DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0033] Please refer to Figures 1-8 A kind of impurity removal assembly of seed melon combined harvester, is assembled in the installation rack 11 of harvester and is matched with the seedling cutting assembly 12 of harvester.

[0034] Including installation support 2 and active shaft 31, driven shaft 32 rotationally installed at both ends of installation support 2 and kept parallel arrangement, installation support 2 is fixedly installed in installation rack 11, and the both ends of active shaft 31, driven shaft 32 are respectively fixedly connected with active sprocket 33, driven sprocket 34, and active sprocket 33 and driven sprocket 34 are realized chain transmission by assembly chain 35.

[0035] The scraper assembly 4 is mounted on the assembly chain 35 and is uniformly distributed, and the scraper assembly 4 comprises a mounting beam 41, a scraper plate 42 and a spring tooth 43. The mounting beam 41 is fixedly connected to the two assembly chains 35. The scraper plate 42 is fixedly mounted on the mounting beam 41 and is perpendicular to the extension direction of the assembly chain 35. The inner side end of the scraper plate 42 is attached to the upper surface of the mounting bracket 2. The outer side end of the scraper plate 42 is provided with a plurality of spring teeth 43 which are uniformly distributed along the length direction of the scraper plate 42.

[0036] The seed melon harvester is driven by an agricultural tractor or other vehicles to move and operate in the field. When the toothed drum 13 provided at the front side of the harvester operates, the seed melon can be clamped on the teeth and transported together with the melon stem along with the toothed drum 13. Then the seed melon is captured by the long-toothed drum 14 provided at the rear side and transported rearward along with the long-toothed drum 14. During the transportation, the seed melon is captured by the rear collecting assembly 15 and broken to obtain seeds, while the melon stem continues to be transported along with the long-toothed drum 14 to the stem cutting assembly 12 provided above. After being cut by the stem cutting assembly 12, the melon stem is transported to the impurity removing assembly and finally output from one side of the mounting frame 11 together with the mesh and other impurities.

[0037] When the impurity removing assembly operates, the driving shaft 31 drives the driving sprocket 33 to rotate. Under the cooperation of the driven shaft 32 and the driven sprocket 34, the two assembly chains 35 are stably driven to operate. The assembly chains 35 can drive the scraper assemblies 4 uniformly mounted thereon to operate synchronously. The inner side end of the scraper plate 42 can push the impurities falling on the mounting bracket 2 to be stably transported and discharged to one side of the mounting frame 11.

The driving sprocket 33, the driven sprocket 34, the assembly chain 35 and the scraper assembly 4 are arranged inside the two side plates 22.

[0040] The bottom plate 21 and the side plates 22 can effectively support the transported melon stem and impurities and prevent them from falling off from the two sides of the mounting bracket 2, thereby improving the effective transportation and discharge of the impurity removing assembly. The driving sprocket 33, the driven sprocket 34, the assembly chain 35 and the scraper assembly 4 are arranged inside the two side plates 22, which can ensure the stable installation of the scraper assembly 4 and effectively transport the melon stem and impurities inside the side plates 22.

[0041] Ball bearings are also assembled at both ends of the mounting bracket 2 to ensure that the driving shaft 31 and the driven shaft 32 can be stably mounted in a relative rotating manner at both ends of the mounting bracket 2.

[0048] The turnover shaft 61 is also rotatably installed in the mounting rack 11 and arranged above the material guide plate 5, and the turnover plate 62 is fixedly assembled on the turnover shaft 61. The outer end of the turnover plate 62 is in contact with the upper surface of the material guide plate 5, and the driving shaft 31 is in transmission connection with the turnover shaft 61.

[0049] One end of the material guide plate 5 is fixedly connected with one group of side plates 22 to ensure that the melon vines transferred by the material guide plate 5 can be effectively transferred to the bottom plate 21 between the two groups of side plates 22. The two ends of the turnover shaft 61 are assembled on the mounting rack 11 through the matched ball bearings to stably install the turnover shaft 61.

[0050] The two groups of turnover plates 62 arranged in the same diameter direction are arranged on the turnover shaft 61. When the turnover shaft 61 operates, the turnover plates 62 on it stably operate, and the turnover plates 62 can stably transfer the cut melon vines on the material guide plate 5 to the bottom plate 21 of the mounting bracket 2.

[0051] The fixed clamping plate 611 is arranged along the length direction on the turnover shaft 61.

The transmission shaft is connected with the output shaft of the agricultural tractor. Specifically, the power of the transmission shaft can be first transmitted to the cutting assembly 12 to drive the cutting assembly 12 to operate. The cutting assembly 12 is provided with a sprocket which is chain-transmitted with the driving sprocket A 613. When the cutting assembly 12 is driven to operate by the external power source, the turnover shaft 61 and the driving shaft 31 in the impurity removal assembly can be stably operated synchronously.

[0056] Since the axes of the driving shaft 31 and the turnover shaft 61 are vertically distributed, two groups of bevel gears which are vertically distributed and meshed can be assembled in the reversing gear box 311.
