Abstract
Description
Technical Field
[0001] This utility model relates to the field of crop harvesting technology, and in particular to a drum screen device for mud. Background Technology
[0002] Taro cultivation should prioritize sandy loam or clay loam soils, as these soils offer both good aeration and effective water retention.
[0003] However, when taro is dug up, it usually comes with a lot of soil attached. Transporting it directly would take up more space, and the heavy soil would increase the difficulty of transportation and reduce efficiency. But, it would be very time-consuming and labor-intensive to have someone specifically remove the soil from the taro.
[0004] Therefore, it is very meaningful to develop a drum screen device for removing soil from root crops such as taro, which is time-consuming and laborious to remove the attached soil during harvesting. Utility Model Content

[0012] A toothed ring is formed on the outer surface of the roller, and the roller drive assembly includes a motor and a gear set connected to the output shaft of the motor. The output gear of the gear set can mesh with the toothed ring.
[0013] Optionally, a groove is provided on the side of the limiting arc near the roller, and an annular ridge is formed on the outer surface of the roller. The annular ridge can be inserted into the groove, and when the roller rotates, the annular ridge slides in the groove.
[0014] Optionally, a protruding ridge is formed on the side of the limiting arc near the roller, and an annular groove is formed on the outer surface of the roller. The protruding ridge can be inserted into the annular groove, and when the roller rotates, the protruding ridge slides in the annular groove.
[0015] Optionally, a plurality of limiting arcs are provided at intervals on the mounting rod.
[0016] Optionally, the frame has a waist-shaped hole, and the mounting base is installed on the waist-shaped hole of the frame by fasteners.

[0033] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.
[0034] like Figures 1 to 4 As shown, this utility model provides a drum mud screening device 60, which includes a frame 10, a drum 61 rotatably mounted on the frame 10 and capable of rotating on the frame 10, and a drum drive assembly 62 for driving the drum 61 to rotate. The drum 61 has multiple mud-leaking holes 611 (densely distributed in multiple rows and columns, with the total area of all mud-leaking holes 611 exceeding half the area of the outer surface of the drum 61 to facilitate the discharge of mud), and spiral blades 612 are provided on the inner surface of the drum 61. The rotating drum 61 can screen mud on the rhizomes when conveying them, and the spiral blades 612 can enhance the removal effect of mud on the rhizomes.
[0035] In this invention, taking taro as an example of a root crop, the aforementioned drum mud-screening device is equipped with spiral blades 612 and mud-leaking holes 611, which can remove the mud attached to the taro while it is being transported. Furthermore, the drum 61 exerts virtually no pressure or impact on the taro, resulting in good safety during transport and minimizing losses and waste, thus providing a high degree of protection for the taro. This drum mud-screening device boasts a series of advantages, including high applicability, low cost, simple operation, time and labor saving, and high safety and reliability, effectively meeting the needs of taro harvesting and possessing significant market development potential.
[0036] See you again Figures 1 to 4 The frame 10 is provided with a pair of limiting brackets 63. Each limiting bracket 63 includes a pair of mounting seats 631, a mounting rod 632 mounted between the pair of mounting seats 631, and a limiting arc 633 set on the mounting rod 632. The limiting arcs 633 on the pair of limiting brackets 63 are arranged relative to the rollers 61. The curvature of the limiting arcs 633 is adapted to the curvature of the rollers 61 to radially limit the rollers 61. That is, the pair of limiting arcs 633 clamp the rollers 61 but do not affect the rotation of the rollers 61, and the rollers 61 can rotate between the relative limiting arcs 633. The mounting seats 631 can be installed on the frame 10 by fasteners (screws or bolts, etc.). The frame 10 has a slotted hole at the corresponding position. When the fastener is loosened, the mounting seats 631 can move along the transverse direction of the frame 10. Figure 3 The roller 61 is displaced a certain distance (corresponding to the limiting distance of the oblong hole) in the left-right direction to facilitate its installation and removal. For example, when the roller 61 needs to be disassembled, the fasteners are loosened, and the paired mounting seats 631 are moved away from each other to remove the roller 61. When the roller 61 needs to be installed, the roller 61 is first placed in the predetermined position, then the mounting seats 631 are moved so that the paired limiting arcs 633 clamp the roller 61, and finally the fasteners are tightened to complete the installation of the roller 61. In addition, in Figures 1 to 4 A pair of limiting arcs 633 are correspondingly provided on the middle roller 61. In a preferred embodiment, multiple limiting arcs 633 can also be provided at intervals on the mounting rod 632, thereby forming multiple pairs of limiting arcs 633 distributed at intervals along the axial direction of the roller 61 to improve the reliability of the roller 61 installation.
[0037] Furthermore, a gear ring 613 is formed on the outer surface of the roller 61. The roller drive assembly 62 includes a motor 621 and a gear set 622 connected to the output shaft of the motor 621. The output gear of the gear set 622 can mesh with the gear ring 613. The axle of the output gear is rotatably mounted on a mounting base 631, and the mounting rod 632 is parallel to the axle of the output gear. To ensure the stability of the roller 61 during rotation, see [reference needed]. Figure 2 The roller drive assembly 62 also includes a rotatable auxiliary gear 623 that can mesh with the gear ring 613. The mounting rod 632 is parallel to the axle of the auxiliary gear 623, and the roller 61 is located between the auxiliary gear 623 and the output gear. The auxiliary gear 623 and the output gear support the rotating roller 61 from both sides of the roller 61.
[0038] In a preferred embodiment, such as Figure 1 and Figure 2As shown, a groove is formed on the side of the limiting arc 633 near the roller 61, and an annular ridge 614 is formed on the outer surface of the roller 61. The annular ridge 614 can be inserted into the groove to form axial limiting. When the roller 61 rotates, the annular ridge 614 slides in the groove. The cooperation between the annular ridge 614 and the groove can provide circumferential guidance while performing axial limiting, which is a very ingenious structure. Alternatively, a protruding ridge is formed on the side of the limiting arc 633 near the roller 61, and an annular groove is formed on the outer surface of the roller 61. The protruding ridge can be inserted into the annular groove to form axial limiting. When the roller 61 rotates, the protruding ridge slides in the annular groove.
[0039] Also, see again Figure 4 The diameter of the roller 61 gradually decreases from the inlet end to the outlet end, which allows the taro to gradually gather and collect during the mud screening and conveying process until it enters the collection frame. The dug taro is put into the roller 61 from the inlet end. As the roller 61 rotates, the mud attached to the taro falls off through the mud leakage hole 611, and the taro gradually moves towards the outlet end and finally rolls from the outlet end into the collection frame.
