Description

Technical Field

[0001] The present application belongs to the technical field of mechanized garlic harvesting, and in particular relates to a garlic soil and film removal device and a harvester. Background Art

[0002] Currently, garlic is mostly grown using mulch. When harvested with a harvester, some of the shredded mulch residue is fed into the harvester along with the garlic bulbs. Furthermore, due to garlic's well-developed root system, a significant amount of soil is mixed into the bulbs and roots when they are unearthed, making them more noticeable in the soil. Furthermore, weeds, rotten leaves, and other debris may also be fed into the harvester. This soil, debris, and mulch residue can become entangled or accumulate in the harvester's rotating components, seriously impacting harvesting efficiency and machine reliability. To improve the quality of garlic, farmers manually screen and sort garlic with significant debris, but this increases processing costs. Therefore, how to remove soil and mulch residue from the garlic during the harvest process has become a major concern for technicians. Summary of the Invention

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present application, many technical details are proposed to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present application. The various embodiments can be combined with each other and referenced to each other under the premise of no contradiction.

[0044] Currently, the existing technology has the problem of how to remove the soil and residual mulch film from garlic during the garlic harvesting process.

[0045] To solve the above problems, Figure 1 As shown, an embodiment of the present application provides a garlic soil and film removal device, which is applied to a garlic harvester. The garlic harvester may have a garlic shoveling device, which is used to shovel garlic out of the soil one by one. The garlic enters the garlic soil and film removal device one by one and is transferred to a root and stem cutting device, and finally enters a collection bucket or a collection vehicle. The garlic soil and film removal device specifically includes a clamping rod transmission component 1 and a cleaning component.

[0046] Among them, the clamping rod transmission assembly 1 is used to clamp the stems of garlic and transport the garlic; because the garlic is removed from the ground and then transported to the collection bucket, the clamping rod transmission assembly 1 is configured with a lower input end and a higher output end. During the transmission process, the garlic is basically in a vertical position, with the stems and leaves facing upward and the heads facing downward. The cleaning assembly is set below the clamping rod transmission assembly 1 and is used to clean the garlic heads during the transmission process; in a specific setting, the cleaning assembly can be directly connected to the clamping rod transmission assembly 1, or it can be connected to the garlic harvester separately from the clamping rod transmission assembly 1, and the two can form an upper and lower relationship in space. During the transmission process of the clamping rod transmission assembly 1, the garlic heads pass through the cleaning assembly to clean the soil and residual film attached to the garlic heads, thereby preventing the soil or residual film from being entangled or accumulated on the rotating parts of the harvester, and eliminating the need for manual removal of debris.

[0047] In one embodiment of the present application, as shown in Figure 2 and Figure 3 the specific structure of the clamping rod transmission assembly 1 includes a support 11 and two transmission belts 12, which can be belt or chain transmission. The support 11 is used to be mounted on the harvester; the two transmission belts 12 are mounted on the support 11, and the transmission surfaces of the two transmission belts 12 are oppositely arranged, that is, the two transmission surfaces of the two transmission belts 12 jointly clamp and transmit the garlic. In addition, the clamping rod transmission assembly 1 further includes a power assembly for driving the rotation of the transmission belt 12, and the two ends of each transmission belt 12 are supported by a rotating shaft, and the transmission surfaces of the two transmission belts 12 are oppositely arranged to clamp and transmit the stems of the garlic; each support 11 is provided with a tensioning mechanism, for example, a plurality of supporting wheels 13 are arranged on the support, which abut against the inner side of the transmission surface of each transmission belt 12 to support the transmission belt 12 and ensure that the distance between the transmission surfaces of the two transmission belts 12 is sufficient to clamp the garlic.

[0048] The cleaning assembly includes:

[0049] Two oppositely arranged fixed frames 20 are respectively fixed below the supports 11, one fixed frame 20 is installed below each support 11, and the two fixed frames 20 have a gap through which the stems and heads of the garlic can pass. In order to ensure that the garlic has sufficient passing space, the fixed frame spacing D of the two fixed frames 20 is usually greater than 10 cm. Two cleaning parts are respectively installed on the two fixed frames 20 for cleaning the heads of the garlic. During the transmission of the garlic, the heads and part of the stems of the garlic pass through the gap between the two fixed frames 20, and the two cleaning parts installed on the two fixed frames 20 clean the dirt or residual film on the garlic.

