Description

Technical Field

[0001] This invention belongs to the field of soil cultivation technology, and in particular to a spiral-type tobacco curing and soil cultivation device. Background Technology

[0002] Spiral-type tobacco cultivation and hilling device is a key agricultural machine in tobacco planting. It is mainly used in the middle stage of tobacco growth. The surface soil of the field furrows is prone to forming a compacted layer due to rainfall, irrigation or mechanical operation, which hinders root respiration and nutrient absorption. The spiral device effectively breaks up the compacted layer through rotating blades or spiral structure, increases soil porosity, improves aeration, and promotes root development.

[0003] In existing publicly available literature, patent publication number CN221178341U discloses a device for cultivating and ridging tobacco. This prior art uses four blades located at different radial positions on the same plane of a rotating shaft, with a winch installed at the outer end of the shaft and its inner end close to the rotary tiller disc. The winch is a spiral disc. This device integrates digging, conveying, and loosening of the soil, improving the mechanization rate of ridging operations and the timeliness of agricultural operations. However, this technology still has the following problems.

[0004] When cultivating and hilling tobacco, the spiral hilling device relies on the contact between the spiral blades and the soil in the furrows to achieve the purpose of loosening the soil. However, in actual operation, there are a lot of grasses in the furrows. These grasses are very easy to get tangled in the various spiral gaps of the spiral blades. Once tangling occurs, the maintenance work in the spiral gaps in the later stages faces great difficulties. Not only is it time-consuming and laborious to deal with, but the existing maintenance methods are also difficult to automatically peel off the grasses tangled in the gaps of the spiral blades from multiple angles, which makes the self-maintenance efficiency of the hilling device low. Summary of the Invention

[0005] Purpose of the invention: To provide a spiral-type tobacco cultivation and hilling device, which improves the self-maintenance efficiency of the hilling device by setting a multi-functional maintenance module that can cut and remove the grass in the spiral gap. Technical solution

[0006] A spiral-type tobacco cultivation and hilling device includes a hilling component housed in a machine frame, and a multi-dimensional maintenance module for cleaning the hilling component.

A cutting groove is formed on the spiral component along the radial direction of the spiral component. The multi-dimensional protection module includes a power component and a first cleaning mechanism that is slidably connected to the shaft cylinder. The power component is located outside the shaft cylinder and is used to drive the first cleaning mechanism to extend from the shaft cylinder into the cutting groove to cut the grass in the gap of the spiral component.

The second cleaning mechanism and the third cleaning mechanism work together with the first cleaning mechanism to push the grass away from the shaft.

[0007] In some possible embodiments, the first cleaning mechanism includes a grooving cutter, the length of which matches the length of the auger. The oblique groove cutter is slidably connected to the slide plate, and the slide plate is fixed inside the shaft cylinder.

[0008] In a further embodiment, one end of the grooving cutter is connected to the power assembly via a slide rod; The power assembly includes an electric cylinder and a connecting bar installed at the output end of the electric cylinder. The end of the slide rod that is not connected to the inclined cutter passes through the slide groove and is connected to the connecting bar. The groove is formed on the shaft cylinder, and the slide rod slides back and forth in the groove along the radial direction of the shaft cylinder.

[0009] In a further embodiment, the second cleaning mechanism is provided with several sets, and the second cleaning mechanism includes a first linkage component and a first separation component, wherein the first separation component is slidably connected to the shaft cylinder; The first linkage component is connected to the first cleaning component and the first separation component respectively. The first cleaning mechanism drives the first separation component through the first linkage component to tilt and squeeze the grass in the gap of the spiral component to separate it.

[0010] In a further embodiment, the first linkage component includes a sliding sleeve and an inclined column, one end of the inclined column is connected to a sliding shaft, and the sliding shaft is disposed in the sliding sleeve and slides along the length direction of the sliding sleeve; The other end of the inclined column is connected to the first separation component.

[0011] In a further embodiment, the first separation component includes a side arc block and an arc pressure plate that are slidably connected to the shaft cylinder; The side arc block is connected to the inclined block at the other end of the inclined column, and the side arc block is connected to the arc pressure plate.

[0012] In a further embodiment, a guide member is provided inside the shaft cylinder. The guide member includes a sleeve, which is fixed inside the shaft cylinder, and the other end of the inclined column is slidably connected to the sleeve.

