[0001] This utility model relates to the field of rice-picking mechanism technology, specifically a rice-picking mechanism for a soybean harvester. Background Technology

[0002] The stalk-pulling mechanism of a soybean harvester is one of its key components. It is mainly used to effectively guide the soybean stalks in the field to the cutting mechanism, ensuring that the soybeans can be harvested smoothly.

[0003] In the prior art, a utility model patent with publication number CN215011735U and titled "A Soybean Harvester's Reeling Mechanism" includes a frame, a protective rod, and a connecting rod. The protective rod is fixedly connected to the lower end of the frame, and the connecting rod is fixedly connected to the middle of the rear side of the frame. A movable column is movably connected to one side of the connecting rod, and a connection port is provided on the right side of the movable column. A transmission ring is movably connected to the left rear side of the frame, and a cutter is fixedly connected to the lower end inside the frame. This utility model, by setting up a cutter, a cutting box, a cutting blade, a connector, a slide rail, and a connecting block, allows the cutting box to be connected to the connector within the cutter during actual use. This enables the connecting block within the connector to slide along the slide rail, improving the cutting efficiency and speed of the soybean harvesting process. Furthermore, it protects the cutting blade from rust and damage when the device is not in operation, allowing for faster soybean harvesting and facilitating practical use.

[0004] However, the external cutting box in this patented device may be interfered with by external objects such as crops and stones during operation, which may cause some inconvenience to the staff. Utility Model Content

[0005] The purpose of this invention is to provide a soybean harvester reeling mechanism.

[0006] The technical problem solved by this utility model is that the external cutting box in the existing equipment may be interfered with by external objects such as crops and stones during operation, which will cause some inconvenience to the workers.

[0007] This utility model can be achieved through the following technical solution: a soybean harvester reeling mechanism, including a frame connected to the harvester, the frame including a reeling wheel and a spiral pusher rotatably connected thereto, a horizontal cutter provided at the front end of the frame, a support plate fixedly installed at the front end of the inner side of the frame, a sliding groove for accommodating the horizontal cutter opened in the inner cavity of the support plate, a miniature electric telescopic rod fixedly installed at the middle end of the inner cavity of the support plate, the output end of the miniature electric telescopic rod extending into the inner cavity of the sliding groove and fixedly connected to the horizontal cutter, the built-in design of the miniature electric telescopic rod allows the horizontal cutter to be completely retracted when not in use, thereby reducing its contact with the external environment, reducing wear and corrosion, and thus significantly extending the service life of the cutter and reducing maintenance costs.

[0008] A further technical improvement of this utility model is that: the inner cavity of the sliding groove in the support plate is provided with a coating mechanism for applying anti-rust oil to the horizontal cutting blade. The coating mechanism includes two adsorption sponge plates that are symmetrically and elastically slidably connected to the inner cavity of the sliding groove, and the adsorption sponge plates are provided with anti-rust oil.

[0009] A further technical improvement of this utility model is that the absorbent sponge board fits the shape of the horizontal cutter, which makes it easier to apply rust-removing oil to both sides of the horizontal cutter.

[0010] A further technical improvement of this utility model is that: the support plate is provided with a supply component for providing anti-rust oil to the adsorbent sponge plate. The supply component includes two receiving grooves for receiving anti-rust oil, which are located in the inner cavity of the support plate and on both sides of the miniature electric telescopic rod. A feeding groove communicating with the receiving groove is opened in the inner cavity of the support plate and on one side of the receiving groove. The side of the feeding groove away from the receiving groove is connected to a sliding groove. A plug bead for sealing the connection between the feeding groove and the receiving groove is elastically slidably connected in the inner cavity of the feeding groove.

[0011] A further technical improvement of this utility model is that: two connecting rods are symmetrically fixedly installed on one side of the horizontal cutter and in the inner cavity of the sliding groove. The connecting rods extend into the inner cavity of the feeding groove and are fixedly installed with a push rod that is slidably connected to the inner cavity. The movement of the horizontal cutter drives the push rod to move synchronously, and the continuous movement of the push rod pushes the stop ball to move.

[0012] A further technical improvement of this utility model is that a reserved space is formed between the push rod and the plug ball. The reserved space is designed to prevent the leakage of anti-rust oil when the equipment is storing the horizontal cutter, thereby making the equipment more convenient for workers to use.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. After the harvesting work is completed, the present invention drives the miniature electric telescopic rod. By shortening the miniature electric telescopic rod, the horizontal cutter can be completely inserted into the sliding groove of the inner cavity of the support plate. This makes it easy to completely store the horizontal cutter in the inner cavity of the support plate, avoiding interference from crops, stones and other external objects, thus ensuring the safety of the equipment and making it convenient for workers to use.

[0015] 2. This utility model allows for selective application of rust-preventive oil to the horizontal cutting blade based on its usage. When rust-preventive oil application is required, the micro-electric telescopic rod is driven to shorten again, allowing the horizontal cutting blade to enter between the two adsorption sponge plates. The movement of the horizontal cutting blade drives the connecting rod to move synchronously, which in turn drives the push rod to slide within the inner cavity of the feeding trough. As the push rod slides continuously, it pushes the blocking bead to slide synchronously. The sliding of the blocking bead allows the rust-removing oil in the receiving trough to enter the two adsorption sponge plates through the feeding trough. The contact between the two adsorption sponge plates and the horizontal cutting blade facilitates the application of rust-removing oil. After a measured amount of rust-removing oil is discharged, the micro-electric telescopic rod extends. This extension not only facilitates the repositioning of the blocking bead but also prevents excessive application of rust-removing oil, thus conveniently meeting the needs of the operators.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figure 1-5 As shown, this embodiment provides a technical solution: a soybean harvester reeling mechanism, including a reeling wheel 2 rotatably connected to a frame 1. The frame 1 is connected to the harvester, and the reeling wheel 2 is connected to the frame 1 via a fixed plate. A spiral pusher 3 is rotatably connected to the inner cavity of the frame 1. The spiral pusher 3 is installed on the inner side of the frame 1 near the conveying port. A support plate 4 is fixedly installed at the front end of the inner side of the frame 1, and a horizontal cutter 5 is slidably connected to the front end of the support plate 4.

