[0002] A beet leaf trimmer is an agricultural machine that uses mechanical striking and cutting technology to efficiently separate the leaves and tubers of beets during harvest, preserving the intact tubers for sugar production or further processing. However, when the leaf trimmer trims the leaves of beets, the trimmed leaves are flung off, posing a certain safety hazard. Therefore, we have designed an adjustable baffle for the beet leaf trimmer to provide protection. 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] An adjustable baffle for a beet leaf trimming vehicle, such as Figure 1 , 2As shown in Figures 1 and 3, the machine includes a frame 1, on which a gearbox 2 is fixedly mounted. The output shaft of the gearbox 2 is connected to a main shaft 3 via chain drive. In this embodiment, the gearbox 2 has one input shaft and two output shafts. The gearbox 2 transmits power to the main shaft 3, which is rotatably mounted on the frame 1 via bearings. Several blasting blades 11 are mounted on the main shaft 3. The gearbox 2 transmits power to the main shaft 3, which drives the blasting blades 11 to blast the beets. A connecting frame for connection to a tractor is fixedly mounted on one side of the frame 1. The connecting frame includes several connecting components... The frame 1 is fixedly connected to a tensioning column and a connecting plate with connecting holes for connection to a tractor. A movable wheel 15 is installed on the other side of the frame 1. An arc-shaped protective plate 4 is fixedly installed on the frame 1. A baffle 5 is hinged to the protective plate 4 via a hinge 10. Tie rods 6 are hinged to both sides of the baffle 5. Several evenly distributed limiting holes 7 are formed on the tie rods 6. Vertical rods 8 corresponding to the tie rods 6 are fixedly installed on the frame 1. Through slots 12 through which the tie rods 6 pass are formed on the vertical rods 8. Insertion holes 9 that align with the limiting holes 7 are formed on the side walls of the through slots 12. This utility model has a simple structure and ingenious design. The baffle 5 can block the blades 11 that are flung away, preventing injury to the operator. The baffle 5 can also be angled according to the slope of the field to ensure effective blade blocking. Adjusting the angle of the baffle 5 can also reduce the impact of the blades on the baffle 5, meeting practical needs and suitable for widespread application. In use, rotate the baffle 5 along the hinge 10 according to the required angle. When rotating, the tie rod 6 slides in the through groove 12 on the vertical rod 8 and rotates along its corresponding hinge axis. After the angle of the baffle 5 is adjusted, insert the bolt into the limiting hole 7 and the corresponding insertion hole 9, and tighten the nut. At this time, the baffle 5 can no longer rotate and the angle is fixed. The blades thrown out by the blade 11, as well as soil, can be blocked by the baffle 5.

[0017] Specifically, as shown in the figure, a pair of support legs 14 are fixedly installed on one side of the frame 1 in this embodiment. When the frame 1 is not connected to the tractor, the support legs 14 support one side of the frame 1 to prevent it from contacting the ground, so as to keep it level and facilitate use.

[0018] Specifically, as shown in the figure, the hinge 10 in this embodiment includes a shaft cup leaf 30 and a shaft rod leaf 31. The shaft rod leaf 31 can be inserted into the shaft cup leaf 30. A plug is fixedly provided on the shaft rod leaf 31, and a plug cylinder is fixedly provided on the shaft cup leaf 30. During installation, the shaft cup leaf 30 is installed onto the protective plate 4 using bolts and nuts, and the shaft rod leaf 31 is installed onto the baffle 5. Then, the shaft rod leaf 30 is inserted into the shaft cup leaf 10 to complete the installation of the baffle 5. When the baffle 5 needs to be removed, the shaft rod leaf 30 can be pulled out of the shaft cup leaf 10, which realizes the quick disassembly of the baffle 5 and increases its practicality.

[0019] Furthermore, as shown in the figure, the frame 1 described in this embodiment is equipped with a topping cutter 43. This device moves in the field; the leaf-removing 11 first passes over the sugar beet to remove the leaves, and then the topping cutter 43 passes over the sugar beet again to remove the remaining stems, leaves, and root tissue at the top of the sugar beet, achieving complete separation of leaves and roots, facilitating subsequent processing, and increasing practicality.

[0020] Furthermore, as shown in the figure, several first mounting plates 40 are fixedly installed on the other side of the frame 1 in this embodiment. One end of several connecting rods 41 is hinged to the first mounting plate 40, and the other end of the corresponding connecting rods 41 is hinged to the same second mounting plate 42. The corresponding first mounting plate 40, connecting rods 41, and second mounting plate 42 form a parallelogram mechanism, and the topping blade 43 is installed on the second mounting plate 42. The first mounting plate 40, connecting rods 41, and second mounting plate 42 form a parallelogram mechanism. When the topping blade 43 contacts the sugar beet, it will encounter resistance, thereby causing the parallelogram mechanism to rotate along the hinge axis. This allows the topping blade 43 to automatically adjust the topping position according to the height of the sugar beet plant, avoiding excessive topping and waste.

[0021] Furthermore, as shown in the figure, in this embodiment, a sleeve 60 is fixedly installed on the second mounting plate 42. An mounting rod 63 is fitted inside the sleeve 60. The cutting blade 43 is fixedly connected to the mounting rod 63. Several through holes are opened on the sleeve 60, and threaded nuts are fixedly installed thereon. A limiting bolt 62 is installed in conjunction with the internal thread of the threaded nut. One end of the limiting bolt 62 abuts against the mounting rod 63. The mounting rod 63 can move within the sleeve 60, thereby adjusting the distance between the cutting blade 43 and the ground. The cutting blade 43 can be adjusted according to the height of the beet. After adjustment, the limiting bolt 62 is tightened so that one end of the limiting bolt 62 is close to the mounting rod 63, thereby restricting the movement of the mounting rod 63.

[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.