[0013] In a further embodiment, the third cleaning mechanism and the second cleaning mechanism are located on both sides of the first cleaning mechanism; The third cleaning mechanism includes a second linkage component and a second separation component. The second linkage component is connected to the first cleaning component and the second separation component respectively. The first cleaning component drives the second separation component through the second linkage component to tilt, squeeze and separate the grass in the gap of the spiral component.

[0014] The second separation component includes an outer expansion plate, a side expansion plate, and a side top plate, all of which are arc-shaped. The inner arc surfaces of the outer expansion plate and the side expansion plate face the shaft cylinder. The inner arc surface of the side expansion plate is fixedly connected to the arc plate, and the inner arc surface of the outer expansion plate is fixedly connected to the arc groove.

[0015] In a further embodiment, the second linkage component includes a concave block, a sleeve shaft, and a linkage block; The concave block is fixed on the first cleaning mechanism, and one end of the sleeve shaft is rotatably connected to the concave block via a push shaft, while the other end is rotatably connected to the extrusion shaft. The extrusion shaft is fixed on the end of the arc-shaped groove away from the outer expansion plate, and one end of the linkage block is fixed on the arc-shaped groove, while the other end is fixed on the arc-shaped plate.

The battery supplies power to the power component, and the wireless controller controls the start and stop of the power component.

[0017] The beneficial effects of this invention are as follows: By setting up a multi-dimensional maintenance module, when a large amount of grass is wrapped around the spiral gap outside the shaft cylinder, the power component can drive the first cleaning mechanism to operate, thereby cutting the grass along the cutting groove opened on the spiral component. At the same time, the movement of the inclined blade can also drive the second and third cleaning mechanisms to operate, thereby enabling the grass to be separated by vertical and horizontal multi-directional inclined compression, achieving automatic multi-angle peeling of the grass in the spiral gap. The simultaneous operation of the three cleaning mechanisms can ensure that the grass is completely detached from the shaft cylinder, avoiding entanglement and secondary adhesion, effectively improving the time-saving and labor-saving self-maintenance of the soil-building device. Furthermore, the entire process of the operation of the three cleaning mechanisms can be completed by cutting, multi-dimensional tensioning and compression, and automatic separation with only a single power input from the power component, significantly improving the self-maintenance efficiency of the soil-building device.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1: Refer to Figure 1 and Figure 2 This embodiment discloses a spiral-type tobacco cultivation and hilling device, including a hilling assembly housed in a casing frame 1, and a multi-dimensional maintenance module for cleaning the hilling assembly. The hilling assembly includes a shaft cylinder 2 and a spiral component 3 wound around the outer wall of the shaft cylinder 2. A cutting groove 4 is formed on the spiral component 3 along the radial direction of the spiral component 3. The spiral component 3 is composed of several spiral blades distributed along the length direction of the shaft cylinder 2. Each spiral blade has a cutting groove 4 of the same size and interconnected at the same position, so that several cutting grooves 4 can simultaneously cooperate with a first cleaning mechanism. One end of the cutting groove 4 is connected to the interior of the shaft cylinder 2, and the other end is connected to the outside, so that the grass cut by the first cleaning mechanism can be pushed out from the opening position connected to the outside.

[0033] The multi-dimensional protection module includes a power component and a first cleaning mechanism slidably disposed in the shaft cylinder 2. The power component is disposed outside the shaft cylinder 2 and is used to drive the first cleaning mechanism to extend from the shaft cylinder 2 into the cutting groove 4 to cut the grass in the gap of the spiral component 3.

[0034] The first cleaning mechanism includes a slanted blade 8, the length of which matches the length of the spiral component 3. The length of the slanted blade 8 is set so that it can simultaneously cut the grass between several spiral blades. The slanted blade 8 slides from inside the shaft cylinder 2 into the cutting groove 4 along the radial direction of the shaft cylinder 2. It can not only cut the grass between the spiral blades, but also cut the grass near the cutting groove 4.

[0035] like Figure 4 As shown, the grooving cutter 8 is slidably connected to the slide plate 16, which is fixed inside the shaft cylinder 2. The slide plate 16 provides stable support for the sliding of the grooving cutter 8, and positions the grooving cutter 8 to ensure that it slides stably along the outer wall of the slide plate 16 and the radial direction of the shaft cylinder 2.

