 20 can be driven to reciprocate relative to the inner tube 10, achieving the same cutting effect.

[0060] In addition, combined Figure 8 As shown, depending on the usage scenario and requirements, the transmission mechanism 40 can also be driven by a gear located at the output end of the hydraulic motor to drive the inner tube 10 to rotate continuously relative to the outer tube 20. However, continuous rotation may cause accelerated wear between the inner tube 10 and the outer tube 20. Alternatively, the transmission mechanism 40 can also be driven by setting a tooth groove on the inner tube 10 and a rack on the connecting rod 402. The rack meshes in the tooth groove. When the eccentric wheel 401 rotates, it drives the rack to slide relative to the inner tube 10, thereby driving the inner tube 10 and the outer tube 20 to reciprocate.

[0061] In this embodiment, as a preferred implementation, a protective cover 50 is also included. The protective cover 50 is installed on the drive mechanism to prevent external debris from entering between the inner tube 10 and the outer tube 20. This facilitates protection of the drive mechanism from external collisions, ensures transmission reliability, extends equipment lifespan, reduces maintenance costs, and improves equipment performance. Furthermore, in specific implementations, due to harsh working environments, the protective cover 50 can also protect the drive mechanism from abrasion by dust or gravel, or from the ingress of liquids, further extending the drive mechanism's lifespan and reducing maintenance costs.

[0062] In this embodiment, the sunflower seed collection pipe opening is driven by a hydraulic motor to move an eccentric wheel 401. This eccentric wheel 402, hinged to the connecting rod 402, drives the connecting rod 103 to reciprocate, thereby causing the inner tube 10 to rotate relative to the outer tube 20. When residual sunflower stalks enter the collection pipe opening, the first cutting tooth 101 on the inner tube 10 opening and the second cutting tooth 201 on the outer tube 20 opening, working in tandem, cut the sunflower stalks, preventing them from clogging the pipe opening.

[0063] The sunflower disc collection pipe in this embodiment is simple, reliable, easy to maintain, and low in manufacturing cost. At the same time, it can ensure the suction effect of the sunflower disc collection pipe, thereby improving the quality of use of the sunflower disc collection pipe, improving harvesting efficiency, and improving the overall quality of use of the machine. Example

[0064] This embodiment relates to a collection device, which includes a sunflower disc collection port as described in Embodiment 1.

[0065] The collection device in this embodiment, by setting the sunflower disc collection pipe opening as in Embodiment 1, helps to ensure the absorption effect of the collection device, thereby improving the quality of use of the collection device, and thus improving the harvesting efficiency and the overall quality of use of the machine.

[0066] 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.
