[0001] The utility model relates to the technical field of medicinal material harvesting, in particular to a combined screen structure of a medicinal material harvester. Background Art

[0002] With the improvement of agricultural mechanization level, some crops have achieved mechanized harvesting. However, due to the particularity of medicinal materials, traditional agricultural machinery is often not suitable for the harvesting of medicinal materials. At the same time, the harvesting of medicinal materials not only requires taking the medicinal materials out of the soil, but also requires screening and separation to remove impurities and weeds to ensure the quality of the medicinal materials. Therefore, screening and separation technology plays a key role in the process of medicinal material harvesting.

[0003] In the existing medicinal material harvesting process, the screening and cleaning of medicinal materials are crucial links. The traditional method of screening and cleaning medicinal materials mainly relies on manual labor, which is not only inefficient, but also labor-intensive and easily affected by human factors, resulting in unstable screening quality. Therefore, a combined screen structure of a medicinal material harvester is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 The utility model provides an embodiment: a combined screen structure of a medicinal material harvester, including a bracket 1, a fixed plate 23 is fixedly connected inside the bracket 1, a servo motor 6 is fixedly connected to the top of the fixed plate 23, a turntable 7 is fixedly connected to the output end of the servo motor 6, a connecting rod 8 is rotatably connected to the outside of the turntable 7, one end of the connecting rod 8 is rotatably connected to a fixed column 9, both ends of the fixed column 9 are fixedly connected to a slider 11, the outside of the fixed column 9 is fixedly connected to a support rod 12, the bottom of the support rod 12 is fixedly connected to a screen mechanism 4, one side of the screen mechanism 4 is fixedly connected to a slider 2 13, and a disassembly component is installed on the outside of the bracket 1.

[0031] Specifically, the servo motor 6 drives the rotation of the turntable 7, thereby driving the connecting rod 8 and the screen mechanism 4 to swing, so as to achieve the separation and screening of medicinal materials. The turntable 7 starts to swing through the rotation, thereby driving the movement of the fixed column 9 and the support rod 12. The fixed column 9 is fixed at one end of the connecting rod 8, so that the fixed column 9 drives the slider 11 and the support rod 12 to move left and right. The slider 11 is fixed at both ends of the fixed column 9, and the slider 2 13 is fixed on one side of the screen mechanism 4. They may play the role of supporting and stabilizing the connecting parts, making the movement smoother.

[0032] Reference Figure 2 , Figure 3 The disassembly assembly includes a vertical plate 15, the outside of the vertical plate 15 is slidably connected to one side of the bracket 1, one side of the vertical plate 15 is fixedly connected to a spring 18, the other side of the vertical plate 15 is fixedly connected to a connecting column 17, the inside of the bracket 1 is slidably connected to a pull rod 19, the outside of the pull rod 19 is sleeved with a spring 21, one end of the spring 21 is fixedly connected to a baffle 22, one side of the baffle 22 is fixedly connected to a fixed plate 23, one side of the bracket 1 is fixedly connected to a connecting plate 2, the inside of the connecting plate 2 is slidably connected to a scraper 3, and one side of the scraper 3 is provided with a groove 24.

[0033] Specifically, spring 18 is fixed on the vertical plate 15, and is compressed when the vertical plate 15 moves to the right, providing a certain reaction force to help the vertical plate 15 remain in the moved position, so that the connecting column 17 is disengaged from the inside of the limiting hole 20, and the handle 16 is pulled by external force to move the pull rod 19, thereby driving the movement of the baffle 22, and at the same time compressing the tension of spring 21, so that the other end of the pull rod 19 is disengaged from the groove 24, so that the scraper 3 can be disassembled or replaced.

[0034] Reference Figure 2 A groove 10 is provided on the upper inner side of the bracket 1, and the outer part of the slider 11 is slidably connected to the inner part of the groove 10. A limiting groove 14 is provided on the lower inner side of the bracket 1, and the outer part of the slider 13 is slidably connected to the inner part of the limiting groove 14. Universal wheels 5 are arranged around the bottom of the bracket 1.

[0035] Specifically, through the design of groove 10, the slider 11 drives the fixed column 9 to move more stably, and through the restriction of the limit groove 14, the slider 2 13 drives the screen mechanism 4 to move left and right, and through the installation of the universal wheel 5, the screen mechanism 4 moves smoothly.

[0036] Reference Figure 3 and Figure 4One end of the pull rod 19 extends to the outside of the bracket 1 and is fixedly connected to the handle 16, the other end of the pull rod 19 is slidably connected to the inside of the groove 24, a limiting hole 20 is opened on the outside of the pull rod 19, the outside of the connecting column 17 is slidably connected to the inside of the limiting hole 20, and the other end of the spring 18 is fixedly connected to the inside of the bracket 1.

[0037] Specifically, by pulling the handle 16 , the other end of the pull rod 19 is disengaged from the interior of the second groove 24 , and by inserting the connecting column 17 , the position of the pull rod 19 is limited, and by the tension of the spring 18 , the movement of the vertical plate 15 is controlled.

[0038] Working principle: First, when the device is working, the shovel 3 collects the medicinal materials on the ground, and when the medicinal materials are mixed with soil and move toward the screen mechanism 4 through the connecting plate 2, when the medicinal materials enter the inside of the screen mechanism 4, the motor servo motor 6 is started to make the turntable 7 start to rotate, and the rotation of the turntable 7 makes the connecting rod 8 start to swing, and at the same time, the fixed column 9 rotatably connected to one end of the connecting rod 8 starts to move, but under the connection of the slider 11, the fixed column 9 moves more stably, and at the same time, the support rod 12 outside the fixed column 9 starts to move left and right, and driven by the support rod 12, the screen mechanism 4 starts to swing, and driven by the slider 2 13, the screen mechanism 4 swings at a uniform speed;

[0039] Secondly, when the blade 3 needs to be disassembled and replaced, the vertical plate 15 is moved to the right so that the spring 18 is in a compressed state, thereby causing the connecting column 17 to disengage from the interior of the limiting hole 20. At the same time, the handle 16 is pulled by external force to move the pull rod 19, thereby driving the baffle 22 to move inside the bracket 1. When the baffle 22 moves, the spring 21 is compressed, thereby causing the other end of the pull rod 19 to disengage from the interior of the groove 24, thereby facilitating the staff to disassemble and inspect the blade 3.