[0050] Preferably, a part of the two cleaning parts is in contact to form a flexible filling channel through which the garlic can pass, and the impurities attached to the garlic are removed by the flexible filling channel when the garlic passes through the flexible filling channel. The direction of the flexible filling channel has a preset angle θ with the transmission direction of the transmission belt 12, and in this condition, since the stems of the garlic are clamped by the transmission belt 12, the path formed by the head of the garlic passes through the flexible filling channel at the preset angle θ.

[0051] In one embodiment of the present application, as shown in Figure 2 and Figure 4 the cleaning assembly further includes: the cleaning part is a rolling brush 211; the brush rotating shaft 212 is rotatably connected with the fixed frame 20 for mounting and driving the rolling brush 211 to rotate; the driving connecting piece 213 is used to drive the rotation of the brush rotating shaft 212; wherein the driving connecting piece 213 is connected with the external driving, and the driving connecting piece 213 can be a structural member driven by a gear or a belt.

[0052] As shown in Figure 6As shown, the outer periphery of the rolling brush 211 may be cylindrical, with the bristles in the same radial direction; or as shown in FIG. Figure 7 The spiral rolling brush 2111 shown; or the radius at both ends is larger and the radius in the middle is smaller, which is convenient for the passage of the garlic head.

[0053] Furthermore, if Figure 2 As shown, the brush's rotation axis is parallel to the plane formed by the garlic's transport and forms a preset angle θ with the transport direction of the conveyor belt 12. This allows the upper portion of the garlic head to first contact the rolling area of ​​the rolling brush 211 during transport, with the root of the garlic head finally leaving the rolling area, ensuring that the garlic head is cleaned from top to bottom. The preset angle θ is adjustable from 0 to 90°. To ensure that the garlic passes through the passage between the rolling brushes 211 from beginning to end, a smaller angle requires a longer rolling brush 211, and the garlic travels a greater distance within the brush. Due to space constraints, a 20° angle is preferred.

[0054] Preferably, if Figure 5 and Figure 8 As shown, the two rolling brushes 211 rotate in opposite directions: Figure 8 In a, the rotation direction of the two rolling brushes 211 is from the garlic stem to the head, and the brushes on both sides are opposite to the upward movement direction of the garlic. The brushes on both sides pull the dirt or residual film on the garlic head from top to bottom.

[0055] Preferably, if Figure 8 In Figure b, the two rolling brushes 211 rotate in the same direction. Because some residual film is wrapped around the garlic stem and stuck to the head, if the two rolling brushes 211 rotate in opposite directions, the residual film will be pulled to both sides simultaneously, making it less likely to loosen and fall off. Therefore, in this embodiment, the two rolling brushes 211 rotate in the same direction: the rolling brush 211 on one side rotates from bottom to top along the edge of the garlic, loosening and lifting the residual film at the top of the garlic head, while the rolling brush 211 on the other side rotates from top to bottom along the outside of the garlic, pulling the lifted residual film downward from that side to separate it from the garlic.

[0056] In one embodiment of the present application, Figure 9 、 10 As shown in FIG11 , the cleaning assembly further includes two chains 223 and a plurality of sprockets 222 ; at least two sprockets 222 are mounted on each fixing frame 20 , and at least two sprockets 222 support one chain 223 for rotation, and the axial direction of the sprocket 222 is parallel to the plane formed by the garlic transmission; the cleaning portion is a soft-based brush 221 , which is mounted on the rotating periphery of the chain 223 , and the two soft-based brushes 221 rotate with their respective chains 223 to clean the garlic.

[0057] In one embodiment of the present application, the two cleaning parts areFigure 13 The sheet-like flexible plate 231 shown in Figure 12 Similarly, the cleaning portion, whether it is a rolling brush 211, a sheet-like flexible plate 231, or a strip brush 241, can be set at a preset angle θ with the conveyor belt 12.

[0058] In one embodiment of the present application, when the two conveyor belts 12 clamp the garlic stems, the garlic heads are kept at a predetermined distance from the conveyor belts 12. Since the residual membrane of the freshly scooped garlic usually hangs on the upper half of the garlic head and the stem connected to the head, the predetermined distance allows the cleaning assembly to clean these two parts without obstruction.

[0059] Another aspect of the present application provides a harvester, on which is installed the garlic soil and film removal device of any of the above technical solutions, and therefore has all the advantages and beneficial effects of the above garlic soil and film removal devices.