[0036] One end of the slanted cutter 8 is connected to the power assembly via a slide rod 7.

[0037] Specifically, the power assembly includes an electric cylinder 5 and a connecting bar 6 installed at the output end of the electric cylinder 5. The end of the slide rod 7 not connected to the inclined cutter 8 passes through the slide groove 28 and is connected to the connecting bar 6. (Refer to...) Figure 3 The connecting bar 6 is in the shape of an inverted "L". When the electric cylinder 5 is in its original state, that is, when the output end is not running, the distance between the slide bar 7 and the output end is the farthest. When the electric cylinder 5 is running, the output end pushes the connecting bar 6 away, causing the slide bar 7 to move and the slanted cutter 8 to move accordingly.

[0038] Furthermore, the groove 28 is formed on the shaft cylinder 2, and the slide rod 7 reciprocates in the groove 28 along the radial direction of the shaft cylinder 2 to drive the inclined groove cutter 8 in and out of the shaft cylinder 2.

[0039] like Figure 2 and Figure 3 As shown, in order to ensure the normal operation of the electric cylinder 5 included in the power assembly, an electric control component is provided at one end of the shaft cylinder 2. The electric control component is used to control the operation of the power assembly. One end of the shaft cylinder 2 extends out of the housing frame 1, and the shaft cylinder 2 is rotatably connected to the housing frame 1. The electric control component is provided at the end of the shaft cylinder 2 that extends out of the housing frame 1.

[0040] Furthermore, to protect the electronic control components, an outer cover 30 is provided on the housing frame 1. The outer cover 30 covers the outside of the electronic control components, power components, and the end of the shaft cylinder 2, thereby effectively protecting these components and preventing contamination of the grass and soil during the soil-laying process. Since the outer cover 30 is fixed to the housing frame 1, the rotation of the shaft cylinder 2, which drives the rotation of the electronic control components and power components, will not interfere with the outer cover 30.

[0041] The electronic control component includes a battery 27 and a wireless controller 29 connected to the power component. The battery 27 supplies power to the power component, and the wireless controller 29 receives signals from the central control unit to control the start and stop of the power component. Specifically, the battery 27 also supplies power to the wireless controller 29, ensuring that the wireless controller 29 can transmit and receive signals normally.

[0042] In order to enable the shaft cylinder 2 to rotate and drive the screw component 3 to carry out the soil filling operation, a drive motor 31 is provided on the housing frame 1. The drive motor 31 is connected to the shaft cylinder 2 to drive the shaft cylinder 2 to rotate.

[0043] Specifically, refer to Figure 1 The drive motor 31 and the electronic control components are located at both ends of the shaft cylinder 2, which makes the layout more reasonable and improves the balance of the device.

[0044] The implementation principle of this embodiment is as follows: During spiral hilling, the top of the machine frame 1 is bolted to the tractor's traction seat. The tractor pulls the machine frame 1, which in turn moves the drive motor 31. Simultaneously, the spiral component 3 is positioned in the hilling area of ​​the furrow during tobacco cultivation. The drive motor 31 then drives the shaft cylinder 2 to rotate, which rotates inside the machine frame 1. At the same time, the shaft cylinder 2 drives the spiral component 3 to rotate, bringing it into contact with the soil and thus achieving the hilling and loosening operation. This process effectively hills up the tobacco during cultivation.

[0045] When a large amount of grass becomes entangled in the outer spiral gap of the shaft cylinder 2, the drive motor 31 is stopped first. A separate battery 27 then powers the wireless controller 29 and the electric cylinder 5, wirelessly connecting the controller 29. The controller 29 activates the electric cylinder 5, which pushes the connecting bar 6 to move horizontally. The connecting bar 6 drives the sliding rod 7 to move horizontally, sliding along the inner wall of the groove 28. The sliding rod 7 drives the oblique cutting knife 8 to move horizontally, guided along the outer wall of the slide plate 16. Simultaneously, the oblique cutting knife 8 moves horizontally outward along the inner wall of the shaft cylinder 2 and enters the cutting groove 4, thus cutting the grass in the spiral gap of the outer wall of the shaft cylinder 2.