[0030] The inner cavity of the support plate 4 is provided with a sliding groove 41 for receiving the horizontal cutter 5. A miniature electric telescopic rod 42 is fixedly installed at the middle of the inner cavity of the support plate 4. The output end of the miniature electric telescopic rod 42 extends into the inner cavity of the sliding groove 41 and is fixedly connected to the horizontal cutter 5.

[0031] The inner cavity of the support plate 4 is equipped with a coating mechanism for applying rust-preventive oil to the horizontal cutting blade 5. The coating mechanism includes two connecting springs 414 symmetrically fixed to the inner cavity of the sliding groove 41 of the support plate 4. On the side of the connecting springs 414 away from the inner wall of the sliding groove 41, there is a receiving frame plate 412 that is slidably connected to the inner cavity of the sliding rod 45. The inner cavity of the receiving frame plate 412 is equipped with an absorbent sponge plate 413, which fits the shape of the horizontal cutting blade 5. Two rust-preventive oil containers are symmetrically arranged on both sides of the micro electric telescopic rod 42 within the inner cavity of the support plate 4. The receiving groove 43 has an injection port for injecting rust-preventive oil into the receiving groove 43 on the side of the support plate 4 away from the horizontal cutter 5. The inner cavity of the injection port is provided with a sealing plug 411 to block it. The inner cavity of the support plate 4 and on one side of the receiving groove 43 is provided with a feeding groove 44 that communicates with the receiving groove 43. The side of the feeding groove 44 away from the receiving groove 43 is connected to the sliding groove 41. The inner cavity of the feeding groove 44 is slidably connected with a sliding rod 45. A plug bead 46 for blocking the connection between the feeding groove 44 and the receiving groove 43 is fixedly installed at the middle end of one side of the sliding rod 45.

[0032] Two sliders 47 are fixedly installed at both ends of the sliding rod 45. The inner cavity of the support plate 4 is provided with a moving groove 48 for the sliders 47 to slide. A support spring is fixedly installed on the inner wall of the moving groove 48. The side of the support spring away from the inner wall of the moving groove 48 is fixedly connected to the slider 47.

[0033] Two connecting rods 49 are symmetrically fixedly installed on one side of the horizontal cutter 5 and in the inner cavity of the sliding groove 41. The connecting rods 49 extend into the inner cavity of the feeding groove 44 and are fixedly installed with a push rod 410 that is slidably connected to the inner cavity. When the horizontal cutter 5 is in use, a reserved space is formed between the push rod 410 and the sliding rod 45. The reserved space makes it easy to store the horizontal cutter 5 in the inner cavity of the sliding groove 41. When the horizontal cutter 5 needs to be coated with anti-rust oil, the push rod 410 is slid by the miniature electric telescopic rod 42, thereby shortening the reserved space until the push rod 410 can push the sliding rod 45 to slide. The sliding of the sliding rod 45 allows the anti-rust oil in the receiving groove 43 to flow into the adsorption sponge plate 413 through the feeding groove 44.

[0034] When the horizontal cutter 5 is needed, the present invention drives the micro electric telescopic rod 42. The extension of the micro electric telescopic rod 42 causes the horizontal cutter 5 to slide in the sliding groove 41 in the inner cavity of the support plate 4 until the horizontal cutter 5 is fully exposed. After the horizontal cutter 5 is exposed, the harvesting work can be carried out.

[0035] After the harvesting is completed, the mini electric telescopic rod 42 is driven again. The shortening of the mini electric telescopic rod 42 allows the horizontal cutter 5 to fully enter the sliding groove 41 inside the support plate 4, thus making it easy to completely store the horizontal cutter 5 inside the support plate 4 and avoid interference from crops, stones and other external objects.

[0036] Workers can selectively apply rust-preventive oil to the horizontal cutter 5 according to its usage. When rust-preventive oil needs to be applied, the micro electric telescopic rod 42 is driven to shorten it again, allowing the horizontal cutter 5 to enter between the two adsorption sponge plates 413. When the horizontal cutter 5 moves, it drives the connecting rod 49 to move synchronously. The connecting rod 49 drives the push rod 410 to slide in the inner cavity of the feeding groove 44. As the push rod 410 slides continuously, it pushes the plug bead 46 to slide synchronously. The sliding of the plug bead 46 allows the rust-removing oil in the receiving groove 43 to enter the two adsorption sponge plates 413 through the feeding groove 44. The contact between the two adsorption sponge plates 413 and the horizontal cutter 5 facilitates the application of rust-removing oil. After the measured amount of rust-removing oil is discharged, the micro electric telescopic rod 42 is extended. The extension of the micro electric telescopic rod 42 not only facilitates the reset of the plug bead 46 but also avoids excessive application of rust-removing oil.

[0037] No action is required if it does not need to be coated with rust-preventive oil.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
