Description

Technical Field

[0001] This utility model belongs to the field of beet pulling machine screen plate mechanism, specifically a beet gathering double screen plate structure. Background Technology

[0002] The beet puller is an agricultural machine specifically designed for harvesting beet root crops. Its main function is to efficiently pull beets out of the soil and perform preliminary cleaning. The sieve tray collecting mechanism is a commonly used mechanism in the puller, mainly responsible for soil separation, root and stem collection, and preliminary impurity removal. Existing puller collecting mechanisms generally use a single sieve tray, which is prone to accumulation and has a relatively low effect on removing soil and other impurities from beets. Therefore, we designed a double sieve tray structure for beet collecting with better soil screening and impurity removal effect. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A double-sieve tray structure for gathering beets, such as Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, the device includes a sieve plate mechanism. The sieve plate mechanism is installed on the frame 1 of the beet pulling machine. The beet pulling machine is a mature existing technology and will not be described in detail here. The sieve plate mechanism includes a flat frame 7, which is installed on the frame 1. A rotating sieve plate 4 is rotatably installed on the flat frame 7. A drive mechanism for driving the rotating sieve plate 4 to rotate is installed on the flat frame 7. There are two rotating sieve plates 4, one on the left and one on the right. Several arc-shaped spring scales 5 are fixedly installed on the rotating sieve plate 4. The spring scales 5 are evenly distributed around the circumference. The two rotating sieve plates 4 are staggered, with one rotating sieve plate 4 being higher and the other rotating sieve plate 4 being lower. This utility model has a simple structure and ingenious design. The double rotating sieve disc 4 and the spring ruler 5 on it can make most of the soil and impurities on the sugar beets fall off, resulting in good soil and impurity removal. The double sieve disc mechanism provides a more stable pushing force when conveying sugar beets, making it easier to gather the sugar beets from the outer circle to the center, which is more efficient and easier for the subsequent sugar beet picking cart to pick them up. The two sieve disc mechanisms are staggered vertically, which saves space compared to those of the same height. When they rotate, the overlapping parts can clean the impurities stuck on the spring ruler 5, which can meet practical needs and is suitable for promotion. In use, the beet harvester harvests beets and they eventually enter the sieve mechanism. The drive mechanism rotates the two sieve discs 4, causing the spring scales 5 on them to rotate as well. This causes the beets to gather from both sides towards the center and finally fall to the ground from one point. As the sieve discs 4 and spring scales 5 transport the beets, they shake off dirt and other impurities from the beets, which then fall through the gaps between the spring scales 5. When debris gets stuck on the spring scale 5 of one sieve disc 4, the spring scale 5 rotates the debris to the middle of the two sieve discs. There is an overlap between the spring scales 5 on both sides in the vertical direction, and the spring scale 5 on the other sieve disc 4 can exert a force on the debris, pulling it off, thus achieving the effect of cleaning the sieve mechanism.

[0017] Specifically, as shown in the figure, the rotating screen 4 in this embodiment is provided with a guide plate 20 on one side. The guide plate 20 is fixedly installed on the flat frame 7 and is located above the spring scale 5. One end of the connecting rod is fixedly connected to one side of the guide plate 20, and the other end of the connecting rod is fixedly connected to the frame 1. The guide plate 20 can provide guidance for the beets on the spring scale 5, making it easier for the beets to gather and be transported to the center, facilitating the subsequent centralized collection and processing of the beets.

[0018] Specifically, as shown in the figure, the flat frame 7 described in this embodiment is installed on the frame 1 through several lifting mechanisms. The lifting mechanism includes a lifting rod 30, one end of which is hinged to the flat frame 7, and the other end of which is fixedly installed with a screw 31. A square tube 32 is slidably mounted on the lifting rod 30. The lifting rod 30 has a square cross-section. The square tube 32 is fixedly installed on the frame 1. A U-shaped plate 33 is fixedly installed on the square tube 32. A through hole is opened on the U-shaped plate 33, through which the screw 31 passes. Hexagonal nuts 34 are respectively provided on both sides of the U-shaped plate 33. The hexagonal nuts 34 are threadedly installed on the screw 31. When the height of the flat frame 7 needs to be adjusted, turn the two hexagonal nuts 34 on the screw 31 to loosen them from clamping the U-shaped plate 33. To bring the flat frame 7 closer to the ground, turn the two hexagonal nuts 34 upwards. To move it further from the ground, turn the two hexagonal nuts 34 downwards. After adjustment, turn the upper hexagonal nut 34 until the two hexagonal nuts 34 clamp the U-shaped plate 33. The adjustment of the flat frame 7 is then complete. When the flat frame 7 is raised or lowered, it will move the rotating screen 4 together, thereby adjusting the height of the rotating screen 4 from the ground to adapt to different ground conditions.

[0019] Further, as shown in the figure, the driving mechanism described in this embodiment includes a rotating shaft 40. The rotating shaft 40 is fixedly installed on the rotating screen 4. The rotating shaft 40 is rotatably connected to the sleeve 41 through bearings. The sleeve 41 is fixedly installed on the flat frame 7. The rotating shaft 40 is fixedly connected to the output shaft of the reducer 42. The reducer 42 is fixedly installed on the flat frame 7. The output shaft of the reducer 42 is coaxially arranged with the corresponding rotating shaft 40, rotating screen 4, and sleeve 41. The input shaft of the reducer 42 is fixedly installed with sprockets 43. The flat frame 7 is fixedly installed with a gearbox 44. An external power source, such as a drive motor or hydraulic motor, provides driving force to the gearbox 44. The output shaft of the gearbox 44 is also fixedly installed with sprockets 43. The corresponding sprockets 43 are connected by chain drive. The chain is not shown in the figure. The gearbox 44 is driven by an external power source. The gearbox 44 transmits power to two reducers 42 through the chain and sprocket 43. After the two reducers reduce the speed, they drive the two rotating shafts 40 to rotate, thereby driving the rotating screen 4 to rotate, and then driving the spring scale 5 on the rotating screen 4 to revolve.

[0020] Furthermore, as shown in the figure, in this embodiment, a dustproof ring 50 is fixedly installed on the rotating sieve plate 4, and a dustproof cover 52 is fixedly installed on the sleeve 41. The inner ring of the dustproof cover 42 is fixedly connected to the outer circumference of the sleeve 41, and the upper end of the dustproof ring 50 extends into the dustproof cover 52. The dustproof cover 52 and the dustproof ring 50 can prevent dirt and other impurities on the beets from affecting the bearing between the sleeve 41 and the rotating shaft 40, ensuring the normal use of the bearing.

[0021] Furthermore, as shown in the figure, in this embodiment, several baffles 6 are provided on one side of the rotating screen 4. The baffles 6 are fixedly installed on the flat frame 7, and the corresponding baffles 6 are detachably installed on the same retaining ring 8 by bolts and nuts. The retaining ring 8 is also detachably installed on the flat frame 7 by bolts and nuts. The baffles 6 can prevent the beets conveyed to the spring scale 5 from falling off the opposite sides of the two rotating screens 4.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