[0046] Example 2: Based on Example 1, the difference from Example 1 is that, referring to... Figure 5 and Figure 6 This embodiment discloses a spiral tobacco cultivation and hilling device. The first cleaning mechanism is also linked to a second cleaning mechanism. The second cleaning mechanism is used to cooperate with the first cleaning mechanism to push the grass away from the shaft cylinder 2, so as to prevent the grass from getting tangled and covering the shaft cylinder 2.

[0047] The second cleaning mechanism is provided with several sets, and the second cleaning mechanism includes a first linkage component and a first separation component, wherein the first separation component is slidably connected to the shaft cylinder 2.

[0048] The first linkage component is connected to the first cleaning component and the first separation component respectively. The first cleaning mechanism drives the first separation component through the first linkage component to tilt and squeeze the grass in the gap of the spiral component 3 to separate it.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, a groove is provided on the shaft cylinder 2 for placing the first separation component, allowing the first separation component to extend outward from the shaft cylinder 2 to squeeze and separate the grass. When the shaft cylinder 2 is in the process of rotating and soil-filling, the second separation component covers and closes the groove to prevent grass and soil from entering the shaft cylinder 2.

[0050] like Figure 7 As shown, the first linkage component includes a sliding sleeve 9 and an inclined column 11. One end of the inclined column 11 is connected to a sliding shaft 10, which slides within the sliding sleeve 9 along its length. The length direction of the sliding sleeve 9 is consistent with the radial direction of the shaft cylinder 2. The sliding sleeve 9 is a rectangular frame, and several sliding sleeves 9 are connected to one side of the inclined slot cutter 8. These sliding sleeves 9 are arranged sequentially along the axial direction of the shaft cylinder 2, and are perpendicular to the inclined slot cutter 8.

[0051] The other end of the inclined column 11 is connected to the first separation component. As the sliding shaft 10 slides up and down in the sliding sleeve 9, the angle between the inclined column 11 and the sliding sleeve 9 changes, thereby causing the first separation component to be driven by the inclined column 11 to squeeze and push away the grass.

[0052] Specifically, the first separation component includes a side arc block 15 and an arc pressure plate 14 that are slidably connected to the shaft cylinder 2. The side arc block 15 and the arc pressure plate 14 are staggered and there is an included angle between them. The included angle can be a right angle, an acute angle, or an obtuse angle, thereby enabling vertical and horizontal compression and separation of the grass.

[0053] The side arc block 15 is connected to the inclined block 13 connected to the other end of the inclined column 11, and the side arc block 15 is connected to the arc pressure plate 14. The side arc block 15 drives the arc pressure plate 14 to move downward along the inner wall of the shaft cylinder 2, and the arc pressure plate 14 begins to laterally tilt and squeeze the grass in the spiral gap to separate it.

[0054] Inside the shaft cylinder 2, a guide component is also provided. The guide component includes a sleeve 12, which is fixed inside the shaft cylinder 2. The other end of the inclined column 11 is slidably connected to the sleeve 12. The sleeve 12 is slidably attached to the outer wall of the inclined column 11 near the inclined block 13, and the bottom end of the sleeve 12 is fixedly connected to the shaft cylinder 2. The sleeve 12 is used for the inclined column 11 to move tilted. By the inclined column 11 tilting downward along the inner wall of the sleeve 12, it is ensured that the inclined column 11 moves steadily downward along a predetermined path.

[0055] The implementation principle of this embodiment is as follows: while the oblique groove knife 8 is pushed by the electric cylinder 5 to move outward of the shaft cylinder 2, the sliding sleeve 9 carries the sliding shaft 10 and moves downward at an angle. The sliding shaft 10 slides along the inner wall of the sliding sleeve 9, so that the oblique column 11 moves downward at an angle along the inner wall of the sleeve 12. The oblique block 13 drives the side arc block 15 to move downward at an angle. The side arc block 15 drives the arc pressure plate 14 to move downward at an angle along the wall of the shaft cylinder 2. This allows the side arc block 15 to vertically and obliquely squeeze and separate the grass in the spiral gap. The arc pressure plate 14 performs horizontal oblique and oblique squeezing and separating the grass in the spiral gap, so that the grass in the spiral gap can be separated in multiple dimensions while being cut.

[0056] Example 3: Based on Example 1, the difference from Example 1 is that the reference is... Figure 6 and Figure 8 This embodiment discloses a spiral tobacco cultivation and hilling device. The first cleaning mechanism is also linked to a third cleaning mechanism. The third cleaning mechanism is used to cooperate with the first cleaning mechanism to push the grass away from the shaft cylinder 2, so as to prevent the grass from getting tangled and covering the shaft cylinder 2.

