A soil ripping device with auxiliary wheels

Abstract

The application discloses a soil loosening device with auxiliary wheels and film uncovering function. The device comprises a mounting frame, walking wheels, supporting wheels and soil loosening blades. Before the film uncovering operation, the walking wheels are driven to rotate, and the device moves along the ridge. At this time, the soil loosening blades extend below the film and loosen the soil below the film as the device moves forward. When the operation starts, the film is placed on the supporting wheels. As the device moves forward, the supporting wheels and the soil loosening blades move synchronously, so that the film is continuously supported above the loosened soil, effectively avoiding pulling the film and the soil loosening blades cutting the film, and reducing the film residues in the soil. By arranging the supporting wheels on both sides of the walking wheels, the device can loosen the film on both ridges (single side) of the flue-cured tobacco at the same time, thereby improving the soil loosening efficiency.

Description

Technical Field

[0001] This application relates to the field of soil mulch treatment technology for flue-cured tobacco, and in particular to a mulch film removal and soil loosening device equipped with auxiliary wheels. Background Technology

[0002] Mulching is an agricultural technique that alters the crop growing environment by laying down a plastic film.

[0003] In tobacco cultivation, ridge planting and furrow planting are two common methods. When covering with plastic film, the film needs to be stretched taut and laid flat, so that it adheres tightly to the ridge (or furrow) surface or close to the ground, and the edges are pressed down firmly with soil. When the flue-cured tobacco grows to a certain stage, the film is removed in a timely manner. Before removing the film, common soil-loosening tools such as hoes are used to loosen the soil on the film. However, when using hoes to loosen the soil, it has been found that the film sticks to the soil, and the hoe is also very easy to cut the film, causing the torn film to become entangled with the soil, increasing the difficulty of film recycling, increasing the labor cost of removing the film, and also increasing the amount of film residue in the field. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a mulch film removal and soil loosening device equipped with auxiliary wheels to solve the problem of easily cutting the mulch film during soil loosening.

[0005] This application provides a plastic film removal and soil loosening device equipped with auxiliary wheels, including a mounting frame; a traveling wheel rotatably mounted on the mounting frame; a support wheel arranged side by side with the traveling wheel and rotatably mounted on the mounting frame for supporting the plastic film; and a soil loosening blade mounted on the mounting frame and located in front of the traveling wheel in the direction of travel for loosening the soil under the plastic film. At least one support wheel is provided on each axial side of the traveling wheel, and the mounting frame includes a main shaft on which the traveling wheel and all support wheels are mounted.

[0006] Based on the aforementioned mulch film removal and soil loosening device equipped with auxiliary wheels, before the film removal operation, the driving wheels are rotated, causing the device to move forward along the edge of the ridge. At this time, the soil loosening blade extends under the mulch film, loosening the soil beneath the film as the device moves forward. At the start of the operation, the mulch film is first placed on the support wheels. As the device moves forward, the support wheels and the soil loosening blade move synchronously, continuously rolling and supporting the mulch film above the loosened area, effectively preventing the mulch film from being pulled or cut by the blade, and reducing mulch film residue in the soil. Furthermore, by setting support wheels on both sides of the driving wheels, the device can simultaneously loosen the soil on two ridges (one side) of the tobacco field, thereby improving the soil loosening efficiency.

[0007] In one embodiment of the above-mentioned auxiliary wheel-equipped mulch film removal and soil loosening device, the main shaft includes a shaft body and at least one movable shaft. At least one end of the shaft body is provided with a threaded channel, and the outer side of the movable shaft is provided with an external thread that mates with the threaded channel. The movable shaft is provided with at least one support wheel.

[0008] In one embodiment of the above-mentioned auxiliary wheel mulch film removal and soil loosening device, at least two support wheels are provided on one axial side of the walking wheel, and at least one support wheel is slidably connected to the main shaft, and a folding tube structure is connected between two adjacent support wheels; the folding tube structure can be extended into a cylindrical shape to support the mulch film.

[0009] In one embodiment of the above-described device for removing and loosening soil using an auxiliary wheel for removing mulch film, the surface of the support wheel is detachably covered with an elastic layer.

[0010] In one embodiment of the above-described auxiliary wheel-equipped mulch film removal and soil loosening device, the mounting frame further includes a horizontal frame, and the soil loosening blade is detachably mounted on the end of the horizontal frame away from the traveling wheel.

[0011] In one embodiment of the above-described auxiliary wheel mulch film removal and soil loosening device, the horizontal frame includes a base and a base rotatably connected to the base, and the soil loosening blade is mounted on the base; wherein the base is rotatable about a horizontal axis to drive the soil loosening blade to rotate about the horizontal axis.