[0057] The third cleaning mechanism and the second cleaning mechanism are located on both sides of the first cleaning mechanism.

[0058] The third cleaning mechanism includes a second linkage component and a second separation component. The second linkage component is connected to the first cleaning component and the second separation component respectively. The first cleaning component drives the second separation component through the second linkage component to tilt and squeeze the grass in the gap of the spiral component 3 to separate it.

[0059] Reference Figure 1 A groove is provided on the shaft cylinder 2 for placing the second separation component, so that the second separation component extends to the outside of the shaft cylinder 2. When the shaft cylinder 2 is in the process of rotating and soil-laying, the second separation component closes the groove to prevent grass and soil from entering the shaft cylinder 2.

[0060] like Figure 9 and Figure 10 As shown, the second separation component includes an outer expansion plate 22, a side expansion plate 26, and a side top plate 25, all of which are arc-shaped. The inner arc surfaces of the outer expansion plate 22 and the side expansion plate 26 are both facing the shaft cylinder 2. The inner arc surface of the side expansion plate 26 is fixedly connected to the arc plate 24, and the inner arc surface of the outer expansion plate 22 is fixedly connected to the arc-shaped groove 21. The side expansion plate 25 is fixed to the outer wall of the side top plate 25.

[0061] like Figure 10 and Figure 11 As shown, the side top plate 25 is installed on the outer wall of the arc plate 24. The side top plate 25 and the linkage block 23 are both fixedly connected to the arc plate 24. The length of the side expansion plate 26 is greater than the length of the side top plate 25. There is a gap between the side expansion plate 26 and the outer expansion plate 22.

[0062] The second linkage component includes a concave block 17, a sleeve shaft 19, and a linkage block 23.

[0063] The concave block 17 is fixed to the first cleaning mechanism. Specifically, as shown... Figure 6 As shown, the concave block 17 is fixed to the other side of the inclined slot cutter 8. One end of the sleeve shaft 19 is rotatably connected to the concave block 17 via the push shaft 18, and the other end is rotatably connected to the extrusion shaft 20. The center point of the push shaft 18 is lower than the center point of the extrusion shaft 20. The vertical cross-sectional shape of the arc-shaped groove 21 is arc-shaped.

[0064] like Figures 9 to 11 As shown, the extrusion shaft 20 is fixed on the end of the arc-shaped groove 21 away from the outer expansion plate 22, and one end of the linkage block 23 is fixed on the arc-shaped groove 21, and the other end is fixed on the arc-shaped plate 24.

[0065] The implementation principle of this embodiment is as follows: While the oblique groove cutter 8 moves outwards towards the shaft cylinder 2, it simultaneously drives the concave block 17 to move synchronously. This causes the concave block 17 to carry the push shaft 18 and move synchronously. The sleeve shaft 19 drives the extrusion shaft 20 upwards along an arc-shaped path. The arc-shaped groove strip 21 moves along the inner wall of the shaft cylinder 2 along an arc-shaped path. The outer expansion plate 22 extrudes and expands the grass in the spiral gap along an arc-shaped path. The arc-shaped groove strip 21 drives the linkage block 23 to move along an arc-shaped path, causing the arc-shaped plate 24 to extend outwards along the inner wall of the shaft cylinder 2. The side top plate 25 causes the grass in the spiral gap in the cutting edge area of ​​the oblique groove cutter 8 to expand and separate along an arc-shaped path. The side expansion plate 26 causes the grass in the spiral gap to separate from the outer wall of the shaft cylinder 2 at the upper part. Because the side expansion plate 26 is longer than the side top plate 25, it can cover and detach the grass in the spiral gap on the shaft cylinder 2 in two positions, preventing the cut grass from adhering to the shaft cylinder 2 and ensuring that the grass in the spiral gap is detached from the shaft cylinder 2, thus preventing the grass from getting tangled on the shaft cylinder 2. Finally, the shaft cylinder 2 is started by the drive motor 31, and the shaft cylinder 2 rotates inside the machine housing frame 1. The grass on the shaft cylinder 2 is flung out, quickly completing the automatic separation and preventing the grass that adhered after cutting from continuing to stick to the outer wall of the shaft cylinder 2.