[0012] In one embodiment of the above-described auxiliary wheel mulch film removal and soil loosening device, the mounting frame extends upward at an angle to form an mounting cylinder, and an operating rod is inserted into the mounting cylinder.

[0013] In one embodiment of the above-described auxiliary wheel-equipped mulch film removal and soil loosening device, the operating lever includes a rod body and a sleeve rod sleeved on the outside of the rod body.

[0014] The above-described one or more embodiments of this application have at least one or more of the following beneficial effects:

[0015] Before removing the plastic film, the drive wheels rotate, moving the device forward along the edge of the ridge. At this time, the loosening blades extend under the plastic film, loosening the soil beneath it as the device moves forward. At the start of the operation, the plastic film is first placed on the support wheels. As the device moves forward, the support wheels and the loosening blades move synchronously, continuously rolling and supporting the plastic film above the loosened area. This effectively prevents pulling on the plastic film and the blades from cutting it, and reduces the amount of plastic film residue in the soil. Furthermore, by installing support wheels on both sides of the drive wheels, the device can simultaneously loosen the soil on two ridges (one side) of the tobacco field, thus improving loosening efficiency.

[0016] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0026] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0027] Currently, mulch film is often used in tobacco cultivation. However, the film is often cut during the removal process, which makes it more difficult to recycle and increases the amount of film residue in the field.

[0028] Therefore, this application creatively proposes a plastic film removal and soil loosening device equipped with auxiliary wheels. The device includes a mounting frame, traveling wheels, support wheels, and loosening blades. Before the film removal operation, the traveling wheels are driven to rotate, causing the device to move forward along the edge of the ridge. At this time, the loosening blades extend under the plastic film and loosen the soil beneath the film as the device moves forward. At the start of the operation, the plastic film is first placed on the support wheels. As the device moves forward, the support wheels and loosening blades move synchronously, thus continuously rolling and supporting the plastic film above the loosened area, effectively preventing the film from being pulled or cut by the loosening blades, and reducing the amount of film residue in the soil.

[0029] The present application will be described in detail below through specific embodiments.

[0030] Reference Figures 1 to 6 As shown in the figure, this application embodiment provides a mulch film removal and soil loosening device equipped with auxiliary wheels. The device includes a mounting frame 1, a traveling wheel 2, a support wheel 3, and a soil loosening blade 7. The traveling wheel 2 is rotatably mounted on the mounting frame 1. The support wheel 3 is arranged side by side with the traveling wheel 2 and is rotatably mounted on the mounting frame 1 to support the mulch film. The soil loosening blade 7 is mounted on the mounting frame 1 and is located in front of the traveling wheel 2 in the direction of travel to loosen the soil under the mulch film.

[0031] It is understandable that the shape of the mounting bracket 1 can be made of various profiles that meet the requirements of structural strength and lightweighting, such as bent plates or standard profiles (such as square tubes and angle steel). Its specific form can be designed according to actual production needs and processes.

[0032] The shape of the soil loosening blade 7 is not limited to regular shapes such as cuboids or U-shaped plates, but can also be other irregular shapes. Its core design feature is that it can effectively loosen the soil without cutting the above-ground mulch film under normal operating conditions. In this embodiment, the soil loosening blade 7 is roughly cuboid in shape, but its back part is thicker to ensure structural strength, while the cutting edge part is thinner to facilitate cutting into the soil.

[0033] It should be noted that, given the thinness and fragility of the mulch film, if a rigid support structure that cannot rotate relative to the mulch film is used, the mulch film is very likely to be pulled or even torn due to excessive friction during the movement of the device.

[0034] Before removing the plastic film, drive the traveling wheels 2 to rotate, moving the device forward along the edge of the ridge. At this time, the loosening blades 7 extend under the plastic film, loosening the soil beneath it as the device moves forward. At the start of the operation, the plastic film is first placed on the support wheels 3. As the device moves forward, the support wheels 3 and the loosening blades 7 move synchronously, continuously rolling and supporting the plastic film above the loosened area, effectively preventing the film from being pulled or cut by the loosening blades 7, and reducing the amount of film residue in the soil.

[0035] Furthermore, in some examples, refer to Figure 1 As shown, at least one support wheel 3 is provided on each of the two axial sides of the traveling wheel 2.

[0036] It should be noted that when planting flue-cured tobacco, there are generally at least two rows. Therefore, the above setup allows the device to simultaneously loosen the soil around the mulch film on both rows (one side), thereby improving the soil loosening efficiency and ultimately increasing the efficiency of film removal.

[0037] It is understood that the number of support wheels 3 can be two or more, depending on the width of the mulch film to be removed. In this embodiment, a support wheel 3 is provided on each side of the walking wheel 2. To further improve the stability and efficiency of the device's movement, the support wheels 3 on both sides of the walking wheel 2 can be stacked around the walking wheel 2.

[0038] In some examples, refer to Figure 1 As shown, the mounting frame 1 includes a main shaft 4, on which the traveling wheels 2 and all the support wheels 3 are mounted. In this embodiment, the traveling wheels 2 and all the support wheels 3 are rotatably mounted on the main shaft 4. By mounting the traveling wheels 2 and all the support wheels 3 on a single shaft, both the structural strength and the coordination of their movements can be improved, thereby reducing the possibility of the mulch film being pulled by the support wheels 3.

[0039] In this embodiment, the centerline of the blade back is on the same horizontal plane as the axis of the main shaft 4, so as to keep the soil loosening depth consistent.

[0040] Furthermore, in some examples, refer to Figure 2 As shown, the main shaft 4 includes a shaft body 41 and at least one movable shaft 42. At least one end of the shaft body 41 is provided with a threaded channel 411, and the outer side of the movable shaft 42 is provided with an external thread that mates with the threaded channel 411. At least one support wheel 3 is provided on the movable shaft 42.

[0041] When the device is used in scenarios with different ridge widths, the total length of the main shaft 4 can be changed by rotating the movable shaft 42, thereby changing the distance between the adjusting movable wheel and the walking wheel 2, so that the support wheel 3 can effectively extend under the mulch film to stably support the mulch film.

[0042] In some examples, refer to Figure 3 As shown, at least two support wheels 3 are provided on one axial side of the walking wheel 2, and at least one support wheel 3 is slidably connected to the main shaft 4. A folding tube structure 5 is connected between two adjacent support wheels 3. The folding tube structure 5 can be extended into a cylindrical shape to support the mulch film. In this embodiment, the folding tube structure 5 is made of multiple layers of V-shaped cardboard or other thin sheets with good plasticity.

[0043] By moving the distance between two adjacent support wheels 3, the folding cylinder structure 5 can be unfolded to increase the support area for the mulch film, thereby adapting to loosening operations with different ridge widths.

[0044] In some examples, refer to Figure 2 As shown, an elastic layer 6 is detachably fitted onto the surface of the support wheel 3. In this embodiment, the elastic layer 6 is a rubber layer, but it can also be other elastic plastic layers.

[0045] The connection between the elastic layer 6 and the support wheel 3 can be achieved through a sleeve, snap-fit, or threaded connection. For example, countersunk holes can be made in the elastic layer 6, and blind holes in the support wheel 3, followed by bolt fixing. In this embodiment, the elastic layer 6 and the support wheel 3 are connected using a Velcro fastener, where a hook surface is provided on the outer circumference of the support wheel 3, and a soft surface is provided on the inner circumference of the elastic layer 6, allowing for quick replacement of the elastic layer 6. The elastic layer 6 not only reduces the possibility of pulling on the mulch film but also allows for adjustments to the thickness of the elastic layer 6 to meet different height support requirements for the mulch film.

[0046] In some examples, refer to Figure 1 As shown, the mounting frame 1 also includes a horizontal frame 11, and the tumbler blade 7 is detachably mounted on the end of the horizontal frame 11 away from the traveling wheel 2.

[0047] By changing the soil loosening blades 7 to different specifications (including size and material), it is possible to effectively meet the needs of operations in different environments, such as hard and soft soil.

[0048] Furthermore, in some examples, refer to Figure 4 As shown, the horizontal frame 11 includes a base 111 and a base 112 rotatably connected to the base 111, and the soil loosening blade 7 is mounted on the base 112; wherein, the base 112 can rotate around a horizontal axis to drive the soil loosening blade 7 to rotate around the horizontal axis.

[0049] Because of differences in soil slope and other factors, the working angle of the loosening blade 7 can be changed by altering its angle, thereby improving its loosening efficiency.

[0050] In some examples, refer to Figure 5 As shown, the mounting frame 1 extends upward at an angle to form a mounting cylinder 12, and an operating lever 13 is inserted inside the mounting cylinder 12. The operating lever 13 is designed to be more ergonomic and facilitates the operation of the auxiliary wheel-equipped film removal and soil loosening device.

[0051] Furthermore, in some examples, refer to Figure 6As shown, the operating lever 13 includes a lever body 131 and a sleeve 132 sleeved on the outside of the lever body 131. In this embodiment, the sleeve 132 is threadedly connected to the lever body 131. By screwing the sleeve 132, the total length of the operating lever 13 can be changed, thereby adapting to operators of different heights.
